Factory production line MES touch screen computer

The factory production line MES touch screen computer is an industrial integrated computing terminal deployed at the production station site, serving as the physical carrier of MES (Manufacturing Execution System) extending to the workshop, carrying key functions such as operation guidance, data collection, work report confirmation, equipment linkage, etc., and is the core hardware bridge connecting the production planning layer and the on-site execution layer.

🏭  Product characteristics: closely follow the working condition of production line station

The core constraints of the production line station environment focus on three dimensions: continuous dust and oil erosion, 7 × 24 hours non-stop operation, and parallel access of multiple peripherals. All designs of MES station terminals are based on these rigid demands.

Industrial protection and fanless passive cooling

The production line environment is generally filled with dust, oil mist and cutting fluid splash. The front panel of the MES station terminal usually reaches IP65 protection level, which can completely isolate dust intrusion and resist low-pressure water jet. Workers can directly clean the screen surface with rags or even spray pots. The whole machine widely adopts the fanless passive cooling design, which fundamentally eliminates the hidden trouble of mechanical failure, greatly reduces the equipment failure caused by dust accumulation, and the mean time between failures is significantly better than that of ordinary commercial equipment. In the severely polluted workshop, the annual maintenance cost of IP65 is about 60% lower than that of IP54, and the service life is extended by 2-3 years.

Wide temperature range operation and wide voltage supply

The ambient temperature of the workshop fluctuates violently. The working temperature range of the MES station terminal generally covers -20 ° C~60 ° C, and some models can be expanded to -30 ° C~70 ° C. The power supply supports a wide voltage input of 12~24V, effectively responding to the fluctuations of the factory power grid, and ensuring continuous and stable operation in the high-temperature workshop or low-temperature storage environment in summer without air conditioning.

Rich industrial I/O interfaces

The MES station terminal needs to interface with PLC, code scanning gun, printer, sensor, industrial camera and other peripherals synchronously. Typical interface configuration covers: 2 gigabit network ports (supporting channel separation between MES data network and equipment network); Multiple RS-232/485 serial ports (support mainboard jumper switching, direct connection to PLC and barcode scanner); 4 or more USB 3.0 interfaces (access to USB flash disk, camera, etc.); And HDMI display output (support external large screen board for data display).

Gloved touch control and HD display

Production line workers usually wear gloves when operating. MES station terminals are generally equipped with 10 point capacitive touch screens, which support glove wearing precise touch and gesture zoom operations. The screen resolution is usually 1920 × 1080, and the brightness is between 220~350 cd/m ², ensuring that the text, engineering drawings and even 3D model animation on the operation instructions can be clearly presented under the normal lighting conditions of the factory.

⚙️  Core functions

As the physical extension of MES, WMS and other application systems on site, MES station terminal undertakes the following key functions:

Operation instruction (electronic SOP)

Push the work instructions corresponding to the work order to the station terminal through the MES system, completely replacing the paper documents. Workers can check the high-definition 3D assembly animation, process parameters and quality inspection standards in front of the station, and switch the version with one button when changing lines, so as to eliminate the risk of taking wrong documents from the source. The line change time can be reduced from tens of minutes in the traditional way to about 30 seconds, and the efficiency is significantly improved.

Data acquisition and work reporting

After the operator completes the current process, he can confirm the work report with one key through the touch screen, and the production progress is updated in real time and uploaded to the MES system synchronously. All data are collected at the same terminal to ensure the integrity and real-time of the production data link.

Process error proofing

The system implements forced control over the process flow - the previous process is not confirmed, and the next process cannot be started, effectively preventing "skip station" operation. Some high-end models are also equipped with customizable physical function buttons (with LED backlight). The operator must click to confirm step by step before the screen can unlock the next operation guide.

Device interaction and status monitoring

Directly connect PLC through serial port or Ethernet to read equipment operation status, output count, alarm information and other data in real time, upload them to MES server after preliminary processing at the terminal side, and form a complete data link of equipment layer → station layer → management layer.

Lamp calling and material pulling

The station terminal can integrate the Andon call function. Workers can initiate four kinds of calls for materials/quality/equipment/personnel through the touch screen or physical keys. The system links the audible and visual alarm device and synchronously pushes it to the AGV dispatching system to achieve closed-loop management of abnormal response.

🏭  Typical application scenarios

Auto parts and assembly production line

In the auto parts workshop, the MES workstation terminal displays the production goal and yield trend chart of the day in real time, so that workers can intuitively grasp the task priority; The team leader tracks the status of multiple stations synchronously through the centralized monitoring platform, and quickly allocates resources to break through the bottleneck process. In the final assembly line, the assembly workers receive the task list in real time on the station touch screen, and the system automatically verifies the matching after scanning the barcode of the parts, so as to eliminate the wrong loading of materials from the source; Key torque data is automatically collected by intelligent tools and bound to the vehicle VIN code to achieve the traceability of the whole process quality.

Electronic Assembly and Discrete Manufacturing

The station terminal of the electronic assembly line deploys the Web version MES system to realize the electronic and intelligent management of the station work instructions. The workers look up the high-definition 3D assembly animation, process parameters and quality inspection standards through the IPC in front of the station, and confirm the completion of the process with one key. The equipment shall support 7 × 24 hours non-stop operation, and be equipped with RS-232 serial port to connect existing industrial equipment (such as PLC, barcode scanner, printer) for data acquisition or communication, taking into account the compatibility of new system deployment with old equipment.

Textile Printing and Dyeing and Process Manufacturing

In the intelligent transformation of the dyeing and weaving factory, MES workstation terminal, as an intelligent terminal connecting the production line and the enterprise management system, is used for standardized data collection, intelligent work order management and production factor monitoring to help enterprises carry out production scheduling in an orderly manner, improve the primary dyeing rate, and comprehensively improve the manufacturing execution and management transparency.

New energy battery and chemical production line

In order to open up the data channel between the workshop site and the MES system, a leading beer enterprise deployed on-site human-computer interaction terminals in multiple core production lines such as filling and brewing, so that front-line personnel could directly complete parameter retrieval, work order confirmation, exception reporting, and batch information query at the production line points, realizing transparent and controllable production processes. In the chemical workshop, the IP65 full protection model can resist the splashing of corrosive gas and liquid, and ensure continuous and stable operation under severe conditions.
