[0002] With fierce competition in the tractor market, efficiency and quality in tractor production are becoming increasingly important. Automated equipment used in factory assembly is becoming increasingly prevalent. During the assembly of a single shaft in tractor production, a combination of shims is selected from a stock of 10 sizes (0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1.0mm) based on the difference between the bearing seat seam depth (L1) and the bearing protrusion height (L2). Currently, manual measurements, recording, and calculations are performed using calipers, and the selected shims are determined manually.

Binding to the product serial number (SN) presents challenges, and manual shim calculations are prone to errors. Furthermore, the type and quantity of selected shims are difficult to record and archive. These issues severely impact production efficiency and product quality, making it impossible to trace product problems. Utility Model Content

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as limiting the scope of protection of the present invention.

[0018] like Figure 1 As shown, a gasket automatic selection device includes: an industrial computer 3, a workbench 11, an electronic caliper 1, a barcode scanner 2 and a display 4. The electronic caliper 1, the barcode scanner 2 and the display 4 are respectively connected to the industrial computer 3 for communication. Gaskets of various sizes are placed on the workbench 11. The electronic caliper 1 is used to measure the size of the product to be assembled, and the barcode scanner 2 is used to scan the serial number of the product to be assembled.

[0019] After calculating the dimensional data signal sent by the electronic caliper 1, the industrial computer 3 sends the shim selection result to the display 4 for display. The shim selection result is then bound to the product serial number sent by the barcode scanner 2 and stored in the memory. A host computer program is pre-programmed on the industrial computer 3 and sets the types of shims to be used among the multiple types. After receiving the measured data, the host computer program calculates the recommended shim type and corresponding quantity based on the pre-programmed algorithm and displays it on the display 4. The selection result is the type and quantity of shims required. The memory is specifically the local hard disk of the industrial computer 3.

[0020] In a practical application, the product to be assembled is a bearing seat and bearing for a tractor shaft. The measured bearing seat seam depth L1 and bearing protrusion height L2 are sent to industrial computer 3, which calculates the difference between L1 and L2. Based on the available shim inventory, industrial computer 3 selects a combination of several of these shims and sends them to display 4 for display. The automatic calculation and recommendation of the type and quantity of shims used by industrial computer 3 eliminates the inefficiency and error-proneness of manual recording and calculation, improving product quality and production efficiency.

[0021] The industrial computer 3 can also program the upper and lower limits for the measured data parameters L1 and L2, as well as the standard value for the difference between L1 and L2. If the measured L1 and L2 parameters exceed the set upper and lower limits, the display 4 or alarm module will indicate an incoming material anomaly, output a product failure determination, and discontinue assembly. If the difference between L1 and L2 exceeds the set standard, the display 4 or alarm module will prompt the operator to replace the product to be assembled and re-measure.

[0022] Preferably, a plurality of shim bins 8 are provided on the workbench 11, and each shim is placed in a different shim bin 8 according to its size. The shim bin 8 is provided with a silo door 9, and the silo door 9 is provided with an electromagnetic lock 10. When the display 4 shows the result of the shim selection, the electromagnetic lock 10 of the corresponding shim bin 8 is opened. A plurality of indicator lights 7 are also provided on the workbench 11, and each indicator light 7 is installed on the outer frame of each shim bin 8 in a one-to-one correspondence. Each indicator light 7 is electrically connected to the controller, and the indicator light 7 is used to indicate the selected shim. Only the electromagnetic lock 10 of the silo door 9 of the automatically recommended shim will be opened, and only the corresponding indicator light 7 will light up. Therefore, the shim bin 8 has a good error-proofing function.

[0023] Further preferably, the electronic caliper 1 is a wireless caliper, and the barcode scanner 2 is a wireless barcode scanner. The wireless caliper and the wireless barcode scanner are respectively wirelessly connected to an industrial computer 3. The industrial computer 3 is communicatively connected to a controller, and the controller is electrically connected to the electromagnetic lock 10. Specifically, the controller is a PLC controller 5. After receiving the type and quantity of the gaskets selected from the industrial computer 3, the PLC controller 5 outputs a signal to control the peripheral circuit through a written program, thereby opening the corresponding electromagnetic lock 10 and lighting the indicator light 7.

[0024] Specifically, the electromagnetic lock 10 and indicator light 7 are connected to the PLC controller 5 via wires. The PLC controller 5 communicates serially with the industrial computer 3 via a network cable. The display 4 is connected to the industrial computer 3 via a VGA (Video Graphics Array) cable. The wireless caliper and wireless barcode scanner are connected to the industrial computer 3 via Bluetooth. The industrial computer 3, controller, and display 4 are each electrically connected to a power supply 6.

[0025] The working principle of the automatic gasket selection device in this application is as follows:

[0026] The dimensions L1 and L2 are transmitted to the industrial computer 3 using a wireless caliper. After calculation and analysis by the algorithm of the host computer program, the type and quantity of gaskets to be used are automatically selected and recommended, and the analysis results are transmitted to the display 4 in real time. The recommended results and the serial number sent by the wireless barcode scanner 2 are saved to the local hard disk of the industrial computer 3. The operator can view the type and quantity of gaskets selected in real time through the display 4, and can also query the historical data of gasket selection. The host computer transmits the results of the type and quantity of gaskets selected to the PLC controller 5 through serial port communication. According to the received results, the PLC program controls the electromagnetic lock 10 of the peripheral gasket bin 8 to open the silo door 9 of the gasket of the corresponding size, and turns on the indicator light 7 of the gasket bin 8 of the corresponding size.

[0027] The automatic gasket selection device of the present invention is provided with an industrial computer, a workbench, an electronic caliper, a barcode scanner and a display. The industrial computer calculates the size data signal of the product to be assembled sent by the electronic caliper and sends the gasket selection result to the display for display. The gasket selection result is bound to the serial number of the product sent by the barcode scanner and stored in the memory, thereby improving the quality and production efficiency of the product. At the same time, the gasket selection data during assembly is recorded in real time for easy traceability.
