[0002] The wire-releasing equipment in the carbon fiber production line generally has hundreds or even thousands of wire-releasing shafts. Therefore, the electrical control panels of the electrical control system corresponding to the wire-releasing equipment are usually modular and large in number. At present, most domestic manufacturers of carbon fiber wire-releasing equipment use two methods: workshop personnel to conduct simple functional tests or go to the site for trial and error debugging. In the early testing work of workshop personnel, a large number of control lines of each electrical control board were manually wired one by one, unplugged, parameters were manually checked, and parameters were set. The test efficiency was extremely low, and it was easy to cause problems such as missed functions, wrong tests, and inadequate component inspections, and the factory quality of the products was difficult to guarantee; including the traditional method of sending to the site for trial and error debugging, the problems of hundreds or thousands of electrical control boards on site and various problems of peripheral lines were mixed together, resulting in difficulty in on-site debugging, time-consuming, high on-site personnel costs, and in terms of equipment quality, it gave customers a poor impression, which greatly affected the reputation of manufacturing companies. In recent years, with the rise of lightweight trends and the development of high-end manufacturing, the carbon fiber market has shown a rapid growth trend. The demand for carbon fiber continues to increase both at home and abroad, and orders for carbon fiber unwinding equipment are also increasing rapidly.

[0017] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0018] Embodiment: A test platform for detecting an electrical control board of a carbon fiber laying device, such as Figure 1-Figure 3 As shown, it includes a cabinet, a power supply socket and a platform power switch are installed on the right side of the cabinet, a mounting hole for installing a cooling system is opened on the left side of the cabinet, the upper end of the cabinet includes a horizontal operating surface and a vertical operating surface, the horizontal operating surface is provided with a test platform plane, the test platform plane includes a signal connection area and a test operation knob, the vertical operating surface is provided with a power output area and a touch screen, the front side of the horizontal operating surface is provided with a temporary cable hanging plate, the signal connection area includes six groups of motor line quick-connect sockets and encoder line quick-connect sockets and three groups of limit angle signal line sockets.

[0019] The test platform includes a test quick-plug terminal, and the side of the test quick-plug terminal is provided with concave and convex slots that can be plugged into each other; the bottom of the cabinet is provided with a lockable universal wheel; the front end of the cabinet is equipped with a cabinet door; the interior of the cabinet is equipped with a storage tray and an instrument document box.

[0020] Principle of the utility model:

[0021] (1) Connect the external power supply to the power input of the test platform. Next, connect the power output area 9 of the test platform to the electrical control board through a three-hole plug wire; the communication network cable is connected to the controller network port through the network port of the power output area 9 to realize internal information interaction; one end of the signal line such as the limit, angle tension, and control alarm in the signal connection area 7 is connected to the male head of the signal cable quick plug connector through the quick plug female socket on the test platform, and no plugging and unplugging is required during testing; the other end of the signal line is connected to each signal terminal row on the control board through the test quick plug terminal 15; the test quick plug terminal 15 can be connected to the test socket of the terminal row without affecting the wiring of the control board, and has the function of quick plugging and unplugging, which greatly saves test time and improves test efficiency. In addition, there are concave and convex slots 16 on the side of the test quick plug terminal 15, which can be spliced ​​at will; there is a direct plug-in cable interface at the top, and the cable can be directly inserted into the test quick plug terminal 15 without using other tools. Different combinations of splicing tests are performed according to the actual terminal arrangement of different control boards, which greatly increases the test flexibility and versatility. At this point, the power supply and communication functions between the test platform and multiple test boards have been opened.

[0022] (2) On the left side of the test platform slope is the power output area 9. The test platform can perform functional tests on 6 controllers at a time. If there are 2 controllers on an electrical control board, then 3 electrical control boards can be tested at one time, and the power output area 9 leads to 3 independent power supplies to supply power to the 3 electrical control boards respectively; if there are 6 controllers on an electrical control board, then 1 electrical control board can be tested at one time, and the power output area 9 leads to 1 independent power supply to supply power to 1 electrical control board, and so on for other situations. On the right side of the test platform slope is the touch screen 10, which can centrally control and display the test status of the test platform.

[0023] (3) The left side of the test platform plane is the signal connection area 7, which contains 6 sets of quick-connect sockets for motor lines and encoder lines. In the middle are 3 sets of limit angle signal line sockets 14 and button box line sockets 21. The right side of the test platform plane is the manual test operation area. After connecting the power and signal cables between the test platform and the control board, the angle analog signal, upper limit, lower limit, manual and automatic simulation test can be performed. The test steps are as follows: turn on the power switch on the side of the test platform and close the protection circuit breaker of the power output area 9 to power on the control board. Next, the upper and lower limit digital signals, angle analog signals, motor and encoder signals and other communication tests are performed through the test operation area on the test platform; next, turn the upper and lower limit knobs to the right in turn to test whether the upper and lower limit functions are normal; turn the angle knob to the right in turn to test whether the angle analog function is normal; then, by rotating the control knob to the left and right respectively, it is possible to check whether the external control circuit, controller, motor and other components are working normally and whether the circuit board function is normal. Through a series of tests, it is possible to check whether the electrical control board components, controllers, protection elements, signal terminal blocks, etc. are faulty or have any wrong or missing connections.

[0024] (4) When the test cable's test quick-plug terminal 15 is not in use, the cable can be inserted into the temporary cable hanging plate 11 in front of the test platform, and cables with different functions can be arranged in order to make the cables orderly, which is convenient for continued testing later. This avoids the situation where the traditional test platform has many and disorderly cables during testing, and the cables have to be searched for before the next test. This function of the temporary cable hanging plate 11 saves a lot of testing time and speeds up the test. The cable temporary placement front plate is fixed to the test platform by screws passing through the gourd hole. When this plate is not needed, the disassembly work can be completed by loosening the screws without removing the screws, which is convenient for personnel to install and disassemble.

[0025] (5) The operation signal of the test operation area is transmitted to the control panel controller through the test cable. After processing, the controller feeds back the signal to the PLC control system inside the test platform through the upper and lower limit signal terminals, the angle analog signal terminal, and the control and alarm signal terminal. The touch screen 10 collects the information summarized by the PLC control system and displays it on the touch screen 10, thereby realizing the unified display of various signals. This avoids the need to confirm the motor status here and the analog signal there in the traditional detection method, thereby reducing the workload and activity of personnel and enabling them to pay better and more focused attention to the test status.

[0026] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
