Description

Production line tray device Technical Field

[0001] This utility model relates to the field of electrical control testing technology, specifically to a production line tray device. Background Technology

[0002] Electrical control testing technology refers to the technical system for testing, verifying and evaluating the function, performance and reliability of electrical control systems (such as motor drives, power management, automation equipment, etc.). Its core objective is to ensure that the electrical control system meets the expected electrical parameters, control logic and safety standards in the design, manufacturing and operation stages.

[0003] Existing electronic control testing technology has complex production carrier structures. Different three-phase AC power supply interfaces, two-phase high-voltage DC interfaces, and resolver structures on matching circuit boards need to be designed according to the product's test interface. At the same time, water cooling of the product's water circuit is also required during the test. Since different electronic control products have different interfaces, each product often requires a separate carrier design. The carrier is expensive and difficult to transport. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a production line carrier device that features advantages such as rapid switching of water flow direction, multi-directional compatibility, and adaptive connection, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a production line tray device, including a base, a frame above the base, an upper pressure plate hinged to the right end of the frame, a water channel assembly between the frame and the upper pressure plate, the water channel assembly including two water inlets installed on the upper surface of the base and a water inlet installed on the upper surface of the upper pressure plate, and a water inlet switching valve installed on the upper surface of the frame.

[0006] The upper surface of the upper pressure plate is equipped with a high-voltage wiring harness assembly and a clamping assembly. The high-voltage wiring harness assembly includes two DC high-voltage plugs. The upper surface of the base frame is equipped with a three-phase high-voltage copper busbar. The input ends of the two DC high-voltage plugs and the three-phase high-voltage copper busbar are all equipped with resolver wiring harness interfaces. The upper surface of the DC high-voltage plugs is fixedly connected with elastic traction ropes. The other ends of the two elastic traction ropes are fixedly connected to the upper pressure plate.

[0007] Through the above solution, the water circuit component achieves efficient circulation and flexible path switching of water flow between multiple channels by means of an innovatively designed inlet switching valve, which significantly improves the exchange speed and system response efficiency.

[0008] Furthermore, the clamping assembly includes multiple brackets mounted on the upper surface of the upper pressure plate. A positioning rod is slidably inserted into the upper surface of each bracket. Each positioning rod penetrates the upper pressure plate. The bottom end of each positioning rod is made of rubber. A cam is rotatably connected to the inner wall of each bracket. A handle is fixedly connected to the outer surface of each cam.

[0009] The above solution uses positioning rods to fix the circuit board, ensuring stable contact with the base frame and maintaining a stable state during testing.

[0010] Furthermore, an automatic docking plate is installed on the upper surface of the base. The upper surface of the automatic docking plate is provided with multiple circuit interfaces of different types. An inlet valve and an outlet valve are installed on the upper surface of the automatic docking plate. The bottom end of the inlet valve is fixedly connected to the input end of the front water outlet one through a hose. The bottom end of the outlet valve is fixedly connected to the input end of the water outlet switching valve through a hose. The first output end of the water outlet switching valve is fixedly connected to the input end of the second water outlet above the hose. The second output end of the water outlet switching valve is fixedly connected to the first water outlet located at the rear through a hose.

[0011] The above solution, by setting a water inlet switching valve to switch the water flow path, can achieve cooling work on different types of circuit boards, making the whole system adaptable to different types of circuit boards for testing.

[0012] Furthermore, the three-phase high-voltage copper busbar and the resolver harness interface on the rear DC high-voltage plug are both threadedly connected with wires, and the other end of each wire is electrically connected to the bottom input end of the automatic docking plate. The bottom output end of the automatic docking plate is electrically connected to a low-voltage connector via wires.

[0013] The above solution uses a resolver harness interface to connect the wires, which facilitates quick disassembly and assembly of the wires, meeting the need for quick replacement while ensuring structural stability.

[0014] Furthermore, two buckles are fixedly connected to the upper surface of the base frame. Both buckles are made of elastic material, and the protruding parts at the upper ends of the two buckles are in contact with the upper pressure plate.

[0015] The above solution allows the buckle to fix the upper pressure plate after it is flipped, ensuring that the upper pressure plate remains stable. At the same time, the buckle limits the movement of the upper pressure plate and keeps it level with the base frame.

[0016] Furthermore, multiple positioning posts are fixedly connected to the upper surface of the base frame and the bottom end of the upper pressure plate.

[0017] The above solution allows for the positioning of circuit boards by setting up positioning posts, making it easier for staff to place the circuit boards in the appropriate positions.

[0018] Furthermore, the bottom end of the upper pressure plate is slidably connected to a shaped plate, and the bottom end of each positioning rod is provided with a positioning groove, with the shaped plate located in each positioning groove.

[0019] The above solution allows the irregularly shaped plate to be inserted into the positioning groove after sliding, enabling the simultaneous positioning of multiple positioning rods, keeping them in contact with the circuit board, and thus positioning the circuit board.

[0020] Furthermore, a motor is mounted on the upper surface of the upper pressure plate, and a gear is fixedly connected to the output shaft of the motor. A set of teeth is fixedly connected to the front end of the irregular plate, and the gear meshes with the adjacent teeth.

[0021] By using the above scheme, the gear and teeth are matched so that when the motor drives the gear to rotate, the gear can drive the irregular plate to slide at the bottom of the upper pressure plate, and after sliding, it enters multiple positioning grooves to limit the positioning rod.

[0022] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0023] The tray carrier device of this production line utilizes an innovatively designed water inlet switching valve to achieve efficient circulation and flexible path switching of water flow between multiple channels, significantly improving the commutation speed and system response efficiency. Secondly, the DC high-voltage plug adopts a floating structure design, which can adapt to the connection requirements of different positions, ensuring high-precision docking while effectively compensating for assembly tolerances and improving system reliability. Finally, the clamping component applies uniform pressure to the circuit board between the base frame and the upper pressure plate through flexible clamping, ensuring the stability of the circuit board during high-speed operation and avoiding surface damage or deformation caused by traditional rigid clamping. The entire system integrates four core advantages: rapid switching, multi-directional compatibility, adaptive connection, and non-destructive clamping, improving production efficiency while fully protecting key components, achieving a dual breakthrough in performance and reliability.

By setting the water inlet switching valve 403 to switch the flow path of the water, it is possible to cool different models of circuit boards, so that the whole system can be adapted to different models of circuit boards for testing.

[0048] Please refer to Figures 1, 2, and 3. The three-phase high-voltage copper busbar 502 and the resolver harness interface 503 on the rear DC high-voltage plug-in 501 are both threadedly connected with wires 11.

[0049] Please refer to Figures 1, 2, and 5. Multiple positioning posts 14 are fixedly connected to the upper surface of the base frame 2 and the bottom end of the upper pressure plate 3. The positioning posts 14 position the circuit board, facilitating placement by the operator. A shaped plate 15 is slidably connected to the bottom end of the upper pressure plate 3. Each positioning rod 602 has a positioning groove 16 at its bottom end, with the shaped plate 15 located within each groove 16. The shaped plate 15 can be inserted into the positioning groove 16 after sliding, allowing for simultaneous positioning of multiple positioning rods 602.

A gear 18 is fixedly connected to the output shaft of the motor 17. A set of teeth 19 is fixedly connected to the front end of the irregular plate 15. The gear 18 meshes with the teeth 19 that are close to it. The engagement of the gear 18 and the teeth 19 is set so that when the motor 17 drives the gear 18 to rotate, the gear 18 can drive the irregular plate 15 to slide at the bottom end of the upper pressure plate 3. After sliding, it enters multiple positioning grooves 16 to limit the positioning rod 602.

[0050] The working principle of the above embodiment is as follows: When testing the circuit board, the circuit board is first placed on the base frame 2, then the upper pressure plate 3 is flipped to keep it horizontal with the base frame 2, and the upper pressure plate 3 is engaged in the two buckles 13. Then, multiple handles 604 are swung to make the cam 603 press the positioning rod 602. The positioning rod 602 will slide vertically downward after being pressed and contact the circuit board. Then, the motor 17 is started and drives the gear 18 to mesh with the teeth 19, so that the irregular plate 15 slides at the bottom of the upper pressure plate 3 and can enter the positioning groove 16 during the sliding process. The positioning rod 602 is used to limit the circuit board and prevent it from resetting and affecting its fixation. The DC high voltage plug 501 and low voltage plug 12 are connected to the interface on the circuit board to perform testing on the circuit board. During the test, external water enters the front water inlet 401 through the water inlet valve 9 and the hose, and then enters the circuit board through the water inlet 401. The water flow path can be adjusted by setting the water inlet switching valve 403 so that the water outlet can be discharged through the rear water inlet 401 to the water outlet 402, and then discharged through the hose to the outlet valve 10.
