[0002] Automotive circuit boards are printed circuit boards (PCBs) specifically designed for automotive electronic systems. They play a crucial role in these systems, housing functional modules such as the engine control unit (ECU), in-vehicle entertainment system, and driver assistance system, ensuring the normal operation of automotive electronic devices. During the production process, circuit boards need to be tested using testing equipment to determine their qualification. During circuit board testing, clamping equipment is required to hold and fix the circuit boards in place.

However, there are gaps between the positioning pins and the positioning holes on the circuit board. The test points and contacts are small, and even a slight misalignment can easily cause the contacts and test points to misalign, resulting in test failure. Furthermore, the circuit boards are inconvenient to remove after testing, which reduces work efficiency.

[0004] Based on this, a clamping device for testing automotive circuit boards that is easy to fix is ​​now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, a clamping device for testing automotive circuit boards that is easy to fix includes a base 1. The top of the base 1 has a placement groove 2. A positioning post 3 is fixedly connected inside the placement groove 2. Limiting rods 4 are fixedly installed at the four corners of the top of the base 1. Lifting plates 5 are slidably installed on the outside of the four limiting rods 4. A base plate 9 is fixedly installed at the bottom of the base 1 by screws.

[0027] The base 1 is provided with a clamping mechanism 6 inside, and a feeding mechanism 8 is provided symmetrically on the top of the base 1.

[0028] In this embodiment, the automotive circuit board to be tested is positioned and placed inside the placement slot 2 by the positioning post 3. The circuit board is pressed down to compress the spring 82, and then the circuit board is clamped and fixed by the clamping mechanism 6. The top of the lifting plate 5 is connected to the pressing device. When the pressing device works, it drives the lifting plate 5 to move downward, and the contact point 12 contacts the test point on the circuit board, thereby testing the circuit board.

[0029] In one embodiment, such as Figure 2 and Figure 3As shown, the clamping mechanism 6 includes a gear 61, which is rotatably mounted on the top inside the base 1. The gear 61 is symmetrically meshed with racks 62 on its exterior. A movable component 65 is fixedly mounted on one end of each rack 62. A driving assembly is provided on one side of one of the racks 62. The driving assembly includes a fixing component 63, which is fixedly mounted on one side of one of the racks 62. A hydraulic cylinder 64 is fixedly mounted on one side of the fixing component 63, and the hydraulic cylinder 64 is fixedly mounted to the base 1. Two sliding grooves 7 are provided on the top of the base 1. The movable part 65 is slidably installed on the base 1 through the sliding grooves 7. The top of the movable part 65 is rotatably mounted with a guide wheel 66. When the circuit board needs to be clamped, the hydraulic cylinder 64 retracts to drive the fixed part 63 to move. Due to the cooperation of the gear 61, the two racks 62 move together, and the two movable parts 65 move closer to each other, so that the guide wheel 66 contacts the circuit board, effectively clamping the circuit board. After the test is completed, the hydraulic cylinder 64 extends. Similarly, the two movable parts 65 move to one end, and the clamping of the circuit board is released.

[0030] In one embodiment, such as Figure 1 and Figure 4 As shown, the top of the base 1 is symmetrically provided with mounting slots 81. The unloading mechanism 8 includes multiple springs 82, which are equidistantly fixed inside the mounting slots 81. Unloading plates 83 are fixedly installed on the top of the multiple springs 82, and the unloading plates 83 are slidably installed between the mounting slots 81 and the base 1. After the circuit board is placed into the placement slot 2 through the positioning pins 3, the circuit board is pressed down, and the unloading plates 83 move into the mounting slots 81. The springs 82 are compressed, and the bottom of the circuit board contacts the bottom of the placement slot 2. The circuit board is clamped by the clamping mechanism 6. After the test is completed, the clamping mechanism 6 releases the clamp on the circuit board. Due to the reset effect of the springs 82, the unloading plates 83 move upward to lift the circuit board, which facilitates the unloading process of the circuit board and improves the testing efficiency of the circuit board.

[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, a connection port 10 is embedded in one side of the lifting plate 5, and a test plate 11 is fixedly installed at the bottom of the lifting plate 5. A contact 12 is installed at the bottom of the test plate 11, and the contact 12 is electrically connected to the connection port 10. The lifting plate 5 is connected to the test equipment through the connection port 10 and wires. The contact 12 contacts the test points of the circuit board. By measuring the current, voltage, resistance and other values ​​between each contact 12, the circuit board is judged to be qualified.

[0032] The above embodiment discloses a clamping device for testing automotive circuit boards that facilitates fixation. After the circuit board is placed into the placement groove 2 via the positioning pin 3, the circuit board is pressed down, causing the feeding plate 83 to move into the mounting groove 81. The spring 82 compresses, bringing the bottom of the circuit board into contact with the bottom of the placement groove 2. The hydraulic cylinder 64 retracts, causing the fixing member 63 to move. Due to the engagement of the gear 61, the two racks 62 move together, and the two moving parts 65 move closer together, bringing the guide wheel 66 into contact with the circuit board, effectively clamping the circuit board. The top of the lifting plate 5 is connected to the pressing device, which operates... The lifting plate 5 moves downward, and the contact 12 contacts the test point on the circuit board. The lifting plate 5 is connected to the test equipment through the connection port 10 and the wire. The contact 12 contacts the test point on the circuit board. By measuring the current, voltage, resistance and other values ​​between each contact 12, the circuit board is judged to be qualified. After the test is completed, the lifting plate 5 moves upward, the hydraulic cylinder 64 extends, and the two moving parts 65 move to one end. The clamping of the circuit board is released. Due to the reset action of the spring 82, the unloading plate 83 moves upward to lift the circuit board, which facilitates the unloading of the circuit board and improves the testing efficiency of the circuit board.
