Technical Field
[0001] The utility model relates to the field of detection jigs, in particular to a PCB electronic board detection jig. Background Art
[0002] PCB (Printed Circuit Board), also known as printed circuit board, is the support body of electronic components and the carrier of electrical connection of electronic components. It plays a vital role in electronic equipment. The quality and reliability of PCB directly affect the overall performance and life of electronic equipment. Using high-quality PCB materials, strict manufacturing processes and reasonable design can improve the reliability of PCB and reduce the failure rate of equipment.
[0003] PCB electronic board inspection fixtures are important tools for testing the quality and performance of PCB electronic boards. They play a key role in the PCB production process, ensuring that the produced PCBs meet design requirements and quality standards. An existing PCB electronic board inspection fixture uses cameras, image processors, and other equipment to capture and analyze the PCB electronic board surface, automatically identifying and determining defects. This method has high detection efficiency and good accuracy, which can greatly improve the reliability and stability of detection.
[0004] An existing PCB inspection jig uses cameras, image processors, and other equipment to capture and analyze the surface of PCBs for inspection purposes. However, when turning the PCB over, inspectors must manually flip it over. This increases the inspector's workload and the frequency of hand contact with the PCB surface, which can easily cause scratches, stains, and even oxidation, affecting the quality of the PCB.

[0028] The following will describe the embodiments according to the overall structure of the present utility model.
[0029] A PCB electronic board detection fixture, as Figure 1 - Figure 4 shown, includes a detection fixture main body 1. A fixed seat 2 is fixedly installed at the end of the detection fixture main body 1. A rotating disk 3 is rotatably installed at one end of the fixed seat 2 close to the detection fixture main body 1. A rotating shaft 4 is fixedly connected inside the rotating disk 3. A placement frame 5 is fixedly installed at the end of the rotating shaft 4. First sliding rods 6 and second sliding rods 7 which are symmetrically arranged are slidably installed inside the rotating disk 3. A first support plate 61 is fixedly installed at the end of the first sliding rod 6. A second support plate 71 is fixedly installed at the end of the second sliding rod 7. Pulley 9 is fixedly installed on the outer wall at the ends of the first sliding rod 6 and the second sliding rod 7. A spring 10 fixedly connected to the rotating disk 3 is fixedly installed at the end of the pulley 9. A cam 8 is fixedly installed on the inner wall of the fixed seat 2. A limiting groove 81 is opened on the outer wall at the end of the cam 8. A crank 11 is fixedly installed at the other end of the rotating shaft 4. When one side surface of the PCB electronic board is detected, only by manually rotating the crank 11, the reverse side detection of the PCB electronic board can be realized. In this way, not only can the work efficiency be improved, the work intensity of the detection personnel be reduced, but also the number of contacts between the hands of the detection personnel and the PCB electronic board can be reduced, avoiding scratches and stains on the surface of the PCB electronic board during the reverse side process, thereby reducing the defective rate and achieving the purpose of effectively reducing costs.
[0030] Please refer to Figure 1 - Figure 3 , the placement frame 5 is designed in a "C" shape, and the placement frame 5 is located at the middle position of the detection fixture main body 1, so that the PCB electronic board can be easily placed into the placement frame 5 for detection and the PCB electronic board can be limited.
[0031] Please refer to Figure 3 and Figure 4 , the cross-section of the first sliding rod 6 is designed in a rectangle, and the second sliding rod 7 is arranged corresponding to the first sliding rod 6, so that the first sliding rod 6 and the second sliding rod 7 can slide inside the rotating disk 3, thereby realizing the support of the PCB electronic board.
[0032] Please refer to Figure 1 - Figure 3, the first pallet 61 is designed in a "C" shape, and one outer wall of the first pallet 61 is fitted with one outer wall of the placement frame 5, and the widths of both sides of the first pallet 61 are greater than the widths of both sides of the placement frame 5. The second pallet 71 is arranged corresponding to the first pallet 61, so that the first pallet 61 and the second pallet 71 can hold the PCB electronic board placed in the placement frame 5 and switch with each other when turning over.
[0033] Please refer to Figure 2 - Figure 4 , the rotating disk 3 is designed in a cylindrical shape, and a through groove for the first sliding rod 6 and the second sliding rod 7 to slide is opened in the rotating disk 3, so that the first sliding rod 6 and the second sliding rod 7 can be driven to slide when the rotating disk 3 rotates.
[0034] Please refer to Figure 1 - Figure 4 , one end of the cam 8 in contact with the pulley 9 is designed in an inclined surface, and a through hole for the rotating shaft 4 to penetrate is opened in the cam 8, so that when turning over the PCB electronic board, the pulley 9 will move closely along the inclined surface of the cam 8 under the action of the spring 10, thereby realizing the conversion of the first pallet 61 and the second pallet 71.
[0035] Please refer to Figure 2 - Figure 4 , the cross section of the limiting groove 81 is designed in a trapezoid shape, and two groups of limiting grooves 81 are symmetrically arranged at one inclined surface end of the cam 8. After the rotating disk 3 rotates 180°, the pulley 9 will enter the limiting groove 81, and the limiting groove 81 will play a certain limiting role on the pulley 9, so that the whole device stops flipping.
[0036] The working principle of the present utility model is as follows: when detecting the surface of the PCB electronic board, first place the PCB electronic board in the placement frame 5, and then start the detection fixture main body 1 to detect the upward side of the PCB electronic board. At this time, the first pallet 61 is at one end of the surface of the detection fixture main body 1 far from the PCB electronic board, and the second pallet 71 is located below the detection fixture main body 1 to completely hold the PCB electronic board. When it is necessary to turn over after the detection is completed, manually rotate the crank 11 by 180°, the rotating shaft 4 will simultaneously drive the rotating disk 3 to rotate, and then drive the first sliding rod 6, the first pallet 61, the second sliding rod 7 and the second pallet 71 to also rotate by 180°. During this process, under the action of the spring 10, the pulley 9 will move closely along the inclined surface of the cam 8, thereby realizing the opposite sliding of the first sliding rod 6 and the second sliding rod 7, and simultaneously driving the first pallet 61 and the second pallet 71 to move in opposite directions. As the second pallet 71 gradually moves away from the surface of the PCB electronic board, the first pallet 61 gradually holds the PCB electronic board. When the pulley 9 slides into the limiting groove 81, the rotation stops, and at this time, the operation of turning over the PCB electronic board is completed.
