[0002] Circuit boards, also known as printed circuit boards, are a common component in electronic devices, used to connect electronic components and implement circuit functions. They miniaturize and visualize circuits, playing a vital role in the mass production of fixed circuits and optimizing the layout of electrical appliances. During the circuit board manufacturing process, performance testing is often required, necessitating a testing machine. Numerous types of testing machines are suitable for circuit board testing, and circuit board testers are one such example. Under computer control, circuit board testers automatically perform stimulation, measurement, data processing, and display or output test results. They are widely used due to their high speed, high precision, multi-function, multi-parameter capabilities, and wide measurement range.

[0003] Existing circuit board inspection machines usually use positioning fixtures to position circuit boards to prevent excessive displacement of circuit boards during inspection. Since the positioning fixtures usually position the circuit boards rigidly and lack adjustment flexibility, they are prone to causing damage to the circuit boards. The anti-damage effect of circuit board inspection machines needs to be improved. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a detection machine that can prevent circuit boards from being pinched and damaged. It solves the problem that existing circuit board detection machines usually use positioning fixtures to position the circuit boards in order to prevent excessive displacement of the circuit boards when detecting the circuit boards. Since the positioning fixtures usually position the circuit boards in a rigid manner and do not have adjustable elasticity, they are prone to pinching and damage to the circuit boards. The anti-pinch damage effect of the circuit board detection machine needs to be improved.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detection machine that can prevent circuit boards from being damaged by clamping, comprising a circuit board tester and a circuit board, the circuit board tester comprising a workbench, a body being arranged on the top of the workbench, a detection mechanism being arranged on the body, a detection platform being arranged in the body, a fixed block being arranged on the top of the detection platform, an adjusting rod being arranged on one side of the fixed block, a splint being arranged on one end of the adjusting rod, a silicone pad being arranged on one side of the splint, a spring being sleeved on the adjusting rod, an adjusting groove being arranged on one side of the fixed block, limiting grooves being arranged on both sides of the inner wall of the adjusting groove, a limiting block being arranged on one side of the adjusting rod, a display screen being arranged on one side of the body, and a control button being arranged on the body.

[0006] As a preferred technical solution of the present invention, the bottom end of the fixing block is fixedly installed at the center position of the top end of the testing platform, and the fixing block, adjustment rod, clamping plate and limit block are all made of hard materials.

[0007] As a preferred technical solution of the present invention, the adjustment slot is adapted to the adjustment rod, and one end of the adjustment rod extends into the adjustment slot.

[0008] As a preferred technical solution of the present invention, there is a certain space between the inserted end of the adjusting rod and the bottom of the adjusting slot, and limit blocks are fixedly installed on both sides of the inserted end of the adjusting rod.

[0009] As a preferred technical solution of the present invention, the two groups of limit grooves are respectively matched with the two groups of limit blocks, and the two groups of limit blocks are respectively slidably installed in the two groups of limit grooves.

[0010] As a preferred technical solution of the present invention, the center position of one side of the splint is fixedly mounted on the protruding end of the adjusting rod, the inner diameter of the spring is slightly larger than the diameter of the adjusting rod, and the spring is sleeved on the adjusting rod.

[0011] As a preferred technical solution of the present invention, one end of the spring is in contact with one side of the fixed block, the other end of the spring is in contact with one side of the splint, the silicone pad is fixedly installed on the other side of the splint, the bottom of the splint is in contact with the top of the testing platform, there are two groups of splints and the installation structures of the two groups of splints are the same, the circuit board is placed on the top of the testing platform and the circuit board is located between the two groups of splints.

[0012] Compared with the prior art, the present invention provides a detection machine that can prevent circuit board damage due to pinching, and has the following beneficial effects:

[0013] The present invention relates to a detection machine capable of preventing circuit boards from being damaged by being clamped. The circuit board is placed between two sets of clamping plates by arranging a fixed block, an adjusting rod, a clamping plate, a silicone pad, a spring, an adjusting slot, a limiting slot, and a limiting block. The two sets of clamping plates squeeze the corresponding springs and drive the adjusting rod to move toward the fixed block. Due to the rebound effect of the spring, the two sets of clamping plates will be tightly attached to the two ends of the circuit board. Since the spring combined with the adjusting rod is elastically adjusted, the position of the clamping plate will change with the force generated by the squeezing of the two ends of the circuit board, which is not easy to cause clamping damage to the circuit board. The silicone pad can make the clamping plate closer to the circuit board and further prevent the circuit board from being clamped by the clamping plate. The positioning structure of the detection machine can be elastically adjusted, is not easy to cause clamping damage to the circuit board, and can further improve the anti-clamping damage effect of the circuit board detection machine.
