[0001] This utility model relates to the field of circuit board testing technology, specifically a circuit board bending strength testing device. Background Technology

[0002] Circuit boards are a crucial component of modern electronic devices, and their quality directly impacts the performance and reliability of these devices. During circuit board production, numerous tests are required to ensure quality, including electrical performance testing and visual inspection. However, current technology lacks specialized equipment for testing the bending strength of circuit boards. Generally, bending strength is observed by manually bending the board, which not only poses safety hazards but also lacks a standardized testing method.

[0003] In view of this, in order to solve the above problems, this utility model proposes a circuit board bending strength testing device, which aims to provide a device that can accurately and quickly test the bending strength of circuit boards, thereby ensuring that the quality of circuit boards meets relevant standards. This application was developed in this context. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model discloses a circuit board bending strength testing device, comprising:

[0028] Base 1;

[0029] The fixing clamp 2 is fixed to one end of the surface of the base 1 to limit one side of the circuit board 8;

[0030] Movable clamp 4 is movably set at the other end of the surface of base 1 to limit the other side of circuit board 8;

[0031] Mounting plate 3 is used to mount movable clamp 4, and the length direction of mounting plate 3 points towards fixed clamp 2;

[0032] The bending drive mechanism 5 is connected between the mounting plate 3 and the base 1, and is used to drive the end of the mounting plate 3 away from the fixed clamp 2 to make an arc motion around the fixed clamp 2.

[0033] With the above structure, when in use, the two sides of the circuit board 8 are first limited by the fixed clamp 2 and the movable clamp 4. Then, the bending drive mechanism 5 drives the mounting plate 3 to make an arc motion away from the fixed clamp 2, so that the movable clamp 4 moves and bends the circuit board 8. During the bending process, the breakage of the circuit board 8 can be observed with the naked eye, thereby realizing the rapid detection of the bending strength of the circuit board.

[0034] The guide structure 6 is an arc-shaped guide groove embedded in the surface of the base 1. An arc-shaped guide block 13 is fixed at the bottom of the mounting plate 3. The arc-shaped guide block 13 is slidably connected to the arc-shaped guide groove. In order to facilitate observation of the bending degree of the circuit board 8, the arc-shaped guide groove is provided with a scale 11.

[0035] The bending drive mechanism 5 is an electric telescopic rod. One end of the electric telescopic rod is rotatably connected to the base 1, and the other end of the electric telescopic rod is rotatably connected to the end of the mounting plate 3 away from the fixed clamp 2. In use, the extension and retraction of the electric telescopic rod drives the mounting plate 3 to make arc movements, which is convenient and labor-saving. The base 1 is fixedly installed with a PLC controller 7, which is connected to the electric telescopic rod for signal control of the extension and retraction of the electric telescopic rod, making operation convenient.

[0036] The fixing fixture 2 includes a first fixing seat 21 fixed on the base 1. Two first limiting plates 22 are slidably provided at both ends of the surface of the first fixing seat 21, and a first bidirectional threaded rod 23 is rotatably mounted on the first fixing seat 21. The two ends of the first bidirectional threaded rod 23 are respectively threaded to the two first limiting plates 22. A first baffle 24 is fixed on the surface of the first fixing seat 21. When the first bidirectional threaded rod 23 rotates, it can drive the two first limiting plates 22 to move closer or further apart, thereby facilitating the adjustment of the distance between the two first limiting plates 22 according to the thickness of the circuit board 8. The function of the first baffle 24 is to block the end of the circuit board 8. It can be understood that during use, the first limiting plates 22 do not need to be bent to clamp the circuit board 8, but only need to limit the end of the circuit board 8 between the two first limiting plates 22.

[0037] Furthermore, the movable clamp 4 is slidably mounted on the mounting plate 3 along its length, allowing the distance between the fixed clamp 2 and the movable clamp 4 to be adjusted according to the length of the circuit board 8.

[0038] The surface of the mounting plate 3 is fixed with a slide rail 10. The movable clamp 4 includes a second fixed seat 41 that is slidably installed in the slide rail 10. Two second limiting plates 42 are slidably provided at both ends of the surface of the second fixed seat 41. A second bidirectional threaded rod 43 is rotatably installed on the second fixed seat 41. The two ends of the second bidirectional threaded rod 43 are respectively threaded to the two second limiting plates 42. A second baffle 44 is fixed on the surface of the second fixed seat 41. In use, by moving the second fixed seat 41 in the slide rail 10, the distance between the movable clamp 4 and the fixed clamp 2 can be adjusted, thereby limiting circuit boards 8 of different lengths. When it is necessary to limit the side of the circuit board 8, the principle is similar to that of the fixed clamp 2. First, the side of the circuit board 8 is inserted between the second limiting plates 42. Then, the second bidirectional threaded rod 43 is rotated to drive the two second limiting plates 42 to move closer to each other and limit the side of the circuit board 8.

[0039] In some embodiments, a screw 12 is rotatably provided inside the slide rail 10. The screw 12 is threadedly connected to the second fixed seat 41. By rotating the screw 12, the second fixed seat 41 can be moved within the slide rail 10, thereby facilitating the adjustment of the position of the movable clamp 4 on the mounting plate 3.

[0040] In some embodiments, a protective cover 9 is fixedly installed on the base 1. The protective cover 9 has a door that can be rotated. The protective cover 9 is a transparent structure. When in use, the door is first opened to limit the circuit board 8, and then the door is closed. The operation can be performed through the PLC controller 7 from outside the protective cover 9, which improves the safety during testing.

[0041] In summary, when using this invention, firstly, the position of the movable clamp 4 on the mounting plate 3 is adjusted according to the length of the circuit board 8. Then, the circuit board 8 is securely fixed on the base 1 using the fixed clamp 2 and the movable clamp 4. Subsequently, the electric telescopic rod 5 acts as a bending drive mechanism, driving the mounting plate 3 to move the movable clamp 4 in an arc around the fixed clamp 2, thereby achieving the bending test of the circuit board 8. During the bending process, the arc-shaped guide groove and its scale 11 help to visually observe the degree of bending of the circuit board 8. The PLC controller 7 is connected to the electric telescopic rod, enabling precise control of the bending process. The entire testing process is carried out inside the transparent protective cover 9, ensuring operational safety and facilitating observation of changes in the circuit board 8.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
