[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail.

[0027] This application discloses a clamping mechanism for testing electrical components.

[0028] A clamping mechanism for testing electrical components includes a processing table 1. Support parts 12 are provided on both sides of the processing table 1 to facilitate elbow support for the operator. A processing groove 11 is provided in the middle of the processing table 1. The processing table 1 is also symmetrically provided with clamping arms 2, which can clamp both ends of the circuit board so that the entire circuit board can be located in the processing groove 11.

[0029] The processing table 1 is equipped with a top abutting component 5, which can abut against the upper surface of the circuit board.

[0030] A lower abutment component 3 is slidably disposed inside the processing groove 11, and the lower abutment component 3 can abut against the lower surface of the circuit board.

[0031] There are two clamping arms 2, which have the same structure but different positions, and can clamp and flip both sides of the circuit board at the same time.

[0032] The clamping arm 2 includes a lifting groove 21, a lifting block 22, a clamping block 23, a mounting groove 25, a bearing 27, a mounting spring 26, a clamping slot 24, and a friction member 28. The lifting groove 21 is formed on the processing table 1. The lifting block 22 is slidably disposed within the lifting groove 21 and slides upward or downward. The mounting slot 25 is formed on the lifting block 22. Part of the clamping block 23 is located within the mounting slot 25. The bearing 27 is disposed on the clamping block 23 located within the mounting slot 25. Both ends of the mounting spring 26 are fixedly connected to the bearing 27 and the groove wall of the mounting slot 25, respectively. The clamping block 23 can slide relative to the clamping slot 24. This allows the clamping blocks 23 on the two clamping arms 2 to move closer to or further away from each other.

[0033] A clamping groove 24 is provided on the clamping block 23. When the two clamping blocks 23 are far apart, the circuit board can be easily placed between the two clamping blocks 23. Under the push of the mounting spring 26, the two clamping blocks 23 move closer to each other, so that the two ends of the circuit board can be locked into the clamping groove 24. Under the action of the bearing 27, the clamping block 23 can be easily rotated, thereby facilitating the flipping of the circuit board.

[0034] Friction component 28 is provided on lifting block 22 and is a friction component 28 that can keep lifting block 22 and processing table 1 stationary.

[0035] The friction component 28 includes a friction groove 281, a friction block 282, and a friction spring 283. The friction groove 281 is formed in the clamping block 23, the friction block 282 is slidably disposed in the friction groove 281, and the friction spring 283 is disposed between the friction block 282 and the side wall of the friction groove 281. The friction spring 283 has the tendency to force the friction block 282 to move towards the side wall of the lifting groove 21. The surface of the friction block 282 facing the lifting groove 21 is rough, which can increase the friction force and make the lifting block 282 stationary relative to the processing table 1 without the interference of external forces.

[0036] The lower abutment component 3 includes a lower abutment platform and a lifting adjustment component 4; the lower abutment platform is slidably disposed in the processing groove 11, and the lifting adjustment component 4 can be adjusted up and down to make the lower abutment platform stationary relative to the processing table 1.

[0037] The lower pressing platform 31 is hollow inside and has an upward-opening pressing hole 32. A lower pressing rod 33 is slidably mounted on the pressing hole 32, and an anti-detachment part 34 is fixedly mounted on the pressing rod. The anti-detachment part 34 is located inside the lower pressing platform 31 and has a cross-shaped structure. A pressing spring 35 is provided between the bottom of the anti-detachment part 34 and the bottom wall inside the lower pressing platform 31. The pressing spring 35 has a tendency to force the lower pressing rod 33 to move upward. When there is no external force, the pressing spring 35 can push the anti-detachment part 34, causing the anti-detachment part 34 to abut against the top wall inside the lower pressing platform 31. When the circuit board enters the processing tank 11, the top of the pressing rod 33 can abut against the lower surface of the circuit board, pressing the electrical components or the wires connecting the electrical components on the lower surface of the circuit board tightly, reducing the occurrence of detachment and thus improving the inspection effect.

[0038] The lower pressing platform has a pressing chamber containing a pressing airbag 36 and a fixed isolation plate 37. The isolation plate 37 is located between the pressing airbag 36 and the pressing spring 35. The pressing airbag 36 is located within the movement path of the anti-detachment part 34. Under the action of the pressing spring 35, the pressing rod can abut against electrical components at different heights on the lower surface of the circuit board. When the electrical component is too high, a greater abutting force is required. At this time, the anti-detachment part 34 will abut against the pressing airbag 36, and the pressing airbag 36, through its reaction force, can generate a greater reaction force on the pressing rod. Furthermore, when the pressing airbag 36 is compressed, other parts of the pressing airbag 36 will bulge, and the pressing airbag 36 will exert a pushing force on the anti-detachment parts 34 of other pressing rods, thereby improving the pressing effect of the pressing rods.

[0039] The lifting adjustment component 4 includes a relief groove 41, an ear plate 42, a lifting limit plate 43, a toothed groove 44, and a helical tooth 45. The relief groove 41 is opened at both ends of the processing table 1. The ear plate 42 is fixed at both ends of the lower pressing table 31, and the ear plate 42 is also located in the relief groove 41. The lower pressing table 31 can adjust the thrust of the pressing rod on the lower surface of the circuit board by moving up and down. As the lower pressing table 31 moves up and down, the ear plate 42 can also move up and down in the relief groove 41. The lifting limit plate 43 is rotatably located in the ear plate 42. The lifting limit plate 43 is also provided with a helical tooth 45. The relief groove 41 is provided with a toothed groove 44 that matches the helical tooth 45. When the helical tooth 45 is located in the toothed groove 44, the lower pressing table will not move down, so that the lower pressing table and the processing table 1 remain stationary. The lifting limit plate 43 also has a pressing part 46, which is exposed in the relief groove 41. Pushing the lower pressing part 46 can cause the lifting limit plate 43 to rotate, causing the helical teeth 45 of the lifting limit plate 43 to disengage from the tooth groove 44, thereby facilitating the lower pressing platform 31 to be raised and lowered for adjustment.

[0040] The top abutment assembly 5 includes a top pressure plate 51, an extension rod 52, a top pressure rod 53, and an elastic pressure ball 54. The top pressure plate 51 is rotatably mounted on the processing table 1, and a torsion spring is provided at the rotation point between the top pressure plate 51 and the processing table 1, which can force the top pressure plate 51 to move towards the processing groove 11. The extension rod 52 extends the length of the top pressure rod 53 and adds a connecting node, allowing the top pressure rod 53 to move more freely. The top pressure rod 53 and the extension rod 52 are connected by a ball joint, and the extension rod 52 and the top pressure rod 53 are also connected by a ball joint. This ball joint method allows the operator to easily control the position of the top pressure rod 53. The elastic pressure ball 54 is located at the end of the top pressure rod 53. Under the rotation of the top pressure plate 51 and the control of the operator, the elastic pressure ball 54 can press against the electrical component to be tested, so that the electrical component can be abutted and fixed, thereby facilitating testing.

[0041] The implementation principle of this embodiment is as follows: After the electrical components are installed on the circuit board, the electrical components on the circuit board need to be tested. First, push the clamping blocks 23 to move them away from each other. Then, snap the two sides of the circuit board into the mounting slot 25. Move the lifting block 22 downward so that the lower abutting component 3 can abut against the lower surface of the circuit board, and the top abutting component 5 can abut against one of the electrical components on the upper surface of the circuit board, facilitating the operator's testing. When it is necessary to flip the circuit board, simply move the lifting block 22 upward, then rotate the clamping block 23. After the circuit board is flipped, move it downward so that it enters the processing slot 11, allowing the operator to continue testing the electrical components on the circuit board or the wiring between the electrical components.

Therefore, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model.
