Detailed Description of the Preferred Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, a calibration mechanism for processing circuit boards, comprising a base 1, a support base 2, a clamping mechanism 3, a clamping assembly 9 and a limiting mechanism 14. The support base 2 is arranged on the top of the base 1, and there are multiple support bases 2. The clamping mechanism 3 includes a slideway 4, a sliding block 5, a threaded rod 6, a motor 7 and a fixed block 8. The slideway 4 is opened on the top of the base 1, the sliding block 5 is arranged in the slideway 4, the motor 7 is arranged on the side of the base 1, the output end of the motor 7 is connected to one end of the threaded rod 6, the threaded rod 6 is located in the slideway 4, the other end of the threaded rod 6 is threadedly connected to the sliding block 5, the bottom of the fixed block 8 is connected to the top of the sliding block 5. There are two clamping mechanisms 3, and the clamping mechanism 3 is connected to the fixed block 8 through the limiting mechanism 14. The clamping assembly 9 includes a clamping frame 10, a bolt 11, a bearing 12 and a clamping plate 13. One end of the bolt 11 passes through the clamping frame 10 and is connected to one end of the bearing 12, and the other end of the bearing 12 is connected to the clamping plate 13. The limiting mechanism 14 includes a chute 15, a slider 16, a telescopic rod 17, an iron block 18 and an electromagnet 19. The chute 15 is opened on the fixed block 8, one end of the slider 16 is slidably connected to the chute 15, the other end of the slider 16 extends into the clamping frame 10, one end of the telescopic rod 17 is connected to the slider 16, the other end of the telescopic rod 17 is connected to one end of the iron block 18, the other end of the iron block 18 extends into the clamping frame 10, one end of the electromagnet 19 is connected to the clamping frame 10, and the other end of the electromagnet 19 adsorbs the iron block 18. There are two clamping assemblies 9 and two limiting mechanisms 14. A position sensor 21 is arranged at the bottom of the fixed block 8, and a control screen 20 is arranged on the front of the base 1. The position sensor 21 is electrically connected to the control screen 20.

[0023] During use, first place the device in a designated position. Then, the device can be supported by the support base 2 at the bottom of the base 1. Next, place the circuit board that needs to be clamped by the clamping plate 13 between the two clamping mechanisms 3. The position of the circuit board is at the center of the clamping frame 10. Then, start the motor 7 to drive the threaded rod 6 to rotate. As a result, the sliding block 5 will drive the clamping frame 10 on the fixed block 8 to rotate. After the clamping frame 10 moves to a certain position, it will contact the bottom of the circuit board. Place the circuit board on the clamping frame 10. Through the position sensor 21 at the bottom of the fixed block 8, the moving distance can be transmitted to the control screen 20. When the position sensor 21 moves to a suitable position, it will transmit the data to the control screen 20. For different circuit boards, the moving distances of the slider 16 are different. The data transmitted to the control screen 20 is compared with the calibration data. After the data is consistent, stop moving the sliding block 5 to avoid excessive movement and excessive clamping force on the circuit board, which may cause damage to the circuit board. Then, turn the bolt 11 to lower the clamping plate 13 connected to the bolt 11 through the bearing 12 to clamp the circuit board, and the limit can be completed. Then, the circuit board can be processed. Finally, separate the circuit board from the device. When processing circuit boards of different shapes, different models of clamping components 9 need to be replaced. First, turn off the electromagnet 19 to separate the electromagnet 19 from the iron block 18. Then, pull the telescopic rod 17 to separate the iron block 18 from the clamping frame 10. Then, push the slider 16 on the sliding groove 15 to separate the slider 16 from the clamping frame 10. Then, the clamping frame 10 can be separated from the fixed block 8, and a new clamping component 9 can be replaced. The rotation speed of the above-mentioned motor 7 is consistent, and there will be no situation of inconsistent rotation speed. The clamping mechanism 3 is a conventional technology in the market and will not be described in detail here. The dimensions of all components in this structure are not specifically limited and need to be produced according to the actual situation. The position sensor 21 in the text is a conventional technology in the market. Those skilled in the art clearly know the various components and working principles included inside, and will not be described in detail here.

[0024] The above-mentioned motor 7 is not convenient to operate. To solve this problem, in this embodiment, the control screen 20 is electrically connected to the motor 7.

[0025] To improve stability, in this embodiment, the two clamping mechanisms 3 are symmetrically arranged, the two clamping components 9 are symmetrically arranged, and the two limiting mechanisms 14 are symmetrically arranged.

[0026] When the above-mentioned clamping frame 10 and the clamping plate 13 clamp the circuit board, the circuit board is easily damaged by knocking. To solve this problem, in this embodiment, rubber pads are provided inside the clamping frame 10 and at the bottom of the clamping plate 13.

[0027] To improve the connection effect, in this embodiment, the fixed block 8 is fixedly connected to the sliding block 5.

[0028] The stability of the above-mentioned support base 2 is relatively poor. To solve this problem, in this embodiment, several of the support bases 2 are symmetrically arranged.
