However, there are differences in size, and the existing pressing devices can only press and fix circuit boards of one size, with poor applicability. Moreover, when placing the circuit board, it may shift, affecting the product quality during subsequent processing. In view of the above problems, this application designs a pressing device for circuit board processing. Content of the 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 pressing device for circuit board processing, including a base 1. An adjusting mechanism for adjusting the circuit board is provided on the base 1. The adjusting mechanism includes a transverse groove 2. The transverse groove 2 is opened at the top of the base 1. Two first sliders 3 are slidably connected in the transverse groove 2. The two first sliders 3 are symmetrically distributed. A first motor 4 is installed on the right side of the base 1. The output end of the first motor 4 passes through the base 1 in the direction of the transverse groove 2 and is fixed with a bidirectional threaded rod 5 in the transverse groove 2. The first slider 3 is threadedly connected with the bidirectional threaded rod 5. An installation frame 6 is fixed at the top of the first slider 3. A cylinder 7 is installed at the top of the installation frame 6. The output end of the cylinder 7 passes through the installation frame 6 downward and is fixed with an upper pressing block 8. A lower pressing block 9 is fixed at the top of the first slider 3 directly below the upper pressing block 8. First sliding tracks 10 are fixed at the front and rear ends of the first slider 3. An intermediate block 11 is slidably connected in the first sliding track 10. The intermediate block 11 passes through the first sliding track 10 upward and is fixed with an adjusting block 12. A bottom block 13 is fixed at the bottom end of the intermediate block 11. A longitudinal groove 14 is opened at the top of the base 1. The longitudinal groove 14 is perpendicular to the transverse groove 2. Two second sliders 15 are slidably connected in the longitudinal groove 14. The two second sliders 15 are symmetrically distributed. Pneumatic telescopic components 16 are installed at the front and rear ends of the base 1. The output ends of the pneumatic telescopic components 16 pass through the base 1 in the direction of the second slider 15 and are fixed with it. A second sliding track 17 is fixed at the top of the second slider 15. The bottom block 13 is slidably connected in the second sliding track 17. Sliding grooves 18 are symmetrically opened in the adjusting block 12. Connecting rods 19 are slidably connected in the sliding grooves 18. The two connecting rods 19 pass through the adjusting block 12 toward the inner side and are fixed with contact blocks 20. Springs 21 are sleeved on the connecting rods 19. One end of the spring 21 is fixed on the adjusting block 12, and the other end of the spring 21 is fixed on the contact block 20.
[0023] When the device is in use, first, according to the size of the circuit board, the first motor 4 is started to drive the bidirectional threaded rod 5 to rotate, and the first slider 3 threadedly connected to the bidirectional threaded rod 5 moves along the transverse groove 2. At the same time, the first slider 3 drives the first sliding rail 10 to move, and the first sliding rail 10 drives the adjustment block 12, the middle block 11 and the bottom block 13 to move. The bottom block 13 moves along the second sliding rail 17 until the distance between the two first sliders 3 is adapted to the size of the circuit board. The circuit board is placed between the two first sliders 3 and above the lower pressing block 9. The two pneumatic telescopic components 16 are started, and their output ends drive the second slider 15 to move along the longitudinal groove 14. The second slider 15 drives the second sliding rail 17 to move. The second sliding rail 17 drives the bottom block 13, the middle block 11 and the adjustment block 12 to move along the first sliding rail 10 until the contact block 20 contacts the circuit board. The spring 21 is compressed, which plays a buffering role. Under the push of the contact block 20 on the circuit board, the circuit board remains horizontal and vertical. The cylinder 7 is started, and the output end of the cylinder 7 drives the upper pressing block 8 to move downward to contact the circuit board to complete the compression and fixation, ensuring the accuracy of subsequent processing.
[0024] During actual use, it was found that the second sliding rail 17 would deviate when moving, and the adjustment effect could not be achieved. In order to solve the above problem, in this embodiment, the top of the base 1 is located on both the left and right sides and the limiting mechanisms are fixed. The two limiting mechanisms are respectively located on the left and right sides of the second sliding rail 17. The limiting mechanism includes two fixed blocks 22. The two fixed blocks 22 are symmetrically fixed on the top of the base 1 front and back. A first limiting rod 23 is fixed between the two fixed blocks 22. The first limiting rod 23 passes through the second sliding rail 17, and the two second sliding rails 17 are slidably connected to the two first limiting rods 23.
[0025] During actual use, it was found that the middle block 11 would deviate and shake when driving the adjustment block 12 to move. In order to avoid the above problem, in this embodiment, two second limit rods 24 are symmetrically fixed in the first sliding track 10, and the second limit rods 24 pass through the middle block 11.
[0026] It is found in actual use that the circuit board may contact the mounting frame 6 and cause damage. In order to avoid the above problem, in this embodiment, a protective block 25 is fixed on the side wall of the mounting frame 6 close to the inner side.
[0027] In actual use, it was found that when the circuit board was pressed and fixed, the harder material would damage the circuit board. In order to avoid the above problem, in this embodiment, the surfaces of the upper pressing block 8, the lower pressing block 9 and the contact block 20 are all provided with anti-slip grooves, and the upper pressing block 8, the lower pressing block 9, the contact block 20 and the protective block 25 are all set to rubber material.
