[0023] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0024] Example:

[0025] like Figure 1-Figure 2As shown, a circuit board debonding machine anti-warping device is used to fix the circuit board and facilitate the cutting operation of the existing circuit board debonding machine cutting equipment, including a base 10, a support table 20, a pressing mechanism, and a moving mechanism. The support tables 20 include two, which are symmetrically arranged on the top of the base 10, and a cutting gap is provided between the two support tables 20; the pressing mechanism includes two, which are symmetrically arranged on the top of the two support tables 20, including a mounting frame 31, a pushing device and a pressing plate 33. The pushing device can be a cylinder 32, which is arranged on the mounting frame 31, and the pressing plate 33 is arranged at the bottom of the cylinder 32, which is used to press the circuit board toward the support table 20 and fix it; the opposite surfaces of the two pressing plates 33 are respectively aligned with the opposite surfaces of the two support tables 20; the moving mechanism is arranged between the support table 20 and the base 10, and is used to adjust the spacing between the support tables 20; wherein, the positions of the mounting frame 31 and the cylinder 32 do not interfere with the positions of the existing cutting equipment.

[0026] The working principle of the above technical solution is as follows:

[0027] When in use, the support table 20 can be first moved by the moving mechanism, and the gap between the two support tables 20 can be adjusted to change the cutting gap. The cutting gap is greater than the thickness of the cutting blade of the cutting equipment. In actual operation, the difference range can be 0.5mm-1mm. After adjustment, the circuit board to be cut is placed on the support table 20, and the cutting position is aligned with the cutting gap. The cylinder 32 drives the pressing plate 33 to press down and fix the circuit board. Since the opposite surfaces of the two pressing plates 33 are respectively aligned with the opposite surfaces of the two support tables 20, the pressing plate 33 and the support table 20 can both provide support and fixation near the cutting part, which is not easy to cause warping of the circuit board.

[0028] In another embodiment, if Figure 1-2 As shown, the moving mechanism includes a first support seat 41, a second support seat 42 and a bidirectional screw rod 43. The first support seats 41 are respectively arranged on both sides of the top of the base 10, and both ends of the bidirectional screw rod 43 are rotatably connected to the first support seats 41. The second support seats 42 are respectively arranged at the bottom of the two support platforms 20 between the first support seats 41. The middle parts of the two second support seats 42 are respectively provided with screw holes with opposite rotation directions and matching the threaded parts of the bidirectional screw rod 43. The second support seats 42 are respectively sleeved on the outside of the bidirectional screw rod 43 through the screw holes; movable support members are respectively provided on both sides of the base 10 adjacent to the position of the first support seat 41, and the movable support members include a slider 51 arranged at the bottom of the support platform 20 and a slide rail 52 arranged at the top of the base 10.

[0029] When adjusting the positions of the two support platforms 20, the bidirectional screw rod 43 can be directly rotated to drive the two support platforms 20 to move toward or away from each other through the second support seat 42, so as to facilitate the adjustment of the cutting gap. The slider 51 and the slide rail 52 play the role of facilitating movement and support.

[0030] In another embodiment, if Figure 1-2 As shown, one end of the bidirectional screw rod 43 extends to the outside between the support platform 20 and the base 10 , and optionally, a handle 44 is provided at the end or a motor is connected to facilitate the rotation of the bidirectional screw rod 43 .

[0031] In another embodiment, a rubber pad is provided at the bottom of the pressing plate 33. The rubber pad at the bottom of the pressing plate 33 is not easy to damage the circuit board when pressing down.

[0032] In another embodiment, if Figure 2 As shown, a retaining edge 21 parallel to the moving direction of the moving mechanism is provided on the top of the support platform 20; a plurality of rows of limiting holes 22 matching the widths of circuit boards of different specifications are provided on the top of the support platform 20, and a detachable limiting column 23 is provided in the limiting hole 22. The retaining edge 21 and the limiting column 23 are conducive to confirming the placement position of the circuit board and conveniently and quickly fixing the circuit board, wherein the limiting column 23 can be moved to different limiting holes 22 according to circuit boards of different specifications.

[0033] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
