[0002] A multi-layer circuit board pressing device is a device used for pressing and processing multi-layer circuit boards. It is widely used in the production and processing of multi-layer circuit boards. As the demand for the use of multi-layer circuit board pressing devices gradually increases, the existing multi-layer circuit board pressing devices can no longer meet people's needs. Therefore, a more convenient multi-layer circuit board pressing device is needed.

[0003] When multi-layer PCB circuit boards are produced, the PCB circuit boards are usually first arranged, stacked and fixed, and then moved to the pressing processing position for pressing. A certain amount of time is wasted during the movement, which reduces the processing efficiency of the PCB circuit boards and cannot meet the use needs of the enterprise. At the same time, the pressed circuit boards will adhere to the pressing plate or base, making it difficult to remove them. Summary of the invention

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0023] A circuit board pressing device, comprising a machine platform 1:

[0024] A frame 2 is arranged above the machine platform 1, wherein a hydraulic rod 3 is arranged on the frame 2, and a pressing plate 5 is arranged on the output shaft of the hydraulic rod 3;

[0025] The top of the machine 1 is also provided with a rectangular groove 6 corresponding to the pressing plate 5, wherein a groove 7 is provided in the middle of the bottom of the rectangular groove 6, and a top plate 8 driven by an electric push rod 22 is provided in the groove 7, and a plurality of circles of receiving grooves 9 are arranged around the bottom wall of the rectangular groove 6 outside the groove 7, wherein a plurality of groups of strip grooves 10 connecting the receiving grooves 9 and the groove 7 are radially provided on the bottom wall of the rectangular groove 6, and a rectangular notch 11 corresponding to the strip groove 10 is provided at the top edge of the top plate 8, and a connecting rod 12 is provided in the notch 11 and the strip groove 10, wherein the end of the connecting rod 12 is connected to the inner wall of a rectangular frame 13 located in one group of the receiving grooves 9;

[0026] The rectangular grooves 6 outside the accommodating grooves 9 are each provided with a vertical plate 14 parallel to the corresponding side walls, wherein screws 15 are correspondingly provided between the back sides of the vertical plates 14 and the side walls of the rectangular grooves 6, and the corresponding two groups of screws 15 are connected by screw tubes 16, and a measuring ruler 17 is also provided on the back side of the vertical plate 14 extending to the top of the machine 1 outside the rectangular grooves 6.

[0027] In this embodiment, a mounting plate 4 is arranged at the bottom of the output shaft of the hydraulic rod 3 , wherein the diameter of the mounting plate 4 is smaller than the diameter of the pressing plate 5 , and bolts for locking and fixing the pressing plate 5 are arranged on the mounting plate 4 .

[0028] like Figure 1 As shown, the four groups of top corner areas at the bottom of the rectangular groove 6 are all provided with a drop opening 18, wherein a discharge pipe 19 corresponding to the drop opening 18 is provided in the machine 1, and a collection bucket 20 is screwed on the discharge pipe 19.

[0029] like Figure 1 As shown, an arc-shaped guide portion 21 is folded outward at the top end of the vertical plate 14 .

[0030] In this embodiment, the top of the rectangular frame 13 and the top of the connecting rod 12 are both arranged flush with the inner bottom wall of the rectangular groove 6, wherein a magnetic connecting block located in the notch 11 is arranged at the bottom of the end of the connecting rod 12, and the bottom end of the strip groove 10 is higher than the horizontal plane of the bottom end of the accommodating groove 9.

[0031] The working principle of the present invention is as follows: the positions of the four groups of vertical plates 14 are adjusted according to the diameter of the laminated circuit board, so that the size of the rectangle formed by the four groups of vertical plates 14 is adapted to the size of the required processed circuit board. The specific steps are to rotate the screw tube 16 to expand or reduce the spacing between the two groups of screw rods 15 inside it, and then adjust the position of the vertical plate 14. At this time, the adjustment range of the position of the vertical plate 14 can be clearly known through the measuring ruler 17, and finally the size of the rectangle formed by the four groups of vertical plates 14 is adapted to the size of the circuit board. At the same time, a rectangular frame 13 with a smaller diameter than the rectangular opening formed by the four groups of vertical plates 14 is placed, and the rectangular frame 13 is placed in the receiving groove 9 of the corresponding size, wherein the rectangular frame 13 also drives the connecting rod 12 to be embedded in the strip groove 10, and the end thereof is inserted into the notch 11 and fixed by magnetic connection through the magnetic connection block. At the same time, a pressing plate 5 of corresponding specifications is installed on the mounting plate 4;

[0032] When in use, the circuit board is stacked in the rectangular groove 6 between the four groups of vertical plates 14 for fixing to prevent it from horizontal movement during the subsequent pressing process and affecting the processing work. Then the hydraulic rod 3 drives the pressing plate 5 to move downward to squeeze and press the circuit board. When the pressed circuit board needs to be taken out, the electric push rod 22 drives the top plate 8 to slide upward from the groove 7, and then pushes the circuit board out from the gap between the four groups of vertical plates 14, so that the circuit board is separated from the bottom wall of the rectangular groove 6 for easy removal. In the above process, the top plate 8 will resist the connecting rod 12 through the notch 11, and then push the rectangular frame 13 out of the accommodating groove 9, so that the top plate 8 will lift the middle of the bottom of the circuit board in the process of lifting the top plate 8. The connecting rod 12 and the rectangular frame 13 will also lift and separate the edge of the circuit board, and expand the contact area with the bottom of the circuit board through multi-point support, so that it is easy to quickly separate from the bottom of the rectangular groove 6, thereby achieving the purpose of facilitating its removal.

[0033] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
