the top surface of the placing table 41 is fixedly connected with a first mounting frame 46, the bottom surface of the first mounting frame 46 is fixedly connected with a third telescopic rod 47, the telescopic end of the third telescopic rod 47 points to the placing table 41, and a rolling component used for moving the substrate is fixedly connected with the third telescopic rod 47.

In the embodiment, the first conveyor belt conveys the substrate into the placing table, the second telescopic rod on the placing table drives the second push plate to push the substrate into the pressing box body, after pressing is completed, the finished circuit board is pushed out by the first push plate, and the second conveyor belt conveys the finished circuit board out of the placing table; in the process of carrying in and out, the positions of the substrates are not always right opposite to the inlet of the pressing box body, so that the substrates need to be moved by the rolling assembly on the placing table in a small range.

As shown in fig. 8, the rolling assembly includes a second mounting bracket 48 fixedly connected to the telescopic end of the third telescopic rod 47, a first rotating shaft 49 is rotatably mounted on the second mounting bracket 48, the axial lead of the first rotating shaft 49 is parallel to the telescopic direction of the second telescopic rod 42, a plurality of second mounting blind holes 50 are formed in the circumferential outer wall of the first rotating shaft 49 around the circle center array, the second rotating shaft 51 is located in the second mounting blind holes 50 in a sliding manner, a second spring 52 is sleeved on the second rotating shaft 51, one end of the second spring 52 is fixedly connected to the second rotating shaft 51, the other end of the second spring is fixedly connected to the first rotating shaft 49, a third motor 6 is further mounted on the second mounting bracket 48, and the output shaft of the third motor 6 is fixedly connected to one end of the first rotating shaft 49.

In this embodiment, when the first conveyor belt conveys the substrate into the placing table, the substrate cannot be conveyed into the center of the placing table completely, the second telescopic rod descends, the third motor drives the first rotating shaft to rotate, and the first rotating shaft drives the second cylinder to shift the substrate towards the center of the placing table;

when the finished circuit boards are completely pressed, the pressing box body is sent out by the first push plate, when the finished circuit boards are sent to the placing table, the finished circuit boards cannot be directly taken away by the second transmission belt, the second telescopic rod descends, the third motor drives the first rotating shaft to rotate, and the first rotating shaft drives the second cylinder to stir the finished circuit boards towards the direction of the second transmission belt;

and after the finished circuit board is pressed at a high temperature, internal residual stress exists, the edge is likely to curl, subsequent processing is not facilitated, the second telescopic rod descends, the second spring on the second column body can vibrate and knock the finished circuit board to a small extent, and the residual stress in the product can be eliminated through vibration.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: modifications and equivalents may be made to the embodiments of the invention without departing from the spirit and scope of the invention, which is to be covered by the claims.
