[0005] In use, this utility model uses a hydraulic cylinder to drive the pressing plate downwards, pressing the pressing plate against the load-bearing plate to press the printed circuit board. However, in actual use, because the hydraulic cylinder directly drives the pressing plate to press the printed circuit board, the pressing plate is not easy to buffer the force during the pressing process, and it is also not easy to adjust the pressure of the pressing plate. Therefore, it is necessary to improve the pressing device for LED printed circuit board processing to solve the above problems. Utility Model Content

A sliding column 522 is slidably installed inside the sliding plate 513. An upper hot pressing plate 523 is fixedly installed at the bottom of the sliding column 522. A stop block 524 is fixedly installed at the top of the sliding column 522. A fixing spring 525 is fixedly installed between the top of the upper hot pressing plate 523 and the bottom of the sliding plate 513. A support column 526 is fixedly installed at the top of the sliding plate 513. A sliding frame 527 is slidably installed outside the support column 526. A threaded shaft 528 is rotatably installed at the top of the sliding plate 513.

[0034] Furthermore, a limiting groove is provided at the top of the sliding frame 527 and the corresponding position of the stop block 524, and the stop block 524 is inserted into the limiting groove, so that the sliding frame 527 can drive the sliding column 522 to be raised and lowered through the stop block 524.

[0035] Furthermore, the sliding frame 527 and the threaded shaft 528 are provided with threaded holes at corresponding positions, and the threaded shaft 528 is threadedly installed in the threaded holes, so that the threaded shaft 528 can drive the sliding frame 527 to slide and adjust. Example
