[0050] See Figure 1 and Figure 2 This utility model provides a circuit board testing press device, including: a vertical moving device 10, a guide post 30, a guide post lower fixing plate 50, and a fixture plate assembly 20. One end of the guide post 30 is fixedly connected to the vertical moving device 10; the other end of the guide post 30 is fixedly connected to the guide post lower fixing plate 50. The fixture plate assembly 20 includes a fixture movable plate 201 and a first fixture fixing plate 202. The first fixture fixing plate 202 is fixedly connected to the vertical moving device 10, and the fixture movable plate 201 and the first fixture fixing plate 202 are movably connected vertically. The vertical moving device 10 is used to drive the fixture movable plate 201 to move vertically, and when moving downward, it presses the circuit board or test board to be tested.

[0051] Specifically, such as Figure 1 and Figure 2As shown, the fixture plate assembly 20 can be moved up and down by the up-and-down moving device 10. When testing or inspecting a circuit board under test, the fixture plate assembly 20 can be moved downwards by the up-and-down moving device 10, thereby moving it to a position above the circuit board under test or the test board. The fixture movable plate 201 can then press down on the circuit board under test or the test board, facilitating testing and inspection. Since the fixture movable plate 201 and the first fixture fixed plate 202 are vertically and vertically connected, when the movable plate presses on the product under test or the test product, the fixture movable plate 201 can return upwards due to its own weight, reducing the weight on the testing fixture or the test product, preventing damage, and ensuring smooth circuit board testing or inspection.

[0052] like Figure 1 and Figure 2 As shown, the jig plate assembly 20 further includes a second jig fixing plate 203. The first jig fixing plate 202 is fixedly connected to the vertical moving device 10 via the second jig fixing plate 203. The first jig fixing plate 202 and the vertical moving device 10 are fixedly connected via the second jig fixing plate 203 to form a space for the vertical movement of the jig movable plate 201. Two second jig fixing plates 203 may be provided, located at opposite ends of the first jig fixing plate 202. One end of each second jig fixing plate 203 is fixedly connected to the first jig fixing plate 202, and the other end is fixedly connected to the vertical moving device 10. This allows the first jig fixing plate 202 and the vertical moving device 10 to form a certain movable space, enabling the jig movable plate 201 to move vertically within a certain range.

[0053] like Figure 1 and Figure 2 As shown, the fixture plate assembly 20 further includes a sliding shaft 204. A sliding shaft 204 guide sleeve is provided opposite to the first fixture fixing plate 202 and the sliding shaft 204. The fixture movable plate 201 is vertically connected to the first fixture fixing plate 202 via the sliding shaft 204 passing through the sliding shaft 204 guide sleeve. One end of the sliding shaft 204 is fixedly connected to the fixture movable plate 201, and the other end of the sliding shaft 204 is vertically connected to the first fixture fixing plate 202 via the sliding shaft 204 guide sleeve. This allows the fixture movable plate 201 to move vertically. When the movable plate presses on the product being tested or inspected, the fixture movable plate 201 can recover upwards due to its own weight, reducing the weight on the testing or inspected fixture and preventing damage to the product.

[0054] In one embodiment of this utility model, four sliding shafts 204 and four sliding shaft 204 guide sleeves are respectively provided, and the four sliding shafts 204 are respectively located near the four corners of the fixture movable plate 201; correspondingly, the four sliding shaft 204 guide sleeves are respectively located near the four corners of the first fixture fixed plate 202. By having the four sliding shafts 204 respectively arranged in the sliding shaft 204 guide sleeves, the fixture movable plate 201 can move up and down more evenly, ensuring that the fixture movable plate 201 moves up and down relatively horizontally, thereby better flattening the inspection product or test product.

[0055] like Figure 1 and Figure 2 As shown, the vertical moving device 10 includes: a cylinder 101, a guide post upper fixing plate 102, and a guide post movable plate 103. The cylinder 101 is mounted on the guide post upper fixing plate 102, and the vertical moving device 10 is also fixedly connected to one end of the guide post 30 through the guide post upper fixing plate 102.

That is, the cylinder 101 can be installed and fixed through the guide post upper fixing plate 102; at the same time, the guide post upper fixing plate 102 is also fixed to the upper end of the guide post 30. Since the telescopic rod of the cylinder 101 passes through the guide post upper fixing plate 102 and then connects with the guide post movable plate 103. Thus, the guide post movable plate 103 can move up and down under the drive of the cylinder 101, thereby driving the first fixture fixing plate 202 and the fixture movable plate 201 to move up and down.

[0056] Among them, such as Figure 1 and Figure 2 As shown in one embodiment of this utility model, the guide post movable plate 103 is further provided with a through hole corresponding to the guide post 30, and the guide post 30 is used to guide the guide post movable plate 103 to move up and down.
