Description

Technical Field

[0001] The utility model relates to the technical field of PCB board jigs, in particular to a PCB board jig with an external spring. Background Technique

[0002] With the increasing use of PCB boards and the growing market demand, there are more and more manufacturers producing PCB boards. During the manufacturing process of PCB boards, multiple processes need to be carried out on the PCB boards. No matter what process is carried out, the PCB board needs to be fixed. Sometimes, the PCB board needs to be placed horizontally for processing.

[0003] When the existing PCB board clamping devices are in use, most of them drive the clamping blocks to clamp the PCB board through a motor. During clamping, due to the different thicknesses and lengths of the plates, the clamping plate will warp or the size of the clamping table does not match, resulting in a small application range.

[0004] Therefore, a PCB board jig with an external spring is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a PCB board jig with an external spring to solve the problems of local warping of the clamping plate and a small application range existing in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A PCB board jig with an external spring, including a mounting plate and a connecting plate. An adjusting mechanism is fixedly installed on the top surface of the mounting plate, and a clamping mechanism is fixedly installed on the top surface of the connecting plate. The clamping mechanism includes a fixing member, a cylinder two is fixedly installed on the side of the fixing member, a rubber head is fixedly installed on the end face of the push rod of the cylinder two, a hinge member is fixedly installed on the top surface of the connecting plate, a clamping block is hingedly installed inside the hinge member, an upper mounting plate is fixedly installed on the bottom end face of the clamping block, a telescopic rod is fixedly installed on the bottom end face of the upper mounting plate, a reset spring is fixedly installed on the bottom end face of the upper mounting plate, the bottom end face of the telescopic rod is fixedly installed with a lower mounting plate, and the top end face of the lower mounting plate is fixedly connected to the bottom end face of the reset spring, which can control the inclination degree of the clamping plate, adapt to different PCB boards, improve the application range of the device, and improve the practicability of the device.

[0007] Preferably, a connecting rod is fixedly installed on the side of the clamping block, a counterweight is fixedly installed on the end face of the connecting rod, and a limiting block is fixedly installed on the top surface of the connecting plate.

The bottom end surface of the support rod is fixedly connected to the top end surface of the mounting plate. A fixing sleeve is fixedly installed on the side surface of the support rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1) For the PCB board clamp with an external spring, when it is necessary to clamp the PCB board, place the PCB board above the connecting plate and limit it through the limit block. Then, open the second cylinder. The second cylinder pushes the push rod forward, and then the rubber head pushes the clamping block to rotate around the hinge member, driving the clamping block and the rubber plate to clamp the PCB board. During clamping, the upper mounting plate, the lower mounting plate, the return spring, and the telescopic rod adapt to the inclination angle of the board. When clamping is not required, the counterweight drives the connecting rod and the clamping block to deflect, lifting the clamping plate, which can control the inclination degree of the clamping plate, adapt to different PCB boards, improve the application range of the device, and enhance the practicability of the device.
