Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection devices, and particularly relates to a conveying detection device. BACKGROUND

[0002] In the vertical coating production process of a PCB board, the thickness change of the substrate needs to be monitored, so as to obtain the coating thickness, so as to make adaptive adjustment in the next process.

[0003] The existing thickness detection device for the PCB board generally comprises a conveying mechanism and a detection mechanism. The PCB board to be detected is conveyed to the detection mechanism for thickness detection through the conveying mechanism. A push plate is installed on the conveying mechanism. The push plate is driven by a motor or a cylinder to push the PCB board to be detected, so as to adjust the position of the PCB board on the conveying mechanism, so that the conveying mechanism can accurately convey the PCB board to the detection position in the detection mechanism for thickness detection. The PCB board has a consistent position when passing through the detection position to obtain stable detection results.

[0004] According to the related technical scheme in the above, the inventors believe that the following defects exist: when the thickness of the MiniLED and other PCB boards is detected, due to the characteristics of thin and brittle of the MiniLED and other PCB boards, when the push plate is driven by the motor or the cylinder to push the PCB board, the motor and the cylinder can control the stroke, but there is a possibility that the push force is too large to cause the deformation of the PCB board, causing damage to the PCB board, and therefore further improvement is needed.

[0054] The implementation principle of the embodiment 1 of the application is as follows: when the position of the PCB board is adjusted, the driving motor 234 is started to drive the connecting seat 21 to slide along the length direction of the sliding rail 111, so that the connecting seat 21 is forced to move towards the side close to the alignment plate 14, and the connecting seat 21 drives the sliding seat 22 and the pushing column 221 to move towards the side close to the alignment plate 14, when the pushing column 221 abuts against the PCB board, the sliding seat 22 needs to slide relative to the connecting seat 21 to overcome the frictional force between the PCB board and the conveying roller 12, so as to pull the tension spring 222 and force the limiting column 224 to slide along the limiting groove 211, so as to form a sliding buffer space, and the possibility that the pushing column 221 pushes the PCB board with excessive pushing force to cause the PCB board to be bent and deformed is reduced.
