DETAILED DESCRIPTION

[0016] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] Reference Figure 1As shown, the embodiment of the present application discloses a fixing mechanism of a solder paste detector, comprising: a placement component 2, which is located in the projection measurement area of ​​the solder paste detector 1; a carrier component 3, which is rotatably arranged on the placement component 2; a clamping component, which is arranged on the carrier component 3 and is used to clamp a PCB board; a limit assembly, which is arranged on the carrier component 3 and is detachably connected to the placement component 2 and can limit the carrier component 3 from rotating.

[0018] In the utility model, by setting a clamping component, the PCB board clamping work can be completed; by setting a carrier component 3, the PCB board can be driven to rotate and turn over on the placement component 2; by setting a limit component, the rotational movement of the carrier component 3 on the placement component 2 can be limited, and different sides of the PCB board can be exposed under the solder paste detector 1; by using the utility model, after completing one clamping of the PCB board on the clamping component, the solder paste thickness detection requirements on both sides of the PCB board can be completed, the number of times the PCB board is disassembled and assembled is reduced, and the detection efficiency of the solder paste detector 1 can be effectively improved.

[0019] Furthermore, the mechanism also includes: a rotating shaft 31, which is rotatably arranged on the storage component 2 through a bearing, one end of which is connected to the loading component 3, and the other end of which is installed with a limiting component; wherein the limiting component includes: a limiting plate 51, which is fixedly arranged on the rotating shaft 31; a movable plate 52, which is arranged between the limiting plate 51 and the storage component 2 and can slide along the axial direction of the rotating shaft 31; a limiting pin 53, which is arranged parallel to the rotating shaft 31, one end of which is arranged on the limiting plate 51, and the other end passes through the movable plate 52; an elastic component 54, which is arranged between the movable plate 52 and the limiting plate 51; a latch 55, one end of which is arranged on the movable plate 52, and the other end extends toward the storage component 2; a pin hole, which is arranged on the storage component 2 for the latch 55 to be inserted.

[0020] Specifically, after completing the inspection operation on one side of the PCB board, the staff holds the movable plate 52, moves the movable plate 52 toward the limit plate 51, and squeezes the elastic component until the pin 55 exits the pin hole, removes the limit assembly from the placement component 2, and the shaft 31 can rotate freely; the staff rotates the shaft 31 180°, completes the flipping of the PCB board, and then releases the movable plate 52. Under the action of the elastic component 54, the movable plate 52 moves along the limit pin 53 until the pin 55 is reinserted into the placement component 2 to limit the rotation of the shaft 31.

[0021] By setting the limit components, the staff can quickly complete the turning over of the PCB board, ensuring the detection efficiency of the solder paste detector 1 on the solder paste thickness on both sides of the PCB board.

Rotating the turntable 22 can drive different storage components 2 to be within the projection measurement area of ​​the solder paste detector 1. When one of the storage components 2 is within the projection measurement area of ​​the solder paste detector 1 and is being measured, at the same time, the staff can disassemble and assemble the PCB boards on the remaining storage components 2. The disassembly and assembly and measurement of the PCB boards are carried out simultaneously without interfering with each other, which can effectively improve the inspection efficiency of the PCB boards.
