[0024] Embodiment

[0025] Provided by Figures 1-4 A detection device for PCB board mounting production, comprising a workbench 1 and a vision camera 6;

[0026] A positioning plate 11 is assembled on one side of the upper end surface of the workbench 1, and a top plate 12 is assembled on one side of the upper end of the positioning plate 11;

[0027] A set of rotating assemblies 2 are assembled on one side of the workbench 1;

[0028] The rotating assembly 2 includes a guide rod cylinder 20. A cylinder guide rod is connected to the output end of the guide rod cylinder 20, and a connecting plate 21 is connected to one end of the cylinder guide rod. A rack 22 is assembled at the lower end of the connecting plate 21. A limiting block 13 is assembled on one side of the upper end surface of the workbench 1. A rotating rod 23 penetrates through one side of the limiting block 13 and extends through the positioning plate 11. A gear 24 is assembled on the outer part of the rotating rod 23 and the gear 24 is located between the limiting block 13 and the positioning plate 11. The gear 24 is meshed with the rack 22. A fixing plate 25 is assembled on the outer part of one end of the rotating rod 23, and a mounting plate 3 is assembled on one side of the fixing plate 25;

[0029] A plurality of mounting grooves are arranged in a linear array on the mounting plate 3, and a set of clamping assemblies 4 are assembled in each of the plurality of mounting grooves;

[0030] A set of transmission components 5 is assembled on one side of the lower end surface of the top plate 12.

[0031] In this embodiment, through the mutual cooperation between the components in the rotating assembly 2, by controlling the guide rod cylinder 20, the rack 22 is driven to move, driving the gear 24 engaged with the rack 22 to rotate, and finally driving the mounting plate 3 to rotate and turn over, so that the vision camera 6 performs vision inspection on the PCB board placed on the mounting plate 3. Compared with manual operation, this device can greatly improve production efficiency, can complete the front and back scanning of the PCB board faster and more stably, thus accelerating the entire production process, reducing the mistakes of manual flipping, ensuring that each PCB board can be accurately scanned, improving the consistency and reliability of products, and reducing the generation of defective products.

[0032] Specifically, referring to Figures 1-3 , the clamping component 4 includes a mounting frame 40. Four rectangular grooves are arranged inside the mounting frame 40, and compression springs 41 are hooked in the four rectangular grooves. The four compression springs 41 are distributed in a rectangle, and the other ends of the four compression springs 41 are all hooked with rubber abutting blocks 42. One side of the rubber abutting block 42 is provided with an inclined surface and a groove is arranged in the middle section.

[0033] In this embodiment, when the PCB board needs to be installed, the PCB board is aligned with the mounting frame 40 and pressed downward, so that the PCB board contacts the inclined surfaces on one side of the four rubber abutting blocks 42, and correspondingly compresses the compression springs 41 hooked on one side of each rubber abutting block 42, making the compression springs 41 in a tense state. When the PCB board reaches the groove in the middle section of the rubber abutting block 42, through the elastic force and external tension of the set compression springs 41, the rubber abutting block 42 is pushed to move towards one side of the PCB board, and finally the PCB board is clamped between the four rubber abutting blocks 42.

[0034] Specifically, referring to Figures 1-4 , the transmission component 5 includes a lead screw base 50. The lead screw base 50 has a rectangular cavity, and a driving motor 51 is assembled in the rectangular cavity. The output end of the driving motor 51 is connected with a threaded lead screw 52. A sliding shaft sleeve 53 is engaged and slidably arranged outside the threaded lead screw 52. A slider 54 is assembled outside the sliding shaft sleeve 53. The vision camera 6 is assembled at the lower end of the slider 54.

[0035] In this embodiment, by controlling the driving motor 51, the driving motor 51 drives the threaded lead screw 52 connected to the output end to rotate. When the threaded lead screw 52 rotates, the sliding shaft sleeve 53 engaged and slidably arranged outside the threaded lead screw 52 drives the externally mounted slider 54 to move within the stroke range of the threaded lead screw 52, and finally drives the vision camera 6 to move to perform vision inspection on the front side of each PCB board on the mounting plate 3.

[0036] Specifically, referring toFigures 1-2 , two side limit plates 26 are assembled on one side of the positioning plate 11, and the two side limit plates 26 are arranged in parallel. A slide bar 27 is assembled between the two side limit plates 26, and the slide bar 27 penetrates through the connecting plate 21.

[0037] In this embodiment, the provided slide bar 27 is used to limit the connecting plate 21, so that the connecting plate 21 can be more stable when moving.

[0038] Specifically, referring to Figure 4 , two limit rods 55 are assembled on one side of the driving motor 51, and the two limit rods 55 both penetrate through the slider 54.

[0039] In this embodiment, the provided two limit rods 55 are used to limit the slider 54, so that the slider 54 can be more stable and smooth when moving, and the overall stability of the device is improved.

[0040] Specifically, referring to Figures 1-4 , the connection between the vision camera 6 and the slider 54 is of a detachable design.

[0041] In this embodiment, the connection between the vision camera 6 and the slider 54 is of a detachable design, which makes it convenient to replace and repair the vision camera 6 later and reduces the workload of maintenance personnel.

[0042] The detection device for PCB board mounting production of the present utility model:

[0043] During actual use, first connect the set guide rod cylinder 20 to an external air source and give the cylinder an output value, connect the set drive motor 51 to an external power source, and then place the PCB board to be detected in each clamping assembly 4. Through the tension and elastic force of the set compression spring 41 acting outward, the two sides of the PCB board are limited by four rubber abutting blocks 42, so that the PCB board is fixed. Subsequently, start and control the drive motor 51, so that the drive motor 51 drives the threaded lead screw 52 connected to the output end to rotate. When the threaded lead screw 52 rotates, the sliding shaft sleeve 53 meshed and slidably arranged outside the threaded lead screw 52 drives the externally installed slider 54 to move within the stroke range of the threaded lead screw 52, and finally drives the vision camera 6 to move to visually inspect the front of each PCB board on the mounting plate 3. When the front of each PCB board has been inspected, control the set guide rod cylinder 20, so that the guide rod cylinder 20 controls the cylinder rod connected to the output end to extend to one side, thereby driving the connecting plate 21, so that the rack 22 at the lower end of the connecting plate 21 is driven to move. The set rack 22 is meshed and connected with the gear 24. When the rack 22 moves, it drives the gear 24 to rotate, and finally drives the rotating rod 23 to rotate, so that the mounting plate 3 is driven to rotate and turn over. Subsequently, control the drive motor 51 so that the vision camera 6 is driven to detect the back of the PCB board. After the detection is completed, pressing down on the PCB board clamped between the four rubber abutting blocks 42 can remove the PCB board. Subsequently, repeating the above steps can continuously and quickly perform visual inspection, which is convenient and fast.
