The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0022] like Figures 1 to 4 As shown, this embodiment provides a PCB board re-inspection machine, including a housing 1, a feed port 11 and a discharge port 12 are respectively provided on both sides of the housing 1, a tooling plate 2 is provided between the feed port 11 and the discharge port 12, and two sets of parallel and spaced conveyor belts 3 are provided on the tooling plate 2;

[0023] A moving mechanism 4 is provided above the tooling plate 2, and a camera 41 is connected to the output end of the moving mechanism 4; a lifting mechanism 5 is provided below the tooling plate 2, and the lifting mechanism 5 is used to push the PCB board on the conveyor belt 3 toward the camera 41;

[0024] The housing 1 is provided with a display screen 6 and an operation keyboard 7 which are electrically connected to the camera 41 .

[0025] A distance adjusting mechanism 8 is also provided on the tooling plate 2, and the distance adjusting mechanism 8 includes a slide rail 81 and a first motor 82. The slide rail 81 is fixedly connected to the tooling plate 2, and a slide plate 83 is slidably connected to the slide rail 81, and a first nut 84 is fixedly connected to the slide plate 83. One group of conveyor belts 3 is installed on the slide plate 83, and the other group of conveyor belts 3 is installed on the tooling plate 2; the first motor 82 is installed on the tooling plate 2, and the output end of the first motor 82 is connected to a first screw rod 85 adapted to the first nut 84.

[0026] Specifically, a fixed plate having a symmetrical structure with the slide plate 83 is fixed on the tooling plate 2, and the other set of conveyor belts 3 is installed on the fixed plate to ensure that the two sets of conveyor belts 3 are parallel and symmetrically arranged. When the relative spacing distance between the two sets of conveyor belts 3 needs to be adjusted, the first motor 82 can be operated to drive the first screw rod 85 to rotate, thereby driving the first nut 84 to rotate, allowing the slide plate 83 to slide along the slide rail 81, thereby making the corresponding conveyor belt 3 closer to or farther from the other set of conveyor belts 3 to achieve the adjustment of the spacing distance, which can be applicable to the transportation of PCB boards of different widths and has a wider range of applications.

[0027] The lifting mechanism 5 includes a driver and two groups of push rods 51. The driver is installed in the housing 1 and below the tooling plate 2. The driver drives the push rods 51 to move in the vertical direction. A limit block 52 is fixed to the top of each group of push rods 51. The bottom end of each group of push rods 51 is arranged opposite to the output end of the driver. One group of push rods 51 is slidably connected to the slide plate 83, and the other group of push rods 51 is slidably connected to the tooling plate 2. Specifically, the tooling plate 2 is provided with avoidance through holes adapted to the push rods 51, so as to facilitate the push rods 51 to slide up and down and translate.

[0028] The driver includes a connecting plate 53 fixedly connected to the housing 1, a second nut 54 fixedly connected to the connecting plate 53, a slide bar 55 slidably connected to the connecting plate 53 in the vertical direction, a top plate 56 fixedly connected to the top of the slide bar 55, a second motor 57 installed at the bottom of the slide bar 55, and a second screw 58 matched with the second nut 54 connected to the output end of the second motor 57. The limit block 52 is L-shaped, and a guide slope 521 is provided at the top of the limit block 52; the two guide slopes 521 make the inner side of the top of the limit block 52 flared, so that the two sides of the PCB board are stuck on the limit block 52, ensuring smooth and reliable operation and avoiding tilting or skewing.

[0029] Specifically, when the lifting mechanism 5 is working, the second motor 57 drives the second screw rod 58 to rotate, drives the second nut 54, causes the slide rod 55 to slide relative to the connecting plate 53, and the top plate 56 pushes the top rod 51, thereby lifting the PCB board. At this time, the PCB board is limited between the two limit blocks 52.

[0030] The slide plate 83 and the tooling plate 2 are respectively provided with a limit cylinder 9, which is arranged corresponding to the output end of the conveyor belt 3. The output end of the limit cylinder 9 is connected to a stopper 91, and the limit cylinder 9 drives the stopper 91 to move to prevent the PCB board on the conveyor belt 3 from moving. When the PCB board needs to be re-inspected and lifted, the limit cylinder 9 will act to extend the output end, and the stopper 91 will stop the PCB board from continuing to move forward, so that the PCB board stops on the conveyor belt 3; under normal circumstances, the limit cylinder 9 is in a retracted state, and the stopper 91 will not prevent the PCB board from moving along the conveyor belt 3.

[0031] The moving mechanism 4 includes a mounting frame 42, on which a first linear module 43 is mounted, and a second linear module 44 is mounted at the output end of the first linear module 43, and the working direction of the first linear module 43 is set horizontally and vertically to the conveying direction of the conveyor belt 3; a camera 41 is mounted at the output end of the second linear module 44, and the working direction of the second linear module 44 is set parallel to the conveying direction of the conveyor belt 3. Specifically, under the connection between the first linear module 43 and the second linear module 44, the camera 41 can be moved to any position of the horizontal coordinate system, that is, moved to any position on the corresponding PCB board plane, which can ensure the detection accuracy.

[0032] The four corners at the bottom of the housing 1 are provided with supporting feet 13, and the top of the housing 1 is hinged with a movable window 14. Specifically, the movable window 14 can be rotated to open the housing 1 for easy maintenance and repair. A controller is provided inside the housing 1, and the controller is electrically connected to various electrical components to achieve automatic control, which is more intelligent; a warning light 15 is provided on the top of the housing 1 to intuitively display the working status of the re-inspection machine.

[0033] The specific working principle of the utility model is as follows: the PCB board enters from the feed port 11, is transported by the conveyor belt 3, and moves to the middle position. When re-inspection is required, the limit cylinder 9 will act first to allow the block 91 to block the PCB board, and then the lifting mechanism 5 will act to lift the PCB board and bring the PCB close to the camera 41. Finally, the moving mechanism 4 will act to move the camera 41 to the specified position for shooting, and the shooting position will be magnified and presented through the display screen 6 for better detection; after the detection is completed, the lifting mechanism 5 will act in the opposite direction to allow the PCB board to return to the conveyor belt 3, and the limit cylinder 9 will drive the block 91 to retract, release the PCB board, and the PCB board will be output from the discharge material 12, thereby completing the re-inspection work; it should be noted that the specific working process of each mechanism refers to the detailed description above, and will not be repeated here one by one.

[0034] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
