[0002] Electronic products are getting smaller and smaller, and PCB circuit boards are becoming more and more sophisticated. The difficulty of manual inspection of PCB boards is increasing. The inspection speed is slower than that of machines. Long-term inspection is also prone to eye fatigue and missed inspections. In order to improve work efficiency, when the inner layer of the printed circuit board is being produced, it is necessary to perform automatic optical inspection (abbreviated as "AOI") on the product appearance. The image is collected by automatically scanning the PCB and compared with the qualified parameters in the database. The PCB defects are checked through image processing. This is mainly for quality control and provides effective help for improving product quality on subsequent production lines.

[0003] In order to improve the inspection speed and accuracy of the equipment and avoid the increase of false points, the board surface is usually cleaned with sticky paper and sticky roller before the product is inspected on the machine. This manual operation is time-consuming and labor-intensive, and has low production efficiency. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figures 1 to 5 A novel dust-sticking device shown in the figure comprises a shell 1 mounted on an optical detection instrument, a dust-sticking rubber roller 2 is mounted on the bottom of the shell 1, a dust-sticking paper roll 3 is arranged in the inner cavity of the shell 1, the dust-sticking paper roll 3 is fitted with the side facing the dust-sticking rubber roller 2, two groups of movable blocks 4 are movably arranged on both sides of the inner cavity of the shell 1, one side of one group of movable blocks 4 is rotatably connected with a fixed clamping seat 5 through a bearing, a support seat 6 is mounted on the surface of the other group of movable blocks 4, a side of the support seat 6 close to the fixed clamping seat 5 is rotatably connected with a movable clamping seat 7 through a bearing, the dust-sticking paper roll 3 is bonded to the outside of the winding drum 16, the fixed clamping seat 5 and the movable clamping seat 7 are clamped at both ends of the winding drum 16, an adjusting component for limiting the movable block 4 is arranged inside the shell 1, and a baffle 8 is movably arranged at the front end of the shell 1;

[0023] The position of the movable block 4 is automatically adjusted by the control box, so that the sticky paper roll 3 is attached to the outside of the sticky rubber roller 2, and the sticky rubber roller 2 is used to contact the PCB board to absorb the dust on the PCB board, and then transfer it to the sticky paper roll 3, and the sticky paper on the outermost layer of the sticky paper roll 3 is removed to continuously perform dust collection on the PCB board entering the optical detection instrument, thereby avoiding manual dust collection operations using the sticky paper roll 3 and the sticky rubber roller 2, and effectively improving the dust collection efficiency.

[0024] The adjustment component includes a cylinder 9 fixed on both sides of the inner cavity of the shell 1, and the piston rod of the cylinder 9 extends downward and is fixed to the top of the movable block 4. The movable block 4 can be limited by the cylinder 9 to ensure that the sticky paper roll 3 is always in contact with the sticky rubber roller 2, thereby preventing the sticky paper roll 3 from being separated from the sticky rubber roller 2 due to shaking, and preventing the sticky paper roll 3 from being used to remove dust attached to the sticky rubber roller 2.

[0025] Two sets of fixing seats 10 are fixedly installed on both sides of the bottom of the shell 1. The two ends of the sticky rubber roller 2 are installed on the inner side of the fixing seats 10 through bearings. The sticky rubber roller 2 can be installed through the fixing seats 10 to ensure the stability of the sticky rubber roller 2 so that it can continuously contact the PCB board below.

[0026] When the sticky paper roll 3 needs to be replaced, Figure 3 and Figure 4 As shown, the movable clamping seat 7 can be disassembled and assembled:

[0027] Four groups of mounting holes are provided on the surface of the support seat 6, and mounting screws 11 are movably provided in the mounting holes. The mounting screws 11 penetrate the support seat 6 and are threadedly connected to the movable block 4. The setting of the mounting screws 11 facilitates the disassembly and assembly of the support seat 6, thereby replacing the sticky paper roll 3 and the winding drum 16.

[0028] The front and back sides of the movable block 4 are provided with slide grooves 12, and the inner cavity of the slide groove 12 is slidably connected with a slide bar 13, and the slide bar 13 is fixedly installed in the inner cavity of the shell 1. The movable block 4 can slide on the slide bar 13 through the slide groove 12 to ensure the stability of the movable block 4, and at the same time facilitate the up and down position adjustment of the movable block 4.

[0029] Limiting seats 14 are fixed on both sides of the front side of the shell 1, and the baffle 8 is inserted into the inner cavity of the limiting seat 14. The baffle 8 is a transparent acrylic plate. Through the setting of the limiting seat 14, it is convenient to limit and support the baffle 8 to ensure the stability of the baffle 8.

[0030] It also includes a control box, which is electrically connected to the cylinder 9. Support feet 15 are installed on both sides of the bottom of the shell 1 for fixing the shell 1. Through the setting of the control box, the automation of the device can be ensured, the dust collection work can be automatically completed, and the manual workload can be reduced.

[0031] During specific use, the shell 1 is installed on the optical detection instrument through the mounting feet so that the shell 1 is located at the feed port of the PCB board. When the PCB board enters the optical detection instrument, it needs to pass under the sticky rubber roller 2. At this time, the sticky rubber roller 2 adsorbs the dust on the PCB board on the surface. Then, when the sticky rubber roller 2 contacts the sticky paper roll 3, the stickiness of the sticky paper roll 3 is used to remove the dust adsorbed on the sticky rubber roller 2. For a long time, the dust is adhered to the sticky paper roll 3. When the viscosity of the sticky paper roll 3 decreases, you only need to tear off the outer paper roll to continue using it, or replace the winding drum 16 with a new sticky paper roll 3.

[0032] It is worth noting that if Figure 5 As shown, the dust-sticking paper roll 3 is adhered to the outer side of the winding drum in layers without continuity. When the outermost layer is covered with dust, the outermost dust-sticking paper can be directly torn off.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
