The cover body 505 is larger than the structural member 202; the microcontroller board 503 is provided with an image processing module, a storage module, a comparison module and a warning module, etc. The image processing module is used to enhance the image taken by the high-definition camera 502, so that minor defects are easier to be found, the storage module is used to save the image of the standard sample, the comparison module is used to compare the processed image with the image of the standard sample to evaluate the flatness of the layer, and the warning module reminds the subsequent material collection staff or material collection device when the spraying surface of the structural member 202 is uneven, and the structural member 202 is removed and placed in the collection area for subsequent re-spraying.

[0023] The spraying assembly 3 includes two electric slide rails 301, which are respectively installed on the inner walls of both sides of the box body 1 by screws, and sliders 302 are slidably installed on the two electric slide rails 301. The two sliders 302 are connected by a cross bar 303, and the lower surface of the cross bar 303 is located at the structural member 202 and is provided with three nozzles 304. The upper surface of the cross bar 303 is connected with a feed pipe 305, and the feed pipe 305 is connected to the feed ports of the three nozzles 304. The length of the two electric slide rails 301 is the same as the length of the inner wall of the box body 1. Both ends of the cross bar 303 are connected to the sliders 302 by bolts. The feed pipe 305 is a telescopic pipe, and the end of the feed pipe 305 passes through the side wall of the box body 1 and extends to the outside to be connected to the paint box, wherein a pump body is provided outside the paint box, and the feed pipe 305 is connected to the pump body; A partition 103 is fixed to the inner top of the box 1, and four fans 1031 arranged in a square are installed on the partition 103. A collecting box 104 is slidably installed on the inner bottom of the box 1. A controller 8 is installed on the outer wall of the box 1. The controller 8 is connected to the spray assembly 3 and the protective mechanism 4 through a wire. One end of the collecting box 104 passes through the outer wall of the box 1, and a filter is installed on the top of the box 1.

[0024] When spraying paint on the structure 202 (shell) of the laptop computer, firstly, the annular conveyor line 2 is started through the external control device, and the structure 202 to be sprayed is placed on the suction cup 201 moving toward the feed through hole 101 for adsorption and fixation. The annular conveyor line 2 drives the structure 202 to be sprayed through the feed through hole 101 into the box body 1 and then stops running. At this time, the controller 8 starts the pump body, and the pump body feeds the paint in the paint box into the three nozzles 304 through the feed pipe 305 and sprays it out. At the same time, the two electric slide rails 301 work to control the sliders 302 to slide, and the moving two sliders 302 drive the cross bar 303 to move, and the cross bar 303 drives the three nozzles 304 to move and stretch the feed pipe 305, so that the three nozzles 304 pass through the structure 202 and spray its surface until it moves to the other end of the electric slide rail 301 and stops working and feeding. Then the driving source in the lifting assembly 6 works, so that its actuator pushes the cover body 5 to move downward, and the downwardly moving cover body 5 pushes the actuator of the closing assembly 7 at the bottom to deflect at an angle to both sides, and the actuator of the closing assembly 7 contacts and slides with the outer wall of the cover body 5, so that the bottom opening of the cover body 5 is exposed, and as the lifting assembly 6 works, the bottom of the cover body 5 will contact the upper surface of the annular conveyor line 2, and cover the sprayed structural member 202 therein, at this time, the four fans 1031 work to blow the external air into the box body 1 through the filter, so that the paint micro-particles contained in the internal air are blown into the collection box 104 below and attached, thereby greatly reducing the presence of tiny particles in the air, and at the same time, the cover body 5 can prevent the particles from being deposited on the surface of the structural member 202 when blowing, thereby improving the quality of spraying; Then the microcontroller board 503 in the cover body 5 returns a start signal, so that the two fill lights 504 are illuminated, and the high-definition cameras 502 in three different directions take pictures of the sprayed structural member 202 under the illumination of the fill lights 504, and upload the captured images to the microcontroller board 503, and the image processing module performs image enhancement, and then compares the image with the image of the standard brick sample saved in the storage module through the comparison module to evaluate whether the coating of the structural member 202 is flat. If it is evaluated to be uneven, the warning module will work to send an alarm to the subsequent material collection staff or the material collection device will send a control program, and the structural member 202 will be removed and placed in the collection area for subsequent re-spraying. When it is flat and integrated (and the surface is flat), the protective mechanism 4 moves up and resets, and the annular conveyor line 2 works at the same time, and the sprayed structural member 202 is moved out of the box through the discharge hole 102 and removed, and the above steps are repeated for the structural member 202 to be sprayed.

[0025] Therefore, after the structural member 202 is sprayed, the present application can cover the structural member 202 and then ventilate to blow the paint particles floating in the air into the collection box 104 at the bottom to prevent them from depositing on the surface, improve the smoothness of the spraying, and also detect and determine whether the spraying is smooth.

[0026] See also Figure 3-8 As shown, the lifting assembly 6 includes a driving motor 601, which is installed at the center of the inner top of the box body 1 by bolts. A through hole 1032 is opened in the center of the partition 103. The output end of the driving motor 601 is connected to a screw rod 602 passing through the through hole 1032. A movable sleeve 603 is sleeved on the screw rod 602. The bottom end of the movable sleeve 603 passes through the through hole 1032 and is fixedly connected to the top wall of the cover body 5. Limiting plates 604 are welded on both sides of the top of the cover body 5. The outsides of the two limiting plates 604 are sleeved with sleeve plates 605. The top ends of the two sleeve plates 605 are fixedly connected to the lower surface of the partition 103. The diameter of the through hole 1032 matches the outer diameter of the movable sleeve 603. The closing assembly 7 includes two baffles 701, and the two baffles 701 are symmetrically arranged at the bottom opening of the cover body 5. The ends of the two baffles 701 that are close to each other are rotatably installed with rollers 7011. The two side walls of the other ends of the two baffles 701 are provided with first installation slots 706. The two first installation slots 706 are provided with plug-in rods 703. Four connecting rods 705 are evenly welded on the lower surface of the partition 103. The bottom ends of the four connecting rods 705 are welded with fixing plates 702. The four fixing plates 702 are respectively located at the two side ends of the two baffles 701, and the four The end faces of the fixing plates 702 are provided with second mounting slots 707, the ends of each of the plug-in rods 703 are inserted into the second mounting slots 707 and are rotatably connected thereto, the widths of the two baffles 701 are the same as the width of the cover body 5, the outer walls of the two rollers 7011 are in contact with each other, each of the plug-in rods 703 is fixedly connected to the slot wall of the first mounting slot 706, a torque spring 704 is provided between each of the first mounting slots 706 and the second mounting slots 707, each of the torque springs 704 is sleeved on the plug-in rod 703, and the two baffles 701 are made of plastic.

[0027] When the driving motor 601 in the lifting assembly 6 works, the output end of the driving motor 601 drives the screw rod 602 to rotate. At this time, the movable sleeve 603 drives the cover body 5 to move downward under the action of the limit plate 604 and the sleeve plate 605 following the rotation of the screw rod 602. The downward moving cover body 5 drives the limit plate 604 to extend out of the sleeve plate 605, and pushes the two baffles 701 at the bottom to deflect to both sides at an angle when the cover body 5 moves downward. The baffle 701 rotates on the fixed plate 702 through the plug-in rod 703, and stores energy for the torque spring 704, so that the opening at the bottom of the cover body 5 is exposed. At this time, the two baffles 701 contact the outer walls of the cover body 5 on both sides under the action of the torque spring 704, and reduce the friction between the cover body 5 and the cover body 5 through the roller 7011, and then the two baffles 701 can be used to close the opening when the cover body 5 is moved up and reset, so as to prevent the paint microparticles from floating into the cover body 5 during spraying and blocking the high-definition camera 502 and the fill light 504.

[0028] The working principle of the present invention is: When spraying paint on the structure 202 (shell) of the laptop computer, firstly, the annular conveyor line 2 is started through the external control device, and the structure 202 to be sprayed is placed on the suction cup 201 moving toward the feed through hole 101 for adsorption and fixation. The annular conveyor line 2 drives the structure 202 to be sprayed through the feed through hole 101 into the box body 1 and then stops running. At this time, the controller 8 starts the pump body, and the pump body feeds the paint in the paint box into the three nozzles 304 through the feed pipe 305 and sprays it out. At the same time, the two electric slide rails 301 work to control the sliders 302 to slide, and the moving two sliders 302 drive the cross bar 303 to move, and the cross bar 303 drives the three nozzles 304 to move and stretch the feed pipe 305, so that the three nozzles 304 pass through the structure 202 and spray its surface until it moves to the other end of the electric slide rail 301 and stops working and feeding. Then the driving motor 601 in the lifting assembly 6 works, and the output end of the driving motor 601 drives the screw rod 602 to rotate. At this time, the movable sleeve 603 drives the cover body 5 to move downward under the action of the limit plate 604 and the sleeve plate 605 following the rotation of the screw rod 602. The downward moving cover body 5 drives the limit plate 604 to extend out of the sleeve plate 605, and the two baffles 701 at the bottom of the cover body 5 are pushed to deflect to both sides at an angle. The baffle 701 rotates on the fixed plate 702 through the plug-in rod 703, and stores energy in the torque spring 704, so that the opening at the bottom of the cover body 5 is exposed. At this time, the two baffles 701 are in contact with the cover body 5 under the action of the torque spring 704. The outer walls on both sides are in contact, and the friction between the cover body 5 and the roller 7011 is reduced, so that the bottom opening of the cover body 5 is exposed, and as the lifting assembly 6 works, the bottom of the cover body 5 will contact the upper surface of the annular conveyor line 2, and cover the sprayed structural member 202 therein. At this time, the four fans 1031 work to blow the external air into the box body 1 through the filter, so that the paint micro-particles contained in the internal air are blown into the collection box 104 below and attached, thereby greatly reducing the presence of tiny particles in the air. At the same time, the cover body 5 can prevent the particles from being deposited on the surface of the structural member 202 when blowing, thereby improving the quality of spraying; Then the microcontroller board 503 in the cover body 5 returns a start signal, so that the two fill lights 504 are illuminated, and the high-definition cameras 502 in three different directions take pictures of the sprayed structural member 202 under the illumination of the fill lights 504, and upload the captured images to the microcontroller board 503, and the image processing module performs image enhancement, and then compares the image with the image of the standard brick sample saved in the storage module through the comparison module to evaluate whether the coating of the structural member 202 is flat. If it is evaluated to be uneven, the warning module will work to send an alarm to the subsequent material collection staff or the material collection device will send a control program, and the structural member 202 will be removed and placed in the collection area for subsequent re-spraying. When it is flat and integrated (and the surface is flat), the protective mechanism 4 moves up and resets, and the annular conveyor line 2 works at the same time, and the sprayed structural member 202 is moved out of the box through the discharge hole 102 and removed, and the above steps are repeated for the structural member 202 to be sprayed.
