[0023] Depend on Figure 1-4 The utility model relates to a computer back cover surface treatment spraying device, comprising a collecting bottom box 1, a spraying assembly 2 is provided above the collecting bottom box 1, and a supporting adjustment assembly 3 is installed on the top of the collecting bottom box 1;

[0024] The spraying assembly 2 includes a crossbeam 201 arranged above the collecting bottom box 1, a spray liquid storage tank 204 is installed on the top of the crossbeam 201, a distribution pipe 205 is installed on the bottom end of the crossbeam 201, and a nozzle 206 is installed equidistantly on the bottom end of the distribution pipe 205. The spray liquid storage tank 204 and the distribution pipe 205 are connected by an infusion hose, and two sliding support frames 202 are installed at the bottom end of the crossbeam 201. The two sliding support frames 202 are symmetrically arranged on both sides of the collecting bottom box 1, and sliding grooves 203 are symmetrically opened on both sides of the collecting bottom box 1. The sliding support frames 202 are slidably connected to the sliding grooves 203. A rotating screw 207 is rotatably installed inside one of the sliding grooves 203, and the rotating screw 207 is threadedly connected to the sliding support frame 202. One end of the rotating screw 207 is fixedly connected to the output shaft of the drive motor 208, and the drive motor 208 is fixedly installed on the back of the collecting bottom box 1.

[0025] The support and adjustment component 3 includes two fixed slides 301 symmetrically mounted on the top of the collection bottom box 1, two lower sliding seats 302 are slidably mounted inside the fixed slide 301, and a movable slide 305 is fixedly mounted on the top of the lower sliding seat 302. A double-headed screw 303 is rotatably mounted inside the fixed slide 301, and the two lower sliding seats 302 are respectively threadedly connected to two thread grooves on the double-headed screw 303 with opposite directions. One end of the double-headed screw 303 is fixedly connected to the output shaft of the servo motor 304. The servo motor 304 is fixedly mounted on the fixed slide 301, and the upper The sliding seat 306 is provided with a rear shell support at the top of the upper sliding seat 306. The side wall of the upper sliding seat 306 is provided with tooth grooves 308 at equal intervals. The side wall of the movable slide 305 is provided with a side groove 307. The inner side of the side groove 307 is provided with a gear 309. The gear 309 is engaged with the tooth groove 308. The gear 309 is fixedly connected to the output shaft of the stepping motor 310. The stepping motor 310 is fixedly installed on the movable slide 305. The rear shell support includes a support plate 311 fixedly installed on the top of the upper sliding seat 306. The top of the support plate 311 is fixedly installed with a suction cup 312. The top of the upper sliding seat 306 is provided with a support plate 311. The support plate 311 is located below the rear shell, and the top wall of the suction cup 312 set at the top of the support plate 311 contacts the bottom wall of the rear shell to support the rear shell, and the piston 314 moves to fix the suction cup 312 and the rear shell under negative pressure, thereby fixing the rear shell without causing any obstruction to the top of the rear shell, making it convenient for spraying. An internal groove 313 is provided inside the support plate 311, and the internal groove 313 is connected to the suction cup 312. A piston 314 is movably installed inside the internal groove 313. Exhaust holes 316 are equidistantly provided at the top of the internal groove 313. The exhaust holes 316 are located at the piston 314 away from the suction cup 312. On one side of the piston 314, a return spring 315 is fixedly installed on the side away from the suction cup 312, a magnetic block 317 is installed on the piston 314, and an electromagnet 318 is fixedly installed on the inner wall of the end of the internal groove 313. When the double-headed screw 303 rotates, it can drive the two support plates 311 to move relative to each other, and when the gear 309 rotates, it can drive the support plate 311 to move along the movable slide 305, so as to facilitate the adjustment of the positions of the four suction cups 312 and facilitate the support and fixation of rear shells of different sizes. At the same time, when the suction cup 312 on one side is fixed with the rear shell under negative pressure, it can drive the rear shell to move horizontally for position adjustment, which is convenient for spraying.

[0026] Working principle: When working, first adjust the position of the four suction cups 312. During adjustment, the servo motor 304 is controlled to start, so that the double-headed screw 303 rotates, which can drive the two lower sliding seats 302 to move relative to each other. At the same time, the stepping motor 310 is controlled to start, which can rotate the gear 309, which moves along the upper sliding seat 306 and the movable slide 305 through the tooth groove 308, thereby adjusting the position of the four suction cups 312 to facilitate the support of computer back cases of different sizes.

[0027] After adjustment, the computer back cover is placed on top of the four suction cups 312 so that the top walls of the suction cups 312 are in close contact with the computer back cover. Then, the electromagnet 318 is energized to generate a repulsive force on the magnetic block 317, pushing the piston 314 toward the side away from the suction cups 312. This creates a negative pressure between the suction cups 312 and the computer back cover, thereby fixing the back cover under negative pressure. Since the fixing position is located below the back cover, there is no obstacle on the top of the back cover, making it easier to spray the back cover surface.

[0028] Then, the driving motor 208 is turned on to rotate the rotating screw 207, thereby driving the crossbeam 201 to move along the sliding groove 203. At the same time, the pump body on the spray liquid storage tank 204 is turned on to drive the spray liquid to spray downward from each nozzle 206 to the surface of the rear shell, thereby completing the rear shell spraying.

[0029] Due to the distance between two adjacent nozzles 206, there may be a situation where the position on the rear shell corresponding to the two nozzles 206 is not sprayed during spraying. At this time, the electromagnet 318 on one side of the support plate 311 is de-energized, so that the piston 314 moves back under the elastic force of the return spring 315, so that the suction cup 312 on one side is separated from the rear shell. Then, the two stepping motors 310 on the other side are turned on to drive the sliding seat 306 on the other side to move, thereby driving the rear shell to move laterally, so as to adjust the spraying position and improve the spraying effect.

[0030] During the spraying process, excess spraying liquid flows downward along the surface of the rear shell to the inside of the collection bottom box 1, which is convenient for subsequent processing.
