Technical Field

[0001] The utility model relates to the technical field of computer shell processing, and more specifically, to a rotary paint spraying device for a computer shell. Background Art

[0002] In the manufacturing process of computer casing, painting is an important link. Painting can form a protective layer on the surface of the computer casing, which can prevent dust, dirt, moisture, chemicals and other harmful substances in the external environment from corroding the internal electronic components of the computer. The surface of the computer casing treated with painting is harder and can resist a certain degree of scratches and collisions. Therefore, painting the surface of the laptop casing is an indispensable process, so spraying equipment is needed.

[0003] Traditional spraying methods often use manual handheld spray guns, which is not only inefficient, but also difficult to ensure the spraying effect. Especially for computer housings of different sizes, it is necessary to frequently replace the fixture or adjust the position of the spray gun, which increases the complexity and time cost of the operation. At the same time, traditional spraying devices are prone to uneven spraying and dead corners, which further affects the spraying quality. In response to the above problems, this device was invented.

[0028] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] See attached Figure 1-Figure 5 The rotary painting device for a computer housing of this embodiment includes a base 1, a fixing mechanism 2, a driving assembly 3 and a spraying assembly 4, which can realize the clamping, rotation and spraying of the computer housing, improve the spraying efficiency, and spray evenly, thereby improving the spraying quality.

[0031] See attached Figure 1 , Figure 2 and Figure 5The fixing mechanism 2 includes a column 201 rotatably mounted on the machine base 1, a pad 202 is fixedly mounted on the top of the column 201, mounting seats 203 are fixedly mounted on both sides of the top of the pad 202, a double-rotation screw 204 is rotatably mounted between the mounting seats 203 on both sides, and a guide rod 205 is fixedly mounted between the mounting seats 203 on both sides. Specifically, two guide rods 205 are provided, and are respectively arranged on both sides of the double-rotation screw 204, and clamping plates 206 are threadedly connected on both sides of the double-rotation screw 204, and the guide rod 205 passes through the two clamping plates 206, thereby realizing the limiting of the clamping plates 206, and the clamping plates 206 on both sides are symmetrically arranged, and a hand wheel 207 is fixedly mounted on one end of the double-rotation screw 204. When in use, the hand wheel 207 is turned to realize the rotation of the double-rotation screw 204.

[0032] When in use, the double-rotation screw 204 can be rotated by turning the hand wheel 207. During the rotation of the double-rotation screw 204, the clamping plates 206 on both sides move toward each other to clamp computer housings of different sizes, and the clamping state is stable, providing a good foundation for the subsequent spraying process.

[0033] See attached Figure 2 and Figure 3 The driving assembly 3 is arranged below the pad 202 to drive the column 201 to rotate. The driving assembly 3 includes a gear ring 301 fixedly mounted on the column 201. A motor 302 is fixedly mounted on the base 1. The output shaft of the motor 302 is connected with a gear 303 meshing with the gear ring 301. When in use, the motor 302 is turned on, and the motor 302 drives the gear 303 to rotate. Since the gear ring 301 and the gear 303 are meshingly connected, the gear ring 301 will also rotate synchronously, thereby realizing the rotation of the column 201, that is, realizing the rotation of the computer housing in the clamping state, thereby ensuring the uniformity of spraying and avoiding dead angles in spraying. At the same time, the gear 303 is used as an active component to drive the gear ring 301 to rotate, thereby reducing the rotation speed of the column 201, so that the computer housing rotates at a lower speed, ensuring the painting effect.

[0034] See attached Figure 1 and Figure 5 The spraying assembly 4 is arranged above the machine base 1. The spraying assembly 4 includes a bracket 401 fixedly installed on the top of the machine base 1. A paint collecting tank 402 is fixedly installed on the bracket 401. The paint collecting tank 402 is connected to multiple nozzles 403. The nozzles 403 are arranged toward the pad 202, so that the paint can be evenly sprayed on various parts of the computer casing. The top of the paint collecting tank 402 is connected to a paint inlet pipe 404. The paint inlet pipe 404 is connected to an external liquid pump and paint. Under the action of the liquid pump, the paint is transported to the paint collecting tank 402, so that the replenishment of paint is convenient and quick.

[0035] See attached Figure 4and Figure 5 A plurality of plug-in slots 7 are evenly arranged on the top of the machine base 1, and a transparent protective cover 8 is arranged above the machine base 1. The transparent protective cover 8 can not only prevent paint from splashing, but also observe the spraying process, which is convenient for timely adjustment. The bottom of the transparent protective cover 8 is fixedly installed with plug-in blocks 9 equal to the number of plug-in slots 7. The design of the plug-in slots 7 and the plug-in blocks 9 makes the installation and removal of the transparent protective cover 8 simple and convenient.

[0036] In another embodiment, referring to the attached Figure 3 and Figure 6 , a plurality of mounting holes 5 are evenly formed at the bottom of the pad 202, and a ball 6 is rollingly mounted in the mounting hole 5, and the ball 6 contacts the top of the base 1, wherein the maximum depth of the mounting hole 5 is greater than the radius of the ball 6 and less than the diameter of the ball 6, and this structural design allows the ball 6 to rotate in the mounting hole 5 without falling off from the mounting hole 5. The design of the mounting hole 5 and the ball 6 reduces the friction resistance when the column 201 rotates, making the rotation smoother and further improving the spraying efficiency.

[0037] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
