Description

Technical Field

[0001] The utility model relates to the technical field of flat processing, in particular to a spraying device for the surface of a shell. Background Art

[0002] The tablet computer is a new member of the PC family. Its appearance is similar to that of a notebook computer, but it is not a pure notebook computer. It can be called a condensed version of a notebook computer. For product diversification, the back shell of the tablet computer is generally sprayed with a variety of different colors to meet the preferences of different users. Therefore, during the processing, a spraying device is generally used to coat the back shell of the tablet.

[0003] The prior art generally sprays by placing the shell below the spraying mechanism, and then taking out the shell after spraying is completed, and repeating this process. For example, a spraying device for processing a tablet computer shell disclosed in Chinese Patent Publication No. "CN219647850U" includes a workbench, a bracket is installed on the workbench, two hydraulic cylinders are installed at the top end inside the bracket, an isolation box is installed at the bottom of the hydraulic cylinder, and a spraying mechanism extending into the isolation box is installed on the bracket.

[0004] When spraying with a traditional spraying structure, its efficiency is low, and it is difficult to achieve reciprocating continuous operation. At the same time, because the surface of the shell has paint after spraying, it is not convenient for users to pick up after being placed on a flat surface. Based on this, we propose a spraying device for the surface of a shell. Summary of the Utility Model

Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Referring to Figures 1-3 An embodiment of the present invention discloses a spraying device for the surface of a housing. The device includes a machine table 1. A transfer mechanism 2 is fixedly installed on the top of the machine table 1. The transfer mechanism 2 can adopt a three-axis moving mechanism. Specifically, the three-directional movement drive can be realized through three interconnected ball screw assemblies. This means is a prior art and will not be elaborated here. A spraying mechanism 3 is fixedly installed at the output end of the transfer mechanism 2. The spraying mechanism 3 is connected to a material tank through a pump for spraying the flat housing.

[0022] Among them, a turntable 5 is rotatably connected to the top of the machine table 1 through a driving member 4. A plurality of mold bases 6 are circumferentially distributed on the upper surface of the turntable 5. During operation, the flat housing can be sleeved on the mold base 6 to achieve comprehensive spraying of the back end of the housing. A pushing mechanism 7 is further provided in the mold base 6. The pushing mechanism 7 is used to push the housing on the mold base 6 upward.

[0023] In some embodiments, the driving member 4 is a motor fixedly installed on the machine table 1. The motor is preferably a servo motor to achieve precise control of the rotation angle of the turntable 5. The shaft end of the motor is fixedly connected to the turntable 5.

[0024] Further, the pushing mechanism 7 includes a push plate 71. In this embodiment, the push plate 71 has an X-shaped structure. A groove for placing the push plate 71 is provided on the mold base 6. Obviously, the groove should also be set in an X-shaped structure. Among them, a push rod 72 penetrating the turntable 5 is provided at the bottom of the push plate 71. A spring 73 is further provided between the push rod 72 and the turntable 5. A push block 74 for abutting against the push rod 72 is further installed on the top of the machine table 1.

[0025] Specifically, in the present invention, four of the above-mentioned mold bases 6 are provided, thus forming four regions: a loading section, a processing section, a section to be unloaded, and an unloading section, which can realize continuous loading and spraying operations of the flat housing, greatly improving the spraying efficiency of the housing. In addition, those skilled in the art obviously know that the above-mentioned push block 74 should be provided below the unloading section. That is, during operation, when the turntable 5 rotates, the mold base 6 on the section to be unloaded moves above the push block 74. At this time, the push rod 72 in the mold base 6 contacts the push block 74, and thus moves upward to drive the push plate 71 to lift the housing, so as to realize the convenient taking of the housing.

[0026] On the basis of the above embodiments, a limiting protrusion 75 is further provided on the outer side of the ejector rod 72. The spring 73 is placed between the limiting protrusion 75 and the turntable 5. The ejector rod 72 is threadedly connected to the push plate 71. That is to say, in the embodiments of the present invention, the heights of the above-mentioned ejector rod 72 and the push plate 71 can be adjusted and are detachable. The user can adjust the distance between the limiting protrusion 75 and the turntable 5. When the side length increases, the length of the ejector rod 72 that can push up the push plate 71 increases, and vice versa. In this way, the adjustment of the jacking height of the outer shell can be realized, and at the same time, the ejector rod 72 and the push plate 71 can be disassembled, replaced and repaired.

[0027] In addition, a guiding inclined surface is provided on one side of the push block 74 in the present invention, and a roller is provided at the bottom end of the ejector rod 72.

[0028] It should be noted that, in order to adapt to flat plates of different models and sizes, two insertion rods 61 are further provided at the bottom of the mold base 6 in the present invention. The insertion rods 61 penetrate and extend to the bottom of the turntable 5. Among them, a spring pin assembly 62 is further embedded on the outer side of the insertion rods 61. When the mold base 6 needs to be replaced, first remove the push plate 71, and only press the pin end of the spring pin assembly 62 inward to make it retract. At this time, the mold base 6 can be pulled upward to be replaced.

[0029] In summary, the spraying method that adopts the cyclic rotation of the turntable 5 in the present invention can effectively improve the spraying efficiency of the flat plate outer shell. At the same time, a pushing mechanism 7 is further provided on the mold base 6 to realize pushing the outer shell upward after the spraying operation is completed, so that the user can take the outer shell from the inner side of the outer shell, avoiding scratching the sprayed coating on the surface of the outer shell, thereby further ensuring the product quality and processing convenience.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
