AI Technical Summary
In existing spray painting equipment, when a robotic arm with a spray nozzle sprays computer casings, it is easy to miss some paint, and the amount of paint that can be sprayed at one time is limited, resulting in low efficiency.
The system employs a servo motor-driven square column and a reciprocating painting mechanism, combined with a positioning component. The servo motor drives the square column to rotate forward and backward, while the positioning component secures the back cover of the display. The reciprocating painting mechanism sprays paint when the display stops, achieving uniform coating.
It achieves uniform coating of the monitor back cover, avoids paint waste, and improves coating efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of display back cover manufacturing technology, specifically to a display back cover painting device. Background Technology
[0002] The back cover of a computer monitor is one of the more important computer components, serving to protect and store the screen and other components. During the manufacturing process, in order to increase its strength and durability, its outer surface needs to be painted.
[0003] Currently, most painting equipment uses robotic arms to carry spray heads to paint computer casings. The computer casing is placed on a clamping mechanism and reaches the spray head through a horizontal transmission mechanism. The spray head sprays the casing back and forth to achieve a uniform paint effect. However, the painting process takes place within the time it takes for the horizontal transmission mechanism to pass through, which can easily lead to missed areas. In addition, the number of computer casings that can be painted at one time is limited, resulting in low efficiency. Therefore, a monitor back casing painting device has been proposed to solve the above problems. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] The purpose of this invention is to address the problems in current painting equipment, which mostly uses robotic arms to carry spray heads to paint computer casings. The computer casing is placed on a clamping mechanism and reaches the spray head through a horizontal transmission mechanism. The spray head then sprays the casing back repeatedly to achieve a uniform paint effect. However, during the painting process, the spraying is carried out within the time it takes for the horizontal transmission mechanism to pass through, which can easily lead to missed areas. Furthermore, the number of computer casings that can be painted at one time is limited, resulting in low efficiency. Therefore, this invention proposes a monitor back casing painting device.
[0006] (II) Technical Solution
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0008] A display back cover painting device includes a worktable with four casters at the bottom. A servo motor is fixedly connected to the inner side of the worktable, and the output end of the servo motor extends through and above the worktable. A square column is fixedly connected to the top of the output end of the servo motor, and a reciprocating painting mechanism is provided on the square column. A positioning component for positioning the display back cover is provided at the top of the worktable.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Preferably, the positioning component includes fixed rods, and a plurality of fixed rods are fixedly connected to the top of the worktable. A base column is provided between each two adjacent fixed rods. The plurality of base columns are fixedly connected to the top of the worktable. A positioning column is fixedly connected to the top of the base column. A support plate is threadedly connected to the outer side of the positioning column. The ground of the support plate is in close contact with the top surface of the base column. The top of the plurality of fixed rods is fixedly connected to a connecting ring.
[0011] (III) Beneficial Effects
[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0013] This invention incorporates a servo motor, a square column, and a reciprocating spray painting mechanism. When the servo motor is activated, it drives the square column to rotate one revolution clockwise and then one revolution counterclockwise, repeating this process several times before stopping. During the rotation of the square column, it pauses for 10 seconds after each 90-degree rotation. During these 10-second pauses, the reciprocating spray painting mechanism moves upwards or downwards and continuously sprays paint. During the rotation of the square column, the reciprocating spray painting mechanism neither moves nor sprays paint, ensuring that the back cover of the display is fully coated without any waste.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] In the embodiments, by Figure 1 and Figure 2A display back cover painting device is provided, including a worktable 1, four casters 2 at the bottom of the worktable 1, a servo motor 3 fixedly connected to the inner side of the worktable 1, the output end of the servo motor 3 passing through and extending to the top of the worktable 1, a square column 4 fixedly connected to the top of the output end of the servo motor 3, a reciprocating painting mechanism 5 provided on the square column 4, and a positioning component 6 for positioning the display back cover provided at the top of the worktable 1.
[0019] With the above setup, the four monitor back covers are first placed in the positioning component 6, which is positioned precisely in the four cardinal directions (north, south, east, and west) of the square column 4. The positioning component 6 secures the monitor back covers. Then, the servo motor 3 is started, which drives the square column 4 to rotate one revolution clockwise and then one revolution counterclockwise, repeating this several times before stopping. During the rotation of the square column 4, it stops for 10 seconds after every 90 degrees of rotation. During these 10-second stops, the reciprocating spray painting mechanism 5 moves up or down and continuously sprays paint (the reciprocating spray painting mechanism 5 does not move or spray paint during the rotation of the square column 4), ensuring that all monitor back covers are painted. The worktable 1 can be moved as needed, using the four casters 2 to move to the target position. It should be noted that the reciprocating spray painting mechanism 5 is driven by an electric push rod. The spray painting mechanism is any device that can perform the painting operation using existing technology, which is common knowledge to those skilled in the art and will not be described in detail here. Furthermore, the above control process is controlled by a controller, and the code is pre-compiled by the staff.
[0020] Reference Figure 1 and Figure 2 The positioning component 6 includes a fixing rod 61. Several fixing rods 61 are fixedly connected to the top of the workbench 1. A base column 62 is provided between two adjacent fixing rods 61. Several base columns 62 are fixedly connected to the top of the workbench 1. A positioning column 63 is fixedly connected to the top of the base column 62. A support plate 64 is threaded to the outside of the positioning column 63. The ground of the support plate 64 is in close contact with the top surface of the base column 62. The top of several fixing rods 61 is fixedly connected to a connecting ring 65.
[0021] With the above structural setup, the monitor back cover is first placed above two adjacent support plates 64. The fixing rod 61 and the two positioning pins 63 can clamp the monitor back cover, thereby fixing it. After fixing the four monitor back covers in sequence, the four monitor back covers can be painted.
