Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically to an improved spraying device for processing computer casings. Background Technology

[0002] When manufacturing computer casings, they need to be painted. Currently, most computer casings are painted using an exposed painting method. The traditional painting method is to place the computer casing directly on the grid or support the casing by clamping it for painting.

[0003] A search revealed a Chinese patent that discloses a spraying device for processing tablet computer casings (publication number: CN219647850U). This patent places the tablet computer casing on a workbench under an isolation box for spraying.

[0004] After the existing equipment has finished spraying, the sprayed shell needs to be removed. Direct placement can scratch the sprayed paint when removing it, while clamping can cause the clamp to block the paint and prevent complete spraying. Therefore, those skilled in the art have proposed an improved spraying device for computer shell processing to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an improved spraying device for computer casing processing, which solves the problem in the prior art that it is inconvenient to remove the sprayed computer casing.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-6 An improved spraying apparatus for computer casing processing includes:

[0028] The housing 1 has a spray chamber inside, and a grid 103 is fixedly connected inside the spray chamber. A drain pipe 101 connected to the spray chamber is provided on one side of the housing 1. Water is provided inside the spray chamber below the grid 103. A transparent plate 102 is provided on the surface of the housing 1. A spraying mechanism 3 is provided on the inner top wall of the spray chamber.

[0029] Placement structure 2 is located above the grid 103 and is used to place the workpiece to be sprayed.

[0030] The placement structure 2 includes a sliding plate 202 slidably connected to the surface of the grille 103. The top of the sliding plate 202 is fixedly connected to evenly distributed mounting cylinders 203. The surface of the grille 103 is provided with a groove that communicates with the mounting cylinders 203. A connecting rod 204 is fixedly connected to one side of the sliding plate 202. A pull plate 201 is fixedly connected to the other end of the connecting rod 204. A support component 21 is detachably provided inside the mounting cylinder 203.

[0031] The spraying mechanism 3 is used for spraying paint. It mainly consists of a storage cylinder, an atomizing nozzle, a pump body, and an electric slide rail. The pump body is used to spray the paint stored inside the storage cylinder through the atomizing nozzle, and the electric slide rail is used to adjust the spraying position.

[0032] The grid 103 is designed to ensure that paint that exceeds the edge of the workpiece during the spraying process can pass through the grid 103 and enter below the grid 103, while the water inside the spraying chamber can improve the flow of water falling below the grid 103, making it easier to be discharged through the drain pipe 101.

[0033] The transparent panel 102 can slide up and down, and can block the opening of the spray booth during the spraying process, preventing paint particles from entering the outside.

[0034] By moving the pull plate 201, the sliding plate 202 can be driven to slide along the surface of the grid 103 under the action of the connecting rod 204, so as to adjust the position of the sliding plate 202.

[0035] Please see Figure 1-6 The support assembly 21 includes a mounting rod 2101. The lower end of the mounting rod 2101 extends through the mounting cylinder 203 and is hemispherical. The upper end of the mounting rod 2101 is fixedly connected to a mounting block 2102. Two symmetrically distributed connecting cylinders 2103 are fixedly connected to the surface of the mounting block 2102. A sliding plate 2104 is slidably connected to the inner wall of the connecting cylinder 2103. An adjusting rod 2106 is fixedly connected to the side of the sliding plate 2104 away from the mounting block 2102. A spring 2105 is fixedly connected between the other side of the sliding plate 2104 and the surface of the mounting block 2102.

[0036] The top of the mounting block 2102 is provided with a turntable 2107, and the bottom of the turntable 2107 is fixedly connected with a rotating column 2108. The other end of the rotating column 2108 is rotatably connected to the inner wall of the mounting block 2102. A connecting rope 2109 is fixedly connected to the surface of the sliding plate 2104. The other end of the connecting rope 2109 passes through the interior of the mounting block 2102 and is fixedly connected to the surface of the rotating column 2108.

[0037] The mounting rod 2101 can be inserted into the mounting cylinder 203, while the mounting block 2102 is blocked by the mounting cylinder 203 to achieve the effect of placing the mounting block 2102. At this time, the adjusting rod 2106 can be affected by the inner wall of the mounting cylinder 203 to limit the position of the mounting block 2102. During the process of placing the workpiece, i.e., the computer shell, by rotating the turntable 2107, the rotating column 2108 can be rotated to wind up the connecting rope 2109, so as to synchronously drive the two sliding plates 2104 to move closer to each other. At this time, the adjusting rod 2106 can be driven to retract into the connecting cylinder 2103. Then, the workpiece to be sprayed is placed on top of the mounting block 2102, and the turntable 2107 is released. At this time, the sliding plate 2104 can be reset under the action of the spring 2105. Thus, the adjusting rod 2106 can be reset and unfolded to support the workpiece from the inside, achieving the support effect of the workpiece, which is convenient for subsequent spraying by the spraying mechanism 3.

[0038] Please see Figure 1-6 The adjusting rod 2106 is fixedly connected to one end away from the mounting block 2102 with two symmetrically distributed connecting plates 2111. A support block 2110 is provided between the two connecting plates 2111. Two symmetrically distributed rotating shafts 2112 are fixedly connected to the surface of the support block 2110. The other end of the rotating shaft 2112 passes through the adjacent connecting plate 2111.

[0039] A spring 2113 is fixedly connected to the surface of the rotating shaft 2112, and the other end of the spring 2113 is fixedly connected to the inner wall of the connecting plate 2111.

[0040] During the resetting process of the adjusting rod 2106, the support block 2110 can first contact the inner wall of the workpiece. Under the obstruction of the inner wall of the workpiece, the support block 2110 can adaptively adjust along the shape of the inner wall of the workpiece. The setting of the rotating shaft 2112 allows the support block 2110 to rotate around the rotating shaft 2112 to facilitate adaptive adjustment. During the rotation, the spring 2113 can be tightened, and under the reaction force of the spring 2113, the support block 2110 can be tightly attached to the inner wall of the workpiece, which improves the support effect on the workpiece and avoids the possibility of falling off during the spraying process. Since it is supported on the back side of the spraying surface of the workpiece, it will not affect the spraying of the workpiece.

[0041] Please see Figure 1-6 The surface of the housing 1 is provided with a through groove 2114 that communicates with the slide groove, and a guide block 2115 is fixedly connected to the inner wall of the through groove 2114.

[0042] When it is necessary to remove the coated workpiece, the sliding plate 202 can be moved by the pull plate 201 until the mounting rod 2101 moves into the through groove 2114. Due to the restriction of the mounting cylinder 203, the mounting rod 2101 is guided by the top surface of the guide block 2115 to gradually pass through the mounting cylinder 203. At this time, the part of the mounting rod 2101 that passes through the mounting cylinder 203 can be taken out, avoiding the direct removal of the workpiece and affecting the surface coating effect.

[0043] Working principle: Rotating the turntable 2107 causes the rotating column 2108 to rotate and wind up the connecting rope 2109, thereby synchronously driving the two sliding plates 2104 to move closer to each other. At this time, the adjusting rod 2106 can be driven to retract into the inside of the connecting cylinder 2103. Then, the workpiece to be sprayed is placed above the mounting block 2102, and the turntable 2107 is released. At this time, the sliding plate 2104 is driven to reset under the action of the spring 2105. Thus, the adjusting rod 2106 can be reset and unfolded to support the workpiece from the inside, achieving the workpiece support effect, which is convenient for subsequent spraying by the spraying mechanism 3. After the spraying is completed, the pull plate 201 drives the sliding plate 202 to move until the mounting rod 2101 moves into the inside of the through groove 2114. Due to the restriction of the mounting cylinder 203, the mounting rod 2101 is guided by the top surface of the guide block 2115 to gradually pass through the mounting cylinder 203. At this time, the part of the mounting rod 2101 that has passed through the mounting cylinder 203 can be picked up, avoiding the direct picking of the workpiece and affecting the surface spraying effect.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
