Abstract

This utility model provides an atomized coating treatment device for automotive plastic parts, relating to the field of spraying. It includes a frame and a platform controlled to move on the frame. The platform has a cross-section with a rack on it. It also includes a shaft seat fixing bracket and a shaft seat fixed by the bracket. The shaft seat is fitted into a main shaft, which extends outward from the cross-section. This utility model uses the movement of the platform on the frame to drive the rack to mesh with a gear, forcing the main shaft to rotate around its own axis. Simultaneously, spray guns on the two forks of the main shaft spray in the direction of the main shaft axis. When the automotive plastic part is fixed to this axis by a clamp, the linear movement of the platform and the rotational motion of the main shaft combine to form a composite motion, enabling the spray guns to uniformly and without dead angles cover the entire surface to be sprayed, significantly improving spraying uniformity and efficiency, especially suitable for complex curved plastic parts.

Description

Technical Field

[0001] This utility model relates to the field of spraying, and more particularly to an atomized coating treatment device for automotive plastic parts. Background Technology

[0002] In the field of automotive plastic parts painting, lifting spraying equipment is a widely used technology that can effectively complete the painting of conventional plastic parts such as front and rear bumpers. However, this equipment has significant limitations when handling plastic parts with special and complex shapes, such as irregularly shaped structural parts like the ring-shaped collar of an air conditioning vent. Due to features such as concave surfaces, multi-angle bends, or deep cavities on the workpiece surface, it is difficult for the atomized paint to evenly cover the entire collar surface in a single spraying process, easily resulting in defects such as uneven coating, missed spraying, or sagging. Although there are dedicated coating equipment designed for such special workpieces on the market, their overall cost of purchase, maintenance, and operation is high, making it difficult to promote on a large scale in conventional production. In view of this, to solve the problems of poor coating uniformity and high cost of dedicated equipment for the aforementioned special plastic parts, this paper proposes an improved spraying equipment, which is an innovative design based on the original lifting spraying equipment.

The bearing is fitted into a main shaft, and the main shaft extends outward from the cross section.

[0006] It also includes a gear installed on the main shaft that meshes with a rack. When the frame moves, the main shaft rotates in the axial direction. The main shaft has two branches extending outward. Both branches are equipped with bent rods. The bent rods are fastened to the spray gun whose spraying direction is in the direction of the main shaft axis.

[0007] Preferably, the automotive plastic parts are fixed by a clamp in the axial direction of the spindle and are within the spraying range of the spray gun.

[0008] Preferably, the distance between the spray gun and the automotive plastic parts is adjustable.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0024] Example 1

[0025] This embodiment presents an atomized coating treatment device for automotive plastic parts. Please refer to [link / reference]. Figures 1-3 The device includes a frame 3 and a base 2 connected to its bottom. A control console 1 is located behind the frame 3. A synchronous belt support 16 is located at the top of the frame 3. A motor 17 is installed inside the base 2. A synchronous belt 15 is fitted between the synchronous belt support 16 and the output end of the motor 17. Two parallel limiting rods 4 are installed inside the frame 3. Slider blocks 6, which are fixedly connected to a platform 7, are mounted on the limiting rods 4. The synchronous belt 15 is also connected to the platform 7, allowing the motor 17 to drive the platform 7 to move relative to the frame 3 along the limiting rods 4 via the synchronous belt 15 when the motor 17 is running. Please refer to [link to relevant documentation]. Figure 1 The test bench 7 has two vertical sections. It is important to note that the rack 8 is fixedly mounted on only one section. The bearing holder 5 is fixed to the side of the frame 3, and a bearing holder 18 is fixed thereon. The main shaft 9 is rotatably fitted into the bearing holder 18 and extends horizontally outward from the cross-section. A gear 10 is mounted on the inner section of the main shaft 9. This gear 10 meshes with the rack 8, so that when the test bench 7 moves, the gear 10 drives the main shaft 9 to rotate around its own axis. Please continue reading. Figure 1 The extended end of the main shaft 9 has two symmetrical branches. Each branch end is equipped with a bent rod 11. The bent rod 11 has a fastener 12. The fastener 12 has two spatially misaligned channels. The first channel is fitted with the bent rod 11, and the second channel is equipped with a spray gun extension rod 13. The end of the spray gun extension rod 13 is connected to a spray gun 14 whose spraying direction is in the direction of the axis of the main shaft 9.

[0026] In this embodiment, the automotive plastic part specifically refers to a ring-shaped plastic part. Otherwise, the automotive plastic part is fixed by a clamp along the axial direction of the main shaft 9 and is within the spraying coverage area of ​​the spray gun 14. In this embodiment, the distance between the spray gun 14 and the workpiece is adjusted as follows: the second channel of the fastener 12 is designed to expand and contract during the tightening of the screw and nut. By tightening, the clamping force of the channel on the spray gun extension rod 13 is changed, allowing the spray gun extension rod 13 to move relative to the second channel and be tightened after movement. Similarly, the first channel can also expand and contract during the tightening of the screw and nut, allowing the fastener 12 to move relative to the bent rod 11 and be tightened after movement.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
