Description

Technical Field

[0001] This utility model relates to the field of sheet metal spraying technology, specifically to a sheet metal spraying device. Background Technology

[0002] Sheet metal processing is a comprehensive cold processing technology for thin metal sheets, including shearing, punching, bending, riveting, and splicing. Sheet metal has the characteristics of light weight, high strength, electrical conductivity, low cost, and good mass production performance. It has been widely used in the fields of electronics, communications, automotive industry, and medical devices. In order to protect the substrate from corrosion and wear and to give it an aesthetic appearance, spraying is a crucial step in the post-processing of sheet metal parts.

[0003] A search revealed Chinese patent CN222678465U, which discloses a spraying device for sheet metal parts. The device includes a fixed frame with a paint tank at the bottom. Spray guns are connected to both sides of the paint tank via pipes. This invention can stably hold sheet metal parts of different shapes and sizes for spraying. During spraying, it can also absorb paint molecules floating in the air on both sides of the fixed frame, thereby purifying the air. Its overall design is ingenious, flexible and convenient to use, and has good applicability and practicality.

[0004] Similar to existing technologies, fixed spraying methods are typically used. However, since the housing of a laser cutting machine is assembled from multiple sheet metal parts, and the paint cannot quickly form a film after spraying, operators often need to wait for the paint surface to partially cure before manually removing, flipping, and re-fixing the parts for spraying the other side. This process is not only cumbersome and labor-intensive, but also significantly reduces the overall efficiency of the spraying operation. It also increases the risk of the paint surface being damaged or contaminated during handling. Based on this, a sheet metal spraying device is proposed to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a sheet metal spraying device to solve the problem that after sheet metal parts are sprayed, the paint cannot form a film quickly. Operators often need to wait for the paint surface to initially cure before manually removing, flipping and re-fixing the sheet metal parts in order to spray the other side. This process is not only cumbersome and labor-intensive, but also significantly reduces the overall efficiency of the spraying operation. It also increases the risk of the paint surface being damaged or contaminated during transportation.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a sheet metal spraying device, including a spraying table and sheet metal parts; The upper surface of the spraying station is symmetrically provided with two load-bearing plates. A fixing mechanism for fixing sheet metal parts is provided on one side of the two load-bearing plates. The same top plate is provided above the two load-bearing plates. A spraying mechanism for spraying paint is provided on the upper surface of the top plate. The fixing mechanism includes a rotating shaft disposed on one side of two load-bearing plates, a square frame disposed between the two rotating shafts on opposite sides, a motor for driving the rotating shaft to rotate, and multiple connecting parts disposed on the square frame. The rotating shaft is rotatably connected to the load-bearing plate via a bearing. The motor is fixed on the right side of the right load-bearing plate, and its output shaft passes through and extends to the left side of the right load-bearing plate and is fixed to the rotating shaft. The spraying mechanism includes a paint tank mounted on the top plate, a feed box fixed to the lower surface of the top plate, and several atomizing nozzles connected to the feed box.

[0007] The above technical solution allows the sheet metal part to be fixed to the square frame on all four sides by multiple connecting parts, providing a stable clamping effect. In conjunction with the motor and rotating shaft, the sheet metal part can be flipped after being painted on one side, allowing for painting on the other side. This not only facilitates the installation of the sheet metal part but also enables automated double-sided painting without manual intervention, significantly improving painting efficiency.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the connector includes a movable plate, and two sliding holes for sliding the movable plate are provided on each of the four sides of the square frame. Multiple threaded holes are provided on the movable plate, and two through threaded rods extending to the lower side of the square frame are threadedly connected to each of the four sides of the square frame.

[0010] Through the above technical solution, the movable clamp can move within the sliding hole, and the threaded holes on it can be flexibly aligned with the optimal force points on the edges of sheet metal parts of different sizes, thus achieving adaptability to sheet metal parts of various specifications.

[0011] Furthermore, the movable plate has an L-shaped cross-section, and the dimension of the movable plate on the side away from the square frame is larger than the dimension of the sliding hole; the threaded hole is threadedly connected to the screw.

[0012] The above technical solution allows the L-shaped design to be inserted into the side of the sheet metal part, improving the stability of the sheet metal part and preventing the movable plate from detaching from the sliding hole.

[0013] Furthermore, the connector also includes a tightening block, which is threadedly connected to the other end of the screw.

[0014] The above technical solution ensures that the position of the screw on the square frame remains unchanged, thus improving the stability of the connection between the sheet metal parts and the square frame.

[0015] Furthermore, electric push rods are fixed to the top of the opposite sides of the two load-bearing plates, and a movable plate is provided at the top of the inner cavity of the load-bearing plate. The upper surface of the movable plate and the piston rod of the electric push rod are both fixed to the top plate.

[0016] The above technical solution allows the moving plate to be raised within the load-bearing plate by moving the electric push rod piston rod, thereby raising the height of the top plate and adjusting the distance between the atomizing nozzle and the sheet metal parts.

[0017] Furthermore, circular locking blocks are provided on both the left and right sides of the movable plate, and limiting holes for the locking blocks to slide are provided on the load-bearing plate.

[0018] The above technical solution allows the locking blocks and limiting holes to limit the distance the moving plate travels, preventing it from separating from the load-bearing plate.

[0019] Furthermore, electromagnetic control valves are provided on both the left and right sides of the paint tank, and the other end of the electromagnetic control valve is connected to a guide pipe, the other end of which is connected to the inner cavity of the feed box.

[0020] Through the above technical solution, the electromagnetic control valve can be used to control the paint in the paint tank to enter the feed box through the guide pipe, and complete the spraying of the paint.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. The multiple connecting parts can fix the four sides of the sheet metal part to the square frame, providing a stable clamping for the four sides of the sheet metal part. In addition, with the cooperation between the motor and the rotating shaft, the sheet metal part can be flipped after one side is sprayed, so that the other side of the sheet metal part can be sprayed. This not only facilitates the installation of the sheet metal part, but also realizes the automated spraying operation of the sheet metal part on both sides without manual intervention, which significantly improves the spraying efficiency. 2. During the sheet metal spraying process, the electric push rod can adjust the distance between the atomizing nozzle and the sheet metal as needed, ensuring that the optimal spraying range is always maintained when spraying special structures such as grooves and edges, effectively eliminating spraying blind spots, avoiding missed spraying or over-spraying, significantly improving the uniformity and consistency of coating quality, and also greatly reducing paint waste.

[0024] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0026] Example: Reference Figure 1 and Figure 2 A sheet metal spraying device includes a spraying table 1 and a sheet metal part 2; two load-bearing plates 3 are symmetrically arranged on the upper surface of the spraying table 1, and a fixing mechanism 4 for fixing the sheet metal part 2 is provided on one side opposite to the two load-bearing plates 3. A top plate 5 is provided above the two load-bearing plates 3, and a spraying mechanism 6 for spraying paint is provided on the upper surface of the top plate 5.

[0027] refer to Figures 2-5The fixing mechanism 4 includes a rotating shaft 41 disposed on one side of the two load-bearing plates 3, a square frame 42 disposed between the two rotating shafts 41 on one side of the two rotating shafts 41, a motor 43 for driving the rotating shaft 41 to rotate, and multiple connecting parts disposed on the square frame 42. The rotating shaft 41 is rotatably connected to the load-bearing plate 3 through a bearing. The motor 43 is fixed on the right side of the right load-bearing plate 3 and its output shaft passes through and extends to the left side of the right load-bearing plate 3 and is fixed to the rotating shaft 41. The cooperation between the motor 43 and the rotating shaft 41 allows the sheet metal part 2 to be flipped after one side is painted, so that the other side of the sheet metal part 2 can be painted, realizing the automated painting operation of the double sides of the sheet metal part 2.

[0028] In this embodiment, the connector includes a movable plate 44. Two sliding holes 45 are provided on each of the four sides of the square frame 42 for the movable plate 44 to slide. Multiple threaded holes 46 are provided on the movable plate 44. Two through threaded holes 46 and extending to the lower side of the square frame 42 are threadedly connected to each of the four sides of the square frame 42.

[0029] The movable plate 44 has an L-shaped cross-section, and the dimension of the movable plate 44 on the side away from the square frame 42 is larger than the dimension of the sliding hole 45; the threaded hole 46 is threadedly connected to the screw 47.

[0030] In addition, the connector also includes a tightening block 48, which is threaded to the other end of the screw 47. The tightening block 48 can improve the connection strength between the screw 47 and the square frame 42, and further improve the stability of the fixation between the movable plate 44 and the square frame 42, thereby making the sheet metal part 2 have good fixation stability.

[0031] In use, by placing the sheet metal part 2 on the square frame 42 and adjusting the horizontal position of the movable plate 44 until the movable plate 44 is inserted into the edge of the sheet metal part 2, the screw 47 can be screwed into the square frame 42 and passed through the threaded hole 46 on the movable plate 44. Then, the tightening block 48 is screwed into the other end of the screw 47, which further improves the connection strength between the square frame 42 and the screw 47. Then, one side of the sheet metal part 2 can be sprayed by the spraying mechanism 6. By starting the motor 43, the output shaft of the motor 43 rotates and drives the rotating shaft 41 to rotate, thereby making the square frame 42 rotate. The rotation of the square frame 42 can make the sheet metal part 2 rotate, thereby allowing the surface of the sheet metal part 2 to be painted.

[0032] refer to Figure 6 The spraying mechanism 6 includes a paint box 61 mounted on the top plate 5, a feed box 62 fixed to the lower surface of the top plate 5, and a plurality of atomizing nozzles 63 connected to the feed box 62.

[0033] The paint tank 61 is equipped with electromagnetic control valves 64 on both the left and right sides. The other end of the electromagnetic control valve 64 is connected to a guide pipe 65, and the other end of the guide pipe 65 is connected to the inner cavity of the feed box 62. The operator can open and close the electromagnetic control valve 64 through the control system. By opening the electromagnetic control valve 64, the paint in the paint tank 61 can enter the inner cavity of the guide pipe 65 through the electromagnetic control valve 64 and then enter under the guidance of the guide pipe 65.

[0034] refer to Figure 3 and Figure 7 Electric push rods 71 ​​are fixed to the top of the two load-bearing plates 3 on opposite sides. A movable plate 72 is provided on the top of the inner cavity of the load-bearing plate 3. The upper surface of the movable plate 72 and the piston rod of the electric push rod 71 are both fixed to the top plate 5.

[0035] The movable plate 72 is provided with circular locking blocks 73 on both the left and right sides. The load-bearing plate 3 is provided with limiting holes 74 for the locking blocks 73 to slide. The limiting holes 74 surround the locking blocks 73, forming a physical limit, which can prevent the movable plate 72 from accidentally falling off during operation and enhance reliability.

[0036] In use, by activating the electric push rod 71, the piston rod of the electric push rod 71 extends or retracts, and the top plate 5 can move linearly under the action of the piston rod. At this time, the moving plate 72 moves with the top plate 5. During the movement of the moving plate 72, the locking block 73 moves linearly in the inner cavity of the limiting hole 74, which can limit the movement position of the moving plate 72 in the inner cavity of the load-bearing plate 3. The feed box 62 and the atomizing nozzle 63 can move accordingly, thereby adjusting the distance between the atomizing nozzle 63 and the sheet metal part 2.

[0037] 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 within the protection scope of the present utility model.
