Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically to a spraying device for an organic protective coating on a magnesium alloy surface. Background Technology

[0002] Organic protective coating spraying on magnesium alloy surfaces is a process that uses spraying technology to form a uniform and dense organic protective layer on the surface of magnesium alloys to improve their corrosion resistance, wear resistance and other surface properties.

[0003] According to CN222112228U, a device for spraying an organic protective coating on a magnesium alloy surface is disclosed. This technology discloses "a device for spraying an organic protective coating on a magnesium alloy surface, including a spraying assembly for spraying a protective coating on a magnesium alloy. The spraying assembly includes a spraying box, a sealing door slidably connected to one side of the spraying box, an observation port on the sealing door, hydraulic rods symmetrically arranged inside the spraying box, a movable frame fixedly connected to the movable end of the hydraulic rods, a first sliding groove at the bottom of the movable frame, a first motor fixedly installed on one side of the movable frame, a first lead screw rotatably connected in the first sliding groove, and a first slider slidably connected in the first sliding groove." This technology has the following technical effects: "A third motor drives a third lead screw to rotate, thereby causing the third slider to move a clamping block. The magnesium alloy is fixed by the cooperation of the clamping block and the positioning groove. During fixing, the sides of the magnesium alloy are clamped and fixed, reducing the surface area occupied, thus allowing for better overall spraying of the magnesium alloy and reducing spraying dead corners."

[0004] Since the above solutions rely on manual labor or additional equipment to remove the coated workpieces, if the workpieces are not fully cured when they are removed, workers may come into direct contact with the uncured organic coatings, posing a chemical hazard risk. In addition, introducing additional equipment (such as robotic arms) for workpiece removal will not only increase the complexity of the device but also lead to an increase in initial investment costs.

[0005] To address the shortcomings of existing technologies, this utility model provides a magnesium alloy surface organic protective coating spraying device, which features positioning and unloading of the workpiece through a positioning mechanism spraying device, thereby automating the workpiece, reducing manual operation, and improving processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnesium alloy surface organic protective coating spraying device, comprising a suspended conveyor and several uprights fixed on the suspended conveyor, wherein the suspended conveyor is equipped with a positioning mechanism for workpiece positioning, and the uprights are equipped with spraying components for workpiece spraying; the positioning mechanism includes:

[0007] A width adjustment component is installed on the overhead conveyor and used to adjust the positioning according to the width of the workpiece.

[0008] The positioning assembly includes a positioning frame mounted on the width adjustment assembly. A shaft seat is fixed to the outer wall of the positioning frame. A positioning seat is pivotally connected to the lower end of the positioning frame and is used to support the workpiece. An electric push rod is pivotally connected to the shaft seat and its output end is pivotally connected to the outer end of the positioning seat.

[0009] A length positioning component is mounted on the positioning component and used to adjust the positioning according to the length of the workpiece.

[0010] Preferably, the width adjustment component includes several equidistantly distributed connectors fixed on the traction chain in the overhead conveyor. Both ends of the connectors are fixed with threaded rods. The outer wall of the threaded rod is provided with a sliding groove.

[0015] This invention provides a device for spraying an organic protective coating on a magnesium alloy surface. Compared with the prior art, it has the following advantages:

[0016] 1. Before the workpiece is placed in, the positioning seat is in a vertical position. The workpiece can be placed from bottom to top between the two positioning frames in the positioning mechanism and positioned by the positioning head. Then, the output end of the electric push rod extends to drive the positioning seat to rotate to a horizontal position, thereby supporting the workpiece and achieving workpiece positioning.

[0017] 2. When the spraying is finished, the suspended conveyor moves the workpiece positioned on the positioning mechanism to directly above the inclined frame of the material plate. The positioning component releases the positioning of the workpiece, allowing it to fall onto the inclined frame of the material plate and be unloaded by rollers. Furthermore, a conveyor belt can be installed below the inclined frame of the material plate so that the unloaded workpiece can be transported to the next process via the conveyor belt.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a magnesium alloy surface organic protective coating spraying device, including a suspended conveyor 1 and several uprights 2 fixed on the suspended conveyor 1. The suspended conveyor 1 is provided with a positioning mechanism 3 for positioning the workpiece, and the uprights 2 are provided with spraying components 4 for spraying the workpiece. The positioning mechanism 3 includes:

[0025] Width adjustment component 31 is mounted on overhead conveyor 1 and used to adjust positioning according to workpiece width;

[0026] The positioning component 32 includes a positioning frame 321 disposed on the width adjustment component 31. A bearing 322 is fixed to the outer wall of the positioning frame 321. A positioning seat 323 is pivotally connected to the lower end of the positioning frame 321 and is used to support the workpiece. An electric push rod 324 is pivotally connected to the bearing 322 and its output end is pivotally connected to the outer end of the positioning seat 323.

[0027] The length positioning component 33 is disposed on the positioning component 32 and is used to adjust the positioning according to the length of the workpiece.

[0028] In this embodiment, before the workpiece is placed in, the positioning seat 323 is in a vertical state. The workpiece can be placed from bottom to top between the two positioning frames 321 in the positioning mechanism 3 and positioned by the positioning head 331. Then, the output end of the electric push rod 324 extends to drive the positioning seat 323 to rotate to a horizontal position, thereby supporting the workpiece and achieving workpiece positioning. When the spraying is finished and the workpiece is unloaded, the output end of the electric push rod 324 retracts to drive the positioning seat 323 to rotate to a vertical position, allowing the workpiece to fall out of the positioning mechanism 3. The positioning mechanism 3 realizes positioning and unloading, realizes workpiece automation, reduces manual operation, and improves processing efficiency.

[0029] Specifically, the width adjustment component 31 includes several equidistantly distributed connectors 311 fixed on the traction chain in the overhead conveyor 1. Both ends of the connectors 311 are fixed with threaded rods 312. The outer wall of the threaded rods 312 is provided with a sliding groove 313. A sliding sleeve 314 is slidably installed on the outside of the threaded rods 312 through the sliding groove 313. The positioning frame 321 is fixed to the bottom of the sliding sleeve 314. A knob sleeve 315 is rotatably installed on the outer wall of the sliding sleeve 314 and its inner wall is threadedly installed with the threaded rods 312.

[0030] In this embodiment, rotating the knob sleeve 315 causes the sliding sleeve 314 to move along the threaded rod 312, and at the same time, the sliding sleeve 314 also causes the positioning component 32 to move; thus, the distance between the two positioning components 32 can be adjusted to match the width of the workpiece.

[0031] Specifically, the length positioning component 33 includes a positioning head 331 that is slidably mounted on the positioning frame 321, and a knob head 332 is threadedly mounted on the outer wall of the positioning head 331.

[0032] In this embodiment, the height of the positioning head 331 on the positioning frame 321 can be adjusted according to the length of the workpiece, and the positioning head 331 can be fixed by rotating and tightening the knob head 332.

[0033] Specifically, a material plate inclined frame 5 is fixed below one end of the suspended conveyor 1, and several equally spaced rollers 6 are rotatably installed inside the material plate inclined frame 5.

[0034] In this embodiment, when the spraying is finished, the suspended conveyor 1 moves the workpiece positioned on the positioning mechanism 3 to directly above the material plate inclined frame 5. The positioning component 32 releases the positioning of the workpiece, allowing the workpiece to fall onto the material plate inclined frame 5 and be rolled off by the roller 6. Furthermore, a conveyor belt can be set below the material plate inclined frame 5 so that the unloaded workpiece can be transported to the next process via the conveyor belt.

[0035] Specifically, the spraying assembly 4 includes a bracket 41 fixed to the bottom of the outer end of the stand 2, and a conveying pipe 42 fixed to the lower ends of both sides of the bracket 41. Several spray nozzles 43 are installed on the conveying pipe 42.

[0036] In this embodiment, the conveying pipe 42 is connected to the feeding device, so that the paint can be sprayed out from the nozzle 43 through the conveying pipe 42, thereby spraying the front and back sides of the workpiece positioned on the positioning mechanism 3.

[0037] Specifically, the spacing between several uprights 2 is equal to the spacing between several positioning mechanisms 3.

[0038] In this embodiment, when the overhead conveyor 1 drives the positioning mechanism 3 to move, each positioning mechanism 3 can move to the spraying assembly 4 on each stand 2, so that the spraying assembly 4 can perform spraying processing with the workpiece positioned in the corresponding positioning mechanism 3.

[0039] The working principle and usage process of this utility model are as follows: First, before the workpiece is placed in, the positioning seat 323 is in a vertical state. The workpiece can be placed from bottom to top between the two positioning frames 321 in the positioning mechanism 3 and positioned by the positioning head 331. Then, the output end of the electric push rod 324 extends to drive the positioning seat 323 to rotate to a horizontal position, thereby bearing the workpiece and realizing the positioning of the workpiece.

[0040] Then, the workpiece positioned in the positioning mechanism 3 is moved to the spraying assembly 4 by the overhead conveyor 1, and connected to the feeding equipment through the conveying pipe 42, so that the paint can be sprayed out from the nozzle 43 through the conveying pipe 42, thereby spraying the front and back sides of the workpiece positioned on the positioning mechanism 3.

[0041] Finally, when the spraying is finished, the workpiece positioned in the positioning mechanism 3 is moved to the top of the material plate inclined frame 5 by the overhead conveyor 1. Then, the positioning seat 323 is rotated to vertical by the output end of the electric push rod 324, releasing the positioning of the workpiece. This allows the workpiece to fall from the positioning mechanism 3 onto the material plate inclined frame 5 and be rolled off by the roller 6. In addition, a conveyor belt can be set below the material plate inclined frame 5 so that the unloaded workpiece can be transported to the next process by the conveyor belt.
