Description

Technical Field

[0001] The present invention relates to the field of spraying technology, in particular to a spraying device for automobile parts. Background Art

[0002] Auto parts face various harsh environments during use, such as moisture, salt, dust, etc. The sprayed paint layer can form a protective film on the surface of the parts, isolating them from corrosive factors in the external environment, effectively extending the service life of the parts, and greatly reducing rust. The paint is generally liquid or semi-liquid when it is first sprayed onto the surface of the parts. Only after air drying, the solvent in it evaporates, and the resin and other components undergo cross-linking reactions to complete solidification, can it become stable and have corresponding performance.

[0003] At present, in the existing technology, parts are usually taken to a drying place for air drying after spraying. Since the surface coating of the parts is not dry, they may be damaged by external forces such as collision, friction, and vibration, resulting in scratches, peeling, etc., which affects the spraying effect. In addition, taking and transferring parts requires a certain amount of manpower and time, which makes the entire production process discontinuous, increases the connection time between production links, slows down the production progress, and is not conducive to efficient production.

[0015] Compared with the prior art, the present invention provides an automobile parts spraying equipment with the following beneficial effects: 1. The automobile parts spraying equipment gradually squeezes the material in the first cylinder through the movement of the placement table, so that the material is transported into the first spraying pipe through the first delivery pipe and sprayed out through the first spray head to realize the spraying operation of the automobile parts.

[0017] 3. The automotive parts spraying equipment can release bubbles to the bottom of the spray box through the first exhaust pipe and the second exhaust pipe, forming an airflow at the bottom of the spray box, so that the spray material that was originally relatively static or had poor fluidity is stirred up, prompting the paint particles to collide and mix with each other, which helps to better evenly distribute materials of different components and different batches, and improve the overall mixing effect. Secondly, the air jet can drive the air in the spray box to form a circular flow, avoid the situation of air stagnation in local areas, reduce the phenomenon of local accumulation of materials, make the material concentration at different positions in the box more consistent, further improve the mixing uniformity, and improve the material utilization rate.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0022] Example 1: Reference Figures 1-8 , an automobile parts spraying equipment, including a work box 1, and also includes a placement table 2 slidably arranged in the work box 1, two upper surfaces of both sides of the placement table 2 are provided with two columns 201, and the columns 201 are provided with hooks 202 and support members 203; and a first cylinder 3 and a second cylinder 301 fixedly arranged in the work box 1, the first cylinder 3 and the second cylinder 301 are respectively arranged on both sides of the placement table 2; there are also two groups of first spraying pipes 308 and two groups of second spraying pipes respectively arranged on both sides of the placement table 2 Tube 311, a first spray head 309 is provided on the first spray tube 308, a second spray head 312 is provided on the second spray tube 311, a first delivery pipe 314 is provided at one end of the first cylinder 3 and the second cylinder 301 close to the inner wall of the working box 1, and the first delivery pipe 314 is respectively connected to the two groups of first spray tubes 308, and a second delivery pipe 315 is provided at one end of the first cylinder 3 and the second cylinder 301 away from the inner wall of the working box 1, and the second delivery pipe 315 is respectively connected to the two groups of second spray tubes 311.

[0023] In this embodiment, when in use, the automobile parts that need to be sprayed are first hung on the hook 202. The support member 203 can support the bottom of the parts to keep them in a vertical state, thereby facilitating subsequent spraying. During operation, the placement table 2 is controlled to move, thereby driving the automobile parts to move, and then the spraying operation is performed through the first spray pipe 308.

[0024] It should be specifically explained that the present application is provided with a first cylinder 3 and a second cylinder 301, which can be respectively used for spraying two groups of parts at the same time. Specifically, in the initial state, the first cylinder 3 is filled with spraying material, and the second cylinder 301 is not filled with spraying material. As the placement table 2 moves, the material in the first cylinder 3 will be gradually squeezed, so that it is transported into the first spraying pipe 308 through the first conveying pipe 314, and then the spraying material is sprayed out through the first spray head 309 to realize the spraying operation of the automotive parts. During this process, the second cylinder 301 will gradually extract the spraying material. When the placement table 2 moves to the other end of the working box 1, the spraying material in the first cylinder 3 will be completely sprayed, and the second cylinder 301 will be filled with material. At this time, the placement table 2 is controlled to move in the opposite direction, that is, the placement table 2 is controlled to reset, and then the spraying material in the second cylinder 301 can be squeezed to spray the parts at the other end of the placement table 2.

[0025] The first piston 302 is slidably connected to the first cylinder 3 and the second cylinder 301 . The first piston 302 is provided with a connecting rod 303 . The end of the connecting rod 303 away from the first piston 302 is fixedly connected to a push plate 304 . A special-shaped plate 206 is fixedly connected between the two push plates 304 .

[0026] It should be noted that when the material in the first cylinder 3 is squeezed and sprayed, the material on the right side of the first piston 302 in the first cylinder 3 will become less and less. At the same time, the first cylinder 3 will synchronously extract gas to make it enter the space on the left side of the first piston 302 in the first cylinder 3. After the first cylinder 3 completes spraying, when the placement table 2 is reset, the gas on the left side of the first piston 302 will be squeezed by the first piston 302, so that it will be discharged through the second delivery pipe 315, and then enter the second spraying pipe 311 and be discharged from the second spray head 312. The gas is used to air-dry the parts that have just been sprayed, so that the paint can solidify quickly. In addition, while the air-drying operation is in progress, the first piston 302 will continue to extract the spraying material to make it enter the right side of the first piston 302, so as to repeat this process to achieve a rapid spraying effect, and the second cylinder 301 on the other side of the placement table 2 is also performing the same work, thereby improving work efficiency.

[0027] Example 2: Reference Figure 2-Figure 5, an automobile parts spraying equipment, including a work box 1, and also including a placement table 2 slidably arranged in the work box 1, two columns 201 are provided on the upper surfaces of both sides of the placement table 2, and the columns 201 are provided with hooks 202 and supports 203; and a first cylinder 3 and a second cylinder 301 fixedly arranged in the work box 1, the first cylinder 3 and the second cylinder 301 are respectively arranged on both sides of the placement table 2; there are also two groups of first spraying pipes 308 and two groups of second spraying pipes 311 respectively arranged on both sides of the placement table 2, the first spraying pipe 308 is provided with a first spray head 309, the second spraying pipe 311 is provided with a second spray head 312, the first cylinder A first delivery pipe 314 is provided at one end of the cylinder 3 and the second cylinder 301 close to the inner wall of the working box 1, and the first delivery pipe 314 is respectively connected to the two groups of first spraying pipes 308, and a second delivery pipe 315 is provided at one end of the first cylinder 3 and the second cylinder 301 away from the inner wall of the working box 1, and the second delivery pipe 315 is respectively connected to the two groups of second spraying pipes 311; a first piston 302 is slidably connected in the first cylinder 3 and the second cylinder 301, and a connecting rod 303 is provided on the first piston 302, and the connecting rod 303 is fixedly connected to a push plate 304 at one end away from the first piston 302, and a special-shaped plate 206 is fixedly connected between the two push plates 304.

[0028] Baffles 204 are fixedly connected to both sides of the placement table 2, and a guide rod 205 is fixedly connected to the working box 1. The baffles 204 are slidably connected to the guide rod 205, and the two push plates 304 are respectively attached to the outer surfaces of the two baffles 204 on one side that is close to each other.

[0029] A support plate 305 is fixedly connected to the outer walls of the first cylinder 3 and the second cylinder 301, a fixed plate 306 is fixedly connected to the support plate 305, a first fixed block 307 and a second fixed block 310 are provided on the fixed plate 306, a first spraying pipe 308 is arranged on the first fixed block 307, and a second spraying pipe 311 is arranged on the second fixed block 310, and a shield plate 316 is provided on the first fixed block 307 and the second fixed block 310. The shield plate 316 can prevent the material sprayed from the first spray head 309 from being sprayed on the guide rod 205, thereby not affecting the normal movement of the placement table 2.

[0030] The first delivery pipe 314 is connected to the first fixed block 307, the second delivery pipe 315 is connected to the second fixed block 310, the first fixed block 307 is provided with a first pipeline connected to the first delivery pipe 314 and the first spray pipe 308, the second fixed block 310 is provided with a second pipeline connected to the second delivery pipe 315 and the second spray pipe 311, and an air intake pipe 317 is provided on one end of the first cylinder 3 and the second cylinder 301 close to the support plate 305.

[0031] In this embodiment, when the placement table 2 moves, it drives the baffle 204 fixedly connected thereto to move, so that the baffle 204 pushes the push plate 304 located on one side of the first cylinder 3 to move, thereby pushing the connecting rod 303 to move, driving the first piston 302 to move in the first cylinder 3, thereby squeezing the spraying material, so that it passes through the first delivery pipe 314 into the first spraying pipe 308, and then is sprayed out through the first spraying head 309; when the push plate 304 located on one side of the first cylinder 3 moves, that is, when the push plate 304 located at the front end moves, it can pass through the The shaped plate 206 drives the push plate 304 on the other side of the placement table 2 to move, thereby driving the second cylinder 301 to start working, and the two push plates 304 are respectively attached to the outer surfaces of the two baffles 204 on the side close to each other, that is, when the placement table 2 moves to the right, the front baffle 204 will drive the push plate 304 to move, and when the placement table 2 is reset and moves to the left, the rear baffle 204 will drive the push plate 304 to continue to move synchronously. The set special-shaped plate 206 can connect the two push plates 304, thereby realizing reciprocating work and improving work efficiency.

[0032] It should be noted that the positions of the baffle 204 and the push plate 304 will not interfere with the positions of the first fixed block 307 and the second fixed block 310, which can ensure the normal movement of the baffle 204 and the push plate 304. The provided air intake pipe 317 can facilitate the air intake of the first cylinder 3 and the second cylinder 301, thereby realizing the subsequent air drying operation, and a one-way valve is also provided on the air intake pipe 317 to prevent gas leakage from the air intake pipe 317.

[0033] Example 3: Reference Figure 2-Figure 8 , a spraying equipment for automobile parts, is basically the same as that of Example 2. Furthermore, two spray boxes 4 are further provided in the working box 1, and a partition 401 is provided in the spray box 4. The partition 401 divides the spray box 4 into a drawing area 402 and a stirring area 403. The first cylinder 3 and the second cylinder 301 are both provided with a drawing pipe 313, and the drawing pipes 313 on the first cylinder 3 and the second cylinder 301 are respectively connected to the drawing areas 402 of the two spray boxes 4.

[0034] A third cylinder 5 is fixedly installed in the spray box 4, and a second piston 501 is provided in the third cylinder 5. A thick rod 502 is provided on the outer wall of the second piston 501, and a thin rod 504 is slidably connected to the thick rod 502. The end of the thin rod 504 away from the thick rod 502 is fixedly connected to a fixed rod 505, and a circular plate 506 is provided on the fixed rod 505 to abut against the push plate 304.

[0035] An exhaust pipe 6 is provided on the top outer wall of the third cylinder 5, and a first exhaust pipe 601 and multiple second exhaust pipes 602 are provided on the bottom of the third cylinder 5. The first exhaust pipe 601 is provided with multiple exhaust ports 603, and the exhaust pipe 6, the first exhaust pipe 601 and the second exhaust pipe 602 are all provided with a one-way valve.

[0036] In this embodiment, when the placement table 2 moves to the right, the material in the first cylinder 3 is compressed for spraying, and the second cylinder 301 is simultaneously drawn out of the material. In addition, since the movement of the placement table 2 drives the baffle 204 and the push plate 304 to move, the circular plate 506 and the fixed rod 505 are also pushed to move, and then the second piston 501 is driven to move by the thin rod 504 and the thick rod 502, so that the second piston 501 squeezes the gas in the third cylinder 5, and discharges it to the bottom of the spray box 4 through the first exhaust pipe 601 and the second exhaust pipe 602, so that the spray Bubbles are generated at the bottom of the coating box 4, and airflow is formed at the bottom of the spray box 4, which stirs up the spray material that was originally relatively static or had poor fluidity, prompting the paint particles to collide and mix with each other, which helps to better evenly distribute materials of different components and different batches, and improve the overall mixing effect. Secondly, the air jet can drive the air in the spray box 4 to form a circulating flow, avoid the situation of air stagnation in local areas, reduce the phenomenon of local accumulation of materials, and make the material concentration at different positions in the box more consistent, further improve the mixing uniformity, and improve material utilization.

[0037] Moreover, the thin rod 504 can slide on the thick rod 502, which increases a certain degree of cushioning and prevents the push plate 304 from continuously pressing the thick rod 502 to form a jam, making it convenient to use.

[0038] It should also be noted that the spray box 4 is divided into an extraction zone 402 and a stirring zone 403 by a partition 401. The extraction zone 402 is relatively calm. When the placement table 2 needs to be moved to the left to reset, the first cylinder 3 will extract the spray material into the extraction zone 402 to avoid bubbles being extracted into the first cylinder 3 and affecting the spraying effect. When the spray material in the extraction zone 402 is reduced, the stirred material in the stirring zone 403 can enter the extraction zone 402 through the channel between the bottom of the partition 401 and the spray box 4, thereby facilitating recycling.

[0039] A first spring 503 is sleeved on the outer wall of the thick rod 502 , and the first spring 503 is arranged between the second piston 501 and the inner wall of the third cylinder 5 . A second spring 507 is provided between the fixed rod 505 and the thick rod 502 , and the second spring 507 is sleeved on the outer wall of the thin rod 504 .

[0040] When the placement table 2 moves to the right, the first spring 503 will be stretched. When the placement table 2 is reset to the left, the first spring 503 will drive the second piston 501 to automatically reset, so that the third cylinder 5 extracts gas through the exhaust pipe 6 and allows it to enter the third cylinder 5. When the placement table 2 moves to the right again, the jet stirring effect can continue to be achieved, and the exhaust pipe 6, the first exhaust pipe 601 and the second exhaust pipe 602 are all provided with a one-way valve, which can better realize the jet operation, and an air port is also provided on the outer wall of the third cylinder 5 to facilitate the air intake on the left side of the second piston 501.

[0041] A stepper motor 101 is provided on the outer wall of the work box 1, and a threaded rod 102 is provided at the output end of the stepper motor 101. The placement table 2 is threadedly connected to the threaded rod 102. A limit rod 103 is also provided inside the work box 1, and the placement table 2 is slidably connected to the limit rod 103. A vertical plate 104 is fixedly connected to the inner surface of the bottom of the work box 1.

[0042] In the present invention, starting the stepper motor 101 can drive the threaded rod 102 to rotate, and then drive the placement table 2 to move to realize subsequent operations. The limit rod 103 can make the placement table 2 move more smoothly. The special-shaped plate 206 moves at the bottom of the placement table 2 and will not interfere with the placement table 2. The stepper motor 101 can realize forward and reverse operations. When rotating forward, the placement table 2 moves to the right. When the stepper motor 101 reverses, the placement table 2 can move to the left and reset.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
