Description

Technical Field

[0001] This invention relates to the field of spraying technology, and more particularly to a spraying equipment for automotive parts. Background Technology

[0002] Automotive parts face various harsh environments during use, such as humidity, salt, and dust. 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. When the paint is first sprayed onto the surface of the parts, it is generally in a liquid or semi-liquid state. Only after air drying, allowing the solvents to evaporate and the resin and other components to undergo a cross-linking reaction to complete the curing process, can it form a stable structure with the corresponding properties.

[0003] Currently, in existing technologies, parts are usually taken to an air-drying area after spraying. However, since the coating on the surface of the parts is not dry, it 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. In view of this, the present invention is proposed. Summary of the Invention

[0016] Furthermore, a third cylinder is fixedly installed inside the spray box, and a second piston is installed inside the third cylinder. A thick rod is provided on the outer wall of the second piston, and a thin rod is slidably connected inside the thick rod.

[0017] Furthermore, a first spring is sleeved on the outer wall of the thick rod, and the first spring is disposed between the inner wall of the second piston and the third cylinder.

[0019] Preferably, the outer wall of the work box is provided with a stepper motor, the output end of the stepper motor is provided with a threaded rod, the placement platform is threadedly connected to the threaded rod, the work box is also provided with a limiting rod, the placement platform is slidably connected to the limiting rod, and a vertical plate is fixedly connected to the bottom inner surface of the work box.

[0020] Compared with the prior art, the present invention provides an automotive parts spraying equipment, which has the following beneficial effects:

[0021] 1. This automotive parts painting equipment, through the movement of the placement platform, gradually squeezes the material in the first cylinder, thereby conveying it through the first conveying pipe into the first spraying pipe and spraying it out through the first spraying head to achieve the painting operation of automotive parts. By controlling the placement platform to move in the opposite direction, it can start to squeeze the painting material in the second cylinder, so as to carry out the painting operation on the parts at the other end of the placement platform, so that the two sides can reciprocate the painting effect, further improving the work efficiency.

[0022] 2. In this automotive parts painting equipment, during the spraying process through the first cylinder, the material on the right side of the first piston in the first cylinder gradually decreases, while gas is extracted from the space on the left side of the first piston within the first cylinder. When the first cylinder finishes spraying and the placement platform resets, the gas on the left side of the first piston is squeezed out through the second spray head. This gas is used to air dry the freshly sprayed parts, allowing the paint to solidify quickly without needing to move the parts to another location for drying. This avoids damage such as scratches and peeling caused by external forces such as collisions, friction, and vibration, improving the spraying effect and efficiency, and ensuring production progress.

[0023] 3. This automotive parts spraying equipment releases air bubbles to the bottom of the spray box through the first and second exhaust pipes, creating an airflow at the bottom of the spray box. This agitates the previously relatively static or poorly flowing spraying materials, causing the paint particles to collide and mix. This helps to better and more evenly distribute materials of different components and batches, improving the overall mixing effect. Secondly, the air jet can drive the air inside the spray box to circulate, avoiding localized areas of poor air circulation and reducing the accumulation of materials in certain areas. This makes the material concentration in different locations within the box more consistent, further improving the mixing uniformity and increasing material utilization. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] Example 1: Refer to Figures 1-8 An automotive parts painting device includes a work box 1, a placement platform 2 slidably disposed within the work box 1, two columns 201 on each side of the upper surface of the placement platform 2, hooks 202 and support members 203 on the columns 201; a first cylinder 3 and a second cylinder 301 fixedly disposed within the work box 1, the first cylinder 3 and the second cylinder 301 respectively disposed on both sides of the placement platform 2; and two sets of first spray pipes 308 and two sets of second spray pipes respectively disposed on both sides of the placement platform 2. The first spray pipe 308 is equipped with a first spray head 309, and the second spray pipe 311 is equipped with a second spray head 312. The first cylinder 3 and the second cylinder 301 are equipped with a first conveying pipe 314 at the end near the inner wall of the working box 1. The first conveying pipe 314 is connected to the two sets of first spray pipes 308 respectively. The second conveying pipe 315 is equipped at the end of the first cylinder 3 and the second cylinder 301 away from the inner wall of the working box 1 respectively. The second conveying pipe 315 is connected to the two sets of second spray pipes 311 respectively.

[0036] In this embodiment, when in use, the car parts that need to be painted are first hung on the hook 202. The support 203 can support the bottom of the parts and keep them in a vertical state, which facilitates the subsequent painting. During operation, the placement platform 2 is controlled to move, thereby moving the car parts. Then, the painting operation is carried out through the first spray pipe 308.

[0037] It should be specifically noted that this application includes a first cylinder 3 and a second cylinder 301, which can be used to spray two sets of parts simultaneously. Specifically, in the initial state, the first cylinder 3 is filled with spraying material, while the second cylinder 301 is not filled with spraying material. As the placement platform 2 moves, the material in the first cylinder 3 is gradually squeezed, so that it is transported into the first spraying pipe 308 through the first conveying pipe 314. Then, the spraying material is sprayed out through the first spraying 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 platform 2 moves to the other end of the work 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, controlling the placement platform 2 to move in the opposite direction, that is, controlling the placement platform 2 to reset, can start squeezing the spraying material in the second cylinder 301 to spray the parts at the other end of the placement platform 2.

[0038] A first piston 302 is slidably connected inside both the first cylinder 3 and the second cylinder 301. A connecting rod 303 is provided on each of the first pistons 302. A push plate 304 is fixedly connected to the end of the connecting rod 303 away from the first piston 302. A shaped plate 206 is fixedly connected between the two push plates 304.

[0039] It should be further explained 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 gradually decrease. At the same time, the first cylinder 3 will simultaneously draw in gas, which will enter the space on the left side of the first piston 302. When the first cylinder 3 finishes spraying and the placement platform 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 conveying pipe 315 and then enter the second spraying pipe 311, and be discharged from the second spraying head 312. This gas is used to air dry the parts that have just been sprayed, so that the paint can solidify quickly. During the air drying operation, the first piston 302 will continue to draw in the sprayed material, which will enter the right side of the first piston 302. This process is repeated to achieve a rapid spraying effect. The second cylinder 301 on the other side of the placement platform 2 is also performing the same work, which improves work efficiency.

[0040] Example 2: Refer to Figures 2-5An automotive parts painting device includes a work box 1 and a placement platform 2 slidably disposed within the work box 1. Two columns 201 are provided on the upper surfaces of both sides of the placement platform 2, and hooks 202 and support members 203 are provided on the columns 201. A first cylinder 3 and a second cylinder 301 are fixedly disposed within the work box 1, respectively disposed on both sides of the placement platform 2. Two sets of first spray pipes 308 and two sets of second spray pipes 311 are also provided on both sides of the placement platform 2. The first spray pipes 308 are provided with first spray heads 309, and the second spray pipes 311 are provided with second spray heads 312. The first conveying pipe 314 is provided at the end of the first cylinder 3 and the second cylinder 301 near the inner wall of the working box 1. The first conveying pipe 314 is connected to the two sets of first spray pipes 308 respectively. The second conveying pipe 315 is provided at the end of the first cylinder 3 and the second cylinder 301 away from the inner wall of the working box 1. The second conveying pipe 315 is connected to the two sets of second spray pipes 311 respectively. The first cylinder 3 and the second cylinder 301 are both slidably connected to the first piston 302. The first piston 302 is provided with the connecting rod 303. The end of the connecting rod 303 away from the first piston 302 is fixedly connected to the push plate 304. The two push plates 304 are fixedly connected to the irregular plate 206.

[0041] Both sides of the placement platform 2 are fixedly connected to baffles 204. A guide rod 205 is fixedly connected inside the work box 1. The baffles 204 are slidably connected to the guide rod 205. The two push plates 304 are respectively attached to the outer surface of the two baffles 204 on the side that are close to each other.

[0042] Support plates 305 are fixedly connected to the outer walls of the first cylinder 3 and the second cylinder 301. Fixing plates 306 are fixedly connected to the support plates 305. Fixing plates 306 are provided with a first fixing block 307 and a second fixing block 310. A first spray pipe 308 is set on the first fixing block 307, and a second spray pipe 311 is set on the second fixing block 310. A baffle 316 is provided on the first fixing block 307 and the second fixing block 310. The baffle 316 prevents the material sprayed from the first spray head 309 from being sprayed onto the guide rod 205, thus not affecting the normal movement of the placement platform 2.

[0043] The first conveying pipe 314 is connected to the first fixed block 307, and the second conveying pipe 315 is connected to the second fixed block 310. The first fixed block 307 is provided with a first pipe that communicates with the first conveying pipe 314 and the first spraying pipe 308. The second fixed block 310 is provided with a second pipe that communicates with the second conveying pipe 315 and the second spraying pipe 311. An air inlet pipe 317 is provided at one end of the first cylinder 3 and the second cylinder 301 near the support plate 305.

[0044] In this embodiment, when the placement platform 2 moves, it drives the baffle 204 fixedly connected to it to move, thereby causing the baffle 204 to push 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 inside the first cylinder 3, thereby squeezing the spraying material, causing it to enter the first spraying pipe 308 through the first conveying pipe 314, and then spraying it 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 different The shaped plate 206 drives the push plate 304 on the other side of the placement platform 2 to move, thereby driving the second cylinder 301 to start working. The two push plates 304 are respectively attached to the outer surfaces of the adjacent sides of the two baffles 204. That is, when the placement platform 2 moves to the right, the front baffle 204 will drive the push plate 304 to move. When the placement platform 2 returns to its original position and moves to the left, the rear baffle 204 will drive the push plate 304 to continue to move synchronously. The shaped plate 206 can connect the two push plates 304, thereby realizing reciprocating work and improving work efficiency.

[0045] 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 air inlet pipe 317 can facilitate the intake of air into the first cylinder 3 and the second cylinder 301, thereby realizing the subsequent air drying operation. In addition, the air inlet pipe 317 is also equipped with a one-way valve to prevent gas from leaking from the air inlet pipe 317.

[0046] Example 3: Refer to Figures 2-8 An automotive parts painting device is basically the same as in Embodiment 2, but further, the working box 1 is also provided with two painting boxes 4. The painting box 4 is provided with a partition 401, which divides the painting box 4 into a material extraction area 402 and a stirring area 403. The first cylinder 3 and the second cylinder 301 are both provided with material extraction pipes 313, and the material extraction pipes 313 on the first cylinder 3 and the second cylinder 301 are respectively connected to the material extraction areas 402 of the two painting boxes 4.

[0047] A third cylinder 5 is fixedly installed inside the spray box 4. A second piston 501 is installed inside the third cylinder 5. A thick rod 502 is installed on the outer wall of the second piston 501. A thin rod 504 is slidably connected inside the thick rod 502. A fixed rod 505 is fixedly connected to the end of the thin rod 504 away from the thick rod 502. A circular plate 506 is provided on the fixed rod 505 that abuts against the push plate 304.

[0048] The top outer wall of the third cylinder 5 is provided with an air extraction pipe 6, and the bottom of the third cylinder 5 is provided with a first exhaust pipe 601 and multiple second exhaust pipes 602. Multiple exhaust ports 603 are provided on the first exhaust pipe 601, and one-way valves are provided on the air extraction pipe 6, the first exhaust pipe 601 and the second exhaust pipes 602.

[0049] In this embodiment, when the placement platform 2 moves to the right, it compresses the material inside the first cylinder 3 for spraying, and simultaneously causes the second cylinder 301 to extract the material. Furthermore, the movement of the placement platform 2 moves the baffle 204 and the push plate 304, which in turn moves the circular plate 506 and the fixing rod 505. Then, the thin rod 504 and the thick rod 502 drive the second piston 501 to move, causing the second piston 501 to compress the gas inside the third cylinder 5. This gas is then discharged through the first exhaust pipe 601 and the second exhaust pipe 602 to the bottom of the spray box 4, thus spraying... Bubbles are generated at the bottom of the coating box 4, forming an airflow that agitates the previously relatively still or poorly flowing coating material. This causes the coating particles to collide and mix, which helps to better and more evenly distribute materials of different components and batches, improving the overall mixing effect. Secondly, the air jet can drive the air inside the coating box 4 to circulate, avoiding localized areas of poor air circulation and reducing the accumulation of material in certain areas. This makes the material concentration in different locations within the box more consistent, further improving the mixing uniformity and increasing material utilization.

[0050] Furthermore, the thin rod 504 can slide on the thick rod 502, which increases the buffering effect and prevents the push plate 304 from continuously pressing the thick rod 502 and causing it to jam, making it convenient to use.

[0051] It should also be noted that the spray box 4 is divided into a material extraction zone 402 and a mixing zone 403 by a partition 401. The material extraction zone 402 is relatively calm. When the placement platform 2 needs to be moved to the left to reset, the first cylinder 3 will draw the spraying material into the material extraction zone 402 to prevent air bubbles from entering the first cylinder 3 and affecting the spraying effect. When the spraying material in the material extraction zone 402 decreases, the material mixed in the mixing zone 403 can enter the material extraction zone 402 through the channel between the bottom of the partition 401 and the spray box 4, thus facilitating recycling.

[0052] A first spring 503 is sleeved on the outer wall of the thick rod 502. The first spring 503 is located 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. The second spring 507 is sleeved on the outer wall of the thin rod 504.

[0053] When the placement platform 2 moves to the right, it stretches the first spring 503. When the placement platform 2 returns to the left, the first spring 503 drives the second piston 501 to automatically return to the original position, thereby allowing the third cylinder 5 to draw gas through the suction pipe 6 and let it enter the third cylinder 5. When the placement platform 2 moves to the right again, it can continue to achieve the effect of jet stirring. The suction pipe 6, the first exhaust pipe 601 and the second exhaust pipe 602 are all equipped with one-way valves, which can better realize the jet operation. The outer wall of the third cylinder 5 is also equipped with an air port to facilitate the left side air intake of the second piston 501.

[0054] The outer wall of the work box 1 is provided with a stepper motor 101, the output end of the stepper motor 101 is provided with a threaded rod 102, the placement platform 2 is threadedly connected to the threaded rod 102, the work box 1 is also provided with a limiting rod 103, the placement platform 2 is slidably connected to the limiting rod 103, and the bottom inner surface of the work box 1 is fixedly connected with a vertical plate 104.

[0055] In this invention, starting the stepper motor 101 can drive the threaded rod 102 to rotate, thereby moving the placement platform 2 to achieve subsequent operations. The limiting rod 103 can make the movement of the placement platform 2 more stable. The irregular plate 206 moves at the bottom of the placement platform 2 without interfering with the placement platform 2. The stepper motor 101 can realize forward and reverse operation. When rotating forward, the placement platform 2 moves to the right. When the stepper motor 101 reverses, it can make the placement platform 2 move to the left and reset.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
