Description

Technical Field

[0001] The present invention relates to the technical field of automobile spraying, in particular to an automobile spraying device and method with uniform spraying. Background Art

[0002] As a key product in modern industry, automobiles' exterior coatings not only impact their aesthetics but also play a key role in their corrosion and weather resistance. During the automotive manufacturing process, spray painting is a key component in ensuring surface quality. Traditional spray painting methods typically utilize fixed nozzles combined with manual or mechanical movement of the workpiece. However, this method suffers from uneven coating, low efficiency, and paint waste, making it difficult to meet the high-precision, high-quality spraying requirements of modern automotive manufacturing.

[0003] A search revealed a utility model patent with publication number CN217190392U, which discloses a uniform spraying device for automotive fascia production. This device uses a threaded shaft to drive a spray head in reciprocating motion, achieving linear spraying of the fascia. However, this utility model patent suffers from the following issues: the spray head moves only in a single direction, making it difficult to cover the entire surface of the workpiece, which can easily lead to uneven spraying or missed coatings. In light of this, we propose a uniform automotive spraying device and method. Summary of the Invention

[0025] When in use, the upper side of the base plate 1 can be used to place the reciprocating mechanism 8 and the translation mechanism 9. The support plate 2 is connected to one side of the base plate 1, and the upper side can be used to place the spray liquid tank 3. The placement plate 7 is used to place the car cover to be sprayed, and the left and right movement of the placement plate 7 is controlled by the reciprocating mechanism 8, and the forward and backward movement of the placement plate 7 is controlled by the translation mechanism 9. In this way, the car cover can be evenly sprayed in all aspects through the spraying assembly.

[0026] In this embodiment, the spraying assembly includes a paint pump 4, a first pipe 5, and a second pipe 6. The paint pump 4 is fixedly installed on the top of the spray liquid tank 3. The input end of the paint pump 4 is fixedly connected to the first pipe 5. The bottom of the first pipe 5 passes through the inner cavity of the spray liquid tank 3. The output end of the paint pump 4 is fixedly connected to the second pipe 6. The end of the second pipe 6 is provided with a nozzle 61. The placement plate 7 is provided directly below the nozzle 61. The top of the spray liquid tank 3 is also provided with a liquid inlet 18.

[0027] The spray liquid tank 3 can be filled with paint through the opened liquid inlet 18. The paint pump 4 is located on the upper side of the spray liquid tank 3. The paint pump 4 can extract the paint inside the spray liquid tank 3 through the first pipe 5 and spray it out through the nozzle 61 at the end of the second pipe 6. The placement plate 7 is arranged directly below the nozzle 61, so that the nozzle 61 can spray the paint onto the surface of the car cover, thereby realizing the spraying process.

[0028] In this embodiment, the reciprocating mechanism 8 includes a splint 81, the bottom end of which is slidably set on the top of the base plate 1, the top of the splint 81 is fixedly connected to a first motor 82, the output shaft of the first motor 82 is fixedly connected to a fixed bar 83, the other end of the top of the fixed bar 83 is fixedly connected to an extrusion block 84, the bottom of the placement plate 7 is fixedly connected to a hollow bar 85, the extrusion block 84 is slidably set inside the hollow bar 85, the two ends of the hollow bar 85 are fixedly connected to sliders 86, the front and rear sides of the top of the splint 81 are symmetrically fixedly connected to support rods 87, and the inner cavities of the sliders 86 are slidably sleeved on the support rods 87 respectively.

[0029] It should be noted that the splint 81 can be used to support the first motor 82, and the first motor 82 can drive the fixed bar 83 to rotate, and the extrusion block 84, the fixed bar 83 and the first motor 82 form a Z shape, so that the first motor 82 can drive the extrusion block 84 to perform circular motion through the fixed bar 83, and the extrusion block 84 is slidably arranged inside the hollow bar 85, so that the extrusion block 84 can squeeze the hollow bar 85 to move back and forth when performing circular motion, and the hollow bar 85 can drive the placement plate 7 and the upper side of the car cover to move back and forth in the left and right directions, which enables the cover to be painted in a straight line in the left and right directions when spraying paint, thereby improving the painting range, and the support rod 87 can limit the hollow bar 85 through the slider 86, so that the hollow bar 85 can be stably translated when squeezed and moved by the extrusion block 84 without any offset.

[0030] As a preferred implementation scheme of this embodiment, the translation mechanism 9 includes a second motor 13, a rotating rod 94, a gear 95, and a rack 96. The second motor 13 is fixedly installed on the right side of the base plate 1. The output shaft of the second motor 13 is fixedly connected to the rotating rod 94. The other end of the rotating rod 94 is fixedly connected to the gear 95. The rack 96 is fixedly set at the bottom of the splint 81, and the gear 95 is engaged with the rack 96.

[0031] It should be noted that the second motor 13 controls the rotating rod 94 to rotate at the bottom of the splint 81, and the rotating rod 94 can drive the gear 95 to rotate together. When the gear 95 rotates, it can drive the splint 81 and the cover plate on the upper side of the placement plate 7 to translate in the front and rear directions through the rack 96 engaged with it. Through the cooperation of the translation mechanism 9 and the reciprocating mechanism 8, the spraying assembly can evenly spray the entire surface of the cover plate by gradually moving the cover plate back and forth after spraying a line of paint on the car cover plate left and right, so that the spraying effect of the cover plate is better.

[0032] Furthermore, a first fixed block 91 and a second fixed block 92 are symmetrically arranged on the left and right sides of the top of the base plate 1, and a limiting groove 10 is provided on the top of the first fixed block 91 and the second fixed block 92. The bottom of the splint 81 is fixedly connected to the limiting block 11, and the limiting block 11 is slidably arranged inside the limiting groove 10. A hollow groove 97 is provided in the middle of the second fixed block 92, and the rotating rod 94 is movably arranged inside the hollow groove 97.

[0033] The first fixed block 91 and the second fixed block 92 can be used to support both sides of the bottom of the splint 81, and limit the splint 81 through the limiting groove 10 and the limiting block 11, so that the splint 81 can be stably moved in the front and rear directions on the upper side of the base plate 1. By opening a hollow groove 97 in the middle of the second fixed block 92, the rotating rod 94 can be prevented from affecting the front and rear movement of the splint 81, and will not affect the rotation of the rotating rod 94.

[0034] Furthermore, a hollow block 93 is fixedly connected to the top of the bottom plate 1 , and a rotating rod 94 is rotatably connected to the inner cavity of the hollow block 93 .

[0035] The hollow block 93 can be used to support the rotating rod 94 so that the rotating rod 94 can rotate stably at the bottom of the clamping plate 81.

[0036] In this embodiment, a fixing plate 12 is fixedly connected to the right side of the base plate 1 , and the second motor 13 is fixedly installed on the top of the fixing plate 12 .

[0037] The fixing plate 12 can be used to support the second motor 13, and the second motor 13 can drive the rotating rod 94 to rotate. The self-locking property of the second motor 13 can also make the gear 95 more stable after rotation, thereby making the rack 96 and the splint 81 more stable.

[0038] In this embodiment, the two sides of the hollow bar 85 are fixedly connected with reinforcement rods 14, the top of the reinforcement rods 14 is fixedly connected to the bottom of the placement plate 7, and the top of the placement plate 7 is fixedly connected with an annular baffle 15.

[0039] The reinforcing rod 14 can reinforce the connection between the hollow bar 85 and the placement plate 7, making the placement plate 7 more firmly connected to the top of the hollow bar 85. The annular baffle 15 can be used to limit the position of the car cover placed on the upper side of the placement plate 7, so that the cover is not easily separated from the placement plate 7 when moving on the upper side of the placement plate 7.

[0040] In this embodiment, the end of the second pipe 6 is fixedly connected with a connecting block 17, and the top of the spray liquid tank 3 is fixedly connected with an L-shaped fixing rod 16. The L-shaped fixing rod 16 is symmetrically arranged on both sides of the second pipe 6, and the other end of the L-shaped fixing rod 16 is fixedly connected to the left side of the connecting block 17.

[0041] The L-shaped fixing rod 16 can be used to connect the connecting block 17, and the connecting block 17 can reinforce the second pipe 6, so that the second pipe 6 is more stable on the upper side of the placement plate 7 and is less likely to shake and cause unstable painting.

[0042] A method for using a uniformly spraying automobile spraying device comprises the following steps: S1. Place the car cover to be painted on the placement plate 7, start the paint pump 4 to extract the paint from the spray liquid tank 3 through the first pipe 5, and then spray the paint onto the surface of the car cover on the upper side of the placement plate 7 through the nozzle 61 at the end of the second pipe 6, thereby completing the spraying process on the car cover; S2. The first motor 82 drives the fixing bar 83 to rotate, and the fixing bar 83 drives the extrusion block 84 to perform a circular motion. At the same time, the extrusion block 84 squeezes and drives the hollow bar 85 to move back and forth. At the same time, the hollow bar 85 drives the placement plate 7 and the upper car cover to move back and forth together, so that the spray head 61 can spray paint on the cover in the left and right directions; S3. The second motor 13 is used to control the rotation of the rotating rod 94, which drives the gear 95 to rotate together. The gear 95 drives the rack 96 to move, and the rack 96 drives the clamping plate 81 and the car cover on the upper side of the placement plate 7 to move in the front and rear directions, so that the nozzle 61 can spray the car cover evenly in all aspects.
