Description

[0002] During the production process of automobile lamps, it is usually necessary to spray the surface of the lamp housing. The existing spraying process mostly uses UV paint to spray the surface of the lamp housing. After the UV paint is sprayed onto the lamp housing, it is cured by an ultraviolet lamp. The UV paint is cured to form a protective film on the surface of the lampshade to protect the lamp.

DETAILED DESCRIPTION

[0031] During the production process of automobile lamps, it is necessary to spray UV paint on the lamp housing to protect the lamp. Since UV paint will solidify under the irradiation of ultraviolet rays, after stopping spraying, the paint at the nozzle part will be exposed to ultraviolet rays in natural light, which will easily cause the paint at the nozzle part to solidify and agglomerate. For this reason, the present invention makes the following improvements.

[0033] Reference Figure 5-Figure 7As shown, the closing mechanism includes two symmetrically distributed pull ropes 12, the lower ends of the two symmetrically distributed pull ropes 12 are respectively fixed to the adjacent first light baffle 11 and the adjacent second light baffle 111, and the upper ends of the symmetrically distributed pull ropes 12 are connected to the adjacent first nozzle 10. Initially, the pull ropes 12 are in a relaxed state, the first light baffle 11 is in contact with the adjacent second light baffle 111, the first light baffle 11 is fixed with two symmetrically distributed first elastic ropes 13, the first elastic rope 13 passes through the adjacent second light baffle 111 and is fixed to the sliding shell 101, the first elastic rope 13 is used to reset the adjacent first light baffle 11, the second light baffle 111 is fixed with two symmetrically distributed second elastic ropes 131, the second elastic rope 131 passes through the adjacent first light baffle 11 and is fixed to the sliding shell 101, the second elastic rope 131 is used to reset the adjacent second light baffle 111, and a control component for controlling the sliding of the adjacent sliding shell 101 is arranged in the first nozzle 10.

[0034] Reference Figure 6-Figure 8 As shown, the control component includes a tension spring 14, which is always in a power storage state. The tension spring 14 is fixed between the adjacent first nozzle 10 and the adjacent sliding shell 101. The tension spring 14 is used to reset the adjacent sliding shell 101. The sliding shell 101 is fixed with a limit rod 15, and the limit rod 15 is rotatably connected to a rotating disk 16. The rotating disk 16 is provided with circumferentially distributed fan blades, and the middle part of the rotating disk 16 is hemispherical. When the UV paint passes through the fan blades on the rotating disk 16, the UV paint drives the fan blades on the rotating disk 16 to rotate, stirs the UV paint, and reduces the viscosity of the UV paint. The rotating disk 16 is sealed with the circular tube in the adjacent first nozzle 10. Initially, the rotating disk 16 blocks the circular tube in the middle of the first nozzle 10.

[0035] When the UV coating is sprayed on the shell of the automobile lamp by the device, the shell of the automobile lamp is first placed on the fixing part 4, and then the electric suction cup on the fixing part 4 is started, and the shell of the automobile lamp is fixed on the fixing part 4 by the adsorption of the electric suction cup. After the fixing is completed, the electric turntable 2 is started by the control terminal, and the electric turntable 2 drives the four fixing parts 4 (seen from top to bottom) to rotate clockwise through the four first telescopic rods 3. The fixing part 4 drives the shell (referring to the shell of the automobile lamp) to move to the front half of the workbench 1. The shell is located above the workbench 1. During this process, the shell gradually moves to the bottom of the two first nozzles 10, and then the staff starts the external paint supply system to spray the UV coating through the first nozzle 10. At the same time, the shell of the automobile lamp rotates clockwise around the electric turntable 2 to spray the shell of the automobile lamp.

[0036] In the process of the first nozzle 10 spraying UV paint, taking a first nozzle 10 as an example, initially, the rotating disk 16 seals the circular tube in the middle of the first nozzle 10, and the external UV paint enters the circular tube in the middle of the first nozzle 10 and squeezes the rotating disk 16 downward. The rotating disk 16 drives the limit rod 15 to move downward, and the limit rod 15 drives the sliding shell 101 to move downward. The sliding shell 101 pulls the tension spring 14, and the tension spring 14 is stretched.

[0037] During the downward sliding of the sliding shell 101, the second limiting ring on the sliding shell 101 gradually contacts the first limiting ring on the first nozzle 10, limiting the sliding shell 101 so that the sliding shell 101 no longer moves downward, and the rotating disk 16 is completely separated from the first nozzle 10. Figure 7 As shown, at this time, the UV paint enters the lower side of the sliding shell 101 from the circular tube in the middle of the first nozzle 10 through the rotating disk 16, and then is sprayed out from the lower side of the sliding shell 101.

[0038] Initially, the first light baffle 11 and the second light baffle 111 are in contact with each other. During the downward sliding of the sliding shell 101, the nozzle on the lower side of the sliding shell 101 is blocked by the first light baffle 11 and the second light baffle 111 to prevent the UV paint at the nozzle position of the sliding shell 101 from being solidified by light and affecting the quality of the sprayed UV paint. When the sliding shell 101 moves downward, the sliding shell 101 drives the first light baffle 11, the second light baffle 111, the first elastic rope 13 and the second elastic rope 131 to move downward synchronously. During the downward movement of the first light baffle 11 and the second light baffle 111, they are respectively pulled by the adjacent pull ropes 12. The first light baffle 11 and the second light baffle 111 are separated by the pull ropes 12, and the nozzle on the sliding shell 101 is opened to allow the UV paint to be sprayed normally. During the separation of the first light baffle 11 and the second light baffle 111, the two first elastic ropes 13 and the two second elastic ropes 131 are stretched and charged.

[0039] In the process of the first nozzle 10 spraying the UV paint, the UV paint passes through the circumferentially distributed blades on the upper side of the rotating disk 16. When the UV paint passes through the blades on the rotating disk 16, it will drive the rotating disk 16 to rotate. The rotating disk 16 rotates on the limiting rod 15. During the rotation, the rotating disk 16 stirs the passing UV paint to improve the mixing degree of the UV paint and reduce the viscosity of the UV paint (the UV paint is thixotropic, with high viscosity when standing still, and the viscosity decreases when pumped and stirred), so that the UV paint is sprayed evenly.

[0040] When the automobile lamp housing passes through the first spray head 10, the external paint supply system is turned off, the first spray head 10 stops spraying paint, and then the tension spring 14 drives the sliding shell 101 to reset, and the sliding shell 101 drives the rotating disk 16 to reset through the limit rod 15. During the resetting process of the sliding shell 101, the two pull ropes 12 release the first light baffle 11 and the second light baffle 111, and the first light baffle 11 and the second light baffle 111 are combined under the pull of the first elastic rope 13 and the second elastic rope 131, and the nozzle of the sliding shell 101 is blocked, and then the above process is repeated to spray the shells on the four fixing parts 4 in turn.

[0041] After the automobile lamp housings on the four fixing members 4 are sprayed, the driving suction cups on the fixing members 4 are closed, the four automobile lamp housings are disassembled, and then the electric turntable 2 is controlled by the control terminal to rotate in the opposite direction for one circle to reset, and the spraying is completed.

[0042] During the spraying process, due to the irregular shape of the automobile lamps, it is easy to cause uneven spraying and leakage during spraying. For this reason, the following improvements are made.

[0043] Example 2: Based on Example 1, refer to Figure 3 , Fig. 9 and Fig.10 As shown, it also includes a fixed plate 21, which is fixed to the mounting frame 5. The front and rear sides of the fixed plate 21 are rotatably connected to the first rotating shaft 22. A first torsion spring 23 is fixed between the first rotating shaft 22 and the mounting frame 5. Initially, the first torsion spring 23 stores force, and the first rotating shaft 22 is fixed to two second telescopic rods 24 symmetrically distributed up and down. The telescopic ends of the two second telescopic rods 24 symmetrically distributed up and down are rotatably connected to the second rotating shaft 25. The second rotating shaft 25 is used to detect the front and rear widths of the shell. The fixed frame 6 is fixed to two symmetrically distributed first limit blocks 26, which are limited by the adjacent sliding block 7. The first limit block 26 is used to limit the moving range of the sliding block 7. An adjusting component for controlling the up and down movement of the first nozzle 10 is provided on the outer side of the fixed plate 21.

[0044] Reference Figure 3 and Figure 9-11As shown, the adjustment assembly includes two symmetrically distributed rotating frames 27, which are both rotatably connected to the fixed plate 21, and the limit shaft 8 is slidably connected to the adjacent fixed block 9. A second torsion spring 271 is arranged between the two symmetrically distributed rotating frames 27 and the fixed plate 21, and the second torsion spring 271 is used to drive the adjacent rotating frames 27 to swing upward. The rotating frames 27 are slidably connected to the slider 28, and the slider 28 is slidably connected to the sliding member 29. The sliding member 29 consists of a long round rod, a ring and a short round rod. The ring on the sliding member 29 is connected to the adjacent second rotating frame 27. The moving shaft 25 is slidably connected, and the short round rod on the sliding member 29 is rotatably connected with a sleeve 30. The sleeve 30 contacts the lower side of the shell when in use and is used to detect the position of the edge of the shell. The sliding member 29 is fixedly connected to a limiting sleeve 31, and the limiting sleeve 31 is slidably connected to the adjacent limiting shaft 8. The limiting sleeve 31 is fixedly connected to the adjacent fixed block 9. The fixed frame 6 is fixedly connected to two electric telescopic rods 32 symmetrically distributed front and back. The telescopic end of the electric telescopic rod 32 is squeezed and matched with the adjacent rotating frame 27. Initially, the telescopic end of the electric telescopic rod 32 extends out to squeeze the adjacent rotating frame 27, so that the rotating frame 27 is as shown in FIG. Figure 3 Status shown.

[0045] Reference Fig.11 and Fig.12 As shown, the two symmetrically distributed fixed blocks 9 are both spherically connected with a sliding plate 33, the sliding plate 33 is located between the symmetrically distributed fixed blocks 9, the two sliding plates 33 are centrally symmetrically distributed, a rack is provided between the two sliding plates 33, the middle parts of the centrally symmetrically distributed sliding plates 33 are slidably connected with a second limit block 34, the second limit block 34 is located in the middle part of the two sliding plates 33 forming a whole, the second limit block 34 is rotatably connected with a third rotating shaft 37, the third rotating shaft 37 is provided with a gear, and the third rotating shaft 37 is provided with a gear. The gears are meshed with the racks on the two sliding plates 33. The second limit block 34 is fixedly connected to an electric shaft 35, which is electrically connected to the control terminal. The output shaft of the electric shaft 35 is fixedly connected to a second nozzle 36, which is used to spray paint on the middle part of the shell. The second nozzle 36 is connected to an external paint supply system. The second nozzle 36 has the same structure as the first nozzle 10. Position sensors electrically connected to the control terminal are provided in the symmetrically distributed sliding blocks 7 for detecting the position of the sliding blocks 7 on the fixed frame 6.

[0046] In the process of the fixing member 4 driving the shell to rotate clockwise, taking the shell on the front fixing member 4 as an example, the left side of the shell first passes through the two second rotating shafts 25. Since the front-to-back width of the shell from the left side to the right side first increases and then decreases, the control terminal controls the external paint supply system at this time to make the second nozzle 36 spray UV paint outward, and the narrow part of the left side of the shell is sprayed through the second nozzle 36. Then the shell continues to move. When the shell starts to squeeze the two second rotating shafts 25, the second rotating shaft 25 drives the adjacent sliding block 7 to move, and the position sensor in the sliding block 7 transmits an electrical signal to the control terminal, and the control terminal controls the telescopic end of the electric telescopic rod 32 to retract upward (initially, the telescopic end of the electric telescopic rod 32 squeezes the rotating frame 27, so that the rotating frame 27 remains as shown in FIG. Fig. 9 In the position shown, the second torsion spring 271 stores force), releases the rotating frame 27, and the rotating frame 27 rotates upward under the action of the second torsion spring 271. The rotating frame 27 drives the sliding member 29 to move through the adjacent slider 28, and the sliding member 29 drives the adjacent sleeve 30 and the adjacent limiting sleeve 31 to move upward. During the upward movement of the sleeve 30, it gradually contacts the lower edge of the shell and stops under the limit of the shell. During the upward movement of the limiting sleeve 31, it drives the adjacent fixed block 9 to move upward, and the fixed block 9 drives the adjacent first nozzle 10 to move upward, so that the first nozzle 10 always maintains a certain distance from the upper side of the shell, thereby improving the uniformity and stability of the first nozzle 10 spraying on the shell.

[0047] During the movement of the shell in the above process, the width of the part of the shell located between the two second rotating shafts 25 in the front-to-back direction gradually increases, the shell squeezes the two second rotating shafts 25, the two second rotating shafts 25 drive the two adjacent second telescopic rods 24 to rotate, the telescopic parts of the second telescopic rods 24 slide when the adjacent second rotating shafts 25 move, the two second telescopic rods 24 jointly drive the adjacent first rotating shafts 22 to rotate, the adjacent first torsion springs 23 store force (initially, the first torsion springs 23 are also in the stored force state), the shell is squeezed by the two second rotating shafts 25 and is located in the middle of the fixed frame 6, in this process, the shell causes the telescopic ends of the adjacent first telescopic rods 3 to slide through the adjacent fixing members 4, so that the shell can be located in the middle of the fixed frame 6. During the movement of the second rotating shaft 25, the sliding block 7 moves synchronously. When the sliding block 7 moves to a certain distance (at this time, the second nozzle 36 cannot completely spray the upper surface of the shell), the control terminal controls the two first nozzles 10 to spray paint outward to supplement the edges that the second nozzle 36 cannot spray. When the sliding block 7 moves to a position where the first nozzle 10 and the second nozzle 36 are still unable to spray in a fixed state (the positions of the two sliding blocks 7 reflect the front and rear width of the shell), the control terminal starts the electric rotating shaft 35 according to the distance moved by the sliding block 7, and controls the reciprocating angle of the output shaft of the electric rotating shaft 35. The second nozzle 36 is controlled to swing back and forth through the electric rotating shaft 35 to spray the upper surface of the shell.

[0048] During the spraying process, the front and rear two first nozzles 10 are both located at the edge of the shell and are at the same distance from the upper edge of the shell. Due to the irregular shape of the shell, during the spraying process, the first nozzle 10 and the adjacent fixed block 9 move up and down along the adjacent limit shaft 8. During the movement, the two sliding plates 33 swing at the same time, and when the two second rotating shafts 25 drive the two fixed blocks 9 away from each other, the two sliding plates 33 move relative to each other, and drive the third rotating shaft 37 to rotate on the second limit block 34 through the gear and rack, so that the third rotating shaft 37 is always located in the middle of the two sliding plates 33 to form a whole, thereby making the second nozzle 36 located in the middle of the two first nozzles 10, and the second nozzle 36 is tilted and facing the shell, so that the second nozzle 36 is sprayed more evenly to the top of the shell when swinging, reducing the influence of the shell shape on the spraying.

[0049] After spraying is completed, the started electrical components are turned off, and then the electric telescopic rod 32 is started. The telescopic end of the electric telescopic rod 32 moves downward and squeezes the adjacent rotating frame 27 to reset the rotating frame 27. The first torsion spring 23 drives the two adjacent second telescopic rods 24 to reset through the adjacent first rotating shaft 22, thereby resetting the second rotating shaft 25, so that the device is reset to the initial state for the next use.

[0050] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
