Description

Technical Field

[0001] This invention relates to the field of automotive rearview mirror manufacturing technology, and more particularly to an automotive rearview mirror painting system. Background Technology

[0002] The rearview mirror housing is part of the car's exterior components. Painting the rearview mirror housing is often a crucial step in enhancing the car's aesthetics. In recent years, with the advancement of painting technology, the traditionally human-driven painting process has transformed into automated processing led by robotic arms. However, in practice, to achieve comprehensive painting of the rearview mirror housing, a top-pumping component typically extends inwards into the housing to provide support. However, this type of component cannot effectively secure the rearview mirror, and the supporting force is insufficient to withstand the spraying force applied during painting. In other words, during the painting process, the rearview mirror is prone to frequent positional shifts due to the spraying force, hindering even painting. Summary of the Invention

[0003] The purpose of this invention is to provide a car rearview mirror painting system that secures the car rearview mirror during the painting process, preventing it from shifting due to the spraying force.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A car rearview mirror painting system, comprising:

[0006] The upper disc is placed horizontally;

[0007] At least one spreading member is disposed on the upper side of the upper disk;

[0008] When the car rearview mirror is flipped upside down onto the support component, the support component expands outward and contacts the inside of the car rearview mirror housing, thereby making the car rearview mirror stably arranged on the upper side of the upper disc.

[0009] Preferably, the spreading component includes a fixing block fixed to the upper side of the upper disc. One side of the fixing block has a fixed circular rubber block, and the opposite side has an adjustable circular rubber block. The adjustable circular rubber block moves away from the fixed circular rubber block and comes into contact with the inside of the car rearview mirror housing. Under the contact with the inner wall of the housing, the circular rubber block bends and deforms accordingly.

[0010] Preferably, a first connecting rod is fixedly connected to one side of the fixing block, and the first connecting rod is perpendicularly fixedly connected to one of the circular rubber blocks. A second connecting rod is slidably connected to the opposite side of the fixing block, and the second connecting rod is perpendicularly fixedly connected to the other circular rubber block. A rectangular groove is formed inside the fixing block, and a first hydraulic cylinder is fixedly installed in the rectangular groove. The output shaft of the first hydraulic cylinder is fixedly connected to a circular block. A first rod body is coaxially fixedly connected to the circular block. A first circular groove is formed on the first rod body. A sliding groove is formed on the fixing block. The second connecting rod is slidably connected to the inner wall of the sliding groove. A second circular groove is formed on the second connecting rod. The diameter of the circular block is the same as the diameter of the second circular groove. A second rod body is fixedly connected in the second circular groove. The second rod body is adapted to the first circular groove and slidably connected to it. A first spring is sleeved on the outer wall of the first rod body, and the two ends of the first spring are respectively connected to the circular block and the second connecting rod.

[0011] Preferably, a rotating component is added between the second connecting rod and the circular rubber block. The rotating component includes a rectangular block fixedly connected to the second connecting rod, the rectangular block having a through hole. The circular rubber block connected to the second connecting rod has three parts: a non-deformable second rotating shaft and deformable parts fixed at both ends of the second rotating shaft. The deformable parts are made of elastic rubber. The second rotating shaft passes through the through hole, and a toothed groove is formed on the outer wall of the second rotating shaft. A second hydraulic cylinder is mounted on the rectangular block, and a rack is fixedly connected to the output end of the second hydraulic cylinder. The rack is adapted to the toothed groove, thereby enabling the second rotating shaft to mesh with the rack.

[0012] Preferably, the upper disk has an annular structure, and a third rotating shaft is set at the center of the inner ring of the upper disk. The third rotating shaft is fixedly connected to the inner ring of the upper disk through multiple connecting blocks. The bottom end of the third rotating shaft is fixedly connected to the lower disk, and a driven gear is fixedly sleeved on the outer wall of the third rotating shaft. A servo motor is installed on the lower disk, and the output shaft of the servo motor is fixedly sleeved on the driving gear. The driving gear and the driven gear are meshed and connected to each other.

[0013] Preferably, a connecting ring is provided between the upper disk and the lower disk, the connecting ring is fixedly connected to the lower disk, and an internal gear is fixedly connected to the inner ring of the connecting ring. A fixing ring is also provided between the upper disk and the lower disk, the fixing ring is fixedly connected to the third rotating shaft through the connecting block, and at least one fourth rotating shaft is fixedly connected to the fixing ring. Multiple fan blades are fixedly connected to the outer wall of the fourth rotating shaft, and an external gear is fixedly connected to the outer wall of the fourth rotating shaft. The external gear and the internal gear are meshed with each other.

[0014] Preferably, an outlet is provided on the upper disk between the fourth rotating shaft and the fixed block, and an outlet is provided on the side wall of the fixed block to guide the airflow in the rectangular groove to be discharged from each of the outlets.

[0015] A painting method for an automotive rearview mirror painting system, characterized by comprising the following steps:

[0016] The rearview mirror housing is inverted and placed on the upper side of the upper disc;

[0017] The first hydraulic cylinder is activated, driving the two circular rubber blocks to move away from each other until they come into contact with the inner wall of the car rearview mirror housing. During the contact process, the circular rubber blocks are bent and deformed by force, and the specific structure of the deformation is adapted to the inner wall of the housing they are in contact with.

[0018] The second hydraulic cylinder is activated, giving the third rotating shaft a starting force to rotate. This force is applied to the deformable part of the circular rubber block through the rack and the third rotating shaft. Under the action of the sliding friction between the deformable part and the inner wall of the housing, a downward pressure is applied to the housing.

[0019] The servo motor is started, which drives the fixed ring to rotate, which in turn drives the external gear to revolve. Under the action of the fixed internal gear, the external gear drives the fourth shaft to rotate, causing the fan blades to rotate and blow out airflow. The airflow flows out through the inlet and multiple outlets, and finally flows out from the gap between the car rearview mirror and the upper disc.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention employs a fixed circular rubber block and an adjustable circular rubber block. The car rearview mirror is inverted and placed around the two circular rubber blocks. The position of the adjustable circular rubber block is adjusted so that the two circular rubber blocks move away from each other until they contact the inner wall of the car rearview mirror housing. During the contact process, the circular rubber blocks bend and deform accordingly. The circular rubber blocks contact the inner wall of the housing, thereby stabilizing the position of the car rearview mirror on the upper disc. At the same time, the sliding friction between the circular rubber blocks and the inner wall of the housing is used to prevent the car rearview mirror from shifting arbitrarily.

[0022] 2. In this invention, the rotation of the second rotating shaft drives the circular rubber block to rotate. When rotating, it generates sliding friction with the car rearview mirror. This sliding friction is applied to the car rearview mirror, giving it a downward pressure force, thus making the car rearview mirror more stably placed on the upper disc.

Detailed Implementation

[0031] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Reference Appendix Figure 1 - Appendix Figure 7A car rearview mirror painting system includes an upper disc 1 placed horizontally. The upper disc 1 is provided with at least one spreading component. When the car rearview mirror is upside down on the spreading component, the spreading component expands outward and contacts the inside of the car rearview mirror housing, thereby making the car rearview mirror stably arranged on the upper side of the upper disc 1.

[0033] The supporting component includes a fixing block 2 fixed on the upper side of the upper disc 1. One side of the fixing block 2 has a fixed circular rubber block 3, and the opposite side has an adjustable circular rubber block 3. When the car rearview mirror is upside down on the fixing block 2, the adjustable circular rubber block 3 moves away from the fixed circular rubber block 3 and comes into contact with the inside of the car rearview mirror housing. Under the contact with the inner wall of the housing, the circular rubber block 3 bends and deforms accordingly. The circular rubber block 3 and the inner wall of the housing come into contact with each other, thereby stabilizing the position of the car rearview mirror on the upper disc 1. At the same time, the sliding friction between the circular rubber block 3 and the inner wall of the housing is used to prevent the car rearview mirror from shifting randomly.

[0034] A first connecting rod 4 is fixedly connected to one side of the fixed block 2. The first connecting rod 4 is perpendicularly fixedly connected to one of the circular rubber blocks 3. A second connecting rod 5 is slidably connected to the opposite side of the fixed block 2. The second connecting rod 5 is perpendicularly fixedly connected to another circular rubber block 3. A rectangular groove 6 is opened inside the fixed block 2. A first hydraulic cylinder 7 is fixedly installed in the rectangular groove 6. The output shaft of the first hydraulic cylinder 7 is fixedly connected to a circular block 8. A first rod body 9 is fixedly connected to the circular block 8 on the same axis. A first circular groove 10 is opened on the first rod body 9 on the same axis. A sliding groove 11 is opened in the fixed block 2. The second connecting rod 5 is slidably connected to the inner wall of the sliding groove 11. A second circular groove 12 is opened on the second connecting rod 5 on the same axis. The diameter of the circular block 8 is the same as the diameter of the second circular groove 12. A second rod body 13 is fixedly connected inside the second circular groove 12. The second rod body 13 is adapted to the first circular groove 10 and slidably connected to each other. A first spring 14 is sleeved on the outer wall of the first rod body 9. The two ends of the first spring 14 are respectively connected to the circular block 8 and the second connecting rod 5.

[0035] Start the first hydraulic cylinder 7 to drive the circular block 8 to move, so that the second connecting rod 5 and the first connecting rod 4 move away from each other. When the two circular rubber blocks 3 touch the inner wall of the car rearview mirror housing, they bend and deform. After the deformation is completed, the first spring 14 is compressed accordingly, so that the two circular rubber blocks 3 press tightly against the inner wall of the car rearview mirror housing, ensuring that the car rearview mirror is stably placed on the upper disc 1.

[0036] A rotating component is added between the second connecting rod 5 and the circular rubber block 3. The rotating component includes a rectangular block 16 fixedly connected to the second connecting rod 5. The rectangular block 16 has a through hole 17. The circular rubber block 3 connected to the second connecting rod 5 has three parts: a non-deformable second rotating shaft 18 and deformable portions 19 fixed to both ends of the second rotating shaft 18. The deformable portions 19 are made of elastic rubber. The second rotating shaft 18 passes through the through hole 17, and its outer wall has toothed grooves 20. A second hydraulic cylinder 21 is mounted on the rectangular block 16. The output end of cylinder 21 is fixedly connected to rack 22. Rack 22 is adapted to tooth groove 20, so that the second rotating shaft 18 is meshed with rack 22. When the circular rubber block 3 touches and deforms with the inner wall of the car rearview mirror housing, the second hydraulic cylinder 21 is activated, which drives the second rotating shaft 18 to rotate and drives the circular rubber block 3 to rotate. When rotating, it generates sliding friction with the car rearview mirror. This sliding friction is applied to the car rearview mirror so that it has a downward pressing force and is more stably placed on the upper disc 1. Of course, a rotating component can also be added between the first connecting rod 4 and the circular rubber block 3.

[0037] The upper disk 1 has a ring structure. A third rotating shaft 23 is set at the center of the inner ring of the upper disk 1. The third rotating shaft 23 is fixedly connected to the inner ring of the upper disk 1 through multiple connecting blocks 24. The bottom end of the third rotating shaft 23 is fixedly connected to the lower disk 25. The driven gear 26 is fixedly sleeved on the outer wall of the third rotating shaft 23. A servo motor 27 is installed on the lower disk 25. The output shaft of the servo motor 27 is fixedly sleeved on the driving gear 28. The driving gear 28 and the driven gear 26 are meshed and connected to each other. Starting the servo motor 27 can make the upper disk 1 rotate.

[0038] A connecting ring 29 is provided between the upper disk 1 and the lower disk 25. The connecting ring 29 is fixedly connected to the lower disk 25. An internal gear 30 is fixedly connected to the inner ring of the connecting ring 29. A fixing ring 31 is also provided between the upper disk 1 and the lower disk 25. The fixing ring 31 is fixedly connected to the third rotating shaft 23 through the connecting block 24. At least one fourth rotating shaft 32 is fixedly connected to the fixing ring 31. Multiple fan blades 33 are fixedly connected to the outer wall of the fourth rotating shaft 32. An external gear 36 is fixedly connected to the outer wall of the fourth rotating shaft 32. The external gear 36 and the internal gear 30 are meshed with each other. As the third rotating shaft 23 rotates, it drives the external gear 36 of the fourth rotating shaft 32 to revolve. Because the external gear 36 and the internal gear 30 mesh with each other, the fourth rotating shaft 32 rotates accordingly, and the fan blades 33 rotate to blow out airflow.

[0039] An outlet 34 is opened on the upper disc 1 between the fourth rotating shaft 32 and the fixed block 2, so that the airflow blown out by the rotating fan blade 33 enters the rectangular groove 6 through the outlet 34. An outlet 35 is opened on the side wall of the fixed block 2, so that the airflow in the rectangular groove 6 is guided to be discharged from each outlet 35, and finally flows out from the gap between the car rearview mirror housing and the upper disc 1, thereby blowing away the paint scattered in the air and preventing the paint from entering the interior of the car rearview mirror housing.

[0040] Working principle:

[0041] The car rearview mirror housing is inverted and placed on the upper side of the upper disc 1;

[0042] Start the first hydraulic cylinder 7 to drive the two circular rubber blocks 3 away from each other until they come into contact with the inner wall of the car rearview mirror housing. During the contact process, the circular rubber blocks 3 are bent and deformed by force, and the specific structure of the deformation is adapted to the inner wall of the housing they are in contact with.

[0043] The second hydraulic cylinder 21 is activated, giving the third rotating shaft 23 a rotational starting force. This force is applied to the deformable part 19 of the circular rubber block 3 through the rack 22 and the third rotating shaft 23. Under the action of the sliding friction between the deformable part 19 and the inner wall of the housing, a downward pressure is applied to the housing, further ensuring the stability between the car rearview mirror and the upper disc 1.

[0044] Start the servo motor 27, which drives the fixed ring 31 to rotate, which in turn drives the external gear 36 to revolve. Under the action of the fixed internal gear 30, the external gear 36 drives the fourth rotating shaft 32 to rotate, which causes the fan blade 33 to rotate and blow out airflow. The airflow flows out through the outlet 34 and multiple outlets 35, and finally flows out from the gap between the car rearview mirror and the upper disc 1.

[0045] 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.
