Description

Technical Field

[0001] This invention relates to the field of plasma cleaning technology, and in particular to a plasma cleaning device for automotive body-in-white. Background Technology

[0002] With the development of industry, the use of robotic arms has enabled manual production lines to gradually evolve into intelligent production lines. By using robotic arms in conjunction with fixtures, manual operations can be replaced, which reduces the labor input in manual production and ensures the consistency of the product production process, thereby improving product quality. This is especially true for automobile production, where it increases production efficiency.

[0003] Currently, in the process of processing the car body-in-white, it is necessary to clean the body using a plasma spray gun. Existing equipment uses a robotic arm in conjunction with the plasma spray gun to clean the body-in-white under program control. However, after working for a long time, the internal electronic components of the plasma spray gun heat up, which makes it prone to failure. The plasma spray gun needs to be replaced manually, causing the robotic arm to be down for a long time and affecting production efficiency.

[0004] Based on this, the present invention designs a plasma cleaning device for automotive body-in-white to solve the above problems. Summary of the Invention

The other end of the connecting spring is connected to the rotating mechanism. The sliding column passes through the rotating mechanism and is slidably connected to the rotating mechanism. The magnetism carried by the magnet after being energized is different from that carried by the permanent magnet.

[0013] Furthermore, the closing mechanism includes a rotating gear ring mounted on a fixed cylinder. The surface of the rotating gear ring is connected to a linkage turntable via two connecting columns. The linkage turntable is rotatably connected to a fixed circular plate, and both rotating columns engage with arc-shaped grooves on the fixed circular plate. The radii of the arc-shaped grooves are equal. The fixed circular plate has straight grooves that engage with two sliding semicircular sleeves. The surface of the linkage turntable has proximal grooves that engage with the two sliding semicircular sleeves. The radii of the proximal grooves gradually approach the central axis of the linkage turntable. Both sliding semicircular sleeves are slidably connected to the surface of the fixed circular plate. The two sliding semicircular sleeves can form a complete open cylinder, and the diameter of the open cylinder is equal to the diameter of the connector. The fixed circular plate is fixedly mounted on the rotating mechanism and slidably connected to the fixed cylinder. An inner arc rack and an outer arc rack that engage with the rotating gear ring are fixedly mounted on the mounting platform. A rotation damper is provided on the linkage turntable.

[0014] Furthermore, the rotating mechanism includes a rotating gear rotatably connected to the driving mechanism. The output end of the rotating gear is connected to the input end of the bevel gear set. The output end of the bevel gear set is coaxially fixedly mounted on the linkage shaft. A connecting block is fixedly mounted on the surface of the linkage shaft. A sliding column passes through the connecting block and is slidably connected to the connecting block. The other end of the connecting spring is connected to the connecting block. A fixed circular plate is fixedly mounted on the connecting block.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention protects the surface of the connector by using a sealing mechanism, preventing external dust from falling onto the surface of the connector during plasma tube switching. This would prevent the connector from affecting conductivity when it is reconnected to the power supply conduit later, thus achieving the purpose of automatically protecting the connector from dust contamination.

[0020] 2. This invention re-energizes the internal electromagnetic mechanism, causing the plasma tube to move vertically upwards and connect the connector to the power supply conduit. The external power supply equipment is then energized again, and the mounting arm returns to the main program to continue the plasma cleaning operation on the vehicle body. This achieves automatic switching of the plasma tube and avoids excessive heat during prolonged operation, which could affect the service life of the plasma tube. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0034] like Figure 1 , Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, in one embodiment, a plasma cleaning device for automotive body-in-white is provided, the device comprising:

[0035] Mechanical body 1: includes a mounting arm 101 provided on the mechanical body 1, a pipe fixing block 102 fixedly mounted on the surface of the mounting arm 101, a mounting frustum 103 fixedly mounted on the surface of the pipe fixing block 102, and an electrical conduit 104 for supplying power to two plasma tubes 201 fixedly mounted on the pipe fixing block 102. One end of the electrical conduit 104 is connected to an external power supply device, and a timer is provided on the external power supply device. The electrical conduit 104 is fixedly connected to the inner wall of the mounting frustum 103.

[0036] Fixing mechanism 2: includes a fixing cylinder 202 installed on the mounting truncated cone 103 and used to fix the plasma tube 201 by cooperating with the fixing bolt 203. The surface of the plasma tube 201 is fixedly installed with a connector 204 that contacts and energizes the other end of the power supply conduit 104.

[0037] Electromagnetic mechanism 3: used to drive the plasma tube 201 to move vertically;

[0038] Enclosure mechanism 4: In cooperation with drive mechanism 6, it isolates the external environment from the power terminal of power connector 204;

[0039] Rotation mechanism 5: It drives the plasma tube 201 to rotate by cooperating with the drive mechanism 6.

[0040] In practical applications, the embodiments of the present invention, such as Figure 1 and Figure 5 As shown, when performing plasma cleaning on the body-in-white, the mounting arm 101, under the action of the program, drives the plasma tube 201 to move and clean the corresponding position on the body-in-white. Simultaneously, a timer on the external power supply device starts counting. When the corresponding running time is reached, the external power supply device is de-energized, and the mounting arm 101 returns to its original position after running the power-off program to avoid interference with the body-in-white during the switching of the plasma tube 201. At this time, the de-energization of the external power supply device causes the electromagnetic mechanism 3 to be de-energized. The de-energization of the electromagnetic mechanism 3 causes the fixed cylinder 202 to move vertically downwards under the elastic potential energy of the electromagnetic mechanism 3, thereby driving the contact head 204 to move vertically downwards and disengage from the power supply conduit 104. Simultaneously, the contact head 204 moves from inside the mounting platform 103 to the outside. After the contact head 204 completes its movement, the plasma tube 201 rotates under the action of the drive mechanism 6. During the revolution of the plasma tube 201, as... Figure 7 , Figure 8 and Figure 9As shown, the sealing mechanism 4 protects the surface of the connector 204, preventing external dust from falling onto the surface of the connector 204 during plasma tube 201 switching. This would affect the conductivity when the connector 204 reconnects with the power supply conduit 104, thus automatically protecting the connector 204 from dust contamination. Simultaneously, under the action of the drive mechanism 6, the sealing mechanism 4 at the symmetrical end moves in the opposite direction when approaching the power supply conduit 104, thus removing the sealing mechanism 4 from the connector 204 and ensuring normal connection between the connector 204 and the power supply conduit 104. Simultaneously, as the drive mechanism 6 synchronously drives the symmetrical end plasma tube 201 to revolve, the rotation mechanism 5 drives the plasma tube 201 to rotate away from the central axis of the mounting frustum 103. At this point, the symmetrical end plasma tube 201 rotates to a vertical position. In the initial state, under the action of the drive mechanism 6, the rotation mechanism 5 causes the plasma tube 201 at the initial end to rotate from a vertical state to a horizontal state. This avoids spatial interference between the plasma tube 201 at the non-working end and the white body during plasma cleaning, thereby expanding the range of motion of the plasma tube 201 at the working end and improving the flexibility of its movement. When the plasma tube 201 at the symmetrical end revolves to the working end, the electromagnetic mechanism 3 is energized again, causing the plasma tube 201 to move vertically upward and drive the connector 204 to connect with the power supply conduit 104. The external power supply equipment is energized again, and the mounting arm 101 returns to the main program to continue the plasma cleaning operation on the car body. This achieves automatic switching of the plasma tube 201 and avoids excessive heat during long-term operation, which could affect the service life of the plasma tube 201.

[0041] like Figure 5 As shown, in a preferred embodiment of the present invention, the electromagnetic mechanism 3 includes a magnet 301 fixedly mounted on the mounting frustum 103, and a permanent magnet 304 fixedly mounted on the fixed cylinder 202. A sliding column 302 is fixedly mounted on the surface of the fixed cylinder 202, and a connecting spring 303 is fixedly mounted on the surface of the sliding column 302. The other end of the connecting spring 303 is connected to the rotating mechanism 5. The sliding column 302 passes through the rotating mechanism 5 and is slidably connected to the rotating mechanism 5. The magnetism of the magnet 301 after being energized is different from that of the permanent magnet 304.

[0042] In practical applications, when the external power supply is interrupted, such as... Figure 5As shown, when the electromagnet 301 is de-energized, it loses its magnetism. Under the action of the connecting spring 303, it drives the sliding column 302 to move vertically downward. This, in turn, drives the contact head 204 to move vertically downward through the fixed cylinder 202, disengaging it from the power supply conduit 104. Simultaneously, the contact head 204 moves to the outside of the mounting frustum 103, facilitating the protection of the energized end of the contact head 204 later. When the plasma tube 201 at the symmetrical end moves to the working end, the electromagnet 301 is re-energized, attracting the permanent magnet 304 to move vertically upward. This, in turn, drives the fixed cylinder 202 to move vertically upward through the connecting spring 303. The fixed cylinder 202 then drives the contact head 204 to move upward and make close contact with the power supply conduit 104, thereby achieving the purpose of automatic switching.

[0043] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in another preferred embodiment of the present invention, the closing mechanism 4 includes a rotating gear ring 401 mounted on a fixed cylinder 202. The surface of the rotating gear ring 401 is connected to a linkage turntable 402 via two connecting posts. The linkage turntable 402 is rotatably connected to a fixed circular plate 404, and both rotating posts mate with arc-shaped grooves on the fixed circular plate 404. The radii of the arc-shaped grooves are equal. The fixed circular plate 404 has straight grooves that mate with two sliding semicircular sleeves 403. The surface of the linkage turntable 402 has proximal grooves that mate with the two sliding semicircular sleeves 403. The radius of the near-center groove gradually approaches the central axis of the linkage turntable 402. Both sliding semicircular sleeves 403 are slidably connected to the surface of the fixed circular plate 404. The two sliding semicircular sleeves 403 can cooperate to form a complete open cylinder, and the diameter of the open cylinder is equal to the diameter of the electrical connector 204. The fixed circular plate 404 is fixedly installed on the rotating mechanism 5, and the fixed circular plate 404 is slidably connected to the fixed cylinder 202. The mounting platform 103 is fixedly installed with an inner arc rack 405 and an outer arc rack 406 that cooperate with the rotating gear ring 401. The linkage turntable 402 is provided with a rotation damper.

[0044] In practical applications of this invention, after the electromagnetic mechanism 3 completes its movement, the plasma tube 201 is driven to revolve under the action of the driving mechanism 6, such as... Figure 7 and Figure 9As shown, during the revolution, the rotating gear ring 401 meshes with the inner arc rack 405, causing the rotating gear ring 401 to rotate. The rotation of the rotating gear ring 401 drives the linkage turntable 402 to rotate synchronously. The linkage turntable 402, through the near-center groove on its surface and the straight groove on the fixed circular plate 404, causes the two sliding semi-circular sleeves 403 to move closer to the central axis of the rotating gear ring 401, thereby forming a complete open cylinder. This isolates and protects the energized end of the connector 204, preventing external dust from falling on the connector 204 and affecting its conductivity. Figure 8 and Figure 10 As shown, the rotating gear ring 401 at the symmetrical end meshes with the outer arc rack 406 during its revolution, causing the rotating gear ring 401 at the symmetrical end to rotate in the opposite direction, thereby opening the sliding semicircular sleeve 403 at the symmetrical end. This allows the electrical connector 204 at the symmetrical end to connect with the power supply conduit 104 under the action of the electromagnetic mechanism 3, achieving the purpose of automatically opening the open cylinder during switching.

[0045] like Figure 6 , Figure 7 and Figure 8 As shown, in another preferred embodiment of the present invention, the rotating mechanism 5 includes a rotating gear 501 rotatably connected to the driving mechanism 6. The output end of the rotating gear 501 is connected to the input end of the bevel gear set 502. The output end of the bevel gear set 502 is coaxially fixedly mounted on the linkage shaft 503. A connecting block 504 is fixedly mounted on the surface of the linkage shaft 503. A sliding column 302 passes through the connecting block 504 and is slidably connected to the connecting block 504. The other end of the connecting spring 303 is connected to the connecting block 504. A fixed circular plate 404 is fixedly mounted on the connecting block 504. Two fixed support rods 505 are fixedly mounted on the surface of the connecting block 504. Each fixed support rod 505 is slidably connected to the fixed cylinder 202. The mounting frustum 103 is provided with inner ring teeth 506 and outer ring teeth 507 that cooperate with the rotating gear 501. A rotation damper is provided on the fixed support rod 505.

[0046] In practical applications, when the plasma tube 201 is driven to revolve by the driving mechanism 6, as in the embodiments of the present invention... Figure 6 , Figure 7 and Figure 8As shown, the rotating gear 501 rotates through the meshing of the outer ring teeth 507. This rotation of the rotating gear 501 then drives the connecting block 504 to rotate via the bevel gear set 502. The rotation of the connecting block 504, in turn, drives the fixed cylinder 202 to rotate via the fixed support rod 505. This, in turn, causes the plasma tube 201 to rotate closer to the central axis of the mounting frustum 103, moving the plasma tube 201 from a vertical to a horizontal position. Simultaneously, the rotating gear 501 at the symmetrical end rotates in the opposite direction through the meshing of the inner ring teeth 506, causing the symmetrical end to move in the opposite direction. The plasma tube 201 at the symmetrical end then moves away from the central axis of the mounting frustum 103, thus moving the plasma tube 201 from a horizontal to a vertical position. This automatic switching facilitates the later connection of the symmetrical end connector 204 to the power conduit 104.

[0047] like Figure 2 and Figure 3 As shown, in another preferred embodiment of the present invention, the driving mechanism 6 includes a drive motor 601 fixedly mounted on the mounting frustum 103. The output end of the drive motor 601 passes through the mounting frustum 103 and is rotatably connected to the mounting frustum 103. A main rotating disk 602 is fixedly mounted on the output end of the drive motor 601. A rotating gear 501 passes through the main rotating disk 602 and is rotatably connected to the main rotating disk 602. A linkage shaft 503 is rotatably connected to the main rotating disk 602.

[0048] In practical application, when the electromagnetic mechanism 3 is de-energized, the drive motor 601 starts to move. The operation of the drive motor 601 drives the main rotating disk 602 to rotate. The rotation of the main rotating disk 602 drives the plasma tube 201 to revolve through the rotating mechanism 5. Thus, during the switching of the plasma tube 201, the movement of the sealing mechanism 4 and the rotating mechanism 5 is triggered, thereby completing the protection of the docking head 204 and changing the attitude of the plasma tube 201.

[0049] like Figure 6 , Figure 7 and Figure 8 As shown, in another preferred embodiment of the present invention, the inner ring teeth 506 and the outer ring teeth 507 are arranged in a non-rotationally symmetrical manner.

[0050] In practical applications, the non-rotationally symmetrical arrangement of the inner ring teeth 506 and the outer ring teeth 507 ensures that the rotation of the plasma tube 201 and the symmetrical end plasma tube 201 will not occur simultaneously when the drive mechanism 6 revolves. This reduces the area occupied by the main rotating disk 602, improves the spatial flexibility of the mounting arm 101, and avoids spatial interference caused by the excessively large area of ​​the main rotating disk 602 when the mounting arm 101 moves.

[0051] like Figure 4 , Figure 5 and Figure 9 As shown, in another preferred embodiment of the present invention, the sliding semicircular sleeve 403 is made of elastic rubber, and a soft rubber pad is provided at the contact position between the plasma tube 201 and the fixing bolt 203.

[0052] In practical applications, the embodiments of the present invention, such as Figure 9 As shown, by making the sliding semicircular sleeve 403 a flexible rubber material, the two sliding semicircular sleeves 403 are prevented from contacting the connector 204 and causing hard friction, thus avoiding wear on the connector 204, when they move towards each other. Figure 5 As shown, a soft rubber pad is provided on the plasma tube 201 to prevent the fixing bolt 203 from exerting hard pressure on the surface of the plasma tube 201 when tightening the plasma tube 201, thus avoiding wear and scratches on the surface of the plasma tube 201.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
