[0002] Due to the complex structure of automotive parts, it is not possible to apply a paint film to the interior of the parts. Instead, the surface is usually treated with an electrophoretic coating process. The electrophoretic coating process for automotive parts requires multiple process steps. Throughout the process, the parts are always mounted on a rack and transported between the processing equipment in the process flow by a conveyor.

[0003] In the related art, the existing conveyor track cannot accurately determine whether the automobile parts have reached the end of the conveyor track when in use. If the transmission motor of the track continues to run when the automobile parts reach the end of the conveyor track, it is easy to cause the automobile parts to rush out of the track, thereby causing damage to the automobile parts. For this reason, we propose a automobile painting paint rail conveyor device.

[0004] The above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute prior art. Utility Model Content

[0022] Reference Figure 1 、 2 3. A paint rail conveying device for automobile coating, comprising a bracket 1, a transmission track 2, a transmission belt 5 and an adjustment plate 17. Three sets of transmission tracks 2 are installed at horizontal intervals on the upper end of the bracket 1. A transmission belt 5 is installed inside the transmission track 2. A driving roller is installed on the inner side of the left end of the transmission belt 5. The front end of the driving roller is integrally formed with a rotating shaft, which passes through the transmission track 2. A driven gear 9 is fixedly installed on the side of the front end of the rotating shaft. The lower end of the driven gear 9 is meshed with a driving gear 8. A transmission shaft is welded at the center of the lower end of the driving gear 8. The lower end of the transmission shaft is connected to the upper output end of the transmission motor 7. The transmission motor 7 is detachably fixed on the upper end of the mounting plate 6. The mounting plate 6 is detachably connected to the front end of the transmission track 2 by bolts. The lower ends of the front and rear transmission tracks 2 are opposite to each other on the left and right sides. It is said that an adjustment plate 17 is provided, which is welded and fixed to the upper end of the bracket 1. A screw 19 is provided for the internal rotation of the adjustment plate 17. One end of the screw 19 passes through the adjustment plate 17 and is connected to the output end of the adjustment motor 10 on the side of the adjustment plate 17. The side thread engagement of the screw 19 is provided with a mounting block. The upper end of the mounting block is welded with a connecting plate 18. The connecting plate 18 is detachably connected and fixed to the lower end face of the transmission track 2 by bolts. The driving gear 8 is rotated by the transmission motor 7. The driving gear 8 and the driven gear 9 are both helical gears. The driven gear 9 rotates accordingly, driving the active roller and the transmission belt 5 to work, thereby realizing the transmission of automotive parts. By adjusting the plate 17 and the adjustment motor 10, the adjustment motor 10 is a synchronous motor. The spacing between the transmission tracks 2 can be adjusted to meet the transmission requirements of components of different specifications.

[0023] When the embodiments of the present invention are implemented, Figure 1 、 3 As shown, the front and rear ends of the bracket 1 are symmetrically welded with support cross bars 3 horizontally, the upper ends of the support cross bars 3 are symmetrically welded with fixing seats 15, and guide rods 16 are welded and fixed between the fixing seats 15. The lower ends of the front and rear end transmission tracks 2 are integrally formed with guide blocks 20 at the corresponding positions of the guide rods 16. The guide rods 16 pass through the guide blocks 20. The guide rods 16 and guide blocks 20 ensure the stability of the transmission track 2 during adjustment and avoid deviation.

[0024] When the embodiments of the present invention are implemented, Figure 1 、 2 As shown, L-shaped fixing plates 11 are symmetrically integrally formed at the left and right ends of the transmission track 2. A telescopic sleeve 12 is fixedly provided on the side of the L-shaped fixing plate 11 close to the transmission track 2. A buffer plate 14 is connected to the end of the telescopic sleeve 12 close to the transmission track 2. A pressure sensor 13 is installed in the gap of the telescopic sleeve 12 of the L-shaped fixing plate 11. The buffer plate 14 is a flexible rubber plate. When the component is transmitted to the end, a buffering operation is performed through the telescopic sleeve 12 and the buffer plate 14. A buffer spring can be set in the telescopic sleeve 12 to prevent the component from rushing out of the track and preventing damage to the component.

[0025] When the embodiments of the present invention are implemented, Figure 1 、 3 As shown, one end of the screw 19 passes through the adjustment plate 17, and a locking nut 21 is provided on the side of the screw 19. A controller 4 is fixedly installed on the upper end of the supporting cross bar 3. When the component is transmitted to the end and the operator still does not stop the conveyor belt 5, the pressure sensor 13 is squeezed. When the value of the pressure sensor 13 reaches the threshold, the controller 4 controls the transmission motor 7 to stop working to prevent the component from rushing out of the track and being damaged.

[0026] In this embodiment, the components are all universal standard parts or components known to those skilled in the art, and their structures and connection principles are all known to those skilled in the art through technical manuals or conventional experimental methods. After the device is installed, according to the specifications of the automobile parts to be transmitted, the screw 19 is driven to rotate by adjusting the motor 10, so that the mounting block moves along the screw 19, thereby adjusting the spacing between the three sets of transmission rails 2. After the adjustment is completed, the locking nut 21 is tightened to fix the position, and the guide block 20 of the transmission rail 2 slides along the guide rod 16 to ensure that it remains stable and does not deviate during the adjustment process; the automobile parts are placed on the conveyor belt 5 and are ready for transportation; the transmission motor 7 is started, and its output end drives the driving gear 8 to rotate through the transmission shaft. The driving gear 8 is engaged with the driven gear 9, prompting the driven gear 9 and the rotating shaft integrally formed therewith to rotate, and the rotating shaft drives The active roller rotates, thereby pushing the conveyor belt 5 forward and transporting the automobile parts to the paint or coating area; when the automobile parts reach the end of the transmission track 2, they first contact the telescopic sleeve 12 and the buffer plate 14 made of flexible rubber material. These components can absorb impact force and protect the parts from damage. If the parts continue to move forward, they will squeeze the pressure sensor 13 on the L-shaped fixing plate 11; when the pressure value detected by the pressure sensor 13 reaches the preset threshold, the controller 4 receives the signal and immediately controls the transmission motor 7 to stop working to prevent the parts from being damaged or rushing out of the track due to excessive squeezing; after the conveyor belt 5 stops, the operator can safely unload the parts that have been processed and load new parts to be processed, and then repeat the above process to continue the next cycle of operation. The fixing components of the body parts adopt a conventional structure fixed by paint, which is not specifically limited in this application.
