The second doctor blade 252 is located on the bypass path of the first transfer belt 21 with respect to the upstream portion of the feeding port 31 and is adjacent to the conveying path. In addition, in FIG. 7, in order to clearly express the relationship between the components, the positioning member 231 is not shown in a sectional view. As shown in FIG. 8, the second scraper blade 252 abuts between the first transfer belts 21 so that there is no gap therebetween. Therefore, the remaining paint on the first transfer belt 21 that is not adhered to the screws A can be applied.

The third blade 253 is adjacent to the second transfer belt 22 and is located on a bypass section of the second transfer belt 22 in a downstream section with respect to the conveyance path and adjacent to the conveyance path. In this embodiment, the third blade 253 is fixed to the positioning member 231 of one of the pressure roller units 230. Therefore, even if the second transfer belt 22 moves with the pressure roller unit 230, the third blade 253 and the second transfer belt 22 The relative position between the two remains unchanged. As shown in FIG. 9, the third scraper blade 253 leans between the second transfer belts 22 so that there is no gap between them. The above-mentioned upstream section refers to a person who is located in a front position relative to a component in the direction of the transfer belt bypass, and a downstream section is located in a rear position relative to a component.

For example, the number of the collecting troughs is equal to the number of the scrapers, and is located below each scraper. In this embodiment, there are two aggregate tanks, which are a first aggregate tank 261 and a second aggregate tank 262, respectively. The first collecting tank 261 is located under the first scraper 251 and the second scraper 252, and the second collecting tank 262 is located under the third scraper 253.

Please refer to FIG. 2 and FIG. 6. During the coating process, the screw A is conveyed by the conveying assembly 10 and sequentially enters between the first transfer belt 21 and the second transfer belt 22 along the conveying path, and is conveyed by the first and second transfer belts 21 and 22 Holding. At the same time, because the feeding port 31 of the feeding assembly 30 continues to spray paint to the outside of the first transfer belt 21 and the power mechanism 211 drives the first transfer belt 21 to bypass, the entire outside of the first transfer belt 21 is Coating will be applied to transfer to the screw A in contact.

The second transfer belt 22 clamps the screw A between the second transfer belt 22 and the first transfer belt 21 through the pressure roller group 23. In this embodiment, the direction of travel of the screw A is from right to left, and the first transfer belt 21 is driven counterclockwise by the power mechanism 211, and the speed of the first transfer belt 21 is not equal to the speed of the screw A The speed of travel, so the first transfer belt 21 can drive the screw A to rotate, so that the paint can be coated on the screw A for a complete circle.

In addition, through the first blade 251 located downstream of the feeding port 31, if too much paint on the first transfer belt 21 is scraped off by the first blade 251, so that the paint on the first transfer belt 21 before the transfer The amount remains stable. And through the second scraper blade 252 located upstream of the feeding port 31, the remaining paint on the first transfer belt 21 can be scraped off to keep the paint fresh. The paint scraped off by the first scraper 251 and the second scraper 252 will flow down to the first collecting tank 261.

During the transfer process, since the pressing roller unit 230 pushes the second transfer belt 22 in the direction of the first transfer belt 21, the paint can be squeezed into the screw while the screw A is clamped, without the paint and the Gaps between the threads. Since the second transfer belt 22 will contact the screw A, the second transfer belt 22 will be driven by the screw A to turn clockwise, and will also adhere to the coating material originally applied to the screw A, and the third blade 253 That is, the paint adhered to the second transfer belt 22 is scraped off, and the scraped paint will flow down to the second collecting tank 262.

In addition, in this embodiment, the straight section of the second transfer belt 22 may have a wave-like deformation phenomenon during the transportation process. Specifically, when the screw A approaches the pressure roller unit 230 of the pressure roller group 23, the elastic member 233 of the pressure roller unit 230 rotates the positioning member 231 and causes the pressure roller 232 to lean against the first transfer belt 21. At this time, the first The distance between the transfer belt 21 and the second transfer belt 22 is minimized. When the screw A passes through the second transfer belt 22 and abuts against the pressing wheel 232, the pressing wheel 232 presses the screw A. Since the conveying assembly 10 continuously drives the screw A to move, the screw A will instead push the pressing wheel 232 to rotate clockwise along the moving direction of the screw A, so the second transfer belt 22 is away from the first transfer belt 21. When the screw A pushes the pressing wheel 232 to rotate so that the distance between the second transfer belt 22 and the first transfer belt 21 is equal to the diameter of the screw body, the screw A is released from the pressing wheel 232, and then the pressing wheel 232 leans again The first transfer belt 21 can press the next screw A that is moved closer. Therefore, when the plurality of screws A are conveyed between the plurality of pressure roller units 230, the straight section of the second transfer belt 22 is wavy when the screws A move closer to the pressure rollers 232, and when the screws A are released from the pressure rollers 232 At this time, the straight section of the second transfer belt 22 is straight.

In summary, during the coating process of the screw A, the second transfer belt 22 is pushed toward the first transfer belt 21 by the pressing roller unit 230, so the screw A will be clamped on the first transfer belt. 21 and the second transfer belt 22 are driven to rotate by the first transfer belt 21, so that the paint adhered to the first transfer belt 21 can be transferred to the screw A and can cover the screw A for a complete cycle. By pressing the screw A through the second transfer belt 22, the paint can be squeezed into the screw teeth, so there is no gap between the paint and the screw teeth.
