[0001] This utility model relates to the field of automotive parts processing technology, specifically to an automotive parts spraying suspension device. Background Technology

[0002] In the painting process of automotive parts, the parts need to be fixed and suspended on suspension devices for painting operations. Common types of suspension devices include chain suspension and rotary hook suspension. Chain suspension devices use a conveyor chain as the main load-bearing and transporting component. Multiple mounting stations are set on the chain, each connecting to a suspension element, such as a hook. A drive unit moves the chain in a circular motion, thus achieving the suspended transport of automotive parts. Rotary hook suspension devices feature rotatable hooks connected to the suspension frame via bearings and other components, allowing them to rotate under the drive of a motor or other drive unit.

[0003] Existing suspension devices have certain limitations; they can only be used for suspended conveying or for rotary spraying, but cannot be used for rotary spraying during suspended conveying. Utility Model Content

[0026] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0027] like Figures 1-3 As shown, this utility model embodiment provides an automotive parts spraying suspension device, including a linear transmission mechanism 100, a rotating shaft 200, a rotating motor 300, and a lifting mechanism 400.

[0028] The linear transmission mechanism 100 is equipped with a moving block 110. The linear transmission mechanism 100 can be a chain conveyor or a belt conveyor.

[0029] The rotating shaft 200 is rotatably connected to the moving block 110. The upper end of the rotating shaft 200 is provided with a toothed groove 210, and the lower end of the rotating shaft 200 is provided with a hanger 220.

[0030] The rotary motor 300 is located above the linear transmission mechanism 100. The lower end of the rotary motor 300 is provided with an output shaft, and a gear 310 adapted to the tooth groove 210 is coaxially fixed at the lower end of the output shaft.

[0031] The lifting mechanism 400 is used to drive the rotary motor 300 to lift and lower, so that the gear 310 can be inserted into or removed from the tooth groove 210.

[0032] During spraying, the automotive parts to be sprayed are fixed on the bracket 220. The linear transmission mechanism 100 drives the bracket 220 to move to the spraying station. At this time, the gear 310 at the lower end of the rotary motor 300 is aligned with the tooth groove 210 at the upper end of the rotary shaft 200. The lifting mechanism 400 drives the rotary motor 300 to move downward, so that the gear 310 is inserted into the tooth groove 210. Then, the bracket 220 can be rotated by the rotary motor 300, thereby performing rotary spraying on the automotive parts on the bracket 220. After the spraying is completed, the rotary motor 300 is driven to move upward by the lifting mechanism 400, so that the gear 310 is disengaged from the tooth groove 210. Finally, the bracket 220 is transported away from the spraying station by the linear transmission mechanism 100. In this way, rotary spraying can be carried out during the suspension and transportation of automotive parts.

[0033] In some embodiments, a track groove 500 is provided on the upper side of the linear transmission mechanism 100 and extends along the linear transmission mechanism 100. A slot 510 is provided on the lower side of the track groove 500 along the length direction. The upper end of the rotating shaft 200 passes through the slot 510 and is provided with a rotating slider 320 adapted to the track groove 500. A toothed groove 210 is provided on the rotating slider 320. The track groove 500 has a guiding effect on the upper end of the rotating shaft 200, which can improve the stability of the hanger 220.

[0034] In some embodiments, in order to improve the stability of the lifting of the rotary motor 300, a bracket 520 is provided at the top of the track groove 500, a vertical guide rail 521 is provided on the bracket 520, a motor base 522 is slidably mounted on the vertical guide rail 521, the rotary motor 300 is fixed on the motor base 522, a gear 310 is provided in the track groove 500, and the output shaft of the rotary motor 300 passes through the through hole at the top of the track groove 500 and is connected to the gear 310.

[0035] The lifting mechanism 400 includes a telescopic push rod, which can be an electric telescopic push rod. The telescopic push rod is located above the motor base 522 and fixed on the bracket 520. The telescopic push rod extends downward and is connected to the motor base 522.

[0036] In some embodiments, the bracket 220 is detachably connected to the lower end of the rotating shaft 200, which facilitates the replacement of different types of brackets 220 and improves applicability. Specifically, the upper end of the bracket 220 is provided with a first threaded joint 221, and the lower end of the rotating shaft 200 is provided with a second threaded joint 230 that is threadedly connected to the first threaded joint 221.

[0037] In some embodiments, the hanger 220 includes a central rod 222 and multiple sets of product mounting parts 223 disposed around the central rod 222. The upper end of the central rod 222 is connected to the lower end of the rotation shaft 200. By providing multiple sets of product mounting parts 223, automotive parts to be painted can be fixed on each set of product mounting parts 223. In this way, during the rotation of the hanger 220, the outer surface of the automotive parts can be painted, thereby increasing the number of automotive parts that can be painted.

[0038] Understandably, the 220 mount can also be a single-product mount structure, which is suitable for automotive parts that require surrounding painting.

[0039] In some embodiments, a photoelectric sensor 600 for detecting the tooth groove 210 is provided on the lower side of the gear 310. By setting the photoelectric sensor 600, the hanger 220 can be moved to the spraying station for detection, ensuring that the gear 310 and the tooth groove 210 are accurately aligned.
