Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing, and in particular relates to a cleaning device for automobile roller surfaces. Background Technology

[0002] When fitting two steel or aluminum plates together, such as for car doors, hoods, and tailgates, a six-axis robot uses steel rollers to press the outer edges, causing the outer edges of the two plates to be rolled together. This process is called roller edging. Before pressing, sealant is applied to the outer edges of the two plates. This sealant is squeezed out during pressing and sticks to the rollers, requiring constant cleaning of the sealant from the rollers.

[0003] However, in existing technologies, fixed-position scrapers are generally used to remove adhesive from the roller surface, which reduces cleaning efficiency and makes it difficult to ensure the comprehensiveness and thoroughness of the roller surface cleaning. Therefore, a new device needs to be designed. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle roller surface cleaning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vehicle roller surface cleaning device includes several roller bodies and a suspension device for fixed suspension movement, and a frame device for supporting dual-station rotation. Two scraping devices for telescopically scraping off surface adhesive are symmetrically mounted on the frame device. The suspension device is installed at one end of the frame device. The frame device includes a frame body with a fixed frame. A drive assembly for providing power for dual-station rotation is mounted on the fixed frame, and a waste box is placed below the fixed frame. The suspension device includes a fixed base with a folding robotic arm mounted on it. A swing frame is mounted at the top of the folding robotic arm, and a first motor is mounted on the swing frame. A clamping assembly for rotating the roller bodies is mounted at the output end of the first motor. Each scraping device includes a support frame with a telescopic cylinder mounted on it. A translation frame is mounted at the telescopic end of the telescopic cylinder, and a scraper plate is slidably mounted at the bottom of the translation frame. An adjustment assembly for elastic clamping is provided between the scraper plate and the translation frame.

[0007] Furthermore: the drive assembly includes a speed reducer, a second motor is installed at one end of the speed reducer, two output shafts are symmetrically arranged on both sides of the speed reducer, and two transmission columns are symmetrically arranged on the outer end face of the output shaft.

[0008] Furthermore, the outer end face of the output shaft protrudes from the side of the fixing frame.

[0009] Furthermore, the clamping assembly includes a rotating shaft, and several support shafts are evenly distributed around the bottom circumference of the rotating shaft.

[0010] Furthermore, four support shafts are provided, and they are perpendicular to the rotation axis.

[0011] Furthermore, the adjustment assembly includes a limiting slide rod fixedly installed on the scraper plate, the limiting slide rod is provided with a compression spring, the limiting slide rod is arranged parallel above the scraper plate and slides through the translation frame.

[0012] Furthermore, the end of the scraper is provided with a contoured groove.

[0013] Compared with existing technologies, the beneficial effects are:

[0014] 1. Through the symmetrical arrangement of the scraping device and the dual output shaft drive structure, the two roller bodies can be cleaned alternately at the same time, which significantly improves the cleaning efficiency (dual-station rotation of the transmission column + automatic repositioning of the clamping assembly); through the coordinated design of robotic arm positioning, dual-station synchronous drive and elastic scraping, the problems of low efficiency and poor adaptability in traditional cleaning are solved, which is especially suitable for the rapid cleaning needs of large batches of rollers in automobile manufacturing.

[0015] 2. The folding robotic arm of the suspension device works in conjunction with the swing frame to achieve automatic positioning and horizontal maintenance of the rollers, ensuring stable contact with the transmission columns; the first motor drives the clamp assembly to rotate and switch rollers, and the second motor drives the transmission columns on both sides synchronously through the reducer, reducing manual intervention;

[0016] 3. The contoured groove of the scraper blade matches the roller profile, and combined with the elastic adjustment component (compression spring + limit slide bar), it dynamically adapts to the roller surface under different wear conditions, ensuring that the glue is scraped off thoroughly without damaging the substrate; the telescopic cylinder controls the scraping pressure to avoid overload;

[0017] 4. The waste box is integrated under the fixed frame, covering the dual-station area, directly collecting the scraped adhesive and avoiding pollution of the working environment; the frame device integrates the drive component and waste collection function, reducing the equipment footprint; the adhesive scraping device and the suspension device can operate independently, facilitating maintenance or replacement of parts.

There are four support shafts 206, which are perpendicular to the rotating shaft 205. The fixed base 201... 1. Installed on the frame 101, the folding robotic arm 202 drives the swing frame 203 to move, always horizontally, so that the end face of the roller body 4 on the support shaft 206 on one side of the bottom of the rotating shaft 205 presses against the end face of the transmission column 107. The roller body 4 rotates under the drive of the transmission column 107 to complete the cleaning.
