Description

Technical Field

[0001] This utility model belongs to the field of vehicle door painting technology. Specifically, this utility model relates to a paintable vehicle door spare parts frame. Background Technology

[0002] Currently, after-sales spare parts in domestic automotive painting workshops are installed on spare parts frames for production. However, after electrophoresis, door spare parts require adhesive application, and most spare parts frames are not designed to accommodate on-line adhesive application. After electrophoresis, spare parts need to be manually disassembled and then adhesive applied before being installed back onto the spare parts frame. This manual loading and unloading of spare parts takes a long time, affecting production efficiency and manufacturing energy consumption.

[0003] A patent application with patent number 202211231811.3 and publication date of April 18, 2023, discloses a combined electrophoretic coating fixture and system for vehicle body spare parts. The system includes: a support member with multiple hanging holes spaced apart; and spare part hooks with both ends bent to one side, one end of which is hung in the hanging holes, and the other end used to suspend the vehicle body spare parts. By spaced-aparting multiple spare part hooks on the support member, the spare part can be suspended in a spare part frame for electrophoresis. This saves time and effort in hanging and removing parts, minimizes contact between parts, results in good electrophoresis quality, reduces paint repair rates, minimizes collisions between parts, reduces sheet metal defects, and lowers sheet metal repair rates. Removal is simple; the part or hook can be removed, ensuring high safety. The hooks can be reused multiple times, reducing costs. When the size of the vehicle body spare part does not change significantly, the fixture can be fixed in the spare part frame without disassembly. After removing the electrophoretically coated spare part, it can be directly transported with the spare part frame to the welding workshop for reuse, reducing labor costs.

[0004] In the existing technology, manual disassembly and installation is labor-intensive and time-consuming, with each part estimated to take 5 minutes. After manual disassembly, the car door needs to be placed on a special glue applicator for manual glue application, which is inconvenient. The long manual operation time leads to production line downtime and increased manufacturing costs. Utility Model Content
