Description

Technical Field

[0001] This utility model relates to a cleaning frame for a cleaning machine, specifically a cleaning frame for parts, which is applicable to a vacuum drying and cleaning machine. Background Technology

[0002] Currently, conventional parts are typically cleaned using specialized equipment such as through-feed cleaning machines to remove impurities such as oil stains, iron filings, and dust that adhere to the parts during processing. However, for parts with high cleanliness requirements or those requiring automation, conventional through-feed cleaning machines are often insufficient. For example, a clutch pressure plate produced on a separate production line cannot meet the automation requirements of a through-feed cleaning machine.

[0003] To meet cleaning requirements, these parts need to be cleaned separately using a vacuum drying and cleaning machine. For example, a multi-tank water washing and vacuum drying equipment (model KOUTA–CTW-4BV) produced by Wuxi Xinhongtian Environmental Protection Technology Co., Ltd. in China has the functions of cleaning, rinsing, rust prevention and vacuum drying. This equipment is a special cleaning machine for clutch pressure plates (hereinafter referred to as parts).

[0004] The cleaning frame that comes with this cleaning machine has a split design. Figure 1 The image shows a sub-basket of an existing cleaning frame. Figure 2 The image shows the mother basket of an existing cleaning frame. Figure 3 The diagram shows the existing cleaning frame with parts to be cleaned loaded into the sub-basket and mother basket. A, B, and C are the front view, side view, and top view, respectively. The working steps are as follows:

[0005] 1. Place the parts to be cleaned in the sub-basket and secure it; 2. Place the sub-basket in the mother basket and secure it; 3. Push the assembled cleaning frame to the fixed position, and the pneumatic robotic arm of the cleaning machine will pull the assembled cleaning frame into the cleaning machine for cleaning.

[0006] The existing cleaning frames have the following problems: the split structure is inconvenient for storage and use, increasing management costs; the steps for loading parts are cumbersome, the efficiency of loading parts into the frame is low and the operation is complicated.
