AI Technical Summary
Existing technology for spraying 3U chassis top covers uses a single hanging method with double V hooks, resulting in low production efficiency, complex processes, high labor costs, and a tendency to miss processes and produce defective products. Removing burrs from the mesh area is also time-consuming.
Design a spraying fixture for a 3U chassis top cover, including a hanging rod, hooks and a frame. The frame is a square frame formed by an upper plate, a lower plate, a left side plate and a right side plate. Baffles are set between the mesh holes. Multiple frames can be sprayed with multiple products at the same time. The baffles prevent powder from entering the interior of the chassis and avoid the use of masking tape.
It reduces processes, lowers labor costs, increases yield, improves spraying efficiency, avoids the need for patching hook marks and rough edge treatment, saves labor costs, and allows multiple products to be sprayed at once.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of mounting technology, specifically to a spraying mounting fixture for a 3U chassis cover. Background Technology
[0002] Powder coating in a spray painting plant refers to a coating process that uses corona discharge to adhere powder coatings to a workpiece. After powder coating, a heat coating process is completed. The main process involves fixing the product onto a fixture before powder coating; however, for products such as… Figure 1 When powder coating the back cover of the wireless access point shown, the existing double V-hooks can only be used for single-suspension installation. Furthermore, masking tape must be applied before coating to prevent powder coating of unwanted areas. After coating, the masking tape must be removed, rough edges trimmed, and hook marks repaired. This process is lengthy and labor-intensive. Single-suspension installation is inefficient and prone to missed steps or defects. Additionally, the numerous mesh openings make cleaning burrs from inside the openings time-consuming. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spraying fixture for the top cover of a 3U chassis.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a spraying fixture for a 3U chassis cover, comprising a hanging rod, a hook, and a frame disposed on the hanging rod and cooperating with the 3U chassis cover. The frame comprises a square frame formed by an upper plate, a lower plate, a left side plate, and a right side plate. The hanging rod is connected through the center of the upper plate and the lower plate. Two upper baffles are respectively disposed on each side of the front and rear ends of the upper plate, and the two upper baffles on each side are isolated between the upper mesh openings of the 3U chassis cover. Two side baffles are respectively disposed on each side of the front and rear ends of the left and right side plates, and the two side baffles on each side are isolated between the left and right mesh openings of the 3U chassis cover.
[0005] In some embodiments, the spacing between the two upper baffles on each side, and the spacing between the two side baffles on each side, are adjusted according to the corresponding mesh width on the 3U chassis cover.
[0006] In some embodiments, reinforcing ribs are provided at the front and rear ends of the bottom of the lower plate.
[0007] In some embodiments, the hanging rod is provided with two frames arranged vertically, and each frame can be provided with a 3U chassis cover at its front and rear ends.
[0008] Compared with the prior art, the beneficial effects of this utility model are: when applied to the powder coating of the 3U chassis cover, it can avoid the need to apply masking tape, reduce labor costs, reduce processes, improve yield, and avoid the processes of patching hook marks and trimming rough edges, thus saving labor costs.
[0009] The setting of the plurality of frame bodies can spray a plurality of products at a time, reduces working hours, and improves spraying efficiency;
[0010] The setting of the baffle can effectively block the powder from entering the 3U box body (shielding area), and has a gap with the product, so that the product mesh hole is not caused to accumulate powder and form a burr.
[0011] Details of one or more embodiments of the present application are presented in the following drawings and description to make other features, objects and advantages of the present application more clear, concise and easy to understand, and to make the present application more fully described and understood through the embodiments of the present application.
