Description

Technical Field

[0001] The utility model relates to the technical field of optical glass cleaning, in particular to a perforated plate. Background Art

[0002] A perforated plate, usually used to cut PET (polyethylene terephthalate) film or other types of film materials. In the eyewear manufacturing industry, PET film is used as a protective layer for lenses to prevent scratches or damage to the lenses during processing. PET film can be attached with a UV (ultraviolet) protective layer to block harmful ultraviolet rays and protect the eyes from ultraviolet damage. In a variety of industrial products, PET film is used in film lamination processes to provide additional protection or decorative effects. The design of the perforated plate allows users to cut holes of specific sizes and shapes as needed to meet the specific requirements of different products or components. By using a perforated plate, the efficiency, accuracy and consistency of the cutting process can be improved, while reducing material waste and saving costs;

[0003] The glass on the lens module of electronic products such as mobile phones and notebooks needs to be cleaned after the whole piece of optical glass is cut into small pieces. Since the single small piece of optical glass is small in size and thin in thickness, in order to improve production efficiency, the whole piece of cut glass is attached to a steel ring with UV film for cleaning. After cleaning and drying, the steel ring with UV film can be removed by UV decontamination to remove the glass on the UV film.

[0004] The shortcomings of the above solution are: the existing steel rim cleaning method is to attach UV film to the entire steel rim, and UV film is expensive. If the entire steel rim is covered with UV film and only part of the area is actually used to fix the glass, the unused UV film will be wasted and the overall material cost will increase. It may require more delicate operations to evenly attach UV film to the entire steel rim, which may increase the difficulty of operation and the risk of errors, increase the steps in the production process, and thus affect the technical problem of production efficiency. Utility Model Content

[0005] The utility model aims to provide a perforated plate to solve the problem in the prior art that the existing steel ring cleaning process is to attach a UV film to the entire steel ring. The UV film is expensive. If the entire steel ring is covered with the UV film and only a partial area is actually used to fix the glass, the unused UV film will be wasted and the overall material cost will increase. Evenly attaching the UV film to the entire steel ring may require more delicate operations, which may increase the difficulty of operation and the risk of errors, increase the steps in the production process, and thus affect the technical problem of production efficiency.

[0006] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0007] A perforated plate, comprising a main plate;

[0008] The main plate is provided with a groove mechanism, and the groove mechanism is divided into a first groove, a second groove, and a third groove. The first groove and the second groove are arranged inside the third groove, and the first groove is arranged inside the second groove. The main plate is provided with a first side edge, and a positioning column is provided on the first side edge. The main plate is provided with a third side edge, and an L-shaped positioning block is provided on the third side edge.

[0009] As a further solution of the utility model: the main body plate is made of stainless steel.

[0010] As a further solution of the utility model: the groove mechanism is located at the center of the main plate.

[0011] As a further solution of the utility model: the first groove, the second groove and the third groove are connected to each other.

[0012] As a further solution of the utility model: the positioning column and the L-shaped positioning block are fixed on the surface of the main plate by welding.

[0013] As a further solution of the utility model: the positioning column and the L-shaped positioning block are arranged on two opposite sides of the main plate.

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model places the steel ring with the PET film attached to it at an angle in the L-shaped positioning block, aligns the V-shaped notch on one side of the steel ring with the two positioning columns, and uses a blade to cut along the corresponding groove according to the actual required cutting size, so as to cut out a hole of the required size of the PET film. After the steel ring is taken out, the UV film is attached to the PET film to cover the hole on the PET film of the steel ring. The PET films on multiple steel rings can be cut at the same time without processing them one by one, which greatly improves the production efficiency. Through precise cutting, the amount of UV film is reduced, thereby saving material costs.

[0016] 2. After positioning, stacking and placing the steel rings, the PET films on multiple steel rings can be cut at the same time, which improves production efficiency. Through precise cutting, the amount of UV film used is reduced, thereby saving costs. The positioning columns and L-shaped positioning blocks are fixed to the main plate by welding to ensure the accurate positioning of the steel rings, thereby significantly improving the efficiency of the production line. Accurate positioning ensures that the PET film on each steel ring can be accurately cut, reducing size deviation and scrap rate. The design of the positioning columns and L-shaped positioning blocks simplifies the operation process, allowing the operator to quickly and accurately place and position the steel rings, reducing the difficulty of operation.
