Description

Frame Clamping Mechanism of Pneumatic Glasses Assembly Machine

technical field

The utility model relates to a frame clamping mechanism of a pneumatic spectacles assembly machine, which can quickly realize the clamping of the spectacle frame and ensure that the spectacle frame is intact, can save labor and cost, and improve the spectacles assembly efficiency.

Background technique

In recent years, with the development of science and technology and the gradual improvement of people's living standards, people's needs for different types of glasses are becoming more and more diverse, and the market demand is large. However, at present, there is no automatic equipment for frame glasses assembly in China. Glasses manufacturers generally use manual assembly to connect the temples and frames of frame glasses with screws, which directly leads to increased labor costs and low production efficiency. The frame clamping mechanism of the automatic glasses assembly machine involved in the present invention is mainly used to solve the problem of precise clamping of the frames, which can realize fully automatic assembly and reduce labor costs.

Contents of the invention

In order to overcome the defects of high labor cost and low efficiency in the existing glasses assembly, the utility model provides a pneumatic glasses assembly that solves the assembly problem of the temples and frames of frame glasses, can realize fully automatic assembly, and reduces labor costs. Machine frame clamping mechanism.

The technical scheme that the utility model adopts is:

The frame clamping mechanism of the pneumatic glasses assembly machine is characterized in that it includes a frame clamp with a mold for placing the frame, a frame press block for pressing the frame into the frame clamp, a moving cylinder of the frame clamp, a frame stopper and a frame stopper Cylinder, one end of the moving cylinder of the picture frame fixture is fixed with a picture frame clamp; the side of the picture frame fixture away from the picture frame press block is provided with a picture frame stopper that cooperates with the picture frame press block, and the picture frame stopper It is connected with the cylinder of the picture frame stopper, and when assembled, the picture frame stopper is located at the discharge port at the front end of the mould.

Since the accuracy and speed of the clamping of the glasses parts are important indicators to measure the quality of the automatic glasses assembly machine, there is currently no fixture for the glasses parts in China. Therefore, the utility model adopts the form of a mold as a fixture for glasses, which solves the problem that the glasses are difficult to clamp due to irregular shapes. When working, the picture frame is transported into the picture frame fixture by the feeding mechanism, and the cylinder pushes the blocking piece and the pressing block successively to press the picture frame into the fixture. Regarding the selection of fixture materials, 3D printing technology can be used to achieve quick replacement and adapt to the characteristics of fast update of glasses; moreover, there are various types of printing and fast printing speed, which can adapt to the characteristics of short production cycle of glasses. The most important thing is that the printing cost is low, which can save the production cost of the enterprise and improve the economic benefits.

When the glasses need to be assembled, the frame is transferred into the frame fixture by the feeding mechanism. First, the cylinder of the frame stopper moves to push the frame stopper up to block the outlet at the front of the mould. Before the movement, fix the frame in the mold and wait for the temples to align with the holes of the frame. Then the cylinder of the frame stopper is retracted, the frame stopper returns to the initial position, the moving cylinder of the frame fixture is retracted, the frame pressing block returns to the initial position, and the frame falls from the discharge port at the front end of the mold. Ready for the next assembly.

The beneficial effects of the utility model are reflected in that: the precise clamping problem of the mirror frame can be solved, the fully automatic assembly can be realized, and the labor cost can be reduced.

Detailed ways

Referring to Figures 1 to 2, the frame clamping mechanism of the pneumatic glasses assembly machine includes a frame clamp 1 provided with a mold for placing the frame, a frame pressing block 2 for pressing the frame into the frame clamp 1, a moving cylinder 3 for the frame clamp, Picture frame stopper 4 and picture frame stopper cylinder 5, one end of described picture frame clamp mobile cylinder 3 is fixed with picture frame press block 2; The side far away from picture frame press block 2 on described picture frame clamp 1 is provided with a picture frame press block Cooperate with the picture frame stopper 4, the picture frame stopper 4 is connected with the picture frame stopper cylinder 5, and when assembled, the picture frame stopper 4 is located at the discharge port position at the front end of the mould.

Since the accuracy and speed of the clamping of the glasses parts are important indicators to measure the quality of the automatic glasses assembly machine, there is currently no fixture for the glasses parts in China. Therefore, the utility model adopts the form of a mold as a fixture for glasses, which solves the problem that the glasses are difficult to clamp due to irregular shapes. When working, the picture frame is transported into the picture frame fixture by the feeding mechanism, and the cylinder pushes the blocking piece and the pressing block successively to press the picture frame into the fixture. Regarding the selection of fixture materials, 3D printing technology can be used to achieve quick replacement and adapt to the characteristics of fast update of glasses; moreover, there are various types of printing and fast printing speed, which can adapt to the characteristics of short production cycle of glasses. The most important thing is that the printing cost is low, which can save the production cost of the enterprise and improve the economic benefits.

When spectacles need to be assembled, the picture frame is transferred into the picture frame clamp 1 by the feeding mechanism. First, the picture frame stopper cylinder 5 moves, and the picture frame stopper 4 is pushed upwards to block the mold front outlet, and then the picture frame fixture moves the cylinder 3, together with The picture frame pressing block 2 moves forward, the picture frame is fixed in the mould, and waits for the mirror legs to be aligned with the picture frame. Then the picture frame stopper cylinder 5 retracts, the picture frame stopper 4 gets back to the initial position, the picture frame fixture moving cylinder 3 retracts, the picture frame pressing block 2 gets back to the initial position, and the picture frame falls from the mold front end discharge port. Ready for the next assembly.

The picture frame is sent into the picture frame fixture by the feeding mechanism, the picture frame stop cylinder pushes the stop piece to move upward to prevent the picture frame from falling off, the picture frame fixture moving cylinder pushes the picture frame press block to move and the picture frame stop work together to clamp the picture frame.
