Description

Technical Field

[0001] The utility model relates to the technical field of processing single crystal silicon edge material, in particular to an edge material feeding device based on a robot. Background Art

[0002] The edge material is the edge waste cut from the edge of the round rod of monocrystalline silicon. These materials can be recycled in the production of photovoltaic single crystals. They have high silicon purity and are suitable for use with crystal pulling. The cleaned edge material needs to be glued and connected with a specific glue to form a continuous whole section of edge material, and then cut with diamond wire using existing cutting equipment. The edge material obtained by cutting is sent for degumming treatment.

[0003] Before cutting, the edge leather needs to be clamped from the box by an industrial robot using a clamp and then placed in a diamond wire cutting machine for cutting. However, the processing time of the diamond wire cutting machine and the back-end degumming equipment is different, resulting in the edge leather can only be loaded according to the cutting speed of the front-end diamond wire cutting machine; after the industrial robot waits for the cutting to be completed, it grabs the cut edge leather to the back-end degumming equipment; if the cut edge leather is directly put into the degumming equipment at this time, the degumming equipment needs to continue to run to complete the degumming of the edge leather, but the load of the degumming equipment is relatively low at this time, and the diamond wire cutting machine is still cutting the next piece of edge leather. The industrial robot did not reasonably utilize the equipment operation interval time during the processing process, resulting in the back-end degumming equipment running at low load or even running idle. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a robot-based edge material feeding device, which is arranged between the cutting section and the cleaning and degumming section to temporarily store the cut edge materials. After the industrial robot completes cutting and placement at the front end, it puts the cut edge materials at the rear end into the degumming equipment for processing. The amount of temporarily stored edge materials meets the requirement of the degumming equipment to run at close to full load, avoiding the situation where the degumming equipment runs at low load, so that the industrial robot can adapt to the production rhythm of the diamond wire cutting machine and the degumming equipment at the rear end.

[0026] like Figure 3-4 As shown, a clamping cylinder 5 is horizontally fixed to the bottom of the positioning frame 1; the telescopic end of the clamping cylinder 5 is fixed to the bottom of the push plate 3; further, in order to ensure the stability of the movement of the push plate 3, the telescopic end of the clamping cylinder 5 is fixedly connected to the push plate 3 through a connecting member 7; the connecting member 7 is an L-shaped plate structure; a slide groove 7.1 is provided at the bottom of the connecting member 7; a slide rail 8 is provided on the inner side of the support 2 corresponding to the slide groove 7.1; the connecting member 7 moves along the slide rail 8 through the slide groove 7.1.

[0027] like Figure 2 , 4 As shown, the body of the push plate 3 is provided with more than one buffer 4, which can prevent the edge leather 12 from being damaged when the cylinder is clamped, and play a buffering role. The buffer 4 corresponds to the notch 1.2, and moves from the edge of the notch 1.2 to the inside of the notch 1.2 to clamp and position the edge leather 12. Specifically, the buffer 4 includes: a pressure block 4.1, a movable rod 4.2, a spring 4.3, and a baffle 4.4; a sleeve 4.5 is fixed to the back of the push plate 3, and the movable rod 4.2 passes through the push plate 3 and retracts along the sleeve 4.5; a spring 4.3 is sleeved on the rod body of the movable rod 4.2 located on the front of the push plate 3; a pressure block 4.1 is fixed to the head end of the movable rod 4.2; a rubber pad is covered on the pressure block 4.1; a baffle 4.4 larger than the sleeve 4.5 is fixed to the end of the movable rod 4.2; the push plate 3 is symmetrically provided with two groups, each group is provided with two push plates 3; each push plate 3 corresponds; the two groups of push plates 3 ensure relative stability during clamping and positioning to avoid deflection.
