Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic crystalline silicon plate processing, in particular to a wire welding machine for photovoltaic crystalline silicon plates with automatic positioning. Background Art
[0002] In the processing of photovoltaic crystalline silicon plates, the raw materials are first produced into two types: single crystal silicon rods and polycrystalline silicon ingots. The single crystal silicon rods go through steps such as grinding and cutting to produce single crystal square rods, and then are divided into single crystal silicon wafers. The single crystal silicon wafers can be processed into single crystal battery chips and then assembled into single crystal modules; the polycrystalline silicon ingots go through steps such as grinding and cutting to produce polycrystalline square rods, and are divided into polycrystalline silicon wafers. The polycrystalline silicon wafers can be processed into polycrystalline battery chips and then assembled into polycrystalline modules; the production cost of single crystal modules is higher than that of polycrystalline modules.
[0003] During the production and manufacturing of photovoltaic crystalline silicon plates, it is necessary to align two photovoltaic crystalline silicon plates for wire welding to connect the two photovoltaic crystalline silicon plates into a whole. Most of the existing wire welding devices for photovoltaic crystalline silicon plates mainly place the two photovoltaic crystalline silicon plates on the wire welding platform by manual placement and then manually align them. Since the photovoltaic crystalline silicon plates are relatively thin, they are easily damaged during the manual alignment process. And during the wire welding process, it is necessary to contact the photovoltaic crystalline silicon plates, which easily causes displacement of the photovoltaic crystalline silicon plates, resulting in offset of the welding position and damage to the photovoltaic crystalline silicon plates, reducing the work efficiency. It is necessary to design a wire welding machine for photovoltaic crystalline silicon plates with automatic positioning to solve the above-mentioned problems. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a wire welding machine for photovoltaic crystalline silicon plates with automatic positioning.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A wire welding machine for photovoltaic crystalline silicon plates with automatic positioning includes a fixed frame. Both the front and rear ends on the right side of the fixed frame are fixedly connected with motors. The rotating shafts of the motors are fixedly connected with threaded rods. The outer sides of the threaded rods are threadedly connected with moving frames. The upper ends of the moving frames are fixedly connected with connecting frames. The bottom ends of the inner sides of the connecting frames are fixedly connected with support frames. The middle part of the upper end of the fixed frame is fixedly connected with an installation frame. The bottom ends of the front and rear ends of the inner side of the installation frame are fixedly connected with limit blocks. A positioning slot is arranged in the middle of the upper end of the fixed frame; the moving frames, connecting frames and support frames are used to place the photovoltaic crystalline silicon plates and drive the photovoltaic crystalline silicon plates to move left and right to butt the edges of the photovoltaic crystalline silicon plates; the installation frame is used to fixedly install the limit blocks and the wire welding device;
[0007] Through the above technical solution, the two photovoltaic crystalline silicon plates to be welded are respectively placed on the upper part of the support frame for fixation, and the welding edges are aligned with the edges of the connecting frame. Then, the motor drives the threaded rod to rotate, driving the front moving frame to move to the right and the rear moving frame to move to the left. When the moving frame moves to the bottom of the mounting frame, the right end of the front connecting frame contacts the left side of the front limiting block, and the left end of the rear connecting frame contacts the right side of the rear limiting block, limiting the position of the connecting frame and aligning the welding edges of the two photovoltaic crystalline silicon plates to be welded at the positioning seam position. This can automatically position and guide the two photovoltaic crystalline silicon plates to be welded during welding, increasing the convenience and accuracy of positioning and preventing damage to the photovoltaic crystalline silicon plates.
[0008] Further, the left side of the front limiting block is aligned with the positioning seam, and the right side of the rear limiting block is aligned with the positioning seam;
[0009] Through the above technical solution, the positions of the right side of the front connecting frame and the left side of the rear connecting frame are limited, and the positions of the photovoltaic crystalline silicon plates to be welded are moved to the positioning seam position and stopped, increasing the positioning accuracy.
[0010] Further, the front moving frame moves left and right on the left side of the positioning seam, and the rear moving frame moves left and right on the right side of the positioning seam;
[0011] Through the above technical solution, the two photovoltaic crystalline silicon plates are driven to move, and the left photovoltaic crystalline silicon plate and the right photovoltaic crystalline silicon plate move towards each other, aligning the positions to be welded.
[0012] Further, guide rods are fixedly connected to the front and rear bottoms of the fixed frame, and the outer ends of the moving frames are respectively slidably connected to the outside of the corresponding guide rods;
[0013] Through the above technical solution, when the moving frame moves left and right, the guiding property and connection performance are increased, making its movement more stable.
[0014] Further, guiding pulleys are arranged at the bottoms of the connecting frames, and guiding chutes are arranged at the front and rear sides of the upper end of the fixed frame, and the guiding pulleys respectively slide inside the corresponding guiding chutes;
[0015] Through the above technical solution, when the connecting frame moves left and right, the guiding pulleys slide inside the guiding chutes, increasing the guiding property and stability of the connecting frame during movement, and simultaneously supporting the connecting frame.
[0016] Further, empty slots are arranged on the front and rear sides of the fixed frame;
[0017] Through the above technical solution, the collision impact caused when the connecting frame moves left and right is avoided.
[0018] Furthermore, the front and rear ends of the left and right sides of the bottom of the fixing frame are fixedly connected with rotating connecting seats, and the left and right ends of the threaded rod are respectively rotatably connected to the inner sides of the corresponding rotating connecting seats;
[0019] Through the above technical solution, the rotation stability of the threaded rod is increased, and the connection performance after installation on the fixing frame is increased.
[0020] The utility model has the following beneficial effects:
[0021] 1. In the utility model, first, two photovoltaic crystalline silicon plates to be welded are respectively placed on the upper part of the support frame for fixation, and the welding edges are aligned with the edges of the connecting frame. Then, the motor drives the threaded rod to rotate, driving the front moving frame to move to the right and the rear moving frame to move to the left. When the moving frame moves to the bottom of the mounting frame, the right end of the front connecting frame contacts the left side of the front limiting block, and the left end of the rear connecting frame contacts the right side of the rear limiting block, limiting the position of the connecting frame, so that the welding edge positions of the two photovoltaic crystalline silicon plates to be welded are aligned at the positioning seam. It can automatically position and guide the two photovoltaic crystalline silicon plates to be welded during welding, making the positions to be welded at their edges automatically aligned, increasing the efficiency of welding the photovoltaic crystalline silicon plates, and being able to move automatically, increasing the convenience and accuracy of positioning. It prevents the photovoltaic crystalline silicon plates from moving during wire welding, resulting in misalignment of the welding positions and damaging the photovoltaic crystalline silicon plates. At the same time, it avoids damaging the photovoltaic crystalline silicon plates during the manual alignment process.
[0022] 2. In the utility model, the motor drives the threaded rod to rotate, causing the moving frame, the connecting frame, and the support frame to move left and right. At the same time, the moving frame slides on the guide rod, and the guide pulleys arranged at the bottom of the connecting frame slide inside the guide chute, which is convenient for control and increases the moving precision. Moreover, the stability and guiding performance during the moving process are improved, increasing the ability of automatic control and increasing the efficiency during use.
