Description

Technical Field

[0001] This invention relates to the field of monocrystalline silicon material processing equipment, specifically to an automatic wire cutting system and cutting method for silicon material with adhesive. Background Technology

[0002] Edge scrap refers to the waste material cut from the edges of monocrystalline silicon round rods. This material is considered high-quality in photovoltaic monocrystalline silicon production, with high silicon purity, suitable for use in crystal pulling. Larger wafers require grinding to remove the surface coating before subsequent raw material processing. Before processing the edge scrap, it needs to be acid-washed to remove impurities from the surface. It is then bonded with a specific adhesive to form a continuous, whole piece of edge scrap, which is then cut using diamond wire cutting equipment. The resulting edge scrap needs to be de-adhesiveized.

[0003] During the cutting of the edge material, the operator needs to place the edge material into the processing position of the cutting machine. The cutting machine uses an internal lifting mechanism to lower the diamond line, and the cutting operation is completed during the lowering process. After cutting, the operator takes out the edge material.

[0004] Because operators need to work inside the cutting machine, there are not only safety hazards, but also many steps required after the edge material is cut. Operators need to repeatedly pick up and put down the edge material. During the cutting process, in order to prevent the edge material from shifting, operators need to constantly observe the cutting status of the edge material. It is impossible to pick up and put down other edge materials to be cut or those that have been cut during the cutting process. The overall operation speed is slow, and the only solution is to increase the number of operators, which increases production costs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic wire cutting system and method for silicone material with adhesive. The automatic wire cutting system enables the positioning and automatic cutting of the edge material, and also enables the automatic loading and unloading of the edge material, avoiding the need for a large number of operators, improving the degree of automation, and increasing work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

An infrared laser is fixed to the front wall of the frame; the infrared laser emits a beam of light that illuminates the surface of the edge material supported above the support block.

[0010] Preferably, the buffer mechanism includes: a positioning frame, a support, a push plate, a buffer component, and a clamping cylinder; the positioning frame is fixed above the support; the surface of the positioning frame has one or more holes arranged therein; the two sides of the positioning frame are provided with notches parallel to and corresponding to the holes; a clamping cylinder is horizontally fixed at the bottom of the positioning frame; the telescopic end of the cylinder is fixed to the bottom of the push plate; one or more buffer components are movably provided on the body of the push plate; the buffer component moves from the edge of the notch to the inside of the notch at the corresponding notch to clamp the positioning edge material.

[0011] A cutting method based on an automated wire cutting system for silicone with adhesive;

[0012] Step 1: Push the bin containing the edge material into the enclosure position to position the bin; the six-axis industrial robot uses suction cup grippers to transfer the top layer of edge material in the bin to the support block of the positioning mechanism, with the edge material placed horizontally with its flat side facing up.

[0013] Step 2: Activate the infrared laser, tilt the infrared laser at a range of 30-45°, and set the laser beam length between 0.5m and 2m; the laser point should illuminate the flat surface of the edge material.

[0015] Step 4: The six-axis industrial robot picks up the edge material according to the position adjusted by the positioning mechanism and transfers it to the top of the loading platform, with the flat side of the edge material facing down; the suction on the feeding plate fixes the edge material to the feeding plate; the adhesive seam of the edge material and the gap between the feeding plate are on the same vertical plane.

[0016] Step 4: Control the first drive motor to feed the feeding plate on the discharge mechanism into the wire cutter. The diamond wire of the wire cutter moves down along the bonding seam of the edge material to cut; the cut diamond wire enters the gap between the feeding plates.

[0017] Step 5: After the cutting is completed, the diamond wire is reset first, and then the feeding mechanism is reset after the diamond wire is reset.

[0018] Step 6: The six-axis industrial robot uses a suction cup gripper to pick up the edge material from the loading platform and transfer it to the buffer mechanism. The edge material is placed on the surface of the positioning frame with its flat side facing down. During the time interval when the edge material is cut by the online cutting machine, the six-axis industrial robot puts the cut edge material from the buffer mechanism into the feed port of the washing machine.

[0020] Adhesive-coated scrap metal is transferred between several mechanisms by industrial robots. The coordinated positioning of these mechanisms enables automated cutting of the scrap metal. This replaces the original manual operation method, reduces the number of steps workers need to handle the scrap metal, and improves production efficiency and automation. Attached Figure Description

[0043] A cutting method based on an automated wire cutting system for silicone with adhesive;

[0044] Step 1: Push the material box 6 containing the edge material into the enclosure 14 position to position the material box 6. The material box 6 is equipped with wheels at the bottom for easy movement. However, while it is easy to move, the material box 6 needs to be stable and stationary when loading material to avoid large deviations in position, which would affect the six-axis industrial robot 2 in picking up the edge material. Therefore, after moving to the designated work station, the activity range of the material box 6 needs to be restricted by the enclosure 14.

[0045] The six-axis industrial robot 2 uses suction cup grippers 3 to transfer the top layer of edge material in the material box 6 to the support block 7.3 of the positioning mechanism 7, with the edge material placed horizontally with its flat side facing upwards;

[0046] Step 2: Activate infrared laser 7.1. The infrared laser 7.1 is tilted at a range of 30-45°, and the ray length of the infrared laser 7.1 ranges from 0.5m to 2m; the laser point illuminates the flat surface of the edge leather.

[0047] Step 3: Control the second drive motor 7.6 to adjust the position of the edge material by turning it forward and backward, so that the adhesive seam of the edge material coincides with the laser point;

[0048] Step 4: The six-axis industrial robot 2 picks up the edge material according to the position adjusted by the positioning mechanism 7 and transfers it to the upper part of the loading platform 5, with the flat side of the edge material facing down; the suction on the feeding plate 5.3 fixes the edge material on the feeding plate 5.3; the gap between the adhesive seam of the edge material and the feeding plate 5.3 is on the same vertical plane.

[0049] Step 4: Control the first drive motor 4.7 to feed the feeding plate 5.3 on the discharge mechanism into the wire cutter 1. The diamond wire 1.1 of the wire cutter 1 moves down along the bonding seam of the edge material to cut; the cut diamond wire 1.1 enters the gap between the feeding plates 5.3.

[0050] Step 5: After the cutting is completed, the diamond wire 1.1 is reset first, and then the feeding mechanism is reset after the diamond wire 1.1 is reset;

[0051] Step 6: The six-axis industrial robot 2 uses the suction cup gripper 3 to pick up the edge material from the loading platform 5 and transfer it to the buffer mechanism 8. The edge material is placed on the surface of the positioning frame 8.1 with its flat side facing down. Taking advantage of the time interval during the cutting process of the edge material by the online cutting machine 1, the six-axis industrial robot 2 places the cut edge material from the buffer mechanism 8 into the feed inlet of the washing machine. Based on this automatic online cutting system, the cutting method specific to this system can be used to cut the adhesive seams of the edge material, reducing the number of steps required by operators. Unless otherwise described, the fixing methods mentioned above all use welding or threaded fastening techniques commonly used by industry professionals.

[0052] The working principle is as follows:

[0053] The gap between the infrared laser 7.1 irradiation point and the feeding plate 5.3 on the feeding mechanism corresponds to the gap between the feeding plate 5.3 and the wire cutter 1. When the feeding mechanism enters the wire cutter 1, the gap between the feeding plates 5.3 is exactly at the cutting position of the diamond wire 1.1. The six-axis industrial robot 2 only needs to move according to the preset position. Then, by adjusting the position of the edge material by the positioning mechanism 7, the positional relationship of the wire cut can be satisfied, so that the equipment can complete the automatic wire cut and transfer the edge material at the same time.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

A cutting method based on the automatic wire cutting system for silicone with adhesive as described in claim 7, comprising the following steps: Step 1: Push the bin containing the edge material into the enclosure position to position the bin; the six-axis industrial robot uses suction cup grippers to transfer the top layer of edge material in the bin to the support block of the positioning mechanism, with the edge material placed horizontally with its flat side facing up. Step 2: Activate the infrared laser, tilt the infrared laser within a range of 30-45°, and ensure that the laser beam length (S) is within the range of ≥0.5m; the laser point illuminates the flat surface of the edge leather. Step 3: Adjust the position of the edge material by controlling the second drive motor to rotate forward and backward, so that the adhesive seam of the edge material coincides with the laser point; Step 4: The six-axis industrial robot picks up the edge material according to the position adjusted by the positioning mechanism and transfers it to the top of the loading platform, with the flat side of the edge material facing down; the suction on the feeding plate fixes the edge material to the feeding plate; the adhesive seam of the edge material and the gap between the feeding plate are on the same vertical plane. Step 5: Control the first drive motor to feed the feeding plate on the discharge mechanism into the wire cutter. The diamond wire of the wire cutter moves down along the bonding seam of the edge material to cut; the cut diamond wire enters the gap between the feeding plates. Step 6: After the cutting is completed, the diamond wire is reset first, and then the feeding mechanism is reset after the diamond wire is reset. Step 7: The six-axis industrial robot uses a suction cup gripper to pick up the edge material from the loading platform and transfer it to the buffer mechanism. The edge material is placed on the surface of the positioning frame with its flat side facing down. During the time interval when the edge material is cut by the online cutting machine, the six-axis industrial robot puts the cut edge material from the buffer mechanism into the feed port of the washing machine.
