Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, specifically to degumming equipment for the production of square silicon cores. Background Technology
[0002] The current method for preparing squaring silicon cores involves first drawing silicon rods with a diameter of 200–300 mm and a length of 1.5–4 m using the Czochralski method. One end of the rod is then bonded to a crystal substrate with a special adhesive. The substrate is then hung on a vertical cutting machine, and the rod is cut into squaring silicon cores of appropriate sizes (10×10 mm, 15×15 mm, or 18×18 mm). During the cutting process, fine steel wires coated with diamond microparticles are used to move back and forth or unidirectionally at high speed on the workpiece. The silicon rod is cut through the square wire mesh formed by the intersection of diamond wires on the machine tool to obtain a slender squaring silicon core.
[0003] After the silicon core is cut by the vertical cutting machine, it is necessary to separate the cut silicon core from the crystal seat because the silicon core and the crystal seat are fixed with adhesive. The method of debonding is to pour hot water at about 70°C onto the connection between the silicon rod and the crystal seat.
[0004] However, existing debinding equipment used in silicon core production has the following shortcomings: The traditional method involves manually pouring hot water onto the bonding area between the crystal substrate and the silicon core, which is time-consuming, labor-intensive, and wasteful of water. This solution proposes to design a debonding device that allows water to be recycled, filtered, and reused, and operates automatically. Utility Model Content

By setting up a debonding mechanism, rotating the first threaded rod, fixing the square silicon core with the fixing plate, controlling the controller to control the electric telescopic rod to move the first connecting plate, and pushing the locking block through the locking plate to move the square silicon core, the spring initially deforms significantly, and then the spring deforms slightly.

[0016] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments: like Figure 1 -Appendix Figure 8This utility model provides a degumming device for the production of square silicon cores, including a degumming box 1. A degumming mechanism 3 and a circulation mechanism 4 are installed inside the degumming box 1. The degumming mechanism 3 includes two support plates 31. A block 38 is arranged on the right side inside the degumming box 1. An electric telescopic rod 39 is arranged inside the block 38. A first connecting plate 310 is arranged at the output shaft of the electric telescopic rod 39. Limiting plates 314 are fixedly connected to the front and rear sides of the first connecting plate 310. A clamping plate 311 is arranged on the front and rear sides of the first connecting plate 310. A guide rod 312 is arranged on the left side of each clamping plate 311. A spring 313 is arranged on the outside of each guide rod 312. A plate 32 is arranged on the top of each support plate 31. A first threaded rod 33 is threaded through the inside of each plate 32. A fixed rod is arranged near the center of each first threaded rod 33. A fixed plate 34 is provided. Each support plate 31 is fixedly connected to a first slider 35 at the center away from the degumming box 1. A locking block 36 is fixedly connected to the bottom of each support plate 31. A controller 37 is provided on the front side of the degumming box 1. One side of each spring 313 is fixedly connected to the side end of the locking plate 311. The other side of each spring 313 is fixedly connected to the inside of the side end of the first connecting plate 310. The right side of each locking plate 311 is locked to the left side of the locking block 36. A water heater 2 is provided on the left side of the degumming box 1. A water outlet pipe 5 is provided at the bottom of the water heater 2. The water outlet pipe 5 is connected to the inside of the degumming box 1. A valve body 6 is provided at the connection between the water outlet pipe 5 and the degumming box 1. Two sets of support plates 7 are symmetrically arranged inside the degumming box 1. In use, the top of the multiple support plates 7 supports the crystal seat 8. A silicon core 9 that has been cut but still maintains the shape of a cylindrical silicon rod is bonded to one side of the crystal seat 8 by adhesive.
[0017] The overall effect of Embodiment 1 is as follows: the relevant components can improve the degumming efficiency of traditional degumming equipment for the production of square silicon cores through mechanical transmission. The function of setting multiple support plates 7 is to stably support the crystal seat 8 and the square silicon core 9. The function of setting the fixing plate 34 is to clamp and fix the square silicon core 9. The function of setting the spring 313 as a strong spring is to promote the separation of the crystal seat 8 and the square silicon core 9 and prevent the crystal seat 8 and the square silicon core 9 from being forcibly separated without the softening effect of hot water. This mechanical transmission method accelerates the progress of subsequent process steps.
[0018] Example 2, as Figures 1-8As shown, the circulation mechanism 4 includes a support frame 41, a filter screen 42 is provided inside the support frame 41, second sliders 44 are fixedly connected to the left and right sides of the support frame 41 respectively, a second connecting plate 43 is fixedly connected to the front side of the support frame 41, two second threaded rods 45 are symmetrically arranged on the front side of the second connecting plate 43, a box body 46 is provided on the left side of the degumming box 1, a pump 47 is provided inside the box body 46, a water pump pipe 48 is provided on one side of the pump 47, a water supply pipe 49 is provided on the other side of the pump 47, the right side of the water pump pipe 48 is connected to the inside of the degumming box 1, and the top of the water supply pipe 49 is connected to the water heater 2.
[0019] The effect achieved by the entire embodiment 2 is as follows: by setting up the circulation mechanism 4, the filter screen 42 and the support frame 41 are locked inside the degumming box 1 by the second threaded rod 45. The glue mixture filtered by the filter screen 42 is pumped by the pump 47 and transported to the water heater 2 through the water pipe 49, which facilitates the recycling of water resources.
[0020] The working principle of the entire equipment is as follows: Installation and inspection phase: Before starting the test, ensure that all parts of the structure are in a stable state to prevent any part of the structure from malfunctioning after the work is completed.
[0021] Stage of placing crystal base and square silicon core: Using hoisting equipment, place crystal base 8 and square silicon core 9 inside the degumming box 1. The hoisting equipment places the bottom of crystal base 8 on the outside of support plate 7 to fix its position. Then, the operator rotates the first threaded rod 33. The outside of the first threaded rod 33 rotates inside the plate 32. At the same time, the first threaded rod 33 drives the fixing plate 34 to clamp and fix the square silicon core 9.
[0022] Degumming Stage: The hot water inside water heater 2 is heated to 70℃. Valve 6 is opened, and hot water is released into the degumming chamber 1 through outlet pipe 5. When the hot water submerges the connection between crystal seat 8 and square silicon core 9, valve 6 is closed. Controller 37 controls the electric telescopic rod 39 to move back and forth. The extended end of the electric telescopic rod 39 drives the first connecting plate 310 to move to the right inside the degumming chamber 1. Since the adhesive at the connection between crystal seat 8 and square silicon core 9 is not softened, (the side of crystal seat 8 presses against the connection of crystal seat 8 to ensure that the square silicon core and the rotation axis of crystal seat 8 are concentric, facilitating stable degumming, such as...) Figure 8(Demonstration) When the first connecting plate 310 moves, it compresses the spring 313, causing the spring 313 to deform. The limiting plate 314 slides inside the degumming box 1. Then, the controller 37 controls the extended end of the electric telescopic rod 39 to move in the opposite direction, and the spring 313 gradually recovers its deformation. When the adhesive is softened by hot water, as the controller 37 controls the electric telescopic rod 39, the extended end of the electric telescopic rod 39 drives the locking block 36 to move to the right inside the degumming box 1 via the locking plate 311. The first slider 35 moves inside the degumming box 1, and the synchronous belt... When the moving silicon core 9 detaches from the connection point of the crystal base 8, the spring 313 undergoes a slight deformation. Then, the controller 37 controls the extended end of the electric telescopic rod 39 to move in the opposite direction. The movement trajectories of the above structures are reversed. As the controller 37 controls the electric telescopic rod 39 to repeatedly move back and forth, the adhesive of the silicon core 9 is continuously washed with hot water to remove the adhesive. After the degumming work is completed, the controller 37 controls the electric telescopic rod 39 to make the silicon core 9 finally separate from the crystal base 8. Then, the silicon core 9 and the crystal base 8 are removed from the inside of the degumming box 1 using hoisting equipment.
[0023] Circulation stage: After being filtered by the filter screen 42, the gelatinous substance remains on the surface of the filter screen 42. The pump 47 is started, and the pump delivers the water filtered by the filter screen 42 to the inside of the water heater 2 through the water pump pipe 48 and the water supply pipe 49. The positioning of the second connecting plate 43 is released by rotating the second threaded rod 45. Then the second slider 44 slides out inside the degumming box 1 to clean the gelatinous substance remaining on the surface of the filter screen 42.
[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
