Description

Technical Field

[0001] The invention relates to the technical field of machine tools, and in particular to a silicon core external cylindrical grinding integrated machine. Background Art

[0002] Silicon core is a product used to grow native polysilicon. In the production process of polysilicon, it is used as a carrier to grow native polysilicon. Silicon core is mainly high-purity silicon, but its molecular arrangement structure is irregular, which is different from the regular arrangement of single crystal silicon. Silicon core is usually divided into electronic grade and solar grade, among which most of the domestic applications are solar grade silicon core. Solar grade silicon core is mainly used to manufacture solar photovoltaic panels. First, the silicon material is cast into ingots, sliced ​​or directly sliced ​​with single crystal silicon rods, and then a PN junction is formed by doping and diffusion on the silicon wafer. Then, the silver paste is printed on the silicon wafer by screen printing to make the grid line. After sintering, the back electrode is made at the same time, and an anti-reflection film is applied on the surface with the grid line. A series of processes such as a single solar cell are processed and finally assembled into a solar panel as needed.

[0003] The outer cylindrical surface of the silicon core needs to be polished during the processing. Currently, conventional polishing equipment needs to perform rough grinding first. After the rough grinding is completed, the machine tool is turned off and the grinding wheel is stopped. The rough grinding wheel is dressed with a grinding wheel dresser to remove impurities and wear layers on the surface. The rough grinding wheel is removed and the fine grinding wheel is installed in the same way to ensure that the fine grinding wheel has a finer particle size to obtain better surface quality. However, this polishing method is cumbersome to operate and affects the polishing efficiency. Therefore, we propose a silicon core outer cylindrical grinding all-in-one machine to solve this problem.

When the push plate 14 contacts the touch button 15, the control switching motor 711 is automatically started, and the switching motor 711 drives the driving gear 710 to rotate. The driving gear 710 drives the rotating frame 7 to rotate 90° through the meshing with the arc-shaped rack 709, so that the fine grinding wheel 701 moves to the front side and abuts against the silicon core. , achieving a more detailed grinding of the silicon core, at the same time, the coarse grinding wheel 713 abuts against the lower scraper 707, so that the grinding waste on the surface of the coarse grinding wheel 713 is scraped off by the lower scraper 707, so as to facilitate the next grinding work, while the mobile platform 601 continues to move forward, driving the linkage plate 10 to move synchronously, and the push plate 14 is blocked by the touch button 15 and stops moving forward. When the push plate 14 contacts the trigger button 12, the second servo motor 606 is controlled to run in the reverse direction, thereby driving the mounting frame 6 and the fine grinding wheel 701 to move backward, so that it can be automatically ended; During the grinding process, the abutment disk 24 is driven to rotate synchronously through the abutment between the silicon core and the abutment disk 24, and the abutment disk 24 drives multiple slides 28 to perform circular motion. The slides 28 move outward along the slide rails 27 under the action of centrifugal force, and drive the connecting ring 30 to rotate while moving to the right through the connecting rod 29. The connecting ring 30 drives the linkage ring 38 to move to the right and compresses the connecting spring 31. The pressure of the connecting spring 31 is monitored by the third pressure sensor 33. When the silicon core rotates smoothly and the pressure sensed by the third pressure sensor 33 is relatively stable, when the silicon core is unstable and shakes, the rotation speed of the abutment disk 24 is affected, so that the pressure sensed by the third pressure sensor 33 changes, and the controller 103 controls the rotating motor 304 and the driving motor 712 to stop running, thereby stopping the grinding work to avoid accidents.
