Description

Technical Field

[0001] This utility model relates to the field of square silicon processing technology, and in particular to a square silicon chamfering device. Background Technology

[0002] Square-core silicon is a silicon material workpiece with a square cross-section, commonly used in semiconductor, optoelectronics, or precision machinery fields. These workpieces require precision machining during manufacturing, such as chamfering and tapering, to meet the structural or functional requirements of specific application scenarios. Tapering refers to machining a conical structure at the end, such as a plug-in interface, to improve sealing, alignment accuracy, or optical performance. Chamfering refers to removing sharp edges to prevent stress concentration and cracks, while also avoiding scratching other components during assembly.

[0003] The existing square-core silicon grinding and chamfering processes are carried out using grinding machines and chamfering machines respectively. The two processes are carried out independently, which requires the workpiece to be clamped, positioned and transferred multiple times. This not only results in low production efficiency, but also requires two sets of independent equipment and operators, leading to high production and maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a square-core silicon chamfering device that can realize the integrated processing of chamfering and taper grinding of square-core silicon workpieces, improve production efficiency, reduce production and maintenance costs, and effectively solve the problems in the prior art.

[0005] This utility model provides a square silicon core chamfering device, including a grinding mill and a frame. A conveying device for transporting the square silicon core workpiece is provided on one side of the grinding mill, and a lifting device for lifting the square silicon core workpiece is provided at one end of the conveying device. A moving mechanism is mounted on the frame, and the moving mechanism includes a conveying rail. A first conveying section and a second conveying section are slidably arranged on the conveying rail. A chamfering mechanism is provided at the bottom of both the first and second conveying sections. The chamfering mechanism includes a chamfering component for chamfering the square silicon core workpiece. A clamping mechanism and a limiting mechanism for limiting the square silicon core workpiece are respectively provided on both sides of the chamfering component.

[0010] Preferably, an arc-shaped sleeve is fixedly connected inside the mounting cover, a mounting base is fixedly installed on the inner wall of the arc-shaped sleeve, and a grinding wheel is rotatably mounted on the mounting base.

[0011] Preferably, a motor is fixedly installed inside the mounting cover, and a transmission wheel is fixedly installed at both the output end of the motor and one end of the grinding wheel. A transmission belt is sleeved on the transmission wheel, and the transmission belt synchronously connects the grinding wheel and the output end of the motor.

[0015] The square-core silicon chamfering device provided in this embodiment of the invention has the following advantages compared to the prior art:

[0016] 1. This utility model sets up a first conveying section and a second conveying section, both of which are equipped with a chamfering mechanism. The first and second conveying sections drive the chamfering mechanism to move alternately. During the movement, the chamfering mechanism simultaneously chamfers the four corners of the square silicon workpiece. Then, the square silicon workpiece is conveyed to a grinding machine for grinding. This realizes the continuous operation of "feeding, chamfering, and grinding" of the square silicon workpiece, reduces the time wasted in the traditional multi-equipment turnaround, improves processing efficiency, and reduces the cost of purchasing and maintaining multiple equipment.

[0032] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Please refer to Figures 1-10 This utility model provides a square silicon chamfering device, including a grinding mill 1 and a frame 7. A conveying device 4 for conveying square silicon workpieces 6 is provided on one side of the grinding mill 1, and a lifting device 5 for lifting the square silicon workpieces 6 is provided at one end of the conveying device 4. A moving mechanism 3 is installed on the frame 7. The moving mechanism 3 includes a conveying rail 31. A first conveying part 32 and a second conveying part 33 are slidably arranged on the conveying rail 31. A chamfering mechanism 2 is provided at the bottom of both the first conveying part 32 and the second conveying part 33. The chamfering mechanism 2 includes a chamfering component 21 for chamfering the square silicon workpieces 6. A clamping mechanism 22 and a limiting mechanism 23 for limiting the square silicon workpieces 6 are respectively provided on both sides of the chamfering component 21.

[0034] Square silicon workpieces 6 are arranged equidistantly on the conveying device 4. The conveying device 4 is started to transport the square silicon workpieces 6 horizontally to the lifting device 5. When the square silicon workpieces 6 reach the designated position, the photoelectric sensor triggers the lifting device 5 to start. The lifting device 5 is hydraulically driven to vertically lift the square silicon workpieces 6 to a preset height aligned with the chamfering mechanism 2, ensuring that the edges of the square silicon workpieces 6 are precisely matched with the processing trajectory of the grinding wheel 216.

[0035] One end of the conveyor rail 31 is fixedly installed on the top of the frame 7, and the other end is fixedly installed on the side of the grinding machine tool 1. The lower surfaces of the first conveyor section 32 and the second conveyor section 33 are both fixedly connected to the mounting box 34. Two clamping cylinders 24 are fixedly installed in the mounting box 34 to drive the chamfering component 21 and the clamping mechanism 22 respectively.

[0036] The first conveying part 32 and the second conveying part 33 are located at both ends of the conveying rail 31, respectively. The first conveying part 32 and the second conveying part 33 slide along the conveying rail 31 and work alternately. When the first conveying part 32 clamps the square silicon workpiece 6, the second conveying part 33 moves towards the first conveying part 32 to chamfer one end of the square silicon workpiece 6. Then the second conveying part 33 resets and clamps the square silicon workpiece 6. The first conveying part 32 moves towards the second conveying part 33 to chamfer the remaining part of the square silicon workpiece 6. After the chamfering is completed, one end of the square silicon workpiece 6 is conveyed into the grinding machine tool 1 for grinding the end of the square silicon workpiece 6.

[0037] The first conveying unit 32 and the second conveying unit 33 operate alternately to form a continuous processing cycle, thereby realizing the integrated processing of the square silicon workpiece 6, reducing the time wasted in the traditional multi-equipment turnaround and improving processing efficiency.

[0038] The chamfering assembly 21 includes a protective box 211, the upper end of which is fixedly connected to the mounting box 34, and the bottom of the protective box 211 is provided with a pull-out bottom plate 212.

[0039] The protective box 211 encloses the working area of ​​the grinding wheel 216, effectively preventing debris from flying out. The pull-out bottom plate 212 is designed with a sliding rail structure, which can be quickly pulled out to clean up grinding debris.

[0040] The chamfering assembly 21 also includes a symmetrically arranged first clamping arm 213, which is located inside the protective box 211. The upper end of the first clamping arm 213 is fixedly connected to the gripper of the clamping cylinder 24 above it. The lower end of the first clamping arm 213 is fixedly connected to a mounting cover 214. An arc-shaped sleeve 215 is fixedly connected inside the mounting cover 214. A mounting base 217 is fixedly installed on the inner wall of the arc-shaped sleeve 215. A grinding wheel 216 is rotatably mounted on the mounting base 217. A motor 219 is fixedly installed inside the mounting cover 214. A transmission wheel 218 is fixedly installed on both the output end of the motor 219 and one end of the grinding wheel 216. A transmission belt 210 is sleeved on the transmission wheel 218. The transmission belt 210 synchronously connects the grinding wheel 216 and the output end of the motor 219.

[0041] The grinding wheel 216 is made of diamond. The motor 219 drives the transmission wheel 218 to rotate the grinding wheel 216 at high speed through the transmission belt 210. The grinding wheel 216 contacts the edges of the square silicon workpiece 6. The chamfering assembly 21 moves through the first conveying part 32 and the second conveying part 33, gradually grinding the edges to form a chamfer 61. When the arc-shaped sleeves 215 on both sides are in contact, the grinding wheels 216 on them are circumferentially distributed, which can process the four edges of the square silicon workpiece 6 at the same time, shortening the processing time.

[0042] The clamping mechanism 22 includes a second clamping arm 221 arranged symmetrically. The upper end of the second clamping arm 221 is fixedly connected to the jaw of the clamping cylinder 24 above it. A plurality of limiting wheels 222 are rotatably installed on the lower end of the second clamping arm 221. The limiting wheels 222 clamp the square silicon workpiece 6. The limiting mechanism 23 includes a fixed seat 231. The fixed seat 231 is fixedly installed on the lower surface of the mounting box 34. A limiting sleeve 232 is fixedly installed on the fixed seat 231. The limiting sleeve 232 is sleeved on the outside of the square silicon workpiece 6.

[0043] The second clamping arm 221 of the clamping mechanism 22 closes under the drive of the cylinder, and flexibly clamps both sides of the workpiece through the limiting wheel 222, ensuring the stability of the square silicon workpiece 6 while avoiding surface damage caused by rigid clamping. After the square silicon workpiece 6 is chamfered, one end is transported to the inside of the grinding machine tool 1 through the first conveying part 32. The square silicon workpiece 6 is fixed and rotated and ground by the fixture inside the grinding machine tool 1. At this time, the first clamping arm 213 and the second clamping arm 221 on the outside open, releasing the restriction on the square silicon workpiece 6. The limiting sleeve 232 sleeved on the outside of the square silicon workpiece 6 limits it and prevents its radial displacement.

[0044] The ends of the square-core silicon workpiece 6 are ground by a grinding machine 1 to form a conical part 62, and the edges are ground by a grinding wheel 216 to form a chamfered part 61.

[0045] During the transport process, the square silicon workpiece 6 is first chamfered by the chamfering mechanism 2 to form a chamfered part 61. Then it directly enters the grinding machine 1 to perform conical grinding on the end to form a conical part 62. The two processes are seamlessly connected by the transport part of the moving mechanism 3 without the need for secondary clamping. Through the collaborative design of the chamfering mechanism 2 and the grinding machine 1, the chamfering of the edges and the conical grinding of the end are completed in a single process, eliminating the time loss of traditional multi-process switching.

[0046] In summary, the working principle of the square-core silicon chamfering device of this utility model embodiment is as follows:

[0047] The square silicon workpiece 6 is automatically conveyed to the lifting device 5 via the conveying device 4. After being lifted to the processing height, the clamping mechanism 22 alternately clamps the square silicon workpiece 6. The first conveying part 32 and the second conveying part 33 work alternately to chamfer the square silicon workpiece 6 in sequence. Then, one end of the chamfered square silicon workpiece 6 is sent to the grinding machine 1. The grinding machine 1 grinds the end of the square silicon workpiece 6 to form a conical part 62, realizing the integrated processing of the square silicon workpiece 6, reducing the time wasted by the traditional multi-equipment turnaround, and improving processing efficiency.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
