Description

Technical Field

[0001] The utility model relates to the technical field of single crystal round rod processing, in particular to an edge skin collecting device for a single crystal round rod. Background Art

[0002] Single crystal silicon usually refers to a material formed by silicon atoms in a certain arrangement. Silicon is the most common and widely used semiconductor material. When molten silicon solidifies, silicon atoms are arranged in a diamond lattice to form a crystal nucleus, which grows into grains with the same crystal plane orientation to form single crystal silicon. When single crystal silicon is processed in the form of a single crystal round rod, the edge skin will fall off from the surface, and the operator needs to collect the edge skin.

[0003] For example, a crystal rod edge skin collection device with the authorization announcement number "CN219971079U" can not only realize the automatic collection of crystal rod edge skin, but also can realize the transportation of a large number of crystal rods during transportation, effectively improve the transportation efficiency, and effectively avoid safety accidents. However, when the crystal rod edge skin collection device pushes the edge skin on the conveyor belt, because there is no obstruction on both sides of the scraper, the edge skin will slide out from both sides of the scraper, resulting in less edge skin collected by the scraper at one time, which reduces the working efficiency of the edge skin collection device. At the same time, after the crystal rod edge skin collection device moves the box to a suitable position next to the conveyor belt, there is no equipment to fix the box, which causes the box of the edge skin recovery device to move away from the conveyor belt during operation, which causes the edge skin to fall directly from the conveyor belt to the ground, which reduces the working quality of the edge skin recovery device. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that since there is no obstruction on both sides of the scraper, the edge skin will slide out from the two sides of the scraper, resulting in less edge skin collected by the scraper at one time, which reduces the working efficiency of the edge skin collecting device and there is no equipment to fix the box after the box is moved to a suitable position next to the conveyor belt, which causes the box to move away from the conveyor belt when the edge skin recovery device is working, which causes the edge skin to fall directly from the conveyor belt to the ground, thus reducing the working quality of the edge skin recovery device. A edge skin collection device for a single wafer rod is proposed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for collecting the edge skin of a single crystal rod is designed, comprising a box body, a box body supporting mechanism is provided on the outside of the box body, an outer wall of the box body is fixedly connected to a first horizontal plate, an outer wall of the first horizontal plate is fixedly connected to the bottom end of an electric telescopic rod, an end of the electric telescopic rod is fixedly connected to a bent rod, an edge skin pushing mechanism is provided on the surface of the bent rod, a plurality of collection boxes are placed inside the box body, the plurality of collection boxes are fitted together, and a collection port is processed on the outer wall of the box body.

[0007] Preferably, the box supporting mechanism includes a motor, the outer wall of the motor is fixedly connected to the box through a bracket, the output shaft of the motor is fixedly connected to a stud, the outer wall of the stud is threadedly connected to two nuts, the outer walls of the two nuts are movably connected to two connecting rods through pins respectively, the outer walls of the connecting rods are rotatably connected to the roller through pins, the middle part of one connecting rod is movably connected to the middle part of the other connecting rod through a pin, the outer walls of the two connecting rods are movably connected to a moving block through a pin, and the outer wall of the moving block is slidably connected to the square plate through a slide groove.

[0008] Preferably, the outer walls of the two rollers are both in contact with the box body, the outer wall of the square plate is in contact with the shell body, and the outer wall of the shell body is fixedly connected to the box body.

[0009] Preferably, the side skin pushing mechanism includes a second cross plate and a first baffle plate, the outer wall of the second cross plate is fixedly connected to the bent rod, the outer wall of the second cross plate is slidably connected to the slider via a slide groove, the outer wall of the second cross plate is slidably connected to the first baffle plate via a through hole, the outer wall of the first baffle plate is fixedly connected to the limit plate, the outer wall of the first baffle plate is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to the second cross plate, the outer wall of the second cross plate is slidably connected to the second baffle plate via a slide groove, and the outer wall of the slider is fixedly connected to the handle.

[0010] Preferably, the outer wall of the box is fixedly connected to a plurality of columns, and universal wheels are installed at the lower ends of the outer walls of the plurality of columns.

[0011] Preferably, the outer walls of the two nuts are slidably connected to the box body through a slide groove and a bracket, and both ends of the stud are rotatably connected to the box body through a bearing and a bracket.

[0012] The utility model proposes a device for collecting the edge skin of a single wafer rod, which has the beneficial effects that: through the cooperation of a bending rod and an edge skin pushing mechanism, after the first baffle moves to a suitable position, the slider drives the limit plate to move, and after the limit plate is stuck by the slider, the operator stops moving the slider, and the bending rod drives the edge skin pushing mechanism to move. When the second baffle blocks the edge skin, after the slider moves away from the limit plate, the spring drives the first baffle to reset, and the electric telescopic rod contracts to drive the second horizontal plate to move. The second horizontal plate, the first baffle and the second baffle drive the edge skin to move at the same time to prevent the edge skin from slipping out. After the first baffle and the second baffle are pressed against the box body, the first baffle and the second baffle begin to slide on the second horizontal plate, and the edge skin falls into the collection box through the collecting port. The above method can prevent the edge skin from slipping out during movement, which improves the working efficiency of the edge skin collecting device.

[0013] Through the cooperation of the box and the box support mechanism, the motor drives the stud to rotate, the stud drives the nut to move, the nut drives the connecting rod to move, the connecting rod drives the roller to roll on the box, and at the same time, the other end of the connecting rod drives the moving block to move, and the moving block drives the square plate to move. In this way, the square plate contacts the ground and the universal wheel leaves the ground. This avoids the movement of the box, which improves the working quality of the edge skin collection device. BRIEF DESCRIPTION OF THE DRAWINGS
