Description

Technical Field

[0001] This invention belongs to the field of crystal ring cutting technology, specifically, it relates to a crystal protection device and a crystal ring cutting equipment. Background Technology

[0002] Before industrial applications, the outer edge of silicon carbide crystals needs to be removed due to their irregular shape. Currently, crystal circumferential cutting involves first bonding the crystal to a resin plate, then fixing the resin plate to a rotating disk. The rotating disk is driven by a motor, and circumferential cutting is performed in conjunction with the cutting line feed.

[0003] In existing crystal circumferential cutting equipment, the outer circle of the resin plate and the edge of the crystal are prone to detaching during cutting. This detachment peels off the attached crystal portion, causing damage to the crystal surface. Therefore, to solve this problem, current methods often require manual application of adhesive three times to fix the circumferential cutting area and prevent detachment of the resin plate and crystal edge. Each adhesive application and fixing process takes about half an hour, indirectly affecting the crystal cutting efficiency.

[0004] Therefore, the technical problem to be solved by this application is: how to speed up the fixing of the outer circle / crystal edge skin of the resin plate. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a crystal protection device and a crystal ring cutting equipment. The technical effect of this application is to improve the fixing efficiency of the outer circle / edge skin of the resin plate.

[0006] The objective of this invention can be achieved through the following technical solution: a crystal protection device, comprising a mounting plate and a clamping mechanism, wherein there are at least two clamping mechanisms, which are circumferentially distributed on the mounting plate and connected thereto, to jointly clamp the outer circle of a component to be clamped; wherein the clamping mechanism is provided with a clamping station, and the clamping station can be dynamically adjusted relative to the movement of the component to be clamped.

[0007] In the aforementioned crystal protection device, the clamping mechanism includes: a fixed base, which is disposed on and connected to the mounting plate or is integral with it; a movable component, which is movably disposed on the fixed base and can adjust the distance between it and the fixed base; wherein, the fixed base and the movable component are respectively provided with at least one clamping unit, and the clamping unit can rotate at the clamping station as the object to be clamped rotates.

[0008] In the crystal protection device described above, the clamping unit has at least one rotation direction, which is substantially perpendicular to the movement direction of the movable part.

[0009] In the crystal protection device described above, the clamping unit is a ball bearing or a universal ball.

[0010] In the crystal protection device described above, the fixed base is provided with at least two mounting positions, and the movable part can be installed on different mounting positions to adjust the clamping size.

[0011] In the aforementioned crystal protection device, the movable component includes: a mounting shaft, which is disposed on a fixed base; an elastic element / fastener, one end of which is connected to the fixed base and the other end of which is connected to the mounting shaft; and a first clamping arm, which is disposed on the mounting shaft, and the clamping unit is disposed on the side of the first clamping arm near the fixed base.

[0012] In the aforementioned crystal protection device, the movable component includes: an electric telescopic rod, which is mounted on a fixed base; a second clamping arm, which is mounted on the electric telescopic rod, and the clamping unit is mounted on the second clamping arm on the side near the fixed base.

[0013] In the crystal protection device described above, the first clamping arm is hinged to the mounting shaft, and the fixed base is provided with a limiting member, which can limit the swing of the first clamping arm.

[0014] In the crystal protection device described above, the mounting plate is provided with a clearance hole, which is used for the drive shaft of the crystal circumferential cutting equipment to pass through.

[0015] Another object of the present invention is to provide a crystal ring cutting device, comprising: a crystal protection device as described above, and further comprising: a support base connected to a mounting plate, wherein a rotating disk is provided on the support base, and the rotating disk is located between the clamping mechanism and the mounting plate.

[0016] The crystal circumferential cutting equipment described above also includes a sliding tailstock, which is positioned opposite to the support base and is used to move towards the clamping mechanism to press the crystal firmly against it. By incorporating the sliding tailstock, the crystal can be pressed down during circumferential cutting, preventing it from wobbling and ensuring cutting accuracy.

[0017] Compared with the prior art, the crystal protection device of the present invention can fix the outer circle of the resin plate / crystal edge skin during circumferential cutting, eliminating the manual glue application process and thus improving the fixing efficiency. Furthermore, by setting a dynamically adjustable clamping position, it can rotate with the rotation of the part to be clamped, fixing the edge skin without affecting the operation of the circumferential cutting equipment. In addition, by setting the first clamping arm and the mounting shaft as hinged, the first clamping arm can be rotated to facilitate the placement of the crystal into the clamping mechanism. After the first clamping arm moves to clamp, its swing is restricted by the limiting member to ensure clamping stability. The crystal circumferential cutting equipment of the present invention also improves the stability during circumferential cutting by setting a sliding tailstock to facilitate the movement and clamping of the crystal.

[0031] Example 1

[0032] The crystal protection device of this embodiment includes a mounting plate 100 and a clamping mechanism 200, as shown in the accompanying drawings. Figure 2The mounting plate 100 is used to mount multiple clamping mechanisms 200, which are circumferentially distributed on and connected to the mounting plate 100 to jointly clamp the outer circle of a component to be clamped. In practice, at least two clamping mechanisms are generally required to clamp the outer circle of the component. In special cases, embodiments using only one clamping mechanism in conjunction with other structures to clamp the component are not excluded. For example, in this embodiment, the clamping mechanism 200 is configured with three clamping mechanisms 200, which are equidistantly arranged to better clamp and fix the outer circle of the component to be clamped.

[0033] It is understood that the clamping mechanism 200 extends and retracts along the thickness direction of the workpiece to be clamped, and the clamping mechanism 200 is provided with a clamping station 230 on the extension and retraction path, which can be dynamically adjusted relative to the movement of the workpiece to be clamped.

[0034] It should be specifically noted that the movement of the workpiece to be clamped is based on the drive of the circumferential cutting equipment, not driven by the clamping component. This can be interpreted as the workpiece to be clamped moving on the clamping station 230, and the clamping station 230 can be dynamically adjusted relative to the movement of the workpiece to avoid interference with the drive components of the circumferential cutting equipment. In this embodiment, the movement of the workpiece to be clamped specifically refers to rotation. Of course, in other possible embodiments, the workpiece to be clamped may also move in a sliding, swinging, or other form, provided that the circumferential cutting condition is met.

[0035] The clamping mechanism 200 specifically includes a fixed base 210 and a movable part 220, as shown in the attached drawings of the instruction manual. Figure 3 The fixed base 210 is mounted on the mounting plate 100 and connected to it or is an integral part thereof; the movable part 220 is movably mounted on the fixed base 210 and the distance between it and the fixed base 210 can be adjusted.

[0036] It should be noted that at least one clamping unit 201 is provided on both the fixed base 210 and the movable part 220. The clamping unit 201 can rotate on the clamping station 230 as the workpiece to be clamped rotates. The clamping unit 201 has at least one direction of rotation, which is substantially perpendicular to the direction of movement of the movable part 220.

[0037] For example, the clamping unit 201 can be a ball bearing or a universal ball. In this embodiment, a universal ball is used. The distance between the universal ball on the fixed seat 210 and the universal ball on the movable part 220 can be adjusted as the movable part 220 moves. Under the pressure of the two universal balls, the thickness direction of the clamped part is fixed, but it can still rotate radially.

[0038] It is understood that the mounting base 210 has at least two mounting positions 211, and the movable part 220 can be installed on different mounting positions 211 to adjust the clamping size. For example, the crystal protection device of this embodiment can be adapted to 6-inch and 8-inch crystals.

[0039] The movable component 220 includes: a mounting shaft 221, an elastic element 222 / fastener, and a clamping arm, as shown in the attached diagram of the instruction manual. Figure 4 . Figure 4 As shown, the mounting shaft 221 is mounted on the fixed base 210; the elastic element 222 / fastener has one end connected to the fixed base 210 and the other end connected to the mounting shaft 221; the first clamping arm 223 is mounted on the mounting shaft 221, and the clamping unit 201 is mounted on the first clamping arm 223 on the side near the fixed base 210.

[0040] In some other embodiments, the movable element 220 includes: an electrically telescopic rod 224 and a second clamping arm 225, as shown in the accompanying drawings. Figure 5 The electric telescopic rod 224 is mounted on the fixed base 210 and can be driven to extend and retract via an electric mechanism, which is a conventional method in existing technology and will not be described in detail here. Additionally, the second clamping arm 225 is mounted on the electric telescopic rod 224, and the clamping unit 201 is mounted on the second clamping arm 225 on the side near the fixed base 210. It can be understood that the extension and retraction of the electric telescopic rod 224 can drive the extension and retraction of the second clamping arm 225, thereby adjusting the distance between the movable part 220 and the fixed base 210.

[0041] Understandably, the mounting shaft 221 is movable, and the extension or retraction of the clamping arm is controlled by the tension of the spring / rotation of the fastener thread, thereby adjusting the distance between the movable part 220 and the fixed seat 210.

[0042] It is understood that the first clamping arm 223 is hinged to the mounting shaft 221 to facilitate the placement of the crystal into the clamping mechanism 200. Furthermore, the fixing base 210 is provided with a limiting member 212, which restricts the swinging of the first clamping arm 223. After the crystal is clamped and fixed, the limiting member 212 prevents the first clamping arm 223 from swinging, ensuring stability during circumferential cutting.

[0043] Understandably, the mounting plate 100 is also provided with a clearance hole 110, which is used for the drive shaft of the crystal circumferential cutting equipment to pass through.

[0044] Example 2

[0045] This embodiment provides a crystal ring cutting device, including the crystal protection device of Embodiment 1, and further including a support base 300 and a sliding tailstock 500, as shown in the accompanying drawings. Figure 6The support base 300 is connected to the mounting plate 100, and the support base 300 is provided with a rotating disk 400, which is located between the clamping mechanism 200 and the mounting plate 100.

[0046] Understandably, the rotating disk 400 can be driven to rotate by a motor mounted on the support base. The motor shaft can pass through the clearance hole on the mounting plate 100 and connect to the rotating disk 400. Because the silicon carbide crystal is relatively thin, the clamping mechanism 200 cannot easily clamp it directly. A resin plate must first be mounted on the rotating disk 400, and then the crystal is bonded to the resin plate. During circumferential cutting, the cutting line set on the outside of the clamping mechanism 200 is used for feeding, which, in conjunction with the rotation of the rotating disk 400, simultaneously removes the outer circle of the resin plate and the edge of the crystal.

[0047] Understandably, the sliding tailstock 500 and the support base 300 are arranged opposite each other to move towards the clamping mechanism 200 to press the crystal firmly, preventing it from wobbling and ensuring cutting accuracy. For example, the sliding tailstock 500 can be fed by a horizontal moving mechanism, which can be an electric cylinder or a pneumatic cylinder.

[0048] The working principle of this embodiment is as follows: First, the crystal is bonded to the resin plate. Then, the first clamping arm 223 of each clamping mechanism 200 is rotated to place the resin plate between the multiple clamping mechanisms 200, and then the resin plate is fixed on the rotating disk 400. The first clamping arm 223 is reset so that it rests on the limiting member 212. Then, the mounting shaft 221 is adjusted so that the first clamping arm 223 clamps the outer circle of the resin plate, driving the sliding tailstock 500 to slide towards the resin plate to press against the crystal, and the circumferential cutting process can begin. Next, the cutting line set on the outside of the circumferential cutting equipment is fed so that the cutting line cuts into the area to be cut on the resin plate and the crystal. At this time, the motor set on the support base 300 is started, and the motor drives the rotating disk 400 to rotate. The rotation of the rotating disk 400 drives the resin plate to rotate, realizing the circumferential cutting. After the circumferential cutting is completed, the cut resin plate is removed. During the circumferential cutting process, the clamping unit 201 of the clamping mechanism 200 can rotate with the rotation of the resin plate / crystal, without interfering with the circumferential cutting.

[0049] The beneficial effects of this embodiment are: compared to existing circumferential cutting equipment, as shown in the accompanying drawings of the specification... Figure 1 As shown, this embodiment adds a crystal protection device to improve the fixing efficiency of the crystal edge skin; and adds a sliding tailstock 500 to slide and tighten the crystal, which also improves the stability during circumferential cutting.

[0050] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
