Description

Technical Field

[0001] The utility model relates to the technical field of installation of raw materials such as silicon rods, and in particular to a cutting tool. Background Art

[0002] When producing integrated circuit related products, the raw materials (such as silicon) need to be cut according to the requirements. Before cutting the raw materials using cutting equipment, the raw materials such as silicon rods need to be placed on the tooling and the raw materials such as silicon rods need to be placed stably.

[0003] At present, the tooling is generally set as a trimmed steel plate and is set on the cutting equipment. In order to ensure that raw materials such as silicon rods are stably and placed directly on the tooling, generally, by applying glue, bakelite is set at the end of raw materials such as silicon rods, and then glue is applied on the bakelite to make the bakelite stably installed on the tooling. When installing raw materials such as silicon rods on the tooling with bakelite and glue, in order to accurately find the center and baseline of raw materials such as silicon rods and place them directly on the tooling, it is necessary to use a square ruler and auxiliary marble to achieve the accuracy of raw materials such as silicon rods. Only after accurate locating can bakelite be used to stably install raw materials such as silicon rods on the tooling.

[0004] Because it takes a long time for the glue to completely solidify, after completing the above steps, it is necessary to cool the tooling and raw materials such as silicon rods. From the actual production situation, it can be seen that the cooling time takes at least four hours, that is, after the raw materials such as silicon rods are adhered and installed on the tooling, it is necessary to wait for four hours before cutting on the machine. In this way, the factory for batch production needs to prepare multiple tooling and bakelite at the same time, because the staff first needs to adhere multiple silicon rods and other raw materials one by one on multiple tooling and perform cold screening, otherwise it will not meet the high-efficiency production at all, but the corresponding increase in factory production costs. In addition, even if multiple tooling and bakelite are prepared, it is easy to need to wait, because it takes at least four hours to cool, and the installation of raw materials such as silicon rods is relatively fast. Therefore, it is very likely that after all the raw materials such as silicon rods to be cut are installed on the tooling, the glue of the silicon rods and tooling installed first is still completely unsolidified, affecting production efficiency.

DETAILED DESCRIPTION

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0028] As described in the background technology, before cutting the silicon rod, etc., it needs to be left to air for at least four hours after being attached to the tooling, and multiple toolings are required, which increases production costs and affects production efficiency. In order to solve this problem, this embodiment provides another technical tooling solution.

[0029] Example 1

[0030] like Figure 1 , Figure 3 , Fig.10 As shown, specifically, the tooling includes a base 1, an annular plate 3, a rotating plate 4 and a clamping plate 2. The annular plate 3 is adjustable and arranged on the base 1. The rotating plate 4 is installed on the annular plate 3 and can rotate around the central axis of the annular plate 3. A plurality of clamping plates 2 are evenly distributed on the outside of the annular plate 3, and a snap plate 21 is arranged near one end of the annular plate 3. The end of the snap plate 21 extends into the annular plate 3. At the same time, the snap plate 21 and the rotating plate 4 are meshed and connected. Therefore, when the rotating plate 4 is rotated, the snap plate 21 can be controlled to drive the clamping plate 2 to move, thereby adjusting the position of the clamping plate 2. When the tooling is installed on the silicon rod, the rotating plate 4 is rotated according to the size of the silicon rod to adjust the position of the clamping plate 2, and the end of the silicon rod is extended between the plurality of clamping plates 2. Then, the rotating plate 4 is rotated in the opposite direction, so that the plurality of clamping plates 2 can be gathered together, and the end of the silicon rod is clamped, so that the silicon rod is stably arranged on the side of the annular plate 3. In order to reduce the probability of the clamping plate 2 damaging the silicon rod, a rubber layer may be provided on the side wall of the clamping plate 2 adjacent to the silicon rod, so that the silicon rod can be protected by the rubber layer.

[0031] like Figure 3 , Figure 4As shown in the figure, in order to achieve the self-rotation installation of the rotating plate 4, a groove 31 is provided on the side surface of the annular plate 3. The thickness of the rotating plate 4 is equal to the depth of the groove 31, and the diameter is smaller than the diameter of the groove 31. The rotating plate 4 is arranged in the groove 31, and a central shaft 41 is arranged in the middle of the rotating plate 4. At the same time, the central shaft 41 penetrates through the annular plate 3. When it is necessary to rotate the rotating plate 4, the staff holds the end of the central shaft 41 protruding from the annular plate 3 and twists the central shaft 41 to rotate, thereby controlling the rotation of the rotating plate 4 and providing support for controlling the relative movement of multiple clamping plates 2.

[0032] As Figure 5 , Figure 7 shown in the figure, in order to stably install the clamping plate 2 on the annular plate 3, a plurality of buckle grooves 33 are provided on the side of the annular plate 3 away from the groove 31. Each buckle groove 33 is arranged along the radial direction of the annular plate 3, and the plurality of buckle grooves 33 are evenly distributed along the circumferential direction of the annular plate 3. The end faces of the buckle groove 33 and the buckle plate 21 are the same, and are both set as concave-convex structures. For example, they can be set as a structure similar to the Chinese character '中'. With the cooperation of the buckle groove 33 and the buckle plate 21, the clamping plate 2 can be stably and movably arranged on the side of the annular plate 3, facilitating the relative movement of the clamping plate 2 relative to the annular plate 3 under the action of the rotating plate 4. In addition, the end of the clamping plate 2 protrudes from the annular plate 3, facilitating the clamping of the silicon rod by the clamping plate 2.

[0033] As Figure 6 , Figure 7 shown in the figure, in order to control the movement of the buckle plate 21 by rotating the rotating plate 4, a spiral groove 42 is provided on the side wall of the rotating plate 4. At the same time, a spiral tooth is provided on the buckle plate 21, and the spiral tooth is matched with the spiral groove 42. However, the end of the bolt press is flush with the side wall of the buckle plate 21. Therefore, when the bolt tooth and the spiral groove 42 are engaged, the movement of the buckle plate 21 can be controlled under the action of the rotating plate 4 to adjust the position of the clamping plate 2.

[0034] As Figure 3 , Figure 7 shown in the figure, in order to automatically find the center of the silicon rod, at least three clamping plates 2 are provided, and the three clamping plates 2 are evenly distributed on the outside of the annular plate 3, so as to control the movement of the silicon rod and make it find the baseline during the movement of the clamping plate 2, facilitating the cutting of the silicon rod. In addition, a scale groove 22 can be provided on the side wall of the buckle plate 21. By reading the scale, the size of the silicon rod can be known. Specifically, the numbers displayed on the scale groove 22 can be set as the sum of the length of the buckle plate 21 protruding from the annular plate 3 and the radius of the annular plate 3, that is, the radius of the silicon rod. Therefore, the size of the silicon rod can be known by reading the scale groove 22, or it can be set only as the length of the buckle plate 21 protruding from the annular plate 3, etc. In short, it facilitates the measurement of the size of the silicon rod.

[0035] As Figure 5 , Figure 7As shown, in order to stably place the adjusted clamping plate 2 relative to the annular plate 3, a sliding hole 23 is provided on a certain snap plate 21. The sliding hole 23 is arranged along the length direction of the snap plate 21, and a threaded hole is provided at the end of the corresponding snap groove 33, and a limiting member 34 is threadedly inserted at the threaded hole. The limiting member 34 is arranged through the sliding hole 23 and can press the snap plate 21 so as to limit the movement of the snap plate 21 under the action of friction.

[0036] like Figure 2 , Figure 5 As shown, in order to achieve the adjustability of the annular plate 3, a support tube 12 is provided on the base 1, and a protruding plate is provided on the top of the side of the support tube 12. The protruding plate is threaded with an adjusting screw 11. In addition, a plug plate 32 is provided below the annular plate 3, and a protruding plate 35 is fixedly provided on the side of the plug plate 32. The plug plate 32 is inserted into the support tube 12, and the protruding plate 35 is connected and sleeved on the upper end of the adjusting screw 11 through a bearing. Therefore, when it is necessary to adjust the height of the annular plate 3 according to silicon rods of different sizes, the adjusting screw 11 can be rotated to force the plug plate 32 to move in the support tube 12, thereby achieving the height adjustment of the annular plate 3, which provides convenience for clamping silicon rods of different sizes.
