Description

Technical Field

[0001] The utility model relates to the field of silicon rod cutting, in particular to a self-positioning silicon rod cutting knife table. Background Art

[0002] Silicon rods are raw materials that are used in large quantities in the semiconductor and photovoltaic related industries.

[0003] In order to facilitate transportation and further processing, a silicon rod with a diameter of 200-300 mm and a length of 1.5-4 m needs to be cut into appropriate sizes (10×10 mm or 15×15 mm square rods).

[0004] For processing silicon rods, cutting equipment is required. Existing cutting equipment is generally divided into vertical and horizontal types. When the existing horizontal cutting tool table cuts the silicon rod, one end of the silicon rod is clamped, and then the tool table cuts from the unclamped end. However, since the clamped end is blocked by the clamp, the cutting net cannot cut to the bottom, so that the uncut part of the clamped end of the silicon rod needs to be cut off after cutting, resulting in material waste. Utility Model Content

[0005] The purpose of the utility model is to provide a self-positioning silicon rod cutting tool table to solve the above-mentioned problems existing in the prior art.

[0006] Technical solution: A self-positioning silicon rod cutting tool table, comprising:

[0007] A base, and a cutting portion disposed on the base;

[0008] Two ends of the base are provided with positioning mechanisms, and the positioning mechanisms include:

[0009] A housing, arranged on the base;

[0010] A positioning cylinder is connected to the shell and is located outside the shell. A through groove in the shape of a truncated cone is formed in the positioning cylinder. The diameter of the through groove gradually decreases from the side close to the tool table to the side away from the tool table. A plurality of through holes extending into the shell are formed on the surface of the through groove in the positioning cylinder.

[0011] The positioning member comprises a positioning cylinder installed in the housing, a positioning plate arranged at the output end of the positioning cylinder, and a plurality of positioning rods installed on the positioning plate and adapted to the through holes.

[0012] The utility model positions the two ends of the silicon rod by designing a positioning cylinder. When the silicon rod enters the truncated cone-shaped through groove, it is affected by the through groove and gradually adjusts its position until both ends are positioned. After positioning, the positioning cylinder drives multiple positioning rods to press against the silicon rod. When the cutting net is cutting, the cutting net can cut to the end of the silicon rod through the gap between the positioning rods and the cutting line groove pre-opened on the positioning cylinder, thereby avoiding material waste caused by intercepting the uncut part of the end.

[0013] In a further embodiment, the cutting part includes a cutting linear module installed in a base, guide rods arranged on both sides of the base, and a cutting tool table sleeved on the guide rods and connected to the linear module.

[0014] The knife platform is a prior art and can be selected from a conventional silicon rod cutting mechanism. It can include a frame, a wire wheel and a pay-off and retractable wire wheel arranged in a predetermined orientation within the frame, and a cutting diamond wire mesh wound on the pay-off and retractable wire wheel and turned into a predetermined shape by the wire wheel. A driving motor is provided on the pay-off and retractable wire wheel.

[0015] In a further embodiment, a cutting wire groove adapted to the cutting net in the cutting tool station is opened on the positioning cylinder.

[0016] In a further embodiment, a positioning drive module is provided at the bottom of the positioning mechanism at either end.

[0017] In a further embodiment, the positioning drive module has the same structure as the cutting linear module, including:

[0018] A linear module motor is installed in the base;

[0019] The linear module lead screw is connected to the output end of the linear module motor;

[0022] The linear module slider of the positioning drive module is connected to the housing;

[0023] The base is provided with a slot adapted to the linear module slider, so that the linear module slider can extend outside the base to be connected with the cutting tool table and the housing.

[0024] In a further embodiment, a slide rail is provided on the base, and a slider connected to the housing and the cutting tool table is provided on the slide rail.

[0025] Beneficial effect: The utility model discloses a self-positioning silicon rod cutting tool table. The utility model positions the two ends of the silicon rod by designing a positioning cylinder. When the silicon rod enters the conical through groove, it is affected by the through groove and gradually adjusts its position until both ends are positioned. After positioning, the positioning cylinder drives multiple positioning rods to press against the silicon rod. When the cutting net is cutting, the cutting net can cut to the end of the silicon rod through the gap between the positioning rods and the cutting groove pre-opened on the positioning cylinder, thereby avoiding material waste caused by cutting the uncut part of the end.

[0035] The present application relates to a self-positioning silicon rod cutting tool table, which is explained in detail below through a specific implementation method.

[0036] A self-positioning silicon rod cutting tool table, comprising:

[0037] A base 1, and a cutting portion arranged on the base 1;

[0038] The two ends of the base 1 are provided with a positioning mechanism 4, and the positioning mechanism 4 includes:

[0039] A housing, arranged on the base 1;

[0040] A positioning cylinder 42 is connected to the shell and is located outside the shell. A through groove in the shape of a truncated cone is formed in the positioning cylinder 42. The diameter of the through groove gradually decreases from the side close to the tool table to the side away from the tool table. A plurality of through holes 423 extending into the shell are formed on the surface of the through groove in the positioning cylinder 42.

[0041] The positioning member 41 includes a positioning cylinder 411 installed in the housing, a positioning plate 412 arranged at the output end of the positioning cylinder 411 , and a plurality of positioning rods 413 installed on the positioning plate 412 and adapted to the through holes 423 .

[0042] The utility model positions the two ends of the silicon rod by designing a positioning cylinder 42. When the silicon rod enters the conical through groove, it is affected by the through groove and gradually adjusts its position until both ends are positioned. After positioning, the positioning cylinder 411 drives multiple positioning rods 413 to press against the silicon rod. When the cutting net is cutting, the cutting net can cut to the end of the silicon rod through the gap between the positioning rods 413 and the cutting line groove 422 pre-opened on the positioning cylinder 42, thereby avoiding material waste caused by cutting the uncut part of the end.

[0043] The cutting part includes a cutting linear module installed in a base 1, guide rods 2 arranged on both sides of the base 1, and a cutting tool table 3 sleeved on the guide rods 2 and connected to the linear module.

[0044] The knife platform is a prior art and can be selected from a conventional silicon rod cutting mechanism. It can include a frame, a wire wheel and a pay-off and retractable wire wheel arranged in a predetermined orientation within the frame, and a cutting diamond wire mesh wound on the pay-off and retractable wire wheel and turned into a predetermined shape by the wire wheel. A driving motor is provided on the pay-off and retractable wire wheel.

[0045] The positioning cylinder 42 is provided with a cutting line groove 422 adapted to the cutting net in the cutting tool table 3 .

[0046] A positioning drive module is provided at the bottom of the positioning mechanism 4 at either end.

[0047] The positioning drive module has the same structure as the cutting linear module, including:

[0048] A linear module motor is installed in the base 1;

[0049] The linear module lead screw is connected to the output end of the linear module motor;

[0050] The linear module slider is sleeved on the module lead screw;

[0051] The linear module slider of the cutting linear module is connected to the cutting tool table 3;

[0052] The linear module slider of the positioning drive module is connected to the housing;

[0053] The base 1 is provided with a slot adapted to the linear module slider, so that the linear module slider can extend outside the base 1 to be connected to the cutting tool table 3 and the housing.

[0054] The base 1 is provided with a slide rail, and the slide rail is provided with a slider connected with the housing and the cutting tool table 3.

[0055] Taking the example of the tic-tac-toe-shaped cutting net of the cutting tool table 3, a tic-tac-toe-shaped groove adapted to the tic-tac-toe-shaped cutting net is opened on the positioning cylinder 42 for the cutting net to enter, and at the same time, the distribution of multiple positioning rods 413 and through holes 423 can be adapted to the tic-tac-toe-shaped cutting net, thereby achieving the effect of cutting to the end.

[0056] Working principle description: During cutting, the initial position of the cutting net in the cutting table 3 is located in the positioning cylinder 42 in the positioning mechanism 4 which is not connected to the positioning drive module. Through the design of the cutting line groove 422, the cutting net can enter the positioning cylinder;

[0057] The silicon rod is placed in the positioning cylinders 42 at both ends, and the positioning mechanism 4 at one end is driven to move close to the other end through the positioning drive module. At this time, the silicon rod is affected by the through slot to adjust the angle position. After the adjustment is completed, the positioning cylinders 411 of the positioning mechanisms 4 at both ends drive the positioning plates 412 to move, so that the positioning rods 413 are against the silicon rod to complete the fixing work;

[0058] After the fixing is completed, the cutting blade 3 is driven to move by the cutting linear module, thereby driving the cutting net to move from one end to the other end, thereby completing the cutting of the silicon rod.

[0059] When the positioning drive module and the cutting linear module are working, the linear module lead screw is driven to rotate by the linear module motor, thereby driving the linear module slider to move, and further driving the housing and the cutting tool table 3 to move.
