Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crystal rod processing equipment, in particular to a diamond wire replacement tool for a crystal rod squaring machine. Background Art
[0002] After the silicon single crystal for solar cells is pulled, the single crystal square silicon rod with a smooth surface needs to be processed through three processes: cutting, squaring, and grinding. In the squaring process, the cut single crystal silicon rod is first placed horizontally on the workstation table of the squarer, and then the cutting mechanism composed of multiple guide wheels and diamond wires uses the diamond wire to rotate at high speed through the guide wheels and the workstation table moves from the outside to the inside to cut the round rod into a rectangular square rod blank. The diamond wire mentioned above is a ring wire, which is wound on four guide wheels (see Figure 1 The driving wheel, a pair of passive cutting wheels and a tensioning wheel are shown in the figure. During the cutting operation, the driving wheel drives the other guide wheels to rotate and cut the round rod. When the diamond wire reaches the end of its service life, the old wire needs to be removed and replaced with a new one.
[0003] At present, the replacement of old and new diamond wires mainly relies on operators entering the interior of the cutting mechanism (see Figure 2 The whole operation process has the following problems:
[0004] 1. The space between the left and right cutting heads of the cutting mechanism is narrow, which poses a great safety hazard for operators to enter and exit (prone to injury), and affects the efficiency of the replacement operation;
[0005] 2. There is a lot of dust accumulated on the left and right cutting heads of the cutting mechanism. Replacing the diamond wire is likely to cause dust, which will damage the respiratory system of the operator and pollute the environment. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model provides a diamond wire replacement tool for a crystal rod squaring machine, which enables an operator to quickly replace old diamond wires with new ones outside the cutting mechanism. The replacement operation is efficient and greatly reduces the safety hazards of easy injury to the operator and the respiratory system damage caused by dust.
[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0008] A diamond wire replacement tool for a crystal ingot squaring machine, comprising:
[0009] Rod body;
[0010] A handle connected to one end of the rod body;
[0011] a fork connected to the other end of the rod body and used for installing a new diamond wire; and
[0012] The hook head is connected to the rod body and arranged close to the fork, and is used for removing the old diamond wire and assisting the fork to complete the installation of the new diamond wire.
[0013] In one embodiment disclosed in the present application, the rod body has a length of 1 m and a diameter of 5 mm.
[0014] In one embodiment disclosed in the present application, the handle is integrally formed with the rod body.

[0037] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.
[0038] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0039] Embodiment 1:
[0040] See also Figure 3 and Figure 4 As shown, the utility model provides a diamond wire replacement tool for a crystal ingot squaring machine, comprising:
[0041] Rod body 10;
[0042] A handle 20 connected to one end of the rod body 10;
[0043] A fork 30 connected to the other end of the rod body 10 and used for installing a new diamond wire (not shown); and
[0044] The hook head 40 is connected to the rod body 10 and is disposed close to the fork 30 , and is used to remove the old diamond wire (not shown in the figure) and assist the fork 30 to complete the installation of the new diamond wire.
[0045] When in use, the operator holds the handle 20, inserts the tool into the cutting mechanism, uses the hook head 40 to hook the old diamond wire in an annular shape and peels it off from any guide wheel, then removes the tension-free and loose old diamond wire from other guide wheels, then hangs the new diamond wire in an annular shape on the fork 30 and pulls the new diamond wire with the other hand, inserts the tool into the cutting mechanism again, uses the fork 30 to wind the new diamond wire around any guide wheel, then uses the hook head 40 to hook the guide wheel to rotate it to a certain angle, so that the new diamond wire half covers the guide wheel, and then repeats this operation until the new diamond wire is wound around four guide wheels in an annular shape, that is, the installation of the new diamond wire is achieved. That is to say, through the cooperation of the fork 30 and the hook head 40, the operator can quickly replace the old and new diamond wires outside the cutting mechanism, saving the operator's time in and out of the equipment, improving the efficiency of the replacement operation, and greatly reducing the safety hazards of the operator's easy injury and the respiratory system damage caused by dust.
[0046] The rod body 10 is 1 meter long and 5 mm in diameter. The 1 meter length can ensure that the working range of the fork 30 and the hook head 40 fully covers the internal space of the cutting mechanism; the 5 mm diameter can ensure the strength of the rod body 10 and avoid bending, and at the same time can reduce the overall weight of the tool, which is conducive to reducing the fatigue of the operator after holding it for a long time.
[0047] The handle 20 is integrally formed with the rod body 10. That is, the handle 20 is formed by extending and bending one end of the rod body 10, and the manufacturing cost is low.
[0048] To prevent the new diamond wire from slipping off the fork 30 during installation, the fork 30 is V-shaped with an angle of 45°.
[0049] The hook head 40 has a tip 41. This makes it easier to hook the diamond wire and the guide wheel.
[0050] The connection point between the hook head 40 and the rod body 10 is located at 1 / 6 of the rod body 10. In this way, when the fork 30 releases a new diamond wire, it can quickly hook the guide wheel to rotate it, thereby improving the installation efficiency of the new diamond wire.
[0051] In this embodiment, the rod body 10, the handle 20, the fork 30 and the hook head 40 are all made of stainless steel. Stainless steel is not easily damaged and can extend the service life of the tool.
[0052] Embodiment 2:
[0053] See also Figure 5 As shown, the difference from the first embodiment is that the fork 30 is a U-shaped structure, and the angle of the bell mouth is 20-30 degrees. The U-shaped fork 30 will not block the new diamond wire, and can reduce the wear of the new diamond wire during installation.
[0054] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
