[0002] Single crystal silicon is a good semiconductor material used to manufacture semiconductor devices, solar cells, chips, etc. It is made of high-purity polycrystalline silicon pulled in a single crystal furnace and is the purest substance that humans have obtained. A trace amount of IIIA group elements is added to single crystal silicon to form a P-type semiconductor, and a trace amount of VA group elements is added to form an N-type. When N-type and P-type semiconductors are combined together, they can be made into solar cells, which convert radiation energy into electrical energy.

[0003] In the past, during the slicing process, when loading silicon crystal rods, the operator needed to use a transfer cart to transport the silicon crystal rods to the loading port of the wire saw, and the operator manually pushed the silicon crystal rods into the wire saw to complete the loading process of the silicon crystal rods. After the wire saw cuts the silicon crystal rods, the silicon crystal rods need to be unloaded manually. The hook with the cable is manually hung on the base of the silicon crystal rod, and the operator turns the cable turntable to transfer the silicon crystal rod to the transfer cart. In actual operation, the weight of each silicon crystal rod is as high as 80-160 kilograms. After the silicon crystal rod is cut, it needs to be supported. If it is operated manually, it will not only be extremely labor-intensive and inefficient, but also affect the efficiency of logistics turnover and easily cause damage to the silicon crystal rod.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] The present embodiment provides a double-grip device for automatically picking up and placing silicon crystal rods. The double-grip device can grab uncut silicon crystal rods and cut silicon crystal rods, and transfer the positions of the silicon crystal rods. During this process, no manual operation is required, which reduces the labor intensity of the operator and greatly improves the efficiency of logistics turnover. It can also support the cut silicon crystal rods, which is beneficial to the subsequent transfer of the silicon crystal rods.

[0029] Combination Figures 1 to 5 As shown, the dual-gripper device for automatically picking up and placing silicon crystal rods in this embodiment includes a gripper portion 10, a drive portion 20 and a support portion 30. The gripper portion 10 grips and positions the silicon crystal rod, and the drive portion 20 drives the gripper portion 10 to move to achieve the position transfer of the silicon crystal rod, while the support portion 30 can support the cut silicon crystal rod so that the silicon crystal rod can be subsequently transferred.

[0030] In this embodiment, the double-gripper device for automatically picking up and placing silicon crystal rods also includes a mounting frame 40, and the gripper portion 10, the drive portion 20 and the support portion 30 are all arranged on the mounting frame 40, and a liquid receiving tray 50 is arranged on the mounting frame 40. The liquid receiving tray 50 is located below the gripper portion 10 to receive liquid from the silicon crystal rod. During the process of grabbing and transferring the silicon crystal rod, liquid will flow out of the silicon crystal rod, and the outflowing liquid will enter the liquid receiving tray 50 to prevent the liquid from dripping directly, which is beneficial to the protection of the on-site environment.

[0031] Specifically, the surface of the liquid receiving tray 50 is an inclined surface, and a plurality of liquid inlet holes 51 are provided on the inclined surface to introduce the liquid into the liquid receiving tray 50 . The existence of the inclined surface is conducive to liquid receiving treatment of the silicon crystal rod, so that the liquid flows into the liquid receiving tray 50 through the liquid inlet holes 51 .

[0032] Combination Figure 1 and Figure 3 As shown, the number of gripping parts 10 in this embodiment is two groups and they are arranged in parallel. One gripping part 10 grabs the silicon crystal rod before cutting, and the other gripping part 10 grabs the silicon crystal rod after cutting. The two groups of gripping parts 10 have the same structure, realizing the automatic picking and placing operation of the silicon crystal rod.

[0033] In this embodiment, the gripper part 10 includes a gripper driver 11, a clamping plate 12 and a positioning block 13. The gripper driver 11 drives the positioning block 13 to enter the silicon crystal rod through the clamping plate 12 to grasp and position the silicon crystal rod. There are several holes on the silicon crystal rod of this embodiment, so the silicon crystal rod can be positioned by the positioning block 13, and the gripper driver 11 can clamp the silicon crystal rod through the clamping plate 12, thereby achieving the clamping and positioning of the silicon crystal rod.

[0034] Specifically, there are a plurality of positioning blocks 13 evenly distributed on the clamping plate 12 . The evenly distributed positioning blocks 13 can position the silicon crystal rod from multiple positions to ensure the positioning effect of the silicon crystal rod.

[0035] Combination Figure 1 and Figure 4 As shown, the driving part 20 of this embodiment is in two groups, and corresponds to the gripping part 10 one by one to drive the gripping part 10. The driving part 20 of this embodiment is a screw driving module, which drives the gripping part 10 to transfer the position of the silicon crystal rod.

[0036] Combination Figure 1 , Figure 2 as well as Figure 5 As shown, the supporting portion 30 of this embodiment corresponds to the position of the gripping portion 10 after the silicon crystal rod is cut. The supporting portion 30 includes a supporting driver 31 and a supporting member 32. The supporting driver 31 drives the supporting member 32 to support the bottom of the silicon crystal rod after cutting. The cut silicon crystal rod is prone to looseness, so a supporting member 32 is arranged under the silicon crystal rod, and the supporting member 32 is driven up by the supporting driver 31 to support the bottom of the silicon crystal rod.

[0037] In this embodiment, there are two supporting members 32, which are connected to the supporting driver 31 via a connecting sheet metal 60. The supporting members 32 are foam, which is used to support the bottom of the silicon crystal rod, and can effectively prevent the silicon crystal rod from being damaged when the silicon crystal rod is lifted.

[0038] In this embodiment, the gripper driver 11 and the support driver 31 are both cylinders.

[0039] In actual use, the double-gripper device for automatically picking up and placing silicon crystal rods of this embodiment uses the gripper portion 10 to grab the silicon crystal rod, and after grabbing, the position of the silicon crystal rod is transferred under the action of the driving portion 20. During this process, no manual operation is required, which reduces the labor intensity of the operator and greatly improves the efficiency of logistics turnover. The supporting portion 30 can also support the cut silicon crystal rods, which is beneficial to the subsequent transfer of the silicon crystal rods.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
