And therefore, the winding displacement efficiency is improved, and the winding displacement reliability is improved.

Description

Technical Field

[0001] The utility model relates to the technical field of slicers, in particular to a device for calibrating the position of a retractable wire wheel of a slicer. Background Art

[0002] Diamond wire slicer is a highly efficient machine tool for processing photovoltaic silicon wafers today. The main processing method is to use reciprocating diamond wire to cut silicon rods. The slicer includes a wire arrangement wheel. When the wire arrangement wheel is working, the wire arrangement wheel rotates and reciprocates along its axis to arrange the diamond wire.

[0003] In the prior art, during the wire winding process, since the wire arranging wheel reciprocates in a straight line along its axial direction to cooperate with the diamond wire winding, in order to prevent the diamond wire from being arranged to the extreme positions at both ends of the axial direction of the wire arranging wheel, it is necessary to judge whether the diamond wire has reached the extreme position of the wire arranging wheel by manual visual inspection. When the diamond wire reaches the extreme position, the moving direction of the wire arranging wheel needs to be manually adjusted. This method is inefficient and has large errors.

[0025] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0026] like Figure 1As shown, the embodiment of the utility model provides a device 1 for calibrating the position of the retractable wire wheel of a slicer, and the calibration device 1 is arranged in the slicer. Figure 2 As shown, the slicer also includes a wire arrangement device 2, wherein the wire arrangement device 2 includes a wire arrangement wheel 21 and an axial movement mechanism 22 for driving the wire arrangement wheel 21 to move axially back and forth. The wire arrangement wheel 21 rotates and moves linearly and axially back and forth during the wire arrangement process.

[0027] like Figure 1 As shown, the calibration device 1 includes a fixed column 15, a mounting frame 11, a telescopic unit 12, two contact sensors 13 and a control unit. The mounting frame 11 is connected to the fixed column 15, the fixed end of the telescopic unit 12 is connected to the mounting frame 11, the telescopic end of the telescopic unit 12 is connected to the two contact sensors 13, and the two contact sensors 13 can be respectively opposite to the two axial edges of the wire traversing wheel 21, and the control unit is electrically connected to the axial moving mechanism 22 of the wire traversing wheel 21 and the two contact sensors 13. In this embodiment, the telescopic unit 12 is a telescopic cylinder.

[0028] It should be noted that this embodiment does not involve improvement of the control process, and the existing control processes are all prior arts.

[0029] like Figure 1 As shown, the telescopic end of the telescopic unit 12 is connected to the two contact sensors 13 through the bracket 14. The bracket 14 includes a horizontal plate 141 and two connecting plates 142. One side of the horizontal plate 141 is connected to the telescopic end of the telescopic unit 12. The two connecting plates 142 are respectively arranged at two ends of the other side of the horizontal plate 141. The two contact sensors 13 are respectively arranged on the two connecting plates 142, and the two contact sensors 13 are arranged in opposite directions.

[0030] like Figure 1 As shown, the mounting frame 11 includes a first mounting plate 111 and a second mounting plate 112 which are detachably connected. The first mounting plate 111 is detachably connected to the fixing column 15 by screws, and the second mounting plate 112 is detachably connected to the telescopic unit 12. In order to adjust the installation angle of the contact sensor 13, an arc-shaped groove 1111 is provided on the first mounting plate 111.

[0032] Working principle of calibration device 1:

[0033] The calibration device 1 is located on one side of the wire arranging wheel 21. When the wire arranging wheel 21 is arranging wires, the telescopic unit 12 drives the contact sensor 13 to extend. At this time, the contact sensor 13 is opposite to the two axial edges of the wire arranging wheel 21, and the two axial edges are the two extreme positions of the wire arranging wheel 21. When arranging wires, the wire arranging wheel 21 rotates and the axial moving mechanism 22 drives the wire arranging wheel 21 to move axially back and forth. When the edge of the wire arranging wheel 21 abuts against one of the contact sensors 13, the contact sensor 13 sends a contact signal to the control unit. After the control unit receives the contact signal, the control unit drives the axial moving mechanism 22 to drive the wire arranging wheel 21 to move in a reverse linear direction to prevent the diamond wire from being entangled outside the extreme position of the wire arranging wheel 21. Therefore, the calibration device 1 improves the wire arranging efficiency and the reliability of the wire arranging.
