Description

TECHNICAL FIELD

[0001] The present application relates to the field of multi-wire cutting, especially to the technical field of solar cell, and particularly to a multi-wire cutting wire distribution method and a wire distribution device thereof. BACKGROUND

[0002] At present, in many fields, rod-shaped materials are cut and processed to obtain thin sheet-shaped materials of predetermined thickness. There are various methods for cutting rod-shaped materials, among which the two main cutting methods are as follows: one is inner circle cutting method, that is, using a ring-shaped thin sheet-shaped inner diameter saw and abrasive to cut the sheet; the other is multi-wire cutting method, that is, by high-speed reciprocating movement of the metal wire, the rod material is cut into thin sheets in an orderly manner. Since the multi-wire cutting method has higher efficiency, it has basically replaced the inner circle cutting method.

[0003] Multi-wire cutting technology is the main means for cutting and processing hard materials into thin sheets. When cutting rod materials, at the positions close to the entry and exit lines at both ends of the rod material, due to the shaking of the steel wire, the thickness of the thin sheets at these positions is not uniform, resulting in a large number of products with poor thickness. Therefore, the common method in the industry is to reserve two thicker sheets at both free ends of the rod material. If the rod material is composed of two or three silicon blocks spliced together, thick sheets need to be reserved on both sides of each splice during the cutting process. Therefore, the wire distribution needs to be left empty at the wire net corresponding to the thick sheets, resulting in "wire net holes", that is, the empty space with a width greater than 2 times the width of the cutting wire slot.

[0004] During the multi-wire cutting process, the wire net holes are generally formed manually by manual wire shifting. With the increasing thinness of the cut sheets and the fineness of the cutting steel wire, in the cutting process of multi-spliced blocks, the operation of the small and wide distribution of the wire net is increasingly difficult for the human eye to distinguish. The most common wire net width is about 2-3 mm, and the human eye cannot control it stably if it is smaller. At the position of the wire net hole, the cutting wire spacing is widened, and the steel wire net at this position is not parallel to the wire distribution. There is a diagonal cutting wire, and the greater the width of the wire net hole, the greater the inclination of the diagonal steel wire, and the greater the impact on the cutting material. The larger diagonal cutting wire may cause wire breakage during cutting. For cutting of multi-spliced rod materials, due to the existence of several or even dozens of wire net holes, manual operation is increasingly difficult. On the other hand, due to the limited resolution of the human eye, the shifting distance of the wire between the two wire wheels differs by several wire slots, further increasing the spacing between the cutting wires, which will cause the silicon sheet cutting surface at this position to present a trapezoidal surface instead of a flat surface, increasing the material loss rate and the defective rate. SUMMARY

[0039] Step (6) Repeat steps (2) to (5) to form a wire mesh with a width of d=3mm while wiring on the main roller 2;

[0040] This will result in a cutting wire mesh distribution on the main roller 2, with each interval of wire width L=30mm forming a dividing wire mesh hole width d=3mm. Example 2

[0041] like Figs. 1-2 As shown, this invention relates to a wire mesh wiring device for multi-wire cutting and a wiring method thereof, applicable to the wire mesh wiring process of current two-main-roll, three-main-roll, and four-main-roll cutting machines. The figure shows a schematic diagram of wire mesh wiring in the form of a three-main-roll cutting machine.

[0042] A multi-wire cutting mesh wiring device, which controls the steel wire 6 to rotate around the main roller 2 one revolution at a time, so that the steel wire is regularly wound into the wire groove, and the wire hole is pulled out simultaneously while the mesh is being laid.

[0043] The wiring device includes a rotating track 1, a track positioning bracket 3, an automatic stepping unit 4, and a wire feeding unit 5. The main roller 2 is located inside the rotating track 1, which is a closed loop track with the first and second ends connected. The plane of the rotating track 1 forms an angle of 45-135 degrees with the axial direction of the main roller 2, preferably 90 degrees. The wire feeding unit 5 and the automatic stepping unit 4 move around the main roller 2 along the rotating track 1.

[0044] The rotating track 1 is divided into left and right parts, which are easily connected by left and right track connectors 7.

[0045] The automatic stepping unit 4 rotates around the rotating track 1 via one or more transmission methods, including the drive gear 9, chain, belt, and friction wheel. The drive gear 9 can drive the automatic stepping unit 4 to perform circular motion along the rotating track 1. Specifically, the rotating track 1 may have a gear ring that meshes with the drive gear 9. The rotation of the drive gear 9 drives the automatic stepping unit 4 to perform circular motion along the rotating track 1.

[0046] The wire feeding unit 5 is fixed on the moving ring of the rotating track 1 by the automatic stepping unit 4, and performs synchronous circular motion around the main roller 2 along the rotating track 1.

[0047] The wire feeding unit 5 includes a wire feeding wheel 51, a wire guiding wheel 52, and a steering wheel 53. The steel wire 6 on the wire feeding wheel 51 is wound onto the main roller 2 through the wire guiding wheel 52 and the steering wheel 53.

[0048] The track positioning bracket 3 is used to position the rotating track 1 on the slicer and fix it to the inner wall of the equipment, so that the entire plane of the rotating track 1 is perpendicular to the axis of the main roller 2.

[0049] The automatic stepping unit 4 is used to guide the steel wire 6 to jump from one wire trough to an adjacent wire trough, or to guide the steel wire 6 to cross a specific wire mesh hole width d from one wire trough for wiring.

[0050] The wire clamp 8 is used to fix the free end of the steel wire 6 onto the main roller 2. The automatic stepper controller 41 is used to control the automatic stepper rod 42 to perform axial feed motion.

[0051] The working process of this embodiment is as follows:

[0052] The wire dispenser device drives the steel wire 6 to rotate one round around the main roller 2, the automatic stepping unit 4 guides the steel wire 6 to step forward / backward one distance T of the wire slot and guides the steel wire 6 to be evenly wound into the corresponding slot of the main roller 2. The wire net forming action can be realized in two ways:

[0053] 1) Manual mode: when reaching the wire netting position, the rotation of the main roller 2 is manually paused first, the automatic stepping rod 42 is manually adjusted to make the stepper step forward the wire net hole width d;

[0054] 2) Automatic mode: in the automatic wiring, the cutting area width L and the wire net hole width d are set, and the wire net hole width d is triggered to step forward every time the continuous wiring distance L is reached, thus the action of wiring the wire net containing the wire net hole is completed.

[0055] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited by the above examples, the above examples and descriptions in the specification are only preferred examples of the application and are not intended to limit the application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the application, and these changes and improvements all fall within the scope of the claimed application. The scope of the application is defined by the appended claims and their equivalents.
