Description

Technical Field

[0001] The present invention belongs to the technical field of equipment for handling thin filaments, and particularly relates to winding a cutting wire onto a former, and more particularly to a winding device and a winding process for a cutting wire. Background Art

[0002] In the cutting process of hard and brittle materials such as silicon wafers, the precise winding quality of the cutting wire (such as a diamond wire) directly affects the stability of the cutting process and the material utilization rate.

[0003] In the related art, the winding devices for cutting wires generally have the technical pain points of inaccurate winding tension control: on the one hand, as the winding diameter increases, the cutting wire is prone to looseness and overlapping between layers, resulting in the "edge collapse" defect at the edge of the winding drum; on the other hand, when winding at high speed, the mechanical tension adjustment mechanism has a response lag, causing the cutting wire to break due to over-tightening or to become knotted due to slackness.

[0004] Therefore, how to improve the winding quality of the cutting wire is a technical problem that needs to be solved urgently at present.

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application. Therefore, the above description is not considered as information of the prior art. Summary of the Invention

[0006] The embodiments of the present disclosure at least provide a winding device and a winding process for a cutting wire.

[0007] In a first aspect, the embodiments of the present disclosure provide a winding device for a cutting wire, including: A driving mechanism; A hoisting and winding tooling for sleeving a hoisted winding drum on the driving shaft of the driving mechanism for winding; Wherein, the hoisting and winding tooling includes: A hoisting disc; A hoisting assembly, which is arranged on the hoisting disc and is used for clamping the top plate of the winding drum; A winding guide member, which is arranged on the hoisting assembly and is arranged along the axial direction of the winding drum; The winding guide member includes: A support plate, the end of which is slidably arranged on the hoisting assembly and is arranged along the axial direction of the winding drum; A U-shaped rubber strip, which is connected to the hoisting assembly through a telescopic block; One side of the U-shaped rubber strip is slidably arranged on the support plate, and the other side faces the winding drum; When the cutting wire passes through the U-shaped rubber strip and is wound on the winding drum, it reciprocates along the U-shaped rubber strip to adjust the tension during the winding of the cutting wire.

[0008] In an alternative embodiment, a spring plunger is provided at one end of the telescopic block close to the top plate of the winding drum. The top plate of the winding drum is frustum-shaped. The spring plunger abuts against the side wall of the top plate of the winding drum. When the cutting line moves to the end of the U-shaped rubber strip, the telescopic block is pulled to slide downward by the U-shaped rubber strip, thereby driving the spring plunger to push the support plate to move radially outward along the winding drum.

[0009] In an alternative embodiment, the spring plunger includes: A first return spring and an abutting block; A groove is formed in the telescopic block. The abutting block is elastically connected in the groove through the first return spring.

[0010] In an alternative embodiment, the lifting disc is axially provided with a slot for the support plate to be inserted. The support plate is slidably arranged in the slot and is elastically connected to the bottom of the slot through a second return spring.

[0011] In an alternative embodiment, two oppositely arranged covering plates extend outward from the support plate, and the two covering plates form a sliding space for accommodating one side of the U-shaped rubber strip.

[0012] In an alternative embodiment, the distance between the bottom of the U-shaped rubber strip and the bottom plate of the winding drum is h1; The thickness of the top plate of the winding drum is h2; Wherein, h1 < h2, and the units of h1 and h2 are cm.

[0013] In an alternative embodiment, the lifting assembly includes: A lifting rod; A pull plate, which is arranged at the end of the lifting rod; Two oppositely arranged clamping blocks for clamping the top plate of the winding drum; The clamping block is connected to the pull plate through a connecting rod; The middle part of the connecting rod is hinged to the top of the lifting disc.

[0014] In a second aspect, the embodiments of the present disclosure further provide a winding process applied to the winding device for the cutting line as described above. The winding process includes: Lifting the winding drum by a lifting and winding tooling; Sleeving the winding drum on the drive shaft of the drive mechanism; Pass the cutting line through the U-shaped rubber strip and then fix it on the winding drum. Start the driving mechanism to drive the winding drum to start rotating and wind up the cutting line.

[0015] In an optional implementation manner, a spring plunger is provided at one end of the telescopic block close to the top plate of the winding drum. The top plate of the winding drum is frustum-shaped. The spring plunger abuts against the side wall of the top plate of the winding drum. When winding up the cutting line, when the cutting line moves to the end of the U-shaped rubber strip, the U-shaped rubber strip pulls the telescopic block to slide downward, thereby driving the spring plunger to push the support plate to move radially outward along the winding drum.

[0016] In an optional implementation manner, the spring plunger includes: A first return spring and a abutting block; The telescopic block is provided with a groove. The abutting block is elastically connected in the groove through the first return spring.

[0017] The beneficial effect of the present invention is that the winding device and winding process for the cutting line, through the linkage design of the U-shaped rubber strip and the telescopic block, during the winding process of the cutting line, through the elastic deformation of the rubber material and the sliding displacement of the telescopic block, the fluctuation of the cutting line tension is compensated in real time. When the cutting line moves to the end of the U-shaped rubber strip, the bending resilience of the rubber strip and the downward sliding of the telescopic block form a dynamic balance, effectively avoiding the problems of the cutting line being too tight and breaking or being loose and piling up caused by the response delay of the traditional rigid tension mechanism.

[0029] It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0030] Hereinafter, some embodiments of the present invention will be described in detail with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0031] Please refer to Figure 1 and Figure 2 , at least one embodiment provides a winding device for a cutting line, including: a driving mechanism; a hoisting and winding tooling 100 for sleeving a hoisted winding drum 200 on a driving shaft of the driving mechanism for winding.

[0032] Among them, the hoisting and winding tooling 100 includes: a hoisting disc 110; a hoisting assembly 120, which is arranged on the hoisting disc 110 and is used for clamping the top plate 210 of the winding drum 200; a winding guide 130, which is arranged on the hoisting assembly 120 and is arranged along the axial direction of the winding drum 200; the winding guide 130 includes: a support plate 131, the end of which is slidably arranged on the hoisting assembly 120 and is arranged along the axial direction of the winding drum; a U-shaped rubber strip 132, which is connected to the hoisting assembly 120 through a telescopic block 133; one side of the U-shaped rubber strip 132 is slidably arranged on the support plate 131, and the other side faces the winding drum; when the cutting wire passes through the U-shaped rubber strip 132 and is wound on the winding drum, it reciprocates along the U-shaped rubber strip 132 to adjust the tension when the cutting wire is wound.

[0033] Through the linkage design of the U-shaped rubber strip 132 and the telescopic block 133, during the winding process of the cutting wire, through the elastic deformation of the rubber material and the sliding displacement of the telescopic block 133, the fluctuation of the cutting wire tension is compensated in real time. When the cutting wire moves to the end of the U-shaped rubber strip 132, the bending resilience of the rubber strip and the downward sliding of the telescopic block 133 form a dynamic balance, effectively avoiding the problems of the cutting wire being too tight and breaking or being loose and piling up caused by the response delay of the traditional rigid tension mechanism.

[0034] It should be noted that since the conventional cutting wire is composed of a single structure, however, the cutting wire material for multi-wire cutting of silicon carbide is relatively hard, and the wire is easily worn during the actual processing, and the wire on the surface is easily worn, resulting in a relatively short service life of the wire.

[0035] The cutting wire provided in this embodiment is formed by winding multiple wires with a diameter of 0.005 - 0.01 mm and bonding with an adhesive to form a composite wire with a diameter of 0.11 - 0.25 mm. Even if the surface of the wire saw is damaged to a certain extent during use, its main structure and strength are still good, greatly increasing the service life of the wire saw.

[0036] Please refer to Figure 2 and Figure 3 , a spring plunger 134 is arranged at one end of the telescopic block 133 close to the top plate 210 of the winding drum 200; the top plate 210 of the winding drum 200 is frustum-shaped; the spring plunger 134 abuts against the side wall of the top plate 210 of the winding drum 200; when the cutting wire moves to the end of the U-shaped rubber strip 132, the U-shaped rubber strip 132 pulls the telescopic block 133 to slide downward, thereby driving the spring plunger 134 to push the support plate 131 to move radially outward along the winding drum.

[0037] When the cutting line moves to the bottom end of the take-up reel 200, the next layer of winding needs to be carried out. At this time, by pulling the U-shaped rubber strip 132, the support plate 131 is moved outwards, so that it is tightened at the beginning of the next layer of winding, avoiding looseness at the end, thereby improving the winding quality of the cutting line.

[0038] Please continue to refer to Figure 3 , the spring plunger 134 includes: a first return spring 134a and a abutting block 134b; the telescopic block 133 is provided with a groove; the abutting block 134b is elastically connected in the groove through the first return spring 134a.

[0039] When pulling the U-shaped rubber strip 132, through the cooperation of the abutting block 134b and the side wall of the top plate 210, the support plate 131 is pushed outwards to tighten the cutting line, so that the end is wound more tightly, improving the winding quality.

[0040] Please refer to Figure 2 and Figure 3 , the lifting disc 110 is axially provided with a slot for the support plate 131 to insert; the support plate 131 is slidably arranged in the slot and is elastically connected to the bottom of the slot through a second return spring.

[0041] Through the elastic reset function of the second return spring, it is ensured that the support plate 131 automatically returns to its original position after radial expansion, avoiding wire arrangement misalignment caused by the jamming of the support plate 131.

[0042] In a preferred embodiment, the support plate 131 extends outwards two oppositely arranged covering plates, and the two covering plates form a sliding space for accommodating one side of the U-shaped rubber strip 132.

[0043] The movement of the U-shaped rubber strip 132 is limited by the sliding space, avoiding lateral displacement of the rubber strip due to wire pulling.

[0044] Please refer to Figure 2 , the distance between the bottom of the U-shaped rubber strip 132 and the bottom plate 220 of the take-up reel is h1; the thickness of the top plate 210 of the take-up reel is h2; wherein, h1 < h2, and the units of h1 and h2 are cm.

[0045] Please refer to Figure 4 , the lifting assembly 120 includes: a lifting rod 121; a pulling plate 122, which is arranged at the end of the lifting rod 121; two oppositely arranged clamping blocks 123, and used for clamping the top plate 210 of the take-up reel 200; the clamping blocks 123 are connected to the pulling plate 122 through a connecting rod 124; the middle of the connecting rod 124 is hinged to the top of the lifting disc 110.

[0046] Please refer toFigure 5 , at least one embodiment provides a winding process applied to the winding device for the cutting line as described above. The winding process includes: S110, hoisting the winding drum 200 by a hoisting and winding tool; S120, sleeving the winding drum 200 on the drive shaft of the drive mechanism; S130, passing the cutting line through the U-shaped rubber strip 132 and fixing it on the winding drum 200; S140, starting the drive mechanism to drive the winding drum 200 to start rotating and wind the cutting line.

[0047] Among them, please refer to Figure 2 and Figure 3 , one end of the telescopic block 133 close to the top plate 210 of the winding drum 200 is provided with a spring plunger 134; the top plate 210 of the winding drum 200 is frustum-shaped; the spring plunger 134 abuts against the side wall of the top plate 210 of the winding drum 200; when winding the cutting line, when the cutting line moves to the end of the U-shaped rubber strip 132, the telescopic block 133 is pulled to slide downward by the U-shaped rubber strip 132, thereby driving the spring plunger 134 to push the support plate 131 to move radially outward along the winding drum.

[0048] When the cutting line moves to the bottom end of the winding drum 200, it is necessary to add the next layer of winding. At this time, by pulling the U-shaped rubber strip 132, the support plate 131 is moved outward to tighten the start of the next layer of winding, avoiding looseness at the end, thereby improving the winding quality of the cutting line.

[0049] Please refer to Figure 2 and Figure 3 , the spring plunger 134 includes: a first return spring 134a and a abutting block 134b; the telescopic block 133 is provided with a groove; the abutting block 134b is elastically connected in the groove through the first return spring 134a.

[0050] In summary, the present invention provides a winding device and a winding process for a cutting wire. The winding device includes: a driving mechanism; a hoisting and winding tooling 100 for sleeving the hoisted winding drum 200 on the driving shaft of the driving mechanism for winding. The hoisting and winding tooling 100 includes: a hoisting disc 110; a hoisting component 120 disposed on the hoisting disc 110 and used for clamping the top plate 210 of the winding drum 200; a winding guide member 130 disposed on the hoisting component 120 and arranged along the axial direction of the winding drum. The winding guide member 130 includes: a support plate 131, the end of which is slidably disposed on the hoisting component 120 and arranged along the axial direction of the winding drum; a U-shaped rubber strip 132 connected to the hoisting component 120 through a telescopic block 133. One side of the U-shaped rubber strip 132 is slidably disposed on the support plate 131, and the other side faces the winding drum. When the cutting wire passes through the U-shaped rubber strip 132 and is wound on the winding drum, it reciprocates along the U-shaped rubber strip 132 to adjust the tension during the winding of the cutting wire. Through the linkage design of the U-shaped rubber strip 132 and the telescopic block 133, during the winding process of the cutting wire, the elastic deformation of the rubber material and the sliding displacement of the telescopic block 133 are used to compensate for the fluctuation of the cutting wire tension in real time. When the cutting wire moves to the end of the U-shaped rubber strip 132, the bending resilience of the rubber strip and the downward sliding of the telescopic block 133 form a dynamic balance, effectively avoiding the problems of the cutting wire being too tight and breaking or being slack and piling up caused by the response delay of the traditional rigid tension mechanism.
