Winding equipment and winding process for cutting lines

Abstract

The present invention belongs to the technical field of equipment for handling filaments, and specifically relates to winding cutting wires onto a former, and more particularly to a winding device and winding process for cutting wires, wherein the winding device includes: a driving mechanism; a hoisting and winding tool; the hoisting and winding tool includes: a hoisting disc; a hoisting assembly; a winding guide; the winding guide includes: a support plate; a U-shaped rubber strip, which is connected to the hoisting assembly via a telescopic block. Through the linkage design of the U-shaped rubber strip and the telescopic block, the fluctuation of the cutting wire tension is compensated in real time during the winding process of the cutting wire through the elastic deformation of the rubber material and the sliding displacement of the telescopic block. When the cutting wire moves to the end of the U-shaped rubber strip, the bending rebound force of the rubber strip and the downward sliding of the telescopic block form a dynamic balance, which effectively avoids the problem of the cutting wire being too tight and broken or loose and accumulated due to the response delay of the traditional rigid tension mechanism.

Description

Technical Field

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

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

[0003] The cutting wire winding equipment in related technologies generally has the technical pain point of inaccurate winding tension control: on the one hand, as the winding diameter increases, the cutting wire layers are prone to loosening and overlapping, resulting in "collapsed edge" defects on the edge of the roll; on the other hand, the mechanical tension adjustment mechanism has a response lag during high-speed winding, causing the cutting wire to be too tight and broken or loose and knotted.

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

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute 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 line.

[0007] In a first aspect, an embodiment of the present disclosure provides a winding device for a cutting line, comprising:

[0008] Drive mechanism;

[0009] A hoisting and winding tool is used to sleeve the hoisted winding drum onto the driving shaft of the driving mechanism for winding;

[0010] Among them, the lifting and winding tooling includes:

[0011] Lifting tray;

[0012] A hoisting assembly, which is arranged on the hoisting plate and is used to clamp the top plate of the winding drum;

[0013] A winding guide, which is provided on the hoisting assembly and arranged along the axial direction of the winding drum;

[0014] The reel guide comprises:

[0015] A support plate, an end of which is slidably disposed on the hoisting assembly and arranged along the axial direction of the winding drum;

[0016] A U-shaped rubber strip connected to the lifting assembly via a telescopic block;

[0017] One side of the U-shaped rubber strip is slidably arranged on the support plate, and the other side is arranged toward the winding drum;

[0018] When the cutting line 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 of the cutting line when it is wound.

[0019] In an optional embodiment, a spring plunger is provided at one end of the telescopic block close to the top plate of the winding drum;

[0020] The top plate of the winding drum is in the shape of a truncated cone;

[0021] The spring plunger abuts against the side wall of the top plate of the winding drum;

[0022] 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.

[0023] In an optional embodiment, the spring plunger comprises:

[0024] a first return spring and a supporting block;

[0025] The telescopic block is provided with a groove;

[0026] The abutting block is elastically connected in the groove via the first return spring.

[0027] In an optional embodiment, the lifting plate is provided with a slot for inserting the support plate along the axial direction;

[0028] The support plate is slidably arranged in the slot and is elastically connected to the slot bottom via a second return spring.

[0029] In an optional embodiment, two oppositely disposed covering plates extend outward from the support plate, and the two covering plates form a sliding space for accommodating one side edge of the U-shaped rubber strip.

[0030] In an optional embodiment, the distance between the bottom of the U-shaped rubber strip and the bottom plate of the winding drum is h1;

[0031] The thickness of the top plate of the winding drum is h2;

[0032] Here, h1<h2, and the units of h1 and h2 are cm.

[0033] In an optional embodiment, the hoisting assembly includes:

[0034] Lifting rod;

[0035] a pull plate, which is arranged at the end of the lifting rod;

[0036] Two clamping blocks are arranged opposite to each other and are used to clamp the top plate of the winding drum;

[0037] The clamping block is connected to the pull plate via a connecting rod;

[0038] The middle portion of the connecting rod is hinged to the top of the lifting plate.

[0039] In a second aspect, the embodiments of the present disclosure further provide a winding process applied to the above-mentioned winding device for the cutting wire, the winding process comprising:

[0040] Hoist the reel drum through the hoisting and reeling tooling;

[0041] Sleeve the take-up drum onto the drive shaft of the drive mechanism;

[0042] Pass the cutting line through the U-shaped rubber strip and fix it on the take-up drum;

[0043] Turn on the drive mechanism to drive the take-up drum to start rotating and reel in the cutting wire.

[0044] In an optional embodiment, a spring plunger is provided at one end of the telescopic block close to the top plate of the winding drum;

[0045] The top plate of the winding drum is in the shape of a truncated cone;

[0046] The spring plunger abuts against the side wall of the top plate of the winding drum;

[0047] When the cutting line is wound up, 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.

[0048] In an optional embodiment, the spring plunger comprises:

[0049] a first return spring and a supporting block;

[0050] The telescopic block is provided with a groove;

[0051] The abutting block is elastically connected in the groove via the first return spring.

[0052] The beneficial effect of the present invention is that the cutting line winding device and winding process utilizes a coordinated design between a U-shaped rubber strip and a telescopic block. During the winding process, the elastic deformation of the rubber material and the sliding displacement of the telescopic block compensate for fluctuations in the cutting line tension in real time. When the cutting line reaches the end of the U-shaped rubber strip, the bending rebound force of the rubber strip and the downward sliding displacement of the telescopic block form a dynamic balance, effectively avoiding the problem of overtightening and breakage of the cutting line or accumulation of loose wire caused by the response delay of traditional rigid tensioning mechanisms.

[0068] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0069] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0070] See also Figure 1 and Figure 2 At least one embodiment provides a winding device for a cutting line, comprising: a driving mechanism; a hoisting and winding tool 100, for sleeve-mounting a hoisted winding drum 200 on a driving shaft of the driving mechanism for winding.

[0071] Among them, the lifting and winding tooling 100 includes: a lifting disk 110; a lifting component 120, which is arranged on the lifting disk 110 and is used to clamp the top plate 210 of the winding drum 200; a winding guide 130, which is arranged on the lifting component 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 lifting component 120 and is arranged along the axial direction of the winding drum; a U-shaped rubber strip 132, which is connected to the lifting component 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 is arranged toward the winding drum; when the cutting line 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 of the cutting line when it is wound.

[0072] The coordinated design of the U-shaped rubber strip 132 and the telescopic block 133 compensates for fluctuations in the cutting line's tension during the winding process through the elastic deformation of the rubber material and the sliding displacement of the telescopic block 133. When the cutting line reaches the end of the U-shaped rubber strip 132, the bending and rebound force of the rubber strip and the downward sliding of the telescopic block 133 form a dynamic balance, effectively avoiding the response delay of traditional rigid tensioning mechanisms that can lead to over-tightening and breakage of the cutting line or accumulation of loose wire.

[0073] It should be noted that since conventional cutting wires are composed of a single structure, the cutting wire material for multi-wire cutting of silicon carbide is relatively hard. During the actual processing process, the wire is easily worn out, and the surface wire is easily worn out, resulting in a relatively short wire life.

[0074] The cutting wire provided in this embodiment is formed by winding multiple strands of 0.005-0.01mm diameter wire and bonding them with an adhesive to form a composite wire with a diameter of 0.11-0.25mm. Even if the surface of the wire saw is damaged to a certain extent during use, its main structure and strength are still very good, which greatly increases the service life of the wire saw.

[0075] See also Figure 2 and Figure 3 A spring plunger 134 is provided 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 in the shape of a truncated cone; the spring plunger 134 abuts against the side wall of the top plate 210 of the winding drum 200; when the cutting line moves to the end of the U-shaped rubber strip 132, the telescopic block 133 is pulled downward by the U-shaped rubber strip 132, thereby driving the spring plunger 134 to push the support plate 131 to move outward along the radial direction of the winding drum.

[0076] When the cutting line moves to the bottom end of the winding drum 200, the next layer needs to be wound. At this time, by pulling the U-shaped rubber strip 132, the support plate 131 moves outward, so that the next layer of winding is tightened at the beginning to avoid loosening of the end, thereby improving the winding quality of the cutting line.

[0077] Please continue reading Figure 3 The spring plunger 134 includes: a first return spring 134a and a supporting block 134b; the telescopic block 133 is provided with a groove; the supporting block 134b is elastically connected to the groove through the first return spring 134a.

[0078] When the U-shaped rubber strip 132 is pulled, the support plate 131 is pushed outward by the cooperation between the supporting block 134b and the side wall of the top plate 210, and the cutting line is tightened, so that the end portion is rolled up more tightly and the rolling quality is improved.

[0079] See also Figure 2 and Figure 3 The lifting plate 110 is provided with a slot for inserting the support plate 131 along the axial direction; 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.

[0080] The elastic return function of the second return spring ensures that the support plate 131 automatically returns to its original position after radial expansion, thereby avoiding misalignment of the cable caused by the support plate 131 being stuck.

[0081] In a preferred embodiment, two oppositely disposed covering plates extend outward from the support plate 131 , and the two covering plates form a sliding space for accommodating one side edge of the U-shaped rubber strip 132 .

[0082] The movement of the U-shaped rubber strip 132 is limited by the sliding space to prevent the rubber strip from being laterally offset due to the pulling of the wire.

[0083] See also Figure 2 The distance between the bottom of the U-shaped rubber strip 132 and the bottom plate 220 of the winding drum is h1; the thickness of the top plate 210 of the winding drum is h2; wherein h1<h2, and the units of h1 and h2 are cm.

[0084] See also Figure 4 The lifting assembly 120 includes: a lifting rod 121; a pull plate 122, which is arranged at the end of the lifting rod 121; two oppositely arranged clamping blocks 123, and used to clamp the top plate 210 of the winding drum 200; the clamping block 123 is connected to the pull plate 122 through a connecting rod 124; the middle part of the connecting rod 124 is hinged to the top of the lifting plate 110.

[0085] See also Figure 5 At least one embodiment provides a winding process for the winding device for the cutting line as described above, the winding process comprising:

[0086] S110, hoisting the reel 200 by hoisting the reeling tool;

[0087] S120, sleeve the take-up drum 200 onto the drive shaft of the drive mechanism;

[0088] S130, passing the cutting line through the U-shaped rubber strip 132 and fixing it on the winding drum 200;

[0089] S140, turning on the driving mechanism to drive the winding drum 200 to start rotating and winding the cutting wire.

[0090] Among them, see Figure 2 and Figure 3 A spring plunger 134 is provided 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 in the shape of a truncated cone; the spring plunger 134 abuts against the side wall of the top plate 210 of the winding drum 200; when the cutting line is wound up, when the cutting line moves to the end of the U-shaped rubber strip 132, the telescopic block 133 is pulled downward by the U-shaped rubber strip 132, thereby driving the spring plunger 134 to push the support plate 131 to move outward along the radial direction of the winding drum.

[0091] When the cutting line moves to the bottom end of the winding drum 200, it is necessary to increase the winding of the next layer. At this time, by pulling the U-shaped rubber strip 132, the support plate 131 moves outward, so that the next layer of winding is tightened at the beginning to avoid loosening of the end, thereby improving the winding quality of the cutting line.

[0092] See also Figure 2 and Figure 3 The spring plunger 134 includes: a first return spring 134a and a supporting block 134b; the telescopic block 133 is provided with a groove; the supporting block 134b is elastically connected to the groove through the first return spring 134a.

[0093] In summary, the present invention provides a winding device and a winding process for a cutting line, wherein the winding device includes: a driving mechanism; a hoisting and winding tool 100, which is used to sleeve the hoisted winding drum 200 on the driving shaft of the driving mechanism for winding; wherein the hoisting and winding tool 100 includes: a hoisting disk 110; a hoisting component 120, which is arranged on the hoisting disk 110 and is used to clamp the top plate 210 of the winding drum 200; a winding guide 130, which is arranged on the hoisting component 120 and is arranged along the winding drum The winding guide 130 includes a support plate 131, the end of which is slidably mounted on the hoisting assembly 120 and arranged axially along the winding drum; a U-shaped rubber strip 132, which is connected to the hoisting assembly 120 via a telescopic block 133; one side of the U-shaped rubber strip 132 is slidably mounted on the support plate 131, and the other side is arranged toward the winding drum; when the cutting line passes through the U-shaped rubber strip 132 and is wound onto the winding drum, it reciprocates along the U-shaped rubber strip 132 to adjust the tension of the cutting line during winding. Through the linkage design of the U-shaped rubber strip 132 and the telescopic block 133, the elastic deformation of the rubber material and the sliding displacement of the telescopic block 133 during the winding process of the cutting line compensate for fluctuations in the cutting line tension in real time. When the cutting line moves to the end of the U-shaped rubber strip 132, the bending rebound force of the rubber strip and the downward sliding of the telescopic block 133 form a dynamic balance, effectively avoiding the problem of excessive tensioning and breakage of the cutting line or loose accumulation caused by the response delay of traditional rigid tensioning mechanisms.
