Description

Technical Field

[0001] This utility model relates to the field of processing and cutting devices, and in particular to a wire-laying device for silicon wafer cutting. Background Technology

[0002] Silicon wafers are cut using steel wires, which need to be wired to meet the requirements of silicon wafer cutting.

[0003] The steel wire used for silicon wafer dicing needs to be wound by a winding roller. This involves releasing the wire from the winding roller onto a pulley. However, conventional wire release winding rollers simply wrap the wire around their surface without providing any restraint. As a result, when releasing the wire from the winding roller, the lack of restraint on one side makes it easy for the remaining wire to loosen and overlap, preventing proper wire release. Therefore, a wire feeding device for silicon wafer dicing is needed to protect the wire release winding roller and prevent the wire from loosening, overlapping, or misaligning. Utility Model Content

[0004] The purpose of this invention is to overcome the defect that conventional winding rollers cannot limit the wire feeding side and to provide a wire feeding device for silicon wafer cutting.

[0005] The technical solution to achieve the above objective is: a wire feeding device for silicon wafer cutting, including a winding roller, an adjustment mechanism on the winding roller, a limit mechanism installed on the adjustment mechanism, and a protective mechanism on the winding roller;

[0006] The limiting mechanism includes sliding holes, support rods, springs, pressure rings, and extension grooves. Support rods are slidably connected to the side walls of the two sliding holes. One end of the support rod is connected to the pressure ring. The middle side wall of the winding roller passes through the inner opening of the pressure ring. One end of the spring is connected to the side wall of the pressure ring. Two symmetrically distributed extension grooves are formed on the inner side wall of the winding roller.

[0007] Preferably, the diameter of the extension groove is larger than that of the support rod, and the support rod is aligned with the extension groove.

[0008] Preferably, the adjusting mechanism includes an adjusting screw hole, an adjusting screw, a rotating rod, a circular hole, a guide rod, a connecting ring, and a rotating hole. An adjusting screw hole is provided on one side wall of the winding roller, and an adjusting screw is threaded into the adjusting screw hole. One end of the adjusting screw is connected to a rotating rod. A rotating hole is provided on the side wall of the connecting ring, and the side wall of the rotating hole is rotatably connected to the rotating rod. A circular hole is provided on the side wall of the winding roller, and a guide rod is movably connected within the circular hole. One end of the guide rod is connected to a connecting ring.

[0009] Preferably, the middle sidewall of the winding roller passes through a series of inner openings.

[0010] Preferably, the rotating rod is I-shaped.

[0011] Preferably, the other end of the spring is connected to the side wall of the ring, and the side wall of the ring has two symmetrically distributed sliding holes.

[0012] Preferably, the protective mechanism includes a connecting rod, a support block, a limiting screw hole, a limiting screw rod, and a pressure block. Both ends of the connecting rod are connected to the support block. One of the support blocks has a limiting screw hole on its side wall. The limiting screw hole is internally threaded with a limiting screw rod. One end of the limiting screw rod is connected to the pressure block.

[0013] Preferably, the pressure block is located between two support blocks, and the bottom end of the connecting rod is set as an arc surface, the diameter of which is equal to the diameter of the outer wall of the winding roller.

[0014] The beneficial effects of this utility model are:

[0015] 1) The adjustment mechanism is used to adjust the distance between the pressure ring and one side wall of the winding roller, so that the wire feeding end is pressed against the pressure ring, and the pressure ring squeezes the spring, so that the wound wire can stick together tightly. This avoids the wire from loosening towards the feeding end and mixing and overlapping together, which would cause the wire to become entangled. This ensures that the wire can be fed normally. When the wire is fed, the number of turns of the wire is reduced, and the spring will rely on its own elasticity to continuously press the pressure ring against the wire, so that the wire feeding end can be continuously blocked and limited during the wire feeding process.

[0016] 2) Place the connecting rod on the outer arc surface of the winding roller, and place the winding roller inside the two support blocks. Place the other support block against one end surface of the winding roller. Then, rotate the limiting screw so that the pressure block can press against the other end surface of the winding roller, thereby fixing the protective mechanism on the surface of the winding roller. By setting multiple protective mechanisms, the outside of the winding roller is wrapped, leaving only an opening for easy wire release. When the steel wire inside the winding roller breaks, the steel wire will be blocked by the connecting rod, thereby achieving the effect of providing protection. Attached Figure Description

[0025] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Reference Appendix Figure 1-6 A wire feeding device for silicon wafer cutting includes a winding roller 1, an adjustment mechanism 2 is provided on the winding roller 1, a limit mechanism 3 is installed on the adjustment mechanism 2, and a protective mechanism 4 is provided on the winding roller 1.

[0028] The limiting mechanism 3 includes a sliding hole 301, a support rod 302, a spring 303, a pressure ring 304, and an extension groove 305. The support rod 302 is slidably connected to the side walls of the two sliding holes 301. One end of the support rod 302 is connected to the pressure ring 304. The middle side wall of the winding roller 1 passes through the inner opening of the pressure ring 304. One end of the spring 303 is connected to the side wall of the pressure ring 304. Two symmetrically distributed extension grooves 305 are opened on the inner side wall of the winding roller 1. The diameter of the extension grooves 305 is larger than that of the support rod 302. The support rod 302 is aligned with the extension grooves 305. The other end of the spring 303 is connected to the side wall of the connecting ring 206. Two symmetrically distributed sliding holes 301 are opened on the side wall of the connecting ring 206. The extension grooves 305 provide space for the movement of the support rod 302.

[0029] A steel wire is wound onto the winding roller 1, with the closed end of the wire against the other side wall of the winding roller 1. The unwinding end of the wire is close to one side wall of the winding roller 1. The distance between the pressure ring 304 and one side wall of the winding roller 1 is adjusted using the adjusting mechanism 2, so that the unwinding end of the wire is pressed against the pressure ring 304, causing the pressure ring 304 to compress the spring 303. This ensures that the wound steel wire is tightly attached together, preventing the steel wire from loosening towards the unwinding end and causing it to mix and overlap, thus preventing the steel wire from becoming entangled. This ensures that the steel wire can be unwound normally. Furthermore, during unwinding, the number of turns of the steel wire decreases, and the spring 303 will use its own elasticity to continuously press the pressure ring 304 against the steel wire, ensuring that the unwinding end of the steel wire is continuously blocked and limited during the unwinding process.

[0030] Reference Appendix Figure 1-5 The adjusting mechanism 2 includes an adjusting screw hole 201, an adjusting screw 202, a rotating rod 203, a round hole 204, a guide rod 205, a connecting ring 206, and a rotating hole 207. The adjusting screw hole 201 is provided on one side wall of the winding roller 1. The adjusting screw 202 is internally threaded into the adjusting screw hole 201. One end of the adjusting screw 202 is connected to the rotating rod 203, which is I-shaped. The rotating hole 207 is provided on the side wall of the connecting ring 206. The side wall of the rotating hole 207 is rotatably connected to the rotating rod 203. The round hole 204 is provided on the side wall of the winding roller 1. The guide rod 205 is movably connected inside the round hole 204. One end of the guide rod 205 is connected to the connecting ring 206. The middle side wall of the winding roller 1 passes through the inner opening of the connecting ring 206.

[0031] Rotating the adjusting screw 202 causes the adjusting screw 202 to drive the rotating rod 203 to move. Since the rotating rod 203 is I-shaped and the connecting ring 206 is located in the groove of the rotating rod 203, the rotating rod 203 can push the connecting ring 206 to move. The connecting ring 206 drives the spring 303 and the support rod 302 to move, thereby causing the spring 303 and the support rod 302 to drive the pressure ring 304 to move, thus achieving the effect of adjusting the distance between the pressure ring 304 and the side wall of the winding roller 1.

[0032] Reference Appendix Figure 1-2 and attached Figure 6 The protective mechanism 4 includes a connecting rod 401, a support block 402, a limiting screw hole 403, a limiting screw 404, and a pressure block 405. Both ends of the connecting rod 401 are connected to the support block 402. One of the support blocks 402 has a limiting screw hole 403 on its side wall. The limiting screw hole 403 is internally threaded to the limiting screw 404. One end of the limiting screw 404 is connected to the pressure block 405. The pressure block 405 is located between the two support blocks 402. The bottom end of the connecting rod 401 is set as an arc surface. The diameter of the arc surface is equal to the diameter of the outer side wall of the winding roller 1.

[0033] Place the connecting rod 401 on the outer arc surface of the winding roller 1, and place the winding roller 1 inside the two support blocks 402. Place another support block 402 against one end surface of the winding roller 1. Then, rotate the limiting screw 404 so that the pressure block 405 can press against the other end surface of the winding roller 1, thereby fixing the protective mechanism 4 on the surface of the winding roller 1. By setting multiple protective mechanisms 4, the outer side of the winding roller 1 is wrapped, leaving only an opening for easy wire release. When the steel wire inside the winding roller 1 breaks, the steel wire will be blocked by the connecting rod 401, thereby achieving the effect of providing protection.
