Description

Technical Field

[0001] This utility model relates to the field of multi-wire cutting machine technology, specifically a multi-wire cutting machine with safety protection function. Background Technology

[0002] A multi-wire cutting machine is a device used for cutting hard and brittle materials. Multi-wire cutting uses the high-speed reciprocating motion of metal wires to bring abrasives into the semiconductor processing area for grinding, cutting hard and brittle materials such as semiconductors into hundreds of thin slices at once.

[0003] Multi-wire cutting machines cut hard and brittle materials using metal wires and abrasives, processing the materials into multiple thin sheets. Existing multi-wire cutting machines require manual opening and closing of the protective door to prevent debris from flying out during cutting. This protective method is relatively cumbersome. Furthermore, existing multi-wire cutting machines have a fixed spraying range when spraying cooling liquid, making it difficult to spray the metal wires and materials at the bottom evenly. Utility Model Content

[0004] The purpose of this invention is to provide a multi-wire cutting machine with safety protection function to solve the problem mentioned in the background art that existing multi-wire cutting machines are not convenient for protection.

A drive gear is fixedly connected to the outer side of the motor output shaft. A driven gear is meshed with the outer side of the drive gear. A connecting rod b is provided at the bottom of the driven gear. A spraying pipe is fixedly connected to one end of the connecting rod b.

[0007] Preferably, a connecting rod a is fixedly connected to the bottom of the workbench, a connecting plate a is fixedly connected to one side of the bottom of the connecting rod a, the outer side of the connecting plate a is slidably connected to the machine body, and a protrusion is fixedly connected to one side of the connecting plate a.

[0008] Preferably, one end of the protrusion is hemispherical, the outer side of the protrusion is slidably connected to the connecting shaft, and a toggle block a is fixedly connected to one side of the driven gear.

[0009] Preferably, a connecting plate b is slidably connected to the outer side of the actuating block a, a crossbar is fixedly connected to one side of the connecting plate b, and actuating blocks b are fixedly connected to both ends of the crossbar. One side of the driven gear is movably connected to the machine body through a rotating shaft.

[0010] Preferably, the actuating block b is cylindrical in shape, and a vertical rod is slidably connected to the outer side of the actuating block b.

[0013] Compared with existing technologies, the beneficial effects of this multi-wire cutting machine with safety protection function are as follows: When using this multi-wire cutting machine with safety protection function, the material is fixed to the worktable, and then the hydraulic cylinder is activated to drive the worktable to move upward. When the worktable moves, it will also drive the connecting rod A and the protrusion in the bottom protection mechanism to move. The protrusion will slide in the connecting shaft, thereby causing the connecting shaft to rotate. When the connecting shaft rotates, it can also drive the top protective door to rotate, so that the protective door closes. At this time, the protrusion will enter the straight groove of the connecting shaft. At this time, the protective door will not rotate, but the connecting rod A can still move upward with the worktable, thereby driving the material to contact the metal wire wrapped around the outside of the connecting roller, completing the cutting of the material. In this way, the multi-wire cutting machine can be automatically protected through the above operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-7 This utility model provides a technical solution: a multi-wire cutting machine with safety protection function, comprising: a machine body 1 and a protective mechanism 5. Multiple sets of connecting rollers 2 are arranged on one side of the machine body 1, and multiple sets of cutting wires are sleeved on the outer sides of each set of connecting rollers 2. A hydraulic cylinder 3 is installed at the bottom of the machine body 1, and a worktable 4 is fixedly connected to the top of the hydraulic cylinder 3.

[0024] A protective mechanism 5 is provided on one side of the body 1. The protective mechanism 5 includes a connecting shaft 504 that is movably connected to the body 1 via a bearing. The outer side of the connecting shaft 504 is provided with a spiral groove 505 and a straight groove 507. A protective door 506 is fixedly connected to the top of the connecting shaft 504. A spraying mechanism 6 for spraying cooling liquid is provided inside the body 1. The spraying mechanism 6 includes a motor 601 that is fixedly connected to the inside of the body 1. A drive gear 602 is fixedly connected to the outer side of the output shaft of the motor 601. A driven gear 603 is meshed with the outer side of the drive gear 602. A connecting rod b609 is provided at the bottom of the driven gear 603. A spraying pipe 610 is fixedly connected to one end of the connecting rod b609.

[0025] A connecting rod a501 is fixedly connected to the bottom of the workbench 4. A connecting plate a502 is fixedly connected to one side of the bottom of the connecting rod a501. The outer side of the connecting plate a502 is slidably connected to the machine body 1. A protrusion 503 is fixedly connected to one side of the connecting plate a502. One end of the protrusion 503 is hemispherical. The outer side of the protrusion 503 is slidably connected to the connecting shaft 504. A toggle block a604 is fixedly connected to one side of the driven gear 603. A connecting plate b605 is slidably connected to the outer side of the toggle block a604. A crossbar 606 is fixedly connected to one side of the connecting plate b605. Toggle blocks b607 are fixedly connected to both ends of the crossbar 606. The driven gear 603 is connected to one side via a rotating shaft. The actuating block b607 is cylindrical in shape, and a vertical rod 608 is slidably connected to the outer side of the actuating block b607. The bottom of the vertical rod 608 is fixedly connected to the connecting rod b609, and the outer side of the connecting rod b609 is movably connected to the body 1 through a bearing. One end of the connecting rod b609 is connected to a pressure pump 612 through a hose. A limit rod 611 is slidably connected inside the crossbar 606. Both ends of the limit rod 611 are fixedly connected to the body 1. A sliding groove matching the actuating block a604 is opened inside the connecting plate b605. The sliding groove and the actuating block a604 form a sliding structure. The driving gear 602 and the driven gear 603 form a meshing transmission structure.

[0026] In practical implementation, this multi-wire cutting machine with safety protection function is used by fixing the material onto the worktable 4, and then starting the hydraulic cylinder 3 to move the worktable 4 upward. When the worktable 4 moves, it will also move the connecting rod a501 in the bottom protection mechanism 5, so that the protrusion 503 on the connecting plate a502 on the bottom side of the connecting rod a501 will also move upward. When the protrusion 503 moves, it will slide in the spiral groove 505 in the connecting shaft 504, thereby causing the connecting shaft 504 to rotate. When the connecting shaft 504 rotates, it can also drive the top protective door 506 to rotate, so that the protective door 506 closes. At this time, the protrusion 503 will enter the straight groove 507 of the connecting shaft 504, so the protective door 506 will not rotate, but the connecting rod a501 can still move upward with the worktable 4, thereby driving the material to contact the metal wire wrapped around the outside of the connecting roller 2 to complete the cutting of the material. When the cutting is completed, the hydraulic cylinder 3 will drive the worktable 4 to reset, and the protective door 506 will also open.

[0027] When the motor 601 drives the connecting roller 2 to rotate, it will also drive the drive gear 602 in the spraying mechanism 6 to rotate and mesh with the driven gear 603. When the driven gear 603 rotates, it can slide in the groove of the connecting plate b605 through the actuating block a604 on one side, thereby actuating the connecting plate b605 to move back and forth. The crossbar 606 on one side of the connecting plate b605 will also move and slide outside the limit rod 611. The actuating block b607 on one side of the crossbar 606 will slide in the strip groove inside the vertical rod 608, thereby actuating the vertical rod 608 and the connecting rod b609 to rotate. When the connecting rod b609 rotates, it can drive the spraying pipe 610 to swing and spray, so that the cooling liquid is evenly in contact with the metal wire and material at the bottom. In this way, the above operation can facilitate automatic protection of the multi-wire cutting machine.

[0028] In summary: When using a multi-wire cutting machine with safety protection functions, first fix the material to be cut onto the worktable 4, then start the motor 601 to drive the connecting roller 2 to rotate, so that the multiple sets of metal wires wound on the connecting roller 2 move. When the material comes into contact with the high-speed moving metal wires, it can be cut. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.
