TECHNICAL FIELD

[0001] The utility model relates to a swing mechanism, in particular to a double material table swing mechanism for multi-wire cutting machine in the field of multi-wire cutting machine. BACKGROUND

[0002] Multi-wire cutting is a new type of cutting processing method that cuts hard and brittle materials such as semiconductors into hundreds of thin slices at one time by bringing abrasive into the semiconductor processing area for grinding through the high-speed reciprocating movement of the metal wire. The numerical control multi-wire cutting machine has gradually replaced the traditional inner circle cutting and become the main way of silicon wafer cutting processing.

[0003] Traditional multi-wire cutting machines are mostly not swinging, only moving downward, and the cutting wire moves continuously at high speed in the left and right directions, bringing abrasive to the cutting surface of the cutting material for grinding. At this time, the cutting area is large, and the resistance of the cutting surface to the metal wire is also large, which leads to low efficiency and poor cutting surface quality when processing materials with high hardness. In addition, the existing cutting machine can only process single material at a time, which limits the production flexibility. SUMMARY

[0004] In view of the above prior art, the technical problem to be solved by the utility model is that the traditional multi-wire cutting machine is mostly not swinging, which makes the cutting area large and the resistance of the cutting surface to the metal wire large, leading to low efficiency and poor cutting surface quality when processing materials with high hardness.

[0005] To solve the above problems, the utility model provides a double material table swing mechanism for multi-wire cutting machine, which comprises a support seat located below the multi-wire cutting machine, two linear motor sets fixedly connected to the front end of the support seat, an adjusting seat fixedly connected to the front end of the two linear motor sets, an installation seat provided at the upper end of the adjusting seat, two installation rods rotatably penetrating the front end of the installation seat, a positioning plate fixedly connected to the rear ends of the two installation rods, a swing table fixedly sleeved on the outer surface of the installation rod, a placing table fixedly connected to the upper end of the swing table, an installation plate fixedly connected to the front end of the adjusting seat, an installation block and an adjusting motor fixedly connected to the front end of the installation plate respectively, a screw rod fixedly connected to the output end of the adjusting motor, the left end of the screw rod rotatably connected to the right end of the installation block, a sliding block threadedly sleeved on the outer surface of the screw rod, an adjusting plate fixedly connected to the front end of the sliding block, a limiting group one fixedly connected to the rear end of the adjusting plate, a synchronous plate fixedly connected to the rear end of the limiting group one, two swing plates rotatably connected to the rear end of the synchronous plate, and the swing plates are fixedly sleeved on the outer surfaces of the adjacent installation rods.

[0006] In the double-material-table swing mechanism of the multi-wire cutting machine, the swing cutting function and the double-material-plate structure design are introduced to overcome the shortcomings of the traditional multi-wire cutting machine. The swing structure can drive the cutting material to swing within a certain range, so that the multi-wire cutting machine can better adapt to the irregular shape of the material during cutting, thereby reducing stress concentration. The design of the two swing tables can effectively reduce the cutting area of a single material, and the double-station simultaneous cutting can effectively improve the cutting speed of the material, thereby improving the productivity of the multi-wire cutting machine using the swing mechanism.

[0007] As a further improvement of the present application, the front end of the mounting plate is also fixedly connected with a limiting group two, and the limiting group one and the limiting group two each include two limiting rods and a limiting block slidingly sleeved on the outer surface of the limiting rod.

[0008] As a further improvement of the present application, the front end of the limiting block is fixedly connected with the rear end of the adjusting plate, and the two limiting rods in the limiting group one are fixedly connected with the front end of the synchronous plate.

[0009] As a further improvement of the present application, the linear motor group includes a guide rail fixedly connected with the front end of the supporting seat, and the front end of the guide rail is slidingly connected with two linear motor bodies, and the front end of the linear motor body is fixedly connected with the rear end of the adjusting seat.

[0010] As a further improvement of the present application, the lower end of the mounting seat is fixedly connected with a positioning rod, the lower end of the positioning rod is movably penetrated into the adjusting seat, a positioning block is movably sleeved on the outer surface of the positioning rod, and the upper end of the positioning block is fixedly connected with the adjusting seat through a plurality of bolts.

[0011] As a further improvement of the present application, the lower end of the placing table is fixedly connected with two air cylinders, the lower end of the air cylinder is fixedly connected with an L-shaped baffle, and the corresponding ends of the two baffles are respectively in contact with the front and rear ends of the placing table. The upper end of the placing table is fixedly connected with a distance sensor.

[0012] In summary, in actual application, the material can be placed on the placing table. When the multi-wire cutting machine cuts the material, the adjusting motor can be started to drive the screw to rotate. According to the forward and reverse rotation of the screw, the sliding block can be moved left and right, so that the adjusting plate moves left and right. The swing plate connected with the adjusting plate rotates to drive the mounting rod to rotate, so that the swing table slightly swings. At this time, the linear motor body can be started to move upward, driving the adjusting seat to move upward, so that the material moves upward while swinging within a certain range. The multi-wire cutting machine can better adapt to the irregular shape of the material during cutting, and the use of multiple cutting wires can effectively reduce the cutting cross section of the material, improve the cutting efficiency and precision.
