Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic technology, and relates to a wafer slicing device for separating silicon wafers. Background Technology

[0002] In the photovoltaic industry, the stable separation of silicon wafers after debinding is a crucial step in ensuring wafer quality and production efficiency. Current technologies have many shortcomings in achieving stable wafer separation. Currently, silicon wafer slicing faces numerous challenges. On the one hand, traditional slicing processes often require significant manpower and time, increasing production costs and leading to quality instability. For example, manual slicing, with wafers only 0.1-0.2mm thick, is thin and brittle, making it highly susceptible to breakage during manual handling, resulting in a high fragmentation rate and making precise quality control difficult. With continuously rising labor costs, the cost disadvantage of this method becomes increasingly apparent. Furthermore, its high labor intensity is detrimental to long-term stable production. Moreover, the work cycle is long, preventing continuous operation of the entire production line. If mechanical clamping separation is used, the wafer thickness is typically between 0.1-0.2mm, making it brittle and fragile. Uneven pressure or clamping position deviations during clamping can easily cause cracks, damage, or even complete shattering. This not only wastes raw materials but also often results in the inability to separate silicon wafers. Production lines also need to be shut down for maintenance. The precision of separation is also a major challenge for current technology. Silicon wafers may be tightly adhered to each other, making stable separation difficult with existing technology, leading to incomplete separation. Utility Model Content

The bottom water spray component B and the upper water spray block in the slitting mechanism are opened, and the water pump sprays water at a set pressure onto the silicon wafers. The silicon wafers are separated under the pressure of the water spray. At the same time, the upper cylinder drives the slitting line or slitting plate to separate the separated silicon wafers, preventing the silicon wafers from sticking together and separating the silicon wafers that need to be separated from the remaining silicon wafers. The water spraying and the cylinder are synchronized to achieve stable separation of the silicon wafers.

[0165] In practical use, the wafer slitting device for separating silicon wafers is arranged entirely within the tank 1 of a water tank. The wafer retrieval process takes place in water. A manual crane or an automatic gantry robot (both existing equipment, unrelated to the structure of this utility model, and not described in detail; their function is sufficient) removes the debonded wafer-containing debonding frame (existing technology) from the water tanker (existing equipment) and places it onto the conveyor belt A301 of the receiving and conveying mechanism 3. The wafer pressing device presses the wafers down from above, the debonding frame bottom rod automatically opens, and the debonding frame is lifted (this part is not described in this utility model's technical solution). The synchronous belt B of the wafer side clamping and centering mechanism 2, made of sponge material, clamps the wafers and conveys them forward. The silicon wafers are transported to the slicing position of the slicing mechanism 4. The bottom water spray component B and the upper water spray block A are opened. The water pump sets the pressure to spray water onto the silicon wafers. The silicon wafers are separated under the pressure of the water spray. At this time, the upper cylinder 40101 drives the slicing component 40104 to separate the separated silicon wafers and prevent the front and rear silicon wafers from sticking together. The receiving conveyor mechanism 3 and the silicon wafer side clamping centering mechanism 2 stop rotating, while the separating conveyor mechanism 6 and the slab-separating side clamping centering mechanism 5 operate to transport the separated silicon wafers to the next process. Specifically, when the silicon wafer side clamping centering mechanism 2 is working: the side clamping centering transmission group A and the side clamping centering transmission group B start working simultaneously. The side clamping drive motors on the two centering components start working, driving the side clamping drive wheel 216, which in turn drives the side clamping driven wheel 215 to move via the synchronous belt A203. This causes the synchronous belt A203 to drive the synchronous belt transmission block to move. The linear guide rail and slider on the guide component then drive the support frame to slide on the fixed base plate. This allows the two centering components to drive the two support frames on the same side to move, which in turn drives the horizontal plate 206 at the bottom of the support frame to move, causing the two parallel synchronous belts B205 to begin moving towards or away from each other. This achieves stable workpiece clamping on the conveyor belt A301. Simultaneously, side clamping assemblies A and B also begin to operate. The clamping and conveying motor 208 drives the transmission rod A210, which in turn drives the drive wheel 211 to rotate. This, in turn, drives the synchronous belt B205 to move with the help of the driven wheel A408, thus achieving stable clamping and conveying of several silicon wafers by the silicon wafer side clamping centering mechanism 2, without the need for other fixing equipment. The nylon limiting plates A and 214 and the metal pad A213 ensure stable operation of the synchronous belt B205 in water without scratching the workpieces. The operating time is also stable, resulting in low maintenance and minimal wear.

[0166] When the receiving and conveying mechanism 3 is in operation: several silicon wafers are placed onto the conveyor belt A301 of the receiving and conveying mechanism 3 after the previous process. The conveyor motor A302 works, and then power is transmitted through the synchronous belt C310, the synchronous driven wheel, the drive shaft B305, and the conveyor wheel of the conveyor belt A301. With the cooperation of the conveyor driven wheel A, the conveyor belt A301 is moved to transfer the workpiece. Simultaneously, the conveyor motor A302 works, and then power is transmitted through the synchronous belt C310, the synchronous driven wheel, the drive shaft A304, and the conveyor drive wheel 313 of the conveyor belt B303. With the cooperation of the conveyor driven wheel B316, the conveyor belt B303 is moved to transfer the workpiece, achieving stable synchronous transportation. In this way, the conveyor belt A301 stably transports the workpiece onto the two conveyor belts B303.

[0167] In operation, the wafer slicing mechanism 4 works as follows: At the slicing position of the wafer slicing mechanism 4, the bottom water spray assembly B402 and the upper water spray block A40107 open. Water at a set pressure from the water pump sprays water onto the silicon wafers, causing them to separate under water pressure. At this time, the upper cylinder 40101 drives the wafer slicing component 40104 to separate the wafers, preventing them from sticking together. Due to the specific positioning and structure of the water spray assembly B402 combined with the positioning of the wafer slicing component 40104, stable separation of the silicon wafers is achieved. This results in stable wafer separation, stable operation, and a low failure rate.

[0168] In operation, the segmented side clamping centering mechanism 5 works as follows: The segmented side clamping drive motor 502 on the centering drive assembly starts working. The segmented side clamping drive motor 502 drives the segmented side clamping drive wheel 504 to transmit power, which is then transmitted to the segmented side clamping driven wheel 505 through the synchronous belt E503, thus moving the synchronous belt E503. The synchronous belt E503 is engaged with the synchronous belt transmission block, thereby moving the two support frames. In turn, the vertical rod 517 at the bottom of the support frame drives the two fixed frame plates to move, thus causing the two parallel side clamping conveyor belts 512 to move towards each other or away from each other. This achieves stable movement of the workpiece on the conveyor belt, and the support frame slides through the guide component at the bottom. Simultaneously, the side clamping conveyor assembly also operates synchronously. The conveyor motor B509 drives the transmission rod B510, which in turn drives the side clamping conveyor drive wheel 511 to rotate. This, in turn, drives the side clamping conveyor belt 512, which, in conjunction with the side clamping conveyor driven wheel 515, moves to achieve transmission. This enables the stable clamping and transmission of several silicon wafers after slicing by the slicing side clamping centering mechanism 5, without the need for other fixed equipment. The metal pad C and nylon limiting plate C ensure stable operation of the side clamping conveyor belt 512 in water without scratching the workpiece. The operating time is also stable, resulting in low maintenance and minimal wear.

[0169] In operation, the material distribution and conveying mechanism 6 works as follows: the material distribution and conveying motor 601 starts working, which in turn drives the driving wheel 607 to drive the synchronous belt F602 to drive the driven wheel B609; the driven wheel B609 drives the belt drive wheel 818 through the transmission shaft D603, and the belt drive wheel 818 drives the two driven wheels C612 through the synchronous belt 604 to achieve power transmission, thereby driving the synchronous belt 604 to move and transfer the workpiece, achieving stable and synchronous transportation. The workpiece is then transferred to the next process.
