Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel production technology, specifically a monocrystalline silicon slicing device for photovoltaic panel production. Background Technology

[0002] Monocrystalline silicon, as a crucial component of high-efficiency photovoltaic materials, plays an indispensable role in modern renewable energy systems. Its processing involves slicing monocrystalline silicon rods into thin wafers, which are then used to manufacture high-efficiency solar panels. The quality of the monocrystalline silicon wafers directly impacts the performance of the final photovoltaic modules. Therefore, developing a monocrystalline silicon wafer slicing device that can guarantee high-quality wafers while improving production efficiency is of great significance.

[0003] A search revealed a single-crystal silicon wafer slicing device disclosed in application number 202223290366.6. This device includes a worktable and a single-crystal silicon rod. A fixed base is located on the top of the worktable, and a positioning plate is located within the fixed base. A threaded rod is connected to the top of the positioning plate via a bearing. One end of the threaded rod passes through the top of the fixed base and connects to an external rotating plate. A mounting plate is located on the right side of the top of the worktable, and a hydraulic rod is located on the top of the mounting plate. One end of the hydraulic rod is connected to a cutter. An adjustment mechanism is located within the mounting plate. This device, through the cooperation of the rotating plate, lead screw, and slide rod, can adjust the position of the adjustment plate, thereby adjusting the distance between the adjustment plate and the cutter, and consequently adjusting the slicing thickness. This allows the slicing device to cut single-crystal silicon wafers of different thicknesses.

[0004] However, the traditional slicing method has some shortcomings in actual operation. In particular, during continuous slicing, the position adjustment of the monocrystalline silicon rod depends on manual operation, which not only increases the complexity of operation, but also the frequent manual intervention can easily lead to a decrease in accuracy and affect product quality. In addition, since the position of the monocrystalline silicon rod needs to be recalibrated after each slice, the whole process takes a long time and seriously restricts production efficiency.

[0005] Therefore, with the growing demand for high-efficiency production and high-precision products in the photovoltaic market, existing slicing equipment can no longer meet the industry's development requirements. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.

[0021] Please see Figures 1-4In this embodiment of the present invention, a monocrystalline silicon slicing device for photovoltaic panel production includes a base 1.

A through hole corresponding to the piston end of the clamping cylinder 202 is provided at the middle of the top of the mounting frame 2, so as not to interfere with the extension and retraction of the piston end of the clamping cylinder 202. The bottom of both sides of the mounting frame 2 is provided with a clamping seat 208, and a transmission gear 205 that meshes with the transmission gear plate 203 is provided above the clamping seat 208. The extension and retraction of the piston end of the clamping cylinder 202 drives the transmission gear plate 203 to move. Under the meshing cooperation of the transmission gear plate 203 and the transmission gear 205, the clamping seat 208 is rotated to clamp the monocrystalline silicon rod. The top of the base 1 is provided with a slicing component to slice the clamped monocrystalline silicon rod.

[0022] In this embodiment, the displacement mechanism includes a servo motor 104. The top of the base 1 is provided with a mounting groove 101. A feeding screw 102 is rotatably mounted inside the mounting groove 101. The servo motor 104 is used to drive the feeding screw 102 to rotate. A connecting frame 106 that is slidably connected to the mounting groove 101 is fixedly provided on one side of the feeding seat 105. The bottom of the connecting frame 106 is threadedly connected to the feeding screw 102. A screw nut that is threadedly connected to the feeding screw 102 is fixedly provided at the bottom of the connecting frame 106. A guide groove is provided at the bottom of the support base 107 to avoid interfering with the movement of the connecting frame 106 and to drive the feeding seat 105 to move when the feeding screw 102 rotates.

[0023] In this embodiment, a motor frame 103 is fixedly provided at one end of the base 1, and a servo motor 104 is fixedly provided on one side of the motor frame 103. The transmission shaft of the servo motor 104 is connected to one end of the feeding screw 102. Each time the servo motor 104 is started, its transmission shaft rotates a certain number of times. When the transmission shaft of the servo motor 104 rotates, it drives the feeding screw 102 to rotate, thereby driving the connecting frame 106 to move, and then pushing the feeding seat 105 to move, pushing the single crystal silicon rod placed on the support seat 107 to move forward.

[0024] In this embodiment, a collection groove 108 is provided at the top of the base 1 near the slicing component to collect the cut monocrystalline silicon slices. The other end of the base 1 is provided with a feeding groove 109 that communicates with the collection groove 108. The feeding groove 109 is set in an inclined shape so that the monocrystalline silicon slices that fall into the collection groove 108 can be quickly discharged through the feeding groove 109.

[0025] In this embodiment, the linkage mechanism includes a first connecting arm 204 and a second connecting arm 206. The bottom of both sides of the mounting frame 2 are rotatably provided with the first connecting arm 204 and the second connecting arm 206.

The transmission gear 205 is fixedly provided on the top of the first connecting arm 204. When the piston end of the clamping cylinder 202 extends and retracts, it drives the transmission gear plate 203 to move. Under the meshing action of the transmission gear plate 203 and the transmission gear 205, as well as the action of the first connecting arm 204 and the second connecting arm 206, the clamp 208 is driven to rotate, thereby clamping or separating the single crystal silicon rod.

[0026] In this embodiment, the slicing component includes a mounting plate 3 and a cutting blade 304. The mounting plate 3 is fixedly disposed at the other end of the base 1. A slicing cylinder 301 is fixedly disposed at the top of the mounting plate 3. A motor frame 302 is fixedly disposed at the piston end of the slicing cylinder 301. A slicing motor 303 is fixedly disposed on one side of the motor frame 302. The middle part of the cutting blade 304 is connected to the drive shaft of the slicing motor 303. The slicing blade 304 is driven to rotate rapidly by the rotation of the drive shaft of the slicing motor 303. The rotating cutting blade 304 is driven to move downward by the extension end of the slicing cylinder 301, thereby rapidly cutting the clamped monocrystalline silicon rod to form monocrystalline silicon slices.

[0027] In this embodiment, the drive column of the slicing motor 303 is fixedly provided with a mounting plate, and the mounting plate is connected to the middle of the cutting blade 304 by mounting bolts, so that the cutting blade 304 is set as a detachable structure, thereby allowing the cutting blade 304 to be quickly assembled and disassembled.

[0028] In use, the monocrystalline silicon rod to be sliced ​​is first placed on the support base 107, so that the end of the monocrystalline silicon rod is in contact with the side of the feeding base 105. Then, the servo motor 104 is started. The drive shaft of the servo motor 104 rotates, which drives the feeding screw 102 to rotate, thereby driving the connecting frame 106 to move, which in turn pushes the feeding base 105 to move, pushing the monocrystalline silicon rod placed on the support base 107 forward, so that the end of the monocrystalline silicon rod extends out of the two clamps 208. The piston end of the clamping cylinder 202 is controlled to extend, driving the transmission gear plate 203 to move downward. The transmission gear plate 203 meshes with the transmission gear 205. Under the action of connecting arm 1 204 and connecting arm 206, the clamp 208 is driven to rotate, clamping the monocrystalline silicon rod. Then, the slicing motor 303 is started. The drive shaft of the slicing motor 303 drives the cutting blade 304 to rotate rapidly. The extension end of the slicing cylinder 301 extends the rotating cutting blade 304 downward, thereby quickly cutting the waste material at the end of the clamped monocrystalline silicon rod. Then, the above steps are repeated. Each time the servo motor 104 is started, its drive shaft rotates a certain number of times, so that the moving distance of the monocrystalline silicon rod is constant, making the slices of the monocrystalline silicon rod uniform in thickness and ensuring the slicing quality of the monocrystalline silicon rod.
