Description

[0001] The utility model relates to the technical field of solar cell preparation equipment, in particular to a conveying device. Background Art

[0002] With the development of the photovoltaic industry, people's requirements for the production capacity of battery wafers are also getting higher and higher. In current production activities, it is necessary to take out the battery wafers from the flower basket (wafer carrier) one by one and put them into the graphite carrier plate (wafer carrier). The existing technology is that after the flower basket elevator is in place, a telescopic runway is used. The telescopic plate extends, the flower basket elevator descends, and the wafers flow out one by one through the belt. Since the telescopic runway only uses the friction force generated by the contact between the belt and the wafer as the driving force, when the equipment speeds up, there will be a slipping phenomenon between the wafer and the belt, resulting in a beat bottleneck and inaccurate wafer pitch, and it cannot be docked with the subsequent mechanism, causing edge fragments.

[0046] As a conveying device 100 according to a specific embodiment of the present utility model, the conveying device 100 is mainly used to convey the target object of the previous process to the next process. Specifically, the target object in this embodiment may be a silicon wafer. Specifically, the conveying device 100 in this embodiment may include a vacuum conveying mechanism 200 and a rapid conveying mechanism 300. Among them, the vacuum conveying mechanism 200 may include at least one set of conveying belt assemblies 210 and at least one set of vacuum assemblies 220. The target object is adsorbed at the corresponding conveying belt assembly 210 by the vacuum assembly 220, and the conveying belt assembly 210 is used to convey the target object along a preset direction. The rapid conveying mechanism 300 is located on one side of the vacuum conveying mechanism 200 to convey the target object transported from the vacuum conveying mechanism 200 to the next process.

[0047] Specifically, the conveying device 100 in this embodiment includes a vacuum conveying mechanism 200 and a rapid conveying mechanism 300. The target object can be adsorbed at the conveying belt assembly 210 by the vacuum assembly 220 and then conveyed to the rapid conveying mechanism 300. Furthermore, while rapidly conveying the target object, it is possible to avoid the target object slipping on the belt, achieve high-speed and high-precision transmission of the silicon wafer, greatly improve the conveying beat of the battery wafers, and significantly improve the production efficiency.

[0048] Specifically, the conveying device 100 in this embodiment may include a carrier basket assembly 410, a carrier basket conveying assembly 420, and a lifting assembly 430. Among them, the carrier basket assembly 410 is used to carry at least one target object and arrange the target objects in sequence. The carrier basket conveying assembly 420 is connected to the carrier basket assembly 410 and is used to convey the carrier basket assembly 410 from the previous station to the lifting assembly 430. The lifting assembly 430 is used to drive the carrier basket conveying assembly 420 and the carrier basket assembly 410 to lift and lower to adapt to the height of the vacuum conveying mechanism 200, and then the target objects are sequentially output through the vacuum conveying mechanism 200.

[0049] Specifically, the carrier basket assembly 410 may include a plurality of support units 411 for placing the target objects, and each support unit 411 can support one target object. The plurality of support units 411 can be arranged side by side vertically, so that the target objects can be arranged one above the other in sequence. Of course, the support units 411 can be arranged horizontally side by side so that the target objects are arranged side by side in the horizontal direction. And each support unit 411 may include four support pieces, and the upper surfaces of the four support pieces of each support unit 411 are on the same horizontal plane.

[0050] After the flower basket assembly 410 in the previous process, the mechanism of the previous process sequentially sets the silicon wafers at the flower basket assembly 410, and transports the flower basket to the lifting assembly 430 through the flower basket conveying assembly 420. Specifically, the flower basket conveying assembly 420 can be composed of a motor 421, a synchronous pulley 422, and a synchronous belt 423. The motor 421 drives the synchronous pulley 422 to rotate, thereby driving the synchronous belt 423 to move, and then transporting the flower basket assembly 410 placed on the synchronous belt 423 to the lifting assembly 430.

[0051] After the flower basket reaches the lifting assembly 430, the lifting assembly 430 drives the flower basket conveying assembly 420 to move up and down, so as to match the height of the target object with the vacuum conveying mechanism 200, and the target object is output through the vacuum conveying mechanism 200.

Among them, each first synchronous pulley 212 is connected to the first driving mechanism 211 to rotate under the drive of the first driving mechanism 211. Each first belt 213 is sleeved on a corresponding group of first synchronous pulleys 212 to move when the first synchronous pulleys 212 rotate, thereby driving the target object placed above the first belt 213 to move, wherein the extending direction of the first belt 213 is parallel to the preset direction.

[0053] Specifically, the number of the first driving mechanisms 211 and the first synchronous pulleys 212 of each conveying belt assembly 210 corresponds, and the specific number can be designed according to the situation. The number of the first belts 213 can be designed according to the situation. For example, in this embodiment, the conveying belt assembly 210 may include two groups. Each conveying belt assembly 210 includes two first driving mechanisms 211 and two groups of first synchronous pulleys 212, and each first driving mechanism 211 drives one group of first synchronous pulleys 212 to rotate. One, two or more first belts 213 can be designed at each first synchronous pulley 212. There is a gap between two adjacent first belts 213.

[0054] As a specific embodiment of the present utility model, each vacuum assembly 220 of this embodiment may include a vacuum chamber 221, and the vacuum chamber 221 may include at least one vacuum hole 222, and the vacuum hole 222 is located at the side of at least one first belt 213.

[0055] Specifically, if one first belt 213 is designed at each first synchronous pulley 212, the vacuum hole 222 can be designed on one side or both sides of the first belt 213. If multiple first belts 213 are designed at each first synchronous pulley 212, the vacuum hole 222 can be designed at the gap between two adjacent belts.

[0056] Specifically, the vacuum holes 222 of this embodiment are arranged side by side along a preset direction. And the vacuum holes 222 can be formed in a row shape or arranged in an array.

[0057] As a specific embodiment of the present utility model, the vacuum chamber 221 of this embodiment may include a plurality of first air outlet holes 223. Each vacuum assembly 220 may further include a vacuum generator (not shown in the figure) and an air distribution block 224. Wherein, each air distribution block 224 may include a plurality of air inlet holes 225 connected to the first air outlet holes 223 in one-to-one correspondence and a second air outlet hole 226 connected to the vacuum generator, so as to evacuate the vacuum chamber 221 through the air distribution block 224.

[0058] Specifically, a plurality of first air outlet holes 223 are provided at the vacuum chamber 221 of this embodiment, and an air distribution block 224 is provided between the vacuum generator and the vacuum chamber 221. The air inlet holes 225 are provided on the air distribution block 224, and the air inlet holes 225 and the first air outlet holes 223 are in one-to-one correspondence, so that the vacuum degree at different positions of the vacuum chamber 221 is more uniform when evacuating.

[0059] As a specific embodiment of the present utility model, each conveying belt assembly 210 of this embodiment may further include a second driving mechanism 214 and a support member 215. Wherein, the support member 215 is used to support the first synchronous pulley 212 and the vacuum chamber 221, and drive the first synchronous pulley 212 and the vacuum chamber 221 to move together along a preset direction when moving under the drive of the second driving mechanism 214.

[0060] Specifically, the second driving mechanism 214 and the support member 215 of this embodiment mainly drive the first synchronous pulley 212 and the vacuum chamber 221 to move along a preset direction, and then lift the first synchronous pulley 212 and the vacuum chamber 221 to the flower basket assembly 410 through the second driving mechanism 214. After taking down the target object at the flower basket assembly 410, the target object is then transported away from the flower basket assembly 410 by using the first synchronous belt.

[0061] Specifically, in this embodiment, the target object is taken down from the flower basket assembly 410 through the first synchronous pulley 212, the first belt 213 and the vacuum chamber 221. The vacuum chamber 221 can give a certain suction force to the target object. On the one hand, it is convenient to take down the target object, and on the other hand, it also increases the friction between the target object and the first belt 213, avoiding the target object from sliding at the first belt 213 and causing the subsequent mechanism to be unable to dock, resulting in edge fragments.

[0062] More specifically, since the objects at the flower basket are stacked, the first synchronous pulley 212 and the first belt 213 extract from the object at the bottom of the flower basket assembly 410. After each extraction, the lifting assembly 430 of the flower basket assembly 410 drives the flower basket assembly 410 to move downward to match the height of the first belt 213. Then, the first belt 213 is extended under the object by the second driving mechanism 214, and the object is sucked and output. Repeat this step until all the objects in the flower basket assembly 410 are transported out. Then, the flower basket assembly 410 reaches the previous process under the drive of the flower basket conveying assembly 420, and then objects are placed into the flower basket assembly 410.

[0063] As a specific embodiment of the present utility model, the fast conveying mechanism 300 of this embodiment may include a third driving mechanism 310, a second synchronous pulley 320, and a second belt 330. The second synchronous pulley 320 rotates under the drive of the third driving mechanism 310. The second belt 330 is sleeved at the second synchronous pulley 320 and moves when the second synchronous pulley 320 rotates.

[0064] Specifically, after the object of this embodiment is removed from the flower basket assembly 410 by the conveying belt assembly 210 of the object, it will be transported to the fast conveying mechanism 300, and then the fast conveying mechanism 300 transports the object to the next process.

[0065] Specifically, a plurality of placing units 340 for placing objects are provided at the second belt 330 of this embodiment, and each placing unit 340 may include a positioning member 350 to position each object transported to the placing unit 340.

[0066] Specifically, the object placed at the fast conveying mechanism 300 can be positioned through positioning in this embodiment, so as to realize the high-speed and high-precision transmission of the object.

[0067] As a specific embodiment of the present utility model, the positioning member 350 of this embodiment may include a first stop block 351 and a second stop block 352 arranged along the moving direction of the second belt 330, and a third stop block 353 and a fourth stop block 354 arranged along the direction perpendicular to the belt movement, so as to position the object through the first stop block 351, the second stop block 352, the third stop block 353, and the fourth stop block 354. Specifically, one or more stop blocks are provided at one side of each object, so each positioning member 350 includes at least four stop blocks. Of course, the stop blocks of different positioning members 350 can overlap. For example, the stop block behind the previous object can be the stop block in front of the next object. The object can be positioned at a certain position through the stop blocks, and the sliding of the object during movement can also be avoided.

[0068] Specifically, in this embodiment, the vacuum conveying mechanism 200 and the rapid conveying mechanism 300 are combined and used together, which can achieve the high-speed and high-precision transmission of the target object, greatly improve the conveying beat of the target object, and significantly improve the production efficiency. Through tests, the combined use of the vacuum conveying mechanism 200 and the rapid conveying mechanism 300 in this embodiment has increased the transmission beat from 1 s to 0.6 s.
