Description

Technical Field

[0001] This invention belongs to the field of solar panel manufacturing technology, specifically a solar cell wire mesh feeding and clamping mechanism. Background Technology

The feeding machine has a feeding plate and an opening. Near the feeding plate, a support unit for stacking the solar silicon wafers is provided. The support unit includes several pressure substrates. A groove is provided near the pressure substrates on the feeding machine, and the pressure substrates are slidably connected within the groove. An air blowing component is provided inside the feeding machine to blow air between the solar silicon wafers. This device aims to stack the solar silicon wafers, setting a spacer layer between each wafer to prevent adhesion between them. It also treats dust on the surface of the wafers non-destructively, improving screen printing efficiency.

[0004] In current technology, before processing solar cells, the wire mesh needs to be cleaned. After cleaning, the wire mesh is transported by a conveyor. During the transport process, the wire mesh is not placed in a uniform manner, which can easily cause jams during the feeding process, affecting the smoothness of feeding and reducing work efficiency. Summary of the Invention

[0005] Purpose of the invention: In order to overcome the shortcomings of the existing technology and solve the problem that the placement of the wire mesh is not uniform during the conveying process, and that it is easy to get stuck during the feeding process, which affects the smooth feeding, a wire mesh feeding clamping mechanism for solar cells is proposed. The clamping structure can realize the correction of the wire mesh during the feeding process, so as to ensure that the wire mesh does not get stuck.

[0006] Technical solution: To achieve the above objectives, the technical solution adopted by this invention is as follows: A solar cell wire mesh feeding and clamping mechanism includes a base plate, a mounting frame, a conveying assembly, an extension assembly, and a correction assembly. The mounting frame is mounted on the base plate, and the conveying assembly is mounted on the mounting frame. The conveying assembly is used to convey the extension assembly, and the extension assembly is used to receive and convey the wire mesh. The correction assembly is used to correct the wire mesh during the conveying process of the extension assembly.

[0008] The correction platform is fixedly connected to the mounting frame. The driving wheel and driven wheel are rotatably mounted on the correction platform via bearings. The driving wheel and driven wheel are connected by a transmission belt, which has first and second rubber teeth.

One end of the second actuating plate is fixedly connected to the second actuating rod via a second connecting piece, and the other end of the second actuating plate is fixedly connected to the second roller bracket. The motor is mounted on the correction platform and is connected to the drive shaft.

[0009] Preferably: when the first rubber tooth moves to the first limit position one, the second rubber tooth is located at the first limit position two. At this time, the first rubber tooth separates from the first actuating rod, the second rubber tooth separates from the second actuating rod, the spring resets, and the first roller bracket and the second roller bracket approach each other until they reach the limit position under the action of the spring reset. At this time, the first actuating rod is located at the first limit position three, the second actuating rod is located at the first limit position four, and the first correction roller and the second correction roller approach each other to the first limit distance.

[0010] When the first rubber tooth moves to the second limit position one, the second rubber tooth is located at the second limit position two. At this time, the first rubber tooth is in close contact with the first actuating rod, and the first actuating rod is pushed to the second limit position three by the first rubber tooth. The second rubber tooth is in close contact with the second actuating rod, and the second actuating rod is pushed to the second limit position four by the second rubber tooth. At this time, the spring is compressed, and the first roller bracket and the second roller bracket move away from each other, so that the first correction roller and the second correction roller move away from each other to the second limit distance.

[0011] Preferably, the conveying assembly includes an active conveying roller, a driven conveying roller, and a conveying motor. The active and driven conveying rollers are rotatably mounted on the mounting frame via bearings. The active and driven conveying rollers are connected by a conveyor belt.

The conveyor motor is fixedly mounted on the conveyor frame and is drively connected to the first active feed wheel.

[0013] Preferably, the conveyor frame is equipped with a fixing plate, the top plane of which is at the same height as the top plane of the feeding belt. This ensures that the calibrating roller can accurately clamp the wire mesh during operation, guaranteeing effective contact between the calibrating roller and both sides of the wire mesh, thus ensuring effective clamping.

[0014] Compared with the prior art, the present invention has the following advantages: In the wire mesh feeding process, the present invention uses reciprocating correction rollers on both sides to clamp and correct the wire mesh fed through the extension component, preventing material jamming and ensuring smooth feeding. At the same time, the reciprocating operation ensures the uniform position of the wire mesh during the feeding process, thereby improving the yield of solar cell production.

The base plate 1 is used to support the mounting frame 2, and the mounting frame 2 is welded and fixed to the base plate 1.

[0024] The conveying assembly is mounted on the mounting frame 2 and is used to convey the extension assembly 11. The conveying assembly includes a driving conveying roller 31, a driven conveying roller 32, and a conveying motor. The driving conveying roller 31 and the driven conveying roller 32 are rotatably mounted on the mounting frame 2 via bearings and are connected by a conveyor belt 4. The conveying motor is fixedly mounted on the mounting frame 2 and is connected to the driving conveying roller 31. The extension plate 110 is connected to the conveyor belt 4. The conveyor belt 4 is connected to one end of the extension plate 110 in the extension assembly 11 and is used to convey the extension assembly 11.

[0025] The extension assembly 11 is used for receiving and conveying the wire mesh. The extension assembly 11 includes an extension plate 110, a conveyor frame 111, a first active feed wheel 113, a second active feed wheel 116, a first driven feed wheel, a second driven feed wheel, and a conveyor motor 112. The extension plate 110 is mounted on the conveyor assembly, and the conveyor frame 111 is mounted on the extension plate 110.

The conveyor motor 112 is fixedly mounted on the conveyor frame 111, and is drive-connected to the first active feed wheel 113. The conveyor shaft of the conveyor motor 112 is connected to the connecting shaft 114 for power output to the first active feed wheel 113.

[0026] The correction component 6 is used to correct the wire mesh during the conveying process of the extension component 11. The correction component 6 includes a connecting plate 5, a spring 51, a limiting rod 52, a first actuating plate, a second actuating plate 7, a roller frame 8, a correction roller group 10, a correction platform 61, a driven shaft 62, a transmission belt 63, a driven wheel 64, a first actuating rod 65, a first connecting paddle 66, a drive shaft 67, a second connecting paddle 68, a second actuating rod 69, a drive wheel 610, a first rubber tooth 611, a motor 612, and a second rubber tooth 613, wherein: The outer side wall of the mounting bracket 2 is provided with a rod hole. One end of the limiting rod 52 is movably inserted into the rod hole and slides along the axial direction of the rod hole. The other end of the limiting rod 52 is fixed on the connecting plate 5. The spring 51 is fitted on the outer surface of the limiting rod 52, and one end of the spring 51 abuts against the connecting plate 5 and the other end abuts against the mounting bracket 2.

[0027] The roller frame 8 includes a first roller bracket and a second roller bracket. The connecting plate 5 on the left is designated as the first connecting plate, and the connecting plate 5 on the right is designated as the second connecting plate. The first roller bracket is fixedly connected to the first connecting plate, and the second roller bracket is fixedly connected to the second connecting plate. The correction roller assembly 10 includes a first correction roller and a second correction roller. The first correction roller is mounted on the first roller bracket via a first roller shaft 9, and the second correction roller is mounted on the second roller bracket via a second roller shaft. The first and second correction rollers are located on opposite sides of the extension assembly 11, respectively, for the movable clamping and correction of the wire mesh conveyed by the extension assembly 11.

[0028] The correction platform 61 is fixedly connected to the mounting bracket 2, and the correction platform 61 is located above the extension assembly 11. The driven wheel 64 is rotatably mounted on the correction platform 61 via the driven shaft 62, and the driving wheel 610 is rotatably mounted on the correction platform 61 via the driving shaft 67. The driving wheel 610 and the driven wheel 64 are connected by a transmission belt 63. The transmission belt 63 is provided with a first rubber tooth 611 and a second rubber tooth 613, which are equally spaced on the outer surface of the transmission belt 63. The first rubber tooth 611 and the second rubber tooth 613 act on the first actuating lever 65 and the second actuating lever 69, respectively. The first actuating lever 65 and the second actuating lever 69 are slidably mounted on the correction platform 61, with the first actuating lever 65 closer to the transmission belt 63 side of the first rubber tooth 611, and the second actuating lever 69 closer to the transmission belt 63 side of the second rubber tooth 613. That is, the first actuating lever 65 and the second actuating lever 69 are arranged in a centrally symmetrical structure on both sides of the transmission belt 63. The first rubber tooth 611 acts on the second actuating lever 69, and the second rubber tooth 613 acts on the first actuating lever 65. The first and second actuating plates 7 are slidably mounted on the correction platform 61. One end of the first actuating plate is fixedly connected to the first actuating rod 65 via a first connecting piece 66, while the other end is fixedly connected to the first roller bracket. One end of the second actuating plate 7 is fixedly connected to the second actuating rod 69 via a second connecting piece 68, while the other end is fixedly connected to the second roller bracket. The pushing limit of the first rubber tooth 611 to the second actuating rod 69 is when the distance between the first and second actuating plates 7 is at its maximum. The pushing limit of the second rubber tooth 613 to the first actuating rod 65 is when the distance between the first and second actuating plates 7 is at its maximum. A motor 612 is mounted on the top horizontal plate of the correction platform 61, and the motor 612 is connected to the drive shaft 67. The output shaft of the motor 612 is connected to the drive shaft 67 via a coupling for driving the drive shaft 67.

[0029] When the first rubber tooth 611 moves to the first limit position one, the second rubber tooth 613 is located at the first limit position two. At this time, the first rubber tooth 611 separates from the first actuating rod 65, and the second rubber tooth 613 separates from the second actuating rod 69. The spring 51 resets, and the first roller bracket and the second roller bracket approach each other until they reach the limit position under the reset action of the spring 51. At this time, the first actuating rod 65 is located at the first limit position three, and the second actuating rod 69 is located at the first limit position four. The first correction roller and the second correction roller approach each other to the first limit distance.

[0030] When the first rubber tooth 611 moves to the second limit position one, the second rubber tooth 613 is located at the second limit position two. At this time, the first rubber tooth 611 is in close contact with the first actuating rod 65, and the first actuating rod 65 is pushed to the second limit position three by the first rubber tooth 611. The second rubber tooth 613 is in close contact with the second actuating rod 69, and the second actuating rod 69 is pushed to the second limit position four by the second rubber tooth 613. At this time, the spring 51 is compressed, and the first roller bracket and the second roller bracket move away from each other, so that the first correction roller and the second correction roller move away from each other to the second limit distance.

[0031] During the clamping process, the motor 612 drives the drive shaft 67 to rotate. With the cooperation of the driven wheel 64 and the drive wheel 610, the transmission belt 63 rotates. During the rotation of the transmission belt 63, the two rubber teeth 611 act simultaneously on the second actuating rod 69 and the first actuating rod 65, which can push the first actuating rod 65 and the second actuating rod 69 to move towards the middle position in sync. Thus, the first actuating plate and the second actuating plate 7 cooperate to achieve the retraction clamping of the two roller frames 8. The rubber teeth 611 are made of soft rubber material. After the first actuating rod 65 and the second actuating rod 69 are in position, the rubber teeth 611 are squeezed and deformed through the first actuating rod 65 and the second actuating rod 69, which realizes the release of the first actuating rod 65 and the second actuating rod 69. This can cooperate to realize the clamping and correction operation of the wire mesh position correction process.

[0032] A fixing plate 12 is provided on the conveyor frame 111. The top side plane of the fixing plate 12 is at the same height as the top plane of the feeding belt 115. The fixing plate 12 is fixedly connected to the wire mesh production mechanism. The wire mesh slides into the wire mesh production mechanism along the fixing plate 12 under the conveying of the feeding belt 115.

[0033] The mounting frame 2 has a rod hole on its side wall, through which a limiting rod 52 is inserted. One end of the limiting rod 52 is fixed to the connecting plate 5. A spring 51 is fixed between the connecting plate 5 and the opposite side of the mounting frame 2, and the spring 51 is fitted outside the limiting rod 52. Under the action of the correction component 6, the two roller frames 8 are retracted. When the rubber teeth 611 constrain and push the first actuating rod 65 and the second actuating rod 69, the spring 51 in the connecting plate 5 can be compressed. After the rubber teeth 611 loses its constraint on the first actuating rod 65 and the second actuating rod 69, the roller frame 8 can be pushed back to its original position under the expansion of the spring 51, and the wire mesh can be clamped and corrected. This can be repeated cyclically to ensure that the position of the wire mesh is uniform during the feeding process, thereby reducing the defect rate of solar cell production.

[0034] In the manufacturing process of solar cells, wire mesh is an important material. Before use, the wire mesh needs to be cleaned. After conveying, the wire mesh is loaded through a conveying mechanism. During loading, the active conveying roller 31 rotates with the help of the conveying motor, which in turn rotates the conveyor belt 4. This allows the extension component 11 to move forward, causing the extension component 11 and the fixed plate 12 to extend in a staggered manner, ensuring a stable material feeding process. During conveying, the wire mesh falls on one end of the feeding belt 115. Under the action of the conveying motor 112, the connecting shaft 114 rotates. With the help of the feeding wheel 113, the feeding belt 115 rotates, enabling the conveying of the wire mesh and the loading process. This extends the conveying distance and ensures a stable loading process.

[0035] During the wire mesh feeding process, due to the poor conveying shape of the wire mesh during stacking, the roller frames 8 on both sides of the extension component 11 are moved during the conveying process to tighten the gap between the two roller frames 8. This reduces the gap between the correction rollers 10 on the two roller frames 8. By intermittently clamping the wire mesh during the wire mesh conveying process, the feeding angle of the wire mesh can be corrected to avoid jamming during the feeding process. At the same time, it can ensure the pressing state between the wire mesh and the battery cells after the wire mesh is fed.

[0036] In use, this clamping mechanism is installed between the wire mesh production mechanism and the wire mesh pretreatment mechanism. The fixing plate 12 is fixedly connected to the wire mesh production mechanism. At this time, the conveyor motor is started, which drives the active conveyor roller 31 to rotate, thereby driving the driven conveyor roller 32. The active and driven conveyor rollers 31 and 32 drive the conveyor belt 4 to rotate. Since the conveyor belt 4 is connected to one end of the extension plate 110 in the extension assembly 11, the conveying of the conveyor belt 4 drives the extension plate 110 to move. When the extension plate 110 moves into the wire mesh pretreatment mechanism, the conveyor motor stops rotating. The conveyor motor 112 is started, which drives the first active feed roller 113, the second active feed roller 116, the first driven feed roller, and the second driven feed roller to rotate, thereby driving the belt drive above. The wire mesh pretreatment mechanism places the wire mesh on the first and second drive belts. When motor 612 is started, it rotates clockwise, driving the drive wheel 610 and driven wheel 64 to rotate, which in turn drives the third transmission belt 63 to rotate. The third transmission belt 63 drives the first rubber teeth 611 and the second rubber teeth 613 to move. When the first rubber teeth 611 moves to the first actuating lever 65, the second rubber teeth 613 moves to the second actuating lever 69. At this time, motor 612 continues to rotate clockwise, and the first rubber teeth 611 pushes the first actuating lever 65 to move outward (the first actuating lever 65 slides in a groove). The movement of the first actuating lever 65 drives the movement of the first connecting plate 66, which in turn drives the movement of the first actuating plate. The movement of the first actuating plate drives the movement of the first roller bracket. The outward movement of the first roller bracket compresses the spring 51, and at the same time, the movement of the first roller bracket drives the first correction roller to move outward. The second rubber tooth 613 pushes the second actuating lever 69 outward (the second actuating lever 69 slides within a groove). The movement of the second actuating lever 69 causes the second connecting plate 68 to move, which in turn causes the second actuating plate to move. The movement of the second actuating plate causes the second roller bracket to move. The outward movement of the second roller bracket compresses the spring 51, and simultaneously, the movement of the second roller bracket causes the second correction roller to move outward. This continues until the first actuating lever 65 moves to the second limit position three, and the second actuating lever 69 moves to the second limit position four. At this point, the distance between the first and second correction rollers is at its maximum. The motor 612 continues to rotate clockwise. Due to the elasticity of the third transmission belt 63, the first rubber tooth 611 is misaligned with the first actuating lever 65, and the second rubber tooth 613 is misaligned with the second actuating lever 69. That is, the first rubber tooth 611 separates from the first actuating lever 65, and the second rubber tooth 613 separates from the second actuating lever 69. At this time, spring 51 returns to its original position, and the first and second transmission belts transport the wire mesh between the first and second correction rollers.Spring 51 resets and pushes the first roller bracket and the second roller bracket to move inward. The first roller bracket pushes the first correction roller to move inward, and the second roller bracket pushes the second correction roller to move inward, until the first correction roller and the second correction roller collide with the wire mesh, thus correcting the position of the wire mesh. At this time, the first actuating lever 65 and the second actuating lever 69 are closest to each other, and the motor 612 continues to rotate clockwise. At this time, the second rubber tooth 613 pushes the first actuating lever 65 to move outward, and the first rubber tooth 611 pushes the second actuating lever 69 to move outward. The first actuating lever 65 pushes the first actuating plate, which in turn pushes the first roller bracket to move outward, and the second actuating lever 69 pushes the second actuating plate, which in turn pushes the second roller bracket to move outward, thus causing the first correction roller and the second correction roller to move outward, separating the first correction roller and the second correction roller from the wire mesh, completing the wire mesh correction. The calibrated wire mesh is conveyed into the wire mesh production mechanism by the first and second drive belts. This process is repeated to achieve complete wire mesh calibration. This embodiment can correct the position of the wire mesh during conveying, preventing jamming during transport. It also corrects the clamping of the wire mesh, preventing jamming during loading.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
