Description

Technical Field

[0001] This application relates to the field of photovoltaic cell production equipment technology, specifically a cell conveying device. Background Technology

[0002] In the photovoltaic cell production process, large-sized cells need to be cut into multiple smaller cell pieces, which are then transported to the next stage of the process via a cell conveying device.

[0003] Conventional cell conveying devices can refer to the conveying mechanism in CN219286433U, which uses multiple sets of parallel conveyor lines connected to the same motor drive through gears and synchronous belts to achieve simultaneous movement of multiple sets of conveyor lines.

[0004] However, this type of conveyor mechanism is complex and fixed, difficult to disassemble and assemble, and inconvenient to replace. Furthermore, because the motor, drive shaft, and gears on the drive shaft are stationary, the synchronous belt may become stuck when adjusting the separation angle between the conveyor lines, causing wear or even disengagement of the synchronous belt due to the angle between the two gears. Additionally, existing technology uses a belt to connect the drive motor and the conveyor mechanism, which applies stress to the belt when adjusting the conveyor's angle, leading to severe wear on one side of the belt. Utility Model Content

[0005] This application addresses the problems of existing solar cell conveying devices being complex in structure, inconvenient to disassemble and assemble, and difficult to debug, by providing a solar cell conveying device with a simple structure that is easy to adjust and maintain.

[0006] The technical solution of this application is as follows: A battery cell conveying device, comprising a driving mechanism and at least two conveying mechanisms; wherein:

[0007] The drive mechanism includes a support frame, a drive component, a first drive shaft, and a plurality of first gears. The first drive shaft extends rotatably along a first direction and is mounted on the support frame. The plurality of first gears are detachably and spaced apart on the first drive shaft. The fixed end of the drive component is mounted on the support frame, and the movable end of the drive component is connected to the first drive shaft in a transmission manner.

[0008] Each conveying mechanism is installed at intervals on the support frame along the first direction. Each conveying mechanism is used to convey one battery cell. Each conveying mechanism includes a carrier frame, a second drive shaft, a second gear, a synchronous pulley, and a conveyor belt. The second gear and the synchronous pulley are both installed on the second drive shaft, which is rotatably mounted on the carrier frame. The conveyor belt is fitted onto the carrier frame along the second direction, and the synchronous pulley abuts against the inner side of the conveyor belt. The second direction is perpendicular to the first direction. The second gear of each conveying mechanism corresponds to and meshes with one of the first gears of the drive mechanism.

[0009] This application is assembled from a drive mechanism and a conveying mechanism. The drive mechanism adopts gear transmission, and the power is transmitted through the meshing of the first gear and the second gear. Since the first gear is located on the drive mechanism and the second gear is located on the conveying mechanism, each conveying mechanism and the drive mechanism are detachably connected, which is convenient for disassembly and assembly. It is also convenient to increase or decrease the number of conveying mechanisms according to the actual working conditions, which has high compatibility. After adjusting the angle between the conveying mechanisms, the transmission process will not cause damage to the first gear and the second gear, which is convenient for later maintenance, reduces the difficulty of assembly and debugging, extends the service life, and makes later maintenance and replacement more convenient.

[0010] Optionally, a first keyway is provided on the first drive shaft, and a second keyway is provided on each of the first gears. Each of the first gears is mounted on the first drive shaft by means of a key engaging with the first keyway and the second keyway.

[0011] The first gear is connected to the first drive shaft by a key and keyway, which is simple in structure and easy to disassemble and assemble.

[0012] Optionally, the drive mechanism further includes at least one connecting block, which is mounted on the support frame and rotatably connected to the middle of the first drive shaft.

[0013] By setting a connecting block in the middle of the first drive shaft to support it, deformation of the middle of the first drive shaft can be avoided, which would affect the transmission.

[0014] Optionally, the second gear and the synchronizing pulley are located on the same side or both sides of the support frame.

[0015] Placing the second gear and the synchronizing pulley on the same side of the support frame facilitates installation and improves assembly efficiency; distributing the second gear and the synchronizing pulley on both sides of the support frame optimizes the stress state of the second drive shaft and prevents deformation of the second drive shaft.

[0016] Optionally, each conveying mechanism also includes a carrier component, which is horizontally mounted on top of the carrier frame, with its upper surface serving as a bearing surface for supporting the conveyor belt.

[0017] By setting up load-bearing components to support the conveyor belt, it is possible to prevent the conveyor from being affected by sagging in the middle of the conveyor belt.

[0018] Optionally, a number of adsorption grooves are provided on the bearing surface, an adsorption cavity communicating with each adsorption groove is provided inside the bearing component, and an adsorption hole is provided on the conveyor belt; an external negative pressure source is connected to the adsorption cavity and adsorbs the battery cells onto the conveyor belt through the adsorption grooves and adsorption holes.

[0019] By combining the adsorption grooves on the carrier with the adsorption holes on the conveyor belt, the battery cells can be reliably adsorbed, preventing them from moving on the conveyor belt.

[0020] Optionally, a light source is installed below the carrier, and a camera is installed above the carrier. The camera and the light source work together to take pictures, locate, and inspect the appearance of the battery cells on the conveyor belt.

[0021] By installing cameras and light sources above and below the conveyor belt of the conveyor mechanism, the battery cells conveyed on the conveyor belt can be detected, making it easier to remove unqualified battery cells in a timely manner.

[0022] Optionally, each conveying mechanism also includes a tension adjusting assembly for adjusting the tension of the conveyor belt; the tension adjusting assembly includes a tensioning bracket and a tensioning wheel, the tensioning wheel being rotatably mounted on the tensioning bracket and located on the conveying path of the conveyor belt, the tensioning wheel abutting against the inner side of the conveyor belt, and the tensioning bracket being adjustablely mounted on the support frame.

[0023] By installing a tension adjustment component on the conveyor mechanism to adjust the tension of the conveyor belt, it is possible to prevent the conveyor belt from slipping due to insufficient tension or breaking due to excessive tension.

[0024] Optionally, the cell conveying device also includes a support plate, and both the support frame and the carrier frame are mounted on the support plate; an adjustment groove is provided at the position where the support plate connects to the carrier frame, and the adjustment groove is used to adjust the position of each carrier frame on the support plate.

[0025] By setting up a support plate, the drive mechanism and the conveying mechanism are assembled into a whole, thereby improving the overall stability of the battery cell conveying device.

[0026] Optionally, the adjustment groove is a waist-shaped hole or an arc-shaped hole.

[0042] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1-4 As shown, this application discloses a cell conveying device 1 for conveying cell wafers to subsequent workstations during solar cell module production. The cell conveying device 1 includes a drive mechanism 10 and at least two conveying mechanisms 20. The illustrated embodiment includes seven conveying mechanisms 20. Of course, depending on the actual number of cell wafers being connected, the number of conveying mechanisms 20 can be four, six, or eight, etc. No specific limit is placed on the number of conveying mechanisms 20 here.

[0044] Among them: such as Figure 5As shown, the drive mechanism 10 includes a support frame 11, a drive component 12, a first transmission shaft 13, and multiple first gears 14 (seven first gears 14 are shown in the figure; in actual operation, the number of first gears 14 can be the same as the number of conveying mechanisms 20, or can be increased or decreased as needed). The first transmission shaft 13 is rotatably mounted on the support frame 11 along a first direction 101 via bearings, and the multiple first gears 14 are detachably and spaced apart on the first transmission shaft 13. The fixed end of the drive component 12 is mounted on the support frame 11, and the movable end of the drive component 12 is connected to the first transmission shaft 13 for transmission. Optionally, the drive component 12 is a motor.

[0045] Each conveying mechanism 20 is installed at intervals along the first direction 101 on the support frame 11. Each conveying mechanism 20 is used to convey one battery cell (the battery cell conveyed by each conveying mechanism 20 is a small battery cell obtained by slicing a large battery cell). Figures 6-8 As shown, each conveying mechanism 20 includes a support frame 21, a second drive shaft 22, a second gear 23, a synchronous pulley 24, and a conveyor belt 25. The second gear 23 and the synchronous pulley 24 are both mounted on the second drive shaft 22, which is rotatably mounted on the support frame 21. The conveyor belt 25 is fitted onto the support frame 21 along a second direction 102, and the synchronous pulley 24 abuts against the inner side of the conveyor belt 25. The second direction 102 is perpendicular to the first direction 101. Figure 4 As shown, the second gear 23 of each conveying mechanism 20 corresponds to and meshes with a first gear 14 of the drive mechanism 10.

[0046] This application comprises a drive mechanism 10 and a conveying mechanism 20. The drive mechanism 10 uses gear transmission, with power transmitted through the meshing of a first gear 14 and a second gear 23. Since the first gear 14 is located on the drive mechanism 10 and the second gear 23 is located on the conveying mechanism 20, each conveying mechanism 20 is relatively independent of the drive mechanism 10, achieving a detachable connection. This facilitates easy assembly and disassembly, and allows for easy adjustment of the number of conveying mechanisms 20 according to actual working conditions. It offers high compatibility, facilitates later maintenance, eliminates the need to disassemble the mechanical structure, and allows for individual replacement of the conveyor belts on the conveying mechanisms. This reduces assembly and debugging difficulty, extends service life, and makes later maintenance and replacement more convenient. Furthermore, traditional drive mechanisms use belt drives to move the conveying mechanism. Adjusting the angle of the conveying mechanism can cause the rotating shaft, coupling, and motor to be out of sync, frequently resulting in shaft and coupling breakage. Secondly, the belt experiences stress from the angle adjustment, leading to easy belt wear. Therefore, the transmission engagement between the first gear 14 and the second gear 23 in this application can accommodate a certain angular offset, completing transmission even without complete meshing. For example, the adjustment threshold between the first gear 14 and the second gear 23 can be increased by extending the tooth length of the first gear 14 and the second gear 23 or by increasing the width of the first gear 14 and the second gear 23.

[0047] like Figure 5 As shown, optionally, a first keyway is provided on the first drive shaft 13, and a second keyway is provided on each of the first gears 14. Each of the first gears 14 is mounted on the first drive shaft 13 by means of a key engaging with the first keyway and the second keyway.

[0048] The first gear 14 and the first transmission shaft 13 are connected by a key and a keyway, which is simple in structure and easy to disassemble and assemble.

[0049] Optionally, the drive mechanism 10 further includes at least one connecting block 15, which is mounted on the support frame 11 and rotatably connected to the middle of the first drive shaft 13. Specifically, a bearing is installed in the connecting block 15, through which the first drive shaft 13 passes.

[0050] By providing a connecting block 15 in the middle of the first drive shaft 13 to support the first drive shaft 13, deformation of the middle of the first drive shaft 13 that would affect transmission can be avoided.

[0051] like Figures 6-8 As shown, optionally, the second gear 23 and the synchronous pulley 24 are located on the same side or on both sides of the support frame 11.

[0052] By placing the second gear 23 and the synchronous pulley 24 on the same side of the support frame 11, installation is convenient and assembly efficiency can be improved; by distributing the second gear 23 and the synchronous pulley 24 on both sides of the support frame 11, the stress state of the second drive shaft 22 can be optimized and deformation of the second drive shaft 22 can be prevented.

[0053] Optionally, each conveying mechanism 20 also includes a carrier 26, which is horizontally mounted on the top of the carrier frame 21. The upper surface of the carrier 26 is a bearing surface for bearing the conveyor belt 25.

[0054] By providing a support member 26 to support the conveyor belt 25, it is possible to prevent the conveyor belt 25 from sagging in the middle and affecting the conveying process.

[0055] Optionally, a number of adsorption grooves are provided on the bearing surface, an adsorption cavity communicating with each adsorption groove is provided inside the bearing member 26, and an adsorption hole 251 is provided on the conveyor belt 25; an external negative pressure source is connected to the adsorption cavity and adsorbs the battery cells onto the conveyor belt 25 through the adsorption grooves and adsorption holes 251.

[0056] By cooperating with the adsorption groove on the carrier 26 and the adsorption hole 251 on the conveyor belt 25, the battery cells can be reliably adsorbed, thus preventing the battery cells from moving on the conveyor belt 25.

[0057] Optionally, a light source 261 is installed below the carrier 26, and a camera is installed above the carrier 26. The camera and the light source 261 work together to take pictures, locate, and inspect the battery cells on the conveyor belt 25.

[0058] By setting cameras and light sources 261 above and below the conveyor belt 25 of the conveying mechanism 20, the solar cells conveyed on the conveyor belt 25 can be inspected, making it easy to remove unqualified solar cells in a timely manner, such as those with defects such as chipped edges or missing corners.

[0059] In one embodiment, an installation gap is formed between the top of the support frame 21 and the support member 26, the two ends of the light source 261 are respectively mounted on the support frame 11, and the middle part of the light source 261 passes through the installation gap of each conveying mechanism 20 and does not contact each conveying mechanism 20.

[0060] Optionally, each conveying mechanism 20 further includes a tension adjusting assembly 27 for adjusting the tension of the conveyor belt 25; the tension adjusting assembly 27 includes a tensioning bracket 271 and a tensioning wheel 272, the tensioning wheel 272 is rotatably mounted on the tensioning bracket 271 and located on the conveying path of the conveyor belt 25, the tensioning wheel 272 abuts against the inner side of the conveyor belt 25, and the tensioning bracket 271 is adjustablely mounted on the support frame 21.

[0061] By setting a tension adjustment component 27 on the conveying mechanism 20 to adjust the tension of the conveyor belt 25, it is possible to prevent the conveyor belt 25 from slipping due to insufficient tension or breaking due to excessive tension.

[0062] like Figure 1 As shown, optionally, the battery cell conveying device 1 also includes a support plate 30, and the support frame 11 and the carrier frame 21 are both mounted on the support plate 30; an adjustment groove 31 is provided at the position where the support plate 30 connects to the carrier frame 21, and the adjustment groove 31 is used to adjust the position of each carrier frame 21 on the support plate 30.

[0063] By setting the support plate 30, the drive mechanism 10 and the conveying mechanism 20 are assembled into a whole, thereby improving the overall stability of the battery cell conveying device 1.

[0064] Optionally, the adjustment groove 31 is a waist-shaped hole or an arc-shaped hole, and the support plate 30, together with the set screw or adjusting bolt, adjusts the position of the support frame 21.

[0065] By setting an adjustment groove 31 on the support plate 30, the position of the conveying mechanism 20 can be easily adjusted so that the angular relationship between each conveying mechanism 20 meets the usage requirements. By adjusting the angular relationship between adjacent conveying mechanisms 20, the spacing between the cells conveyed by adjacent conveying mechanisms 20 can be adjusted during the conveying process, which is convenient for subsequent stations to pick up or unload materials.

[0066] The working process of this application is as follows: the driving component 12 of the driving mechanism 10 drives the first transmission shaft 13 to rotate, the first transmission shaft 13 drives the first gear 14 to rotate synchronously, the first gear 14 drives the second gear 23 meshing with it to rotate, the second gear 23 drives the second transmission shaft 22 to rotate, the second transmission shaft 22 drives the synchronous wheel 24 to rotate, and drives the conveyor belt 25 to rotate. Finally, the conveyor belt 25 picks up the battery cells on one side and drives the battery cells to be transported in the second direction 102 on the other side.

[0067] The foregoing has provided a sufficiently detailed and specific description of this application. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within the protection scope of this application.
