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 segments, which are then transported to subsequent processing stations via a conveyor system.

[0003] Conventional conveying devices can be referenced from the conveying mechanism in CN219286433U, which includes multiple sets of parallel conveyor lines. Each set of conveyor lines is used to convey one battery cell, and each set of conveyor lines is connected to the same motor via gears and synchronous belts, thus achieving the effect of driving multiple sets of conveyor lines simultaneously with one motor. This type of conveying device has a complex and relatively fixed transmission structure, is difficult to disassemble and assemble, inconvenient to replace, and cannot increase or decrease the number of conveyor lines, resulting in poor overall compatibility and difficult maintenance. Utility Model Content

[0004] This application addresses the problem of poor compatibility of existing transmission devices by providing a battery cell transmission device with better compatibility.

[0005] The technical solution of this application is as follows: A battery cell conveying device includes a driving mechanism, a transmission mechanism, and at least two conveying mechanisms; wherein:

[0006] Each conveying mechanism is spaced apart along a first direction. Each conveying mechanism includes a bracket, a first magnetic wheel, a first shaft, and a conveyor belt. The first magnetic wheel is fixedly installed on the first shaft, and the first shaft is rotatably installed on the bracket. The conveyor belt is fitted onto the bracket along a second direction, and the first shaft abuts against the inner side of the conveyor belt. The first direction is perpendicular to the second direction.

[0007] The transmission mechanism includes a second shaft and a plurality of second magnetic wheels that are matched with each first magnetic wheel. The second shaft extends along a first direction. Each conveying mechanism is detachably and spaced on the second shaft. Each second magnetic wheel is fixedly installed on the second shaft and is arranged opposite to the corresponding first magnetic wheel.

[0008] The movable end of the drive mechanism is connected to the second shaft drive.

[0009] The transmission mechanism of this application is detachably connected to each conveying mechanism. Power is transmitted through the first magnetic wheel and the second magnetic wheel. There are no redundant transmission components such as synchronous belts in the prior art. It is easy to disassemble and assemble, and it is convenient to increase or decrease the number of conveying mechanisms according to actual working conditions. It has high compatibility and is convenient for later maintenance. In addition, since the two magnetic wheels are non-contact transmissions, the wear and dust caused by traditional synchronous belt drives can be reduced.

[0010] Optionally, the gap between the first magnetic wheel and the second magnetic wheel is 0.5-3mm.

[0011] Maintaining a suitable gap between the two magnetic wheels ensures both non-contact transmission and reliable power transmission.

[0012] Optionally, the drive mechanism includes a motor, a synchronous belt, and two synchronous pulleys. The two synchronous pulleys are respectively mounted on the movable end of the motor and on the second shaft, and the synchronous belt is fitted onto the two synchronous pulleys.

[0013] The drive mechanism adopts a structure where the motor drives the synchronous belt, which is convenient to install and maintain, and has low cost.

[0014] Optionally, each conveying mechanism has a U-shaped groove with an opening along the second direction on its support, and the second shaft passes through the U-shaped groove of each support and is detachably connected to each support through a bearing seat.

[0015] By opening a U-shaped groove on the support of the conveying mechanism, the second shaft of the transmission mechanism can be positioned by inserting it into the U-shaped groove through the opening of the U-shaped groove, which is convenient for installation and also makes it easy to remove the second shaft from the support.

[0016] Optionally, each conveying mechanism also includes an adjusting plate and a support base. The adjusting plate is detachably mounted on the upper end of the support base and its position on the support base is adjustable. A bracket is fixedly mounted on the adjusting plate.

[0017] By setting an adjustment plate between the conveying mechanism and the support base, the height and horizontal position of the conveying mechanism can be easily adjusted, increasing the installation accuracy of the conveying mechanism and facilitating the adjustment of the relative position of two adjacent conveying mechanisms.

[0018] Optionally, each conveying mechanism further includes a top screw mounting block and a top screw. The adjusting plate has a first adjusting hole extending in a first direction. The top screw mounting block is fixedly mounted on the support base. One end of the top screw is threaded to the top screw mounting block, and the other end of the top screw abuts against the adjusting plate. The adjusting plate is configured to adjust the position of the bracket via the top screw and the first adjusting hole.

[0019] An adjustment mechanism combining set screws and adjustment holes is used to adjust the installation position of the conveying mechanism mounted above the adjustment plate, mainly the installation angle. This ensures that adjacent conveying mechanisms are close at the input end of the sheet and far apart at the output end, facilitating the adjustment of the output spacing between adjacent sheets. This adjustment mechanism has a simple structure and is easy to adjust.

[0020] Optionally, the cell conveying device also includes a base plate, and a second adjustment hole is provided at the lower end of the support base. The extension direction of the second adjustment hole is the same as the first direction or the second direction. The support base is mounted on the base plate in an adjustable manner with respect to the position of the first fastener via the second adjustment hole.

[0021] By setting a base plate, all conveying mechanisms can be installed on the base plate, increasing overall stability; a second adjustment hole is opened at the lower end of the support base, which can adjust the relative position between each support base and reduce installation errors.

[0022] Optionally, each conveying mechanism further includes a tension adjusting assembly, which includes a tension block and a tension wheel. The tension wheel is rotatably mounted on the first end of the tension block and abuts against the conveyor belt. The second end of the tension block has a third adjusting hole. The tension adjusting assembly is installed on the conveying path of the conveyor belt in an adjustable manner with respect to the position of the second fastener through the third adjusting hole.

[0023] By installing tension adjustment components on the conveyor belt's conveying path, the conveyor belt can be kept at a suitable tension. The tension adjustment components use tensioning wheels, which can maintain a large contact area with the conveyor belt, reducing wear and extending its service life.

[0024] Optionally, each conveying mechanism includes a conveyor belt, a drive wheel fixedly mounted on a first shaft, the drive wheel abutting against the inner side of the conveyor belt, and a first magnetic wheel mounted on the outer side of the drive wheel.

[0025] The conveying mechanism uses a single conveyor belt, with the first magnetic wheel mounted on one side of the conveyor belt. The structure is simple and easy to assemble and disassemble.

[0026] Optionally, each conveying mechanism includes two conveyor belts, which are mounted on a support in parallel and spaced apart along a first direction and configured to jointly convey the sheet body along a second direction. Two drive wheels are fixedly mounted on a first shaft, and the two drive wheels abut against the inner side of the corresponding conveyor belts. A first magnetic wheel is mounted between the two drive wheels, or the first magnetic wheel is mounted on the outer side of one of the drive wheels.

[0027] The conveying mechanism uses two conveyor belts to transport the sheet together, making the conveying smoother. When the first magnetic wheel is installed between the two conveyor belts, the drive wheels of the two conveyor belts are arranged on both sides of the first magnetic wheel, which can save space in the width direction and allow more conveying mechanisms to be installed in a limited space.

[0043] 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.

[0044] like Figures 1-3 As shown, this application discloses a cell conveying device 1, used to transport cells to subsequent workstations in the production of solar cell modules. The cell conveying device 1 mainly includes a drive mechanism 30, a transmission mechanism 20, and at least two conveying mechanisms 10; the illustrated embodiment includes four conveying mechanisms 10.

[0045] Wherein: each conveying mechanism 10 is arranged at intervals along the first direction 101. For example: Figures 4-6As shown, each conveying mechanism 10 includes a bracket 11, a first magnetic wheel 12, a first shaft 13, and a conveyor belt 14. The first magnetic wheel 12 is fixedly mounted on the first shaft 13, and the first shaft 13 is rotatably mounted on the bracket 11. The conveyor belt 14 is fitted onto the bracket 11 along a second direction 102, and the first shaft 13 abuts against the inner side of the conveyor belt 14. The first direction 101 is perpendicular to the second direction 102. The axis of the first shaft 13 is parallel to the first direction 101.

[0046] like Figure 7 , Figure 8 As shown, the transmission mechanism 20 includes a second shaft 21 and a plurality of second magnetic wheels 22 that are matched with each of the first magnetic wheels 12. The second shaft 21 extends along a first direction 101. Figure 1 As shown, each conveying mechanism 10 is detachably and spaced apart on the second shaft 21, and each second magnetic wheel 22 is fixedly installed on the second shaft 21 and is arranged opposite to the corresponding first magnetic wheel 12; the movable end of the drive mechanism 30 is connected to the second shaft 21 for transmission.

[0047] During the actual transport of battery segments, the drive mechanism 30 drives the second shaft 21 to rotate, causing each second magnetic wheel 22 fixedly installed on the second shaft 21 to rotate as well. Through magnetic force, each first magnetic wheel 12, which is opposite to each second magnetic wheel 22, rotates, thereby causing the first shaft 13 to rotate on the bracket 11, which in turn drives the conveyor belt 14 that abuts against the first shaft 13 to rotate, ultimately achieving the effect of moving the battery segments carried by the conveyor belt 14.

[0048] This application employs magnetic wheel transmission. The working principle of the magnetic wheel is to transmit power through the interaction of the attractive and repulsive forces of magnets. Specifically, magnets are embedded inside the magnetic wheel, and the magnetic fields generated by these magnets allow the magnetic wheel to attract or repel external magnetic fields, thereby achieving non-contact power transmission. This reduces wear and friction, improves transmission efficiency, and allows for a more compact structural design.

[0049] Magnetic wheel drives have the following advantages:

[0050] 1. Reduced wear and friction: Due to the non-contact transmission, wear and friction of mechanical parts are reduced, extending the service life of the equipment.

[0051] 2. Improved efficiency: Non-contact transmission reduces energy loss and improves transmission efficiency.

[0052] 3. Compact structure: Since no physical contact is required, a more compact design can be achieved, saving space.

[0053] The transmission mechanism 20 of this application is detachably connected to each conveying mechanism 10. Power is transmitted through the first magnetic wheel 12 and the second magnetic wheel 22. There are no redundant transmission components such as the synchronous belt 32 in the prior art. It is easy to disassemble and assemble, and it is convenient to increase or decrease the number of conveying mechanisms 10 according to actual working conditions. It has high compatibility and is convenient for later maintenance. In addition, since the two magnetic wheels are non-contact transmissions, the wear and dust caused by traditional synchronous belt drives can be reduced.

[0054] like Figure 1 , Figure 3 As shown, optionally, the gap between the first magnetic wheel 12 and the second magnetic wheel 22 is 0.5-3mm. That is, there is a gap between the wheel surface of the first magnetic wheel 12 and the wheel surface of the second magnetic wheel 22. This gap can be any value between 0.5mm and 3mm, for example, it can be 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc.

[0055] Maintaining a suitable gap between the two magnetic wheels ensures both non-contact transmission and reliable power transmission, while also providing adjustment space for subsequent adjustments to the spacing between adjacent sets of conveying mechanisms 10.

[0056] like Figures 1-3 As shown, each conveying mechanism 10 can use one conveyor belt 14 or two conveyor belts 14. The illustrated embodiment uses two conveyor belts 14.

[0057] When each conveying mechanism 10 includes a conveyor belt 14, a drive wheel 18 is fixedly mounted on the first shaft 13, the drive wheel 18 abuts against the inner side of the conveyor belt 14, and the first magnetic wheel 12 is mounted on the outer side of the drive wheel 18.

[0058] The conveying mechanism 10 uses a conveyor belt 14 and the first magnetic wheel 12 is installed on one side of the conveyor belt 14. The structure is simple and easy to disassemble and assemble.

[0059] When each conveying mechanism 10 includes two conveyor belts 14, the two conveyor belts 14 are mounted on the bracket 11 in parallel at intervals along the first direction 101 and are configured to jointly convey the sheet body along the second direction 102. Two drive wheels 18 are fixedly mounted on the first shaft 13, and the two drive wheels 18 respectively abut against the inner side of the corresponding conveyor belt 14. A first magnetic wheel 12 is installed between the two drive wheels 18, or the first magnetic wheel 12 is installed on the outer side of one of the drive wheels 18.

[0060] The conveying mechanism 10 uses two conveyor belts 14 to jointly convey the sheet, making the conveying smoother. When the first magnetic wheel 12 is installed between the two conveyor belts 14, the drive wheels 18 of the two conveyor belts 14 are arranged on both sides of the first magnetic wheel 12, which can save space in the width direction and allow more conveying mechanisms 10 to be installed in a limited space. When the first magnetic wheel 12 is installed on the outer side of one of the drive wheels 18, it is convenient to replace and maintain the first magnetic wheel 12.

[0061] Optionally, the drive wheel 18 of the conveying mechanism 10 can be a gear or a smooth wheel. Correspondingly, the conveyor belt 14 can be an internal toothed belt or a flat belt.

[0062] Please see Figures 4-6 Optionally, each conveying mechanism 10 has a U-shaped groove 111 on its support 11 that opens along the second direction 102. See also Figure 1 , Figure 2 The second shaft 21 of the transmission mechanism 20 passes through the U-shaped groove 111 of each bracket 11 and through the bearing seat 23 (see... Figure 7 , Figure 8 Each bearing seat 23 is detachably connected to each bracket 11. The number of bearing seats 23 is the same as the number of second magnetic wheels 22.

[0063] By creating a U-shaped groove 111 on the support 11 of the conveying mechanism 10, the second shaft 21 of the transmission mechanism 20 can be positioned by inserting it into the U-shaped groove 111 through its opening. This facilitates installation and also makes it easy to disassemble the second shaft 21 from the support 11. In practical applications, the number of bearing seats 23 and the second magnetic wheels 22 can be matched according to the actual number of conveying mechanisms 10, i.e., both bearing seats 23 and the second magnetic wheels 22 are detachably connected to the second shaft 21. When a conveying mechanism 10 is added to the second shaft 21 along the first direction 101, a bearing seat 23 and a second magnetic wheel 22 need to be added accordingly. The first end of the bearing seat 23 passes through the second shaft 21, and the second end of the bearing seat 23 is fixedly connected to the conveying mechanism 10. The second magnetic wheel 22 is fixedly installed on the second shaft 21 by a clamp. In one embodiment, the opening direction of the U-shaped groove can be different from the second direction 102, which allows for quick assembly and disassembly of the conveying mechanism 10 on the second shaft 21. In addition, if the bracket 11 is made relatively short, the disassembly and assembly of the conveying mechanism 10 on the second shaft 21 will not interfere with the bracket 11, and the U-shaped groove 111 may not be required.

[0064] Optionally, each conveying mechanism 10 also includes an adjusting plate 15 and a support base 16. The adjusting plate 15 is detachably mounted on the upper end of the support base 16 and the position of the adjusting plate 15 on the support base 16 is adjustable. The bracket 11 is fixedly mounted on the adjusting plate 15.

[0065] By setting an adjustment plate 15 between the conveying mechanism 10 and the support base 16, the height and horizontal position of the conveying mechanism 10 can be easily adjusted, thereby increasing the installation accuracy of the conveying mechanism 10.

[0066] To adjust the position of the conveying mechanism 10 in the horizontal plane, each conveying mechanism 10 may optionally include a top screw mounting block and a top screw. The adjusting plate 15 is provided with a first adjusting hole 151 extending along the first direction 101. The top screw mounting block is fixedly mounted on the support base 16. One end of the top screw is threaded to the top screw mounting block, and the other end of the top screw abuts against the adjusting plate 15. The adjusting plate 15 is configured to adjust the position of the bracket 11 via the top screw and the first adjusting hole 151.

[0067] An adjustment mechanism combining set screws and adjustment holes is used to adjust the installation position of the conveying mechanism 10 mounted above the adjustment plate 15, mainly the installation angle, so that the adjacent conveying mechanisms 10 are close to each other at the input end of the plate and far apart at the output end of the plate. This adjustment mechanism has a simple structure and is easy to adjust.

[0068] Optionally, each conveying mechanism 10 further includes a tension adjusting assembly 17, which includes a tension block 171 and a tension wheel 172. The tension wheel 172 is rotatably mounted on the first end of the tension block 171 and abuts against the conveyor belt 14. The second end of the tension block 171 has a third adjusting hole 173. The tension adjusting assembly 17 is adjustablely mounted on the conveying path of the conveyor belt 14 via the third adjusting hole 173 and the position of the second fastener. See also Figure 5 The third adjustment hole 173 is vertically arranged. The height of the tension wheel 172 is adjusted by adjusting the third adjustment hole 173 and the second fastener (not shown in the figure), thereby adjusting the tension of the conveyor belt 14 that is abutted by the tension wheel 172.

[0069] The number of tension adjustment components 17 in each conveyor mechanism 10 is the same as the number of its conveyor belts 14. When the conveyor mechanism 10 uses one conveyor belt 14, one tension adjustment component 17 is configured; when the conveyor mechanism 10 uses two conveyor belts 14, two tension adjustment components 17 are configured.

[0070] By installing a tension adjusting component 17 on the conveying path of the conveyor belt 14, the conveyor belt 14 can be kept at a suitable tension. The tension adjusting component 17 uses a tensioning wheel 172, which can maintain a large contact area with the conveyor belt 14, reduce the wear of the conveyor belt 14, and improve the service life of the conveyor belt 14.

[0071] like Figure 7 , Figure 8As shown, optionally, the drive mechanism 30 includes a motor 31, a synchronous belt 32 and two synchronous pulleys 33. The two synchronous pulleys 33 are respectively mounted on the movable end of the motor 31 and on the second shaft 21. The synchronous belt 32 is fitted onto the two synchronous pulleys 33. The fixed end of the motor 31 is mounted on the support seat 16 of one of the conveying mechanisms 10.

[0072] The drive mechanism 30 adopts a structure in which the motor 31 drives the synchronous belt 32, which is convenient to install and maintain and has low cost.

[0073] like Figures 1-3 As shown, optionally, the battery cell conveying device 1 also includes a base plate 40. The lower end of the support seat 16 of each conveying mechanism 10 is provided with a second adjustment hole 161. The extension direction of the second adjustment hole 161 is the same as that of the first direction 101 or the second direction 102. The support seat 16 is mounted on the base plate 40 in an adjustable manner with the first fastener via the second adjustment hole 161.

[0074] By setting the base plate 40, all conveying mechanisms 10 can be installed on the base plate 40, increasing the overall stability; a second adjustment hole 161 is opened at the lower end of the support 16, which can adjust the relative position between each support 16 and reduce installation error.

[0075] The working process of this application is as follows: When the motor 31 of the drive mechanism 30 drives the second magnetic wheel 22 to rotate via the synchronous belt 32 and the second shaft 21, the first magnetic wheel 12 opposite to the second magnetic wheel 22 rotates synchronously without contact, thereby driving the first shaft 13 to rotate. When the transmission wheel 18 installed on the first shaft 13 rotates with the first shaft 13, it drives the conveyor belt 14 of the conveying mechanism 10 to run.

[0076] like Figures 1-3 As shown, the cell conveying device 1 in the figure includes four conveying mechanisms 10 for conveying four cell wafers. The cell conveying device 1 is located after the cell dicing device. The dicing device divides a cell wafer into two cell wafers, and then the cell conveying device 1 conveys the cell wafers to the next stage. During the conveying process, the spacing between adjacent cell wafers can be adjusted through the first adjustment hole 151 and the second adjustment hole 161.

[0077] The cell conveying device 1 of this application can also adapt to the later stages of the industry where a single cell is divided into three or more cell segments, because each conveying mechanism 10 occupies less space. When it is necessary to add a conveying mechanism 10, it is only necessary to add a second magnetic wheel 22 corresponding to the newly added conveying mechanism 10 on the second shaft 21.

[0078] 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. The scope of protection claimed in this application is defined by the claims, and not by the above descriptions in the embodiments.
