[0002] In the production process of solar cells, the conveying direction of the solar cells may need to be changed in order to transport the solar cells to a predetermined position. Therefore, the solar cell conveying unit is equipped with a reversing conveying device for changing the conveying direction of the solar cells.

[0003] Existing reversing conveyor systems mostly use rotating conveyor belts to achieve direction changes. While this method can adjust the orientation of the solar cells, it requires additional rotary drive mechanisms, such as rotary motors and rotary support platforms, to rotate the conveyor belt. Furthermore, the conveyor belt has inertia during rotation, necessitating additional positioning structures for the solar cells. These additional structures not only increase the overall complexity of the device but also lead to larger device size, higher manufacturing costs, and greater maintenance difficulties.

[0017] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0018] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0019] like Figure 1-7 As shown, one embodiment of this utility model provides a reversible conveying device 10, which includes a first conveying mechanism 1 and a second conveying mechanism 2 for conveying products in different directions. The products may be battery cells or other items.

[0020] The first conveying mechanism 1 includes a first conveyor belt 11 and a first drive assembly 12 for driving the first conveyor belt 11 to convey products along a first direction. The second conveying mechanism 2 includes a second conveyor belt 21 and a second drive assembly 22 for driving the second conveyor belt 21 to convey products along a second direction.

[0021] After the product is placed on the first conveyor belt 11, the first conveyor belt 11 can transport the product along the first direction under the drive of the first drive component 12. After the product is placed on the second conveyor belt 21, the second conveyor belt 21 can transport the product along the second direction under the drive of the second drive component 22.

[0022] In this embodiment, the first conveying mechanism 1 and the second conveying mechanism 2 are movable relative to each other along a third direction, and the second conveyor belt 21 includes a plurality of conveying sections 211 spaced apart along a second direction and a connecting section 212 connecting two adjacent conveying sections 211. The connecting section 212 surrounds and forms a clearance groove 213 extending along a third direction, and the first conveyor belt 11 passes through the clearance groove 213 along a first direction.

[0023] like Figure 1 , 8 As shown in the figure, the x-axis represents the first direction of this paper, the y-axis represents the second direction, and the z-axis represents the third direction. The third direction is perpendicular to both the first and second directions. The first and second directions can be perpendicular, and the angle between them can be called an acute or obtuse angle. In this paper, the first and second directions are perpendicular.

[0024] For ease of explanation, the third direction is referred to as the vertical direction in this article. The first conveying mechanism 1 and the second conveying mechanism 2 are movable relative to each other in the vertical direction. The working principle of the reversing conveyor 10 is as follows: if the reversing conveyor 10 only needs to convey products in the first direction, the positions of the first conveying mechanism 1 and the second conveying mechanism 2 in the vertical direction are adjusted so that the height of the second conveyor belt 21 is lower than the height of the first conveyor belt 11. In this way, after receiving the products, the first conveyor belt 11 will continue to convey products in the first direction.

[0025] If it is necessary to change the product conveying direction from the first direction to the second direction, the height of the second conveyor belt 21 must first be lower than the height of the first conveyor belt 11. After the first conveyor belt 11 receives the product, if the product moves above the second conveyor belt 21 during the process of the product moving in the first direction, the relative positions of the first conveying mechanism 1 and the second conveying mechanism 2 in the vertical direction are adjusted so that the height of the second conveyor belt 21 is higher than the height of the first conveyor belt 11. In this way, the product will be lifted off the first conveyor belt 11 by the second conveyor belt 21. After that, the second conveyor belt 21 will convey the product in the second direction, thereby changing the product conveying direction.

[0026] In this embodiment, the first conveyor belt 11 and the second conveyor belt 21 are arranged in a cross shape. They move relative to each other in a third direction to realize the reverse conveying of products. Furthermore, the second conveyor belt 21 has a bent connecting section 212 in its structure. The connecting section 212 surrounds and forms a clearance groove 213. With the help of the clearance groove 213, the second conveyor belt 21 can effectively avoid the first conveyor belt 11 in the cross area, thus avoiding interference between the first conveyor belt 11 and the second conveyor belt 21.

[0027] The reversing conveying device 10 in this embodiment can change the conveying direction without an additional rotary drive mechanism, which simplifies the structural design, reduces the number of components, and lowers the overall weight and manufacturing cost of the device. At the same time, since there are no rotating parts, it also significantly improves the operational stability and service life of the equipment and reduces the difficulty of maintenance. The first conveying mechanism 1 includes two first conveyor belts 11 spaced apart along a second direction. The two first conveyor belts 11 can simultaneously support and convey the battery cells 200, making the conveying of the battery cells 200 more stable and reliable. To avoid interference between the two first conveyor belts 11 and the second conveyor belt 21, the second conveyor belt 21 includes two connecting sections 212 spaced apart along the second direction, and the conveying section 211 has three sections. The two connecting sections 212 form two clearance grooves 213, and the two first conveyor belts 11 pass through the two clearance grooves 213 respectively along a first direction.

[0028] It is conceivable that the number of first conveyor belts 11 in the first conveying mechanism 1 is not limited to two. In other embodiments of this utility model, the number of first conveyor belts 11 can be set to three or even more.

[0029] The first conveying mechanism 1 includes a first base frame 13, and the first driving assembly 12 includes a first driving member 121, a plurality of first rollers 122 and a plurality of second rollers (not shown in the figure) rotatably connected to the first base frame 13. The plurality of first rollers 122 are rotatably connected to a first side of the first base frame 13 in a second direction, and the plurality of second rollers are rotatably connected to a second side of the first base frame 13 in a second direction. The plurality of first rollers 122 and the plurality of second rollers are arranged in a one-to-one correspondence along the second direction.

[0030] For ease of explanation, let's assume that the two first conveyor belts 11 in the same first conveying mechanism 1 are first conveyor belt 11a and first conveyor belt 11b. First conveyor belt 11a is driven by multiple first rollers 122, meaning that when one first roller 122 rotates, the other first rollers 122 will also rotate under the action of first conveyor belt 11a. The multiple first rollers 122 support first conveyor belt 11a, enabling it to maintain a preset shape. First conveyor belt 11b is driven by multiple second rollers, meaning that when one second roller rotates, the other second rollers will also rotate under the action of first conveyor belt 11b. The multiple second rollers support first conveyor belt 11b, enabling it to maintain a preset shape.

[0031] The first driving member 121 is used to drive at least one of the plurality of first rollers 122 and the plurality of second rollers to rotate. The first driving assembly 12 also includes a first connecting shaft 123 connecting the corresponding first rollers 122 and second rollers. As described above, the plurality of first rollers 122 rotate simultaneously under the action of the first conveyor belt 11a, and the plurality of second rollers rotate simultaneously under the action of the first conveyor belt 11b. In this case, the first connecting shaft 123 connects the corresponding first rollers 122 and second rollers, enabling the plurality of first rollers 122 and the plurality of second rollers to rotate simultaneously. Thus, the first driving member 121 only needs to drive the rotation of one of the plurality of first rollers 122 and the plurality of second rollers to drive the plurality of first rollers 122 and the plurality of second rollers to rotate.

[0032] With the above configuration, a first drive unit 121 can drive two first conveyor belts 11 to rotate through multiple first rollers 122 and multiple second rollers, ensuring that the two first conveyor belts 11 can rotate synchronously, and reducing the number of drive units required, thereby reducing the cost and control difficulty of the reversing conveyor device 10.

[0033] The second conveying mechanism 2 includes a second base frame 23 and two second conveyor belts 21 respectively disposed on both sides of the second base frame 23 in the first direction. The two second conveyor belts 21 can simultaneously support and convey the battery cells 200, making the conveying of the battery cells 200 more stable and reliable.

[0034] The number of second conveyor belts in the second conveying mechanism is not limited to two. In other embodiments of this utility model, the number of second conveyor belts in the second conveying mechanism may be set to three or even more.

[0035] The second drive assembly 22 includes a second drive member 221, a plurality of third rollers 222 and a plurality of fourth rollers (not shown in the figure) rotatably connected to the second base frame 23. The plurality of third rollers 222 are rotatably connected to the first side of the second base frame 23 in the first direction, and the plurality of fourth rollers are rotatably connected to the second side of the second base frame 23 in the first direction. The plurality of third rollers 222 and the plurality of fourth rollers are arranged one-to-one in the first direction.

[0036] For ease of explanation, let's assume that the two second conveyor belts 21 in the same second conveying mechanism 2 are second conveyor belt 21a and second conveyor belt 21b. Second conveyor belt 21a is driven by multiple third rollers 222; that is, when one third roller 222 rotates, the other third rollers 222 will also rotate under the action of second conveyor belt 21a. The multiple third rollers 222 support second conveyor belt 21a, allowing it to maintain a preset shape. Second conveyor belt 21b is driven by multiple fourth rollers; that is, when one fourth roller rotates, the other fourth rollers will also rotate under the action of second conveyor belt 21b. The multiple fourth rollers support second conveyor belt 21b, allowing it to maintain a preset shape.

[0037] The second drive member 221 is used to drive at least one of the plurality of third rollers 222 and the plurality of fourth rollers to rotate. The second drive assembly 22 also includes a second connecting shaft 223 connecting the corresponding third rollers 222 and the fourth rollers. As described above, the plurality of third rollers 222 will rotate simultaneously under the action of the second conveyor belt 21a, and the plurality of fourth rollers will rotate simultaneously under the action of the second conveyor belt 21b. In this case, the corresponding third rollers 222 and the fourth rollers are connected by the second connecting shaft 223, so that the plurality of third rollers 222 and the plurality of fourth rollers can rotate simultaneously. Thus, the second drive member 221 only needs to drive the rotation of one of the plurality of third rollers 222 and the plurality of fourth rollers to drive the plurality of third rollers 222 and the plurality of fourth rollers to rotate.

[0038] With the above configuration, one second drive unit 221 can drive two second conveyor belts 21 to rotate through multiple third rollers 222 and multiple fourth rollers, ensuring that the two second conveyor belts 21 can rotate synchronously, and reducing the number of drive units required, thereby reducing the cost and control difficulty of the reversing conveyor device 10.

[0039] In the reversing conveying device 10 provided in this embodiment, two second conveying mechanisms 2 are arranged at intervals along the first direction. Multiple products received by the first conveying mechanism 1 of the reversing conveying device 10 along the first direction can be sent out from the two second conveying mechanisms 2 along the second direction, that is, the reversing conveying device 10 can convert one path of battery cell 200 input along the first direction into two paths of battery cell 200 sent out along the second direction, so as to meet the actual conveying requirements of the battery cell 200.

[0040] The reversing conveying device 10 also includes a lifting drive assembly 3 connected to the first conveying mechanism 1. The lifting drive assembly 3 is used to drive the first conveying mechanism 1 to move relative to the two second conveying mechanisms 2 in a third direction.

[0041] With the two second conveyor mechanisms 2 fixed, the lifting drive assembly 3 drives the first conveyor mechanism 1 to move in a third direction, so that the first conveyor belt 11 and the second conveyor belt 21 can move relative to each other in the third direction. The lifting drive assembly 3 is connected to the first conveyor mechanism 1 because the two second conveyor mechanisms 2 are relatively heavy in the reversing conveyor device 10. Therefore, keeping the two second conveyor mechanisms 2 fixed while driving the first conveyor mechanism 1 to move can reduce the power output required by the lifting drive assembly 3 and also save energy.

[0042] Of course, in other embodiments, it is also feasible to keep the first conveying mechanism 1 fixed and connect the lifting drive assembly 3 to the two second conveying mechanisms 2 to drive the two second conveying mechanisms 2 to move in a third direction. In the reversing conveying device 10, the number of second conveying mechanisms 2 is not limited to two.

[0043] The first driving member 121 and the first connecting shaft 123 are located between the two second conveying mechanisms 2 in the first direction. In this way, the structure of the reversing conveying device 10 is more symmetrical and compact, and the space utilization of the reversing conveying device 10 is optimized.

[0044] Combination Figure 8-11 As shown, this embodiment also provides a battery cell conveying unit 100, which includes the aforementioned reversing conveying device 10. The reversing conveying device 10 can change the conveying direction of the battery cell 200, so that the battery cell conveying unit 100 can convey the battery cell 200 along a more complex path, thereby adapting to the production requirements of the battery cell 200.

[0045] Two reversing conveying devices 10 are provided. The cell conveying unit 100 also includes a first conveying line 20, which is located between the two reversing conveying devices 10. The two reversing conveying devices 10 are designated as a first reversing conveying device 10a and a second reversing conveying device 10b. After the cell 200 changes its conveying direction via the first reversing conveying device 10a, it can travel via the first conveying line 20 to the second reversing conveying device 10b. The second reversing conveying device 10b can then change the conveying direction of the cell 200 again. In this way, the cell conveying unit 100 can change the conveying path of the cell 200 multiple times to meet actual production needs.

[0046] Specifically, two reversing conveying devices 10 are arranged at intervals along the second direction, the first conveying line 20 conveys the battery cell 200 along the second direction, and the battery cell conveying unit 100 also includes a third conveying line 22 and a fourth conveying line 23 conveying the battery cell 200 along the first direction. The third conveying line 22 is located downstream of the first reversing conveying device 10a on the conveying path of the battery cell 200, and the fourth conveying line 23 is located downstream of the second reversing conveying device 10b on the conveying path of the battery cell 200.

[0047] With the above configuration, the first reversing conveyor 10a can split the received multiple battery cells 200 into two output paths. One path of battery cells 200 moves along the first direction to the third conveyor line 22, while the other path of battery cells 200 moves along the first conveyor line 20 along the second direction to the second reversing conveyor 10b. Then, after changing the conveying direction on the second reversing conveyor 10b, they move along the first direction to the fourth conveyor line 23. The third conveyor line 22 and the fourth conveyor line 23 are used to convey the battery cells 200 to other equipment.

[0048] The cell conveying unit 100 also includes a second conveying line 21 located upstream of the reversing conveying device 10 in the cell conveying direction, and a buffer mechanism 30 disposed at the second conveying line 21. The buffer mechanism 30 is used to receive multiple cells 200 conveyed by the second conveying line 21 and to place the received multiple cells 200 into the second conveying line 21.

[0049] The cell conveying unit 100 receives cells 200 from the front-end equipment and conveys the received cells 200 to the back-end equipment. When the processing speeds of the front-end and back-end equipment for cells 200 are inconsistent, the buffer mechanism 30 can ensure that the front-end or back-end equipment does not stop, thereby ensuring the production efficiency of cells 200.

[0050] Specifically, when the speed at which the front-end equipment processes the battery cell 200 is greater than the speed at which the back-end equipment processes the battery cell 200, the number of battery cells 200 received by the battery cell conveying unit 100 will be greater than the number of battery cells 200 it outputs to the back-end equipment. At this time, the buffer mechanism 30 can store the extra battery cells 200, thereby ensuring that the front-end equipment can work continuously.

[0051] It is conceivable that when the speed at which the downstream equipment processes the battery cells 200 is greater than the speed at which the upstream equipment processes the battery cells 200, the number of battery cells 200 received by the battery cell conveying unit 100 will be less than the number of battery cells 200 it outputs to the downstream equipment. In this case, the battery cells 200 on the buffer mechanism 30 can be placed into the second conveying line 21 so that the downstream equipment can process the battery cells 200 at full capacity.

[0052] The buffer mechanism can be located at any position on the cell conveying path, and is not limited to being located on the second conveying line.

[0053] The buffer mechanism 30 includes a buffer rack 31 and a drive module 32 for driving the buffer rack 31 to move along a third direction. The buffer rack 31 includes a plurality of first slots 33 and a plurality of second slots 34 respectively disposed on both sides of the width direction of the second conveyor line 21. The plurality of first slots 33 and the plurality of second slots 34 are arranged at intervals along the third direction, and the plurality of first slots 33 and the plurality of second slots 34 are arranged one-to-one in the width direction of the second conveyor line 21.

[0054] When the battery cell 200 is conveyed by the first conveyor line 20, its two ends can be inserted into the corresponding first slot 33 and second slot 34 respectively. Then, the drive module 32 drives the buffer rack 31 to move upward, which will lift the battery cell 200 off the first conveyor line 20 so that the two ends of the next battery cell 200 can be inserted into the next set of corresponding first slots 33 and second slots 34 respectively. According to the speed at which the battery cell 200 is conveyed by the second conveyor line 21, the buffer rack 31 is driven to rise successively, and multiple battery cells 200 are then housed in the buffer rack 31.

[0055] As can be imagined, based on the speed at which the second conveyor line 21 conveys the battery cells 200, the buffer rack 31 is driven to descend sequentially, and the battery cells 200 on the buffer rack 31 can be placed one by one onto the second conveyor line 21.

[0056] It should be noted that the first conveyor line 20, the second conveyor line 21, and the third conveyor line 22 may include more than one conveyor section. For example, in this embodiment, the second conveyor line 21 consists of three conveyor sections.

[0057] The cell 200 conveying unit also includes a straightening mechanism 40, which is disposed on the cell 200 conveying path and is used to straighten the position of the cell 200 on the conveying line. In this embodiment, there are three straightening mechanisms 40, which are respectively disposed at the second conveying line 21, the third conveying line 22 and the fourth conveying line 23.

[0058] The straightening mechanism 40 includes two straightening elements 41 arranged opposite to each other and a drive mechanism for driving the two straightening elements 41 to move closer or further apart. The two straightening elements 41 are respectively located on both sides of the width direction of the conveyor line. When the two straightening elements 41 move closer together, they can contact the battery cells 200 on the conveyor line to straighten the battery cells 200 to a suitable position. After straightening is completed, the two straightening elements 41 move further apart and return to their initial position.

[0059] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0060] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
