In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] See also Figure 1-Figure 3 The utility model provides a battery cell transmission system, comprising a plurality of flower baskets 1 for storing battery cells, a feeding device 2 and a transmission device 3, wherein the feeding device 2 comprises a lifting drive member (not shown in the figure) and a yielding drive member (not shown in the figure), each lifting drive member is connected to a corresponding flower basket 1, and is used to drive the flower basket 1 to move along a first direction X, and the yielding drive member is connected to each flower basket 1, and is used to drive the flower basket 1 to selectively move toward or away from a loading position; the transmission device 3 comprises a first transmission component 31 and a transmission belt 33, and the first transmission component 31 comprises a first transmission platform 311 and a moving drive member 312 (see Figure 4 ) is used to move the first transmission platform 311 in a direction close to or away from the loading position, and the transmission belt 33 is arranged on the first transmission platform 311, and is used to transport the battery cells along the transmission direction.

[0034] In this embodiment, the first direction X is a vertical direction, two flower baskets 1 are provided, and the two flower baskets 1 are arranged side by side in the horizontal direction. The flower basket 1 is provided with a plurality of storage slots 11 along the first direction X, and a battery cell is inserted in each storage slot 11; the lifting drive is a linear motor, and the lifting drive is connected to a lifting frame 21; the giving way drive is a linear motor, and the giving way drive is connected to a giving way frame 22; the giving way drive is connected to the lifting frame 21, and is used to drive the lifting frame 21 to move in a direction perpendicular to the first direction X (that is, the horizontal direction); the transmission direction is perpendicular to the first direction X and the movement direction of the lifting frame 21; when the flower basket 1 moves to the point where the battery cell it carries is located on the input end side of the first transmission platform 311, the position of the flower basket 1 is the loading position.

[0035] Furthermore, the transmission device 3 also includes a transmission base 34, the length direction of the transmission base 34 and the length direction of the first transmission platform 311 are parallel to the transmission direction, the width of the first transmission platform 311 is smaller than the width of the battery cell, the first transmission platform 311 and the movable driving member 312 are both arranged on the transmission base 34, the movable driving member 312 is a rodless cylinder, and the output end of the rodless cylinder is connected to the first transmission platform 311.

[0036] It should be noted that the yielding driving member drives the flower basket 1 carrying the battery cells to move in a direction perpendicular to the first direction X to the loading position, and the moving driving member 312 drives the first transmission platform 311 to move in a direction close to the loading position, so that the input end of the first transmission platform 311 is inserted into the bottom of the flower basket 1 and is located below the lowest battery cell, and the transmission belt 33 contacts the battery cell at the bottom. Under the action of friction, the battery cell is transported to the output end of the first transmission platform 311 by the transmission belt 33 along the transmission direction. When the transmission belt 33 catches the battery cell, the lifting driving member controls the flower basket 1 to stop moving. When the battery cell moves on the transmission belt 33 along the transmission direction, the lifting driving member drives the flower basket 1 to descend along the first direction X, so that the battery cells in the flower basket 1 are sequentially transported to the first transmission platform 311, thereby realizing continuous transportation of the battery cells.

[0037] When all the battery cells in the flower basket 1 at the loading position are transferred to the first transfer platform 311, the mobile driving member 312 drives the first transfer platform 311 to move away from the loading position to avoid interfering with the movement of the flower basket 1. The yield driving member drives the flower basket 1 to move away from the loading position, and at the same time drives another flower basket 1 carrying battery cells to move in a direction perpendicular to the first direction X to the loading position.

[0038] In this way, a plurality of movable flower baskets 1 are provided, so that the flower baskets 1 can be quickly replaced, and the battery cells in the plurality of flower baskets 1 can be continuously transported to the first transmission platform 311, so as to avoid pausing the transmission of the battery cells due to the replacement of the flower baskets 1, and to achieve continuous loading; the first transmission platform 311 can provide good support for the transmission belt 33, and the mobile driving member 312 drives the input end of the first transmission platform 311 to be inserted into the bottom of the flower basket 1, and the flower basket 1 is gradually lowered under the action of the lifting driving member, so that the battery cells on the flower basket 1 can contact with the transmission belt 33 in turn, and be orderly transmitted to the first transmission platform 311, which replaces the step of the robot repeatedly extracting the battery cells from the flower basket 1, and improves the transmission efficiency of the battery cells.

[0039] It can be understood that the lifting drive member and the yielding drive member can also be a cylinder, and the moving drive member 312 can also be a linear motor. The specific structures of the lifting drive member, the yielding drive member and the moving drive member 312 can be adjusted according to actual needs, and are not limited to linear motors and cylinders. They can realize linear driving of the flower basket 1, the lifting frame 21, and the first transmission platform 311, and no excessive enumeration is made here; the yielding drive member can simultaneously drive multiple flower baskets 1 to move in the same direction, and can also be connected to the flower baskets 1 one by one, so that multiple flower baskets 1 can move freely, and can realize moving the empty flower basket 1 away from the loading position and moving the flower basket 1 carrying the battery cells toward the loading position.

[0040] See also Figure 1 In some embodiments, a slide rail (not shown) is disposed on the top surface of the transmission base 34 , the length direction of the slide rail is parallel to the transmission direction, and the first transmission platform 311 is disposed on the slide rail.

[0041] In this way, the first transmission platform 311 moves along the length direction of the slide rail, which can reduce the deviation of the first transmission platform 311 when being driven by the moving driving member 312, so that the input end of the first transmission platform 311 can stably move to the bottom of the flower basket 1, thereby improving the transmission efficiency of the battery cells.

[0042] See also Figure 5 In some embodiments, the flower basket 1 is detachably connected to the outer frame 12, and the flower basket 1 is provided with a positioning hole (not shown in the figure). The feeding device 2 also includes a positioning assembly 23, and the positioning assembly 23 includes a positioning rod 231 and a positioning driving member 232. The positioning driving member 232 is connected to the positioning rod 231, and is used to drive the positioning rod 231 to selectively extend into the positioning hole, so as to limit the relative position of the outer frame 12 and the flower basket 1.

[0043] In this embodiment, each flower basket 1 is detachably connected to an outer frame 12, the length direction of the outer frame 12 is parallel to the first direction X, the outer frame 12 is fixedly connected to the lifting frame 21, the positioning drive member 232 is a cylinder, the fixed end of the positioning drive member 232 is fixedly connected to the outer frame 12, the output end of the positioning drive member 232 is fixedly connected to one end of the positioning rod 231, the end of the positioning rod 231 away from the positioning drive member 232 passes through the outer frame 12 and is arranged toward the top surface of the flower basket 1, and the top surface of the flower basket 1 is provided with a positioning hole adapted to the positioning rod 231.

[0044] In this way, the positioning drive member 232 drives the positioning rod 231 to move toward the direction close to the flower basket 1, and the positioning rod 231 is inserted into the positioning hole toward one end of the flower basket 1, which can limit the flower basket 1 and enable the flower basket 1 to be stably installed on the lifting frame 21, thereby preventing the flower basket 1 from being offset or falling off during the transmission process.

[0045] It is understandable that the outer frame 12 can also be detachably connected to the lifting frame 21, and the connection method between the outer frame 12 and the lifting frame 21 can be adjusted according to actual needs, which will not be described in detail here.

[0046] See also Figure 1 and Figure 2 In some embodiments, the transmission device 3 also includes a second transmission component 32, the second transmission component 32 includes a second transmission platform 321, the second transmission platform 321 is fixedly arranged relative to the loading position, and the transmission belt 33 is arranged on the second transmission platform 321, and is used to transport the battery cells output from the first transmission platform 311 along the transmission direction.

[0047] In this embodiment, the length direction of the second transmission platform 321 is parallel to the length direction of the first transmission platform 311. The second transmission platform 321 is arranged on the output end side of the first transmission platform 311. The second transmission platform 321 is fixedly arranged on the transmission base 34 to receive the battery cells output from the first transmission platform 311.

[0048] In this way, by setting up a movable first transmission platform 311 and a fixed second transmission platform 321, the transmission path of the battery cells can be extended, so that the transmission belt 33 can transport multiple battery cells at the same time, improve the transmission efficiency of the battery cells, and facilitate the continuous transmission of multiple battery cells; the first transmission platform 311 and the second transmission platform 321 can support the transmission belt 33 to stably transmit the battery cells, avoid the battery cells from shifting or falling off during transportation, and improve the transmission effect of the battery cells.

[0049] See also Figure 1 and Figure 2In some embodiments, the first transmission component 31 also includes a movable conveying wheel 313, which is arranged on both sides of the first transmission platform 311 and moves synchronously with the first transmission platform 311. The second transmission component 32 also includes a fixed conveying wheel 322, which is arranged on both sides of the second transmission platform 321. The movable conveying wheel 313 and the fixed conveying wheel 322 are connected by a transmission belt 33, so that when the movable conveying wheel 313 moves, the total length of the transmission belt 33 remains unchanged.

[0050] Among them, two groups of movable conveying wheels 313 are provided, one group of movable conveying wheels 313 includes two movable conveying wheels 313, one group of movable conveying wheels 313 is arranged on both sides of the input end of the first transmission platform 311, and the other group of movable conveying wheels 313 is arranged on both sides below the output end of the first transmission platform 311, and four groups of fixed conveying wheels 322 are provided, one group of fixed conveying wheels 322 includes two fixed conveying wheels 322, two groups of fixed conveying wheels 322 are arranged on both sides of one end of the transmission base 34 facing the flower basket 1 and on both sides of the end away from the flower basket 1, and the other two groups of fixed conveying wheels 322 are arranged on both sides of the input end and both sides of the output end of the second transmission platform 321, and the movable conveying wheels 313 and the fixed conveying wheels 322 on the same side are connected by transmission belts 33, and the transmission belts 33 refer to Figure 7 Winding is performed.

[0051] It should be noted that when the mobile driving member 312 drives the first transmission platform 311 to move toward or away from the loading position, the dynamic conveying wheel 313 moves synchronously with the first transmission platform 311. Since the dynamic conveying wheels 313 arranged on both sides of the input end and the output end of the first transmission platform 311 move with the first transmission platform 311, the transmission belt 33 can always be connected to the first transmission platform 311 and the second transmission platform 321 without changing its total length, and the battery cells can be transported from the first transmission platform 311 to the second transmission platform 321.

[0052] In this way, the cooperation between the multiple movable conveying wheels 313 and the multiple fixed conveying wheels 322 can increase the contact area with the transmission belt 33, that is, it can increase the maximum static friction between the transmission belt 33, avoid slipping between the transmission belt 33 and the movable conveying wheels 313 or the fixed conveying wheels 322, and improve the transmission effect of the battery cells.

[0053] Furthermore, the transmission device 3 also includes a transmission drive 35, which is a motor. The output end of the transmission drive 35 is connected to the fixed conveying wheel 322 to drive the fixed conveying wheel 322 to rotate, drive the transmission belt 33 to move, and move the battery cell along the transmission direction. In this way, the transmission of the battery cell can be achieved by setting a transmission drive 35, saving equipment costs.

[0054] See also Figure 1 and Figure 2 In some embodiments, a blocking column 323 is provided at the output end of the second transmission platform 321 to prevent the battery cells from continuing to move along the transmission direction. Furthermore, the battery cell transmission system further includes a handling hand 4, which is provided at the output end of the second transmission platform 321 and is used to carry the battery cells output from the second transmission platform 321.

[0055] In this embodiment, one second transport platform 321 is provided with two blocking columns 323, which are cylindrical structures. The two blocking columns 323 are arranged on both sides of the axis of the second transport platform 321 along its length direction, and the distance between the two blocking columns 323 is smaller than the width of the battery cell.

[0056] Thus, when the battery cells are transported to the output end of the second transport platform 321, the blocking column 323 can prevent the battery cells from continuing to move, thereby preventing the battery cells from falling off the second transport platform 321, making it easier for staff to remove the battery cells from the second transport platform 321 and improving handling efficiency.

[0057] It is understandable that the outer wall of the blocking column 323 may also be provided with a buffer member (not shown in the figure) made of elastic material to reduce the friction between the battery cell and the blocking column 323 .

[0058] Furthermore, the battery cell conveying system may also include a control module, and a proximity sensor (not shown in the figure) may be set on the blocking column 323. The proximity sensor and the transmission drive 35 are both connected to the control module. When the proximity sensor senses a battery cell moving near the blocking column 323, the proximity sensor can send a signal to the control module, so that the control module controls the transmission drive 35 to stop working and stop the transmission of the battery cell, thereby avoiding wear caused by long-term contact between the battery cell and the blocking column 323.

[0059] See also Figure 1 In some embodiments, each flower basket 1 is provided with a plurality of columns of storage slots 11 for storing battery cells along the first direction X, the number of the first transmission platforms 311 is equal to the number of columns of storage slots 11 on one flower basket 1, and each first transmission platform 311 is provided in a one-to-one correspondence with each column of storage slots 11.

[0060] In this embodiment, each flower basket 1 is provided with two rows of storage slots 11, and two first transmission platforms 311 and second transmission platforms 321 are correspondingly provided. The fixed conveying wheels 322 of the two first transmission platforms 311 are connected by a coupling 37, which is used to enable the transmission driving member 35 to drive the fixed conveying wheels 322 on the two first transmission platforms 311 to rotate, so that the transmission belts 33 on the two first transmission platforms 311 can both transmit battery cells.

[0061] Thus, by providing the first transmission platforms 311 with the same number as the number of storage slots 11, the cells on the two storage slots 11 can be simultaneously transported to the first transmission platforms 311, thereby improving the transmission efficiency of the cells and shortening the transmission time.

[0062] It is understandable that the number of storage slots 11 on the same flower basket 1 can be adjusted according to actual needs and is not limited to two, and will not be listed in detail here.

[0063] See also Figure 1 and Figure 4 In some embodiments, the first transmission component 31 also includes a driving plate 314, which is fixedly connected to each first transmission platform 311, and a mobile driving member 312 is connected to the driving plate 314, and is used to drive the driving plate 314 to drive the first transmission platform 311 to move in a direction close to or away from the loading position.

[0064] In this embodiment, the length direction of the driving plate 314 is parallel to the transmission direction. Two connecting rings 3141 are connected to the top surface of the driving plate 314. The two connecting rings 3141 are fixedly connected to the two first transmission platforms 311 respectively, so that when the mobile driving member 312 drives the driving plate 314 to move in a direction close to or away from the loading position, the two connecting rings 3141 respectively drive the two first transmission platforms 311 to move synchronously.

[0065] In this way, the two first transmission platforms 311 can be driven to move synchronously by one moving driving member 312, which saves equipment cost and enables the battery cells in the two rows of storage slots 11 to be transmitted synchronously, making it easier to collect the output single battery cells and improving the battery cell transportation efficiency.

[0066] See also Figure 4 In some embodiments, the input end of the first transmission platform 311 is provided with a sensing element 36 for sensing the transmission state of the battery slice on the first transmission platform 311. Further, the sensing element 36 is a proximity sensor, which is in communication with the lifting drive element and is used to control the flower basket 1 (see FIG. 1 ) at the loading position according to the transportation state of the battery slice on the first transmission platform 311. Figure 1 ) movement in a first direction X.

[0067] In this embodiment, a proximity sensor is provided at the input end of each first transmission platform 311 , and the proximity sensor and the lifting drive are both connected to the control module.

[0068] In this way, when the sensing element 36 senses that the battery cells are transported to the input end of the first transmission platform 311, the sensing element 36 sends a signal to the control module, so that the control module controls the lifting drive element to stop working, so that the flower basket 1 located at the loading position stops descending, so as to avoid interference with the battery cells just transported to the first transmission platform 311. When the sensing element 36 senses that there are no battery cells on the input end of the first transmission platform 311, the lifting drive element drives the flower basket 1 to continue to descend, so that the battery cells at the bottom are transported to the input end of the first transmission platform 311, thereby improving the transmission efficiency of the battery cells and the safety during the transmission process, so that the battery cells can be orderly and coherently transmitted from the flower basket 1 to the first transmission platform 311.

[0069] It is understandable that the sensing element 36 may also be a pressure sensor or other structure. The specific structure and installation position of the sensing element 36 may be adjusted according to actual needs, and it is sufficient to detect the transportation status of the battery cell on the first transmission platform 311. No further details are given here.

[0070] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
