[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0035] like Figures 1 to 9 As shown, the battery cell feeding device provided by this utility model includes a feeding and conveying assembly 101, a feeding box 102, and a feeding assembly 104.

[0036] The feeding and conveying assembly 101 is used to transport the battery cells to be processed to the processing area. The feeding box 102 is used to place the battery cells to be processed, and the feeding assembly 104 is used to move the battery cells to be processed in the feeding box 102 to the feeding and conveying assembly 101.

[0037] In some embodiments, the cell loading device further includes a first track 103 extending along the arrangement direction of the loading transfer assembly 101 and the loading box 102. The loading assembly 104 is slidably mounted on the first track 103 and reciprocates along the first track 103 between the loading transfer assembly 101 and the loading box 102, thereby transferring the cells to be processed in the loading box 102 to the loading transfer assembly 101 for subsequent cell processing. Alternatively, the first track 103 can be omitted, and the cells to be processed in the loading box 102 can be moved to the loading transfer assembly 101 by rotating the loading assembly 104.

[0038] For ease of description, when the feeding component 104 moves along the first track 103 to directly above the feeding conveying component 101, the position of the feeding component 104 at this time is defined as the feeding position. When the feeding component 104 moves along the first track 103 to directly above the feeding box 102, the position of the feeding component 104 at this time is defined as the picking position.

[0039] The feeding and conveying assembly 101 includes a support frame 101a, a conveyor belt 101b connected to the support frame 101a, and a drive motor 101c for moving the conveyor belt 101b.

[0040] Specifically, one end of the support frame 101a is provided with a pair of driving wheels, and the other end is provided with a pair of driven wheels. The conveyor belt 101b is connected between the driving wheels and the driven wheels. A drive shaft is connected between the pair of driving wheels, and the output end of the drive motor 101c is connected to the drive shaft via a belt. The operation of the drive motor 101c drives the drive shaft to rotate, and the rotation of the drive shaft drives the driving wheels to rotate, thereby driving the conveyor belt 101b to move, so as to transport the battery cells placed on the conveyor belt 101b by the feeding assembly 104.

[0041] The feeding and conveying assembly 101 also includes a fifth photoelectric sensor 101d located at the starting end of the conveyor belt 101b and a sixth photoelectric sensor 101e disposed at an interval from the fifth photoelectric sensor 101d.

[0042] The fifth photoelectric sensor 101d is located below the conveyor belt 101b and directly opposite the loading position of the loading assembly 104. Thus, when the loading assembly 104 places the battery cell to be processed onto the conveyor belt 101b, the fifth photoelectric sensor 101d can detect the battery cell, thereby controlling the drive motor 101c to start and transport the battery cell. In this embodiment, the fifth photoelectric sensor 101d is fixed to the support frame 101a.

[0043] The sixth photoelectric sensor 101e is located downstream of the fifth sensor 101d. The sixth photoelectric sensor 101e includes an ultrasonic transmitter and an ultrasonic receiver located above and below the conveyor belt 101b, respectively. Normally, when a battery cell is transported via the conveyor belt 101b to the location of the sixth photoelectric sensor 101e, the ultrasonic transmitter emits an ultrasonic beam towards the battery cell. The ultrasonic beam causes the battery cell to vibrate, generating a corresponding sound wave on the other side of the battery cell, which is then received by the ultrasonic receiver. If the battery cells transported to the location of the sixth photoelectric sensor 101e are stacked, the ultrasonic beam becomes very weak when passing through multiple battery cells and cannot be received by the ultrasonic receiver, thus enabling the detection of stacking.

[0044] In this embodiment, the sixth photoelectric sensor 101e is mounted on a fixing frame 101f, and the fixing frame 101f is located at the end of the support frame 101a away from the fifth photoelectric sensor 101d.

[0045] The loading box 102 and the loading conveyor assembly 101 are spaced apart. Preferably, the arrangement direction of the loading box 102 and the loading conveyor assembly 101 is perpendicular to the conveying direction of the battery cells. Simultaneously, the extending direction of the first track 103 is perpendicular to the extending direction of the conveyor belt 101b.

[0046] The loading box 102 includes a base plate 102a, several limiting plates 102b fixed around the base plate 102a, a support plate 102c located above the base plate 102a, and a lifting component 102d for driving the support plate 102c to move along the height direction.

[0047] The limiting plate 102b is disposed perpendicular to the base plate 102a, and a plurality of the limiting plates 102b enclose a storage area for placing the battery cells to prevent the stacked battery cells from tipping over. In this embodiment, two limiting plates 102b are provided on each side of the base plate 102a, and the two limiting plates 102b are spaced apart.

[0048] The battery cells are stacked on the support plate 102c. The lifting component 102d moves the support plate 102c and the battery cells on it along the height direction so that the feeding component 104 can pick up the battery cells. After the feeding component 104 removes the top battery cell, the lifting component 102d raises the support plate 102c to a certain height, the same height as the thickness of the battery cell, so that the next battery cell rises to the position of the original top battery cell. That is, the distance between the feeding component 104 and the top battery cell is the same each time the feeding component 104 moves to the picking position.

[0049] The base plate 102a has a first through hole 102a-1, and the lifting member 102d is located below the base plate 102a. The output end of the lifting member 102d passes through the first through hole 102a-1 and is connected to the support plate 102c.

[0050] The lifting component 102d is an electric cylinder, and the lifting shaft of the electric cylinder passes through the first through hole 102a-1 and is connected to the support plate 102c. When the support plate 102c needs to rise or fall, the electric cylinder is activated to drive the support plate 102c to rise or fall. Of course, the lifting component 102d can also adopt other structures capable of driving the support plate 102c to rise and fall.

[0051] The feeding box 102 also includes a first photoelectric sensor 102e located below the base plate 102a. The support plate 102c has a second through hole 102c-1, which partially overlaps with the first through hole 102a-1. The first photoelectric sensor 102e emits light along the height direction, passing through the first through hole 102a-1 and the second through hole 102c-1.

[0052] The first photoelectric sensor 102e is used to detect whether there are still unprocessed battery cells on the carrier plate 102c. When there are still unprocessed battery cells on the carrier plate 102c, the light emitted by the first photoelectric sensor 102e passes through the first through hole 102a-1 and the second through hole 102c-1 to the battery cell, and is reflected back to the first photoelectric sensor 102e, indicating that there are still unprocessed battery cells on the carrier plate 102c. When there are no unprocessed battery cells on the carrier plate 102c, the light emitted by the first photoelectric sensor 102e passes through the first through hole 102a-1 and the second through hole 102c-1 and is emitted directly. The first photoelectric sensor 102e does not receive the reflected light, indicating that there are no unprocessed battery cells on the carrier plate 102c, and can remind the operator to perform patching.

[0053] The feeding box 102 also includes a plurality of air knives 102f located outside the limiting plate 102b, wherein the air outlet direction of the air knives 102f forms an angle with the height direction. The air knives 102f are used to blow air onto the stacked battery cells, thereby separating the battery cells and preventing them from sticking together, so that the feeding assembly 104 can pick up multiple battery cells at a time.

[0054] The air knife 102f includes a fixed plate 102f-1 and an air-blowing block 102f-2 movably mounted on the fixed plate 102f-1 along the height direction. The fixed plate 102f-1 is arranged parallel to the limiting plate 102b, and the fixed plate 102f-1 is provided with a sliding groove extending along the height direction. The air-blowing block 102f-2 is installed in the sliding groove by fixing bolts. The height of the air-blowing block 102f-2 can be adjusted by moving the air-blowing block 102f-2 along the sliding groove and then tightening the fixing bolts.

[0055] The height of the air blowing block 102f-2 is adjusted so that the air blowing port is aimed at the uppermost battery cell. The gas blown out by the air blowing block 102f-2 can be blown towards the battery cell through the gap between the limiting plates 102b. By blowing air onto the battery cell, the uppermost battery cell is lifted and separated from the other battery cells, and then the feeding assembly 104 picks up the battery cell, thereby effectively preventing the feeding assembly 104 from picking up multiple battery cells at once.

[0056] In this embodiment, four air blades 102f are provided, arranged in pairs on opposite sides of the support plate 102c. Two air blades 102f are arranged diagonally along the support plate 102c, and the distance between two air blades 102f on the same side is greater than half the length of the support plate 102c along the arrangement direction of the air blades 102f. This facilitates the separation of battery cells and keeps the separated battery cells stable, reducing the probability of stacked cells and battery cells being blown away. Preferably, the air blowing block 102f-2 blows air upwards at an angle.

[0057] The feeding box 102 also includes a second photoelectric sensor 102g and a third photoelectric sensor 102h located above the base plate 102a. The second photoelectric sensor 102g and the third photoelectric sensor 102h emit light in a horizontal direction. The height of the second photoelectric sensor 102g is greater than the height of the air knife 102f, used to detect the battery cells separated by the air knife 102f. The height of the third photoelectric sensor 102h is less than the height of the second photoelectric sensor 102g, used to detect the battery cells that have risen to the picking position.

[0058] When the uppermost solar cell on the support plate 102c rises to the material handling position, the light emitted by the third photoelectric sensor 102h is reflected back to the third photoelectric sensor 102h by the uppermost solar cell. After the uppermost solar cell is removed by the feeding assembly 104, the light emitted by the third photoelectric sensor 102h is no longer blocked by the solar cell and reflected back. Then, the lifting component 102d drives the support plate 102c to rise, and the solar cells on the support plate 102c rise synchronously until the uppermost solar cell once again blocks and reflects the light emitted by the third photoelectric sensor 102h, at which point the lifting component 102d stops.

[0059] The third photoelectric sensor 102h ensures that the picking height of the battery cell remains constant, facilitating the separation of the battery cell by the air knife 102f. Each time the topmost battery cell is removed by the feeding assembly 104, the next battery cell will rise to the same height as the original topmost battery cell under the action of the lifting component 102d. This ensures that the distance between the feeding assembly 104 and the topmost battery cell is the same each time the feeding assembly 104 moves to the picking position, facilitating the picking process.

[0060] The height of the second photoelectric sensor 102g is greater than the height of the air knife 102f, and the second photoelectric sensor 102g is used to detect the battery cells separated by the air knife 102f.

[0061] In one scenario, the height of the second photoelectric sensor 102g is the same as the height of the battery cell after it has been normally blown up by the air knife 102f. When the third photoelectric sensor 102h detects that the battery cell has reached the picking position, the air knife 102f is activated to blow air onto the battery cell, lifting the topmost battery cell and separating it from the others. When the light emitted by the second photoelectric sensor 102g is blocked by the battery cell, it indicates that the battery cell at the picking position has been normally blown up, and it can then be picked up by the feeding assembly 104. When the light emitted by the second photoelectric sensor 102g is not blocked by the battery cell, it indicates that the battery cell has been blown away.

[0062] In another scenario, the height of the second photoelectric sensor 102g is greater than the height of the battery cell after it has been normally blown up by the air knife 102f. When the third photoelectric sensor 102h detects that the battery cell has reached the picking position, the air knife 102f is activated to blow air onto the battery cell, lifting the topmost battery cell and separating it from the others. When the light emitted by the second photoelectric sensor 102g is not blocked by the battery cell, it indicates that the battery cell at the picking position has been normally blown up, and it can then be picked up by the feeding assembly 104. When the light emitted by the second photoelectric sensor 102g is blocked by the battery cell, it indicates that the battery cell has been blown away.

[0063] When a battery cell is detected being blown away, an audible and visual alarm can alert the operator. Thus, the second photoelectric sensor 102g can promptly detect battery cells blown away by the air blade 102f, allowing the operator to inspect the air blade 102f and determine if there is any abnormality in the air blade 102f that caused the battery cell to be blown away.

[0064] The first track 103 extends along the arrangement direction of the feeding and conveying assembly 101 and the feeding box 102. The feeding assembly 104 reciprocates between the feeding and conveying assembly 101 and the feeding box 102 along the first track 103. The extension direction of the first track 103 is perpendicular to the transmission direction of the battery cells.

[0065] The first track 103 is equipped with positioning sensors at the material picking position and the material loading position. When the material loading component 104 moves to the material picking position or the material loading position, the positioning sensors can detect that the material loading component 104 has reached the designated position, thereby stopping its movement to perform the material picking and loading operations. The positioning sensors may also be photoelectric sensors.

[0066] The feeding assembly 104 includes a feeding suction cup 104a, a first driving member 104b for driving the feeding suction cup 104a to move along the first track 103, and a fourth photoelectric sensor 104c located on the feeding suction cup 104a.

[0067] Under the action of the first driving member 104b, the feeding suction cup 104a is driven to reciprocate between the picking position and the feeding position along the first track 103. When the feeding suction cup 104a reaches the picking position, it picks up the battery cells in the feeding box 102, and then moves to the feeding position to place the picked-up battery cells on the feeding transfer assembly 101.

[0068] The bottom surface of the feeding suction cup 104a is provided with a groove. When the feeding suction cup 104a moves above the feeding box 102, air is extracted from the groove to create a negative pressure at the groove location to suck up the battery cells. When the feeding suction cup 104a moves above the feeding transfer assembly 101, the negative pressure environment in the groove is removed, allowing the battery cells to fall onto the feeding transfer assembly 101.

[0069] The first driving member 104b drives the loading suction cup 104a to move along the first track 103. A driving screw can be provided on the first track 103, and a nut threaded onto the driving screw can be provided on the loading suction cup 104a. The first driving member 104b drives the driving screw to rotate, thereby causing the loading suction cup 104a to move along the first track 103. Alternatively, a rack can be provided on the first track 103, and a gear meshing with the rack can be provided on the loading suction cup 104a. The first driving member 104b drives the gear to rotate, thereby causing the loading suction cup 104a to move along the first track 103. Of course, this application is not limited to these methods; any method that enables the loading suction cup 104a to move along the first track 103 is acceptable.

[0070] The fourth photoelectric sensor 104c is used to detect the battery cells picked up by the feeding suction cup 104a. After the feeding suction cup 104a picks up the battery cells, the light emitted by the fourth photoelectric sensor 104c is blocked and reflected by the battery cells.

[0071] The feeding assembly 104 further includes a second driving member 104d for moving the feeding suction cup 104a along the height direction. The movement of the feeding suction cup 104a along the height direction serves two purposes: firstly, after picking up the battery cells, the feeding suction cup 104a can be shaken to prevent the battery cells from sticking together and to dislodge any stuck battery cells; secondly, the feeding suction cup 104a can be lowered to place the battery cells onto the feeding and conveying assembly 101. The second driving member 104d can be a cylinder.

[0072] The following is a detailed description of the feeding process of this device:

[0073] First, the support plate 102c is lowered to its lowest position, and the neatly stacked battery cells are placed on the support plate 102c. The battery cells are located within the storage area enclosed by several limiting plates 102b. At this time, the uppermost battery cell blocks the light emitted by the third photoelectric sensor 102h.

[0074] The first driving component 104b is activated, which moves the feeding suction cup 104a to the material picking position. The air knife 102f is turned on to blow up the uppermost battery cell, and the feeding suction cup 104a picks up the battery cell. The fourth photoelectric sensor 104c detects the battery cell.

[0075] The air blade 102f is turned off. The lifting component 102d is activated, which drives the support plate 102c to rise until the uppermost battery cell once again blocks and reflects the light emitted by the third photoelectric sensor 102h.

[0076] Re-activate the first drive unit 104b to move the feeding suction cup 104a to the feeding position, lower the feeding suction cup 104a and place the battery cell on the feeding transfer assembly 101.

[0077] The fifth sensor 101d detects the battery cell, and the drive motor 101c is activated to transport the battery cell. The battery cell is transported to the location of the sixth photoelectric sensor 101e, where it is detected that the cells are stacked. If no cells are stacked, the battery cell is transported to the processing area; if cells are stacked, an alarm is issued, the stacking is resolved, and the battery cell is then transported to the processing area.

[0078] This process is repeated until all the cells to be processed have been loaded.

[0079] This invention uses the feeding assembly 104 to transfer the battery cells in the feeding box 102 to the feeding and conveying assembly 101, thereby achieving automated feeding; and uses the liftable and adjustable support plate 102c to raise the battery cells to a specific position so that the feeding assembly 104 can pick them up; and uses the second photoelectric sensor 102g to detect the battery cells separated by the air knife 102f, so that the blown-away battery cells can be detected in time.

[0080] 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.

[0081] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
