Description

Technical Field

[0001] The utility model relates to the field of production and manufacturing of solar cells, and particularly relates to a glue coating device for battery wafers. Background Art

[0002] In the production process of photovoltaic cells, there is a process of edge sealing for the cells. For example, in the process of preparing grid lines on the cells by electroplating, it is necessary to pre-coat glue on the side surfaces of the cells to form a protective layer to protect the side surfaces of the cells from electroplating. For conventional rectangular cells, it is necessary to coat glue on the upper, lower, and side surfaces of the four edges and chamfer and other edge structures in the length and width directions respectively, and this process is also called the edge wrapping treatment process of the cells.

[0003] Most of the existing glue coating devices for battery wafers are single-piece loading and single-piece transfer, resulting in low efficiency. For example, the glue coating device for battery wafers disclosed in the patent document CN220781055U is single-piece loading, transfer, and conveying, with a long waiting time and low production efficiency.

[0004] Another example is the glue coating device for battery wafers disclosed in the patent document CN221132955U.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0066] To facilitate the description and understanding of the specific structure of the battery cell gluing device, a three-dimensional space coordinate system is constructed in the battery cell gluing equipment in this embodiment, where the first direction X, the second direction Y, and the up-and-down (vertical) direction Z are perpendicular to each other in pairs, and the first direction X and the second direction Y extend along the horizontal direction respectively. The first direction X is defined as the transmission direction of the battery cell in the battery cell. In some embodiments, the first direction X and the second direction Y and the up-and-down direction Z may not be strictly perpendicular, but intersect at an angle close to 90°.

[0067] The battery cell gluing equipment of this embodiment is used for gluing the two pairs of side edges and four chamfers of the rectangular battery cell 1. The rectangular battery cell 1 has two opposite rectangular surfaces, and there are two opposite long side edges, two opposite short side edges, and four chamfers between the four adjacent side edges between the two surfaces. The two pairs of side edges are a pair of short side edges and a pair of long side edges. Gluing the battery cell 1 specifically refers to gluing the side edges, chamfers, and the four peripheral edges and the upper and lower surfaces close to the edges of the two surfaces of the battery cell 1.

[0068] As Figures 1-13 shown, the battery cell gluing equipment of this embodiment includes a workbench 12 and a feeding device 2, a loading device 5, a first gluing device 6, a third conveying mechanism 10, a first rotating device 71, a second gluing device 8, a second rotating device 72, and a discharging device 9 that are sequentially arranged on the workbench 12 along the first direction. Among them, a rectifying device 3 and a first vision positioning mechanism 4 are also arranged on the conveying path of the feeding device 2, and a second vision positioning mechanism 13 is also arranged on the rotating path of the first rotating device 71. The functions of each device are basically as follows:

[0069] The feeding device 2 is used to realize the continuous feeding of the battery cell 1;

[0070] The rectifying device 3 is used to rectify the position of the battery cell 1 on the transmission path of the feeding device 2 to ensure that the position of the battery cell 1 remains consistent when the loading device 5 adsorbs the battery cell 1;

[0071] The first vision positioning mechanism 4 is used to obtain the image information of the rectified battery cell 1;

[0072] The feeding device 5 is used to convey the battery cells 1 to the first gluing device 6, and adjust the position and angle of the battery cells 1 during feeding in cooperation with the image information obtained by the first vision positioning mechanism 4;

[0073] The first gluing device 6 is used to apply glue to the first pair of side edges and chamfers of the battery cells 1; the first pair of side edges in this embodiment are the short sides of the battery cells 1;

[0074] The third conveying mechanism 10 is used to receive the battery cells 1 conveyed by the first gluing device 6 and wait for the first rotating device 71 to pick them up;

[0075] The second vision positioning mechanism 13 is used to obtain the image information of the battery cells 1;

[0076] The first rotating device 71 is used to transfer the battery cells 1 from the third conveying mechanism 10 to the second gluing device 8, and adjust the position and angle of the battery cells 1 during transfer in cooperation with the image information obtained by the second vision positioning mechanism 13;

[0077] The second gluing device 8 is used to apply glue to the second pair of side edges of the battery cells 1; the second pair of side edges in this embodiment are the long sides of the battery cells 1; when the battery cells 1 are rectangular or chamfered rectangles, the first pair of side edges are perpendicular to the second pair of side edges;

[0078] The second rotating device 72 is used to transfer the battery cells 1 coated with glue by the second gluing device 8 to the discharging device 9;

[0079] The discharging device 9 is used to discharge the glued battery cells 1.

[0080] The following describes the specific structures of each device:

[0081] The feeding device 2 includes a first conveyor belt 21 and a feeding driving mechanism 22 for driving the first conveyor belt 21 to run. The first conveyor belt 21 extends in the first direction, and the battery cells 1 are carried on the first conveyor belt 21 and are driven by the first conveyor belt 21 to pass through the alignment device 3 and the first vision positioning mechanism 4 in sequence along the first direction and then are picked up by the feeding device 5 by adsorption. An alignment station 31 corresponding to the alignment device 3 and an identification station 41 corresponding to the first vision positioning mechanism 4 are provided in the transmission direction of the feeding device 2.

[0082] The alignment device 3 aligns the position of the battery cells 1 at the alignment station 31, and is used to roughly pre-adjust the battery cells 1 with too large offset positions to facilitate the subsequent acquisition of image information by the first vision positioning mechanism 4 and the adsorption and feeding by the feeding device 5. The alignment device 3 can use alignment rods 32 provided corresponding to the edges of the first pair of side edges for alignment, and the alignment rods 32 extend in the up and down direction. Preferably, rollers are sleeved outside the alignment rods 32.

[0083] The rectified solar cell 1 is transported to the identification station 41. The first vision positioning mechanism 4 acquires the image information of the corresponding solar cell 1 and transmits it to the loading device 5. The loading device 5 receives the image information and adjusts the position of the solar cell 1 according to the image information during the loading process, so that the first pair of side edges of the adsorbed solar cell 1 are transported to the first gluing device 6 in a posture parallel to the first direction, that is, the length direction of the solar cell is parallel to the second direction at this time.

[0084] The loading device 5 includes a suction attachment 51 for acquiring the solar cell 1 and a loading drive mechanism for driving the suction attachment 51 to move. The number of suction attachments 51 on the loading device 5 corresponds to the number of first support platforms 622 on each first transfer table 621. In this embodiment, there are two. That is, the loading device 5 adsorbs two solar cells 1 at the same time and correspondingly places them on the two first support platforms 622 of a first transfer table 621, and is driven forward by the first transfer table 621, effectively improving the transfer efficiency.

[0085] The suction attachment 51 can rotate around a rotation axis extending in the vertical direction to cooperate with the image information acquired by the first vision positioning mechanism 4 to adjust the position and angle of the solar cell 1, so that the first pair of side edges of the adsorbed solar cell 1 are placed on the first support platform 622 of the first transfer table 621 in a posture parallel to the first direction.

[0086] The first gluing device 6 includes a first gluing mechanism 61 and a first transfer mechanism 62. The first transfer mechanism 62 is used to receive the solar cell 1 transmitted by the loading device 5, apply glue by the first gluing mechanism 61, and then transmit it to the third transfer mechanism 10; the first transfer mechanism 62 includes multiple groups of first transfer components for alternately transferring the solar cell 1.

[0087] Each first transfer component includes a first transfer table 621 and a first transfer drive for driving the first transfer table 621 to move. The first transfer drive includes an X-direction drive 111 for driving the first transfer table 621 to move in the first direction and a Z-direction drive 113 for driving the first transfer table 621 to move in the vertical direction. A plurality of first support platforms 622 for carrying the solar cell 1 are provided on each first transfer table 621, that is, each first transfer table 621 drives multiple solar cells 1 to move and apply glue at the same time.

[0088] Each first glue - applying mechanism 61 includes a first glue - applying member 611, a glue - applying member driver 612 for driving the glue - applying member to rotate, and a first glue - applying driving member for driving the first glue - applying member 611 to move. The first glue - applying driving member includes an X - direction driver 111 for driving the first glue - applying member 611 to move in the first direction, a Y - direction driver 112 for driving it to move in the second direction, and a Z - direction driver 113 for driving it to move in the up - and - down direction. The glue - applying member driver 612 drives the first glue - applying member 611 to rotate to apply glue to the first pair of side surfaces, chamfers, upper and lower surfaces near the edges of the corresponding side surfaces and chamfer edges of the battery cell 1 on the moving path of the battery cell 1. The first glue - applying driving members in different directions drive the glue - applying positions of the glue - applying member 611 to match battery cells 1 of different specifications.

[0089] The size of the first support platform 622 is smaller than the size of the battery cell 1 to facilitate the glue - applying member to apply glue to the edge of the battery cell 1 and avoid interference between the first support platform 622 and the glue - applying member.

[0090] The third conveying mechanism 10 includes a first conveying part 101 and a second conveying part 102. The first conveying part 101 is arranged close to the first conveying mechanism 62, and the second conveying part 102 is arranged close to the first rotating device 71. The first conveying part 101 is used to receive the battery cell 1 conveyed by the first conveying component and convey it to the second conveying part 102 for the first rotating device 71 to pick up. Preferably, the conveying speed of the first conveying part 101 is greater than that of the second conveying part 102. In this way, the front - end first conveying part 101 quickly receives and conveys the battery cell 1 coming from the first support platform 622, and the rear - end second conveying part 102 slows down to carry the battery cell 1 and waits for the first rotating device 71 to adsorb it.

[0091] The first conveying part 101 includes a first conveyor belt 1011 and a first conveying driver (not shown) for driving the first conveyor belt 1011 to operate. The first conveyor belt 1011 extends from the second conveying part 102 towards the first conveying mechanism 62. A receiving groove 6221 for accommodating the first conveyor belt 1011 is formed on the first support platform 622. The first conveyor belt 1011 is used to insert into the receiving groove 6221 when receiving the battery cell 1 conveyed from the first support platform 622.

[0092] In this embodiment, the first conveying part 101 and the second conveying part 102 are fixed on the workbench 12 through a fixing seat 103. The fixing seat 103 has an extension rod 104 extending towards the first conveying mechanism. The first conveyor belt 1011 is sleeved on the extension rod 104, and the overall thickness formed is less than the depth of the receiving groove 6221 on the first support platform 622.

[0093] The second conveying part 102 includes a second conveyor belt 1021, a second conveying driver 1022 for driving the second conveyor belt 1021 to operate, and a carrying platform 1023 located between two second conveyor belts 1021. The carrying platform 1023 is used to raise the horizontal height of the battery cell 1 on the carrying platform 1023 when the first rotating device 71 obtains the battery cell 1. The carrying platform 1023 in this embodiment can move up and down. When the battery cell 1 is conveyed by the second conveyor belt 1021, the horizontal height of the carrying platform 1023 is raised to facilitate the first rotating device 71 to grasp the battery cell at a fixed position.

[0094] A stop block 1024 is arranged on the second conveying part 102 corresponding to the carrying platform 1023, which is used to position the position of the battery cell 1 on the carrying platform 1023 after being conveyed by the second conveyor belt 1021, facilitating the first rotating device 71 to grasp it.

[0095] The distance between two first conveyor belts 1011 and the distance between two second conveyor belts 1021 need to be less than the length of the long side of the battery cell 1 to avoid contacting the glue-applying position.

[0096] The structures of the first rotating device 71 and the second rotating device 72 in this embodiment are basically the same, including a rotating base 711 and adsorption components 712 uniformly arranged at intervals on the rotating base 711. The rotating base 711 can rotate along a first rotation center line extending in the up-and-down direction. At the same time, each adsorption component 712 can rotate along a second rotation center line extending in the up-and-down direction. The first rotation center line and the second rotation center line are parallel. The rotating device includes an adjusting mechanism (not shown) for driving the adsorption component 712 to rotate along the second rotation center line.

[0097] In this embodiment, a second visual positioning mechanism 13 is arranged on the rotation path of the first rotating device 71. Its principle is basically the same as that of the first visual positioning mechanism 4. It is used to obtain the image information of the corresponding battery cell 1 and transmit it to the second rotating device 72. The second rotating device 72 receives this image information and adjusts the position and angle of the battery cell 1 according to this image information during the process of driving the movement of the battery cell 1, so that the adsorbed battery cell 1 is finally placed on the second support platform 823 with the second pair of side edges parallel to the first direction. The first visual positioning mechanism 4 and the second visual positioning mechanism 13 are preferably visual recognition cameras, such as CCD, etc.

[0098] The second glue-applying device 8 includes a second glue-applying mechanism 81 and a second conveying mechanism 82. The second conveying mechanism 82 is used to receive the battery cell 1 conveyed by the first rotating device 71, apply glue through the second glue-applying mechanism 81, and then convey it to the blanking device 9.

[0099] The structures of the second glue - applying mechanism 81 and the first glue - applying mechanism 61 are basically the same, including a second glue - applying member 811, a glue - applying member driver for driving the rotation of the glue - applying member for glue - applying, and a second glue - applying driving member for driving the movement of the second glue - applying member 811. The second glue - applying driving member includes a Z - direction driver 113 for driving the second glue - applying member 811 to move in the up - and - down direction. The second glue - applying member 811 is used for applying glue to the remaining pair of sides (long - side sides) of the battery cell 1 and the upper and lower surfaces of the corresponding side edges.

[0100] The second conveying mechanism 82 includes a base 83, a support member 821 fixed on the base 83, and multiple groups of second conveying components 822 that can move relative to the base 83 and alternately convey the battery cell 1. The second conveying components 822 are used for carrying the battery cell 1 and driving the battery cell 1 to move, and the support member 821 is used for receiving the battery cell 1 conveyed by the second conveying components 822.

[0101] Each second conveying component 822 includes a second support platform 823 and a second conveying driving member for driving the movement of the second support platform 823. When the battery cell 1 is conveyed between the support member 821 and the second support platform 823, at least part of the support member 821 is inserted into the second support platform 823.

[0102] The second conveying driving member includes an X - direction driver 111 for driving the second support platform 823 to move in the first direction and a Z - direction driver 113 for driving the movement in the up - and - down direction. By setting the drivers moving in different directions, it is realized that there is no interference when the second support platform 823 reciprocates. And the size of the second support platform 823 is smaller than the size of the battery cell 1 to facilitate the glue - applying member to apply glue to the edge of the battery cell 1 and avoid interference between the second support platform 823 and the glue - applying member.

[0103] The support member 821 is fixed on the base 83; when the battery cell 1 is conveyed, the second conveying component 822 moves relative to the base 83. Preferably, the X - direction driver 111 is fixed on the base and drives the second support platform 823 to reciprocate relative to the base 83; the Z - direction driver 113 moves synchronously with the second support platform 823.

[0104] In this embodiment, the two groups of second conveying components 822 move interactively and alternately convey the battery cell 1 to the support member 821. The second support platform 823 is located above the base 83 and is arranged corresponding to the support member 821. The X - direction driver 111 and the Z - direction driver 113 corresponding to one of the two groups of second conveying components 822 are installed on one side of the base 83, and the X - direction driver 111 and the Z - direction driver 113 corresponding to the other group of second conveying components 822 are installed on the other side of the base 83 to avoid interference between the drivers when the two groups of second conveying components 822 move.

[0105] When the support member 821 and the second support platform 823 approach each other, at least a part of the support member 821 is inserted into the second support platform 823. Specifically, a groove 824 is formed on the second support platform 823, and the groove 824 is formed along the moving direction of the battery cell 1 (i.e., the first direction). The support member 821 includes a support rod 8211 extending along the moving direction of the battery cell 1 (i.e., the first direction). When the battery cell 1 is conveyed between the support member 821 and the second support platform 823, at least a part of the support rod 8211 is inserted into the groove 824. The height of the support rod 8211 is less than the depth of the groove 824 so that the support rod 8211 can be inserted into the groove 824.

[0106] During the conveyance of the battery cell 1, the support rod 8211 is located between the bottom surface of the groove 824 and the bottom surface of the battery cell 1 so that the support rod 8211 can be inserted into the groove 824. At the same time, after the support rod 8211 receives the battery cell 1, the height of the second support platform 823 decreases so that the battery cell 1 remains on the support rod 8211. At least two grooves 824 are formed on the second support platform 823, and at least two corresponding support rods 8211 are provided on the support member 821 to stably convey and receive the battery cell 1.

[0107] The support member 821 in this embodiment includes a support seat 8213 fixed on the base 83. One end of the support rod 8211 is fixedly connected to the support seat 8213 so that the support rod 8211 forms a cantilever structure. A buffer member 8212 is further provided on the surface of the support rod 8211 in contact with the battery cell 1 to avoid damaging the battery cell 1. The buffer member 8212 is preferably a flexible rubber pad.

[0108] The second conveying mechanism 82 of this embodiment includes a fixedly arranged support member 821 and a second conveying component 822 that moves relative to the support member 821. Among them, the second conveying component 822 only transports the battery cell 1, and the support member 821 receives the battery cell 1 and waits for the second rotating device 72 to adsorb it, so that a plurality of second conveying components 822 cooperate with the support member 821 alternately to convey the battery cell 1, which can effectively improve the conveying efficiency during the preparation process of the battery cell 1, reduce the waiting time, and improve the production rhythm.

[0109] The blanking device 9 includes a base 91, a plurality of blanking platforms arranged on the base 91, a first blanking driving component 931, and a second blanking driving component 932. The plurality of blanking platforms reciprocate along the base 91. The first blanking driving component 931 is used to drive the blanking platform to move in the conveying direction of the battery cell 1, and the second blanking driving component 932 is used to drive at least one blanking platform to be higher or lower than the remaining blanking platforms in the horizontal height to avoid interference between the blanking platforms during movement. The plurality of blanking platforms reciprocate along the base 91 to continuously perform blanking.

[0110] Specifically, the blanking platform in this embodiment includes a first platform 921 and a second platform 922; when the battery cell 1 is conveyed, the first platform 921 and the second platform 922 move relative to each other. The first blanking driving assembly 931 is used to drive the first platform 921 and the second platform 922 to move in the conveying direction of the battery cell 1, and the moving directions of the first platform 921 and the second platform 922 are opposite, so as to realize the simultaneous transmission of the battery cell 1 and avoid interference. The second blanking driving assembly 932 is used to drive one of the first platform 921 or the second platform 922 to rise or fall when the first platform 921 and the second platform 922 approach each other, so as to avoid the other platform. The second blanking driving assembly 932 is fixed below the second platform 922 and moves with the second platform 922.

[0111] The first blanking driving assembly 931 includes a first blanking driver and a synchronous belt fixedly connected to each blanking platform. The first blanking driver is used to drive the synchronous belt to rotate reciprocally, and each blanking platform is fixedly connected to the synchronous belt. In this embodiment, the first platform 921 and the second platform 922 are respectively fixed on both sides of the synchronous belt, so as to realize the driving of the first platform 921 and the second platform 922 to move in opposite directions by one first blanking driver, realize alternating transmission, and the first platform 921 and the second platform 922 form a pair of interlocking mechanisms.

[0112] In this embodiment, the length of the first platform 921 is greater than the length of the second platform 922. The second blanking driving assembly 932 is used to drive the second platform 922 to descend when the first platform 921 and the second platform 922 approach each other, so that the horizontal height of the second platform 922 is lower than that of the first platform 921. When the second platform 922 is lower than the first platform 921, the upper surface of the second platform 922 is at least lower than the lower surface of the first platform 921 by more than the thickness of one battery cell 1 to avoid interference.

[0113] In this embodiment, the second platform 922 includes a fixed plate 941 and a moving plate 942. The moving plate 942 is located above the fixed plate 941. The second blanking driving assembly 932 is used to drive the moving plate 942 to rise or fall relative to the fixed plate 941. The horizontal height of the fixed plate 941 remains unchanged, and it is always lower than the first platform 921 and is fixedly connected to the synchronous belt. The moving plate 942 is used for up and down movement. In order to further ensure the stability of the moving plate 942 during up and down movement, guide rods are provided at the four corners of the moving plate 942, and the guide rods penetrate through the fixed plate 941 and extend downward to guide the moving plate 942 during up and down movement.

[0114] On each blanking platform, there are multiple third support platforms 95 for carrying the battery wafers 1 and a third blanking drive assembly 933 for driving the third support platforms 95 to move relative to the blanking platform. Moreover, the multiple third support platforms 95 on the same blanking platform can also move relative to each other to further improve the transmission efficiency. In this embodiment, the third support platform 95 is a vacuum adsorption platform, which is used to adsorb the battery wafers 1 while transmitting them to prevent the battery wafers 1 from falling.

[0115] Since there are multiple third support platforms 95 for carrying the battery wafers 1 on each blanking platform, multiple battery wafers 1 can be received simultaneously. Or after receiving one battery wafer 1, the third blanking drive assembly 933 drives the third support platform 95 carrying the battery wafer 1 to move, and drives the third support platform 95 without carrying the battery wafer 1 to move below the receiving position to receive the battery wafer 1. After all the third support platforms 95 on this platform have received the battery wafers 1, this blanking platform moves towards the grasping position of the battery wafers 1. The receiving position and the grasping position are respectively located at both ends of the base 91.

[0116] On the base 91, there is a slide rail 961 extending along the transmission direction of the battery wafers 1. At the end of the blanking platform, there is a slider 962 cooperating with the slide rail 961. The slider 962 and the slide rail 961 cooperate to guide the movement of the blanking platform and ensure the stability of the transmission. At the same time, in this embodiment, at the end of the first platform 921, there is a positioning strip 972, and on the base 91, there is a positioner 971. The positioning strip 972 and the positioner 971 cooperate to position the blanking platform, such as positioning the receiving position of the battery wafers 1, the grasping position, and the position when the second platform 922 needs to rise or fall, etc.

[0117] The blanking device 9 of this embodiment, by arranging multiple blanking platforms reciprocatingly moving along the base 91 and enabling at least one blanking platform to be higher or lower than the remaining blanking platforms, avoids interference between the blanking platforms, realizes the reciprocating movement of the blanking platforms, and then transmits the battery wafers 1 simultaneously, making some of the transportation actions run in parallel, leaving sufficient time for the stable production capacity of the equipment and improving the transmission efficiency of the battery wafers 1. There is a height difference between the first platform 921 and the second platform 922. At the same time, the first platform 921 and the second platform 922 are driven by a synchronous belt and a driver to run interlocked, ensuring stability and safety.

[0118] The working process of the glue coating equipment in this embodiment is briefly described as follows:

[0119] The battery wafers 1 are conveyed by the first conveyor belt 21 to the alignment station. The alignment device 3 performs initial alignment on the four sides of the battery wafers 1 to reduce the deviation of the incoming material position. After the initial alignment is completed, the battery wafers 1 are conveyed to the identification station.

[0120] The first vision positioning mechanism 4 corresponding to the identification station acquires the image information of the corresponding cell 1 and transmits it to the loading device 5. The adsorbing member 51 of the loading device 5 adsorbs the cell 1, simultaneously receives the image information, and finely adjusts the position and angle of the cell 1 according to the image information during the loading process, so that the adsorbed cell 1 is finally transmitted to the first support platform 622 of the first conveying mechanism 62 in a posture where the first pair of side edges (short edges) are parallel to the first direction. In this embodiment, the loading device 5 adsorbs two cells 1 at a time.

[0121] After one of the first transfer platforms 621 of the first transfer mechanism 62 receives two cells 1, it is driven by the X-direction driver 111 of the first transfer driving member to move close to the third transfer mechanism 10 after the short edges and chamfers of the cells 1 are coated with glue by the first gluing mechanism 61. And the extension rod 104 and the first conveyor belt 1011 of the third transfer mechanism 10 are inserted into the receiving groove 6221 of the first support platform 622. After being completely inserted into the receiving groove 6221, the Z-direction driver 113 of the first transfer driving member drives the horizontal height of the first transfer platform 621 to decrease, so as to leave the cell 1 on the first conveyor belt 1011. Then, the first transfer platform 621 moves in the reverse direction to continue receiving the cells 1 from the loading device 5 and conveying them. The first support platform 622 is a vacuum adsorption platform to prevent the movement of the cell 1 during the gluing process and the conveying process.

[0122] While the above-mentioned first transfer platform 621 conveys the cell 1 along the first direction after being coated with glue by the first gluing mechanism 61 and transfers it to the third transfer mechanism 10, the other first transfer platform 621 moves in the reverse direction to achieve alternating transfer, reduce the waiting time of the cell 1, and improve the efficiency. And when the two first transfer platforms 621 are transferring, the Z-direction driver 113 of the first transfer driving member drives and controls the horizontal height of the first transfer platform 621 to prevent interference between the two first transfer platforms 621, and to ensure that each loading and unloading is carried out at the same position and height.

[0123] The gluing member driver 612 drives the first gluing member 611 to rotate to apply glue to the first pair of (short edge) sides, chamfers, upper and lower surfaces near the corresponding side edges and chamfer edges of the cell 1 on the moving path of the cell 1. At the same time, it cooperates with the first gluing driving member to drive the gluing position of the gluing member to match different specifications of the cell 1.

[0124] The first conveyor belt 1011 of the first conveying part 101 drives the battery cell 1 to be conveyed onto the second conveyor belt 1021 of the second conveying part 102. Under the blocking action of the stopper 1024, the battery cell 1 is carried by the carrier table 1023. When the adsorption component 712 of the first rotating device 71 moves above the carrier table 1023 or near above the carrier table 1023, the horizontal height of the carrier table 1023 is lifted, lifting the horizontal height of the battery cell 1, and the battery cell 1 is adsorbed by the adsorption component 712 of the first rotating device 71.

[0125] Another identification station is provided on the rotation path corresponding to the first rotating device 71, and a second vision positioning mechanism 13 is correspondingly provided for obtaining the image information of the corresponding battery cell 1. The second rotating device 72 receives this image information and adjusts the position and angle of the battery cell 1 according to this image information during the process of driving the movement of the battery cell 1, so that the adsorbed battery cell 1 is finally placed on the second support table 823 of the second conveying mechanism 82 with the second pair of side edges (long edges) parallel to the first direction.

[0126] One second support table 823 carries the battery cell 1 and moves towards the second rotating device 72. When passing through the second gluing mechanism 81, the gluing part applies glue to the long edge of the battery cell 1. During the gluing process, the second support table 823 carries the battery cell 1 and continues to move forward to complete the gluing.

[0127] When the second support table 823 reaches the position of the support member 821, the support rod 8211 is located between the bottom surface of the groove 824 and the bottom surface of the battery cell 1. Then the second support table 823 carries the battery cell 1 and continues to move forward so that the support rod 8211 is inserted into the groove 824. After the support rod 8211 passes through the groove 824, the Z-direction driver 113 of the second conveying driving part controls the height of the second support table 823 to decrease, so that the battery cell 1 remains on the support rod 8211 and is completely supported by the support rod 8211 and waits to be adsorbed by the second rotating device 72.

[0128] After that, the X-direction driver 111 of the second conveying driving part drives the second support table 823 to move in a direction away from the second rotating device 72, and the above steps are repeated. At the same time, while the X-direction driver 111 of the second conveying driving part drives the second support table 823 to move in a direction away from the second rotating device 72, another second support table 823 also carries another battery cell 1 and moves towards the second rotating device 72, which is the same as the above process.

[0129] After the battery cell 1 is supported on the support rod 8211, it is adsorbed by the adsorption component 712 of the second rotating device 72 and conveyed to the third support table 95 of the blanking device 9.

[0130] The third support platform 95 on the first platform 921 receives the battery cell 1 at one end of the slide rail 961 (receiving position), and then moves towards the other end of the slide rail 961 (grasping position) driven by the first blanking drive assembly 931 and waits for blanking.

[0131] At the same time, since the first platform 921 and the second platform 922 are respectively fixed on both sides of the synchronous belt, while the first platform 921 moves, the second platform 922 moves in the opposite direction. When the first platform 921 and the second platform 922 approach each other, the second blanking drive assembly 932 controls the moving plate 942 of the second platform 922 to move downward, so that the horizontal height of the moving plate 942 is lower than that of the first platform 921.

[0132] When the second platform 922 moves to the receiving position of the battery cell 1, or approaches the receiving position of the battery cell 1, the second blanking drive assembly 932 controls the moving plate 942 of the second platform 922 to move upward to receive the battery cell 1 at the same height.

[0133] After all the third support platforms 95 on the second platform 922 receive the battery cells 1 and the battery cells 1 on the third support platforms 95 of the first platform 921 are removed, driven by the first blanking drive assembly 931, the first platform 921 and the second platform 922 move in the opposite direction to the above direction, that is, the second platform 922 moves towards the grasping position of the battery cell 1, and the first platform 921 moves towards the receiving position of the battery cell 1. When the first platform 921 and the second platform 922 approach each other, the second blanking drive assembly 932 controls the moving plate 942 of the second platform 922 to move downward.

[0134] When the second platform 922 moves to the grasping position of the battery cell 1, or approaches the grasping position of the battery cell 1, the second blanking drive assembly 932 controls the moving plate 942 of the second platform 922 to move upward to wait for the battery cell 1 to be grasped at the same height.

[0135] Continuously repeat the above steps to realize the continuous feeding, loading, gluing, transmission and blanking of the battery cell 1.

[0136] The above-mentioned driver can be adaptively selected as components such as motors, cylinders, and hydraulic cylinders.

[0137] Through the gluing equipment and the above process in this embodiment, during the gluing process of the battery cell, the alternating transmission of the battery cell is realized, the waiting time of the battery cell during transmission is reduced, and the transmission efficiency is improved.
