Description

Technical Field

[0001] The present application relates to the technical field of lithium battery manufacturing, and in particular to a battery adapter sheet feeding system and a welding device. Background Art

[0002] The adapter sheet is one of the core components of a lithium battery. It mainly has two functions. One is to connect the A and B core packages of the lithium battery together through ultrasonic welding to achieve the parallel connection of the two core packages, increasing the capacity of the battery. The other is to connect the lithium battery top cover to the two core packages to play a role in transmitting current.

[0003] In the current adapter sheet welding equipment, the adapter sheet feeding device mostly uses feeding above the material bin: the adapter sheet is placed in a specific material bin, and there is a lifting rod at the bottom of the material bin to lift the adapter sheet to the upper outlet to complete the feeding of the adapter sheet, and then the transfer of the adapter sheet is completed through the cooperation of the servo module and the cylinder. The current adapter sheet feeding method usually has the following problems during operation: Generally, there are multiple material bins on the feeding device. When the feeding of a certain material bin is completed, the lifting rod is at the uppermost end. When changing the material bin, the lifting rod needs to be moved to the lowermost end first, and then the material bin is replaced. This up-and-down process will lose a certain amount of manufacturing time and reduce production efficiency. Moreover, multiple sensors need to be installed on the equipment so that the computer system can identify and control the operation of the lifting rod. If the sensor is accidentally blocked, an alarm will be generated, causing the equipment to stop, which will further affect the production efficiency of the equipment. Finally, in the feeding stage, the adapter sheet is divided into copper sheets and aluminum sheets. Sometimes, if it is not found in time that the two connecting sheets are bonded and then transported to the electrode tab of the battery cell for welding, it will cause major quality problems.

[0028] 1.

[0046] For better understanding and implementation, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0047] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs. The terms used in the specification of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0049] Refer to Figure 1 , the present application discloses a battery adapter sheet feeding system, whose main function is to transport or convey the adapter sheet to be welded to a welding device or other process equipment, realizing automatic blanking and feeding of the adapter sheet. At the same time, it can also be combined with an adapter sheet loading device to realize automatic loading of the adapter sheet, improving the processing efficiency of this process or related processes. The adapter sheet here can be a copper adapter sheet or an aluminum adapter sheet. Of course, through the design of the feeding device and the blanking device structure, it is also possible to realize simultaneous feeding of copper adapter sheets and aluminum adapter sheets. The structure, working process, etc. of the battery adapter sheet feeding system of this solution will be described in detail below.

[0050] Refer to Figure 1 , the present application discloses a battery adapter sheet feeding system, which is characterized in that it includes a blanking device 4, a feeding device 1, and a material bin 2 with a blanking port 34 at the bottom.

[0051] The feeding device 1 moves to the position of the blanking device 4 and obtains the adapter sheet from the material bin through the blanking device 4, and then transports the adapter sheet to the target position.

[0052] The blanking device 4 includes a feeding tray 42, a blanking port 43 is provided on the feeding tray 42, the material bin 2 is installed on the feeding tray 42, and the blanking port 34 is located above the blanking port 43 and aligned with the blanking port 43.

[0053] A blanking baffle 441 is also provided on the feeding tray 42, as Figure 4As shown in the figure. When the feeding device 1 does not move to the position of the blanking device 4, the blanking baffle 441 is placed between the blanking opening 34 and the blanking port 43 to block the blanking opening 34. During blanking, the feeding device 1 moves to the position of the blanking device 4 and enters the blanking port 43. The blanking baffle 441 is synchronously withdrawn from between the blanking opening 34 and the blanking port 43. The transfer piece in the material bin 2 falls and passes through the blanking opening 34 and lands on the feeding device 1.

[0054] Based on the above solution, by using a material bin 2 with a blanking opening 34 at the bottom, and the material bin 2 is installed on the feeding tray 42, and the blanking opening 34 is kept above and aligned with the blanking port 43 on the feeding tray 42. In this way, during blanking, when the feeding device 1 moves to the position of the blanking device 4 and enters the blanking port 43, the blanking baffle 441 is synchronously withdrawn from between the blanking opening 34 and the blanking port 43. On the one hand, the blanking port 43 is vacated to provide space for the feeding device to enter the blanking port. On the other hand, the blanking opening is released, and the transfer piece in the material bin 2 automatically falls under its own gravity and passes through the blanking opening 34 and lands on the feeding device 1 located at the position of the blanking port 43. The feeding device 1 obtains or receives the transfer piece and then transports the transfer piece to the target position or the designated position or the welding station or the next process position.

[0055] In the above solution, by setting a blanking opening at the bottom of the material bin and aligning the blanking opening with the blanking port on the feeding tray, when the feeding device moves to the position of the blanking port, the blanking baffle is synchronously withdrawn from the position below the blanking opening. The transfer piece in the material bin automatically falls onto the feeding device under its own gravity, and then the transfer piece is transported to the target position by the feeding device, realizing fully automatic blanking and improving the blanking efficiency.

[0056] In the above solution, the transfer piece can be a copper transfer piece or an aluminum transfer piece, and the copper transfer piece or the aluminum transfer piece can be placed in the material bin 2. Of course, in some production systems, it can be arranged according to the type of transfer piece required at the target position. If the target position requires the copper transfer piece and the aluminum transfer piece to be received alternately, the copper transfer piece and the aluminum transfer piece can also be placed alternately in the material bin 2. Here, the type of transfer piece placed in the material bin and the placement method of the transfer piece are not limited, as long as when the blanking baffle 441 is withdrawn from between the blanking opening 34 and the blanking port 43, the transfer piece will fall under its own gravity and enter the feeding device at the position of the blanking port.

[0057] In the above solution, a blanking port 34 is provided at the bottom of the bin 2, and the transfer piece is blanked through the blanking port and the feeding port. During the entire blanking process, there is no need to use a top push rod, avoiding the problem of low feeding efficiency caused by the reciprocating push of the top push rod in the prior art. In addition, during the blanking and feeding processes of this application, there is no need for many sensors for detection and positioning, reducing the failure rate and saving the system manufacturing, use, and maintenance costs.

[0058] In the above solution, during blanking, the feeding device moves to the position of the blanking device and enters the feeding port. The blanking baffle synchronously withdraws between the blanking port and the feeding port. The feeding device and the blanking baffle move synchronously to realize the receiving of the transfer piece, reducing the turnover of the transfer piece receiving, and reducing the failure rate during the blanking and feeding processes of the transfer piece.

[0059] In this technical solution, as Figure 4 shown, a telescopic reset mechanism is connected to the side of the blanking baffle 441 away from the feeding device 1. During blanking, the feeding device 1 moves to the position of the blanking device 4 and enters the feeding port 43, synchronously pushing the blanking baffle 441. The blanking baffle 441 moves and compresses the telescopic reset mechanism, withdrawing from the feeding port 43. When the feeding device 1 withdraws from the feeding port 43, the telescopic reset mechanism pushes the blanking baffle 441 to reset synchronously, blocking the blanking port 34.

[0060] In the above solution, by the feeding device 1 pushing the blanking baffle 441, during blanking, the feeding device 1 moves to the position of the blanking device 4, and the blanking baffle 441 synchronously withdraws between the blanking port 34 and the feeding port 43. At this time, the blanking port is exposed, and the feeding device replaces the original blanking baffle. The transfer piece in the bin 2 falls, and the transfer piece enters the feeding device 1 at the position of the feeding port through the blanking port, and the feeding device obtains the transfer piece.

[0061] In the above solution, a telescopic reset mechanism is connected to the side of the blanking baffle 441 away from the feeding device 1, so that when the feeding device receives the transfer piece and withdraws from the feeding port, the blanking baffle 441 can move synchronously in the same direction as the feeding device under the potential energy of the telescopic reset mechanism, and the blanking baffle resets into the feeding port. At this time, the blanking baffle again plays a role in blocking the falling of the transfer piece in the bin 2, avoiding the continuous falling of the transfer piece in the bin.

[0062] In this technical solution, as Figure 4As shown, the telescopic reset mechanism includes an elastic member 443 that deforms along the moving direction of the blanking baffle 441. One end of the elastic member 443 is connected to the blanking baffle 441, and the other end is connected to the feeding tray 42. The elastic member 443 has potential energy. When the blanking baffle is pushed by the feeding device, the elastic member is compressed. When the feeding device withdraws from the blanking port, the thrust of the feeding device on the blanking baffle gradually decreases. Under the action of the potential energy of the elastic member 443, the blanking baffle synchronously resets along with the movement of the feeding device.

[0063] Of course, in some embodiments, the elastic member 443 can also be installed on the side close to the feeding device 1. In this way, when the feeding device pushes the blanking baffle, the elastic member will be stretched by the blanking baffle. When the feeding device withdraws from the blanking port, the potential energy of the elastic member resets and pulls the blanking baffle to reset.

[0064] As Figure 4 shown, the elastic member is a spring. To ensure the deformation direction of the spring, a spring connecting rod 442 is sleeved inside the spring. The spring connecting rod 442 is parallel to the moving direction of the blanking baffle. The deformation direction of the spring is restricted by the spring connecting rod 442. The connection between the spring connecting rod 442 and the spring and the blanking baffle 441 and the feeding tray 42 is realized. A blanking baffle connecting plate 45 is fixedly installed on the feeding tray 42. The blanking baffle connecting plate 45 is fixedly connected to the spring connecting rod 442. The spring is sleeved on the spring connecting rod 442.

[0065] Of course, in some embodiments, the elastic member can also be elastic rubber.

[0066] In the technical solution, when the blanking baffle does not withdraw or does not completely withdraw from directly below the blanking port, the upper surface of the blanking baffle remains in contact with the lower surface of the blanking port. It is ensured that when blanking is not carried out, the transfer sheets in the bin cannot cross the blanking port, ensuring that only one transfer sheet enters the feeding device at a time, avoiding the adhesion problem of two or more transfer sheets, and ensuring the safety performance of the battery after welding.

[0067] In the technical solution, at least two blanking ports 43 are provided on the feeding tray 42. The blanking ports 43 are symmetrically arranged on the feeding tray 42. A bin is fixedly installed above each blanking port 43. A rotation driving device is connected to the feeding tray 42. The rotation driving device drives the feeding tray 42 to rotate, and transports each bin on the feeding tray 42 to the docking position with the feeding device 1.

[0068] In the above scheme, the feed tray 42 is driven to rotate by the rotary drive device, so that the multiple feed ports arranged in an axisymmetric shape and the silos installed on each feed port can be connected with the feeding device alternately in sequence. In this way, when one silo is carrying out or waiting for feeding, another or several silos are carrying out feeding and replenishing operations, avoiding the process of waiting for replenishment after the adapter piece in the silo is used up, thereby improving the feeding efficiency.

[0069] like Figure 4 As shown, in this solution, the number of upper and lower material ports of the feed tray 42 is preferably four. The four material ports are arranged on the feed tray in an axisymmetric shape.

[0070] In the technical solution, the rotary drive device includes a material unloading rotating shaft 52 and a groove wheel mechanism driven to rotate by the material unloading rotating shaft 52. The groove wheel mechanism includes a dial 432 fixedly connected to the material unloading rotating shaft 52 and a groove plate 434 driven to rotate by the dial 432, and the groove plate 434 is fixedly connected to the material supply plate 42.

[0071] The slotted plate 434 is provided with a plurality of radially-arranged slots, the number of which matches the number of the unloading ports 43 on the feeding plate 42. The dial 432 is provided with a lever, which cooperates with the slot and moves in and out of the slot to drive the dial 432 to rotate.

[0072] In the above scheme, the grooved wheel mechanism is provided to realize the intermittent rotational motion of the driving grooved disc 434, and at the same time, the intermittent rotation of the feed disc 42 fixed with the grooved disc 434 is also realized. When the feed disc is unloading, the dial 432 cannot drive the grooved disc 434 to rotate. When the feeding device is transporting the adapter sheet, or when the feeding device is preparing to enter the unloading port, the dial 432 drives the grooved disc 434 to rotate, so that the unloading port on the feed disc rotates to a position suitable for the feeding device.

[0073] like Figure 5 As shown, the rotary drive device also includes a base 41 for mounting a dial 432 and a slotted plate 434. By mounting on the base, the rotary drive device is easy to install and operate.

[0074] Here, a Geneva mechanism is adopted, which can also ensure that the feeding device and the blanking device can be driven by a driving device 5 at the same time. That is, the driving device 5 drives the blanking device and the feeding device at the same time, and drives them through a Geneva structure and a crank assembly respectively, so that the blanking device and the feeding device can meet the motion adaptation relationship, so that the feeding device and the blanking port on the feeding tray driven by the Geneva mechanism can cooperate, so that the feeding device can smoothly obtain the transfer pieces in the bin 2 from the position of the blanking port. The specific structure and driving method for the feeding device and the blanking device to be driven by a driving device 5 at the same time will be introduced in detail later when the feeding device is introduced.

[0075] In this technical solution, as Figure 2 shown, the feeding device 1 includes a feeding cavity 151 for holding transfer pieces and a conveying mechanism for conveying the feeding cavity 151. The feeding cavity 151 includes a cavity body adapted to the blanking port 43 and a transfer bin placed on the cavity body, and the depth of the transfer bin is consistent with the thickness of the transfer piece. During blanking, the cavity body enters the blanking port 43, and the upper surface of the transfer bin contacts the lower surface of the material dropping port 34, and the transfer pieces enter the transfer bin through the material dropping port 34.

[0076] In the above solution, the depth of the transfer bin is consistent with the thickness of the transfer piece, so that the transfer pieces enter the transfer bin, and only one transfer piece enters the transfer bin of the feeding cavity 151, avoiding two or more transfer pieces being transported to the target position at the same time, and avoiding multiple transfer pieces being welded at the same position during welding, thus avoiding battery safety accidents.

[0077] In the above solution, during blanking, the upper surface of the transfer bin contacts the lower surface of the material dropping port 34, so that the transfer pieces just fall into the transfer bin. At the same time, it also enables the transfer bin to provide good protection for the transfer pieces during the process of receiving and transporting the transfer pieces, avoiding problems such as deformation of the transfer pieces. In the above technical solution, it can be simply deduced that the upper surface of the transfer bin is flush with the upper surface of the blanking baffle. When the feeding device 1 moves to push the blanking baffle, that is, when the feeding cavity 151 pushes the blanking baffle, the upper surface of the transfer bin is flush with the upper surface of the blanking baffle, which can lift the transfer pieces in the bin during the process of the feeding cavity 151 pushing the blanking baffle, avoiding the problem of tilting of the transfer pieces, and ensuring that the transfer pieces in the bin 2 will fall into the transfer bin only after the transfer bin completely enters directly below the material dropping port, so as to protect the transfer pieces during the blanking process of the transfer pieces and ensure the quality of the transfer pieces.

[0078] In this technical solution, as Figure 2As shown in the figure, the conveying mechanism includes a slide rail 156, a slider 155 slidably connected to the slide rail 156, and a sliding drive mechanism for driving the slider 155 to slide along the slide rail 156. The slide rail 156 is parallel to the moving direction of the feeding device 1. The slider 155 is fixedly connected to the cavity body and drives the cavity body to move between the target position and the blanking port 43 under the drive of the sliding drive mechanism.

[0079] In the above solution, the sliding drive mechanism, the slide rail 156 and the slider 155 realize the movement of the feeding cavity 151, with a simple structure and reliable and stable movement of the feeding cavity 151.

[0080] In the above solution, in order to install the feeding cavity 151 on the slider 155, while ensuring the quality and precision of the feeding cavity 151, or the feeding cavity 151 can be replaced according to the model of the adapter plate, a cavity tray 152 is also provided between the feeding cavity 151 and the slider 155. The feeding cavity 151 is installed on the cavity tray 152, and the cavity tray is installed on the slider 155.

[0081] In this technical solution, as Figure 2 shown, the sliding drive mechanism includes a power push rod 132 fixedly connected to the slider 155 and parallel to the slide rail. One end of the power push rod 132 away from the slider 155 is connected with a crank assembly. The crank assembly includes a first connecting rod 135 and a second connecting rod 136. Two ends of the first connecting rod 135 are respectively rotatably connected to one end of the power push rod 132 and one end of the second connecting rod 136. One end of the second connecting rod 136 away from the first connecting rod 135 is fixedly connected with a rotating shaft, and a drive mechanism for driving the rotating shaft to rotate is connected to the rotating shaft.

[0082] As Figure 2 shown, the power push rod 132 is indirectly fixedly connected to the slider 155. The drive mechanism drives the rotating shaft to rotate.

[0085] As Figure 6 shown, the driving device further includes a motor 56 for driving the feeding rotating shaft 54, a first gear 51 fixedly connected to the feeding rotating shaft 54, a second gear 53 meshing with the first gear 51, and the second gear 53 is fixedly connected to the blanking rotating shaft 52. The blanking rotating shaft 52 is fixedly connected to the dial 432, driving the rotation of the dial 432 and the object associated with the dial 432, thereby driving the feeding tray to rotate.

[0086] As Figure 6 shown, the motor 56 is installed on the mounting base plate 11 through a motor mounting plate 55, and both the motor 56 and the motor mounting plate 55 are provided at the bottom of the mounting base plate 11, while the feeding device and the blanking device are both placed above the mounting base plate 11, facilitating the layout and installation of equipment components.

[0087] In this technical solution, as Figure 3As shown, the silo 2 includes a silo body 31, an adapter plate groove 33 disposed in the silo body 31, and the drop opening 34. Before the silo is installed on the feed tray 42, the drop opening 34 is detachably installed with a sealing plate 32. When the silo 2 is not installed with the feed tray, the sealing plate 32 is used to block the drop opening on the silo to prevent the adapter plate in the silo from falling from the drop opening, ensuring that the adapter plate remains in the silo. When the silo is installed on the feed tray, the sealing plate 32 is pulled out or removed, so that the drop opening on the silo will be docked with the drop opening below it, which is convenient for subsequent material unloading.

Figure 4 To realize the feeding of two feeding trays, the groove wheel mechanism includes two groove trays 434, as shown in FIG. Figure 5 As shown, the slotted disks include a copper slotted disk 431 and an aluminum slotted disk 433 , and the two slotted disks are simultaneously moved by a dial 432 and rotate synchronously.

[0089] The feeding device 1 has two feeding cavities 151, such as Figure 2 As shown, the two feeding cavities 151 are respectively docked with the two supply trays 42, and a power connecting rod 12 is connected between the two feeding cavities 151. The power driving 132 is fixedly connected to the power connecting rod 12, pushing the two feeding cavities 151 to move synchronously, and respectively obtain the copper adapter plate and the aluminum adapter plate from the discharge port 43 position on the two supply trays 42, and transport them to the target position synchronously.

[0090] In the above scheme, two feeding trays are provided, which are used to install the copper sheet bin 21 and the aluminum sheet bin 22 respectively, so that the copper adapter sheet and the aluminum adapter sheet can be unloaded and fed at the same time, which is simple to operate and has high unloading and feeding efficiency, and meets the welding requirements of the welding equipment.

[0091] The present application also discloses a welding device, including the aforementioned battery adapter feeding system, which can realize automatic unloading and feeding, and can realize simultaneous unloading and feeding of copper adapters and aluminum adapters, thereby improving the efficiency of unloading and feeding, and improving the efficiency of the welding process. It can also ensure that in one feeding, whether it is a copper adapter or an aluminum adapter, only one piece is transported, avoiding the problem of multiple adapters sticking together, improving welding efficiency and welding quality, and ensuring the safety performance of the battery after welding.

[0092] The technical means disclosed in the solution of this application are not limited to the technical means disclosed in the above embodiments, but also include technical solutions formed by any combination of the above technical features.
