Description

Technical Field

[0001] The present invention relates to the technical field of soft-pack lithium battery production equipment, and in particular to an automatic secondary edge sealing feeding device for square soft-pack lithium batteries. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive electrode material and the negative electrode material, and uses a non-aqueous electrolyte solution. Among them, lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally batteries that use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and use a non-aqueous electrolyte solution, while lithium ion batteries are generally batteries that use lithium alloy metal oxides as the positive electrode material, graphite as the negative electrode material, and use a non-aqueous electrolyte. Lithium ion batteries do not contain metallic lithium and are rechargeable. Soft-pack lithium batteries are a type of lithium-ion battery. Soft-pack lithium batteries are liquid lithium-ion batteries covered with a layer of polymer shell. Soft-pack lithium batteries have the characteristics of light weight and high safety. Because the polymer shell mostly uses aluminum-plastic film as the packaging material, the overall weight is lighter. In the event of a safety hazard, the soft-pack lithium battery will only bulge and crack, and will not explode, thus having higher safety.

[0003] In order to reduce the thickness, the existing soft-pack lithium batteries mostly adopt a square cell structure. In the production process of square soft-pack lithium batteries, an aluminum-plastic composite film is wrapped on the outside of the square cell, and electrolyte is injected into the membrane cavity before packaging. In order to further improve the sealing during the packaging process, the battery film edge needs to be subjected to secondary edge sealing processing. The secondary edge sealing processing is to perform a secondary folding action on the opening position of the aluminum-plastic composite film. Most of the existing square soft-pack lithium batteries are placed in batches using battery trays. There are multiple placement grooves distributed inside the battery tray for the batteries to be placed and fixed. However, most of the existing square soft-pack lithium batteries are placed on the edge sealing station by manual placement, that is, the batteries are taken out one by one from the battery tray manually, resulting in low efficiency. In addition, the battery placement position cannot be guaranteed to be accurate during manual handling and placement, which affects the subsequent edge sealing processing.

[0004] In addition, the battery tray will produce a large shake during transportation, which will cause the multiple square soft-pack lithium batteries inside the battery tray to collide with each other, resulting in the bending and deformation of the square soft-pack lithium battery cells. If the square battery cells are deformed, the two sides of the square battery will be uneven, which will cause wrinkles in the aluminum-plastic film outside the square battery cells, and then cause the opening of the aluminum-plastic film to be uneven, thereby affecting the subsequent edge sealing of the aluminum-plastic film opening. Therefore, the straightness of the square battery cells must be ensured before the secondary edge sealing of the square soft-pack lithium battery.

[0005] Reference patent publication number is "CN105633478B", and the patent name is "An automatic double-sealing molding production line". The technical solution discloses "An automatic double-sealing molding production line, including a feeding unit, a packaging unit, a molding unit and a feeding unit, the feeding unit includes a feeding pull belt, the packaging unit includes a primary sealing station and a primary cutting station, the primary sealing station is arranged next to the primary sealing correction station, the primary sealing station is provided with an upper packaging cavity, a lower packaging cavity and an active cavity, the primary cutting station is provided with a primary cutting mechanism for cutting the edge of the battery cell, the molding unit includes a battery cell transfer machine The present invention integrates the loading unit, packaging unit, molding unit and unloading unit into one device, thereby realizing the fully automatic production of soft-pack lithium batteries from loading to unloading. Although this technical solution can effectively realize the automation of loading and unloading of soft-pack lithium batteries, it cannot ensure that the square battery cells remain straight during the loading and sealing of square soft-pack lithium batteries, thus affecting the quality of subsequent battery sealing.

[0061] Embodiment 2, in order to realize the automatic clamping and straightening action of the battery after being taken out, ensure the straightness of the battery cell, and prevent the deformation of the battery cell from affecting the subsequent edge sealing processing, in this embodiment: by providing a pallet conveying plane 1; a material taking device 4 and a flipping and clamping device 5, a fully loaded battery pallet is conveyed through the pallet conveying plane 1, the material taking device 4 is arranged near the end of the pallet conveying plane 1, and the flipping and clamping device 5 is also arranged near the material taking device 4, and the flipping and clamping device 5 includes a sliding plate 51 and a supporting plate 52, one end of the supporting plate 52 is close to the bottom of the material taking device 4, so that one side of the sliding plate 51 is slidably arranged above the supporting plate 52 By respectively providing a fixed vertical plate 53 and a movable slide plate 54 on the other side of the sliding plate 51, the movable slide plate 54 is slidably provided on the other side of the sliding plate 51, so that one side of the fixed vertical plate 53 faces the outside of the movable slide plate 54, and by providing a plurality of correction vertical plates 55 on the movable slide plate 54, and by providing a plurality of rotating mechanisms 56 on one side of the fixed vertical plate 53, and by providing a rotating suction plate 57 on the power output end of the plurality of rotating mechanisms 56, the rotation direction of the plurality of rotating suction plates 57 can be controlled one by one by the plurality of rotating mechanisms 56, so that one side of the plurality of rotating suction plates 57 and the plurality of correction vertical plates 55 are aligned. One side corresponds to another side; a pushing mechanism 58 is provided on the outside of the supporting plate 52, so that the power output end of the pushing mechanism 58 is connected to the outside of the sliding plate 51, so that the pushing mechanism 58 can be used to control the sliding distance of the sliding plate 51. When the pushing mechanism 58 drives the sliding plate 51 to move toward the material taking device 4, a plurality of rotating suction plates 57 can be aligned with a plurality of pneumatic clamps 42 one by one, so that one side of the rotating suction plate 57 can adsorb the battery side on the pneumatic clamp 42. At this time, the pneumatic clamp 42 is released, and a pulling mechanism 59 is also provided on the sliding plate 51, so that the power output end of the pulling mechanism 59 is aligned with another side of the pneumatic clamp 42. The outside of the moving slide 54 is connected so that the pulling mechanism 59 is used to control the moving distance of the moving slide 54, and then the moving slide 54 drives a plurality of correction vertical plates 55 to move toward a plurality of rotating suction plates 57. In the process of the correction vertical plates 55 moving toward the rotating suction plates 57, one side of the correction vertical plates 55 performs a correction action on the square soft-pack lithium battery cells on the rotating suction plates 57. When the plurality of correction vertical plates 55 are aligned one by one with the plurality of rotating suction plates 57, the correction action is completed, which effectively ensures that the two side surfaces of the square soft-pack lithium battery cells remain straight, and reduces the situation where the secondary edge sealing is affected by wrinkles in the aluminum-plastic film on the outside of the cells.

[0062] It is particularly noted that after the correction of the cells of the square soft-pack lithium battery is completed, the moving slide plate 54 is reset by the pulling mechanism 59, so that the several correction vertical plates 55 are away from the several rotating suction plates 57, and the several correction vertical plates 55 are prevented from blocking the several rotating suction plates 57 from rotating. The several rotating mechanisms 56 drive the several rotating suction plates 57 to rotate, so that the side of the rotating suction plate 57 that adsorbs the battery faces upward, so that the square soft-pack lithium battery is in a flat state, which is convenient for loading.

[0063] It should be noted that in order to perform correction actions for square soft-pack lithium battery cells of different thicknesses, it is necessary to adjust the spacing between the correction vertical plate 55 and the rotating suction plate 57. In this embodiment, by further providing an adjusting cylinder 541 on the moving slide plate 54, and further providing a connecting horizontal plate 542 on the power output end of the adjusting cylinder 541, a plurality of correction vertical plates 55 are evenly arranged on one side of the connecting horizontal plate 542. Therefore, the adjusting cylinder 541 can be used to control the moving distance of the connecting horizontal plate 542. When the power output end of the adjusting cylinder 541 is pushed out, the connecting horizontal plate 5 One side of the plurality of correction vertical plates 55 on 42 is close to one side of the plurality of rotating suction plates 57, that is, the distance between one side of the correction vertical plate 55 and one side of the rotating suction plate 57 is reduced. When the power output end of the adjusting cylinder 541 retracts, the one side of the plurality of correction vertical plates 55 connected to the horizontal plate 542 is driven to move away from one side of the plurality of rotating suction plates 57, that is, the distance between one side of the correction vertical plate 55 and one side of the rotating suction plate 57 is increased. The distance between the correction vertical plate 55 and the rotating suction plate 57 can be effectively adjusted to be suitable for square soft-pack power battery cells with different thicknesses.

[0064] It should also be noted that in order to ensure that when the pneumatic clamp 42 of the material picking device 4 is close to the rotating suction plate 57, the battery clamped by the pneumatic clamp 42 can be stably adsorbed by the rotating suction plate 57, at least two adsorption through holes 571 can be provided on the side of the rotating suction plate 57 facing the correction vertical plate 55, and the two adsorption through holes 571 are positioned symmetrically. Therefore, the square soft-pack lithium battery in a vertical state can be adsorbed on the side close to the rotating suction plate 57. Since the two adsorption through holes 571 are symmetrically positioned, the force is ensured to be stable.

[0065] Embodiment 3, in order to realize the action of automatically placing the square soft-pack lithium battery after flipping and flattening on the edge sealing station, the square soft-pack lithium battery on one side of the rotating suction plate 57 is taken out and the automatic placement action is realized.

Therefore, the linear drive module 61 can drive the material taking suction plate 62 to be directly above the rotating suction plate 57. At this time, the pressing mechanism 64 can be used to drive the material taking suction plate 62 to move downward, so that the material taking suction plate 62 moves toward the rotating suction plate 57. The plate 57 is moved directly above the plate 57 until it approaches the surface of the square soft-pack lithium battery above the rotating suction plate 57. After completing the battery material picking action on the rotating suction plate 57, the power output end of the pressing mechanism 64 is reset. At this time, the material picking suction plate 62 with the battery rises, and the linear drive module 61 drives the material picking suction plate 62 with the battery to move close to the battery conveying plane 7 again. By arranging a plurality of battery clamps directly above the battery conveying plane 7, the battery conveying plane 7 can be used to convey a plurality of battery clamps to the edge sealing station, and a plurality of battery clamps can also be used to place the battery to be edge sealed. The linear drive module 61 drives the material taking suction plate 62 with the battery to align with the battery fixture. At this time, the pressing mechanism 64 drives the material taking suction plate 62 to approach the battery fixture until the square soft-pack lithium battery is completely placed inside the battery fixture, completing the action of placing the square soft-pack lithium battery in the battery fixture, and driving the battery fixture into the edge sealing station through the battery conveying plane 7, effectively realizing the automated placement action of the square soft-pack lithium battery, ensuring that the straight square soft-pack lithium battery is placed flatly in the battery fixture to feed the secondary edge sealing process.

[0066] It should be noted that, in this embodiment, in order to clamp the square soft-pack lithium batteries on the several rotating suction plates 57 one by one, a plurality of groups of adsorption hole groups 621 can be provided on the side of the material taking suction plate 62 facing the sliding plate 51, and the plurality of groups of adsorption hole groups 621 correspond one by one to the plurality of rotating suction plates 57. Therefore, when the material taking suction plate 62 is close to the top of the plurality of rotating suction plates 57, the square soft-pack lithium batteries on each rotating suction plate 57 can be adsorbed through the plurality of groups of adsorption hole groups 621. In this process, it is necessary to further describe that in order to improve the surface adsorption stability of the square soft-pack lithium batteries by the adsorption hole groups 621, each group of adsorption hole groups 621 can include two adsorption circular holes, and the two adsorption circular holes can be adjacent to each other, thereby ensuring stable adsorption.

[0067] Embodiment 4, in order to realize automatic movement of the empty battery tray at the end of the pallet conveying plane 1 to the beginning of the pallet output plane 2, so as to transport the empty battery tray through the pallet output plane 2, since a plurality of square soft-pack lithium batteries are placed in the battery tray, after the plurality of pneumatic clamps 42 of the material picking device 4 have completely clamped and taken out the plurality of square soft-pack lithium batteries in the battery tray, the empty battery tray needs to be moved, so as to facilitate the subsequent full battery tray to be aligned with the material picking device 4 again. In this embodiment: by providing a pallet conveying plane 1 and a pallet output plane 2, the end of the pallet conveying plane 1 is adjacent to the beginning of the pallet output plane 2, so that the pallet conveying plane 1 can be used to transport the full battery tray, and the pallet output plane 2 can also be used to transport the empty battery tray, the moving device 3 is located between the end of the pallet conveying plane 1 and the beginning of the pallet output plane 2, and then the moving device 3 can be used to move the empty battery tray to the pallet output plane 2;

Therefore, when the empty battery tray at the end of the tray conveying plane 1 needs to be moved, the lifting cylinder 32 can be driven by the linear moving module 31 to be located just above the end of the tray conveying plane 1, so that the lifting cylinder 32 drives the installation cross plate 34 to move toward the empty battery tray until the installation cross plate 34 The tightening cylinders 35 at both ends are aligned with the outer sides of the empty battery tray respectively. At this time, the tightening cylinders 35 drive the right-angle bent plate 36 to approach the side of the battery tray until the right-angle bent plate 36 cooperates with the side groove of the battery tray, that is, the clamping action of the empty battery tray is completed. At this time, the power output end of the lifting cylinder 32 retracts, driving the empty battery tray to rise, so that the empty battery tray is separated from the end of the tray conveying plane 1, and the linear moving module 31 drives the lifting cylinder 32 to move to the top of the starting end of the tray output plane 2 again. At this time, the power output end of the lifting cylinder 32 drives the empty battery tray to approach the starting end of the tray output plane 2, and places the empty battery tray on the starting end of the tray output plane 2. After alignment and placement, the power output ends of the two tightening cylinders 35 retract, so that the right-angle bent plate 36 is separated from the side groove of the battery tray, thereby releasing the empty battery tray, so as to automatically place the empty battery tray on the tray output plane 2 and convey the empty battery tray through the tray output plane 2.

[0069] With respect to this embodiment, it is necessary to further describe that, in order to ensure the accurate position of the battery tray during the process of moving the empty battery tray, so that the right-angle bent plate 36 can accurately cooperate with the side groove of the battery tray to realize the clamping action of the battery tray, and the empty battery tray can be accurately placed on the starting end of the tray output plane 2, a pushing cylinder 311 is also provided at the bottom of the linear moving module 31, and two pushing cylinders 311 are provided.
