Description

Technical Field

[0001] The utility model relates to the technical field of battery cell production, and particularly relates to an alternating material pushing and conveying mechanism and a battery cell film wrapping device. Background Art

[0002] Battery cell film wrapping refers to a packaging process for battery cells during the battery manufacturing process. Its main purpose is to protect the battery cells from the external environment, such as preventing moisture from entering and avoiding mechanical damage, and to ensure the stability and safety of the battery. The process of battery cell film wrapping mainly includes: film pulling, positioning, moving, and heat sealing. Among them, the moving process is to control the material pushing mechanism to push the battery cell to move along a predetermined direction at an appropriate speed to ensure that the battery cell is closely attached to the packaging film.

[0003] The inventors of the present application found that in the prior art, a manipulator continuously places unpacked battery cells on a battery cell conveying line, and a material pushing mechanism pushes the battery cells from the placement position to the film wrapping position for film wrapping to obtain wrapped battery cells. When the film wrapping of the battery cells is completed, the material pushing mechanism needs to return to push the next battery cell. During the return journey of the material pushing mechanism, it cannot push the battery cell to move, resulting in the material pushing speed of the material pushing mechanism being lower than the film wrapping speed of the battery cells, and thus reducing the overall speed of the battery cell film wrapping production line. Summary of the Utility Model

[0004] In order to solve the problem of slow film wrapping speed of existing battery cells, the utility model provides an alternating material pushing and conveying mechanism and a battery cell film wrapping device. The specific technical solutions are as follows:

[0005] The utility model includes an alternating material pushing and conveying mechanism body, and the alternating material pushing and conveying mechanism body includes: at least two material pushing mechanisms. The material pushing mechanism includes a material pushing member, and the material pushing member can form a figure-eight moving track. The moving surfaces formed by the figure-eight moving track are all parallel vertical surfaces; a conveying mechanism arranged above the material pushing mechanism, and the conveying mechanism intersects with the top of the figure-eight moving track to form a conveying channel for conveying battery cells.

[0006] Further, the material pushing mechanism further includes: a material pushing moving member, which drives the material pushing member to move along a horizontal plane, and the moving directions of the material pushing moving member and the material pushing member are parallel; and a lifting cylinder arranged on the material pushing moving member, which drives the material pushing member to move along a vertical plane. When the material pushing moving member and the lifting cylinder act together, the material pushing member can form a figure-eight moving track.

[0007] Preferably, the conveying mechanism further includes: conveying brackets symmetrically arranged on both sides of the material pushing moving member; horizontal conveying rollers arranged on the opposite side surfaces of the tops of the conveying brackets, and the opposite surfaces of the horizontal conveying rollers form a conveying channel. The conveying direction of the horizontal conveying rollers is the length direction of the conveying channel, and the length direction of the conveying channel is parallel to the moving direction of the material pushing member.

[0008] Preferably, the vertical planes formed by the figure-eight movement trajectories of the pusher members are all parallel to the opposite sides of the horizontal conveying rollers, and the vertical planes are all arranged within the regions enclosed by the opposite sides.

[0009] Preferably, the conveying mechanism further includes: conveying moving members symmetrically arranged on both sides of the pusher moving member, and the conveying moving member can drive the conveying bracket to move along the moving direction of the pusher member; a horizontal air cylinder arranged at the top of the conveying bracket, the horizontal conveying roller is arranged at the telescopic end of the horizontal air cylinder, and the moving direction of the telescopic end of the horizontal air cylinder is perpendicular to the vertical plane formed by the figure-eight movement trajectory of the pusher member; a vertical conveying roller arranged at the top of the conveying bracket and above the horizontal conveying roller, and the length direction of the vertical conveying roller is perpendicular to the moving direction of the pusher member; and a vertical air cylinder arranged on the conveying bracket, and the vertical air cylinder can drive the vertical conveying roller to approach the horizontal conveying roller.

[0013] In the present utility model, two pusher moving members are provided to push the lifting air cylinder, and the lifting air cylinder pushes the pusher member, so that the pusher member can move left and right and also move up and down simultaneously, enabling it to form a figure-eight movement trajectory. Secondly, by intersecting the top of the figure-eight movement trajectory with the conveying mechanism, both pusher members can push the core along the conveying channel, so that after one pusher member pushes the core to the film wrapping position and returns, the other pusher member can alternately push the next core to continue moving, and further enable the two pusher members to alternately push the core to the film wrapping position, thereby increasing the pusher speed of the present utility model and further increasing its film wrapping speed.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] In the description of the embodiments of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "inside", "outside", "above", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention 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 invention.

[0020] Embodiment 1

[0021] As Figure 1 shown, Embodiment 1 of the present invention includes an alternating material pushing and conveying mechanism body 1. The alternating material pushing and conveying mechanism body 1 includes: at least two material pushing mechanisms 11. The material pushing mechanism 11 includes a material pushing part 114. The material pushing part 114 can form a rectangular moving track, and the moving surfaces formed by the rectangular moving track are all parallel vertical planes; a conveying mechanism 12 arranged above the material pushing mechanism 11. The conveying mechanism 12 intersects with the top of the rectangular moving track at a conveying channel 127 for conveying the battery cell.

[0022] Specifically, in Embodiment 1 of the present invention, the rectangular moving track formed by the material pushing part 114 is the moving track formed by its up and down movement and left and right movement. After the material pushing part 114 moves upward to a point and then moves horizontally, it can intersect with the conveying mechanism 12 at the conveying channel 127, so that the material pushing part 114 can push the battery cell to move along the conveying channel 127 at this time. And after the material pushing part 114 moves downward to a point, even if it moves horizontally, it will not intersect with the conveying mechanism 12, that is, it cannot push the battery cell to move.

[0023] Secondly, the two pusher members 114 can move independently. One pusher member 114 moves along the top of the figure-eight movement track, and the other pusher member 114 can move along the lower part of the figure-eight movement track. When one pusher member 114 pushes the battery cell, the other pusher member 114 does not push the battery cell. Thus, when one pusher member 114 pushes the battery cell to a specified position and is ready to return to the initial position to push the battery cell again, it can move down to a point that does not intersect with the conveying mechanism 12 and then move horizontally to the initial position. At the same time, the other pusher member 114 can move up to a point that intersects with the conveying mechanism 12 and then push the battery cell to move. In this way, the two pusher members 114 alternately push the battery cell in a cyclic manner, which can improve the speed at which the pusher mechanism 11 pushes the battery cell, and further improve the speed at which the battery cell is pushed in the first embodiment.

[0024] Further, the pusher mechanism 11 further includes: a pusher moving member 111 that drives the pusher member 114 to move along a horizontal plane, and the moving directions of the pusher moving member 111 and the pusher member 114 are parallel; and a lifting cylinder 112 disposed on the pusher moving member 111 that drives the pusher member 114 to move along a vertical plane. When the pusher moving member 111 and the lifting cylinder 112 act in cooperation, the pusher member 114 can form a figure-eight movement track.

[0025] Specifically, the pusher moving member 111 can be a servo electric cylinder drive structure or a servo lead screw drive structure, which can control the accuracy of its own horizontal movement through the high-precision rotation of a servo motor. In the first embodiment, the pusher moving member 111 is a servo electric cylinder drive structure.

[0026] Secondly, the pusher member 114 is connected to the lifting cylinder 112 through a pusher force arm 113. The pusher force arm 113 is L-shaped, its short arm is threadedly connected to the telescopic end of the lifting cylinder 112, and its long arm is welded to the pusher member 114, so that when the lifting cylinder 112 drives the pusher force arm 113 to move up and down, it can drive the pusher member 114 to move up and down. The bottom of the lifting cylinder 112 is fixedly connected to the movable plate on the pusher moving member 111 through a threaded connection, so that the pusher moving member 111 can drive the lifting cylinder 112 to move linearly along the horizontal plane, and further enable the pusher member 114 to move both up and down and left and right, thereby forming a figure-eight movement track, and the moving directions of the pusher moving member 111 are parallel, so that the plane formed by the figure-eight movement track is parallel.

[0027] Further, the conveying mechanism 12 further includes: conveying brackets 121 symmetrically disposed on both sides of the pusher moving member 111; horizontal conveying rollers 123 disposed on the opposite side surfaces of the tops of the conveying brackets 121. The opposite surfaces of the horizontal conveying rollers 123 form a conveying channel 127, and the conveying direction of the horizontal conveying rollers 123 is the length direction of the conveying channel 127, and the length direction of the conveying channel 127 is parallel to the moving direction of the pusher member 114.

[0028] Specifically, the middle of the conveying bracket 121 is cylindrical, and its top is a pallet. Along the length direction of the material pushing moving part 111, a horizontal conveying roller 123 is fixedly connected to the top. The horizontal conveying roller 123 has two sets of rollers. The outer surface of one set of rollers is tangent to the lower surface of the battery cell placed thereon, and the outer surface of the other set of rollers is tangent to the side surface of the battery cell. The outer surfaces of the two sets of rollers of the horizontal conveying roller 123 form a conveying channel 127, so that the conveying channel 127 can restrict the up-and-down and front-and-back movement of the battery cell, allow its left-and-right movement, and its movement direction is parallel to the movement direction of the material pushing part 114. Furthermore, the material pushing part 114 can push the battery cell to the film wrapping position to the right under the push of the material pushing moving part 111.

[0029] Furthermore, the vertical planes formed by the figure-eight movement tracks of the material pushing parts 114 are all parallel to the opposite side surfaces of the horizontal conveying roller 123, and the vertical planes are all arranged within the area enclosed by the opposite side surfaces.

[0030] Specifically, the movement tracks of the two material pushing parts 114 are both within the conveying channel 127, so that the two material pushing parts 114 can both pass through the conveying channel 127 to push the battery cell placed thereon. Furthermore, the movement tracks of the two material pushing parts 114 are continuous and will not be blocked by the conveying channel 127. Furthermore, the two material pushing parts 114 can continuously and alternately push the battery cell to its film wrapping position.

[0031] Furthermore, the conveying mechanism 12 further includes: conveying moving parts 122 symmetrically arranged on both sides of the material pushing moving part 111. The conveying moving parts 122 can drive the conveying bracket 121 to move along the movement direction of the material pushing part 114; a horizontal air cylinder 124 arranged on the top of the conveying bracket 121, and the horizontal conveying roller 123 is arranged at the telescopic end of the horizontal air cylinder 124. The movement direction of the telescopic end of the horizontal air cylinder 124 is perpendicular to the vertical plane formed by the figure-eight movement track of the material pushing part 114; a vertical conveying roller 125 arranged on the top of the conveying bracket 121 and above the horizontal conveying roller 123. The length direction of the vertical conveying roller 125 is parallel to the horizontal conveying plane formed by the horizontal conveying roller 123; and a vertical air cylinder 126 arranged on the conveying bracket 121. The vertical air cylinder 126 can drive the vertical conveying roller 125 to approach the horizontal conveying roller 123.

[0032] Specifically, the battery cell is placed in the conveying channel 127, and the horizontal cylinder 124 pushes the horizontal conveying roller 123 so that its outer surface is close to the side of the battery cell and always keeps its relative side parallel to the vertical plane formed by the U-shaped moving trajectory of the pushing piece 114, thereby limiting its movement in the front and rear directions without affecting the movement of the pushing piece 114, and moves to the bottom of the vertical roller under the push of the pushing piece 114, and the vertical cylinder 126 pushes the vertical roller downward so that its outer surface is in close contact with the outer surface of the battery cell and limits its up and down movement. At this time, the conveying moving part 122 can drive the battery cell restricted by the horizontal conveying roller 123 and the vertical roller to move to the right so that it is close to the coating position and is pressed (existing technology), so that the battery cell will not warp up when passing through the vertical roller to enter the coating position, affecting the subsequent process, thereby ensuring the efficiency of pushing the battery cell in Example 1.

[0033] Furthermore, if Figure 2 As shown, a protrusion is formed on the top of each pushing member 114 .

[0034] Specifically, when one pushing piece 114 pushes the battery cell to the right, the other pushing piece 114 can push the battery cell to the left through the protrusion, and then fix the battery cell pushed by the two pushing pieces 114 at a certain position on the conveying channel 127. Therefore, when problems occur in subsequent processes or problems occur in the battery cells on the conveying channel 127, the two pushing pieces 114 can fix the movement of the battery cells, allowing the robotic arm to take them away for easy subsequent operations.

[0035] Example 2

[0036] like Figure 3 As shown, the second embodiment of the present invention includes: the alternating pushing and conveying mechanism body 1 as in the first embodiment; and a coating mechanism 2 arranged at one end of the alternating pushing and conveying mechanism body 1, the coating mechanism 2 is away from the pushing mechanism 11 and close to one end of the horizontal conveying roller 123.

[0037] Specifically, the coating mechanism 2 is arranged at the right end of the horizontal conveying roller 123, so that the battery cells can enter the coating mechanism 2 for coating processing under the alternating push of the two pushing members 114, so that the pushing speed of the pushing mechanism 11 is increased, so that it can match the coating speed, thereby increasing the speed of processing the battery cells in Example 2.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
