Abstract
Description
Technical Field

[0002] During the production process of lithium batteries, it is necessary to attach insulating sheets to the positive and negative end faces of the battery cells. Currently, in most lithium battery production processes, the battery cells generally enter the insulating sheet attachment station in a horizontal position, with the positive and negative end faces of the battery cells facing forward. After the insulating sheets are adsorbed by the adsorption mechanism, they are attached to the battery cells. Since the battery cells are in a horizontal position, a relatively large equipment space is required, and during the attachment process, usually two power mechanisms are needed, one for material taking and one for material pushing, resulting in complex equipment and high costs.
[0003] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0036] Embodiment
[0037] Please refer to Figure 1 and Figure 2 , which schematically shows a cell insulation sheet attaching device 10, including a feeding mechanism 100, a picking mechanism 200, a carrying platform 300, and a film tearing mechanism 400. Along the vertical direction (z-axis), the feeding mechanism 100, the picking mechanism 200, and the carrying platform 300 are arranged in sequence. The feeding mechanism 100 is used to provide insulation sheets. The cell 12 to which the insulation sheet is to be attached is placed on the carrying platform 300, and the electrode end of the cell 12 faces upward, that is, the surface of the cell 12 to which the insulation sheet is to be attached faces upward. The picking mechanism 200 moves back and forth between the feeding mechanism 100 and the carrying platform 300 and performs a 180° flip to attach the insulation sheet on the feeding mechanism 100 to the cell 12.
[0038] Specifically, in this embodiment, the feeding mechanism 100 has a feeding chamber 111 for accommodating the insulation sheets 11. The feeding chamber 111 is vertically arranged, and a feeding outlet is opened at the bottom. A plurality of insulation sheets 11 are stacked in the feeding chamber 111 and are taken out from the feeding outlet at the bottom. The feeding mechanism 11 can replenish the insulation sheets from above the feeding chamber without stopping the machine.
[0039] Further, the feeding cavity 111 is formed by enclosing a plurality of vertical rods 112. For example, in one embodiment, the cross-section of the vertical rod 112 is L-shaped, and the four vertical rods 112 are arranged corresponding to the four corners of the insulating sheet 11 to enclose the feeding cavity 111 for good positioning of the insulating sheet 11.
[0040] Specifically, in this embodiment, the carrying platform 300 is arranged directly below the feeding mechanism 100. The battery cell 12 reaches the carrying platform 300 through equipment such as a conveying mechanism or a jaw, and the end face of the battery cell 12 to be attached is facing the feeding outlet. For example, a positioning block or a positioning groove can be arranged on the carrying platform 300 to align the placement position of the battery cell 12 with the position of the feeding outlet.
[0041] Please refer to Figures 3 to 7 , specifically, in this embodiment, the picking mechanism 200 is arranged between the feeding mechanism 100 and the carrying platform 300, and includes a sliding track 210, a connecting rod assembly 220, a picking member 230, and a pushing member 240. When the pushing member 240 moves downward, it drives the connecting rod assembly 220 to slide along the sliding track 210, realizing a 180° rotation of the connecting rod assembly 220, so that the picking member 230 is horizontally flipped to the discharging state with the picking surface facing downward; when the pushing member 240 moves upward, it drives the connecting rod assembly 220 to move in the reverse direction, so that the picking member 230 is horizontally flipped to the picking state.
[0042] Specifically, the sliding track 210 is opened on the mounting plate 250. The mounting plate 250 is vertically arranged and simultaneously provides a mounting position for the pushing member 240. The picking member 230 can grasp and release the insulating sheet. The picking member 230 is slidably connected to the sliding track through the connecting rod assembly 220. The pushing member 240 pushes the connecting rod assembly 220 to move along the sliding track 210, thereby driving the picking member 230 to reciprocate between the picking position and the discharging position. At the discharging position, the picking member 230 is located at a position close to the feeding outlet, and the picking surface of the picking member 230 is arranged upward. At the discharging position, the picking member 230 is located at a position close to the battery cell, and the picking surface of the picking member 230 is arranged downward. Among them, the picking surface of the picking member 230 is the end face used for contacting and grasping the insulating sheet.
[0043] Specifically, in this embodiment, the sliding track 210 includes a first moving track 211, a second moving track 212, and a flipping track 213. The first moving track 211 and the second moving track 212 are arranged in the vertical direction, and the flipping track 213 is arranged in the horizontal direction. The flipping track 213 is respectively communicated with the first moving track 211 and the second moving track 212. Specifically, the flipping track 213 is communicated with one side of the first moving track 211 and the second moving track 212, and the entire sliding track 210 is generally in a T-shaped structure.
[0044] In this embodiment, one end of the connecting rod assembly 220 is pivotally connected to the pushing member 240 and fixedly connected to the material taking member 230, and the other end is slidably connected to the sliding track 210. Specifically, the connecting rod assembly 220 includes a connecting rod 221, a rotating shaft 222, and a cam follower 223. The connecting rod 221 has a first end 22a and a second end 22b. The first end 22a is fixedly connected to the rotating shaft 222, and the second end 22b is fixedly connected to the cam follower 223. The cam follower 223 is slidably connected to the sliding track 210.
[0045] Further, connection holes are provided at both the first end 22a and the second end 22b of the connecting rod 221. The cam follower 223 includes a shaft rod, a bearing portion, and a fixing portion. The bearing portion is slidably connected in the sliding track 210. One end of the shaft rod is rotatably connected to the bearing portion, and the other end passes through the connection hole at the second end 22b of the connecting rod and is fixed to the fixing portion. The fixing portion can be, for example, a bolt, and the shaft rod is locked and fixed to the connecting rod 221 by the bolt.
[0046] One end of the rotating shaft 222 is fixedly connected to the first end 22a of the connecting rod 221, the other end passes through the pushing member 240, and is fixedly connected to the material taking member 230, and the rotating shaft 222 is pivotally connected to the pushing member 240. Specifically, the pushing member 240 includes a driving member 241, a guiding rail 242, and a pushing plate 243. The guiding rail 242 is provided on the mounting plate 250 and is vertically arranged on one side of the first moving track 211 and the second moving track 212 away from the flipping track 213. The pushing plate 243 is slidably connected to the guiding rail 211 through a slider. The driving member 241 is used to push the pushing plate 243 to move along the guiding rail 242 to drive the connecting rod 221 to move along the sliding track 210. Specifically, the driving member 241 can be, for example, a power mechanism such as a motor or a cylinder. In this embodiment, the driving member 241 is preferably a rodless cylinder. The sliding block of the rodless cylinder is fixed to the pushing plate 243 to push the pushing plate 243 to move. More preferably, the rodless cylinder is arranged on one side of the guiding rail 242 away from the sliding track 210.
[0047] Further, a connection through hole 201 is provided on the pushing plate 243. The rotating shaft 222 is rotatably inserted through the connection through hole 201. A bearing member 247 is provided between the rotating shaft 222 and the connection through hole 201 to pivotally connect the rotating shaft 222 to the pushing plate 243. Specifically, the bearing member 247 is a pedestal bearing. The pedestal bearing is fixed to the pushing plate 243, and the rotating shaft is rotatably arranged in the shaft hole of the pedestal bearing.
[0048] Further, an upwardly protruding extension portion 248 is provided on one side of the pushing plate 243 close to the sliding track 210. The connection through hole 201 is provided in the extension portion 248, so that the connection point between the pushing plate 243 and the connecting rod 221 is higher than the connection point between the pushing plate 243 and the guiding rail 242. This setting makes it easier for the connecting rod 221 to flip when the pushing plate reciprocates.
[0049] Further, the pushing member 240 further includes an elastic stretching member 244. The two ends of the elastic stretching member 244 are respectively connected to the pushing plate 243 and the end 22b of the connecting rod 221, and are used to apply a force to the end 22b of the connecting rod 221 to move towards the flipping track 213.
[0050] Specifically, the elastic stretching member 244 includes a tension spring 245 and a connecting piece 246. One end of the tension spring 245 is connected to the end 22b of the connecting rod 221, and the other end is connected to the pushing plate 243 through the connecting piece 246. The connection point of the tension spring 245 and the connecting piece 246 is located on the side of the flipping track 213 away from the first moving track 211 / second moving track 212. As Figure 6 shown, the first moving track 211 is arranged on the right side of the flipping track 213, and the connection point of the tension spring 245 and the connecting piece 246 is located on the left side of the flipping track 213. The connecting piece 246 can be, for example, a sheet metal part and is fixed to the side wall of the pushing plate 243 by means of screw locking. By arranging the connecting piece 246 and shifting the connection point of the tension spring 245 to the left, the connecting rod 221 can more easily enter the flipping track 213, thereby completing the flipping.
[0051] Further, a first arc transition portion 214 is provided at the connection of the first moving track 211 and the flipping track 213, and a second arc transition portion 215 is provided at the connection of the second moving track 212 and the flipping track 213. The first arc transition portion 214 and the second arc transition portion 215 are mirror-symmetrical and bend in opposite directions. By providing the two arc transition portions, the cam follower 223 can enter and exit the flipping track 213 more smoothly.
[0052] Further, the material taking member 230 can be a mechanical claw material taking mechanism, a suction cup type material taking mechanism, a magnetic adsorption type material taking mechanism, etc. Preferably, in one embodiment, the material taking member 230 includes a housing 231, a vacuum generator (not shown in the figure) disposed in the housing 231, and a suction cup 232 disposed on one side surface of the housing 231. The vacuum generator is connected to the suction cup 232 and is used to make the suction cup 232 generate an adsorption force. The number of the suction cups 232 can be one or more to better adsorb the insulating sheet. At the material taking position, the suction cup 232 sucks the insulating sheet 11 from the feeding outlet, and then moves to the material placing position, and the suction cup 232 releases the insulating sheet 11 to make the insulating sheet adhere to the electrode end of the battery cell.
[0053] Specifically, the front surface of the insulating sheet is the adsorption surface in contact with the suction cup 232, and an adhesive for adhering to the battery cell is provided on the back surface of the insulating sheet, and a release paper is attached to the surface of the adhesive. When the material taking member 230 sucks the insulating sheet, the suction cup 232 adsorbs to the front surface of the insulating sheet. After the material taking member 230 is flipped by 180°, the release paper is torn off, so that the surface of the insulating sheet with the adhesive adheres to the battery cell, completing the attachment of the insulating sheet.
[0054] See also Figure 8 The film-tearing mechanism 400 includes a film-tearing moving rail 410, a moving member 420 slidably connected to the film-tearing moving rail 410, and a pneumatic clamp 430 fixed to the moving member 420. The film-tearing moving rail 410 is arranged on one side of the loading platform 300 and arranged along the horizontal direction (x axis). The moving member 420 moves along the film-tearing moving rail 410 to the film-tearing position, and the pneumatic clamp 430 clamps the release paper on the insulating sheet 11. The moving member 420 continues to move to drive the pneumatic clamp 430 to move, so that the release paper is separated from the insulating sheet. Specifically, the moving member 420 can be driven by a corresponding driving mechanism, such as a cylinder, a motor or a magnetic suspension drive, to move along the film-tearing moving rail 410.
[0055] Further, in one embodiment, the pneumatic clamp 430 includes a clamp 431 and a clamp driver 432, and the clamp driver 432 is used to drive the clamp 431 to move along the y-axis so that the clamp 431 extends or retracts, thereby adjusting the clamping position of the clamp 431. It is understandable that in other embodiments, the clamp driver may not be provided.
[0056] Furthermore, the cell insulation sheet attaching device 10 further includes a waste bin 500, which is arranged on the side of the cell away from the film tearing mechanism 400 along the y-axis direction to save space. The waste bin 500 is provided with an opening 510 for the pneumatic clamping jaws 430 to enter and exit. After the pneumatic clamping jaws 430 enter the opening 510, the release paper is released. The release paper is collected in the waste bin 500.
[0057] The working principle of the battery cell insulation sheet attaching device 10 of this embodiment is as follows:
[0058] The external device places the battery cell on the loading platform 300 with the electrode end facing upward. In the initial state, the material taking mechanism 200 is located at the material taking position, such as Figure 5 As shown, the connecting rod 221 is in a posture with the head end 22a facing upward and the tail end 22b facing downward, and the material picking surface of the material picking member 230 faces upward and directly faces the material feeding outlet. After the material picking member 230 sucks the insulating sheet from the material feeding outlet, the push plate 243 moves downward, driving the connecting rod 221 to move downward, and the tension spring 245 pulls the connecting rod 221 to move to the left, and the cam follower 223 enters the flipping track 213 from the first moving track 211, and the tail end 22b of the connecting rod 221 moves to the left and enters the flipping track 213. The push plate 243 continues to move downward, and at this time, the head end 22a of the connecting rod 221 flips downward under the push of the push plate 243, as shown in FIG. Figure 6As shown, the push plate 243 continues to move downward, driving the end 22b of the connecting rod 221 to move rightward into the second moving track 212. At this time, the connecting rod 221 completes a 180° flip and assumes a posture with the end 22b facing upward and the head end 22a facing upward, and the picking surface of the picking member 230 faces downward. The push plate 243 continues to drive the connecting rod 221 to move downward to the discharging position, as Figure 7 shown.
[0059] The film tearing mechanism 400 is activated. The moving member 420 moves along the film tearing moving track 410 to the film tearing position. The pneumatic gripper 430 grips the release paper on the insulating sheet 11. The moving member 420 continues to move, driving the pneumatic gripper 430 to move so that the release paper is separated from the insulating sheet. The moving member 420 drives the pneumatic gripper 430 to move to the opening 510 of the waste bin 500, and the pneumatic gripper 430 releases the release paper, completing the film tearing process.
[0060] After the film tearing is completed, the picking member 230 continues to move downward to release the insulating sheet, so that the insulating sheet adheres to the battery cell. After the insulating sheet is adhered, the push plate 243 moves upward, driving the connecting rod 221 to move upward. When the end 22b of the connecting rod 221 enters the flipping track 213, the push plate 243 continues to move upward, causing the head end 22a of the connecting rod 221 to flip upward, driving the picking member 230 to flip to a state where the picking surface faces upward.
