Technical Field

[0001] This utility model relates to the field of battery patching, specifically to an insulating sheet application device. Background Technology

[0002] With the explosive growth of the new energy vehicle market, the demand for lithium-ion batteries is increasing daily. As one of the mainstream forms, the protection technology of the individual cell casings of prismatic lithium-ion batteries directly affects the reliability and lifespan of the battery system. Applying a blue film coating to the outer surface of the cell is one method of protecting it. In actual production, due to battery structure limitations, a film coating alone cannot completely cover the battery surface; therefore, insulating sheets need to be attached to the battery terminals to ensure the integrity of the battery coating.

Therefore, there is a need to provide a high-precision and high-efficiency battery insulating sheet attaching device.

[0004] In summary, existing insulating sheet application devices have low application accuracy and efficiency, making them unsuitable for the current application requirements of insulating sheets on the terminal side of lithium batteries. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 As shown in the figure, this utility model embodiment discloses an insulating sheet application device, including a feeding mechanism 1, a feeding and application mechanism 2, a film peeling mechanism 3, a battery cell fixing mechanism 4, a release paper collection mechanism 5, and a support platform 6.

[0026] Specifically, according to Figure 2 As shown, the feeding mechanism 1 includes a magazine feeding mechanism 11, a frame 12, a magazine feeding mechanism switching cylinder 13, and an insulating sheet lifting servo module 14. The magazine feeding mechanism 11 includes two sets, one for preparing materials and the other for feeding materials.

[0027] according to Figure 3As shown, the magazine loading mechanism 11 includes a hopper 111, an insulating sheet lifting block 112, a pole post hole positioning post 113, an insulating sheet 114, a base 115, a first sensor 116, and a second sensor 117. The hopper 111 is a frame structure composed of four limiting plates of the same length, and the space inside the frame matches the size of the insulating sheet lifting block 112. The insulating sheet lifting block 112 is a rectangular block component with a hollow center, which can fit into the space formed by the hopper 111, and the hollow center can fit precisely into the pole post hole positioning post; the upper surface of the insulating sheet lifting block 112 matches the size of the insulating sheet 114, and the lower surface is connected to the insulating sheet lifting servo module 14. The pole post hole positioning post 113 passes through the insulating sheet lifting block 112 and is fixed to the base 115, and the size of the positioning post matches the pole post hole of the insulating sheet 114. The insulating sheet 114 is a rectangular insulating sheet with a pole hole in the middle. When the insulating sheet 114 is fixed to the insulating sheet lifting block 112 through the pole hole positioning post 113, the insulating sheet 114 exactly matches the upper plane of the insulating sheet lifting block 112. The base 115 is a rectangular block component with a hollow center, located at the bottom of the hopper 111. The hopper 111 can be fixed to the base 115 with bolts. The first sensor 116 is located at the frame of the hopper 111. The sensor contains a position sensing device that can sense the lifting position of the insulating sheet lifting block 112, thereby limiting the lifting position of the insulating sheet each time. The second sensor 117 is located at the base 115. It contains a weight sensing device or a quantity sensing device that can sense whether there are still insulating sheets 114 on the platform of the insulating sheet lifting block 112.

[0028] See Figure 2 The frame 12 is a large rectangular plate-shaped component used to fix the feeding mechanism 1, the film-tearing mechanism 3, and the release paper collecting mechanism 5. The feeding mechanism 1 is located at one end of the frame 12, and the film-tearing mechanism 3 and the release paper collecting mechanism 5 are located at the other end of the frame 12. The parts of the frame 12 corresponding to the feeding mechanism 1 and the release paper collecting mechanism 5 are designed to be hollow.

[0029] See Figure 2 The magazine loading mechanism switching cylinder 13 includes a cylinder and a switching platform. The switching platform is located on the upper wall of the frame 12 through a pre-reserved opening in the frame 12, while the cylinder is located on the lower wall of the frame 12 and connected to the lower wall of the switching platform through the opening in the frame 12. The switching platform is a rectangular plate-shaped component, and its upper wall is fixedly connected to the base supports 115 of the two magazine loading mechanisms 11. The two magazine loading mechanisms 11 are located at opposite ends of the switching platform, and the portion connecting the switching platform to the base supports 115 is also openwork. The cylinder can indirectly control the position switching of the magazine loading mechanisms 11 by controlling the rotation of the switching platform.

[0030] See Figure 2The insulating sheet lifting servo module 14 is located on the lower wall of the frame 12. The insulating sheet lifting servo module 14 is connected to the insulating sheet lifting block 112 through the pre-reserved cutouts in the frame 12, the pre-reserved cutouts in the switching platform, and the pre-reserved cutouts in the base 115, thereby controlling the lifting and lowering of the insulating sheet lifting block 112. During use, the insulating sheet lifting servo module 14 lifts the insulating sheet support block 112. After the first sensor 116 senses that the insulating sheet 114 has been lifted to the corresponding position, the insulating sheet lifting servo module 14 stops lifting, and the material picking and applying mechanism 2 picks up the insulating sheet 114. After each picking up of the insulating sheet 114, the first sensor 116 senses the position change of the insulating sheet 114, thereby controlling the insulating sheet lifting servo module 14 to raise the position. When the insulating sheet 114 is used up, the second sensor 117 senses that there is no insulating sheet 114 on the insulating sheet support block 112. The magazine feeding mechanism switching cylinder 13 rotates the switching platform, thereby realizing the position switch between the feeding group and the preparation group of the magazine feeding mechanism 11. At this time, the empty insulating sheet support block 112 is replenished, and the next cycle begins.

[0031] See Figure 4 The material feeding and application mechanism 2 includes a support 21, a horizontal moving module 22, a vertical lifting module 23, a rotary cylinder 24, and an insulating sheet suction plate 25. The support 21 includes a column and a fixed plate. The column is fixed to the upper wall of the support platform 6, located between the feeding mechanism 1 and the film-tearing mechanism 3. The fixed plate is located at the other end of the column and has multiple bolt holes. The horizontal moving module 22 is bolted to the outer surface of the fixed plate and can move horizontally. The vertical lifting module 23 is fixed to the outer surface of the horizontal moving module 22 and can move vertically. One end of the rotary cylinder 24 is rotatably connected to the outer surface of the vertical lifting module 23. The rotary cylinder 24 can move flexibly within a certain range via the horizontal moving module 22 and the vertical lifting module 23; the other end of the rotary cylinder 24 is connected to the insulating sheet suction plate 25. The insulating sheet suction plate 25 is a rectangular plate-shaped component with a size smaller than the insulating sheet 114. One end is fixed to the rotary cylinder 24 to achieve adsorption of the insulating sheet 114.

[0032] See Figure 5The film-tearing mechanism 3 includes a film-tearing bracket 31, a gripper cylinder 32, a film-tearing gripper 33, and a translation cylinder 34. The film-tearing bracket 31 is a rectangular plate component of a certain length, one end of which is fixed to the gripper cylinder 32, and the other end is slidably connected to the translation cylinder 34 via a slider. The gripper cylinder 32 is fixed to the upper end of the film-tearing bracket 31, providing power to the film-tearing gripper 33 for operation. The film-tearing gripper 33 consists of a rectangular plate and a rectangular block. The rectangular plate is fixed, and the rectangular block swings under the power provided by the gripper cylinder 32, thus opening and closing to tear the film from the insulating sheet 114. The translation cylinder 34 is located at the bottom end of the film-tearing bracket 31 and is slidably connected to the film-tearing bracket 31 via a slider. The translation cylinder 34 indirectly controls the horizontal movement of the film-tearing gripper 33 through the film-tearing bracket 31, realizing the film-tearing step of the insulating sheet 114.

[0033] See Figure 6 The battery cell fixing mechanism 4 includes a fixing base 41, an upgrading cylinder 42, a centering cylinder 43, a battery cell gripper 44, and a battery cell 45. The fixing base 41 is located at the right end of the release paper collecting mechanism 5 and is fixed to the upper wall of the support platform 6 by bolts. Two sets of upgrading cylinders 42 are included, with their lower ends located at opposite ends of the fixing base 41. The lower wall of the centering cylinder 43 is fixedly connected to the upper wall of the upgrading cylinder 42. The centering cylinder 43 enables precise centering, ensuring a fixed position. The battery cell gripper 44 is fixed to the upper wall of the centering cylinder 43 and is used to fix the battery cell 45.

[0034] See Figure 1 The release paper collection mechanism 5 includes a collection channel 51 and a collection box 52; the collection channel 51 is a funnel-shaped channel, wider at the top and narrower at the bottom. Its upper end is secured to the upper wall of the frame 12 through a pre-reserved opening, located next to the film-tearing mechanism 3, and is used to receive the release paper torn off by the film-tearing mechanism 3. The collection box 52 is located at the end of the channel 51 and is used to collect the release paper.

[0035] See Figure 1 The support platform 6 is a rectangular plate-shaped component. The feeding mechanism 1, the material picking and applying mechanism 2, the film tearing mechanism 3, the battery cell fixing mechanism 4, and the release paper collecting mechanism 5 are all fixed to the support platform 6.

[0036] See Figure 1 The working process of the device in this embodiment of the utility model is as follows: During the application of insulating sheets, the two sets of magazine feeding mechanisms 11 first feed the insulating sheets 114. After feeding is completed, the insulating sheet lifting servo module 14 lifts the insulating sheet support block 112 of the feeding group. When the first sensor 116 detects that the insulating sheet support block 112 has been lifted to the corresponding position, it controls the insulating sheet lifting servo module 14 to stop lifting. At this time, the material picking and applying mechanism 2 controls the vertical lifting module 23, the horizontal moving module 22, and the rotary cylinder 24 to apply the insulating sheet. The suction plate 25 moves to the top of the insulating sheet 114 to pick up the insulating sheet 114. After being picked up, the insulating sheet 114 moves to the position of the film-tearing mechanism 3. The film-tearing claw 33 clamps the release paper, and the translation cylinder 34 moves horizontally, thereby tearing the release paper off the insulating sheet 114. The release paper slides into the release paper collection mechanism 5. The centering cylinder 42 completes the fixing and positioning of the battery cell 45. At this time, the insulating sheet 114 after the film has been torn off is applied by the material-picking and applying mechanism 2. When the second sensor 117 senses that the insulating sheet of the feeding group of the magazine feeding mechanism 11 has been used up, it controls the magazine feeding mechanism switching cylinder 13 to rotate and switch. The original material preparation group becomes the new material feeding group, and the operator places the new insulating sheet 114 on the insulating sheet lifting block 112 through the pole hole positioning post 113.

[0037] This utility model application achieves precise positioning of the insulating sheet 114 by setting a positioning post 113 with a pole hole on the insulating sheet support block 112. The design of two sets of spring clip feeding mechanisms 11 enables simultaneous feeding and preparation of materials, further accelerating the application efficiency. The cooperation of the film peeling mechanism 3, the material picking and applying mechanism 2, and the cell fixing mechanism 4 enables unmanned operation of the entire application process. This utility model achieves precise application of the insulating sheet without visual guidance.
