Description

Technical Field

[0001] The utility model relates to the technical field of base film tearing, in particular to a base film tearing device. Background Art

[0002] With the rapid development of new energy vehicles, technologies related to power batteries have also developed rapidly. Power soft-pack cells are an important part of power batteries. During the production and processing of soft-pack cells, double-sided tape needs to be pasted on the soft-pack cells. Double-sided tape is generally pasted on the surface of soft-pack cells to facilitate the subsequent assembly of electronic devices, to adhere the soft-pack cells to the housing or frame of the electronic device, or to facilitate the fixing of multiple soft-pack cells together to assemble into a battery pack.

[0003] Double-sided adhesive tape usually consists of a base film, an adhesive tape body and a cover paper. When applying adhesive tape, the base film needs to be torn off, and the adhesive tape body needs to be exposed before the adhesive tape is applied to the battery cell. In the prior art, an automatic adhesive tape machine is usually used for adhesive tape application. However, the automatic adhesive tape machine in the prior art has limitations in the base film tearing device, and cannot accurately and stably position the base film, resulting in the inability of the automatic adhesive tape machine to accurately and quickly peel off the base film, which affects the film tearing quality and efficiency. Utility Model Content

[0004] The utility model aims to provide a bottom film tearing device, which realizes accurate positioning of the bottom film and improves the film tearing quality and film tearing efficiency.

[0005] A bottom film tearing device comprises a film tearing positioning platform, a bottom film clamping assembly, a film tearing horizontal moving assembly and a film tearing driving assembly. The film tearing horizontal moving assembly drives the film tearing positioning platform to move horizontally so that the film tearing positioning platform approaches or moves away from the film tearing driving assembly. The bottom film clamping assembly is arranged on a side of the film tearing positioning platform close to the film tearing driving assembly and is used to clamp the bottom film of the adhesive tape. The film tearing driving assembly cooperates with the bottom film clamping assembly to tear off the bottom film of the adhesive tape.

[0006] In the above technical solution, the film-tearing positioning platform is used to place the adhesive tape to be torn off, which ensures the stability of the adhesive tape during the film-tearing process, prevents displacement or offset during the film-tearing process, ensures the quality of the film-tearing, and provides a reference point for the bottom film clamping assembly and the film-tearing driving assembly to accurately cooperate. The bottom film clamping assembly is used to position and clamp the bottom film of the adhesive tape, and the film-tearing driving assembly cooperates with the bottom film clamping assembly to tear off the bottom film. When in use, the adhesive tape to be torn off is placed on the film-tearing positioning platform, the bottom film clamping assembly clamps the bottom film of the adhesive tape, and then the film-tearing horizontal moving assembly drives the film-tearing positioning platform to move horizontally so that the film-tearing positioning platform is close to the film-tearing driving assembly. When the film-tearing positioning platform is close to the film-tearing driving assembly, the film-tearing driving assembly grabs the adhesive tape, and then the film-tearing horizontal moving assembly drives the film-tearing positioning platform to move horizontally so that the film-tearing positioning platform is away from the film-tearing driving assembly. At this time, the bottom film is separated from the adhesive tape under the action of the bottom film clamping assembly. The utility model realizes rapid and stable positioning of the bottom film and ensures the quality and efficiency of film tearing through the cooperation of the bottom film clamping component, the horizontal film tearing moving component and the film tearing driving component.

[0007] Furthermore, the bottom film clamping assembly includes a rotating drive, a clamping drive and a clamping unit. The rotating drive is arranged on the film tearing positioning platform, and the output end of the rotating drive is connected to the clamping drive. The rotating drive and the clamping drive respectively drive the clamping unit to rotate and clamp.

[0008] In the above technical solution, during the film tearing process, the clamping unit is the component that actually contacts the bottom film and applies the clamping force, and can stably and reliably clamp the bottom film. The rotary drive can drive the clamping unit to rotate, so that the clamping unit can adjust the direction or angle of the bottom film while clamping the bottom film, thereby improving the film tearing efficiency. The clamping drive is responsible for driving the clamping unit to perform the clamping action to ensure that the bottom film is firmly clamped during the tearing process.

[0009] Furthermore, the clamping unit includes a first positioning rod, a second positioning rod and at least two clamping blocks, the first positioning rod and the second positioning rod are arranged in parallel, and the two clamping blocks are arranged opposite to the first positioning rod and the second positioning rod.

[0010] In the above technical solution, after the adhesive tape to be torn off is placed on the film-tearing positioning platform, the clamping drive member drives the first positioning rod and the second positioning rod to approach each other, so that the two clamping blocks can be precisely aligned to clamp the bottom film of the adhesive tape. Then the film-tearing horizontal moving assembly drives the film-tearing positioning platform to approach the film-tearing driving assembly. After the film-tearing driving assembly grabs the adhesive tape, the rotating driving member drives the clamping driving member to rotate, so that the first positioning rod and the second positioning rod rotate. Then the film-tearing horizontal moving assembly drives the film-tearing positioning platform away from the film-tearing driving assembly. The bottom film of the adhesive tape is separated from the adhesive tape under the action of the two clamping blocks and the film-tearing driving assembly. Finally, the clamping drive member drives the first positioning rod and the second positioning rod to separate, so that the two clamping blocks are separated, and the bottom film loses its restriction and separates from the film-tearing positioning platform.

[0011] Furthermore, the film tearing drive assembly includes a grabbing robot, a horizontal moving assembly and a vertical moving assembly. The horizontal moving assembly drives the vertical moving assembly to drive the grabbing robot to move horizontally, and the vertical moving assembly drives the grabbing robot to move vertically so that the grabbing robot moves close to or away from the film tearing positioning platform.

[0012] In the above technical solution, the grabbing manipulator is the core component of the film tearing drive assembly, which is responsible for directly grabbing and tearing off the bottom film of the adhesive tape. By accurately controlling the movement of the grabbing manipulator, efficient and accurate grabbing of the bottom film can be achieved. The horizontal moving assembly is responsible for driving the vertical moving assembly to move in the horizontal direction, so that the grabbing manipulator is close to the film tearing positioning platform in the horizontal direction. The vertical moving assembly is responsible for driving the grabbing manipulator to move in the vertical direction to achieve the grabbing manipulator's accurate grabbing and tearing of the bottom film. By accurately controlling the movement of the vertical moving assembly, it can be ensured that the grabbing manipulator operates at the correct position and height.

[0013] Furthermore, a plurality of suction nozzles arranged in a matrix are provided on one side of the grabbing robot close to the film tearing positioning platform.

[0014] In the above technical solution, the suction nozzle grabs and fixes the non-base film part of the adhesive tape through suction to facilitate the removal of the base film. The matrix arrangement of the suction nozzles means that the gripping manipulator can apply suction to multiple points of the adhesive tape at the same time, thereby achieving a more stable and efficient grip, effectively preventing the adhesive tape from sliding or falling off during the removal of the base film.

[0015] Furthermore, the film tearing horizontal movement assembly includes a driving member, a slider and a guide rod, the slider is connected to the film tearing positioning platform, and the driving member drives the slider to drive the film tearing positioning platform to move horizontally along the guide rod.

[0016] In the above technical solution, the driving member serves as a power source and can efficiently drive the slider to move along the guide rod, thereby reducing energy loss and improving movement efficiency, so that the film tearing positioning platform can respond quickly and complete the required horizontal movement.

[0017] Furthermore, it also includes a material frame, which is arranged on the moving path of the film tearing positioning platform.

[0018] In the above technical solution, the material frame can conveniently collect the torn bottom film, avoid the bottom film from being scattered, and keep the working environment clean and hygienic. Specifically, the material frame is arranged on the moving path of the film tearing positioning platform, and when the bottom film is separated from the film tearing positioning platform, it falls into the material frame.

[0019] Furthermore, it also includes an air supply component, which is arranged adjacent to the material frame, and the air supply component includes a hose and an air nozzle connected to the hose.

[0020] In the above technical solution, the hose has the characteristic of being able to be bent in various directions. During the film tearing process, the hose is bent along the direction of the film tearing so that the air nozzle on the hose faces the bottom film. The air nozzle blows air toward the bottom film, so that the bottom film can smoothly detach from the film tearing positioning platform and fall into the material frame.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. Set up a film-tearing horizontal moving component. During the film-tearing process, the film-tearing horizontal moving component first drives the film-tearing positioning platform close to the film-tearing driving component. After the film-tearing driving component grabs the adhesive tape, the film-tearing horizontal moving component drives the film-tearing positioning platform away from the film-tearing driving component, so that the base film is separated from the adhesive tape, thereby improving the film-tearing efficiency.

[0023] 2. Set up a bottom film clamping assembly. When the adhesive tape to be torn off is placed on the film tearing positioning platform, the bottom film clamping assembly positions and clamps the bottom film of the adhesive tape. When the film tearing horizontal moving assembly drives the film tearing positioning platform away from the film tearing driving assembly, the bottom film is separated from the adhesive tape under the action of the bottom film clamping assembly, thereby realizing the peeling of the bottom film and the adhesive tape and improving the film tearing quality.

[0024] 3. Set up a film tearing drive assembly. When the film tearing horizontal moving assembly drives the film tearing positioning platform to approach the film tearing drive assembly, the film tearing drive assembly grabs the adhesive tape and cooperates with the film tearing horizontal moving assembly and the bottom film clamping assembly to tear off the bottom film, thereby further improving the film tearing efficiency and quality.

[0036] The bottom film tearing device of the utility model will be further described in detail below in conjunction with specific embodiments and drawings. The drawings provide preferred embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0037] Please refer to Figure 1 In a preferred embodiment, the bottom film tearing device of the utility model includes a film tearing positioning platform 1, a bottom film clamping component 2, a film tearing horizontal moving component 3 and a film tearing driving component 4. The film tearing horizontal moving component 3 drives the film tearing positioning platform 1 to move horizontally so that the film tearing positioning platform 1 is close to or away from the film tearing driving component 4. The bottom film clamping component 2 is arranged on the side of the film tearing positioning platform 1 close to the film tearing driving component 4, and is used to clamp the bottom film of the adhesive tape. The film tearing driving component 4 cooperates with the bottom film clamping component 2 to tear off the bottom film of the adhesive tape.

[0038] In the actual application of the above structure, the film-tearing positioning platform 1 is used to place the adhesive tape to be torn off, ensuring the stability of the adhesive tape during the film-tearing process, preventing displacement or offset during the film-tearing process, ensuring the quality of the film-tearing, and providing a reference point for the bottom film clamping component 2 and the film-tearing driving component 4 to accurately cooperate. The bottom film clamping component 2 is used to position and clamp the bottom film of the adhesive tape, and the film-tearing driving component 4 cooperates with the bottom film clamping component 2 to tear the bottom film. When in use, the adhesive tape to be torn off is placed on the film-tearing positioning platform 1, the bottom film clamping component 2 clamps the bottom film of the adhesive tape, and then the film-tearing horizontal moving component 3 drives the film-tearing positioning platform 1 to move horizontally so that the film-tearing positioning platform 1 is close to the film-tearing driving component 4. When the film-tearing positioning platform 1 is close to the film-tearing driving component 4, the film-tearing driving component 4 grabs the adhesive tape, and then the film-tearing horizontal moving component 3 drives the film-tearing positioning platform 1 to move horizontally so that the film-tearing positioning platform 1 is away from the film-tearing driving component 4. At this time, the bottom film is separated from the adhesive tape under the action of the bottom film clamping component 2. The utility model realizes fast and stable positioning of the bottom film and ensures the quality and efficiency of film tearing through the cooperation of the bottom film clamping component 2, the horizontal film tearing moving component 3 and the film tearing driving component 4.

[0039] For details, please refer to Figure 2 , the bottom film clamping assembly 2 includes a rotating driving member 201, a clamping driving member 202 and a clamping unit 203. The rotating driving member 201 is arranged on the film tearing positioning platform 1. The output end of the rotating driving member 201 is connected to the clamping driving member 202. The rotating driving member 201 and the clamping driving member 202 drive the clamping unit 203 to rotate and clamp respectively. During the film tearing process, the clamping unit 203 is a component that actually contacts the bottom film and applies a clamping force, and can stably and reliably clamp the bottom film. The rotating driving member 201 can drive the clamping unit 203 to perform a rotational motion, so that the clamping unit 203 can adjust the direction or angle of the bottom film while clamping the bottom film, thereby improving the film tearing efficiency. The clamping driving member 202 is responsible for driving the clamping unit 203 to perform a clamping action to ensure that the bottom film is firmly clamped during the tearing process. The rotating drive 201 and the clamping drive 202 enable the clamping unit to clamp and rotate automatically, so that the base film can be quickly and accurately separated from the adhesive tape, improving the film tearing quality and efficiency, and reducing the damage and waste of the adhesive tape during the film tearing process. Compared with manual operation, which may cause damage or waste of the adhesive tape due to improper operation, automatic clamping and rotation can reduce such risks and improve the utilization rate of materials.

[0040] Furthermore, the clamping unit 203 includes a first positioning rod 2031, a second positioning rod 2032 and at least two clamping blocks 2033. The first positioning rod 2031 and the second positioning rod 2032 are arranged in parallel, and the two clamping blocks 2033 are arranged opposite to the first positioning rod 2031 and the second positioning rod 2032. When the adhesive tape to be torn off is placed on the film-tearing positioning platform 1, the clamping drive 202 drives the first positioning rod 2031 and the second positioning rod 2032 to approach each other, so that the two clamping blocks 2033 can be accurately aligned to clamp the bottom film of the adhesive tape. Then the film tearing horizontal moving component 3 drives the film tearing positioning platform 1 to approach the film tearing driving component 4. After the film tearing driving component 4 grabs the adhesive tape, the rotating driving component 201 drives the clamping driving component 202 to rotate, so that the first positioning rod 2031 and the second positioning rod 2032 rotate. Then the film tearing horizontal moving component 3 drives the film tearing positioning platform 1 away from the film tearing driving component 4. The bottom film of the adhesive tape is separated from the adhesive tape under the action of the two clamping blocks 2033 and the film tearing driving component 4. Finally, the clamping driving component 202 drives the first positioning rod 2031 and the second positioning rod 2032 to separate, so that the two clamping blocks 2033 are separated, and the bottom film is separated from the film tearing positioning platform 1 without restriction.

[0041] It should be noted that there are four clamping blocks 2033 in this embodiment, two of which are respectively arranged at the two ends of the first positioning rod 2031, and the remaining two clamping blocks 2033 are arranged at the second positioning rod 2032, and are opposite to the two clamping blocks 2033 arranged at the first positioning rod 2031. The four clamping blocks 2033 are respectively located at the two ends of the first positioning rod 2031 and the second positioning rod 2032, forming a stable quadrilateral clamping structure, which can more effectively disperse the clamping force, making the bottom film more stable during the clamping process, and reducing the risk of displacement or falling off due to vibration or external force.

[0042] Please refer to Figure 1The film tearing drive assembly 4 includes a grabbing manipulator 401, a horizontal moving assembly 402 and a vertical moving assembly 403. The horizontal moving assembly 402 drives the vertical moving assembly 403 to drive the grabbing manipulator 401 to move horizontally, and the vertical moving assembly 403 drives the grabbing manipulator 401 to move vertically, so that the grabbing manipulator 401 is close to or away from the film tearing positioning platform 1. The grabbing manipulator 401 is the core component of the film tearing drive assembly 4, which is responsible for directly grabbing and tearing off the bottom film of the adhesive tape. By accurately controlling the movement of the grabbing manipulator 401, efficient and accurate grabbing of the bottom film can be achieved. The horizontal moving assembly 402 is responsible for driving the vertical moving assembly 403 to move in the horizontal direction, so that the grabbing manipulator 401 is close to the film tearing positioning platform 1 in the horizontal direction. At the same time, through the drive of the horizontal moving assembly 402, the grabbing manipulator 401 can be operated in a larger range, thereby expanding the operating range and adaptability of the equipment. The vertical moving assembly 403 is responsible for driving the grabbing manipulator 401 to move in the vertical direction, so as to achieve the accurate grabbing and tearing of the base film by the grabbing manipulator 401. By accurately controlling the movement of the vertical moving assembly 403, it is possible to ensure that the grabbing manipulator 401 operates at the correct position and height. In other words, by the coordinated work of the grabbing manipulator 401, the horizontal moving assembly 402 and the vertical moving assembly 403, and by accurately controlling the movement and action sequence of the grabbing manipulator 401, the horizontal moving assembly 402 and the vertical moving assembly 403, the base film can be efficiently and accurately torn off.

[0043] For details, please refer to Figure 3 , a plurality of suction nozzles 4011 arranged in a matrix are provided on one side of the gripping manipulator 401 close to the film tearing positioning platform 1. The suction nozzles 4011 grab and fix the non-base film part of the adhesive tape by suction to facilitate the tearing of the base film. The suction nozzles 4011 arranged in a matrix mean that the gripping manipulator 401 can apply suction to multiple points of the adhesive tape at the same time, thereby achieving a more stable and efficient gripping, and effectively preventing the adhesive tape from sliding or falling off during the tearing of the base film. At the same time, the suction nozzles 4011 arranged in a matrix can ensure that the base film is subjected to uniform suction during the gripping process, avoiding deformation or damage of the base film caused by excessive force at a single point, and helping to protect the integrity of the base film and the adhesive tape.

[0044] Please refer to Figure 4The film tearing horizontal moving assembly 3 includes a driving member 301, a slider 302 and a guide rod 303. The slider 302 is connected to the film tearing positioning platform 1. The driving member 301 drives the slider 302 to drive the film tearing positioning platform 1 to move horizontally along the guide rod 303. The guide rod 303 provides a stable path for the movement of the slider 302, ensuring that the slider (and then drives the film tearing positioning platform 1) can move smoothly and stably in the horizontal direction. As a power source, the driving member 301 can efficiently drive the slider 302 to move along the guide rod 303, reduce energy loss, improve movement efficiency, and enable the film tearing positioning platform 1 to respond quickly and complete the required horizontal movement. The stable connection between the slider 302 and the film tearing positioning platform 1 ensures the stability and reliability of the platform during the entire movement process. Even under high speed or high load conditions, the film tearing positioning platform 1 can maintain its position and direction unchanged, thereby ensuring the accuracy of the film tearing operation.

[0045] Please refer to Figure 1 , this embodiment further includes a material frame 5, which is arranged on the moving path of the film tearing positioning platform 1. The arrangement of the material frame 5 can conveniently collect the torn bottom film, avoid the bottom film from being scattered, and keep the working environment clean and hygienic. Specifically, the material frame 5 is arranged on the moving path of the film tearing positioning platform 1, and when the bottom film is separated from the film tearing positioning platform 1, it falls into the material frame 5. The operator can directly collect the bottom film in the material frame 5, which reduces labor.

[0046] In addition, the present embodiment further includes an air supply assembly 6, which is disposed adjacent to the material frame 5, and includes a hose 601 and an air nozzle 602 connected to the hose 601. The hose 601 has the characteristic of being bendable in various directions. During the film tearing process, the hose 601 is bent in the direction of film tearing, so that the air nozzle 602 disposed on the hose 601 faces the bottom film, and the air nozzle 602 blows air toward the bottom film, so that the bottom film can smoothly detach from the film tearing positioning platform 1 and fall into the material frame 5.
