Description

Technical Field

[0001] The utility model relates to the field of battery packaging equipment, in particular to a membrane conveying mechanism. Background Art

[0002] During the battery production process, one of the steps is to encapsulate the battery with aluminum-plastic film. This involves placing the battery on the film, folding the film in half so that it covers the entire battery, and then using a heat sealer to seal two sides of the film, while leaving the other side unsealed. This process requires cutting the film into sheets of a predetermined size and pulling them to the desired location for a robotic arm to grasp. However, existing film handling mechanisms can only handle one sheet of film at a time, resulting in low loading efficiency and failing to meet the demands of high-speed automated production.

[0003] For example, the Chinese invention patent publication number CN108946234A, entitled "Soft Film Transport Mechanism," describes a soft film transport mechanism comprising a drive mechanism, a movable connection assembly, a positioning assembly, and a soft film tray. The soft film tray is positioned at the soft film feeding station, and the positioning assembly is positioned on the movable connection assembly and is used to transport the soft film tray between the soft film feeding station and the imprinting station. While this soft film transport mechanism eliminates the need for manual intervention, reducing labor costs, it can only transport one sheet of soft film at a time, resulting in low film transport efficiency.

[0004] Therefore, there is an urgent need for a mechanism that can quickly transport the film to solve the above problems. Utility Model Content

[0005] (1) Problems to be solved

[0006] The technical problem to be solved by the utility model is to provide a diaphragm conveying mechanism in view of the current status of the existing technology.

[0007] (2) Technical solution

[0008] The present invention is realized through the following technical solutions: The present invention proposes a membrane transport mechanism, which includes a membrane pulling component, a transfer component and a film carrier component. A film suction device is installed below the translation module 2 of the transfer component, and a lifting cylinder is connected below the membrane transfer platform of the film carrier component, and the lifting cylinder is connected to the translation module 3. Driven by the translation module 1, the grabbing claw of the membrane pulling component clamps the first membrane and transports it to the bottom of the transfer component, and then the film suction device moves down to absorb the first membrane. The transfer component drives the film suction device to move and transfer the first membrane to the first placement position of the film carrier component. The grabbing claw of the membrane pulling component pulls the second membrane, and the lifting cylinder lifts the membrane transfer platform and the second membrane is sucked by the suction cup strips distributed on the membrane transfer platform. Driven by the translation module 3, the membrane transfer platform moves back and forth between the two ends of the translation module 3.

[0009] By adopting the above technical solution, the grabbing claw of the film pulling assembly moves to the end of the film sheet to grab the film sheet. The translation module drags the grabbing claw to pull the aluminum-plastic film to the required length. Then, the film suction device of the transfer assembly moves down to absorb the first aluminum-plastic film that has been cut. The film suction device then transports the aluminum-plastic film to the first aluminum film position on the film transfer platform. After that, the grabbing claw grabs the second cut aluminum-plastic film. The film transfer platform of the film carrier assembly moves up and down driven by the lifting cylinder to absorb the second aluminum-plastic film. Finally, the belt module drives the transfer platform carrying the two aluminum-plastic films to move, and the film sheet robot transports the aluminum-plastic film to the next workstation. This utility model can automatically transport two aluminum-plastic films at a time, and the film sheet transportation efficiency is high.

[0010] Furthermore, the film-pulling assembly includes a jaw adjustment block, which is fixedly connected to the first module of the translation module. A dual-slider cylinder is mounted on one end of the jaw adjustment block, which houses an openable and retractable gripping jaw. The jaw adjustment block allows the gripping jaw to be translated perpendicular to the movement path of the module. The translation module utilizes a screw module as its propulsion system.

[0011] Furthermore, the film suction device includes a slide cylinder and a film suction plate. The slide cylinder is fixedly connected to the second slide block of the second translation module. The lower end of the slide cylinder is connected to the first spring buffer block. The first spring buffer block and the second spring buffer block are connected by a spring connecting column. The spring connecting column contains a buffer spring. The film suction plate is mounted on the second spring buffer block. The second translation module uses the second screw module as the carrier power device.

[0012] Furthermore, the module slider 3 of the translation module 3 is fixedly connected to the lifting cylinder, the guide rod end of the lifting cylinder is fixedly connected to the bottom of the film transfer platform, and a plurality of suction cup strips are slidably mounted on the film transfer platform. Among them, the translation module 3 uses a belt module as a carrying power device.

[0013] (3) Beneficial effects

[0014] During operation, the grabbing claw moves to the end of the diaphragm to grab the diaphragm, and the screw module drags the grabbing claw to pull the aluminum-plastic film to the required length. The film suction device is then driven by the screw module to move back and forth, and driven by the slide cylinder to move up and down, sucking the first aluminum-plastic film that has been cut. The film suction device then transports the aluminum-plastic film to the first aluminum film position on the film transfer platform. After that, the grabbing claw grabs the second cut aluminum-plastic film. At this time, the film transfer platform moves up and down driven by the lifting cylinder so that the suction cup bar sucks the second aluminum-plastic film. Finally, the belt module drives the transfer platform carrying the two aluminum-plastic films to move, and the film robot transports the aluminum-plastic film to the next workstation. This utility model realizes the function of automatically transporting two aluminum-plastic films at a time, and the film transportation efficiency is high. Furthermore, this utility model has wide applicability and can be used to handle films of various sizes. The gripper adjustment block features an adjustment slot, which allows it to be adjusted and tightened on the module slider. This allows the gripper to adjust its position to accommodate various sizes of aluminum-plastic film. Correspondingly, the suction cup strips on the film transfer platform are adjusted to accommodate different sizes of aluminum film. When used in battery packaging equipment, this mechanism can improve the integration and production efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
