Description

Technical Field

[0001] This utility model relates to the field of battery production and processing technology, specifically to a film cutting and feeding device. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes to generate an electric current. Common batteries include lead-acid batteries, lithium batteries, sodium batteries, and fuel cells. Fuel cells convert the Gibbs free energy portion of the chemical energy of fuel into electrical energy through an electrochemical reaction. They are not limited by the Carnot cycle effect, resulting in high efficiency. Fuel cells use fuel and oxygen as feedstock and have no mechanical transmission parts, thus producing no noise pollution and very few harmful gases. Common fuel cells include hydrogen-oxygen fuel cells, solid oxide fuel cells, and methanol fuel cells. A fuel cell generally includes components such as electrodes, a membrane, and a circuit module. The membrane separates the oxidant and reductant and conducts ions; it is a crucial component that directly affects battery safety and cost. During battery production, the membrane undergoes airtightness testing before it can be used in the battery. Separators are typically wound into rolls and pulled out during use. In traditional operations, the separator is pulled out, tested for air tightness by an airtightness testing device, and then introduced into the battery assembly equipment for slitting. To facilitate assembly, this method requires pulling the separator at the battery assembly equipment end, resulting in a long travel distance for the separator. During the pulling process, deformation is prone to occur, affecting the quality of the separator and potentially leading to product defects. Therefore, a slitting device is needed that can reduce separator deformation and facilitate air tightness testing. Utility Model Content

Detailed Implementation

[0030] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0031] Reference Figures 1 to 6 The present invention provides a film cutting and feeding device, including a frame 1, a feeding mechanism 2, a pulling mechanism 3, a cutting mechanism 4, and a transfer mechanism 5.

[0032] The feeding mechanism 2 is mounted on the frame 1. The feeding mechanism 2 includes a fixed plate 21 mounted on the frame 1, a feeding roller 22 mounted on the fixed plate 21, a receiving assembly 23 mounted on the fixed plate 21, a receiving roller 24 mounted on the fixed plate 21, and a plurality of guide rollers 25 mounted on the fixed plate 21. In this embodiment, both the receiving roller 24 and the feeding roller 22 can be driven by a motor. The number and position of the guide rollers 25 can be adapted according to specific requirements. Additionally, a tensioning roller can be mounted on the fixed plate 21. The tensioning roller is movable and can achieve tension by pulling the diaphragm with its own weight; alternatively, a driving component can be used for active tensioning.

[0033] The receiving assembly 23 includes a receiving platform 231 connected to the fixed plate 21, several pressure rods 232 disposed on the receiving platform 231, and a scraper plate 233 disposed on the receiving platform 231. The diaphragm is covered with a protective film during winding. This protective film needs to be torn off during unwinding. The torn protective film is wound up by the take-up roller 24, and the scraper plate 233 assists in tearing off the protective film. In a specific implementation, the pressure rods 232 can be connected to a cylinder, which presses down on the diaphragm pulled out of the roll under the cylinder's drive. The diaphragm roll is mounted on the unwind roller 22, and after being pulled out at the end, it passes through the guide roller 25, the receiving assembly 23, the slitting mechanism 4, and finally reaches the pulling mechanism 3.

[0034] A material pulling mechanism 3 is mounted on the frame 1. The material pulling mechanism 3 includes a material pulling seat 31 mounted on the frame 1, a first linear module 32 mounted on the material pulling seat 31, and a material pulling assembly 33 connected to the first linear module 32. The material pulling assembly 33 is used to fix the end of the diaphragm. Driven by the first linear module 32, the material pulling assembly 33 moves, thereby pulling out the diaphragm. The length of the diaphragm can be set by setting the driving distance of the first linear module 32.

[0035] The material pulling assembly 33 includes a movable base 331 connected to the first linear module 32, a material pulling bracket 332 disposed on the movable base 331, a first material pulling drive 333 disposed on the material pulling bracket 332, and a suction member 334 connected to the output end of the first material pulling drive 333. The suction member 334 is elongated and covers the width direction of the diaphragm, adsorbing the diaphragm from above.

[0036] The material pulling mechanism 3 further includes a material pulling auxiliary component 34, which includes a second material pulling drive member 341 disposed on the material pulling bracket 332, a top pressing member 342 connected to the second material pulling drive member 341, and a diaphragm located between the suction member 334 and the top pressing member 342. The second material pulling drive member 341 drives the top pressing member 342 to move upward, cooperating with the suction member 334 to clamp the diaphragm, so that the diaphragm is pulled when the first linear module 32 drives the moving seat 331 to move. Several top pressing members 342 can be provided, specifically adapted to the size of the diaphragm. In this embodiment, both the first material pulling drive member 333 and the second material pulling drive member 341 are cylinders.

[0037] The slitting mechanism 4 is mounted on the frame 1, located between the feeding mechanism and the pulling mechanism. The slitting mechanism 4 includes a slitting seat 41 mounted on the frame, a slitting bracket 42 mounted on the slitting seat 41, a cutter assembly 43 movably connected to the slitting bracket 42, and a slitting drive member 44 for driving the cutter assembly 43 to move. The slitting assembly specifically includes a blade holder and a cutter fixed to the blade holder. After the pulling mechanism 3 pulls the diaphragm out a predetermined length, the slitting assembly moves downwards and cuts the diaphragm under the drive of the slitting drive member 44.

[0038] A transfer mechanism 5, disposed on one side of the frame 1, is used to transfer the slit diaphragm to the airtightness testing mechanism. The transfer mechanism 5 includes a transfer support frame 51 disposed on one side of the frame 1, a second linear module 52 disposed on the transfer support frame 51, a vertical module 53 connected to the second linear module 52, and a material-grabbing assembly 54 connected to the vertical module 53. In this embodiment, the first linear module 32 and the second linear module 52 are oriented in the same direction. After the diaphragm is cut, the transfer mechanism 5 can adsorb and transfer the diaphragm to the airtightness testing mechanism.

[0039] The material-grabbing assembly 54 includes a material-grabbing bracket 541 connected to the vertical module 53, and a plurality of suction cups 542 (not all suction cups 542 are shown in the figure) disposed at the bottom of the material-grabbing bracket 541. The suction cups 542 are arranged according to the size of the diaphragm and surround the edge of the diaphragm to ensure that the entire diaphragm can be picked up.

[0040] The slitting mechanism 4 includes a pressing assembly 45, which is located between the slitting bracket 42 and the unloading mechanism 2. The pressing assembly 45 includes a pressing seat 451, a pressing frame 452 disposed on the pressing seat 451, a pressing drive 454 disposed on the pressing frame 452, and a pressing plate 453 connected to the output end of the pressing drive 454. After the pulling mechanism 3 pulls out the diaphragm, the pressing assembly 45 presses down on the diaphragm to prevent it from moving. At this time, the slitting assembly can cut the diaphragm. After the diaphragm is cut, it is moved to the airtightness detection mechanism via the transfer mechanism 5. Then, the pulling mechanism 3 again absorbs the end of the diaphragm, and then the pressing assembly 45 releases the diaphragm, allowing the diaphragm to be pulled out again.

[0041] The film-cutting and feeding device includes a vision component 6, which is located above the slitting mechanism 4. The vision component 6 includes a vision support 61, on which a vision sensor 62 is mounted. This invention also includes a machine cover (not shown in the figure) that encloses all the mechanisms. The vision support 61 is fixed to the top of the machine cover. The vision component 6 can collect image information and monitor the slitting process of the diaphragm. Additionally, ultrasonic sensors, distance sensors, photoelectric sensors, etc., can be installed on the frame 1 to monitor the pulling of the diaphragm.

[0042] The feeding mechanism 3 includes a material loading assembly 35, which includes a material loading plate 351 movably connected to the frame 1, and a material loading drive component 352 mounted on the frame 1 for driving the material loading plate 351 to move. The receiving plate is used to receive the diaphragm, preventing the diaphragm from being unsupported at the bottom. The receiving drive component drives the receiving plate closer to or away from the slitting mechanism 4, thereby avoiding obstruction when the slitting mechanism 4 cuts the diaphragm.

[0043] The transfer device of this utility model is connected to the airtightness testing mechanism, which is located on one side of the frame 1. Specifically, from the attached... Figure 1 The feeding mechanism 2, cutting mechanism 4, pulling mechanism 3, and airtightness testing mechanism are arranged sequentially from left to right, with the transfer mechanism 5 located at the rear of the frame 1. The airtightness testing mechanism includes a frame, a test bracket mounted on the frame, and a test pressure plate movably connected to the test bracket. The test pressure plate can move vertically under the drive of a cylinder. In addition, the frame is also equipped with a movable test seat, which can be moved under the test pressure plate or away from the area where the test pressure plate is located, thereby facilitating the placement and gripping of the diaphragm. It is convenient to place the diaphragm into the test seat and also convenient to transfer the diaphragm away after the test.

[0044] In actual operation, after the diaphragm is pulled out, the protective film on its surface separates from the diaphragm as it passes through the receiving assembly 23, and the protective film is fixed to the receiving roller 24. The diaphragm passes through the tension roller, guide roller 25, and slitting mechanism 4 before reaching the pulling mechanism 3. The pulling mechanism 3 first pulls the diaphragm out to a set length, then the pressing assembly 45 of the slitting mechanism 4 presses the diaphragm and cuts it. After the diaphragm is cut, the pulling mechanism 3 releases the diaphragm and continues to move to make room. The transfer mechanism 5 picks up the diaphragm and moves it to the airtightness testing mechanism. The airtightness testing mechanism performs an airtightness test on the diaphragm. After the test is completed, the diaphragm can be transported to the assembly equipment for cell assembly.

[0045] This utility model is equipped with a feeding mechanism 2, a cutting mechanism 4, and a pulling mechanism 3. It can immediately cut the diaphragm after pulling it out to a set length, that is, the diaphragm is pre-cut into a set size before the airtightness test, so that the distance the diaphragm is pulled is close to the size of the diaphragm, avoiding long-distance pulling of the diaphragm, greatly reducing the deformation of the diaphragm, ensuring the quality of the diaphragm, and thus ensuring the quality of the product. At the same time, after the diaphragm is cut, it can be transferred to the airtightness testing device for testing with the help of the transfer mechanism 5. It is convenient, fast, and realizes automated operation with high efficiency.
