DETAILED DESCRIPTION

[0022] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0024] In the prior art, lithium and sodium batteries are now widely used in portable batteries such as mobile phones and power sources such as electric tools and electric vehicles. Due to different uses, the soft-packaged lithium batteries using aluminum-plastic composite films have different requirements on the performance and service life of the aluminum-plastic composite films. In the production and processing of aluminum-plastic films, there are disadvantages such as low cutting efficiency and poor cutting effect, and no function of adjusting and controlling the cutting distance.

[0025] In order to solve the above-mentioned technical problems, an embodiment of the present application proposes a soft-pack battery aluminum-plastic film cutting device, in which the aluminum-plastic film is unwound by an aluminum-plastic film unwinding mechanism, and the master-slave transmission mechanism smoothly conveys the unwound aluminum-plastic film, and sends it to the sensing bracket through the cutter assembly. After the sensor senses the aluminum-plastic film, the cutter assembly is controlled to cut it, so as to obtain an aluminum-plastic film of a predetermined size, thereby realizing automatic cutting of the aluminum-plastic film to a fixed length. Next, the soft-pack battery aluminum-plastic film cutting device proposed in the embodiment of the present application is described in detail.

[0026] Please refer to Figure 1 , Figure 1 The schematic diagram of the structure of a soft-pack battery aluminum-plastic film cutting device proposed in an embodiment of the present application is shown, and the device includes a rectangular device bottom plate 1 arranged at the bottom, two support plates 2, an aluminum-plastic film unwinding mechanism, a master-slave transmission mechanism, a cutter assembly 8, a telescopic cylinder 11, an induction bracket 10 and an induction sensor 9;

[0027] Two support plates 2 are arranged at one end of the rectangular device bottom plate 1, the aluminum-plastic film unwinding mechanism is arranged at the top edge of the support plate 2, and the master-slave transmission mechanism is arranged at the middle of the top of the support plate 2 and is lower than the aluminum-plastic film unwinding mechanism;

[0028] The cutter assembly 8 is arranged in the middle of the rectangular device bottom plate 1, and the telescopic cylinder 11 is arranged on the cutter assembly 8;

[0029] The sensing bracket 10 is disposed at the other end of the rectangular device bottom plate 1 , and the sensor 9 is disposed at the middle of the sensing bracket 10 .

[0030] The device can be used for cutting the aluminum-plastic film of soft-pack lithium batteries and sodium batteries, wherein the aluminum-plastic film cutting device for soft-pack batteries is constructed on a rectangular device bottom plate as a stable support base for the entire system, and two support plates 2 are installed at both ends of the bottom plate to support the upper structure. The aluminum-plastic film unwinding mechanism is set at the top edge of the support plate 2, which is responsible for unfolding and providing continuous aluminum-plastic film materials as the starting point of the cutting process.

[0031] The master-slave transmission mechanism is arranged at the middle of the top of the support plate 2, slightly lower than the aluminum-plastic film unwinding mechanism, to ensure that the aluminum-plastic film can be smoothly and accurately transmitted to the cutter assembly 8 to achieve the transmission of power. The cutter assembly 8 is installed in the middle of the base plate for implementing precise cutting actions to cut the aluminum-plastic film to the required size. The cutter assembly 8 is also equipped with a telescopic cylinder 11 to control the precise downward pressure of the cutter or to achieve the adjustment of the cutting pressure. The induction bracket 10 and the sensor 9 are arranged at the other end of the base plate. The induction bracket 10 is equipped with the sensor 9, which is used to monitor the key parameters in the cutting process or as a sensor for positioning and quality control to ensure the accuracy and efficiency of the cutting operation.

[0032] The soft-pack battery aluminum-plastic film cutting device proposed in the embodiment of the present application is reasonably designed, and utilizes the automatic tape feeding functions of the aluminum-plastic film unwinding mechanism and the master-slave transmission mechanism respectively, and adopts the fixed-length cutting function of the sensing device and the cutter assembly 8, to jointly realize the fixed-length automatic cutting of the aluminum-plastic film, and the operation is simple and fast, thereby ensuring the personal safety of the operator and reducing the risk of manual damage to the aluminum-plastic film.

[0033] In a possible implementation, the aluminum-plastic film unwinding mechanism includes two fixed buckles 3 and an air-inflating roller 4 , each fixed buckle 3 is respectively fixed at the top edge of each support plate 2 , and the air-inflating roller 4 is located between the two fixed buckles 3 .

[0034] The two buckles are respectively installed and fixed on the top edge of each support plate 2, and their function is to firmly grasp and position the core shaft of the aluminum-plastic film coil to ensure that the film material can be smoothly and uninterruptedly unfolded during the unwinding process.

[0035] The air-inflating roller 4 is located between the two fixed buckles 3. It is a special winding device that closely adheres to and applies a certain tension to the aluminum-plastic film through gas pressure. When the gas pressure acts, the surface of the roller will expand evenly, so as to be in close contact with the surface of the aluminum-plastic film, which can not only effectively prevent the film material from loosening or wrinkling during the unwinding process, but also adjust the tension of the film when necessary to ensure the stability of unwinding and the accuracy of cutting. Through the coordinated work of the fixed buckle 3 and the air-inflating roller 4, the stable release and tension control of the aluminum-plastic film material are achieved.

[0036] In a possible implementation, the aluminum-plastic film unwinding mechanism further includes a first electric element 13 connected to the inflation roller 4 .

[0037] The first electric element 13 connected to the inflation roller 4 indicates that the unwinding mechanism has a motor drive function. The expansion degree or rotation movement of the inflation roller 4 can be finely adjusted by electric control. It can more accurately control the unwinding speed and tension of the aluminum-plastic film, with fast response speed and high operation accuracy. It can adapt to the needs of automated production lines, reduce manual intervention, and improve the stability and efficiency of overall production.

[0038] In a possible implementation manner, the master-slave transmission mechanism includes a driving roller 5 and a driven roller 6 .

[0039] The driving roller 5 is the driving force source in the transmission system, directly or indirectly receives power, and is driven by the motor, and its rotation drives the movement of the entire transmission chain. The driven roller 6 cooperates with the driving roller 5, and the driven roller 6 rotates with the rotation of the driving roller 5, and the power is transmitted through the friction force or mechanical connection between the two, ensuring that the power of the aluminum-plastic film material is smoothly and stably transmitted to the cutter assembly 8 or other subsequent working parts.

[0040] In a possible implementation, the master-slave transmission mechanism further includes a first pneumatic element 7 and a second electric element 12 , the pneumatic element 7 is connected to the driven roller 6 , and the second electric element 12 is connected to the active roller 5 .

[0041] The pneumatic element 7 connected to the driven roller 6 indicates that the operation of the driven roller 6 can be controlled by air pressure to achieve precise adjustment of the transmission process. The pneumatic system can respond quickly and provide stable and controllable power transmission, which is suitable for situations where flexible adjustment of tension or speed is required. The second electric element 12 connected to the active roller 5 indicates that the drive of the active roller is also controlled by a motor, which can ensure the stability of the transmission and the precise output of power, and is also convenient for fine adjustment of speed and torque through an electronic control system.

[0042] In a possible implementation manner, the device further includes a control cabinet 14 connected to the first electric element 13 , the second electric element 12 , the pneumatic element 7 , the induction head, and the telescopic cylinder 11 .

[0043] The control cabinet 14, as a central control unit, is responsible for coordinating and managing the first electric element 13, the second electric element 12, the pneumatic element 7, the sensor head and the telescopic cylinder 11. The control cabinet 14 collects the data fed back by the sensor, issues instructions after processing, and realizes effective control of each component, such as adjusting the motor speed, controlling the air pressure, managing the activation and detection functions of the sensor head, and operating the telescopic action of the telescopic cylinder 11, thereby ensuring the automation and intelligence of the operation of the entire device.

[0044] In a possible implementation, the two support plates 2 are arranged perpendicular to the rectangular device bottom plate 1 .

[0045] In a possible implementation, the device further includes a slide rail 15 , which is disposed at the other end of the rectangular device bottom plate 1 and contacts the sensing bracket 10 .

[0046] The slide rail 15 is arranged at the other end of the rectangular device bottom plate 1 to provide a smooth and straight guide support for the induction bracket 10. The contact between the slide rail 15 and the induction bracket 10 ensures that the induction bracket 10 can slide stably along the predetermined path when necessary, in order to adjust the position, perform maintenance or adapt to the processing requirements of workpieces of different sizes. Therefore, the addition of the slide rail 15 optimizes the flexibility and maintainability of the device, so that the induction bracket 10 and other components can be easily adjusted according to actual operation requirements, reflecting the consideration of practicality and ease of operation in the design.

[0047] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0048] The soft-pack battery aluminum-plastic film cutting device proposed in the embodiment of the present application is reasonably designed, and utilizes the automatic tape feeding functions of the aluminum-plastic film unwinding mechanism and the master-slave transmission mechanism respectively, and adopts the fixed-length cutting function of the sensing device and the cutter assembly, thereby jointly realizing the fixed-length automatic cutting of the aluminum-plastic film, and the operation is simple and quick, thereby ensuring the personal safety of the operator and reducing the risk of manual damage to the aluminum-plastic film.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
