Description

Technical Field

[0001] The present application belongs to the technical field of lithium battery production equipment, and in particular, relates to a film tearing assembly and a film tearing mechanism. Background Art

[0002] The battery module is formed by stacking multiple battery cells. Spacers (such as mica sheets) need to be installed between two adjacent battery cells. The spacers can play the role of insulation, fire prevention and heat insulation. The surface of the spacers is usually covered with a protective film for protecting the spacers. Therefore, the protective film needs to be torn off before the spacers are installed.

[0003] In order to realize automated production, currently, most of the separators with protective films are transported to the film tearing station through a conveying mechanism, and then the film tearing end of the film to be torn off is clamped by the film tearing assembly, and then the transverse movement mechanism drives the separator to move to tear the film. The existing film tearing assembly usually includes a rotating part, on which a group of clamping assemblies for clamping the film tearing end of the film to be torn off are installed. In the initial state, the clamping assembly is in a preset film clamping position. After the film tearing assembly tears off the protective film of the previous separator, the rotating part needs to drive the clamping assembly to rotate to the film releasing position to release the torn protective film, and then the rotating part drives the clamping assembly to rotate to the film clamping position to clamp the film tearing end of the next separator to be torn off. Obviously, this method has the disadvantage of low film tearing efficiency and cannot meet the production requirements of fast beats. Utility Model Content

[0063] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0064] In the automated production of battery cell modules, the diaphragm with the protective film is mostly transported to the film tearing station by a conveying mechanism, and then the film tearing end of the film to be torn off is clamped by the film tearing assembly, and then the transverse mechanism drives the diaphragm to move to implement the film tearing. However, the existing film tearing mechanism usually includes a rotating part, on which a group of clamping assemblies for clamping the film tearing end of the film to be torn off are installed. In the initial state, the clamping assembly is in a preset film clamping position. After the film tearing assembly tears off the protective film of the previous diaphragm, the rotating part needs to drive the clamping assembly to rotate to the film releasing position to release the torn protective film, and then the rotating part drives the clamping assembly to rotate to the film clamping position to clamp the film tearing end of the film to be torn off of the next diaphragm. Obviously, this method has the disadvantage of low film tearing efficiency and cannot meet the production requirements of fast beats.

[0065] Therefore, this application proposes a film tearing assembly, please refer to Figure 1 As shown, a film tearing assembly provided in an embodiment of the present application includes a base 1, a first driving member 10, a rotating member 11 and at least two sets of clamping assemblies 12, wherein: the rotating member 11 is rotatably mounted on the base 1, the fixed end of the first driving member 10 is mounted on the base 1, the driving end of the first driving member 10 is connected to the rotating member 11, and the first driving member 10 is configured to drive the rotating member 11 to rotate relative to the base 1; at least two sets of clamping assemblies 12 are circumferentially spaced apart and the first driving member 10 drives the rotating member 11 to rotate, so as to drive at least two sets of clamping assemblies 12 to move alternately to the film clamping position; when the clamping assembly 12 is in the film clamping position, the clamping assembly 12 is configured to clamp the film tearing end of the film to be torn off on the material at the film tearing station; after the clamping assembly 12 leaves the clamping position, the clamping assembly 12 is also configured to release the torn film.

[0066] Specifically, the film tearing assembly provided in the embodiment of the present application includes two sets of clamping assemblies 12, and the angle between the two sets of clamping assemblies 12 is 180°.

[0067] Optionally, the film tearing assembly may include three sets of clamping assemblies 12, and the angle between each set of clamping assemblies 12 is 120°. Of course, the clamping assemblies 12 may also be arranged in three groups, and the number of the clamping assemblies 12 is not further limited herein.

[0068] It can be seen that the film tearing assembly proposed in the present application is provided with at least two sets of clamping assemblies 12 on the rotating member 11. When the first driving member 10 drives the rotating member 11 to rotate, it drives at least two sets of clamping assemblies 12 to move alternately to the film clamping position to clamp the film tearing end of the film to be torn off on the material in the film tearing station to implement film tearing, which greatly shortens the interval time between film tearing of the previous material and the next material, improves the film tearing efficiency, and can meet the fast-beat production requirements.

[0069] See also Figures 1 to 3 As shown, as an embodiment, the end of the film to be torn off on the material is reserved with two tearing ends extending out of the material, and each set of clamping components 12 includes two clamping members 120 arranged at intervals. When the clamping component 12 clamps the film to be torn off on the material, each clamping member 120 clamps a tearing end correspondingly.

[0075] It can be seen that the second end of the rotating member 11 is rotatably mounted on the base 1 through the slip ring 13, which can prevent the wires and air pipes required by the clamping assembly 12 from being entangled when rotating, and facilitates the arrangement of the wires and air pipes required by the clamping assembly 12.

[0076] Specifically, the first driving member 10 includes a first motor 100, a first pulley 101, a second pulley 102, and a transmission belt 103. The first motor 100 is fixed on the base 1, the output shaft of the first motor 100 is coaxially connected to the first pulley 101, the second pulley 102 is coaxially connected to the rotating shaft of the first end of the rotating member 11, and the transmission belt 103 is sleeved on the first pulley 101 and the second pulley 102.

[0078] The film tearing assembly provided in the embodiment of the present application has the following advantages:

[0079] 1) By setting at least two sets of clamping assemblies 12, when tearing the film, at least two sets of clamping assemblies 12 are driven to move alternately to the film clamping position to clamp the film tearing end of the film to be torn off on the material in the film tearing station to implement film tearing, which greatly shortens the interval time between film tearing of the previous material and the next material, improves the film tearing efficiency, and can meet the fast-beat production requirements.

[0080] 2) The clamping assembly 12 respectively clamps the film to be torn off on the material through two clamping members 120 and has two reserved film tearing ends, which improves the reliability of clamping the film to be torn off on the material and is conducive to improving the success rate of film tearing.

[0081] 3) A first detection member 121 is provided to detect whether there is film residue on the material.

[0082] 4) The second end of the rotating member 11 is rotatably mounted on the base 1 through a slip ring 13, so as to facilitate the arrangement of the wires and air pipes required by the clamping assembly 12.

[0083] See also Figure 4 As shown, the present application also provides a film tearing mechanism for tearing off a protective film on a material, the protective film comprising a base film attached to the bottom surface of the material, the film tearing mechanism comprising a loading component 2, a transfer platform 3, a transfer component 4 and a first film tearing component 5, the first film tearing component 5 being the above-mentioned film tearing component, wherein: the loading component 2 is configured to pick up the material with the protective film and move the picked-up material with the protective film to the transfer platform 3; the transfer platform 3 is at least configured to carry the material with the protective film; the first film tearing component 5 is arranged on one side of the transfer platform 3 and close to the film tearing end of the base film, the first film tearing component 5 is configured to clamp the film tearing end of the base film to be torn off on the material on the transfer platform 3 or release the torn base film; after the first film tearing component 5 clamps the base film to be torn off on the material on the transfer platform 3, the transfer component 4 is configured to pick up the material on the transfer platform 3 and drive the material to move to tear off the base film on the material.

[0084] Specifically, a plurality of negative pressure adsorption holes are provided on the transfer platform 3 , and the material with the protective film is adsorbed and fixed on the transfer platform 3 through the negative pressure adsorption holes.

[0085] It can be seen that the film tearing mechanism proposed in the present application realizes automatic tearing of the bottom film of the material through the cooperation of the feeding component 2, the transfer platform 3, the transfer component 4 and the first film tearing component 5, and the film tearing efficiency is high; at the same time, at least two sets of clamping components 12 of the first film tearing component 5 can be alternately moved to the film clamping position to clamp the film tearing end of the film to be torn off on the material in the film tearing station, so as to cooperate with the transfer component 4 to implement film tearing, which greatly shortens the interval time between film tearing of the previous material and the next material, further improves the film tearing efficiency, and can meet the fast-beat production requirements.

[0087] It can be seen that by setting the sorting component 6, the material with the bottom film torn off can be automatically sorted before mounting, so as to ensure the position accuracy of the material with the bottom film torn off picked up by the blanking component 7, thereby improving the accuracy of the material mounted on the battery cell; by setting the blanking component 7, the material with the bottom film torn off can be automatically mounted on the battery cell, and the mounting efficiency is high.

[0088] See also Figure 1 and Figure 5 As shown, as an embodiment, the film clamping position is located obliquely below the transfer platform 3, and the film tearing mechanism also includes a film pressing assembly 8, which is configured to fold the tearing end of the bottom film to be torn off on the material on the transfer platform 3 downward, so that the clamping assembly 12 of the first film tearing assembly 5 can clamp the tearing end of the bottom film to be torn off on the material on the transfer platform 3.

[0089] Specifically, two sets of film pressing components 8 are provided, and each set of film pressing components 8 corresponds to a film tearing end of the bottom film to be torn off on the material.

[0090] It can be seen that by setting the film clamping position at an angle below the transfer platform 3, the tearing end of the bottom film to be torn off on the material on the transfer platform 3 is folded downward by the film pressing component 8, so that the tearing end of the bottom film to be torn off on the material is closer to the clamping component 12, which makes it easier for the clamping component 12 to quickly and accurately clamp the tearing end of the bottom film to be torn off on the material, which is beneficial to improving the tearing efficiency.
