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 clamping assembly and a film tearing device. 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 diaphragms with protective films are transported to the film tearing station through a conveyor line, and then the film tearing is carried out through a film tearing device. The existing film tearing device usually includes a transfer module and a clamping assembly. When tearing the film, the transfer module first drives the clamping assembly to move to a height corresponding to the protective film to be torn off, and then the transfer module drives the clamping assembly to move horizontally close to the protective film to be torn off to a preset position. The clamping assembly clamps the tearing end of the protective film to be torn off, and finally drives the clamping assembly to slide through the transfer module to tear off the protective film. Obviously, when clamping the protective film, the existing film tearing device needs the transfer module to drive the clamping assembly to perform two actions, lifting and horizontal movement, which has the disadvantage of cumbersome movements, resulting in low film tearing efficiency of the film tearing device.

[0045] 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.

[0046] 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.

[0047] In order to realize automated production, currently most of the diaphragms with protective films are transported to the film tearing station through a conveyor line, and then the film tearing is carried out through a film tearing device. The existing film tearing device usually includes a transfer module and a clamping assembly. When tearing the film, the transfer module first drives the clamping assembly to move to a height corresponding to the protective film to be torn off, and then the transfer module drives the clamping assembly to move horizontally close to the protective film to be torn off to a preset position. The clamping assembly clamps the tearing end of the protective film to be torn off, and finally drives the clamping assembly to slide through the transfer module to tear off the protective film. Obviously, when clamping the protective film, the existing film tearing device needs the transfer module to drive the clamping assembly to perform two actions, lifting and horizontal movement, which has the disadvantage of cumbersome movements, resulting in low film tearing efficiency of the film tearing device.

[0048] Therefore, the present application proposes a film tearing clamping assembly 10, see Figure 1As shown, the film tearing clamping assembly 10 proposed in the embodiment of the present application includes a base 11, a first driving member 12 and a clamping member 13. The first end of the base 11 is provided with a first clamping portion 110, the clamping member 13 is hinged on the base 11, and the first end of the clamping member 13 is provided with a second clamping portion 130; the fixed end of the first driving member 12 is hinged at the second end of the base 11, and the driving end of the first driving member 12 is hinged to the clamping member 13. The first driving member 12 is configured to drive the clamping member 13 to rotate relative to the base 11 to drive the second clamping portion 130 of the clamping member 13 to approach or move away from the first clamping portion 110 along an arc motion trajectory; the first driving member 12 drives the second clamping portion 130 to approach and abut against the first clamping portion 110 along an arc motion trajectory to clamp the film to be torn off; the first driving member 12 drives the second clamping portion 130 to move away from the first clamping portion 110 along an arc motion trajectory to loosen the torn film.

[0049] It can be seen that the film tearing clamping assembly 10 proposed in the present application drives the clamping member 13 to rotate through the first driving member 12, so that the second clamping part 130 moves in an arc trajectory toward the first clamping part 110 and abuts against the first clamping part 110, so as to clamp the film tearing end of the film to be torn off; compared with the clamping assembly in the prior art, because the second clamping part 130 moves in an arc trajectory, the second clamping part 130 can simultaneously achieve horizontal and vertical displacements. When clamping the film tearing end of the film to be torn off, there is no need to separately drive the clamping assembly to move laterally toward the film tearing end of the film to be torn off, which simplifies the action process of the clamping assembly clamping the film tearing end of the film to be torn off, thereby improving the film tearing efficiency.

[0050] See also Figure 1 Hehe Figure 2 As shown, as an embodiment, the clamping member 13 is a "V"-shaped structure as a whole, the corner of the clamping member 13 is hinged to the first end of the base 11, the driving end of the first driving member 12 is hinged to the second end of the clamping member 13, and the distance from the first end of the clamping member 13 to the corner of the clamping member 13 is smaller than the distance from the second end of the clamping member 13 to the corner of the clamping member 13.

[0051] Specifically, the first driving member 12 is a cylinder, and a fixed end of the first driving member 12 is hinged to the second end of the base 11 through a pin.

[0052] Specifically, the first clamping portion 110 is located on the bottom surface of the first end of the base 11 , and the second clamping portion 130 is located below the base 11 .

[0053] It can be seen that by setting the clamping member 13 to a "V"-shaped structure and hinge the corner of the clamping member 13 to the first end of the base 11, it is achieved that when the first driving member 12 drives the second end of the clamping member 13 to rotate, the second clamping part 130 is driven to move closer to or away from the first clamping part 110 to clamp the film to be torn off or loosen the torn film; at the same time, the distance from the first end of the clamping member 13 to the corner of the clamping member 13 is set to be smaller than the distance from the second end of the clamping member 13 to the corner of the clamping member 13, thereby improving the clamping force of the clamping member 13 and ensuring the reliability of clamping the film to be torn off. Of course, the clamping member 13 can also be designed as a semicircular arc or other special shapes, and the shape of the clamping member is not limited here.

[0054] As an embodiment, the clamping member 13 is a "V"-shaped structure as a whole, the corner of the clamping member 13 is hinged to the driving end of the first driving member 12, the second end of the clamping member 13 is hinged to the base 11, and the first clamping portion 110 is located at the first end of the base 11.

[0055] It can be seen that by setting the clamping member 13 as a "V"-shaped structure and hingedly connecting the corner of the clamping member 13 to the driving end of the first driving member 12, and hingedly connecting the second end of the clamping member 13 to the base 11, it is achieved that when the first driving member 12 drives the corner of the clamping member 13 to rotate, the second clamping part 130 is driven to move closer to or away from the first clamping part 110 to clamp the film to be torn off or loosen the torn film, thereby providing another form of mounting structure for the clamping member 13.

[0056] As an implementation manner, at least one clamping groove 111 is formed on the clamping surface of the first clamping portion 110 , and at least one clamping ridge 131 is formed on the clamping surface of the second clamping portion 130 , and each clamping ridge 131 corresponds to one clamping groove 111 .

[0057] Specifically, a clamping groove 111 is formed on the clamping surface of the first clamping portion 110 , and a clamping ridge 131 is formed on the clamping surface of the second clamping portion 130 .

[0058] It can be seen that, through the cooperation of the clamping groove 111 and the clamping ridge 131, after the film to be torn off is clamped, the tearing end of the film to be torn off is stuck in the clamping groove 111, further clamping the film to be torn off, and improving the reliability of clamping. At the same time, the clamping groove 111 and the clamping ridge 131 are both provided with a line, which can greatly reduce the tensile force on the film to be torn off during clamping while improving the reliability of clamping, reduce the stretching amount of the clamped film, and avoid breaking the film to be torn off when performing the film tearing action. Of course, according to the material of the film to be torn off or the actual process requirements, the number of the clamping grooves 111 and the clamping ridges 131 can be adaptively adjusted.

[0059] As an implementation manner, at least one clamping ridge 131 is disposed on the clamping surface of the first clamping portion 110 , and at least one clamping groove 111 is opened on the clamping surface of the second clamping portion 130 , and each clamping ridge 131 corresponds to a clamping groove 111 .

[0060] It can be seen that by arranging the clamping ridge 131 on the first clamping portion 110 and the clamping groove 111 on the second clamping portion 130, another arrangement form of the clamping groove 111 and the clamping ridge 131 is provided; at the same time, through the cooperation of the clamping groove 111 and the clamping ridge 131, after clamping the film to be torn off, the tearing end of the film to be torn off is stuck in the clamping groove 111, further clamping the film to be torn off, thereby improving the reliability of clamping.

[0061] As an implementation manner, the first driving member 12 and the clamping member 13 are installed on the same side of the base 11 .

[0062] It can be seen that by installing the first driving member 12 and the clamping member 13 on the same side of the base 11, the space occupied by the entire clamping assembly is reduced and the layout is reasonable.

[0063] The film tearing clamping assembly proposed in the embodiment of the present application has the following advantages:

[0064] 1) The first driving member drives the clamping member to rotate, so that the second clamping portion moves toward the first clamping portion in an arc trajectory and abuts against the first clamping portion, so as to clamp the tearing end of the film to be torn off; because the second clamping portion moves in an arc trajectory, the second clamping portion can simultaneously achieve horizontal and vertical displacements. When clamping the tearing end of the film to be torn off, there is no need to separately drive the clamping assembly to move laterally toward the tearing end of the film to be torn off, which simplifies the action process of the clamping assembly clamping the tearing end of the film to be torn off, thereby improving the tearing efficiency;

[0065] 2) The distance from the first end of the clamping member to the corner of the clamping member is set to be smaller than the distance from the second end of the clamping member to the corner of the clamping member, thereby increasing the clamping force of the clamping member and ensuring the reliability of clamping the film to be torn off;

[0066] 3) A clamping groove is provided on the clamping surface of the first clamping part, and a clamping ridge is provided on the clamping surface of the second clamping part, which improves the clamping reliability and reduces the tensile force on the film to be torn off during clamping, thereby avoiding breaking the film to be torn off;

[0067] 4) By hingedly connecting the fixed end of the first driving member to the second end of the pressure-bearing member, the fixed end of the first driving member can cooperate with the rotation when the first driving member drives the clamping member to rotate, thereby ensuring smooth movement of the clamping member;

[0068] 5) Through the design of the clamping grooves and clamping ridges on the first clamping part and the second clamping part, in combination with the driving force provided by the first driving member, the clamping member can provide a more stable and powerful clamping force.

[0069] See also Figure 1 and Figure 3 As shown, the present application also proposes a film tearing device. The film tearing device proposed in the embodiment of the present application includes a transfer component and the above-mentioned film tearing clamping component 10, and the driving end of the transfer component is connected to at least one film tearing clamping component 10; the transfer component is configured to drive the film tearing clamping component 10 to move to a preset position, and the preset position is a position that is at the same height as the film to be torn off and has a preset distance from the film tearing end of the film to be torn off in the horizontal direction, so as to clamp the film tearing end of the film to be torn off on the material through the film tearing clamping component 10; the transfer component is also configured to drive the film tearing clamping component 10 and the film to be torn off clamped by the film tearing clamping component 10 to move relative to the material, so as to tear off the film to be torn off clamped by the film tearing clamping component 10.

[0070] It should be noted that the material involved in the present application is a separator between two battery cells (usually a mica sheet), and the film involved in the present application is a protective film coated on the surface of the separator.

[0071] It can be seen that through the cooperation of the transfer assembly and the film tearing clamping assembly 10, the automatic clamping and tearing of the film to be torn off on the material is realized. At the same time, the second clamping part 130 of the film tearing clamping assembly 10 can simultaneously realize horizontal and vertical displacement when clamping the film to be torn off, which simplifies the action process of the clamping assembly clamping the film to be torn off and improves the film tearing efficiency.

[0072] As an embodiment, the transfer assembly includes a second drive member 20 and a lifting drive member 30, the fixed end of the lifting drive member 30 is installed at the driving end of the second drive member 20, and the second drive member 20 is configured to drive the lifting drive member 30 along the first horizontal direction ( Figure 3 The driving end of the lifting drive member 30 is connected to at least one film tearing clamping assembly 10, and the lifting drive member 30 is configured to drive at least one film tearing clamping assembly 10 to rise and fall.

[0073] When the transfer assembly in this embodiment is tearing off the film: the second driving member 20 cooperates with the lifting driving member 30 to move at least one film tearing clamping assembly 10 to a preset position, at least one film tearing clamping assembly 10 clamps the film tearing end of the film to be torn off, and the second driving member 20 drives at least one film tearing clamping assembly 10 to translate relative to the material along the first horizontal direction to tear off the film to be torn off clamped by at least one film tearing clamping assembly 10; or while the second driving member 20 drives at least one film tearing clamping assembly 10 to translate relative to the material along the first horizontal direction, the lifting driving member 30 drives at least one film tearing clamping assembly 10 to move upward to tear off the film to be torn off clamped by at least one film tearing clamping assembly 10.

[0074] It can be seen that through the cooperation of the second driving member 20 and the lifting driving member 30, at least one film tearing clamping assembly 10 is driven to move horizontally and lift along the first horizontal direction, which is convenient for clamping the film tearing end of the film to be torn off and also for implementing the film tearing.

[0076] It can be seen that by setting the third driving member 40, at least one film tearing clamping assembly 10 can be driven to move laterally along the second horizontal direction, thereby realizing the three-axis transfer of at least one film tearing clamping assembly 10 along the first horizontal direction, the second horizontal direction and the vertical direction. At the same time, at least one film tearing clamping assembly 10 moves along the second horizontal direction to realize film tearing for materials of different sizes, thereby improving the compatibility of the film tearing device. In addition, at least one film tearing clamping assembly 10 can tear the film along the diagonal direction, thereby improving the film tearing effect of the film tearing device.

[0077] As an embodiment, the second driving member 20 includes a motor 21, a first pulley 22, a second pulley 23, a transmission belt 24 and a first transverse member 25. The first pulley 22 and the second pulley 23 are arranged at intervals along the first horizontal direction. The driving end of the motor 21 is connected to the first pulley 22, and the motor 21 is configured to drive the first pulley 22 to rotate. The transmission belt 24 is connected to the first pulley 22 and the second pulley 23, and the first transverse member 25 is fixedly connected to the transmission belt 24; the lifting driving member 30 includes a lifting module 31 and a lifting member (not shown in the figure), the fixed end of the lifting module 31 is installed on the first transverse member 25, and the driving end of the lifting module 31 is connected to the lifting member; the third driving member 40 includes a cylinder 41 and a second transverse member 42, the fixed end of the cylinder 41 is installed on the lifting member, the piston rod of the cylinder 41 is connected to the second transverse member 42, and at least one film tearing clamping assembly 10 is installed on the second transverse member 42.

[0078] Specifically, the first pulley 22 and the second pulley 23 are both synchronous pulleys, the transmission belt 24 is a synchronous belt, and the lifting module 31 is a linear module.

[0079] It can be seen that through the cooperation of the motor 21, the first pulley 22, the second pulley 23, the transmission belt 24 and the first transverse member 25, a second driving member 20 with stable and reliable operation and precise stroke control is provided; through the cooperation of the lifting module 31 and the lifting member, the lifting member is driven to lift and lower, thereby driving the cylinder 41 to lift and lower; through the cooperation of the cylinder 41 and the second transverse member 42, the second transverse member 42 is driven to move laterally along the second horizontal direction, thereby driving at least one film tearing clamping assembly 10 to move laterally along the second horizontal direction, providing a third driving member 40 with a simple structure and low cost.
