[0002] When processing some easily damaged materials, a layer of protective material is usually attached to the surface of the material, such as foam, rubber pad, etc. In order to facilitate the transportation of the foam that has not been installed, a layer of isolation film is attached to the surface of the foam, and the end of the isolation film has a tearing end protruding from the foam to facilitate the subsequent tearing of the isolation film.

[0003] In order to realize automated production, currently, the protective material with the isolation film is mostly transported to the film tearing station through a conveyor line, and then the film tearing end of the isolation film is clamped by a clamping assembly, and finally the clamping assembly is driven to slide by a driving member to tear off the isolation film. The existing clamping assembly is driven by a double-headed cylinder to drive two clamping claws to clamp the film tearing end of the isolation film, and then the clamping claws slide horizontally to peel the isolation film from the foam. However, the swing amplitude of the clamping claw driven by the double-headed cylinder is small, and the opening angle of the two clamping claws is small. In continuous automatic production, the isolation film may not be clamped. Utility Model Content

[0054] 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.

[0055] When processing some easily damaged materials, a layer of protective material is usually attached to the surface of the material, such as foam, rubber pad, etc. In order to facilitate the transportation of the foam that has not been installed, a layer of isolation film is attached to the surface of the foam, and the end of the isolation film has a tearing end protruding from the foam to facilitate the subsequent tearing of the isolation film.

[0056] In order to realize automated production, currently, the protective material with the isolation film is mostly transported to the film tearing station through a conveyor line, and then the film tearing end of the isolation film is clamped by a clamping assembly, and finally the clamping assembly is driven to slide by a driving member to tear off the isolation film. The existing clamping assembly is driven by a double-headed cylinder to drive two clamping claws to clamp the film tearing end of the isolation film, and then the clamping claws slide horizontally to peel the isolation film from the foam. However, the swing amplitude of the clamping claw driven by the double-headed cylinder is small, and the opening angle of the two clamping claws is small. In continuous automatic production, the isolation film may not be clamped.

[0057] Therefore, the present application proposes a film tearing clamp 10, see Figure 1As shown, the film tearing clamp 10 proposed in the embodiment of the present application includes a pressure-bearing member 11, a first driving member 12 and a clamping member 13; a first clamping portion 110 is provided on the pressure-bearing member 11, and the clamping member 13 is hinged on the pressure-bearing member 11; the fixed end of the first driving member 12 is hinged to the second end of the pressure-bearing member 11, and the driving end of the first driving member 12 is hinged to the clamping member 13, and the first end of the clamping member 13 is provided with a second clamping portion 130, and the first driving member 12 is configured to drive the clamping member 13 to rotate relative to the pressure-bearing member 11 to drive the second clamping portion 130 of the clamping member 13 to approach or move away from the first clamping portion 110; the first driving member 12 drives the second clamping portion 130 to approach and abut against the first clamping portion 110 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 to loosen the torn film.

[0058] It can be seen that the film tearing clamp 10 proposed in the present application is provided with a first clamping portion 110 on the pressure-bearing member 11 and a second clamping portion 130 on the clamping member 13, and the first driving member 12 drives the clamping member 13 to rotate, thereby driving the second clamping portion 130 to approach and abut against the first clamping portion 110, so as to clamp the film tearing end of the film to be torn off; the clamping member 13 is driven to rotate by a single first driving member 12, and the rotatable space of the clamping member 13 is increased as much as possible within a limited space. Therefore, compared with the film tearing clamp of the prior art, the opening angle of the clamp is increased, ensuring that the film tearing end of the film to be torn off can be accurately clamped during continuous automatic production.

[0059] The film tearing clamp 10 proposed in the present application includes two embodiments, which are described in detail below:

[0060] First embodiment of the film tearing jaw 10

[0061] Please refer again Figure 1 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 pressure-bearing member 11, the second end of the clamping member 13 is hinged to the driving end of the first driving member 12, 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.

[0062] Specifically, the first driving member 12 is a cylinder, and the first driving member 12 is disposed above the pressure-bearing member 11 . The fixed end of the first driving member 12 is hinged to the second end of the pressure-bearing member 11 through a pin shaft.

[0063] Specifically, a receiving cavity 20 is provided on the end surface of the first end of the pressure-bearing member 11, and the corner of the clamping member 13 is hinged in the receiving cavity 20 through a pin shaft, which can reduce the space occupied by installing the clamping member 13 while ensuring stable and reliable movement of the clamping member 13.

[0064] Specifically, the first clamping portion 110 is located on the bottom surface of the first end of the pressure-bearing member 11 , and the second clamping portion 130 is located below the pressure-bearing member 11 .

[0065] It can be seen that by setting the clamping member 13 as a "V"-shaped structure and hinged the corner of the clamping member 13 to the first end of the pressure-bearing member 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, thereby providing a film tearing claw 10 that clamps the film tearing end of the film to be torn off from bottom to top; 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.

[0066] As an implementation manner, the first clamping portion 110 is configured as a slope surface inclined from the first end to the second end of the pressure-bearing member 11 , and the driving stroke of the first driving member 12 is greater than the rotation stroke of the clamping member 13 .

[0067] It can be seen that by setting the first clamping portion 110 as an inclined slope surface, the reliability of the clamping member 13 in clamping the film to be torn off is further improved, and at the same time, the tearing end of the clamped film to be torn off can be tilted upward, which is beneficial to the subsequent film tearing; by making the driving stroke of the first driving member 12 greater than the rotational stroke of the clamping member 13, the reliability of the clamping of the clamping member 13 is ensured.

[0068] Second embodiment of the film tearing jaw 10

[0069] See also 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 driving end of the first driving member 12, the second end of the clamping member 13 is hinged to the pressure-bearing member 11, and the first clamping portion 110 is located at the first end of the pressure-bearing member 11.

[0070] Specifically, the first driving member 12 is a cylinder, and the first driving member 12 is disposed above the pressure-bearing member 11 . The fixed end of the first driving member 12 is hinged to the second end of the pressure-bearing member 11 through a pin shaft.

[0071] Specifically, a receiving cavity 20 is provided in the middle of the pressure-bearing member 11, and the corners of the clamping member 13 are hinged in the receiving cavity 20 through a pin shaft, which can reduce the space occupied by installing the clamping member 13 while ensuring stable and reliable movement of the clamping member 13.

[0072] Specifically, the first clamping portion 110 is located on an end surface of a first end of the pressure-bearing member 11 , and the second clamping portion 130 is located above the pressure-bearing member 11 .

[0073] 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 pressure-bearing member 11, it is achieved that when the first driving member 12 drives the corner of the clamping member 13 to rotate, it drives the second clamping part 130 to move closer to or away from the first clamping part 110, thereby providing a film tearing claw 10 for clamping the tearing end of the film to be torn off from top to bottom.

[0074] As an implementation manner, the first clamping portion 110 is configured as a step surface 111 , and the length of the step surface 111 is smaller than the length of the film tearing end of the film.

[0075] It can be seen that, through the cooperation between the step surface 111 and the clamping member 13, a part of the film tearing end is clamped at the connection between the step surface 111 and the pressure-bearing member 11, so as to further clamp the film tearing end and improve the reliability of clamping.

[0076] The film tearing clamp proposed in the embodiment of the present application has the following advantages:

[0077] 1) The clamping member is driven to rotate by a single first driving member, thereby increasing the rotational space of the clamping member as much as possible within a limited space, increasing the opening angle of the clamping jaws, and ensuring that the tearing end of the film to be torn off can be accurately clamped during continuous automatic production;

[0078] 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;

[0079] 3) The first clamping portion is configured as an inclined slope surface, which not only improves the reliability of the clamping member clamping the film to be torn off, but also enables the film tearing end of the clamped film to be torn off to be tilted upward, which is beneficial to the subsequent film tearing;

[0080] 4) The pressure-bearing member is provided with an accommodating cavity, and the clamping member is hinged in the accommodating cavity, which can reduce the space occupied by installing the clamping member while ensuring stable and reliable movement of the clamping member;

[0081] 5) The first clamping portion is set as a step surface, which improves the reliability of clamping;

[0082] 6) By hingedly connecting the fixed end of the first driving member to the second end of the pressure-bearing member, when the first driving member drives the clamping member to rotate, the fixed end of the first driving member can cooperate with the rotation, thereby ensuring smooth movement of the clamping member.

[0083] See also Figure 3As shown, the present application also proposes a film tearing mechanism. The film tearing mechanism proposed in the embodiment of the present application includes a frame 40, a transfer mechanism and the above-mentioned film tearing jaw 10, the transfer mechanism is installed on the frame 40, and the driving end of the transfer mechanism is connected to the film tearing jaw 10; the transfer mechanism is configured to drive the film tearing jaw 10 to move to a preset position so as to clamp the film to be torn off on the material through the film tearing jaw 10; the transfer mechanism is also configured to drive the film tearing jaw 10 and the film to be torn off clamped by the film tearing jaw 10 to move relative to the material, so as to tear off the film to be torn off clamped by the film tearing jaw 10.

[0084] It should be noted that the material involved in the present application is the foam coated on the surface of the battery cell 30, and the membrane involved in the present application is the isolation membrane coated on the surface of the foam.

[0085] It can be seen that through the cooperation of the transfer mechanism and the film tearing jaw 10, the automatic clamping and tearing of the film to be torn off on the material is realized. At the same time, the film tearing jaw 10 has a large opening angle to ensure that the film tearing end of the film to be torn off can be accurately clamped during continuous automatic production.

[0086] The transfer mechanism of the film tearing mechanism proposed in this application includes two embodiments, which are described in detail below:

[0087] The first embodiment of the transfer mechanism of the film tearing mechanism

[0088] See also Figures 3 to 5 As shown, as an embodiment, the transfer mechanism includes a second drive member 50, a lifting drive member 60 and a first cantilever 70, the fixed end of the lifting drive member 60 is connected to the driving end of the second drive member 50, and the second drive member 50 is configured to drive the lifting drive member 60 along a first horizontal direction ( Figure 3 The driving end of the lifting drive member 60 is connected to the first cantilever 70, and the first cantilever 70 moves back and forth along the second horizontal direction ( Figure 3 The lifting drive member 60 is configured to drive the first cantilever 70 to rise and fall, and at least one film tearing clamp 10 is installed on the first cantilever 70.

[0089] Specifically, the second driving member 50 includes a motor 51, a first pulley 52, a second pulley 53, a transmission belt 54 and a first transverse displacement seat 55. The first pulley 52 and the second pulley 53 are installed on the frame 40 at intervals along the first horizontal direction. The fixed end of the motor 51 is installed on the frame 40. The driving end of the motor 51 is connected to the first pulley 52. ​​The motor 51 is configured to drive the first pulley 52 to rotate. The transmission belt 54 is connected to the first pulley 52 and the second pulley 53. The first transverse displacement seat 55 is fixedly connected to the transmission belt 54. The lifting driving member 60 includes a first linear module 61 and a lifting member 62. The first linear module 61 is installed on the first transverse displacement seat 55 along the vertical direction. The driving end of the first linear module 61 is connected to the lifting member 62. The first cantilever 70 is fixed on the lifting member 62.

[0090] Specifically, the first pulley 52 and the second pulley 53 are both synchronous pulleys, and the transmission belt 54 is a synchronous belt.

[0091] It can be seen that, through the cooperation of the second driving member 50, the lifting driving member 60 and the first cantilever 70, the film tearing jaw 10 is driven to move horizontally and lift up and down, so as to clamp the film tearing end of the film to be torn off and implement film tearing.

[0092] As an implementation manner, the film tearing jaw 10 is installed on the first cantilever 70 in an adjustable manner along the second horizontal direction, and the pressure-bearing member 11 of the film tearing jaw 10 is detachably assembled with the first cantilever 70 .

[0093] Specifically, a mounting hole 700 extending along the second horizontal direction is opened on the first cantilever 70, and the pressure-bearing member 11 of the film tearing jaw 10 is detachably fixed to the first cantilever 70 through the cooperation of a locking member and the mounting hole 700, thereby adjusting the installation position of the film tearing jaw 10 in the mounting hole 700 to adjust the installation position of the film tearing jaw 10 on the first cantilever 70.

[0094] It can be seen that by adjusting the installation position of the film tearing jaw 10 on the first cantilever 70 along the second horizontal direction, the film tearing of battery cells of different sizes is achieved, and the compatibility of the film tearing mechanism is further improved.

[0095] When the transfer mechanism in this embodiment is tearing off the film: the second driving member 50 cooperates with the lifting driving member 60 to move the film tearing jaw 10 to a preset position, the film tearing jaw 10 clamps the film tearing end of the film to be torn off, and the second driving member 50 drives the film tearing jaw 10 to translate relative to the material along the first horizontal direction to tear off the film to be torn off clamped by the film tearing jaw 10; or while the second driving member 50 drives the film tearing jaw 10 to translate relative to the material along the first horizontal direction, the lifting driving member 60 drives the film tearing jaw 10 to move upward to tear off the film to be torn off clamped by the film tearing jaw 10.

[0096] Second embodiment of the transfer mechanism of the film tearing mechanism

[0097] See also Figure 6 As shown, as an embodiment, the transfer mechanism includes a third driving member 80, a rotating driving member 90 and a second cantilever 71, the fixed end of the rotating driving member 90 is connected to the driving end of the third driving member 70, and the third driving member 80 is configured to drive the rotating driving member 80 along the first horizontal direction ( Figure 6 The driving end of the rotary drive member 90 is connected to the second cantilever 71, and the second cantilever 71 moves back and forth along the second horizontal direction ( Figure 6 The rotary drive member 90 is configured to drive the second cantilever 71 to rotate a preset angle, and at least one film tearing clamp 10 is installed on the second cantilever 71.

[0098] It can be seen that through the cooperation of the third driving member 80, the rotating driving member 90 and the second cantilever 71, the film tearing jaw 10 is driven to move horizontally and rotate. The film tearing jaw 10 rotates a preset angle after tearing the film, so that the torn film is vertically downward, which is convenient for releasing the torn film.

[0099] As an embodiment, the third driving member 80 includes a second linear module 81 and a second transverse seat 82, the second linear module 81 extends along the first horizontal direction, and the driving end of the second linear module 81 is connected to the second transverse seat 82; the rotating driving member 90 includes a rotating cylinder 91 and a rotating member 92, the fixed end of the rotating cylinder 91 is installed on the second transverse seat 82, the driving end of the rotating cylinder 91 is connected to the rotating member 92, and the second cantilever 71 is fixed on the rotating member 92.

[0100] It can be seen that through the cooperation of the second linear module 81 and the second transverse seat 82, the rotating cylinder 91 is driven to reciprocate along the first horizontal direction, and through the cooperation of the rotating cylinder 91 and the rotating member 92, the second cantilever 71 is driven to rotate; a third driving member 80 with a simple structure, low cost, stable and reliable operation is provided.

[0101] When the transfer mechanism in this embodiment is tearing the film: the third driving member 80 drives the film tearing jaw 10 to move to a preset position along the first horizontal direction, and the film tearing jaw 10 clamps the film tearing end of the film to be torn off. The third driving member 80 then drives the film tearing jaw 10 to translate relative to the material along the first horizontal direction to tear off the film to be torn off clamped by the film tearing jaw 10. Then the rotating driving member 90 drives the film tearing jaw 10 to rotate downward by 90°, so that the torn film is vertically downward, and the film tearing jaw 10 is released, and the torn film falls by its own weight.

[0102] The film tearing mechanism proposed in the embodiment of the present application has the following advantages:

[0103] 1) The automatic clamping and tearing of the film to be torn off on the material is realized. At the same time, the film tearing jaw has a large opening angle, which ensures that the film tearing end of the film to be torn off can be accurately clamped during continuous automatic production, thereby improving the success rate of the film tearing operation;

[0104] 2) The transfer mechanism can drive the film tearing jaws to move horizontally and up and down, so as to facilitate the film tearing while clamping the film tearing end of the film to be torn off;

[0105] 3) The transfer mechanism can drive the film tearing jaw to move horizontally and rotate. The film tearing jaw rotates to a preset angle after tearing the film, so that the torn film is vertically downward, which is convenient for releasing the torn film.

[0106] The above embodiments are only to illustrate the basic principles and characteristics of the present application. The present application is not limited by the above examples. Without departing from the spirit and scope of the present application, the present application may be subject to various changes and modifications, which are within the scope of the present application to be protected. The scope of protection claimed in the present application is defined by the attached claims and their equivalents.
