[0060] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0061] like Figure 1-Figure 4 As shown, the utility model discloses a battery film tearing device. The battery film tearing device includes a main frame 110, a moving component, a film tearing component 120, a fixing unit and a control device (not shown). The film tearing component 120 is movable. In a specific embodiment of the utility model, the main frame 110 can be made of aluminum profiles, which can be anti-corrosive and anti-rust while ensuring the strength of use, and is more suitable for dust-free workshops. The main frame 110 has an internal space. The film tearing component 120 includes a film clamping member 121. The film clamping member 121 has two film clamping members arranged at intervals, and the film clamping member is used to clamp the protective film of the battery.

[0062] According to the utility model, the two film clamping parts of the film clamping component 121 can clamp the protective films on both sides of the battery at the same time and move together to realize double-sided film tearing at the same time, without the need to manually adjust the battery orientation. Each battery only needs to be peeled off once, which reduces the number of film peeling times, improves efficiency, and reduces the labor intensity of personnel.

[0063] In a specific embodiment of the present invention, the moving assembly is movably disposed on the main frame 110. The film tearing assembly 120 is disposed on the moving assembly. Thus, the film tearing assembly 120 can move relative to the main frame 110. In a specific embodiment of the present invention, the main frame 110 includes a top frame 111. The moving assembly is movably disposed on the top frame 111 along a first direction D1. The first direction D1 is an extension direction of the top frame 111.

[0064] The fixing unit includes a fixing assembly 130. The fixing assembly 130 is disposed inside the main frame 110 and is used to fix the battery. In a specific embodiment of the present invention, the fixing assembly 130 is disposed on the bottom frame 115 of the main frame 110. The control device is electrically connected to the moving assembly to control the moving assembly to reciprocate along the first direction D1. In a specific embodiment of the present invention, the control device is, for example, a PLC.

[0065] In a specific embodiment of the present invention, Figure 2As shown, the top frame 111 is inclined to the base 115 of the main frame 110. More preferably, the angle between the top frame 111 and the base 115 is a, 20°≤a≤30°. Since the top frame 111 is inclined to the base 115 of the main frame 110, the top frame 111 has a lower end close to the base 115 and an upper end away from the base 115 along the height direction of the main frame 110. The fixing component 130 is close to the lower end of the top frame 111 along the first direction D1. Thus, after the film tearing component 120 clamps the protective film on both sides of the battery at the lower end of the top frame 111, it moves toward the upper end of the top frame 111 along the first direction D1 with the moving component to complete the film tearing. The inclined setting of the top frame 111 saves more space, and will not interfere with other components during the film tearing process, so that the protective film is not easy to break.

[0066] Specifically, Figure 3 As shown, the moving assembly includes a motor 122 and a transmission member. The motor 122 is electrically connected to the control device and is used to drive the transmission member. In a specific embodiment of the present invention, the transmission member is configured as a film tearing gear 123, and the film tearing gear 123 is sleeved on the motor shaft of the motor 122, and the motor shaft drives the film tearing gear 123 to rotate. The top frame 111 has a guide member extending along the first direction D1, and the transmission member cooperates with the guide member to enable the film tearing assembly 120 to move along the first direction D1. In a specific embodiment of the present invention, the guide member is configured as a film tearing rack 112 (see Figure 2 ), the teeth of the film-tearing rack 112 face downward. The film-tearing gear 123 is meshed with the film-tearing rack 112. Thus, the power for moving the moving assembly comes from the motor 122. Since the film-tearing rack 112 is fixed to the top frame 111, by driving the film-tearing gear 123 meshed with the film-tearing rack 112 to rotate, the moving assembly can be moved along the first direction D1, thereby driving the film-tearing assembly 120 to move. The control device controls the motor 122 shaft to rotate in one direction so that the moving assembly moves away from the fixed assembly 130 to complete the film-tearing. It can also control the motor 122 shaft to rotate in the opposite direction so that the moving assembly approaches the fixed assembly 130 to prepare for the next film-tearing.

[0067] Furthermore, if Figure 2 As shown, the top frame 111 has a sliding portion 113 and a guide rail 114 extending along the first direction D1, that is, the guide rail 114 is parallel to the film tearing rack 112. In the illustrated embodiment, the top frame 111 has two guide rails 114, and the film tearing rack 112 is located between the two guide rails 114. The sliding portion 113 is movably disposed on the guide rail 114, and the sliding portion 113 is connected to the moving component. For example, the sliding portion 113 is fixedly connected to the mounting plate 126 of the moving component (see Figure 3Thus, the moving assembly can be connected to the top frame 111 through the sliding portion 113 and the guide rail 114, and during the reciprocating movement of the moving assembly along the first direction D1, the guide rail 114 can guide the moving assembly to make the moving assembly move smoothly without deviation.

[0068] like Figure 1 As shown, the moving assembly may further include a drag chain 125. One end of the drag chain 125 is connected to the top frame 111, and the other end is connected to the moving assembly, and the drag chain 125 may be located above the guide rail 114. The wires of the motor 122 are accommodated in the drag chain 125. Thus, during the reciprocating movement of the moving assembly, the drag chain 125 may be bent at any position to protect the wires of the motor 122 from being damaged.

[0069] like Figure 3 As shown, the film tearing assembly 120 includes a film tearing body 124. The film clamping member 121 is rotatably disposed on the film tearing body 124. For example, the film clamping member 121 is connected to the film tearing body 124 by a pin shaft, so that the film clamping member 121 can rotate along the first axis AX1. Thus, the orientation of the film clamping member 121 can be adjusted to adapt to different models of batteries.

[0070] In the illustrated embodiment, the film clamping member 121 has two separate film clamping members, that is, the two film clamping members independently control the clamping state or the open state. Each film clamping member clamps the protective film on one side of the battery. It can be understood that the film clamping member 121 can also have two integrally formed film clamping members, that is, the two film clamping members are controlled to be in a clamping state or an open state at the same time to clamp the protective films on both sides of the battery at the same time. The film clamping member 121 can be a quick clamp.

[0071] like Figure 4As shown, the fixing assembly 130 includes a clamping cylinder 131, a clamping rack 132, a clamping gear 133 and a clamping jaw 134. The clamping cylinder 131 is electrically connected to the control device and is used to drive the clamping rack 132 to move in the up and down directions. The clamping gear 133 is meshed with the clamping rack 132. The clamping jaw 134 is fixedly connected to the clamping gear 133 so that the clamping jaw 134 moves between the closed position and the open position. Specifically, the opposite sides of the clamping rack 132 have teeth of the same specification, and accordingly, the two clamping gears 133 are arranged relative to each other and mesh with the corresponding teeth respectively. The two clamping jaws 134 are also arranged relative to each other and are fixedly connected to the corresponding clamping gears 133 respectively. For example, the clamping jaw 134 is coaxially arranged with the clamping gear 133, and both can rotate along the second axis AX2. Thus, the control device can control the clamping cylinder 131 to drive the clamping rack 132 to move upward, so that the clamping gear 133 meshing with the clamping rack 132 rotates in one direction, and drives the clamping jaw 134 to rotate to the open position to break away from the contact with the battery; the control device can also control the clamping cylinder 131 to drive the clamping rack 132 to move downward, so that the clamping gear 133 meshing with the clamping rack 132 rotates in the opposite direction, and drives the clamping jaw 134 to rotate to the closed position to contact the battery, and the clamping jaws 134 on both sides rotate synchronously to contact the battery at the same time to complete the clamping of the battery. The control device can control the movement amplitude of the clamping rack 132 by controlling the clamping cylinder 131, and then control the rotation angle of the clamping jaws 134 on both sides, so that the clamping force of the clamping jaw 134 can be adjusted, the mechanical performance is stable, and the clamping is ensured to be firm.

[0072] In one embodiment, at least three groups of fixing assemblies 130 are arranged along the first direction D1, that is, the battery can be clamped from at least three positions. The battery film tearing device also includes a position sensor (not shown) for sensing the position of the film tearing assembly 120. The position sensor is electrically connected to the control device. In the film tearing process when the film tearing assembly 120 is away from the fixing assembly 130, when the film tearing point reaches the clamping position, it is necessary to open the clamping jaws 134 so that the protective film is not clamped by the clamping jaws 134, but can continue to be torn off. Therefore, when the film tearing assembly 120 moves to a predetermined position, the position sensor transmits the position signal of the film tearing assembly 120 to the control device, and the control device controls the corresponding clamping cylinder 131 in response to the position signal to drive the clamping rack 132 to move upward, thereby opening the clamping jaws 134 on both sides, while the other clamping jaws 134 remain in a closed position to fix the battery. After the protective film at the clamping position is torn off, the control device controls the clamping jaws 134 to close to clamp the battery in response to the position signal of the position sensor. Therefore, the clamping jaws 134 will not affect the continuity of film tearing, and through the cooperation between the multiple clamping jaws 134, when one clamping jaw 134 is in the open position, the other clamping jaws 134 are in the closed position, so that the battery is always fixed and will not be skewed.

[0073] like Figure 4 As shown, the fixing unit further includes a lifting assembly 140. The lifting assembly 140 and the fixing assembly 130 are arranged alternately in sequence along the first direction D1. In other words, the heights of the lifting assembly 140 and the fixing assembly 130 are in the same horizontal plane, and the arrangement direction is the same as the moving direction of the film tearing assembly 120. For example, at least three lifting assemblies 140 and at least three fixing assemblies 130 are arranged alternately in sequence along the first direction D1 as lifting assembly 140, fixing assembly 130, lifting assembly 140, fixing assembly 130, lifting assembly 140, fixing assembly 130... The number of lifting assemblies 140 and fixing assemblies 130 can be adjusted according to the length of the battery.

[0074] Specifically, the lifting assembly 140 includes a lifting cylinder 141 and a guide groove 142. The lifting cylinder 141 is electrically connected to the control device and is used to drive the guide groove 142 to move in the up and down directions. When the battery is loaded, the control device controls the lifting cylinder 141 to drive the guide groove 142 to move upward so that it is in the rising position, and the battery is pushed into the guide groove 142 near the outside of the main frame 110 until it reaches the predetermined position. When the film tearing assembly 120 starts to move to tear the film, the control device controls the lifting cylinder 141 to drive the guide groove 142 to move downward so that it is in the descending position to avoid interfering with the protective film of the battery and affecting the continuity of the film tearing.

[0075] Transverse rollers are provided on both sides of the top of the guide groove 142. When the battery is pushed into the guide groove 142, both sides of the battery contact the transverse rollers to slide along the first direction D1. Therefore, when the battery is loaded, the transverse rollers can guide the battery to move and fix it to a predetermined position without deflection, and can also prevent the battery from colliding with the side wall of the guide groove 142.

[0076] like Figure 1As shown, the fixing unit also includes a limit assembly 150. The limit assembly 150 is adjacent to the fixing assembly 130 and is close to the inside of the main frame 110 along the first direction D1, that is, the limit assembly 150 is close to the upper end of the top frame 111 along the first direction D1, and is used to limit the position of the battery along the first direction D1. In the illustrated embodiment, the limit assembly 150 is adjacent to the fixing assembly 130 that is closest to the inside of the main frame 110 among the three fixing assemblies 130. When the battery is loaded, one end of the battery contacts the limit assembly 150, indicating that it is installed to the predetermined position and can no longer move along the first direction D1. Since the positive and negative poles of the battery have different protrusions, the limit assembly 150 can be provided with a groove that matches one of the poles, so that when the battery is loaded, only the matching pole contacts the limit assembly 150 to fix the battery smoothly, otherwise interference will occur. As a result, the limit assembly 150 can ensure that the battery is located at the predetermined position, and can also ensure that the positive and negative poles of the battery will not be reversed, so that all batteries are fixed in the same direction for easy management. In the illustrated embodiment, the workflow of battery film tearing is as follows:

[0077] The personnel pushes the battery from the outermost lifting assembly 140 along the first direction D1 until it contacts the limit assembly 150. The control device controls the motor 122 to drive the moving assembly to move and drive the film tearing assembly 120 to approach the fixed assembly 130 and stop at the preparation position. The personnel tear off part of the protective film on both sides of the battery, and make the film clamping member 121 clamp the protective film on both sides of the battery. The control device controls the lifting cylinder 141 to drive the guide groove 142 to move downward, and controls the clamping cylinder 131 to drive the clamping claw 134 to clamp the battery. At the same time, it controls the moving assembly to move and drive the film tearing assembly 120 away from the fixed assembly 130 to start film tearing. During the film tearing process, the control device also controls the clamping claw 134 to open or close in response to the position signal of the position sensor. After completing the film tearing, the personnel can load the battery for the next time and repeat the above process in a reciprocating cycle.

[0078] The battery film peeling equipment can peel the film of multiple batteries at the same time, such as Figure 1 As shown, the battery film tearing device includes at least two sets of film tearing assemblies 120 arranged at intervals and at least two sets of fixed units arranged at intervals. The number of film tearing assemblies 120 corresponds to the number of fixed units. At least two sets of film tearing assemblies 120 can be set in the mobile assembly. Thus, each batch can tear the film of multiple batteries, further improving efficiency.
