[0061] Specifically, as shown in Figure 1 、 Figure 2 And Figure 3 Battery packaging film separation equipment includes conveying unit 1 and separation unit 2. Wherein, conveying unit 1 is used to convey packaging film strip 100, so that packaging film strip 100 moves forward continuously, Figure 1The direction indicated by the middle arrow is the conveying direction of the packaging film strip 100, and the conveying unit 1 conveys the packaging film strip 100 to the separating unit 2 along the horizontal direction. The packaging film strip 100 is arranged with a plurality of battery cells 200 at intervals along the conveying direction, and the packaging film strip 100 is provided with an opening 101 corresponding to each battery cell 200. The battery cell 200 is wrapped in the packaging film strip 100, and the tab 201 of the battery cell 200 can be exposed through the opening 101 on the packaging film strip 100, so as to avoid wrapping the tab 201 of the battery cell 200 by the packaging film strip 100. The separating unit 2 comprises a first driving mechanism 21, a first die 22 and a second die 23 arranged oppositely, and the second die 23 is provided with an insulating layer 2311. The first driving mechanism 21 is in transmission connection with the first die 22, so as to drive the first die 22 to move close to or away from the second die 23. The packaging film strip 100 can pass between the first die 22 and the second die 23 under the conveying of the conveying unit 1, and the tab 201 of the battery cell 200 can be in contact with the insulating layer 2311 on the second die 23 through the opening 101 on the packaging film strip 100. When the first die 22 and the second die 23 are in contact, the packaging film strip 100 is sheared at the periphery of the battery cell 200, so as to shear out a packaging film monomer for wrapping a single battery cell 200. The packaging film monomer wraps the battery cell 200, so as to form a battery.
[0062] Exemplarily, the first die 22 and the second die 23 are stamping dies matched with each other, wherein the first die 22 is an upper die, and the second die 23 is a lower die.
[0063] More specifically, the packaging film strip 100 comprises an upper packaging film and a lower packaging film, and the plurality of battery cells 200 are clamped between the upper packaging film and the lower packaging film. In this way, only the packaging film monomer needs to be continuously sheared out by the first die 22 and the second die 23, so as to realize the separation of the battery and the packaging film strip 100, and improve the production efficiency of the battery.
[0064] Exemplarily, the packaging film strip 100 is an aluminum plastic film, which is commonly used as a packaging structure of the battery.
[0065] The battery packaging film separating device provided by the embodiment of the application continuously conveys the packaging film strip 100 and the plurality of battery cells 200 arranged on the packaging film strip 100 to the separating unit 2 through the conveying unit 1, and the packaging film strip 100 passes between the first die 22 and the second die 23 of the separating unit 2 under the conveying of the conveying unit 1, so as to shear and separate the packaging film strip 100. When the packaging film strip 100 is separated, the first driving mechanism 21 is controlled to drive the first die 22 to move towards the second die 23, until the first die 22 and the second die 23 are in contact and shear the packaging film strip 100 at the periphery of the battery cell 200. The sheared packaging film monomer and the battery cell 200 wrapped by the packaging film monomer constitute a battery, so as to realize the separation of the battery and the packaging film strip 100, and improve the production efficiency.
[0066] Referring to Figure 3 Since the second mold 23 is provided with the insulating layer 2311, the tab 201 of the battery cell 200 can be insulated from the metal part of the second mold 23, and when the first mold 22 and the second mold 23 are in contact to shear the packaging film strip 100, the tab 201 of the battery cell 200 can be prevented from contacting the metal part of the second mold 23 through the opening 101 on the packaging film strip 100, and the battery cell 200 can be prevented from short circuiting during the process of separating the packaging film strip 100, thereby improving production safety and ensuring that the battery production line can continuously and stably produce high-quality battery products.
[0067] In the embodiment of the present application, as shown in Figure 2 and Figure 3 , the first mold 22 is provided with a positioning column, and the packaging film strip 100 is provided with a plurality of positioning holes 102 corresponding to each battery cell 200, the plurality of positioning holes 102 are arranged around the battery cell 200, and the second mold 23 is provided with a relief groove, the positioning column can pass through the positioning hole 102 and extend into the relief groove. By inserting the positioning column on the first mold 22 and the positioning hole 102 on the packaging film strip 100, on the one hand, it is convenient to fix the packaging film strip 100 during stamping and shearing, and to avoid the movement of the packaging film strip 100 during stamping, which can cause poor battery quality, and on the other hand, it can also position the stamping and shearing position to avoid stamping deviation.
[0068] Specifically, the first mold 22 is provided with an upper stamping part, which can be a stamping knife, and cooperates with the second mold 23 to stamp and shear the packaging film strip 100. The lowest point of the positioning column is lower than the lowest point of the upper stamping part, so that when the first mold 22 moves downward to approach the second mold 23, the positioning column first passes through the positioning hole 102 on the packaging film strip 100, and then the first mold 22 continues to move downward under the drive of the first driving mechanism 21, the positioning column gradually extends into the relief groove in the second mold 23, preventing interference between the positioning column and the second mold 23, until the upper stamping part contacts the second mold 23, to complete the stamping and shearing of the packaging film strip 100.
[0069] Exemplarily, the first driving mechanism 21 is a pneumatic cylinder, an oil cylinder, etc.
[0070] Exemplarily, the packaging film strip 100 is provided with four positioning holes 102 corresponding to each battery cell 200, and the four positioning holes 102 are arranged at the four corner positions of the battery cell 200, to achieve better positioning and fixing effect.
[0071] In the embodiment of the present application, as shown in Figure 2As shown, the separating unit 2 further comprises elastic members 24, which are arranged between the first die 22 and the second die 23 and are compressed when the first die 22 moves towards the second die 23. By arranging the elastic members 24, the unbalanced force between the first die 22 and the second die 23 during punching can be alleviated, and the encapsulation film strip 100 is prevented from being unevenly stressed during punching and shearing, so that the shearing quality is improved.
[0072] Further, a plurality of elastic members 24 are arranged between the first die 22 and the second die 23. In this embodiment, four elastic members 24 are arranged at the four corners of the first die 22 and the second die 23, which effectively improves the uniformity of the stress of the encapsulation film strip 100.

The guide rod 232 is connected to the side of the second die seat 231 facing the first die seat 221, and the guide rod 232 is slidably fitted in the guide sleeve 222. The elastic member 24 is sleeved on the guide rod 232 and can abut against the guide sleeve 222.
[0074] When the first driving mechanism 21 drives the first die seat 221 to vertically move, the guide sleeve 222 and the guide rod 232 are in sliding fit in the vertical direction to accurately guide the movement of the first die seat 221, so that the punching precision and quality are improved. When the first die seat 221 moves downward, the guide sleeve 222 pushes the elastic member 24 through the bottom surface thereof to compress the elastic member 24, so that the unbalanced force on the first die 22 is alleviated. Since the elastic member 24 is sleeved on the guide rod 232, the stability of the elastic member 24 is ensured, and the extension and contraction of the elastic member 24 are guided, so that the elastic member 24 stably extends and contracts.
[0075] Further, the guide sleeve 222 and the guide rod 232 are both provided with four and one-to-one corresponding elastic members 24, which are arranged at the four corners of the first die seat 221 and the second die seat 231, so that the guiding precision is effectively ensured, and one elastic member 24 is sleeved on each guide rod 232.

Specifically, when the second driving mechanism 11 drives the transmission rollers 12 to rotate, the transmission rollers 12 drive the packaging film belt 100 to convey forward by the friction between them. The axes of the plurality of transmission rollers 12 are parallel to each other, and can guide the movement of the packaging film belt 100.
[0081] Exemplarily, the plurality of transmission rollers 12 can be in transmission connection by a belt transmission mechanism or the like, so as to rotate synchronously. Further, a driven roller can also be arranged, the packaging film belt 100 is wound around the driven roller, the driven roller is not in transmission connection with the second driving mechanism 11, but rotates under the driving of the packaging film belt 100, and plays a guiding role.

[0083] Referring to Figure 5 The conveying unit 1 further comprises a third driving mechanism 13, a connecting frame 14 and an auxiliary roller 15. The housing of the third driving mechanism 13 is arranged on the rack unit 3; the connecting frame 14 is connected to the output end of the third driving mechanism 13; the auxiliary roller 15 is rotatably connected to the connecting frame 14, and the auxiliary roller 15 is opposite to one of the transmission rollers 12 and is arranged on the opposite side of the packaging film strip 100. The auxiliary roller 15 can be driven by the third driving mechanism 13 to move towards or away from the packaging film strip 100, so that the auxiliary roller 15 can press or release the packaging film strip 100. Specifically, the auxiliary roller 15 is arranged above the packaging film strip 100, and the transmission roller 12 opposite to the auxiliary roller 15 is arranged below the packaging film strip 100. Before conveying the packaging film strip 100, the third driving mechanism 13 is controlled to be started to drive the auxiliary roller 15 to move downward until the auxiliary roller 15 contacts the packaging film strip 100 and presses the packaging film strip 100 on the transmission roller 12 below with a certain pressure, so as to increase the friction between the packaging film strip 100 and the transmission roller 12 below, and the second driving mechanism 11 can smoothly drive the packaging film strip 100 to move, avoiding the phenomenon of slipping between the transmission roller 12 and the packaging film strip 100.
[0084] Further, the third driving mechanism 13 and the auxiliary roller 15 are arranged downstream of the separation unit 2, so as to avoid pressing the packaging film strip 100 before the battery is cut and separated, preventing the battery from being damaged by pressing.
[0085] Exemplarily, the third driving mechanism 13 is a linear driving mechanism such as a pneumatic cylinder or an oil cylinder.
[0086] The battery separated from the packaging film strip 100 by the first die 22 and the second die 23 comprises the battery cell 200 and the packaging film monomer wrapped outside the battery cell 200. After being separated from the packaging film strip 100, the battery needs to be transferred to the next station. Figure 4 The battery packaging film separation device further comprises a transfer unit 4 arranged on the rack unit 3, which is used to pick up the battery on the second die 23 and transfer the battery to a preset station.

The vacuum chuck mechanism 44 is arranged on the mounting frame 43, and is used to suck the battery.
[0088] The conveying unit 1 conveys the packaging film tape 100 to the separation unit 2 along a first horizontal direction. The transfer unit 4 is arranged on one side of the separation unit 2 along a second horizontal direction. The first horizontal direction, the second horizontal direction, and the vertical direction are perpendicular to each other.
[0089] The driving direction of the fourth driving mechanism 41 is along the second horizontal direction, and is used to drive the fifth driving mechanism 42 and the mounting frame 43 to move along the second horizontal direction, so as to approach or move away from the separation unit 2. When the mounting frame 43 moves above the second mold 23, the fifth driving mechanism 42 drives the mounting frame 43 to descend, and the vacuum chuck mechanism 44 generates negative pressure to suck the battery separated on the second mold 23. Subsequently, the mounting frame 43 is driven by the fifth driving mechanism 42 and the fourth driving mechanism 41 to first ascend and then move away from the separation unit 2, until it moves to the preset work station, and then the battery is placed on the preset work station by the vacuum chuck mechanism 44.
