In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] like Figures 1 to 7 As shown, a battery film coating device of this embodiment includes a feeding mechanism 100, a film coating mechanism 200, a conveying mechanism 300 and a clamping mechanism 400. The feeding mechanism 100 includes a film opening component 110, and the film opening component 110 includes a film opening block 111 for opening the film 700; the film coating mechanism 200 is arranged on one side of the feeding mechanism 100, and the film coating mechanism 200 includes a guide component 210, and the guide component 210 includes a guide head 211, and a guide hole 212 is arranged in the middle of the guide head 211. One side of the guide component 210 is provided with a loading hole for placing the battery 800. The jig 220 is provided with a loading driving member 230 which drives the battery 800 toward the guide head 211 and moves through the guide hole 212; the conveying mechanism 300 is arranged on one side of the feeding mechanism 100 and the film-covering mechanism 200, and the feeding mechanism 100 and the film-covering mechanism 200 are arranged in sequence along the conveying direction of the conveying mechanism 300; the clamping mechanism 400 is arranged on the conveying mechanism 300, and the conveying mechanism 300 drives the clamping mechanism 400 to move back and forth between the feeding mechanism 100 and the film-covering mechanism 200.

[0032] In this embodiment, during the process of loading the film 700, the film 700 is first stretched by the film opening block 111 to achieve pre-stretching of the film 700, and then the pre-stretched film 700 is transported to the film sleeve mechanism 200 for film sleeve. Since the film 700 is already in a stretched state, when the film sleeve mechanism 200 is film sleeved, the battery 800 to be filmed can be easily and smoothly inserted into the film 700, avoiding the occurrence of film jamming, film penetration or film stripping, thereby improving the accuracy of film sleeve and the efficiency of film sleeve. Furthermore, the film sleeve mechanism 200 is also provided with a guide head 211 for guiding the battery 800 to be filmed. Specifically, by first extending the guide head 211 into the film 700, so that the battery 800 to be filmed passes through the guide hole 212 along the guide head 211 and enters the film 700, the positioning and guiding of the film sleeve of the battery 800 to be filmed is achieved through the guide head 211, and accurate film sleeve is achieved. The battery film coating device of this embodiment can effectively improve the accuracy of film coating, thereby facilitating improving operation efficiency and reducing production costs.

[0033] Further, a plurality of guide pieces 213 are arranged around the edge of the guide hole 212 away from the feeding fixture 220, and the plurality of guide pieces 213 are arranged obliquely in a direction away from the feeding fixture 220 and gradually approach the central axis of the guide hole 212, so that the guide head 211 and the guide piece 213 form a truncated cone or a cone shape. By first extending the smaller side into the opening of the film 700, the guide piece 213 and the guide head 211 as a whole can be more easily entered into the film 700, thereby achieving an effective guiding effect. Specifically, the guide piece 213 is an elastic piece. In the process of film sleeve operation, the guide piece 213 is first extended into the opening of the film 700, and then the battery 800 is driven through the guide hole 212 of the guide head 211 by the feeding drive 230, and the guide piece 213 is pushed open to enter the film 700. When the battery 800 is completely entered into the film 700, the guide piece 213 is taken out from the film 700 and restored to the original inclined state, waiting for subsequent operations.

[0034] In one embodiment, the film covering mechanism 200 further includes a sliding seat 240, a second slide rail 250, and a second driving member 260. The second driving member 260 drives the sliding seat 240 to slide on the second slide rail 250 toward or away from the clamping mechanism 400. The loading fixture 220 and the guide head 211 are arranged on the sliding seat 240. In this embodiment, the second driving member 260 drives the guide piece 213 on the guide head 211 to extend into the film 700 on the clamping mechanism 400, thereby achieving a guiding effect on the film covering of the battery 800.

[0035] In one embodiment, the film sleeving mechanism 200 further includes a third driving member 270. The third driving member 270 is disposed on the sliding seat 240, and the third driving member 270 drives the loading jig 220 to move closer to or away from the guiding head 211. In actual operation, an external loading mechanism loads the battery 800 to be sleeved with a film onto the loading jig 220, and then the third driving member 270 drives the loading jig 220 to move closer to the guiding head 211 so that the guiding head 211 can perform subsequent guiding and film sleeving operations on the battery 800.

[0036] Further, a sensor (not shown) for sensing the position of the guiding head 211 is disposed on one side of the loading jig 220 facing the guiding head 211, so that the battery 800 on the loading jig 220 is aligned with the corresponding guiding head 211, that is, the battery 800 is aligned with the guiding hole 212, so that the battery 800 can smoothly pass through the guiding hole 212 under the drive of the loading driving member 230. Among them, the sensor is connected to the third driving member 270. When the sensor senses the position of the guiding head 211, the third driving member 270 stops driving. At this time, the battery 800 is aligned with the guiding hole 212, that is, the central axis of the battery 800 coincides with the central axis of the guiding hole 212.

[0037] In one embodiment, the film opening assembly 110 further includes a support member. The support member is disposed on one side of the film opening block 111, and the support member and the film opening block 111 are arranged in sequence along the conveying direction of the film 700. The support member includes two support rods 112, and the two support rods 112 are spaced apart to form a gap for the film 700 to pass through. When performing the film feeding operation, the film 700 is first passed through the gap between the two support rods 112 to realize the support of the film 700, so that the film opening block 111 disposed on one side of the support rod 112 can expand the film 700.

[0038] In one embodiment, the feeding mechanism 100 further includes a feeding assembly 120. The feeding assembly 120 is disposed on one side of the film opening block 111. The feeding assembly 120 includes a first clamping member 121, a first sliding rail 122, and a first driving member 123. The first driving member 123 drives the first clamping member 121 to slide on the first sliding rail 122. Among them, the film opening block 111 is disposed adjacent to the feeding end of the feeding mechanism 100. One end of the first sliding rail 122 is disposed adjacent to the film opening block 111, and the other end of the first sliding rail 122 is disposed adjacent to the discharging end of the feeding mechanism 100. Specifically, after the film 700 is expanded by the film opening block 111, the film 700 is clamped and fixed by the first clamping member 121, and under the drive of the first driving member 123, the film 700 moves with the first clamping member 121 on the sliding rail to the discharging end of the feeding mechanism 100.

[0039] In actual operation, the feeding assembly 120 further includes a conveying roller 124 and a feeding port 125, and the conveying roller 124 and the feeding port 125 are arranged between the first slide rail 122 and the film opening block 111. The conveying roller 124 includes a first roller 1241 and a second roller 1242. After the film 700 is opened by the film opening block 111, it first passes through the first roller 1241 and the second roller 1242 to slightly close the opened film 700 for subsequent conveying. The slightly closed film 700 passes through the feeding port 125 and enters the feeding assembly 120, and then the first clamping member 121 conveys the film 700 along the first slide rail 122 to the discharge end, and then conveys it to the film sleeving mechanism 200 through the clamping mechanism 400 and the conveying mechanism 300.

[0040] In actual operation, the film opening block 111 is set to be spindle-shaped. One side tip of the spindle shape facilitates easy entry into the film 700, and then the film 700 is opened through the middle part. In order to facilitate subsequent conveying of the opened film 700, the film 700 also needs to be slightly closed by the conveying roller 124. At this time, the other side tip of the spindle-shaped film opening block 111 can cooperate well with the closing of the conveying roller 124, so that the smoothness and smoothness of the film 700 moving on the film opening block 111 are ensured, and the situation that the film opening block 111 causes jamming or even damage to the film 700 is avoided, which is beneficial to ensuring the smooth conveying of the film 700.

[0041] In one embodiment, the feeding mechanism 100 further includes a film cutting assembly 130. The film cutting assembly 130 is arranged at the discharge end of the feeding mechanism 100. There is a discharge port 140 at the discharge end of the feeding mechanism 100. The film cutting assembly 130 includes a film cutting driving member 131 and a cutter member 132. The film cutting driving member 131 drives the cutter member 132 to move towards or away from the discharge port 140. Specifically, the first clamping member 121 conveys the film 700 along the first slide rail 122 to the discharge end and conveys it from the discharge port 140 into the clamping mechanism 400. The clamping mechanism 400 clamps the film 700. At this time, the film cutting driving member 131 drives the cutter member 132 to move towards the discharge port 140 to cut the film 700 at the discharge port 140, so that the clamping mechanism 400 clamps the cut film 700 and conveys it to the film sleeving mechanism 200 along with the conveying mechanism 300.

[0042] Furthermore, during the film cutting operation, the length of the film 700 conveyed by the first clamping member 121 can be controlled according to the actual size of the battery 800 to be sleeved with the film. Thus, when the film cutting assembly 130 cuts the film, a film 700 that conforms to the size of the battery 800 to be sleeved with the film can be obtained, realizing the operation of fixed-length film cutting, which is beneficial to improving the utilization rate of the film 700 and reducing production costs.

[0043] In one embodiment, the film feeding mechanism is further provided with a detection component 150, which is connected to the clamping mechanism 400 and the conveying mechanism 300. The clamping mechanism 400 and the conveying mechanism 300 determine where to clamp and convey the corresponding film according to the detection result of the detection component 150. When the detection component 150 detects that the film 700 is qualified, the clamping mechanism 400 and the conveying mechanism 300 clamp and convey the qualified film 700 to the film covering mechanism 200 for film covering operation. The detection component 150 is arranged on one side of the film opening block 111, and the film opening block 111 and the detection component 150 are sequentially arranged along the conveying direction of the film 700, and are used to detect the film 700. If an unqualified film 700 appears, the unqualified film 700 can be processed in time, so as to avoid using an unqualified film 700 to cover the battery 800, and then removing and re-covering the film on the filmed battery 800, which is time-consuming and labor-intensive.

[0044] By setting the detection component in this embodiment, unqualified films 700 can be identified in advance, which is conducive to processing these unqualified films 700 in advance, and is conducive to improving the smoothness of the overall film covering operation, improving the overall operation efficiency and reducing production costs.

[0045] Specifically, the detection component 150 includes a color sensor, which detects the color of the film 700 through the color sensor, and judges the color difference of the film 700 by comparing it with the standard color, so as to judge whether the color difference of the film 700 is qualified. Of course, in actual operation, the detection component 150 also includes a visual recognition camera (not shown), and the visual recognition camera can also be used to identify whether the film 700 is damaged, so as to judge whether the film 700 is qualified. Further, by arranging the detection component 150 after the film opening block 111, so that after the film 700 is opened by the film opening block 111, the detection component 150 can more clearly detect the color difference of the film 700 or whether it is damaged, which is conducive to improving the accuracy of the detection.

[0046] In one embodiment, the battery film device further includes a waste treatment mechanism 600 for disposing unqualified films 700. The waste treatment mechanism 600 is arranged on one side of the conveying mechanism 300 and is located within the conveying range of the conveying mechanism 300, so that the conveying mechanism 300 conveys the unqualified films 700 to the waste treatment mechanism 600. In addition, the waste treatment mechanism 600 is connected to the detection component 150, so that the detection component 150 feeds back the information of the detected film 700 to the waste treatment mechanism 600. When the detection component 150 detects an unqualified film 700, the conveying mechanism 300 and the clamping mechanism 400 clamp the unqualified film 700 and convey it to the waste treatment mechanism 600, and then the unqualified film 700 is discarded by the waste treatment mechanism 600.

[0047] Specifically, the waste material handling mechanism 600 includes a material taking component 610 and a waste material box 620. The material taking component 610 includes a material taking base 611, a material taking frame 612, and a material taking driving part 613. A material taking suction cup 614 is provided on the material taking frame 612, which is used to suck and remove the unqualified film 700 on the clamping mechanism 400. The material taking driving component drives the material taking frame 612 to move back and forth between the clamping mechanism 400 and the waste material box 620, so as to remove the unqualified film 700 from the clamping mechanism 400 and throw it into the waste material box 620. In this embodiment, the material taking frame 612 is rotatably arranged on the material taking base 611. After the material taking frame 612 sucks and removes the unqualified film 700 from the clamping mechanism 400, the material taking driving part 613 drives the material taking frame 612 to rotate to directly above the opening of the waste material box 620, and stops the suction of the suction cup on the film 700, so that the film 700 directly falls into the waste material box 620 below from the material taking frame 612, and the operation is simple and convenient.

[0048] In one embodiment, the clamping mechanism 400 includes a clamping component 410. The clamping component 410 includes a clamping bottom plate 411, a clamping pressing plate 412, and a clamping driving part 413 that drives the clamping bottom plate 411 and the clamping pressing plate 412 to move relative to each other. The clamping or loosening of the film 700 is realized through the relative movement of the clamping bottom plate 411 and the clamping pressing plate 412. A plurality of claws 4121 are provided on the side of the clamping pressing plate 412 facing the clamping bottom plate 411, which are used to limit and fix the battery 800 after the film sleeving is completed. The clamping bottom plate 411 is provided with an avoidance groove 4111 corresponding to the claws 4121 to prevent the clamping pressing plate 412 and the clamping bottom plate 411 from not being able to fully fit, so that the clamping effect on the film 700 cannot be effectively realized.

[0049] Furthermore, clamping suction cups 4112 are provided on the clamping bottom plate 411 and / or the clamping pressing plate 412 to further ensure the firm clamping of the film 700 by the clamping component 410. And during the film sleeving process, the clamping bottom plate 411 and the clamping pressing plate 412 loosen the clamping of the film 700. At this time, by setting the clamping suction cups 4112 on the clamping bottom plate 411, the film 700 can be adsorbed on the clamping bottom plate 411, so as to keep the film 700 stable during the process of the guiding head 211 and the battery 800 passing through the film 700, thereby ensuring the stability of the film sleeving operation.

[0050] In one embodiment, the clamping mechanism 400 further includes a blanking assembly 420. The blanking assembly 420 includes a blanking slide rail 421 and a blanking driving member 422. The blanking driving member 422 drives the clamping bottom plate 411 to move along a first direction on the blanking slide rail 421. The first direction is perpendicular to the direction in which the clamping bottom plate 411 moves relative to the clamping pressing plate 412. Wherein, after the battery 800 is covered with a film, the film-covered battery 800 is re-clamped by the clamping pressing plate 412 and the clamping bottom plate 411, and is conveyed to the blanking station under the conveyance of the conveying mechanism 300. At this time, the clamping driving member 413 drives the clamping pressing plate 412 and the clamping bottom plate 411 to release the film-covered battery 800, and then the blanking driving member 422 drives the clamping bottom plate 411 to move along the first direction to send the film-covered battery 800 into the blanking station.

[0051] Then, the film-covered battery 800 is taken off by the blanking mechanism 500 at the blanking station to complete the product blanking. Wherein, the blanking mechanism 500 is arranged on one side of the conveying mechanism 300 and within the conveying range of the conveying mechanism 300, so that the film-covered battery 800 can be conveyed to the blanking mechanism 500 at the blanking station under the conveyance of the conveying mechanism 300. Specifically, the blanking mechanism 500 includes a blanking turntable 510, and a plurality of blanking jigs 520 are arranged around the blanking turntable 510. The blanking driving member 422 drives the clamping bottom plate 411 to move into the clamping range of the blanking jig 520, and the film-covered battery 800 is clamped and blanked by the blanking jig 520.
