[0031] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated in conjunction with specific embodiments below, but is not limited thereto.

[0032] like Figures 1 to 12 This is a drawing of the present invention.

[0033] In the production of battery cell film, it is often necessary to set a film on the film sheet to distinguish different types of battery cells or to paste labels. Therefore, another unloading mechanism is used to paste the film on the film sheet, and then wrap it on the battery cell together with the film sheet.

[0034] So, if Figure 1 As shown, a double feeding device 60 is provided on the film coating device. The double feeding device 60 includes a discharge mechanism 20 (in this embodiment, referred to as a second discharge mechanism 62). It also includes a first discharge mechanism 61, and a cutting mechanism 30 provided at the discharge ends of the first discharge mechanism 61 and the second discharge mechanism 62.

[0035] Preferably, a base 10 is also included.

[0036] like Figure 2 — Figure 3 As shown, the first unloading mechanism 61 includes a first bracket 611, an unloading assembly 612 disposed on the first bracket 611, a cutting assembly 613 disposed at the unloading end of the unloading assembly 612, and a transfer assembly 614 disposed at the unloading end of the cutting assembly 613. The transfer assembly 614 is located at the feeding end of the cutting assembly 613. The rolled film 3 is placed on the unloading assembly 612, and is continuously unloaded under the action of the unloading assembly 612, and the film 3 is cut into a set length by the cutting assembly 613, and then the transfer assembly 614 transfers the film 3 to the film wrapping sheet 2 of the cutting mechanism 30.

[0037] like Figure 4 As shown, the discharging assembly 612 includes a discharging power member 6121 fixed to the first bracket 611, a discharging roller 6122 connected to the power output end of the discharging power member 6121 and used to place the material belt, and a plurality of rollers 6123 rotatably connected to the first bracket 611. The discharging roller 6122 discharges the material, and passes through the rollers 6123 to reach the feeding end of the cutting assembly 613.

[0038] Specifically, the discharge power member 6121 is a linear power member, preferably a cylinder. A pulling roller 6124 is also provided at the power output end of the linear power member. The pulling roller 6124 is provided with at least one idler roller 6123 on the feed side and the discharge side (in this embodiment, one idler roller 6123 is provided on the feed side, and two idlers 6123 are provided on the discharge side). The pulling roller 6124 is located between the discharge roller 6122 and the idler roller 6123, and the linear power member moves to drive the pulling roller 6124 to squeeze the material belt so that the discharge roller 6122 discharges the material. Since the discharge power member 6121 is a linear power member, one end of the material belt is fixed by the cutting component 613, and the other end is placed on the discharge roller 6122 in a roll. When the pulling roller 6124 is pushed downward, the rolled material belt placed on the discharge roller 6122 will rotate to discharge the material. The linear power member descends to the bottom, and then the linear power member shrinks and rises, thereby forming a discharge.

[0039] The cutting assembly 613 includes a mounting plate 6131 for fixing the first bracket 611, a fixed pressing member 6132 fixed to the mounting plate 6131, and a movable pressing member 6133 slidably connected to the mounting plate 6131. ​​The movable pressing member 6133 is arranged on one side of the fixed pressing member 6132. A cutting member 6134 is arranged between the fixed pressing member 6132 and the movable pressing member 6133. The cutting member 6134 is provided with a cutting power member, and a cutting knife is provided at the power output end of the cutting power member. The cutting assembly 613 is arranged at the discharge end of the discharge assembly 612.

[0041] The movable clamping member 6133 is arranged at the power output end of the sliding power member 6138. The movable clamping member 6133 is provided with a movable clamping power member 6139. The power output end of the movable clamping power member 6139 is provided with a first clamping block 6911 and a second clamping block 6912, and the first clamping block 6911 and the second clamping block 6912 have opposite movements. The first clamping block 6911 is rotatably connected with a clamping rod 6913, and a protrusion is provided on the surface of the clamping rod 6913 so that the film 3 can be better bitten when the film 3 is compressed. The second clamping block 6912 is provided with a clamping strip 6914. Among them, the clamping strip 6914 is used to protect the surface of the film 3 when the film 3 is compressed to avoid damage to the film 3.

[0042] like Figure 5 As shown, the transfer assembly 614 includes a mounting frame 6141, a lateral moving member 6142 disposed on the mounting frame 6141, and a vertical moving member 6143 disposed on the lateral moving member 6142. The vertical moving member 6143 is provided with a plurality of suction blocks 6144 connected to the vacuum generating device. Preferably, in order to improve production efficiency, there are three suction blocks 6144.

[0043] Specifically, the vertical moving member 6143 is provided with a vertical power member (a cylinder). The suction block 6144 is provided at the power output end of the vertical power member. The horizontal moving member 6142 includes a motor, a screw rod fixedly connected to the power output end of the motor, and a transmission nut connected to the screw rod. The vertical moving member 6143 is fixedly connected to the transmission nut.

[0044] Preferably, the lateral moving member 6142 is slidably connected to the slide rail provided on the mounting frame 6141 to maintain the accuracy and stability of the lateral movement. The power output end of the vertical power member of the vertical moving member 6143 is provided with a vertical guide column 6145 slidably connected to the lateral moving member 6142 to ensure the stability of the vertical movement.

[0045] Specifically, when discharging the material, the movable pressing member 6133 is close to the side of the fixed pressing member 6132, and the first pressing block 6911 and the second pressing block 6912 move toward each other to bite the film 3. At this time, the first fixed block 6136 and the second fixed block 6137 move away from each other to loosen the film 3; the movable pressing member 6133 moves a set distance under the action of the sliding power member 6138, and then the first fixed block 6136 and the second fixed block 6137 move toward each other to clamp the film 3; the cutting member 6134 drives the cutter to cut the film 3; the vertical moving member 6143 drives the suction block 6144 to move downward, and the suction block 6144 sucks the cut film 3, and then under the action of the horizontal moving member 6142, it is transferred to the top of the cutting mechanism; the vertical moving member 6143 descends to attach the film 3 of the suction block 6144 to the packaging sheet 2.

[0046] like Figure 6 As shown, the cutting assembly 34 includes a sliding plate 341 slidably connected to the upper side of the horizontal plate 325, a mounting block 342 fixed to the sliding plate 341, and a cutting power member 343 (a cylinder) fixed to the mounting block 342. The power output end of the cutting power member 343 is provided with a cutting knife 344 for cutting the film 3. The sliding plate 341 is fixed to a parallel power member 345 (a cylinder), and the parallel power member 345 pushes the sliding plate 341 to move parallel to the feeding direction of the film 2, so that the cutting knife 344 moves parallel to the feeding direction of the film 3, and then adjusts the cutting position of the cutting knife 344 on the film 3. Among them, the cutting power member 343 drives the cutting knife 344 to move perpendicular to the feeding direction of the film 3, so that the cutting knife 344 cuts the film 3. The number of cutting knives 344 should be equal to the number of suction blocks 6144, and they are arranged in parallel on the horizontal plate 325.

[0047] Preferably, the cutting knife 344 is arranged on a side of the second pressing plate 323 close to the enclosing mechanism 40 .

[0048] Preferably, since there are three suction blocks 6144 as described above, the number of cutting knives 344 is also three.

[0049] Preferably, the second pressing plate 323 is provided with a plurality of air holes connected to the vacuum generator on one side close to the enveloping mechanism 40. The air holes are close to the cutting knife 346 so that the air holes can suck and fix the film 3, and the cutting knife 346 can smoothly cut the film 3.

[0050] The cutting mechanism 30 includes a first pressing assembly 31 near the discharge end, a second pressing assembly 32 near one end of the encapsulating mechanism 40, and a cross-cutting assembly 33 arranged between the first pressing assembly 31 and the second pressing assembly 32. The cross-cutting assembly 33 includes a cross-cutting power member 331 and a cross-cutting knife 332 fixed to the power output end of the cross-cutting power member 331. The cross-cutting knife 332 is arranged between the first pressing assembly 31 and the second pressing assembly 32. Among them, the cross-cutting assembly 33 also includes a cross-cutting frame 333, and the cross-cutting frame 333 is installed at the upper end of the first pressing assembly 31. Preferably, the cross-cutting power member 331 is a rodless cylinder, and a moving plate is provided at the power output end, and the cross-cutting knife 332 is installed at the lower end of the moving plate. The cross-cutting power member 331 drives the cross-cutting knife 332 to move perpendicular to the feeding direction of the encapsulating sheet 2. After the first pressing assembly 31 and the second pressing assembly 32 press the film sheet 2 , the cross-cutting knife 332 moves horizontally to cut the film sheet 2 .

[0051] Specifically, the first pressing assembly 31 includes a fixed pressing frame 311, a first pressing power member 312 (cylinder) fixed to the fixed pressing frame 311, and a first pressing plate 313 fixed to the power output end of the first pressing power member 312. The first pressing plate 313 is provided with a guide column 314 slidably connected to the fixed pressing frame 311, so that the first pressing plate 313 moves smoothly, so that the first pressing plate 313 and the coating sheet 2 are in better contact. A pad 315 is provided on the lower side of the first pressing plate 313, so that the coating sheet 2 passes between the first pressing plate 313 and the pad 315. Under the action of the first pressing power member 312, the first pressing plate 313 moves downward and presses the coating sheet 2 against the upper surface of the pad 315. The cross-cutting power member 331 is fixed to the upper end of the fixed pressing frame 311.

[0052] Specifically, the second pressing assembly 32 includes a movable pressing frame 321, a mobile power member 322 (cylinder) fixed to the movable pressing frame 321, and a second pressing plate 323 fixed to the power output end of the mobile power member 322. The movable pressing frame 321 is fixed to the power output end of the adjustable power member 324, so that the second pressing mechanism 32 moves in the feeding direction to adjust the distance between the second pressing plate 323 and the enclosing mechanism 40 and the first pressing mechanism 31. The second pressing plate 323 is provided with a pressing bevel near one end of the enclosing mechanism 40. The pressing bevel of the second pressing plate 323 can better guide the coating sheet 2 to fit on the surface of the workpiece. The pressing bevel contacts the surface of the rotating workpiece on the enclosing mechanism 40 to make the coating sheet 2 close to the surface of the workpiece, thereby making the coating sheet 2 better fit on the workpiece. The interaction between the pressing inclined surface of the second pressing plate 323 and the pressing roller 44 of the encapsulating mechanism 40 enables the encapsulating sheet 2 to be attached to the surface of the workpiece more efficiently, accurately and smoothly, thereby avoiding residual bubbles.

[0053] Among them, the movable press frame 321 is slidably connected to the slide rail provided on the base 10, and the upper side of the movable press frame 321 is slidably connected to the slide rail provided on the fixed press frame 311. The movable press frame 321 is slidably connected to the slide rail both above and below, which is conducive to the smooth and accurate movement of the movable press frame 321. In addition, the adjusting power member 324 is a motor and a screw rod member. The screw rod is fixed to the power output end of the motor, and the movable press frame 321 is fixed to the transmission nut of the screw rod. The rotary motion of the motor drives the movable press frame 321 to move linearly. The movable press frame 321 moves linearly, driving the second pressing plate 323 to approach or move away from the enclosing mechanism 40, thereby making the pressing inclined surface approach or move away from the workpiece.

[0054] The second pressing plate 323 moves up and down relative to the movable material pressing frame 321 to adjust the horizontal position of the second pressing plate 323 and the first pressing plate 313 to facilitate the passage of the film-coated sheet 2. Specifically, a movable power member 322 is provided on both sides of the movable material pressing frame 321, and the movable power member 322 is fixedly connected to the second pressing plate 323 through a provided transverse plate 325. The second pressing plate 323 is arranged below the transverse plate 325 and is fixedly connected to the transverse plate 325. Guide pillars slidably connected to the movable material pressing frame 321 are provided at both ends of the transverse plate 325 to ensure the smooth movement of the second pressing plate 323.

[0055] The second material pressing assembly 32 further includes a power pressing plate 327 provided between the cross plate 325 and the second pressing plate 323, and the power pressing plate 327 is fixedly connected to the power output end of the second material pressing power member 326 provided on the upper side of the cross plate 325. A gap is provided between the power pressing plate 327 and the second pressing plate 323 for passing the film-coating sheet 2. The second material pressing power member 326 drives the power pressing plate 327 to move toward the second pressing plate 323 to compress the film-coating sheet 2. The first material pressing assembly 31 located on one side of the cross-cutting assembly 33 compresses the film-coating sheet 2, and the second material pressing assembly 32 located on the other side of the cross-cutting assembly 33 also compresses the film-coating sheet 2, and then the cross-cutting knife 332 of the cross-cutting assembly 33 cuts the film-coating sheet 2 at a predetermined position.

[0056] like Figure 7 As shown, the second material discharging mechanism 20 includes a material discharging plate 21, a material discharging roller 22 rotatably connected to the material discharging plate 21, and a plurality of support rollers 23 rotatably connected to the material discharging plate 21. The material discharging roller 22 is drivingly connected to a material discharging power member 24 provided. It also includes a material spreading assembly 25 provided at the material discharging end of the support roller 23. The material spreading assembly 25 includes a material spreading frame 251, a material spreading power member 252 fixed to the material spreading frame 251, and a material spreading roller 253 fixed to the power output end of the material spreading power member 252. The material spreading power member 252 is a cylinder.

[0057] In the production of the battery cell 1, it is often necessary to mark the surface of the battery cell 1, so when the battery cell 1 is coated, a film 3 with a mark is wrapped on the outside of the battery cell 1 together with the coating sheet 2. After the coating sheet 2 is cut, a certain distance is predetermined between the two parts of the coating sheet 2, and then the film 3 is pasted on the cut part of the coating sheet 2, and the two cut parts of the coating sheet 2 are connected by the film 3. When the cut part of the coating sheet 2 is wrapped on the outside of the battery cell 1, the film 3 is cut again, and a part of the film 3 is wrapped on the outside of the battery cell 1 along with the coating sheet 2, and the other part remains on the coating sheet 2 waiting to be coated with the next battery cell 1.

[0058] In other embodiments, in specific production, the feeding device is further provided with a film coating device. The film coating device is provided at the discharge end of the feeding device.

[0060] The enveloping mechanism 40 further includes a pressing roller 44 disposed above the roller 42. The pressing roller 44 is fixed to the power output end of a pressing power member 45 (cylinder). The pressing power member 45 drives the pressing roller 44 to move toward the roller 42 to better contact the workpiece with the roller.

[0061] Specifically, a connecting plate 46 is provided at the power output end of the pressing power member 45. The connecting plate 46 extends above the roller 42, and an elastic seat 47 is provided at the extending end. The pressing roller 44 is rotatably connected to the elastic seat 47, and an elastic member 48 is provided between the elastic seat 47 and the connecting plate 46, so that the distance between the pressing roller 44 and the roller 42 arranged in an arc shape can be changed.

[0062] More specifically, a slide bar is provided on the extension of the elastic seat 47 and the connecting plate 46 to slide together, and a spring is provided on the upper end of the slide bar. One end of the spring is abutted against the top of the slide bar, and the other end is abutted against the upper end of the elastic seat. Such an arrangement enables the workpiece placed on the arc-shaped roller 43 to not only be in full contact with the roller 43, but also to press the film sheet 2 tightly against the workpiece during film coating without leaving any bubbles.

[0063] Preferably, the connecting plate 46 is slidably connected to the rotating frame 41. The rotating power member 43 is a motor, and is connected to the roller 42 through a synchronous belt. There are two rotating frames 41, and they are symmetrically arranged; the rollers 42 of the two rotating frames 41 are connected through a rotating shaft 49. The two rotating frames 41 are arranged in a U shape, and the connecting plate 46 is also arranged in a U shape, and the bottom end is fixed to the power output end of the pressing power member 45.

[0064] Among them, Fig.10 — Fig.11 As shown, it also includes a conveying mechanism 50 fixed to the base 10. The conveying mechanism 50 is arranged between the two rotating frames 41 provided in the enclosing mechanism 40. The conveying mechanism 50 includes a conveying frame 51 fixed to the base 10, a groove-shaped fixed bracket 52 fixed to the conveying frame 51, and a groove-shaped movable bracket 53 fixed to the inner side of the fixed bracket 52.

[0065] The discharging assembly 612 is arranged on one side of the conveying mechanism 50 .

[0066] The mounting frame 6141 is fixed on the base 10 and spans the conveying mechanism 50 and the cutting mechanism 30. Specifically, the suction block 6144 is arranged between the first pressing assembly 31 and the second pressing assembly 32, that is, above the pad 315 and the second pressing plate 323. When the cross-cutting knife 332 of the cross-cutting assembly 33 cuts the film sheet 2, the movable pressing frame 321 moves under the action of the adjusting power member 324 and drives the cut film sheet 2 to a predetermined distance, and then the suction block 6144 adheres the sucked film 3 to the film sheet 2.

[0067] Specifically, the lifting power member 54 is arranged at the bottom end of the fixed bracket 52, and a support plate 56 is provided at the power output end of the lifting power member 54. The support plate 56 is provided with a slide rail so that the slider provided at the bottom end of the movable bracket 53 is slidably connected to the slide rail. The horizontal power member 55 is fixed on the support plate 56, and its power output end is fixedly connected to the movable bracket 53. Under the drive of the horizontal power member 55, the movable bracket 53 is slidably connected relative to the support plate 56. The movable bracket 53 is arranged parallel to the inner side of the fixed bracket 52, and the grooves of the two overlap.

[0068] The fixed bracket 52 and the movable bracket 53 are arranged between the two rotating frames 41 of the enclosing mechanism 40, and the arc-shaped roller 42 is slightly higher than the fixed bracket 52 and the movable bracket 53. When the movable bracket 53 is lifted by the lifting power member 54, the workpiece is just above the roller 42, and when the movable bracket 53 is lowered, the workpiece is just hung on the arc-shaped roller 42. At the same time, the fixed bracket 52 and the movable bracket 53 also pass through the movable pressing frame 321 and the fixed pressing frame 311, and are arranged below the first pressing plate 313 and the second pressing plate 323.

[0069] The working process of the conveying mechanism 50 is as follows: the lifting mechanism 54 drives the horizontal power member 55 and the movable bracket 53 to rise. Since the groove of the movable bracket 53 is provided at the same position as the groove of the fixed bracket 52, when the movable bracket 53 rises, it drives the workpiece on the fixed bracket 52 to rise. Then, the movable bracket 53 moves forward relative to the fixed bracket 52 under the action of the horizontal power member 55, and the moving distance is the distance between two adjacent grooves (if necessary, the moving distance is several times the distance between two adjacent grooves). After moving to the set position, the movable bracket 53 descends and the two ends of the workpiece are hung on the rollers 42 of the two rotating frames 41, so that the workpiece obtains the rotational power under the drive of the rollers 42. The remaining workpieces move with the movable bracket 53 for the set distance and are hung in the corresponding grooves of the fixed bracket 52 respectively. After the movable bracket 53 descends, it is reset under the action of the horizontal power member 55.

[0070] A coating method, such as Fig.12 As shown, the movable bracket 53 of the conveying mechanism 50 lifts the workpiece under the action of the lifting power member 54, and the movable bracket 53 moves forward several slots relative to the fixed bracket 52 under the action of the horizontal power member 55 to move the workpiece of the fixed bracket 52 forward; the movable bracket 53 descends, and the workpiece above the encapsulating mechanism 40 falls on the arc-shaped roller 42, and the roller 42 drives the workpiece to rotate; the groove of the movable bracket 53 is lower than the groove of the fixed bracket 52, the workpiece of the movable bracket 53 falls on the fixed bracket 52, and the movable bracket 53 is reset; the film sheet 2 is released from the discharge mechanism 20, and the film sheet 2 of the set length is cut off by the cutting mechanism 30; the second pressing plate 323 of the cutting mechanism 30 sends the film sheet 2 to the upper side of the rotating workpiece; the rotating workpiece drives the film sheet 2 to wrap around the outside of the workpiece, and the pressing roller 44 presses the film sheet 2; after the filming is completed, the movable bracket 53 will be removed to wait for the next workpiece.

[0071] Specifically, the discharge roller 22 of the second discharge mechanism 62 transfers the film sheet 2 to the cutting mechanism 30, and then the first pressing assembly 31 and the second pressing assembly 32 fix the film sheet 2, the cross-cutting power member 331 drives the cross-cutting knife 332 to cut the film sheet 2, and the movable pressing frame 321 moves under the action of the adjusting power member 324 and drives the cut film sheet 2 to a predetermined distance. At the same time, the first discharge mechanism 61 discharges the film 3 under the action of the discharge assembly 612, and the cutting assembly 613 cuts the film 3 of a predetermined length. The cut film 3 is sucked by the suction block 6144, and then the suction block 6144 adheres the sucked film 3 to the cut portion of the cut film sheet 2, connecting the cut two parts of the film sheet 2 together. One end of the film sheet 2 contacts the rotating battery cell 1 on the encapsulation mechanism, and the rotating battery cell 1 wraps the film sheet 2 around its outside. When the film sheet 2 passes the cutting position, the cutting knife 344 of the cutting assembly 34 moves downward to cut the film 3, and the battery cell 1 continues to rotate to wrap the remaining film sheet 2 and film 3 on its outside, thereby completing the wrapping of the film sheet 2 and film 3 on the outside of the battery cell 1.

[0072] The present invention is mostly used in the production of battery cells, wherein the workpiece is the battery cell. Under the operation of the present invention, the circular battery cell is wrapped with a film on the periphery, which is beneficial to the subsequent production of the battery cell, and also replaces the manual film coating, reduces labor costs, improves productivity, and at the same time, improves the accuracy of the film coating and reduces production accidents.

[0073] In summary, the present invention provides a double feeding device, in which a feeding mechanism feeds the film, and a first feeding mechanism feeds the film, and the two meet at a cutting mechanism, and the film is attached to the film. The double feeding device can feed materials at the same time, and wrap the film on the inner side of the film sheet, so that the mark is not easily worn. The present invention simplifies the process of shaping the film of the workpiece, and upgrades the film from manual to automated; the automated equipment has high manual positioning accuracy, high consistency, and high operating accuracy, which effectively improves production capacity, reduces labor costs, and improves production safety.
