[0043] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0044] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0046] Please refer to Figures 1 to 34, a battery cell coating equipment, including a flipping mechanism 1, a reflow line 2, a feeding mechanism 31, a first transfer mechanism 32, a silo 4, a fourth transfer mechanism 5, a packaging mechanism and a gluing mechanism 02, wherein the flipping mechanism 1, the reflow line 2, the feeding mechanism 31, the first transfer mechanism 32, the silo 4, the fourth transfer mechanism 5, the packaging mechanism and the gluing mechanism 02 are all installed on a frame 01; the feeding mechanism 31 is used to transfer the battery cell to the flipping mechanism 1; the first transfer mechanism 32 is used to transfer the battery cell flipped at the flipping mechanism 1 to the reflow line 2; the silo 4 is used to accommodate the coating film body; the fourth transfer mechanism 5 is used to transfer the coating film body to the first packaging point of the reflow line 2, and coat the coating film body to the large surface c1 of the battery cell and the bottom surface c3 of the battery cell; the packaging mechanism is arranged near the first packaging point, and is used to coat and fix the coating film body to the single battery cell c; the gluing mechanism 02 is arranged along the reflow line 2 and is located at the downstream side of the packaging mechanism. In this embodiment, Figure 4 Shown and Figure 5 As shown, the single cell c to be coated is placed horizontally, and in order to facilitate the coating of the single cell c, the cell coating equipment needs to flip the single cell c during use, that is, when in the coating state, the bottom surface a3 of the single cell c is set upward along the longitudinal direction Z, and this action is achieved by the flipping mechanism 1. Then, the single cell c is automatically coated on the return line 2 through the packaging mechanism and then unloaded. The cooperation of various mechanisms here can realize the automatic coating of the single cell c, which is conducive to improving the coating efficiency of the cell.

[0047] like Figure 1 , Figures 5 to 7 As shown, the flip mechanism 1 includes a fixed transfer plate 10 and a movable transfer plate 11. The fixed transfer plate 10 is fixedly arranged relative to the return line 2. The movable transfer plate 11 is adjustably mounted on the fixed transfer plate 10. The movable transfer plate 11 can move relative to the fixed transfer plate 10 along a first direction X. A flip assembly 13 and a first driving member 12 are rotatably mounted on the fixed transfer plate 10. The first driving member 12 is used to drive the flip assembly 13 to rotate. The single cell c is fixed to the flip assembly 13. Specifically, as Figure 5 As shown, the movable transport plate 11 is slidably connected to the fixed transport plate 10 via a slide rail and slider assembly, and a cylinder is disposed on the fixed transport plate 10 for driving the movable transport plate 11 to move relative to the fixed transport plate 10.

[0048] like Figures 5 to 7As shown, the flip assembly 13 includes a flip seat 131 rotatably mounted on the transfer movable plate 11, and the flip seat 131 is provided with a first reference block 132 and a second reference block 134, as well as a first positioning block 133 and a second positioning block 135; the first positioning block 133 is arranged opposite to the first reference block 132, and the first positioning block 133 can approach or move away from the first reference block 132 along the first direction X, and the second positioning block 135 is arranged opposite to the second reference block 134, and the second positioning block 135 can approach or move away from the second reference block 134 along the second direction Y; the first direction X is perpendicular to the second direction Y, and the second direction Y is parallel to the rotation axis of the flip seat 131; the single cell c is in a space defined by the first reference block 132, the second reference block 134, the first positioning block 133 and the second positioning block 135. More specifically, two supports 14 are provided on the movable plate 11, and the two supports 14 are spaced apart in the second direction Y. The flip seat 131 is rotatably mounted on the support 14 via a bearing, that is, the flip seat 131 is rotatably mounted on the movable plate 11 via the support 14. The first driving member 12 is a motor, which is provided on one of the supports 14, and the output shaft of the motor is in transmission connection with the flip seat 131 to drive it to rotate. In this embodiment, the first driving member 12 drives the flip seat 131 to rotate ninety degrees so that the bottom surface c3 of the battery cell is arranged upward along the longitudinal direction Z.

[0049] Furthermore, a bearing bar 136 is provided on the flip seat 131, and the bearing bar 136 is extended along the first direction X, the first reference block 132 is located at one end of the bearing bar 136, and the first positioning block 133 is located at the other end of the bearing bar 136. Correspondingly, the second positioning block 135 is located on one side of the bearing bar 136 in the second direction Y, and the second reference block 134 is located on the other side of the bearing bar 136 in the second direction Y. When in use, the single cell c is placed on the bearing bar 136, and a supporting force is provided for the single cell c in the longitudinal direction Z before the single cell c is flipped. That is, after the single cell c is transferred to the flip mechanism 1 by the feeding mechanism 31, it is first placed on the bearing bar 136, and finally the positioning block and the reference block cooperate to position and fix the single cell c.

[0050] Specifically, Figure 6 and Figure 7 As shown, the first positioning block 133 and the second positioning block 135 are driven by a cylinder installed on the flip seat 131. The first reference block 132 is fixedly installed on the bearing bar 136, and the second reference block 134 is fixedly installed on the flip seat 131. Optionally, the bearing bar 136 and the positioning blocks and the reference blocks are two groups, and are arranged at intervals along the second direction Y. In this way, two single cells c can be processed at a time, which is conducive to improving efficiency.

[0051] The second reference block 134 and / or the second positioning block 135 are provided with positioning grooves, and the single cell c is clamped in the positioning grooves. The positioning grooves are used to fix the single cell c to prevent the single cell c from being separated from the supporting bar 136, i.e., the turning mechanism 1, during the turning process.

[0052] In some embodiments, Figure 8 As shown, the first reference block 132 is adjustably arranged on the flip seat 131, and the first reference block 132 can move along the second direction Y. Specifically, the first reference block 132 is slidably connected to the flip seat 131 through a slide rail slider assembly, and the first reference block 132 is driven by a cylinder to move along the second direction Y. It should be noted that, in this embodiment, the bottom surface c3 of the battery cell is attached to the first reference block 132. With such a configuration, when the single battery cell c is flipped to the point where the bottom surface c3 of the battery cell is facing upward along the longitudinal direction Z, the first reference block 132 can be detached from the bottom surface c3 of the battery cell by moving along the second direction Y, thereby creating a space adjustment member for the first transfer mechanism 32 to grab the single battery cell c. It is also worth noting that, in this embodiment, the movable transfer plate 11 is driven by a linear module to move relative to the fixed transfer plate 10.

[0053] like Fig. 9 As shown, in this embodiment, the film coating equipment further includes a hot melt mechanism 8, a second transfer mechanism 6 and a third transfer mechanism 7. The second transfer mechanism 6 is used to transfer the insulating film a to the hot melt mechanism 8, and the third transfer mechanism 7 is used to transfer the bottom plate b to the hot melt mechanism 8; the insulating film a and the bottom plate b are hot-melted in the hot melt mechanism 8 to form a coating film body; the fourth transfer mechanism 5 is used to transfer the coating film body from the hot melt mechanism 8 to the first packaging point of the reflow line 2. The battery cell film coating equipment here can hot-melt the insulating film a and the bottom plate b to form a coating film body, and can effectively improve the production efficiency by coordinating the production rhythm of the reflow line 2 and other mechanisms.

[0054] like Fig. 9 and Fig.10 As shown, the second transport mechanism 6 includes a main adsorption plate 61 and an auxiliary adsorption plate 62, the main adsorption plate 61 and the auxiliary adsorption plate 62 are used to grab the insulating film a, the main adsorption plate 61 is rotatably connected to the auxiliary adsorption plate 62, and a second driving member 64 is provided on the main adsorption plate 61, and the second driving member 64 is used to drive the auxiliary adsorption plate 62 to rotate relative to the main adsorption plate 61. By rotatably connecting the main adsorption plate 61 with the auxiliary adsorption plate 62, a single sheet of the insulating film a can be grabbed from the silo 4. Specifically, during use, the main adsorption plate 61 and the auxiliary adsorption plate 62 are first parallel to each other. After grabbing the insulating film a, in the process of lifting it upward along the longitudinal direction Z, the auxiliary adsorption plate 62 is driven to rotate relative to the main adsorption plate 61 by the second driving member 64, so that the vacuum adsorption force between the grabbed insulating film a and the adjacent insulating film a can be broken, thereby achieving a single accurate grabbing of a single insulating film a.

[0055] In some embodiments, a first negative pressure hole may be provided on the main adsorption plate 61 and the auxiliary adsorption plate 62, and the first negative pressure hole may be externally connected to a negative pressure generator to generate negative pressure. In other embodiments, a first suction cup 60 may also be provided on the main adsorption plate 61 and the auxiliary adsorption plate 62, and the first suction cup 60 may be externally connected to a negative pressure generator to generate negative pressure.

[0056] In this embodiment, the main adsorption plate 61 and the auxiliary adsorption plate 62 are rotatably connected by a hinge 63. The second driving member 64 is preferably a cylinder, one end of which is hinged to the main adsorption plate 61 and the other end is hinged to the auxiliary adsorption plate 62. The second driving member 64 is located on the back side of the main adsorption plate 61 and the auxiliary adsorption plate 62. The back side of the main adsorption plate 61 and the auxiliary adsorption plate 62 is the side away from the insulating film a during operation.

[0057] like Figure 3a As shown, the insulating film a includes two large face portions a1, and the two large face portions a1 are symmetrically arranged about the bottom face portion a3. Based on this, in this embodiment, as shown in FIG. Fig.10 As shown, there are two main adsorption plates 61. The two main adsorption plates 61 are used to correspond to the two large surface areas a1.

[0058] Furthermore, the second transfer mechanism 6 also includes an integrated plate 65 and a mold removal plate 67. The main adsorption plate 61 is fixedly assembled to the integrated plate 65, and the integrated plate 65 is adjustably arranged relative to the hot melt mechanism 8; the mold removal plate 67 is located between the two main adsorption plates 61, and the mold removal plate 67 can abut against or detach from the insulating film a. In this embodiment, the main adsorption plate 61 is fixedly assembled to the integrated plate 65 through a connecting column 68, and a third driving member 662 is arranged on the integrated plate 65. Preferably, the third driving member 662 is a cylinder, which is fixedly mounted on the integrated plate 65, and the mold removal plate 67 is mounted on the telescopic end of the third driving member 662 and is driven by the third driving member 662. When in use, when the second transfer mechanism 6 grabs the insulating film a to the hot melt mechanism 8, the third driving member 662 acts on the mold removal plate 67 to press the insulating film a to the hot melt mechanism 8 to ensure that the insulating film a is smoothly detached from the first suction cup 60.

[0059] like Figure 1 , Fig. 9 and Fig.10 As shown, a first support beam 011 is provided on the frame 01, and the second transfer mechanism 6 and the third transfer mechanism 7 are both installed on the first support beam 011 through a linear module, so that the second transfer mechanism 6 and the third transfer mechanism 7 can move in the second direction Y. In this embodiment, the silo 4 is located on one side of the first support beam 011 along the first direction X, and the hot melt mechanism 8 is arranged adjacent to the silo 4. This arrangement facilitates the rapid hot melting of the insulating film a and the bottom support plate b at the hot melt mechanism 8 to form a coating film body.

[0060] In this embodiment, the second transfer mechanism 6 further includes a first linear module 66, and the third driving member 662 is installed on the first linear module 66 through an adapter plate 661, and is driven by the first linear module 66 so that the third driving member 662, i.e., the integrated plate 65, can move along the longitudinal direction Z. The first linear module 66 is driven by the linear module installed on the first support beam 011 so that it moves along the second direction Y.

[0061] The third transfer mechanism 7 includes a hot melt press plate 71, which is used to transfer the bottom support plate b to the hot melt mechanism 8. The hot melt press plate 71 can extend to the area between the two main adsorption plates 61 and drive the bottom support plate b to approach or move away from the insulating film a on the main adsorption plate 61. When in use, the second transfer mechanism 6 cooperates with the third transfer mechanism 7, specifically, the second transfer mechanism 6 fixes the insulating film a to the hot melt mechanism 8, and the third transfer mechanism 7 transfers the bottom support plate b to between the two main adsorption plates 61 to correspond to the bottom surface portion a3 through the hot melt pressure plate 71, and presses the bottom support plate b to fit tightly to the bottom surface portion a3. At this time, the hot melt mechanism 8 acts on the insulating film a and the bottom support plate b to hot-melt the two together to form a coating film body. Subsequently, the hot melt pressure plate 71 is separated from the bottom support plate b, and the molding plate 67 is taken to press the bottom support plate b of the coating film body. The first suction cup 60 is separated from the insulating film a that is separated from the coating film body along the longitudinal Z upward direction, and finally the molding plate 67 is taken to separate from the coating film body along the longitudinal Z upward direction.

[0062] In this embodiment, a second suction cup 711 is disposed on the hot melt pressing plate 71, and the second suction cup 711 is externally connected to a negative pressure generator to generate negative pressure to grab the bottom support plate b.

[0063] like Fig.11 As shown, the third transfer mechanism 7 also includes a second linear module 72, which is driven by a linear module arranged on the first support beam 011 to move along the second direction Y.

Specifically, through the structural design of the extension plate 74, the hot melt pressure plate 71 deviates from the main structure of the third transfer mechanism 7 in the second direction Y. In this way, the interference between the second transfer mechanism 6 and the third transfer mechanism 7 can be effectively avoided during the cooperation process between the two.

[0064] Optionally, the fourth driving member 75 is a cylinder, which cooperates with the second linear module 72 to quickly and accurately adjust the position of the hot melt pressing plate 71 in the longitudinal direction Z.

Then, the two clamps 2441 approach each other along the second direction Y to press the side portion a2 tightly to the side c2 of the battery cell. At this time, the short-side hot melt block 246 acts on the side c2 of the battery cell to hot-melt the side portion a2 to the side c2 of the battery cell. It should be noted that the two side film pressing mechanisms are symmetrically arranged about the clamp 21 to complete the pressing and fitting of a total of four side portions a2 of the side c2 of the two battery cells. It should be noted that during this process, the clamp 21 is in an unlocked state, and the single battery cell c is fixed by the auxiliary fixture 245.

In this embodiment, after the coating film body on the single cell c is processed by the long-side hot melt block 231 and the short-side hot melt block 246, it needs to be further fixed to improve its firmness. The single cell c is transported to the gluing mechanism 02 through the reflow line 2 following the fixture 21. First, the top segment 0241 is glued to the bottom surface c3 of the cell, that is, the bottom support plate b of the coating film body, through the top glue head 0214.
