Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a coating film processing device. Background Art

[0002] Square shell battery cells need to be covered with a layer of film mold outside the shell for insulation. The existing film mold is generally made of Figure 1 The insulating film a and Figure 2 The bottom support plate b shown in the figure is composed of a large surface a1, a side surface a2, and a bottom surface a3. The large surface a1 corresponds to the large surface of the battery cell, the side surface a2 corresponds to the side of the battery cell, and the bottom surface a3 corresponds to the bottom surface of the battery cell. During use, the bottom support plate b is placed on the bottom surface a3 to enhance the structural strength of the bottom surface a3. The existing insulation film a and bottom support plate b have low assembly efficiency and are difficult to meet the demand. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a coating film processing device with high working efficiency.

[0004] The embodiments of the present invention are achieved through the following technical solutions:

[0005] A coating film processing device includes: a silo for accommodating an insulating film and a bottom support plate; a second transfer mechanism for transferring the insulating film to a hot melt mechanism; a third transfer mechanism for transferring the bottom support plate to the hot melt mechanism; the insulating film and the bottom support plate are hot-melted in the hot melt mechanism to form the coating film body; a first transfer mechanism for transferring the coating film body, and the hot melt mechanism can reciprocate between the third transfer mechanism and the first transfer mechanism. Here, the insulating film and the bottom support plate are hot-melted together by the hot melt mechanism. Specifically, the hot melt mechanism moves to the third transfer mechanism to cooperate with the second and third transfer mechanisms to hot-melt the coating film body, and then moves to the first transfer mechanism to grab the processed coating film body for material. At this time, the second and third transfer mechanisms return after taking the material from the silo. When the hot melt mechanism returns to the third transfer mechanism, the next round of coating film hot-melt processing is carried out. This reciprocating cycle can greatly improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] Please refer to Figures 1 to 15 , a coating film processing equipment, including a silo 1, a second transfer mechanism 3, a third transfer mechanism 4, a first transfer mechanism 2 and a hot melt mechanism 5, wherein the silo 1, the second transfer mechanism 3, the third transfer mechanism 4, the first transfer mechanism 2 and the hot melt mechanism 5 are all installed on a frame (not shown in the figure). Figure 3 As shown, in this embodiment, the second transfer mechanism 3 is used to transfer the insulating film a to the hot melt mechanism 5, and the third transfer mechanism 4 is used to transfer the bottom plate b to the hot melt mechanism 5. The insulating film a and the bottom plate b are hot-melted in the hot melt mechanism 5 to form a coating film. The first transfer mechanism 2 is used to transfer the coating film from the hot melt mechanism 5 to another station, which can be a temporary storage station or directly cooperate with other mechanisms to be used for the coating of single battery cells (not shown in the figure). In this embodiment, the hot melt mechanism 5 can reciprocate between the third transfer mechanism 4 and the first transfer mechanism 2. Here, the insulating film a is connected to the bottom support plate b by hot-melt connection through the hot-melt mechanism 5. Specifically, the hot-melt mechanism 5 moves to the third transfer mechanism 4 to cooperate with the second transfer mechanism 3 and the third transfer mechanism 4 to hot-melt to form a coating film body, and then moves to the first transfer mechanism 2 to grab the processed coating film body by the first transfer mechanism 2 to unload the material. At this time, the second transfer mechanism 3 and the third transfer mechanism 4 take the material at the silo 1 and then return. When the hot-melt mechanism 5 returns to the third transfer mechanism 4, the next round of coating film hot-melt processing is carried out. This reciprocating cycle can greatly improve production efficiency.

[0027] like Figure 3 and Figure 4As shown, the second transfer mechanism 3 includes a main adsorption plate 31 and an auxiliary adsorption plate 32. The main adsorption plate 31 and the auxiliary adsorption plate 32 are used to grab the insulating film a. The main adsorption plate 31 is rotatably connected to the auxiliary adsorption plate 32. A second driving member 34 is provided on the main adsorption plate 31. The second driving member 34 is used to drive the auxiliary adsorption plate 32 to rotate relative to the main adsorption plate 31. By rotatably connecting the main adsorption plate 31 with the auxiliary adsorption plate 32, single grabbing in the process of grabbing the insulating film a from the silo 1 can be achieved. Specifically, during use, the main adsorption plate 31 and the auxiliary adsorption plate 32 are first made 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 32 is driven to rotate relative to the main adsorption plate 31 by the second driving member 34, so that the vacuum adsorption force between the grabbed insulating film a and the adjacent insulating film a can be broken, thereby achieving precise grabbing of a single insulating film a at a time.

[0028] In some embodiments, both the main adsorption plate 31 and the auxiliary adsorption plate 32 may be provided with a first negative pressure hole, which is externally connected to a negative pressure generator to generate negative pressure. In other embodiments, first suction cups 30 may also be provided on the main adsorption plate 31 and the auxiliary adsorption plate 32, which may be externally connected to a negative pressure generator to generate negative pressure.

[0029] In this embodiment, the main adsorption plate 31 and the auxiliary adsorption plate 32 are rotatably connected via a hinge 33. The second driving member 34 is preferably a cylinder, one end of which is hinged to the main adsorption plate 31 and the other end is hinged to the auxiliary adsorption plate 32. The second driving member 34 is located on the back side of the main adsorption plate 31 and the auxiliary adsorption plate 32. The back side of the main adsorption plate 31 and the auxiliary adsorption plate 32 is the side that faces away from the insulating film a during operation.

[0030] like Figure 1 As shown, the insulating film a includes two large portions a1, and the two large portions a1 are symmetrically arranged about the bottom portion a3. Based on this, in this embodiment, as shown in FIG. Figure 4 As shown, there are two main adsorption plates 31. The two main adsorption plates 31 are used to correspond to the two large surface areas a1.

[0031] Furthermore, the second transfer mechanism 3 also includes an integrated plate 35 and a mold removal pressure plate 37. The main adsorption plate 31 is fixedly assembled to the integrated plate 35, and the integrated plate 35 is adjustably arranged relative to the hot melt mechanism 5. The mold removal pressure plate 37 is located between the two main adsorption plates 31, and the mold removal pressure plate 37 can abut against or detach from the insulating film a. In this embodiment, the main adsorption plate 31 is fixedly assembled to the integrated plate 35 through a connecting column 38. A third driving member 362 is configured on the integrated plate 35. Preferably, the third driving member 362 is a cylinder, which is fixedly mounted on the integrated plate 35, and the mold removal pressure plate 37 is mounted on the telescopic end of the third driving member 362 and is driven by the third driving member 362. During use, when the second transfer mechanism 3 grabs the insulating film a to the hot melt mechanism 5, the third driving member 362 acts on the mold removal pressure plate 37 to press the insulating film a to the hot melt mechanism 5 to ensure that the insulating film a is smoothly detached from the first suction cup 30.

[0032] Figure 3 and Figure 4 As shown, the frame is provided with a first support beam 011. The second transfer mechanism 3 and the third transfer mechanism 4 are both mounted to the first support beam 011 via linear modules, enabling movement of the second transfer mechanism 3 and the third transfer mechanism 4 in the second direction Y. In this embodiment, the silo 1 is located on one side of the first support beam 011 along the first direction X, and the hot melt mechanism 5 is positioned adjacent to the silo 1. This arrangement facilitates rapid heat-melting of the insulating film a and the bottom support plate b at the hot melt mechanism 5 to form a coated film.

[0033] In this embodiment, the second transfer mechanism 3 further includes a first linear module 36. The third driving member 362 is mounted on the first linear module 36 via an adapter plate 361 and is driven by the first linear module 36 to enable the third driving member 362, i.e., the integrated plate 35, to move in the longitudinal direction Z. The first linear module 36 is driven by the linear module mounted on the first support beam 011 to move in the second direction Y.

[0034] The third transfer mechanism 4 includes a hot melt press plate 41, which is used to transfer the bottom support plate b to the hot melt mechanism 5. The hot melt press plate 41 can extend to the area between the two main adsorption plates 31 and drive the bottom support plate b close to or away from the insulating film a on the main adsorption plate 31. During use, the second transfer mechanism 3 cooperates with the third transfer mechanism 4, specifically, the second transfer mechanism 3 fixes the insulating film a to the hot melt mechanism 5, and the third transfer mechanism 4 transfers the bottom support plate b to between the two main adsorption plates 31 through the hot melt pressure plate 41 to correspond to the bottom surface a3, and presses the bottom support plate b to fit the bottom surface a3. At this time, the hot melt mechanism 5 acts on the insulating film a and the bottom support plate b to hot-melt the two into one to form a coating film body. Then the hot melt pressure plate 41 is separated from the bottom support plate b, and the molding plate 37 is taken to press the bottom support plate b of the coating film body. The first suction cup 30 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 37 is taken to separate from the coating film body along the longitudinal Z-upward direction.

[0035] In this embodiment, a second suction cup 411 is disposed on the hot melt pressing plate 41 . The second suction cup 411 is externally connected to a negative pressure generator for generating negative pressure to grasp the bottom support plate b.

[0036] like Figure 5 As shown, the third transfer mechanism 4 also includes a second linear module 42, which is driven by a linear module arranged on the first support beam 011 to move along the second direction Y. The second linear module 42 is equipped with a transition profile 43, which is driven by the second linear module 42 to move along the longitudinal direction Z. The transition profile 43 is provided with an extension plate 44, which is extended along the second direction Y. The extension plate 44 is provided with a fourth drive member 45. The hot melt pressure plate 41 is installed on the extension plate 44 through the fourth drive member 45 and is driven by the fourth drive member 45 to move along the longitudinal direction Z. The extension plate 44 here creates conditions for the hot melt pressure plate 41 to extend between the two main adsorption plates 31. Specifically, through the structural design of the extension plate 44, the hot melt pressure plate 41 deviates from the main structure of the third transfer mechanism 4 in the second direction Y. In this way, the interference between the second transfer mechanism 3 and the third transfer mechanism 4 can be effectively avoided during the cooperation process.

[0037] Optionally, the fourth driving member 45 is a cylinder, which cooperates with the second linear module 42 to quickly and accurately adjust the position of the hot melt pressing plate 41 in the longitudinal direction Z.

[0038] like Figure 6As shown, the hot melt mechanism 5 includes a hot melt platform 52 and a third linear module 51 arranged on the frame. The hot melt platform 52 is arranged on the third linear module 51 and is driven by the third linear module 51 to move along the second direction Y to adjust the spatial position of the hot melt platform 52 relative to the third transfer mechanism 4 and the first transfer mechanism 2 in the second direction Y, so as to facilitate the hot melt formation of the coating film body and the first transfer mechanism 2 to grab the coating film body from the hot melt mechanism 5.

[0039] The shape of the hot melt platform 52 is adapted to the shape of the coating film body. A hot fuse 522 is arranged on the hot melt platform 52 at a position corresponding to the bottom portion a3 or the bottom support plate b, which is used to heat the bottom support plate b and the insulating film a to hot-melt the two into one.

[0040] The hot melt platform 52 is provided with a third suction cup 521 , which is used to absorb and fix the insulating film a.

[0041] like Figures 7 to 12 As shown, the silo 1 includes a first silo portion 11, a second silo portion 12, a first lifting portion 13, and a second lifting portion 14. Several insulating films a are stacked on the first silo portion 11, and several bottom supporting plates b are stacked on the second silo portion 12. The first lifting portion 13 is disposed corresponding to the first silo portion 11 and is used to lift the insulating films a toward the second transfer mechanism 3. The second lifting portion 14 is disposed corresponding to the second silo portion 12 and is used to lift the bottom supporting plates b toward the third transfer mechanism 4. In this embodiment, the silo 1 and the lifting portion are both mounted on a frame.

[0042] like Figure 10 As shown, the first storage unit 11 includes a first base plate 110, on which a first lifting plate 111 is stacked. A plurality of first retaining posts 1101 are disposed around the perimeter of the first base plate 110. The first lifting plate 111 is located within the area defined by the plurality of first retaining posts 1101. Several insulating films a are stacked on the first lifting plate 111. The first lifting unit 13 acts on the first lifting plate 111, causing the first lifting plate 111 and the insulating films a to move synchronously toward the second transfer mechanism 3. In this embodiment, four first retaining posts 1101 are arranged in a ring around the first lifting plate 111 to limit the position of the insulating films a on the first lifting plate 111.

[0043] Furthermore, the first base plate 110 is provided with positioning pins 112 extending in the longitudinal direction Z. The positioning pins 112 penetrate the first lifting plate 111 and penetrate the plurality of insulating films a on the first lifting plate 111. The positioning pins 112 are used to further position the insulating films a, ensuring that the insulating films a on the first lifting plate 111 are neatly stacked and easily grasped by the second transfer mechanism 3.

[0044] In this embodiment, a first stopper 11011 is provided on the first stopper column 1101. The orthographic projection of the first stopper 11011 on the first lifting plate 111 is at least partially within the range of the insulating film a. The first stopper 11011 is capable of breaking the vacuum of the insulating film a adjacent to the topmost insulating film a during the process of the topmost insulating film a being removed from the first chamber 11, thereby ensuring that only a single insulating film a is captured at a time. More importantly, when the first lifting portion 13 acts on the first lifting plate 111 to move upward in the longitudinal direction Z, the first lifting plate 111 is limited in position.

[0045] Furthermore, the first stopper 11011 is slidably connected to the corresponding first stopper column 1101, and a first damping member 11012 is provided between the first stopper 11011 and the corresponding first stopper column 1101 to provide a damping force for the first stopper 11011 in the process of approaching the second transfer mechanism 3 along the longitudinal direction Z. Figure 10 As shown, first damping member 11012 is optionally a spring. First damping member 11012 is pressed between first stopper 11011 and the first stopper post. First stopper 11011 is slidably connected to the first stopper post via a slide rail and slider assembly. Here, first damping member 11012 can provide a buffer when first lifting plate 111 strikes first stopper 11011, preventing hard contact.

[0046] A second stopper 1102 is provided on the first base plate 110, and a brush 11021 is mounted on the second stopper 1102. The orthographic projection of the brush 11021 on the first lifting plate 111 is at least partially within the range of the insulating film a. The brush 11021 prevents the lower insulating film a from adhering to the upper insulating film and following it out of the first chamber 11 as the upper insulating film a is removed from the first chamber 11. Specifically, when the lower insulating film a passes by the brush 11021, it is blocked by the brush 11021 and falls back into the first chamber 11.

[0047] like Figure 10 and Figure 11 As shown, the first lifting portion 13 includes a first driving mechanism 132 and a first driving head 135. The first driving head 135 is provided with a first clamping portion 136. The first lifting plate 111 is provided with a second clamping portion 11111 that cooperates with the first clamping portion 136. The driving mechanism is used to drive the first driving head 135 so that the first clamping portion 136 abuts against or disengages from the second clamping portion 11111. In this embodiment, the first driving mechanism 132 is mounted on the frame through the first mounting plate 131, and a plurality of first driving heads 135 are integrated on the first push plate 134. Accordingly, the first base plate 110 is provided on the frame and is located above the first lifting portion 13. Figure 11As shown, a driving column 1111 is provided on the first lifting plate 111, and the driving column 1111 extends downward along the longitudinal direction Z through the first base plate 110. A plurality of driving columns 1111 are provided in a one-to-one correspondence with a plurality of first driving heads 135. Preferably, the first driving mechanism 132 is a screw stepping motor, and a first guide rod 133 is provided on the first push plate 134, and the first guide rod 133 extends through the first mounting plate 131 and is slidably connected thereto. The first guide rod 133 extends along the longitudinal direction Z. During use, the first driving mechanism 132 drives the first push plate 134 to move upward along the longitudinal direction Z. During this process, the first driving head 135 approaches the driving column 1111 upward along the longitudinal direction Z until the first clamping portion 136 is clamped to the second clamping portion 11111. Thereafter, the first driving mechanism 132 continues to function, so that the first lifting plate 111 continues to move upward along the longitudinal direction Z.

[0048] In this embodiment, the first clamping portion 136 is a convex structure, and the second clamping portion 11111 is a concave structure adapted to the shape of the first clamping portion 136. This arrangement can ensure the structural stability of the first lifting plate 111 when it moves along the longitudinal direction Z.

[0049] like Figure 12 As shown, the second bin portion 12 includes a second bottom plate 120 and a second lifting plate 121. The second bottom plate 120 is provided with a guide column 122, and the guide column 122 is provided with a guide groove 1221. The second lifting plate 121 is slidably embedded in the guide groove 1221. The bottom support plate b is stacked on the second lifting plate 121, and the second lifting portion 14 acts on the second lifting plate 121 so that it can slide along the guide groove 1221 to approach the third transfer mechanism 4. In this embodiment, the second bottom plate 120 is arranged on the frame and is above the second lifting portion 14. A driving hole 1201 is provided through the second bottom plate 120. The second lifting portion 14 acts on the second lifting plate 121 through the driving hole 1201. The guide groove 1221 here is used to guide the movement of the second lifting plate 121 along the longitudinal direction Z to ensure its structural stability.

[0050] Furthermore, a limit plate 123 is slidably mounted on the guide post 122 via a slide rail slider assembly. The limit plate 123 at least partially extends into the guide slot 1221 and is located on the upward motion path of the second lifting plate 121 along the longitudinal direction Z. A second damping member 124 is disposed between the limit plate 123 and the guide post 122 to provide a damping force to the limit plate 123 as it approaches the third transfer mechanism 4 along the longitudinal direction Z. The limit plate 123 is used to prevent the second lifting plate 121 from disengaging from the guide slot 1221 along the longitudinal direction Z. The second damping member 124 provides a buffering force to the second lifting plate 121 when the second lifting plate 121 abuts the limit plate 123, thereby preventing hard contact between the second lifting plate 121 and the limit plate 123. Preferably, the second damping member 124 is a spring.

[0051] As shown in Figure 12 , the second jacking part 14 comprises a second mounting plate 140, a second driving mechanism 141 and a second push plate 143, wherein the second mounting plate 140 is assembled to the rack, the second push plate 143 is slidingly mounted to the second mounting plate 140 through a second guide rod 142, and the second driving mechanism 141 is arranged on the second mounting plate 140 for driving the second push plate 143 to move along the longitudinal direction Z towards or away from the second jacking plate 121. The second driving mechanism 141 is a lead screw stepper motor.

[0052] As shown in Figure 8 and Figure 9 , the hopper 1 further comprises a guide rail plate 15 and a drawer plate 16, the first jacking part 13 and the second jacking part 14 are below the drawer plate 16, the first bin part 11 and the second bin part 12 are mounted to the drawer plate 16, and the drawer plate 16 is slidingly connected with the guide rail plate 15. Specifically, the drawer plate 16 is slidingly connected with the guide rail plate 15 through a slide rail sliding block assembly. In the embodiment, the first bottom plate 110 and the second bottom plate 120 are both mounted to the rack through the sliding connection structure of the drawer plate 16 and the guide rail plate 15, and the guide rail plate 15 is mounted to the rack. The drawer plate 16 can move along the first direction X relative to the guide rail plate 15. In this way, it is convenient for the worker to pull out the first bin part 11 and the second bin part 12 to replenish the insulation film a and the bottom support plate b during operation.

[0053] Optionally, the drawer plate 16 can be two or more, and adjacent two drawer plates 16 are also slidingly connected through a slide rail sliding block assembly to increase the pulling stroke of the first bin part 11 and the second bin part 12 along the first direction X.

[0054] In the embodiment, the first bin part 11 and the second bin part 12 are both assembled on a bearing plate 17, and the sliding connection structure of the drawer plate 16 and the guide rail plate 15 is two, which are arranged at intervals, and the bearing plate 17 spans between the two sliding connection structures of the drawer plate 16 and the guide rail plate 15. It should be noted that the bearing plate 17 is provided with a hole structure, which is used for the first jacking part 13 and the second jacking part 14 to pass through the bearing plate 17 to correspond to reach the first bin part 11 and the second bin part 12 during operation.

[0055] As shown in Figure 3 , Figures 13 to 15As shown, the first transport mechanism 2 includes a fixed plate 23 and a first drive member 24. A flip grabbing portion 25 is rotatably mounted on the fixed plate 23. The flip grabbing portion 25 is arranged corresponding to the large surface a1 of the insulating film a. The flip grabbing portion 25 is used to grab the insulating film a on the hot melt mechanism 5. The first drive member 24 is used to drive the flip grabbing portion 25 to flip so that the large surface a1 is attached to the large surface of the battery cell. The coating film processing equipment provided in this embodiment can be directly applied to the coating work of single battery cells. Specifically, the first transport mechanism 2 can transport the coating film body to the single battery cell so that the coating film body is at least partially attached to the single battery cell. Specifically, the bottom surface of the battery cell faces upward. Here, the first transport mechanism 2 grabs the coating film body so that the coating film body is above the bottom surface of the battery cell. At this time, the first drive member 24 drives the flip grabbing portion 25 so that the large surface a1 corresponds to the large surface of the battery cell.

[0056] Preferably, the first driving member 24 is a motor, which is mounted on the fixing plate 23 and is transmission-connected to the flipping and grabbing portion 25 .

[0057] In this embodiment, the flipping and grasping part 25 includes a negative pressure plate 251 rotatably mounted on the fixed plate 23, and the negative pressure plate 251 is provided with a second negative pressure hole for adsorbing the coating membrane body. Furthermore, a film pressing block 252 and a mounting frame 253 are provided on the negative pressure plate 251, and a plane rotary clamping cylinder 2531 is provided on the mounting frame 253. The plane rotary clamping cylinder 2531 corresponds to the four vertex corners of the coating membrane body and is used to grasp the four vertex corner areas of the coating membrane body. The plane rotary clamping cylinder 2531 clamping the coating mold body is an existing technology and will not be described in detail here. The film pressing block 252 here is used to press the coating mold body to the large surface of the battery cell during the process of the coating membrane body being attached to the large surface of the battery cell.

[0058] In another embodiment, the film pressing block 252 and the mounting frame 253 may also be equipped with a negative pressure structure to grasp and fix the film body by negative pressure adsorption. It should be noted that in this embodiment, the mounting frame 253 is no longer equipped with a flat rotary clamping cylinder 2531.

[0059] like Figure 14 and Figure 15 As shown, this embodiment includes two fixed plates 23 corresponding to two flip gripping sections 25. The two fixed plates 23 are fixedly mounted to a large plate 27. A buffer plate 26 is adjustably mounted on the large plate 27, with a first buffer spring interposed between the buffer plate 26 and the large plate 27. The buffer plate 26 is positioned between the two flip gripping sections 25 and corresponds to the bottom portion a3. During use, the buffer plate 26 is used to press the bottom portion a3, i.e., the bottom support plate b area of ​​the encapsulation mold, against the bottom surface of the battery cell, thereby preventing the first transfer mechanism 2 from making hard contact with the individual battery cells.

[0060] like Figure 3 and Figure 13 As shown, the first transfer mechanism 2 further includes a fourth linear module 21. The large plate 27 is mounted on the fourth linear module 21 via an extension frame 22 and is driven by the fourth linear module 21 to move in the longitudinal direction Z. A second support beam 012 is provided on the frame. The fourth linear module 21 is mounted on the second support beam 012 via a linear module and is driven by the linear module to move in the first direction X to approach or move away from a single battery cell or a blanking station.
