Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and in particular to a coating film body processing device. Background Art

[0002] The square shell battery cell needs 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, wherein the large surface a1 corresponds to the large surface of the battery cell, the side surface a2 corresponds to the side surface of the battery cell, and the bottom surface a3 corresponds to the bottom surface of the battery cell. When in use, the bottom support plate b is arranged on the bottom surface a3 to strengthen the structural strength of the bottom surface a3. The existing insulating film a and the bottom support plate b have low assembly efficiency and are difficult to meet the needs. Summary of the invention

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

[0004] The embodiments of the present invention are implemented by the following technical solutions:

[0005] A coating film body processing equipment 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 and connected by the hot melt mechanism. Specifically, the hot melt mechanism moves to the third transfer mechanism to cooperate with the second transfer mechanism and the third transfer mechanism 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 transfer mechanism and the third transfer mechanism return after taking the material from the silo, and the next round of hot-melt processing of the coating film body is carried out when the hot melt mechanism returns to the third transfer mechanism. This reciprocating cycle can greatly improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] 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.

[0024] 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.

[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 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.

[0026] Please refer to Figures 1 to 15 , a coating film body 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 support plate b to the hot melt mechanism 5; the insulating film a and the bottom support plate b are hot-melted in the hot melt mechanism 5 to form a coating film body; the first transfer mechanism 2 is used to transfer the coating film body from the hot melt mechanism 5 to other stations, which can be a temporary storage station or directly cooperate with other mechanisms to put into the coating work of the single battery cell (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 hot-melt connected with the bottom support plate b by 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 return after taking the material at the silo 1, and when the hot-melt mechanism 5 returns to the third transfer mechanism 4, the next round of hot-melt processing of the coating film body is carried out. Such a reciprocating cycle can greatly improve the production efficiency.

[0027] like Figure 3 and Figure 4 As shown, the second transport 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, and a second driving member 34 is provided on the main adsorption plate 31, and 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, a single sheet of the insulating film a can be grabbed from the silo 1. Specifically, during use, the main adsorption plate 31 and the auxiliary adsorption plate 32 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 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 insulating film a adjacent to it can be broken, so that the precise grabbing of a single insulating film a can be achieved.

[0028] In some embodiments, a first negative pressure hole may be provided on both the main adsorption plate 31 and the auxiliary adsorption plate 32, 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 30 may also be provided on the main adsorption plate 31 and the auxiliary adsorption plate 32, and the first suction cup 30 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 by 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 away from the insulating film a during operation.

[0030] like Figure 1 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. 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 board 35 and a mold removal plate 37. The main adsorption plate 31 is fixedly assembled to the integrated board 35. The integrated board 35 is adjustably arranged relative to the hot melt mechanism 5. The mold removal plate 37 is located between the two main adsorption plates 31, and the mold removal 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 board 35 through a connecting column 38. A third driving member 362 is arranged on the integrated board 35. Preferably, the third driving member 362 is a cylinder, which is fixedly mounted on the integrated board 35, and the mold removal plate 37 is mounted on the telescopic end of the third driving member 362 and is driven by the third driving member 362. When in 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 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, a first support beam 011 is provided on the frame, and the second transfer mechanism 3 and the third transfer mechanism 4 are both installed on the first support beam 011 through a linear module, so that the second transfer mechanism 3 and the third transfer mechanism 4 can move 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 arranged adjacent to the silo 1. This arrangement facilitates the rapid hot melting of the insulating film a and the bottom support plate b at the hot melt mechanism 5 to form a coating film body.

[0033] In this embodiment, the second transfer mechanism 3 further includes a first linear module 36, and the third driving member 362 is installed on the first linear module 36 through the adapter plate 361, and is driven by the first linear module 36 so that the third driving member 362, i.e., the integrated plate 35, can move in the longitudinal direction Z. The first linear module 36 is driven by the linear module installed on the first support beam 011 so that it moves 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 to approach or move away from the insulating film a on the main adsorption plate 31. When in 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 to correspond to the bottom surface portion a3 through the hot melt pressure plate 41, and presses the bottom support plate b to fit tightly to the bottom surface portion 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 together to form a coating film body. Subsequently, 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, and the second suction cup 411 is externally connected to a negative pressure generator to generate negative pressure to grab 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 in the second direction Y. A transfer profile 43 is mounted on the second linear module 42, and the transfer profile 43 is driven by the second linear module 42 to move in the longitudinal direction Z. An extension plate 44 is arranged on the transfer profile 43, and the extension plate 44 is extended along the second direction Y. A fourth driving member 45 is arranged on the extension plate 44. The hot melt pressure plate 41 is installed on the extension plate 44 through the fourth driving member 45, and is driven by the fourth driving member 45 to move in 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 between the two.

[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 6 As 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 surface a3 or the bottom support plate b, which is used to heat the bottom support plate b and the insulating film a to connect the two together by hot melting.

[0040] The hot melt platform 52 is provided with a third suction cup 521, and the third suction cup 521 is used for adsorbing and fixing the insulating film a.

[0041] like Figures 7 to 12 As shown, the silo 1 includes a first silo 11, a second silo 12, a first lifting part 13 and a second lifting part 14, wherein: a plurality of insulating films a are stacked on the first silo 11, and a plurality of bottom supporting plates b are stacked on the second silo 12; the first lifting part 13 is arranged corresponding to the first silo 11, and the first lifting part 13 is used to lift the insulating film a close to the second transfer mechanism 3, and the second lifting part 14 is arranged corresponding to the second silo 12, and the second lifting part 14 is used to lift the bottom supporting plate b close to the third transfer mechanism 4. In this embodiment, the silo 1 and the lifting part are both installed on the frame.

[0042] like Fig.10 As shown, the first warehouse part 11 includes a first bottom plate 110, a first lifting plate 111 is stacked on the first bottom plate 110, a plurality of first blocking columns 1101 are arranged around the first bottom plate 110, the first lifting plate 111 is in the area defined by the plurality of first blocking columns 1101, a plurality of insulating films a are stacked on the first lifting plate 111, and the first lifting part 13 acts on the first lifting plate 111, so that the first lifting plate 111 and the insulating film a move synchronously to approach the second transfer mechanism 3. In this embodiment, there are four first blocking columns 1101, which are arranged in a ring around the first lifting plate 111 and are used to limit the insulating film a on the first lifting plate 111.

[0043] Furthermore, the first bottom plate 110 is provided with a positioning pin 112 extending upward in the longitudinal direction Z, and the positioning pin 112 penetrates the first lifting plate 111 and penetrates a plurality of insulating films a on the first lifting plate 111. The positioning pin 112 here is used to further limit the insulating films a to ensure that the insulating films a on the first lifting plate 111 are neatly stacked, so as to facilitate the second transfer mechanism 3 to grab them.

[0044] In this embodiment, a first stopper 11011 is provided on the first stopper column 1101, and 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 here can break the vacuum of the insulating film a adjacent to the uppermost insulating film a when the uppermost insulating film a is captured and separated from the first chamber 11, so as to ensure that the number of insulating films a captured at a single time is only one, and 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.

[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. Fig.10 As shown, optionally, the first damping member 11012 is a spring. The first damping member 11012 is pressed between the first stopper 11011 and the first stopper column, and the first stopper 11011 is slidably connected to the first stopper column through a slide rail slider assembly. The first damping member 11012 here can achieve buffering when the first lifting plate 111 hits the first stopper 11011 to avoid hard contact.

[0046] The first bottom plate 110 is provided with a second stopper 1102, and the second stopper 1102 is provided with a brush 11021, and 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 here can further prevent the lower insulating film a from adhering to the upper insulating film and following the upper insulating film a from detaching from the first bin 11 during the process of the upper insulating film a being grabbed and detached from the first bin 11, specifically, when the lower insulating film a passes through the brush 11021, it is blocked by the brush 11021 and falls back to the first bin 11.

[0047] like Fig.10 and Fig.11 As shown, the first lifting part 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 bottom plate 110 is disposed on the frame and is located above the first lifting part 13. Fig.11As shown, a driving column 1111 is provided on the first lifting plate 111, and the driving column 1111 penetrates the first bottom plate 110 and extends downward in the longitudinal direction Z. A plurality of driving columns 1111 are arranged in 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 arranged on the first push plate 134, and the first guide rod 133 penetrates the first mounting plate 131 and is slidably connected thereto. The first guide rod 133 is extended along the longitudinal direction Z. When in use, the first driving mechanism 132 drives the first push plate 134 to move upward in the longitudinal direction Z. During this process, the first driving head 135 approaches the driving column 1111 in the longitudinal direction Z upward until the first clamping portion 136 is clamped to the second clamping portion 11111, and then the first driving mechanism 132 continues to act to realize the continuous upward movement of the first lifting plate 111 in 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. Such an arrangement can ensure the structural stability of the first lifting plate 111 when it moves along the longitudinal direction Z.

[0049] like Fig.12 As shown, the second warehouse part 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. 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. The second lifting part 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 part 14. The second bottom plate 120 is penetrated with a driving hole 1201. The second lifting part 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 column 122 through a slide rail slider assembly, and the limit plate 123 at least partially extends into the guide groove 1221 and is located on the upward movement path of the second lifting plate 121 along the longitudinal direction Z. A second damping member 124 is provided between the limit plate 123 and the guide column 122 to provide a damping force for the limit plate 123 when it approaches the third transfer mechanism 4 along the longitudinal direction Z. The limit plate 123 here is used to prevent the second lifting plate 121 from disengaging from the guide groove 1221 along the longitudinal direction Z, and to provide a buffering force for the second lifting plate 121 through the second damping member 124 when the second lifting plate 121 abuts against the limit plate 123, so as to prevent the second lifting plate 121 from hard contact with the limit plate 123. Preferably, the second damping member 124 is a spring.

[0051] like Fig.12 As shown, the second lifting part 14 includes a second mounting plate 140, a second driving mechanism 141 and a second push plate 143, wherein: the second mounting plate 140 is assembled on the frame, the second push plate 143 is slidably mounted on 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 approach or move away from the second lifting plate 121 along the longitudinal direction Z. The second driving mechanism 141 is a screw stepping motor.

[0052] like Figure 8 and Fig. 9 As shown, the silo 1 also includes a guide plate 15 and a drawer plate 16, the first lifting portion 13 and the second lifting portion 14 are located below the drawer plate 16, the first bin portion 11 and the second bin portion 12 are mounted on the drawer plate 16, and the drawer plate 16 is slidably connected to the guide plate 15. Specifically, the drawer plate 16 is slidably connected to the guide plate 15 through a slide rail slider assembly. In this embodiment, the first bottom plate 110 and the second bottom plate 120 are both mounted on the frame through the sliding connection structure of the drawer plate 16 and the guide plate 15, and the guide plate 15 is mounted on the frame. The drawer plate 16 can move along the first direction X relative to the guide plate 15. In this way, it is convenient for the staff to pull out the first bin portion 11 and the second bin portion 12 to supplement the insulating film a and the bottom support plate b during operation.

[0053] Optionally, there may be two or more drawer panels 16 , and two adjacent drawer panels 16 are also slidably connected via a slide rail and slider assembly to increase the pulling stroke of the first compartment 11 and the second compartment 12 in the first direction X.

[0054] In this embodiment, the first bin 11 and the second bin 12 are both mounted on the bearing plate 17, and the sliding connection structures of the drawer plate 16 and the guide rail plate 15 are two arranged at intervals, and the bearing plate 17 spans between the sliding connection structures of the two drawer plates 16 and the guide rail plate 15. It should be noted that a hole structure is configured on the bearing plate 17, so that the first lifting part 13 and the second lifting part 14 can pass through the bearing plate 17 to reach the first bin 11 and the second bin 12 respectively during operation.

[0055] like Figure 3 , Figures 13 to 15As shown, the first transport mechanism 2 includes a fixed plate 23 and a first driving 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.
