Description

Technical Field

[0001] The present application relates to the field of lithium battery production, and specifically to an end plate supply device. Background Art

[0002] End plates need to be mounted on both sides of the battery module, and an insulating cover needs to be mounted between the end plates and the battery module. Both sides of the insulating cover are adhesive surfaces. Generally, the insulating cover is first mounted on the end plate through one adhesive surface, and then the insulating cover and the end plate are simultaneously mounted on the battery module through the other adhesive surface.

[0003] In order to protect the stickiness of the adhesive surface of the insulation cover, a release film is applied to the adhesive surface of the insulation cover, and the release film needs to be torn off before mounting. The existing mounting method is to configure an upper surface film-tearing mechanism and a lower surface film-tearing mechanism at the same time. Before mounting the insulation cover to the end plate, the insulation cover is sent to the lower surface film-tearing mechanism, and the lower surface film-tearing mechanism tears off the release film on the lower surface of the insulation cover. After mounting the insulation cover to the end plate, the end plate with the insulation cover mounted is sent to the upper surface film-tearing mechanism, and the upper surface film-tearing mechanism tears off the release film on the upper surface of the insulation cover.

[0004] The problem with the existing processing method is that the removal of the release films on the upper and lower surfaces of the insulation cover requires an additional processing cycle, thereby reducing the mounting efficiency of the end plate and the insulation cover. Utility Model Content

[0066] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0067] In the existing mounting method of the end plate and the insulating cover, the removal of the release films on the upper and lower surfaces of the insulating cover requires an additional processing cycle, thereby reducing the mounting efficiency of the end plate and the insulating cover.

[0068] To this end, the present application provides an end plate supply device, which is used to attach the insulation cover to the end plate. Release films are applied to the upper and lower surfaces of the insulation cover, and one end of the release film is formed with a film tearing end extending outward from the insulation cover.

[0069] like Figure 1 to Figure 2 As shown, the end plate supply device in the embodiment of the present application includes an end plate feeding mechanism 1, an insulation cover feeding mechanism 2, a lower surface film tearing mechanism 3, a transfer mechanism 4, an end plate unloading mechanism 5 and a flipping mechanism 6, wherein:

[0070] The transfer mechanism 4 includes a first translation module 41 and a transfer fixture 42 mounted on the first translation module 41. The transfer fixture 42 is used to carry the end plate 100. The first translation module 41 is used to drive the transfer fixture 42 to transfer the end plate 100. At least a mounting station and a material unloading station are arranged on the transfer path of the transfer fixture 42. The first translation module 41 can adopt various types of linear modules, such as a linear module composed of a motor, a screw rod, and a screw rod nut, etc., as long as it can drive the transfer fixture 42 to reciprocate and translate.

[0071] The end plate loading mechanism 1 is used to synchronously load two end plates 100 in a horizontal state onto the transfer tooling 42 located at the mounting station.

[0072] The insulating cover feeding mechanism 2 is used to synchronously transport the two insulating covers to the side of the lower surface film tearing mechanism 3, and make the film tearing ends of the release films on the lower surfaces of the two insulating covers face the lower surface film tearing mechanism 3. The lower surface film tearing mechanism 3 is used to tear off the release films on the lower surfaces of the two insulating covers.

[0073] The insulating cover feeding mechanism 2 is also used to mount the two insulating covers with the release films on the lower surfaces removed respectively onto the two end plates 100 located at the mounting station, and to remove the release films on the upper surfaces of the insulating covers.

[0074] The end plate unloading mechanism 5 is used to pick up two end plates 100 with insulation covers attached thereto from the transfer tooling 42 located at the unloading station, and to transport the picked-up two end plates 100 to the turning mechanism 6 .

[0075] The flipping mechanism 6 is used to synchronously flip the two end plates 100 to a vertical state, and to place the two insulating covers mounted on the two end plates 100 opposite to each other.

[0076] The specific working process of the end plate supply device in the embodiment of the present application is as follows:

[0077] First, the first translation module 41 transfers the transfer tool 42 to the mounting station.

[0078] Next, the end plate feeding mechanism 1 synchronously feeds the two end plates 100 in a horizontal state onto the transfer tooling 42. Simultaneously, the insulation cover feeding mechanism 2 moves the two insulation covers to the side of the lower surface film tearing mechanism 3. After the lower surface film tearing mechanism 3 tears off the release films on the lower surfaces of the two insulation covers, the insulation cover feeding mechanism 2 then attaches the two insulation covers 200 to the two end plates 100 located on the transfer tooling 42, and tears off the release films on the upper surfaces of the two insulation covers 200.

[0079] Next, the first translation module 41 transfers the transfer tool 42 carrying the two end plates 100 to the unloading station. The end plate unloading mechanism 5 picks up the two end plates 100 with the insulation cover attached from the transfer tool 42 and transports the picked up two end plates 100 to the flip mechanism 6.

[0080] Finally, the flipping mechanism 6 flips the two end plates 100 to a vertical state, and places the two insulating covers mounted on the two end plates 100 opposite to each other.

[0081] It can be seen that the end plate supply device provided in the embodiment of the present application, wherein the insulating cover feeding mechanism 2 can automatically tear off the release film on the upper surface of the insulating cover after the insulating cover is mounted on the end plate, without the need to send the end plate with the insulating cover mounted to the upper surface film tearing station for additional film tearing operations, thereby improving the mounting efficiency of the insulating cover and the end plate. In particular, the present application realizes the synchronous supply of two end plates with insulating covers required for the battery cell module, thereby improving the assembly efficiency of the battery cell module in the later stage.

[0082] Continue to refer Figure 1 and Figure 2 As shown, optionally, an appearance inspection station located between the mounting station and the unloading station is also provided on the transfer path of the transfer tool 42. Correspondingly, the end plate supply device in the embodiment of the present application also includes an appearance inspection mechanism 7 provided at the appearance inspection station, and the appearance inspection mechanism 7 is used to perform appearance inspection on the end plate with the insulation cover mounted thereon to determine whether the insulation cover is mounted properly.

[0083] Optional, such as Figure 1 As shown, the end plate supply device in the embodiment of the present application further includes an end plate storage mechanism 8 and an insulation cover storage mechanism 9. The end plate loading mechanism 1 picks up two end plates 100 from the end plate storage mechanism 8, and synchronously loads the two end plates 100 in a horizontal state onto the transfer tool 42. The insulation cover loading mechanism 2 picks up two insulation covers from the insulation cover storage mechanism 9, and synchronously transports the two insulation covers to the side of the lower surface film tearing mechanism 3.

[0084] like Figure 3 As shown, optionally, the end plate feeding mechanism 1 includes a second translation module 11, a first lifting module 12, a second lifting module 13, a first suction cup assembly 14 and a second suction cup assembly 15, wherein: the first lifting module 12 and the second lifting module 13 are connected side by side to the movable part of the second translation module 11, the first suction cup assembly 14 is connected to the movable part of the first lifting module 12, and the second suction cup group 15 is connected to the movable part of the second lifting module 13.

[0085] The second translation module 11 is used to drive the first suction cup assembly 14 and the second suction cup assembly 15 to translate synchronously, and the first lifting module 12 and the second lifting module 13 are respectively used to drive the first suction cup assembly 14 and the second suction cup assembly 15 to rise and fall, thereby driving the first suction cup assembly 14 and the second suction cup assembly 15 to suck an end plate respectively, and feed the sucked end plates onto the transfer tooling 42 located at the mounting station.

[0086] Such arrangement enables the end plate feeding mechanism 1 to pick up two end plates and feed the two end plates synchronously to the transfer tool 42 located at the mounting station. Figure 3 In the illustrated embodiment, the insulating cover storage mechanism 9 comprises at least two material racks arranged side by side, each of which is stacked with end plates 100. The loading process of the end plate loading mechanism 1 is as follows:

[0087] First, the second translation module 11 drives the first suction cup assembly 14 and the second suction cup assembly 15 to translate synchronously to above the insulating cover storage mechanism 9, and makes the first suction cup assembly 14 and the second suction cup assembly 15 located directly above one of the material racks respectively.

[0088] Next, the first lifting module 12 drives the first suction cup assembly 14 to lift and lower, so that the first suction cup assembly 14 sucks an end plate from the corresponding material rack. The second lifting module 13 drives the second suction cup assembly 15 to lift and lower, so that the second suction cup assembly 15 sucks an end plate from the corresponding material rack.

[0089] Subsequently, the second translation module 11 drives the first suction cup assembly 14 and the second suction cup assembly 15 to translate synchronously to above the mounting station.

[0090] Next, the first lifting module 12 and the second lifting module 13 drive the first suction cup assembly 14 and the second suction cup assembly 15 to rise and fall respectively, and the first suction cup assembly 14 and the second suction cup assembly 15 release the sucked end plates to the transfer tooling 42 located at the mounting station respectively.

[0091] The second translation module 11, the first lifting module 12, and the second lifting module 13 can all adopt various types of linear modules, such as a linear module composed of a motor, a lead screw, and a lead screw nut, or a linear module composed of a cylinder, a slide rail, and a slider.

[0092] Optionally, the first suction cup assembly 14 and the second suction cup assembly 15 have the same structure. Taking the first suction cup assembly 14 as an example, Figure 4As shown, it includes a first connecting plate 141, a first buffer connecting member 142 and a first suction cup 143, wherein the first connecting plate 141 is connected to the movable part of the first lifting module 12, the upper end of the first buffer connecting member 142 is connected to the first connecting plate 141, and the first suction cup 143 is connected to the lower end of the first buffer connecting member 141. When the first lifting module 12 drives the first connecting plate 141 to descend, the first suction cup 143 presses against the end plate to be picked up to absorb the end plate, and the first buffer connecting member shrinks under pressure.

[0093] Since the first suction cup 143 is connected to the first connecting plate 141 via the first buffer connector 142, even if there is an angle between the adsorption surface of the first suction cup 143 and the surface of the end plate to be picked up, when the first suction cup 143 is pressed against the end plate under the drive of the first lifting module 12, the first buffer connector 142 is compressed and contracted to implement adaptive adjustment of the pressing angle of the first suction cup 143, ultimately ensuring that the adsorption surface of the first suction cup 143 is tightly against the end plate to implement the suction of the end plate.

[0094] Optionally, the first buffer connector 142 includes a guide rod and a spring, wherein the upper end of the guide rod can be slidably connected to the first connecting plate 141, and the lower end of the guide rod is fixedly connected to the first suction cup 143. The spring is sleeved on the guide rod, and the upper and lower ends of the spring abut against the first connecting plate 141 and the first suction cup 143 respectively.

[0095] Optionally, the first suction cup assembly 14 further includes a suction sensing assembly, which includes a photoelectric switch 144 and a sensing sheet 145, wherein the photoelectric switch 144 is disposed on one of the first connecting plate 141 and the first suction cup 143 (for example, Figure 4 The sensing sheet 145 is disposed on the other of the first connecting plate 141 and the first suction cup 143 (eg, Figure 4 When the first buffer connection member 142 is compressed and contracted, the sensing sheet 135 approaches the photoelectric switch to trigger the photoelectric switch. When the first buffer connection member 142 loses pressure and rebounds, the sensing sheet 135 moves away from the photoelectric switch.

[0096] By setting up a suction sensing component, it can be determined whether the first suction cup 143 is sucked onto the end plate. When the first suction cup 143 is sucked onto the end plate, the sensing sheet 135 approaches the photoelectric switch to trigger the photoelectric switch, and the first lifting module 12 stops working to avoid damaging the end plate.

[0097] like Figure 5As shown, optionally, the insulating cover feeding mechanism 2 includes a moving mechanism 21, a first conveying part 22 and a second conveying part 23, wherein: the first conveying part 22 and the second conveying part 23 are connected side by side to the movable part of the moving mechanism 21. The moving mechanism 21 is used to drive the first conveying part 22 and the second conveying part 23 to move synchronously, so as to drive the first conveying part 22 and the second conveying part 23 to respectively attach an insulating cover to the corresponding end plate 100, and to tear off the release film on the upper surface of the insulating cover after the insulating cover is attached.

[0098] The moving mechanism 21 can adopt various moving mechanisms that can at least synchronously drive the first conveying part 22 and the second conveying part 23 to translate and lift, such as a multi-axis robot arm, a driving device composed of an X-axis translation drive module, a Y-axis translation drive module and a Z-axis lifting module, etc.

[0099] Optionally, the first transport portion 22 and the second transport portion 23 have the same structure. Taking the first transport portion 22 as an example, Figure 6 As shown, it includes a mounting plate 221 and a transport assembly 222 and a film tearing assembly 223 arranged side by side on the mounting plate 221, wherein: the mounting plate 221 is connected to the movable part of the moving mechanism 21. The transport assembly 222 includes a third lifting module 224, a second connecting plate 225, a second buffer connecting piece 226 and a second suction cup 227, wherein the third lifting module 224 is connected to the mounting plate 221, the second connecting plate 225 is connected to the movable part of the third lifting module 224, the upper end of the second buffer connecting piece 226 is connected to the second connecting plate 225, and the second suction cup 227 is connected to the lower end of the second buffer connecting piece 226. The film tearing assembly 223 includes a fourth lifting module 228, a double-headed cylinder 229 and two first clamps 220, wherein the fourth lifting module 228 is installed on the mounting plate 221, the double-headed cylinder 229 is installed on the movable end of the fourth lifting module 228, and the two first clamps 220 are respectively installed on the two movable ends of the double-headed cylinder 229, and the clamping ends of the two first clamps 220 face the second suction cup 227.

[0100] The working process of the first transport unit 22 is as follows:

[0101] First, the first conveying unit 22 is driven by the moving mechanism 21 to move above the insulating cover to be picked up.

[0102] Next, the third lifting module 224 drives the second suction cup 227 to descend, so as to drive the second suction cup 227 to absorb the insulation cover 200. After absorbing the insulation cover 200, the third lifting module 224 drives the second suction cup 227 to rise and reset. At the same time, the fourth lifting module 228 drives the first clamping jaw 220 to rise to avoid the insulation cover 200.

[0103] Next, the first transporting portion 22 is driven by the moving mechanism 21 to move to the side of the lower surface film tearing mechanism 3 , and makes the film tearing ends 201 of the release film on the lower surface of the insulation cover 200 face the lower surface film tearing mechanism 3 .

[0104] After the lower surface film tearing mechanism 3 tears off the release film on the lower surface of the insulating cover, the first conveying portion 22 is driven by the moving mechanism 21 to move above the transfer tool 42 located at the mounting station.

[0105] Next, the third lifting module 224 drives the second suction cup 227 to descend, so as to drive the second suction cup 227 to mount the insulation cover 200 on the end plate of the transfer tool 42. After the mounting of the insulation cover 200 is completed, the third lifting module 224 drives the second suction cup 227 to ascend and reset.

[0106] Next, the fourth lifting module 228 drives the two first clamps 220 to descend to extend the two first clamps 220, and the moving mechanism 21 drives the two first clamps 220 to move to a position flush with the tearing end 202 of the release film on the upper surface of the insulation cover 200. The double-headed cylinder 229 then drives the two first clamps 220 to clamp the tearing end 202 of the release film on the upper surface of the insulation cover 200.

[0107] Finally, the moving mechanism 21 drives the two first clamping jaws 220 to rise, so that the two first clamping jaws 220 tear off the release film on the upper surface of the insulation cover 200 from the insulation cover.

[0108] Since the structure and working process of the second conveying part 23 are completely the same as those of the first conveying part 22 , they will not be described in detail in this specification.

[0109] like Figure 7 As shown, optionally, the lower surface film-tearing mechanism 3 includes a first film-tearing portion 31, a second film-tearing portion 32 and a recovery container 33, wherein: the first film-tearing portion 31 and the second film-tearing portion 32 are arranged side by side above the recovery container 33, and the first film-tearing portion 31 and the second film-tearing portion 32 are provided with a first film-tearing position and a second film-tearing position on their outer sides respectively. The insulating cover feeding mechanism 2 transports the two insulating covers to the first film-tearing position and the second film-tearing position respectively, the first film-tearing portion 31 is configured to clamp the film-tearing end 201 of the release film on the lower surface of the insulating cover 200 located at the first film-tearing position, and the second film-tearing portion 32 is configured to clamp the film-tearing end 201 of the release film 200 on the lower surface of the insulating cover at the second film-tearing position. Subsequently, the insulating cover feeding mechanism 2 pulls the two insulating covers 200 obliquely, so that the release films on the lower surfaces of the two insulating covers 200 are separated from the insulating covers and fall into the recovery container 33.

[0110] Optionally, the first film-tearing part 31 and the second film-tearing part 32 have the same structure. Taking the first film-tearing part 31 as an example, it includes a rotating component 311 and a second clamping jaw 312, wherein: the second clamping jaw 312 is installed on the driving end of the rotating component 311, and the second clamping jaw 312 is used to clamp the film-tearing end 201 of the release film on the lower surface of the insulating cover 200. The rotating component 311 is used to drive the second clamping jaw 312 to rotate downward to drive the second clamping jaw 312 to pull the release film downward. In this way, when the insulating cover feeding mechanism 2 pulls the insulating cover obliquely, the release film on the lower surface of the insulating cover can quickly detach from the insulating cover.

[0111] like Figure 5 and Figure 8 As shown, optionally, the transfer mechanism 4 includes two transfer fixtures 42 arranged side by side, each of which is used to carry an end plate 100. The transfer fixture 42 includes a bottom plate 421, a plurality of support blocks 422, a first regularization component 423, a second regularization component 424 and an adsorption component 425, wherein:

[0112] A plurality of support blocks 422 are arranged circumferentially on the bottom plate for supporting the end plates. Figure 8 In the illustrated embodiment, four support blocks 422 are provided in total, each support block 422 is used to support a corner of the end plate, and in addition, a slot for fixing the corner of the end plate is provided on the support block 422 .

[0113] The first regularization component 423 and the second regularization component 424 are arranged at the adjacent two side edges of the bottom plate 421. The first regularization component 423 and the second regularization component 424 are used to cooperate in regularizing the two adjacent side edges of the end plate, thereby completing the position correction of the end plate. Optionally, the first regularization component 423 and the second regularization component 424 both include a regularization cylinder and a regularization plate connected to the regularization cylinder. When the regularization cylinder drives the regularization plate to translate toward the corresponding side edge of the end plate, it presses against the side edge to regularize the side edge.

[0114] The adsorbent 425 is disposed on the bottom plate 421. After the first regularization component 424 and the second regularization component 425 complete the regularization of the end plate, the adsorbent 425 adsorbs and fixes the end plate to facilitate the subsequent insulating cover mounting operation. When the first transport unit 22 peels off the release film on the upper surface of the insulating cover mounted on the battery cell carried by the transfer tool 42, the adsorbent 425 can also prevent the battery cell from moving with the first transport unit 22. The adsorbent 425 can be, for example, a suction cup.

[0115] like Figure 2 and Fig. 9As shown, optionally, the flip mechanism 6 includes a third translation module 61, a support plate 62, a first flip fixture 63, a second flip fixture 64 and a distance driving unit 65, wherein the support plate 62 is connected to the movable part of the third translation module 61, and the distance driving unit 65 is arranged on the support plate 62. The first flip fixture 63 and the second flip fixture 64 are arranged side by side on the support plate 62, and at least one of the first flip fixture 63 and the second flip fixture 64 is slidably connected to the support plate 62 and connected to the driving end of the distance driving unit 65. The third translation module 61 is used to drive the support plate 62 to translate, so that the support plate 62 is close to or away from the blanking station. The first flip fixture 63 and the second flip fixture 64 are respectively used to carry an end plate and drive the end plate to flip. The distance driving unit 65 is used to drive at least one of the first flip fixture 63 and the second flip fixture 64 to slide, so as to implement the distance adjustment of the first flip fixture 63 and the second flip fixture 64.

[0116] The optional working process of the turning mechanism 6 is as follows:

[0117] In the initial state, the support plate 62 is close to the unloading station, the first flipping tool 63 and the second flipping tool 64 are close to each other, and the distance between them matches the distance between the two end plates 100 on the transfer tool 42.

[0118] After the end plate unloading mechanism 5 picks up two end plates 100 with insulation covers mounted on them from the transfer tooling 42 , it places the two end plates 100 with insulation covers mounted on the first flip tooling 63 and the second flip tooling 64 , respectively, and the first flip tooling 63 and the second flip tooling 64 fix the end plates 100 .

[0119] Then, the third translation module 61 drives the support plate 62 to move away from the support plate 62. After moving into position, the first flipping fixture 63 and the second flipping fixture 64 flip 180 degrees toward each other, so that the two end plates 100 flip to a vertical state, and the two insulation covers on the two end plates 100 are placed opposite to each other.

[0120] Finally, the spacing drive unit 65 drives at least one of the first flipping tooling 63 and the second flipping tooling 64 to slide, so as to adjust the spacing between the two end plates 100 to a target value, which target value is, for example, equivalent to the spacing between the two ends of the battery cell module. In this way, the two end plates 100 can be directly and synchronously mounted to the two ends of the battery cell.

[0121] The first flip fixture 63 and the second flip fixture 64 have the same structure. Taking the first flip fixture 63 as an example, it holds the mounting bracket, the adsorption plate and the flip driving member, wherein the mounting bracket is set on the support plate 62, the adsorption plate is rotatably connected to the mounting bracket and connected to the driving end of the flip driving member, the adsorption plate is used to receive and adsorb the end plate placed by the end plate unloading mechanism 5, and the flip driving member is used to drive the adsorption fixed end to flip, so as to implement the flipping operation of the end plate. The third translation module 61 and the spacing driving unit 65 can both adopt existing linear driving modules of various structures.

[0122] like Fig.10 As shown, optionally, the end plate supply device in the embodiment of the present application further includes a laser engraving mechanism 10 located outside the flipping mechanism 6 , and the laser engraving mechanism 10 includes an engraver 101 and a light source assembly 102 .

[0123] The second turning tool 64 includes a base 641, a turning motor 642 and a support plate 643, wherein: the base 641 of the second turning tool 64 is mounted on the support plate 62, the turning motor 642 is mounted on the base 641, and the support plate 643 is rotatably mounted on the base 641, and the support plate 643 is used to carry and fix the end plate sent by the end plate unloading mechanism 5. The turning motor 642 is used to drive the support plate 643 and the end plate to turn over.

[0124] The code engraver 101 and the light source assembly 102 are installed side by side on the outer side of the second flip tool 64, and a clearance gap 644 is opened on the supporting plate 643 for the laser emitted by the code engraver 101 to pass through.

[0125] When the flip motor 642 drives the support plate 643 and the end plate thereon to flip to a vertical state, the laser emitted by the encoder 101 passes through the clearance gap 644 on the support plate 643 and engraves a code on the end plate, and the light source assembly 102 is used to illuminate the portion of the end plate to be engraved.

[0126] By arranging a laser engraving mechanism 100 composed of an engraver 101 and a light source assembly 102 outside the flip mechanism 6, when the flip mechanism 6 flips the driving end plate to a vertical state, the laser engraving mechanism 100 immediately performs the engraving operation on the end plate. Therefore, it is no longer necessary to transport the end plate to the engraving station through a transport device to perform the engraving operation, thereby reducing equipment costs and improving production efficiency.

[0127] Optionally, a holder is provided at each of the four corners of the support plate 643, and each holder is provided with a step groove for an end corner of the end plate to fit in. The support plate 643 is also provided with a suction cup assembly for adsorbing and fixing the end plate on the support plate 643, and the installation position of the suction cup assembly will avoid the clearance notch 644 on the support plate 643 to avoid affecting the normal operation of the encoder 101.

[0128] The present application is described in sufficient detail above with certain particularity. It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, rather than by the above description in the embodiments.
