[0063] To make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0064] As shown in the drawings, Figure 1 The electric core assembling equipment in the embodiment of the present application comprises an end plate feeding device 1, a first transfer line 2, an electric core stacking device, a first carrying device, a second transfer line 3, a second carrying device 4, a packing device 5, and a third transfer line 6, wherein:

[0065] The end plate feeding device 1 is used for pasting insulating covers to end plates and carrying two end plates pasted with insulating covers to the first transfer line 2 at a time.

[0066] The first transfer line 2 is used for turning over the two end plates to a vertical state so that the insulating covers on the two end plates are opposite to each other, adjusting the distance between the two end plates to a predetermined value, and transferring the two end plates to a first feeding station A.

[0067] The electric core stacking device is located in front of the second transfer line 3, the first carrying device is located between the electric core stacking device and the second transfer line 3, the electric core stacking device is used for stacking electric cores into an electric core module, the first carrying device is used for picking up the electric core module from the electric core stacking device and carrying the electric core module to the second transfer line 3, and the second transfer line 3 is used for transferring the electric core module to a second feeding station B.

[0068] The second carrying device 4 is used for picking up the two end plates from the first feeding station A and picking up the electric core module from the second feeding station B, wherein the picked-up electric core module is located between the picked-up two end plates.

[0069] The second carrying device 4 is also used for carrying the picked-up two end plates and the electric core module to a packing station C of the packing device 5. The packing device 5 is used for bundling and packing the two end plates and the electric core module.

[0070] The second conveying device 4 is also used for picking up the completed battery cell module from the packaging device 5, and conveying the completed battery cell module to a discharging station D of the third transfer line 6, and the third transfer line 6 is used for transferring the completed battery cell module to a subsequent processing station.

[0071] It can be seen that the end plate feeding device and the battery cell stacking device in the battery cell module production equipment of the embodiment of the present application can prepare the end plate attached with the insulating cover and the battery cell module in parallel, and then the second conveying device uniformly conveys the prepared battery cell module and the end plate attached with the insulating cover to the packaging device for packaging, thereby improving the battery cell assembly efficiency.

[0072] As shown in Figure 1 , optionally, the packaging device 5 is provided with two, and correspondingly, the second conveying device 4 is provided with two, and the transfer path of the first transfer line 2 is provided with two first feeding stations A, the transfer path of the second transfer line 3 is provided with two second feeding stations B, and the transfer path of the third transfer line 6 is provided with two discharging stations D. The two second conveying devices 4 respectively pick up the end plate and the battery cell module from the corresponding first feeding station A and the second feeding station B, and convey the picked up end plate and battery cell module to the corresponding packaging device 5, and convey the completed battery cell module to the corresponding discharging station D. In this way, the battery cell assembly efficiency can be further improved.

[0073] Continuing to refer to Figure 1 , optionally, the first transfer line 2, the second transfer line 3, the third transfer line 6 and the packaging device 5 are arranged side by side, and the first transfer line 2, the second transfer line 3 and the third transfer line 6 all transfer along a first horizontal direction (such as the X-axis direction in Figure 1 ). The second conveying device 4 is located above the first transfer line 2, the second transfer line 3, the third transfer line 6 and the packaging device 5, and the second conveying device 4 is conveyed along a second horizontal direction (such as the Y-axis direction in Figure 1 ) perpendicular to the first horizontal direction. The first feeding station A, the second feeding station B, the packaging station C and the discharging station D are all located on the conveying path of the second conveying device 4.

[0074] By arranging the positions of the first transfer line, the second transfer line, the third transfer line, the packaging device, the first feeding station, the second feeding station, the packaging station and the discharging station, the overall size of the equipment is reduced, and when the second conveying device reciprocates along the second horizontal direction, it can pass through the first feeding station, the second feeding station, the packaging station and the discharging station in turn, thereby improving the conveying efficiency.

[0075] As shown in Figure 2As shown, optionally, the end plate feeding device 1 in the embodiment of the present application comprises a first conveying mechanism 11, a conveying mechanism 12, a turnover mechanism 13, an insulation cover mounting mechanism, a front film tearing mechanism 17 and a fourth conveying mechanism 18, wherein:

[0076] The first conveying mechanism 11 is used to convey the end plate with the outer surface upward to the feeding end of the conveying mechanism 12, and the conveying mechanism 12 is used to convey the end plate. The turnover station, the mounting station, the front film tearing station and the discharging station are sequentially arranged on the conveying path of the conveying mechanism 12.

[0077] The turnover mechanism 13 is arranged at the turnover station, and is used to turn over the end plate at the turnover station to have the inner surface upward.

[0078] The insulation cover mounting mechanism is used to tear off the release film on the lower surface of the insulation cover, and to mount the insulation cover on the inner surface of the end plate at the mounting station.

[0079] The front film tearing mechanism 17 is arranged outside the front film tearing station, and is used to tear off the release film on the upper surface of the insulation cover mounted on the battery cell.

[0080] The fourth conveying mechanism 18 is used to pick up two continuously conveyed end plates with the insulation cover mounted thereon from the discharging station, and to convey the picked up two end plates to the first transfer line 2.

[0081] The optional working process of the end plate feeding device 1 is as follows:

[0082] The first conveying mechanism 11 conveys the end plate with the outer surface upward to the feeding end of the conveying mechanism 12, and the conveying mechanism 12 conveys the end plate so that the end plate sequentially passes through the turnover station, the mounting station, the front film tearing station and the discharging station.

[0083] When the end plate reaches the turnover station, the turnover mechanism 13 turns over the end plate to have the inner surface upward, which is the surface to be pasted with glue. At the same time, the insulation cover mounting mechanism picks up an insulation cover and tears off the release film on the lower surface of the insulation cover, so that the lower surface of the insulation cover has adhesion.

[0084] When the end plate with the inner surface upward reaches the mounting station, the insulation cover mounting mechanism mounts the insulation cover with the lower surface release film torn off on the inner surface of the end plate.

[0085] When the end plate reaches the front film tearing station, the front film tearing mechanism 17 tears off the release film on the upper surface of the insulation cover mounted on the end plate.

[0086] The fourth conveying mechanism 18 picks up two continuously conveyed end plates with the insulation cover mounted thereon from the discharging station, and conveys the picked up two end plates to the first transfer line 2.

[0087] It can be seen that through the above setting of the end plate feeding device 1, the end plate feeding device 1 can implement the synchronous supply of the two end plates with insulating covers required by the battery cell module.

[0088] With reference to the accompanying drawings, the end plate feeding device 1 comprises a first conveying mechanism 10, a first conveying mechanism 11, a conveying mechanism 12, a first conveying line 2, a second conveying line 3 and a feeding mechanism 4. Figure 2 As shown in the drawings, optionally, the insulating cover mounting mechanism comprises a second conveying mechanism 14, a back film tearing mechanism 15, a shaping platform and a third conveying mechanism 16, wherein: the second conveying mechanism 14 is used to pick up the insulating cover from the box and convey the insulating cover to the side of the back film tearing mechanism 15, and the back film tearing mechanism 15 is used to tear off the release film on the lower surface of the insulating cover. The second conveying mechanism 14 is also used to convey the insulating cover with the lower surface release film torn off to the shaping platform. The shaping platform is used to shape the insulating cover with the lower surface release film torn off, and the third conveying mechanism 16 is used to convey and mount the shaped insulating cover to the inner side surface of the end plate located at the mounting station.

[0089] Optionally, the back film tearing mechanism 15 comprises a rotating assembly and a first jaw assembly, wherein: the first jaw assembly is installed on the driving end of the rotating assembly. When the second conveying mechanism 14 conveys the insulating cover to the side of the back film tearing mechanism 15, the first jaw assembly clamps the release film on the lower surface of the insulating cover, and the rotating assembly then drives the first jaw assembly to rotate downward, thereby pulling the release film downward with the first jaw assembly. At the same time, the second conveying mechanism 14 pulls the insulating cover obliquely, so that the release film on the lower surface of the insulating cover is completely separated from the insulating cover.

[0090] Optionally, the first conveying mechanism 11 comprises a translation driving part, a lifting driving part, a rotating driving part and a suction accessory, wherein: the lifting driving part is connected to the moving part of the translation driving part, the rotating driving part is connected to the moving part of the lifting driving part, and the suction accessory is connected to the moving part of the rotating driving part. The translation driving part and the lifting driving part are used to cooperate to drive the suction accessory to translate and lift, so as to suck the end plate with the outer side surface upward and convey the sucked end plate to the feeding end of the conveying mechanism 12. The rotating driving part is used to drive the suction accessory to rotate in the horizontal plane, so as to adjust the orientation of the end plate.

[0091] It can be seen that through the cooperation of the translation driving part and the lifting driving part, the suction accessory realizes the suction of the end plate and the conveying of the end plate to the feeding end of the conveying mechanism 12. The rotating driving part realizes the orientation adjustment of the end plate, so that the orientations of the two adjacent end plates fed to the feeding end of the conveying mechanism 12 are opposite, and finally the orientations of the two end plates after being flipped through the first conveying line 2 are opposite.

[0092] The translation driving part and the lifting driving part can adopt various types of linear driving modules, such as a linear module composed of a motor, a screw rod and a screw nut, or a linear module composed of a pneumatic cylinder, a sliding rail and a sliding block, etc.

[0093] Optionally, the second carrying mechanism 14 has the same structure as the first carrying mechanism 11. In this way, the second carrying mechanism 14 can smoothly pick up the insulation cover from the magazine and carry the insulation cover to the side of the back film tearing mechanism 15, and carry the insulation cover after the lower surface release film is torn off to the regular platform. In addition, the second carrying mechanism 14 can adjust the orientation of the insulation cover during the carrying process, so that the orientation of the insulation cover is consistent with the orientation of the corresponding end plate to be glued on the conveying mechanism 12.

[0094] Since the third carrying mechanism 16 only needs to carry and glue the regular insulation cover to the inner side surface of the end plate at the gluing station, it does not need to implement the angle adjustment of the insulation cover. Therefore, the third carrying mechanism 16 can only include a translation driving part, a lifting driving part, and a suction part, and the translation driving part and the lifting driving part cooperate to drive the suction part to translate and lift, so as to suck the regular insulation cover from the regular platform and glue the insulation cover to the inner side surface of the end plate at the gluing station.

[0095] As shown in Figure 3 Optionally, the first transfer line 2 includes a first conveying track 21, a first mounting plate 22, a first translation driving module 23, a first end plate overturning assembly 24, a second end plate overturning assembly 25, and a distance adjustment driving module 26. The first mounting plate 22 is slidingly connected to the first conveying track 21 and is drivingly connected to the first translation driving module 23. The first end plate overturning assembly 24 and the second end plate overturning assembly 25 are slidingly connected to the first mounting plate 22 and are respectively used to receive an end plate with an insulation cover carried by the end plate feeding device 1. The first end plate overturning assembly 24 and the second end plate overturning assembly 25 are also used to synchronously overturn the two end plates to the vertical state and make the insulation covers on the two end plates opposite. The distance adjustment driving module 26 is used to drive the first end plate overturning assembly 24 and the second end plate overturning assembly 25 to slide towards each other or away from each other, so as to adjust the distance between the two end plates to a predetermined value. The first translation driving module 23 is used to drive the first mounting plate 22 to slide on the first conveying track 21, so as to transfer the two end plates to the first feeding station.

[0096] The optional working process of the first transfer line 2 is as follows:

[0097] In the initial state, the first mounting plate 22 is close to the discharging station, and the first end plate overturning assembly 24 and the second end plate overturning assembly 25 are close to each other, so that the distance between them matches the distance between the adjacent two end plates at the discharging station.
