[0081] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0082] In view of the technical problems of large equipment footprint and low assembly efficiency in existing battery cell module assembly solutions, this invention provides a battery cell module assembly equipment that completes the installation and fixing of mica sheets and end plates at the same station to obtain battery cell modules. Compared with existing battery cell module assembly solutions, the battery cell module assembly equipment of this invention significantly reduces the size and footprint of the equipment, while improving assembly efficiency.

[0083] like Figure 1 As shown, the battery cell module assembly equipment in this embodiment of the invention includes an end plate loading device 1, a battery cell stacking device 2, a first conveying device 3, a mica sheet loading device 4, a second conveying device 5, a fixing device 6, and a battery cell unloading device 7, wherein:

[0084] The end plate feeding device 1 is used to provide a first end plate and a second end plate. The end plate feeding device 1 is also used to remove the release film on the first end plate and the second end plate to expose the adhesive surfaces of the first end plate and the second end plate.

[0085] The cell stacking device 2 is used to provide a cell assembly made up of stacked cells.

[0086] The first conveying device 3 is used for picking up the first end plate and the second end plate with exposed adhesive surfaces from the end plate feeding device 1 and picking up two battery cell assemblies from the battery cell stacking device 2, and the first conveying device 3 is also used for conveying the picked first end plate, the second end plate and the two battery cell assemblies to the fixing device 6, wherein the first end plate and the second end plate on the fixing device 6 are respectively located on the opposite first side and the second side of the two battery cell assemblies, and the adhesive surfaces of the first end plate and the second end plate are placed towards the two battery cell assemblies, and a gap is kept between the two battery cell assemblies.

[0087] The mica sheet feeding device 4 is used for at least providing the mica sheet after the gluing is completed.

[0088] The second conveying device 5 is used for picking up the mica sheet from the mica sheet feeding device 4 and placing the picked mica sheet into the gap between the two battery cell assemblies on the fixing device 6.

[0089] The fixing device 6 is used for pressing the two battery cell assemblies together to make the mica sheet adhere to the battery cell assemblies, and the fixing device 6 is also used for pressing the first end plate and the second end plate against the battery cell assemblies to make the first end plate and the second end plate adhere to the battery cell assemblies, thereby obtaining the battery cell module.

[0090] The second conveying device 6 is also used for picking up the battery cell module from the fixing device 6 and conveying the picked battery cell module to the battery cell discharging device 7.

[0091] The battery cell discharging device 7 is used for outputting the battery cell module.

[0092] It can be seen that the battery cell module assembling equipment provided by the present application uniformly conveys the battery cell assembly, the mica sheet and the end plate to the fixing device, and then the fixing device installs and fixes the mica sheet and the end plate to the battery cell assembly at the same station to obtain the battery cell module. Compared with the prior art which needs to implement the mica sheet installation and the end plate installation at different stations, the present application greatly reduces the volume and the floor area of the equipment and improves the assembling efficiency.

[0093] Optionally, in an implementable embodiment, after the fixing device installs and fixes the mica sheet and the end plate to the battery cell assembly, a manual or steel belt installation mechanism is used to wrap the steel mesh belt outside the battery cell module to increase the overall stability of the battery cell module.

[0094] As known by those skilled in the art, for some types of battery cell assemblies, in addition to the need to install end plates on two opposite side walls, side plates also need to be installed on the other two opposite side walls to replace the steel mesh belt to fix the battery cell module.

[0095] In order to realize the automatic installation of the side plates, optionally, the mica sheet loading device 4 is further configured to provide the side plates with the adhesive surfaces. The second carrying device 5 is further configured to pick up two side plates from the mica sheet loading device 4 and place the two side plates to the opposite third and fourth sides of the two battery cell assemblies with the adhesive surfaces of the two side plates facing the two battery cell assemblies. The fixing device 6 is further configured to press the two side plates against the two battery cell assemblies to bond the side plates to the battery cell assemblies.

[0096] In the implementation process, after the first carrying device 3 carries the two battery cell assemblies, the first end plate and the second end plate used for assembling the next battery cell module to the fixing device 6, the second carrying device 5 carries the mica sheet and the two side plates to the fixing device 6 at the same time. In this way, the fixing device 6 can simultaneously install the mica sheet, the end plates and the side plates to the battery cell assemblies at the same station to obtain the battery cell module.

[0097] As shown in Figure 11 , optionally, the battery cell module assembling equipment in the implementation of the present application further comprises a welding device 8 configured to weld the two side plates of the two battery cell assemblies after the fixing by the fixing device 6 to the first end plate and the second end plate. In this way, the two end plates and the two side plates form a closed packaging whole, which improves the overall stability of the battery cell module.

[0098] As described above, in some optional embodiments, the mica sheet loading device 4 not only needs to provide the mica sheet with completed adhesive coating, but also needs to provide the side plates with adhesive surfaces. Among them, the two opposite surfaces of the mica sheet need to be coated with adhesive, and the side plate only needs one surface to be coated with adhesive.

[0099] As shown in Figure 2 , optionally, the mica sheet loading device 4 comprises a side plate carrying mechanism 41, a mica sheet carrying mechanism 42, a carrying mechanism 43, a side plate conveying mechanism 44, a mica sheet conveying mechanism 45 and an adhesive coating mechanism 46, wherein:

[0100] The side plate carrying mechanism 41 is configured to carry the side plates, and the mica sheet carrying mechanism 42 is configured to carry the mica sheets.

[0101] The carrying mechanism 43 is configured to carry the side plates on the side plate carrying mechanism 41 to the side plate conveying mechanism 44, and the side plate conveying mechanism 44 is configured to convey the side plates so that the side plates pass below the adhesive coating mechanism 46, and the adhesive coating mechanism 46 is configured to implement the adhesive coating of one surface of the side plates.

[0102] The carrying mechanism 43 is also used for carrying the mica sheet on the mica sheet carrying mechanism 42 to the mica sheet conveying mechanism 45, and the mica sheet conveying mechanism 45 is used for conveying the mica sheet so that the mica sheet passes below the gluing mechanism 46, and the gluing mechanism 46 is used for gluing the two surfaces of the mica sheet.

[0103] The second carrying device 5 picks up two finished side plates from the discharge end of the side plate conveying mechanism 44 and a finished mica sheet from the discharge end of the mica sheet conveying mechanism 45, and carries the two side plates and the mica sheet to the fixing device 6.

[0104] In order to ensure that the gluing mechanism 46 can continuously complete the gluing process of the two surfaces of the mica sheet, the mica sheet conveying mechanism 45 in the embodiment of the present application can also implement the turnover of the mica sheet during the implementation of the conveying process of the mica sheet. Specifically, as shown in Figure 3 The mica sheet conveying mechanism 45 includes a linear driving module 451, a sliding bearing plate 452, and a rotating clamping assembly 453, wherein the sliding bearing plate 452 is connected to the driving end of the linear driving module 451, and the rotating clamping assembly 453 is installed on the sliding bearing plate 452. The linear driving module 451 is used for driving the sliding bearing plate 452 to slide, so as to drive the rotating clamping assembly 453 to clamp and carry the mica sheet carried by the carrying mechanism 43 and convey the mica sheet. The rotating clamping assembly 453 is also used for turning over the mica sheet after the gluing mechanism 46 completes the gluing of one surface of the mica sheet, so that the gluing mechanism 46 implements the gluing of the other surface of the mica sheet.

[0105] It can be seen that by setting the mica sheet conveying mechanism 45, the mica sheet conveying mechanism 45 can receive the mica sheet carried by the carrying mechanism 43 and automatically convey the mica sheet to the gluing mechanism 46. In addition, the mica sheet conveying mechanism 45 also realizes the turnover of the mica sheet, so that the gluing mechanism 46 can continuously implement the gluing of the two surfaces of the mica sheet.

[0106] As shown in Figure 4 Optionally, the end plate feeding device 1 in the embodiment of the present application includes an end plate carrying part 11, an end plate carrying part 12, and an end plate conveying part 13, wherein the end plate carrying part 11 is used for storing the first end plate and the second end plate. The end plate carrying part 12 is used for carrying the first end plate and the second end plate stored in the end plate carrying part 11 to the end plate conveying part 12 and tearing off the release film on the first end plate and the second end plate. The end plate conveying part 13 is used for conveying the first end plate and the second end plate with the release film torn off towards the first carrying device 3.

[0107] It can be seen that through the cooperation of the end plate carrying part 11, the end plate carrying part 12, and the end plate conveying part 13, the end plate feeding device 1 realizes the automatic supply of the first end plate and the second end plate with the adhesive surface exposed.

[0108] The end plate carrying part 12 needs to implement both picking up and carrying of the end plate, and also needs to implement film tearing operation on the end plate. Therefore, an optional implementation structure of the end plate carrying part 12 is provided in the embodiment of the present application, as shown in Figure 5 which comprises a first moving mechanism 121, a suction assembly 122 and a jaw assembly 123, wherein: the suction assembly 122 is connected to the driving end of the first moving mechanism 121, and the jaw assembly 123 is arranged at the end of the suction assembly 122. The suction assembly 122 is configured to suction the first end plate or the second end plate stored in the end plate carrying part under the driving of the first moving mechanism 121, and to place the first end plate or the second end plate on the end plate conveying part 13. The jaw assembly 123 is configured to clamp the release film on the first end plate or the second end plate placed on the end plate conveying part 13, and to tear off the release film under the driving of the first moving mechanism 121.

[0109] The first moving mechanism 121 can be composed of a translation driving module, a lifting driving module and a rotation driving module, for example, which can drive the suction assembly 122 and the jaw assembly 123 to translate, lift and rotate. When the jaw assembly 123 clamps the release film on the first end plate or the second end plate, the first moving mechanism 121 first drives the jaw assembly 123 to rotate upward by a certain angle, so that the release film is partially separated from the first end plate or the second end plate, and then the translation driving module and the lifting driving module cooperate to drive the jaw assembly 123 to move obliquely upward relative to the first end plate or the second end plate, so as to tear off the release film.

[0110] Since the first end plate and the second end plate have different structures, in order to realize separate feeding of the first end plate and the second end plate, as shown in Figure 6 optionally, the end plate carrying part 11 comprises a first bottom plate 111, a first mounting plate 112, a first rack 113 and a second rack 114, wherein: the first bottom plate 111 is provided with a sliding rail. The first mounting plate 112 is slidingly connected to the sliding rail and can slide back and forth along the sliding rail to realize position switching between the loading position and the taking position. The first rack 113 and the second rack 114 are arranged side by side on the first mounting plate 112. When the first mounting plate 112 slides to the loading position, the first end plate and the second end plate are respectively stacked on the first rack 113 and the second rack 114. When the first mounting plate 112 slides to the taking position, the end plate carrying part 12 picks up the first end plate from the first rack 112, picks up the second end plate from the second rack 113, and places the picked-up first end plate and second end plate on the end plate conveying part 13.

[0111] Optionally, the end plate conveying part 13 comprises a conveying module 131, a second mounting plate 132, a first adsorbing bearing table 133 and a second adsorbing bearing table 134, wherein the second mounting plate 132 is connected to the driving end of the conveying module 131, and the first adsorbing bearing table 133 and the second adsorbing bearing table 134 are installed side by side on the second mounting plate 132, wherein the first adsorbing bearing table 133 is used for bearing and adsorbing the first end plate, and the second adsorbing bearing table 134 is used for bearing and adsorbing the second end plate.

[0112] The conveying module 131 is used for driving the second mounting plate 132 to move towards the first conveying device 3, so as to convey the first end plate and the second end plate to the first conveying device 3. In addition, since the first end plate and the second end plate are adsorbed and fixed on the first adsorbing bearing table 133 and the second adsorbing bearing table 134, when the film of the first end plate and the second end plate is torn, the first end plate and the second end plate will not move with the end plate conveying part 12.
