[0003] The existing end plate loading method is to attach the insulating cover to the inner surface of the end plate in advance, and then store the end plate in a material basket.

[0070] 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.

[0071] The existing end plate loading method requires taking out two end plates from the material basket one by one each time, tearing off the film of the two end plates in turn, turning them over and attaching them to the two end surfaces of the battery cell module. The loading efficiency is low, and the end plates are easily damaged during storage, transportation and removal from the material basket.

[0072] To this end, the present application provides an end plate loading device, which is used to attach an insulation cover to the end plate, and release films are applied to the upper and lower surfaces of the insulation cover.

[0073] like Figure 1 and Figure 2 As shown, the end plate feeding device in the embodiment of the present application includes a first handling mechanism 1, a conveying mechanism 2, a flipping mechanism 3, an insulating cover mounting mechanism, a front film tearing mechanism 7, a fourth handling mechanism 8 and an end plate adjustment mechanism 9, wherein:

[0074] The first conveying mechanism 1 is used to convey the end plate with the outer surface facing upward to the loading end of the conveying mechanism 2. The conveying mechanism 2 is used to convey the end plate. The conveying path of the conveying mechanism 2 is sequentially provided with a flipping station, a mounting station, a front film tearing station and a unloading station.

[0075] The turning mechanism 3 is arranged at the turning station, and is used to turn the end plate located at the turning station so that the inner surface faces upward.

[0076] The insulating cover mounting mechanism is used to tear off the release film on the lower surface of the insulating cover and mount the insulating cover onto the inner surface of the end plate located at the mounting station.

[0077] The front film tearing mechanism 7 is arranged outside the front film tearing station, and is used to tear off the release film on the upper surface of the insulating cover attached to the end plate.

[0078] The fourth transport mechanism 8 is used to pick up two continuously transported end plates with insulation covers mounted thereon from the unloading station, and to transport the two picked-up end plates to the end plate adjustment mechanism 9 .

[0079] The end plate adjustment mechanism 9 is used to synchronously flip the two end plates to an upright state so that the inner surfaces of the two end plates face each other. The end plate adjustment mechanism 9 is also used to adjust the distance between the two end plates to a predetermined value.

[0080] The optional working process of the end plate feeding device in the embodiment of the present application is as follows:

[0081] The first transport mechanism 1 transports the end plate with the outer surface facing upward to the loading end of the conveying mechanism 2, and the conveying mechanism 2 transports the end plate so that the end plate passes through the flipping station, the mounting station, the front film tearing station and the unloading station in sequence.

[0082] When the end plate reaches the flipping station, the flipping mechanism 3 flips the end plate to face the inner surface upward, and the inner surface is the surface of the end plate to be glued. 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, making the lower surface of the insulation cover sticky.

[0083] When the end plate with the inner surface facing upward arrives at the mounting station, the insulating cover mounting mechanism mounts the insulating cover with the release film on the lower surface removed onto the inner surface of the end plate.

[0084] When the end plate reaches the front film tearing station, the front film tearing mechanism 7 tears off the release film on the upper surface of the insulating cover attached to the end plate.

[0085] The fourth transport mechanism 8 picks up two continuously transported end plates with insulation covers mounted thereon from the unloading station, and transports the two picked-up end plates to the end plate adjustment mechanism 9 .

[0086] Finally, the end plate adjustment mechanism 9 flips the two end plates to an upright state so that the inner side surfaces of the two end plates face each other, and adjusts the distance between the two end plates to a predetermined value.

[0087] It can be seen that the end plate loading device of the embodiment of the present application can implement the synchronous supply of two end plates with insulating covers required for the battery cell module, and adjust the distance between the two end plates to a predetermined value, and make the inner surfaces of the two end plates face each other. In this way, the end plate mounting equipment in the subsequent process can directly mount the two end plates on the two end surfaces of the battery cell module, thereby improving the end plate mounting efficiency.

[0088] In addition, by using the end plate loading device of the embodiment of the present application, there is no need to store, transport and remove the end plates after the insulation cover is mounted, thereby reducing the risk of end plate damage.

[0089] like Figure 1 and Figure 2As shown, optionally, the insulating cover mounting mechanism includes a second conveying mechanism 4, a back film tearing mechanism 5, a regularization platform (not shown in the figure) and a third conveying mechanism 6, wherein: the second conveying mechanism 4 is used to pick up the insulating cover from the material box 120, and convey the insulating cover to the side of the back film tearing mechanism 5, and the back film tearing mechanism 5 is used to tear off the release film on the lower surface of the insulating cover. The second conveying mechanism 4 is also used to convey the insulating cover with the release film on the lower surface to the regularization platform. The regularization platform is used to regularize the insulating cover with the release film on the lower surface torn off, so as to correct the position of the insulating cover. The third conveying mechanism 6 is used to convey and mount the regularized insulating cover on the inner surface of the end plate located at the mounting station.

[0090] Optionally, the back film tearing mechanism 5 includes a rotating assembly and a first clamping jaw assembly, wherein: the first clamping jaw assembly is installed on the driving end of the rotating assembly. When the second transporting mechanism 4 transports the insulating cover to the side of the back film tearing mechanism 5, the first clamping jaw assembly clamps the release film on the lower surface of the insulating cover, and the rotating assembly then drives the first clamping jaw assembly to rotate downward, thereby driving the first clamping jaw assembly to pull the release film downward. At the same time, the second transporting mechanism 4 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.

[0091] like Figure 3 As shown, optionally, the first transport mechanism 1 includes a first translation drive module 11, a first lifting drive module 12, a rotation drive module 13 and a first adsorption assembly 14, wherein: the first lifting drive module 12 is connected to the movable part of the first translation drive module 11, the rotation drive module 13 is connected to the movable part of the first lifting drive module 12, and the first adsorption assembly 14 is connected to the movable part of the rotation drive module 13. The first translation drive module 11 and the first lifting drive module 12 are used to cooperate in driving the first adsorption assembly 14 to translate and lift, so as to drive the first adsorption assembly 14 to absorb the end plate with the outer surface facing upward, and transport the absorbed end plate to the feeding end of the conveying mechanism 2. The rotation drive module 13 is used to drive the first adsorption assembly 14 to rotate in a horizontal plane, so as to adjust the orientation of the end plate.

[0092] It can be seen that, through the cooperative driving of the first translation driving module 11 and the first lifting driving module 12, the first adsorption assembly 14 realizes the absorption of the end plate and the transport of the end plate to the loading end of the conveying mechanism 2. The rotation driving module 13 realizes the orientation adjustment of the end plate, so that the orientations of the two adjacent end plates loaded on the loading end of the conveying mechanism 2 are opposite, and finally the inner surfaces of the two end plates after the flipping are opposite.

[0093] The first translation drive module 11 and the first lifting drive module 12 can adopt various types of linear drive 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.

[0094] Optionally, the structure of the second conveying mechanism 4 is the same as that of the first conveying mechanism 1. In this way, the second conveying mechanism 4 can smoothly pick up the insulation cover from the material box 120, and convey the insulation cover to the side of the back film tearing mechanism 5, and convey the insulation cover with the release film on the lower surface to the regular platform. In addition, the second conveying mechanism 4 can adjust the orientation of the insulation cover during the conveying 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.

[0095] Since the third transport mechanism 6 only needs to transport and mount the neatly-formed insulation cover on the inner surface of the end plate at the mounting station, it does not need to adjust the angle of the insulation cover. Therefore, the third transport mechanism 6 can only include a translation drive module, a lifting drive module and an adsorption component, and the translation drive module and the lifting drive module cooperate to drive the adsorption component to translate and lift, thereby driving the adsorption component to absorb the neatly-formed insulation cover from the regular platform and mount the insulation cover on the inner surface of the end plate at the mounting station.

[0096] like Figure 5 As shown, optionally, the front film tearing mechanism 7 includes a second translation driving module 71, a second lifting driving module 72 and a second clamping jaw assembly 73, wherein: the second lifting driving module 72 is connected to the movable part of the second translation driving module 71, and the second clamping jaw assembly 73 is connected to the movable part of the second lifting driving module 72. The second translation driving module 71 and the second lifting driving module 72 are used to cooperate to drive the second clamping jaw assembly 73 to translate and lift, so as to drive the second clamping jaw assembly 73 to clamp and pull upward the release film on the upper surface of the insulation cover, so as to tear off the release film on the upper surface of the insulation cover.

[0097] When the end plate reaches the front film tearing station under the conveyance of the conveying mechanism 2, the second translation driving module 71 and the second lifting driving module 72 cooperate to drive the second clamping jaw group 73 to move, so that the second clamping jaw group 73 clamps the tearing end of the release film on the upper surface of the insulation cover. Then, the second translation driving module 71 and the second lifting driving module 72 cooperate to drive the second clamping jaw group 73 to move, thereby driving the second clamping jaw group 73 to pull the release film on the upper surface of the insulation cover upward, thereby tearing off the release film on the upper surface of the insulation cover.

[0098] Optionally, the second clamping jaw group 73 includes a clamping jaw cylinder 731 and a clamping jaw 732 , and the clamping jaw cylinder 731 drives the clamping jaw 732 to clamp and release the release film on the upper surface of the insulating cover.

[0099] The second translation drive module 71 and the second lifting drive module 72 can adopt various types of linear drive 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.

[0100] like Figure 1 and Figure 4 As shown, optionally, the conveying mechanism 2 includes a first conveying section 21 and a second conveying section 22, wherein the second conveying section 22 is located at the rear of the first conveying section 21, and a flipping station is formed between the second conveying section 22 and the first conveying section 21. The flipping mechanism 3 includes a first mounting bracket 31, a first flipping driving member 32 and an adsorption plate 33, wherein: the first flipping driving member 32 is arranged on the first mounting bracket 31, the adsorption plate 33 is rotatably connected to the first mounting bracket 31 and is transmission-connected to the first flipping driving member 32, and the first flipping driving member 32 is used to drive the adsorption plate 33 to flip toward the first conveying section 21 or the second conveying section 22. When the adsorption plate 33 flips toward the first conveying section 21, it docks with the discharge end of the first conveying section 21, so that the end plate with the outer surface facing upward outputted by the first conveying section 21 can smoothly transition to the adsorption plate 33 and be adsorbed by the adsorption plate 33. Next, the adsorption plate 33 is turned over toward the second conveying section 22 , so that the adsorption plate 33 turns the adsorbed end plate to the loading end of the second conveying section 22 , so that the inner surface of the end plate is turned upward.

[0101] Of course, the conveying mechanism 2 can also be configured as a continuous and uninterrupted conveying line, and the flipping mechanism 3 is arranged above or on the side of the conveying line. When the end plate is conveyed to the flipping station, the flipping mechanism 3 picks up the end plate from the flipping station, flips the end plate so that the inner surface faces upward, and then puts the end plate back onto the conveying mechanism 2.

[0102] like Figure 6 As shown, optionally, the fourth transport mechanism 8 includes a third translation drive module 81, a third lifting drive module 82, a fourth lifting drive module 83, a third clamping jaw assembly 84 and a fourth clamping jaw assembly 85, wherein: the third lifting drive module 82 and the fourth lifting drive module 83 are connected side by side to the movable part of the third translation drive module 81, the third clamping jaw assembly 84 is connected to the movable part of the third lifting drive module 82, and the fourth clamping jaw assembly 85 is connected to the movable part of the fourth lifting drive module 83.

[0107] like Figure 7 As shown, optionally, the end plate adjustment mechanism 9 includes a fourth translation drive module 91, a mounting plate 92, a first end plate flip assembly 93, a second end plate flip assembly 94 and a distance adjustment drive module 95, wherein: the mounting plate 92 is connected to the movable part of the fourth translation drive module 91, and the distance adjustment drive module 95 is arranged on the mounting plate 92. The first end plate flip assembly 93 and the second end plate flip assembly 94 are slidably connected to the mounting plate 92, and are respectively used to receive an end plate with an insulating cover attached thereto carried by the fourth carrying mechanism 8.

[0111] Next, the fourth translation drive module 91 drives the mounting plate 92 to move away from the unloading station.

[0112] Finally, the distance adjustment drive module 95 drives at least one of the first end plate flipping assembly 93 and the second end plate flipping assembly 94 to slide, thereby adjusting the distance between the two end plates to a predetermined value, which is, for example, equivalent to the distance between the two ends of the battery cell module. In this way, the two end plates can be directly and synchronously mounted to the two ends of the battery cell.

[0113] The fourth translation drive module 91 can adopt various existing linear drive 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.

[0115] like Figure 8 As shown, optionally, the first end plate flip assembly 93 and the second end plate flip assembly 94 have the same structure. Taking the first end plate flip assembly 93 as an example, it includes a second mounting bracket 931, a bearing fixture 932 and a second flip driving member 933, wherein: the second mounting bracket 931 is slidably connected to the mounting plate 92 and is transmission-connected to the pitch-adjusting driving module 95, and the bearing fixture 932 is rotatably connected to the second mounting bracket 931.

[0117] In the initial state, the first tidying component 9323 and the second tidying component 9324 are in a evacuation position away from the center of the bottom plate 9321. When the fourth transport mechanism 8 places the end plate on the plurality of support blocks 9322, Figure 8 In the embodiment, the four support blocks 9322 support one corner of the end plate respectively. Then, the first regularization component 9323 and the second regularization component 9324 push the two adjacent sides of the end plate, thereby completing the position correction of the end plate. Then, the adsorption component adsorbs and fixes the end plate that has completed the position correction. Finally, the end plate can be flipped.

[0118] Both the first tidying component 9323 and the second tidying component 9324 can be tidying plates driven by a motor or a cylinder.
