[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] See Figures 1 to 6 As shown, one embodiment of this application discloses a medium-duty pitch device that can effectively improve production efficiency.

[0032] The following will combine Figures 1 to 6 The present application provides a detailed explanation and description of the intermediate torque transfer device disclosed in one embodiment. In the following embodiments, the workpiece is described using electrode 1 as an example. It is worth understanding that the stacked intermediate torque transfer mechanism of the present application embodiment can also be used in the intermediate torque transfer process of other workpieces, and is not limited here.

[0033] like Figures 1 to 6 As shown, one embodiment of this application discloses a pitch-changing device, which includes a bracket 100 and a pickup assembly 200.

[0034] Specifically, the pickup assembly 200 includes a plurality of pickup mechanisms respectively connected to the support 100, each pickup mechanism being able to move relative to the support 100 in a first direction, wherein each pickup mechanism is used to independently pick up a workpiece.

[0035] It should be pointed out that the first direction refers to Figure 1 The X direction is shown in the diagram. Each pickup mechanism can move independently relative to the support 100 along the X direction. That is, the spacing between the pickup mechanisms can be adjusted according to actual needs.

[0036] In the transfer distance changing device provided by the embodiments of the present application, each pickup mechanism can independently pick up a workpiece, and each pickup mechanism can independently move in the first direction. In this way, when each pickup mechanism picks up a workpiece on the previous conveying line, the distance between each pickup mechanism can be adjusted correspondingly to realize batch pickup of workpieces. When conveying, the distance between each pickup mechanism is adjusted to make each workpiece spaced apart from each other, and then the distance between each pickup mechanism is changed and the workpieces are placed on the next conveying line when moving to the next conveying line. In this way, batch transfer of workpieces can be realized while meeting the conveying distance requirement in the process of conveying the pole piece 1, which helps to reduce the time of feeding and discharging, thereby improving the production efficiency.

[0037] In some embodiments of the present application, referring to Figure 1 and Figure 2 , the transfer distance changing device further comprises a driving mechanism 310 mounted on the support 100, and the driving mechanism 310 is configured to drive each pickup mechanism to move. Specifically, the driving mechanism 310 can drive each pickup mechanism to independently move in the first direction, and can change the distance between different pickup mechanisms.

[0038] In some embodiments of the present application, referring to Figures 1 to 6 , the pickup mechanism comprises a bracket 210, a conveying arm 220 and a pickup part 230. The bracket 210 is connected with the driving mechanism 310, the conveying arm 220 is connected with the bracket 210, and the pickup part 230 is mounted on the conveying arm 220 and configured to adsorb the workpiece. The driving mechanism 310 drives the bracket 210 to move in the first direction to drive the conveying arm 220 and the pickup part 230 to move in the first direction. The pickup part 230 is arranged at a position corresponding to the position of the pole piece 1 on the conveying line, so that the pickup part 230 can pick up the pole piece 1 on the conveying line.

[0039] In a possible implementation, referring to Figures 1 to 6 , the pickup mechanism comprises a lifting driving module 240 mounted on the bracket 210, and the lifting driving module 240 is configured to drive the conveying arm 220 to lift. When the driving mechanism 310 drives the conveying arm 220 to move above the pole piece 1 to be picked up, the lifting driving module 240 is started to drive the conveying arm 220 and the pickup part 230 to approach the pole piece 1, so as to complete the pickup of the pole piece 1.

[0040] In the embodiment, the lifting driving module 240 is specifically a pneumatic cylinder.

[0041] In some embodiments of the present application, the pickup mechanism comprises a sliding rail and sliding block module 250, and the conveying arm 220 is slidingly connected with the bracket 210 through the sliding rail and sliding block module 250. In this way, the stability of the movement of the conveying arm 220 can be improved.

[0042] The slide rail and the slide block are connected in sliding mode.

[0043] In a possible implementation, the slide rail is directly connected to the bracket 210, and the slide block is directly connected to the conveying arm 220. It should be understood that the slide rail can be one part of the bracket 210, that is, the slide rail is formed in the bracket 210; of course, the slide rail can also be a separate structure from the bracket 210, and then is fixedly connected to the bracket 210 through assembly. Similarly, the slide block can be a structure formed in the conveying arm 220, or can be a separate structure from the conveying arm 220.

[0044] In another possible implementation, the slide block is directly connected to the bracket 210, and the slide rail is directly connected to the conveying arm 220.

[0045] In some embodiments of the present application, the pickup part 230 includes a vacuum chuck assembly. The vacuum chuck assembly is used to fix the pole piece 1 by abutting against the surface of the pole piece 1 and turning on the vacuum adsorption. The vacuum chuck assembly can include a chuck or other structure capable of realizing vacuum adsorption.

[0046] In a possible implementation, referring to Figures 4 to 6 , the vacuum chuck assembly includes a first chuck member 231 and a second chuck member 232. The first chuck member 231 is fixedly connected to the conveying arm 220, and the second chuck member 232 is adjustably connected to the conveying arm 220. The first chuck member 231 and the second chuck member 232 jointly form an adsorption plane. The adsorption plane is used to abut against the pole piece 1 to realize adsorption and fixation of the pole piece 1. The second chuck member 232 is adjustably connected to the conveying arm 220, so that the relative position of the second chuck member 232 on the conveying arm 220 can be changed to adapt to the pickup work of pole pieces 1 of different sizes. In this embodiment, the first chuck member 231 and the second chuck member 232 are both chucks.

[0047] In actual application, a plurality of connection holes can be arranged on the conveying arm 220. The second chuck member 232 is connected to different connection holes to change the relative position of the second chuck member 232 on the conveying arm 220.

[0048] In some other embodiments, the pickup part 230 can be a gripper or a pneumatic gripper, or other mechanisms capable of realizing a grabbing action, to realize grabbing of the workpiece.

[0049] In some embodiments of the present application, referring to Figures 1 to 6The driving mechanism 310 comprises a linear slide motor installed on the support 100 and a mover component 311 cooperating with the linear slide motor. The carrier 210 of each pickup mechanism is connected with the mover component 311. Each mover component 311 cooperates with the linear slide motor to drive the independent sliding of each carrier 210. In this way, the individual driving and control of each pickup mechanism can be realized, so that the spacing between each pickup mechanism can be changed to adapt to the actual production work and improve the production efficiency.

[0050] It is worth understanding that in other embodiments of the present application, the pickup mechanisms can also be individually driven by independent driving structures. For example, the driving structure can be a lead screw driving structure, and the pickup mechanisms can move independently through the corresponding lead screw driving structure.

[0051] In some embodiments of the present application, referring to Figures 1 to 3 The plurality of pickup mechanisms are distributed in two layers on the support 100. Specifically, each layer has a plurality of pickup mechanisms, and the pickup mechanisms in the upper and lower layers can independently move in the first direction. In this way, the transmission spacing between the previous transmission line and the next transmission line can be shortened, thereby shortening the length of the production line and facilitating the shortening of the transmission time. At the same time, the plurality of pickup mechanisms in the upper and lower layers can alternately transfer, which facilitates the improvement of the production efficiency. In addition, the distribution of the plurality of pickup mechanisms in the upper and lower layers can also reduce the occupation area of the pickup mechanisms in the plane.

[0052] For example, the transfer distance changing device has upper and lower pickup mechanisms. When each pickup mechanism in the upper layer picks up the pole piece 1 transferred from the previous transmission line, it drives the pole piece 1 to move to the next conveying line. Then, each pickup mechanism in the lower layer can move to the previous transmission line to pick up the pole piece 1 and then move the pole piece 1 to the next transmission line. The alternate transfer of the pickup mechanisms in the upper and lower layers can improve the transfer efficiency of the pole piece 1 and further improve the production efficiency.

[0053] Referring to Figures 1 to 6 The transfer distance changing device comprises a plurality of pickup mechanisms distributed in two layers. Each pickup mechanism is connected with a corresponding linear slide motor. In this way, the pole piece 1 on the previous transmission line can be conveyed to the next transmission line with a smaller spacing, which can reduce the unloading time and the transmission time. At the same time, the spacing between each pickup mechanism can be reduced and approached. After each pickup mechanism adsorbs the corresponding pole piece 1, it is transferred to the next conveying line. During the transfer process, the distance between the plurality of pickup mechanisms can be adjusted to space the plurality of pole pieces 1 apart from each other. In this embodiment, the plurality of pickup mechanisms are distributed in two layers, and the pickup mechanisms in the upper and lower layers can alternately transfer the pole piece 1, thereby improving the production efficiency.

[0054] Another aspect of the present application discloses a battery production device, comprising the transfer device as described above.

[0055] In the battery production device provided by the present application, each pickup mechanism can independently pick up the workpiece, and each pickup mechanism can independently move along the first direction. In this way, when each pickup mechanism picks up the workpiece on the previous conveying line, the spacing between each pickup mechanism can be adjusted correspondingly to realize batch pickup of the workpieces. When conveying, the spacing between each pickup mechanism is adjusted to make each workpiece spaced apart from each other, and then the spacing between each pickup mechanism is changed and the workpieces are placed on the next conveying line when moving to the next conveying line. In this way, batch transfer of the workpieces can be realized while meeting the conveying spacing requirement in the conveying process of the workpieces, the time for feeding and discharging is reduced, and thus the production efficiency is improved.
