[0078] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise stated, the orientation words such as "upper" and "lower" generally refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the accompanying drawings; and "inner" and "outer" refer to the outline of the device.

[0079] This application provides a battery production device 1000, which includes a top cover jig 100, a laser coding device, and a transfer device. The laser coding device is used to perform laser coding on the battery top cover in the top cover jig 100. The transfer device can move the top cover jig 100 to the laser coding device. The top cover jig 100 is used to carry the battery top cover.

[0080] It can be understood that in battery production, the battery top cover, the battery cell, and the housing need to be assembled, and after passing through multiple assembly processes and welding, a sealed battery structure can be formed. Among them, the battery top cover also needs to go through a series of processing processes separately to meet the assembly requirements. One of them is battery top cover coding, which is mainly to burn the code with production information in advance on the battery top cover, so that in the subsequent assembly process, each battery can be traced and feedback, or when problems occur, it can also be traced back in time. This is very important for automated and intelligent production.

[0081] The transfer device can transfer the top cover jig 100. The transfer device can be a conveyor belt, a conveyor roller, or a maglev loop. The top cover jig 100 further includes a transfer mechanism 50, and the transfer mechanism 50 can move the top cover jig 100 on the transfer device. Here, a maglev loop is taken as an example for elaboration.

[0082] Please refer to Figure 1 , in an embodiment, the transfer device is a maglev loop. The transfer mechanism 50 of the top cover jig 100 is a maglev mover. After the motor is started, the maglev mover can move on the maglev loop, so as to move the top cover jig 100 to different workstations for processing.

[0083] Please refer to Figure 2, the laser engraving device includes a laser head 310 and a first driving mechanism 320. The laser head 310 is arranged above the top cover engraving station, and the first driving mechanism 320 is arranged below the top cover engraving station. The transfer device moves the top cover jig 100 to the top cover engraving station of the laser engraving device. The output end of the first driving mechanism 320 is connected to the support plate 32, and lifts the driving plate, thereby lifting the first limiting mechanism 20 carrying the battery top cover. During the lifting process of the first limiting mechanism 20, the lifting height of the first driving mechanism 320 can be adjusted so that the distance from the lifted battery top cover to the laser head 310 is adapted to the focal length of the laser head 310. In this embodiment, the yield of battery top cover engraving is improved without adjusting the focal length of the laser head 310.

[0084] The first driving mechanism 320 may be a cylinder, a hydraulic cylinder, a motor or the like.

[0085] See also Figure 3 The present application also proposes a top cover fixture 100, comprising a substrate 10, a first limiting mechanism 20 and a lifting mechanism 30. The substrate 10 is provided with a through hole, which penetrates the substrate 10 along the thickness direction Z of the substrate 10. The first limiting mechanism 20 is provided on one side of the substrate 10, and is used to limit the battery top cover. The lifting mechanism 30 includes a support shaft 31 and a support plate 32.

[0086] The support shaft 31 is at least partially movably disposed in the through hole. One end of the support shaft 31 is connected to the first limiting mechanism 20. The support shaft 31 is used to drive the first limiting mechanism 20 to move closer to or away from the substrate 10 in the thickness direction Z of the substrate 10. The support plate 32 is located on a side of the substrate 10 away from the first limiting mechanism 20, and the support plate 32 is connected to the other end of the support shaft 31.

[0087] In an embodiment of the present invention, by arranging a lifting mechanism 30 in the top cover jig 100, during laser engraving, the lifting mechanism 30 can make the first limiting mechanism 20 approach or move away from the substrate 10, so that the battery top cover located in the first limiting mechanism 20 is adapted to the focal length of the laser engraver, thereby achieving clear laser engraving without adjusting the focal length of the laser engraver, thereby improving the yield rate of laser engraving of the battery top cover, thereby improving the technical problem that the yield rate of battery top cover engraving is affected by the inability of the laser engraver to adjust the focal length.

[0088] See also Figure 3 Optionally, the base plate 10 is provided with a plurality of through holes, and the lifting mechanism 30 includes a plurality of support shafts 31. The plurality of support shafts 31 are respectively provided in the plurality of through holes and connected to the first limiting mechanism 20. A support plate 32 is connected to the plurality of support shafts 31.

[0089] In this embodiment, the arrangement of multiple support shafts 31 can improve the connection stability between the lifting mechanism 30 and the first limiting mechanism 20, avoiding the decrease in the yield rate of laser coding caused by the unstable connection of the lifting mechanism 30.

[0090] Before lifting, the first driving mechanism 320 of the laser coding device is drivingly connected to the support plate 32, driving the support plate 32 to move closer to the substrate 10, so that the support shaft 31 lifts the first limiting mechanism 20 to achieve the lifting of the first limiting mechanism 20. After lifting, the first driving mechanism 320 descends, driving the support plate 32 to descend, so that the support shaft 31 lowers the first limiting mechanism 20.

[0091] Optionally, the lifting mechanism 30 further includes a driving member. The driving member is disposed on the side of the substrate 10 away from the first limiting mechanism 20. The driving member is drivingly connected to the support plate 32 to drive the support plate 32 to move closer to or away from the substrate 10.

[0092] In this embodiment, the driving member can be built into the top cover fixture 100, so that there is no need to provide the first driving mechanism 320 in the laser coding device, eliminating the process of drivingly connecting the first driving mechanism 320 and the support plate 32, and improving the production efficiency.

[0093] Specifically, the driving member can be a cylinder, a hydraulic cylinder or a motor. There is no limitation on the driving member here. Taking the driving member as a cylinder as an example. The driving member can be disposed on the side of the substrate 10 away from the first limiting mechanism 20, and the output end of the driving member is connected to the support plate 32. When the output end of the driving member extends, the support plate 32 moves away from the substrate 10, thereby driving the first limiting mechanism 20 to descend relative to the substrate 10. When the output end of the driving member retracts, the support plate 32 moves closer to the substrate 10, thereby driving the first limiting mechanism 20 to rise relative to the substrate 10.

[0094] Please refer to Figure 4 , optionally, the first limiting mechanism 20 includes a carrier 21 and a first limiting component 22.

[0095] The carrier 21 is connected to the lifting mechanism 30, and the carrier 21 is used to carry the battery top cover. The first limiting component 22 is disposed on the carrier 21 and is used to limit the battery top cover.

[0096] In this embodiment, the carrier 21 is used to carry the battery top cover, and the first limiting component 22 is used to limit the battery top cover, thereby improving the accuracy of laser coding, avoiding deviation in the position of laser coding, or movement of the battery top cover during the coding process, which affects laser coding. The first limiting component 22 can limit the battery top cover in the horizontal direction, and the first limiting component 22 can also limit the battery top cover in the thickness direction Z of the substrate 10. There is no limitation on the limiting method of the first limiting component 22 here.

[0097] Please refer to Figure 5 Optionally, the carrier 21 includes a first carrier plate 211 and a first carrier table 212.

[0098] The first carrier plate 211 is connected to the lifting mechanism 30. The first carrier table 212 is disposed on a side of the first carrier plate 211 away from the substrate 10. A first accommodating cavity 212a is provided on a side of the first carrier table 212 away from the substrate 10. The first accommodating cavity 212a is used to accommodate the battery top cover. Wherein, the first limiting component 22 is used to limit the battery top cover within the first accommodating cavity 212a.

[0099] In this embodiment, when the top cover jig 100 is transported to the laser coding device, the lifting mechanism 30 lifts the first carrier plate 211, thereby lifting the first carrier table 212, and the battery top cover accommodated in the first accommodating cavity 212a is also lifted accordingly. During the processes of lifting, coding, and descending, the first limiting component 22 limits the battery top cover all the time, preventing the battery top cover from moving within the first accommodating cavity 212a, improving the accuracy of laser coding, and thus improving the yield of top cover coding.

[0100] Optionally, the carrier 21 includes a plurality of first carrier tables 212. Among them, the plurality of first carrier tables 212 are disposed on the same first carrier plate 211. The lifting mechanism 30 can lift a plurality of first carrier tables 212 simultaneously by lifting one first carrier plate 211. The plurality of first carrier tables 212 can load a plurality of battery top covers. Since the plurality of battery top covers are lifted, a plurality of laser heads 310 in the laser coding device can code the plurality of battery top covers simultaneously, thereby improving the production efficiency of the battery production equipment 1000.

[0101] Please refer to Figure 6 Optionally, the first limiting component 22 includes a first limiting member 221. The first limiting member 221 is disposed on a side of the first carrier plate 211 away from the substrate 10 and on a side of the first carrier table 212, and is used to limit the battery top cover in a first direction.

[0102] In this embodiment, the first direction can be the thickness direction Z of the substrate 10, and the first direction can also be a direction parallel to the plane of the substrate 10. The first direction is not limited in this embodiment. When the first direction is the thickness direction Z of the substrate 10, the first limiting member 221 can be a pressing plate that presses the battery top cover from top to bottom in the thickness direction Z of the substrate 10 to limit it. When the first direction is a direction parallel to the plane of the substrate 10, the first limiting member 221 can be a clamping block that presses the battery top cover against the inner wall of the first accommodating cavity 212a in the horizontal direction to limit it. For the sake of avoiding redundancy, the subsequent embodiments will take the first limiting member 221 limiting the battery top cover in the horizontal direction as an example for illustration.

[0103] Please refer to Figure 6 Optionally, a first opening 212b is provided on the side of the first carrier 212 close to the first limiting member 221. The first opening 212b communicates with the first accommodation cavity 212a, and a part of the first limiting member 221 can extend into the first accommodation cavity 212a through the first opening 212b.

[0104] In this embodiment, a part of the first limiting member 221 can extend into the first accommodation cavity 212a from the first opening 212b and abut against the side of the battery top cover, so as to press the battery top cover against the inner wall of the first accommodation cavity 212a, achieving the effect of limiting the battery top cover in the horizontal direction. This embodiment can prevent the battery top cover from moving in the accommodation cavity, improve the accuracy of laser coding, and thus improve the yield of top cover coding.

[0105] Please refer to Figure 7 Optionally, the first limiting member 221 includes a first connecting portion 221a, a first clamping block 221b, a first sliding block 221c, and a first elastic member 221d.

[0106] The first connecting portion 221a is located on one side of the first opening 212b. The first clamping block 221b is connected to the end of the first connecting portion 221a away from the substrate 10. The first clamping block 221b can extend into the first accommodation cavity 212a through the first opening 212b. The first sliding block 221c is movably arranged between the first carrier plate 211 and the first carrier 212. The first sliding block 221c is connected to the end of the first connecting portion 221a close to the substrate 10. One end of the first elastic member 221d is fixed to the first carrier plate 211, and the other end of the first elastic member 221d is connected to the first sliding block 221c. The first elastic member 221d extends along the first direction D1 and is used to limit the battery top cover in the first accommodation cavity 212a in the first direction D1.

[0107] In this embodiment, before loading the battery top cover into the first accommodation cavity 212a, it is necessary to push the first sliding block 221c to make the first clamping block 221b extend out of the first accommodation cavity 212a through the first opening 212b. At this time, the first elastic member 221d is in a stretched state. Then the battery top cover is placed into the first accommodation cavity 212a. After placing the battery top cover, release the first sliding block 221c. At this time, the first elastic member 221d returns to its original state from the stretched state, driving the first sliding block 221c to move in the reverse direction, so that the first clamping block 221b extends into the first accommodation cavity 212a again through the first opening 212b and limits the battery top cover placed in the first accommodation cavity 212a. This embodiment can prevent the battery top cover from moving in the first accommodation cavity 212a, improve the accuracy of laser coding, and thus improve the yield of top cover coding.

[0108] Please refer to Figure 6Optionally, the first limiting component 22 further includes a second limiting member 222. The second limiting member 222 is disposed on the side of the first carrier plate 211 away from the substrate 10 and on one side of the first carrying platform 212, and is used to limit the battery top cover in the second direction D2.

[0109] Wherein, the first direction D1 intersects with the second direction D2, and the first limiting member 221 and the second limiting member 222 are arranged at intervals.

[0110] In this embodiment, the first direction may be the thickness direction Z of the substrate 10, and the second direction D2 may be parallel to the direction of the plane of the substrate 10. The first direction D1 and the second direction D2 may also both be parallel to the direction of the plane of the substrate 10. No limitation is made thereto here. For the sake of avoiding redundancy, the subsequent embodiments will be described with the first direction D1 and the second direction D2 both being parallel to the direction of the plane of the substrate 10.

[0111] In this embodiment, the first limiting member 221 and the second limiting member 222 limit the battery top cover in the first accommodating cavity 212a from two horizontal directions, thereby further preventing the battery top cover from moving in the first accommodating cavity 212a, improving the accuracy of laser coding, and thus improving the yield of top cover coding.

[0112] Optionally, a second opening 212c is provided on the side surface of the first carrying platform 212 close to the second limiting member 222. The second opening 212c communicates with the first accommodating cavity 212a. A part of the second limiting member 222 can extend into the first accommodating cavity 212a through the second opening 212c.

[0113] In this embodiment, a part of the second limiting member 222 can extend into the first accommodating cavity 212a from the second opening 212c and abut against the side surface of the battery top cover, so as to simultaneously abut the battery top cover against the two inner walls of the first accommodating cavity 212a with the first limiting member 221, achieving the effect of limiting the battery top cover in two horizontal directions. This embodiment can further prevent the battery top cover from moving in the accommodating cavity, improve the accuracy of laser coding, and thus improve the yield of top cover coding.

[0114] Please refer to Figure 7 Optionally, the second limiting member 222 includes a second connecting portion 222a, a second clamping block 222b, a second sliding block 222c, and a second elastic member (not marked in the figure).

[0115] The second connecting portion 222a is located on one side of the second opening 212c. The second clamping block 222b is connected to one end of the second connecting portion 222a away from the substrate 10. The second clamping block 222b can extend into the first accommodating cavity 212a through the second opening 212c. The second sliding block 222c is movably disposed between the first carrier plate 211 and the first carrier platform 212. The second sliding block 222c is connected to one end of the second connecting portion 222a close to the substrate 10. One end of the second elastic member is fixed to the first carrier plate 211, and the other end of the second elastic member is connected to the second sliding block 222c. The second elastic member extends along the second direction D2 and is used to limit the battery top cover in the first accommodating cavity 212a in the second direction.

[0116] In this embodiment, before loading the battery top cover into the first accommodating cavity 212a, it is necessary to push the first sliding block 221c and the second sliding block 222c respectively, so that the first clamping block 221b and the second clamping block 222b extend out of the first accommodating cavity 212a through the first opening 212b and the second opening 212c respectively. At this time, the first elastic member 221d and the second elastic member are in a stretched state. Then the battery top cover is placed into the first accommodating cavity 212a. After the battery top cover is placed, the first sliding block 221c and the second sliding block 222c are released. At this time, the first elastic member 221d and the second elastic member return to their original state from the stretched state, driving the first sliding block 221c and the second sliding block 222c to move in the reverse direction, so that the first clamping block 221b and the second clamping block 222b extend into the first accommodating cavity 212a again through the first opening 212b and the second opening 212c respectively, and the battery top cover placed in the first accommodating cavity 212a is limited in two horizontal directions. This embodiment can further prevent the battery top cover from moving in the first accommodating cavity 212a, improve the accuracy of laser coding, and thus improve the yield of top cover coding.

[0117] Optionally, a first slide rail and a second slide rail are provided on the side of the first carrier plate 211 away from the substrate 10. The first slide rail extends along the first direction D1, and the first slider 221c is slidably connected to the first slide rail. The second slide rail extends along the second direction D2, and the second slider 222c is slidably connected to the second slide rail. A first follower wheel is provided on the first slider 221c, and a second follower wheel is provided on the second slider 222c. During the process of putting the battery top cover into or taking it out of the first accommodating cavity 212a, the first follower wheel and the second follower wheel can be pushed by the loading manipulator or the unloading manipulator, so that the first slider 221c and the second slider 222c slide along the first slide rail and the second slide rail respectively, so that the first clamping block 221b and the second clamping block 222b extend out of the first accommodating cavity 212a, facilitating the putting in or taking out of the battery top cover. After the battery top cover is put in or taken out, the loading manipulator or the unloading manipulator releases the first follower wheel and the second follower wheel, and relying on the elastic forces of the first elastic member 221d and the second elastic member itself, pulls the first slider 221c and the second slider 222c to move in the reverse direction along the first slide rail and the second slide rail respectively, so that the first clamping block 221b and the second clamping block 222b re-enter the first accommodating cavity 212a. The first elastic member 221d and the second elastic member can be springs.

[0118] Please refer to Figure 5 , optionally, the substrate 10 includes a first part 10a and a second part 10b connected to each other, and the first limiting mechanism 20 is provided on the first part 10a.

[0119] The top cover fixture 100 further includes a second limiting mechanism 40. The second limiting mechanism 40 is provided on the second part 10b, and the second limiting mechanism 40 is used to limit the battery top cover and the vest stacked with the battery top cover.

[0120] In this embodiment, when the laser coding of the battery top cover is completed, the next process needs to load the vest into the top cover fixture 100 to realize the welding of the vest and the battery top cover in the subsequent process. In order to adapt to the vest, the battery top cover needs to be transferred from the first limiting mechanism 20 to the second limiting mechanism 40. The first limiting mechanism 20 and the second limiting mechanism 40 are arranged in the top cover fixture 100. Compared with the first limiting mechanism 20, the second limiting mechanism 40 can limit the battery top cover and the vest at the same time.

[0121] In this embodiment, the structural design of the top cover fixture 100 including the first limiting mechanism 20 and the second limiting mechanism 40 enables the top cover fixture 100 to be applicable to multiple process stations, improves the station compatibility of the top cover fixture 100, and reduces the space occupation of multiple stations. The top cover fixture 100 of this embodiment does not need to be like a traditional top cover fixture that cannot be applied to multiple stations due to poor station compatibility, resulting in the need to set up multiple fixtures for one process, large space occupation, and high cost.

[0122] Please refer toFigure 2 , optionally, the top cover fixture 100 further includes a transfer mechanism 50, and the transfer mechanism 50 is disposed on a side of the second portion 10b away from the second limiting mechanism 40. The lifting mechanism 30 is disposed on the first portion 10a.

[0123] In this embodiment, since the first driving mechanism 320 of the laser coding device needs to drive the lifting mechanism 30 to lift, in order to avoid interference between the first driving mechanism 320 of the laser coding device and the transfer mechanism 50 of the top cover fixture 100, the transfer mechanism 50 is disposed on the second portion 10b in this embodiment, while the lifting mechanism 30 is disposed on the first portion 10a, thereby avoiding interference between the two and improving the structural stability of the top cover fixture 100.

[0124] Please refer to Figure 5 , optionally, the second limiting mechanism 40 includes a second bearing table 41, a positioning pin 42, and a third limiting member 43.

[0125] The second bearing table 41 is disposed on the second portion 10b. A second accommodation cavity 41a is provided on a side of the second bearing table 41 away from the substrate 10. The second accommodation cavity 41a is used to accommodate the battery top cover.

[0126] The positioning pin 42 is disposed on a side of the second bearing table 41 away from the substrate 10 and is located outside the second accommodation cavity 41a for positioning the vest.

[0127] The third limiting member 43 is disposed on the second portion 10b and is located on one side of the second bearing table 41 for limiting the battery top cover and the vest stacked on the battery top cover in the Z direction of the thickness of the substrate 10.

[0128] In this embodiment, the vest is provided with a positioning hole. When the vest is stacked on the battery top cover, the positioning hole of the vest needs to be aligned with the positioning pin 42 on the second bearing table 41 to accurately align the vest with the battery top cover, avoiding unqualified products welded due to inaccurate alignment of the vest and the battery top cover in subsequent processes and improving the production yield of the battery processing equipment.

[0129] After the feeding of the vest is completed, the third limiting member 43 limits the battery top cover and the vest stacked on the battery top cover in the Z direction of the thickness of the substrate 10. So as to weld the battery top cover and the vest subsequently and improve the yield of the welded product.

[0130] Please refer to Figure 7 , optionally, the third limiting member 43 includes a third connecting portion 43a, a limiting block 43b, a third slider 43c, and a third elastic member 43d.

[0131] The third connecting portion 43a is located on one side of the second bearing table 41.

[0132] The limiting block 43b is connected to one end of the third connecting portion 43a away from the substrate 10. The limiting block 43b can extend into the side of the second carrier 41 away from the substrate 10, and is used for limiting the battery top cover and the vest stacked with the battery top cover in the thickness direction Z of the substrate 10.

[0133] The third slider 43c is movably arranged between the second part 10b and the second carrier 41. One end of the third connecting portion 43a close to the substrate 10 is connected to the third slider 43c.

[0134] One end of the third elastic member 43d is fixed to the second part 10b, and the other end of the third elastic member 43d is connected to the third slider 43c, and is used for making the third connecting portion 43a abut against the side surface of the second carrier 41, so that the limiting block 43b extends into the side of the second carrier 41 away from the substrate 10.

[0135] In this embodiment, before the vest is placed on the second carrier 41, the second driving mechanism (such as a manipulator, a clamping arm and other structures) in the battery processing equipment will transfer the battery top cover from the first accommodating cavity 212a to the second accommodating cavity 41a. During the process of placing the vest on the second carrier 41, first, it is necessary to push the third slider 43c to make the limiting block 43b extend out of the side of the second carrier 41 away from the substrate 10. At this time, the third elastic member 43d is in a stretched state. Then the vest is placed on the second carrier 41 from the side of the second carrier 41 away from the substrate 10, so that the positioning hole of the vest is aligned with the positioning pin 42 on the second carrier 41. After the vest is placed, the third slider 43c is released. At this time, the third elastic member 43d returns to its original state from the stretched state, drives the third slider 43c to move in the reverse direction, makes the limiting block 43b extend into the side of the second carrier 41 away from the substrate 10 again, and limits the battery top cover placed in the second accommodating cavity 41a in the thickness direction Z of the substrate 10. This embodiment can prevent the relative movement between the vest and the battery top cover, avoid unqualified products welded due to the inaccurate alignment of the vest and the battery top cover in the subsequent process, and improve the production yield of the battery processing equipment.

[0136] Optionally, a third slide rail is provided on the second part 10b of the substrate 10. The third slide rail extends along the second direction D2, and the third slider 43c is slidably connected to the third slide rail. A third follower wheel is provided on the third slider 43c. During the process of placing the vest on the second carrier 41, the upper vest manipulator can push the third follower wheel to make the third slider 43c slide along the third slide rail, so that the limiting block 43b extends out of the side of the second carrier 41 away from the substrate 10, facilitating the placement of the vest. After the vest is placed, the upper vest manipulator releases the third follower wheel, and relies on the elastic force of the third elastic member 43d itself to pull the third slider 43c to move in the reverse direction along the third slide rail, so that the limiting block 43b re-enters the side of the second carrier 41 away from the substrate 10. The third elastic member 43d can be a spring.
