[0030] It should be noted that, in this embodiment, the distance between any two adjacent lithium tape preparation boxes 32 is not further limited, and those skilled in the art can set it according to actual conditions.

[0031] On the basis of the above embodiment, as an optional embodiment, the lithium tape preparation box 32 includes a first side plate, a second side plate, a bottom plate and an end plate, the first side plate and the second side plate are arranged in parallel, and the first side plate and the second side plate are arranged in a first direction (i.e. Figure 1 The x-axis direction in the middle, the length direction of the lithium tape) is set, the first side plate, the bottom plate and the end plates are arranged vertically in pairs, the bottom plate is set at the bottom of the lithium tape preparation box 32, and the two end plates are set along the second direction, the bottom plate and the two end plates are respectively connected to the first side plate and the second side plate, enclosing to form a lithium tape preparation box 32 with an opening, wherein the spacing between the two end plates along the first direction is adjustable, and the spacing between the first side plate and the second side plate along the second direction is adjustable, thereby making the length and width dimensions of the lithium tape preparation box 32 adjustable, so that the lithium tape preparation box 32 can match lithium tapes 100 of different sizes, so that the lithium tape loading device can be compatible with lithium tapes of different sizes, thereby expanding the scope of application of the lithium tape loading device.

[0032] Specifically, combined Figure 4As shown, the first side plate includes a first connecting plate 321 and a second connecting plate 322, the second connecting plate 322 is provided with a first mounting hole 3221, and multiple first mounting holes 3221 are arranged at intervals along the first direction, the first connecting plate 321 is provided with a first adjustment hole 3211, the first connecting plate 321 can be moved along the arrangement direction of the multiple first mounting holes 3221, and the first connecting plate 321 and the second connecting plate 322 can be connected together through the first adjustment hole 3211 and the first mounting hole 3221. The end plates include a first end plate 324 and a second end plate 325, which are arranged opposite each other at the ends of the first side plate along the first direction. The first end plate 324 is connected to the first connecting plate 321, and the second end plate 325 is connected to the second connecting plate 322. Therefore, when the first connecting plate 321 moves along the arrangement direction of the plurality of first mounting holes 3221, the first end plate 324 can move along with the first connecting plate 321 along the first direction, thereby adjusting the spacing between the first end plate 324 and the second end plate 325, making the spacing between the two end plates along the first direction adjustable. As an optional embodiment, the lithium tape preparation box 32 also includes a first locking member, which passes through the first adjustment hole 3211 and the first mounting hole 3221 to lock the first connecting plate 321 and the second connecting plate 322 together. Thus, when the first connecting plate 321 is moved to a predetermined length along the arrangement direction of the plurality of first mounting holes 3221, the first locking member passes through the first adjustment hole 3211 and the first mounting hole 3221, locking the first connecting plate 321 and the second connecting plate 322 together, thereby limiting the lengthwise dimension of the lithium tape preparation box 32. As an alternative embodiment, the first locking member is a screw or a bolt.

[0033] It should be noted that, in this embodiment, the spacing distance of the first mounting holes 3221 is not further limited, and those skilled in the art may set it according to actual conditions.

[0034] Based on the above embodiment, as an optional embodiment, the second connecting plate 322 includes a first connecting portion and a second connecting portion. The second connecting portion is higher than the first connecting portion, making the second connecting plate 322 L-shaped. A plurality of first mounting holes 3221 are arranged on the first connecting portion at intervals along the first direction. The first connecting portion is connected to the first connecting plate 321, and the second connecting portion is connected to the second end plate 325. Thus, the L-shape of the second connecting plate 322 helps reduce friction when sucking the lithium ribbon 100, making it easier to suck the lithium ribbon 100 and facilitating timely monitoring of the remaining amount of lithium ribbon 100 in the lithium ribbon preparation box 32.

[0035] The second side plate 323 is provided with a second mounting hole at one end near the first end plate 324, and a third mounting hole is provided at one end near the second end plate 325. The first end plate 324 is provided with a second adjustment hole, and the second end plate 325 is provided with a third adjustment hole 3251. The second side plate 324 can move along the second adjustment hole and the third adjustment hole 3251, and one end of the second side plate 324 is connected to the first end plate 324 through the second mounting hole and the second adjustment hole, and the other end of the second side plate 324 is connected to the second end plate 325 through the third mounting hole and the third adjustment hole 3251. The second adjustment hole and the third adjustment hole 3251 can be adjustment holes of the same size and shape, and the second adjustment hole and the third adjustment hole 3251 are both extended along the second direction. Thus, when the second side plate 324 moves along the second adjustment hole and the third adjustment hole 3251, the spacing between the first side plate 323 can be adjusted, so that the width direction of the lithium tape preparation box 32 is adjustable. As an optional embodiment, the lithium tape preparation box 32 also includes a second locking member and a third locking member. The second locking member passes through the second mounting hole and the second adjustment hole to lock one end of the second side plate 324 to the first end plate 324, thereby connecting the two together. The third locking member passes through the third mounting hole and the third adjustment hole 3251 to lock the other end of the second side plate 324 to the second end plate 325. Thus, when the second side plate 323 moves in the second direction to a preset width, the second and third locking members lock the second side plate 323 to the first and second end plates 324 and 325, thereby limiting the width dimension of the lithium tape preparation box 32. As an optional embodiment, the second locking member is a screw or bolt, and the third locking member is a screw or bolt.

[0036] In this embodiment, the second side plate 323 can adopt the same structure as the first side plate, and the second side plate 323 can also be provided with multiple mounting holes arranged at intervals along the first direction, so as to make it easier to adjust the length direction of the lithium tape preparation box 32.

[0037] Based on the above embodiment, as an optional embodiment, the first adjustment hole 3211 is a waist-shaped hole or an elliptical hole, and / or the second adjustment hole is a waist-shaped hole or an elliptical hole, and / or the third adjustment hole 3251 is a waist-shaped hole or an elliptical hole. Therefore, setting the first adjustment hole 3211, the second adjustment hole, and the third adjustment hole 3251 as waist-shaped holes or elliptical holes not only helps to improve the flexibility of adjusting the length and width directions of the lithium tape preparation box 32, making the lithium tape preparation box 32 compatible with lithium tapes 100 of more sizes, but also improves the stability of the connection between the various components of the lithium tape preparation box 32 and improves the structural strength of the lithium tape preparation box 32.

[0038] Based on the above embodiment, as an optional implementation, the lithium tape preparation box 32 also includes a gripping portion 326, which is connected to the second end plate 325. Thus, the gripping portion 326 is provided on the lithium tape preparation box 32 to facilitate the staff to hold the lithium tape preparation box 32.

[0039] On the basis of the above embodiment, as an optional embodiment, the lithium tape preparation assembly 30 further includes a baffle 33, two baffles 33 are both provided on the preparation box mounting plate 31, and the two baffles 33 are respectively provided at both ends of the arrangement direction of the lithium tape preparation boxes 32 of the preparation box group, and the two baffles 33 can move relative to each other along the second direction, so that the two baffles 33 are respectively in contact with the two lithium tape preparation boxes 32 located at the ends of the preparation box group. Thus, by providing the two baffles 33, the position of the lithium tape preparation boxes 32 in the preparation box group can be restricted to prevent the position of the lithium tape preparation boxes 32 located at the ends from being offset. Exemplarily, the preparation box group includes two lithium tape preparation boxes 32. For the sake of convenience of description, one of them is named the first lithium tape preparation box and the other is named the second lithium tape preparation box. Both baffles 33 can be moved along the second direction to make the two baffles 33 approach each other or move away from each other. When the two baffles 33 approach each other, one of the baffles 33 can abut against the first side plate of the first lithium tape preparation box, and the other baffle 33 can abut against the second side plate of the second lithium tape preparation box, thereby restricting the first lithium tape preparation box and the second lithium tape preparation box between the two baffles 33.

[0040] Based on the above embodiment, as an optional implementation method, Figure 2 As shown, the lithium tape preparation assembly 30 further includes two third drive members 34, each of which is disposed on a side of the preparation box mounting plate 31 facing away from the lithium tape preparation box 32. Each third drive member 34 is connected to the baffle 33 and is configured to drive the baffle 33 to move in the second direction. As an alternative embodiment, the third drive member 34 is a cylinder.

[0041] Based on the above embodiment, as an optional implementation method, Figure 3 As shown, the lithium tape preparation assembly 30 also includes a photoelectric sensor 35. The photoelectric sensor 35 is arranged on the side of the preparation box mounting plate 31 away from the lithium tape preparation box 32. The number of photoelectric sensors 35 is the same as the number of lithium tape preparation boxes 32, and the photoelectric sensors 35 are arranged one-to-one with the lithium tape preparation boxes 32. The photoelectric sensor 35 is used to detect whether the corresponding lithium tape preparation box 32 contains a lithium tape 100. If the photoelectric sensor 35 detects that the corresponding lithium tape preparation box 32 does not contain a lithium tape 100, the lithium tape loading device can issue a prompt to remind the staff to refill the lithium tape preparation box 32.

[0042] On the basis of the above embodiment, as an optional embodiment, the material picking drive member includes a first drive member 22, a first mounting seat 23 and a second drive member 24. The first drive member 24 is connected to the first mounting seat 23. The first drive member 22 is used to drive the first mounting seat 23 to move along the second direction. The second drive member 24 and the material picking suction cup 21 are arranged on the first mounting seat 23. Therefore, when the first drive member 22 drives the first mounting seat 23 to move along the second direction, the second drive member 24 and the material picking suction cup 21 also move along the second direction with the first mounting seat 23. The second drive member 24 is connected to the material picking suction cup 21. The second drive member 24 is used to drive the material picking suction cup 21 to move along the third direction (i.e. Figure 1 Thus, the first driving member 22 and the second driving member 24 can drive the material picking suction cup 21 to move along the second direction and the third direction, so that the material picking suction cup 21 can pick up the lithium ribbon 100 in the lithium ribbon preparation box 32.

[0043] In this embodiment, the first and second drive members 24 can be cylinders or motors. They can also be coupled with mechanical transmission structures such as screws, gears, cylinders, chains, or timing belts for better drive. Alternatively, the first drive member 22 can be a motor and the second drive member 24 can be a cylinder. Using a motor as the first drive member 22 further improves the positioning accuracy of lithium ribbon loading.

[0044] Based on the above embodiment, as an alternative embodiment, at least two pick-up suction cups 21 are spaced apart along the first direction, each pick-up suction cup 21 is connected to the second driving member 24, and each pick-up suction cup 21 is used to pick up the lithium ribbon 100. This helps to improve the stability of the pick-up suction cups 21 in adhering to the lithium ribbon 100. As an alternative embodiment, the pick-up suction cups 21 can be vacuum suction cups.

[0045] The following combination Figures 1 to 3 The working principle of the lithium strip feeding device of this embodiment is described as follows:

[0046] The lithium tape preparation box 32 filled with lithium tapes 100 is manually placed on the preparation box mounting plate 31, and the two baffles 33 are moved along the second direction so that the two baffles 33 are respectively in contact with the two lithium tape preparation boxes 32 located at the ends of the preparation box group, thereby completing the positioning of the lithium tape preparation box 32. The first driving member 22 drives the first mounting seat 23 to move along the second direction, driving the second driving member 24 and the material picking suction cup 21 to move along the second direction so that the material picking suction cup 21 reaches above one of the lithium tape preparation boxes 32. The second driving member 24 drives the material picking suction cup 21 to move downward along the third direction, and the material picking suction cup 21 absorbs the lithium tape 100 in the lithium tape preparation box 32. Subsequently, the second driving member 24 drives the material picking suction cup 21 to move upward along the third direction, and the first driving member 22 drives the first mounting seat 23 to move along the third direction. The first driving member 22 and the second driving member 24 drive the material taking suction cup 21 to reach the top of the next lithium tape preparation box 32, suck the lithium tape 100 in the lithium tape preparation box 32, and manually replenish the last empty lithium tape preparation box 32 to realize the replacement of the lithium tape preparation box 32 without stopping the machine.
