The present application configures an anti-reversal member, and when the transfer sheet to be picked up is reversed, the anti-reversal member abuts against the convex bump of the transfer sheet to be picked up, so that a gap is formed between the transfer sheet to be picked up and the picking member, thereby making it difficult for the picking member to pick up the transfer sheet, thereby reducing the possibility that the transfer sheet loading assembly will transport the reversed transfer sheet to the next welding process, thereby improving the yield rate of the battery product.

In some embodiments of the present application, along the first direction, the distance between the second end and the mounting member is a, and the distance between the fourth end and the mounting member is b, wherein b≥a; the first direction is the arrangement direction of the first end and the second end.

Below, the embodiments of the present application are described in detail.

At present, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

During the battery production process, an adapter sheet loading device is required to load the adapter sheet to the welding position for welding the adapter sheet, electrode tab and electrode terminal. Specifically, the adapter sheet in the material box is transferred to the battery cell in sequence for welding through an adapter sheet loading assembly (such as a spider hand or other structure).

However, when the adapter sheet loading assembly picks up the adapter sheet, the adapter sheet in the material box is easily placed upside down with the bulge facing upward, causing the adapter sheet to be welded between the electrode tab and the electrode terminal to be placed upside down. In addition, since the adapter sheets are stacked in the material box and the upper and lower adapter sheets are partially overlapped, when the adapter sheet loading assembly picks up the upper adapter sheet, it is easy to drive the lower adapter sheet to move at the same time, resulting in two or more adapter sheets to be welded between the electrode tab and the electrode terminal. The above two situations seriously affect the quality of the battery after the adapter sheet is welded, resulting in poor product yield.

Therefore, how to reduce the phenomenon of adapter sheet being placed upside down and adapter sheet stacking welding during adapter sheet loading is an important issue in battery production and processing.

In view of this, the present application provides a technical solution, which configures an anti-reverse part and an anti-overlapping part on the adapter sheet loading assembly, and utilizes the cooperation between the anti-reverse part and the convex bump of the adapter sheet after it is placed reversed to limit the position of the adapter sheet after it is placed reversed, thereby reducing the possibility of the loading assembly picking up the adapter sheet after it is placed reversed, and utilizes the anti-overlapping part to offset the adapter sheet under the adapter sheet to be picked up, thereby reducing the possibility of overlapping adapter sheets during loading.

The adapter sheet loading assembly provided in the embodiment of the present application is described below in conjunction with Figures 1-8.

First, in combination with what is shown in Figures 1-4, an embodiment of the present application provides a transfer sheet loading assembly 10, which includes a mounting member 11, a picking member 12 and an anti-reverse member 13, the picking member 12 having a first end 121 and a second end 122 opposite to each other, the first end 121 being connected to the mounting member 11, and the second end 122 being used to pick up a transfer sheet 200 to be picked up; the anti-reverse member 13 and the picking member 12 are located on the same side of the mounting member 11, and have a third end 131 and a fourth end 132 opposite to each other, the third end 131 being connected to the mounting member 11, and the fourth end 132 being used to abut against a convex hump 210 on the surface of the transfer sheet 200 to be picked up, so as to form a gap between the transfer sheet 200 to be picked up and the picking member 12.

The functions of the mounting member 11 of this embodiment include mounting the pick-up member 12 and the anti-reverse member 13, and also connecting the moving assembly 30 of the adapter sheet feeding device 100, and using the moving assembly 30 to drive the mounting member 11, the pick-up member 12 and the anti-reverse member 13 to move. The material of the mounting member 11 can be metal or a polymer material with a certain structural strength, and the shape of the mounting member 11 can be a plate-like member as shown in the figure, and of course it can also be a block or a special-shaped member, etc., which will not be listed in this embodiment.

The number of the picking member 12 of this embodiment can be one or more than one as shown in the figure, and the plurality of picking members 12 are arranged at intervals and installed on the mounting member 11 of this embodiment. The picking member 12 of this embodiment can include an air nozzle in terms of structure, and its picking principle is to use the negative pressure of the air nozzle to suck the adapter. Of course, the picking member 12 can also include a structure such as a mechanical gripper (not shown in the figure) whose picking principle is to grab.

The anti-reverse component 13 of this embodiment can be a rod-like or columnar structure. The material of the anti-reverse component 13 can be metal or a polymer material with a certain structural strength (such as polyethylene, polypropylene, etc.). The anti-reverse component 13 and the picking component 12 can be perpendicular to the surface of the mounting component 11.

As shown in FIG2 , when the adapter sheet 200 to be picked up is placed upside down, the anti-reversal member 13 abuts against the convex bump 210 of the adapter sheet 200 to be picked up, so that a gap is formed between the adapter sheet 200 to be picked up and the picking member 12, thereby making it difficult for the picking member 12 to pick up the adapter sheet. At this time, the alarm component (not shown in the figure) of the adapter sheet loading device 100 can sound an alarm to remind the staff to promptly straighten the upside-down adapter sheet 200 to be picked up, which can reduce the possibility that the adapter sheet loading component 10 will transport the upside-down adapter sheet to the next welding process, thereby improving the yield of the battery product.

As shown in Figures 3 and 4 , in some examples, optionally, along the first direction X, the distance between the second end 122 and the mounting member 11 is a, and the distance between the fourth end 132 and the mounting member 11 is b, where b≥a; the first direction X is the arrangement direction of the first end 121 and the second end 122.

The first direction X mentioned above can be understood as the arrangement direction of the first end 121 and the second end 122 . When the picking member 12 of this embodiment is perpendicular to the upper and lower surfaces of the mounting member 11 , the first direction X is a vertical direction.

In this embodiment, the distance a between the second end 122 and the mounting member 11 can be understood as the height of the anti-reverse member 13 protruding from the mounting member 11, and the distance b between the fourth end 132 and the mounting member 11 can be understood as the height of the picking member 12 protruding from the mounting member 11. When b≥a, this structural design facilitates that when the adapter sheet loading assembly 10 approaches the adapter sheet 200 to be picked up, the anti-reverse member 13 can be abutted against the convex bulge 210 of the inverted adapter sheet 200 to be picked up at the first time.

Of course, b can also be slightly smaller than a, as long as the anti-reverse component 13 can abut against the convex bump 210 of the reversed adapter 200 to be picked up, and a certain gap or interval is generated between the adapter body and the picking component 12 to achieve the anti-reverse effect.

In some examples, optionally, the surface of the adapter sheet 200 to be picked up that is away from the convex hump 210 has a concave 220 corresponding to the convex hump 210 , and the depth of the concave 220 is c, where b≤a+c.

In actual application, and when the picking member 12 of this embodiment is vertically connected to the mounting member 11, the depth direction of the recess 220 of the adapter plate is set along the first direction X in the figure, and the first direction X is a vertical direction. By designing the distance between the fourth end 132 and the mounting member 11 to be less than or equal to the sum of the distance between the second end 122 and the mounting member 11 and the depth of the recess 220, when the picking member 12 picks up the adapter plate 200 to be picked up that is not reversed, the fourth end 132 of the anti-reverse member 13 can be placed in the recess 220, and no gap will be generated between the adapter plate 200 to be picked up and the picking member 12. Therefore, the existence of the anti-reverse member 13 will not affect the picking operation of the picking member 12.

In some examples, optionally, the second end 122 of the anti-reversal member 13 of this embodiment is made of a flexible material.

The flexible material may be rubber, flexible plastic, silicone and other materials. The flexible material may be deformed to a certain extent when in contact with the adapter, thereby reducing damage to the adapter.

Taking the case where the anti-reversal member 13 is performing an inverted transfer sheet 200 to be picked up as an example, when the second end 122 abuts against the convex bump 210 of the inverted transfer sheet 200 to be picked up, the second end 122 is deformed to reduce damage to the convex bump 210. Taking the case where the transfer sheet 200 to be picked up that is not inverted is picked up as an example, when the second end 122 abuts against the concave 220 of the uncorrected transfer sheet 200 to be picked up, the second end 122 is deformed so that the second end 122 is accommodated in the concave 220, which does not affect the picking up of the transfer sheet by the picking member 12, and makes it easier for the picking member 12 to press against the surface of the transfer sheet 200 to be picked up, which is beneficial to the picking up operation of the picking member 12.

In combination with Figures 1, 2, 4 and 5, in some examples, optionally, the adapter sheet loading assembly 10 of the present embodiment further includes an anti-overlapping member 14, the anti-reversal member 13, the anti-overlapping member 14 and the picking member 12 are located on the same side of the mounting member 11, the anti-overlapping member 14 includes a fifth end 141 and a sixth end 142 opposite to each other, the sixth end 142 extends away from the mounting member 11, the distance between the second end 122 and the mounting member 11 is a, the distance between the sixth end 142 and the mounting member 11 is d, d＞a; the first direction X is the arrangement direction of the first end 121 and the second end 122.

The fifth end 141 of this embodiment is connected to the mounting member 11, and a lower-layer adapter sheet 300 is stacked below the adapter sheet 200 to be picked up. The sixth end 142 is used to extend from the adapter sheet 200 to be picked up in a direction away from the mounting member 11, and to abut against the lower-layer adapter sheet 300, so that a gap is formed between the adapter sheet 200 to be picked up and the lower-layer adapter sheet 300 after being picked up.

Optionally, the anti-stacking member 14 and the aforementioned anti-reversal member 13 can be installed on the lower side of the mounting member 11 and perpendicular to the lower surface of the mounting member 11. Similar to the aforementioned anti-reversal member 13, the anti-stacking member 14 of this embodiment can also be approximately rod-shaped or columnar in structure as a whole, and its material can also be metal or a polymer material with a certain structural strength (such as polyethylene, polypropylene, etc.).

It should be noted that the "adapter sheet 200 to be picked up" and the "lower layer adapter sheet 300" described in this embodiment are adapter sheet structures with the same structure, and the two are only different in positional relationship. The above names are distinguished for the convenience of description.

The distance between the sixth end 142 of the present embodiment and the mounting member 11 can be understood as the height of the anti-stacking member 14 protruding downward from the mounting member 11. By designing the distance between the sixth end 142 and the mounting member 11 to be greater than the distance between the second end 122 and the mounting member 11, the height of the anti-stacking member 14 protruding from the mounting member 11 is greater than the height of the picking member 12 protruding from the mounting member 11, which is conducive to the fifth end 141 of the anti-stacking member 14 to abut against the lower adapter plate 300.

As shown in Figure 5, by configuring the anti-stacking member 14, when a lower-layer adapter sheet 300 is stacked below the adapter sheet 200 to be picked up, the lower-layer adapter sheet 300 can be supported, and a gap can be formed with the lower-layer adapter sheet 300 after the adapter sheet 200 to be picked up is picked up by the picking member 12, thereby reducing the possibility that the adapter sheet 200 to be picked up and the lower-layer adapter sheet 300 are taken away by the picking member 12 at the same time, thereby reducing the possibility that the two stacked adapter sheets are conveyed to the next welding process, thereby further improving the product yield of the battery.

In some examples, optionally, the surface of the adapter sheet 200 to be picked up that is away from the convex hump 210 has a concave 220 corresponding to the convex hump 210 , and the depth of the concave 220 is c, where d≥a+c.

By designing the distance between the sixth end 142 and the mounting member 11 to be greater than the sum of the distance between the second end 122 and the mounting member 11 and the depth of the recess 220, when the picking member 12 picks up the upper-layer adapter sheet 200 to be picked up, the sixth end 142 can be abutted against the recess 220 of the lower-layer adapter sheet 300, thereby achieving a gap between the adapter sheet 200 to be picked up and the lower-layer adapter sheet 300 after being picked up by the picking member 12.

Again in conjunction with FIG. 4 , in some examples, optionally, the anti-reversal member 13 and the anti-stack-up member 14 of this embodiment are arranged in parallel and spaced apart along a second direction Y, and the second direction Y intersects with the first direction X.

Along the second direction Y, the distance between the center of the anti-reversal piece 13 and the center of the anti-stack piece 14 is e, and the distance between the center of the convex 210 of the adapter sheet 200 to be picked up and the center of the convex 210 of the lower adapter sheet 300 is f, where e=f.

When the adapter sheets are stacked in the material box 40, the upper and lower layers of adapter sheets are not completely opposite to each other, but the bulge 210 of the lower layer adapter sheet 300 is exposed. At this time, the center of the bulge 210 of the adapter sheet 200 to be picked up and the bulge 210 of the lower layer adapter sheet 300 have the above-mentioned distance f. In order to adapt to this feature, in this embodiment, the distance between the center of the anti-reverse piece 13 and the center of the anti-stacking piece 14 is e. When the shapes of the anti-reverse piece 13 and the anti-stacking piece 14 of this embodiment are both cylindrical as shown in the figure, the centers of the anti-reverse piece 13 and the anti-stacking piece 14 along the second direction Y are the axes of the two.

By adopting the above-mentioned structural design, the center distance between the anti-reverse component 13 and the anti-stacking component 14 is equal to the center distance between the two convex bumps 210 of the two stacked adapter sheets. When the adapter sheets are loaded, the anti-reverse component 13 and the anti-stacking component 14 can be respectively aligned with the convex bumps 210 of the two reversed adapter sheets, or respectively aligned with the recesses 220 of the two non-reversed adapter sheets, so as to achieve the anti-reverse and anti-stacking effects.

In combination with Figures 1, 2, 4, 5 and 6, in some examples, optionally, the adapter sheet loading assembly 10 of the present embodiment further includes a connecting member 15, the connecting member 15 and the picking member 12 are located on the same side of the mounting member 11 and are connected to the mounting member 11, and the anti-reverse member 13 and the anti-overlapping member 14 are respectively connected to the mounting member 11 through the connecting member 15.

The third end 131 of the anti-reversal member 13 of the present embodiment is indirectly connected to the mounting member 11 via the connecting member 15 . Similarly, the fifth end 141 of the anti-stack member 14 of the present embodiment is indirectly connected to the mounting member 11 via the connecting member 15 .

The shape of the connecting member 15 of this embodiment is not limited, and can be approximately rectangular block or plate-shaped, etc. The material of the connecting member 15 is the same as or similar to the aforementioned mounting member 11. The connecting member 15 is mainly used for docking the mounting member 11, the anti-reverse member 13 and the anti-stacking member 14, so as to facilitate the connection between the mounting member 11 and the anti-reverse member 13 and the anti-stacking member 14 respectively.

In some examples, optionally, the connecting member 15 of this embodiment is connected to the mounting member 11 in a manner that its position in the second direction Y is adjustable, and the second direction Y intersects with the arrangement direction of the first end 121 and the second end 122 .

In this embodiment, the second direction Y may be perpendicular to the first direction X. In practical applications, the second direction Y may be a horizontal direction.

The fact that the position of the connecting member 15 in the second direction Y of this embodiment is adjustable can be understood as: the connecting member 15 can move on the mounting member 11 along the second direction Y and can maintain a stable position after the movement.

By designing the connecting member 15 to be positionally adjustable along the second direction Y on the mounting member 11, it is convenient to adjust the positions of the anti-reversal member 13 and the anti-stack member 14, thereby improving the positioning accuracy of the two when they are in contact with the adapter sheet.

In some examples, optionally, the mounting member 11 of the present embodiment is provided with a positioning hole 111 that passes through the mounting member 11 along a first direction X, and the length of the positioning hole 111 extends along a second direction Y, and the first direction X is the arrangement direction of the first end 121 and the second end 122; the connecting member 15 includes a connecting portion 151 and a locking member 152, the locking member 152 is connected to the connecting portion 151 and is located in the positioning hole 111, the locking member 152 can move in the positioning hole 111 along the second direction Y, and is used to lock and fix the connecting portion 151 to the mounting member 11.

Among them, the locking member 152 of this embodiment can be a bolt or a screw. When the locking member 152 of this embodiment is a bolt, the number of the connecting parts 151 of this embodiment can be two as shown in the figure. The two connecting parts 151 are respectively located on both sides of the top of the connecting part 15 along the second direction Y. Each connecting part 151 is provided with at least one screw hole 1511, and each screw hole 1511 matches a bolt. The screw rod portion of the bolt passes through the adjustment hole 111 and is connected to the screw hole 1511. The nut of the bolt is pressed against the top surface of the mounting member 11 when locking, or as shown in the figure, the nut of the bolt is pressed against the limiting wall 1111 in the adjustment hole 111 when locking, so as to realize the locking connection between the connecting part 151 and the mounting member 11. The limiting wall 1111 is arranged along the circumferential direction of the adjustment hole 111, and the thickness is less than the thickness of the mounting member 11 in the first direction X.

When the position of the connecting member 15 needs to be adjusted along the second direction Y, the bolt is screwed to release the lock, and the bolt and the connecting member 15 can be moved. The structure is simple and easy to operate.

Of course, the structural form in which the position of the connecting member 15 on the mounting member 11 along the second direction Y is adjustable is not limited to this. For example, a plurality of slots may be provided on the connecting member 15 along the second direction Y, and the locking member 152 may be a buckle (this embodiment is not shown in the figure). The connection between the connecting member 15 and the mounting member 11 and the adjustment of the position of the connecting member 15 in the second direction Y are achieved through the slots and the buckle.

In some examples, optionally, the anti-reversal member 13 of the present embodiment is configured so that the distance between the fourth end 132 and the connecting member 15 is adjustable in the first direction X, and/or the anti-overlapping member 14 is configured so that the distance between the sixth end 142 and the connecting member 15 is adjustable in the first direction X.

In the above technical solution, taking the example that the distance between the fourth end 132 of the anti-reverse member 13 and the connecting member 15 is adjustable, and the distance between the fourth end 132 of the anti-overlapping member 14 and the connecting member 15 is adjustable, the anti-reverse member 13 and the anti-overlapping member 14 can be easily adjusted to a suitable height protruding from the mounting member 11.

There are multiple ways to achieve that the distance between the fourth end 132 and the connecting member 15 is adjustable. The first way is to allow the anti-reversal member 13 to move relative to the mounting member 11 along the first direction X and lock it after the movement. The second way is to design the anti-reversal member 13 as a retractable structure. Similarly, the distance between the sixth end 142 and the connecting member 15 is adjustable in the first direction X.

In some examples, optionally, the anti-reversal member 13 of this embodiment is threadedly connected to the connecting member 15 , and the anti-stacking member 14 is threadedly connected to the connecting member 15 .

That is, this embodiment adopts the first method mentioned above, so that the anti-reversal component 13 can be moved along the first direction X relative to the mounting component 11 as a whole, and is locked after moving. Similarly, the anti-overlapping component 14 can be moved along the first direction X relative to the mounting component 11 as a whole, and is locked after moving.

By threading the anti-reversal member 13 and the anti-stack member 14 to the connecting member 15 respectively, the relative positions of the fourth end 132 and the sixth end 142 to the mounting member 11 can be finely adjusted, thereby improving the accuracy of the limiting of the two and the adapter.
