DETAILED DESCRIPTION

[0050] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0051] See also Figure 1-4 The embodiment of the present invention provides a small-piece support plate 10, wherein a front support bar 11 and a rear support bar 12 are respectively arranged at the front and rear ends of the support plate, and the front support bar 11 and the rear support bar 12 are both comb-tooth-shaped, and the front support bar 11 and the rear support bar 12 are shoulder-stacked, and an adsorption portion 13 is arranged between the front support bar 11 and the rear support bar 12, and a negative pressure adsorption hole 131 is arranged inside the adsorption portion 13 to connect with an external negative pressure system, and a long groove 121 for placing a welding strip is provided on the upper surface of the rear support bar 12, and the projection of the long groove 121 in the horizontal plane is located between two adjacent front support bars 11, so that after the front and rear shoulders of two adjacent small-piece support plates 10 are arranged close to each other, the welding strip thereon is located at the same welding position of the front and rear small pieces 200, and most preferably, it is located in the same straight line, that is, on the main grid line welding point on the back of the small piece.

[0052] There are at least two ways to set the length of the long slot 121. One is to set it through the surface of the rear support bar 12, and the other is to set it in a non-through manner.

[0053] The front support bar 11 and the rear support bar 12 are both comb-shaped, which is convenient for front and rear shoulder insertion to realize the connection of two adjacent sub-pieces 200. The upper surface of the front support bar 11 and the adsorption portion 13 together form a surface for supporting the sub-pieces 200, and the rear support bar 12 forms a groove for placing the welding strip.

[0054] Of course, this solution is the most preferred solution. The comb-shaped front support bar 11 and the rear support bar 12 are easy to plug in, so that the front small pieces 200 can be stacked in a string with the rear small pieces 200 through the welding strips, and the weight of the small piece support plate 10 is minimized. Other support plates that are respectively provided with a battery cell end and a welding strip end, and are provided with a battery cell end, a welding strip end and an adsorption part at the same time, are all variations of this solution.

[0055] See also Figure 4-6 and Figure 7 and Figure 8-10The present invention further proposes three mechanisms for stringing small pieces and combining them into a whole piece. The three mechanisms all include a translation unit 21, a side support plate 22, an upper mold pressing plate 23 and a small piece support plate 10. The small piece support plate 10 is arranged on the side support plate 22, and the side support plate 22 is arranged above the translation unit 21. The side support plate 22 has a surface supporting the upper mold pressing plate 23. The upper mold pressing plate 23 covers the small piece support plate 10 and is fixed on the small piece support plate by magnet adsorption, so as to limit the small pieces 200 and the welding strips 100 on the small piece support plate 10. The translation unit 21 drives the side support plate 22, the small piece support plate 10, the upper mold pressing plate 23, the small pieces and the welding strips to move back and forth in parallel.

[0056] Furthermore, the translation unit 21 includes a connecting plate 211, a translation drive 212, a guide rail 213, a slider 214, and a slider seat 215. The guide rail 213 is arranged along the length direction of the connecting plate 211, the translation drive 212 is arranged at the end of the connecting plate 211, and the output end of the translation drive 212 is transmission-connected to the slider 214. The slider 214 is arranged on the slider seat 215 and slidingly cooperates with the guide rail 213. The slider 214 and the slider seat 215 are arranged according to the number of battery cell slices.

[0057] The first type of cloth stringing mechanism for dividing small pieces 200 into a whole piece also includes a support 24, which is arranged in pairs at both ends of the slider seat 215 of the translation unit 21, and the support 24 has a surface supporting the side support plate 22; in the first embodiment, the support 24 can be an extension structure of the side support plate 22 or the slider seat 215, or it can be a separate independent structure, and the structure that can connect the translation unit 21 with the side support plate 22 can be sufficient.

[0058] The second type of mechanism for combining small pieces 200 and a whole piece of cloth string also includes a plurality of lifting units 25, which are arranged side by side on the translation unit 21 and driven by the translation unit 21 to move back and forth in parallel. The side support plate 22 is arranged on the lifting unit 25, and is driven by the lifting unit 25 to move up and down, thereby driving a plurality of small piece support plates 10 to move up and down.

[0059] Furthermore, the lifting unit 25 includes a lifting drive 251, a stand 252, a support plate 253, a small guide rail 254, and a small slider 255. The lifting drive 251 is fixedly arranged on the stand 252, the stand 252 is connected to the slider seat 215, the small slider 255 is installed on the stand 252 in cooperation with the small guide rail 254, the bottom end of the support plate 253 is coordinated with the output end of the lifting drive 251, the side of the support plate 253 is connected to the small slider 255, and the support plate 253 has a surface supporting the side support plate 22, so that the side support plate 22 and the small piece support plate 10 thereon carry the small pieces 200, the welding strip 100 and the upper mold plate 23 thereon to rise or fall.

[0060] The third type of mechanism for stringing together the small pieces 200 and the whole piece also includes a plurality of rotating units 26, which are arranged side by side on the translation unit 21 and driven by the translation unit 21 to move back and forth in parallel. The side support plate 22 is arranged on the rotating unit 26 and driven by the rotating unit 26 to rotate at a small angle, thereby driving the small piece support plate 10, the small pieces 200 and the welding strip 100 thereon to rotate.

[0061] Furthermore, the rotating unit 26 includes a fixed seat 261, a rotating drive 262, a capstan seat 263, a push rod 264, a first rotating shaft 265, a rotating block 266 and a second rotating shaft 267. The fixed seat 261 is fixedly connected to the slider seat 215 of the translation unit 21, the rotating drive 262 is fixedly installed on the fixed seat 261, the capstan seat 263 is connected to the output end of the rotating drive 262, one end of the push rod 264 is rotatably connected to the capstan seat 263, and the other end is rotatably connected to one end of the rotating block 266 through the first rotating shaft 265, the other end of the rotating block 266 is connected to the fixed seat 261 through the second rotating shaft 267, and the side support plate 22 is fixedly connected to the rotating block 266 so that the side support plate 22 can rotate a certain angle under the drive of the rotating drive 262.

[0062] Furthermore, the width of the upper mold plate 23 is adapted to the width of the front support bar 11 of the sub-piece support plate 10, so as to limit the coverage of the sub-pieces 200 and the welding strips 100 on the front support bar 11 without covering the rear support bar 12 and the welding strips 100 thereon.

[0063] Here, the width of the upper mold plate 23 is limited so as not to cover the rear support bar 12 and the welding strip thereon, and a position is reserved for the adjacent small-piece support plates 10 to be directly plugged in, lifted in, or rotated in.

[0064] See also Figure 11-15 16-20, the present invention also provides a method for dividing small pieces into whole pieces, comprising the following steps:

[0065] Separate the plurality of small-piece support plates 10 from each other, keeping them from touching each other;

[0066] Placing a plurality of sub-pieces 200 on a plurality of sub-piece support plates 10;

[0067] Alternatively, a plurality of sub-pieces are first placed on a plurality of sub-piece support plates, and then the plurality of sub-piece support plates are separated with the plurality of sub-pieces, so that the front and rear pieces do not contact each other;

[0068] A plurality of groups of welding strips 100 are placed on a plurality of sub-pieces 200, wherein the welding strips 100 are shaped into

[0069] The portion placed at the end of the rear support bar 12 is lower than the portion placed at the end of the front support bar 11;

[0070] Place a plurality of upper mold plates 23 on each of the small-piece support plates 10 and fix them by magnets;

[0071] The translation unit 21 moves to shorten the distance between adjacent sub-chip support plates 10 so that the welding strips 100 on the adjacent sub-chip support plates 10 are located below the sub-chips 200;

[0072] See also Figure 11-15 21-24, the present invention also proposes another method for dividing small pieces 200 into a whole piece of cloth string, comprising the following steps:

[0073] Separate the plurality of small-piece pallets 10 from each other, keeping them from touching each other;

[0074] Placing a plurality of sub-pieces 200 on a plurality of sub-piece support plates 10;

[0075] Alternatively, a plurality of sub-pieces are first placed on a plurality of sub-piece support plates, and then the plurality of sub-piece support plates are separated with the plurality of sub-pieces, so that the front and rear pieces do not contact each other;

[0076] Placing a plurality of welding strips 100 on a plurality of sub-pieces 200 accordingly;

[0077] Place a plurality of upper mold plates 23 on each of the small-piece support plates 10 and fix them by magnets;

[0078] Taking the small-piece support plate 10 at the front end as a reference, each small-piece support plate 10 at the rear end is lifted up to a corresponding height in sequence to form a step shape;

[0079] Alternatively, the small-piece support plates 10 at the rear end are used as a reference, and the small-piece support plates 10 at the front end are sequentially lowered to a corresponding height to form a step shape;

[0080] Shorten the distance between adjacent sub-chip support plates 10 so that the welding strips 100 on the adjacent sub-chip support plates 10 are located below the sub-chips 200;

[0081] Lower or lift each small-piece support plate 10 to keep the small-piece support plate level;

[0082] See also Figure 11-15 and Figure 25-28 The present invention also proposes a third method for dividing small pieces into a whole piece of cloth string, comprising the following steps:

[0083] Separate the plurality of small-piece pallets 10 from each other, keeping them from touching each other;

[0084] Placing a plurality of sub-pieces 200 on a plurality of sub-piece support plates 10;

[0085] Alternatively, a plurality of sub-pieces are first placed on a plurality of sub-piece support plates, and then the plurality of sub-piece support plates are separated with the plurality of sub-pieces, so that the front and rear pieces do not contact each other;

[0086] Placing a plurality of welding strips 100 on a plurality of sub-pieces 200 accordingly;

[0087] Place a plurality of upper mold plates 23 on each of the small-piece support plates 10 and fix them by magnets;

[0088] Rotate each sub-piece support plate 10 and the sub-pieces 200 and the welding strip 100 thereon in the same direction;

[0089] Shorten the distance between adjacent sub-chip support plates 10 so that the welding strips 100 on the adjacent sub-chip support plates 10 are located below the sub-chips 200;

[0090] The small-piece dividing pallet 10 is rotated in the reverse direction to keep the small-piece dividing pallet 10 horizontal; the small-piece dividing pallet 10 is the small-piece dividing pallet 10 described above.

[0091] Furthermore, when the distance between adjacent sub-piece pallets 10 is shortened, the distance between adjacent sub-pieces 200 is maintained at (-1.5 to 5) mm and / or (16 to 60) mm.

[0092] Further, several groups of welding strips 100 are placed on several sub-pieces 200 respectively, and one end of each welding strip 100 in each group of welding strips is placed on each main grid line on the front side of each sub-piece 200, and the other end is placed in the long groove 121 of the rear support bar 12 of each sub-piece pallet 10.

[0093] The arrangement of the long groove 121 of the rear support bar 12 can keep the welding strip in the long groove 121, and will not shake forward, backward, left or right. When the distance between adjacent sub-piece pallets 10 is shortened, since the sub-piece pallets 10 are hard components, the long groove 121 of the rear support bar 12 of two adjacent sub-piece pallets 10 is located between two adjacent front support bars 11, that is, the long groove 121 and the main grid line welding point on the back of the front sub-piece 200 overlap and face each other, so that through the constraint of the long groove 121, when the welding strip 100 in the long groove 121 is inserted into the front sub-piece 200, it is ensured that the welding strip 100 overlaps with the main grid line welding point on the back of the front sub-piece 200. This effect is not achieved by the solution without the long groove 121. If the long groove 121 is not provided, the welding strip will shake left and right. After contacting the back of the front sub-piece 200, it is also impossible to ensure that it overlaps with the main grid line welding point on the back, and the accuracy of stringing is very poor.

[0094] A specific implementation is:

[0095] S1: The translation unit 21 of the stringing mechanism moves to separate the small-piece support plates 10 arranged according to the number of battery cell pieces by a certain distance;

[0096] S2: placing each sub-piece 200 of the whole battery sheet that is split into n small pieces on each side support plate 22 of the stringing mechanism;

[0097] S3: synchronously arranging the prepared n groups of special-shaped welding strips 100 on each main grid line of each sub-piece 200;

[0098] S4: placing n upper mold plates 23 synchronously above the welding strips 100 of each sub-piece, that is, placing them on the side support plate 22;

[0099] S5: The translation drive 212 of the translation unit 21 is actuated to drive the slider seat 215 and the stand 24, the side support plate 22 and the sub-pieces, welding strips, and the upper mold plate 23 thereon to move a certain distance, so that the welding strips of each adjacent sub-piece are placed under the sub-piece behind; and the gap between each adjacent sub-piece and the welding strips thereon is made to be s, thus completing the arrangement of a small battery string.

[0100] Another specific implementation is:

[0101] S1: The translation unit 21 of the stringing mechanism moves to separate the small-piece support plates 10 arranged according to the number of battery cell pieces by a certain distance;

[0102] S2: placing the small pieces of the whole battery sheet that has been split into n small pieces on the side support plates 22 of the stringing mechanism;

[0103] S3: synchronously arranging the prepared n groups of welding strips on each main grid line of each sub-piece;
