Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0033] As Figure 1As shown, the multi-channel pitch-changing device 100 of some embodiments of this application includes a conveying mechanism 110, a guiding mechanism 120, and a pitch-changing mechanism 130. The conveying mechanism 110 is used to convey battery cells; the guiding mechanism 120 includes a plurality of spaced-apart guiding components 121, which are disposed on the upper side of the conveying mechanism 110 and are used to guide the battery cells to travel along the conveying direction; the pitch-changing mechanism 130 is disposed downstream of the guiding mechanism 120, and includes a plurality of spaced-apart pitch-changing components 131, which correspond one-to-one with the guiding components 121. Each pitch-changing component 131 is used to receive the battery cell of the corresponding guiding component 121, and the pitch-changing component 131 can carry the corresponding battery cell to move in a direction perpendicular to its conveying direction to change the conveying distance of the battery cells.

[0034] The conveying mechanism 110 is used to convey battery cells along a first direction X. A guide assembly 121 is located on the upper side of the conveying mechanism 110 along the vertical direction Z. Each guide assembly 121 forms a conveying channel 122, which guides the battery cells to travel along the first direction X within the conveying channel 122. Multiple guide assemblies 121 are spaced apart along a second direction Y, and multiple pitch-changing assemblies 131 are also spaced apart along the second direction Y. The battery cells guided by each guide assembly 121 enter the corresponding pitch-changing assembly 131 along the first direction X. The pitch-changing assembly 131 moves along the second direction Y to carry the battery cells synchronously. The first direction X and the second direction Y are two mutually perpendicular horizontal directions.

[0035] The multi-channel pitch-changing device 100 of this application embodiment includes a conveying mechanism 110 and a pitch-changing mechanism 130. A row of battery cells conveyed by the conveying mechanism 110 travels along the conveying direction under the guidance of the guiding mechanism 120. The pitch-changing mechanism 130 is disposed downstream of the guiding mechanism 120. Each pitch-changing component 131 receives the corresponding battery cell and can move in a direction perpendicular to its conveying direction to adjust the spacing between the battery cells. Because the multi-channel pitch-changing device 100 of this application embodiment is provided with the pitch-changing mechanism 130, the pitch-changing function can be integrated during the conveying of battery cells, which not only reduces the footprint and shortens the production line length, but also reduces equipment costs.

[0036] like Figure 1 As shown, in some embodiments of this application, ten guide components 121 and ten pitch-changing components 131 are provided, that is, the multi-channel pitch-changing device 100 includes ten conveying channels 122, which can convey ten battery cells arranged side by side and realize pitch-changing processing of ten battery cells.

[0037] In other embodiments, the number of conveying channels 122 of the multi-channel pitch device 100 may also be six, eight, etc.

[0039] The multi-channel variable-pitch device 100 further includes a rack 140, the conveying drive is arranged on the rack 140, and the rollers 111 are rotatably mounted on the rack 140.

[0042] The length direction of the guide rods 1211 extends along the first direction X, and the guide mechanism 120 further includes a support frame 123 and a plurality of vertical rods 124. The support frame 123 is arranged on the rack 140, a part of the vertical rods 124 is located on the upper side of the conveying mechanism 110, the top of the vertical rods 124 is fixed to the support frame 123, and the bottom of the vertical rods 124 is connected with the guide rods 1211; another part of the vertical rods 124 is arranged on the rack 140 and extends from the gap between two adjacent rollers 111, and the top of the vertical rods 124 is connected with the guide rods 1211 to support the guide rods 1211.

[0043] Through this arrangement, the conveying channel 122 can be simply and reliably formed to guide the battery cell to move along the first direction X in the conveying channel 122.

[0044] As shown in FIG. 1, Figure 2 In some embodiments of the present application, the guide rods 1211 are provided with a plurality of spaced rollers 1212, which are used to guide the battery cell to move along the conveying direction.

[0045] The plurality of rollers 1212 are arranged along the first direction X on the guide rods 1211, and during the movement of the battery cell along the first direction X, the two side walls along the second direction Y are respectively matched with the rollers 1212 of the guide rods 1211 on the same side.

[0046] Through this arrangement, not only the battery cell can be guided to move along the first direction X, but also the wear on the surface of the battery cell can be reduced.

[0047] As shown in FIG. 1, Figure 3 ,Figure 7 and Figure 8 As shown, in some embodiments of this application, the pitch mechanism 130 includes a mounting plate 132, and the pitch assembly 131 includes a sliding plate 133, a pitch drive 134, and a clamping plate assembly 135.

The sliding plate 133 is disposed on the upper side of the mounting plate 132 and slides in cooperation with the mounting plate 132 in the second direction Y via the guide rail assembly 1331. The pitch-changing drive 134 is disposed on the lower side of the mounting plate 132 and drives the sliding plate 133 to move in the second direction Y via the transmission assembly 136.

[0049] For example, the variable pitch drive 134 is a motor, which can flexibly adjust the position of the sliding plate 133 to adapt to different pitch requirements; in other embodiments, the variable pitch drive 134 can also be a linear cylinder.

[0050] The clamping drive 1351 is disposed on the upper side of the sliding plate 133. A pair of clamping plates 1352 are disposed opposite each other along the second direction Y. The clamping drive 1351 is used to drive the pair of clamping plates 1352 to move closer to each other along the second direction Y to clamp the battery cell, and to move away from each other to release the battery cell or receive the battery cell.

[0051] For example, the clamping drive 1351 is a cylinder finger, and the two actuating ends of the cylinder finger are respectively connected to a clamping plate 1352. The cylinder finger opens to drive a pair of clamping plates 1352 away from each other, and the cylinder finger clamps to drive a pair of clamping plates 1352 closer to each other. In other embodiments, a pair of clamping plates 1352 can also be driven by a motor bidirectional lead screw nut mechanism.

[0052] With this configuration, the battery cells are clamped by the clamping drive 1351 and moved along the second direction Y by the variable pitch drive 134. This reduces the shaking and vibration of the battery cells during the adjustment of the spacing between them.

[0057] In other embodiments, the variable distance drive 134 can also drive the sliding plate 133 to move through the gear and rack.
