If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

The cell carrying module provided by the utility model comprises a workbench and a carrying unit, wherein the carrying unit comprises carrying strips 210, the carrying strips 210 are used for carrying cells, the carrying strips 210 are arranged at intervals, the carrying strips 210 can move between the upstream of the workbench and/or the carrying strips 210 can move between the workbench and the downstream of the workbench, the carrying strips 210 can ascend or descend relative to the workbench, and the workbench is provided with an avoidance area matched with the carrying strips 210.

Traditional cell loading and unloading are generally realized through grabbing of a manipulator, and the manipulator needs to clamp a cell to transfer the cell from one station to another station. Because the battery cell which is just wound is not completely shaped, the clamping force of the manipulator easily deforms the battery cell, so that the battery cell is damaged.

According to the battery cell carrying module provided by the utility model, the carrying unit can carry the battery cell to the workbench from the upstream and/or carry the battery cell to the downstream from the workbench, the battery cell does not need to be grabbed or clamped in the carrying process, and the damage of the carrying process to the battery cell can be reduced.

It can be understood that the cell handling module can be used in cooperation with the pre-pressing module 900, and at this time, the workbench serves as a carrying platform for pre-pressing the cell, and the cell handling module can also be used in other steps of the cell manufacturing process.

Particularly, the carrying unit carries the battery cell in a bearing mode, and the carrying unit can be used for feeding the battery cell to the workbench and/or discharging the battery cell from the workbench. Taking the example that the carrying unit is used for feeding the battery cells to the workbench, the carrying bar 210 waits at a preparation position connected with the upstream of the workbench, when the battery cells are conveyed to the upper side of the carrying bar 210 through a conveyer belt, a conveying roller or other conveying structures, the carrying bar 210 is lifted to lift the battery cells, then the carrying bar 210 moves to the upper side of the avoidance area, and the carrying bar 210 is lowered to enable the height of the carrying bar 210 to be lower than the upper surface of the workbench or to be flush with the upper surface of the workbench, so that the battery cells are transferred from the carrying bar 210 to the workbench. Similarly, when the carrying unit is used for blanking the battery cell from the workbench, the carrying bar 210 rises on the workbench to receive the material, and the carrying bar 210 descends on the downstream of the workbench to discharge the material, so that the blanking process through supporting is realized.

For convenience of description and illustration of the drawings, a direction of the lifting motion of the carrying bar 210 is defined as a first direction, which is indicated by an X-axis in the drawings, and a direction of the movement of the carrying bar 210 between upstream and downstream is defined as a second direction, which is indicated by a Y-axis in the drawings.

When the carrying unit can be used for feeding the battery cell to the workbench and discharging the battery cell from the workbench, the feeding action and the discharging action of the carrying bar 210 can be performed in parallel so as to accelerate the carrying speed of the battery cell. In some embodiments, the carrier strip 210 includes a first zone 211 and a second zone 212, the first zone 211 being movable between upstream of the table and the table, and the second zone being movable between the table and downstream of the table. At this time, referring to fig. 3, the carrier strip 210 operates as follows. When the first zone 211 is in a ready position in engagement with the upstream, the second zone 212 is in an avoidance zone. When the handling bar 210 is raised in a first direction, the first zone 211 captures cells upstream and the second zone captures cells on the table. Movement of carrier strip 210 in the second direction moves first region 211 from upstream to the work station and second region 212 from the work station to downstream. The carrier bar 210 is lowered in a first direction to transfer the cells in the first zone 211 to the table and the cells in the second zone 212 to the downstream, completing a feed and a discharge. The carry bar 210 is then reset to resume the above actions.

The movement of the carrying strip 210 can be implemented by different embodiments, for example, in some embodiments, the carrying unit includes a sliding table 220 and a guide rail 230, the guide rail 230 is arranged along the carrying direction of the battery cell, the sliding table 220 is mounted on the guide rail 230, a first driver 240 is mounted on the sliding table 220, the carrying strip 210 is mounted on the first driver 240, and the first driver 240 can drive the carrying strip 210 to approach or depart from the sliding table 220 along the first direction. The use of the guide rail 230 can improve the smoothness and accuracy of movement of the slide table 220. The first actuator 240 may employ an air cylinder, an electric cylinder, or the like.

The slide table 220 and the guide rail 230 can be installed in the avoidance area, thereby making the structure of the cell handling module compact. Referring to fig. 3, in some embodiments, the workbench includes a plurality of fixing bases 110, each fixing base 110 is spaced apart, an avoidance area is formed between adjacent fixing bases 110, and the guide rail 230 is installed in the avoidance area. The workstation adopts the split type design of a plurality of fixing base 110 combinations, and single fixing base 110's volume is less, helps reducing the processing degree of difficulty and the processing cost of workstation.

In some embodiments, the carrying unit includes a connection block 250 and a second driver 260, the connection block 250 connects the respective slide tables 220, the second driver 260 connects the connection block 250, and the second driver 260 can drive the slide tables 220 to move along the second direction. The connection block 250 enables one second driver 260 to simultaneously drive the plurality of sliding tables 220 to move synchronously, so that the structure of the carrying unit is more compact and simple.

It is understood that the embodiment of fig. 3 shows an embodiment in which the second direction of the conveyor bar 210 is the same as the upstream incoming material direction and the downstream outgoing material direction, and in other embodiments, the second direction may be different from the upstream incoming material direction and the downstream outgoing material direction.

In some embodiments, the cell handling module includes a buffer 270, and the buffer 270 is used for buffering the handling unit. For example, referring to fig. 3, the buffer 270 is located at the end of the moving path of the sliding table 220, and the buffer 270 is provided to prevent the sliding table 220 from rigid collision. Of course, buffer 270 may also be located at the end of the path of travel of the carry bar 210.

The butt joint line is used for butt joint between the battery cell carrying module and the previous station or the next station. Referring to fig. 1, the conveyor belts 310 are offset from the carrier strips 210 so that the carrier strips 210 can extend into the interface and the carrier strips 210 can be raised or lowered from between the spaces of adjacent conveyor belts 310 to retrieve or drop cells.

In some embodiments, the docking line includes a support plate 320, the support plate 320 is used for supporting the conveyor belt 310, and the support plate 320 is provided with a notch adapted to the carrying strip 210.
