[0028] Reference Figures 1 to 3 According to an embodiment of the present invention, the battery shell stacking and access device includes a stacking box 100 and a pressing module 200. The stacking box 100 is provided with a stacking cavity 100a, and the stacking cavity 100a is used to stack multiple battery shells 500 along a first direction. The stacking box 100 is provided with a first opening 100b communicating with the stacking cavity 100a at one end in the first direction. The stacking box 100 is provided with a side surface adjacent to the first opening 100b that is connected to the stacking cavity 100a. The second opening 100c is connected, and the second opening 100c is used for storing the battery shell 500 in the stacking cavity 100a; the pressing module 200 is arranged corresponding to the first opening 100b, and the pressing module 200 is used to press the battery shell 500 in the stacking cavity 100a along the first direction; wherein, the end of the stacking cavity 100a away from the first opening 100b is connected to the removal port 100d, and the removal port 100d is used for taking the battery shell 500 out of the stacking cavity 100a.

[0029] The battery shell stacking and retrieval device provided by the present invention can store and press multiple battery shells 500 in a stacked state, avoiding the situation where multiple battery shells 500 collide with each other during turnover and cause damage to the battery shells 500, and is conducive to supplying battery shells 500 to the next process to improve work efficiency.

[0030] Specifically, when the battery shell stacking and retrieval device provided by the present invention stores the battery shell 500, the battery shell 500 can be placed in the stacking cavity 100a from the second opening 100c and stacked neatly. After the battery shell 500 is stored, the pressing module 200 presses the stacked battery shells 500 in the stacking cavity 100a from the first opening 100b to prevent the stacked battery shells 500 from collapsing and becoming scattered during the turnover process. When the battery shell stacking and retrieval device supplies the battery shell 500 to the equipment of the next process, the equipment of the next process can take out the battery shell 500 in the stacking cavity 100a from the pickup port 100d. Among them, the first opening 100b of the stacking box 100 can be placed upward so that the pickup port 100d is located at the lower end of the stacking cavity 100a. At this time, the above-mentioned first direction is along the up and down direction. Therefore, each time the equipment of the next process takes out a battery shell 500 from the pickup port 100d, the remaining battery shells 500 in the stacking cavity 100a can be gradually moved to the pickup port 100d under the action of gravity, and then the equipment of the next process only needs to take the battery shell 500 from the pickup port 100d. Therefore, the equipment of the next process can load materials neatly and orderly and the loading position is fixed, eliminating complicated loading operations and improving work efficiency.

[0031] Of course, it is conceivable that, in other embodiments, the stroke of the pressing module 200 can be increased so that the pressing block 220 of the pressing module 200 can be moved to the pickup port 100d. Thus, the pressing module 200 can be used to push the battery housing 500 in the stacking cavity 100a toward the pickup port 100d, so that the battery housing 500 in the stacking cavity 100a can be gradually moved to the pickup port 100d. At this time, the first opening 100b of the stacking box 100 does not need to be placed upward.

[0032] Reference Figure 2 and Figure 3According to some embodiments of the present invention, the battery casing stacking and retrieval device further includes a blocking cover 300, which is detachably or movably mounted on the stacking box 100. The blocking cover 300 has a first state and a second state. When the blocking cover 300 is in the first state, the blocking cover 300 blocks a portion of the second opening 100c and exposes an end of the second opening 100c away from the first opening 100b, so that the end of the second opening 100c away from the first opening 100b forms a retrieval port 100d. When the blocking cover 300 is in the second state, the blocking cover 300 avoids the second opening 100c. With the above arrangement, the take-out opening 100d is formed by the blocking cover 300 that blocks the second opening 100c and the side wall of the second opening 100c away from the first opening 100b. There is no need to open the take-out opening 100d at other positions of the stacking box 100 other than the second opening 100c. Therefore, when the battery shell stacking and taking device stores the battery shell 500, the blocking cover 300 is placed in the second state to open the second opening 100c. At this time, multiple battery shells 500 can be stacked in sequence in the stacking cavity 100a from the second opening 100c to complete the battery shell 500 stacking. After storage, the blocking cover 300 is placed in the first state so that the second opening 100c is blocked by the blocking cover 300 except for the pickup port 100d. When the battery shell stacking and retrieval device supplies the battery shell 500 to the equipment of the next process, the equipment of the next process can take the battery shell 500 from the pickup port 100d, and the battery shell 500 in the stacking cavity 100a that is not at the pickup port 100d is blocked by the blocking cover 300 and cannot leave the stacking cavity 100a. In this way, the equipment of the next process can take the battery shell 500 one by one from the battery shell stacking and retrieval device.

[0033] During the specific implementation process, the blocking cover 300 can be detachably installed on the stacking box 100 by means of bolts or snaps. By installing the blocking cover 300 on the stacking box 100 and covering the second opening 100c, the blocking cover 300 can be placed in the first state. By removing the blocking cover 300 from the stacking box 100, the blocking cover 300 can be placed in the second state.

[0034] In other embodiments, the blocking cover 300 can also be rotatably installed or slidably installed on the stacking box 100. By rotating or sliding the blocking cover 300 to a position covering the second opening 100c, the blocking cover 300 can be placed in the first state. By rotating or sliding the blocking cover 300 to avoid the second opening 100c, the blocking cover 300 can be placed in the second state.

[0035] Reference Figure 1 、 Figure 2 and Figure 4According to some embodiments of the present invention, the stacking box 100 includes a first side panel 110, two second side panels 120, and a supporting structure 130. The two second side panels 120 are spaced apart along a second direction perpendicular to the first direction on one side of the first side panel 110. The supporting structure 130 is located inside the two second side panels 120 and connected to one end of the second side panels 120. The supporting structure 130 is used to support the battery housing 500. The stacking cavity 100a is formed by enclosing the first side panel 110, the two second side panels 120, and the supporting structure 130. The first opening 100b Located between the ends of the two second side plates 120 away from the supporting structure 130, the second opening 100c is located between the ends of the two second side plates 120 away from the first side plate 110. Therefore, in the process of storing the battery shell 500 in the battery shell stacking and retrieval device, multiple battery shells 500 are stacked on the supporting structure 130 in sequence. After the multiple battery shells 500 are stacked between the supporting structure 130, the two second side plates 120 and the first side plate 110 can be used to limit the position of the battery shell 500 to prevent the stacked multiple battery shells 500 from tilting.

[0036] It should be noted that the first direction mentioned above can refer to Figure 1 The up and down directions shown above can be referred to Figure 1 In the left-right direction shown, the first opening 100b is located at the upper end of the stacking cavity 100a, and the second opening 100c is located at the front end of the stacking cavity 100a.

[0037] Reference Figure 4 According to some embodiments of the present invention, the stacking box 100 is provided with a spacing adjustment device 170, which is used to slide and adjust the distance between the two second side panels 120. Through the above arrangement, the distance between the two second side panels 120 can be adjusted according to the size of the battery shells 500 of different models in the second direction, so that the size of the stacking chamber 100a in the second direction can adapt to battery shells 500 of different sizes. Among them, when the distance between the two second side panels 120 is adjusted, the width of the second opening 100c is also adjusted at the same time. In addition, since the pickup port 100d is formed by the end of the second opening 100c away from the first opening 100b, the size of the pickup port 100d is also adjusted synchronously, thereby meeting the needs of the stacking chamber 100a for storing battery shells 500 of different models and sizes and the need of the pickup port 100d for discharging battery shells 500 of different models and sizes.

[0038] Reference Figure 1 and Figure 4According to some embodiments of the present invention, the pressing module 200 includes an elastic driving member 210 and a pressure block 220. The pressure block 220 can be slidably installed on the stacking box 100. The elastic driving member 210 is arranged between the pressure block 220 and the stacking box 100. The elastic driving member 210 is used to drive the pressure block 220 to slide from the first opening 100b along the first direction into the stacking cavity 100a. A locking device 400 is provided between the pressure block 220 and the stacking box 100. When the pressure block 220 is away from the pickup port 100d, the locking device 400 can lock or unlock the position of the pressure block 220. Through the above arrangement, when stacking and storing multiple battery shells 500 in the stacking chamber 100a, the staff can pull the pressing block 220 to a position away from the pickup port 100d and lock the pressing block 220 through the locking device 400 to prevent the pressing block 220 from affecting the storage of the battery shells 500. After the storage of the battery shells 500 is completed, the locking device 400 contacts and locks the pressing block 220, so that the pressing block 220 is driven by the elastic driving member 210 to press and fix the battery shells 500 stacked in the stacking chamber 100a; when the battery shell stacking and taking device supplies the battery shells 500 to the equipment of the next process, as the equipment of the next process takes the battery shells 500 from the pickup port 100d, the pressing block 220 can synchronously push the remaining battery shells 500 in the stacking chamber 100a toward the pickup port 100d under the action of the elastic driving member 210.

[0039] Reference Figure 1 and Figure 4 According to some embodiments of the present invention, the stacking box 100 includes a top mounting plate 140, which is disposed opposite the first opening 100b. The pressing block 220 is connected to a guide rod 230, which is slidably disposed through the top mounting plate 140. The elastic driving member 210 is disposed between the pressing block 220 and the top mounting plate 140. Thus, the pressing block 220 can be slidably mounted on the stacking box 100. The engagement between the guide rod 230 and the top mounting plate 140 ensures smooth sliding of the pressing block 220. With the above arrangement, the pressing module 200 has a simple structure and is easy to assemble.

[0040] Reference Figure 3 According to some embodiments of the present invention, the stacking box 100 defines a third mounting hole 161, and the locking device 400 includes a locking bolt threaded into the third mounting hole 161. When the pressing block 220 is moved to the side of the third mounting hole 161 away from the access port 100d, the locking bolt is rotated. One end of the locking bolt can be extended or retracted to block or avoid the pressing block 220, thereby locking or unlocking the pressing block 220. This arrangement provides a simple structure for the locking device 400 and facilitates operation.

[0041] It is conceivable that the above-mentioned locking device 400 can also be set up in other ways. For example, the locking device 400 may include a locking rod and a return spring. The locking rod can be slidably installed in the third mounting hole 161. Then, when the pressure block 220 moves to the side of the third mounting hole 161 away from the pickup port 100d, the return spring drives the locking rod to extend between the pressure block 220 and the first opening 100b, thereby limiting the movement of the locking rod toward the first opening 100b. When it is necessary to release the restriction on the pressure block 220, the staff can pull the locking rod to retract the locking rod into the third mounting hole 161 to avoid the pressure block 220.

[0042] It is conceivable that the above-mentioned pressing module 200 may also be arranged in other ways. For example, the above-mentioned elastic driving member 210 may be replaced by a linear motor or a telescopic cylinder.

[0043] During the production process of soft-pack batteries, the battery shell 500 formed after stamping and cutting usually has a shape with both ends inclined relative to the middle. In order to better support the multiple battery shells 500 stacked together, according to some embodiments of the present invention, the supporting structure 130 includes two first supporting rods 131 extending along the second direction and two second supporting rods 132 extending along the second direction. The first supporting rods 131 and the second supporting rods 132 are installed on the second side plate 120. The two first supporting rods 131 are close to the first side plate 110 and are arranged at intervals in a direction inclined to the first direction. The two second supporting rods 132 are close to the second opening 100c and are arranged at intervals in a direction inclined to the first direction. The two first supporting rods 131 and the two second supporting rods 132 are distributed in a trapezoidal shape. Therefore, the second supporting rod 132 and the first supporting rod 131 located in the middle support the middle part of the battery shell 500, the two first supporting rods 131 cooperate with each other to support one inclined end of the battery shell 500, and the two second supporting rods 132 cooperate with each other to support the other inclined end of the battery shell 500, thereby better supporting multiple battery shells 500 stacked together.

[0044] Reference Figure 1 、 Figure 3 and Figure 4According to some embodiments of the present invention, a first adjustment structure 121 and a second adjustment structure 122 are provided on the second side plate 120. The first adjustment structure 121 is used to adjust the installation position of the two first supporting rods 131, and the second adjustment structure 122 is used to adjust the installation position of the two second supporting rods 132. Thus, by adjusting the installation position of the two first supporting rods 131 through the first adjustment structure 121, the inclination of the arrangement direction of the two first supporting rods 131 relative to the first direction is adjusted. By adjusting the installation position of the two second supporting rods 132 through the second adjustment structure 122, the inclination of the arrangement direction of the two second supporting rods 132 relative to the first direction is adjusted. It is even possible to adjust the distance between the first supporting rods 131 and the second supporting rods 132. In this way, the supporting structure 130 can be adapted to support different models of battery casings 500 having different inclinations of the ends relative to the middle.

[0045] Reference Figure 1 、 Figure 3 and Figure 4 Specifically, in some embodiments, the first adjustment structure 121 includes at least two first hole groups 1211 provided on the second side plate 120, the first hole groups 1211 including a plurality of first mounting holes 12111 spaced apart along a first direction, and the first supporting rod 131 can be inserted into any of the first mounting holes 12111. The second adjustment structure 122 includes at least two second hole groups 1221 provided on the second side plate 120, the second hole groups 1221 including a plurality of second mounting holes 12211 spaced apart along the first direction, and the second supporting rod 132 can be inserted into any of the second mounting holes 12211. Thus, by inserting the first supporting rod 131 into different first mounting holes 12111, the installation position of the first supporting rod 131 can be adjusted, and by inserting the second supporting rod 132 into different second mounting holes 12211, the installation position of the second supporting rod 132 can be adjusted.

[0046] It is conceivable that in other embodiments, the above-mentioned first adjustment structure 121 and the second adjustment structure 122 may also be arranged in other ways. For example, the first adjustment structure 121 includes at least two first strip holes arranged on the second side plate 120, the two adjacent first strip holes are arranged at intervals, and each first strip hole is inclined relative to the first direction, one end of each first supporting rod 131 can be slidably installed in any one of the first strip holes and locked in the installation position by tightening the bolt, thereby realizing the adjustment of the installation position of the first supporting rod 131; the second adjustment structure 122 includes at least two second strip holes arranged on the second side plate 120, the two adjacent second strip holes are arranged at intervals, and each second strip hole is inclined relative to the first direction, one end of each second supporting rod 132 can be slidably installed in any one of the second strip holes and locked in the installation position by tightening the bolt, thereby realizing the adjustment of the installation position of the second supporting rod 132.

[0047] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, the stacking box 100 includes a seat plate 150, an end of the first side plate 110 facing away from the first opening 100b is mounted on the seat plate 150, and an end of the two second side plates 120 facing away from the first opening 100b is slidably mounted on the seat plate 150. Thus, the battery casing stacking and access device can be placed on the ground, a workbench or other flat surface through the seat plate 150. At this time, the first direction is along the up-down direction, the first opening 100b faces upward, and the second opening 100c faces the horizontal side.

Through the setting of the pad 160, the friction damage to the battery housing 500 in the stacking cavity 100a during the movement toward the pickup port 100d is reduced.

One end of the adjustment bolt 171 passes through the adjustment hole 151 and is screwed to the second side plate 120. The other end of the adjustment bolt 171 is located on the side of the adjustment hole 151 facing away from the second side plate 120 and abuts against the sidewall of the adjustment hole 151. Therefore, when the adjustment bolt 171 is loosened, the second side plate 120 can slide along the adjustment hole 151 to adjust its position. The adjustment bolt 171 is then tightened to lock the position of the second side plate 120, thereby achieving adjustment of the spacing between the two second side plates 120. Through the above configuration, the spacing adjustment device 170 has a simple structure, is easy to install, and is low in cost.

[0050] Of course, it is conceivable that in other embodiments, the spacing adjustment device 170 can also be set to an automatic adjustment form through electric drive or pneumatic drive. Specifically, the second side panel 120 is slidably installed on the first side panel 110 or the seat panel through a guide rail structure. The spacing adjustment device 170 includes an electric drive device or a cylinder, which is transmission-connected to the second side panel 120. The second side panel 120 is driven to slide by the electric drive device or the cylinder, thereby realizing the spacing adjustment between the two second side panels 120.
