For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0044] In the first aspect of the present application, as Figures 1 to 11 shown, there is provided a high-efficiency transfer and loading workstation for a battery cell aluminum shell, including: a transfer slide table 100 for transporting the aluminum shell module to the transfer station; wherein, the aluminum shell module includes a mother frame, and a plurality of sub-frames in a standing posture are arranged in the mother frame, and an aluminum shell array is arranged in each sub-frame; a robotic arm 200, including a fixture mounting seat 1 at the end, and a first fixture 2 and a second fixture 3 connected to the fixture mounting seat 1; the first fixture 2 is used to clamp the sub-frame from the mother frame and place it in a standing posture on the flipping device; the second fixture 3 is used to clamp the aluminum shell array from the sub-frame and place it on the loading station; a flipping device 300, including a fixed frame 4, a flipping frame 5, and a flipping driving device 6, the flipping frame 5 is rotatably connected to the fixed frame 4, and the flipping driving device 6 is connected to the fixed frame 4 for driving the flipping frame 5 to rotate; the flipping frame 5 is docked with the sub-frame in a standing posture, and then flipped 90 degrees to make the sub-frame in a horizontal posture, so as to facilitate the robotic arm to pick up the material.

[0045] Specifically, the transfer slide 100 transports the aluminum shell module equipped with the mother frame, sub-frame, and battery cell aluminum shell to the transfer station. The robotic arm 200 uses the first fixture 2 at its end to pick up the sub-frame from the mother frame in a side-standing posture and places it on the flipping device 300 in a side-standing posture. Subsequently, the flipping device 300 docks with the sub-frame and flips it 90 degrees to make the sub-frame in a horizontal posture, facilitating the second fixture 3 of the robotic arm 200 to pick up the battery cell aluminum shell from the sub-frame and place it on the loading station. The robotic arm 200 needs to pick up the aluminum shell array from the sub-frame in a horizontal posture to ensure the stability of the picking process.

[0046] The robotic arm 200 picks up the sub-frame from the mother frame in a side-standing posture and then directly places the sub-frame on the flipping rack 5 in a side-standing posture. The flipping drive device 6 drives the flipping rack 5 to easily achieve the flipping of the sub-frame, thus avoiding the complex movement of the robotic arm 200 to achieve the flipping of the sub-frame, reducing the operation difficulty, and improving the transfer efficiency.

[0047] Meanwhile, the two fixtures of the robotic arm 200 respectively realize the two functions of picking up the sub-frame from the mother frame and picking up the aluminum shell array from the sub-frame, with high integration, avoiding the setting of additional material picking devices, reducing the overall cost, and making the transfer and loading process of the battery cell aluminum shell more flexible and efficient.

[0048] In some embodiments, as Figures 2 to 4 shown, the first fixture 2 includes a first clamping drive device 2.1. The first clamping drive device 2.1 is connected to the fixture mounting seat 1 through a first mounting plate. The two movable ends of the first clamping drive device 2.1 are respectively connected to a first clamping jaw and a second clamping jaw. Both the first clamping jaw and the second clamping jaw include positioning claws 2.2. The first clamping drive device 2.1 drives the two positioning claws 2.2 to approach each other to clamp the sub-frame in the length direction thereof; both the first clamping jaw and the second clamping jaw further include clamping claws 2.3. The positioning claws 2.2 are connected to a second clamping drive device 2.4 for driving the clamping claws 2.3 to approach the positioning claws 2.2 to clamp the sub-frame in the width direction thereof.

[0049] Specifically, when the first clamping drive device 2.1 is activated, it drives the two positioning claws to approach each other, thereby clamping the sub-frame in the length direction thereof; in addition, each clamping jaw further has a clamping claw 2.3. The positioning claws 2.2 are connected to the clamping claws 2.3 through the second clamping drive device 2.4. When the second clamping drive device 2.4 is activated, it drives the clamping claws 2.3 to approach the positioning claws 2.2 to further clamp the sub-frame in the width direction thereof. Through clamping in two directions, the clamping stability of the sub-frame during transfer can be ensured. Secondly, this fixture design can accurately pick up and place sub-frames of different sizes and models, improving the flexibility and adaptability of the robotic arm 200.

[0050] In some embodiments, as Figures 2 to 4 shown, the second fixture 3 includes a second mounting plate 3.1 fixedly connected to the fixture mounting seat 1. A plurality of suction nozzles 3.2 are arranged on the second mounting plate 3.1 in a rectangular array for sucking the corresponding battery cell aluminum cases in the sub-frame, and every two of the suction nozzles 3.2 correspondingly suck one of the battery cell aluminum cases.

[0051] Specifically, through the suction nozzles arranged in a rectangular array, multiple battery cell aluminum cases can be sucked at one time, improving the working efficiency. Secondly, the design that every two suction nozzles correspondingly suck one battery cell aluminum case enhances the stability of suction and avoids the dropping or damage of the battery cell aluminum cases during the suction or transfer process.

[0052] In some embodiments, as Figures 5 to 9 shown, the turnover frame 5 includes side support plates 5.1, a bottom support plate 5.2 and two side limit plates 5.3. The side support plates 5.1 and the side limit plates 5.3 are respectively connected to the peripheral side of the bottom support plate 5.2. The outer sides of the two side limit plates 5.3 are respectively connected to the fixed frame 4 through rotating shafts; when the turnover frame 5 is in a side-standing posture, the side support plates 5.1 are horizontal for supporting the sub-frame, and when the turnover frame 5 is in a horizontal posture, the bottom support plate 5.2 is horizontal for supporting the sub-frame.

[0053] Specifically, the outer sides of the two side limit plates 5.3 are respectively connected to the fixed frame through rotating shafts, so that the turnover frame 5 can rotate freely on the fixed frame 4. When the turnover frame 5 is in a side-standing posture, the side support plates 5.1 remain in a horizontal state to support the sub-frame, and when the turnover frame 5 is turned to a horizontal posture, the bottom support plate 5.2 becomes horizontal and also supports the sub-frame. The turnover frame 5 can be easily switched between the two postures. On the one hand, it enables the robotic arm 200 to more easily pick up the battery cell aluminum cases from the sub-frame. On the other hand, the robotic arm 200 picks up the sub-frame from the mother frame in a side-standing posture and then directly places the sub-frame on the turnover frame 5 in a side-standing posture. The turnover driving device 6 drives the turnover frame 5 to easily realize the turnover of the sub-frame, thus avoiding the complex movement of the robotic arm 200 to realize the turnover of the sub-frame, reducing the operation difficulty and improving the transfer efficiency.

[0054] In some embodiments, as Figures 5 to 9As shown in the figure, the flipping device 300 includes a number of locking components 7 provided outside the side limiting plate 5.3; the locking component 7 includes a third mounting plate 7.1, a first linear driving device 7.2, a pull rod 7.3, and a locking plate 7.4. The third mounting plate 7.1 is fixedly connected to the side limiting plate 5.3. The fulcrum portion of the locking plate 7.4 is rotatably connected to the third mounting plate 7.1. One end of the locking plate 7.4 is connected to the pull rod 7.3, the other end of the pull rod 7.3 is connected to the first linear driving device 7.2, and the other end of the first linear driving device 7.2 is rotatably connected to the third mounting plate 7.1. When the first linear driving device 7.2 extends, it drives the linear displacement of the pull rod 7.3 and pushes the locking plate 7.4 to rotate, so that the other end of the locking plate 7.4 presses against the edge of the sub-frame.

[0055] Specifically, the fulcrum portion of the locking plate 7.4 is rotatably connected to the third mounting plate 7.1, so that the locking plate 7.4 can freely rotate within a certain range. One end of the locking plate 7.4 is connected to the pull rod 7.3, and the other end of the pull rod 7.3 is connected to the first linear driving device 7.2. When the first linear driving device 7.2 extends, it drives the linear displacement of the pull rod 7.3, and then pushes the locking plate 7.4 to rotate, so that the other end of the locking plate 7.4 presses against the edge of the sub-frame. Through the locking mechanism of the locking component 7, it can be ensured that the sub-frame will not shake or fall during the flipping process.

[0056] In some embodiments, as Figures 5 to 9 shown, the flipping device 300 includes an automatic cover opening device, and the automatic cover opening device includes a top cover device 8 and a cover moving device 9. The top cover device 8 includes a second linear driving device 8.1, a third linear driving device 8.2, and a top block 8.3. One end of the third linear driving device 8.2 is connected to the fixed frame 4, and the other end is connected to the second linear driving device 8.1. The second linear driving device 8.1 is connected to the top block 8.3. The third linear driving device 8.2 is used to push the second linear driving device 8.1 to the edge of the cover plate of the sub-frame, and the second linear driving device 8.1 jacks up the cover plate by a predetermined angle through the top block 8.3, so as to facilitate the cover opening operation of the cover moving device 9.

[0057] Specifically, the automatic cover opening device realizes the automation of the cover opening operation without manual intervention, thereby improving work efficiency and safety. By controlling the second linear driving device 8.1 to push the top block 8.3, it can be ensured that the cover plate is accurately jacked up. By controlling the third linear driving device 8.2, the second linear driving device 8.1 can be made to approach the edge of the sub-frame, facilitating the subsequent jacking operation, and the second linear driving device 8.1 can also be made to move away from the edge of the sub-frame, thereby avoiding interfering with the rotation of the sub-frame. Generally speaking, the automatic cover opening device has the advantages of flexibility, high efficiency, and accuracy.

[0058] In some embodiments, as Figure 7 shown, the cover moving device 9 includes a rotary driving device 9.1, a rotary rod 9.2, a fork 9.3 and a fourth linear driving device 9.4. The fourth linear driving device 9.4 is connected to the fixed frame 4 and is also connected to the rotary driving device 9.1 for advancing it to the edge of the cover plate. The rotary driving device 9.1 is connected to the rotary rod 9.2 for driving it to rotate. The end of the rotary rod 9.2 is connected to the fork 9.3 for inserting into the edge of the cover plate to drive the cover plate to open a predetermined opening degree.

[0059] Specifically, the fourth linear driving device 9.4 is used to advance the rotary driving device 9.1 to the edge of the cover plate. The rotary driving device 9.1 drives the rotary rod 9.2 to rotate, and the end of the rotary rod 9.2 is connected to the fork 9.3. After the fork 9.3 is inserted into the edge of the cover plate, with the rotation of the rotary rod 9.2, the fork 9.3 will drive the cover plate to open a predetermined opening degree. The coordinated work of this device and the top cover device 8 realizes the automatic opening operation of the cover plate without manual effort, improves the work efficiency, and makes the whole automatic cover opening process smoother and more efficient.

[0060] In some embodiments, as Figures 10 to 11 shown, the transfer sliding table 100 includes a guide rail bracket 10, a transfer plate 11 and a positioning component. The transfer plate 11 is connected to the guide rail bracket 10 and is displaced relative to it for guiding. The positioning component is connected to the transfer plate 11 for positioning the aluminum shell module. The transfer plate 11 is provided with a plurality of longitudinally arranged and juxtaposed rollers 11.1. One end of each roller 11.1 is connected with a driven sprocket. A roller driving motor is arranged on the lower side of the transfer plate 11. The roller driving motor drives the rollers 11.1 to rotate through chain sprocket transmission so that the aluminum shell module is longitudinally displaced to abut against the longitudinal edge on the transfer plate 11.

[0061] Specifically, when the roller driving motor arranged on the lower side of the transfer plate 11 is started, it drives all the rollers 11.1 to rotate synchronously through chain sprocket transmission. In this way, the aluminum shell module placed on the rollers 11.1 will be longitudinally displaced to abut against the longitudinal edge on the transfer plate 11 under the rotation of the rollers, thereby realizing the precise positioning on one side of the mother frame.

[0062] In some embodiments, as Figures 10 to 11As shown in the figure, the positioning assembly includes a mother frame lateral positioning device, a sub-frame lateral positioning device, and a sub-frame longitudinal positioning device; the mother frame lateral positioning device includes two transverse push cylinders 12 fixedly arranged on one side of the transfer plate, and the transverse push cylinders 12 are used to laterally push the mother frame until it abuts against the lateral edge on the other side of the transfer plate 11, so as to realize the lateral positioning of the mother frame; the sub-frame lateral positioning device includes two clamping cylinders 13, which are respectively arranged on the lateral sides of the transfer plate 11, and are used to pass through the mother frame to perform lateral clamping positioning on the sub-frame; the sub-frame longitudinal positioning device includes a longitudinal push cylinder 14, and the longitudinal push cylinder 14 is connected to one side of the guide rail bracket 10 close to the longitudinal edge, and is used to pass through the mother frame to perform longitudinal pushing on the sub-frame, so as to realize the longitudinal positioning of the sub-frame.

[0063] Specifically, the mother frame lateral positioning device laterally pushes the mother frame through two transverse push cylinders 12 until it abuts against the lateral edge on the other side of the transfer plate 11, so as to realize the precise lateral positioning of the mother frame. The sub-frame lateral positioning device utilizes two clamping cylinders 13 which are respectively arranged on the lateral sides of the transfer plate 11, and the clamping cylinders 13 perform lateral clamping positioning on the sub-frame by passing through the gap of the mother frame, ensuring the stability of the sub-frame in the lateral direction. The sub-frame longitudinal positioning device longitudinally pushes the sub-frame through the longitudinal push cylinder 14 passing through the mother frame, so that it abuts against the longitudinal edge on the transfer plate 11, realizing the precise longitudinal positioning of the sub-frame.
