[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the highly active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream and are often used in series-parallel battery packs.

[0003] During this process, lithium batteries need to be placed one by one into the bottom bracket. Due to the small installation gap between lithium batteries and the installation method of placing them in slots, in addition to manual operation, robotic arms and suction cup mechanisms can only be used to grab and place rows of lithium batteries as a whole. Frequent grabbing actions greatly reduce the installation efficiency.

[0010] As a further solution of the present invention, adjacent claws are angularly linked via mutually meshing meshing teeth.

[0011] As a further solution of the present invention: a vertical guide groove is concavely provided on the inner side of the bottom of the claw piece.

[0012] As a further solution of the present invention: a vertically protruding guide strip is provided on the outer side of the claw piece, and the corresponding position of the inner wall of the movable sleeve and the protruding structure limit the circumferential angle of the guide strip.

[0029] A lithium battery production and assembly device provided in this embodiment includes a dual-axis mobile platform 1, a support plate 2 for placing a mounting frame is fixed on the dual-axis mobile platform 1, a material discharge claw 3 connected to a feeding mechanism is provided above the dual-axis mobile platform 1, and the material discharge claw 3 includes a material channel 31, a driving motor 32, a push plate 33 and a guide claw 37. The material channel 31 is T-shaped, and one end is connected to a movable push plate 33 through a driving motor 32. The bottom of the end opposite to the movement direction of the push plate 33 is provided with a vertical guide claw 37, and the guide claw 37 is a funnel-shaped structure composed of circumferentially distributed movable sheet structures. The remaining end of the material channel 31 is connected to the feeding mechanism for feeding; By setting the unloading claw 3, lithium batteries can be continuously fed, and the push plate 33 can be used to continuously, quickly and accurately unload the materials. The claw-shaped guide claw 37 on the lower side of the material channel 31 can guide the fallen lithium batteries to the center while also slowing down the falling of the lithium batteries through the friction force of the inner wall of the guide claw 37 to facilitate installation.

[0030] The unloading claw 3 further includes a movable sleeve 36, and the guide claw 37 is nested in the movable sleeve 36 and slides axially along the movable sleeve 36. The movable sleeve 36 is driven by a driving screw 35 connected to the output end of a driving motor 32 fixed on the material channel 31, and is guided by a guide rod 34. By driving the screw rod 35 to drive the movable sleeve 36 and the guide claw 37 up and down, a single mounting hole of the lithium battery mounting frame is positioned, thereby improving the accuracy of lithium battery insertion.

[0031] Specifically, there is a protruding structure on the support plate 2 corresponding to the bottom groove structure of the lithium battery mounting frame, and a 1mm movable gap is left between the protruding structure and the bottom groove structure of the lithium battery mounting frame, thereby providing a small range of planar movement clearance for the lithium battery mounting frame while limiting the position, thereby achieving positioning.

[0032] Specifically, the guide claw 37 is composed of claw pieces 371 distributed circumferentially. The claw pieces 371 have a sheet structure that is wide at the top and narrow at the bottom. The claw pieces 371 are movably connected to each other, and under the action of gravity, the bottoms gather to form a funnel structure as a whole. The bottom surface of the claw piece 371 is an inclined structure, and the installation plate is guided and positioned by the contact between the inclined surface and the edge of the installation hole on the lithium battery installation plate.

[0033] Furthermore, adjacent claw pieces 371 are angularly linked through mutually meshing teeth 372, thereby ensuring the consistency of the angles of the claw pieces 371 and avoiding the angular deflection of the overall falling channel, so as to ensure that the lithium battery is always in the center during the falling process.

[0034] Furthermore, a vertical guide groove is concavely formed on the inner side of the bottom of the claw piece 371, so as to guide the lithium battery vertically during its falling process, prevent circumferential rotation during the falling process, and ensure the accuracy of its falling position.

[0035] Furthermore, there is a vertically protruding guide bar 373 on the outer side of the claw piece 371, and the corresponding inner wall of the movable sleeve 36 and the protruding structure limit the circumferential angle of the guide bar 373 to prevent the guide claw 37 from angular deflection in the movable sleeve 36, thereby improving stability and reducing the impact on the falling accuracy of the lithium battery.

[0036] Furthermore, the claw piece 371 is provided with a lifting wheel 374 which crosses the claw piece 371 , and the lifting wheel 374 is composed of a transmission wheel connected to an inner transmission wheel 3741 and an outer transmission wheel 3742 , which protrude from the inner and outer sides of the claw piece 371 respectively; Through the transmission setting of the inner transmission wheel 3741 and the outer transmission wheel 3742, when the inner lithium battery falls and contacts the inner transmission wheel 3741, the rotation of the inner transmission wheel 3741 can drive the outer transmission wheel 3742 to rotate, thereby lifting the guide claw 37. The resistance of the lifting of the guide claw 37 can slow down the falling speed of the lithium battery and play a damping and buffering role.

[0037] Furthermore, the outer transmission wheel 3742 is made of elastic soft rubber material, so that when the angle of the claw piece 371 changes, that is, when the distance between the claw piece 371 and the inner wall of the movable sleeve 36 changes, the outer transmission wheel 3742 can always fit the inner wall of the movable sleeve 36.

[0038] Furthermore, an arc-shaped convex edge protrudes above the inner transmission wheel 3741 on the inner side of the claw piece 371, thereby playing a buffering and guiding role for the falling lithium battery, reducing the vertical impact force when it contacts the inner transmission wheel 3741, and avoiding hard contact.

[0039] When implementing the technical solution recorded in this embodiment, the lithium battery mounting bracket is aligned with the structure of the support plate 2 and inserted into the mounting bracket. The lithium battery is continuously fed into the material channel 31 under the action of the feeding mechanism. The guide claw 37 moves downward along with the movable sleeve 36 under the action of the driving screw 35, and cooperates with the movement of the dual-axis mobile platform 1 to position the single mounting hole and move it upward to reset. Subsequently, the lithium battery at the front end of the material channel 31 falls into the guide claw 37 below under the action of the push plate 33, and falls into the positioned mounting hole along the guidance of the guide claw 37. During the falling process, it contacts the inner wall of the claw piece 371 and the inner transmission wheel 3741, and decelerates through the weight of the claw piece 371. Finally, it falls into the mounting hole, and the dual-axis mobile platform 1 moves to switch the mounting hole position.
