[0044] Therefore, the utility model proposes a spline manipulator.

[0045] In the embodiment of the present utility model, refer to Figure 1 and Figure 2 The spline manipulator includes a main bracket 10, a rotating structure 20, a lifting structure 30 and a stacking piece 40. The main bracket 10 has a first mounting position 10a and a second mounting position 10b, and the first mounting position 10a and the second mounting position 10b are arranged in an upper and lower interval; the rotating structure 20 is installed at the first mounting position 10a; the lifting structure 30 is installed at the second mounting position 10b; the stacking piece 40 includes a pressure cover 41 and a stacking shell 42, the pressure cover 41 is connected to the rotating structure 20, the rotating structure 20 is used to drive the pressure cover 41 to rotate, the stacking shell 42 is connected to the lifting structure 30, and the lifting structure 30 is used to drive the stacking shell 42 to rise and fall relative to the pressure cover 41; the stacking shell 42 has a stacking groove 40a and a plurality of glue openings 40b, the plurality of glue openings 40b are arranged at intervals around the periphery of the stacking shell 42, and the stacking groove 40a is used to stack battery electrodes.

[0046] In this embodiment, the main bracket 10 is fixed on the battery electrode gluing equipment, and the rotating structure 20 and the lifting structure 30 are detachably connected to the main bracket 10 through connecting parts respectively. The rotating structure 20 is located at the first installation position 10a of the main bracket 10, and the lifting structure 30 is located at the second installation position 10b of the main bracket 10, so that the rotating structure 20 is located above the lifting structure 30.

[0047] When multiple battery electrodes are stacked in the stacking trough 40a of the stacking shell 42, the lifting structure 30 is first controlled to drive the stacking shell 42 to move towards the direction close to the pressure cover 41, that is, the stacking shell 42 rises to the pressure cover 41, so that the pressure cover 41 can press the multiple battery electrodes located on the stacking shell 42; at this time, when the battery electrode gluing equipment moves to a position close to the spline manipulator, the rotating structure 20 of the spline manipulator is then controlled to drive the pressure cover 41 to rotate. Since the pressure cover 41 is pressed tightly against the stacking shell 42, the pressure cover 41 can drive the stacking shell 42 to rotate synchronously, so that the multiple battery electrodes can rotate while being pressed. In this way, the gluing mechanism of the battery electrode gluing equipment can be opposite to the multiple gluing openings 40b of the rotated stacking shell 42, so that the gluing mechanism can contact the side walls of the multiple battery electrodes in the stacking trough 40a of the stacking shell 42 through the gluing openings 40b, thereby gluing the multiple battery electrodes.

[0048] The spline manipulator of the present embodiment is connected with the stacking shell 42 of the stacking piece 40 by setting a lifting structure 30, and also sets a rotating structure 20 to be connected with the pressure cover 41 of the stacking piece 40, so that the spline manipulator can drive the multiple battery poles to rotate while pressing the multiple battery poles, so that it is convenient for the gluing mechanism to align the side walls of the multiple battery poles after rotation for gluing, and there is no need to set up multiple manipulators for gluing, thereby simplifying the structure of the battery pole piece gluing equipment.

[0049] In one embodiment, referring to Figure 1 and Figure 2 A plurality of key teeth 41a are provided on the side of the pressure cover 41 facing the material stacking shell 42, and the plurality of key teeth 41a are arranged at intervals around the periphery of the pressure cover 41; the material stacking shell 42 is provided with a plurality of key grooves 42a, and the plurality of key grooves 42a are all connected to the material stacking grooves 40a, and each key groove 42a is located between two adjacent glue openings 40b; each key tooth 41a is inserted into a key groove 42a, so that the pressure cover 41 and the material stacking shell 42 are matched and connected.

[0050] Specifically, by providing multiple key teeth 41a on the pressure cover 41 and multiple key grooves 42a on the stacking shell 42, that is, a spline structure is provided on the stacking piece 40, each key tooth 41a can be inserted in a key groove 42a, so that the stacking shell 42 and the pressure cover 41 are pressed more tightly; with such a configuration, when the rotating structure 20 drives the pressure cover 41 to rotate, the pressure cover 41 can cooperate closely with the stacking shell 42 through the key teeth 41a and the key grooves 42a, which not only allows the pressure cover 41 to effectively drive the stacking shell 42 to rotate synchronously, but also the pressure cover 41 and the stacking shell 42 will not slip when rotating, thereby improving the stability of the stacking piece 40 during movement and improving the gluing effect of multiple battery electrodes.

[0051] In one embodiment, referring to Figure 1 and Figure 2 The material stacking shell 42 includes a base 421 and a material shell, the base 421 is connected to the lifting structure 30; the material shell includes a bottom plate 422a and a plurality of protrusions 422b arranged on the bottom plate 422a, the plurality of protrusions 422b are arranged at intervals around the periphery of the bottom plate 422a, each protrusion 422b is provided with a key slot 42a and a limiting strip located on the bottom slot wall of the key slot 42a, and the plurality of protrusions 422b and the bottom plate 422a are enclosed to form a material stacking slot 40a and a plurality of glue openings 40b.

[0052] In this embodiment, the base 421 and the material shell are connected as a whole by screws and screw holes. The material shell is divided into a bottom plate 422a and a plurality of protrusions 422b. The plurality of protrusions 422b are all arranged on one side of the bottom plate 422a and are arranged at intervals around the periphery of the bottom plate 422a. The key slot 42a is arranged on the protrusion 422b, and a limit strip is arranged in the key slot 42a, so that after the key tooth 41a is inserted into the key slot 42a, the limit strip can also limit the position of the key tooth 41a, so that the stacking shell 42 and the pressure cover 41 are more tightly plugged in, thereby improving the stability of the stacking piece 40 during movement.

[0053] In one embodiment, referring to Figure 1 and Figure 2The key teeth 41a and the key slots 42a are both rectangular, triangular or polygonal. By designing the key teeth 41a and the key slots 42a to be rectangular, triangular or polygonal, the key teeth 41a and the key slots 42a have edges and corners, so that the pressure cover 41 and the stacking shell 42 will not slip when rotating, thereby improving the stability of the stacking member 40 during movement and improving the gluing effect of multiple battery pole pieces.

[0054] In one embodiment, referring to Figure 1 and Figure 2 The rotating structure 20 includes a first driving motor 21, a first transmission wheel 22, a first transmission belt 23, a first passive wheel 24 and a connecting shaft 25.

[0060] In this embodiment, the second drive motor 31 is fixed to the lower position of the main bracket 10 by screws and is spaced apart from the first drive motor 21; the second drive motor 31 drives the second transmission wheel 32 to rotate through the second transmission belt 33, so that the second transmission wheel 32 drives the transmission nut 34 to rotate synchronously. During the rotation of the transmission nut 34, the groove wall of its own spiral groove can drive the screw shaft 35 to rise and fall along the axial direction of the spiral groove.
