[0024] The specific implementation modes of the present utility model are introduced with reference to the accompanying drawings.

[0025] refer to Figure 1 As shown in the figure, the feeding mechanism is installed on the large plate 100 of the winding machine, which is used to move the sliced ​​electrodes 105 one by one to the entry table 102. Then the entry table 102 pushes the electrode 105 to the winding needle according to the winding process of the winding needle to be wound into a battery cell. The inclination angle of the entry table 102 is the entry angle of the electrode 105 when it is wound.

[0026] refer to Figures 1 to 4 A feeding mechanism includes a material moving device 1, a material suction head 5, and a film entry platform 102. The material moving device 1 includes a moving component 2 and a swinging component 3. The moving component 2, the swinging component 3 and the material suction head 5 are sequentially connected by transmission. The moving component 2 drives the material suction head 5 and the swinging component 3 to move back and forth between the pre-positioning platform 101 and the film entry platform 102. The swinging component 3 drives the material suction head 5 to switch between a first posture 103 and a second posture 104. At the pre-positioning platform 101, the material suction head 5 sucks the electrode 105 on the pre-positioning platform 101 in the first posture 103. At the film entry platform 102, the material suction head 5 places the electrode 105 on the film entry platform 102 in the second posture 104.

[0027] It needs to be further explained that the first posture 103 of the suction head 5 is in a horizontal state, and the pre-positioning table 101 needs to pre-position the pole piece 105 to ensure that the pole piece 105 can be stably fed into the sheet, and the second posture 104 is in an inclined state, and the inclination angle of the second posture 104 is the same as the inclination angle of the sheet feeding table 102. According to the winding feeding angle of different battery cells, most of the inclination angles of the second posture 104 are between 10°-45°. In the second posture 104, the suction head 5 and the sheet feeding table 102 are parallel to each other, so that the pole piece 105 can be placed on the sheet feeding table 102 more stably.

[0028] The suction head 5 of the feeding mechanism of this embodiment sucks the electrode piece 105 on the pre-positioning table 101 through vacuum, drives the suction head 5 and the electrode piece 105 to move between the pre-positioning table 101 and the sheet-entry table 102 through the moving component 2, and drives the suction head 5 and the electrode piece 105 to rotate to a posture matching the sheet-entry table 102 through the swing component 3, so as to better place the electrode piece 105 on the sheet-entry table 102 and complete the feeding of the electrode piece 105.

[0029] In order to drive the suction head 5 to move between the pre-positioning platform 101 and the film feeding platform 102, in this embodiment, Figures 1 to 4 The moving assembly 2 includes a moving seat 21, a moving guide rail 22, a screw pair 23 and a moving motor 24. The moving seat 21 is installed between the moving guide rail 22 and the screw pair 23. The swing assembly 3 is installed on the moving seat 21. The moving motor 24 is connected to the moving seat 21 through the screw pair 23. The moving motor 24 drives the moving seat 21 to move linearly along the moving guide rail 22.

[0030] It should be further explained that the movable guide rail 22 is installed on the mounting plate 25, the mounting plate 25 is fixed on one side of the large plate 100, the screw pair 23 is installed on the mounting plate 25 through the bearing seat 26, and the movable motor 24 is installed on the mounting plate 25 through the motor seat 27.

[0031] It can be understood that, in such a configuration, the movable guide rail 22 and the screw pair 23 are arranged between the pre-positioning platform 101 and the film input platform 102, and the movable seat 21 is installed between the nut of the screw pair 23 and the slide seat on the guide rail. The movable motor 24 can well drive the movable seat 21 and the swing assembly 3, the lifting assembly 4, and the suction head 5 to move in a straight line along the movable guide rail 22 through the screw pair 23, thereby driving the suction head 5 to move back and forth between the pre-positioning platform 101 and the film input platform 102.

[0032] In order to drive the suction head 5 to swing between the first posture 103 and the second posture 104, in this embodiment, reference Figures 1 to 4The swing assembly 3 includes a swing seat 31, a swing shaft 32 and a swing cylinder 33. The swing seat 31 is connected to the moving seat 21 through the swing shaft 32. The swing cylinder 33 is arranged between the moving seat 21 and the swing seat 31. The swing cylinder 33 drives the swing seat 31 to rotate around the swing shaft 32.

[0033] It can be understood that, in such a configuration, one end of the swing cylinder 33 is pivoted to the moving seat 21, and the driving end of the other end is pivoted to the swing seat 31, the swing shaft 32 is fixed on the moving seat 21, and the swing seat 31 is sleeved on the swing shaft 32, so that the swing seat 31 can rotate relative to the swing shaft 32 when driven by the swing cylinder 33, thereby driving the lifting assembly 4 and the suction head 5 to rotate, so that the suction head 5 can rotate and switch between the horizontal first posture 103 and the inclined second posture 104.

[0034] In order to drive the suction head 5 to suck the electrode 105 on the pre-positioning table 101 and place it on the sheet loading table 102, in this embodiment, Figures 1 to 4 The material moving device 1 further comprises a lifting assembly 4 , which is disposed on the swing seat 31 , and a suction head 5 is connected to the lifting assembly 4 , and the lifting assembly 4 drives the suction head 5 to move up and down relative to the swing seat 31 .

[0035] It can be understood that, in such a configuration, the lifting component 4 is installed on the swing seat 31, the suction head 5 is installed on the lifting component 4, the suction head 5 and the lifting component 4 are driven together by the swing component 3, and at the pre-positioning platform 101, the swing component 3 drives the lifting component 4 and the suction head 5 to rotate to the first posture 103, the lifting component 4 drives the suction head 5 down to the pre-positioning platform 101, and the electrode 105 is sucked by the negative pressure of the suction head 5, and then the lifting component 4 drives the suction head 5 to rise; at the film input platform 102, the swing component 3 drives the lifting component 4 and the suction head 5 to rotate to the second posture 104, then the lifting component 4 drives the suction head 5 down to the film input platform 102, and then, the suction head 5 places the electrode 105 on the film input platform 102 after breaking the vacuum, and finally the lifting component 4 drives the suction head 5 to rise.

[0036] In order to better drive the suction head 5 to rise and fall, in this embodiment, reference Figures 1 to 4The lifting assembly 4 includes a first lifting seat 41, a first lifting guide rail 42, a first lifting cylinder 43, a second lifting seat 44, a second lifting guide rail 45 and a second lifting cylinder 46. The first lifting guide rail 42 and the first lifting cylinder 43 are installed on the swing seat 31. The first lifting seat 41 is connected to the driving end of the first lifting cylinder 43 by transmission, and is slidably connected to the first lifting guide rail 42. The first lifting cylinder 43 drives the first lifting seat 41 to move up and down along the first lifting guide rail 42; the second lifting guide rail 45 and the second lifting cylinder 46 are installed on the first lifting seat 41, the second lifting seat 44 is connected to the driving end of the second lifting cylinder 46 by transmission, and is slidably connected to the second lifting guide rail 45, the suction head 5 is installed on the second lifting seat 44, and the second lifting cylinder 46 drives the second lifting seat 44 and the suction head 5 to move up and down along the second lifting guide rail 45.

[0037] It can be understood that with such an arrangement, the lifting stroke of the suction head 5 is made larger and more precise through the first lifting cylinder 43 and the second lifting cylinder 46, so that it can adapt to more machine models, and can be well adapted to different film entry angles and different height differences between the pre-positioning table 101 and the film entry table 102, thereby ensuring that the suction head 5 can accurately absorb the pole piece 105 on the pre-positioning table 101 and place it on the film entry table 102.

[0038] In order to optimize the structure of the lifting assembly 4, in this embodiment, reference Figure 4 The driving end of the first lifting cylinder 43 is connected to the first lifting seat 41 through an L-shaped first connecting block 47.

[0039] It can be understood that, with such a configuration, the first connecting block 47, through the L-shaped structure, allows the first lifting cylinder 43 to be installed at a position slightly away from the swing seat 31, so that the first lifting cylinder 43 on the swing seat 31 can be selected with a cylinder of larger cylinder diameter, which facilitates the installation of the first lifting cylinder 43. At the same time, a first lifting seat 41 with a smaller volume can also be selected to reduce the volume of the lifting assembly 4.

[0040] In order to further optimize the structure of the lifting assembly 4, in this embodiment, refer to Figure 4 The driving end of the second lifting cylinder 46 is connected to the second lifting seat 44 through a second connecting block 48, and the second lifting seat 44 is connected to the suction head 5 through an L-shaped third connecting block 49.

[0041] It can be understood that, with such an arrangement, the second lifting cylinder 46 is connected to the second lifting seat 44 through the second connecting block 48, so that the second lifting cylinder 46 and the second lifting seat 44 are arranged side by side and parallel to each other on the first lifting seat 41, which maximizes the area on the first lifting seat 41. The third connecting block 49 has an L-shaped structure, so that the suction head 5 can be installed at a more suitable position away from the second lifting seat 44, while ensuring that the suction head 5 and the second lifting seat 44 are stably installed.

[0042] In order to adjust the position of the suction head 5, in this embodiment, refer to Figure 4 The third connecting block 49 is provided with an adjusting hole 491 , and a bolt for connecting the suction head 5 is provided in the adjusting hole 491 .

[0043] It can be understood that, with such a configuration, the adjustment hole 491 is an oblong hole, and the bolt connected to the suction head 5 can be moved in the adjustment hole 491 to adjust the position, thereby adjusting the position of the suction head 5 relative to the lifting assembly 4. In this way, the position of the suction head 5 can be adjusted according to the pole pieces 105 of different widths, thereby achieving a better effect of sucking the pole pieces 105.

[0044] In order to ensure that the suction head 5 can stably absorb the electrode 105, in this embodiment, reference Figure 3 and Figure 4 The lower end surface of the suction head 5 is provided with two suction nozzles 51 connected to an external air source.

[0045] It should be further explained that the two suction nozzles 51 are arranged side by side below the suction head 5. The suction nozzle 51 forms a negative pressure through an external air source to ensure that the suction nozzle 51 can stably absorb the electrode 105 on the pre-positioning table 101, and place the electrode 105 on the sheet entry table 102. The elasticity of the leather cup of the suction nozzle 51 itself is used for buffering to prevent the suction head 5 from falling excessively and to prevent the suction head 5 from colliding with the pre-positioning table 101 and the sheet entry table 102, thereby protecting the safety of the suction head 5.

[0046] The suction head 5 of the embodiment of the present application absorbs the electrode 105 on the pre-positioning table 101 through vacuum, drives the suction head 5 and the electrode 105 to move between the pre-positioning table 101 and the film entry table 102 through the moving component 2, and drives the suction head 5 to rise and fall through the lifting component 4 controlled by two lifting strokes, so as to adapt to models with different film entry angles and different height differences between the pre-positioning table 101 and the film entry table 102, to ensure that the suction head 5 can accurately absorb the electrode 105 on the pre-positioning table 101 and place it on the film entry table 102, and drive the suction head 5 and the electrode 105 to rotate to a posture matching the film entry table 102 through the swing component 3, so as to better place the electrode 105 on the film entry table 102 and complete the feeding of the electrode 105.

[0047] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
