[0028] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0029] See also Figures 1 to 4 , the utility model is a material unloading and turning conveying device for welding battery sheets, a material suction component 5 and a turning mechanism for driving the material suction component 5 to turn over;

[0030] The material suction assembly 5 includes a mounting plate 51, a material pulling piece 52 and a material pressing piece 53. The material pulling piece 52 and the material pressing piece 53 are arranged on the same side of the mounting plate 51 and are spaced apart. The height of the material pressing piece 53 protruding from the mounting plate 51 is greater than the height of the material pulling piece 52 protruding from the mounting plate 51.

[0031] Specifically, in the present embodiment, there are two support columns 1, two lifting drive members 2, one lifting drive member 2 is arranged on one support column 1, there is one connecting rod 4, there are multiple suction components 5, and multiple suction components 5 are arranged in sequence along the length direction of the connecting rod 4. The suction component 5 is located directly above the conveying line body 6. Each suction component 5 includes a mounting plate 51, a pulling component 52 and a pressing component 53. When the suction component 5 absorbs the external battery cell finished product 100, the pulling component 52 and the pressing component 53 correct the flatness of the battery cell finished product 100, so that the battery cell finished product 100 can be corrected at the same time as it is transported, thereby improving production efficiency. The working principle is as follows: after the battery cell finished product 100 is processed on the external welding station, the welding surface of the battery cell finished product 100 faces upward, and the suction cup of the external transport device absorbs the welding surface of the battery cell finished product 100 and transports the battery cell finished product 100 to directly above the unloading flipping conveyor, and the lifting drive Component 2 drives the rotary drive component 3, the connecting rod 4 and several suction components 5 to rise synchronously and cooperate with the external transfer device. The rotary drive component 3 drives the connecting rod 4 to rotate so that the several suction components 5 absorb the external battery cell finished product 100 transferred by the external transfer device upward. At this time, the several suction components 5 absorb the use surface of the external battery cell finished product 100. Then the lifting drive component 2 drives the rotary drive component 3, the connecting rod 4 and several suction components 5 to move downward. At the same time, the rotary drive component 3 drives the connecting rod 4 to rotate 180° so that the several suction components 5 and the battery cell finished product 100 face the conveying line body 6. When the lifting drive component 2 drives the rotary drive component 3, the connecting rod 4, several suction components 5 and the battery cell finished product 100 to move downward and fit with the conveying line body 6, the several suction components 5 place the battery cell finished product 100 on the conveying line body 6, so that the welding surface of the battery cell finished product 100 fits with the surface of the conveying line body 6, completing the transfer and entering the conveying stage.

[0032] By setting up a suction assembly 5 consisting of a mounting plate 51, a material pulling piece 52 and a material pressing piece 53, the material pulling piece 52 and the material pressing piece 53 are arranged on the same side of the mounting plate 31 and are spaced apart, the height of the material pressing piece 53 protruding from the mounting plate 31 is greater than the height of the material pulling piece 52 protruding from the mounting plate 51, and the flipping mechanism drives the suction assembly to flip, so that the external battery cell finished product 100 can be quickly flipped during the transportation process, thereby protecting the use surface of the battery cell finished product and meeting the processing requirements. The suction assembly consisting of the mounting plate, the material pulling piece and the material pressing piece can realize synchronous correction of the transportation process, further ensuring the stability of production quality.

[0033] The number of the pressing pieces 53 is one row, and the number of the pulling pieces 52 is two rows. One row of pressing pieces 53 is located between two rows of pulling pieces 52, which generates upward suction on the opposite edges of the finished battery cell 100 and downward pressure on the middle of the finished battery cell 100, thereby completing the correction of the flatness of the finished battery cell 100.

[0034] The pressing member 53 includes an adjusting rod 531 and a pressing block 532. The adjusting rod 531 is arranged on the mounting plate 51. The adjusting rod 531 is used to adjust the longitudinal height between the lower surface of the pressing block 532 and the mounting plate 51, and to make appropriate adjustments according to the bending deformation of different battery cell finished products 100 to achieve production flexibility.

[0035] The pressing block 532 is provided with an arcuate surface 5321, and the arcuate surface 5321 is provided on the lower surface of the pressing block 532, so that the pressing block 532 and the finished battery cell 100 are in line contact, thereby reducing the contact area between the pressing block 532 and the finished battery cell 100, reducing the loss of the finished battery cell 100 caused by collision, and improving the stability of production quality.

[0036] The lifting drive member 2 includes a driving source 21, a slider 22 and a connecting plate 23. The driving source 21 is arranged on the support column 1 and drives the slider 22 to slide along the support column 1. One end of the connecting plate 23 is connected to the slider 22, and the other end of the connecting plate 23 is installed with a rotating driving member 3. The setting of the slider 22 plays a role in controlling the stability of the lifting direction of the suction component 5.

[0037] The downward flipping mechanism also includes a buffer member 7, which is arranged on the support column 1 and is located directly above the slider 22. The setting of the buffer member 7 limits the movement of the slider 22 in the longitudinal direction, while avoiding the possibility of collision between the suction component 5 and the external transfer device, thereby improving the production safety factor.

[0038] The buffer member 7 includes a base and an elastic member. The base is arranged on the support column 1, and the elastic member is arranged on the base. The elastic member is used to stop the slider 22, further limiting the lifting range of the slider 22, so as to achieve the purpose of safe production.

[0039] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
