The lamination table flow line is annular, and the number of the lamination tables 2 is set according to the length of the lamination table flow line.
The first pole piece is a positive pole piece, and the second pole piece is a negative pole piece; or, the first pole piece is a negative pole piece, and the second pole piece is a positive pole piece.
The equipment further comprises a rubberizing conveyor, and the rubberizing conveyor conveys the stacked battery core pole pieces on the lamination table to be rubberized. The rubberizing conveyer 5 is provided with a rubberizing station, when the rubberizing station is occupied, a lamination table circulation line continues to rotate, and the first rotary mechanical arm 6, the second rotary mechanical arm 7, the third rotary mechanical arm 3 and the fourth rotary mechanical arm 4 stop rotating lamination movement.

The first rotary manipulator 6, the second rotary manipulator 7, the third rotary manipulator 3 and the fourth rotary manipulator 4 are also provided with a lifting mechanism for controlling the lifting of the rotary manipulators.
Based on the technical scheme provided by the embodiment one, the lamination precision can be improved, the quality of the lithium battery is effectively improved, meanwhile, the lamination efficiency can be improved in the form of high-speed circulation lamination, and the structure of the multi-lamination platform can enable the system to have great redundancy, so that flexible expansion can be carried out, and the lamination efficiency is further improved.
Example two:
in the technical scheme provided by the embodiment I, the knockout plate is planar and is not guided in an arc shape. When the pole pieces adsorbed on the conveying belt move to the material beating position, the pole pieces are beaten into the material box by the whole surface of the material beating mechanism to be collected. In this case, the whole surface of the pole piece is adsorbed on the conveying belt, the pole piece has a large adsorption area, the size of the knockout plate is large enough to completely separate the pole piece from the conveying belt, and the knockout stroke is also large enough. This increases the size and cost of the apparatus and reduces efficiency. This effect is particularly strong when the device is run at increased speeds or when the size of the pole pieces is increased.
Based on the above problems, the present embodiment will discuss how to improve the knockout mechanism, and specifically, as shown in fig. 2 to 5, proposes a knockout device, which comprises a servo power assembly 61, an eccentric wheel 62 and a knockout assembly 63; the servo power assembly 61 is connected with the eccentric wheel 62 and drives the eccentric wheel to rotate; the knockout assembly 63 is connected with the eccentric wheel and driven by the eccentric wheel 62 to reciprocate; the knockout plate 633 of the knockout assembly 63 has an arc shape.
The technical scheme proposed based on the embodiment is as follows: the striking plate contacting the pole piece is made into an arc shape, and when the pole piece adsorbed on the conveying belt moves to a striking position, the pole piece is firstly guided to walk along the arc shape of the striking plate, so that the pre-separation effect is realized with the conveying belt. Therefore, the contact area of the pole piece and the conveying belt is reduced, the adsorption force is reduced, the knockout time and the stroke are shortened, and the efficiency of the equipment is greatly improved.
Example three:
the structure and principle of the knockout device will be further described with reference to the second embodiment. In the second embodiment, the knockout device comprises a servo power assembly 61, an eccentric wheel 62 and a knockout assembly 63; the servo power assembly 61 is connected with the eccentric wheel 62 and drives the eccentric wheel to rotate; the knockout assembly 63 is connected with the eccentric wheel and driven by the eccentric wheel 62 to reciprocate; the knockout plate 633 of the knockout assembly 63 has an arc shape.
In one example, the knockout assembly 63 further includes a movable assembly 631 connected to the eccentric and a pilot knockout pin 632. The movable assembly is used for connecting the eccentric wheel and the whole material beating assembly, and the driving force provided by the eccentric wheel is converted into the power of the material beating assembly.
In one example, the movable assembly 631 connected to the eccentric comprises: a drive plate 6311; an eccentric wheel limit hole 6312; rail slide 6313. The eccentric is inscribed in an eccentric limit hole 6312 of the drive plate 6311, and when the eccentric rotates, driving force is transmitted to the knockout assembly by pressure applied to the inner sidewall of the eccentric limit hole 6312. As shown in fig. 2-5, the eccentric limit hole 6312 is a slot circumscribing the eccentric drive portion and having a degree of freedom in the horizontal direction, and when the drive wheel rotates, it does not contact the drive plate in the horizontal direction and thus there is no force. And since the eccentric wheel limit hole 6312 limits the degree of freedom of the eccentric wheel driving portion in the vertical direction, it will be pressed by the eccentric wheel in the vertical direction. Under which the knockout assembly will reciprocate vertically along the rail slides 6313. Namely, the eccentric wheel 62 is connected with the movable assembly 631 through the arc-shaped driving plate 6311; when the eccentric wheel 62 rotates, it drives the movable component 631 to reciprocate through the guide rail sliding block 6313 and the eccentric wheel limit hole 6312.
Due to the design of the eccentric limit hole 6312, the reciprocating speed of the movable assembly 631 can be expressed as the product of the linear speed of the eccentric rotation and the vertical component of the eccentric speed at the present moment. If the servo-driven eccentric rotates at a constant speed, the reciprocating speed of the movable element 631 can be expressed by a sine or cosine trigonometric function. And in the process that the knockout mechanism moves downwards to the maximum stroke, the speed is gradually reduced. That is, the eccentric 62 reciprocates in the vertical direction relative to the rail sliding block 6313, and the movement speed of the movable assembly 631 in the vertical direction is the component of the linear velocity of the eccentric in the circular motion in the vertical direction; the eccentric wheel (62) reciprocates in the limit direction of the eccentric wheel limit hole 6312 of the movable component 631, and drives the movable component to have a velocity component of 0 in the horizontal direction.
In one example, the structure shown in fig. 2-5. The movable assembly 631 is connected with one end of a pilot knockout rod 632 through a connecting plate, and the other end of the pilot knockout rod 632 is provided with the arc-shaped knockout plate 633.
In one example, the knockout device is arranged above an inverted conveying belt, and the pole piece is adsorbed below the inverted conveying belt and moves along with the movement of the conveying belt. The cambered surface of the cambered ramming plate (633) is gradually contacted with the belt pulley along with the reciprocating motion of the eccentric wheel. And because the speed of the arc-shaped knockout plate gradually slows down in the process of approaching the conveying belt, the knockout plate approaches the belt at the gradually slowing down speed and knocks down the pole piece. After the pole piece is knocked down, the eccentric wheel drives the knock-out assembly to reach the maximum stroke, and the next period is started. After the eccentric wheel 62 rotates one circle under the driving of the servo power assembly 61, the transmission belt moves forward by one knockout station.
In one example, as shown in fig. 2-5, the servo power assembly 61 and the eccentric 62 are disposed on a fixed cross plate.
As shown in fig. 5, the eccentric rotates circumferentially at an angular velocity θ, which drives the knockout in the limiting direction (the direction perpendicular to the x direction) of the eccentric limiting hole 6312 to reciprocate.
As shown in fig. 6, the conveying belt 64 is conveyed upside down, the pole piece 65 is adsorbed under the belt, and the material beating mechanism beats materials from top to bottom.
The knockout device that provides based on this embodiment can with adsorb the pole piece on the conveyor belt is invertd, accurate beat the magazine the inside and collect. The striking plate contacting with the pole piece is made into an arc shape, when the pole piece adsorbed on the conveying belt moves to a striking position, the pole piece is firstly guided to walk along the arc shape of the striking plate, and therefore the pre-separation effect is achieved with the conveying belt. Therefore, the contact area of the pole piece and the conveying belt is reduced, the adsorption force is reduced, the knockout time and the stroke are shortened, and the efficiency of the equipment is greatly improved. And simple structure, reliable connection, easy assembly, convenient maintenance and convenient automatic production.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
