[0001] The present invention relates to the technical field of new energy vehicle battery production technology, and specifically to a new energy vehicle battery pole piece stacking machine. Background Art

[0002] The production of new energy batteries is the core technology in the production process of new energy vehicles. The battery pole piece stacking machine is one of the key equipment in the new energy battery production line. It is mainly used for precise die-cutting and lamination of battery pole pieces. Die-cutting is to cut large pieces of pole piece materials according to predetermined sizes and shapes, while lamination is to stack the die-cut pole pieces together in order and intervals, and insert diaphragms between the pole pieces to ensure that the positive and negative poles will not be in direct contact when the battery is working.

[0003] The existing new energy vehicle battery electrode stacking machine needs to use a robot to transfer the positive and negative electrode sheets from the positive electrode conveyor belt and the negative electrode conveyor belt and stack them during stacking. The moving speed of the robot and the transmission speed of the conveyor belt need to be adapted to each other, but the speed difference between the moving speed of the robot and the transmission speed of the conveyor belt will accumulate and become larger during long-term operation, until it affects the normal progress of the stacking operation. Therefore, it is necessary to regularly debug the speeds of the two, but regular debugging often requires suspension of production operations.

When the elastic piston rises and resets, the pressure plate first translates inward and then descends. Every time the manipulator performs a stacking operation on the stacking plate, the pressure plate can always be adaptively pressed on the edge of the top diaphragm, thereby ensuring tight stacking.

DETAILED DESCRIPTION

[0027] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] like Figure 1-Figure 7As shown, the present invention provides a technical solution: a new energy vehicle battery pole piece stacking machine, including a stacking base 1 and a piston assembly 12, a screw rod 2 is arranged in the middle of the stacking base 1, and the end of the screw rod 2 is connected to a servo motor 3, the outer wall of the screw rod 2 is sleeved with a moving seat 4, and piston push rods 5 are fixed on both sides of the moving seat 4, the outer wall of the piston push rod 5 is sleeved with a first oil tank 6, and an oil pipe 7 is arranged on the side of the first oil tank 6, and a second oil tank 8 is fixed at the end of the oil pipe 7, and a transmission push rod 9 is penetrated inside the second oil tank 8, an electric lifting rod 10 is fixed at the end of the transmission push rod 9, and a manipulator 11 is connected to the bottom of the electric lifting rod 10, the piston assembly 12 is arranged at the ends of the piston push rod 5 and the transmission push rod 9, and the piston assembly 12 is located inside the first oil tank 6 and the second oil tank 8, the piston assembly 12 includes a main piston 1201, a micro piston 1202, a micro piston 1203, a micro piston 1204, a micro piston 1205, a micro piston 1206, a micro piston 1207, a micro piston 1208, a micro piston 1209, a micro piston 12101, a micro piston 12102, a micro piston 12103, a micro piston 12104, a micro piston 12105, a micro piston 12106, a micro piston 12107, a micro piston 12108, a micro piston 12109, a micro piston 12101, a micro piston 1210 A type push rod 1202 and an adjusting piston 1203, a micro push rod 1202 is arranged inside the main piston 1201, and the end of the micro push rod 1202 is connected to the adjusting piston 1203, a pole piece conveyor belt 13 is arranged below the second oil tank 8, and the first oil pump pipe 14 and the second oil pump pipe 15 are respectively arranged at both ends of the upper surface of the second oil tank 8, the adjusting piston 1203 is slidably connected to the inside of the main piston 1201, and the outer port structure of the adjusting piston 1203 and the main piston 1201 is adapted to the inner port structure of the first oil tank 6 and the second oil tank 8, a slide rail is arranged on one side of the electric lifting rod 10, and pressure sensors are arranged at both ends of the inner side of the slide rail and on the side of the first oil tank 6 close to the moving seat 4, a column 16 is arranged between the second oil tank 8, and a roller 17 is arranged on the surface of the column 16, and a diaphragm 18 is passed between the rollers 17;

[0029] The specific operation is as follows: the servo motor 3 drives the screw rod 2 to rotate so that the moving seat 4 carrying the laminated carrier plate 1904 moves left and right. When the moving seat 4 carrying the laminated carrier plate 1904 moves to a certain end of the screw rod 2, the piston push rod 5 on one side of the moving seat 4 is pressed into the first oil tank 6, and the piston push rod 5 on the other side of the moving seat 4 is drawn out from the first oil tank 6. At this time, the oil inside the first oil tank 6 on both sides of the moving seat 4 is used as a transmission medium to transmit force, so that the transmission push rods 9 inside the second oil tank 8 on both sides are extended and contracted respectively;

[0030] Based on the above description, for example: when the lamination carrier plate 1904 moves to the left end of the screw rod 2, the oil inside the first oil tank 6 on the left side is forced to enter the second oil tank 8 so that the transmission push rod 9 is fully extended, and the oil inside the first oil tank 6 on the right side is forced to retract the transmission push rod 9 into the second oil tank 8. At this time, the transmission push rod 9 on the left side moves from the pole piece conveyor belt 13 to the top of the moving seat 4, and the transmission push rod 9 on the right side moves from the top of the lamination base 1 to the top of the pole piece conveyor belt 13 on the right side. At this time, the manipulator 11 on the left side moves the pole piece on the surface of the pole piece conveyor belt 13. The electric lifting rod 10 is lowered and placed on the diaphragm 18 on the surface of the stacking plate 1904. Similarly, when the stacking plate 1904 moves to the right end of the screw rod 2, the above operation is also performed. At this time, the transmission push rod 9 on the right side is fully extended to place the pole piece on the diaphragm 18, and the front and rear pole pieces are separated by the diaphragm 18. Therefore, when the stacking plate 1904 moves left and right through the rotation of the screw rod 2, the oil can be transmitted by the movement of the moving seat 4 so that the manipulator 11 can move back and forth between the pole piece conveyor belt 13 and the stacking plate 1904 to cyclically transfer the pole pieces for stacking;

[0031] If the moving seat 4 fails to trigger the pressure sensor, and the monitoring camera or positioning sensor detects that the manipulator 11 on one side has reached the top of the pole piece, while the manipulator 11 on the other side has not yet reached the top of the laminated carrier plate 1904, the moving speeds of the manipulators 11 on both sides and the transmission speeds of the pole pieces will be different and incompatible, which may easily lead to the pole piece being unable to be accurately placed on the diaphragm 18. Based on this, when the above situation occurs, oil is injected into the second oil tank 8 located above the pole piece through the first oil pump pipe 14, and at the same time, the micro push rod 1202 inside the first oil tank 6 contracts, so that the adjustment The piston 1203 is close to the main piston 1201. At this time, the moving seat 4 can still move to one side, and the transmission push rod 9 above the pole piece changes from retracting movement to extending movement, so that the transmission push rod 9 carries the manipulator 11 to move synchronously with the pole piece being transmitted and pick it up, and does not affect the movement of the moving seat 4. When the moving seat 4 moves in the opposite direction, the micro push rods 1202 inside the first oil tank 6 and the second oil tank 8 are extended and retracted to adjust the distance between the regulating piston 1203 and the main piston 1201 to control the oil content, so that the manipulator 11 can accurately move to the top of the stacking plate 1904 after picking up the pole piece.

[0032] Similarly, if the moving seat 4 triggers the pressure sensor, but the pressure sensor at either end of the slide rail is not triggered, based on whether the moving state of the transmission push rod 9 is retracted or extended, oil is injected or discharged through the first oil pump pipe 14 and the second oil pump pipe 15, and the micro push rod 1202 is extended and retracted to adjust the distance between the adjusting piston 1203 and the main piston 1201. While maintaining the normal reciprocating movement of the moving seat 4 carrying the stacking plate 1904, ensure that the moving speed of the manipulator 11 is adapted to the transmission speed of the pole piece, so that the manipulator 11 can accurately move the pole piece from above the pole piece conveyor belt 13 to the stacking plate 1904, and the pole piece is separated by the diaphragm 18 through the reciprocating movement of the stacking plate 1904, thereby solving the problem that the speed difference between the moving speed of the manipulator 11 and the transmission speed of the pole piece becomes larger over time and affects the normal stacking operation.

[0033] like Figure 1-Figure 7 As shown, a lamination assembly 19 is fixed on the surface of the movable seat 4, and the lamination assembly 19 includes a base 1901, an oil box 1902, an elastic piston 1903 and a lamination support plate 1904. The oil box 1902 is fixed on the top of the base 1901, and the elastic piston 1903 is penetrated on the top of the oil box 1902. The lamination support plate 1904 is fixed on the top of the elastic piston 1903. The lamination assembly 19 also includes a first pipe 1905 and a first telescopic rod 1906. The first pipe 1905 is provided on both sides of the oil box 1902, and the first telescopic rod 1906 is penetrated inside the first pipe 1905. The lamination assembly 19 also includes a second The pipe 1907, the second telescopic rod 1908 and the pressing plate 1909, the end of the first telescopic rod 1906 is connected to the second pipe 1907, and the second telescopic rod 1908 is penetrated on the top of the second pipe 1907, and the pressing plate 1909 is fixed on the top of the second telescopic rod 1908, the first telescopic rod 1906 is hollow, and the second pipe 1907 is connected to the first pipe 1905 through the first telescopic rod 1906, and the laminated assembly 19 also includes a colloid septum 1910, and the end of the first telescopic rod 1906 is embedded with the colloid septum 1910, the colloid septum 1910 is distributed in a ring shape, and the colloid septum 1910 is a flexible structure;

[0034] The specific operation is as follows: when the electric lifting rod 10 drives the manipulator 11 to place the pole piece on the laminated carrier plate 1904, the manipulator 11 descends and presses the laminated carrier plate 1904. At this time, the elastic piston 1903 is pressed into the oil box 1902 by force, so that the oil in the oil box 1902 enters the first pipe 1905 to push the first telescopic rod 1906 to extend. At this time, the pressure plate 1909 releases the clamping of the diaphragm 18, and the oil pressure in the first pipe 1905 rises during the subsequent downward pressure of the elastic piston 1903, and the colloid diaphragm 1910 is flushed open, so that the oil enters the second pipe 1907, so that the second telescopic rod 1908 carries the pressure plate 1909 to lift, so that the pressure plate 1909 is separated from the edge of the diaphragm 18;

[0035] When the manipulator 11 rises, the elastic piston 1903 resets and rises. At this time, the first telescopic rod 1906 retracts first, so that the pressure plate 1909 is first translated to the top of the diaphragm 18. In the subsequent rising process of the elastic piston 1903, the colloid diaphragm 1910 is reversely opened due to the suction force, so that the oil in the second pipe 1907 returns to the first pipe 1905, so that the pressure plate 1909 descends and presses on the edge of the diaphragm 18 again, thereby ensuring that the laminations are tight.

[0036] Based on the lifting and lowering force of the manipulator 11, the elastic piston 1903 is forced to expand and contract. When the elastic piston 1903 is pressed down and contracted, the oil is used as the transmission medium and the space is separated by the colloid diaphragm 1910, so that the pressure plate 1909 first translates outward and then rises. When the elastic piston 1903 rises and resets, the pressure plate 1909 first translates inward and then descends. Every time the manipulator 11 performs a stacking operation on the stacking support plate 1904, the pressure plate 1909 can always be adaptively pressed on the edge of the top diaphragm 18, thereby ensuring that the stacking is tight.

[0037] In summary, when the new energy vehicle battery electrode stacking machine is used, first, a die-cutting mechanism is provided at one end of the electrode conveyor belt 13 away from the column 16 for cutting the large electrode into electrode pieces of required size and shape, and the cut electrode pieces are placed on the electrode conveyor belt 13 for transmission;

[0038] The servo motor 3 drives the screw rod 2 to rotate so that the moving seat 4 carrying the laminated carrier plate 1904 moves left and right. When the moving seat 4 carrying the laminated carrier plate 1904 moves to a certain end of the screw rod 2, the piston push rod 5 on one side of the moving seat 4 is pressed into the first oil tank 6, and the piston push rod 5 on the other side of the moving seat 4 is drawn out from the first oil tank 6. At this time, the oil inside the first oil tank 6 on both sides of the moving seat 4 is transmitted as a transmission medium, so that the transmission push rods 9 inside the second oil tank 8 on both sides are extended and contracted respectively.

[0039] When the stacking plate 1904 is moved left and right by the rotation of the screw rod 2, the oil is transmitted by the movement of the moving seat 4 so that the manipulator 11 can move back and forth between the electrode conveyor belt 13 and the stacking plate 1904 to cyclically transfer the electrode for stacking;

[0040] Based on whether the moving state of the transmission push rod 9 is retracted or extended, the oil is injected or discharged through the first oil pump pipe 14 and the second oil pump pipe 15, and the distance between the regulating piston 1203 and the main piston 1201 is adjusted in coordination with the extension and contraction of the micro push rod 1202. While maintaining the normal reciprocating movement of the moving seat 4 carrying the stacking plate 1904, the moving speed of the manipulator 11 is ensured to be adapted to the transmission speed of the pole piece, so that the manipulator 11 can accurately move the pole piece from above the pole piece conveyor belt 13 to the stacking plate 1904, and the pole piece is separated by the diaphragm 18 through the reciprocating movement of the stacking plate 1904;

[0041] Based on the lifting force of the manipulator 11, the elastic piston 1903 is forced to expand and contract. When the elastic piston 1903 is pressed down and contracted, the oil is used as a transmission medium and the space separation of the colloid diaphragm 1910 is used to make the pressure plate 1909 first translate outward and then rise. When the elastic piston 1903 rises and resets, the pressure plate 1909 first translates inward and then descends, so that each time the manipulator 11 performs a lamination operation on the lamination carrier 1904, the pressure plate 1909 can always be adaptively pressed on the edge of the uppermost diaphragm 18;

[0042] The internal space of the first oil tank 6 and the second oil tank 8 can be changed into a cylindrical structure, and the adjusting piston 1203 and the main piston 1201 are adaptively adjusted, that is, the adjusting piston 1203 and the main piston 1201 are also cylindrical structures to facilitate piston movement.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
