[0002] The battery cell of a lithium-ion battery is mainly composed of a positive electrode sheet, a negative electrode sheet, and a separator separating the positive electrode sheet and the negative electrode sheet. At present, the processes for preparing battery cells mainly include stacking process and winding process. Compared with the wound lithium-ion battery prepared by the winding process, the stacked lithium-ion battery prepared by the stacking process has the advantages of high energy density, high voltage platform, and small battery internal resistance, and has been widely used in the process of preparing lithium-ion batteries.

[0003] However, compared with wound cells, stacked cells have poor compactness, so the rough space of stacked cells is large and inconvenient to take.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 10 The present invention provides a technical solution: a square aluminum shell lithium battery cell production device, comprising a frame 1 and an anode sheet placing table 5, an anode sheet coating table 6, a stacking platform 7, a cathode sheet coating table 8 and a cathode sheet placing table 9 arranged on the frame 1, a diaphragm cloth winding roller 2 is installed in the middle of the side wall of the frame 1, a first guide roller 3 is arranged below the diaphragm cloth winding roller 2, a mechanical mounting plate 14 is installed below the first guide roller 3 for limited sliding, a bracket 15 is fixedly arranged at the lower end of the mechanical mounting plate 14, a plurality of groups of second guide rollers 4 are arranged on the bracket 15, and an anode sheet material taking manipulator assembly 10, a first stacking manipulator assembly 11, a cathode sheet material taking manipulator assembly 12 and a second stacking manipulator assembly 13 are arranged in sequence at the front end of the mechanical mounting plate 14 from left to right. The upper end surfaces of the stacking robot assembly 13, the anode sheet glue coating station 6 and the cathode sheet glue coating station 8 are all provided with placement grooves, and two groups of upper and lower symmetrical glue boxes 30 are arranged on the left and right sides of each group of placement grooves, and each group of glue boxes 30 is driven by a pushing assembly and performs rectangular trajectory movement, and the pushing assembly is powered by the robot assembly; each group of glue boxes 30 is provided with a first glue roller 31 and a second glue roller 32, the first glue roller 31 is rotatably installed in the glue box 30 through the second central axis 37 and is in direct contact with the glue liquid, the second glue roller 32 is rotatably installed on the glue box 30 through the first central axis 33, and the first central axis 33 and the second central axis 37 are driven by a linkage assembly to perform synchronous and unidirectional rotational motion, so as to apply the glue liquid to the upper and lower sides of the electrode.

[0030] Furthermore, the present invention sets four groups of robot assemblies and cooperates with two groups of glue coating stations, so that multiple processes such as sheet removal, gluing and stacking can be carried out continuously without human intervention, and a roller gluing method is adopted to make the glue adhere to the surface of the electrode sheet more evenly, which not only solves the problem of poor compactness of stacked battery cells, but also overcomes the problem that the ordinary gluing method increases the thickness and weight of the battery cell, causing its surface to be uneven, which creates difficulties in the subsequent assembly into a battery pack.

[0031] like Figure 5-Figure 10As shown, the anode sheet picking robot assembly 10, the first stacking robot assembly 11, the cathode sheet picking robot assembly 12 and the second stacking robot assembly 13 are all provided with a pushing frame 16, and the upper end surfaces of the anode sheet gluing station 6 and the cathode sheet gluing station 8 are both provided with a connecting frame 17 for limited sliding installation, the upper end of the connecting frame 17 abuts against the connected pushing frame 16, and the lower end of the connecting frame is fixedly connected with a vertical pushing bar 18.

[0032] Furthermore, the four groups of manipulator components have the same structure, all of which are composed of a mounting plate, a cylinder and a suction cup. The pushing frame 16 is a door-type structure and is slidably sleeved on the piston column of the cylinder. The upper end surface of the suction cup is fixedly provided with four guide rods. The upper ends of the guide rods pass through the pushing frame 16 and are fixedly connected to the limiting plate. The lower end of the limiting plate is provided with a spring, which is sleeved on the guide rod. This arrangement allows the pushing frame 16 to squeeze the connecting frame 17 before the suction cup contacts the pole piece.

[0033] like Figure 1-Figure 3 As shown, the vertical push strip 18 extends into the gluing platform and is connected to the pushing assembly, which includes a transverse moving plate 20, a return spring 22, a cylindrical cam 24, a rotating shaft 25, an eccentric wheel 26, a square moving frame 27, a connecting block 28 and a limiting frame 29. One end of the connecting block 28 is fixedly connected to the glue box 30, and the other end of the connecting block 28 passes through the limiting frame 29 and is fixedly connected to the square moving frame 27. The limiting frame 29 is limitedly slidably installed in the gluing platform. The square moving frame 27 is sleeved on the outside of the eccentric wheel 26, and the eccentric wheel 26 is rotatably installed on the gluing platform through the rotating shaft 25. The end of the rotating shaft 25 is also fixedly sleeved with a cylindrical cam 24. The wheel groove of the cylindrical cam 24 is composed of two groups of half-turn spiral grooves. A cylindrical pin 23 is inserted in the wheel groove of the cylindrical cam 24. The cylindrical pin 23 is fixedly connected to the transverse moving plate 20, and the transverse moving plate 20 is limitedly slidably installed in the gluing platform. A return spring 22 is fixedly connected to one end of the transverse moving plate 20 away from the square moving frame 27 , and an inclined groove 21 is provided on one side of the transverse moving plate 20 away from the cylindrical pin 23 . A toggle column 19 is inserted into the inclined groove 21 , and the toggle column 19 is fixedly connected to the vertical push bar 18 .

[0034] Furthermore, by forming a multi-stage linkage mechanical assembly including a movable plate, a return spring 22, a cylindrical cam 24, a rotating shaft 25, an eccentric wheel 26, a square movable frame 27, a connecting block 28 and a limit frame 29, the glue box 30 can adaptively perform a rectangular trajectory movement according to the motion state of the manipulator assembly. When the manipulator assembly moves downward, the glue box 30 first moves in a direction away from the placement slot and then moves upward, so as to facilitate the normal placement or removal of the anode sheet or cathode sheet into or out of the placement slot; when the manipulator assembly moves upward, the glue box 30 first moves in the direction of the placement slot and then moves downward, so as to facilitate the normal gluing process of the next group of electrodes.

[0035] Specifically, the first lamination robot assembly 11 moves to the top of the anode sheet coating station 6, and the cylinder thereon drives the suction cup and the push frame 16 to move downward. In this process, the push frame 16 presses the connecting frame 17 downward, so that the connecting frame 17 drives the vertical push bar 18 to move downward, and the toggle column 19 on the vertical push bar 18 acts on the inclined groove 21, so that the lateral moving plate 20 is forced to squeeze the reset spring 22 and drive the cylindrical pin 23 to move in the direction away from the square moving frame 27, and the cylindrical pin 23 acts on the wheel groove of the cylindrical cam 24, so that the cylindrical The cam 24 is driven by the force to rotate the clockwise rotating shaft 25 180°, so that the end of the eccentric wheel 26 first contacts the left side wall of the square moving frame 27 and then contacts the upper end wall, and the square moving frame 27 acts on the glue box 30 by acting on the connecting block 28 and the limit frame 29, and the limit frame 29 performs a straight line movement up and down in the glue coating table, so that the two adjacent groups of glue boxes 30 first move together in the direction away from the placement groove and then move longitudinally in opposite directions, so that the second glue roller 32 first presses against the upper and lower sides of the edge of the anode sheet for horizontal coating and then releases and moves away.

[0036] like Figure 5 , Figure 8 as well as Fig.10 As shown, the linkage assembly includes a spur gear 38 and a fixed rack 39, one side of the fixed rack 39 is fixedly arranged on the bottom wall of the placement groove, and the other side of the fixed rack 39 is meshedly connected with the spur gear 38, the end of the second central shaft 37 extends out of the glue box 30 and is coaxially fixedly connected with the spur gear 38, the end of the first central shaft 33 is fixedly sleeved with a driven wheel 34, the reversing wheel 35 is meshedly connected to the driving wheel 36, and the driving wheel 36 is fixedly sleeved on the second central shaft 37. A notch is provided on the side where two adjacent groups of glue boxes 30 are close to each other, and the second glue roller 32 partially extends out of the notch and contacts the surface of the pole piece. A glue liquid placement cavity for accommodating the first glue roller 31 is also provided inside the glue box 30, and a glue-on port connected to the glue liquid placement cavity is provided on the outer wall of the glue box 30.

[0037] Furthermore, by arranging the spur gear 38, the fixed rack 39, the driven wheel 34, the reversing wheel 35 and the driving wheel 36 for use in cooperation, the horizontal movement of the rubber box 30 itself can be converted into the synchronous and same-direction rotational movement of the first rubber roller 31 and the second rubber roller 32, which not only reduces the number of power devices installed to drive the rubber rollers, but also the first rubber roller 31 and the second rubber roller 32 will only rotate when they are in contact with the pole piece, thereby reducing the leakage of glue to a certain extent.

[0038] Specifically, Fig.10As shown, since the rubber box 30 moves in a rectangular trajectory, when the rubber box 30 moves horizontally in a direction away from the placement groove, the spur gear 38 thereon meshes with the fixed rack 39, so that the second center shaft 37 rotates clockwise while moving horizontally with the rubber box 30, and the driving wheel 36 on the second center shaft 37 acts on the driven wheel 34 through the reversing wheel 35, so that the first center shaft 33 and the second center shaft 37 rotate in the same direction, thereby realizing the synchronous and same-direction rotation of the first rubber roller 31 and the second rubber roller 32.

[0039] like Figure 1-5 As shown, a lifting platform is installed on the stacking platform 7, and L-shaped pressing plates are arranged on both the front and rear sides of the lifting platform for pressing the diaphragm. The mechanical mounting plate 14 is driven by the driving assembly and moves horizontally on the frame 1, and three sets of linearly distributed second guide rollers 4 are installed on the upper limit of the bracket 15.

[0040] Furthermore, the driving assembly includes a horizontally arranged hydraulic cylinder, and by arranging a second guide roller 4, the diaphragm cloth can be further pulled and guided so that it can be stacked on the stacking platform 7 more flatly.

[0041] When the present invention is in use: first, stack the end of the diaphragm cloth in one layer on the stacking carrier 7, then turn on the driving assembly to drive the mechanical mounting plate 14 to perform horizontal reciprocating motion, at this time, the mechanical mounting plate 14 drives the four groups of manipulator assemblies to move to the right first, the anode sheet material taking manipulator assembly 10 is located directly above the anode sheet coating platform 6, and a group of anode sheets are placed in the placement groove of the anode sheet coating platform 6, then the mechanical mounting plate 14 drives the four groups of manipulator assemblies to move to the left, at this time, the first stacking manipulator assembly 11 moves to directly above the anode sheet coating platform 6, and the cylinder thereon drives the suction cup and the pushing frame 16 to move downward, during this process, the pushing frame 16 squeezes the connecting frame 17 downward, so that the connecting frame 17 drives the vertical push bar 18 to move downward, and the toggle column 19 on the vertical push bar 18 acts on the inclined slot 21, so that the transverse moving plate 20 is forced to squeeze the reset spring 22 and drive the cylindrical pin 23 toward away from the square moving frame The cylindrical pin 23 acts on the wheel groove of the cylindrical cam 24, so that the cylindrical cam 24 is driven by the force to rotate the clockwise rotating shaft 25 180°, so that the end of the eccentric wheel 26 first contacts the left side wall of the square moving frame 27 and then contacts the upper end wall, and the square moving frame 27 acts on the glue box 30 by acting on the connecting block 28 and the limit frame 29, and the limit frame 29 performs a linear motion up and down in the glue coating table, so that the two adjacent groups of glue boxes 30 first move together in the direction away from the placement groove and then move longitudinally in opposite directions, so that the second glue roller 32 first presses against the upper and lower sides of the edge of the anode sheet for horizontal coating and then releases and moves away; then the first stacking robot assembly 11 takes out the anode sheet coated with glue and attaches it to the bottom diaphragm cloth, and the second stacking robot assembly 13 takes out the cathode sheet coated with glue and attaches it to the second diaphragm cloth, and so on, to obtain a lithium battery cell with a fixed structure and a flat surface.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
