Description

Technical Field

[0001] The invention relates to the technical field of conveying for battery processing, in particular to a conveying device for producing and processing lithium electronic batteries. Background Art

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. In the production process of lithium-ion batteries, it is usually necessary to first apply the pre-prepared positive and negative electrode coatings on the surface of aluminum foil or copper foil through a coating device, and after the coating is completed, the coated positive and negative electrode coils are rolled by a rolling device, so that the positive and negative electrode coatings are tightly attached to the aluminum foil or copper foil, and the rolled positive and negative electrode coils can be used as positive and negative electrodes inside lithium-ion batteries after subsequent processing.

[0003] During the coating process, the positive and negative electrode coatings will adhere to debris due to static electricity, and it will be difficult to remove the debris adhered to the positive and negative electrode coatings after the subsequent rolling. Ultimately, more impurities will exist on the finished lithium-ion battery, affecting the normal use and service life of the lithium-ion battery. In addition, since the positive and negative electrode coatings just coated are not tightly attached to the aluminum foil or copper foil, the positive and negative electrode coatings are very likely to fall off during the process of transporting the positive and negative electrode coils from the coating device to the rolling device, thereby interrupting the production process of the lithium-ion battery. If the positive and negative electrode coatings are pre-laminated during the transportation of the positive and negative electrode coils, since the aluminum foil or copper foil has strong ductility, the lamination method using the laminating roller can only make the aluminum foil or copper foil extend, rather than laminating the positive and negative electrode coatings to fit the aluminum foil or copper foil.

DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0027] See also Figure 1 A conveying device for the production and processing of lithium electronic batteries includes a collection base plate 1, vertical plates 11 are symmetrically fixed to the top of the collection base plate 1, a pressing mechanism 2 is installed between the two vertical plates 11, and a cleaning mechanism 4, a corrective pressing mechanism 3 and a power assembly 12 are arranged on the top of the collection base plate 1 from left to right, and the corrective pressing mechanism 3 is located below the pressing mechanism 2.

[0028] The present invention corrects the coated positive and negative electrode coils and pre-presses the positive and negative electrode coatings through the pressing mechanism 2 in cooperation with the correcting pressing mechanism 3, so that the positive and negative electrode coatings can be adhered to the surface of the aluminum foil or the copper foil, and the aluminum foil or the copper foil is corrected, thereby avoiding the subsequent rolling of the positive and negative electrode coils to press the wrinkled aluminum foil or the copper foil and cause it to fold. In addition, it can also prevent the positive and negative electrode coatings from falling off due to loose fitting during the transportation process, and the cleaning mechanism 4 can remove the debris adhered to the surface of the positive and negative electrode coatings during the coating process, and ensure the normal use of the finished lithium-ion battery.

[0029] Specifically, the coated positive and negative electrode coils are first driven to move to the right by the power component 12, and then the debris adhered to the surface of the positive and negative electrode coatings is cleaned by the cleaning mechanism 4, and then the positive and negative electrode coils are pressed and shaped by the corrective pressing mechanism 3 in cooperation with the pressing mechanism 2, so as to avoid wrinkles in the positive and negative electrode coils, and prevent the positive and negative electrode coatings from falling off the surface of the aluminum foil or copper foil by pressing the positive and negative electrode coatings.

[0030] See also Figure 1 and Figure 5 The power assembly 12 includes a mounting column 121 symmetrically fixed on the top of the assembly bottom plate 1. Power rollers 122 distributed up and down are rotatably mounted between the two mounting columns 121. A power motor 123 is mounted on the front side of the front mounting column 121 corresponding to the position of each power roller 122 through a motor box. The output end of each power motor 123 passes through the front mounting column 121 and is connected to the power roller 122. The power assembly 12 is used to provide power for the positive and negative electrode coils to move to the right, and at the same time, it can press the positive and negative electrode coatings and make them fit tightly on the surface of the aluminum foil or copper foil. Specifically, firstly, the two power motors 123 are controlled to drive the upper and lower power rollers 122 to rotate counterclockwise and clockwise respectively, so that the power rollers 122 drive the positive and negative electrode coils to move to the right.

[0031] See also Figure 1-Figure 3 The cleaning mechanism 4 includes multiple groups of vertical sleeves 41 fixed on the top of the assembly bottom plate 1. The multiple groups of vertical sleeves 41 are evenly distributed in a horizontal linear manner. Each group of vertical sleeves 41 is composed of vertical sleeves 41 that are symmetrically distributed front and back with the horizontal slide rail 31 as the symmetry axis. Each group of vertical sleeves 41 is provided with an upper member 42. A blow-off member 43 is provided on the top of the assembly bottom plate 1 and behind all the upper members 42. The cleaning mechanism 4 is used to clean the debris adhered to the positive and negative electrode coatings during the coating process. The upper member 42 is mainly used to push the positive and negative electrode coils upward in multiple places so that the positive and negative electrode coils are corrugated. Then, the positive and negative electrode coating surfaces on the upper surfaces of the positive and negative electrode coils are blown by the blow-off member 43, so as to clean the debris adhered to the positive and negative electrode coating surfaces.

[0032] Specifically, after the power roller 122 drives the positive and negative electrode coils to move to the right, the positive and negative electrode coils will first contact the upper top component 42, and then the upper top component 42 will be controlled to push the positive and negative electrode coils upward, and the positive and negative electrode coils will appear corrugated. At the same time, the upper top component 42 will drive the blowing component 43 to move upward synchronously, and control the blowing component 43 to blow away the debris adhered to the positive and negative electrode coatings on the upper surface of the positive and negative electrode coils during the upward movement of the positive and negative electrode coils.

[0033] See also Figure 2-Figure 4 The upper supporting member 42 includes an embedded rod 421 slidably connected to the vertical sleeve 41 through a vertical spring, an upper supporting roller 422 is fixed between the two embedded rods 421 corresponding to the front and rear positions, and avoidance grooves are provided on the opposite sides of the two vertical sleeves 41 corresponding to the front and rear positions, and a supporting rod 423 is fixed between the two embedded rods 421 corresponding to the front and rear positions and below the upper supporting roller 422; a mounting plate 440 is fixed to the top of the collective bottom plate 1, a cylinder 441 is installed on the left side of the mounting plate 440, and a horizontal moving plate 442 is fixed to the pushing end of the cylinder 441, and the horizontal moving plate 442 is horizontally moved on the top of the collective bottom plate 1 through a mounting block installed with a rolling ball, and a plurality of trapezoidal blocks 443 corresponding to the supporting rods 423 are fixed on the top of the horizontal moving plate 442, and the distance between the trapezoidal blocks 443 and the supporting rods 423 on the right side increases from right to left.

[0034] The upper supporting member 42 is used to lift the positive and negative electrode coils upward, and by means of different distances between the trapezoidal block 443 and the supporting rod 423 it lifts, the upper supporting roller 422 moves upward in sequence and lifts the positive and negative electrode coils, thereby achieving the purpose of making the positive and negative electrode coils present a corrugated shape, and the method of lifting the positive and negative electrode coils upward by the supporting rod 423 can also make the debris adhered to the positive and negative electrode coatings on the upper surfaces of the positive and negative electrode coils separate from the positive and negative electrode coatings in advance, thereby facilitating the blowing-off member 43 to blow off the debris.

[0035] See also Figure 1-Figure 4 The blowing-off component 43 includes a mounting rod 431 which is fixed to the rear side of each rear embedded rod 421, an upper extension plate 432 is fixed to the rear end of the mounting rod 431, an output nozzle 433 is hinged to the top of the upper extension plate 432, and a torsion spring for maintaining the longitudinal air supply of the output nozzle 433 and the upper extension plate 432 is arranged at the hinge of the output nozzle 433 and the upper extension plate 432; a positioning plate 434 is fixed to the top of the collective bottom plate 1 and is located at the rear side of all the upper top components 42, a blower 435 is installed on the front side of the positioning plate 434, the blower 435 is connected to the output nozzle 433 through a plurality of air supply pipes 436, and a forward-inclined resisting rod 437 is fixed to the top of the output nozzle 433; a vertical rod 438 is fixed to the right side of each rear vertical sleeve 41, and a blocking plate 439 for resisting the resisting rod 437 is fixed to the top of the vertical rod 438.

[0036] The blowing-off component 43 is used to blow off the debris adhered to the positive and negative electrode coatings on the upper surface of the positive and negative electrode coils, mainly by outputting gas through the output nozzle 433, so as to blow off the debris that has been separated from the positive and negative electrode coatings in advance, and at the same time, the output nozzle 433 can also move upward with the upper roller 422, and in the process of the output nozzle 433 moving upward, the blocking plate 439 will press the resisting rod 437 and make the output nozzle 433 rotate forward and downward, and then the output nozzle 433 will tilt from top to bottom and blow off the debris more effectively along the corrugated peak position formed by the positive and negative electrode coils.

[0037] Specifically, when the positive and negative electrode coils are in contact with the upper supporting member 42, the control cylinder 441 drives the horizontal moving plate 442 to move back and forth left and right. As the horizontal moving plate 442 moves back and forth left and right, all the trapezoidal blocks 443 will first move to the right and move back and forth left and right. At the same time, the blower 435 is controlled to output the airflow to the output nozzle 433 through the air supply pipe 436, and the airflow is sprayed out by the output nozzle 433, so as to blow off the debris adhered to the positive and negative electrode coatings on the upper surface of the positive and negative electrode coils. In the process of reciprocating left and right movement, all the trapezoidal blocks 443 will first lift the supporting rod 423 upward from right to left in sequence. As the supporting rod 423 moves upward, it will drive the embedded rod 421 and the upper supporting roller 422 to move upward synchronously. Moreover, since the upper supporting roller 422 is pushed up from right to left in sequence, the positive and negative electrode coils will appear corrugated under the top pressure of the upper supporting roller 422.

[0038] During the upward movement of the embedded rod 421, the output nozzle 433 will move upward with the embedded rod 421. When the embedded rod 421 moves up to a certain height, the resisting rod 437 will be pressed by the blocking plate 439 to drive the output nozzle 433 to rotate forward and downward. At this time, the output nozzle 433 at the corrugated peak of the positive and negative electrode coils will just rotate forward and downward, so that the output nozzle 433 can be tilted from top to bottom and blow off the debris more effectively along the corrugated peak position formed by the positive and negative electrode coils.

[0039] See also Figure 5-Figure 6 The orthopedic pressing mechanism 3 includes a horizontal slide rail 31 fixed on the top of the collective base plate 1, and a vertical column 311 is slidably connected to the horizontal slide rail 31 through an electric slider. A longitudinal plate 312 is fixed on the top of the vertical column 311, and a vertical movable plate 313 is slidably connected to the top of the longitudinal plate 312. An orthopedic component 32 is arranged on the top of the vertical movable plate 313; a pushing component 35 cooperating with the movable pressing component 22 is arranged on the front side of the longitudinal plate 312.

[0040] See also Figure 5 , Figure 6 and Fig. 9 The pressing mechanism 2 includes a pressing cylinder 21 fixed between two vertical plates 11, a lower groove 211 is opened in the middle of the pressing cylinder 21, and a movable pressing member 22 is longitudinally slidably connected in the lower groove 211; the movable pressing member 22 includes a longitudinal slide 221 which is arranged in the middle of the pressing cylinder 21 and corresponds to the position of the lower groove 211, the rear end of the longitudinal slide 221 is connected to the vertical plate 11 on the rear side through a No. 1 elastic telescopic rod 222, a plurality of No. 2 elastic telescopic round rods are longitudinally and uniformly fixed to the bottom of the longitudinal slide 221, a mounting seat 223 is fixed to the telescopic end of the No. 2 elastic telescopic round rod, and a ball 224 is arranged at the bottom of the mounting seat 223; a pushed block 225 of the pushed member 35 is fixed to the front end of the longitudinal slide 221.

[0041] See also Figure 5 , Figure 6 and Figure 8 The pushing member 35 includes an L-shaped connecting rod 351 fixed to the front side of the longitudinal plate 312, a horizontal slider 352 is fixed to the top of the vertical section of the L-shaped connecting rod 351, a horizontal column 354 is fixed to the top of the horizontal slider 352 through a fixing plate 353, and a plurality of pushing protrusions 355 for pushing the pushed block 225 are uniformly arranged horizontally and linearly on the rear side of the horizontal column 354; a stabilizing slide rail 356 is fixed to the rear side of the vertical plate 11 on the front side, and the horizontal slider 352 slides horizontally on the stabilizing slide rail 356.

[0042] The corrective pressing mechanism 3 is used to cooperate with the pressing mechanism 2 to correct the positive and negative electrode coils so that the positive and negative electrode coils are flat, and the pressing mechanism 2 can cooperate with the corrective pressing mechanism 3 to press the positive and negative electrode coatings on the upper surfaces of the positive and negative electrode coils, so that the positive and negative electrode coatings are more closely attached to the aluminum foil or copper foil, thereby preventing the positive and negative electrode coatings from falling during transportation and affecting the subsequent processing of the positive and negative electrode coils. In addition, the pressing effect of the pressing mechanism 2 on the positive and negative electrode coatings can be increased by moving the pressing component 22, and the pressing cylinder 21 can assist in pressing the positive and negative electrode coatings when the corrective component 32 corrects the positive and negative electrode coils.

[0043] Specifically, when the positive and negative electrode coils continue to move to the right from the position of the cleaning mechanism 4, the positive and negative electrode coils will move to the position between the pressing mechanism 2 and the orthopedic pressing mechanism 3. At this time, the electric slider is controlled to drive the vertical column 311 and the longitudinal plate 312 to move back and forth, and the orthopedic component 32 will correct the positive and negative electrode coils. At the same time, the horizontal column 354 will move back and forth with the longitudinal plate 312. When the pushing protrusion 355 contacts the pushed block 225, the pushing protrusion 355 will push the pushed block 225 and the longitudinal plate 312. When the pushing protrusion 355 is separated from the pushed block 225, the longitudinal slide 221 will move forward due to the elastic force of the No. 1 elastic telescopic rod 222, so that the longitudinal slide 221 will reciprocate back and forth during the contact between the pushing protrusion 355 and the pushed block 225. During this process, the ball 224 will continue to press the positive and negative electrode coatings, and the corrective component 32 will support the bottom of the positive and negative electrode coils during this process, thereby ensuring the pressing effect of the ball 224.

[0044] See also Figure 6-Figure 8 The orthopedic component 32 includes a rotating frame 321 hinged on the top of the vertical movable plate 313, and an orthopedic roller 322 is rotatably installed on the end of the rotating frame 321 away from the top of the vertical movable plate 313. A spring plate 323 is fixed on the rotating frame 321, and a compression spring 324 is connected between the spring plate 323 and the top of the vertical movable plate 313. Track rods 325 are symmetrically fixed to the vertical movable plate 313 at the front and back; track plates 326 for cooperating with the track rod 325 to drive the vertical movable plate 313 to move up and down are symmetrically fixed on the front and back sides of the pressure cylinder 21.

[0045] The corrective component 32 is used to correct the positive and negative electrode coils, which is mainly achieved by the corrective roller 322 pressing the positive and negative electrode coils upward. At the same time, the pressure spring 324 can automatically adjust the upward pressure of the corrective roller 322, so that the corrective roller 322 automatically adjusts the pressure on the positive and negative electrode coils during the upward movement due to the cooperation between the track rod 325 and the track plate 326, thereby increasing the corrective effect on the positive and negative electrode coils.

[0046] Specifically, in the process of the electric slider driving the vertical column 311 and the longitudinal plate 312 to move back and forth left and right, the vertical movable plate 313 will reciprocate left and right together with the longitudinal plate 312, and the corrective roller 322 will continue to press the positive and negative electrode coils upward, and cooperate with the limiting action of the pressure cylinder 21 and the ball 224 to correct the positive and negative electrode coils. When the vertical movable plate 313 moves to the left, the track rod 325 will move upward due to the action of the track plate 326, and drive the vertical movable plate 313 to move upward, thereby driving the rotating frame 321 and the corrective roller 322 to move upward, and the corrective roller 322 will further press the positive and negative electrode coils upward, thereby more effectively correcting the positive and negative electrode coils.

[0047] See also Figure 5 , Figure 6 and Figure 8 The orthopedic pressing mechanism 3 also includes two groups of fixed columns 314 fixed to the top of the assembly bottom plate 1 symmetrically with the pressing cylinder 21 as the axis, each group of fixed columns 314 is composed of two fixed columns 314 symmetrically with the horizontal slide rail 31 as the axis, each group of fixed columns 314 is rotatably mounted with a longitudinal limiting roller 315, each group of fixed columns 314 is rotatably mounted with an arc-shaped pressing plate 316 located below the longitudinal limiting roller 315, and a transmission mechanism No. 1 is connected between the arc-shaped pressing plates 316 on the left and right sides and the longitudinal plate 312 respectively. Part 33 and No. 2 transmission component 34; No. 1 transmission component 33 includes a square telescopic rod 331 fixed at the lower end of the rotation position of the arc-shaped pressure plate 316 on the left side, and an L-shaped left extension rod 332 is fixed to the bottom of the longitudinal plate 312, and the left end of the horizontal section of the L-shaped left extension rod 332 is connected to the telescopic end of the square telescopic rod 331; No. 2 transmission component 34 includes a connecting rod 341 symmetrically hinged on the right side of the longitudinal plate 312, and the end of the connecting rod 341 away from the longitudinal plate 312 is hinged above the rotation position of the arc-shaped pressure plate 316 on the right side.

[0048] By cooperating with the arc-shaped pressure plate 316 through the longitudinal limiting roller 315, the positive and negative electrode coils can be further corrected, and the arc-shaped pressure plate 316 can pass through the No. 1 transmission component 33 and the No. 2 transmission component 34, and with the left and right reciprocating motion of the corrective component 32, the positive and negative electrode coils can be pushed inward or stretched outward synchronously, thereby cooperating with the compression spring 324 to achieve the purpose of increasing the corrective effect on the positive and negative electrode coils.

[0049] Specifically, when the vertical movable plate 313 moves to the left, the L-shaped left extension rod 332 will move to the left along with the longitudinal plate 312. At this time, the square telescopic rod 331 will shrink while being pushed by the L-shaped left extension rod 332 to drive the arc-shaped pressing plate 316 on the left to rotate to the right, and the right connecting rod 341 will directly drive the arc-shaped pressing plate 316 on the right to rotate to the left, thereby pushing the positive and negative electrode coils to the position of the corrective component 32. Although the arc-shaped pressing plate 316 on the right cannot be pushed directly to the left, The positive and negative electrode coils can be slowed down to move to the right by the corrective member 32, so as to cooperate with the corrective member 32 to fully stretch and correct the aluminum foil or copper foil. When the vertical moving plate 313 moves to the right, the arc-shaped pressure plates 316 on both sides will be due to the action of the No. 1 transmission member 33 and the No. 2 transmission member 34, so that the positive and negative electrode coils at the position of the corrective member 32 are pushed away from the corrective member 32, thereby ensuring that the positive and negative electrode coils are straightened and increasing the corrective effect of the corrective member 32 on the positive and negative electrode coils.

[0050] The working steps of the present invention are as follows: the first step is to control the two power motors 123 to drive the upper and lower power rollers 122 to rotate counterclockwise and clockwise respectively, so that the power rollers 122 drive the positive and negative electrode coils to move to the right, and the positive and negative electrode coils will move from the cleaning mechanism 4, the corrective pressing mechanism 3 and the pressing mechanism 2 in turn.

[0051] In the second step, after the power roller 122 drives the positive and negative electrode coils to move to the right, the positive and negative electrode coils will first contact the upper top member 42, and then the upper top member 42 will be controlled to push the positive and negative electrode coils upward, and the positive and negative electrode coils will appear corrugated. At the same time, the upper top member 42 will drive the blowing component 43 to move upward synchronously, and control the blowing component 43 to blow away the debris adhered to the positive and negative electrode coatings on the upper surface of the positive and negative electrode coils during the upward movement of the positive and negative electrode coils.

[0052] In the third step, when the positive and negative electrode coils continue to move to the right from the position of the cleaning mechanism 4, the positive and negative electrode coils will move to the position between the pressing mechanism 2 and the corrective pressing mechanism 3. At this time, the electric slider is controlled to drive the vertical column 311 and the longitudinal plate 312 to move back and forth left and right. At this time, the pushing member 35 will push the moving pressing member 22 to perform longitudinal reciprocating motion, thereby pressing the positive and negative electrode coatings on the upper surface of the positive and negative electrode coils.

[0053] In the fourth step, while the electric slider drives the vertical column 311 and the longitudinal plate 312 to move back and forth left and right, the vertical movable plate 313 will move back and forth left and right together with the longitudinal plate 312, and the corrective roller 322 will continue to press the positive and negative electrode coils upward, and cooperate with the limiting effect of the pressure cylinder 21 and the ball 224 to correct the positive and negative electrode coils. When the vertical movable plate 313 moves to the left, the track rod 325 will move upward due to the action of the track plate 326, and drive the vertical movable plate 313 to move upward, thereby driving the rotating frame 321 and the corrective roller 322 to move upward, so that the corrective roller 322 corrects the positive and negative electrode coils by pressing upward.

[0054] In the fifth step, when the vertical movable plate 313 moves back and forth to the left and right, the arc-shaped pressure plates 316 on both sides will push the positive and negative electrode coils at the position of the corrective component 32 towards or away from the corrective component 32 due to the action of the No. 1 transmission component 33 and the No. 2 transmission component 34, thereby increasing the corrective effect of the corrective component 32 on the positive and negative electrode coils.

A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still within the scope of protection of the present invention.
