DETAILED DESCRIPTION

[0008] The present invention will be further described in detail below with reference to the accompanying drawings.

[0009] like Figures 1 to 12 As shown, the structure and function of an electric vehicle battery manufacturing equipment are described in detail below; An electric vehicle battery manufacturing device includes a slurry box 12. Two right sliding seats 21 are slidably connected to the side of the slurry box 12. The two sliding seats 21 are fixedly connected to a telescopic mechanism I 22. The telescopic ends of the two telescopic mechanisms I 22 are fixedly connected to a telescopic mechanism II 23. The telescopic ends of the two telescopic mechanisms II 23 are fixedly connected to a smear bracket 24. The two smear brackets 24 are each provided with a cyclically moving smear belt 41. The two smear belts 41 are staggered. When using, Figure 1 As shown, the electrode slurry is placed in the slurry box 12, and the sliding seat 21 is pushed to slide on the side of the slurry box 12. The sliding seat 21 drives the telescopic mechanism I 22 to move, the telescopic mechanism I 22 drives the telescopic mechanism II 23 to move, the telescopic mechanism II 23 drives the smear bracket 24 to move, and the smear bracket 24 drives the smear belt 41 to move, thereby adjusting the mutual distance between the two smear belts 41; Start the telescopic mechanism I 22, which can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 22 drives the telescopic mechanism II 23 to move. The telescopic mechanism II 23 drives the smear bracket 24 to move. The smear bracket 24 drives the smear belt 41 to move, thereby adjusting the relative distance between the smear belt 41 and the electrode belt, and thus adjusting the smear thickness. Furthermore, the telescopic mechanism II 23 is activated. The telescopic mechanism II 23 may be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 23 drives the smear bracket 24 to move. The smear bracket 24 drives the smear belt 41 to move, thereby adjusting the width of the two smear belts 41, and thereby adjusting the total length of the two smear belts 41 when they are in contact with the electrode belt, thereby adjusting the width of the smear on the electrode belt. Furthermore, in order to facilitate the lateral movement of the sliding seat 21, the slurry box 12 is fixedly connected to the device bracket 11. The front and rear ends of the device bracket 11 are rotatably connected to the limiting rollers 13. An electrode belt passes between the limiting rollers 13 and the two smear belts 41. The height of the electrode belt is limited by the two limiting rollers 13 so that the electrode belt can only pass between the limiting rollers 13 and the two smear belts 41. The slurry box 12 is rotatably connected to two screw rods 14, and the slurry box 12 is fixedly connected to a power mechanism I for driving the screw rods 14 to rotate, and two sliding seats 21 are respectively connected to the two screw rods 14 through threads; Start the power mechanism I, which is preferably a servo electrode. The output shaft of the power mechanism I starts to rotate, and the output shaft of the power mechanism I drives the screw 14 to rotate. When the screw 14 rotates, it drives the sliding seat 21 to move through the thread. The sliding seat 21 drives the telescopic mechanism I 22 to move. The telescopic mechanism I 22 drives the telescopic mechanism II 23 to move. The telescopic mechanism II 23 drives the smear bracket 24 to move. The smear bracket 24 drives the smear belt 41 to move, thereby adjusting the mutual distance between the two smear belts 41. Furthermore, in order to make the slurry applied on the electrode tape uniform; The smear bracket 24 is rotatably connected to two driving rollers 25, and the smear bracket 24 is fixedly connected to a power mechanism II for driving the driving rollers 25 to rotate. The bottom of the smear bracket 24 is slidably connected to two telescopic seats 26, and a compression spring is fixedly connected between the telescopic seats 26 and the smear bracket 24. A lifting roller 27 is rotatably connected between the two telescopic seats 26; The smear bracket 24 is fixedly connected to a telescopic mechanism III 31, and a swing motor 32 is fixedly connected to the telescopic end of the telescopic mechanism III 31. A swing bracket 33 is fixedly connected to the output shaft of the swing motor 32. A plurality of support rollers 34 are rotatably connected to the swing bracket 33. The smear belt 41 is wrapped around the outer sides of the plurality of support rollers 34, the two driving rollers 25 and the lifting roller 27. Start the power mechanism II, and the output shaft of the power mechanism II begins to rotate. The output shaft of the power mechanism II drives the driving roller 25 to rotate. When the driving roller 25 rotates, it drives the smear belt 41 to move, so that the movement direction of the smear belt 41 is opposite to the movement direction of the electrode belt, that is, in the process of driving the electrode belt to continuously move from one side to the other side, such as from left to right, the smear belt 41 is also continuously moved under the drive of the driving roller 25, so that the smear belt 41 continuously moves from right to left, so that relative movement is generated between the smear belt 41 and the electrode belt, and the lower end of the smear belt 41 is continuously in contact with the slurry in the slurry box 12, so that the smear belt 41 continuously drives the slurry to move and smear on the electrode belt; Furthermore, the telescopic mechanism III 31 is started. The telescopic mechanism III 31 may be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 31 drives the swing motor 32 to move. The swing motor 32 drives the swing bracket 33 to move. The swing bracket 33 drives the smear belt 41 to move, thereby adjusting the height of the smear belt 41 located on the upper side. At the same time, the swing motor 32 is started. The output shaft of the swing motor 32 drives the swing bracket 33 to move. The swing bracket 33 drives the multiple support rollers 34 to move, so that the multiple support rollers 34 are tilted, thereby tilting the upper end of the smear belt 41. That is, if the electrode belt continuously moves from left to right, the height of the right end of the smear belt 41 is greater than the height of the left end of the smear belt 41, forming a slope, thereby achieving a gradual smearing effect, and controlling the thickness of the slurry smeared on the electrode belt; Furthermore, in order to mix the slurry and continuously push the slurry into the slurry box 12, the slurry in the slurry box 12 is kept at a level height; The bottom of the slurry box 12 is fixedly connected to a push cylinder 51, a feed pipe 52 is fixedly connected to the push cylinder 51, a rotating ring 53 is rotatably connected to the push cylinder 51, a drive motor 54 is fixedly connected to the push cylinder 51, a screw shaft 55 is fixedly connected to the output shaft of the drive motor 54, the screw shaft 55 is rotatably connected to the rotating ring 53, and the screw shaft 55 passes through the rotating ring 53 and is located in the push cylinder 51; The slurry is put into the pushing cylinder 51 through the feeding pipe 52, and the driving motor 54 is started. The output shaft of the driving motor 54 starts to rotate, and the output shaft of the driving motor 54 drives the screw shaft 55 to rotate. When the screw shaft 55 rotates, a lateral driving force is generated, which continuously pushes the slurry into the slurry box 12; Furthermore, in order to continuously mix and stir the slurry in the pushing cylinder 51; The screw shaft 55 is rotatably connected to a plurality of stirring rods 56, each stirring rod 56 is fixedly connected to a gear 57, and the push barrel 51 is rotatably connected to a ring gear 59, and the plurality of gears 57 are meshed with the ring gear 59 for transmission. The push barrel 51 is fixedly connected to a power mechanism III for driving the ring gear 59 to rotate, and each stirring rod 56 is fixedly connected to a plurality of stirring impellers 58; During the rotation of the spiral shaft 55, the stirring column 56 is driven to rotate, and the stirring column 56 drives the multiple stirring impellers 58 thereon to rotate, thereby mixing and stirring the slurry in the pushing barrel 51. Due to the continuous movement of the coating belt 41, the slurry is continuously coated on the electrode belt, and the coating thickness and coating width of the coating belt 41 are controlled, so that the slurry descending speed in the slurry box 12 will change. In order to ensure that the slurry in the slurry box 12 is always at a stable height, it is necessary to control the rotation speed of the output shaft of the drive motor 54, and then control the rotation speed of the spiral shaft 55. At this time, in order to ensure the mixing effect, the power mechanism III is started, and the output shaft of the power mechanism III starts to rotate. The output shaft of the power mechanism III drives the ring gear 59 to rotate, and the ring gear 59 drives multiple gears 57 to rotate. The gear 57 drives the stirring column 56 to rotate, and the stirring column 56 drives the stirring impeller 58 to rotate, thereby accelerating or slowing down the rotation of the stirring impeller 58 to ensure the mixing effect of the stirring impeller 58 on the slurry; Furthermore, since the slurry has a certain viscosity, and when the position adjustment of the smear belt 41 is completed, the position of the smear belt 41 will be fixed, and the continuous circulation of the smear belt 41 will drive the slurry in the slurry box 12 in the fixed position, which may cause the upper end of the slurry in the slurry box 12 to be uneven. Therefore, the spiral shaft 55 is fixedly connected to a groove pulley I 61, and two groove pulleys II 62 are rotatably connected in the slurry box 12. The groove pulley I 61 and the two groove pulleys II 62 are connected by a homogenizing belt 63. The inner side of the homogenizing belt 63 is fixedly connected to a plurality of ridges, which can be inserted into the grooves provided on the groove pulley I 61 and the groove pulley II 62. Then, when the spiral shaft 55 rotates, it drives the groove pulley I 61 to rotate, and the groove pulley I 61 drives the homogenizing belt 63 to continuously move, and the homogenizing belt 63 continuously drives the slurry in the slurry box 12 to flow, so that the slurry in the slurry box 12 is in a flowing state, ensuring that the upper end of the slurry in the slurry box 12 is in a horizontal state, ensuring that the smear belt 41 can contact a specified amount of slurry; A process for manufacturing an electric vehicle battery, comprising the following steps: Step 1: Place the mixed electrode coating slurry in the slurry box 12; put the slurry into the pushing cylinder 51 through the feeding pipe 52, start the driving motor 54, and the output shaft of the driving motor 54 starts to rotate, which drives the screw shaft 55 to rotate. When the screw shaft 55 rotates, it generates a lateral driving force to continuously push the slurry into the slurry box 12; Step 2: Pass the electrode tape to be coated through the upper side of the two coating tapes 41; limit the height of the electrode tape by two limiting rollers 13 so that the electrode tape can only pass between the limiting rollers 13 and the two coating tapes 41; Step 3: Adjust the relative distance between the two smear belts 41 and the electrode, and the two smear belts 41 move in a circular motion to smear the slurry on the electrode belt; An electric vehicle battery uses two coating belts 41 to coat slurry on an electrode belt; the movement direction of the coating belt 41 is opposite to the movement direction of the electrode belt, that is, in the process of driving the electrode belt to continuously move from one side to the other, such as from left to right, the coating belt 41 is also continuously moved under the drive of the driving roller 25, so that the coating belt 41 continuously moves from right to left, so that relative movement is generated between the coating belt 41 and the electrode belt, the lower end of the coating belt 41 is continuously in contact with the slurry in the slurry box 12, and then the coating belt 41 continuously drives the slurry to move and coat the electrode belt.
