DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0031] Example 1

[0032] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0033] like Figures 1 to 9 As shown, a workshop environmentally friendly lithium battery electrode anti-deformation drying equipment includes a support frame 1, a transmission component 2 and a swing component 3 driven by the transmission component 2 are provided on the support frame 1, the transmission component 2 includes a transmission belt 21 rotatably arranged on both sides of the support frame 1 for transmitting the electrode 4, a drying component 5 is provided below the transmission belt 21, the drying component 5 includes a plurality of drying hoods 51, and an adjustment component 6 is provided on the drying hood 51. The drying component 5 dries the electrode 4 through the drying hood 51, the swing component 3 is used to drive the drying hood 51 to swing back and forth, and the adjustment component 6 is used to adjust the wind force of the drying hood 51, wherein an air suction hood is provided above the transmission belt 21 and the air suction hood is connected to an exhaust device to suck air when blowing and drying the electrode 4.

[0034] It is worth mentioning that Figure 4 As shown, the transmission component 2 also includes a fixed frame 22 fixedly arranged below the support frame 1, an active tooth 23 and a passive tooth 24 fixedly arranged on the shaft of the transmission belt 21, the active tooth 23 is engaged with the passive tooth 24, and the rotation of the transmission belt 21 is arranged between the support frame 1 and the fixed frame 22, wherein a motor is fixedly arranged on the support frame 1, and the output shaft of the motor is connected to the shaft of the transmission belt 21 on one side, thereby driving the transmission belt 21 to rotate. When in use, a manual or robotic arm places the pole piece 4 between the two transmission belts 21, and the transmission belt 21 clamps the pole ear on the pole piece 4 and transmits it, and dries it during the transmission process to improve the drying effect of the pole piece 4.

[0035] In addition, if Figure 6 and Figure 7 As shown, the drying assembly 5 also includes a rotating shaft 53 rotatably arranged on the fixed frame 22, the rotating shaft 53 is fixedly connected to the side walls of the drying cover 51 on both sides, and several drying covers 51 are fixedly connected to each other. When in use, the electrode 4 is dried by the hot air ejected from the drying cover 51 during transportation.

[0036] It should be emphasized that if Figure 6 and Figure 7As shown, the swing assembly 3 includes a rotating shaft 31 rotatably set on the fixed frame 22, a first bevel gear 32 fixedly set on the rotating shaft 31, a guide cylinder 33 rotatably set on the fixed frame 22, a guide groove 34 provided on the guide cylinder 33, a second bevel gear 35 fixedly set on the guide cylinder 33, a slide groove 36 provided on the fixed frame 22, a rack 37 slidably set in the slide groove 36, a guide rod 38 fixedly set on the rack 37, and a gear 39 fixedly set on the rotating shaft 53. The rack 37 is meshed with the gear 39. The bottom of the guide rod 38 is set to a spherical shape and cooperates with the guide groove 34. The first bevel gear 32 is meshed with the second bevel gear 35. Pulleys are provided on the axis of the transmission belt 21 and the rotating shaft 31. The pulleys are connected by belts. When in use, when the transmission belt 21 is transmitting, it drives the rotating shaft 31 to rotate, drives the first bevel gear 32, the second bevel gear 35, and the guide cylinder 33 to rotate, thereby driving the rack 37 to move back and forth, driving the gears 39 on both sides to rotate at the same time and the rotation directions are always opposite, so that the drying hoods 51 on both sides swing at the same time and the swing directions are consistent, so that the hot air can fully dry the pole piece 4 during the swing. The drying hood 51 is placed at the bottom of the pole piece 4, and blows air at an angle to the pole piece 4. The inclined blowing method makes the area of the hot air contacting the pole piece 4 wider. Since the hot air always flows upward, the hot air is always concentrated and fully contacts the pole piece 4, achieving a better drying effect.

[0037] It should be further explained that if Figure 8 and Figure 9As shown, the regulating component 6 includes an air pipe 61 fixedly arranged on the drying cover 51, an electromagnetic valve 62 fixedly arranged on the air pipe 61, a sensing rod 63 fixedly arranged under the conveyor belt 21, a proximity switch 64 fixedly arranged on the sensing rod 63, and a signal receiver 65 fixedly arranged on the drying cover 51. The proximity switch 64 is electrically connected to the signal receiver 65, and the signal receiver 65 is electrically connected to the electromagnetic valve 62. An air pump is connected to the air pipe 61 and an electric heating wire is provided on the air pipe 61 to heat the gas. A single proximity switch 64 on a single sensing rod 63 is electrically connected to a single signal receiver 65 on the drying cover 51 on the opposite side. The distance between the proximity switches 64 on the opposite sides and the electrode 4 is set to be the same. When the electrode 4 changes When the shape causes the pole piece 4 to tilt and offset, the distance between the two proximity switches 64 and the pole piece 4 is inconsistent. At this time, the wind force is adjusted by the signal receiver 65 and the solenoid valve 62 to keep the pole piece 4 in a horizontal state at all times. When in use, the pole piece 4 is transmitted between the two sensing rods 63. When the wind forces in the drying hoods 51 on both sides are inconsistent, the wind force on one side is strong, which blows the pole piece 4 to an angle, causing the pole piece 4 to contact the proximity switch 64 on the opposite sensing rod 63. At this time, the proximity switch 64 transmits an electrical signal to the signal receiver 65 on the side with strong wind force. The signal receiver 65 transmits an electrical signal to the solenoid valve 62. The solenoid valve 62 reduces the wind force in the drying hood 51, so that the wind force on both sides is always balanced, thereby preventing the pole piece 4 from deforming during drying.

[0038] It is worth mentioning that Figure 4 As shown, the conveyor belt 21 is made of rubber material and has a rough surface. The rubber material prevents the pole ears from being worn, and the rough surface can prevent the pole pieces 4 from falling off.

[0039] Further, such as Figure 5 As shown, the guide groove 34 is configured as a wave-shaped groove structure.

[0040] In addition, if Figure 5 As shown, the cross section of the drying cover 51 is set to be trapezoidal to improve the drying effect.

[0041] Working process

[0042] A manual or mechanical hand places the electrode 4 between the two conveyor belts 21 for transmission, while the electrode 4 is located between the two sensing rods 63. Then, an air pump sends gas through the air pipe 61 and the drying hood 51 to dry the electrode 4. The axis of the conveyor belt 21 rotates, driving the guide cylinder 33 to rotate. The guide cylinder 33 drives the rack 37 to slide back and forth, driving the two gears 39 to rotate, causing the drying hoods 51 on both sides to swing simultaneously and in the same direction, drying the electrode 4. When the wind force in the drying hoods 51 on both sides is inconsistent, resulting in a stronger wind force on one side, the electrode 4 is blown to a side, causing the electrode 4 to contact the proximity switch 64 on the opposite sensing rod 63. At this time, the proximity switch 64 transmits an electrical signal to the signal receiver 65 on the side with stronger wind force. The signal receiver 65 transmits an electrical signal to the solenoid valve 62. The solenoid valve 62 reduces the wind force in the drying hood 51, so that the wind force on both sides is always balanced, preventing the electrode 4 from deforming during drying.
