DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] like Figure 2 and Figure 3 As shown, the vibration mechanism 2 includes a vibration box 201, a vibration motor 202, a buffer spring 203 and a discharge port 204. The vibration box 201 is located in the middle of the two side frames 1, the vibration motor 202 is fixedly arranged on one side of the vibration box 201, the buffer spring 203 is fixedly arranged on both sides of the vibration box 201 and connected to the frame 1 through a connecting seat, and the discharge port 204 is opened on one side of the vibration box 201. All the batteries to be coated are placed in the vibration box 201, and the batteries are randomly arranged in the vibration box 201. The vibration motor 202 works, driving the vibration box 201 to shake continuously as a whole, and the batteries are discharged from the discharge port 204, and the disordered batteries are converted to be placed horizontally, which is convenient for subsequent coating work.

[0031] like Figure 2 and Figure 3 As shown, the actuator 3 includes a guide shaft 301, a copper sleeve 302, a connecting plate 303, a first spring 304, a bearing seat 305 and a roller 306. The guide shaft 301 is arranged at the top of the frame 1, the copper sleeve 302 is fixedly arranged at the bottom side of the top of the frame 1, and the guide shaft 301 and the copper sleeve 302 are threadedly connected. The connecting plate 303 is rotatably connected to the bottom end of the guide shaft 301, the first spring 304 is sleeved on the guide shaft 301, the bearing seat 305 is fixedly arranged on the connecting plate 303, and the roller 306 is rotatably installed between the bearing seats 305 on both sides. The film coating roller is installed on the roller 306. According to the different sizes of the batteries, the guide shaft 301 is rotated to drive the connecting plate 303 and the roller 306 to move up and down to adjust the distance between the roller 306 and the battery, so as to achieve the purpose of adapting to the coating of batteries of different sizes.

[0032] like Figure 2 and Figure 3As shown, the driving assembly 4 includes a reduction motor 401, a pulley 402, a connecting belt 403, a conveying roller 404 and a conveying belt 405. The reduction motor 401 is fixedly arranged at one end of the frame 1, and the pulley 402 is matched and installed at the output end of the reduction motor 401, and the number of the pulleys 402 is two groups, the connecting belt 403 is installed on the two groups of pulleys 402, the conveying roller 404 is installed on the frame 1 through a rotating seat, and the conveying belt 405 is installed on the conveying rollers 404 at both ends. The reduction motor 401 works to drive one group of pulleys 402 to rotate, and then drives the other group of pulleys 402 to rotate through the connecting belt 403, thereby driving the conveying belt 405 to operate through the conveying roller 404, and the batteries are conveyed in an assembly line manner.

[0033] like Figure 2 As shown, a collecting bin 5 is fixedly arranged between the racks 1, and the collecting bin 5 is located at the end of the conveyor belt 405. The batteries that have been coated are collected in the collecting bin 5.

[0034] like Figure 1 As shown, two groups of lighting lamps 6 are fixedly installed between the tops of the frame 1, and the lighting lamps 6 are electrically connected to an external power supply. The lighting lamps 6 facilitate operation during the laminating process.

[0035] like Figure 2 As shown, the surface of the conveyor belt 405 is evenly provided with multiple groups of grooves 7, which are used to place cylindrical batteries, and the batteries move along the conveyor belt in the grooves 7. The batteries are limited in position in the grooves 7, and one battery corresponds to one groove 7 to keep the position of the battery stable.

[0036] like Figure 6 As shown, elastic limiting components are installed at both ends of the groove 7 for limiting and fixing batteries of different lengths. The elastic limiting components are composed of a sliding sleeve 702, a spring 703 and an inner rod 701. The spring 703 is sleeved in the inner rod 701, and the sliding sleeve 702 slides in the inner rod 701. The spring 703 limits the sliding of the sliding sleeve 702. The inner rod 701 is fixed on both ends of the groove 7. The two ends of the battery squeeze the sliding sleeve 702, thereby fixing the battery, and the battery can roll on the sliding sleeve 702. A turntable connected to a bearing can also be set at the end of the sliding sleeve 702. When the battery is against the rotatable turntable, the battery can rotate with the turntable.

The coating roller is installed on the roller 306. Since the battery is coated for one circle, after the first group of actuators 3 coats the upper half of the battery, the friction between the battery and the coating roller can drive the battery to rotate half a circle in the groove 7, and the second group of actuators 3 continues to coat the remaining half circle.

[0038] Specifically, when the lithium iron phosphate battery coating protection device is working: the coating roller is installed on the roller 306, and according to the different sizes of the batteries, the guide shaft 301 is rotated to drive the connecting plate 303 and the roller 306 to move up and down to adjust the distance between the roller 306 and the batteries, and all the batteries to be coated are placed in the vibration box 201, and the batteries are randomly arranged in the vibration box 201. The vibration motor 202 works to drive the vibration box 201 to shake continuously as a whole, and the batteries are discharged from the discharge port 204, and the disordered batteries are converted to be placed horizontally and fall into the groove 7. In the process, the reduction motor 401 works to drive one set of pulleys 402 to rotate, and then drives the other set of pulleys 402 to rotate through the connecting belt 403, thereby driving the conveyor belt 405 to operate through the conveyor roller 404, and the batteries are conveyed in an assembly line manner. After the first set of actuators 3 coats the upper half of the battery, the friction between the battery and the coating roller can just drive the battery to rotate half a circle in the groove 7, and the second set of actuators 3 continues to coat the remaining half circle. The coated batteries are collected in the collection bin 5.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways.
