In an embodiment, the material turning assembly 500 is located above the material conveying assembly 200, the material turning assembly 500 further includes an elastic member 530, the material turning member 520 is connected to the rotating member 510 through the elastic member 530, the elastic member 530 is configured to apply an elastic force to the material turning member 520 along a direction away from the rotating member 510, and when the material turning member 520 rotates to a side of the rotating member 510 facing the material conveying assembly 200, the material turning member 520 can be abutted against the material conveying assembly 200. When the turning piece 510 drives the turning piece 520 to rotate to one side facing the material conveying assembly 200, the elastic piece 530 can enable the turning piece 520 to contact with the material conveying assembly 200 at a certain rotation angle, so that the amount of battery materials scooped up by the turning piece 520 is increased, and the turning effect is improved. For example, when the material turning piece 520 is 5 degrees to 20 degrees from the vertical, the material turning piece 520 may contact the material conveying assembly 200. In other embodiments, the material mover 520 contacts the material delivery assembly 200 when the material mover 520 is at other angles to the vertical.
In this embodiment, the elastic member 530 may be an elastic structure such as a spring or a spring plate, so long as the material turning member 520 can be guaranteed to contact with the material conveying assembly 200 at a certain rotation angle.

After the battery material is overturned by the overturning assembly and poured on the material conveying assembly 200, the material conveying assembly 200 drives the battery material to pass through the scraping assembly, the overturned battery material can be scraped on the material conveying assembly 200 by the scraping assembly, the contact area of the battery material with ozone and ultraviolet light is further improved, and the battery material is prevented from being stacked on the material conveying assembly 200 after being overturned.
In one embodiment, the screeding assembly may include a squeegee vertically disposed above the material delivery assembly 200 and having a gap with the material delivery assembly 200. In other embodiments, the screeding assembly may comprise a roller disposed above the material conveying assembly 200 with a gap between an outer surface of the roller and the material conveying assembly 200, the axis of rotation of the roller intersecting the conveying direction a.

The number of uv light source assemblies 300 corresponds to the number of material transport assemblies 200, and each uv light source assembly 300 is configured to emit uv light toward a corresponding material transport assembly 200.
Because the aging of the battery material requires a certain time, and the material conveying assembly 200 is in the process of the production line, the material conveying assembly 200 needs to be started to continuously convey the battery material, and the material conveying assembly 200 needs a certain length to meet the aging time requirement of the battery material. By providing at least two material conveying assemblies 200, on the one hand, it is advantageous to reduce the length of a single material conveying assembly 200, and thus to facilitate a compact arrangement of the structure. On the other hand, if only one material handling assembly 200 is provided, ozone enters from one end of the material handling assembly 200 and flows along the length of the material handling assembly 200 to the other end, resulting in a greater concentration variation of ozone along the length of the material handling assembly 200. In this embodiment, the material conveying assembly 200 is arranged in at least two, the length of the single material conveying assembly 200 is shortened, and the distance from one end of the material conveying assembly 200 to the other end is shortened, so that the ozone concentration in the aging cavity 110 is more uniform, and oxidation of battery materials is facilitated. In this embodiment, the material turning assembly 500 is disposed at the joint between two material conveying assemblies 200, and the battery material is turned during the process of transferring from one material conveying assembly 200 to another material conveying assembly 200, so that not only the turning effect can be improved, but also the turning assembly can directly contact and rub with the material conveying assemblies 200, and the structural stability of the material conveying assemblies 200 is ensured.
For example, in this embodiment, the number of the material conveying assemblies 200 is three, the three material conveying assemblies 200 are arranged up and down at intervals, the number of the material turning assemblies 500 is two, and the two material turning assemblies 500 are respectively arranged at the connection positions of the two material conveying assemblies 200, so that two material turning can be realized. In other embodiments, the number of material handling assemblies 200 may be two, four, etc. as well.
In this embodiment, the scraping assembly is disposed behind the feeding end of the material conveying assembly 200 below, and a gap is formed between the scraping assembly and the corresponding material conveying assembly 200. When battery material falls behind the material loading end of material conveying assembly 200 of below by material conveying assembly 200 of top, material conveying assembly 200 of below drives battery material and scrapes the subassembly through scraping, utilizes and scrapes the subassembly and can scrape the battery material after overturning on material conveying assembly 200, avoids battery material to pile up on material conveying assembly 200.
In an embodiment, the material turning assembly 500 further includes a receiving hopper 540, one end opening of the receiving hopper 540 is abutted to the discharging end of the material conveying assembly 200 located above, the other end opening of the receiving hopper 540 is abutted to the feeding end of the material conveying assembly 200 located below, and the rotating member 510 and the material turning member 520 are both disposed in the receiving hopper 540. Through setting up the receiving hopper 540, can make the battery material flow to the material loading end of the material conveying assembly 200 that is located the below behind the stirring piece 520 effectively, guarantee battery material stirring and stability of forwarding.
Specifically, the receiving hopper 540 includes a curved baffle 542 and a receiving portion 544, the concave surface of the curved baffle 542 faces the discharging end of the upper material conveying assembly 200, and one side edge of the curved baffle 542 is located above the discharging end of the material conveying assembly 200, the other side edge is connected to the receiving portion 544, an opening above the receiving portion 544 is communicated with one side of the concave surface of the curved baffle 542, the cross-sectional dimension of the space in the receiving portion 544 tends to be reduced from top to bottom, and the rotating member 510 and the turning member 520 are both disposed in the receiving portion 544. By providing the arcuate baffle 542, it is possible to ensure that the battery material dropped from the discharge end of the upper material handling assembly 200 effectively falls into the receiving portion 544 and that the material turning member 520 does not turn the battery material out of the receiving hopper 540 when rotated. While the cross-sectional size of the space within the receiving portion 544 tends to decrease from top to bottom, ensuring the reliability of the battery material falling on the loading end of the lower material handling assembly 200.
In one embodiment, as shown in fig. 1, the air inlet 120 is disposed near the feeding end of the material conveying assembly 200, and the air outlet 130 is disposed near the feeding end of the material conveying assembly 200, so that the flowing direction b of ozone in the aging chamber 110 is opposite to the conveying direction a. By reversing the flow direction b of ozone in the aging chamber 110 to the transport direction a of the battery material, the battery material having a higher temperature after heating can be reacted with ozone having a higher concentration. At higher temperature, ozone can be rapidly decomposed into oxygen and active oxygen, and active oxygen atoms have strong oxidation, so that more effective and strong oxidation reaction can be generated with the binder with higher temperature, and the aging speed of the binder is improved. At the loading end of the material conveying assembly 200, the temperature of the battery material is relatively low, so that the ozone concentration is increased, on the one hand, the ozone decomposition effect is poor, and on the other hand, the oxidation reaction effect of the battery material at a lower temperature is also poor.
In another embodiment, as shown in fig. 4, the air inlet 120 is provided near the discharge end of the uppermost material handling assembly 200, and the air outlet 130 is provided near the feed end of the uppermost material handling assembly 200. Specifically, the number of the air inlets 120 and the air outlets 130 may be identical to the number of the material conveying assemblies 200, and the plurality of air inlets 120 and the air outlets 130 are arranged at intervals along the vertical direction, so that the stable ozone can circulate above each material conveying assembly 200.
As shown in fig. 1, in an embodiment, the uv light source assembly 300 includes a first uv light source 310 and at least two second uv light sources 320, the first uv light source 310 is configured to emit uv light with a wavelength of 170nm-200nm, the second uv light source 320 is configured to emit uv light with a wavelength of 250nm-400nm, all the second uv light sources 320 are disposed at intervals along the conveying direction a, and the first uv light source 310 is disposed between two adjacent second uv light sources 320. Because ozone generates oxygen and active oxygen atoms after decomposition, the concentration of ozone tends to decrease along the flowing direction b of ozone, and the concentration of oxygen increases as the reaction proceeds, oxygen can be further converted into ozone under the ultraviolet light of 170nm-200nm wavelength emitted by the first ultraviolet light source 310, so as to increase the concentration of ozone, and ozone can be further decomposed to obtain oxygen and active oxygen atoms under the ultraviolet light of 250nm-400nm wavelength emitted by the second ultraviolet light source 320. With the progress of the oxidation reaction, the concentration of ozone and the effect of the oxidation reaction can be effectively improved by arranging the second ultraviolet light source 320, the first ultraviolet light source 310 and the second ultraviolet light source 320 to sequentially and alternately decompose and generate ozone.
Specifically, the first ultraviolet light source 310 is configured to emit ultraviolet light having a wavelength of 185 nm. Or the first ultraviolet light source 310 may emit ultraviolet light at other wavelengths effective to promote ozone generation.
Specifically, the second ultraviolet light source 320 is configured to emit ultraviolet light having a wavelength of 300nm to 400nm, and at this wavelength, the second ultraviolet light source 320 can effectively promote photooxidation reaction of the adhesive, and at the same time has an effect of decomposing ozone. Alternatively, the second ultraviolet light source 320 is configured to emit ultraviolet light having a wavelength of 250nm to 300nm, at which the second ultraviolet light source 320 is capable of effectively promoting decomposition of ozone while simultaneously achieving photooxidation of the adhesive. In this embodiment, the binder is PVDF (polyvinylidene fluoride) and the second ultraviolet light source 320 is configured to emit ultraviolet light at a wavelength of 370 nm. In other embodiments, the wavelength emitted by the second ultraviolet light source 320 may also be selected based on the band of ultraviolet light to which the adhesive is susceptible to aging.
In the present embodiment, the length of the second ultraviolet light source 320 tends to increase along the conveying direction a. Since the concentration of ozone tends to increase along the conveying direction a, the length of the second uv light source 320 is increased at the position of the material conveying assembly 200 at or near the discharging end, which can increase the distance of the reaction of ozone decomposition oxidation and increase the effect of the second uv light source 320 on the photo-oxidation reaction of the binder. As the concentration of ozone decreases, the length of the second uv light source 320 needs to be decreased, increasing the number or length of the first uv light sources 310, and thus increasing the generation of ozone.
In this embodiment, the length of the second ultraviolet light source 320 is longer than that of the first ultraviolet light source 310, so as to ensure the photooxidation effect and the ozonolysis oxidation effect.
As shown in fig. 4, in this embodiment, when the number of the material transporting assemblies 200 is at least two and the number of the ultraviolet light source assemblies 300 is identical to the number of the material transporting assemblies 200, the length of the second ultraviolet light source 320 tends to decrease in the circulation direction b of ozone. As the concentration of ozone decreases, the length of the second uv light source 320 needs to be decreased, increasing the number or length of the first uv light sources 310, and thus increasing the generation of ozone.
In an embodiment, if the second uv light source 320 is a strip lamp, the length of the second uv light source 320 is the length of the strip lamp, and if the second uv light source 320 is composed of a plurality of lamp beads, the length of the second uv light source 320 is the arrangement length of the plurality of lamp beads.
Referring to fig. 1 and 4, in one embodiment, the battery material aging mechanism 10 further includes a heating element 600, the heating element 600 is disposed in the aging chamber 110, and the heating element 600 is used for heating the material conveying element 200.
Ozone can be rapidly decomposed into oxygen and active oxygen, and active oxygen atoms have strong oxidation effect and can be combined with unsaturated bonds in the adhesive, so that the molecular chains of the adhesive are broken in the combining stage, and the ageing of the high-molecular adhesive is caused. The adhesive will change in two ways after being heated: one is physical change, the thermoplastic resin with a linear structure is expressed as rotation and melting, and the thermosetting resin is expressed as larger deformation under the action of external force; the other is chemical change, which is mainly represented by thermal decomposition, and oxygen is generated in the oxidation reaction process due to ozone, and the binder is promoted to be simultaneously subjected to oxidative cleavage in the thermal decomposition state. Under the condition of heating and oxygen-containing, the binder is easier to generate photochemical reaction under ultraviolet light, the ultraviolet light can trigger the binder to generate photochemical reaction so that molecular chains are decomposed and crosslinked irreversibly to generate chemical change, and if chain decomposition is dominant, the binder can be softened; if crosslinking predominates, the binder becomes brittle. The aging mechanism 10 for battery material is enhanced by the mutual promotion of ozone, ultraviolet light and heat, so that the effect of using the three materials independently is achieved. In the embodiment, the method of accelerating the aging of the adhesive by ultraviolet irradiation in the ozone environment can improve the crushing and separation efficiency of the electrode material to more than 95%.
In this embodiment, the heating temperature of the heating element 600 may be lower than the heating temperature of the battery material aging mechanism 10 alone by using only the heating element 600, so that the same or better aging effect can be achieved.
As shown in fig. 1 and 4, in an embodiment, the heating assembly 600 includes a first heater 610 and at least two second heaters 620, all the second heaters 620 are disposed at intervals along the conveying direction a of the material conveying assembly 200, the first heater 610 is disposed between two adjacent second heaters 620, and the position of the first heater 610 corresponds to the position of the first uv light source 310, and the position of each second heater 620 corresponds to the position of one second uv light source 320. Under the heating condition, the decomposition of ozone can be promoted, so that the effect of promoting the oxidative aging of the adhesive can be ensured by keeping the second heater 620 on at the position corresponding to the second ultraviolet light source 320, and the generation of ozone by promoting oxygen is required at the position corresponding to the first ultraviolet light source 310, so that the first heater 610 can be selected to be turned off, so that the temperature of the position corresponding to the first ultraviolet light source 310 can be properly reduced, and the generation of ozone can be promoted.
In this embodiment, the material conveying assembly 200 includes a conveying belt 210, a driving wheel 220 and a driven wheel 230, the conveying belt 210 is wound around the driving wheel 220 and the driven wheel 230, the heating assembly 600 is disposed between the driving wheel 220 and the driven wheel 230 and between the upper conveying belt 210 and the lower conveying belt 210, and the first heater 610 and the second heater 620 are arranged along the length direction of the conveying belt 210. Since the battery material is placed on the upper conveyor belt 210, the distance between the first heater 610 and the second heater 620 and the battery material can be shortened by providing the first heater 610 and the second heater 620 between the upper conveyor belt 210 and the lower conveyor belt 210, and the heating effect on the battery material can be improved.

Because the uv light source assembly 300 is disposed in the aging chamber 110, and the heating assembly 600 is used for heating the aging chamber 110, the uv light source assembly 300 is affected by the heat of the uv light source assembly 300, and the temperature of the uv light source assembly 300 is high, which affects the stability of use. By providing the cooling assembly 800 to cool the uv light source assembly 300, the reliability of the use of the uv light source assembly 300 can be improved.
Specifically, cooling assembly 800 is further disposed on ozone generator 400 and is configured to cool ozone generator 400.

When the cooling device is used, the relatively hot cooling medium subjected to heat exchange by the cooling unit 810 enters the heat exchanger 820, and part of heat of the cooling medium can be absorbed by ozone discharged from the heat exchanger 820 and enters the aging cavity 110, so that heat recovery after heat exchange of the cooling medium is realized. The cooling medium passing through the heat exchanger 820 is cooled by the heat pump assembly 700 and then enters the cooling unit 810 again to cool the ultraviolet light source assembly 300 and the ozone generator 400. By providing the heat exchanger 820, heat recovery is effectively achieved, energy consumption in the aging chamber 110 is reduced, and energy consumption of the heat pump assembly 700 is reduced.
In the present embodiment, the heat exchanger 820 is disposed near the air inlet 120 of the aging oven 100. Because ozone is easily decomposed after being heated, so that the heated ozone can enter the aging cavity 110 at a short distance, the oxidation effect of the ozone decomposed active oxygen is ensured.
In one embodiment, the cooling unit 810 includes a first cooler 812 and a second cooler 814, the first cooler 812 and the second cooler 814 are connected in parallel in the cooling medium circulation loop, wherein the first cooler 812 is disposed on a sidewall of the aging oven 100 where the uv light source assembly 300 is disposed, and the second cooler 814 is disposed adjacent to the first cooler 812 and is mounted on the ozone generator 400.
