The effective combination of materials and metal current collectors is not only related to the electrochemical performance of the equipment, but also directly affects the life and safety of the equipment.

[0003] There are two main technologies for transferring traditional materials to metal current collectors. The first is to use a screw extruder to extrude the material into a film, and then roll-press the film-forming electrode and the current collector.

[0004] The second technology is electrostatic spraying. Under the action of the electrostatic spray gun, the powder is given a negative charge and sprayed onto the positively charged metal foil current collector. This method can achieve rapid material transfer and can control the distribution of materials to a certain extent. However, the electrostatic spraying process has high requirements for equipment, resulting in higher production and processing costs for batteries, and the uniformity of the material paving on the metal foil current collector is also low.

[0044] Figures 1 to 4 The material metering device 10 in some embodiments of the utility model is shown, and the material metering device 10 is used to attach materials to materials such as material belts or other types of materials. The material metering device 10 includes a material drop component 1 and a material distribution component 2, and the material distribution component 2 is arranged on the material drop component 1. It can be understood that the material drop component 1 plays a role in carrying materials. The material distribution component 2 is used to evenly distribute the materials and then discharge them.

[0045] like Figures 2 to 5 As shown, the blanking assembly 1 includes a material seat 11 and a scraper 12. The material seat 11 is provided with a blanking channel 111, and a material dividing position 112 is provided in the blanking channel 111 (the material dividing position 112 is shown in FIG. Figure 5 ), the scraper 12 is arranged on the material seat 11, and at least a part of the scraper 12 is exposed at the material dividing position 112.

[0046] It can be understood that the material holder 11 is used to store materials, and the materials can be powder or other types of materials, which vary depending on the application field, processing and manufacturing requirements or other processing requirements. The scraper 12 is used to scrape off excess materials so that the materials can be evenly distributed to various positions on the material distribution component 2. The material drop channel 111 is used to guide the material to move along a predetermined direction or a predetermined trajectory, and the material distribution position 112 refers to the position where the material moving along the material drop channel 111 can be blocked to prevent the material from being discharged directly without delay and without uniform distribution.

[0047] like Figures 3 to 6As shown, the material dividing assembly 2 includes a driving member 21 and a material dividing roller 22. The driving member 21 is arranged on the material seat 11, and the driving member 21 is connected to the material dividing roller 22. The material dividing roller 22 is provided with a plurality of accommodating grooves 221 on the peripheral side surface. The material dividing roller 22 is rotatably arranged at the material dividing position 112, and the scraper 12 is held against the peripheral side surface of the material dividing roller 22, so that the material moving along the material dropping channel 111 can be blocked by the material dividing roller 22 and the scraper 12.

[0048] The driving member 21 is configured to drive the material distribution roller 22 to rotate, so that the materials can fall into each receiving groove 221 one by one, and the scraping member 12 can scrape off the materials outside the receiving groove 221, so that the materials can fall out through each receiving groove 221.

[0049] It can be understood that the driving member 21 is used to output torque to the material distribution roller 22, so that the material distribution roller 22 rotates. The material distribution roller 22 is used to complete the uniform distribution and uniform processing of materials during the rotation process. The number of the accommodating grooves 221 is configured to be multiple, and the multiple accommodating grooves 221 are evenly arranged along the rotation direction of the material distribution roller 22, that is, the intervals between two adjacent accommodating grooves 221 are configured to be equal. The accommodating grooves 221 are used to accommodate materials.

[0050] In the actual production and processing process, the material can enter through one end of the blanking channel 111, so that the material moves along the blanking channel 111. When the material moves to the material distribution position 112, it will be blocked by the scraper 12 and the material distribution roller 22 and cannot continue to move. That is, the material will accumulate between the material distribution position 112 and the end of the blanking channel 111 for the material to enter;

[0051] The driving member 21 drives the material distribution roller 22 to rotate. During the rotation of the material distribution roller 22, each of the receiving grooves 221 on the material distribution roller 22 will face the side of the material delivery channel 111 one by one, so that the material will fill each of the receiving grooves 221 one by one. With the rotation of the material distribution roller 22, on the one hand, each of the receiving grooves 221 will also drive the material to rotate together. On the other hand, since the scraper 12 always abuts against the surface of the material distribution roller 22, the scraper 12 will scrape off the material outside the receiving groove 221 on the material distribution roller 22, so that only the material in the receiving groove 221 can pass through the material distribution position 112.

[0052] As the material distribution roller 22 rotates, each of the receiving grooves 221 will rotate one by one to a position in the material drop channel 111 for the material to fall out. After the material falls out of the receiving groove 221, it will further fall and be discharged to the outside of the material holder 1, so that the material can be attached to the material belt or some other materials, thereby achieving the purpose of attaching one material to another material through the material metering device 10.

[0053] In summary, the utility model can load materials or attach them to predetermined positions only by rotating the material distribution roller 22, without the need for complex mechanical structures or parts in the related art, thereby reducing the cost of the overall equipment and improving the production and processing efficiency of the product;

[0054] On the other hand, by opening the blanking channel 111 and setting the scraper 12, not only can the material be evenly distributed in the accommodating groove 221, that is, the material can be evenly distributed to the peripheral side of the dividing roller 22, but the material can also be evenly blanked and discharged, thereby improving the processing uniformity of the material.

[0055] Only the material in the accommodating groove 221 can be dropped when the dividing roller 22 rotates, thereby preventing the excess material on the side of the dividing roller 22 from crossing the dividing position 112 and dropping under the drive of the dividing roller 22, thereby improving the uniformity of material distribution.

[0056] like Figure 5 and Figure 6 As shown, in some embodiments of the material metering device 10, a feed trough 113 and a discharge channel 114 are also provided on the material seat 11 along the material dropping direction D, the feed trough 113 and the discharge channel 114 are interconnected to form the material dropping channel 111, and the material dividing position 112 is located at the connection position between the feed trough 113 and the discharge channel 114; the feed trough 113 is used for material introduction, and the discharge channel 114 is used for the material falling out of the accommodating groove 221 to be further discharged to the outside of the material seat 11.

[0057] It is understandable that the groove wall profile of the feed trough 113 can be flexibly set and adjusted according to the material processing requirements. The discharge channel 114 is used for the corresponding discharge of the material to the outside of the material holder 11. After the material enters through the feed trough 113, it will be blocked at the material distribution position 112, that is, the material cannot directly pass through the material distribution position 112 to enter the discharge channel 114 and be discharged.

[0058] It should be noted that the inner wall profile and inner wall size of the material discharge channel 114 can be flexibly set, as long as the material falling out of the accommodating groove 221 can be smoothly discharged to the predetermined position for processing.

[0059] like Figure 5 As shown, in some embodiments of the material metering device 10 , the width of the feed trough 113 gradually increases in a direction away from the dividing roller 22 , so that a material guiding slope 1131 is formed on the trough wall of the feed trough 113 .

[0060] It can be understood that, along the material falling direction D, any two positions are taken in the feed trough 113, and the widths of the feed trough 113 at the two positions are W1 and W2 respectively, wherein the distance between the position corresponding to W1 and the material distribution position 112 is greater than the distance between the position corresponding to W2 and the material distribution position 112, and W1>W2.

[0061] It should be noted that the material guiding slope 1131 may be provided only on the trough wall on one side of the material feeding trough 113 , or the material guiding slope 1131 may be provided on both trough walls of the material feeding trough 113 .

[0062] like Figure 5 and Figure 6 As shown, in some embodiments of the material metering device 10, the material blanking assembly 1 includes two scrapers 12, both of which are located on the material seat 11, and the two scrapers 12 are symmetrically arranged on both sides of the dividing roller 22, and both of the scrapers 12 are supported on the peripheral side of the dividing roller 22.

[0063] It can be understood that the provision of the two scrapers 12 can, on the one hand, more effectively prevent the material from passing through the outer side of the periphery of the dividing roller 22, and effectively block the material at the dividing position 112; on the other hand, one of the scrapers 12 can scrape off the excess material outside the receiving groove 221 after the receiving groove 221 is filled with material, and the other scraper 12 can scrape off the material accidentally remaining on the side of the periphery of the dividing roller 22 during the material dropping process, so that the material in each receiving groove 221 can fall out as fully as possible, thereby further improving the uniformity of material processing.

[0064] like Figure 5 As shown, in some embodiments of the material metering device 10 , a scraping end 121 is provided on the scraping member 12 , and the thickness of the scraping end 121 gradually decreases in a direction approaching the dividing roller 22 .

[0065] It can be understood that, taking any two positions on the scraper end 121 in the direction close to the material distribution roller 22, the thickness of the scraper end 121 at the two positions is T1 and T2 respectively, wherein the distance between the position corresponding to T1 and the material distribution roller 22 is smaller than the distance between the position corresponding to T2 and the material distribution roller 22, and T1<T2. In this way, the cross section of the scraper end 121 will be triangular or substantially triangular, and the triangular or substantially triangular shape can improve the scraping effect of the scraper end 121 on the material distribution roller 22, and scrape as much material as possible except for the material located in the receiving groove 221 on the side of the circumference of the material distribution roller 22, thereby further improving the material processing uniformity of the equipment.

[0066] like Figure 1 and Figure 2As shown, in some embodiments of the material metering device 10, the material metering device 10 further includes a positioning component 3, and the positioning component 3 is used to fix the scraper 12. It should be noted that if the number of the scraper 12 is configured as multiple, the number of the positioning components 3 is also correspondingly set to multiple, and the number of the positioning components 3 is preferably configured to be equal to the number of the scraper 12, so that each scraper 12 is correspondingly fixed by a positioning component 3, and the relative position of the scraper 12 and the material distribution roller 22 is kept fixed as much as possible.

[0067] like Figure 2 , Figure 4 and Figure 5 As shown, the positioning assembly 3 includes two positioning structures 31, each positioning structure 31 includes a plurality of positioning blocks 311 and a plurality of positioning bolts 312, each positioning block 311 is arranged on the material seat 11, each positioning bolt 312 is penetrated by the positioning block 311 and is screwed to the material seat 11, and each positioning block 311 clamps the scraper 12 together.

[0068] It can be understood that the two positioning structures 31 fix the scraper 12 from two opposite directions. The positioning block 311 is used to abut against the scraper 12, so as to be correspondingly supported on the scraper 12, so that the positioning blocks 311 of the two positioning structures 31 can clamp and fix the scraper 12 from two opposite sides. The positioning bolt 312 is used to fix the positioning block 311 on the material seat 11.

[0069] It should be noted that the number of positioning blocks 311 in each positioning structure 31 can be flexibly set, and the number of positioning blocks 311 in each positioning structure 31 can be configured to be equal or unequal.

[0070] like Figure 4 As shown, in some embodiments of the material metering device 10, a mounting groove 115 is provided on the material seat 11;

[0071] The material metering device 10 also includes a fixing component 4, which includes a fixing seat 41 and a fixing bolt 42. The fixing seat 41 is arranged in the installation groove 115. The fixing bolt 42 passes through the fixing seat 41 and is screwed to the material seat 11. The fixing seat 41 and the installation groove 115 jointly define a rotating hole 43, and the dividing roller 22 is rotatably arranged in the rotating hole 43.

[0072] It can be understood that the mounting groove 115 is used to install the fixing assembly 4. The fixing seat 41 is used to fix the material distribution roller 22 to the material support 11, so that the material distribution roller 22 can rotate on the material support 11. The number of fixing bolts 42 can be configured to be one or more, and it is preferred to be able to reliably fix the fixing seat 41 on the material support 11. The rotating hole 43 can be configured to be in direct contact with the material distribution roller 22, and can also be configured to be installed with a rotating bearing, and the material distribution roller 22 is supported by the rotating bearing to rotate on the material support 11.

[0073] like Figure 3 and Figure 5 As shown, in some embodiments of the material metering device 10 , the accommodating grooves 221 are evenly distributed along the circumferential direction of the dividing roller 22 .

[0074] It can be understood that the uniform distribution of the receiving grooves 221 means that the intervals between any two adjacent receiving grooves 221 are equal. In this way, after the dividing roller 22 rotates the same angle from any angle, the amount of material that can fall from the dividing roller 22 is as equal as possible.

[0075] In some embodiments of the material metering device 10 , the cross section of each accommodating groove 221 is triangular, quadrilateral or pentagonal.

[0076] It can be understood that the cross-sectional profile of the receiving groove 221 can be flexibly set, and preferably a profile that facilitates the material to fully fall out of the groove is adopted.

[0077] In some embodiments of the material metering device 10 , a material dividing Teflon layer is provided on the surface of the dividing roller 22 .

[0078] It can be understood that the provision of the material-distributing Teflon layer can reduce the friction between the material-distributing roller 22 and the inner wall surface of the material-distributing channel 111, reduce wear and tear, and prevent wear materials from mixing into the material.

[0079] It should be noted that the dividing Teflon layer is made of Teflon in the related technology; the dividing Teflon layer can be configured to be set on the dividing roller 22 by electroplating, and can also be configured to be pre-made of Teflon material and then assembled on the dividing roller 22, and can also be configured to be directly made of Teflon material to form part of the dividing roller 22 or the entire dividing roller 22.

[0080] In some embodiments of the material metering device 10 , a Teflon layer is provided on at least a portion of the inner wall surface of the material dropping channel 111 .

[0081] It can be understood that the blanking Teflon layer can reduce the wear of the inner wall surface of the blanking channel 111, avoid the mixing of wear materials into the material, and ensure the processing quality.

[0082] It should be noted that the blanking Teflon layer can be configured to be formed on the inner wall surface of the blanking channel 111 by electroplating, and can also be configured to be pre-made with Teflon and then assembled on the inner wall surface of the blanking channel 111.

[0083] In some embodiments of the material metering device 10 , at least a portion of the scraper member 12 is provided with a scraper Teflon layer.

[0084] It can be understood that the scraper Teflon layer can greatly reduce the friction between the scraper 12 and the material distribution roller 22, thereby avoiding excessive wear between the material distribution roller 22 that rotates for a long time and the scraper 12 that is always supported on the material distribution roller 22. Similarly, the capacity of the accommodating groove 221 can be prevented from changing due to wear, thereby ensuring the processing accuracy of the equipment.

[0085] It should be noted that the Teflon layer can be provided on the scraper 12 at a specific position for scraping off excess material, or the entire scraper 12 can be provided with the Teflon layer. Of course, the entire scraper 12 can also be directly made of Teflon material.

[0086] Figures 1 to 3 The battery production and processing equipment 20 in some embodiments of the utility model is shown, and the battery production and processing equipment 20 is used to produce batteries. The battery production and processing equipment 20 includes a machine platform, a feeding device 30 and a material metering device 10. The feeding device 30 includes two feeding rollers 40, and the two feeding rollers 40 are both rotatably arranged on the machine platform. The two feeding rollers 40 are both used to convey the material belt 50. The material seat 11 is located above the material belt, so that the material can fall onto the material belt after falling out through the accommodating groove 221.

[0087] It can be understood that the machine platform plays a role of fixed support. The feeding device 30 is used to transmit the material belt, which can be a current collector of the battery. The two feeding rollers 40 are respectively rotated and set at two different positions to achieve the purpose of conveying materials.

[0088] like Figure 2 As shown, in some embodiments, the material guided by the material metering device 10 and attached to the material belt 50 may be a powder material, and the powder material will form a current collecting outer layer 60 after being attached to the material belt 50 .

[0089] The implementation of this utility model has the following beneficial effects:

[0090] The utility model relates to a material metering device and a battery production and processing device. The battery production and processing device is provided with a material metering device. In the material metering device, when a driving member drives a material distribution roller to rotate, the material will fill each receiving groove on the material distribution roller accordingly, and a scraping member will scrape the material outside the receiving groove. Subsequently, along with the rotation of the material distribution roller, the material will fall out of each receiving groove one by one and be discharged to the outside of a material seat along a material dropping channel, so that the material is evenly attached to a material belt or other materials.

[0091] In this way, each receiving groove can only accommodate the same amount of material during the rotation process, so that the amount of material falling through each receiving groove per unit time is the same, thereby improving the uniformity of the material spreading; and the material transfer process can be completed only by the rotation of the dividing roller, which effectively improves the production and processing efficiency of the product, reduces the cost of the equipment, and thereby reduces the production and processing cost of the material.
