Description

TECHNICAL FIELD

[0001] The utility model relates to the field of lithium battery production, especially an automatic feeding mechanism. BACKGROUND

[0002] With the rapid development of lithium battery technology, dry electrode coating process is more and more widely used in battery production. Dry electrode coating process refers to mixing and stirring the positive and negative electrode materials, then laying them in the form of solid powder into a multi-roller rolling mechanism, and then forming a film through calendering. This process requires very high quality control of the materials, and the uniformity, fineness and film thickness of the powder directly affect the performance of the final electrode and the quality of the battery.

[0003] However, in the existing dry electrode coating equipment, many production lines still rely on manual feeding to complete the feeding of positive / negative electrode powder. This manual feeding method has many problems. First of all, it is inefficient, manual feeding is time-consuming and labor-intensive, and the feeding process is often not uniform and continuous, causing instability in the production process. In addition, manual feeding requires very high requirements for workers, who need to have rich experience to ensure the accuracy of feeding. On the other hand, the powder material is easy to fly during feeding, which leads to a decrease in air quality in the factory, workers may be exposed to harmful dust environment, which can easily cause occupational diseases, and these dusts may spread into the atmosphere, causing serious environmental pollution.

[0004] In addition, the mixed and stirred positive / negative electrode materials are often in the form of solid powder, and because the materials are easy to clump, they must be sieved through a screen to ensure uniform powder size and thus ensure the quality of the coating film. Existing manual operation can only rely on experience to judge the quality of the powder and the film formation, and lacks accurate quantitative measurement means, so it cannot effectively ensure the accuracy and stability of the coating, and thus affects the production quality of the dry electrode.

DETAILED DESCRIPTION

[0043] The utility model will be combined with the embodiment and the drawing to the conception, the specific structure and the technical effect of the utility model clear, complete description, to fully understand the purpose, characteristics and effect of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all embodiments, based on the embodiment of the utility model, the technical personnel in the art obtains other embodiments without paying creative labor, all belong to the protection scope of the utility model. In addition, all the coupling / connection relations involved in the patent, not single component direct interface, but can be according to the specific implementation situation, by adding or reducing the coupling auxiliary member, to constitute the better coupling structure. The various technical features in the utility model creation can be interactively combined under the premise of not mutually contradictory conflict.

[0044] In the dry electrode coating production, the positive / negative electrode powder material is manually fed, and the process includes powder material tray carrying, manual vibration screening through the screen 233, shovel collection of the screened powder material, and manual feeding. In this process, firstly, the feeding accuracy cannot be guaranteed, the manual feeding cannot be uniformly laid, and the continuous feeding cannot be realized, and the errors such as material breakage and material stacking cannot be avoided. The powder material is easy to fly into the air, causing poor air quality in the factory, which requires workers to wear strict protective measures to operate, and is prone to occupational diseases.

[0045] Based on the above problems, the automatic feeding mechanism of the utility model can solve the above problems. Referring to Figure 1 、 3 , 5, which comprises: a first frame body 100 provided with a hopper 110 for containing material; a separation mechanism 120 in communication with the hopper 110, the separation mechanism 120 is used for separating the material into multiple components and discharging through the first discharge port 121 at the bottom; a second frame body 200 is separately provided with the first frame body 100, and the second frame body 200 is provided with a conveying groove 210 located below the first discharge port 121 for receiving and conveying the material discharged through the first discharge port 121; a vibration mechanism 220 is arranged on the second frame body 200, and the vibration mechanism 220 is used to generate vibration in the conveying groove 210 to promote the conveying of the material along the conveying groove 210. It can be understood that the powder is prevented from flying by the hopper 110, the factory environment is ensured to be clean, and the threat to the health of workers is reduced. The feeding accuracy is improved by the quantitative feeding of the separation mechanism 120, the uniform and accurate conveying of the material is ensured, and the errors and instability caused by manual feeding are avoided. By vibration conveying, the manual carrying and shovel feeding work is replaced, the material can be continuously and stably conveyed, the problems such as material breakage and material stacking are avoided, and thus the production efficiency and electrode quality are improved.

[0046] Further, referring to Figure 1 、 2 , the cross section of the hopper 110 is V-shaped, which is a hollow inverted cone, a sealing cover 111 is arranged on the hopper 110, a feeding port 1111 is arranged on the sealing cover 111, a protective net 1112 is arranged in the feeding port 1111, and a cover plate 1113 is further arranged on the feeding port 1111. The sealing cover 111 cooperates with the hopper 110 to form a closed structure, which can effectively control the diffusion of dust, and when the inside of the hopper 110 needs to be cleaned and maintained, the sealing cover 111 can be easily taken out. Further, the cover plate 1113 is connected with the feeding port 1111 through a damping hinge, and the opening and closing operation is convenient.

[0047] In addition, referring to Figure 1 、 2The feeding port 1111 provided on the sealing cover 111 is used for feeding the material, and a protective net 1112 is arranged in the feeding port 1111 to prevent large-particle materials or foreign matters from entering the conveying system, to protect the quality of the material and the normal operation of the equipment, and to prevent the hand from being inserted to cause mechanical injury. A cover plate 1113 is further arranged on the feeding port 1111, which can effectively seal the feeding port 1111 to prevent the material from being blown out or leaked due to wind force or other external factors when the machine is stopped or not in use. At the same time, the cover plate 1113 can be quickly closed after the material is added, to ensure the sealing property of the material during the feeding process, and to avoid dust pollution and environmental pollution.

[0048] It should be noted that the capacity of the powder hopper 110 can be designed according to requirements. For example, if the positive electrode ternary material is used as the powder material, and the artificial feeding is required to be not more than 50 kg each time, and the material specific gravity is 3.4 g / cm 3 , or equivalent to 3.4 kg / L, then the capacity of the hopper 110 is required to be designed to be not more than 15 L.

[0049] In some embodiments, with reference to Figure 3 , 4 , the separating mechanism 120 includes a separating cavity 1201 and a separating wheel 1202 arranged in the separating cavity 1201, and the separating wheel 1202 is driven by a second driving motor 1203. After the material enters the separating cavity 1201, it is divided into multiple parts by the separating wheel 1202 and is discharged through a first discharge port 121. The separating wheel 1202 is designed according to requirements. For example, it is required to control the precision of the material dropping to be 50 g, that is, 0.1% of the maximum feeding weight, and the specific gravity of the powder material is 3.4 g / cm 3 , and it is calculated that the volume capacity of each interval of the separating wheel 1202 is 14.7 cm 3 , or not more than 15 mL. After the separating wheel 1202 is connected by the second driving motor 1203, the dropping of the powder material can be controlled with high precision. Specifically, a plurality of separating grooves are arranged at intervals on the separating wheel 1202, and the volume of a single separating groove and the weight of the material corresponding to the volume are set to control the precision of the discharge. The second driving motor 1203 can include a servo motor, a speed reducer, a shaft coupling, etc. The servo motor can provide higher control precision and stability, to ensure that the stirring part 1121 and the conveying system can realize precise speed and position control during the working process. Compared with ordinary motors, the servo motor has stronger dynamic response capability and higher torque density, which is particularly important for the material conveying and stirring process which requires high-precision control.

[0050] In some embodiments, with reference to Figure 1The weighing device 130 is arranged between the hopper 110 and the first frame body 100, and is used to detect the weight of the material in the hopper 110 in real time. By arranging the weighing device 130, the remaining amount of the material in the hopper 110 can be monitored in real time, so as to realize accurate material management and control. The weighing device 130 can provide real-time data feedback to the control system by accurately measuring the weight of the material in the hopper 110, so as to help determine whether the material has reached the predetermined conveying amount or weight, avoid excessive or insufficient feeding of the material, and ensure the accuracy of feeding.

[0051] In some embodiments, with reference to Figure 6 The arch-breaking mechanism 112 is arranged in the hopper 110, and the arch-breaking mechanism 112 includes a stirring part 1121. The stirring part 1121 is driven to rotate by a first driving motor 1122, so as to prevent the material from accumulating in the hopper 110. It can be understood that the arch-breaking mechanism 112 can effectively prevent the material from accumulating or condensing in the hopper 110 by dynamic stirring. The stirring part 1121 of the arch-breaking mechanism 112 can be optimized in different forms according to the characteristics of the material, such as spiral stirring, blade stirring, etc. The stirring part 1121 can be adjusted according to the flow characteristics of different materials. Specifically, with reference to Figure 6 、 7 The stirring part 1121 includes a connecting rod 1121a, a first stirring rod 1121b arranged at the end of the connecting rod and facing the inside of the hopper, and a second stirring rod 1121c facing the direction of the discharge port of the hopper. The first stirring rod 1121b is used to break the arch and stir the accumulated material in the hopper, so that the material is uniformly distributed and avoids accumulation and blockage. The second stirring rod 1121c is used to assist in pushing the material to move towards the discharge port of the hopper, so as to ensure smooth discharge. It should be noted that the first driving motor 1122 can include a servo motor, a speed reducer, a shaft coupling, etc.

[0052] Further, with reference to Figure 5 The vibration mechanism 220 is a device that can efficiently transmit vibration force and ensure the flowability of the material. It can be an electromagnetic vibrator, a mechanical vibrator, or a piezoelectric vibration device, etc. By arranging the vibration mechanism 220, the flowability of the material can be effectively improved, and the accumulation of the material in the conveying groove 210 can be reduced, so as to ensure the continuous operation of the production line. In addition, it should be noted that the equipment on the first frame body 100 does not need to vibrate, while the second frame body 200 is equipped with the vibration mechanism 220 and must continuously vibrate at high frequency. In order to prevent vibration from being transmitted to other mechanisms and causing resonance, thereby affecting the stability and high-precision operation of the equipment, the second frame body 200 and the first frame body 100 are designed in a split body. This split body arrangement can effectively isolate the vibration source, so as to ensure that the vibration is limited to the second frame body 200, and will not be transmitted to the first frame body 100 or other sensitive equipment, thereby avoiding system instability, precision loss or equipment failure caused by vibration.

[0053] In addition, the split structure of the second frame body 200 and the first frame body 100 can not only avoid the influence of vibration on the first frame body 100 device, but also provide better installation and debugging flexibility for the device. The non-vibration device configured on the first frame body 100 relies on a stable working environment to ensure accuracy and stability, while the vibration device in the second frame body 200 can maximize its vibration performance under the protection of isolation design, improve material flowability, and reduce material blockage, thereby ensuring efficient operation of the entire system.

[0054] In some embodiments, a sieve part 230 is arranged on the second frame body 200 between the first discharge port 121 and the conveying groove 210 for screening the material. Specifically, the sieve part 230 has a sieve cavity 231 and a sieve screen 233 arranged in the sieve cavity 231; the sieve cavity 231 has a second discharge port 232, and the material is discharged through the second discharge port 232 after being screened by the sieve screen 233. The sieve part 230 screens the material into particles of a certain size through the sieve screen 233, ensuring that the material can meet the required particle size requirement during conveying. Specifically, the sieve part 230 can screen out large particles or impurities in the material, filter out materials that do not meet the standard, and ensure the normal operation of subsequent processes or devices.

[0055] In some embodiments, referring to Figure 5 , the conveying groove 210 is provided with a first limiting plate 240 and a second limiting plate 250 along the extension direction, and a conveying channel 260 is formed between the first limiting plate 240 and the second limiting plate 250. Through the two limiting plates, the conveying path of the material can be controlled to ensure the stability and smoothness of the material during conveying, and to avoid uneven flow caused by material scattering or external factors. At least one slide rod 270 passes through the first limiting plate 240 and the second limiting plate 250, and both ends of the slide rod 270 are fixedly connected with the conveying groove 210; the distance between the first limiting plate 240 and the second limiting plate 250 is adjusted along the axial direction of the slide rod 270, so as to adjust the width of the conveying channel 260. It can be understood that the process of adjusting the width of the conveying channel 260 is very convenient, and can quickly respond to changes in different material sizes or production requirements, and has strong flexibility to meet the requirements of different materials and production processes. For example, the width of the conveying channel 260 is designed to be adjustable in the range of 150-350 mm, which can be adjusted by adjusting the width between the first limiting plate 240 and the second limiting plate 250 to adapt to different width of dry electrode products.

[0056] In some embodiments, referring to Figure 5 , 8-11, the conveying channel 260 is provided with a flow guide plate 280, the two ends of the flow guide plate 280 are fixedly connected with the first limiting plate 240 and the second limiting plate 250 respectively; one side of the flow guide plate 280 facing the conveying channel 260 is provided with a first flow guide column 281 and a second flow guide column 282; the first flow guide column 281 is located on both sides of the flow guide plate 280, and the second flow guide column 282 has a plurality of second flow guide columns and is uniformly distributed in the middle of the flow guide plate 280 along the conveying direction of the material; the first flow guide column 281 is used for guiding the material to be conveyed in the direction of the second flow guide column 282, and the second flow guide column 282 is used for uniformly laying the material in the conveying channel 260. The function of the flow guide plate 280 is to guide the flow direction of the material, so that the material can be more uniformly distributed in the conveying process, thereby avoiding the deviation, accumulation or uneven flow of the material in the conveying process. Among them, the first flow guide column 281 is located on both sides of the flow guide plate 280, mainly used for guiding the material to be conveyed in the direction of the second flow guide column 282, playing a role in guiding the flow direction of the material, ensuring the material to flow in the correct direction, avoiding the material deviating from the conveying path. In addition, the second flow guide column 282 is arranged in the middle of the flow guide plate 280 and is uniformly distributed along the conveying direction of the material, and there are usually multiple second flow guide columns. Its role is to uniformly lay the material in the conveying channel 260, avoid the material from being too concentrated or accumulated, ensure the uniform flow of the material in the entire channel, and avoid the conveying problem caused by uneven distribution of the material. Through such uniform distribution, the flowability of the material can be optimized, which can ensure that the powder material is uniformly laid in the set slot width range when conveying, and the consistency of the film thickness of the dry electrode is ensured.

[0057] Further, with reference to Figures 10-11 , the second flow guide column 282 is in a "V" shape structure, the opening of the second flow guide column 282 faces the material conveying direction, and the number increases and the size decreases along the direction. It can be understood that the special shape of the "V" shape structure can gradually guide the material when passing through the flow guide column, ensuring the balance and uniformity of the material flow. Specifically, the opening of the flow guide column faces the flow direction of the material, which helps to guide the material into the flow guide column and distribute along the center line of the conveying channel 260, ensuring that the material is not easy to deviate from the center and avoiding uneven accumulation. Along the conveying direction of the material, the number of the second flow guide column 282 gradually increases. Through the gradual increase of the number, the material can be better dispersed, ensuring the uniform flow of the material in the entire conveying channel 260. With the increase of the number, the control of the flow guide column on the material flow becomes more and more fine, effectively guiding the material to the predetermined position. The size of the second flow guide column 282 gradually decreases in the conveying direction. With the increase of the number of flow guide columns, a more fine guiding force is exerted on the material through the gradually smaller size, avoiding the excessive aggregation of the material in the channel, and helping the uniform spreading of the material.

[0058] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the described embodiment, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application, and these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
