Description

Technical Field

[0001] This application relates to the field of battery production technology, and in particular to a particulate matter-based weighing and feeding device and a cylindrical battery production line. Background Technology

[0002] In the current production process of cylindrical batteries, conductive material, specifically positive electrode particles, needs to be directly added inside the battery's steel casing to increase conductivity. Therefore, the accuracy of the amount of positive electrode particles added is crucial. Existing methods involve first pouring the particles into the steel casing and then weighing them. If the amount is insufficient, a second filling is performed. However, excessive filling results in defective products, and the amount of positive electrode particles added to each battery cannot be uniform, affecting battery consistency. Utility Model Content

[0003] To address one of the aforementioned technical problems, this application provides a particulate matter weighing and feeding device and a cylindrical battery production line, including a feeding component and a feeding rack connected to the discharge end of the feeding component. A weighing component is disposed at the discharge end of the feeding rack. A graduated roller is rotatably disposed inside the feeding rack. The outer circumferential surface of the graduated roller has a plurality of graduated grooves that communicate with the discharge end of the feeding component. The graduated roller rotates to transfer the graduated grooves from the discharge end of the feeding component to the discharge end of the feeding rack. Particulate matter then falls from the discharge end of the feeding rack onto the weighing component, is weighed, and after passing the weighing, is poured into the battery casing, thereby ensuring a uniform amount of particulate matter in each battery and improving battery consistency.

[0004] Preferably, the feeding assembly includes a feeding funnel and a vibrator disposed on one side of the feeding funnel. The discharge end of the feeding funnel is connected to the feed inlet of the feeding rack via a pipe. After the granular material is poured into the feeding funnel, it falls through the pipe into the graduated groove of the graduated roller in the feeding rack. Then, as the graduated roller rotates, the granular material in the graduated groove is discharged onto the weighing assembly.

[0005] Preferably, one side of the feeding rack has a first placement cavity for placing the graduated roller, and the other side of the feeding rack has a second placement cavity. The second placement cavity is equipped with a replenishing graduated roller. A rotary drive is provided on the feeding rack to drive the graduated roller and the replenishing graduated roller to rotate. The outer circumferential surface of the replenishing graduated roller has a replenishing graduated groove that communicates with the discharge end of the feeding assembly. The rotary drive drives the replenishing graduated roller to rotate, so that the replenishing graduated groove is transferred from the discharge end of the feeding assembly to the discharge end of the feeding rack. For example, the rotary drive can be a motor, which drives the graduated roller and the replenishing graduated roller to rotate, so that the particulate material can be fed into the weighing assembly through the graduated groove.

[0006] Preferably, the top and bottom of the feeding rack are provided with a first inlet and a first outlet connecting to the first placement cavity, and a second inlet and a second outlet connecting to the second placement cavity. The size of the second inlet is smaller than that of the first inlet, the size of the second outlet is smaller than that of the first outlet, and the size of the replenishing scale groove is smaller than that of the scale groove. Therefore, the replenishing scale roller can be driven to rotate by a rotary drive component, causing the particles in the replenishing scale groove to be replenished to the weighing component. Since the size of the replenishing scale groove is smaller than that of the scale groove, when the weighing component detects insufficient weight of the particles, replenishing can be performed through the replenishing scale roller, thereby fine-tuning the weight of the particles until it meets the requirements.

[0007] Preferably, the weighing assembly includes a weighing platform, a weighing sensor disposed within the weighing platform, a weighing cup disposed on the weighing platform, and a transfer assembly for transferring the weighing cup disposed on one side of the weighing platform. The particle material is then fed into the weighing cup by the rotation of a graduated roller and a feeding graduated roller. The weighing cup is then weighed by the weighing sensor on the weighing platform. After passing the weighing test, the particle material in the weighing cup is poured into the battery casing by the transfer assembly.

[0008] Preferably, the transfer assembly includes a first linear module, a second linear module disposed at the drive end of the first linear module, and a flipping module disposed at the second linear module. The drive end of the flipping module is provided with a clamping plate for holding the weighing cup. The first and second linear modules can be driven by a drive mechanism consisting of a motor and a lead screw, thereby achieving horizontal and vertical driving movement. The flipping module can be a rotary motor.

[0009] Preferably, an NG recycling bin is also provided on one side of the weighing platform. When the weighing is excessive, the particulate matter in the weighing cup is poured into the NG recycling bin for recycling through a transfer component, reducing the defect rate and avoiding waste.

[0010] Preferably, the assembly further includes a filling component, which includes a support frame for supporting the steel shell, a funnel slidably disposed on the support frame, and a lifting driver 53 for driving the funnel to move up and down. The lifting driver 53 then drives the funnel 52 to move closer to or further away from the battery steel shell on the support frame 51. The transfer component 40 pours the particles from the weighing cup 33 into the funnel 52, and the particles then fall into the steel shell through the funnel 52, thus completing the filling process.

[0011] Preferably, the filling assembly further includes a movable base and an extrusion drive, wherein the support frame is slidably disposed on the movable base, and the extrusion drive is used to drive the movable base to move on the support frame. The movable base can be installed on a steel shell transfer conveyor line, thereby driving the steel shell transfer and conveying. The support frame is slidably disposed on the movable base through a slide rail and slider structure, and the extrusion drive (56) is used to drive the movable base to move on the support frame.

[0012] Preferably, a cylindrical battery production line includes the aforementioned particulate-based weighing and feeding device. By weighing the particulate matter using the weighing and feeding device, the amount of particulate matter poured into each battery is ensured to be uniform, thereby improving battery consistency and production quality.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: This application connects a feeding rack to the discharge end of the feeding component, and a weighing component is provided at the discharge end of the feeding rack. A scale roller is rotatably arranged inside the feeding rack. The outer circumferential surface of the scale roller is provided with several scale grooves. When the scale grooves are connected to the discharge end of the feeding component, the granular material fills the scale grooves. Then the scale roller rotates to transfer the scale grooves from the discharge end of the feeding component to the discharge end of the feeding rack. Then the granular material falls from the discharge end of the feeding rack onto the weighing component, is weighed by the weighing component, and is poured into the battery casing after passing the weighing. This ensures that the amount of granular material poured into each battery is uniform, thereby improving the consistency of the batteries. Attached Figure Description

[0030] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0031] To address the aforementioned technical problems, this embodiment provides a particulate matter weighing and feeding device, such as... Figure 1 As shown, the device includes a feeding assembly 10 and a feeding rack 21 connected to the discharge end of the feeding assembly 10. A weighing assembly 30 is provided at the discharge end of the feeding rack 21. A scale roller 22 is rotatably installed inside the feeding rack 21. Several scale grooves 221 are formed on the outer circumferential surface of the scale roller 22. When the scale grooves 221 are connected to the discharge end of the feeding assembly 10, the granular material fills the scale grooves 221. Then, the scale roller 22 rotates to transfer the scale grooves 221 from the discharge end of the feeding assembly 10 to the discharge end of the feeding rack 21. The granular material then falls from the discharge end of the feeding rack 21 onto the weighing assembly 30 and is weighed by the weighing assembly 30. After the weighing is qualified, the material is poured into the battery casing, thereby ensuring that the amount of granular material poured into each battery is uniform, thus improving the consistency of the batteries.

[0032] Specifically, such as Figure 2 As shown, the feeding assembly 10 includes a feeding funnel 11, a vibrator 12 disposed on one side of the feeding funnel 11, and a frame 13. The feeding funnel 11 is mounted on the frame 13. The discharge end of the feeding funnel 11 is connected to the feed inlet of the feeding rack 21 through a pipe. After the granular material is poured into the feeding funnel 11, it falls through the pipe into the graduated groove 221 of the graduated roller 22 inside the feeding rack 21. After the graduated roller 22 rotates, the granular material in the graduated groove 221 is discharged onto the weighing assembly 30. During this process, the vibrator 12 vibrates the feeding funnel 11 to ensure that all the granules in the graduated groove 221 are discharged onto the weighing assembly 30.

[0033] Furthermore, such as Figure 3-6As shown, one side of the feeding rack 21 has a first placement cavity 211 for placing the graduated roller 22, and the other side of the feeding rack 21 has a second placement cavity 214. The second placement cavity 214 is provided with a replenishing graduated roller 24. A rotary drive component 23 is provided on the feeding rack 21 to drive the graduated roller 22 and the replenishing graduated roller 24 to rotate. For example, the rotary drive component 23 can be a motor, which drives the graduated roller 22 and the replenishing graduated roller 24 to rotate, so that the particulate material can be fed into the weighing assembly 30 through the graduated groove 221.

[0034] Among them, such as Figure 7 As shown, a feeding scale groove 241 is formed on the circumferential surface of the feeding scale roller 24, which is connected to the discharge end of the feeding assembly 10. The feeding scale roller 24 is driven to rotate by the rotary drive component 23, so that the feeding scale groove 241 is transferred from the discharge end of the feeding assembly 10 to the discharge end of the feeding rack 21. A first air hole 242 is formed at the bottom of the feeding scale groove 241, and a second air hole 243 is formed on the side of the feeding scale roller 24. The second air hole 243 is connected to the air blowing component. When the feeding scale groove 241 is transferred to the discharge end of the feeding rack 21, air is blown through the first air hole 242 at the bottom of the feeding scale groove 241, so that the particles in the feeding scale groove 241 fall into the weighing assembly 30.

[0035] In the above scheme, the top and bottom of the feeding rack 21 are provided with a first inlet 212 and a first outlet 213 connecting the first placement cavity 211, and a second inlet 215 and a second outlet 216 connecting the second placement cavity 214. The size of the second inlet 215 is smaller than that of the first inlet 212, and the size of the second outlet 216 is smaller than that of the first outlet 213. Specifically, this size is the opening radius, that is, the opening radius of the second inlet 215 is smaller than that of the first inlet 212, and the opening radius of the second outlet 216 is smaller than that of the first outlet 213. Then, the feeding scale roller 24 can be driven to rotate by the rotary drive component 23, so that the particles in the feeding scale groove 241 are fed into the weighing component 30. The size of the feeding scale groove 241 is smaller than that of the scale groove 221. Specifically, this size refers to the volume, meaning that the volume of the feeding scale groove 241 is smaller than that of the scale groove 221. Therefore, when the weighing component 30 finds that the weight of the particles is insufficient, the feeding scale roller 24 can be used to replenish the particles, thereby fine-tuning the weight of the particles until it is qualified.

[0036] Furthermore, such as Figure 8-9As shown, the weighing assembly 30 includes a weighing platform 31, a weighing sensor 32 disposed within the weighing platform 31, a weighing cup 33 disposed on the weighing platform 31, and a transfer assembly 40 for transferring the weighing cup 33 disposed on one side of the weighing platform 31. The particle material is fed into the weighing cup 33 by the rotation of the graduated roller 22 and the feeding graduated roller 24. The weighing cup 33 is then weighed by the weighing sensor 32 on the weighing platform 31. After passing the weighing test, the particle material in the weighing cup 33 is poured into the battery casing by the transfer assembly 40.

[0037] Furthermore, an NG recycling bin 34 is provided on one side of the weighing platform 31. When the weighing is excessive, the particles in the weighing cup 33 are poured into the NG recycling bin 34 by the transfer component 40 for recycling, thereby reducing the defect rate and avoiding waste.

[0038] Furthermore, the transfer assembly 40 includes a first linear module 41, a second linear module 42 disposed at the drive end of the first linear module 41, and a flipping module 43 disposed at the drive end of the second linear module 42. The drive end of the flipping module 43 is provided with a clamping plate 44 for holding the weighing cup 33. For example, the first linear module 41 and the second linear module 42 can be driven by a drive mechanism composed of a motor and a lead screw, thereby achieving horizontal and vertical drive movement through the first linear module 41 and the second linear module 42. The flipping module 43 can be a rotary motor. For example, a bidirectional cylinder can be provided at the drive end of the flipping module 43. The drive end of the bidirectional cylinder is connected to the clamping plate 44, thereby driving the clamping plate to clamp or release the weighing cup 33 on the weighing platform 31. The weighing cup 33 is moved above the battery casing by the first linear module 41 and the second linear module 42. Then, the flipping module 43 drives the clamping plate 44 and the weighing cup 33 to rotate 180°, thereby pouring the particles in the weighing cup 33 into the battery casing.

[0039] The above scheme also includes a filling component 50, such as... Figure 9-10 As shown, the filling assembly 50 includes a support frame 51 for supporting the steel shell, a funnel 52 slidably disposed on the support frame 51, and a lifting driver 53 for driving the funnel 52 to move up and down on the support frame 51. The lifting driver 53 can be a cylinder, thereby driving the funnel 52 to move closer to or away from the battery steel shell on the support frame 51. The transfer assembly 40 pours the particles in the weighing cup 33 into the funnel 52, and then the particles fall into the steel shell through the funnel 52, thereby completing the filling process.

[0040] Furthermore, the filling assembly 50 also includes a movable base 54 and an extrusion drive 56. The movable base 54 can be installed on a steel shell transfer conveyor line, thereby driving the steel shell transfer and conveying. The support frame 51 is slidably mounted on the movable base 54 through a slide rail and slider structure. The extrusion drive 56 is used to drive the movable base 54 to move on the support frame 51. For example, the extrusion drive 56 can be a cylinder mounted on the movable base 54, thereby driving the support frame 51 to perform horizontal reciprocating motion, thereby ensuring that all the positive electrode particles in the funnel can be discharged into the steel shell. Alternatively, in some other implementations, the movable base 54 is connected to one end of the support frame 51 by a spring 55. In this case, the extrusion drive 56 can be installed on the frame 13 or the feeding rack 21. Then, the drive end of the extrusion drive 56 extends and abuts against the other end of the support frame 51 relative to the spring 55, so that the support frame 51 slides on the movable base 54 and is compressed by the spring 55. After the drive end of the extrusion drive 56 is reset, the support frame 51 is reset under the action of the spring 55.

[0041] On the other hand, this embodiment provides a cylindrical battery production line, including the above-mentioned particulate-based weighing and feeding device. The particulate matter is weighed by the weighing and feeding device to ensure that the amount of particulate matter poured into each battery is uniform, thereby improving the consistency of the batteries and improving the production quality of the batteries.

[0042] In summary, in one or more embodiments of this application, the solution of this application connects a feeding rack to the discharge end of the feeding assembly, and a weighing assembly is provided at the discharge end of the feeding rack. A scale roller is rotatably arranged inside the feeding rack, and a plurality of scale grooves are formed on the outer circumferential surface of the scale roller. When the scale grooves are connected to the discharge end of the feeding assembly, the particulate material fills the scale grooves. Then the scale roller rotates to transfer the scale grooves from the discharge end of the feeding assembly to the discharge end of the feeding rack. Then the particulate material falls from the discharge end of the feeding rack onto the weighing assembly, is weighed by the weighing assembly, and is poured into the battery casing after passing the weighing. This ensures that the amount of particulate material poured into each battery is uniform, thereby improving the consistency of the batteries.

[0043] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
