Description

Technical Field

[0001] This invention relates to the field of material feeding technology, specifically to a material crushing mechanism, a feeding device, a feeding system, and an automated feeding method. Background Technology

[0002] The document "Quality Management of Cathode Materials for Lithium-ion Batteries" points out that the performance of lithium-ion batteries is closely related to the quality of the cathode materials. When metallic impurities such as iron (Fe), copper (Cu), chromium (Cr), nickel (Ni), zinc (Zn), and silver (Ag) are present in the cathode materials, these metals will first oxidize at the cathode and then be reduced at the anode. When the metal elemental deposits accumulate to a certain level at the anode, the hard edges of the deposited metal can pierce the separator, causing the battery to self-discharge. In addition, excessive moisture content and poor batch consistency can also seriously harm battery performance. Therefore, avoiding these failures from a quality management perspective is an effective solution to further prevent quality problems and improve the quality of lithium-ion batteries.

[0003] For the reasons mentioned above, the production process of lithium battery materials has clear regulations regarding the type, weight, mixing process, and mixing time limit of each raw material or substitute. Even a small error in a production step can lead to the scrapping of the entire batch of products. Therefore, for industrial production, material input is the most crucial step, playing a decisive role in the production outcome.

[0004] Existing feeding stations typically rely on manual feeding. Operators place packaging bags on the station's support frame, push the bags into the grid using the frame, make an opening in the bag, and shake it to empty the contents. This manual feeding method is not only harmful to operators but also requires manual opening of the bag's side wall. Excessive human intervention can lead to feeding errors, and the manual shaking process can cause the material to be exposed to air for extended periods, resulting in excessive moisture or impurities, ultimately causing the aforementioned failures. Summary of the Invention

[0005] To address the aforementioned technical deficiencies, this invention provides a breaking mechanism, a feeding device, a feeding system, and an automated feeding method. The breaking mechanism can maintain a dynamic seal at the opening after the packaging bag is punctured, reducing the probability of contamination by moisture or metal impurities during the feeding process. This solves the problem of the significant harm to human health caused by manual feeding and reduces the occurrence of failure modes such as the introduction of metal foreign objects, excessive moisture, and poor batch consistency.

Detailed Implementation

[0057] To make the technical solutions and advantages of the embodiments of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0058] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0059] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0060] In this invention, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0061] In the material feeding process of industrial production, the inventors discovered that existing feeding stations typically rely on manual feeding. Operators place packaging bags on a support frame at the feeding station, push the bags into the grid using the frame, make an opening in the bag, and shake it to empty the material inside. Manual feeding poses significant health risks, and the need to make an opening in the side of the bag increases the risk of raw materials or substitutes being left inside, impacting production results.

[0062] To address the aforementioned problems, this invention provides a material breaking mechanism, comprising: a workbench with a feeding channel, the feeding end of which has a flange extending away from the workbench; a piercing portion, the distal end of which is connected to the feeding end, and the outer diameter of the distal end being smaller than the inner diameter of the flange, the proximal end of which forms a piercing tip, and a hollow portion formed on the piercing portion at least near the piercing tip, the hollow portion communicating with the feeding channel; and an iron removal device located at the discharge end of the feeding channel for removing impurities from lithium battery materials. This invention opens the material bag to be fed through the piercing tip of the crushing mechanism. The material inside the material bag slides down along the shape of the piercing part and enters the feeding channel through the hollow part of the piercing tip. This solves the problems of the great harm to human body caused by manual feeding and the impact of incomplete material feeding on production results. In addition, the flange set in this invention can seal the piercing part and the material bag to be fed due to resistance, preventing the material from spilling onto the worktable. The iron removal device of the crushing mechanism is used to remove metal impurities generated during material transportation, preventing metal impurities from contaminating the lithium battery material.

[0063] Example 1

[0065] Figure 2 This is a schematic diagram of the material crushing mechanism 2 provided in Embodiment 1 of the present invention, as shown below. Figure 2 As shown, the material breaking mechanism 2 includes: a workbench 22, on which a feeding channel 21 is provided, the feeding end of the feeding channel 21 having a flange 213 extending away from the workbench 22; a piercing part, the distal end of which is connected to the feeding end, and the outer diameter of the distal end is smaller than the inner diameter of the flange 213, the proximal end of which forms a piercing tip 211, and the piercing part having a hollowed-out portion at least near the piercing tip, the hollowed-out portion communicating with the feeding channel 21; and an iron removal device 26, located at the discharge end of the feeding channel 21, used to remove impurities from the lithium battery material.

[0066] The workbench 22 is used to place the material package to be fed. The piercing tip 211 breaks the bottom of the material package placed on the surface of the workbench 22, allowing the material inside the material package to enter the feeding channel 21 through the hollowed-out portion of the piercing tip 211. The flange 213 can seal the piercing portion and the material package due to resistance, preventing material from spilling onto the workbench. The piercing tip 211 is made of polyethylene material to prevent the generation of metal impurities that may mix into the material and affect the production results.

[0067] In this embodiment, the piercing portion includes a piercing section at the proximal end and a guide section at the distal end. The piercing section is conical, the diameter of the guide section is not less than the diameter of the cone, and the height of the guide section is greater than or equal to one-third of the height of the piercing section. Specifically, the piercing tip 211 is conical, which facilitates piercing. The guide section increases resistance to slow down the opening of the rupture and guides the material package to be fed down.

[0068] In this embodiment, the thickness of the flange 213 is 3-5 mm;

[0069] And / or, the flange 213 is made of an anti-slip material;

[0070] And / or, the surface of the flange 213 is covered with an anti-slip layer; the anti-slip layer is rubber;

[0071] And / or, the inner wall of the feeding channel 21 and the surface of the puncture portion are coated with a PTFE coating or an ECTFE coating. The PTFE coating or ECTFE coating can further prevent the generation of metal impurities and ensure material quality.

[0072] In this embodiment, the workbench 22 is also provided with a striking part, which is located around the puncture part and includes a vertical rod and a swing arm that is swayably mounted on the vertical rod. The free end of the swing arm is provided with a flexible striking unit.

[0073] The slapping parts are multiple, and each slapping part is arranged at equal intervals around the periphery of the puncture part.

[0074] The tapping unit includes a push rod cylinder 23, which taps the material package to be fed, facilitating rapid material discharge. All raw materials in the feeding channel 21 undergo iron removal by the iron removal device 26 before proceeding to the next process.

[0075] like Figure 2 As shown, in this embodiment, the crushing mechanism 2 further includes a data display panel 24 and a control panel 25. The data display panel 24 is used to display the working status of the crushing mechanism 2, and the control panel 25 is used to control the working status of the crushing mechanism 2.

[0076] The feeding mechanism 1 is suspended above the crushing mechanism 2 and is used to grab the material package to be fed and transport the material package to be fed to the puncture part of the crushing mechanism 2 by translation or telescopic movement.

[0078] Specifically, the horizontal moving unit 11 is connected to the vertical moving unit 12, and the vertical moving unit 12 is connected to the robotic arm 13. The robotic arm 13 is used to grasp the material package to be fed from the feeding station. The horizontal moving unit 11 is used to drive the robotic arm 13 to move horizontally, and the vertical moving unit 12 is used to drive the robotic arm 13 to move vertically. Under the operation of the horizontal moving unit 11 and the vertical moving unit 12, the robotic arm 13 delivers the material package to be fed onto the workbench 22. Specifically, the feeding mechanism 1 also includes a mounting base, which is connected to the horizontal moving unit 11 and used to support the horizontal moving unit 11. The horizontal moving unit 11 is connected to the vertical moving unit 12 and used to drive the vertical moving unit 12 to move. The vertical moving unit 12 is connected to the robotic arm 13 and used to drive the robotic arm 13 to move both horizontally and vertically.

[0079] Figure 3 This is a schematic diagram of the structure of the lateral moving unit provided in Embodiment 1 of the present invention, as shown below. Figure 3 As shown, further, the lateral movement unit 11 includes a lateral slide rail suspended above the crushing mechanism 2, a lateral slider is mounted on the lateral slide rail, and the lateral slider is electrically connected to a lateral drive unit. The lateral slide rail is the second slide rail 115 in 3, and the lateral slider is... Figure 3 The second slider 114 in the middle, as Figure 3 As shown, the lateral movement unit 11 includes a second drive unit, a second slider 114, and a second slide rail 115. The second slider 114 is mounted on the second slide rail 115 and is connected to both the second drive unit and the vertical movement unit 12. The second drive unit drives the second slider 114 to move laterally on the second slide rail 115, causing the vertical movement unit 12 to move laterally along with the second slider 114. Specifically, the lateral movement unit 11 also includes a connecting plate 116. The second drive unit includes a servo motor 111, a gear 112, and a rack 113. The drive end of the servo motor 111 is connected to the gear 112, and the rack 113 meshes with the gear 112. The servo motor 111 is mounted on the connecting plate 116, which is fixedly connected to the second slider 114. The servo motor 111 drives the gear 112 to move on the rack 113, causing the connecting plate 116 to move the second slider 114 on the second slide rail 115, thus achieving lateral movement. The connecting plate 116 is also connected to the vertical moving unit 12, and is used to drive the vertical moving unit 12 to move laterally. The second slide rail 115 and the rack 113 are mounted on the mounting base.

[0080] Figure 4 This is a schematic diagram of the structure of the vertical moving unit provided in Embodiment 1 of the present invention, as shown below. Figure 4As shown, furthermore, the vertical moving unit 12 includes a telescopic component connected to the free end of the horizontal slider, and the telescopic component is electrically connected to the vertical driving unit; specifically, as... Figure 4 As shown, the vertical moving unit 12 includes a third driving unit and a telescopic assembly. The third driving unit is used to drive the telescopic assembly to extend and retract. The telescopic assembly is connected to the robotic arm 13 and is used to drive the robotic arm 13 to move vertically. Specifically, the vertical moving unit 12 also includes a connecting rod 124, which is used to connect to the connecting plate 116 of the horizontal moving unit 11. The telescopic assembly includes a second push rod motor 121, a linear bearing guide rail 122, and a guide rod 123. The second push rod motor 121 extends and retracts, thereby driving the guide rod 123 to extend and retract along the linear bearing guide rail 122, realizing the movement of the vertical moving unit 12.

[0081] Figure 5 This is a schematic diagram of the structure of the robotic arm provided in Embodiment 1 of the present invention, as shown below. Figure 5As shown, further, the robotic arm 13 is mounted on the free end of the telescopic assembly, and is used to rise or fall by the extension and retraction of the telescopic assembly, and / or to translate by the movement of the lateral slider, thereby transporting the material package to be fed to the puncturing part of the crushing mechanism 2. Specifically, the robotic arm 13 includes a first drive unit, a force transmission arm 132, a first slider 133, a first slide rail 134, and a gripping arm 135. The drive end of the first drive unit is connected to the first end of the force transmission arm 132, and the second end of the force transmission arm 132 is linked to the first slider 133. The first drive unit drives the first section of the force transmission arm 132 to move up and down, causing the second end of the force transmission arm 132 to move horizontally. The first slider 133 slides on the first slide rail 134 under the drive of the force transmission arm 132. The first slider 133 is also connected to the gripping arm 135, and the first slider 133 is used to drive the gripping arm 135 to move. Specifically, the first drive unit operates, with the drive end causing the first end of the force transmission arm 132 to move vertically, causing the second segment of the force transmission arm 132 to move horizontally, thereby causing the first slider 133 to move, which in turn causes the first slider 133 to move the gripping arm 135. The gripping arm 135 is a two-finger parallel gripper 136, which includes a first vertical plate and a first horizontal plate. One end of the first vertical plate is connected to the force transmission arm 132, and the other end of the first vertical plate is connected to one end of the first horizontal plate.

[0082] Iron removal device

[0083] Example 2

[0084] Figure 6 This is a structural block diagram of an automated material feeding system based on the Internet of Things provided in Embodiment 2 of the present invention. Figure 6 As shown, this embodiment provides an automated feeding system based on the Internet of Things, including: a control module and a feeding device as described in Embodiment 1;

[0085] The control module is used to receive a first control command, generate a feeding command according to the first control command, send the feeding command to the feeding mechanism 1, and generate a breaking command and send the breaking command to the breaking mechanism 2.

[0086] The feeding mechanism 1 is used to feed the material package to be fed according to the received feeding instruction;

[0087] The material breaking mechanism 2 is used to break the material package to be fed according to the received material breaking instruction.

[0088] In this embodiment, the system further includes a warehouse management subsystem, an automated guided vehicle (AGV), and a manufacturing execution subsystem. The warehouse management subsystem acquires production demand information and sends it to the manufacturing execution subsystem. The manufacturing execution subsystem generates transportation instructions based on the received production demand information and sends these instructions to the AGV. The AGV acquires and transports material packages according to the received transportation instructions, and sends a transportation completion instruction to the manufacturing execution subsystem upon completion of transporting the material packages. The manufacturing execution subsystem also issues a first control instruction to the control module based on the received transportation completion instruction.

[0089] Specifically, process technicians issue tasks in the warehouse management subsystem. The warehouse management subsystem retrieves production demand information from the database and sends it to the manufacturing execution subsystem. Upon receiving the production demand information, the manufacturing execution subsystem generates a transportation instruction and sends it to the automated guided vehicle (AGV). After receiving the signal, the AAV retrieves the material package to be fed at the designated location. After retrieving the material package, the AAV transports the material to the lithium battery material feeding station and transmits a transportation completion instruction to the upper-level manufacturing execution subsystem. Upon receiving the transportation completion instruction, the manufacturing execution subsystem transmits the transportation completion instruction and the material package information to the warehouse management subsystem and the control module. The manufacturing execution subsystem also stores the transportation instruction, transportation completion instruction, and control instructions. After receiving the transportation completion signal, the control module sends a signal to the first drive unit of the control robot 13, causing it to control the robot 13 to grab the material package to be fed, place the material package stably on the feeding platform, and control the breaking mechanism 2 to break the bag and feed the material package.

[0090] In this embodiment, the system further includes a database server, a remote mobile terminal, and a control terminal; the remote mobile terminal is used to send a second control command to the control module; the control module is also used to generate feeding commands and breaking commands based on the second control command; the database server is connected to the control module through an intranet penetration tool, and is used to receive and store the command data sent by the control module, the command data including the transportation command and first control command of the production and manufacturing subsystem, the transportation completion command of the automated guided vehicle, the second control command of the remote mobile terminal, the feeding command, and the breaking command; the database server is also used to store production demand information; the control terminal is used to manage the command data stored in the database server.

[0091] Specifically, the intranet penetration tool includes an intranet router, a PeanutShell box, a PeanutShell server, and a database server. The intranet router connects to the PLC control cabinet. The PLC control cabinet uses the PLC's MODBUS communication protocol to connect to the PeanutShell box via the intranet router. The PeanutShell box is configured to connect to an external Wi-Fi network and penetrate to the external PeanutShell server. The PeanutShell server connects to the database server, and the database is hosted on the database server. In this design, the PLC is the intranet hardware device, with its Ethernet port IP address being 192.168.0.20, subnet mask 255.255.255.0, and default gateway 0.0.0.0. The IP address of the PeanutShell box is 192.168.0.100. The intranet uses an intranet router or intranet switch to establish MODBUS communication between the PeanutShell box and the PLC. The PeanutShell box establishes communication with the external PeanutShell cloud server, binding PeanutShell to a personal account. After this, PeanutShell needs to be connected to the internet; this system connects to a mobile phone's personal hotspot. PeanutShell's cloud server is deployed on a personal computer, which also hosts a MySQL database. This server boasts high availability and fault tolerance, automatically recovering from database server failures. This ensures high availability and data consistency during downtime. Furthermore, it offers excellent query performance, handling a large volume of queries and responding quickly. This allows the database server to handle high-concurrency query requests and achieve high throughput, facilitating information access. Its IP address is 172.0.0.1. By entering the internal database's IP address in PeanutShell's internal network address field, data interaction with the internal database can occur. This process involves PLC data to the internal router, the internal router to PeanutShell, and PeanutShell then using a personal hotspot to penetrate the network to the cloud server, where the server stores the data in the internal database. Similarly, data retrieval from the PLC control cabinet follows the reverse process.

[0092] In this embodiment, as Figure 2 As shown, the material breaking mechanism 2 includes: a workbench 22, on which a feeding channel 21 is provided, the feeding end of the feeding channel 21 having a flange 213 extending away from the workbench 22; a piercing part, the distal end of which is connected to the feeding end, and the outer diameter of the distal end is smaller than the inner diameter of the flange 213, the proximal end of which forms a piercing tip 211, and a hollow part is provided on the piercing part at least near the piercing tip, the hollow part communicating with the feeding channel 21; and an iron removal device 26, provided at the discharge end of the feeding channel 21, for removing impurities from lithium battery materials.

[0107] In this embodiment, the control module is a PLC control cabinet, which is connected to the first drive unit, the second drive unit, the third drive unit, and the tapping unit. The PLC control cabinet is used to issue feeding instructions to the first drive unit, the second drive unit, and the third drive unit. The feeding instructions include grabbing instructions, horizontal movement instructions, vertical movement instructions, and dispensing instructions.

The control module and AAV execute actions according to these commands, effectively eliminating the risk of human error in material feeding. The control terminal manages and monitors the data stored in the database, ensuring reliable traceability of production results. Remote mobile terminals control the control module, eliminating the need for on-site personnel to manage the operation, effectively reducing production pressure, improving product stability and quality, and making related information easier to control, making it suitable for high-volume production.

[0110] Example 3

[0111] Figure 7 This is a flowchart of an automated material feeding method based on the Internet of Things (IoT) provided in Embodiment 3 of the present invention, as shown below. Figure 7 As shown, this embodiment provides an automated feeding method based on the Internet of Things (IoT). The method is applied to an IoT-based automated feeding system and includes:

[0112] S1. Receive the first control command through the control module, and generate feeding command and crushing command according to the first control command;

[0113] S2. Receive feeding instructions through feeding mechanism 1, and feed the material package to be fed according to the received feeding instructions;

[0114] S3. Receive the crushing instruction through the crushing mechanism 2, and crush the material package to be fed according to the received feeding instruction.

[0115] In this embodiment, the method further includes:

[0116] The production demand information is obtained through the warehouse subsystem and then sent to the production execution subsystem.

[0117] The manufacturing execution subsystem generates transportation instructions based on the received production demand information and sends the transportation instructions to the automated guided vehicle.

[0118] The automated guided vehicle acquires and transports the material package to be fed according to the received transport instructions, and sends a transport completion instruction to the production execution subsystem when the transport of the material package to be fed is completed.

[0119] The manufacturing execution subsystem issues the first control command to the control module based on the received transportation completion instruction.

[0120] The IoT-based automated feeding method provided in this embodiment is applied to an IoT-based automated feeding system, which includes a control module and a feeding device.

[0121] The control module is used to receive a first control command, generate a feeding command according to the first control command, send the feeding command to the feeding mechanism 1, and generate a breaking command and send the breaking command to the breaking mechanism 2.

[0122] The feeding mechanism 1 is used to feed the material package to be fed according to the received feeding instruction;

[0123] The material breaking mechanism 2 is used to break the material package to be fed according to the received material breaking instruction.

[0124] In this embodiment, the system further includes a warehouse management subsystem, an automated guided vehicle (AGV), and a manufacturing execution subsystem. The warehouse management subsystem acquires production demand information and sends it to the manufacturing execution subsystem. The manufacturing execution subsystem generates transportation instructions based on the received production demand information and sends these instructions to the AGV. The AGV acquires and transports material packages according to the received transportation instructions, and sends a transportation completion instruction to the manufacturing execution subsystem upon completion of transporting the material packages. The manufacturing execution subsystem also issues a first control instruction to the control module based on the received transportation completion instruction.

[0125] Specifically, process technicians issue tasks in the warehouse management subsystem. The warehouse management subsystem retrieves production demand information from the database and sends it to the manufacturing execution subsystem. Upon receiving the production demand information, the manufacturing execution subsystem generates a transportation instruction and sends it to the automated guided vehicle (AGV). After receiving the signal, the AAV retrieves the material package to be fed at the designated location. After retrieving the material package, the AAV transports the material to the lithium battery material feeding station and transmits a transportation completion instruction to the upper-level manufacturing execution subsystem. Upon receiving the transportation completion instruction, the manufacturing execution subsystem transmits the transportation completion instruction and the material package information to the warehouse management subsystem and the control module. The manufacturing execution subsystem also stores the transportation instruction, transportation completion instruction, and control instructions. After receiving the transportation completion signal, the control module sends a signal to the first drive unit of the control robot 13, causing it to control the robot 13 to grab the material package to be fed, place the material package stably on the feeding platform, and control the breaking mechanism 2 to break the bag and feed the material package.

[0126] In this embodiment, the system further includes a database server, a remote mobile terminal, and a control terminal; the remote mobile terminal is used to send a second control command to the control module; the control module is also used to generate feeding commands and breaking commands based on the second control command; the database server is connected to the control module through an intranet penetration tool, and is used to receive and store the command data sent by the control module, the command data including the transportation command and first control command of the production and manufacturing subsystem, the transportation completion command of the automated guided vehicle, the second control command of the remote mobile terminal, the feeding command, and the breaking command; the database server is also used to store production demand information; the control terminal is used to manage the command data stored in the database server.

[0127] Specifically, the intranet penetration tool includes an intranet router, a PeanutShell box, a PeanutShell server, and a database server. The intranet router connects to the PLC control cabinet. The PLC control cabinet uses the PLC's MODBUS communication protocol to connect to the PeanutShell box via the intranet router. The PeanutShell box is configured to connect to an external Wi-Fi network and penetrate to the external PeanutShell server. The PeanutShell server connects to the database server, and the database is hosted on the database server. In this design, the PLC is the intranet hardware device, with its Ethernet port IP address being 192.168.0.20, subnet mask 255.255.255.0, and default gateway 0.0.0.0. The IP address of the PeanutShell box is 192.168.0.100. The intranet uses an intranet router or intranet switch to establish MODBUS communication between the PeanutShell box and the PLC. The PeanutShell box establishes communication with the external PeanutShell cloud server, binding PeanutShell to a personal account. After this, PeanutShell needs to be connected to the internet; this system connects to a mobile phone's personal hotspot. PeanutShell's cloud server is deployed on a personal computer, which also hosts a MySQL database. This server boasts high availability and fault tolerance, automatically recovering from database server failures. This ensures high availability and data consistency during downtime. Furthermore, it offers excellent query performance, handling a large volume of queries and responding quickly. This allows the database server to handle high-concurrency query requests and achieve high throughput, facilitating information access. Its IP address is 172.0.0.1. By entering the internal database's IP address in PeanutShell's internal network address field, data interaction with the internal database can occur. This process involves PLC data to the internal router, the internal router to PeanutShell, and PeanutShell then using a personal hotspot to penetrate the network to the cloud server, where the server stores the data in the internal database. Similarly, data retrieval from the PLC control cabinet follows the reverse process.
