Description

Technical Field

[0001] This utility model relates to the field of automated production technology of cemented carbide, and specifically to an intelligent production line for cemented carbide. Background Technology

[0002] In the field of cemented carbide production, the production line is the core set of equipment that transforms raw materials into finished products. Its structural rationality and degree of automation directly affect production efficiency, product quality, and production costs. Currently, most conventional cemented carbide production lines on the market adopt a traditional decentralized structural design, with equipment in each production stage relatively independent and lacking unified modular integration. This leads to many problems that urgently need to be addressed in actual production processes. First, there is a high degree of reliance on manual labor. In the existing production line, the raw material handling process requires manual transfer of raw material barrels from the raw material workshop to the extruder. The extrusion feeding process requires manual assistance in positioning the raw material barrels and completing the feeding operation. The product receiving process requires manual docking of the cutting machine output boats and transferring them to the subsequent workstations. The above manual operations not only lead to low production efficiency, but are also prone to affecting the product processing accuracy due to human operation errors (such as raw material barrel positioning deviations and boat collisions during transport). At the same time, it increases labor costs and safety risks in production.

[0003] Secondly, the equipment suffers from poor coordination and insufficient structural flexibility. Traditional cemented carbide production lines often employ fixed structural designs for their various functional components (such as conveying equipment, drying equipment, and weighing equipment). The lack of standardized connection interfaces between these components makes it impossible to quickly adjust equipment combinations or replace functional units according to production needs. For example, when producing cemented carbide products of different specifications, the drying equipment in the drying stage requires manual adjustment of temperature, humidity, and ventilation parameters. This cannot be achieved through adaptive adjustments to the production line structure, which not only prolongs the production cycle but also wastes energy, making it difficult to adapt to the demands of small-batch, multi-variety cemented carbide production.

[0004] Third, the structural support for production data traceability is lacking. In existing production lines, the recording of production data (such as raw material batch numbers, vessel numbers, product weighing data, etc.) mostly relies on paper documents or independent manual entry systems. The production line itself does not integrate structural units for data collection and correlation (such as hardware integration structures for barcode reading mechanisms and data transmission interfaces), resulting in the inability to correlate production data with the hardware operations of each link in the production line in real time, forming "information silos." When it is necessary to trace the production process of a certain batch of products, a large number of paper records or data from multiple independent systems need to be manually retrieved, and the traceability response time can be as long as several hours. Moreover, data loss or mismatch problems are prone to occur, which is not conducive to the rapid location and resolution of quality problems.

[0005] In summary, existing cemented carbide production lines suffer from defects in structural design, such as high reliance on manual labor, poor coordination, insufficient flexibility, and lack of data traceability support. There is an urgent need for a modular production line structure to solve these problems and improve the automation level and operational efficiency of cemented carbide production.

[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0023] Example The core of the cemented carbide intelligent production line in this embodiment lies in the precise connection and coordinated operation of five modular functional units to achieve full-process automation from raw material transportation to finished product outbound sampling inspection. Its specific implementation structure and working process are as follows, and each module is connected to achieve data interaction with external manufacturing execution system (MES) and warehouse management system (WMS) through hardware interfaces to ensure a dual closed loop of structure and data.

[0024] Specifically, see Figure 1-6 The cemented carbide intelligent production line includes a material barrel conveying and feeding module 1, a boat and dish feeding and conveying module 2, a loading machine module 3, a drying storage module 4, and an outbound weighing and sampling inspection module 5. The drying storage module 4 is equipped with an automatic guided vehicle passage mechanism for material cart transfer, the material bucket conveying and feeding module 1 is used to convey raw materials to the cemented carbide processing equipment, and the boat and dish feeding and conveying module 2 is used to transfer the boats and dishes after cemented carbide processing. The material barrel conveying and feeding module 1, the boat and dish feeding and conveying module 2, and the loading machine module 3 are connected sequentially along the cemented carbide production process; The drying storage module 4 is connected downstream of the loading module 3 of the feeding machine, and the outbound weighing and sampling inspection module 5 is connected downstream of the drying storage module 4.

[0025] In this embodiment, the production line is arranged sequentially along the cemented carbide production process: material barrel conveying and feeding module 1 → boat and dish feeding and conveying module 2 → loading machine module 3 → drying storage module 4 → outbound weighing and sampling inspection module 5; wherein, the ground outside the drying storage module 4 is paved with an automated guided vehicle (AGV) docking track adapted to the wheels of the AGV. One end of the track is connected to the ground rail machine 36 of the loading machine module 3, and the other end extends to the return guide rail of the outbound weighing and sampling inspection module 5, forming a transfer channel for material carts (with guide wheels at the bottom, adapted to the track); the material barrel conveying and feeding module 1 is connected to an external extrusion machine (cemented carbide raw material processing equipment), and the boat and dish feeding and conveying module 2 is connected to an external cutting machine (cemented carbide cutting equipment after forming). The hardware interfaces of each module are connected to the MES system deployed in the workshop through shielded wires to realize the issuance of production instructions and the real-time uploading of data.

[0026] Specifically, the barrel conveying and feeding module 1 is connected to the feed end of the extruder in the cemented carbide production process. The barrel conveying and feeding module 1 includes a roller conveyor line 11 for conveying raw material barrels, a first code reading component set in the middle section of the roller conveyor line 11, and an automatic feeding mechanism 12 adapted to the feed end of the extruder. The first code reading component is used to fix and identify the QR code of the raw material barrel. The automatic feeding mechanism 12 corresponds to the feed port of the extruder. The end of the roller conveyor line 11 is provided with a turning mechanism for the return of empty barrels.

[0027] Specifically, the material barrel conveying and feeding module 1 is used to complete the automatic conveying and feeding of raw material barrels from the raw material workshop to the extruder. Its specific structure includes: roller conveyor line 11, first code reading component, automatic feeding mechanism 12, and steering mechanism.

[0028] Its working process is as follows: Manually or by machine, the raw material barrels filled with cemented carbide raw materials (with a QR code label containing the batch number and raw material type affixed to the barrel) are placed at the starting end of the roller conveyor line 11, and the roller conveyor line 11 transports the raw material barrels toward the extruder. When the raw material barrel reaches below the first barcode reader, the first barcode reader scans the QR code on the barrel and uploads the QR code information to the MES system through the hardware interface; the MES system sends a "target loading position signal" to the roller conveyor line 11 according to the preset "raw material batch-extruder correspondence rule"; After receiving the signal, the roller conveyor line 11 continues to operate, transporting the raw material barrel to the designated feeding position next to the corresponding extruder, and transporting the raw material to the feed end of the extruder; After feeding is completed (the extruder sends a "feeding complete signal" through the sensor), the automatic feeding mechanism 12 resets, and the roller conveyor 11 transports the empty raw material barrel to the turning mechanism at the end; the turning mechanism guides the empty barrel to the return roller line (connected to the raw material workshop) to complete the empty barrel recycling.

[0029] Specifically, the beginning of the roller conveyor line is also equipped with an elevator 6 and a corner mechanism 7.

[0030] Specifically, the boat-and-dish feeding and conveying module 2 is connected to the discharge end of the cutting machine in the cemented carbide production process. The boat-and-dish feeding and conveying module 2 includes an upper plate machine 21, a cutting table 22, a lower plate machine 23, and a boat-and-dish production line 24. The upper platen machine 21 and the lower platen machine 23 are respectively located on the left and right sides of the cutting table 22; The upper plate machine 21, the cutting table 22, and the lower plate machine 23 all correspond to the boat-shaped production line 24; The tail end of the boat-and-dish assembly line 24 is connected to the loading module 3 of the feeding machine, and the tail end of the boat-and-dish assembly line 24 is equipped with a boat-and-dish code reader.

[0031] Specifically, the boat and dish feeding and conveying module 2 is used to receive the boats and dishes containing hard alloy molded parts output by the cutting machine, and to complete the orderly conveying and information association of the boats and dishes. Its specific structure includes: upper plate machine 21, cutting table 22 (which is engaged with the cutting machine outlet to ensure precise docking of the boats and dishes), lower plate machine 23, boat and dish production line 24, second boat and dish lifting machine 25, and boat and dish code reading component (which is the same model as the first code reading component and is fixed above the tail end of the boat and dish production line 24).

[0032] Its working process is as follows: Preliminary preparation: Empty boats are neatly placed into the loading machine 21 by manual labor or machine. After the loading machine 21 detects the boats through photoelectric sensors, it sends a "waiting for material" signal to the cutting machine. Boat conveying and loading: After receiving the waiting signal, the cutting machine sends a "boat pick-up signal". The upper tray machine 21 pushes a single empty boat to the cutting table 22, and the cutting table 22 conveys the empty boat into the cutting machine. When the cutting machine completes the cutting of the cemented carbide forming part and fills the boat, it sends a "full material signal" to the middle tray machine. The lower tray machine 23 pushes the full boat to the boat production line 24. Information association and unloading: When the full-loaded boat is conveyed to the end of the boat assembly line 24, the boat barcode reader scans the boat number QR code and uploads the association information of "boat number - cutting machine number - cutting time" to the MES system through the hardware interface; then, the second boat lift 25 receives the full-loaded boat and then connects with the boat reversing conveyor line 31 of the loading module 3 to complete the automatic unloading.

[0033] Specifically, the loading module 3 of the loading machine includes a boat reversing conveyor line 31, a code reading and weighing mechanism 32, a docking line 33, a boat telescopic line 34, a first boat elevator 35, and a ground rail machine 36. The boat-and-dish reversing conveyor line 31 connects to the boat-and-dish feeding and conveying module 2; The boat-and-dish reversing conveyor line 31, the code reading and weighing mechanism 32, the docking line body 33, and the boat-and-dish telescopic line body 34 are connected in sequence. The first boat lift 35 is installed on the ground rail machine 36; The first boat lifting machine 35 corresponds to the boat telescopic line 34.

[0034] Specifically, the loading module 3 of the loading machine is used to load full boats into the material car according to the rules, in preparation for the subsequent drying process. Its specific structure includes: boat reversing conveyor line 31, barcode reading and weighing mechanism 32, docking line 33, boat telescopic line 34, first boat lifting machine 35 (set on ground rail machine 36, the ground rail machine 36 track is connected to the docking track of automatic guide car), and material car.

[0035] Its working process follows the logic of "code reading - weighing - positioning - loading": Boat / Vessel Receiving and Information Verification: The second boat / vessel elevator 25 transports the full boat / vessel to the boat / vessel reversing conveyor line 31. The reversing conveyor line adjusts its direction according to the "boat / vessel-material cart correspondence rules" issued by the MES system, and transports the full boat / vessel to the barcode reading and weighing mechanism 32. The barcode reading and weighing mechanism 32 scans the boat / vessel number a second time (to verify with the number uploaded to the MES system to prevent errors and omissions), and at the same time, the weighing sensor collects the weight of the boat / vessel and uploads the "boat / vessel number-weight" data to the MES system. Loading of boats and containers: After verification, the docking line 33 is started to transport the full boats and containers to the boat and container telescopic line 34; the boat and container telescopic line 34 adjusts the telescopic length according to the current empty space of the material car (the MES system provides real-time feedback on the loading progress of the material car) to push the full boats and containers to the corresponding layer of the material car; the first boat and container elevator 35 on the ground rail machine 36 pushes the material car to the docking track of the automatic guided vehicle and sends a "waiting for transfer signal" to the AGV scheduling system; Empty vehicle replenishment: After receiving the signal, the AGV travels along the automatic guide vehicle docking track to the side of the material vehicle, and drags the full material vehicle to the drying warehouse module 4 through the positioning structure; at the same time, the first boat lifting platform 35 retrieves an empty material vehicle from the empty vehicle storage area of ​​the ground rail machine 36 and places it at the loading station to wait for the next round of loading.

[0036] Specifically, the drying storage module 4 includes a closed storage frame, a temperature and humidity control component, and an automated guided vehicle docking track; The enclosed storage frame is divided into multiple independent drying chambers. Each drying chamber is equipped with a support platform that is compatible with the material cart. The temperature and humidity control components include a variable frequency ventilation fan installed on the top of the storage frame and a temperature and humidity sensor mounting base. The docking track of the automatic guided vehicle is fixedly connected to the ground outside the storage frame, and the track width is compatible with the wheels of the material cart.

[0037] Specifically, the drying storage module 4 is used to achieve constant temperature and humidity drying of full material boats to ensure the stable performance of cemented carbide molded parts. Its specific structure includes: a closed storage frame, temperature and humidity control components, automatic guide vehicle docking track (extending to the door of each drying chamber, with a position encoder next to the track for AGV positioning), and support platform (set in each drying chamber, with a limiting groove on the platform that matches the guide wheels of the material cart to prevent the material cart from shifting).

[0038] Its working process combines adaptive temperature and humidity control with AGV scheduling: Material cart entry: The AGV tows a full material cart along the automated guided vehicle docking track to the drying warehouse module 4. The WMS system sends a "target chamber signal" to the AGV according to the "material cart-chamber correspondence rule" (such as material carts of different raw material batches corresponding to different chambers). The AGV positions itself to the door of the target chamber using the position encoder next to the track, pushes the material cart onto the support platform inside the chamber, and then sends a "warehousing completion signal" to the WMS system. Drying parameter control: After receiving the warehousing signal, the WMS system retrieves the "standard drying parameters" for this batch of cemented carbide molded parts from the MES system and sends the parameters to the temperature and humidity control components of the corresponding drying chamber; the temperature and humidity sensor collects the temperature and humidity data in the chamber in real time. If the temperature is high, the variable frequency ventilation fan automatically increases its speed; if the humidity is high, the ventilation fan keeps running at high speed; if both temperature and humidity meet the standards, the ventilation fan runs at low speed to achieve energy saving; Drying completion scheduling: When the drying time is reached, the MES system sends an "outbound signal" to the AGV scheduling system. The AGV travels to the door of the corresponding chamber, drags the material car to the docking track of the automatic guided vehicle, and transports it in the direction of the outbound weighing and sampling inspection module 5.

[0039] Specifically, the outbound weighing and sampling inspection module 5 includes a weighing platform, a boat-shaped gripper, and a second barcode reader. The weighing platform has a groove on its surface that fits the bottom of the boat-shaped gripper. The boat-shaped gripper is mounted on the weighing platform via a horizontally movable slide rail. The second barcode reader is fixed to one side of the weighing platform and its height corresponds to the position of the QR code on the boat-shaped gripper. The output end of the weighing platform is equipped with a return guide rail that connects to the material cart.

[0040] Specifically, the outbound weighing and sampling module 5 is used to perform weight sampling of the dried boats and dishes to ensure that the moisture content of the cemented carbide molded parts meets the standard (weight loss is within the preset range). Its specific structure includes: a weighing platform, a boat and dish gripping frame, a second barcode reader (with the same model as the first barcode reader and fixed on one side of the weighing platform), and a return guide rail (connected to the docking rail of the automatic guided vehicle and used for the transfer of the material car after the sampling is completed).

[0041] Its working process includes a closed loop of "sampling inspection - comparison - judgment - processing": Material cart arrival and sampling preparation: The AGV drags the dried material cart to the return guide rail of the outbound weighing and sampling module 5 and sends a "sampling signal" to the MES system; After receiving the signal, the MES system sends a "sampling instruction" to the boat gripper. The gripper moves along the transverse slide rail to the top of the material cart and uses visual positioning (a camera is installed next to the slide rail) to align with the last boat on the top layer of the material cart. Code reading and weighing: The elastic grippers of the gripping frame clamp the boat and move it into the groove of the weighing platform; the second code reading component scans the boat number, the MES system retrieves the weight data of the boat before it was put into storage (the data uploaded by the code reading and weighing mechanism 32), the weighing platform collects the current weight data and automatically calculates the weight difference; Result processing: If the weight comparison is qualified (the difference is within the allowable range): the boat and dish gripper will put the boat and dish back to the original position of the material cart, the MES system will send a "qualified signal" to the AGV, the AGV will drag the material cart to the full position (finished product temporary storage area), and at the same time the WMS system will unbind the information binding of "material cart-boat and dish-storage location"; If the weight comparison fails: the MES system sends a "return to warehouse" signal to the AGV, the AGV drags the material cart back to the original drying chamber, and the WMS system updates the drying time; after the extended drying time is over, the AGV transports the material cart to the sampling module again and repeats the above sampling process; if the sampling fails multiple times in a row, the MES system sends an "abnormal alarm" to the workshop control room, and manual intervention is required for inspection (such as whether the moisture content of the raw materials exceeds the standard).

[0042] Specifically, the material barrel conveying and loading module 1, the boat and dish feeding and conveying module 2, and the outbound weighing and sampling inspection module 5 are all equipped with hardware interfaces for connecting to external manufacturing execution systems. The hardware interfaces are electrically connected to each module through wires.

[0043] In this embodiment, the hardware interfaces of all modules interact with the MES system, WMS system, and AGV scheduling system via industrial Ethernet: The MES system is responsible for issuing production instructions (such as loading location, boat-material cart correspondence rules, drying parameters), collecting production data (such as raw material batch, boat weight, drying temperature and humidity), and generating traceability reports. The WMS system is responsible for warehouse location management (such as the allocation of drying chambers and the statistics of empty / full carts), information binding and unbinding; The AGV scheduling system is responsible for scheduling AGVs to complete the transfer of material vehicles based on signals from MES and WMS. Through the above collaboration, the entire process of "raw material input → processing → drying → sampling inspection → warehousing" is automated, requiring only 4 staff members (1 person responsible for the 21-piece tray loading machine, 1 person responsible for the initial placement of raw material barrels, and 2 people responsible for system monitoring and anomaly handling). Compared with the traditional production line (requiring 10 people), it reduces human intervention by more than 60%, increases equipment utilization from 70% to 90%, and shortens the quality traceability response time from 2 hours to within 10 seconds, fully meeting the inventor's proposed technical solution of "full-process automation + data closed-loop management".

[0044] Specifically, the overall working principle of the technical solution in this embodiment is as follows: The material bucket conveying and feeding module 1 conveys the full bucket to the barcode reader. The barcode reader identifies the QR code on the top of the bucket and queries the specific feeding position through MES. After conveying to the designated feeding position, it stops running. The automatic feeding mechanism 12 realizes automatic feeding of the bucket. After feeding is completed, the empty bucket is conveyed to the end return via roller conveyor. Manually place the boats into the hopper 21 of the upper tray machine. After the cutting machine gives an idle signal, the equipment automatically feeds a single boat into the cutting machine. When the cutting machine is full, it gives a full signal. The lower boat receiving equipment receives the full boat, reads the code, and rises to transport the product to the next station. The full boat number is given to the MES system and associated with the product information. After the full boat enters the weighing station, the code is read, the weight is measured, and the boat number and weight information are uploaded to the MES system. According to the confirmed boat and dish placement rules, the material feeding information is fed back to the boat and dish loading module. The boat and dish loading module puts the full boat and dish into the corresponding material car. After the material car is loaded to the specified quantity (according to the order or MES confirmation), the AGV scheduling system pulls the full material car to the corresponding storage location. After receiving the signal that the material cart has been loaded, the warehouse system dispatches AGVs to move the full material cart to the drying position. If the loading position requires an empty material cart, an empty material cart is placed at the loading position. The MES provides the specific drying time based on the product information. After the full material cart has met the drying time, the AGV dispatching system dispatches AGVs to transport the warehouse material cart to the weighing and sampling inspection position. When random sampling is required, the WMS dispatches the AGV to retrieve the material cart to the sampling module according to demand. The sampling module takes out the last tray for sampling and weighing, reads the code, and sends the information (weight, boat number) to the MES system for comparison with the weight before warehousing. Then, the boat is put back into the material cart. After the MES system confirms, it sends information to the AGV. If the weight comparison is not acceptable, the AGV moves the material cart to the original drying location and continues drying according to the fixed proportion of the standard drying time provided. After the second drying time is completed, the first sampling process is repeated. If the weight comparison is still not acceptable, the AGV moves to the original location and continues drying according to the fixed proportion of the standard drying time provided by the customer. This cycle continues until the weight comparison is acceptable. After the weight comparison is acceptable, the information is uploaded to the MES, the AGV moves the material cart to the full position, and at the same time, the WMS is unbound from the material cart and the boat information on it.

[0045] It should be noted that the equipment model, size, speed and other parameters in this embodiment are only preferred options. In actual applications, they can be flexibly adjusted according to production capacity requirements and workshop space. As long as the structural connection and working logic of each module conform to the core design of this utility model, they all fall within the protection scope of this utility model.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope.
