Description

Technical Field

[0001] This invention belongs to the field of profile circulation and management technology, specifically relating to a profile circulation monitoring and conveying system and method based on a cloud platform. Background Technology

[0002] Currently, aluminum alloy profile manufacturers typically use a logistics slip system for profile circulation. This means that after a frame of profiles is produced and assembled, a logistics slip is manually created as a record, and the circulation and tracking of profiles are done on a per-frame basis. Because the profiles need to undergo multiple transfers and stages, this existing method is prone to oversights or errors due to human factors, has low automation, low efficiency, and lacks flexibility.

[0003] In actual production, especially for large-scale manufacturing enterprises, the output of profiles is extremely large. It is common to find during inventory that one or two profiles are missing from a certain material box. Once this happens, it is necessary to process a replacement order separately and use a material box with only one or two of the missing profiles to circulate on the production line. This is very troublesome, as it consumes manpower, material resources, and time.

[0004] Therefore, a new solution is needed to manage the flow of profiles in a more refined and automated manner. However, due to the different shapes of various profiles, it is difficult to design a universally applicable automatic flow monitoring solution. As a result, no company has developed such a system on the market yet. Summary of the Invention

[0019] The testing platform is also equipped with a code recognition sensor switch, which is located below the profile code recognition unit.

[0020] Preferably, the material transfer mechanism includes a profile pushing linear module, on which a pushing block is provided; the pushing block has a baffle for pushing the profile, and the baffle is higher than the upper surface of the detection platform.

[0021] Preferably, the detection platform is also equipped with a reverse conveyor belt, the conveying direction of which is opposite to that of the material transfer mechanism.

[0022] Preferably, the position identifier includes multiple sensors arranged along the conveying direction of the material transfer mechanism.

[0023] Preferably, the framing mechanism includes two swing arm bases located on both sides of the line connecting the detection platform and the material frame, with swing arms rotatably connected to the swing arm bases and swing motors connected to the swing arms; a basket is suspended above the swing arms.

[0024] Furthermore, cantilever arms are provided above the two swing arms and extend opposite to each other. Electric telescopic rods are provided on the cantilever arms along their length. The ends of the electric telescopic rods are connected to pulleys. A hoist is provided on the swing arms. The hoist is connected to a rope. The rope passes through the pulleys and is connected to the suspended basket.

[0025] The suspended platform has a frame structure that runs through both sides. The bottom of the suspended platform is a base plate, and the rope is connected to the center of the base plate. The two ends of the profile are placed on the base plates of the two suspended platforms respectively.

[0027] The profile shape recognition unit is connected to the detection platform through a horizontally arranged profile recognition linear module.

[0028] This invention also provides a cloud-based profile circulation monitoring and conveying method, implemented using the cloud-based profile circulation monitoring and conveying system of this invention, which includes the following steps:

[0029] In step S1, the profile is transported to the testing platform by external equipment. The feeding mechanism drives the profile to continue moving to the middle of the testing platform, and the profile is detached from the external equipment.

[0030] Step S2: After the profile is moved into place, the profile shape recognition unit recognizes the cross-sectional shape and size of the profile and feeds back the obtained shape and size information to the main control computer. The main control computer processes the information and interacts with the database of the cloud platform to obtain the profile's model and standard size information.

[0031] Step S3: The main control computer encodes according to the preset encoding rules and feeds the encoding information back to the laser etching machine. The laser etching machine then performs the encoding etching action on the surface of the profile.

[0032] Step S4: After etching is completed, the material transfer mechanism continues to push the profile to the area below the profile coding and identification unit. The profile coding and identification unit identifies the code and feeds back the obtained coding information to the main control computer. Then, the material transfer mechanism continues to push the profile to the transfer platform. The position identifier identifies the position and quantity of the profiles placed on the transfer platform.

[0033] Step S5: Repeat steps S1 to S4. The subsequent profiles are placed side by side in sequence after being moved to the transfer platform until the recognition result of the position identifier shows that the number of placed profiles has reached the upper limit or the set value.

[0034] Step S6: The framing mechanism moves multiple profiles placed on the transfer platform to the material frame;

[0035] Step S7: After the framing is completed, the frame number recognition unit recognizes the frame number plate of the frame and feeds back the obtained frame number information to the main control computer. The main control computer integrates the frame number information and the coding information of all profiles in the frame and uploads it to the cloud platform for storage.

[0036] In one specific embodiment, the position identifier includes a plurality of photoelectric sensors arranged along the conveying direction of the material transfer mechanism, and the spacing between the plurality of photoelectric sensors is the same;

[0037] In steps S4 and S5, the process by which the position identifier identifies the position and quantity of the profiles includes:

[0038] The first profile conveyed to the transfer platform stops moving after it covers the photoelectric sensor closest to the downstream end of the position identifier. The main control computer calculates the remaining position distance of the transfer platform based on the coverage of the photoelectric sensor. If the remaining position distance is greater than the width of the profile, steps S1 to S4 are repeated. Subsequent profiles stop moving after they cover the photoelectric sensor closest to the downstream end of the position identifier that was not previously covered. The main control computer then judges the remaining position distance again. If the remaining position distance is less than the width of the profile, it means that the number of profiles placed has reached the upper limit.

[0039] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0040] 1. This solution identifies and etches a number onto each profile before framing, and records and uploads the information to the cloud platform. This enables precise monitoring during the profile circulation process. It can monitor not only the condition of the frame but also the condition of each individual profile. As a result, any missing profiles can be detected in time, allowing for retrieval or replacement, saving manpower and time. It also avoids the situation where omissions are only discovered during inventory before delivery, while improving the efficiency of inventory and reducing the workload of manual labor.

[0041] 2. This solution uses a series of specially configured sensors, such as position identifiers, combined with a main control computer and cloud platform, to achieve automated intelligent control. It is applicable to various profiles and has strong versatility, especially suitable for profiles with high hardness and rigidity.

[0042] 3. This solution encodes the surface of each profile using specific coding rules, creating a unique identification code for each profile. In addition to facilitating monitoring during the circulation process, it can also serve as an anti-counterfeiting mark in subsequent use after leaving the factory. Based on the profile type and number, relevant information can be found in the data stored on the cloud platform, thereby assisting in resolving disputes. Attached Figure Description

[0077] A. Profiles. Detailed Implementation

[0078] The main objective of this invention is to solve the problem of refined management of profiles. To this end, a cloud-based profile flow monitoring and conveying system and method are designed. The system structure mainly includes a detection platform 1, a laser etching machine 4, a profile coding and identification unit 5, a profile shape identification unit 6, a transfer platform 5, a position identifier 3, a framing mechanism, a material frame 7, a material frame number identification unit 9, a main control computer, and a cloud platform. The method mainly includes feeding, identifying profile shape, etching codes, recording profile codes, processing multiple profiles, framing, and recording material frame numbers. This solution assigns a material code to each profile and then uses the material frame as the logistics flow unit for each process, achieving more mechanized, automated, intelligent, and refined profile flow and management. Each profile can be specifically monitored, avoiding oversights caused by manual operation and ensuring timely detection. Furthermore, it is applicable to various profiles and has strong versatility.

[0079] Please see Figure 1 An embodiment of the present invention discloses a cloud-based profile flow monitoring and conveying system, including a detection platform 1 for placing profile A for identification, encoding, recording, and other operations for monitoring and management. The detection platform 1 is located, for example, behind the transmission frame of the profile sawing mechanism. After the profile is formed and sawn to the required length, it is conveyed onto the detection platform 1. The detection platform 1 is equipped with a feeding mechanism and a transferring mechanism for conveying profile A.

[0080] Specifically, please also refer to Figure 2 The testing platform 1 is, for example, a stand structure. The upper surface of the testing platform 1 is a placement surface for the profile A, and the lower part is a support. The feeding mechanism includes an electric conveyor roller 25 located at the upstream end of the testing platform 1, thereby driving the profile A placed on it towards the downstream end of the feeding mechanism. Figure 2The profile A moves (below) the feeder. A feed sensor switch 26 is installed at the upstream end of the feed path of the feeding mechanism. When the profile A moves to cover or move out of the feed sensor switch 26, the feed sensor switch 26 generates a corresponding signal. Preferably, the feed sensor switch 26 is position-adjustable, such that the distance between it and the profile shape recognition unit 6 is slightly greater than the length of the profile A, so that the profile A moves out of the position above the feed sensor switch 26, which is suitable for the profile shape recognition unit 6 to recognize the profile A.

[0081] Preferably, a profile baffle 27 is also movably installed at the downstream end of the conveying route of the feeding mechanism. For example, the profile baffle 27 is connected to the detection platform 1 through a telescopic cylinder. The profile baffle 27 can block and position the profile A in front of the profile shape recognition unit 6, and then can move up / down / left / right without obstructing the recognition of the profile shape recognition unit 6.

[0082] The material transfer mechanism includes, for example, a profile pushing linear module 23, on which a pushing block 24 is provided. A linear module slot is provided on the placement surface of the detection platform 1, and both the profile pushing linear module 23 and the pushing block 24 are located within the linear module slot. The pushing block 24 has a baffle for pushing the profile A. The baffle is higher than the upper surface of the detection platform 1, thus forming a structure with a protruding, movable baffle on the horizontal placement surface. The baffle pushes the profile A forward from the rear. Preferably, there are at least two sets of profile pushing linear modules 23, for example, three sets, arranged side-by-side at intervals to ensure that the profile A moves smoothly and is directly aligned with the profile shape recognition unit 6 (i.e., the length direction of the profile A is...). Figure 2 (The vertical direction should be maintained, and the object should not be tilted).

[0083] Preferably, the detection platform 1 is also provided with a reverse conveyor belt 29. The conveying direction of the reverse conveyor belt 29 is opposite to the conveying direction of the material transfer mechanism. It can drive the profile A to move in the opposite direction, so that the profile abuts against the baffle (or other baffle structure for positioning) of the pusher block 24 on the upstream side, thereby adjusting and positioning it so as to scan the profile shape recognition unit 6.

[0084] Above the inspection platform 1, for example via columns or cantilever arms, are a laser etching machine 4 and a profile coding identification unit 5. The laser etching machine 4 is used to etch codes on the surface of profile A. The profile coding identification unit 5 is located downstream of the laser etching machine 4 along the conveying direction of the transfer mechanism and is used to identify and record the codes on the surface of profile A. Specifically, for example, the inspection platform 1 is connected to a first lifting linear module 19 and a second lifting linear module 20. The laser etching machine 4 is connected to the first lifting linear module 19, and the profile coding identification unit 5 is connected to the second lifting linear module 20. Thus, the laser etching machine 4 and the profile coding identification unit 5 can be raised and lowered under control, adjusted to a suitable height according to the profile size for etching or identification work, and can also be raised during the conveying of profile A to prevent scratches. More preferably, both the first lifting linear module 19 and the second lifting linear module 20 are connected to the inspection platform 1 via a horizontally arranged profile coding linear module 21, which is mounted above the inspection platform 1 via a column.

[0085] A profile shape recognition unit 6 is installed on the side of the inspection platform 1, below the laser etching machine 4, for recognizing the shape of the profile. The profile shape recognition unit 6 is preferably connected to the inspection platform 1 via a horizontally arranged profile recognition linear module 22. The laser etching machine 4, the profile coding recognition unit 5, and the profile shape recognition unit 6 can all be adjusted manually or automatically to face the profile A, thus facilitating the completion of the corresponding tasks.

[0086] The testing platform 1 is also equipped with a code recognition sensor switch 28, which is located below the profile code recognition unit 5. When profile A moves above the code recognition sensor switch 28, it stops moving. The code recognition unit 5 identifies and records the profile code, and then continues to transport it for framing. This ensures that each profile is recorded before framing, and that profiles can be removed or added according to actual conditions (e.g., if staff find unqualified profiles) before code recognition and recording. The transport of profiles is not limited by code generation or etching sequence, making it flexible in use.

[0087] Downstream of the detection platform 1 along the conveying direction of the transfer mechanism ( Figure 2 On the right side of the middle section, a transfer platform 2 is provided continuously or independently. The range of the material transfer mechanism extends to the downstream end of the transfer platform 2. The transfer platform 2 is used to stack the profiles to be loaded into the frame for transfer that have undergone coding, recording and other procedures.

[0088] A position identifier 3 is installed on the transfer platform 2 to identify the position and quantity of profile A. Preferably, the position identifier 3 includes multiple photoelectric sensors arranged along the conveying direction of the material transfer mechanism. The length of the arrangement is slightly shorter than the width of the transfer platform 2, and the spacing between the multiple photoelectric sensors is the same, for example, 1 cm, thus forming multiple signal sources. When profile A moves onto the transfer platform 2 and partially covers the signal sources, the main control computer can obtain the position of profile A and the remaining stacking space on the transfer platform 2.

[0089] A framing mechanism is provided on the downstream side of the transfer platform 2. A material frame 7 is placed on the downstream side of the framing mechanism (for example, placed in a specific material frame placement area). A material frame number plate 8 is provided on one side of the material frame 7. A material frame number identification unit 9 is also included, which faces the material frame number plate 8 to identify and record the number of the material frame.

[0090] Please see Figure 3 The framing mechanism includes two swing arm bases 10 located on either side of the line connecting the detection platform 1 and the material frame 7. Swing arms 11 are rotatably connected to the swing arm bases 10, and swing arms 11 are connected to swing motors 12. For example, the swing arms 11 have a pivot shaft, and the swing arm bases 10 have pivot holes, forming a pivot connection with the pivot shaft. The pivot shaft is connected to the output end of the swing motor. A basket 13 for supporting the profile is suspended above the swing arms 11. In one specific embodiment, cantilever arms 14 extend oppositely above the two swing arms 11. Electric telescopic rods 15 are oppositely arranged along the length direction on the cantilever arms 14. A pulley 16 is connected to the end of the electric telescopic rod 15. A hoist 17 is provided on the swing arms 11, and a rope 18 is wound and connected to the hoist 17. The rope 18 passes through the pulley 16 (and may also pass through several fixed pulleys provided on the swing arms 11) and is connected to the basket 13. The suspended platform 13 has a frame structure that runs through both sides. The bottom of the suspended platform 13 is a base plate, and the rope 18 is connected to the center of the top of the base plate of the suspended platform 13. The two ends of the profile A are placed on the base plates of the two suspended platforms 13 respectively.

[0091] The working process and principle of the above-mentioned framing mechanism are as follows: After a certain number of profiles are stacked on the transfer platform 2, the swing arm 11 swings the basket 13 to the upper sides of the transfer platform 2. At this time, the electric telescopic rod 15 is in the retracted state, and the distance between the two baskets 13 is greater than that of profile A and is located outside the two ends of profile A. The hoist 17 releases the rope 18 outward, the bottom plate of the basket 13 descends to below profile A, then the electric telescopic rod 15 extends, the distance between the two baskets 13 shortens, and they are placed around a row of profiles. The hoist 17 rewinds the rope 18, and the basket 13 rises to lift the profile. Please refer to [link / reference needed] for details during this process. Figure 2Both ends of profile A are suspended outside the transfer platform 2, and the movement of the basket 13 is not obstructed by the transfer platform 2. The swing arm 11 swings the basket 13 to the material frame 7, and releases the profile into the material frame 7 in a similar reverse process.

[0092] The main control computer is connected to the aforementioned electrical devices in this system to receive signals or perform control. The main control computer is, for example, a computer system including servo control, data processing, storage, and uploading functions, and includes a display screen showing material frame and profile information, logistics actions, and logistics stages for easy viewing. The cloud platform, or cloud-based data platform, is connected to the main control computer via a wireless network for information exchange, such as receiving, storing, processing, and sending data and signals. Preferably, it also includes a client, such as a mobile application, capable of sending requests to the cloud platform and receiving message pushes, enabling users to query the flow and transportation process of profiles anytime, anywhere based on their profile codes.

[0093] It should be noted that each linear module in this solution includes a slide table, slide rail, and servo motor, all controlled and driven by the main control computer. Each recognition unit is, for example, a 3D scanner capable of visual recognition, obtaining the cross-sectional shape, dimensions, or identifying characters of the profile. All of the above components can be implemented using existing technologies, and the computer system and programs can also be designed and implemented based on existing technologies; therefore, they will not be elaborated upon further.

[0094] Please see Figure 4 Based on the system described above, the present invention also provides a cloud platform-based profile circulation monitoring and transportation method, which, taking a preferred embodiment as an example, includes the following steps.

[0095] Step S1, loading. After being processed in the previous process, such as sawing, at the upstream end of the inspection platform 1, profile A is transported to the electric conveyor roller 25 of the inspection platform 1 by external equipment such as a conveyor frame. Profile A covers and triggers the feeding induction switch 26, and the electric conveyor roller 25 starts accordingly, and the profile baffle plate 27 moves into place; the electric conveyor roller 25 drives profile A to continue moving to the middle of the inspection platform 1, and profile A is removed from the external equipment.

[0096] According to the specific settings, when profile A passes the feed sensor switch 26 or is blocked by the profile baffle plate 27, it is considered that profile A has moved into place, the electric conveyor roller 25 stops, the material transfer mechanism (including the reverse conveyor belt 29) starts, and stops after 10 seconds. The profile baffle plate 27 retracts, so that profile A is positioned and aligned, and the side of profile A faces the profile shape recognition unit 6.

[0097] Optionally, the profile shape recognition unit 6 then begins to recognize the position of profile A and feeds the position information back to the main control computer. After calculation, the main control computer controls the profile shape recognition unit 6 and the laser etching machine 4 to move to a position directly opposite the center line of profile A.

[0098] Step S2: Identify the profile shape. The profile shape recognition unit 6 identifies the cross-sectional shape and dimensions of profile A, and feeds back the obtained shape and dimension information to the main control computer. After processing the information, the main control computer interacts with the database of the cloud platform to obtain information such as the model and standard dimensions of profile A.

[0099] Step S3, Etching Code. The main control computer encodes the code according to the preset coding rules and feeds the coded information back to the laser etching machine 4. The laser etching machine 4 performs the etching action of coding on the surface of the profile A. The code consists of letters and numbers, and the information on which it is generated includes at least one of the following: profile type, production batch, process content, machine number, and machine start time. Each generated code is unique.

[0100] Step S4: Record the profile code. After etching is completed, the transfer mechanism continues to push profile A forward. After profile A covers the trigger code recognition induction switch 28, it stops moving. The profile code recognition unit 5 begins to recognize the code and feeds back the obtained code information to the main control computer. Then, the transfer mechanism continues to push profile A to the transfer platform 2. The position recognizer 3 recognizes the position and quantity of the profiles placed on the transfer platform 2.

[0101] Step S5: Process multiple profiles. Repeat steps S1 to S4. Subsequent profiles are placed side by side in sequence after being moved to the transfer platform 2 until the recognition result of the position identifier 3 shows that the number of placed profiles has reached the upper limit or the set value.

[0102] Step S6, framing. The framing mechanism transports multiple profiles placed on the transfer platform 2 to the material frame 7.

[0103] Step S7: Record the frame number. After the frames are assembled, the frame number recognition unit 9 identifies the frame number plate 8 of the frame 7 and sends the obtained frame number information back to the main control computer. The main control computer integrates the frame number information, the coding information of all profiles in the frame 7, and may also include information such as the current time, production batch, and process type, and uploads it to the cloud platform for storage. Then, the frame 7 is transferred to the next process by subsequent external equipment such as a crane. This system operates in a repetitive manner.

[0104] In subsequent processes, the frame and each profile are identified and recorded using a similar structure and method; this eliminates the need for the laser etching machine 4, the profile shape recognition unit 6, and related structures and steps. In this way, the quantity and code of the profiles in each frame 7 are recorded in the cloud platform, and the automated loading process prevents any omissions. This is equivalent to automatic inventory monitoring before each frame, allowing for timely detection and rapid resolution of any problems.

[0105] Furthermore, in steps S4 and S5, the process by which the position identifier 3 in the preferred embodiment identifies the position and quantity of profile A includes:

[0106] The first profile A conveyed to the transfer platform 2 stops moving after covering the photoelectric sensor closest to the downstream end of the position identifier 3. The transfer mechanism returns to its initial position to wait for the next profile A to be transported. Simultaneously, the main control computer calculates the remaining position distance of the transfer platform 2 based on the coverage status of the photoelectric sensor. If the remaining position distance is greater than the width of profile A, steps S1 to S4 are repeated. Subsequent profile A stops moving after covering the previously uncovered photoelectric sensor closest to the downstream end of the position identifier 3. The main control computer again determines the remaining position distance. If the remaining position distance is less than the width of profile A, it indicates that the maximum number of profiles A placed has been reached. That is, on the transfer platform 2, profile A from... Figure 2 The profiles are stacked sequentially from right to left, and the photoelectric sensor of the position identifier 3 is covered. When the area of ​​the uncovered photoelectric sensor is insufficient to accommodate one profile A, it indicates that the transfer platform 2 is full of profiles A. It should be noted that the width of the basket 13 matches the length of the position identifier 3 to ensure that the basket 13 can cover the stacked row of profiles A.

[0107] In summary, this solution identifies and etches a number onto each profile before framing, recording and uploading the information to a cloud platform. This enables precise monitoring during profile circulation, monitoring not only the frame but also each individual profile. Any missing profiles can be detected promptly, allowing for retrieval or replacement, saving manpower and time, improving inventory efficiency, and reducing manual workload. Furthermore, this solution utilizes a series of specifically designed sensors, including position identifiers, combined with a main control computer and cloud platform, to achieve automated intelligent control. It is applicable to profiles of various widths, offering strong versatility, and is particularly suitable for profiles with high hardness and rigidity. Furthermore, this solution encodes the surface of each profile using specific coding rules, creating a unique identification code for each profile. Besides facilitating monitoring during the distribution process, it also serves as an anti-counterfeiting measure after the profile leaves the factory. For example, if a problem arises with a particular profile during use, relevant information can be retrieved from the cloud platform's stored data based on the profile type and serial number to determine if it is a product from this factory and at which stage of distribution the problem occurred. This helps resolve disputes externally and facilitates quality traceability and process improvement internally. It is highly practical for aluminum profile manufacturers, especially large enterprises.

The feeding mechanism drives the profile to continue moving to the middle of the testing platform (1), and the profile is removed from the external equipment. Step S2: After the profile is moved into place, the profile shape recognition unit (6) recognizes the cross-sectional shape and size of the profile and feeds back the obtained shape and size information to the main control computer. The main control computer processes the information and interacts with the database of the cloud platform to obtain the profile model and standard size information. Step S3: The main control computer encodes according to the preset encoding rules and feeds back the encoding information to the laser etching machine (4). The laser etching machine (4) performs the encoding etching action on the surface of the profile. Step S4: After etching is completed, the material transfer mechanism continues to push the profile to the bottom of the profile coding identification unit (5). The profile coding identification unit (5) identifies the code and feeds back the obtained coding information to the main control computer. Then the material transfer mechanism continues to push the profile to the transfer platform (2). The position identifier (3) identifies the position and quantity of the profile placed on the transfer platform (2). Step S5, repeat steps S1 to S4, the subsequent profiles are placed side by side after being moved to the transfer platform (2) until the recognition result of the position identifier (3) shows that the number of placed profiles has reached the upper limit or the set value. Step S6, the framing mechanism transports the multiple profiles placed on the transfer platform (2) to the material frame (7). Step S7: After the frame is assembled, the frame number identification unit (9) identifies the frame number plate (8) of the frame (7) and feeds back the obtained frame number information to the main control computer. The main control computer integrates the frame number information and the coding information of all profiles in the frame (7) and uploads it to the cloud platform for storage.

When the remaining position distance is greater than the width of the profile, steps S1 to S4 are repeated. The subsequent profile stops moving after it covers the photoelectric sensor that is closest to the downstream end of the position identifier (3) and was not previously covered. The main control computer then judges the remaining position distance again. When the remaining position distance is less than the width of the profile, it means that the number of profiles placed has reached the upper limit.
