Technical Field
[0001] This application relates to the field of automated production technology, and more specifically, to a method for distributing assembly line carriers and an assembly line production system. Background Technology
[0002] In the field of automated production, when multiple production units with the same function are configured adjacently, a production line can be quickly assembled. Production units can be interconnected via carrier transfer mechanisms, and carriers need to be evenly distributed within each production unit to achieve optimal output. However, in actual production, when one production unit experiences an abnormal production alarm, other production units, due to the unreasonable carrier distribution on their assembly lines, cannot continue production, causing the entire automated production line to stop and severely impacting its utilization rate. Therefore, there is an urgent need to design a carrier distribution method to solve this problem. Summary of the Invention
[0003] The technical problem to be solved by this application is to provide a method for distributing assembly line carriers and an assembly line production system, in view of the above-mentioned defects of the prior art.
[0004] The technical solution adopted by this application to solve its technical problem is: On the one hand, this application provides a method for distributing assembly line vehicles, including: The production unit is configured with parallel production lines, which include an outer production line and an inner production line; If a carrier enters the external assembly line, the carrier and its first status information are acquired and recorded. Based on the first status information, the external assembly line is instructed to allow the carrier to exit the production unit or be temporarily stored. The system detects whether a carrier has entered the internal assembly line. If so, it acquires and records the carrier and its second status information, and based on the second status information, it causes the internal assembly line to send the carrier to the production unit for processing or out of the production unit.
[0005] In some embodiments, detecting whether a carrier enters the external assembly line, and if so, acquiring and recording the carrier and its first state information, and, based on the first state information, causing the external assembly line to discharge the carrier out of the production unit or temporarily store it, includes: When the external production line detects that a carrier has entered, it acquires and records the first status information; wherein, the first status information includes the carrier's first raw material information and first molten material information, as well as the production status information of the next production unit; Based on the first raw material information and the first clinker information, as well as the production status information of the next production unit, the external assembly line causes the carrier to flow out of the production unit or be temporarily stored.
[0006] In some embodiments, the step of causing the external assembly line to discharge the carrier out of the production unit or temporarily store it based on the first raw material information, the first clinker information, and the production status information of the next production unit includes: When the first raw material information shows that the material carried by the carrier is raw material, and the production status of the next production unit is normal, the external assembly line will cause the carrier to flow out of the current production unit. When the first raw material information shows that the material carried by the carrier is raw material, and the production status of the next production unit is abnormal, the carrier is temporarily stored. When the first clinker information shows that the material carried by the carrier is clinker, the external production line will cause the carrier to flow out of the current production unit.
[0007] In some embodiments, detecting whether a carrier enters the internal assembly line, and if so, acquiring and recording the carrier and its second state information, and, based on the second state information, causing the internal assembly line to send the carrier to a production unit for processing or out of the production unit, includes: When the internal assembly line detects the entry of a carrier, it acquires and records the second status information; wherein, the second status information includes the carrier's second raw material information and second clinker information; When the second raw material information shows that the material carried by the carrier is raw material, the production unit will process the material. When the second clinker information shows that the material carried by the carrier is clinker, the inner assembly line will cause the carrier to flow out of the production unit.
[0008] In some embodiments, when the second raw material information indicates that the material carried by the carrier is raw material, causing the production unit to process the material includes: After the production unit successfully processes the raw material, it switches the status information of the carrier from raw material to cooked material and transfers the cooked material to the external production line. If the production unit fails to process raw materials, it switches the status information of the carrier from raw materials to defective products and removes the defective products.
[0009] In some embodiments, before detecting whether a vehicle has entered the outer or inner assembly line, the method further includes: The preceding step identifies the identifier of the material carried by the vehicle to determine whether it is raw or cooked material, so as to perform preliminary screening of the raw and cooked materials; If the initial screening determines that there is an incorrect transfer of raw materials and cooked materials, the corresponding carriers will be diverted to the material verification process. If the initial screening determines that there is no incorrect delivery of raw or cooked materials, then the corresponding carrier is allowed to enter the outer or inner production line.
[0010] In some embodiments, after preliminary screening of the raw materials and clinker, and before the corresponding carrier enters the external or internal production line, the method further includes: The appearance and structure of the raw or cooked materials after initial screening are identified by multidimensional characteristic detection, so as to perform secondary screening of the raw and cooked materials; If, after secondary screening, it is determined that there is an incorrect delivery of raw materials and cooked materials, the corresponding carriers are diverted to enter the material verification process. After verification and adjustment, the corresponding carriers are allowed to enter the outer or inner production line. If, after a second screening, it is determined that there is no incorrect delivery of raw or cooked materials, then the corresponding carrier is allowed to enter the outer or inner assembly line.
[0011] On the other hand, this application also provides a production line system that applies the production line carrier allocation method described in any of the above claims, the system comprising: The parallel production line includes an outer production line and an inner production line; wherein, a lifting buffer mechanism is configured at the outlet position of the outer production line; The production unit is equipped with a carrier transfer mechanism at both the inlet and outlet ends.
[0012] In some embodiments, the system further includes: A preliminary identification mechanism is used to identify the identifier of the material carried by the carrier to determine whether it is raw material or cooked material, so as to perform preliminary screening of the raw material and cooked material; A material verification mechanism is used to verify the materials carried by the carrier; A diversion mechanism is used to divert the carrier to the material verification process.
[0013] In some embodiments, the system further includes: A multidimensional characteristic testing organization is used to identify the appearance and structure of the raw materials or clinker after preliminary screening based on multidimensional characteristic testing, so as to perform secondary screening of the raw materials and clinker.
[0014] The beneficial effects of this application are as follows: Unlike existing technologies, the assembly line carrier allocation method of this application sets up parallel assembly lines for production units, including outer and inner assembly lines; it detects whether a carrier enters the outer assembly line; if so, it acquires and records the carrier and its first state information, and based on the first state information, it causes the outer assembly line to discharge the carrier out of the production unit or temporarily store it; it detects whether a carrier enters the inner assembly line; if so, it acquires and records the carrier and its second state information, and based on the second state information, it causes the inner assembly line to send the carrier to the production unit for processing or discharge it out of the production unit; this not only ensures orderly allocation of processing among production units during normal production, but also helps to adjust the flow of raw materials or processed materials by rationally allocating carrier flow when a single production unit experiences production abnormalities. For example, it allows for temporary storage of raw materials and normal inflow and outflow of processed materials into and out of the production unit, thereby effectively avoiding impact on the operation of the entire automated production line, improving the utilization rate of the automated production line, and effectively guaranteeing the efficiency of automated production.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this application. Obviously, the described embodiments are some embodiments of this application, but not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.
[0021] Example 1: This application provides a method for distributing conveyor belts. This method adjusts the flow of raw materials or clinker by rationally distributing the flow of conveyor belts. For example, it allows raw materials to be temporarily stored and clinker to flow normally into and out of the production unit. This effectively solves the problem of the entire automated production line being affected by the production abnormality of a single production unit. It helps to improve the utilization rate of the automated production line and effectively ensures the efficiency of automated production.
[0022] The specific implementation steps of the assembly line vehicle allocation method in this embodiment are as follows: Figure 1 The diagram shows steps S1-S3, as detailed below: S1: Set up parallel production lines for the production unit, including external production lines and internal production lines; During normal production, the external assembly line allocates carriers to production units according to the production rhythm, ensuring that all production units have raw material processing and improving production efficiency. Through the cooperation of the external and internal assembly lines, a reasonable allocation strategy for carriers is achieved, ensuring the smooth operation of production in each production unit.
[0023] S2: Detect whether a carrier has entered the external assembly line. If so, acquire and record the carrier and its first status information, and according to the first status information, make the external assembly line flow the carrier out of the production unit or temporarily store it. Specifically, such as Figure 2 As shown, step S2 includes: S21: When the external production line detects that a carrier has entered, it acquires and records the first status information; wherein, the first status information includes the first raw material information and the first molten material information of the carrier, as well as the production status information of the next production unit; Based on the acquired information on the first raw material and the first clinker of the carrier, as well as the production status information of the next production unit, it is convenient to rationally process the flow of the carrier through the external assembly line and optimize the production process.
[0024] S22: Based on the information of the first raw material and the first clinker, as well as the production status information of the next production unit, the external assembly line causes the carrier to flow out of the production unit or be temporarily stored.
[0025] Specifically, such as Figure 3 As shown, step S22 includes: S221: When the first raw material information shows that the material carried by the carrier is raw material, and the production status of the next production unit is normal, the external assembly line will cause the carrier to flow out of the current production unit. In this process, after a vehicle leaves the current production unit, it enters the next production unit where production is in normal condition, and the next production unit carries out production and processing. The allocation method and operation are relatively simple and intuitive.
[0026] S222: When the first raw material information shows that the material carried by the carrier is raw material, and the production status of the next production unit is abnormal, the carrier is temporarily stored. One method for temporarily storing the carrier is to lift the carrier using a lifting buffer mechanism to pause its feeding into the production line, or to transfer the carrier to a buffer area using a carrier transfer mechanism for temporary storage. Once the production unit is operating normally, the carrier can be directly fed back into the production line without affecting other processes.
[0027] S223: When the first clinker information shows that the material carried by the carrier is clinker, the external production line will cause the carrier to flow out of the current production unit.
[0028] S3: Detect whether a carrier has entered the inner production line. If so, acquire and record the carrier and its second status information, and according to the second status information, send the carrier to the production unit for processing or out of the production unit.
[0029] Specifically, such as Figure 4 As shown, step S3 includes: S31: When the internal assembly line detects the entry of a carrier, it acquires and records the second status information; wherein, the second status information includes the second raw material information and the second clinker information of the carrier; Based on the acquired information on the second raw material and the second clinker of the carrier, the flow direction of the carrier can be rationally processed through the internal assembly line, thereby further optimizing the production process.
[0030] S32: When the second raw material information shows that the material carried by the carrier is raw material, the production unit will process the material. Specifically, such as Figure 5 As shown, step S32 includes: S321: After the production unit successfully processes the raw material, it switches the status information of the carrier from raw material to finished material and transfers the finished material to the external production line. S322: After the production unit fails to process raw materials, the status information of the carrier is switched from raw materials to defective products, and the defective products are removed.
[0031] One method to remove defective products is to set up a separate defective product production line to send the carriers containing defective products to the defective product area. This can effectively prevent defective products from flowing into other normal production processes, thereby improving the control of production quality.
[0032] S33: When the second clinker information shows that the material carried by the carrier is clinker, the inner assembly line will cause the carrier to flow out of the production unit.
[0033] Furthermore, in this embodiment, before detecting whether a vehicle has entered the outer or inner assembly line, the assembly line vehicle allocation method further includes: S4: The preceding identification identifies the material carried by the carrier to determine whether it is raw or cooked material, so as to perform preliminary screening of raw and cooked materials; This process involves first reading the unique identifier of each material, and then matching and comparing that material with the material process status bound to the production system to achieve preliminary screening of raw and processed materials. For example, as materials pass through, the unique identifier of the material is simultaneously read using barcode scanning or card reading, and then uploaded to the data processing center of the production system. This data is then preliminarily determined and categorized as "raw materials to be produced," "qualified processed materials," or "suspected erroneous materials," etc. This not only completes the preliminary screening of raw and processed materials but also provides further priority screening guidance. For example, "suspected erroneous materials" can be further screened and confirmed, thereby improving the control of production quality through material screening and testing.
[0034] For example, unsoldered PCBs are considered "raw materials to be produced", soldered PCBs are considered "qualified finished materials", and materials that do not match the process status are considered "suspected error materials".
[0035] S5: If the initial screening determines that there is an incorrect transfer of raw materials and clinker, the corresponding carriers will be diverted to the material verification process. The determination of "suspected incorrect materials" requires a second material review, such as reconfirming the attribution of "suspected incorrect materials" through manual verification or a material review agency.
[0036] S6: If the preliminary screening determines that there is no incorrect transfer of raw or clinker materials, then the corresponding vehicle is allowed to enter the outer or inner production line.
[0037] Furthermore, in this embodiment, after preliminary screening of raw materials and clinker, before the corresponding carriers enter the outer or inner production line, the production line carrier allocation method further includes: S7: Based on multidimensional characteristic detection, identify the appearance and structure of raw or clinker after initial screening, so as to conduct secondary screening of raw and clinker; Further determination will be made regarding "suspected incorrect materials" to increase the accuracy of material identification and thus ensure the smooth progress of subsequent production.
[0038] Multidimensional characteristic detection, for example, can distinguish the characteristics of raw or cooked materials based on their appearance and structure, thereby further determining whether the material carried by the carrier is raw, cooked, or other unrelated material, thus improving the accuracy of raw and cooked material screening.
[0039] S8: If the second screening determines that there is an incorrect transfer of raw materials and clinker, the corresponding carriers will be diverted to enter the material verification process. After verification and adjustment, the corresponding carriers will enter the outer or inner production line. S9: If, after secondary screening, it is determined that there is no incorrect transfer of raw or clinker materials, then the corresponding carrier is allowed to enter the outer or inner production line.
[0040] Example 2: When an automated production line is configured with three identical production units, the three production units are interconnected via a carrier transfer mechanism. Corresponding inlet and outlet ends are also equipped with carrier transfer mechanisms, thereby achieving the following: Figure 6 , 7 The rapid assembly of the production line shown Figure 6 , 7 Both adopt a dual production line layout of working line and branch line.
[0041] In this embodiment, the carrier allocation logic for the parallel production lines of each production unit is understood as follows: like Figure 6 As shown, during normal production, each production unit 1 has one raw material in operation and one raw material waiting to be processed on its internal assembly line; each production unit 1's external assembly line dynamically maintains two carriers; and the production unit 2's external assembly line maintains one raw material ready to be supplied to production unit 3.
[0042] like Figure 7 As shown, during abnormal production, after the production unit 1 malfunctions, the internal production line of the production unit 1 stops sending material request signals to the carrier transfer mechanism 1, and the carrier transfer mechanism 1 no longer distributes raw materials to the internal production line of the malfunctioning production unit 1. The other functions of the production unit 1 operate normally.
[0043] This example only illustrates the abnormal failure of production unit 1; the same principle applies to abnormal failures in production units 2 and 3.
[0044] Example 3: This application also provides a production line system. This production line system applies the production line carrier allocation method provided in Example 1. Through the cooperation of the corresponding mechanisms and production lines in the production line system, the carrier flow direction is reasonably changed to adjust the direction of raw materials or cooked materials, and to avoid production units with abnormal production in a timely manner, so as to ensure the smooth production of production units with normal production, thereby ensuring the operation of the entire automated production line.
[0045] Specifically, in this embodiment, the assembly line production system includes: The parallel production lines include an outer production line 10 and an inner production line 20; wherein, the outlet position of the outer production line 10 is equipped with a lifting buffer mechanism 30; when the next production unit experiences a production anomaly, the raw materials are temporarily stored by the lifting buffer mechanism 30.
[0046] Each production unit is equipped with a carrier transfer mechanism at both the inlet and outlet ends. When a single production unit experiences a production malfunction, the carrier transfer mechanism transfers the carrier carrying raw or cooked materials to the next production unit, ensuring the normal production of subsequent production units.
[0047] It is understandable that a production unit refers to a processing unit that works in conjunction with production equipment and assembly lines.
[0048] Furthermore, in this embodiment, the assembly line production system also includes: The preceding identification mechanism is used to identify the materials carried by the preceding identification vehicle to determine whether they are raw or cooked materials, so as to perform preliminary screening of raw and cooked materials; The material verification mechanism is used to verify the materials carried by the vehicle. The diversion mechanism is used to divert the carrier to the material verification process.
[0049] Among them, the preceding identification mechanism is such as a barcode scanner or RFID reader; the material verification mechanism is such as a visual recognition camera module; and the diversion mechanism is such as a diversion conveyor belt module.
[0050] Furthermore, in this embodiment, the assembly line production system also includes: Multidimensional property testing institutions are used to identify the appearance and structure of raw or clinker after initial screening based on multidimensional property testing, so as to conduct secondary screening of raw and clinker.
[0051] Among them, the multi-dimensional feature detection mechanism consists of, for example, 3D laser cameras, 4K industrial cameras, edge computing modules, laser sensors, etc., to realize multi-dimensional appearance and structure detection such as visual recognition detection and laser contour detection.
[0052] It should be understood that ordinary skilled workers in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
