Description

Technical Field

[0001] This invention relates to a production line technology, and more specifically, to a control method for a continuous production line. Background Technology

[0002] In the field of modern mechanical manufacturing, the connecting rod is a core transmission component of equipment such as internal combustion engines and compressors, and its machining accuracy directly affects the performance of the whole machine.

[0003] Traditional connecting rod production often adopts a discrete process processing mode, which has three major technical bottlenecks: First, the material transfer between processes relies on manual intervention, resulting in an average of 2-3 hours of non-value-added time per shift; second, the processing parameters are set independently for each machine, and the coordination error of process parameters between different equipment can reach ±0.05mm; third, quality inspection lags behind the processing process, and the average traceability time for defective products exceeds 45 minutes. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a control method for a continuous production line.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a control method for a continuous production line, comprising a plurality of processing devices arranged in a linear array for processing connecting rods, a conveying device disposed on the finished product outlet side of each processing device for conveying the finished connecting rods to a conveying device, a conveying device disposed in front of the plurality of processing devices for receiving the finished connecting rods conveyed by the conveying device and conveying them to a connecting rod collection area, and a control system for controlling the coordinated operation of the devices, the control method comprising the following steps:

[0006] S1. The control system sends a start command to all processing devices, controlling each processing device to start processing the connecting rod according to the preset processing parameters. At the same time, it sends a run command to the conveying device, controlling the conveying device to start running at the preset speed V1.

[0007] S2. Each processing device collects its own processing progress data in real time during the processing. When the processing progress data reaches the preset processing completion threshold, it sends a processing completion signal to the control system. After receiving the processing completion signal, the control system executes S3.

[0008] S3. The control system sends a start signal to the conveyor corresponding to the processing device, controls the conveyor to start running at a preset speed V2, and simultaneously starts the first position detection module on the conveyor.

[0009] S4. The first position detection module detects in real time whether the connecting rod has moved from the processing device to the bearing area of ​​the conveying device. If the connecting rod is detected to have reached the bearing area, the first position signal is sent to the control system. After receiving the first position signal, the control system executes S5. If the first position signal is not detected within the time period T1, the conveying device is controlled to stop operating and the corresponding processing device is controlled to suspend processing and issue a conveying abnormality prompt.

[0010] S5. The control system controls the conveying device to keep it running and simultaneously activates the second position detection module on the conveying device. The second position detection module detects in real time whether the connecting rod has moved from the bearing area of ​​the conveying device to the docking area between the conveying device and the conveying device.

[0011] S6. If the second position detection module detects that the connecting rod has reached the docking area, it sends a second positioning signal to the control system. After receiving the second positioning signal, the control system controls the conveying device to adjust its operating speed to V3 and starts the third position detection module on the conveying device. If the second positioning signal is not detected within the T2 time period, the control system controls the conveying device to run in the reverse direction for a preset distance and then run in the forward direction again. If the second positioning signal is not detected again, the control system stops the conveying device and controls the corresponding processing device to suspend processing and issue a docking abnormality prompt.

[0012] S7. The third position detection module detects in real time whether the connecting rod has moved from the docking area of ​​the conveying device to the conveying area of ​​the conveying device. If the connecting rod is detected to have reached the conveying area, a third position signal is sent to the control system. After receiving the third position signal, the control system controls the conveying device to stop operating and return to its initial position. At the same time, the control system controls the conveying device to keep operating and convey the connecting rod to the connecting rod collection area. If the third position signal is not detected within the T3 time period, the conveying device continues to operate to ensure that the connecting rods conveyed to the conveying device by the other conveying devices can be conveyed to the connecting rod collection area. The corresponding conveying device is controlled to stop operating and the corresponding processing device is controlled to suspend processing, and a conveying abnormality prompt is issued.

[0013] The present invention is further configured such that, in step S6, the ratio of the operating speed V3 to the preset speed V2 is adjusted to 0.8-0.9:1.

[0014] The present invention is further configured such that: in step S4, when the first position detection module detects whether the connecting rod has reached the bearing area, it also makes a judgment based on the pressure data collected by the pressure detection module of the conveying device, including: after the first position detection module detects the position signal of the connecting rod, the pressure detection module collects the real-time pressure value P of the bearing area of ​​the conveying device, compares the real-time pressure value P with the preset pressure threshold P0, if P∈[P0-R1,P0+R1], where R1 is the preset pressure fluctuation threshold, then it is determined that the connecting rod has reached the bearing area and a first positioning signal is sent; if P<P0-R1, then it is determined that the connecting rod has not been fully placed in place, and the conveying device is controlled to fine-tune its position and re-detect; if P>P0+R1, then it is determined that the bearing of the conveying device is abnormal, the conveying device is stopped and the corresponding processing device is controlled to suspend processing and issue an overload warning.

[0015] The present invention is further configured such that: in step S5, when the second position detection module detects whether the connecting rod has reached the docking area, it also makes a comprehensive judgment based on the displacement data collected by the displacement sensor of the conveying device and the real-time speed data collected by the speed sensor. Specifically, the displacement sensor collects the real-time displacement value S of the conveying device and the speed sensor collects the real-time speed value V of the conveying device. The control system calculates the estimated time Tpre for the connecting rod to reach the docking area based on the real-time displacement value S and the real-time speed value V. Tpre is compared with the preset standard time Tstandard. If |Tpre - Tstandard| ≤ R2, where R2 is the preset time deviation threshold, the detection continues through the second position detection module. If |Tpre - Tstandard| > R2, the operating speed of the conveying device is adjusted until |Tpre - Tstandard| ≤ R2. If the adjustment fails to meet the requirement of |Tpre - Tstandard| ≤ R2 after 3 adjustments, the conveying device is stopped and the corresponding processing device is controlled to suspend processing and issue a speed abnormality warning.

[0016] The present invention is further configured such that: in step S2, the processing progress data includes processing time, cutting depth and processing temperature, and the preset processing completion threshold includes a preset processing time threshold, a preset cutting depth threshold and a preset processing temperature stability threshold. When the processing time reaches the preset processing time threshold, the cutting depth reaches the preset cutting depth threshold and the processing temperature is stable within the preset processing temperature stability threshold range, it is determined that the processing progress data has reached the preset processing completion threshold.

[0017] The present invention is further configured such that: the conveying device includes a support platform for supporting the connecting rod, a drive motor for driving the support platform to move, a first position detection module and a second position detection module for detecting the position of the connecting rod, the support platform is provided with a positioning protrusion for blocking the connecting rod and preventing it from falling, the drive motor is electrically connected to the control system, and the control system adjusts the operating speed of the conveying device by controlling the rotation speed of the drive motor.

[0018] The conveying device includes a conveyor belt for conveying the connecting rod, a conveyor motor for driving the conveyor belt, and a third position detection module for detecting the position of the connecting rod. The surface of the conveyor belt is provided with anti-slip texture. The conveyor motor is electrically connected to the control system. The control system adjusts the operating speed of the conveying device by controlling the output power of the conveyor motor.

[0019] The beneficial effects of this invention are:

[0020] 1. Compared with existing technologies, the control method for continuous production lines of this invention achieves automated continuous operation of the connecting rod production line by setting up processing devices, conveying devices, conveying devices, and a control system; by collecting processing progress data in real time and combining it with multi-position detection modules, it ensures precise connection of each link and reduces manual intervention; by setting up a multi-level anomaly detection and handling mechanism, it can respond in a timely manner when anomalies occur in the conveying, docking, and conveying links, avoiding the expansion of faults and ensuring production stability; at the same time, through speed control and process optimization, it improves overall production efficiency, is suitable for large-scale continuous production scenarios, and reduces the risk of production interruption and labor costs.

[0021] 2. In the control method of the continuous production line of the present invention, adjusting the ratio of the operating speed V3 to the preset speed V2 to 0.8-0.9:1 can reduce the speed when the connecting rod is about to enter the conveying device, reduce the impact when the connecting rod docks with the conveying device, avoid the position displacement or damage of the connecting rod caused by high-speed collision, and improve the docking accuracy. At the same time, moderate deceleration can reserve buffer time for the subsequent conveying device to receive the connecting rod, ensure that the motion states of the two are matched, reduce the probability of docking failure, further ensure the smooth operation of the production line, and reduce production stoppage caused by docking problems.

[0022] 3. In this invention, the pressure detection module is used to determine whether the connecting rod is in place, which is more accurate than single-position detection. By comparing the pressure value with a preset threshold, problems such as incomplete placement of the connecting rod or overload can be effectively identified. When the pressure is abnormal, the position is finely adjusted or the machine is stopped in time to avoid transmission jamming or damage caused by improper placement of the connecting rod, thereby improving transmission reliability. At the same time, the pressure detection provides a quantitative basis for the load-bearing state of the connecting rod, ensuring that the connecting rod is subjected to balanced force during transmission, reducing deformation caused by uneven force, and ensuring the quality of the finished product.

[0023] 4. In this invention, the position of the connecting rod is determined by combining displacement and velocity data. By calculating the expected arrival time and comparing it with the standard time, abnormal transmission speeds can be detected in advance. The speed can be adjusted in time to keep the time deviation within a reasonable range, ensuring that the connecting rod arrives at the docking area as expected, thus improving docking accuracy. When multiple adjustments still fail to meet the standard, a shutdown prompt is issued to avoid continuous docking failures caused by abnormal speeds, reduce ineffective transmission, and minimize the impact on overall production efficiency. This dynamic control mechanism enhances the adaptability of the transmission device, enabling it to cope with factors such as equipment wear and load changes, and ensuring transmission stability.

[0024] Figure 1 This is a flowchart of the control method for a continuous production line according to the present invention. Detailed Implementation

[0025] Reference Figure 1 The embodiments of the control method for the continuous production line of the present invention will be further described.

[0026] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0028] Figure 1 The control method for a continuous production line shown includes several processing devices arranged in a linear array for processing connecting rods; a conveying device located at the finished product outlet side of each processing device for conveying the finished connecting rods to a conveying device; a conveying device located in front of several processing devices for receiving the finished connecting rods conveyed by the conveying device and conveying them to a connecting rod collection area; and a control system for controlling the coordinated operation of the devices. The control method includes the following steps:

[0029] S1. The control system sends a start command to all processing devices, controlling each processing device to start processing the connecting rod according to the preset processing parameters. At the same time, it sends a run command to the conveying device, controlling the conveying device to start running at the preset speed V1.

[0030] S2. Each processing device collects its own processing progress data in real time during the processing. When the processing progress data reaches the preset processing completion threshold, it sends a processing completion signal to the control system. After receiving the processing completion signal, the control system executes S3.

[0031] S3. The control system sends a start signal to the conveyor corresponding to the processing device, controls the conveyor to start running at a preset speed V2, and simultaneously starts the first position detection module on the conveyor.

[0032] S4. The first position detection module detects in real time whether the connecting rod has moved from the processing device to the bearing area of ​​the conveying device. If the connecting rod is detected to have reached the bearing area, the first position signal is sent to the control system. After receiving the first position signal, the control system executes S5. If the first position signal is not detected within the time period T1, the conveying device is controlled to stop operating and the corresponding processing device is controlled to suspend processing and issue a conveying abnormality prompt.

[0033] S5. The control system controls the conveying device to keep it running and simultaneously activates the second position detection module on the conveying device. The second position detection module detects in real time whether the connecting rod has moved from the bearing area of ​​the conveying device to the docking area between the conveying device and the conveying device.

[0034] S6. If the second position detection module detects that the connecting rod has reached the docking area, it sends a second positioning signal to the control system. After receiving the second positioning signal, the control system controls the conveying device to adjust its operating speed to V3 and starts the third position detection module on the conveying device. If the second positioning signal is not detected within the T2 time period, the control system controls the conveying device to run in the reverse direction for a preset distance and then run in the forward direction again. If the second positioning signal is not detected again, the control system stops the conveying device and controls the corresponding processing device to suspend processing and issue a docking abnormality prompt.

[0035] S7. The third position detection module detects in real time whether the connecting rod has moved from the docking area of ​​the conveying device to the conveying area of ​​the conveying device. If the connecting rod is detected to have reached the conveying area, it sends a third position signal to the control system. After receiving the third position signal, the control system controls the conveying device to stop operating and return to the initial position. At the same time, it controls the conveying device to keep operating and convey the connecting rod to the connecting rod collection area. If the third position signal is not detected within the T3 time period, the conveying device continues to operate to ensure that the connecting rods conveyed to the conveying device by the other conveying devices can be conveyed to the connecting rod collection area. It controls the corresponding conveying device to stop operating and controls the corresponding processing device to suspend processing, and issues a conveying abnormality prompt.

[0036] Compared to existing technologies, the control method for continuous production lines of this invention achieves automated continuous operation of the connecting rod production line by setting up processing devices, conveying devices, transporting devices, and a control system. By collecting processing progress data in real time and combining it with multi-position detection modules, it ensures precise connection of each link and reduces manual intervention. By setting up a multi-level anomaly detection and handling mechanism, it can respond promptly when anomalies occur in the conveying, docking, and transporting links, preventing the fault from escalating and ensuring production stability. At the same time, through speed control and process optimization, it improves overall production efficiency, is suitable for large-scale continuous production scenarios, and reduces the risk of production interruption and labor costs.

[0037] In step S6, the ratio of the operating speed V3 to the preset speed V2 is adjusted to 0.8-0.9:1;

[0038] Adjusting the ratio of operating speed V3 to preset speed V2 to 0.8-0.9:1 can reduce the speed when the connecting rod is about to enter the conveyor, reducing the impact when the connecting rod docks with the conveyor, avoiding positional displacement or damage to the connecting rod due to high-speed collision, and improving docking accuracy. At the same time, moderate deceleration can reserve buffer time for the subsequent conveyor to receive the connecting rod, ensuring that the motion states of the two are matched, reducing the probability of docking failure, further ensuring the smooth operation of the production line, and reducing production stoppages caused by docking problems.

[0039] In step S4, when the first position detection module detects whether the connecting rod has reached the bearing area, it also combines the pressure data collected by the pressure detection module of the conveying device for judgment, including: after the first position detection module detects the position signal of the connecting rod, the pressure detection module collects the real-time pressure value P of the bearing area of ​​the conveying device, compares the real-time pressure value P with the preset pressure threshold P0, if P∈[P0-R1,P0+R1], where R1 is the preset pressure fluctuation threshold, then it is determined that the connecting rod has reached the bearing area and a first positioning signal is sent; if P<P0-R1, then it is determined that the connecting rod has not been fully placed in place, and the conveying device is controlled to fine-tune the position and re-detect; if P>P0+R1, then it is determined that the bearing of the conveying device is abnormal, the conveying device is stopped and the corresponding processing device is controlled to suspend processing and issue an overload warning.

[0040] The pressure detection module is more accurate than single-position detection in determining whether the connecting rod is in place. By comparing the pressure value with a preset threshold, it can effectively identify problems such as incomplete rod placement or overload. When the pressure is abnormal, it can promptly fine-tune the position or issue a shutdown warning to avoid transmission jams or damage caused by improper rod placement, thus improving transmission reliability. At the same time, the pressure detection provides a quantitative basis for the load-bearing state of the connecting rod, ensuring that the connecting rod is subjected to balanced force during transmission, reducing deformation caused by uneven force, and ensuring the quality of the finished product.

[0041] In step S5, when the second position detection module detects whether the connecting rod has reached the docking area, it also makes a comprehensive judgment based on the displacement data collected by the displacement sensor of the conveying device and the real-time speed data collected by the speed sensor. Specifically, the displacement sensor collects the real-time displacement value S of the conveying device and the speed sensor collects the real-time speed value V of the conveying device. The control system calculates the estimated time Tpre for the connecting rod to reach the docking area based on the real-time displacement value S and the real-time speed value V. It compares Tpre with the preset standard time Tstandard. If |Tpre - Tstandard| ≤ R2, where R2 is the preset time deviation threshold, the second position detection module continues to detect. If |Tpre - Tstandard| > R2, the operating speed of the conveying device is adjusted until |Tpre - Tstandard| ≤ R2. If the adjustment fails to meet the requirement of |Tpre - Tstandard| ≤ R2 after 3 adjustments, the conveying device is stopped and the corresponding processing device is controlled to suspend processing and issue a speed abnormality warning.

[0042] By combining displacement and velocity data to comprehensively determine the position of the connecting rod, and calculating the estimated arrival time and comparing it with the standard time, abnormal transmission speeds can be detected in advance. Timely speed adjustments can be made to keep the time deviation within a reasonable range, ensuring that the connecting rod arrives at the docking area as expected, thus improving docking accuracy. When multiple adjustments still fail to meet the standard, a shutdown prompt can be issued to avoid continuous docking failures caused by abnormal speeds, reduce ineffective transmissions, and minimize impact on overall production efficiency. This dynamic control mechanism enhances the adaptability of the transmission device, enabling it to cope with factors such as equipment wear and load changes, and ensuring transmission stability.

[0043] In step S2, the processing progress data includes processing time, cutting depth and processing temperature. The preset processing completion threshold includes a preset processing time threshold, a preset cutting depth threshold and a preset processing temperature stability threshold. When the processing time reaches the preset processing time threshold, the cutting depth reaches the preset cutting depth threshold and the processing temperature is stable within the preset processing temperature stability threshold range, it is determined that the processing progress data has reached the preset processing completion threshold.

[0044] By using machining time, depth of cut, and machining temperature as criteria for judging machining progress, multiple controls on the machining quality of connecting rods are achieved. Machining time ensures sufficient machining process, depth of cut guarantees dimensional accuracy, and stable machining temperature ensures consistent machining quality. Machining is considered complete only when all three parameters meet the standards, avoiding the outflow of defective products due to misjudgment of a single indicator and improving the finished product pass rate. At the same time, multi-parameter monitoring can promptly detect abnormalities in the machining process, providing data support for subsequent process optimization and improving overall production quality.

[0045] The conveying device includes a support platform for supporting the connecting rod, a drive motor for driving the support platform to move, a first position detection module and a second position detection module for detecting the position of the connecting rod. The support platform is provided with a positioning protrusion for blocking the connecting rod and preventing it from falling. The drive motor is electrically connected to the control system, and the control system adjusts the operating speed of the conveying device by controlling the rotation speed of the drive motor.

[0046] The conveying device includes a conveyor belt for conveying the connecting rod, a conveyor motor for driving the conveyor belt, and a third position detection module for detecting the position of the connecting rod. The surface of the conveyor belt is provided with anti-slip texture. The conveyor motor is electrically connected to the control system. The control system adjusts the operating speed of the conveying device by controlling the output power of the conveyor motor.

[0047] The positioning protrusions of the conveyor effectively prevent the connecting rod from falling off during conveying, and the speed regulation function of the drive motor meets the conveying needs of different stages, improving the stability of conveying. The anti-slip texture of the conveyor increases friction and prevents the connecting rod from sliding during conveying. This structural design, in conjunction with the control system, achieves precise positioning and smooth movement of the connecting rod during conveying and transporting, reducing product damage or conveying errors caused by equipment structural defects, extending equipment service life, reducing maintenance costs, and ensuring efficient operation of the production line.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
