Description

TECHNICAL FIELD

[0001] The present application relates to the field of thread rolling machine processing, in particular to a vehicle rearview mirror rod thread rolling machine control device and method. BACKGROUND

[0002] The thread rolling machine is a machine tool that forms threads on pipes by pressure. It uses a rolling wheel to continuously roll on metal wire, causing plastic deformation of the metal wire, thereby obtaining metal wire of the desired shape and size.

[0003] With the development of industrial production, the requirements for processing efficiency and precision are increasing, and automation technology is introduced into the field of thread rolling machines. By adding an automatic feeding mechanism and an automatic control system, automatic feeding, positioning and processing of pipes are realized.

[0004] In view of the above related technology, the current thread rolling machine processing link is prone to blockage of the feeding area of the processed pipe, which prevents the processed pipe in the feeding area from being processed, and manual adjustment of the position of the processed pipe in the feeding area is required, affecting the subsequent processing efficiency. SUMMARY

[0005] In order to realize that the feeding area of the thread rolling machine will not be blocked during the processing process, the present application provides a vehicle rearview mirror rod thread rolling machine control device and method.

[0006] In the first aspect, the present application provides a vehicle rearview mirror rod thread rolling machine control device, which adopts the following technical scheme: A vehicle rearview mirror rod thread rolling machine control device, comprising a driving assembly, a support base, a processing assembly, and a feeding assembly, the feeding assembly comprising a limiting plate, a first feeding plate, a connecting column, a second feeding plate, a first pushing assembly, and an abutting block; The driving assembly is fixedly installed on one side of the support base and fixedly connected with the processing assembly. The processing assembly is installed on the side of the support base away from the driving assembly. The limiting plate is arranged on the side of the support base away from the driving assembly and above the processing assembly. The abutting block is arranged on one side of the limiting plate and forms a first discharging groove and a feeding area with the limiting plate. One end of the first feeding plate close to the support base is fixedly connected with one end of the connecting column. The other end of the connecting column is fixedly connected with the second feeding plate. The second feeding plate is fixedly connected with the first pushing assembly. The second feeding plate forms a second discharging groove with the limiting plate. The driving assembly controls the upward movement of the processing assembly during rotation. The abutting block moves upward during the upward movement of the processing assembly, prompting the first pushing assembly connected with the abutting block to push the processed pipe in the feeding area.

[0007] By adopting the technical scheme, the driving assembly provides power for the whole device, ensures that the machining assembly can move according to a predetermined track and force, and thus realizes accurate machining of the pipe fitting. The feeding assembly is responsible for accurately conveying the pipe fitting to be machined to a machining position, and the setting of the limiting plate effectively prevents deviation of the pipe fitting during conveying, thereby ensuring the stability of machining. The first feeding plate and the second feeding plate are fixedly connected through the connecting column, forming a stable structure, and cooperating with the first pushing assembly to realize automatic pushing of the pipe fitting to be machined. The unloading groove and the feeding area formed by the abutting block and the limiting plate enable the pipe fitting to be sequentially unloaded and loaded, thereby avoiding the occurrence of the jamming phenomenon.

[0008] Optionally, the device further comprises a second pushing assembly, a lifting assembly, an unloading container and a recycling container. The second pushing assembly is fixedly installed on one side of the first pushing assembly close to the limiting plate and can push the pipe fitting to be machined along the length direction of the first feeding plate during movement of the first pushing assembly. The lifting assembly is slidably connected to one side of the limiting plate close to the first feeding plate and is used to lift the pipe fitting to be machined located in the first unloading groove. The unloading container is arranged at one end of the supporting base close to the machining assembly and is located directly below the first unloading groove, and is used to receive the pipe fitting to be machined that has been machined in the feeding area. The recycling container is arranged at one end of the supporting base close to the machining assembly and is located next to the unloading container, and is used to receive the unqualified pipe fitting to be machined.

[0009] By adopting the technical scheme, the second pushing assembly further enhances the automation processing capability of the device. It can push the pipe fitting to be machined along the length direction of the first feeding plate during movement of the first pushing assembly, effectively solving the problem of poor feeding caused by close arrangement or irregular shape of the pipe fitting. The design of the lifting assembly reflects the flexibility of the device in handling abnormal situations. It can be slidably connected to one side of the limiting plate close to the first feeding plate, and can lift the pipe fitting to be machined located in the first unloading groove as needed, thereby avoiding interruption of machining caused by accumulation or poor unloading of the pipe fitting, and ensuring continuity and stability of the production process.

[0010] In a second aspect, the present application provides a vehicle rearview mirror rod thread rolling machine control method, which adopts the following technical scheme: A vehicle rearview mirror rod thread rolling machine control method, comprising: S1: obtaining an unloading area video; S2: analyzing the unloading area video to obtain a pipe fitting machining speed; S3: when the pipe fitting machining speed is 0, obtaining the weight of the pipe fitting to be machined in the feeding area; S4: determining the blockage state of the feeding area when the weight of the pipe to be processed is not 0, and controlling the second pushing assembly to perform a pushing operation based on a preset blockage pushing scheme until the pipe processing speed is not equal to 0.

[0011] By adopting the above technical solution, the system can monitor the processing state of the pipe in real time by acquiring the video of the discharging area, and then accurately obtain the pipe processing speed. When the pipe processing speed is 0, the system further acquires the weight of the pipe to be processed in the feeding area. If the weight of the pipe to be processed in the feeding area is not 0 at this time, it can be determined that the feeding area has been blocked. The system controls the pushing assembly to perform a pushing operation to restore the normal flow of the feeding area and ensure the continuous and stable operation of the thread rolling machine. This control method effectively improves the automation degree and processing efficiency of the thread rolling machine and reduces the need for manual intervention.

[0012] Optionally, it further comprises: S5: accumulating the number of continuous pushing operations after the pushing operation is completed; S6: performing a lifting operation when the number of continuous pushing operations is greater than a preset maximum pushing operation number threshold, the lifting operation being lifting the pipe to be processed in the feeding area by the lifting assembly to control the pipe to be processed in the first discharging groove to fall into the feeding area; S7: repeating the lifting operation when the pipe processing speed is still 0 after the lifting operation is performed, and accumulating the number of lifting operations until the pipe processing speed is not 0; S8: outputting a preset equipment abnormal signal when the number of lifting operations is greater than a preset maximum lifting operation number threshold.

[0013] By adopting the above technical solution, the system will accumulate the number of continuous pushing operations after each pushing operation is completed. When this number exceeds the preset maximum pushing operation number threshold, the system will determine that the current blockage is more serious, and the conventional pushing operation may not be able to effectively solve the problem. At this time, the system will perform a lifting operation, that is, control the pipe to be processed in the feeding area to be lifted, the purpose being to make the pipe to be processed in the first discharging groove fall into the feeding area, thereby changing the stacking state of the pipe and possibly solving the blockage problem. The design of this operation aims to solve the blockage problem of the feeding area as much as possible through automation, thereby improving the running efficiency and stability of the equipment.

[0014] Optionally, it further comprises: S9: acquiring the pushing speed when the pushing operation is performed; S10: controlling the second pushing assembly to perform a preset correction pushing operation until the pipe processing speed is not 0 when the pushing speed of the second pushing assembly is 0 within a preset single pushing time; S11: Accumulate the length of the correction pushing operation when the correction pushing operation is performed; S12: Output a preset alarm signal when the length of the correction pushing operation is greater than a preset single correction pushing length.

[0015] By adopting the above technical solution, when the system is performing the pushing operation, the pushing speed is obtained in real time. If the pushing speed of the second pushing component is continuously 0 within the preset single pushing length, it indicates that the pipe in the feeding area may be blocked, and the current pushing operation cannot produce an effect, so the system immediately controls the second pushing component to perform the preset correction pushing operation. The design of this shaking method effectively improves the response capability of the system when the pushing operation fails, and reduces the production interruption caused by equipment failure.

[0016] Optionally, it also includes a method for determining the lifting number, which includes: S13: Obtain the marker image when the lifting operation is performed; S14: Analyze the marker image to determine the marker pipe number; S15: Define the marker pipe number as the lifting number.

[0017] By adopting the above technical solution, in the process of performing the lifting operation, the system obtains the image of the workpiece in the first discharge chute. These marker images are special markers made on the pipe by the second pushing component when the lifting operation occurs. To facilitate observation of the effective lifting number, the second pushing component updates the marker position every time the lifting operation is performed. When an abnormal workpiece occurs, after each lifting, the abnormal workpiece falls into the first discharge chute, so the lifting number is one lifting number. If there is a second abnormal workpiece, the lifting number is two lifting numbers. This method not only improves the accuracy of the lifting number statistics, but also provides reliable data support for subsequent equipment maintenance and troubleshooting. At the same time, since the marker image is obtained in real time during lifting, it can truly reflect the actual lifting of the pipe, which helps to discover and solve potential blockage problems in a timely manner.

[0018] Optionally, it also includes a processing optimization method for the feeding area when the marker pipe number exists, which includes: S16: Based on the marker image analysis, the number of markers attached to a single workpiece to be processed is obtained, and is defined as the abnormal marker number; S17: Determine the abnormal pipe when the abnormal marker number is greater than a preset maximum abnormal marker number; S18: Obtain the image of the feeding area, and determine the position of the abnormal pipe based on the image of the feeding area; S19: When the abnormal pipe position falls into the preset to-be-discharged area, an abnormal pipe pushing scheme is formed based on the abnormal pipe position, and the second pushing assembly is controlled to push the abnormal pipe according to the abnormal pipe pushing scheme until the abnormal pipe does not exist in the feeding area.

[0019] By adopting the above technical solution, when the system detects the existence of the marked pipe, the abnormal marking quantity of the single pipe is obtained. Once the abnormal marking quantity exceeds the maximum abnormal marking quantity threshold preset by the system, the system determines that the pipe is an abnormal pipe, and then controls the second pushing assembly to lift the abnormal pipe away from the first discharge notch to avoid the first discharge notch being blocked.

[0020] Optionally, the method further comprises recycling the abnormal pipe, and the method comprises: S20: determining a recycling position according to the feeding area image; S21: determining a pipe to be recycled when the abnormal pipe position falls into the recycling position; S22: when the pipe to be recycled exists and the device abnormal signal does not exist, controlling the second pushing assembly to perform a recycling operation based on the recycling position and a preset recycling scheme, the recycling operation being lifting the pipe to be recycled by the second pushing assembly and making the pipe to be recycled leave the feeding area.

[0021] By adopting the above technical solution, the system can carefully analyze the feeding area image based on the position of the abnormal pipe and the recycling position, so as to accurately lock the pipe to be recycled. In the case where the recycling pipe exists and the device does not send an abnormal signal, the system further acquires the specific position of the recycling pipe. Then, according to the preset recycling scheme, the system instructs the second pushing assembly to perform the recycling operation, that is, the second pushing assembly lifts the pipe to be recycled and ensures that it leaves the feeding area smoothly. This series of operations not only realizes the automatic recycling of the abnormal pipe, but also effectively avoids the possible processing interruption or device failure caused by the long-term stay of the abnormal pipe in the feeding area.

[0022] Optionally, when the lifting frequency is greater than the maximum lifting operation frequency threshold, the method of outputting the device abnormal signal comprises: S23: determining a foreign matter blockage when the lifting frequency is greater than the maximum lifting operation frequency threshold; S24: based on the foreign matter blockage, searching for a preset foreign matter pushing scheme, and controlling the lifting assembly to perform a lifting operation based on the foreign matter pushing scheme; S25: outputting the device abnormal signal if the pipe processing speed is still 0 after the lifting assembly performs the lifting operation.

[0023] By adopting the technical scheme, when the system detects that the lifting frequency exceeds the preset maximum lifting operation frequency threshold, it will first determine that it is a foreign matter blockage condition. At this time, the system will control the second pushing assembly to perform the lifting operation to try to clean the impurities in the first blanking notch to eliminate the blockage problem. If the machining speed of the pipe fitting is still 0 after the lifting operation is performed, it means that the blockage problem has not been solved, at this time, the system will output an equipment abnormal signal to prompt the operator to check and manually intervene. This design not only improves the system's ability to cope with complex blockage conditions, but also reduces the workload of manual inspection through automated preliminary processing, thereby improving the overall production efficiency.

[0024] The method for cleaning the feeding area comprises: S26: Obtain a feeding area image, and analyze based on the feeding area image to obtain a feeding area feature; S27: Determine a feeding area idle state according to the feeding area feature; S28: When the feeding area idle state exists, control the second pushing assembly to perform a cleaning pushing operation based on a preset cleaning pushing scheme; S29: During the execution of the cleaning pushing operation of the second pushing assembly, obtain a pushing speed of the second pushing assembly in real time, and define the pushing speed as a cleaning speed; S30: When the cleaning speed is 0, pause the cleaning pushing operation, and output a preset manual cleaning signal.

[0025] By adopting the technical scheme, the system can obtain the image of the feeding area, analyze the feature to determine whether there is an idle state at present. When it is confirmed that the feeding area is in an idle state, the system will be based on the preset cleaning pushing scheme. During the cleaning process, the system will monitor the pushing speed of the second pushing assembly in real time, and define the pushing speed as the cleaning speed. If the cleaning speed decreases to 0, it means that there may be stubborn residues or foreign matters that hinder the cleaning process. At this time, the system will automatically pause the cleaning pushing operation and output a manual cleaning signal to prompt the operator to manually clean. Ensure that the feeding area is always unblocked, thereby improving the overall operation efficiency and stability of the equipment.

[0026] In summary, the present application has the following at least one beneficial technical effect: Different pushing schemes are designed for different degrees of blockage to solve the blockage problem of the feeding area and significantly improve the continuous machining efficiency; The red dye marked locking abnormal pipe fitting is used to determine the equipment problem and the pipe fitting problem, when the pipe fitting problem occurs, the YOLO algorithm is used for positioning, and then the second pushing assembly lifts the pipe fitting away from the blanking area and the feeding area, thereby reducing the blockage frequency; When an abnormal pipe fitting appears, the second pushing assembly is controlled to perform a recycling operation by identifying the recycling position and a preset recycling scheme, and other pipe fittings are not affected, effectively avoiding the possible processing interruption or equipment failure caused by the long-term stay of the abnormal pipe fitting in the feeding area.

DETAILED DESCRIPTION

[0029] The present application will be further described in detail below in combination with the drawings and embodiments.

[0030] The present application discloses a vehicle rearview mirror rod thread rolling machine control device and method. Embodiment 1

[0031] Refer toFigure 1 The vehicle rearview mirror rod thread rolling machine control device comprises a driving assembly 1, a supporting base 2, a processing assembly 3, and a feeding assembly 4. Figure 2 and Figure 3 The feeding assembly 4 comprises a limiting plate 41, a first feeding plate 42, a connecting column 43, a second feeding plate 44, a first pushing assembly 45, and an abutting block 46.

[0032] Referring to Figure 3 The first pushing assembly 45 comprises a sliding sheet 451, a first connecting rod 452, a second connecting rod 453, a third connecting rod 454, a first rotating shaft 455, a first pushing rod 456, and a first pushing plate 457.

[0033] The driving assembly 1 is fixedly installed on one side of the supporting base 2 and fixedly connected with the processing assembly 3. The side of the supporting base 2 away from the driving assembly 1 is provided with a limiting groove. The first processing part of the processing assembly 3 is embedded in the limiting groove. The driving assembly 1 drives the processing assembly 3 to move along the vertical direction through the limiting groove during rotation. The limiting plate 41 is arranged on the side of the supporting base 2 away from the driving assembly 1 and above the processing assembly 3.

[0034] Referring to Figure 4 The abutting block 46 is arranged on one side of the limiting plate 41 and forms a first discharging groove 421 and a feeding area with the limiting plate 41. The sliding sheet 451 is embedded in the limiting plate 41. The abutting block 46 is fixedly connected with the sliding sheet 451. The end of the sliding sheet 451 away from the limiting plate 41 is fixedly connected with the first connecting rod 452. The first connecting rod 452 is connected with the second connecting rod 453 on the side away from the driving assembly 1. The side of the supporting base 2 close to the driving assembly 1 is provided with a limiting recess 458. The first rotating shaft 455 is embedded in the limiting recess 458. The end of the second connecting rod 453 away from the driving assembly 1 and the end of the third connecting rod 454 close to the driving assembly 1 are connected through the first rotating shaft 455. The end of the third connecting rod 454 close to the limiting plate 41 is connected with the first pushing rod 456. The end of the first pushing rod 456 away from the third connecting rod 454 is connected with the first pushing plate 457. The first feeding plate 42 is fixedly connected with the end of the third connecting rod 454 close to the supporting base 2. The end of the first feeding plate 42 close to the supporting base 2 is fixedly connected with one end of the connecting column 43.

[0035] The end of the connecting column 43 away from the first feeding plate 42 is fixedly connected with the second feeding plate 44. The second feeding plate 44 is fixedly connected with the first pushing assembly 45. Referring to Figure 4, the second upper feeding plate 44 and the limiting plate 41 form a second lower feeding groove 441. The driving assembly 1 is controlled to move upward during rotation, and the processing assembly 3 moves upward during the movement, pushing the abutting block 46 to move upward, so as to push the first pushing assembly 45 connected with the abutting block 46 to push the pipe to be processed on the second upper feeding plate 44.

[0036] The implementation principle of the embodiment 1 is that, during processing, the driving assembly 1 is started to drive the processing assembly 3 fixedly connected therewith to rotate. Since the first processing part of the processing assembly 3 is embedded in the limiting groove of the support base 2, the processing assembly 3 moves along the vertical direction defined by the limiting groove under the driving of the driving assembly 1. When the driving assembly 1 rotates to move the processing assembly 3 upward, the abutting block 46 is pushed to move upward, and the first pushing assembly 45 connected with the abutting block 46 is subjected to the upward force of the abutting block 46 and moves in the limiting groove 458, so as to push the pipe to be processed on the second upper feeding plate 44 to orderly enter the second lower feeding groove 441. Embodiment 2

[0037] Referring to Figure 5 and Figure 6 The control device of the vehicle rearview mirror rod thread rolling machine further includes a second pushing assembly 5, a lifting assembly 6, a lower feeding container 7, and a recovery container 8. The second pushing assembly 5 includes a second pushing rod 51 and a second pushing plate 52. The second pushing rod 51 is fixedly connected with the first pushing assembly 45. One end of the second pushing plate 52 is fixedly connected with the end of the second pushing rod 51 away from the first pushing assembly 45. The second pushing assembly 5 moves with the movement of the first pushing assembly 45. When the first rotating shaft 455 of the first moving assembly moves in the limiting groove 458, the second pushing plate 52 moves along the side of the first upper feeding plate 42 away from the support base 2 and pushes the pipe to be processed on the first upper feeding plate 42.

[0038] The lifting assembly 6 includes a sliding plate 61, a lifting bracket 62, and a lifting clamp 63. The sliding plate 61 is fixedly connected with the side of the limiting plate 41 close to the first upper feeding plate 42 and is located above the first upper feeding plate 42. The sliding plate 61 is provided with a sliding groove. The lifting bracket 62 is telescopic, one end of the lifting bracket 62 is embedded in the sliding groove and moves horizontally through the sliding groove. The other end of the lifting bracket 62 is fixedly connected with the lifting clamp 63. The lifting clamp 63 is attached with red dye for marking the pipe to be processed that has been lifted.

[0039] The lower feeding container 7 is fixed to the end of the support base 2 close to the processing assembly 3 and is located directly below the first lower feeding groove 421 to receive the pipe to be processed processed from the feeding area. The recovery container 8 is fixed to the end of the support base 2 close to the processing assembly 3 and is located next to the lower feeding container 7 to receive the unqualified pipe to be processed.

[0040] The implementation principle of the embodiment 2 is that when the driving assembly 1 drives the machining assembly 3 to rotate and move upward, the machining pipe on the second feeding plate 44 is pushed by the abutting block 46 and the first pushing assembly 45, and the second pushing assembly 5 fixedly connected with the first pushing assembly 45 is also moved and pushes the machining pipe on the first feeding plate 42, so that the machining pipe on the first feeding plate 42 falls into the first discharging groove 421. When the machining speed of the pipe is 0, the lifting assembly 6 is controlled to perform lifting operation, the lifting clamping jaw 63 clamps the machining pipe in the first discharging groove 421, and the lifting bracket 62 lifts the machining pipe, so that the machining pipe returns to the feeding area from the first discharging groove 421. The red dye attached to the lifting clamping jaw 63 leaves a mark on the machining pipe. After one lifting operation, the lifting bracket 62 moves horizontally along the sliding groove to change the marking position of the machining pipe for the next time, so as to judge the lifting times. When an abnormal machining pipe is found, the second pushing assembly 5 can be controlled to make the abnormal machining pipe fall into the recycling container 8.

[0041] Based on the same inventive concept, the embodiment of the present application provides a vehicle rearview mirror rod rolling thread machine control method.

[0042] With reference to Figure 7 A vehicle rearview mirror rod rolling thread machine control method comprises the following steps. Step S1: acquiring a discharging area video.

[0043] The discharging area video refers to video information collected in real time by a camera arranged in the discharging area of the rolling thread machine. The video can comprehensively reflect the flow state of the pipe in the discharging area.

[0044] Step S2: analyzing the discharging area video to obtain a pipe machining speed.

[0045] The pipe machining speed refers to the machining speed of the pipe. Specifically, the pipe falling frequency is obtained by calculating the number of pipes falling in the video and the time of pipe falling, and the pipe machining speed is obtained by converting the pipe falling frequency. The discharging area is the area of the discharging container 7 carrying the machining pipe falling. Specifically, the number of pipes in the discharging container 7 is obtained according to the total weight of the pipes in the discharging container 7 and the weight of a single pipe, and then the number of pipes in the discharging container 7 per unit time, that is, the pipe falling frequency, is obtained.

[0046] Step S3: when the pipe machining speed is 0, obtaining the weight of the machining pipe in the feeding area.

[0047] The weight of the pipe to be processed refers to the weight of the pipe to be processed in the feeding area, which is obtained by the weight sensor built in the first feeding plate 42.

[0048] Step S4: When the weight of the pipe to be processed is not 0, determine the blocking state of the feeding area, and control the second pushing assembly 5 to execute the pushing operation based on the preset blocking pushing scheme until the pipe processing speed is not equal to 0.

[0049] The blocking state of the feeding area refers to a state in which the blocking of the pipe to be processed in the feeding area is determined.

[0050] When the weight of the pipe to be processed is not 0, it indicates that there is a pipe to be processed in the feeding area, and in combination with the pipe processing speed being 0, it can be judged that the pipe to be processed in the feeding area is blocked, so the blocking state of the feeding area is determined. The blocking pushing scheme refers to a pushing strategy for solving the blocking problem of the feeding area. The scheme specifies specific parameters of the second pushing assembly 5 when executing the pushing operation, such as pushing strength, pushing direction, and single pushing duration, etc. The blocking pushing scheme is set by human beforehand.

[0051] Further comprising: Step S5: Cumulative number of continuous pushing operations after the pushing operation is completed.

[0052] The number of continuous pushing operations refers to the cumulative value of the number of continuous pushing operations, specifically, after the second pushing assembly 5 executes the pushing operation in the blocking pushing scheme each time, the number of this pushing operation is cumulatively counted, and this pushing operation is included in the statistics of the number of continuous pushing operations.

[0053] Step S6: When the number of continuous pushing operations is greater than the preset maximum pushing operation number threshold, execute the lifting operation. The lifting operation is to control the pipe to be processed in the feeding area of the lifting assembly 6 to lift along the length direction of the lifting support 62, so as to control the pipe to be processed in the first discharge groove 421 to fall into the feeding area.

[0054] The maximum pushing operation number threshold refers to a value that limits the number of pushing operations, specifically, the upper limit value of the number of continuous pushing operations, which is set by human beforehand. When the number of continuous pushing operations exceeds the maximum pushing operation number threshold, it indicates that the current blocking problem cannot be effectively solved by the conventional pushing operation. At this time, the system triggers the lifting operation. The lifting operation is executed by the lifting assembly 6, so that the pipe originally blocked in the first discharge groove 421 can fall into the feeding area again, thereby breaking the blocking state and restoring the normal flow of the pipe.

[0055] Step S7: When the pipe processing speed is still 0 after executing the lifting operation, repeat the lifting operation and cumulatively count the number of lifting operations until the pipe processing speed is not 0.

[0056] The lifting number refers to the number obtained by counting the cumulative number of lifting operations performed on the lifting assembly 6, and is not a continuous lifting number. Specifically, each time the lifting assembly 6 is lifted along the length direction of the lifting support 62 after processing the pipe, the system counts this lifting and includes this lifting operation in the statistics of the lifting number. When the pipe processing speed is still 0 after performing the lifting operation, it indicates that the current blockage problem may be caused by the same size of the pipe to be processed. At this time, the system triggers the lifting operation again and continues to count the lifting number. This process will continue until the pipe processing speed returns to a state where it is not 0, maintaining the processing operation of the pipe to be processed without being interrupted for a long time, and the pipe can be normally processed and flowed.

[0057] Step S8: When the lifting number is greater than the preset maximum lifting operation number threshold, output a preset device abnormal signal.

[0058] The maximum lifting number threshold refers to a preset value used to define the upper limit of the lifting operation number. This threshold is set by humans in advance, aiming to prevent excessive wear and tear of the equipment or other uncontrollable problems caused by unlimited lifting operations. The device abnormal signal refers to a signal used to prompt the current abnormal condition of the equipment. This signal is presented through sound and light alarm, so that the operator can timely obtain the equipment abnormal information and take corresponding inspection and maintenance measures. When the system detects that the lifting number exceeds the preset maximum lifting operation number threshold, it indicates that the current feeding area blockage problem is not caused by the pipe to be processed, and the equipment may have failed, so the output of the device abnormal signal is triggered immediately.

[0059] Further comprising: Step S9: When the pushing operation is performed, the pushing speed is obtained.

[0060] The pushing speed refers to the rate at which the pipe is pushed during the execution of the pushing operation by the second pushing assembly 5. Specifically, the pushing speed can be obtained in real time by installing a speed sensor on the second pushing assembly 5. The sensor can accurately measure the movement distance of the pushing plate or pushing rod in a unit of time, thereby obtaining the specific value of the pushing speed.

[0061] Step S10: When the pushing speed of the second pushing assembly 5 is 0 within the preset single pushing time, control the second pushing assembly 5 to perform a preset correction pushing operation until the pipe processing speed is not 0.

[0062] The single pushing duration refers to the maximum time length allowed for the second pushing assembly 5 to perform a single pushing operation, which is artificially preset to ensure that the pushing operation can be completed within a reasonable time and avoid affecting the overall processing efficiency due to excessively long pushing time. The correction pushing operation refers to a pushing operation with a higher pushing frequency, specifically referring to a pushing operation with more times per unit time to achieve a shaking state of the pipe to be processed in the feeding area, aiming to eliminate the blocking situation of the pipe to be processed in the feeding area.

[0063] When the pushing speed of the second pushing assembly 5 is detected as 0 within the single pushing duration, it indicates that the current pushing operation fails to effectively push the pipe, and the pipe to be processed in the feeding area may have a problem with the placement position, resulting in a more serious blocking situation. Therefore, the pushing operation has a problem of insufficient pushing force and too slow pushing frequency. At this time, the system will immediately control the second pushing assembly 5 to perform a correction pushing operation, Step S11: Accumulate the correction pushing operation duration when performing the correction pushing operation.

[0064] The correction operation duration refers to the time length experienced from the start to the end of the correction pushing operation. Specifically, the system starts a timer to accurately record the duration of the operation when starting the correction pushing operation. The timer continuously accumulates time when the correction pushing operation is performed until the operation is completed.

[0065] Step S12: Output a preset alarm signal when the correction pushing operation duration is greater than the preset single correction pushing duration.

[0066] The single correction pushing duration refers to the maximum time limit for the correction pushing operation to continue. This duration is determined through multiple experiments of correction pushing operation when there is a blocking situation in the feeding area. The alarm signal refers to a warning information for prompting the timeout of the correction pushing operation, which is presented through sound and light alarm. The light color presented by the alarm signal is different from the light color presented by the equipment abnormal signal, which is convenient for the staff to identify. When the correction pushing operation duration exceeds the preset single correction pushing duration, it indicates that the current correction pushing operation fails to effectively solve the blocking problem in the feeding area, and continuing to perform the correction pushing operation cannot produce effect, so the alarm signal is output.

[0067] The method further includes a method for determining the lifting times, which includes: Step S13: Obtain the mark image when performing the lifting operation.

[0068] The marking image refers to an image obtained by an image acquisition device arranged near the lifting clamp 63 during the lifting operation, which contains the image of the red dye marking on the pipe to be processed on the lifting clamp 63. Specifically, the image acquisition device will take a picture of the pipe at the moment when the lifting operation is completed, and these images will be transmitted to the image processing module of the control system. The image processing module will preprocess the received marking image, including denoising, contrast enhancement and other operations.

[0069] Step S14: Analyze the marking image to determine the number of marked pipes.

[0070] Referring to Figure 8 Each time the lifting clamp 63 lifts the pipe to be processed, it will attach a mark to the surface of the pipe to be processed, and the mark position will change with the number of lifts. The number of marked pipes refers to the number of pipes to be processed that are marked with red dye in the marking image. Specifically, the image processing module will use image recognition algorithms to analyze the preprocessed marking image in depth. Here, an edge detection algorithm is used to accurately count the number of marked pipes by using the color characteristics of the red dye and the shape characteristics of the pipe, thereby determining the number of marked pipes.

[0071] Step S15: Define the number of marked pipes as the number of lifts.

[0072] When only one abnormal workpiece is present, the blocking operation after each lift is caused by the abnormal workpiece falling into the first discharge chute 421. Since the frequency of the abnormal workpiece falling into the first discharge chute 421 is low, when the abnormal workpiece causes the pipe processing speed to be 0, the lifting operation is continued, but the number of lifts is not accumulated. The number of lifts is equal to the number of abnormal pipes. When the number of abnormal pipes is too large, it is easy to cause the first discharge chute 421 to be blocked by the abnormal pipe soon after the lifting operation is performed. Therefore, in the subsequent process, special treatment will be performed when the number of lifts is too large. If there is a second abnormal workpiece, the number of lifts is twice the number of lifts. The number of lifts can confirm the number of abnormal pipes in the current feeding area. Here, if the number of abnormal pipes is too large, it indicates that the cause of the blockage is not the size of the pipe. It may also be a problem with the equipment.

[0073] The method also includes a pipe processing optimization method for the feeding area when the number of marked pipes is present, which includes the following steps: Step S16: Based on the analysis of the marking image, the number of marks attached to a single pipe to be processed is obtained, and is defined as the number of abnormal marks.

[0074] The abnormal marking quantity refers to the number of markings on a single pipe to be processed in the marking image. Specifically, after the image processing module identifies the marked pipe, it further analyzes the number of markings on each pipe. Since the lifting clamp 63 will slide horizontally to change the clamping position after each lifting operation, different red marks will be left on the pipe at different positions when there are different lifting times. Therefore, by counting the number of markings on the pipe, it can be determined how many times the pipe has caused blockage in the feeding area. Here, it is to avoid the problem of non-abnormal pipe placement causing the first discharge slot 421 to be blocked, so the pipe that has been lifted is marked.

[0075] Step S17: When the abnormal marking quantity is greater than the preset maximum abnormal marking quantity, determine the abnormal pipe.

[0076] The maximum abnormal marking quantity refers to a preset value for defining the upper limit of the number of markings on the pipe to be processed. This value is determined based on the length of the pipe, which affects the number of times the pipe can be marked at different positions. The abnormal pipe refers to the pipe that causes blockage in the feeding area. The abnormal pipe may be due to surface impurities or size exceeding other pipes, causing it to be unable to pass through the first discharge slot 421 into the processing link. When the system detects that the abnormal marking quantity on a pipe to be processed exceeds the preset maximum abnormal marking quantity, it determines that the pipe is an abnormal pipe. Here, the maximum abnormal marking quantity is four times. When a pipe has four different position markings on its surface, the image of the pipe surface can determine how many times the pipe has been lifted. If the current lifting time is six times, there are four different position markings on the pipe, which correspond to the first, second, fourth and sixth lifting times. Therefore, the current lifting time can be determined by the image of the pipe surface. When there are four different position markings on the pipe, it means that the pipe has caused four times of blockage in the feeding area and exceeds the maximum abnormal marking quantity, so the pipe is determined to be an abnormal pipe.

[0077] Step S18: Obtain the image of the feeding area and determine the position of the abnormal pipe based on the image of the feeding area.

[0078] The abnormal pipe position refers to the specific location of the abnormal pipe in the loading area. Specifically, the real-time image of the loading area is obtained through the camera or other image acquisition device arranged above the loading area, and then the image recognition technology is used to accurately locate the position of the abnormal pipe in the loading area image, and the position of the abnormal pipe is converted into coordinate form and sent to the system, which facilitates the subsequent operation of the system. The image algorithm here is YOLO algorithm, which divides the image into grids and directly predicts the bounding box (x, y, w, h) of the abnormal pipe in each grid through a deep learning model, where (x, y) is the center coordinate of the bounding box, and combined with the preset coordinate system of the loading area (here, a two-dimensional coordinate system is established with the camera as the origin), the bounding box coordinate can be converted into the position of the abnormal pipe in the physical space.

[0079] Step S19: When the abnormal pipe position falls into the preset unloading area, an abnormal pipe pushing scheme is formed based on the abnormal pipe position, and the second pushing assembly 5 is controlled to push the abnormal pipe according to the abnormal pipe pushing scheme until there is no abnormal pipe in the loading area.

[0080] The unloading area refers to a specific local area in the loading area adjacent to the first unloading groove 421. The abnormal pipe pushing scheme refers to a special pushing strategy formulated for the abnormal pipe. This scheme specifies various parameters of the second pushing assembly 5 in pushing the abnormal pipe in combination with the abnormal pipe position, including pushing strength, pushing direction, pushing speed, and single pushing duration. Specifically, after the system determines the abnormal pipe position through the loading area image, it further judges whether the position falls into the preset unloading area. If it falls into, an abnormal pipe pushing scheme is generated to make the abnormal pipe away from the unloading area. Here, it is not possible to completely isolate all abnormal pipes from entering the first unloading groove 421, so the lifting operation will still be triggered.

[0081] The method further includes a method for recycling abnormal pipes, which comprises: Step S20: Determine the recycling position according to the loading area image.

[0082] The recovery position refers to a position specially set in the feeding area for recovering abnormal pipe fittings. Specifically, it refers to the highest point of the pipe fittings to be processed accumulated in the feeding area. Because the second pushing assembly 5 recovers the highest point of the pipe fittings to be processed accumulated in the feeding area, it does not affect other pipe fittings to be processed. Therefore, this position is used as the recovery position. By analyzing the image of the feeding area, the accumulation of pipe fittings to be processed is observed in real time, and the recovery position is updated in real time. It should be noted that because the speed at which the pipe fittings to be processed fall into the first discharge groove 421 is relatively fast, the second pushing assembly 5 cannot perform recovery operations on the recovery position that is updated too quickly in this case. Therefore, the second pushing assembly 5 generally performs recovery operations only when the feeding area is blocked.

[0083] Step S21: When the abnormal pipe fitting position falls into the recovery position, determine the pipe fitting to be recovered.

[0084] The pipe fitting to be recovered refers to abnormal pipe fittings whose positions are within the recovery area. Specifically, after the system determines the position of the abnormal pipe fitting through image recognition technology, it further determines whether the position coincides with the recovery position or falls within the recovery area. If the condition is met, the abnormal pipe fitting is marked as a pipe fitting to be recovered.

[0085] Step S22: When there is a pipe fitting to be recovered and there is no equipment abnormal signal, control the second pushing assembly 5 to perform recovery operations based on the recovery position and the preset recovery scheme. The recovery operation is to lift the pipe fitting to be recovered by the second pushing assembly 5, and make the pipe fitting to be recovered leave the feeding area.

[0086] The recovery scheme refers to a detailed recovery strategy developed for the pipe fitting to be recovered. The accurate coordinates of the pipe fitting to be recovered in the recovery position are determined, and then the path of the second pushing assembly 5 from the current position to the recovery container 8 is planned in combination with the preset coordinate system of the feeding area and the recovery container 8. During the movement, the second pushing assembly 5 will accurately lift the pipe fitting to be recovered according to the preset pushing force and pushing direction, and ensure that it does not interfere with other pipe fittings to be processed during the lifting process. It should be noted that the second pushing plate 52 is provided with a hooking structure for hooking the pipe fittings to be processed. This structure can adjust the shape of the hooking structure in real time when pushing and recovering the pipe fittings to be processed, ensuring that the hooking structure is in a retracted state during the pushing process, and the hooking structure can be expanded and accurately hook the pipe fitting to be recovered during the recovery process. The hooking structure is not shown in the figure. After the pipe fitting to be recovered is lifted, the second pushing assembly 5 will move the pipe fitting to be recovered out of the feeding area smoothly according to the preset movement trajectory, until it reaches the designated recovery container 8.

[0087] When the lifting frequency is greater than the maximum lifting operation frequency threshold, the method for outputting the equipment abnormal signal comprises: Step S23: When the number of lifting operations is greater than the maximum number of lifting operation threshold, determine that the foreign matter is blocked.

[0088] The maximum number of lifting operation threshold refers to the preset value mentioned above for defining the upper limit of the number of lifting operations, which will not be repeated here. The foreign matter blockage refers to a blockage in the feeding area caused by non-processed pipe factors. Specifically, when the system detects that the number of lifting operations exceeds the maximum number of lifting operation threshold, the system determines that there may be non-normal pipe blockage factors in the feeding area, i.e. foreign matter blockage, or there are a large number of abnormal pipes in the feeding area, indicating that at this time, there may be foreign matter mixed into the first discharge chute 421 that does not belong to the category of pipes to be processed, causing the pipes to be processed to be unable to fall into the processing link from the first discharge chute 421 or the equipment to be unable to enter the processing area.

[0089] Step S24: Based on the foreign matter blockage, find the preset foreign matter pushing scheme, and control the lifting assembly 6 to perform the lifting operation based on the foreign matter pushing scheme.

[0090] The foreign matter pushing scheme refers to a special solution developed for the foreign matter blockage situation, which specifies various parameters of the lifting assembly 6 when performing the lifting operation, including lifting force, lifting direction, and lifting speed, etc. The lifting operation refers to the operation of the lifting assembly 6 to lift the foreign matter, which is performed by the lifting assembly 6 according to the parameter settings in the foreign matter pushing scheme to scrape up and down the foreign matter that may exist in the first discharge chute 421. Specifically, the lifting assembly 6 will start operating according to the preset lifting force, in the vertical upward lifting direction and lifting speed.

[0091] Step S25: After the lifting assembly 6 performs the lifting operation, if the pipe processing speed is still 0, output the equipment abnormal signal.

[0092] When the lifting assembly 6 performs the lifting operation, and the pipe processing speed is still 0, it indicates that the lifting operation has not effectively solved the blockage problem of the feeding area, and there may be the following situations: one is that the foreign matter blockage is too serious and the lifting operation cannot remove it; two is that the foreign matter is not located near the first discharge chute 421 and the lifting operation cannot reach it; three is that there is other fault in the equipment, causing the pipe processing speed to still not recover even if the foreign matter is removed. In these situations, the system determines that the current equipment state is abnormal and cannot continue normal pipe processing, so it will immediately output the equipment abnormal signal to prompt the staff to repair and handle, so as to ensure that the equipment can resume normal operation as soon as possible.

[0093] The method also includes a method for cleaning the feeding area, which includes: S26: Obtain the image of the feeding area, and analyze based on the image of the feeding area to obtain the characteristics of the feeding area.

[0094] The loading area feature refers to the performance characteristics of the loading area in the image, including the distribution state of the pipe fittings, the stacking height, and whether there are foreign matters, etc. Specifically, the system will obtain real-time images through the camera or other image acquisition devices arranged above the loading area, and then identify the outline of the pipe fittings through edge detection algorithm to determine whether there are pipe fittings in the loading area.

[0095] S27: Determine the idle state of the loading area according to the loading area feature.

[0096] The idle state of the loading area refers to a state in which there are no pipe fittings to be processed in the loading area, which is not sufficient to trigger any processing or pushing operation.

[0097] S28: When the idle state of the loading area exists, control the second pushing assembly 5 to perform the cleaning pushing operation based on the preset cleaning pushing scheme.

[0098] The cleaning pushing scheme refers to a scheme for controlling the second pushing assembly 5 to clean the loading area, specifically a pushing strategy designed for the idle state of the loading area, which is used to clean small foreign matters or residues that may be left in the loading area. The cleaning pushing operation refers to the pushing operation of the second pushing assembly 5 according to the cleaning pushing scheme. The cleaning pushing scheme specifies various parameters of the second pushing assembly 5 when performing the cleaning pushing operation, including the pushing direction, the pushing speed, and the duration of a single pushing, etc. When the loading area is in the idle state, it means that there are no pipe fittings to be processed in the loading area at this time, so the second pushing assembly 5 is controlled to perform the cleaning pushing operation.

[0099] S29: Real-time obtain the pushing speed of the second pushing assembly 5 during the execution of the cleaning pushing operation of the second pushing assembly 5, and define it as the cleaning speed.

[0100] The cleaning speed refers to the moving speed of the second pushing assembly 5 when performing the cleaning pushing operation, which is obtained by observing the pushing frequency of the second pushing assembly 5 within a certain period of time through the camera.

[0101] S30: When the cleaning speed is 0, pause the cleaning pushing operation and output a preset manual cleaning signal.

[0102] The manual cleaning signal refers to a signal prompting the staff to manually clean the loading area. When the system detects that the cleaning speed is 0, it means that the second pushing assembly 5 may have encountered obstacles or foreign matters that cannot be automatically handled, at this time, the system will automatically pause the cleaning pushing operation and trigger the manual cleaning signal. The signal is conveyed to the staff through the indicator light on the control panel, reminding them to intervene.

Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
