Description

Technical Field

[0001] The present invention relates to the technical field of line process control, and in particular to a method and system for line equipment process flow control. Background Art

[0002] At present, in the production process of magnetic steel components, due to the different characteristics of the glue used, the specific glue application temperature and process time are not accurately controlled, which will lead to unstable component product yield. At the same time, the "extensive" process of glue in the entire control link will cause difficulty and confusion in the control of a series of links such as glue reception, glue splitting, glue distribution, glue use, and glue recycling. The unclear glue use process will cause inefficiency in normal component production activities and reduce the yield of component production.

[0003] In addition, in the production process of magnetic steel components, due to employee interference, the jigs are interchanged on the transmission line during the production process, and the processes are reduced, increased, or skipped. Or the middle and rear equipment of the line are abnormally unable to work while the front equipment continues to produce, causing the product defect rate to rise sharply. It will also cause the normal component production activities to be inefficient. The efficiency, yield, defect rate ratio, equipment status, line achievement rate and other data of each equipment in the line are unclear, causing on-site managers to be unsure of the accuracy of the data, resulting in erroneous data reporting that affects the production progress of the entire project.

The first fixture return conveying line 54 is installed at the position where the fixture return conveying module 55 is in place.

[0047] The method for using the above-mentioned line equipment system includes the following steps:

[0048] Step 1: Manually put the jig into the dispensing transmission line 11, the first code scanning mechanism 7 scans the QR code on the jig and transmits it to the server. After the code is scanned, the dispensing jig positioning mechanism 6 positions the jig, and the dispensing machine 8 dispenses glue on the jig and starts timing. After the dispensing is completed, the dispensing positioning mechanism 6 cancels the positioning, and the jig flows through the dispensing transmission line 11 through the CCD detection mechanism 9. The detection and positioning mechanism locates and takes pictures to scan the dispensing status. After the photo analysis is completed, the corresponding data is uploaded and the detection and positioning is canceled, and the jig continues to flow to the next process;

[0049] Step 2: The fixture enters the range of the second code scanning mechanism 17 again through the dispensing transmission line. The code scanning mechanism reads the QR code data of the fixture and transmits the data to the server for judgment. According to the judgment of the system, the components in the fixture are assembled or flowed away directly without assembly. If the code scanning data is OK, the vibration plate 22 and the direct vibration 24 vibrate to feed the material through the material channel 23. The staggered cylinder 25 is used to stagger the feeding so that the feeding becomes 1 out of 6. The assembly positioning mechanism positions the jacking fixture, and the assembly handling module 27 moves to the material picking position. The handling lifting cylinder 29 descends to absorb the material. After completion, it rises and moves to the discharge position. The handling lifting cylinder 29 and the handling demoulding cylinder 28 descend at the same time. After reaching the position, the handling lifting cylinder 29 rises back to its original position to complete the assembly.

[0050] Step 3: The assembled fixture is transported to the end through the assembly transmission line 16. The pre-hot pressing transport mechanism 30 transports the fixture to the discharge position. At the same time, the fourth barcode scanning mechanism 34 scans the QR code on the fixture. According to the data previously collected by the system, it is analyzed whether the hot pressing process is required or the material is directly thrown. If the data of the fourth barcode scanning mechanism 34 is OK, that is, the time difference between the dispensing start time T1 and the pre-hot pressing detection time (T2) is ≤60S, the hot pressing process is carried out. Otherwise, the material is directly thrown. When the CT difference is ≤60S, the pre-hot pressing transport mechanism 30 places the fixture on the left loading tray of the XY transport mechanism 31. The XY transport mechanism moves to any hot pressing mechanism that has completed the hot pressing process and is in an idle state. After the hot pressing is completed, the right material picking tray of the right XY transport mechanism sucks the fixture and moves it to the post-hot pressing transport module and places it on the laser engraving transmission line 45.

[0051] Step 4: The jig flows into the automatic laser engraving equipment 4, and the laser engraving positioning mechanism positions the laser engraving. After the laser engraving is completed, the jig is scanned by the laser engraving transmission line 45 to the fifth scanning mechanism 47, merged with the data in the database, and uploaded to the server. If the first four processes are normally circulated, it will pass through the glue cleaning conveyor line 48 and enter the glue cleaning link.

[0052] Step 5: The jig flows into the cleaning glue conveying line 48 through the laser engraving transmission line 45 and enters the automatic cleaning glue link. The sixth scanning mechanism 49 scans the jig. The jig must go through the laser engraving process and each of the previous processes. If the jig goes directly to the cleaning glue process without going through the laser engraving process, the cleaning glue equipment will not grab the jig for cleaning glue, and the conveying mechanism will perform a reflux action, and the product will not leak the laser engraving phenomenon; if the jig goes directly to the cleaning glue process after the laser engraving process and reaches the end of the cleaning glue conveying line 48, the cleaning glue positioning mechanism positions the jig, and the cleaning glue conveying mechanism 53 conveys the assembly to the rotating cleaning glue mechanism 51. On the rotating base 56, the rotating motor 58 rotates 180° to the bottom of the galvanometer of the glue cleaning machine 50 to realize automatic rotating glue cleaning. After the glue cleaning is completed, the rotating motor 58 rotates 180° again to the unloading position, the rotating material picking mechanism 52 removes the glue cleaning completion component, the rotating unloading cylinder 63 rotates to the finished material box, the polyurethane clamping cylinder 54 is released, and the material falls into the finished product box. At the same time, the jig flows to the end of the glue cleaning conveying line 48, and is transported to the first jig reflux conveying line by the jig reflux conveying module, passes through the first jig reflux conveying line to the fifth jig reflux conveying line, and returns to the starting position.

[0053] The method for controlling the process flow of the line equipment system is specifically as follows: according to the characteristics of the glue used and the characteristics of the line process control, a communication command is sent through a code scanning mechanism. After receiving the command, the server first analyzes the QR code data and then transmits different identification information to the corresponding equipment. After the equipment starts the process action, the code scanning mechanism reader reads the QR code information of the fixture from the QR code label on the fixture for identification. The information data is transmitted to the PLC numerical control module through the serial port protocol data communication. The PLC numerical control module edits and processes multiple groups of information data. Since the industrial computer and the human-machine interface are also electrically connected to the PLC numerical control module through the communication module (OPC Ethernet communication), the industrial computer will collect and display the information data, and analyze the corresponding process time, process interval time, glue temperature in the dispensing process, hot pressing temperature and holding time, and equipment process sequence according to the QR code process flow characteristic information. If the normal use temperature of the glue is exceeded, the process time is exceeded, and the corresponding work flow is missing, it is judged to be NG, and an alarm will be sent back to the PLC numerical control module of the corresponding equipment. The equipment is adjusted manually according to the NG information displayed on the human-machine interface of the corresponding equipment.

[0054] In summary, the present invention utilizes a code scanning mechanism to scan, upload, analyze, record, feedback, and implement the QR code before and after each process, so as to realize glue control, laser engraving control, equipment status control, data collection, and fixture control. Glue control can be used to reduce the defective rate of the process; laser engraving control can be used to prevent laser engraving from being missed; equipment status control can be used to control the status of each device; data collection can be used to collect information on the data and status of each device, which is beneficial for abnormal problem analysis; fixture control can be used to control the service life of the fixture by inspecting the fixture, tracing fixture maintenance, and maintaining the fixture. The overall assembly line of the equipment operates automatically, and automatic process flow control can be realized through scanning and collecting data feedback of each process, thereby reducing the defective rate of the process, reducing human resource costs, and conveniently and quickly maintaining the equipment of each process.
