Description

Technical Field

[0001] This invention relates to the field of testing technology for key components of cigarette rolling and packaging machines, specifically to a comprehensive quality inspection operation platform and system for key assemblies of rolling and packaging equipment. Background Technology

[0002] With the development of the social economy and the continuous increase in the number of smokers in my country, the labor productivity of tobacco production enterprises has gradually increased, and the equipment used has also become more advanced. However, the traditional regular maintenance management model is no longer suitable for the maintenance and management of modern tobacco production equipment, because a lack of understanding of the equipment's operating status may lead to equipment neglect or over-maintenance, negatively impacting the enterprise's economic benefits.

[0003] In the tobacco industry, due to the complexity of packaging equipment and the wear and tear caused by long-term operation, equipment failures and downtime have become one of the bottlenecks restricting the development of the tobacco industry. Currently, the management of tobacco packaging equipment mainly relies on manual periodic inspection and maintenance, which presents the following problems and challenges.

[0004] 1.1 Inability to monitor equipment operating status in real time: Traditional periodic maintenance methods can only perform routine checks on equipment at fixed time intervals, and cannot monitor the operating status and working conditions of the equipment in real time. Due to the long operating time and varying degrees of wear and tear, equipment may malfunction during operation, and problems may not be detected and resolved in a timely manner, resulting in downtime and production interruptions.

[0005] 1.2 Lack of accurate judgment and analysis of equipment maintenance: Due to a lack of understanding of the equipment's operating status, enterprises find it difficult to accurately determine whether equipment needs to be shut down for maintenance or parts replacement. Sometimes this leads to over-maintenance, resulting in wasted resources; other times it results in equipment neglect or shutdown, negatively impacting production and the enterprise's economic benefits.

[0006] 1.3 High Cost of Manual Maintenance: Traditional periodic maintenance and repair models require a large amount of manpower and resources, which not only increases the company's costs but also fails to guarantee the reliability and stability of the equipment. Tobacco packaging equipment usually operates continuously and cannot be shut down for extended periods for maintenance. This necessitates a large number of maintenance engineers and technicians to inspect and maintain the equipment, increasing the complexity and cost of management.

[0007] 1.4 Lack of Equipment Failure Early Warning Mechanism: The current management model for tobacco packaging equipment cannot detect equipment failures in advance and lacks an early warning mechanism. It relies solely on manual inspections and post-failure repairs, failing to prevent and address equipment failures promptly. Equipment failures are often sudden and unpredictable; without a warning mechanism, they could lead to severe shutdowns and production interruptions, potentially causing the failure to escalate and further impacting production and economic efficiency.

[0008] In cigarette making and packaging machines, assemblies are crucial components. Dynamic testing of the ten most important assemblies in these two types of machines includes the first separating drum assembly, receiving drum assembly, cutter head assembly, cutting disc assembly, tipping paper cutter assembly, small package oil seal conveyor and cutter assembly, small oil container, cigarette belt assembly, inner frame paper cutter assembly, and large glue cylinder assembly. These assemblies play a vital role in the operation of the entire machine and product quality. Regular maintenance and quality inspections are necessary to ensure their good and lasting performance. Each assembly requires maintenance to ensure it remains in optimal condition, thereby guaranteeing stable operation and efficient production of the entire machine.

[0009] However, most testing equipment on the market today is standalone, only capable of testing a single assembly. It is complex to operate, lacks versatility, and leads to inconvenient management, operation, low efficiency, and wasted time and effort. Most current testing equipment can only perform static testing, unable to accurately simulate the operating state of assemblies under different conditions, thus failing to accurately assess their performance and quality. Furthermore, these devices often lack effective data management and statistical functions, failing to provide users with complete assembly usage and maintenance records, and lacking management of the entire assembly lifecycle, which significantly impacts efficiency and quality. A complete supervisory control software solution can help solve this problem, as it can provide dynamic testing, information management, and maintenance record functions, greatly improving equipment utilization efficiency and maintenance quality. Summary of the Invention

[0010] To address the shortcomings and deficiencies of existing technologies and resolve practical problems such as inefficient and non-lean assembly management, the inventors' team explored intelligent single-machine and full lifecycle management methods. Focusing on key assemblies in packaging equipment, they employed servo systems, novel sensing technologies, mechanistic analysis, and intelligent algorithms for condition diagnosis. This resulted in the development of a digital intelligent testing and inspection technology-based full lifecycle information management platform for assemblies. This platform enables quantitative evaluation and scientific assessment of post-repair quality inspection of assemblies, as well as condition monitoring of in-use assemblies. Furthermore, it positively impacts maintenance skills and standardization of operations. Ultimately, this prevents excessive wear or damage to assemblies, reduces maintenance time and costs, extends maintenance cycles, and improves the full lifecycle management level of assemblies, including periodic inspections, maintenance adjustments, and post-repair quality inspections. This enhances the leanness, economy, and reliability of equipment management, increases assembly utilization, improves equipment economic operation, and contributes to the overall upgrading of enterprise manufacturing capabilities.

[0011] The working principle of this invention: This invention discloses a comprehensive quality inspection operation platform for key assemblies of packaging equipment. The platform base serves as the main support of the entire testing platform, providing support and load-bearing function. Various supports and testing devices, such as mounting plates for installing motors, spindle units, and connecting flanges, can be integrated on the platform, enabling the key assemblies of the packaging equipment to rotate under motor drive or receive a power source. The lifting platform can be used to install other testing sensors, such as vibration detection sensors and temperature detection sensors. A sensor mounting bracket is also installed on the platform base. This bracket includes horizontal slide rails, vertical slide rails, and transverse rods. The vertical slide rails can slide and be fixed on the horizontal slide rails, and the transverse rods can slide vertically and be fixed on the vertical slide rails. Testing sensors can be installed on the transverse rods, enabling high-altitude installation and fixation of the sensors. The lifting platform can also be used to install other key assemblies of the packaging equipment that are not fixed by a drive shaft, such as the inner frame paper cutter assembly. This system includes components such as large glue cylinder assemblies and small oil beauty container assemblies. Based on different drive components, the alignment of axes is achieved through adjustments to the lifting platform. Combined with the three-axis adjustment of the sensor mounting bracket, it allows for multi-directional placement of sensors to detect the operational parameters of various types of assemblies. The connecting shaft can safely connect up to 10 assemblies from cigarette machines and packaging machines, such as cigarette positioners and paper roll reels. Servo motors drive assemblies to rotate at set speeds, providing power for dynamic quality inspection. Servo controllers control the servo motors, providing different operating conditions for dynamic assembly inspection and thus providing variable conditions for multi-source sensor data acquisition. This simulates the operation of assemblies under different working conditions, improving the accuracy of assembly detection and evaluation. Tooling and fixture modules are used for static inspection of assembly repair quality. Sensor monitoring devices are used for dynamic inspection of assemblies during operation, and also have the functions of sensor data acquisition, storage, and analysis. Laser displacement sensors, vibration detection sensors, and temperature detection sensors are all connected to the main control device. The main control device collects detection data during the detection process and has the functions of processing, displaying, and storing data, facilitating the recording and display of detection results. During the detection process, sensors are used to detect specific positions of key assemblies of the rotating cigarette-making equipment. The spindle unit, through an AC servo motor, can precisely control the angular velocity and angular displacement of the rotating parts of the key assemblies, ensuring that the operation meets the installation and usage accuracy requirements of the cigarette-making equipment cutter assembly. During this process, a runout detection sensor is used to measure the position and displacement of the rotating parts, thereby determining whether the position and displacement of the key parts corresponding to the spindle rotation position and displacement meet the installation and usage accuracy requirements of the cigarette-making equipment assembly. The detection data can be used to determine whether the key assemblies of the cigarette-making equipment are qualified. Another aspect of the present invention provides a host control software system for assembly quality inspection, which has good human-machine operation.The main functions include parameter setting, data storage and statistics, and data fusion analysis. The parameter setting function allows users to input different parameters to control servo motor speed, motion time, and other parameters, enabling dynamic movement of the assembly and simulating different operating conditions. It also collects information such as servo motor torque, phase, and waveform under specific conditions. The data storage and statistics function compares the test data of new and old assemblies to form an assembly test database, facilitating subsequent assembly fault diagnosis research. The data fusion analysis function uses data analysis methods to form quality judgment criteria, determining the repair quality of the assembly through multi-sensor test data, thereby accurately evaluating the repair quality.

[0012] When inspecting the cigarette conveyor belt, another part of the platform base is used. The cigarette conveyor belt assembly integrates a rotating hub and several cigarette mold boxes composed of cigarette frames. The cigarette mold boxes are mounted on the rotating hub, one end of which is a drive turntable, which is fitted onto the output shaft of the cam divider. Driven by the cam divider, the cigarette mold boxes rotate with the belt. The other end of the rotating hub is mounted on the machine frame via a cigarette conveyor belt fixing bracket, allowing the cigarette conveyor belt assembly to be placed horizontally and vertically suspended. When the drive motor starts, it drives the cigarette conveyor belt to rotate intermittently via the cam divider. Four pairs of fiber optic sensors are mounted on their mounting brackets and adjusted to the wall thickness blocking positions at the four corners of each moving cigarette frame in the cigarette conveyor belt assembly. When the cam divider starts rotating, the position of the moving cigarette frame fixture is marked as number 1. Initially, each fixed angle (according to the cigarette conveyor belt assembly's division pitch minus the angle) moves each cigarette frame to a fixed work position. When any of the four pairs of fiber optic sensors is activated, it is determined that the position or shape error of that group of cigarette frame fixtures exceeds the deviation range, and the number of the unqualified cigarette frame fixture is marked according to the counter on the cam divider. This process is repeated for all moving cigarette frame groups to check whether their position and shape errors exceed the deviation range.

[0013] The Assembly Lifecycle Information Platform is an information management module. Centered on assembly operation and maintenance data, it performs assembly lifecycle prediction and demand analysis, and attempts to model and analyze lifecycle predictions, evaluate prediction results, conduct error comparison analysis, and apply case studies. Its main functions include basic data recording, status tracking and effect monitoring, assembly management technology applications, and information platform expansion functions. The basic data recording function allows for the collection and recording of relevant basic data for assemblies, such as details, warehousing, outbound, repair, and return records, repair and replacement lists, and information on the assembly's service life from installation to failure. The status tracking and effect monitoring function utilizes the platform and "one item, one code" technology to track and monitor the maintenance status, installation status, and maintenance effect (responsible person) of packaged assemblies, providing real-time information on the assembly's status. The assembly management technology application function performs assembly lifecycle prediction and demand analysis, and attempts to model and analyze lifecycle predictions, evaluate prediction results, conduct error comparison analysis, and apply case studies. The information platform expansion function allows for the addition of relevant functions based on actual needs.

[0014] The beneficial technical effects of this invention compared to the prior art are as follows:

[0015] (1) Based on the coordinated installation of the platform base, mounting plate, lifting platform, and sensor mounting bracket, the sensor installation is convenient, easy, stable, and reliable. This allows the cutter head assembly to simulate the rotational state during operation. Therefore, the detection results are reliable and stable during the inspection process, and the disassembly and assembly are quick and accurate. The laser displacement sensor can be installed in multiple locations, either above or to the side of the cutter head assembly, facilitating multiple inspections from multiple locations and improving the reliability of the detection results. A qualified cutter head assembly, obtained through inspection, ensures that the angular velocity and angular displacement of the cigarette machine cutter head assembly meet the installation and usage accuracy requirements, thereby guaranteeing the production quality of the cigarette machine and improving production efficiency. Simultaneously, through precise testing and management, the service life of the equipment can be increased, the equipment maintenance cycle extended, and the equipment failure rate and maintenance costs reduced.

[0016] (2) It can detect the conveyor belt assembly of the cigarette mold box in the form of a track. The structure is scientific and reasonable, and the operation is convenient and efficient. It solves the problems of complex structure, cumbersome operation and low production efficiency of the existing test platform. It uses optical sensors as detection devices, which have the characteristics of high sensitivity, non-contact, high efficiency, convenient maintenance and not easy to damage. It is also low cost and compact structure. It uses four pairs of detectors to detect the key position points of the cigarette frame. It can detect the position and shape error of the cigarette frame tooling in a timely, accurate and efficient manner, so as to ensure the quality and production efficiency of the cigarette belt.

[0017] (3) The modular design of the platform base, tools and fixtures, combined with the sensor mounting bracket, lifting platform and assembly belt fixing bracket, enables multiple combination installation and use methods. It can perform installation and testing operations on ten key assemblies, realizing comprehensive, efficient and accurate key parameter testing of assemblies. In addition, with the functions of the control system, parameter setting, data storage statistics and data fusion analysis, it can determine the repair quality of assemblies and improve the assessment capability of assemblies quality. Based on the assembly full life information platform, it can realize management work in four aspects: basic data recording, status tracking and effect monitoring, assembly management technology application and information platform expansion functions, which improves the management efficiency and quality of assemblies.

[0018] (4) The assembly quality inspection upper-level control software is the control system of this platform and should have good human-machine operation. Its functions should include parameter setting, which can control parameters such as the speed and motion time of the servo motor to simulate different working conditions and collect information such as torque, phase, and waveform. It can also perform data storage and statistics, compare the test data of new and old assemblies and form a database to facilitate subsequent fault diagnosis research. In addition, the software can perform data fusion analysis, use data analysis methods to formulate quality judgment criteria, and determine the repair quality of the assembly from multi-sensor test data. The assembly full life information platform must cover the full life cycle management of the assembly, including maintenance, placement, use and effect evaluation. It records the basic data of the assembly, such as details, warehousing, outbound, maintenance, rework records, maintenance replacement list and other information. It can also track and monitor the maintenance status, on-machine operation status and maintenance effect of the assembly through the platform and "one piece, one code" technology. In addition, the platform supports assembly life prediction and demand analysis, can perform modeling analysis and evaluate the prediction results. The platform also has expansion functions and can add relevant functions according to needs.

[0019] In summary, this invention utilizes data acquisition and analysis technology. It collects data from equipment operation, such as vibration, noise, temperature, and pressure, and processes and analyzes this data to identify any errors in the equipment's operating parameters. Furthermore, by developing a supervisory control software, it enables remote monitoring and management of equipment operating parameters, allowing for the timely detection and resolution of errors in operating parameters and data programs. Real-time monitoring of equipment operation allows for the timely identification and resolution of potential problems, improving equipment reliability and stability, and ensuring continuous and efficient production. This enables enterprises to better adapt to the demands of modern production, maintain competitiveness, and further promote social progress and development. It provides multi-source sensor data acquisition for dynamic inspection of assembly quality, improving assembly inspection efficiency and enabling comprehensive inspection and management of various assembly types. The assembly quality inspection supervisory control system of this invention can determine the quality of assembly repairs, improving the overall quality assessment capability. The assembly lifecycle information platform of this invention enables management in four aspects: basic data recording, status tracking and effect monitoring, assembly management technology application, and information platform expansion functions, thereby improving the efficiency and quality of assembly management. The assembly offline multi-condition simulation testing platform of this invention can better meet the needs of assembly maintenance and quality inspection. Attached Figure Description

Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0051] Example 1: A comprehensive quality inspection operation platform for key assemblies of a packaging and wrapping equipment, comprising the following:

[0052] Platform base 10, placed on the ground, serves as a workbench and can be used to install tools, fixture modules, and key assemblies of packaging equipment;

[0053] The tooling and fixture module includes:

[0054] Motor 20 is mounted on platform base 10 and connected to main shaft unit 30 through transmission components. It can drive main shaft unit 30 to rotate key assembly of the wrapping equipment. It is a servo motor and is controlled by main control device 70, thereby providing different operating or running conditions for dynamic inspection of key assembly of wrapping equipment and providing variable conditions for the acquisition of multi-source sensor data.

[0055] Mounting plate 40 is mounted on platform base 10 and is used to mount motor 20 and spindle unit 30; spindle unit 30 can be connected to key assemblies of rotary wrapping equipment through compatible transition flange connectors or couplings, and drive key assemblies of rotary wrapping equipment to rotate.

[0056] The lifting platform 50 is installed on the platform base 10 and can be adjusted in relative height with the plane of the platform base 10 by lifting. It is used to place key assemblies or other detection sensors of the roll packaging equipment.

[0057] The sensor mounting bracket 60 is installed on the platform base 10 and is used to install the detection sensor. The sensor can be fixed at the position to be detected and is used to measure the operating status parameters of the key assemblies of the wrapping equipment.

[0058] The tobacco conveyor belt fixing bracket 101 is installed on the platform base 10 and is used to install and fix the tobacco conveyor belt assembly 100, so that the tobacco conveyor belt 103 is suspended relative to the platform surface.

[0059] Intermittent drive unit 104 is installed on the platform base 10 and is used for transmission connection with the tobacco belt assembly 100, which can drive the tobacco belt 103 to rotate intermittently.

[0060] The detection fixing bracket 105 is installed on the platform base 10 and has two bracket plates, which are symmetrically arranged on both sides of the tobacco belt assembly 100. The plates are used to install the detection sensors 106, so that each set of detection sensors 106 is opposite to and perpendicular to the movement direction of the tobacco belt 103, and the detection sensors 106 are directly facing the thick wall of the tobacco frame 107 on the tobacco belt 103.

[0061] The main control device 70 is installed on the platform base 10 and connected to the motor 20, the sensor, the detection sensor 106 and the intermittent drive unit 104. It can control the rotation parameters of the motor 20 and receive, store and display the feedback data from the sensor; it can also acquire the signal fed back by the detection sensor 106.

[0062] The key assemblies of the wrapping equipment include:

[0063] The following components are included: a tobacco belt assembly 100, a cutter head assembly 200, a first separating drum assembly 300, a receiving drum assembly 400, a cutting disc assembly 500, a tipping paper cutter assembly 600, a small package oil seal conveyor and cutter assembly 700, an inner frame paper cutter assembly 800, a large glue cylinder assembly 900, and a small oil beauty container assembly 1000. These key assemblies of the packaging equipment can be installed on the tobacco belt fixing bracket, the main shaft unit 30, or the lifting platform 50 for testing.

[0064] When the assembly to be tested is the tobacco belt assembly 100, the intermittent drive unit 104 includes: a cam divider 108, which is installed on a support frame 109 mounted on the platform base 10 and is used to drive the tobacco belt assembly 100, enabling the tobacco belt 103 to rotate intermittently; a drive motor 110, which is mounted on the platform base 10 and connected to the cam divider 108, and is used to provide power to drive the cam divider 108 to run; the detection sensor 106 is a fiber optic through-beam sensor, with four pairs, photoelectric switch components or infrared sensors; each pair consists of two sensors arranged opposite each other. The intermittent operation of the tobacco belt 103 ensures that each time it stops, a single tobacco frame 107 stops between the four pairs of detection sensors 106, and the next time it stops, the next tobacco frame 107 also stops between the four pairs of detection sensors 106, and the positions of the four pairs of detection sensors 106 correspond to the positions of the four corners on both sides of the tobacco frame 107 when it stops.

[0065] When the key assembly of the packaging equipment, the cutter head assembly 200, is being tested, the cutter head assembly 200 is installed vertically. Its cutter head shaft is connected to the rotating shaft of the main shaft unit 30 via a coupling and a transition flange connector. The rotating shaft of the cutter head assembly 200 is placed in a vertical bearing seat from the other end. The vertical bearing seat, mounted on the lifting platform 50, is used to mount the other end of the rotating shaft of the cutter head assembly 200. The sensor used for testing is a laser displacement sensor, used as a runout detection sensor 72. The laser displacement sensor is mounted on the sensor mounting bracket 60, located directly above the cutter head assembly 200 and facing the ring line where the cigarette cutter is located on the cutter head assembly 200, used to measure the position and displacement of the rotating cigarette cutter. The sensor also includes a vibration detection sensor 71, mounted on the lifting platform 50, used to detect the vibration of the vertical bearing seat and to detect the runout of the cutter head assembly 200 during rotation.

[0066] When the key assembly of the packaging equipment is a rotating assembly that needs to be tested, the rotating shaft of the rotating assembly is connected to the rotating shaft of the main shaft unit 30 through a mutually compatible transition flange connector; the rotating assembly can rotate synchronously with the rotating shaft of the main shaft unit 30. The rotating assembly is: a first separating drum assembly 300, a receiving drum assembly 400, and a tipping paper cutter assembly 600; the detection sensor includes one or more combinations of vibration detection sensor 71, runout detection sensor 72, and temperature detection sensor 73. The vibration detection sensor 71 is mounted on the sensor mounting bracket 60, approaching the inner edge of the rotating assembly from above; the runout detection sensor 72 is mounted on the lifting platform 50, near the outer edge of the rotating assembly; and the temperature detection sensor 73 is mounted on the sensor mounting bracket 60, detecting from above the rotating shaft of the rotating assembly.

[0067] When the key assembly of the packaging equipment, the cutting disc assembly 500, needs to be inspected, the cutting disc assembly 500 is installed on the lifting platform 50, and its power drive shaft is connected to the rotating shaft of the main shaft unit 30 through a matching transition flange connector and coupling, so that the main shaft unit 30 can drive the cutting disc assembly 500 to run. The cutting disc assembly 500 includes: cutting disc assembly 500, small package oil seal conveying and cutting assembly 700, inner frame paper cutter assembly 800, large glue cylinder assembly 900, and small oil beauty container assembly 1000. The detection sensors include one or more combinations of vibration detection sensor 71, vibration detection sensor 72, and temperature detection sensor 73. The vibration detection sensor 71 and vibration detection sensor 72 are installed on the sensor mounting bracket 60 or the lifting platform 50, and can approach the surface area of ​​the cutting disc assembly 500 from above, the side, or the front. The temperature detection sensor 73 is placed or attached to the surface area of ​​the cutting disc assembly 500.

[0068] To complete the testing of the aforementioned assemblies, sensor structures need to be arranged for each assembly. Different sensor placements target different parts, requiring the cooperation of the lifting platform 50 and sensor mounting bracket 60. The lifting platform 50, in particular, not only mounts the testing sensors but also provides support when testing rotary power assemblies. Therefore, the lifting platform 50 must not only have a lifting function but also lock and fix the sensor once the height is determined, thus providing stable support. Therefore, the structure of the lifting platform 50 is as follows:

[0069] A screw jack 51 is installed below the lifting platform 50, vertically mounted on the bottom surface of the platform base 10. The lifting rod 52 of the screw jack 51 can lift the middle of the lifting platform 50 upwards. Lifting columns 53 are installed at the four corners of the lifting platform 50. The lifting columns 53 are vertically installed through the platform base 10 and can rise and fall synchronously with the lifting platform 50. A synchronous tensioning mechanism 54 is provided on the platform base 10 to lock and release the lifting columns 53. When the synchronous tensioning mechanism 54 clamps the lifting column 53, it can lock the lifting column 53 at a constant height relative to the platform base 10, thereby locking and supporting the lifting platform 50. When the synchronous tensioning mechanism 54 releases the lifting column 53, it can raise and lower the lifting column 53 relative to the platform base 10, changing the horizontal height of the lifting platform 50.

[0070] The synchronous tensioning mechanism 54 comprises four sets of equally sized connecting rods 541 rotating mechanisms interconnected and connected to a telescopic push rod 547. Each connecting rod 541 rotating mechanism includes a connecting rod 541 and a rotating coil 542. Each rotating coil 542 is equipped with two swing arms 543. One swing arm 543 is hinged to the end of one connecting rod 541, and the other end of the connecting rod 541 is hinged to the swing arm 543 of another rotating coil 542. The other swing arm 543 is hinged to the end of another connecting rod 541, and so on, hinged to each other in sequence. When one of the connecting rods 541 is pushed to swing, it can drive the other connecting rods 541 to swing synchronously, thereby driving all the rotating coils 542 to rotate synchronously in the same direction. A retaining ring 544 is installed inside the rotating coil 542, and the rotating coil 542 and the retaining ring 544 are connected to each other. When the rotating coil 542 rotates, it can drive the retaining ring 544 to rotate. The inner ring of the retaining ring 544 is provided with internal threads. A retaining spacer 545 is fitted inside the retaining ring 544. The retaining spacer 545 is narrow at the top and wide at the bottom with external threads at the top. The conical slotted sleeve has the lifting column 53 fitted inside the locking spacer 545. When the rotating coil 542 drives the locking ring 544 to rotate in the forward direction, the locking spacer 545 is raised and tightened by the internal and external threads, thus clamping the lifting column 53. The clamping of the lifting column 53 is achieved by friction. When the rotating coil 542 drives the locking ring 544 to rotate in the reverse direction, the locking spacer 545 is lowered and loosened by the internal and external threads, thus releasing the lifting column 53 and reducing friction to release the lifting column 53. The locking spacer 545 has a vertical slit for adjusting the tightness of the locking spacer 545.

[0071] One of the connecting rods 541 has its side wall hinged to the front end of the telescopic push rod 547 via a wing plate 546; the rear end of the telescopic push rod 547 is placed inside a cylinder 548, and the tail end of the cylinder 548 is hinged to a mounting plate 549, which is mounted on the platform base 10.

[0072] When installing sensors for detection, they need to be close to the detection points, especially the installation of laser-type vibration detection sensors 72, which cannot be affected by the operating equipment. Furthermore, the detection points require high precision, and different assemblies have different shapes and positions. To achieve stable placement and convenient adjustment of the installation position, a sensor mounting bracket 60 is designed. Its specific structure includes a horizontal slide rail 61 mounted on the platform base 10, and a vertical slide rail 62 mounted on the horizontal slide rail 61. The vertical slide rail 62 can slide and be fixed on the horizontal slide rail 61. A horizontal rod 63, which can slide vertically and be fixed, is installed on the vertical slide rail 62, and a detection sensor is installed on the horizontal rod 63. The sensor can move laterally on the horizontal rod 63 and stop directly above the key assembly of the packaging equipment that needs to be detected. The horizontal slide rail 61 and the vertical slide rail 62... 2. Each horizontal rod 63 is equipped with a screw motor 64 and a screw, which is used to control and adjust the relative position. The screw motor 64 is connected to the screw and can drive the screw to rotate. The tail of the vertical slide rail 62 and the horizontal rod 63 are equipped with a slider plate structure 65. The slider plate structure 65 is adapted to the screw on the horizontal slide rail 61 and the vertical slide rail 62 respectively, and can slide along the horizontal slide rail 61 and the vertical slide rail 62 as the screw rotates. A sliding plate 66 is installed on the horizontal rod 63. The sliding plate 66 is adapted to the screw on the horizontal rod 63 and can slide along the horizontal rod 63 under the rotation of the screw. The detection sensor is installed on the sliding plate 66, so that the height position, lateral position and relative position of the detection sensor with respect to the key assembly of the wrapping equipment and the detection point can be accurately adjusted, and it is not affected by the operating vibration of the key assembly of the wrapping equipment, thus improving the detection accuracy.

[0073] Example 2: Inspection of the tobacco conveyor belt assembly

[0074] The cigarette conveyor belt fixing bracket 101 includes an inverted L-shaped fixing platform. The side of the cigarette conveyor belt assembly 102 has a stop that can support it on the inverted L-shaped fixing platform so as to support the cigarette conveyor belt assembly 102 and suspend it in the air.

[0075] The detection mounting bracket 105 has four horizontal waist-shaped holes 111 on its upper part. The detection sensor 106 is installed through the waist-shaped holes 111 by the mounting assembly 112, and its relative position can be finely adjusted within the waist-shaped holes 111.

[0076] The detection sensor 106 is a fiber optic through-beam sensor, a photoelectric switch assembly, or an infrared sensor.

[0077] The abnormal condition is that at least one of the four pairs of fiber optic sensors is activated.

[0078] The cam divider 108 is also equipped with a counter or encoder, and forms a one-to-one code or number with each group of cigarette frames 107.

[0079] Install the tobacco conveyor belt fixing bracket 101 on the platform base 10 and fix it with screws.

[0080] Install two bracket plates of the detection fixing bracket 105 on both sides of the group tobacco belt fixing bracket 101, ensuring that they are perpendicular to the movement direction of the group tobacco belt 103, and fix them with screws.

[0081] Four pairs of detection sensors 106 are installed on the top of the detection fixing bracket 105 to ensure that they correspond to the four corners of the tobacco frame 107 on the tobacco belt 103. The adjustment process can be carried out through the waist-shaped hole 111. After the position is determined, the mounting component 112 is used to fix it, specifically by using a nut and a screw sleeve to achieve fixed installation.

[0082] The cigarette mold box conveyor belt assembly to be tested is placed on the cigarette belt fixing bracket 101 to ensure stable fixation. One end of the rotating hub is a drive turntable, which is mounted on the output shaft of the cam divider 108. It can be driven by the cam divider 108 to rotate the cigarette mold box with the belt. The other end of the rotating hub is installed on the platform base 10 through the cigarette belt fixing bracket 101, so that the cigarette belt 103 assembly is placed horizontally and vertically in the air. When the drive motor 110 is started, it can drive the cigarette belt 103 to rotate intermittently through the cam divider 108.

[0083] Adjust the position of the detection sensor 106, and fine-tune the spacing between the sensors by adjusting the waist-shaped hole 111 to align it with the wall thickness blocking position of the smoke frame 107.

[0084] II. Equipment Operation Procedures:

[0085] Turn on the power to the main control device 70 and start the main control display or computer.

[0086] Check if the connection between the main control device 70, the detection sensor 106, and the intermittent drive unit 104 is normal. Start the drive motor 110 power supply. When the cam divider 108 begins to rotate, mark the position of the moving tobacco frame 107 tooling with a pen as number 1. Initially, after each fixed angle rotation, according to the division pitch-angle of the tobacco belt assembly 100, each tobacco frame 107 moves to a fixed work position. This ensures that the number of rotations and the number correspond to a tobacco mold box.

[0087] III. Testing Process:

[0088] After ensuring all components are functioning correctly, start the drive motor 110 to initiate the intermittent rotation of the cam divider 108. Whenever a cigarette mold box stops, the four corners of its cigarette frame 107 align precisely with the direct line of the four pairs of detection sensors 106. The detection sensors 106 detect the wall thickness of the cigarette frame 107. If any of the four pairs of fiber optic sensors is activated, it is determined that the position or shape error of the cigarette frame 107 exceeds the deviation range, and the defective cigarette frame 107 fixture is marked with its number according to the counter on the cam divider 108. This process is repeated for all moving cigarette frames 107 to check whether their position and shape errors exceed the deviation range.

[0089] The detection sensor 106 sends feedback signals to the main control device 70 for display and storage. Upon receiving the sensor signal, the main control device 70 determines if any abnormality exists. If an abnormality occurs, the main control device 70 stops the intermittent drive unit 104, issues an alarm, and records the code number of the abnormality, which corresponds to the sequence number of the cigarette frame 107 where the abnormality occurred. It should be noted that the coding program and error signal alarm mode in this embodiment are existing mature technologies and do not involve improvements to the computer program. During the detection process, the counter or encoder on the cam divider 108 records the number of each cigarette frame 107 for subsequent data analysis.

[0090] IV. Termination and Maintenance:

[0091] After the test is completed, turn off the power to the drive motor 110 and the main control device 70.

[0092] Clean the equipment promptly and keep it clean and tidy.

[0093] Regularly inspect all parts of the equipment for damage or looseness, and repair or replace them as necessary.

[0095] Example 3: The tested assembly is the cigarette machine cutter head assembly 200.

[0096] The sensor mounting bracket 60 is mounted on the platform base 10 and is used to mount the laser displacement sensor. The laser displacement sensor is located directly above the cutter head assembly 200 and directly opposite the position of the cigarette cutter on the cutter head assembly 200. It is used to measure the position and displacement of the rotating cigarette cutter.

[0097] The cutter head assembly 200 is vertically mounted. The cutter head shaft of the cutter head assembly 200 is connected to the shaft of the main spindle unit 30 via a coupling flange, allowing the cutter head shaft to rotate synchronously with the main spindle unit 30.

The bottom of the vertical bearing housing is mounted on a base plate, which is placed on the lifting platform 50 in a movable, non-fixed manner. A vibration detection sensor 71 is mounted on this base plate, positioned close to the cutter head shaft on the lifting platform 50. The vibration detection sensor 71 is connected to the main control device 70 and is used to detect the vibration parameters of the vertical bearing housing to reflect the vibration condition of the cutter head shaft.

[0098] The main control unit 70 can control the rotation parameters of the motor 20 and receive, store, and display the feedback data from the laser displacement sensor. It can start rotating the cigarette machine cutter assembly 200 using an AC servo motor and acquire the position and displacement data of the rotating tobacco cutter measured by the laser displacement sensor. The measured data is processed by data processing software to determine whether the rotation position and displacement of the spindle blades correspond to the cutter position and displacement, and whether these meet the installation and usage accuracy requirements of the cigarette machine cutter assembly. Based on the determination results, adjustments, modifications, or replacements are made to the cigarette machine cutter assembly 200 until the installation and usage accuracy requirements of the cigarette machine cutter assembly are met.

[0101] In use, the screw jack 51 can be operated to control the height of the lifting rod 52 extending upward, thereby adjusting the relative height of the lifting platform 50 relative to the platform base 10 surface; the telescopic push rod 547 will extend or retract under the action of the cylinder 548 to realize the tightness control of the lifting column 53. When it is necessary to adjust the height of the lifting platform 50, the lifting column 53 is released, and the relative height of the lifting platform 50 can be controlled and adjusted by the screw jack 51. When the predetermined suitable height is reached, the telescopic push rod 547 moves in the reverse direction to clamp the lifting column 53. At this time, the screw jack 51 can be reset or stopped, which can maintain the relative stability of the lifting platform 50 and bear the load-bearing support force, and can install other tools.

[0102] Preferably, the lifting platform 50 is provided with a plurality of evenly arranged holes, and the vertical bearing seat is installed in the holes by fixing bolts; this facilitates the adjustment of the position of the vertical bearing seat.

[0123] Set parameters during the testing process: Input the parameters required for testing to control the movement of the servo motor, including speed and running time, to simulate different operating states of the assembly. At the same time, it can also collect the torque, phase, and waveform information of the servo motor under specific working conditions.

[0124] Data storage and statistics: Based on the collected test data, the test data of new and old assemblies are compared and stored to form an assembly test database; this is used for subsequent assembly fault diagnosis and research.

[0125] Data fusion and analysis: Based on the processing and analysis of test data, quality judgment criteria are established. Through multi-sensor test data, the repair quality of the assembly can be determined and evaluated.

[0126] The assembly quality inspection control software system includes an assembly lifecycle information platform;

[0127] The assembly lifecycle information platform takes assembly operation and maintenance data as its core, performs assembly lifecycle prediction and demand analysis, models and analyzes the lifecycle prediction, evaluates the prediction results, conducts error comparison analysis and case study applications, including: basic data recording, status tracking and effect monitoring, assembly management technology application and information platform expansion functions.

[0128] The basic data recording function can collect and record relevant basic data of assemblies, including details, warehousing, outbound, repair, rework records, repair and replacement parts list, and information on the service life of assemblies from installation to failure.

[0129] The status tracking and effect monitoring function utilizes the platform and "one piece, one code" technology to track and monitor the maintenance status, machine operation status, maintenance effect, and maintenance responsibility of the roll package assembly, and to keep track of the status of the assembly in real time.

[0130] The assembly management technology application functions include assembly life prediction and demand analysis, and attempts to model and analyze life prediction, evaluate prediction results, conduct error comparison analysis, and conduct case study applications.

[0131] To control the operation of the quality inspection platform during the testing process, the upper-level control software of the assembly repair quality inspection platform acquires relevant parameter data such as servo drive, control, and data acquisition. By inputting different parameters, it can control the speed and motion time of the servo motor and collect information such as torque, phase, and waveform under specific working conditions. By comparing the motion data of new and old assemblies, a raw database of assembly motion information can be formed, providing a basis for subsequent assembly fault diagnosis research.

[0132] To assess the quality of assemblies, static and dynamic inspection methods are established, namely, quality assessment methods that integrate mechanical inspection data and sensor data. Static inspection methods rely on mechanical measuring tools such as tooling, modules, and dial indicators, while dynamic inspection methods rely on sensor data. By applying the DS evidence theory method and combining static or dynamic indicators, criteria for judging the repair quality of assemblies can be derived, thereby significantly improving the level of condition monitoring and maintenance, and increasing production efficiency.

[0133] To address the potential characteristics and manifestations of different failure modes, machine learning and artificial intelligence technologies are used to optimize and train the fault diagnosis model, thereby improving the accuracy and reliability of fault diagnosis and establishing a comprehensive fault diagnosis indicator system. This enables timely warnings of potential fault risks, avoiding adverse impacts of equipment failures on production, while also reducing maintenance costs and downtime, and improving production efficiency and equipment operational reliability.

[0134] To achieve full lifecycle management of assemblies, a quality inspection platform is used to obtain the quality status of key assemblies, forming an application of a management model based on the entire lifecycle of assemblies. Relying on the assembly management information system, comprehensive tracking of basic record information such as details, warehousing, repair, rework, and operational status of key assemblies is achieved. By streamlining the entire assembly maintenance management process and establishing assembly management standards, a basis for full lifecycle management of assemblies is provided.

[0135] This platform will centrally manage data including basic information records of key assemblies, maintenance records, warehousing and outbound records, and on-machine operation status monitoring. Centralized data storage ensures data integrity and security; data is used for assembly life prediction and demand analysis to help companies rationally plan maintenance schedules; a "one-item-one-code" technology is used to track and monitor the maintenance status, on-machine operation status, and maintenance effectiveness of assemblies; and it also features data backup and recovery functions and user access control to address data loss or corruption and ensure data confidentiality and security.
