Description

Technical Field

[0001] This invention relates to the field of core material testing technology, and in particular to a sensor-based core material quality testing device and method. Background Technology

[0002] Currently, core material quality inspection mostly relies on manual visual inspection or single sensor detection methods. During the inspection process, it is easily affected by environmental dust, resulting in low detection accuracy and a high misjudgment rate.

[0003] Dust adhering to the surface of the core material and suspended dust in the testing environment can obstruct the view of the quality inspection probe, affecting the accuracy of image acquisition and parameter measurement. This is especially true for core material products with high precision requirements, where even tiny dust particles can cause deviations in test results.

[0004] In addition, existing testing equipment lacks an effective self-cleaning function. After long-term operation, a large amount of dust will accumulate inside the equipment, requiring frequent interruptions of the testing process for manual cleaning. This not only increases maintenance costs but also seriously affects the continuity and efficiency of production testing.

[0005] Therefore, there is an urgent need to design a core material inspection device that can effectively eliminate dust interference and has an automatic cleaning function. Summary of the Invention

Inside the cylinder, an inverted conical cylinder and multiple coaxially distributed electrostatic rings are installed. The electrostatic rings are elastically mounted on the upper side of the inverted conical cylinder. A telescopic rod is provided at the output end of each telescopic mechanism, movably inserted into the cylinder and passing through the multiple electrostatic rings. A quality inspection probe is embedded at the front end of the telescopic rod, facing the core material. An air supply device is connected externally to the airflow ring. The airflow ring has multiple upper air nozzles for real-time upward airflow output and multiple lower air nozzles for outputting airflow towards the electrostatic rings during cylinder cleaning. Multiple outwardly angled air nozzles are also provided on the top surface of the airflow ring, distributed around the upper air nozzles. A photoelectric probe is installed inside the airflow ring to detect the turbidity of the gas in the gap between the airflow ring and the core material. The cleaning component includes a brush ring in contact with the core material surface and an electromagnetic module that drives the brush ring to periodically vibrate vertically.

[0007] Preferably, the inverted conical cylinder has multiple inserts, and each electrostatic ring has multiple insert rods on its bottom side. The bottom of the insert rods is inserted into the insert, and the bottom of the insert has an elastic pad that abuts against the bottom surface of the insert rod. The vertical height of the inner electrostatic ring is greater than that of the outer electrostatic ring.

[0008] Preferably, each of the multiple electrostatic rings has a central through hole, through which the telescopic rod moves. The gap between the telescopic rod and the inner wall of the central through hole is greater than the maximum elastic displacement of the electrostatic ring in the vertical direction.

[0010] Preferably, the cylinder ring side is provided with a plurality of first through holes, and a fixing ring is installed in the first through hole. A rubber dustproof ring is provided inside the fixing ring and slides against the outer surface of the telescopic rod.

The upper air nozzle and the external oblique air nozzle are directly connected to the upper air passage, and the lower air nozzle is directly connected to the lower air passage. An upper air valve is installed between the main air passage and the upper air passage, and a lower air valve is installed between the main air passage and the lower air passage. An air supply nozzle inserted into the main air passage is also provided on the outer ring side of the airflow annular cylinder, and this nozzle is connected to the air supply equipment via an external air pipe. An inner ring component for sealing the inner circumference of the main air passage is sealed within the airflow annular cylinder, and at least two photoelectric probes are provided, embedded in the inner ring component.

[0012] Preferably, the top of the electrostatic ring is provided with a shunt tip, and the shunt tip of each electrostatic ring is aligned with a set of annularly distributed lower air nozzles.

[0013] Preferably, the cleaning component includes a fixed ring frame and a slide rod vertically disposed within the fixed ring frame. A brush ring is slidably mounted on the slide rod, and a spring is sleeved on the slide rod to elastically support the brush ring. The inner circumference of the brush ring is provided with bristles that contact the outer surface of the core material. The electromagnetic module includes an electromagnetic suction ring and a magnetic ring aligned with the electromagnetic suction ring. The cleaning component has a vibration gap, and the magnetic ring is installed within the vibration gap and fixedly connected to the brush ring. The vertical height of the vibration gap is greater than the thickness of the magnetic ring.

[0014] Preferably, a negative pressure collection device is also provided around the cylinder body, and a negative pressure pipe is provided outside the negative pressure collection device, with an air suction nozzle at the end of the negative pressure pipe facing the lower part of the brush ring of the cleaning component.

[0015] This invention also provides a sensor-based core material quality inspection method, comprising the following steps: S1. Adjusting the extension length of the telescopic mechanism according to the specifications of the core material to be inspected, so that the quality inspection probe at the front end of the telescopic rod maintains a preset distance from the outer surface of the core material. S2. Driving the core material to move vertically upward from below the cylinder, so that the core material passes through the cleaning component and the internal inspection area of ​​the cylinder in sequence.

S9. Start the electromagnetic module to drive the brush ring to vibrate periodically vertically, discharging dust outwards.

[0016] Compared with existing technologies, the beneficial effects of this invention are: This invention employs a triple protection system: brush ring pre-cleaning, airflow ring curtain protection, and electrostatic ring layered dust removal. This effectively eliminates interference from surface dust and environmental suspended dust on the core material during the testing process, significantly improving the accuracy and reliability of core material quality testing and reducing the false positive rate. Simultaneously, this invention integrates an automatic cleaning function. Through pulsed airflow impact, electrostatic ring elastic vibration, and brush ring vibration combined with negative pressure collection, it can quickly and thoroughly remove accumulated dust from the device, eliminating the need for frequent interruptions to the testing process for manual cleaning. This extends the continuous operating time of the equipment, reduces maintenance costs, and improves the efficiency of core material quality testing. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] Example 1 This invention designs a sensor-based core material quality detection device, with the specific structural configuration as follows: Combination Figure 1 , Figure 2 , Figure 3 , Figure 5The cylinder 1 is positioned around the core material 9 in vertical transmission. Multiple first through holes 11 are opened on the circumferential side of the cylinder 1. A fixing ring 12 is installed in each first through hole 11. A rubber dust-proof ring 121, which slides against the outer surface of the telescopic rod 41, is installed inside the fixing ring 12. The design of the rubber dust-proof ring 121 also prevents the telescopic rod 41 and the quality inspection probe 42 from being vibrated by the airflow transmitted from the cylinder, ensuring the detection accuracy of the quality inspection probe 42. A wire conduit 13 is fixedly installed on the circumferential side of the cylinder 1. Wires electrically connected to multiple electrostatic rings 3 are inserted through the wire conduit 13. An inverted conical cylinder 2 and multiple coaxially distributed electrostatic rings 3 are installed inside the cylinder 1. The inverted conical cylinder 2 has multiple inserts 21. Multiple insert rods 31 are installed on the bottom side of each electrostatic ring 3. The bottom of the insert rods 31 is inserted into the inserts 21. An elastic pad 22 is provided at the bottom of the inserts 21, abutting against the bottom surface of the insert rods 31. The electrostatic rings 3 are elastically mounted on the upper side of the inverted conical cylinder 2. The vertical height of the inner electrostatic ring 3 is greater than that of the outer electrostatic ring 3, giving the inner ring 3 a larger effective adsorption area and enabling it to more efficiently adsorb dust near the detection area of ​​the core material 9. Simultaneously, the multi-layered coaxial structure achieves a layered adsorption effect. The inner electrostatic ring 3 primarily adsorbs dust around itself, while the outer gas dust is adsorbed by the outer electrostatic ring 3, significantly reducing the operational burden on the inner ring 3 and preventing a large amount of dust from being concentrated there. This reduces the probability of dust detaching and escaping from the surface of the inner ring 3, thus minimizing dust interference with the quality inspection probe 42 at its source. Multiple electrostatic rings 3 are provided with central through holes 32, through which the telescopic rod 41 moves. The gap between the telescopic rod 41 and the circumferential inner wall of the central through hole 32 is greater than the maximum elastic displacement of the electrostatic ring 3 in the vertical direction. A diversion tip 33 is provided at the top of each electrostatic ring 3, and each diversion tip 33 is aligned with a set of annularly distributed lower air nozzles 56.

[0027] Combination Figure 1 , Figure 3 The telescopic mechanism 4 surrounds the cylinder 1. The output end of the telescopic mechanism 4 is provided with a telescopic rod 41 that can be inserted into the cylinder 1 and move through multiple electrostatic rings 3. The front end of the telescopic rod 41 is embedded with a quality inspection probe 42 that is directly opposite the core material 9.

[0028] Combination Figure 1 , Figure 2An airflow annular cylinder 5 is fixed at the opening on the upper side of the cylinder body 1, and an air supply device is connected to the outside of the airflow annular cylinder 5. The airflow annular cylinder 5 has a main air passage 51, an upper air passage 52, and a lower air passage 53 inside. An upper air nozzle 54 and an outer oblique air nozzle 55 are directly connected to the upper air passage 52, and a lower air nozzle 56 is directly connected to the lower air passage 53. An upper air valve 57 is installed between the main air passage 51 and the upper air passage 52, and a lower air valve 58 is installed between the main air passage 51 and the lower air passage 53. The air outlet direction of the upper air nozzle 54 is parallel to the vertical transmission direction of the core material 9, significantly reducing the impact of airflow on the core material 9 and reducing the impact of airflow vibration on the core material 9. An air supply nozzle 59, inserted into the main air passage 51, is also installed on the outer ring side of the airflow annular cylinder 5. The air supply nozzle 59 is connected to the air supply device through an external air pipe. The airflow annular cylinder 5 is sealed with an inner ring 6 for blocking the inner port of the main air passage 51. At least two photoelectric probes 61 are installed on the inner ring 6 to detect the turbidity of the gas in the gap between the airflow annular cylinder 5 and the core material 9. The airflow annular cylinder 5 is equipped with multiple upper air nozzles 54 for real-time upward airflow output and multiple lower air nozzles 56 for outputting airflow towards the electrostatic ring 3 during cylinder 1 cleaning. The top surface of the airflow annular cylinder 5 is also equipped with multiple outer oblique air nozzles 55 distributed around the upper air nozzles 54.

[0029] Combination Figure 1 , Figure 4 The cleaning component 7 is fixed at the lower opening of the cylinder 1. The cleaning component 7 includes a fixed ring frame 72 and a slide rod 73 vertically arranged within the fixed ring frame 72. A brush ring 75 is slidably mounted on the slide rod 73. A spring 74 is sleeved on the slide rod 73 to elastically support the brush ring 75. The inner circumference of the brush ring 75 is provided with bristles 76 that contact the outer surface of the core material 9. The electromagnetic module includes an electromagnetic suction ring 71 and a magnetic ring 78 aligned with the electromagnetic suction ring 71. The cleaning component 7 has a vibration gap 77, and the magnetic ring 78 is installed within the vibration gap 77, fixedly connected to the brush ring 75. The vertical height of the vibration gap 77 is greater than the thickness of the magnetic ring 78, allowing the brush ring 75 to periodically vibrate vertically under the drive of the electromagnetic module.

[0030] Combination Figure 1 , Figure 4 The outer periphery of the cylinder 1 is also equipped with a negative pressure collection device 8, and a negative pressure pipe 81 is set outside the negative pressure collection device 8. The end of the negative pressure pipe 81 is provided with an air suction nozzle 82 facing below the brush ring 75 of the cleaning component 7.

[0031] Example 2 The difference between this embodiment and Embodiment 1 is that the quality inspection probes 42 corresponding to each telescopic mechanism 4 are evenly distributed along the circumference of the cylinder 1, and the detection ranges of adjacent quality inspection probes 42 overlap to ensure that there are no blind spots on the outer surface of the core material 9. The rest of the structure is exactly the same as in Embodiment 1.

[0032] Example 3 The difference between this embodiment and Embodiment 1 is that the diameters of the coaxially distributed electrostatic rings 3 decrease sequentially, while the spacing between adjacent electrostatic rings 3 is equal. Simultaneously, the number of lower air nozzles 56 is increased accordingly, with each set of lower air nozzles 56 aligned with the top 33 of a single electrostatic ring 3, improving the cleaning effect on the multiple layers of electrostatic rings 3. The remaining structure is identical to that of Embodiment 1.

[0033] Example 4 The difference between this embodiment and Embodiment 1 is that two types of bristles 76 are evenly distributed within the inner circumference of the brush ring 75. One type of bristle is made of a stiffer nylon material to remove stubborn impurities adhering to the surface of the core material 9, while the other type of bristle is made of a softer polypropylene material to clean the surface dust of the core material 9. The two layers of bristles have different lengths, with the softer bristles being slightly longer than the stiffer bristles to ensure full contact with the surface of the core material 9. The remaining structure is exactly the same as in Embodiment 1.

[0034] Example 5 This embodiment describes a core material quality testing method based on the aforementioned device. The specific steps are as follows: First, adjust the extension length of the telescopic mechanism 4 according to the type and specifications of the core material 9 to be tested, so that the quality inspection probe 42 embedded in the front end of the telescopic rod 41 maintains a preset detection distance with the outer surface of the core material 9.

[0035] The core material 9 is driven vertically upward from below the cylinder 1 (vertical transmission avoids the sagging caused by long-distance horizontal transmission of the core material 9. If horizontal transmission is used, a larger tensioning force is required, which may cause deformation of the core material 9 and interfere with the actual quality inspection operation). The core material 9 first passes through the cleaning component 7 fixed to the lower opening of the cylinder 1. The brush ring 75 of the cleaning component 7 contacts the outer surface of the core material 9 through the bristles 76 of the inner circumference to pre-clean the floating dust attached to the surface of the core material 9.

[0036] At the same time, the upper air valve 57 of the airflow ring cylinder 5 is opened, and the external air supply equipment is started. Compressed air enters the main air passage 51 of the airflow ring cylinder 5 through the air delivery nozzle 59, and then is delivered to the upper air nozzle 54 and the outer inclined air nozzle 55 through the upper air passage 52 respectively. The airflow is output upward through the upper air nozzle 54 and outward inclined through the outer inclined air nozzle 55, forming an all-round air curtain barrier at the upper opening of the cylinder 1, preventing dust in the environment above from falling into the interior of the cylinder 1.

[0037] Simultaneously, multiple coaxially distributed electrostatic rings 3 are energized, generating an electrostatic field that adsorbs residual suspended dust in the air inside the cylinder 1. The electrostatic rings 3 adopt a multi-component layered design, which allows dust to be evenly adsorbed on different layers of electrostatic rings 3, avoiding dust concentration on the inner perimeter electrostatic rings 3 near the core material 9, and preventing dust falling off the inner perimeter electrostatic rings 3 from interfering with the quality inspection probe 42's accurate detection of the core material 9.

[0038] In addition, the photoelectric probe 61 embedded in the inner ring 6 detects the gas turbidity in the gap between the airflow ring 5 and the core material 9 in real time. When the gas turbidity exceeds the preset threshold, the control system automatically increases the gas output intensity of the gas supply equipment, increases the air outlet speed of the upper air nozzle 54 and the outer inclined air nozzle 55, enhances the protective effect of the air curtain barrier, and can discharge the excessive dust-containing gas in the gap upward.

[0039] When the core material 9 moves to the detection area inside the cylinder 1, multiple quality inspection probes 42 perform all-round scanning detection on the outer surface of the core material 9, collect surface images and dimensional parameter data of the core material 9, and transmit the data to the external control system for quality analysis and judgment.

[0040] Automatic cleaning process: When the device has accumulated a preset operating time (in which case the transmission of core material 9 needs to be paused), or when the testing of each batch of core material 9 is completed and the next batch of core material 9 has not been loaded, the control system automatically triggers the automatic cleaning process. First, the power supply to all electrostatic rings 3 is disconnected, and at the same time, the upper air valve 57 and the lower air valve 58 of the airflow ring cylinder 5 are opened, and the air supply equipment inputs pulsed compressed air into the airflow ring cylinder 5; part of the pulsed airflow is output from the nozzle through the upper air passage 52 to maintain the air curtain, and the other part is output downward from the lower air nozzle 56 through the lower air passage 53, impacting the diversion tip 33 at the top of the electrostatic ring 3.

[0041] The impact force of the pulsed airflow causes the electrostatic ring 3 to compress the elastic pad 22 through the insertion rod 31, generating up-and-down elastic vibration. The dust adsorbed on the surface of the electrostatic ring 3 is quickly detached under the impact and vibration of the airflow and moves downward with the downward airflow to the lower part of the cylinder 1, falling into the area of ​​the bristles 76 of the cleaning component 7.

[0042] At the same time, the electromagnetic module of the cleaning component 7 is activated, and the electromagnetic suction ring 71 is periodically switched on and off. Through the magnetic force between it and the magnetic ring 78, the brush ring 75 is driven to move vertically up and down along the slide bar 73 within the vibration gap 77. The spring 74 provides elastic restoring force, which makes the dust attached to the bristles 76 fall off quickly.

[0043] When the downward airflow passes through the inverted cone 2, the flow rate increases due to the reduced flow area. At the same time, the negative pressure collection device 8 is activated. A negative pressure zone is formed below the cleaning component 7 through the suction nozzle 82 at the end of the negative pressure pipe 81. The detached dust is forcibly collected by the negative pressure collection device 8 under the combined action of the high-speed airflow and the negative pressure suction, thus completing the automatic cleaning of the device.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
