Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a detection equipment and method for repairing acrylic plates. Background Art

[0002] Acrylic sheets are widely used in construction, advertising, home furnishings, and other fields due to their excellent light transmittance, weather resistance, and processing properties. However, acrylic sheets are prone to internal defects such as cracks and bubbles during production or use, requiring repair processes to restore their performance. Ultrasonic flaw detection technology, as a non-destructive testing method, is widely used for defect detection, but its detection accuracy is directly affected by factors such as the surface cleanliness of the sheet and the uniformity of the coupling agent coating. In traditional testing processes, sheet cleaning, coupling agent coating, and flaw detection are often performed in a step-by-step manner, resulting in low efficiency, frequent manual intervention, and dispersed equipment functions.

[0003] Currently, the cleaning process of acrylic sheets mostly relies on single-sided cleaning devices, and the upper and lower surfaces need to be processed step by step, resulting in low cleaning efficiency. Residual dirt is easily attached to the surface during transportation, affecting the accuracy of subsequent inspections. The dirt collection system of existing cleaning equipment is crudely designed, making it difficult to clean after dirt accumulates. Long-term operation can easily cause equipment blockage or environmental pollution. In terms of coupling agent coating, traditional equipment often uses fixed nozzles for direct spraying, which is prone to problems such as uneven coating and residual bubbles, causing ultrasonic signal attenuation or distortion, reducing the accuracy of defect identification. In addition, defect marking after ultrasonic testing mostly relies on manual positioning, which has problems such as large deviation in marking position and easy damage to the surface of the board, making it difficult to meet the needs of high-precision repair.

[0016] A method for detecting equipment for repairing acrylic panels, comprising the following steps:

[0017] S1. Surface cleaning: The sheet material is transported by a conveyor and sequentially passes through the upper cleaning box and the lower cleaning box to clean the upper and lower surfaces of the sheet material respectively;

[0018] The upper surface cleaning comprises: using the first cleaning brush of the upper cleaning shaft to remove surface dirt, scraping off residual dirt with the blade surface of the cleaning partition, and discharging the dirt through the centralized discharge pipe by the double-head conveying auger; the lower surface cleaning comprises: using the second cleaning brush of the lower cleaning shaft to remove dirt, and scraping off residual dirt with the lower scraping block;

[0019] S2. Coupling Agent Application: The cleaned sheet material is conveyed to the coupling agent tank. The coupling agent dilution liquid in the coupling agent tank is sprayed onto the sheet material surface via a pumping cylinder. A scraper is then moved back and forth along the conveying direction to evenly spread the coupling agent over the sheet material surface.

[0020] S3. Ultrasonic testing: The coupling agent-coated plate is transported to the bottom of the ultrasonic testing frame, and the probe is used to scan the plate horizontally and fully. When a defect is detected, the controller triggers the marking cylinder, driving the marking pen to mark the side wall of the plate.

[0021] The present invention provides an acrylic plate repair detection device and method, which has the following beneficial effects:

[0022] The present invention achieves double cleaning of the upper and lower surfaces of the acrylic plate through the synchronous design of the upper cleaning box and the lower cleaning box. The first cleaning brush of the upper cleaning shaft cooperates with the "human" shaped blade surface of the cleaning partition to first brush and then scrape to thoroughly remove surface dirt, and through the spiral reverse design of the double-head conveying auger, the dirt is concentrated from both sides to the middle discharge pipe to avoid secondary pollution. The second cleaning brush of the lower cleaning box and the lower scraper block synchronously clean the bottom of the plate. Combined with the linkage transmission of the tensioning belt, the rotation speed of the upper and lower cleaning shafts and the conveying shaft is ensured to be consistent, which significantly improves the cleaning efficiency and synchronization. In addition, the docking design of the centralized discharge pipe and the sleeve hole directly guides the dirt into the collection box, and the magnetic card block fixes the collection box for quick disassembly and cleaning, effectively maintaining the cleanliness of the internal environment of the equipment.

[0023] Secondly, the drive system achieves multifunctional power distribution through a single drive shaft: the drive motor synchronously drives the upper cleaning shaft and the conveying shaft through the first, second, and third gears of the gear train, ensuring the synchronization of cleaning and dirt conveying. At the same time, the meshing of the worm and worm wheel converts rotational motion into reciprocating linear motion of the scraper plate. This T-frame links the extraction rod of the pumping cylinder to achieve synchronized timed spraying and paving of the coupling agent. This single-shaft, multi-path transmission design not only simplifies the mechanical structure, but also significantly reduces energy consumption and improves the coordination and stability of equipment operation.

[0024] Furthermore, the scraper plate in the coupling box of this invention utilizes a combination of curved, flexible baffles and a flattening tail plate. This design not only allows for flexible contact with the sheet surface to prevent scratches, but also coordinates reciprocating motion with the sheet conveying speed to evenly spread the couplant dilution sprayed by the atomizing nozzle. The pumping cylinder, through precise linkage between the pull-out rod and the scraper plate's movement, achieves quantitative couplant spraying, eliminating air bubbles and uneven thickness. This provides a stable acoustic coupling interface for ultrasonic testing and ensures high-precision transmission of test signals.

[0025] The probes at the bottom of the ultrasonic flaw detection stand are arranged horizontally and spaced apart, creating a fully covered scanning area. Combined with the controller's real-time signal analysis, this method allows for rapid identification of internal defects in sheet metal. The marking cylinder and pen's sidewall positioning marks prevent damage to the sheet metal surface while providing clear positioning guidance for subsequent repair processes. This design balances detection accuracy with product protection, significantly improving repair efficiency.

[0026] The lifting support base adjusts the contact height between the cleaning spacer and the sheet material by replacing pads of varying thicknesses, accommodating a wide range of sheet thicknesses. A buffer spring provides flexible pressure between the cleaning spacer and the lower scraper, ensuring effective scraping while preventing damage to the sheet material surface caused by hard contact. The tensioning spring and tensioning pulley automatically adjust the tension of the tensioning belt, ensuring long-term stable operation of the transmission system. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The following further describes and illustrates the specific details, implementation steps, functions and interrelationships of the above features, as well as their roles in implementing the present invention:

[0073] The conveyor 1 serves as the transmission basis of the entire equipment. Through the linkage between the conveying roller 101 and the belt 103, the continuous conveying of the plate 9 is achieved. The conveying motor 102 at the rear provides power drive to ensure the smooth movement of the plate 9. During the conveying process, the plate 9 first enters the cleaning system composed of the upper cleaning box 4 and the lower cleaning box 12. The interior of the upper cleaning box 4 is divided into a cleaning cavity and a conveying cavity by the cleaning partition 403. The upper cleaning shaft 401 in the cleaning cavity performs a preliminary scrubbing of the upper surface of the plate 9 with the first cleaning brush 4011, and the "human" shaped blade surface of the cleaning partition 403 further scrapes off residual dirt to prevent secondary attachment of dirt. The double-headed conveying auger 4021 in the conveying cavity is designed with opposite spiral directions to concentrate the scraped dirt from both sides to the middle, and finally discharge it to the collection box 104 through the centralized discharge pipe 4023. The second cleaning brush 1202 and the lower scraper 1203 in the lower cleaning box 12 simultaneously process the lower surface of the plate 9, forming upper and lower synchronous cleaning, ensuring that there is no residual dirt on both sides of the plate 9 to interfere with subsequent detection.

[0074] The drive shaft 702 on the drive frame 7 is driven by a drive motor 701. This gear transmission, through the first gear 4012, the second gear 4022, and the third gear 7022, synchronously drives the upper cleaning shaft 401 and the conveying shaft 402, achieving synchronized operation of cleaning and dirt conveying. Simultaneously, the drive shaft 702's rotational motion is converted into reciprocating linear motion through the meshing of the worm 7021 and the worm gear 703. The worm gear 703 drives the connecting rod 1104, which drives the scraping plate 11 back and forth along the conveying direction of the plate 9, ensuring uniform spreading of the coupling agent. The movement of the worm gear 703 also links the pull rod 1004 of the pumping cylinder 10 through the T-frame 1103, allowing the pumping cylinder 10 to spray the coupling agent in a timed manner while the scraping plate 11 moves. This multi-path transmission design of a single drive shaft 702 significantly improves the coordination and energy efficiency of the equipment's operation.

[0075] The scraper plate 11 in the coupling box 5 is the core structure for uniform couplant coating. A compliant barrier strip 1101 at its lower end provides flexible contact with the surface of the sheet 9 to prevent scratching, while its curved design accommodates the continuous movement of the sheet 9. The pumping cylinder 10, linked by a pull rod 1004 and a T-frame 1103, draws the diluent from the couplant tank 8 into the atomizing nozzle 1003, creating an atomized spray. The reciprocating motion of the scraper plate 11, coordinated with the conveying speed of the sheet 9, ensures couplant coverage and, with the assistance of the flattening tail plate 501, eliminates air bubbles and uneven thickness, providing stable acoustic coupling conditions for subsequent ultrasonic testing.

[0076] Probes 201 at the bottom of the ultrasonic flaw detection stand 2 are arranged in a horizontally spaced arrangement, creating a fully covered scanning area and ensuring that no lateral defects are missed in the plate 9. The controller 3 analyzes the signals from the probes 201 in real time. When an internal defect is detected, it immediately triggers the marking cylinder 202, which drives the marking pen 203 to mark the sidewall of the plate 9. This sidewall marking method avoids damage to the surface of the plate 9 and facilitates rapid location of defects in subsequent repair processes.

[0077] The lift support 6 is adjustable via the thickness of the pad 604 to accommodate cleaning requirements for plates 9 of varying thicknesses. The buffer spring 603 provides flexible pressure to the cleaning spacer 403 and lower scraper 1203, ensuring effective scraping while preventing hard contact and damage to the surface of the plate 9. The collection box 104 is secured with a magnetic card 105, making it easy to disassemble and clean, centrally disposing of dirt and dripping coupling agent, and maintaining a clean interior.

[0078] The tensioning belt 608 connects the lower cleaning shaft 1201, the conveying shaft 402 and the tensioning wheel 606, and automatically adjusts the tension through the tensioning spring 607 to ensure that the rotation speed of the upper cleaning shaft 401, the lower cleaning shaft 1201 and the conveying shaft 402 are synchronized, avoiding the reduction of cleaning efficiency or dirt accumulation due to the relaxation of the belt 103.

[0079] The working principle of the present invention is:

[0080] The plate 9 is transported by the conveyor 1 and passes through the upper cleaning box 4 and the lower cleaning box 12 in sequence, and the upper surface and lower surface of the plate 9 are cleaned respectively; the upper surface cleaning includes: using the first cleaning brush 4011 of the upper cleaning shaft 401 to remove surface dirt, scraping off residual dirt through the blade surface of the cleaning partition 403, and discharging the dirt through the centralized discharge pipe 4023 by the double-head conveying auger 4021; the lower surface cleaning includes: using the second cleaning brush 1202 of the lower cleaning shaft 1201 to remove dirt, and scraping off residual dirt through the lower scraping block 1203; the upper cleaning shaft 401 and the conveying shaft 402 are engaged with each other through the first gear 4012 and the second gear 4022 to drive the first cleaning brush 4011 and the double-head conveying auger 4021 to rotate synchronously to achieve synchronous operation of dirt removal and conveying, and the lower cleaning shaft 1201 is linked to the conveying shaft 402 through the tensioning belt 608 to ensure that the upper and lower surfaces are cleaned synchronously;

[0081] The cleaned plate 9 is conveyed to the coupling box 5. The coupling agent dilution liquid in the coupling agent storage tank 8 is sprayed onto the surface of the plate 9 via the pumping cylinder 10. The scraping plate 11 is reciprocated in the conveying direction to evenly spread the coupling agent on the surface of the plate 9. The reciprocating movement of the scraping plate 11 is achieved by the meshing transmission of the worm 7021 of the drive shaft 702 and the worm gear 703. The rotation of the worm gear 703 drives the connecting rod 1104 to drive the scraping plate 11 to reciprocate in the conveying direction. The coupling agent spraying of the pumping cylinder 10 is synchronized with the movement of the scraping plate 11. The reciprocating movement of the T-frame 1103 is linked by the pull rod 1004 to achieve timed and quantitative spraying of the coupling agent.

[0082] The plate 9 coated with coupling agent is conveyed to the bottom of the ultrasonic flaw detection frame 2, and the plate 9 is scanned horizontally and fully covered by the probe 201. When a defect is detected, the marking cylinder 202 is triggered by the controller 3, driving the marking pen 203 to mark the side wall of the plate 9. The detection signal of the probe 201 is transmitted to the controller 3. When a defect is detected inside the plate 9, the controller 3 controls the piston rod of the marking cylinder 202 to extend, causing the marking pen 203 to mark the side wall of the plate 9.

[0083] The dirt and dripping coupling agent dilution generated during the cleaning process are guided into the collection box 104 through the centralized discharge pipe 4023 and the sleeve hole 1204, and the collection box 104 is fixed by the magnetic card block 105 for centralized treatment;

[0084] The relative height between the end block 503 and the support block 601 is adjusted by changing the thickness of the spacer block 604 to adapt to plates 9 of different thicknesses, and the buffer spring 603 provides flexible pressure when the cleaning partition 403 contacts the plate 9 .
