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] Due to its excellent light transmittance, weather resistance and processing performance, acrylic plates are widely used in the fields of architecture, advertising, home furnishing, etc. However, during the production or use process of acrylic plates, internal defects such as cracks and bubbles are likely to occur, and the performance needs to be restored through a repair process. As a non-destructive detection method, ultrasonic flaw detection technology is widely used for defect detection, but its detection accuracy is directly affected by factors such as the cleanliness of the plate surface and the uniformity of the coupling agent coating. In the traditional detection process, the cleaning, coupling agent coating and flaw detection of the plate are mostly carried out in a step-by-step manner, resulting in problems such as low efficiency, excessive manual intervention and scattered equipment functions.

[0003] Currently, the cleaning of acrylic plates 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. Moreover, residual dirt is likely to reattach during the conveying process, affecting the accuracy of subsequent detection. The dirt collection system of existing cleaning equipment is designed roughly, and it is difficult to clean after the dirt accumulates. Long-term operation is likely to cause equipment blockage or environmental pollution. In terms of coupling agent coating, traditional equipment often uses fixed nozzles to spray directly, which is prone to problems such as uneven coating and bubble residue, resulting in attenuation or distortion of ultrasonic signals and reducing the accuracy of defect identification. In addition, the defect marking after ultrasonic flaw detection mostly relies on manual positioning, resulting in large deviations in the marking position and easy damage to the plate surface, etc., which are difficult to meet the requirements of high-precision repair. Summary of the Invention

A tensioning belt is connected between the ends of the tensioning wheel, the lower cleaning shaft and the conveying shaft.

[0014] A method for a detection device for repairing acrylic plates includes the following steps: S1. Surface cleaning treatment: The plate is conveyed through the conveyor and passes through the upper cleaning box and the lower cleaning box in sequence to clean the upper surface and the lower surface of the plate respectively; The upper surface cleaning includes: removing surface dirt with the first cleaning brush of the upper cleaning shaft, scraping off residual dirt through the blade surface of the cleaning partition, and discharging the dirt through the double-headed conveying auger via the centralized discharge pipe; the lower surface cleaning includes: removing dirt with the second cleaning brush of the lower cleaning shaft, and scraping off residual dirt with the lower scraping block; S2. Coupling agent coating: Convey the cleaned plate to the coupling box, spray the coupling agent diluent in the coupling agent storage tank onto the plate surface through the pumping cylinder, and use the scraping plate to reciprocate along the conveying direction to evenly spread the coupling agent on the plate surface; S3. Ultrasonic flaw detection: Convey the plate coated with the coupling agent under the ultrasonic flaw detection rack, and perform a full transverse scan of the plate through the probe; when a flaw is detected, trigger the marking cylinder through the controller to drive the marking pen to mark on the side wall of the plate.

[0015] The present invention provides a detection device and method for repairing acrylic plates, having the following beneficial effects: Through the synchronous design of the upper cleaning box and the lower cleaning box, the present invention realizes the dual cleaning of the upper and lower surfaces of the acrylic plate. The first cleaning brush of the upper cleaning shaft cooperates with the "herringbone" blade surface of the cleaning partition, first brushing and then scraping to thoroughly remove surface dirt, and through the spiral reverse design of the double-headed 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 scraping block synchronously clean the bottom of the plate, combined with the linkage drive of the tension belt to ensure that the rotational speeds of the upper and lower cleaning shafts and the conveying shaft are consistent, significantly improving the cleaning efficiency and synchronism. In addition, the docking design of the centralized discharge pipe and the sleeve hole directly leads the dirt into the collection box, and the magnetic suction clamping block fixes the collection box for quick disassembly and cleaning, effectively maintaining the cleanliness of the internal environment of the device.

[0016] Secondly, the drive system realizes multi-functional power distribution through a single drive shaft: the drive motor synchronously drives the upper cleaning shaft and the conveying shaft through the first gear, the second gear, and the third gear of the gear set to ensure the synchronous operation of cleaning and dirt conveying; at the same time, the meshing of the worm and the worm gear converts the rotational motion into the reciprocating linear motion of the scraping plate, and through the T-frame to link the pull rod of the pumping cylinder, realizes the timed spraying and spreading synchronization of the coupling agent. This single-axis multi-path transmission design not only simplifies the mechanical structure but also greatly reduces energy consumption and improves the coordination and stability of the device operation.

[0017] In addition, the scraping plate in the coupling box of the present invention adopts a combined design of an arc-shaped flexible retaining strip and a flattening tail plate, which can not only flexibly contact the surface of the plate to avoid scratching, but also evenly spread the coupling agent diluent sprayed by the atomizing nozzle through the reciprocating movement in cooperation with the conveying speed of the plate. The pumping cylinder realizes the quantitative spraying of the coupling agent through the precise linkage with the movement of the scraping plate, eliminates the problems of air bubbles and uneven thickness, provides a stable acoustic coupling interface for ultrasonic flaw detection, and ensures the high-precision transmission of detection signals.

[0018] In the present invention, the probes at the bottom of the ultrasonic flaw detection frame are arranged horizontally at intervals to form a full-coverage scanning area. Combining with the real-time signal analysis of the controller, internal defects of the plate can be quickly identified. The side wall positioning mark design of the marking cylinder and the marking pen avoids damage to the surface of the plate, and at the same time provides a clear position guide for subsequent repair processes. This design takes into account both detection accuracy and finished product protection, and significantly improves the repair efficiency.

[0019] In the present invention, the lifting support base adjusts the contact height between the cleaning partition and the plate by replacing pads of different thicknesses to meet the thickness requirements of various plates; the buffer spring provides flexible pressure for the cleaning partition and the lower scraping block, avoiding damage to the plate surface caused by hard contact while ensuring the scraping effect. The cooperation of the tension spring and the tension pulley automatically adjusts the tightness of the tension belt to ensure the long-term stable operation of the transmission system.

[0035] The following further elaborates and explains the specific details, implementation steps, functions and interrelationships of each feature, as well as its role in the process of implementing the present invention: The conveyor 1 serves as the transmission foundation of the overall equipment. Through the linkage of the conveyor rollers 101 and the belt 103, the continuous conveyance of the sheet 9 is realized. The conveying motor 102 at its tail provides power drive to ensure the stable movement of the sheet 9. During the conveying process, the sheet 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 a cleaning partition 403. The upper cleaning shaft 401 in the cleaning cavity initially brushes the upper surface of the sheet 9 through the first cleaning brush 4011, and the "herringbone" cutting edge of the cleaning partition 403 further scrapes off the residual dirt to prevent the secondary adhesion of the dirt. The double-headed conveying auger 4021 in the conveying cavity, through the design of opposite spiral directions, concentrates the scraped dirt from both sides to the middle and finally discharges it to the collection box 104 through the centralized discharge pipe 4023. The second cleaning brush 1202 and the lower scraping block 1203 in the lower cleaning box 12 synchronously process the lower surface of the sheet 9 to form synchronous upper and lower cleaning, ensuring that there is no residual dirt on both sides of the sheet 9 to interfere with subsequent detection.

[0036] The drive shaft 702 on the drive frame 7 is driven by a drive motor 701, and drives the upper cleaning shaft 401 and the conveying shaft 402 to rotate synchronously through gear transmission of the first gear 4012, the second gear 4022, and the third gear 7022, realizing the synchronous operation of cleaning and dirt conveying. At the same time, the drive shaft 702 converts the rotational motion into a reciprocating linear motion through the meshing of the worm 7021 and the worm wheel 703: the worm wheel 703 drives the connecting rod 1104 to drive the scraping plate 11 to reciprocate along the conveying direction of the plate 9, ensuring uniform spreading of the coupling agent; the movement of the worm wheel 703 also drives the draw rod 1004 of the pumping cylinder 10 through the T-shaped frame 1103, so that the pumping cylinder 10 completes the timed spraying of the coupling agent while the scraping plate 11 moves. This design of multi-path transmission with a single drive shaft 702 significantly improves the coordination and energy efficiency of the equipment operation.

[0037] The scraping plate 11 in the coupling box 5 is the core structure for uniform coating of the coupling agent. The compliant stop strip 1101 provided at its lower end is in flexible contact with the surface of the plate 9 to avoid scratching the plate 9, and the arc design adapts to the continuous movement of the plate 9. The pumping cylinder 10 sucks the diluent in the coupling agent storage tank 8 to the atomizing nozzle 1003 through the linkage of the draw rod 1004 and the T-shaped frame 1103 to form atomized spraying. The reciprocating movement of the scraping plate 11 is coordinated with the conveying speed of the plate 9, which not only ensures the coverage area of the coupling agent, but also eliminates bubbles and thickness unevenness through the assistance of the flattening tail plate 501, providing stable acoustic coupling conditions for subsequent ultrasonic flaw detection.

[0038] The probes 201 at the bottom of the ultrasonic flaw detection frame 2 are arranged horizontally at intervals to form a full-coverage scanning area, ensuring no missed detection in the transverse direction of the plate 9. The controller 3 analyzes the signals of the probes 201 in real time. When an internal defect is detected, it immediately triggers the marking cylinder 202 to drive the marking pen 203 to make a positioning mark on the side wall of the plate 9. This side wall marking method avoids damaging the surface of the plate 9 and is convenient for quickly positioning the defect location in subsequent repair processes.

[0039] The lifting support base 6 adjusts the thickness of the cushion block 604 to adapt to the cleaning requirements of plates 9 with different thicknesses. The buffer spring 603 provides flexible pressure for the cleaning partition 403 and the lower scraping block 1203, which not only ensures the scraping effect but also avoids damaging the surface of the plate 9 due to hard contact. The collection box 104 is fixed by the magnetic suction block 105, which is convenient for disassembly and cleaning, centrally treating dirt and dripping coupling agent, and maintaining the cleanliness inside the equipment.

[0040] The tension belt 608 connects the lower cleaning shaft 1201, the conveying shaft 402 and the tension pulley 606, and automatically adjusts the tension through the tension spring 607 to ensure the synchronous rotation speed of the upper cleaning shaft 401, the lower cleaning shaft 1201 and the conveying shaft 402, avoiding a decrease in cleaning efficiency or dirt accumulation caused by the slack of the belt 103.

[0041] The working principle of the present invention is: The sheet 9 is conveyed by the conveyor 1 and successively passes through the upper cleaning box 4 and the lower cleaning box 12 to clean the upper surface and the lower surface of the sheet 9 respectively; the upper surface cleaning includes: using the first cleaning brush 4011 of the upper cleaning shaft 401 to remove the surface dirt, scraping the residual dirt through the cutting edge surface of the cleaning spacer 403, and discharging the dirt through the double-headed conveying auger 4021 via the centralized discharge pipe 4023; the lower surface cleaning includes: using the second cleaning brush 1202 of the lower cleaning shaft 1201 to remove the dirt, and scraping the residual dirt through the lower scraping block 1203; the upper cleaning shaft 401 and the conveying shaft 402 are meshed and driven by the first gear 4012 and the second gear 4022 to drive the first cleaning brush 4011 and the double-headed conveying auger 4021 to rotate synchronously, so as to realize the synchronous operation of dirt removal and conveying. The lower cleaning shaft 1201 is linked with the conveying shaft 402 through the tension belt 608 to ensure the synchronous cleaning of the upper and lower surfaces; The cleaned sheet 9 is conveyed to the coupling box 5, and the coupling agent diluent in the coupling agent storage tank 8 is sprayed onto the surface of the sheet 9 through the pumping cylinder 10, and the scraping plate 11 reciprocates along the conveying direction to evenly spread the coupling agent on the surface of the sheet 9. The reciprocating movement of the scraping plate 11 is realized by the meshing drive 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 along the conveying direction. The spraying of the coupling agent by the pumping cylinder 10 is synchronized with the movement of the scraping plate 11, and the reciprocating movement of the T-shaped frame 1103 is linked through the pull rod 1004 to realize the timed and quantitative spraying of the coupling agent; The sheet 9 coated with the coupling agent is conveyed under the ultrasonic flaw detection frame 2, and the sheet 9 is scanned horizontally and completely covered by the probe 201; when a flaw is detected, the marking cylinder 202 is triggered by the controller 3 to drive the marking pen 203 to mark on the side wall of the sheet 9. The detection signal of the probe 201 is transmitted to the controller 3. When a defect exists inside the sheet 9, the controller 3 controls the piston rod of the marking cylinder 202 to extend, so that the marking pen 203 makes a positioning mark on the side wall of the sheet 9; The dirt generated during the cleaning process and the dripping coupling agent diluent are guided to 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 suction chuck 105 for centralized treatment; By changing the thickness of the cushion block 604, the relative height of the end block 503 and the supporting block 601 is adjusted to adapt to sheets 9 of different thicknesses, and the buffer spring 603 provides a flexible pressure when the cleaning spacer 403 contacts the sheet 9.
