Description

Technical Field

[0001] The present application relates to the technical field of glue quality detection, and in particular to a packaging box glue dispensing detection device and detection method. Background Art

[0002] Packaging boxes occupy an important position in modern product packaging and are widely used in many industries such as food, cosmetics, electrical appliances, and daily necessities. They are mainly used to protect products, facilitate transportation and display, and are also an important carrier for conveying brand image. The design and manufacture of packaging boxes directly affect product safety and user experience. As the market's requirements for packaging quality continue to increase, higher standards are put forward for various performance indicators of packaging boxes during the production process, such as sealing and compressive strength.

[0003] In the production of packaging boxes, the glue dispensing process is a key link to ensure the structural integrity and sealing performance of the box body. The quality of glue dispensing is directly related to the durability and moisture-proof performance of the packaging box, so effective glue dispensing detection becomes an important step to ensure product quality.

[0004] Traditionally, the main methods for gluing inspection on packaging boxes include the following: visual inspection by manually checking the glue coating to observe the uniformity of glue dispensing and the coating position; gravimetric inspection by comparing the weight of the packaging box before and after gluing to determine whether the amount of glue meets the requirements; liquid fluidity inspection by testing the viscosity and fluidity of the glue to determine its suitability for coating; mechanical vibration testing by performing external vibration tests on the bonded points to detect the bonding strength of the glue; and image detection systems that use image recognition technology to analyze the glue coating status by taking pictures of the packaging box with a camera.

[0005] The above-mentioned dispensing detection method has shortcomings when inspecting packaging boxes, especially when dispensing glue on special-shaped packaging boxes: First, visual inspection relies on manual operation, which is prone to missed detection or false detection due to subjective factors, especially in areas with complex shapes. Secondly, the weight method can only reflect the total amount of glue used, but cannot determine the distribution of glue on special-shaped packaging boxes, especially in concave or irregular edge parts, which may make insufficient glue coating difficult to detect. In addition, although liquid fluidity detection can provide viscosity information, there is no real-time feedback and the dispensing process cannot be adjusted in time. Similarly, mechanical vibration testing is mainly aimed at bonded products and lacks effective monitoring of the dispensing process.

[0006] In addition, the image detection system has poor adaptability to special-shaped packaging boxes and may not be able to accurately identify all glue-coated areas. The dependence on equipment and technology increases operating costs.

[0007] Therefore, a more advanced and reliable detection solution is urgently needed to timely identify and correct potential quality defects during the dispensing process to ensure the final quality of special-shaped packaging boxes. Summary of the invention

[0008] In order to detect and correct the glue dispensing quality of special-shaped packaging boxes to ensure the final quality of the special-shaped packaging boxes, the present application provides a packaging box glue dispensing detection device and detection method.

[0009] The present application provides a packaging box dispensing detection device, which adopts the following technical solution: A packaging box glue dispensing detection device is used to detect the glue quality of the inner wall of the packaging box, comprising a detection table, a clamping mechanism for clamping and fixing the packaging box is arranged on the detection table, a mounting frame is arranged above the clamping mechanism, and a lifting mechanism for driving the mounting frame to extend into the packaging box and a tracking mechanism for driving the mounting frame to move along the contour of the inner wall of the packaging box are arranged on the detection table; The mounting frame is provided with a detection mechanism for detecting the glue quality of the inner wall of the packaging box, and the mounting frame is also provided with a repair mechanism for repairing the defective glue detected by the detection mechanism; When the detection mechanism detects that there is a defect in the glue position, the repair mechanism can extend into the glue and perform vibration repair on the bubbles and cracks in the glue.

[0010] By adopting the above technical solution, when it is necessary to inspect the glue quality of the glue part in the packaging box, the lifting mechanism is controlled to descend so that the detection mechanism descends to the glue position. At this time, the tracking mechanism drives the detection mechanism to move along the extension direction of the glue for detection. When a defect is detected in the glue position, the repair end of the repair mechanism extends into the glue and vibrates and repairs the bubbles and cracks in the glue, thereby ensuring the final quality of the special-shaped packaging box.

[0011] Optionally, the detection mechanism includes an ultrasonic transmitter and an ultrasonic receiver arranged at intervals on the mounting frame, and the ultrasonic transmitter and the ultrasonic receiver are respectively located on both sides of the glue position. The detection mechanism also includes a controller arranged on the mounting frame, and the controller is electrically connected to the ultrasonic transmitter, ultrasonic receiver, detection mechanism, tracking mechanism and repair mechanism, respectively.

[0012] By adopting the above technical solution, when the mounting frame moves to the glue detection position, the ultrasonic transmitter emits ultrasonic waves, which pass through the glue and are received by the ultrasonic receiver, thereby capturing bubbles and cracks inside the glue. The controller coordinates the work of various components, collects and analyzes ultrasonic signals, and ensures high accuracy and sensitivity of detection. The electrical connection between the controller and the tracking mechanism and the repair mechanism realizes the linkage of fully automatic detection, data feedback and repair operations, avoiding manual intervention and reducing the false detection rate.

[0013] Optionally, the repair mechanism includes a micro-oscillation glue repair component and a dual-state hot and cold collaborative repair component, the micro-oscillation glue repair component is used to perform vibration repair on internal defects of the glue, the dual-state hot and cold collaborative repair component is used to perform heat treatment on the surface of the glue when the micro-oscillation glue repair component is extended into the glue, and is used to perform cold treatment on the surface of the glue when the micro-oscillation glue repair component is extended out of the glue.

[0014] By adopting the above technical solution, the micro-oscillation glue repair component uses vibration to treat the internal defects of the glue, so that the bubbles burst, the glue is redistributed, and the sealing performance is restored. The dual-state hot and cold collaborative repair component uses hot air softening and cold air curing. When the repair end of the micro-oscillation glue repair component enters the inside of the glue, it can heat the surface of the glue, thereby softening the surface of the glue, making it easier for the repair end to extend into the inside of the glue, and can also heat the inside of the glue to a certain extent, and achieve better repair effects with vibration, optimizing the strength and uniformity of the glue after glue repair.

[0015] And the surface of the glue can be briefly cooled after the repair end is pulled out of the glue, so that the temperature of the outer surface of the glue is reduced, and the fluidity of the outer surface of the glue is less than the fluidity of the inside of the glue, so that a protective layer is formed on the outer surface of the glue, and the flow protection of the internal glue is realized, and the internal glue escape is reduced, so that the shape of the repaired glue can be maintained, and the repaired glue can ensure the internal flow bonding performance while not escaping, thereby greatly improving the repair effect.

[0017] By adopting the above technical solution, when the telescopic part drives the repair needle into the glue, the vibration transmission column extends into the perforation of the vibration table. At this time, the vibration of the vibration part is transmitted to the repair needle through the vibration table and the vibration transmission column, so that the repair needle can perform vibration repair on defects such as bubbles and fractures inside the glue.

[0018] Optionally, the vibration table is mounted on the detection table, and a plurality of groups of elastic support components for reducing vibrations transmitted from the vibration table to the mounting frame are arranged between the vibration table and the detection table.

[0019] By adopting the above technical solution, multiple groups of elastic support components absorb excess energy transmitted to the mounting frame by vibration, reduce the overall structural shaking caused by vibration, and extend the service life of the equipment.

[0020] Optionally, the dual-state hot and cold coordinated repair component includes a shaping cover, a rotary cylinder, a dual-state hot and cold annular cavity, a hot air supply bin and a cold air supply bin, one side of the shaping cover is hollow in an arc shape, and the other side is hollow in a cylindrical shape, and the arc-shaped hollow inner cavity is connected to the cylindrical hollow inner cavity, and a channel for the repair needle to pass through is opened in the middle of the arc-shaped and cylindrical inner cavities of the shaping cover, and the arc-shaped and cylindrical inner cavities of the shaping cover are not connected to the channel; The arc-shaped inner side wall of the shaping cover is adapted to the outer surface profile of the standard glue, and a plurality of air outlet nozzles are embedded at intervals on the arc-shaped side wall of the shaping cover, and the end of each of the air outlet nozzles is flush with the arc-shaped side wall of the shaping cover; The rotating cylinder and the dual-state hot and cold annular cavity are fixedly connected and are both slidably sleeved outside the repair needle. The end of the dual-state hot and cold annular cavity away from the rotating cylinder is rotatably connected to the cylindrical end of the shaping cover, and the inner cavities of the two are interconnected and a rotational seal is arranged at the connection; A thread groove is provided on the inner wall of the rotary cylinder, and an insertion rod adapted to the thread groove is provided on the outer wall of the repair needle; The hot air supply bin and the cold air supply bin are respectively located on both sides of the repair needle, a gap is surrounded between the hot air supply bin and the cold air supply bin for the dual-state hot and cold ring cavity to pass through, and air outlet holes are provided on the hot air supply bin and the cold air supply bin, and both air outlet holes are provided with air valves that open inward in one direction, and a valve-opening ball for pressing the air valve to open is provided on the outer wall of the dual-state hot and cold ring cavity corresponding to the air outlet hole, and the valve-opening ball is elastically retractable and arranged on the outer wall of the dual-state hot and cold ring cavity, and when the valve-opening ball is retracted, the valve-opening ball is flush with the outer wall of the dual-state hot and cold ring cavity, and an airflow hole that passes through the inside and outside of the dual-state hot and cold ring cavity is provided on the valve-opening ball; The diameter of the cylindrical side of the shaping cover is smaller than the diameter of the dual-state hot and cold annular cavity, and the diameter of the dual-state hot and cold annular cavity is adapted to the gap between the hot air supply bin and the cold air supply bin.

[0021] By adopting the above technical solution, when the telescopic member drives the repair needle to be inserted into the glue, the end of the plastic cover first abuts against the inner wall of the packaging box, and the plastic cover fits the outer peripheral wall of the glue. At this time, the dual-state hot and cold ring cavity is inserted into the gap between the hot air supply chamber and the cold air supply chamber; Then the telescopic part continues to drive the repair needle to move and insert it into the glue. At this time, the insertion rod on the repair needle will drive the rotary cylinder to rotate, and the rotary cylinder drives the dual-state hot and cold ring cavity to rotate. The valve opening ball on the dual-state hot and cold ring cavity rotates to face the air outlet on the hot air supply bin. At this time, the valve opening ball opens the air valve, and the hot air in the hot air supply bin enters the inner cavity of the shaping cover and is finally ejected from the air outlet nozzle, thereby heating the surface of the glue, so that the repair needle can better repair the defective part. When the repair is completed, the telescopic part drives the repair needle to be pulled out of the glue. During this process, the rod first drives the rotary drum to rotate, and the rotary drum drives the dual-state hot and cold ring cavity to rotate, so that the valve opening ball rotates to face the air outlet of the cold air supply bin. At this time, the valve opening ball opens the air valve on the cold air supply bin to allow cold air to enter the plastic cover, thereby briefly spraying cold air on the outer surface of the repaired glue, ensuring the adhesion performance of the glue inside while reducing the stickiness of the outer surface, and also ensuring the escape protection of the internal repaired glue, so that the quality of the repaired glue is better.

[0022] Optionally, the tracking mechanism includes a power piece, a track, a support plate, a connecting rod, a slide seat and a limit column, the power piece is installed on the detection platform and is located above the packaging box, the track is detachably installed on the inner wall of the detection platform, and the shape of the track is consistent with the contour of the inner wall of the packaging box to be detected, the support plate is fixed to the end of the power piece and is perpendicular to the output end of the power piece, and the support plate is provided with a slide groove along the length direction; One end of the connecting rod is fixedly connected to the mounting frame, and two limiting posts are provided. The two limiting posts are spaced apart and arranged at the other end of the connecting rod, and the two limiting posts extend to the inner and outer sides of the track respectively; The slide seat is slidably engaged in the slide slot and fixedly sleeved on the connecting rod. A first elastic member is arranged in the slide slot to drive the slide seat to move away from the output end of the power member. The upper and lower connecting rods of the slide seat are respectively an upper rod and a lower rod. The ends of the upper rod and the lower rod are elastically and movably connected. The lower rod can be displaced a certain distance along the length direction of the support plate, and the lower rod tends to move in a direction away from the output end of the power member.

[0023] By adopting the above technical solution, when the power part is working, it will drive the support plate to rotate. At this time, the track will drive the connecting rod to move. Under the action of the first elastic part, the end of the mounting frame will stably abut along the inner wall of the packaging box, thereby realizing stable detection of the glue.

[0024] Optionally, the lifting mechanism includes a driving member, a screw rod and a guide rod. A mounting plate is provided on the detection platform, the tracking mechanism is provided on the mounting plate, the driving member is provided on the detection platform, the screw rod is coaxially fixed with an output end of the driving member, the screw rod passes through the mounting plate and is threadedly connected to the mounting plate, a plurality of guide rods are provided, each of the guide rods is parallel to each other, and is fixedly connected to the detection platform after passing through the mounting plate.

[0025] By adopting the above technical solution, when it is necessary to detect the glue in the packaging box, the driving member is controlled to work, and the driving member drives the screw rod to rotate, thereby realizing the lifting and lowering control of the mounting plate, so that the mounting frame can be moved to the glue position.

[0026] Optionally, the clamping mechanism includes a clamping seat and a plurality of clamping blocks arranged on the clamping seat, a space for placing the packaging box is reserved between each clamping block, and a plurality of second elastic members are arranged in the clamping seat corresponding to each clamping block, and each second elastic member is used to drive the corresponding clamping block to move in a direction close to each other.

[0027] By adopting the above technical solution, when the packaging box needs to be clamped and fixed, the clamping blocks are opened, the packaging box is placed in the space between the clamping blocks, and then the clamping blocks are loosened so that the clamping blocks can clamp and fix the outer wall of the packaging box.

[0028] The present invention also provides a packaging box glue dispensing detection method, which is applied to the above packaging box glue dispensing detection device and comprises the following steps: S1: Push apart the clamps, place the packaging box in the space between the clamps, and then loosen the clamps so that the clamps clamp and fix the outer wall of the packaging box; S2: Control the lifting mechanism to descend, so that the mounting frame moves toward the glue position in the packaging box. When the end of the mounting frame moves to the upper end of the packaging box, move the lower rod toward the output end of the power component, so that the end of the mounting frame bypasses the glue position until the middle cavity position of the mounting frame is aligned with the glue position, and then release the lower rod; S3: Start the power part, so that the power part drives the mounting frame to move along the inner wall of the packaging box. At this time, the detection mechanism performs ultrasonic quality detection on the inside of the glue. When it is detected that there is a defect in the glue position, the telescopic part drives the detection needle to extend into the glue. At this time, the vibration part transmits the vibration to the detection needle, so that the detection target performs vibration repair on the defective part, and the shaping cover is connected to the hot air supply bin, and the air outlet nozzle sprays hot air on the surface of the glue; S4: After a short vibration repair, the telescopic part drives the detection needle to be pulled out from the inside of the glue. When the detection needle is completely pulled out from the inside of the glue, the vibration part no longer vibrates. At this time, the shaping cover is connected to the cold air supply compartment, and the air outlet nozzle sprays cold air to the surface of the glue, thereby completing the repair of the inside of the glue and the protection of the outer surface of the glue from glue leakage.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. This application aims at the demand for glue quality inspection and repair of the complex inner wall of special-shaped packaging boxes. By using a tracking mechanism and a lifting mechanism, the inspection and repair device can flexibly follow the contour of the inner wall of the packaging box to achieve comprehensive coverage inspection and repair of complex areas such as depressions and edges. This flexibility is difficult to achieve with traditional inspection methods; 2. This application integrates ultrasonic detection and micro-oscillation repair technology to achieve the function of real-time detection of glue defects and immediate repair, breaking through the inefficiency caused by the separation of traditional detection and repair. Through dynamic feedback and synchronous repair, it can significantly improve production efficiency and ensure glue quality; 3. The micro-oscillation glue repair component in the present application can process the internal defects of the glue by vibration, so that the bubbles burst, the glue is redistributed, and the sealing performance is restored. The dual-state hot and cold collaborative repair component can utilize the hot air softening and cold air curing effects. In the process of the repair end of the micro-oscillation glue repair component entering the inside of the glue, the surface of the glue can be heated, thereby softening the surface of the glue, so that the repair end can be more easily inserted into the inside of the glue, and the inside of the glue can also be heated to a certain extent, and a better repair effect can be achieved with vibration, and the strength and uniformity of the glue after the glue repair are optimized; 4. After the repair needle completes the repair of the inside of the glue, the dual-state hot and cold collaborative repair component can also briefly cool the surface of the glue, thereby reducing the temperature of the outer surface of the glue, making the fluidity of the outer surface of the glue less than the fluidity of the inside of the glue, thereby forming a protective layer on the outer surface of the glue, protecting the flow of the internal glue, reducing the escape of the internal glue, and maintaining the shape of the repaired glue, so that the repaired glue can ensure the internal flow and bonding performance while not escaping, thereby greatly improving the repair effect.

[0032] The following is combined with Figure 1-6 , further details of this application are given.

[0033] The embodiment of the present application discloses a packaging box glue dispensing detection device.

[0034] Reference Figure 1 , Figure 2 and Figure 3 , a packaging box glue dispensing detection device, used for detecting the glue quality of the inner wall of the packaging box 13, comprising a detection table 1, a clamping mechanism 2 for clamping and fixing the packaging box 13 is arranged on the detection table 1, a mounting frame 5 is arranged above the clamping mechanism 2, and a lifting mechanism 3 for driving the mounting frame 5 to extend into the packaging box 13 and a tracking mechanism 4 for driving the mounting frame 5 to move along the contour of the inner wall of the packaging box 13 are arranged on the detection table 1; The mounting frame 5 is provided with a detection mechanism 6 for detecting the quality of glue on the inner wall of the packaging box 13, and the mounting frame 5 is also provided with a repair mechanism 7 for repairing the defective glue detected by the detection mechanism 6; When the detection mechanism 6 detects that there is a defect in the glue position, the repair mechanism 7 can extend into the glue and perform vibration repair on the bubbles and cracks in the glue.

[0035] When it is necessary to inspect the glue quality of the glue position in the packaging box 13, the lifting mechanism 3 is controlled to descend, so that the detection mechanism 6 descends to the glue position. At this time, the tracking mechanism 4 drives the detection mechanism 6 to move along the extension direction of the glue for detection. When a defect is detected in the glue position, the repair end of the repair mechanism 7 extends into the glue and vibrates and repairs the bubbles and cracks in the glue, thereby ensuring the final quality of the special-shaped packaging box 13.

[0036] The shape of the special-shaped packaging box 13 in the present application is heart-shaped. In other feasible embodiments, the shape of the special-shaped packaging box 13 can also be other specific shapes. When the shape of the special-shaped packaging box 13 changes, it is only necessary to change the corresponding structure in the tracking mechanism 4.

[0037] Reference Figure 1 and Figure 2 The clamping mechanism 2 includes a clamping seat and a plurality of clamping blocks 21 arranged on the clamping seat. A space for placing the packaging box 13 is reserved between each clamping block 21. A plurality of second elastic members are arranged in the clamping seat corresponding to each clamping block 21. The second elastic members are springs. Each second elastic member is used to drive the corresponding clamping block 21 to move in a direction close to each other.

[0038] When the packaging box 13 needs to be clamped and fixed, the clamping blocks 21 are pushed apart, the packaging box 13 is placed in the space between the clamping blocks 21 , and then the clamping blocks 21 are loosened so that the clamping blocks 21 can clamp and fix the outer wall of the packaging box 13 .

[0039] Reference Figure 1 The lifting mechanism 3 includes a driving member 31, a screw rod 32 and a guide rod 33. A mounting plate 11 is provided on the detection platform 1. The tracking mechanism 4 is provided on the mounting plate 11. The driving member 31 adopts a reduction motor. The driving member 31 is provided on the detection platform 1. The screw rod 32 is coaxially fixed with the output end of the driving member 31. The screw rod 32 passes through the mounting plate 11 and is threadedly connected to the mounting plate 11. A plurality of guide rods 33 are provided. Each guide rod 33 is parallel to each other and is fixedly connected to the detection platform 1 after passing through the mounting plate 11.

[0040] When the glue in the packaging box 13 needs to be tested, the driving member 31 is controlled to work, and the driving member 31 drives the screw rod 32 to rotate, thereby realizing the lifting and lowering control of the mounting plate 11, so that the mounting frame 5 can move to the glue position.

[0041] Note that in this process, in order to prevent the mounting frame 5 from damaging the glue when it descends, it is necessary to move the mounting frame 5 in a direction away from the inner wall of the packaging box 13 so that the end of the mounting frame 5 can bypass the glue position until the middle cavity position of the mounting frame 5 is directly opposite to the glue position. The mounting frame 5 can then be released, and the tracking mechanism 4 can be started at this time, so that the detection mechanism 6 can perform quality detection on the strip of glue.

[0042] Reference Figure 1 , Figure 2 and Figure 3 The tracking mechanism 4 includes a power piece 41, a track 42, a support plate 43, a connecting rod 44, a slide seat 45 and a limit column 46. The power piece 41 adopts a servo motor. The power piece 41 is installed on the detection table 1 and is located above the packaging box 13. The track 42 can be detachably installed on the inner wall of the detection table 1, and the shape of the track 42 is consistent with the contour of the inner wall of the packaging box 13 to be detected. The support plate 43 is fixed to the end of the power piece 41 and is perpendicular to the output end of the power piece 41. The support plate 43 is provided with a slide groove along the length direction; One end of the connecting rod 44 is fixedly connected to the mounting frame 5, and two limiting columns 46 are provided. The two limiting columns 46 are spaced apart and arranged at the other end of the connecting rod 44, and the two limiting columns 46 extend to the inner and outer sides of the track 42 respectively; The slide seat 45 is slidably engaged in the slide slot and fixedly sleeved on the connecting rod 44. A first elastic member 451 is provided in the slide slot to drive the slide seat 45 to move away from the output end of the power member 41. The first elastic member 451 is a spring. The connecting rods 44 above and below the slide 45 are respectively an upper rod 441 and a lower rod 442. The ends of the upper rod 441 and the lower rod 442 are elastically and movably connected. The lower rod 442 can be displaced a certain distance along the length direction of the support plate 43, and the lower rod 442 tends to move in a direction away from the output end of the power member 41.

[0043] In the above description, when the shape of the special-shaped packaging box 13 changes, it is only necessary to change the shape of the track 42 to be consistent with the shape of the special-shaped packaging box 13 .

[0044] Reference Figure 3 and Figure 4 The detection mechanism 6 includes an ultrasonic transmitter 61 and an ultrasonic receiver 62 which are spaced apart on the mounting frame 5, and the ultrasonic transmitter 61 and the ultrasonic receiver 62 are respectively located on both sides of the glue position. The detection mechanism 6 also includes a controller which is arranged on the mounting frame 5, and the controller is electrically connected to the ultrasonic transmitter 61, the ultrasonic receiver 62, the detection mechanism 6, the tracking mechanism 4 and the repair mechanism 7 respectively.

[0045] When the mounting frame 5 moves to the glue detection position, the ultrasonic transmitter 61 emits ultrasonic waves, which pass through the glue and are received by the ultrasonic receiver 62, thereby capturing bubbles and cracks inside the glue. The controller coordinates the work of various components, collects and analyzes ultrasonic signals, and ensures high accuracy and sensitivity of detection.

[0046] In order to make the mounting frame 5 better fit with the inner wall of the special-shaped packaging box 13, a roller is embedded at the end of the mounting frame 5. During the process of moving the glue, the roller can always maintain moving fit with the inner wall of the special-shaped packaging box 13.

[0047] Reference Figure 2 , Figure 3 and Figure 4 The repair mechanism 7 includes a micro-oscillation glue repair component 71 and a dual-state hot and cold coordinated repair component 72. The micro-oscillation glue repair component 71 is used to perform vibration repair on the internal defects of the glue. The dual-state hot and cold coordinated repair component 72 is used to perform heat treatment on the surface of the glue when the micro-oscillation glue repair component 71 extends into the glue, and is used to perform cold treatment on the surface of the glue when the micro-oscillation glue repair component 71 extends out of the glue.

[0048] The micro-oscillation glue repair component 71 processes the internal defects of the glue by vibration, so that the bubbles burst, the glue is redistributed, and the sealing performance is restored. The dual-state hot and cold collaborative repair component 72 uses the hot air softening and cold air curing effects. When the repair end of the micro-oscillation glue repair component 71 enters the inside of the glue, it can heat the surface of the glue, thereby softening the surface of the glue, so that the repair end can more easily extend into the inside of the glue, and can also heat the inside of the glue to a certain extent, and achieve a better repair effect with vibration, and optimize the strength and uniformity of the glue after the glue repair.

[0049] And the surface of the glue can be briefly cooled after the repair end is pulled out of the glue, so that the temperature of the outer surface of the glue is reduced, and the fluidity of the outer surface of the glue is less than the fluidity of the inside of the glue, so that a protective layer is formed on the outer surface of the glue, and the flow protection of the internal glue is realized, and the internal glue escape is reduced, so that the shape of the repaired glue can be maintained, and the repaired glue can ensure the internal flow bonding performance while not escaping, thereby greatly improving the repair effect.

[0050] Reference Figure 4 and Figure 5The micro-oscillation glue repair component 71 includes a telescopic member 711, a repair needle 712, a vibration table 713, a vibration member 714 and a vibration transmission column 715. The telescopic member 711 adopts an electric telescopic rod. The telescopic member 711 is installed on the mounting frame 5. The repair needle 712 is arranged at the telescopic end of the telescopic member 711, and the length extension direction is colinear with the telescopic end of the telescopic member 711. The vibration table 713 is sleeved outside the repair needle 712, and a through hole is opened on the surface for the repair needle 712 to pass through. The vibration member 714 is arranged on the vibration table 713. The vibration transmission column 715 is arranged between the telescopic end of the telescopic member 711 and the repair needle 712. The diameter of the vibration transmission column 715 is larger than the diameter of the repair needle 712 and is adapted to the diameter of the through hole.

[0051] When the telescopic member 711 drives the repair needle 712 into the glue, the vibration transmission column 715 extends into the perforation of the vibration table 713. At this time, the vibration of the vibration member 714 is transmitted to the repair needle 712 through the vibration table 713 and the vibration transmission column 715, so that the repair needle 712 can perform vibration repair on defects such as bubbles and fractures inside the glue.

[0052] The vibration table 713 is installed on the detection table 1, and multiple groups of elastic support components 12 are arranged between the vibration table 713 and the detection table 1 to reduce the vibration transmitted from the vibration table 713 to the mounting frame 5. Each group of elastic support components 12 includes a multi-stage telescopic cylinder and a spring for driving the multi-stage telescopic cylinder to elastically expand and contract. One end of the multi-stage telescopic cylinder is connected to the shock absorbing table, and the other end is connected to the mounting frame 5. Multiple groups of elastic support components 12 absorb the excess energy transmitted to the mounting frame 5 by vibration, reduce the overall structural shaking caused by vibration, and extend the service life of the equipment.

[0053] Reference Figure 5 and Figure 6 The dual-state hot and cold coordinated repair component 72 includes a shaping cover 721, a rotary drum 722, a dual-state hot and cold annular cavity 723, a hot air supply bin 724, and a cold air supply bin 725. The shaping cover 721 is made of lithium aluminum silicate glass-ceramics. In other embodiments, other stable materials with low thermal conductivity, high temperature resistance, and not easy to be deformed by heating can be used. One side of the shaping cover 721 is hollow in an arc shape, and the other side is hollow in a cylindrical shape, and the arc-shaped hollow inner cavity is connected with the cylindrical hollow inner cavity. A channel for the repair needle 712 to pass through is opened in the middle of the arc-shaped and cylindrical inner cavities of the shaping cover 721, and the arc-shaped and cylindrical inner cavities of the shaping cover 721 are not connected with the channel; The arc-shaped inner side wall of the shaping cover 721 is adapted to the outer surface profile of the standard glue, and a plurality of air outlet nozzles 7211 are embedded at intervals on the arc-shaped side wall of the shaping cover 721, and the end of each air outlet nozzle 7211 is flush with the arc-shaped side wall of the shaping cover 721; The rotary cylinder 722 and the dual-state hot and cold annular cavity 723 are fixedly connected and are both slidably sleeved outside the repair needle 712. The end of the dual-state hot and cold annular cavity 723 away from the rotary cylinder 722 is rotatably connected to the cylindrical end of the shaping cover 721, and the inner cavities of the two are interconnected and the connection is rotatably sealed. A thread groove is provided on the inner wall of the rotary cylinder 722 , and an insertion rod adapted to the thread groove is provided on the outer wall of the repair needle 712 .

[0054] Reference Figure 5 and Figure 6 The hot air supply bin 724 and the cold air supply bin 725 are respectively located on both sides of the repair needle 712, and a gap is surrounded between the hot air supply bin 724 and the cold air supply bin 725 for the dual-state hot and cold ring cavity 723 to pass through, and the hot air supply bin 724 and the cold air supply bin 725 are both provided with air outlet holes, and both air outlet holes are provided with air valves that open inward in one direction, and an opening valve ball 7231 for pressing the air valve to open is provided on the outer wall of the dual-state hot and cold ring cavity 723 corresponding to the air outlet holes, and the opening valve ball 7231 is elastically foldable and arranged on the outer wall of the dual-state hot and cold ring cavity 723, and when the opening valve ball 7231 is folded, the opening valve ball 7231 is flush with the outer wall of the dual-state hot and cold ring cavity 723, and the opening valve ball 7231 is provided with an air flow hole 7232 that passes through the inside and outside of the dual-state hot and cold ring cavity 723; The diameter of the cylindrical side of the shaping cover 721 is smaller than the diameter of the dual-state hot and cold ring cavity 723 , and the diameter of the dual-state hot and cold ring cavity 723 is adapted to the gap between the hot air supply chamber 724 and the cold air supply chamber 725 .

[0055] When the retractable member 711 drives the repair needle 712 to be inserted into the glue, the end of the plastic cover 721 first abuts against the inner wall of the packaging box 13, and the plastic cover 721 fits with the outer wall of the glue. At this time, the dual-state hot and cold annular cavity 723 is inserted into the gap between the hot air supply chamber 724 and the cold air supply chamber 725; Then the telescopic member 711 continues to drive the repair needle 712 to move and insert it into the glue. At this time, the insertion rod on the repair needle 712 drives the rotary cylinder 722 to rotate, and the rotary cylinder 722 drives the dual-state hot and cold ring cavity 723 to rotate. The valve opening ball 7231 on the dual-state hot and cold ring cavity 723 rotates to face the air outlet on the hot air supply bin 724. At this time, the valve opening ball 7231 opens the air valve, and the hot air in the hot air supply bin 724 enters the inner cavity of the shaping cover 721 and is finally ejected from the air outlet nozzle 7211, thereby heating the glue surface, so that the repair needle 712 can better repair the defective part. When the repair is completed, the telescopic part 711 drives the repair needle 712 to be pulled out of the glue. During this process, the insertion rod first drives the rotary cylinder 722 to rotate, and the rotary cylinder 722 drives the dual-state hot and cold ring cavity 723 to rotate, so that the valve opening ball 7231 rotates to be opposite to the air outlet of the cold air supply bin 725. At this time, the valve opening ball 7231 opens the air valve on the cold air supply bin 725, allowing cold air to enter the plastic cover 721, thereby briefly spraying cold air on the outer surface of the repaired glue, so that the adhesion performance of the glue inside is guaranteed while reducing the stickiness of the outer surface, and also ensuring the escape protection of the internal repaired glue, so that the quality of the repaired glue is better.

[0056] The implementation principle of a packaging box dispensing detection device in the embodiment of the present application is as follows: the micro-oscillation glue repair component 71 processes the internal defects of the glue through vibration, so that the bubbles burst, the glue is redistributed, and the sealing performance is restored. The dual-state hot and cold collaborative repair component 72 uses the effects of hot air softening and cold air curing. In the process of the repair end of the micro-oscillation glue repair component 71 entering the interior of the glue, the surface of the glue can be heated, thereby softening the surface of the glue, so that the repair end can more easily extend into the interior of the glue, and the interior of the glue can also be heated to a certain extent, and a better repair effect can be achieved with vibration, and the strength and uniformity of the glue after the glue repair are optimized.

[0057] And the surface of the glue can be briefly cooled after the repair end is pulled out of the glue, so that the temperature of the outer surface of the glue is reduced, and the fluidity of the outer surface of the glue is less than the fluidity of the inside of the glue, so that a protective layer is formed on the outer surface of the glue, and the flow protection of the internal glue is realized, and the internal glue escape is reduced, so that the shape of the repaired glue can be maintained, and the repaired glue can ensure the internal flow bonding performance while not escaping, thereby greatly improving the repair effect.

[0058] The present application also discloses a packaging box glue dispensing detection method, which is applied to the packaging box glue dispensing detection device, and includes the following steps: S1: Push aside the clamping blocks 21, place the packaging box 13 in the space between the clamping blocks 21, and then loosen the clamping blocks 21 so that the clamping blocks 21 clamp and fix the outer wall of the packaging box 13; S2: Control the lifting mechanism 3 to descend, so that the mounting frame 5 moves toward the glue position in the packaging box 13. When the end of the mounting frame 5 moves to the upper end of the packaging box 13, the lower rod 442 is moved toward the output end of the power member 41, so that the end of the mounting frame 5 bypasses the glue position until the middle cavity position of the mounting frame 5 is aligned with the glue position, and the lower rod 442 can be released. S3: Start the power member 41, so that the power member 41 drives the mounting frame 5 to move along the inner wall of the packaging box 13. At this time, the detection mechanism 6 performs ultrasonic quality detection on the inside of the glue. When it is detected that there is a defect in the glue position, the telescopic member 711 drives the detection needle to extend into the glue. At this time, the vibration member 714 transmits the vibration to the detection needle, so that the detection target performs vibration repair on the defective part, and the shaping cover 721 is connected with the hot air supply bin 724, and the air outlet nozzle 7211 sprays hot air on the surface of the glue; S4: After a short vibration repair, the telescopic part 711 drives the detection needle to be pulled out from the inside of the glue. When the detection needle is completely pulled out from the inside of the glue, the vibration part 714 no longer vibrates. At this time, the shaping cover 721 is connected with the cold air supply bin 725, and the air outlet nozzle 7211 sprays cold air to the surface of the glue, thereby completing the repair of the inside of the glue and the protection of the outer surface of the glue from glue leakage.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
