Description

Technical Field

[0001] The invention relates to the technical field of gluing quality detection, and in particular to a device and method for detecting the gluing quality of cigarette box paper. Background Art

[0002] Gluing is a process, also known as gluing, coating, filling, dripping, etc. It is to apply, fill, and drip electronic glue, oil, or other liquids onto products to make the products stick, fill, insulate, fix, and smooth the surface. In industrial production, after gluing the glued parts, it is generally necessary to use CCD equipment to check the glued parts to ensure the quality of the glue. At present, after UV gluing, it is generally necessary to remove the glued parts on the glue dispensing machine and place them on the base of CCD detection for glue quality inspection. This will cause the action of picking up between the gluing and quality inspection processes, which not only increases the workload of the operator but also reduces production efficiency.

[0003] The Chinese patent application number CN202310744900.6 discloses a gluing quality detection device and working method for cigarette boxes based on image detection. The cigarette boxes are transported through the cigarette box conveying track, and the cigarette boxes to be pasted are released through the box release mechanism. The lining paper release mechanism is set on the side of the cigarette box conveying track to release the lining paper; and the gluing detection mechanism is suitable for grabbing the lining paper and pasting the lining paper on the cigarette box to be pasted, so that the gluing detection mechanism is suitable for applying hot melt glue on the cigarette box while grabbing the lining paper, and then taking photos to collect the gluing quality information. After determining that the gluing quality is qualified, the lining paper is pasted, and the lining paper is compacted after the pasting is completed, which solves the problem that the existing cigarette box lining paper cannot accurately control the amount of glue when pasting, and the lining paper has warping after pasting. However, the patent detection equipment is fixed-point detection, and cannot detect the gluing quality problem from multiple angles. The comprehensiveness of the detection is not strong, and the detection efficiency is not high, which affects the accuracy of the detection.

[0004] In order to increase the sealing effect of the light shield, an electric push rod is used to push the gate to seal the light shield, thereby reducing the brightness inside the light shield. However, this setting not only introduces a new power source, but also requires the writing of complex programs to make the electric push rod continuously contract. As a result, the travel switch on the push rod may be worn, causing the push rod to be unable to accurately stop at the predetermined position, thereby affecting the accuracy and reliability of the equipment. The detection equipment performs fixed-point detection and cannot detect glue quality problems from multiple angles. The detection is not comprehensive, and the detection efficiency is not high, affecting the accuracy of the detection.

[0026] Start the drive motor 12, the drive motor 12 drives the crank 13 to rotate, and the crank 13 drives the pulley 15 to rotate in the sliding groove 25, so that the pulley 15 drives the adjusting member 14 to reciprocate in the longitudinal direction of the movable plate 7 through the sliding groove 25, so that the adjusting member 14 drives the movable plate 7 to reciprocate through the connecting block 16 and the connecting rod 17.

[0027] like Figure 3 - Figure 8 As shown, in order to realize automatic opening and closing of the two shielding plates 10 when the movable plate 7 reciprocates, a transmission assembly is arranged in the detection box 5, and the shielding plate 10 for sealing is slidably connected to the outside of the detection box 5, and the transmission assembly is used for lifting and lowering the shielding plate 10, and the transmission assembly includes a lead screw 20 rotatably connected between the top wall and the bottom wall of the detection box 5, and the outer wall of the lead screw 20 is rotatably connected with a connecting arm 21 and is connected and fixed to one side of the shielding plate 10, and the lead screw 20 is threadedly connected to the connecting arm 21, and the connecting arm 21 close to the side of the mounting frame 2 is initially located at the bottom of the lead screw 20, so that the shielding plate 10 is in a closed state, and the connecting arm 21 away from the side of the mounting frame 2 is initially located at the top of the lead screw 20, so that the shielding plate 10 is in an open state. The purpose of such a setting is that when the movable plate 7 drives the storage seat 8 to move toward the connecting arm 21 away from the side of the mounting frame 2, the shielding plate 10 gradually descends, and when the storage seat 8 moves to the inside of the detection box 5, the shielding plate 10 can be completely closed. Close, seal the storage seat 8 into the detection box 5 for detection, the connecting arm 21 is initially located in the middle of the screw 20, the connecting arm 21 moves downward to drive the baffle plate 10 to close the detection box 5, and the connecting arm 21 moves upward to drive the baffle plate 10 to open the detection box 5, the bottom end of the screw 20 is fixedly connected with a transmission gear 19, and the longitudinal sides of the movable plate 7 are fixedly connected with toothed plates 18. There are two transmission components, and the two transmission components are respectively located in the two detection boxes 5, the two transmission gears 19 are respectively arranged on both sides of the movable plate 7, and the two transmission gears 19 are obliquely symmetrically arranged, and the longitudinal sides of the movable plate 7 are fixedly connected with toothed plates 18, the two toothed plates 18 are respectively meshed with the two transmission gears 19, so that the two transmission gears 19 rotate forward and backward respectively, and the two toothed plates 18 are respectively meshed with the two transmission gears 19, so that the two transmission gears 19 rotate forward and backward respectively, so that the two baffle plates 10 can achieve the effect of automatic sealing and automatic opening, and the opening and closing of the two detection boxes 5 are realized.

[0028] When the movable plate 7 moves back and forth, the movable plate 7 drives the tooth plates 18 on both sides to move synchronously. The movement of the two tooth plates 18 drives the two transmission gears 19 to rotate respectively, so that the two transmission gears 19 rotate forward and reverse respectively, thereby making the transmission gear 19 drive the lead screw 20 to rotate, and the lead screw 20 drives the baffle plate 10 located on the outer wall of the detection box 5 to move back and forth through the connecting arm 21, so as to achieve the effect that the two baffle plates 10 automatically seal downward and automatically open upward, and this alternating cycle is realized.

[0031] When in use, firstly, the dispensing head on the automatic dispensing machine 3 can be used to perform UV dispensing on the dispensing parts of the storage seat 8. The dispensing head is set to dispense glue on one of the dispensing parts first, and the transmission cooperation of the driving motor 12, the crank 13, and the adjusting part 14 is used to make the movable plate 7 reciprocate, and the dispensing part after dispensing extends into one of the detection boxes 5. The transmission cooperation of the tooth plate 18 and the transmission gear 19 is used to make the two shielding plates 10 able to achieve the effect of automatic sealing and automatic opening according to the movement of the two storage seats 8. The storage seat 8 moved to the detection box 5 is under the action of the ultraviolet light, so that the dispensing area on the dispensing part is clearly presented, and then the CCD camera 6 on the same side is used to collect images of the dispensing place and transmit the information to the display screen 4 on the same side. Then the staff can determine the dispensing quality by observing the enlarged image on the display screen 4, and distinguish whether the glue is good or bad. If the dispensing is good, the ultraviolet light continues to irradiate the UV glue on the dispensing part and accelerate the curing of the UV glue. During the UV glue curing process, the other storage seat 8 will be moved out of the inspection box 5 through the reciprocating motion of the moving plate 7 and the glue dispensing head will be used to dispense glue to the glued parts, so that UV glue dispensing and UV glue curing are carried out simultaneously; if the glue dispensing quality detection is defective, the moving plate 7 is operated to move in the opposite direction so that the two shielding plates 10 are opened and closed respectively, and then the defective glued parts can be taken out, and the other storage seat 8 after glue dispensing is extended to another inspection box 5 for detection, and the glue dispensing head on the automatic glue dispensing machine 3 can perform UV glue dispensing on the glued parts of one of the storage seats 8, and the other storage seat 8 after glue dispensing is extended to another inspection box 5 for detection, and such alternating cycle can omit the action of taking and turning around in the middle, thereby improving the detection work efficiency, and the operation is convenient and simple, and the glue dispensing and curing operations of the two glued parts can be realized without connecting multiple drive sources, and the UV glue dispensing and UV glue curing are carried out simultaneously through the rotation and use of the transmission component and the adjustment component, which greatly improves the detection efficiency.

[0032] Embodiment 2 Based on the above embodiments, the detection equipment performs fixed-point detection and cannot detect glue coating quality problems from multiple angles. The detection is not comprehensive and the detection efficiency is not high, which affects the accuracy of the detection.

[0033] like Figure 3 , Figures 9 to 12As shown, a deflection assembly is arranged inside the detection box 5 and is used for angular deflection of the storage seat 8. There are two deflection assemblies, and the two transmission assemblies are respectively located in the two detection boxes 5. The deflection assembly includes a fixed column 27, and the bottom of the fixed column 27 is fixedly connected to the bottom wall of the detection box 5. The fixed column 27 and the transmission gear 19 of the deflection assembly on the same side are respectively located on both sides of the movable plate 7. The top of the fixed column 27 is fixedly connected to a limit rod 28. The limit rod 28 is fixed by the fixed column 27 to prevent the limit rod 28 from displacement. One end of the limit rod 28 is fixedly connected to the inner wall of the detection box 5, and the other end of the limit rod 28 is rotatably connected with a rotating bead 30. The storage seat 8 is located on both longitudinal sides of the movable plate 7 and limit grooves are provided. The limit groove 31 is shaped like a trumpet as a whole, that is, the bottom diameter of the limit groove 31 is larger than the diameter of the groove mouth, so that the rotating ball 30 cannot be separated from the limit groove 31 when moving in the limit groove 31, and the depth of the limit groove 31 can be adjusted as the rotating ball 30 rotates, and the openings on both sides of the limit groove 31 are located in the middle of the height direction of the storage seat 8, and the height of the limit rod 28 is parallel to the position of the openings on both sides of the limit groove 31. The limit groove 31 is arranged in a wave shape, and the wave has a highest point and a lowest point. The length direction of the limit rod 28 is perpendicular to the opening of the limit groove 31, and then during the movement of the storage seat 8, the limit groove 31 opened on the storage seat 8 can contact and slide with the rotating ball 30 under the limitation of the limit rod 28.

[0034] When the moving plate 7 moves, the storage seat 8 is driven to move. When the storage seat 8 moves to the deflection assembly, the opening of the limit groove 31 contacts the rotating bead 30. The limit groove 31 deflects along the rotating bead 30 under the limit of the rotating bead 30. The wave of the limit groove 31 has a highest point and a lowest point. Fig. 9 As shown, when the highest point of the limiting groove 31 contacts the rotating ball 30, the storage seat 8 deflects toward the limiting rod 28 and squeezes the elastic member 29; Fig.10 As shown, when the lowest point of the limiting groove 31 contacts the rotating bead 30, the storage seat 8 deflects in the direction away from the limiting rod 28 and stretches the elastic member 29; thereby realizing the automatic deflection of the storage seat 8 angle. During the deflection process, the storage seat 8 clearly reflects whether there are foreign matter bumps, broken glue, overflowing glue, bubbles, lack of glue and other problems inside the glue spot. The CCD camera 6 performs multi-angle image acquisition on the glue spot on the storage seat 8 and transmits the information to the display screen 4 on the same side. The CCD camera 6 fixed-point detection can also realize multi-angle detection, saving multiple CCD cameras 6. At the same time, one CCD camera 6 is not prone to error detection, thereby improving the detection efficiency, improving the comprehensiveness of the detection, and ensuring the accuracy of the detection. When the glue spot on the storage seat 8 is detected and moved out of the detection box 5, the storage seat 8 is reset under the elastic action of the elastic member 29, which is convenient for the next cigarette box paper to be glued, thereby improving the detection efficiency.

[0035] Through the cooperation between the limit rod 28, the rotating bead 30 and the limit groove 31, the highest point and the lowest point of the limit groove 31 are in contact with the rotating bead 30 respectively, so as to realize the multi-angle detection of the deflection glue spot of the storage seat 8. During the deflection process, the storage seat 8 can clearly reflect whether there are foreign objects, protruding points, broken glue, overflowing glue, bubbles, lack of glue and other problems inside the glue spot. The CCD camera 6 collects multi-angle images of the glue spot on the storage seat 8 and transmits the information to the display screen 4 on the same side, so as to improve the detection efficiency, improve the comprehensiveness of the detection and ensure the accuracy of the detection.

[0036] Embodiment 3 Based on the above embodiments, the present invention provides a method for detecting the gluing quality of cigarette box paper, comprising the following steps: S1: UV glue can be applied to the glued parts of the storage seat 8 by the glue dispensing head on the automatic glue dispensing machine 3. The glue dispensing head is set to dispense glue to one of the glued parts first. After the glue dispensing is completed, the movable plate 7 is reciprocated by the transmission cooperation of the driving motor 12, the crank 13, and the adjusting member 14. The glued parts after glue dispensing extend into one of the detection boxes 5. The transmission cooperation of the tooth plate 18 and the transmission gear 19 is utilized. Since the tooth plate 18 is respectively engaged with the two transmission gears 19, the two transmission gears 19 rotate forward and reverse respectively. The two shielding plates 10 can achieve the effect of automatic sealing and automatic opening according to the movement of the two storage seats 8.

[0037] S2: The storage seat 8 moves, and the highest and lowest points of the limit groove 31 contact the rotating bead 30 respectively, so as to realize the multi-angle detection of the deflection dispensing of the storage seat 8. The storage seat 8 moved into the detection box 5 makes the dispensing area on the dispensing part clearly presented under the action of the ultraviolet light.

[0038] S3: Then, the CCD camera 6 is used to collect images of the glue dispensing area and transmit the information to one of the display screens 4. Then, the staff can determine the quality of the glue dispensing by observing the enlarged image on the display screen 4. At this time, if the glue dispensing is good, the UV light continues to irradiate the UV glue on the glued part and accelerate the curing of the UV glue. During the UV glue curing process, another storage seat 8 will be moved out of the inspection box 5 through the reciprocating motion of the moving plate 7 and can dispense glue to the glued part through the glue dispensing head, so that UV glue dispensing and UV glue curing are carried out simultaneously.

[0039] S4: If the glue dispensing quality detection is defective, the driving motor 12 is operated to move the movable plate 7 in the relative direction, so that the two shielding plates 10 are opened and closed respectively, and then the defective glue dispensing parts can be taken out, and the other storage seat 8 after glue dispensing is extended to another inspection box 5 for inspection, and the alternating cycle can be omitted.
