Description

Technical Field

[0002] Reflective film is widely used in traffic signs, vehicle license plates, billboards, etc. Its quality directly affects nighttime driving safety and visual effects. However, in the production of reflective film, it is necessary to perform defect detection on the reflective film to ensure whether the produced reflective film is qualified. However, the existing reflective film defect detection method still has some defects. For example, the traditional reflective film defect detection mainly relies on artificial vision, but the detection by artificial vision is not only inefficient but also subject to subjective influence, and the qualified rate of the detection cannot be guaranteed. For example, the reflective film defect detection device in the publication number: CN219573948U, when the device is running, only the reflective film surface is compared and detected, and the defective position is marked and an alarm is issued. When the reflective film is compared, it is impossible to identify whether the surface defect of the reflective film is a stain or offset printing, and the mark and alarm are directly performed, which affects the efficiency of the reflective film defect detection, and after the alarm, the defective position still needs to be manually cut, and after cutting, it needs to be manually aligned before continuing the detection, and the automation is low, which cannot meet the problem of high efficiency of the factory.

[0013] Compared with the existing technology, the advantages of this reflective film defect detection device are:

[0014] 1. The present invention cooperates with an ultraviolet detection plate 1 and a scraper. When detecting defects of a reflective film, the ultraviolet detection plate 1 irradiates ultraviolet rays toward the reflective film, so that the reflective film refracts the ultraviolet rays irradiated by the ultraviolet detection plate 1. When the ultraviolet detection plate 1 does not receive the refracted ultraviolet rays, the scraper moves toward the reflective film and scrapes the surface of the reflective film to clean the stains and offset printing on the surface of the reflective film.

[0015] 2. The present invention cooperates with the upper cutter and the lower cutter to drive the upper cutter and the lower cutter to cut the reflective film when detecting defects of the reflective film through the second ultraviolet detection board. When the second ultraviolet detection board does not receive the refracted ultraviolet rays, the upper cutter cuts the reflective film to separate the defective part and the qualified part of the reflective film. When the second ultraviolet detection board receives the refracted ultraviolet rays again, the lower cutter cuts the reflective film again to separate the defective part of the reflective film and discharge it to the waste material outlet. The cutting of the reflective film by the upper cutter and the lower cutter solves the problem that the defective position still needs to be cut manually after the alarm, the automation is low, and the high-efficiency work of the factory cannot be met.

[0016] 3. The present invention cooperates with the upper cutter and the winding roller. When the reflective film defect detection is performed, when the ultraviolet detection plate 2 does not receive the refracted ultraviolet rays, the upper cutter moves and cuts the reflective film. After the upper cutter moves, the winding roller stops rotating. When the ultraviolet detection plate 2 receives the refracted ultraviolet rays again, the lower cutter shears the reflective film and pushes the upper cutter back to its position. When the upper cutter moves and returns to its position, the reflective film is continuously transported, so that the transported reflective film and the wound reflective film are in contact. After the contact, the upper cutter returns to its position. After the upper cutter returns to its position, the winding roller continues to rotate for winding. The winding roller is driven to rotate and stop by the upper cutter, which solves the problem that manual alignment is required after cutting before continuing the detection, the automation is low, and the high-efficiency work of the factory cannot be met.

[0037] Among them, the working principles of the upper cutter 43 and the lower cutter 44 are as follows: after the ultraviolet detection plate 22 is started, the ultraviolet detection plate 22 irradiates ultraviolet rays to the reflective film, and the irradiated ultraviolet rays are refracted to the side wall of the ultraviolet detection plate 22 through the reflective film. When the irradiated ultraviolet rays are not refracted to the side wall of the ultraviolet detection plate 22, the drive motor 3 412 is started and rotated forward, the large intermittent gear 41 and the rack 3 431 are meshed with each other, and the upper cutter 43 moves downward and shears the reflective film. When the upper cutter 43 moves to the bottom, the drive motor 3 412 is turned off. When the irradiated ultraviolet rays continue to be refracted to the side wall of the ultraviolet detection plate 22, the drive motor 3 412 is started and rotated forward, the large intermittent gear 41 and the rack 4 441 are meshed with each other, the lower cutter 44 moves upward and shears the reflective film, and when the lower cutter 44 moves to the top, the drive motor 3 412 is turned off.

[0038] like Figure 6-Figure 8As shown, the lower cutter 44 is slidably installed in the waste port 14, the side wall of the upper cutter 43 is integrally formed with a pressure plate 2 435, and the side wall of the pressure plate 2 435 is slidably installed with a pressure plate 1 42, the side wall of the upper cutter 43 is provided with a slide groove 1 434, the side wall of the pressure plate 1 42 is integrally formed with a slide bar 1 423, and the slide bar 1 423 is slidably installed in the slide groove 1 434, a plurality of springs 1 422 are provided between the top of the pressure plate 2 435 and the side wall of the upper cutter 43, the side wall of the pressure plate 1 42 is provided with a rack 2 421, and the side wall of the large intermittent gear 41 is integrally formed with a small intermittent gear 411, and the small intermittent gear 411 and the rack 2 421 are meshed.

[0039] Among them, the working principles of the pressing plate 1 42 and the pressing plate 2 435 are as follows: when the upper cutter 43 moves downward and shears the reflective film, the pressing plate 2 435 moves downward with the upper cutter 43; when the shearing is completed, the upper cutter 43 continues to move downward to the bottom, and the bottom of the pressing plate 2 435 guides the reflective film downward so that the reflective film is transported to the waste outlet 14; when the large intermittent gear 41 and the rack 441 are meshed with each other, the small intermittent gear 411 and the rack 2 421 are meshed with each other, the lower cutter 44 moves upward, and the pressing plate 1 42 moves upward, and the reflective film is sheared through the side walls of the lower cutter 44 and the pressing plate 1 42; when the shearing is completed, the pressing plate 1 42 moves along the slide groove 1 434 through the spring 1 422 and returns to its position; the top of the lower cutter 44 is higher than the detection table 1, so that when the reflective film moves, the lower cutter 44 lifts up the reflective film to prevent the reflective film from being transported to the waste outlet 14.

[0040] like Figure 6-Figure 9 As shown, the side wall of the upper cutter 43 is integrally formed with a push rod 432, and the push rod 432 contacts the side wall of the lower cutter 44. The side wall of the rack three 431 is fixedly installed with a motor compartment 433 by screws. A driving motor four 451 is fixedly installed in the motor compartment 433. The output shaft of the driving motor four 451 is fixedly connected with a gear six 45. The gear six 45 is rotatably mounted on the outer side of the motor compartment 433, and the gear six 45 and the gear seven 452 are meshed.

[0041] Among them, the working principle of the push rod 432 is: when the upper cutter 43 moves downward, the lower cutter 44 moves downward with the upper cutter 43 through the resistance of the push rod 432, and when the lower cutter 44 moves upward, the upper cutter 43 moves upward with the lower cutter 44 through the push rod 432, and when the lower cutter 44 moves upward to the top, gear six 45 and gear seven 452 engage with each other.

[0042] like Figure 3 and Figure 10-12As shown, a winding roller 52 is movably installed on the side wall of the detection platform 1, and a slide groove 2 171 and a slide groove 3 172 are opened on the side wall of the detection platform 1, a sliding sleeve 1 531 is slidably installed in the slide groove 2 171, and a fixed rod 524 is rotatably installed in the sliding sleeve 1 531, and the winding roller 52 and the fixed rod 524 are fixed by threads, and the side wall of the winding roller 52 is fixedly sleeved with a winding drum 521, and the side walls of the winding roller 52 and the fixed rod 524 are fixedly sleeved with a fixing ring 533, and the side wall of the fixing ring 533 is rotatably installed with evenly distributed clamping jaws 1 535, and the side wall of the clamping jaw 1 535 is rotatably installed with clamping jaws 2 534, and torsion springs are provided at the installation locations of the fixing ring 533 and the clamping jaw 1 535, and torsion springs are provided at the installation locations of the clamping jaw 1 535 and the clamping jaw 2 534, and a shifting rod 16 is provided on the side wall of the detection platform 1, and the shifting rod 16 is located on the side wall of the winding drum 521.

[0043] The working principle of the clamping jaw 1 535 and the clamping jaw 2 534 is as follows: in the initial state, the clamping jaw 1 535 and the clamping jaw 2 534 are straight rods and fit together with the side wall of the winding drum 521. When the winding drum 52 drives the fixing rod 524 to rotate and rewind, the fixing ring 533 drives the clamping jaw 1 535 and the clamping jaw 2 534 to rotate along with the winding drum 52. The top of the lever 16 contacts the side wall of the clamping jaw 1 535, so that the clamping jaw 1 535 drives the clamping jaw 2 534 to tilt upward away from the winding drum 521. When the side wall of the clamping jaw 2 534 contacts the side wall of the detection platform 1, the clamping jaw 1 535 and the clamping jaw 2 534 are tilted upward away from the winding drum 521. After the wall is reached, the jaws 1 535 and the jaws 2 534 are bent at their installation locations. When the jaws 2 534 are away from the side wall of the testing platform 1, the jaws 1 535 and the jaws 2 534 are twisted into a straight rod shape by the torsion springs at their installation locations. The jaws 1 535 are twisted by the torsion springs at their installation locations with the fixing ring 533 and continue to fit the side wall of the winding drum 521. When the winding is completed, the winding roller 52 and the fixing rod 524 are twisted through opposite rotations to separate the winding roller 52 and the fixing rod 524. The winding drum 521 is taken out and placed on the placement platform 13.

[0044] like Figure 5 , Fig.10 , Fig.12 and Fig.13As shown, the side wall of the winding roller 52 is integrally formed with a pulley six 522, a sleeve two 541 is slidably installed in the slide groove three 172, a small pulley 54 is rotatably installed in the sleeve two 541, a pulley four 262 is fixedly installed on the side wall of the gear four 261 by screws, a belt four 523 is arranged between the pulley six 522, the small pulley 54 and the pulley four 262, an extrusion roller 51 is rotatably installed on the side wall of the inspection platform 1, a pulley five 511 is integrally formed on the side wall of the extrusion roller 51, a pulley three 253 is integrally formed on the side wall of the pulley two 252, a belt three 512 is arranged between the pulley five 511 and the pulley three 253, a spring platform one 151 and a spring platform two 152 are integrally formed on the side wall of the inspection platform 1, a spring two 532 is arranged between the spring platform one 151 and the sleeve one 531, and a spring three 542 is arranged between the sleeve two 541 and the spring platform two 152.

[0045] Among them, the working principle of the winding roller 52 is: when the winding roller 52 continues to rotate for winding, as the amount of reflective film wound increases, the diameter of the winding drum 521 increases, and the squeezing roller 51 continuously squeezes the winding roller 52, so that the winding roller 52 drives the sliding sleeve 1 531 to slide along the sliding groove 2 171, and the small pulley 54 drives the sliding sleeve 2 541 to slide along the sliding groove 3 172. When the winding drum 521 is taken out, the sliding sleeve 1 531 and the sliding sleeve 2 541 return to their positions through the spring 2 532 and the spring 3 542 respectively.

[0046] The specific working principle and use method of the present invention are explained in detail below: after starting the driving motor 1 27 and the driving motor 4 451, the ultraviolet detection plate 1 21 and the ultraviolet detection plate 2 22 are started for detection. When the ultraviolet detection plate 1 21 does not receive the ultraviolet rays refracted by the reflective film, the driving motor 2 311 is started and rotated forward, and the scraper 32 drives the rubber strip 33 to move to the surface of the reflective film to scrape off the stains and residual offset printing on the surface of the reflective film. When the ultraviolet detection plate 1 21 continues to receive the ultraviolet rays refracted by the reflective film, the driving motor 2 311 is started and reversed, and the scraper 32 drives the rubber strip 33 to return to its position. When the ultraviolet detection plate 22 continues to receive the ultraviolet rays refracted by the reflective film, the gear 6 45 and the gear 7 are rotated forward. 452 are meshed with each other, and the pulley six 522 drives the winding roller 52 to rotate and rewind.
