Abstract
Description
Technical Field
[0001] The present application relates to the technical field of defect inspection equipment, and in particular to a device for periodic defect inspection of finished product rolls. Background Art
[0002] Visual inspection of finished polyester film rolls is the final step before packaging. For mid- to high-end films with stringent appearance requirements, periodic inspections are crucial. Periodic defects are often small and sparse, exhibiting a stable, periodic distribution longitudinally and covering a wide area, significantly impacting the film's appearance quality. Treating periodic defects as merely ordinary defects not only fails to accurately assess their impact on the entire roll, but also increases customer complaints once defective rolls are shipped, impacting the company's overall quality reputation. Existing equipment for periodic defect inspection of finished rolls presents two extremes. High-end equipment is fully equipped to handle a wide range of defects and boasts a high degree of automation. However, its high cost prohibits many manufacturers, and its bulky design makes it difficult to fit into relatively narrow darkrooms. Lower-end equipment, however, is overly simplistic, using only a horizontal bar and a few light tubes to construct an inspection platform. This ineffective inspection process also makes it impossible to locate periodic defects through retrospective review. Utility Model Content

[0035] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0036] The embodiment of the present application provides a finished product roll periodic defect inspection device, which is installed in a darkroom and is used to inspect the periodic defects of the finished polyester film roll. Figure 1 As shown, the finished roll periodic defect inspection equipment includes: a first clamper group 1, the first clamper group 1 is used to clamp the polyester film finished roll; a second clamper group 2, the second clamper group 2 is used to clamp the paper tube and pull the polyester film to move so that the polyester film is wrapped around the paper tube; a xenon lamp 3, the xenon lamp 3 is used to irradiate the polyester film so that the operator can observe the periodic defects of the polyester film.
[0037] like Figure 2 As shown, in some embodiments, the first clamper group 1 and the second clamper group 2 each include two clampers 4; the clamper 4 includes: a retractable support 41, the retractable support 41 is used to adjust the height of the clamper 4; a steel core 42, the steel core 42 is connected to the top of the retractable support 41, and is used to clamp the polyester film finished roll or paper tube; a rotary wrench 43, the rotary wrench 43 is connected to the top of the retractable support 41, and is used to drive the steel core 42 to rotate.
[0038] like Figure 2 As shown, in some embodiments, the steel core 42 includes a first steel core 421 and a second steel core 422 , and the diameter of the first steel core 421 is smaller than the diameter of the second steel core 422 .
[0039] like Figure 2 As shown, in some embodiments, the clamp 4 also includes: a fixing hole 44, which is arranged on the retractable pillar 41 and is used to fix the height of the retractable pillar 41; and a movable roller 45, which is connected to the bottom end of the retractable pillar 41 and is used to adjust the width between the two clamps 4.
[0040] In some embodiments, the height difference and the spacing distance between the first gripper group 1 and the second gripper group 2 are equal.
[0041] In some embodiments, the xenon lamp 3 is installed on the top of the darkroom.
[0042] In some embodiments, the angle between the light of the xenon lamp 3 and the polyester film is 45°.
[0043] like Figure 1 As shown, in some embodiments, the finished roll periodic defect inspection equipment further includes: an observation table 5, wherein the observation table 5 is located between the first clamper group 1 and the second clamper group 2, and is used for the operator to observe the periodic defects of the polyester film.
[0044] In practice, the finished roll periodic defect inspection equipment primarily consists of a first gripper assembly, a second gripper assembly, a xenon lamp, and an observation table. This equipment is installed in a darkroom and can be freely arranged to suit the room's size.
[0045] The clamp is connected by a retractable support, a fixed hole, a first steel core, a second steel core, and a movable roller. The retractable support can adjust the height of the clamp, the fixed hole can fix the adjusted height, the first steel core and the second steel core can fix 3-inch and 6-inch paper tubes respectively, and the movable roller can be flexibly adjusted according to the width of the paper tube.
[0046] The two sets of clamps respectively clamp the finished polyester film roll and the paper tube. The height difference and spacing between the two sets of clamps are kept consistent, so that the light of the xenon lamp can be irradiated on the film at 45 degrees. The steel core is rotated by the rotating wrench, so that the film on the paper tube can be moved in a certain direction. The xenon lamp is installed on the top of the darkroom, and the light is irradiated on the film at 45 degrees, which is projected onto the observation table. The operator can observe the status of the film on the observation table.
[0047] Use a trolley to transport the polyester film finished roll sample to be tested to the darkroom, adjust the height and width of the first clamp group to be consistent with the height and width of the paper tube on the sample, fix the sample paper tube on the first clamp group, adjust the height and width of the second clamp group according to the height and width of the second clamp group, so that the film movement direction and the xenon lamp irradiation direction form a 45° angle, install the same specification paper tube on the second clamp group, stick tape on it, and pull the sample film onto the paper tube on the second clamp group.
[0048] After gluing, turn on the xenon lamp and turn off the lighting. One person uses a rotary wrench to rotate the steel core on the second clamping group, so that the film moves toward the paper tube clamped by the second clamping group and is wrapped around the paper tube. Figure 3As shown. One person stands in front of the observation table, observes the film, and marks defects on the film with a marker. After observing one side, the reel direction can be adjusted to observe the other side of the film.
[0049] The finished roll periodic defect inspection equipment provided in this application cleverly connects a xenon lamp, a rewinding stand, an unwinding stand, an observation platform, and other equipment in a darkroom to form a simplified, fully functional, periodic defect inspection system for finished rolls. This equipment not only allows for flexible adjustment in the darkroom environment but also fully detects periodic and other defects. This reduces costs, increases device penetration, and increases the probability of defect detection, thus minimizing losses for companies.
