Description

Technical Field

[0001] The utility model relates to the technical field of protective film crystal point detection equipment, in particular to a crystal point detection device for a non-crystal point PET protective film. Background Art

[0002] The crystal point detection of protective film is usually carried out using an online crystal point tester for thin films. This tester realizes automatic control of the light source, optical system and detector through precise control algorithms. The detector uses a highly sensitive photoelectric detector to capture the image signal of the surface of the film being tested in real time. Then, the data processing system processes the collected image signal and calculates the coordinates and number of crystal points. In the prior art, the detection of protective film requires the transmission of the protective film, but lacks the limit guide function for the transmission of the protective film, which makes the protective film easy to deviate during the transmission process, affecting its winding effect.

[0003] For example, an authorized patent document with application number CN202321135058.8 discloses a membrane switch button tester, which includes a base, a cylinder is arranged inside the base, the output end of the cylinder is fixedly connected to a cross bar, the two ends of the cross bar are respectively fixedly connected to support rods, and the support rods pass through the upper side wall of the base, and is characterized in that a pressing assembly is arranged between the two support rods, and the pressing assembly includes a lifting frame and multiple groups of pressing mechanisms; the lifting frame is arranged as a rectangular structure, the two ends are respectively connected to the support rods, and the two long side walls are provided with sliding grooves; the length of the limiting plate of the utility model is greater than the diameter of the pressing rod and the length of the slider, which provides convenience for adjusting the positions of multiple pressing rods so that they are not on the same straight line, and provides convenience for simultaneously testing the buttons of membrane switches of multiple sizes, thereby enhancing the practicality of the device.

[0004] The above patent lacks the function of limiting and guiding the transmission of the protective film, which causes the protective film to be easily offset during the transmission process, affecting its winding effect. Therefore, we need to provide a crystal point detection device for crystal-free PET protective film. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-4A crystal point detection device for a crystal point-free PET protective film comprises: an operating table 1, and a support plate 2 fixedly mounted on the top of the operating table 1; a gantry 3 fixedly mounted on the top of the support plate 2, a crystal point detector 5 is installed inside the gantry 3 through an adjusting member 4; a plurality of guide rotating rollers 6 rotatably mounted on one side of the support plate 2; a guide mechanism 7 for limiting the conveyance of the protective film is arranged on the top of the operating table 1, the guide mechanism 7 comprises a groove body 71 opened inside the operating table 1, a double-threaded rod 72 is rotatably mounted inside the groove body 71, slide plates 73 are threadedly mounted on both sides of the surface of the double-threaded rod 72, guide frames 74 are fixedly mounted on the tops of the two slide plates 73, and a plurality of guide rollers 75 are rotatably mounted inside the guide frame 74.

[0029] In this embodiment, the protective film to be inspected is placed on four guide rotating rollers 6, and the protective film is inspected in real time by two crystal point detectors 5 on the gantry 3. As the protective film moves, the surface of the protective film is continuously inspected, and the information is fed back to the control screen 14. The double-threaded rod 72 can be rotated and adjusted conveniently by turning the hand wheel 8. The rotation of the double-threaded rod 72 drives the two slides 73 to approach each other. The two guide frames 74 are located on both sides of the protective film. The movement of the protective film will touch the guide roller 75 in the guide frame 74. The guide roller 75 rotates in the guide frame 74 to reduce friction, which has a guiding effect on the transportation of the protective film.

[0030] Specifically, one end of the double threaded rod 72 passes through one side of the operating table 1 and is fixedly mounted with a hand wheel 8, and an armrest 9 is rotatably mounted on one side of the hand wheel 8, and the hand wheel 8 is set to be hollow. The above design facilitates the rotation of the hand wheel 8, and the armrest 9 and the hollow hand wheel 8 have the effect of saving resources.

[0031] Specifically, the two slide plates 73 are slidably mounted with the balancing pole 10, and the top of the balancing pole 10 is fixedly mounted on the bottom of the operating platform 1. The above design enhances the stability of the movement of the two slide plates 73 and enhances the balance of the movement of the two guide frames 74.

[0032] Specifically, the adjusting member 4 includes a cylinder 41 and a lifting plate 42. Two cylinders 41 are embedded in the top of the gantry 3. The lower ends of the two cylinders 41 are fixedly mounted with the lifting plate 42, and one side of the crystal point detector 5 is fixedly mounted on the surface of the lifting plate 42. In the above design, the two cylinders 41 are synchronous cylinders 41. The starting cylinder 41 drives the lifting plate 42 to move, thereby controlling the height adjustment of the two crystal point detectors 5 to avoid the crystal point detector 5 being fixed and unable to get close to the protective film for better detection.

[0033] Specifically, an auxiliary lighting lamp 11 is provided at the bottom of the crystal point detector 5, and the auxiliary lighting lamp 11 is fixedly installed on the top of the operating table 1. In the above design, the auxiliary lighting lamp 11 is arranged in a strip shape and installed on the top of the operating table 1, so that the protective film can be observed more carefully and has a fill light function.

[0034] Specifically, the balancing wheels 12 are installed on both sides of the lifting plate 42, and the slide grooves 13 for the balancing wheels 12 to slide are opened on both sides of the inner wall of the gantry 3. The above design, during the movement of the lifting plate 42, will drive the balancing wheel 12 to slide in the slide groove 13 on the inner wall of the gantry 3, reduce the friction force for the height adjustment of the lifting plate 42, relieve the pressure of the cylinder 41, and extend the service life of the cylinder 41.

[0035] Specifically, a control screen 14, an alarm 15 and an emergency stop button 16 electrically connected to the crystal point detector 5 are installed on the top of the operating table 1. In the above design, the detection data of the crystal point detector 5 is reflected on the control screen 14, and the emergency stop button 16 can be used manually to control the transportation of the protective film. At the same time, when the crystal point detector 5 detects crystal points on the protective film, it stops working immediately, and the alarm 15 will sound an alarm to remind the staff.
