Description

Technical Field

[0001] The utility model relates to the technical field of optical films, in particular to an optical film collecting device. Background Art

[0002] Optical film is a type of optical medium material composed of thin layered media that propagates light beams through interfaces. The application of optical thin films began in the 1930s. Nowadays, optical films have been widely used in the fields of optics and optoelectronics to manufacture various optical instruments. The main optical film devices include reflective films, anti-reflective films, polarizing films, interference filters, spectroscopes, etc. They have been widely used in national economy and national defense construction, and have received increasing attention from scientific and technological workers.

[0003] In the production process of optical films, after the optical films are cut, they are moved to a collecting device via a conveyor belt. However, the cut optical films fall on the conveyor belt in different directions, making it impossible for the collecting device to collect all the optical films, resulting in possible omissions. Currently, the position of the optical films needs to be manually adjusted to facilitate collection by the collecting device, which increases the workload and has low efficiency.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] See also Figure 1-3 , an optical film collecting device, comprising a support frame 1, on which a driving roller and a driven roller are rotatably provided respectively, and the driving roller and the driven roller are connected by a transmission belt 11, and the support frame 1 is also provided with a first motor for driving the driving roller, and the support frame 1 is also provided with a positioning mechanism 2, and the positioning mechanism 2 includes a left support rod 21 and a right support rod 22 respectively fixed on both sides of the support frame 1, and the left support rod 21 and the right support rod 22 are both inclined. The left support rod 21 is rotatably connected to a plurality of first rotating wheels 23, and the right support rod 22 is rotatably connected to a plurality of second rotating wheels 24, each of the first rotating wheels 23 is connected by a first belt 25, and each of the second rotating wheels 24 is connected by a second belt 26; the support frame 1 is also provided with a driving mechanism 3, which is used to drive the first belt 25 and the second belt 26 to rotate, and the rotation directions of the first belt 25 and the second belt 26 are opposite.

[0024] By setting the alignment mechanism 2, when the optical film on the transmission belt 11 passes through the area of ​​the alignment mechanism 2, the two ends thereof are respectively in contact with the first belt 25 and the second belt 26. Since the first belt 25 and the second belt 26 rotate in opposite directions, the optical film rotates under the action of the torque. Due to the inclined setting of the left support rod 21 and the right support rod 22, the optical film is finally adjusted to have its long side parallel to the transmission direction of the transmission belt 11, which greatly facilitates the collection of the optical film by the collection device and avoids the phenomenon of missed collection of the optical film.

[0025] Furthermore, a left guide rod 41 and a right guide rod 42 are fixedly provided on the support frame 1 , respectively. The left guide rod 41 and the right guide rod 42 are both inclined, and the left guide rod 41 and the right guide rod 42 are not perpendicular.

[0026] The left guide rod 41 and the right guide rod 42 are used to preliminarily guide the position of the optical film and preliminarily adjust the optical film of the transmission belt 11 to the same position. On the one hand, the position of the optical film is adjusted to a uniform form, reducing the rotation angle of the optical film at different angles of the alignment mechanism 2, and improving the efficiency of the alignment mechanism 2 in adjusting the position. On the other hand, the position of the optical film is adjusted to a direction that is more suitable for the rotation of the torque, avoiding rotating a larger circle to complete the position adjustment, and avoiding blockage caused by the long time spent adjusting the position of the optical film.

[0027] Furthermore, a left baffle 43 and a right baffle 44 are provided on the support frame 1, and the left baffle 43 and the right baffle 44 are respectively connected to the left support rod 21 and the right support rod 22, and from the alignment mechanism 2 to the end of the conveyor belt, the spacing between the left baffle 43 and the right baffle 44 is reduced to be larger than the width of the optical film.

[0028] Due to the difference in the position distribution of the optical film on the transmission belt 11, after some optical films pass through the alignment mechanism 2, although their long sides are parallel to the direction of the transmission belt 11, the distribution positions are not in a straight line, which brings trouble to the collection of the optical film. The left baffle 43 and the right baffle 44 form a channel for the optical film to pass through, and guide the optical film to move along the left baffle 43 or the right baffle 44 until the moving path of each optical film is in a straight line.

[0029] Further, the driving mechanism 3 includes a second motor 31 fixedly arranged on the support frame 1, a driving gear 32 is fixedly connected to the output shaft of the second motor 31, the driving gear 32 is meshedly connected to a left gear 33 and a right gear 34, respectively, and the left gear 33 and the right gear 34 are respectively connected to a transmission assembly. The transmission assembly includes a left rotating shaft 35 and a right rotating shaft 36 respectively rotatably connected to the support frame 1, the left gear 33 and the right gear 34 are respectively fixedly connected to the left rotating shaft 35 and the right rotating shaft 36, and the left rotating shaft 35 and the right rotating shaft 36 are respectively fixedly connected to a left pulley 37 and a right pulley 38, the left pulley 37 is connected to each first rotating wheel 23 through a first belt 25, and the right pulley 38 is connected to each second rotating wheel 24 through a second belt 26.

[0030] The second motor 31 drives the left gear 33 and the right gear 34 to rotate through the driving gear 32. The left gear 33 rotates and drives the left pulley 37 to rotate through the left shaft 35. The left pulley 37 rotates and cooperates with the first rotating wheel 23 to rotate the first belt 25. Similarly, the second belt 26 rotates, and the first belt 25 and the second belt 26 rotate in opposite directions.

[0031] Furthermore, each of the first belt 25 and the second belt 26 is provided with a protective layer to prevent the first belt 25 and the second belt 26 from abrading the optical film.

[0032] Working principle:

[0033] After the optical film is cut, it passes through the left guide rod 41 and the right guide rod 42 for preliminary position adjustment; the second motor 31 drives the left gear 33 and the right gear 34 to rotate through the driving gear 32, and the left gear 33 rotates through the left rotating shaft 35 to drive the left pulley 37 to rotate, and the left pulley 37 rotates by cooperating with the first rotating wheel 23, so that the first belt 25 rotates. Similarly, the second belt 26 rotates, and the first belt 25 and the second belt 26 rotate in opposite directions. The optical film rotates under the action of the torque and passes through the channel formed by the left baffle 43 and the right baffle 44 to facilitate the collection of the optical film.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
