Description

Technical Field

[0001] This utility model relates to the field of optical automation equipment technology, specifically to an automatic batch feeding and calibration device for optical films. Background Technology

[0002] Optical films, as special materials composed of thin, layered media, primarily function to propagate light beams through interfaces and are widely used in various optical devices, such as lenses and displays. The quality of optical films directly affects the performance of optical devices; therefore, their manufacturing and processing are particularly important. In the manufacturing process of optical films, multiple layers of thin films with different functions are typically laminated together to form composite films with specific optical properties.

[0003] Optical films are typically manufactured in rolls, a convenient arrangement for storage and transportation. However, in practical use, these rolls need to be cut into individual sheets to meet the requirements of different optical devices. The cutting precision and quality of the optical film directly impact the performance of the subsequent optical devices. Furthermore, optical films are susceptible to various factors during manufacturing, such as dust and scratches, all of which can degrade their quality and consequently affect the performance of the optical devices.

[0004] To ensure the quality of optical films, rigorous quality inspection is required after manufacturing. This process involves placing the optical film on a conveyor belt at the loading station of the quality inspection equipment, which then transports it to the inspection station for testing. However, existing optical film loading processes are prone to lateral misalignment. When the suction mechanism picks up tilted optical films, it causes inaccurate inspection, thus affecting the performance of the optical device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic batch feeding and calibration device for optical films, which solves the problems of lateral misalignment after feeding and inaccurate detection caused by the suction mechanism during the detection process.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0039] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0040] Reference Figure 1-6 This embodiment describes an automatic batch feeding and calibration device for optical films.

[0041] This application provides an automated batch feeding and calibration device for optical films, such as... Figure 1 As shown, it includes a feeding mechanism 200 and a suction mechanism 100. The feeding mechanism 200 includes a feeding conveyor belt 21 for carrying the optical film and transferring the optical film from the first station to the second station; the suction mechanism 100 is disposed above the second station and picks up the optical film on the second station.

[0042] The first station is located at the inlet end (i.e., the starting point) of the feeding conveyor belt 21, and the second station is located at the outlet end (i.e., the end point) of the feeding conveyor belt 21.

[0043] like Figure 1 As shown, it also includes a calibration mechanism 300, which includes a first side calibration component 31 and a second side calibration component 32 located on both sides of the first station on the feeding conveyor belt 21, and performs calibration during the transmission of the optical film on the first station to the second station.

[0044] Reference Figure 1 and Figure 3 In this embodiment, the first side calibration component 31 and the second side calibration component 32 are set on both sides of the first station of the feeding conveyor belt 21 as an example.

[0045] In this embodiment, the calibration mechanism 300 of the present invention is designed to calibrate the optical film as it travels from the first station to the second station, ensuring that the optical film is neatly arranged during its journey, thereby improving the gripping accuracy of the suction mechanism 100. It should be noted that in the prior art, each optical film is placed within a rigid carrier.

[0046] For example, the first side calibration assembly 31 includes a base, a belt 316, and a spindle 314.

[0047] Among them, such as Figure 5 As shown, the substrate is fixed to one side of the feeding conveyor belt 21. The substrate includes a first reference platform 311, which is fixed to the guard plate on the side of the feeding conveyor belt 21 or to the substrate that carries the feeding conveyor belt 21. A side stand 312 is provided on one side of the first reference platform 311, which extends upward and covers a part of the belt 316.

[0048] Both the upper and lower ends of the belt 316 are provided with caps 315, and the two shafts of the belt 316 are rotatably connected to the caps 315. The aforementioned main shaft 314 is rotatably connected to the first reference platform 311 and is located in the middle of the belt 316, specifically connected to the caps 315; a reference plate 318 is connected to one side of the caps 315, and the reference plate 318 is connected to the side stand 312 through an elastic member 317.

[0049] The belt 316 oscillates around the main shaft 314, making the conveying direction of the belt 316 horizontal or inclined with that of the feeding conveyor belt 21. When the optical film is conveyed on the feeding conveyor belt 21 towards the second station, the irregular carrier sidewalls carrying the optical film contact the belt 316, pushing the irregular carrier carrying the optical film back to the correct position.

[0050] It should be noted that belt 316 is perpendicular to the feeding conveyor belt 21, specifically, it is sideways, and its height is the same as or greater than the maximum height of the optical film stacking. Furthermore, the rotation direction of belt 316 is consistent with the conveying direction of feeding conveyor belt 21. This ensures that the stacked optical film is properly conveyed on feeding conveyor belt 21.

[0051] Furthermore, a cap 313 is provided on the side platform 312, and a cavity is formed inside the cap 313 to accommodate an elastic element 317, which includes a spring. In order to ensure that the belt 316 can be flush with the feeding conveyor belt 21, the spring is placed inside the cap 313. In this way, when the reference plate 318 is in contact with the side platform 312, the spring can be completely accommodated inside the cap 313, so that the reference plate 318 and the side platform 312 are completely in contact without gaps, ensuring that the belt 316 is flush with the feeding conveyor belt 21, and allowing the optical film to be conveyed flush on the feeding conveyor belt 21.

[0052] Furthermore, to adjust the tilt angle of the belt 316, a threaded hole adapted to the cap 313 is provided on the side stand 312. The cap 313 is threaded into the threaded hole and screws in and out within it. At this time, the connection between the spring and the cap 313 is rotatably connected. In use, rotating the cap 313 adjusts the extension length of the spring on the side stand 312, thereby adjusting the tilt angle of the belt 316 in its normal state.

[0053] For example, the second side calibration assembly 32 includes a second reference platform 321 and a plate frame. The second reference platform 321 is fixed to the other side of the feeding conveyor belt 21; the plate frame is vertically fixed on the second reference platform 321, and the plate frame is arranged opposite to the belt 316.

[0054] Specifically, the frame includes a horizontal frame 322 and a side wing plate 323, with the side wing plate 323 obliquely disposed on the horizontal frame 322. When the belt 316 is horizontal, the horizontal frame 322 is flush with the belt 316, and the space between the horizontal frame 322 and the belt 316 allows the optical film to pass through.

[0055] Furthermore, multiple rotatable rollers 324 are provided within the horizontal frame 322. When the optical film passes through the space between the horizontal frame 322 and the belt 316, the side wall of the carrier carrying the optical film contacts the rollers 324, at which time the rollers 324 rotate, allowing the optical film to be normally transported on the feeding conveyor belt 21.

[0056] It should be noted that, in its conventional form, such as Figure 4 As shown, the elastic element 317 extends outward, causing the belt 316 to swing and tilt about the main shaft 314. At this time, in the top view projection, an angle β is formed between the belt 316 and the feeding conveyor belt 21; while an angle α is formed between the side wing plate 323 and the horizontal frame 322, where α=β. Since the tilt angle of the belt 316 is formed by the extension of the spring, there may be cases where β>α or β<α. In this case, the cap 313 is used to adjust the angles so that they are the same or nearly the same. When the belt 316 is inclined, the inclined belt 316 and the inclined side wing plate 323 form a funnel shape at the first station. The optical film placed at the first station is located at this funnel shape. As the feeding conveyor belt 21 rotates, it moves the optical film to the second station. The uneven carrier sidewall of the optical film contacts the belt 316 and the side wing plate 323 until it enters the space between the horizontal frame 322 and the belt 316, at which point the optical film is reset to the correct position and calibrated. At this time, the belt 316 is horizontal. When the optical film moves out of the space between the horizontal frame 322 and the belt 316, the belt 316 swings and tilts around the main shaft 314 under the push of the spring, and continues to place the optical film for the next process.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
