Description

Technical Field

[0001] This utility model relates to the field of adhesive cleaning technology for ND lenses of drones, and in particular to an automatic adhesive cleaning device for ND lenses of drones. Background Technology

[0002] In drone camera systems, neutral density filters (ND filters) are key optical components for adjusting the amount of light entering the lens. Their structure mainly consists of a frame, optical lenses, and positioning steel plates, which are assembled by layering them with black adhesive. Currently, the assembly process of ND filters in the industry generally relies on manual operation, with operators manually completing processes such as aligning and bonding the lenses and steel plates, applying adhesive for fixation, and controlling the adhesive layer.

[0003] However, it is difficult to precisely control the amount of adhesive applied manually, and the adhesive easily overflows from the edge where the lens and steel sheet meet. The overflowing adhesive will form irreversible solidification residue during the subsequent baking and curing stage, causing contamination of the optical transmission area or structural deformation, resulting in product scrap. Utility Model Content

[0004] Based on this, the present invention provides an automatic adhesive application device for ND mirrors of drones. It has a simple structure and is easy to use. Through the coordinated action of the adhesive application head and the adjustment head, along with the guide roller and the traction module, the downward pressing action of the adhesive application head is completely independent of the conveying speed of the non-woven fabric belt. When the adhesive application head is in action, it can maintain the relative stability of the overall tension of the non-woven fabric belt.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Please see Figures 1 to 7 The present invention provides an automatic adhesive application device for ND lenses of drones, comprising a feeding component 10, a transfer component 20 mounted on one side of the feeding component 10, and an adhesive application component 30 mounted on the transfer component 20.

[0033] The feeding assembly 10 includes a Y-axis linear module 11, a double-row synchronous belt conveyor 12 mounted on the Y-axis linear module 11, limiting pressure plates 13 mounted on opposite sides of the top of the double-row synchronous belt conveyor 12, a lifting cylinder 14 mounted in the middle of the double-row synchronous belt conveyor 12, and a lifting plate 15 connected to the piston rod of the lifting cylinder 14. The double-row synchronous belt conveyor 12 is set along the Y-axis direction and is used to transport a tray 16, the interior of which is used to hold multiple ND mirrors to be coated with adhesive.

[0034] Specifically, the conveying direction of the double-row synchronous belt conveyor 12 is set along the X-axis, and the pallet 16 passes between the belt of the double-row synchronous belt conveyor 12 and the limiting pressure plate 13. During glue application, the lifting cylinder 14 drives the lifting plate 15 to lift the pallet 16, so that the top surface of the pallet 16 abuts against the limiting pressure plate 13, thereby positioning the pallet 16 and facilitating the subsequent glue application operation of the glue application assembly 30.

[0035] In this embodiment, the top surface of the lifting plate 15 is provided with a positioning pin, and the tray 16 is provided with a positioning hole. The positioning hole corresponds to the positioning pin, which facilitates the lifting plate 15 to position and lift the tray 16.

[0036] The transfer assembly 20 includes an X-axis linear module 21 located above the Y-axis linear module 11, a bracket 22 connected to the X-axis linear module 21, a feeding tray 23 mounted on one side of the bracket 22, a receiving tray 24 mounted on the other side of the bracket 22, and a vision detector mounted on the top front of the bracket 22. The vision detector is positioned directly above the Y-axis linear module 11 and is used to detect the ND mirror inside the tray 16 for positioning and adhesive application. The feeding tray 23 stores unused non-woven fabric strips, and the receiving tray 24 stores used non-woven fabric strips.

[0037] In this embodiment, the visual detector includes a CCD camera 25 mounted on the top front of the bracket 22, a magnifying lens 26 coaxially connected to the CCD camera 25, and a ring light source 27 coaxially mounted below the magnifying lens 26.

[0038] The adhesive application assembly 30 includes an adhesive application head 31 that can be raised and lowered and installed at the bottom front end of the bracket 22, an adjustment head 32 that can be raised and lowered and installed on one side of the adhesive application head 31, a plurality of guide rollers 33 spaced around the adhesive application head 31 and the adjustment head 32, a guide roller 34 installed on one side of the top front end of the bracket 22, and a traction module installed on the other side of the top front end of the bracket 22. The guide roller 34 is close to the feeding tray 23 and is used to guide and convey the nonwoven fabric strip, allowing the nonwoven fabric strip to be smoothly fed into the guide roller 33.

[0039] Both the wiping head 31 and the adjusting head 32 are used to press down against the non-woven fabric tape. The lifting and lowering movements of the wiping head 31 and the adjusting head 32 are opposite; that is, when the wiping head 31 presses down, the adjusting head 32 lifts up, and when the wiping head 31 lifts up, the adjusting head 32 presses down. This design allows the wiping head 31 to move independently and flexibly downwards without stopping or changing the overall conveying speed of the non-woven fabric tape, so as to contact the ND mirror with the non-woven fabric tape for wiping adhesive, and to precisely control the amount of downward pressure (i.e., the wiping force). After wiping is completed, the wiping head 31 can be lifted back to its original position, preparing for the next ND mirror or position.

[0040] Specifically, the wiping head 31 and the adjusting head 32 are spatially separated by a certain distance, and together with the guide rollers 33 around them, they form a path for a nonwoven fabric belt.

[0041] In the non-adhesive application state, the adhesive application head 31 is in the raised state and does not press down on the nonwoven fabric strip. Meanwhile, the adjusting head 32 is in the pressed state, pressing down on the nonwoven fabric strip. Due to the pressing action of the adjusting head 32, an additional length of nonwoven fabric strip is stored (equivalent to pulling the nonwoven fabric strip downwards a bit more), creating a fabric buffer zone, making the nonwoven fabric strip corresponding to the position of the adhesive application head 31 relatively loose or in a "reserve" state.

[0042] When adhesive application is needed, the adjusting head 32 is raised while the adhesive application head 31 is pressed down. The adjusting head 32 releases the previous fabric buffer area, and the pressing down of the adhesive application head 31 utilizes the length of this released non-woven fabric strip, stretching the non-woven fabric strip at the position of the adhesive application head 31 downwards so that it contacts the ND mirror below for adhesive application. After adhesive application is complete, the adjusting head 32 and the adhesive application head 31 reset, establishing a new fabric buffer area and storing a new length of non-woven fabric strip for future use by the adhesive application head 31.

[0043] During this process, the amount of pressure applied by the adhesive head 31 can be flexibly controlled, thereby controlling the pressure applied by the non-woven fabric strip to the ND mirror, achieving the effect of adjusting the adhesive application force.

[0044] This design allows the nonwoven fabric belt to maintain a constant conveying speed while independently and flexibly controlling the downward action and amplitude of the adhesive application head 31. It eliminates the need to start and stop the traction module for each adhesive application, thus improving efficiency and accuracy.

[0045] In this embodiment, the axis of the guide roller 33 is aligned with the Y-axis, and the axis of the guide roller 34 is aligned with the X-axis.

[0046] In this embodiment, the traction module includes a traction motor 351 mounted on the bracket 22, a traction roller 352 coaxially connected to the rotor of the traction motor 351, a pressing cylinder 353 mounted above the traction motor 351, and a pressing wheel 354 connected to the end of the piston rod of the pressing cylinder 353. The pressing wheel 354 is correspondingly arranged with the traction roller 352. The space between the pressing wheel 354 and the traction roller 352 is used for the non-woven fabric strip to pass through, so as to generate traction force on the non-woven fabric strip, so that it is collected into the inside of the receiving tray 24 after passing through the adjusting head 32 and the wiping head 31.

[0047] Furthermore, to better guide the conveying of the nonwoven fabric strip, the adhesive application assembly 30 also includes a clamping block 36 installed below the guide roller 34, a clamping cylinder 37 correspondingly disposed on one side of the clamping block 36, and a strip detection sensor 38 located below the clamping block 36; the strip detection sensor 38 is located on one side of the nonwoven fabric strip. The gap between the clamping block 36 and the clamping cylinder 37 is used for the nonwoven fabric strip to pass through, which can effectively improve the smoothness of the nonwoven fabric strip during conveying and reduce the vibration of the nonwoven fabric strip.

[0048] In this embodiment, both the adhesive wiping head 31 and the adjusting head 32 are mounted on the bracket 22 via the lifting cylinder 39.

[0049] The aforementioned automatic adhesive application device for ND lenses of drones has a simple structure and is easy to use. Through the coordinated action of the adhesive application head 31 and the adjustment head 32, along with the guide roller 33 and the traction module, the downward pressing action of the adhesive application head 31 is completely independent of the conveying speed of the non-woven fabric belt. When the adhesive application head 31 is in action, it can maintain the relative stability of the overall tension of the non-woven fabric belt, without the need to start, stop or change speed to coordinate with adhesive application, which greatly improves efficiency and stability.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
