Description

Technical Field

[0001] This utility model relates to the field of optical component processing equipment technology, and in particular to a tool for trimming the edge of adhesive backing on camera lenses. Background Technology

[0002] With the rapid development of consumer electronics, camera modules have become core components of smartphones and tablets. Imaging quality and manufacturing precision directly affect user experience. In the production and assembly process of camera modules, camera lenses need to be glued to a designated base using adhesive. Due to limitations in the adhesive application process, the adhesive may overflow and become irregular at the edge of the lens after bonding, resulting in excess adhesive edges.

[0003] This excess adhesive not only affects the product's aesthetics, but more importantly, it interferes with subsequent assembly precision and can even impact the sealing performance and long-term reliability of the entire module. Therefore, precise circumferential trimming of the adhesive edges on camera lenses to remove excess material is a necessary and crucial step in the production process. Currently, the industry primarily relies on manual labor for trimming adhesive edges, where workers use hand-held tools to scrape it off under a microscope. This method has significant drawbacks: firstly, it's inefficient and cannot meet the demands of large-scale production; secondly, the trimming quality depends entirely on the worker's skill level and work condition, leading to poor product consistency and a high defect rate. In the delicate manual operation, the slightest carelessness can cause the blade to scratch the surface of the lens, resulting in permanent damage to the optical components and directly leading to product scrapping. To improve this situation, some simple semi-automatic tools have emerged, such as using a simple rotary table to drive the lens to rotate. However, the positioning of the scraper and the control of the cutting force still need to be done manually. Although this method improves efficiency to some extent, due to the lack of a precise automated control mechanism, it is difficult to ensure that the angle, position, and adhesion force of the scraper to the adhesive are constant, resulting in low trimming accuracy. In addition, the clamping mechanism is relatively simple in design, and there may be problems such as insufficient clamping or damage to the lens due to uneven clamping force during rotation.

[0004] Therefore, this utility model proposes a tool for trimming the edge of the adhesive backing of camera lenses to address the shortcomings of existing technologies. Utility Model Content

One end of the second electric push rod is rotatably connected to the base via the third rotating joint, and the other end is rotatably connected to the adjusting arm via the second rotating joint. The scraper is mounted on the adjusting arm.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0025] Example:

[0026] Please refer to Figures 1 to 4 This utility model provides a tool for trimming the adhesive edges of camera lenses, aiming to solve the problems of low efficiency, unstable precision, and easy damage to the lenses in the prior art. Specifically, as shown in the example... Figure 1 and Figure 2As shown, the overall frame of the camera lens adhesive edge trimming tool is built on a flat and stable base 1. Base 1 provides a unified mounting reference for all functional components. A base 2 is fixedly connected to the center of the top of base 1. Base 2 is used to raise the height of the rotating work platform. A pre-set circular groove is machined on the top surface of base 2. A bearing 3 is installed in the circular groove of base 2 by an embedded fit. A support 5 for directly supporting the camera lens is fixedly connected to the inner ring of bearing 3 at its bottom. The top of support 5 is a flat bearing surface. Support 5 forms a stable rotational connection with base 2 through bearing 3, thus forming a rotating platform structure for driving the lens to rotate. To achieve automated rotation, a motor 4 is fixedly installed in the groove on the top of base 1. The installation position of motor 4 makes the center of gravity low, increasing the stability of the equipment. The top output shaft of motor 4 Extending upwards and connecting to the bottom center of the receiving seat 5, it provides rotational power to the receiving seat 5. Meanwhile, in order to construct the subsequent clamping and trimming structure, a gantry-type bracket 7 is fixedly connected to the top periphery of the base 1 by welding or screwing. The bracket 7 spans across the top of the receiving seat 5, providing a support point for the installation of the clamping structure. In addition, a rotating joint 14 is fixedly connected to one side surface of the base 1, and a rotating joint 3 16 is also fixedly connected to the top rear side of the base 1. The rotating joint 14 and the rotating joint 3 16 together serve as the pivot point for connecting the trimming structure and the base 1, defining the motion reference of the trimming structure. In this way, by uniformly installing the rotating platform, the bracket 7 of the clamping structure, and the rotating joints 14 and 3 16 of the trimming structure on the base 1, a comprehensive technical solution with clear functional divisions and a stable and reliable structure is formed.

[0027] like Figure 1 and Figure 4As shown, the trimming structure of the camera lens adhesive edge trimming tool, which is the core for achieving precise trimming, is designed as a precision linkage mechanism with multiple components working together. The adjusting arm 12 serves as the direct support for the scraper 13. One end of the adjusting arm 12 is rotatably connected to one side surface of the base 1 via a rotating joint 14. The rotating joint 14 provides a stable fulcrum for the swing of the adjusting arm 12. On the inner side of the adjusting arm 12, that is, the side facing the receiving seat 5, the scraper 13 is fixedly installed by bolts 6. The use of bolts 6 for fixing not only ensures the stability of the scraper 13 during operation, but also facilitates subsequent replacement or angle adjustment due to wear. Fine-tuning provides convenience. The precise movement of the adjusting arm 12 is driven by the electric push rod 11. The bottom fixed end of the electric push rod 11 is rotatably connected to the top rear side of the base 1 through the rotating joint 16, while the top telescopic end of the electric push rod 11 is rotatably connected to the rear side of the adjusting arm 12 through the rotating joint 15. The rotating joint 15 is pre-fixed to the rear side of the adjusting arm 12. In this way, the telescopic movement of the electric push rod 11 can be transmitted through the rotating joint 15 and the rotating joint 16 to drive the adjusting arm 12 to swing precisely around the axis of the rotating joint 14, thereby achieving precise control over the trimming position and application force of the scraper 13.

[0028] As another preferred embodiment, to ensure the accuracy of the installation positions of each functional component and the stability of the overall operation, the structural layout of the camera lens adhesive edge trimming tool has also been optimized. Specifically, the bottom of the bracket 7 is fixed to the top periphery of the base 1. This layout provides a solid installation foundation for the clamping structure and prevents shaking during operation. The top fixed end of the electric push rod 8 is installed on the inner side of the top crossbeam of the bracket 7, ensuring that the thrust of the electric push rod 8 can act vertically downward on the clamp 9. To achieve smooth rotation of the support seat 5, the motor 4 is fixed as a whole in the groove opened on the top of the base 1, and the top output axis of the motor 4 passes through the groove upward. The base 2 has a pre-drilled central through hole that is firmly connected to the bottom center of the support 5, forming a direct drive relationship. The way the motor 4 is installed by sinking it down effectively lowers the overall center of gravity of the equipment and improves the stability of operation. At the same time, the pre-drilled circular groove on the top of the base 2 is precisely matched with the outer ring size of the bearing 3. The bearing 3 is embedded in the bearing by a tight fit, providing the support 5 with low resistance and no radial wobbling rotational support. In addition, the rubber pads 10 at the bottom of the clamp 9 are designed to be four in number and are attached in an inclined state, so that the bottom of the four rubber pads 10 together form a downward convex arc surface, which can adaptively fit the surface of the lens when pressing the lens to achieve uniform pressure.

[0029] Working principle: First, place the camera lens with adhesive backing on the flat bearing surface on top of the receiving seat 5, ensuring that the lens is centered. Then, the control system starts the electric push rod 8. The telescopic end of the electric push rod 8 extends downward, pushing the clamp 9 connected to it to move downward in sync. The four rubber pads 10 at the bottom of the clamp 9 gradually approach and finally contact the top surface of the lens. Due to the arc structure formed by the four rubber pads 10, the clamp 9 can adapt well to the curvature of the lens surface, achieving uniform pressure distribution. The electric push rod 8 continues to apply pressure until the lens is firmly clamped on the receiving seat 5, effectively preventing any displacement or vibration of the lens during the subsequent high-speed rotation trimming process, thus completing the lens loading and clamping process.

[0030] Entering the positioning stage of the scraper 13, the control system starts the electric push rod 11. The telescopic end of the electric push rod 11 begins to move. When the telescopic end of the electric push rod 11 extends, it pushes the rear side of the adjusting arm 12 connected to the rotation, causing the adjusting arm 12 to swing around the axis of the rotating joint 14. This drives the scraper 13 installed on the inner side of the adjusting arm 12 to move closer to the edge of the lens at the center of the receiving seat 5. By precisely controlling the telescopic stroke of the electric push rod 11, the blade of the scraper 13 can be accurately and gently attached to the edge of the excess adhesive on the camera lens, completing the precise determination of the trimming position. At this time, the angle and initial attachment force of the scraper 13 have also been set. After completing the above preparations, the trimming operation officially begins. The control system starts the motor 4 installed in the groove of the base 1. The output shaft of the motor 4 begins to rotate. Through the connection with the bottom of the receiving seat 5, it drives the receiving seat 5 and the clamped lens to rotate stably and smoothly at high speed through the bearing 3.

[0031] The scraper 13, supported by the electric push rod 11 and the multi-joint mechanism, remains in a fixed position. When the rotating adhesive edge passes the stationary scraper 13, the excess part is continuously and evenly scraped and removed in a circular motion. During the entire finishing process, the adhesion force between the scraper 13 and the adhesive edge can be dynamically adjusted by finely adjusting the extension and retraction of the electric push rod 11 to adapt to the requirements of different adhesive materials or thicknesses, thereby ensuring the best finishing quality and smoothness. After the finishing operation is completed, the control system first shuts down the motor 4, and the receiving seat 5 and the lens stop rotating. Then, the control system can selectively move the electric push rod 11 in the reverse direction to make the scraper 13 detach from the lens. Finally, the electric push rod 8 is activated to retract in the reverse direction, driving the clamp 9 to lift upward and release the clamp on the lens. The operator can then easily remove the lens with the finished adhesive edge from the receiving seat 5. Thus, the entire automated and high-precision finishing process is completed.
