Description

Technical Field

[0001] This utility model relates to the field of coated lens processing technology, specifically to a testing device for coated lenses. Background Technology

[0002] Puncture testing of coated lenses is commonly used in safety eyewear (such as lenses for industrial and military applications that need to withstand impacts from metal fragments and sharp objects), special-function coated lenses (such as conductive ITO films, whose mechanical strength is also part of the performance indicators), and quality verification of high-end durable lenses. By using probes of specific shapes and hardness to impact the lens surface with standardized forces, it is possible to assess whether the coating will peel off, crack, or the substrate will break. This not only meets the stringent requirements of safety regulations (such as safety standards for protective equipment) and prevents the risk of lens failure due to sudden impacts in actual use, but also verifies the bonding quality between the coating and the substrate (such as adhesion enhanced by technologies like ion bombardment), and provides key data for improving the coating process. It is a crucial quality control step to ensure the safe application of lenses for special equipment in high-risk environments.

[0003] Existing technologies for puncture testing of coated lenses used on special equipment lack effective and complete automated production line equipment, resulting in low overall testing efficiency and difficulty in controlling accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a testing device for coated lenses, which solves the problems of the lack of effective and complete assembly line equipment for puncture testing of coated lenses used on special equipment, resulting in low overall testing efficiency and difficulty in controlling accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A testing device for coated lenses includes a base and a conveyor line disposed within the inner cavity of the base. Multiple placement seats are fixedly mounted on the conveyor line, which drives the placement seats to reciprocate in a cyclical motion. A placement slot for accommodating the coated lens to be tested is opened in the middle of the placement seat. A piercing post is movably arranged in the middle of the base via a mounting frame. The piercing post can elastically reciprocate on the mounting frame. A rotatable cam is arranged at the upper end of the piercing post, and the cam drives the piercing post to reciprocate along the axial direction during rotation. A sensing plate is fixedly mounted on the outer surface of the placement seat, and a proximity switch that cooperates with the sensing plate is provided on the side wall of the base.

[0007] Preferably, an industrial camera is fixedly mounted on the base via a mounting bracket to capture and upload images of the coated lens to be tested after puncture. When the coated lens to be tested is located at the puncture position on one mounting base, the other mounting base is within the shooting range of the industrial camera.

[0008] Preferably, a material-picking robotic arm is provided on one side of the base, and a negative pressure suction cup is provided at the movable end of the material-picking robotic arm. The material-picking robotic arm is used to pick up the coated lens after it has been photographed in the slot by adsorbing the negative pressure suction cup.

[0009] Preferably, a limiting shell is fixedly provided on the mounting frame, the piercing post passes through the mounting frame and is slidably connected to it, L-shaped frames are symmetrically arranged on the outer surface of the upper part of the piercing post, and a spring is sleeved on the outside of the piercing post, with the spring limiting arrangement between the limiting shell and the L-shaped frame.

[0010] Preferably, the top of the piercing post has a slot that matches the cam, and the cam always contacts the bottom of the slot during its rotation.

[0011] Preferably, one end of the cam is connected to a drive motor, and the drive motor is suspended above the mounting bracket via a support.

[0012] This utility model has the following beneficial effects:

[0013] This testing equipment for coated lenses uses proximity switches and sensors to precisely stop the conveyor line, ensuring the lens to be tested is positioned at the puncture point. Simultaneously, it controls the drive assembly to rotate the cam, which in turn drives the puncture needle at a constant speed and force to perform puncture tests on the lens. The entire production line operates stably and efficiently. The proximity switches, in conjunction with a timer, intermittently start and stop the conveyor line and the drive cam, enabling cyclic testing of the coated lenses on the mounting base, ensuring overall efficiency and a high level of automation.

[0018] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] A testing device for coated lenses includes a base 1 and a conveyor line 2 disposed within the cavity of the base 1. Multiple placement seats 3 are fixedly disposed on the conveyor line 2, which drives the placement seats 3 to reciprocate. A placement slot 4 is provided in the middle of the placement seat 3 to accommodate the coated lens to be tested. A piercing post 8 is movably arranged in the middle of the base 1 via a mounting frame 7. The piercing post 8 can reciprocate elastically on the mounting frame 7. A rotatable cam 10 is arranged at the upper end of the piercing post 8, and the cam 10 drives the piercing post 8 to reciprocate along the axial direction during rotation. A sensing plate 5 is fixedly disposed on the outer surface of the placement seat 3, and a proximity switch 6 that cooperates with the sensing plate 5 is disposed on the side wall of the base 1.

[0020] like Figure 1 and Figure 2 As shown, in the above technical solution, the proximity switch 6 and the sensing element 5 are used to precisely stop the conveyor line 2, thereby ensuring that the coated lens to be tested is positioned at the puncture point. Simultaneously, the drive assembly can be synchronously controlled to rotate the cam 10, which in turn drives the puncture needle to perform a puncture test on the lens at a constant speed and force. The entire production line operates stably and efficiently. The proximity switch 6 can work with a timer to intermittently start and stop the drive assembly of the conveyor line 2 and the drive cam 10, enabling cyclic testing of the coated lens on the placement seat 3, ensuring overall work efficiency and a high degree of intelligence.

[0021] An industrial camera 11 is fixedly mounted on the base 1 via a mounting bracket 7. This camera is used to capture and upload images of the coated lens under test after puncture. When the coated lens under test is located at the puncture position on one mounting base 3, the other mounting base 3 is within the shooting range of the industrial camera 11. Figure 1 As shown, in this technical solution, the industrial camera 11 facilitates the acquisition of electronic data of the punctured coated lens for subsequent data analysis. By controlling the distance between the placement seats 3, the position of the coated lens to be tested on the placement seat 3 can be controlled by a single set of proximity switches 6. This allows image acquisition and puncture testing to be completed even when the conveyor line 2 is stopped, improving overall work efficiency.

[0022] A material-picking robotic arm 12 is installed on one side of the base 1. The movable end of the robotic arm 12 is equipped with a negative pressure suction cup. The robotic arm 12 is used to pick up the coated lens after it has been photographed from the placement slot 4 by adsorbing the negative pressure suction cup. For example... Figure 2As shown, in this technical solution, the robotic arm 12 can automatically pick up the coated lens in the placement slot 4 during the process of the industrial camera 11 taking pictures, so that the placement seat 3 can be used repeatedly, thereby improving the automation of the entire testing production line and improving the overall testing efficiency.

[0023] A limiting shell 81 is fixedly installed on the mounting bracket 7. The piercing post 8 penetrates the mounting bracket 7 and is slidably connected to it. L-shaped frames 83 are symmetrically arranged on the upper outer surface of the piercing post 8. A spring 82 is sleeved on the outside of the piercing post 8, and the spring 82 is positioned between the limiting shell 81 and the L-shaped frame 83 for limiting. Figure 2 and Figure 3 As shown, in this technical solution, the limiting shell 81 and L-shaped frame 83 can ensure that the spring 82 can drive the piercing column 8 to return to a stable position during the reciprocating motion of the piercing column 8, thus ensuring the stability and accuracy of the cyclic piercing. At the same time, the position of the spring 82 is limited to prevent the stroke of the piercing column 8 from deviating during the elastic return process.

[0024] The top of the piercing post 8 has a slot that matches the cam 10, and the cam 10 always contacts the bottom of the slot during its rotation. Figure 2 and Figure 3 As shown, in this technical solution, by opening a slot at the top of the piercing post 8, it can be ensured that the cam 10 is always located in the slot during the rotation process, so as to avoid the cam 10 from wobbling during long-term operation, further ensuring that the piercing post 8 always pierces accurately, and the piercing position is not easily affected by the external environment, thereby improving the overall detection accuracy.

[0025] One end of the cam 10 is connected to the drive motor 9, which is suspended above the mounting bracket 7 via a support. Figure 2 As shown, in this technical solution, the cam 10 is directly driven to rotate by the drive motor 9, thereby realizing the puncture column 8 to move cyclically along the axial direction, thus completing the puncture test on the coated lens to be tested. The overall transmission scheme is simple and has low loss. At the same time, the drive motor 9 can be a servo motor, so as to cooperate with the proximity switch 6 for timed start and stop control.
