Description

Technical Field

[0001] The present invention relates to the technical field of human eye visual characteristic defect detection, and particularly relates to a defect detection device based on human eye visual characteristics. Background Art

[0002] The most common human eye visual characteristic detection instrument is a vision tester. Vision testing instruments are widely used in fields such as ophthalmic medicine, vision examination, and visual health assessment. Their core function is to help determine the vision status of users through precise detection means. However, there are some deficiencies in the design of existing vision testers, which affect their stability and adaptability during actual use, especially in the design of the chin support and forehead support.

[0003] Firstly, the chin bracket of traditional vision testers usually adopts a fixed design, lacking flexibility in adapting to different facial structures. Since there are significant differences in the shape, depth, and height of each person's chin, it is difficult for a fixed bracket to ensure effective support for the chins of all users, resulting in instability during the test and even affecting the accuracy of the test results. Although some high-end devices attempt to provide a function for adjusting the height of the bracket, these adjustment ranges and adjustment methods still have limitations and cannot fully meet individual needs.

[0004] Secondly, current vision testers are not equipped with a forehead massage function. When conducting vision tests for a long time, users often feel discomfort or tension in the forehead area. The existing devices do not take this into account in their design and lack the function of providing comfort through forehead support. This not only affects the comfort of users but may also cause users to feel anxious or have muscle tension during use, thus affecting the detection effect.

[0005] In summary, there is a large room for improvement in the stability, adjustment flexibility, and user comfort of the existing vision testers in supporting the chin. Summary of the Invention

[0006] The purpose of the present invention is: to solve the above problems, the present invention provides a defect detection device based on human eye visual characteristics.

[0007] The present invention specifically adopts the following technical solutions to achieve the above purpose:

[0014] Further, the inner angles of two sides of the connecting plate are 120 degrees. In the initial state, one side of the connecting plate is in a straight line with the driven rotating plate.

[0015] Further, each group of the active rotating plates includes two active rotating plates. One end of the connecting plate is located between the two active rotating plates. The connecting plate is rotatably connected to the two active rotating plates. The turning point of the connecting plate is rotatably connected to one end of the driven rotating plate.

Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] A defect detection device based on the human eye visual characteristics according to a preferred embodiment of the present invention will be elaborated in detail below.

[0034] Embodiment 1, as Figures 1-9As shown in the figure, a defect detection device based on human eye visual characteristics includes a substrate 1. A vision detector 2 is provided on the substrate 1. A moving table 5 is provided below the substrate 1. The vision detector 2 includes a detector body 21 and a support bracket 22. A massage mechanism 3 and a support mechanism 4 are provided on the support bracket 22. A support plate 221 is fixedly installed on the support bracket 22. The massage mechanism 3 is arranged on the support plate 221. The massage mechanism 3 includes two groups of active rotating plates 31, two driven rotating plates 32 and two connecting plates 33. Three massage rollers 34 are rotatably connected to the two connecting plates 33. The three massage rollers 34 are arc-shaped. An installation plate 222 is fixedly installed on the support bracket 22. The support mechanism 4 is arranged on the installation plate 222. The support mechanism 4 includes a support plate 41, a rotating mechanism 42, a first electric telescopic rod 43 and a second electric telescopic rod 44. The support plate 41 is arranged on the rotating mechanism 42. The first electric telescopic rod 43 and the second electric telescopic rod 44 are connected to the rotating mechanism 42.

[0035] During operation, the detector body 21 is responsible for performing specific vision detection tasks. The massage mechanism 3 on the support bracket 22 is used to provide eye soothing services for the user before and after the detection. When the massage function is started, the two groups of active rotating plates 31 rotate. Since the two rotating wheels 11 fixedly installed at the ends of the two groups of active rotating plates 31 away from the connecting plates 33 are linked through the teeth 34 meshing with each other on the outer periphery, the connecting plates 33 rotatably connected thereto are driven to move. The connecting plates 33 drive the two driven rotating plates 32 rotatably connected thereto to act in coordination. Finally, the three arc-shaped massage rollers 34 rotatably connected to the two connecting plates 33 roll and massage around the user's eyes along a predetermined trajectory, effectively relieving eye fatigue and making the eye muscles in a relaxed state, which helps with subsequent accurate detection.

[0036] The function of the support mechanism 4 is to accurately position the user's head to ensure the detection accuracy. The support plate 41 is used to directly support the user's chin. The rotating mechanism 42 controls the angle adjustment of the support plate 41. The first electric telescopic rod 43 and the second electric telescopic rod 44 participate in the fine adjustment of the position of the support plate 41. The first rotating ball 431 at the telescopic end is rotatably connected to the square block 427. The fixed end is rotatably connected to the hemispherical base 225 installed on the installation plate 222 through the first connecting piece 432 and the second rotating ball 433. Through the telescopic cooperation of the two electric telescopic rods, the spatial position of the support plate 41 is accurately adjusted so that the user's eyes can be accurately aligned with the detection optical path of the vision detector 2, ensuring the detection accuracy.
