Description
Technical Field
[0001] The invention belongs to the technical field of umbrella testing, and in particular relates to an intelligent universal umbrella fatigue testing machine and a detection method thereof. Background Art
[0002] In the national standard "GB / T 23147-2018 Sunny Umbrella", the number of times the umbrella is opened and closed, the switch button force, the compression force of the umbrella pole, etc. are important indicators for judging whether the quality of the umbrella is qualified.
[0003] The current existing technology includes fixing the top of the umbrella by pressing down the cylinder, clamping the umbrella head by the umbrella handle clamping mechanism, clamping the umbrella sliding sleeve by the middle groove clamp, and changing the umbrella angle by two dual-axis rotation mechanisms, a secondary angle adjuster and an infrared sensor respectively, so that two industrial cameras can record the situations occurring during the opening and closing process of the umbrella, and perform detection and judgment, thereby realizing the opening and closing test of different types of umbrellas. However, the overall size of the middle groove fixture for the clamping part of the sliding sleeve is very large, which will block the shooting of the industrial camera and affect the fault handling and judgment. When the umbrella is closed or open, it will interfere with the umbrella surface and the ribs and cause damage. In addition, the middle groove fixture lacks a locking or pressing mechanism for the button on the sliding sleeve, and the opening and closing test of the hand-opened folding umbrella and the hand-opened straight-handled umbrella cannot be completed; and the dual-axis rotation mechanism and the secondary angle adjuster arranged on the three main mechanisms can only be adjusted to a certain angle, which is difficult to adapt to some smaller or larger sunny and rainy umbrellas; before the opening and closing test of each umbrella, manpower is required to analyze the current umbrella to adjust the parameters of each motor and cylinder and the relative positions of each mechanism to adapt to different types of umbrellas to ensure the stability of the test. The operation is cumbersome, the efficiency is low, and the degree of automation is not high; there is a lack of the function of measuring the opening and closing force of the umbrella and the compression force of the umbrella pole in the national standard and judging whether it is qualified.
[0004] There are many problems in the existing technology: 1. Most of the existing umbrella opening and closing equipment cannot adapt to all umbrella types on the market (hand-opened folding umbrellas, hand-opened straight-handled umbrellas, self-opening umbrellas, self-opening and self-closing umbrellas), and most of them can only be used for one or two types, with a small scope of application. 2. The existing umbrella opening and closing equipment lacks the function of measuring the opening and closing force and the compression force of the umbrella pole in the national standard "GB / T23147-2018 Sunny and Rainy Umbrella" 5.8, and judging whether it is qualified. 3. Most of the existing umbrella opening and closing equipment lacks the function of automatically identifying and judging whether a sunny and rainy umbrella has a fault during the opening and closing test. It can only manually determine whether the umbrella has a fault during the opening and closing test. Some use infrared sensors to detect whether the umbrella ribs are broken. The detection fault type is single, and the detection effect will be affected for umbrellas of different specifications and types. 4. Most of the existing umbrella opening and closing equipment uses pneumatic methods, such as cylinders, for driving devices for movements such as pressing the switch button, lifting and lowering the slide, fixing the umbrella tail, and compressing the umbrella pole. The control accuracy is low, and the speed and stroke are not easy to adjust. It is often necessary to manually adjust the position of each mechanism to adapt to umbrellas of different specifications and types. The operation is cumbersome and inefficient, and it is easy to cause excessive pressing of buttons and excessive compression of the umbrella pole, which affects the opening and closing test results. 5. The existing umbrella opening and closing equipment lacks the detection of the opening and closing stroke of the umbrella itself during the opening and closing test of the self-opening umbrella and the self-opening and self-closing umbrella. It is impossible to determine whether the umbrella is fully opened, and it is impossible to detect whether the spring of the self-opening umbrella and the self-opening and self-closing umbrella has failed. 6. Most of the existing umbrella head clamping devices use cylinders plus V-blocks for clamping, and the clamping effect is not ideal. The smaller the diameter of the umbrella head, the smaller the clamping force provided, and the worse the clamping effect. 7. Most of the existing umbrella sleeve clamping devices have large overall dimensions. When the umbrella is fully opened or closed, it is very easy to interfere with the umbrella cover and ribs. During the opening and closing test, as the number of times increases, it is easy to damage the umbrella, affecting the final test results. In addition, most of the existing umbrella sleeve clamping devices use manual clamping and are locked by screws, which is cumbersome to operate. 8. The existing umbrella sleeve clamping devices all use rigid clamping, which has a small contact area with the sleeve, has a poor clamping effect on the sleeve, and is difficult to adapt to sleeves of different shapes and sizes, and has a small range of adaptability. Summary of the invention

[0103] If the automatic umbrella to be tested is a folding umbrella, the umbrella will not be fixed.
[0104] D3, Open and close umbrella pole force measurement stage:
