Description

Technical Field

[0001] This invention belongs to the field of umbrella testing technology, specifically relating to an intelligent universal umbrella fatigue testing machine and its testing method. Background Technology

[0002] In the national standard GB / T 23147-2018 Umbrellas, the number of times the umbrella can be opened and closed, the force of the switch button, and the force of compressing the umbrella shaft are important indicators for judging whether the quality of the umbrella is qualified.

[0003] Current technologies include fixing the top of the umbrella with a pressing cylinder, clamping the umbrella head with a handle clamping mechanism, clamping the umbrella slide with a center groove clamp, and changing the umbrella angle through two dual-axis rotation mechanisms, a secondary angle adjuster, and an infrared sensor. This allows two industrial cameras to record and detect the opening and closing process of the umbrella, enabling testing of the opening and closing of different types of umbrellas. However, the overall size of the central slot clamp for the sliding sleeve is very large, which can obstruct the industrial camera's shooting and affect fault handling and judgment. When the umbrella is closed or open, it will interfere with the umbrella surface and ribs, causing damage. In addition, the central slot clamp lacks a locking or pressing mechanism for the buttons on the sliding sleeve, making it impossible to complete the opening and closing tests of manually opened folding umbrellas and manually opened straight umbrellas. Furthermore, the dual-axis rotation mechanism and secondary angle adjuster arranged on the three main mechanisms can only adjust a certain angle, making it difficult to adapt to some small or large umbrellas. Before testing the opening and closing of each umbrella, manual analysis is required to adjust the parameters of each motor and cylinder and the relative positions of each mechanism to adapt to different types of umbrellas and ensure test stability. The operation is cumbersome, inefficient, and lacks automation. It also lacks the function of measuring and judging whether the opening and closing force and the compression force of the umbrella pole as required by national standards.

[0004] The existing technology has several problems: 1. Most existing umbrella opening and closing devices cannot adapt to all umbrella types on the market (manually opened folding umbrellas, manually opened straight-handled umbrellas, self-opening umbrellas, and self-opening and self-closing umbrellas), and most can only be used for one or two types, resulting in a limited scope of application. 2. Existing umbrella opening and closing devices lack the function of measuring and determining the opening and closing force and the compression force of the umbrella pole as specified in section 5.8 of the national standard GB / T 23147-2018 Umbrellas. 3. The vast majority of existing umbrella opening and closing devices lack the function of automatically identifying and judging whether a fault has occurred during the opening and closing test of the umbrella. Faults can only be judged manually during the opening and closing test. Some devices use infrared sensors to detect whether the umbrella ribs are broken, but the detection type is limited, and the detection effect is affected by different specifications and types of umbrellas. 4. Existing umbrella opening and closing equipment mostly uses pneumatic methods, such as cylinders, for the drive devices of the switch button pressing, the sliding sleeve lifting, the umbrella tail fixing, and the umbrella pole compression. This results in low control precision, and the speed and stroke are not easily adjustable. It often requires manual adjustment of the positions of each mechanism to adapt to different umbrella specifications and types, making operation cumbersome and inefficient. This can easily lead to over-pressing of buttons and over-compression of the umbrella pole, affecting the opening and closing test results. 5. Existing umbrella opening and closing equipment lacks the ability to detect the opening and closing stroke of self-opening and self-closing umbrellas during the opening and closing test. It cannot determine whether the umbrella is fully opened, nor can it detect whether the springs of self-opening and self-closing umbrellas have failed. 6. Most existing umbrella head clamping devices use cylinders and V-blocks for clamping. The clamping effect is not ideal; the smaller the umbrella head diameter, the less clamping force is provided, and the worse the clamping effect. 7. Most existing umbrella slide clamping devices are large in overall size. When the umbrella is fully opened or closed, they are prone to interfering with the canopy and ribs. During opening and closing tests, with repeated use, they can easily damage the umbrella, affecting the final test results. Furthermore, most existing umbrella slide clamping devices rely on manual clamping and screw tightening, which is cumbersome. 8. Existing umbrella slide clamping devices all use rigid clamping, resulting in a small contact area with the slide, poor clamping effect, and difficulty in adapting to slides of different shapes and sizes, limiting their applicability. Summary of the Invention

[0005] To address the problems of existing umbrella opening and closing devices being unable to fully adapt to the opening and closing tests of all umbrella types specified in national standards, lacking the ability to test the opening and closing force and compression force of the umbrella pole as specified in national standards, lacking the function of automatically identifying and judging umbrella malfunctions, having low equipment versatility, low efficiency, and poor test results, an intelligent universal umbrella fatigue testing machine and its testing method are proposed.

[0020] The host computer is equipped with an algorithm for umbrella fault identification and detection.

[0021] II. A testing method for an intelligent universal umbrella fatigue testing machine

[0022] The testing methods include a fatigue testing method for a manual umbrella and a fatigue testing method for an automatic umbrella.

[0023] The fatigue testing method for the manual umbrella under test includes a handle fixing stage, an umbrella top fixing stage, an umbrella slide travel measurement stage, and an umbrella opening and closing cycle test stage; the fatigue testing method for the automatic umbrella under test includes a handle fixing stage, an umbrella top fixing stage, an opening and closing pole force measurement stage, an umbrella slide travel measurement stage, a compression pole force measurement stage, and an umbrella opening and closing cycle test stage.

[0024] The specific method for fatigue testing of the manual umbrella under test is as follows:

[0025] S1, Handle Fixing Stage: Control the grippers to hold and fix the handle of the manual umbrella to be tested.

[0026] S2, Umbrella Top Fixing Stage: If the manual umbrella under test is a straight-rib umbrella, the lifting rod is controlled to drive the umbrella top pressure head to press against the umbrella top; if the manual umbrella under test is a folding umbrella, the umbrella top is not fixed.

[0027] S3, Umbrella Slipper Stroke Measurement Stage: When the manual umbrella under test is opened, the control rack drives the flexible belt to align with the umbrella slipper, and the rotation of the control clamping gear one and clamping gear two drives the flexible belt to clamp the umbrella slipper. The position of the servo motor is the umbrella slipper opening position; the control rack drives the flexible belt to move the umbrella slipper downwards until the manual umbrella under test is closed. The position of the servo motor is the umbrella slipper closing position.

[0028] S4. Parachute opening and closing cycle test phase:

[0029] S41. Initialize the number of opening and closing loop tests.

[0030] S42, control the servo motor to move to the umbrella slide opening position.

[0031] S43. The camera takes a picture of the umbrella and transmits the picture to the host computer for umbrella fault identification and detection: if a fault is detected, the umbrella opening and closing cycle test ends; if no fault is detected, the servo motor is controlled to move to the umbrella slide sleeve to the umbrella closing position, thus completing one opening and closing cycle test and updating the number of opening and closing cycle tests.

[0032] S44. If the number of opening and closing cycle tests is greater than or equal to the preset opening and closing cycle test threshold, the umbrella opening and closing cycle test ends, and the manual umbrella under test is a standard umbrella. If the number of opening and closing cycle tests is less than the opening and closing cycle test threshold, repeat the above steps S42-S43 until the umbrella opening and closing cycle test ends.

[0033] The specific method for fatigue testing of the automatic umbrella under test is as follows:

[0034] D1. Handle fixing stage: Control the gripper to hold and fix the handle of the automatic umbrella under test.

[0035] D2. Umbrella Top Fixing Stage: If the automatic umbrella under test is a straight-rib umbrella, the lifting rod is controlled to drive the umbrella top pressure head to press against the umbrella top; if the automatic umbrella under test is a folding umbrella, the umbrella top is not fixed.

[0036] D3. Umbrella switch force measurement stage: When the control press head presses the umbrella switch button to open the automatic umbrella under test, the force sensor measures the button force as the opening force; when the control press head presses the umbrella switch button to close the automatic umbrella under test, the force sensor measures the button force as the closing force; after the press head is finished pressing, the electric push rod is returned to its original position.

[0037] D4. Umbrella Slipper Stroke Measurement Stage: When the automatic umbrella under test opens, the control rack drives the flexible belt to align with the umbrella slipper. The rotation of clamping gear one and clamping gear two drives the flexible belt to clamp the umbrella slipper. The position of the servo motor is the umbrella slipper opening position. The control rack drives the flexible belt to move downwards while clamping the umbrella slipper until the automatic umbrella under test closes. The position of the servo motor is the umbrella slipper closing position. The stroke measurement sensor measures the umbrella slipper stroke of the automatic umbrella under test.

[0038] D5. Compression Force Measurement Stage: If the automatic umbrella under test is a folding umbrella, the lifting rod is controlled to drive the umbrella top pressure head to press against the automatic umbrella under test. The position of the dual-axis motor is the starting position of the compression rod. The compression of the automatic umbrella under test continues until the automatic umbrella under test is closed. The position of the dual-axis motor is the ending position of the compression rod. During the compression process, the umbrella rod force sensor measures the compression force of the umbrella rod. After the compression is completed, the lifting rod returns to its original position. If the automatic umbrella under test is a straight-rib umbrella, the compression force of the umbrella rod is not measured.

[0039] D6. Parachute opening and closing cycle test phase:

[0040] D61. Initialize the number of times the parachute opens and closes in a loop test.

[0041] D62. Control the electric push rod to move to the umbrella opening button position; the stroke measurement sensor measures the travel of the umbrella sleeve of the automatic umbrella under test.

[0042] D63. If the umbrella slide travel of the automatic umbrella under test is less than the preset umbrella slide travel threshold, the umbrella opening and closing cycle test ends; if the umbrella slide travel of the automatic umbrella under test is greater than or equal to the preset umbrella slide travel threshold, the test continues.

[0043] D64. The camera takes pictures of the umbrella and transmits them to the host computer for umbrella fault identification and detection: If a fault is detected, the umbrella opening and closing cycle test ends; if no fault is detected, if the automatic umbrella under test is a folding umbrella, the dual-axis motor is controlled to move to the end position of the compressed umbrella rod. If the compressed umbrella rod force is greater than the preset compressed umbrella rod force threshold, the umbrella opening and closing cycle test ends; if the compressed umbrella rod force is less than or equal to the preset compressed umbrella rod force threshold, one opening and closing cycle test is completed, and the number of opening and closing cycle tests is updated; if the automatic umbrella under test is a straight-rib umbrella, the servo motor is controlled to move to the sliding sleeve closing position, one opening and closing cycle test is completed, and the number of opening and closing cycle tests is updated.

[0044] D65. If the number of opening and closing cycle tests is greater than or equal to the preset opening and closing cycle test threshold, the umbrella opening and closing cycle test ends, and the automatic umbrella under test is an umbrella that meets the national standard. If the number of opening and closing cycle tests is less than the opening and closing cycle test threshold, repeat the above steps D62-D64 until the umbrella opening and closing cycle test ends.

[0045] The beneficial effects of this invention are:

[0046] 1. This invention is applicable to various types of umbrellas, and is suitable for fatigue testing of four types of umbrellas: manual straight umbrellas, manual folding umbrellas, automatic straight umbrellas, and automatic folding umbrellas. This makes the invention widely applicable and of higher value.

[0047] 2. The present invention adopts motor drive for the driving devices of umbrella sleeve clamping, umbrella switch button pressing, umbrella top fixing and umbrella pole compression, which makes the overall control accuracy of the device more precise and the speed and stroke more convenient to adjust.

[0048] 3. The clamping structure of the umbrella slide and the umbrella handle adopted in this invention has a better clamping effect and more precise clamping control.

[0049] 4. In the fatigue test of automatic umbrellas, the present invention can still measure the travel of the umbrella slide to determine whether the umbrella is fully opened and whether the spring at the top of the umbrella pole has failed, thus solving the defects in the prior art.

[0050] 5. This invention also provides for measuring the force of the switch button and the force of the compressed umbrella pole, which solves the shortcomings of the prior art and brings about the advancement of umbrella fatigue testing technology in industry. Attached Figure Description

One end of the pressing head 51 extends into the interior of the other end of the electric push rod sleeve 54 and abuts against the other end of the force sensor 52. The other end of the pressing head 51 abuts against the umbrella switch button.

[0076] The intelligent universal umbrella fatigue testing machine also includes a camera, a host computer, and a PLC control system. The camera is installed in the middle of the frame 1 and arranged on one side of the umbrella opening and closing force measuring mechanism 5. It is used to photograph the inner surface of the umbrella after it is opened. The camera is electrically connected to the host computer. The PLC control system is electrically connected to the servo motor 224 of the drive component, the clamping motor 231 of the sliding sleeve clamping component, the cylinder 211 of the grip clamping component, the dual-axis motor 312 of the synchronous lifting compression component 31, the umbrella pole force sensor 321 of the umbrella pole force measuring component 32, and the electric push rod 53 of the umbrella opening and closing force measuring mechanism 5. The PLC control system is also communicatively connected to the host computer.

[0077] The host computer is equipped with an algorithm for identifying and detecting umbrella malfunctions.

[0078] Specific embodiments of the present invention are carried out according to the following detection methods:

[0079] The detection methods in the embodiments include a fatigue testing method for a manual umbrella under test and a fatigue testing method for an automatic umbrella under test.

[0080] The fatigue testing method for the manual umbrella under test includes the handle fixing stage, the umbrella top fixing stage, the umbrella slide travel measurement stage, and the umbrella opening and closing cycle test stage; the specific fatigue testing method for the manual umbrella under test is as follows:

[0081] S1, Grip Fixation Phase:

[0082] The canopy of the manual umbrella to be tested is fully opened and installed on the intelligent universal umbrella fatigue testing machine. The grip of the manual umbrella to be tested is clamped and fixed by controlling the grip clamping component 218 of the opening and closing mechanism 2.

[0083] S2, Umbrella Top Fixing Stage:

[0084] If the manual umbrella under test is a straight-rib umbrella, the lifting rod 311 of the synchronous lifting and compression assembly 31 is controlled to drive the umbrella top pressure head 323 to press against the umbrella top, so as to stabilize the umbrella top of the manual umbrella under test.

[0085] If the manual umbrella to be tested is a folding umbrella, then the top of the umbrella is not fixed.

[0086] S3, Umbrella Slipper Stroke Measurement Stage:

[0087] The PLC control system drives the rack 221 upward by controlling the servo motor 224 of the drive component, which in turn drives the flexible belt 236 upward, aligning the flexible belt 236 precisely with the umbrella slide sleeve. The PLC control system then controls the rotation of the clamping motor 231 of the slide sleeve clamping component, which in turn drives the clamping gear 233 and clamping gear 234 to rotate together, thereby tightening the flexible belt 236 and fully clamping the umbrella slide sleeve. The PLC control system records the position of the servo motor 224 as the umbrella slide sleeve opening position. The PLC control system then controls the rotation of the servo motor 224 of the drive component, which drives the rack 221 downward, which in turn drives the flexible belt 236 to clamp the umbrella slide sleeve downward, until the manual umbrella under test is closed. The PLC control system records the position of the servo motor 224 as the umbrella slide sleeve closing position.

[0088] S4. Parachute opening and closing cycle test phase:

[0089] S41. Initialize the number of opening and closing loop tests.

[0090] S42, the PLC control system controls the servo motor 224 of the drive component to move to the umbrella slide opening position, so that the manual umbrella under test is fully opened.

[0091] The S43 PLC control system transmits a photo-taking signal to the host computer, which then controls the camera to take a picture. The camera transmits the photo back to the host computer, which then performs umbrella fault identification and detection on the photo.

[0092] When a fault is detected, the host computer transmits an alarm and shutdown command to the PLC control system, the umbrella opening and closing cycle test ends, and the manual umbrella under test is marked as a faulty umbrella.

[0093] If the test shows no fault, the PLC control system controls the servo motor 224 of the drive component to move to the umbrella closing position, so that the flexible belt 236 drives the umbrella sliding sleeve to move downward, thereby making the manual umbrella under test close, which completes one opening and closing cycle test, and the number of opening and closing cycle tests is incremented by one.

[0094] S44. Determine whether the number of opening and closing cycle tests is greater than or equal to the preset opening and closing cycle test threshold:

[0095] If the number of opening and closing cycle tests is greater than or equal to the preset opening and closing cycle test threshold, the umbrella opening and closing cycle test ends, and the manual umbrella under test is marked as an umbrella that meets the national standard.

[0096] If the number of opening and closing cycle tests is less than the preset opening and closing cycle test threshold, repeat steps S42-S43 above until the umbrella opening and closing cycle test ends.

[0097] The fatigue testing method for an automatic umbrella under test according to an embodiment of the present invention is as follows:

[0098] The fatigue testing method for the automatic umbrella under test includes the handle fixing stage, the umbrella top fixing stage, the opening and closing force measurement stage, the umbrella sleeve travel measurement stage, the compression force measurement stage, and the umbrella opening and closing cycle test stage.

[0099] D1. Grip Fixation Stage:

[0100] The closed automatic umbrella to be tested is installed on the intelligent universal umbrella fatigue testing machine, and the gripper 218 of the handle clamping assembly of the opening and closing mechanism 2 is controlled to clamp and fix the umbrella handle of the automatic umbrella to be tested.

[0101] D2. Umbrella Top Fixing Stage:

[0102] If the automatic umbrella under test is a straight-rib umbrella, the lifting rod 311 of the synchronous lifting and compression assembly 31 is controlled to make the umbrella top pressure head 323 press against the umbrella top to stabilize the umbrella top of the automatic umbrella under test.

[0103] If the automatic umbrella under test is a folding umbrella, then the umbrella top is not fixed.

[0104] D3. Measurement of umbrella pole force during the switch operation:

[0105] Umbrella opening force measurement: The PLC control system controls the movement of the electric push rod 53 of the umbrella opening force measuring mechanism 5, which in turn drives the pressing head 51 to press the switch button of the automatic umbrella under test. The force sensor 52 measures the button force in real time. When the stroke measuring sensor 41 detects that the automatic umbrella under test suddenly opens, the button force measured by the force sensor is the umbrella opening force. The PLC control system records the position of the electric push rod 53 as the umbrella opening button position and controls the electric push rod 53 to retract to its original position.

[0106] Umbrella closing force measurement: The PLC control system controls the movement of the electric push rod 53 of the umbrella opening and closing force measuring mechanism 5, which in turn drives the pressing head 51 to press the opening and closing button of the automatic umbrella under test. The force sensor 52 measures the button force in real time. When the stroke measuring sensor 41 detects that the automatic umbrella under test suddenly closes, the button force measured by the force sensor is the umbrella closing force. The PLC control system records the position of the electric push rod 53 as the umbrella closing button position and controls the electric push rod 53 to retract to its original position.

[0107] D4. Umbrella Slipper Stroke Measurement Stage:

[0108] When the automatic umbrella under test opens, the PLC control system drives the rack 221 upward by controlling the transmission of the servo motor 224 of the drive component, which in turn drives the flexible belt 236 upward, so that the flexible belt 236 is aligned with the position of the umbrella slide sleeve. The PLC control system controls the rotation of the clamping motor 231 of the slide sleeve clamping component, which drives the clamping gear 1 233 and clamping gear 234 to rotate together, thereby tightening the flexible belt 236 so that the flexible belt 236 completely clamps the umbrella slide sleeve. The PLC control system records the position of the servo motor 224 as the umbrella slide sleeve opening position during the opening and closing cycle measurement stage. The PLC control system controls the transmission of the servo motor 224 of the drive component to drive the rack 221 downward, which in turn drives the flexible belt 236 to clamp the umbrella slide sleeve downward, so that the automatic umbrella under test closes. The PLC control system records the position of the servo motor 224 as the umbrella slide sleeve closing position during the opening and closing cycle measurement stage. The stroke measurement sensor 41 measures the umbrella slide sleeve stroke of the automatic umbrella under test.

[0109] D5. Measurement of compression parachute pole force:

[0110] If the automatic umbrella under test is a folding umbrella, the rotation of the dual-axis motor 312 of the synchronous lifting and compression assembly 31 drives the lifting rod 311 downward, which in turn drives the umbrella top pressure head 323 of the umbrella pole force measuring assembly 32 downward. When the umbrella pole force sensor 321 detects a change in the umbrella pole force as the umbrella under test compresses downward, the PLC control system records the position of the dual-axis motor 312 as the starting position of the compressed umbrella pole. The PLC control system continues to control the rotation of the dual-axis motor 312 of the synchronous lifting and compression assembly 31 to drive the lifting rod 311 downward, which in turn drives the umbrella top pressure head 323 of the umbrella pole force measuring assembly 32 downward. When the automatic umbrella under test is fully closed, the PLC control system records the position of the dual-axis motor 312 as the ending position of the compressed umbrella pole. The maximum value measured by the umbrella pole force sensor 321 during the compression process is taken as the compressed umbrella pole force. After compression is completed, the synchronous lifting and compression assembly 31 is controlled to return to its original position. If the automatic umbrella under test is a straight-rib umbrella, the compressed umbrella pole force is not measured.

[0111] D6. Parachute opening and closing cycle test phase:

[0112] D61. Initialize the number of times the umbrella opens and closes in a loop test.

[0113] D62, the PLC control system controls the electric push rod 53 to move to the umbrella opening button position, the umbrella surface is fully opened, and the stroke measurement sensor 41 measures the travel of the umbrella sleeve of the automatic umbrella under test.

[0114] D63. Determine whether the travel of the umbrella sleeve of the automatic umbrella under test is less than the preset umbrella sleeve travel threshold:

[0115] If the umbrella slide travel of the automatic umbrella under test is less than the preset umbrella slide travel threshold, the umbrella opening and closing cycle test ends and the automatic umbrella under test is marked as a faulty umbrella.

[0116] If the umbrella slide travel of the automatic umbrella under test is greater than or equal to the preset umbrella slide travel threshold, the test continues.

[0117] The D64 PLC control system transmits the image capture signal to the host computer, which then controls the camera to take a picture. The camera transmits the image back to the host computer, which performs fault identification and detection on the image.

[0118] When a fault is detected, the host computer transmits an alarm and stop command to the PLC control system. The umbrella opening and closing cycle test ends, and the automatic umbrella under test is marked as a faulty umbrella.

[0119] If the test shows no fault, and the umbrella under test is a folding umbrella, the PLC control system controls the dual-axis motor 312 to move to the end position of the compressed umbrella rod, and determines whether the compressed umbrella rod force is greater than the preset compressed umbrella rod force: if the compressed umbrella rod force is greater than the preset compressed umbrella rod force threshold, the umbrella opening and closing cycle test ends, and the umbrella under test is marked as a faulty umbrella; if the compressed umbrella rod force is less than or equal to the preset compressed umbrella rod force threshold, one opening and closing cycle test is completed, and the number of opening and closing cycle tests is incremented by one; if the umbrella under test is a straight-rib umbrella, the PLC control system controls the servo motor 224 of the drive component to move to the sliding sleeve closing position, and the umbrella under test completes the closure, thus completing one opening and closing cycle test, and the number of opening and closing cycle tests is incremented by one.

[0120] D65. Determine whether the number of opening and closing cycle tests is greater than or equal to the preset opening and closing cycle test threshold:

[0121] If the number of opening and closing cycle tests is greater than or equal to the preset opening and closing cycle test threshold, the umbrella opening and closing cycle test ends, and the automatic umbrella under test is marked as an umbrella that meets the national standard.

[0122] If the number of opening and closing cycle tests is less than the preset opening and closing cycle test threshold, repeat steps D62-D64 above until the umbrella opening and closing cycle test ends.
