Description

Technical Field

[0001] This invention relates to the field of reflective vest testing technology, and in particular to a long-distance reflective testing device and method for reflective vests. Background Technology

[0002] Reflective vests are core equipment for traffic safety and outdoor work protection. Their long-distance reflective performance directly affects the user's visibility in low-visibility environments, making it a key indicator for ensuring personal safety. Currently, long-distance reflective testing of reflective vests has become a necessary part of product factory inspection and industry quality supervision, requiring precise testing of core parameters such as reflective intensity and reflective uniformity in strict accordance with relevant national standards.

[0003] However, existing long-distance reflective vest testing equipment and methods still have many technical shortcomings, making it difficult to meet the needs of high-precision, multi-dimensional testing. Firstly, the fixing methods for reflective vests are unreasonable. Traditional methods such as clamping and binding with straps easily lead to wrinkles and displacement of the vest, making it impossible for the reflective strips to be accurately aligned with the test reference position, directly causing deviations in test data. Furthermore, the installation and positioning of the light source lack effective detection methods, relying solely on manual visual adjustment of the angle, which affects the objective evaluation of reflective performance. Secondly, the image acquisition dimensions are limited. Existing equipment's acquisition components are mostly fixed in height and angle, unable to achieve flexible adjustment across the entire horizontal range and multiple vertical heights, resulting in significant blind spots and making it difficult to comprehensively cover the reflective performance of all areas of the reflective vest.

[0004] These issues result in low testing accuracy of existing testing equipment, making it difficult to accurately reflect the actual long-distance reflective performance of reflective vests and hindering the provision of reliable data support for product quality assessment. Therefore, developing a long-distance reflective testing technology capable of precise vest fixation, efficient test posture calibration, and multi-dimensional image acquisition has become a pressing technical challenge for the industry. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention provides a long-distance reflective testing device for reflective vests, comprising a carrier plate and a test plate. The carrier plate holds a clothing mold, and the test plate holds a mirror mold that is symmetrical to the clothing mold. Both the clothing mold and the mirror mold are made of stainless steel and have reflective preset areas. The reflective vest is attached to the clothing mold via multiple magnetic patches. A light source is magnetically mounted in the reflective preset area of ​​the mirror mold. The test plate is equipped with a set of laser emitters, and the carrier plate is equipped with a laser aligner aligned with the laser emitters. The test plate is also equipped with a long-distance probe for detecting the distance to the carrier plate. Horizontal guide rails and lifting mechanisms that drive the horizontal guide rails are arranged on both sides of the test plate. The horizontal guide rails are equipped with a horizontal movement mechanism, and the horizontal movement mechanism is equipped with a horizontal distance probe for detecting the distance to the test plate. A micro servo motor is arranged on the top side of the horizontal movement mechanism, with the output end of the micro servo motor facing upward and connected to an image acquisition unit. The test plate is equipped with a horizontal distance detection component and a vertical distance detection component for detecting the installation position of the light source.

[0007] As a preferred technical solution of the testing equipment of the present invention: the carrier plate has a groove for mounting the clothing mold, the test plate has a groove for mounting the mirror mold, and the lower side of both the carrier plate and the test plate is equipped with an adjustment frame.

[0008] As a preferred technical solution for the testing equipment of the present invention: the reflective preset areas of the clothing mold and the mirror mold are mirror-symmetrical.

[0009] As a preferred technical solution of the testing equipment of the present invention: the transverse mechanism adopts a linear motor, the output end of the lifter faces upward and is connected to the lifting frame, and the transverse guide rail is installed on the top of the lifting frame.

[0010] As a preferred technical solution of the testing equipment of the present invention: the lateral distance probe is aligned with the installation position of the image acquisition device, a vertical reflector is set at the center of the back side of the test board, and the lateral distance probe of the lateral movement mechanism is aligned with the distance emission plate and monitors the distance of the reflector.

[0011] As a preferred technical solution of the testing equipment of the present invention: the power supply of the light source adopts a rechargeable type or an external power supply direct connection type, the light source is provided with a magnetic suction part, and the magnetic suction part is magnetically connected to the reflective preset area of ​​the mirror mold.

[0012] As a preferred technical solution of the testing equipment of the present invention: the lateral distance detection component is vertically arranged along the vertical side of the test plate, and multiple distance detection modules are sequentially arranged in the lateral distance detection component along the vertical direction. The vertical distance detection component is horizontally arranged along the top side of the test plate, and multiple distance detection modules are sequentially arranged in the vertical direction. The distance detection modules of both the lateral and vertical distance detection components face the mirror mold.

[0013] This invention provides a method for long-distance reflection testing of reflective vests, including the following:

[0014] Step 1: Mount the garment mold and mirror mold to the preset positions on the carrier plate and test plate, respectively.

[0015] Step 2: Attach the reflective vest to the garment mold using magnetic patches, ensuring that the reflective strips of the vest are precisely aligned with the preset reflective area.

[0016] Step 3: Set the preset distance between the carrier plate and the test plate according to the test standard, and monitor and fix their relative positions using a long-distance probe. Activate the laser emitter, adjust the attitude of the carrier plate and the test plate, and ensure the laser spot falls on the center of the laser alignment device to complete the calibration.

[0017] Step 4: Magnetically install the light source into the reflective preset area of ​​the mirror mold, ensuring that the light source is perpendicular to the reflective strip of the reflective vest.

[0018] Step 5: Detect the horizontal and vertical positions of the light source using the horizontal distance detection component and the vertical distance detection component, respectively.

[0019] Step 6: Start the lifting mechanism to drive the horizontal guide rail to rise and fall, so that the center height of the image acquisition unit and the light source unit are consistent.

[0020] Step 7: Start the lateral movement mechanism. The lateral distance probe monitors the distance in real time, and the micro servo motor drives the image acquisition unit to adjust the deflection angle.

[0021] Step 8: The image acquisition device collects reflective images in real time during the lateral movement, and the intensity and uniformity of the reflective light are analyzed later using professional software.

[0022] Compared with existing technologies, the beneficial effects of this invention are:

[0023] In this invention, the garment mold and the mirror mold adopt a mirror symmetrical design, and the reflective vest is fixed with magnetic patches, which can make the reflective strips and the pre-set reflective area accurately aligned, avoiding test deviations caused by vest displacement. At the same time, through the linkage design of the lifting device and the horizontal movement mechanism, and with the micro servo motor to adjust the angle of the image acquisition device in real time, this invention can realize full-dimensional image acquisition at different heights and different horizontal positions, covering the reflective performance of all areas of the reflective vest, and greatly reducing the test blind zone.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] Example 1: This invention designs a long-distance reflective testing device for reflective vests, including a main load-bearing component, a moving and lifting component, a detection and acquisition component, and a light source component. The specific structural configuration is as follows:

[0034] (a) Main load-bearing components

[0035] As shown in Figures 1 and 7, the loading plate 1 has a groove for holding the clothing mold 9a, and an adjustment frame 10 is configured on the lower side. A laser alignment device 101 aligned with the laser emitter 201 is mounted on the surface.

[0036] As shown in Figures 1 and 6, the test plate 2 has a groove for mounting the mirror mold 9b, an adjustment bracket 10 is configured on the lower side, a vertical reflector 202 is set in the center of the back side, and a set of laser emitters 201 and a long-distance probe 203 for detecting the distance of the carrier plate 1 are mounted on the surface.

[0037] As shown in Figures 1 and 2, the clothing mold 9a is made of stainless steel. The clothing mold 9a is equipped with a reflective preset area 901. The reflective vest 14 is attached to the clothing mold 9a by multiple magnetic patches 15. The reflective strips of the reflective vest 14 are aligned and matched with the reflective preset area 901.

[0038] As shown in Figures 1, 2, and 6, the mirror mold 9b is made of stainless steel and has a reflective preset area 901 that is mirror-symmetrical to the clothing mold 9a. The reflective preset area 901 is used to magnetically mount the light source 11.

[0039] (ii) Moving and lifting components

[0040] As shown in Figures 1, 4, and 5, the horizontal guide rail 3 is installed at the top of the lifting frame 7. The horizontal guide rail 3 is equipped with the horizontal movement mechanism 4, and the horizontal guide rail 3 provides a horizontal movement track for the horizontal movement mechanism 4.

[0041] As shown in Figures 1 and 2, the transverse movement mechanism 4 can be a linear motor. A transverse distance probe 401 is installed on the back side of the transverse movement mechanism 4 (aligned with the installation position of the image acquisition device 6), and a micro servo motor 5 is configured on the top side of the transverse movement mechanism 4.

[0042] As shown in Figures 1 and 5, a horizontal guide rail 3 is installed at the top of the lifting frame 7, and the output end of the lifting device 8 is connected to the lifting frame 7 with its direction upward. This device is used to drive the horizontal guide rail 3 to rise and fall, thereby adjusting the horizontal height of the image acquisition device 6.

[0043] (III) Detection and Acquisition Components

[0044] As shown in Figures 1 and 4, the image acquisition device 6 is connected to the upward-facing output end of the micro servo motor 5. Driven by the micro servo motor 5, its angle can be adjusted to detect and acquire light reflection images from the reflective vest 14. The micro servo motor 5, with its upward-facing output end connected to the image acquisition device 6, receives distance data and drives the image acquisition device 6 to deflect to a preset angle.

[0045] As shown in Figure 5, Figure 6 The horizontal distance detection component 12 is vertically set along the vertical side of the test plate 2. Multiple distance detection modules are arranged sequentially along the vertical direction of the horizontal distance detection component 12. All distance detection modules face the mirror mold 9b and are used to detect the horizontal distance position of the light source 11.

[0046] As shown in Figure 5, Figure 6 The vertical distance detection component 13 is horizontally arranged along the top side of the test plate 2. Multiple distance detection modules are arranged sequentially in the horizontal direction of the vertical distance detection component 13. All distance detection modules face the mirror mold 9b and are used to detect the vertical distance position of the light source 11.

[0047] like Figure 1The long-distance probe 203 is installed on the test plate 2 to monitor the preset distance between the carrier plate 1 and the test plate 2.

[0048] As shown in Figure 1, Figure 2 The lateral distance probe 401 is mounted on the lateral movement mechanism 4 and is aligned with the reflector 202 on the back side of the test plate 2. It is used to monitor the real-time distance between the lateral movement mechanism 4 and the test plate 2.

[0049] (iv) Light source assembly

[0050] As shown in Figure 1, Figure 2 The light source 11 is provided with a magnetic part 1101. The light source 11 is magnetically connected to the reflective preset area 901 of the mirror mold 9b through the magnetic part 1101. The power supply of the light source 11 is either rechargeable or directly connected to an external power supply. The light source 11 is vertically directed towards the reflective strip of the reflective vest 14.

[0051] Example 2: The long-distance reflectivity test method for the reflective vest designed in this invention is as follows:

[0052] (a) Preparation of magnetic patches and light source

[0053] Select 4-6 magnetic patches 15 (adjust the number according to the size of the reflective vest 14) and check their magnetic strength (e.g., the attraction force ≥ 5N, to prevent the vest from shifting during the test). If the light source 11 is rechargeable, ensure the power is ≥ 80% (confirm via the power indicator light on the light source 11). If it is directly connected to an external power supply, check that the power cord connection is secure to avoid power interruption during the test.

[0054] (ii) Positioning of the carrier plate and the test plate

[0055] According to the testing standard (such as GB20653 "Occupational High-Visibility Warning Clothing"), the preset distance L between the carrier plate 1 and the test plate 2 is set. s (Common settings: 50m, 100m, and 200m) Fix the carrier plate 1 and test plate 2 on the baseline at the preset positions. The long-distance probe 203 records the actual distance L between the carrier plate 1 and the test plate 2. s Adjust the positions of the carrier plate 1 and the test plate 2 according to the detected distance.

[0056] (III) Laser Alignment Calibration

[0057] Start the laser emitter 201 to emit a red collimated laser, and adjust the pitch and horizontal angles of the laser emitter 201 so that the laser spot falls completely on the center target of the laser alignment device 101.

[0058] (iv) Precise installation of the light source

[0059] Align the magnetic part 1101 of the light source 11 with the reflective preset area 901 of the mirror mold 9b, slowly approach until it is magnetically fixed, gently pull the light source 11 to confirm that it is firmly attached (without loosening or displacement), and direct the light from the light source 11 vertically toward the reflective strip of the reflective vest 14.

[0060] (v) Dual detection of light source position

[0061] The horizontal distance detection component 12, with its distance detection modules vertically distributed along the test plate 2, collects horizontal distance data from the light source 11. The average of three measurements is taken as the horizontal reference distance of the light source 11, denoted as L. x .

[0062] The vertical distance detection component 13, which is distributed along the top side of the test plate 2, collects the vertical distance data of the light source 11, and takes the average value as the vertical reference distance.

[0063] (vi) Adjustment of height and parameters synchronously

[0064] Based on the vertical reference distance of the light source 11 obtained by the vertical distance detection component 13, the lifting device 8 is activated, so that the lifting frame 7 drives the horizontal guide rail 3, the horizontal movement mechanism 4, and the image acquisition device 6 to rise and fall synchronously until they are consistent with the center height of the light source 11, and then the lifting device 8 is locked.

[0065] (vii) Synchronous collection of multi-dimensional data

[0066] After the lateral movement mechanism 4 is activated, one of the lateral distance probes 401 records the distance L between the lateral movement mechanism 4 and the back reflector 202 of the test plate 2 in real time. m1 Another lateral distance probe 401 records in real time the distance L between the lateral movement mechanism 4 and the back reflector 202 of the test plate 2. m2 Meanwhile, the micro servo motor 5 calculates the deflection angle of the image acquisition device 6 according to the following formula:

[0067] The image acquisition device, which is relatively close to the light source, deflects at an angle θ1 = arctan[L]. m1 -(L x -D / 2)] / L s .

[0068] The deflection angle θ2 of the image acquisition device, which is relatively far from the light source, is equal to arctan[L]. m2 +(L x -D / 2)] / L s Where D is the width of the test board.

[0069] The micro servo motor 5 drives the image acquisition device 6 to adjust its angle in real time, ensuring that the image acquisition device 6 is always aligned with the reflective strip area of ​​the reflective vest 14.

[0070] (viii) After the data collection is completed, all images are imported in batches through image analysis software. Unqualified images are automatically filtered out, and qualified images are analyzed and judged based on their reflectivity, reflectivity uniformity, etc.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
