Description

Technical Field

[0001] This application relates to the field of cosmetic pen testing, and more particularly to a cosmetic pen line shape testing device and equipment. Background Technology

[0002] In the cosmetics manufacturing industry, eyeliner, as a core tool for eye makeup, directly determines the drawing effect and user experience through its tip structure design and ink flow smoothness. Traditional eyeliner quality inspection methods mainly rely on manual operation and subjective judgment. Specifically, operators must hold the eyeliner and draw lines multiple times on specific paper materials, visually observing the uniformity of line thickness, edge sharpness, and the presence of ink breaks or smudging. This inspection method is not only inefficient but also significantly affected by individual visual differences, lighting conditions, and fatigue levels, easily leading to inconsistent evaluation standards. Especially when simulating real-world usage scenarios, the randomness of hand pressure angles and movement speeds is difficult to accurately reproduce, resulting in large fluctuations in test results for the same batch of products, making it impossible to form a quantitative evaluation basis. Furthermore, manual inspection struggles to capture the microscopic morphological characteristics of lines, such as forked strokes and ink deposition, directly affecting product pass rate determination and subsequent process optimization. As consumers' demands for sophisticated makeup tools increase, traditional inspection methods can no longer meet the requirements of modern production for efficiency, accuracy, and standardization.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0041] This application provides a cosmetic pen line shape detection device, which includes a mounting plate 100, a winding and unwinding assembly 200, a linear drive assembly 300, a traction wheel 400, and a vision detection assembly 500. Specifically, the winding and unwinding assembly 200 is used for unwinding and rewinding the drawing paper, and has an unwinding position and a rewinding position. The linear drive assembly 300 is mounted on one side of the mounting plate 100, and the traction wheel 400 is disposed at the moving end of the linear drive assembly 300. The linear drive assembly 300 is used to move around the drawing paper disposed on the outer circumference of the traction wheel 400 toward or away from the cosmetic pen. The vision detection assembly 500 is located between the traction wheel 400 and the rewinding position of the winding and unwinding assembly 200.

[0042] See Figure 1 and Figure 2 As shown, in the initial state, the paper used for drawing lines is located at the unwinding position of the unwinding assembly 200, and the paper is wound up by the unwinding assembly 200 after passing around the traction wheel 400. When it is necessary to detect the line shape drawn by the makeup brush, the linear drive assembly 300 first drives the traction wheel 400 to move towards the makeup brush position. During this process, the traction wheel 400 will pull the paper towards the makeup brush until it touches the tip of the brush. Then the winding position will rewind the paper, that is, the paper moves. For this purpose, the makeup brush will draw a line on the paper. Next, the visual detection assembly 500 will take a picture of the line shape for visual detection, so as to determine whether the line shape drawn by the makeup brush meets the requirements, thereby realizing the detection of the makeup brush line shape.

[0043] It should be noted that in this embodiment, the makeup pen is specifically an eyeliner pen, and the detection device should also include compatible electronic components such as a processor and a memory. For example, regarding how to determine whether the line shape meets the requirements, qualified line shape images can be stored in the memory. Then, the processor compares the line shape in the image captured by the vision detection component 500 with the standard qualified line shape image in the memory to determine whether the drawn line shape meets the requirements. Specifically, the lines from the image in the memory are compared with the lines from the image captured by the vision detection component 500 to see if they are consistent. If they are consistent, the makeup pen can be determined to be a qualified product; otherwise, it can be determined to be an unqualified product.

[0044] The unwinding and take-up assembly 200 includes an unwinding reel 210 and a take-up reel 220. The unwinding reel 210 is rotatably mounted on the mounting plate 100, and the take-up reel 220 is rotatably mounted on the mounting plate 100. The unwinding reel 210 and the take-up reel 220 are used for unwinding and rewinding the marking paper, respectively. A first rotary drive 221 for driving the take-up reel 220 to rotate is also mounted on the mounting plate 100.

[0045] Please continue reading. Figure 1 and Figure 2 As shown, both the unwind reel 210 and the take-up reel 220 are rotatably mounted on the side of the mounting plate 100, and the unwind reel 210 and the take-up reel 220 are located on the same side. Specifically, in order to enable the take-up reel 220 to take up the winding, a first rotary drive 221 is installed on the mounting plate 100. The first rotary drive 221 directly drives the take-up reel 220 to rotate to achieve winding. In practice, the position of the unwind reel 210 can be designed according to needs to determine whether a motor is needed to drive it to rotate for unwinding.

[0046] For example, the first rotary drive 221 can be a servo motor. Furthermore, since motors typically have the characteristics of high speed and low torque, in order to enable them to drive the take-up reel 220 to rotate, a suitable reducer can be installed at the output end of the servo motor to convert the high speed and low torque into a low speed and high torque state, thereby meeting the conditions for driving the take-up reel 220 to rotate.

[0047] The linear drive assembly 300 includes a sliding assembly 310 mounted on the mounting plate 100, a sliding plate 320 mounted on the sliding assembly 310, the sliding plate 320 being slidably connected to the mounting plate 100 via the sliding assembly 310, a linear drive member 330 for driving the sliding plate 320 to move being fixedly mounted on the mounting plate 100, and a traction wheel 400 being rotatably mounted on the sliding plate 320.

[0048] Please see Figure 1 , Figure 2 as well as Figure 3 As shown, in order to pull the paper toward the makeup brush, the linear drive assembly 300 needs to drive the traction wheel 400 toward the makeup brush. Furthermore, the linear drive component 330 drives the traction wheel 400 on the sliding plate 320 to move toward the makeup brush, thereby pulling the paper so that the paper can contact the tip of the makeup brush. In conjunction with the paper's winding motion, lines can be drawn on the paper.

[0049] Specifically, the sliding assembly 310 includes a guide rail 311 fixedly mounted on the side of the mounting plate 100, a slider 312 slidably mounted on the guide rail 311, and the slider 312 is fixedly connected to the sliding plate 320, thereby enabling the sliding plate 320 to slide relative to the mounting plate 100.

[0050] The visual inspection component 500 includes a stand plate 510, on which an inspection camera 520 is fixedly mounted, and a light source 530 is provided in the shooting direction of the inspection camera 520.

[0051] Please continue reading. Figure 1 and Figure 2 as well as Figure 7 As shown, in order to detect the lines drawn by the makeup brush on the paper, a visual inspection component 500 can be set on the winding path of the winding reel 220. Specifically, the inspection camera 520 of the visual inspection component 500 takes a picture of the lines on the paper, and then transmits the picture to the processor. The processor compares the picture with a standard line image stored in the memory to determine whether the line drawn by the makeup brush is qualified. For example, if the lines in the picture taken by the inspection camera 520 are consistent with the lines in the picture in the memory, the makeup brush is a qualified product; if the lines in the picture taken by the inspection camera 520 are inconsistent with the lines in the picture in the memory, the makeup brush is a defective product.

[0052] In this embodiment, in order to clearly capture the lines drawn on the paper, a light source 530 is installed in the shooting direction of the detection camera 520 to provide sufficient light for the shooting. Furthermore, the light source 530 is a coaxial light source, and the detection camera 520 is an industrial camera. The specific type can be selected as needed and is not limited here.

[0053] A rotary drive assembly 600 is provided on one side of the traction wheel 400. The rotary drive assembly 600 is located at the makeup brush position and is used to drive the makeup brush to rotate. The rotary drive assembly 600 includes a second rotary drive member 610. A transmission shaft 620 is provided at the rotation output end of the second rotary drive member 610. A drive wheel 630 is mounted on the transmission shaft 620.

[0054] Please see Figure 1 , Figure 2 as well as Figure 4 As shown, in order to detect the lines drawn by the tips of makeup brushes at multiple positions, a rotary drive assembly 600 is installed on the machine to drive the makeup brushes to rotate. Specifically, when the turntable rotates the rotating component containing the makeup brushes to the position of the rotary drive assembly 600, the drive wheel 630 will contact the outer surface of the rotating component. Next, the second rotary drive assembly 610 drives the drive wheel 630 to rotate through the transmission shaft 620, thereby driving the makeup brushes in the receiving holes of the rotating component to rotate. Thus, the tips of makeup brushes in different positions can draw lines on the paper, realizing the detection of line shapes.

[0055] In this embodiment, the second rotary drive 610 is a servo motor. Furthermore, the drive wheel 630 can undergo a certain deformation. When the drive wheel 630 contacts the rotary component, it can deform, thereby fully contacting the outer surface of the rotary component to achieve force transmission.

[0056] A tensioning assembly 700 is provided at the path between the unwinding position of the winding and unwinding assembly 200 and the traction wheel 400, and is mounted on the mounting plate 100. The tensioning assembly 700 includes a rocker arm 710 rotatably mounted on the mounting plate 100, and a tensioning wheel 720 is rotatably mounted on the rocker arm 710.

[0057] See Figure 1 , Figure 2 as well as Figure 5 As shown, in order to prevent the paper from wrinkling due to insufficient tension during anti-rolling, which would prevent the lines from being drawn completely on the paper and cause detection errors, a tensioning component 700 is set in the anti-rolling path to achieve paper tension.

[0058] Specifically, under the influence of gravity, the swing arm 710 will drive the tension wheel 720 to swing downwards and make contact with the paper surface at this position. As the swing arm 710 continues to drive the tension wheel 720 to swing downwards, the paper will move downwards to achieve tension and prevent the paper from wrinkling during the anti-rolling process.

[0059] A conveying assembly 800 is provided between the traction wheel 400 and the unwinding position of the take-up and unwinding assembly 200. The conveying assembly 800 is fixedly mounted on the mounting plate 100 with a third rotary drive 810. The output shaft of the third rotary drive 810 is equipped with a drive wheel 820. A driven wheel 830 is rotatably mounted on the mounting plate 100 at the position of the drive wheel 820.

[0060] See Figure 1 , Figure 2 as well as Figure 6As shown, in order to fully wind up the paper, a conveying component 800 is provided in the winding path between the traction wheel 400 and the winding reel 220. The conveying component 800 provides an initial pulling force for the paper winding, thereby facilitating the subsequent winding by the winding reel 220. Specifically, the paper passes through the area between the driving wheel 820 and the driven wheel 830, and the upper and lower surfaces of the paper contact the driving wheel 820 and the driven wheel 830 respectively. It can be understood that the driving wheel 820 and the driven wheel 830 clamp the paper. The third rotary drive 810 drives the driving wheel 820 to rotate and also drives the paper to be conveyed towards the winding reel 220, and also drives the driven wheel 830 to rotate. In this embodiment, the driving wheel 820 and the driven wheel 830 can be selected as elastic rollers, so that they can undergo a certain deformation to tighten and convey the paper.

[0061] The linear drive assembly 300 has two first guide wheels 110 rotatably mounted on both sides. The two first guide wheels 110 are respectively located on the path between the traction wheel 400 and the unwinding position of the take-up and unwinding assembly 200 and on the path between the traction wheel 400 and the take-up position of the take-up and unwinding assembly 200.

[0062] See Figure 1 and Figure 2 As shown, the paper transport path between the traction wheel 400 and the unwinding reel 210 is the unwinding path, and the paper transport path between the traction wheel 400 and the winding reel 220 is the winding path. In order to prevent the paper from curling to the traction wheel 400 and to be wound onto the winding reel 220 via the traction wheel 400, first guide wheels 110 are provided on both sides of the traction wheel 400. That is, the two first guide wheels 110 are respectively in the anti-curling path and the winding path. It can be understood that there should be a certain angle between the first guide wheel 110 in the unwinding path and the traction wheel 400, so that when the paper is pulled to the position of the makeup brush, the paper between the first guide wheel 110 in the unwinding path and the traction wheel 400 can contact the tip of the makeup brush.

[0063] Furthermore, the contact position between the paper and the makeup brush between the first guide roller 110 and the traction roller 400 in the unwinding path will vary depending on the height of the makeup brush tip. It can be understood that the paper between the first guide roller 110 and the traction roller 400 can contact the brush tip of different heights to draw lines.

[0064] See Figure 1 and Figure 2 As shown, the tensioning assembly 700 is provided with second guide wheels 120 on both sides. The second guide wheels 120 on both sides of the tensioning assembly 700 form a tensioning system for the paper. The second guide wheels 120 on both sides support the paper, and the tensioning assembly 700 presses down and tensions the paper under the action of gravity, thereby preventing the anti-rolling paper from wrinkling.

[0065] This application embodiment also provides a cosmetic pen testing device, which includes a turntable (not shown in the figure), a rotating component (not shown in the figure), and the cosmetic pen line shape testing device described in any of the above. Specifically, the turntable is rotatably mounted on the machine platform, and the turntable is provided with a plurality of workstation holes. The rotating component is rotatably disposed on the workstation holes, and the rotating component has a receiving hole for accommodating cosmetic pens. The testing device is disposed on the machine platform and located on one side of one of the workstation holes.

[0066] In this embodiment, the turntable is driven by a rotary drive device (not shown in the figure). The drive device can be composed of components such as a motor, reducer, and indexer to drive the turntable to rotate. In order to detect multiple cosmetic brushes, multiple workstation holes are opened on the turntable. Each workstation hole is provided with a rotating component (not shown in the figure). The rotating component can be composed of a bearing (not shown in the figure) and a rotating cylinder (not shown in the figure). The length of the rotating cylinder is greater than the axial thickness of the bearing, and the rotating cylinder has a receiving hole (not shown in the figure) for installing cosmetic brushes. The drive wheel 630 abuts against the outer wall of the rotating cylinder to drive the rotating cylinder to rotate, thereby driving the cosmetic brushes inside to rotate.

[0067] It is understandable that the inner wall of the receiving hole can come into contact with the makeup brush, thereby providing sufficient friction to drive the makeup brush to rotate. For example, a rubber pad layer can be provided on the inner wall of the receiving hole to achieve frictional transmission with the makeup brush.
