Description of the Invention (I) Field of the Invention The present invention relates to a method for the quality control or detection of bristles. In particular, the use end of the bristles has a rounded tip. Among them, the image recognition or identification device records the parallel ends of multiple bristles, and the result of the sharpness of the tip of the bristles can be obtained through image analysis. The present invention also relates to the use of the bristles of a brush. The bristles are inspected in this manner, and a brush ' BACKGROUND OF THE INVENTION Currently, plastic bristles are made by cutting a continuous monofilament or monofilament thread into a desired length. In cutting procedures, it is often not possible to obtain a flat cutting surface that is perpendicular or inclined to the bristle axis, and objects often leave burrs at the cutting edges. Among the conventional natural bristles (US 74,560) ′ For brushes that are treated or used on sensitive surfaces, the ends of the bristles must be made into spherical ends. This can be further applied to general hard bristles. For hard bristles, several methods have been proposed for rounding the ends of bristles. The rounding procedure is mechanically honing (DE 4 4 25 231, DE 195 2 6 933, EP 7 3 6 270,

For 'processing', the bristles are placed in parallel, the ends of these bristles are flattened, and then the ends are rounded by honing. In this method, the honing force is applied uniformly to the individual bristles that are integrated, so that a uniform smooth surface is obtained on all the bristles. The uniform and smooth bristles can be offset from each other in the axial direction 'so that the ends of the bristles have random or stepped envelopes (E P 3 4 6 6 4 6). So far, '尙 has not been used as a method for detecting the ends of the bristles to determine whether it has been processed' or to what degree of sharpness. Knowing the sharpness of the bristle ends is of decisive importance for brushes that are handled or used on sensitive surfaces, especially toothbrushes 'textile brushes, sanding brushes, etc., so that when mass-produced brushes', brushes with substandard quality throw away. According to the conventional technique (D E 3 7 4 1 6 1 6), the individual bristles of the finished brush are spot-checked. To perform this inspection, a general camera is used, and its optical axis is inclined to the bristles at a great angle. In order to fully illuminate the inspection or control area of very small bristles and avoid interference caused by reflection, the bristles must be illuminated with vertical light. The aforementioned document 尙 does not suggest how to obtain a true image approaching the ends of individual bristles with its optical configuration. Effective results cannot be expected with this detection, because the entire processed surface of the bristle ends cannot be recorded, and the ends of the bristle bundles show different positions relative to the optical axis of the camera and thus produce different images.

Description of the invention 0) Summary of the invention The purpose of the present invention is to propose a method to obtain effective quality control of the bristles at the end of use after processing. According to the above description, the bristles are arranged side by side with the envelope in a certain direction, and the ends of the bristles form a flat covering surface. The ends of the bristles are surface-structured or colored in advance so that Contrast with the envelope, and then use the image recognition device to record the end envelope surface. This can be done with an optical camera, whose optical axis is perpendicular to the envelope surface and parallel to the bristles. In the method according to the invention, it is first ensured that the bristles are located at the same relative position and that the ends of the processed bristles are located in a single common plane. In the plan view, all the bristle ends form individual small surfaces in a uniform grid or grid. These individual small surfaces contrast with very flat bristle envelopes by their structure or color. When the orientation of the image recognition device corresponds to a flat envelope or a bristle axis, the photoelectric element captures a grid image of a small surface. When the ends form a complete hemisphere, the contours rounded in a semi-ellipse or conical shape have the same reflection characteristics and produce a uniform grid image. By comparing with the main image of the desired state, a comparison result of the quality and quantity of the molding quality of the bristles can be obtained. In addition to image comparison, any other electronic conversion and evaluation procedures can be used. When coloring the bristle ends, the quality can be immediately visually observed. The bristle ends or bristles that are not on a specific surface appear to interfere in the lattice image. You can define tolerances for the number of interference surfaces and define when finished products must be discarded. -------— In ^ illllll ^ i ------- (Please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210 X 297) Love) -6- A7

Better quality control is implemented before making the brush, where continuous monofilament or multi-monofilament thread is cut to a certain length, and the bristles are placed in parallel and the front end of the brush is cut to form a flat Bread. Next, the bristle ends are processed ', especially by honing and the like, to round the bristle ends. The quality control is then implemented at the same location, and can be implemented after being translated to another plane. 0 Assuming all the ends of the bristles are on the same plane, the method according to the invention can also be applied to the finished brush. The bristles can be combined into a bundle, or they can be individually fixed to the brush body. The photovoltaic method combined with the present invention is known to those skilled in the art. A reference exemplary method is disclosed in DE E 197 24 421, which describes a method for photoelectric measurement of plaque. In order to make the bristle ends contrast with the rest, you can color the bristle ends to make a contrast before testing. For example, the ends of the bristles can be dyed with a contrasting color by soaking or applying. According to another modification method of the present invention, the shaped end of the bristles can be further micro-ground after dyeing and before the quality control. If the comparison is made in a structured way, it is better to pre-grind the bristle end by mechanical honing, then implement the surface configuration, and then perform the inspection. In this case, the rough ends of the configuration are only slightly ground after image evaluation. Alternatively, bristles can also be generated from plastic materials. The size of this plastic material applies to Chinese national standards (CNSM4 specification (210 X 297 mm)) (Jing first read the precautions on the back before filling out this page).

Description of the invention ii) Selective color-reactive pigments, and the ends of the bristles are treated at the same time as before to change the color of the bristles. The most likely pigments to be used are those that change color in response to thermal or radiant energy. If the color reactivity of the pigment is reversible, the individual bristles have the same color before and after the quality control. However, 'in the case of permanent coloring, the color will remain on the bristles and the finished product of the brush' to provide consumers with a quality assurance, which means that they have passed the quality control inspection. According to a further use, the dye is placed inside the bristles, and the dye is distributed over the entire circular surface when the ends are shaped. The ends of the bristles dyed in this way can also be detected using the aforementioned photoelectric method. If dyeing or coloring is performed after forming the ends, the honing surface is applied to the end faces of the unprocessed bristles that are parallel to each other to perform pre-forming or configuration processing, so that these bristles can be subjected to a detection procedure later. Instead of this method ', the dye can be transferred to the end portion by applying it to the end portion with a disk parallel to the covering surface while maintaining the position of the bristles. This method ensures that the dyeing process is performed under the same forming geometry and dynamic conditions of the bristle ends. It can be easily integrated into the corresponding manufacturing process c | ii 〇 After testing and before testing with a disk parallel to the cladding surface, the shaped bristles can be micro-ground. According to the method of the present invention, an improvement can be made to apply heat or radiant energy to the end of the surface of the envelope when using a color-reactive pigment. Another preferred transformation method is characterized in that after testing, the bristles are axially moved away from each other so as to bring their ends into a predetermined contour envelope, and _'11 · ----- ^- ------ Order ----- 1 --- line.ί. {Jing first read the notes on the back and then fill out this page) Printed on paper standards applicable to Chinese national standards (CNS) A4 specification (210 X 297 mm) 8 A7 B7__ V. Description of the invention P) The treatment is performed while maintaining the relative distance from the brush. Therefore, even after the brush is made, the ends of the bristles are located in the contour plane, the contour can be curved or stepped, and quality control operations can still be performed, and still provide clear information about bristles of different lengths, such as Molding quality, surface ratio and number of bristles. The advantages of this invention are particularly significant if the bristles are tilted a predetermined angle to secure the bristles to the brush while the bristles are being moved, and the brush is completed in a dense, dense manner. At this point, all bristles are uniformly colored at their ends. If, according to the method of the present invention, the ends of the bristles are applied with a permanent surface color or combined color with a color-reactive pigment, the colored ends can be retained after quality control. These colored ends do not interfere when using a brush. The invention also provides a method for visualizing the degree of bristles wear and wear. When in normal use, the main wear part of the bristles is at the envelope near the end, which leads to the removal of the material and forms the shape of a cone. Removal of the envelope is accompanied by removal of the color. It can be used to indicate the state of wear when special chromaticity appears on the entire surface of the bristles. The invention also relates to a brush, especially a toothbrush, the bristles of which have shaped ends, especially round ends, and are characterized in that the shaped ends of the bristles are colored to contrast with the bristles envelope for visual Forming quality. In the case of good quality, the bristle ends have a uniform shape, and the bristle areas with contrasting colors present a uniform optical grid, so that the molding quality can not be displayed to the user.

Description of the invention from the detailed description of the preferred embodiment FIG. 1 shows a processing device for rounding the ends of the bristles. This device has a honing coat 2 '. This layer is driven by a cam mechanism 3, and two cams 4 and 5' are mounted and moved in the direction indicated by the arrow. The individual bristles 6 are closely combined to form a bristle bundle 7. The ends 8 of the bristles 6 are located on a flat envelope. With the support portion 9, the bristles 6 can be positioned 'so that the end covering surface of the bristles is parallel to the honing coating 2. The support portion 9 may also be a brush body, and the bristles 6 or a bundle of bristles 7 are fixed thereto. Translating in the direction of the arrow 10, the honing coating 2 is in contact with the bristle ends, and the bristle ends 8 are uniformly rounded by the movement of the disc 1. After processing, 'the supporting portion 9 having the bristle bundles 7 is sent to the program station of Fig. 2', where the same disc 11 as the disc 1 of Fig. 1 is provided. The dish 11 has a support layer 1 2 'for receiving a dye coating 13. The disc 11 and the supporting portion 9 move relative to each other in the direction of the arrow 14 until the dye covering 13 contacts the bristle end 8 and transfers the dye to the bristle end. Next, the support portion 9 having the bristle bundles 7 arrives at the detection station of Fig. 4, where the bristle 6 and the bristle bundles 7 are parallel to the optical axis direction of the photovoltaic device 15. The light shines in the direction of the bristles, as indicated by the arrows, and is reflected back from the formed bristle end 8. After calibration with reference mechanism 17, uniformly shaped ‘especially rounded bristles produce uniform cells in the image evaluation device 16’ and can be evaluated with a screen 18 or a printer 19. Figure 5 shows two bristles 20, which have fully rounded ends. The dye layer 2 2 applied by the device of Figure 2 or by dipping is evenly distributed in the rounding (please read the precautions on the back before filling in this page)----In-—-— — — — — — — I -12- A7 B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. The description of the invention 〇) on the end 2 1. The device of FIG. 4 records the image of the end 21 of the two bristles and reproduces it to form the image 23 of FIG. 6. It shows a uniform circular surface with selective gradient grayscale tones. Fig. 5 also shows the unfinished bristles, such as the chamfered surface with burrs produced when cutting the length 2 5. The raw bristles were dyed with the apparatus of FIG. 2. It can be seen from Fig. 6 that the surface image is distorted and enlarged compared with the circle. The same dyeing procedure is applied to the bristles 28 in FIG. 5, and it is assumed that the ends 29 thereof are conical when honing, so that the dye layer 30 is brought into a corresponding state. This bristle end produces the image 31 in Figure 6. Finally, Fig. 5 shows an unprocessed bristle 32, which has an inclined cut surface 3 3, and results in that only the deeper part has a dye layer attached. The photograph is shown as image 3 4 in FIG. 6. In the quality control procedure, the drawing 2 in FIG. 6 meets the quality standards. However, all the other drawings 27, 31, and 34 are not conforming to the standard drawing and are shown as interference in the photoelectric evaluation. surface. By setting the corresponding allowance, a level standard can be established, according to which you can decide whether to discard defective bristles or brushes. It is also possible to establish an appropriate surface ratio of the quality of the ends or the number of bristles. Instead of the dye of FIG. 2, the bristle ends 8 can be roughly leaned on the processing station of FIG. 1 'hence'. Although the final shape is obtained, these ends have a fairly obvious surface structure, which is different from the bristle envelope part. Reflection characteristics, which can be used for optical evaluation. After the quality control according to FIG. 3, the ends of the bristles are further finely ground. Figure 7 shows the bristles 35 processed at different ends. The bristles 3 5 The length of the front part 3 6 is conical and the ends are rounded 3 7 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) -13- (Please read first Note on the back then fill out this page) | Order! !! -Line I. A7 B7 V. Description of the invention (M). As described above, the rounded ends 37 are dyed and a dye coating 38 is attached. Different dyes and structures can be used on the cone area 36 in advance. Photoelectric evaluation provided a surface image 3 9. This type of bristles is used for toothbrushes and can be used especially to clean the cracks on the tooth surface. The dyed bristles according to the invention provide a further possibility of using a brush in which such bristles are mounted. Figures 8 and 9 show the complete bristles 40 with rounded ends 4 1. On the rounded end of the bristles 40, a dye coating 42 is present, and this coating 42 is tightly covered on the end. When a brush equipped with the bristles is used, the abrasion occurs from the bristle envelope to the end of the bristles, so that the dye coating 4 2 is gradually worn away and a sharp point 4 3 is formed. This can be used as an indicator of wear, on the one hand, to indicate the use of the bristles, and on the other hand, when the brushes need to be replaced.
