Abstract
Description
Technical Field
[0001] This utility model relates to the field of tape coating, and in particular to a tape coating device with a coating detection mechanism. Background Technology
[0002] According to its function, tapes can be divided into high-temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure-sensitive tapes, and die-cut tapes. The surface of the tape is coated with an adhesive layer so that the tape can stick to the object. In the tape processing process, the adhesive needs to be applied to the substrate through coating equipment, and then dried, rolled up, and cut to complete the final tape roll.
[0003] When applying adhesive to a substrate, the substrate is usually immersed in the adhesive tank during transport and then dried. However, existing tape coating equipment requires checking the thickness and uniformity of the adhesive coating during the coating process. In contrast, existing tapes are usually dried directly during coating, or the operator makes a rough observation, which may lead to poor and inconsistent final tape quality.
[0004] Therefore, it is necessary to propose a tape coating equipment with a coating inspection mechanism to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a tape coating device with a coating inspection mechanism to solve the problem mentioned above where insufficient tape coating inspection affects tape quality.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a tape coating device with a coating and testing mechanism, comprising a coating machine and two coating frames for supporting the coating machine, wherein a testing frame is fixedly mounted on one of the coating frames, tape passes through the inside of the coating machine, a testing light array is fixedly mounted on the inner side of the testing frame, and multiple laser heads are fixedly mounted on the testing light array;
[0007] A focusing shell is fixedly provided on the inner side of the detection frame. The upper end of the focusing shell is inclined, and an entrance hole for the laser head light to enter is opened at the upper end of the focusing shell.
[0008] Two conical shells are fixed at both ends of the focusing shell, and a lux meter is installed at the end of each conical shell.
[0009] Preferably, a light-absorbing ring is fixedly provided on the inner side of the detection frame, the light-absorbing ring is arranged in a C shape, and two reflectors are fixedly provided on the inner side of the light-concentrating shell, with the light-absorbing ring located between the two reflectors;
[0010] The upper end of the reflector has multiple inclined reflective surfaces.
[0011] Preferably, the end of the conical shell has an observation port for individual observation.
[0012] Preferably, the laser head outputs a red beam of light.
[0013] Preferably, the plurality of laser heads are arranged in a linear array.
[0014] Preferably, the inner side of the light-absorbing ring is coated with black paint.
[0015] Preferably, both the reflective surface and the inner wall of the conical shell are mirror-like.
[0016] The technical advantages of this invention are as follows: By setting up multiple laser heads and utilizing the principle of beam irradiation, when the adhesive surface is flat, the red laser beam will irradiate vertically downwards; when the adhesive surface is uneven, the red laser beam will be refracted due to contact with the irregular surface, causing the red laser beam to tilt, thus indicating the quality of adhesive application on the tape. The light-absorbing ring facilitates the absorption of the normal red laser beam during detection. The inner side of the light-absorbing ring is coated with black paint, which has light-absorbing properties, reducing the brightness of the vertically irradiated red laser beam and allowing observation of the refracted red laser beam located outside the light-absorbing ring. Through the setting of the reflective surface and conical shell, after the red laser beam is refracted, it will irradiate the reflective surface on the reflector plate. Utilizing the angle of light refraction, it will be refracted again into the conical shell. After multiple refractions, the red laser beam reaches the vicinity of the illuminance meter. The illuminance meter detects the strong light and triggers an alarm, providing automated prompts for practical use. Attached Figure Description

[0023] like Figure 1 - Figure 5 As shown, this utility model provides a tape coating device with a coating detection mechanism, including a coating machine 1 and two coating frames 2 for supporting the coating machine 1. The coating machine 1 consists of multiple parts, including a frame, a transmission system, a control box, a coating head, a feeding system, a drying system, a winding and unwinding device, and a tension and correction system. Some parts are not shown in the figure and are existing technology, so they will not be described in detail here. The coating machine 1 is equipped with a tape 3. The tape 3 is connected to the coating head through the transmission system to apply adhesive. The feeding system is located at the upper end of the coating frame 2 and contains molten adhesive. The tape 3 enters the adhesive and is then taken out. It is dried by the drying system to carry out the production process. The production process is existing technology and will not be described in detail here.
[0024] Existing tapes and adhesives are often transparent, allowing light to pass through. Transparent tapes and adhesives are common technologies and will not be discussed in detail here. The quality of the adhesive application immediately after the adhesive is applied directly affects the overall quality of the tape, so it is necessary to inspect the adhesive application quality at this step.
[0025] One of the coating racks 2 is fixedly equipped with a detection rack 4. Inside the detection rack 4, a detection lamp array 5 is fixedly installed. Multiple laser heads 6 are fixedly installed on the detection lamp array 5. The operator turns on the detection lamp array 5 to turn on the multiple laser heads 6, so that the laser heads 6 work. The laser head 6 outputs a red beam of light. The multiple laser heads 6 are arranged in a linear array to ensure that the distance between any two corresponding red laser beams is equal. The red laser beam will pass through the transparent tape and glue and shine downward. When the glue surface is flat, the red laser beam will shine vertically downward. When the glue surface is uneven, the red laser beam will be refracted due to contact with the irregular surface, and the red laser beam will tilt. This allows us to know the coating quality of the glue on the tape.
[0026] A focusing shell 7 is fixedly installed inside the inspection frame 4. The upper end of the focusing shell 7 is inclined to facilitate close contact with the tape. A light inlet 8 is provided at the upper end of the focusing shell 7 for the light from the laser head 6 to enter, allowing the red laser beam to enter the interior of the focusing shell 7. A light-absorbing ring 9 is fixedly installed inside the inspection frame 4. The vertically irradiated laser beam will enter the interior of the light-absorbing ring 9. The light-absorbing ring 9 is C-shaped to facilitate the absorption of the normal red laser beam during inspection. The inner side of the light-absorbing ring 9 is coated with black paint. Black paint is existing technology and will not be described here. Without going into too much detail, black has light-absorbing properties, which helps to reduce the brightness of the vertically irradiated red laser beam. To observe the red laser beam refracted outside the light-absorbing ring 9, two reflectors 10 are fixedly installed inside the focusing shell 7, and the light-absorbing ring 9 is located between the two reflectors 10. Two conical shells 12 are fixedly installed at both ends of the focusing shell 7. The ends of the conical shells 12 have observation ports 14 for individual observation. The operator can observe the refracted light inside the focusing shell 7 through the observation ports 14. This method of observing the coating quality is accurate and fast.
[0027] The upper end of the reflector 10 has multiple inclined reflective surfaces 11. Both the reflective surfaces 11 and the inner wall of the conical shell 12 are mirrored to facilitate the refraction of the red laser beam. The reflective surfaces 11 are inclined to facilitate the refraction of the red laser beam using the principle of pipeline refraction. Each reflective surface 11 has a different inclination angle to facilitate the refraction of the red laser beam into the conical shell 12 from different positions. An illuminance meter 13 is installed at the end of the conical shell 12. The illuminance meter 13 is existing technology and is mainly used to observe brightness, so it will not be described in detail here.
[0028] After the red laser beam is refracted, it will shine on the reflective surface 11 on the reflector 10. Utilizing the angle of light refraction, it will be refracted into the interior of the conical shell 12. After the red laser beam is refracted, it will undergo multiple refractions and reach the vicinity of the illuminance meter 13. The illuminance meter 13 detects the strong light and issues an alarm for automated prompting, which is convenient for practical use.
