Description
Technical Field
[0001] This utility model relates to the field of glass fiber coating technology, specifically to an electronic-grade glass fiber sizing agent coating device. Background Technology
[0002] Electronic-grade glass fiber is mainly used in the modern electronics industry, primarily in the form of electronic-grade glass fiber cloth, also known as electronic cloth. It is generally used on circuit boards, mainly multilayer printed circuit boards. Sizing agents prevent glass fiber wear and provide bundle and lubrication for the glass fibers. Sizing agents are essential for electronic-grade glass fiber. There are two methods for coating sizing agents: coating the glass fiber cloth and coating the glass fiber filaments. For electronic-grade glass fiber, only the method of coating the glass fiber filaments with sizing agents can be used. During the coating process, it is often necessary to prevent dust from getting in, so the coating needs to be carried out in a sealed or semi-sealed environment. However, it is inconvenient to add sizing agents when coating in this way.
[0003] In the prior art, Chinese patent CN215592944U discloses a glass fiber filament sizing agent coating device. This coating device uses a lifting plate and a pressure roller to press the glass fiber filament into the sizing tank for uniform coating, but the aforementioned technical problems still exist.
[0004] Therefore, the technical problem to be solved in this case is: how to facilitate staff to replenish the wetting agent. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an electronic-grade glass fiber sizing agent coating device. This coating device involves passing glass fiber filaments through the feed inlet into the housing, and pressing the glass fiber filaments into the sizing tank through a lifting unit. The sizing agent in the sizing tank coats the glass fiber filaments. Finally, the coated glass fiber filaments are conveyed out of the housing from the discharge outlet. During the coating process, in order to avoid dust and other contaminants from entering the sizing agent, the housing is generally in a semi-sealed state. At this time, the operator can move the sizing tank from inside the housing to outside the housing, and through the opening to the outside of the housing, the operator can easily replenish the sizing agent in the sizing tank.
[0006] The technical solution of this utility model is:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Please see Figure 1-6 An electronic-grade glass fiber sizing agent coating device includes a housing 1 and a lifting unit 2. The housing 1 has an inlet 11 and an outlet 12 on both sides along its length. The inlet 11 is used to allow glass fiber filaments to enter the housing 1. The housing 1 has an impregnation tank 3 containing an impregnating agent. The lifting unit 2 is connected to the housing 1 and is used to press the glass fiber filaments into the impregnation tank 3. The outlet 12 is used to transport the glass fiber filaments coated with the impregnating agent from inside the housing 1 to the outside. The housing 1 has an opening on one side along its width. The impregnation tank 3 is movably connected to the housing 1 and can move along the opening. One end of the impregnation tank 3 can move from the opening to outside the housing 1.
[0028] In practical applications, glass fiber filaments enter the housing 1 through the feed inlet 11 and are pressed into the impregnation tank 3 by the lifting unit 2, thereby coating the glass fiber filaments with the sizing agent. The coated glass fiber filaments are then conveyed outwards from the discharge outlet 12 of the housing 1. During the coating process, if the impregnation liquid in the impregnation tank 3 is consumed to the level below the lifting unit 2, causing the lifting unit 2 to fail to press the glass fiber filaments into the sizing state, the coating fails. Before this happens, the operator can adjust the impregnation... One end of the wetting tank 3 moves from inside the housing 1 through the opening to the outside of the housing 1 and replenishes the wetting agent into the wetting tank 3. When replenishing the wetting agent, the lifting unit 2 is always located inside the wetting tank 3, so replenishing the wetting agent will not affect the coating. It should be noted that a viewing window is provided on one side of the housing 1 along the direction in which the wetting tank 3 moves out, so that the inside of the wetting tank 3 can be observed. In this way, it is convenient for the staff to replenish the wetting agent, and the coating work does not need to be interrupted when replenishing the wetting agent, thus ensuring that the wetting agent can be continuously coated on the glass fiber filament.
[0029] Preferably, the housing 1 is provided with a slide rail 13, which is arranged along the width direction of the housing 1. The bottom of the immersion tank 3 is provided with a roller 31, which is rotatably connected to the slide rail 13. One end of the immersion tank 3 can be moved from inside the housing 1 to outside the housing 1 through the roller 31.
[0030] With the above design, the roller 31 and slide rail 13 make it easy for the operator to move the immersion tank 3 from inside the housing 1 through the opening to outside the housing 1. However, the connection between the immersion tank 3 and the slide rail 13 can also be a sliding connection. The rolling connection is only to avoid the wetting agent overflowing outside the immersion tank 3 due to inertia during the movement, thus wasting the wetting agent. When the lifting unit 2 presses down a sufficient distance, or when the liquid level of the wetting agent in the immersion tank 3 is low, a sliding connection can also be used. In this case, the roller 31 can be replaced with a slider.
[0031] Preferably, the slide rail 13 is provided with a first limiting block 131, which is used to prevent the roller 31 from rolling out of the housing 1 along the width direction of the housing 1. When the roller 31 contacts the first limiting block 131, the lifting unit 2 is located in the immersion tank 3 on the projection along the height direction of the immersion tank 3.
[0032] In the above design, when the operator moves the impregnation tank 3 from inside the housing 1 to outside the housing 1, the first limiting block 131 can limit the movement distance of the impregnation tank 3, thereby ensuring that one end of the impregnation tank 3 moves out of the housing 1, which makes it convenient for the operator to replenish the impregnating agent. It can also ensure that the lifting unit 2 is always inside the impregnation tank 3 and will not interrupt the coating. Due to the rolling connection, the inertia can be greatly reduced. Therefore, the impregnating agent in the impregnation tank 3 will not overflow out of the impregnation tank 3 due to inertia because of the first limiting block 131.
[0033] Preferably, the slide rail 13 is further provided with a second limiting block 132, which is used to prevent the roller 31 from rolling into the housing 1 along the width direction of the housing 1; when the roller 31 contacts the second limiting block 132, the immersion groove 3 is completely located inside the housing 1.
[0034] In the above design, the second limiting block 132 can prevent the impregnation tank 3 from moving into the housing 1. When the operator replenishes the impregnating agent and moves the impregnation tank 3 back into the housing 1, it will serve as a reminder to the operator when the second limiting block 132 contacts the roller 31. In addition, the second limiting block 132 can also ensure that one end of the impregnation tank 3 is located in the opening in this state, thereby ensuring the sealing effect of the housing 1 during coating.
[0035] As a preferred embodiment, a fastener can be provided on the housing 1, and a corresponding fastener mating part is provided on the side of the immersion tank 3 near the handle. The fastener and the fastener mating part can prevent the immersion tank 3 from rolling out of the housing 1 from the opening. It should be noted that the fastener and the fastener mating part can be set as a bolt. The fastener and the fastener mating part are not shown in the figure.
[0036] Preferably, the fixing plate is provided with a handle on the side away from the immersion tank 3.
[0037] The above design allows the handle to facilitate the operation of the fixing plate by the staff, thereby making it easier for the staff to move the immersion tank 3.
[0038] Preferably, the lifting unit 2 includes a drive cylinder 21, a support plate 22, and a pressure roller 23. The drive cylinder 21 is connected to the top inside the housing 1, and the output end of the drive cylinder 21 is connected to the support plate 22. The pressure roller 23 is connected to the side of the support plate 22 away from the drive cylinder 21. The pressure roller 23 is used to press the glass fiber filaments into the impregnation tank 3 for coating.
[0039] In the above design, the drive cylinder 21 can drive the support plate 22 to move down or up, and the support plate 22 drives the pressure roller 23 to move up or down. The pressure roller 23 can press the glass fiber filament into the impregnation tank 3, so that the glass fiber filament can be impregnated in the impregnating agent for coating. In particular, a groove can be provided on the pressure roller 23, and the glass fiber filament can be located in the groove, so as to better limit the glass fiber filament and prevent the glass fiber from falling off the pressure roller 23.
[0040] Preferably, the support plate 22 is provided with a connecting rod 221 on the side near the pressure roller 23, and the pressure roller 23 is provided with a rotating shaft 231 that passes through the pressure roller 23. There are two connecting rods 221. One end of the rotating shaft 231 is connected to one of the connecting rods 221, and the other end is connected to the other connecting rod 221. The pressure roller 23 rotates around the axis of the rotating shaft 231.
[0041] Through the above design, the pressure roller 23 can rotate around the axis of the drive shaft, thereby avoiding excessive friction between the pressure roller 23 and the glass fiber filament, and better protecting the glass fiber filament.
[0042] Preferably, a hot air duct 14 is provided on one end of the housing 1 near the discharge port 12, which is arranged along the width direction of the housing 1. A hot air blower 4 is provided on the side of the housing 1 away from the impregnation tank 3. The output end of the hot air blower 4 is connected to the hot air duct 14. A vent 141 is provided on the side of the hot air duct 14 near the impregnation tank 3.
[0043] In the above design, the hot air blown out by the hot air blower 4 enters the housing 1 through the hot air duct 14 and is blown out through the vent 141. The vent 141 is located on the side facing the impregnation tank 3, which can dry the glass fiber filaments coated with sizing agent and improve the drying efficiency. Specifically, the vent 141 in this embodiment can be set as a strip groove, the area of which is based on covering all the glass fiber filaments coated with sizing agent. It can also be set as a circular groove. If it is set as a circle, it is arranged in accordance with the number and position of the pressure rollers 23.
[0044] Preferably, guide wheels 15 are provided at both ends of the housing 1. The guide wheels 15 are respectively connected below the feed inlet 11 and below the discharge outlet 12. The guide wheels 15 are used to guide the glass fiber filaments into or away from the housing 1.
[0045] With the above design, the guide wheel 15 located below the feed port 11 can guide the glass fiber filaments into the housing 1, and the guide wheel 15 located below the discharge port 12 can guide the coated glass fiber filaments to the outside of the housing 1, and then transport them to the subsequent processes through the external conveying device.
[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
