Description

Technical Field

[0001] The utility model relates to the technical field of electronic-grade glass fiber cloth production equipment, in particular to a sizing and warping device for ultra-thin electronic-grade glass fiber cloth. Background Art

[0002] Electronic cloth is made of glass fiber electronic yarn. Due to its high production technology and high product quality requirements, it is regarded as a high-tech product in the glass fiber series. Most electronic cloth is used to manufacture the insulating substrate of copper clad laminates and the adhesive sheet for multi-layer printed circuit boards. Its product performance directly determines the performance of copper clad laminates, so electronic cloth is closely related to electronic products.

[0003] As various electronic terminals downstream of PCB (such as mobile phones, computers, etc.) develop in the direction of "light, thin and short", the trend of thinning electronic cloth is relatively clear. The consumption of 7628 thick cloth in the global electronic cloth consumption structure continues to decrease, and the subsequent downward trend is expected to continue. Among electronic-grade glass fiber cloths, ultra-thin cloths have a high market share. During the production process of ultra-thin cloths, abnormal warp breakage and warp hairiness will occur. Abnormal warp breakage and warp hairiness will directly affect the surface quality of the electronic cloth, thereby affecting the performance and quality of the products of downstream copper clad laminate companies.

[0004] At present, most of the ultra-thin electronic cloth in the existing technology has four sizing axes and warp axes, and the 4-axis layering density is large and the number of heads is large. The workshop personnel cannot effectively intercept the warp abnormality. At the same time, the gap between each piece of the telescopic reed is larger than the gap at other positions, and the yarn density is uneven, resulting in the appearance of elastic warp. Utility Model Content

[0005] The purpose of the utility model is to provide a warp-and-spindle device for sizing ultra-thin electronic-grade glass fiber cloth. The warp-and-spindle device for sizing ultra-thin electronic-grade glass fiber cloth is provided with six branch shaft frames, so that the glass fiber yarn is unwound from the branch shaft frames, passes through the tension roller and enters the yarn threading platform for yarn threading. After the six-axis layering, the number of each axis head is small and the density is reduced. The workshop personnel can effectively intercept the warp abnormality, thereby reducing the warp abnormality of the electronic glass fiber cloth, thereby improving the appearance cloth quality of the electronic glass fiber cloth.

[0006] The utility model provides a warping device for ultra-thin electronic-grade glass fiber cloth sizing yarn, comprising glass fiber yarn, a split shaft frame and a yarn threading platform;

[0007] There are six branch shaft frames, each of which is provided with a tension sensing yarn guide roller;

[0008] The yarn threading platform is arranged on the outer side of the shaft frame;

[0009] The glass fiber yarn passes through the tension sensing yarn guide roller and then passes through the yarn distribution frame and enters the yarn threading platform for threading.

[0010] Preferably, a reed is provided on the yarn threading platform, with two yarns and one reed.

[0011] Further preferably, the reed is a machine head straight reed.

[0012] Further preferably, the yarn threading platform also includes a length measuring roller and a warp beam, and the length measuring roller and the warp beam are both arranged on the outside of the reed.

[0013] Preferably, the device is equipped with a laser electronic sensor.

[0014] Preferably, the yarn splitting frame comprises a frame body, and the frame body is provided with a yarn splitting rod.

[0015] Preferably, the six branch shaft frames are arranged horizontally in sequence.

[0016] Beneficial effects:

[0017] The technical solution of the utility model is to set up six branch axis frames, so that the glass fiber yarn is unwound from the branch axis frames, passes through the tension sensing yarn guide roller and enters the yarn threading platform for yarn threading. After the six-axis layering, the number of each axis head is small and the density is reduced. The workshop personnel can effectively intercept the warp anomaly, thereby reducing the warp anomaly of the electronic glass fiber cloth, thereby improving the appearance quality of the electronic glass fiber cloth.

[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] like Figure 1 As shown, the utility model provides a warping device for ultra-thin electronic grade glass fiber cloth sizing, which includes glass fiber yarn 1, a split shaft frame 6 and a yarn threading platform. Six split shaft frames 6 are provided, and each split shaft frame 6 is provided with a tension sensing yarn guide roller 4. The yarn threading platform is arranged on the outer side of the split shaft frame 6. After passing through the tension sensing yarn guide roller 4, the glass fiber yarn enters the yarn threading platform for yarn threading.

[0026] The technical solution of the utility model is to set up six branch shaft frames so that the glass fiber yarn 1 is unwound from the branch shaft frames, passes through the tension conduction sensing roller and then passes through the branch shaft frames 6 to enter the yarn threading platform for yarn threading. After the six-axis layering, the number of each axis head is small and the density is reduced. The workshop personnel can effectively intercept the warp anomaly, thereby reducing the warp anomaly of the electronic glass fiber cloth, thereby improving the appearance quality of the electronic glass fiber cloth.

[0027] A reed is arranged on the yarn threading platform, which is one reed for two yarns. The reed is a machine head straight reed 3. In the prior art, a design of one reed for four yarns is mostly adopted.

[0028] The yarn threading platform further comprises a length measuring roller 5 and a warp beam, and both the length measuring roller 5 and the warp beam are arranged on the outside of the reed.

[0029] The warping device is equipped with a laser electronic induction. In the prior art, the ultra-thin fabric weaving beam is worn with a dropper, but in this embodiment, the ultra-thin fabric weaving beam is not worn with a dropper, which can reduce friction. The device is also equipped with a laser electronic induction to prevent the yarn from breaking and not stopping.

[0030] The yarn splitting frame 6 comprises a frame body, on which a yarn splitting rod 2 is arranged.

[0031] The six branch axis frames are arranged horizontally in sequence.

[0032] The original production process of the ultra-thin cloth is 4-axis layering with a larger density and a larger number of heads. The 4-axis layering is changed to six-axis layering. After the six-axis layering, the number of heads per axis is smaller and the density is lower. For example: in the prior art, the number of heads is 888 for four axes, and in this embodiment, the number of heads is 592 for six axes, which can reduce yarn breakage during sizing and improve production efficiency, and avoid other abnormalities on the cloth surface caused by yarn breakage processing.

[0033] Working steps:

[0034] S1: Before production, set the sending tension and winding tension that match the fabric type.

[0035] S2: Change the original four warp beams into six warp beams and place them on the corresponding sending racks respectively.

[0036] S3: Through the traction of each roller, the warp yarn is unwound from each warp beam.

[0037] S4: Passing through each layering rod and layering reed, and then passing through the machine head straight reed 3, the original four yarns and one reed are changed to two yarns and one reed.

[0038] S5: The warp yarn is evenly wound onto the weaving beam according to the set production conditions of the cloth type to complete the warping.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
