Description

Technical Field

[0001] The invention relates to a copper clad plate manufacturing technology, in particular to a glue dipping system. Background Art

[0002] As an indispensable material for the production of copper-clad laminates, electronic cloth is also a special basic material for the production of printed circuit boards. In recent years, it has been developing in the direction of becoming thinner and thinner. According to the thickness of electronic cloth, it can be divided into thick electronic cloth, thin electronic cloth, ultra-thin electronic cloth and ultra-thin electronic cloth (hereinafter referred to as "thick cloth, thin cloth, ultra-thin cloth, ultra-thin cloth"), as shown in the following table:

[0003] Product Name Thickness(μm) Commonly used IPC codes Ultra-thin cloth <28 1037 / 1027 / 1017 / 1000 / 101 / 1015 / 1007 Ultra-thin cloth 28—35 106 / 1067 / 1035 / 104 Thin cloth 36—100 1080 / 2116 / 1078 / 1086 Thick cloth >100 7628

[0004] In the existing dipping system, when dipping two types of glass fiber cloth with a large difference in thickness, it is necessary to stop the line first, lower the glue basin, and after dipping the glass fiber cloth, run the new glass fiber cloth idly to the metering wheel, then raise the glue basin to ensure that the glue liquid submerges the rubber roller before starting the line transmission production to ensure that static electricity does not produce sparks.

[0005] The existing dipping system, due to the discontinuous operation of the line, is prone to difficulty in tension control and easy cloth breakage and downtime when producing cloth types below 1027. The glass fiber cloth is prone to wrinkles during production, which destroys the apparent quality of the bonding sheet obtained after the glass fiber cloth is dipped in glue. The production stability is difficult to ensure and the production loss is very large.

[0006] In addition, the rubber roller of the existing dipping system is a through-shaft supporting bearing structure. When the dipping basin descends during cloth refilling, the rubber roller does not move. When the liquid in the basin is lower than the rubber roller, it is first separated from the liquid glue to refill the cloth. When the rubber roller leaves the liquid glue, the friction of the bearing is very large, so the bearing of the rubber roller is easily stuck, which especially causes the cloth surface to be torn during the refilling process when producing adhesive sheets with a thickness below 1027 cloth specifications.

[0007] In addition, in the existing dipping system, the bottom of the dipping basin is prone to sedimentation, which may easily lead to insufficient cloth hanging during dipping. Summary of the invention

[0064] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0065] Embodiment 1

[0066] like Figure 1 , Figure 2 As shown, the dipping system includes a glue basin 1 and a glue roller;

[0067] The rubber rollers include M fixed rubber rollers 21 and M movable rubber rollers 22, where M is a positive integer;

[0068] The M fixed rubber rollers 21 are fixedly arranged in the rubber basin 1 in a sequentially spaced manner and are located below the level of the glue liquid;

[0069] The M movable rubber rollers 22 are arranged in the rubber basin 1 in a sequential manner and can move up and down, wherein the first M-1 movable rubber rollers 22 are respectively arranged at the M-1 intervals of the M fixed rubber rollers 21, and the Mth movable rubber roller 22 is arranged at the rear side of the Mth fixed rubber roller 21;

[0070] The M movable rubber rollers 22 can move upward to above the level of the dipping liquid, and can move downward to below the two adjacent fixed rubber rollers 21;

[0071] The glass fiber cloth 9 to be dipped in glue is sequentially attached to the lower sides of the M movable rubber rollers 22 from front to back and dragged from front to back.

[0072] Preferably, the dipping system further comprises a controller; after the subsequent fabrication is completed, if the tension of the glass fiber cloth 9 is less than a set value, the controller controls the movable rubber roller to slowly descend to a set position in the glue solution to glue the glass fiber cloth.

[0073] In the glue dipping system of the first embodiment, the rubber roller is divided into a fixed position rubber roller 21 and a movable position rubber roller 22 that can move up and down. The movable position rubber roller 22 that can move up and down is in an upper position and away from the glue liquid surface when not in production or when re-clothing is being continued. After the re-clothing is completed, the movable position rubber roller 22 can automatically and slowly descend into the glue liquid to apply glue according to the tension data, and there is no need to stop the line in the middle.

[0074] When dipping glass fiber cloth Figure 1 As shown, M movable rubber rollers 22 move down into the glue liquid in the glue basin 1 and are respectively located under each adjacent fixed rubber roller 21. The glass fiber cloth 9 passes over the upper side of the i-th fixed rubber roller 21 and the lower side of the i-th movable rubber roller 22 from front to back in sequence, i being a positive integer less than or equal to M. The glass fiber cloth 9 is dragged from front to back for dipping. Figure 2 As shown, the glue basin 1 is fixed, and the M movable rubber rollers 22 move up to above the glue liquid in the foot basin.

After the glass fiber cloth is continued, the glue basin 1 is fixed and the M movable glue rollers 22 are moved down to below the dipping liquid level in the base basin. The line can work continuously during the continued laying of the glass fiber cloth, which is convenient for controlling the tension of the ultra-thin bonding sheet (for example, cloth types below 1027) when continued, improving the stability of the continued laying of the ultra-thin bonding sheet, avoiding cloth breakage and downtime due to stopping the line for continued laying, avoiding wrinkles of the glass fiber cloth during production, avoiding damage to the apparent quality of the bonding sheet obtained after the glass fiber cloth is dipped in glue, ensuring production stability, and reducing production losses.

[0081] Preferably, the dipping system further comprises an introduction roller 23;

[0082] The introduction roller 23 is fixedly arranged above the rubber basin 1 and is located in front of the frontmost fixed rubber roller 21;

[0083] The glass fiber cloth 9 that has been impregnated with glue is attached to the upper side of the introduction roller 23 .

[0084] The dipping system of the second embodiment is used to dipping the glass fiber cloth. Figure 1 As shown, the M movable rubber rollers 22 move down into the glue liquid in the glue basin 1 and are respectively located below the adjacent fixed rubber rollers 21, and the outlet rubber roller 24 moves down so that the lower part is located below the glue liquid level or the entire part is located in the glue liquid, and the glass fiber cloth passes around the upper side of the i-th fixed rubber roller 21, the lower side of the i-th movable rubber roller 22 and the lower side of the outlet rubber roller 24 from front to back in sequence, and the glass fiber cloth is dragged from front to back for dipping; when the glass fiber cloth is continued to be laid as shown in FIG. Figure 2 As shown, the glue basin 1 is fixed, and the M movable rubber rollers 22 and the outlet rubber roller 24 are moved up to the top of the glue liquid in the base. The outlet rubber roller 24 of the dipping system of the second embodiment can smooth the delivery angle of the glass fiber cloth after dipping, and is particularly suitable for the glue basin 1 whose cross section increases from bottom to top.

[0085] Embodiment 3

[0086] Based on the first embodiment, the dipping system further includes a vibration group 3;

[0087] The vibration group 3 is fixedly arranged at the bottom of the rubber basin 1;

[0088] The vibration group 3 is capable of vibrating.

[0089] The glue dipping system of the third embodiment can use a high-frequency pneumatic motor or other vibration source to drive the swing block of the vibration group to vibrate at high frequency, so that the glue liquid at the bottom of the glue basin 1 obtains a dynamic mixed flow state to prevent sedimentation and increase the glue coating amount and the wetting effect on the cloth surface.

[0090] Embodiment 4

[0091] Based on the second embodiment, the dipping system further includes a box 4 and a squeezing roller 5;

[0092] The rubber basin 1 and the rubber roller are both arranged in the box body 4;

[0093] The upper wall of the box body 4 is formed with a cloth outlet;

[0094] The squeezing roller 5 is located outside the upper wall of the box body 4 and directly above the cloth outlet;

[0095] The squeezing roller 5 is used to drag and squeeze the glass fiber cloth 9 sent out through the cloth outlet of the box body 4.

[0096] Embodiment 5

[0097] Based on the dipping system of the fourth embodiment, an air inlet 41 is formed on the upper wall of the box body 4;

[0098] Non-flammable gas (such as nitrogen, carbon dioxide, etc.) can be pressed into the box body 4 through the air inlet 41.

[0102] The glue dipping system of the fifth embodiment, when starting to refill the cloth, controls the non-combustible gas to be pressed into the box 4 through the controller (PLC (Programmable Logic Controller), DCS (Distributed Control System), or single-chip microcomputer) and controls the rubber rollers 22 and the rubber outlet rollers 24 to rise and leave the glue liquid, while the line body does not stop. When the cloth surface leaves the glue liquid surface, the cloth can be refilled without stopping the line body. Under the protection of non-combustible gas and LEL monitoring, the cloth can be refilled while preventing the generation of static sparks. After the cloth is refilled, the rubber rollers 22 and the rubber outlet rollers 24 are controlled to slowly descend and dip into the glue liquid. After the glass fiber cloth surface is completely immersed in the glue liquid, the controller can control to stop the non-combustible gas from being pressed in.

The core shaft 202 is fixedly connected to the inner ring of the bearing, and the roller body 200 is fixedly connected to the outer ring of the bearing, so that the core shaft 202 can rotate relative to the roller body 200, reducing the friction of the bearing itself (rotation of the outer ring of the bearing + friction of the inner ring fixed structure < rotation of the inner ring + friction of the outer ring fixed structure), avoiding the problem of bearing jamming, and facilitating disassembly and maintenance.
