A kind of copper-clad plate gluing drying equipment

Abstract

The utility model relates to the field of copper clad plate gluing and drying, especially to a copper clad plate gluing and drying device. It comprises a feeding roll, a material receiving roll and a drying box. A first gluing roller and a second gluing roller are horizontally arranged on one side below the feeding roll, and the first gluing roller and the second gluing roller extend into a gluing groove. The material receiving roll is arranged on one side above two limiting transmission rollers. Electronic glass fiber cloth is sequentially immersed in the gluing groove through the first gluing roller and the second gluing roller from the feeding roll. The feeding roll and the material receiving roll are driven to rotate by a motor. The device uses negative pressure to form an air duct for drying. The opening of the air outlet faces downward, and the arc-shaped air outlet guide surface on one side can make the air outlet larger, so that the air speed of the air duct is smaller. The air inlet groove is provided with multiple air inlets, and the shape of the air inlet groove is an arc that curves upward. Hot air that goes out of the air inlet groove will be guided to move obliquely upward. The multiple air inlets can not only prevent the hot air from being directly blown but also make the drying process more gentle.

Description

Technical Field

[0001] This utility model relates to the field of adhesive drying on copper-clad laminates, and more particularly to an adhesive drying device for copper-clad laminates. Background Technology

[0002] In the production of copper clad laminates, an important step is to apply adhesive to the electronic fiberglass cloth and then dry it. Previously, the drying method used was direct blowing with a fan. However, because copper clad laminates are very precise in subsequent processing, direct blowing combined with resistance wire hot air would result in uneven texture of the electronic fiberglass cloth. Therefore, based on this technical problem, we designed an adhesive drying device for copper clad laminates. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a copper-clad laminate adhesive drying device, including a feeding roll, a take-up roll, and a drying box; a first adhesive roller and a second adhesive roller are horizontally arranged on one side below the feeding roll, and the first adhesive roller and the second adhesive roller extend into the adhesive trough; two limiting transmission rollers are arranged above the second adhesive roller, and a take-up roll is arranged on one side above the two limiting transmission rollers; electronic fiberglass cloth passes sequentially from the feeding roll through the first adhesive roller and the second adhesive roller and is immersed in the adhesive trough, then passes vertically upward from one side of the second adhesive roller through the two limiting transmission rollers, and is retrieved by the take-up roll; the electronic fiberglass cloth between the second adhesive roller and the limiting transmission roller passes through the drying box, and both the feeding roll and the take-up roll are driven to rotate by a motor.

[0004] The drying chamber has a central drying zone for conveying electronic fiberglass cloth. Vertically arranged air outlet and air inlet slots are provided on both sides. An air heating slot connected to the lower air inlet slot is located on the side away from the drying zone. A resistance heating wire is installed in the air heating slot. The air inlet of the air inlet slot faces the drying zone. An air outlet is located on the lower side of the upper air outlet slot near the drying zone. A negative pressure fan is installed on the side of the air outlet slot away from the drying zone.

[0005] An arc-shaped air outlet guide surface is provided on the side wall of the air outlet side below the air outlet slot.

[0006] The air inlet troughs are all arc-shaped structures that curve upwards and to one side of the drying zone, and the hot air is guided to move obliquely upwards along the arc-shaped air inlet troughs.

[0007] The air heating tank has a through-hole on one side, and a grid plate is installed at the through-hole.

[0008] The beneficial effects of this utility model are as follows:

[0009] This device uses a negative pressure air duct for drying. The air outlet faces downwards, and the arc-shaped air outlet guide surface on one side makes the air outlet larger, thereby reducing the air velocity in the air duct. There are multiple air inlet slots, which are curved upwards. The hot air exiting from the air inlet slots is guided to move obliquely upwards. The multiple air inlet slots ensure that the incoming hot air is not blown directly but dries more gently. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0014] See Figure 1-2 .

[0015] This utility model discloses a coating and drying device for copper-clad laminates, including a feeding roll 1, a take-up roll 2, and a drying chamber 3. A first coating roller 4 and a second coating roller 5 are horizontally arranged on one side below the feeding roll. The first and second coating rollers extend into the coating trough 6. Two limiting transmission rollers 7 are arranged above the second coating roller. A take-up roll is arranged on one side above the two limiting transmission rollers. Electronic fiberglass cloth 8 passes from the feeding roll through the first and second coating rollers and is immersed in the coating trough. It then passes vertically upward from one side of the second coating roller through the two limiting transmission rollers and is taken back by the take-up roll. The electronic fiberglass cloth between the second coating roller and the limiting transmission rollers passes through the drying chamber. Both the feeding roll and the take-up roll are driven to rotate by a motor 9.

[0016] The drying chamber has a central drying zone 10 for conveying electronic fiberglass cloth. Vertically arranged air outlet slots 11 and air inlet slots 12 are provided on both sides. An air heating slot 13 is provided on the side of the lower air inlet slot away from the drying zone and is connected to it. A resistance heating wire 14 is provided in the air heating slot. The air inlet 15 of the air inlet slot faces the drying zone. An air outlet 16 is provided on the side of the upper air outlet slot near the drying zone. A negative pressure fan 17 is provided on the side of the air outlet slot away from the drying zone.

[0017] An arc-shaped air outlet guide surface 18 is provided on the side wall of the air outlet on one side below the air outlet slot.

[0018] The air inlet troughs are all arc-shaped structures that curve upwards and to one side of the drying zone, and the hot air is guided to move obliquely upwards along the arc-shaped air inlet troughs.

[0019] The air heating tank has a through-hole on one side, and a grid plate 19 is installed at the through-hole.

[0020] Specific operations

[0021] First, the resistance heating wire 14 and the negative pressure fan 17 are started. The motors of the feeding roll 1 and the take-up roll 2 are started to slowly drive the electronic fiberglass cloth 8 through the gluing tank 6 for gluing. After completion, it enters the drying chamber. The air from the air inlet slots 12 of the drying chamber moves obliquely upward to the drying area 10 by the negative pressure fan 17 in the air outlet slot 11, thereby drying the material. The hot air enters the air outlet slot 11 from the air outlet below the air outlet along the arc-shaped air outlet guide surface 18, and is then sent out by the negative pressure fan 17.
