Description

Technical Field

[0001] The present invention relates to the technical field of laminate production equipment, and in particular to a conveying device and laminate gluing equipment. Background Art

[0002] In the processing of copper clad laminates, the glass fiber cloth rolls need to be impregnated with epoxy resin, dried, cut into sheets, and then laminated and pressed. The quality of the glass fiber cloth impregnated with epoxy resin directly affects the quality of the final product.

[0003] On the one hand, the traditional gluing device will cause a great change in the viscosity of the glue due to changes in the weather. In addition, the conventional gluing device only immerses the glass fiber cloth in the glue around the rotating roller and then outputs it, which makes it very difficult to control the coating amount of the glass fiber cloth. It is easy to cause uneven thickness of the sheet material due to insufficient and uneven gluing of the glass fiber cloth, affecting the quality of the copper clad laminate. Especially during the gluing process, there is only one set of guide rails immersed in the glue to be wound around, which makes it difficult to ensure that the glue is fully coated on the glass fiber cloth. Moreover, it is impossible to control the amount of glue scraped on the glass fiber cloth, affecting the quality of the glass fiber cloth impregnated with epoxy resin.

[0035] The glue applying assembly 2 comprises a support frame 201, a support shaft 202, a shaft sleeve 203, a glue squeezing roller 204, a glue applying roller 1 205, a glue applying roller 206, a guide roller 207, a glue groove 208, a glue storage box 209 and a fixed seat 210, wherein the bottom of the glue storage box 209 is installed on the fixed seat 210, the upper end of the glue storage box 209 is set as an open structure, the inside of the glue storage box 209 is set as a glue groove 208, the bottom side of the glue groove 208 is installed with a guide roller 207, the guide roller 207 is rotatably arranged in the glue storage box 209, a support frame 201 is arranged above the glue storage box 209, a support shaft 202 is rotatably arranged in the support frame 201, shaft sleeves 203 are arranged at both ends of the support shaft 202, and the shaft sleeves 203 are fixed on the support frame 201, so as to facilitate the support shaft 202 to be rotatably installed in the support frame 201;

[0036] In an embodiment of the present invention, the number of the support shafts 202 is three, wherein a rubber squeezing roller 204, a rubber application roller 205 and a rubber application roller 206 are respectively installed on the three support shafts 202. The rubber squeezing roller 204 and the rubber application roller 205 are arranged on the same side of the support frame 201 and are arranged in contact with each other, and the rubber application roller 206 is arranged on the other side of the support frame 201.

[0037] The gluing machine frame 1 includes a top plate 101, a lifting bracket 102, a guide column 103, a guide sleeve 104, a lifting slider 105, a lifting cylinder 106, a lifting piston rod 107, a motor seat 108, a servo motor 109 and a rotating shaft 110, wherein the lifting bracket 102 is installed at the upper end of the glue storage box 209, the top of the lifting bracket 102 is connected to the top plate 101, the lifting bracket 102 is composed of four guide columns 103, each guide column 103 is provided with a guide sleeve 104, a lifting slider 105 is connected between two guide sleeves 104 on the same side of the top plate 101, and the two lifting sliders 105 are located at both ends of the support frame 201;

[0040] The lifting piston rod 107 is driven to move by the lifting cylinder 106, driving the lifting slider 105 and the guide sleeve 104 to move up and down along the guide column 103, thereby adjusting the height of the support frame 201 and the upper glue roller 204, the first glue roller 205, and the second glue roller 206, so as to facilitate the immersion of the support frame 201 in the glue liquid or the lifting out of the glue liquid, and facilitate the adjustment of the height of the support frame 201;

[0041] Among them, by driving the rotating shaft 110 to rotate through the servo motor 109, the rotation angle of the support frame 201 can be adjusted, so as to facilitate the adjustment of the support frame 201 to be fully immersed or partially immersed in the glue liquid. Therefore, under the action of the guide roller 207 and the glue squeezing roller 204, the glue roller 1 205 and the glue roller 2 206 on the support frame 201, it is ensured that the glass fiber cloth is fully glued in the glue groove 208 of the glue storage box 209.

[0042] Example 2

[0043] The conveying device as described in Example 1 includes a laminated board gluing device and a conveying roller installed on the laminated board gluing device, wherein the conveying roller is installed on the upper side of the laminated board gluing device and is used to convey the glass fiber cloth.

[0044] The laminated board gluing equipment comprises a gluing frame 1 and a gluing assembly 2 , and the gluing frame 1 is installed on the gluing assembly 2 .

[0045] In the embodiments of the invention, see Figure 1 to Figure 4As shown, the glue scraping device on the laminated board also includes a scraper assembly 3, which includes a scraper fixing plate 301, a limiting hole 302, a limiting rod 303, a connecting block 304, a nut 305, a pressure adjusting screw 306, a limiting block 307, a spring 308, a scraper seat 309 and a scraper 310, wherein the scraper fixing plate 301 is installed at the bottom of the top plate 101 of the glue applying frame 1, and a limiting hole 302 is provided on the scraper fixing plate 301, and the limiting hole 302 is a waist-shaped hole, and a limiting rod 303 is slidably arranged in the limiting hole 302, and the limiting rod 303 is slidably arranged in the limiting hole 302. The rod 303 is fixed on the connecting block 304, and a nut 305 is fixed inside the connecting block 304. The nut 305 is threadedly connected to a pressure adjusting screw 306. The pressure adjusting screw 306 is vertically arranged, and the bottom of the pressure adjusting screw 306 is connected to a limit block 307. The limit block 307 is rotatably arranged in the slot of the scraper seat 309. A spring 308 is installed at the bottom of the scraper seat 309. The spring 308 is arranged on the scraper fixing plate 301 and is located between the scraper fixing plate 301 and the scraper seat 309, and is used to generate an upward elastic force on the scraper seat 309.

[0046] A scraper 310 is installed at the bottom of the scraper seat 309. The scraper 310 is located behind the glue squeezing roller 204 and the glue application roller 205 of the glue application component 2. The scraper 310 is arranged perpendicular to the glued glass fiber cloth and is located above the glue groove 208. When the glued glass fiber cloth is squeezed by the glue squeezing roller 204 and the glue application roller 205, the scraper 310 scrapes off the excess glue on the glass fiber cloth.

[0047] Preferably, a group of scraper components 3 are also provided on the bottom surface of the glass fiber cloth, and the scraper 310 of the scraper component 3 is against the bottom surface of the glass fiber cloth, so that both sides of the glass fiber cloth are scraped with glue, wherein the position height of the scraper seat 309 is adjusted by rotating the pressure adjustment screw 306 relative to the nut 305, thereby adjusting the distance between the scraper 310 and the glass fiber cloth, thereby controlling the amount of scraping glue.

[0048] Example 3

[0049] The conveying device as described in Example 1 includes a laminated board gluing device and a conveying roller installed on the laminated board gluing device, wherein the conveying roller is installed on the upper side of the laminated board gluing device and is used to convey the glass fiber cloth.

[0050] The laminated board gluing equipment comprises a gluing frame 1 and a gluing assembly 2 , and the gluing frame 1 is installed on the gluing assembly 2 .

[0051] In order to facilitate the rotation of the support frame 201 of the glue assembly 2, see Figure 1 to Figure 6As shown, a rotation adjustment mechanism 4 is installed on the rotation shaft 110 of the gluing machine frame 1, and the rotation adjustment mechanism 4 is located between the supporting frame 201 and the lifting slider 105. The rotation adjustment mechanism 4 includes a rotation adjustment box 401, a ratchet 402, a ratchet 403 and an electric push rod 404, wherein the rotation adjustment box 401 is fixed on the lifting slider 105, and the ratchet 402, the ratchet 403 and the electric push rod 404 are all installed in the rotation adjustment box 401, the ratchet 402 is installed on the rotation shaft 110, and the ratchet 403 is provided on the side of the ratchet 402, and the ratchet 403 is installed on the electric push rod 404, and the electric push rod 404 is arranged toward the ratchet 402, and the electric push rod 404 is fixed on the inner wall of the rotation adjustment box 401.

[0052] When it is necessary to adjust the angle of the support frame 201, the servo motor 109 drives the rotating shaft 110 to rotate, thereby driving the support frame 201 to rotate around the middle. At this time, the ratchet 403 is driven away from the ratchet 402 by the electric push rod 404, and does not contact the ratchet 402, and does not affect the rotation adjustment of the support frame 201 by the servo motor 109; when the support frame 201 rotates to a suitable position, at this time, the servo motor 109 pauses, and the electric push rod 404 starts and drives the ratchet 403 to move toward the ratchet 402 until the ratchet 403 is stuck in the tooth groove of the ratchet 402, thereby preventing the ratchet 402 from rotating, thereby ensuring that the rotation angle of the support frame 201 does not change, and the limiting effect is good, which facilitates the glass fiber cloth to be wound around the glue squeezing roller 204, the glue roller 1 205 and the glue roller 2 206 and to be glued.
