Description

Technical Field

[0001] The present invention relates to the technical field of copper clad laminate processing, and particularly relates to a glue coating device and method for copper clad laminates. Background Art

[0002] Copper clad laminate is a sheet material made by impregnating electronic glass fiber cloth or other reinforcing materials with resin, and covering one or both sides with copper foil and then hot pressing. It is simply called copper clad laminate. Various printed circuit boards with different forms and functions are processed, etched, drilled, and copper plated selectively on the copper clad laminate to form different printed circuits. It mainly plays the roles of interconnection conduction, insulation, and support in the printed circuit board, and has a great influence on the signal transmission speed, energy loss, characteristic impedance, etc. in the circuit. Therefore, the performance, quality, processability, manufacturing level, manufacturing cost, long-term reliability, and stability of the printed circuit board largely depend on the copper clad laminate. The glue used for gluing the copper clad laminate is usually a two-component epoxy resin glue, which mainly consists of resin and curing agent. The performance of the glue directly affects the quality and reliability of the circuit board.

[0003] When the existing glue coating device is in use, the curing agent needs to be mixed into the resin and stirred evenly to obtain the glue. Since gas is introduced during the stirring process of the raw materials, bubbles are generated. If the bubbles in the glue are not completely removed, bubbles will be generated after curing, and there will be many pinholes on the surface of the copper clad laminate after drying, seriously affecting the product quality. At the same time, during the glue coating process, the excess glue flows and drops on the copper clad laminate, resulting in waste. Summary of the Invention

[0007] In a preferred embodiment, a circular hole two is formed in the reciprocating slide, and a rotating shaft one is connected to the inside of the circular hole two through a bearing. A rotating circular plate is fixedly connected to the outer part of the rotating shaft. A circular hole three is formed at a position away from the center of the rotating circular plate, and an eccentric shaft is connected to the inside of the circular hole three through a bearing. The eccentric shaft and the rotating shaft one are movably connected to the same reciprocating push-pull frame. A rotating long column is fixedly connected to one end of the rotating shaft, and extrusion springs are fixedly connected to multiple sides of the rotating long column at equal intervals. The other ends of the multiple extrusion springs on the same side are all fixedly connected to the same scraping plate.

[0008] In a preferred embodiment, a power generation box is fixedly connected to one end of the hollow rotating tube, and the power generation end of the power generation box is connected to the inside of the stirring rod through a conductive hose.

A discharge hole is formed on one side of the collection pool, and a collection pipe is fixedly connected to the inside of the discharge hole. A discharge port is formed on the side of the mixing barrel, and a discharge pipe is fixedly connected to the inside of the discharge port. A valve is connected to the outside of the discharge pipe through a flange. Two sealing covers are movably connected to the mixing barrel.

[0010] By setting up a processing module, when the raw materials in the mixing barrel are being stirred and mixed, at this time, the power generation box is started. The power generation box conducts electricity to the stirring rod at the bottom of the reciprocating slide through a conductive hose, so that the conductive needles on the conductive spheres outside the stirring rod electrically shock and eliminate the bubbles generated during the mixing and stirring process. At the same time, the driving motor is started, and the driving motor drives the rotating support rod on the hollow rotating tube to move in a circle. At this time, the stirring rod moves in a circle. At the same time, the linkage gear at one end of the rotating support rod rotates self - driven under the limit of the limit circular tooth frame, so that the rotating shaft drives the eccentric shaft on the rotating circular plate to drive the reciprocating slide to move back and forth in the slideway on the rotating support rod, so that the conductive needles on the conductive spheres at the bottom of the reciprocating slide evenly eliminate the bubbles in the mixing barrel. At the same time, during the rotation of the rotating shaft, the scraper on the compression spring on the rotating long column scrapes the raw materials adhering to the inner wall of the mixing barrel, so that the raw materials are fully mixed, improving its use effect. During the gluing process of the copper - clad laminate, at this time, the excess flowing glue is collected by the collection pool on the tooling rack. At the same time, the heating box is started to heat the electric heating plate through the electric wire, so as to facilitate the collection of the glue in the collection pool into the mixing barrel. Through the processing module, the bubbles generated by the gas brought in during the stirring of the raw materials are eliminated, avoiding the incomplete removal of the bubbles in the glue, which will cause bubbles after curing, and there will be many pinholes on the surface of the dried copper - clad laminate, seriously affecting the quality of the product. At the same time, during the gluing process, the excess glue flowing down on the copper - clad laminate is collected and utilized to avoid waste.

[0011] In a preferred embodiment, an averaging module is provided on the tooling rack, and the averaging module includes triangular support plates. Circular holes four are formed on the sides of both triangular support plates. Rotating cylinders are connected to the interiors of the two circular holes four through bearings.

[0012] In a preferred embodiment, a groove is formed on the tooling rack, and the two sides of the groove are connected to the same rotating shaft two through bearings. A T - shaped linkage rack is fixedly connected to the exterior of the rotating shaft two. The toothed block end of the T - shaped linkage rack meshes with the bidirectional gear. A slideway is formed on the side of the T - shaped linkage rack. A fixed seat is fixedly connected to the tooling rack. A servo motor is fixedly connected to the side of the fixed seat. A rotating push rod is fixedly connected to the driving end of the servo motor. A circular hole five is formed on one side of the rotating push rod. A roller is connected to the interior of the circular hole five through a bearing, and the roller slides inside the slideway.

[0013] By setting an averaging module, during the gluing process of the copper clad laminate, at this time, the hollow roller on the gluing component is used to perform multi-directional gluing on the copper clad laminate. Meanwhile, the servo motor is started, and the roller on the rotating push rod is driven by the servo motor to move within the slideway of the T-shaped linkage rack, so that the toothed block end of the T-shaped linkage rack moves reciprocally, thereby causing the T-shaped linkage rack to drive the bidirectional gear to drive the rotating cylinder, making the copper clad laminate on the tooling bracket swing left and right. Thus, when the hollow roller contacts the copper clad laminate for gluing, the glue can be evenly spread on one side of the copper clad laminate, avoiding uneven coating.

[0014] In a preferred solution, a same clamping module is provided on the opposite sides of the two tooling brackets. The clamping module includes a limiting round rod and a clamping seat. Two nut sliders are slidably connected to the outside of the two limiting round rods. Six circular holes are opened on the sides of the two tooling brackets. The inside of the two circular holes six is connected by a bearing to a same bidirectional screw rod. A screw rod motor is fixedly connected to the side of one of the tooling brackets. The driving ends of the screw rod motor and one end of the bidirectional screw rod are both fixedly connected with a second pulley.

[0015] In a preferred solution, tooling plates are bolted to both of the nut sliders. Seven circular holes are opened on the sides of the two tooling plates. The inside of the two circular holes seven is connected by a bearing to an adjusting cylinder. One end of the adjusting cylinder is fixedly connected with an adjusting gear. A limiting track is fixedly connected to the side of one of the tooling plates. An adjusting tooth rod is slidably connected within the limiting track. A pressing plate is fixedly connected to the side of the adjusting tooth rod. An electric driving rod is fixedly connected to one side of the limiting track.

Two guiding round rods are fixedly connected to the side of the clamping soft plate. Two through holes are opened on one side of the clamping seat. The guiding round rods pass through the through holes. A plurality of universal wheels are fixedly connected at equal distances to the bottom of the tooling rack.

[0016] By setting a clamping module, when gluing the copper clad laminate, first start the screw rod motor, drive the bidirectional screw rod to rotate by the screw rod motor, so that the nut slider moves bidirectionally under the limitation of the limiting round rod, thereby adjusting the distance between the clamping seats on the nut slider. Then place the copper clad laminate inside the clamping seat. Then start the telescopic rod, drive the clamping soft plate to clamp and fix the copper clad laminate by the telescopic rod. Drive the adjusting tooth rod to move within the limiting track by starting the electric driving rod, so that the adjusting tooth rod drives the adjusting gear to drive the adjusting cylinder to rotate, facilitating the reverse side gluing treatment of the copper clad laminate.

[0017] A method for using a glue coating device for a copper clad laminate, using a glue coating device for a copper clad laminate as described above, includes the following steps: Step 1: When the raw materials in the mixing barrel are being stirred and mixed, at this time, by starting the power generation box, the power generation box conducts electricity to the stirring rod at the bottom of the reciprocating slide through a conductive hose, so that the conductive needles on the conductive spheres outside the stirring rod eliminate the bubbles generated during the mixing and stirring process by electric shock; Step 2: At the same time, start the driving motor, and the driving motor drives the rotating support rod on the hollow rotating tube to move in a circle. At this time, the stirring rod moves in a circle. At the same time, the linkage gear at one end of the rotating support rod rotates self - driven under the limitation of the limit circular tooth frame, so that the rotating shaft drives the eccentric shaft on the rotating circular plate to drive the reciprocating slide to move back and forth in the slideway on the rotating support rod, so that the conductive needles on the conductive spheres at the bottom of the reciprocating slide uniformly eliminate the bubbles in the mixing barrel; Step 3: During the rotation of the rotating shaft, the scraper on the compression spring on the rotating long column scrapes the raw materials adhering to the inner wall of the mixing barrel; Step 4: During the process of coating the copper clad laminate, at this time, the excess flowing glue is collected by the collection pool on the tooling rack, and at the same time, start the heating box to heat the electric heating plate through the electric wire, so as to facilitate the collection of the glue in the collection pool into the mixing barrel.

[0018] As can be seen from the above, a glue coating device for a copper clad laminate provided by the present invention has the beneficial effects of eliminating the bubbles generated by the gas brought in during the stirring process of the raw materials, avoiding incomplete removal of the bubbles in the glue, which will cause bubbles after curing, and there will be many pinholes on the surface of the copper clad laminate after drying, seriously affecting the product quality.

[0028] In a specific application scenario, when the raw materials in the mixing barrel 201 are being stirred and mixed, at this time, by starting the power generation box 217, the power generation box 217 conducts electricity to the stirring rod 230 at the bottom of the reciprocating sliding seat 225 through the conductive hose 229, so that the conductive needles 232 on the conductive spheres 231 outside the stirring rod 230 perform electric shock elimination on the bubbles generated during the mixing and stirring process.

Tooling brackets 610 are fixedly connected to the exteriors of the two rotating cylinders 608. A bidirectional gear 609 is fixedly connected to one end of one of the rotating cylinders 608.

[0031] In a specific application scenario, during the process of applying glue to the copper clad laminate, at this time, the hollow roller 4 on the glue application assembly 3 is used to apply glue to the copper clad laminate in multiple directions. Meanwhile, the servo motor 603 is started, and the roller 605 on the rotating push rod 604 driven by the servo motor 603 moves in the slideway of the T-shaped linkage rack 607, so that the toothed block end of the T-shaped linkage rack 607 moves reciprocally, thereby causing the T-shaped linkage rack 607 to drive the bidirectional gear 609 to drive the rotating cylinder 608, making the copper clad laminate on the tooling bracket 610 swing left and right.

The power generation box 217 conducts electricity to the stirring rod 230 at the bottom of the reciprocating slider 225 through the conductive hose 229, so that the conductive needles 232 on the conductive spheres 231 outside the stirring rod 230 perform electric shock elimination on the bubbles generated during the mixing and stirring process; Step 2: At the same time, start the drive motor 215. The drive motor 215 drives the rotary support rod 219 on the hollow rotary tube 216 to move in a circular motion. At this time, the stirring rod 230 moves in a circular motion. At the same time, the linkage gear 223 at one end of the rotary support rod 219 rotates self - clockwise under the limitation of the limiting circular tooth frame 220, so that the rotary shaft 221 drives the eccentric shaft 224 on the rotating circular plate 222 to drive the reciprocating slider 225 to reciprocate in the slideway on the rotary support rod 219, so that the conductive needles 232 on the conductive spheres 231 at the bottom of the reciprocating slider 225 uniformly eliminate the bubbles in the mixing barrel 201; Step 3: During the rotation of the rotary shaft 221, the scraper 204 on the compression spring 234 on the rotary long column 233 scrapes the raw materials adhering to the inner wall of the mixing barrel 201; Step 4: During the process of applying glue to the copper clad laminate, at this time, the excess flowing glue is collected by the collection pool 208 on the tooling rack 1. At the same time, start the heating box 210 to heat the electric heating plate 209 through the electric wire 211, facilitating the collection of the glue in the collection pool 208 into the mixing barrel 201.

[0036] Working principle: When gluing the copper clad laminate, first start the lead screw motor 712. The lead screw motor 712 drives the bidirectional screw 702 to rotate, so that the nut slider 703 moves bidirectionally under the limitation of the limit round rod 701. Then, adjust the distance between the clamping seats 713 on the nut slider 703. After that, place the copper clad laminate inside the clamping seat 713. Then start the telescopic rod 714, and the telescopic rod 714 drives the clamping soft plate 715 to clamp and fix the copper clad laminate. By starting the electric drive rod 710, drive the adjusting tooth rod 708 to move in the limit track 707, so that the adjusting tooth rod 708 drives the adjusting gear 706 to drive the adjusting cylinder 705 to rotate, which is convenient for turning over and gluing the copper clad laminate. During the mixing process of the raw materials in the mixing barrel 201, at this time, start the power generation box 217. The power generation box 217 conducts electricity to the stirring rod 230 at the bottom of the reciprocating slider 225 through the conductive hose 229, so that the conductive needles 232 on the conductive balls 231 outside the stirring rod 230 electrically shock and eliminate the bubbles generated during the mixing process. At the same time, start the drive motor 215. The drive motor 215 drives the rotary support rod 219 on the hollow rotary tube 216 to move in a circular motion. At this time, the stirring rod 230 moves in a circular motion. At the same time, the linkage gear 223 at one end of the rotary support rod 219 rotates self-driven under the limitation of the limit circular tooth frame 220, so that the rotating shaft 221 drives the eccentric shaft 224 on the rotating circular plate 222 to drive the reciprocating slider 225 to reciprocate in the slideway on the rotary support rod 219, so that the conductive needles 232 on the conductive balls 231 at the bottom of the reciprocating slider 225 uniformly eliminate the bubbles in the mixing barrel 201. During the rotation of the rotating shaft 221, the scraper 204 on the compression spring 234 on the rotating long column 233 scrapes the raw materials adhered to the inner wall of the mixing barrel 201. During the gluing process of the copper clad laminate, at this time, the excess flowing glue is collected by the collection pool 208 on the tooling rack 1. At the same time, start the heating box 210 to heat the electric heating plate 209 through the electric wire 211, so as to facilitate the collection of the glue in the collection pool 208 into the mixing barrel 201. Then start the pump body 205. The pump body 205 transports the glue in the mixing barrel 201 to the hollow roller 4 for gluing the copper clad laminate. During the gluing process of the copper clad laminate, at this time, the hollow roller 4 on the gluing assembly 3 performs multi-directional gluing on the copper clad laminate. At the same time, start the servo motor 603. The servo motor 603 drives the roller 605 on the rotary push rod 604 to move in the slideway of the T-shaped linkage tooth rod 607, so that the tooth block end of the T-shaped linkage tooth rod 607 moves reciprocally, so that the T-shaped linkage tooth rod 607 drives the bidirectional gear 609 to drive the rotating cylinder 608 to make the copper clad laminate on the tooling bracket 610 swing left and right, so that when the hollow roller 4 contacts the copper clad laminate for gluing, the glue can be evenly distributed on one side of the copper clad laminate.
