A laminating equipment for manufacturing copper clad laminates

Abstract

This invention relates to the field of copper clad laminate manufacturing technology, specifically to a lamination equipment for copper clad laminate manufacturing, comprising a conveying unit and a stacking unit. The invention uses a support conveyor to clamp and convey copper foil and prepreg, ensuring that the surfaces of the copper foil and prepreg are fully stressed, preventing bending due to gravity in the middle during conveying. Through the cooperation of a stop frame and a cooperating stop frame, the front and rear ends of the prepreg, substrate, and copper foil are squeezed and limited, aligning the front and rear ends of the prepreg, substrate, and copper foil. Simultaneously, an adjusting frame drives the left-side support conveyor to clamp and limit the left and right ends of the prepreg, substrate, and copper foil, aligning them. Then, the stacked and aligned prepreg, substrate, and copper foil are forward-feeded out of the equipment and enter the laminator for lamination, improving the lamination efficiency of the copper clad laminate.

Description

Technical Field

[0001] This invention relates to the field of copper clad laminate manufacturing technology, specifically to a lamination device for manufacturing copper clad laminates. Background Technology

[0002] Copper clad laminate is a raw material in the electronics industry. The structure of copper clad laminate includes copper foil, prepreg and substrate. It is a product made by using wood pulp paper or fiberglass cloth as reinforcing materials, impregnating it with resin, covering one or both sides with copper foil, and then hot pressing it.

[0003] In actual manufacturing processes, for large-sized copper-clad laminates, the existing transportation method generally involves clamping and transporting the copper foil, prepreg, and substrate from both sides, then stacking them. The stacked copper foil, prepreg, and substrate are then transported together to a laminator for alignment, and finally vacuum heating and lamination are performed to form the copper-clad laminate. Due to gravity, the copper foil, prepreg, and substrate may sag and deform in the middle during transportation, resulting in them not being able to fully adhere after stacking. Furthermore, the copper foil, prepreg, and substrate may experience significant positional misalignment during stacking, thus requiring an additional flattening process. After flattening for a period of time to ensure that the copper foil, prepreg, and substrate remain flat, they are then aligned, which takes a considerable amount of time and results in low lamination efficiency.

[0028] See Figure 3 The first conveyor frame 12 includes a fixed bracket 121. The fixed bracket 121 is symmetrically fixedly installed on the upper end of the fixed base plate 11. The fixed bracket 121 is symmetrically rotatably connected to the front and rear of the sprocket 122. The front and rear opposite sprocket 122 are connected by a toothed chain belt 123.

The horizontal section of the right angle bracket 124 facing the toothed chain belt 123 is fixedly installed with an arc-shaped support plate 125. The arc-shaped support plate 125 and the toothed chain belt 123 are slidably connected. The structure of the second conveyor frame 13 is the same as that of the first conveyor frame 12, except that the part dimensions are not exactly the same.

[0029] See Figure 2 The adjustment frame 21 includes an L-shaped bracket 211. The upper rear side of the conveyor frame 12 is fixedly equipped with an L-shaped bracket 211. The front end of the horizontal section of the L-shaped bracket 211 is fixedly equipped with an electric slide rail 212. The electric slider on the electric slide rail 212 slides left and right. The lower end of the electric slider is symmetrically equipped with a distance control cylinder 213. The lower end of the distance control cylinder 213 is provided with a support conveyor frame 22 to support the lower end of the substrate, the prepreg and the copper foil.

[0030] See Figure 2 and Figure 3The supporting transport frame 22 includes an inverted U-shaped bracket 221. The lower end of the distance control cylinder 213 is fixedly installed with the inverted U-shaped bracket 221. The lower end of the vertical section of the inverted U-shaped bracket 221 is fixedly installed with a horizontal plate 222. The horizontal plate 222 is symmetrically fixedly installed with electric slide rails 223. The electric sliders 224 on the electric slide rails 223 slide back and forth. The lower end of the horizontal section of the inverted U-shaped bracket 221 is fixedly installed with a distance adjustment cylinder 225. The two electric sliders 224 on the same side are hinged to each other with symmetrically arranged linkage rods 226. The ends of the linkage rods 226 on the same side away from the electric sliders 224 are hinged to a linkage block 227. The telescopic end of the distance adjustment cylinder 225 is fixedly connected to the upper end of the linkage block 227. The lower end of the electric sliders 224 is symmetrically fixedly installed with L-shaped clamping support plates 228.

[0031] See Figure 3 The clamping and mating frame 23 includes a clamping and mating plate 231. The clamping and mating plates 231 are slidably connected to the vertical ends of the opposite vertical sections of the left and right clamping support plates 228. The linkage block 227 is symmetrically arranged with telescopic groups. The telescopic groups are composed of telescopic plates 232 that are symmetrically arranged front and back. A connecting plate 233 is fixedly connected between the lower end of the telescopic plate 232 and the corresponding clamping and mating plate 231. The telescopic plate 232 and the clamping support plate 228 are slidably connected up and down.

[0032] See Figure 3 On the left side, the clamping plates 231 of the clamping frame 23 are all fixedly installed with compression springs 234, and the lower ends of the compression springs 234 are all fixedly installed with contact plates 235. The adsorption plate 241 is fixedly connected to the four contact plates 235.

[0033] See Figure 4 The adsorption rack 24 includes an adsorption plate 241. The adsorption plate 241 is fixedly installed between the four clamping plates 231 on the right side and between the four contact plates 235 on the left side. Rubber suction cups 242 are evenly fixedly installed at the lower end of the adsorption plate 241. Adjacent rubber suction cups 242 are connected to each other. An air pump 243 is fixedly installed in the middle of the upper end of the adsorption plate 241. A connecting pipe 244 is fixedly connected between the air pump 243 and the adjacent rubber suction cups 242.

[0034] Driven by an external motor, sprocket 122 rotates. The prepreg, substrate, and copper foil are placed from right to left on the right toothed chain belt 123, the conveyor belt, and the left toothed chain belt 123, respectively. When the prepreg, substrate, and copper foil are conveyed to the electric slide rail 212, the inverted U-shaped bracket 221 is moved down by the distance control cylinder 213, and the linkage block 227 is moved down by the distance adjustment cylinder 225, thereby causing the clamping support plate 228 to move towards each other to clamp the prepreg. At the same time, the linkage block 227 moves the telescopic plate 232 down, and the clamping mating plate 231 moves down. The adsorption rack 24 moves down synchronously to contact the upper surface of the prepreg. The air pump 243 discharges gas from the rubber suction cup 242 and the prepreg, thereby adsorbing the prepreg and moving it away from the right conveyor rack 12.

[0035] The adjusting frame 21 continues to drive the right support conveyor frame 22 to move to the left, thereby transporting the prepreg to above the second conveyor frame 13. The left support conveyor frame 22 moves to the left toothed chain belt 123. The left support conveyor frame 22 moves down to clamp the copper foil. The adsorption frame 24 adsorbs the upper surface of the copper foil. The right support conveyor frame 22 places the prepreg on the substrate. At this time, the adjusting frame 21 drives the left support conveyor frame 22 to move to the right, thereby transporting the copper foil to above the prepreg on the second conveyor frame 13.

[0036] See Figure 3 and Figure 4 The extrusion support frame 14 includes mounting blocks 141. Mounting blocks 141 are uniformly fixedly mounted on the surface of the toothed chain belt 123 of the second conveyor frame 13. Two adjacent mounting blocks 141 are connected by pins to form a conveyor belt. Limiting grooves 142 are uniformly opened at the end of the conveyor belt away from the toothed chain belt 123. Cylindrical springs 143 are uniformly fixedly mounted in the limiting grooves 142. The end of the cylindrical springs 143 in each limiting groove 142 away from the toothed chain belt 123 of the second conveyor frame 13 is fixedly mounted with a support block 144. The support block 144 is slidably connected to the conveyor belt.

[0037] See Figure 3 and Figure 5 The mating support frame 15 includes mating blocks 151. The fixed support 121 of the second conveyor frame 13 is rotatably connected to both the left and right sides of the upper front side of the fixed support 121. The upper end of the right mating block 151 is provided with a rectangular groove. Fixed springs 152 are uniformly fixedly installed at the bottom of the rectangular groove. The upper ends of the fixed springs 152 are all fixedly installed with a heightening block 153. The upper end of the left mating block 151 is fixedly installed with a heightening block 153. The distance between the mating blocks 151 on the left and right sides is greater than the length of the abutment block 144.

[0038] See Figure 3 and Figure 5The control frame 16 includes a bevel gear 161. The lower end of the mating block 151 is fixedly installed with bevel gear 161. The front side of the fixed bracket 121 of the conveyor frame 13 is symmetrically connected to bevel gear 162. The bevel gear 162 meshes with the corresponding bevel gear 161. The front end of the bevel gear 162 is fixedly installed with a rotating cylinder 163. The rotating cylinder 163 is fixedly installed with a sprocket 164. The left and right opposite sprockets 164 are connected by a toothed chain belt 165. The front end of the rotating cylinder 163 on the right side is fixedly installed with a handle 166.

[0039] The right-side support conveyor 22 continues to move downwards to clamp the next prepreg. The left-side support conveyor 22 places the copper foil on the prepreg. At this time, the conveyor 13 moves, causing the abutment frame to move forward. With the cooperation of the abutment frame 15, the front and rear ends of the prepreg, substrate, and copper foil are squeezed and limited, aligning the front and rear ends of the prepreg, substrate, and copper foil. Simultaneously, the adjusting frame 21 drives the left-side support conveyor 22 to clamp and limit the left and right ends of the prepreg, substrate, and copper foil, aligning them. This is achieved through external mechanisms. The coating machine coats the four ends of the substrate with adhesive. Then, by turning the handle 166, the rotating cylinder 163 is driven to rotate. Under the adjustment of the toothed chain belt 165 and the sprocket 164, the mating block 151 is driven to rotate, no longer obstructing the front end of the prepreg, substrate and copper foil after alignment. Under the conveyor of the conveyor frame 13, the superimposed and aligned prepreg, substrate and copper foil are sent forward out of the equipment. Through the external belt conveyor, they enter the laminator for lamination. The conveyor frame 13 continues to drive the next substrate forward, repeating the previous operation.

[0040] Working principle of the invention: Step 1: First, the prepreg, substrate and copper foil are placed on the right conveyor frame 12, the support frame and the left conveyor frame 12 respectively in the order from right to left. When the prepreg, substrate and copper foil are conveyed to the bottom of the stacking unit 2, the right support conveyor frame 22 is moved down by the adjustment frame 21 to clamp the prepreg. The adsorption frame 24 adsorbs the upper surface of the prepreg and moves it away from the right conveyor frame 12.

[0041] Step 2: The adjusting frame 21 continues to move the right support conveyor frame 22 to the left, thereby transporting the prepreg to above the second conveyor frame 13. The left support conveyor frame 22 moves to the left conveyor frame 12. The left support conveyor frame 22 moves down to clamp the copper foil. The adsorption frame 24 adsorbs the upper surface of the copper foil. The right support conveyor frame 22 places the prepreg on the substrate. At this time, the adjusting frame 21 moves the left support conveyor frame 22 to the right, thereby transporting the copper foil to above the prepreg on the second conveyor frame 13.

[0042] Step 3: The right-side support conveyor 22 continues to move downwards to clamp the next prepreg. The left-side support conveyor 22 places the copper foil on the prepreg. At this time, the second conveyor 13 moves, causing the abutment frame to move forward. With the cooperation of the abutment frame 15, the front and rear ends of the prepreg, substrate, and copper foil are squeezed and limited, aligning the front and rear ends of the prepreg, substrate, and copper foil. At the same time, the adjusting frame 21 drives the left-side support conveyor 22 to clamp and limit the left and right ends of the prepreg, substrate, and copper foil, aligning them. The four ends are then coated by an externally installed coating machine. Then, the control frame 16 adjusts the abutment frame 15 to prevent it from continuing to obstruct the front end of the stacked and aligned prepreg, substrate, and copper foil. Under the conveying of the second conveyor 13, the stacked and aligned prepreg, substrate, and copper foil are sent forward out of the equipment and into the laminator for lamination. The second conveyor 13 continues to move the next substrate forward, repeating the previous operation.
