Description

Technical Field

[0001] The invention relates to the field of copper clad plate substrate processing, in particular to PCB copper clad plate substrate processing equipment. Background Art

[0002] The copper clad laminate substrate, also known as the reinforcing material, is the core component in the copper clad laminate production process. It is usually made of wood pulp paper, glass fiber cloth, synthetic fiber cloth, non-woven fabrics and other materials. After these materials are impregnated with resin, they form a substrate with certain strength and insulation properties. The copper clad laminate is a special electronic material with a layer of copper film covered on the surface of the substrate. After the copper clad laminate substrate is impregnated with resin, it is covered with copper foil on one or both sides and then hot pressed.

[0003] When the copper clad laminate is hot-pressed, the surface of the substrate needs to be coated with glue while the copper foil is adhered to its surface. During the coating process, the glue cannot be evenly sprayed onto the substrate due to environmental or equipment vibrations. When the laminating machine presses it, the thickness of the glue coated on the film is different, resulting in poor quality of the pressed copper clad laminate. Therefore, a patent application with patent publication number CN117601448A provides a laminating machine for the production of flexible copper clad laminates, which automatically scrapes off the excessively thick glue coated on the film to keep the thickness of the glue on the film consistent, thereby ensuring the quality of the pressed copper clad laminate. However, under the action of the press pressure, the glue formed by the melted resin will expel the internal air, and the glue will also flow out of the outer edge of the substrate. The resin continues to undergo cross-linking reaction during the hot pressing process and is finally solidified. During this lamination process, the phenomenon of glue flowing out of the outer edge of the substrate is called glue flow. The phenomenon of excessive glue flow causing voids at the edge of the copper clad laminate is called glue deficiency. It will also make the thickness of the edge of the copper clad laminate lower than the middle thickness, reducing the quality of the copper clad laminate. More seriously, the glue flow will flow onto the mirror steel plate, seriously affecting production efficiency and product quality.

[0004] To this end, a PCB copper clad plate substrate processing equipment is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a PCB copper clad board substrate processing equipment to solve the problem that a large amount of glue flows out of the outer edge of the substrate during the hot pressing process of the laminating machine, causing the thickness of the edge of the copper clad board to be lower than the middle thickness or the glue flows onto the mirror steel plate of the laminating machine, resulting in the product quality and production efficiency being affected.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A PCB copper-clad board substrate processing equipment comprises a base, a hydraulic rod is installed on the base, one end of the hydraulic rod is connected to a hot press plate, an annular press plate is arranged on the side wall of the hot press plate, the hot press plate is arranged at the inner side of the annular press plate, a plurality of sliding plates are installed on the annular press plate, the sliding plates are evenly distributed along the inner side of the annular press plate, a sliding part connected to the sliding plate is installed on the hot press plate, a locking part is installed on the top of the hot press plate, the locking part is connected to the sliding plate, when the hydraulic rod pushes the hot press plate to move downward, the annular press plate is driven by the sliding part to first abut against the edge copper foil of the substrate, the hot press plate continues to move downward, the locking part moves away from the sliding plate, so that the hot press plate abuts against the substrate.

[0008] When the pressing equipment is in use, a mechanical arm on one side moves the copper-clad laminate to be hot-pressed to the base through a hydraulic suction cup. At this time, the hydraulic rod pushes the hot pressing plate to move downward continuously to hot-press the copper-clad laminate in the middle. Of course, when the equipment in this scheme is working, while the hydraulic rod pushes the hot pressing plate downward, the hot pressing plate will drive the annular pressing plate installed on its outside to move downward through the sliding part installed on it. Because the annular pressing plate is located directly below the hot pressing plate in the starting position, before the hot pressing plate contacts the copper-clad laminate, the annular pressing plate will first squeeze the edge of the copper-clad laminate, and the copper foil at the edge of the copper-clad laminate will be hot-pressed by squeezing the annular pressing plate. Press so that the upper and lower copper foils can be closed together. Of course, because the sliding part enables the annular pressing plate to slide up and down, it is convenient for the annular pressing plate to press the copper foil. Therefore, in order to improve the firmness between the two copper foils, it is necessary to use a locking part to lock the annular pressing plate. Through the coordinated use of the annular pressing plate and the hot pressing plate, the outer edge of the copper clad laminate is first hot-pressed, and then the copper clad laminate is pressed, so as to avoid the annular pressing plate pressing against the copper foil on its outside when the hot pressing plate is pressed, causing a large amount of glue to flow out of the outer edge of the substrate, resulting in the operator needing to manually or use equipment to clean the outflowing glue to ensure that product quality and production efficiency are not affected.

[0009] Preferably, the sliding member includes a limit frame, a sliding column, and a first compression spring. A plurality of sliding grooves are opened on the hot pressing plate, the sliding plate is arranged in the sliding groove, the limit frame is fixedly installed on the hot pressing plate, the limit frame is arranged above the sliding groove, a sliding column is fixedly installed in the sliding groove, one end of the sliding column is fixedly installed with the limit frame, the sliding plate is slidably connected to the sliding column, the sliding column is sleeved with a first compression spring, and both ends of the first compression spring are respectively abutted against the inner wall of the limit frame and the sliding plate.

[0010] When the annular pressing plate continuously moves downward to press against the copper foil on the base below, the upper and lower copper foils are dissolved together by the hot pressing of the annular pressing plate. When the annular pressing plate is pressed onto the copper foil, the hydraulic rod continues to push the hot pressing plate downward. At the same time, the downward moving hot pressing plate drives the limit frame to move, and the sliding plate is squeezed by the first compression spring in the limit frame, so that the annular pressing plate can press the two copper foils more stably. Of course, when the hot pressing plate is hot pressing the copper clad laminate, the annular pressing plate on the outside needs to be lifted up so as not to interfere with the copper clad laminate being hot pressed in the middle. Therefore, it is necessary to use a slidable structure to allow the annular pressing plate to squeeze the copper foil while lifting the annular pressing plate when the hot pressing plate is hot pressing the copper clad laminate to avoid the annular pressing plate pressing the edge of the copper foil and preventing it from expanding. This ensures that the annular pressing plate hot presses the edge of the copper foil while avoiding the annular pressing plate interfering with the expansion of the edge copper foil.

[0011] Preferably, a groove is provided on the base, a receiving plate is provided in the groove, a lower guide ring is fixedly installed in the groove, an upper guide ring is fixedly installed on the inner side of the annular pressure plate, the lower guide ring and the upper guide plate are both provided with inclined surfaces, and the inclined surface of the upper guide plate faces the outer side of the annular pressure plate, the lower guide ring and the upper guide plate are arranged to cooperate with each other, when the annular pressure plate moves down to the set position, the upper guide ring and the lower guide ring abut against each other and the cross-section is spliced ​​into a rectangular structure, the gap between the inner side wall of the lower guide ring and the receiving plate is 2mm, and the gap between the inner side wall of the upper guide plate and the hot pressing plate is 2mm.

[0012] Because the glue formed by the melted resin will expel the air inside the copper clad laminate, and the glue will also flow out of the outer edge of the substrate. Once the two copper foils are sealed, the air will not be discharged, resulting in quality problems of the extruded copper clad laminate. Therefore, a groove is opened on the base, and a receiving plate is arranged in the groove, so that the copper clad laminate will sink when placed on it, and the lower guide ring is arranged so that when the copper clad laminate is placed on the receiving plate and sinks, the lower guide ring will press against the copper foil below and make it tilt upward, and the annular pressure plate continues to move downward to drive the upper guide ring to move downward. When it moves to the specified position, the upper guide ring is abutted against the lower guide ring to form a rectangular structure, and the upper and lower copper foils are squeezed together, and the gap between the inner wall of the lower guide ring and the receiving plate and the gap between the inner wall of the upper guide plate and the hot pressing plate are set to 2mm, so that the copper foil can be bent through the abutment of the lower guide ring and the upper guide ring. The air generated by the copper clad laminate during hot pressing and a small amount of excess flow glue can enter the space generated during the bending through the copper foil at the abutment, thereby preventing the air generated during pressing from being unable to be discharged, resulting in reduced quality of the copper clad laminate.

[0013] Preferably, a heat insulation film is fixedly installed between the hot pressing plate and the annular pressing plate, and the heat insulation film covers the gap between the hot pressing plate and the annular pressing plate.

[0014] The heat-insulating film arranged between the hot pressing plate and the annular pressing plate can prevent external cold air from entering the hot pressing plate. At the same time, through cooperation with the upper guide plate, the air blown from the outside can be deflected by the inclined surface on the upper guide plate, thereby preventing external air from blowing onto the hot pressing plate, causing the hot pressing plate to require a certain amount of time to preheat when continuing production, thereby ensuring the production efficiency of the product.

[0015] Preferably, a clamping groove is provided on the base, the cross-section of the clamping groove is wavy, and the wave on the side close to the inner groove is a silicone ring, and a clamping sheet is fixedly installed on the annular pressure plate. When the annular pressure plate moves down to a certain position, the clamping sheet and the clamping groove fit together.

[0016] Because the hot pressing plate needs to press the copper clad laminate, and this solution needs to press the copper foil on the side of the copper clad laminate together before pressing to form a closed cavity, and a certain amount of air and glue flow will be generated when the copper clad laminate is pressed. Once the pressed copper foil is not tight enough, the air and glue flow generated by the pressing of the copper clad laminate will burst the cavity formed by the copper foil, so it is necessary to reinforce the position where the two copper foils are pressed. Therefore, the compression groove arranged in a wavy shape and the compression sheet used in conjunction with it are used to make the pressed edge copper foil wavy, and the wavy bonding increases The contact area, at the same time, the wavy joint can also increase the friction between the two copper foils and improve the tightness of the copper foil joint. Of course, because the clamping groove is wavy, when the upper guide ring is extruded, the copper foil on one side that is hot-pressed cannot move due to the pulling caused by the extrusion. Therefore, one of the waves of the clamping groove needs to be changed into silicone material, so that the silicone material will be deformed when the clamping sheet is extruded, to ensure that when the upper guide ring moves down to press the two copper foils, there will be no tearing due to the inability to move the copper foil on one side, thereby ensuring the integrity of the copper foil when it is hot-pressed.

[0017] Preferably, the locking member comprises a push rod, a guide block, a second compression spring, a first ball, an electromagnet, a spherical push block, and a second ball, the top of the hot pressing plate is provided with a plurality of push rods, the top of the hot pressing plate is fixedly installed with a plurality of guide blocks, the push rod is slidably connected to the guide block, the push rod is sleeved with a second compression spring, the hot pressing plate is provided with a placement groove, one end of the second compression spring abuts against the inner wall of the placement groove, one end of the push rod extends into the limit frame and is rotatably connected to the first ball, the first ball abuts against the sliding plate, and the side of the end of the sliding plate away from the hot pressing plate is arc-shaped, the top of the hot pressing plate is provided with a mounting groove, the mounting groove is fixedly installed with an electromagnet, one end of the electromagnet is fixedly installed with a spherical push block, the other end of the push rod extends into the mounting groove and is rotatably connected to the second ball, and the second ball abuts against the spherical push block.

[0018] During use, because the sliding column enables the annular pressure plate to move up and down, when the hot pressing plate pushes the annular pressure plate downward for pressing, the downward pressed annular pressure plate needs to be locked to prevent the upward moved annular pressure plate from failing to press the copper foil below, causing the copper foil to not be able to fit together completely. Specifically, when the hydraulic rod moves to the specified position, the electromagnet is energized, and the energized electromagnet pushes the spherical push block fixed on its iron core to move through the magnetic force generated. Because the spherical push block is a circular structure and abuts against the second ball disposed in the mounting groove, the continuously rising spherical push block will push the surrounding second ball to move outward, and the moving second ball will drive the push block connected thereto. The rod moves, and the moving push rod will squeeze the second compression spring mounted thereon. Because the push rod moves to one side, the first ball at the other end continues to approach the sliding plate, and finally presses against the sliding plate, so that the sliding plate cannot move up and down, allowing the annular pressure plate to stably press the copper foil below. Of course, when the hydraulic rod continues to move downward, the electromagnet is powered off. Because the first ball rolls on the sliding plate, the compressed second compression spring will push the push rod back to its original position, preventing the copper foil from breaking when the hot pressing plate is extruded due to the loose pressure of the annular pressure plate, and preventing the glue from flowing from the edge of the copper clad laminate to the mirror steel plate of the laminating machine, causing problems with product quality and production efficiency.

[0019] Preferably, a piston cylinder is fixedly installed on the base, a third compression spring is installed in the piston cylinder, a lower pressure frame is fixedly installed on the hot pressing plate, when the hot pressing plate descends to a specified position, the lower pressure frame abuts against the piston cylinder, a plurality of first pneumatic telescopic rods are fixedly installed around the groove, a second pneumatic telescopic rod is fixedly installed in the groove, the first pneumatic telescopic rod is connected to the piston cylinder through a first hose, the second pneumatic telescopic rod is connected to the first pneumatic telescopic rod through a second hose, and when the piston cylinder is squeezed, the movable end of the first pneumatic telescopic rod extends earlier than the movable end of the second pneumatic telescopic rod.

[0020] When the hot pressing plate continuously moves downward for extrusion, the hot pressing plate moves to the specified position, so that the lower pressing frame fixed on the hot pressing plate continuously moves downward and presses against the piston cylinder on the base, so that the movable end of the piston cylinder continuously contracts, and the gas in the piston cylinder is introduced into the first pneumatic telescopic rod through the first hose, so that the movable end of the first pneumatic telescopic rod moves upward, and the movable end of the upwardly moved first pneumatic telescopic rod presses back against the annular pressing plate, so that the annular pressing plate moves upward. Because the gas will continuously enter the first pneumatic telescopic rod, after the first pneumatic telescopic rod rises, the gas will enter the second pneumatic telescopic rod through the second hose, so that the movable end of the second pneumatic telescopic rod rises, and the receiving plate rises through the upward movement of the second pneumatic telescopic rod. When the annular pressing plate moves upward to allow the hot pressing plate to move downward to extrude the copper clad laminate, the edge of the copper clad laminate The glue flowing or the discharged gas can open the pressed copper foil, avoiding the copper foil from being broken due to the edge glue flowing or the discharged gas failing to open the copper foil, resulting in a large amount of glue flowing out onto the equipment, avoiding the need for subsequent cleaning and affecting the production efficiency of the product, thereby ensuring product quality and production efficiency.

[0021] Preferably, a plurality of fixing rods are fixedly installed on the side wall of the hot pressing plate, and the fixing rods are arranged in an L shape. A plurality of through holes are opened on the side wall of the upper guide ring. One end of the fixing rod slides in the through hole. When the upper guide ring moves to a specified position, the fixing rod passes through the through hole and is pressed to the other side of the hole.

[0022] When the movable end of the first pneumatic telescopic rod pushes the annular pressing plate upward, the fixed rods in the multiple through holes on the side wall of the guide ring will extend out. The copper foil that may stick to the annular pressing plate will be pushed out by the extension of the fixed rods, thereby preventing the copper foil from sticking to the annular pressing plate and causing the position of the copper clad laminate to change when the hot pressing plate moves down for hot pressing.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The hydraulic rod drives the annular pressing plate to move while pushing the hot pressing plate downward. The annular pressing plate presses the copper foil so that the upper and lower copper foils are squeezed together. Through the coordinated use of the annular pressing plate and the hot pressing plate, the outer edge of the copper clad laminate is first hot-pressed so that the upper and lower copper foils form a closed space, and then the copper clad laminate is pressed to prevent a large amount of glue from flowing out of the outer edge of the substrate and onto the base, thereby ensuring the production quality and efficiency of the product.

[0025] 2. When the annular pressure plate moves downward and drives the upper guide ring to move downward to the specified position, the upper guide ring abuts against the lower guide ring at this time, squeezing the upper and lower copper foils together, so that the copper foil can be bent through the abutment of the lower guide ring and the upper guide ring. Through the two copper foils at the bend and the abutment, the air generated by the copper clad laminate during hot pressing and a small amount of excess flow glue can enter the copper foil at the bend, and a certain space is opened at the two bent copper foils to avoid the air generated during pressing from being unable to be discharged, resulting in bursting at the edge, causing the glue and air to be discharged, thereby indirectly ensuring the production quality and efficiency of the product.

[0026] 3. The movement of the hot pressing plate drives the lower pressing frame on it to move downward and press against the piston cylinder on the base, so that the gas in the piston cylinder is introduced into the first pneumatic telescopic rod and the second pneumatic telescopic rod through the first hose and the second hose, so that the first pneumatic telescopic rod moves up and presses against the annular pressing plate. At the same time, the second pneumatic telescopic rod pushes the receiving plate to rise, and the annular pressing plate moves up to allow the hot pressing plate to move downward to squeeze the copper clad laminate. The glue flowing from the edge of the copper clad laminate or the discharged gas can prop up the pressed copper foil, avoiding a large amount of glue flowing out of the outer edge of the substrate, ensuring that product quality and production efficiency will not be affected.

DETAILED DESCRIPTION

[0036] See also Figures 1 to 8 The present invention provides a PCB copper-clad board substrate processing equipment, and the technical solution is as follows:

[0037] A PCB copper clad board substrate processing equipment includes a base 1, a hydraulic rod 2 is installed on the base 1, one end of the hydraulic rod 2 is connected to a hot pressing plate 3, an annular pressing plate 8 is arranged on the hot pressing plate 3, the hot pressing plate 3 is arranged on the inner side of the annular pressing plate 8, a plurality of sliding plates 18 evenly distributed along the inner side of the annular pressing plate 8 are fixedly installed on the annular pressing plate 8, a sliding part connected to the sliding plate 18 is installed on the hot pressing plate 3, a locking part is installed on the top of the hot pressing plate 3, and the locking part abuts against the sliding plate 18.

[0040] A groove 301 is provided on the base 1, and a receiving plate 4 is installed in the groove 301. A lower guide ring 32 is fixedly installed in the groove 301, and an upper guide ring 26 is fixedly installed on the inner side of the annular pressure plate 8. Both the lower guide ring 32 and the upper guide ring 26 are provided with inclined surfaces, and the inclined surface of the upper guide plate faces the outer side of the annular pressure plate 8. When the annular pressure plate 8 moves down to the set position, the upper guide ring 26 and the lower guide ring 32 abut against each other and the cross-section is spliced ​​into a rectangular structure. The gap between the inner wall of the lower guide ring 32 and the receiving plate 4 is 2 mm, and the gap between the inner wall of the upper guide ring 26 and the hot pressing plate 3 is 2 mm.

[0041] A piston cylinder 14 is fixedly installed on the base 1, and a third compression spring is installed in the piston cylinder 14. A lower pressure frame 13 is fixedly installed on the hot pressing plate 3. When the hot pressing plate 3 descends to a specified position, the lower pressure frame 13 abuts against the piston cylinder 14. A plurality of first pneumatic telescopic rods 6 are fixedly installed around the groove 301. A second pneumatic telescopic rod 30 fixedly installed with the receiving plate 4 is fixedly installed in the groove 301. The first pneumatic telescopic rod 6 is connected to the piston cylinder 14 through a first hose 7, and the second pneumatic telescopic rod 30 is connected to the first pneumatic telescopic rod 6 through a second hose 29.

[0042] A plurality of L-shaped fixing rods 28 are fixedly mounted on the side wall of the hot pressing plate 3, and a plurality of through holes are opened on the side wall of the upper guide ring 26. The fixing rods 28 slide in the through holes. When the upper guide ring 26 moves to a specified position, the fixing rods 28 are pressed and extended to the other side of the hole.

[0043] A pressing groove 5 is provided on the base 1, and the cross section of the pressing groove 5 is wavy, and the wave on one side close to the inner groove 301 is a silicone ring 31, and a pressing sheet 27 that fits with the pressing groove 5 is fixedly installed on the annular pressing plate 8. A heat insulation film 11 is fixedly installed between the hot pressing plate 3 and the annular pressing plate 8, and the heat insulation film 11 covers the gap between the hot pressing plate 3 and the annular pressing plate 8.

[0044] See also Figure 1 , Figure 2 and Figure 3 Before use, it should be noted that the side length of the copper foil in the present invention is greater than the side length of the middle substrate. When in use, the mechanical arm on one side moves the copper clad laminate to be hot-pressed to the base 1 through the hydraulic suction cup. At this time, the hydraulic rod 2 pushes the hot pressing plate 3 to move downward continuously to hot-press the copper clad laminate in the middle. When the annular pressing plate 8 moves downward continuously to press the copper foil on the lower base 1, the upper and lower copper foils are dissolved together by the hot pressing of the annular pressing plate 8. When the annular pressing plate 8 is pressed onto the copper foil, the hydraulic rod 2 continues to push the hot pressing plate 3 to move downward. At the same time, the downward moving hot pressing plate 3 drives the limit frame 9 to move, and the sliding plate 18 is squeezed by the elasticity of the first compression spring 19 in the limit frame 9, so that the sliding plate 18 always presses against the two copper foils.

[0045] See also Figure 3, Figure 4 and Figure 5 When the hydraulic rod 2 moves to the specified position, the electromagnet 24 is energized. The energized electromagnet 24 pushes the spherical push block 25 fixed on its iron core to move through the magnetic force generated. Because the spherical push block 25 is a circular structure and abuts against the second ball 16 set in the mounting groove 23, the continuously rising spherical push block 25 will push the surrounding second ball 16 to move outward, and the moving second ball 16 will drive the push rod 10 connected thereto to move. At the same time, the moving push rod 10 will squeeze the second compression spring 12 sleeved thereon, because the push rod 10 will move to one side, so that the first ball 15 at the other end continues to approach the sliding plate 18, and finally abuts against the sliding plate 18, so that the sliding plate 18 cannot move up and down, so that the annular pressure plate 8 can stably press the copper foil below. Of course, when the hydraulic rod 2 continues to move downward, the electromagnet 24 is de-energized. Because the first ball 15 rolls on the sliding plate 18, the compressed second compression spring 12 will push the push rod 10 back to its original position.

[0046] See also Figure 1 , Figure 2 and Figure 3 At the same time, a groove 301 is opened on the base 1, and a receiving plate 4 is arranged in the groove 301, so that the copper-clad laminate will sink when placed thereon, and the lower guide ring 32 is arranged so that when the copper-clad laminate is placed on the receiving plate 4 and sinks, the lower guide ring 32 will abut against the copper foil below and make it tilt upward. When the annular pressure plate 8 continues to move downward to drive the upper guide ring 26 to move downward to the specified position, the upper guide ring 26 at this time abuts against the lower guide ring 32 to form a rectangular structure, and squeeze the upper and lower copper foils together.

[0047] See also Figure 6 , Figure 7 and Figure 8 By providing a wavy pressing groove 5 on the annular pressing plate 8 and combining it with a pressing sheet 27 that fits therewith, the edge of the pressed copper foil is wavy. The wavy bonding increases the contact area and improves the friction between the copper foils. Of course, because the pressing groove 5 is wavy, the copper foil cannot move when the pressing sheet 27 is pressed, and the upper guide ring 26 will move down at the same time. Therefore, it is necessary to change one of the waves of the pressing groove 5 into a silicone material, so that the silicone material will be deformed when the pressing sheet 27 is pressed, to ensure that when the upper guide ring 26 moves down to press the two copper foils, the copper foil on one side can be slightly stretched.

[0048] See also Figure 6 and Figure 8When the hot pressing plate 3 is continuously moved down for extrusion, the hot pressing plate 3 moves to the specified position, so that the lower pressing frame 13 fixed on the hot pressing plate 3 is continuously moved down and presses against the piston cylinder 14 on the base 1, so that the movable end of the piston cylinder 14 is continuously contracted, and the gas in the piston cylinder 14 is introduced into the first pneumatic telescopic rod 6 through the first hose 7, so that the movable end of the first pneumatic telescopic rod 6 moves up, and the movable end of the first pneumatic telescopic rod 6 that moves up presses back against the annular pressing plate 8, so that the annular pressing plate 8 moves up. Because the gas will continuously enter the first pneumatic telescopic rod 6, after the first pneumatic telescopic rod 6 rises, the gas will enter the second pneumatic telescopic rod 30 through the second hose 29, so that the movable end of the second pneumatic telescopic rod 30 rises, and the second pneumatic telescopic rod 30 moves up, so that the receiving plate 4 rises, and the annular pressing plate 8 moves up to allow the hot pressing plate 3 to move down to extrude the copper clad laminate, and the glue flowing or discharged from the edge of the copper clad laminate can open the pressed copper foil.
