Description

Technical Field

[0001] This invention relates to the field of circuit board manufacturing technology, and more specifically to a copper clad laminate processing film laminating machine for circuit board manufacturing. Background Technology

[0002] Generally speaking, copper clad laminate is the core substrate for PCB production. Before the etching, exposure, and electroplating processes of the circuit board, a photosensitive film needs to be applied to the surface of the copper clad laminate to achieve precise pattern transfer and etching processes, thereby forming the required circuit pattern on the copper clad laminate. Its bonding accuracy and bonding quality directly determine the yield of the finished circuit board.

[0003] The prior art discloses a copper-clad laminate (CCL) processing film application machine for circuit board production (publication number CN119383842B). A lead screw motor drives an electric suction cup downwards, which in turn moves a photosensitive film downwards, bringing it into contact with the CCL and applying it to the CCL. A pressure plate holds the photosensitive film in place, preventing misalignment during subsequent processing. This automatic film application and fixation reduces manual operation and improves production efficiency. A pusher moves a contact frame downwards, which in turn moves a pressure plate downwards, flattening the CCL in the conveyor trough. This flat surface reduces air residue between the photosensitive film and the CCL, preventing bubble formation. A sliding plate moves a moving plate downwards, which in turn moves a straightening plate downwards, correcting the position of the CCL and ensuring tight contact between the photosensitive film and the CCL.

[0004] However, the device still has the following problems: During the manufacturing, transportation, handling and storage of the photosensitive film, its adhesive surface is easily contaminated with dust, fibers, oil or other tiny particulate impurities in the air. The film-applying mechanism of the existing device (such as electric suction cups and pressure plates) is only responsible for mechanical positioning and bonding, and does not have any cleaning function for the photosensitive film adhesive surface. When the photosensitive film with impurities is directly pressed onto the surface of the copper-clad laminate, the particles will be embedded between the copper foil layer of the copper-clad laminate or the adhesive layer of the photosensitive film under pressure. This not only causes local loose bonding, air bubbles or wrinkles, but more seriously, in the subsequent flattening, straightening or rolling processes, hard particles will scratch the surface of the copper-clad laminate with relative movement, forming scratches, pits or oxidation points, which directly affect the conductivity and pattern accuracy of the circuit board and reduce the product yield. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a copper-clad laminate (CCL) lamination machine for circuit board production. This machine achieves the following: before laminating the photosensitive film to the CCL, the adhesive roller assembly, driven by a rotating motor and a gear mechanism, reciprocates horizontally, effectively removing dust, oil, and microparticles from both material surfaces with the flexible pressure provided by a return spring. Subsequently, the dual-pressing assembly applies pressure synchronously in opposite directions through geared upper and lower rollers, ensuring a tight bond between the film and the board. Cleaning and pressing are integrated into a single, sequential process, avoiding secondary contamination, significantly reducing defects such as bubbles and wrinkles, and improving product yield.

Return springs are symmetrically arranged on the U-shaped carriage, and a bracket is mounted on the return spring. The sticking roller is mounted on the bracket.

[0007] As a further aspect of the present invention: the conveying assembly further includes long plates, which are symmetrically arranged on the base and located on both sides of each conveyor belt. A copper-clad plate is provided on the conveyor belt on one side of the double-pressing assembly, and a photosensitive film is provided on the conveyor belt on the side away from the double-pressing assembly. The photosensitive film is adsorbed by a pneumatic suction cup, and a correction assembly is provided on the long plates on both sides of the conveyor belt on the side of the photosensitive film.

[0008] As a further aspect of the present invention: the correction assembly includes an arc-shaped plate, and sliders are provided on both sides of the arc-shaped plate via arc-shaped rods. The sliders are slidably connected to a fixed rod, which is set on a long plate. A compression spring is provided at one end of the slider and on one side of the long plate, and the compression spring is sleeved on the fixed rod.

[0009] As a further aspect of the present invention: a servo motor is provided on the base, the servo motor provides power to the two conveyor belts, and a pulley is provided on the drive shaft of the servo motor and at one end of the lower pressure roller, the servo motor and the lower pressure roller are connected by the pulley belt.

[0010] As a further aspect of the present invention: an electric push rod is provided on the base, the electric push rod is located on one side of the two long plates of the conveyor belt on the side where the copper-clad laminate is placed, and arc-shaped clamps are provided on the two long plates of the conveyor belt on the side where the copper-clad laminate is placed. The arc-shaped clamps on the side closer to the electric push rod are connected to the electric push rod through a connecting push block, and the arc-shaped clamps on the side farther from the electric push rod are connected to the long plates through a connecting rod. A correction spring is provided between the arc-shaped clamps on the side farther from the electric push rod and the long plates on the same side, and the correction spring is sleeved on the connecting rod.

[0011] As a further aspect of the present invention: the transplanting assembly further includes a second servo motor, and the second servo motor is connected to a lead screw, and the second servo motor is fixedly mounted on the gantry frame.

[0012] As a further aspect of the present invention: the telescopic component further includes a limiting slide post, which is symmetrically arranged on both sides of the cylinder, and the limiting slide post passes through the movable seat and connects to the rectangular seat.

[0013] As a further aspect of the present invention: the adhesive roller assembly further includes a connecting slide rod, one end of which is fixedly connected to the bracket, the other end of which is slidably connected to the U-shaped slide, and the correction spring is sleeved on the connecting slide rod.

[0014] The beneficial effects of this invention are: (1) In this invention, through the coordinated control of the conveying component, the transfer component (lead screw + limit slide bar + cylinder + pneumatic suction cup) and the double pressing component, the automatic adsorption, translation positioning and precise release of the photosensitive film and the automatic conveying and pressing of the copper-clad board are realized. No manual intervention is required throughout the process, forming a streamlined operation from feeding to finished product, which greatly shortens the single-piece processing cycle and meets the needs of mass production of circuit boards.

[0015] (2) In this invention, before the photosensitive film and the copper-clad laminate are bonded, the adhesive roller assembly rolls back and forth in the horizontal direction with the help of the gear tooth mechanism driven by the rotating motor, and with the flexible pressure provided by the reset spring, effectively removes dust, oil and micro particles from the surfaces of the two materials; then the double pressing assembly applies pressure synchronously in opposite directions through the upper and lower pressure rollers with gear meshing, so that the film and the board are tightly bonded. Cleaning and pressing are completed in the same station in sequence, avoiding secondary pollution, significantly reducing defects such as bubbles and wrinkles, and improving product yield.

[0016] (3) In this invention, the adhesive roller assembly is connected to the bracket by a reset spring, so that the adhesive roller always sticks to the material surface during the rolling process but the pressure is controllable. This ensures the cleaning effect and prevents the photosensitive film or copper-clad laminate from being scratched or deformed due to hard squeezing. At the same time, the double pressing assembly realizes the synchronous reverse rotation of the upper and lower pressure rollers through gear transmission, and the pressure distribution is uniform, further avoiding damage to the substrate caused by local overpressure. It is suitable for copper-clad laminates and photosensitive films of different thicknesses, and enhances the versatility and reliability of the equipment. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 As shown, the present invention is a copper clad laminate processing film laminating machine for circuit board production, including a conveying assembly 1, on which a transfer assembly 2 is provided; The conveying assembly 1 includes a base 105, on which conveyor belts 107 are symmetrically arranged, and a double pressing assembly 109 is arranged on one side of one of the conveyor belts 107. The double pressing assembly 109 includes an upper pressing roller 1092 and a lower pressing roller 1091. One end of the upper pressing roller 1092 and the lower pressing roller 1091 is respectively provided with a gear 1094 and a gear 2 1093, and the gear 1094 and the gear 2 1093 are meshed together. The transplanting assembly 2 includes a gantry frame 202, which is symmetrically arranged on the base 105. A limiting slide rod 204 and a lead screw 203 are provided between the two gantry frames 202. A telescopic assembly 205 is provided on the lead screw 203 and the limiting slide rod 204. An adhesive roller assembly 208 is provided on the telescopic assembly 205. The telescopic assembly 205 includes a movable seat 2053, one end of which is threadedly connected to a lead screw 203, and the other end of which is slidably connected to a limiting slide rod 204. A cylinder 2051 is provided on the movable seat 2053, and a rectangular seat 206 is provided on the telescopic end of the cylinder 2051. A pneumatic suction cup 207 is provided on the lower surface of the rectangular seat 206, and a rotating motor 209 is provided on the upper surface of one side of the rectangular seat 206. A gear 210 is provided on the rotating motor 209. The sticking roller assembly 208 includes a U-shaped carriage 2081, which is mounted on a rectangular seat 206. Limiting plates 2084 are symmetrically arranged on the U-shaped carriage 2081. One of the limiting plates 2084 is provided with teeth, which mesh with gear 210. Return springs 2082 are symmetrically arranged on the U-shaped carriage 2081. A bracket 2086 is provided on the return spring 2082, and a sticking roller 2083 is provided on the bracket 2086.

[0022] The implementation principle of this invention is as follows: After the equipment is started, the operator places the copper-clad laminate and photosensitive film to be processed onto the two symmetrical conveyor belts 107 of the conveying assembly 1, respectively. The conveying assembly 1 is supported by the base 105, and the two conveyor belts 107 run synchronously, sequentially feeding the copper-clad laminate and photosensitive film into the designated workstation. At this time, the transfer assembly 2 begins to work: the gantry 202 spans across the base 105, and the two gantry 202 are installed in parallel between the limiting slide rods 204 and the lead screw 203; one end of the moving seat 2053 is threaded into the lead screw 203, and the other end is sleeved on the limiting slide rod 204. The rotation of the lead screw 203 drives the moving seat 2053 to move precisely in the horizontal direction to the position of the photosensitive film. Upon reaching the target position, the cylinder 2051 in the telescopic assembly 205 extends downward, pushing the rectangular base 206 down. This causes the pneumatic suction cup 207 on the lower surface of the rectangular base 206 to contact the photosensitive film and generate negative pressure, thus firmly adsorbing the photosensitive film. The cylinder 2051 then retracts, raising the photosensitive film to a safe height. Next, the lead screw 203 continues to rotate, moving the movable base 2053 along with the adsorbed photosensitive film to directly above the copper-clad laminate. At this point, the cylinder 2051 extends again, causing the photosensitive film to descend smoothly above the copper-clad laminate, leaving space for the adhesive roller 2083 to roll. Just before the photosensitive film contacts the copper-clad laminate, the adhesive roller assembly 208 intervenes in the cleaning process. A rotating motor 209 is installed on the rectangular base 206. A gear 210 is fixed to the end of the shaft; a U-shaped carriage 2081 is slidably mounted on a rectangular base 206, and a limiting plate 2084 on one side of the carriage has teeth that mesh with the gear 210. When the rotating motor 209 starts, the gear 210 drives the U-shaped carriage 2081 to move horizontally along the rectangular base 206 through the teeth. At the same time, the bracket 2086 connected to the U-shaped carriage 2081 by a return spring 2082 moves accordingly. The adhesive roller 2083 on the bracket 2086 rolls between the photosensitive film and the copper-clad laminate, using adhesion to remove dust, oil, and small particles from the surfaces of both, ensuring the cleanliness of the bonding interface. The return spring 2082 provides flexible pressure, so that the adhesive roller 2083 always adheres tightly to the material surface without... After the damaged film is cleaned, the dual-pressing assembly 109 begins the final pressing. The dual-pressing assembly 109 is located on one side of one of the conveyor belts 107 and consists of an upper pressure roller 1092 and a lower pressure roller 1091. The ends of the two pressure rollers are respectively equipped with meshing gear 1094 and gear 2 1093. When the copper-clad laminate and the photosensitive film enter the gap between the pressure rollers along with the conveyor belt 107, the gear transmission causes the upper and lower pressure rollers to rotate synchronously in opposite directions, applying uniform pressure to the stacked materials and tightly adhering the photosensitive film to the surface of the copper-clad laminate, completing the pressing and adhering process. Throughout the process, the components work together to achieve fully automatic continuous operation from feeding, adsorption and transfer, cleaning to pressing, effectively improving the production efficiency and product quality of the circuit board.

[0023] like Figures 1-3As shown, in a preferred embodiment of the present invention, the conveying assembly 1 further includes long plates 106, which are symmetrically arranged on the base 105 and located on both sides of each conveyor belt 107. A copper-clad laminate is disposed on the conveyor belt 107 on one side of the double-pressing assembly 109, and a photosensitive film is disposed on the conveyor belt 107 on the side away from the double-pressing assembly 109. The photosensitive film is adsorbed by a pneumatic suction cup 207. Correction assemblies 110 are disposed on the two long plates 106 on the two sides of the conveyor belt 107 on the side of the photosensitive film. The correction assembly 110 includes an arc-shaped plate 1104, and sliders 1103 are disposed on both sides of the arc-shaped plate 1104 via arc-shaped rods. The slider 1103 is slidably connected to the fixed rod 1102, which is set on the long plate 106. One end of the slider 1103 and one side of the long plate 106 are provided with a compression spring 1101, which is sleeved on the fixed rod 1102. It should be noted that, firstly, the correction component 110, through the synergistic effect of the arc plate 1104, the arc rod, the slider 1103 and the compression spring 1101, can automatically adjust the lateral offset of the photosensitive film on the conveyor belt 107 in real time, ensuring that the photosensitive film is always in a precise centered position, thereby greatly improving the success rate and stability of the pneumatic suction cup 207 adsorption, and avoiding bonding deviation or scrap due to film skew.

[0024] like Figures 1-2 As shown in the preferred embodiment of the present invention, a servo motor 108 is provided on the base 105. The servo motor 108 provides power to the two conveyor belts 107. A pulley is provided on the drive shaft of the servo motor 108 and at one end of the lower pressure roller 1091. The servo motor 108 and the lower pressure roller 1091 are connected by a belt through the pulley. It should be noted that the belt connection between the servo motor 108 and the lower pressure roller 1091 through the pulley can effectively absorb the instantaneous impact during start-up, shutdown and load changes, avoid the vibration and creep phenomenon that may be generated by rigid transmission, and ensure that the two conveyor belts 107 and the lower pressure roller 1091 are always in a synchronous and stable operating state.

[0025] like Figures 1-2As shown, in a preferred embodiment of the present invention, an electric push rod 101 is provided on the base 105. The electric push rod 101 is located on one side of the two long plates 106 of the conveyor belt 107 on the side where the copper-clad laminate is placed. Arc-shaped clamping pieces 104 are provided on the two long plates 106 of the conveyor belt 107 on the side where the copper-clad laminate is placed. The arc-shaped clamping piece 104 on the side closer to the electric push rod 101 is connected to the electric push rod 101 through a connecting push block 102. The arc-shaped clamping piece 104 on the side away from the electric push rod 101 is connected to the long plate 106 through a connecting rod. A correction spring 103 is provided between the arc-shaped clamping piece 104 on the side away from the electric push rod 101 and the long plate 106 on the same side. The bias spring 103 is sleeved on the connecting rod. It should be noted that, firstly, the electric push rod 101 drives the connecting push block 102, which moves the arc-shaped clamping piece 104 on one side to the arc-shaped clamping piece 104 on the other side. This can quickly and stably clamp the copper-clad board in the center of the conveyor belt 107, avoiding the board from deviating due to conveyor vibration or external interference, and greatly improving the positioning accuracy. Secondly, a correction spring 103 is provided on the arc-shaped clamping piece 104 on the side away from the electric push rod 101. When a small angular deviation occurs when the edge of the board contacts the clamping piece during the clamping process, the spring can automatically absorb the impact and apply an elastic restoring force, so that the copper-clad board always fits the predetermined trajectory, effectively eliminating edge damage or warping deformation caused by hard extrusion.

[0026] like Figure 4 As shown in the preferred embodiment of the present invention, the transplanting assembly 2 further includes a second servo motor 201, which is connected to a lead screw 203. The second servo motor 201 is fixedly mounted on the gantry frame 202. It should be noted that by directly connecting the second servo motor 201 to the lead screw 203 and fixing it to the gantry frame 202, high-precision closed-loop control and power transmission are achieved. The servo motor has the characteristics of fast response and accurate positioning. Combined with the rolling friction transmission of the lead screw 203, it can effectively eliminate the elastic slippage and gap error in traditional belt or chain transmission, ensuring the linearity of the motion trajectory and the repeatability of the positioning accuracy during transplanting.

[0027] like Figures 4-5 As shown in the preferred embodiment of the present invention, the telescopic component 205 further includes a limiting slide post 2052. The limiting slide post 2052 is symmetrically arranged on both sides of the cylinder 2051, and the limiting slide post 2052 passes through the moving seat 2053 and connects to the rectangular seat 206. It should be noted that by symmetrically arranging the limiting slide post 2052 and connecting it through the moving seat 2053 and the rectangular seat 206, the rectangular seat 206 can be effectively guided to slide precisely in the vertical direction, significantly suppressing the tilting and swaying caused by uneven thrust of the cylinder 2051 or load eccentricity, thereby ensuring that the rectangular seat 206 always maintains a horizontal posture and moves down smoothly throughout the entire stroke.

[0028] like Figures 6-7 As shown, in a preferred embodiment of the present invention, the sticking roller assembly 208 further includes a connecting slide rod 2085. One end of the connecting slide rod 2085 is fixedly connected to the bracket 2086, and the other end of the connecting slide rod 2085 is slidably connected to the U-shaped slide 2081. The correction spring 103 is sleeved on the connecting slide rod 2085. It should be noted that the correction spring 103 sleeved on the connecting slide rod 2085 not only obtains stable axial constraint, but also ensures that the compression and rebound of the spring always follow a predetermined trajectory, thereby ensuring that the correction force acts uniformly and continuously on the sticking roller 2083, which greatly improves the correction accuracy and repeatability reliability.
