Description

Technical Field

[0001] This application relates to the field of copper plate surface treatment technology, and in particular to a multi-layer combined copper plate surface treatment process. Background Technology

[0002] Multilayer composite copper clad laminate, also known as copper-clad laminate, is a sheet material made by impregnating reinforcing materials with resin, covering one or both sides with copper foil, and then hot-pressing them. Copper-clad laminate is a basic material in the electronics industry, mainly used in the processing and manufacturing of printed circuit boards, and is widely used in electronic products such as televisions, radios, computers, and mobile communications.

[0003] During the production process of copper clad laminates in the workshop, dust can easily accumulate on the surface of the laminates due to factors such as static electricity and air quality. In order to ensure product quality, it is necessary to clean them thoroughly.

[0004] Chinese Patent CN211488709U discloses a dust removal device for the surface of a copper-plated sheet, including a frame and a conveyor belt. A top plate is fixed to the upper wall of the frame via columns, and a fan hood is fixed to the top of the top plate. The fan hood and a collection box fixed to the upper wall of the top plate are connected via a duct. A suction pump is installed on the duct. Multiple arc-shaped grooves are formed on the lower wall of the fan hood, and brush rollers are installed inside the arc-shaped grooves. Multiple through holes are formed on the groove walls, and multiple protrusions are fixed on the groove walls. The frame and conveyor belt allow for automatic feeding of the copper-plated sheet. The brush rollers clean the dust on the copper-plated sheet. During the rotation of the brush rollers, the brushes on the rollers contact the protrusions, causing the dust on the brushes to fall off, thus cleaning the brush rollers. The connecting pipe and suction pump transport the dust to the collection box, minimizing the amount of dust entering the air.

[0005] However, existing copper plate surface dust removal devices can only clean dust on one side of the copper plate. After cleaning one side of the copper plate, the copper plate needs to be manually collected, flipped, and reloaded before the dust on the other side can be cleaned. This not only reduces cleaning efficiency but also increases the workload of workers. Therefore, further improvements are needed. Summary of the Invention

The cleaning roller cleans the front of the copper plate, achieving front dust removal of the copper plate; in S30, the conveyor belt drives the mounting block to rotate... The copper plate is rotated to face down. Then, the clamping blocks of the clamping assembly, under the action of the feeding plate, overcome the elastic force of the elastic element and open, allowing the copper plate to fall freely from the slot onto the inclined feeding plate. Finally, it slides down and collects in the transfer drum, achieving the flipping and collection of the copper plate. In S40, the conveyor belt of the bottom dust removal mechanism drives the mounting block to rotate and passes under the transfer drum, repeating steps similar to S10, achieving a secondary gripping of the copper plate. In S50, the conveyor belt drives the mounting block to rotate and passes under the cleaning roller, repeating steps similar to S20, achieving back-side dust removal of the copper plate. In S60, the conveyor belt drives the mounting block to rotate until the copper plate is placed back-side down, repeating steps similar to S30, achieving the unloading and collection of the copper plate. Ultimately, the dust removal device achieves the initial gripping, front-side dust removal, flipping and collection, secondary gripping, back-side dust removal, and unloading and collection of the copper plate. Furthermore, the dust removal device can automatically flip and load the copper plate, improving the automation level of the production line, increasing cleaning efficiency, and reducing the workload of workers.

[0023] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0024] This application discloses a multi-layer composite copper plate surface treatment process.

[0025] Reference Figure 1 The multi-layer composite copper plate surface treatment process includes the following steps: S1. Feeding: Multiple stacked copper plates are manually placed into the cylindrical feeding cylinder 1. The copper plates are also stacked in the feeding cylinder 1. S2, Double-sided dust removal: The copper plate is sequentially grabbed, dusted from the front, flipped and collected, grabbed again, dusted from the back, and collected after being unloaded. The multiple copper plates after unloading are also stacked. S3. Dustproof encapsulation: The dustproof film is manually wrapped and fixed on the outside of the copper plates that are collected by the dust removal device and are stacked together, in order to prevent the copper plates from being contaminated secondary. The copper plate is first gripped, the front side is dusted, flipped and collected, then gripped again, the back side is dusted, and the plate is unloaded and collected. This improves the automation of double-sided cleaning of copper plates, eliminating the need for manual collection, flipping, and reloading, thus increasing cleaning efficiency and reducing the workload of workers.

[0026] Reference Figure 1-3 The dust removal device specifically includes a frame 2, two dust removal mechanisms 3, a transfer cylinder 4, and a discharge cylinder 5; wherein, the bottom of the upper discharge cylinder 1 is fixed to the top of the frame 2, the two dust removal mechanisms 3 are both located in the middle of the frame 2, and the two dust removal mechanisms 3 are arranged at intervals in the vertical direction; the transfer cylinder 4 is fixed to the middle of the frame 2, and the transfer cylinder 4 is located between the two dust removal mechanisms 3; the discharge cylinder 5 is fixed to the bottom of the frame 2, and the discharge cylinder 5 is located below the lower dust removal mechanism 3.

[0027] The two dust removal mechanisms 3 have the same size, structure and principle. Each dust removal mechanism 3 includes multiple conveying rollers 31, a conveyor belt 32, a cleaning roller 33 and a drive assembly 34. The multiple conveying rollers 31 are rotatably mounted on the frame 2 and are evenly spaced along the horizontal direction. The conveyor belt 32 is connected to the outer periphery of the multiple conveying rollers 31 and is a toothed conveyor belt 32. The outer periphery of the conveying rollers 31 is provided with toothed grooves that are adapted to the toothed conveyor belt 32. The cleaning roller 33 is rotatably mounted on the frame 2 and is arranged parallel to the conveying rollers 31. The cleaning roller 33 is located above the conveyor belt 32.

[0028] The drive assembly 34 is mounted on the frame 2 and is used to drive the conveyor roller 31 and the cleaning roller 33 to rotate. The drive assembly 34 specifically includes a motor 341 and a drive shaft 342; wherein, the drive shaft 342 is rotatably mounted on the frame 2, and the drive shaft 342, the conveyor roller 31 and the cleaning roller 33 are arranged perpendicular to each other, and the horizontal height of the drive shaft 342 is between the conveyor roller 31 and the cleaning roller 33; the motor 341 is fixed to the frame 2, and the output shaft of the motor 341 is coaxially connected to the drive shaft 342; one end of the conveyor roller 31 and one end of the cleaning roller 33 rotatably pass through the frame 2, and worm gears 343 are fixedly provided at the ends of the conveyor roller 31 and the cleaning roller 33, and a worm 344 adapted to connect with the worm gears 343 is fixedly provided on the outer periphery of the drive shaft 342, and the worm gear 343 at the end of the cleaning roller 33 and the worm gear 343 at the end of one of the conveyor rollers 31 are connected to the same worm 344. The starter motor 341 drives the drive shaft 342 to rotate. The drive shaft 342 is driven by the meshing of the worm gear 343 and the worm 344 to drive the conveyor roller 31 and the cleaning roller 33 to rotate, thereby realizing the rotation of the conveyor roller 31 and the cleaning roller 33 by the drive assembly 34.

[0029] Multiple evenly spaced mounting blocks 35 are fixed around the outer periphery of the conveyor belt 32, and a transition piece 36 made of rubber stretchable material is connected between the opposite sides of two adjacent mounting blocks 35. The transition piece 36 is flush with the side of the mounting block 35 away from the conveyor belt 32. The side of the mounting block 35 away from the conveyor belt 32 has a slot 37 that is adapted to be fitted with a copper plate. The slot 37 has openings on the left and right sides, and the width of the copper plate is greater than the width of the slot 37, so that the two sides of the copper plate pass through the left and right sides of the slot 37 respectively.

[0030] Reference Figure 2-4 The mounting block 35 has a clamping assembly 38 in the middle that abuts against both sides of the copper plate. The clamping assembly 38 specifically includes four synchronous gears 381, four connecting rods 382, ​​four clamping blocks 383, and elastic elements 384. The mounting block 35 has mounting holes 39 in the middle to provide mounting bases for the four synchronous gears 381 and elastic elements 384. The four synchronous gears 381 are rotatably mounted on a pre-set mounting shaft inside the mounting holes 39. The four synchronous gears 381 are arranged in a rectangular shape, and the two adjacent synchronous gears 381 are meshed with each other, as are the two adjacent synchronous gears 381 on the left and right sides, so that the four synchronous gears 381 can rotate simultaneously. The two adjacent synchronous gears 381 on the top and bottom and the two adjacent synchronous gears on the left and right sides rotate in opposite directions.

[0031] Four connecting rods 382 are arranged in a one-to-one correspondence with four synchronous gears 381. One end of each connecting rod 382 is fixed to the outer periphery of the corresponding synchronous gear 381. The four connecting rods 382 are arranged in an X-shape. The four connecting rods 382 are arranged symmetrically in pairs, that is, symmetrically arranged between two adjacent connecting rods 382 at the top and bottom, and between two adjacent connecting rods 382 at the left and right. When any connecting rod 382 drives the corresponding synchronous gear 381 to rotate, the four connecting rods 382 always maintain the above-mentioned symmetrical arrangement relationship under the interaction of the four synchronous gears 381.

[0032] Four clamping blocks 383 are arranged in a one-to-one correspondence with four connecting rods 382. Each clamping block 383 is located at the end of the corresponding connecting rod 382 away from the synchronous gear 381, and the top of each clamping block 383 is exposed on the outer periphery of the conveyor belt 32. The elastic element 384 is a tension spring. The elastic element 384 is connected between two adjacent connecting rods 382 on the left and right sides, so that the four clamping blocks 383 always have a tendency to move closer to the conveyor belt 32 under the drive of the four connecting rods 382 and the four synchronous gears 381, so that the four clamping blocks 383 can abut against the two sides of the copper plate in pairs.

[0033] During the rotation of the drive assembly 34, the conveyor roller 31 and the cleaning roller 33 are driven by the drive assembly 34. The conveyor roller 31 drives the conveyor belt 32 to transport the installation block 35 and the clamping assembly 38, which are rotated in a cycle with the conveyor belt 32 and pass through the bottom of the loading cylinder 1.

[0034] In this embodiment, the depth of the slot 37 is less than the thickness of the copper plate. Specifically, the depth of the slot 37 is half the thickness of the copper plate. That is, after the bottom of the copper plate is embedded in the slot 37, the top of the copper plate is exposed on the top of the mounting block 35. The inner contour of the feeding cylinder 1 is adapted to the outer contour of the copper plate. The distance between the bottom of the feeding cylinder 1 and the top of the mounting block 35 is less than the thickness of the copper plate. Specifically, the distance between the bottom of the feeding cylinder 1 and the top of the mounting block 35 is four-fifths of the thickness of the copper plate. That is, when the bottom of the copper plate slides into contact with the top of the mounting block 35 / the top of the transition piece 36, the top of the copper plate is still located inside the bottom of the feeding cylinder 1. After the bottom of the copper plate is embedded in the slot 37, the top of the copper plate is removed from the bottom of the feeding cylinder 1.

[0035] A support member 6 is fixed on one side of the feeding cylinder 1 opposite to the conveyor belt 32 in the conveying direction. The support member 6 is similar to an isosceles triangle structure. Since the four clamping blocks 383 can be paired up and abut against the two sides of the copper plate, and the top of each clamping block 383 is exposed on the outer periphery of the conveyor belt 32, when the mounting block 35 and the clamping assembly 38 are circulated with the conveyor belt 32 and pass through the bottom of the feeding cylinder 1, the tip of the support member 6 can penetrate between two clamping blocks 383, so that the clamping blocks 383 on both sides of the conveyor belt 32 slide in contact with the support member 6. The clamping blocks 383 overcome the elastic force of the elastic member 384 and open with force. Subsequently, the clamping blocks 383 continue to slide in contact with the feeding cylinder 1, and when the clamping blocks 383 slide away from the feeding cylinder 1, the clamping blocks 383 are subjected to the elastic force of the elastic member 384 and return to clamping.

[0036] A feed plate 7 is fixedly arranged at an incline on one side of the transfer cylinder 4, which is opposite to the conveyor belt 32 in the conveying direction. The feed plate 7 has a support opening at the end away from the transfer cylinder 4, which slides in contact with the clamping block 383, so that the end of the feed plate 7 away from the transfer cylinder 4 forms an isosceles trapezoidal structure. Similar to the principle of the support 6, the front end of the feed plate 7 can pass between the two clamping blocks 383, so that the clamping blocks 383 on both sides of the conveyor belt 32 slide in contact with the feed plate 7. The clamping blocks 383 overcome the elastic force of the elastic element 384 and open with stored force. Then, the clamping blocks 383 continue to slide in contact until they are separated from the feed plate 7. At this time, the clamping blocks 383 are subjected to the elastic force of the elastic element 384 and return to clamping.

[0037] This application embodiment includes a feeding cylinder 1, two dust removal mechanisms 3, a transfer cylinder 4, and a discharging cylinder 5. The feeding method between the feeding cylinder 1 and the top dust removal mechanism 3, and the discharging method between the top dust removal mechanism 3 and the transfer cylinder 4 are disclosed above. It is worth mentioning that the feeding method between the transfer cylinder 4 and the bottom dust removal mechanism 3 is the same as the feeding method between the feeding cylinder 1 and the top dust removal mechanism 3, and the discharging method between the bottom dust removal mechanism 3 and the discharging cylinder 5 is the same as the discharging method between the top dust removal mechanism 3 and the transfer cylinder 4. Finally, by setting a material receiving port on one side of the discharging cylinder 5 and hinged a door on the side of the material receiving port, the multiple stacked copper plates collected by the discharging cylinder 5 after being discharged from the material receiving cylinder 5 can be taken out for packaging.

[0038] In this embodiment, each clamping block 383 includes a columnar block 91 and a rubber layer 92; wherein, the columnar block 91 is rotatably disposed at the end of the connecting rod 382, ​​and the rubber layer 92 is fixed to the outer periphery of the columnar block 91. The rubber layer 92 can increase the friction between the rubber layer and the copper plate, making the clamping action more stable.

[0039] Reference Figure 1 , 5 -6. In this embodiment, the cleaning roller 33 includes a fixed cylinder 331, a rotating cylinder 332, and multiple rows of cleaning bristles 333. The fixed cylinder 331 and the rotating cylinder 332 are arranged coaxially, and the rotating cylinder 332 is rotatably sleeved on the outer periphery of the fixed cylinder 331. The end of the fixed cylinder 331 away from the rotating cylinder 332 is fixed to the frame 2, while the end of the rotating cylinder 332 away from the fixed cylinder 331 is rotatably mounted on the frame 2. The worm gear 343 is fixed to the end of the rotating cylinder 332 away from the fixed cylinder 331, so that the rotating cylinder 332 is driven to rotate by the drive assembly 34. Multiple rows of cleaning bristles 333 are evenly fixed on the outer periphery of the rotating cylinder 332 along the center of the rotating cylinder 332. Each row of cleaning bristles 333 includes multiple cleaning bristles 333 arranged at equal intervals. An air jet hole 334 is opened on the outer periphery of the rotating cylinder 332 between two adjacent cleaning bristles 333 in the same row.

[0040] The fixed cylinder 331 has an air inlet 335 on its bottom side facing the conveyor belt 32. An air reservoir 336 is fixedly mounted on the inner circumference of the fixed cylinder 331 and is connected to the air inlet 335. The air reservoir 336 is made of rubber and has an expansion and air storage function. An air supply mechanism 8 connected to the air reservoir 336 is fixedly mounted on the frame 2, causing the air pressure in the air reservoir 336 to rise during expansion and air storage. A sealing ring 337 is fixedly mounted on the outer circumference of the fixed cylinder 331, fitting snugly against the inner wall of the rotating cylinder 332 and surrounding the air inlet 335. To ensure the coaxial arrangement of the rotating cylinder 332 and the fixed cylinder 331, a sealing groove is provided on the outer circumference of the fixed cylinder 331 for fixing the sealing ring 337.

[0041] During the rotation of the rotating cylinder 332, which drives the multiple rows of cleaning bristles 333, the fixed cylinder 331 rotates relative to the rotating cylinder 332, causing the air nozzle 335 to be misaligned with all the air holes 334 or aligned with one row of air holes 334. When the air nozzle 335 is misaligned with all the air holes 334, the air supply mechanism 8 maintains a constant inflation power to pump gas into the air storage bag 336, causing the air storage bag 336 to expand and store gas. Conversely, when the air nozzle 335 is aligned with one row of air holes 334, the high-pressure gas in the air storage bag 336 is rapidly ejected through the air nozzle 335 and the air holes 334 in sequence. The air nozzle 335 is located on the outer periphery of the fixed cylinder 331 facing the conveyor belt 32, so that the gas rapidly ejected from the air holes 334 blows off the dust on the front / back of the copper plate, complementing the cleaning bristles 333 and improving the cleaning effect.

[0042] The air supply assembly includes an air pump 81 fixed to the frame 2. The output end of the air pump 81 is connected to an air supply pipe 82. A one-way valve 83 is provided in the middle of the air supply pipe 82. The end of the air supply pipe 82 away from the air pump 81 passes through the fixed cylinder 331, and the end of the air supply pipe 82 away from the air pump 81 is connected to the air storage bladder 336. When the air pump 81 continuously outputs, gas is input into the air storage bladder 336 through the air supply pipe 82, causing the air storage bladder 336 to expand and store gas. The one-way valve 83 can minimize gas backflow and leakage.

[0043] Implementation Principle: During the operation of the dust removal device, in S10, the conveyor belt 32 of the top dust removal mechanism 3 drives the mounting block 35 to rotate and passes through the bottom of the feeding cylinder 1. The copper plate at the bottom of the feeding cylinder 1 is embedded in the slot 37 and detaches from the feeding cylinder 1 (at this time, the second to last copper plate is still located in the bottom of the feeding cylinder 1). During this process, the clamping block 383 of the clamping assembly 38, under the action of the spreading member 6, overcomes the elastic force of the elastic member 384 and opens with stored force. Then, when sliding away from the feeding cylinder 1, it returns to clamping on the left and right sides of the copper plate, so that the copper plate is fixed in the slot 37 of the mounting block 35, realizing the first gripping of the copper plate; in S20, the conveyor belt 32 drives the mounting block 35 to rotate and passes under the cleaning roller 33. The cleaning roller 33 cleans the front of the copper plate, realizing the front dust removal of the copper plate; in S30, the conveyor belt 32 drives the mounting block 35 to rotate and passes under the cleaning roller 33. The cleaning roller 33 cleans the front of the copper plate, realizing the front dust removal of the copper plate; in S30, the conveyor belt 32 drives the mounting block 35 to rotate and passes through the bottom of the cleaning roller 33. The cleaning roller 33 cleans the front of the copper plate, realizing the front dust removal of the copper plate; The moving mounting block 35 rotates to position the copper plate face down. Then, the clamping block 383 of the clamping assembly 38, under the action of the feeding plate 7, overcomes the elastic force of the elastic element 384 and opens, allowing the copper plate to fall freely from the slot 37 onto the inclined feeding plate 7. Finally, it slides down and is collected in the transfer cylinder 4, realizing the flipping and collection of the copper plate. In S40, the conveyor belt 32 of the bottom dust removal mechanism 3 drives the mounting block 35 to rotate and passes under the bottom of the transfer cylinder 4, repeating steps similar to S10, realizing the secondary gripping of the copper plate. In S50, the conveyor belt 32 drives the mounting block 35 to rotate and passes under the cleaning roller 33, repeating steps similar to S20, realizing the back dust removal of the copper plate. In S60, the conveyor belt 32 drives the mounting block 35 to rotate to position the copper plate face down, repeating steps similar to S30, realizing the feeding and collection of the copper plate.

[0044] The embodiments described herein are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
