Description

Technical Field

[0001] The invention relates to the technical field of copper clad laminate preparation, in particular to a preparation device and a preparation method for a polyimide copper clad laminate. Background Art

[0002] With the development of science and technology, higher requirements are placed on the performance of circuit boards. Polyimide has excellent high and low temperature resistance, good mechanical properties and chemical stability, and a small thermal expansion coefficient. Therefore, flexible copper-clad laminates made of polyimide materials covered with metal copper are widely used in electronic products.

[0003] Copper clad laminate is a basic material formed by laminating copper foil and insulating substrate. During the preparation process, a specific circuit pattern needs to be formed on the copper clad laminate to meet the needs of electronic equipment for circuit connection. During the preparation process, a layer of oxide may form on the surface of the copper clad laminate or be contaminated with oil, fingerprints and other dirt. These oxides and dirt will affect the quality of circuit engraving, such as reducing the etching speed of the etching solution and causing uneven etching. In order to avoid this situation, it is usually necessary to use liquids such as detergents to cooperate with polishing to clean the oxides on the surface of the copper clad laminate. After cleaning, it is necessary to rinse the cleaning agent with clean water. However, the existing copper clad laminate polishing and cleaning device has a relatively single function and can only perform the polishing function alone. When these cleaning agents need to be added, they usually need to be added manually, or multiple external pipes are connected to cooperate with the polishing device for cleaning. Manual cleaning is time-consuming and labor-intensive, affecting the circuit printing and engraving efficiency of the entire copper clad laminate, and the external pipes need to add additional control devices to regulate the discharge and replacement of different liquids, increasing the production equipment cost of the entire copper clad laminate.

[0041] The outer sleeve 22 is slidably connected to the inside of the dripping tube 17, and slide grooves 16 corresponding to the dripping tube 17 are provided on both sides of the truncated table 13. The end of the dripping tube 17 slides through the inside of the agent storage box 46, and the end of the dripping tube 17 located inside the agent storage box 46 is sealed.

After the copper clad laminate is pressed and prepared in the pressing box 1, it will be transported to the polishing table 10 by the conveying roller 3. At this time, the clamping plates 47 located on both sides of the polishing table 10 will fix the copper clad laminate by electrically controlling the closure. When the copper clad laminate is fixed, the operator can control the position of the entire drive motor 8 through the universal bracket 5. When the position of the drive motor 8 is determined, the operator can extend the telescopic rod 11 to allow the grinding wheel 14 at the bottom of the round table 13 to contact the copper clad laminate that needs to be polished and cleaned. After the grinding wheel 14 contacts the surface of the copper clad laminate, the operator can turn on the drive motor 8 to drive the entire grinding wheel 14 to rotate through the telescopic rod 11 to polish the copper clad laminate.

[0043] Example 2: Please refer to Figure 1 - Fig.15 The present embodiment further illustrates the first embodiment, wherein the grinding and cleaning mechanism comprises an inner telescopic tube 19 arranged inside the truncated table 13, a cleaning wheel 20 is arranged at the end of the inner telescopic tube 19, a sliding cavity 28 is opened at the end of the inner telescopic tube 19, a liquid guide tube 18 is arranged in communication with the inner side wall of the sliding cavity 28, an end of the liquid guide tube 18 away from the sliding cavity 28 is connected to the inside of the water storage tank 4, push plates 31 are slidably connected to both sides of the sliding cavity 28, a return spring 32 is arranged on the push plate 31, the other end of the return spring 32 is fixedly connected to the outer side wall of the inner telescopic tube 19, a side magnetic block 35 is arranged on the outer side wall of the push plate 31, and a contact rod 48 is arranged at the end of the push plate 31 away from the side magnetic block 35.

[0044] A side plate 49 is provided inside the truncated table 13 , and a trigger magnet 33 and a contact magnet 34 are fixedly connected to the outer wall of the side plate 49 . The side magnetic block 35 has the same magnetic poles as the trigger magnet 33 and the contact magnet 34 .

[0045] A pressure rod 29 is slidably connected inside the sliding cavity 28 , and pressure blocks 30 are fixedly connected on both sides of the pressure rod 29 . The pressure block 30 is in sliding contact with the contact rod 48 , and one end of the pressure rod 29 away from the pressure block 30 slides through the inside of the cleaning wheel 20 .

[0046] Both sides of the bottom of the sliding cavity 28 are connected with a conduit 36, and the other end of the conduit 36 ​​passes through the interior of the cleaning wheel 20. Both sides of the cleaning wheel 20 are fixedly connected with a mounting plate 37, and a plurality of branch pipes 38 are provided on the mounting plate 37. The upper ends of the plurality of branch pipes 38 are connected to the interior of the conduit 36. A connecting box 39 is provided on the plurality of branch pipes 38. The inner side walls of the plurality of connecting boxes 39 are slidably connected with a slide plate 40 together. A through hole 41 is opened on the slide plate 40. The end of the slide plate 40 is rotatably connected with a swing arm 42, and the end of the swing arm 42 away from the slide plate 40 is rotatably connected to the outer wall of the pressure rod 29.

[0047] A storage box 43 is provided inside the cleaning wheel 20, and an adsorption sponge 44 is slidably connected to the inner wall of the storage box 43. A heater is provided inside the storage box 43. The lower end of the pressure rod 29 passes through the interior of the storage box 43 and is connected to the adsorption sponge 44. The lower end of the pressure rod 29 is sleeved with a pressure spring 45.

[0048] In this embodiment, when the grinding wheel 14 is in contact with the copper-clad laminate, the temperature of the surface of the grinding wheel 14 will become higher and higher under the action of friction. At this time, under the conduction of the heat-conducting strip 15, the heat will enter the inside of the truncated table 13 (it should be noted that the heat-conducting strip 15 is made of brass material and has a strong thermal conductivity). After the heat-conducting strip 15 conducts the heat generated on the surface of the grinding wheel 14 to the inside of the truncated table 13, the heat-absorbing member 25 in contact with the surface of the heat-conducting strip 15 will conduct the heat to the inside of the top rod 21. The mercury in the top rod 21 will undergo a thermal expansion reaction after sensing the higher heat, thereby pushing the slide bar 26 to overcome the elastic force of the pressing spring 27 and move upward. When the slide bar 26 is pushed up, it will push the drip plate 24 through the connecting plate The sprinkler pipe 17 moves toward the interior of the agent storage box 46, allowing the through hole 23 originally located outside the agent storage box 46 to enter the agent storage box 46. When the through hole 23 enters the inside of the agent storage box 46, the detergent stored in the agent storage box 46 will enter the inside of the drip sprinkler pipe 17 through the through hole 23, and then flow to the outside of the grinding wheel 14 through the delivery flow of the drip sprinkler pipe 17, and cooperate with the grinding of the grinding wheel 14 to clean the oxide and other dirt on the surface of the copper clad laminate. The grinding wheel 14 first generates heat by grinding the copper clad laminate, which can soften the heat transfer oil, lubricant and other stains remaining on the surface of the copper clad laminate. These stains and impurities will become easier to remove after being heated, providing a better cleaning basis for the subsequent spraying of the detergent, making the cleaning effect more thorough.

[0049] When the grinding wheel 14 has finished cleaning the surface of the copper-clad laminate, the operator can control the telescopic rod 11 to slightly retract, so that the grinding wheel 14 is away from the contact with the surface of the copper-clad laminate, and then extend the inner telescopic tube 19, so that the inner telescopic tube 19 pushes the cleaning wheel 20 to move a short distance to the outside of the round table 13. When the inner telescopic tube 19 is extended to push the cleaning wheel 20 to move a short distance to the outside of the round table 13, the push plate 31 will also be driven to move synchronously until it moves to the right side of the trigger magnet 33. When the push plate 31 is located at the right side of the trigger magnet 33, Under the repulsive magnetic force of the side magnetic block 35 and the trigger magnet 33, the push plate 31 will overcome the elastic force of the reset spring 32 and push the contact rod 48 to move into the sliding cavity 28, and squeeze and push the pressing block 30. When the pressing block 30 is squeezed and pushed by the two contact rods 48, the pressing rod 29 will be pushed to move down a distance inside the cleaning wheel 20. When the pressing rod 29 moves down, it will push the swing arm 42 to flip to both sides, thereby pushing the slide plate 40 to move to the outside of the cleaning wheel 20. When the slide plate 40 moves to the outside of the cleaning wheel 20, it will push the through hole 41 into the connection box 39 (such as Fig.10 As shown in the figure, since the liquid conduit 18 is connected to the water storage tank 4, the water in the water storage tank 4 will enter the sliding cavity 28 through the liquid conduit 18, and then enter each branch pipe 38 through the conduit 36.

[0050] As shown in the above principle, when the through hole 41 enters the connection box 39, the water in the upper side of the branch pipe 38 will flow to the lower side of the branch pipe 38 through the through hole 41, and finally flow to the outside of the cleaning wheel 20, and cooperate with the high-speed rotating cleaning wheel 20 to clean the dirt and cleaning liquid residue polished off the surface of the copper clad laminate. When the surface of the copper clad laminate is cleaned, the operator can extend the inner telescopic tube 19 again to push the cleaning wheel 20 to move to the outside of the truncated table 13 again. When the inner telescopic tube 19 is extended again, it will push the push plate 31 to the side of the contact magnet 34. Since the magnetic force of the contact magnet 34 is stronger than that of the trigger magnet 33, the larger the contact magnet 34 is, the smaller the contact magnet 34 is. Under the action of the repulsive magnetic force, the two push plates 31 will move a greater distance into the sliding cavity 28, and the corresponding contact rod 48 will greatly squeeze the pressing block 30 again along the inclined surface of the pressing block 30. When the pressing block 30 is greatly squeezed, the pressing rod 29 will move a greater distance into the cleaning wheel 20. When the pressing rod 29 moves a greater distance into the cleaning wheel 20, the flip angle of the swing arm 42 will increase, and the corresponding slide plate 40 will move a greater distance to the outside of the cleaning wheel 20. When the slide plate 40 moves a greater distance to the outside of the cleaning wheel 20, the through hole 41 will move out of the connection box 39, and the connection box 39 will be blocked again by the unopened part of the through hole 41 (such as Fig.11As shown), when the pressing block 30 blocks the connection box 39, the branch pipe 38 will stop spraying water outward, and the pressure rod 29, which moves downward significantly, will also press the adsorption sponge 44 to allow the adsorption sponge 44 to emerge from the storage box 43 until it contacts the surface of the copper clad laminate. The rotating cleaning wheel 20 can adsorb and scrape the water stains on the surface of the copper clad laminate to avoid residual water stains on the surface of the copper clad laminate, which affects the subsequent circuit printing. When the copper clad laminate is cleaned, it will be transported to the engraving table 9 through the conveying device inside the polishing table 10. At this time, the clamping plates 47 on both sides of the engraving table 9 will close to clamp the copper clad laminate, and then the engraver 7 will print the circuit on the copper clad laminate, thereby completing the preparation process of the copper clad laminate (the above are all prior art and will not be elaborated on in detail).

[0051] A method for preparing a polyimide copper-clad laminate, the method comprising the following steps:

[0052] S1, when in use, the pressing box 1 will first press the copper clad laminate, and when the copper clad laminate is prepared in the pressing box 1, it will continue to be cut into the required size in the pressing box 1;

[0053] S2, when the copper clad laminate is pressed and prepared in the pressing box 1, it will be transported to the grinding table 10 by the conveying roller 3. At this time, the clamping plates 47 on both sides of the grinding table 10 will fix the copper clad laminate by electric control closure. When the copper clad laminate is fixed, the grinding wheel 14 will grind the copper clad laminate;

[0054] S3, when the grinding wheel 14 finishes grinding and cleaning the surface of the copper clad laminate, the inside of the truncated table 13 sprays water to clean the surface of the copper clad laminate;

[0055] S4, the cleaned copper clad laminate will be transported to the engraving table 9, and the engraver 7 will print the circuit, thereby completing the copper clad laminate preparation process.

[0056] It should be noted that the size of the existing copper-clad boards used to make circuit boards is usually small, with the maximum size not exceeding ten centimeters. The ratio of the size of the copper-clad board to the size of the grinding wheel 14 is as follows: Fig.15 As shown, therefore, the detergent and water in the agent storage box 46 and the water storage tank 4 can clean multiple batches of copper clad laminates.

[0057] It should also be noted that the adsorption sponge 44 is made of polyurethane, which is a high-performance water-absorbing material. The adsorption sponge 44 made of polyurethane can absorb water several times its own weight, and when the entire device has completed polishing the copper-clad laminate, the adsorption sponge 44 will return to the storage box 43 and be dried by the heater in the storage box 43.

[0058] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
