Description

Automatic dry-wet copper foil electroplating wheel grinding machine

Technical Field

The utility model relates to a copper foil electroplating wheel grinds machine, especially relates to an automatic dry-wet type copper foil electroplating wheel grinds machine for grind the copper foil electroplating wheel surface of production electrolytic copper foil.

Background

The electrolytic copper foil is mainly applied to printed circuit board conductors and lithium battery negative electrode collectors. The manufacturing flow of the electrolytic copper foil is shown in FIG. 1. A rotating copper foil electroplating wheel 1 is used as a cathode, the lower part of the copper foil electroplating wheel 1 is immersed in copper sulfate plating solution for high-speed electroplating, and the thickness of the copper foil is controlled by controlling the rotating speed of the copper foil electroplating wheel 1. After electroplating, the electrolytic copper foil 2 is stripped and rolled from the surface 3 of the copper foil electroplating wheel 1 to form a raw foil, and then the raw foil is subjected to surface treatment to form the copper foil. The roughness of the surface (S-surface) of the electrodeposited copper foil 2 adjacent to the copper foil plating wheel 1 depends on the roughness of the surface 3 of the copper foil plating wheel 1, and the surface 3 of the copper foil plating wheel 1 is uneven due to corrosion or the introduction of impurities in the air, so that the roughness of the S-surface gradually fails to the standard after a certain period of mass production. Therefore, the control of the roughness of the surface 3 of the copper foil plating wheel 1 is required to be performed frequently, and the most common action is to polish the surface 3 of the copper foil plating wheel 1.

Therefore, the mainstream sanding work is carried out accompanying the machine table itself. For the prior art, please refer to fig. 2, which discloses the technical content of taiwan new patent No. M581029. The M581029 patent discloses an automatic wet copper foil polishing machine, which can be installed beside a copper foil electroplating wheel 1 for operation. The machine station uses a water supply device 4 to carry out pre-wetting operation on a grinding wheel 5, and the grinding wheel 5 is pushed to a copper foil electroplating wheel 1 through the matching action of a traveling mechanism 6 and a motor 7, and the grinding wheel 5 is pulled back after finishing the grinding operation, so that the copper foil electroplating wheel 1 continues to operate. The waste water produced in the grinding process is easy to pollute the working environment, so that the machine table is provided with a water discharge groove 8 for guiding the waste water and discharging the waste water through at least one water discharge hole 9. The machine is fixed on the ground by a base 10, and the automatic operation is managed by an automatic control system 11.

In practice, the M581029 patent suffers from several problems. First, the motor 7 and the traveling mechanism 6 are used to control the grinding wheel 5 to advance and retreat without a feedback mechanism. Due to handling or mechanical errors, the surface of the grinding wheel 5 is not in parallel contact when contacting the surface 3 of the copper foil plating wheel 1, but has a slight angular difference. This causes excessive polishing of the surface 3 of the copper foil plating wheel 1 and also excessive consumption of the corresponding polishing wheel 5. The water supply device 4 performs the pre-wetting operation only for the polishing wheel 5, and the polishing water required for the copper foil plating wheel 1 during the polishing process needs to be separately supplied. Finally, because the abrasion degree of the surface of the grinding wheel 5 is different, in order to enable the surface 3 of the copper foil electroplating wheel 1 to be uniformly polished, the grinding wheel 5 can preferably dynamically adjust the relative position of the grinding wheel 5 and the copper foil electroplating wheel 1 during polishing in the rotating process. However, this is not mentioned in the art.

Since the prior art has the aforementioned points to be improved, the present invention has been developed to improve the deficiencies thereof.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention belong to the protection scope of the present invention.

Please refer to fig. 3, which is a diagram of an automatic dry and wet copper foil electroplating wheel grinding machine according to an embodiment of the present invention, including a base 100, a grinding wheel 110, a grinding wheel rotating module 200, a first driving and reversing grinding wheel module 300, a fine-tuning driving and reversing grinding wheel module 400, a second driving and reversing grinding wheel module 500, a grinding wheel vibrating module 600, a cover protecting module 700, a water supply module 800 and an automatic control module 900. The functions, detailed components and interaction relationships of these technical elements will be described below.

The base 100 is a base (not including the automatic control module 900) for supporting most of the machine components, and is rigid and flat (a plurality of height adjustment structures may be disposed under the base to adjust the flatness, not shown). In terms of material, stainless steel plate may be used.

Referring to fig. 3 and 5, the polishing wheel 110 is a tool for polishing a copper foil plating wheel. The grinding wheel 110 has a cylindrical grinding body 111 and a rotating shaft 112 penetrating the cylindrical grinding body 111, and the rotating shaft 112 has a first shaft end 1121 and a second shaft end 1122.

Please refer to fig. 3 and fig. 6. After removing a part of the machine housing in fig. 3, the detailed structure of the grinding wheel rotating module 200 can be clearly seen. The grinding wheel rotation module 200 is connected to the first shaft end 1121 and functions to control the rotation (including the rotation speed) and stop of the grinding wheel 110. The grinding wheel rotating module 200 includes a first n-shaped high-strength base 201, a first variable frequency motor 202, a first hollow speed reducer 203, a first belt pulley 204, a second belt pulley 205, a first timing belt 206, two third low-clearance angle-fixed slide rails 207, and a first automatic centering bearing 208. The first n-shaped high-strength base 201 can move on the two first low-clearance angle-fixed sliding rails 304 through the sliding blocks arranged below. The first hollow speed reducer 203 is connected to the first variable frequency motor 202 and is mounted on the first n-shaped high strength base 201. The combination of the first inverter motor 202 and the first hollow speed reducer 203 can adjust the rotation speed and the output power of the rotating shaft 2031 of the first hollow speed reducer 203. The first pulley 204 is connected to the first shaft end 1121 at the center thereof, and the second pulley 205 is connected to the rotating shaft 2031 of the first hollow speed reducer 203. A first timing belt 206 connects the first pulley 204 with the second pulley 205. When the rotating shaft 2031 rotates, the first timing belt 206 is pulled to rotate by the second pulley 205, thereby rotating the first pulley 204. Two third low clearance angle-fixing type sliding rails 207 are installed on the first n-shaped high strength base 201. The extending direction of each third low clearance angle-fixed slide 207 is substantially perpendicular to the first low clearance angle-fixed slide 304. That is, the moving direction of the component on the third low clearance angle-fixed slide 207 is substantially perpendicular to the moving direction of the component on the first low clearance angle-fixed slide 304. It is noted that although only one third low clearance angle-fixed slide 207 is shown in fig. 6, in reality, the other third low clearance angle-fixed slide 207 is hidden by the first self-centering core-pair bearing 208 and cannot be drawn. The first automatic centering bearing 208 can move on the two third low clearance angle fixed slide rails 207 through the slide block installed at the lower part. The central portion of the first auto-centering bearing 208 embraces the shaft 112. That is, the first shaft end 1121 of the rotating shaft 112 rotates at the central portion thereof against the first pulley 204, and the rotating shaft 112 rotates in the first automatic centering bearing 208. However, the technical feature of the present invention is that the first shaft end 1121 can pull the first automatic centering seat 208 to reciprocate along the third low clearance angle fixed slide rail 207 (in the direction shown by the blank double arrow in fig. 6) when rotating. This design enables the grinding wheel oscillation module 600 to oscillate the grinding wheel 110 back and forth parallel to the surface of the copper foil electroplating wheel.

Please refer to fig. 3 and fig. 4. The first advancing/retreating grinding wheel module 300 is mounted on the base 100 and movably receives the grinding wheel rotating module 200, thereby controlling the linear advancing/retreating of the grinding wheel rotating module 200. The first feeding/discharging grinding wheel module 300 includes a first servo motor 301, a first speed reducer 302, a first low-clearance ball screw set 303, and two first low-clearance angle-fixed slide rails 304. The first reducer 302 is connected to the first servomotor 301. The first low-gap ball screw set 303 is connected to the first speed reducer 302 and the grinding wheel rotating module 200 (the end of the first low-gap ball screw set 303 is connected to the lower side of the first n-shaped high-strength base 201), and the first low-gap ball screw set 303 is driven by the first speed reducer 302 to adjust the position of the grinding wheel rotating module 200. The two first low-clearance angle-fixing type slide rails 304 are fixed on the base 100, and the extending direction of each first low-clearance angle-fixing type slide rail 304 is substantially parallel to the first low-clearance ball screw group 303, so that the force output by the first speed reducer 302 can be ensured to be only consumed in the friction between the grinding wheel 110 and the copper foil electroplating wheel, and the grinding wheel rotating module 200 only moves back and forth on the first low-clearance angle-fixing type slide rails 304.

Please refer to fig. 3 and fig. 8. The fine adjustment grinding wheel advancing and retreating module 400 is connected to the second shaft end 1122 for fine adjustment of the grinding wheel 110 to ensure that the surface of the grinding wheel is in contact with the surface of the copper foil electroplating wheel, and the stress of each part is similar, so that excessive grinding is not generated. The fine-tuning grinding wheel advancing and retreating module 400 includes a second n-shaped high-strength base 401, two fourth low-clearance angle-fixed slide rails 402, a fixing plate 403, a slide rail 404, a third servo motor 405, a third speed reducer 406 and a second automatic centering bearing 407. The second n-shaped high-strength base 401 can move on the two second low-clearance angle-fixed sliding rails 504 through the sliding blocks installed below. Fourth low clearance angle-fixed slide rails 402 (only one fourth low clearance angle-fixed slide rail 402 is shown in fig. 8, and the other is covered by a second hollow speed reducer 602 in front), are mounted on the second u-shaped high-strength base 401. The extending direction of each fourth low clearance angle-fixed slide rail 402 is substantially perpendicular to the second low clearance angle-fixed slide rail 504, so that the grinding wheel oscillation module 600 can oscillate the grinding wheel 110 back and forth in a direction parallel to the surface of the copper foil plating wheel without being affected by the second low clearance angle-fixed slide rail 504. The fixed plate 403 is movably disposed on the two fourth low clearance angle-fixed sliding rails 402 by the sliding blocks thereunder, and the sliding rails 404 are installed above the fixed plate 403. The sliding rail 404 extends substantially parallel to the second low clearance angle-fixed slide rail 504, i.e., the object moving by the sliding rail 404 moves substantially parallel to the second low clearance angle-fixed slide rail 504, which is a factor for finishing the fine adjustment of the grinding wheel 110. The third reducer 406 is connected to the third servomotor 405 and fixed to the second-u-shaped high-strength base 401. The second automatic centering bearing 407 can be movably disposed on the sliding rail 404 via a slider connected to the lower portion. The second automatic centering bearing 407 is connected to the third reduction gear 406, and is pushed and pulled by the third reduction gear 406 to finely adjust the position. Since the third speed reducer 406 is stationary with respect to the second n-shaped high-strength base 401, when the third speed reducer 406 pushes or pulls the second automatic centering bearing 407, the second automatic centering bearing 407 moves along the sliding rail 404 with respect to the second n-shaped high-strength base 401. Since the third speed reducer 406 is short in advance, the moving amount of the second automatic centering bearing 407 is small, and therefore the purpose of fine-tuning the grinding wheel 110 can be achieved. The second automatic centering bearing 407 partially embraces the shaft 112 at the center and allows the shaft 112 to rotate but not move in the axial direction. Since the second automatic core-aligning bearing 407 and the first automatic core-aligning bearing 208 simultaneously clamp the rotating shaft 112 and can synchronously move in the direction parallel to the surface of the copper foil electroplating wheel, the grinding wheel oscillation module 600 can normally operate. The operation of the fine adjustment grinding wheel module 400 will be described later.

Please refer to fig. 3 and fig. 4. The second grinding wheel module 500 is mounted on the base 100 and movably receives the fine adjustment grinding wheel module 400, so as to control the linear advance and retreat of the fine adjustment grinding wheel module 400. The second grinding wheel advancing and retreating module 500 includes a second servo motor 501, a second speed reducer 502, a second low clearance ball screw set 503 and two second low clearance angle-fixed slide rails 504. The second reduction gear 502 is connected to the second servomotor 501. The second low-clearance ball screw group 503 is connected to the second speed reducer 502 and the fine-tuning grinding wheel advancing and retreating module 400 (the end of the second low-clearance ball screw group 503 is connected to the lower part of the second n-shaped high-strength base 401), and the position of the fine-tuning grinding wheel advancing and retreating module 400 is adjusted by the driving of the second speed reducer 502. Two second low clearance angle-fixing sliding rails 504 are fixed on the base 100, and the extending direction of each second low clearance angle-fixing sliding rail 504 is substantially parallel to the second low clearance ball screw group 503. As with the first grinding wheel module 300, the force output from the second reducer 502 is only consumed by the friction between the grinding wheel 110 and the copper-clad wheel, and the fine adjustment grinding wheel module 400 only reciprocates on the second low-clearance angle-fixed slide rail 504.

Please refer to fig. 3 and fig. 7. The grinding wheel oscillation module 600 is mounted on the fine-tuning driving and reversing grinding wheel module 400, and operates to axially move the grinding wheel 110 back and forth. The grinding wheel oscillation module 600 includes a second variable frequency motor 601, a second hollow speed reducer 602, a cam set 603, a third belt pulley 604, a fourth belt pulley 605, and a second timing belt 606. The second hollow speed reducer 602 is connected to the second inverter motor 601 and is mounted on the second n-shaped high-strength base 401.

That is, the automatic control module 900 can control the power supply of the devices that need to be electrically driven, such as the first inverter motor 202, the first servo motor 301, and the first solenoid valve 803, so as to perform the polishing operation on the surface of the copper foil electroplating wheel according to a predetermined schedule. According to the present invention, the automatic control module 900 includes a case 901, a control panel 902, a power control system 903, an operation system 904 and a main power button 905. The casing 901 is the outermost portion of the automatic control module 900 for protecting the components therein and facilitating the operation of the user. The control panel 902 is disposed on the casing 901 for setting the setting mode (parameters) and displaying the operation status of each electrically connected module.

In accordance with the present invention, the fine-tuning grinding wheel module 400 utilizes the working current difference feedback of the first grinding wheel module 300 and the second grinding wheel module 500 to fine-tune the linear advance and retreat of the second shaft end 1122. Precisely, the fine tuning grinding wheel advancing and retreating module 400 utilizes the difference between the working currents of the first servomotor 301 and the second servomotor 501 to feed back to fine tune the third servomotor 405, so as to adjust the position of the second automatic centering bearing 407 relative to the copper foil plating wheel. For example, the operating current value of the first servomotor 301 is 0.3 ampere, and the operating current value of the second servomotor 501 is 1 ampere. The working current value is in direct proportion to the external force applied to the servo motor, and the difference value indicates that the over-polishing condition occurs. Therefore, the third servomotor 405 can fine-tune the second shaft end 1122 of the grinding wheel 110 in a predetermined course so that the contact pressure between the grinding wheel 110 and the copper foil plating wheel is uniform. Therefore, the computing system 904 can calculate the difference between the working currents of the first grinding wheel module 300 and the second grinding wheel module 500, and control the fine-tuning grinding wheel module 400 via the power control system 903 to fine-tune the linear advance and retreat (perpendicular to the surface of the copper-clad laminate) of the second shaft end 1122. The main power button 905 is electrically connected to the power control system 903, and the switch is used for turning on and off the power control system 903. Of course, the automatic control module 900 may also be configured with other function buttons, such as an alarm button (connected to an alarm), a start button (starting a preset full-automatic function), a sub-module control button, an emergency stop button, etc., which is not limited by the present invention.
