Description

Technical Field

[0001] The present invention belongs to the technical field of electroplating equipment, and particularly relates to a loading and unloading device for an electroplating system. Background Art

[0002] A PCB, that is, a printed circuit board, its electroplating process plays a crucial role in the production of printed circuit boards. By applying an electrolyte containing copper ions in an electroplating tank and relying on electrolysis, a layer of copper foil is evenly deposited on the surface of the PCB. The copper foil can significantly improve the electrical conductivity, corrosion resistance and welding performance of the circuit board, ensuring the stability and reliability of circuit connections.

[0003] Patent CN222182524U discloses a copper plating device for high aspect ratio circuit boards, which controls the up and down movement of a mechanical claw through an electric telescopic rod three, and controls a second fixing plate through an electric telescopic rod four to adapt to circuit boards of different widths, so as to achieve the effect of grasping and then electroplating circuit boards of different specifications.

[0004] In the technical solution of the above patent, the purpose of clamping circuit boards of different widths can be achieved by adjusting the position of the fixing plate. However, in actual applications, if only one side of the circuit board is fixed, it will cause the circuit board to bend during electroplating due to liquid flow or circuit board movement. Therefore, multiple points of fixation of the circuit board are required. On this basis, since the aspect ratios of circuit boards of different specifications are different, it can only adapt to circuit boards of different widths and cannot adapt to circuit boards of different heights, and there are certain deficiencies in electroplating more circuit boards of different specifications.

[0017] A200: Start the support cylinder so that the output end of the support cylinder can provide limited support to the inner side of the hanging plate;

[0018] A300: Activate the telescopic arm opening and closing cylinder, which pushes the fixed pressure plate open, releases the restriction on the adjustment rod, and allows the adjustment rod to slide horizontally;

[0051] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below:

[0052] The feeding process includes the following operation steps:

[0053] A100: First, use the jib to horizontally move the hanging plate 202 to the limit seat 201 on the second cross bar 102, and then fix the position of the hanging plate 202 through the limit seat 201;

[0054] A200: Start the support cylinder 3022 so that the output end of the support cylinder 3022 provides limit support to the inner side of the hanging plate 202;

[0055] A300: Activate the telescopic arm opening and closing cylinder 103, and use this cylinder to push open the fixed pressing plate 2037 to release the restriction on the adjusting rod 2036 and allow the adjusting rod 2036 to slide horizontally;

[0056] A400: Start the transverse moving electric cylinder 3023 to move the clamping jaw cylinder 3025 to an appropriate position, and then use the clamping jaw cylinder 3025 to fix the adjusting clamping plate 2035; since both the adjusting rod 2036 and the adjusting clamping plate 2035 are connected to the hanging plate 202, the clamping jaw cylinder 3025 actually clamps the adjusting rod 2036; the transverse moving electric cylinder 3023 continues to move, and with the help of the detection light curtain 106 below, measures the moving distance of the transverse moving electric cylinder 3023 (i.e., the current width size of the feeding plate); after reaching the preset position, the transverse moving electric cylinder 3023 stops, and the clamping jaw cylinder 3025 closes to release the clamping of the adjusting clamping plate 2035;

[0057] A500: After the adjusting rod 2036 moves to the specified dimension position, the telescopic arm opening and closing cylinder 103 closes, and the fixed pressing plate 2037 no longer receives the acting force and re-clamps the adjusting rod 2036 to ensure its stable position, thereby realizing the board width adjustment during the clamping of the circuit board;

[0058] A600: Start the lifting cylinder 104 to apply force to the limit claw 2033, so that the tail end of the claw is tilted and separated from the contact of the sawtooth 2034; at this time, the slide bar 203 begins to descend under the action of gravity until the bottom end falls on the upper surface of the lifting platform 307;

[0059] A700: Activate the adjusting cylinder 308, cooperate with the U-shaped plate 301 to make the lifting platform 307 rise, and drive all the slide bars 203 to move upward synchronously; when the slide bars 203 reach the required board height position, they stop moving and close the lifting cylinder 104; the lifting cylinder 104 re-applies force to the limit claw 2033 to make it contact with the sawtooth 2034, thereby limiting the position of the slide bar 203, and completing the board height adjustment when the circuit board is clamped;

[0060] A800: First, start the first top clamping cylinder 105 and the second top clamping cylinder 303, then start the third top clamping cylinder 304, so that the upper clamping head 2032 and the lower clamping head 2031 are fully opened; use the manipulator to grasp the circuit board and put it on; after the board is put on, first close the first top clamping cylinder 105 and the third top clamping cylinder 304, then close the second top clamping cylinder 303, and finally close the supporting cylinder 3022, and the circuit board loading operation can be completed;

[0061] A900: Use the crane arm to lift the hanging plate 202 out of the limiting seat 201, and then repeat the above steps.

[0062] The following steps are included in the unloading process:

[0063] B100: Use the crane arm again to move the hanging plate 202 horizontally to the specified position, and make it fall on the limiting seat 201, and use the limiting seat 201 to fix the position of the hanging plate 202;

[0064] B200: Start the supporting cylinder 3022 to effectively support the inner side of the hanging plate 202 through the output end of the supporting cylinder 3022 to prevent the first top clamping cylinder 105 from causing the position of the hanging plate 202 to shift during the pushing process;

[0065] B300: Regulate the cylinder 308 to make the lifting platform 307 rise. Once the detection light curtain 106 captures the position of the slide bar 203, the lifting stops immediately and the third top clamping cylinder 304 is activated;

[0066] B400: After determining the position of the slide bar 203, the manipulator moves to the surface of the circuit board and adsorbs the circuit board; then, the first top clamping cylinder 105 and the second top clamping cylinder 303 are activated, the upper clamp 2032 and the lower clamp 2031 are opened, and the circuit board is taken out by the manipulator and transferred to the conveying section to enter the next process;

[0067] B500: First, close the first top clamping cylinder 105 and the second top clamping cylinder 303, then successively close the third top clamping cylinder 304 and the support cylinder 3022 to restore to the initial state;

[0068] B600: Use the jib to take out the hanging plate 202 from the limit seat 201, and then the above operation steps can be repeated.

[0069] In step B400, a metal inductor is equipped on the lifting platform 307; when the lifting platform 307 rises and senses the metal guide rod, it will stop, thereby determining the position of the sliding rod 203; the sensing distance of the metal inductor is set between 1 mm and 2 mm.

[0070] Through the coordinated action of the support cylinder 3022 and the second top clamping cylinder 303, and the mutual cooperation between the second top clamping cylinder 303 and the third top clamping cylinder 304, balanced forces can be simultaneously applied to the upper and lower parts of the sliding rod 203. This not only achieves force balance but also effectively prevents the sliding rod 203 from shifting or bending when pressure is applied to the upper clamping head 2032 and the lower clamping head 2031, thus playing a protective role and ensuring the stable operation of the circuit board during electroplating.

[0071] Among them, through the joint cooperation of the upper clamping head 2032 and the lower clamping head 2031, the upper and lower four corners of the circuit board can be fixedly clamped simultaneously, ensuring that the circuit board will not be bent or damaged during electroplating. In addition, by using the detection light curtain 106 in cooperation with the adjusting rod 2036 and the sliding rod 203, the purpose of adjusting the distances between the upper clamping head 2032 and the upper clamping head 2032, between the lower clamping head 2031 and the lower clamping head 2031, and between the upper clamping head 2032 and the lower clamping head 2031 can be achieved, so as to adapt to more circuit boards of different specifications and have higher practicability.

A loading and unloading device for an electroplating system according to claim 8, characterized in that: The device includes the following loading operation steps: A100: Use the lifting arm to move the hanging plate (202) horizontally to the limiting seat (201) on the second crossbar (102), and then fix the position of the hanging plate (202) by the limiting seat (201); A200: Start the supporting cylinder (3022) so that the output end of the supporting cylinder (3022) performs position limiting support on the inner side of the hanging plate (202); A300: Activate the telescopic arm opening and closing cylinder (103), which pushes the fixed pressure plate (2037) open, releases the restriction on the adjustment rod (2036), and allows the adjustment rod (2036) to slide horizontally; A400: Start the traverse electric cylinder (3023) to move the clamping cylinder (3025) to an appropriate position, and then use the clamping cylinder (3025) to fix the adjustment clamping plate (2035); the traverse electric cylinder (3023) continues to move, and with the help of the detection light curtain (106) below, the movement distance of the traverse electric cylinder (3023) is measured; after reaching the preset position, the traverse electric cylinder (3023) stops, and the clamping cylinder (3025) is closed, releasing the clamping of the adjustment clamping plate (2035); A500: After the adjusting rod (2036) moves to the specified size position, the telescopic arm opening and closing cylinder (103) is closed, the fixed pressing plate (2037) is no longer subjected to the force, and the adjusting rod (2036) is clamped again to ensure its stable position, thereby achieving board width adjustment when the circuit board is clamped; A600: Start the lifting cylinder (104) to apply force to the limit claw (2033), so that the tail end of the claw is tilted and separated from the contact of the saw teeth (2034); at this time, the slide bar (203) begins to descend under the action of gravity until the bottom end falls on the upper surface of the lifting platform (307); A700: activating the regulating cylinder (308), cooperating with the U-shaped plate (301) to raise the lifting platform (307), driving all the slide bars (203) to move upward synchronously; when the slide bars (203) reach the desired board height position, they stop moving and close the lifting cylinder (104); the lifting cylinder (104) re-applies force to the limit claw (2033) to make it contact with the saw teeth (2034), thereby limiting the position of the slide bars (203), and completing the board height adjustment when the circuit board is clamped; A800: First, start the first top clamping cylinder (105) and the second top clamping cylinder (303), then start the third top clamping cylinder (304), so that the upper clamping head (2032) and the lower clamping head (2031) are fully opened; use the manipulator to grasp the circuit board and load it; after loading, first close the first top clamping cylinder (105) and the third top clamping cylinder (304), then close the second top clamping cylinder (303), and finally close the supporting cylinder (3022), so that the circuit board loading operation is completed; A900: Use the lifting arm to remove the hanging plate (202) from the limit seat (201), and then repeat the above steps.

10. The loading and unloading device for an electroplating system according to claim 8, characterized in that: The device includes the following unloading operation steps: B100: Use the crane arm again to move the hanging plate (202) horizontally to the designated position, and make it fall on the limit seat (201), and use the limit seat (201) to fix the position of the hanging plate (202); B200: Start the supporting cylinder (3022) to effectively support the inner side of the hanging plate (202) through the output end of the supporting cylinder (3022) to prevent the first top clamping cylinder (105) from causing the position of the hanging plate (202) to shift during the pushing process; B300: The cylinder (308) is adjusted to make the lifting platform (307) rise. Once the detection light curtain (106) captures the position of the slide bar (203), the lifting stops immediately and the third top clamping cylinder (304) is activated. B400: After determining the position of the slide bar (203), the manipulator moves to the surface of the circuit board and adsorbs the circuit board; then, the first top clamping cylinder (105) and the second top clamping cylinder (303) are activated, the upper clamp (2032) and the lower clamp (2031) are opened, and the circuit board is taken out by the manipulator and transferred to the conveying section to enter the next process; B500: First, close the first top clamping cylinder (105) and the second top clamping cylinder (303), and then successively close the third top clamping cylinder (304) and the supporting cylinder (3022) to restore to the initial state; B600: Use the lifting arm to remove the hanging plate (202) from the limiting seat (201), and then repeat the above steps.
