Description

Technical Field

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

[0002] PCB, or printed circuit board, plays a vital role in the production of printed circuit boards. By applying an electrolyte containing copper ions in the plating tank and using electrolysis to evenly deposit a layer of copper foil on the surface of the PCB, the copper foil can significantly improve the conductivity, corrosion resistance and welding performance of the circuit board, ensuring the stability and reliability of the circuit connection.

[0003] Patent CN222182524U discloses a copper plating device for high aspect ratio circuit boards, which controls the up and down movement of the mechanical claw through the electric telescopic rod three, and the electric telescopic rod four controls the fixed plate two to adapt to circuit boards of different widths, thereby achieving the effect of grabbing circuit boards of different specifications and then electroplating them.

[0004] In the technical solution of the above-mentioned 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, the circuit board will bend due to liquid flow or circuit board movement during the electroplating process. Therefore, the circuit board needs to be fixed at multiple points. On this basis, since the length-to-width ratios of circuit boards of different specifications are different, it can only adapt to circuit boards of different widths, but cannot adapt to circuit boards of different heights. There are certain deficiencies when electroplating circuit boards of more different specifications. Summary of the invention

[0005] The purpose of the present invention is to provide a loading and unloading device for an electroplating system to solve the technical problems in the prior art, in which the circuit board is easily damaged during electroplating and circuit boards of more specifications cannot be further hoisted because the clamp can only clamp and fix one side of the circuit board and cannot clamp circuit boards of different heights.

[0029] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below: The loading process includes the following steps: A100: First, use the crane 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 can provide limited support to 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 lateral electric cylinder 3023 to move the clamping claw cylinder 3025 to the appropriate position, and then use the clamping claw cylinder 3025 to fix the adjustment clamping plate 2035; because the adjustment rod 2036 and the adjustment clamping plate 2035 are both connected to the hanging plate 202, the clamping claw cylinder 3025 actually clamps the adjustment rod 2036; the lateral electric cylinder 3023 continues to move, and with the help of the detection light curtain 106 below, the moving distance of the lateral electric cylinder 3023 (that is, the current width of the loading plate) is measured; after reaching the preset position, the lateral electric cylinder 3023 stops, and the clamping claw 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 realizing the 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 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; 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; 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; A900: Use the crane arm to lift the hanging plate 202 out of the limiting seat 201, and then repeat the above steps.

[0030] The following steps are included in the unloading process: B100: Use the crane arm again to move the hanging plate 202 horizontally to the specified 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: 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; 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 close the third top clamping cylinder 304 and the supporting cylinder 3022 in turn 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.

[0031] In step B400, the lifting platform 307 is equipped with a metal sensor; when the lifting platform 307 rises and senses the metal guide rod, it stops, thereby determining the position of the slide bar 203; the sensing distance of the metal sensor is set between 1mm-2mm.

[0032] Through the coordinated action of the supporting cylinder 3022 and the second top clamping cylinder 303, and the cooperation between the second top clamping cylinder 303 and the third top clamping cylinder 304, a balanced force can be applied to the upper and lower parts of the slide bar 203. This not only achieves force balance, but also effectively prevents the slide bar 203 from deflecting or bending when pressure is applied to the upper clamping head 2032 and the lower clamping head 2031, thereby playing a protective role and ensuring the stable operation of the circuit board during the electroplating process.

[0033] Among them, through the cooperation of the upper clamp 2032 and the lower clamp 2031, the upper and lower four corners of the circuit board can be fixed and clamped at the same time to ensure that the circuit board will not be bent or damaged during the electroplating process. In addition, by using the detection light curtain 106 in conjunction with the adjustment rod 2036 and the sliding rod 203, the distance between the upper clamp 2032 and the upper clamp 2032, between the lower clamp 2031 and the lower clamp 2031, and between the upper clamp 2032 and the lower clamp 2031 can be adjusted to adapt to more circuit boards of different specifications and have higher practicality.

10. The loading and unloading device for an electroplating system according to claim 1, 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.
