[0028] An embodiment of the present utility model provides an adjustable electroplating hanger for a PCB board, as Figure 1-7 shown. The adjustable electroplating hanger for a PCB board includes: a frame body 1; a set of connecting blocks 2 slidably mounted on the frame body 1; a support net 3 fixedly mounted on the set of connecting blocks 2; a plurality of limiting blocks 4 respectively mounted on the frame body 1 and the support net 3 for limiting the PCB board; a plurality of positioning grooves 5 respectively opened on the frame body 1; a set of positioning frames 6 respectively rotatably mounted on one side of the set of connecting blocks 2, and the output rods of the set of positioning frames 6 are respectively adapted to the plurality of positioning grooves 5; and an auxiliary liquid drainage mechanism provided on the frame body 1 for draining the electroplating liquid on the frame body 1.

[0029] In this embodiment, when in use, first place the PCB board on a set of limiting blocks 4, and then adjust the support net 3 according to the size of the PCB board, so that the limiting blocks 4 on the support net 3 are in sliding contact with the PCB board. During the adjustment, first rotate the positioning frame 6 to make the positioning frame 6 rotate away from the positioning groove 5, and then slide the connecting block 2 so that the connecting block 2 slides along the support rod of the frame body 1, thereby driving the support net 3 to slide up and down by the connecting block 2, so that the limiting blocks 4 on the support net 3 are in contact with the PCB board. Then rotate the positioning frame 6 to make the output rod of the positioning frame 6 rotate into the adapted positioning groove 5 to fix the connecting block 2, and complete the adjustment operation of the support net 3. The adjustment is relatively fast;

[0030] After placing the PCB board so that it is located inside the frame body 1, after the PCB board is fixed, use a hoisting device to hoist the frame body 1 into the electroplating solution pool by the hoisting device, immerse the PCB board in the electroplating solution for electroplating operation. After electroplating, make the frame body 1 slide upward to the upper part of the pool body, and then start the auxiliary liquid discharge mechanism to drive the frame body 1 to tilt by the auxiliary liquid discharge mechanism, so that the excess electroplating solution in the frame body 1 is discharged, thereby reducing the waste of electroplating solution. Drive the support net 3 to slide through the connecting block 2, and then adjust the support net 3 up and down to adapt to PCB boards of different sizes, which can effectively improve the applicability of the frame body 1. Discharge the excess electroplating solution in the frame body 1 through the auxiliary liquid discharge mechanism, thereby effectively reducing the waste of electroplating solution.

[0031] In a further preferred embodiment of the present invention, baffles 7 are fixedly installed on both the frame body 1 and the support net 3, and a plurality of the baffles 7 are respectively located at the central positions of the support net 3 and the frame body 1, and a plurality of connecting blocks 8 are fixedly installed on each of the baffles 7.

[0032] In this embodiment, the PCB board is limited by the baffle 7 and the connecting block 8, so as to ensure that it will not break away from the limiting block 4, and the limiting effect is good.

[0033] In a further preferred embodiment of the present invention, connecting rods 9 are fixedly installed on one side of the connecting block 2, support plates 10 are arranged on one side of a group of the connecting rods 9, any one of the support plates 10 is hinged to the connecting rod 9, and a U-shaped plate 11 is slidably arranged on a group of the support plates 10.

[0034] In this embodiment, when placing the PCB board, first slide it into the limiting block 4 so that one side of the PCB board contacts the connecting block 8. After placing the PCB board, rotate the U-shaped plate 11 so that the clamping block in the U-shaped plate 11 contacts one side of the PCB board, so that the connecting block 8 and the clamping block are used in combination to limit the PCB board. By adjusting the U-shaped plate 11 and the connecting block 8 in combination to limit the PCB board, the installation of PCB boards of different sizes can be carried out, and the operation is relatively convenient.

[0035] In a further preferred embodiment of the present invention, an L-shaped plate 12 is fixedly installed on one side of the support plate 10, a fixing bolt 13 is threadedly installed on the L-shaped plate 12, and the fixing bolt 13 is threadedly connected to the connecting rod 9.

[0036] In this embodiment, the support plate 10 is fixed by the fixing bolt 13 to ensure that the U-shaped plate 11 will not move, which is beneficial to the fixing operation of the PCB board.

A slider 16 is slidably installed on the slide bar 15. The slider 16 is fixedly connected to the U-shaped plate 11. A connecting bolt 17 is threadedly installed on the U-shaped plate 11. The connecting bolt 17 is threadedly connected to the slider 16 and rotatably contacts the slide bar 15.

[0038] In this embodiment, when it is necessary to limit PCBs of different sizes, first place the PCB on the frame 1, then remove the connecting bolt 17 to enable the U-shaped plate 11 to slide freely. Then rotate the U-shaped plate 11 so that the support plate 10 rotates into contact with the connecting rod 9. Then fix the support plate 10. At the same time, according to the size of the PCB, slide the U-shaped plate 11 so that the clamping block in the U-shaped plate 11 slides into contact with one side of the PCB. When the U-shaped plate 11 slides, it drives the slider 16 to slide along the slide bar 15, thereby adjusting the U-shaped plate 11 to make the clamping block fit the PCB. Then use the connecting bolt 17 to fix the U-shaped plate 11. Drive the U-shaped plate 11 to slide through the slider 16, thereby adjusting the U-shaped plate 11, which is beneficial to the limiting operation of PCBs of different sizes by the U-shaped plate 11.

When the frame 1 tilts, the excess electroplating solution is discharged from one side of the frame 1, which can effectively reduce the waste of electroplating solution. Driving the arc plate 18 to rotate through the gear 21, thereby tilting the frame 1, can effectively discharge the excess electroplating solution in the frame 1, thus effectively reducing the waste of electroplating solution, and the use effect is good.
