Description

Technical Field

[0001] This utility model relates to the technical field of printed circuit board processing equipment, specifically to a quick-installation expandable vertical copper plating wire hanging basket. Background Technology

[0002] Immersion copper is short for chemical copper plating, which refers to the chemical deposition of a thin layer of copper onto the non-conductive hole walls of a pre-drilled substrate, serving as a base for subsequent electroplating. Immersion copper is a crucial step in PCB manufacturing, and its quality directly affects the performance of the PCB.

[0003] The existing copper plating process mainly involves placing several PCBs into a copper plating basket, which is then connected to a frame via an overhead crane. The crane lifts the basket and moves it above a copper plating tank filled with copper plating solution. The basket is then lowered, its frame resting on a vibration device mounted on the tank. At this point, the bottom of the basket is in contact with the bottom of the tank, immersing the PCBs in the solution. The vibration device is then activated, causing the basket to vibrate, which in turn vibrates the PCBs. This vibration improves mass transfer, eliminates air bubbles within the holes, and enhances the uniformity of copper plating within the holes, thereby improving the reliability of the PCB hole metallization. After a thin layer of copper has deposited on the hole walls, the basket is removed from the tank. The structure of the copper plating basket affects the number of PCB components that can be inserted and their stability, thus impacting production capacity and the quality of the copper plating.

[0004] The purpose of this invention is to provide a quick-installation, expandable vertical copper plating wire basket that can improve production capacity and copper plating quality. Utility Model Content

The slots of the first positioning plate 2 and fourth positioning plate 8 are used to clamp the bottom and top edges of the circuit board, respectively, while the slots of the second positioning plate 3 and third positioning plate 6 are used to clamp the opposite sides of the circuit board. The circuit board is fixed by the slots, and each slot corresponds to one circuit board, preventing the circuit board from slipping or stacking during the copper plating process.

[0031] In this embodiment, the frame 1 includes a bottom frame 11 with a quadrilateral structure, a first side rod 12, a second side rod 13, a third side rod 14 and a fourth side rod 15 connected to the four corners of the bottom frame 11 in sequence, and a top frame 16 for connecting the tops of the first side rod 12, the second side rod 13, the third side rod 14 and the fourth side rod 15.

[0032] Please see Figure 2 ,yes Figure 1 A schematic diagram of the first positioning plate from another angle. There are multiple first positioning plates 2, which are spaced apart in the horizontal direction. Each first positioning plate 2 is provided with multiple first slots 21, and the opening direction of the first slots 21 is upward. The slots on each first positioning plate 2 are one-to-one and are used to clamp the bottom edge of the circuit board, so that the bottom edge of each circuit board corresponds to multiple clamping points, which can improve the stability of the circuit board.

[0033] Please see Figure 3 ,yes Figure 1A schematic diagram of the second positioning plate from another angle. Multiple second positioning plates 3 are fixed to opposite sides of the frame 1 and are spaced apart vertically. Specifically, multiple spaced second positioning plates connect the first side rod 12 and the second side rod 13, and similarly, multiple spaced second positioning plates connect the third side rod 14 and the fourth side rod 15. Each second positioning plate 3 has multiple second slots 31, with the openings of the second slots 31 in the horizontal direction and facing inwards towards the basket, used to clamp one side of the circuit board. In this embodiment, each second positioning plate 3 has a one-to-one correspondence of the second slots 31, so that each circuit board's side corresponds to multiple clamping points, improving the stability of the circuit board.

[0034] The positioning rod 4 is fixed at both ends to opposite sides of the frame 1 for mounting the third positioning plate 6, which clamps the sides of the circuit board. Specifically, multiple sliders 5 are slidably connected to the positioning rod 4, and the third positioning plate 6 is connected to the sliders. The position of the third positioning plate 6 is adjusted by moving the sliders according to the size of the circuit board. Please refer to [link to relevant documentation]. Figure 4 ,yes Figure 1 A schematic diagram of the third positioning plate from another angle. The third positioning plate 6 is provided with multiple third slots 61, and the opening direction of the third slots 61 is horizontal. Each slot on the third positioning plate 6 corresponds one-to-one with the slot on the second positioning plate, and is used to clamp the other side of the circuit board.

[0035] Preferably, the positioning rods 4 are distributed in 2-3 layers in the vertical direction, and each layer of positioning rods is provided with multiple sliders 5 and a third positioning plate 6, so that the circuit board has multiple clamping points in the vertical direction to ensure the stability of the circuit board.

[0036] In this embodiment, two positioning rods 4 are connected between the first side rod 12 and the fourth side rod 15, and two positioning rods 4 are connected between the second side rod 13 and the third side rod 14. At least two sliders 5 are slidably connected to each positioning rod.

The fourth slot of the fourth positioning plate limits the corresponding circuit board. Then, the connecting rod is rotated so that the hook is attached to the frame, thus completing the positioning of the top edge of the circuit board by the fourth positioning plate. In this embodiment, Figure 1 The diagram only shows one fourth positioning plate; the number of fourth positioning plates connected to the frame can be increased according to the number of extended sub-baskets.

[0044] In this invention, the spacing H of the first, second, third, and fourth slots is 0.8-0.9 cm, meaning the spacing between adjacent slots on the first, second, third, and fourth positioning plates is 0.8-0.9 cm. Furthermore, the first, second, third, and fourth slots correspond one-to-one, ensuring one slot corresponds to one circuit board. Optimizing the slot spacing ensures the stability of the mother basket structure and prevents board breakage during operation.
