Description

Technical Field

[0001] The utility model belongs to the technical field of PCB board processing equipment, and particularly relates to a storage rack for chemical gold immersion of PCB boards. Background Art

[0002] Chemical gold immersion is a method of chemical deposition, which generates a metal coating on the surface of a circuit board through a chemical oxidation-reduction reaction. This process first replaces a layer of palladium on the copper substrate of the circuit board as a catalytic core through a chemical reaction. Subsequently, in a plating solution containing nickel salt and a reducing agent, a nickel-phosphorus alloy layer is formed on the palladium core through an electrochemical reaction. Finally, a layer of gold is plated on the nickel-phosphorus alloy layer through a displacement reaction to form a complete gold immersion layer.

[0003] At this time, the PCB board has not been cut, so the board is very large. To improve efficiency, generally, multiple boards are placed together for processing. However, the current fixing rack can only fit one model and cannot match multiple specifications. At the same time, during chemical processing, the manipulator will drive the storage rack to move back and forth, and there will be a situation of unhooking. Content of the Utility Model

[0004] To solve the above technical problems, a technical solution adopted by the utility model is:

[0005] A storage rack for chemical gold immersion of PCB boards includes a frame body and a side wall fixing component fixed on the frame body. A top fixing component is also slidably connected to the frame body, and a hook component is connected thereto;

[0006] The frame body includes an upper frame, a lower frame, and vertical rods disposed between the upper frame and the lower frame. The vertical rods are divided into a first vertical rod, a second vertical rod, and a limiting member. The first vertical rod and the second vertical rod are sleeved with each other, the first vertical rod slides in the second vertical rod, and the limiting member is provided on the second vertical rod for limiting the sliding of the first vertical rod;

[0007] The side wall fixing component includes a cross bar fixedly connected to the second vertical rod and at least two groups of first adjusting members slidable on the cross bar. A number of limiting members are provided on the first adjusting members. When a PCB board is placed, the first adjusting member is slid to clamp the PCB board, and the limiting member is used to limit the sliding of the first adjusting member;

[0008] The hook component includes a hook, a lock for closing the hook, and an elastic element for resetting the lock.

[0009] Furthermore, a second adjusting member is further provided on the lower frame. There are at least two groups of the second adjusting members, and the two groups of the second adjusting members are symmetrically arranged on both sides.

[0010] Furthermore, several limiting members are provided on the top fixing component, and the limiting members are used to limit the sliding of the first vertical rod.

[0011] Furthermore, both the first adjusting member and the second adjusting member are fixing blocks provided with several card slots, the card slots are evenly arranged on the fixing block at equal ratios, and the size of the card slots matches that of the PCB.

[0012] Furthermore, the elastic element is a spring. After the hook is hooked, the spring resets the lock to prevent the hook from unhooking.

[0013] Advantages of the present utility model:

[0014] 1. The side wall fixing component and the top fixing component of the present utility model can slide back and forth on the frame body and are fixed by limiting members, can be slid and adapted according to the sizes of different PCB boards, can match different PCB boards, and improve the scope of use.

[0015] 2. The hook component of the present utility model is provided with a lock. When in use, the present utility model is brought close to the hoisting device, the lock can be pulled inward. After the hoisting rod enters the hook, the elastic element resets the lock to form a closure to prevent unhooking. Description of the drawings
