Description
Technical Field
The invention belongs to the technical field of multilayer printed circuit manufacturing, and particularly relates to an integrated locking hanging basket structure for PCB chemical copper plating production.
Background
The fifth generation mobile communication technology (5th generation mobile networks,5G) is a new communication technology oriented to the future, and compared with the currently widely used fourth generation mobile communication technology (4th generation mobile networks, 4G), the peak rate is increased by tens of times, and the magnitude of the access quantity of the device is also increased. As the requirements of 5G on the carrying capacity of the simultaneous access device and the access speed of a single device are higher, the size of the printed circuit as the core component of the 5G base station is also increasing. Under the same equipment space, due to the increase of the size of the printed circuit board, the number of the devices which can be processed at a time is reduced. Meanwhile, as the penetrability of 5G signal transmission is obviously reduced compared with the previous generation, more 5G base stations need to be arranged to achieve the same coverage effect. Under the traction of dual requirements of 5G communication on the number and the size of PCBs, the production capacity of the printed circuit industry must be improved, and the improvement of the production efficiency is the fastest, most economical and most effective way for improving the production capacity.
Electroless copper plating is the most central and time-consuming process in PCB production. The electroless copper plating is an important step in actual production, and a conductive copper seed layer can be attached to the hole of the printed circuit board by utilizing the electroless copper plating, so that basic conditions are provided for subsequent electroplating processing. At present, a more general copper plating loading method in the industry is to load printed circuit boards with different sizes by using sub hanging baskets with smaller sizes, and integrate a plurality of sub hanging baskets into an integral hanging unit through a larger-size mother hanging basket. Because the printed circuit board size that needs processing is different, and in addition there is mechanical measure who swings, vibrate etc. and get rid of downthehole bubble in the course of working, the son hangs still needs a fixing device between basket and the mother hangs the basket, and the device needs can prevent in the course of working that the son hangs the basket and drops from mother hangs the basket. From the analysis of actual production test data, the fixture needs to provide at least two directional support for a single small hanging basket at a minimum, as there is still a risk of falling if there is only one directional support. According to the patent CN201921306777.5, "a PCB heavy copper hanging basket" extends the outside middle position steel bar of the large-size hanging basket frame upwards, plays the role of fixing the bottom of the sub-hanging basket, but the design neglects the fixation of two sides, the problem that the sub-hanging basket is separated from the main hanging basket easily occurs in the process of single-side support, and extra fixing measures are actually still needed to reinforce the side surface of the sub-basket. And if additional fixing measures are manually carried out, the production efficiency is influenced to a certain extent.
Patent CN201710367375.5 "heavy copper hanging basket and conveyor including heavy copper hanging basket" has introduced the notion of clamping layer in hanging the basket, can be with firm the fixing in hanging the basket of printed circuit board through upper and lower clamping layer, but this design is when facing many batches of different size printed circuit boards, and the problem that can't fix small-size printed circuit board in partial clamping layer can be difficult to avoid to appear. Meanwhile, the printed circuit board to be processed can be clamped and fixed only after being completely loaded, and certain falling risk exists when a large-size printed circuit board is loaded. Patent CN201920937936.5 "a heavy copper frame of gravity PCB" provides a method for locking by the self gravity of the printed circuit board, which skillfully utilizes the self weight of the printed circuit board through a mechanical structure, and realizes the function that the female cradle automatically unlocks when no load is present, and automatically locks after the printed circuit board to be processed is loaded. However, the whole structure of the method is of a locking design and is complex. Meanwhile, the normal starting of the device requires the self weight of the loaded printed circuit board to reach a certain level, and the device is lack of flexibility when facing the processing of a large number of small-batch products. Patent CN201620501371.2 "a width adjustable suspension tool that is used for the heavy copper of different PCBs", patent CN201820595059.3 "heavy copper assembly line titanium basket", patent CN201620413293.0 "PTH picture peg device", patent CN200920204672.9 "heavy copper transfer machine improvement type model picture peg frame" all used the comb strip to fix printed circuit board at the bottom and the side of hanging the basket. The structure fixes the printed circuit board in the tooth groove, and can effectively prevent the phenomenon that the printed circuit falls off due to shaking in the processing process. But this kind of structure needs frequent upper and lower fixed screw in the printed circuit board loading and unloading process before processing, and because there is not primary and secondary basket design, the time of spending is more, and production efficiency is lower relatively, and only can manual field operation, can't carry out automation or unmanned upgrading transformation.
Therefore, how to realize that the primary and secondary hanging baskets can be well fixed and have faster upper and lower plate production capacity and simple and automatic compatible operation modes when the primary and secondary hanging baskets are adopted in the electroless copper plating production becomes a problem to be solved urgently.
