Embodiment

[0023] Such as figure 1 and 2 As shown, a selective cleaning and drying device includes a transmission mechanism, a cleaning mechanism, a water removal mechanism and a drying mechanism, and a transmission mechanism that traverses the above three mechanisms. The cleaning mechanism, the water removal mechanism and the drying mechanism are from Arranged from left to right; the transfer mechanism is used to transfer the circuit board placed on it and pass through the cleaning mechanism, water removal mechanism and drying mechanism in turn; the cleaning mechanism locates the welding area of ​​the wave soldering through the compiled program and performs Selective cleaning.

[0024] After the PCBA board comes out of selective wave soldering, it first enters the cleaning mechanism. The cleaning mechanism includes the first cleaning stage and the second cleaning stage. The length of the first cleaning stage is 900mm, including one solvent cleaning head with servo transmission in x an...

Abstract

The invention relates to a selective washing drying device. The selective washing drying device comprises a washing mechanism, a water removing mechanism, a drying mechanism, and a conveying mechanism which transversely passes through the three mechanisms; the washing mechanism, the water removing mechanism and the drying mechanism are sequentially arranged; the conveying mechanism is used for conveying a circuit board positioned above and sequentially passing through the washing mechanism, the water removing mechanism and the drying mechanism; the washing mechanism is used for positioning a soldering area of wave soldering and selectively washing. Compared with the prior art, the device has the advantages that the washing cycle can be obviously reduced, the liquid medicine for washing can be saved, thus the cost can be saved, and the product quality can be ensured well.

Description

technical field [0001] The invention relates to a cleaning and drying device for circuit boards, in particular to a selective cleaning and drying device. Background technique [0002] Most of the current cleaning machines are offline cleaning, and there is no selective cleaning machine developed for selective wave soldering. Off-line cleaning generally waits for the wave soldering, after the PCBA board is cooled, and then cleans it in the cleaning equipment. On the one hand, the cycle is long. On the other hand, it consumes a lot of energy. This increases the risk of bumping and damaging the PCBA board during product circulation. Even the existing online cleaning machines clean the entire board, and do not perform fixed-point cleaning for specific positions of selective wave soldering. Contents of the invention [0003] The object of the present invention is to provide an easy-to-implement selective cleaning and drying device with a selective cleaning function in order ...
