Description

A kind of PCB glass etching machine

Technical field

The utility model relates to a kind of glass etching machine, relates in particular to a kind of PCB glass etching machine.

Background technology

At present, when making PCB, need to carry out the glass etch processes to the upper all holes of PCB, particularly, in the process of just eat-backing the processing procedure exploitation and using, after the Plasma processing through the front, resin in the hole is snapped eating away, form in the hole and just eat-back, and glass Shu Wei stings erosion and protrudes hole wall, therefore need to dispose to the glass that the special etching solution of spray in the hole will protrude hole wall, and present stage all is the spray of realizing liquid medicine by the manual mode of people, yet adopting manually, spray liquid medicine has following problem:

1, manual production efficiency is low;

2, be difficult to control the pressure of liquid medicine ejection, the pressure that the liquid medicine ejection often occurs is excessive, and the glass bundle in the hole is scattered by excess impact, the phenomenon that causes the electro-coppering knurl to produce;

3, be difficult to accurately grasp the spray time of liquid medicine, thereby can not accomplish appropriate etching, the quality of product can not be guaranteed.

The utility model content

For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of PCB glass etching machine, to realize automatic production, enhances productivity, and avoids producing the electro-coppering knurl, guarantees the quality of product.

The utility model adopts following technical scheme for achieving the above object:

A kind of PCB glass etching machine, comprise frame, be installed on power wheel, liquid medicine container, pump, jet pipe on the frame, described erecting is equipped with work nest and lower work nest, described power wheel is between upper work nest and lower work nest, it comprises two groups up and down, is driven by driving motor, for delivery of PCB; The entrance of described pump is connected with the outlet of liquid medicine container, and pump outlet is connected with the entrance of jet pipe, and this pump also is provided with a frequency-variable controller for automatic adjustable jet tube pressure; Described jet pipe is provided with a plurality of nozzles, and those nozzles are interspersed up and down, and the nozzle of top is positioned at the top of power wheel, and the nozzle of below is positioned at the below of power wheel.

Wherein, for the flow of adjustable jet tube, described jet pipe is provided with variable valve.

Wherein, the below of described power wheel also is provided with a ultrasonic generator, strengthens cleaning to the PCB hole wall by ultrasonic wave.

A kind of PCB glass etching machine that the utility model is set forth, its beneficial effect is: the utility model is controlled the treatment time automatically by frequency-variable controller, adjustable jet tube pressure, not only realized automatic production, improved production efficiency, and can prevent the glass Shu Zaocheng excess impact in the hole, avoid producing the electro-coppering knurl, moreover, can also accomplish appropriate etching, guarantee the quality of product.

Embodiment

Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.

Please refer to illustrated in figures 1 and 2, it has demonstrated the concrete structure of the utility model preferred embodiment, a kind of PCB glass etching machine, comprise frame 10, be installed on power wheel 20, liquid medicine container (not shown), pump 30, jet pipe 40 on the frame 10, described frame 10 is provided with work nest 11 and lower work nest 12, described power wheel 20 is between upper work nest 11 and lower work nest 12, it comprises two groups up and down, is driven by driving motor, for delivery of PCB; The entrance of described pump 30 is connected with the outlet of liquid medicine container, and the outlet of pump 30 is connected with the entrance of jet pipe 40, and this pump 30 also is provided with a frequency-variable controller 31 for automatic adjustable jet tube 40 pressure; Described jet pipe 40 is provided with a plurality of nozzles 41, and those nozzles 41 are interspersed up and down, and the nozzle 41 of top is positioned at the top of power wheel 20, and the nozzle 41 of below is positioned at the below of power wheel 20.

Wherein, for the flow of adjustable jet tube 40, described jet pipe 40 is provided with variable valve.

Wherein, the below of described power wheel 20 also is provided with a ultrasonic generator 50, strengthens cleaning to the PCB hole wall by ultrasonic wave.

During use, pending PCB is placed on the power wheel 20 carries, in course of conveying, pump 30 extracts the liquid medicine in the liquid medicine container to jet pipe 40, the nozzle 41 of jet pipe 40 spray liquid medicine in the hole on from both direction up and down towards PCB, the glass bundle of hole wall is protruded in etching, simultaneously, the liquid medicine of jet pipe 40 ejection accumulates in the work nest 11 and PCB is flooded immersion, i.e. etching section has adopted the mode that adds spray of soaking.Liquid medicine collects the lower work nest 12 of the both sides flow direction by upper work nest 11 after upper work nest 11 overflows, so that process and recycling, on the other hand, ultrasonic generator 50 also can send the ultrasonic wave reinforcement to the cleaning of PCB hole wall, the more important thing is, when jet pipe 40 spray, frequency-variable controller 31 will be controlled the spray time of liquid medicine automatically, and automatic adjustable jet tube 40 pressure, prevent the glass Shu Zaocheng excess impact in the hole, thereby realized automatic production, improved production efficiency, avoid producing the electro-coppering knurl, accomplish appropriate etching, guaranteed the quality of product.
