Embodiment 1

[0035] refer to figure 1 , this embodiment provides a fully automatic etching equipment for the preparation of printed circuit boards. The fully automatic corrosion equipment includes a box body 1 , a grasping mechanism 2 , a stirring mechanism 3 , a liquid replenishing mechanism 4 and a control mechanism 5 .

[0036] Wherein, a gripping mechanism 2 is arranged above the box body 1 for grabbing the circuit board, and placing the circuit board in the corrosive liquid in the box body 1 for corrosion.

[0037] A stirring mechanism 3 is provided on the side wall of the box 1 for stirring the corrosive solution in the box 1 to make the concentration of the corrosive solution in the box 1 uniformly mixed, thereby achieving uniform corrosion of the circuit board.

[0038] The tank 1 is also equipped with a liquid replenishing mechanism 4 for replenishing the corrosive liquid in the tank 1; when the corrosive liquid in the tank 1 is used for a period of time, the concentration of the...

Embodiment 2

[0057] Different from Embodiment 1, the fully automatic corrosion equipment also includes several fixing mechanisms 6 for fixing circuit boards, referring to image 3 , several fixing mechanisms 6 are arranged at the lower part of the grabbing mechanism 2, and the fixing mechanism 6 is grabbed by the grabbing mechanism 2. Setting the fixing mechanism 6 can prevent the grasping mechanism 2 from directly contacting the circuit board, thereby preventing the grasping mechanism 2 from damaging the circuit board.

[0058] Wherein, the fixing mechanism 6 includes an outer frame body 61 and a rubber strip 62 arranged inside the outer frame body 61 , and the rubber strip 62 is provided with a groove for clamping the circuit board. Since the rubber strip 62 is made of soft material, it will not damage the circuit board. Grooves are provided on the rubber strip 62, which can block the circuit board and prevent it from falling during the movement. A layer of anti-corrosion layer is also...

Embodiment 3

[0060] Different from Example 2, refer to Figure 4 The fixing mechanism 6 further includes at least two inner baffles 63 , the inner baffles 63 are arranged inside the outer frame 61 , and the inner baffles 63 and the outer frame 61 are connected by a third electric telescopic rod 64 . The inner side of the inner baffle 63 is provided with a rubber strip 62, and the outer side of the inner baffle 63 is connected with the outer frame body 61 through the third electric telescopic rod 64, and the third electric telescopic rod 64 drives the inner baffle 63 to move to adapt to different sizes. circuit board.

[0061] The number of inner baffles 63 in this embodiment is four, and the number corresponding to the third electric telescopic rod 64 is also four. The movement of the inner baffle 63 is driven by the expansion and contraction of the third electric telescopic rod 64, and then it can be applied Corrosion of circuit boards of different sizes.

Abstract

The invention belongs to the technical field of circuit board processing, and particularly relates to full-automatic corrosion equipment for preparing a printed circuit board. The full-automatic corrosion equipment comprises a box body, a grabbing mechanism, a stirring mechanism, a liquid supplementing mechanism and a control mechanism, wherein corrosion liquid is contained in the box body; the grabbing mechanism is arranged above the box body and used for grabbing a circuit board; the stirring mechanism is arranged on the side wall of the box body and is used for stirring the corrosion liquid in the box body; the liquid supplementing mechanism is arranged on the box body and used for supplementing the corrosion liquid into the box body; and the control mechanism is connected with the grabbing mechanism, the stirring mechanism and the liquid supplementing mechanism and used for controlling operation of the grabbing mechanism, the stirring mechanism and the liquid supplementing mechanism. The full-automatic corrosion equipment has the beneficial effects that manual labor can be reduced, corrosion time is saved, and the effects of good corrosion effect, high working efficiency and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of circuit board processing, in particular to a full-automatic corrosion equipment used for the preparation of printed circuit boards. Background technique [0002] Printed circuit board, also known as printed circuit board, is referred to as PCB (printedcircuitboard or PWB (printedwiringboard) in English. It uses an insulating board as the base material and cuts it to a certain size. At least one conductive pattern is attached to it, and holes (such as component holes , fastening holes, metallized holes, etc.), used to replace the chassis of the previous installation of electronic components, and to realize the interconnection between electronic components. [0003] Most of the etching equipment for circuit boards in the prior art needs to be completed by manpower, that is, by manually shaking the etching box, the etching liquid in the etching box can wash the circuit board, and then corrode the circuit boa...
