Description

Technical Field

[0001] This invention relates to the field of PCB pickling, and particularly to a PCB pickling equipment. Background Technology

[0002] PCB refers to Printed Circuit Board, which is mainly used for the electrical connection of various electronic components. It is an important carrier in the electronics industry. With the continuous development of related technologies, the integration level of PCBs is getting higher and higher, making electronic products more and more precise. PCBs need to undergo acid pickling during production and processing. Therefore, in order to improve the convenience of PCB acid pickling, PCB acid pickling equipment is needed to process PCBs.

[0003] For example, the PCB pickling equipment with patent number CN219802682U fixes the PCB board by placing it in two sets of positioning frames and locking it with a limiting mechanism. At this time, the PCB board is suspended below the two sets of positioning frames. During the subsequent pickling process, when the positioning frames and other components move, and when the PCB board is disturbed by the fluctuation of the liquid, the PCB board is prone to slipping off the positioning frames due to the interference of the above factors. This is not conducive to improving the stability and safety of the PCB board pickling. At the same time, when people are handling PCB boards on one side of the pickling tank, the liquid level in the pickling tank is often high, which may cause people to come into contact with it, thus making it easy for safety accidents to occur. Summary of the Invention

[0004] The purpose of this invention is to provide a PCB board pickling equipment.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A PCB pickling device includes a housing I with an agitation mechanism at the bottom, a housing II communicating with the bottom side of housing I, a push plate inside housing II, a lead screw driven by motor I screwed onto the push plate, a vertical plate fixing the end of the lead screw to the opening of housing II via a bearing, a cover plate for sealing the opening of housing I, the cover plate being driven by a hydraulic rod, fixing mechanisms extending into housing I on both sides of the bottom of the cover plate, the fixing mechanisms including two sets of fixing plates and a base plate connecting the bottom ends of the two sets of fixing plates, a C-shaped seat with an upward opening evenly distributed on the top of the base plate, and a pressure plate located between the two sets of fixing mechanisms at the bottom of the cover plate, the pressure plate being driven by an electric push rod.

[0007] Preferably, the agitation mechanism includes a motor II disposed on the outside of the housing I, and a rotating shaft located inside the housing I is disposed on the output shaft of the motor II. The end of the rotating shaft is fixed to the vertical plate by a bearing, and an agitator is disposed on the rotating shaft.

[0008] Preferably, the size of the push plate is adapted to the size of the internal opening of the housing II, the push plate is provided with a screw hole for screwing with the lead screw, and the housing II is provided with a slide rod that passes through the slide hole on the push plate. The two ends of the slide rod are respectively fixedly connected to the corresponding side wall and vertical plate of the housing II.

[0009] Preferably, a return pipe connected to the side wall of box I is provided on the top of box II, which is located away from box I, and a check valve is provided on the return pipe near box I.

[0010] Preferably, the top two sides of the cover plate are provided with extension plates extending to the outside of the box body I, and the output shaft of the hydraulic rod is fixedly connected to the bottom of the extension plate.

[0016] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] A PCB pickling device includes a housing I1 with an agitation mechanism 2 at the bottom. The agitation mechanism 2 includes a motor II21 disposed on the outside of the housing I1. A rotating shaft 22 located inside the housing I1 is disposed on the output shaft of the motor II21. An agitator 23 is disposed on the rotating shaft 22.

[0018] Box I1 has a box II3 connected to it on one side of its bottom. A push plate 4 is installed inside box II3. A lead screw 5 driven by motor I6 is screwed onto the push plate 4. A vertical plate 7 is installed at the opening of box II3, which fixes the end of the lead screw 5 by bearing. The end of the rotating shaft 22 is fixed to the vertical plate 7 by bearing. The size of the push plate 4 is adapted to the size of the opening inside box II3. The push plate 4 has a screw hole for screwing onto the lead screw 5. A slide rod 13 is installed inside box II3, which passes through the slide hole on the push plate 4. The two ends of the slide rod 13 are fixedly connected to the corresponding side wall of box II3 and the vertical plate 7, respectively.

[0019] The top opening of the housing I1 is also provided with a cover plate 8 that can seal it. The cover plate 8 is driven by a hydraulic rod 9. The bottom sides of the cover plate 8 are provided with fixing mechanisms 10 that can extend into the housing I1. The fixing mechanism 10 includes two sets of fixing plates 101 and a bottom plate 102 connecting the bottom ends of the two sets of fixing plates 101. The top of the bottom plate 102 is evenly provided with C-shaped seats 103 with the opening facing upward. The bottom of the cover plate 8 is also provided with a pressure plate 11 located between the two sets of fixing mechanisms 10. The pressure plate 11 is driven by an electric push rod 12.

[0020] like Figure 1 , 2 As shown, a return pipe 14 connected to the side wall of box I1 is provided on the top of box II3, which is far away from box I1, and a check valve 15 is provided on the return pipe 14 near box I1.

[0021] like Figure 1 , 2 As shown, the top two sides of the cover plate 8 are provided with extension plates 16 extending to the outside of the box body I1, and the output shaft of the hydraulic rod 9 is fixedly connected to the bottom of the extension plate 16.

[0022] In this embodiment, the pressure plate 11 and the base plate 102 are arranged in parallel, and the lengths of the pressure plate 11 and the base plate 102 are equal. The top of the pressure plate 11 is also provided with a limiting rod 17 and a connecting rod 18 that penetrate the through hole on the cover plate 8. The output shaft of the electric push rod 12 is fixedly connected to the top of the connecting rod 18. The top of the cover plate 8 is provided with a bracket 19 for fixing the electric push rod 12.

[0023] The method of using this invention is as follows: When a series of operations such as picking up and putting down materials are performed on the outside of the box I1, the motor I6 drives the lead screw 5 to rotate in the screw hole on the push plate 4, thereby driving the push plate 4 to move to the left. At this time, the sliding hole on the push plate 4 slides on the slide rod 13. When the push plate 4 moves to the left, the liquid in the box I1 flows into the box II2 on the right side of the push plate 4, thereby lowering the liquid level in the box I1 and preventing people located outside the box I1 from easily coming into contact with the liquid level in the box I1 and being injured.

[0024] The PCB board is fixed in an orderly manner on two sets of fixing mechanisms 10. Specifically, the two ends of the PCB board are placed in the openings of the corresponding C-shaped seats 103 in the two sets of fixing mechanisms 10. The two sets of C-shaped seats 103 support and fix the two ends of the PCB board to prevent it from swinging. At the same time, the two ends of the PCB board extend to the outside of the fixing mechanism 10 and are suspended in the air so that it can support and fix PCB boards of different lengths. Then, the electric push rod 12 drives the connecting rod 18 to move down in the through hole, while driving the pressure plate 11 to move down. The pressure plate 11 after moving down contacts the top of the front and rear sets of PCB boards, thereby locking and fixing them on the C-shaped seats 103 to prevent the PCB board from slipping off the fixing mechanism 10 without human intervention.

[0025] Next, the hydraulic rod 9 drives the fixing mechanism 10 and the PCB board to slide into the top of the box I1 through the extension plate 16. At this time, the motor I6 reverses and drives the push plate 4 to rotate through the lead screw 5 while moving it to the right. This causes the push plate 4 to push out the liquid in the box II3 and return it to the box I1, thereby raising the liquid in the box I1 so that it overflows the PCB board for processing. During this process, the stirring mechanism 2 stirs the liquid in the box I1 to accelerate the processing efficiency of the product. In this embodiment, the push plate 4 and the box II3 are interference-fitted so that the liquid in the box II3 on ​​the right side of the push plate 4 will not flow into the left side. If a small amount of liquid may flow into the left side, when the push plate 4 moves to the left, it can squeeze the liquid into the return pipe 14 and into the box I1. The check valve 15 prevents the liquid in the box I1 from flowing back into the box II3 through the return pipe 14. At the same time, a small amount of liquid on the left side of the box II3 can also be discharged through the water outlet pipe at the bottom of the left side and recycled.

[0026] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
