Description

Technical Field

[0001] The invention belongs to the technical field of spray etching equipment, and in particular relates to a spray filtering device and an etching system. Background Art

[0002] Etching is a technology that uses chemical reactions or physical impact to remove materials. Etching is usually referred to as photochemical etching, which refers to the removal of the protective film of the area to be etched after exposure and development. During etching, the area is exposed to chemical solutions to dissolve and corrode, forming a concave-convex or hollow-out effect. The automatic chemical etching machines seen on the market today use high-pressure spraying and linear motion of the etched plate to form a continuous and uninterrupted feeding state to corrode the workpiece to improve production efficiency, increase the effective area of ​​the spray and the etched metal plate, and the uniformity of etching. Whether in terms of etching effect, speed, and improving the operator's environment and convenience, they are superior to traditional splash etching.

[0003] Since the chemical solution needs to be sprayed continuously, the etching machine often needs to recycle the chemical solution for circulating spraying. When the etching solution etches the original plate, powder, solid impurities and copper salt precipitation etched from the original plate will remain in the chemical solution. When the etching solution is recovered after use, if the solid impurities are not removed, these powders will accumulate on the nozzle as the chemical solution circulates, or accumulate in the pipeline or nozzle for a long time, causing blockage. To solve this problem, the current filter structure is generally fixed in the etching system, which makes it difficult to disassemble and clean the filter structure later. In addition, most flat-plate filters only recover the etching solution by gravity, and the chemical solution pressure is low and the filtration speed is slow, resulting in low overall processing efficiency.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] Reference Figure 1 - Figure 8 The spray filtering device of the present invention comprises an etching machine body 1 and a collecting barrel 12 fixedly mounted on the bottom of the inner wall of the etching machine body 1, a supporting plate 22 is symmetrically clamped on the top of the inner wall of the collecting barrel 12, and the tops of the two supporting plates 22 are fixedly connected with supporting rods 21, and one end of the two supporting rods 21 is jointly mounted with a diversion mechanism;

[0031] A conical filter bucket 13 is fixedly connected to the side wall of the collection bucket 12, a step support ring 14 is fixedly connected to the bottom side wall of the conical filter bucket 13, a filter cage 15 is abutted on the upper surface of the step support ring 14, a filter net bag 16 is fixedly connected to the top of the filter cage 15, and one end of the filter net bag 16 is attached to the surface of the filter cage 15 and extends to the bottom of the step support ring 14;

[0032] Specifically, if Figure 4 and Figure 5As shown, the diversion mechanism includes a mounting block 20 fixedly connected to the opposite side of two support rods 21, and the lower surface of the mounting block 20 is rotatably connected to a fan blade 19, the surface of the fan blade 19 is in an inward buckled state, and the lower surface of the fan blade 19 is fixedly connected to a mounting plate 18, and the lower surface of the mounting plate 18 is fixedly connected to an upper convex inclined plate 17, and the upper convex inclined plate 17 is a circular structure that convexes upward. When the etching liquid falls downward on the surface of the fan blade, due to the special curved surface structure of the fan blade 19, no matter where it drips on the fan blade 19, it will push the fan blade 19 to rotate in the inward buckled direction, thereby driving the lower mounting plate 18 to rotate (the center of the mounting plate 18 is also slightly convex upward), and then driving the upper convex inclined plate 17 to rotate, so that the etching liquid can flow along the inclined surface of the upper convex inclined plate 17 and be evenly swung around, so that it falls downward to the top edge of the conical filter bucket 13 in the form of an annular water curtain to perform a filtering operation.

[0033] The inclined conical filter hopper 13 can filter impurities from the fallen etching liquid. The filtered impurities will fall into the central filter cage 15 and be collected under the action of the inclined gravity and the impact of the etching liquid flow.

[0034] The filter cage 15 includes a mounting ring 1501 and a side tube 1502. The mounting ring 1501 is fixedly connected to the top of the side tube 1502, and the lower surface of the mounting ring 1501 is in contact with the inner side of the step support ring 14. The bottom of the side tube 1502 passes through and extends to the bottom of the step support ring 14, that is, the filter cage 15 is directly placed on the inner side of the step support ring 14 through a snap-on manner between the mounting ring 1501 and the step support ring 14, and the filter cage 15 can be disassembled by directly lifting it upwards and taking it out, which makes disassembly and assembly more convenient.

[0035] The filter net bag 16 includes a net bag body 1601, an elastic extension edge 1602 and two drawstrings 1603. The net bag body 1601 is placed inside the filter cage 15. The elastic extension edge 1602 is fixedly connected to the top outer edge of the net bag body 1601, and the elastic extension edge 1602 abuts between the step support ring 14 and the opposite side of the filter cage 15. The two drawstrings 1603 are fixedly connected to the two ends of the elastic extension edge 1602 respectively.

[0036] The filtered impurities will actually be collected inside the net bag body 1601, and the elastic extended edge 1602 of the filter net bag 16 is supported by the step support ring 14 and the filter cage 15, and will not easily fall off the filter cage 15, thereby ensuring the overall stability. Furthermore, the two pull ropes 1603 can be tightened and knotted around the outer surface of the filter cage 15, which can further enhance the reliability of the connection between the net bag body 1601 and the filter cage 15 and prevent it from falling off.

[0037] At the same time, the filter net bag 16 is sleeved on the filter cage 15, and the filter cage 15 can be cleaned by replacing the filter net bag 16, which is easier to operate. The convenience of the entire replacement operation can be achieved by making a disposable filter net bag 16.

[0038] like Figure 2 and Figure 3 As shown, the bottom of one side of the outer surface of the collecting barrel 12 is fixedly connected with a conduit 11, one end of the conduit 11 is fixedly connected with a pump body 10, and the liquid inlet of the pump body 10 is fixedly connected with the conduit 11, and the liquid outlet of the pump body 10 is fixedly connected with a liquid infusion tube 25, one end of the liquid infusion tube 25 is fixedly connected with a spray plate 23, the interior of the spray plate 23 is hollow, so that it can be used as a transfer station for etching liquid, and a plurality of nozzles 24 are fixedly installed on the lower surface of the spray plate 23, and the array of nozzles 24 is evenly distributed on the lower surface of the spray plate 23;

[0039] The pump body 10 can collect the filtered etching liquid in the collection barrel 12 through the conduit 11, and lift it upward to the inside of the spray plate 23 through the infusion pipe 25, and finally spray it downward through the nozzle 24 to etch the workpiece.

[0040] Example 2

[0041] An etching system includes the above-mentioned spray filtering device, wherein the lower surface of the etching machine body 1 is fixedly connected with support seats 7 on all sides, the front of the etching machine body 1 is symmetrically hinged with door panels 5, and the fronts of the two door panels 5 are fixedly connected with handles 6. The two door panels 5 can be opened by the handles 6, which is convenient for the staff to carry and disassemble the diversion mechanism.

[0042] The top of the etching machine body 1 is fixedly connected to the chassis shell 2, wherein both ends of the infusion tube 25 pass through the etching machine body 1 and the chassis shell 2 respectively (the end of the infusion tube 25 inside the etching machine body 1 has a connecting section extending to one side of the collecting barrel 12, thereby ensuring that it is just below the spray plate 23 when it extends to the outside of the etching machine body 1), and the concave bend of the infusion tube 25 is fixedly connected to a diagonal brace 26. The presence of the diagonal brace 26 can enhance the lateral stability of the infusion tube 25, thereby ensuring the reliability of the infusion tube when transporting the etching liquid.

[0043] A control box 4 is fixedly installed at one end of the front of the chassis shell plate 2, wherein the pump body 10 is electrically connected to the control box 4, and the pump body 10 can be controlled through the control box 4, and a glass panel 3 is fixedly connected to the other end of the front of the chassis shell plate 2 and corresponds to the position of the spray plate 23, and the staff can observe the etching operation of the etching liquid on the workpiece through the glass panel 3;

[0044] The side wall of the chassis shell plate 2 is symmetrically provided with slots 8, and a conveying mechanism 9 is fixedly installed inside the chassis shell plate 2 and corresponding to the position of the slot 8. The conveying mechanism 9 can use a conveyor belt (with filter holes) commonly used in the prior art or a number of parallel conveying rollers to convey the workpiece: the workpiece is conveyed from one end of the conveying mechanism 9, passes through the slot 8 into the interior of the chassis shell plate 2, and after etching, passes through the slot 8 at the other end to continue the subsequent processing process.

[0045] The working principle of the spray filtering device and the etching system of the present invention is specifically as follows: when etching a workpiece, it is necessary to use an etching liquid to spray it. First, the workpiece is placed on the plate placing and conveying mechanism 9 for conveying. When it is conveyed to the bottom of the spray plate 23, the etching liquid conveyed through the conveying pipe 25 will be sprayed through the nozzle 24 to spray the workpiece below. During the spraying process, the used etching liquid will fall downward. When the etching liquid falls downward into the collection barrel 12, it will first drip on the surface of the fan blade 19, thereby driving the fan blade 19 to rotate, so that the etching liquid is dispersed into a circular water curtain through the upper convex inclined plate 17, and then falls to the top edge of the conical filter bucket 13 for filtration. The utilization of the conical filter bucket While the filtering rate is higher, the overall filtering effect is better. At the same time, on the inclined filtering surface, the liquid can pass through the mesh faster and more smoothly during filtering, and the filter cage 15 and the filter net bag 16 can separate the etching liquid from the solid impurities and waste residues in the etching liquid. The solid impurities are collected in the interior of the filter net bag 16, and the filtered etching liquid flows into the bottom of the collection barrel 12 for recycling, avoiding the problem of solid impurities and waste residues clogging the spray pipe, thereby improving production efficiency. In addition, the filter cage 15 and the filter net bag 16 can be easily separated from the step support ring 14 (by opening the door panel 5, lifting the support plate 22 and the support rod 21 upward, thereby taking out the diversion mechanism, and further disassembling the filter cage 15), thereby realizing disassembly and replacement, and the operation is more convenient.

[0046] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the present invention and various different selections and changes.
