Examples
An electrolytic device, as shown in figure 1, comprises an electrolytic tank 3 containing electrolyte, and a spraying device is arranged in the electrolytic tank 3 and used for extracting the electrolyte in the electrolytic tank 3 and spraying the electrolyte on a piece to be etched in the electrolytic tank 3. The piece to be etched is clamped and connected with the anode through the electroplating clamp, and cathodes are fixed on two sides of the anode. Under the action of the electrolyte, cations on the piece to be etched at the anode are decomposed into the electrolyte, flow to the cathode and are attached to the surface layer of the cathode.
As shown in figures 1 and 3, a plurality of spraying units 1 are further arranged in the electrolytic bath 3, each spraying unit 1 comprises a plurality of spraying pipes 11, a plurality of nozzles 12 are linearly arrayed on each spraying pipe 11, and the nozzles 12 vertically point to the direction of the to-be-etched piece. Each nozzle 12 includes a cylindrical nozzle body 121, one end of the nozzle body 121 close to the nozzle pipe 11 is a mounting end, the outer surface of the mounting end is cylindrical, and the nozzle body is screwed in the internal threaded hole of the nozzle pipe 11 in an interference fit manner. The main body of the nozzle 12 deviates from one end of the spray pipe 11 and is an output end, a drainage port 122 is arranged on the side wall of the main body of the nozzle 12, a liquid outlet 123 is arranged at the output end, and the liquid outlet 123 runs through the main body of the nozzle 12 and is communicated with the drainage port 122 and the inner cavity of the spray pipe 11. In order to increase the amount of surging, the drainage opening 122 is formed in the nozzle body 121 by digging a rectangular groove to form at least one pair of straight edges and at least two straight edges.
When electrolyte is sprayed out from nozzle 12, electrolyte around is driven to flow into drainage port 122 through drainage port 122, negative pressure is formed at the corner position of drainage port 122 at the moment, more electrolyte is convenient to drive to enter nozzle 12, the amount of electrolyte sprayed out in unit time in nozzle 12 is more, the amount of surging formed around is larger, and the etching speed is convenient to increase.
The ends of the nozzles 11 of each spraying unit 1 fall on the same vertical line, so that the nozzles 12 in the same spraying unit 1 can be seen as being arranged in several vertical lines. Because the electrolyte pressure sprayed out by the nozzles 12 at different positions on one spray pipe 11 is different, the electrolyte pressure sprayed out by the nozzles 12 on each vertical line can tend to be equal after the arrangement. The plate to be etched moves in the electrolytic bath 3 along the direction of the spray pipe 11, so that the electrolytic etching reaction of the plate to be etched in the vertical direction tends to be uniform, and the whole etching effect of the plate to be etched after the plate to be etched completely passes through the spraying unit 1 also tends to be uniform.
The end of each lance 11 is provided with a switch assembly 13, the switch assembly 13 comprising a flow control unit 131 and an on-off control unit 132, the lance 11 extending into the electrolytic cell 3 in order to facilitate adjustment of the switch assembly 13, the switch assembly 13 being located outside the electrolytic cell 3.

When the electrolyte sprayer is used, the opening and closing degree of the flow control unit 131 is adjusted in advance, and then the on-off control unit 132 is opened, so that electrolyte with a desired pressure flows into the spray pipe 11.
Alternatively, the flow control unit 131 and the on-off control unit 132 can be connected in parallel. The end of the nozzle 11 extending out of the electrolytic bath 3 is divided into two branches, the flow control unit 131 and the on-off control unit 132 are respectively located on the two branches, and the electrolyte in the two branches comes from the same input pipe 2. When the flow control device is required to be used, one of the flow control unit 131 and the on-off control unit 132 is independently opened, wherein two purposes of circulation and flow control can be achieved when the flow control unit 131 is independently opened; the switching on of the on-off control unit 132 alone can only control the on-off of the electrolyte.
As an optimized implementation manner, at least two auxiliary flow control units 133 are connected in series on a branch where the on-off control unit 132 is located, and the auxiliary flow control unit 133 in this embodiment adopts two ball valves, which are respectively located at two ends of the on-off control unit 132.
The end parts of all the spray pipes 11 are connected with input pipes 2, one ends of the input pipes 2 are connected with a pump, and the pump pumps the electrolyte in the electrolytic bath 3 and outputs the electrolyte to each spray pipe 11 communicated with the input pipes 2. The input pipe 2 is vertically arranged and communicated with the end part of the spray pipe 11, the pressure of the electrolyte flowing in the spray pipes 11 with different heights is different, and at the moment, the flow control unit 131 is adjusted to ensure that the flow allowed to pass through the spray pipe 11 at the highest position in unit time is minimum, and the flow allowed to pass through the spray pipe 11 at the lowest position in unit time is maximum, so that the pressure difference of the electrolyte in the spray pipes 11 with different heights is reduced.
As an alternative, each spraying unit 1 is provided with an inlet pipe 2, reducing the pressure difference between each nozzle 11.
As an alternative embodiment, the inlet pipe 2 is arranged horizontally, and the part of the lance 11 extending out of the electrolytic bath 3 is bent and led to the horizontally arranged inlet pipe 2 to communicate with the inlet pipe 2.
As an optimized implementation manner, a pressure gauge or a flow meter is arranged on each nozzle 11 or any nozzle 11 in one spraying unit 1, so as to timely and intuitively represent the flow rate in each nozzle 11, thereby ensuring that the flow rate in each nozzle 11 is basically consistent.
The working process is as follows: adjusting the flow control unit 131, the on-off control unit 132 and the auxiliary flow control unit 133 to a desired degree, and allowing the electrolyte with a desired pressure to flow into the nozzle 11 and be ejected from the nozzle 12; at the moment, the piece to be etched is driven to move at a constant speed in the electrolytic bath 3, electrolytic etching is completed after the plurality of groups of spraying units 1, and the whole etching effect on the whole piece to be etched tends to be equal due to the fact that the etching degree on any vertical position tends to be equal.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description.
