Description

Technical Field

[0001] This utility model relates to the field of gravure electroplating technology, specifically an automatic liquid return mechanism for gravure electroplating. Background Technology

[0002] Gravure electroplating refers to the process of depositing a layer of metal or alloy on a metal surface. By adding the corresponding metal salt to the electrolyte, metal ions are reduced and deposited on the metal surface to form the desired coating. In the process of gravure plate making, electroplating is mainly used to make copper plates for the graphic parts. In the process of gravure electroplating, an automatic liquid return mechanism is required to collect the plating solution.

[0003] For example, the automatic liquid return mechanism for gravure electroplating equipment disclosed in Chinese Patent Publication No. CN107675224B includes a lifting rod, a guide cylinder, a guide sleeve, a lifting rod seat, a sealing valve core, a cylinder, a cylinder connector, a push rod, a connecting rod seat, and a connecting rod, etc.; by controlling the extension and retraction of the cylinder through a solenoid valve, it is possible to determine whether the plating solution in the plating bath flows back to the storage tank; the use of this mechanism can reduce manual operations by operators, improve production efficiency, and reduce occupational hazards caused by inhalation of volatile substances during the visual observation of the plating solution in the original mechanism.

[0004] However, in order to achieve the automatic liquid return function, the above-mentioned automatic liquid return mechanism requires the extension and retraction of the cylinder to make the sealing valve core and the sealing seat fit or separate. This not only increases the cost of use, but also affects the performance of the automatic liquid return mechanism. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic liquid return mechanism for gravure electroplating to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic liquid return mechanism for gravure electroplating, comprising an automatic liquid return cylinder and a self-returning component for collecting gravure electroplating solution; the self-returning component is arranged inside the automatic liquid return cylinder; the self-returning component includes a fixed plate, a sliding rod, a sliding plate, a spring A, and a leakage groove; the fixed plate is fixedly mounted inside the automatic liquid return cylinder by a plurality of fixed rods arranged in a circular array; the sliding rod slides through the fixed plate; the sliding plate slides inside the automatic liquid return cylinder, and the sliding plate is fixedly connected to the end of the sliding rod; the spring A is sleeved on the sliding rod, and both ends of the spring A are fixedly connected to the fixed plate and the sliding plate respectively; a leakage groove is formed on the inner surface of the automatic liquid return cylinder.

[0007] Preferably, the sliding plate has an arc-shaped structure, and the sliding plate is fixed inside the automatic return cylinder by an elastic fixing component.

[0008] Preferably, the leakage channel has a superior arc structure, and the cross-section of the leakage channel is an isosceles trapezoidal structure with a larger inner diameter and a smaller outer diameter.

[0009] Preferably, the elastic fixing component includes a fixed base, a movable groove, a movable block, a spring B, a positioning groove, and a positioning block; the fixed base is fixedly disposed on the outer surface of the automatic return cylinder; the fixed base has a movable groove inside; the movable block slides through the movable groove and extends into the automatic return cylinder; both ends of the spring B are fixedly connected to the inner wall of the movable groove and the movable block, respectively; the movable block has a positioning groove; the positioning block is fixedly disposed on the sliding plate and is inserted into the positioning groove.

[0010] Preferably, the movable block has a right-angled trapezoidal structure, and the inclined surface of the movable block is arranged upward and in contact with the inner wall of the movable groove.

[0011] Preferably, the elastic strength of spring B is less than that of spring A.

[0012] Preferably, the positioning block is an isosceles triangular structure, the inclined surface of the positioning block is arranged in the vertical direction, and the tip of the positioning block is in contact with the end face of the movable block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting a self-returning component, fixes the storage tank to the automatic return cylinder via a threaded connection. Then, the plating solution in the automatic return cylinder will slide downwards within the cylinder under its own weight, causing the sliding plate to slide downwards on the fixed plate, and spring A to contract under force until the sliding plate slides into the leakage trough. At this time, the plating solution will flow into the storage tank through the gap between the sliding plate and the leakage trough. As the amount of plating solution decreases, spring A will gradually extend, causing the sliding plate to slide upwards within the automatic return cylinder, and the sliding rod to slide upwards on the fixed plate, until spring A returns to its original shape. Compared with the prior art, this utility model has a simple and reasonable structure and ingenious design. It can achieve automatic return of plating solution through its own weight, greatly reducing the cost of use and making it highly practical.

[0015] 2. By setting up an elastic fixing component, when the sliding plate slides downward in the automatic return liquid cylinder, the inclined surface of the positioning block will press against the inner wall of the positioning groove, causing the movable block to slide in the movable groove. This causes the spring B to contract under force. Not only can the plating solution in the automatic return liquid cylinder be guided to the sliding plate through the inclined surface of the movable block, so that the force of the plating solution falls on the sliding plate to the maximum extent, so that the sliding plate can slide downward, but the position of the sliding plate can also be fixed by the insertion of the positioning block and the positioning groove.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figures 1-4As shown, this utility model provides a technical solution for an automatic liquid return mechanism for gravure electroplating, including an automatic liquid return cylinder 1 for collecting gravure electroplating solution, a self-returning component 2, and an elastic fixing component 3; the self-returning component 2 is arranged inside the automatic liquid return cylinder 1; the self-returning component 2 includes a fixed plate 201, a sliding rod 202, a sliding plate 203, a spring A204, and a leakage groove 205; the fixed plate 201 is fixed inside the automatic liquid return cylinder 1 by a plurality of fixed rods arranged in a circular array; the sliding rod 202 slides through the fixed plate 201; the sliding plate 203 slides inside the automatic liquid return cylinder 1, and the sliding plate 203 is in contact with the sliding rod 204. The end of the moving rod 202 is fixedly connected; the spring A204 is sleeved on the sliding rod 202, and the two ends of the spring A204 are fixedly connected to the fixed plate 201 and the sliding plate 203 respectively; a leakage groove 205 is opened on the inner surface of the automatic liquid return cylinder 1; in order to prevent the sliding plate 203 from sliding down excessively, a baffle can be set at the bottom wall of the leakage groove 205, and the baffle does not affect the flow of the plating solution; the sliding plate 203 has an arc structure, and the sliding plate 203 is fixed in the automatic liquid return cylinder 1 by the elastic fixing component 3; the leakage groove 205 has an arc structure, and the cross-section of the leakage groove 205 is an isosceles trapezoidal structure with a larger inner diameter and a smaller outer diameter.

[0026] This invention, by setting a self-returning component 2, fixes the storage tank to the automatic return cylinder 1 via a threaded connection. Then, the plating solution in the automatic return cylinder 1 will slide downward within the cylinder under its own weight, causing the sliding plate 203 to slide downward on the fixed plate 201, and the spring A204 to contract under force until the sliding plate 203 slides into the leakage trough 205. At this time, the plating solution will flow into the storage tank through the gap between the sliding plate 203 and the leakage trough 205. As the amount of plating solution decreases, the spring A204 will gradually extend, causing the sliding plate 203 to slide upward within the automatic return cylinder 1, and the sliding rod 202 to slide upward on the fixed plate 201, until the spring A204 returns to its original shape. Compared with the prior art, this invention has a simple and reasonable structure and ingenious design. It can achieve automatic return of plating solution through its own weight, greatly reducing the cost of use and making it highly practical.

[0027] In a preferred embodiment, the elastic fixing component 3 includes a fixed base 301, a movable groove 302, a movable block 303, a spring B304, a positioning groove 305, and a positioning block 306; the fixed base 301 is fixedly mounted on the outer surface of the automatic return cylinder 1; the movable groove 302 is provided inside the fixed base 301; the movable block 303 slides through the movable groove 302 and extends into the automatic return cylinder 1; both ends of the spring B304 are fixedly connected to the inner wall of the movable groove 302 and the movable block 303, respectively; the movable block 303 is provided with a positioning groove 305; the positioning block 306 is fixedly mounted on the sliding plate 203 and is connected to the fixed base 301. The slot 305 is inserted into the groove; the movable block 303 is a right-angled trapezoidal structure, and the inclined surface of the movable block 303 is set upward and contacts the inner wall of the movable groove 302; the elastic strength of spring B304 is less than that of spring A204, so that the sliding plate 203 can slide to its original position through the elastic force of spring A204; the positioning block 306 is an isosceles triangular structure, and the inclined surface of the positioning block 306 is set vertically, and the tip of the positioning block 306 contacts the end face of the movable block 303; when the sliding plate 203 slides into the leakage groove 205, the tip of the positioning block 306 contacts the end face of the movable block 303.

[0028] This utility model, by setting up an elastic fixing component 3, causes the sliding plate 203 to slide downward in the automatic return liquid cylinder 1, which in turn causes the inclined surface of the positioning block 306 to press against the inner wall of the positioning groove 305, causing the movable block 303 to slide in the movable groove 302, and causing the spring B304 to contract under force. This not only guides the plating solution in the automatic return liquid cylinder 1 to the sliding plate 203 through the inclined surface of the movable block 303, so that the force of the plating solution falls on the sliding plate 203 to the maximum extent, so that the sliding plate 203 slides downward, but also fixes the position of the sliding plate 203 by inserting the positioning block 306 into the positioning groove 305.

[0029] Working principle: In use, the storage tank is fixed to the automatic return tank 1 by a threaded connection. Then, the plating solution in the automatic return tank 1 will slide downwards within the tank under its own weight, causing the sliding plate 203 to slide downwards on the fixed plate 201. This causes the spring A204 to contract, which in turn causes the inclined surface of the positioning block 306 to press against the inner wall of the positioning groove 305. This causes the movable block 303 to slide within the movable groove 302, causing the spring B304 to contract until the sliding plate 203 slides into the leakage tank 2. At point 05, the plating solution flows into the storage tank through the gap between the sliding plate 203 and the leakage tank 205. As the amount of plating solution decreases, the spring A204 gradually extends, causing the sliding plate 203 to slide upward in the automatic return cylinder 1, and causing the sliding rod 202 to slide upward on the fixed plate 201 until the end of the positioning block 306 contacts the inner wall of the positioning groove 305. At this time, under the elastic force of the spring B304, the positioning block 306 will be inserted into the positioning groove 305, and the springs A204 and B304 will return to their original shapes.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
