DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] In order to better understand the above technical solution, the exemplary embodiments of the present invention will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present invention are illustrated in the drawings, it should be understood that the present invention can be realized in various ways and should not be construed as being limited to the embodiments described herein. Rather, these embodiments are provided to make the present invention more clear and thorough and to fully convey the scope of the present invention to those skilled in the art.

[0018] As shown in FIGS. 1 to 3, a specific embodiment of the present invention provides an electroplating tank having a function of guiding a plating solution by a side wall, and includes a bottom plate 1, a first side wall 2 and a second side wall 3 disposed on the bottom plate 1 so as to face each other. The first side wall 2 is provided with a first guide area 21 including a first side plate 211 having a first overflow hole 212 formed therein. The second side wall 3 is provided with a second guide area 31 including a second side plate 311 having a second overflow hole 312 formed therein. The second side wall 3 is further provided with a plurality of drain holes 32 which are connected to the second guide area 31 and have a height lower than that of the first overflow hole 212 and the second overflow hole 312. The bottom plate 1 is provided with a third guide area 11 which is connected to the first guide area 21 and the second guide area 31, respectively, to guide the plating solution in the first guide area 21 to the second guide area 31.

[0019] Specifically, the plating solution can enter the first guide area 21 through the first overflow hole 212 in the first side plate 211 and can enter the second guide area 31 through the second overflow hole 312 in the second side plate 311. The plating solution in the first guide area 21 is guided to the second guide area 31 through the third guide area 11 and then discharged through a plurality of drain holes 32 in the second side wall 3. In the embodiment of the present invention, the overflow plating solution in the first guide area 21 is guided to the second guide area 31 through the third guide area 11 and discharged, so that the number of drain holes 32 to be installed is reduced and the inspection work is reduced. In addition, since the plating solution is discharged from the side, inspection and replacement of the plating solution are convenient.

[0020] 1, in some embodiments, the electroplating tank further includes a third side wall 4 and a fourth side wall 5. Note that when an electroplating facility includes one electroplating tank, the electroplating tank has the third side wall 4 and the fourth side wall 5, and when the electroplating facility includes multiple electroplating tanks, the multiple electroplating tanks are connected in series, in which the electroplating tank located at the head end of the electroplating facility has the third side wall 4, the electroplating tank at the tail end has the fourth side wall 5, and the electroplating tanks connected in the middle have the first side wall 2 and the second side wall 3.

[0021] Specifically, when the electroplating equipment has one electroplating tank, the third guide area 11 is located on the third side wall 4, and the third guide area 11, the first guide area 21 and the second guide area 31 are installed on the bottom plate 1 to form a U-shape. At this time, the drain hole 32 is adjacent to the fourth side wall 5.

[0022] 2, in some embodiments, when the electroplating equipment has a plurality of electroplating tanks, the electroplating tanks between the electroplating tank at the head end and the electroplating tank at the tail end only have a first side wall and a second side wall, and the third guide area 11, the first guide area 21 and the second guide area 31 are arranged on the bottom plate 1 to form an "E" shape. In this case, the drain hole 32 is located at either one or both ends of the second side wall 3 away from the third guide area 11.

[0023] As shown in Fig. 3, in some embodiments, the first overflow hole 212 and the second overflow hole 312 are both elongated holes extending in the horizontal direction and are symmetrically arranged on the first side plate 211 and the second side plate 311, respectively. During electroplating, the thin film is flush with the first overflow hole 212 and the second overflow hole 312, which makes it convenient to drain the plating solution under the thin film. In the embodiments of the present invention, the first overflow hole 212 and the second overflow hole 312 are symmetrically arranged on the first side plate 211 and the second side plate 311, respectively, so that the balance of the plating solution drained from both the left and right ends in the electroplating tank can be maintained.

[0024] 1 and 2, in some embodiments, a plurality of liquid supply holes 33 are formed at both ends of the second side wall 3. In the embodiments of the present invention, by forming a plurality of liquid supply holes 33 at both ends of the second side wall 3, it is possible to maintain a balance in the drainage of plating solution from both the front and rear ends in the electroplating tank.

[0025] As shown in Figures 4 and 5, in some embodiments, one or more liquid supply pipes 12 are provided on the bottom plate 1, located on both sides of the plating area, and the liquid supply pipes 12 communicate with the second guide area 31, and have a plurality of holes formed on the side surfaces. If the electroplating equipment has one electroplating tank, the liquid supply pipes 12 are provided at the inlet end and the outlet end of the electroplating tank, and the liquid supply pipe 12 located at the inlet end is adjacent to the third guide area 11, thereby making the structure of the electroplating tank compact and reducing the footprint of the electroplating tank. Of course, if the electroplating equipment has multiple electroplating tanks, the liquid supply pipe 12 located at the inlet end of the electroplating tank at the neck end is also adjacent to the third guide area 11.

[0026] In this way, by installing liquid supply pipes 12 on both sides of the plating area in the electroplating tank and gently supplying the liquid through multiple holes installed on the side of the liquid supply pipes 12, not only is it possible to ensure that the plating liquid density is the same in each part of the electroplating tank, but it is also possible to avoid the thin film in the plating liquid becoming unstable due to large liquid supply, which could affect the quality of the plating film.

[0027] 4 and 5, a drain valve 321 is attached to each drain hole 32, and a liquid feed valve 331 is attached to each liquid feed hole 33. In the embodiment of the present invention, the inflow and outflow of the plating solution in the electroplating equipment can be controlled at any time by the drain valve 321 and the liquid feed valve 331.

[0028] According to another aspect, the present invention further provides an electroplating production line, which includes the above-mentioned plurality of electroplating tanks, the plurality of electroplating tanks are connected in series, an anode mechanism is installed in each electroplating tank, and the liquid supply pipe 12 at the inlet end of the electroplating tank located at the most upstream side of the electroplating production line is adjacent to the third guide area 11. According to the electroplating production line provided by this practical embodiment, not only can the liquid be drained from the side, but also the number of drain holes 32 installed is reduced, and the inspection work is reduced, so that the inspection and replacement of the plating solution are convenient. In addition, the electroplating production line of the present application has a compact configuration and a rational design, and occupies a small site area.

[0029] The beneficial effects of the present invention are as follows: In the electroplating tank provided by the present invention, the overflow plating solution in the first guiding area 21 is guided and drained to the second guiding area 31 via the third guiding area 11, so the number of drain holes 32 to be installed is reduced, and inspection work is reduced. In addition, since the plating solution is drained from the side, inspection and replacement of the plating solution are convenient.

[0030] In the electroplating tank provided by the present invention, the first overflow hole 212 and the second overflow hole 312 are symmetrically installed in the first side plate 211 and the second side plate 311, respectively, thereby making it possible to maintain a balance in the drainage of plating solution from both the left and right ends of the electroplating tank.

[0031] The electroplating tank provided by the present invention has multiple liquid delivery holes 33 formed on both ends of the second side wall 3, making it possible to maintain a balance in the delivery of plating solution from both the front and rear ends of the electroplating tank.

[0032] The electroplating tank provided by the present invention has liquid supply lines 12 on both sides of the plating area in the electroplating tank, and liquid is slowly supplied through multiple holes formed on the side of the liquid supply lines 12. This not only ensures that the plating solution density is the same in each part of the electroplating tank, but also prevents the thin film in the plating solution from becoming unstable due to excessive liquid supply, which could affect the quality of the plating film.

[0033] The electroplating tank provided by the present invention allows the inflow and outflow of plating solution in the electroplating equipment to be controlled at any time by the drain valve 321 and the liquid supply valve 331 .
