Description

[Technical field]

[0001] The present invention relates to the technical field of electroplating equipment, and in particular to a galvanic electroplating equipment with double-sided deposition function. [Background technology]

[0002] As an example of current electroplating devices, utility model CN214991962U discloses a galvanic electroplating device for electroplating the surface of a flexible film substrate. In this technical solution, when the conductive tape is looped around the outside of the film, the conductive tape enters the plating solution, and the plating solution is exposed to the outside of the solution together with the conductive tape, so that the plating solution on the conductive tape needs to be processed, for example, buffed to remove the copper plating, and the specification states that "a first main roller and a second main roller are provided in the plating tank, and the plating film is drawn around the first main roller, then drawn around the second main roller in the opposite direction, and passes through the plating solution pool." As can be seen from this description, it is necessary to provide an overflow tank 313 corresponding to the left conductive tape 331, and the plating solution on the conductive tape is processed in the overflow tank 313, and the conductive tape passes from the plating tank, and the plating solution in the plating tank overflows into the overflow tank 313, while the right conductive tape 331 can process the plating solution on the conductive tape above it, and no conductive tape is required. Therefore, in the technical solution of this utility model, the cost is increased by providing an overflow tank for the left conductive tape, and the conductive tape passes from inside the plating tank, making the structure complicated and difficult to industrialize. Summary of the Invention [Problem to be solved by the invention]

[0003] The present invention provides a galvanic electroplating apparatus with double-sided deposition function, which does not require the conductive tape to pass through the plating tank and does not require the addition of a corresponding overflow tank to collect the plating solution, thus saving the input of the apparatus and improving the safety of the plating tank. [Means for solving the problem]

[0004] In order to solve the above problems, the present invention adopts the following technical solutions.

[0005] A galvanic electroplating apparatus having a double-sided film deposition function includes a plating tank and a film transport means, a first main roller and a second main roller are provided in the plating tank, the first main roller and the second main roller deposit films on two sides of a film, respectively, a conductive tape is provided around both the first main roller and the second main roller, the conductive tape is drawn in a circular manner while being in close contact with a portion of an outer surface of the film, an arc-shaped anode plate is provided around both the first main roller and the second main roller, the anode plate is connected to the positive electrode of a plating power source, and the conductive tape is connected to the negative electrode of the plating power source, and the film transport means guides one side of the film to be drawn around the left side of the first main roller and pulled out from the right side of the first main roller, and guides the other side of the film to be drawn around the right side of the second main roller and pulled out from the left side of the second main roller.

[0006] Furthermore, the film transport means includes an unwinding means and a winding means, and the unwinding means unwinds the film and the winding means winds up the deposited film, thereby completing the entire electroplating process.

[0007] Furthermore, the unwinding means may be provided between the first main roller and the second main roller, and specifically, may select an upper area between the first main roller and the second main roller. The first main roller is located to the right of the second main roller.

[0013] In order to more clearly explain the technical solutions in the embodiments of the present invention, the following briefly introduces drawings that need to be used to describe the embodiments or prior art. Obviously, the drawings described below are merely some embodiments of the present invention, and those skilled in the art can also derive other drawings based on these drawings without exerting creative efforts. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] In order to facilitate understanding by those skilled in the art, the present invention will be further described below in conjunction with examples and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. EXAMPLES

[0016] The galvanic electroplating apparatus having a double-sided film deposition function shown in Figures 1 to 3 includes a plating tank 1 and a film 100 transport means, and a first main roller 201 and a second main roller 202 are provided in the plating tank 1. The first main roller 201 and the second main roller 202 deposit films on two sides of the film 100, respectively, and a conductive tape 3 is provided around both the first main roller 201 and the second main roller 202, and the conductive tape 3 is circulated around while being in close contact with a part of the outer surface of the film 100. An arc-shaped anode plate 4 is provided around both the first main roller 201 and the second main roller 202, and the anode plate 4 is connected to the positive pole of a plating power source, and the conductive tape 3 is connected to the negative pole of the plating power source. The film 100 transport means guides one side of the film 100 so that it is pulled around the left side of the first main roller 201 and drawn out from the right side of the first main roller 201, and guides the other side of the film 100 so that it is pulled around the right side of the second main roller 202 and drawn out from the left side of the second main roller 202.

[0017] As shown in Figure 1 or Figure 2, the first main roller and then the second main roller are lined up from the right side of the plating tank (from right to left), so that the uncoated film is pulled around the right side of the first main roller, passes above the first main roller, and is pulled out from the left side of the first main roller, then the film is pulled around the right side of the second main roller, passes above the second main roller, and is pulled out from the left side of the second main roller, completing the film pulling process.

[0018] In this embodiment, the film 100 transport means includes an unwinding means 5 and a winding means 9, and the film 100 is unwound by the unwinding means 5 and wound up by the winding means 9 to complete the entire electroplating process. Specifically, the unwinding means 5 is provided between the first main roller 201 and the second main roller 202. Specifically, an upper area between the first main roller 201 and the second main roller 202 may be selected, and since the film 100 is first drawn around the left side of the first main roller 201, it is preferable that the unwinding means 5 is provided above the area close to the left side of the first main roller 201.

[0019] Specifically, the electroplating process is as follows: the film 100 is routed around the left side of the first main roller 201 and is pulled out from the right side of the first main roller 201. The conductive tape 3 is routed and pulled out in the area above the first main roller 201, and the conductive tape 3 pulled out from the right side of the first main roller 201 is routed around the left side of the second main roller 202 and is pulled out from the right side of the second main roller 202. The conductive tape 3 is routed and pulled out in the area above the second main roller 202, and the conductive tape 3 wipes the conductive tape 3 located in the area above the first main roller 201 and the second main roller 202, preventing the plating solution carried out by the conductive tape 3 from the plating tank 1 from leaking onto the rollers or the film 100. In the process of installing the conductive tape 3, the conductive tape 3 does not pass through the plating tank 1, and there is no need to add an overflow tank. Similarly, the anode plate 4 near the first main roller 201 (or the second main roller 202) is connected to the positive pole of a plating power supply (not shown), and the conductive tape 3 on the first main roller 201 (or the second main roller 202) is connected to the negative pole of the plating power supply (not shown), so that cations in the electroplating solution can be deposited on the film 100.

[0020] Specifically, the unwinding means 5 includes an unwinding shaft 51 for unwinding the film 100, and support shafts 52 provided on both ends of the unwinding shaft 51. The unwinding shaft 51 is driven by a motor (not shown), and the support shaft 52 may be driven by a motor (not shown), and can rotate the unwinding shaft 51 by being driven by the motor (not shown). This completes the unwinding of the film 100, and can tilt the support shaft 52 within a certain range by being driven by the motor. By tilting the support shaft 52, the height of the unwinding shaft 51 can be adjusted, and thus the supply angle of the film 100 (output by the unwinding operation) can be adjusted, and the film 100 can be easily unfolded.

[0021] In the present invention, the electroplating apparatus further includes a water rinsing tank 6 and an oxidation prevention tank 7, and the film 100 pulled out from the left side of the second main roller 202 as described above further passes through the water rinsing tank 6 and the oxidation prevention tank 7 in order.

[0022] Specifically, a static eliminator 8 is provided between the water washing tank 6 and the antioxidant tank 7, and the static eliminator 8 may be used to eliminate static electricity generated in the process of transporting the film 100. A static eliminator 8 of a conventional model may be selected and combined.

[0023] The specific operation process is as follows: an electroplating solution is stored in the plating tank, distilled water is stored in the water washing tank, and an antioxidant solution is stored in the antioxidant tank. When the film coil is unwound by the unwinding means, the film is routed from the left side of the first main roller and unwound from the right side of the first main roller, during which the film is electroplated by the conductive tape on the first main roller, the film unwound from the first main roller is routed from the right side of the second main roller and unwound from the left side of the second main roller, during which the film is electroplated by the conductive tape on the second main roller, the film unwound from the second main roller is wiped (after the electroplating solution is removed), reaches the water washing tank, is washed with water, and then reaches the antioxidant tank, is subjected to an antioxidant treatment, and is further subjected to operations such as drying to complete the process of electroplating the film.

[0024] The above embodiments are preferred implementations of the present invention. In addition, the present invention may be implemented in other ways. As long as they do not deviate from the concept of the technical solution, any obvious substitutions are within the scope of protection of the present invention.

[0025] The galvanic electroplating apparatus with double-sided film deposition function of the present invention adjusts the position and routing of the unwinding means so that the film does not need to pass through the plating tank and there is no need to combine it with a corresponding overflow tank, reducing the input of the apparatus and improving the safety of the plating tank. As a result, the galvanic electroplating apparatus with double-sided film deposition function of the present invention is practical. [Explanation of symbols]
