Description

Technical Field

[0001] The utility model relates to the technical field of water electroplating, in particular to a copper dissolving tank. Background Art

[0002] At present, the preparation of composite copper foil is usually carried out by water electroplating. During the water electroplating process, the copper ions in the plating solution in the electroplating tank are reduced to copper atoms on the surface of the film and attached to the surface of the film to form a coating. The quality of the plating solution will affect the quality of the product after water electroplating. In the water electroplating process, the plating solution with a stable copper ion concentration needs to be continuously passed into the electroplating tank. Before the plating solution enters the electroplating tank, it is usually necessary to dissolve the copper material into a plating solution containing copper ions.

[0003] The existing copper dissolving method is to manually put the copper material directly from the top of the copper dissolving tank into the tank body, and the copper material is dissolved in the sulfuric acid solution in the tank body to form a plating solution containing copper ions, and then the plating solution containing copper ions is transported to the electroplating tank. Due to the manual feeding method, this method has a low degree of automation, increases labor costs, and cannot control the copper dissolving speed, so it is impossible to ensure the stability of the copper ion concentration in the plating solution, so that the copper ion concentration in the plating solution is sometimes high and sometimes low, which easily leads to uneven plating of the film when the film is electroplated in the electroplating tank.

[0034] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0035] Please refer to Figure 1 and Figure 2A copper dissolving tank provided by an embodiment of the utility model includes a tank body 10 for containing sulfuric acid solution and a cover body 20 covered on the top of the tank body 10.

[0036] Combination Figure 4 As shown, a feed port 21 communicating with the interior of the tank body 10 is provided on the cover body 20, that is, on the top of the cover body 20. A conveying mechanism 30 and a supporting mechanism 40 are provided at the feed port 21.

[0037] Combination Figure 3 , Figures 5 to 8 As shown, the conveying mechanism 30 includes a driving wheel 31, a motor 32 and an abutment assembly.

[0038] The motor 32 is arranged on the cover body 20, i.e., the top of the cover body 20, through the motor seat 321. The motor seat 321 is located on the right side of the feed port 21. The driving wheel 31 is located on the left side of the motor 32 and is connected to the motor 32. The driving wheel 31 is sleeved on the outer circumference of the driving wheel shaft 311, and one end of the driving wheel shaft 311, i.e., the end close to the motor 32, is connected to the output end of the motor 32. The motor 32 is used to drive the driving wheel shaft 311 to rotate, thereby driving the driving wheel 31 to rotate. The driving wheel 31 is used to drive the copper wire 100 to move downward so that the copper wire 100 passes through the feed port 21 and enters the interior of the tank body 10.

[0039] The abutment assembly is disposed on the cover body 20, i.e., on the top of the cover body 20. The abutment assembly is located in front of the driving wheel 31 and opposite to the driving wheel 31. There is a gap between the driving wheel 31 and the abutment assembly for the copper wire 100 to pass through, and the gap is located above the feed port 21. The abutment assembly is used to press the copper wire 100 passing through the gap against the outer peripheral surface of the driving wheel 31.

[0040] Specifically, the abutting assembly includes a pressure wheel 33 , a pressure wheel mounting seat 34 and a pressure wheel driving member 35 .

[0041] The pressure wheel driving member 35 is arranged on the top of the cover body 20 through the base 351. The base 351 is located in front of the feed port 21. The pressure wheel mounting seat 34 is located between the driving wheel 31 and the pressure wheel driving member 35. The first end of the pressure wheel mounting seat 34 is connected to the pressure wheel driving member 35, and the pressure wheel 33 is rotatably arranged at the second end of the pressure wheel mounting seat 34. The pressure wheel 33 and the driving wheel 31 are arranged front and back relative to each other. There is the above-mentioned gap between the pressure wheel 33 and the driving wheel 31. The pressure wheel driving member 35 is used to drive the pressure wheel mounting seat 34 to move in the direction close to or away from the driving wheel 31, thereby driving the pressure wheel 33 to move in the direction close to or away from the driving wheel 31. In actual application, when the copper wire 100 passes through the gap between the driving wheel 31 and the pressure wheel 33, the pressure wheel driving member 35 drives the pressure wheel 33 to move toward the driving wheel 31, so that the copper wire 100 can be pressed against the driving wheel 31 by the pressure wheel 33, thereby increasing the friction between the driving wheel 31 and the copper wire 100, so that the copper wire 100 can be driven downward by the rotation of the driving wheel 31, so that the copper wire 100 can enter the interior of the tank body 10 through the feed port 21.

[0042] In this embodiment, the pressure roller drive member 35 is a cylinder, and the first end of the pressure roller mounting seat 34 is connected to the output end of the cylinder. It can be understood that the pressure roller drive member 35 can also be a servo electric cylinder, a hydraulic cylinder, etc., and the first end of the pressure roller mounting seat 34 is connected to the output end of the servo electric cylinder or the hydraulic cylinder. In other embodiments, the pressure roller drive member 35 can also be a motor + screw nut transmission assembly, in which case the first end of the pressure roller mounting seat 34 is connected to the nut of the screw nut transmission assembly, and the pressure roller drive member 35 can also be, for example, a linear motor, in which case the first end of the pressure roller mounting seat 34 is arranged on the top of the linear motor through a connecting block.

[0043] A recess 341 is provided at the second end of the pressure wheel mounting seat 34, and a pressure wheel shaft 331 is rotatably provided between the inner walls on both sides of the recess 341. The pressure wheel 33 is located in the recess 341 and is sleeved on the outer circumference of the pressure wheel shaft 331. The pressure wheel 33 partially protrudes from the top end, the bottom end and the second end of the pressure wheel mounting seat 34.

[0044] In this embodiment, two mounting holes are respectively provided on the inner walls on both sides of the recess 341 , and the two ends of the pressure wheel shaft 331 are rotatably disposed in the two mounting holes.

[0045] The outer circumference of the driving wheel 31 has an annular driving wheel recessed area 312, and the outer circumference of the pressure wheel 33 has an annular pressure wheel recessed area 332. The pressure wheel recessed area 332 corresponds to the driving wheel recessed area 312, and the cross-sectional shapes of the bottoms of the driving wheel recessed area 312 and the pressure wheel recessed area 332 are both arc-shaped. In actual application, the copper wire 100 can be passed between the bottom of the driving wheel recessed area 312 and the bottom of the pressure wheel recessed area 332. When the pressure wheel 33 is driven by the pressure wheel driving member 35 to move toward the driving wheel 31, the copper wire 100 can be pressed against the bottom of the driving wheel recessed area 312 through the bottom of the pressure wheel recessed area 332 of the pressure wheel 33. The driving wheel recessed area 312, the pressure wheel recessed area 332 and the bottom of the driving wheel recessed area 312 and the pressure wheel recessed area 332 are all arc-shaped. Through this structure, when the copper wire 100 is pressed against the bottom of the driving wheel recessed area 312 through the bottom of the pressure wheel recessed area 332 of the pressure wheel 33, the copper wire 100 can be confined to the middle position of the bottom of the driving wheel recessed area 312, thereby preventing the copper wire 100 from sliding along the axial direction of the driving wheel 31 on the outer peripheral surface of the driving wheel 31.

[0046] The sum of the maximum depths of the pressure wheel recess 332 and the driving wheel recess 312 is less than or equal to the radius of the copper wire 100 , so that the copper wire 100 can be pressed against the bottom of the driving wheel recess 312 through the bottom of the pressure wheel recess 332 of the pressure wheel 33 .

[0047] Combination Figure 5 , Figure 6 , Fig. 9 and Fig.10 As shown, the support mechanism 40 includes two support seats 41 arranged opposite to each other on the left and right, a support shaft 42 and a reel 43 for winding the copper wire 100 .

[0048] Two support seats 41 are respectively arranged on the cover body 20, that is, the top of the cover body 20. The two ends of the support shaft 42 are respectively arranged at the top ends of the two support seats 41, and the support shaft 42 can rotate relative to the two support seats 41. The reel 43 is an I-shaped structure, and the reel 43 is sleeved on the outer periphery of the support shaft 42 and is located between the two support seats 41. The feed port 21, the driving wheel 31, the motor 32, the motor seat 321, the pressure wheel 33 and the pressure wheel mounting seat 34 are all located between the two support seats 41, the feed port 21 is close to the support seat 41 located on the left, the pressure wheel driving member 35 and the base 351 are located in front between the two support seats 41, and the driving wheel 31, the motor 32, the motor seat 321, the pressure wheel 33, the pressure wheel mounting seat 34 and the pressure wheel driving member 35 are all located below the reel 43. When the copper wire 100 is wound on the reel 43, one end of the copper wire 100 corresponds to the gap.

[0049] In this embodiment, the top of the support seat 41 is provided with a groove 411 and a rotation groove 412 in sequence along the direction away from the feed port 21. The length directions of the groove 411 and the rotation groove 412 are the same as the width direction of the support seat 41. One side of the groove 411 extends to the side of the support seat 41 close to the feed port 21, and the other side of the groove 411 is connected to the rotation groove 412. The two ends of the support shaft 42 are respectively located in the grooves 411 of the two support seats 41 and are respectively connected to two circular rotating heads 421, and the two rotating heads 421 are respectively placed in the rotation grooves 412 of the two support seats 41 and the two rotating heads 421 parts protrude from the top of the corresponding support seat 41. The two rotating heads 421 can rotate in the corresponding rotation grooves 412 respectively. When the copper wire 100 is driven to move downward by the driving wheel 31, the copper wire 100 will drive the reel 43 to rotate. With the rotation of the reel 43, the copper wire 100 can be unwound. The support shaft 42 will rotate synchronously with the reel 43. The rotation of the support shaft 42 can drive the two rotating heads 421 to rotate in the corresponding rotating grooves 412 respectively. The length of the groove 411 is greater than the outer diameter of the support shaft 42, so that it will not interfere with the rotation of the support shaft 42. The depth and length of the groove 411 are both less than the depth and length of the rotating groove 412, so that the inner wall of the rotating groove 412 close to the groove 411 can limit the rotating head 421. When the rotating head 421 rotates in the corresponding rotating groove 412, the rotating head 421 will not be separated from the corresponding rotating groove 412. The length of the rotating groove 412 is greater than the outer diameter of the rotating head 421, and the width of the rotating groove 412 is adapted to the outer diameter of the rotating head 421. The two ends of the bottom of the rotating groove 412 respectively have an arc surface 4121, and the arc surface 4121 is adapted to the outer peripheral surface of the corresponding rotating head 421. This structure makes it easy for the support shaft 42 to drive the rotating head 421 to rotate in the corresponding rotating groove 412.

[0050] Through the above structure, when the utility model is actually used, the tank body 10 contains sulfuric acid solution, and the copper wire 100 is first wound on the reel 43, and then one end of the copper wire 100 passes through the gap between the driving wheel 31 and the pressure wheel 33 and is placed in the feed port 21. Then, the pressure wheel 33 is driven by the pressure wheel driving member 35 to move toward the direction close to the driving wheel 31, so that the copper wire 100 can be pressed against the bottom of the driving wheel recessed area 312 of the driving wheel 31 through the bottom of the pressure wheel recessed area 332 of the pressure wheel 33, thereby increasing the friction between the driving wheel 31 and the copper wire 100, and then the driving wheel 31 is driven to rotate by the motor 32, and the rotation of the driving wheel 31 can drive the copper wire 100 to move downward, so that the copper wire 100 can enter the interior of the tank body 10 through the feed port 21, as shown in FIG. This is to deliver the copper wire 100 into the tank body 10, and then the copper wire 100 is dissolved in the sulfuric acid solution in the tank body 10 to form a plating solution containing copper ions. In this process, the motor 32 is used to drive the driving wheel 31 to rotate, so that the speed of the driving wheel 31 can be controlled by controlling the speed of the motor 32, so as to control the feeding speed of the copper wire 100, so that the speed of copper dissolution can be controlled, thereby ensuring that the concentration of copper ions in the plating solution is stable and the uniformity of the film coating is ensured.

[0051] The utility model is provided with a conveying mechanism 30, and the conveying mechanism 30 includes a driving wheel 31, a motor 32 and an abutment assembly, so that the copper wire 100 can be automatically fed into the interior of the tank body 100 through the feed port 21, with a high degree of automation, reducing labor costs, and the feed speed of the copper wire 100 can be controlled by controlling the rotation speed of the motor 32, so that the copper dissolving speed can be controlled, thereby ensuring that the concentration of copper ions in the plating solution is stable and ensuring the uniformity of the coating of the thin film.

[0052] The utility model further comprises a controller, the motor 32 is electrically connected to the controller, and the controller is used to control the rotation speed of the motor 32 .

[0053] In the present embodiment, a copper ion detector is provided in the tank body 10, and the copper ion detector is electrically connected to the controller. The copper ion detector is used to detect the concentration of copper ions in the plating solution in the tank body 10. In actual application, the copper ion detector is immersed in a sulfuric acid solution. The concentration of copper ions in the tank body 10 can be detected by the copper ion detector. After the concentration data of the copper ions are output to the controller, the controller adjusts the speed of the motor 32 according to the concentration data of the copper ions. For example, when the copper ion concentration is low, the speed of the motor 32 is increased by the controller, so that the feeding speed of the copper wire 100 can be increased, thereby increasing the copper dissolving speed. When the copper ion concentration is high, the speed of the motor 32 is reduced by the controller, so that the feeding speed of the copper wire 100 can be reduced, thereby reducing the copper dissolving speed. In this way, the consistency of the copper ion concentration in the plating solution can be ensured by adjusting the speed of the motor 32.

[0054] In this embodiment, there are multiple feed ports 21, for example four, and the four feed ports 21 are distributed in a ring-shaped manner around the center of the cover body 20. Correspondingly, there are four conveying mechanisms 30 and four supporting mechanisms 40 respectively. It can be understood that the number of feed ports 21, conveying mechanisms 30 and supporting mechanisms 40 can be other numbers and can be set according to actual conditions.

[0055] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
