Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.
[0027] It should be noted that the terms "first", "second", etc. in the description, claims and the above-mentioned drawings of the present utility model are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence.
[0028] The present utility model provides an electroplating device 100 for electroplating workpieces such as electronic devices. Please refer to Figures 1 to 4 , the electroplating device 100 includes an electroplating container 10, a shielding member 30 and a fixing jig 40. The electroplating container 10 has a cavity 11 for containing electroplating solution. The upper side of the cavity 11 is open, and an anode member 20 is arranged in the cavity 11. The anode member 20 can conduct the power supply member to cause an electrolytic reaction in the electroplating solution, so that a required metal or alloy layer is deposited on the surface of the workpiece immersed in the electroplating solution.
[0029] Please refer to Figure 3 , the cavity 11 has two side walls 12 arranged opposite to each other in the transverse direction. The two side walls 12 are distributed at both ends of the anode member 20 in the transverse direction. A first guide rail 121 and a second guide rail 122 extending in the up and down direction are respectively formed on each side wall 12. The first guide rail 121 and the second guide rail 122 are arranged side by side in the front and back direction. The anode member 20, the first guide rail 121 and the second guide rail 122 are arranged in sequence from front to back. The first guide rail 121 and the second guide rail 122 can be track members assembled on the surface of the side wall 12, or can be recessed from the side wall 12.
[0030] The shielding member 30 is floatingly arranged in the cavity 11 and is arranged in front of the anode member 20. The shielding member 30 includes a bottom plate 31 and a baffle 32 fixed to the front side of the bottom plate 31. The baffle 32 faces the anode member 20 and is slidably mounted on the electroplating container 10 along the first guide rail 121. The bottom plate 31 extends backward from the lower end of the baffle 32 to the lower end of the second guide rail 122. It can be understood that the shielding member 30 should be made of an insulating material.
[0031] The fixing fixture 40 is used for installing a workpiece. The fixing fixture 40 is slidably arranged up and down along the second guide rail 122 in the cavity 11. At both ends of the fixing fixture 40 in the transverse direction, clamping portions 41 are respectively arranged. In the second guide rail 122, a plurality of clamping and mating portions are arranged at intervals in the up and down direction. The clamping portion 41 and the clamping and mating portion can be a mating clamping hole and a clamping block, or an elastic convex block and a clamping groove. Thus, the clamping portion 41 is slidably arranged in the second guide rail 122 and is clamped and mated with one of the plurality of clamping and mating portions, so that the fixing fixture 40 is adjustably installed in the electroplating container 10 in the up and down direction. The lower end of the fixing fixture 40 is used to press downward against the upper side of the bottom plate 31, so that the shielding member 30 is pressed down into the electroplating solution. Preferably, there is a gap between the bottom plate 31 and the bottom of the cavity 11. That is to say, no matter where the shielding member 30 is pressed down, there is a gap at its bottom to avoid shielding the electroplating components.
[0032] In this embodiment, when electroplating operation is required, the workpiece can be installed on the fixing fixture 40, and the fixing fixture 40 can be pressed down along the second guide rail 122 to an appropriate depth according to the size of the workpiece, and the workpiece is immersed in the electroplating solution. At the same time, the structure of the fixing fixture 40 itself is used to press against the bottom plate 31 of the shielding member 30, so that the baffle 32 of the shielding member 30 correspondingly shields the edge of the workpiece, achieving the effect of improving the edge effect. Since the fixing fixture 40 is adjustably installed on the electroplating container 10 and correspondingly presses against the bottom plate 31 of the shielding member 30, the edge position of the workpiece installed on the fixing fixture 40 corresponds to the position of the baffle 32 of the shielding member 30 and is immersed in the electroplating solution, realizing that the shielding member 30 is applicable to workpieces of different sizes and specifications, and avoiding the phenomenon that the thin workpiece is bent and deformed by the shielding member 30. The electroplating quality and the versatility of the electroplating device 100 are improved.
[0033] There can be various structures for the fixing fixture 40 to install the workpiece. In this embodiment, please refer to Figure 4 , the fixing fixture 40 includes a cross bar 42 extending in the transverse direction. At both ends of the cross bar 42, the clamping portions 41 are respectively arranged. A fixing and installing member 44 is arranged on the lower side of the cross bar 42. The fixing and installing member 44 is used for fixing the workpiece. Two vertical bars 43 are also detachably connected to the lower side of the cross bar 42. The two vertical bars 43 are respectively arranged on both sides of the fixing and installing member 44 in the transverse direction. Thus, the workpiece is fixed by the cross bar 42, and at the same time, the vertical bars 43 corresponding to the size of the workpiece are used to abut against the bottom plate 31 of the shielding member 30. That is to say, the height of the vertical bar 43 should be greater than the workpiece and be basically the same as the workpiece. In this way, the baffle 32 can exactly shield the edge of the workpiece and avoid the phenomenon that the workpiece directly presses against the shielding member 30, resulting in the bending and deformation of the thin workpiece.
[0034] Preferably, a plurality of jigs are provided on the lower side of the cross bar 42. The plurality of jigs are arranged at intervals in the transverse direction on the cross bar 42. The plurality of jigs include two first jigs 451 located at both ends in the transverse direction, and a plurality of second jigs 452 provided between the two first jigs 451. Each of the first jigs 451 is respectively used for clamping one of the vertical rods 43, and the plurality of second jigs 452 serve as the fixed mounting members 44 for clamping the workpiece. In this way, the workpiece is clamped and fixed by the second jigs 452, and the vertical rods 43 are fixed by the first jigs 451.
[0035] In order to further improve the versatility of the fixing jig 40, the plurality of second jigs 452 are adjustably mounted on the cross bar 42 in the transverse direction. In this way, the fixing jig 40 can fix workpieces of various specifications with different transverse dimensions.
[0036] Optionally, the electroplating device 100 includes multiple sets of vertical rod groups. Each set of vertical rod groups includes two vertical rods 43 with the same length. The lengths of the vertical rods 43 in multiple sets of vertical rod groups are different. The lower side of the cross bar 42 is alternatively connected to one of the multiple sets of vertical rod groups. In this way, the appropriate vertical rods 43 can be selected and installed and fixed according to the size of the workpiece installed on the fixing jig 40, so that when the fixing jig 40 cooperates with the shielding member 30, the lower ends of the vertical rods 43 rather than the workpiece itself are in contact with the bottom plate 31.
[0037] Please refer to Figure 4 , in order to enable the shielding member 30 to smoothly slide and cooperate with the first guide rail 121, two guiding members 321 are provided at the upper end of the baffle 32. The two guiding members 321 are distributed at both ends of the baffle 32 in the transverse direction. Each of the guiding members 321 respectively slidably cooperates with each of the first guide rails 121. The specific structure of the guiding member 321 corresponds to that of the first guide rail 121. For example, it can be a guiding wheel, a guiding block, etc.
[0038] Furthermore, a pulling rope 323 is fixed on each of the guiding members 321. The other end of the pulling rope 323 is detachably connected to a counterweight 324. A pulley 322 is fixed at the upper end of each of the first guide rails 121. The pulling rope 323 bypasses the corresponding pulley 322. In this embodiment, the appropriate counterweight 324 can be selected by comprehensively considering factors such as the weight of the shielding member 30 itself and the depth of the electroplating solution in the electroplating tank. When the shielding member 30 is not affected by other external forces, the counterweight 324 pulls the shielding member 30 to a suitable position below the surface of the electroplating solution. In this way, it will not cause some workpieces with smaller height dimensions to be unable to cooperate with the shielding member 30 due to the too low initial position of the shielding member 30. Thereby further improving the versatility of the electroplating device 100.
[0039] Preferably, when the shielding member 30 slides to the upper end of the first guide rail 121, each of the guiding members 321 is limited and abutted against the corresponding pulley 322. In this way, on the one hand, the pulley 322 plays a guiding role, and on the other hand, it also plays a role in limiting the guiding member 321 to prevent the shielding member 30 from being pulled out.
[0040] Preferably, the size of the baffle 32 in the up and down direction is greater than or equal to 90 mm and less than or equal to 160 mm. Preferably, the size of the baffle 32 is 150 mm, so as to play a good role in improving the edge effect.
[0041] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, those of ordinary skill in the art can make other different forms of changes or modifications without making creative efforts, and all of them should fall within the protection scope of the present invention.
