DETAILED DESCRIPTION

[0025] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0026] The semiconductor processing electroplating device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0027] like Figure 1-Figure 5 As shown, the semiconductor processing electroplating device according to the embodiment of the present application may include a frame 10, a conveying assembly 20, a plurality of electroplating tanks 30, a slider 23 and a plurality of clamping assemblies 60.

[0028] The frame 10 may include a first frame body 11 and a second frame body 12 , wherein the first frame body 11 is disposed on the second frame body 12 .

[0029] The conveying assembly 20 may include a first track 21 and a second track 22, wherein the second track 22 is composed of two sub-tracks 221, the first track 21 is disposed between the two sub-tracks 221, the first track 21 is disposed on the first frame 11 through the lifting component 13, and the second track 22 is disposed on the second frame 12. A plurality of electroplating tanks 30 are longitudinally disposed sequentially below the first track 21. The slider 23 is slidably disposed on the conveying assembly 20, and a driving component 90 is disposed on the first track 21.

[0030] It should be noted that the lifting component 13 described in this embodiment can control the vertical movement of the first rail 21. After the first rail 21 moves, it can drive the slider 23 and multiple clamping components 60 thereon to move vertically together, so that the semiconductor 40 on the clamping component 60 enters the corresponding electroplating tank 30, and the electroplating tank 30 performs electroplating on the semiconductor 40.

[0031] It should be noted that the driving component 90 described in this embodiment is capable of controlling the sliding movement of the slider 23 in the first track 21, and this control capability remains unaffected when the slider 23 seamlessly switches between the first track 21 and the second track 22, thereby ensuring the continuity and stability of the operation.

[0032] It can be understood that in the process of the slider 23 entering another sub-track 221 from one sub-track 221, the slider 23 first enters the first track 21, and then moves in the first track 21 under the action of the driving component 90. During the process, the device can electroplate the semiconductor 40, so that the semiconductor 40 can be electroplated during continuous processing, which significantly improves the overall production efficiency, not only reduces labor costs, but also shortens the production cycle.

[0033] A plurality of clamping assemblies 60 are detachable and arranged on the slider 23. The clamping assemblies 60 may include a back plate 61, an upper clamp 62 and two side clamps 63 arranged on the back plate 61. The back plate 61 may include a top plate 611 and two side plates 612. The top plate 611 is vertically arranged at the bottom of the slider 23, and the two side plates 612 are respectively arranged on both sides of the longitudinal direction of the top plate 611. The upper clamp 62 is arranged on the top plate 611 through a rotating component. The two side clamps 63 are respectively arranged on the two side plates 612. The side clamps 63 may include a control rope 631 and a plurality of rollers 632. The control rope 631 is connected to the rotating component, and a mounting block 6321 is movably arranged on one side of the roller 632. The mounting block 6321 is slidably connected to the side plate 612. The control rope 631 is vertically and sequentially arranged to penetrate through the plurality of mounting blocks 6321. The roller 632 is arranged to slide against the corresponding side plate 612.

[0034] It can be understood that the upper clamp 62 and the two side clamps 63 can clamp and fix the upper side and the two longitudinal sides of the semiconductor 40 respectively.

[0035] It should be noted that the rotating component described in this embodiment can drive the upper clamp 62 to rotate, and at the same time can drive the two control ropes 631 to reel in, so that the control rope 631 drives the roller 632 connected thereto to move and achieve clamping of one longitudinal side of the semiconductor 40. The two side clamps 63 can be used in combination to achieve clamping of both longitudinal sides of the semiconductor 40.

[0036] It should be noted that the control rope 631 described in this embodiment can drive the mounting block 6321 connected thereto to move vertically after movement, and the mounting block 6321 drives the roller 632 connected thereto to move vertically, and the roller 632 can rotate during the vertical movement, thereby effectively avoiding potential damage (such as scratches, wear, etc.) to the semiconductor 40 during the movement of the roller 632, and enhancing the ability of the roller 632 to firmly clamp and fix the semiconductor 40.

[0037] Specifically, when electroplating operation is required on the semiconductor 40, the relevant personnel first control the slider 23 to move intermittently on the first track 21 through the driving component 90. When the slider 23 moves intermittently and stops, the first track 21 is controlled to move vertically through the lifting component 13. After the first track 21 moves, it can drive the slider 23 and multiple clamping assemblies 60 thereon to move vertically together, so that the semiconductor 40 on the clamping assembly 60 enters the corresponding electroplating tank 30, and the electroplating tank 30 performs electroplating operation on the semiconductor 40.

[0038] After the semiconductor 40 passes through multiple electroplating tanks 30 for continuous electroplating, the relevant personnel control the first track 21 to reset through the lifting component 13, so that the two ends of the first track 21 are reconnected with the two sub-tracks 221. At this time, the driving component 90 can control the slider 23 to move from the first track 21 to the corresponding sub-track 221, thereby achieving the continuity of the processing of the semiconductor 40. In addition, the next slider 23 can be controlled to enter the first track 21, and the above steps can be repeated to achieve continuous electroplating processing of the semiconductor 40.

[0039] In one embodiment of the present application, Figure 2 As shown, the upper clamp 62 may include a rotating shaft 621 and a plurality of clamping plates 622, wherein the rotating shaft 621 is movably arranged on the top plate 611, a connecting plate 6211 is extended from the rotating shaft 621, the connecting plate 6211 is connected to the rotating component through a connecting rope 70, and a plurality of clamping plates 622 are longitudinally arranged on the rotating shaft 621 in sequence.

[0040] Specifically, the rotating component can control the connection plate 6211 and the rotation axis 621 to rotate relative to the top plate 611 through the connection rope 70, thereby achieving the function of controlling the rotation of multiple clamping plates 622 and realizing the clamping function of multiple clamping plates 622 and the top plate 611 on the upper side of the semiconductor 40.

[0041] Furthermore, if Figure 3 and Figure 4As shown, the rotating component may include a winding shaft 80, which is arranged in a accommodating cavity 6111 inside the top plate 611, and a first motor 81 is provided at the end of the winding shaft 80. The connecting rope 70 passes through the accommodating cavity 6111 and is connected to the small diameter portion in the middle of the winding shaft 80, and the two control ropes 631 respectively pass through the accommodating cavity 6111 and are connected to the large diameter portions on both sides of the winding shaft 80.

[0042] It should be noted that the winding shaft 80 described in this embodiment has large diameter parts on both sides and a small diameter part in the middle, so that the winding movement distances of the connecting rope 70 and the control rope 631 on the winding shaft 80 are different, so that the side clamp 63 can adapt to the clamping of semiconductors 40 of different lengths.

[0043] Specifically, when it is necessary to control the clamping assembly 60 to clamp the semiconductor 40, the first motor 81 is started first. The first motor 81 drives the winding shaft 80 to rotate, so that the connecting rope 70 and the two control ropes 631 can be wound on the winding shaft 80, so that the connecting rope 70 drives the rotating shaft 621 to rotate, and the control rope 631 drives the multiple mounting blocks 6321 connected thereto to move vertically, thereby realizing the function of clamping and fixing the upper side and both longitudinal sides of the semiconductor 40.

[0044] Furthermore, if Figure 2 , Figure 3 and Figure 4 As shown, the diameters of the multiple rollers 632 on the side plate 612 decrease from top to bottom, and multiple baffles 6121 for limiting the rollers 632 are vertically arranged on the side plate 612, and the distances between the multiple baffles 6121 and the side plate 612 decrease from top to bottom.

[0045] It is understandable that the multiple baffles 6121 are capable of limiting the corresponding rollers 632 respectively, so that the multiple rollers 632 are located at the corresponding baffles 6121 when moving vertically, which helps to stably clamp the semiconductor 40.

[0046] In one embodiment of the present application, Figure 3 As shown, the driving component 90 may include a second motor 91, a meshing rack 92 and a gear 93, wherein the second motor 91 is arranged on a mounting seat 211 outside the first track 21, and a moving block 912 is arranged at the output end of the second motor 91 through a movable shaft 911, the moving block 912 passes through the first track 21 and has a groove 9121 at one end, a moving plate 9123 is arranged in the groove 9121 through a spring 9122, and the moving plate 9123 is arranged against one longitudinal side of the slider 23. The gear 93 is sleeved on the outer side of the movable shaft 911, and the rack 92 is arranged on the first track 21. One longitudinal side of the slider 23 is arranged in an arc shape.

[0047] It should be noted that when the slider 23 described in this embodiment enters the first track 21, the curved side of the slider 23 first contacts the movable plate 9123, and in the process of the slider 23 entering the first track 21, the movable plate 9123 can first move in the direction of the groove 9121 and compress the spring 9122. When the slider 23 moves and separates from the movable plate 9123, the movable plate 9123 moves and resets under the action of the spring 9122. At this time, the movable plate 9123 can push the slider 23 to move in the first track 21 under the control of the driving component 90.

[0048] Specifically, when the relevant personnel controls the slider 23 to move on the first track 21 through the driving component 90, the second motor 91 is started first, and the second motor 91 drives the movable shaft 911 to rotate. The rotation of the movable shaft 911 can drive the gear 93 to rotate. Under the action of the rack 92, the mounting seat 211, the second motor 91, the movable shaft 911, the gear 93, the moving block 912 and the moving plate 9123 will move longitudinally linearly together. During the process, the moving plate 9123 can push the slider 23 to move in the first track 21.

[0049] In summary, the semiconductor processing electroplating device in the embodiment of the present application, through the provided driving components, can enable the semiconductor to be electroplated during continuous processing, thereby significantly improving the overall production efficiency. Through the provided clamping components, the semiconductor can be fixed quickly and stably, which can effectively reduce the problem of uneven electroplating caused by material deformation during the electroplating process.
