Based on the above, the application provides an MLCC high-yield product electroplating feeding device and a feeding method.
Referring to fig. 1 and 2, fig. 1 is a schematic top view and fig. 2 is a schematic side view of an MLCC high-throughput electroplating feeding device according to an embodiment of the present application, the MLCC high-throughput electroplating feeding device includes a water tank 10 and a roller screen assembly 20, the roller screen assembly 20 is transversely erected in the water tank 10, the roller screen assembly 20 includes a feeding port 21, and the feeding port 21 is used for feeding electroplating material 101 into the roller screen assembly 20. A sealing cover can be arranged at the feeding port 21, and the feeding port 21 can be closed after feeding is finished.
In use, water may be initially supplied to tank 10 and then drum screen assembly 20 is submerged in tank 10 such that the water in tank 10 at least partially submerges drum screen assembly 20. It will be appreciated that water in the water tank may enter the interior of the roller screen assembly 20 through the mesh openings of the roller screen assembly 20. Finally, the plating material 101 is poured into the roller screen 23 from the feed opening 21 to complete the feeding. The plating material 101 may include MLCC semi-finished products and conductive balls, which may enhance the conductivity of the plating solution in subsequent plating processes. In this embodiment, because of receiving the buffering of water when electroplating material 101 falls into roller screen assembly 20, can avoid electroplating material 101 collision each other and electroplating material 101 and roller screen assembly 20 inner wall between the collision to can reduce damage, porcelain damage defect, improve the product yield. The embodiment can be widely applied to large-size high-capacity MLCC, for example, the specification of 0603 (1.6mm 0.8mm) and above, and the capacity value can be 100000pF and above.
In one embodiment, with continued reference to fig. 1 and 2, the roller screen assembly 20 may include a support frame 22, a roller screen 23, and a drive assembly 24. The roller screen 23 comprises a first enclosing plate 231, a second enclosing plate 232 and an enclosing plate 233, the first enclosing plate 231 and the second enclosing plate 232 are arranged oppositely, the enclosing plate 233 is connected with the first enclosing plate 231 and the second enclosing plate 232 to form an enclosing region, and the feeding port 21 is arranged on the enclosing plate 233. The plating material 101 may be poured from the feed opening 21 into the enclosure. The side coaming 233 is provided with meshes, and the size of the meshes is smaller than that of the electroplating material 101, so that on one hand, water in the water tank can enter the roller screen 23, and on the other hand, the electroplating material 101 is prevented from leaking into the water tank from the meshes. The mesh is preferably irregular in shape because it is easily plugged by the conductive balls or the MLCC semi-finished product when the mesh is circular or regular rectangular. The roller screen 23 is rotatably connected to the bracket 22 along a horizontal axis, and the driving assembly 24 is connected to the roller screen 23 for driving the roller screen 23 to rotate about the horizontal axis. The plating material 101 may be inverted by rotation of the roller screen 23 to enhance plating uniformity during the plating process. As an example, the lateral enclosing plate 233 has a regular hexagonal cross section, the feeding opening 21 is provided on one of the sides of the lateral enclosing plate 233, and the feeding opening 21 is rotated to a suitable position for feeding, for example, to the position shown in fig. 2.

For example, the rotating shaft Z may extend through the first enclosing plate 231, pass through the enclosing region and then extend through the second enclosing plate 232, and both ends of the rotating shaft Z are connected to the bracket 22. The roller screen 23 can rotate relative to the rotating shaft Z, and the driving assembly 24 directly drives the roller screen 23 to rotate around the rotating shaft Z; or the roller screen 23 is fixedly connected with a rotating shaft Z, the rotating shaft Z can rotate relative to the support, and the driving assembly 24 indirectly drives the roller screen 23 to rotate by driving the rotating shaft Z to rotate.
In the above driving scheme, since the rotating shaft Z passes through the enclosing region, the effective capacity of the roller screen 23 can be reduced, and the collision probability between the electroplating material 101 and the rotating shaft Z may be increased in the production process, thereby causing yield loss. Referring to fig. 1, 2 and 4, fig. 4 isbase:Sub>A schematic cross-sectional view taken along linebase:Sub>A-base:Sub>A of fig. 2. The support 22 includes a first riser 221 and a second riser 222, the first riser 221 and the second riser 222 being disposed opposite one another, and the roller screen 23 being located between the first riser 221 and the second riser 222. Wherein, a first enclosing plate 231 of the roller screen 23 is connected with a first vertical plate 221 through a first connecting shaft 31, and a second enclosing plate 232 of the roller screen 23 is connected with a second vertical plate 222 through a second connecting shaft 32; the drive assembly 24 rotates the roller screen 23 relative to the frame 22 by driving the first 231 or second 232 closure.

One end of the first connecting shaft 31 is rotatably connected with the first enclosing plate 231 through a bearing, the other end of the first connecting shaft is fixedly connected with the first vertical plate 221, one end of the second connecting shaft 32 is rotatably connected with the second enclosing plate 232 through a bearing, and the other end of the second connecting shaft is fixedly connected with the second vertical plate 222. The end face of the first enclosing plate 231 or the end face of the second enclosing plate 232 is provided with a gear structure; the drive assembly 24 includes a drive motor 241 and a drive gear 242, the drive gear 242 being coupled to the drive motor 241 and being in meshing engagement with the gear structure.
It should be understood that in the above embodiment, the first connecting shaft 31 may also have one end fixedly connected to the first enclosing plate 231 and the other end rotatably connected to the first vertical plate 221 through a bearing, and similarly, the second connecting shaft 32 may also have one end fixedly connected to the second enclosing plate 232 and the other end rotatably connected to the second vertical plate 222 through a bearing, so that the driving assembly 24 can also drive the first enclosing plate 231 or the second enclosing plate 232 to rotate the roller screen 23 relative to the bracket 22.
In one embodiment, with continued reference to fig. 1, 2, and 4, the support frame 22 further includes a first beam 223, a second beam 224, and a third beam 225. First beam 223, second beam 224, and third beam 225 are each connected between first riser 221 and second riser 222. The first cross beam 223 and the second cross beam 224 are located below the roller screen 23, the third cross beam 225 is located above the roller screen 23, and the first cross beam 223, the second cross beam 224 and the third cross beam 225 are not located on the same vertical plane, so that the first vertical plate 221 and the second vertical plate 222 can be connected and fixed in a three-point (triangular) mode, and the overall stability of the support 22 is improved. As an example, the first beam 223 and the second beam 224 are located on the same horizontal plane, and a projection of the third beam 225 on the horizontal plane is located right in the middle between the first beam 223 and the second beam 224, so as to form a substantially symmetrical structure.

In order to reduce the precision of the rotation of the material inlet 21 to the target position in the material feeding station, the included angle between the connecting part of the handle 43 and the material feeding barrel 40 is adjustable. It should be noted that the handle in fig. 6 is two independent support rods, and a connecting rod may be used to connect the ends of the two independent support rods far from the charging barrel 40, so that the handle 43 is a U-shaped integral structure.
