Description

Sorting Device for Multi-layer Ceramic Capacitor chip

The present invention relates to a chip sorting apparatus for a multilayer ceramic capacitor capable of separating and classifying abrasive balls from a multilayer ceramic capacitor (MLCC) chip that has undergone a cleaning process.

In general, there are many types of capacitors used in various electronic and electrical devices, and they are being miniaturized with the advancement of technology.

Among capacitors, a multi-layer ceramic capacitor (hereinafter referred to as 'MLCC') is a component that measures electric charge according to the thickness of a dielectric material and an electrode area by applying a voltage, and its size is the size of a grain of rice. It is manufactured very small, ranging from several tens to several hundredths.

During the manufacturing process, MLCC chips are mixed with ceramic polishing balls with an average size of about 1 mm to 3 mm for the purpose of cleaning MLCCs. After inspecting the MLCC for defects, it is shipped as a product.

However, the size of these MLCC chips is about 0.2mm in length and 0.4mm in width, and the grinding balls are very small, about 1mm to 3mm in size. Sorting and separating is a very difficult task.

In addition, the sorting and sorting of the MLCC and the grinding balls requires a significant amount of time and is inefficient if handled by manpower.

Therefore, in consideration of this point, attempts to automatically sort MLCC and abrasive balls by an automated sorting machine are continuing.

In addition, if moisture is contained in the MLCC and the polishing ball, there is a phenomenon in which they stick to each other, and in this case, there is a problem in that it is not easy to sort the MLCC and the polishing ball.

In addition, the size of the MLCC chip may change according to technology development, and the size change may be in the order of hundreds of micrometers. is unable to respond.

The shaft 100 may pass through the movable block 96 and both ends may be fixed to the first fixing block 98 and the second fixing block 99 .

As shown in FIG. 20 , the compression spring 102 may be fitted on the outer periphery of the shaft 100 and disposed between the movable block 96 and the first fixed block 98 . As a result, the compression spring 102 exerts a restoring force in the direction of pushing the movable block 96 .

18 and 19 , a cam follower 108 is installed in front of the base plate 92 .

A bracket 112 may be installed on the device frame 130 , and a cam motor 120 may be installed on the bracket 112 .

The cam 110 may be installed on the motor shaft of the cam motor 120 to rotate, and may come into contact with the cam follower 108 to push or release the cam follower 108 .

Therefore, in the chip sorting device for multilayer ceramic capacitors according to the embodiment of the present invention, when the cam 110 is rotated, for example, when the cam 110 is rotated in the rotation direction, the compression spring ( The base plate 92 is pushed out by the restoring force of 102 .

Conversely, when the cam follower 108 moves from the valley to the mountain, the compression spring 102 is compressed while pushing the base plate 92 in.

That is, when the cam 110 rotates, the cam follower 108 may reciprocate while acting as a cam, and as the reciprocating motion proceeds quickly, the reciprocating motion may be developed into a vibrational motion. The oscillating motion may allow the MLCC chip 1 and the abrasive ball 2 to be more separated, and further accelerate the flow of the MLCC chip 1 .

On the other hand, as shown in FIG. 21 , the cam 110 has a first rotation angle (a) when going from the mountain to the valley based on the direction in which the cam 110 rotates from the valley to the mountain. It can be formed to be smaller than the second rotation angle (b), whereby the first time when the compression spring 102 is relaxed is formed shorter than the second time when the compression spring 102 is compressed.

That is, when the cam follower 108 moves from the mountain to the valley of the cam 110 , it may move rapidly as much as the mountain height h and collide with the cam 110 .

That is, in the chip sorting device for multilayer ceramic capacitors according to the embodiment of the present invention, when the base plate 92 is shaken, it can be shaken like a bouncing, and in particular, the cam follower 108 moves from the mountain to the valley of the cam 110 . When the expansion speed of the compression spring 102 is implemented quickly, a unique action effect that can vibrate like a tapping, rather than simply shaking, can be expected. 2) can contribute to more reliably separating the MLCC chip (1) and the movement of the abrasive ball (2) can be implemented more actively.

On the other hand, as shown in FIG. 17 , the control unit 132 and the display 140 may be provided on one side of the device frame 130 .
