Description

Technical Field

[0001] This utility model relates to the field of multilayer ceramic capacitor technology, specifically to an MLCC dip-plating implantation device. Background Technology

[0002] MLCC (Multilayer Ceramic Capacitor) mainly consists of three parts: external electrode, internal electrode, and dielectric layer (ceramic body). Its main processes include ball milling, slurry preparation, tape making, printing, stacking, pressing, cutting, organic material firing, high-temperature sintering, rolling, dip plating, sintering, electroplating, testing, and packaging.

[0003] The dip-plating process mainly involves dipping the end paste onto the two ends of the exposed internal electrodes of the capacitor after it has been tumbled and ground, connecting the internal electrodes on the same side to form the external electrodes. The process flow includes applying adhesive, implantation, dip-plating the first side, baking, flipping, dip-plating the second side, baking, and collecting the material. The traditional implantation process mainly uses vibration to implant the MLCC product into the hole of the jig plate with single-sided tape applied while vibrating. The jig plate is used to support the MLCC product and expose the product end to facilitate the dip-plating of metal paste. However, this implantation method is not suitable for MLCC products of different lengths, and errors caused by human intervention during implantation can easily affect the product yield. Therefore, an MLCC dip-plating implantation device is proposed to solve the above problems. Utility Model Content

[0017] 1. The distance between the JIG base plate and the JIG movable plate can be adjusted by setting an adjusting screw, which facilitates the implantation of MLCCs of different lengths.

[0018] 2. By setting a guide mesh on the JIG movable plate, the edges between the meshes on the guide mesh are all arc-shaped, which facilitates the MLCC falling into the mesh holes between the guide meshes.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.

[0032] Please see Figures 1-5 This utility model proposes an MLCC dip-plating implantation device. In use, firstly, according to the length of the MLCC to be dipped, the distance between the JIG base plate 10 and the JIG movable plate 20 is adjusted by adjusting the lead screw 15. The lead screw 15 is movably installed in the middle position on both sides of the JIG base plate 10. The JIG movable plate 20 is located above the JIG base plate 10. A second connecting block 23 is fixedly installed in the middle position on both sides of the JIG movable plate 20. The second connecting block 23 is threadedly connected to the lead screw 15. A knob is provided above the lead screw 15. When the lead screw 15 is rotated by the knob, the rotation of the lead screw 15 will drive the second connecting block 23 to move up and down, thereby causing the JIG movable plate 20 to move up and down above the JIG base plate 10, thereby changing the distance between the JIG base plate 10 and the JIG movable plate 20, which facilitates dip-plating of MLCCs of different lengths.

[0033] When the distance between the JIG base plate 10 and the JIG movable plate 20 is adjusted by adjusting the lead screw 15, a limiting rod 14 is fixedly installed at each of the four corners of the JIG base plate 10, and a first connecting block 21 is fixedly installed at each of the four corners of the JIG movable plate 20. The first connecting block 21 is movably connected to the limiting rod 14. The limiting rod 14 has a limiting block at the top. When the adjusting lead screw 15 is rotated to move the JIG movable plate 20, the first connecting block 21 at the four corners of the JIG movable plate 20 will move up and down along the limiting rod 14. Thus, the limiting rod 14 can maintain the stability of the JIG movable plate 20 when it moves, making it convenient for the adjusting lead screw 15 to adjust the distance between the JIG base plate 10 and the JIG movable plate 20.

[0034] After adjusting the distance between the JIG base plate 10 and the JIG movable plate 20, align the guide mesh plate 24 with the limiting protrusions 22 fixedly installed on the first connecting blocks 21 at the four corners of the JIG movable plate 20. The limiting protrusions 22 fit with the four corners of the guide mesh plate 24. Install the guide mesh plate 24 above the JIG movable plate 20. At this time, throw the MLCC onto the guide mesh plate 24 and start the vibrating plate 12 below the JIG base plate 10. When the vibrating plate 12 works, it will drive the JIG base plate 10 and the JIG movable plate 20 to vibrate. At the same time, the JIG movable plate 20 will drive the guide mesh plate 24 on the JIG movable plate 20 to vibrate. When the guide mesh plate 24 vibrates, since the edges between the mesh plates on the guide mesh plate 24 are all arc-shaped, it is beneficial for the MLCC to fall into the mesh holes between the guide mesh plates 24. The JIG movable plate 20 has equal... The MLCCs are positioned so that the holes on the guide plate 24 correspond to the positions and sizes of the holes on the guide plate 24. The MLCCs fall into the holes on the JIG movable plate 20 through the holes on the guide plate 24. The four sides of the holes in the JIG movable plate 20 are arc-shaped, and the holes are wider at the top and narrower at the bottom. The MLCCs are easily positioned by the holes in the JIG movable plate 20 and fall into the limiting holes opened on the JIG base plate 10. The limiting holes opened on the JIG base plate 10 are square holes with equal spacing, which helps to limit the position of the MLCCs. This allows one end of the MLCC to contact the tape 11. The tape 11 is a single-sided tape with adhesive on the side closest to the JIG base plate 10. The tape 11 is used to stick the MLCCs implanted in the JIG base plate 10, which facilitates the implantation of the MLCCs.

[0035] Since the internal electrode material of MLCC is metal, the magnetic adsorption plate 13 increases magnetic adsorption on the basis of vibration, which is conducive to the MLCC being placed into the limiting hole on the JIG base plate 10, thereby increasing the implantation rate.

[0036] Positioning protrusions that match the shape and size of the tape 11 are designed on the bottom of the JIG base plate 10. When the tape 11 is attached to the bottom of the JIG base plate 10, the positioning protrusions can ensure that the tape 11 accurately covers the bottom of the limiting hole, preventing the tape 11 from shifting or wrinkling, and ensuring the effective adhesion and fixation of the tape 11 to the MLCC. At the same time, the depth and height of the positioning protrusions are adapted to the thickness of the tape 11, so that the surface of the tape 11 after attachment is flush with or slightly lower than the bottom surface of the JIG base plate 10, avoiding affecting the placement and movement of the JIG base plate 10 in the device.

[0037] The distance between the JIG base plate 10 and the JIG movable plate 20 is adjusted by setting the adjusting screw 15, which facilitates the implantation of MLCCs of different lengths. By setting a guide mesh plate 24 on the JIG movable plate 20, the edges between the mesh plates on the guide mesh plate 24 are all arc-shaped, which helps the MLCCs fall into the mesh holes between the guide mesh plates 24. The four sides of the through holes in the JIG movable plate 20 are arc-shaped, and the through holes in the JIG movable plate 20 are wider at the top and narrower at the bottom. Thus, the MLCCs are easily aligned by the through holes in the JIG movable plate 20 and fall into the limiting holes opened on the JIG base plate 10. The limiting holes opened on the JIG base plate 10 are square holes that are evenly distributed, which helps to limit the MLCCs and facilitates the limiting and implantation of MLCCs. This process can reduce human operation and intervention, thereby reducing implantation errors and improving the yield rate.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
