Description

Technical Field

[0001] The utility model relates to the technical field of multilayer ceramic capacitor production, in particular to an anti-overlapping device suitable for an automatic bagging machine. Background Art

[0002] In the manufacturing process of multilayer ceramic capacitors (MLCC), the ceramic green blocks produced in the lamination workshop need to be hydrostatically pressed using a warm water isostatic press to form a whole with a flat outer surface, a compact inner structure, and an electrode layer and a dielectric layer that fits evenly and tightly. Before hydrostatic pressing, in order to prevent the product from being contaminated by the pressure medium of the hydrostatic press (usually emulsified water or emulsified oil), the blocks are put into bags of composite film through a bagging machine to protect the product. Because the blocks just produced in the lamination workshop are usually softer, during the automatic operation of the bagging machine, the blocks will generally overlap at different frequencies due to the existence of surface tension, that is, the robot should take a block from the material bin each time and place it at the bagging station. Due to surface tension problems, two or three pieces will overlap at the bagging station.

[0003] There are two ways to solve this problem in the industry: (1) Reduce the number of blocks in the block bin; reduce the gravity and then reduce the surface tension to reduce the overlap; this method is not only not practical, but also has no way to solve all specifications of blocks. For example, blocks with a thickness of less than 0.6MM are basically ineffective. However, due to the large number of product specifications and different formulas and processes, the thickness and hardness of the blocks vary greatly. It is difficult to accurately identify the number in actual operation. Even if the blocks are added to the bin according to the number, the actual production process only reduces the number of overlaps to a certain extent, and cannot completely prevent overlaps. (2) Improve the overlap by adjusting the suction of the manipulator suction cup or replacing different sizes of suction nozzles, that is, by reducing the deformation of the force-bearing part of the block. This method also has little effect on thinner blocks. However, this method is not only not easy to operate, but also cumbersome. In the actual production process, some batches of blocks cannot perfectly cooperate with the suction and suction cups, which will also cause the blocks to deform or even electrode offset. Utility Model Content

[0004] The utility model aims to provide a device for preventing bar overlap suitable for an automatic bagging machine, which can ensure that the robot suction cup of the automatic bagging machine only absorbs one bar block at a time, thereby efficiently and reliably solving the problem of bar overlap caused by the adhesion of bar blocks.
