Description

Technical Field

[0001] This utility model relates to the field of vacuum heating and sealing technology for material bags, and specifically to a high vacuum pressure heating mechanism. Background Technology

[0002] Ceramic capacitors are a general term for capacitors that use ceramic materials as the dielectric. Multilayer ceramic capacitors (MLCCs), also known as chip capacitors, multilayer capacitors, or stacked capacitors, are a type of ceramic capacitor. Multilayer ceramic capacitors (MLCCs) are characterized by their small size, large capacitance, low loss rate at high frequencies, suitability for mass production, low price, and high stability.

[0003] The internal electrode fabrication of multilayer ceramic capacitors (MLCCs) utilizes the principle of screen printing. Internal electrode patterns of a specific shape and size are printed onto a cast dielectric ceramic film. These patterns are then formed using a staggered, stacked method to create the internal electrode structure, resulting in a wafer. After isostatic pressing (under specific temperature and pressure), the bonding between the wafer layers is further strengthened. The laminated wafer is then trimmed and glued, and cut into capacitor chip blanks of the designed dimensions using a cutting technique. The capacitor chip blanks undergo glue removal and high-temperature sintering to transform the blank into a ceramic body, allowing the ceramic dielectric and internal electrodes to sinter into a dense monolithic entity.

[0004] Typically, the bar block is first placed into a laminated bag, then the laminated bag is sealed using a sealing device, and finally placed into a warm isostatic press. The warm isostatic press uses water or oil as a medium to apply pressure evenly to the laminated bag from all directions, making the bond between the bar block layers tighter and more solid. For example, the utility model patent with authorization announcement number CN207902853U discloses a packaging bag sealing device, including a base, a lower pressing block, guide pillars, a lifting plate, a fixing plate, a cylinder, a heating block, a heating device, a pressing head, and a silicone gasket. The base is provided with a lower pressing block, the top of which has a groove, and the groove contains a silicone gasket. Guide pillars are provided on both sides of the lower pressing block, the top of which has a fixing plate. A cylinder is provided on the fixing plate, and a lifting plate is provided below the fixing plate. The guide pillars all penetrate the lifting plate, and the power rod of the cylinder is connected to the lifting plate. The lower surface of the lifting plate is connected to a heating block through the fixing block. A heating device is provided inside the heating block, and a thermistor is also provided on the heating block. A pressing head is provided at the bottom of the heating block, and the pressing head cooperates with the silicone gasket. A tear-cutting device is also provided on the lifting plate.

[0005] Traditional laminar bag sealing methods involve placing the bag containing the sealing block into a sealing device, with the bag opening positioned between the heating block and the pressure block. The heating block and pressure block then clamp the bag opening, sealing it through heat pressing. However, this leaves a significant amount of air inside the laminar bag after sealing, reducing the tightness of the sealing block during the isostatic pressing process. Therefore, there is an urgent need in this technical field for a high-vacuum pressure heating mechanism to remove the air from the laminar bag before sealing the opening. Utility Model Content

Detailed Implementation

[0026] This utility model provides a high-vacuum pressure heating mechanism to address the shortcomings described in the background art, namely, that after a laminated bag containing a sealing block is sealed by a traditional sealing device, a significant amount of air remains in the laminated bag. The overall concept of the technical solution adopted by this utility model is as follows: A drawer-type heating and sealing assembly is installed in the vacuum chamber. The tray of the drawer-type heating and sealing assembly is used to place the laminated bag. First, the tray is pulled out. During the placement of the laminated bag, the bag contacts the limiting block, thus positioning the bag opening in the heating and sealing gap. Then, the tray is pushed in. At this time, the pressure plate and sealing block are positioned above the bag opening, and the lifting plate and heating element are positioned below the bag opening. The vacuum chamber is evacuated, causing the air in the laminated bag to leave from the bag opening and be removed. Then, the first and second synchronous telescopic cylinders of the pressure-lifting drive assembly are activated. The first synchronous telescopic cylinder... The piston rod extends and, via the downward drive rod, moves the downward pressure plate, the first vertical moving plate, and the downward support plate downwards. The sealing block presses down on the opening of the laminated bag. The piston rod of the second synchronous telescopic cylinder extends and, via the reversing plate and the upward drive rod, moves the second vertical moving plate and the upward support plate upwards. The heating element presses upwards against the opening of the laminated bag, sealing the opening of the laminated bag through heat-pressing fusion. Then, the vacuum chamber is broken, and the piston rods of both the first and second synchronous telescopic cylinders retract. The sealing block and the heating element simultaneously detach from the laminated bag. Finally, the tray is pulled out, and the sealed laminated bag is removed.
