TECHNICAL FIELD

[0001] The utility model relates to ceramic capacitor production technical field, specifically is ceramic capacitor sintering device. BACKGROUND

[0002] The chip type ceramic vacuum capacitor is formed by stacking ceramic dielectric film pieces with printed electrodes (internal electrodes) in a staggered manner, high-temperature sintering once to form a ceramic chip, and then sealing a metal layer (external electrode) on both ends of the chip, thereby forming a structure similar to a monolith. In actual production of chip type ceramic vacuum capacitors, a chip type ceramic vacuum capacitor sintering device is often used to complete the high-temperature sintering operation of the chip type ceramic vacuum capacitor. The actual use has the advantages of simple operation, high yield, and stable sintering.

[0003] After searching, the Chinese authorized publication No. CN214848236U discloses a chip type ceramic vacuum capacitor sintering device, which includes a housing, a fan fixedly installed on the inner top and bottom surfaces of the housing, two groups of electric heaters and two groups of guide rail plates fixedly installed in the housing, a clamping groove arranged on the opposite surfaces of the two groups of guide rail plates, a placing frame slidingly installed between the two groups of clamping grooves, a fixed filter screen fixedly installed in the placing frame, two groups of fixed rods fixedly installed on the upper part of the fixed filter screen, six groups of sleeve pipes and three groups of support filter screens sleeved and installed on the side walls of the two groups of fixed rods, and two groups of lifting groove plates placed and installed on the upper part of the fixed filter screen.

[0004] In the above-mentioned patent document, after sintering the capacitor, the door of the cabinet needs to be opened manually for unloading.

In addition, the placing rack after sintering also has high temperature, and additional tools are needed to take out the placing rack, which makes the loading and unloading more inconvenient. Therefore, we propose a ceramic capacitor sintering device to solve the existing problems. UTILITY MODEL CONTENTS

[0028] like Figures 1-5 As shown, this utility model is a ceramic capacitor sintering device, including a sintering box 1. Electric heating devices are installed on both the upper and lower sides of the interior of the sintering box 1. A control panel 2 is fixedly connected to the front side of the sintering box 1. A first air inlet pipe 3 is fixedly connected to one side of the sintering box 1. A second air inlet pipe 4 is fixedly connected to the other side of the sintering box 1. Flow meters 5 are installed on the outer sides of both the first air inlet pipe 3 and the second air inlet pipe 4. An exhaust port is provided on the rear side of the sintering box 1. A cabinet door 6 is provided on the outer side of the sintering box 1. An opening and closing assembly 7 is provided on the other side of the sintering box 1.

[0029] During operation, the cabinet door 6 can be opened or closed by a motor driven by the opening and closing component 7. The placement rack component 9 can be automatically pulled out for loading when the cabinet door 6 is open by the connecting rod 10 and connecting rod 21. When the cabinet door 6 is closed, the placement rack component 9 containing ceramic capacitors can be pushed into the sintering box 1 for easy loading and unloading by personnel. The ceramic capacitors are heated and sintered by the electric heating devices on the upper and lower sides of the sintering box 1.

[0030] like Figure 1 , Figure 3 and Figure 4As shown, the opening and closing assembly 7 includes a fixed plate 701, a drive motor 702, a screw 703, a movable block 704, a limiting groove 705, a connecting rod 706, a support plate 707, an extension plate 708, and a lifting lug 709. The fixed plate 701 is fixedly connected to both ends of the outer side of the sintering box 1. The drive motor 702 is fixedly connected to the outer side of the sintering box 1. One end of the screw 703 is fixedly connected to the output shaft of the drive motor 702. The movable block 704 is threadedly connected to the outer side of the screw 703. One side of the sintering box 1 is slidably connected to the inside of the limiting groove 705. The limiting groove 705 is opened on the outside of the sintering box 1. The connecting rod 706 is rotatably connected to both sides of the movable block 704. The other end of the connecting rod 706 is rotatably connected to the inside of the lifting lug 709. The support plate 707 is fixedly connected to the outside of the sintering box 1. One end of the extension plate 708 is rotatably connected to the inside of the support plate 707. The other end of the extension plate 708 is fixedly connected to the outside of the cabinet door 6. The lifting lug 709 is fixedly connected to the outside of the extension plate 708.

[0031] During operation, the drive motor 702 is started to rotate, which drives the screw 703 to rotate. With the guidance of the limit groove 705, the movable block 704 can be moved horizontally. At the same time, one end of the connecting rod 706 is moved horizontally, causing the other end of the connecting rod 706 to pull the lifting lug 709, which in turn causes the extension plate 708 to rotate on the support plate 707, thereby driving the cabinet door 6 to rotate and automatically opening or closing the cabinet door 6, reducing safety hazards.

[0032] like Figure 1 , Figure 4 and Figure 5 As shown, the placement rack assembly 9 includes a sliding plate 901, a limiting frame 902, a placement frame 903, a through hole 904, a support part 905, and a filter screen 906. The sliding plate 901 is slidably connected between two guide rails 8. The limiting frame 902 is fixedly connected to the top of the sliding plate 901. The placement frame 903 is placed inside the limiting frame 902. The through hole 904 is opened inside the placement frame 903 and the sliding plate 901. The support part 905 is fixedly connected to the inside of the placement frame 903. The filter screen 906 is placed on the top of the support part 905.

[0033] During operation, the placement frame 903 is removed from the limiting frame 902, and the filter screen 906 is removed at the same time. Then, the ceramic capacitor is placed at the bottom of the placement frame 903, and after the filter screen 906 is installed, the ceramic capacitor can be placed. After the placement is completed, the placement frame 903 is put back into the limiting frame 902 to complete the loading work.

[0034] Working principle: When sintering ceramic capacitors, the drive motor 702 is started first, which drives the screw 703 to rotate. This, combined with the guide of the limit groove 705, moves the movable block 704 horizontally. Simultaneously, one end of the connecting rod 706 moves horizontally, causing the other end of the connecting rod 706 to pull the lifting lug 709. This causes the extension plate 708 to rotate on the support plate 707, opening the cabinet door 6. Simultaneously, with the help of connecting rods 10 and 21, the placement rack assembly 9 can be pulled out. Then... The operator places the ceramic capacitor into the placement rack assembly 9, and drives the screw 703 to rotate in the opposite direction by starting the drive motor 702, which can close the cabinet door 6 again. At the same time, the placement rack assembly 9 containing the ceramic capacitor is pushed into the sintering box 1. The ceramic capacitor is heated and sintered by the electric heating devices on the upper and lower sides of the sintering box 1. In addition, nitrogen and oxygen can be introduced through the first air inlet pipe 3 and the second air inlet pipe 4 respectively to facilitate the sintering of the ceramic diaphragm. After sintering is completed, the cabinet door 6 is opened, and the placement rack assembly 9 can be automatically pulled to facilitate loading and unloading by personnel.

[0035] When loading materials, first remove the placement frame 903 from the limiting frame 902 and remove the filter screen 906 at the same time. Then, place the ceramic capacitor at the bottom of the placement frame 903, and then put the filter screen 906 in before placing more ceramic capacitors. After placing all the ceramic capacitors, put the placement frame 903 back into the limiting frame 902 to complete the loading process.
