Chip capacitor high-temperature sintering furnace

Abstract

This utility model discloses a high-temperature sintering furnace for surface mount capacitors, including a sintering furnace that is electrically heated. A first mesh belt is installed in the middle of the sintering furnace. After the surface mount capacitors are sintered at high temperature through the operation of the sintering furnace, they are conveyed out from the discharge end of the sintering furnace. The ceramic tray containing the surface mount capacitors is conveyed to a second mesh belt on the discharge rack. The second mesh belt is driven by the operation of a drive component to transfer the ceramic tray containing the surface mount capacitors from the first mesh belt to the second mesh belt. There is no need for manual removal of the ceramic trays from the sintering furnace, which facilitates the unloading of surface mount capacitors from the sintering furnace. The operation of a fan can blow air to cool the surface mount capacitors on the second mesh belt, reducing the heat of the ceramic trays and making it easier for workers to remove the ceramic trays containing the surface mount capacitors.

Description

Technical Field

[0001] This utility model relates to the field of chip capacitor processing technology, specifically a high-temperature sintering furnace for chip capacitors. Background Technology

[0002] The manufacturing process of surface mount capacitors mainly includes material processing, molding, packaging and performance testing. Among them, high-temperature sintering of surface mount capacitors is the core manufacturing process of ceramic multilayer surface mount capacitors. During the sintering process, a sintering furnace is required to perform high-temperature sintering operations on the surface mount capacitors.

[0003] In existing sintering furnaces, ceramic trays containing surface-mount capacitors are placed on a mesh conveyor belt. The capacitors are then sintered by high-temperature heating inside the furnace. However, after sintering, the ceramic trays are still very hot, requiring workers to remove them from the conveyor belt by hand or with tools. This can easily cause hand injuries and poses a safety risk. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 3 As shown in this embodiment, a high-temperature sintering furnace for surface mount capacitors includes a sintering furnace 1, which is electrically heated. A first mesh belt conveyor 2 is installed in the middle of the sintering furnace 1. A discharge rack 3 is installed at the end of the sintering furnace 1 corresponding to the first mesh belt conveyor 2. A second mesh belt conveyor 4 is installed in the middle of the discharge rack 3. A drive assembly for driving the second mesh belt conveyor 4 is installed on the discharge rack 3. Fixing frames 5 are fixedly installed at equal intervals at the bottom of the discharge rack 3. A fan 6 is fixedly installed in the middle of the fixing frame 5. A ceramic tray containing surface mount capacitors is placed on the first mesh belt conveyor 2 at the feed end of the sintering furnace 1 and transported by the conveying assembly in the sintering furnace 1. The operation enables the first mesh belt conveyor 2 to transport the ceramic pallet to the middle of the sintering furnace 1. The sintering furnace 1 performs high-temperature sintering of the chip capacitors, and then the ceramic pallet containing the chip capacitors is transported from the discharge end of the sintering furnace 1 to the second mesh belt conveyor 4 on the discharge rack 3. The second mesh belt conveyor 4 is driven by the drive component to transfer the ceramic pallet containing the chip capacitors from the first mesh belt conveyor 2 to the second mesh belt conveyor 4. The operation of the fan 6 can blow air to cool the chip capacitors on the second mesh belt conveyor 4, reducing the heat of the ceramic pallet and making it easier for workers to remove the ceramic pallet containing the chip capacitors.

[0021] like Figures 1 to 3 As shown, the second mesh belt 4 is positioned lower than the first mesh belt 2.

[0022] This arrangement prevents the ceramic pallet from touching the end of the second mesh conveyor belt 4 and interfering with the transfer of the ceramic pallet.

[0023] like Figures 1 to 3 As shown, a mounting frame 7 is fixedly installed at the discharge end of the sintering furnace 1. Electric push rods 8 are fixedly installed at both ends of the mounting frame 7. The moving end of the electric push rod 8 passes through the mounting frame 7 and is fixedly installed with a push plate 9. The moving end of the electric push rod 8 is slidably connected to the mounting frame 7.

[0024] When the ceramic pallet passes the mounting frame 7, two electric push rods 8 control two push plates 9 to squeeze the ceramic pallet, which can ensure that the ceramic pallet is centered and vertically placed on the first mesh belt conveyor 2, and improve the stability of the ceramic pallet when it is transferred from the first mesh belt conveyor 2 to the second mesh belt conveyor 4.

[0025] like Figures 1 to 3 As shown, ball bearings 10 are equidistantly rolled inside one side of the push plate 9.

[0026] During the process of the push plate 9 pressing the ceramic pallet, the setting of the ball bearings 10 can control the ceramic pallet to move continuously along the surface of the push plate 9, preventing the ceramic pallet from moving relative to the first mesh belt conveyor belt 2.

[0027] like Figures 1 to 3 As shown, a vision camera 11 is fixedly mounted on the top lower surface of the mounting bracket 7, and a controller 12 is fixedly mounted on one side of the sintering furnace 1. The controller 12 is electrically connected to the vision camera 11.

[0028] The visual camera 11 can take pictures of the chip capacitors inside the ceramic tray and transmit the pictures to the controller 12. The controller 12 can detect the chip capacitors inside the ceramic tray.

[0029] like Figures 1 to 3 As shown, a temperature sensor 13 is fixedly installed on the top lower surface of the mounting bracket 7.

[0030] Temperature sensor 13 can monitor the temperature of the chip capacitors inside the ceramic tray to detect whether the chip capacitors have reached the heating requirements.

[0031] like Figures 1 to 3 As shown, servo motors 14 are fixedly installed on both sides of the discharge end of the sintering furnace 1, and pusher plates 15 are fixedly installed on the output end of the servo motors 14.

[0032] When the ceramic pallet is transferred from the end of the first mesh belt 2 to the second mesh belt 4, the position of the ceramic pallet can be determined by the controller 12 and the conveying speed of the first mesh belt 2 and the second mesh belt 4. Then, the pusher plate 15 is driven to rotate by the servo motor 14, which can push the ceramic pallet on the first mesh belt 2 to move the entire ceramic pallet onto the second mesh belt 4.

[0033] This utility model provides a high-temperature sintering furnace for surface mount capacitors, the specific working principle of which is as follows:

[0034] When the device is in use, a ceramic tray containing surface-mount capacitors is placed on the first mesh belt conveyor 2 at the feed end of the sintering furnace 1. The operation of the conveying components in the sintering furnace 1 operates the first mesh belt conveyor 2, transporting the ceramic tray to the middle of the sintering furnace 1. The operation of the sintering furnace 1 performs high-temperature sintering of the surface-mount capacitors, and then the ceramic tray containing surface-mount capacitors is transported from the discharge end of the sintering furnace 1 to the second mesh belt conveyor 4 on the discharge rack 3. The operation of the drive components drives the second mesh belt conveyor 4, transferring the ceramic tray containing surface-mount capacitors from the first mesh belt conveyor 2 to the second mesh belt conveyor 4. The operation of the fan 6 blows air to cool the surface-mount capacitors on the second mesh belt conveyor 4, reducing the heat of the ceramic tray and making it easier for workers to remove the ceramic tray containing surface-mount capacitors.

[0035] 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.
