Description

Technical Field

[0001] This invention relates to the field of ceramic sintering technology, specifically to a ceramic substrate sintering furnace. Background Technology

[0002] Ceramic substrates refer to special process boards in which copper foil is directly bonded to the surface of alumina or aluminum nitride ceramic substrates at high temperatures. The resulting ultra-thin composite substrates have excellent electrical insulation properties, high thermal conductivity, excellent solderability and high adhesion strength. They can also be etched with various patterns like PCB boards and have a large current carrying capacity. Therefore, ceramic substrates have become the basic material for high-power power electronic circuit structure technology and interconnection technology.

[0003] Currently, uneven heating is a common problem in ceramic sintering. Traditionally, the ceramic substrate is placed directly into a sintering furnace, requiring manual adjustment by the user. This manual adjustment is prone to subjective errors, leading to uneven sintering. Therefore, we propose a ceramic substrate sintering furnace. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a ceramic substrate sintering furnace, which has the advantages of uniformly firing the ceramic substrate and solves the problem of uneven firing of ceramic substrates in existing technologies.

[0015] Compared with the prior art, the present invention provides a ceramic substrate sintering furnace, which has the following beneficial effects:

[0016] 1. This ceramic substrate sintering furnace, through the protective shell, allows the motor installed inside the protective shell to rotate. After the user opens the motor, the motor drives the rolling gear fixedly sleeved at the top of its output shaft to rotate. After the rolling gear rotates, the transmission gear that is in contact with its side and whose structure is mutually matched rotates. After the transmission gear rotates, the protective shaft connected to the transmission gear rotates. Finally, the user can adjust the angle of the ceramic substrate placed on the operating plate.

An indicator light 5 is welded to the front surface of the ceramic sintering furnace body 1. A heating chamber assembly 10 and a pressure chamber assembly 11 are installed inside the ceramic sintering furnace body 1. (The heating chamber assembly 10 and the pressure chamber assembly 11 are inherent structures of existing ceramic sintering furnaces and are known technologies, and will not be discussed further here.) (Detailed description) A handle 8 is fixedly connected to the front surface of the sealed protective door 7. A controller 4 is welded to the front surface of the ceramic sintering furnace body 1. A transmission mechanism 9 is installed on the inner ring surface of the ceramic sintering furnace body 1. An adjustment mechanism 3 is installed on the upper surface of the transmission mechanism 9. The transmission mechanism 9 includes a power output device and a transmission device. The power output device can convert the output power into rotational force, and the transmission device can transmit the power to the fired ceramic substrate, so that the angle of the ceramic substrate can be adjusted.

[0026] In this embodiment, the power output device includes a mounting block 903. A protective shell 901 is fixedly connected to the side surface of the mounting block 903. A motor 904 is fixedly connected to the inner ring surface of the protective shell 901. A rolling gear 905 is fixedly sleeved on the top end of the output shaft of the motor 904. The angle of the transmission gear 906 can be adjusted by the rolling gear 905 fixedly sleeved on the top end of the output shaft of the motor 904.

[0027] Furthermore, the transmission device includes a gripping rod 911, a protective shaft 907 is fixedly connected to the side surface of the gripping rod 911, a limiting support rod 909 is fixedly connected to the inner surface of the protective shaft 907, a transmission gear 906 is fixedly connected to the outer surface of the protective shaft 907, and a limiting plate 910 is fixedly connected to the bottom surface of the limiting support rod 909. The limiting plate 910 fixedly connected to the bottom surface of the limiting support rod 909 can limit the movement of the limiting support rod 909.

[0028] Furthermore, the bottom surface of the protective shell 901 is provided with heat dissipation openings 902, and there are multiple heat dissipation openings 902. By providing multiple heat dissipation openings 902, users can easily dissipate heat inside the protective shell 901.

[0029] In addition, the inner ring surface of the protective shaft 907 is provided with a plug-in opening 908, and the plug-in opening 908 and the limiting support rod 909 are structurally compatible. Through the plug-in opening 908, which is structurally compatible with the limiting support rod 909, the limiting support rod 909 can be limited during movement.

[0030] In addition, it also includes an adjustment mechanism 3, which includes a mounting base plate 301, a first telescopic rod 302, a limiting rod 303, a pushing plate 304, a placement operation plate 305, and a support plate 306. The support plate 306 is fixedly connected to the inner ring surface of the ceramic sintering furnace body 1. The mounting base plate 301 is movably connected to the upper surface of the support plate 306. The first telescopic rod 302 is fixedly connected to the mounting base plate 301. The pushing plate 304 is fixedly connected to the upper surface of the first telescopic rod 302. The limiting rod 303 is fixedly connected to the upper surface of the mounting base plate 301. The limiting rod 303 is movably engaged on the side surface of the limiting rod 303. The placement operation plate 305 is movably connected to the upper surface of the limiting rod 303. The placement operation plate 305, which is movably connected to the upper surface of the limiting rod 303, facilitates the user in placing the ceramic substrate to be sintered.

[0031] It is worth noting that the bottom surface of the ceramic sintering furnace body 1 is fitted with anti-slip fixing feet 2, and there are multiple anti-slip fixing feet 2 that are parallel to each other. The multiple anti-slip fixing feet 2 that are parallel to each other make it easy for users to place the ceramic sintering furnace body 1 stably.

[0032] In use, the protective housing 901 is installed, and after the user opens the motor 904 installed inside the protective housing 901, the motor 904 can drive the rolling gear 905, which is fixedly sleeved at the top of its output shaft, to rotate. After the rolling gear 905 rotates, it can rotate the transmission gear 906, which is in side contact with the transmission gear 906 and whose structure is mutually engaged. After the transmission gear 906 rotates, the protective shaft 907 connected to the transmission gear 906 can rotate. Finally, the user can adjust the angle of the ceramic substrate placed on the operating panel 305. After opening the heating chamber assembly 1... After the 0 and pressurization chamber assembly 11 are installed, the user can pressurize and fire the ceramic substrate placed on the storage operation panel 305. By rotating the ceramic substrate, the heat of the ceramic substrate can be uniformly fired. By setting the first telescopic rod 302, after the user starts the first telescopic rod 302, the push plate 304 fixedly connected to the output end of the first telescopic rod 302 can be pushed, thus pushing the storage operation panel 305. By limiting the storage operation panel 305 with the limit rod 303, the user can adjust the angle of the ceramic substrate placed on the storage operation panel 305.
