[0026] Please refer to Figs. 1-3 A ceramic substrate high-efficiency sintering device, comprising a first support plate 1 and a second support plate 2, the first support plate 1 and the second support plate 2 are both arranged in a U shape, and the two ends of the second support plate 2 are respectively connected to the two ends of the first support plate 1 in a sliding manner, at least one first support platform 11 is fixedly arranged on the first support plate 1, and a second support platform 21 corresponding to the first support platform 11 is fixedly arranged on the second support plate 2, and a placing cavity is formed between the first support platform 11 and the second support platform 21; a locking assembly 4 is arranged between the first support plate 1 and the second support plate 2.

[0027] Further, the locking assembly 4 comprises an eccentric wheel 41 rotatably arranged at the end of the first support plate 1, a pull rod 42 is fixedly arranged on the eccentric wheel 41, and the pull rod 42 is arranged in the radial direction of the eccentric wheel 41. Rotating the pull rod 42 drives the eccentric wheel 41 to rotate, so that the eccentric wheel 41 abuts against the second support plate 2, and the second support plate 2 is fixed to the first support plate 1 through the friction between the second support plate 2 and the first support plate 1.

[0028] Further, the first support plate 1 and the second support plate 2 enclose a hot flow cavity 3, which facilitates the flow of heat in the sintering furnace.

[0029] Further, the first support platform 11 and the second support platform 21 are both arranged in an L shape.

[0030] Further, the bottom of the first support platform 11 and the second support platform 21 is respectively fixedly provided with a plurality of first arc-shaped blocks 12 and second arc-shaped blocks. The two sides of the substrate are respectively placed on the first arc-shaped blocks 12 and the second arc-shaped blocks, the gap between the first arc-shaped blocks 12 and the second arc-shaped blocks facilitates the passage of hot air, and the arc-shaped arrangement reduces the contact area with the substrate, thereby improving the sintering effect.

[0032] The first groove 14 on another first support table 11 is inserted into the first protrusion 13 on the first support table 11, and the second support table 21 is the same, so that multiple substrates are arranged in the vertical direction. In addition, multiple devices are arranged in the vertical direction, and each does not need to lock the first support plate 1 and the second support plate 2 by the locking assembly 4 (after the device is locked, the locking of the same device in the vertical direction is realized through the cooperation of the first protrusion 13 and the first groove 14), which simplifies the operation.

[0033] Working principle: the first groove 14 on another first support table 11 is inserted into the first protrusion 13 on the first support table 11, and the second support table 21 is the same, so that multiple substrates are arranged in the vertical direction. By moving the first support plate 1 and the second support plate 2 that slide relative to each other, substrates of different sizes can be supported, and the relative position of the first support plate 1 and the second support plate 2 is locked by the locking assembly 4, thereby reducing the height of the device and effectively increasing the number of substrates in the vertical direction of the sintering furnace.
