Such a loading structure has the following defects when used: due to the roughness of the surface of the ceramic substrate material, the vacuum suction cup cannot fit with the surface of the ceramic substrate material, which leads to insufficient adsorption force, thereby causing the ceramic substrate material to fall in the air, which not only causes damage to the ceramic substrate material, but also reduces the loading efficiency of the sintering furnace; for this reason, the present invention provides a loading structure for a ceramic substrate sintering furnace. Summary of the invention

[0009] A further technical improvement of the present invention is that a horizontal bar is slidably arranged on the strip plate in the vertical direction, a trapezoidal block is fixedly connected to the bottom of the horizontal bar, and the gear stops rotating when the horizontal bar moves down until the block is placed between two adjacent gear teeth on the gear.

[0010] A further technical improvement of the present invention is that a slide groove is vertically arranged on the strip plate, a slider is slidably arranged in the slide groove, and one side of the slider is fixedly connected to the horizontal bar.

DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0024] See also Figure 1-Figure 4 As shown, a feeding structure for a ceramic substrate sintering furnace comprises a sintering furnace body 1 and a placing table 2 for ceramic substrate materials arranged on one side of the sintering furnace body 1, a feeding piece is arranged above the sintering furnace body 1, and the feeding piece comprises an inverted U-shaped frame 3, a fixing block 4 is slidably arranged on the lower side of the top of the U-shaped frame 3, an electric cylinder 5 is vertically arranged at the bottom of the fixing block 4, a mounting plate 6 is horizontally arranged at the end of the output shaft of the electric cylinder 5, a vacuum suction cup 7 is horizontally arranged at the bottom of the mounting plate 6, and two No. 1 rods 8 are symmetrically rotated on the left and right sides of the electric cylinder 5, and a supporting plate 9 is fixedly connected to the bottom end of each No. 1 rod 8;

[0025] In the above, the sintering furnace body 1 is used to realize the sintering of the ceramic substrate material. The sintering furnace body 1 itself has a transportation network. When the ceramic substrate material is moved from the placing table 2 to the sintering furnace body 1 by the loading structure, the transportation network inside the sintering furnace body 1 is started, driving the ceramic substrate material into the interior of the sintering furnace body 1 for sintering; the specific loading process is: first, the fixing block 4 is moved to the top of the placing table 2, the vacuum suction cup 7 is first aligned with the ceramic substrate material, and then the electric cylinder 5 is started, so that the electric cylinder 5 drives the mounting plate 6 and the vacuum suction cup 7 to move downward, so that the vacuum suction cup 7 is tightly attached to the ceramic substrate material. The top of the ceramic substrate material, and then the vacuum pump connected to the vacuum suction cup 7 is started, so that the vacuum suction cup 7 begins to absorb the ceramic substrate material, and cooperates with the electric cylinder 5 to drive the mounting plate 6 to move upward, so that the ceramic substrate material leaves the top of the placing table 2. When the ceramic substrate material rises to mid-air, by driving the two No. 1 rods 8 to rotate toward the mounting plate 6, the two support plates 9 are located at the bottom of the ceramic substrate material, thereby supporting the ceramic substrate material, thereby avoiding the phenomenon that the ceramic substrate material falls in the air due to insufficient adsorption force of the vacuum suction cup 7, thereby ensuring the feeding efficiency of the sintering furnace.

[0026] Furthermore, racks 10 are fixed to the top of the mounting plate 6, and the two racks 10 are symmetrically arranged on the left and right sides of the electric cylinder 5. Gears 11 are distributed on the left and right sides of the electric cylinder 5, and the gears 11 are in meshing state with the racks 10. The top of the No. 1 rod 8 is fixedly connected to the shaft of the gear 11. When the vacuum suction cup 7 has adsorbed the ceramic substrate material and started to move upward, the minimum distance between the two support plates 9 is still greater than the length of the mounting plate 6, and when the bottom of the ceramic substrate material is higher than the bottom of the support plate 9, the rack 10 starts to mesh with the gear 11, so that the gear 11 on the left side of the electric cylinder 5 rotates counterclockwise at this time, and the gear 11 on the right side of the electric cylinder 5 rotates clockwise, so that the tops of the two support plates 9 are in contact with the bottom of the ceramic substrate material, so as to support the ceramic substrate material and avoid the phenomenon that the ceramic substrate material falls in the air due to insufficient adsorption force of the vacuum suction cup 7, thereby ensuring the feeding efficiency of the sintering furnace.

[0027] In the above, strip plates 12 are fixed on the left and right sides of the bottom of the fixed block 4 respectively, and the two strip plates 12 are symmetrically arranged on the left and right sides of the electric cylinder 5. The gear 11 is rotatably arranged on the strip plates 12 through a pin shaft; the gear 11 is rotatably arranged on the strip plates 12 through a pin shaft, so that the gear 11 produces stable rotation.

[0028] Furthermore, since the No. 1 rod 8 and the support plate 9 are provided on the shaft of the gear 11, there is a tendency to drive the shaft of the gear 11 to rotate downward. In order to avoid interference with the vacuum suction cup 7 after the No. 1 rod 8 and the support plate 9 rotate downward, the following structure is provided: a horizontal bar 15 is slidably provided on the strip plate 12 in the vertical direction, and a trapezoidal block 16 is fixedly connected to the bottom of the horizontal bar 15. When the horizontal bar 15 moves down and the block is placed between two adjacent gear teeth on the gear 11, the gear 11 stops rotating; when the electric cylinder 5 drives the mounting plate 6 to move downward, the trapezoidal block 16 is placed between two adjacent gear teeth on the gear 11, and at the same time the horizontal bar 15 is arranged horizontally, which can prevent the shaft of the gear 11 from rotating.

[0029] Furthermore, in order to improve the sliding stability of the horizontal bar 15 and prevent the horizontal bar 15 from flipping over, a slide groove 13 is vertically arranged on the strip plate 12, and a slider 14 is slidably arranged in the slide groove 13, and one side of the slider 14 is fixedly connected to the horizontal bar 15; through the cooperation between the slider 14 and the slide groove 13, the horizontal bar 15 can only slide in the vertical direction on the bar, and when the electric cylinder 5 drives the mounting plate 6 to move downward, the trapezoidal block 16 is placed between two adjacent gear teeth on the gear 11, thereby limiting the rotation of the gear 11 shaft.

[0030] In order to avoid the problem that the gear 11 cannot rotate due to the trapezoidal block 16 still being between two adjacent gear teeth on the gear 11 when the rack 10 just contacts the gear 11, the following structure is provided: a light rod 17 is fixedly connected to the top of the rack 10, and the length of the light rod 17 is greater than the radius of the tooth top circle; when the electric cylinder 5 drives the mounting plate 6 to move upward, the top end of the light rod 17 will contact the cross bar 15, and the trapezoidal block 16 will leave from between two adjacent gear teeth through the upward displacement of the light rod 17, and then when the rack 10 contacts the gear 11, the gear 11 can rotate normally, ensuring that the two support plates 9 can be located at the bottom of the ceramic substrate material.

[0031] In order to prevent the horizontal bar 15 from staying at a certain height after the light rod 17 pushes the horizontal bar 15 up, resulting in the horizontal bar 15 being unable to move downward to between two adjacent gear teeth of the trapezoidal block 16, the following structure is provided: a magnet sheet 18 is fixedly connected to the top of the light rod 17, and a magnet sheet 18 is also fixedly connected to the bottom of the horizontal bar 15, and the two magnet sheets 18 have opposite magnetic properties on the sides facing each other; when the magnet sheet 18 at the top of the light rod 17 is adsorbed with the magnet sheet 18 at the bottom of the horizontal bar 15, the light rod 17 is always connected to the horizontal bar 15 when it moves upward and downward, thereby ensuring that the horizontal bar 15 can move downward, and at the same time, when the trapezoidal block 16 is between two adjacent gear teeth, the light rod 17 can continue to move downward, so that the two magnet sheets 18 are separated.

[0032] A motor 19 is fixedly provided on the outer side wall of the U-shaped frame 3, a guide rod 21 is fixedly provided on the lower side of the top of the U-shaped frame 3 and a threaded rod 20 is rotatably provided, and the guide rod 21 and the threaded rod 20 are both arranged horizontally and parallel to each other, and one end of the threaded rod 20 is connected to the output shaft of the motor 19; the guide rod 21 and the threaded rod 20 respectively penetrate the fixed block 4; when working, the threaded rod 20 is driven to rotate by the motor 19, so that the threaded rod 20 drives the fixed block 4 to move horizontally under the U-shaped frame 3, so as to realize the adsorption and placement of the ceramic substrate material, thereby realizing the loading of the sintering machine body.

[0033] When the present invention is in use, the motor 19 is first used to drive the threaded rod 20 to rotate, so that the threaded rod 20 drives the fixing block 4 to move horizontally below the U-shaped frame 3. When the fixing block 4 moves to the top of the placing table 2, the vacuum suction cup 7 is first aligned with the ceramic substrate material, and then the electric cylinder 5 is started, so that the electric cylinder 5 drives the mounting plate 6 and the vacuum suction cup 7 to move downward, so that the vacuum suction cup 7 is closely attached to the top of the ceramic substrate material. After that, the vacuum pump connected to the vacuum suction cup 7 is started, so that the vacuum suction cup 7 starts to absorb the ceramic substrate material, and cooperates with the electric cylinder 5 to drive the mounting plate 6 to move upward, so that the ceramic substrate material leaves the top of the placing table 2. When the vacuum suction cup 7 has absorbed the ceramic substrate material, the vacuum suction cup 7 is pressed against the ceramic substrate material. When the material is loaded and starts to move upward, the minimum distance between the two support plates 9 is still greater than the length of the mounting plate 6, and when the bottom of the ceramic substrate material is higher than the bottom of the support plate 9, the rack 10 starts to mesh with the gear 11, so that the gear 11 on the left side of the electric cylinder 5 rotates counterclockwise at this time, and the gear 11 on the right side of the electric cylinder 5 rotates clockwise, so that the tops of the two support plates 9 are in contact with the bottom of the ceramic substrate material, so that the two support plates 9 are located at the bottom of the ceramic substrate material, supporting the ceramic substrate material, thereby avoiding the phenomenon that the ceramic substrate material falls in the air due to insufficient adsorption force of the vacuum suction cup 7, and ensuring the feeding efficiency of the sintering furnace.

[0034] When the electric cylinder 5 drives the mounting plate 6 to move upward, the magnet sheet 18 at the top of the light rod 17 is adsorbed together with the magnet sheet 18 at the bottom of the horizontal bar 15. Through the upward displacement of the light rod 17, the trapezoidal block 16 is separated from between two adjacent gear teeth. Then, when the rack 10 contacts the gear 11, the gear 11 can rotate normally, ensuring that the two support plates 9 can be located at the bottom of the ceramic substrate material; and when the magnet sheet 18 at the top of the light rod 17 is adsorbed together with the magnet sheet 18 at the bottom of the horizontal bar 15, the light rod 17 is always connected to the horizontal bar 15 when it moves upward and downward, ensuring that the horizontal bar 15 can move downward. At the same time, when the trapezoidal block 16 is between two adjacent gear teeth, the light rod 17 can continue to move downward, so that the two magnet sheets 18 are separated.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
