[0028] The automatic placing device for firing high-purity alumina ceramic sheets of this embodiment is shown in FIG. Figure 1-Figure 3 The device can put high-purity alumina ceramic sheets into the sintering tray, place the sintering trays one by one on the roller conveyor, and stack multiple sintering trays through the coordinated cooperation of the roller conveyor, the lifting assembly, the guard assembly and the clamping assembly, and convey the high-purity alumina ceramic sheets in the sintering trays to the sintering furnace for sintering through the roller conveyor. The firing efficiency is high, the burden of manpower is reduced, and injuries to personnel are avoided. It mainly includes an operating table 1, a roller conveyor 2 is fixedly arranged on the top of the operating table 1, support columns 3 are fixedly arranged at the four corners of the bottom of the operating table 1, and the bottom of the support columns 3 are all plugged with bases 4, and the middle of the two bases 4 along the conveying direction of the roller conveyor 2 are penetrated by a detachable and fixed rectangular body 5. A placement rack 8 is also arranged at the end of the roller conveyor 2 closer to the sintering furnace, and a touch switch is arranged on the top of the placement rack 8.

[0029] In order to improve the sintering efficiency, in this embodiment, see Figure 1 and Figure 2 The roller conveyor 2 is provided with a sintering plate 11 that matches the roller conveyor 2. The distance between the two sides of the sintering plate 11 perpendicular to the conveying direction of the roller conveyor 2 is equal to the distance between the baffles on both sides of the roller conveyor 2, so that stable conveying can be achieved. Matching grooves 111 are provided in the middle of both sides of the sintering plate 11 perpendicular to the conveying direction of the roller conveyor 2. Flow holes 112 are provided in the middle of the tops of both sides of the sintering plate 11 along the conveying direction of the roller conveyor 2 to facilitate air circulation during sintering.

[0030] In order to allow the sintering trays to be stacked, in this embodiment, see Figure 2 and Figure 3, a clamping assembly 10 is provided on the placement rack 8 on both sides of the roller conveyor 2. The clamping assembly 10 includes a clamping telescopic rod 101, which is fixedly provided on the placement rack 8, and an L-shaped clamping plate 102 is fixedly provided at the telescopic end of the clamping telescopic rod 101, and a touch switch is provided on the bottom side of the L-shaped clamping plate 102. Clamping grooves 21 are correspondingly provided on the baffles on both sides of the roller conveyor 2 just below the L-shaped clamping plate 102. During the upward displacement of the sintering disk 11, it will first touch the touch switch provided on the bottom side of the L-shaped clamping plate 102. At this time, the control module controls the clamping telescopic rod 101 to drive the L-shaped clamping plate 102 to retract first and then extend and reset. When the last sintering disk 11 is stacked, when moving upward, the edge of the sintering disk 11 will touch the touch switch on the top of the placement rack 8, and at this time all the telescopic rods of the device will retract.

[0031] In order to enable the roller conveyor to move in the vertical direction, in this embodiment, see Figure 3 The rectangular body 5 is provided with a lifting assembly 6, and the lifting assembly 6 includes a slide rail 61, and the slide rail 61 is detachably fixed at the bottom of the rectangular body 5. Two sliding push blocks 62 are slidably provided on the slide rail 61, and the two sliding push blocks 62 are fixedly connected by a connecting piece 64. A driving telescopic rod 63 is fixedly provided at one end of the rectangular body 5, and its telescopic end is fixedly connected to the sliding push block 62. The lifting assembly 6 also includes a connecting column 66 and a limiting column 65. The connecting column 66 is fixedly provided at the bottom of the supporting column 3. A through hole is provided at the top of the rectangular body 5 directly below the connecting column 66. The limiting column 65 is fixedly provided in the through hole. The connecting column 66 is slidably inserted in the limiting column 65, and a pulley 67 is fixedly provided at the bottom of the connecting column 66. A buffer return spring 7 is arranged between the pulley 67 and the limit column 65. When impacted by external force, the buffer return spring 7 can absorb part of the energy, reduce the impact force of the sliding push block 62 on the pulley 67, and play a buffering role. After the external force disappears, the buffer return spring 7 can release the absorbed energy and play a resetting role.

[0032] In order to enable the sintering trays to be stacked at a fixed point, in this embodiment, see Figure 2 and Figure 3, a guard assembly 9 is provided at one end of the roller conveyor 2 closer to the sintering furnace, and the guard assembly 9 includes a guard telescopic rod 91, and the guard telescopic rod 91 is fixedly provided at the end of the roller conveyor 2, and an L-shaped baffle 92 is fixedly provided at the telescopic end of the guard telescopic rod 91. When the telescopic end of the guard telescopic rod 91 is fully retracted, the top surface of the L-shaped baffle 92 is equal to the height of the highest point of the roller cross section of the roller conveyor 2, so that when the sintering disk 11 is transported, it serves as a conveying mechanism connected to the sintering furnace. The vertical plate portion of the L-shaped baffle 92 is provided with a touch switch. When the sintering disk 11 is transported to the end of the roller conveyor 2 and touches the touch switch on the L-shaped baffle 92, the driving telescopic rod 63 of the lifting assembly 6 drives the other components to complete a reciprocating motion, so that the support column 3 first moves upward and then resets, and then the roller conveyor 2 and the sintering disk 11 thereon will simultaneously move upward to the highest point and then move downward to reset.

[0033] The working principle of the automatic placing device for firing high-purity alumina ceramic sheets of the utility model is as follows: the vertical plate portion of the L-shaped baffle plate 92 is provided with a touch switch. When the sintering disk 11 is transported to the end of the roller conveyor 2 and touches the touch switch on the L-shaped baffle 92, the driving telescopic rod 63 of the lifting assembly 6 drives the other components to complete a reciprocating motion, so that the support column 3 first moves upward and then resets, and then the roller conveyor 2 and the sintering disk 11 thereon will simultaneously move upward to the highest point and then move downward to reset. At this time, the sintering disk 11 will first touch the touch switch provided on the bottom side of the L-shaped clamping plate 102 during the upward displacement. At this time, the control module controls the clamping telescopic rod 101 to drive the L-shaped clamping plate 102 to first retract and then extend and reset. When the L-shaped clamping plate 102 retracts, the sintering disk 11 on the roller conveyor 2 continues to move upward to the maximum value. At this time, the L-shaped clamping plate 102 extends and resets, and passes through the gap formed by the clamping groove 21 opened on the baffle of the roller conveyor 2 and the matching groove 111 on the sintering disk 11 to lift the bottom of the sintering disk 11. At the same time, the roller conveyor 2 continues to move downward and reset, and repeats this process. When the last sintering disk 11 is stacked, the edge of the sintering disk 11 will touch the touch switch on the top of the placement rack 8 when moving upward. At this time, all the telescopic rods of the device are retracted. When the telescopic end of the protective telescopic rod 91 is fully retracted, the top surface of the L-shaped baffle 92 is equal to the height of the highest point of the roller cross section of the roller conveyor 2, so that the sintering disks 11 stacked on the roller conveyor 2 can be smoothly transported to the conveying mechanism of the sintering furnace for sintering and conveying.
