Description

TECHNICAL FIELD

[0001] The present application relates to the field of sintering furnace, in particular to a ceramic body sintering furnace. BACKGROUND

[0002] In the processing flow of ceramic electrostatic chuck, ceramic body needs to complete high-temperature heat treatment by means of sintering furnace, so as to promote the close combination and densification between ceramic particles, so as to meet the performance requirements of products.

[0003] And the sintering furnace is usually equipped with a blank holder for carrying ceramic bodies, but the blank holder generally adopts a multi-layer structure design. In actual operation, when the blank body needs to be taken and placed in the lower area, the upper layer plate will form an obstruction, resulting in limited operation space and inconvenient taking and placing of ceramic bodies. In order to solve this problem, if each layer plate is designed as a structure that can automatically adjust and move, although it can effectively avoid the taking and placing problem caused by obstruction, the electrical components (such as motors) involved in the adjusting structure will enter the sintering furnace together with the layer plate during the sintering process. Because the temperature in the sintering furnace is very high, these electrical components are easily damaged by high temperature, thereby affecting the normal operation and service life of the equipment.

[0028] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0029] like Figures 1-9 As shown, the ceramic blank sintering furnace includes a support frame 1; the sintering furnace body 2 is fixedly mounted on the support frame 1; and also includes: The cover 3 is located on the inlet side of the sintering furnace body 2. A translation part for opening or closing the cover 3 is installed on the outer wall of the sintering furnace body 2. The translation part is a first telescopic rod 4. There are two first telescopic rods 4. The two first telescopic rods 4 are respectively fixedly installed on the top outer wall and the bottom outer wall of the sintering furnace body 2. The output end of the first telescopic rod 4 is fixedly connected to the cover 3. By extending and retracting the first telescopic rod 4, the cover 3 is moved so that the cover 3 moves away from or closer to the inlet of the sintering furnace body 2, thereby opening or closing.

[0030] A fixed carrier plate 6 is fixedly installed at the bottom of the cover 3 by welding (or bolt connection, etc.). Multiple movable carrier plates 5 are arranged at equal intervals along the vertical direction above the fixed carrier plate 6. Each of the multiple movable carrier plates 5 is provided with a rotating connection part on one side, and the multiple rotating connection parts are located on the same vertical line. The movable carrier plates 5 are connected to the side of the cover 3 facing the sintering furnace body 2 through the rotating connection parts, and the rotating connection parts are provided with square holes 503. A square column 9 is vertically arranged, and a rotary drive assembly 8 is provided at the top of the square column 9. The rotary drive assembly 8 is connected to a lifting part for driving the square column 9 to rise and fall and positioning the square column 9 at the height of the square hole 503 corresponding to different movable carrier plates 5. The lifting part is a second telescopic rod 7, which is vertically arranged and fixedly installed on the side of the cover 3 away from the sintering furnace body 2. The second telescopic rod 7 extends and retracts to drive the rotary drive assembly 8 and the square column 9 to move up and down together to insert into or pull out of the square hole 503.

[0031] The lifting unit drives the square column 9 to precisely stop at different height positions (corresponding to the movable carrier plate 5 of different layers), selectively establishing a connection between the square column and the movable carrier plate 5 of different layers. This allows the movable carrier plate 5 at any layer to be moved above the square column 9, thus eliminating obstruction.

[0032] In the above, the first telescopic rod 4 and the second telescopic rod 7 are pneumatic cylinders or hydraulic cylinders.

[0033] The self-locking mechanism 14 is provided with a socket 502 on the side of the movable carrier plate 5 facing the cover 3, and a slot for inserting the socket 502 is provided on the side wall of the cover 3. The self-locking mechanism 14 is installed in the socket 502. The unlocking part is connected to the self-locking mechanism 14, and the input end of the unlocking part is disposed in the square hole 503.

[0034] like Figure 3 , Figure 4 , Figure 6 as well as Figure 7 As shown, as a specific technical solution, the rotating connection part includes a fixing frame 10, which is fixedly installed on the side of the cover 3 facing the sintering furnace body 2. A side frame 501 is provided on one side of the movable carrier plate 5, and a round shaft is provided in the middle of the side frame 501. A round hole that mates with the round shaft is opened on the fixing frame 10, and the round shaft is rotatably disposed in the round hole. The square hole 503 is opened at the axis of the round shaft.

[0035] like Figure 7As shown, as a specific technical solution, the top and bottom of the fixing frame 10 are both provided with circular holes, which are connected to the circular shaft. The top and bottom ends of the circular shaft extend outwards to form retaining edges, which respectively fit against the top and bottom surfaces of the fixing frame 10. Rotational installation is achieved through the circular shaft and circular holes; the retaining edges prevent vertical relative movement between the circular shaft and the fixing frame 10, allowing only relative rotation between them.

[0036] When the square column 9 is inserted into the square hole 503, the square column 9 is rotated by the rotation drive assembly 8, and the side frame 501 and the round shaft rotate together with the square column 9, causing the movable carrier plate 5 to flip away from one side of the cover 3, thus removing the obstruction of the movable carrier plate 5 or the fixed carrier plate 6 below, making it convenient to put on and take off the ceramic blank on the top surface of the movable carrier plate 5 or the fixed carrier plate 6 below.

[0037] As an example, such as Figures 3-4 As shown, three movable carrier plates 5 are used. When placing or removing the ceramic blank from the top surface of the fixed carrier plate 6, the second telescopic rod 7 drives the square column 9 to be inserted into the square hole 503 on one side of all movable carrier plates 5. Driving the square column 9 to rotate can cause all movable carrier plates 5 to flip, so that the top surface of the fixed carrier plate 6 is no longer obstructed. After the ceramic blank is placed or removed from the top surface of the fixed carrier plate 6, all movable carrier plates 5 are driven to return to their original positions. Figures 3-4 As shown.

[0038] When placing or removing the ceramic blank from the top surface of the bottom movable carrier plate 5, the second telescopic rod 7 drives the square column 9 upward, causing the square column 9 to move away from the square hole 503 on one side of the bottom movable carrier plate 5. Then, the square column 9 is driven to rotate, causing the other movable carrier plates 5 except the bottom movable carrier plate 5 to flip over, so that the bottom movable carrier plate 5 is no longer obstructed. After the movable carrier plate 5 has completed the placement or removal of the ceramic blank, the other movable carrier plates 5 above it are driven to return to their original positions. Figures 3-4 As shown; similarly, when the second or third movable carrier plate 5 from the bottom needs to pick up or put down the ceramic blank, the height of the square column 9 is adjusted, and then the square column 9 drives the movable carrier plate 5 that is causing the obstruction to flip over, so as to remove the obstruction and facilitate the picking up or putting down of the ceramic blank.

[0039] In practice, the number and spacing of the movable carrier plates 5 are adjusted according to specific requirements.

[0040] like Figure 5As shown, as a specific technical solution, the rotary drive assembly 8 includes a frame 801; the frame 801 is fixedly installed at the top of the lifting part, a motor 802 is fixedly installed on one side of the frame 801, a rotating shaft is rotatably installed on the top of one side of the frame 801, and a second transmission wheel 804 is installed on the rotating shaft, a first transmission wheel 803 is installed on the output shaft of the motor 802, a transmission belt 805 is wound between the first transmission wheel 803 and the second transmission wheel 804, and the square column 9 is located below one side of the frame 801, and the top of the square column 9 is fixedly connected to the bottom of the rotating shaft.

[0041] The rotary drive assembly 8 is used to drive the square column 9 to rotate. The motor 802 drives the first transmission wheel 803 to rotate, and then the transmission belt 805 drives the second transmission wheel 804 and the rotating shaft to rotate together, thereby driving the square column 9 to rotate. When the square column 9 is inserted into the square hole 503, it can drive the movable carrier plate 5 to flip.

[0042] The lifting unit is used to drive the rotary drive assembly 8 and the square column 9 to move up and down together. It is used to adjust the number of movable carrier plates 5 connected to the square column 9. After the ceramic blank is placed on the top surface of the movable carrier plate 5 and the top surface of the fixed carrier plate 6, the square column 9 and the rotary drive assembly 8 are moved to the highest position and away from the side of the cover 3. After the cover 3 is closed, the rotary drive assembly 8 and the square column 9 do not enter the interior of the sintering furnace body 2 to avoid being affected by high temperature.

[0043] like Figure 3 , Figure 4 , Figure 8 as well as Figure 9 As shown, as a specific technical solution, the slot part is composed of two clamping plates 11; the two clamping plates 11 form an insertion groove, and each of the two clamping plates 11 is provided with a locking hole 1101.

[0044] There are multiple slots, which are used for the insertion of multiple side sockets 502 on the movable carrier plate 5. After the socket 502 is inserted into the insertion slot and the square post 9 leaves the square hole 503, the unlocking of the self-locking mechanism 14 is canceled, and the self-locking mechanism 14 automatically locks, so that the lock block 1402 is inserted into the lock hole 1101.

[0045] like Figure 9As shown, as a specific technical solution, the movable carrier plate 5 has an inner cavity 504 on the side near the cover 3; the self-locking mechanism 14 is disposed in the inner cavity 504 located at the socket 502, and the self-locking mechanism 14 includes a pressing block 1401 and a locking block 1402; the pressing block 1401 has an isosceles trapezoidal cross section, and the top and bottom of the pressing block 1401 are provided with a third inclined surface 14011; the locking block 1402 has a fourth inclined surface 14021 on the side near the pressing block 1401, and the third inclined surface 14011 abuts against the fourth inclined surface 14021. The socket 502 has through grooves 506 at both the top and bottom, and the through grooves 506 communicate with the inner cavity 504. The locking block 1402 is slidably connected to the through grooves 506. A side seat 1403 is fixedly installed on one side of the locking block 1402. A sliding hole is provided on the side seat 1403. A guide rod 1405 is fixedly installed in the inner cavity 504 of the socket 502. The sliding hole is slidably sleeved with the guide rod 1405. Two second springs 1404 are sleeved on the guide rod 1405. The side seat 1403 is elastically connected to the wall of the inner cavity 504 through the second springs 1404.

[0046] There are two locking blocks 1402, and the two locking blocks 1402 are symmetrically arranged on the upper and lower sides of the pressing block 1401.

[0047] like Figures 7-8 As shown, as a specific technical solution, the unlocking part includes a movable block 12 and a transmission assembly 13; the movable block 12 is the input end of the unlocking part, and a sliding groove 505 communicating with the inner cavity 504 is provided on the side wall of the square hole 503. The sliding groove 505 is slidably connected to the movable block 12, and the transmission assembly 13 is disposed in the inner cavity 504. One end of the movable block 12 extending into the inner cavity 504 is connected to the transmission assembly 13.

[0048] like Figure 8 As shown, as a specific technical solution, the transmission assembly 13 includes a straight bar 1301; one end of the straight bar 1301 is fixedly connected to the movable block 12, and the other end of the straight bar 1301 is fixedly connected to a connecting rod 1304. The connecting rod 1304 is fixedly connected to the pressing block 1401. A plurality of first springs 1302 are provided on one side of the straight bar 1301. The straight bar 1301 is elastically connected to the wall of the inner cavity 504 through the first springs 1302. A plurality of guide posts 1303 are fixedly installed on the wall of the inner cavity 504. A guide hole is opened on the straight bar 1301, and the guide hole is slidably sleeved with the guide post 1303.

[0049] like Figure 7As shown, as a specific technical solution, the movable block 12 is provided with a second inclined surface 1201 on one side inside the square hole 503, and the bottom side of the square column 9 is provided with a first inclined surface 901 adapted to the second inclined surface 1201.

[0050] In the active carrier plate 5, as Figures 3-4 In the indicated state, the socket 502 is inserted into the insertion slot of the slot portion, and the locking block 1402 of the self-locking mechanism 14 is inserted into the lock hole 1101 to lock and limit the movement of the movable carrier plate 5.

[0051] The square column 9 is inserted into the square hole 503. The first inclined surface 901 presses against the second inclined surface 1201 to push the movable block 12 away from the square hole 503. At the same time, the movable block 12 pushes the straight bar 1301 to move and stretches the first spring 1302, increasing the stretch of the first spring 1302. The first spring 1302 is in a stretched state when the movable block 12 is pushed. When the straight bar 1301 moves, the straight bar 1301 drives the pressing block 1401 away from the guide rod 1405 through the connecting rod 1304. The locking block 1402, through the compression force of the second spring 1404, keeps its fourth inclined surface 14021 abutting against the third inclined surface 14011 of the pressing block 1401. This causes the locking block 1402 to move towards the inner side of the inner cavity 504 and separate from the lock hole 1101, completing the automatic unlocking. When the square column 9 rotates later, it can drive the movable carrier plate 5 to flip.

[0052] The movable carrier plate 5 flips away to facilitate the removal and placement of the ceramic blank from the top surface of the movable carrier plate 5 or the fixed carrier plate 6 below it. Then, the movable carrier plate 5 is returned to its original position. Figures 3-4 After reaching the indicated state, the socket 502 is inserted between the two clamping plates 11, and the end face of the socket 502 away from the movable carrier plate 5 is in contact with the cover 3. At this time, the locking block 1402 is aligned with the locking hole 1101. Then, the square post 9 is pulled out from the square hole 503, and the movable block 12 is no longer obstructed. Through the elastic force of the first spring 1302, the straight bar 1301 drives the movable block 12 to reset and move. The end of the movable block 12 enters the square hole 503, returning to the position shown. Figure 7 In the indicated state, the straight bar 1301, via the connecting rod 1304, drives the pressing block 1401 closer to the guide rod 1405. The pressing block 1401, through the third inclined surface 14011, presses the fourth inclined surface 14021 of the locking block 1402, causing the two locking blocks 1402 to move away from each other. The locking blocks 1402 are inserted into the lock hole 1101, and the locking blocks 1402 drive the side seat 1403 to move together, compressing the second spring 1404, and returning to the state as shown. Figure 9 As shown, automatic locking is completed to maintain the stability of the movable carrier plate 5. After locking, the first spring 1302 remains in a stretched state, while the second spring 1404 is in a compressed state. The elastic forces of the two cancel each other out, maintaining the locking mechanism 14 and the unlocking part.Figures 7-9 The state shown.

[0053] The guide post 1303, in conjunction with the guide hole on the straight bar 1301, provides guidance for the movement of the straight bar 1301; the guide rod 1405, in conjunction with the sliding hole on the side seat 1403, provides guidance for the movement of the locking block 1402.

[0054] The preload or stiffness setting of the first spring 1302 must ensure that, when the square post 9 is not inserted, it can drive the movable block 12 to reset and move the pressing block 1401 to the locked position; the preload or stiffness setting of the second spring 1404 must ensure that, when the pressing block 1401 moves to the locked position, it can reliably push out the locking block 1402 and keep it in the lock hole 1101. The spring force parameters of the two springs must be matched to ensure the reliability of the self-locking and unlocking actions.

[0055] Through the above design, when the movable carrier plate 5 needs to be flipped, the locking of the movable carrier plate 5 is automatically released during the process of the square column 9 being inserted into the square hole 503. After the movable carrier plate 5 is reset, the square column 9 is pulled out from the square hole 503, canceling the unlocking of the self-locking mechanism 14, which then automatically locks the movable carrier plate 5. This ensures the stability of the movable carrier plate 5 when placing the ceramic blank, while eliminating the need for manual operation in locking and unlocking the movable carrier plate 5, thus providing convenience for overall use.
