[0002] MLCCs are made of ceramic dielectric diaphragms with printed electrodes (internal electrodes) stacked in an offset pattern. They undergo a single high-temperature sintering process to form a ceramic chip, which is then sealed with a metal layer at both ends. MLCCs are a crucial component of printed circuit boards.

[0003] During the manufacturing process, MLCC undergoes debinding treatment, which mainly removes the doped adhesive. The implementation method is also relatively simple. You only need to place the cut blank into a heating furnace.

[0004] The existing processing method requires laying out a single embryo on a carrier, and then placing the carrier into a heating furnace. The heating furnace is equipped with multiple supporting brackets, and the carriers need to be placed one by one on the brackets. This process requires manual operation, making the preparation work for debonding more complicated. Summary of the Invention

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0030] like Figure 1 and Figure 2 FIG. 1 is a structural diagram of an MLCC green body debinding and firing furnace device provided by one embodiment of the present invention, comprising:

[0031] The base 1 is fixedly connected to the furnace body 2, and a cover door 3 is rotatably hinged on one side of the furnace body 2. A heating unit 4 is also provided in the furnace body 2, and further includes:

[0032] There are two support shafts 5 , which are rotatably arranged at the top and bottom of the box body, and are both located on the side away from the cover door 3 .

[0033] The mounting rollers 6 are fixedly sleeved on the support shaft 5 , and the mounting rollers 6 on both sides are wound with transmission belt assemblies 7 , and the transmission belt assemblies 7 are fixedly provided with a plurality of connecting pieces 8 at intervals.

[0034] The driving box 9 is arranged outside the furnace body 2 and is used to drive the support shaft 5 located at the bottom of the furnace body 2 to rotate.

[0035] The receiving tray 10 has a connector 8 fixed on one side thereof that cooperates with the transmission belt assembly 7. When the connector 8 on the receiving tray 10 contacts the connector 8 on the transmission belt assembly 7, the transmission belt assembly 7 is used to drive the receiving tray 10 to move in the vertical direction.

[0036] In one embodiment of the present invention, when the device is in use, the embryos to be debonded are first placed on the receiving tray 10, then the cover door 3 is opened, and the receiving tray 10 is pushed into the furnace body 2. The receiving tray 10 can be fixed on the transmission belt assembly 7 through the connecting piece 8, and then the transmission belt assembly 7 is driven to rotate by the driving box 9, so that the receiving tray 10 can be lifted to a high place. By rotating the transmission belt assembly 7, several receiving trays 10 containing the embryos are suspended in the furnace body 2. Unlike manual operation which requires constant up and down picking and storage, this method makes the embryo loading work simpler and reduces the workload of the operator.

[0037] In one embodiment of the present invention, the connector 8 can be connected by magnets. This method is fast and efficient, but there are cases where the connection is unstable, such as Figure 4 As shown, the connecting member 8 can also adopt the structural form of the hook 11, which can stably ensure that the receiving plate 10 is fixed on the transmission belt assembly 7; Figure 6 As shown, the receiving tray 10 is provided with a plurality of evenly distributed placement grooves 12, which can be used to place the embryos with debonding in the placement grooves 12. Therefore, even after the receiving tray 10 is shaken, the embryos on the receiving tray 10 will not shake and fall off. Figure 1 As shown, an operating table 13 is fixedly provided on the outside of the furnace body 2. The operating table 13 and the cover door 3 are located on the same side of the furnace body 2. A display screen 1301 is provided on the operating table 13 to display temperature data. Of course, the operating table 13 is also provided with buttons 1302 for controlling the heating unit 4 and the forward and reverse rotation of the transmission belt assembly 7, which are convenient for operation. The heating unit 4 can adopt a resistance wire heating method, and of course, a hot air blowing structure can also be adopted; a reserved space is provided between the inner wall of the furnace body 2 and the transmission belt assembly 7, so that when the transmission belt assembly 7 rotates, the connecting member 8 will not interfere with the inner wall of the furnace body 2; Figure 7As shown, the transmission belt assembly 7 and the conveyor belt assembly 18 are composed of a number of plates 14 connected in series by steel cables 15, and the suspension parts are fixedly connected to the plates 14. Since the temperature inside the furnace body 2 is relatively high, it is not suitable to use a traditional rubber conveyor belt. Therefore, this structure can ensure that the two will not produce large deformation, thereby causing the transmission belt assembly 7 and the conveyor belt assembly 18 to slip during rotation.

[0038] like Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the rotating hinge between the cover door 3 and the furnace body 2 is located at the bottom, and the cover door 3 and the furnace body 2 are both rotatably connected with a mounting shaft 16, the mounting shaft 16 in the furnace body 2 is located on the side of the support shaft 5 facing the cover door 3, and a reserved gap 20 is provided between the support shaft 5 and the mounting shaft 16, the mounting shaft 16 on the cover door 3 is located on the side away from the rotating hinge between the cover door 3 and the furnace body 2, a belt roller 17 is fixedly sleeved on the mounting shaft 16, and a conveyor belt assembly 18 is fixedly connected to the belt roller 17. When the cover door 3 is at the maximum opening and closing degree, the cover door 3 itself is in a horizontal state, and at this time the conveyor belt assembly 18 is in a taut and horizontal state, and a transmission structure 23 for connecting the mounting shaft 16 and the support shaft 5 is provided in the drive box 9. When the support shaft 5 rotates, the mounting shaft 16 and the support shaft 5 keep rotating in the same direction.

[0039] In one case of this embodiment, when the cover door 3 is opened, it means that the embryo body is either placed into the furnace body 2 or taken out of the furnace body 2. When the embryo body is placed into the furnace body 2, the receiving tray 10 can be placed on the conveyor belt assembly 18. At this time, the driving box drives the support shaft 5 and the installation shaft 16 to rotate, which will cause the receiving tray 10 to move into the furnace body 2 and the connecting member 8 on the transmission belt assembly 7 to move upward. When the receiving tray 10 is in contact with the transmission belt assembly 7, as the connecting member 8 moves upward, the receiving tray 10 can be hooked and lifted. When the embryo body needs to be taken out of the furnace body 2, the transmission belt assembly 7 is rotated in the opposite direction so that multiple receiving trays 10 can be lifted. The tray 10 moves downward. At this time, due to the lateral blocking effect of the conveyor belt assembly 18, the receiving tray 10 will fall onto the conveyor belt assembly 18, and the connecting parts 8 will separate from each other, so that the conveyor belt assembly 18 will move the receiving tray 10 out of the furnace body 2. Therefore, when loading, the receiving tray 10 can be automatically hung on the transmission belt assembly 7 in sequence, and when unloading, the receiving tray 10 can be automatically dropped onto the conveyor belt assembly 18 in sequence for delivery. This method is more efficient; the width of the conveyor belt assembly 18 is smaller than the width of the transmission belt assembly 7, which can ensure that the receiving tray 10 placed on the conveyor belt assembly 18 is stably connected to the connecting parts 8 on the transmission belt assembly 7; Figure 3As shown, a horizontal pad 19 is provided in the reserved interval 20, and both ends of the pad 19 are fixedly connected to the furnace body 2. When the conveyor belt assembly 18 is in a horizontal state, the pad 19 is flush with the surface of the conveyor belt assembly 18. Since the conveyor belt assembly 18 and the transmission belt assembly 7 need to rotate separately, there must be a reserved interval 20 between the two. This reserved interval 20 may cause the receiving tray 10 to tilt, making it impossible for the two connecting members 8 to be accurately connected. Therefore, the pad 19 is provided to ensure that the receiving tray 10 remains in a horizontal state and ensures that the receiving tray 10 can be stably suspended on the transmission belt assembly 7; as shown Figure 3 As shown, the cover door 3 is fixedly connected to a switch handle 21. When the cover door 3 is in a horizontal state, the switch handle 21 contacts the ground. In addition to opening or covering the door 3, the switch handle 21 can also play a supporting role to ensure that the cover door 3 remains in a horizontal state after opening. Figure 5 As shown, a motor 22 is provided in the driving box 9, and the output end of the motor 22 is connected to the support shaft 5, and the transmission structure 23 between the support shaft 5 and the mounting shaft 16 can adopt a belt drive method, and of course a chain drive method can also be adopted.
