Description

Technical Field

[0001] This utility model relates to the field of glue removal furnace technology, specifically to an MLCC glue removal furnace. Background Technology

[0002] MLCCs are fundamental components widely used in electronic devices. Their production involves several key process steps, including molding, debinding, pre-firing, and sintering. Among these, debinding is a crucial step in removing organic adhesives and binders adhering to the surface or interior of MLCCs. If these organic substances are not completely removed, they will cause defects such as bubbles and cracks during subsequent high-temperature sintering, seriously affecting the quality and performance of the product. Current debinding furnaces are devices that remove organic adhesives and binders from the surface or interior of multilayer ceramic capacitors through high-temperature heating. Their core working principle is to precisely control the temperature, time, and hot air circulation to cause thermal decomposition or volatilization of organic substances, thereby ensuring that MLCC products have good quality and performance during subsequent sintering. The exhaust gas is discharged through an exhaust pipe after purification. However, most debinding furnaces lack detection structures, making it difficult to analyze the composition of the purified exhaust gas in the exhaust pipe. This may result in unqualified exhaust gas being directly discharged into the environment, causing pollution, and also reducing the flexibility of the debinding furnace. Utility Model Content

[0003] The purpose of this invention is to provide an MLCC glue removal furnace to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an MLCC glue removal furnace, comprising a furnace body, an exhaust pipe fixedly connected to the top of the furnace body, a circulation pipe fixedly connected to the outer surface of the exhaust pipe, valve one, valve two, and valve three rotatably connected inside the exhaust pipe, an adjustment structure connected to the outside of the exhaust pipe, the adjustment structure being connected to valve one, valve two, and valve three, a snap-fit ​​structure connected to the outside of the exhaust pipe, a detection cylinder snapped into the exhaust pipe, a positioning block and a limiting block fixedly connected to the outside of the detection cylinder, the snap-fit ​​structure snapping into the limiting block, and the adjustment structure comprising a motor, anti-slip belt one, and anti-slip belt two.

[0005] As a further preferred embodiment of this technical solution, a controller is fixedly connected to the top of the furnace body, a cabinet door is provided on one side of the furnace body, and the motor is fixedly connected to the outside of the exhaust pipe.

[0006] As a further preferred embodiment of this technical solution, the output shaft of the motor is connected to valve two, valve two is connected to valve one via anti-slip strip one, and valve three is connected to valve two via anti-slip strip two.

[0007] As a further preferred embodiment of this technical solution, the positioning block is engaged inside the exhaust pipe. The engaging structure includes a fixed ring and a movable ring. A cross block is fixedly connected below the movable ring, and the cross block is engaged inside the limiting block.

[0008] As a further preferred embodiment of this technical solution, the cross block is provided with bolts, the cross block is connected to the limiting block by bolts, and a moving rod is fixedly connected above the moving ring.

[0009] As a further preferred embodiment of this technical solution, the movable rod is fitted with a spring, and the movable ring is connected to the fixed ring through the spring.

[0010] This utility model provides an MLCC debinding furnace, which has the following beneficial effects:

[0011] (1) This utility model sets up valve one, valve two, valve three, detection cylinder and adjustment structure. When unqualified is detected, valve two is driven by motor to rotate. Since valve two is connected to valve one through anti-slip belt one and valve three is connected to valve two through anti-slip belt two, valve one, valve two and valve three will rotate synchronously. When valve two and valve three are closed, the unqualified exhaust gas will enter the external purifier through the circulation pipe. When qualified, valve two and valve three will open and valve one will close. Through the coordination between the adjustment structure, detection cylinder and circulation pipe, the glue degassing furnace can analyze the composition of the purified exhaust gas in the exhaust pipe and promptly discharge the unqualified exhaust gas into the external purifier for secondary treatment, avoiding direct discharge into the environment and causing pollution. At the same time, it also ensures the flexibility of the glue degassing furnace.

[0012] (2) By setting up a snap-fit ​​structure, when the moving ring is pushed, it will slide on the surface of the exhaust pipe. The fixed ring will drive the spring to deform, and the moving rod will slide inside the fixed ring. The detection cylinder will be snapped into the exhaust pipe by the limiting block. The positioning block on the surface of the detection cylinder will be snapped into the exhaust pipe. When the detection cylinder and the exhaust pipe are completely in contact, the moving ring will be released and reset by the action of the spring. After reset, the cross block below the moving ring will be snapped into the limiting block. The cross block will then be threadedly connected to the limiting block by bolts, so that the detection cylinder and the exhaust pipe can be quickly assembled, and the detection cylinder can be easily replaced or repaired later.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, an MLCC glue removal furnace includes a furnace body 1. An exhaust pipe 2 is fixedly connected to the top of the furnace body 1. A circulation pipe 3 is fixedly connected to the outer surface of the exhaust pipe 2. A valve 11, a valve 22, and a valve 33 are rotatably connected inside the exhaust pipe 2. An adjustment structure 6 is connected to the outside of the exhaust pipe 2. The adjustment structure 6 is connected to the valve 11, the valve 22, and the valve 33. A snap-fit ​​structure 7 is connected to the outside of the exhaust pipe 2. A detection cylinder 8 is snapped into the exhaust pipe 2. A positioning block 10 and a limiting block 9 are fixedly connected to the outside of the detection cylinder 8. The snap-fit ​​structure 7 snaps into the limiting block 9. The adjustment structure 6 includes a motor 601, an anti-slip belt 1 602, and an anti-slip belt 2 603.

[0020] like Figure 1 and Figure 3 As shown, a controller 5 is fixedly connected to the top of the furnace body 1, a cabinet door 4 is provided on one side of the furnace body 1, a motor 601 is fixedly connected to the outside of the exhaust pipe 2, the output shaft of the motor 601 is connected to valve 2 12, valve 2 12 is connected to valve 1 11 through anti-slip belt 1 602, and valve 3 13 is connected to valve 2 12 through anti-slip belt 2 603.

[0021] By setting anti-slip belt 1 602 and anti-slip belt 2 603, the motor 601 drives valve 2 12 to rotate. Since valve 2 12 is connected to valve 1 11 through anti-slip belt 1 602 and valve 3 13 is connected to valve 2 12 through anti-slip belt 2 603, valve 1 11, valve 2 12 and valve 3 13 can achieve synchronous rotation, which facilitates the control of the exhaust gas emission path and avoids unqualified exhaust gas from being directly discharged into the air.

[0022] like Figure 4 As shown, the positioning block 10 is snapped into the exhaust pipe 2. The snapping structure 7 includes a fixed ring 701 and a movable ring 702. A cross block 703 is fixedly connected to the lower part of the movable ring 702. The cross block 703 is snapped into the limiting block 9. A bolt 704 is provided inside the cross block 703. The cross block 703 is connected to the limiting block 9 through the bolt 704. A movable rod 705 is fixedly connected to the upper part of the movable ring 702. A spring 706 is sleeved on the movable rod 705. The movable ring 702 is connected to the fixed ring 701 through the spring 706.

[0023] By setting the spring 706, a pushing force is applied to the moving ring 702. When the moving ring 702 slides on the surface of the exhaust pipe 2, it will cause the spring 706 to deform through the fixed ring 701, and the moving rod 705 will slide inside the fixed ring 701. This allows the spring 706 to provide a certain support for the movement of the moving ring 702. When the moving ring 702 loses resistance, it will be reset by the spring 706.

[0024] This utility model provides an MLCC glue removal furnace, the specific working principle of which is as follows:

[0025] When the degreasing furnace is in use, a pushing force is applied to the moving ring 702. When the moving ring 702 slides on the surface of the exhaust pipe 2, it will cause the spring 706 to deform through the fixed ring 701, and the moving rod 705 will slide inside the fixed ring 701. The detection cylinder 8 is locked into the exhaust pipe 2 through the limit block 9, and the positioning block 10 on the surface of the detection cylinder 8 will be locked into the exhaust pipe 2. When the detection cylinder 8 and the exhaust pipe 2 are completely in contact, the moving ring 702 is released, and the moving ring 702 will be reset by the action of the spring 706. After reset, the cross block 703 below the moving ring 702 will be locked into the limit block 9, and the cross block 703 will be threadedly connected to the limit block 9 through the bolt 704.

[0026] By precisely controlling the temperature, time, and hot air circulation, organic matter undergoes thermal decomposition or volatilization, ensuring the MLCC product maintains good quality and performance during subsequent sintering. The purified exhaust gas is discharged through exhaust pipe 2. Upon discharge, the exhaust gas passes through detection cylinder 8 for testing. If a defect is detected, motor 601 drives valve 12 to rotate. Since valve 12 is connected to valve 11 via anti-slip band 602, and valve 13 is connected to valve 12 via anti-slip band 603, valves 11, 22, and 13 rotate synchronously. When valves 12 and 13 close, the defective exhaust gas enters the external purifier through circulation pipe 3. When the gas passes the test, valves 12 and 13 open while valve 11 closes.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
