[Specific implementation method]

[0034] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0035] Please refer to Figures 1 and 2. Figure 1 is a cross-sectional view of an embodiment of the processing device of the present application; Figure 2 is a side view of an embodiment of the processing device of the present application. The present application provides a processing device. The processing device includes a furnace body 10, a cavity 20, and a limiting assembly 30. The furnace body 10 is placed on a frame of the processing device (not shown in the figure), and the furnace body 10 is fixed. The furnace body 10 is formed with an opening (not shown in the figure). The cavity 20 is located on the inner side of the furnace body 10, and the product is placed in the cavity 20 for reaction. The cavity 20 is sleeved on the furnace body 10 through the opening. That is, the cavity 20 is placed into the furnace body 10 from the opening of the furnace body 10. The cavity 20 is provided with an extension portion 21 extending from the opening. The extension portion 21 is located between the opening of the furnace body 10 and the furnace door 11. The portion of the cavity 20 extending out of the opening of the furnace body 10 is the extension portion 21. The extension portion 21 is fixedly connected to the cavity 20 or integrally formed.

[0036] The limiting assembly 30 is fixed relative to the cavity 20. The limiting assembly 30 can be placed on the outer circumferential surface of the extension 21. Alternatively, as described below, the limiting assembly 30 can be clamped to the protrusion 22 on the outer circumferential surface of the extension 21. The limiting assembly 30 is used to limit the movement of the cavity 20. During the product reaction process, the limiting assembly 30 is provided so that the cavity 20 cannot move in its axial and / or radial directions, thereby maintaining the stability between the cavity 20 and the furnace body 10. The number of limiting assemblies 30 includes but is not limited to one, two, three, five, ten, etc.

[0037] Therefore, by providing the limiting assembly 30 , the movement of the cavity 20 in two directions relative to the furnace body 10 is limited, thereby reducing the risk of the cavity 20 being broken and increasing the service life of the processing device.

[0038] In one embodiment, the diameter of the cavity 20 becomes larger at the opening position, that is, the diameter of the extension portion 21 is larger than the diameter of the cavity 20 inside the furnace body 10. The size of the extension portion 21 corresponds to the size of the furnace door 11. The cavity 20 and the furnace door 11 are sealed by a sealing ring to form a closed space inside the cavity 20. A heat insulating member 13 is provided on the side of the furnace door 11 facing the cavity 20. The size of the heat insulating member 13 corresponds to the size of the extension portion 21. When the furnace door 11 is closed, the heat insulating member 13 fills the space of the extension portion 21. The heat insulating member 13 includes but is not limited to heat insulating materials, heat reflecting plates, etc. The heat insulating member 13 can reduce the heat loss of the cavity 20 and maintain the temperature inside the cavity 20 stable.

[0039] The furnace door 11 may be made of, but is not limited to, metal, quartz, or the like. The furnace door 11 may be made of metal, and its surface may be plated with a corrosion-resistant material such as nickel or Teflon as needed. Alternatively, the furnace door 11 may be made of metal and equipped with a reflective heat-insulating member 13. This arrangement enhances the structural strength of the furnace door 11 while also shielding the furnace door 11 from process gases and heat radiation.

[0040] In one embodiment, the processing device includes an air blow pipe (not shown) disposed on the furnace door 11. The air blow pipe is used to purge protective gas into the gap between the furnace door 11 and the chamber 20. This can reduce the impact of the process reaction gases in the chamber 20 on the furnace door 11 and other related structures. The protective gas is a gas that is harmless to the furnace door 11, such as nitrogen.

[0041] In one embodiment, a raised portion 22 is formed on the outer circumference of the extension portion 21. A stopper assembly 30 is disposed on the raised portion 22 to restrict movement of the chamber 20 relative to the furnace body 10 in both directions, reducing the risk of breakage of the chamber 20 and increasing the service life of the processing device. The raised portion 22 is fixed or integrally formed on the outer side of the extension portion 21.

[0042] In a specific embodiment, a continuous protrusion 22 is provided on the outer peripheral surface of the extension portion 21. A plurality of limiting components 30 are spaced apart and distributed on the protrusion 22. In this embodiment, there are eight limiting components 30.

[0043] In one embodiment, a plurality of protrusions 22 are spaced apart on the outer circumference of the extension portion 21. The number of the limiting components 30 corresponds to the number of the protrusions 22. The plurality of protrusions 22 and the corresponding limiting components 30 are spaced apart and distributed on the outer circumference of the extension portion 21.

[0044] The above-mentioned limit assembly 30 is disposed on the protrusion 22. The limit assembly 30 can be a whole unit, and a recess is provided on the side of the limit assembly 30 facing the protrusion 22, so that the limit assembly 30 clamps the protrusion 22. The limit assembly 30 can also be two limit blocks disposed opposite to each other, and the two limit blocks are fixedly connected, so that the limit assembly 30 clamps the protrusion 22.

[0045] In one embodiment, please refer to Figure 3, which is a schematic diagram of the structure of the limit assembly in one embodiment of the processing device of the present application. In conjunction with Figures 1 and 2, the processing device includes a base plate 12. The base plate 12 is mounted on the outer periphery of the extension portion 21. The base plate 12 is located between the furnace body 10 and the raised portion 22. The cavity 20 is fixed relative to the base plate 12. The base plate 12 is used to support the cavity 20. Connection methods include but are not limited to screwing, clamping, bonding, etc.

[0046] In one embodiment, the limiting assembly 30 includes a first limiting block 31 and a second limiting block 32. The first limiting block 31 is provided on the base plate 12. The first limiting block 31 is provided on a side of the protrusion 22 facing the base plate 12. The second limiting block 32 and the first limiting block 31 are used to clamp the protrusion 22. The second limiting block 32 is provided on a side of the protrusion 22 away from the base plate 12. The positions of the first limiting block 31 and the second limiting block 32 correspond to each other. The second limiting block 32 is fixedly arranged relative to the first limiting block 31. The protrusion 22 is clamped between the first limiting block 31 and the second limiting block 32, so that the first limiting block 31 and the second limiting block 32 clamp the protrusion 22.

[0047] By clamping the protrusion 22 with the first and second limiting blocks 31 and 32, the protrusion 22 is restricted from moving in the first and second directions D1 and D2, thereby restricting movement of the cavity 20 relative to the furnace body 10 in both directions. The first direction D1 is from the furnace tail to the furnace mouth of the furnace body 10, and the second direction D2 is from the furnace mouth to the furnace tail of the furnace body 10.

[0048] The first limiting block 31 can be detachably or fixedly connected to the bottom plate 12. The second limiting block 32 can be detachably or fixedly connected to the first limiting block 31.

[0049] In one embodiment, the limiting assembly 30 includes an adjustment member 33. The adjustment member 33 is disposed between the first limiting block 31 and the second limiting block 32 and is capable of defining the relative distance between the first limiting block 31 and the second limiting block 32. Furthermore, the adjustment member 33 adjusts the relative distance between the second limiting block 32 and the first limiting block 31, allowing for adaptability to different protrusions 22 to meet varying usage requirements.

[0050] The above-mentioned adjusting member 33 is arranged between the first limit block 31 and the second limit block 32 on a side away from the protrusion 22. That is, the adjusting member 33 is arranged above the protrusion 22. In a specific embodiment, the first limit block 31 and the second limit block 32 are both provided with through holes. The adjusting member 33 includes but is not limited to a tightening screw, a tensioning screw, etc. The adjusting member 33 passes through the through hole. The relative distance between the first limit block 31 and the second limit block 32 is adjusted according to the width of the protrusion 22. The adjusting member 33 may pass through the through hole on the second limit block 32 so that the second limit block 32 is fixedly connected to the first limit block 31. The adjusting member 33 may also pass through the through holes on the first limit block 31 and the second limit block 32 so that the base plate 12, the first limit block 31 and the second limit block 32 are fixedly connected.

[0051] In one embodiment, the adjusting member 33 may be an elastic member. The adjusting member 33 is disposed between the first limit block 31 and the second limit block 32. The adjusting member 33 can change the stretching distance according to the width of the protrusion 22, thereby adjusting the relative distance between the first limit block 31 and the second limit block 32.

[0052] In one embodiment, the limiting assembly 30 includes a guide block 34. The guide block 34 serves as a guide. One end of the guide block 34 is disposed on the base plate 12 and / or the first limiting block 31. The second limiting block 32 defines a guide hole 321, and the other end of the guide block 34 is penetrated by a guide hole 321.

[0053] Specifically, the guide block 34 is fixedly connected to the base plate 12 and / or the first limit block 31. The connection methods include but are not limited to screwing, bonding, clamping, etc. The second limit block 32 is sleeved on the guide block 34 through the guide hole 321. The second limit block 32 moves on the guide block 34 to adjust the relative distance between the first limit block 31 and the second limit block 32. At the same time, the guide block 34 is provided with a guide hole 321, which can fix the relative position between the second limit block 32 and the base plate 12 and / or the first limit block 31, reducing the possibility of displacement of the first limit block 31 and the second limit block 32.

[0054] In one embodiment, a threaded hole is provided in the guide block 34 , through which a bolt passes to fix the positions of the guide block 34 , the first limiting block 31 , and the base plate 12 .

[0055] In one embodiment, the limiting assembly 30 includes a first soft pad 35 and a second soft pad 36. The first soft pad 35 is disposed between the first limiting block 31 and the protrusion 22. The first soft pad 35 flexibly contacts the protrusion 22. The first soft pad 35 can be disposed on a side of the first limiting block 31 facing the protrusion 22. The first soft pad 35 is fixedly or detachably connected to the first limiting block 31. The first soft pad 35 can also be disposed on a side of the protrusion 22 facing the first limiting block 31. The first soft pad 35 is fixedly or detachably connected to the side of the protrusion 22 facing the first limiting block 31.

[0056] The second soft pad 36 is disposed between the second stopper 32 and the raised portion 22. The second soft pad 36 flexibly contacts the raised portion 22. The second soft pad 36 can be disposed on the side of the second stopper 32 facing the raised portion 22. The second soft pad 36 is fixedly or detachably connected to the second stopper 32. The second soft pad 36 can also be disposed on the side of the raised portion 22 facing the second stopper 32. The second soft pad 36 is fixedly or detachably connected to the side of the raised portion 22 facing the second stopper 32.

[0057] The first soft pad 35 and the second soft pad 36 have the property of being resistant to high temperatures and can be made of flexible materials.

[0058] By arranging a first soft pad 35 between the first limit block 31 and the raised portion 22, and a second soft pad 36 between the second limit block 32 and the raised portion 22, the hard contact between the cavity 20 and the limit assembly 30 can be reduced, and the possibility of damage to the extension portion 21 can be reduced; the friction force can be enhanced, and the problem of loose connection between the limit assembly 30 and the raised portion 22 can be reduced.

[0059] In one embodiment, there are at least two position-limiting assemblies 30. The number of position-limiting assemblies 30 includes, but is not limited to, two, three, four, five, seven, ten, fifteen, etc. At least two position-limiting assemblies 30 are independently used for the cavity 20. The multiple position-limiting assemblies 30 are independently provided and are not interconnected. Each position-limiting assembly 30 can independently limit the cavity 20.

[0060] In one embodiment, the extension portion 21 is tubular. The outer circumferential surface of the extension portion 21 is raised to form a raised portion 22. Stopper assemblies 30 are circumferentially spaced apart on the outer circumferential surface of the extension portion 21. Multiple stopper assemblies 30 are circumferentially distributed around the central axis of the raised portion 22, thereby evenly distributing the clamping force of the stopper assemblies 30 around the outer circumference of the cavity 20.

[0061] Providing a full ring of stopper assemblies 30 on the outer circumference of the extension 21 hinders heat dissipation from the opening of the furnace body 10. Providing a full ring of stopper assemblies 30 requires additional cooling structures, such as water cooling pipes within the full ring of stopper assemblies 30. This complex structure requires additional structures such as sealing rings, increasing operational complexity and manufacturing costs.

[0062] Multiple limiting components 30 are arranged at intervals on the outer peripheral surface of the extension part 21. Compared with the limiting components 30 arranged on the outer peripheral surface of the extension part 21 in a full circle, the structure is simple, heat dissipation is easy, and material and processing costs are saved.

[0063] When the protrusion 22 is a whole, the protrusion 22 is annularly arranged on the outer peripheral surface of the extension portion 21. When there are multiple protrusions 22, the multiple protrusions 22 are spaced apart and arranged on the outer peripheral surface of the extension portion 21.

[0064] In other embodiments, other auxiliary limiting members may be provided, such as an annular limiting member 14 provided between the furnace body 10 and the cavity 20 . The annular limiting member 14 can both limit the movement of the cavity 20 and support the weight of the cavity 20 .

[0065] In one embodiment, please refer to Figure 4, which is a schematic diagram of the support assembly structure of one embodiment of the processing device of the present application. In conjunction with Figures 1 and 2, the processing device includes a base plate 12. Base plate 12 is sleeved around the outer periphery of extension portion 21. Base plate 12 is located between furnace body 10 and raised portion 22. Base plate 12 supports cavity 20. Connection methods include, but are not limited to, screwing, clamping, and bonding.

[0066] The processing device also includes a support assembly 40. The support assembly 40 is disposed on the bottom plate 12 and supports the outer circumference of the raised portion 22 upward. The support assembly 40 contacts the outer circumference of the raised portion 22 and is disposed below the raised portion 22 to support the weight of the cavity 20, thereby reducing the risk of the cavity 20 sinking and causing it to break. The number of support assemblies 40 includes, but is not limited to, one, two, three, five, eight, ten, etc.

[0067] Since the thickness of the protrusion 22 is thicker than that of the extension portion 21 , the outer peripheral surface of the protrusion 22 supported by the support assembly 40 is less likely to cause the cavity 20 to break.

[0068] Limiting assemblies 30 are set at intervals on the outer periphery of the protrusion 22 to clamp the protrusion 22, and supporting assemblies 40 are used to support the protrusion 22 below the protrusion 22. This can reduce the movement of the cavity 20 in two directions while increasing support for the cavity 20 and reducing the risk of the cavity 20 being broken.

[0069] In the present application, eight stopper assemblies 30 are evenly spaced around the outer circumference of the protrusion 22, and the stopper assemblies 30 clamp the protrusion 22. Two support assemblies 40 are disposed below the protrusion 22 to support the protrusion 22. In other embodiments, two stopper assemblies 30 may be spaced apart around the outer circumference of the protrusion 22, and one support assembly 40 may be disposed below the protrusion 22. In actual use, this arrangement may be adjusted based on actual conditions.

[0070] In one embodiment, the support assembly 40 includes a positioning block 41, a support block 42, a first fixing member 43 and a second fixing member 44. The positioning block 41 is arranged on the base plate 12. The connection method includes but is not limited to screwing, clamping, bonding, etc. The positioning block 41 supports the outer peripheral surface of the protrusion 22 upward. The support block 42 is formed with an extension hole 46, and the extension direction of the extension hole 46 is perpendicular to the outer peripheral surface of the protrusion 22. The support block 42 is arranged between the positioning block 41 and the protrusion 22, thereby supporting the protrusion 22. The surface of the support block 42 facing the protrusion 22 is in contact with the protrusion 22, which can provide better supporting force to the protrusion 22.

[0071] A first fixing member 43 is disposed on the base plate 12 and is provided with an extension hole 46. Passing through the extension hole 46, the first fixing member 43 secures the support block 42 to the base plate 12, creating a greater frictional force between the support block 42 and the base plate 12, thereby better supporting the weight of the cavity 20. Furthermore, the provision of the extension hole 46 allows the support block 42 to move freely within a certain range. Adjusting the distance between the support block 42 and the positioning block 41 allows the support block 42 to mate with the protrusion 22, thereby accommodating protrusions 22 of varying sizes. The range of movement of the support block 42 is the length of the extension hole 46 extending perpendicularly to the outer circumference of the protrusion 22.

[0072] The second fixing member 44 sequentially passes through the positioning block 41 and the support block 42 and abuts against the first fixing member 43. The second fixing member 44 can fix the relative position between the support member and the positioning block 41, and at the same time provide a certain supporting force to the first fixing member 43.

[0073] In the above manner, the support assembly 40 can better support the weight of the cavity 20. At the same time, the support block 42 moves within a certain range and can match cavities 20 of different sizes, so that the support assembly 40 has both strong supporting capabilities and good flexibility.

[0074] In one embodiment, the support assembly 40 includes a support pad 45. The support pad 45 is disposed between the support block 42 and the outer surface of the raised portion 22. The support pad 45 is in flexible contact with the outer surface of the raised portion 22. Providing the support pad 45 on the side of the support block 42 facing the outer surface of the raised portion 22 reduces hard contact between the support block 42 and the raised portion 22, reducing the possibility of damage to the extension portion 21. It also enhances friction and reduces the possibility of loosening the connection between the support block 42 and the raised portion 22.

[0075] The support pad 45 can be disposed on the side of the support block 42 facing the outer surface of the raised portion 22. The support pad 45 is fixedly connected to the support block 42, including but not limited to bonding, clamping, or integral molding. The support pad 45 can also be disposed on the outer surface of the raised portion 22. The support pad 45 is fixedly connected to the raised portion 22, including but not limited to bonding, clamping, or integral molding. The support pad 45 is high-temperature resistant and can be made of a flexible material.

[0076] In one embodiment, the limiting assembly 30 moves relative to the base plate 12. The movement of the limiting assembly 30 relative to the base plate 12 can refer to the movement of the support block 42 in the support assembly 40 described above.

[0077] Specifically, a support assembly 40 is placed between the first limit block 31 and the second limit block 32. The positioning block 41 is placed between the first limit block 31 and the second limit block 32. The positioning block 41 is detachably connected or integrally formed with the side of the first limit block 31 or the second limit block 32 away from the protrusion 22, so that the first limit block 31 and the second limit block 32 can clamp the protrusion 22 and play a role in limiting the protrusion 22. Extension holes 46 are provided on the first limit block 31, the support block 42, and the second limit block 32. The first fixing member 43 passes through the first limit block 31, the support block 42, the second limit block 32, and the bottom plate 12 in sequence and is fixed to the bottom plate 12. The support block 42 contacts the protrusion 22, thereby playing a supporting role for the protrusion 22. At the same time, due to the provision of the extension hole 46, the support block 42 can move freely within a certain range. By adjusting the distance between the support block 42 and the positioning block 41, the support block 42 can be aligned with the protrusion 22, so that the position of the limit assembly 30 can be adjusted relative to the bottom plate 12 and support the protrusion 22. This design can not only limit the movement of the cavity 20 in both directions, but also provide support for the cavity 20.

[0078] Referring to Figures 1 to 3, the present application provides a limiting assembly 30. The limiting assembly 30 includes a first limiting block 31 and a second limiting block 32. The first limiting block 31 is arranged on the bottom plate 12 in the processing device. The bottom plate 12 is sleeved on the outer periphery of the extension portion 21 on the cavity 20 of the processing device. The bottom plate 12 is located between the furnace body 10 of the processing device and the part to be fixed. The bottom plate 12 is used to support the cavity 20. The connection method includes but is not limited to screwing, clamping, bonding, etc. The first limiting block 31 is arranged on the side of the part to be fixed facing the bottom plate 12. The second limiting block 32 and the first limiting block 31 are used to clamp the part to be fixed. The part to be fixed can be the protrusion 22 protruding from the outer peripheral surface of the extension portion 21 mentioned above. The second limiting block 32 is arranged on the side of the part to be fixed away from the bottom plate 12. The positions of the first limiting block 31 and the second limiting block 32 correspond to each other. The second limiting block 32 is fixed relative to the first limiting block 31. The piece to be fixed is clamped between the first limiting block 31 and the second limiting block 32 , so that the first limiting block 31 and the second limiting block 32 clamp the piece to be fixed.

[0079] By clamping the fixture with the first and second stoppers 31 and 32, movement of the fixture in the first and second directions D1 and D2 can be restricted, thereby limiting movement of the chamber 20 relative to the furnace body 10 in both directions. The first direction D1 is from the furnace tail to the furnace mouth of the furnace body 10. The second direction D2 is from the furnace mouth to the furnace tail of the furnace body 10.

[0080] The first limiting block 31 can be detachably or fixedly connected to the bottom plate 12. The second limiting block 32 can be detachably or fixedly connected to the first limiting block 31.

[0081] In one embodiment, the limiting assembly 30 further includes an adjustment member 33. The adjustment member 33 is disposed between the first limiting block 31 and the second limiting block 32 and is capable of defining the relative distance between the first limiting block 31 and the second limiting block 32. Furthermore, the adjustment member 33 adjusts the relative distance between the second limiting block 32 and the first limiting block 31, adapting to different fixed parts and meeting different usage requirements.

[0082] The above-mentioned adjusting member 33 is arranged between the first limit block 31 and the second limit block 32 on a side away from the part to be fixed.

The adjusting member 33 includes but is not limited to a tightening screw, a tensioning screw, etc. The adjusting member 33 passes through the through hole. The relative distance between the first limit block 31 and the second limit block 32 is adjusted according to the width of the part to be fixed. The adjusting member 33 may pass through the through hole on the second limit block 32 so that the second limit block 32 is fixedly connected to the first limit block 31. The adjusting member 33 may also pass through the through holes on the first limit block 31 and the second limit block 32 so that the base plate 12, the first limit block 31 and the second limit block 32 are fixedly connected.

[0083] In one embodiment, the adjusting member 33 may be an elastic member. The adjusting member 33 is disposed between the first limiting block 31 and the second limiting block 32. The adjusting member 33 can change the stretching distance according to the width of the component to be fixed, thereby adjusting the relative distance between the first limiting block 31 and the second limiting block 32.

[0084] In one embodiment, the limiting assembly 30 includes a guide block 34. The guide block 34 serves as a guide. One end of the guide block 34 is disposed on the base plate 12 and / or the first limiting block 31. The second limiting block 32 defines a guide hole 321, and the other end of the guide block 34 is penetrated by a guide hole 321.

[0085] Specifically, the guide block 34 is fixedly connected to the base plate 12 and / or the first limit block 31. The connection methods include but are not limited to screwing, bonding, clamping, etc. The second limit block 32 is sleeved on the guide block 34 through the guide hole 321. The second limit block 32 moves on the guide block 34 to adjust the relative distance between the first limit block 31 and the second limit block 32. At the same time, the guide block 34 is provided with a guide hole 321, which can fix the relative position between the second limit block 32 and the base plate 12 and / or the first limit block 31, reducing the possibility of displacement of the first limit block 31 and the second limit block 32.

[0086] In one embodiment, a threaded hole is provided in the guide block 34 , through which a bolt passes to fix the positions of the guide block 34 , the first limiting block 31 , and the base plate 12 .

[0087] In one embodiment, the limiting assembly 30 includes a first soft pad 35 and a second soft pad 36. The first soft pad 35 is disposed between the first limiting block 31 and the part to be fixed. The first soft pad 35 flexibly contacts the part to be fixed. The first soft pad 35 can be disposed on a side of the first limiting block 31 facing the part to be fixed. The first soft pad 35 is fixedly or detachably connected to the first limiting block 31. The first soft pad 35 can also be disposed on a side of the part to be fixed facing the first limiting block 31. The first soft pad 35 is fixedly or detachably connected to a side of the part to be fixed facing the first limiting block 31.

[0088] The second soft pad 36 is disposed between the second stopper 32 and the part to be secured. The second soft pad 36 flexibly contacts the part to be secured. The second soft pad 36 can be disposed on the side of the second stopper 32 facing the part to be secured. The second soft pad 36 is fixedly or removably connected to the second stopper 32. The second soft pad 36 can also be disposed on the side of the part to be secured facing the second stopper 32, and the second soft pad 36 is fixedly or removably connected to the side of the part to be secured facing the second stopper 32.

[0089] The first soft pad 35 and the second soft pad 36 have the property of being resistant to high temperatures and can be made of flexible materials.

[0090] By arranging a first soft pad 35 between the first limit block 31 and the part to be fixed, and arranging a second soft pad 36 between the second limit block 32 and the part to be fixed, the hard contact between the cavity 20 and the limit assembly 30 can be reduced, and the possibility of damage to the extension part 21 can be reduced; the friction force can be enhanced, and the problem of loose connection between the limit assembly 30 and the part to be fixed can be reduced.

[0091] In one embodiment, the limiting assembly 30 moves relative to the base plate 12. The movement of the limiting assembly 30 relative to the base plate 12 can refer to the movement of the support block 42 in the support assembly 40 described above.

[0092] Specifically, a support assembly 40 is placed between the first limit block 31 and the second limit block 32. The positioning block 41 is placed between the first limit block 31 and the second limit block 32. The positioning block 41 is detachably connected or integrally formed with the side of the first limit block 31 or the second limit block 32 away from the protrusion 22, so that the first limit block 31 and the second limit block 32 can clamp the protrusion 22 and play a role in limiting the protrusion 22. Extension holes 46 are provided on the first limit block 31, the support block 42, and the second limit block 32. The first fixing member 43 passes through the first limit block 31, the support block 42, the second limit block 32, and the bottom plate 12 in sequence and is fixed to the bottom plate 12. The support block 42 contacts the protrusion 22, thereby playing a supporting role for the protrusion 22. At the same time, due to the provision of the extension hole 46, the support block 42 can move freely within a certain range. By adjusting the distance between the support block 42 and the positioning block 41, the support block 42 can be aligned with the protrusion 22, so that the position of the limit assembly 30 can be adjusted relative to the bottom plate 12 and support the protrusion 22. This design can not only limit the movement of the cavity 20 in both directions, but also provide support for the cavity 20.

[0093] This application provides a method for using a processing device. This method employs the aforementioned processing device. The processing devices described in the aforementioned embodiments will not be described in detail here. The method for using this application will be described using a diffusion furnace as an example.

[0094] S101 . The limiting assembly 30 includes a first limiting block 31 and a second limiting block 32 , and the first limiting block 31 and the second limiting block 32 are clamped on the extension portion 21 .

[0095] Specifically, the outer peripheral surface of the extension portion 21 is raised to form a raised portion 22. First, the first limit block 31 is fixed between the base plate 12 and the raised portion 22. Secondly, a bolt is used to pass through the through hole of the guide block 34 to fix the guide block 34, the first limit block 31 and the base plate 12. Then the guide block 34 is penetrated by the guide hole 321 of the second limit block 32, so that the first limit block 31 and the second limit block 32 are relatively fixed. Then the adjustment member 33 is used to adjust the relative distance between the second limit block 32 and the first limit block 31, and the first limit block 31 and the second limit block 32 clamp the raised portion 22. Among them, a first soft pad 35 is provided between the first limit block 31 and the raised portion 22, and a second soft pad 36 is provided between the second limit block 32 and the raised portion 22, so that the limit assembly 30 clamps the raised portion 22 to limit the movement of the cavity 20 in two directions relative to the furnace body 10.

[0096] S102 . The supporting assembly 40 supports the outer peripheral surface of the extension portion 21 upward.

[0097] Specifically, when using support assembly 40, first adjust the distance between support block 42 and protrusion 22. Next, insert first fixing member 43 through extension hole 46 to secure support block 42 to bottom plate 12. Then, insert second fixing member 44 through positioning block 41 and support block 42 in sequence, so that second fixing member 44 abuts first fixing member 43, thereby enabling support assembly 40 to support the weight of cavity 20.

[0098] Limiting assemblies 30 are set at intervals on the outer periphery of the protrusion 22 to clamp the protrusion 22, and supporting assemblies 40 are used to support the protrusion 22 below the protrusion 22. This can reduce the movement of the cavity 20 in two directions while increasing support for the cavity 20 and reducing the risk of the cavity 20 being broken.
