For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] The annealing equipment provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0049] like Figures 1 to 4 As shown, the annealing equipment according to some embodiments of the present application includes: an equipment main body 100 and a dust collecting mechanism 200; an inlet 101 is provided in the equipment main body 100, and the inlet 101 is used for allowing the workpiece 300 to pass through to enter the equipment main body 100; the dust collecting mechanism 200 can be detachably installed on the equipment main body 100, and at least partially extends into the inlet 101, and is used to receive crystalline impurities that fall off the top wall of the inlet 101.

[0050] In the embodiment of the present application, a detachable dust collecting mechanism 200 is provided at the inlet 101 of the device body 100, and the dust collecting mechanism 200 at least partially extends into the inlet 101, so that the dust collecting mechanism 200 can be used to receive the crystallized impurities that fall off the top wall of the inlet 101, thereby preventing the crystallized impurities from falling onto the workpiece 300 and causing contamination of the workpiece 300. At the same time, when cleaning is required, the dust collecting mechanism 200 only needs to be disassembled as a whole for cleaning, which is convenient for cleaning and maintenance and has low use cost, and also avoids the impact of the need to stop the machine for cleaning on the operating efficiency of the equipment.

[0051] It should be noted that the annealing equipment in the embodiment of the present application can be used to perform high-temperature annealing operations on the target workpiece 300. Specifically, the annealing equipment can be applied to the production and preparation process of photovoltaic modules, and the workpiece 300 can be a battery cell. Usually, in the production process of photovoltaic modules, the battery cell needs to be processed by diffusion, advancement, annealing and other processes. The annealing equipment in the embodiment of the present application can be applied to the annealing process of the battery cell to perform heat treatment on the battery cell and improve the structural stability of the battery cell.

[0052] Specifically, the annealing device includes an equipment body 100 , in which a process chamber is disposed. An inlet 101 is disposed on the equipment body 100 , and the inlet 101 is connected to the process chamber. The workpiece 300 can be sent into the process chamber through the inlet 101 for high-temperature annealing treatment.

[0053] Furthermore, a dust collecting mechanism 200 is installed on the device body 100 at a position close to the outside of the inlet 101, and the dust collecting mechanism 200 is at least partially extended into the inlet 101, so that the dust collecting mechanism 200 can be used to collect crystallized impurities that fall off from the top wall of the inlet 101. The part of the dust collecting mechanism 200 located in the inlet 101 can be arranged close to the top wall of the inlet 101, so as not to affect the workpiece 300 from entering the device body 100 from below the dust collecting mechanism 200.

[0054] It is understandable that in the existing annealing process, after the annealing equipment has been used for a period of time, crystals will be generated at the entrance 101 of the annealing equipment. As the crystals continue to accumulate, some of the crystals will fall off the workpiece 300 produced, causing contamination of the workpiece 300. After research, it was found that the main reason for the occurrence of crystals is that when the workpiece 300 passes through the previous diffusion process, residues such as metaphosphoric acid or phosphorus pentoxide will remain on the surface of the workpiece 300. When the workpiece 300 enters the annealing equipment, due to the high temperature in the annealing equipment (the temperature is as high as about 720°C), the residues on the workpiece 300 will be vaporized, and then crystallized and deposited on the top wall of the entrance 101 of the annealing equipment. The location of the crystals is often close to the center of the top wall of the entrance 101. Due to the high temperature of the annealing equipment, it is necessary to stop the machine for cooling during cleaning, which seriously affects the efficiency of the equipment; and due to the limitation of the structural space at the entrance 101, it is difficult to clean and it is also difficult to clean.

[0055] To this end, in the embodiment of the present application, a dust collecting mechanism 200 is provided at the inlet 101 of the equipment body 100, so that the dust collecting mechanism 200 at least partially extends into the inlet 101, so that the dust collecting mechanism 200 can be used to collect the crystallized impurities that fall off the top wall of the inlet 101. When cleaning is required, the dust collecting mechanism 200 only needs to be taken out as a whole for replacement or cleaning, which is convenient and efficient to operate, and can also avoid the shutdown of the annealing equipment, which helps to improve production efficiency.

[0056] Alternatively, if Figure 2 As shown, the annealing equipment further includes a conveying member 120 , which is rotatably connected to the support frame 110 and is used to convey the workpiece 300 to the equipment body 100 through the entrance 101 , and there is a gap between the dust collecting mechanism 200 and the conveying member 120 .

[0057] In the embodiment of the present application, a conveyor 120 is provided in the support frame 110 so that the workpiece 300 can be sent into the process chamber of the equipment body 100 through the inlet 101 by the conveyor 120 to perform a high temperature annealing operation. At the same time, a gap is provided between the dust collecting mechanism 200 and the conveyor 120 so that when the workpiece 300 passes through the inlet 101, the dust collecting mechanism 200 is prevented from interfering with the workpiece 300.

[0058] It should be noted that the size of the gap between the dust collecting mechanism 200 and the conveying member 120 can be determined according to the structural dimensions of the inlet 101 and the structural dimensions of the workpiece 300. Those skilled in the art can flexibly set it and no limitation is made here.

[0059] The conveying member 120 may include a plurality of conveying wheels, which are rotatably connected to the support frame 110 respectively, and are arranged in parallel and spaced apart along the first direction X, so that the workpiece 300 can be conveyed by the rotational cooperation of the plurality of conveying wheels.

[0060] Alternatively, if Figure 2 and Figure 4 As shown, the dust collecting mechanism 200 includes: a fixing member 210 and a dust collecting assembly 220; a support frame 110 is provided on the device body 100, the support frame 110 is provided outside the inlet 101, and the fixing member 210 is detachably connected to the support frame 110; one end of the dust collecting assembly 220 is connected to the fixing member 210, and the other end extends into the inlet 101. Optionally, the fixing member 210 is slidably supported on the support frame 110.

[0061] In the embodiment of the present application, one end of the dust receiving assembly 220 is connected to the fixing member 210, and the other end of the dust receiving assembly 220 extends into the inlet 101, and the crystalline impurities falling off the top wall of the inlet 101 can be received through the dust receiving assembly 220. At the same time, the fixing member 210 is detachably connected to the support frame 110 of the device body 100, so that the dust receiving mechanism 200 can be taken out by disassembling the fixing member 210 without affecting the operation of the device, and then the dust receiving mechanism 200 can be cleaned and maintained.

[0062] Furthermore, a fixing member 210 is provided to be slidably supported on the support frame 110 so that the dust collecting mechanism 200 as a whole can slide on the support frame 110, so that the position of the dust collecting mechanism 200 at the entrance 101 can be adjusted by pushing and pulling the dust collecting mechanism 200, which is convenient for actual operation.

[0063] Specifically, support frames 110 are provided on both sides of the inlet 101 of the equipment body 100, and the fixing parts 210 in the dust collecting mechanism 200 are installed on the support frames 110. The fixing parts 210 and the support frames 110 are detachably matched, for example, they can be matched by snap-fitting, plug-in, etc. Of course, other matching methods can also be selected, and the embodiments of the present application are not limited to this.

[0064] Among them, the fixing member 210 can be made of a rigid material to ensure that the fixing member 210 has a certain structural strength and plays a connecting and supporting role with the dust receiving assembly 220. For example, the fixing member 210 can be made of a metal profile. In addition, a certain counterweight can be set for the fixing member 210 so that the fixing member 210 can be stably supported on the support frame 110 to avoid the fixing member 210 from turning over during use. The specific structure and material of the fixing member 201 can be flexibly set according to actual needs, and the embodiment of the present application is not limited to this. Furthermore, the weight of the fixing member 210 is greater than the weight of the dust receiving assembly 220.

[0065] In some embodiments, the fixing member 210 can be set to be a long strip shape. For example, the fixing member 201 can be made of a columnar metal profile. The extension direction of the fixing member 210 intersects with the extension direction of the support frame 110. The two ends of the fixing member 210 are respectively slidably supported on the support frame 110. The fixing member 210 and the support frame 110 can adopt a cross-lap matching structure.

[0066] Among them, the lower surface of the fixing member 210 can be set as a plane, and correspondingly, the upper surface of the support frame 110 is also set as a plane, and the fixing member 210 and the support frame 110 cooperate through the plane to stably support the fixing member 210 on the support frame 110. In this way, by smoothly moving the fixing member 210, the dust receiving assembly 220 can be pushed into the inlet 101, or the dust receiving assembly 220 can be pulled out from the inlet 101, which can save effort during operation. In addition, the fixing member 210 and the support frame 110 cooperate through the plane, which facilitates the flexible movement of the fixing member 210 to adjust the position of the dust receiving assembly 220 in the inlet 101.

[0067] In other embodiments, a slide groove may be provided on the lower surface of the fixing member 210 along the direction of the support frame, and the support frame 110 may be at least partially slidably engaged in the slide groove. The fixing member 210 may slide on the support frame 110, and the slide groove may play a limiting role, thereby improving the smoothness of the sliding process of the fixing member 210.

[0068] In specific applications, such as Figure 2 As shown, the connection direction of the two support frames 110 is the third direction Z. Along the third direction Z, the distance between the two support frames 110 is greater than the width of the entrance 101 along the third direction Z to avoid the support frames 110 blocking the entrance 101.

[0069] Furthermore, the dimension of the fixing member 210 along the third direction Z is set to be larger than the spacing between the two support frames 110, so that the two ends of the fixing member 210 can be respectively mounted on the support frames 110. In addition, the dimension of the dust receiving assembly 220 along the third direction Z is set to be smaller than the width of the inlet 101 along the third direction Z, so that the dust receiving assembly 220 can freely enter and exit the inlet 101.

[0070] Alternatively, if Figure 4 As shown, a material stopper 221 is provided at one end of the dust receiving assembly 220 extending into the inlet 101, and the material stopper 221 extends from the dust receiving assembly 220 toward the top wall of the inlet 101. In the embodiment of the present application, the material stopper 221 is provided at one end of the dust receiving assembly 220 extending into the inlet 101, and the material stopper 221 extends toward the top wall of the inlet 101, so that when the dust receiving mechanism 200 is disassembled and cleaned, the material stopper 221 can play a certain blocking role for the impurities received in the dust receiving assembly 220, so as to prevent the impurities from falling from the rear edge of the dust receiving assembly 220 during the movement of the dust receiving mechanism 200.

[0071] It can be understood that the side of the top wall of the dust receiving component 220 facing the entrance 101 is the dust receiving surface, and impurities falling off from the top wall of the entrance 101 will fall on the dust receiving surface. When the dust receiving mechanism 200 is taken out from the entrance 101, there is a risk that the impurities on the dust receiving surface will fall from the edge of the dust receiving component 220. Therefore, by providing a blocking portion 221 at one end of the dust receiving component 220 extending into the entrance 101, impurities on the dust receiving surface can be prevented from falling.

[0072] It should be noted that the material blocking portion 221 and the dust collecting assembly 220 may adopt an integrally formed structure or a split-formed structure, and those skilled in the art may flexibly configure them according to actual needs, which is not limited in the embodiments of the present application.

[0073] Alternatively, if Figure 4 As shown, the dust receiving assembly 220 may include a first dust receiving plate 2201 and a second dust receiving plate 2202 connected to each other, one end of the second dust receiving plate 2202 away from the first dust receiving plate 2201 faces the inlet 101, and the end of the second dust receiving plate 2202 is bent toward the top wall to form a material blocking portion 221. In the embodiment of the present application, by bending the end of the second dust receiving plate 2202 to form the material blocking portion 221, the material blocking portion 221 and the second dust receiving plate 2202 form an integrated structure, which is convenient for actual processing and manufacturing.

[0074] Alternatively, if Figure 4 As shown, the angle A between the material blocking portion 221 and the dust receiving assembly 220 satisfies: 10°≤A≤170°. Preferably, the angle A can be set to 135°.

[0075] In the embodiment of the present application, a value range of the angle A between the material blocking portion 221 and the dust receiving assembly 220 is set to ensure that the material blocking portion 221 can form a blocking effect on impurities on the dust receiving assembly 220.

[0076] Exemplarily, the angle A between the material blocking portion 221 and the dust collecting assembly 220 can be set to any angle such as 10°, 30°, 75°, 90°, 100°, 110°, 120°, 125°, 130°, 135°, 140°, 150°, 170°, or a range between any two angles.

[0077] In some embodiments, the portion where the material blocking portion 221 and the dust receiving assembly 220 meet can be set as an arc transition structure to facilitate the cleaning of impurities at the junction of the material blocking portion 221 and the dust receiving assembly 220.

[0078] Alternatively, if Figure 4 and Figure 5 As shown, the fixing member 210 has an upper horizontal surface 211 and a vertical surface 212, and at least one of the upper horizontal surface 211 and the vertical surface 212 is provided with an adapting groove 213; the dust collecting component 220 is provided with an L-shaped connecting portion 222 at one end facing the fixing member 210, and the connecting portion 222 is provided with a mounting hole 22210 at a position corresponding to the adapting groove 213.

[0079] In the embodiment of the present application, the dust collecting assembly 220 is installed and fixed via the mounting hole 22210 in the connecting portion 222 and the adapting groove 213 on the fixing member 210 , thereby realizing a detachable connection between the dust collecting assembly 220 and the fixing member 210 .

[0080] In a specific application, the adapter groove 213 can be set as a T-shaped adapter groove, and the annealing equipment also includes a T-shaped nut and a bolt. During installation, the T-shaped nut (not shown in the figure) is inserted into the adapter groove 213, and then a bolt (not shown in the figure) is used to pass through the mounting hole 22210 in the connecting part 222 and connected to the T-shaped nut to install and fix the dust collecting assembly 220 on the fixing member 210.

[0081] Of course, other detachable connection methods may be used between the connecting portion 222 and the fixing member 210 , which may be flexibly arranged according to actual conditions, and are not limited in the embodiments of the present application.

[0082] Alternatively, if Figure 4 As shown, the adapting groove 213 can be set as a straight groove, and the extension direction of the straight groove is consistent with the extension direction of the fixing member 210, and both extend along the third direction Z, so that the position of the dust collecting component 220 along the third direction Z can be adjusted by adjusting the matching position of the mounting hole 22210 in the connecting part 222 and the adapting groove 213.

[0083] Alternatively, if Figure 4 As shown, the mounting hole 22210 can be set as a waist hole, and the extension direction of the waist hole intersects with the extension direction of the adapting groove 213 in the fixing member 201, and specifically can be cross-intersected.

[0084] Furthermore, during installation and use, the position of the dust collecting component 220 can be adjusted along the extension direction of the adapter groove 213, and the position of the dust collecting component 220 can also be adjusted along the extension direction of the mounting hole 22210, so that the position of the dust collecting component 220 can be adjusted along different directions, so as to adjust the dust collecting component 220 to a suitable position in the inlet 101.

[0085] Alternatively, if Figure 4 and Figure 5 As shown, the connecting portion 222 includes a first connecting portion 2221 cooperating with the upper horizontal surface 211, and a second connecting portion 2222 cooperating with the vertical surface 212; a first mounting hole 2221a extending along the first direction X is provided in the first connecting portion 2221, and a second mounting hole 2221b extending along the second direction Y is provided in the second connecting portion 2222; an adapting groove 213 extending along the third direction Z is provided in both the upper horizontal surface 211 and the vertical surface 212 of the fixing member 210.

[0086] Furthermore, the first connection portion 2221 is installed and matched with the adapting groove 213 in the upper horizontal surface 211 through the first installation hole 2221a, and the second connection portion 2222 is installed and matched with the adapting groove 213 in the vertical surface 212 through the second installation hole 2221b.

[0087] The first direction X is the direction in which the workpiece 300 enters and exits the entrance 101 , the second direction Y is the vertical direction, and the third direction Z is perpendicular to the first direction X and the second direction Y respectively.

[0088] In specific applications, the position of the dust collecting component 220 along the first direction X can be adjusted through the first mounting hole 2221a, the position of the dust collecting component 220 along the second direction Y can be adjusted through the second mounting hole 2221b, and the position of the dust collecting component 220 along the third direction Z can be adjusted through the adapter groove 213. In this way, the position of the dust collecting component 220 can be adjusted along three different dimensions to adapt to the application requirements of different scenarios.

[0089] In addition, the first mounting hole 2221a and the second mounting hole 2221b can be provided in plural, and the plural first mounting holes 2221a and the plural second mounting holes 2221b are arranged along the third direction Z at intervals.

[0090] Alternatively, if Figure 4As shown, the dust receiving assembly 220 includes: a first dust receiving plate 2201, a second dust receiving plate 2202 and an adjusting member 2203; the first dust receiving plate 2201 is connected to the fixing member 210, one end of the second dust receiving plate 2202 is connected to the first dust receiving plate 2201, and the other end of the second dust receiving plate 2202 extends into the inlet 101; the adjusting member 2203 is arranged between the first dust receiving plate 2201 and the second dust receiving plate 2202, and is used to adjust the relative position of the first dust receiving plate 2201 and the second dust receiving plate 2202, thereby adjusting the effective dust receiving area.

[0091] In an embodiment of the present application, a dust collecting component 220 is provided, which is composed of a first dust collecting plate 2201 and a second dust collecting plate 2202, and an adjusting member 2203 is provided between the first dust collecting plate 2201 and the second dust collecting plate 2202 to adjust the relative position of the first dust collecting plate 2201 and the second dust collecting plate 2202. Thus, the size of the part of the dust collecting component 220 extending into the inlet 101 can be flexibly adjusted according to the structure at the inlet 101, so as to better adapt to the structure at the inlet 101, so as to prevent crystallized impurities on the top wall of the inlet 101 from falling directly onto the workpiece 300.

[0092] Specifically, one end of the first dust receiving plate 2201 is connected to the fixing member 210, the other end of the first dust receiving plate 2201 extends toward the inlet 101, the second dust receiving plate 2202 is connected to the other end of the first dust receiving plate 2201, and one end of the second dust receiving plate 2202 away from the first dust receiving plate 2201 extends into the inlet 101. In addition, an adjusting member 2203 is provided between the first dust receiving plate 2201 and the second dust receiving plate 2202, and the length of the first dust receiving plate 2201 and the second dust receiving plate 2202 extending into the inlet 101 can be flexibly adjusted according to the structure at the inlet 101. In this way, through the cooperation of the first dust receiving plate 2201, the second dust receiving plate 2202 and the adjusting member 2203, the structure of the dust receiving assembly 220 can be flexibly adjusted according to the structure of the inlet 101, thereby ensuring that the crystallized impurities at the inlet 101 can be received by the dust receiving assembly 220.

[0093] In some examples, the first dust receiving plate 2201 and the second dust receiving plate 2202 can be made of metal plates, for example, aluminum alloy, stainless steel plates, etc., to ensure the strength and toughness of the first dust receiving plate 2201 and the second dust receiving plate 2202. In addition, the first dust receiving plate 210 and the second dust receiving plate 220 can be made of lightweight materials to reduce the overall weight of the dust receiving assembly 202. Of course, the first dust receiving plate 210 and the second dust receiving plate 220 can also be made of other materials, which is not limited in the present embodiment of the application.

[0094] The thickness of the first dust receiving plate 2201 and the second dust receiving plate 2202 can be set to: 5mm-10mm, for example, 5mm, 6mm, 8mm, 10mm, etc. In this way, it can ensure that the first dust receiving plate 2201 and the second dust receiving plate 2202 have a certain mechanical strength, and at the same time, it is avoided that the thickness of the first dust receiving plate 2201 and the second dust receiving plate 2202 is too thick to occupy more structural space at the entrance 101.

[0095] It should be noted that the material and thickness of the first dust receiving plate 2201 and the second dust receiving plate 2202 can be set to be the same or different, and the embodiment of the present application is not limited to this.

[0096] In some embodiments, there can be two adjusting members 2203, and the second direction Y of the two adjusting members 2203 are respectively arranged on both sides of the first dust receiving plate 2201 and the second dust receiving plate 2202, so as to use the two adjusting members 2203 to fix the first dust receiving plate 2201 and the second dust receiving plate 2202 from both sides to improve the connection firmness of the first dust receiving plate 2201 and the second dust receiving plate 2202.

[0097] It should be noted that the first dust collecting plate 2201 and the second dust collecting plate 2202 can also be set to a fixed connection, or an integrated structure, to facilitate actual installation operations. Technical personnel in this field can flexibly set it according to actual needs, and the embodiments of the present application are not limited to this.

[0098] Alternatively, if Figures 8 to 10 As shown, the adjusting member 2203 includes: a first connecting member 22031 and a second connecting member 22032; the first connecting member 22031 is fixedly connected to the first dust receiving plate 2201, and the second connecting member 22032 is fixedly connected to the second dust receiving plate 2202; one of the first connecting member 22031 and the second connecting member 22032 is provided with a plurality of connecting columns 22031a arranged at intervals, and the other of the first connecting member 22031 and the second connecting member 22032 is provided with a plurality of connecting holes 22032a arranged at intervals, and at least some of the connecting columns 22031a are inserted into the connecting holes 22032a.

[0099] In the embodiment of the present application, the first connecting member 22031 is connected to the first dust receiving plate 2201, and the second connecting member 22032 is connected to the second dust receiving plate 2202. The first connecting member 22031 and the second connecting member 22032 are plugged in and matched with each other through the connecting column 22031a and the connecting hole 22032a.

[0100] Furthermore, if Figure 4 and Figure 5 As shown, Figure 4 A schematic diagram of a dust collecting mechanism according to an embodiment of the present application is shown; Figure 5A schematic diagram shows the dust collecting mechanism of an embodiment of the present application in an extended state. By adjusting the plug-in position of the connecting column 22031a and the connecting hole 22032a, the effective dust collecting area of ​​the first dust collecting plate 2201 and the second dust collecting plate 2202 can be adjusted to better meet the demand for collecting impurities and prevent impurities from falling directly onto the workpiece 300 and causing contamination of the workpiece 300.

[0101] Among them, the connection method between the first connecting member 22031 and the first dust collecting plate 2201, as well as the connection method between the second connecting member 22032 and the second dust collecting plate 2202, can be fixed connections such as snap connection, bolt connection, welding, and bonding. Of course, other fixed connection methods can also be selected, and the embodiments of the present application are not limited to this.

[0102] In some embodiments, Figure 6 and Figure 7 As shown, the first dust receiving plate 2201 and the second dust receiving plate 2202 are respectively provided with first holes 22012 on both sides along the third direction Z; Figure 8 As shown, the first connecting member 22031 and the second connecting member 22032 are both provided with a second hole 22031b, the first connecting member 22031 is installed and matched with the first hole 22012 of the first dust receiving plate 2201 through the second hole 22031b, and the second connecting member 22032 is installed and matched with the first hole 22012 of the second dust receiving plate 2202 through the second hole 22031b.

[0103] Specifically, the first hole 22012 and the second hole 22031b can be set as threaded holes. During assembly, bolts can be used to thread the second hole 22031b of the first connecting member 22031 and the first hole 22012 of the first dust receiving plate 2201, respectively, so as to install and fix the first connecting member 22031 and the first dust receiving plate 2201.

[0104] Correspondingly, another bolt can be used to threadably connect the second hole 22031b of the second connecting member 22032 and the first hole 22012 of the second dust receiving plate 2202 respectively, so as to install and fix the second connecting member 22032 and the second dust receiving plate 2202.

[0105] In addition, if Figure 7 As shown, in the second dust receiving plate 2202, the dimension from the first hole 22012 to the end of the second dust receiving plate 2202 close to the first dust receiving plate 2201 is larger than the dimension of the end of the second dust receiving plate 2202 away from the first dust receiving plate 2201, that is, even if the overall center of gravity of the second dust receiving plate 2202 is located on the left side of the first hole 22012, when the first hole 22012 is connected to the second connecting member 22032, the problem of warping on the right side of the second dust receiving plate 2202 can be reduced.

[0106] Alternatively, if Figure 8 As shown, a plurality of connection pillars 22031a and a plurality of connection holes 22032a are arranged at intervals along the first direction X, and the distance between two adjacent connection pillars 22031a is equal to the distance between two adjacent connection holes 22032a.

[0107] In the embodiment of the present application, the structure of the connecting column 22031a in the first connecting member 22031 is adapted to the structure of the connecting hole 22032a in the second connecting member 22032, and the spacing between two adjacent connecting columns 22031a is set equal to the spacing between two adjacent connecting holes 22032a, so that according to the position adjustment requirements, any number and any position of connecting columns 22031a and connecting holes 22032a can be selected for plug-in combination to achieve the adjustment of the relative position of the first dust receiving plate 2201 and the second dust receiving plate 2202.

[0108] Alternatively, if Figures 4 to 7 As shown, a first step portion 22011 is provided at one end of the first dust receiving plate 2201 facing the second dust receiving plate 2202, and a second step portion 22021 is provided at one end of the second dust receiving plate 2202 facing the first dust receiving plate 2201, and the first step portion 22011 and the second step portion 22021 overlap each other.

[0109] In the embodiment of the present application, the first step portion 22011 on the first dust receiving plate 2201 and the second step portion 22021 on the second dust receiving plate 2202 overlap each other to achieve the overlapped cooperation between the first dust receiving plate 2201 and the second dust receiving plate 2202, thereby improving the connection stability between the first dust receiving plate 2201 and the second dust receiving plate 2202. At the same time, the step structure between the first dust receiving plate 2201 and the second dust receiving plate 2202 can reduce the thickness of the overlapped portion, thereby avoiding the overlapped portion being too thick and occupying more space at the entrance 101.

[0110] In some embodiments, the assembly and use process of the annealing equipment in the present application is as follows:

[0111] The first dust receiving plate 2201 and the second dust receiving plate 2202 are overlapped, and the first connecting member 22031 is installed on both sides of the first dust receiving plate 2201, and the second connecting member 22032 is installed on both sides of the second dust receiving plate 2202. The relative position of the first dust receiving plate 2201 and the second dust receiving plate 2202 is adjusted, and the first connecting member 22031 and the second connecting member 22032 are plugged and fixed to assemble the dust receiving assembly 220. Then, the first dust receiving plate 2201 is installed and fixed with the fixing member 210 to complete the assembly of the dust receiving mechanism 200.

[0112] Then, the dust collecting mechanism 200 is placed as a whole on the support frame 110 of the equipment body 100, and the dust collecting mechanism 200 is pushed so that the first dust collecting plate 2201 and the second dust collecting plate 2202 at least partially extend into the inlet 101, and the position of the dust collecting component 220 in the inlet 101 is adjusted so that the dust collecting component 220 can be used to receive the crystalline impurities that fall off the top wall of the inlet 101.

[0113] In addition, when the dust collecting mechanism 200 needs to be replaced or cleaned and maintained, the dust collecting mechanism 200 is pulled out from the inlet 101 to replace or clean the dust collecting mechanism 200. The operation is simple and convenient, and can prevent crystallized impurities on the top wall of the inlet 101 of the equipment body 100 from falling onto the workpiece 300.
