As shown in fig. 1 to 25, the wave soldering apparatus 001 according to the embodiment of the present application includes a body 1, a transfer rail (including, for example, a first rail 21, a preheating section rail 22, and a soldering section rail 23), a flux spraying device 5, a preheating device 6, and a soldering device 7.

The body 1 is formed with a feed port 11, a receiving chamber (not shown) and a discharge port 12 which are sequentially communicated. The transmission rail is arranged in the accommodating cavity, and extends from the feed inlet 11 to the discharge outlet 12, so that the product to be welded is conveniently fed from the feed inlet 11 to the discharge outlet 12.

The soldering flux spraying device 5, the preheating device 6 and the welding device 7 are arranged in the accommodating cavity and are arranged corresponding to the conveying track, and the soldering flux spraying device 5, the preheating device 6 and the welding device 7 are respectively distributed along the feeding direction of the conveying track in sequence.

The basic principle of operation of the wave soldering apparatus 001 is as follows: after the product to be soldered (such as a printed board with components and parts in advance) is placed on the conveying rail from the feed port 11, the conveying rail conveys the product to be soldered to pass through the soldering flux spraying device 5, the preheating device 6 and the soldering device 7 in sequence, and finally the soldered product flows out from the discharge port 12.

In the transportation process of the transmission track, the product to be welded firstly passes through the soldering flux spraying device 5, the soldering flux spraying device 5 is used for spraying soldering flux on the product so that the soldering flux completely infiltrates a plurality of welding spots on the product, then, the product passes through the preheating device 6 after being sprayed with the soldering flux, the preheating device 6 is used for heating the product so as to gradually raise the temperature of the product to be welded and activate the soldering flux, thereby enabling the soldering flux near the welding spots to reach the activation temperature required by welding, finally, the preheated product passes through the welding device 7 to be welded, and in the welding process, the printed board inserted with components is placed on the transmission track and passes through solder waves through a specific angle and a specific immersion depth to realize the welding of the welding spots, so that the welded product is finally obtained.

As shown in fig. 1 and 2, in some embodiments, the machine body 1 may be a machine body 1 disposed horizontally, where the inlet 11 is located at one end of the machine body 1 along its length, and the outlet 12 is located at the other end of the machine body 1 along its length. Of course, the specific shape of the body 1 is not particularly limited in this application.

In some embodiments, the transmission track may be a single track structure, or may be a multi-track structure such as a double track, a triple track, or even a four track. For example, the transfer track comprises two monorails arranged side by side (e.g., each comprising a first monorail 211, a preheating section monorail 221 and a welding section monorail 231), each comprising a rail and a chain claw assembled on the monorail, the rail spans between the feed inlet 11 and the discharge outlet 12, the chain claw is moved cyclically between the two ends of the rail, wherein the product to be welded is clamped between the two monorails and is fixed by the chain claw, and the product to be welded sequentially undergoes the processes of spraying flux, preheating, welding, etc. as the chain claw moves.

It should be noted that, the specific structure of the transmission rail is not limited in detail, so long as the transmission rail can transport the product to be welded. For convenience of description, the following explanation will be given by taking a transmission track as an example of a double track structure.

As shown in fig. 3 to 6, in order to solve the above-described problems in the related art, according to one embodiment of the present application, the transfer rail includes a first rail 21 and a second rail (not shown in the drawings) independent from each other, the first rail 21 corresponding to the flux spraying device 5, and the second rail corresponding to the preheating device 6 and the soldering device 7.

In this embodiment, the transmission track is divided into at least two sections of tracks which are independently arranged, wherein the first track 21 corresponds to the soldering flux spraying device 5, and the second track corresponds to the preheating device 6 and the welding device 7, and it can be understood that, since the first track 21 and the second track are independently arranged, soldering flux only remains on the first track 21, and soldering flux residues do not appear on the second track, so that pollution caused by the existence of soldering flux residues on the tracks in the welding process can be avoided.

In summary, according to the wave soldering apparatus 001 of the present embodiment, since the first rail 21 and the second rail are disposed independently of each other, flux residue on the first rail 21 is not transferred to the second rail, so that the second rail is prevented from generating attached contaminants after the welding is completed, cleaning and maintenance of the whole transmission rail are facilitated, and the welding yield in the welding process is ensured since no contaminants such as tin dross are generated on the second rail. In addition, on the first track 21 and the second track that mutually independent set up, the load of transmission structure such as chain is lighter to the structural stability of first track 21 and second track is stronger, and transmission track installation and dismantlement are also simple and convenient more.

As shown in fig. 5, in some embodiments, the first track 21 is horizontally disposed, so that the flux sprayed onto the product to be welded can be prevented from flowing to other positions due to the action of gravity, so that the flux can accurately cover the welding spot, and the subsequent welding process is facilitated.

As shown in fig. 5 and 6, in one embodiment of the present application, the feeding end of the first rail 21 is disposed opposite to the feeding inlet 11, the discharging end of the first rail 21 is disposed opposite to the feeding end of the second rail, and the discharging end of the first rail 21 is disposed adjacent to the feeding end of the second rail to facilitate the transfer of the product to be welded from the first rail 21 to the second rail.

It should be noted that, the transfer of the product to be welded may be achieved by some transition device between the first rail 21 and the second rail, and the discharge end of the first rail 21 and the discharge end of the second rail may not adopt a structure that is opposite and adjacently arranged. For example, the transition device may be a mechanical arm structure, where the mechanical arm achieves the transfer of the product to be welded between the first track 21 and the second track through a preset programming.

As shown in fig. 6, in one embodiment of the present application, the width of the first rail 21 and the width of the second rail are the same, and the conveying speed of the first rail 21 is the same as that of the second rail, so that smooth and stable transfer of the product to be welded between the first rail 21 and the second rail can be ensured.

According to some embodiments of the present application, the second track may be a one-section track structure or a segmented track structure, which is not particularly limited herein.

As shown in fig. 5 and 6, in one embodiment of the present application, the second rail includes a preheating section rail 22 and a welding section rail 23 that are independent from each other, the preheating section rail 22 corresponding to the preheating device 6, and the welding section rail 23 corresponding to the welding device 7.

Like this, through designing the transmission track into three mutually independent first tracks 21, preheating section track 22 and welding section track 23, can further alleviate the load of transmission structures such as chain on the single section track, improve overall structure's stability to three section track structure's installation and dismantlement are also simple and convenient more.

As shown in fig. 6, in one embodiment of the present application, the discharge end of the preheating section rail 22 is disposed opposite the feed end of the welding section rail 23, and the discharge end of the preheating section rail 22 is disposed adjacent the feed end of the welding section rail 23 to facilitate the transfer of the product to be welded from the preheating section rail 22 to the welding section rail 23. It should be noted that, a transition device (e.g., a mechanical arm structure) may be used between the preheating section rail 22 and the welding section rail 23 to transfer the product to be welded, and a structure disposed opposite and adjacent to the discharge end of the preheating section rail 22 and the discharge end of the welding section rail 23 may not be used.

As shown in fig. 6, in one embodiment of the present application, the width of the preheating section rail 22 and the width of the welding section rail 23 are the same, and the transfer speed of the preheating section rail 22 and the transfer speed of the welding section rail 23 are the same, so that smooth and stable transfer of the product to be welded between the preheating section rail 22 and the welding section rail 23 can be ensured.

According to one embodiment of the present application, the first track 21, the preheating section track 22 and the welding section track 23 are driven by different driving assemblies (not shown in the figures), respectively.

In this embodiment, the first track 21, the preheating section track 22 and the welding section track 23 can be controlled independently by different driving components, on one hand, the transportation process of one or two of the three sections of tracks is convenient to adjust, so that more usage scenarios can be adapted, and on the other hand, compared with the control structure in the related art that one section of track is driven by one group of driving components, the three sections of tracks are driven by three groups of different driving components respectively, so that the load pressure of a single group of driving components is reduced, the service life is prolonged, and the energy consumption of the whole wave soldering device 001 is reduced.

In one embodiment of the present application, the first track 21 corresponds to a first drive assembly (not shown), the preheating section track 22 corresponds to a second drive assembly (not shown), and the welding section track 23 corresponds to a third drive assembly (not shown). The controller of the wave soldering apparatus 001 can control the start and stop of the three-section track (i.e., the first track 21, the preheating section track 22, and the soldering section track 23) and the transfer speed according to the position of the product to be soldered. For example, when the product to be welded is about to enter the first rail 21, the controller controls the first driving assembly to drive the first rail 21 to start running; when the product to be welded is about to enter the preheating section track 22, the controller controls the second driving component to drive the preheating section track 22 to start running, and then when the product to be welded enters the preheating section track 22, the controller can control the first driving component to be closed, so that the power is further saved, and the energy consumption is reduced.

Of course, the control method of the controller for controlling the first driving assembly, the second driving assembly and the third driving assembly is not particularly limited, and the user can adjust the control method of the driving assemblies according to specific use situations and use requirements.

Taking a transmission track as a double-track structure as an example for explanation: the transmission track comprises two monorails which are arranged side by side, the distance between the two monorails is adjustable, namely the width of the transmission track is adjustable, so that the transmission track can adapt to products to be welded with different sizes, and the width of the transmission track can be adjusted through the width adjusting device 3. The width direction of the transfer rail means a direction from one rail to the other rail of the transfer rail. Specifically, as shown in fig. 5 and 6, when the transfer rail is of a multi-stage structure, the first rail 21 includes two first monorails 211 disposed side by side, the preheating stage rail 22 includes two preheating stage monorails 221 disposed side by side, and the welding stage rail 23 includes two welding stage monorails 231 disposed side by side.

When the transmission track is of a multi-section structure, that is, the transmission track comprises a first track 21 and a second track, or the transmission track comprises a first track 21, a preheating section track 22 and a welding section track 23, a width adjusting device 3 can be arranged on the transmission track, for example, the first track 21, the preheating section track 22 and the welding section track 23 are in transmission connection with the same width adjusting device 3, so that the width of the whole transmission track can be adjusted by the width adjusting device 3, and the width of the whole transmission track can be conveniently managed; or, at least two width adjusting devices 3 may be disposed on the transmission track, as shown in fig. 5 and 6, the first track 21, the preheating section track 22 and the welding section track 23 respectively perform width adjustment through different width adjusting devices 3, so that independent adjustment of widths of different tracks can be realized, and the width adjusting mode is more flexible.

As shown in fig. 7, in one embodiment of the present application, the width adjustment device 3 includes a width adjustment driving member 31, a width adjustment screw rod 32, and a width adjustment nut 33, the width adjustment driving member 31 is in transmission connection with the width adjustment screw rod 32, the width adjustment screw rod 32 extends along the width direction of the transmission track, and the width adjustment nut 33 is adapted to move along the width direction of the transmission track with the rotation of the width adjustment screw rod 32; the width adjusting nut 33 is fixedly connected with one single rail (such as a preheating section single rail 221 in fig. 7) of the transmission rail.

In this embodiment, the width adjusting driving member 31 drives the width adjusting screw rod 32 to rotate, and the width adjusting screw rod 32 rotates to drive the width adjusting nut 33 to move along the width adjusting screw rod 32, so as to drive the monorail fixed on the width adjusting nut 33 to move along the width direction of the transmission track, thereby realizing the adjustment of the distance between two monorails of the transmission track, that is, realizing the width adjustment of the transmission track.

It should be noted that the foregoing embodiment belongs to one of many embodiments of the present application, and is not limited to this application, and the width adjustment device 3 may also take other structures to implement width adjustment of the transmission track, for example, the width adjustment device 3 includes a linear driving member, where the linear driving member drives a single rail of the transmission track to move along a width direction thereof to implement width adjustment. Furthermore, the width adjustment device 3 may also control both monorails of the conveyor track to be moved simultaneously for width adjustment, e.g. the width adjustment device 3 comprises two linear drives, one of which drives the monorail on one side of the conveyor track and the other of which drives the monorail on the other side of the conveyor track. The specific structure and width adjusting mode of the width adjusting device 3 are not particularly limited, so long as the width adjusting device 3 can realize width adjustment of the transmission track.

As shown in fig. 4, in one embodiment, the mounting frame includes a preheat mounting frame 65, the preheat mounting frame 65 for supporting and securing the preheat device 6.

As shown in fig. 7, in some embodiments of the present application, the width adjusting device 3 further includes a width adjusting fixing seat 34 and a width adjusting movable seat 35, the width adjusting fixing seat 34 is fixed on the mounting frame, two ends of the width adjusting fixing seat 34 respectively correspond to two sides of the width direction of the transmission track, two ends of the width adjusting screw rod 32 are respectively rotatably installed at two ends of the width adjusting fixing seat 34, and the width adjusting nut 33 is fixedly connected with a single rail of the transmission track through the width adjusting movable seat 35.

As shown in fig. 7, in some embodiments, when the transmission track includes a first track 21, a preheating section track 22 and a welding section track 23 that are independently disposed, two sets of width adjustment devices 3 are disposed at two ends of the preheating section track 22, the two sets of width adjustment devices 3 are synchronously driven by a synchronous driving rod 37, the specific structure of the width adjustment devices 3 is described in detail above, and the width adjustment devices 3 are also disposed on the first track 21 and the welding section track 23, and the structure of the width adjustment devices is similar to that of the width adjustment devices 3 on the first track 21, which is not described herein.

It should also be added that, in addition to the width of the transmission rail being adjustable by the width adjustment device 3, the transmission rail can also be adjusted by the angle adjustment device 4 by adjusting the inclination angle of the transmission rail with respect to the horizontal plane, the specific structure being shown in fig. 6.

When the transmission track is of a multi-section structure, an angle adjusting device 4 can be arranged on the transmission track, for example, the first track 21, the preheating section track 22 and the welding section track 23 are in transmission connection with the same angle adjusting device 4, so that the width of the whole transmission track can be adjusted by the angle adjusting device 4, and the inclination angle of the whole transmission track can be conveniently managed; or, the transmission track may also be provided with at least two angle adjusting devices 4, for example, the first track 21, the preheating section track 22 and the welding section track 23 respectively perform angle adjustment through different angle adjusting devices 4, so that independent adjustment of angles of different sections of the transmission track can be realized, and the angle adjusting mode is more flexible.

In some embodiments of the present application, the angle adjusting device 4 may perform angle adjustment by driving one end of the transmission rail in the feeding direction to lift, for example, the angle adjusting device 4 may adopt a transmission structure such as a screw nut structure, a chain transmission structure, a link structure, and a linear driving member or a rotary driving member corresponding to the transmission structure, so as to lift one end of the transmission rail, and further implement angle adjustment of the transmission rail. Of course, the adjusting structure and the adjusting manner of the angle adjusting device 4 are not particularly limited in this application, as long as the angle adjusting device 4 can adjust the inclination angle of the transmission track.

The flux nozzle may be disposed above or below the first track 21, and the movement of the flux nozzle may be achieved through a screw nut, a connecting rod, a chain, or the like, which is not particularly limited herein.

In the related art, wave soldering equipment generally adopts an integral preheating module and a variable frequency fan to preheat a product to be soldered, and the preheating structure and the preheating mode have the following defects: because the preheating module belongs to a whole, the preheating module can only be opened or closed integrally, and the adaptation adjustment can not be realized according to the specific size of the product, for example, if the whole preheating module is opened when the width size of the printed board is smaller, only a small part of heat can be transferred to the printed board, and most of heat can be wasted, so that the preheating module has higher energy consumption and lower energy utilization rate.

As shown in fig. 8 to 16, in order to solve the above technical problems, according to one embodiment of the present application, the preheating device 6 includes a plurality of preheaters 601, and at least two preheaters 601 are provided in the machine body 1 in the width direction along the transfer rail.

The transfer track is illustrated as including a preheat section track 22: at least two preheaters 601 are provided in the width direction of the preheating section rail 22.

The preheating device 6 is adapted to operate according to target operating parameters, including the number of on-times, the on-time or the on-power of the preheaters 601, depending on its position change with the preheating section track 22.

In this embodiment, as shown in fig. 8, the preheating device 6 includes a plurality of independently arranged preheaters 601, and the plurality of preheaters 601 are distributed along the width direction of the preheating section track 22, when the size of the product to be welded is smaller, the width of the corresponding preheating section track 22 is also smaller, at this time, the preheaters 601 of the preheating device 6 can be opened by a specific number according to the width of the preheating section track 22, so that the number of the opened preheaters 601 is matched with the specific size of the product to be welded, and thus, the wave soldering apparatus 001 of the present application can control the number of the opened preheaters 601 according to specific requirements, thereby reducing the energy consumption of the preheating device 6, reducing the waste of heat, and greatly improving the energy utilization rate.

In addition, the wave soldering device 001 of the present application can also control the opening time of the preheater 601 according to the position of the product to be soldered on the preheating section track 22 relative to the preheating device 6 and the transportation speed thereof; alternatively, the turn-on power of the preheater 601 may also be controlled according to the height relationship between the preheating section track 22 and the preheating device 6. Of course, the above-described embodiments are only some of the numerous embodiments of the present application, and do not constitute a specific limitation of the present application.

It should be further noted that, in the above embodiment, the conveying track may be a one-stage structure or a segmented structure, and when the conveying track is a one-stage structure, the preheating-stage track 22 refers to a portion of the conveying track corresponding to the preheating device 6; when the transfer rail is of a sectional structure, the preheating section rail 22 refers to a preheating section rail 22 provided independently of the first rail 21 and the welding section rail 23.

As shown in fig. 8, according to one embodiment of the present application, the preheating device 6 includes an upper preheater group 61 located above the preheating stage rail 22 and a lower preheater group 62 located below the preheating stage rail 22, with a preheating space 602 formed between the upper preheater group 61 and the lower preheater group 62.

As shown in fig. 9 to 12, the upper layer preheater group 61 includes at least two preheaters 601 arranged in the width direction of the preheating section track 22, the lower layer preheater group 62 includes at least two preheaters 601 arranged in the width direction of the preheating section track 22, and the preheaters 601 in the upper layer preheater group 61 and the preheaters 601 in the lower layer preheater group 62 are respectively in one-to-one correspondence.

In this embodiment, the preheating section track 22 passes through the preheating space 602, so that the product to be welded transported on the preheating section track 22 can be heated by the upper layer preheater set 61 and the lower layer preheater set 62 at the same time, so that the product to be welded is heated more uniformly and sufficiently, and the activation effect of the soldering flux on the product to be welded is better.

In one embodiment of the present application, the number of preheaters 601 in the upper layer preheater group 61 may be two, three or four, etc., and correspondingly, the number of preheaters 601 in the lower layer preheater group 62 may be two, three or four, etc., which are not particularly limited herein.

As shown in fig. 9 and 10, the description is given taking, as an example, that the upper layer preheater group 61 and the lower layer preheater group 62 each include two preheaters 601: the width of the preheating section track 22 can be adjusted according to the size of the product to be welded, and if the size of the product to be welded is smaller, the width adjusting device 3 adjusts the width of the preheating section track 22 to be the width matched with the size of the product to be welded.

During the process of transporting the products to be welded by the preheating section track 22, the upper layer preheater group 61 and the lower layer preheater group 62 will adjust the opening number of the internal preheaters 601 according to the width relationship between the preheating section track 22 and the preheaters 601. For example, if the preheating section track 22 is wider than the width of a single preheater 601, both preheaters 601 of the upper preheater group 61 and both preheaters 601 of the lower preheater group 62 are all on; if the width of the preheating section track 22 is smaller than or equal to the width of the single preheater 601, only one preheater 601 is started in each of the upper layer preheater group 61 and the lower layer preheater group 62, and the positions of the started preheaters 601 correspond to those between the preheating section track 22, so that the energy consumption of the whole preheating device 6 is saved, and the energy utilization rate is improved.

It should be noted that, the "position corresponding" and "corresponding setting" described in the context of the present application may be simply understood as the relative setting between the two components, but the explanation of the "position corresponding" and "corresponding setting" described above is not limited thereto, for example, if the preheater 601 adopts a hot air heating structure, the "position corresponding between the opened preheater 601 and the preheating stage track 22" may refer to: a hot air flow path exists between the preheating section rail 22 and the preheater 601 in the on state.

According to some embodiments of the present application, the preheater 601 may adopt a heating structure such as hot air heating, electric plate convection, electric bar heating, infrared heating, etc., which is not particularly limited herein.

As shown in fig. 15 and 16, the following description will take a hot air heating structure as an example of the preheater 601: the preheater 601 includes a fan drive 6011, a fan 6012, and a heater 6013.

In the direction toward the preheating section rail 22, a fan driving member 6011, a fan 6012, and a heating member 6013 are sequentially stacked, the fan driving member 6011 being adapted to drive the fan 6012 to blow air toward the heating member 6013, the fan 6012 being adapted to blow heat air generated by heating via the heating member 6013 to the preheating section rail 22.

In a specific heating process of the preheater 601, the fan driving member 6011 drives the fan 6012 to blow air to the heating member 6013, and the air flow is heated by the heating member 6013 to form a hot air flow, and the hot air flow flows to the preheating section track 22, so that the product to be welded is preheated.

As shown in fig. 8, in some embodiments, the preheater 601 of the upper preheater group 61 blows hot air downward, and the preheater 601 of the lower preheater group 62 blows hot air upward, and the two hot air streams meet and generate convection in the preheating space 602, thereby heating the printed board in the preheating space 602.

As shown in fig. 16, according to an embodiment of the present application, a mounting cover 6014 is further provided between the preheating section rail 22 and the fan 6012, and the heating member 6013 is covered inside the mounting cover 6014. The mounting cover 6014 is formed with a flow passage along the air supply direction of the fan 6012 to communicate with the fan 6012 and the preheating space 602, respectively.

Thus, the mounting cover 6014 can not only avoid the potential safety hazard caused by the contact between the heating element 6013 and other components, but also realize the smooth circulation of air flow between the fan 6012 and the preheating space 602 through the air supply channel, thereby ensuring the safety performance and the preheating effect at the same time.

As shown in fig. 16, in some embodiments, a plurality of ventilation holes 6015 are formed in each of the upper and lower surfaces of the mounting cover 6014, and the ventilation holes 6015 form the air supply passage. Specifically, the plurality of circulation holes 6015 may be uniformly distributed along the upper and lower surfaces of the installation cover 6014, thereby achieving uniform air supply to the preheating space 602.

As shown in fig. 7 and 11, according to one embodiment of the present application, a heat insulating member 64 that is retractable along the width direction of the preheating section track 22 is further provided in the accommodating chamber to extend into or out of the preheating space 602, and the heat insulating member 64 is adapted to fill a portion of the preheating space 602 corresponding to the preheater 601 in the closed state.

Thus, when the preheater 601 of the preheating device 6 is fully opened, the heat insulating member 64 is located outside the preheating space 602, so that adverse effects of the heat insulating member 64 on the preheating process can be avoided; as shown in fig. 12, when the preheater 601 of the preheating device 6 is partially opened, the heat insulating member 64 is extended into the preheating space 602, at this time, the heat insulating member 64 fills a part of the preheating space 602, and the part of the preheating space 602 which is filled corresponds to the preheater 601 in the off state, and the part of the preheating space 602 which is not filled corresponds to the preheater 601 in the on state.

In summary, on the one hand, if the preheater 601 of the preheating device 6 is partially turned on, the heat insulation member 64 fills the empty cavity in the preheating space 602, so that heat loss can be reduced, and heat is ensured to be concentrated near the product to be welded, so that the energy consumption of the preheating device 6 is further reduced, and the energy utilization rate and the heating effect are optimized; on the other hand, if the preheater 601 is fully turned on, the heat insulator 64 may also be retracted to the outside of the preheating space 602, thereby avoiding adverse effects on the preheating process.

In this embodiment, during the width adjustment process, the width adjustment device 3 drives one preheating section single rail 221 of the preheating section rail 22 to move along the width direction of the preheating section rail 22, and the heat insulating member 64 stretches along with the movement of the preheating section single rail 221, so as to extend into or out of the preheating space 602. Specifically, as shown in fig. 11 and 12, if the width of the preheating section track 22 is reduced, the heat insulator 64 will extend into the preheating space 602 and fill part of the preheating space 602; as shown in fig. 11 and 12, if the width of the preheating stage rail 22 is increased, the heat insulating member 64 is shortened, and, in the course of the gradual increase of the width of the preheating stage rail 22, when the width of the preheating stage rail 22 is the same as the width of the preheating space 602, the heat insulating member 64 is shortened to the outside of the preheating space 602.

Thus, the heat insulation piece 64 can automatically move to a required position in the track width adjusting process, so that the position of the heat insulation piece 64 can be automatically adjusted, and the accurate heat insulation of the heat insulation piece 64 can be realized.

As shown in fig. 11 and 12, according to one embodiment of the present application, the height of the heat insulating member 64 is adapted to the height of the preheating space 602, thereby securing the heat insulating effect of the heat insulating member 64. Further, since the concertina-like structure is more stretchable, the heat insulator 64 can be designed as an accordion-like elastic heat insulating plate. Of course, the specific structure and size of the heat insulating member 64 are not limited thereto, as long as the heat insulating member 64 can fill part of the preheating space 602 and perform a heat insulating function.
