As shown in fig. 1 to 25, a wave soldering apparatus 001 according to an 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 machine body 1 is formed with a feed inlet 11, a containing cavity (not shown in the figure) and a discharge outlet 12 which are communicated in sequence. The conveying track is arranged in the containing cavity and extends from the feeding hole 11 to the discharging hole 12, so that a product to be welded is fed from the feeding hole 11 to the discharging hole 12 conveniently.

Scaling powder atomizer 5, preheating device 6 and welding set 7 all locate and hold the intracavity and all correspond the setting with the transmission track to scaling powder atomizer 5, preheating device 6 and welding set 7 distribute in proper order along transmission track's pay-off direction respectively.

The basic working principle of the wave soldering device 001 is as follows: after products to be welded (such as printed boards with components and parts in advance) are placed on the conveying track from the feeding port 11, the products to be welded are conveyed by the conveying track to sequentially pass through the scaling powder spraying device 5, the preheating device 6 and the welding device 7, and finally the products after welding flow out from the discharging port 12.

In the transportation process of the transmission track, a 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 can completely infiltrate a plurality of welding points 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 that the temperature of the product to be welded is gradually increased, the soldering flux is activated, the soldering flux near the welding points reaches the activation temperature required by welding, finally, the product after being preheated is welded through the welding device 7, in the welding process, a printed board with components inserted is arranged on the transmission track, and penetrates through solder waves through a specific angle and a specific immersion depth to realize the welding of the welding points, 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 horizontal machine body 1, the feeding port 11 is located at one end of the machine body 1 along the length direction thereof, and the discharging port 12 is located at the other end of the machine body 1 along the length direction thereof. Of course, the specific shape of the body 1 is not limited in detail in the present application.

In some embodiments, the conveying track may be a single track structure, or may be a multi-track structure such as a double track, a three-track, or even a four-track structure. For example, the conveying track includes two single tracks arranged side by side (for example, each single track includes a first single track 211, a preheating section single track 221 and a welding section single track 231), each single track includes a guide rail and a chain claw assembled on the single track, the guide rail spans between the feeding port 11 and the discharging port 12, the chain claw moves circularly between two ends of the guide rail, wherein the product to be welded is clamped between the two single tracks and is fixed by the chain claw, and the product to be welded sequentially passes through the processes of flux spraying, preheating, welding and the like along with the movement of the chain claw.

It should be noted that, the specific structure of the conveying track is not limited in detail in the present application, as long as the conveying track can transport the product to be welded. For convenience of description, the following explanation takes the conveying track as a dual-track structure as an example.

In the related art, the conventional wave soldering apparatus generally transports products using a one-stage track and a chain claw structure, however, the above-mentioned one-stage track in the related art has the following disadvantages: the one-section track is difficult to clean and maintain, and the chain claw of one-section track can be through spouting the scaling powder, preheating, welding and cooling whole stage, and wherein, the scaling powder residue can be adhered to behind the scaling powder atomizer to the chain claw, when the chain claw that adheres to scaling powder residue marchs to the welding position, the scaling powder residue on the chain claw can contact the wave crest and cause the molten tin bath pollution to the tin dross can adhere on the chain claw, and the residue on the chain claw is very difficult to clean, will cause very big harmful effects to the welding yield. In addition, the installation and the disassembly of the one-section track are more complicated and cumbersome, and the load of the chain is also larger.

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

In the embodiment, the conveying 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, the second track corresponds to the preheating device 6 and the welding device 7, and it can be understood that, because the first track 21 and the second track are independently arranged, the soldering flux only remains on the first track 21, and the soldering flux residue does not appear on the second track, so that the pollution caused by the soldering flux residue existing on the tracks in the welding process can be avoided.

In conclusion, according to the wave soldering device 001 of the embodiment, because the first rail 21 and the second rail are arranged independently, the flux residues on the first rail 21 cannot be transferred to the second rail, so that the second rail can be prevented from generating attached pollutants after the soldering is completed, the whole transmission rail can be cleaned and maintained conveniently, and the soldering yield in the soldering process is ensured because the pollutants such as tin dross and the like no longer appear on the second rail. In addition, on the first track 21 and the second track that set up independently each other, 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 rail installation and dismantlement are also simple and convenient more.

As shown in fig. 5, in some embodiments, the first rail 21 is horizontally disposed, so that the flux sprayed on the product to be welded can be prevented from flowing to other positions due to gravity, and the flux can accurately cover the welding point, thereby facilitating the subsequent welding process.

As shown in fig. 5 and 6, in one embodiment of the present application, the feed end of the first rail 21 is disposed opposite the feed port 11, the discharge end of the first rail 21 is disposed opposite the feed end of the second rail, and the discharge end of the first rail 21 is disposed adjacent the feed end of the second rail to facilitate the products to be welded being handed over from the first rail 21 to the second rail.

It should be noted that the first rail 21 and the second rail may also be provided with some transition device to realize the transfer of the products to be welded, and the discharge end of the first rail 21 and the discharge end of the second rail may not be provided with an opposite and adjacent structure. For example, the transition means may be in the form of a robot arm which, through preset programming, effects the transfer of the products to be welded between the first track 21 and the second track.

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 to-be-welded product 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-segment track structure or a segmented track structure, and the present application is not limited thereto.

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

Like this, through designing transmission track for three sections mutually independent first track 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 the installation and the dismantlement of syllogic track structure are also simple and convenient more.

As shown in fig. 6, in one embodiment of the present application, the discharge end of the pre-heat section track 22 is disposed opposite the feed end of the welding section track 23, and the discharge end of the pre-heat section track 22 is disposed adjacent the feed end of the welding section track 23 to facilitate the product to be welded being handed over from the pre-heat section track 22 to the welding section track 23. It should be noted that the preheating section track 22 and the welding section track 23 may also be connected by some transition device (e.g., a mechanical arm structure) to realize the transfer of the products to be welded, and the opposite and adjacent structure between the discharging end of the preheating section track 22 and the discharging end of the welding section track 23 may not be adopted.

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

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

In this embodiment, the first track 21, the preheating section track 22, and the welding section track 23 can be controlled independently through different driving assemblies, on one hand, adjustment is convenient for a transportation process of one or two of the three sections of tracks, so that more use scenes can be adapted, and on the other hand, compared with a control structure in which a group of driving assemblies is used to drive a single section of track in the related art, the embodiment adopts three groups of different driving assemblies to drive the three sections of tracks respectively, so that load pressure of a single group of driving assemblies is reduced, service life is prolonged, and energy consumption of the whole wave soldering device 001 is reduced.

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

Of course, the control method for controlling the first driving assembly, the second driving assembly and the third driving assembly by the controller is not particularly limited in this application, and the user may adjust the control method for the driving assemblies according to a specific use scenario and a use requirement.

The following description will be given by taking a conveying track as a double-track structure: the conveying track comprises two single tracks arranged side by side, the distance between the two single tracks is adjustable, namely the width of the conveying track is adjustable, so that the conveying track can adapt to products to be welded with different sizes, and the width of the conveying track can be adjusted through the width adjusting device 3. It should be noted that the width direction of the conveying track refers to a direction from one monorail of the conveying track to the other monorail. Specifically, as shown in fig. 5 and 6, when the conveying track is of a multi-section structure, the first track 21 includes two first monorail 211 arranged side by side, the preheating section track 22 includes two preheating section monorail 221 arranged side by side, and the welding section track 23 includes two welding section monorail 231 arranged side by side.

When the transmission track is in a multi-section structure, that is, the transmission track includes the first track 21 and the second track, or the transmission track includes the first track 21, the preheating section track 22 and the welding section track 23, the transmission track may be provided with a width adjusting device 3, for example, the first track 21, the preheating section track 22 and the welding section track 23 are all in transmission connection with the same width adjusting device 3, so that one width adjusting device 3 can realize width adjustment of the whole transmission track, and management of the width of the whole transmission track is facilitated; or, at least two width adjusting devices 3 may be disposed on the conveying 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 achieved, and the width adjusting manner is more flexible.

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

In the 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 conveying track, thereby realizing the adjustment of the distance between two monorail of the conveying track, that is, the width adjustment of the conveying track.

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, the air flow passes through the heating member 6013 to be heated to form a hot air flow, and the hot air flow flows to the preheating section rail 22, so as to preheat a product to be welded.

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

Specifically, as shown in fig. 11 and 12, if the width of the preheating section rail 22 is reduced, the heat insulating member 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 adjusted to be larger, the heat insulator 64 is shortened, and, in the process of gradually adjusting the width of the preheating stage rail 22 to be larger, when the width of the preheating stage rail 22 is the same as the width of the preheating space 602, the heat insulator 64 is shortened to the outside of the preheating space 602.
