Detailed Description

In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, a flux applying apparatus includes a reservoir 10, an applying member 20, and a first driving member 30, the reservoir 10 storing flux; as shown in fig. 4, the coating member 20 is partially disposed in the reservoir 10 for contacting the flux, and partially disposed outside the reservoir 10 for contacting the object to be coated; the first driving assembly 30 is connected to and drives the coating member 20 to move in the coating direction.

The above is the core technical content of the present invention, wherein, the coating member 20 is used for sucking the soldering flux in the storage tank 10 and coating the soldering flux on the object to be coated along the coating direction under the driving of the first driving assembly 30; the movement distance of the coating member 20 along the coating direction can be controlled by the first driving assembly 30, so that the coating member can be adapted to objects to be coated with different sizes, and the applicability is improved; the coating piece 20 directly coats the flux on the object to be coated, so that the flux can be prevented from splashing, and the coating effect can be ensured.

It should be noted that the "coating direction" in the present invention does not refer to a specific direction, which is specifically the extending direction of the position of the object to be coated, to which the flux is to be coated. That is, the "coating member 20 moves in the coating direction" is to be specific, the coating member 20 moves along the position to be coated under the driving of the first driving assembly 30, so as to coat the flux on the position of the substance to be coated where the flux is required to be coated.

In the invention, one end of the coating member 20 is in contact with the soldering flux, and the other end of the coating member 20 is in contact with the object to be coated, so that the soldering flux wets the coating member 20 and the coating member 20 can guide the soldering flux to the object to be coated. Specifically, the coating member 20 is made of a hydrophilic material or a material having a capillary effect, so as to facilitate the overall wetting of the coating member 20. Preferably, in this embodiment, the coating member 20 is a sponge, and is partially immersed in the flux to absorb the flux to wet the sponge, thereby facilitating the coating of the flux on the portion of the coating member disposed outside the storage tank 10 in contact with the object to be coated. The brush in the embodiment has better wear resistance and corrosion resistance and long service life. As a modification, a material that absorbs water, such as a brush, may be used for the coating member 20.

Further, as shown in fig. 4, two spaced coating members 20 may be provided in the coating direction. If only one applicator member 20 is provided, the applicator member 20 needs to be "walked" one complete pass along the location to be coated to spread the flux over the entire location to be coated when the flux is applied. After two coating pieces 20 are arranged at intervals, when the position to be coated is 'walked' once, the distance of the movement of one coating piece 20 arranged in front along the coating direction is compared with the original distance, so that the interval length of the two coating pieces 20 can be reduced, and the coating efficiency of the soldering flux is accelerated.

As a variant, it is also possible to arrange the applicator member 20 as a whole with a certain length in the application direction, which likewise makes it possible to reduce the movement distance of the application end arranged "in front" and thus to accelerate the application efficiency.

In one embodiment, the first driving assembly 30 is coupled to the coating member 20 to directly drive the coating member 20 in a coating direction. At this time, the reservoir 10 is relatively fixed in position, and the reservoir 10 is provided with a certain length in the coating direction, so that the coating member 20 is moved in the coating direction within the reservoir 10.

In another embodiment, the first driving assembly 30 is connected to the storage tank 10 to drive the storage tank 10 and thus the coating member 20 in the storage tank 10 to move along the coating direction. Preferably, as shown in fig. 1 and 2, the first driving assembly 30 includes a first driving member 31 and a guide member 32, the guide member 32 is disposed along the coating direction, the reservoir 10 is slidably coupled to the guide member 32, and the first driving member 31 is used to drive the reservoir 10 and the coating member 20 to move along the guide member 32. The guide member 32 can guide the traveling direction and the traveling path of the reservoir 10 and the coating member 20 to move in the coating direction, so that the coating member 20 can be controlled to coat the site to be coated with the coating object. In particular, the guide 32 is preferably a guide rail or rod; in order to reduce the equipment space footprint, the first drive member 31 is preferably a rodless cylinder.

Because the soldering flux is volatile and corrosive, in order to avoid large-area volatilization of the soldering flux into air, the upper end of the storage tank 10 is provided with the detachable cover plate 11, and the cover plate 11 can play a role in sealing and simultaneously avoid large-area overflow of the soldering flux; further, a first through hole 12 is provided on the cover plate 11, and the coating member 20 passes through the first through hole 12, whereby one end of the coating member 20 is positioned below the cover plate 11 for contacting the flux and the other end of the coating member 20 is positioned above the cover plate 11 for contacting the object to be coated. Meanwhile, by providing the detachable cover plate 11, it is convenient to replace the coating member 20.

In one embodiment, when the object to be coated needs to be coated with the flux, the object to be coated is carried to the position to be coated by a carrying device (not shown) to be close to the coating member 20, and the first driving assembly 30 drives the coating member 20 to move along the coating direction to complete the coating of the flux.

In another embodiment, as shown in fig. 1 or 3, the flux coating apparatus may further include a second driving assembly 70 to drive the coating member 20 to reciprocate toward the object to be coated. In order to avoid the coating member 20 from escaping the flux in the reservoir 10, the second driving assembly 70 is preferably connected to the reservoir 10 so as to drive the reservoir 10 and further the coating member 20 back and forth towards the object to be coated, i.e. to drive the reservoir 10 and further the coating member 20 towards or away from the object to be coated. In this embodiment, the second driving assembly 70 comprises a second driving member, the driving end of which is connected to the reservoir 10 to drive the reservoir 10 and the applicator 20 back towards the object to be coated. In other embodiments, the second driving assembly 70 may also include a second driving member and a second guiding member disposed toward the object to be coated, the second guiding member being used for guiding the storage tank 10 to move toward the object to be coated or away from the object to be coated, wherein the second driving member is preferably a pneumatic cylinder; the second guide is preferably provided with a guide rod or rail in the vertical direction. Specifically, a second drive assembly 70 is preferably provided to drive the reservoir 10 and the applicator member 20 in a vertical direction. That is, in the non-coated state, the object to be coated is above the coating member 20. When the object to be coated is in place, the second driving assembly 70 drives the storage tank 10 and the coating member 20 to move upwards until the coating member 20 abuts against the position to be coated, the first driving assembly 30 further drives the coating member 20 to move along the coating direction to fully coat the soldering flux on the position to be coated, and then the second driving assembly 70 drives the storage tank 10 and the coating member 20 to move downwards to be far away from the object to be coated, so that the object to be coated is convenient to transfer. By moving in the vertical direction, the flux can be prevented from overflowing from the reservoir tank 10.

More specifically, the storage tank 10 is arranged at the output end of the first driving assembly 30, the first driving assembly 30 is arranged at the output end of the second driving assembly 70, and the second driving assembly 70 drives the first driving assembly 30 to further drive the storage tank 10 and the coating member 20 to be close to or far away from the object to be coated; or, the storage tank 10 is disposed at the output end of the second driving assembly 70, the second driving assembly 70 is disposed at the output end of the first driving assembly 30, the first driving assembly 30 drives the second driving assembly 70 to further drive the storage tank 10 and the coating member 20 to move along the coating direction, and the second driving assembly 70 directly drives the storage tank 10 and the coating member 20 to approach or depart from the object to be coated.

When the flux is applied to the object to be coated or added to the storage tank 10, the flux may overflow through the first through hole 12, and in order to prevent the flux from flowing out to other devices, the flux applying apparatus preferably further includes a first overflow groove 50, and an upper end of the first overflow groove 50 is open and can accommodate the storage tank 10, and has a certain length.

In one embodiment, the first overflow groove 50 is disposed along the coating direction and has a certain length, the guiding element 32 is preferably a guide rod disposed in the first overflow groove 50, the guide rod is suspended in the first overflow groove 50, the bottom of the storage groove 10 is provided with a sliding groove, the sliding groove is sleeved on the guiding element 32 and is slidably connected with the guiding element 32, and the first driving element 31 is connected with and drives the storage groove 10 to slide along the guiding element 32. Because the guide member 32 is suspended, when the first overflow groove 50 receives overflowing soldering flux, the soldering flux does not directly contact the guide member 32, and as long as the overflowing soldering flux is cleaned in time, the soldering flux does not corrode or affect the guide member 32. In addition, the overflow groove 50 of the embodiment of the invention has a larger bottom area, so that more soldering flux can be accommodated, and the height of the soldering flux is lower, so that the soldering flux is not easy to contact the guide piece 32, and the soldering flux is prevented from corroding the guide piece 32.

In this embodiment, the storage tank 10 is provided in the first overflow tank 50, and as a modification, the storage tank 10 may be provided above the first overflow tank 50.

In this embodiment, the first driving member 31 is disposed outside the first overflow tank 50, and the output end of the first driving member 31 is connected to the sidewall of the storage tank 10 through a connection plate. To reduce the equipment footprint, the first drive member 31 is preferably a rodless cylinder.

In other embodiments, the first overflow channel 50 can be slidably coupled to the guide 32. At this time, the storage tank 10 is relatively fixedly disposed in the first overflow tank 50, and the first driving member 31 is connected to and drives the first overflow tank 50 to move along the guide member 32, so as to drive the storage tank 10 and the coating member 20 to coat in the coating direction.

Since the flux is used less and less, it is troublesome to remove the cover plate 11 and then pour the flux each time. As a preferable mode, as shown in fig. 3, the soldering flux applying apparatus further includes a liquid injecting component 60, and the liquid injecting component 60 is used for injecting the soldering flux into the reservoir 10.

In one embodiment, the priming assembly 60 includes a conduit 63 for communicating the reservoir 10 with a priming machine (not shown), and the conduit 63 for connecting the priming machine to the reservoir 10 is provided with a timing valve (not shown). Specifically, the side wall of the storage tank 10 is communicated with a first joint 61, one end of the pipeline 63 is communicated with the first joint 61, the other end of the pipeline is communicated with an external liquid injection machine, and the scaling powder in the liquid injection machine can be input into the storage tank 10 in a timed and quantitative mode through automatic opening and closing of a system control timing valve, so that automatic liquid injection is achieved.

In another embodiment, as shown in fig. 3, the liquid injection assembly 60 includes a liquid storage tank 64, the liquid storage tank 64 is communicated with the storage tank 10, the liquid storage tank 64 is communicated with the atmosphere, and the liquid storage tank 64 injects the soldering flux into the storage tank 10 by using the liquid level difference. Specifically, the reservoir 64 is open on one side (top open or side open) to communicate with the atmosphere; meanwhile, the liquid storage tank 64 is communicated with the storage tank 10 through a pipeline 63, a second connector 62 is arranged on one side of the liquid storage tank 64, a first connector 61 is arranged on one side of the storage tank 10, and the pipeline 63 is communicated with the first connector 61 and the second connector 62 to communicate the liquid storage tank 64 with the storage tank 10, so that the liquid storage tank 64 and the storage tank 10 form a communicating device, and when the liquid level in the liquid storage tank 64 is higher than that in the storage tank 10 according to the siphon effect, the soldering flux in the liquid storage tank 64 can enter the storage tank 10 along the pipeline 63. That is, as flux in the reservoir 10 decreases with use, the level of the liquid within the reservoir 10 decreases, and the flux in the reservoir 64 may actively flow into the reservoir 10.

Further, to ensure a continuous supply of flux, the reservoir 64 communicates with an external liquid injector. Meanwhile, a solenoid valve (not shown) is arranged on a pipeline of the liquid injection machine connected with the liquid storage tank 64. The filling machine is connected to the reservoir 64 via a solenoid valve. After the electromagnetic valve is opened, the liquid injection machine can introduce the soldering flux into the liquid storage tank 64 until the liquid levels in the liquid storage tank 64 and the storage tank 10 reach the highest position, namely the storage tank 10 is filled with the soldering flux, then the electromagnetic valve is closed, and when the soldering flux in the storage tank 10 is not enough to be used, the electromagnetic valve is opened.

Further, the reservoir 64 is provided with a detection member 65 for detecting the liquid level therein. As a modification, the detection member 65 may be provided on the reservoir tank 10 for detecting the liquid level inside thereof. The detection member 65 is specifically used to detect the lowest level of the reservoir 64 or the reservoir 10, i.e., "when the flux in the reservoir 10 is not sufficiently used" as described above. At this time, the detection part 65 may feed back information to the control system, and the control system controls the opening of the electromagnetic valve, so that the external liquid injection machine introduces the soldering flux into the liquid storage tank 64. It should be noted that, because the reservoir 64 and the storage tank 10 achieve the active flow of the soldering flux through the siphon effect, that is, the liquid levels in the reservoir 64 and the storage tank 10 are at the same height at all times during the actual use.

Further, an overflow joint 66 is provided on the side wall of the reservoir 64, the overflow joint 66 being located at a position above the level of fluxing agent in the reservoir 10. After the electromagnetic valve is opened, the liquid injection machine injects the soldering flux into the liquid storage tank 64 until the liquid levels in the liquid storage tank 64 and the storage tank 10 reach the highest position. In some cases, flux may be added, resulting in a higher level in the reservoir 64 than the highest level that the reservoir 10 can receive, which is not practical. Thus, the overflow connection 66 is arranged above the maximum liquid level, and when flux is increased, the excess flux can flow out through the overflow connection 66. In one embodiment, as shown in fig. 3, the overflow joint 66 may be connected to the first overflow groove 50 through a pipe, so that the excessive soldering flux directly flows into the first overflow groove 50, thereby facilitating the recycling of the soldering flux. In other embodiments, the overflow joint 66 may be connected to other fluid storage devices via a pipe.

In this embodiment, the conduit 63 communicating between the first connector 61 and the second connector 62 is a hose, and the first driving assembly 30 or the second driving assembly 70 can drive the reservoir tank 10 to move, while the reservoir tank 64 remains stationary. As a variation, the tube 63 may be a length of rigid tubing, and the first drive assembly 30 or the second drive assembly 70 may move the reservoir 10 and, at the same time, the reservoir 64.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
