DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0030] At present, a flux recovery device is usually provided in a reflow furnace to recover the flux. When the flux recovery device is used for a long time, the flux recovery pipeline in the flux recovery device needs to be cleaned and maintained to avoid the flux sticking and clogging in the flux recovery pipeline, thereby affecting the performance of the flux recovery.

[0031] However, the overall structure of the flux recovery equipment in the prior art is relatively complex, and the flux recovery pipeline is relatively long, so it is impossible to use an ultrasonic instrument of normal specifications to clean and maintain the flux recovery pipeline.

[0032] In order to solve the problem in the prior art that the flux recovery pipeline is difficult to clean and maintain due to its long length, an embodiment of the utility model provides a flux recovery pipeline.

[0033] A soldering flux recovery pipeline proposed in an embodiment of the utility model comprises a first pipeline, a second pipeline and at least one set of connecting components, and the first pipeline and the second pipeline are detachably connected through the connecting components.

[0034] The connecting component includes a first connecting member and a second connecting member. The first connecting member is arranged at one end of the first pipe, and the second connecting member is arranged at one end of the second pipe. The first pipe and the second pipe are connected through the first connecting member and the second connecting member.

[0035] The first pipe and the second pipe are detachably connected through a connecting assembly. When the flux recovery pipe needs to be used to recover the flux, the first pipe and the second pipe are connected using the connecting assembly; when the flux recovery pipe needs to be cleaned and maintained, the first pipe and the second pipe are disassembled through the connecting assembly so that the lengths of the first pipe and the second pipe are adapted to an ultrasonic instrument of normal specifications. Using an ultrasonic instrument of normal specifications to clean the flux recovery pipe improves the versatility of the flux recovery pipe for the ultrasonic instrument, reduces the cleaning cost and difficulty of the flux recovery pipe, and solves the problem in the prior art that the flux recovery pipe is difficult to clean and maintain due to its long length.

[0036] In some embodiments, the first connecting member may be a circular pipe, one end of which is connected to the first pipe, and the other end is provided with an annular protrusion along the circumference of the circular pipe, and at least one groove is provided on the annular protrusion. The second connecting member is correspondingly a circular pipe, one end of which is connected to the second pipe, and the other end is provided with an annular protrusion along the circumference of the circular pipe, and a clamping part adapted to the groove is correspondingly provided on the annular protrusion, and the clamping part on the second connecting member is clamped with the groove on the first connecting member to realize a detachable connection between the first pipe and the second pipe.

[0037] Furthermore, the soldering flux recovery pipeline provided in the embodiment of the utility model further includes a third pipeline, which is arranged between the first pipeline and the second pipeline. The third pipeline is connected to the first pipeline and the second pipeline through a connecting assembly.

[0038] A second connecting piece is provided at one end of the third pipeline, and the third pipeline is connected to the first pipeline through the second connecting piece; a first connecting piece is provided at the other end of the third pipeline, and the third pipeline is connected to the second pipeline through the first connecting piece.

[0039] When the length of the flux recovery pipeline is fixed, setting the first pipeline and the second pipeline may still not solve the problem that the pipeline cannot be cleaned and maintained by an ultrasonic instrument of normal specifications due to the pipeline being too long. The number of third pipelines and the lengths of the first pipeline, the second pipeline and the third pipeline are set according to actual conditions, so that the first pipeline, the second pipeline and the third pipeline can be cleaned and maintained by an ultrasonic instrument of normal specifications after being disassembled. The first pipeline and the third pipeline, the third pipeline and the third pipeline, and the third pipeline and the second pipeline are all detachably connected through a connecting component.

It also includes two sets of connection components 3, which are respectively arranged between the first pipeline 1 and the third pipeline 4 and between the third pipeline 4 and the second pipeline 2, so that the first pipeline 1 and the third pipeline 4 are detachably connected, and the third pipeline 4 and the second pipeline 2 are detachably connected.

[0041] Furthermore, a flux recovery pipeline proposed in an embodiment of the utility model also includes at least one flux connection port, and a first elastic member and a third connection member are sequentially arranged at one end of the flux connection port, and the first elastic member is used to adjust the position of the third connection member.

However, the flux connection port is usually made of a material with a high hardness such as stainless steel, and the third connection piece cannot be flexibly rotated for easy connection. Therefore, a first elastic piece is provided, and the first elastic piece is bent to change the angle between the third connection piece and the first elastic piece and the direction of the third connection piece for easy connection.

[0043] See also Figure 1 In the embodiment of the utility model, a flux recovery pipeline includes two flux connection ports 5, which are respectively arranged on the first pipeline 1 and the third pipeline 4.

The pipe connected to the flux connecting port 5 is correspondingly provided with the same annular protrusion, and the two annular protrusions are clamped and fixed by a clamp to achieve a detachable connection between the flux connecting port 5 and the pipe connected to the flux connecting port 5. The first elastic member 51 is an adjustable threaded body. By adjusting the first elastic member 51, the first elastic member 51 can be bent to change the angle between the third connecting member 52 and the first elastic member 51 and the direction of the third connecting member 52 for easy connection.

In order to facilitate the connection, a second elastic member and a third elastic member are respectively provided at one end of the first pipe and the second pipe. The angle and position of the fourth connecting member are changed by adjusting the second elastic member, so as to facilitate the connection between the first pipe and the flux recovery device. The angle and position of the fifth connecting member are changed by adjusting the third elastic member, so as to facilitate the connection between the second pipe and the flux recovery device.

[0047] See also Figure 1 In the embodiment of the utility model, the fourth connecting member 12 and the fifth connecting member 22 are annular protrusions arranged circumferentially along one end of the first pipe 1 and the second pipe 2, respectively. The same annular protrusions are arranged on the pipes corresponding to the first pipe 1 and the second pipe 2, and the two annular protrusions are clamped and fixed by a clamp to realize the detachable connection between the first pipe 1 and the flux recovery device and the detachable connection between the second pipe 2 and the flux recovery device.

[0048] The second elastic member 11 and the third elastic member 21 are both adjustable threaded bodies. By adjusting the second elastic member 11, the second elastic member 11 can be bent to change the angle between the fourth connecting member 12 and the second elastic member 11 and the direction of the fourth connecting member 12, so as to facilitate the connection between the first pipeline 1 and the flux recovery device. By adjusting the third elastic member 21, the third elastic member 21 can be bent to change the angle between the fifth connecting member 22 and the third elastic member 21 and the direction of the fifth connecting member 22, so as to facilitate the connection between the third pipeline 4 and the flux recovery device.

[0049] Furthermore, the connecting assembly also includes a fixing member, which is used to fix the first connecting member and the second connecting member.

[0050] It can be understood that the first connecting member and the second connecting member can be circular pipes with threads arranged circumferentially, and the fixing member can be a hollow cylinder with internal threads.

[0051] The first connecting piece is connected to one end of the first pipe close to the second pipe by welding; the second connecting piece is connected to one end of the second pipe close to the first pipe by welding.
