TECHNICAL FIELD

[0001] The utility model relates to two ware production technical field, concretely relates to a kind of soldering flux anti-crystallization device. BACKGROUND

[0002] When the elbow of the automatic welding condenser and evaporator assembly is welded, the flame used for welding needs to add soldering flux, which can remove the surface oxide film of the base material, help the solder flow, reduce the surface stress of the base material, ensure the penetration of the solder to the base material and improve the welding penetration depth. That is, during the welding process of the two-component assembly elbow, the flame needs to add soldering flux to heat the base material, remove the surface oxide film of the base material to help the solder flow, prevent the base material impurities or oxide film from affecting the penetration of the solder to the base material, avoid the formation of a leakage channel due to insufficient penetration of the weld seam solder, causing the air conditioner two-component assembly system to leak fluorine, resulting in the air conditioner unable to operate.

[0003] Currently, the soldering flux tank of the two-component workshop welding line is placed on site. In winter, when the temperature is below zero, the adhesive in the soldering flux will crystallize, damaging the structure of the soldering flux and affecting the quality of the soldering flux. The crystallized soldering flux cannot effectively remove the surface oxide film of the base material during the welding process, affecting the penetration of the solder to the base material, and the weld seam is prone to sand eye leakage channel, causing the air conditioner system to leak fluorine and the air conditioner to be unable to cool or heat.

[0044] Embodiment 1

[0045] When the elbow of the condenser and evaporator assembly is automatically welded, the welding flame needs to add flux, which can remove the surface oxide film of the base material, help the solder flow, reduce the surface stress of the base material, ensure the penetration of the solder to the base material, and improve the welding penetration. That is, during the welding process of the elbow of the two-component assembly, the flame needs to add flux to heat the base material, remove the surface oxide film of the base material to help the solder flow, prevent the base material impurities or oxide film from affecting the penetration of the solder to the base material, avoid the formation of a leakage channel due to insufficient penetration of the weld solder, causing the air conditioner two-component assembly system to leak fluorine, and resulting in the air conditioner unable to operate.

[0046] Currently, the flux tank of the two-component workshop welding line is placed on site. In winter, when the temperature is below zero, the adhesive in the flux will crystallize, destroying the structure of the flux molecules and affecting the quality of the flux. The crystallized flux affects the penetration of the solder to the base material during the welding process, and the weld is prone to sand holes and leakage channels, resulting in air conditioner system fluorine leakage and the air conditioner being unable to cool or heat.

[0047] To this end, the flux anti-crystallization device disclosed in the present embodiment, please refer to Figures 1-5 , comprising:

[0048] a container 1,

[0049] Exemplarily, the container 1 can be a box,

[0050] a tank 2 containing flux, the tank 2 being placed in the container 1, the container 1 being filled with a heat-conducting medium, and the tank 2 being heated by the heat-conducting medium,

[0051] Generally, the flux is loaded in the tank 2, which can store the welding agent. Since the heat-conducting medium is filled in the container 1, and the tank 2 containing the flux is placed in the container 1, the heat-conducting medium in the container 1 can heat the flux in the tank 2,

[0052] a heat-conducting pipe 8 through which the heat-conducting medium circulates between an electric welding room 4 and the container 1, the heat-conducting medium being heated by the residual heat in the electric welding room 4, and the heat of the heat-conducting medium being transmitted to the flux in the tank 2.

[0053] The heat-conducting pipe 8 can circulate the heat-conducting medium to the electric welding room 4 and the container 1, so as to bring the residual heat in the electric welding room 4 to the container 1 to heat the tank 2 in the container 1, avoiding the crystallization of the heat-conducting medium in the container 1.

[0054] Specifically,

[0055] The tank 2 is used to load flux, so as to store and use. The container 1 is filled with heat-conducting medium, which can conduct heat. The tank 2 is placed in the container 1 and surrounded by the heat-conducting medium. The main function of the heat-conducting medium is to transfer heat from the electric welding room 4 to the flux in the tank 2. The electric welding room 4 generates waste heat during the welding process, which is used to heat the heat-conducting medium. The heat-conducting pipe 8 connects the electric welding room 4 and the container 1, so that the heat-conducting medium can circulate between the two. After the heat-conducting medium is heated in the electric welding room 4, it transfers heat to the flux in the container 1 through the heat-conducting pipe 8. The heat-conducting medium absorbs waste heat in the electric welding room 4 and then circulates back to the container 1 through the heat-conducting pipe 8 to transfer heat to the flux in the tank 2, so as to maintain the temperature of the flux and prevent it from crystallizing.

[0056] Since the flux may crystallize at low temperature, affecting the welding effect, the system maintains the temperature of the flux by circulating the heat-conducting medium, so as to avoid crystallization.

[0057] In this embodiment, the heat-conducting medium is tap water.

[0058] The tap water has good heat capacity and good flowability.

[0059] In this embodiment, the circulating pump 5 and the temperature controller 6 are further included, the power plug of the circulating pump 5 is connected with the temperature controller 6,

[0060] The circulating pump 5 drives the heat-conducting medium in the heat-conducting pipe 8 to circulate through the electric welding room 4 and the container 1, and the temperature controller 6 detects the temperature of the heat-conducting medium in the container 1 and controls the power connection state of the power plug.

[0061] In use, the circulating pump 5 is used to drive the heat-conducting medium to flow through the electric welding room 4 and the container 1, the electric welding room 4 heats the heat-conducting medium, and the container 1 effectively maintains the heating effect of the heat-conducting medium by using the heat of the heat-conducting medium. The temperature controller 6 is used to detect the temperature of the heat-conducting medium in real time. When the temperature of the heat-conducting medium is lower than the set threshold, the temperature controller 6 connects the power plug of the circulating pump 5, so that the circulating pump 5 drives the heat-conducting medium to circulate, so that the heat-conducting medium is heated by the waste heat of the electric welding room 4. When the temperature controller 6 detects that the temperature of the heat-conducting medium reaches the set temperature, the temperature controller 6 controls the circulating pump 5 to disconnect the power supply at this time. At this time, the heat of the heat-conducting medium in the container 1 can be used to avoid unnecessary consumption of circulating power.

[0062] Specifically,

[0063] The circulation pump 5 is used to drive the circulation of the heat-conducting medium in the heat-conducting pipe 8. It is connected to the temperature controller 6, and its power supply connection state is controlled by the temperature controller 6. The temperature controller 6 is responsible for detecting the temperature of the heat-conducting medium in the container 1, and controlling the power supply connection state of the power plug of the circulation pump 5 according to the detection result.

[0064] When the temperature controller 6 detects that the temperature of the heat-conducting medium is lower than the preset threshold value, it will connect the power plug of the circulation pump 5 to make the circulation pump 5 work, driving the circulation of the heat-conducting medium between the electric welding room 4 and the container 1. The residual heat in the electric welding room 4 heats the heat-conducting medium, which then transfers heat to the tank 2 in the container 1, maintaining the temperature of the flux.

[0065] When the temperature of the heat-conducting medium reaches the preset temperature, the temperature controller 6 will disconnect the power supply of the circulation pump 5 to stop the circulation. At this time, the heat-conducting medium in the container 1 can use its own heat to maintain the temperature of the flux, avoiding unnecessary energy waste.

[0066] Through the intelligent control of the temperature controller 6, the system can stop the work of the circulation pump 5 when additional heating is not needed, thereby saving energy.

[0067] This design ensures that the temperature of the heat-conducting medium is always within the appropriate working range, helping to maintain the fluidity of the flux and the welding quality.

[0068] The whole system is driven by automatic temperature control and circulation pump 5, reducing manual intervention and improving the convenience and efficiency of operation.

[0069] In this embodiment, the electric welding room 4 is provided with a fire rack 7, and the heat-conducting pipe 8 is arranged on the fire rack 7.

[0070] The electric welding room 4 is provided with a fire rack 7 to place related welding guns and devices to be welded, so that the heat-conducting pipe 8 is directly arranged on the fire rack 7, so that the electric welding room 4 can fully heat the heat-conducting pipe 8 arranged on the rack.

[0071] Specifically, the fire rack 7 is a structure within the electric welding house 4 for placing the welding gun and the device to be welded. The heat pipe 8 is erected on the fire rack 7, which design enables the heat pipe 8 to directly contact the heat within the electric welding house 4. This layout of the heat pipe 8 can maximize the use of the waste heat generated within the electric welding house 4, improving the thermal efficiency. Erecting the heat pipe 8 directly on the fire rack 7 can ensure that the heat pipe 8 fully absorbs the heat within the electric welding house 4, because the fire rack 7 is close to the welding area and is a place where heat is concentrated. This layout helps the heat medium to quickly heat up, thereby more effectively transferring heat to the flux in the container 1. This layout of the heat pipe 8 also facilitates installation and maintenance, because the fire rack 7 is usually designed as an easily accessible structure, which facilitates technicians to carry out necessary inspection and maintenance. Erecting the heat pipe 8 on the fire rack 7 can avoid the heat pipe 8 directly contacting the ground or other objects that may cause damage, reducing the risk of accidental damage. This layout also helps to optimize the space utilization within the electric welding house 4, because the integrated design of the heat pipe 8 and the fire rack 7 can reduce additional space occupation.

[0072] In this embodiment, the heat pipe 8 is coiled and distributed in the internal space of the electric welding house 4.

[0073] By coiling and distributing the heat pipe 8 throughout the electric welding house 4, the heat pipe 8 can fully contact the waste heat within the entire electric welding house 4, improving the heating effect of the waste heat within the electric welding house 4 on the heat pipe 8.

[0074] In this embodiment, the heat pipe 8 is a stainless steel heat pipe 8.

[0075] The stainless steel heat pipe 8 has good strength and good heat transfer effect.

[0076] In this embodiment, the temperature of the electric welding house 4 is 2000℃-3000℃.

[0077] The electric welding house 4 generates a lot of heat during the welding process, which can heat the heat medium well. Embodiment

[0078] When automatically welding the elbow of the condenser and evaporator assembly, the welding flame needs to add flux, which can remove the oxide film on the base material surface, help the solder to flow, reduce the surface stress of the base material, ensure the penetration of the solder to the base material, and improve the welding penetration. That is, during the welding process of the elbow of the two-device assembly, the flame needs to add flux to heat the base material, remove the oxide film on the base material surface, help the solder to flow, prevent the base material impurities or oxide film from affecting the penetration of the solder to the base material, avoid insufficient penetration of the solder in the weld to form a leakage channel, and cause the air conditioner two-device assembly system to leak fluorine, resulting in the air conditioner unable to operate.

[0079] At present, the flux tank of the welding line in the two-plant workshop is placed on site, and the temperature is lower than zero in winter. The adhesive in the flux can crystallize, which destroys the structure molecule of the flux and affects the quality of the flux. The crystallized flux affects the penetration of the solder on the base material during the welding process, and the weld is prone to sand eye leakage channels, which causes the air conditioning system to leak fluorine, and the air conditioner cannot cool or heat.

[0080] To this end, the device welding method of the present embodiment uses a flux anti-crystallization device, which is described below Figures 1-5 , comprising:

[0081] a container 1,

[0082] Exemplarily, the container 1 can be a box,

[0083] a tank 2 containing flux, the tank 2 being placed in the container 1, the container 1 being filled with a heat-conducting medium, and the tank 2 being heated by the heat-conducting medium,

[0084] Generally, the flux is loaded in the tank 2, which can store the welding agent. Since the heat-conducting medium is filled in the container 1, and the tank 2 containing the flux is placed in the container 1, the heat-conducting medium in the container 1 can heat the flux in the tank 2,

[0085] a heat-conducting pipe 8 through which the heat-conducting medium circulates between the electric welding room 4 and the container 1, the residual heat in the electric welding room 4 heating the heat-conducting medium, and the heat of the heat-conducting medium being transmitted to the flux in the tank 2.

[0086] The heat-conducting pipe 8 can circulate the heat-conducting medium to the electric welding room 4 and the container 1, so as to bring the residual heat in the electric welding room 4 to the container 1 to heat the tank 2 in the container 1, avoiding crystallization of the heat-conducting medium in the container 1.

[0087] In the present embodiment, the heat-conducting medium is tap water.

[0088] The tap water has good heat capacity and good flowability.

[0089] The present embodiment further comprises a circulating pump 5 and a temperature controller 6, the power plug of the circulating pump 5 being connected to the temperature controller 6,

[0090] the circulating pump 5 driving the heat-conducting medium in the heat-conducting pipe 8 to circulate between the electric welding room 4 and the container 1, and the temperature controller 6 detecting the temperature of the heat-conducting medium in the container 1 and controlling the power connection state of the power plug.

[0091] In use, the circulating pump 5 is used to drive the heat-conducting medium to flow through the electric welding room 4 and the container 1, the electric welding room 4 is used to heat the heat-conducting medium, and the container 1 is used to effectively maintain the heating effect of the heat-conducting medium by using the heat of the heat-conducting medium, wherein the temperature controller 6 is used to detect the temperature of the heat-conducting medium in real time, and when the temperature of the heat-conducting medium is lower than the set threshold value, the temperature controller 6 is connected to the power connection of the circulating pump 5, so that the circulating pump 5 drives the heat-conducting medium to flow in a circulating manner, so that the heat-conducting medium is heated by the residual heat of the electric welding room 4. When the temperature controller 6 detects that the temperature of the heat-conducting medium reaches the set temperature, the temperature controller 6 controls the circulating pump 5 to disconnect the power supply at this time, and the heat of the heat-conducting medium in the container 1 can be used to avoid unnecessary consumption of circulating power.

[0092] In the embodiment, the fire rack 7 is arranged in the electric welding room 4, and the heat-conducting pipe 8 is arranged on the fire rack 7.

[0093] The fire rack 7 is arranged in the electric welding room 4 to place the related welding gun and the device to be welded, and therefore, the heat-conducting pipe 8 is directly arranged on the fire rack 7, so that the electric welding room 4 can sufficiently heat the heat-conducting pipe 8 arranged on the fire rack 7.

[0094] In the embodiment, the heat-conducting pipe 8 is arranged in the internal space of the electric welding room 4 in a coiled manner.

[0095] By arranging the heat-conducting pipe 8 in the electric welding room 4 in a coiled manner, the heat-conducting pipe 8 can sufficiently contact the residual heat in the entire electric welding room 4, and the heating effect of the residual heat in the electric welding room 4 on the heat-conducting pipe 8 is improved.

[0096] In the embodiment, the heat-conducting pipe 8 is a stainless steel heat-conducting pipe 8.

[0097] The stainless steel heat-conducting pipe 8 has good strength and good heat transfer effect.

[0098] In the embodiment, the temperature of the electric welding room 4 is 2000℃-3000℃.

[0099] The electric welding room 4 generates a large amount of heat during the electric welding process, and the heat can be used to heat the heat-conducting medium

[0100] When the ambient temperature is lower than 0℃, the soldering flux anti-crystallization device is used, the tank 2 containing the soldering flux is arranged in the container 1, the heat-conducting medium is introduced into the container 1, the heat-conducting medium flows through the electric welding room 4 through the heat-conducting pipe 8, the residual heat in the electric welding room 4 heats the heat-conducting medium, and then the heat-conducting medium heats the soldering flux to prevent the soldering flux from crystallizing, and the soldering flux is used to weld the device.

[0101] The ambient temperature is below zero Celsius, which has a greater possibility to cause the flux to crystallize. Therefore, when the ambient temperature is below zero Celsius, the heat-conducting medium is used to heat the flux in the tank 2. Before welding, the flux is injected into the container 1, and the heat-conducting medium in the container 1 heats the tank 2. The heating temperature continuously heats the flux, so that the flux can stably keep from crystallizing. During the welding process, the heated flux is used for welding, which ensures the welding effect.

[0102] According to the device welding method as described above, when the temperature of the heat-conducting medium is lower than T1, which is the minimum temperature, the heat-conducting medium is driven to flow through the electric welding house 4. When the temperature of the heat-conducting medium reaches T2, which is the set heating temperature, the driving of the heat-conducting medium to flow is stopped.

[0103] By monitoring whether the heat-conducting medium reaches the minimum temperature, the flux is heated in time, which ensures that the flux will not crystallize. At the same time, when the temperature is higher than the set temperature, the heating is stopped to avoid the heat-conducting medium being too high in temperature and affecting the performance.

[0104] For example, T1 is 20°C, and T2 is 80°C.

[0105] The device is a condenser or an evaporator.

[0106] Specifically,

[0107] When the temperature of the heat-conducting medium is lower than T1 (the minimum temperature), the system drives the heat-conducting medium to flow through the electric welding house 4 for heating. This step ensures that the temperature of the heat-conducting medium and the flux will not be too low, preventing the flux from crystallizing and affecting the welding effect.

[0108] Stop heating when reaching T2: When the temperature of the heat-conducting medium reaches T2 (the set heating temperature), the system stops driving the heat-conducting medium to flow. This step avoids the heat-conducting medium being too high in temperature, which may affect its performance or cause other problems.

[0109] For example, T1 is 20°C, and T2 is 80°C, which means that when the temperature of the heat-conducting medium is lower than 20°C, the system starts heating, and the temperature will not exceed 80°C.

[0110] This temperature control strategy can accurately manage the temperature of the heat-conducting medium, ensuring that the temperature of the flux during the welding process is always in the best working state. By avoiding excessive heating, energy waste can be reduced, and the energy efficiency of the system can be improved. By preventing the temperature from being too low, crystallization of the flux can be prevented, and the welding quality can be ensured.
