For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] The utility model embodiment provides a highly efficient curing device for coated solder strips, comprising:

[0029] A condenser 1, wherein the condenser 1 comprises a condensation inlet 1a and a condensation outlet;

[0030] A heat curing tube 2, wherein the heat curing tube 2 comprises a heat curing inlet and a heat curing outlet 2a, and the heat curing outlet 2a is connected and communicated with the condensation inlet 1a;

[0031] The cold and hot gas supply device 3 includes a cold supply end 31 and a hot supply end 32 . The cold supply end 31 is connected and communicated with the condensing tube 1 , and the hot supply end 32 is connected and communicated with the heat curing tube 2 .

[0032] In a specific embodiment, Figure 1As shown, the condenser tube 1 and the heat curing tube 2 are arranged in sequence from top to bottom, the upper end of the condenser tube 1 is the condensation outlet, and the lower end is the condensation inlet 1a, the upper end of the heat curing tube 2 is the heat curing outlet 2a, and the lower end is the heat curing inlet, the upper end of the heat curing tube 2 is connected to the lower end of the condenser tube 1, the heating end 32 can be connected to the heat curing inlet or the heat curing outlet 2a, the cooling end 31 can be connected to the inlet of the condenser tube 1 or the condensation outlet, and then the hot and cold gas supply device 3 can fill hot gas into the heat curing tube 2 and fill cold air into the condenser tube 1.

[0033] During operation, the soldering tape passes through the heat curing tube 2 and the condensing tube 1 in sequence from bottom to top. The high-temperature airflow in the heat curing tube 2 can quickly dry the solvent of the liquid on the surface of the soldering tape, so that the coating film layer is dried and cured. The low-temperature airflow in the condensing tube 1 can quickly reduce the temperature of the coating film layer, so that the resin of the coating film layer hardens quickly and the hardness of the coating film layer is improved, thereby reducing the loss of the coating film layer due to friction with the guide wheel in subsequent operation and improving the quality of the coating film layer.

[0034] The type of the cold and hot gas supply device 3 is not limited. In a specific embodiment, the cold and hot gas supply device 3 is a vortex cold and hot separation tube, and the vortex cold and hot separation tube includes a vortex chamber 33. The cold supply end 31 is arranged at one end of the vortex chamber 33, and the heat supply end 32 is arranged at the other end of the vortex chamber 33. The side of the vortex chamber 33 is also provided with an air inlet, such as Figure 1 As shown, the heat curing tube 2 and the condensing tube 1 are arranged in series, and then arranged in parallel with the vortex cold and hot separation tube. Gas is input from the air inlet, and the gas generates cold air and hot air in the vortex chamber 33. The cold air is output from the cold supply end 31 and input to the condensing tube 1, and the hot air is output from the heating end 32 and input to the heat curing tube 2. The number of outlets of the cold supply end 31 and the number of outlets of the heating end 32 is not limited. The vortex cold and hot separation tube can be provided with one outlet of the cold supply end 31 and three outlets of the heating end 32. The overall structure of the present application is simple, compact, and occupies little space.

[0035] The temperature of the heat curing tube 2 and the condensing tube 1 in the present application needs to be reasonably designed. If the temperature of the heat curing tube 2 is too high, the internal components of the coating film layer will be thermally decomposed, and if the temperature is too low, the thermal curing efficiency will be low. Therefore, the temperature of the heat curing tube 2 is 70℃~90℃. At the same time, the temperature of the condensing tube 1 is -10℃~0℃, which is conducive to rapid cooling of the coating film layer and hardening of the resin of the coating film layer.

[0036] Furthermore, the cold flow rate of the vortex hot and cold separation tube is set to 0.2-0.4.

[0037] And / or, the air inlet pressure of the vortex hot and cold separation tube is 0.2-0.6 MPa. The cold flow rate of the vortex hot and cold separation tube can be adjusted according to different ambient temperatures, and the air inlet pressure of the air inlet can be adjusted to control the temperature of the cold air output from the cooling end 31 and the hot air output from the heating end 32 to meet the requirements.

[0038] Furthermore, the length of the vortex hot and cold separation tube is 30 to 60 cm;

[0039] And / or, the length of the heat curing tube 2 is 150 to 250 cm;

[0040] And / or, the length of the condenser 1 is 60-100 cm.

[0041] Furthermore, thermal insulation cotton is provided on the outside of the thermal curing tube 2 and / or the condensing tube 1, and the thermal insulation cotton can make the temperature distribution of the thermal curing tube 2 and the condensing tube 1 more uniform, which is beneficial to improving the effect of thermal curing treatment and condensation treatment of the welding strip.

[0042] Furthermore, it also includes a hot air knife 4, which is arranged between the heat curing tube 2 and the condensing tube 1, and the hot air knife 4 is connected and communicated with the heating end 32 of the vortex hot and cold separation tube. Figure 1 As shown, the heating end of the vortex hot and cold separation tube is provided with three outlets, two outlets are connected and communicated with the hot air knife 4, and the other outlet is connected and communicated with the heat curing tube 2. This structure can greatly save the occupied space of the coated solder strip efficient curing device and save processes.

[0043] Furthermore, the coated solder strip high-efficiency curing device further comprises a coating mechanism 5, the coating mechanism 5 is connected to the heat curing inlet of the heat curing tube 2, and the coating speed of the coating mechanism 5 is greater than or equal to 150 m / min. The coating method in this application is not limited, and the surface of the solder strip can be coated by dipping, spraying, electrostatic deposition, etc. Compared with the existing fan curing method, the coated solder strip high-efficiency curing device in this application has a significantly improved coating speed, thereby greatly improving production efficiency.

[0044] Furthermore, the coated weld strip efficient curing device also includes a pre-coating air knife 6, which is arranged between the coating mechanism 5 and the thermal curing tube 2. The pre-coating air knife 6 can adjust the thickness of the coating film layer of the weld strip and make the surface of the coating film layer smoother and more uniform, which is beneficial to the subsequent thermal curing treatment.

[0045] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
