Technical Field

[0001] The utility model relates to the technical field of LED circuit board welding equipment, in particular to a reflow soldering equipment for LED light strips. Background Art

[0002] An LED lamp is a semiconductor material chip that emits light at an electrode. The PCB board and the chip of an LED light strip usually need to be welded by a reflow soldering machine. The reflow soldering furnace is a welding equipment in the SMT industry. It can provide an automatic and stable heating environment, making the solder paste in the furnace heated and melted, so that the electrical components pre-mounted on the PCB board of the LED lamp and the PCB board are reliably combined through a solder alloy. After the welding is completed, the PCB board needs to be cooled and then taken out.

[0003] However, in actual use of the prior art, once a failure occurs and the machine stops for maintenance, since it takes a certain amount of time for the reflow soldering equipment to heat up after stopping, generally the reflow soldering equipment does not stop during short-term failures, which will cause the LED light strip inside the reflow soldering equipment to be damaged due to being stagnant in a high-temperature environment.

The number of the heat dissipation copper plates 11 is several, and several heat dissipation copper plates 11 are divided into two groups and are respectively arranged at the front and rear ends inside the reflow soldering main body 1 to form two reflow soldering production lines. The power of several heat dissipation copper plates 11 increases sequentially along the moving direction of the LED light strip, so that the waste heat is first used for heating and soldering during the movement of the LED light strip. And an electric heating plate 10 for generating high temperature is arranged between the second heat insulation plate 9 and the heat dissipation copper plate 11;

[0028] When the above structure is in use, the LED light strip is first passed through between the upper heating assembly and the lower heating assembly, and then the LED light strip is pulled. At the same time, the heating box 3 and the electric heating plate 10 are powered on to work. The heating box 3 is located at the top of the LED light strip to heat the surface of the LED light strip. At the same time, the electric heating plate 10 is located at the bottom of the LED light strip. The electric heating plate 10 heats the heat dissipation copper plate 11, and the temperature distribution is made uniform through the heat dissipation copper plate 11, so that the heat dissipation copper plate 11 can uniformly transfer heat to the bottom of the LED light strip, thereby performing soldering operation on the LED light strip.

[0029] By setting the second heat insulation plate 9 and the fixing frame 8, the downward transfer of temperature can be isolated to prevent damage to the cylinder 7. A fixing plate 13 is fixedly installed on the surface of the cylinder 7. A first support frame 12 is fixedly installed at the bottom of the fixing plate 13, and the first support frame 12 is fixedly installed in the middle of the reflow soldering main body 1. A second support frame 14 is fixedly installed at the top of the cylinder 7, and a support plate 15 is fixedly installed on the surface of the second support frame 14. Both the second support frame 14 and the support plate 15 are fixedly installed at the bottom of the fixing frame 8.

[0030] The heat insulation assembly includes a sprocket 4 rotatably connected to the middle of the reflow soldering main body 1 through a bearing. A chain 5 is meshed on the surface of the sprocket 4. A first heat insulation plate 6 is fixedly installed at the top of the chain 5 through a bracket, and the first heat insulation plate 6 is located between the heating box 3 and the heat dissipation copper plate 11. The sprocket 4 is driven by a driving motor;

[0031] When shutdown maintenance is required, the drive motor drives the sprocket 4 to rotate at this time, and the sprocket 4 drives the first heat insulation plate 6 to drive through the chain 5, so that the first heat insulation plate 6 moves from the unheated area to the heating and welding area, that is, the first heat insulation plate 6 moves to the position between the heating box 3 and the heat equalizing copper plate 11, so as to isolate the high temperature generated by the heating box 3. At the same time, the cylinder 7 drives the fixed frame 8 to move downward through the second support frame 14 and the support plate 15, and then the fixed frame 8 drives the electric heating plate 10 and the heat equalizing copper plate 11 to move downward through the second heat insulation plate 9, changing the distance between the heat equalizing copper plate 11 and the LED light strip, that is, reducing the temperature of the heat equalizing copper plate 11 heating the LED light strip, so as to avoid the occurrence of high temperature damage to the LED light strip in a stagnant state.

[0032] A plurality of guide wheels 16 are fixedly installed in the middle of the first heat insulation plate 6, and a guide rail 17 is fixedly installed at the top of the reflow soldering main body 1 corresponding to the position of the guide wheel 16, so that the guide rail 17 guides the rolling of the guide wheel 16. The guide wheel 16 includes an inverted T-shaped frame and rollers, and the rollers are rotatably connected to both ends of the bottom of the T-shaped frame. The T-shaped frame is fixedly embedded in the middle of the first heat insulation plate 6, and the width between the rollers is adapted to the width of the guide rail 17. The first heat insulation plate 6 is lifted by the T-shaped frame and the rollers, so that the LED light strip penetrates through the bottom of the first heat insulation plate 6. By arranging the guide wheel 16 and the guide rail 17, the first heat insulation plate 6 can move smoothly between the heating box 3 and the heat equalizing copper plate 11, so as to effectively isolate the high temperature generated by the heating box 3 from the LED light strip.

[0033] Working principle: When in use, the utility model first passes the LED light strip through between the upper heating component and the lower heating component, and then the LED light strip is pulled. At the same time, the heating box 3 and the electric heating plate 10 are powered on and work. The heating box 3 is located at the top of the LED light strip to heat the surface of the LED light strip. At the same time, the electric heating plate 10 is located at the bottom of the LED light strip. The heat equalizing copper plate 11 is heated by the electric heating plate 10, and the temperature distribution is made uniform through the heat equalizing copper plate 11, so that the heat equalizing copper plate 11 can uniformly transfer heat to the bottom of the LED light strip, so as to perform welding operation on the LED light strip;

[0034] When shutdown maintenance is required, the drive motor drives the sprocket 4 to rotate, and the sprocket 4 drives the first heat insulation plate 6 to drive through the chain 5, so that the first heat insulation plate 6 moves from the unheated area to the heating and welding area, that is, the first heat insulation plate 6 moves to the position between the heating box 3 and the heat equalizing copper plate 11, thereby isolating the high temperature generated by the heating box 3. At the same time, the cylinder 7 drives the fixing frame 8 to move downward through the second support frame 14 and the support plate 15, and then the fixing frame 8 drives the electric heating plate 10 and the heat equalizing copper plate 11 to move downward through the second heat insulation plate 9, changing the distance between the heat equalizing copper plate 11 and the LED light strip, that is, reducing the temperature of the heat equalizing copper plate 11 heating the LED light strip, so as to avoid the occurrence of high temperature damage to the LED light strip in a stagnant state;

[0035] By setting the second heat insulation plate 9 and the fixing frame 8, the downward transfer of temperature can be isolated, preventing damage to the cylinder 7. By setting the guide wheel 16 and the guide rail 17, the first heat insulation plate 6 can move smoothly between the heating box 3 and the heat equalizing copper plate 11, thus effectively isolating the high temperature generated by the heating box 3 from the LED light strip.
