Description

Technical Field

[0001] This invention relates to a brazing and drying line, and more particularly to a flip-type brazing and drying line. Background Technology

[0002] Before brazing, a layer of flux needs to be sprayed onto the surface of each workpiece. Currently, the flux is applied manually, which takes a long time. To improve efficiency, workers directly place the workpieces into the flux storage box, causing the flux to adhere to the workpieces. This method easily leads to uneven flux application, resulting in flux waste. Furthermore, areas with excessive flux are difficult to weld. When workers place the workpieces into the flux storage box, they come into contact with the flux, which can pose a health hazard to workers over a long period. Summary of the Invention

The clamping drive motor 431 drives the clamping adjustment screw 432 to rotate, and the clamping adjustment inner screw tube 434 moves horizontally along with the clamping adjustment screw 432. The first and second hinge seats cause the adjusting rod 435 to push the connecting rod 436 to move towards the side of the workpiece to be coated. The clamping inner thread tube 437 and the clamping member 438 move with the connecting rod 436, thereby clamping the side of the workpiece to be coated. The swing drive motor 414 drives the swing U-shaped frame 415 to swing, and the platform support frame 420 and the platform conveying roller 421 move with the swing U-shaped frame, so that the workpiece to be coated is in an inclined state. The vibrator 440 drives the swing U-shaped frame 415 to vibrate, thereby shaking off the excess flux on the workpiece to be coated after soldering into the flux storage box 110. The drying conveying motor 523 drives the drying conveying roller 521 to rotate, which can transport the workpiece to be coated on the unloading side of the vibrating clamping device. Then, the hot circulating fan 510 dries the flux on the workpiece to be coated on the drying conveying roller 521.

[0040] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
