Abstract
Description
Technical Field
[0001] This invention relates to a flux spraying system and a spraying method thereof, and more particularly to a three-dimensional flux spraying system and a spraying method thereof. Background Technology
[0002] In brazing processes, flux application is a crucial preliminary step, as its quality directly affects the strength, sealing performance, and overall machining accuracy of the brazed joint. The core function of flux is to remove the oxide film from the workpiece surface to be welded and to form a protective film during the welding process, preventing re-oxidation and ensuring good wetting and bonding between the filler metal and the workpiece surface. With the increasing automation of industrial production, flux application is gradually shifting from manual to automated spraying equipment, effectively reducing labor intensity and improving coating uniformity.
[0003] However, current mainstream automated flux coating equipment still has significant technical shortcomings, making it difficult to meet the demands of high-efficiency and integrated production. Existing flux coating equipment generally adopts a horizontal spraying method, with the layout and movement trajectory of its spraying mechanism designed around the horizontal direction, enabling precise spraying only on the upper side of the workpiece. In actual production, when flux needs to be sprayed on both the upper and lower sides of the workpiece, existing equipment cannot complete the entire spraying process in one go. The upper side must be sprayed first, and then the workpiece must be manually flipped over for a second spraying on the lower side.
[0004] The aforementioned manual flipping process not only adds extra manual steps and increases labor costs, but more importantly, it severely restricts the improvement of production efficiency. During manual flipping, the continuous operation of the spraying equipment needs to be paused, and the equipment restarted after flipping is completed for a second spraying, resulting in a significant extension of the overall spraying cycle, making it difficult to adapt to large-scale, high-speed assembly line production scenarios. Furthermore, manual flipping may also cause damage or peeling of the already sprayed flux layer due to improper operation, or cause impurities to adhere to the workpiece surface, affecting the stability of the spraying quality. In addition, the poor consistency of manual flipping may lead to deviations in the spraying position on the upper and lower sides of the workpiece, further affecting the reliability of subsequent brazing processes.

The lifting drive circuit, the translation drive circuit, and the rotation drive circuit are all stepper motor drive circuits, used to perform step-by-step precise drive of the lifting drive motor 204, the translation drive motor 205, and the rotation drive motor 214, respectively.
[0047] In the three-dimensional flux spraying system disclosed in this invention, both the main controller and the slave controller adopt existing single-chip microcomputer control modules to achieve coordinated control of the system; the wireless communication module and the slave wireless communication module adopt existing wireless communication modules, such as ZigBee communication modules; the card reader 120 and the electronic tag 224 are set up in pairs to achieve near-range positioning information reading; the spraying solenoid valve 222 adopts existing electromagnetic control valves.
[0048] The spraying method of the three-dimensional flux spraying system disclosed in this invention includes the following steps:
[0049] Step 1: Adjust and fix the position and cantilever length of each cantilever adjustment bolt 108 of the three-dimensional clamping mechanism according to the size and shape of the workpiece 100, and then adjust and fix the extension length and angle of each clamping adjustment bolt 111.
[0050] Step 2: At the loading station, place the lower side of the workpiece 100 onto the end of the clamping adjustment bolt 111 for support. Then, by rotating and adjusting the two left and right hand-tightening handles 142, the front and rear sides of the workpiece 100 are pressed and clamped by the ends of each clamping adjustment bolt 111. Then, start the transport trolley by turning on the start switch.
[0051] Step 3: The control unit drives the mobile drive motor 125 to slowly move the trolley carrying the workpiece 100 into the spraying chamber 201 along the track mechanism. When the card reader 120 reads the electronic tag 224 at the spraying station, the control unit stops driving the mobile drive motor 125 and sends a spraying positioning command to the main control unit 202 via wireless communication.
[0052] Step 4: After receiving the spraying positioning command, the main control unit 202 coordinates and controls the lifting drive mechanism, translation drive mechanism, rotation drive mechanism and spraying mechanism according to the preset spraying program corresponding to the workpiece 100, so that the front and rear sides of the workpiece 100 are fully sprayed, and after the spraying is completed, it sends the spraying completion command to the slave control unit via wireless communication.
[0053] Step 5: After receiving the spraying completion instruction from the control unit, drive the mobile drive motor 125 to make the transport trolley lift the workpiece 100 and continue to move slowly along the track mechanism. When the card reader 120 reads the electronic tag 224 at the unloading station, stop the drive control of the mobile drive motor 125 from the control unit and enter the unloading waiting state.
[0054] Step 6: By rotating and adjusting the two left and right hand levers 142, the workpiece 100 is released from clamping, and then the workpiece 100 is removed. After the waiting time for unloading is reached, the control unit drives the moving drive motor 125 to drive the trolley slowly along the track mechanism. When the card reader 120 reads the electronic tag 224 at the loading station, the trolley stops running and returns to step 2.

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.
