[0096] The utility model embodiment further provides an automatic bending and dipping tin method based on the above-mentioned flux dipping rack based on electromagnetic coil pins and automatic dipping tin equipment, specifically comprising the following steps:

[0097] The to-be-operated electromagnetic coil is installed into the feeding conveyor belt assembly 21 in the feeding carrying structure 2 in the outward direction of the pin, the start button is pressed, the feeding conveyor belt assembly 21 operates, after the feeding conveyor belt assembly 21 is detected to exist the electromagnetic coil by the material laser detection assembly 23, the feeding transfer assembly 22 extracts the electromagnetic coil and carries to the positioning loading seat body 32 of the loading turntable structure 3; then the feeding conveyor belt assembly 21 runs again to convey the electromagnetic coil to the feeding waiting position, and the feeding conveyor belt assembly 21 stops operating until the material laser detection assembly 23 cannot detect the coil corresponding to the feeding conveyor belt assembly 21, and the feeding conveyor belt assembly 21 waits to place the electromagnetic coil again; at this time, the plurality of groups of electromagnetic coils are correspondingly arranged in the plurality of groups of positioning loading seat bodies 32, and the pins of the plurality of groups of electromagnetic coils all keep outward;

[0098] The plurality of groups of electromagnetic coil pins are sequentially indexed to the pin bending structure 4 to carry out the bending process, after the electromagnetic coil to be bent is rotated to the position by the driven turntable assembly 31, the coil body is first pressed and fixed by the coil pressing assembly 42 in the pin bending structure 4, then the pin bottom support cylinder 431 in the pin bottom support assembly 43 drives the bottom support pad 433 to go up, and the bottom support pad 433 is contacted and abutted upward to the coil pin, and then the bending and stamping cylinder 441 in the bending and stamping assembly 44 drives the bending and stamping head 443 to go down, the coil pin is contacted and stamped by the stamping head 443, and the coil pin is bent downward to form;

[0099] After the electromagnetic coil pin is bent and formed, under the control of the electric control structure 9, the components of the pin bending structure 4 are sequentially withdrawn, and the electromagnetic coil remaining in the loading turntable structure 3 completes the pin bending process;

[0100] The plurality of groups of electromagnetic coil pins completing the bending process are sequentially indexed to the flux dipping structure 5 to carry out the flux dipping process, after the electromagnetic coil to be dipped is rotated to the position by the driven turntable assembly 31, the flux dipping transfer assembly 51 in the flux dipping structure 5 drives the flux dipping pneumatic clamp 514 downward by the first flux dipping lifting cylinder 512, the electromagnetic coil completing the bending process on the work position is grabbed by the flux dipping pneumatic clamp 514, and the electromagnetic coil is lifted upward by the first flux dipping lifting cylinder 512; then the flux dipping transfer assembly 51 further drives the flux dipping pneumatic clamp 514 and the electromagnetic coil grabbed thereby to move to the position above the flux dipping agent lifting assembly 52 by the flux dipping translation cylinder 511; then the flux dipping transfer assembly 51 rotates the flux dipping pneumatic clamp 514 by the flux dipping translation motor 513, the electromagnetic coil pin dipping position is downward, and the electromagnetic coil pin dipping position is positioned;

[0101] Further driven by the second flux lifting cylinder 522 in the flux lifting assembly 52, the flux lifting tank frame 523 and the flux therein are lifted to the position of the pin of the electromagnetic coil, until the pin of the electromagnetic coil that needs to be immersed in tin dips into the flux in the flux lifting tank frame 523 at a specific height;

[0102] Continuing to control the second flux lifting cylinder 522 to drive the flux lifting tank frame 523 to descend to the original position, and the flux transfer position assembly 51 drives the flux pneumatic clamping jaw 514 to transfer and shift, respectively, and then the electromagnetic coil is put back to the loading turntable structure 3, so as to complete the flux dipping process of the pin of the electromagnetic coil;

[0103] In an optional embodiment, in the static state, the liquid level of the flux storage tank 521 is higher than the upper end of the containing opening of the flux lifting tank frame 523, so that the flux in the flux lifting tank frame 523 is full tank state every time the flux lifting tank frame 523 is lifted, and the height consistency of the electromagnetic coil pin dipping flux is ensured;

[0104] In another optional embodiment, the flux lifting assembly 52 has a liquid level detection function. When the liquid level in the flux storage tank 521 is lower than the set value monitored by the liquid level detection assembly 524, the system alarms and stops working. After adding flux, the system can work again. Specifically, when the flux is consumed and the liquid level in the flux storage tank 521 is lowered, the built-in photoelectric switch of the liquid level detection assembly 524 cannot sense the liquid level, so the indicator light is on, and then an instruction signal is output. After the system receives the instruction signal, it stops working. The external touch screen prompts that the liquid level of the flux is low and needs to be replenished. After the photoelectric switch recognizes that the replenishment is completed, the indicator light is turned off, the output signal disappears, and the system is reset to resume work;

Then the tin immersion transfer position assembly 61 drives the tin immersion pneumatic clamping jaw 614 to rotate by the tin immersion transfer position motor 613, so that the electromagnetic coil pin immersion part is downward, and the electromagnetic coil pin immersion positioning is completed;

[0106] Meanwhile, the tin liquid scraping assembly 62 corresponding to the molten tin storage assembly 63 is used to remove the floating dregs on the surface of the molten tin, specifically: the scraping translation cylinder 621 in the tin liquid scraping assembly 62 is controlled to push the extension scraping plate 624 to one end of the molten tin storage assembly 63, then the extension scraping plate 624 is lowered to the surface of the tin liquid by the scraping lifting cylinder 623 in the tin liquid scraping assembly 62, then the extension scraping plate 624 is recovered to the other end of the molten tin storage assembly 63 by controlling the scraping translation cylinder 621, so as to clean the floating dregs on the surface of the tin liquid, then the extension scraping plate 624 is lifted away from the surface of the tin liquid by the scraping lifting cylinder 623, so as to complete the surface cleaning once;

[0107] Further, the tin immersion lifting cylinder 612 is controlled by the electric control structure 9 to drive the tin immersion pneumatic clamping jaw 614 and the electromagnetic coil pin end grasped thereby to descend, the electromagnetic coil pin end descending has a descending height automatic adjustment compensation function, that is, when the tin liquid level height slowly decreases due to the consumption of the tin, the tin liquid level height is fed back to the electric control structure 9 in real time by the laser ranging assembly 615, the electric control structure 9 controls the descending height of the tin immersion lifting cylinder 612 after calculation, so as to ensure that the electromagnetic coil pin is immersed in the tin liquid to a consistent depth, thereby ensuring the consistency of the tin immersion quality, so as to insert the electromagnetic coil pin end into the internal tin liquid surface of the molten tin storage assembly 63, so that the electromagnetic coil pin completes the tin immersion process to a predetermined height;

[0108] The laser ranging assembly 615 is provided with a standard liquid level height value and a maximum liquid level decrease value, when it is monitored that the liquid level decrease exceeds the set maximum value, the whole machine system alarms and stops working until the specific tin liquid is refilled, and then the tin immersion work can be unlocked again;

[0109] The electromagnetic coil pins after the tin immersion process are sequentially indexed to the impedance detection structure 7 to perform the impedance detection process, after the electromagnetic coil to be detected is rotated to the position by the driven turntable assembly 31, the test probe 73 is first driven by the horizontal telescopic cylinder 71 in the impedance detection structure 7 to extend and contact the electromagnetic coil pin, the coil impedance is detected by the upper and lower limit alarm resistance meter 72 of the electric control structure 9, when the detected impedance is within the required range, the upper and lower limit alarm resistance meter 72 does not alarm, the system does not receive the alarm signal within the specified time, that is, it is defaulted that the coil impedance at this position is qualified and is recorded, when the impedance is not within the required range, the upper and lower limit alarm resistance meter 72 will alarm, the system receives the unqualified signal and records the unqualified record;

[0110] The unqualified products in the detected electromagnetic coil are carried into the corresponding unqualified collector by the unloading transfer assembly 81 according to the system determination result, and the qualified products are carried to the unloading conveyor belt assembly 82, and then the tin immersion appearance inspection is performed after the conveying and the products are placed into the turntable.
