This inductor dispensing device can first dispense adhesive into the mold cavity, then implant the semi-finished wire-wound inductor, and then perform secondary dispensing and replenishing adhesive to correct the dispensing. The secondary dispensing avoids the impact of pressing on the adhesive on the inductor, thus solving the problem of poor adhesive coverage caused by insufficient flow to uncovered areas during rapid entry into the baking equipment. Replenishing adhesive after re-inspection ensures that the adhesive covers the winding portion of the product, significantly improving the product's pass rate, avoiding excessive scrap rates due to inappropriate dispensing, and reducing production costs.

After secondary glue application, ensure that the glue covers the product surface, except for the electrode area. The completeness of the glue application on the inductor coil is determined by comparing the results using an image recognition algorithm. Step 4: Obtain images of the secondary adhesive dispensing of the inductor coil; Step 5: Determine whether the inductor coil dispensing in the dispensing image is complete. If it is complete, the inductor coil dispensing is qualified. If the dispensing is unqualified, proceed to Step 6 to re-apply the adhesive. The determination of whether the inductor coil dispensing is complete is obtained by comparing images using an image recognition algorithm. Step 6: Determine the glue application location of the inductor coil, stop the inductor movement for a set time, and control the electric dispensing device to move towards the glue application location in the inductor movement direction and apply glue.
