When adsorbing irregularly shaped objects, such as L-shaped or ring-shaped objects, air leakage in the uncovered areas leads to insufficient adsorption force, making the objects easy to shift or fall off, and even causing edge warping or loose center after labeling, affecting the labeling effect.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figures 1-5 As shown, this embodiment provides a fully automatic optical labeling device for circuit boards, including a mounting platform 100. Two mounting blocks 101 are respectively installed at the upper and lower ends of the mounting platform 100. Multiple hollow motors 102 are installed on the mounting block 101 at the lower end, and multiple piston cylinders 103 are installed on the mounting block 101 at the upper end. Multiple labeling components 200 are provided at the front end of the mounting platform 100. The labeling assembly 200 includes a straw 201, the outer peripheral wall of the straw 201 is slidably connected to the inner wall of the hollow shaft of the hollow motor 102, a limiting block 202 is fixedly provided on the outer wall of the straw 201, the limiting block 202 is slidably connected to the hollow shaft of the hollow motor 102, a connector end 203 is connected to the upper end of the straw 201, a labeling head 204 is connected to the lower end of the straw 201, a cross block 205 is fixedly provided inside the straw 201, and a suction adjustment assembly 300 is installed on the upper end of the straw 201. The suction adjustment component 300 includes a sealing block 301, a movable block 302 is slidably connected inside the sealing block 301, and a slot 303 is provided on the cross block 205, with the movable block 302 and the slot 303 being inserted and engaged.

[0022] A limiting ring 206 is fixedly provided at the upper end of the straw 201. A push block 207 is sleeved on the outer peripheral wall of the limiting ring 206. The push block 207 is rotatably connected to the outer peripheral wall of the straw 201. The bottom surface of the piston rod of the piston cylinder 103 is fixedly connected to the top surface of the push block 207. When the piston rod of the piston cylinder 103 pushes the push block 207 to move the straw 201, the push block 207 can rotate relative to the straw 201, which reduces the frictional resistance between the two and ensures that the straw 201 rises and falls smoothly.

[0023] Multiple sealing blocks 301 are provided, and each sealing block 301 is fixedly connected to the outer peripheral wall of the suction tube 201. The sealing blocks 301 are connected to the slots 303. A first electric push rod 304 is installed on the top surface of the sealing block 301. A connecting block 305 is fixedly installed on the top surface of the movable block 302. The piston rod of the first electric push rod 304 is fixedly connected to the connecting block 305. The multiple sealing blocks 301 are fixedly connected to the outer peripheral wall of the suction tube 201 and are all connected to the slots 303 on the cross block 205. With the cooperation of the first electric push rod 304 on the top surface of the sealing block 301, the vacuum degree of multiple independent air chambers can be adjusted in parallel.

[0024] The mounting head 204 is equipped with a nozzle holder 214, and a flip plate 209 is rotatably connected to the nozzle holder 214 via a rotating shaft 208. A laser profilometer 210 is mounted on the flip plate 209, and a cross block 205 extends through the nozzle holder 214 into the inside of the nozzle. The laser profilometer 210 on the flip plate 209 scans the outline of the circuit board surface and the label position before labeling.

[0025] A hinge 211 is fixed on the outer peripheral wall of the suction nozzle seat 214. A second electric push rod 212 is rotatably connected to the pin of the hinge 211. A round shaft 213 is rotatably connected to the piston rod of the second electric push rod 212. The round shaft 213 is fixedly connected to the upper end of the flip plate 209. The second electric push rod 212 drives the flip plate 209 to rotate through the hinge 211 and the round shaft 213, thereby adjusting the scanning angle of the laser profilometer 210 and realizing multi-angle data acquisition.

[0026] The straw 201, push block 207 and movable block 302 are respectively separated from the mounting platform 100; this avoids interference when the components move and ensures that the device maintains smooth and coordinated operation during operation.

[0027] Working principle: The labeling platform 100 fixes the hollow motor 102 and the piston cylinder 103 respectively through the mounting blocks 101 at the upper and lower ends, providing motion and power support for the labeling assembly 200. The suction tube 201 of the labeling assembly 200 and the hollow shaft of the hollow motor 102 are slidably connected through the limiting block 202, so that the suction tube 201 can move up and down within the hollow shaft to adjust the position and angle of the labeling head 204. The cross block 205 inside the straw 201 divides the inside of the straw 201 into multiple independent air chambers. Each air chamber corresponds to a different area of ​​the labeling head 204. When labeling a circuit board is required, an external air source provides negative pressure airflow to the straw 201 through the connector end 203. The movable block 302 moves linearly within the sealing block 301 and engages with the slot 303. By controlling the depth and position of the movable block 302 inserted into the slot 303, the vacuum channel corresponding to each air chamber can be selectively opened or closed, thereby independently adjusting the vacuum level of each air chamber. This facilitates the control of the suction force in the corresponding area, avoids insufficient adsorption force caused by air leakage in uncovered areas, prevents objects from shifting or falling off, and improves the stability of the labeling process. When picking up L-shaped labels, the control system can activate the suction of the air chamber corresponding to the L-shaped outline area only, and close the air chamber of the uncovered area to avoid air leakage; the piston cylinder 103 pushes the push block 207 through the piston rod, which drives the suction tube 201 to move up and down, realizing the bonding and separation action between the mounting head 204 and the circuit board, and completing the labeling work; by adjusting the vacuum degree of different air chambers, suction is applied to the edge of the label and the suction in the center area is reduced, so that the label is flatly adsorbed, improving the labeling effect and avoiding the impact of poor labeling on product quality; The limiting ring 206 fixed at the upper end of the straw 201 is rotatably connected to the push block 207, so that when the piston rod of the piston cylinder 103 pushes the push block 207 to move the straw 201, the push block 207 can rotate relative to the straw 201, reducing the frictional resistance between the two and ensuring that the straw 201 rises and falls smoothly, avoiding the deviation of the labeling head 204 due to jamming; multiple sealing blocks 301 are fixedly connected to the outer peripheral wall of the straw 201, and all are connected to the slots 303 on the cross block 205. With the cooperation of the first electric push rod 304 on the top surface of the sealing block 301, the vacuum degree of multiple independent air chambers can be adjusted in parallel; when adsorbing large-area labels, the corresponding first electric push rod 304 controls the movable block 302 to adjust the suction force of each air chamber according to the adsorption needs of different areas of the label, thereby improving the labeling efficiency; The nozzle seat 214 on the placement head 204 is rotatably connected to the flip plate 209 via the rotating shaft 208. The laser profilometer 210 on the flip plate 209 scans the surface morphology and pre-placement coordinates of the circuit board before labeling. The second electric push rod 212 drives the flip plate 209 to rotate via the hinge seat 211 and the round shaft 213, adjusting the scanning angle of the laser profilometer 210 to achieve multi-angle data acquisition. The cross block 205 extends through the nozzle seat 214 into the nozzle, ensuring that each air chamber corresponds to the nozzle and that the suction force is accurately applied to the target area. The gaps reserved between the suction tube 201, push block 207 and movable block 302 and the mounting platform 100 avoid interference when the components move, ensuring that the device maintains smooth and coordinated operation during operation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
