Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, specifically a calibration device for laser marking of FPC. Background Technology

[0002] FPC is short for Flexible Printed Circuit Board, a type of printed circuit with high reliability and excellent flexibility. FPC processing requires laser marking. The motion system controls the laser beam to move along a predetermined path to form the required mark on the FPC. Before laser marking, in order to avoid the marking position from being off, the position of the laser marking needs to be calibrated by a calibration device.

[0003] Chinese patent publication number CN222113922U discloses a calibration device for laser marking. By manually rotating a bidirectional lead screw, two movable blocks are controlled to move two infrared emitters synchronously in a direction of distance until the distance between the two infrared emitters is consistent with the width of the area to be marked on the product. Then, the two infrared emitters are turned on to emit calibration red dots onto the product surface. The product can be quickly calibrated and corrected by the two calibration red dots, so that the area to be marked on the product is directly below the laser marking machine and between the two calibration red dots. The calibration is quick and easy to operate.

[0004] However, during calibration and correction, the device can only correct the distance between the two points of the infrared emitter. When the product angle deviates to a certain extent, the coding areas on both sides of the product can still exist between the two calibration red points, making it difficult to accurately calibrate and correct the product in parallel, thus affecting the subsequent coding quality.

[0019] By adjusting the second threaded rod, the moving bar is moved, which in turn moves the push rod.

This adjusts the irradiation angle of the two infrared emitters and the distance between the two points on the product illuminated by the two infrared emitters. The device can be adjusted and calibrated according to different sized marking areas, improving its flexibility. Attached Figure Description

[0034] In this embodiment: the concave frame 202 is limited by the cross groove 204, and the concave frame 202 can slide on the inner wall of the cross groove 204.

[0035] Specifically, such as Figures 1-3 As shown, two limiting blocks 203 are fixedly installed on the two sides of the concave frame 202, and the sides of the multiple limiting blocks 203 are slidably connected to the inner walls of the two cross grooves 204.

[0036] In this embodiment: the limiting block 203 is limited by the set cross groove 204, and the limiting block 203 limits the concave frame 202, so that the movement of the concave frame 202 is more stable.

Rotating plates 304 are fixedly installed on the sides of the two fixing blocks 302 respectively. Limiting sleeves 305 are fixedly installed on the sides of the two rotating plates 304 respectively.

[0041] In this embodiment: the rotating plate 304 drives the fixed block 302 to rotate, and the fixed block 302 drives the infrared emitter 207 to rotate at a certain angle.

[0042] Specifically, such as Figures 1-5 As shown, the inner walls of the two grooves 301 are provided with arc-shaped grooves 306. The outer wall of the limiting sleeve 305 is slidably connected to the inner wall of the arc-shaped groove 306.

The two ends of the arc-shaped rod 307 are fixedly connected to the inner walls on both sides of the arc-shaped groove 306. An elastic element 308 is slidably sleeved on the outer wall of the arc-shaped rod 307. The two ends of the elastic element 308 are fixedly connected to the bottom surface of the limiting sleeve 305 and the lower inner wall of the arc-shaped groove 306, respectively.

[0043] In this embodiment: the arc-shaped rod 307 limits the movement of the limiting sleeve 305, making the rotation of the limiting sleeve 305 more stable, and the elastic element 308 applies elastic force to the limiting sleeve 305.

[0044] Specifically, such as Figures 1-5As shown, the top surfaces of the two rotating plates 304 are respectively provided with push grooves 309, the top surface of the concave frame 202 is fixedly installed with a support frame 310, the inner wall of the support frame 310 is slidably installed with a moving strip 311, the bottom surfaces of the two ends of the moving strip 311 are respectively fixedly installed with push rods 315, the lower ends of the two push rods 315 slide through the top surface of the concave frame 202 and extend into the inside of the groove 301, and the lower ends of the two push rods 315 are slidably connected to the inner walls of the two push grooves 309 respectively.

[0045] In this embodiment: the push rod 315 is moved by the movable bar 311, and the angle of the infrared emitter 207 is adjusted under the combined action of the push rod 315 and the elastic element 308.

[0046] Specifically, such as Figures 1-5 As shown, two limiting rods 312 are slidably installed through the top surface of the moving bar 311.

[0047] In this embodiment: the threaded rod 313 can drive the moving bar 311 to move, and the limiting rod 312 limits the moving bar 311, making the movement of the moving bar 311 more stable.

[0048] Specifically, this solution involves adjusting the threaded rod 313, which moves the moving bar 311. The moving bar 311 then moves the push rod 315. Simultaneously, under the action of the elastic element 308, the angle of the rotating plate 304 is adjusted, causing the fixed block 302 and the infrared emitter 207 to rotate. This adjusts the irradiation angle of the two infrared emitters 207 and the distance between the two points on the product illuminated by the two infrared emitters 207. This adjustment and calibration can be performed according to different coding areas, improving the flexibility of the device. By turning on the motor 206, the motor 206 rotates the threaded rod 205, which moves the concave frame 202. The concave frame 202 then moves the two infrared emitters 207 below. By moving the irradiation point of the infrared emitter 207 in a straight line with the edge of the product, and comparing the distance between the irradiation point and the edge of the product, the product is calibrated, ensuring that the product is in the coding position and the angle is not easily offset, thus improving the coding quality.
