Description

Technical Field

[0001] This utility model relates to the field of laser PCB separation and tray arrangement in electronic manufacturing, specifically a dual-platform online laser PCB separation and tray arrangement integrated machine. Background Technology

[0002] The circuit board separation and tray placement process is a key link in the surface mount technology production line, which directly affects the subsequent placement operation and the final quality of the product. In this process, the circuit board is first divided into multiple small boards to facilitate subsequent processing and assembly. Then, these small boards need to be precisely trayed to ensure that various electronic components can be correctly positioned and installed in the pick-and-place machine.

[0003] Traditional board separation and traying processes often employ stand-alone operation or segmented manual intervention. The board separation process relies on mechanical cutting or laser board separation machines, and after completion, the circuit boards need to be manually transferred to the traying machine, resulting in low efficiency and easy introduction of human error. At the same time, single-station equipment operation has the problem of insufficient production continuity, long equipment idle time, and difficulty in meeting the flexible production needs of small batches and multiple batches. To address this, we propose a dual-platform online laser board separation and traying integrated machine. Utility Model Content

[0056] Working principle: The operator places the tray 9 containing the circuit boards to be separated onto the loading platform 3. At this time, the magnetic tray clamp 10 on the side of the loading platform 3 in the transfer structure starts to work. The motor 14 drives the lead screw 23 to rotate. Through the limiting cooperation between the slider 12 and the strip hole 13, the magnetic tray clamp 10 is driven to slide laterally along the L-shaped plate 7 to directly above the loading platform 3. The hydraulic cylinder 11 drives the magnetic tray clamp 10 to descend vertically. Using the magnetic attraction principle, the tray 9 is attracted and lifted to the initial position. The slider 12 slides in the opposite direction, transporting the tray 9 to above the turntable 16. The hydraulic cylinder 11 descends, causing the support frame 19 of the tray 9 to engage with the metal block 17 on the turntable 16. The magnetic block 22 is magnetically attracted and fixed to the metal block 17, completing the tray loading. After the tray 9 is positioned, the rotating structure starts. The motor 18 drives the turntable 16 to rotate, transferring the tray 9 to the work station below the laser PCB separator 1. The laser PCB separator 1, based on the preset cutting path, cuts the circuit boards in the tray 9... The circuit board is cut into independent small boards using high-precision non-contact cutting. After cutting, the turntable 16 continues to rotate, transporting the separated tray 9 to another workstation. The transfer structure on the other side is activated, and the magnetic tray clamp 10 repeats the above-mentioned lateral sliding and lifting actions to pick up the separated tray 9 from the turntable 16 and transport it to the conveyor 20 above the support 3 5. The conveyor 20 runs along the axial direction of the lead screw 23, sending the tray 9 to the designated position below the tray placement machine 2. The tray placement machine 2 locates the circuit board position through a vision recognition system. The robotic arm, in conjunction with a special clamp, accurately places the separated small boards into the tray 9 according to a preset array, ensuring the positioning accuracy during component mounting. After tray placement is completed, the conveyor 20 runs in reverse, removing the tray 9 from the equipment for manual or subsequent automated system removal. When the tray 9 on one turntable 16 is being laser separated, the transfer structure on the other side can simultaneously perform the loading action of the loading platform 3 or the unloading action of the conveyor 20, reducing equipment idle time.
