The guide rod 506 guides the locking rod 503, making the sliding of the locking rod 503 more stable.

[0028] As a technical optimization of this utility model, the lifting structure 2 includes a first lead screw 201, which is rotatably connected to the mounting frame 1. A lifting platform 202 is threadedly connected to the first lead screw 201. The lifting platform 202 is slidably connected to the guide rail on the mounting frame 1. The turnover basket 4 is installed on the lifting platform 202. A first motor 203 is installed on the mounting frame 1. The top ends of the first lead screw 201 and the first motor 203 are fixedly connected to first pulleys 204. The same first belt 205 is wound around the two first pulleys 204. Then, the first motor 203 is started, which drives the first lead screw 201 to rotate. The first lead screw 201 threadedly drives the lifting platform 202 to move up and down, so that the circuit boards in the turnover basket 4 are aligned with the push rod 705 one by one.

[0029] As a technical optimization of this utility model, a stop block 206 is fixedly connected to the lifting platform 202. The stop block 206 abuts against the side wall of the turnover basket 4.

When the turnover basket 4 abuts against the stop block 206, the turnover basket 4 no longer moves. At this time, the hydraulic rod 207 retracts and drives the limit block 208 to engage with the turnover basket 4, thereby quickly fixing the turnover basket 4 and preventing the turnover basket 4 from falling off.

[0030] As a technical optimization of this utility model, the pushing structure 7 includes a second lead screw 701, which is rotatably connected to the mounting frame 6.

Two pulleys 708 are connected by a second belt 709. When the circuit board size changes, the second motor 706 is started, which drives the second lead screw 701 to rotate. The lead screw 701 drives the slide rail 702 to move left and right, thereby quickly adjusting the position of the push rod 705 so that the push rod 705 is always aligned with the center of the circuit board in the turnover basket 4, making the push rod 705 push the circuit board more effectively. Then, the third motor 707 is started, which drives the slide block 704 to slide through the third lead screw 703. The slide block 704 drives the push rod 705 to move towards the turnover basket 4, so that the push rod 705 pushes the circuit board from the turnover basket 4 onto the conveyor belt 3. Then, the conveyor belt 3 transports the circuit board into the pick-and-place machine body 8. The push rod 705 makes the loading of the pick-and-place machine body 8 more convenient.

[0031] In use, when processing circuit boards of different sizes, the locking lever 503 on the slide 501 is pulled, causing it to disengage from the slot 504 on the turnover basket 4. Simultaneously, the locking lever 503 causes the tension spring 505 to extend, pushing the slide 501. The slide 501 then moves the locking plate 502 and causes the rollers 507 to roll within the grooves on the turnover basket 4. Through the rolling interaction between the rollers 507 and the turnover basket 4, the slide 501 moves more smoothly, requiring less effort during operation and reducing wear and tear on the slide 501. When the pallet 502 moves to the appropriate position, the locking lever 503 is released, the tension spring 505 resets, and drives the locking lever 503 to engage with the locking slot 504, thereby quickly adjusting the distance between the two pallets 502. This makes the turnover basket 4 suitable for transporting circuit boards of different sizes, making the operation more convenient and flexible. Then, the circuit boards are stacked on the two pallets 502, and the turnover basket 4 is then transported to the lifting platform 202 by a manual or automated conveying system. When the turnover basket 4 abuts against the stop block 206, the turnover basket 4 stops moving, and at this time, the hydraulic rod 207 retracts. The shrinking drive limit block 208 engages with the turnover basket 4, thereby quickly fixing the turnover basket 4 and preventing it from falling off. Next, the first motor 203 is activated, driving the first lead screw 201 to rotate. The lead screw 201 threadedly drives the lifting platform 202 to move up and down, aligning the circuit boards inside the turnover basket 4 one by one with the push rod 705. When the circuit board size changes, the second motor 706 is activated, driving the second lead screw 701 to rotate. The second lead screw 701 threadedly drives the slide rail 702 to move left and right, thereby quickly aligning the push rod 705. The position of 5 is adjusted so that the push rod 705 is always aligned with the center of the circuit board in the turnover basket 4, so that the push rod 705 can push the circuit board better. Then, the third motor 707 is started. The third motor 707 drives the slide 704 to slide through the third lead screw 703. The slide 704 drives the push rod 705 to move towards the turnover basket 4, so that the push rod 705 pushes the circuit board from the turnover basket 4 to the conveyor belt 3. Then, the circuit board is transported to the pick and place machine body 8 by the conveyor belt 3. The push rod 705 makes the loading of the pick and place machine body 8 more convenient.
