[0015] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0016] like Figure 1-6 As shown, a PCBA box sorting mechanism includes a loading frame 1, which has a box trolley feeding area 2 and a conveyor sorting area 3. The sorting mechanism also includes a Z-axis drive unit 4 fixedly connected to the loading frame 1 and located on both sides of the box trolley feeding area 2, an XY-axis drive unit 5 fixedly connected to the output end of the Z-axis drive unit 4 and located in the box trolley feeding area 2 and the conveyor sorting area 3, a rotary box picking unit 6 fixedly connected to the output end of the XY-axis drive unit 5, and a box alignment unit 7 fixedly connected to the loading frame 1 and located above the conveyor sorting area 3. The Z-axis drive unit 4 and the XY-axis drive unit 5 cooperate to drive the rotary box picking unit 6 to move along the XYZ axes. The rotary box picking unit 6 is used to push and suck up the box and adjust the length direction of the box to the Y-axis. The box alignment unit 7 is used to align the length position and width position of the box.

[0017] In actual use, the conveyor box area 3 of the box-sanding mechanism is equipped with a box conveyor. When the box trolley is pushed to the box trolley feeding area 2 for loading, the Z-axis drive unit 4 and the XY-axis drive unit 5 work together to drive the rotary box-picking unit 6 to move along the XYZ axes to above the box trolley. The rotary box-picking unit 6 pushes the box on the box trolley and adjusts the length direction of the box to the Y-axis. Then, the Z-axis drive unit 4 and the XY-axis drive unit 5 work together to transfer the box to the box alignment unit 7. The box alignment unit 7 aligns the length and width of the box. The rotary box-picking unit 6 then pushes the box on the box alignment unit 7. Finally, the Z-axis drive unit 4 and the XY-axis drive unit 5 work together to transfer the box, stacking it on the box conveyor. This helps save manpower and reduce labor intensity.

[0018] Furthermore, the Z-axis drive unit 4 includes a motor base 41 fixedly connected to the top of the loading frame 1, a servo geared motor 42 fixedly connected to the motor base 41, two first bearings 43 fixedly connected to the top sides of the loading frame 1, a drive shaft 44 with its two ends fixedly connected to the inner rings of the two first bearings 43 respectively, a first synchronous belt drive 45 connecting the servo geared motor 42 and the drive shaft 44, two second bearings 46 fixedly connected to the bottom sides of the loading frame 1, a rotating shaft 47 fixedly connected to the inner rings of the second bearings 46, a second synchronous belt drive 48 connecting the drive shaft 44 and the rotating shaft 47, a synchronous belt toothed plate 49 cooperating with the synchronous belt of the second synchronous belt drive 48, and a connecting seat 410 that cooperates with the synchronous belt toothed plate 49 to fix and clamp the synchronous belt of the second synchronous belt drive 48. The two connecting seats 410 are fixedly connected to the two sides of the XY-axis drive unit 5 respectively. Both the first synchronous belt drive 45 and the second synchronous belt drive 48 are existing technologies, consisting of two synchronous pulleys and a synchronous belt to achieve synchronous transmission, and are only used as an application example here. In use, the servo geared motor 42 drives the first synchronous belt drive 45 to rotate the drive shaft 44. The drive shaft 44 drives the synchronous belt toothed plate 49 and the connecting seat 410 to rise and fall through the second synchronous belt drive 48, thereby driving the XY axis drive unit 5 to rise and fall.

[0019] Furthermore, the Z-axis drive unit 4 also includes at least two Z-axis slide rails 411 fixedly connected to both sides of the loading frame 1, and a first slider 412 slidably engaged with the Z-axis slide rails 411. The first sliders 412 on both sides of the loading frame 1 are fixedly connected to both sides of the XY-axis drive unit 5 to improve the stability of the XY-axis drive unit 5 during the lifting process. In addition, in this embodiment, the XY-axis drive unit 5 is prior art, which consists of two Y-axis linear modules and one X-axis linear module. The two Y-axis linear modules are fixedly connected to two connecting seats 410 one-to-one. The two ends of the X-axis linear module are fixedly connected to the output ends of the two Y-axis linear modules.

The suction surface of the vacuum suction cup 64 is located on the side of the vacuum suction cup 64 away from the wide-type finger cylinder 63. The wide-type finger cylinder 63 and the two vacuum suction cups 64 cooperate to press and adsorb the two inner sides of the box in the width direction. In use, the wide-type finger cylinder 63 drives the two vacuum suction cups 64 to press against the two inner sides of the box in the width direction, and the vacuum suction cups 64 vacuum and adsorb the two inner sides of the box in the width direction. After the box is lifted by the cooperation of the Z-axis drive unit 4 and the XY-axis drive unit 5, the rotary cylinder 62 is used to adjust the length direction of the box to the Y-axis.

[0021] Furthermore, the bin alignment unit 7 includes a hanging beam 71 fixedly connected to the loading frame 1 and located above the conveyor box loading area 3, a fixed base 72 fixedly connected to the hanging beam 71, a Y-axis drive assembly 73 fixedly connected to the fixed base 72, an alignment base plate 74 fixedly connected to the output end of the Y-axis drive assembly 73, a first guide rod cylinder 75 fixedly connected to the end of the alignment base plate 74 away from the bin trolley feeding area 2, and an alignment push plate 76 fixedly connected to the output end of the first guide rod cylinder 75. The first guide rod cylinder 75 and the alignment push plate 76 cooperate to push and align the length position of the bin. In this embodiment, when the bin needs to be transferred to the bin alignment unit 7, the Y-axis drive assembly 73 drives the alignment base plate 74 closer to the end of the XY axis drive unit 5. After the bin is placed into the bin alignment unit 7, the first guide rod cylinder 75 drives the alignment push plate 76 to push and align the length position of the bin. When the hopper needs to be transferred to the hopper conveyor, after the top suction hopper of the rotating hopper unit 6 is rotated, the Y-axis drive assembly 73 drives the alignment plate 74 away from the end of the XY axis drive unit 5 to make way for the hopper to move down.

[0022] Furthermore, two symmetrically distributed guide alignment strips 8 are fixedly connected to both sides of the alignment base plate 74. The two guide alignment strips 8 are used to align the width position of the material box.

[0023] Furthermore, the Y-axis drive assembly 73 includes a second guide rod cylinder 731 fixedly connected to the fixed base 72, a second slider 732 fixedly connected to both sides of the fixed base 72, and a Y-axis slide rail 733 fixedly connected to both sides of the bottom surface of the alignment base plate 74.
