[0043] When the size of the circuit board changes, the distance between the second conveying side plate 22 and the first conveying side plate 21 can be adjusted by adjusting the width of the driving motor 32 , thereby adjusting the distance between the two conveying belts 23 .

[0044] The conveying mechanism of this embodiment has good compatibility and can convey circuit boards and fixtures of various sizes.

[0045] like Figure 5 As shown, the in-place blocking device 4 may include a blocking lifting cylinder 41 and a blocking block 42 for blocking the product fixture. The blocking lifting cylinder 41 is connected to the blocking block 42 and can drive it to move up and down.

[0046] When the circuit board is delivered to the labeling station, the blocking lifting cylinder 41 can drive the blocking block 42 to move upward to block the product jig. When the labeling is completed, the blocking lifting cylinder 41 can drive the blocking block 42 to move downward, so that the circuit board and the product jig can flow out through the double belt conveyor 2.

[0047] like Figure 6 As shown, the side pressure device 5 may include a side pressure mounting seat 51, a side pressure driving cylinder 52 and a side pressure block 53 for pressing the product fixture. The side pressure driving cylinder 52 is installed on the outer side surface of the second conveying side plate 22 through the side pressure mounting seat 51. The second conveying side plate 22 is provided with a pressure block through hole for the side pressure block 53 to pass through. The side pressure driving cylinder 52 can drive the side pressure block 53 to extend into the inner side of the second conveying side plate 22.

[0048] When the circuit board is transported to the labeling station, the side pressure driving cylinder 52 can drive the side pressure block 53 to press against the product fixture to perform side pressure positioning on the product fixture.

[0050] When the circuit board is transported to the labeling station, the lifting and leveling driving cylinder 61 can drive the lifting cone column 65 to move upward, and the lifting cone column 65 can lift the product fixture and close to the bottom of the lifting limiter 10.

[0051] Since the double-belt conveyor device 2 uses a conveyor belt to convey the product jig, the conveyor belt is flexible and will deform, which will cause the position of the product jig to be skewed. After adding the jacking and leveling device 6 and the jacking limit member 10, with the cooperation of the jacking cone column 65 and the jacking limit member 10, the product jig can maintain good flatness (in a horizontal state), which is conducive to labeling.

[0052] like Figures 8 to 11As shown, the label feeding device 7 may include a label feeding side plate 71, a label unwinding plate 72, an unwinding guide roller 73, a peeling knife 74, a peeling knife lateral movement driving cylinder 75, a waste paper guide roller 76, a waste paper traction roller 77, a waste paper pressing roller 78, a waste paper winding plate 79 and a winding driving motor 710. The label unwinding plate 72 is installed above the rear end of the label feeding side plate 71. The label unwinding plate 72 is used to store the label tape, and the waste paper winding plate 79 is used to store the label tape. The waste paper reel 79 is installed below the rear end of the stripping label feeding side plate 71, and is used to reel in the waste paper after stripping the label. The unwinding guide roller 73 is located between the label unwinding reel 72 and the waste paper reel 79. The stripping knife 74 is installed at the front end of the stripping label feeding side plate 71 and is slidably connected to the stripping label feeding side plate 71 through a linear guide rail 718. The stripping knife lateral movement driving cylinder 75 is installed on the stripping label feeding side plate 71 and is transmission-connected to the stripping knife 74.

The anti-static mounting column 711 and the label pressing cylinder 715 are both located above the supporting platform. The anti-static plate 713 is mounted on the anti-static mounting column 711 through the mounting tube 712. The mounting tube 712 is fixed to the anti-static mounting column 711 through the locking screw 714. The label pressing cylinder 715 is connected to the label pressing block 716 and can drive it to move up and down.

[0054] The position of the anti-static plate 713 can be easily adjusted by loosening the locking screw 714. The anti-static plate 713 can remove static electricity on the label, thereby preventing the static electricity on the label from affecting the electronic components on the circuit board.

[0055] During operation, the label material tape can pass through the label unwinding disk 72, the unwinding guide roller 73, the anti-static plate 713, the peeling knife 74, the waste paper guide roller 76, the waste paper traction roller 77 and the waste paper winding disk 79 in sequence.

[0058] In this embodiment, the heater 82 can transfer heat to the suction cup 84 through the connecting seat 83, and then transfer heat to the label, so that the heating helps the label to be attached to the circuit board.

[0059] When the label stripping and feeding device 7 strips the label, the XYZ axis moving module 81 can drive the suction cup 84 to absorb the label and move the label to a designated position on the circuit board.
