When working, the suction head 5 first absorbs the light bar 1 located on the adsorption platform 701, and then through the linkage of the sixth linear module 801, the seventh linear module 802 and the eighth linear module 803, the suction head 5 and The light strip 1 clamped by the suction head 5 moves from the shaping station to the preset blanking position, and the driving motor 804 is used to adjust the posture of the suction head 5, so that the light strip 1 can be rotated to the actual required posture and discharged to the Default position. In this embodiment, the sixth linear module 801 is preferably a screw module, and the seventh linear module 802 and the eighth linear module 803 are preferably cylinder modules.

Please refer to Figure 14 and Figure 15 together. The distance between the plurality of light bars 1 shown in Figure 15 is actually very small. When one of the light bars 1 is taken out, the adjacent light bars 1 The strip 1 is easily separated from the carrier sheet 2 under the pulling force, so as to ensure the high reliability of removing the light strip 1 . The light bar automatic feeder also includes a pressing mechanism 200, which is connected to the frame 10 and arranged in the waiting area (that is, the farthest place where the rewinding and unwinding mechanism 50 drives the material belt 4 to be released), and the waiting area is set There are a plurality of light bars 1, and the plurality of light bars 1 located in the waiting area include a plurality of light bars 11 to be clamped and a plurality of light bars 12 to be released arranged in sequence along the opposite direction of the discharging direction of the unwinding mechanism 50, The material pressing mechanism 200 is used for applying pressure to at least one light bar 12 to be released at the material waiting area. In this embodiment, the pressing mechanism 200 specifically includes a connected pressing cylinder 201 and a pressing block 202. The pressing cylinder 201 is fixed on the frame 10, and the pressing cylinder 201 is used to drive the pressing block 202 to rise or fall. Before the light bar 11 to be clamped needs to be taken away by the claw cylinder 606 on the material shifting mechanism 60, the pressing cylinder 201 needs to drive the pressing block 202 down, and make the pressing block 202 press the multiple lamps to be released behind. Bar 12; when the light bar 11 to be clamped is removed, the pressing cylinder 201 needs to drive the pressing block 202 to rise, and then the rewinding and unwinding mechanism 50 drives the material belt 4 forward for a short distance, so that the original light bar to be released 12 becomes the light bar 11 to be clamped. By setting the pressing mechanism 200, when the clamping claw cylinder 606 on the material shifting mechanism 60 clamps the light bar 11 to be clamped, the light bar 12 to be released at the rear will not be pulled by the light bar 11 to be clamped when it leaves force to separate from the carrier sheet 2, thereby ensuring that the light bars 1 can be reliably clamped by the jaw cylinder 606 on the material transfer mechanism 60 one by one.

To sum up, the automatic feeding method of the technical solution can efficiently supply the light bar 1 to the required position, thereby greatly improving the production efficiency of products containing the light bar.
