Referring to fig. 3 to 4, the bearing assembly includes:
a transfer mounting plate 761 slidably connected with the feeder frame 721;
a carrying mounting plate 763 installed on the transfer mounting plate 761 and having a lifting passage 7631 formed therein to extend in a vertical direction;
a carrier lifter plate 766, said carrier lifter plate 766 being at least partially received in said lifter channel 7631 and being slidably connected to said carrier mounting plate 763; and

Further, a suction stopper 7641b arranged around the vacuum suction hole 7641c is formed on the top surface of the workpiece stage 7641. Therefore, the workpiece can be limited by the positioning of the absorption limiting column 7641b after being absorbed by the vacuum absorption hole 7641c, and the absorption precision and stability of the workpiece by the vacuum absorption hole 7641c are improved.
Further, a suction passage 7644 extending to the vacuum suction hole 7641c is formed inside the bearing lift-up head 764.
Further, the top surface of the workpiece carrier 7641 is formed with at least one positioning accommodating groove 7641a located beside the vacuum suction hole 7641 c.

In the in-service use in-process, the supporting lifter plate 766 is replaced through the dismounting limiting wings 7632, so that the supporting jacking heads 764 can be replaced correspondingly according to different workpiece sizes or characteristics, and the applicability and the practicability are greatly improved.
Referring to fig. 3 and 4, the blanking support mechanism 76 further includes:
a transfer mounting seat 7212 fixedly arranged on the feeding frame 721, and a material cutting station 7212a and a transfer station 7212b are sequentially arranged on the transfer mounting seat along a linear direction;
a transfer mounting plate 761 slidably coupled to the transfer mount 7212; and

the carrier mounting plate 763 is fixedly mounted on the transfer mounting plate 761, and the carrier mounting plate 763 is driven by the transfer driver 762 to and fro switch between the blanking station 7212a and the transfer station 7212b along with the transfer mounting plate 761. In actual use, the load-bearing jacking head 764 is driven by the transfer drive 762 to the transfer station 7212b after cutting the workpiece from the web at the cutting station 7212a, and waits for the cut workpiece to be handled by a robot or manually to the processing line for assembly or rework.
In the embodiment shown in fig. 2, it can be seen that the end of the tape guide 722 is integrally formed with a position-limiting block plate 7222 opposite to the bearing position-limiting table 7642, and when the bearing jacking head 764 is located at the blanking station 7212a, the bearing position-limiting table 7642 is located right below the position-limiting block plate 7222, so that the position-limiting block plate 7222 can cooperate with the bearing buffer columns 7643 on the bearing position-limiting table 7642 to limit the position of the bearing jacking head 764 in the vertical direction.
In the embodiment shown in fig. 2, it can be seen that a waste material guide plate 75 is disposed downstream of the tape guide plate 722, a waste material pressing plate 752 covers the waste material guide plate 75, a waste material guide gap is formed between the waste material pressing plate 752 and the waste material guide plate 75, and waste materials generated after the workpiece is cut by the tape are guided out and collected through the waste material guide gap.
Referring to fig. 7 to 9, the die cutting mechanism 73 includes:
a positioning base 732 fixed to the feeder frame 721, in which a blanking passage 7321 extending in a vertical direction is formed;
a punching and cutting plate 734, the punching and cutting plate 734 being at least partially received in the punching channel 7321 and being slidably connected to the positioning base 732, a pre-pressing channel 7341 extending in a vertical direction being formed in the punching and cutting plate 734, the pre-pressing channel 7341 being opposite to the punching platform 739;
a blanking pre-press plate 736, the blanking pre-press plate 736 being at least partially received in the pre-press channel 7341 and being in sliding connection with the blanking plate 734; and
a blanking driver 733, a power output end of which is in transmission connection with the blanking plate 734, the blanking plate 734 being driven by the blanking driver 733 to reciprocate along the blanking channel 7321;
in the process of descending or ascending along with the blanking plate 734, the blanking prepressing plate 736 can ascend or descend along the vertical direction relative to the blanking plate 734 when contacting with or gradually separating from the blanking supporting platform 739 to switch between a prepressing state and a natural state. By adopting the blanking and cutting mechanism 73 with the characteristics, the impact force before the contact between the blanking and cutting material plate and the blanking bearing platform can be buffered by slidably connecting the blanking prepressing plate in the blanking and cutting material plate, and meanwhile, the blanking prepressing plate can also perform prepressing positioning on the material belt, so that the cutting precision and the cutting quality of a workpiece are improved.
As can be seen from the embodiment shown in fig. 11 and 12, a buffering return member 7364 is elastically connected between the blanking prepressing plate 736 and the blanking blade 734, and the buffering return member 7364 acts on the blanking prepressing plate 736 such that the blanking prepressing plate 736 can be lowered in a vertical direction relative to the blanking blade 734 to return from the prepressed state to the natural state while gradually separating from the blanking platform 739 while ascending along with the blanking blade 734.

When a workpiece is blanked, the pre-pressing head 7362 protrudes from the bottom surface of the blanking head 735, so that the pre-pressing head 7362 contacts with the material belt on the blanking supporting platform 739 first, and the material belt is pre-pressed and compacted, thereby preventing the blanking precision from being reduced due to the movement of the material belt in the blanking process.
As can be seen in the embodiment shown in fig. 11, the bottom surface of each of the pre-pressing heads 7362 is formed with a corresponding one of the pre-pressing guide posts 7363 protruding downward.

The arrangement of the debugging opening is convenient for debugging and the blanking and blanking plate 734 which is adapted to the workpiece or the material belt with different sizes and shapes can be replaced, thus greatly improving the applicability.

Two opposite buffering limit stages are formed at the top of the T-shaped prepressing channel 7341, and each prepressing lug 7361 is aligned with a corresponding buffering limit stage when the blanking prepressing plate 736 is assembled into the prepressing channel 7341.
Further, a driver mounting frame 738 is fixedly connected to the top of the positioning base 732, the blanking driver 733 is mounted on the driver mounting frame 738, and a power output end of the blanking driver 733 penetrates through the driver mounting frame 738 and is in transmission connection with the blanking plate 734.
