Examples
Referring to fig. 1 to 6, the present embodiment provides a mechanical arm claw 1 for transferring a metal copper-based lead frame 2, which is used for transferring the metal copper-based lead frame 2 and mainly includes: the support plate 11, the clamping plate group 12, the lifting rod 13, the transmission rod 14, the driving source and the connecting mechanism 16.
The metal copper-based lead frame 2 has a rectangular connecting hole 21 at the edge thereof.
The stay 11 may be connected to a robot arm for driving the robot arm nail 1.
At least one of the clamping plate sets 12 is arranged, the clamping plate set 12 mainly comprises two clamping plates 121 which are slidably connected with the supporting plate 11, a supporting plate 124 is detachably connected to the lower portion of the clamping plate 121, the supporting plate 124 can be connected with the clamping plate 121 through screws, the side face of the supporting plate 124 is planar or arc-shaped (the side face of the supporting plate 124 is planar in fig. 1 and 3 and the side face of the supporting plate 124 is arc-shaped in fig. 5 and 6), and the supporting plate 124 can be inserted into the connecting hole 21 of the metal copper-based lead frame 2.
The lifting rod 13 is movably arranged above the support plate 11, and the two clamping plates 121 are symmetrically arranged on the left side and the right side of the lifting rod 13.
One end of each transmission rod 14 is hinged with the lifting rod 13, the other end of each transmission rod is hinged with the clamping plate 121, when the lifting rod 13 moves upwards, the two clamping plates 121 of the clamping plate group 12 can be close to each other, and when the lifting rod 13 moves downwards, the two clamping plates 121 of the clamping plate group 12 can be far away from each other; the transmission rods 14 are multiple, and the number of the transmission rods 14 is equal to that of the clamping plates 121.
A driving source, which is mounted on the support plate 11 for moving the lifting rod 13 in the vertical direction, may be, for example, a cylinder 151.
The connection mechanism 16 is used to connect the output end of the drive source and the lifting lever 13.
As can be seen from the above, after the supporting plate 124 of the clamping plate set 12 is inserted into the connection hole 21 of the metal copper-based lead frame 2, the driving source drives the lifting rod 13 to move down to separate the two clamping plates 121 of the clamping plate set 12 from each other, and at this time, the side surfaces of the two supporting plates 124 can contact with the inner sides of the connection hole 21, so that the metal copper-based lead frame 2 is picked up by the supporting plate 124 of the clamping plate set 12. The clamping plate 121 only drives the supporting plate 124 to move, the side surfaces of the supporting plate 124 are planar or arc-shaped, the supporting plate 124 and the clamping plate 121 are arranged in a detachable mode, and the corresponding supporting plate 124 is convenient to replace according to the shape of the connecting hole 21 of the metal copper-based lead frame 2, for example, when the shape of the connecting hole 21 is circular, the supporting plate 124 with the arc-shaped side surfaces is arranged on the clamping plate 121, so that the supporting plate 124 and the inner wall of the connecting hole 21 can have larger contact area, which is beneficial to increasing friction force between the supporting plate 124 and the connecting hole 21, and therefore the supporting plate 124 of the clamping plate group 12 can be ensured to pick up the metal copper-based lead frame 2 stably.
When there are a plurality of clamping plate groups 12 (for example, four clamping plate groups 12 can be respectively contacted with the connecting holes 21 at four corners of the metal copper-based lead frame 2), the lifting rods 13 are also a plurality, and only one cylinder 151 needs to be configured to synchronously drive each lifting rod 13 to move through the connecting mechanism 16, so that the number of driving sources is reduced, and the equipment investment cost is reduced.

The connection mechanism 16 may mainly include a connection rod 161, one end of the connection rod 161 being connected to an output end of the driving source, and the other end being directly or indirectly connected to the lifting lever 13. When the movable end of the cylinder 151 moves upwards, the lifting rod 13 also moves upwards; when the movable end of the air cylinder 151 moves downward, the lifting rod 13 also moves downward.
The connection mechanism 16 may further include: a vertical bar 162 and a horizontal plate 163; the vertical rod 162 is directly or indirectly connected with the support plate 11; the vertical rod 162 is inserted into the transverse plate 163 to guide the longitudinal movement of the transverse plate 163; the lifting rod 13 is fixed to the transverse plate 163, and one end of the connecting rod 161 is connected to the transverse plate 163 so as to drive the lifting rod 13 to move through the transverse plate 163.
