[0056] In one embodiment, if Figure 6 and Figure 7 As shown, the blanking mechanism 6 includes a bottom plate 61, a top plate 62, a mold drive 63, a mold assembly 64, a plurality of guide rods 65 and a support plate 66 provided with a plurality of through holes; one end of the guide rod 65 is connected to the top plate 62, and the other end of the guide rod 65 passes through the through hole and is connected to the bottom plate 61; the mold drive 63 is installed on the support plate 66 and connected to the bottom plate 61, and is used to drive the bottom plate 61 to drive the top plate 62 to rise and fall through the guide rod 65; it can be understood that the mold drive 63 includes but is not limited to a linear motor, a pneumatic cylinder, a hydraulic cylinder and a screw nut mechanism; the support plate 66 is located between the top plate 62 and the bottom plate 61, that is, the top plate 62 is fixed to the upper end of the guide rod 65, and the bottom plate 61 is fixed to the lower end of the guide rod 65.

[0057] The mold assembly 64 includes an upper mold 641, a support seat 642 and a lower mold 643 installed on the support seat 642; the upper mold 641 is installed on the plate surface of the top plate 62 facing the support plate 66, and the support seat 642 is installed on the plate surface of the support seat 642 facing the top plate 62.

[0058] Specifically, when the mold-closing driving member 63 drives the bottom plate 61 to move up and down, the bottom plate 61 drives the top plate 62 to move closer to or away from the support plate 66 through the guide rod 65, so that the top plate 62 can drive the upper mold 641 to close or open the mold with the lower mold 643. When the upper mold 641 and the lower mold 643 are closed, the upper mold 641 can punch out the blanking piece on the lower mold 643, and punch out the blanking piece into a waste frame and a plurality of finished products. In this embodiment, the punching mechanism 6 has a compact structure and occupies little space.

[0059] In one embodiment, if Figure 7 and Figure 8 As shown, the support seat 642 is also provided with a plurality of accommodating holes and threaded holes connected to the accommodating holes, and the lower mold 643 is provided with a sliding hole connected to the accommodating holes; it can be understood that the threaded hole is located at the bottom of the accommodating hole, and the threaded hole is coaxially arranged with the accommodating hole.

[0060] The mold assembly 64 also includes a plurality of buffer assemblies 644, each of which includes a first screw 6441 and an elastic member 6442 sleeved on the first screw 6441, one end of the first screw 6441 is threadedly connected to the threaded hole, the other end of the first screw 6441 passes through the receiving hole and then slides into the sliding hole, the elastic member 6442 is located in the receiving hole and the opposite ends are respectively abutted against the lower mold 643 and the support seat 642; a compression space is provided between the lower mold 643 and the support seat 642. It can be understood that the shapes of the upper mold 641 and the lower mold 643 can be designed according to actual needs; the number of the buffer assemblies 644 can be designed according to actual needs, for example, the buffer assemblies 644 are provided with 4, 6, 8, etc.; the elastic member 6442 includes but is not limited to springs, etc.

[0061] Specifically, when the mold closing drive member 63 does not drive the upper mold 641 and the lower mold 643 to close the mold, due to the rebound force of the elastic member 6442, a compression space (not shown in the figure) is provided between the lower mold 643 and the support seat 642, that is, the lower mold 643 is located above the support seat 642 and does not abut against the support seat 642.

[0062] When the mold-closing driving member 63 drives the upper mold 641 to close the mold with the lower mold 643, the upper mold 641 punches the workpiece to be punched on the lower mold 643, and the lower mold 643 moves up and down on the support seat 642 and compresses the elastic member 6442, so that the elastic member 6442 can absorb the punching force of the upper mold 641 on the lower mold 643, thereby preventing the upper mold 641 from crushing the lower mold 643. In this embodiment, the structure of the buffer assembly 644 is simple, which reduces the manufacturing cost of the automatic punching equipment.

[0063] In addition, the user can adjust the depth of the first screw 6441 inserted into the threaded hole (that is, the size of the compression space between the upper mold 641 and the support seat 642) through the first screw 6441, since the first screw 6441 is threadedly connected to the threaded hole, thereby adjusting the pre-tightening force of the elastic member 6442. In this embodiment, the first screw 6441 can adjust the pre-tightening force of the elastic member 6442 on the lower mold 643, thereby improving the applicability and versatility of the automatic punching equipment.

[0064] In one embodiment, if Figure 6 and Figure 7 As shown, the punching mechanism 6 also includes a first slider 67 installed on the support seat 642 and a support block 68, a first guide rail 69 and a horizontal driving member 601 all installed on the support plate 66, the first slider 67 is slidably connected to the first guide rail 69, and the horizontal driving member 601 is used to drive the support seat 642 to slide along the first guide rail 69 through the first slider 67; it can be understood that the horizontal driving member 601 includes but is not limited to a linear motor, a pneumatic cylinder, a hydraulic cylinder and a screw nut mechanism; in the process of the horizontal driving member 601 driving the support seat 642 to move, the support seat 642 slides on the first guide rail 69 through the first guide rail 69, thereby ensuring the stability of the movement of the support seat 642.

[0065] The support block 68 is used to support the support seat 642 when the upper mold 641 and the lower mold 643 are closed.

[0066] Specifically, when the horizontal driving member 601 drives the support seat 642 and the lower mold 643 away from the bottom of the top plate 62, the loading robot 3 can place the workpiece to be punched on the lower mold 643, and the transfer robot 5 can grab the waste frame and finished workpiece on the upper mold 641. In this embodiment, the design of the horizontal driving member 601 facilitates the loading and unloading of the lower mold 643.

[0071] Specifically, the clamping drive 43 drives the second screw 47 to rotate, and the second screw 47 drives the first carrier plate 452 to move by being threadedly connected to the first external thread through the first nut. Since the pitches of the multiple first external threads are not equal, the distance between the multiple first carrier plates 452 can be changed, that is, the spacing between the multiple first suction nozzle assemblies 45 is adjusted, and then the unloading robot 4 can suck multiple finished parts (circuit boards, etc.) of different sizes and different spacings, thereby improving the applicability and versatility of the unloading robot 4.

In this embodiment, when the clamping drive 43 drives the second screw 47 to rotate, in the same equal pitch thread group, the opening and closing degrees of the first air nozzle assembly and the second air nozzle assembly are equal.

[0075] Specifically, the rotation of the second screw 47 can drive the first air nozzle assembly and the second air nozzle assembly to move closer to the middle or open to both ends, thereby improving the compactness of the blanking robot 4.
