When the slide rod 102c-1 pushes the base plate 102c-1c to move, due to the blocking effect of the blocking plate 102c-1f on the inclined plate 102c-1d, the inclined plate 102c-1d can drive the ratchet 104b-1 to rotate by cooperating with the ratchet 104b-1. During the resetting process of the placement table 105, the compression resetting of the fourth spring 102c-1e can enable the placement table 105 and the slide rod 102c-1 to be smoothly reset.

[0038] In addition, an electric push rod 106 is fixedly connected to one side of the substrate 102a, and the output end of the electric push rod 106 is fixedly connected to the first engaging plate 106a and the second engaging plate 106b.

When the punching is completed, the electric push rod 106 is reset first.

[0039] When in use, first place the circuit board that needs to be punched on the upper end surface of the placement table 105 to facilitate the initial positioning of the circuit board, then turn on the motor 101a, the motor 101a rotates forward, and can drive the nut 101c to move upward through the screw 101b. At this time, the contact block 101c-1 slides along the inclined surface of the inclined block 102d, and the first spring 102b is reset, which can drive the two displacement plates 102c to approach each other. The circuit board on the upper end of the placement table 105 can slide along the curved surface of the upper end of the support plate 102c-3 to the upper end of the support plate 102c-3. At this time, the third spring 103b is compressed, and the roller 103c can press and position the upper end of the circuit board. In addition, the rolling of the roller 103c will not affect the contact process between the circuit board and the baffle 102c-1a, and can adapt to circuit boards of different widths to perform adaptive clamping and positioning of the circuit boards.

[0040] Example 2 Reference Figure 1 - Figure 6 Based on the previous embodiment, this embodiment provides a PCB circuit board processing and punching device, wherein the placement table 105 includes a torsion member 105a and a transmission member 105b, the torsion member 105a is arranged on the side of the placement table 105, and the transmission member 105b cooperates with the torsion member 105a.

[0042] Furthermore, the transmission member 105b includes a protrusion 105b-1 and an elastic rope 105b-2, the protrusion 105b-1 is fixedly connected to the bottom of the placement table 105, one end of the elastic rope 105b-2 is fixedly connected to the protrusion 105b-1, and the other end of the elastic rope 105b-2 is wound around the wire wheel 104b-2.

[0043] It should be noted that, Figure 1 - Figure 6 The structure in the figure is only used as a reference for mechanical transmission and is not a structural proportional diagram of the final product.

[0044] When in use, first place the circuit board that needs to be punched on the upper end surface of the placement table 105 to facilitate the initial positioning of the circuit board, then turn on the motor 101a, the motor 101a rotates forward, and can drive the nut 101c to move upward through the screw 101b. At this time, the contact block 101c-1 slides along the inclined surface of the inclined block 102d, and the first spring 102b is reset, which can drive the two displacement plates 102c to approach each other. The circuit board on the upper end of the placement table 105 can slide along the curved surface of the upper end of the support plate 102c-3 to the upper end of the support plate 102c-3. At this time, the third spring 103b is compressed, and the roller 103c can press and position the upper end of the circuit board. In addition, the rolling of the roller 103c will not affect the contact process between the circuit board and the baffle 102c-1a, and can adapt to circuit boards of different widths to perform adaptive clamping and positioning of the circuit boards.

[0045] As the two displacement plates 102c continue to approach each other, the circuit board can come into contact with the baffle 102c-1a, and the baffle 102c-1a can squeeze the second spring 102c-2, so that the slide bar 102c-1 drives the transmission member 102c-1b to move, and the transmission member 102c-1b can drive the ratchet 104b-1 to rotate by cooperating with the ratchet 104b-1, and the ratchet 104b-1 drives the wire wheel 104b-2 to rotate through the rotating shaft 104b to achieve the effect of winding the line, and the wire wheel can be wound through the elastic rope 105b -2 drives the placement table 105 to tilt downward, and the torsion spring 105a-3 is twisted at this time. Since the area of ​​the placement table 105 may be large, this process can prevent the placement table 105 from affecting the punching process of the circuit board, and has better practicality. After the punching is completed, the contact block 101c-1 slides downward along the inclined surface of the inclined surface section 102d. At this time, the roller 103c rolls on the upper end of the circuit board, and the torsion spring 105a-3 is reset. After the punching is completed, the circuit board will fall on the upper end surface of the placement table 105, which is convenient for the staff to remove and perform subsequent operations.
