Description

Technical Field

[0001] The invention relates to a clamping mechanism, in particular to an automatic clamping mechanism for conductive foam. Background Art

[0002] Conductive foam refers to a flame-retardant sponge wrapped with conductive cloth. After a series of treatments, it has good surface conductivity and can be easily adhered to shielding devices with tape.

[0003] In industrial production projects, conductive foam needs to be transported to the required location for easy handling. The current commonly used method for transporting conductive foam is to use a single cylinder and a clamping plate assembly to clamp the conductive foam. However, during the clamping process, the weak holding force provided by the single cylinder and the clamping angle result in poor clamping stability, causing the conductive foam to fall during transportation. Since there is no detection part in the clamping mechanism, the clamping mechanism fails to clamp the conductive foam or the conductive foam falls during transportation, and the clamping mechanism cannot detect it. Therefore, continuous clamping force is required to prevent it from being missed or falling. In addition, when transporting the conductive foam, its direction cannot be adjusted, which leads to deficiencies in the needs of different workstations.

[0004] In view of this, the present invention designs an automatic conductive foam clamping mechanism. Summary of the Invention

A through slide is slidably installed in the groove chamber, and the through slide passes through the limiting slide groove and extends to the outside of the Z-direction stand, and the two horizontal mounting frames are respectively fixedly installed on both sides of the through slide.

[0011] Preferably, a Z-axis one-way screw is rotatably installed in the groove chamber, and a through slide is threadedly installed on the Z-axis one-way screw. A No. 1 servo motor is fixedly installed on the top of the Z-axis stand, and the output end of the No. 1 servo motor is fixedly connected to the Z-axis one-way screw.

[0012] Preferably, a PLC controller is fixedly mounted on the upper end of the Z-axis stand, and servo motor No. 1, servo motor No. 2 and servo motor No. 3 are all electrically connected to the PLC controller.

[0033] Specifically, a slot chamber is provided inside the Z-axis stand 2, and both side walls of the slot chamber are provided with limit slides 26. A through slide 24 is slidably installed in the slot chamber, and the through slide 24 passes through the limit slide 26 and extends to the outside of the Z-axis stand 2. Two horizontal mounting frames 3 are respectively fixedly installed on both sides of the through slide 24.

The press switch 17 is pressed once for one operation, that is, the first operation is clamping, and the second operation is releasing, and so on. It can work continuously on the production line and improve work efficiency.

[0038] During the process of transferring the conductive foam, the No. 3 servo motor 13 can also be started to rotate the No. 1 bevel gear 14. Under the meshing transmission between the No. 1 bevel gear 14 and the No. 2 bevel gear 15, the No. 2 bevel gear 15 drives the transposition rotation shaft 12 to rotate, so as to change the direction of the conductive foam to adapt to the work station requirements and be more flexible.
