Cordless spring-system curtain inspection device

A cordless spring-system curtain inspection device, comprising:

• a test stand and a curtain-opening and-closing drive mechanism disposed on the test stand, wherein the curtain-opening and-closing drive mechanism comprises a clamping mechanism configured to clamp a lower beam of a curtain and a lower-beam lifting drive mechanism configured to drive the clamping mechanism to move reciprocally and linearly,
• wherein the clamping mechanism is disposed on a clamping sliding platform to be driven by the lower-beam lifting drive mechanism for linear movement;
• the clamping mechanism comprises a first clamping member and a second clamping member that are disposed on the clamping sliding platform, the first clamping member and the second clamping member forming a clamping groove;
• the clamping groove is driven by a clamping drive mechanism disposed on the clamping sliding platform to be contracted or opened, so as to open or close the clamping mechanism;
• the clamping mechanism is provided with a lower-beam position-inspecting mechanism configured to inspect whether the lower beam is in place;
• and the curtain-opening and-closing drive mechanism is electrically connected to a programmable logic controller (PLC).
