In order to achieve the purpose, the utility model adopts the technical proposal that: a crown block anti-falling mechanism with a telescopic antenna comprises a bottom plate, a sliding seat driving mechanism, a main connecting rod, an auxiliary connecting rod and an antenna connecting rod; the sliding seat driving mechanism drives the sliding seat to slide on the bottom plate, and an anti-falling material fork and a connecting rod shifting lever are arranged on the sliding seat; the connecting rod deflector rod is used for driving the main connecting rod to rotate, the main connecting rod drives the antenna connecting rod to rotate through the auxiliary connecting rod, and the antenna connecting rod is provided with the RFID antenna.
Preferably, the bottom plate is further provided with an inductor.
Preferably, the slide seat driving mechanism comprises a motor, a synchronous belt, a screw rod, a sliding rail and a sliding block.
Preferably, the slide seats are divided into a front slide seat and a rear slide seat, and the front slide seat and the rear slide seat are driven by the slide seat driving mechanism to synchronously slide; the front sliding seat is provided with an anti-falling material fork, and the rear sliding seat is provided with a connecting rod deflector rod.
Because of the application of above-mentioned technical scheme, compared with the prior art, the utility model has the following advantage:
the utility model discloses the overhead traveling crane anti-falling mechanism of flexible antenna in area of scheme has designed the antenna follow-up structure of many connecting rods, makes the antenna receive inside the frame at ordinary times, treats that the wafer box snatchs the back that targets in place, and the antenna is again along with preventing that the mechanism is together stretched out, avoids interfering with the object in the transport, causes equipment and raw materials to damage, the cost is reduced and safe risk.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-4, the anti-falling mechanism for overhead travelling crane with telescopic antenna according to the present invention is designed based on the existing anti-falling mechanism for the bottom of overhead travelling crane for transporting wafer boxes; the crown block anti-falling mechanism with the telescopic antenna comprises a bottom plate 41, a sliding seat 42, a sliding seat driving mechanism 43, a main connecting rod 44, an auxiliary connecting rod 45 and an antenna connecting rod 46; the bottom plate 41 is fixedly installed at the bottom of the crown block, the slide seat driving mechanism 43 can adopt a transmission mechanism consisting of a motor, a synchronous belt, a screw rod, a slide rail and a slide block, the slide seats 42 are divided into a front slide seat and a rear slide seat, and the front slide seat and the rear slide seat 42 are driven by the slide seat driving mechanism 43 to synchronously slide; the front slide seat 42 is provided with an anti-falling material fork 47, and the rear slide seat 42 is provided with a connecting rod deflector rod 48.
After the two sliding seats 42 slide forwards to the right position, the anti-falling material fork 47 at the front side can clamp the bottom of the wafer box to prevent the wafer box from falling; meanwhile, during the extending process of the rear sliding seat 42, the link rod deflector rod 48 drives the main link rod 44 to rotate; specifically, a long slot structure is formed in the middle of the link lever 48, one end of the link lever 48 enters the slot structure, the rear end of the main link 44 is hinged to the bottom plate 41, and the link lever 48 can drive the main link 44 to rotate in the process of moving along with the slide 42.
The front end of the main link 44 is hinged to one end of the auxiliary link 45, the other end of the auxiliary link 45 is hinged to the middle of the antenna link 46, and the rear end of the antenna link 46 is hinged to the bottom plate 41, so that the main link 44 can drive the antenna link 46 to rotate through the auxiliary link 45.
The front end of the antenna connecting rod 46 is provided with an RFID antenna 49, and after the antenna connecting rod 46 extends out, the front end of the antenna connecting rod is located at the label of the wafer box, so that the RFID antenna 49 can identify the label of the grabbed object.
The split structure of the two sliding seats 42 can prevent the stress of the anti-falling material fork 47 from being directly born on the sliding seat of the connecting rod deflector rod 48, and the situation that the antenna is blocked and cannot extend out is avoided.
