The invention relates to the technical field of wafer carrying, in particular to wafer multi-piece type mechanical arm carrying equipment which comprises an X-axis transplanting platform arranged in an equipment body, the upper surface of the X-axis transplanting platform is connected with a protective shell, and two sets of symmetrically-arranged servo motors are fixedly installed in the protective shell; a synchronous wheel set is fixedly installed at the output end of each servo motor, a ball screw is inserted into the other end of each synchronous wheel set, two symmetrically-arranged connecting plates are connected to the surface of each ball screw in a meshed mode, material taking plates are fixedly installed at the tail ends of the multiple connecting plates, and a center plate is arranged in the middle of the multiple material taking plates. And the center plate is fixedly mounted on the surface of the protective shell. Through cooperative use of all parts, multiple groups of wafers can be carried at a time, wafers of different specifications can be carried, and the purposes of accelerating the carrying period and improving the carrying efficiency are achieved.

The utility model discloses an intake manifold support's structure, the utility model relates to intake manifold support technical field, including first support and second support, first support and second support one end surface all are provided with mounting hole, the inside of first support is close to second support one end and is provided with adjusting mechanism. This intake manifold support's structure, through the recess of the groove of the limiting rod and the surface of the rotating ring is separated, can rotate second support, and subsequently let the limiting rod into the recess, prevent rotating ring and second support and rotate, improved stability, and through the connecting spring can make the baffle automatic reset, make the baffle and the circular ring stopper contact together, prevent the limiting rod movement, can stably prevent rotating ring and rotate, improved stability, make second support surface mounting hole can with different installation position alignment, adapt to different installation environment, improved adaptation range.

The utility model provides a kind of electric screwdriver with separable feeding nozzle, including seat, electric driver, screw feeding nozzle, screw butt joint nozzle, driving mechanism and control circuit board, electric driver is set on seat, screw feeding nozzle has guide through-hole and feeding through-hole, the pivot of electric driver is slidably inserted into guide through-hole;Feeding through-hole is communicated with guide through-hole, to make screw be transported from feeding through-hole to the discharge port of guide through-hole;Driving mechanism is set on seat and drives screw feeding nozzle to move along the central axis direction of the pivot of electric driver;Screw butt joint nozzle is fixed to seat, and screw feeding nozzle is slid to its upper limit of stroke and butt joint with screw butt joint nozzle, to receive the screw exported from screw butt joint nozzle;Screw feeding nozzle is separated from screw butt joint nozzle when sliding downward in its upper limit of stroke.The utility model electric screwdriver with separable feeding nozzle of driving mechanism of the utility model is light in load, and the speed of driving screw is fast, and the service life of driving mechanism is long.
