Description

Carrier motion
Technical Field
The utility model belongs to the technical field of the carrier transmission technique and specifically relates to a carrier motion is related to.
Background
In an automated production apparatus in the electronic industry, to complete automatic or semi-automatic assembly, testing, and the like of a product, a carrier for carrying the product needs to be used for transferring the product in a flow channel, and the flow channel mainly serves to transfer and precisely position the carrier. In the prior art, when the carrier is transferred and precisely positioned, the products in the carrier cannot be assembled, tested and the like, so that the transfer time and the precise positioning time of the carrier influence the beat of equipment. In the prior art, the carrier moves by driving a screw nut pair to move back and forth along a track by a motor. An upper positioning pin for positioning a carrier is fixed on an upper positioning pin fixing plate, a lower positioning pin is fixed on a lower positioning pin fixing plate, corresponding positioning pin holes are formed in the carrier, and the upper positioning pin and the lower positioning pin are driven to move simultaneously through a cylinder.
The complete movement process of the mechanism is as follows: the cylinder rises, and the follower drives upper locating pin and lower locating pin to rise, and upper locating pin breaks away from the locating pin hole on the carrier, and lower locating pin gets into in the locating pin hole, and the effect of lower locating pin is mainly the fore-and-aft movement of dragging the carrier. The motor operates, the lower positioning pin fixing plate is driven to move forwards through the lead screw, the lower positioning pin fixing plate, the lower positioning pin and the carrier move forwards, after the carrier is taken to a working station, the motor stops operating, the air cylinder descends, the upper positioning pin enters the positioning pin hole to position the carrier, and the lower positioning pin is separated from the carrier. At the moment, the work station can assemble (glue, weld, test and the like) the products in the carrier, when the carrier works at the work station, the motor runs in the reverse direction, the lower positioning pin is brought back to the initial position, and after the assembly is finished, the next cycle of movement is carried out.
The operation process of the carrier in the prior art is as follows: the lower positioning pin is set to be in an initial state at a falling position,
