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,

the cylinder rises and the lower locating pin enters the carrier locating hole →:

motor drives down locating pin and drags carrier to work station →

Air cylinder falls down, lower positioning pin is separated from carrier →

Assemble the product in the carrier (the lower positioning pin can be driven by the motor to return to the original position during the assembly) →

And (3) lifting the follower cylinder, enabling the lower positioning pin to enter the tooling positioning hole, wherein the four actions are in series connection, and each action cannot be saved, wherein the third step is the moving process of the carrier. The existing mechanism has complex structure and process of conveying the carrier and longer time; in order to ensure the accuracy of the in-place of the carrier, the clearance between the lower positioning pin and the positioning pin hole of the carrier is about +/-0.03 mm, and the upper positioning pin is difficult to position due to overlarge clearance, so that the requirements on the accuracy of the position degree and the hole size of the positioning pin hole in the fixing plate of the lower positioning pin are very high, and the processing cost is high; the runner with the length of 900mm needs three lower positioning pin fixing plates, so that the distance between the positioning pin holes at the joint of the two positioning plates needs to meet the distance between the carriers, the processing difficulty and the cost are increased, and the debugging difficulty is also high.
