Technical Field

The invention relates to the technical field of automatic screw locking, in particular to a blowing device for blowing screws in a screw machine.

Background

In recent years, the electronic industry has been developed rapidly, the requirements for the manufacturing technology of electronic products are higher and higher, and the processes on the production line for manufacturing electronic products are more and more complex, wherein the screw locking is a very complicated and high-requirement basic work. The traditional screw locking equipment is low in precision, complex to operate and poor in universality. With the continuous improvement of technical requirements, the new generation of screw locking equipment gradually has the characteristics of high precision, simple operation and strong universality.

The screw locking machine generally includes a feeding portion for supplying a material (screw) and a suction locking portion for sucking the material and performing a screw locking operation. In the prior art, a feeder of a screw machine, which belongs to a feeding part, is mainly composed of a roller 01, a vibrating material channel 02, a dividing disc 03 and a material sensor 04 in structure, as shown in fig. 1.

The working principle of the feeder of the existing screw machine is that screws arranged in the feeder are transmitted to the vibrating material channel 02 through rotation of the roller 01, the vibrating material channel 02 transmits the screw vibration to the dividing disc 03 through self vibration, the dividing disc 03 rotates the screws to the material sensor 04 through rotation (generally clockwise rotation), if the material sensor 04 does not sense that the screws exist at the set position, the dividing disc 03 continues to rotate until the material sensor 04 senses that the screws are at the set position, a material signal is transmitted to the control module, the control module sends a signal to a screw machine head (a suction locking part) and drives the screw machine head to suck the screws to be sucked at the set position and perform subsequent screw locking operation, and the feeding operation of the screws is performed in sequence and circularly.

In order to solve the problems that in the feeding operation process of the feeder of the screw machine in the prior art, the screw machine head needs to wait for feeding and take materials back and forth, occupies most of the time, and has a slow working speed, so that the operation efficiency of the equipment is low, the inventor provides an improved screw vibration feeding device (patent application number: 202022912936.5). in the scheme of the feeding device, as shown in fig. 2, a material distributing part 20 comprises a material pulling cylinder 202 and a material pulling sheet 201 driven by the material pulling cylinder 202, a material pulling port for singly dividing the screw is arranged on the material pulling sheet 201, and the material pulling port can be aligned with an outlet at the tail part of the long trough 104. In the screw feeding and cutting process, the screws fall into the material pulling openings formed in the material pulling sheet 201 after the tails of the long material grooves 104 are vibrated out, the material pulling cylinder 202 drives the material pulling sheet 201 to cut (or cut) the screws, meanwhile, the corresponding positions are detected by the correlation sensor 203, if no screw signal is detected, the material pulling cylinder 202 drives the material pulling sheet 201 to return, the material pulling openings are continuously aligned with the tail screw outlets of the long material grooves 104, and if a screw signal is detected, the material pulling step (cutting) is completed. Then, the first elevating cylinder 401 drives the first suction pipe 402 to approach the drawing port to suck the screw divided therein, then lifts it away, and finally conveys the divided screw to the manifold 60 for a suction locking operation of the screw machine for locking the suction head.

In the screw is cut and is absorb transportation process to the screw after the step, there is the time delay in the cylinder drive straw motion, and in addition, the process that the straw absorbs the screw has taken more time, leads to feed speed not to lift up, and production efficiency is not high.
