Description

Swing arm type screw feeding device

Technical Field

The utility model relates to the technical field of automatic screw locking, in particular to an automatic swing arm type screw feeding device.

Background

With the rapid development of the electronic industry, the requirements on the manufacturing technology of electronic products are higher, the procedures on the production line for manufacturing the electronic products are more and more complex, and the screw locking is a very complex and high-requirement basic work. The traditional screw locking equipment has low precision and complex operation, and along with the continuous improvement of technical requirements, the new generation screw locking equipment gradually has the characteristics of high precision and simple operation.

Screw locking machines generally comprise a feed section for supplying material (screws) and a suction locking section for sucking up the material and performing the screw locking operation. In the prior art, a screw feeder belonging to a feeding part mainly comprises a roller 01, a vibrating channel 02, a dividing disc 03 and a feeding sensor 04 in structure, as shown in figure 1.

The working principle of the existing screw feeder is that the screw placed in the feeding device is transferred into the vibration material channel 02 through the rotation of the roller 01, the vibration material channel 02 transmits the vibration of the screw to the position of the dividing disc 03 through the vibration of the vibration material channel 02, the dividing disc 03 rotates the screw to the position of the material sensor 04 through rotation (generally clockwise rotation), if the material sensor 04 does not sense that the screw exists at the set position, the dividing disc 03 continues to rotate until the material sensor 04 senses that the screw exists at the set position, a material signal is transmitted to the control module, and the control module sends a signal to the screw machine head (sucking and locking part) and drives the screw machine head to suck the screw to be sucked at the set position and perform subsequent screw locking work, so that the feeding operation of the screw is sequentially circulated.

In order to solve the above-mentioned problems that in the prior art, the screw machine head needs to wait for feeding and take materials back and forth during the feeding operation, and occupies most of time, and the working speed is very slow, resulting in low operation efficiency of the device, the inventor proposes an improved screw vibration feeding device (patent application number: 202022912936.5), in the scheme of the feeding device, as shown in fig. 2, the material distributing portion 20 includes a material pulling cylinder 202 and a material pulling sheet 201 driven by the material pulling cylinder 202, and a material pulling opening for individually dividing screws is provided on the material pulling sheet 201, and the material pulling opening can be aligned to the tail outlet of the long material chute 104. In the process of feeding and cutting screws, after the screws are vibrated out from the tail of the long material groove 104, the screws fall into a material pulling opening formed in the material pulling sheet 201, the material pulling cylinder 202 drives the material pulling sheet 201 to divide (or "cut") the screws, meanwhile, the correlation sensor 203 detects the corresponding positions, if no screw signal is detected, the material pulling cylinder 202 drives the material pulling sheet 201 to return, and the material pulling opening is continuously aligned to the tail screw outlet of the long material groove 104, if a screw signal is detected, the material pulling step (division) is completed. Then, the first lifting cylinder 401 drives the first suction pipe 402 to approach the material pulling port to suck the divided screw therein, then lifts off, and finally conveys the divided screw into the confluence device 60 for the suction locking operation of the screw machine locking suction head.

Due to the continuous improvement of the requirements of electronic consumer products in the industry, the miniaturization and refinement of electronic components are continuously promoted, correspondingly, the requirements on fasteners such as screws are also increasingly miniaturized, in the production practice, small screws of M0.6 and M0.5 are common, and the trend of miniaturization is developing. This places a higher demand on the accuracy of the operation of the screw locking machine. For example, the miniaturization of the screw leads to the defects of serious mutual friction, screw drop, screw clamping and the like of the traditional screw machine feeding device, and the reason is that the screw machine vibration feeding channel and the tiny screw conveying clearance are matched, if the matching problem cannot be effectively solved, the operation efficiency of the screw machine is directly affected, and finally the use cost of equipment is increased.

Therefore, the above-mentioned shortcomings of the feeding device of the conventional automatic screw locking machine on the market are the problems to be solved in the industry.
