Abstract
Description
Technical Field
[0001] This utility model relates to the field of stud feeder technology, and more specifically, it relates to a stepped feeder for conveying wiring studs. Background Technology
[0002] In the PCB assembly process, the terminal stud is a key connecting element. Its structure, with an external thread on one end and an internal thread on the other, presents considerable challenges in the feeding and sorting of the stud. During the feeding process, the terminal stud may be in three states: upright, lying flat, or upside down. The upside-down state is the ideal state for screening. Upright means the internal thread end is facing up and the external thread end is facing down. Lying flat means the internal thread end and the external thread end are set horizontally. Upside down means the external thread end is facing up and the internal thread end is facing down.
[0003] Currently, when the connecting studs are directly conveyed to the screening position, the lack of a transition step after conveying causes the center of gravity of the connecting studs to be unstable. The studs may enter the groove in an upright position, which not only increases the screening difficulty but may also reduce screening efficiency. Furthermore, dust or debris easily accumulates in the feeder hopper during prolonged operation. These impurities may mix into the connecting studs, causing equipment malfunctions, interfering with the normal conveying and screening of the connecting studs, and potentially damaging the feeder's internal mechanisms, increasing equipment maintenance costs and downtime.
[0004] Therefore, a stepped feeder for conveying wiring studs is proposed to solve the above problems. Utility Model Content

The screening assembly includes a first feeding plate, a second feeding plate on the side of the first feeding plate away from the stepped feeding mechanism, and a connecting plate between the first and second feeding plates, the connecting plate being located away from the tilting mechanism.
[0008] By adopting the technical scheme, the connecting plate lays the wiring studs, stabilizes the gravity centers of the wiring studs, and then queues and screens, so that the screening quality and efficiency are improved.

[0010] The utility model further sets up: hopper bottom plate is away from the one side of stepped feeder mechanism and is provided with inclined plate, and the vibration mechanism is set up at the bottom of inclined plate.

[0028] Please refer to Figure 5, the hopper assembly 3 has a hopper bottom plate 31, the hopper bottom plate 31 is arranged close to the stepped feeding mechanism 4, a plurality of filter holes 32 are arranged on the top end of the hopper bottom plate 31, and the ash hopper 8 is arranged below the hopper bottom plate 31. The inclined plate 33 is arranged on the side of the hopper bottom plate 31 away from the stepped feeding mechanism 4, and the vibration mechanism 7 is arranged at the bottom end of the inclined plate 33.
[0029] Through the cooperation of the filter holes 32 and the vibration mechanism 7, the dust or debris accumulated at the bottom end of the hopper assembly 3 is vibrated out of the hopper assembly 3 while the vibration wiring stud is being vibrated, and the falling dust or debris is collected through the ash hopper 8. After the equipment works for a period of time, the operator can take out the ash hopper 8 to dump the collected dust or debris, avoiding the problem of equipment failure caused by the accumulation of dust or debris, and improving the cleanliness and stability of the equipment.
[0030] Referring to Figure 6 , the screening assembly 5 includes a first feeding plate 51, the first feeding plate 51 is fixedly connected with the stepped feeding mechanism 4, the second feeding plate 52 is arranged on the side of the first feeding plate 51 away from the stepped feeding mechanism 4, the connecting plate 53 is arranged between the first feeding plate 51 and the second feeding plate 52, and the connecting plate 53 is arranged away from the turnover mechanism 6.
