Technical Field
[0001] The utility model relates to the technical field of vibration feeding, in particular to a lens pressure ring feeding system. Background Art
[0002] The optical imaging lens includes a lens barrel, a lens group and a pressure ring. The pressure ring is the last assembly component on the optical imaging lens assembly accessories. The entire lens group is limited and fixed in the lens barrel by gluing the pressure ring to the lens barrel. The pressure ring plays a role in packaging and fixing the optical imaging lens.
[0003] At present, on the automatic assembly line of optical imaging lenses: (1) During the loading process, the front and back facing compression ring materials need to be sorted. The traditional sorting method is to use a photoelectric sorter to sort according to the surface or density difference of the compression ring materials. However, there are problems such as inaccurate and unreliable sorting due to different batches of surface treatment of the compression ring materials; (2) The traditional loading system is an integrated receiving structure. When the assembly machine on the assembly line takes materials from the receiving structure, the compression ring materials transported from the front and back will come into contact with each other and cause interference, which is not conducive to the assembly machine taking materials.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A lens pressure ring feeding system comprises a vibration disk, a front and back side distinguishing jig, a straight vibration track, a separate material receiving device and an assembly machine; the front and back side distinguishing jig comprises a distinguishing tooth plate and a distinguishing limit plate, the distinguishing tooth plate is connected to the disk surface track of the vibration disk, and has a wavy tooth groove along the length direction, the distinguishing limit plate is fixed parallel to the upper surface of the distinguishing tooth plate, and its inner side wall is spaced apart from the inner side wall of the distinguishing tooth plate to form a distinguishing track; the straight vibration track is connected to the disk surface outlet; the separate material receiving device is spaced apart at the discharge end of the straight vibration track, and a material receiving groove corresponding to the discharge port of the straight vibration track is provided on the top of the separate material receiving device, the groove bottom of the material receiving groove is lower than the groove bottom of the straight vibration track, and both sides of the material receiving groove are provided with in-place optical fiber probes, which are used to detect whether the pressure ring material is in place; the assembly machine is arranged on one side of the separate material receiving device, and is used to take material from the material receiving groove according to the detection situation of the in-place optical fiber probe.
[0007] In some embodiments, a drop groove is provided on the surface of the vibration disk below the distinguishing tooth plate, and unqualified pressure ring materials fall back into the vibration disk through the drop groove after distinguishing the front and back sides.
[0008] In some embodiments, the feeding system further comprises a three-axis manual displacement platform, which is installed on one side below the separate material receiving device and connected to the separate material receiving device for adjusting the position of the separate material receiving device. In at least one embodiment, the separate material receiving device comprises a receiving block, a fixing plate and an adapter plate which are overlapped and fixedly connected in sequence from top to bottom; the receiving groove is provided on the receiving block; the in-place optical fiber probe is installed on both sides of the fixing plate; and one end of the adapter plate is connected to the top of the three-axis manual displacement platform.

When the pressure ring material passes through the distinguishing track, since one side of the pressure ring material is provided with a convex ring and the other side is a plane, when the pressure ring material is in a state where the convex ring surface faces downward, due to the wavy tooth groove arranged on the distinguishing tooth plate, the contact area between the convex ring and the distinguishing tooth plate is small, and the vibrating disc vibrates, and the pressure ring material with the convex ring surface facing downward falls from the distinguishing tooth plate back into the vibrating disc because it is not stable enough; when the pressure ring material is in a state where the plane faces downward, the contact area between the plane and the distinguishing tooth plate is large, and it can be transported to the straight vibration track through the distinguishing track, thereby mechanically sorting the pressure ring material with the front and back sides facing upward. Compared with the photoelectric sorting machine, it will not cause inaccurate and unreliable sorting due to different batches of surface treatment of the pressure ring material, and can accurately sort;
[0011] 2. The separate material receiving device of the utility model is arranged at intervals at the discharge end of the straight vibration track, and a material receiving trough corresponding to the discharge port of the straight vibration track is arranged on the top thereof.
