Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a nut conveyor. Background Art

[0002] Nut conveyors are mainly used in the automotive and motorcycle fields. Their function is to arrange the nuts in a certain posture and then input them into the spot welding machine for welding. Conventional nut conveyors use a vibrating plate to arrange the nuts in a specific posture, and then use a distributor to input the nuts into the spot welding machine for processing.

[0003] Since the volume of the vibrating plate is small, nuts need to be added to the plate when there is a shortage of material. The traditional method is manual addition, which results in high labor costs and has been gradually eliminated. The existing method is to install a material shortage sensor in the vibrating plate to detect whether there are enough nuts in the vibrating plate. When the number of nuts is insufficient, the storage hopper will be controlled to discharge the material accordingly, thereby adding nuts to the vibrating plate. The existing material shortage sensor generally adopts a pendulum-type sensor. The structure of the pendulum-type sensor can refer to CN217101687U. The applicant believes that the pendulum of the existing pendulum-type sensor can only swing within one plane, and its detection accuracy needs to be improved. Utility Model Content

The vibrating plate 2 and the storage trough are installed on the base 1. A bracket 3 is installed on the base 1. The height of the upper part of the bracket 3 is higher than the height of the top of the vibrating plate 2. The bracket 3 is connected to the first cross arm 31, the second cross arm 32 and the third cross arm 33 from bottom to top above the vibrating plate 2. A horizontal lower connecting ring 4 is fixed to the second cross arm 32. The top of the lower connecting ring 4 is connected to the upper connecting ring 5 by multiple bolts. The inner walls of the lower connecting ring 4 and the upper connecting ring 5 are located on the same spherical surface. The lower connecting ring 4 and the upper connecting ring 5 are connected. A ball head 6 is installed in the ring 5. The bottom of the ball head 6 is connected to a connecting rod 61 pointing to the center of the ball. The bottom of the connecting rod 61 is connected to a C-shaped frame 7. The bottom of the C-shaped frame 7 is connected to a pendulum rod 8. The pendulum rod 8 is coaxial with the connecting rod 61 and the pendulum rod 8 is eccentrically arranged in the vibration disk 2. A light-transmitting channel 62 coaxial with the connecting rod 61 is formed between the top of the ball head 6 and the bottom of the connecting rod 61. A photoelectric receiver 9 and a photoelectric generator 10 are respectively installed at the positions corresponding to the ball head 6 on the first cross arm 31 and the third cross arm 33. The photoelectric receiver 9 is located in the C-shaped frame 7. When the lower connecting rod 61 is set vertically, the photoelectric generator The light beam emitted by the photoelectric generator 10 can pass through the light-transmitting channel 62 and be received by the photoelectric receiver 9.
