[0014] like Figure 1-4 As shown, the utility model provides a power relay feeding device, including a support plate 1, a feeding slide 2 arranged on the support plate 1, a feeding slot 3 being arranged on the feeding slide 2, and also including a driving motor 4 arranged on the support plate 1, pulleys 5 arranged at both ends of the feeding slide 2, a feeding belt 6 arranged on the pulley 5, and an optical fiber sensor 7 arranged on one side of the discharge end of the feeding slide 2, the pulley 5 corresponds to the feeding slot 3 on the feeding slide 2, the upper end surface of the pulley 5 is higher than the bottom of the feeding slide 2, and the lower end surface is lower than the lower end surface of the feeding slide 2, the feeding belt 6 is sleeved on the two pulleys 5, the driving motor 4 is connected to the pulley 5 in transmission, and the sensing end of the optical fiber sensor 7 faces the feeding slot 3 of the feeding slide 2.

[0015] The feeding slot 3 on the feeding slide 2 is a slot-type structure with openings at both ends. The feeding belt 6 is installed on two pulleys 5. The upper part of the feeding belt 6 is located in the feeding slot 3 and the lower part is located at the lower end of the feeding slide 2. It moves in a ring around the slot bottom and the lower end of the feeding slide 2. The shape of the feeding slot 3 is adapted to the power relay. During feeding, the power relay enters the feeding slot 3 from the feeding end of the feeding slide 2. At this time, the power relay is located on the feeding belt 6 in the feeding slot 3. The driving motor 4 drives the pulley 5 to rotate, driving the feeding belt 6 to move in the feeding slot 3. The movement of the feeding belt 6 drives the power relay to move in the feeding slot 3 to realize feeding. Controlling the driving motor 4 can control the movement and stop of the power relay. The feeding is stable and easy to use. The optical fiber sensor 7 can perform in-place detection to provide a signal basis for the start and stop of the driving motor 4. The design has stable transportation, precise control, simple structure, low cost and easy use.

[0016] like Figure 2 As shown, it also includes a feeding base 8 arranged on the support plate 1, a belt groove 9 arranged at the upper end of the feeding base 8, the lower end of the pulley 5 corresponds to the belt groove 9, and the feeding slide 2 is arranged at the upper end of the feeding base 8 and closes the belt groove 9.

[0017] The lower part of the feeding belt 6 is in the belt groove 9, and the feeding belt 6 is protected by the belt groove 9, which also prevents people from accidentally touching it. At the same time, the feeding belt 6 is limited and guided to prevent the feeding belt 6 from deviating.

[0018] like Figure 4 As shown, it also includes a mounting seat 10 arranged on one side of the discharge end of the feeding slide 2, a torsion spring arranged on the mounting seat 10 and a damping baffle 11 arranged on the torsion spring. The damping baffle 11 is installed on the mounting seat 10 with the help of the torsion spring, and the front end of the damping baffle 11 extends into the feeding slot 3 from the discharge port of the feeding slide 2.

[0019] When the power relay moves to the discharge end of the feeding chute 2, continuing to move will push the damping baffle 11 outward. Under the action of the torsion spring, the damping baffle 11 will continue to be pressed against one side of the power relay to play a damping role. The power relay will not fall from the feeding chute 2 until it slides out of the feeding slot 3 as a whole, thus preventing the power relay from sliding out of the feeding slot 3 as a whole after the driving motor 4 stops. This reduces the difficulty of feeding control and makes feeding more accurate.

[0020] like Figure 4 As shown, the sensing end of the optical fiber sensor 7 corresponds to the end of the damping baffle 11 extending into the feeding slideway 2.

[0021] The optical fiber sensor 7 corresponds to the damping baffle 11 in position, providing a more accurate control signal for the control of the drive motor 4, further improving the accuracy of feeding.
