[0002] A micro switch is a switch with a small contact spacing and a snap-action mechanism. It is a contact mechanism that performs switching actions with a specified stroke and a specified force. It is covered with a shell and has a driving rod on the outside. Because the contact spacing of the switch is relatively small, it is called a micro switch, also known as a sensitive switch.

[0003] In the prior art, two rivet points are riveted on the wiring terminals in the micro switch. During the production process, some wiring terminals have only one or no rivet point, and these terminals are unqualified products. Currently, manual visual inspection is performed, but long-term manual observation can easily cause blurry eyesight, which not only results in poor inspection results, but also makes the workers more tired, resulting in poor inspection results for the wiring terminals of the micro switch.

[0022] Embodiment 1

[0023] like Figure 1 - Figure 4 As shown, the utility model provides an automatic screening feed tray for micro switch terminal blocks, including a mounting base 1, a feed tray 3 is fixedly connected to the upper end of the mounting base 1, a material placement cavity 4 is arranged inside the upper end of the feed tray 3, a vertical sleeve plate 9 is fixedly connected to the outlet of the material placement cavity 4, one end of the vertical sleeve plate 9 is fixedly connected to a No. 1 transmission plate 10, a screening trough 17 is opened on one side of the middle part of the No. 1 transmission plate 10, a limiting strip 16 is arranged on one side of the screening trough 17, and the limiting strip 16 and the No. 1 transmission plate 10 are of an integrated design.

[0024] The specific settings and functions of this embodiment are described in detail below. Through the settings of the screening trough 17 and the limiting strip 16, when unqualified micro switch terminals pass through, the terminals that lack a rivet point will tilt, and through gravity, the position of the terminals will change, and they will fall from the gap between the screening trough 17 and the limiting strip 16, and the terminals without rivet points will directly slide out from between the limiting strip 16 and the screening trough 17. In this way, the micro switch terminals can be quickly screened, and the employees only need to put the terminals into the device, thereby improving the detection efficiency of the terminals and reducing the fatigue of the workers.

[0025] Embodiment 2

[0026] like Figure 1 - Figure 4 As shown, the outer edge of the upper end of the feed tray 3 is fixedly connected with an outer cover 5, the vertical sleeve plate 9 and the first transmission plate 10 are both located inside the outer cover 5, and a discharge plate 13 is fixedly connected to one side of the outer cover 5, one end of the discharge plate 13 is located below the screening trough 17, and the screening trough 17 is of an inclined design, one end of the first transmission plate 10 is fixedly connected with the second transmission plate 14, and the upper end of the second transmission plate 14 is provided with a pressing plate 15, and the pressing plate 15 is fixedly connected to the feed tray 3, and the outer cover 5 is fixedly connected to the discharge plate 13, and the discharge plate 13 is fixedly connected to the discharge plate 13, and the discharge plate 13 is fixedly connected to the discharge plate 13. The upper end of the cover 5 is fixedly connected with the No. 1 rod 6 and the No. 2 rod 7, and the upper end of the outer cover 5 is provided with the No. 4 rod 11 and the No. 3 rod 8. The No. 3 rod 8 is located at the entrance of the No. 1 transmission plate 10, and the No. 4 rod 11 is located on one side of the screening trough 17. One end of the No. 4 rod 11 and the No. 3 rod 8 is fixedly connected with a connecting plate 12, and the connecting plate 12 is fixedly connected to the outer cover 5. The four corners of the mounting seat 1 are provided with mounting grooves 2, and a gap is left between the lower end of the discharge plate 13 and the lower end of the outer cover 5.

[0027] The effect achieved by the entire embodiment is that, through the arrangement of the No. 1 rod 6, the No. 2 rod 7 and the No. 3 rod 8, when the micro switch flows into the vertical sleeve plate 9, the inclined surface of the vertical sleeve plate 9 changes, and the wiring terminals are gradually adjusted to a vertical state, and the stacked terminals are pushed out by the No. 1 rod 6, and the No. 2 rod 7 cooperates with the No. 3 rod 8 to limit the individual terminals so that the terminals flow into the No. 1 transmission plate 10. In this way, the automatic adjustment of the terminals can be achieved, which is convenient for use. Through the arrangement between the discharge plate 13 and the outer cover 5, the stacked and pushed out terminals will gradually flow out from the lower end of the outer cover 5, and the terminals can be recovered in this way for re-inspection, and the discharge plate 13 can collect the screened unqualified terminals, and a collection box can be placed at the lower end of the discharge plate 13 for use, which is convenient for collection. A gap is arranged between the vertical sleeve plate 9 and the outer ring surface of the No. 1 transmission plate 10, and the No. 1 transmission plate 10 is an arc-shaped rotating design. After the terminals pass through the limiting strip 16, the qualified terminals are gradually adjusted to a horizontal state.

[0028] The method of use and working principle of the device are as follows: when in use, the produced micro switch terminal blocks are placed in the material placement cavity 4, and then the feeding tray 3 is started, so that the terminals flow out of the material placement cavity 4 one by one, and pass through the vertical sleeve plate 9, and gradually adjust the terminals to be close to vertical, and the stacked terminals are pushed down to the inside of the outer cover 5 by the No. 1 rod 6, and then the terminals pass through the No. 2 rod 7 and the No. 3 rod 8, and the No. 2 rod 7 and the No. 3 rod 8 further adjust the terminals and guide them to the No. 1 transmission plate 10, and then the terminals move to the limiting strip 16 and the screening trough 17, and qualified terminals will pass directly, and defective terminals will pass through directly. The terminal with one less rivet point will tilt, and its position will change due to its own gravity, flowing out from between the limiting strip 16 and the screening slot 17, and falling on the discharge plate 13. The terminal without a rivet point will directly slide out from between the limiting strip 16 and the screening slot 17, and fall on the discharge plate 13. Then the terminal will fall from the discharge plate 13 into the storage box. The qualified terminal will enter between the No. 2 transmission plate 14 and the pressing plate 15. At this time, the No. 2 transmission plate 14 and the pressing plate 15 are in a horizontal state. Then the terminal is connected to the conveying equipment and sent to the next process.
