Detailed implementation manners

[0021] The present utility model will be further described below with reference to specific embodiments in the accompanying drawings.

[0022] Refer to Figures 1 to 3 , a feeding mechanism for a diamond vibrating bowl, comprising a vibrating bowl 1. An arc-shaped screening channel 2 is provided inside the vibrating bowl 1, and the arc-shaped screening channel 2 is horizontally arranged. One end of the arc-shaped screening channel 2 is connected to the outlet of the spiral conveying channel of the vibrating bowl 1, and the other end of the arc-shaped screening channel 2 is connected to a feeding channel 3. The cross-section of the arc-shaped screening channel 2 is a V-shaped structure. A screening notch 4 is provided at the top of the outer side wall in the middle of the arc-shaped screening channel 2, and the distance B from the screening notch 4 to the root of the outer side wall is 0.4 to 0.5 times the height of the diamond. As Figure 3 shown, the large end of the diamond 25 faces downward, and when the large end of the diamond 25 contacts the inner side wall of the arc-shaped screening channel 2, it is in the correct posture. At this time, the diamond 25 can smoothly pass through the screening notch 4. When the large end of the diamond 25 faces upward, or when the large end of the diamond 25 contacts the outer side wall of the arc-shaped screening channel 2, when passing through the screening notch 4, the large end of the diamond 25 cannot be effectively supported, and thus it falls into the vibrating bowl 1 from the screening notch 4, so as to realize the unified posture conveying of the diamond 25. The feeding channel 3 is located on one side of the outer side wall of the arc-shaped screening channel 2. A feeding port 5 is provided on the outer side wall at the connection of the arc-shaped screening channel 2 and the feeding channel 3. When the diamond 25 reaches the feeding port 5, due to the inclination of the inner side wall of the arc-shaped screening channel 2, the diamond 25 will slide from the feeding port 5 to the feeding channel 3. A sensor 6 for detecting diamonds is provided above the feeding channel 3, which is used for counting and judging whether there is a jam (if no diamond is detected within a set time, it is considered that there is a jam). A front baffle 7 is provided at the end of the feeding channel 3, which is used to block the diamond to achieve accurate positioning of the diamond. Above the end of the feeding channel 3, there are a vacuum chuck 8 for sucking the diamond, a flipping driving member 9 for driving the vacuum chuck 8 to flip, and an up-and-down driving member 10 for driving the flipping driving member 9 to move up and down. The feeding mechanism further includes a controller electrically connected to the vibrating bowl 1, the sensor 6, the vacuum chuck 8, the flipping driving member 9, and the up-and-down driving member 10.

[0023] Specifically, the vibrating bowl 1 is provided with a support cantilever 12 for supporting the arc-shaped screening channel 2, and the vibrating bowl 1 is provided with a support rod 13 connecting the feeding channel 3.

[0024] The feeding channel 3 is of an L-shaped structure, and a side baffle 14 is provided on one side of the feeding channel 3.

[0025] Furthermore, a mounting plate 15 is provided on one side of the feeding channel 3. The mounting plate 15 is provided with locking holes. An adjusting plate 16 is provided at the top of the mounting plate 15. The adjusting plate 16 is provided with an opening U-shaped groove 17. The adjusting plate 16 is locked in the locking hole by an adjusting bolt 18 passing through the opening U-shaped groove 17. The width of the feeding channel 3 is adjusted by adjusting the position of the adjusting plate 16 to ensure accurate positioning of the diamond.

[0026] In this embodiment, the sensor 6 is a photoelectric sensor, the flipping driving member 9 is a rotary cylinder or a motor, and the up-and-down driving member 10 is a cylinder or a hydraulic cylinder or an electric push rod.

[0027] The bottom of the vibrating bowl 1 is provided with foot cups 19 for adjusting the height, which can conveniently adjust the height of the vibrating bowl 1. The bottom of the foot cups 19 is provided with shock pads 20, which can play a role in anti-slip and shock absorption to improve the working stability of the vibrating bowl 1.

[0028] The feeding mechanism further includes a first bracket 21 for mounting the sensor 6 and a second bracket 22 for mounting the up-and-down driving member 10. A guide rail 23 is provided on the side wall of the second bracket 22. A slide table 24 is slidably provided on the guide rail 23. The slide table 24 is connected to the up-and-down driving member 10, and the flipping driving member 9 is mounted on the slide table 24.

[0029] Working principle:

[0030] The vibrating bowl 1 conveys the diamonds to the arc-shaped screening channel 2 and the feeding channel 3. When the diamonds reach the screening notch 4, only the diamonds with the large end facing downwards and the large end contacting the inner side wall of the arc-shaped screening channel 2 can smoothly pass through the screening notch 4. After reaching the feeding channel 3, the large ends of the diamonds face downwards uniformly. When passing through the sensor 6, the controller counts according to the detection result of the sensor 6. If no diamonds are detected within the set time, it is considered that there is a jamming. The controller gives an alarm to remind the worker to check. The vacuum chuck 8 descends to suck up the diamonds at the front baffle 7. After the vacuum chuck 8 rises to the set height, the flipping driving member 9 flips the vacuum chuck 8 by 180°. At this time, the bottom surface of the large end of the diamond faces upwards, which is convenient for the assembly equipment to grab and process in the next process.

[0031] The above is only the preferred embodiment of the present invention. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, and these will not affect the implementation effect of the present invention and the practicality of the patent.
