DETAILED DESCRIPTION

[0024] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] like Figure 1 The magnetron end cap vibrating feed tray shown in the figure comprises a vibrating feed tray 1, a spiral feeding channel 2 and a screening and sorting feed channel, wherein the spiral feeding channel 2 spirally rises from the bottom of the vibrating feed tray 1 along the side wall of the vibrating feed tray 1 to the upper part of the vibrating feed tray 1, and the screening and sorting feed channel is connected to the upper end of the spiral feeding channel 2; the screening and sorting feed channel comprises a single workpiece feeding channel 3, a flip feeding channel 4, a first screening feeding channel 5, a second screening feeding channel 6 and a flip sorting feeding channel 7; the feed channel width of the single workpiece feeding channel 3 is not greater than the maximum size of the magnetron end cap 8 and is connected to the discharge end of the spiral feeding channel 2; the flip feeding channel 4 is connected to the single workpiece feeding channel 3. A turning step 9 is formed below the discharge end of the workpiece feeding channel 3 and between the single workpiece feeding channel 3; the first screening feeding channel 5 is connected to the discharge end of the flipping feeding channel 4, and the first screening feeding channel 5 is provided with a first screening blanking structure for performing a primary screening of the magnetron end caps 8; the second screening feeding channel 6 is connected to the discharge end of the first screening feeding channel 5, and the second screening feeding channel 6 is provided with a second screening blanking structure for performing a secondary screening of the magnetron end caps 8; the flipping sorting feeding channel 7 is connected to the discharge end of the second screening feeding channel 6, for turning and sorting the magnetron end caps 8.

[0027] The vibrating feeding plate of this embodiment is designed with a structure of multiple sub-channels for screening and sorting the material channels, and a corresponding screening and blanking structure is designed according to the structural characteristics of the magnetron end cap 8. The vibrating feeding plate 1 can automatically complete the screening and adjustment of the direction of the magnetron end cap 8 during the vibration feeding process, so that the material is always fed in a unified direction, realizing the automatic sorting and feeding of the magnetron end cap 8, facilitating the grasping and assembly mechanism to perform the grasping and assembly action, and improving the assembly efficiency and assembly quality.

[0028] For details, see the attached Figure 3 As shown, the magnetron end cap 8 of this embodiment is generally in the shape of a cylindrical cover with a small top and a large bottom, and its maximum dimension is the height H of the magnetron end cap 8. A number of magnetron end caps 8 are poured into the vibrating material tray 1. Under the action of the continuous vibration driven by the vibration mechanism at the bottom of the vibrating material tray 1, the magnetron end caps 8 slowly rise along the spiral feeding channel 2. Since the width of the spiral feeding channel 2 is relatively wide, the rising rate of the magnetron end cap 8 can be guaranteed. However, the spiral feeding channel 2 lacks corresponding structural restrictions, resulting in different shapes of the rising magnetron end caps 8, such as forward, reverse, horizontal, upright, inverted, parallel and stacked states, which need to be screened, adjusted and sorted through subsequent screening and sorting channels. First, it goes through the first structural screening, that is, screening is performed through the single-workpiece feeding channel 3 connected to the discharge end of the spiral feeding channel 2. Since the width of the single-workpiece feeding channel 3 does not exceed the height H of the magnetron end cap 8, only a single row of magnetron end caps 8 are allowed to move, so as to achieve the effect of screening and removing the magnetron end caps 8 that move side by side. Then it enters the second structural screening, that is, screening is performed through the flipping feeding channel 4 connected to the discharge end of the single-workpiece feeding channel 3. Through the setting of the flipping step 9 at the connection between the single-workpiece feeding channel 3 and the flipping feeding channel 4, there is a height difference between the two channels. According to the structural size characteristics of the magnetron end cap 8 of this embodiment, through the reasonable height setting of the flipping step 9, a flipping action can be performed after passing through the flipping step 9, and the state of the magnetron end cap 8 after flipping is improved to meet the next screening. Since the state of the magnetron end cap 8 when entering the single workpiece feeding channel 3 is uncertain, and there is also randomness when performing the flipping action through the flipping step 9, the state of the magnetron end cap 8 after the reversal is not unique. At this time, the magnetron end cap 8 entering the first screening feeding channel 5 needs to be further screened. According to the structural size characteristics of the magnetron end cap 8, the magnetron end cap 8 that does not meet the sorting requirements can be screened out by reasonably setting the first screening blanking structure. After the previous several structural screenings, the magnetron end cap 8 that meets the sorting requirements can basically be screened out. In this embodiment, the second screening blanking structure of the second screening feeding channel 6 ensures that it enters the flipping sorting feeding channel 7 in the correct state for the most comprehensive adjustment and sorting, so that the magnetron end cap 8 can be fed in a unified direction, which is convenient for the subsequent automated assembly operation mechanism to perform the grabbing assembly action, and improves the assembly efficiency and assembly quality.

[0029] As mentioned above, in order to increase the vibration feeding speed of the magnetron end cap 8, the width of the spiral feeding channel 2 in this embodiment is greater than the maximum size of the magnetron end cap 8. The magnetron end cap 8 is not easy to fall back to the bottom of the vibrating material tray 1 when moving upward along the spiral feeding channel 2, ensuring that the magnetron end cap 8 continuously enters the screening and sorting channel for screening and sorting.

[0030] In a preferred embodiment, see Figure 1 As shown, in this embodiment, a weight-removing side wall plate 10 is provided at the junction of the spiral feeding channel 2 and the single workpiece feeding channel 3, and the weight-removing side wall plate 10 is extended from the outside to the inside. As mentioned above, the feeding magnetron end caps 8 may have the problem of stacking and traveling. Through the provision of the weight-removing side wall plate 10 in this embodiment, when the magnetron end caps 8 enter the single workpiece feeding channel 3, the weight-removing side wall plate 10 can act on the magnetron end caps 8 so that the magnetron end caps 8 stacked on the upper side fall back to the bottom of the vibrating material tray 1, which is conducive to removing the overlapping magnetron end caps 8.

[0031] As a feasible implementation method, see the attached Figure 1 As shown, the first screening and blanking structure of this embodiment includes a first blanking notch 11 and a screening guide rod 12. The width of the first blanking notch 11 is smaller than the width of the first screening feed channel 5. The screening guide rod 12 is arranged inside the first blanking notch 11. The structural design of the first screening and blanking structure of this embodiment can screen out magnetron end caps 8 that are moving in the forward, reverse, upright, and partially horizontal directions.

[0032] See attached Figure 2 As shown, in this embodiment, the width of the feed end of the second screening feed channel 6 is smaller than the maximum size of the magnetron end cap 8. After the screening in the aforementioned steps, only the magnetron end caps 8 in the inverted state and occasionally in the lateral state can pass through the above-mentioned first screening feed channel 5. For this reason, in order to screen out these individual magnetron end caps 8 in the lateral state, the feed end of the second screening feed channel 6 is set to be smaller than the height H of the above-mentioned magnetron end cap 8. When the magnetron end cap 8 enters the second screening feed channel 6 in the lateral state, it cannot be stably supported and thus falls back to the bottom of the vibrating material tray 1. That is, only the magnetron end cap 8 in the inverted state can continue to move along the second screening feed channel 6.

[0033] See attached Figure 3 As shown, in actual application, in order to facilitate the grabbing and assembly of the magnetron end cap 8, the magnetron end cap 8 vibration feeding tray finally needs to adjust the magnetron end cap 8 to the attached Figure 3In the upright state shown, in order to improve the adjustment efficiency, the second screening blanking structure of this embodiment includes a second blanking notch 13 and a flip slope 14, and the flip sorting feed channel 7 is connected to the low side of the flip slope 14, and the second blanking notch 13 is set on the high side of the flip slope 14. When the magnetron end cap 8 moves to the flip slope 14, under the action of the slope and its own gravity, the magnetron end cap 8 can flip sideways into the flip sorting feed channel 7. If it fails to flip in, it will fall back to the bottom of the vibrating material tray 1 along the second blanking notch 13.

[0034] See also Figure 1 As shown, in this embodiment, the flipping and sorting feeding channel 7 includes a flipping trough 701 and a sorting trough 702. The direction of the magnetron end cap 8 is gradually flipped by the flipping trough 701, and the discharge end of the sorting trough 702 forms a discharge port of the magnetron end cap 8. The magnetron end cap 8 is flipped and enters the flipping and sorting feeding channel 7. Under the adjustment action of the flipping trough 701 and the sorting trough 702, it is finally adjusted to an upright state and discharged from the final discharge port of the magnetron end cap 8, thereby realizing automatic feeding of the magnetron end cap 8.

[0035] In a preferred embodiment, as shown in the accompanying drawings, a flip pressure rod 15 is provided on the opening side of the flip trough 701 to prevent the magnetron end caps 8 from stacking or falling out in the flip sorting feeding channel 7, so as to feed the materials one by one in an orderly arrangement. In this embodiment, the sorting trough 702 is tilted from high to low, and the discharge port of the magnetron end caps 8 is located at the lower end of the sorting trough 702. In addition to the vibration feeding effect, the magnetron end caps 8 in the sorting trough 702 also have a tendency to slide downward. When the magnetron end cap 8 at the discharge port of the front magnetron end cap 8 is removed and loaded, the subsequent magnetron end caps 8 can quickly fill the vacancy, thereby ensuring the accuracy of the feeding action of the magnetron end cap 8 vibration feeding tray.

[0036] The above description is only for the preferred embodiment of the present invention, which should not be construed as limiting the claims. The present invention is not limited to the above embodiment, and its specific structure is allowed to be varied. In short, all variations made within the scope of protection of the independent claims of the present invention are also within the scope of protection of the present invention.
