[0002] The magnetron is a core component of a microwave oven. It consists of numerous components, including the anode, cathode, and antenna assemblies, and is manufactured through numerous processes, including assembly, welding, and processing. In modern industrial production, automated production lines are often used to improve efficiency and quality. The magnetron assembly process includes a step where the A-side pole piece is assembled with the anode cylinder assembly. Automated feeding of the A-side pole piece is essential for automating this assembly step. The A-side pole piece is the one that attaches to the magnetron's antenna end and features an antenna hole that allows the antenna to pass through during assembly. To facilitate automated assembly of the A-side pole piece, it must be aligned in a uniform direction to facilitate the gripping and assembly process. The A-side pole piece is a small, straw-hat-shaped component, necessitating a tailored automatic feeding mechanism to meet the requirements for automated feeding of the A-side pole piece during magnetron assembly.

DETAILED DESCRIPTION

[0021] Example:

[0022] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0024] like Figure 1 As shown, a vibrating feeding tray for A-side magnetic pole pieces comprises a vibrating feeding tray 1, a spiral feeding channel 2 and a screening and sorting channel, wherein the spiral feeding channel 2 spirally rises from the bottom of the vibrating feeding tray 1 along the side wall of the vibrating feeding tray 1 to the upper part of the vibrating feeding tray 1, and the screening and sorting channel is connected to the spiral feeding channel 2 for screening, sorting and conveying the A-side magnetic pole pieces 3; the screening and sorting channel comprises an inclined screening channel 4, a flip feeding channel 5 and a sorting feeding channel 6; the inclined screening channel 4 is connected to the end of the spiral feeding channel 2, and comprises a narrow side channel 401 and a screening inclined surface 402, and the screening inclined surface 402 is located on one side of the narrow side channel 401; the flip feeding channel 5 is connected to the end of the inclined screening channel 4, and comprises a wide side channel 501 located on the side of the narrow side channel 401 relatively away from the screening inclined surface 402; the sorting feeding channel 6 is connected to the end of the flip feeding channel 5, for conveying the screened and sorted A-side magnetic pole pieces 3. The working principle of the vibrating loading tray for the A-side magnetic pole pieces of this embodiment is the same as the basic vibrating feeding principle, that is, the material (A-side magnetic pole pieces 3) is pushed along the material channel by the vibration of the vibrating tray 1. During the material's movement, the A-side magnetic pole pieces 3 that do not meet the sorting state are screened out by the corresponding screening structure set on the screening and sorting channel, and finally the sorting and feeding of the A-side magnetic pole pieces 3 in the established state is achieved. The main feature of this embodiment is that the corresponding screening and blanking structure is designed according to the structural characteristics of the A-side magnetic pole pieces 3, so that the vibrating tray 1 can quickly and accurately automatically complete the adjustment and screening of the direction of the A-side magnetic pole pieces 3 during the vibration feeding process, thereby improving the efficiency of the automatic feeding of the A-side magnetic pole pieces 3.

[0025] In the present invention, the narrow-side material channel 401 refers to a relatively narrow material channel structure designed to suit the thickness parameters of the A-side magnetic pole piece 3, and this narrow material channel structure is used to screen out certain materials that do not conform to the sorting state during the vibration process of the A-side magnetic pole piece 3. Specifically, as shown in the accompanying drawings, the width of the narrow-side material channel 401 is greater than one times the thickness of the A-side magnetic pole piece 3 and less than two times the thickness of the A-side magnetic pole piece 3. The function of the inclined screening material channel 4 is mainly to screen and remove duplicates, and to achieve a single-state movement of materials. For the convenience of description, the screening material inclined surface 402 of the narrow-side material channel 401 in the embodiment is defined as the inner side, and the other side is defined as the outer side; for the A-side magnetic pole piece 3, the side with the larger diameter is defined as the annular surface, and the side with the smaller diameter is defined as the convex surface. As described above, when the A-side magnetic pole piece 3 rises along the spiral feeding channel 2 to the inclined screening channel 4, it slides in with an uncertain posture, including sliding in with the annular surface of the A-side magnetic pole piece 3 attached to the screening material inclined surface 402, sliding in with the convex surface of the A-side magnetic pole piece 3 attached to the screening material inclined surface 402, or sliding in with other postures in between. The purpose of designing the inclined screening channel 4 of this embodiment is to screen out the A-side magnetic pole pieces 3 that slide in with the posture of annular surface attached to the screening material inclined surface 402. Based on the width dimension of the narrow-edge channel 401 and the inclination setting of the screening material inclined surface 402 of this embodiment, combined with the straw hat shape characteristics of the A-side magnetic pole pieces 3, the A-side magnetic pole pieces 3 that slide in with the posture of annular surface attached to the screening material inclined surface 402 can continue to move forward along the inclined screening channel 4 better, while the A-side magnetic pole pieces 3 in other postures fall back into the vibrating material tray 1 and are reloaded due to the lack of support from the narrow-edge channel 401 at the bottom, thereby realizing the screening and feeding of the A-side magnetic pole pieces 3 with the set posture.

[0026] In a preferred embodiment, the slope of the screening material slope 402 gradually increases from the beginning to the end of the inclined screening material channel 4. At the initial end of the inclined screening material channel 4, the relatively small slope setting of the screening material slope 402 can make the A-side magnetic pole piece 3 slide into the inclined screening material channel 4 more smoothly, avoiding the problem that the A-side magnetic pole piece 3 is easily adjusted out and falls back due to excessive movement, so as to ensure that the A-side magnetic pole piece 3 effectively enters the inclined screening material channel 4 for posture screening, thereby ensuring feeding efficiency. At the middle and rear end of the inclined screening material channel 4, the slope of the screening material slope 402 gradually increases until the rear end of the screening material slope 402 is roughly perpendicular to the horizontal plane. The purpose of this slope setting is to gradually lift up the A-side magnetic pole piece 3 during its movement, so that the A-side magnetic pole piece 3 that does not meet the posture requirements loses support and falls off and is screened out, thereby achieving posture screening of the A-side magnetic pole piece 3.

[0027] For details, please refer to the attached Figure 2As shown, in this embodiment, a first auxiliary screening bar 7 is provided on the inclined screening channel 4. The first auxiliary screening bar 7 is disposed outside the narrow channel 401 and extends obliquely in a direction relatively away from the screening inclined surface 402. In actual applications, as described above, the A-side magnetic pole piece 3 may enter the inclined screening channel 4 in various postures. Based on the structural design of the inclined screening channel 4 and the structural characteristics of the A-side magnetic pole piece 3 itself, the A-side magnetic pole piece 3 may also enter and continue to advance in the posture shown in the accompanying drawings, hanging on the narrow channel 401 through the antenna hole 301. To screen out the A-side magnetic pole piece 3 in this posture, in this embodiment, the first auxiliary screening bar 7 is disposed outside the initial end of the narrow channel 401, and the distance between the first auxiliary screening bar 7 and the narrow channel 401 is gradually increased. In this way, when the A-side magnetic pole piece 3 enters the inclined screening channel 4 in the above-mentioned posture and gradually advances, the A-side magnetic pole piece 3 is gradually lifted and flipped upward by the action of the first auxiliary screening bar 7. In the initial stage, since the distance between the first auxiliary screening rod 7 and the narrow side material channel 401 is small, the lower part of the A-side magnetic pole piece 3 can continue to move forward under the joint support of the first auxiliary screening rod 7 and the narrow side material channel 401. However, as the distance between the first auxiliary screening rod 7 and the narrow side material channel 401 gradually increases and eventually exceeds the critical size value, the lower part of the A-side magnetic pole piece 3 loses the support of the first auxiliary screening rod 7. Since the posture of the A-side magnetic pole piece 3 has changed at this time, the single narrow side material channel 401 cannot form a stable support, and the A-side magnetic pole piece 3 will eventually fall back, thereby realizing the screening of the A-side magnetic pole piece 3 in the above-mentioned posture.

[0028] In addition to the above situation, the A-side magnetic pole piece 3 may also enter the inclined screening channel 4 in a manner of overlapping multiple materials. In order to screen out the excess A-side magnetic pole piece 3 in this case, in this embodiment, a second auxiliary screening rod 8 is provided on the inclined screening channel 4. The second auxiliary screening rod 8 is arranged on the outside of the narrow side channel 401 and extends obliquely in a direction relatively close to the screening material inclined surface 402, and forms a screening gap between the second auxiliary screening rod 8 and the screening material inclined surface 402. The width of the screening gap is preferably greater than one times the thickness of the A-side magnetic pole piece 3 and less than two times the thickness of the A-side magnetic pole piece 3. In this way, when multiple (for example, two) A-side magnetic pole pieces 3 overlap and move forward along the inclined screening material channel 4, at the front end of the second auxiliary screening rod 8, since the screening gap between the second auxiliary screening rod 8 and the screening material inclined surface 402 is small, the front end of the second auxiliary screening rod 8 will be inserted into the gap between the innermost A-side magnetic pole piece 3 and its outer A-side magnetic pole piece 3, and then the excess overlapping A-side magnetic pole pieces 3 will fall back under the action of the second auxiliary screening rod 8 when continuing to move forward, thereby realizing the screening of overlapping materials and ensuring the correct posture of the conveying of single materials.

[0029] After being screened by the above-mentioned inclined screening channel 4, the A-side magnetic pole piece 3 is located at the end of the inclined screening channel 4 with its thin edge upright. This posture is unstable and not conducive to transportation, and does not meet the subsequent assembly requirements of the A-side magnetic pole piece 3, requiring further posture adjustment. To this end, this embodiment provides a sheet flip auxiliary rod 9 at the junction between the inclined screening channel 4 and the flip feed channel 5. One end of the sheet flip auxiliary rod 9 is fixed to the screening material inclined surface 402, and the other end extends obliquely toward the wide-side channel. Specifically, as shown in the accompanying drawings, the wide-side channel is arranged outside the narrow-side channel 401 and is lower than the narrow-side channel 401. The A-side magnetic pole piece 3 screened by the inclined screening channel 4 travels to the sheet flip auxiliary rod 9. The sheet flip auxiliary rod 9 acts on the annular surface of the A-side magnetic pole piece 3 to cause it to flip toward the outer wide-side channel, turning it into a horizontal position as shown in the accompanying drawings, which allows for more stable transportation and meets subsequent assembly requirements.

[0030] As shown in the accompanying drawings, preferably, a limiting pressure plate 10 is further provided at the feed port of the sorting feed channel 6. After the A-side magnetic pole piece 3 falls from the narrow side channel 401 to the wide side channel, it is affected by the impact of the falling movement. Not all of the A-side magnetic pole pieces 3 in the wide side channel meet the uniform sorting feeding posture. After the limiting pressure plate 10 is provided, it can be ensured that the A-side magnetic pole pieces 3 finally enter the sorting feed channel 6 in a uniform posture for sorting and feeding.

[0031] After screening and adjustment of the spiral feeding channel 2, the inclined screening channel 4, the flip feeding channel 5 and the sorting feeding channel 6 and other channel structures and the related posture screening structures and posture adjustment structures, the disordered A-side magnetic pole pieces 3 in the vibrating material tray 1 are finally transformed into an orderly and unified manner to realize the automatic feeding of the A-side magnetic pole pieces 3. From the above content, it can be seen that the A-side magnetic pole piece vibrating feeding tray of this embodiment is designed with a plurality of simple structures of the inclined screening channel 4 and the flip feeding channel 5, and the corresponding screening and blanking structure is designed according to the structural characteristics of the A-side magnetic pole pieces 3, so that the vibrating material tray 1 can quickly and accurately automatically complete the adjustment and screening of the direction of the A-side magnetic pole pieces 3 during the vibration feeding process, so that they are finally fed in a unified direction, realizing the automatic sorting and feeding of the A-side magnetic pole pieces 3, facilitating the grasping and assembly mechanism to perform the grasping and assembly action, and improving the assembly efficiency and assembly quality.

[0032] The above description is merely an explanation of the preferred embodiments of the present invention and should not be construed as limiting the claims. The present invention is not limited to the above embodiments, and variations in the specific structure are permitted. In short, all variations made within the scope of the independent claims of the present invention are also within the scope of protection of the present invention.
