Description

Technical Field

[0001] The invention relates to the technical field of magnetron production equipment, in particular to a magnetron assembly antenna forming and correction machine. Background Art

[0002] The magnetron is a core component of a microwave oven. It consists of numerous components, including an anode assembly, cathode assembly, and antenna assembly, and is manufactured through numerous processes, including assembly, welding, and processing. To ensure the emission of microwaves generated by the magnetron, the magnetron core contains an antenna connected to the anode vane. During the magnetron core production process, the antenna must be bent into a specific shape to ensure coaxial assembly with the core. With technological advancements, the production and processing of magnetrons has gradually evolved into a modular, assembly-line process, which improves magnetron production efficiency and quality. In practice, magnetron antennas are typically pre-formed before assembly. However, during automated assembly, welded magnetron antennas sometimes inevitably experience unintended deformation. Excessive deviations can lead to significant errors in precision work at certain automated production lines, potentially damaging workpieces and even production equipment. Therefore, it is necessary to design a magnetron antenna re-forming device for automated magnetron production lines to correct the magnetron antenna's shape and ensure the safety of subsequent processing.

DETAILED DESCRIPTION

[0022] Example:

[0023] 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.

[0024] 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.

[0025] Referring to the accompanying drawings, a magnetron assembly antenna forming and correction machine is shown, comprising an anode tube antenna assembly feed line 1 and an antenna forming and correction assembly. The anode tube antenna assembly feed line 1 is used to convey anode tube antenna assemblies 2 and is provided with an antenna forming and correction station, at which the antenna forming and correction assembly is located. The antenna forming and correction assembly includes an antenna positioning mechanism and an antenna pressing mechanism. The antenna positioning mechanism is used to position and restrict the anode tube antenna assembly 2, and the antenna forming and correction assembly is used to press-fit the antenna. The magnetron assembly antenna forming and correction machine of this embodiment is a device used in a streamlined production line for magnetron tube core assemblies. The workpiece conveying line of the tube core assembly streamlined production line serves as the anode tube antenna assembly feed line 1 of the magnetron assembly antenna forming and correction machine of this embodiment. Specifically, the antenna 201 has been welded to the anode blade of the magnetron core assembly, and the magnetron core assembly is transported along the line for related process steps. In order to ensure the accuracy and safety of subsequent assembly actions, the magnetron core assembly is transported along the line to the corresponding position of the magnetron assembly antenna forming and correction machine in this embodiment, and the magnetron core assembly is positioned at the predetermined antenna forming and correction station position. At this time, the antenna forming and correction assembly executes the action to press-fit and correct the antenna 201 on the magnetron core assembly to ensure the coaxiality of the antenna 201 and the magnetron core assembly, so as to ensure that the subsequent production and assembly actions of the magnetron core assembly streamlined production line can be carried out smoothly, and the accuracy and safety of the operation can be guaranteed.

[0026] The assembly line production of magnetron core assemblies typically involves placing the relevant magnetron core assemblies on a positioning jig 3 that is conveyed along the line. To facilitate loading and unloading of the magnetron core assemblies, the positioning jig 3 generally does not secure the magnetron core assemblies thereon. Therefore, before performing the molding and correction of the antenna 201, the anode tube antenna assembly 2 must be restrained and secured. Specifically, as shown in the accompanying drawings, the antenna positioning mechanism in this embodiment includes a pair of opposing anode tube positioning plates 4. A molding gap is formed between the anode tube positioning plates 4, allowing the antenna molding and correction assembly to press-fit the antenna 201. After the anode tube antenna assembly 2 is conveyed along the line and positioned at the antenna molding and correction station, the anode tube positioning plates 4 move downward to secure the anode tube antenna assembly 2 below. A molding gap is reserved between the anode tube positioning plates 4 for the antenna molding and correction assembly to operate. The antenna molding and correction assembly then performs molding and correction of the antenna 201 on the anode tube antenna assembly 2 from both sides.

[0027] Specifically, the anode tube antenna assembly 2 is a whole, in which the anode tube is the largest component, and it is suitable to fix the assembly through the anode tube. As a feasible implementation method, in this embodiment, the anode tube positioning plate 4 is an embedded plate, that is, the anode tube positioning plate 4 extends into the inner side of the anode tube and fits the inner surface of the anode tube, and restricts and fixes the anode tube antenna assembly 2 from the inner side of the anode tube to ensure that the antenna forming correction assembly can smoothly perform the antenna molding correction action. It is easy to understand that the embedded plate fixing method of this embodiment is only one of the feasible implementation methods. It can also be achieved by restricting and fixing from the outside of the anode tube through an external embedded plate or by restricting and fixing from the upper side of the anode tube through an upper embedded plate. The principles of these restrictive fixations are the same, and there are certain differences only in the restricting position and the end structure of the anode tube positioning plate 4. In actual applications, it can be flexibly set and adjusted as needed.

[0028] As described above, when the present embodiment uses an embedded plate to restrict and fix the anode tube antenna assembly 2 from the inside of the anode tube, the preferred implementation of the embedded plate is to use an arc positioning surface adapted to the inner side surface of the anode tube to better fit and restrict the inner side surface of the anode tube, thereby forming a stable restrictive positioning effect.

[0029] The anode cylinder positioning plate 4 with the above-mentioned structural arrangement can be made of metal material to ensure structural strength. In actual applications, on the one hand, it is necessary to ensure that the anode cylinder positioning plate 4 can be extended into the inner side of the anode cylinder. On the other hand, due to the certain error in the in-line conveying positioning of the anode cylinder antenna assembly 2, in order to avoid crushing the workpiece or the anode cylinder positioning plate 4, as shown in the accompanying drawings, in this embodiment, a first chamfered portion 401 is provided at the front end of the embedded plate. Based on the setting of the first chamfered portion 401, the minimum radial diameter of the front end of the embedded plate is smaller than the inner diameter of the anode cylinder. Even under a certain positioning error, it can be ensured that the embedded plate can be smoothly extended into the inner side of the anode cylinder and the anode cylinder antenna assembly 2 can be restricted and fixed, thereby avoiding the occurrence of the above-mentioned fault.

[0030] Based on the above-described structural arrangement of this embodiment, the antenna shaping and correction assembly performs die-forming and correction on antenna 201 on anode tube antenna assembly 2 from both sides. Specifically, the antenna shaping and correction assembly comprises a first die assembly 5 and a second die assembly 6. As shown in the accompanying drawings, antenna 201 has a multi-section curved structure and must be installed perpendicularly relative to anode tube antenna assembly 2 to ensure coaxiality. To this end, the first die assembly 5 and the second die assembly 6, when combined, press antenna 201 on anode tube antenna assembly 2 into the desired shape, correcting deviations of antenna 201 caused by previous steps and ensuring the accuracy and safety of subsequent production and assembly operations.

[0031] As shown in the accompanying drawings, as a feasible embodiment, the first die assembly 5 in this embodiment is a slot die, and the second die assembly 6 is a matching male die. During the closing process of the first and second die assemblies 5 and 6, the slot die restrains the antenna 201, and the closing action of the two assemblies moving toward each other extrudes and corrects the antenna 201 to a relatively vertical installation position. Specifically, as shown in the accompanying drawings, the first die assembly 5 in this embodiment includes a side die plate 501 and a bottom die plate 502. The side die plates 501 are disposed on either side of the bottom die plate 502, and when assembled, the two form the slot die structure. In a preferred embodiment, a second chamfer 503 is provided at the front end of the side die plate 501, so that the slot die has a relatively wide opening. Even if the antenna 201 on the anode tube antenna assembly 2 is significantly deformed, it can still smoothly enter the slot die opening under the guidance of the second chamfer 503, thereby achieving the closing correction.

[0032] In the streamlined production line for magnetron core assemblies, the anode tube antenna assembly 2 is typically conveyed horizontally. Therefore, the preferred method for restraining and securing the anode tube antenna assembly 2 is along its axis. To this end, as shown in the accompanying drawings, the antenna positioning mechanism in this embodiment is positioned along the axis of the anode tube antenna assembly 2. Once the anode tube antenna assembly 2 is positioned, the anode tube positioning plate 4 is driven up and down to restrain and release the anode tube antenna assembly 2. This simple structure eliminates the need for complex detection and control. On the other hand, based on the structural characteristics of the anode tube antenna assembly 2, the antenna 201 is welded and fixed on the anode blade, and the anode blade is located in the middle section of the anode tube and its height is less than the height of the anode tube, that is, the extrusion correction of the antenna 201 is hindered to a certain extent by the anode tube. For this reason, a preferred embodiment is shown in the accompanying drawings, wherein the first die assembly 5 and the second die assembly 6 are arranged at an angle to the radial direction of the anode tube antenna assembly 2, and the two are clamped in a manner inclined relative to the horizontal plane. In addition, in the convex mold of the second die assembly 6, the avoidance notch 601 at the lower front end is structurally designed to avoid the obstruction of the anode tube, so that the first die assembly 5 and the second die assembly 6 can be clamped in a single motion mode to achieve extrusion correction of the antenna 201, and the operation of the equipment is more accurate and reliable, thereby reducing the failure rate of the magnetron assembly antenna forming and correction machine equipment.

[0033] 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.
