[0002] Microwave ovens have become a common electrical appliance in people's daily lives, and their related technologies have been quite mature after years of development. Especially in recent years, with the improvement of people's living standards, people's demand for microwave ovens has also increased, which has also stimulated microwave oven manufacturers to carry out technological reforms to improve their production capacity. As the core component of microwave ovens, the efficiency and quality of the production and processing of magnetrons are the top priority of microwave oven production, which is directly related to the production capacity and quality of microwave oven production. Magnetrons are made of many components and parts such as anode components, cathode components and antenna components, which are processed, assembled and welded through many processes.

DETAILED DESCRIPTION

[0029] Example:

[0030] 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.

[0032] like Figure 1 The magnetron end cap automatic assembly system shown in the figure comprises a rotating loading platform 1, a magnetron conveying line 2, an end cap feeding platform 3 and an end cap assembly mechanism; the rotating loading platform 1 comprises a multi-station turntable, a loading robot 4, a functional component and a unloading robot 5; a plurality of magnetron positioning molds 6 are arranged at intervals on the multi-station turntable, and form a magnetron loading station, a functional station and an unloading station respectively with the loading robot 4, the functional component and the unloading robot 5; the magnetron conveying line 2 is connected with the rotating loading platform 1, and the magnetron 7 is transferred from the rotating loading platform 1 to the magnetron conveying line 2 by the unloading robot 5, and the magnetron conveying line 2 is provided with an end cap loading station and an end cap assembly station; the end cap feeding platform 3 is arranged on the end cap loading station, and comprises an end cap loading robot 4; the end cap assembly mechanism is arranged on the end cap assembly station, and comprises an end cap pressing assembly arranged above the magnetron conveying line 2.

[0033] The present invention combines the preliminary inspection process and the end cap assembly process steps of the magnetron 7 to realize automated assembly line operation, realize automatic inspection of the magnetron 7, identify defective products for recycling, and automatically assemble end caps on qualified products, thereby greatly improving the production and processing efficiency of the magnetron 7, while avoiding defective products occupying production equipment resources and wasting raw materials, thereby reducing the overall production cost of the enterprise. The process steps of the automatic assembly system of magnetron end caps of the present invention are as follows: after the magnetron 7 is clamped and sent to the rotating loading platform 1 by the feeding robot 4, the rotating loading platform 1 rotates to make the magnetron 7 transfer to the corresponding functional station, and the functional components on the corresponding station perform corresponding detection operations, and the main control system records the detection results of the magnetron 7; for the magnetron 7 products that pass the detection, they are clamped and sent to the magnetron conveyor line 2 by the unloading robot 5, and the assembly of the magnetron end caps 701 is continued subsequently, and the magnetron 7 products that fail the detection are recycled; during the operation of the system, the end cap feeding platform 3 continues to feed the end caps, and the end cap feeding robot 4 clamps the end cap to the exhaust pipe end of the magnetron 7; when the magnetron 7 with the end cap moves to the end cap assembly station, the end cap assembly mechanism above moves downward to press the end cap tightly, so that the magnetron 7 is attached Figure 2 After the end caps are assembled, the magnetron conveyor line 2 continues to convey the blanks, completing all the process steps of the magnetron end cap automatic assembly system of this embodiment.

[0034] Specifically, as a detection method, in this embodiment, the functional station includes a first functional station arranged between the loading station and the unloading station, and the functional component includes a lead detection component 8 corresponding to the first functional station, and the lead detection component 8 is used to detect the connection and disconnection of the lead of the magnetron 7; the lead detection component 8 of this embodiment includes a detection electrode and an electrode cylinder, and the detection electrode is connected to the detection power supply and driven by the electrode cylinder to move up and down. The detection electrode distinguishes between positive and negative poles. It is easy to understand that before the magnetron 7 is loaded, the lead direction of the magnetron 7 can be adjusted by rotation adjustment and other methods, so that the lead direction of the magnetron 7 after loading can match the direction of the detection electrode. In this way, when the magnetron 7 is rotated to the lowering of the detection electrode after loading, the electrode cylinder drives the detection electrode to move down and contact the positive and negative leads of the magnetron 7 to connect the detection power supply. After the detection, the control system software background marks the defective products so as to perform the subsequent distinguishing operation between qualified products and defective products.

[0035] In this embodiment, the functional station includes a second functional station arranged between the unloading station and the loading station, and the functional assembly includes a mold cleaning assembly 9 arranged corresponding to the second functional station, and the mold cleaning assembly 9 is used to clean the magnetron positioning mold 6. Referring to the accompanying drawings, the mold cleaning assembly 9 of this embodiment includes a shield, an air pipe and a shield cylinder, one end of the shield is connected to the air pipe and driven by the shield cylinder to move up and down. When the magnetron positioning mold 6 rotates with the multi-station turntable to the lowering of the mold cleaning assembly 9, the shield cylinder drives the shield to move down to cover the magnetron positioning mold 6, and then the negative pressure of the air pipe sucks away the debris that falls on the magnetron positioning mold 6, so as to ensure the cleanliness of the magnetron positioning mold 6 and the safe operation of the system.

[0036] As described above, after the magnetron 7 in this embodiment is inspected by the lead inspection component 8, the qualified magnetron 7 and the defective magnetron 7 in this process are obtained, which need to be processed separately. For this reason, preferably, as shown in the accompanying drawings, the magnetron conveying line 2 of this embodiment includes a qualified material channel, a defective material channel and an end push block component 10, the qualified material channel and the defective material channel are arranged side by side, and the end push block component 10 is arranged at the end of the qualified material channel and the defective material channel for pushing the magnetron 7 into the qualified material channel or the defective material channel. The end push block component 10 includes an open slider and a push plate; the open slider is movably arranged along the arrangement direction of the material channel and has an open cavity for placing the magnetron 7; the push plate is movably arranged along the feeding direction of the material channel. The magnetron 7 that passes the inspection will be pushed to the qualified material channel by the end push block component 10 for subsequent end cap assembly of this system, and the magnetron 7 that fails the inspection will be sent to the defective material channel for recycling.

[0037] As shown in the accompanying drawings, the qualified material channel of this embodiment includes an end cap assembly operation section and a magnetron unloading section, and the magnetron unloading section is provided with a unloading drive mechanism. In a preferred embodiment, a unloading detection sensor 11 is provided at the connecting end of the magnetron unloading section and the end cap assembly operation section, and the driving action of the unloading drive mechanism is controlled by the detection signal of the unloading detection sensor 11. During the feeding process of the magnetron 7 of the qualified material channel, when the unloading detection sensor 11 detects the feeding signal, the unloading drive mechanism is driven to operate, so that a certain gap is maintained between the end cap assembly operation section and the magnetron unloading section, thereby reducing the pushing resistance of the above-mentioned end push block assembly 10 and ensuring the accurate execution of the end cap assembly related actions.

[0038] See attached Figure 3As shown, the end cap feeding platform 3 is provided with a magnetron end cap vibrating feeding plate, and the magnetron end cap vibrating feeding plate includes a vibrating feeding plate 12, a spiral feeding channel 13 and a screening and sorting feeding channel, the spiral feeding channel 13 spirally rises from the bottom of the vibrating feeding plate 12 along the side wall of the vibrating feeding plate 12 to the upper part of the vibrating feeding plate 12, and the screening and sorting feeding channel is connected and arranged at the upper end of the spiral feeding channel 13; the screening and sorting feeding channel includes a single workpiece feeding channel 14, a flipping feeding channel 15, a first screening feeding channel 16, a second screening feeding channel 17 and a flipping and sorting feeding channel 18; the feeding channel width of the single workpiece feeding channel 14 is not greater than the maximum size of the magnetron end cap 701 and is connected to the discharge end of the spiral feeding channel 13; the flipping and sorting feeding channel The transfer feed channel 15 is connected to the lower part of the discharge end of the single workpiece feed channel 14 and forms a turning step with the single workpiece feed channel 14; the first screening feed channel 16 is connected to the discharge end of the flipping feed channel 15, and the first screening feed channel 16 is provided with a first screening blanking structure for performing a primary screening of the magnetron end caps 701; the second screening feed channel 17 is connected to the discharge end of the first screening feed channel 16, and the second screening feed channel 17 is provided with a second screening blanking structure for performing a secondary screening of the magnetron end caps 701; the flipping sorting feed channel 18 is connected to the discharge end of the second screening feed channel 17, and is used to turn and sort the magnetron end caps 701.

[0039] For details, see the attached Figure 4As shown, the magnetron end cap 701 of the present embodiment is generally in the shape of a cylindrical cover that is small at the top and large at the bottom, and its maximum size is the height of the magnetron end cap 701. A number of magnetron end caps 701 are poured into the vibrating material tray 12. Under the action of the vibration mechanism at the bottom of the vibrating material tray 12 continuously driving the vibration, the magnetron end caps 701 slowly rise along the spiral feeding channel 13. Since the width of the spiral feeding channel 13 is relatively wide, the rising rate of the magnetron end cap 701 can be guaranteed. However, the spiral feeding channel 13 lacks corresponding structural restrictions, resulting in different shapes of the rising magnetron end caps 701, such as forward, reverse, transverse, upright, inverted, parallel and stacked states, which need to be screened, adjusted and sorted through subsequent screening and sorting channels. First, the first structural screening is performed, that is, screening is performed through the single workpiece feeding channel 14 connected to the discharge end of the spiral feeding channel 13. Since the width of the single workpiece feeding channel 14 does not exceed the height of the magnetron end cap 701, only a single row of magnetron end caps 701 are allowed to move, so as to achieve the effect of screening and removing the magnetron end caps 701 moving side by side. Then, the second structural screening is performed, that is, screening is performed through the flipping feeding channel 15 connected to the discharge end of the single workpiece feeding channel 14. Through the setting of the flipping step at the connection between the single workpiece feeding channel 14 and the flipping feeding channel 15, there is a height difference between the two channels. According to the structural size characteristics of the magnetron end cap 701 of this embodiment, through the reasonable height setting of the flipping step, a flipping action can be performed after passing through the flipping step, and the state of the magnetron end cap 701 after flipping is improved to meet the next screening. Since the state of the magnetron end cap 701 when entering the single workpiece feeding channel 14 is uncertain, and there is also randomness when performing the flipping action through the flipping step, the state of the magnetron end cap 701 after flipping is not unique. At this time, the magnetron end cap 701 entering the first screening feeding channel 16 needs to be further screened. According to the structural size characteristics of the magnetron end cap 701, the magnetron end cap 701 that does not meet the sorting requirements can be screened out through the reasonable setting of the first screening blanking structure. After the previous several structural screenings, the magnetron end caps 701 that meet the sorting requirements can be basically screened out. In this embodiment, the second screening blanking structure of the second screening feeding channel 17 ensures that the magnetron end caps 701 enter the flipping sorting feeding channel 18 in the correct state for the most general adjustment and sorting, so that the magnetron end caps 701 are fed in a unified direction, which is convenient for the subsequent automatic assembly operation mechanism to perform the grabbing assembly action, and improves the assembly efficiency and assembly quality.

[0040] The above only describes the preferred embodiments of the present invention, but it cannot be understood as limiting the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. In short, all changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
