Automatic welding device for accessories for microwave oven magnetron electrode support

Abstract

The invention discloses an automatic accessory welding device for a magnetron electrode support of a microwave oven, in order to automatically weld a lead with a given length on one surface of the head of a flat electrode. The device comprises a head supply part (10), a lead supply part (20) and a spot welding part (30), wherein the head supply part (10) is provided with a feed hopper (12) which stores electrode heads (H) and an arrangement hopper (14) which arranges and supplies the heads (H); the lead supply part (20) comprises a material box (22) and a push rod (24), wherein the material box (22) discharges leads (L) one by one when the material box (22) stores the leads (L), the leads (l) discharged by the material box (22) are pushed to a lead accommodation electrode (33) as a welding position through the push rod (24), the leads (l) adhered with the heads (10) are separated from the lead accommodation electrode (33) after the welding; current is provided for the spot welding part (30) to weld under the state that the heads (H) supplied by the head supply part (10) and the leads (L) supplied by the lead supply part (20) are butted.

Description

technical field [0001] The invention is used for automatic welding of the head (end cover) and lead wire assembly used as a microwave oven magnetron electrode support accessory. In order to be able to automatically weld with the help of a spot welding machine while continuously supplying the head and lead wires, it includes: a head A part supply part, which has a supply hopper for accommodating the electrode head and an arrangement hopper for arranging and supplying the head; a lead wire supply part, which includes a magazine and a push rod, wherein the magazine stores the lead wire while , lead wires are discharged one by one, and the push rod pushes the lead wire discharged from the magazine to the lead wire containing electrode as the welding position, and after the welding is completed, the lead wire attached with the head is separated from the lead wire containing electrode; the spot welding part welding is performed by supplying current while the head supplied from the h...

Problems solved by technology

[0003] On the other hand, the head and the lead are joined together by resistance welding. In the past, the head and the lead were welded by a manual welding machine, so there was a problem of a decrease in productivity and an increase in manufacturing cost. At the same time, the welding quality was not uniform. , there is a disadvantage of high scrap rate due to poor welding
