いという問題を生じていた。Problems to be Solved by the Invention However, with such conventional equipment, when attempting to weld the lead wires after impregnating the capacitor element body with a thermoplastic impregnating agent such as wax, the impregnating agent that has already been impregnated is removed. It melts due to the heat generated during welding and adheres to the tip of the welding electrode. The impregnating agent attached to the tip of the welding electrode becomes an insulator, making it difficult for current to flow between the welding electrodes.As a result, sufficient heat cannot be obtained, resulting in a decrease in the welding strength of the lead wire, and the welding becomes unstable. The problem was that it did not change.

溶接強度が安定しないという現象の生じることが
明らかになつた。 In addition, with this device, if you try to weld the lead wire when the welding electrode is cold, such as when the welding equipment starts operating, some of the joule heat will be generated at the current value during normal operation because the welding electrode is cold. The amount of heat is taken away to heat the welding electrode, melting a portion of the lead wire and the metallicon part, and making it impossible to obtain the amount of heat necessary to weld the lead wire. For this reason, measures such as increasing the current setting value are taken immediately after the welding equipment starts operating. However, after the welding electrode is heated due to continuous operation, if the current setting is kept at a high value, more heat will be generated than necessary, and if welding is continued, the welding condition will deteriorate. Therefore, it is necessary to lower the current setting value as the welding electrode heats up, which significantly deteriorates workability and causes the phenomenon that the welding strength of the lead wire is unstable immediately after the welding equipment starts operating. has become clear.

される。With this configuration, even if a thermoplastic impregnant such as wax adheres to the tip of the welding electrode and solidifies, the solidified impregnant can be melted and blown away by jetting high-temperature air. Since it is possible to always keep the tip of the welding electrode free of impregnating agent, the welding strength of the lead wire is improved and its variation is reduced.
In addition, even when the welding electrode is cold immediately after the welding equipment starts operating, high-temperature air is injected into the welding electrode, so the welding electrode can be rapidly heated, which reduces the welding strength of the lead wire immediately after the welding equipment starts operating. Stabilization is achieved.

る。 In this way, the impregnating agent adhering to the tip portions of the welding electrodes 6a, 6b is melted and blown away by the high temperature air jetted from the nozzles 2a, 2b. Therefore, the impregnating agent can be easily removed, and the tips of the welding electrodes 6a, 6b can always be kept free of the impregnating agent.
This stabilizes the current during each weld and stabilizes the amount of heat generated, improving the welding strength of the lead wire by approximately 1.5 times as shown in Figure 2. In addition, since the welding electrode can be rapidly heated immediately after the welding equipment starts operating, a stable amount of heat can be obtained, so the welding strength of the lead wire immediately after the welding equipment starts operating is also the third level.
As shown in the figure, stabilization can be achieved and the reliability of the film capacitor can be further improved.
