Definitions
- the invention relates to a system for the automated, hermetic sealing of housings, preferably metal housings, in which electronic components, in particular in an oxygen and steam-free atmosphere, are arranged, optionally with a welding chamber operated with nitrogen overpressure or underpressure, which has at least one with two to one another Movable electrodes trained welding head and corresponding feed and discharge devices for the housing to and from the welding head.
- Such systems are mainly used in the manufacture of electronic components.
- each of these drives also has disadvantages.
- the pneumatic drive is flexible in the opening travel and pressure setting, the opening and closing times are extremely long.
- the eccentric drive has a high closing speed, but is extremely inflexible in its movement.
- the object of the invention is to provide a system which avoids the disadvantages mentioned above and which also ensures a higher quality in production.
- a quality standard for such systems is that a hermetic sealing of the housing is possible, the interior of the housing should be absolutely free of oxygen and water vapor.
- the system according to the invention cited at the beginning is characterized in that the welding chamber can be evacuated and the welding head has at least one electrode which can be moved via a servo drive.
- the servo drive allows a high cycle frequency in the production line.
- the welding chamber is sealed and evacuated, with this evacuation being carried out in an average of 15 minutes. All atmospheric gases are extracted and then the welding chamber is filled with inert gas. The system is ready for operation again in no time.
- the welding chamber is connected to a gas drying circuit.
- This gas drying circuit essentially consists of two drying cartridges which contain a gas drying agent and each drying cartridge is connected separately to the welding chamber. A cartridge dries the inert gas from the welding chamber in operation. In the other cartridge, the moisture absorbed is extracted from the drying agent via vacuum and temperature. Through this alternating procedure, the operability of the system is always guaranteed.
- the welding space located in the welding head which surrounds the housing provided for welding, can be evacuated when the electrodes are closed. In order to obtain an even higher freedom from gas in the interior of the housing to be closed, evacuation is carried out shortly before welding in the welding head with the electrodes closed. Vacuum values of the order of 10 torr can be achieved.
- At least one electrode of the welding head has a channel for evacuation and a sealing ring for sealing off the second electrode.
- the procedure in the welding head is as follows: After inserting the housing into an electrode, the second electrode is closed until the O-ring seals. After a few seconds of evacuation, the electrodes are closed on the welding position. After the welding process, the electrodes are opened and the housing is removed using the ejector.
- the simple evacuation facility has resulted in a significant improvement in quality.
- the drying chamber is preceded by a drying oven and optionally a subsequent prechamber for the intermediate storage of the housing to be closed, the
- Entry opening into the welding chamber can be closed by a lock flap.
- the lock flap ensures that the welding chamber operates properly.
- the housings coming out of the drying oven must no longer come into contact with the environmental atmosphere. This means that housings that are delivered from the drying oven can also be used for service work in the
- Welding chamber are upstream. In addition, only the welding chamber has to be evacuated through the lock flap after the service work.
- an outlet lock chamber which can be both evacuated and flushed with inert gas, and the inlet and outlet openings of which each have a lock flap are reproduced in the welding chamber is lockable.
- the exit lock chamber 8 with its two lock flaps is of particular advantage.
- helium gas is added to the nitrogen for operating the welding chamber.
- This added helium gas is an indicator of the welding quality. If a housing leaks after the welding process, the gas flows out and is detected by a sensor.
- a quick method for quality control is preferably provided for random samples.
- the servo drive consists of an electronically controlled electric motor that drives a spindle, preferably a ball screw. This simple drive for closing and opening the electrode has proven its worth. Above all through the adjustability of the
- the electrode is preferably supported vertically by a spring assembly. This resilient
- the purpose of the support is that during the actual welding process, the flanging of the housing becomes practically zero, and the electrode has to be moved to a minimum in order to enable an optimal closure.
- the sealing necessary for the evacuation takes place on the rotating spindle part.
- Such a seal is to be carried out with conventional machine components, a high level of operational safety being guaranteed.
- FIG. 1 shows the schematic structure of the Complete system
- FIG. 2 the welding head with the servo drive
- FIG. 3 an evacuable electrode
- FIG. 4 the movement sequence during welding.
- the system for closing the metal housing consists of several chambers.
- the core of this system is the welding chamber 1, in which the welding head 2 is also arranged
- the welding chamber 1 Since electronic components are provided in the metal housings, these metal housings must be sealed in an atmosphere free of oxygen and water vapor. In order for this atmosphere to exist, the welding chamber 1 is operated in operation with a nitrogen overpressure, possibly also with a negative pressure.
- the welding head 2, which will be described later consists of electrodes that can be moved towards each other. Since these electrodes have to be serviced at regular intervals, the welding chamber 1 must be opened forcibly. In order to achieve a clean atmosphere in the welding chamber 1 for the welding after this maintenance work, the welding chamber 1 can be evacuated. The welding chamber is sealed tightly after the service or maintenance work and evacuated The atmospheric gases are extracted and then the welding chamber 1 is optionally filled with inert gas so that it is ready for operation again in the shortest possible time
- a drying oven 3 and a pre-chamber 4 are pre-built for the welding chamber 1.
- the welding chamber 1 also has an exit lock chamber 5. It is certainly extremely important with this system. that at least the openings of the welding chamber 1, i.e. the inlet opening from the pre-chamber 4 into the welding chamber 1 and also the opening from the welding chamber 1 into the outlet lock chamber 5, can be closed by means of lock flaps 6, 7.
- the connection opening from drying oven 3 to prechamber 4 is provided with a connecting lock 9
- the metal housings provided with the electronic components are dried in the drying oven 3, temporarily stored in the antechamber 4, sealed in the welding chamber 1 and discharged via the exit lock chamber 5.
- the welding chamber 1 is connected to a gas drying circuit.
- the welding head 2 has a servo drive 11 for moving the electrode 10.
- a servo drive 11 for moving the electrode 10.
- the housing 12 of the welding head 2 is a servo drive 11 for moving the electrode 10.
- the spindle 14 is provided with a spindle nut 16, which in turn moves the electrode 10 via at least two bolts 17.
- the bolts 17 have a suspension 19.
- the suspension 18 can also be a spring assembly
- the welding head 2 is closed shortly before the welding
- the metal housing 20 to be welded lies in a corresponding recess in the lower electrodes.
- the upper electrode 10a has a sealing ring 21 for sealing off the second electrode 10b. After the electrodes 10a, 10b have been closed and before welding, evacuation is carried out; this additional evacuation has brought about a clear improvement in quality.
- Diagram 4 the sequence of movements in the course of the welding process is shown over time.
- Diagram a shows the build-up of force during the welding process
- diagram b the spring travel of the suspension 18
- diagram c the movement of the electrode 10a
- diagram d the movement sequence of the servo drive
- diagram me the summation of the movement sequences or the speed of the overall system.
- the servo drive is started at maximum speed up to the first point of contact with the element to be welded. Shortly before reaching the touchdown point
- the electrode is returned to the starting position at maximum speed (diagram e position 34).
