Description
[technical field]
The present invention relates to micro machine welding procedure field, relate in particular to a kind of stitch of welded disc turbine rotor commutator and pressure-sensitive welding procedure of needing.
[background technology]
The product that comes into operation now comprises automatic tin feeding wire mechanism, rotor feeding pressure mechanism, electric iron welding mechanism, rotor positioning rotating mechanism, in the process of welding, because welding commutator stitch temperature is higher than the temperature of pressure-sensitive of welding; So two steps will separately be accomplished, to the rotor commutator stitch be welded earlier, load onto pressure-sensitive then; Carry out once pressure-sensitive scolding tin again; Can not accomplish two welding step with a machine, need a machine to come scolding tin commutator stitch, two machines come pressure-sensitive of scolding tin; Twice scolding tin has increased the time and the workload of this procedure, and the consumption to tin is big simultaneously.
In the present processing step, at first rotor is installed in the rotor clamping rotatable parts of fixed rotor, gives target solder joint position tin feeding wire by automatic tin feeding wire mechanism when electric iron advances; Electric iron just can weld the stitch of commutator then, has welded after the stitch of commutator, and electric iron is return automatically; Correctly be placed on pressure-sensitive on the commutator, electric iron advances, and tin feeding wire mechanism gives target solder joint position tin feeding wire automatically; The commutator stitch that will weld then and pressure-sensitive welding are as an element solder step, in order to accomplish whole welding; Also need rotary rotor, repeat this process 2 times again.
[summary of the invention]
The present invention addresses the above problem a kind of shorter, consumption tin silk welding procedure still less in man-hour that consumes is provided.
The technical scheme that the present invention addresses the above problem is: said micro motor rotor commutator and pressure-sensitive soldering tin technique; Pressure-sensitive rotor at first will be housed packs in the rotor clamping rotatable parts; The electric iron welding mechanism drives the electric iron plumb joint and advances for the first time along worker thread, advances to the target solder joint position that needs welding, and tin feeding wire mechanism delivers to the tin silk target solder joint position that needs welding simultaneously; Scolding tin then; It is characterized in that: when scolding tin commutator and pressure-sensitive,, move at twice an operation the inside and to accomplish two place's scolding tin respectively with an electric iron plumb joint.
Two stages of a said operation are meant:
(1) the electric iron plumb joint advances to the commutator stitch for the first time; Spacing with the pressure-sensitive about 0.3-0.5mm of edge maintenance; The electric iron plumb joint presses down after tin feeding wire puts in place, and the electric iron plumb joint welds enamel-covered wire and commutator stitch admittedly, accomplishes the welding step to the commutator stitch;
(2) the electric iron plumb joint continues and continues reach on the basis of advancing for the first time, advances to pressure-sensitive silver coating edge or near the edge, just returns within pressure-sensitive silver coating 0.1-2s of electric iron plumb joint contact, promptly accomplishes pressure-sensitive welding action.
Said two stages: the phase I, let the electric iron plumb joint contact within pressure-sensitive silver coating 01.-2s earlier and shrink back; Second stage is retreated the 0.3-0.5mm distance, welding commutator stitch from pressure-sensitive.
In welding commutator stitch welds pressure-sensitive technology then, because the commutator stitch requires welding temperature high, and low this contradiction of pressure-sensitive welding temperature; So two welding processes can not merge; So having proposed and utilize the technical scheme of time difference to overcome this contradiction to this problem of this technology realizes that a process accomplishes twice technology, the temperature to the requirement of electric iron plumb joint reaches unanimity in technical process simultaneously; The setting-up time of electric iron plumb joint forehand weldig commutator first time stitch is more longer; And on the basis of the progressive position first time once more the time of pressure-sensitive of forehand weldig short, one touches and promptly recalls, so in pressure-sensitive of the welding; Though it is consistent that electricity irons the temperature of plumb joint; But because the time length of contact is consistent, the temperature of institute's contactant is also just inconsistent, to reach technological requirement.
When weldering commutator stitch and pressure-sensitive, the work of advancing of electric iron plumb joint, this process route section is divided into two working stages and goes to carry out pressure-sensitive of weldering commutator stitch.Pressure-sensitive has another name called the DV sheet, and this soldering tin technique is particularly suitable for micro machine face down bonding technology.
The invention has the beneficial effects as follows: the technology after the improvement is with electric iron welder forward travel distance, is divided into for two stages to carry out, and needs to divide before accomplishing with a process and call two machines; The welding process of dividing two steps to accomplish; Become simple rapidly, both satisfied welding stitch and pressure-sensitive technological requirement, simultaneously the operation simplify structure; Use manpower and material resources sparingly, save cost.

[specific embodiment]
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Improvement for welding procedure is characterized in that, with original electric iron welding mechanism 1, according to needed work operation demand; Be modified into moving of two the different distance advanced potentials that can make two bites at a cherry, because commutator stitch 7 is different with pressure-sensitive 6 position, and also different to the temperature requirement of welding; The standard welding temperature of commutator in scolding tin process in the past, can only be responsible for welding than pressure-sensitive 6 the high 200-300 of normal temperature ℃ by different scolding tin machines; Be divided into twice completion; At first, the rotor that is equipped with pressure-sensitive is packed in the rotor clamping rotatable parts, electric iron welding mechanism 1 drives electric iron plumb joint 2 and advances for the first time along worker thread; Advance to the target solder joint position that needs welding, tin feeding wire mechanism delivers to the tin silk target solder joint position that needs welding simultaneously; The improvements of technology are that the operating process that is divided into two stages comprises now:
1) the electric iron plumb joint advances to the commutator stitch for the first time; Spacing with pressure-sensitive edge maintenance 0.3-0.5mm; The electric iron plumb joint presses down after tin feeding wire puts in place, and electric iron plumb joint 2 welds enamel-covered wire and commutator stitch admittedly, accomplishes the welding step to commutator stitch 7;
2) electric iron plumb joint 2 continues and continues reach on the basis of advancing for the first time, advances to pressure-sensitive 6 silver coating edge or near the edge, just returns within pressure-sensitive 6 silver coating 0.1-2s of electric iron plumb joint 2 contacts, promptly accomplishes pressure-sensitive welding action.
The described welding process that is divided into two stages completion also can be to let the electric iron plumb joint contact within pressure-sensitive silver coating 01.-2s earlier shrink back; Second stage is retreated the 0.3-0.5mm distance, welding commutator stitch from pressure-sensitive.
Above step only is the welding of having accomplished a stitch, a unit step, and, accomplish the integral solder of a part through multiple operation.This soldering tin technique utilizes the time difference to realize that weldering commutator stitch temperature requirement is high; And weld the pressure-sensitive contradiction that temperature requirement is low; Simultaneously the temperature of electric iron plumb joint reaches unanimity, and the electric iron plumb joint setting of forehand weldig commutator stitch for the first time is more longer, and on the basis of the progressive position first time once more the time of pressure-sensitive of forehand weldig short; Though so the temperature of electric iron plumb joint is consistent; But because the time length of contact is consistent, the temperature of institute's contactant is also just consistent, to reach technological requirement.
When weldering commutator stitch and pressure-sensitive, the work of advancing of electric iron plumb joint, this process route section is divided into two working stages and goes to carry out pressure-sensitive of weldering commutator stitch.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within the protection domain of the utility model.
