The invention also discloses a method for the laser welding device of the engine control module, which comprises the following steps:
at first place control module 6 on the positioning seat of roating seat 1 through the workman, the rethread presses single start button, the controller will control driving motor 2a and carry out work, driving motor 2a will drive rotation axis 2b and rotate, it is rotatory through rotation axis 2b, rotation axis 2b will drive arc limiting plate 2d and rotate, make extension plate 2e and support strut 2f all rotate, support strut 2f will insert in slot 2c1, make support strut 2f promote driving plate 2c and rotate, driving plate 2c and then drive pivot 1b and rotate, arc limiting plate 2d and then card are gone into on arc spacing groove 2c2, lock dead the position of countershaft 1 b.
When the rotating shaft 2b rotates, the rotating shaft 2b drives the pushing ring 4h to rotate through the installation circular plate 4f, and when the pushing column 2f pushes the transmission plate 2c to rotate, the contact column 4j contacts with the flat bottom section 4h1, so that the control module 6 is not pushed to be inserted into the material guide frame 8.
After the transmission plate 2c is rotated, the contact column 4j is contacted with the bottom of the ascending section 4h2, through the continuous rotation of the installation circular plate 4f, the installation circular plate 4f pushes the contact column 4j to move upwards through the ascending section 4h2, so that the contact column 4j drives the ascending plate 4e to move upwards, when the contact column 4j is contacted with the deceleration section 4h5, the contact column 4j slowly ascends, and then the control module 6 is pushed to be inserted into the material guide frame 8, and the one-way clamping mechanism 3 is enabled to carry out limiting clamping on the control module 6, and the control module 6 cannot fall off from the inside of the material guide frame 8.
After the insertion is completed, the contact post 4j slides downwards along the downward sliding section 4h4 to make the magnet piece 4b descend, the control module 6 is clamped by the unidirectional clamping mechanism 3 to make the control module 6 not descend, and then the magnet piece 4b is separated from the control module 6, the contact post 4j slides downwards along the deceleration section 4h5 in a deceleration manner, the magnet piece 4b and the control module 6 slow down slowly to make the magnet piece 4b descend, the magnet piece 4b is separated from the control module 6, and then slides downwards quickly along the downward sliding section 4h4, when the contact post 4j moves to the bottom of the downward sliding section 4h4, the push-up plate 4e also descends together with the contact post 4j, so that the mounting tube 4c mounted on the push-up plate 4e drives the magnet piece 4b to descend, and the magnet piece 4b returns to the initial position, magnet piece 4b then realizes resetting, prepare for next promotion, and at this moment, push post 2f is in the position that fig. 9 located shows, push post 2f has not inserted in slot 2c1 yet, and then can not promote driving plate 2c and rotate, in this section distance of contact post 4j and flat bottom section 4h1 laminating motion (contact post 4j does not take place the motion, but flat bottom section 4h1 carries out rotary motion), because the rotation of push post 2f, will make push post 2f through screwing in slot 2c1, and then promote driving plate 2c and accomplish the rotation.
Compared with the prior art, the control module welding machine has the advantages that a manipulator is replaced by the first embodiment for taking down and placing products, so that the manufacturing cost is reduced, when the control module 6 is welded, a worker can place another control module without waiting aside, and the working efficiency of the worker is improved.
The push ring in the embodiment two drives the contact post 4j to move up and down, electric putter has been replaced and has been promoted, except can promoting the effect that control module inserted in the guide frame, in addition can also carry out automatic speed governing along with workman's work laying speed, avoid appearing the collision, because the workman lays control module speed occasionally very fast, sometimes slow, if adopt electric putter, when the workman lays too fast, when electric putter speed end has not been withdrawed, the roating seat just takes place rotatoryly, often can take place the collision between the two.
Through the speed reduction section 4h5 in the third embodiment, the speed reduction can be performed when the control module 6 is clamped with the one-way clamping mechanism, when the clamping is avoided, the one-way clamping mechanism 3 and the control module 6 are in violent collision to damage the control module, when the magnet piece 4b and the control module 6 are separated, the separation speed of the magnet piece 4b and the control module 6 is reduced, and the phenomenon that the bottom of the control module is pulled and sunken by the magnet piece 4b due to quick separation is avoided.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
