[0051] When the welding is completed, the moving rail 4 drives the finished product to move to above the recycling box 6, and the moving rail 4 drives the finished product to swing, since the electronic component is welded on the to-be-welded bottom plate 2, if the welding is not firm enough, the electronic component will fall off in the swinging process, and thus fall into the recycling box 6, since the to-be-welded bottom plate 2 is flat, the laser range finder 15 at the end of the adsorption plate 14 emits measurement laser, when the electronic component falls off, the measured value will change, so that whether the electronic component on the to-be-welded bottom plate 2 is separated or not is known; after the separation is found, the to-be-welded bottom plate 2 is directly put into another recycling box 6, and through the detection arrangement, the defective products such as false welding can be effectively reduced;

[0052] The notch groove is arranged to be higher than the adsorption plate 14, so that when the adsorption plate 14 is attached to the to-be-welded bottom plate 2, the optical camera 13 still keeps a distance from the conveying belt 1, and damage is reduced;

[0053] The electromagnet is powered to generate magnetic force, so as to adsorb the to-be-welded bottom plate 2, and then the to-be-welded bottom plate 2 is grabbed and transferred, when the to-be-welded bottom plate 2 is not a metal material that can be magnetized, the vacuum pump generates suction force, which is transmitted to the adsorption hole 19 through the transmission pipe 16, so as to grab the to-be-welded bottom plate 2, and thus the function of grabbing to-be-welded bottom plates 2 of various materials is realized;

[0054] When the to-be-welded bottom plate 2 is adsorbed at the bottom of the adsorption plate 14, the electric wheel 22 is started to rotate, and the elliptical electric wheel 22 can periodically rub the to-be-welded bottom plate 2, so as to drag the to-be-welded bottom plate 2 to the direction of the connecting table 17, so as to make one edge of the to-be-welded bottom plate 2 abut against the abutting bar 18, so as to further position the to-be-welded bottom plate 2, so that the abutting accuracy in the abutting process with the electronic element can be ensured, and the welding quality can be ensured, and the abutting bar 18 can be replaced, and different abutting bars 18 can be adapted to different shapes of the to-be-welded bottom plate 2.

[0055] The abutting bar 18 is arranged to abut against the to-be-welded bottom plate 2, so as to further position the to-be-welded bottom plate 2.

[0056] The three electric sliding rails are connected in pairs, so as to realize the arbitrary movement of the grabbing table 3 in space, one grabbing table 3 waits for the to-be-welded bottom plate 2, and the other grabbing table 3 performs the welding operation, and the two grabbing tables 3 work alternately, so as to improve the work efficiency, and the laser range finder 15 can detect the distance between the two grabbing tables 3 in real time, so as to ensure that the two grabbing tables 3 do not affect each other.

[0057] The obliquely arranged welding gun 21 can make the welding wire more conveniently contact the abutting position of the to-be-welded bottom plate 2 and the electronic element, and the electric telescopic rod 20 can control the movement of the welding gun 21, so that the welding wire of the welding gun 21 abuts against the to-be-welded bottom plate 2 and the electronic element after the to-be-welded bottom plate 2 and the electronic element are abutted, and the mutual influence between the parts is reduced.

[0058] The electric telescopic rod 8 is shortened to control the rising of the mechanical claw 9, so as to obtain the electronic element from above, the electronic element is sent to the mechanical claw 9 by using a conveying device, and then the mechanical claw 9 drives the electronic element to sink and abut against the top surface of the to-be-welded bottom plate 2 to wait for welding, the welding process starts the air extractor, absorbs the smoke generated during welding, and transfers the smoke to the outside through the exhaust pipe 23, so as to maintain a healthy welding environment.

It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
