Use principle:

It is welded and fixed on plate 21 in use, being manually placed in first sensor, starts two clamping cylinders 27, so that two Collet 26 clamps sensor both ends, then controls the contraction of 24 piston rod of the second lifting cylinder, so that plate 21 and sensing is welded and fixed Device is detached from, and starts rotary electric machine 25, and rotary electric machine 25 drives sensor rotation, starts laser-welding machine 4, and laser-welding machine 4 is sent out Raw laser and the welding position for irradiating sensor, complete welding processing.

After completion, the piston rod of the second lifting cylinder 24, which extends, to be resetted, and sensor is contacted with plate 21 is welded and fixed, and is clamped The piston rod of cylinder 27 is shunk, and sensor and collet 26 disengage.

Start the first lifting cylinder, extend the piston rod of the first lifting cylinder, drive the decline of clamping element height, so that weldering Two clamping pieces 71 for connecing 21 top of fixed plate are located at sensor both ends, start gripper cylinder 72, so that the piston of gripper cylinder 72 Bar is shunk, and two clamping pieces 71 clamp sensor, and the piston rod of the first lifting cylinder, which is shunk, drives clamping piece 7 and sensor to rise, After hit the ceiling, sliding cylinder 93 pushes sliding block 92 to slide along sliding rail 91, so that the clamping piece 7 is moved to mark and consolidates 31 top of fixed board, then the piston rod elongation of the first lifting cylinder drives clamping piece 7 and sensor decline, and sensor, which is placed in, to be beaten It marks in fixing groove 32, then the piston rod elongation of the gripper cylinder 72 on the clamping piece 7, decontrols sensor, i.e. completion sensor The feeding of fixed device 3 from weld fixture apparatus 2 to mark.

Then mark is carried out.When mark, start limiting cylinder 35, extend the piston rod of limiting cylinder 35, drives limit Plate 36 pushes sensor towards one end of limit plate 36, so that the sensor other end is against on laser marker 5, starting laser is beaten Device 5 is marked, mark work is completed.

While mark, the piston rod of the first lifting cylinder, which rises, drives clamping piece 7 to rise, sliding cylinder 93 shrink with So that the clamping piece 7 resets.And in the process second sensor is placed in be welded and fixed on plate 21 and carries out welding processing.

After mark completion, limiting cylinder 35 drives limit plate 36 to reset.

After the welding processing of second sensor and the mark processing of first sensor are all completed, the first lifting air The piston rod of cylinder extends again, so that two clamping pieces 7 decline together, declines positioned at the clamping piece 7 being welded and fixed above plate 21 Second sensor is clamped, decline first sensor of clamping of clamping piece 7 above mark fixed plate 31.

Then the piston rod of the first lifting cylinder is shunk again, is lifted two sensors, is lifted to after maximum height, sliding The piston rod elongation of cylinder 93 is moved, so that second sensor is located at 31 top of mark fixed plate, then utilizes the first lifting air The piston rod of cylinder extends, and by second sensor strip to mark fixed plate 31, the piston rod of gripper cylinder 72 extends, by second A sensor is placed in mark fixed plate 31, and then the first lifting cylinder piston rod retracts, and 35 piston rod of limiting cylinder stretches out, Mark processing will be carried out on second sensor top to laser marker.First sensor completes the blankers after mark simultaneously Make.Such cycle operation.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
