When the glass lifter welded component is clamped, the two ends of the glass lifter welded component can be located in the limiting grooves 138, thereby improving the stability of the clamping of the glass lifter welded component.

[0043] Working principle: During the use of the present invention, when the glass lifter welded parts are transported to the clamping mechanism 130, the transmission assembly drives the shift plate 134 and the shift plate 2 135 to approach each other, and then the elastic force of the spring 1 pushes the clamping plate 136 and the elastic force of the spring 2 to push the clamping plate 2 137 to approach each other, thereby clamping the glass lifter welded parts. When the shift plate 134 and the shift plate 2 135 approach each other, the inclined surface of the trigger block 151 at the bottom of the support rod 150 abuts against the top of the push column 144, thereby driving the support plate 141 to move downward, thereby driving the guide ring 160 to move downward, and then the gear 1 21 2 meshes with the tooth edge of the glass lifter weldment. When the glass lifter weldment is clamped, the transmission assembly continues to drive the shift plate 134 to move, and then drives the support rod 150 to move in the direction close to the guide ring 160.

The pull rope 174 pulls the pull plate 171 downward, and the spring 4 is in a stretched state. The tension sensor monitors the tension of the pull rope 174, so as to determine the tension of the pull rope 174 on the guide ring 160. The movement amount of the support rod 150 is different. The pulling force of the pull rope 174 is different, so that different pulling forces can be applied to the guide ring 160, so as to detect the welding strength of the glass lifter welded parts. When a certain pulling force is applied to the guide ring 160, the motor 214 drives the gear 1 212 to rotate, so as to drive the gear 1 212 to move along the tooth edge of the glass lifter welded parts. Therefore, the tooth edge of the glass lifter welded parts can be pulled in multiple directions, so as to comprehensively detect the welding strength of the glass lifter welded parts. When the support plate 141 moves downward, the piston 146 squeezes the liquid in the liquid storage cylinder 148, so as to The liquid is made to flow through the drain pipe 220, and the liquid squeezes the top head 221, and the top head 221 contacts the plate surface of the support plate 231, thereby driving the support plate 231 to move downward, and then driving the baffle plate 233 to move downward, and the through hole 234 on the plate surface of the baffle plate 233 coincides with the liquid inlet port of the drainage channel 240, and the lubricating oil in the gear 1 212 can be discharged through the drainage channel 240. When the gear 1 212 moves along the tooth edge of the glass lifter welded part, the tooth edge of the glass lifter welded part can be oiled, thereby reducing the friction during the movement of the lifter and increasing the service life of the glass lifter welded part.
