If it is not centered, the position of the touchpad is adjusted by the center alignment adjustment component 27. If the touchpad is placed centered, the screw-locking mechanism 24 performs preliminary screwing; after the screwing is completed, the carrier is transported to directly above the height detection component 37 through the conveyor line 25 and is blocked by the blocking cylinder 26; then the height detection component 37 takes a photo to detect whether the touchpad is slightly lower than the upper surface of the keyboard tray. If the height does not meet the requirements, the screw-locking mechanism 24 adjusts the bolts on the touchpad. If the height meets the requirements, the carrier flows out.

[0033] Further, the screw-locking mechanism 24 includes two gantries 242 arranged in parallel on the machine table 21 and above the conveyor line 25, an XYZ-axis servo module 243 arranged on both sides of the two gantries 242 respectively, a screw gun 244 and a screw-locking positioning camera 245 respectively arranged at the driving ends of the XYZ-axis servo module 243, and a screw feeder 241 arranged on the machine table 21; the model of the screw gun 244 is Atlas M50, and a suction nozzle is arranged at the head; the screw-locking positioning camera 245 has 5 million pixels, a field of view of 15×15 mm, and a theoretical accuracy of 0.013 mm; during operation: the XYZ-axis servo module 243 drives the screw gun 244 and the screw-locking positioning camera 245 to move synchronously. First, the screw-locking positioning camera 245 takes a photo to determine the screw-locking position, then the suction nozzle at the head of the screw gun 244 sucks a screw from the screw feeder 241, and finally the screwing is performed.

[0034] Further, the conveyor line 25 is a double-layer double-speed chain, which can transport the carrier in a cycle, saving labor.

[0035] Furthermore, transparent protective covers 1 are provided for both the centering alignment screwing machine 2 and the height alignment screwing machine 3 to play a protective role, and connection ports 11 are provided at both ends of the conveyor line 25 for facilitating access to the production line of laptop computers.

At this time, the touch panel is located in the through hole 221, and at the same time, the positioning pins 278 on both sides of the upper end of the lifting frame 275 extend into the positioning holes of the carrier, which can effectively prevent the carrier from shifting during the screwing process; then the suction cup 277 sucks the touch panel; finally, the XY-axis alignment platform 272 drives the suction cup 277 to drive the touch panel to move horizontally until the touch panel is centered. During this period, the centering alignment detection component 23 will continuously take pictures to judge the position of the touch panel, and thus send a signal to the XY-axis alignment platform 272; when the height detection component 37 works: the lifting frame is lifted by the two lifting cylinders on both sides, and the carrier is abutted against the bottom of the positioning baffle 22. At this time, the touch panel is located in the through hole 221; at the same time, the positioning pins on both sides of the upper end of the lifting frame extend into the positioning holes of the carrier, which can effectively prevent the carrier from shifting during the screwing process; then the height detection camera 371 continuously takes pictures to compare the height of the touch panel and the keyboard tray, and thus sends a signal to the screwing mechanism.

[0037] Furthermore, the upper surface of the suction cup 277 is plated with silica gel, which can not only increase the friction force, effectively prevent the touch panel from shifting during the screwing process, but also play a role in protecting the surface of the touch panel.

[0038] Furthermore, a light source 279 is also provided on the outer circle of the suction cup 277 at the driving end of the XY-axis alignment platform 272. The backlight opening method is adopted to make the detection of the gap feature by the centering alignment detection component 23 more obvious.

[0039] Further, the centering alignment detection component 23 includes a support frame 231 disposed on the machine table 21 and above the screw locking mechanism 24, a support plate 234 disposed on the support frame 231, and a plurality of centering detection cameras 235 vertically disposed on the support plate 234 for determining whether the touch panel is centered; the centering detection camera 235 has 5 million pixels, a field of view of 30×30 mm, and a theoretical accuracy of 0.028 mm.

[0040] Further, a backing plate 232 is further disposed on the support frame 231; an adjustment hole 233 is disposed on the backing plate 232; the support plate 234 is disposed on the backing plate 232, and a plurality of centering detection cameras 235 all pass through the adjustment hole 233; long slots are respectively disposed on both sides of the support plate 234, and the support plate 234 is fixedly connected to the backing plate 232 by a plurality of bolts passing through the long slots; during operation, loosening the plurality of bolts can adjust the position of the support plate 234, thereby adjusting the positions of the plurality of centering detection cameras 235.

[0041] Further, weighing sensors 372 are further disposed on both sides of the height detection camera 371 of the height detection component 37. When the screw is overlocked, the weighing sensor 372 alarms to prevent damage to the product.
