[0027] like Figure 1 The device for laminating the sidewalls of electronic devices shown in the figure comprises a directionally extending transmission line 1, and a laminating unit 2 and a visual positioning unit 3 located on the side of the transmission line 1. A carrier 11 carrying the foam product to be laminated is placed on the transmission line 1, and the carrier 11 carries the product and moves between various workstations along the transmission line 1. The laminating unit 2 is used to attach foam to the side of the product and comprises a six-axis manipulator 21 located on the side of the transmission line 1 and a foam gripper 22 connected to the output end of the six-axis manipulator 21. The six-axis manipulator 21 grips the foam to be attached and moves it between the foam feeding mechanism and the transmission line 1. The visual positioning unit 3 is electrically connected to the control center and is used to accurately locate the placement of the foam. The positioning information is then transmitted to the six-axis manipulator 21, which then controls the six-axis manipulator 21 to laminate the foam.

[0028] like Figure 5 As shown, the transmission line 1 comprises two parallel linear rails 12. Multiple pulley transmission assemblies are arranged sequentially along the extension of the two linear rails 12. These pulley transmission assemblies divide the entire linear rail 12 into multiple transmission zones, each connected end to end. Each pulley transmission assembly includes a drive wheel 13 fixed to the side of the linear rail 12 and a conveyor belt 14 wound around the drive wheel 13. The drive wheel 13 is driven by a servo motor 15. By placing both sides of a carrier 11 on the surface of the conveyor belt 14 of the pulley transmission assembly, the carrier 11 can move along with the conveyor belt 14.

[0029] like Figure 2 and Figure 3 As shown, the number of bonding units 2 can be arbitrarily set according to the attachment position and number of the foam. Each bonding unit 2 includes a rotary motor 23 connected to the rotation output end of the six-axis manipulator 21, and the rotary motor 23 is perpendicular to the rotation direction of the rotation output end of the six-axis manipulator 21. The foam gripper 22 is connected to the output end of the rotary motor 23. The travel of the rotary motor 23 and the six-axis manipulator 21 are coordinated to achieve 360° free rotation of the foam gripper 22 to adjust the angle to achieve the most suitable bonding position. The foam gripper 22 of this embodiment is a U-shaped groove structure. The two ends of the U-shaped groove are provided with air holes 24 connected to the air source, which can quickly locate the position of the foam and adsorb the foam to the surface of the foam gripper 22 to prevent the foam from falling off during the transmission process. Furthermore, a calibration camera 27 is provided on the support arm of the six-axis manipulator 21 for locating the position of the foam gripper 22.

[0030] Furthermore, a slot-shaped photoelectric device 25 and a detection rod 26 provided between the slot-shaped photoelectric device 25 are provided on the side of the rotating motor 23. The detection rod 26 is connected to the rotating shaft of the rotating motor 23 and rotates synchronously with the rotating motor 23. When the detection rod 26 passes through the slot-shaped photoelectric device 25, the rotation position of the rotating motor 23 can be accurately identified.

[0031] like Figure 4 As shown, the visual positioning units 3 are arranged in multiple groups according to the location of foam attachment. Each group of visual positioning units 3 includes a fixed bracket 31 located on the side of the transmission streamline 1, a visual component and a linear light source 32 located on the fixed bracket 31. The visual component includes a CCD camera 33, a light guide arm 34 connected to the end of the CCD camera 33, and a prism 35 connected to the other end of the light guide arm 34. The deflection direction of the prism 35 can arbitrarily change the monitoring direction of the CCD camera 33, ultimately adjusting it to accurately monitor the position on the product surface to be attached, thereby saving space occupied by the visual positioning units 3. During the monitoring process, the linear light source 32 provides the necessary lighting conditions for the visual component.

[0032] In this embodiment, the bottom of the carrier 11 is provided with Figure 6 The lifting unit 4 shown is fixedly mounted between the linear rails 12 on both sides of each workstation via a connecting bracket 41. When the carrier 11 flows along the conveyor line 1 to each workstation, the lifting unit 4 can upwardly dock with the carrier 11, fixing the position of the product for the six-axis robot 21 to perform bonding.

[0033] Specifically, the lifting unit 4 includes a lifting cylinder 42 fixedly mounted on a connecting bracket 41, a lifting plate 43 being connected to the output shaft of the lifting cylinder 42, and a plurality of suction cups 44 being provided on the surface of the lifting plate 43, so that the suction cups 44 are connected to the air source, and a avoidance hole 16 for the suction cups 44 to pass through is provided at the bottom of the carrier 11. When the carrier 11 is in place, the lifting cylinder 42 will drive the lifting plate 43 to move upward, and it will be attached to the surface of the product through the avoidance hole 16, and the position of the product will be fixed by negative pressure adsorption. Furthermore, a positioning pin 45 is provided on the surface of the lifting plate 43, and a positioning hole 17 is provided on the carrier 11 at the position corresponding to the positioning pin 45. When the lifting cylinder 42 rises, the positioning pin 45 will extend into the positioning hole 17, completing the docking of the lifting plate 43 and the carrier 11.

[0034] Furthermore, the connecting bracket 41 is provided with a stopper 46 on the extended side of the lifting plate 43. The stopper 46 is connected to the output end of a vertically arranged stopper cylinder 47. When the stopper cylinder 47 is activated, the stopper 46 is lifted into the moving path of the carrier 11, so that the carrier 11 no longer moves along the transmission streamline 1. At this time, the lifting cylinder 42 drives the lifting plate 43 upward to complete the docking with the carrier 11.

[0035] Furthermore, the connecting bracket 41 is provided with a stopper 48 on the feed side of the lifting plate 43. This stopper 48 comprises a guide slope inclined along the direction of the transmission streamline 1, with the highest point of the guide slope being higher than the bottom plane of the carrier 11. As the carrier 11 moves along the transmission streamline 1, it follows the inclined surface of the stopper 48 and passes over the highest point of the stopper 48 to flow to the rear of the transmission streamline 1. When the carrier 11 passes through the stopper 48, the highest point of the stopper 48 blocks the carrier 11, preventing it from moving backward.

[0036] Furthermore, a code scanner 18 is provided on the side of the transmission streamline 1 for scanning the identification code on the surface of the carrier 11 to accurately determine the status of each carrier 11 .

[0037] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
