[0053] As Figure 1 - Figure 2 shown, this embodiment provides a cell phone copper VC upper and lower cover closing and welding device, which includes a workbench 100. The workbench 100 is rotatably provided with a turntable 10, and the turntable 10 is provided with at least one assembly fixture 11.

[0054] In some embodiments, to avoid an idle period, there are at least three assembly fixtures 11 on the turntable 10, that is, the number of assembly fixtures 11 can be three, four, five, six or more. When there are three assembly fixtures 11, the adjacent two assembly fixtures 11 are arranged at 120° with respect to the center of the turntable 10; when there are four assembly fixtures 11, the adjacent two assembly fixtures 11 are arranged at 90° with respect to the center of the turntable 10; when there are five assembly fixtures 11, the adjacent two assembly fixtures 11 are arranged at 72° with respect to the center of the turntable 10; when there are six assembly fixtures 11, the adjacent two assembly fixtures 11 are arranged at 60° with respect to the center of the turntable 10, and so on.

[0055] In some embodiments, the workbench 100 is provided with a lower cover feeding module 20, an upper cover feeding module 50 and a closing cover resistance welding module 70 around the turntable 10; wherein, the lower cover feeding module 20 is used to convey the lower cover to the assembly fixture 11, the upper cover feeding module 50 is used to convey the upper cover to the assembly fixture 11 and pre-assemble it with the lower cover, and the closing cover resistance welding module 70 is used to spot-weld the pre-assembled upper cover and lower cover; the workbench 100 is also provided with a lower cover feeding vision module 30 and an upper cover feeding vision module 60, and the lower cover feeding vision module 30 and the upper cover feeding vision module 60 are respectively used for visual positioning of the lower cover and the upper cover.

[0056] In this way, when the turntable 10 rotates, it can drive the assembly jig 11 to automatically rotate to the next position. Specifically, the lower cover feeding module 20 first conveys the lower cover to the lower cover feeding vision module 30 for vision positioning. After taking a picture for positioning and giving the coordinates, the lower cover is then placed on the assembly jig 11 of the turntable 10 by the lower cover feeding module 20. The turntable 10 rotates to rotate the assembly jig 11 with the lower cover to the next station. At this time, the upper cover feeding module 50 grabs the upper cover and conveys it to the upper cover feeding vision module 60 for vision positioning. After taking a picture for positioning and giving the coordinates, the upper cover is then placed in the assembly jig 11 containing the lower cover by the upper cover feeding module 50, so that the lower cover and the upper cover are pre-assembled. Finally, the assembly jig 11 continues to rotate to the next station, and the lower cover and the upper cover that are pre-assembled are spot-welded by the cover closing resistance welding module 70, thus completing the process of closing the upper cover and the lower cover.

[0057] In some embodiments, the lower cover is sucked by a manipulator to move the product to the camera photographing position. After taking a picture for positioning and giving the coordinates, it is placed in the jig. The upper cover is sucked by a manipulator to move the product to the camera photographing position. After taking a picture for positioning and giving the coordinates, it is placed in the jig to achieve fitting.

[0058] Adopting the above embodiments can replace manual labor to achieve the closing and welding of the upper and lower covers, reduce the labor intensity of workers, save manpower, and improve efficiency. Moreover, vision positioning helps to ensure the consistency of product assembly and the quality of assembled products.

[0059] In some embodiments, as Figure 3 shown, the lower cover feeding vision module 30 includes a light-transmitting plate 31, a lens 34 and a vision camera 35. The light-transmitting plate 31 is embedded in the workbench 100, and the light-transmitting plate 31 is provided with a detection hole 32. The lens 34 is placed inside the workbench 100 and is arranged corresponding to the detection hole 32. The vision camera 35 is connected to the lens 34. Conducting vision positioning on the lower cover through the vision camera 35 and the lens 34 helps to ensure the consistency of subsequent product assembly and the quality of assembled products.

[0060] In some embodiments, to improve the accuracy of vision positioning, for this reason, the lower cover feeding vision module 30 further includes at least one side plate 33. At least one side plate 33 is arranged at the side end of the light-transmitting plate 31, and the side plate 33 is provided with a light source (not shown). The light source can enhance the light source supplement of the lower cover through the light-transmitting plate 31, so that the vision camera 35 can obtain a more accurate vision image, thereby improving the positioning accuracy.

[0061] In other embodiments, the principle and structural design of the upper cover feeding vision module 60 are the same as or similar to those of the lower cover feeding vision module 30, and will not be repeated here.

[0062] In some embodiments, as Figure 6As shown in the figure, the upper cover loading module 50 includes an X-axis linear module 51, a Y-axis linear module 52, a Z-axis linear module 53, and a rotary suction cup 54. The X-axis linear module 51 is installed on the workbench 100. The Y-axis linear module 52 is connected to the X-axis linear module 51. The Z-axis linear module 53 is connected to the Y-axis linear module 52. The rotary suction cup 54 is connected to the Z-axis linear module 53. Through the X-axis linear module 51, the Y-axis linear module 52, the Z-axis linear module 53, and the rotary suction cup 54, the upper cover loading module 50 can move in multiple directions and perform visual positioning adjustment, can replace manual labor to achieve automatic loading, reduce the labor intensity of workers, save manpower, and improve efficiency.

[0063] In other embodiments, the qualified lower covers are conveyed from the conveyor belt of the previous machine. The lower cover loading module 20 is connected to the conveyor belt of the previous machine, so as to transfer the qualified lower covers on the conveyor belt to the assembly jig 11. It should be noted that the principle and structure of the lower cover loading module 20 are the same as or similar to those of the upper cover loading module 50, and will not be repeated here.

[0064] In other embodiments, the lower cover loading module 20 and the upper cover loading module 50 can also be replaced by a multi-axis robot, and the multi-axis robot can achieve the same functions and effects.

[0065] In some embodiments, as Figure 4 and Figure 5 shown, the mobile phone copper VC upper and lower cover closing and welding device further includes an upper cover lifting module 40. The upper cover lifting module 40 is used for stacking and storing upper covers. The rotary suction cup 54 of the upper cover loading module 50 can move to the upper cover lifting module 40 to grab the upper cover and convey it to the assembly jig 11 for pre-assembly with the lower cover.

[0066] In the above embodiments, the upper cover lifting module 40 includes a first bracket 41, a profiling positioning bar 43, a limiting rod 45, and a lifting motor 46. Among them, the first bracket 41 is movably provided with a lifting plate 42. The lifting plate 42 is used to support the upper cover. After the upper covers are stacked, they are placed on the lifting plate 42, so that the upper cover loading module 50 can achieve uninterrupted material taking and loading. The lifting motor 46 is arranged on the first bracket 41. The lifting motor 46 is connected to the lifting plate 42. The lifting motor 46 can drive the lifting plate 42 to rise or fall, so as to facilitate the upper cover loading module 50 to take materials.

[0067] In the above-described embodiment, the profiling positioning bar 43 is vertically disposed on the first bracket 41, and the profiling positioning bar 43 is perpendicular to the plane where the lifting plate 42 is located. The profiling positioning bar 43 is used to position the head of the upper cover to prevent the upper cover from shifting and affecting the grasping accuracy of the rotary suction cup 54. The limiting rods 45 are connected to the first bracket 41 and are disposed on opposite sides of the first bracket 41. The limiting rods 45 are used to limit the left and right sides of the upper cover. The limiting rods 45 cooperate with the profiling positioning bar 43 to achieve multi-point limiting of the upper cover.

[0068] In some embodiments, to meet the compatibility requirements of upper covers of different models, the upper cover lifting module 40 further includes an adjustment block 47 disposed on the first bracket 41. The adjustment block 47 is provided with a plurality of adjustment holes, and the limiting rods 45 are connected to the adjustment holes. By connecting the limiting rods 45 to different adjustment holes, the distance between two opposite limiting rods 45 can be controlled to match the limiting of upper covers of different models.

[0069] In some embodiments, to ensure the position accuracy of the upper cover before feeding, the upper cover lifting module 40 further includes an adjustment cylinder 44. The adjustment cylinder 44 is connected to the first bracket 41 and is disposed on opposite sides of the lifting plate 42. The adjustment cylinder 44 is used to adjust and limit the upper cover on the lifting plate 42. By providing opposite adjustment cylinders 44, the position of the upper cover placed on the lifting plate 42 can be corrected, thereby ensuring the grasping accuracy of the rotary suction cup 54 and further improving the accuracy after the upper cover and the lower cover are closed.

[0070] In some embodiments, as Figure 7 and Figure 8 shown, the cover closing and resistance welding module 70 includes a second bracket 71. The second bracket 71 is provided with a first cylinder 72 and a second cylinder 74. The piston end of the first cylinder 72 is provided with a lower electrode 73, and the piston end of the second cylinder 74 is provided with an upper electrode 75. The lower electrode 73 and the upper electrode 75 are disposed opposite to each other. When the pre-assembled upper cover and lower cover rotate to the welding station along with the assembly jig 11, the first cylinder 72 drives the lower electrode 73 to rise and abut against the lower cover, and the second cylinder 74 drives the upper electrode 75 to descend and abut against the upper cover, thereby realizing spot welding of the lower cover and the upper cover when the lower electrode 73 and the upper electrode 75 are working.

[0071] In some embodiments, to avoid the occurrence of defective products due to relative displacement between the lower cover and the upper cover during the spot welding process, the cover closing resistance welding module 70 further includes a pressure feeding assembly 76. The pressure feeding assembly 76 includes a pressure feeding cylinder 761, a support plate 762, a pressure plate 763, and an elastic member 765. The pressure feeding cylinder 761 is connected to the second bracket 71, and the pressure feeding cylinder 761 and the second cylinder 74 are disposed at the same end of the second bracket 71. The support plate 762 is provided at the piston end of the pressure feeding cylinder 761. The pressure plate 763 is provided with a limit post 764, and the limit post 764 is movably and limitedly connected to the support plate 762. The elastic member 765 is sleeved on the limit post 764, and the elastic member 765 is disposed between the pressure plate 763 and the support plate 762. In this way, before welding, the pressure plate 763 first abuts against the upper cover, so that no relative displacement can occur between the upper cover and the lower cover, and then spot welding is performed to ensure the quality of spot welding. During this process, to avoid mechanical friction between the pressure plate 763 and the upper cover, the pressure plate 763 is movably and limitedly connected to the support plate 762 through the limit post 764, and an elastic member 765 is provided between the pressure plate 763 and the support plate 762. The elastic member 765 provides a pre-tightening force to the pressure plate 763, thereby playing a role in protecting the upper cover.

[0072] In other embodiments, the elastic member 765 is preferably a spring.

[0073] As Figure 1 and Figure 2 shown, when the upper cover and the lower cover are spot welded by the cover closing resistance welding module 70 at the welding station, for the convenience of product transfer and conveying, the cover closing welding device for the upper and lower covers of the mobile phone copper VC further includes a blanking transfer module 80 and an output conveyor belt 90. The blanking transfer module 80 and the output conveyor belt 90 are both disposed on the workbench 100. The blanking transfer module 80 is used to transfer the product welded by the cover closing resistance welding module 70 to the output conveyor belt 90, and the output conveyor belt 90 is used to convey the welded product to the next process.

[0074] The working process of the present utility model is as follows: Please refer to Figure 1 - Figure 8 . When in use, the lower cover loading module 20 takes materials from the OK product conveyor belt of the previous machine, after the lower cover is visually positioned by the lower cover loading vision module 30, it is placed into the assembly fixture 11. The assembly fixture 11 rotates with the turntable 10 to the upper cover loading station. The upper cover loading module 50 grabs the upper cover from the upper cover lifting module 40. After the upper cover is visually positioned by the upper cover loading vision module 60, it is placed into the assembly fixture 11 containing the lower cover to complete pre-assembly. The assembly fixture 11 continues to rotate with the turntable 10 to the upper and lower cover closing and welding station, and the cover closing resistance welding module 70 spot welds the pre-assembled upper cover and lower cover. The welded product is transferred to the output conveyor belt 90 for blanking through the blanking transfer module 80. The assembly fixture 11 continues to rotate to the lower cover loading station to wait for loading, and so on in a cycle.

[0075] In summary, the embodiment of the present utility model provides a cover closing and welding device for the upper and lower copper VC of a mobile phone. By setting a turntable 10 on the workbench 100 and an assembly fixture 11 on the turntable 10, when the turntable 10 rotates, it can drive the assembly fixture 11 to automatically rotate to the next position. Specifically, the lower cover feeding module 20 first conveys the lower cover to the lower cover feeding vision module 30 for vision positioning. After positioning, the lower cover feeding module 20 places the lower cover on the assembly fixture 11 of the turntable 10. The turntable 10 rotates to rotate the assembly fixture 11 with the lower cover to the next working station. At this time, the upper cover feeding module 50 grabs the upper cover and conveys it to the upper cover feeding vision module 60 for vision positioning. After positioning, the upper cover feeding module 50 places the upper cover in the assembly fixture 11 equipped with the lower cover, so that the lower cover and the upper cover are pre-assembled. Finally, the assembly fixture 11 continues to rotate to the next working station, and the cover closing resistance welding module 70 spot-welds the pre-assembled lower cover and upper cover, thus completing the cover closing process of the upper cover and the lower cover. The present utility model can replace manual labor to achieve the cover closing and welding of the upper and lower covers, reduce the labor intensity of workers, save manpower, and improve efficiency. Moreover, vision positioning helps to ensure the consistency of product assembly and the quality of assembled products.
