[0036] Example

[0037] In order to solve the problem that the eyeshadow palette frame is manually glued and then manually hemmed in the prior art, which has low work efficiency, Figure 1 As shown, the present application discloses a double-jointed edging process for an eyeshadow palette frame, and the processing technology is realized by a leather shell edging machine, which includes a leather shell paper feeding mechanism 10, a glue coating machine 20, a transfer conveyor line 30, a gray board double-station feeding mechanism 40, a first transfer and grasping mechanism 50, a first edging mechanism 60, a second transfer and grasping mechanism 80, a connecting piece cutting mechanism 70, a third transfer and grasping mechanism 90, a second edging mechanism 100, a fourth transfer and grasping mechanism 110 and a feeding conveyor line 120, a leather shell paper feeding mechanism, a glue coating machine, a transfer conveyor line, a first edging mechanism, The connecting piece cutting mechanism and the second edge wrapping mechanism are arranged in sequence along the set direction, the shell paper feeding mechanism is arranged outside the gluing machine, the gray board double-station feeding mechanism is erected above the transfer conveyor line and extends outward, the first transfer and grabbing mechanism is erected above the negative pressure conveyor line and the first edge wrapping mechanism, the second transfer and grabbing mechanism is erected above the first edge wrapping mechanism and the connecting piece cutting mechanism, the third transfer and grabbing mechanism is erected above the connecting piece cutting mechanism and the second edge wrapping mechanism, and the fourth transfer and grabbing mechanism is erected above the second edge wrapping mechanism and the unloading conveyor line; the edge wrapping process includes the following steps (reference Figure 7 shown);

[0038] In the first step, the leather paper feeding mechanism will grab the two leather papers connected together by the connecting piece and put them into the gluing machine for gluing, and the glued leather papers will automatically fall on the transfer conveyor line;

[0039] In the second step, the gray board loading mechanism grabs two gray boards and places them on the two leather papers respectively, and the transfer conveyor line transports them to the end;

[0040] In the third step, the first transfer and grabbing mechanism grabs the two unwrapped gray boards into the first wrapping mechanism, and the front side, the rear side and the left side or the right side of the two leather papers are wrapped on the gray boards through the first wrapping mechanism;

[0041] In the fourth step, the second transfer and grabbing mechanism grabs the two gray boards that have been partially hemmed in the first hemming mechanism and puts them into the connecting piece cutting mechanism, and cuts off the connecting piece through the connecting piece cutting mechanism to separate the two leather papers;

[0042] Step 5: The third transfer and grabbing mechanism grabs the two gray boards that have been partially hemmed in the connecting piece cutting mechanism and puts them into the second hemming mechanism, and wraps the left or right sides of the two leather papers on the gray board through the second hemming mechanism;

[0043] In the sixth step, the fourth transfer and grabbing mechanism grabs the two gray boards that have completed the hemming in the second hemming mechanism and unloads them onto the unloading assembly line.

[0044] It should be noted here that the shell hemming machine in the present application also includes a shell paper palletizer A and two gray board palletizers B. In actual use, the shell paper feeding mechanism will grab two shell papers connected together by connecting plates from the shell paper palletizer and feed them to the gluing machine, while the double-station gray board feeding mechanism grabs two gray boards from the two gray board palletizers and puts them on the two shell papers so that they are pasted together with the two shell papers respectively.

[0045] refer to Figure 2As shown, the shell paper feeding mechanism of the present application includes two vertical blocks 11 arranged opposite to each other, a round rod 12 connected between the two vertical blocks, two connecting blocks 13 fixed on opposite sides of the round rod, two first lifting drive cylinders 14 arranged outside the two connecting blocks and connected to the two connecting blocks through connecting rods 15 respectively, a rotating shaft 16 rotatably connected between the two connecting blocks, a first reduction motor 17 arranged outside one of the connecting blocks and connected to the rotating shaft, and several first pneumatic suction heads 18 arranged on the rotating shaft. When the shell paper is fed, the two first lifting drive cylinders drive the two connecting blocks to rotate and descend so that the several first pneumatic suction heads suck a piece of two shell papers connected by a connecting piece from the shell paper palletizer. Then, the first reduction motor drives the rotating shaft to rotate so that the two shell papers connected by the connecting piece adsorbed by the several first pneumatic suction heads pass through the gluing machine (when the two shell papers extend into the gluing machine, the several first pneumatic suction heads will stop adsorbing the two shell papers), thereby realizing gluing.

[0046] refer to Figure 3 As shown, the present application is provided with a rolling mechanism 130 above the transfer conveyor line, and the rolling mechanism includes two second lifting drive cylinders 131 arranged on both sides of the transfer conveyor line in the non-conveying direction, a cross bar 132 connected to the piston rods of the two second lifting drive cylinders, and an attachment pressing wheel 133 mounted on the cross bar. Under normal operation, the two second lifting drive cylinders will drive the cross bar to descend to a set height and maintain a set distance with the transfer conveyor line. When the two gray boards are loaded and pass through the attachment pressing roller, the two gray boards will be attached to two leather shell papers.

[0047] refer to Figure 3 As shown, the present application also includes a fine-tuning correction mechanism 140, which includes an XY-axis moving platform 141 connected below the transfer conveyor line, a first truss 142 erected outside the XY-axis moving platform and making the crossbeam correspond to the transfer conveyor line, and a visual inspection camera 143 arranged below the crossbeam of the first truss. When the visual inspection camera detects that the positions of the two skins on the transfer conveyor line are different, the XY-axis moving platform will drive the transfer conveyor line to be fine-tuned along the XY-axis direction. This is to facilitate the first transfer mechanism to accurately grab the two skin papers into the first edge wrapping mechanism.

[0048] refer to Figure 4As shown, the gray board double-station feeding mechanism of the present application includes a second truss 41 erected outside the XY axis moving platform and having its crossbeam corresponding to the transfer conveyor line, an X-axis servo linear module 42 arranged in the length direction of the second truss crossbeam, two first lifting pneumatic slides 43 connected to the X-axis servo linear module, two first bottom plates 45 connected to the bottom of the two first lifting pneumatic slides through a plurality of first connecting columns 44, and a plurality of second pneumatic suction heads 46 respectively arranged at the bottom of the two first bottom plates. In the process of gray board feeding, the X-axis servo linear module drives Move the two first lifting pneumatic slides to the top of the two gray board stackers respectively, and then, the two first lifting pneumatic slides respectively drive several second pneumatic suction heads to descend to grab a gray board from the two gray board stackers (after grabbing the gray board, the two first lifting pneumatic slides drive several second pneumatic suction heads to reset), and then, the X-axis servo linear module drives the two first lifting pneumatic slides to the transfer conveyor line and correspond to the two leather shell papers. After they are in place, the two first lifting pneumatic slides will drive several second pneumatic suction heads to descend until the two gray boards are placed on the two leather shell papers.

[0049] In order to prevent the leather shell paper with gray board pasted on it from falling off the transfer conveyor line and preventing the first transfer and grabbing mechanism from realizing transfer and transportation, the present application provides a baffle 150 perpendicular to it at the conveying end of the transfer conveyor line, so that the leather shell paper with gray board pasted on it can be blocked by the baffle when it is transported to the end of the transfer conveyor line.

[0050] refer to Figure 5As shown, the transfer conveyor line, the first hemming mechanism, the connecting piece cutting mechanism, the second hemming mechanism and the opposite sides of the blanking assembly line of the present application are respectively provided with a third truss 160, and the two ends of the two third trusses are respectively provided with a lap block 170, and a lap plate 180 is overlapped between the two lap blocks; the first transfer and grabbing mechanism, the second transfer and grabbing mechanism, the third transfer and grabbing mechanism and the fourth transfer and grabbing mechanism have the same structure and respectively include a linear rack 52 arranged on the lap plate, a linear guide rail 51 arranged above the two third truss cross beams, a slide plate 54 sliding on the two linear guide rails, a second reduction motor 53 arranged above the slide plate and having an output shaft connected to a gear 531 that meshes with the linear rack; two support plates 55 arranged on one side of the slide plate, a second lifting pneumatic slide 56 arranged on the outside of the two support plates, two second bottom plates 58 connected to the bottom of the two second lifting pneumatic slides through a plurality of second connecting columns 57, and a plurality of third pneumatic suction heads 59 respectively arranged at the bottom of the two second bottom plates; in addition, the first transfer and grabbing mechanism The linear racks and linear guides included in the loading and grabbing mechanism, the second loading and grabbing mechanism, the third loading and grabbing mechanism and the fourth loading and grabbing mechanism are connected to each other; for example, when the first loading and grabbing mechanism of the present application is actuated, the corresponding second reduction motor drives the corresponding gear to rotate by cooperating with the linear rack so that the slide plate first moves to the top of the transfer conveyor line. After reaching the position, the two second lifting pneumatic slides will respectively drive the two second bottom plates to descend and when the several third pneumatic suction heads at the bottom of each second bottom plate contact the gray board, the gray board will be sucked (after which, the two second lifting pneumatic slides drive the two bottom plates to reset). Then, the corresponding second reduction motor drives the corresponding gear to rotate by cooperating with the linear rack so that the slide plate moves to the top of the first edge wrapping mechanism again. After reaching the position, the two second lifting pneumatic slides will respectively drive the two second bottom plates to descend. Finally, when the several third pneumatic suction heads stop adsorbing the gray board respectively, the two gray boards and the two leather shell papers at the bottom thereof will fall into the first glue wrapping mechanism.

[0051] The relevant principles of the second transfer and grasping mechanism, the third transfer and grasping mechanism and the fourth transfer and grasping mechanism are the same as those of the first transfer and grasping mechanism, and will not be repeated in this application.

[0052] The following content is for reference Figure 6As shown, the first edge-wrapping mechanism of the present application includes two first stands 61 and two first vacuum suction cups 62 arranged above the two first stands for adsorbing the non-edge-wrapped parts of the two shell papers. An edge-wrapping component a63 is respectively provided on the left and right sides of the first stand, and two edge-wrapping components b64 are respectively provided on the front and back sides of the first stand. The edge-wrapping component a and the edge-wrapping component b have the same structure and respectively include a first vertical plate 641, a third lifting drive cylinder 642 arranged on the first vertical plate, a first telescopic drive cylinder 643 connected to the piston rod of the third lifting drive cylinder, a first side pressure plate 644 connected to the first telescopic drive cylinder, a second telescopic drive cylinder 645 arranged on the first vertical plate above the first telescopic drive cylinder, a first mounting frame 646 connected to the piston rod of the second telescopic drive cylinder, and a first edge-wrapping pressure wheel 647 rotatably arranged in the first mounting frame.

[0053] When the first transfer and grasping mechanism respectively transports the two gray boards and the shell papers pasted on the bottom thereof and places them on the two first vacuum suction cups, the first telescopic drive cylinder included in each edge wrapping component a and each edge wrapping component b drives the first side pressure plate to extend to press the corresponding side edge of the shell paper to a vertical state; thereafter, the third lifting drive cylinder included in each edge wrapping component a and each edge wrapping component b drives the first telescopic drive cylinder to descend; finally, the second telescopic drive cylinder included in each edge wrapping component a and each edge wrapping component b drives the first edge wrapping pressure wheel to extend to press the corresponding side edge of the shell paper onto the gray board.

[0054] In one of the specific embodiments, the second edge-binding mechanism of the present application includes two second stands 101 and two second vacuum suction cups 102 respectively arranged above the two second stands for adsorbing the un-edge-binded parts of the two leather papers, and an edge-binding component c103 for edging the un-edged areas of the two gray boards is arranged between the two second vacuum suction cups. The edge-binding component c includes a second vertical plate 1031, a fourth lifting drive cylinder 1032 arranged in the second vertical plate, a first bidirectional drive cylinder 1033 penetrating the second vertical plate and connected to the piston rod of the fourth lifting drive cylinder, two second side pressure plates 1034 respectively connected to the two piston rods of the first bidirectional drive cylinder, a second bidirectional drive cylinder 1035 penetrating the second vertical plate of the first bidirectional drive cylinder, two second mounting frames 1036 respectively connected to the two piston rods of the second bidirectional drive cylinder, and two second edge-binding pressure wheels 1037 respectively rotatably arranged in the two second mounting frames.

[0055] When the gray board is edge-wrapped for the second time, when the third transfer and grabbing mechanism grabs the two gray boards on the connecting piece cutting mechanism to the two second vacuum suction cups respectively, the two first two-way driving cylinders drive the two second side pressure plates to extend and press the corresponding side edges of the shell paper to a vertical state. After that, the fourth lifting and driving cylinder drives the first two-way driving cylinder to descend. Finally, the second two-way driving cylinder drives the two second edge-wrapping pressing wheels to extend and press the corresponding side edges of the shell paper to wrap them on the gray board.

[0056] In one of the specific embodiments, the connecting piece cutting mechanism of the present application includes two third stands 71 ​​and two third vacuum suction cups 72 respectively arranged above the two third stands for adsorbing the unwrapped areas of the leather paper. A Y-axis servo linear module 73 is arranged between the two third vacuum suction cups, and a movable plate 74 is connected to the Y-axis servo linear module. Laser shears 75 are respectively arranged on the opposite sides of the movable plate. When the third transfer and grasping mechanism transports the two gray boards in the first edging mechanism and the leather paper pasted on the bottom thereof and places them on the two third vacuum suction cups respectively, the Y-axis servo linear module drives the movable plate to move from one side of the connecting piece. At the same time, starting the laser cutter can cut the connecting piece from the opposite sides of the connecting piece. In this way, the two leather papers can be separated, which is convenient for continuing to edging the remaining side of the gray board in the later stage.

[0057] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable technicians familiar with the technical field to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
