DETAILED DESCRIPTION

[0052] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0053] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0054] like Figure 1-Figure 13 As shown, an embodiment of the present invention provides an unmanned automobile sun visor production line, including a fabric supply device 100, a shell supply device 200, a first feeding robot 300, a fabric heat sealing platform 400, a heat sealing robot 500, a transfer platform 600, a skeleton supply device 700, a second feeding robot 800, a hot riveting machine 900 and a finished workpiece conveying platform. The fabric supply device 100, the shell supply device 200, the fabric heat sealing platform 400 and the transfer platform 600 are arranged within the operating radius of the first feeding robot 300, and the transfer platform 600, the skeleton supply device 700, the hot riveting machine 900 and the finished workpiece conveying platform are arranged within the operating radius of the second feeding robot 800.

[0055] The fabric supply device 100 is used to supply fabric for the sun visor. Figure 2 A lifting feeding platform is provided on the fabric supply device 100, and a number of columns are provided around the lifting feeding platform to facilitate the positioning of the fabric on the X and Y axes. A screw motor structure is provided at the bottom of the lifting feeding platform to drive the lifting feeding platform to rise and fall on the Z axis. A laser sensor is installed on the top of the fabric to detect the Z-axis position of the fabric on the top of the fabric pile. After the first feeding robot 300 grabs the top layer of fabric, the Z-axis position of the top of the fabric will drop slightly, and the motor will drive the screw to rotate and lift the Z-axis position of the fabric, thereby automatically adjusting the height of the fabric pile to ensure a stable relative position between the top layer of the fabric pile and the first feeding robot 300.

[0056] The shell supply device 200 is used to supply the shell of the sun visor, and the shell includes a first half shell and a second half shell. The structure of the shell supply device 200 is similar to that of the fabric supply device 100, which will not be described in detail here.

[0057] The first loading robot 300 is used to transfer the fabric supplied by the fabric supply device 100 and the first half shell and the second half shell supplied by the shell supply device 200 to the fabric heat sealing platform 400, and to transfer the first half shell and the second half shell wrapped with the fabric on the fabric heat sealing platform 400 to the transfer platform 600.

[0058] The fabric heat-sealing platform 400 is used to cooperate with the first feeding robot 300 to wrap the fabric around the outside of the first half shell and the second half shell.

[0059] Reference Figure 3 , Figure 4 and Figure 5 The first feeding robot 300 includes a first robot arm 310, a first gripper frame 320 disposed at the free end of the first robot arm 310, and a fabric gripper and a pressing gripper 340 respectively disposed on both sides of the first gripper frame 320.

[0060] A heat-sealing mold 410 adapted to the first half shell and the second half shell is provided on the fabric heat-sealing platform 400 .

[0061] During the process of wrapping the fabric on the sun visor shell, the first loading robot 300 grabs the fabric from the fabric supply device 100 through the fabric gripper on one side of the first gripper frame 320, and grabs the first half shell and the second half shell from the shell supply device 200 through the pressing gripper 340 on the other side of the first gripper frame 320. Then the first loading robot 300 spreads the fabric grabbed by the fabric gripper in the heat-sealing mold 410 on the fabric heat-sealing platform 400, and then aligns the first half shell and the second half shell grabbed by the pressing gripper 340 with the heat-sealing mold 410 and places them on the fabric. The first loading robot 300 controls the pressing gripper 340 to press down the first half shell and the second half shell, so that the first half shell and the second half shell press the fabric into the groove of the heat-sealing mold 410. At this time, the edge of the fabric is flipped up and wrapped around the periphery of the first half shell and the second half shell.

[0062] The heat-sealing robot 500 is used to cooperate with the fabric heat-sealing platform 400 to heat-seal the edge of the fabric wrapped outside the first half shell and the second half shell with the periphery of the first half shell and the second half shell.

[0063] In some embodiments, the fabric gripper specifically includes four needle suction cups 330 respectively arranged at the four corners of the first gripper frame 320. The principle of the needle suction cup 330 grabbing the fabric is: the air pressure change in the chamber is controlled by the air inlet, so that the spring of the elastic component pushes the piston to move, thereby driving the needle body to extend or retract. When the needle body extends, it pierces the surface of the fabric, and the friction and mechanical bite between the needle and the fabric are used to grasp the fabric; when the fabric needs to be released, the needle body retracts, and the fabric can be separated from the suction cup.

[0064] The needle suction cup 330 can reliably grasp the covering material, and the four needle suction cups 330 evenly distributed at the four corners of the first gripper frame 320 can spread and flatten the fabric well.

[0065] In some embodiments, the pressing gripper 340 specifically includes two pressing frames 341 respectively adapted to the first half shell and the second half shell and a plurality of first vacuum suction cups 342 distributed in the two pressing frames 341. With such a design, the first half shell and the second half shell can be sucked by the first vacuum suction cups 342, and the sucked first half shell and the second half shell are respectively pressed against the corresponding pressing frames 341. In this way, when covering the fabric, the edges of the first half shell and the second half shell can be respectively pressed in the heat-sealing mold 410 by the two pressing frames 341 to ensure the covering quality.

[0066] Reference Figure 6 The heat sealing robot 500 includes a heat sealing robot arm 510 and a laser 520 disposed at the free end of the heat sealing robot arm 510, so that the laser 520 can be controlled by the heat sealing robot arm 510 to heat the part of the sun visor fabric that needs to be sewn, thereby realizing laser heat sealing between the fabric and the first half shell and the second half shell.

[0067] Preferably, a cylinder pressing block 420 is provided around the heat-sealing mold 410 for pressing the edge of the fabric positioned in the heat-sealing mold 410 around the first half shell and the second half shell. After the edge of the sun visor that needs to be heat-sealed is heated and melted, the fabric is pressed by the cylinder pressing block 420, and after the pressure is maintained and cooled, the edge of the fabric is heat-sealed to the corresponding edge of the sun visor shell.

[0068] The cylinders around the sun visor shell quickly heat-seal the fabric to the edge of the sun visor shell in a certain order. When the fabric is completely heat-sealed to the sun visor shell, the first loading robot 300 transports the sun visor covered with the fabric to the transfer platform 600. This method can improve the fabric covering efficiency of the sun visor shell. The whole process does not require manual operation, achieving unmanned production.

[0069] The transfer platform 600 is used to place the first half shell and the second half shell covered with fabric, referring to Figure 7The top surface of the transfer platform 600 is provided with a protruding rod for fixing the first half shell and the second half shell covered with fabrics. The transfer platform 600 is arranged at the center of the intersection of the operating radius of the first feeding robot arm and the second feeding robot arm, and is used for transfer between the fabric covering and hot riveting processing steps.

[0070] The skeleton supply device 700 is used to supply skeletons of sun visors. The skeleton supply device 700 can stack a certain number of sun visor skeletons at one time, and can cooperate with the second loading robot 800 to grasp and transport the sun visor skeletons.

[0071] The second loading robot 800 is used to load the skeleton supplied by the skeleton supply device 700 into the second half shell on the transfer platform 600, and after the skeleton is loaded into the second half shell, transfer the first half shell and the second half shell to the hot riveting machine 900, and transfer the sun visor processed by the hot riveting machine 900 to the finished workpiece conveying platform.

[0072] The hot riveting machine 900 is used to fold the first half shell and the second half shell to clamp the internal framework and perform hot riveting.

[0073] In some embodiments, reference Figure 8 and Fig. 9 The second loading robot 800 includes a second robot arm 810, a second gripper frame 820 arranged at the free end of the second robot arm 810, a skeleton gripper 830 and a shell gripper arranged on one side of the second gripper frame 820, and a sun visor gripper 850 arranged on the other side of the second gripper frame 820. The skeleton gripper 830 is used to grasp the skeleton, the shell gripper is used to grasp the first half shell and the second half shell, and the sun visor gripper 850 is used to grasp the processed sun visor.

[0074] Optionally, the skeleton gripper 830 adopts a parallel air claw gripper, and the shell gripper includes a plurality of second vacuum suction cups 840 arranged on both sides of the skeleton gripper 830 .

[0075] Optionally, the sun visor gripper 850 adopts a parallel air gripper, and rubber pads 851 are provided on the inner sides of the two jaws of the sun visor gripper 850. The rubber pads 851 can effectively avoid indentation and deformation of the side of the sun visor when the second mechanical gripper grasps the sun visor.

[0076] In this embodiment, the sun visor frame can be first picked up by the frame gripper 830 of the second feeding robot 800 and assembled into the second half shell of the sun visor, and then the assembled but unfinished first half shell and second half shell are grasped by the second vacuum suction cups 840 on both sides of the frame gripper 830 and transferred to the hot riveting machine 900 for processing. Before placing the unfinished automobile sun visor assembly, the second feeding robot 800 first assembles the last completed hot riveting assembly into the second half shell of the sun visor through the sun visor gripper 850 on the other side. The riveted automobile sun visor is taken away from the hot riveting machine 900, and then the gripper of the second loading robot 800 is rotated so that the first half shell and the second half shell are aligned with the hot riveting mold on the hot riveting machine 900, and then the first half shell and the second half shell that have not been hot riveted are placed in the hot riveting mold of the hot riveting machine 900 for hot riveting. Finally, the sun visor that has completed the hot riveting process is transferred to the finished workpiece conveying platform, and the sun visor that has completed the hot riveting process is transferred away when the second loading robot 800 loads next time.

[0077] This embodiment can completely replace manual assembly and transfer of sun visors, realize the function of multi-directional pick-up and placement of workpieces, can greatly improve processing efficiency, place and take materials simultaneously, optimize the layout, and reduce costs.

[0078] Reference Fig.11 In this embodiment, the hot riveting machine 900 is internally provided with a first hot riveting mold, a second hot riveting mold, a pressurizing mechanism and a heating lamp tube, each of which has a power of 1-3KW. After the second feeding robot 800 places the first half shell and the second half shell of the sun visor shell in the first hot riveting mold and the second hot riveting mold respectively, the first half shell, the second half shell and the skeleton pre-installed in the second half shell are first heated by the heating lamp tube to melt the part of the workpiece surface that needs hot riveting, and then the first hot riveting mold is controlled to flip and cover the second hot riveting mold, and the first hot riveting mold is pressed against the second hot riveting mold by the pressurizing mechanism, so that the two half shells and the sun visor skeleton are fully contacted and fused together in a molten state, and the first hot riveting mold is opened after a period of time to complete the hot riveting process of the sun visor.

[0079] In this embodiment, the first robotic arm 310 , the second robotic arm 810 , and the heat-sealing robotic arm 510 are all six-axis robotic arms.

[0083] Step S30, the first feeding robot 300 cooperates with the fabric heat-sealing platform 400 to wrap the edge of the fabric outside the first half shell and the second half shell and clamp them;

[0084] Step S40, the heat-sealing robot 500 cooperates with the fabric heat-sealing platform 400 to heat-seal the edge of the fabric with the periphery of the first half shell and the second half shell;

[0088] Step S80, the hot riveting machine 900 controls the first half shell and the second half shell to fold and clamp the internal framework and perform hot riveting;

[0089] In step S90, the second loading robot 800 takes out the processed sun visor from the laser hot riveting machine 900 and transfers it to the finished workpiece conveying platform.

[0090] The present application can use two manipulators to perform processes such as loading, heat sealing, unloading, transportation and hot riveting between the fabric supply device 100, the shell supply device 200, the fabric heat sealing platform 400, the transfer platform 600 and the hot riveting machine 900, thereby realizing unmanned production of sun visors, reducing labor costs, and by optimizing the process, achieving a balance between reducing the number of manipulators, shortening the average scheduling time of workpieces, and increasing production speed.
