[0040] In the following embodiments, unless otherwise specified, the functional components or structures are conventional components or structures used in the art to achieve the corresponding functions.
[0041] Example 1:
[0042] like Figures 1-8 The image shows an automated assembly fixture for an automotive seat plate bracket assembly. The automotive seat plate bracket assembly 11 includes a plate bracket 9 and a sleeve 10. The bottom of the sleeve 10 has a flange extending outwards. The plate bracket 9 has a hole 12 and a screw hole 13 for accommodating the sleeve 10. The sleeve 10 passes through the hole 12, causing the flange to be tightly against the bottom of the plate bracket 9. The automated assembly fixture for the automotive seat plate bracket assembly is used to flange the top of the sleeve 10 and then tightly attach it to the top of the plate bracket 9.
[0043] The automated assembly fixture for the steel plate bracket assembly of the automobile seat includes a turntable 1 for placing the steel plate bracket 9, several positioning components disposed on the turntable 1 for fixing the steel plate bracket 9, and a first assembly mechanism 4, a second assembly mechanism 5, a third assembly mechanism 6, a fourth assembly mechanism 7, and a fifth assembly mechanism 8 sequentially disposed on the outer periphery of the turntable 1 along the rotation direction of the turntable 1.
[0044] The positioning components are respectively located on turntables 1 at the first assembly mechanism 4, the second assembly mechanism 5, the third assembly mechanism 6, the fourth assembly mechanism 7, and the fifth assembly mechanism 8.
[0045] The first assembly mechanism 4 is used to detect the torque of the screw hole 13 on the iron plate bracket 9;
[0046] The second assembly mechanism 5 is used to pre-press the top of the sleeve 10, so that the top of the sleeve 10 is folded outward to a certain extent;
[0047] The third assembly mechanism 6 is used to press the top of the sleeve 10, so that the top of the sleeve 10 is completely folded outward and pressed tightly against the top of the iron plate bracket 9;
[0048] The fourth assembly mechanism 7 is used to detect the diameter of the hole after the top of the sleeve 10 is folded outward;
[0049] The fifth assembly mechanism 8 is used to grab the assembled car seat iron plate bracket assembly 11 to the feeding port.
[0050] In this technical solution, the present invention optimizes the traditional assembly method by setting up a turntable 1, on which multiple positioning components for placing assembly parts are provided, and several assembly mechanisms are arranged along the circumference of the turntable 1. This makes the cycle time of each process more rationally matched and effectively improves production capacity. The entire production line only requires one operator to place the assembly parts into the positioning components, which greatly reduces enterprise costs.
[0051] More specifically, the first assembly mechanism 4 includes a first robotic arm 4-1 that moves up and down, and a screw hole torque detector 4-2 located at the end of the first robotic arm 4-1. The screw hole torque detector 4-2 is inserted into the screw hole 13 for testing. The screw hole torque detector 4-2 can be any type of instrument known to those skilled in the art for testing the torque of the screw hole 13.
[0052] The second assembly mechanism 5 includes a second robotic arm 5-1 that moves up and down, and a first cylinder located at the end of the second robotic arm 5-1. The piston of the first cylinder extends into the sleeve 10 and compresses it, causing the top of the sleeve 10 to fold outward to a certain extent. Preferably, the piston of the first cylinder extends into the sleeve 10 and compresses it, causing the top of the sleeve 10 to fold outward at 45°.
[0053] The third assembly mechanism 6 includes a third robotic arm 6-1 that moves up and down, and a second cylinder located at the end of the third robotic arm 6-1. The piston of the second cylinder extends into the sleeve 10 and squeezes it so that the top of the sleeve 10 is completely folded outward to the top of the iron plate support 9.
[0054] The fourth assembly mechanism 7 includes a fourth robotic arm 7-1 that moves up and down, and a pneumatic gauge located at the end of the fourth robotic arm 7-1. The pneumatic gauge is used to detect the aperture of the sleeve 10 after the top is completely folded outward. The pneumatic gauge can be any type of instrument known to those skilled in the art for detecting aperture.
[0055] The fifth assembly mechanism 8 includes a movable fourth robotic arm 8-1 and a gripper located at the end of the fourth robotic arm 8-1. The gripper is used to grab the car seat iron plate bracket assembly 11 to the discharge port.
[0056] The positioning component includes a tray 2 on the turntable 1 and a plurality of positioning blocks 3 on the tray 2. The space enclosed by the positioning blocks 3 is engaged with the iron plate support 9 to prevent the iron plate support 9 from detaching.
[0057] In addition, after the sleeve 10 and the iron plate bracket 9 are assembled, they need to be marked. Therefore, the automated assembly tooling for the iron plate bracket assembly 11 for automobile seats also includes a marking machine 11, which is used to mark the iron plate bracket assembly 11 for automobile seats. The marking machine 11 can be a laser marking machine.
[0058] Specific work process:
[0059] The worker inserts the top of the sleeve 10 through the hole 12 of the iron plate bracket 9, so that the flange at the bottom of the sleeve 10 fits against the bottom of the iron plate bracket 9. Then the iron plate bracket 9 with the sleeve 10 is placed into the positioning block 3 of the tray 2 for positioning.
[0060] Rotate the turntable 1, and the first assembly mechanism 4 will detect the torque of the screw hole 13 on the iron plate bracket 9;
[0061] Rotate the turntable 1 again to complete the pre-pressing of the top of the sleeve 10 through the second assembly mechanism 5, so that the top of the sleeve 10 is folded outward by 45°.
[0062] Rotate the turntable 1 again, and the third assembly mechanism 6 will press the top of the sleeve 10, so that the top of the sleeve 10 will be completely folded outward to the top of the iron plate bracket 9.
[0063] Rotate the turntable 1 again and use the fourth assembly mechanism 7 to check whether the diameter of the hole after the top of the sleeve 10 is completely folded outwards meets the standard.
[0064] Rotate the turntable 1 again and use the marking machine 11 to mark the iron plate bracket assembly 11 for the car seat;
[0065] Rotate the turntable 1 again, and use the gripper of the fifth assembly mechanism 8 to take away the iron plate bracket assembly 11 for the car seat, and place the finished product on the OK or NG feeding mechanism for output.
[0066] This invention optimizes the traditional assembly process of steel plate brackets for automotive seats, making the cycle time of each process more rationally matched and effectively improving production capacity. The entire production line requires only one operator, greatly reducing enterprise costs, while being equipped with numerous testing devices to ensure reliable quality. The assembly line layout is ingenious, minimizing the floor space required and reducing manufacturing costs.
