Detailed Description

As shown in fig. 1, in the mask ear strip line stretching swing arm, a servo motor 21 is vertically installed at the top of a lifting support 24, a rotating shaft 20 is butted with an output port at the bottom of the servo motor 21, the top of the rotating shaft 20 is in transmission butt joint with a sleeve shaft installed at the top of a bearing seat 19, the bottom of the bearing seat 19 is in butt joint with an output port of a cylinder through a second transmission rod 22, a first carrier arm 10 and a second carrier arm 11 are transversely sleeved at the upper end and the lower end of the sleeve shaft respectively, a sliding mechanism is installed between the first carrier arm 10 and the second carrier arm 11 in a connecting manner, a strip line shifting punching column 16 is installed at the bottom of a bottom plate 15 fixedly connected with the bottom of the sliding mechanism, and the strip line shifting punching column 16. Wherein, whole equipment accessible PLC control system controls processing. The servo motor 21 is started to drive the rotating shaft 20 to rotate directionally, and the first loading arm 10 and the second loading arm 11 can be driven to rotate synchronously in the rotating process of the rotating shaft 20; during the rotation, the pushing action of the sliding mechanisms on the first and

second carrier arms

10 and 11 and the lifting support 24 can be completed by two sets of cylinders arranged at the bottom and the top, so as to adjust the extension length of the ear belt line. In the process of swinging the first loading arm 10 and the second loading arm 11, the line-pulling stamping column 16 of the bottom plate 15 at the bottom of the second loading arm 11 can stretch the ear belt line 14 which is transported in a straight line to the side; after stretching to a designated length, the wire-drawing stamping column 16 is in stamping butt joint with the ear belt wire butt joint seat 17, the cylinder which extends longitudinally at the moment is started to do retraction movement, at the moment, the wire-drawing stamping column 16 is stamped downwards, and the ear belt wire 14 which is placed at the bottom of the ear piece 18 is buckled into the bottom of the ear piece 18 on the ear belt wire butt joint seat 17 in a clockwise manner. The punching combination of the lug wire butt joint seat 17 and the wire pulling punching column 16 can adopt a spring type ball pen push structure. Meanwhile, in the process of ejection, the steering of the ear piece 18 can be adjusted due to the ejection structure of the simulated spring type ball-point pen. The laterally arranged ear pieces 18 are rounded at the outer end due to their small size. The ear strap wires 14 are prevented from hanging on the upper end surfaces of the ear pieces 18. The longitudinally arranged ear pieces 18 are designed to retain the ear strap wires 14 and prevent the ear strap wires at the bottom of the ear pieces 18 from being turned over until the ear strap wires 14 are cut and the heat welding process is completed. The ear straps are limited to 90 degree rotation of the mating ear piece 18 on the loading end of the docking station 17.

As shown in fig. 1, the sliding mechanism includes a first limit slider 6 and a second limit slider 13, the first limit slider 6 and the second limit slider 13 are respectively installed in the sliding grooves 7 of the first carrying arm 10 and the second carrying arm 11, the first limit slider 6 and the second limit slider 13 are connected through a telescopic loop bar 12, the bottom of the second limit slider 13 is fixedly connected with a bottom plate 15, and a horizontal transmission mechanism 2 is installed at the top of the first limit slider 6. In order to load a sliding mechanism with the function of transverse pushing and jacking, the first limiting slide block 6 and the second limiting slide block 13 are matched to complete up-and-down telescopic movement, and meanwhile, synchronous swinging is also kept. A telescopic loop bar 12 is arranged between the first limit slide block 6 and the second limit slide block 13. The telescopic sleeve rod 12 can complete the lifting motion process by matching with the wire-shifting stamping column 16. Meanwhile, the double telescopic loop bars 12 arranged side by side have better combination stability.

As shown in fig. 1, horizontal drive mechanism 2 includes cross movable block 1, the fixed butt joint of sleeve axle 5 at butt joint port and the 6 tops of first spacing slider of 1 bottom surface of cross movable block, the butt joint is installed two sets of first transfer lines 3 on the horizontal terminal surface of cross

movable block

1, 3 right side ends of first transfer line dock with cylinder output end, the cylinder is installed on pilot hole 9, pilot hole 9 is seted up on the platform 8 that first year arm 10 right side extends. Wherein, the cross movable block 1 can use the structure of the cross end surface to do the multi-direction installation butt joint process. The sleeve shaft 5 synchronously installed with the sliding block can drive a limiting slide block 6 and a second limiting slide block 13 to move horizontally in the sliding groove 7.

As shown in fig. 1, the ear piece 18 is fixedly mounted on both the wire drawing punch post 16 and the ear wire splicing seat 17. Wherein the ear piece 18 can selectively hang the ear strap 14.

As shown in fig. 1, a synchronous positioning pin 4 is inserted into the top of the sleeve shaft, a U-shaped slot rotating disc is installed between the upper end of the sleeve shaft and the first carrying arm 10, and a U-shaped slot rotating disc is installed between the lower end of the sleeve shaft and the second carrying arm 11. The U-shaped groove rotating disc can increase the contact surface of the first load arm 10 and the second load arm 11, and simultaneously limit the swinging space of the first load arm 10 and the second load arm 11, so that the first load arm 10 and the second load arm 11 are forced to synchronously rotate with the rotating shaft 20.
