Abstract

The invention relates to the deposition of electroplated coatings, in particular, devices for fastening machine sewing needles to a conductor. The purpose of the invention is to increase productivity and save materials. Previously in the hopper 2 download the fins, oriented bulb to the left, set the cassette and turn on the machine. The needles from the hopper are moved by the feed screw 4 along the plug, oriented along the eyelet and groove when juxtaposed with the rotating contact roller and are set in a row on the mounting platform. After installing a specified number of needles, the software-setting device 6 turns off the muff-. coupling, stopping the rotation of the feeder viit 4. When the eccentric is rotated, the needles are clamped along the ends between the cassette guide bars. The cartridge, filled with needles, is removed from the semiautomatic device, then the cycle of operation is repeated. The semiautomatic device allows eliminating manual labor while orienting needles and obtaining material savings. I zp f-ly, 4 ill. (L ttiyt.1

The invention relates to electroplating devices, in particular to devices for attaching machine sewing needles to a conductor.

The purpose of the invention is to increase productivity and save materials,

FIG. 1 shows an automatic machine for preparing sewing needles for electroplating, a general view: in FIG. 2 shows section A-A in FIG. 1;: FIG. 3 shows an orientation device, type B in FIG. 2; figure 4 - device installation and fixing the needles in the cassette, type B in fig.I.

The automatic preparation of psynzh needles for electroplating coatings consists of 1 hopper 2 for needles mounted on a frame, a support plate .3, a feed screw 4, a device 5 5 for needle orientation and a groove, a software driver 6, a device 7 for installing and fixing needles in the cassette, clutch 8 clutch, per 25 ductor 9 and electric motor 10.

The needle orientation device 5 is made in the form of a contact roller 11 driven by a gearmotor 12, the latter being mounted on guide pins 13 screwed into the support plate 3 and damped by springs 14 put on studs.

The device for mounting and fixing the needles in the cassette consists of the base plate 3, the feed screw 4, the restrictor bars 15 and 16, the brackets 17 and 18 with the bar, the springs 19, the eccentric 20 with the handle and the locking bar 21 .:

The machine works as follows.

Previously in the hopper 2 load needles, oriented flask to the left, set the cassette 22 and turn on the machine. The rotation from the electric motor 10 is transmitted through the clutch 8, the gearbox 9 and the chain gear 23 to the feed screw 4. At the same time, the gear motor 12 of the needle orientation device 5 turns the contact roller 11. The peripheral speed of the roller 11 is six times the peripheral speed of the feed screw 4 that ensures timely15

Needle Orientation. The needles from the hopper 2 are moved by the screw 4 along the stop bar 15, are oriented along the eyelet and groove in contact with the rotating contact roller 11, and line up in a row on the base plate 3 with the interval between the flasks of the needles, equal to their diameter. After setting a predetermined number of needles, the programmer 6 disconnects the clutch 8, thereby stopping the rotation of the feed screw 4. When the eccentric 20 rotates, the needles are clamped at the ends of the movable 5 bar of the cassette 22. The last needle filled is removed from the machine and replaced in its place empty. When the eccentric 20 is rotated, the movable bar of the cassette 22 is retracted. Then the cycle of operation is repeated.

The use of new elements — device orientation of machine sewing needles along the eyelet and groove and needle fixing devices in the cassette — allows mechanizing the installation of parts on the conductor, thereby eliminating the monotonous manual work on installing the needles and reducing the consumption of copper conductor used previously for viscous details.
