Detailed Description

As shown in fig. 1-2, a stamping device for automatic coil winding machine, includes the equipment base, connects in the copper wire feed arrangement of equipment base, connects in the coil stamping device of equipment base and connects in the coil winding machine of equipment base, the copper wire feed arrangement is including the copper wire feeding dish that is used for placing the copper wire of treating the processing, be used for driving rotatory first rotating electrical machines of copper wire feeding dish, connect in the flattening base of equipment base, connect a plurality of location rim plate on the flattening base and be used for driving rotatory second rotating electrical machines of location rim plate, the location rim plate divide into two sets ofly. Two sets of location rim plates are evenly arranged respectively in the left and right sides of flattening base, treat that the copper wire of processing passes through between two sets of location rim plates and respectively with two sets of location rim plate contacts, coil stamping device is including connecting in the punching press base of equipment base, connecting in the fixed bolster of equipment base, connecting in the slide bar of fixed bolster, sliding connection in the depression bar of slide bar, connecting in the mounting panel of depression bar, connecting the punching press head on the mounting panel and being used for driving the drive motor that the depression bar carries out reciprocating motion in vertical direction, the copper wire is followed copper wire feeding dish and is passed through flattening base and punching press base in proper order, finally accomplishes coil winding work at the coil coiling machine.

Firstly, a first rotating motor drives a copper wire in a copper wire feeding disc to feed, when the copper wire passes through a leveling base, a second rotating motor drives a positioning wheel disc to rotate, and the copper wire to be processed passes between two groups of positioning wheel discs and is respectively contacted with the two groups of positioning wheel discs, so that the copper wire can be shaped and straightened in the leveling device so as to facilitate the subsequent stamping processing procedure, when the copper wire enters the stamping base, a stamping rod is driven to press downwards in the vertical direction by a driving motor, and the stamping work is directly completed on the copper wire to be processed by the stamping head due to the fact that the stamping rod is provided with a mounting plate and a stamping head connected with the mounting plate, meanwhile, the time interval of the stamping head is controlled to reciprocate once to ensure that the positions of two stamped points on the copper wire are matched with the positions of two wire cakes after the copper wire is wound into a coil, and the copper wire completing the stamping work carries out coil winding and cutting work by a coil winding machine, compared with the traditional coil processing technology, the coil stamping process is directly completed in the feeding process, subsequent reprocessing is omitted, the production efficiency is greatly improved, and the production cost is reduced.

The device comprises a device base and is characterized in that a CCD detection device is arranged on the device base, the CCD detection device comprises a fixed column, a camera connected to the fixed column, an image transmission element used for transmitting image information shot by the camera, an image storage element used for storing standard punched copper wire shape images, an image comparison element used for comparing whether the punched shape of the copper wire in the image information shot by the camera is qualified or not, a calculation element used for calculating the time interval of the qualified punched copper wire shot twice and a feedback element used for feeding processing results back to a first rotating motor, a driving motor and a second rotating motor, and the feedback element is respectively and electrically connected with the first rotating motor, the driving motor and the second rotating motor.

The real-time picture information of the copper wire passing through the punching base is shot by the camera and then is transmitted to the image comparison element by the image transmission element, the image comparison element compares the shape picture of the copper wire after the standard punching with the image information transmitted by the camera, if the image information is qualified, the image information is marked as a first punching point, if the image information is qualified, the image information transmitted subsequently is marked as a second punching point, then the distance between the first punching point and the second punching point is calculated by the calculation element according to the time difference of shooting of the first punching point and the second punching point and the feeding speed of the copper wire, whether the length required by winding a standard coil is met is judged, if the length required by winding the standard coil is met, the feedback element does not work, the equipment continues to operate, and if the length required by winding the standard coil is not met, the first rotating motor, the second rotating motor and the driving motor are controlled to stop working by the feedback element, and the worker can debug the coil again to ensure that the produced coil is qualified.

The number of the stamping heads on the mounting plate is two, and the two stamping heads are in close contact.

In order to reduce the waste of copper wires, the waste between two coils of coiling is required to be reduced as much as possible, therefore, when the punching heads are required to punch at every time, continuous punching is required twice, but the working efficiency is lower, the punching is not sufficient easily, the copper wires are not deformed in place, and the subsequent welding work is influenced.

The coil stamping device further comprises a positioning plate connected to the stamping rod, a limiting rod connected to the positioning plate and a buffer spring connected to the limiting rod, the mounting plate is connected to the limiting rod in a sliding mode, and two ends of the buffer spring are fixedly connected to the positioning plate and the mounting plate respectively.

Because coil stamping device still including connecting in the locating plate of stamping rod, connect in the gag lever post of locating plate and connect the buffer spring on the gag lever post, after the line cake contact on stamping head and the coil, the line cake can exert reaction force for the stamping head, because buffer spring both ends difference fixed connection is in locating plate and mounting panel, and the mounting panel can slide on the gag lever post, consequently, the stamping head receives after the reaction force to transmit this effort for buffer spring through the mounting panel, buffer spring exerts a buffer force for the mounting panel again, thereby avoid the stamping head to lead to the excessive deformation of line cake for the impact force that the line cake in the coil was exerted, greatly reduced the defective percentage.
