When assembling the nest-like tweed and the gasket, the needle 4423 abuts against the pin, the cylinder 441 is pressed down, the needle 4423 is retracted into the first section 44132, the nest-like tweed and the gasket are pressed down on the bottom surface of the cylinder 441, the nest-like tweed and the gasket are separated from the plug-in portion 44231 and are sleeved with the pin downwards, after the assembly is completed, the penetrating piece 44 is removed, the contact pin 442 is reset under the action of the spring 443, and the needle 4423 is exposed out of the cylinder 441 again.
As shown in fig. 1-2, in this embodiment, four assembly combinations are disposed at intervals, corresponding to four rows of pins on the penetrating key frame 100, respectively. Each assembly combination comprises four nest-like tweed feeding mechanisms 5, one gasket feeding mechanism 3 and one penetrating mechanism 4. The four penetrating and matching combinations are synchronously carried out, so that the operation efficiency can be improved. In other embodiments, the number of assembly combinations may be adjusted according to the actual situation.
The working principle of the key frame nest-entering tweed machine is as follows:
1. Placing the key frame 100 on a pneumatic clamping table 21, pressing the key frame 100 by a clamping cylinder 212 and a pressing cylinder 214, and moving the key frame 100 to an assembling position under the drive of a screw rod driving mechanism 22, wherein a pin to be penetrated is positioned below the channel 111;
2. The nest-shaped woolen reaches a discharge hole of the linear vibrator 52 through the first vibration disc 51 and the linear vibrator 52 to be grabbed by the penetrating adapter 44;
3. The gasket reaches the outlet end of the delivery path 3221 via the second vibration tray 31 and the gasket feeder 32;
4. The manipulator drives the penetrating adapter 44 to sequentially insert the nest-like tweed of the discharge hole of the linear vibrator 52 and the gasket at the outlet end of the conveying channel 3221.
5. The mechanical arm moves the penetrating piece 44 to be above the corresponding pin, and the penetrating piece 44 presses the nest tweed and the pin into the pin 101;
6. The pneumatic clamping table 21 drives the key frame 100 to continue to advance, and the manipulator drives the penetrating adapter 44 to penetrate the next pin until the penetrating of the pin is completed.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
