Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

Please refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:

A reciprocating automatic feeding mechanism, the reciprocating automatic feeding mechanism includes a mounting base 1, a swing cylinder 2, a driving arm 3, an adjustable follower arm 4, a guide rail 5, a roller 6 and a suction cup 7, and the mounting base 1 is installed There is a swing cylinder 2 with double output shafts, one output shaft of the swing cylinder 2 is fixed on one end of the driving arm 3, the other end of the driving arm 3 is movably connected to one end of the adjustable driven arm 4, and the other end of the adjustable driven arm Pulley 6 and sucker 7 are installed, and pulley 6 and sucker 7 are positioned at the both sides of adjustable driven arm 4; Track 5 is installed along the direction of drive arm 3 on the mount 1, and pulley 6 slides in track 5; The swing The cylinder 2 is a 180° swing cylinder, and the other output shaft of the swing cylinder 2 is equipped with a limit pendulum iron 8, and a limit switch 9 is provided at a position corresponding to the limit pendulum iron 8; the adjustable driven arm 4 includes a front telescopic adjustment rod 41 and the rear telescopic adjustment rod 42, which also includes an adjustment card slot 43 arranged on the front telescopic adjustment rod 41 and the rear telescopic adjustment rod 42, and the adjuster 10 is fixed on the adjustment of the front telescopic adjustment rod 41 and the rear telescopic adjustment rod 42 In the card slot 43; the regulator 10 includes a housing 101, a spring 102 and a snap bead 103. The two ends of the spring 102 are provided with positioning snap beads 103 and are installed in the housing 101 together. A part of the two snap beads 103 The casing 101 is exposed, and is locked in the slot of the adjustable driven arm; buffers 11 are provided at the two extreme swing positions of the driving arm 3 .

The working mode of a reciprocating automatic feeding mechanism in the present invention is as follows: the swing cylinder is a pneumatic actuator that uses compressed air to drive the output shaft to perform reciprocating rotary motion within a certain angle range, and adopts a swing range of 180° (or select the swing range as required) . The swing cylinder swings to drive the driving arm to swing, and the driving arm drives the driven arm to move. The other section of the driven arm is equipped with a suction cup and a roller, and the roller slides in the guide rail.

In this mechanism, the swing cylinder can also be in the form of a hydraulic swing cylinder. The slave arm is adjustable, and the length of the slave arm is adjusted by the movement of the adjuster. The adjuster has a built-in spring, and there are steel balls at both ends of the spring, and the steel balls can be embedded in the groove to form a positioning. A change in the length of the slave arm will result in a change in the stroke of the suction cup's linear motion. Adjust its length according to the needs of the work.

When swinging 180°, the moving speed of the suction cup changes into a sinusoidal curve with time, and buffers are installed on both sides of the driving arm lever, because when swinging 180°, the driving arm moves at the limit position on both sides, and there will be an impact, so Shock absorbers can be used to cushion the impact.

The reciprocating automatic feeding mechanism of the invention has lower cost, higher efficiency and certain flexibility and adjustability.

The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related technologies fields, all of which are equally included in the scope of patent protection of the present invention.
