Example 2:

This embodiment is a specific implementation of the first embodiment. The second driving mechanism in this embodiment includes a linear power source and a transmission rod 14.

The middle part of the transmission rod 14 is hinged to the bottom of the upper box body 2. It is worth noting that the upper box body 2 also includes a box cover 3 that covers the top box opening of the upper box body 2. The bottom of the box 2 is provided with a circular groove, the bottom surface of the box cover 3 is provided with a circular sleeve coaxial with the circular groove, the middle of the transmission rod 14 is provided with a vertical circular rod, the upper and lower ends of the circular rod are respectively The rotation is inserted into the circular groove and the circular sleeve, so that the middle part of the transmission rod 14 can be hinged to the bottom of the upper box body 2, that is, the transmission rod 14 can rotate horizontally in the upper box body 2.

One end of the transmission rod 14 is provided with a shaft sleeve 141, the bottom of the upper box body 2 is provided with an arc-shaped notch, and one end of the above-mentioned gripper 6 is provided with an upwardly facing cylinder 61, which penetrates the arc from bottom to top. It is inserted into the notch and rotated and inserted into the sleeve 141. At this time, when the transmission rod 14 rotates, it will drive the above-mentioned gripper 6 to move in the lower box body 4. The other end of the gripper 6 is provided with a C-shaped block 62 The C-shaped block 62 is equivalent to a cotton swab holder, which is used to clamp the cotton swab 1 so that the cotton swab 1 moves with the C-shaped block 62 and the gripper 6.

The linear power source is installed on the upper box body 2 and used to drive the other end of the transmission rod 14 to rotate, thereby driving the transmission rod 14 and the shaft sleeve 141 to rotate. The shaft sleeve 141 will rotate around the round rod, which will drive the gripper. The hand 6 moves in the lower box body 2. The above-mentioned cylinder 61 is provided with a slider 63 which is overlapped on the edge of the arc-shaped notch to support the entire gripper 6 by gravity. The second driving mechanism also includes a guide assembly, which is installed in the upper box body 2, and the slider 63 facilitates the abutment of the guide assembly. By using the abutting relationship between the guide assembly and the slider 63, The movement of the gripper 6 in the lower box body 4 can be guided and restricted. Since the gripper 6 is actually hinged to the transmission rod 14 through the cooperation of the cylinder 61 and the shaft sleeve 141, if it is not guided, the movement of the gripper 6 in the lower box body 4 will be chaotic when the transmission rod 14 is rotated. However, through the setting of the above-mentioned guide assembly, the cooperation between it and the slider 63 will make the gripper 6 move in the lower box 4 to drive the C-shaped block 62 to grab the cotton swab 1 from the side, and then face the cotton swab口Translation.

As a specific implementation of this embodiment, the guide assembly in this embodiment includes a guide block 15 and a second spring 16. The guide block 15 has an outer wall 151 with a gradually increasing radius of curvature. The guide block 15 is laid on the upper box. The bottom wall of the body 2 is located on the inner side of the arc-shaped notch, and the A outer wall 151 is a side wall of the guide block 15 close to the arc-shaped notch, and the center of the A outer wall 151 and the arc-shaped center of the arc-shaped notch are on the same side And the slider 63 is a circular plate structure. When the transmission rod 14 drives the gripper 6 to move along the arc-shaped notch, the outer wall 151 of the guide block 15 always abuts the slider 63, and the slider 63 and The above-mentioned C-shaped blocks 62 are respectively located on both sides of the cylinder 61. When the sliding block 63 is resisted by the guide block 15 and the guide block 15 drives the gripper 6 to rotate, the C-shaped block 62 will make a parabolic motion in the lower box body 4, thereby Stick it on the cotton swab 1 from the side.

The guide block 15 is provided with a spring mounting seat 152. The spring mounting seat 152 has a plunger.

In this way, when the transmission rod 14 drives the gripper 6 to rotate, the slider 63 is always pressed on the guide block 15, thereby driving the second spring 16 to compress. When the C-shaped block 62 clamps a cotton swab 1, the remaining cotton swabs The blocking effect of 1 prevents the C-shaped block 62 from continuing to move in a curve, and the gripper 6 still moves in an arc along the arc-shaped gap with the transmission rod 14, but because the second spring 16 is compressed, this In this case, the second spring 16 is gradually released, thereby exerting a pushing force on the slider 63. The slider 63 and the C-shaped block 62 are located on both sides of the above-mentioned cylinder 61, so the C-shaped block 62 will have a function of being away from the remaining cotton swabs 1. This force interacts with the force exerted by the transmission rod 14 on the gripper 6 and cancels each other in displacement, so that the C-shaped block 62 moves forward in a straight line, thereby pushing the cotton swab 1 forward and from The above-mentioned sign-off gate was launched.

With this structure, the return displacement of the second spring 16 and the arc-shaped displacement of the gripper 6 are ingeniously offset each other to ensure that the C-shaped block 62 can drive the cotton swab 1 forward, and this structure ensures that the gripper 6 can grasp the lower box body 4 Cotton swab 1 in any posture within 4 and push it out of the lottery exit.
