[0037] like Figure 7 The billiard ball grabbing structure of Example 2 is shown. The billiard ball grabbing structure 13 includes a suction cup base 13021, which is arranged on the lower end surface of the support plate 1. A through hole is provided in the suction cup base 13021. A rubber suction cup 13022 is provided in the suction cup base 13021. The outer diameter of the rubber suction cup 13022 is larger than the diameter of the suction cup base 13021. The bottom end of the suction cup base 13021 is provided with an arc segment, which has a clamping and positioning effect on the rubber suction cup 13022. The lower end portion of the optical axis 11 is fixedly connected to the top of the rubber suction cup 13022.

[0038] Preferably, the ball barrel and the suction cup base can be separated from the support plate, such as Figure 5 , Figure 6 and Figure 7 As shown, it can also be an integrated structure, such as Fig.11 As shown, all are within the protection scope of the present invention.

[0039] The use process of embodiment 1 of a device for simultaneously picking up and placing multiple balls of the present invention is that the present invention can be used in a swing ball machine. When used in the swing ball machine, the present invention is first in an inverted state (i.e., the support plate 1 is at the upper end and the pull rod base 2 is at the lower end). At this time, the bearing 12 is located on a relatively low horizontal section of the ramp hole 3, the optical axis 11 and the lifting member 13014 are both at the lowest position, and the grabbing fingers 13016 are in an open state. The ball grabbing claws on the swing ball machine place the balls into the grabbing fingers 13016 of the present invention respectively, and then the sliding drive mechanism 10 is opened, the gear 8 rotates, and the rack 9 meshes with the gear 8 for transmission, so that the rack 9 drives the pull rod base 2 to slide to the left. At the same time, the bearing 12 moves in the ramp hole 3 as the pull rod base 2 slides to the left, and the bearing 12 moves from the first horizontal section to the inclined upward section and then to the second horizontal section. During the movement of the bearing 12, a height difference occurs in the relative position of the bearing 12, and the optical axis 11 fixedly connected thereto also The lifting member 13014 is driven to produce a height difference with the initial position, and the lifting member 13014 moves in the strip hole 13015 of the grabbing finger 13016 toward the direction close to the support plate 1. During this process, the grabbing finger 13016 clamps the ball, and the sliding drive mechanism 10 is closed at this time. Then, after a certain action of the swing ball machine in the swing ball machine, the present invention completes the flip. After flipping, the support plate 1 is at the lower end, and the pull rod base 2 is at the upper end. The sliding drive mechanism 10 is opened again in the opposite direction of the previous rotation, and then the gear 8 rotates in the opposite direction, driving the rack 9 to slide to the right, so that the bearing 12 moves in the ramp hole 3, and the lifting member 13014 moves in the strip hole 13015 of the grabbing finger 13016 toward the direction away from the support plate 1. During this process, the grabbing finger 13016 releases the ball, and then after the ball is put down, the present invention starts to move upward in the swing ball machine. During the operation of the swing ball machine, the present invention completes the clamping of the ball and accurately puts down the ball at the correct position. In this embodiment, the bar-shaped hole 13015 on the grasping finger 13016 is hinged to the lifting member 13014, thereby shortening the up and down travel of the lifting member 13014, thereby controlling the opening and closing degree of the grasping finger 13016. Fig.10 As shown, the positions of the three grasping fingers 13016 avoid the contact points of the two balls, which can effectively avoid the influence of the grasping fingers 13016 on the position of the ball and ensure the accuracy of the position of the ball.

[0040] The principle of embodiment 2 of the device for simultaneously taking and placing multiple balls of the present invention is the same as that of embodiment 1. When the ball is put in, the bearing 12 pulls the rubber suction cup 13022 in contact with the ball, and the middle position of the rubber suction cup 13022 is pulled, and the outer portion is pressed by the suction cup base 13021, thereby sucking the ball. After the present invention is turned over, the bearing 12 returns to its original position, and the rubber suction cup 13022 is released, so that the ball is released and falls.

[0041] The present invention is not limited to the application to the picking and placing of billiard balls, but can also be applied to the grabbing of other balls. The number and position of the specific grabbing mechanism can be changed as needed, all within the protection scope of the present invention.
