For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0018] As Figure 1 shown, the mechanical conversion device of the circular array includes: A substrate 1, on which a plurality of circular guide holes are provided. The circular guide holes are arranged, and a unit component 2 is provided in the circular guide holes; A conversion control board 3, which is arranged above the substrate 1 and is provided with circular through holes corresponding to the substrate 1. A driving sleeve 4 is provided in the circular through holes. One end of the unit component 2 is slidably connected to the driving sleeve 4, and the other end is used to connect a grasping device; A driving device 5, which is connected to the base 1 through a support frame 51. The piston rod 52 of the driving device 5 passes through the support frame 51 and is fixedly connected to the conversion control board 3 downward; Among them, the circular guide holes are arranged at the midpoint of the distance between the conversion of the circular array and the square array of the unit component 2. The driving device 5 drives the conversion control board 3 to move up and down, so that the driving sleeve 4 drives the unit component 2 to swing and turn to the node of the square array or the node of the circular array.

[0019] As Figure 2 and Figure 3As shown, in the legend, it is a 6×6 square array, that is, there are 36 nodes F (labeled F1 to F36) in the square array; in the legend, the circular array has three circles. The inner circle has 6 nodes, the middle circle has 12 nodes, and the outer circle has 18 nodes, totaling 36 nodes Y (labeled Y1 to Y36). This device realizes the mutual conversion between the square array and the circular array of 36 nodes.

[0020] As Figure 1 shown, the substrate 1 is a plate (see the appendix Figure 1 ), and a series of circular guide holes are provided on the substrate 1. The number of circular guide holes is the same as the number of nodes constituting the array.

[0021] As Figure 5 shown, each circular guide hole on the substrate 1 is respectively located at the midpoint M1 position of the line connecting a certain node in the square array, such as F1, and the corresponding node Y1 closest to F1 after the array is converted into a circular array. Thus, the center positions (M1 to M36) of each circular guide hole on the substrate 1 can be determined respectively.

[0022] Mark the distance between the node F in the square array and the closest node Y in the circular array as 2R, that is, the distance between the node F1 in the square array and the closest node Y1 in the circular array is 2R1,..., and the distance between the node F36 in the square array and the closest node Y36 in the circular array is 2R36. After statistics, the distance 2R between the nodes in this array transformation example has 7 specifications (the array specifications with different numbers of nodes are different).

[0023] As Figure 1 shown, the conversion control board 3 is a plate, located above the substrate 1, parallel to the substrate 1 and arranged to move up and down. A series of circular through holes are provided on the conversion control board 3, and the positions of each circular through hole correspond to the series of circular guide holes provided on the substrate 1.

[0024] As Figure 4 shown, a set of unit components is respectively rotatably provided at each circular guide hole on the substrate 1. Each set of unit components 2 includes a rotating shaft 21, an eccentric connecting plate 22, a sleeve 23, a gasket 24, a screw shaft 25, and a connecting seat 26.

[0025] The rotating shaft 21 passes through the circular guide hole on the substrate 1, is rotatably arranged with the substrate (bearing seats and bearings can be provided), and passes upward through the conversion control board 3. At the lowermost end of the rotating shaft 21, an eccentric connecting plate 22 is fixedly provided. Below the eccentric connecting plate 22 (which can be through screws), a connecting seat 26 is offset and fixedly provided for connecting grasping devices such as clamping jaws and suction cups. The eccentric distance between the axis of the offset connecting seat 26 and the axis of the rotating shaft 21 is R, which is half of the distance 2R between the circular array node Y closest to the square array node F. The eccentric distances R of the axis lines of the connecting seats 26 corresponding to the unit components at different positions of the circular guide holes (M1 to M36) are respectively marked as R1, …, R36. (There are 7 specifications in this array transformation example).

[0026] A sleeve 23 is provided between the substrate 1 and the eccentric connecting plate 22. A large-lead screw shaft 25 is fixedly sleeved on the rotating shaft 21 above the substrate 1. A gasket 24 is provided between the lower end of the screw shaft 25 and the substrate 1. The screw shaft 25 slides (or moves) upward through the conversion control board 3.

[0027] A driving sleeve 4 is fixedly provided on the conversion control board 3. The inner hole of the driving sleeve 4 is in sliding fit with the outer circle of the screw shaft 25. A guide pin 41 is radially fixedly provided on the driving sleeve 4, and the guide pin 41 is in sliding fit with the spiral groove of the screw shaft 25. The structure of the driving sleeve 4 and the guide pin 41 can be directly replaced by a spiral sleeve.

[0028] In this example, the driving device 5 is a cylinder, which is fixed by a support frame 51 fixedly connected to the substrate 1 and is located at the upper middle position above the conversion control board 3. The piston rod 52 passes through the support frame 51 downward and is fixedly connected to the conversion control board 3.

[0029] The cylinder controls the conversion control board 3 and the driving sleeve to move up and down, driving the screw shaft 25 to drive each unit component to rotate synchronously in the same direction, clockwise or counterclockwise, by 180 degrees. The lower offset connecting seats 26 respectively swing to the square array nodes or the circular array nodes.

[0030] The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
