The screw 20a and the screw 20b can rotate forward and backward around the axes thereof. The screw 20a and the screw 20b are of an integral structure and at least comprise a first screw section and a second screw section with opposite rotation directions. The first thread segments are located on the left side in fig. 1 and the second thread segments are located on the right side in fig. 1. The thread leads of the first thread segment and the second thread segment are equal. The thread lead of screw 20b is 2 times the thread lead of screw 20 a.

The first movable member 30b, the first movable member 30a, the fixed member 50, the second movable member 40a, and the second movable member 40b are sequentially disposed at equal intervals along the X-axis direction, and are respectively connected to the five adsorption members 70.

The fixing member 50 is fixedly disposed on the mounting base 10.

The first movable member 30a is screwed to the first thread section of the screw 20a, and a transmission structure is formed between the first movable member and the screw 20a, so that the rotational motion of the screw 20a can be converted into the linear motion of the first movable member 30a along the axial direction of the screw 20 a.

The first movable member 30b is screwed to the first thread section of the screw 20b, and a transmission structure is formed between the first movable member and the screw 20b, so that the rotational motion of the screw 20b can be converted into the linear motion of the first movable member 30b along the axial direction of the screw 20 b.

The second movable member 40a is screwed to the second thread section of the screw rod 20a, and a transmission structure is formed between the second movable member and the screw rod 20a, so that the rotary motion of the screw rod 20a can be converted into the linear motion of the second movable member 40a along the axial direction of the screw rod 20 a.

The second movable member 40b is screwed to the second thread section of the screw 20b, and a transmission structure is formed between the second movable member and the screw 20b, so that the rotary motion of the screw 20b can be converted into the linear motion of the second movable member 40b along the axial direction of the screw 20 b.

The first driving member 63 is disposed on the mounting seat 10 for respectively driving the screw rods 20a and 20b to rotate synchronously. The specific driving manner of the first driving member 63 is described in detail below.

The first movable member 30a, the first movable member 30b, the second movable member 40a and the second movable member 40b linearly move under the driving of the screw 20a and the screw 20b, and then the distance between two adjacent suction members 70 in the five suction members 70 connected to the first movable member 30a, the first movable member 30b, the fixed member 50, the second movable member 40a and the second movable member 40b is equally adjusted.

The working principle is as follows:

on one hand:

when the first driving member 63 drives the screw 20a and the screw 20b to rotate forward, the first movable member 30b and the first movable member 30a move away from the stationary member 50 synchronously, the moving speed of the first movable member 30b is twice that of the first movable member 30a, and the distance between the first movable member 30b and the first movable member 30a increases by an amount equal to the distance between the first movable member 30a and the stationary member 50.

When the first driving member 63 drives the threaded rod 20a and the threaded rod 20b to rotate reversely, the first movable member 30b and the first movable member 30a synchronously approach the stationary member 50, the first movable member 30b moves twice as fast as the first movable member 30a, and the distance between the first movable member 30b and the first movable member 30a decreases by a value equal to the distance between the first movable member 30a and the stationary member 50.

Because the first movable element 30b, the first movable element 30a, and the fixed element 50 are sequentially arranged at equal intervals, and in the rotating process of the threaded rod 20a and the threaded rod 20b, the variable of the interval between two adjacent movable elements 30b, 30a, and 50 is equal, the first movable element 30b, 30a, and 50 can always be arranged at equal intervals, and the interval between two adjacent movable elements can be increased or decreased.

On the other hand:

when the first driving member 63 drives the screw 20a and the screw 20b to rotate forward, the second movable member 40a and the second movable member 40b move away from the fixed member 50 synchronously, the moving speed of the second movable member 40b is twice that of the second movable member 40a, and the distance between the second movable member 40b and the second movable member 40a increases by an amount equal to the distance between the second movable member 40a and the fixed member 50.

When the first driving member 63 drives the threaded rod 20a and the threaded rod 20b to rotate reversely, the second movable member 40a and the second movable member 40b synchronously approach the fixed member 50, the moving speed of the second movable member 40b is twice that of the second movable member 40a, and the reduction value of the distance between the second movable member 40b and the second movable member 40a is equal to the reduction value of the distance between the second movable member 40a and the fixed member 50.

Because the fixed member 50, the second movable member 40a, and the second movable member 40b are sequentially arranged at equal intervals, and in the rotation process of the threaded rod 20a and the threaded rod 20b, the variable of the interval between two adjacent fixed members 50, the second movable member 40a, and the second movable member 40b is equal, the fixed member 50, the second movable member 40a, and the second movable member 40b can always be arranged at equal intervals, and the interval between two adjacent movable members can be increased or decreased.

In another aspect:

when the first driving member 63 drives the screw 20a and the screw 20b to rotate forward, the first movable element 30a and the second movable element 40a are synchronously away from the fixed element 50, the moving speeds of the first movable element 30a and the second movable element 40a are equal, and the distance between the first movable element 30a and the fixed element 50 is increased by the same value as the distance between the second movable element 40a and the fixed element 50.

When the first driving member 63 drives the threaded rod 20a and the threaded rod 20b to rotate reversely, the first movable member 30a and the second movable member 40a synchronously approach the stationary member 50, the moving speeds of the first movable member 30a and the second movable member 40a are equal, and the distance between the first movable member 30a and the stationary member 50 is reduced by the same value as the distance between the second movable member 40a and the stationary member 50.

Because the first movable element 30a, the fixed element 50 and the second movable element 40a are sequentially arranged at equal intervals, and in the rotating process of the screw rod 20a and the screw rod 20b, the variable of the interval between two adjacent movable elements 30a, 50 and 40a is equal, the first movable element 30a, the fixed element 50 and 40a can always be arranged at equal intervals, and the interval between two adjacent movable elements can be increased or decreased.

In summary, the first movable member 30b, the first movable member 30a, the fixed member 50, the second movable member 40a, and the second movable member 40b can always be arranged at equal intervals, and the interval between the two adjacent movable members can be increased or decreased. Thereby enabling the five adsorption assemblies 70 to be always arranged at equal intervals, and the interval between the two adjacent adsorption assemblies can be increased or decreased.

In this embodiment, the screws 20a and 20b are all of an integral structure, and both include a first thread section and a second thread section with opposite rotation directions. Compared with the prior art, the coupler for connecting the first thread section and the second thread section is omitted, the assembling steps are reduced, the assembling difficulty is reduced, and the coaxiality of the first thread section and the second thread section can be ensured.

The first movable member 30b, the first movable member 30a, the second movable member 40a and the second movable member 40b are slidably engaged with the mounting base 10 along the X-axis, so as to ensure more stable movement.

The equal interval adjusting apparatus 100 further includes two driven wheels 61 and a transmission member 62.

Two driven pulleys 61 are coaxially fixed to the screw rods 20a and 20b, respectively. At least one driven wheel 61 is adjustable in the circumferential position of the screw 20a or the screw 20 b. Specifically, in the present embodiment, one of the driven pulleys 61 is pin-keyed to the screw 20 a. The other driven wheel 61 is connected with the screw rod 20b through an anchor ear, so that the circumferential position of the driven wheel 61 on the screw rod 20b can be adjusted.

The transmission members 62 are respectively engaged with the driven wheels 61 to convert the movement of the transmission members 62 into the rotation of the driven wheels 61.

The first driving member 63 is used for driving the transmission member 62 to move.

When the transmission member 62 is engaged with each driven wheel 61, the screw 20a and the screw 20b cannot rotate freely due to the limitation of the first movable member 30b, the first movable member 30a, the second movable member 40a, and the second movable member 40b, and it is not guaranteed that each driven wheel 61 can be engaged with the transmission member 62. In the present embodiment, the position of the driven wheel 61 in the circumferential direction of the screw 20b can be adjusted, and if the engagement is not possible, the position of the driven wheel 61 may be adjusted.

In this embodiment, the transmission member 62 is a timing belt. The first driving member 63 drives the transmission member 62 to move as follows.

The equidistant adjustment device 100 further comprises a driving wheel 64 and two tensioning wheels 65.

The synchronous belt is respectively wound on the two driven wheels 61 and the driving wheel 64, the synchronous belt is meshed with the driving wheel 64, and the first driving piece 63 is used for driving the driving wheel 64 to rotate so as to drive the synchronous belt to move. Specifically, the first driving member 63 may be a motor, and the driving wheel 64 is coaxially disposed on an output shaft of the motor, and the motor can drive the driving wheel 64 to rotate forward and backward.

The two tension pulleys 65 respectively abut against the timing belt to tension the timing belt.

In another embodiment, the transmission member 62 may be a gear, the gear is engaged with the two driven wheels 61, and the first driving member 63 directly drives the gears to rotate forward and backward.
