The movable seat 4 can move longitudinally (for example, can move longitudinally through the cooperation of a guide rail and a sliding block) and is arranged at the position of the frame 1 corresponding to the two lateral sides of the plate-shaped object placing frame 2. Here, the length direction of the upper spacer bars 22 of the plate-like object placing frame 2 is taken as the transverse direction, and the interval direction between the upper spacer bars 22 of the plate-like object placing frame 2 is taken as the longitudinal direction; the first driving device 100 is configured to drive the moving seat 4 to perform the longitudinal movement. It should be noted that, when the first driving device 100 is a telescopic cylinder, a linear motor, a servo motor, or the like, and is a telescopic cylinder or a linear motor, a linear reciprocating end (such as a piston rod) of the first driving device is connected to the moving seat 4 directly or through a connecting piece, and drives the moving seat 4 to reciprocate longitudinally. In the case of a servo motor, the first driving device 100 may be connected to the movable seat 4 through the screw 41, and as to how the first driving device 100 is connected to the movable seat 4 through the screw 41, the description thereof will not be repeated; the tightness adjusting mechanism 5 is arranged on the movable seat 4 and can move along with the movable seat 4, and is used for adjusting the tightness of the positioning spacer rod nut 23 of the plate-shaped object placing frame 2 so as to lock and unlock the linkage plate 21; the clamping mechanism 6 is arranged on the movable seat 4 and can move along with the movable seat 4, and is used for clamping and releasing the linkage plates 21, and after the tightness adjusting mechanism 5 releases the locking of the positioning spacing rod nuts 23 on the linkage plates 21, the clamping mechanism 6 can drive the clamped linkage plates 21 to longitudinally move under the driving of the movable seat 4 so as to adjust the spacing between the corresponding upper spacing rods 22; the measuring mechanism is used for detecting the positions of a plurality of positioning spacer rod nuts 23 of the plate-shaped object placing frame 2; the control system (not shown) determines whether the spacing between the upper spacer bars 22 meets the requirement according to the position information of the positioning spacer bar nuts 23 detected by the measuring mechanism, if not, the first driving device 100, the tightness adjusting mechanism 5 and the clamping mechanism 6 are driven to do the corresponding actions.

When the sensor 71 needs to sense the position of the positioning spacer nut 23, the seventh driving device 700 drives the sensor 71 to move laterally to a position with a desired distance from the positioning spacer nut 23, so that the positioning spacer nut 23 can be detected when the sensor 71 moves longitudinally with the moving seat 4.

It should be noted that the sensor 71 may also share the second traverse table 51 with the electric batch 52 (e.g. mounted on the pivot block 54), so that the seventh driving means 700 need not be provided. Of course, an embodiment may be adopted in which the side plate 42 is extended with a support plate 43 at a position corresponding to the upper portion of the electric batch 52, the seventh driving device 700 is mounted on the support plate 43, and the driving end of the seventh driving device 700 is connected to the sensor 71, so that the seventh driving device 700 can drive the sensor 71 to move laterally.
