In order to meet the requirements of placing and protecting the plate-shaped objects with different specifications, the steps are convenient to carry out, and the working efficiency is improved. The applicant has invented a plate-shaped object placing rack (corresponding patent application No. 2019215084811), as shown in fig. 1, the rack body has four guide connecting rods which are parallel to each other and distributed in a rectangular shape, a placing area is formed between the four guide connecting rods, a plurality of linkage plates which are one-to-one corresponding and can move longitudinally along the guide connecting rods are movably installed between the upper and lower guide connecting rods at two transverse sides through guide blocks, respectively, upper spacing rods are connected between the tops of the linkage plates which are transversely opposite, lower spacing rods which are located between two adjacent upper spacing rods in the longitudinal direction are connected between the lower parts of the linkage plates which are transversely opposite, a plurality of transversely distributed and one-to-one corresponding spacing grooves are arranged on two longitudinally adjacent upper spacing rods, a spacing space which can be penetrated by a plate-shaped object is formed between the two corresponding spacing grooves, and a positioning spacing rod nut (i.e. a locking piece) is used for adjustably locking the linkage plates to, after the locking of the positioning spacing rod nuts on the linkage plates is released, the intervals between the upper spacing rods and between the lower spacing rods can be adjusted by moving the intervals between the linkage plates, so that the placing requirements of plate-shaped objects with different specifications are met. When the plate-shaped object placing rack works, the bottom ends of the plate-shaped objects are supported (or supported) by the lower spacing rods, so that the plurality of plate-shaped objects can be stably placed on the placing rack at intervals and can be conveniently taken and placed through the limiting and supporting of the two sides and the bottom; the plate-shaped objects are not contacted with each other, so that each plate-shaped object is kept in an independent state of being only contacted with the upper spacing rod and the lower spacing rod, materials in the processes of grinding, edge milling, cleaning, tempering, spraying and the like in the production process of the plate-shaped objects (such as glass) are convenient to transfer and accurately position when the plate-shaped objects are taken and placed, the smooth operation of the work is not influenced, the plate-shaped objects do not need to be taken to a specific placing tool, and the processed plate-shaped objects are not polluted and damaged; meanwhile, the positions of the upper and lower spacing rods can be adjusted by moving the position of the linkage plate, and the width of the limiting space is changed by the position, so that the use requirements of plate-shaped objects with different specifications are met, and the application range of the plate-shaped objects is greatly improved.

the movable seat 4 can be longitudinally moved (for example, can be longitudinally moved by matching a guide rail with a sliding block) and is arranged at the position of the machine frame 1 corresponding to the two transverse sides of the plate-shaped object placing frame 2. It should be noted that, here, the length direction of the upper spacing bars 22 of the plate placing rack 2 is taken as the transverse direction, and the spacing direction between the upper spacing bars 22 of the plate placing rack 2 is taken as the longitudinal direction; the first driving device 100 is used for driving the movable base 4 to make the longitudinal movement. It should be noted that the first driving device 100 is a telescopic cylinder, a linear motor, a servo motor, or the like, and when the first driving device is a telescopic cylinder or a linear motor, a linear reciprocating end (e.g., a piston rod) of the first driving device is connected to the movable base 4 directly or through a connecting member, and drives the movable base 4 to reciprocate longitudinally. In the case of a servo motor, the first driving device 100 may be connected to the movable base 4 through the lead screw 41, and how the first driving device 100 is connected to the movable base 4 through the lead screw 41 is the prior art and is not described herein again; 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 a 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 plate 21, and when the tightness adjusting mechanism 5 unlocks the linkage plate 21 by the positioning spacer bar nut 23, the clamping mechanism 6 can drive the clamped linkage plate 21 to longitudinally move under the driving of the movable seat 4 so as to adjust the distance between the corresponding upper spacer bars 22; the measuring mechanism is used for detecting the positions of a plurality of positioning spacing rod nuts 23 of the plate-shaped object placing frame 2; the control system (not shown) judges whether the distance between the upper spacing rods 22 meets the requirement or not according to the position information of the positioning spacing rod nuts 23 detected by the measuring mechanism, and if not, drives the first driving device 100, the tightness adjusting mechanism 5 and the clamping mechanism 6 to perform the corresponding actions.

More specifically, the second traverse table 51 is provided with a pivot base 54 between the rotary head 521 and the positioning spacer rod nut 23, and the nut sleeve 53 is pivotally mounted on the pivot base 54 and detachably connected to the rotary head 521, so as to facilitate replacement of the nut sleeve 53 of a corresponding specification according to a different specification of the positioning spacer rod nut 23.

Specifically, the moving seat 4 is further provided with a seventh driving device 700 (which may be a telescopic cylinder or a telescopic motor), and the sensor 71 is connected to a driving end of the seventh driving device 700, so that the seventh driving device 700 can drive the sensor 71 to perform a transverse movement. When the sensor 71 needs to sense the position of the spacer bar nut 23, the seventh driving device 700 can drive the sensor 71 to move transversely to a position where the transverse distance from the spacer bar nut 23 is at a required value, so that the spacer bar nut 23 can be detected when the sensor 71 moves longitudinally along with the movable base 4.

It should be noted that the sensor 71 may also share the second traverse table 51 (e.g., mounted on the pivot mount 54) with the electric batch 52, thereby eliminating the need for the seventh driving device 700. Of course, an embodiment may also be adopted, in which a support plate 43 extends from the side plate 42 at a position above the electric screwdriver 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 with the sensor 71, so that the seventh driving device 700 can drive the sensor 71 to move transversely.
