[0015] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0016] Embodiment 1: A workpiece image measuring device comprises an image measuring instrument body 1, wherein two opposite sides of a worktable of the image measuring instrument body 1 are respectively mounted with a longitudinal linear motor 2, a fixed plate 23 is mounted on each of the two longitudinal linear motors 2 via a movable block, a plurality of parallel transverse linear motors 5 are mounted between the two fixed plates 23, so that the two fixed plates 23 can move synchronously along the direction of the longitudinal linear motor 2 with the movable block, a plurality of movable blocks respectively mounted on the transverse linear motor 5 are connected via a second mounting plate 6, and a plurality of support plates 12 for mounting a carrier 3 are spaced apart above the second mounting plate 6; A first mounting plate 4 is arranged between the carrier plate 3 and the second mounting plate 6, and a plurality of first pipe fittings 10 corresponding to the carrier plate 3 are arranged at intervals on the first mounting plate 4. A second pipe fitting 18 movable up and down is inserted at one end of the first pipe fitting 10 close to the carrier plate 3, and the top of each second pipe fitting 18 is provided with the support plate 12. A spring 9 in a compressed state is sleeved on the first pipe fitting 10 and the second pipe fitting 18, and the two ends of the spring 9 are respectively connected to the support plate 12 and the first mounting plate 4. The arrangement of the spring 9 means that after the workpiece is placed on the top of the carrier 3, the carrier 3 is affected by the gravity of the workpiece and moves downward, and the carrier 3 drives the second pipe 18 to slide inside the first pipe 10. At the same time, the carrier 3 applies pressure to the spring 9, and the length of the spring 9 is shortened by the force, and the spring 9 supports the carrier 3 by its own force, thereby reducing the gravity on the carrier 3. The first pipe 10 and the second pipe 18 are used to prevent the spring 9 from bending and deviating, thereby improving the ability of the spring 9 to stably contract or extend during the force application process. The first pipe 10 and the second pipe 18 are both hollow structures, which facilitates the gas pipe to sequentially pass through the first pipe 10, the second pipe 18 and the inner wall of the support plate 12 and be connected to the carrier 3, thereby improving the stability of the carrier 3 in adsorbing the workpiece. At least two grooves 11 are arranged at intervals on the side of the carrier 3, and a stud 20 corresponding to the groove 11 is arranged on the bottom surface of the support plate 12. A fixing block 7 is inserted into the inside of the groove 11, and a connecting plate 8 is welded to the side of the fixing block 7. A mounting groove 21 is opened at one end of the connecting plate 8, and a mounting block 22 is inserted into the inside of the mounting groove 21. A pressing plate 19 is welded on the surface of the mounting block 22, and one end of the pressing plate 19 is sleeved on the surface of the stud 20. A screw tube 13 is threadedly sleeved on the surface of the stud 20, and the top of the screw tube 13 contacts the bottom of the pressing plate 19. First, place the carrier plate 3 on the top of the support plate 12, insert the fixing block 7 into the groove 11, then sequentially sleeve the pressing plate 19 on the surface of the stud 20, and thread the screw 13 on the surface of the stud 20. By rotating the screw 13, the screw 13 is threadedly rotated on the surface of the stud 20 to push the pressing plate 19. As the pressing plate 19 moves, it is used to drive the mounting block 22 to be inserted into the mounting groove 21, and then the screw 13 can be stopped from rotating to complete the definition of the position of the connecting plate 8, thereby improving the stability of the carrier plate 3 placed on the top of the support plate 12; The second mounting plate 6 is respectively mounted with a solenoid valve 15, a vacuum filter 16 and a vacuum generator 17. The solenoid valve 15 is connected to the vacuum generator 17 via an air pipe, the vacuum generator 17 is connected to the vacuum filter 16 via an air pipe, and the vacuum filter 16 is respectively connected to a plurality of carriers 3 via air pipes. After placing the workpiece on the top of the carrier 3, first connect the solenoid valve 15, the vacuum filter 16 and the vacuum generator 17 to the switching power supply through a wire, then connect the switching power supply to the external power supply, and then manipulate the switching power supply to connect the solenoid valve 15, the vacuum filter 16 and the vacuum generator 17 to the power supply. After the solenoid valve 15, the vacuum filter 16 and the vacuum generator 17 are energized, the solenoid valve 15 opens as an outlet for gas circulation, and the vacuum generator 17 generates negative pressure to absorb the air between the carrier 3 and the workpiece, so that negative pressure is generated between the carrier 3 and the workpiece to firmly adsorb the workpiece and the carrier 3, and the vacuum filter 16 is used to filter out impurities in the air to avoid blockage of the gas pipe and improve the stability of the connection between the workpiece and the carrier 3.
