[0039] Reference below Figure 1-Figure 5 The second dimension image measuring instrument according to the embodiment of the utility model is described.

[0040] like Figure 1-Figure 5 As shown, the two-dimensional image measuring instrument includes a frame 110, and the bottom of the frame 110 is provided with a support leg 130 and a plurality of rollers 120 for supporting a bracket. It also includes a working platform 200, a Y-axis moving mechanism 400, an X-axis moving mechanism 300, an imaging mechanism 500 and a control component 600.

[0041] The working platform 200 is fixedly arranged on the frame 110, and the surface of the working platform 200 is detachably covered with a float glass 210. The float glass 210 and the working platform 200 are sealed and connected by a sealing silicone (not shown in the drawings), and the float glass 210 and the working platform 200 are vacuumed. The existing working platform 200 often needs to assume the function of horizontal movement, and its bottom needs to be connected to the guide rail, so that the inside of the working platform 200 is connected to the outside world. During use, dust or foreign matter enters the inside of the working platform 200, which will affect the lighting effect of the internal lighting components of the working platform 200, resulting in shadows on the edge of the workpiece during the measurement process, affecting the measurement accuracy. In this embodiment, a sealing silicone is provided at the connection between the working platform 200 and the float glass 210, and the sealing silicone is pressed by the dead weight of the float glass 210, so that a sealed environment is formed inside the working platform 200. Since the working platform 200 is fixedly arranged, the vacuum environment inside the working platform 200 can be stably maintained. During the installation of the float glass 210, a vacuuming device is used to vacuumize the inside and then close the float glass 210. Make the internal light source shine evenly.

[0042] The Y-axis moving mechanism 400 is across the workbench, and the imaging mechanism 500 is slidably connected to the Y-axis moving mechanism 400, and the imaging mechanism 500 moves up and down toward the work platform 200. Specifically, the imaging mechanism 500 is a technical solution well known to those skilled in the art, and will not be described in detail in this embodiment. The imaging mechanism 500 is mainly composed of a Z-axis lifting structure and a CCD imaging structure. The Z-axis lifting structure drives the CCD imaging structure to focus and shoot the workpiece on the float glass 210 panel to obtain an image. The Y-axis moving mechanism 400 can adjust the horizontal position of the imaging mechanism 500 on the work platform 200.

Specifically, the two X-axis moving mechanisms 300 synchronously drive the two sides of the Y-axis moving mechanism 400 to realize the translation of the imaging mechanism 500 in the X-axis direction.

[0044] The control component 600 is arranged on one side of the working platform 200, and the control component 600 is electrically connected to the Y-axis moving mechanism 400, the imaging mechanism 500 and the X-axis moving mechanism 300 respectively. The staff can stand on one side of the working platform 200 to adjust the working state of the equipment through the control component 600. Compared with the external control device in the prior art, the overall structure height of the two-dimensional image measuring instrument of this embodiment is lower, the integration is higher, the operation is more stable, and the measurement accuracy is higher.

[0047] In a further embodiment, Figure 1 and Figure 2 As shown, dust covers 140 are respectively provided between the two sides of the Y-axis slide 420 and the side walls of the X-axis moving mechanism 300.

[0050] The two ends of the Y-axis base 410 are respectively connected to the X-axis slides 320 of the two X-axis moving mechanisms 300. The X-axis base 310 is provided with an X-axis screw motor, which is transmission-connected to the X-axis slides 320.

[0052] In a further embodiment, Figure 1 and Figure 2 As shown, dust covers 140 are respectively provided on both sides of the X-axis base 310. Specifically, the function of the dust cover 140 is the same as that of the dust cover 140 of the Y-axis moving mechanism 400, mainly to prevent the internal components of the X-axis moving mechanism 300 from being damaged.

[0053] In some embodiments of the present invention, Figure 2-Figure 4As shown, a leveling base 150 is arranged between the Y-axis base 410 and the X-axis slide 320, and the surface of the leveling base 150 is connected to the Y-axis base 410 by bolts, and the horizontal position of the Y-axis base 410 is adjusted by adding a gasket between the leveling base 150 and the Y-axis base 410.

[0054] Specifically, the bottom of the leveling base 150 is connected to the X-axis slide 320, and the top is connected to the Y-axis base 410. The vertical height of the Y-axis base 410 can be adjusted by adding a gasket on the leveling base 150.

[0056] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a detachable transparent window 330 is provided on the periphery of the X-axis moving mechanism 300, and the transparent window 330 is used to disassemble the leveling Y-axis moving mechanism 400. Specifically, the transparent window 330 is made of transparent acrylic material and is attached to the hollow part of the frame of the Y-axis moving mechanism 400 by screws or a magnetic structure. The staff can adjust the Y-axis base 410 by disassembling the transparent window 330, which is convenient for the staff to debug the equipment.
