[0025] The present invention controls the driving module through a control system, and the image information collected by the camera 4 is transmitted back to the control system and is analyzed and processed by the software.

[0026] The working principle of the present invention is as follows:

[0027] First, the untreated sample is spread flat on the upper surface of the inspection plate, and then the driving module drives the clamping device 12 to move in the XYZ axis to drive the marking pen 9 to mark the surface of the sample. After marking several marking points on the sample surface in turn, the camera 4 collects the distance between several marking points on the sample, and then the sample is taken for processing. The processed sample is spread on the upper surface of the inspection plate again, and then the camera 4 collects the distance between several marking points on the sample again. The software calculates the change rate and change amount of the distance between the marking points on the sample before and after twice to determine the dimensional stability of the sample.

[0028] Compared with the prior art, the present invention uses automated dotting and measurement, and the results are calculated by software, which effectively reduces labor costs, saves time, and can meet the measurement of different sizes with high work efficiency.

[0029] The workbench 1 further includes a bracket 8 , which is disposed at the upper end of the workbench 1 , and the camera 4 is fixed on the bracket 8 .

[0030] In this embodiment, a clamping device 10 is also included, and the clamping device 10 is connected to the driving end of the driving module. The clamping device 10 includes a first cylinder 101 and a clamping block 102. The first cylinder 101 is drivingly connected to the clamping block 102. The first cylinder 101 drives the clamping block 102 to move along the Z axis. A clamping plate 103 is provided at the bottom end of the clamping block 102. A slot 104 is provided on the clamping plate 103, and the slot 104 is slidably sleeved on the surface of the marker 9.

[0031] By adopting the above scheme, the driving module drives the clamping device 10 to move downward, and the first cylinder 101 drives the clamping block 102 to move downward, driving the clamping plate 103 to press downward on the sample surface. When the marker pen 9 makes a dot downward, it can effectively avoid moving the sample when the marker pen 9 makes a dot, causing errors in the measurement results.

[0032] In this embodiment, the clamping device 12 further includes a rotating mechanism 11 , a rotating driving end of the rotating mechanism 11 is drivingly connected to the pen clip seat 122 , and the rotating mechanism 11 drives the pen clip seat 122 to rotate.

[0033] Wherein, the rotating mechanism 11 is a rotating cylinder.

[0034] By adopting the above scheme, the pen clip holder 122 is driven to rotate by the rotating mechanism 11, which drives the marking pen 9 to rotate, and can simulate the action of a human hand rotating left and right when marking the sample, so that the mark of the marking pen 9 on the surface of the sample is clearer, which is conducive to the collection of image information by the camera 4. In addition, since a clamping device 10 is provided, it can prevent the marking pen 9 from dragging the sample when rotating.

[0035] In this embodiment, a pressing plate 7 and a driving device 5 are also included. The pressing plate 7 and the driving device 5 are arranged above the workbench 1, and the lower end of the pressing plate 7 is hinged to the detection plate 15. The driving device 5 is connected to the pressing plate 7 for driving. The driving device 5 drives the pressing plate 7 to flip so that the pressing plate 7 is pressed against the upper surface of the detection plate 15.

[0036] By adopting the above solution, by providing the pressing plate 7, when the sample is laid on the surface of the detection plate 15, the pressing plate 7 is turned over and pressed on the surface of the sample to flatten the sample, so that the measurement is more accurate.

[0037] In this embodiment, the driving device 5 includes a driving motor 50, a pay-off shaft 51, and a connecting wire 52. One end of the connecting wire 52 is connected to the upper end of the pressure plate 7, and the other end of the connecting wire 52 is connected to the pay-off shaft 51. The driving motor 50 is drivingly connected to the pay-off shaft 51. The driving motor 50 drives the pay-off shaft 51 to rotate, so that the pay-off shaft 51 can wind up or lengthen the connecting wire 52.

[0038] With the above solution, the driving motor 50 drives the pay-off shaft 51 to rotate, so that the pay-off shaft 51 can wind up or lengthen the connecting wire 52 to complete the flipping action of the pressing plate 7.

[0039] In this embodiment, a second cylinder 13 is also included. The second cylinder 13 fixes one side of the upper end of the pen clip holder 122, and the piston rod of the second cylinder 13 is arranged above the marker 9. The second cylinder 13 drives the piston rod to telescope, so that the piston rod knocks and squeezes the marker 9.

[0040] By adopting the above solution, the piston rod of the second cylinder 13 strikes and squeezes the marker pen 9, so that the paint inside the marker pen 9 flows out smoothly.

[0041] In this embodiment, a third cylinder 17 and a pen box 18 are also included. The pen box 18 is arranged above the workbench 1, and a marker 9 capable of marking different colors is provided on the pen box 18. The third cylinder 17 is arranged inside the workbench 1 and is drivingly connected to the pen box 18. The third cylinder 17 drives the pen box 18 to move along the Z axis.

[0042] By adopting the above scheme, the control system can select the marker pen 9 with the largest color contrast according to samples of different colors, so that the mark can be clearly displayed on the sample surface, that is, the control system controls the driving module to drive the clamping device 12 to move to the marker pen 9 of appropriate color, and then the control system controls the pneumatic clamp 121 to clamp the marker pen 9, and finally the control system controls the driving module to drive the clamping device 12 to move to the appropriate dotting position for dotting.

[0043] In this embodiment, it also includes a fourth cylinder 20, a cylinder seat 21, and a whiteboard box 19. The cylinder seat 21 is connected to the piston rod of the third cylinder 17. The fourth cylinder 20 is fixed on the cylinder seat 21 and is drivingly connected to the whiteboard box 19. The fourth cylinder 20 drives the whiteboard box 19 to move along the Z axis.

[0044] With the above scheme, the marker 9 is tapped on the whiteboard box 19 before marking, simulating a person holding the marker 9 and tapping on white paper, so that the solidified paint is removed and the paint inside slowly flows out of the pen clip, which is convenient for marking.

[0045] In this embodiment, a guide rail 161 is disposed at the upper end of the workbench 1 , and a slider is disposed at the lower end of the detection plate 15 . The slider is slidably sleeved on the surface of the guide rail 161 .

[0046] By adopting the above solution, the detection plate 15 can be slid out of the workbench 1 by sliding the slider on the surface of the guide rail 161 , so that the sample can be placed on the detection plate 15 conveniently.

[0047] The present invention further comprises a housing 14 , which covers the workbench 1 , and a surface of the housing 14 is provided with an opening 141 for the pressure plate 7 and the detection plate 15 to pass through.

[0048] In this embodiment, the driving module includes an X-axis driving module 3, a Y-axis driving module 2, and a Z-axis driving module 6.

The Z-axis driving module 6 is drivingly connected to the clamping device 12, and the Z-axis driving module 6 drives the clamping device 12 to move along the Z-axis.

[0049] By adopting the above scheme, the X-axis drive module 3 and the Y-axis drive module 2 are driven by servo motors, belts and transmission wheels, and the Z-axis drive module 6 is driven by a cylinder, so that the position of the dot is accurate, which is beneficial to the accuracy of measurement.

[0050] In this embodiment, a spring 124 is also included. The spring 124 is arranged at the upper end of the clamping device 10, and the spring 124 is sleeved on the surface of the piston rod of the second driving member. Through the buffering effect of the spring 124, the damage to the sample caused by the clamping device 10 and the marking pen 9 can be reduced to prevent the sample from deformation.
