[0046] As shown in Figures 1-3As shown, the workbench 102 is provided with a first scale line (not shown) along the X-axis direction and a second scale line (not shown) along the Y-axis direction. When the first driving assembly 12 drives the first positioning member 13 to move along the X-axis direction, the first scale line can be directly referenced to quickly determine whether the preset position X0 is reached.

The combination of the second telescopic device 221 and the second telescopic rod 222 ensures the stability of the second positioning member 23 during movement, thereby reducing the shaking and deviation of the second positioning member 23 during movement, and thereby improving the reliability of the template positioning device.

[0048] In this embodiment, each first driving assembly 12 includes two first telescopic rods 122, and each second driving assembly 22 includes two second telescopic rods 222.

[0049] In some embodiments, the first telescopic device 121 can be a first cylinder, and the first telescopic rod 122 can be a first piston rod. The first piston rod in the first cylinder can reciprocate in the first cylinder. The first piston rod is connected to the first positioning member 13. The movement of the first piston rod drives the first positioning member 13 to move relative to the workbench 102 along the X-axis direction to reach the preset position X0. The second telescopic device 221 can be a second cylinder, and the second telescopic rod 222 can be a second piston rod.

[0050] As shown in Figures 1-3 , the first positioning mechanism 1 further comprises a first adjustment key assembly 14 and a first counter 11. The first adjustment key assembly 14 is communicatively connected to the first counter 11. The first counter 11 is communicatively connected to the first telescopic device 121. The first adjustment key assembly 14 is used to adjust the value of the first counter 11. The second positioning mechanism 2 further comprises a second adjustment key assembly 24 and a second counter 21. The second adjustment key assembly 24 is communicatively connected to the second counter 21. The second counter 21 is communicatively connected to the second telescopic device 221. The second adjustment key assembly 24 is used to adjust the value of the second counter 21. By adjusting the value of the first counter 11 through the first adjustment key assembly 14, the first counter 11 transmits the value to the first telescopic device 121. The first telescopic device 121 drives the first telescopic rod 122 to move and drives the first positioning member 13 to move along the X-axis to the preset position X0 by a specified distance. By adjusting the value of the second counter 21 through the second adjustment key assembly 24, the second counter 21 transmits the value to the second telescopic device 221. The second telescopic device 221 drives the second telescopic rod 222 to move and drives the second positioning member 23 to move along the Y-axis to the preset position Y0 by a specified distance. This not only improves the accuracy of positioning, but also simplifies the operation process, improves the efficiency of proofing, and ensures the reliability of the sample positioning device.

[0051] As shown in Figures 1-4 , the first adjustment key assembly 14 comprises a first increase button 141 and a first decrease button 142. The first increase button 141 can increase the value of the first counter 11. The first decrease button 142 can decrease the value of the first counter 11.

The second decrease button 242 can decrease the value of the second counter 21. Simple button operation simplifies the operation process, ensuring efficient and accurate proofing work.

[0052] Specifically, pressing the first increase button 141 makes the value on the first counter 11 increase to a preset value, the first positioning member 13 moves forward along the X-axis direction by a distance of the preset value, pressing the first decrease button 142 makes the value on the first counter 11 decrease to the preset value, the first positioning member 13 moves reversely along the X-axis direction by a distance of the preset value. Pressing the second increase button 241 makes the value on the second counter 21 increase to a preset value, the second positioning member 23 moves forward along the Y-axis direction by a distance of the preset value, pressing the second decrease button 242 makes the value on the second counter 21 decrease to the preset value, the second positioning member 23 moves reversely along the Y-axis direction by a distance of the preset value, which improves the flexibility and convenience of the positioning of the template positioning device.

[0053] As shown in Figure 4 The first positioning mechanism 1 further comprises a first position detection member 15, which is in communication connection with the first counter 11 and is used for detecting the moving distance of the first positioning member 13. The first positioning mechanism 1 further comprises a second position detection member (not shown in the figure), which is in communication connection with the second counter 21 and is used for detecting the moving distance of the second positioning member 23. The reliability of the positioning is improved, and the deviation can be found and adjusted in time.

[0054] Specifically, the first position detection member 15 can detect the moving distance of the first positioning member 13 in real time and feed back the moving data to the first counter 11. When the preset value on the first counter 11 is consistent with the moving data fed back by the first position detection member 15, the first positioning member 13 reaches the preset position X0 and stops moving. The second position detection member can detect the moving distance of the second positioning member 23 in real time and feed back the moving data to the second counter 21. When the preset value on the second counter 21 is consistent with the moving data fed back by the second position detection member, the second positioning member 23 reaches the preset position Y0 and stops moving.

[0055] The first position detection member 15 and the second position detection member are both infrared distance sensors, the first position detection member 15 is arranged on the first telescopic device 121, and the second position detection member is arranged on the second telescopic device 221. The non-contact measurement mode avoids the wear and interference caused by the direct contact between the position detection member and the positioning member, effectively prolongs the service life of the template positioning device, and ensures the stability and reliability of the moving data acquisition.

[0056] In the embodiment, as Figures 1-4As shown, the template positioning device comprises two first driving assemblies 12 and two second driving assemblies 22, two output ends of the two first driving assemblies 12 are connected with two ends of the first positioning member 13 respectively, and two output ends of the two second driving assemblies 22 are connected with two ends of the second positioning member 23 respectively. It is ensured that the first positioning member 13 does not tilt or jam when moving along the X-axis direction, and the second positioning member 23 does not tilt or jam when moving along the Y-axis direction, the stability of movement is ensured, and the positioning accuracy is improved.

[0057] In other embodiments, the number of the first driving assemblies 12 in the template positioning device can be three, four, five, etc., and similarly, the number of the second driving assemblies 22 can be three, four, five, etc., which is not specifically limited here.
