The side of the rod 9 to be measured is abutted so that each alignment component 20 pushes the rod 9 to be measured to move until the rod 9 to be measured extends along the first preset direction; the camera 31 and the controller, the camera of the camera 31 is set toward the rod 9 to be measured, and the camera 31 is set to be movable back and forth along the first preset direction, so that after the rod 9 to be measured extends along the first preset direction, the camera 31 moves to the recording position to shoot the rod 9 to be measured; wherein, the camera 31 is communicatively connected to the controller so that the controller obtains the length of the rod 9 to be measured based on the shooting results of the camera 31.

[0031] The measuring device of the present invention includes a frame 10, an alignment component, a camera 31 and a controller. When the rod 9 to be measured is mounted on the placement slot 11, the rod 9 to be measured will be inclined at a certain angle relative to the first preset direction. The two alignment components 20 move toward each other along the second preset direction until at least part of the end face of each alignment component 20 abuts against the side of the rod 9 to be measured, so that each alignment component 20 pushes the rod 9 to be measured to move until the rod 9 to be measured extends along the first preset direction, ensuring that the extended length of the rod to be measured along the first preset direction is the length to be measured; then the camera 31 moves along the first preset direction to the input position to photograph the rod 9 to be measured, and the photos taken by the camera 31 are fed back to the controller. The controller compares the photos with the reference model in the database to determine the current length of the rod 9 to be measured. The user no longer needs to accurately measure the rod 9 to be measured, and can quickly obtain the length of the rod 9 to be measured, thereby solving the problem of low length measurement efficiency of crystalline silicon square rods in the prior art.

[0032] Specifically, the rod 9 to be measured is a crystalline silicon square rod. Since the production standard of the crystalline silicon square rod is determined, the controller can compare the photo with the reference model in the database to determine the length of the current rod 9 to be measured; the first preset direction is as follows: Figure 2 The horizontal direction shown in , the second preset direction is as Figure 2 The vertical direction shown in ; the imaging component 31 is a camera.

[0033] In this embodiment, if Figures 1 to 4As shown, each alignment component 20 includes a first mounting plate 21 and a plurality of first rollers 22, the first mounting plate 21 extends along a first preset direction, and the plurality of first rollers 22 are arranged on the first mounting plate 21 at intervals along the first preset direction, the axis of each first roller 22 extends along a vertical direction, and the two first mounting plates 21 are movably arranged toward each other along a second preset direction, so that the circumferential side surfaces of at least part of the first rollers 22 of each alignment component 20 abut against the circumferential side surfaces of the rods 9 to be measured; wherein the first preset direction, the second preset direction and the vertical direction are arranged perpendicular to each other; when the camera 31 moves to the recording position, the camera 31 can capture all the rods 9 to be measured.

[0034] Specifically, the rod 9 to be measured has a first circumferential side surface 91 and a second circumferential side surface 92 arranged opposite to each other along a second preset direction. The two first mounting plates 21 are used to drive the plurality of first rollers 22 thereon to move toward each other along the second preset direction until the circumferential side surface of a portion of the first rollers 22 on one first mounting plate 21 abuts against the first circumferential side surface 91, and the circumferential side surface of a portion of the first rollers 22 on the other first mounting plate 21 abuts against the second circumferential side surface 92. Then, the two first mounting plates 21 continue to move toward each other along the second preset direction, so that the portion of the first rollers 22 on the two first mounting plates 21 pushes the rod 9 to be measured, causing the rod 9 to swing until the extension direction of the rod 9 to be measured is parallel to the first preset direction. At this time, the circumferential side surfaces of all the first rollers 22 on each first mounting plate 21 abut against the circumferential side surface of the rod 9 to be measured, so that the rod 9 to be measured continues to extend along the first preset direction.

[0035] In this embodiment, if Figures 1 to 4 As shown, each alignment component 20 also includes a second mounting plate 23, two first connecting plates 24 and a first slider 25. Each first connecting plate 24 extends in a vertical direction. The two first connecting plates 24 are respectively arranged on both sides of the first mounting plate 21 along a first preset direction. One side of each first connecting plate 24 is connected to the first mounting plate 21, and the other side of each first connecting plate 24 is connected to the second mounting plate 23. The first slider 25 is arranged on the second mounting plate 23, and the first slider 25 is movably arranged along the second preset direction.

[0036] Specifically, the first connecting plate 24 is used to connect the first mounting plate 21 and the second mounting plate 23 , so that the first sliding block 25 can drive the first mounting plate 21 to move along the second preset direction through the second mounting plate 23 .

[0037] In this embodiment, if Figures 1 to 4As shown, the alignment assembly also includes a first slide rail 26 and a first driving member 27. The first slide rail 26 extends along a second preset direction. The first slider 25 of each alignment component 20 is movably mounted on the first slide rail 26. The first slider 25 of each alignment component 20 is driven and connected to the first driving member 27 to drive the first sliders 25 of the two alignment components 20 to move toward each other on the first slide rail 26.

[0038] Specifically, by cooperating with the first slider 25 and the first slide rail 26, the first slide rail 26 can guide the first mounting plate 21 to prevent the movement direction of the first mounting plate 21 from deviating from the second preset direction; the first driving member 27 is used to drive the first slider 25 to move, so that the first slider 25 can drive the first mounting plate 21 to move.

[0039] Optionally, the first driving member 27 is a cylinder.

[0040] In this embodiment, if Figure 5 As shown, the measuring device also includes a first clamping assembly, which includes two first clamping plates 41 arranged opposite to each other along a second preset direction, and a plurality of second rollers 42 are provided on the side of each first clamping plate 41 close to the rod 9 to be measured, and the plurality of second rollers 42 are arranged on the first clamping plate 41 at intervals along the vertical direction, and the two first clamping plates 41 are movably arranged toward each other along the second preset direction, so that the second rollers 42 on the two first clamping plates 41 respectively abut against the two circumferential side surfaces of the rod 9 to be measured, so that the two first clamping plates 41 clamp one end of the rod 9 to be measured; wherein the axial direction of each second roller 42 is arranged parallel to the first preset direction.

[0041] Specifically, the two first clamping plates 41 move toward each other along the second preset direction, so that the second rollers 42 on the two first clamping plates 41 respectively abut against the first circumferential side surface 91 and the second circumferential side surface 92 of the rod 9 to be measured, so that the two first clamping plates 41 clamp one end of the rod 9 to be measured, so that the first clamping assembly can further fix the rod 9 to be measured, so that the rod 9 to be measured remains extended along the first preset direction, thereby ensuring the measurement accuracy of the length of the rod 9 to be measured.

[0042] In this embodiment, if Figure 1 As shown, the measuring device also includes a limit plate 50, which extends along the second preset direction. Along the first preset direction, the limit plate 50 is arranged on the side of the rod 9 to be measured close to the first clamping assembly, and at least part of the first clamping plate 41 is arranged above the limit plate 50. The limit plate 50 is used to abut against the first axial end face of the rod 9 to be measured to limit the rod 9 to be measured.

[0043] Specifically, by abutting the first axial end face of the rod 9 to be measured with the limit plate 50, the limit plate 50 can limit the rod 9 to be measured in the first preset direction, thereby preventing the rod 9 to be measured from moving along the first preset direction to leave the shooting range, causing the camera 31 to need to move a longer distance to reach the recording position, thereby affecting the measurement efficiency of the measuring device.

[0044] In this embodiment, if Figure 6 As shown, the measuring device also includes a second clamping assembly. Along the first preset direction, the first clamping assembly and the second clamping assembly are respectively arranged on both sides of the rod 9 to be measured.

The two second clamping plates 62 are movably arranged toward each other along the second preset direction, so that each clamping pad 63 on the two second clamping plates 62 respectively abuts against the two circumferential side surfaces of the rod 9 to be measured, so that the two second clamping plates 62 clamp the other end of the rod 9 to be measured.

[0045] Specifically, after the rod 9 to be measured is adjusted to extend along the first preset direction, after the limit plate 50 abuts against the first axial end face of the rod 9 to be measured, the two first clamping plates 41 clamp the other end of the rod 9 to be measured, and the support frame 61 moves with the second clamping component along the first preset direction, so that the two second clamping plates 62 move to above the other end of the rod 9 to be measured, and then the two second clamping plates 62 move toward each other along the second preset direction, so that the respective clamping pads 63 on the two second clamping plates 62 abut against the first circumferential side surface 91 and the second circumferential side surface 92 of the rod 9 to be measured, respectively, so that the second clamping component can clamp the other end of the rod 9 to be measured, so that the second clamping component can further fix the rod 9 to be measured, so that the rod 9 to be measured keeps extending along the first preset direction, thereby ensuring the measurement accuracy of the length of the rod 9 to be measured.

[0046] In this embodiment, if Figure 6 As shown, the second clamping component also includes a second driving member 64 and a third mounting plate 65. The third mounting plate 65 is connected to the support frame 61. The second driving member 64 is arranged on the side of the third mounting plate 65 close to the rod 9 to be measured. The two second clamping plates 62 are respectively arranged on both sides of the second driving member 64. Each second clamping plate 62 is driven and connected to the second driving member 64 so that the second driving member 64 drives the two second clamping plates 62 to move; wherein, the second driving member 64 is located above the rod 9 to be measured.

[0047] Specifically, the third mounting plate 65 is used to connect the support frame 61 and the second clamping component, so that the second clamping component can move with the support frame 61; the second driving member 64 is used to drive each second clamping plate 62 to move; the second driving member 64 is located above the rod to be measured 9, which can avoid interference between the second driving member 64 and the rod to be measured 9 when the second clamping component moves along the first preset direction, resulting in the respective clamping pads 63 on the two second clamping plates 62 being unable to abut against the two circumferential sides of the rod to be measured 9, thereby ensuring that the second clamping member can smoothly clamp the other end of the rod to be measured 9.

[0048] In this embodiment, as shown in Figure 8, the measuring device also includes a pushing component, which includes a support plate 71 and a pushing plate 72. The pushing component is arranged on the side of the rod 9 to be measured away from the first clamping assembly, and the pushing plate 72 is arranged on the support plate 71. The support plate 71 is movably arranged along the first preset direction so that the pushing plate 72 abuts against the second axial end face of the rod 9 to be measured, so that the pushing plate 72 pushes the rod 9 to be measured to move along the first preset direction until the limit plate 50 abuts against the first axial end face of the rod 9 to be measured.

[0049] Specifically, after the rod 9 to be measured is adjusted to extend along the first preset direction, the support plate 71 drives the pushing plate 72 to move along the first preset direction, so that the pushing plate 72 abuts against the second axial end face of the rod 9 to be measured, and then the pushing plate 72 pushes the rod 9 to be measured to move along the first preset direction until the limit plate 50 abuts against the first axial end face of the rod 9 to be measured, so that the two first clamping plates 41 clamp and fix one end of the rod 9 to be measured; then the support frame 61 starts to drive the second clamping component to move, so that the two second clamping plates 62 clamp and fix the other end of the rod 9 to be measured.

[0050] Specifically, the pushing component also includes an adsorption component 77, which is arranged on the support plate 71. The suction cup 771 of the adsorption component 77 passes through the support plate 71 and the pushing plate 72 to be adsorbed and connected with the second axial end face of the rod 9 to be measured. Such an arrangement ensures the reliability of the connection between the pushing component and the rod 9 to be measured, and ensures that the pushing component can drive the rod 9 to be measured to move.

[0051] In this embodiment, if Figure 7 As shown, the measuring device also includes a camera assembly, which includes a protective cover 32, a second slider 33, a second slide rail 34 and a camera element 31. The second slide rail 34 is arranged on the frame 10, and the camera element 31 is arranged in the protective cover 32. The protective cover 32 is arranged on the second slider 33. The second slide rail 34 extends along a first preset direction. The second slider 33 is movably mounted on the second slide rail 34 so that the second slider 33 drives the protective cover 32 to move, so that the camera element 31 moves to the recording position.

[0052] Specifically, the protective cover 32 is used to protect the camera 31 and is also used to connect the second slider 33 and the camera 31, ensuring that the second slider 33 can drive the camera 31 to move along the first preset direction through the protective cover 32; through the cooperation between the second slider 33 and the second slide rail 34, the second slide rail 34 can guide the camera 31 to prevent the movement direction of the camera 31 from deviating from the first preset direction.

[0053] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0054] The measuring device of the present invention includes a frame 10, an alignment component, a camera 31 and a controller. When the rod 9 to be measured is mounted on the placement slot 11, the rod 9 to be measured will be inclined at a certain angle relative to the first preset direction. The two alignment components 20 move toward each other along the second preset direction until at least part of the end face of each alignment component 20 abuts against the side of the rod 9 to be measured, so that each alignment component 20 pushes the rod 9 to be measured to move until the rod 9 to be measured extends along the first preset direction, ensuring that the extended length of the rod to be measured along the first preset direction is the length to be measured; then the camera 31 moves along the first preset direction to the input position to photograph the rod 9 to be measured, and the photos taken by the camera 31 are fed back to the controller. The controller compares the photos with the reference model in the database to determine the current length of the rod 9 to be measured. The user no longer needs to accurately measure the rod 9 to be measured, and can quickly obtain the length of the rod 9 to be measured, thereby solving the problem of low length measurement efficiency of crystalline silicon square rods in the prior art.

[0055] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures.
