Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a flat-lay centering and positioning stage for detecting the size of single-crystal silicon square rods. Background Technology

[0002] With the development of photovoltaic manufacturing technology, there is a demand for automated dimensional inspection of solar monocrystalline silicon rods. This technology aims to improve measurement accuracy and production efficiency, which in turn leads to the development of automated inspection devices based on mechanical positioning.

[0003] In related technologies, the initial method of manual measurement using vernier calipers had problems such as arbitrary operation and poor consistency; later, automatic positioning solutions represented by the V-shaped positioning and testing table for double beams emerged, realizing the initial mechanical positioning function.

[0004] However, the aforementioned automatic positioning and detection device still suffers from a small positioning contact area, insufficient positioning stability, and structural limitations that prevent it from being adapted to the detection of half-bar specification products, thus limiting its further application in production quality control systems. Utility Model Content

[0050] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0051] like Figures 1-6 The accompanying drawing shows a schematic diagram of the structure of a flat-type centering and positioning stage for detecting the size of a single-crystal silicon square rod according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0052] This application provides a flat-lay centering and positioning stage for detecting the size of single-crystal silicon square rods, including a support assembly 100, a transmission assembly 200, a drive assembly 300, and a clamping assembly 400.

[0053] In some embodiments, the support assembly 100 constitutes the basic support structure of the entire device, including a base 110, on which a test platform 150 is fixed on both sides of the top of the base 110, and a test platform 160 for supporting the test piece 500 is installed on the test platform 150; at the same time, a positioning hole 170 is provided on the test platform 160.

[0054] Furthermore, a lifting cylinder 120 is installed in the middle of the base 110. The output end of the lifting cylinder 120 extends vertically upward through the base 110 and is connected to a lifting plate 130. Guide shafts 140 are respectively provided at the four corners of the bottom of the lifting plate 130 in the vertical direction. The guide shafts 140 cooperate with the guide holes on the base 110 to ensure that the lifting plate 130 can be raised and lowered smoothly in the vertical direction, thereby adapting to test pieces 500 of different heights.

[0055] In some embodiments, the drive assembly 300 is installed at the middle position of the lifting plate 130, and includes a cylinder seat 310 fixed on the lifting plate 130, on which a dual-output cylinder 320 is mounted. The output ends on both sides of the dual-output cylinder 320 are respectively connected to a connector 340 via connecting rods 330.

[0056] In some embodiments, the transmission components 200 are symmetrically arranged on both sides of the lifting plate 130;

[0057] Furthermore, each transmission component 200 includes a housing 210, inside which a rotatable shaft 250 is disposed, and a first gear 240 and a second gear 260 are fixedly fixed along the axial direction on the shaft 250; the first gear 240 meshes with a horizontally disposed first rack 230, and the end of the first rack 230 away from the first gear 240 is fixedly connected to the connector 340 of the drive component 300; the two sides of the second gear 260 are respectively meshed with a second rack 270 and a third rack 280, and the second rack 270 and the third rack 280 can move towards or away from each other in the horizontal direction, and a clamping plate 220 is fixedly installed at the ends of the second rack 270 and the third rack 280 away from the second gear 260;

[0058] Furthermore, a positioning pin 290 is added to the top of the housing 210, and the positioning pin 290 matches the positioning hole 170 in the height direction;

[0059] When the lifting cylinder 120 moves upward, the positioning pin 290 is inserted into the positioning hole 170 on the testing table 160 to ensure that the entire transmission assembly 200 and the corresponding clamping assembly 400 do not shift left or right in the horizontal direction.

[0060] In some embodiments, the clamping assembly 400 is used to directly clamp and fix the test piece 500, and includes a first clamping rod 410 and a second clamping rod 420.

[0061] Furthermore, the bottoms of the first clamping rod 410 and the second clamping rod 420 respectively cooperate with the corresponding clamping plates 220 in the transmission assembly 200, and the tops are equipped with clamping arms 430 for contacting the workpiece.

[0062] It is understandable that, in order to ensure the parallelism and stability of the clamping, an eccentric shaft 440 is provided at the connection between the first clamping rod 410 and the clamping arm 430.

[0063] Correspondingly, a pressure cap 450 is provided at the connection between the second clamping rod 420 and the clamping arm 430. By adjusting the eccentric shaft 440, it can be ensured that the two clamping arms 430 remain parallel during the clamping process.

[0064] The working process of this utility model is as follows:

[0065] The test piece 500 is placed flat on the testing table 160. The lifting cylinder 120 changes the vertical position of the lifting plate 130 so that the clamping assembly 400 is adapted to the height of the test piece 500.

[0066] The double-output-shaft cylinder 320 of the drive assembly 300 is activated, which pushes the first rack 230 in the two transmission assemblies 200 to move horizontally through the connecting rod 330 and the connector 340; the first rack 230 drives the first gear 240 to rotate, which in turn drives the second gear 260 to rotate synchronously through the rotating shaft 250; the second gear 260 drives the second rack 270 and the third rack 280 to move synchronously towards each other, thereby pushing the first clamping rod 410 and the second clamping rod 420 of the clamping assembly 400 to move closer to each other through the clamping plate 220, and finally causing the clamping arm 430 to clamp the workpiece 500 to be tested;

[0067] After the inspection is completed, the dual-output shaft cylinder 320 reverses its movement, causing the transmission component 200 to move in the opposite direction, the clamping component 400 to release, and the workpiece to be removed.

[0068] In summary, the present invention has a reasonable structure. It uses a flat testing platform 160 for support, and works in conjunction with the drive assembly 300 and the transmission assemblies 200 on both sides for synchronous clamping. This increases the contact area with the test piece 500, avoids the problems of small positioning contact points and easy shaking in related technologies, and significantly improves positioning stability.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
