Pulling the sliding bar structure 334 by the pressing elastic element 35 will make the abutting end 329 of the propping rod body 322 to be tightly leaned against the side 91 of the base plate 9.

Referring to fig. 4, in use, a plurality of clamping devices 1 are installed on a conveying device 4, the clamping devices 1 are respectively used for clamping a plurality of substrates 9 to perform a processing procedure, and the conveying device 4 includes a feeding port 41 for providing the substrates 9 and a discharging port 42 for discharging the substrates 9. The conveying device 4 can drive the clamping device 1 to the material inlet 41 to clamp the substrate 9 to be processed, and after corresponding processing steps, the substrate is moved to the material outlet 42 to send out the processed substrate 9.

Referring to fig. 4 and 5, when one of the clamping devices 1 has reached the material inlet 41 and the substrate 9 to be processed has also reached the material inlet 41, first, as exemplified by the substrate 9 with a larger area (e.g. 20x30cm), when the substrate 9 with a larger area is to be clamped, for the supporting mechanism 3 on the right side of the base 2, an operator or a robotic arm rotates the limiting rod 321 in the counterclockwise direction around the first fixed shaft 312 by operating the extending portion 324, for example, the second pivot end 326 of the limiting rod 321 links the front connecting structure 336 (see fig. 3) and the rear connecting structure 339, so that the front sliding structure 337 (see fig. 3) and the rear sliding structure 341 drive the sliding rod structure 334 to slide downwards along the sliding hole 317, and the front abutting structure 338 (see fig. 3) and the rear abutting structure 342 drive the contact structure 335 to rotate counterclockwise along the sliding hole 317 To abut against the side 91 of the substrate 9, i.e. the abutment end 329, to the first position, i.e. on the side of the support 31 adjacent to the substrate 9. Subsequently, the contact structure 335 is pressed against the side 91 of the substrate 9 by the elastic restoring force of the pressing elastic member 35. At the same time, the limiting rod 321 and the propping rod 322 of the left propping mechanism 3 are rotated clockwise in the same operation manner. Thereby, the abutting end portions 329 of the two abutting mechanisms 3 approach each other to tightly hold the substrate 9, so that the substrate 9 can be stably conveyed.

Referring to fig. 6, if the substrate 9 with a smaller area (e.g. 5 × 5cm) is to be clamped, the abutting end 329 can be further moved to abut against the side 91 of the substrate 9 from the first position shown in fig. 5, i.e. to the second position shown in fig. 6, i.e. on the side of the supporting frame 31 adjacent to the substrate 9 and closer to the other abutting mechanism 3 than the first position, for the abutting mechanism 3 on the right side of the base 2 in the same manner as described in the above paragraph. Subsequently, the contact structure 335 is pressed against the side 91 of the substrate 9 by the elastic restoring force of the pressing elastic member 35. At the same time, the limiting rod 321 and the propping rod 322 of the left propping mechanism 3 are rotated clockwise in the same operation manner. Thereby, the abutting end portions 329 of the two abutting mechanisms 3 approach each other to tightly hold the substrate 9, so that the substrate 9 can be stably conveyed.

Referring to fig. 4, fig. 7 and fig. 8, in another case, after each clamping device 1 places the substrate 9 from the discharging hole 42, for the propping mechanism 3 on the right side of the base 2, an operator or a robot arm, for example, operates the extending portion 324 to rotate the limiting rod 321 clockwise around the first fixed shaft 312, the second pivot end 326 of the limiting rod 321 links the front connecting structure 336 (see fig. 3) and the rear connecting structure 339, so that the front sliding structure 337 (see fig. 3) and the rear sliding structure 341 drive the sliding rod structure 334 to slide upwards along the sliding hole 317, and the front propping structure 338 (see fig. 3) and the rear propping structure 342 drive the contact structure 335 to rotate clockwise through the upper end 314 of the frame 311 to a third position as shown in fig. 7, in the third position, the limiting rod 321 provides a moment in a direction away from the base plate 9, and the pressing elastic element 35 provides the elastic restoring force to make the abutting end 329 continuously rotate in the clockwise direction, but since the limiting rod 321 abuts against the frame body 311 to limit the abutting end 329 from rotating in the clockwise direction relative to the supporting frame 31, and meanwhile, since the limiting rod 321 does not provide the moment in a direction toward the base plate 9 from the supporting rod 322, the abutting end 329 can be positioned in the third position and cannot rotate freely without any external force. At the same time, the limiting rod 321 and the propping rod 322 of the left propping mechanism 3 are rotated counterclockwise to the third position in the same operation manner. Thereby, the abutting ends 329 of the two abutting mechanisms 3 are far away from each other and positioned. By keeping the supporting mechanism 3 in the above state and moving toward the material inlet 41, and when one of the clamping devices 1 has reached the material inlet 41 but the substrate 9 to be processed has not yet reached the material inlet 41, the clamping device 1 does not perform the above-mentioned operation of rotating and clamping the substrate 9, thereby forming the state shown in fig. 8, ensuring that the clamping device 1 does not shake to knock or scratch the adjacent clamping devices 1 in front and back and the substrate 9 clamped by the clamping devices 1, and further improving the manufacturing yield of the substrate 9 in the manufacturing process.

To sum up, the clamping device 1 of the present invention utilizes the limiting rod 321 to rotate around the first fixing shaft 312, and the sliding end 328 of the propping rod 322 can slide up and down, and after the two are connected, the propping end 329 of the propping rod 322 can rotate relative to the supporting frame 31, thereby clamping the substrates 9 with different areas, and when the propping end 329 is respectively located on the two opposite sides of the supporting frame 31, the propping end 329 can clamp the substrate 9 tightly by the elastic restoring force of the pressing elastic member 35, or keep at the third position incapable of rotating, wherein, in the third position, the shaking caused by rotation can be avoided, further ensuring that the substrate 9 can not collide with the adjacent clamping device 1 or the substrate 9 clamped by the clamping device 1, thereby increasing the production yield of the substrate 9 in the manufacturing process, on the other hand, the single pressing elastic member 35 can achieve the effects of pressing and limiting respectively, thereby greatly reducing the production cost and achieving the purpose of practical utility model.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still within the scope of the present invention.
