[0031] The following combination Figure 1-5 The fixing mechanism and processing equipment involved in the utility model are further explained.

[0032] Combine Figure 1-4 As shown, in one embodiment of a fixing mechanism 100, fixing mechanism 100 is used to fix a plate on a platform. Fixing mechanism 100 includes a negative pressure assembly and a clamping assembly 1. The negative pressure assembly is capable of applying a suction force to the plate through a through hole extending through the platform. The clamping assembly 1 is at least partially rotatable relative to the platform to cooperate with the platform to clamp the edge of the plate.

[0033] In this embodiment, a negative pressure component is provided to apply an adsorption force to the plate, and then under the rotating clamping action of the clamping component, it can be buckled on the plate, thereby cooperating with the platform to form an effect of clamping the edge of the plate, thereby solving the technical problem that the existing plate is prone to warping when fixed.

[0034] In this embodiment, specifically, the negative pressure component can be a vacuum generator, which uses the pressure difference to apply adsorption force to the plate by generating negative pressure, so that the plate can be adsorbed on the platform or the plate on the platform, which can reduce damage to the plate. In addition, it should be noted that the position of the negative pressure component can be set arbitrarily. The negative pressure component can be placed externally and connected to the through hole through an air pipe, or it can be directly set on the side of the platform away from the plate and directly connected through the hole.

[0035] In an embodiment of a fixing mechanism 100, the clamping assembly includes two first clamping assemblies 1, which are relatively arranged on both sides of the plate. At least parts of the two first clamping assemblies 1 can rotate relative to the platform so as to cooperate with the platform to clamp the opposite edges of the plate.

[0036] In this embodiment, two first clamping components 1 are provided to clamp the edges of the plate on both sides respectively, thereby achieving the technical effect of preventing the edges of the plate from warping on both sides, and further improving the effect of fixing the plate and balancing the forces on both sides of the plate.

[0037] In an embodiment of a fixing mechanism 100, the clamping assembly further includes at least one second clamping assembly 2, which is located between the two first clamping assemblies 1. The second clamping assembly 2 is at least partially rotatable relative to the platform to cooperate with the platform to clamp the edge of the plate.

[0038] In this embodiment, by further providing a second clamping assembly 2, a three-sided clamping and fixing effect can be achieved for the plate, further improving the fixing and anti-warping effects.

[0039] In an embodiment of a fixing mechanism 100, the fixing mechanism 100 also includes a first connecting part 4 and a second connecting part 5, wherein the two ends of one first clamping component 1 are respectively fixedly connected to the first connecting part 4 and the second connecting part 5, and the two ends of the other first clamping component 1 are respectively movably connected to the first connecting part 4 and the second connecting part.

[0040] In this embodiment, by fixing one of the two first clamping components 1 and setting the other to be movable, the distance between the two first clamping components 1 can be adjusted, so that plates of different sizes can be adapted, thereby improving the adaptability of the fixing mechanism 100.

[0041] In one embodiment of the fixing mechanism 100 , all second clamping assemblies 2 are disposed on the first connecting portion 4 . Alternatively, there are multiple second clamping assemblies 2 , with some of the multiple second clamping assemblies 2 disposed on the first connecting portion 4 and others on the second connecting portion 5 .

[0042] In this embodiment, the second clamping component 2 is arranged on the connecting part, which is conducive to forming a whole with the first clamping component 1 through the first connecting part 4. If both are arranged on the first connecting part 4, a three-sided clamping effect can be formed. When the second clamping component 2 is arranged on both the first connecting part 4 and the second connecting part 5, a four-sided clamping effect can be formed.

[0043] Specifically, there may be two second clamping assemblies 2 , one of which is provided on the first connecting portion 4 and the other of which is provided on the second connecting portion 5 .

[0044] In an embodiment of a fixing mechanism 100, the first connecting part 4 and the second connecting part 5 both include a slide rail 9 and a connecting piece, the slide rail 9 is arranged on the connecting piece, the two ends of the first clamping component 1 are respectively movably connected to the slide rail 9, and the second clamping component 2 is movably connected to the slide rail 9.

[0045] In this embodiment, specifically, the connecting member can be a plate-like structural member, and the first clamping component 1 and the second clamping component 2 are slidably connected by arranging a slide rail 9 thereon, thereby improving stability and avoiding grooving on the connecting member, and the slide rail 9 can also play a guiding role to improve movement accuracy.

[0046] In an embodiment of a fixing mechanism 100, the fixing mechanism 100 also includes a first fixing portion and a second fixing portion, the first fixing portion is installed on the first clamping component 1, and is used to fix the first clamping component 1 to the slide rail 9, and the second fixing portion is installed on the second clamping component 2, and is used to fix the second clamping component 2 to the slide rail 9.

[0047] In this embodiment, the first fixing portion and the second fixing portion are provided to fix the first clamping assembly 1 and the second clamping assembly 2 respectively, so that the positions of the first clamping assembly 1 and the second clamping assembly 2 can be adjusted and fixed conveniently.

[0048] Specifically, the fixing method is not limited. For example, the first fixing portion can be fixed by being engaged with the slide rail 9, or the first fixing portion can abut against the slide rail 9 to limit movement through friction to achieve a fixing effect.

[0049] In an embodiment of a fixing mechanism 100, a fixing hole 91 is opened on the slide rail 9 along its extension direction, and the first fixing part and the second fixing part both have a portion that can extend into the fixing hole 91, so that the first clamping component 1 can be fixed to the slide rail 9 and the second clamping component 2 can be fixed to the slide rail 9.

[0050] In this embodiment, the fixing is achieved by setting the fixing hole 91 in a snap-on manner. The first fixing portion and the second fixing portion can be configured as structural members that move relative to the first clamping assembly 1 and the second clamping assembly 2, such as rod-type and shaft-type structural members. After being moved to a position, they are fixed by being inserted into the fixing hole 91. Specifically, the first fixing portion can be a first knob 14, and the second fixing portion can be a second knob 24. The first knob 14 is movably connected to the first mounting seat of the first clamping assembly 1 by a thread. After the clamping assembly 1 slides to a suitable position, the first knob 14 is rotated to extend into the fixing hole 91, thereby achieving the fixation of the clamping assembly 1 to the slide rail 9. Similarly, the second knob 24 is also movably connected to the second clamping assembly 2 by a thread. After the clamping module 2 slides to a suitable position, the second knob 24 is rotated to extend into the fixing hole 91, thereby achieving the fixation of the clamping assembly 1 to the slide rail 9.

[0051] In one embodiment of the fixing mechanism 100, Figure 2 and Figure 3 As shown, the first clamping assembly 1 includes a driving member 11, a connecting shaft 12 and a plurality of clamping members 13. The output end of the driving member 11 is connected to the connecting shaft 12 and is used to drive the connecting shaft 12 to rotate. The plurality of clamping members 13 are installed on the connecting shaft 12 along the axial direction of the connecting shaft 12 so that they can abut against the edge of the plate under the rotation of the connecting shaft 12.

[0052] In this embodiment, by providing a plurality of clamping members 13 , the plate can be clamped at various locations along one edge of the plate, thereby achieving a better clamping and anti-warping effect.

[0053] Specifically, driven by the driving member 11 and driven by the connecting shaft 12, the clamping member 13 can be rotated from a vertical state to a horizontal state to abut and clamp the plate.

[0054] In an embodiment of a fixing mechanism 100, the second clamping assembly 2 includes a driving element 21 and a clamping module 23, the clamping module 23 includes a clamping unit 231, a rotating unit 232 and a fixing unit, and a strip hole 2311 is opened on the clamping unit 231. The fixing unit can be inserted into the strip hole 2311 to fix the clamping unit 231 and the rotating unit 231. The fixing unit can also move along the extension direction of the strip hole 2311 to adjust the position of the clamping unit 231 relative to the rotating unit 232. The output end of the driving element 21 is connected to the rotating unit 232 and is used to drive the rotating unit 232 to rotate.

[0055] In this embodiment, the clamping unit 231 and the rotating unit 232 are adjustable. The relative positions of the clamping unit 231 and the rotating unit 232 can be adjusted via the fixing unit. During adjustment, since the rotating unit 232 is connected to the output end of the driving element 21, the position of the rotating unit 232 can be maintained unchanged. The position of the clamping unit 231 relative to the rotating unit 232 can then be adjusted, facilitating the matching of different plate materials. Specifically, the extending direction of the strip-shaped hole 2311 is parallel to the axial direction of the connecting shaft 12.

[0056] Specifically, the fixing unit can be a bolt, and the extension direction of the strip hole 2311, that is, the length of the strip hole 2311, is greater than the diameter of the bolt. It can be understood that after the bolt is loosened, the relative movement position can be changed by moving the clamping unit 231 or moving the bolt. In this embodiment, the fixing unit can be loosened and the position of the fixing unit can be kept stationary. The clamping unit 231 can be moved to reposition the strip hole 2311 and the bolt and then tightened, thereby achieving the effect of adjusting the relative position of the clamping unit 231 and the rotating unit 232.

[0057] In addition, similarly, the clamping module 23 can also be rotated from a vertical state to a horizontal state under the drive of the driving element 21 to abut and clamp the plate.

[0058] More specifically, the clamping unit 231 and the rotating unit 232 can form a shape whose cross-section is converted between an inverted L-shape and a T-shape. The clamping unit 231 and the rotating unit 232 are respectively one side. It can be understood that when it is T-shaped, the extended length of the clamping unit 231 is short, and when it is L-shaped, the extended length of the clamping unit 231 is long, which can accommodate plates of different sizes.

[0059] In combination with the previous embodiments, it can be understood that the rotation angle of the clamping member 11 and the clamping element 21 is not fixed. For example, it can be rotated from vertical to horizontal, or from horizontal to horizontal. Different rotation angles can be set according to different shapes, and the preferred method is to contact the plate surface when finally abutting against the plate.

[0060] In combination with the previous embodiment, the clamping assembly 1 can also include a first mounting seat, on which the driving member 11, the connecting shaft 12, and the clamping member 13 can all be mounted. The first fixing member can also be mounted on the first mounting seat, or it can also be not mounted on the first mounting seat. For example, the first fixing member can be a shaft passing through a hole in the first mounting seat. After passing through the first mounting seat, the shaft can further pass into the fixing hole 91 to fix the first mounting seat to the slide rail 9. Similarly, the clamping module 2 can be provided with a second mounting seat, and the driving element 21, the rotating shaft 22, and the clamping element 23 can all be mounted on the second mounting seat. Similarly, a shaft that can pass through a hole in the second mounting seat is provided to achieve the effect of fixing to the slide rail 9. The first fixing portion is mounted on the first mounting seat, and the second fixing portion is mounted on the second mounting seat.

[0061] Further preferably, in addition to the driving member, the connecting shaft and the clamping member, the clamping assembly, such as the second clamping drill, may also be provided with a rotating shaft 22. In order to improve the stability of the rotation, components such as a coupling 8 may be further provided.

[0062] In one embodiment of the fixing mechanism 100, Figure 1-5 As shown, the fixing mechanism 100 also includes a support platform 6, which is placed on the platform. One end of the support platform 6 abuts against the first connecting part 4, and the other end abuts against the second connecting part 5. An adsorption hole connected to the through hole is also provided on the support platform 6, and the side of the support platform 6 facing away from the platform is used to support the plate.

[0063] In this embodiment, by setting up a support platform 6, it is possible to support the plate between the platform and the plate, and to raise the plate. In combination with the previous embodiments, it can be understood that when the two ends of the clamping assembly 1 are respectively connected to the connecting member 4 and the connecting element 5, and the clamping module 2 is located on the connecting member 4, the connecting member 4 and the connecting element 5 will raise the distance between the clamping assembly and the plate due to their own thickness. By setting up a support platform 6 to support the plate, it is possible to achieve a lifting effect. In addition, the setting of the support platform 6 can also avoid contact between the plate and the platform, and achieve a separation effect, which is convenient for repairing and replacing the support platform 6.

[0064] In addition, the through holes on the platform and the adsorption holes on the support platform 6 can be holes with relatively small pore diameters and can be multiple in number, for example, arranged in a matrix shape.

[0065] The utility model also relates to a processing device, combined with Figure 1-5 As shown, it includes a platform, a processing mechanism and the fixing mechanism 100 in the previous embodiment. The processing mechanism is used to process the plate fixed on the platform by the fixing mechanism 100.

[0066] By adopting the fixing mechanism 100 in the above embodiment, the plate can be fixed while preventing the edge of the plate from warping, thereby facilitating processing.

[0067] In one embodiment of a processing device, Figure 1-5 As shown, there are multiple fixing mechanisms 100, and each fixing mechanism 100 is sequentially arranged along the arrangement direction of the plates so as to be able to fix the plates one by one.

[0068] In this embodiment, by providing a plurality of fixing mechanisms 100 , a plurality of plates can be clamped and fixed, thereby facilitating simultaneous processing and improving processing efficiency.

[0069] In combination with the previous embodiment, preferably, the fixing mechanism 100 may also include multiple connecting frames 7, and one connecting frame 7 is used to connect and fix at least two support platforms 6. If the arrangement of the multiple fixing mechanisms 100 is linearly arranged along the X direction, the connecting frames 7 connect the two support platforms 6 between every two support platforms 6. If the arrangement of the fixing mechanisms 100 is in a matrix arrangement, the connecting frames 7 can be set between every two support platforms 6 to connect the two support platforms 6, or can be set between four support platforms 6 to connect the four support platforms 6.

[0070] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.

[0071] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
