Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Reference Figure 1-5The embodiment of the present invention provides an automatic fastening device for a 3D printer substrate, comprising a working platform 1, a piston frame 2 is arranged at the tail of the working platform 1, a cylinder 37 is arranged at the tail of the working platform 1, a traction component 22 is arranged inside the piston frame 2, a plurality of assembly components 3 are arranged at the head of the piston frame 2, and are used to assemble an assembly table 23, a quadrilateral enclosure 36 is displaceably connected in the working platform 1, the head of the quadrilateral enclosure 36 is fixedly connected to a substrate 35, and the tail of the quadrilateral enclosure 36 is covered in a movable The head of the plug frame 2 and the bottom of the base plate 35 are fixedly connected with multiple assembly tables 23. Each assembly component 3 includes a hollow column 4, a rotating plate 6, and two arc-shaped limiting plates 9. A rotating rod 8 is installed at the tail of the rotating plate 6. The rotating rod 8 rotates and extends into the inside of the piston frame 2. The rotating plate 6 is inside the hollow column 4. Two traction grooves 7 are installed in the mirror image at the tail of the rotating plate 6. The sides of the two arc-shaped limiting plates 9 are installed with displacement rods 21. The displacement rod 21 extends through the hollow column 4 to the hollow column 4. The tails of the two arc-shaped limiting pieces 9 are respectively displaced and assembled in the two traction grooves 7. The heads of the two arc-shaped limiting pieces 9 are provided with protruding hooks 20. The two protruding hooks 20 are used to lock the assembly platform 23. The traction assembly 22 is used to pull the rotating rods 8 on the multiple assembly components 3 to rotate together; by controlling the traction assembly 22, the multiple rotating rods 8 are rotated, and the rotating rods 8 pull the rotating piece 6 to rotate. During the rotation of the rotating piece 6, the traction groove 7 pulls the arc-shaped limiting piece 9 toward the two sides. The two arc-shaped limiting pieces 9 are displaced together, and then the tail of the assembly table 23 to be assembled is placed between the two arc-shaped limiting pieces 9 in the hollow column 4. After the assembly is completed, the traction component 22 is driven to operate, and the rotating piece 6 is rotated in different directions, thereby allowing the two traction grooves 7 to pull the two arc-shaped limiting pieces 9 to move inward, so that the arc-shaped limiting pieces 9 lock the assembly table 23 firmly. The purpose of removing the assembly table 23 is achieved by manipulating the traction component 22, and it is easy to assemble and remove the base plate 35.

[0025] The traction assembly 22 includes a plurality of rotating rings 25 with reserved tooth grooves, a displacement sheet 26 with reserved tooth grooves, and a spiral beryllium copper wire 29. The plurality of rotating rings 25 with reserved tooth grooves are each fixedly connected to the rotating rod 8. The rotating rings 25 with reserved tooth grooves are displaced and installed inside the piston frame 2. The displacement sheet 26 with reserved tooth grooves is always in a bite state with the plurality of rotating rings 25 with reserved tooth grooves. One side of the displacement sheet 26 with reserved tooth grooves extends through the piston frame 2 to the edge of the piston frame 2.

[0026] One end of the traction piece 27 is fixedly connected to the traction ring 31, and the traction ring 31 is used for the operator to pull the traction piece 27 and the displacement piece 26 with the reserved tooth socket; thereby, the traction piece 27 and the displacement piece 26 with the reserved tooth socket are easily manipulated.

[0027] A flexible silicone layer 32 is installed on the fitting area between the two arc-shaped limiting pieces 9 and the two protruding hooks 20 and the assembly platform 23 ; thereby increasing the resistance between the arc-shaped limiting pieces 9 and the assembly platform 23 , so that the arc-shaped limiting pieces 9 can be firmly locked 24 .

[0028] One end of the displacement rod 21 extending around the hollow column 4 is fixedly connected to the stop plate 33, and the end of the displacement rod 21 extending to the edge of the hollow column 4 is provided with a spiral beryllium copper wire 5 34, which is located between the stop plate 33 and the hollow column 4; thereby, the displacement rod 21 is always in a locked state due to the spiral beryllium copper wire 5 34.

[0029] No less than two displacement rods 21 are mounted on the arc-shaped limiting plate 9 , thereby making the displacement of the arc-shaped limiting plate 9 more stable.

[0030] The arc-shaped limiting piece 9 is displaced and installed in the traction groove 7, and a ball is rotatably installed at one end thereof; thereby reducing the resistance between the arc-shaped limiting piece 9 and the traction groove 7, so that the arc-shaped limiting piece 9 can be displaced smoothly.

[0031] Each arc-shaped limiting piece 9 is provided with a stop assembly, which includes an embedding hole 513 provided on the assembly table 23, and two displacement chambers 51 provided on the arc-shaped limiting piece 9. The two displacement chambers 51 are displacement-connected to the extrusion piece 52. One side of the extrusion piece 52 is fixedly connected to the displacement column 53, and the other side of the extrusion piece 52 is fixedly connected to the spiral beryllium copper wire 3 514. The end of the displacement column 53 away from the extrusion piece 52 is fixedly connected to the connecting column 54. The connecting column 54 is displacement-connected to the accommodating shell 56. One end of the connecting column 54 is embedded in the accommodating shell 56. The displacement chamber 2 57 is reserved in the accommodating shell 56. The connecting column 54 is inserted into one end of the accommodating shell 56. In the displacement chamber 2 57, the connecting column 54 is inserted into one end of the accommodating shell 56, and a spiral beryllium copper wire 1 55 is installed between the accommodating shell 56. The end of the accommodating shell 56 away from the displacement column 53 is installed with an arc-shaped locking piece 58. A connecting channel 59 is opened in the arc-shaped limiting piece 9. One end of the connecting channel 59 is connected with the two displacement chambers 1 51, and the other end of the connecting channel 59 is connected with the displacement chamber 3 510. The displacement chamber 3 510 is opened in the connecting channel 59. The displacement in the displacement chamber 3 510 is connected to the pressing platform 512. One end of the pressing platform 512 is connected to the spiral beryllium copper wire 2 511 installed in the displacement chamber 3 510. The other end of the pressing platform 512 is inserted into the embedding hole. 513; thus, during the displacement and locking of the arc-shaped limiting piece 9 to the assembly platform 23, the arc-shaped locking piece 58 is first fitted with the assembly platform 23, and then the arc-shaped limiting piece 9 is continuously displaced to pull the arc-shaped locking piece 58 and the accommodating shell 56 to move. Since the deformation force of the spiral beryllium copper wire 1 55 exceeds that of the spiral beryllium copper wire 3 514, the displacement column 53 and the extrusion piece 1 52 are first pushed to move. The displacement of the extrusion piece 1 52 causes the gas in the connection channel 59 to be compressed and displaced, and flows toward the displacement chamber 3 510, and then the compression platform 512 is pulled out of the displacement chamber 3 510 and poked into the embedding hole 513. Since the fitting surface of the compression platform 512 and the embedding hole 513 is inclined, the compression platform 5 12 fits smoothly with the embedding hole 513, and gradually applies a compressive impulse to allow the assembly table 23 to change in direction toward the rotating plate 6, and to be close to the rotating plate 6, so that the assembly of the assembly table 23 is more stable, and no gaps are generated in the upper and lower spaces, so as to avoid the substrate 35 from shaking up and down due to the gaps during production, causing production problems. In addition, during the continuous displacement of the arc-shaped limiting plate 9, the arc-shaped locking plate 58 is also continuously squeezed. After the compression platform 512 is close to the embedding hole 513, the gas in the connection channel 59 is compressed to the limit. When the extrusion plate 52 cannot be displaced, the spiral beryllium copper wire 55 begins to be compressed to provide space for the displacement of the arc-shaped locking plate 58 to ensure that the components will not be damaged.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
