Specifically, the first placement piece 200 is sleeved on the first placement piece 200. The first placement piece 200 and the second placement piece 300 are fixed to the base 100 by means of a latch. Different types of first placement pieces 200 and second placement pieces 300, i.e., first grooves 210 and second grooves 310 of different sizes can be replaced to adapt to the assembly of torsion springs 600 of different sizes. It should be noted that, of course, the two can also be integrally arranged in some embodiments. Further, the base 100 is fixed on a turntable (not shown) and rotates with the turntable to process various parts of each hinge.

[0048] Further, the upper ends of the first placement piece 200 and the second placement piece 300 extend from the upper end of the base 100, the upper end of the first placement piece 200 is provided with a first groove 210 for placing the horizontally arranged torsion spring 600, the upper end of the second placement piece 300 is provided with a second groove 310 for placing the buckle 800, and the upper end of the base 100 is formed with a third groove 110 for placing the tail buckle 900.

The protruding portion 120 is located on the side of the tail buckle 900 facing away from the buckle plate 800, and the protruding portion 120 and the second storage piece 300 form a third groove 110. Furthermore, when the tail buckle 900 is placed in the third groove 110, it is engaged with the buckle plate 800, and the connecting holes on the tail buckle 900 and the buckle plate 800 are coaxial with the torsion spring 600. It should be noted that the torsion spring 600 and the buckle plate 800 are placed in corresponding positions by corresponding manipulators, and the tail buckle 900 is engaged with the buckle plate 800 by corresponding manipulators.

[0049] Furthermore, the torsion spring 600 has a first arm 610 and a second arm 620 arranged at its two ends.

It should be understood that a notch 211 is provided on the side wall corresponding to the first groove 210 and the first arm 610. When the torsion spring 600 is placed in the first groove 210, the first arm 610 abuts against the notch 211, thereby limiting the initial state of the torsion spring 600 and ensuring the accuracy of assembly.

[0050] It should be noted that holes are provided on the inner wall of the first groove 210 and the side wall of the second storage piece 300 facing the buckle plate 800, and an adsorption member 220 for adsorbing the torsion spring 600 is provided at the hole. Specifically, the adsorption member 220 is preferably a magnet to prevent the torsion spring 600 and the buckle plate 800 from shifting, thereby improving the stability of the torsion spring 600 and the buckle plate 800 and improving the efficiency of assembly.

[0051] Furthermore, a hanging portion 910 corresponding to the second arm 620 is provided on the tail buckle 900, and the positioning mechanism 400 can drive the first arm 610 to move upward to drive the torsion spring 600 to rotate, so that the second arm 620 hangs on the hanging portion 910, so that the first arm 610 is twisted to the first position.

[0052] Furthermore, the arm body 700 can be placed on the upper end of the base 100, and the arm body 700 corresponds to the first arm 610. When the arm body 700 is subjected to external force, it can move horizontally in the direction of the torsion spring 600 to the first position, so that the connecting hole on it is coaxial with the connecting hole on the tail buckle 900, so that the first arm 610 and the end of the arm body 700 close to it are abutted. It should be noted that a bayonet corresponding to the first arm 610 is provided at the end of the arm body 700 facing the torsion spring 600 (not shown in the figure), and when the arm body 700 moves to the first position, the first arm 610 is abutted against the bayonet.

[0053] Furthermore, the nail is passed through the arm body 700, the tail buckle 900, the connecting holes on the buckle plate 800 and the hollow position of the torsion spring 600 by means of a needle threading device, so that the four are assembled together. It should be noted that the needle threading device and the above-mentioned manipulator are both existing technologies and will not be described in detail here.

[0054] That is, the assembly device can make the torsion spring 600 coaxial with the connecting holes on the arm body 700, the buckle plate 800 and the tail buckle 900, and can make the second arm 620 hang on the hanging part 910 through the positioning mechanism 400, so that the first arm 610 is twisted to the first position and connected to the arm body 700, so as to facilitate subsequent nailing operations, have a high degree of automation and precision, and can greatly improve assembly efficiency and save production costs.

[0055] In one embodiment, the pushing mechanism 500 includes a first driving component 510, a second driving component 520 and a pushing arm 530. The pushing arm 530 corresponds to the end of the arm body 700 away from the torsion spring 600. The output end of the first driving component 510 is connected to the pushing arm 530 and can drive the pushing arm 530 to move up and down. The output end of the second driving component 520 is connected to the first driving component 510, and the second driving component 520 can drive the first driving component 510 to drive the pushing arm 530 to move horizontally in the direction of the torsion spring 600 to the first position, that is, when the corresponding manipulator places the arm body 700 on the upper end of the base 100, the first driving component 510 will drive the pushing arm 530 to move downward to the end of the arm body 700 away from the torsion spring 600, and further, the second driving component 520 will drive the first driving component 510 to drive the pushing arm 530 to push the arm body 700 to move in the direction of the torsion spring 600 to the first position, so that the first arm 610 is in contact with the end of the arm body 700 close to the first arm 610, and the connecting hole on the arm body 700 is concentric with the connecting hole on the tail buckle 900.

[0056] Specifically, the first driving assembly 510 includes a first mounting seat 511 and a vertically arranged first cylinder 512, the first cylinder 512 is fixed on the first mounting seat 511, the pushing arm includes a guide portion 531, an extension portion 532 and a pressing portion 533, the first mounting seat 511 is provided with a first through hole 5111 adapted to the guide portion 531, the guide portion 531 passes through the first through hole 5111 and is connected to the output end of the first cylinder 512, the extension portion 532 is arranged at the lower end of the guide portion 531 and extends downward, the pressing portion 533 is arranged on the side of the guide portion 531 facing the torsion spring 600 and extends in the direction of the torsion spring 600, the pressing portion 533 corresponds to the upper end of the arm body 700, and the extension portion 532 corresponds to the end of the arm body 700 away from the torsion spring 600.

[0057] The second driving assembly 520 includes a second mounting seat 521 and a second cylinder 522. The second mounting seat 521 is provided with a guide block 5211 arranged in a horizontal direction. The first mounting seat 511 is provided with a second through hole 5112 matching the guide block 5211. The second cylinder 522 is laterally fixed on the second mounting seat 521, and its cylinder rod is connected to the first mounting seat 511.

[0058] During operation, the first cylinder 512 drives the pushing arm 530 to move downward so that the extension part 532 corresponds to the end of the arm body 700 away from the torsion spring 600. Further, the second cylinder 522 drives the first mounting seat 511 so that the extension part 532 pushes the arm body 700 to the first position. Further, the first cylinder 512 drives the pushing arm 530 to move downward again so that the pressing part 533 is pressed on the upper end of the arm body 700, thereby limiting the arm body 700 to ensure accuracy and stability during stapling.

[0059] Furthermore, a movable hole 121 is provided on the side of the protruding portion 120 facing the tail buckle 900, and a pressure spring 122 and a pressure plate 123 are provided in the movable hole 121. The pressure plate 123 is subjected to force by the pressure spring 122 and abuts against the tail buckle 900, that is, the tail buckle 900 and the buckle piece 800 are pressed against the placement object through the pressure plate 123 to prevent the tail buckle 900 and the buckle piece 800 from falling off, thereby ensuring the accuracy and stability of subsequent nailing. Specifically, the movable hole 121 passes through the protruding portion 120, and a fixing block 124 corresponding to the movable hole 121 is provided on the side of the protruding portion 120 away from the tail buckle 900.

The fixing block 124 facilitates the disassembly and assembly of the pressure spring 122 and the pressure plate 123, and facilitates subsequent maintenance and replacement.

[0060] In one embodiment, the positioning mechanism 400 includes a pressing arm 410 and a pushing arm 420. The base 100 is provided with a movable opening 130 that passes through the upper and lower ends thereof and corresponds to the arm body 700. The pressing arm 410 is arranged at the movable opening 130. A limiting portion 411 corresponding to the torsion spring 600 is arranged on the side of the pressing arm 410 facing the placement object. The pressing arm 410 can move horizontally and linearly in the direction of the torsion spring 600 so that the limiting portion 411 and the first groove 210 form a space, and the torsion spring 600 can rotate in the space.

[0061] Furthermore, the pushing arm 420 is arranged on a side corresponding to the pressing arm 410 and the first arm 610, and is inclined upward. The pushing arm 420 can move upward along its inclined direction to push the torsion spring 600 to rotate and the first arm 610 to twist. Specifically, the second arm 620 is abutted against the side wall corresponding to the first groove 210 and the second arm 620, so that the second arm 620 is hung on the hanging portion 910. Further, the first arm 610 is twisted to an installation position connected to the arm body 700 of the hinge, that is, through the cooperation of the pressing arm 410 and the pushing arm 420, the first arm 610 and the second arm 620 can be rotated to corresponding installation positions for positioning, so as to facilitate the assembly of the torsion spring 600, which can avoid the occurrence of excessive force on the first arm 610 and damage, and can greatly improve the service life. The overall design is reasonable, the structure is simple and stable, and can improve assembly efficiency and reduce costs.

[0062] In one embodiment, the positioning mechanism 400 also includes a lifting plate 430, which is adapted to the movable port 130 to ensure the stability of the up and down movement of the lifting plate 430, and is connected to the pushing arm 420 and the pressing arm 410. The lifting plate 430 can move up and down, and its movement has a second position, a third position and a fourth position arranged in sequence from bottom to top.

[0063] When the lifting plate 430 moves from the second position to the third position, it can drive the pressing arm 410 and the pushing arm 420 to move horizontally in the direction of the torsion spring 600 to reduce the stroke of the pushing arm 420 .

[0064] When the lifting plate 430 moves from the third position to the fourth position, it can drive the pushing arm 420 to move upward along its inclined direction to push the torsion spring 600, so that the second arm 620 is hung on the hanging part 910, and the first arm 610 is further twisted, and the structure is compact and stable.

[0065] In one embodiment, the positioning mechanism 400 further includes a trigger member 440, which is disposed below the base 100. A rolling member 431 is disposed at the lower end of the lifting plate 430, and an upwardly inclined slope 441 is disposed at the upper end of the trigger member 440. The rolling member 431 can climb from the lower end of the slope 441 to the upper end of the slope 441 to drive the lifting plate 430 to move upward from the second position to the third position and the fourth position. That is, the rolling member 431 is squeezed by the slope 441 to drive the lifting plate 430 to move upward. The structure is simple and the design is ingenious. It can reduce costs, facilitate maintenance and replacement, save energy, and adapt to use in different environments. It can accurately control the strength of the push arm 420 to avoid damaging the first arm 610 on the torsion spring 600 due to excessive or insufficient force. Specifically, the rolling member 431 is preferably a bearing, and the rolling member 431 can improve the smoothness of the work and increase the service life.

[0066] In one embodiment, the positioning mechanism 400 also includes a reset spring 450, and both ends of the reset spring 450 are in contact with the base 100 and the lifting plate 430. Specifically, a step (not shown) is provided at the lower end of the lifting plate 430, and corresponding grooves are provided at the upper end of the step and the lower end of the base 100. The upper and lower ends of the reset spring 450 extend into the corresponding grooves respectively. When the rolling element 431 is disconnected from the ramp 441, the reset spring 450 can drive the lifting plate 430 to move from the fourth position via the third position to the second position, that is, reset the lifting plate 430, so as to facilitate the operation of subsequent processes. It has the advantages of simple and reliable structure, low cost, energy saving and environmental protection.

[0067] In one embodiment, an opening 432 is provided at the upper end of the lifting plate 430, and the pressing arm 410 is arranged at the opening 432. The opening 432 forms two connecting walls 433 at the upper end of the lifting plate 430, and the connecting wall 433 is provided with a first guide hole 434 and a second guide hole 435 inclined in a direction away from the torsion spring 600, wherein the first guide hole 434 and the second guide hole 435 have the same inclination angle, two first guide holes 434 are arranged at intervals along the movement direction of the pressing arm 410, and the second guide hole 435 is located above the first guide hole 434.

[0068] Further, the movable opening 130 is provided with a third guide hole 131 on the inner wall corresponding to the first guide hole 434. The third guide hole 131 is arranged along the movement direction of the pressing arm 410, that is, it is arranged horizontally. The pressing arm 410 is provided with a first connecting member 412 corresponding to the first guide hole 434, that is, there are two first connecting members 412, and the two first connecting members 412 can support the pressing arm 410 to prevent it from rotating. Further, the two ends of the first connecting member 412 respectively pass through the corresponding first guide hole 434 and extend into the corresponding third guide hole 131. The function of the guide hole 131 is to guide the first connecting member 412 so that it moves linearly along the horizontal plane. When the lifting plate 430 moves from the second position to the third position, the first guide hole 434 will squeeze the first connecting member 412 and push the first connecting member 412 to move in the direction of the torsion spring 600. It should be noted that the distance between the two first connecting members 412 is smaller than the length of the third guide hole 131. When the lifting plate 430 moves to the third position, the end of the third guide hole 131 close to the torsion spring 600 abuts against the first connecting member 412 close to the torsion spring 600 to limit the position and improve stability.

[0069] Furthermore, a guide groove 421 is provided on the side of the pressing arm 410 facing the pushing arm 420, and the guide groove 421 has the same inclination direction as the pushing arm 420. The pushing arm 420 is arranged in the guide groove 421 to ensure the stability of the pushing arm 420 and save space. Furthermore, a first avoidance hole 422 arranged along its inclination direction is provided on the inner bottom wall of the guide groove 421, and a second connecting member 423 with one end passing through the first avoidance hole 422 is provided on the pushing arm 420. The first avoidance hole 422 plays a role in avoiding and limiting the second connection. Further, the two ends of the second connecting member 423 respectively extend into the corresponding second guide holes 435. When the first guide hole 434 squeezes the first connecting member 412, the second guide hole 435 synchronously squeezes the second connecting member 423, so that the second connecting member 423 synchronously moves in the direction of the torsion spring 600. It has the advantages of simple and stable structure, convenient production and processing, and low production cost.

[0070] It should be noted that the first connecting member 412 and the second connecting member 423 are preferably cylindrical pins, and the first guide hole 434 and the second guide hole 435 are adapted to the first connecting member 412 and the second connecting member 423 .

[0071] Furthermore, a vertically arranged second avoidance hole 436 is provided at the lower end of the first guide hole 434, and the lower end of the first guide hole 434 is connected to the upper end of the second avoidance hole 436; a fourth guide hole 437 is horizontally provided at the lower end of the second guide hole 435, and the second guide hole 435 is connected to an end of the fourth guide hole 437 away from the torsion spring 600. The function of the second avoidance hole 436 is to limit and avoid the first connecting member 412 when the lifting plate 430 moves from the third position to the fourth position, so that when the pressing arm 410 limits the torsion spring 600, the lifting plate 430 can still move upward, and further drive the second connecting member 423 through the fourth guide hole 437, and drive the pushing arm 420 to move upward in an inclined direction, so as to push the first arm 610 to twist to the installation position.

[0072] In one embodiment, the side of the pressing arm 410 facing the torsion spring 600 is provided with an inclined surface 413 inclined in a direction away from the torsion spring 600, and the limiting portion 411 is provided on the inclined surface 413 and close to the upper end of the inclined surface 413. The limiting portion 411 is an arc-shaped notch adapted to the outer wall of the torsion spring 600. It should be noted that the height of the side wall of the first groove 210 close to the limiting portion 411 is lower than the side wall away from the limiting portion 411, so that the limiting portion 411 and the torsion spring 600 can be easily adjusted. The torsion spring 600 is connected, and the side wall of the first groove 210 close to the limiting portion 411 is provided with a chamfer 212 which can fit with the inclined surface 413 for limiting. Furthermore, when the chamfer 212 fits with the inclined surface 413, a notch 211 is formed between the side wall of the first groove 210 away from the limiting portion 411 and the upper end of the inclined surface 413, and the second arm 620 extends from the notch 211. The width of the notch 211 is smaller than the diameter of the torsion spring 600 to prevent the torsion spring 600 from falling off.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
