[0034] The following is a further detailed description of the embodiments shown in the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, the automatic rivet pulling machine of the present invention comprises: a track assembly 1, a pushing device 2, a lock buckle supply device 3, a glue dispensing device 4, and a rivet locking device 5. The track assembly 1 is used to support and limit the left and right positions of the profile 7 and is mounted on a bracket 6 in the front-to-back direction. The pushing device 2 is also mounted on the bracket 6 in the front-to-back direction and positioned adjacent to the track assembly 1, driving the profile 7 along the track assembly 1. The lock buckle supply device 3 is used to deliver lock buckles 8 to the profile 7 in the processing position. The glue dispensing device 4 is used to apply waterproof glue to the rivet position of the lock buckle 8 after the rivet is pulled. The rivet locking device 5 is used to rivet the profile 7 to the lock buckle 8. In this embodiment, the lock buckle supply device 3 and the rivet locking device 5 are respectively mounted on the left and right sides of the track assembly 1 in the processing position. The glue dispensing device 4 is mounted on the side of the track assembly 1 further downstream than the rivet locking device 5. Each of the above devices can be connected to a control system for automated control.

[0036] The profile 7 can be made of aluminum, stainless steel, iron, zinc or other materials. Figure 6 and Figure 7 As shown, in this embodiment, the profile 7 is made of aluminum and is provided with two groups of holes, each of which is provided with two mounting holes 71. It is necessary to rivet the two lock buckles 8 at the two groups of holes with a rivet gun. The profile 7 is provided with vertically extending side panels 72 on the left and right sides of its bottom plate. Correspondingly, as shown in FIG. Figure 8 As shown, two front and rear rivet holes 81 are also opened at corresponding positions on the lock buckle 8.

[0037] like Figure 3As shown, the track assembly 1 includes: a carrier frame 11 extending in the front-to-back direction, two rows of limiting wheels 12 installed on both sides of the carrier frame 11, a locking and positioning mechanism 13, and a locking mechanism 14. The carrier frame 11 is used to support the profile 7 and is supported by the bottom plate of the profile 7. The two rows of limiting wheels 12 are blocked outside the left and right side plates 72 of the profile 7 to limit the left and right positions of the profile 7 when it moves.

[0038] The lock positioning mechanism 13 is installed on one side of the carrier 11 and is used to limit the lock 8 when it is not fixed. Figure 4 As shown, the lock positioning mechanism 13 includes a stopper 131 and a first cylinder 132 for driving the stopper 131 upward or downward. The stopper 131 is provided with a lock placement position 133. When the profile 7 is transported to the processing position for the lock, the first cylinder 132 drives the stopper 131 downward, and the lock 8 is then placed at the lock placement position 133 on the stopper 131. At this time, the two rivet holes 81 on the lock 8 exactly correspond to the two mounting holes 71 on the profile 7.

[0039] like Figure 5 As shown, the locking mechanism 14 includes an eighth cylinder 141 and a pressure block 142. The pressure block 142 is arranged on one side of the carrier 11. The eighth cylinder 141 drives the pressure block 142 to move left or right to lock or release the profile 7 at the processing position.

[0040] like Figure 9 As shown, the pusher device 2 includes: a first motor 21, a sliding assembly 22 driven by the first motor 21 to move back and forth, a first base plate 23 synchronously connected to the sliding assembly 22, and a pusher and gripper device 24 mounted on the first base plate 23. In this way, when the sliding assembly 22 moves back and forth driven by the first motor 21, the first base plate 23 and the pusher and gripper device 24 also move back and forth synchronously.

[0041] like Figure 10 As shown, the pusher and gripper device 24 includes: a second base plate 241, a second slide rail 242, a second cylinder 243, a third base plate 244, a third cylinder 245, and a gripper 246. The second slide rail 242 is vertically slidably mounted on the second base plate 241, the second cylinder 243 is mounted on the second base plate 241 and connected to the second slide rail 242, the third base plate 244 is fixedly connected to the second slide rail 242, and the third cylinder 245 is mounted on the third base plate 244. The third cylinder 245 drives the gripper 246 to perform a clamping or releasing action.

[0042] When a profile 7 is placed on the track assembly 1, the second cylinder 243 drives the second slide rail 242 to descend and drives the third base plate 244 and the third cylinder 245 and the clamp 246 fixed to the third base plate 244 to move downward. After the clamp 246 drops into place, the first motor 21 is activated and drives the sliding assembly 22 to move forward. At the same time, the material pushing and clamping device 24 moves forward. When the clamp 246 reaches the corresponding position of the profile 7, the first motor 21 stops, and the third cylinder 245 is activated to drive the clamp 246 to clamp the edge of the profile 7. Then the first motor 21 starts again, and the clamp 246 drives the profile 7 forward to the processing position.

[0043] like Figure 11 As shown, the lock supply device 3 includes: a vibration plate 31, a lock conveying device 32, a lock picking device 33 and a lock limiting mechanism 34. The vibration plate 31 has a disc-shaped vibrating container for holding and vibrating the lock 8. The lock conveying device 32 is used to receive the lock 8 output from the vibration plate 31 and transport the lock 8 to a set position in the direction of the track assembly 1. The lock limiting mechanism 34 is used to limit the lock 8 transported to the set position. The lock picking device 33 is used to pick up the lock 8 transported to the set position by the lock conveying device 32 and transport it to the lock placement position 133 of the lock positioning mechanism 13.

[0044] like Figure 12 As shown, the lock conveying device 32 includes: a lock limiting plate 321 equipped with a guide groove 322, a vibrating feeder 323 acting on the lock limiting plate 321, and a lock supporting workpiece 324 located at the output end of the lock limiting plate 321. The lock 8 is output from the vibrating plate 31 to the guide groove 322. When the vibrating feeder 323 is activated, it vibrates the lock 8 on the guide groove 322 into the lock supporting workpiece 324, i.e., the set position mentioned above. The edge of the lock supporting workpiece 324 is provided with a vertical rib to limit the lock 8.

[0045] The lock limit mechanism 34 is mainly arranged below the lock supporting workpiece 324. Figure 13As shown, the latch retaining mechanism 34 includes a sensor 341 located on one side of the latch support workpiece 324, two latch retaining push rods 342 located below the latch support workpiece 324, and a fifth cylinder 343 for raising and lowering the two latch retaining push rods 342. The latch support workpiece 324 is provided with two through-holes 3241, which correspond to the positions of the two latch retaining push rods 342 and the two rivet holes 81 of the latch 8. When the sensor 341 senses the presence of the latch 8 on the latch support workpiece 324, the fifth cylinder 343 is activated to raise the latch retaining push rods 342. The top ends of the latch retaining push rods 342 pass through the through-holes 3241 and are inserted into the rivet holes 81 of the latch 8, thereby retaining the latch 8 on the latch support workpiece 324 and awaiting removal.

[0046] The locking device 33 is arranged above the locking conveying device 32. Figure 14 As shown, the latch mechanism 33 includes a second motor 331, a fourth cylinder 332, a fourth base plate 333, a first slide rail 334, a vacuum generator 335, and a suction cup 336 connected thereto. The fourth cylinder 332 is slidably mounted on the first slide rail 334. The second motor 331 is connected to the fourth cylinder 332, thereby driving the fourth cylinder 332 to slide back and forth along the first slide rail 334. The fourth cylinder 332 is connected to the suction cup 336, thereby driving the suction cup 336 to rise and fall.

[0047] like Figure 15 As shown, the rivet locking device 5 includes a fourth motor 51, a third motor 52, a fifth base plate 53, a sixth base plate 54, and a rivet gun 55. The rivet gun 55 is mounted on the sixth base plate 54. The third motor 52 is mounted on the fifth base plate 53. The third motor 52 is connected to the sixth base plate 54 and drives the sixth base plate 54 and the rivet gun 55 to move vertically. The fourth motor 51 is connected to the fifth base plate 53 and drives the fifth base plate 53, the third motor 52, the sixth base plate 54, and the rivet gun 55 mounted thereon to move horizontally forward and backward. The rivet gun 55 is positioned above the profile 7 at the processing position.

[0048] like Figure 16 and 17As shown, the glue dispensing device 4 includes a sixth cylinder 41, a slide rail assembly 42, a glue dispensing gun 43, and a seventh cylinder 44. The sixth cylinder 41 is connected to the glue dispensing gun 43 and can move it up and down. The slide rail assembly 42 is slidable forward and backward, and the sixth cylinder 41 is mounted on the slide rail assembly 42. The seventh cylinder 44 is connected to the sixth cylinder 41 and can move the sixth cylinder 41 forward and backward along the guide rail of the slide rail assembly 42. The rivets at the two rivet holes 81 on the lock buckle 8 require application of waterproof glue. The sixth cylinder 41 and the seventh cylinder 44 can drive the glue dispensing gun 43 to move forward and backward and up and down, thereby applying waterproof glue to the connection between the lock buckle 8 and the rivet, i.e., the two rivet holes 81.

[0049] The operation process of the automatic nail pulling machine of the present invention is as follows:

[0050] 1. The profile 7 to be installed with the lock is placed on the carrier 11 of the track assembly 1 and is restricted from left and right movement by the limiting wheels 12;

[0051] 2. The second cylinder 243 in the pusher device 2 descends, driving the third base plate 244 and the gripper 246 fixed to the third base plate 244 downward. After the gripper 246 has descended into position, the first motor 21 is activated, driving the sliding assembly 22 forward, and simultaneously the pusher gripper device 24 moves forward. When the gripper 246 reaches the corresponding position of the profile 7, the first motor 21 stops, and the third cylinder 245 is activated, driving the gripper 246 to clamp the edge of the profile 7. The first motor 21 is then activated again, and the gripper 246 drives the profile 7 forward to the processing position.

[0052] 3. After the profile 7 reaches the processing position, the eighth cylinder 141 in the locking mechanism 14 drives the pressing block 142 to lock the side of the profile 7, securing the profile 7. Simultaneously, the first cylinder 132 in the locking and positioning mechanism 13 descends, driving the retaining workpiece 131 downward until it contacts the surface of the profile 7.

[0053] 4. After the profile 7 is secured in the processing position, the vibration plate 31 is activated, vibrating the lock 8 into the guide groove 322 and restrained by the lock limit plate 321. The vibration feeder 323 is then activated, vibrating the lock 8 onto the lock support workpiece 324. The lock 8 is detected by the sensor 341 on the lock support workpiece 324, and the fifth cylinder 343 is activated to raise the lock limit push rod 342. The top end of the lock limit push rod 342 is inserted into the two rivet holes 81 of the lock 8, restraining the lock 8 on the lock support workpiece 324.

[0054] 5. Next, the fourth cylinder 332 in the locking mechanism 33 drives the suction cup 336 downward, while the vacuum generator 335 is activated. The suction cup 336 descends into position and engages the locking buckle 8. The fourth cylinder 332 then activates and ascends, driving the suction cup 336 and the locking buckle attached to it upward.

[0055] 6. After the fourth cylinder 332 rises to its proper position, the second motor 331 is activated, driving the fourth base plate 333 forward, thereby moving the suction cup 336 and the associated workpiece forward.

[0056] 7. The suction cup 336, holding the lock buckle, moves to a position directly above the limiting workpiece 131 and stops. Then, the fourth cylinder 332 starts to descend, and the suction cup 336, holding the lock buckle, descends simultaneously. After descending to the desired position, the vacuum generator 335 stops, and the lock buckle is placed into the lock buckle placement position 133 of the limiting workpiece 131.

[0057] 8. After the latch is placed in the processing position, the fourth cylinder 332 drives the suction cup 336 and the corresponding workpiece to rise. After the fourth cylinder 332 is raised into position, the second motor 331 is activated to drive the fourth cylinder 332, the suction cup 336, and the corresponding workpiece back to the initial position above the latch conveyor 32 to wait;

[0058] 9. The fourth motor 51 in the rivet locking device 5 is activated, driving the rivet gun 55 and the corresponding workpiece to the processing position directly above the lock buckle. Then, the third motor 52 is activated, and the rivet gun 55 moves downward. After the rivet gun 55 reaches the first rivet, it locks the rivet, riveting one end of the lock buckle to the profile 7.

[0059] 10. After the first hole is riveted, the third motor 52 is activated, driving the rivet gun 55 to rise to a set height. Then, the fourth motor 51 is activated, driving the rivet gun 55 to move to another hole where a rivet is to be riveted, and then it stops. The third motor 52 is then activated, driving the rivet gun 55 downward. The rivet gun 55 descends to the second rivet, locking the rivet and riveting the other end of the buckle to the profile 7. After the rivets in the above positions are riveted, the rivet gun 55 returns to its initial position.

[0060] 11. Next, the first cylinder 132 raises the limiting workpiece 131, while the eighth cylinder 141 simultaneously drives the pressing block 142 to extend, thereby releasing the locked profile 7;

[0061] 12. After the profile 7 is released, the first motor 21 starts and drives the sliding assembly 22 forward. Simultaneously, the material pushing and gripping device 24, which is connected to the sliding assembly 22 and the first base plate 23, moves forward. When the gripping device 246 reaches the corresponding position of the profile 7, the first motor 21 stops, and the third cylinder 245 actuates to drive the gripping device 246 to clamp the edge of the profile 7. The first motor 21 then starts again, and the gripping device 246 drives the profile 7 forward to the dispensing position.

[0062] 13. After the profile 7 reaches the dispensing position, the sixth cylinder 41 descends, driving the dispensing gun 43 to descend to the corresponding rivet. The gun tip of the dispensing gun 43 now just contacts the surface of the rivet, and the dispensing gun 43 starts dispensing.

[0063] 14. After dispensing glue at the first rivet, the sixth cylinder 41 rises, driving the glue gun 43 to the set position. Then, the seventh cylinder 44 is activated, pushing the glue gun 43 to the top of the next location where glue is to be dispensed, guided by the slide assembly 42. The sixth cylinder 41 then descends, driving the glue gun 43 to the corresponding rivet. The tip of the glue gun 43 now contacts the surface of the rivet, and the glue gun 43 starts dispensing glue again.

[0064] 15. After the dispensing work at the above positions is completed, the dispensing gun 43 returns to the initial position and waits for the next dispensing work;

[0065] 16. After the dispensing gun 43 returns to its initial position, the first motor 21 activates and drives the sliding assembly 22 forward, while simultaneously moving the material pushing and gripping device 24 forward. When the gripping device 246 reaches the corresponding position of the profile 7, the first motor 21 stops, and the third cylinder 245 activates and drives the gripping device 246 to clamp the edge of the profile 7. The first motor 21 then starts again, and the gripping device 246 drives the profile 7 forward to the discharge position.

[0066] 17. After all the above is completed, the automatic nail pulling machine completes the operation and the profile 7 can be taken away.

[0067] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
