[0024] During assembly, the material to be assembled is inserted into the positioning groove 24 at the top of the positioning box 23 near the rear side of the assembly box 1, and then the rotating motor 21 is started to drive the turntable 22 to rotate, and the infrared transmitter 25 at the top of the positioning box 23 opposite to the positioning box 23 where the material is placed emits infrared rays, which are received by the infrared receiver 35 on the right side of the fixed bracket 31, thereby temporarily stopping the start of the rotating motor 21. During stamping, the rotating motor 21 drives the rotation of the turntable 22 to move the material with the rivet to the right side of the fixed bracket 31, and the infrared rays emitted by the infrared transmitter 25 and received by the infrared receiver 35 can be used to keep the material in the positioning groove 24 below the pressure head 34, and finally, the pressure head 34 can be moved downward by starting the hydraulic press 33 on the top of the stamping bracket 32, and the rivet can be stamped and assembled on the material in the positioning groove 24, and during stamping, the positioning groove 24 corresponding to the positioning groove 24 can be loaded again, and the rivet can be quickly assembled by analogy.

[0025] like Figure 4 As shown, the conveying mechanism 5 includes a conveyor belt 51, which is fixedly installed on the top of the L-shaped bracket 4 at a horizontal position, and a squaring box 52 is fixedly installed on the rear side of the top of the conveyor belt 51. A driving groove 53 is opened on the front side of the squaring box 52, and a driving motor 54 is fixedly installed on the left side of the squaring box 52. The output shaft of the driving motor 54 passes through the inner cavity of the driving groove 53 and is fixedly installed with a positive and negative threaded rod 55. The left and right sides of the positive and negative threaded rod 55 are both opened with threaded walls with opposite threads, and the outer walls of the two threaded walls are movably installed with clamping plates 56;

[0026] The rivet is placed vertically on the surface of the conveyor belt 51 and transported to the rear side. When it reaches the front side of the alignment box 52, the drive motor 54 is started to drive the forward and reverse threaded rods 55 in the drive groove 53 to rotate, so that the threaded clamps 56 on the left and right sides of the forward and reverse threaded rods 55 are brought close to each other to clamp the rivet, so that it is kept in the middle position of the top of the conveyor belt 51. Then, the output shaft of the drive motor 54 can be reversed to move the two clamps 56 to both sides and reset, so as to facilitate the subsequent clamping and feeding of the rivets.

[0027] like Figure 5 , Figure 6 As shown, the feeding mechanism 6 includes a driving bracket 61, which is fixedly installed on the left side of the vertical part of the L-shaped bracket 4, a driving plate 62 is fixedly installed on the left side of the top of the driving bracket 61, and a motor 63 is fixedly installed on the right side of the driving plate 62. A recessed groove is opened on the top of the driving plate 62, and the output shaft of the motor 63 penetrates into the recessed groove at the top of the driving plate 62 and is fixedly installed with a threaded rod 64. A moving plate 65 is threadedly installed on the outer wall of the threaded rod 64, and the bottom of the moving plate 65 overlaps with the outer wall of the recessed groove, a hanging plate 66 is fixedly installed on the front side of the moving plate 65, and an electric push rod 67 is fixedly installed on the lower front side of the hanging plate 66, and a clamping mechanism 68 is arranged at the bottom end of the electric push rod 67, and the clamping mechanism 68 includes a clamping box 681, and the clamping box 68 The top of 1 is fixedly connected with the bottom of the electric push rod 1 67, and the left and right sides of the clamping box 681 are fixedly installed with electric push rods 2 682. The electric push rods 1 67 and the electric push rods 2 682 are powered by wire external power supply without affecting the movement. The relative output ends of the two electric push rods 2 682 are penetrated into the inner cavity of the clamping box 681 and fixedly installed with hanging rods 683. The bottom of the clamping box 681 is provided with a slide groove 684 that penetrates into the inner cavity. The bottom ends of the two hanging rods 683 penetrate the slide groove 684 to the bottom of the clamping box 681 and are fixedly installed with a clamping hanging plate 685. The bottoms of the two clamping hanging plates 685 are fixedly installed with mirror-image rubber clamps 686. The rubber clamps 686 can increase the friction between the rivets and the metal material, making the clamping more stable.

[0028] By starting the motor 63 on the right side of the driving plate 62 at the top of the driving bracket 61, the threaded rod 64 can be driven to rotate, so that the moving plate 65 drives the hanging plate 66 to move to the right. When it moves to the rightmost side of the recessed groove, the clamping mechanism 68 at the bottom of the electric push rod 1 67 can be located just above the rivet after the rivet is aligned. Then, the electric push rod 1 67 is started to drive the clamping box 681 to move downward, and the two electric push rods 2 682 on the left and right sides of the clamping box 681 are simultaneously started to use the hanging rod 683 to slide in the slide groove 684, so that the rubber at the bottom of the two clamping hanging plates 685 can be clamped. The glue clamp block 686 clamps and fixes the rivet, and then the electric push rod 1 67 is used to raise the overall clamping mechanism 68, and then the output shaft of the motor 63 is reversed to enable the movable plate 65 to drive the hanging plate 66 that fixes the electric push rod 1 67 to move to the left. When the movable plate 65 moves to the leftmost side of the recessed groove, the clamping mechanism 68 that clamps the rivet can be located directly above the positioning groove 24, and then the electric push rod 1 67 is moved downward to place the rivet stably on the top of the assembly material, and the rivet can be dropped by retracting the two electric push rods 2 682 at the same time.

[0029] The following is a detailed description of the working principle of the automatic riveting machine.

[0030] like Figure 1-6As shown, during assembly, the material to be assembled is inserted into the positioning groove 24 at the top of the positioning box 23 near the rear side of the assembly box 1, and then the rotating motor 21 is started to drive the turntable 22 to rotate, and the infrared transmitter 25 at the top of the positioning box 23 opposite to the material positioning box 23 is used to emit infrared rays, which are received by the infrared receiver 35 on the right side of the fixed bracket 31, thereby temporarily stopping the start of the rotating motor 21, and then the rivet is placed vertically on the surface of the conveyor belt 51 and transmitted to the rear side. When it reaches the front side of the alignment box 52, the driving motor 54 is started to drive the positive and negative threaded rods 55 in the driving groove 53 to rotate, so that the positive and negative threaded rods 55 The clamping plates 56 on the left and right sides of the screw thread are brought close to each other to clamp the rivet, so that it is kept in the middle position of the top of the conveyor belt 51. Then, the output shaft of the driving motor 54 can be reversed to move the two clamping plates 56 to both sides to reset. Then, the motor 63 on the right side of the driving plate 62 on the top of the driving bracket 61 is started to drive the threaded rod 64 to rotate, so that the moving plate 65 drives the hanging plate 66 to move to the right. When it moves to the rightmost side of the concave groove, the clamping mechanism 68 at the bottom of the electric push rod 67 can be located just above the rivet after being aligned. Then, the electric push rod 67 is started to drive the clamping box 681 to move downward, and the clamping box 681 is started synchronously. The two electric push rods 682 on the left and right sides of 81 can utilize the sliding of the suspension rod 683 in the slide groove 684 to enable the rubber clamping blocks 686 at the bottom of the two clamping suspension plates 685 to clamp and fix the rivet, and then utilize the electric push rod 1 67 to raise the entire clamping mechanism 68, and then utilize the reverse rotation of the output shaft of the motor 63 to enable the movable plate 65 to drive the suspension plate 66 that fixes the electric push rod 1 67 to move to the left side. When the movable plate 65 moves to the leftmost side of the recessed groove, the clamping mechanism 68 that clamps the rivet can be located just above the positioning groove 24, and then the electric push rod 1 67 is moved downward to stably place the rivet on the top of the assembly material, and at the same time When the two electric push rods 2682 are retracted, the rivet can be dropped, and the rotating motor 21 drives the turntable 22 to rotate, so that the material with the rivet is moved to the right side of the fixed bracket 31, and the infrared rays emitted by the infrared transmitter 25 and received by the infrared receiver 35 can be used to keep the material in the positioning groove 24 below the pressure head 34, and finally, the pressure head 34 can be moved downward by starting the hydraulic press 33 on the top of the stamping bracket 32, and the rivet can be stamped and assembled on the material in the positioning groove 24, and during stamping, the positioning groove 24 corresponding to the positioning groove 24 can be loaded again, and the rivet can be quickly assembled by analogy.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
