[0025] Example

[0026] See also Figure 1-6 The utility model provides a technical solution: an anti-mistake device for multiple rivet delivery during riveting operation, comprising a mounting frame 1, two limiting frames 2 are arranged on one side of the bottom of the mounting frame 1, a feeding pipe 5 is arranged on one side of the limiting frame 2, a riveting punch 8 is arranged on one side of the top of the mounting frame 1, the feeding pipe 5 is connected to the feeding mechanism of the external rivet body 7, the riveting punch 8 is connected to the power source, a rivet body 7 is arranged inside the limiting frame 2, a plate 4 for riveting the rivet body 7 is arranged on the lower side of the mounting frame 1, the power source pushes the riveting punch 8 to move downward, and one side of the two limiting frames 2 is respectively connected to the pulling mechanism, so that after the rivet body 7 is riveted with the plate 4 under the action of the riveting punch 8, the rivet body 7 is riveted with the plate 4 together, a photoelectric switch 6 for monitoring and preventing multiple rivet bodies 7 is installed on one side of the mounting frame 1, the riveting punch 8 is located at the top of the rivet body 7, and the rivet body 7 is located at the top of the plate 4.

[0027] In order to facilitate the feeding of the rivet body 7, an insertion groove 101 is opened in the middle of the mounting frame 1, and a detection groove 102 and a first conveying groove 104 are respectively provided on the inner wall of the insertion groove 101. A second conveying groove 501 is provided inside the conveying pipe 5, and the second conveying groove 501 is connected with the first conveying groove 104. The first conveying groove 104 and the second conveying groove 501 are used for feeding the rivet body 7. A second limiting groove 201 is opened on one side of the limiting frame 2, and the second limiting groove 201 is respectively connected with the insertion groove 101 and the first conveying groove 104. During the riveting operation, the rivet body 7 is conveyed to the inside of the first conveying groove 104 through the second conveying groove 501, and then the rivet body 7 enters the inner side of the second limiting groove 201.

[0028] In order to facilitate the detection of the number of rivet bodies 7 and prevent an excessive number of rivet bodies 7, first limiting grooves 105 are provided on both sides of the mounting frame 1, one side of the two limiting frames 2 is installed on the inner side of the first limiting groove 105, the inner wall of the detection groove 102 is provided with a mounting groove 103 located on one side of the mounting frame 1, and the photoelectric switch 6 is fixed to the inner side wall of the mounting groove 103. When the rivet body 7 is conveyed in the first conveying groove 104 and the second conveying groove 501, the rivet body 7 enters the inner side of the second limiting groove 201. When the number exceeds one, the rivet body 7 will be located on one side of the detection groove 102. At this time, the photoelectric switch 6 detects that the number of rivet bodies 7 inside the second limit groove 201 is greater than one, and an alarm electrically connected to the photoelectric switch 6 in the outside world generates sound and light prompts. A second through hole 107 is opened on one side of the top of the mounting frame 1. The second through hole 107 is connected to the clamping frame 3 through bolts, and the outer side of the feed pipe 5 is inserted into the inner side of the clamping frame 3, and the photoelectric switch 6 is connected to the controller of the punching machine. The model of the photoelectric switch 6 is M6.

[0029] Working principle or structural principle: when the sheet 4 needs to be riveted with the rivet body 7, the feed pipe 5 is connected to the feeding mechanism of the external rivet body 7, the riveting punch 8 is connected to the power source, the power source pushes the riveting punch 8 to move downward, and one side of the two limit frames 2 is respectively connected to the pulling mechanism, so that after the rivet body 7 is riveted with the sheet 4 under the action of the riveting punch 8, the limit frame 2 leaks the rivet body 7 under the action of the pulling mechanism;

[0030] During the riveting operation, the rivet body 7 is conveyed to the inside of the first conveying groove 104 through the second conveying groove 501, and then the rivet body 7 enters the inside of the second limiting groove 201. At this time, the bottom of the rivet body 7 is exposed from the bottom side of the limiting frame 2. At this time, the riveting punch 8 moves downward, so that the riveting punch 8 abuts against the top of the rivet body 7, so that the rivet body 7 and the plate 4 are riveted together;

[0031] When the rivet body 7 is conveyed in the first conveying groove 104 and the second conveying groove 501, the rivet body 7 enters the inner side of the second limiting groove 201. When the number of rivet bodies 7 conveyed exceeds one, the rivet body 7 will be located on one side of the detection groove 102. At this time, the photoelectric switch 6 detects that the number of rivet bodies 7 inside the second limiting groove 201 is greater than one, so that the alarm electrically connected to the photoelectric switch 6 in the outside world produces sound and light prompts. At the same time, when the photoelectric switch 6 detects that the number of rivet bodies 7 inside the second limiting groove 201 is greater than one, the riveting punch 8 is controlled to stop moving downward to prevent the riveting punch 8 from being damaged. The number of rivet bodies 7 is detected by the photoelectric switch 6, so that the rivet body 7 performs a fool-proof operation before the riveting process to avoid damage to the riveting punch 8.

[0032] In summary, the photoelectric switch 6 can quickly and accurately detect the number of rivet bodies 7 in the second limit groove 201. Once it is found that the number exceeds one, the alarm will be triggered immediately and the riveting punch 8 will be controlled to stop moving, avoiding production interruptions and delays caused by the wrong number of rivet bodies 7. The fool-proof operation can ensure that the correct number of rivet bodies 7 is used in each riveting process, avoiding product quality problems caused by insufficient or excessive number of rivet bodies 7, and improving the overall quality of the product. When the number of rivet bodies 7 is abnormal, the sound and light prompts of the alarm can quickly attract the attention of the operator, so that corresponding measures can be taken in time, reducing the safety risks caused by equipment failure or misoperation.
