[0040] The working principle of the part error proofing detection device is as follows:
[0041] The riveting head 800 is placed on the part placing seat 510, specifically, the ball head 810 is placed in the placing groove 511, and the two hole positions of the first branch frame 820 correspond to the first error proofing protrusion 521 and the second error proofing protrusion 531, and at the same time, the error proofing stop lever 540 abuts against the edge of the first branch frame 820, as shown. Figure 6 As shown. Since the rivet head has the specifications of Φ7 ball head and Φ8 ball head, wherein the end face diameter of the Φ7 ball head is 18.2mm, and the end face diameter of the Φ8 ball head is 19.2mm. When the telescopic assembly 200 is in action, the movable piece 400 can amplify the size deviation of the ball head 810 of different specifications through the lever principle, and whether the triggering end of the movable piece 400 triggers the first sensing piece 300 when the contact end of the movable piece 400 contacts with the ball head 810 serves as the distinction of the specifications of the ball head 810; specifically, when the ball head 810 is the Φ8 ball head, the movable piece 400 moves to the position as shown in Figure 4 , and the triggering end is within the sensing range of the first sensing piece 300; when the ball head 810 is the Φ7 ball head, the movable piece 400 moves to the position as shown in Figure 5 , and the triggering end is not within the sensing range of the first sensing piece 300; whether the first sensing piece 300 senses or not can distinguish the ball head 810 of different specifications.
[0042] Embodiment Two
[0043] This embodiment is a second embodiment of a part mistake-proof detection device, which is similar to the first embodiment, and the difference lies in that, as shown in Figures 1 to 6 , the first sensing piece 300 and the telescopic assembly 200 are located on one side of the first support seat 520, and the part placing seat 510 is located on the other side of the first support seat 520. The telescopic assembly 200 is a horizontal telescopic assembly, which includes a gas cylinder 210 and a second mounting seat 220, the cylinder seat of the gas cylinder 210 is connected with the base 100 through the second mounting seat 220, and the piston rod of the gas cylinder 210 is slidingly connected with the movable piece 400.
[0044] Among them, the movable piece 400 includes a movable rod, the triggering end includes a first protrusion 410 connected to the first end of the movable rod, and the first protrusion 410 is arranged close to the first sensing piece 300; the contact end includes a second protrusion 420 connected to the second end of the movable rod, and the second protrusion 420 is arranged close to the slot of the placing groove 511.

It should be noted that, since the first support seat 520 is arranged as an L-shaped structure, it can form an empty space relative to the movable rod to avoid hindering the movement of the movable rod. When the gas cylinder 210 drives the movable rod to move, the first protrusion 410 has an overlapping area with the sensing range of the first sensing piece 300, and the first protrusion 410 can pass above the sensing end of the first sensing piece 300, thereby triggering the first sensing piece 300 to sense.
[0045] As shown inFigure 2 and Figure 3 As shown, the placement surface of the part placement seat 510 is provided with a notch structure 513 that communicates with its edge. The notch structure 513 is used to mate with the second protrusion 420. The notch structure 513 prevents the rivet head 800 from obstructing the contact between the second protrusion 420 and the ball head 810 when it is placed on the part placement seat 510. Figure 7 As shown.
[0046] The working principle of a part error prevention detection device in this embodiment is as follows:
[0047] The rivet head 800 is placed at the part placement seat 510. When the cylinder 210 is activated, the movable rod can amplify the dimensional deviation of ball heads 810 of different specifications through the lever principle. When the second protrusion 420 extends from the notch structure 513 and contacts the ball head 810, whether the first protrusion 410 triggers the first sensor 300 to distinguish the specifications of the ball head 810 is used.
