Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] Example:
[0033] refer to Figures 1-3A detection device for detecting the position of pins on a product includes: a positioning plate 1 for supporting the position of the product 5; a detection mechanism 2 for detecting the position of pins on the product 5 is arranged on the side of the positioning plate 1; the detection mechanism 2 includes a mounting block 21 and a positioning rod 22; the positioning rod 22 is slidably engaged with the mounting block 21; one end of the positioning rod 22 abuts against one end of the pin on the product 5; and an identification part 221 extends from the end of the positioning rod 22 away from the pin. A 3D camera 3 is arranged on the side of the identification part 221, facing the identification part 221 and identifying the position of the identification part 221. When the position of the pin on the product 5 is within the normal range, the position of the identification part 221 when the positioning rod 22 abuts against the end face of the pin is also within the normal range. At this time, the 3D camera 3 takes pictures of the identification parts 221 of multiple positioning rods 22, identifies them, and analyzes the images through a processor to determine that the position of the pin is within the specified range. When the pin position on product 5 is abnormal and outside the normal range, the position of the identification part 221 when the positioning rod 22 abuts against the end face of the pin is also outside the normal range. At this time, the 3D camera 3 takes pictures of the identification parts 221 of multiple positioning rods 22, analyzes them through the processor, and finds out that there are pins in incorrect positions. It then alarms and notifies the staff, so as to complete the detection of pins on product 5 in a timely and quick manner.
[0034] refer to Figure 3 To ensure that the positioning rod 22 fully contacts and abuts against the end face of the pin, thereby ensuring the accuracy of the position of the identification unit 221 and avoiding errors, a tension spring 23 is provided on the mounting block 21. One end of the tension spring 23 is connected to the mounting block 21, and the other end is connected to the positioning rod 22, providing a force for the positioning rod 22 to move towards the pin. Specifically, a pull rod 24 is inserted into the positioning rod 22, and a through hole 25 is provided on the mounting block 21 to allow one end of the tension spring 23 to pass through. Thus, one end of the tension spring 23 passes through the through hole 25 and hangs on the pull rod 24, while the other end of the tension spring 23 is connected to the end of the positioning rod 22 away from the pin. Thus, the tension spring 23 provides a force for the positioning rod 22 to move towards the end face of the pin, avoiding false alarms caused by errors in the position of the identification unit 221 due to the positioning rod 22 not moving to the correct position.
[0035] refer to Figure 3To prevent defective products from being released due to monitoring failure of the 3D camera 3, a reference block 26 is provided on the mounting block 21. A reference part 261 is provided at the end of the reference block 26 facing the 3D camera 3. The reference part 261 is positioned facing the 3D camera 3, so that the 3D camera 3 can monitor the reference part 261 in real time. Whether the 3D camera 3 can identify the reference part 261 in real time can determine whether the 3D camera 3 is malfunctioning. Specifically, the reference part 261 has a first notch, so that the end face of the reference part 261 facing the 3D camera 3 forms a first low part 2611 and a first high part 2612. There is a height difference between the first low part 2611 and the first high part 2612, so whether the 3D camera 3 can identify the height difference of the reference part 261 can determine whether the 3D camera 3 is malfunctioning.
[0036] refer to Figure 3 The recognition part 221 has a second notch, so that the end face of the recognition part 221 facing the 3D camera 3 forms a second low part 2211 and a second high part 2212. There is a height difference between the second low part 2211 and the second high part 2212, which facilitates the 3D camera 3 to identify the recognition part 221.
[0037] refer to Figure 1 and Figure 2 To detect the actual situation of the pin as needed, two detection mechanisms 2 are arranged, one on each side of the end face of the pin, so as to determine the position of the pin ends respectively.
[0038] refer to Figure 1 and Figure 2 To ensure the accuracy of the product 5's position on the positioning tray 1, a limit plate 11 and a positioning post are bolted to the positioning tray 1. The limit plate 11 is bolted to the four corners of the positioning tray 1 to limit the product 5 at the four corners of the positioning tray 1, thereby limiting the overall position of the product 5 on the positioning tray 1. The positioning post cooperates with the hole on the product 5 to accurately position the product 5 on the positioning tray 1, thus ensuring the accuracy of the product 5's position on the positioning tray 1.
[0039] refer to Figure 1 and Figure 2A support frame 4 is installed below the positioning tray 1, and the positioning tray 1 and the support frame 4 are slidably fitted together. A first driving component 41 is bolted to the support frame 4 to drive the positioning tray 1 to move horizontally on the support frame 4, so that one end of the pin of the product 5 on the positioning tray 1 abuts against the positioning rod 22 of the detection mechanism 2. A second driving component 42 is bolted to the support frame 4, and the second driving component 42 is connected to a guide rod 43. The guide rod 43 is connected to another detection mechanism 2, so that the positioning rod 22 of the detection mechanism 2 moves up and down in the height direction, so that one end of the positioning rod 22 abuts against the other end of the pin. Thus, the 3D camera 3 identifies the position of the recognition part 221 of the positioning rod 22 and analyzes whether it is within the normal range, thereby determining whether the positions of both ends of the pin are within the normal range. Both the first driving component 41 and the second driving component 42 can be cylinders.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
