Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] like Figures 1-4 As shown, Figure 1 Schematic diagram of the three-dimensional structure of the position detection mechanism; Figure 2 A schematic diagram of the three-dimensional structure of the detection carrier 2; Figure 3 is a schematic diagram of the three-dimensional structure of the movable block 31; Figure 4 It is a schematic diagram of the coordination of the movable rod 32, the first detection block 33 and the second detection block 34. The position detection mechanism includes a detection driver 1, a detection carrier 2, a detection member 3 and a sensing member 4. The detection carrier 2 is arranged at the output end of the detection driver 1, the detection member 3 is arranged on the detection carrier 2, and the sensing member 4 is arranged on the detection carrier 2, and the sensing end of the sensing member 4 faces the detection member 3. When in use, the detection driver 1 drives the detection carrier 2 to move, and the detection carrier 2 drives the detection member 3 and the sensing member 4 to move together. When the detection member 3 contacts the component, the detection member 3 is detected by the sensing member 4 to determine whether the current component is placed as required. Specifically, the detection driver 1 is a cylinder.

[0028] The detection carrier 2 includes a first carrier plate 21, a second carrier plate 22, and a bracket 23. The first carrier plate 21 is connected to the output end of the detection driver 1, the second carrier plate 22 is connected to the first carrier plate 21, the bracket 23 is disposed on the second carrier plate 22, the detection member 3 is slidably connected to the second carrier plate 22, and the sensing member 4 is disposed on the second carrier plate 22. Furthermore, the detection carrier 2 also includes a guide rod 24, which is disposed on the bracket 23, and the detection member 3 is slidably mounted on the guide rod 24. In this embodiment, there are two guide rods 24, which are spaced apart and disposed on the bracket 23, and the detection member 3 is slidably mounted on the two guide rods 24.

[0029] The detection member 3 includes a movable block 31, a movable rod 32, a first detection block 33, and a second detection block 34. The movable block 31 is slidably arranged on the second supporting plate 22, and the movable block 31 is slidably sleeved on the two guide rods 24. The movable rod 32 is arranged on the movable block 31, and the movable rod 32 passes through the bracket 23. The movable rod 32 can move relative to the bracket 23. The first detection block 33 and the second detection block 34 are both sleeved on the movable rod 32. The first detection block 33 and the second detection block 34 are both located on the upper part of the bracket 23. There is a gap 35 between the first detection block 33 and the second detection block 34, and the sensing end of the sensing member 4 faces the gap 35. Furthermore, a matching groove 311 is opened at the end of the movable block 31 away from the movable rod 32, and the matching groove 311 corresponds to the shape of the component.

[0030] The sensing element 4 includes a support plate 41 and a sensor 42. The support plate 41 is mounted on the second carrier plate 22. The sensor 42 is located at one end of the support plate 41 away from the second carrier plate 22. The sensing end of the sensor 42 faces the gap 35 between the first detection block 33 and the second detection block 34. In practical applications, there are two support plates 41 and two sensors 42. The two support plates 41 are positioned opposite each other on either side of the second carrier plate 22, and the two sensors 42 are mounted on each support plate 41. Specifically, the sensor 42 is a conventional infrared sensor that detects whether infrared light is blocked.

[0031] In another embodiment, the number of detection parts 3 and sensing parts 4 can be multiple. For example, when multiple parts need to be inspected, multiple workstations can be set up accordingly, and each workstation has a detection part 3 and a sensing part 4 for coordinated inspection. The structures of the detection part 3 and the sensing part 4 are basically the same, and perhaps adaptive shape changes can be made according to the shapes of different parts.

[0032] During operation, after a component is placed, the detection driver 1 drives the first carrier plate 21 to move toward the component. The first carrier plate 21 drives the second carrier plate 22, the bracket 23, and the other structures arranged on the two to move together. The matching groove 311 of the movable block 31 abuts against the component, and the movable block 31 will stop moving. At this time, the movable rod 32, the first detection block 33, and the second detection block 34 also stop moving. The second carrier plate 22, the support plate 41, and the sensor 42 will continue to move in the same direction under the continuous operation of the detection driver 1. After moving to the preset position, they will stop moving. The sensing end of the sensor 42 detects the gap 35 between the first detection block 33 and the second detection block 34. If the infrared light of the sensor 42 can pass through the gap 35, it proves that the installation position of the component meets the requirements. On the contrary, if the infrared light of the sensor 42 cannot correspond to the gap 35, that is, no infrared light passes within the gap 35, it means that the installation position of the component is too high or too low, and its installation position does not meet the requirements.

[0033] To sum up, after the parts are placed in the fixture, the detection driving part 1 drives the detection part 3 and the sensing part 4 to move through the detection carrier 2. After the detection part 3 contacts the parts, it moves relative to the detection carrier 2. After the detection carrier 2 stops moving, the sensing part 4 detects the current detection part 3 and uses this to determine whether the parts have been accurately placed. In this way, the detection accuracy of the parts can be greatly improved, avoiding affecting the subsequent assembly, and thus improving the overall production efficiency.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
