DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0026] Combination Figure 1-Figure 7 The utility model is a detection fixture with a marking and positioning function, comprising a detection table 1, the detection table 1 is placed on one side of an endless conveyor belt 2, a baffle 101 is fixed on one side of the detection table 1 and is located above the endless conveyor belt 2, the endless conveyor belt 2 is located on the opposite side of the baffle 101 and is provided with a push-out mechanism 3, a detection component 4 is connected to the bottom of the top plate of the detection table 1, the push-out mechanism 3 comprises a fixed frame 301 fixed on one side of the endless conveyor belt 2, the fixed frame 301 is located on the conveying side and is provided with an electric push rod 302, a push plate 303 is fixed at one end of the electric push rod 302, and a reflector 304 is fixed above the push plate 303.

[0027] Specifically, when in use, start the circular conveyor belt 2 to transport the parts to the baffle 101 and stop transmission, start the electric push rod 302 on the fixed frame 301 to push the push plate 303 forward, and cooperate with the baffle 101 to clamp the parts. After clamping, the electric push rod 302 automatically stops pushing. At this time, the detection component 4 directly above the baffle 101 moves to the position where the reflector 304 is sensed and then stops moving. The moving distance is the length of the part. This component is easy to use and does not require other operations on the parts. The length detection is completed during the clamping process. The detection is stable and the results are accurate, which reduces damage to the parts, reduces the operating steps, and improves the detection efficiency.

[0028] The utility model is further described below in conjunction with embodiments.

[0029] Embodiment 1:

[0030] Combination Figure 3-Figure 7, the detection component 4 includes an electric screw 405 installed inside the detection platform 1, a moving block 402 is threadedly connected to the electric screw 405, a detection module 401 is connected to the bottom of the moving block 402, a camera 403 is connected to the middle position of the bottom of the detection module 401, and a displacement sensor 6 is fixed on the top of the detection platform 1 above the moving block 402. When the clamping is completed, the electric screw 405 is started to rotate, and the moving block 402 threadedly connected to the electric screw 405 moves in the opening of the detection platform 1, and the detection module 401 at the bottom moves accordingly. When the bottom camera 403 senses the light signal emitted by the reflector 304, the device stops moving, and the displacement sensor 6 analyzes the moving distance of the moving block 402 and lights up to display the detection result. The component has high positioning accuracy, simplifies the detection steps, and has a simple structure and is easy to maintain. The above-mentioned displacement sensor 6 is designed as a non-contact displacement sensor, and its specific working principle is the existing technology, which will not be repeated here, and the model used is not limited.

[0031] The circular conveyor 2 is located at one side of the output end of the detection table and is fixed with a push-out mechanism 3. The circular conveyor 2 is fixed with a guide plate 201 on the opposite side of the push-out mechanism 3 at the output end. The guide plate 201 is designed as an inclined surface. Bars 2011 are fixed on both sides of the guide plate 201. A collection box 5 is placed between the two bars 2011. The circular conveyor 2 is located opposite to the detection table 1 and is provided with the same push-out mechanism 3 and collection box 5. The tops of the push plates 303 of the two push-out mechanisms 3 are not provided with reflective plates 304. When the displacement sensor 6 analyzes and detects unqualified, the electric push rod 302 at the detection table 1 moves backward to release the parts, and the circular conveyor 2 starts to drive the parts to be transported to the push-out mechanism 3 at the output end and stops. The electric push rod 302 here pushes the push plate 303 to push the parts out of the conveyor belt and drop them into the corresponding collection box 5. When the inspection is qualified, the parts are released and the annular conveyor belt 2 will drive the parts to be transported to the push-out mechanism 3 opposite the inspection table 1 and stop. The electric push rod 302 here pushes the push plate 303 to push the parts out of the conveyor belt and drop them into the corresponding collection box 5 for collection. In this way, qualified and unqualified parts are distinguished and collected, realizing automated operation and reducing labor costs. The guide plate 201 is designed as an inclined surface to facilitate material dropping, increase buffering, and prevent parts damage. The fixed bars 2011 on both sides of the guide plate 201 can quickly locate the position of the collection box 5 to prevent position deviation and affect part collection.

[0032] Embodiment 2:

[0033] Combination Figure 2-Figure 7 The contact surfaces of the baffle plate 101 and the push plate 303 with the parts are fixed with rubber pads 1011. Fixing the rubber pads 1011 on the contact surfaces of the baffle plate 101 and the push plate 303 with the parts can effectively prevent damage to the parts during clamping, and can enhance the clamping effect and improve the operational stability during clamping.

[0034] Two positioning protrusions 202 are fixed on the side of the circular conveyor 2 close to the detection platform 1, and two positioning holes 102 are opened on one side of the detection platform 1. The positioning protrusions 202 are inserted into the positioning holes 102 for positioning. Two positioning protrusions 202 are set on the side of the circular conveyor 2 close to the detection platform 1, and inserted into the corresponding positioning holes 102 of the detection platform 1. The placement position of the detection platform 1 can be quickly positioned, thereby improving the accuracy of device detection.

[0035] A fill light 404 is arranged at the bottom of the detection module 401 parallel to the camera 403. The fill light 404 is arranged parallel to the camera 403 to adapt to different light environments, and can well capture the light of the reflector 304 to improve the detection environment.

[0036] A rubber block 4021 is fixed on both sides of the moving block 402 . Fixing the rubber blocks 4021 on both sides of the moving block 402 can effectively prevent damage to components caused by collision, and increasing the buffer can improve the detection accuracy of the bottom detection module 401 and the camera 403 .

[0037] Reflector 304 is made of aluminum-based reflector. Aluminum-based reflector uses high-purity aluminum plate as the base material, and the surface is specially treated to form a hard, wear-resistant and weather-resistant reflective layer. Aluminum-based reflector has high reflectivity and low light scattering characteristics, which can greatly improve the detection accuracy and detection light environment.
