[0002] At present, in the production process of enterprises, the inspection of materials or products is achieved manually. Since the quality of materials or products needs to be inspected manually, there is a disadvantage of low efficiency in material or product inspection. In order to improve the efficiency of inspection, many optical inspection devices have appeared in the market, most of which use photoelectric switch lateral inspection and lever-type mechanical inspection. The photoelectric switch lateral inspection is affected by the running vibration of the conveyor belt, resulting in unstable inspection. The lever-type mechanical inspection occupies too much height space and is not suitable for use with telescopic fitting templates. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in combination with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0029] In order to solve the problems existing in the prior art, the utility model proposes a precision material detection device, which includes a frame 1 with a hollow; a tooth plate 2, which is a fan-shaped structure, and the root is rotatably mounted on the frame 1, the front part of the tooth plate 2 is a tooth structure edge with a curved and continuously arranged tooth structure, and the root of the tooth plate 2 has a lever 2 extending in the opposite direction to the front; a detection wheel 5 is rotatably mounted below the tooth plate 2 through a detection wheel pin 6, and the outer ring surface of part of the detection wheel 5 protrudes from the edge of the tooth plate; a gear shaft 7 is rotatably mounted on the tooth plate 2, and the gear shaft 7 has a tooth structure on the outer sleeve, and the tooth structure is engaged with the tooth structure edge of the tooth plate 2; a fan-shaped baffle 8 is fixedly mounted on the gear shaft 7 and can rotate with the gear shaft 7; a reflective photoelectric switch 12 is mounted on the frame 1 and the transmitting end corresponds to the hollow; the tooth plate 2 can drive the fan-shaped baffle 8 to rotate through the gear shaft 7, so that the fan-shaped baffle 8 blocks the hollow or dismantles the hollow.

[0030] like Figure 1-3 As shown, the root of the toothed plate 2 is mounted on the frame 1 through the rotating shaft 4, the spring 9 is mounted on the frame 1 through bolts, the switch bracket 10 is fixedly mounted on the frame 1, the reflective photoelectric switch 12 is mounted on the frame 1 and the transmitting end corresponds to the hollow part, the limit screw 11 is mounted on the frame 1, and its threaded part is connected to the lever 3, the gear shaft 7 is fixedly mounted on the frame 1, and the adjusting screw 13 can adjust the position and installation angle of the detection device.

[0031] like Figure 4 As shown, the limit screw 11 is placed vertically with the lever 3, and its threaded part is connected with the lever 3. The head of the screw contacts the surface of the frame 1 to accurately position the lever 3. Specifically, the head of the limit screw 11 is flush with the bottom surface of the frame, and the threaded part plays the role of anchoring and reinforcement, which enhances the positioning performance of the limit screw 11. In addition, the limit screw 11 can also withstand greater pressure and vibration, thereby preventing the movement of the lever 3 caused by the working process, and further ensuring the movement accuracy. When the threaded end of the limit screw 11 is shorter, the farther the lever 3 and the tooth plate 2 are from the material position, the material thickness increases before it can touch the detection wheel 5; when the threaded end of the limit screw 11 is longer, the closer the lever 3 and the tooth plate 2 are from the material position, the material thickness decreases before it can touch the detection wheel 5; the position of the double-stage lever can be adjusted according to the material thickness to achieve more efficient material detection.

[0032] like Figure 5As shown, the tooth plate 2 is a fan-shaped structure with a radius of 80mm. A toothed structure is provided on the arc. The toothed structure meshes better with the outer tooth structure of the gear shaft 7 to ensure transmission accuracy. The root of the tooth plate 2 is installed on the frame 1 through the rotating shaft 4 to ensure that when the material passes through the detection wheel 5, the tooth plate 2 rotates around the rotating shaft 4. The root of the tooth plate 2 has a lever 2 extending in the opposite direction to the front, and the spring 9 is connected to the lever. When the material passes, the tooth plate 2 returns to its initial position under the combined force of its own gravity and the contraction of the tension spring 9.

[0033] like Figure 6 As shown, the reflective photoelectric switch 12 is mounted on the switch bracket 10. The working principle of the reflective photoelectric switch 12 is mainly based on the reflection of infrared or visible light. The reflective photoelectric switch 12 is composed of a transmitter and a receiver. The transmitter emits light. When an object approaches, the light is reflected by the object and then received by the receiver. The receiver converts the received optical signal into an electrical signal, thereby realizing the detection of the object. In addition, the reflective photoelectric switch 12 usually has a hysteresis characteristic. Even if the detected object shakes within a small range, it will not affect the output state of the switch, so that it can remain in a stable working area.

[0034] like Figure 7 As shown, the fan-shaped baffle 8 has a semicircular structure and is installed on the gear shaft 7. It rotates with the rotation of the gear shaft 7. With the increase of material, the detection wheel 5 drives the tooth plate 2 to rotate around the rotating shaft 4. The rotation of the tooth plate 2 drives the gear shaft 7 to rotate, and the fan-shaped baffle 8 installed on the gear shaft 7 also rotates accordingly. At this time, the fan-shaped baffle 8 is working. With the engagement of the tooth structure of the tooth plate 2 with the tooth structure of the outer sleeve of the gear shaft 7, the rotation angle of the fan-shaped baffle 8 increases. The maximum rotation angle of the fan-shaped baffle 8 is 170°. The rotation of the fan-shaped baffle 8 will block the signal light of the reflective photoelectric switch 12. At this time, the signal is disconnected, and the material detection can be completed through the position where the signal is disconnected.

[0035] The working principle of a precision material detection device is as follows: the detection device is arranged above the conveyor belt, and the conveyor belt drives the material to touch the detection wheel 5. As the thickness of the material changes, the detection wheel 5 drives the tooth plate 2 to rotate around the rotating shaft 4. As the tooth structure of the tooth plate 2 meshes with the tooth structure of the outer sleeve of the gear shaft 7, the gear shaft 7 is driven to rotate under the rotation of the tooth plate 2, and the fan-shaped baffle 8 installed at the other end of the gear shaft 7 also rotates synchronously, so that the light of the reflective photoelectric switch 12 that can originally connect the signal is blocked, the signal is disconnected, and the material can be detected. After the material passes, the detection wheel 7 returns to its initial position under the combined force of the gravity of the tooth plate 2 and the contraction of the tension spring 9.

[0036] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
