Description

Technical Field

[0001] This utility model relates to the field of sensor bracket technology, and in particular to a triangulation distance sensor bracket for product flatness detection. Background Technology

[0002] Triangulation distance sensors are based on the trigonometric theorems of geometric optics, measuring distance through the interaction of a laser beam with the surface of the object being measured. The sensor emits a laser beam, which is directed at a specific angle (direct or oblique incidence) onto the surface of the object. The laser light is reflected and scattered on the surface, and the reflected light is focused by a lens onto a photoelectric position sensor (such as a CCD, CMOS, or PSD), forming a light spot. When the object moves along the laser direction, the position of the light spot on the sensor shifts proportionally to the distance the object moves. An algorithm (such as the proportional relationship of similar triangles) converts this light spot displacement into the distance between the object and the sensor baseline. A triangulation distance sensor is a collective term for multiple components, which must be stably mounted together using a mounting bracket.

[0003] Throughout the triangulation process, due to the large number of components involved and the need to ensure stable installation, the structure of the support is usually quite complex, which in turn makes the processing and assembly of the support quite complicated and difficult to meet the usage requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a triangulation distance sensor bracket for product flatness detection in order to solve the problem of complex bracket structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A first fixing component and a second fixing component for fixing the infrared emitter and the CCD detector are respectively provided on one side of the mounting frame. An aperture is provided directly below the CCD detector. A third fixing component for fixing the aperture is provided on one side of the mounting frame. A light shield is provided below the infrared emitter and the CCD detector. A fourth fixing component for fixing the light shield is provided on one side of the mounting frame. The light shield is located between the CCD detector and the aperture.

[0007] As a further description of the above technical solution: the first fixing component includes a detachable fixing plate mounted on a fixing frame, and the infrared emitter is mounted on the fixing plate by screws, wherein the end face of the fixing plate that contacts the infrared emitter completely covers the side of the infrared emitter.

[0008] As a further description of the above technical solution: the second fixing component includes a clamping plate and a stabilizing block fixedly mounted on the fixing frame. The CCD detector passes through the clamping plate and is fixed to the stabilizing block by screws. The front end of the clamping plate can be adjusted for clamping tightness by bolts.

[0009] As a further description of the above technical solution: the axes corresponding to the centers of the clamping plate and the stabilizing block are in a vertical state.

[0010] As a further description of the above technical solution: the third fixing component includes a connecting frame fixedly installed on the fixing frame, and the aperture is fixedly installed on the lower end face of the connecting frame, wherein the connecting frame has a circular hole in the middle that is adapted to the aperture.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: This example provides a triangulation sensor bracket for product flatness detection. See [link / reference]. Figure 1 - Figure 3 Specifically, it includes a mounting bracket 1, with an infrared emitter 11 and a CCD detector 12 on one side of the mounting bracket 1. A first fixing component and a second fixing component for fixing the infrared emitter 11 and the CCD detector 12 are respectively provided on one side of the mounting bracket 1. An aperture 13 is provided directly below the CCD detector 12. A third fixing component for fixing the aperture 13 is provided on one side of the mounting bracket 1. A light shield 14 is provided below the infrared emitter 11 and the CCD detector 12. A fourth fixing component for fixing the light shield 14 is provided on one side of the mounting bracket 1. The light shield 14 is located between the CCD detector 12 and the aperture 13.

[0023] The first, second, third, and fourth fixing components can fix all the components required for detection. The structure is very simple, but all the components are concentrated on the fixing frame 1. The distribution of the components is reasonable and does not affect the path of the laser. The device is highly practical and meets the usage requirements.

[0024] The first fixing component includes a fixing plate 2 that is detachably mounted on a fixing frame 1. The infrared emitter 11 is mounted on the fixing plate 2 by screws, wherein the end face of the fixing plate 2 that contacts the infrared emitter 11 completely covers the side of the infrared emitter 11.

[0025] Since the side of the infrared transmitter 11 is completely covered by the side of the fixing plate 2, the installation area of ​​the infrared transmitter 11 is large enough to ensure the stability of the infrared transmitter 11 during use and to stably emit laser.

[0026] The second fixing component includes a clamping plate 3 and a stabilizing block 31 fixedly installed on the fixing frame 1. The CCD detector 12 passes through the clamping plate 3 and is fixed to the stabilizing block 31 by screws. The front end of the clamping plate 3 can be adjusted by bolts to adjust the clamping tightness. The axis corresponding to the center of the clamping plate 3 and the stabilizing block 31 is vertical.

[0027] First, pass the CCD detector 12 through the clamping plate 3. Then, fix the upper end of the CCD detector 12 to the stabilizing block 31 with screws. Finally, tighten the clamping plate 3 to firmly fix the CCD detector 12. Since the axis corresponding to the center of the clamping plate 3 and the stabilizing block 31 is vertical, the CCD detector 12 is in a vertical state, which ensures that the laser can be received very accurately and accurate measurement can be performed.

[0028] The third fixing component includes a connecting frame 4 fixedly installed on the fixing frame 1, and an aperture 13 fixedly installed on the lower end face of the connecting frame 4. The connecting frame 4 has a round hole in the middle that is adapted to the aperture 13.

[0029] The circular hole on the connector 4 is adapted to the middle of the aperture 13, so that the lower end of the connector 4 will not affect the laser reflection being received by the CCD detector 12. Even if the integration of the bracket is high, the laser path will not be compressed.

[0030] The fourth fixing component includes a positioning frame 5 fixedly installed on one side of the fixing frame 1, and a light shield 14 fixedly installed on the lower end face of the positioning frame 5;

[0031] The positioning frame 5 is installed between the infrared emitter 11 and the CCD detector 12, so that the light shield 14 can take into account both the incident and reflected laser light. The positioning frame 5 is located between the first fixed component and the second fixed component, saving space.

[0032] The mounting bracket 1 consists of four detachable aluminum alloy plates;

[0033] Aluminum alloy plates have high rigidity, which can significantly reduce the impact of vibration on measurement accuracy. It should be noted that this bracket must be used in pairs. The detection element on each bracket only detects the height of one side of the workpiece. The height difference between the two sides is compared to see if it exceeds the error, and then the levelness is judged.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
