Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and in particular to a measuring instrument with a lens and a laser sensor. Background Technology

[0002] An image measuring instrument is a high-precision optical measuring instrument based on CCD digital imaging technology. It achieves non-contact measurement through computer screen measurement and spatial geometric calculation. Its core components include a high-resolution CCD lens, a continuous zoom objective lens, a precision grating ruler, and dedicated measuring software, which can quickly capture images of objects and generate geometric dimension data.

[0003] The light source is a crucial component of a measuring instrument. Many commercially available measuring instruments have their light source and camera coaxial, which prevents the light source from affecting the measurement. However, this type of light source cannot be angled, making it inflexible. For example, CN202321003449.4, a high-precision measuring instrument, specifically discloses that "the CCD imaging device includes a CCD camera, a lens, and a light source; the lens is mounted on the lifting plate, the CCD camera is mounted on top of the lens; the light source is located below the CCD camera and mounted on the lens." While the light source and camera are coaxial, the light source cannot be angled, resulting in poor flexibility. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a measuring instrument with a lens and a laser sensor, whose light source can be oscillated, thus providing greater flexibility and overcoming the shortcomings of the existing technology.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] Please refer to Figures 1 to 7 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a measuring instrument having a lens and a laser sensor 45.

[0027] The combination of the detection camera 43 and the laser sensor 45 improves measurement accuracy, measurement range, and measurement efficiency. The light source 49 can be oscillated by the lamp holder 46, offering greater flexibility and applicability to more measurement environments.

[0028] This application provides a measuring instrument with a lens and a laser sensor 45, including a base 10; a mounting base 20 is disposed on the base 10; a y-axis sliding module 22 and a placement plate 23 are disposed on the mounting base 20; a workpiece is placed on the placement plate 23; a gantry 30 is slidably disposed on the y-axis sliding module 22; an x-axis sliding module 31 is disposed on the gantry 30; a z-axis sliding module 40 is disposed on the x-axis sliding module 31; a mounting frame 41 is disposed on the z-axis sliding module 40; a detection camera 43 and a laser sensor 45 are disposed on the mounting frame 41; a plurality of lamp holders 46 are disposed on the mounting frame 41; a light source 49 is disposed on the lamp holder 46, and the light source 49 can swing. The y-axis sliding module 22, x-axis sliding module 31, and z-axis sliding module 40 are ball screw servo modules. A first dust cover 24 is provided on the mounting base 20, covering the y-axis sliding module 22. A second dust cover 32 is provided on the gantry 30, covering the x-axis sliding module 31. The y-axis sliding module 22 drives the gantry 30 to move in the y-axis direction, the x-axis sliding module 31 drives the z-axis sliding module 40 to move in the x-axis direction, and the z-axis sliding module 40 drives the mounting bracket 41 to move up and down in the z-axis direction. This allows the detection camera 43, laser sensor 45, and light source 49 to move up and down, with excellent motion accuracy in the x, y, and z directions. During measurement, the workpiece is placed on the placement plate 23, the light source 49 illuminates the workpiece, and the detection camera 43 and laser sensor 45 measure the workpiece. The light source 49 can swing up and down on the lamp holder 46, so the illumination angle of the light source 49 can be changed, which can adapt to more measurement environments, and has good versatility and high flexibility. The first dust cover 24 and the second dust cover 32 have the function of dust protection to prevent dust from affecting accuracy.

[0029] Preferably, the base 10 has an adjustable first support 11 at its bottom; an adjustable second support 12 at its top; a support hole 21 at its bottom; a first inflatable pad 13 inside the support hole 21; and a portion of the second support 12 extending into the support hole 21, supporting the bottom surface of the base 10. The first support 11 and the second support 12 can be bolt-mounted for height adjustment, or hydraulically manufactured. The inflatable pad is made of elastic plastic / silicone / rubber and is filled with gas. The first inflatable pad 13 provides cushioning and shock absorption, ensuring measurement accuracy and reducing vibration errors.

[0030] Specifically, the base 10 is a hollow frame structure with six first supports 11 symmetrically arranged at the bottom and six second supports 12 symmetrically arranged at the top. The hollow frame structure reduces weight, and the two second supports 12 in the middle support the bottom surface of the base 10. The four second supports 12 extend into the support holes 21 and press against the first inflatable pad 13. This design facilitates height adjustment, improves force balance, reduces vibration, and makes adjustment more convenient.

[0031] Preferably, there are two mounting brackets 41, each equipped with a first clamping plate 42 and a second clamping plate 44. The first clamping plate 42 clamps the detection camera 43, and the second clamping plate 44 clamps the laser sensor 45. The two first clamping plates 42 are fastened together with screws, thus the assembly of the detection camera 43 and the laser sensor 45 is very convenient and efficient.

[0032] Preferably, the lamp holder 46 is provided with an arc-shaped hole 47 and a pivot hole 48; the end of the light source 49 is provided with a pivot and a limiting member, the pivot is inserted into the pivot hole 48, and the limiting member passes through the arc-shaped hole 47. The limiting member can be a screw or a pin. The pivot can be locked to the lamp holder 46 with a screw, and the screw can be loosened when adjustment is needed to allow the light source 49 to swing up and down. The arc-shaped hole 47 is a circular arc hole, and the curvature can be set as needed. There are several light sources 49, arranged in a frame or ring. In this embodiment, multiple light sources 49 are arranged in a polygonal shape, such as a rectangular frame, a hexagonal frame, an octagonal frame, etc., without specific limitations. Among them, the polygon is coaxial with the detection camera 43, so the light source 49 helps to ensure the detection quality, is easy to adjust, and has good adaptability.

[0033] Preferably, the top of the mounting base 20 is further provided with a mounting frame 14; the placement plate 23 is placed inside the mounting frame 14; an expansion sleeve 15 is provided at the edge of the mounting frame 14, and screws are screwed into the expansion sleeve 15, which presses against the edge of the placement plate 23. A second inflatable pad 16 is provided on the edge of the mounting frame 14, and the placement plate 23 is pressed on the second inflatable pad 16. The screws are screwed into the expansion sleeve 15, which presses against the edge of the placement plate 23, so that the placement plate 23 is fixed and will not loosen, making maintenance and replacement very convenient. The second inflatable pad 16 can reduce the impact of vibration on the placement plate 23, which helps to further ensure the accuracy of the detection. The first inflatable pad 13 and the second inflatable pad 16 have the same structure. The expansion sleeve 15 can be made of plastic or silicone material.

[0034] Preferably, the light source 49 is an LED light source 49; the placement plate 23 is one of glass plate, acrylic plate, polyimide, and ceramic plate.

[0035] The combination of the detection camera 43 and the laser sensor 45 offers the following advantages: 1. Expanded measurement range: The camera (lens) covers medium- to long-distance, wide-field contour / position measurement, while the sensor (laser) is suitable for close-range, small-size, or special working conditions (such as high temperature or obstruction). The combined measurement range and working conditions are significantly broadened. 2. Improved lens efficiency: The lens does not need to handle all measurement requirements and can focus on its strengths in visual recognition scenarios (such as contour comparison and positioning), avoiding a decrease in response speed or accuracy due to the need to handle complex physical quantity measurements, thus indirectly improving its own working efficiency. 3. Laser measurement of dimensions that the lens cannot measure: Due to limitations in resolution, depth of field, or obstruction, the lens has difficulty measuring dimensions such as tiny gaps, deep hole depths, and curved surface curvatures; the laser sensor 45, through precise ranging and scanning, can directly obtain quantitative data from these "visual blind spots," perfectly filling the gaps.

[0036] In summary, the key design feature of this invention is that the light source 49 can be adjusted and oscillated on the lamp holder 46, thus allowing for adjustable illumination range, greater flexibility, and convenient adjustment. Simultaneously, the cooperation between the detection camera 43 and the laser sensor 45 expands the measurement range, increases lens efficiency, and enables the laser to measure dimensions inaccessible by the lens, resulting in better measurement accuracy. Dual-station measurement further enhances efficiency.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
