Description

Technical Field

[0001] The utility model relates to the technical field of edge finders, in particular to a 3D photoelectric edge finder. Background Art

[0002] As an advanced measurement tool, the 3D edge finder is designed based on the traditional 2D edge detection technology, but has been significantly improved and expanded on this basis. It combines modern electronic technology, precision mechanical design and advances in materials science to meet the needs of the industrial field for efficient and accurate spatial measurement. In the early 2D edge detection technology, optical or mechanical sensors were mainly relied on to identify the contours of the object surface. However, these technologies are limited when dealing with complex shapes or three-dimensional objects because they cannot provide depth information. With the development of computer-aided manufacturing (CAM) and computer-aided design (CAD) technology, the demand for three-dimensional spatial data is growing, which has promoted the birth and development of 3D edge finder technology. The core advantage of the 3D edge finder is its ability to quickly locate the edge of an object in three-dimensional space. By using a precise probe system, it can measure in multiple directions to build a three-dimensional model of the object. This capability is particularly important in complex processing environments, such as CNC processing, where accurate workpiece positioning is a key step to ensure processing quality. In addition, the 3D edge finder is also highly flexible and adaptable, and can adapt to workpieces of different sizes and shapes, as well as the detection of various materials.

[0003] In modern manufacturing, the application of automation and robotics technology is becoming more and more widespread. 3D edge finders can be installed on the manipulator of machine tools to achieve automated detection and positioning, and improve production efficiency and accuracy. In addition, the flexibility of robotics technology enables edge finders to perform all-round measurements on workpieces with complex shapes and adapt to diverse processing needs.

[0004] In the prior art, when using an edge finder, only the center point of the metal material can be found, and the operator cannot perceive the center position of the measured object in a timely and intuitive manner; therefore, we have made improvements to this and proposed a 3D photoelectric edge finder.

One end of the dustproof pad 8 is pressed on the base 9, and the other end of the dustproof pad 8 is wrapped around the upper end of the measuring needle seat 10.

[0043] The shape of the stylus body 7 can be: a T-shaped stylus, a hook-shaped stylus rod, etc. Stylus of different shapes can be replaced for measurement according to different measurement scenarios.

[0045] By using the principle of opposite poles of magnets repelling each other, the stylus body 7 can be accurately returned to its original position each time a measurement is made, and when the measurement is completed, the centers of the stylus base 10 and the fixing base 11 can be synchronized in time to prevent deviation, so that the detection result is more standardized;

[0046] During the installation process, the electrode holder 13, the integrated circuit board 12 and the fixing holder 11 are connected and positioned by fine thread grooves and fine screws to ensure stability and concentricity among the three.

[0047] When the probe moves, the induction column 24 and the steel ball 21 are offset, thereby generating an electromagnetic signal to trigger the induction lamp connected to the integrated circuit board 12 to light up and the buzzer 26 to sound;

[0048] In the lighting operation, in the setting of the integrated circuit board 12, for different sensing columns 24 when moving, the RGB light sensing mode is used to intuitively monitor the color mark of each measurement point set on the measured object through the three-primary color mixing effect. The object measured by the device, such as: wooden products, is sensed by the measuring needle body 7.

[0049] like Figure 7 As shown, as a preferred embodiment, on the basis of the above method, further, the lower end of the fixing seat 11 and the integrated circuit board 12 are attached to each other, the inner end of the fixing seat 11 is connected through the pin hole 19, the number of the pin holes 19 is set to three groups, each group of pin holes 19 is provided with two, and the six pin holes 19 slide with the step pin 18 respectively, the lower end of the step pin 18 is movably connected with the compression spring 20, the upper end of the step pin 18 is in contact with the steel ball 21, the steel ball 21 is embedded in the ball groove 22, the pin hole 19 is connected through the sensing groove 23, the sensing groove 23 is embedded and installed on the inner surface of the upper end of the fixing seat 11, the sensing groove 23 is wrapped around the outer end of the steel ball 21 and the sensing column 24, and the sensing column 24 is located at the upper end of the probe seat 10.

[0050] Through the step pin 18, when the corresponding sensing column 24 collides with the corresponding steel ball 21 during use, the compression spring 20 at the lower end of the step pin 18 contacts the contact point on the integrated circuit board 12, thereby triggering the induction;

[0051] The three groups of pin holes 19 correspond to the three groups of step pins 18 arranged in a circular array along the fixing seat 11, and the three groups of step pins 18 are in contact with the steel balls 21 respectively, and every two steel balls 21 are in contact with a group of sensing columns 24. Such an arrangement can facilitate the device body to quickly measure the center position of the measured object during measurement.

[0054] Furthermore, the waterproof sealing ring 14 is defined between the main clamping handle 5 and the main body 2, so that the overall sealing performance inside can be guaranteed to a great extent.

[0055] like Figure 4 As shown, as a preferred embodiment, based on the above method, further, two groups of battery bodies 15 are provided at the inner end of the main clamping handle 5, and copper sheets are provided at the upper ends of the two groups of battery bodies 15, and the copper sheets are connected to the integrated circuit board 12 through wires.

[0056] By providing the copper sheet, the two groups of battery bodies 15 can conveniently supply power to the trigger structure at the upper end, and the power supply can be smoothly transmitted.

[0057] When the present application is in use: the material to be processed (metallic material and non-metallic material) is placed on the machine tool, and the main body of the device is installed on the manipulator (through the connection of the manipulator, the stability and standardization of the measurement can be guaranteed). Corresponding to the gripping depth that different manipulators can adapt to, we use replaceable battery back covers 17 with handles and battery back covers 16 without handles. When measuring, the probe body 7 of the main body of the device contacts the surface of the object to be measured, such as rubber parts, to produce contact, and the starting point is first determined using the probe body 7, and the color of the sensor light tends to be red; then the second point is selected using the probe body 7, and the color of the sensor light tends to be green; the third point is selected using the probe body 7, and the color of the sensor light tends to be blue; the probe system calculates the center point position, and moves the probe body 7 to the center point position of the measurement, then The light color of the induction lamp tends to be white. During the contact process, the probe body 7 moves along the base 9 and the probe seat 10, and in the process of movement, the magnetic attraction structure between the fixed seat 11 and the probe seat 10 can push the corresponding induction column 24 to contact and push the steel balls 21 on both sides, and then connect the compression spring 20 through the step pin 18 connected to the lower end of the corresponding steel ball 21, and push the compression spring 20 and the electric shock on the integrated circuit board 12 to sense each other. By utilizing the activities of the six step pins 18, the signal is transmitted on the integrated circuit board 12, and the induction lamp senses it. The color of the light is observed through the photosensitive slot 25 and the acrylic ring 3, and the buzzer 26 sounds, so that the operator can quickly and intuitively find the position of the center point and mark the color of the detection point to avoid operating errors that cause center point measurement errors.
