Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a flatness testing instrument with a ring-shaped shadowless light source. Background Technology

[0002] Industrial robot vision flatness testing instruments are non-contact inspection devices that integrate machine vision, laser sensing, and precision motion control technologies. They often work in conjunction with industrial robots to efficiently and accurately inspect the flatness of various workpieces. Flatness testing instruments with ring-shaped shadowless light sources are based on the principle of optical imaging. They utilize a ring-shaped shadowless light source to uniformly illuminate the surface of the object being measured, and in conjunction with an image acquisition and analysis system, achieve accurate measurement of flatness.

[0003] Existing flatness testing instruments with ring-shaped shadowless light sources are troublesome to use because the flatness testing probes are usually fixed with bolts, making the assembly and disassembly process cumbersome. Traditional tools are prone to deformation of the connection with the robotic arm due to improper force during disassembly, and the probe lens and light source assembly are easily damaged by bumps. In addition, the light is not easy to evenly cover the testing surface of workpieces of different sizes and placement positions, which limits the detection range of the light source. Custom light source brackets are required for workpieces of different specifications, which greatly increases the equipment manufacturing cost. Utility Model Content

[0004] This utility model relates to a flatness testing instrument with a ring-shaped shadowless light source. By manually squeezing the two elastic buckles in opposite directions, the elastic buckles lose their engagement with the rectangular slot of the positioning groove. Then, the flatness testing probe is pulled downward, causing the fixed seat to slide out of the through hole along with the limiting post. This allows the flatness testing probe to be quickly removed from the robotic arm. The entire disassembly process does not require tools, improving the disassembly efficiency of the flatness testing probe and avoiding damage to the precision components of the testing probe and the connecting structure of the robotic arm caused by tools or external impacts.

[0005] This utility model provides a flatness testing instrument with a ring-shaped shadowless light source, specifically including: a robotic arm, with a mounting frame at the end of the robotic arm; a flatness testing probe below the mounting frame; a fixed base at the top of the flatness testing probe, and the fixed base is connected to the mounting frame; an operating table is provided on the right side of the robotic arm, and the flatness testing probe is located above the operating table; a supporting column is provided on the top right side of the operating table; an adjusting frame is provided on the supporting column; and a ring-shaped shadowless light source is provided below the adjusting frame.

[0006] Furthermore, the mounting bracket is provided with a positioning groove and two through holes, which are distributed symmetrically.

[0007] Furthermore, the flatness detection probe is provided with a connecting post at the top, and a transmission line is provided at the top of the connecting post.

[0008] Furthermore, the bottom of the fixing seat is provided with a connecting sleeve, and the connecting column is fixedly installed in the connecting sleeve. The top of the fixing seat is provided with two elastic buckles and two limiting columns. When the fixing seat and the mounting frame are connected, the elastic buckles engage with the rectangular slot of the positioning groove, and the limiting columns slide through the through hole.

[0009] Furthermore, the right end of the adjustment frame is provided with a limiting slide sleeve, and the front of the limiting slide sleeve is provided with a locking knob. The limiting slide sleeve is fitted onto the support column and is controlled by the locking knob.

[0010] Furthermore, the adjustment frame is provided with a limiting through groove, and a lead screw is provided at the rear of the adjustment frame. The lead screw is rotatably connected to the adjustment frame through a bearing bracket. A servo motor is fixedly installed at the rear of the adjustment frame, and the rotating shaft of the servo motor is connected to the lead screw.

[0011] Furthermore, the annular shadowless light source is provided with a connecting seat, and a limiting sleeve is provided at the rear of the connecting seat. The connecting seat is slidably connected to the adjusting frame through the limiting sleeve. A limiting slider is provided at the middle position of the rear of the connecting seat. A threaded sleeve is provided at the rear end of the limiting slider. The limiting slider is set in the limiting through groove, and the threaded sleeve is fitted onto the lead screw.

[0012] This utility model provides a flatness testing instrument with a ring-shaped shadowless light source, which has the following beneficial effects: This utility model features a mounting bracket and a fixed base. By manually squeezing the two elastic buckles in opposite directions, the elastic buckles lose their engagement with the rectangular slot of the positioning groove. Then, the flatness detection probe is pulled downwards, causing the fixed base to slide the limiting post down through the through hole. This allows the flatness detection probe to be quickly removed from the robotic arm. The entire disassembly process requires no tools, improving the disassembly efficiency of the flatness detection probe and avoiding damage to the precision components of the detection probe and the connecting structure of the robotic arm caused by tools or external impacts.

[0013] Furthermore, this invention is powered by a servo motor, which, through the transmission of a lead screw and a threaded sleeve, allows the connecting seat to drive the annular shadowless light source to slide left and right along the limiting groove. The horizontal position of the annular shadowless light source can be automatically adjusted according to the workpiece of different sizes and placement positions, ensuring that the light source is always facing the workpiece detection area and that the light uniformly covers the detection surface. Moreover, there is no need to customize a special light source bracket for workpieces of different specifications, which greatly expands the detection application range of the equipment.

[0020] In this embodiment, as Figure 2 and Figure 3 As shown, the mounting bracket 2 is provided with a positioning groove 201 and two through holes 202, which are distributed symmetrically. The flatness detection probe 3 is provided with a connecting post 301 at the top, and a transmission line 302 is provided at the top of the connecting post 301; The bottom of the fixed base 4 is provided with a connecting sleeve 401, and the connecting post 301 is fixedly installed in the connecting sleeve 401. The top of the fixed base 4 is provided with two elastic buckles 402 and two limiting posts 403. When the fixed base 4 is connected to the mounting frame 2, the elastic buckles 402 are engaged with the rectangular slot of the positioning groove 201, and the limiting posts 403 slide through the through hole 202. Since this utility model is provided with a mounting frame 2 and a fixed base 4, by manually squeezing the two elastic buckles 402 in opposite directions, the elastic buckles 402 lose their engagement with the rectangular slot of the positioning groove 201. Then, the flatness detection probe 3 is pulled down, so that the fixed base 4 drives the limiting posts 403 to slide down from the through hole 202, thereby allowing the flatness detection probe 3 to be quickly removed from the robot arm 1.

[0021] Example 2, based on Example 1, such as Figure 4 and Figure 5 As shown, the adjustment frame 7 is provided with a limiting through groove 703, and the rear of the adjustment frame 7 is provided with a lead screw 704. The lead screw 704 is rotatably connected to the adjustment frame 7 through a bearing frame.

A limiting sleeve 802 is provided at the rear of the connecting seat 801, and the connecting seat 801 is slidably connected to the adjusting frame 7 through the limiting sleeve 802. A limiting slider 803 is provided at the middle of the rear of the connecting seat 801. A threaded sleeve 804 is provided at the rear end of the limiting slider 803. The limiting slider 803 is set in the limiting through groove 703, and the threaded sleeve 804 is fitted on the lead screw 704. In this utility model, the power is provided by a servo motor 705. Through the transmission cooperation of the lead screw 704 and the threaded sleeve 804, the connecting seat 801 can drive the annular shadowless light source 8 to slide left and right along the limiting through groove 703. The horizontal position of the annular shadowless light source 8 can be automatically adjusted according to the workpiece of different size and placement position, so that the light source is always facing the workpiece detection area.

[0022] The working principle of this embodiment is as follows: In use, by manually pinching the two elastic buckles 402 in opposite directions, the elastic buckles 402 lose their engagement with the rectangular slot of the positioning groove 201. Then, the flatness detection probe 3 is pulled down, causing the fixed seat 4 to slide the limiting post 403 down from the through hole 202, thereby allowing the flatness detection probe 3 to be quickly removed from the robot arm 1. Powered by the servo motor 705, the connecting seat 801 can drive the annular shadowless light source 8 to slide left and right along the limiting through groove 703 through the transmission cooperation of the lead screw 704 and the threaded sleeve 804. The horizontal position of the annular shadowless light source 8 can be automatically adjusted according to the workpiece of different size and placement position, so that the light source is always facing the workpiece detection area.
