[0029] In the batch production process of PCB drill bit, the grinding step needs to be carried out on the machine tool, the drill bit is positioned by the clamps in X direction and Y direction on the machine tool, and the feed of the drill bit along its axial and radial directions is realized, and the grinding is carried out by cooperating with the rotation of the grinding wheel. There is a difficulty in the drill diameter fine grinding process that the drill diameter gradually decreases with the feed of the grinding wheel, and the clamps in X direction and Y direction also need to follow the synchronous feed to ensure that the drill bit does not move, prevent the grinding wheel from being damaged, and ensure the processing accuracy of the drill bit. However, the existing machine tool lacks corresponding tools to detect whether the clamps in X direction and Y direction keep synchronous feeding for a long time, and the processing condition of the drill bit cannot be judged.
[0030] Therefore, the present embodiment provides a visual detection mechanism, which is installed in the machine tool and can detect whether the clamps in X direction and Y direction on the machine tool keep synchronous feeding in real time, so as to facilitate the judgment of the processing condition of the drill bit and provide basis for the subsequent adjustment of the clamps.
[0031] Specifically, as shown in Figure 1 The visual detection device includes a mounting seat 1, a connecting piece 2 and a visual detection piece 3, the mounting seat 1 is configured to be fixed in the machine tool, one end of the connecting piece 2 is connected to the mounting seat 1, the other end of the connecting piece 2 is connected with the visual detection piece 3, and the visual detection piece 3 is used to detect whether the clamps in X direction and Y direction on the machine tool keep synchronous feeding.
[0032] The visual detection mechanism provided by the embodiment is installed in the machine tool through the mounting base 1. During the polishing of the drill, the visual detection member 3 can capture the fixture pictures in the X direction and the Y direction before and after the drill diameter processing, and the video whether the drill is clamped synchronously, and can be connected to the terminal through the data line to synchronously view the shooting situation. According to the comparison of the before and after pictures and the corresponding video, whether the fixtures in the X direction and the Y direction on the machine tool keep synchronous feeding can be judged, so that the processing condition of the drill can be judged. When the fixtures in the X direction and the Y direction do not keep synchronous feeding, the processed drill is judged as unqualified product, and basis can be provided for subsequent adjustment of the fixture. When the fixtures in the X direction and the Y direction keep synchronous feeding, the processed drill is judged as a good product, and the operation is convenient.
[0033] In the embodiment, the visual detection member 3 is an electron microscope, specifically a portable digital microscope. Since the internal space of the machine tool is not large, the volume of such a microscope is small, which is suitable for use in the narrow space of the machine tool.
[0034] In other embodiments, if the space in the machine tool allows, the visual detection member 3 can also use an industrial CCD camera.
[0035] Further, the connecting member 2 is a metal hose. In this way, by arranging the metal hose, the operator can adjust the electron microscope arranged at the end of the metal hose at any angle and direction to make the lens of the electron microscope face any position, so that the detection range can be accurately positioned, and the use is convenient.
[0036] Further, as shown in Figure 1 The end of the metal hose away from the mounting base 1 is fixed with a mounting clamp 4, and the mounting clamp 4 is used to clamp the visual detection member 3. By arranging the mounting clamp 4, the stable installation of the visual detection member 3 can be realized, and the disassembly and assembly of the electron microscope are more convenient and fast.
[0037] Specifically, the metal hose includes a pipe body 21 and first and second connecting parts 22 and 23 connected to both ends of the pipe body 21 respectively, wherein the pipe body 21 can be bent at any angle and in any direction, the first connecting part 22 is connected with the mounting base 1, and the second connecting part 23 is connected with the mounting clamp 4.
[0038] In an optional embodiment, the first connecting part 22 is threadedly connected with the mounting base 1. Specifically, a threaded hole is formed on one side of the first connecting part 22 close to the mounting base 1, and a screw hole is formed on the mounting base 1. The threaded hole is threadedly connected with the screw hole. By screwing the first connecting part 22, the connection between the first connecting part 22 and the mounting base 1 can be realized. This connection is stable and convenient to disassemble and assemble.
[0039] In an optional embodiment, the second connecting portion 23 is threadedly connected with the mounting clamp 4. Specifically, a threaded stud is formed on the side of the mounting clamp 4 close to the second connecting portion 23, and a threaded hole is formed on the second connecting portion 23, and the threaded stud is threadedly connected with the threaded hole. The connection between the second connecting portion 23 and the mounting clamp 4 can be achieved by screwing the mounting clamp 4. This way of connection is stable and convenient to disassemble and assemble.
[0040] Further, as shown in Figure 1 the mounting base 1 comprises a base 11, an XY-axis manual sliding table 12 and a top base 13, the base 11 is fixed to the bottom side of the XY-axis manual sliding table 12, and the top base 13 is fixed to the top side of the XY-axis manual sliding table 12 and connected with the connecting piece 2. By arranging the XY-axis manual sliding table 12, the shooting position of the visual detection piece 3 can be finely adjusted, and in combination with the above-mentioned metal hose, the lens of the visual detection piece 3 can be directed to any position, and thus the detection range can be accurately positioned. The specific structure and working principle of the XY-axis manual sliding table 12 are both prior art, and thus will not be described here.
[0041] Further, as shown in Figure 1 the mounting base 1 further comprises a magnetic base 14, the magnetic base 14 is fixed to the bottom side of the base 11, and the magnetic base 14 can be magnetically attracted to the inside of the machine tool. By magnetic attraction, the magnetic base can be quickly connected with and separated from the machine tool, saving time and labor, and the connection is stable, and the magnetic base can be repeatedly used and is not easy to be damaged.
[0042] Further, as shown in Figure 1 the side surface of the magnetic base 14 is provided with a knob 15, and by rotating the knob 15, the magnetic base 14 can be magnetically attracted to the machine tool or the magnetic connection with the machine tool can be released. Specifically, the magnetic base 14 has a long strip-shaped permanent magnet inside, and the bottom position of the magnetic base 14 is a soft magnetic material (the soft magnetic material refers to a kind of ferrite material which is easy to magnetize and demagnetize under a weak magnetic field), and the inside permanent magnet is rotated by rotating the knob 15. When the two poles of the permanent magnet are in the up-down direction, that is, the N or S pole of the permanent magnet is directly opposite to the soft magnetic material at the bottom, the soft magnetic material is magnetized, and at this time, the soft magnetic material can stably attract the surface of the machine tool; when the two poles of the permanent magnet are in the horizontal direction, and the N pole and the S pole are directly opposite to the soft magnetic material (the middle of the long strip-shaped permanent magnet has only a small magnetism, which can be ignored), the soft magnetic material will not be magnetized, so at this time, the bottom of the magnetic base 14 has almost no magnetic force, and the magnetic base 14 can be easily taken off from the surface of the machine tool, which is convenient to operate. The specific structure inside the magnetic base 14 is prior art, and thus will not be described here.
[0043] In summary, the visual detection mechanism provided in the embodiment is used in the following way: the magnetic seat 14 is first magnetically adsorbed on the machine tool, then the electron microscope is moved to the area to be detected by operating the metal hose, then the position is accurately adjusted by the XY-axis manual sliding table 12, and finally the magnification of the electron microscope is adjusted to make the image clear.
[0044] The embodiment also provides a drill bit polishing device, which comprises the machine tool and the visual detection mechanism.
[0045] The drill bit polishing device provided in the embodiment can capture the pictures of the X-direction and Y-direction clamps before and after the drill diameter processing and the video of whether the drill bit is synchronously clamped by the visual detection member 3, and the shooting situation can be synchronously viewed by being connected to the terminal through a data line.
[0046] Obviously, the above embodiment of the utility model is only an example for clearly explaining the utility model, and is not a limitation on the implementation mode of the utility model. For ordinary skilled persons in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the utility model. It is unnecessary and impossible to exhaust all the implementation modes.
