Technical Field

[0001] This invention relates to the field of PCBN tool size inspection technology, specifically to a batch measurement device for PCBN tool size pass rate and its usage method. Background Technology

[0002] Batch measurement devices for PCBN tool size pass rate typically employ optical 3D measurement systems such as Bruker Alicona, combined with automated collaborative measurement platforms (such as CompactCobot), to achieve efficient, non-contact batch inspection of key parameters such as tool size, cutting edge defects, chamfer width and angle, ensuring measurement accuracy at the micrometer level and improving quality control efficiency.

[0003] In the process of inspecting the dimensions of PCBN cutting tools, it is necessary to inspect both sides of the PCBN cutting tool simultaneously to ensure the accuracy of the inspection. If the PCBN cutting tool is clamped and positioned by a fixture during the inspection process, the clamping and positioning position is difficult to detect, resulting in incomplete inspection. Therefore, in order to address the above problem, a batch measurement device for the dimensional pass rate of PCBN cutting tools and its usage method are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a batch measurement device and its method for measuring the dimensional pass rate of PCBN cutting tools, in order to solve the problem that in the process of PCBN cutting tool dimensional inspection, it is necessary to inspect both sides of the PCBN cutting tool simultaneously to ensure the accuracy of the inspection. However, if the PCBN cutting tool is clamped and positioned by a fixture during the inspection process, the clamping and positioning position is difficult to detect, resulting in incomplete inspection.

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

[0006] A batch measurement device for PCBN tool dimensional pass rate and its usage method include a first high-speed camera and a second high-speed camera for detecting the dimensions of PCBN tools. The first high-speed camera is mounted on the upper end of a first conveying unit, and the second high-speed camera is mounted on the upper end of a second conveying unit. The first conveying unit includes a conveyor belt surface. A drive roller is mounted on the inner side of one end of the conveyor belt surface, and two driven rollers are mounted on the inner side of the other end of the conveyor belt surface. A plurality of equidistant protrusions are fixedly connected to the outer side of the conveyor belt surface, and a positioning unit is installed between two adjacent protrusions. The positioning unit includes a positioning shell, and a support assembly is mounted on the positioning shell through a perforation. A control iron block is mounted on the upper end of the support assembly. Sliding grooves are opened at the upper and lower ends of the positioning shell. An electromagnetic suction plate is installed between the driven rollers.

[0007] As a further optimization of the present invention, the following features are provided: both ends of the drive roller and the driven roller are equipped with frames; one side of the drive roller is fixedly connected to the main shaft of the drive motor; the drive motor is mounted on one side of the frame via a housing and bolts; the vertical projection of the driven roller is H-shaped; the top end of one driven roller is on the same horizontal plane as the top end of the drive roller; the bottom end of the other driven roller is on the same horizontal plane as the bottom end of the drive roller; and the center points of the two driven rollers are on the same vertical plane.

[0008] As a further optimization of the present invention, the length of the protrusion is equal to the width of the conveyor belt surface, the protrusion is used to separate the PCBN tool for size detection, multiple positioning units are provided, the positioning units are located at the center plane displacement of the first conveyor unit, and the positioning units are equidistant from each other.

[0009] As a further optimization of the present invention, the support component includes a support slider, one end of which is fixedly connected to a friction pad, the other end of which has an inclined surface, and a return spring is installed on the outside of the support slider.

[0010] As a further optimization of the present invention, the vertical cross-section of the control block is trapezoidal, the control block is located on the upper side of the inclined end of the support slider, and the control block is in close contact with the inclined surface.

[0011] As a further optimization of the present invention, the supporting slider is configured in a "+" shape, and the upper and lower ends of the supporting slider are slidably connected to the positioning shell through a sliding groove. The end of the supporting slider away from the inclined surface is slidably connected to the positioning shell through a perforation, and the perforation is a square hole.

[0012] As a further optimization of the present invention, one end of the reset spring is fixedly connected to the inner wall of the positioning shell, and the other end of the reset spring is fixedly connected to the middle protrusion of the support slider.

[0013] As a further optimization of the present invention, the electromagnetic chuck is U-shaped and is fixedly connected to the support frame by bolts.

[0014] As a further optimization of the present invention, wherein: a sorting component is installed on the upper end of the second conveying unit, the sorting component includes a rotating rod, one end of the rotating rod is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the outer shell of the second conveying unit, the other end of the rotating rod is fixedly connected to a shock-absorbing spring, the other end of the shock-absorbing spring is fixedly connected to a ring plate, and a positioning rod is fixedly connected in the middle of the ring plate; one end of the positioning rod is fixedly connected to the outer shell of the second conveying unit, and the other end of the positioning rod has no contact with the rotating rod.

[0015] As a further optimization of the present invention, it includes the following steps:

[0016] S1. When the equipment is running, it is powered by an external industrial power supply and communicates with the central control console.

[0017] Then, the PCBN tool with a circular hole in the middle is placed outside the positioning unit from one end of the first conveying unit. After placement, the PCBN tool passes under the first high-speed camera to detect the size.

[0018] Those that pass the inspection continue to be conveyed, while those that fail the inspection are removed and recycled manually or by a robotic arm.

[0019] S2. When the qualified PCBN tool passes the outer position of the electromagnetic chuck, the control iron block inside the electromagnetic chuck positioning unit is attracted. At this time, the control iron block moves the support slider away from the center point of the positioning shell through the inclined plane, and controls the friction pad to contact the inner wall of the inner round hole of the PCBN tool.

[0020] S3. When the PCBN tool moves to the bottom of the first conveying unit and leaves the position of the electromagnetic chuck, the support slider is reset by the reset spring. At this time, the PCBN tool falls to the top of the second conveying unit and the other end of the PCBN tool faces upward.

[0021] S4. After the PCBN tool falls to the top of the second conveyor unit, it is conveyed under the second high-speed camera for further dimensional inspection.

[0022] During this process, the rotating rod organizes the PCBN tools that have fallen to different positions on the upper part of the second conveyor unit and moves them to the middle position of the second conveyor unit.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In this invention, by setting a first high-speed camera and a second high-speed camera, during the detection of one end face of the PCBN tool, the positioning unit used for flipping in the middle does not contact the PCBN tool, which can ensure the integrity of the detection of the upper end face. During the detection of the other end face, no fixture is used, and it is directly placed on the upper end of the second conveying unit for detection, which can ensure the integrity of the detection of the other end face, and thus ensure the integrity of the overall detection.

[0025] 2. In this invention, by matching the electromagnetic chuck with the positioning unit, the flipping process of the PCBN tool can be automatically completed during the transfer of the PCBN tool between the first and second transfer units, which is more convenient and stable. At the same time, in actual application, the round hole inside the PCBN tool is used for positioning.

[0026] 3. In this invention, the sorting component can automatically sort the PCBN tools that have fallen to different positions on the upper part of the second conveying unit to the middle position of the second conveying unit, so as to ensure the accuracy of the second high-speed camera in detecting the size of the PCBN tools.

[0040] Please see Figures 1-7 The present invention provides a technical solution:

[0041] A batch measurement device for PCBN tool size qualification rate and its usage method include a first high-speed camera 3 and a second high-speed camera 6 for detecting the size of PCBN tools. The first high-speed camera 3 is installed on the upper end of a first conveying unit 1, and the second high-speed camera 6 is installed on the upper end of a second conveying unit 2. The first conveying unit 1 includes a conveyor belt surface 11. A drive roller 12 is installed on the inner side of one end of the conveyor belt surface 11, and two driven rollers 13 are installed on the inner side of the other end of the conveyor belt surface 11. A plurality of equidistant protrusions 14 are fixedly connected to the outer side of the conveyor belt surface 11, and a positioning unit 15 is installed between two adjacent protrusions 14. The positioning unit 15 includes a positioning shell 151. A support assembly 153 is installed on the positioning shell 151 through a through hole 152. A control iron block 154 is installed on the upper end of the support assembly 153. Sliding grooves 155 are opened at the upper and lower ends of the positioning shell 151. An electromagnetic suction plate 5 is installed between the driven rollers 13.

[0042] As a further implementation of this solution, both ends of the drive roller 12 and the driven roller 13 are equipped with frames. One side of the drive roller 12 is fixedly connected to the main shaft of the drive motor. The drive motor is installed on one side of the frame through the housing and bolts. The vertical projection of the driven roller 13 is H-shaped. The top of one driven roller 13 is set on the same horizontal plane as the top of the drive roller 12, and the bottom of the other driven roller 13 is set on the same horizontal plane as the bottom of the drive roller 12. The center points of the two driven rollers 13 are set on the same vertical plane. With the above settings, the PCBN tool to be detected can be driven stably under the first high-speed camera 3 for detection.

[0043] As a further implementation of this solution, the length of the protrusion 14 is equal to the width of the conveyor belt surface 11. The protrusion 14 is used to separate the PCBN tool for size detection. Multiple positioning units 15 are provided. The positioning units 15 are located at the center plane displacement of the first conveyor unit 1. The positioning units 15 are equidistant from each other. Through the above settings, the PCBN tool can be placed at a fixed distance to ensure the stability and accuracy of the detection process.

[0044] As a further implementation of this solution, the support component 153 includes a support slider 1531. One end of the support slider 1531 is fixedly connected to a friction pad 1533, and the other end of the support slider 1531 is provided with an inclined surface 1534. A return spring 1532 is installed on the outside of the support slider 1531. With the above settings, the PCBN tool conveyed at the upper end of the first conveying unit 1 can be positioned.

[0045] As a further implementation of this solution, the vertical section of the control block 154 is set in a trapezoidal shape. The control block 154 is set on the upper side of the end of the support slider 1531 where the inclined surface 1534 is opened. The control block 154 and the inclined surface 1534 are in close contact. With the above setting, the support slider 1531 can be moved while the control block 154 is attracted by the electromagnetic suction plate 5.

[0046] As a further implementation of this solution, the support slider 1531 is arranged in a "+" shape. The upper and lower ends of the support slider 1531 are slidably connected to the positioning shell 151 through the sliding groove 155. The end of the support slider 1531 away from the inclined surface 1534 is slidably connected to the positioning shell 151 through the through hole 152. The through hole 152 is a square hole. Through the above arrangement, the stability of the support slider 1531 during the movement process can be further improved.

[0047] As a further implementation of this solution, one end of the reset spring 1532 is fixedly connected to the inner wall of the positioning shell 151, and the other end of the reset spring 1532 is fixedly connected to the middle protrusion of the support slider 1531. With the above arrangement, it is easy to control the support slider 1531 to reset.

[0048] As a further implementation of this solution, the electromagnetic chuck 5 is U-shaped and is fixedly connected to the support frame 4 by bolts. With the above settings, the electromagnetic chuck 5 can be stably positioned.

[0049] As a further implementation of this solution, a sorting component 7 is installed on the upper end of the second conveying unit 2. The sorting component 7 includes a rotating rod 71. One end of the rotating rod 71 is fixedly connected to a rotating shaft 72. The rotating shaft 72 is rotatably connected to the outer shell of the second conveying unit 2. The other end of the rotating rod 71 is fixedly connected to a shock-absorbing spring 75. The other end of the shock-absorbing spring 75 is fixedly connected to a ring plate 74. A positioning rod 73 is fixedly connected in the middle of the ring plate 74.

[0050] As a further implementation of this solution, one end of the positioning rod 73 is fixedly connected to the outer shell of the second conveying unit 2, and the other end of the positioning rod 73 is not in contact with the rotating rod 71. With the above setting, the PCBN tools that have fallen to different positions on the upper part of the second conveying unit 2 can be organized to the middle position of the second conveying unit 2 to ensure the accuracy of the second high-speed camera 6 in detecting the size of the PCBN tools.

[0051] As a further implementation of this solution, the technical solution includes the following steps:

[0052] S1. When the equipment is running, it is powered by an external industrial power supply and communicates with the central control console.

[0053] Then, the PCBN tool with a circular hole in the middle is placed from one end of the first conveying unit 1 to the outside of the positioning unit 15. After placement, the PCBN tool passes under the first high-speed camera 3 to detect the size.

[0054] Those that pass the inspection continue to be conveyed, while those that fail the inspection are removed and recycled manually or by a robotic arm.

[0055] S2. When the qualified PCBN tool passes the outer position of the electromagnetic suction plate 5, the control iron block 154 inside the positioning unit 15 of the electromagnetic suction plate 5 is attracted. At this time, the control iron block 154 moves the support slider 1531 away from the center point of the positioning shell 151 through the inclined surface 1534, and controls the friction pad 1533 to contact the inner wall of the inner round hole of the PCBN tool.

[0056] S3. When the PCBN tool moves below the first conveying unit 1 and leaves the position of the electromagnetic chuck 5, the support slider 1531 is reset under the action of the reset spring 1532. At this time, the PCBN tool falls to the upper end of the second conveying unit 2 and the other end of the PCBN tool faces upward.

[0057] S4. After the PCBN tool falls to the top of the second conveying unit 2, it is conveyed past the second high-speed camera 6 for further size detection.

[0058] During this process, the rotating rod 71 organizes the PCBN tools that have fallen to different positions on the upper part of the second conveying unit 2 and moves them to the middle position of the second conveying unit 2.
