Abstract
Description
Technical Field
[0001] This invention relates to the field of diamond wire manufacturing equipment technology, and in particular to a visual inspection component for detecting the distribution of diamond grit on diamond wire. Background Technology
[0002] Diamond cutting wire, also known as diamond wire, usually refers to a diamond sawing wire made by electroplating a layer of nickel or nickel-cobalt alloy onto the surface of a metal baseline, while diamond abrasive mixed in the plating solution is fixed in the nickel or nickel-cobalt alloy layer of the metal baseline.
[0003] Currently, diamond wire is manufactured using electroplating and then wound up using a winding roller. During this process, the quality of the diamond wire needs to be tested to check whether the distribution density of the diamond particles is uniform. However, the traditional testing method is relatively simple: a camera module magnifies the surface distribution of the diamond particles, and staff judge it with the naked eye based on the transmitted images.
[0004] It is still not convenient to use, requiring workers to pay close attention to the transmitted screen at all times. If the worker's attention is diverted, the screen may be missed. Summary of the Invention
[0005] To address the issue that traditional diamond wire surface distribution detection relies on manual identification, which is prone to oversight due to worker negligence. The technical solution provided by this invention is as follows: A visual inspection component for detecting the distribution of diamond grit on diamond wire, which detects the surface distribution of diamond wire, includes two bases arranged in a front-to-back manner. Multiple detection modules and an image transmission module are installed on the front base, and the detection modules are electrically connected to the image transmission module. Two detection modules and an image capture module are installed on the rear base.
[0006] The multiple detection modules are arranged equidistantly along the routing direction. Each detection module includes a ring, multiple beam emitting units, multiple receivers, a toothed ring, and a slide rail bracket. The beam emitting units and receivers are installed inside the ring, and the multiple beam emitting units correspond one-to-one with the multiple receivers. The beam emitting units emit light that irradiates the working surface of the receivers perpendicularly. A diamond wire passes between the beam emitting units and the receivers. The toothed ring is located outside the ring, and the toothed ring and the ring are arranged in concentric circles.
[0007] The slide rail brackets are symmetrically arranged on both sides of the ring. The slide rail brackets slide in conjunction with the ring. The diamond wire passes through the center of the ring, and the ring can rotate around the center. The working end of the image transmission module is electrically connected to a wire, which is electrically connected to the receiver.
[0008] The light emitted by the beam emitting unit passes through the diamond wire and forms a clear shadow area on the working surface of the receiver. The area of the shadow area is the same as the area blocked by the diamond wire.
[0009] The receiver's working surface is equipped with multiple tiny light-capturing units, which are used to sense the size of the shadow area.
[0010] Two detection modules are arranged sequentially along the wiring direction. The diamond wire can pass through the detection module. The detection module includes a base post, a slide rod, and a contact plate. The front end of the base post faces the diamond wire. The base posts are distributed at equal angles in a ring with the diamond wire as the center. The end of the slide rod slides into the base post and can be retracted into the base post. The front end of the slide rod is connected to the contact plate. The inner side of the contact plate is provided with a probe for contacting the surface of the diamond wire.
[0011] It also includes a frame, a micro-motion pressure sensor, and a thin spring. The frame is stacked sequentially along the wiring direction. The base column is connected to the frame. The micro-motion pressure sensor is installed at the front end of the base column. The contact piece and the micro-motion pressure sensor are connected by a thin spring.
[0012] The contact piece has an arc-shaped curved surface, and a thin spring is sleeved on the outside of the slide rod.
[0013] The image capture module is installed between the two detection modules. The image capture module is used to capture the surface condition of the diamond and transmit the image to the outside world.
[0014] It also includes a motor, which is mounted on the front base. The motor drive shaft is connected to a gear, which meshes with a gear ring.
[0015] The base is equipped with multiple traction wheels on its top. The diamond wire passes through the multiple traction wheels in sequence along the wire routing direction. The base is equipped with a slide rail, and an auxiliary camera is installed on the slide rail with the working end of the auxiliary camera facing downwards towards the diamond wire.
[0016] The beneficial effects of the technical solution provided by this invention include:
[0017] 1. The system comprises a base, detection module one, image transmission module, detection module two, and image capture module. Detection module one consists of a ring, a beam emitting unit, a receiver, and a light capturing unit. Utilizing the principle of shadows created by light obstruction, it calculates the area of the shadow region to determine the surface density of the diamond wire. This replaces the traditional method of relying on image capture to assist manual visual observation, improving the accuracy of detection and identification while reducing the labor intensity of workers.
[0018] 2. Detection module two consists of a frame, base column, slide bar, contact plate, probe, micro-motion pressure sensor, and fine spring. The probe slides along the surface of the diamond wire to sense its microscopic undulations. The up-and-down movement of the probe applies pressure to the micro-motion pressure sensor, and the density distribution on the diamond wire surface is calculated based on the pressure changes. By establishing multiple detection methods, the applicability of the device is improved, further enhancing its detection capabilities. Attached Figure Description

[0021] A visual inspection component for detecting the distribution of diamond grit on diamond wires, which detects the surface distribution of diamond wires, includes two bases 1, which are arranged one behind the other. Multiple detection modules 2 and an image transmission module 3 are fixedly installed on the front base 1. The detection modules 2 and the image transmission module 3 are electrically connected. Two detection modules 4 and an image capture module 5 are fixedly installed on the rear base 1.
[0022] Multiple detection modules 2 are arranged at equal intervals along the routing direction. Each detection module 2 includes a ring 21, multiple beam emitting units 22, multiple receivers 23, a toothed ring 24, and a slide rail bracket 25. The beam emitting units 22 and receivers 23 are fixedly installed inside the ring 21, with each beam emitting unit 22 corresponding to one of the multiple receivers 23.
[0023] The beam emitting unit 22 emits light that shines perpendicularly onto the working surface of the receiver 23. A diamond wire passes between the beam emitting unit 22 and the receiver 23. A toothed ring 24 is welded to the outside of the ring 21. The toothed ring 24 and the ring 21 are arranged in concentric circles.
[0024] The slide rail brackets 25 are symmetrically arranged on both sides of the ring 21. The slide rail brackets 25 slide in conjunction with the ring 21, and the slide rail brackets 25 are fixedly installed on the front base 1. A diamond wire passes through the center of the ring 21, and the ring 21 can rotate around the center. The working end of the image transmission module 3 is electrically connected to a wire 31, and the wire 31 is electrically connected to the receiver 23.
[0025] The light emitted by the beam emitting unit 22 passes through the diamond wire and forms a clear shadow area on the working surface of the receiver 23. The area of the shadow area is the same as the area blocked by the diamond wire.
[0026] Multiple tiny light-capturing units 231 are fixedly installed in a matrix arrangement on the working surface of the receiver 23. The light-capturing units 231 are used to sense the size of the shadow area.
[0027] Combined with appendix Figure 5 Working principle: The light emitted by the beam emitting unit 22 is partially blocked by the diamond wire, thus forming a strip-shaped shadow area on the working surface of the receiver 23. Since the light is perpendicular to the beam, the area of the shadow area is the same as the cross-section of the diamond wire. The size of the shadow area is sensed by the light capturing unit 231.
[0028] If the diamond particles on the surface of the diamond wire are not evenly distributed, the area of the shadowed region will be small or there will be gaps, resulting in the number of light-blocking and capturing units 231 not meeting the standard. If the diamond particles on the surface of the diamond wire are evenly distributed, there will be no obvious gaps in the shadowed region, and the number of light-blocking and capturing units 231 will meet the standard.
[0029] Detection module 1 (2) and detection module 2 (4) represent two different detection methods. The two detection modules 2 (4) are arranged sequentially along the wiring direction, and the diamond wire can pass through the detection module 2 (4). The detection module 2 (4) includes a base post 42, a slide rod 43, and a contact piece 44.
[0030] The front end of the base post 42 faces the diamond wire, and the base posts 42 are distributed at equal angles in a ring around the diamond wire. The end of the slide rod 43 is slidably engaged with the base post 42, and the slide rod 43 can be retracted into the base post 42. The front end of the slide rod 43 is welded to the contact piece 44, and a probe 441 for contacting the surface of the diamond wire is welded to the inner side of the contact piece 44.
[0031] It also includes a frame 41, a micro-motion pressure sensor 45, and a thin spring 46. The frame 41 is stacked sequentially along the wiring direction and is fixedly installed to the rear base 1. The base column 42 is welded to the frame 41. The micro-motion pressure sensor 45 is fixedly installed at the front end of the base column 42, and the contact piece 44 is fixedly connected to the micro-motion pressure sensor 45 by the thin spring 46.
[0032] The contact piece 44 has an arc-shaped curved surface, and the thin spring 46 is sleeved on the outside of the slide rod 43.
[0033] Working principle: The diamond wire passes through the frame 41. With the help of the spring 46, the contact piece 44 always has a force close to the diamond wire, ensuring that the probe 441 is always in contact with the surface of the diamond wire. During the uniform movement of the diamond wire, The probe 441 slides at a constant speed along the surface of the diamond wire, sensing the microscopic undulations of the surface (protrusions of diamond particles and troughs in the coating). The up-and-down movement of the probe 441 causes the thin spring 46 to extend and retract, thereby applying different pressures to the micro-motion pressure sensor 45. The micro-motion pressure sensor 45 converts the mechanical displacement signal of the probe 441 into an electrical signal and transmits it to an external computer terminal. After processing by the computer, three-dimensional surface morphology data is obtained. The diamond particle distribution density is then calculated. Since the calculation method is a conventional technique, the specific calculation method is not described in detail.
[0034] The image capture module 5 is positioned between the two detection modules 4 and is fixedly installed on the rear base 1. The image capture module 5 captures the surface condition of the diamond and transmits the image to an external computer. The cooperation between the image capture module 5 and the detection modules 4 facilitates the calculation of diamond particle density distribution, improving the ability to test the density distribution of metallic diamond particles on the surface of diamond wire.
[0035] It also includes a motor 26, which is fixedly mounted on the top of the front base 1. A gear 27 is welded to the drive shaft of the motor 26, and the gear 27 meshes with the gear ring 24. This controls the forward and reverse rotation of the ring 21.
[0036] Multiple traction wheels 11 are fixedly installed on the top of the base 1. The diamond wire passes through the multiple traction wheels 11 in sequence along the wire routing direction. A slide rail is fixedly installed on the top of the base 1, and an auxiliary camera 12 is installed on the slide rail with its working end facing down towards the diamond wire. The auxiliary camera 12 is used to assist in capturing the protrusion status of the diamond wire.
[0037] The system comprises a base 1, a detection module 1 2, an image transmission module 3, a detection module 2 4, and a video capture module 5. Detection module 1 2 consists of a ring 21, a beam emitting unit 22, a receiver 23, and a light capturing unit 231. Utilizing the principle of shadow formation due to light obstruction, the system calculates the area of the shadow region to determine the surface density of the diamond wire. This replaces the traditional method of relying on video capture to assist manual visual observation, improving the accuracy of detection and identification while reducing the labor intensity of workers.
[0038] Detection module 2 (4) consists of a frame 41, a base column 42, a slide bar 43, a contact piece 44, a probe 441, a micro-motion pressure sensor 45, and a thin spring 46. The probe 441 slides along the surface of the diamond wire to sense its microscopic undulations. The up-and-down movement of the probe 441 applies pressure to the micro-motion pressure sensor 45, and the density distribution on the diamond wire surface is calculated based on the pressure changes. By establishing multiple detection methods, the applicability of the device is improved, further enhancing its detection capabilities.
[0039] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
