Description

Technical Field

[0001] This invention relates to the field of laser inspection technology, specifically to a laser inspection fixture and method for multi-wire cut workpieces. Background Technology

[0002] Multi-wire cutting, also known as wire cutting, is a machining method that was developed based on electrical discharge machining (EDM) for drilling and forming. It uses a moving metal wire (molybdenum wire, copper wire, or alloy wire) as an electrode wire. The pulsed electric spark discharge between the electrode wire and the workpiece generates high temperature, which melts or vaporizes the metal and forms a kerf, thereby cutting out the part.

[0003] Before cutting, existing wire EDM machines typically need to check the tension of the molybdenum wire or other electrode wires on the spool. Some use laser sensors, while others use handheld rollers to ensure the tension of the molybdenum wire and maintain a stable state for fast or slow wire cutting. However, during fast wire cutting, the temperature of the molybdenum wire gradually increases due to the long-term high-speed transmission of the electrode wire. This causes the molybdenum wire to degrade in performance, reduce tensile strength, and increase brittleness, thereby increasing the risk of breakage. Furthermore, the high temperature of the molybdenum wire causes oxidation on the fixture surface, resulting in uneven discharge sparks, which in turn affects the cutting accuracy. Moreover, the larger the contact area with the guide roller bearing components, the larger the friction surface, the faster the temperature rises, and the greater the impact on wire cutting.

[0007] Optionally, a first motor is fixed to the top of the control panel, and a bobbin is rotatably connected inside the wire frame. The output shaft of the first motor passes through the wire frame and is fixed to the bobbin.

[0008] Optionally, a connecting rod is fixed to the surface of the first storage rack away from the scraper, and a second storage rack is fixed to the bottom end of the connecting rod. The second storage rack is hollow and has an arc-shaped bottom.

[0009] Optionally, the bottom of both ends of the first connector is provided with an embedded groove, an adjusting rod is slidably connected inside the embedded groove, a second connector is fixed to one end of the adjusting rod, a second guide roller is fixed to one side of the two second connectors opposite to each other, a spring is fixed inside the embedded groove, and one end of the spring is fixed to the adjusting rod.

[0010] Optionally, a recovery chamber is provided on the side of the auxiliary tooling away from the reserved adjustment chamber on the horizontal part, and a filter hole is provided on the top of the auxiliary tooling near the recovery chamber. An isolation frame is fixed on the top of the auxiliary tooling, and a second motor is fixed on one side of the auxiliary tooling located on the isolation frame. A fan blade roller is rotatably connected inside the isolation frame, and the output shaft of the second motor passes through the isolation frame and is fixedly connected to the fan blade roller.

[0011] Optionally, a third storage rack is fixed inside the recycling chamber, and a sealing door is hinged to one side of the horizontal part of the auxiliary tooling.

[0012] Optionally, a third connector is fixed to the bottom of the horizontal part of the auxiliary tooling near the recovery chamber, and a third guide roller is rotatably connected to the surfaces at both ends of the third connector.

[0013] A method for inspecting multi-wire cut workpieces using a laser inspection fixture, comprising the following steps: A1: The molybdenum wire is passed through the first guide roller, the nylon roller, the third guide roller, and other guide rollers on the operating table. Then, the tension of the molybdenum wire is detected by laser using a laser sensor. The sensor controls the cylinder to drive the nylon roller to adjust the tension. During cutting, the molybdenum wire is water-cooled and dissipates heat through the first guide roller. A2: After the molybdenum wire passes through the water-cooled heat dissipation of the first guide roller, the impurities on its surface soften. When it passes through the nylon roller, the nylon roller scrapes off the impurities from the molybdenum wire, and the scraper cleans the nylon roller. At the same time, the scraper generates static electricity on the nylon roller, which further adsorbs the impurities on the surface of the molybdenum wire. A3: When the molybdenum wire passes through the third guide roller, the fan blade roller is activated by the second motor to evacuate the inside of the recovery chamber, thereby drawing the air around the third guide roller into the recovery chamber. This accelerates the airflow speed on the surface of the third guide roller and around the molybdenum wire, achieving the effects of adsorbing impurities on the surface of the molybdenum wire and air cooling.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The laser inspection fixture and method for multi-wire cutting workpieces, through the setting of a first guide roller, a nylon roller and a third guide roller, uses a laser sensor to detect the tension of the molybdenum wire, and starts the cylinder to drive the nylon roller to move the molybdenum wire up and down for adjustment, thereby completing the tension adjustment of the molybdenum wire. During cutting, the first connector transfers cooling water to the first guide roller, which cools the molybdenum wire. After the first guide roller cools the molybdenum wire, it is then scraped by the nylon roller, which improves the heat dissipation efficiency of the molybdenum wire and ensures the accuracy of the subsequent molybdenum wire cutting.

[0015] 2. The laser inspection fixture and method for multi-wire cut workpieces, when the cooling water is transferred to the molybdenum wire through the first guide roller, the excess cooling water is transferred to the spring, so that when the subsequent molybdenum wire passes through the first guide roller, the spring and the first guide roller simultaneously perform a water immersion operation on the molybdenum wire, which further improves the efficiency of water cooling heat dissipation, and provides relative humidity for the electrostatic field generated by the friction between the subsequent nylon roller and the scraper, ensuring the stability of the electrostatic field and improving the efficiency of the nylon roller in electrostatically adsorbing impurities on the surface of the molybdenum wire.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1:

[0020] Please see Figure 1-8 A laser inspection fixture for multi-wire cutting workpieces includes an operating table 1 and a wire frame 2. The wire frame 2 is fixed to the top of the operating table 1. The fixture is characterized in that: a displacement system 11 is fixed to one side of the top of the operating table 1, an auxiliary fixture 3 is fixed to the top of the wire frame 2, a reserved adjustment cavity 31 is provided in the middle of the horizontal part of the auxiliary fixture 3, a water storage cavity 32 is provided on the side of the horizontal part of the auxiliary fixture 3 near the displacement system 11, a water inlet 321 is provided at the top of the water storage cavity 32, a first connector 33 is fixed to the bottom of the water storage cavity 32 and the first connector 33 communicates with the water storage cavity 32, a first guide roller 34 is rotatably connected to the bottom of both ends of the first connector 33, the first guide roller 34 is rotatably sealed to the bottom end of the first connector 33, a cylinder 35 is fixed to the surface of the reserved adjustment cavity 31, a mounting bracket 36 is fixed to the output shaft of the cylinder 35, and a laser sensor 37 is fixed to the surface of the reserved adjustment cavity 31 on one side of the cylinder 35. The bottom of the mounting frame 36 is fixed with a first storage frame 38. Nylon rollers 39 are rotatably connected to both ends of the first storage frame 38. Scraper plates 391 are fixed to the surfaces of both ends of the first storage frame 38. The scraper plates 391 are slidably connected to the first storage frame 38. A lifting system 12 is fixed to the top of the operating table 1 near the wire frame 2. A molybdenum wire disc 13 is fixed to the surface of the lifting system 12. A first motor 21 is fixed to the top of the operating table 1. A spool 22 is rotatably connected inside the wire frame 2. The output shaft of the first motor 21 passes through the wire frame 2 and is fixed to the spool 22. A connecting rod 4 is fixed to the surface of the first storage frame 38 away from the scraper plate 391. A second storage frame 41 is fixed to the bottom end of the connecting rod 4. The second storage frame 41 is hollow and the bottom of the second storage frame 41 is arc-shaped. Specifically, firstly, the molybdenum wire reel 13 is installed on the lifting system 12. Then, the molybdenum wire is taken out from the molybdenum wire reel 13 and pulled through the first guide roller 34, the nylon roller 39, the spool 22 and other guide wheels on the operating table 1 in sequence. The bottom of the first guide roller 34 contacts and drives the molybdenum wire, and the top of the nylon roller 39 contacts and drives the molybdenum wire. The laser sensor 37 can then be activated by the controller to perform laser detection on the molybdenum wires at the top of the two nylon rollers 39. The detection result is transmitted to the cylinder 35 via the laser sensor 37, causing the cylinder 35 to start. The cylinder 35 drives the mounting frame 36 to move up and down within the reserved adjustment cavity 31. This causes the mounting frame 36 to drive the first storage frame 38 and the nylon rollers 39 to move up and down synchronously, thereby adjusting the tension of the molybdenum wires through the nylon rollers 39. This is the step of automatically adjusting the tension in the prior art through the cooperation of the laser sensor 37, the cylinder 35, and the nylon rollers 39. This invention will not elaborate further. Furthermore, in actual operation, cooling water is first injected into the water storage chamber 32 through the water inlet 321. Since the water storage chamber 32 is connected to the first connecting member 33, some cooling water enters the interior of the first connecting member 33. When wire cutting is being performed and the molybdenum wire is in a high-speed transmission state, when the molybdenum wire passes through the first guide roller 34, the molybdenum wire drives the first guide roller 34 to rotate. During the rotation of the first guide roller 34, part of its surface contacts the inner wall of the first connecting member 33 in sequence. That is, the cooling water in the first connecting member 33 is guided to the molybdenum wire by the rotation of the first guide roller 34, thereby allowing the molybdenum wire to be cooled by water. Meanwhile, after being soaked in water, the surface of the molybdenum wire is wet, and the impurities on the surface of the molybdenum wire, such as metal shavings or abrasive particles, are softened and loosened. After being soaked in water, the molybdenum wire passes through the nylon roller 39. When the molybdenum wire passes through the nylon roller 39 and the scraper plate 391 on the side close to the molybdenum wire disc 13, the molybdenum wire drives the nylon roller 39 to rotate. During the transmission process, the nylon roller 39 scrapes off the softened impurities on the surface of the molybdenum wire. At the same time, during the rotation of the nylon roller 39, the impurities adhering to the nylon roller 39 are scraped off again by the scraper plate 391, so that the impurities on the surface of the molybdenum wire are scraped off into the interior of the first collection rack 38, thereby achieving the purpose of collecting the impurities on the surface of the molybdenum wire. This reduces the adhesion of impurities to the surface of the molybdenum wire, reduces the alteration of the wire's conductivity by these impurities, improves the uniformity of discharge, and thus improves the precision of wire cutting. At the same time, it also avoids the probability of impurities following the movement of the molybdenum wire and ultimately adhering to the surface of the spool 22, improving the cleanliness of the spool 22 surface and preventing the molybdenum wire from shifting due to the adhesion of impurities, thereby improving the cutting precision of the molybdenum wire.

[0021] It should be noted that all the devices in this invention are controlled by a control system. The scraper 391 is made of PTFE material, and there are two nylon rollers 39. While adjusting the tension, they also adsorb impurities after the molybdenum wire surface softens, reducing the degree of impurity adhesion on the molybdenum wire surface and reducing the problem of reduced heat dissipation efficiency of the molybdenum wire due to impurity adhesion, thus indirectly improving the heat dissipation efficiency of the molybdenum wire. When the online shaft 22 rotates counterclockwise, the second guide roller 53, nylon roller 39, third guide roller 71 and other guide wheels also rotate counterclockwise, while the first guide roller 34 rotates clockwise. During this process, when the nylon roller 39, which is away from the lifting system 12, rotates, static electricity is generated between the scraper plate 391 and the nylon roller 39 through friction, so that an electric field is formed in the local area of ​​friction between the nylon roller 39 and the scraper plate 391. As the molybdenum wire-driven nylon roller 39 rotates, the electrostatic field of the nylon roller 39 comes into contact with the molybdenum wire, and metal debris on the surface of the molybdenum wire is adsorbed during the contact process. As the metal debris adsorbed by the nylon roller 39 gradually moves away from the scraper plate 391, the electrostatic field gradually disappears and loses its adsorption of metal debris. At this time, the metal debris can fall into the interior of the second collection rack 41 and be collected. Furthermore, based on the water cooling of the molybdenum wire by the cooling water inside the first connector 33, the air humidity below the auxiliary tooling 3 is greater than the humidity outside the auxiliary tooling 3. That is, the humidity around the water-immersed molybdenum wire is greater than that of the un-immersed molybdenum wire. The molybdenum wire improves the humidity between the nylon roller 39 and the scraper 391, making the electrostatic field generated by the friction between the scraper 391 and the nylon roller 39 more stable. This makes the electrostatic adsorption of metal debris on the surface of the molybdenum wire by the nylon roller 39, which is far away from the lifting system 12, more stable, further improving the efficiency of electrostatic dust removal, and thus improving the efficiency of subsequent wire cutting.

[0022] Example 2:

[0023] The bottom of both ends of the first connector 33 is provided with an embedded groove 5. An adjusting rod 51 is slidably connected inside the embedded groove 5. A second connector 52 is fixed to one end of the adjusting rod 51. A second guide roller 53 is fixed to one side of the two second connectors 52 opposite to each other. A spring 54 is fixed inside the embedded groove 5. One end of the spring 54 is fixed to the adjusting rod 51. Specifically, based on Embodiment 1, during the installation of the molybdenum wire, the second guide roller 53 is pulled to increase the distance between the second guide roller 53 and the first guide roller 34, thereby facilitating the passage of the molybdenum wire through the first guide roller 34 and the second guide roller 53. This allows the distance between the first guide roller 34 and the second guide roller 53 to be adapted to the current diameter and thickness of the molybdenum wire, ensuring that the first guide roller 34 and the second guide roller 53 can fully contact the molybdenum wire and that the molybdenum wire can simultaneously drive the first guide roller 34 and the second guide roller 53 to rotate. During wire cutting, when the molybdenum wire passes the bottom of the first guide roller 34 and drives the first guide roller 34 to rotate, the molybdenum wire simultaneously passes the second guide roller 53, causing the second guide roller 53 to rotate synchronously. That is, the first guide roller 34 synchronously drives the first guide roller 34 and the second guide roller 53 to rotate. During the rotation of the first guide roller 34, the cooling water in the first connecting member 33 is guided to the molybdenum wire, and the excess cooling water is transferred to the second guide roller 53 through the molybdenum wire, thereby allowing the second guide roller 53 to also be immersed in water. During the continuous transmission of the molybdenum wire, when the subsequent molybdenum wire drives the first guide roller 34 and the second guide roller 53, the second guide roller 53 and the first guide roller 34, which are immersed in water, simultaneously perform water cooling operation on the molybdenum wire, thereby improving the overall contact of the molybdenum wire with the cooling water and thus improving the heat dissipation effect of the molybdenum wire.

[0024] It should be noted that since the spring 54 is fixed to the adjusting rod 51 and the inner groove 5 respectively, that is, the second guide roller 53 has a certain rebound force, when the debris on the surface of the molybdenum wire passes through the spring 54 and the first guide roller 34, the second guide roller 53 can squeeze the debris on the surface of the molybdenum wire while ensuring that the molybdenum wire passes stably through the first guide roller 34, which further loosens the debris on the surface of the molybdenum wire and improves the efficiency of the nylon roller 39 in scraping the debris on the surface of the molybdenum wire.

[0025] Example 3:

[0026] A recovery chamber 6 is provided on the side of the horizontal part of the auxiliary tooling 3 away from the reserved adjustment chamber 31. A filter hole 61 is provided on the top side of the auxiliary tooling 3 near the recovery chamber 6. An isolation frame 62 is fixed on the top of the auxiliary tooling 3. A second motor 63 is fixed on one side of the auxiliary tooling 3 located on the isolation frame 62. A fan blade roller 64 is rotatably connected inside the isolation frame 62. The output shaft of the second motor 63 passes through the isolation frame 62 and is fixedly connected to the fan blade roller 64. A third storage frame 65 is fixed inside the recovery chamber 6. A sealing door 66 is hinged on one side of the horizontal part of the auxiliary tooling 3. A third connecting piece 7 is fixed at the bottom of the horizontal part of the auxiliary tooling 3 near the recovery chamber 6. A third guide roller 71 is rotatably connected to the surfaces of both ends of the third connecting piece 7. Specifically, based on Embodiment 1 and Embodiment 2, during installation, after the molybdenum wire passes through the nylon roller 39, it is passed through the third connector 7, so that the top of the third guide roller 71 contacts the molybdenum wire. Then, the molybdenum wire is wound around the surface of the spool 22. Thus, when the tension is adjusted, the third guide roller 71 and the first guide roller 34 serve as support members on both sides. After the laser sensor 37 performs laser detection on the molybdenum wire, the sensor controls the cylinder 35 to drive the nylon roller 39 to adjust the height, thereby achieving the purpose of automatically controlling the tension. Once the tension is adjusted, wire cutting can be performed. During the cutting process, when the spool 22 rotates counterclockwise, the molybdenum wire is cooled by the cooling water in the first connector 33 and then passes through the nylon roller 39. The electrostatic field generated by the friction between the nylon roller 39 and the scraper 391 removes impurities from the surface of the molybdenum wire and simultaneously adsorbs metallic impurities from the surface of the molybdenum wire. When the molybdenum wire passes the third guide roller 71, the controller starts the second motor 63, which drives the fan roller 64 to rotate, thereby performing an air extraction operation inside the recovery chamber 6. This allows the third connector 7 to act as a pipe structure, drawing air from around the third guide roller 71 into the third connector 7 and the recovery chamber 6. In other words, the fan roller 64 performs an air extraction operation on the third guide roller 71 and the molybdenum wire on its surface. Due to the cooperation of the laser sensor 37, the cylinder 35, and the nylon roller 39, the tension of the molybdenum wire is automatically adjusted, ensuring that the molybdenum wire always adheres to the surface of the third guide roller 71. The air around the molybdenum wire on the surface of the third guide roller 71, as well as any remaining debris on the surface of the molybdenum wire, are drawn into the recovery chamber 6 along with the airflow and are eventually collected inside the third storage rack 65. Thus, the fan blade roller 64 provides air cooling for the molybdenum wire and simultaneously draws away and adsorbs any remaining debris from the surface of the molybdenum wire into the interior of the third storage rack 65, further improving the efficiency of dust removal from the molybdenum wire. After cutting is completed, the sealing door 66 can be opened and the third storage rack 65 can be cleaned.

[0027] Example 4:

[0028] This invention also provides a method for inspecting multi-wire cut workpieces using a laser inspection fixture, comprising the following steps: A1: The molybdenum wire is passed through the first guide roller 34, the nylon roller 39, the third guide roller 71, and other guide rollers of the operating table 1. Then, the tension of the molybdenum wire is detected by laser sensor 37. The sensor controls the cylinder 35 to drive the nylon roller 39 to adjust the tension. During cutting, the molybdenum wire is water-cooled and dissipates heat through the first guide roller 34. A2: After the molybdenum wire passes through the water-cooled heat dissipation of the first guide roller 34, the impurities on its surface soften. When it passes through the nylon roller 39, the nylon roller 39 scrapes off the impurities of the molybdenum wire, and the scraper plate 391 cleans the nylon roller 39. At the same time, the scraper plate 391 generates frictional static electricity on the nylon roller 39, which further adsorbs the impurities on the surface of the molybdenum wire. A3: When the molybdenum wire passes through the third guide roller 71, the second motor 63 starts the fan roller 64 to draw air into the inside of the recovery chamber 6, thereby drawing the air around the third guide roller 71 into the inside of the recovery chamber 6, thus accelerating the airflow speed on the surface of the third guide roller 71 and around the molybdenum wire, achieving the effects of adsorbing impurities on the surface of the molybdenum wire and air cooling.

A3: When the molybdenum wire passes through the third guide roller (71), the fan roller (64) is started by the second motor (63) to pump air into the inside of the recovery chamber (6), thereby drawing the air around the third guide roller (71) into the inside of the recovery chamber (6), thereby accelerating the air flow speed on the surface of the third guide roller (71) and around the molybdenum wire, achieving the effect of adsorbing impurities on the surface of the molybdenum wire and air cooling.
