Description

Technical Field

[0001] This invention relates to the field of experimental equipment technology, and in particular to an experimental apparatus and method for a resin-metal composite dicing blade. Background Technology

[0002] Resin-metal composite dicing blades are cutting tools used in high-precision cutting processes, primarily for dicing brittle materials such as semiconductor wafers, ceramics, glass, and magnetic materials. Their structure typically consists of a metal matrix, diamond abrasive, and resin binder, combining the toughness of resin with the strength of metal, resulting in high cutting accuracy and a long service life.

[0003] The prior art publication CN112326545B provides a composite salt spray test chamber. This chamber uses a rotor within a housing to rotate, with a shaft tube for introducing liquid (such as a salt solution or other liquid). A particle chamber holds particulate matter (such as salt, sand, or other particulate mixtures). When the particle or liquid outlet rotates to the emission window, under centrifugal force, particulate matter and droplets are pulsed, intermittently, and alternately emitted from the emission window to the test subject, simulating intermittent salt particle impact and salt liquid shock conditions. Furthermore, the composite salt spray test chamber of this invention has a simple structure, requires no high-pressure gas, and avoids gas interference in the test. The composite salt spray test chamber of this invention can be equipped with a water valve to control the flow of liquid into the outlet, and can selectively spray salt spray.

[0004] In existing technologies, when conducting corrosion resistance tests on disc-shaped resin-metal composite dicing blades with serrated edges, it is not convenient to position the blades correctly, causing them to easily slide or tilt in the test chamber. Random placement can lead to some areas being directly exposed to the salt spray zone for extended periods, while other areas are avoided, affecting the uniformity of corrosion.

[0005] In summary, the existing technology lacks a suitable positioning and placement technology for disc-shaped resin-metal composite dicing blades with serrated edges. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a resin-metal composite dicing blade experimental device and method.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a resin-metal composite dicing blade experimental device, comprising a salt spray test chamber, a guide rail frame fixedly connected inside the salt spray test chamber, two movable seats slidably connected on the guide rail frame, a rotating seat rotatably connected on the movable seats, a plurality of transmission mechanisms rotatably connected through the rotating seats, an adjusting seat above the transmission mechanisms, a positioning mechanism rotatably connected on the adjusting seat, and a pushing mechanism rotatably connected on the positioning mechanism.

[0008] Preferably, the guide rail frame is T-shaped, with guide grooves provided on the guide rail frame and insertion holes provided on the inner wall of each end of the guide rail frame.

[0009] Preferably, a T-shaped column is fixedly connected to the bottom of the movable seat. The outer wall of the bottom of the T-shaped column is slidably fitted with the inner wall of the guide groove. Multiple balls are embedded on the lower surface of the T-shaped column. A plug rod is slidably fitted through the T-shaped column. The bottom end of the plug rod is movably inserted into the insertion hole. A toothed ring is fixedly connected to the movable seat. A tension spring is fixedly connected to the top of the plug rod. The other end of the tension spring is fixedly connected to the inner wall of the T-shaped column. A handle is fixedly connected to the outer end of the plug rod.

[0010] Preferably, the bottom end of the rotating seat extends to the inner wall of the movable seat and is fixedly connected to a motor, the motor being fixedly connected to the inner wall of the movable seat.

[0011] Preferably, the transmission mechanism includes a universal joint, with both ends of the universal joint rotatably connected to the rotating seat. One end of the universal joint extends through the upper surface of the rotating seat to the lower side and is fixedly connected to a drive wheel. The drive wheel meshes with a gear ring for transmission. The other end of the universal joint is fixedly connected to a driven wheel.

[0012] Preferably, one side of the adjusting seat has a ring-shaped structure with multiple sliding grooves, one end of the adjusting seat is rotatably connected to the rotating seat, and an annular rack is fixedly connected to the outer wall of the adjusting seat, the annular rack meshing with the driven wheel for transmission.

[0013] Preferably, the positioning mechanism includes a second motor, which is fixedly connected to the inner wall of the adjusting seat. A turntable is fixedly connected to the output end of the second motor. The turntable has multiple adjusting grooves in a ring structure. A guide rod is slidably fitted into each adjusting groove. A positioning rod is fixedly connected to one end of the guide rod. One end of the positioning rod is slidably fitted into the inner wall of the groove. A baffle is fixedly connected to the other end of the positioning rod. A limit groove is formed on one of the positioning rods.

[0014] Preferably, the pushing mechanism includes a pushing block, which is slidably coupled to a positioning rod with a limiting groove. A spring is fixedly connected to one side of the pushing block, and the other end of the spring is fixedly connected to the positioning rod. A pushing rod assembly is rotatably connected to the pushing block, and the other end of the pushing rod assembly is rotatably connected to the positioning rod. A gear is fixedly connected to one end of the pushing rod assembly connected to the positioning rod. A rack is meshed with one side of the gear and is slidably coupled to the positioning rod. A contact plate is fixedly connected to one end of the rack and is in movable contact with the inner wall of the chute.

[0015] A method for using a resin-metal composite scribing blade experimental device includes the following steps: S1. When it is necessary to conduct a corrosion resistance test on a disc-shaped resin-metal composite dicing blade with serrated edges, first place multiple dicing blades on the positioning mechanism on the rotating seat. S2. Then, the positioning mechanism is used to clamp and fix the center hole of the dicing blade. At this time, under the action of the pushing mechanism, the dicing blade can be automatically pushed to the side of the positioning mechanism to achieve double positioning of the dicing blade. S3. Then, the movable seat is pushed into the salt spray test chamber through the guide rail frame to conduct the salt spray corrosion resistance test. S4. During the salt spray corrosion resistance test, the rotating seat drives multiple dicing blades to rotate, and the transmission mechanism drives the adjusting seat to rotate, so that the dicing blades on the positioning mechanism follow the rotation, thereby ensuring that the salt spray can contact the target area evenly.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a positioning mechanism and a pushing mechanism in the salt spray test chamber, after the dicing blade is placed on the positioning rod with the positioning mechanism, the turntable is driven by motor 2 to rotate, which causes the turntable to move multiple positioning rods outward, thereby positioning the dicing blade. At this time, the pushing mechanism is unrestricted. Under the action of the spring, it will drive the push block to automatically push the dicing blade against the stop plate for positioning, avoiding skewness and overturning, and ensuring the consistency of the initial state of the test. By accurately controlling the position of the dicing blade, consistency and comparability are ensured. At the same time, the efficiency of test preparation is improved through automatic clamping, rapid positioning and batch processing. 2. By setting a rotating base, multiple disc-shaped resin-metal composite dicing blades with serrated edges can be rotated. At the same time, under the action of the transmission mechanism, the disc-shaped resin-metal composite dicing blades with serrated edges are rotated. This allows each dicing blade to continuously change its spatial position within the test chamber when the salt spray test chamber is used to test the corrosion resistance of the disc-shaped resin-metal composite dicing blades with serrated edges. This avoids the differences in salt spray deposition caused by fixed positions, and ensures that each surface and each serrated edge of the blade is periodically exposed to the salt spray, completely eliminating the phenomenon of uneven corrosion on one side or in a localized area. 3. By setting up a guide rail frame, the two moving seats can be switched. While the dicing blade on one moving seat is undergoing corrosion resistance testing inside the salt spray test chamber, the other moving seat is located outside and the dicing blade can be disassembled and installed. This improves the efficiency of corrosion resistance testing of disc-shaped resin-metal composite dicing blades with serrated edges in the salt spray test chamber. Traditional salt spray tests require unpacking, cooling, and cleaning after the test before loading the next batch of samples, resulting in long downtime. With this solution, while one station is testing, the other station can safely disassemble the old blade and install the new blade from the outside. The switch can be made quickly as soon as the test ends, with almost no waiting time, thus increasing the daily testing throughput. Attached Figure Description

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figures 1-8 The apparatus and method for testing resin-metal composite dicing blades shown include a salt spray test chamber 1. A guide rail frame 2 is fixedly connected inside the salt spray test chamber 1. Two movable seats 3 are slidably connected on the guide rail frame 2. A rotating seat 4 is rotatably connected to the movable seat 3. Multiple transmission mechanisms 5 are rotatably connected through the rotating seat 4. An adjustment seat 6 is set above the transmission mechanism 5. A positioning mechanism 7 is rotatably connected to the adjustment seat 6. A pushing mechanism 8 is rotatably connected to the positioning mechanism 7. The intelligent sensor system integrated in the salt spray test chamber (1) includes a salt spray concentration sensor, a temperature and humidity sensor, a corrosion potential sensor, and a vibration sensor. The salt spray concentration sensor is installed in the middle of the inner wall of the salt spray test chamber (1) to monitor the salt spray concentration in the chamber in real time with an accuracy of ±0.1%. The data is dynamically adjusted by the control system to adjust the spray volume of the salt spray generator to ensure that the salt spray concentration is stable at the preset value, adapting to the corrosion environment requirements of different new material dicing blades.

[0021] like Figure 3 As shown, the guide rail frame 2 is T-shaped, with guide grooves 201 on the guide rail frame 2 and insertion holes 202 on the inner walls of each end of the guide rail frame 2.

[0022] The T-shaped guide rail 2 can provide stable guidance for two movable seats 3 at the same time, ensuring that the movable seats 3 slide along a fixed trajectory and avoid deviation; the cross-sectional dimensions of the guide groove 201 are precisely matched with the T-shaped column 301 of the movable seat 3 to ensure smooth sliding.

[0023] like Figure 4As shown, a T-shaped post 301 is fixedly connected to the bottom of the movable base 3. The outer wall of the bottom of the T-shaped post 301 is slidably fitted with the inner wall of the guide groove 201. Multiple balls 302 are embedded on the lower surface of the T-shaped post 301. A plug rod 303 is slidably fitted through the T-shaped post 301. The bottom end of the plug rod 303 is movably inserted into the plug hole 202. A toothed ring 304 is fixedly connected to the movable base 3. A tension spring 305 is fixedly connected to the top of the plug rod 303. The other end of the tension spring 305 is fixedly connected to the inner wall of the T-shaped post 301. A handle 306 is fixedly connected to the outer end of the plug rod 303.

[0024] The ball bearing 302 is made of high-strength bearing steel, which converts sliding friction into rolling friction, greatly reducing the resistance when the movable seat 3 slides, and reducing component wear. The tension spring 305 is always in a stretched state, which can automatically pull the insertion rod 303 downward to insert into the insertion hole 202, realizing the automatic locking of the movable seat 3 and preventing the movable seat 3 from sliding accidentally during the experiment. The handle 306 is covered with anti-slip rubber material, which makes it easy for the operator to manually pull the insertion rod 303 to unlock the movable seat 3.

[0025] like Figure 5 As shown, the bottom end of the rotating seat 4 extends to the inner wall of the movable seat 3 and is fixedly connected to a motor 401. The motor 401 is fixedly connected to the inner wall of the movable seat 3.

[0026] Motor 401 is a servo motor with adjustable speed and smooth start and stop. Its output shaft is rigidly connected to the rotating seat 4 through a coupling, which can accurately drive the rotating seat 4 to drive multiple dicing blades to rotate.

[0027] like Figure 5 As shown, the transmission mechanism 5 includes a universal joint 501. Both ends of the universal joint 501 are rotatably connected to the rotating base 4. One end of the universal joint 501 extends through the upper surface of the rotating base 4 to the lower side and is fixedly connected to a driving wheel 502. The driving wheel 502 meshes with a gear ring 304 for transmission. The other end of the universal joint 501 is fixedly connected to a driven wheel 503. The transmission mechanism 5 realizes the rotation of the dicing blade.

[0028] like Figure 6 As shown, the adjusting seat 6 has a ring structure with multiple sliding grooves 601 on one side. One end of the adjusting seat 6 is rotatably connected to the rotating seat 4. The outer wall of the adjusting seat 6 is fixedly connected with a ring rack 602, which meshes with the driven wheel 503 for transmission.

[0029] The ring rack 602 is welded to the adjusting seat 6 and meshes with the driven wheel 503. Driven by the driven wheel 503, it drives the dicing blade on the adjusting seat 6 and the positioning mechanism 7 to rotate, so that all parts of the dicing blade are evenly misted.

[0030] like Figure 7As shown, the positioning mechanism 7 includes a second motor 701, which is fixedly connected to the inner wall of the adjusting seat 6. A turntable 702 is fixedly connected to the output end of the second motor 701. The turntable 702 has a plurality of adjusting grooves 703 in a ring structure. A guide rod 704 is slidably fitted in the adjusting groove 703. A positioning rod 705 is fixedly connected to one end of the guide rod 704. One end of the positioning rod 705 is slidably fitted to the inner wall of the sliding groove 601. A baffle 706 is fixedly connected to the other end of the positioning rod 705. A limit groove 707 is formed on one of the positioning rods 705.

[0031] Motor 2 701 uses a miniature servo motor, which is small in size and has stable torque, and can accurately drive the rotation of turntable 702.

[0032] By setting a positioning mechanism 7 and a pushing mechanism 8 inside the salt spray test chamber 1, after the dicing blade is placed on the positioning rod 705 with the positioning mechanism 7, the turntable 702 is rotated by the motor 701, which causes the turntable 702 to move multiple positioning rods 705 outward, thereby positioning the dicing blade. At this time, the pushing mechanism 8 is unrestricted. Under the action of the spring 802, it will drive the push block 801 to automatically push the dicing blade against the baffle 706 for positioning, avoiding skewness and overturning, and ensuring the consistency of the initial state of the test. By accurately controlling the position of the dicing blade, consistency and comparability are ensured. At the same time, the efficiency of test preparation is improved by automatic clamping, rapid positioning, and batch processing.

[0033] like Figure 8 As shown, the pushing mechanism 8 includes a push block 801, which is slidably engaged with a positioning rod 705 having a limit groove 707. A spring 802 is fixedly connected to one side of the push block 801, and the other end of the spring 802 is fixedly connected to the positioning rod 705. A push rod assembly 803 is rotatably connected to the push block 801, and the other end of the push rod assembly 803 is rotatably connected to the positioning rod 705. A gear 804 is fixedly connected to one end of the push rod assembly 803 connected to the positioning rod 705. A rack 805 is meshed with one side of the gear 804, and the rack 805 is slidably engaged with the positioning rod 705. A contact plate 806 is fixedly connected to one end of the rack 805, and the contact plate 806 is in movable contact with the inner wall of the slide groove 601. The push block 801 is made of wear-resistant plastic material with a smooth surface, which will not damage its surface when in contact with the dicing blade.

[0034] A method for using a resin-metal composite scribing blade experimental device includes the following steps: S1. When it is necessary to conduct a corrosion resistance test on a disc-shaped resin-metal composite dicing blade with serrated edges, first place multiple dicing blades on the positioning mechanism 7 on the rotating seat 4. S2. Then, the positioning mechanism 7 is used to clamp and fix the center hole of the dicing knife. At this time, under the action of the pushing mechanism 8, the dicing knife can be automatically pushed to one side of the positioning mechanism 7 to achieve double positioning of the dicing knife. S3. Then, the movable seat 3 is pushed into the salt spray test chamber 1 through the guide rail frame 2 to conduct the salt spray corrosion resistance test. S4. During the salt spray corrosion resistance test, the rotating seat 4 drives multiple dicing blades to rotate, and the transmission mechanism 5 drives the adjusting seat 6 to rotate, so that the dicing blades on the positioning mechanism 7 follow the rotation, thereby ensuring that the salt spray can contact the target area evenly.

[0035] Working principle: When it is necessary to conduct corrosion resistance tests on disc-shaped resin-metal composite dicing blades with serrated edges, first place multiple dicing blades on the positioning mechanism 7 on the rotating seat 4. In this step, it is necessary to first ensure that the moving seat 3 is in the unlocked state outside the salt spray test chamber 1. The operator aligns the center hole of the dicing blade with the multiple positioning rods 705 of the positioning mechanism 7 and gently places it on the positioning rods 705 to ensure that the dicing blade is placed stably and to avoid collision damage to the serrated edge.

[0036] Then, start motor 701. Motor 701 drives turntable 702 to rotate. Turntable 702 drives guide rod 704 to move through adjustment groove 703, so that multiple positioning rods 705 extend outward synchronously along slide groove 601 until the outer wall of positioning rod 705 is tightly attached to the inner wall of the center hole of the dicing knife, completing the internal clamping and fixing. During this process, contact plate 806 separates from the inner wall of slide groove 601, spring 802 pushes push block 801 to move. Push block 801 adjusts its position through the linkage of push rod group 803, gear 804, and rack 805, and finally pushes the dicing knife towards the baffle 706 and tightly attaches it, achieving double positioning and ensuring that the dicing knife is not skewed or loose.

[0037] Then, the movable seat 3 is pushed into the salt spray test chamber 1 via the guide rail 2 to conduct the salt spray corrosion resistance test; the operator releases the handle 306, the tension spring 305 pulls the insertion rod 303 downward to insert it into the insertion hole 202 of the guide rail 2 to lock the movable seat 3; the door of the salt spray test chamber 1 is closed, and parameters such as salt spray concentration, temperature, and test duration are set according to the experimental requirements. The salt spray test system is then started to begin the corrosion resistance test.

[0038] During the salt spray corrosion resistance test, motor 401 is started, which drives rotating seat 4 to rotate. Rotating seat 4 drives multiple dicing blades to rotate along a circular trajectory. At the same time, rotating seat 4 drives the drive wheel 502 of transmission mechanism 5 to rotate around gear ring 304. The drive wheel 502 meshes with the fixed gear ring 304 and rotates on its own axis. Through universal joint 501, it drives the driven wheel 503 to rotate. The driven wheel 503 meshes with the ring rack 602 of adjusting seat 6, driving adjusting seat 6 to rotate, which in turn drives the dicing blades on positioning mechanism 7 to rotate on their own axis. Under the combined motion of rotation and rotation, each surface and each serrated edge of the dicing blade can be periodically exposed to salt spray, ensuring uniform corrosion.

[0039] After the experiment, open the door of the salt spray test chamber 1, pull the handle 306 to disengage the insertion rod 303 from the insertion hole 202, and pull the movable seat 3 out along the guide rail 2 to the outside of the test chamber; start the motor 701 to reverse, drive the positioning rod 705 to retract, release the clamping of the dicing blade, and remove the dicing blade for subsequent corrosion degree testing; at the same time, push another movable seat 3 with the dicing blade clamped and positioned into the salt spray test chamber 1, repeat the steps, and start the next batch of experiments.
