Description

Technical Field

[0001] This invention relates to the field of suction cup tooling technology, and more particularly to a suction cup tooling for turning hard disk substrates. Background Technology

[0002] The hard drive substrate is one of the key components of a hard drive. It is the basic medium for storing data and its main function is to provide a smooth, flat surface for the magnetic recording layer. It is usually a thin, circular sheet, and its material is generally glass or aluminum alloy. Glass substrates have high hardness, smoothness, and stability, allowing the read / write head to fly stably at very close range, ensuring the accuracy of data reading and writing. Aluminum alloy substrates are less expensive and also have good mechanical properties. A magnetic material is coated on the surface of the hard drive substrate through a special process to form a magnetic recording layer, which is used to store binary data. This data is distributed on the substrate in the form of tracks and sectors. The read / write head moves above the high-speed rotating substrate, writing and reading data by changing the magnetic state of the magnetic recording layer.

[0003] In the prior art, before turning, the hard disk substrate is placed directly on the chuck. Due to the friction between the chuck and the substrate, it is not easy to directly position the substrate, which affects subsequent processing. Furthermore, since the substrate itself is relatively light, there may be gaps between the substrate and the chuck, which affects the adsorption effect and causes the substrate to shift. Summary of the Invention

[0004] This invention discloses a hard disk substrate turning chuck fixture, which aims to solve the technical problems in the prior art where the friction between the chuck and the substrate makes positioning difficult, and the gap between the substrate and the chuck may affect the adsorption effect, thus causing the substrate to shift.

[0005] This invention proposes a hard disk substrate turning chuck fixture, comprising an installation body, a worktable and a fixed plate frame fixedly connected to the inner wall of the installation body, and a positioning operation module disposed inside the installation body. The same chuck module is disposed on the fixed plate frame and the worktable. The positioning operation module includes a rotary table, and an annular groove is formed on the bottom inner wall of the installation body. The rotary table is movably connected to the annular groove. Multiple circular holes are formed at equal intervals around the circumference of the rotary table. Fixed shafts are fixedly connected to the multiple circular holes. Irregular connecting rods are movably connected to the outer walls of the multiple fixed shafts. The chuck module includes an air chamber, and a sliding groove is formed on the worktable. The air chamber slides within the sliding groove. Multiple circular holes are formed at equal intervals on the air chamber. A chuck component is fixedly connected to each of the multiple circular holes.

[0006] In a preferred embodiment, each of the multiple irregularly shaped connecting rods is provided with a circular hole three, and a sliding table is movably connected in each of the multiple circular holes three. Furthermore, multiple sliding slot holes two are provided at equal intervals around the circumference of the worktable, and the multiple sliding tables slide in the corresponding sliding slot holes two.

[0007] In a preferred embodiment, each of the multiple sliding tables is fixedly connected to a mounting bracket, and each mounting bracket has a mounting hole 1 and a mounting hole 2. Each mounting hole 1 is fixedly connected to a stop block, and each mounting hole 2 is fixedly connected to an electric push rod. Each drive end of the electric push rod is fixedly connected to a pressing plate.

[0008] In a preferred embodiment, a toothed ring is fixedly connected to the outer wall of the rotary table, and a hydraulic rod is fixedly connected to the bottom inner wall of the mounting body. A toothed rod is fixedly connected to the drive end of the hydraulic rod, and the toothed rod and the toothed ring mesh with each other.

[0009] In a preferred embodiment, a connecting compartment is fixedly connected to the bottom of the workbench, and multiple corresponding circular holes are equally spaced on both the workbench and the connecting compartment. A piston cylinder is fixedly connected to each of the multiple circular holes, and piston plates are slidably connected to the inner walls of the multiple piston cylinders. A support rod is fixedly connected to the top of each of the multiple piston plates, and a universal ball bearing is fixedly connected to the top of each of the multiple support rods.

[0010] In a preferred embodiment, an air pump is fixedly connected to the top of the fixed plate frame, and a connecting pipe is fixedly connected to the output end of the air pump. The end of the connecting pipe away from the air pump is fixedly connected to the connecting chamber.

[0011] By incorporating a positioning module, before the turning process begins, an air pump sends air through a connecting pipe into the connecting chamber, forcing the piston plate to slide inside the piston cylinder. This pushes the support rod and universal ball bearings upward, placing the hard disk substrate onto the universal ball bearings. Then, the hydraulic rod is activated to push and pull the gear rod, rotating the rotary table through gear ring engagement. This forces the irregularly shaped connecting rod to rotate outside the fixed shaft, pulling the sliding table and mounting bracket towards the center. The abutment block causes the substrate to slide onto the universal ball bearings until the substrate reaches the center position, completing the positioning. This prevents friction between the suction cup and the substrate from hindering direct positioning, facilitating subsequent processing. Simultaneously, an electric push rod pushes the pressing plate downward to press the substrate, eliminating gaps between the substrate and the suction cup, ensuring a tighter fit and preventing substrate displacement due to compromised adsorption.

[0012] In a preferred embodiment, a negative pressure pump is fixedly connected to the bottom of the air chamber, and an installation platform is fixedly connected to the top of the fixed plate frame. Multiple installation slots are equidistantly opened on the installation platform, and installation cylinders are fixedly connected in each of the multiple installation slots.

[0013] In a preferred embodiment, the inner walls of the plurality of mounting cylinders are slidably connected to sliding members, and each of the plurality of mounting cylinders is provided with a spring, one end of each spring being fixedly connected to the inner wall of the corresponding mounting cylinder, and the other end being fixedly connected to the corresponding sliding member.

[0014] In a preferred embodiment, the mounting platform has an annular groove II, in which a winding wheel is movably connected. A motor is fixedly connected to the top of the mounting platform, and a rotating frame is fixedly connected to the drive end of the motor. The outer wall of the rotating frame is fixedly connected to the inner wall of the winding wheel. Multiple winding ropes are surrounded around the outside of the winding wheel, and the ends of the multiple winding ropes away from the winding wheel are fixedly connected to corresponding sliding parts.

[0015] In a preferred embodiment, the bottom circumference of the air chamber is fixedly connected with multiple fasteners at equal intervals, and the side of the multiple sliding members away from the winding rope is fixedly connected with an arc-shaped connecting rod. The end of the multiple arc-shaped connecting rod away from the sliding member is provided with a circular hole five. A thin rod is fixedly connected inside the multiple circular holes five. A connecting plate is movably connected to the outer wall of the multiple thin rods. The end of the multiple connecting plates away from the arc-shaped connecting rod is movably connected to the corresponding fastener.

[0016] Equipped with a suction cup module, after the hard drive substrate is positioned, the motor rotates the rotating frame, causing the winding wheel to rotate and loosen the winding rope. The elasticity of the spring pushes the sliding component and the arc-shaped connecting rod, forcing the connecting plate to push the air chamber upward. When the suction cup contacts the substrate, a negative pressure pump creates a negative pressure state inside the air chamber, using the suction cup to fix the substrate. This allows the suction cup to retract into the device when not in use, preventing damage from collisions with other objects and improving applicability. When in use, the suction cup extends to better fit the substrate surface, ensuring effective adsorption.

[0017] As can be seen from the above, the hard disk substrate turning chuck fixture provided by the present invention can push the randomly placed hard disk substrate to the center position of the fixture for positioning through the positioning module before turning, which facilitates the subsequent turning process. At the same time, by pressing the hard disk substrate, the gap between the substrate and the chuck can be eliminated, making the substrate and the chuck fit more tightly, preventing the substrate from shifting due to the influence of the adsorption effect. Furthermore, the chuck can be retracted into the device when not in use to prevent damage caused by collisions with other objects. When in use, it extends to better fit the substrate surface, ensuring the beneficial effect of adsorption. Attached Figure Description

[0027] The hard disk substrate turning chuck tool disclosed in this invention is mainly used in scenarios where positioning is inconvenient due to friction between the chuck and the substrate, and gaps may exist between the substrate and the chuck, affecting the adsorption effect and causing substrate displacement.

An annular groove is opened on the bottom inner wall of the installation body 1. The rotary table 201 is movably connected to the annular groove. Multiple circular holes are equidistantly opened on the circumference of the rotary table 201. Fixed shafts 205 are fixedly connected to each of the multiple circular holes. Irregular connecting rods 206 are movably connected to the outer walls of the multiple fixed shafts 205. The suction cup module 3 includes an air chamber 301. A sliding groove is opened on the worktable 4. The air chamber 301 slides in the sliding groove. Multiple circular holes are equidistantly opened on the air chamber 301. Suction cup components 303 are fixedly connected to each of the multiple circular holes.

[0029] Reference Figure 1 , Figure 2 and Figure 3 Each of the multiple irregularly shaped connecting rods 206 has a circular hole 3, and each of the multiple circular holes 3 is movably connected to a sliding table 207. The worktable 4 has multiple sliding slot holes 2 equidistantly spaced around its circumference, and the multiple sliding tables 207 slide within the corresponding sliding slot holes 2.

[0030] Reference Figure 1 , Figure 3 and Figure 4 Each of the multiple sliding tables 207 has a mounting bracket 208 fixedly connected to its top. Each of the multiple mounting brackets 208 has a mounting hole 1 and a mounting hole 2. Each of the multiple mounting holes 1 has a stop block 210 fixedly connected to its top. Each of the multiple mounting holes 22 has an electric push rod 209 fixedly connected to its top. Each of the multiple electric push rods 209 has a pressing piece 211 fixedly connected to its driving end.

[0031] Reference Figure 1 , Figure 2 and Figure 3 A gear ring 202 is fixedly connected to the outer wall of the rotary table 201, and a hydraulic rod 203 is fixedly connected to the bottom inner wall of the mounting body 1. A gear rod 204 is fixedly connected to the drive end of the hydraulic rod 203, and the gear rod 204 meshes with the gear ring 202.

[0032] Reference Figure 1 , Figure 2 and Figure 5 The bottom of the workbench 4 is fixedly connected to a connecting chamber 212, and multiple corresponding circular holes 4 are equally spaced on both the workbench 4 and the connecting chamber 212. Piston cylinders 213 are fixedly connected inside each of the multiple circular holes 4. Piston plates 214 are slidably connected to the inner walls of the multiple piston cylinders 213. Support rods 215 are fixedly connected to the tops of the multiple piston plates 214. Universal ball bearings 216 are fixedly connected to the tops of the multiple support rods 215.

[0033] Reference Figure 1 , Figure 2 and Figure 5 An air pump 217 is fixedly connected to the top of the fixed plate frame 5, and a connecting pipe 218 is fixedly connected to the output end of the air pump 217. The end of the connecting pipe 218 away from the air pump 217 is fixedly connected to the connecting chamber 212.

[0034] In a specific application scenario, before the turning process begins, the air pump 217 is started to send air into the connecting chamber 212 through the connecting pipe 218, forcing the piston plate 214 to slide inside the piston cylinder 213, pushing the support rod 215 and the universal ball bearing 216 to rise, placing the hard disk substrate on the universal ball bearing 216. Then, the hydraulic rod 203 is started to push and pull the gear rod 204, which rotates the rotary table 201 through the engagement of the gear ring 202, forcing the irregular connecting rod 206 to rotate outside the fixed shaft 205, pulling the sliding table 212. 07 and mounting bracket 208 move towards the center, and the substrate slides on the universal ball bearing 216 through the abutment block 210 until the substrate reaches the center position to complete the positioning. This can prevent the friction between the suction cup and the substrate from making it difficult to position directly, and facilitate subsequent processing. At the same time, the electric push rod 209 is activated to push the pressing plate 211 to press the substrate downward, which can eliminate the gap between the substrate and the suction cup 303, so that the substrate and the suction cup 303 fit more tightly and prevent the substrate from shifting due to affecting the adsorption effect.

[0035] Reference Figure 1 , Figure 6 and Figure 7 The bottom of the air chamber 301 is fixedly connected to a negative pressure pump 302, and the top of the fixed plate frame 5 is fixedly connected to an installation platform 306. Multiple installation slots are equidistantly opened on the circumference of the installation platform 306, and installation cylinders 311 are fixedly connected in each of the multiple installation slots.

[0036] Reference Figure 1 , Figure 6 and Figure 7 Each of the multiple mounting cylinders 311 has a sliding member 312 slidably connected to its inner wall, and each of the multiple mounting cylinders 311 has a spring 313 inside it. One end of each spring 313 is fixedly connected to the inner wall of the corresponding mounting cylinder 311, and the other end is fixedly connected to the corresponding sliding member 312.

[0037] Reference Figure 1 , Figure 6 and Figure 7An annular groove 2 is provided on the mounting platform 306. A winding wheel 305 is movably connected in the annular groove 2. A motor 307 is fixedly connected to the top of the mounting platform 306. A rotating frame 308 is fixedly connected to the drive end of the motor 307. The outer wall of the rotating frame 308 is fixedly connected to the inner wall of the winding wheel 305. Multiple winding ropes 310 are surrounded around the outside of the winding wheel 305. The ends of the multiple winding ropes 310 away from the winding wheel 305 are all fixedly connected to the corresponding sliding parts 312.

[0038] Reference Figure 1 , Figure 6 and Figure 7 The bottom circumference of the air chamber 301 is fixedly connected with multiple fasteners 304 at equal intervals, and the side of the multiple sliding parts 312 away from the winding rope 310 is fixedly connected with an arc-shaped connecting rod 314. The end of the multiple arc-shaped connecting rods 314 away from the sliding parts 312 is provided with a circular hole 5. A thin rod is fixedly connected in the multiple circular holes 5. The outer wall of the multiple thin rods is movably connected with a connecting plate 309. The end of the multiple connecting plate 309 away from the arc-shaped connecting rod 314 is movably connected to the corresponding fastener 304.

[0039] In specific application scenarios, after the hard disk substrate is positioned, the motor 307 rotates the rotating frame 308, which drives the winding wheel 305 to rotate, causing the winding rope 310 to loosen. The elastic action of the spring 313 pushes the sliding member 312 and the arc-shaped connecting rod 314, forcing the connecting plate 309 to push the air chamber 301 to rise. When the suction cup 303 contacts the substrate, the negative pressure pump 302 is activated to make the air chamber 301 negative pressure. The substrate is fixed by the suction cup 303. When not in use, the suction cup 303 can be retracted into the device to prevent damage from collisions with other objects, thus improving applicability. At the same time, when in use, the suction cup 303 extends to better fit the substrate surface, ensuring the adsorption effect.

[0040] Working principle: Before turning, the air pump 217 is started to send air into the connecting chamber 212 through the connecting pipe 218, forcing the piston plate 214 to slide inside the piston cylinder 213, pushing the support rod 215 and the universal ball bearing 216 to rise, placing the hard disk substrate on the universal ball bearing 216. Then, the hydraulic rod 203 is started to push and pull the gear rod 204, which rotates the rotary table 201 through the engagement of the gear ring 202, forcing the irregular connecting rod 206 to rotate outside the fixed shaft 205, pulling the sliding table 207 and the mounting bracket 208 to move towards the center, and the substrate slides on the universal ball bearing 216 through the abutment block 210 until the substrate reaches the center position. Positioning is then initiated, followed by starting the motor 307 to rotate the rotating frame 308, which in turn drives the winding wheel 305 to rotate, causing the winding rope 310 to loosen. The elastic action of the spring 313 pushes the sliding member 312 and the arc-shaped connecting rod 314, forcing the connecting plate 309 to push the air chamber 301 upward. When the suction cup 303 contacts the substrate, the universal ball bearing 216 retracts, and the electric push rod 209 is activated to press the substrate downward through the pressing plate 211, making the substrate and the suction cup 303 fit tightly together, preventing gaps between them from affecting the adsorption effect and causing the substrate to shift. At the same time, the negative pressure pump 302 is activated to create a negative pressure state inside the air chamber 301, and the substrate is fixed by the suction cup 303.
