Abstract
Description
Technical Field
[0001] This invention relates to the field of computer product manufacturing technology, and more specifically, to an automated intelligent processing equipment for computer internal components. Background Technology
[0002] Hard disks are closely linked to the development of computer technology and are a crucial component of modern computing systems. As the primary data storage device, the hard disk plays a central role in computer systems. Operating systems, applications, and user data all need to be stored on hard disks for long-term storage and easy access.
[0003] As an important component of a computer system, the quality and storage capacity of a hard drive determine the performance of the computer system to a certain extent. Therefore, it is necessary to ensure that the hard drive has good quality during the manufacturing process.
[0004] Among them, helium hard drives are a type of mechanical structure based on traditional hard drives, but instead of ordinary air, they use helium gas to fill the interior. This greatly shortens the distance between the platters, allowing them to be placed closer together, further improving the utilization of hard drive space and thus relatively increasing the storage capacity of the hard drive.
[0005] In order to ensure that the helium hard drive cavity maintains a high-purity helium environment (concentration >99.99%), unlike traditional mechanical hard drives, helium hard drives require effective welding and sealing of the casing. In the traditional solution, the device is first placed in a vacuum environment for welding, and a displacement hole or displacement tube structure is reserved on the casing. After welding, it is moved to a transition chamber, filled with helium to displace the helium into the hard drive casing, and finally the displacement hole or displacement tube is sealed.
[0006] However, traditional welding methods involve relatively complex procedures and have low actual welding efficiency. Furthermore, the secondary sealing of the replacement holes can easily lead to poor sealing quality and affect the sealing effect. Summary of the Invention
[0007] The present invention provides an automated intelligent processing equipment for computer internal components. The problem to be solved is that traditional welding methods have relatively complex process steps, low actual welding efficiency, and the secondary sealing of replacement holes can easily lead to poor sealing quality and affect the sealing effect.
[0008] To achieve the above objectives, the present invention provides the following technical solution: an automated intelligent processing equipment for computer internal components, including a laser welding gun and a hard disk fixture, the hard disk fixture being used to carry a helium hard disk, both the laser welding gun and the hard disk fixture being disposed in a helium chamber, and both the helium chamber and the helium hard disk being filled with helium.
[0009] The helium chamber is also equipped with a welding torch drive assembly and a hard disk drive assembly. The welding torch drive assembly is used to drive the laser welding torch to move, and the hard disk drive assembly is used to drive the hard disk fixture to move, so that the laser beam emitted by the laser welding torch moves along the path of the weld seam on the top of the helium hard disk and performs welding.
[0010] The laser welding gun is also equipped with a pressure chamber with an open bottom. A sealed platform is provided in the helium chamber corresponding to the outer area of the hard disk fixture. An inflation pipe is also fixedly installed on the pressure chamber. The inflation pipe is connected to a pressurizing device through a pipeline. The pressurizing device is used to increase the helium pressure in the pressure chamber.
[0011] In a preferred embodiment, a top pressure device is also provided above the hard disk fixture. A positioning pressure plate is fixedly installed at the output end of the bottom of the top pressure device. The top pressure device is used to drive the positioning pressure plate to move up and down. An adsorption and lifting assembly for adsorbing the cover plate on the top of the helium hard disk is provided at the bottom of the positioning pressure plate. Side extension frames are fixedly installed in the areas corresponding to the four edges of the cover plate around the positioning pressure plate. A pressure bar is installed at the bottom of the side extension frame for contacting the cover plate and forming a squeezing restriction on the cover plate.
[0012] In a preferred embodiment, the welding torch drive assembly includes a lifting driver and a lifting base. The laser welding torch is fixedly mounted on the lifting base, which is mounted on the output end of the lifting driver. The lifting driver is mounted in a helium chamber and is used to drive the lifting base to move along the Z-axis.
[0013] In a preferred embodiment, the helium chamber is provided with multiple sets of hard disk fixtures, and the welding torch drive assembly further includes a second longitudinal drive and a second transverse drive. The lifting drive is installed at the output end of the second longitudinal drive, and the second longitudinal drive is installed at the output end of the second transverse drive. The multiple sets of hard disk fixtures are distributed along the transverse direction of the second transverse drive. The second transverse drive is used to drive the laser welding torch to move laterally along the X-axis direction, and the second longitudinal drive is used to drive the laser welding torch to move longitudinally along the Y-axis direction.
[0014] In a preferred embodiment, the hard disk drive assembly includes a first longitudinal drive and a first transverse drive. The first longitudinal drive is mounted on a support platform inside the helium chamber, and the first transverse drive is mounted on the output end of the first longitudinal drive. The hard disk fixture is mounted on the output end of the first transverse drive. The first longitudinal drive is used to drive the hard disk fixture to move longitudinally along the Y-axis, and the first transverse drive is used to drive the hard disk fixture to move laterally along the X-axis.
[0015] In a preferred embodiment, the hard disk drive assembly further includes a rotary drive housing, which is mounted on the output end of the first transverse drive, and the hard disk fixture is fixedly mounted on the output end of the rotary drive housing.
[0016] In a preferred embodiment, the pressure unit is fixedly connected to the output end of the first transverse drive via a side extension frame. The pressure unit is rotatably mounted on the side extension frame, which is also provided with a rotation driver for driving the side extension frame to rotate. The rotation driver is used to drive the pressure unit and the hard disk fixture to rotate synchronously and coaxially.
[0017] In a preferred embodiment, the adsorption and lifting component is a vacuum suction cup, which is a corrugated tube type suction cup. The vacuum suction cup is connected to a vacuum pumping device through a pipe. When the vacuum suction cup forms a vacuum adsorption on the cover plate, the vacuum suction cup contracts vertically, thus lifting the cover plate upwards.
[0018] In a preferred embodiment, the adsorption lifting assembly is a cooling adsorption assembly, which includes a rubber adsorption cover and a low-temperature fluid chamber. The rubber adsorption cover is fixedly installed on the bottom of the positioning pressure plate, and the bottom of the rubber adsorption cover is used to contact the cover plate and form a seal. The low-temperature fluid chamber is disposed in the rubber adsorption cover and is fixedly connected to the positioning pressure plate. A low-temperature fluid circulation pipe is provided on the low-temperature fluid chamber, and the low-temperature fluid circulation pipe is connected to a low-temperature fluid circulation system, which is used to input cold water into the low-temperature fluid chamber.
[0019] In a preferred embodiment, the pressure bar is rotatably mounted on the side extension frame, and a pad is placed between the bottom of the pressure bar and the cover plate. One end of the pad near the center area of the cover plate is connected to the side extension frame through an elastic connection part. The pad and the elastic connection part are an integral elastic sheet structure.
[0020] The beneficial effects of this invention are as follows:
[0021] 1. This invention allows for laser welding of hard drive casings directly in a helium atmosphere. The helium hard drive can be pre-filled with helium, and after welding, a helium hard drive is obtained directly without the need for replacement. This reduces processing steps, lowers the production cost of helium hard drives, and consequently reduces the production cost of corresponding computer components, effectively improving production efficiency. Furthermore, laser welding has no requirements for the gas environment and will not affect normal welding.
[0022] 2. This invention further fills the pressurization chamber with helium using a pressurizing pump to increase the helium pressure inside the chamber and the helium hard drive. During the actual welding process, although some helium overflows from the weld seam at the unwelded area, the amount of helium inside the hard drive casing decreases after overflow, but it is still close to the amount of helium in a helium hard drive at normal pressure. Therefore, after welding is completed, the pressurization chamber is removed from the sealed platform, and the helium hard drive finally cools to room temperature. Since the amount of helium in the helium hard drive is not much different from that in a helium hard drive at normal pressure, the resulting pressure difference is extremely small, thus not affecting the normal use of the helium hard drive. This further improves the production quality of the helium hard drive, thereby indirectly improving the performance and lifespan of the corresponding computer equipment. Attached Figure Description

[0035] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0036] Refer to the instruction manual appendix Figure 1 and Figure 2 An automated intelligent processing device for computer internal components includes a helium chamber 1, a laser welding gun 2 and a hard disk fixture 3 disposed within the helium chamber 1. The hard disk fixture 3 is used to support a helium-filled hard disk 4. The helium-filled hard disk 4 includes a hard disk housing 41 and a cover plate 42. The hard disk fixture 3 is provided with a slot structure for positioning the hard disk housing 41. After the hard disk housing 41 is installed, the open side of the hard disk housing 41 faces upward, and a slot structure for mounting and engaging the cover plate 42 is provided on the open side of the hard disk housing 41. A weld seam 43 is formed in the area between the top of the hard disk housing 41 and the edge of the cover plate 42 to facilitate subsequent welding.
[0037] Since weld seam 43 is rectangular, the welding trajectory of laser welding gun 2 is also rectangular. Therefore, it is necessary to drive relative movement between laser welding gun 2 and helium hard disk 4. Thus, welding gun drive assembly 21 and hard disk drive assembly 31 are also provided in helium chamber 1. Welding gun drive assembly 21 is used to drive the movement of laser welding gun 2, and hard disk drive assembly 31 is used to drive the movement of hard disk fixture 3. (Refer to the attached instruction manual.) Figure 2 and Figure 4The welding torch drive assembly 21 includes at least a lifting driver 212 and a lifting base 211. The laser welding torch 2 is fixedly mounted on the lifting base 211, which is mounted on the output end of the lifting driver 212. The lifting driver 212 is installed inside the helium chamber 1. The lifting driver 212 drives the lifting base 211 to move along the Z-axis to achieve lifting and lowering of the laser welding torch 2, thereby causing the laser welding torch 2 to descend to a specified height when welding is required, so that the laser is focused at the weld seam 43, causing the material at the weld seam 43 to melt and form a weld. The hard disk drive assembly 31 includes a first longitudinal drive. The first longitudinal driver 311 is mounted on the support platform inside the helium chamber 1, and the first transverse driver 312 is mounted on the output end of the first longitudinal driver 311. The hard disk fixture 3 is mounted on the output end of the first transverse driver 312. The first longitudinal driver 311 drives the hard disk fixture 3 to move longitudinally along the Y-axis, and the first transverse driver 312 drives the hard disk fixture 3 to move laterally along the X-axis, thereby realizing bidirectional movement drive of the hard disk fixture 3 along the X and Y axes, so that the laser beam emitted by the laser welding gun 2 moves along the path of the weld seam 43. In addition to welding, to make full use of space in the helium chamber 1, two or more sets of hard disk fixtures 3 can be set up in the helium chamber 1 for sequential welding by the laser welding gun 2. The welded helium hard disks 4 are then cooled in the helium chamber 1 to save processing time. For this purpose, a drive source for the laser welding gun 2 can be added. For example, the welding gun drive assembly 21 also includes a second longitudinal drive 213 and a second transverse drive 214. The lifting drive 212 is installed at the output end of the second longitudinal drive 213, and the second longitudinal drive 213 is installed at the output end of the second transverse drive 214. At the output end, multiple sets of hard disk fixtures 3 are distributed along the transverse direction of the second transverse drive 214. The second transverse drive 214 is used to drive the laser welding gun 2 to move laterally along the X-axis, and the second longitudinal drive 213 is used to drive the laser welding gun 2 to move longitudinally along the Y-axis. This increases the number of movable directions of the laser welding gun 2, further improving the welding flexibility of the laser welding gun 2. It can also drive the laser welding gun 2 to perform multi-station moving processing. According to the welding program of the corresponding helium hard disk 4, it can drive the laser welding gun 2 to perform automated movement and automated welding, thus forming an automated intelligent welding system.
[0038] For easy insertion of the helium hard drive 4, please refer to the instruction manual. Figure 3The helium chamber 1 is equipped with a sealing door 12 for sealing the helium chamber 1. Simultaneously, the helium chamber 1 is equipped with a helium filling device, such as a vacuum pump and a filling pump. The vacuum pump removes the existing air from the helium chamber 1, and the filling pump introduces helium into the helium chamber 1, thus filling it with helium. This allows the helium-filled hard drive 4 to be soldered in a helium environment (before soldering, the hard drive casing 41 and cover plate 42 are not sealed, so the internal air can be exchanged, allowing the helium-filled hard drive 4 to be filled with helium in a helium environment). This ensures that the helium-filled hard drive 4 is pre-filled with helium during soldering, and after soldering, the helium-filled hard drive 4 is obtained directly without the need for replacement, reducing processing steps, lowering the production cost of the helium-filled hard drive 4, and consequently reducing the production cost of the corresponding computer components, effectively improving production efficiency.
[0039] In the above embodiments, laser welding of the hard disk casing can be performed directly in a helium environment. That is, the interior of the helium-filled hard disk 4 is already filled with helium during welding, and laser welding has no requirements for the gas environment, so it will not affect normal welding. However, during the welding process, the gas inside the hard disk casing 41 will experience a certain degree of temperature rise and expansion. After welding is completed, the hard disk casing 41 and the cover plate 42 are completely sealed. As the temperature gradually decreases, the helium inside the hard disk casing 41 contracts, forming a negative pressure. This causes the hard disk casing 41 and the cover plate 42 to be constantly subjected to uneven gas pressure, affecting the long-term use of the helium-filled hard disk 4. Especially for larger helium-filled hard disks 4, the amount of gas in their internal cavity is relatively large, resulting in a relatively large negative pressure. This makes it easier for the hard disk casing 41 and the cover plate 42 to deform later, affecting the normal installation and use of the helium-filled hard disk 4 in the computer system. Therefore, this embodiment provides the following technical solution, specifically referring to the appendix to the specification. Figure 2 and Figure 4 The laser welding gun 2 is also equipped with a pressure chamber 22. The bottom of the pressure chamber 22 is open. A sealing platform 11 is provided in the helium chamber 1 corresponding to the outer area of the hard disk fixture 3. The sealing platform 11 is used to contact the bottom opening of the pressure chamber 22 and form a seal. Specifically, when welding is required, the laser welding gun 2 is driven to descend for welding, which also drives the pressure chamber 22 to descend and contact the sealing platform 11. The area of the pressure chamber 22 corresponding to the sealing platform 11 is equipped with a sealing structure, such as a rubber sealing gasket. After the pressure chamber 22 contacts the sealing platform 11, a secondary sealed cavity is formed. Refer to the attached instruction manual. Figure 5The hard drive fixture 3 moves within the pressure chamber 22 to ensure that the helium-filled hard drive 4 is welded within the area of the laser welding gun 2. Simultaneously, an inflation pipe 221 is fixedly installed on the pressure chamber 22, which is connected to a pressurizing device—a pressure pump connected to a helium source. This pump further injects helium into the pressure chamber 22, increasing the helium pressure inside the chamber and the hard drive 4. Therefore, before welding begins, the hard drive 4 is under high pressure, and its actual helium content is higher than under normal pressure. Thus, during the actual welding process, although the hard drive 4 and the helium inside it expand due to temperature rise... This process allows some helium to escape from the weld seam 43 at the unwelded area of the hard drive casing 41. Although the amount of helium in the hard drive casing 41 decreases after the escape, it is still close to the amount of helium in the helium hard drive 4 at normal pressure. Therefore, after welding is completed, the pressure box 22 is removed from the sealed platform 11, and the helium hard drive 4 finally cools down to room temperature. Since the amount of helium contained in the helium hard drive 4 is not much different from the amount of helium in the helium hard drive 4 at normal pressure, the resulting pressure difference is extremely small. This will not affect the normal use of the helium hard drive 4, further improving the production quality of the helium hard drive 4, thereby indirectly improving the performance and lifespan of the corresponding computer equipment.
[0040] In the above scheme, some laser welding systems also need to blow helium gas to the laser focus point simultaneously during welding to remove slag and spatter. Therefore, in order to ensure the stability of the helium pressure in the pressurization box 22, an exhaust pipe 222 needs to be installed on the pressurization box 22 and connected to the exhaust equipment. At the same time, a pressure relief valve is installed on the exhaust equipment to ensure the stability of the internal pressure of the pressurization box 22 during welding.
[0041] Furthermore, for helium hard drives 4 with higher welding requirements, a more robust weld quality is needed. This necessitates sufficient welding time, a moderate welding speed, and a weld size to ensure complete fusion of the molten material. Therefore, during the actual welding process, the hard drive casing 41 and the cover plate 42 are heated for a longer period, causing them to expand. The cover plate 42, being a thin plate structure with the welding area primarily at the top, experiences greater thermal expansion during welding. This expansion between the cover plates 42 compresses the weld, reducing its size. Conversely, after cooling, the cover plates 42 contract, potentially stretching the weld area and leading to cracking or weld spalling. To address these issues, this embodiment provides the following technical solutions, as detailed in the appendix. Figure 6The hard disk drive assembly 31 also includes a rotary drive base 313, which is mounted on the output end of the first transverse drive 312. The hard disk fixture 3 is fixedly mounted on the output end of the rotary drive base 313, thereby enabling the rotary drive base 313 to drive the hard disk fixture 3 and the helium hard disk 4 to rotate. In addition, a pressure device 5 is provided above the hard disk fixture 3. The pressure device 5 is fixedly connected to the output end of the first transverse drive 312 through a side extension frame 53. That is, the side extension frame 53 is fixedly connected to the fixed part of the rotary drive base 313, thereby avoiding the laser welding gun 2. The pressure device 5 is rotatably mounted on the side extension frame 53, and the side extension frame 53 is also provided with a rotating mechanism for driving the side extension frame 53 to rotate. A rotary actuator is used to drive the pressure unit 5 and the hard disk fixture 3 to rotate synchronously and coaxially. A positioning pressure plate 51 is fixedly installed at the output end of the bottom of the pressure unit 5. The pressure unit 5 is used to drive the positioning pressure plate 51 to move up and down. The bottom of the positioning pressure plate 51 is provided with an adsorption lifting assembly 52 for adsorbing the cover plate 42. Side extension frames 53 are fixedly installed around the positioning pressure plate 51 in the areas corresponding to the four edges of the cover plate 42. The bottom end of the side extension frame 53 is provided with a pressure bar 531 for contacting the cover plate 42 and forming a squeezing restriction on the cover plate 42. In addition to adsorbing the cover plate 42, the adsorption lifting assembly 52 also has the function of lifting the adsorption area upward. For details, please refer to the appendix of the instruction manual. Figure 7 and Figure 8 The suction and lifting assembly 52 uses a vacuum suction cup 521, which is a corrugated tube type suction cup. The vacuum suction cup 521 is connected to a vacuum pump via a pipe. When the vacuum suction cup 521 forms a vacuum suction on the cover plate 42, as the vacuum pump continues to pump, the vacuum suction cup 521 also contracts vertically, thus lifting the cover plate 42 upwards. At this time, the height of the positioning plate 51 remains unchanged, and the heights of the edge rods 531 also remain unchanged. That is, the four edge areas of the cover plate 42 are still in contact with and adhere to the hard drive casing 41. However, due to the upward deformation tendency of the central area of the cover plate 42, refer to the attached instruction manual. Figure 9 This causes the four edges of the cover plate 42 to tend to shift inward. After welding is completed and the adsorption and lifting assembly 52 is removed, the edges of the cover plate 42 tend to move outward and squeeze. This counteracts the tension on the welded part caused by the expansion and then contraction of the cover plate 42 during the welding process, further improving the welding quality of the helium hard disk 4.
[0042] In addition, the aforementioned pressure device 5 can drive the positioning plate 51 to rise and fall. Therefore, initially, the hard disk housing 41 is placed in the hard disk fixture 3, and the cover plate 42 is precisely adsorbed under the positioning plate 51 by other positioning fixtures. When helium is filled and replaced in the helium chamber 1, it can be ensured that the air in the hard disk housing 41 can be replaced more fully. Then, the pressure device 5 drives the positioning plate 51 to fall so that the cover plate 42 is spliced with the hard disk housing 41.
[0043] In the above embodiments, due to the adsorption lifting assembly 52 and the side extension frame 53, the problem caused by the expansion of the cover plate 42 can be fully solved. Therefore, in order to reduce the temperature difference generated by the materials during the welding process, the helium hard disk 4 and the hard disk casing 41 can also be preheated as a whole. For example, a heater 223 is also fixedly installed inside the pressurization box 22. The heater 223 can be a resistance heating device, and the helium source connected to the pressurization pump connected to the inflation pipe 221 can also be a high-temperature helium source. However, it should be noted that the helium pressure in the pressurization box 22 increases further after heating, but the overall amount does not change. Therefore, the pressure limit in the pressurization box 22 during actual operation also needs to be adjusted.
[0044] Furthermore, in addition to the aforementioned vacuum suction cup 521 serving as the adsorption and lifting assembly 52, this embodiment also provides another adsorption and lifting assembly 52, namely, a cooling adsorption assembly 52. The cooling adsorption assembly includes a rubber adsorption cover 522 and a low-temperature fluid chamber 54. The rubber adsorption cover 522 is fixedly installed at the bottom of the positioning plate 51, and its bottom is used to contact the cover plate 42 and form a seal. The low-temperature fluid chamber 54 is disposed within the rubber adsorption cover 522 and is fixedly connected to the positioning plate 51. A low-temperature fluid circulation pipe 541 is provided on the low-temperature fluid chamber 54, which includes an input pipe and an output pipe. The low-temperature fluid circulation pipe 541 is connected to a low-temperature fluid circulation system, i.e., a cold water circulation pump. The input pipe is connected to... A circulating pump continuously supplies cold water into the cryogenic fluid chamber 54 to cool the area between the rubber adsorption cover 522 and the cover plate 42. For example, the cover plate 42 is attached to the hard disk housing 41. Before welding begins, cold water is supplied into the cryogenic fluid chamber 54 to lower the temperature of the helium gas in the rubber adsorption cover 522, thereby creating a negative pressure that adsorbs the cover plate 42. As the cooling rate increases, the central area of the cover plate 42 is also drawn upward, thus lifting the cover plate 42. At the same time, due to the temperature reduction in the rubber adsorption cover 522, the temperature in the central area of the cover plate 42 also decreases relatively. Therefore, the central area of the cover plate 42 will experience relative cooling and contraction to counteract the thermal expansion of the edges of the cover plate 42, further improving the welding effect.
[0045] Since the pressure bar 531 mainly exerts downward pressure on the cover plate 42, the cover plate 42 will experience slight movement relative to the pressure bar 531 during the above operation. Therefore, to avoid wear, this embodiment also provides the following solution, as shown in the appendix to the specification. Figure 10 The pressure bar 531 is rotatably mounted on the side extension frame 53. A pad 532 is placed between the bottom of the pressure bar 531 and the cover plate 42. One end of the pad 532 near the center of the cover plate 42 is connected to the side extension frame 53 through an elastic connecting part 533. The pad 532 and the elastic connecting part 533 are an integral elastic sheet structure. In actual use, the pad 532 acts as a transition structure to protect the helium hard disk 4, while the elastic connecting part 533 provides elastic support for the pad 532. When the cover plate 42 bulges upward in the middle, the pad 532 can mitigate the deformation of the cover plate 42 at the pressure bar 531, thereby avoiding excessive deformation and irreversible damage.
[0046] In addition, please refer to the appendix to the instruction manual. Figure 11 To improve the welding quality of the helium hard disk 4, the structure of the helium chamber 1 and the cover plate 42 can be improved. For example, a material-adding part 44 can be provided on the top near the weld 43 of the hard disk housing 41 and the cover plate 42. The material-adding part 44 is protruding and is equivalent to the preset solder. The weld 43 is provided with a receiving space. During welding, the presence of the material-adding part 44 will increase the molten material, and some of the molten material will enter the receiving space for full fusion, thereby improving the welding quality.
[0047] It should be noted that in order to improve the relative movement freedom of the laser welding gun 2 during welding, multiple sets of drivers are set in this embodiment, so that it can also cope with other processing requirements besides those described in this embodiment. The various moving drivers, rotating drivers and rotating drive seats 313 mentioned above are all linear drive devices such as cylinders and linear motors commonly used in the industrial production field, as well as rotating motors and automatic rotating chassis structures. Therefore, this embodiment will not explain them in detail. In actual use, the selection of each driver can be reduced or added according to actual needs. For example, when using the rotating drive seat 313 and the first longitudinal driver 311 in combination, the first transverse driver 312 can also be omitted, and the rotating drive seat 313 can be directly set on the output end of the first longitudinal driver 311.
[0048] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
