[0033] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0034] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary.

[0040] With the development of information technology, ultra-thin hard drive substrates have gained widespread application in the data storage field due to their advantages such as small size, large capacity, and high speed. However, due to the substrate's ultra-thin structure, traditional loading fixtures often face numerous problems during the clamping, positioning, and conveying processes during the hard drive substrate turning process, such as excessive flatness, low efficiency, inaccurate positioning, and product deformation and damage. Therefore, it is particularly important to develop a clamping device specifically designed for ultra-thin hard drive substrates, specifically for lathe loading and clamping of substrates.

[0041] Please refer to the attached Figure 2 In an embodiment of the present invention, a clamping device for a base plate 40 is provided, which is used in a base plate 40 processing device to clamp the base plate 40 of a hard disk, and includes:

[0042] The mounting assembly 20 is mounted on the base plate 40 processing equipment;

[0043] A power cylinder 30 is provided on the mounting assembly 20 and is used to provide power;

[0044] At least three clamping assemblies 10 are provided on the power cylinder 30 . The three clamping assemblies 10 can be relatively close to or away from each other relative to the center, and a protective assembly is provided on the clamping assembly 10 .

[0045] It is understandable that in the turning process of the hard disk base 40, the traditional loading fixture device often faces many problems during the clamping, positioning and transportation process, such as excessive flatness, low efficiency, inaccurate positioning, and product deformation and damage.

[0046] In an embodiment, the installation component 20 and the plurality of clamping components 10 are respectively arranged on the power cylinder 30, wherein the clamping device is installed on the processing equipment through the installation component 20, and the power cylinder 30 drives the clamping component 10 so that the clamping components 10 can be relatively centered, that is, they can approach each other to grasp the base plate 40, or move away from each other to put down the base plate 40.

[0047] In actual operation, the clamping device can be installed on the base plate 40 processing equipment through the installation assembly 20 and electrically connected to the processing equipment. In the embodiment, the power cylinder 30 can be controlled to operate to drive the clamping assembly 10 provided on the power cylinder 30. The clamping assemblies 10 can be relatively centered, that is, moved closer to each other to grasp the base plate 40, or moved away from each other to put down the base plate 40. At the same time, a protective assembly is provided on the clamping assembly 10. The protective assembly can effectively protect the base plate 40 when grasping the base plate 40, thereby protecting the base plate 40.

[0048] In some embodiments, the power cylinder 30 is provided with three driving rods 31, and the clamping assemblies 10 are respectively provided on the driving rods 31. The power cylinder 30 drives the three clamping assemblies 10 to be relatively centered, that is, they can approach each other to achieve the grasping of the base plate 40, or move away from each other to achieve the lowering of the base plate 40; in some further embodiments, the power cylinder 30 is provided with four driving rods 31, and the clamping assemblies 10 are respectively provided on the driving rods 31. The power cylinder 30 drives the four clamping assemblies 10 to be relatively centered, that is, they can approach each other to achieve the grasping of the base plate 40, or move away from each other to achieve the lowering of the base plate 40; in some further embodiments, the power cylinder 30 is provided with five driving rods 31, and the clamping assemblies 10 are respectively provided on the driving rods 31. The power cylinder 30 drives the five clamping assemblies 10 to be relatively centered, that is, they can approach each other to achieve the grasping of the base plate 40, or move away from each other to achieve the lowering of the base plate 40.

[0049] Please refer to the attached Figure 1 and 2 In the embodiment, the clamping assembly 10 includes a clamping column 102 and a protective assembly, the protective assembly includes a clamping wheel 100 and an elastic member 101, one end of the clamping column 102 is connected to the power cylinder 30, the clamping wheel 100 is arranged at an end of the clamping column 102 away from the power cylinder 30, the elastic member 101 is sleeved on the clamping column 102, and the elastic member 101 is between the power cylinder 30 and the clamping wheel 100.

[0050] It is understandable that in order to solve the existing problems of the clamping device of the base plate 40,

[0051] In this embodiment, the clamping assembly 10 includes the clamping column 102 and the protective assembly. One end of the clamping column 102 is mounted on the power cylinder 30, and the power cylinder 30 can drive the clamping column 102 to move. The protective assembly is mounted on the other end of the clamping column 102, and the base plate 40 is clamped by the protective assembly. The protective assembly includes a clamping wheel 100 and an elastic member 101. The elastic member 101 is sleeved on the clamping column 102. The clamping wheel 100 can compress the elastic member 101 under pressure, so that when clamping the base plate 40, it can effectively play a role in protecting the base plate 40.

[0052] In actual operation, the power cylinder 30 drives the clamping column 102, and the clamping columns 102 move away from each other. When reaching the position of the base plate 40 to be clamped, the power cylinder 30 drives the clamping column 102, and the clamping columns 102 approach each other, and the clamping column 102 moves downward and the clamping wheel 100 hits the base plate 40. At this time, the clamping wheel 100 compresses the elastic part 101 toward the power cylinder 30 under pressure, so that even if the base plate 40 to be clamped is uneven, the protective component can ensure that the flatness of the clamped base plate 40 is high, thereby improving processing efficiency, positioning more accurately, and improving product yield.

[0053] Please refer to the attached Figure 5 In a further embodiment, the clamping wheel 100 includes a first wheel body 1000 and a second wheel body 1001 , wherein the second wheel body 1001 is disposed at one end of the first wheel body 1000 , and a groove 1002 is provided between the first wheel body 1000 and the second wheel body 1001 .

[0054] It is understood that in order to ensure that the clamping wheel 100 can accurately clamp the base plate 40, in an embodiment, the clamping wheel 100 includes a first wheel body 1000 and a second wheel body 1001. The groove 1002 between the first wheel body 1000 and the second wheel body 1001 can effectively ensure the safety of the base plate 40 when clamping, that is, the base plate 40 is stuck in the groove 1002. The first wheel body 1000 has a protruding portion, which is used to block the base plate 40. When clamping the base plate 40, the protruding portion contacts the base plate 40 to form a certain pressure, causing the elastic member 101 to compress. In this way, even if the base plate 40 is placed unevenly, the base plate 40 can be adjusted to fit the groove 1002 set by the clamping wheel 100. This embodiment ensures that the clamping wheel 100 can accurately clamp the base plate 40.

[0055] Please refer to the attached Figure 6 In a further embodiment, the diameter of the first wheel body 1000 is larger than the diameter of the second wheel body 1001.

[0056] It is understandable that in order to enable the clamping wheel 100 to accurately position when it is necessary to clamp the base plate 40, in an embodiment, the diameter of the first wheel body 1000 is set to be larger than the diameter of the second wheel body 1001, that is, the first wheel body 1000 protrudes a portion relative to the second wheel body 1001, and the protruding portion is used to block the base plate 40. When clamping the base plate 40, the protruding portion contacts the base plate 40 to form a certain degree of compression, causing the elastic member 101 to compress. In this way, even if the base plate 40 is placed unevenly, the base plate 40 can be matched with the groove 1002 set in the clamping wheel 100 through such adjustment. This embodiment enables the clamping wheel 100 to accurately clamp the base plate 40.

[0057] In some embodiments, the diameter of the first wheel body 1000 is 3 mm larger than the diameter of the second wheel body 1001; in other embodiments, the diameter of the first wheel body 1000 is 2 mm larger than the diameter of the second wheel body 1001; in still other embodiments, the diameter of the first wheel body 1000 is 5 mm larger than the diameter of the second wheel body 1001.

[0058] In a further embodiment, the width of the groove 1002 is controlled to be 0.3-0.8 mm; and the depth of the groove 1002 is controlled to be 0.8-2 mm.

[0059] It can be understood that in order to better ensure that the base plate 40 can better cooperate with the groove 1002, an embodiment is to control the width and depth of the groove 1002.

[0060] In some embodiments, the width of the groove 1002 is controlled to 0.5 mm; the depth of the groove 1002 is controlled to 1.6 mm; in other embodiments, the width of the groove 1002 is controlled to 0.3 mm; the depth of the groove 1002 is controlled to 0.8 mm; in still other embodiments, the width of the groove 1002 is controlled to 0.8 mm; the depth of the groove 1002 is controlled to 2 mm.

[0061] In a further embodiment, the clamping wheel 100 is a silicone wheel.

[0062] In order to ensure that the clamping wheel 100 can provide a certain degree of protection for the base plate 40 when clamping the base plate 40 and prevent the clamping wheel 100 from damaging the base plate 40, an embodiment is to use a soft material, specifically a silicone material to make the clamping wheel 100. The silicone wheel can protect the base plate 40 from being damaged.

[0063] Please refer to the attached Figure 4In a further embodiment, the clamping column 102 includes a column portion 1021 , a connecting portion 1022 and a blocking portion 1020 , wherein the connecting portion 1022 is provided at one end of the column portion 1021 , and the blocking portion 1020 is provided at the other end of the column portion 1021 .

[0064] It is understood that in order to mount the clamping wheel 100 on the power cylinder 30 and to enable the cylinder to clamp or release the base plate 40, in this embodiment, the clamping column 102 includes a main body, a connecting portion 1022, and a blocking portion 1020. The connecting portion 1022 is movably connected to the power cylinder 30. The elastic member 101 is a pressure spring, which is sleeved on the column portion 1021. The blocking portion 1020 cooperates with the elastic member 101 to mount the clamping wheel 100, so that the clamping wheel 100 can move linearly along the axial direction of the column portion 1021. This ensures that when the base plate 40 contacts the protruding portion of the clamping wheel 100, the pressure spring contracts upward under the action of pressure, thereby protecting the base plate 40. When the pressure spring is in its natural state, the blocking portion 1020 can prevent the clamping wheel 100 from falling off the column portion 1021.

[0065] Please refer to the attached Figure 4 In a further embodiment, the diameters of the connecting portion 1022 , the column portion 1021 and the blocking portion 1020 are different and increase in size in sequence.

[0066] The diameter of the blocking portion 1020 is set to be larger than that of the column portion 1021 to effectively ensure that the elastic member 101 will not fall off from the column portion 1021 , and the outer diameter of the column portion 1021 is smaller than the inner diameter of the elastic member 101 .

[0067] Please refer to the attached Figure 2 In a further embodiment, the mounting assembly 20 includes a mounting member 200 and a moving member, the moving member is provided on the mounting member 200, and the power cylinder 30 is installed on the moving member, and the moving member drives the power cylinder 30 to move linearly.

[0068] It can be understood that in order to install the clamping device together with the hard disk processing equipment, and to ensure that the clamping wheel 100 can contact the base disk 40, in an embodiment, the mounting assembly 20 includes a mounting part 200 and a moving part, the mounting part 200 is used for the installation of the clamping device, and the moving part can move relatively linearly. Specifically, the moving part is a cylinder, and the cylinder drives the clamping wheel 100 to move up and down, that is, the cylinder drives the clamping wheel 100 to drive the clamping wheel 100 to move downward, so that the clamping wheel 100 reaches the position of the base disk 40, and then the clamping wheel 100 clamps the base disk 40, and then the cylinder drives the clamping wheel 100 to drive the clamping wheel 100 to move upward.

[0069] Based on the same inventive concept, a hard disk processing device is also disclosed, including a device body and a clamping device for the base disk 40.

[0070] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. The present disclosure is not limited to the precise structure described above and illustrated in the accompanying drawings, and various modifications and variations may be made without departing from its scope. The scope of the present disclosure is limited solely by the appended claims. Thus, to the extent such modifications and variations fall within the scope of the claims and their equivalents, the present disclosure is intended to include such modifications and variations.
