Detailed Description
Referring to the drawings, wherein like reference numerals refer to like elements throughout, the principles of the present application are illustrated as embodied in a suitable computing environment. The following description is based on the illustrated embodiments of the present application and should not be taken as limiting other embodiments not described in detail herein.
Referring to fig. 1, 2 and 3, fig. 1 is a schematic structural diagram of a chuck according to an embodiment of the present application, fig. 2 is an enlarged view of a portion a in fig. 1, and fig. 3 is a cross-sectional view taken along line B-B in fig. 1, where the chuck 100 may be used for gripping a product to be gripped, including but not limited to an inductive product, and may be used for a subsequent winding process of the inductive product. Taking the inductance product 101 as an example, the chuck 100 comprises an adsorption component 10 and a clamping component 20, the adsorption component 10 comprises an adsorption end 11, the adsorption end 11 is positioned at the bottom end of the adsorption component 10, and the adsorption component 10 can adsorb the inductance product 101 at the adsorption end 11 from the top surface of the inductance product 101; the clamping assembly 20 comprises a clamping end 21, the clamping assembly 20 is sleeved outside the adsorption assembly 10, the clamping end 21 and the adsorption end 11 are located at the same end, and in a clamping state, the clamping end 21 exceeds the adsorption end 11, the clamping assembly 20 can clamp and adsorb the inductance product 101 at the adsorption end 11 from the side face of the inductance product 101, and after the clamping assembly 20 clamps the inductance product 101, the clamping end 21 is attached to the side face of the inductance product 101.
For example, the adsorption assembly 10 may be an adsorption tube having a hollow portion, wherein the top end of the adsorption tube is connected to an external air pressure control device, the bottom end, i.e. the adsorption end 11, adsorbs the inductance product 101, and when the adsorption end 11 of the adsorption assembly 10 contacts the top surface of the inductance product 101, the external air pressure control device sucks air, so that the hollow portion of the adsorption assembly 10 is negative pressure, thereby sucking the inductance product 101. By adsorbing the inductance product 101 by the adsorption assembly 10, the inductance product 101 can be corrected in the z-axis (vertical direction) without being skewed. The clamping assembly 20 is sleeved on the outer side of the adsorption assembly 10, and the bottom end of the clamping assembly 20 is a clamping end 21. The clamping end 21 may be a conventional clamping mechanism, such as a spring clamping structure, or may be an openable or closable clamping jaw structure, which is not particularly limited in this application. The clamping end 21 extends beyond the suction end 11, so that after the suction assembly 10 sucks the inductance product 101 at the suction end 11, the clamping assembly 20 can directly clamp the inductance product 101 from the side surface of the inductance product 101. When the inductance product 101 deflects a certain angle on the xoy plane, the clamping end 21 is attached to the side surface of the inductance product 101, so that the inductance product 101 can rotate by a corresponding angle on the xoy plane to perform calibration in the xoy plane, and angle deviation cannot occur. It will be appreciated that the clamping force of the suction assembly 10 may be released after the clamping assembly 20 clamps the inductive product 101. Compared with the adsorption force of the adsorption assembly 10 applied to the top surface of the inductance product 101, the clamping force of the clamping assembly 20 is applied to the side surface of the inductance product 101, so that the inductance product 101 can bear larger winding tension in the subsequent winding process.
It should be noted that, when the clamping end 21 exceeds the suction end 11, the clamping end 21 does not necessarily exceed the suction end 11 when the clamping end is in the non-clamping state, that is, the clamping end 21 may be flush with the suction end 11 when the clamping end is in the non-clamping state, or the suction end 11 exceeds the clamping end 21, and when the clamping end 11 is clamped, the clamping end 21 may move to exceed the suction end 11 first, and then the inductance product 101 is clamped from the side surface of the inductance product 101.
The chuck 100 in the embodiment of the application adsorbs the inductance product 101 from the top surface through the adsorption component 10, so that the inductance product 101 can be corrected in the vertical direction (z axis), and no skew in the vertical direction occurs; the clamping assembly 20 may clamp the inductive product 101 from the sides of the inductive product 101. And the clamping end 21 is attached to the side surface of the inductance product 101, so that the rotation angle of the inductance product 101 in the horizontal plane (xoy plane) can be corrected. And clamping the inductance product 101 from the side surface through the clamping assembly 20 can enable the inductance product 101 to bear larger winding tension in the subsequent winding process, and the problem that the inductance product 101 is broken or unstable in clamping and poor in winding in the subsequent process due to the fact that the inductance product 101 is skewed when the inductance product 101 is directly clamped is solved.
In an embodiment, please refer to fig. 3-8, fig. 4 is an exploded view of fig. 1, fig. 5 is a schematic structural view of an opening and closing adjustment sleeve provided in an embodiment of the present application, fig. 6 is a cross-sectional view along line C-C in fig. 5, fig. 7 is a schematic structural view of a cylindrical chuck provided in an embodiment of the present application, and fig. 8 is a schematic structural view along direction D in fig. 7. The clamping assembly 20 may include a cylindrical collet 22 and a split adjustment sleeve 23; the cylindrical chuck 22 is sleeved on the outer side of the adsorption assembly 10, at least two tearing parts 221 are arranged at one end of the cylindrical chuck 22, which is positioned at the clamping end 21, along the axial direction, and a clamping jaw 222 is formed at a part between two adjacent tearing parts 221 of the cylindrical chuck 22, and the clamping jaw 222 is in an open state when no force is applied. The open-close adjusting sleeve 23 is slidably sleeved on the outer side of the cylindrical chuck 22, the sleeved position of the open-close adjusting sleeve 23 on the cylindrical chuck 22 comprises a first limit position and a second limit position, the first limit position is far away from the clamping end 21, when the open-close adjusting sleeve 23 is located at the first limit position, the clamping jaw 222 is in an open state, and when the open-close adjusting sleeve 23 slides to the second limit position, the open-close adjusting sleeve 23 extrudes the clamping jaw 222, so that the clamping jaw 222 is closed.
To better control the jaws 222 closing and increase the holding force, a grip control structure may be provided. For example, referring to fig. 3-7, a first conical surface 223 is disposed on the outer wall of the clamping jaw 222, and one end of the first conical surface 223 near the clamping end 21 is a conical bottom, i.e. one end of the first conical surface 223 near the clamping end 21 has a larger diameter. The inner wall of the opening and closing adjusting sleeve 23 is provided with a second conical surface 231, and one end of the second conical surface 231, which is close to the clamping end 21, is a conical bottom. When the opening and closing adjustment sleeve 23 is located at the second limit position, the second conical surface 231 cooperates with the first conical surface 223, so that the opening and closing adjustment sleeve 23 presses the clamping jaw 222 and closes the clamping jaw 222. Preferably, the taper of the second taper 231 is smaller than the taper of the first taper 223 (taper = diameter of taper/height of taper), i.e. the second taper 231 is steeper, such that the second taper 231 provides a greater clamping force to the first taper 223.
It will be appreciated that the particular configuration of the cylindrical collet 22 at one end of the gripping end 21 is specifically designed according to the shape of the inductive product 101 so that the gripping end 21 conforms to the sides of the inductive product 101. For example, when the shape of the inductance product 101 is shown in fig. 2, four sides (clamping surfaces) enclose a square shape, and then one end of the cylindrical clamping head 22 located at the clamping end 21 may be provided with four tearing parts 221 along the axial direction, referring to fig. 8, so as to form four clamping jaws 222, each clamping jaw 222 is attached to one side of the inductance product 101 to clamp the inductance product 101, when the angle of the inductance product 101 is not correct, the inductance product 101 can adaptively rotate in the xoy plane during the folding and clamping process, and the four clamping jaws rotate until the side of the inductance product 101 is attached to each clamping jaw 222, so that automatic correction of the inductance product 101 in the xoy plane during the clamping process is realized.
For example, when the inductance product 101 includes only three sides, the three sides enclose a triangle, and then the end of the cylindrical chuck 22 located at the clamping end 21 can be provided with three tearing parts 221 along the axial direction, so as to form three clamping jaws 222, each clamping jaw 222 is attached to one side of the inductance product 101, so that the inductance product 101 is clamped, and the three clamping jaws can also realize automatic correction of the inductance product 101 in the xoy plane in the folding and clamping process. The principle is the same and will not be described in detail.
It will be appreciated that the cylindrical collet 22 may be made of a resilient material and that when formed, will allow the jaws 222 to be opened in a natural state. To further increase the flexibility of the gripping jaw 222, referring to fig. 7, through holes 224 may be provided in the sidewall of the cylindrical collet 22, the through holes 224 being the same as and in one-to-one correspondence with the tear-off portions 221, the tear-off portions 221 extending to communicate with the through holes 224. The through-holes 224 may further enhance the ability of the jaws 222 to resume their open configuration in a natural state.
