Description

Technical Field

[0001] This invention relates to a plate unhooking device, specifically a first fastener attached to a preset first plate and a second fastener attached to a preset second plate. The first and second fasteners are composed of solid cylindrical magnetic cores. The preset first plate can be a fixing fixture, and the preset second plate can be a workpiece. The two are stacked or interlocked. A magnetic key composed of a ring-shaped magnetic body is used to align a non-magnetic body close to the top side of the magnetic fastener with the same polarity. The magnetic lines of force are directed to change the mutual repulsion between the ring-shaped magnetic body and the magnetic fastener into a mutual attraction and adhesion state. This allows the first and second fasteners to be in a state of mutual repulsion with the same polarity, and enables the preset first and preset second plates to be unhooked and separated. This improves the problems of difficulty in unhooking and separating two solid magnets and slow processing speed in existing magnetic attraction processing operations. Furthermore, the magnetic attraction combination structure of the magnetic fastener and magnetic key proposed in this invention has the advantages of accurate alignment and no misalignment. Background Technology

[0002] With the continuous progress of the times, the manufacturing industry hopes to carry out processing, production, and transportation operations in an environment completely free of dust and fine particles. As a result, non-contact transmission methods have been developed for the transportation or fixation of various components. By utilizing the magnetic pole characteristics of magnets, magnets are embedded in the workpiece and fixture based on the principle of repulsion and attraction between the N and S poles of the magnet, and the opposite polarity attracts to temporarily fix them. After the workpiece is processed, the fixture and the magnets are removed, thereby achieving the goal of eliminating the dust-generating methods of locking, clamping, or bonding.

[0003] Current magnetic attraction machining processes use two solid magnets with opposite polarities (S and N poles) to adhere to the workpiece and fixture. As the size and weight of the workpiece and fixture increase, the magnetic force of the two solid magnets must also increase, or the number of solid magnets must be increased. While this increases the magnetic attraction between the solid magnets, it also makes it difficult to separate the two magnets, which can affect the progress of the machining process. Furthermore, as the number of solid magnets increases, the machining platform is also affected by the magnetic attraction, causing incorrect movements. Although this type of magnetic attraction machining can achieve a dust-proof effect for temporary fixation, it is difficult to solve the problems of difficult separation and slow processing speed in actual application, and needs to be improved. Summary of the Invention

[0004] Therefore, in view of the above-mentioned problems and deficiencies, the main objective of this invention is to provide a plate unhooking device.

[0005] This invention provides a plate unhooking device, comprising a magnetic buckle, including a first buckle attached to a preset first plate and a second buckle attached to a preset second plate. The first or second buckle includes a columnar magnetic body, a non-magnetic body, and a magnetic body. A magnetic key is formed by a ring-shaped magnetic body composed of N-pole magnetic bodies and S-pole magnetic bodies stacked vertically. Based on the alignment of the ring-shaped magnetic body with the non-magnetic body close to the top side of the magnetic buckle with the same polarity, the mutual repulsion state between the ring-shaped magnetic body and the magnetic buckle is changed to a mutual attraction and adhesion state by the flow of magnetic lines of force. The magnetic lines of force on the bottom side of the ring-shaped magnetic body are guided to the magnetic body on the bottom side of the magnetic buckle, so that the first buckle and the second buckle are in a state of mutual repulsion with the same polarity, and the preset first plate and the preset second plate are in an unhooked and separated state.

[0006] As described above, the first fastener attached to the first preset plate and the second fastener attached to the second preset plate are both made of solid cylindrical magnetic cores. The first preset plate can be a fixing fixture and the second preset plate can be a workpiece. The two are stacked or fitted together. A magnetic key made of a ring-shaped magnetic body is used to align a non-magnetic body close to the top side of the magnetic buckle with the same polarity. The magnetic lines of force are directed to change the mutual repulsion between the ring-shaped magnetic body and the magnetic buckle into a mutual attraction and adhesion state. This allows the first and second fasteners to be in a state of mutual repulsion with the same polarity and to form a state of unfastening and separation between the first and second preset plates. This can improve the problems of difficulty in unfastening and separation of two solid magnets and slow processing speed in the existing magnetic attraction processing operation. Moreover, the magnetic attraction combination structure of the magnetic buckle and magnetic key proposed in this invention has the advantages of accurate alignment and no misalignment.

[0007] When the annular magnetic body and the magnetic buckle are in a mutually attracted and attached state, the inner diameter of the annular magnetic body corresponds to the columnar magnetic body located on the magnetic buckle.

[0008] The magnetic key is installed in a linearly movable fixture or robotic arm; the first preset plate can be a fixture and the second preset plate can be a workpiece.

[0009] The larger the diameter of the magnetic conductor of the magnetic buckle, the more magnetic lines of force it can receive from the bottom of the annular magnetic body, and the greater the mutual repulsion force between the first buckle and the second buckle; conversely, the smaller the diameter of the magnetic conductor of the magnetic buckle, the fewer magnetic lines of force it can receive from the bottom of the annular magnetic body, and the smaller the mutual repulsion force between the first buckle and the second buckle.

[0010] The greater the height or outer diameter of the annular magnetic body, the more magnetic lines of force the magnetic buckle can receive from the bottom of the annular magnetic body, and the greater the mutual repulsion between the first and second fasteners. Conversely, the smaller the height or outer diameter of the annular magnetic body, the fewer magnetic lines of force the magnetic buckle can receive from the bottom of the annular magnetic body, and the smaller the mutual repulsion between the first and second fasteners.

Detailed Implementation

[0016] To achieve the above objectives and effects, the technical means and structure adopted by the present invention are described in detail below with reference to the preferred embodiments of the present invention, so as to facilitate a complete understanding.

[0017] Please see Figures 1-2 The figures show side sectional views of the plate unhooking device of the present invention before and after unlocking. As can be clearly seen from the figures, the fixing device of the present invention mainly includes a magnetic buckle 1 and a magnetic key 2. Its main components and features are described in detail below:

[0018] The magnetic buckle 1 includes a first buckle 11 attached to a preset first plate (not shown in the figure) and a second buckle 12 attached to a preset second plate (not shown in the figure). The preset first plate and the preset second plate are stacked or fitted together. The first buckle 11 and the second buckle 12 are mutually attracted and have the same structure. The first buckle 11 or the second buckle 12 includes a columnar magnetic body (111, 121) made of S-pole magnetic body and N-pole magnetic body stacked vertically. A non-magnetic body (112, 122) is provided on the top side of the columnar magnetic body (111, 121) and a magnetic body (113, 123) is provided on its bottom side.

[0019] The magnetic key 2 is composed of a ring-shaped magnetic body 21 formed by vertically stacking N-pole magnetic bodies 211 and S-pole magnetic bodies 212. The ring-shaped magnetic body 21 has a hollow inner diameter. And the inner diameter Approximately equal to the diameter of the columnar magnetic body (111, 121) Based on the fact that the annular magnetic body 21 is aligned with the non-magnetic body 112 on the top side of the magnetic buckle 1 with the same polarity and there is a buckling gap G1, the mutual repulsion state between the annular magnetic body 21 and the magnetic buckle 1 is changed to a mutual attraction and adhesion state by the flow of magnetic lines of force. The magnetic lines of force on the bottom side of the annular magnetic body 21 are guided to the magnetic body 113 on the bottom side of the magnetic buckle 1, so that the first buckle 11 and the second buckle 12 are in a state of mutual repulsion with the same polarity and there is a mutual repulsion gap G2, and the preset first plate and the preset second plate are in a state of buckling separation.

[0020] When the aforementioned annular magnetic body 21 and the magnetic buckle 1 are in a mutually attracted and adhered state, the inner diameter of the annular magnetic body 21 For the columnar magnetic body (111, 121) located in the magnetic buckle 1.

[0021] The aforementioned magnetic key 2 is installed in a linearly movable fixture (not shown in the figure) or a robotic arm (not shown in the figure); and the preset first plate can be a fixture (not shown in the figure) and the preset second plate can be a workpiece (not shown in the figure).

[0022] The aforementioned columnar magnetic bodies (111, 121) are composed of cylinders, elliptical cylinders, rectangular cylinders, hexagonal cylinders, or polygonal cylinders; while the ring-shaped magnetic body 21 is composed of circular rings, elliptical rings, rectangular rings, hexagonal rings, or polygonal rings; the non-magnetic bodies (112, 122) are composed of plastic or acrylic materials; and the magnetic bodies (113, 123) are composed of iron, iron alloys, stainless steel, or nickel alloys.

[0023] The aforementioned magnetic conductors (113, 123) are implemented using iron sheets, so that the first fastener 11 attached to the preset first plate (fixed fixture) and the second fastener 12 attached to the preset second plate (processed object) generate mutual attraction and repulsion between them and the magnetic key 2 attached to the linearly movable fixture or robotic arm. Therefore, the magnetic conductors (113, 123) are not necessarily designed in the form of iron sheets. Alternatively, powders with magnetic attraction properties, such as iron powder, can be coated on the bottom side of the columnar magnetic body (111, 121) in the form of paint so that the magnet 21 can generate a magnetic attraction effect. Thus, the bottom side of the columnar magnetic body (111, 121) only needs to have magnetic conductivity. This simple and uniform variation and modification does not limit the scope of protection of the present invention and is hereby explained.

[0024] As described above, when this invention is applied in an automated assembly plant, the processing machine is provided with an annular magnetic body 21 that aligns with the non-magnetic body 112 on the top side of the magnetic buckle 1, which is a magnetic key 2 of a linear moving fixture or robotic arm, with the same polarity. The magnetic lines of force are directed to change the repulsive state between the annular magnetic body 21 and the first fastener 11 attached to the fixing fixture into an attractive and bonded state, thus achieving a non-locking, non-clamping, and non-adhesive fixing structure that does not generate dust. Furthermore, the magnetic force on the bottom side of the annular magnetic body 21... The wire is guided to the magnetic conductor 113 on the bottom side of the first fastener 11, so that the second fastener 12 attached to the workpiece being fixed is in a state of mutual repulsion with the first fastener 11, and the fixing fixture and the workpiece are in a state of unfastening separation. Furthermore, more workpieces (not shown in the figure, such as a third fastener, a fourth fastener, or more fasteners) can be magnetically attracted below the aforementioned second fastener 12. This simple variation is also within the protection scope of this invention. The magnetic key 2 simultaneously unfastens all workpieces. The first fastener 11 (fixing fixture) attracted to the magnetic key 2 is then moved to its original position on the processing machine via a linear moving fixture or robotic arm, and waits for the next set of workpieces to arrive at the processing station positioning point before magnetically fixing the workpieces.

[0025] Please see Figure 3 , Figure 4 The figures shown are of the first and second embodiments of the magnetic key of the present invention after unlocking, wherein the diameter of the magnetic conductor (113, 123) of the magnetic clasp 1 is shown. The larger the diameter, the more magnetic lines of force can be received from the bottom side of the annular magnetic body 21, and the greater the mutual repulsion force between the first fastener 11 and the second fastener 12 (the mutual repulsion distance G2 becomes larger); conversely, the smaller the diameter, the greater the number of magnetic lines of force received from the bottom side of the annular magnetic body 21, and the greater the mutual repulsion force between the first fastener 11 and the second fastener 12 (the mutual repulsion distance G2 becomes larger); The smaller the size, the fewer magnetic lines of force can be received from the bottom side of the annular magnetic body 21, and the smaller the mutual repulsion force between the first fastener 11 and the second fastener 12 (the mutual repulsion distance G2 becomes smaller); while the size of the magnetic conductor will cause the repulsive force to rebound within a certain range. The test data for various dimensions of the magnetic fastener 1, the annular magnetic body 21, and the magnetic conductors (113, 123) are shown in the table below:

[0026]

[0027] Please see Figure 3 , Figure 4 As shown, the height H1 or outer diameter of the annular magnetic body 21 is... The larger the diameter, the more magnetic lines of force the magnetic conductor 113 of the magnetic buckle 1 can receive from the bottom side of the annular magnetic body 21, and the greater the mutual repulsion force between the first fastener 11 and the second fastener 12 (the mutual repulsion distance G2 becomes larger); conversely, the smaller the diameter, the greater the number of magnetic lines of force the annular magnetic body 21 can receive from the bottom side of the magnetic conductor 113 of the magnetic buckle 1, and the greater the mutual repulsion force between the first fastener 11 and the second fastener 12 (the greater the mutual repulsion distance G2); The smaller the size, the fewer magnetic lines of force that the magnetic conductor 113 of the magnetic buckle 1 can receive from the bottom side of the annular magnetic body 21, and the smaller the mutual repulsion force between the first fastener 11 and the second fastener 12 (the mutual repulsion distance G2 becomes smaller).

[0028] To verify Figure 3 , Figure 4 The provided technical content, in particular, mentions the height of the annular magnetic body 21; the number of magnetic lines of force of the magnetic conductors (113, 123); and a comparison table of the mutual repulsion distance G2 generated between the first fastener 11 and the second fastener 12, as follows:

[0029]

[0030] The main features of this invention are as follows: the first fastener 11 attached to the first preset plate and the second fastener 12 attached to the second preset plate are both made of solid cylindrical magnetic cores. The first preset plate can be a fixing fixture and the second preset plate can be a workpiece. The two are stacked or fitted together. The magnetic key 2, which is made of an annular magnetic body 21, is aligned with the non-magnetic body 112 close to the top side of the magnetic buckle 1 with the same polarity. The mutual repulsion between the annular magnetic body 21 and the magnetic buckle 1 is changed to mutual attraction and adhesion through the flow of magnetic lines of force. This makes the first fastener 11 and the second fastener 12 present a state of mutual repulsion with the same polarity, and makes the first preset plate and the second preset plate form a state of unfastening and separation. This can improve the problems of difficulty in unfastening and separation of two solid magnets and slow processing speed in the existing magnetic attraction processing operation. Moreover, the magnetic attraction combination structure of the magnetic buckle 1 and the magnetic key 2 proposed in this invention has the advantages of accurate alignment and no misalignment.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, any simple modifications and equivalent structural changes made based on the description and drawings of the present invention should also be included within the protection scope of the present invention and are hereby stated.

[0032] In summary, the above-mentioned plate unhooking device of the present invention can reliably achieve its function and purpose when in use, thus the present invention is indeed an invention with excellent practicality.
