Support assembly

The present invention relates to a support assembly, and more particularly to a support assembly for carrying and positioning a circuit board.

With the rapid advancement of electronic technology, various electronic products have become increasingly popular in our work and life, especially the most common information and electronic products such as home appliances. In order to make these electronic products have special functions, electronic products almost all have a motherboard, which is mainly composed of many electronic components and circuit boards. Wherein, the electronic components are assembled to the circuit board and electrically connected to each other via internal wiring of the circuit board.

Take the motherboard used in the computer as an example. Some motherboards have a double-sided design (that is, many electronic components are arranged on both sides of the board). Since the double-sided design of the main board has been used in the past, since there is no suitable assembly jig, the main board can be directly placed on the work table to assemble the support bar and the input/output support frame. However, since both sides of the board are equipped with electronic components, it is easy to cause damage to the electronic components that come into contact with the desktop when the motherboard is assembled. Moreover, due to the electronic components on the board The height is different, so when the motherboard is assembled, the motherboard is easily bent due to uneven force, and the electrical connection between the circuit and the electronic components on the circuit board is damaged. In addition, since there is no assistance in assembling the jig, it is necessary to spend a lot of time on the positioning between the support bar and the main board when assembling by hand.

Currently, there is a conventional universal vehicle that includes a carrier and a support arm. The carrier plate has a plurality of screw holes for the support arms to be selectively locked. Therefore, the conventional universal carrier can cope with different specifications of the motherboard and adjust the positioning points of the support arms, thereby achieving the purpose of supporting the motherboard for double-sided assembly of electronic components. However, when the number of support arms that need to be locked is excessive, the assembler spends a lot of time in the process. If you encounter a situation where you need to mix the production, it is inevitable that you need to adjust the position of the support arm frequently, which is more time-consuming and inefficient.

The present invention provides a support assembly for fast attachment to a magnetically permeable plate. The support assembly includes a body, a magnetically permeable seat, and a rotating member. The magnetic base is disposed on the bottom surface of the body and includes two magnetic conductive portions, two non-magnetic conductive portions, and a magnet. The two magnetic conductive portions are in contact with the magnetic conductive plate. The two non-magnetic portions are connected to each other between the magnetic conductive portions. The magnetic conductive portion and the non-magnetic conductive portion surround the pivot hole. The magnet is pivotally connected to the pivot hole and has a first magnetic pole and a second magnetic pole. The rotating member is connected to the magnet and is rotatable relative to the body for driving the magnet to rotate. When the magnet rotates so that the first magnetic pole and the second magnetic pole face the magnetic conductive portion, respectively, the magnet adsorbs the magnetic conductive plate via the magnetic conductive portion. When the magnet rotates to make the first magnetic pole and the second When the magnetic poles are respectively directed to the non-magnetic conductive portions, the magnets adsorb the magnetic conductive portions.

In an embodiment of the invention, the body has a first opening, a first receiving groove, a second opening, and a second receiving groove. The first opening is located on a side of the body. The first receiving groove is formed by recessing the first opening inward. The rotating member is rotatably received in the first receiving groove and partially protrudes out of the first opening. The second opening is located on the bottom surface of the body. The second receiving groove is formed inwardly recessed by the second opening and communicates with the first receiving groove. The magnetic conductive seat is placed in the second receiving groove, and the magnetic conductive portion is exposed by the second opening.

In an embodiment of the invention, the first opening has opposite first and second edges. The rotating member includes a stopper. The stop portion protrudes beyond the first opening for selectively abutting the first edge or the second edge, thereby causing the rotating member to rotate relative to the body in a limited manner.

In an embodiment of the invention, when the rotating member rotates relative to the body such that the blocking portion abuts against the first edge, the first magnetic pole and the second magnetic pole respectively face the magnetic conductive portion. When the rotating member rotates relative to the body such that the blocking portion abuts against the second edge, the first magnetic pole and the second magnetic pole respectively face the non-magnetic conductive portion.

In an embodiment of the invention, the magnet is coaxial with the rotor.

In an embodiment of the invention, the magnetic conductive portion includes a soft magnetic material.

In an embodiment of the invention, the material of the body comprises bakelite.

In an embodiment of the invention, the outer edge of the rotating member has a non-slip structure.

In summary, the support assembly provided by the present invention can rotate the magnet by rotating the rotating member of the magnetic conductive seat, thereby selectively allowing the magnet to adsorb the magnetic conductive plate through the magnetic conductive portion, or to make the magnet only adsorb magnetically. unit. Thereby, the support assembly of the present invention can be quickly changed to a fixed position on the magnetic conductive plate. Moreover, when positioning or moving the support assembly, the assembler only needs to use one hand to move the rotating member, and does not need to use an additional disassembly tool, so it is convenient for the assembler to operate. Furthermore, the support assembly can be erected in any area of the magnetically permeable plate without dead space limitations. For the conventional universal carrier, the screw hole pitch on the carrier plate cannot be adjusted, so that the support assembly of the present invention has higher applicability to a workpiece of a special specification. In addition, the body of the support assembly for carrying the workpiece comprises a non-magnetic material and covers the inner portion of the magnetic pole, so that the effect of avoiding the influence of the magnetic force on the workpiece can be achieved.

In other words, the support assembly 12 is attached to the body 120. The bearing surface 120a1 is higher than the upper side of the workpiece 3 from the lower side of the workpiece 3, and the abutting surface 120a2 of the body 120 abuts against the edge of the workpiece 3, thereby clamping the workpiece 3 to prevent the workpiece 3 The effect of horizontal movement relative to the magnetically permeable plate 10.

Please refer to Figure 3 and Figure 4. 3 is a perspective view showing the body 120 of the support assembly 12 in FIG. 2. 4 is a perspective view showing the magnetic base 122 and the rotating member 124 of the support assembly 12 in FIG.

As shown in FIG. 2 to FIG. 4 , in the embodiment, the body 120 of the support assembly 12 further has a first opening 120 b , a first receiving groove 120 c , two second openings 120 d , and two second receiving grooves 120 e . The first accommodating groove 120c and the second accommodating groove 120e of the body 120 are indicated by broken lines in FIG. The first opening 120b of the body 120 is located on the side 120a4 of the body 120. The first accommodating groove 120c of the body 120 is formed to be recessed inward by the first opening 120b. The support assembly 12 of the present embodiment further includes two magnetic conductive seats 122 and a rotating member 124 (as shown in FIG. 4). The two magnetic conductive seats 122 of the support assembly 12 are respectively disposed at two ends of the rotating member 124. The rotating member 124 of the support assembly 12 is rotatably received in the first receiving groove 120c of the body 120 and partially protrudes beyond the first opening 120b of the body 120. The two second openings 120d of the body 120 are located on the bottom surface 120a3 of the body 120. The two second receiving slots 120e of the body 120 are recessed inwardly by the second opening 120d and communicate with the two ends of the first receiving slot 120c. The two magnetic conductive blocks 122 of the support assembly 12 are respectively received in the two second receiving grooves 120e.

As shown in FIG. 2 and FIG. 4, in the present embodiment, the magnetic conductive seat 122 of the support assembly 12 is disposed on the bottom surface 120a3 of the main body 120. The two accommodating grooves 120e include two magnetic conductive portions 122a, two non-magnetic conductive portions 122b, and a magnet 122d. The two magnetic conductive portions 122a of the magnetic conductive seat 122 and one of the non-magnetic conductive portions 122b are exposed by the second opening 120d of the body 120, and the two magnetic conductive portions 122a are for contacting the magnetic conductive plate 10. The two non-magnetic conductive portions 122b of the magnetic conductive seat 122 are connected to each other between the magnetic conductive portions 122a. The magnetic conductive portion 122a and the non-magnetic conductive portion 122b of the magnetic conductive seat 122 surround the pivot hole 122c. The magnet 122d of the magnetic base 122 is pivotally connected to the pivot hole 122c and has a first magnetic pole 122d1 and a second magnetic pole 122d2. The rotating member 124 of the supporting assembly 12 is connected to the magnet 122d of the magnetic base 122 and is rotatable in the first receiving groove 120c of the body 120, thereby driving the magnet 122d to the opposite magnetic conducting portion 122a and the non-magnetic conductive portion in the pivoting hole 122c. The portion 122b rotates. In the present embodiment, the magnet 122d of the magnetic conductive seat 122 is coaxial with the rotating member 124, as shown in FIG.

Please refer to Figure 5A and Figure 5B. Fig. 5A is a schematic cross-sectional view showing the support assembly 12 of Fig. 2 along the line segments 5A-5A' and placed on the magnetic conductive plate 10. FIG. 5B is another schematic cross-sectional view showing FIG. 5A.

As shown in FIG. 5A, in the present embodiment, when the rotating member 124 of the support assembly 12 is rotated, the magnet 122d of the magnetic conductive seat 122 is rotated to make the first magnetic pole 122d1 and the second magnetic pole 122d2 face the magnetic conductive portion, respectively. At 122a, due to the isolation of the non-magnetic conductive portion 122b, the magnetic lines of force of the magnet 122d bypass the non-magnetic conductive portion 122b and pass through the magnetic conductive plate 10 having a small magnetic resistance. Thereby, the magnet 122d of the magnetic conductive seat 122 can generate the magnetic attraction force of the magnetic conductive plate 10 via the magnetic conductive portion 122a, thereby achieving the purpose of quickly fixing the support assembly 12 to the magnetic conductive plate 10.

As shown in FIG. 5B, in the present embodiment, when the rotating member 124 of the support assembly 12 is rotated, the magnet 122d of the magnetic conductive base 122 is rotated to make the first magnetic pole 122d1 and the second magnetic pole 122d2 face non-magnetic respectively. In the portion 122b, the magnetic flux of the magnet 122d is held in the magnetic conductive holder 122 having a small magnetic resistance due to the isolation of the non-magnetic conductive portion 122b, whereby the magnetic conductive portion 122a is adsorbed. In other words, the magnetic lines of force of the magnetic conductive seat 122 do not pass through the magnetic conductive plate 10 without generating the magnetic attraction force for adsorbing the magnetic conductive plate 10 (or the magnetic flux density through the magnetic conductive plate 10 is too small to be negligible). Thereby, the purpose of quickly separating the support assembly 12 from the magnetic conductive plate 10 can be achieved.

It can be seen that the support assembly 12 of the present invention can be rapidly changed to the magnetic conductive plate 10 by selectively attracting the magnet 122d to the magnetic conductive plate 10 via the magnetic conductive portion 122a or causing the magnet 122d to adsorb only the magnetic conductive portion 122a. Fixed position on.

In the present embodiment, the first magnetic pole 122d1 of the magnet 122d is an N pole, and the second magnetic pole 122d2 is an S pole, but the invention is not limited thereto.

As shown in FIG. 2, FIG. 5A and FIG. 5B, in the present embodiment, the first opening 120b of the body 120 has an opposite first edge 120b1 and a second edge 120b2, wherein the second edge 120b2 is closer to the body 120. The bottom surface 120a3. The rotating member 124 of the support assembly 12 includes a stop portion 124a. The stopping portion 124a of the rotating member 124 protrudes beyond the first opening 120b of the body 120 for selectively abutting against the first edge 120b1 or the second edge 120b2 of the first opening 120b, thereby restricting the rotating member 124 The ground is rotated in the first receiving groove 120c of the body 120.

In the present embodiment, when the rotating member 124 of the support assembly 12 is in phase When the main body 120 is rotated such that the stopper portion 124a abuts against the first edge 120b1 of the first opening 120b (as shown in FIG. 5A), the first magnetic pole 122d1 and the second magnetic pole 122d2 of the magnet 122d are respectively oriented toward the non-magnetic conductive portion. 122b, so the user can quickly separate the support assembly 12 from the magnetically permeable plate 10. When the rotating member 124 rotates relative to the body 120 such that the blocking portion 124a abuts against the second edge 120b2 of the first opening 120b (as shown in FIG. 5B), the first magnetic pole 122d1 and the second magnetic pole 122d2 of the magnet 122d are respectively oriented. The non-magnetic conductive portion 122b allows the user to quickly separate the support assembly 12 from the magnetic conductive plate 10. When the rotating member 124 rotates relative to the body 120 such that the blocking portion 124a abuts against the first edge 120b1 of the first opening 120b (as shown in FIG. 5A), the first magnetic pole 122d1 and the second magnetic pole 122d2 of the magnet 122d are respectively directed toward the guide. The magnetic portion 122a allows the user to quickly fix the support assembly 12 to the magnetic conductive plate 10.

Therefore, it can be seen that the user can accurately rotate the magnet 122d of the magnetic base 122 by the stopping portion 124a provided on the rotating member 124, thereby rapidly switching the magnetic conductive seat 122 to the non-adsorbing magnetic conductive plate 10. The state (as shown in Fig. 5A) or the state in which the magnetic conductive plate 10 is adsorbed (as shown in Fig. 5B) does not cause a problem that the rotating member 124 is insufficiently rotated or excessively rotated.

In the present embodiment, the magnetic conductive plate 10 of the present embodiment and the magnetic conductive portion 122a of the magnetic conductive holder 122 include a soft magnetic material. Thereby, when the magnetic lines of force generated by the magnet 122d pass through the magnetic conductive plate 10 and the magnetic conductive portion 122a of the magnetic conductive seat 122 (as shown in FIG. 5B), both the magnetic conductive plate 10 and the magnetic conductive portion 122a are magnetized. In contrast, when the magnetic lines of force generated by the magnet 122d do not pass through the magnetic conductive plate 10 (or the magnetic flux density through the magnetic conductive plate 10 is too small to be negligible, as shown in FIG. 5A), only the magnetic conductive portion 122a is magnetized. And the magnetic conductive plate 10 is demagnetized.

In the present embodiment, the material of the body 120 of the support assembly 12 comprises bakelite, which is a non-magnetically permeable material. Due to the magnetic shield 122 of the support assembly 12 It is wrapped around the inside of the body 120, so that the magnetic force of the magnet 122d can be prevented from affecting the workpiece 3 during the support assembly 12 carrying the workpiece 3.

In addition, as shown in FIG. 4 to FIG. 5B, in the present embodiment, the outer edge of the rotating member 124 of the support assembly 12 has a non-slip structure, and the anti-slip structure is composed of a plurality of axial axes parallel to the rotating member 124. The groove 124b is formed. Thereby, when the user rotates the rotating member 124 of the support assembly 12, the anti-slip structure of the rotating member 124 can provide sufficient frictional force for the user to apply force to the user, but the structure of the anti-slip structure is not The implementation and drawings are limited.

From the above detailed description of the specific embodiments of the present invention, it can be clearly seen that the support assembly provided by the present invention can rotate the magnet by rotating the rotating member of the magnetic conductive seat, thereby selectively passing the magnet through the guide. The magnetic portion adsorbs the magnetic conductive plate or causes the magnet to adsorb only the magnetic conductive portion. Thereby, the support assembly of the present invention can be quickly changed to a fixed position on the magnetic conductive plate. Moreover, when positioning or moving the support assembly, the assembler only needs to use one hand to move the rotating member, and does not need to use an additional disassembly tool, so it is convenient for the assembler to operate. Furthermore, the support assembly can be erected in any area of the magnetically permeable plate without dead space limitations. For the conventional universal carrier, the screw hole pitch on the carrier plate cannot be adjusted, so that the support assembly of the present invention has higher applicability to a workpiece of a special specification. In addition, the body of the support assembly for carrying the workpiece comprises a non-magnetic material and covers the inner portion of the magnetic pole, so that the effect of avoiding the influence of the magnetic force on the workpiece can be achieved.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and those skilled in the art may, without departing from the spirit of the invention. And the scope of the invention is defined by the scope of the appended claims.
