These embodiments are merely examples and are not intended to limit the scope and application of the present invention. Moreover, the relative thicknesses and positions of various components, layers or regions may be reduced or exaggerated for clarity.

Fig. 1A is a schematic perspective view of a substrate conveying apparatus according to a first embodiment of the invention.

Referring to fig. 1A, the substrate transportation apparatus 100 of the present embodiment at least includes a driving device 102, a transportation rail 104, and a plurality of magnetic balls 106. The driving device 102 includes an actuator 108, and a plurality of first screws 110 and a plurality of second screws 112 driven by the actuator 108 to rotate, wherein a position of each first screw 110 is relative to a position of each second screw 112. For example, if the substrate 114 is continuously transported in a vertical manner, the transport path 116 of the substrate 114 is located between each first screw 110 and each second screw 112. Also, the distance d1 between the two first screws 110 is preferably the same as the distance d2 between the two second screws 112. In one embodiment, the substrate 114 is a printed circuit board, but the invention is not limited thereto.

Referring to fig. 1A, the conveying track 104 is provided with a plurality of clamps 118 for clamping the substrate 114, and the conveying track 104 moves toward the conveying path 116. Although only 4 grippers 118 are shown in fig. 1A, it should be understood that the length of the conveying track 104 can reach several tens of meters, and the grippers 118 are usually distributed at equal intervals on the whole conveying track 104 for continuous conveying of the substrates 114. The magnetic balls 106 are respectively disposed in the first screws 110 and the second screws 112, so as to stabilize the vertically conveyed substrate 114 by the magnetic attraction or repulsion between the magnetic balls 106 in each first screw 110 and the magnetic balls 106 in each second screw 112. The position and size of the magnetic balls 106 can be changed according to the requirement, for example, the magnetic balls 106 disposed in the first screw 110 are respectively disposed corresponding to the magnetic balls 106 disposed in the second screw 112 in position, so that the distance between the two screws and the nearest magnetic ball is fixed, and the magnetic attraction force or the magnetic repulsion force is maximized and evenly distributed.

Fig. 1B is a perspective view of a substrate transportation apparatus according to a second embodiment of the invention, wherein the same or similar reference numerals are used to refer to the same or similar components as those in the first embodiment, and the materials, dimensions and functions thereof are described in detail in the above embodiments, and thus are not repeated herein.

Referring to fig. 1B, the second embodiment differs from the first embodiment in that the second screw is replaced with a magnet piece formed of a plurality of magnet bars 120, which is also disposed with respect to the first screw 110 such that the transport path 116 of the substrate 114 is located between the first screw 110 and the magnet piece. In another embodiment, the magnet piece may be a one-piece magnet piece instead of the divided magnet bars 120.

Fig. 1C is a perspective view of a substrate transportation apparatus according to a third embodiment of the invention, wherein the same or similar reference numerals are used to refer to the same or similar components as those in the first embodiment, and the materials, dimensions and functions thereof are described in detail in the above embodiments, and thus are not repeated herein.

Referring to fig. 1C, the difference between the third embodiment and the first embodiment is that the first and second screws are changed into a first screw 122 and a second screw 124 extending along the direction of the conveying path 116, the position of the first screw 122 is opposite to the position of the second screw 124, so that the conveying path 116 of the substrate 114 is located between the first screw 122 and the second screw 124, and the positions of the first and

second screws

122, 124 are slightly downward and close to the lower part of the substrate 114, so as to stabilize the lower part of the vertically conveyed substrate 114. The position and size of the magnetic ball 106 within the first and

second screws

122, 124 will be described in detail below.

On the other hand, the second screw 124 in the third embodiment may be replaced with the plurality of magnet bars 120 in the second embodiment so as to be disposed in an asymmetric configuration with respect to the first screw 122, and so that the transport path 116 of the substrate 114 is located between the first screw 122 and the magnet pieces (not shown). Further, a plurality of magnet bars may be replaced with a single magnet piece.

Fig. 2 and 3 are partially enlarged views of two kinds of first screws (second screws) in the third embodiment, respectively.

In fig. 2, the magnetic balls 106 are aligned along the thread of each first screw 122 and along the thread of each second screw 124, respectively. The magnetic ball 106 is a convex portion 200a provided on the screw of the first screw 122 and a convex portion 200b provided on the screw of the second screw 124. When the first screw 122 is driven by the actuator (not shown) to rotate clockwise and the second screw 124 is driven by the actuator (not shown) to rotate counterclockwise, the magnetic balls 106 disposed in the first screw 122 and the magnetic balls 106 disposed in the second screw 124 periodically approach each other to generate a magnetic attraction force or a magnetic repulsion force, thereby stabilizing the substrate 114 during the transfer.

In fig. 3, the magnetic balls 106 are also aligned along the threads of each first screw 122 and along the threads of each second screw 124, respectively. However, the magnetic balls 106 are provided in the recessed portion 202a of the screw of the first screw 122 and the recessed portion 202b of the screw of the second screw 124. When the first screw 122 is driven by the actuator (not shown) to rotate clockwise and the second screw 124 is driven by the actuator (not shown) to rotate counterclockwise, the magnetic balls 106 disposed in the first screw 122 and the magnetic balls 106 disposed in the second screw 124 periodically approach each other to generate a magnetic attraction force or a magnetic repulsion force, thereby stabilizing the substrate 114 during the transfer.

In fig. 4, the magnetic ball 106 of fig. 2 is illustrated as being disposed on the convex portion 200a of the thread of the first screw 122, wherein the first screw 122 has a plurality of openings 300 distributed along the thread, and each magnetic ball 106 is disposed in each opening 300. In one embodiment, the width w of the opening 302 of the aperture 300 is less than the diameter d3 of the magnetic ball 106; and the inner diameter d4 of the bore 300 is greater than the diameter d3 of the magnetic ball 106. Thus, the magnetic ball 106 is free to roll in the bore 300.

Similarly, the second screw 124 may have a plurality of openings distributed along the thread, and each of the magnetic balls 106 may be disposed in each of the openings with the size of the opening being related to the size of the magnetic ball 106 as described above so that the magnetic ball 106 can freely roll in the opening.

The size relationship between the magnetic ball 106 and the opening 300 of fig. 4 can be applied to the first screw 110 and the second screw 112 in the previous embodiment.

In summary, the present invention utilizes the magnetic attraction force or magnetic repulsion force between the magnetic balls disposed in the screw to affect the magnetically attractable material structure in the substrate (such as a printed circuit board), so that the vertically transported substrate can be stably maintained at the middle of the transportation path.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
