Detailed Description

The following describes an embodiment of the present invention with reference to fig. 1 to 8. The description is not intended to limit the embodiments of the present invention, but is one example of the embodiments of the present invention.

As shown in fig. 1 to 5, a substrate holding device 1 of a substrate transport apparatus according to an embodiment of the present invention is provided in the substrate transport apparatus. The substrate conveying apparatus has a conveying member 2 moving along a conveying path P, a plurality of carrying frames 3 are arranged on the conveying member 2, and each of the plurality of carrying frames 3 has a substrate carrying space S for carrying a substrate B to convey the substrate B along with the movement of the conveying member 2.

As shown in fig. 1 to 5, in an embodiment of the present invention, the substrate supporting apparatus 1 includes: a plurality of support members 11 and guide members 12.

As shown in fig. 1 to 5, in the substrate supporting device 1 according to the embodiment of the present invention, a plurality of the supporting members 11 are arranged on the conveying member 2 in a manner corresponding to a plurality of the supporting frames 3, respectively, and move along with the conveying member 2, each of the supporting members 11 is configured to be displaced between a supporting position (shown in fig. 5) in which the supporting member 111 of the supporting member 11 is displaced to support the substrate B in the substrate supporting space S of the corresponding supporting frame 3 and a releasing position (shown in fig. 4) in which the supporting member 111 of the supporting member 11 is displaced to release the supporting of the substrate B.

As shown in fig. 1 to 5, in the substrate supporting device 1 according to the embodiment of the present invention, the guiding member 12 is fixedly disposed corresponding to the predetermined supporting state switching region E on the conveying path P, the guiding member 12 has a guiding track structure 121, and the guiding track structure 121 is configured to make the supporting member 11 move from the releasing position to the supporting position or from the supporting position to the releasing position when the supporting member 11 enters the supporting state switching region E through the movement of the conveying member 2 and the guidance of the guiding track structure 121.

Specifically, as shown in fig. 3 to 5, according to the substrate supporting apparatus 1 of the embodiment of the present invention, the supporting member 11 includes a displacement member 112 and a reset member 113, the supporting member 111 is located on the displacement member 112, and the reset member 113 is connected to the displacement member 112 in a manner that the displacement member 112 is normally biased toward the release position (fig. 4), so that when the supporting member 11 is not in the supporting state switching region E, the displacement member 111 is shifted from the supporting position (fig. 5) to the release position (fig. 4) by the reset member 113.

In the present embodiment, the restoring member 113 is a spring, more specifically, a compression spring. One end of the compression spring abuts against the base part 110 of the holding member 11, and the other end abuts against the inner end (lower end in the figure) of the displacement member 112, and the holding member 111 is disposed at the outer end (upper end in the figure) of the displacement member 112. Accordingly, the spring force of the compression spring pushes the displacement member 112 downward in the drawing, so that the displacement member 112 moves downward in a normal state where the displacement member is not biased by a force other than the compression spring, and the holder 111 also moves to the release position where the substrate is not held as the displacement member 112 moves downward (fig. 4). Of course, the present invention is not limited thereto. The reset member 113 may be disposed to achieve the reset effect by other means (e.g., gravity). The return member 113 may be replaced with a mechanism other than a spring (e.g., a pull cord).

As shown in fig. 3 to 5, according to the substrate holding device 1 of the embodiment of the present invention, the holding member 11 is configured to: in the holding position (fig. 5), the holder 111 of the holding member 11 is displaced into the corresponding substrate holding space S of the holding frame 3 to hold the substrate B, and in the release position (fig. 4), the holder 111 of the holding member 11 is displaced out of the substrate holding space S to release the holding of the substrate B.

Specifically, in the present embodiment, in order to avoid the interference of the support 111 with other components or substrates in the substrate supporting space S, the support 111 is withdrawn from the substrate supporting space S in the release position. Of course, the present invention is not limited thereto, and the support 111 may just leave the substrate B without exiting the substrate carrying space S for other reasons.

As shown in fig. 3 to 5, according to the substrate supporting device 1 of the embodiment of the present invention, the supporting member 111 is a stopper, and the supporting member 11 is configured to: in the holding position (fig. 5), the holding member 111 is displaced so as to be spaced apart from the carrier frame 3 by a predetermined holding interval D in the direction of the conveying path P, and holds the substrate B in such a manner that the end portion of the substrate B is held in the holding interval D.

Specifically, in the present embodiment, the support 111 does not directly clamp the substrate B, and the support 111 is used for blocking the end of the substrate B to prevent the substrate B from greatly sliding in the direction of the conveying path P, so as to prevent the substrate B from slipping off the carrying frame 3.

As shown in fig. 3, according to the substrate supporting device 1 of the embodiment of the present invention, the supporting state switching area E is set to correspond to the gradient change area on the conveying path P of the substrate conveying apparatus.

Specifically, in the present embodiment, the substrate supporting apparatus 1 is mainly used to prevent the substrate B from slipping off the supporting frame 3. Since the carrying frame 3 and the substrate B on the conveying path P are rotated in addition to the original translational motion when being conveyed through a region where the gradient changes (i.e., a gradient change region), the slipping-off of the substrate is likely to occur in this region. By disposing the guide members 12 correspondingly to the slope varying regions, the slipping-off of the substrate B can be effectively reduced or suppressed.

Fig. 6 to 8 show a substrate supporting apparatus 1a according to another embodiment of the present invention, wherein the same or corresponding components are designated by the same reference numerals.

As shown in fig. 6 to 8, according to a substrate supporting device 1a of another embodiment of the present invention, the supporting member 11 includes a displacement member 112 and a reset member 113, the supporting member 111 is located on the displacement member 112, and the reset member 113 is connected to the displacement member 112 in a manner that the displacement member 112 is normally biased toward the supporting position (fig. 7), so that when the supporting member 11 is not in the supporting state switching region E, the displacement member 112 is shifted from the releasing position (fig. 8) to the supporting position (fig. 7) by the reset member 113.

In the present embodiment, the displacement member 112 is a linkage, and the restoring member 113 is a spring, more specifically a compression spring. One end of the compression spring abuts against the base element 110 of the holding member 11, and the other end abuts against the inner end (upper end in the figure) of the displacement element 112, so that the upright rod 112a of the linkage is biased upward in a normal state without being biased by a force other than the compression spring, and the push rod 112d of the linkage is pushed laterally by the action of the links 112b and 112c, so that the holding element 111 disposed on the push rod 112d is displaced to approach the corresponding clamping part 110a on the base element 110 for clamping. Of course, the present invention is not limited thereto. The reset member 113 may be disposed to achieve the reset effect by other means (e.g., gravity). The return member 113 may be replaced with a mechanism other than a spring (e.g., a pull cord).

As shown in fig. 6 to 8, according to the substrate supporting device 1a of another embodiment of the present invention, the supporting member 111 is a jig, and the supporting member 11 is configured to: in the holding position (fig. 7), the holder 111 is displaced to clamp the holding opening C of the holder member 11, and holds the substrate B so as to hold the end portion of the substrate B.

Specifically, in the present embodiment, the holder 111 directly holds the substrate B, and the holder 111 is capable of holding the substrate B so that the substrate B does not fall off even when being conveyed below the conveying member 2.

As shown in fig. 6 to 8, according to the substrate supporting device 1a of another embodiment of the present invention, the supporting state switching area E is set to correspond to the substrate lead-in area E1 and/or the substrate lead-out area E2 on the conveying path P of the substrate conveying apparatus.

Specifically, in the present embodiment, the substrate holding device 1a is mainly used to prevent the substrate B from falling off the carriage frame 3 in the entire course of the conveying path P, so it is desirable that the substrate holding device 1a continuously holds the substrate B except for the substrate introduction area E1 where the substrate B is introduced into the substrate conveying apparatus and the substrate lead-out area E2 where the substrate B is led out from the substrate conveying apparatus, and therefore, only the guide members 12 are provided correspondingly to the substrate introduction area E1 and the substrate lead-out area E2.

As shown in fig. 1, 3 and 6, according to the substrate supporting apparatus 1, 1a of the embodiment of the present invention, the conveying member 2 is an annular conveying member, a plurality of the supporting frames 3 are arranged outside the annular conveying member, and the guiding member 12 is fixedly disposed inside the annular conveying member. With this structure, the guide member 12 can be disposed without occupying an additional space, effectively avoiding the increase in volume of the substrate transport apparatus.

As shown in fig. 1 and 3 to 8, the guiding member 12 is a fixed cam, and the guiding track structure 121 is a cam surface of the fixed cam, which is configured to push against an inner end of the supporting member 11 in a lift-forming manner when the supporting member 11 enters the supporting state switching region E along with the conveying member 2, so as to lift (i.e., lift and move relative to the guiding member 12) the supporting member 11 to the supporting position (fig. 5) or the releasing position (fig. 8). Of course, the present invention is not limited thereto, the guiding member 12 can be other members, and the guiding track structure 121 can also be other structures, for example, the guiding track structure 121 can be a concave track formed on the fixed cam.

Through the structure, the utility model discloses a base plate holds bearing device 1, 1a can hold this base plate B on this transfer path P to reduce effectively or restrain slippage, collision, and the damage of this base plate B in transportation process. Further, the substrate holding device can hold the substrate B in a specific holding state switching region E on the transport path P according to different designs, and does not hold the substrate B in a region other than the holding state switching region E (the substrate holding device 1 shown in fig. 3 to 5), or holds the substrate B in a normal state on the transport path P, and releases the holding of the substrate B only in the holding state switching region E (the substrate holding device 1a shown in fig. 6 to 8). In the preferred embodiment, the substrate holding device can hold the substrate in various manners such as a limit position (the substrate holding device 1 shown in fig. 3 to 5) and a clamp position (the substrate holding device 1a shown in fig. 6 to 8) according to various types of transport.

The above description and illustrations are only for the description of the preferred embodiments of the present invention, and other modifications may be made by those skilled in the art within the scope of the claims and the description above, and these modifications are still intended to be within the spirit of the present invention.
