DETAILED DESCRIPTION

[0026] The following is based on Figures 1 to 8 , illustrating the implementation of the present invention. This description is not intended to limit the implementation of the present invention, but is one of the embodiments of the present invention.

[0027] like Figures 1 to 5 As shown, a substrate holding device 1 of a substrate conveying device according to an embodiment of the present invention is arranged on the substrate conveying device. The substrate conveying device has a conveying member 2, which moves 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, so as to convey the substrate B as the conveying member 2 moves.

[0028] like Figures 1 to 5 As shown, in an embodiment of the present invention, the substrate holding device 1 comprises: a plurality of holding members 11 and a guiding member 12 .

[0029] like Figures 1 to 5 As shown, in the substrate holding device 1 of the embodiment of the present invention, a plurality of the holding members 11 are arranged on the conveying member 2 in a manner corresponding to the plurality of the carrying frames 3 respectively, and as the conveying member 2 moves, each of the holding members 11 is arranged at a holding position (such as Figure 5 as shown) and the release position (as shown Figure 4 As shown), wherein in the holding position, the holding member 111 of the holding member 11 is displaced to hold the substrate B in the substrate holding space S of the corresponding supporting frame 3, and in the releasing position, the holding member 111 of the holding member 11 releases the holding of the substrate B by displacement.

[0030] like Figures 1 to 5As shown, in the substrate holding device 1 of an embodiment of the present invention, the guiding member 12 is fixedly arranged corresponding to the preset holding state switching area E on the conveying path P, and the guiding member 12 has a guiding track structure 121, and the guiding track structure 121 is arranged to enable the holding member 11 to move from the release position to the holding position, or from the holding position to the release position when the holding member 11 enters the holding state switching area E by moving with the conveying member 2 and being guided by the guiding track structure 121.

[0031] Specifically, if Figures 3 to 5 As shown, according to the substrate holding device 1 of an embodiment of the present invention, the holding member 11 includes a displacement member 112 and a reset member 113. The holding member 111 is located on the displacement member 112. The reset member 113 is used to make the displacement member 112 move toward the release position ( Figure 4 ) is connected to the displacement member 112 in a biasing manner, so that when the holding member 11 is not in the holding state switching area E, the displacement member 111 is moved from the holding position ( Figure 5 ) moves to the release position ( Figure 4 ).

[0032] In the present embodiment, the reset member 113 is a spring, more specifically a compression spring. One end of the compression spring abuts against the base member 110 of the supporting member 11, and the other end abuts against the inner end (the lower end in the figure) of the displacement member 112, and the supporting member 111 is disposed at the outer end (the upper end in the figure) of the displacement member 112. As a result, the elastic force of the compression spring pushes the displacement member 112 downward in the figure, so that the displacement member 112 moves downward in a normal state when not subjected to any force other than the compression spring, and the supporting member 111 also moves downward with the displacement member 112, and moves to the release position ( Figure 4 Of course, the present invention is not limited thereto. The reset member 113 may not be provided, and other means (such as gravity) may be used to achieve the reset effect. The reset member 113 may also be replaced by a mechanism other than a spring (such as a pull rope).

[0033] like Figures 3 to 5 As shown, according to the substrate holding device 1 of the embodiment of the present invention, the holding member 11 is configured as follows: Figure 5 ), the holding member 111 of the holding member 11 is displaced into the substrate holding space S of the corresponding carrying frame 3 to hold the substrate B, and in the release position ( Figure 4 ), the holding member 111 of the holding component 11 is displaced away from the substrate carrying space S to release the holding of the substrate B.

[0034] Specifically, in this embodiment, in order to prevent the holding member 111 from interfering with other components or substrates in the substrate carrying space S, the holding member 111 will exit the substrate carrying space S when in the release position. Of course, the present invention is not limited thereto, and based on other considerations, the holding member 111 may also simply leave the substrate B without exiting the substrate carrying space S.

[0035] like Figures 3 to 5 As shown, according to the substrate holding device 1 of the embodiment of the present invention, the holding member 111 is a blocking rod, and the holding member 11 is configured to: at the holding position ( Figure 5 ), the holding member 111 is displaced to be separated from the supporting frame 3 by a predetermined holding interval D in the direction of the conveying path P, and the substrate B is held in such a manner that the end of the substrate B is limited in the holding interval D.

[0036] Specifically, in this embodiment, the holding member 111 does not directly clamp the substrate B. The function of the holding member 111 is to block the end of the substrate B to prevent the substrate B from sliding significantly in the direction of the conveying path P, thereby preventing the substrate B from slipping off the supporting frame 3.

[0037] like Figure 3 As shown, according to the substrate holding device 1 of an embodiment of the present invention, the holding state switching area E is set to correspond to the slope change area on the conveying path P of the substrate conveying equipment.

[0038] Specifically, in this embodiment, the substrate holding device 1 is mainly used to prevent the substrate B from slipping off the carrier frame 3. Since the carrier frame 3 and the substrate B on the conveying path P will undergo rotational motion in addition to the original translational motion when conveying through the area where the slope changes (i.e., the slope change area), the slipping of the substrate will mostly occur in this area. By arranging the guide member 12 in the slope change area, the slipping of the substrate B can be effectively reduced or suppressed.

[0039] Figures 6 to 8 A substrate holding device 1 a according to another embodiment of the present invention is shown, wherein the same or corresponding components are marked with the same component symbols.

[0040] like Figures 6 to 8 As shown, according to another embodiment of the substrate holding device 1a of the present invention, the holding member 11 includes a displacement member 112 and a reset member 113. The holding member 111 is located on the displacement member 112. The reset member 113 is used to make the displacement member 112 move toward the holding position ( Figure 7) is connected to the displacement member 112 in a biasing manner, so that when the holding member 11 is not in the holding state switching area E, the displacement member 112 is moved from the release position ( Figure 8 ) moves to the holding position ( Figure 7 ).

[0041] In this embodiment, the displacement member 112 is a connecting rod group, and the reset member 113 is a spring, more specifically a compression spring. One end of the compression spring abuts against the base member 110 of the support member 11, and the other end abuts against the inner end (upper end in the figure) of the displacement member 112, so that the vertical rod 112a of the connecting rod group will deflect upward in the normal state without being subjected to the force other than the compression spring, and through the action of the connecting rods 112b and 112c, the push rod 112d of the connecting rod group will be pushed laterally, so that the support member 111 set on the push rod 112d is displaced close to the clamping corresponding part 110a on the base member 110 for clamping. Of course, the present invention is not limited to this. The reset member 113 can be omitted, and other methods (such as gravity) can be used to achieve the reset effect. The reset member 113 can also be replaced by a mechanism other than a spring (such as a pull rope).

[0042] like Figures 6 to 8 As shown, according to another embodiment of the substrate holding device 1a of the present invention, the holding member 111 is a clamp, and the holding member 11 is configured to: at the holding position ( Figure 7 ), the holding member 111 is displaced to cause the clamping opening C of the holding member 11 to clamp and hold the substrate B by clamping the end of the substrate B.

[0043] Specifically, in the present embodiment, the holding member 111 holds the substrate B by directly clamping the substrate B. The function of the holding member 111 is to grasp the substrate B so that the substrate B will not fall even when it is transported to the bottom of the transport member 2.

[0044] like Figures 6 to 8 As shown, according to another embodiment of the substrate holding device 1a of the present invention, the holding state switching area E is set to correspond to the substrate import area E1 and / or the substrate export area E2 on the conveying path P of the substrate conveying equipment.

[0045] Specifically, in the present embodiment, the substrate holding device 1a is mainly used to prevent the substrate B from falling from the supporting frame 3 throughout the entire conveying path P. Therefore, in addition to introducing the substrate B into the substrate introduction area E1 of the substrate conveying equipment and exporting the substrate B from the substrate conveying equipment to the substrate export area E2, it is hoped that the substrate holding device 1a can continue to clamp the substrate B. Therefore, only the guiding member 12 is correspondingly arranged in the substrate introduction area E1 and the substrate export area E2.

[0046] like Figure 1 , Figure 3 and Figure 6 As shown, according to the substrate holding device 1, 1a of the embodiment of the present invention, the conveying member 2 is an annular conveying member, a plurality of the carrying frames 3 are arranged on the outside of the annular conveying member, and the guide member 12 is fixedly arranged on the inside of the annular conveying member. With this structure, the guide member 12 can be arranged without occupying additional space, effectively avoiding the increase in the volume of the substrate conveying device.

[0047] like Figure 1 , Figures 3 to 8 As shown, the guide member 12 is a fixed cam, and the guide track structure 121 is a cam surface of the fixed cam. The cam surface is configured to push against the inner end of the holding member 11 in a lifting manner when the holding member 11 enters the holding state switching area E along with the conveying member 2, so that the holding member 11 is lifted (i.e., lifted relative to the guide member 12) to the holding position ( Figure 5 ) or the release position ( Figure 8 Of course, the present invention is not limited thereto, the guide member 12 may be other members, and the guide track structure 121 may also be other structures. For example, the guide track structure 121 may be a concave track formed on the fixed cam.

[0048] Through the above structure, the substrate holding device 1, 1a of the present invention can hold the substrate B on the conveying path P to effectively reduce or inhibit the slipping, collision, and damage of the substrate B during the conveying process. Furthermore, the substrate holding device can hold the substrate B in a specific holding state switching area E on the conveying path P according to different designs, and not hold the substrate B in areas outside the holding state switching area E (such as Figures 3 to 5 The substrate holding device 1 shown in the figure, or the substrate B is normally held on the conveying path P, and the holding of the substrate B is released only in the holding state switching area E (such as Figures 6 to 8 Furthermore, in a preferred embodiment, the substrate holding device 1a can also be limited according to different types of transport (such as Figures 3 to 5The substrate holding device 1 shown in FIG. Figures 6 to 8 The substrate is held in various ways, such as the substrate holding device 1a) shown.

[0049] The above description and explanation are only the description of the preferred embodiments of the present invention. Those skilled in the art may make other modifications according to the scope defined by the claims and the above explanation, because these modifications should still be within the spirit of the present invention and within the scope of the present invention.
