[0030] Please refer to Figures 1 to 12 as shown, which is an embodiment of the present utility model. As Figure 1 shown, this embodiment discloses a loading port 100, which can be used to pick and place substrates within a box 200. Among them, the box 200 includes a receiving box 201 and a door cover 202 that is detachably locked to the front edge of the receiving box 201, and the box 200 is illustrated as a front opening unified pod (FOUP) in this embodiment, but the present utility model is not limited thereto. For example, in other embodiments not shown in the present utility model, the box 200 can also adopt a structure different from the front opening unified pod according to actual needs.

[0031] In this embodiment, the loading port 100 includes a workbench 1, a conveying device 2 installed on the front side of the workbench 1, and a door opening / closing device 3 installed on the rear side of the workbench 1. Among them, the workbench 1 includes a carrier 11 and a frame 12 perpendicular to the carrier 11, and the carrier 11 corresponds to the lower half of the frame 12, and the frame 12 has an entrance / exit 121 located above the carrier 11.

[0032] More specifically, to ensure that the loading port 100 can stably hold the box body 200 during operation, the workbench 1 may optionally include a top buckling mechanism 13 and two anti-tipping members 14. Among them, the top buckling mechanism 13 is rotatably installed on the frame body 12 and is located above the entrance 121, and the two anti-tipping members 14 are fixed to the frame body 12 and are located on opposite sides of the entrance 121.

[0033] In this embodiment, the top buckling mechanism 13 includes a top buckling driver 131 and a clamping arm 132 linked to the top buckling driver 131. The clamping arm 132 is L-shaped and can be driven by the top buckling driver 131 to move and rotate outwards, so that the top buckling mechanism 13 (such as the clamping arm 132) can buckle on the top edge of the receiving box 201 (such as Figure 7 shown). Furthermore, the two anti-tipping members 14 are exemplified by two guiding blocks and can be embedded in the two side edges of the receiving box 201.

[0034] As Figures 1 to 4 shown, the conveying device 2 is arranged corresponding to the carrier 11, and the conveying device 2 is used to receive the box body 200 transmitted from a transport vehicle 300. Among them, the conveying device 2 includes a receiving mechanism 21 installed on the carrier 11, a box body lifting mechanism 22 arranged corresponding to the receiving mechanism 21, and a transfer mechanism 23 installed on the carrier 11 and linked to the box body lifting mechanism 22, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the receiving mechanism 21 of the conveying device 2 may be omitted or replaced by other components according to actual needs.

[0035] In this embodiment, the receiving mechanism 21 has a plurality of rollers 211, a plurality of transmission gears 212 respectively connected to the plurality of rollers 211, a plurality of idler gears 213 respectively meshing with the plurality of transmission gears 212, a linkage rod 214, and a roller motor 215 linked to the linkage rod 214, but the present invention is not limited thereto. That is to say, the specific configuration of the receiving mechanism 21 can be adjusted and changed according to actual needs.

[0036] More specifically, a plurality of the rollers 211 are respectively located on opposite sides of the carrier 11 to receive the box body 200 transmitted from the carrier vehicle 300. A plurality of the transmission gears 212 are respectively located on opposite sides of the carrier 11 and outside the plurality of rollers 211; that is, each transmission gear 212 can rotate synchronously with one of the rollers 211 connected thereto. An idle gear 213 is engaged between any two adjacent transmission gears 212 to enable the plurality of transmission gears 212 and the plurality of rollers 211 to rotate in the same direction.

[0037] Furthermore, the linkage rod 214 is connected to two of the transmission gears 212 respectively located on opposite sides of the carrier 11, and the roller motor 215 and the linkage rod 214 can drive the plurality of transmission gears 212 and the plurality of idle gears 213 to rotate synchronously, so that the plurality of rollers 211 are used to move the box body 200. That is to say, the receiving mechanism 21 can be driven by a single roller motor 215 through the cooperation of the above components, thereby simplifying the overall structure, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the receiving mechanism 21 may also use two roller motors 215 according to actual needs, which respectively drive two of the transmission gears 212 located on opposite sides of the carrier 11.

[0038] The box body lifting mechanism 22 is generally located below the plurality of rollers 211, and the plurality of rollers 211 are respectively located on opposite sides of the box body lifting mechanism 22. Among them, the box body lifting mechanism 22 can lift the box body 200 in a height direction H so that the box body 200 is separated from the receiving mechanism 21 or the plurality of rollers 211 (such as: Figure 6 shown). In this embodiment, the box body lifting mechanism 22 includes a carrier plate 221 and a box body driving module 222 connected to the carrier plate 221, and the box body driving module 222 can drive the carrier plate 221 to lift in the height direction H so that the carrier plate 221 can be raised to a position higher than the plurality of rollers 211, and then used to carry the box body 200.

[0039] Further, the box body driving module 222 in this embodiment includes a carrier plate lifting motor 2221 and a carrier plate linkage assembly 2222 connecting the carrier plate lifting motor 2221 and the carrier plate 221 (such as: a speed reducer and a plurality of lifting rods). Thus, the carrier plate lifting motor 2221 can drive the carrier plate linkage assembly 2222 to drive the carrier plate 221 to lift in the height direction H.

[0040] Furthermore, the transfer mechanism 23 is linked to the box driving module 222 (for example: the transfer mechanism 23 is fixed to the stage 11 and connected to the carrier plate linkage assembly 2222), so as to be able to drive the box lifting mechanism 22 to reciprocate relative to the stage 11 along a transfer direction D perpendicular to the height direction H (for example: Figure 7 and Figure 8 as shown).

[0041] It should be added that, in order to enable the carrier plate 221 to accurately position the box 200, the conveying device 2 may optionally include a clamping mechanism 24, a plurality of positioning posts 25, a plurality of air nozzles 26, and a plurality of detectors 27. In this embodiment, the clamping mechanism 24 includes two clamping plates 241 arranged at intervals and capable of rotating in opposite directions respectively, and a driver 242 for driving the two clamping plates 241 to operate. And the clamping mechanism 24, the plurality of positioning posts 25, the plurality of air nozzles 26, and the plurality of detectors 27 are all installed on the carrier plate 221 and at least some of them can be selected and installed on the carrier plate 221 according to actual needs.

[0042] Thus, as Figure 6 shown, when the box 200 is set on the carrier plate 221 (or when the carrier plate 221 is raised to carry the box 200), the clamping mechanism 24 can use the two clamping plates 241 to hold the bottom edge of the storage box 201, the plurality of positioning posts 25 are used to insert and position the bottom edge of the storage box 201, the plurality of air nozzles 26 are used to connect to the bottom edge of the storage box 201 and can replace the gas inside the box 200, and the plurality of detectors 27 are used to detect whether the bottom edge of the storage box 201 is on the carrier plate 221.

[0043] As Figure 1 and Figure 5 shown, the door opening and closing device 3 includes a door opening and closing mechanism 31 and a door cover lifting mechanism 32 linked to the door opening and closing mechanism 31. Among them, the door opening and closing mechanism 31 and the door cover lifting mechanism 32 are both installed on the frame 12, and the door opening and closing mechanism 31 is located at an operating position covering the entrance 121 (for example: Figure 1 and Figure 5 shown), and the door cover lifting mechanism 32 can drive the door opening and closing mechanism 31 to leave the entrance 121 from the operating position and descend to an avoidance position lower than the stage 11 (for example: Figure 8 and Figure 9 shown).

[0044] More specifically, the door opening and closing mechanism 31 includes a plate body 311, a plurality of rotary keys 312 protruding from the plate body 311, at least one driver 313 for linking the plurality of rotary keys 312, and a plurality of suction cups 314 provided on the plate body 311. Among them, the plurality of rotary keys 312 and the plurality of suction cups 314 are both located on the front side of the plate body 311, and the plurality of suction cups 314 are arranged outside the plurality of rotary keys 312, while at least one driver 313 is located inside the plate body 311 or on the rear side of the plate body 311 and can drive the plurality of rotary keys 312 to rotate.

[0045] Furthermore, the door cover lifting mechanism 32 includes a plate body lifting motor 321 and a plate body linkage assembly 322 (such as a belt, a connecting rod, and a plurality of linear slide rails) connecting the plate body lifting motor 321 and the plate body 311. Thus, the plate body lifting motor 321 can drive the plate body linkage assembly 322 to drive the plate body 311 to lift and lower along the height direction H.

[0046] As described above, as Figure 5 and Figure 7 shown, when the conveying device 2 jacks up the box body 200 through the box body lifting mechanism 22 and the transfer mechanism 23 and abuts the door cover 202 against the plate body 311, the two anti-tipping members 14 are embedded in the two side edges of the receiving box 201, and the top buckling mechanism 13 can buckle on the top edge of the receiving box 201 to ensure the relative position between the receiving box 201 and the frame body 12. Then, the plurality of suction cups 314 adsorb the door cover 202, and the plurality of rotary keys 312 can be inserted and positioned on the door cover 202 and rotated to unlock the door cover 202 from the receiving box 201, so that the transfer mechanism 23 can move the receiving box 201 away from the plate body 311 (such as Figure 4 and Figure 8 shown), so that the receiving box 201 is separated from the door cover 202.

[0047] Thus, in this embodiment, the loading port 100 can actively drive the box body 200 to move to open the cover through the cooperation of the conveying device 2 and the door opening and closing device 3 (such as the transfer mechanism 23 cooperating with the door opening and closing mechanism 31), which helps to simplify the overall structure of the loading port 100, facilitate maintenance and installation, and reduce the overall volume of the loading port 100.

[0048] In addition, the following content then describes the related operations of the loading port 100 after the receiving box 201 is separated from the door cover 202, but the present invention is not limited thereto. As Figure 4 and Figure 8As shown, when the receiving box 201 is separated from the door cover 202, the transfer mechanism 23 can move the receiving box 201 away from the entrance 121, and the door cover lifting mechanism 32 can drive the door opening and closing mechanism 31 and the door cover 202 to move to the avoidance position, and then the transfer mechanism 23 can move the receiving box 201 toward the entrance 121 (e.g.: Figure 4 and Figure 9 As shown), the loading port 100 can perform a substrate placement operation on the containing box 201 through the entrance 121.

[0049] Furthermore, if Figure 4 and Figure 10 As shown, when the loading port 100 completes the substrate placement operation of the container box 201, the transfer mechanism 23 can move the container box 201 away from the entrance 121, and the door cover lifting mechanism 32 can drive the door opening and closing mechanism 31 and the door cover 202 to move to the operating position. Figure 4 , Figure 5 and Figure 11 As shown, when the door opening and closing mechanism 31 and the door cover 202 move to the working position, the transfer mechanism 23 can move the storage box 201 to the door cover 202, so that the two anti-dumping parts 14 are embedded in the two side edges of the storage box 201, and the top buckle mechanism 13 can be buckled on the top edge of the storage box 201, so that the plurality of rotary keys 312 can be rotated to lock the door cover 202 to the storage box 201.

[0050] Finally, if Figure 4 and Figure 12 As shown, the loading port 100 can use the transfer mechanism 23 to move the containing box 201 away from the entrance 121, and use the box lifting mechanism 22 to drive the box 200 down to the receiving mechanism 21 (such as: multiple rollers 211) to allow the transport vehicle 300 to transport the box 200 that has completed the substrate placement operation.

[0051] [Technical effects of the utility model embodiment]

[0052] In summary, the loading port disclosed in the embodiment of the utility model can actively drive the box to move to open the cover through the combination of the conveying device and the door opening and closing device (such as: the transfer mechanism is combined with the door opening and closing mechanism), thereby helping to simplify the overall structure of the loading port, facilitate maintenance and installation, and reduce the overall volume of the loading port.

[0053] The content disclosed above is only an optional and feasible embodiment of the present utility model, and does not limit the patent scope of the present utility model.
