[0031] [Embodiment]

[0032] Please refer to Figure 1-8 , the present utility model provides a jaw mechanism, which can be applied to the handling device of an automated guided vehicle for transporting a carrier 100. The carrier 100 can be a wafer cassette (FOUP) or a cartridge, etc. The handling device may include a base 1, a transverse movement mechanism 2, a lifting mechanism 3 and a jaw mechanism 4.

[0033] The base 1 has a top plate 11, and the top plate 11 can be a square plate. The transverse movement mechanism 2 is disposed on the top plate 11 of the base 1. The transverse movement mechanism 2 is disposed below the base 1, the lifting mechanism 3 is disposed below the transverse movement mechanism 2, and the jaw mechanism 4 is disposed below the lifting mechanism 3, so that the base 1, the transverse movement mechanism 2, the lifting mechanism 3 and the jaw mechanism 4 are arranged in sequence from top to bottom. The lifting mechanism 3 is connected between the transverse movement mechanism 2 and the jaw mechanism 4. The jaw mechanism 4 can be used to clamp the carrier 100, and the carrier 100 is driven by the transverse movement mechanism 2 to traverse along a transverse movement direction A perpendicular to the guiding track 50, and the carrier 100 can be driven by the lifting mechanism 3 to move up and down, so that the carrier 100 can be transported to a predetermined position.

[0034] Please refer to Figures 3 to 5 , the jaw mechanism 4 includes a jaw power group and two jaws 43. The jaw power group includes a driving motor 41 and a transmission belt group 42. The driving motor 41, the transmission belt group 42 and the jaws 43 are disposed in a lower housing 44. The driving motor 41 and the transmission belt group 42 can be disposed inside the lower housing 44, which can prevent dust or oil generated during the operation of the jaw power group (the driving motor 41 and the transmission belt group 42) from falling downward and contaminating the carrier 100. The two jaws 43 can be disposed outside the lower housing 44, and the two jaws 43 can expose the bottom side of the lower housing 44 to clamp the carrier 100.

[0035] The transmission belt group 42 is connected between the driving motor 41 and the two jaws 43, so that the two jaws 43 are connected to the jaw power group. The two jaws 43 are long clamping members, and the two jaws 43 can be L-shaped plates. The structure of the jaws 43 is not limited and can change corresponding to the type of the carrier 100. The driving motor 41 can drive the two jaws 43 through the transmission belt group 42, so that the two jaws 43 approach or separate from each other, and can clamp or release the carrier 100.

[0036] In this embodiment, at least one guiding track 50 (such as Figure 7 shown) can be provided on the lower housing 44. Each of the two jaws 43 is connected to at least one guiding slider 51. The guiding slider 51 is slidably engaged with the guiding track 50. The guiding slider 51 can be used to guide the two jaws 43 to approach or separate from each other by sliding on the guiding track 50, so that the movement of the two jaws 43 is stable and smooth. Preferably, two guiding tracks 50 are provided, and the two guiding tracks 50 are arranged parallel to each other and at intervals. The guiding sliders 51 are respectively slidably engaged with the two guiding tracks 50.

[0037] In this embodiment, a contrast sensor 45 may be further disposed at intervals at both ends of the two jaws 43 on the bottom side of the lower housing 44, which can be used to detect whether the jaw mechanism 4 is placed in the carrier 100. The contrast sensor 45 can also be replaced by other types of sensors.

[0038] In this embodiment, the jaw mechanism 4 may further include a braking device 46, and the braking device 46 is connected to the transmission belt group 42 to provide a braking function. Preferably, the driving motor 41 and the braking device 46 are respectively disposed at both ends of the transmission belt group 42, which can reduce the occupied height space.

[0039] In this embodiment, a guiding structure is provided between the jaw mechanism 4 and the lifting mechanism 3. The guiding structure may include a plurality of guiding columns 47 and a plurality of guiding seats 36 (as Figure 8 shown). Each of the guiding seats 36 is provided with a guiding hole 361. The guiding columns 47 and the guiding seats 36 can be disposed on the jaw mechanism 4 or the lifting mechanism 3. When the jaw mechanism 4 ascends, the guiding columns 47 can be respectively inserted into the corresponding guiding holes 361 to provide a guiding and positioning effect, so that the jaw mechanism 4 is accurately positioned. Preferably, one end of each of the guiding columns 47 can be conical or arc-shaped, and a tapered hole 362 is provided at one end of each of the guiding holes 361, which can provide a better guiding and positioning effect.

[0040] The jaw mechanism 4 may further include a plurality of horizontal adjustment mechanisms 48. The horizontal adjustment mechanisms 48 are disposed on the lower housing 44 near the edge or at the corner, and can have a better horizontal adjustment effect. In this embodiment, the horizontal adjustment mechanism 48 includes a belt connecting member 481, a first seat body 482, a first axis 483, a second seat body 484, a second axis 485, a horizontal sensor 486 (as Figure 6 and Figure 7 shown) and an adjustment screw 487. The belt connecting member 481 is connected to one end (the lower end) of the lifting belt of the lifting mechanism 3. The first seat body 482 is connected to the belt connecting member 481 with the first axis 483. The second seat body 484 is connected to the first seat body 482 with the second axis 485. The first axis 483 and the second axis 485 are horizontally disposed and perpendicular to each other. The first axis 483 and the second axis 485 can be hinge pins, etc., mainly serving as fixing axes. The second seat body 484 is fixed to a fixing seat 488 on the lower housing 44. The adjustment screw 487 passes through the second seat body 484 and is screwed to the fixing seat 488. When the adjustment screw 487 rotates, the jaw mechanism 4 can be driven to move horizontally to adjust the levelness. In addition, a horizontal sensor 486 can be disposed on the second seat body 484 to detect the levelness.

[0041] The clamping jaw mechanism 4 may further include an elastic pressing mechanism 49 (such as Figure 5 shown), which can elastically press on the top of the carrier 100. In this embodiment, the elastic pressing mechanism 49 includes a pressing member 491, a linkage rod 492, a lifting fixed seat 493 and an elastic member 494. The pressing member 491 is connected to the lower end of the linkage rod 492. The lifting fixed seat 493 is fixed to the lower housing 44. The linkage rod 492 is arranged on the lifting fixed seat 493 in a liftable manner. The elastic member 494 abuts against the linkage rod 492. The elastic member 494 can push the linkage rod 492 and the pressing member 491 to move downward, so that the pressing member 491 elastically presses on the carrier 100, and the carrier 100 is stably positioned.

[0042] The clamping jaw mechanism of the utility model has a simplified structure, which can reduce costs, reduce failures, and is simple and convenient to maintain.

[0043] The above embodiments are the preferred implementation schemes of the utility model. In addition, the utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the utility model.
