Referring specifically to fig. 2, the feeding platform 2 positions the pod 200 after the pod 200 is placed in a precise position. The structure of the feeding platform 2 is as follows: comprises a bottom plate 21, a track 22, a first linear module 23, a first placing platform 24, a position detection sensor 25, a product information identification sensor 26 and a limiting mechanism 27. The bottom plate 21 is fixedly connected to a rack of the whole machine, the track 22 and the first linear module 23 are fixed on the bottom plate 21, the first placing platform 24 is slidably connected and supported on the track 22 and the first linear module 23, and the position detection sensor 25, the product information identification sensor 26 and the limiting mechanism 27 are arranged on the first placing platform 24. The first linear module 23 is connected with the first placing platform 24 so as to drive the first placing platform 24 to move, and the rail 22 gives the first placing platform 24 a supporting and guiding function at the other side relative to the first linear module 23. The bottom of the wafer box 200 is provided with a groove, and the limiting mechanism 27 extends into the groove at the bottom of the wafer box 200 and then rotates for positioning the wafer box 200 on the first placing platform 24. In this embodiment, three position detection sensors 25 are disposed around the limiting mechanism 27 and electrically connected to the electrical control center, and are used to detect whether the wafer cassette 200 is placed at a correct position; the product information recognition sensor 26 is disposed at one side of the limiting mechanism 27 and electrically connected to the electrical control center, and is configured to detect whether the wafer cassette 200 needs to be filled with nitrogen gas.

Referring to fig. 18 to 20, a first clamping mechanism 31 is disposed at a bottom end of the first transporting device 3 (in the embodiment, a robot), and a first supporting mechanism 171 is disposed at a bottom end of the second transporting device 17 (in the embodiment, a robot). The first clamping mechanism 31 is used for clamping the head of the wafer cassette 200 for clamping the wafer cassette 200, that is, the first transporting device 3 is used for transporting the wafer cassette 200 from the feeding platform 2 to the bag-in module 5 in a manner of clamping the head of the wafer cassette 200. The first bottom supporting mechanisms 171 are provided in two opposing left-right directions, that is, the second transfer device 17 transfers the wafer cassette 200 from the sealing module 8 or the shaping rotary table 10 to the discharge table 18 in such a manner as to support the main body of the wafer cassette 200 (similar to a case where one cassette is held with both hands).

In the first embodiment of the present invention, as shown in fig. 18, the first carrying device 3 and the second carrying device 17 share a set of supporting frame 201 and supporting rail 202; in the second embodiment of the present invention, which is not shown in the drawings, the first conveying device 3 and the second conveying device 17 may have the support frame 201 and the support rail 202 which are independent of each other. Referring to fig. 4 to 8, the bag taking device 6 picks up the bag on the bag storage box 4 to the packing platform 7, and the packing platform 7 and the bag taking device 6 together pull the upper and lower layers of the bag apart to form an opening.

The bag taking device 6 comprises a first gripping device 64 (a sucker connected with a vacuum system in the specific embodiment), the packaging platform 7 comprises a second gripping device 79 (a sucker connected with a vacuum system in the specific embodiment), the first gripping device 64 sucks the upper layer of the packaging bag, and the second gripping device 79 sucks the lower layer of the packaging bag to pull the upper layer and the lower layer of the packaging bag apart to form an opening.

The bag taking device 6 comprises a transverse unit 61, and the transverse unit 61 comprises a first driving member 611 (in the embodiment, a motor), a first pulley pair 612, a first belt 613, a first belt clamping plate 614, a first guide rail pair 615, a first sliding block 616, and a first moving frame 617. The first moving frame 617 is connected to the first belt 613 between the first pulley pair 612 through the first belt clamping plate 614, and the first driving member 611 drives the first pulley pair 612 so that the first belt 613 drives the first moving frame 617 to move in a first direction (in the specific embodiment, the first direction is a transverse direction in fig. 6). Because the first guide rail pair 615 is stationary, the first driving member 611 drives the first moving frame 617 to move in the first direction through the first pulley pair 612 and the first belt 613, and the first driving member 611 provides a driving force in the first direction, so that the first moving frame 617 can move in the first direction and is stationary in a direction different from the first direction. The first belt clamping plate 614 is fixedly connected to a first sliding block 616 that is slidably and limitedly disposed on the first rail pair 615. That is, the engagement between the first guide rail pair 615 and the first slider 616 limits the first direction movement of the first moving frame 617.

The bag taking device 6 includes a vertical unit 62, and the vertical unit 62 includes a second driving element 621 (in the embodiment, an air cylinder), a second pulley pair (not numbered), a second belt clamping plate (not numbered), a second guide rail pair 625, a second slider 626 and a lifting mechanism 627. The second slider 626 is connected to the first moving frame 617, the second guide rail pair 625 is connected to the lifting mechanism 627, and the second slider 626 slides on the second guide rail pair 625 in a limited manner. The lifting mechanism 627 is connected to the second belt between the second pair of pulleys through the second belt clamp plate, and the second driving member 621 drives the second pair of pulleys so that the second belt drives the lifting mechanism 627 to move in a second direction (in the specific embodiment, the second direction is the vertical direction in fig. 6) different from the first direction. The first driving member 611 drives the first moving frame 617 to move in the first direction, and the lifting mechanism 627 is disposed on the first moving frame 617 so as to be movable in the first direction together with the first moving frame 617; the second driving member 621 drives the lifting mechanism 627 to move in a second direction relative to the first moving frame 617, and the first grabbing device 64 is fixed to the lifting mechanism 627. That is, the first gripper device 64 on the bag-taking device 6 can move in both the first direction and the second direction. Because the second slider 626 is fixedly connected to the first moving frame 617, the second slider 626 is movable in the first direction but immovable in the second direction with the first moving frame 617; the second driving member 621 drives the lifting mechanism 627 to move in a second direction, which also drives the second guide rail pair 625 to move in a second direction relative to the second sliding block 626, i.e., relative to the first moving frame 617. The second driving element 621 provides a driving force in the second direction, and the cooperation between the second guide rail pair 625 and the second slider 626 limits the movement of the lifting mechanism 627 in the second direction.

Referring specifically to fig. 7 and 8, the packaging platform 7 includes a third driving member 71 (in the embodiment, a motor), a movable bottom plate 72, a packaging guide rail pair 74, a packaging screw pair 75, a supporting platform 76, a clamping plate mechanism 77, and an edge sealing and stripping mechanism 78. The third driving member 71 drives the movable bottom plate 72 to move in the first direction, the second grabbing device 79 is fixed on the movable bottom plate 72, and the first movable frame 617 is movably located above the movable bottom plate 72. The first moving frame 617 is horizontally movable in a first direction, on one hand, to a position of the pouch storage box to grasp the wafer box 200, and on the other hand, to a position above the moving bottom plate 72, so that the first grasping device 64 and the second grasping device 79 are located at opposite positions, that is, the first grasping device 64 is ensured to grasp an upper layer of the pouch while the second grasping device 79 is capable of grasping a lower layer of the pouch. The movable bottom plate 72 is in sliding fit with the packing guide rail pair 74, and the third driving member 71 is connected with the movable bottom plate 72 through the packing lead screw pair 75. The support platform 76 and the clamping mechanism 77 are fixed to the moving base plate 72. The chucking mechanisms 77 are located on both sides of the support platform 76 and can be brought close to each other to chuck and hold the wafer cassette 200 having the pocket in the position of the support platform 76. The supporting platform 76 is located on the movable bottom plate 72, and can move to the sealing module 8 along with the movable bottom plate 72 to seal the packaging bag with the box. The edge sealing and leveling mechanism 78 is fixed to the movable bottom plate 72, and the edge sealing and leveling mechanism 78 is capable of moving upward and is configured to push the edge seal of the packaging bag to move upward relative to the wafer box 200 after heat sealing is completed, so that the edge seal portion can be bent by 90 degrees to be attached to one side of the wafer box 200, and cannot extend straight forward to occupy the width of the wafer box 200 in the first direction, thereby facilitating the subsequent handling of the wafer box 200 into the bag by the third handling device 9.

In the specific tearing process, the first gripping device 64 faces downwards to suck the upper layer of the packaging bag, and after the second gripping device 79 faces upwards to suck the lower layer of the packaging bag, the second gripping device 79 is fixed and the first gripping device 64 moves upwards, namely, the bag taking device 6 cooperates with the packaging platform 7 to pull the upper layer and the lower layer of the packaging bag apart to form an opening. However, the suction force alone is not sufficient enough to hold the packaging bag, since the wafer box 200 is very likely to scratch the edge portion of the opening of the packaging bag when entering, so that the upper layer of the packaging bag is separated from the first gripping device 64 and/or the lower layer of the packaging bag is separated from the second gripping device 79. Therefore, it is necessary to position the upper layer of packages on the first gripper device 64 and the lower layer of packages on the second gripper device 79 by means of the components on the bag feeding module 5 to avoid scratching.

Referring to fig. 9 and 10, the bag-inserting module 5 includes a first frame 51, a supporting mechanism 52, and a bag-supporting mechanism 53. The bag opening mechanism 53 includes a bag opening frame 531, a forward/backward moving cylinder 532, an up/down opening cylinder 533, and a bag opening pressing plate 534. The first frame 51 is fixed on the whole machine frame, the bag opening frame 531 is fixed on the first frame 51, and the advancing and retreating cylinder 532, the up-down opening cylinder 533 and the bag opening pressing plate 534 are fixed on the bag opening frame 531. The bag stretching pressing plate 534 comprises an upper pressing plate 5341 and a lower pressing plate 5342 positioned below the upper pressing plate 5341, the forward and backward air cylinder 532 drives the upper pressing plate 5341 and the lower pressing plate 5342 to move in the same direction in a third direction (in the specific embodiment, the third direction is the transverse direction shown in fig. 10), that is, the forward and backward air cylinder 532 drives the upper pressing plate 5341 and the lower pressing plate 5342 in the same direction first, so that the upper pressing plate 5341 and the lower pressing plate 5342 extend into the openings torn by the first gripping device 64 and the second gripping device 79; next, the up-down opening cylinder 533 drives the upper pressing plate 5341 and the lower pressing plate 5342 to move away from each other in a second direction perpendicular to the third direction, that is, after the upper pressing plate 5341 and the lower pressing plate 5342 extend into the opening, the upper pressing plate 5341 positions the upper layer of the packaging bag upward on the first gripping device 64 and the lower pressing plate 5342 positions the lower layer of the packaging bag downward on the second gripping device 79.

The bag-in module 5 further includes a longitudinal moving guide rail pair 541, a first driving mechanism 542 (in the embodiment, a motor), a third pulley pair 543, and a first lead screw pair 544. The support mechanism 52 is slidably connected to the longitudinal movement rail pair 541 and connected to the nut of the first screw pair 544, and the first drive mechanism 542 drives the first screw pair 544 through the third pulley pair 543 to drive the support mechanism 52 to move along the longitudinal movement rail pair 541 in the third direction toward the bag opening mechanism 53, so that the wafer cassette 200 can be loaded into the packaging bag.

In the preferred embodiment of the present invention, since the wafer cassette 200 is labeled before the wafer cassette 200 is fed into the packaging bag, the bag feeding module 5 of the present invention further includes a labeling auxiliary mechanism 55. The auxiliary labeling mechanism 55 includes a conveying motor 551, two conveying lines 552 arranged in parallel driven by the conveying motor 551, and four gripper mechanisms 553. That is, the transfer line 552 extends in the third direction and transfers the wafer cassette 200. The clamping mechanisms 553 are distributed two by two on two outer sides of the extension direction of the conveying line 552, and include a first group of clamping mechanisms 5531 at the front end and a second group of clamping mechanisms 5532 at the rear end. The first set of grippers 5531 first grip the wafer cassette 200 to label the front of the wafer cassette 200, and then the conveyor line 552 transports the wafer cassette 200 to the position of the second set of grippers 5532, and the second set of grippers 5532 then grips the wafer cassette 200 to label the rear of the wafer cassette 200. After the label is applied, the wafer cassette 200 is transported to the end of the transport line 552 near the bag expanding mechanism 53. The invention is also provided with a blocking cylinder 57 and a first baffle plate 58 driven by the blocking cylinder 57, wherein the first baffle plate 58 extends upwards in the second direction to abut against the tail end of the conveying line 552, so as to prevent the wafer cassette 200 conveyed by the conveying line 552 from falling.

In the preferred embodiment of the present invention, the initial position of the support mechanism 52 is below the end of the delivery wire 552. The bag feeding module 5 of the present invention further includes an up-down moving rail pair 561, an up-down moving plate 562, a lifting plate 563, and a second driving mechanism 564 (in the specific embodiment, an air cylinder). The longitudinal moving guide rail pair 541 and the first lead screw pair 544 are fixed on the jacking plate 563, the middle of the jacking plate 563 is connected with the second driving mechanism 564, two ends of the jacking plate 563 are fixed on the up-down moving plate 562, and the up-down moving plate 562 is slidably connected on the up-down moving guide rail pair 561. Thus, when the wafer cassette 200 has been labeled to the end position of the transfer line 552, the second driving mechanism 564 can drive the lift plate 563 in the second direction to lift up the supporting mechanism 52 upward, so that the supporting mechanism 52 has a lifted position above the transfer line 552 where the supporting mechanism 52 is driven by the first driving mechanism 542 to feed the wafer cassette 200 into the packaging bag. Since the clamp mechanism 77 clamps the incoming cassette 200 at the position of the support platform 76, the force driving the support mechanism 52 is withdrawn so that the support mechanism 52 withdraws from the package, and then the support platform 76 moves the incoming cassette 200 with the movable bottom plate 72 to the sealing module 8 for the next evacuation heat-sealing operation.

Referring to fig. 11 and 12, the structure of the sealing module 8 is as follows: the device comprises a second frame 81, a second moving frame 82, a moving frame guide rail pair 821, a moving frame screw pair 822, an air exhaust mechanism 83, an air exhaust mechanism guide rail pair 831, an air exhaust mechanism screw pair 832, a pair of sealing knives 84, a set of sealing knife driving units 85, a pair of pressing strips 86, a set of pressing strip driving units 87, a sealing knife guide rail pair 88 and a pressing strip guide rail pair 89. The second frame 81 is fixed on the whole machine frame, the moving frame guide rail pair 821 is fixed on the second frame 81, and the second moving frame 82 is slidably connected on the moving frame guide rail pair 821 and connected with the moving frame lead screw pair 822, so that the second moving frame 82 can move in a third direction. The moving frame guide rail pair 821 and the moving frame screw pair 822 together constitute a driving device of the suction mechanism 83. The pumping mechanism guide rail pair 831 is fixed on the second moving frame 82, and the pumping mechanism 83 is slidably connected to the pumping mechanism guide rail pair 831 and fixed and connected with the pumping mechanism screw pair 832, so that the pumping mechanism 83 can also move in the third direction. The pressing strip 86 is used for limiting, the sealing knife 84 is used for sealing, and the pressing strip 86 and the sealing knife 84 jointly form a sealing device. The pressing bar 86 includes an upper pressing bar 861 and a lower pressing bar 862 oppositely arranged in the second direction, and the upper pressing bar 861 and the lower pressing bar 862 are connected with the second moving frame 82 through a pressing bar guide rail pair 89. In the specific embodiment, the upper press strip 861 and the lower press strip 862 are driven by the press strip driving unit 87 to approach each other, so as to press the upper and lower layers of the packaging bag and the suction nozzle 830 extending into the front end of the suction mechanism 83 between the upper and lower layers of the packaging bag, and the suction mechanism 83 vacuumizes the packaging bag. After the air in the packaging bag is exhausted, the air exhaust mechanism 83 moves reversely, the suction nozzle 830 withdraws from the packaging bag, the pressing strip 86 keeps pressing the upper layer and the lower layer of the packaging bag continuously, and then the heat sealing is carried out by the sealing knife 84. The seal blade 84 includes an upper seal blade 841 and a lower seal blade 842 disposed oppositely in the second direction, the upper seal blade 841 and the lower seal blade 842 being connected to the second moving frame 82 via a seal blade rail pair 88, the upper seal blade 841 and the lower seal blade 842 being capable of approaching each other by the driving of the seal blade driving unit 85 for heat sealing. After the heat seal is completed, the bead 86 and the sealing knife 84 are withdrawn in reverse.

In a preferred embodiment of the present invention, the package bag with the box and heat-sealed is conveyed to the shaping rotary table 10 by the third conveying device 9, shaped, and then conveyed to the discharge table 18 by the second conveying device 17, but in other embodiments, the package bag with the box and heat-sealed may be conveyed to the discharge table 18 directly by the second conveying device 17 without shaping.

Referring to fig. 21, a second bottom supporting mechanism 91 is disposed at a bottom end of the third carrying device 9 (in the embodiment, a robot). Accordingly, the third transfer device 9 is transferred from the sealing module 8 to the shaping rotary table 10 so as to hold the main body of the wafer cassette 200, as in the second transfer device 17.

Referring to fig. 13 to 15, the shaping rotary platform 10 cooperates with the shaping module 11 and the tape roll releasing mechanism 16 to further shape the packaged bag with a box.

Referring specifically to fig. 13 and 14, the structure of the shaping rotary platform 10 is as follows: comprises a base 101, a first rotating mechanism 102, a rotating table 103 and a clamping mechanism 104.

In the preferred embodiment, the clamping mechanism 104 includes at least four, and in the particular embodiment six, clamping positions for the pouch-containing package 200 from four left, right, front, and rear orientations. The rotation of the first rotating mechanism 102 and the clamping of the clamping mechanism 104 cause the packaged package to be fixed to the rotating table 103 and to rotate together with the rotating table 103, so that the adhesive tape can be wound around the packaged package. Referring to fig. 15, the shaping module 11 has the following structure: comprises a second screw pair 111, a second linear module 112 connected to the second screw pair 111, and a slider pair 113 connected to the second linear module 112. The tape reel release mechanism 16 is disposed above the slider pair 113. The second screw pair 111, the second linear module 112 and the slider pair 113 are respectively driven by three motors to realize that the three-axis (X-axis, Y-axis and Z-axis) positioning and moving the tape roll releasing mechanism 16, so that the tape roll releasing mechanism 16 can move to the shaping rotary platform 10 in a three-dimensional space, and after the tape on the tape roll releasing mechanism 16 is attached to the packaging bag with the box, the shaping rotary platform 10 rotates to start to wind the tape on the packaging bag with the box.

In a preferred embodiment, referring to fig. 1, 9 and 10, the present invention has a two-labeling action. The method comprises the following steps: the label printer 12 prints the information labels of the products (the content on the information labels is different due to different products in the wafer cassette 200), which may be called as an information label discharging device; the label reel 13 and the label tearing module 14 are used cooperatively, the warning labels (the warning labels are all the same) wound on the label reel 13 are torn off by the label tearing module 14, and the combination of the label reel 13 and the label tearing module 14 can be called as a warning label discharging device. The structure of the label tearing module 14 is the prior art, and therefore, the present invention is not described in detail. The labeling robot 15 takes the information labels and/or the warning labels at the label discharging device away respectively and shifts the information labels and/or the warning labels to the bag entering module 5 to label the wafer cassette 200; after the wafer cassette 200 is bagged, heat-sealed and shaped, the labeling robot 15 further takes away the information label and/or the warning label from the label discharging device and shifts the information label and/or the warning label to the shaping rotary platform 10 to label the package bag which is packaged with the cassette and wound with the adhesive tape. Of course, in alternative embodiments, there may be only one labeling process, that is, after the labeling robot 15 takes the label from the label discharging device, only one label is attached to the wafer cassette 200 before the bag is inserted or only one label is attached to the wafer cassette 200 after the bag is inserted.

Referring to fig. 16 and 17, the discharging platform 18 has the following structure: including a fork 181, a second servo motor 182, a second stop 183, a second placement platform 184, and a detection photoelectric module 185.
