Description

Technical Field

[0001] This invention relates to a material container and an automated feeding system. Background Technology

[0002] Currently, in display panel manufacturing facilities, replenishment operations mostly use Lock & Lock boxes to hold materials. These Lock & Lock boxes are designed to require operators to manually open, unlock, and remove materials from the boxes, resulting in high labor costs for replenishment operations and the risk of contaminating or damaging materials. Summary of the Invention

[0003] In view of this, one object of the present invention is to provide an automated feeding system and a material container that can be used in the automated feeding system.

[0004] To achieve the above objectives, according to some embodiments of the present invention, a material receiving box includes a housing, a limiting mechanism, a top cover, and a locking mechanism. The housing is configured to receive material. The limiting mechanism is disposed on the inner wall of the housing and includes a limiting plate and a displacement mechanism. The displacement mechanism is connected to the limiting plate and configured to move the limiting plate. The top cover is configured to cover the housing and includes an interference structure corresponding to the limiting mechanism. When the top cover covers the housing, the interference structure is configured to interfere with the displacement mechanism, causing the displacement mechanism to move the limiting plate to an unfolded position. The locking mechanism includes a first locking member, a second locking member, and an unlocking button. The first and second locking members are respectively disposed on the top cover and the housing, and the first locking member is configured to be pluggably connected to the second locking member. The unlocking button is disposed on the first or second locking member and is configured to allow the first and second locking members to separate in response to pressure.

[0005] In one or more embodiments of the present invention, one of the first and second fasteners is a pin, and the other is a pin holder. The pin holder is configured to receive the pin, and the pin holder includes an unlock button.

[0006] In one or more embodiments of the present invention, the displacement mechanism includes a base and a rotating component. A limiting plate is movably disposed on the base. The rotating component is rotatably disposed on the base and abuts against the limiting plate. When the top cover covers the housing, the interference structure is configured to press against the rotating component to drive the rotating component to push the limiting plate to the unfolded position.

[0007] In one or more embodiments of the present invention, the limiting plate includes a guide post that passes through the base. The displacement mechanism also includes a spring that is sleeved on the guide post and abuts against the base.

[0008] In one or more embodiments of the present invention, the displacement mechanism further includes a roller disposed on the rotating component and configured to contact the limiting plate.

[0009] In one or more embodiments of the present invention, the interference structure includes a bump and a roller disposed on the bump, the roller being configured to contact the displacement mechanism.

[0010] According to some embodiments of the present invention, an automated feeding system includes a material receiving box, a box unlocking device, and a box gripping device. The material receiving box includes a top cover, a housing, and at least one locking mechanism configured to secure the top cover to the housing. The box unlocking device includes a placement platform and at least one moving part movably disposed on the placement platform. The box gripping device is configured to grip the material receiving box and move it to the placement platform. The moving part is configured to move toward the material receiving box and press the locking mechanism of the material receiving box to allow the top cover of the material receiving box to separate from the housing. The box gripping device is further configured to move the housing to a trolley after the top cover of the material receiving box has separated from the housing.

[0011] In one or more embodiments of the invention, the placement platform has at least one groove in which the moving component is disposed. The box unlocking device further includes an actuator connected to the moving component and configured to drive the moving component to move along the groove.

[0012] In one or more embodiments of the present invention, the material receiving box includes two locking mechanisms located on opposite sides of the material receiving box. The box unlocking device includes two moving parts disposed on opposite sides of the placement platform and configured to press the two locking mechanisms respectively.

[0013] In one or more embodiments of the present invention, the box gripping device includes a track and a gripping arm. The track extends above the box unlocking device, and the gripping arm is movably and vertically mounted on the track.

[0014] In summary, the material container of the present invention is equipped with a locking mechanism featuring an unlock button, allowing the material container to be unlocked by pressing the unlock button. Furthermore, the material container also includes a limiting mechanism linked to the upper cover. When the upper cover is closed, the interference structure of the upper cover interferes with the displacement mechanism of the limiting mechanism, causing the limiting plate of the limiting mechanism to automatically unfold and thus limit the material in the material container. Therefore, the opening, closing, and material limiting actions of the material container of the present invention can all be completed by automated equipment, saving manpower, preventing material contamination or damage, and improving yield.

[0076] To make the description of the present invention more detailed and complete, reference may be made to the accompanying drawings and the various embodiments described below. The elements in the drawings are not drawn to scale and are provided for illustrative purposes only. Many practical details are described below to provide a comprehensive understanding of the invention; however, those skilled in the art will understand that the invention can be practiced without one or more of these practical details, and therefore, these details are not intended to limit the invention.

[0077] Please refer to Figure 1 as well as Figure 2 The figures illustrate an assembly diagram and an exploded view of a material receiving box according to an embodiment of the present invention, wherein the material receiving box is placed on a box unlocking device. The material receiving box 12 is used to receive at least one material 24 (e.g., one or more stacked polarizers or photomasks), and can be applied to machine replenishment operations in display panel or semiconductor manufacturing facilities. The material receiving box 12 includes a top cover 21, a housing 22, and at least one locking mechanism 30. The housing 22 has a receiving space 23 for receiving the material 24. The top cover 21 is configured to cover the housing 22 to close the receiving space 23 of the housing 22. The locking mechanism 30 is disposed along at least one edge of the top cover 21 and at least one edge of the housing 22, and is configured to secure the top cover 21 to the housing 22. The locking mechanism 30 includes an unlocking button 35, which is configured to allow the top cover 21 to separate from the housing 22 in response to pressure. The aforementioned press-to-unlock design of the locking mechanism 30 allows the material container 12 to be unlocked and opened using automated equipment (such as the container unlocking device and container gripping device described below), without the need for manual operation by the operator.

[0078] like Figure 1 as well as Figure 2 As shown, the locking mechanism 30 further includes a first locking member 31 and a second locking member 32, which are respectively fixedly disposed on the upper cover 21 and the housing 22, and the first locking member 31 is configured to be pluggably connected to the second locking member 32. An unlocking button 35 is disposed on the first locking member 31 or the second locking member 32, and the unlocking button 35 is configured to allow the first locking member 31 and the second locking member 32 to separate in response to pressure.

[0079] like Figure 1 and Figure 2 As shown, in some embodiments, the first locking element 31 and the second locking element 32 are a pin and a pin holder, respectively. The pin holder has a slot configured to receive the pin. When the pin is inserted into the slot of the pin holder (and the unlock button 35 is not pressed), the pin engages in the slot (e.g., the pin has an opening that interferes with the latch in the slot when the pin is inserted), achieving automatic locking. The pin holder includes an unlock button 35, which allows the pin to leave the slot of the pin holder in response to pressure (e.g., the unlock button 35 releases the interference between the pin's opening and the latch in the slot when pressed). As described above, automatic unlocking can be achieved by pressing the unlock button 35 with an automated device. In other embodiments, the first locking element and the second locking element may also be a pin holder and a pin, respectively.

[0080] like Figure 1 and Figure 2 As shown, the material container 12 can be automatically unlocked by the container unlocking device 19. The container unlocking device 19 includes a placement platform 53 and at least one movable part 56 movably disposed on the placement platform 53. The placement platform 53 is used to support the material container 12. When the material container 12 is placed on the placement platform 53, the movable part 56 located on one side of the material container 12 can move toward the material container 12 and press the unlock button 35 of the locking mechanism 30 of the material container 12 to allow the top cover 21 of the material container 12 to separate from the housing 22.

[0081] like Figure 1 and Figure 2 As shown, in some embodiments, the placement platform 53 has at least one groove 57, in which the moving part 56 is disposed. The housing unlocking device 19 further includes an actuator 58 connected to the moving part 56 and configured to drive the moving part 56 to move along the groove 57. Driven by the actuator 58, the moving part 56 can move between an unlock position and a waiting position, wherein the moving part 56 in the unlock position abuts against the unlock button 35, and the moving part 56 in the waiting position (… Figure 1 as well as Figure 2 The movable component 56 (as shown in the diagram) is separated from the material receiving box 12. In some embodiments, the movable component 56 includes a protrusion 55 that corresponds to the unlock button 35 of the locking mechanism 30 and is configured to press against the unlock button 35.

[0082] It should be noted that actuator 58 is only shown as a rectangle in the figure, and its specific structure is not depicted. In practical applications, actuator 58 may include a solenoid valve, a linear motor, a rack and pinion mechanism, or other suitable actuators.

[0083] like Figure 1 and Figure 2As shown, in some embodiments, the material container 12 includes a plurality of locking mechanisms 30, such as a first locking mechanism M1 and a second locking mechanism M2, which are located on opposite sides of the material container 12 (located on opposite edges of the top cover 21 and opposite edges of the housing 22). The container unlocking device 19 includes a plurality of moving parts 56, such as a first moving part N1 and a second moving part N2, which are located on opposite sides of the placement platform 53 and configured to press the first locking mechanism M1 and the second locking mechanism M2 respectively. In this way, when the material container 12 is placed on the placement platform 53, the first moving part N1 and the second moving part N2 can clamp the material container 12 from both sides, preventing the material container 12 from moving arbitrarily, and ensuring that the unlocking button 35 of the locking mechanism 30 is pressed and successfully unlocked. In some embodiments, the material container 12 is generally rectangular, and a locking mechanism 30 is provided on all four sides of the material container 12. Correspondingly, a moving part 56 is provided on all four sides of the placement platform 53.

[0084] In some embodiments, the actuator 58 of the box unlocking device 19 is controlled by an automatic control system (not shown) that can drive the actuator 58 to actuate at a specific time to move the moving part 56 to the unlocked position. For example, an object detector may be installed on the placement platform 53, and when the object detector detects an object, the automatic control system can drive the actuator 58 to actuate. In another example, the automatic control system operates a box gripping device to place the material receiving box 12 onto the placement platform 53, and then drives the actuator 58 to actuate. The automatic control system may also control the actuator 58 in other ways.

[0085] like Figure 1 and Figure 2 As shown, in some embodiments, the material receiving box 12 further includes an adhesive strip 42 disposed on the end face of the housing 22 and surrounding the receiving space 23 of the housing 22. When the top cover 21 covers the housing 22, the adhesive strip 42 is held by the top cover 21 and the housing 22, giving the material receiving box 12 a dustproof and airtight effect. The adhesive strip 42 is, for example, an annular rubber strip. In some embodiments, the housing 22 has at least one groove 43 located on the outer side of the housing 22. The groove 43 allows automated equipment (such as the gripping arm of the box gripping device described below) to extend into and grip the top cover 21.

[0086] like Figure 1 and Figure 2As shown, the material receiving box 12 also includes at least one limiting mechanism 60, which is disposed on the inner wall of the housing 22 and includes a limiting plate 61 and a displacement mechanism 63. The displacement mechanism 63 is connected to the limiting plate 61 and configured to move the limiting plate 61. Specifically, the displacement mechanism 63 is configured to drive the limiting plate 61 to move between an unfolded position and a retracted position. When the material receiving box 12 contains material 24, the limiting plate 61 in the unfolded position abuts against the side of the material 24 to prevent the material 24 from sliding in the material receiving box 12. The limiting plate 61 can also move away from the material 24 to the retracted position and separate from the material 24.

[0087] like Figure 1 as well as Figure 2 As shown, in some embodiments, the material receiving box 12 includes a plurality of limiting mechanisms 60 disposed on adjacent sides of the inner wall of the housing 22. In some embodiments, the inner wall of the housing 22 has a groove 25, in which the limiting mechanism 60 is disposed. In some embodiments, the housing 22 includes at least one limiting protrusion 41, which is a fixed limiting structure that protrudes from the inner wall of the housing 22 and is disposed relative to the limiting mechanism 60 (in other words, the limiting protrusion 41 and the limiting mechanism 60 are disposed on opposite sides of the inner wall of the housing 22).

[0088] like Figure 1 and Figure 2 As shown, the upper cover 21 includes a cover plate 26 and at least one interference structure 27. The interference structure 27 is disposed on the surface of the cover plate 26 and protrudes from the surface of the cover plate 26. The interference structure 27 is configured to correspond to the limiting mechanism 60. When the upper cover 21 covers the housing 22, the interference structure 27 is configured to interfere with the displacement mechanism 63 of the limiting mechanism 60, thereby driving the displacement mechanism 63 to move the limiting plate 61 to the unfolded position. In this way, when the upper cover 21 is covered on the housing 22 (which can be performed by automated equipment), the limiting plate 61 of the limiting mechanism 60 unfolds automatically without manual operation by an operator.

[0089] like Figure 1 and Figure 2 As shown, in some embodiments, the interference structure 27 includes a protrusion 28 and a roller 29. The protrusion 28 is fixed to the cover plate 26. The roller 29 is rotatably disposed on the protrusion 28 and configured to contact the displacement mechanism 63. The contact between the roller 29 and the displacement mechanism 63 can prevent friction between the interference structure 27 and the displacement mechanism 63 from generating debris that contaminates the material 24. In some embodiments, the protrusion 28 is a U-shaped frame, the roller 29 is disposed in the recess of the U-shaped frame, and both ends of the roller 29 are pivotally connected to the U-shaped frame.

[0090] Please refer to Figure 3 as well as Figure 4 . Figure 3 For illustration Figure 2 The diagram shows the specific structure of the limiting mechanism. Figure 4 For illustration Figure 3 The diagram shows a cross-sectional view of the limiting mechanism at the mark 4-4'. In some embodiments, the displacement mechanism 63 includes a base 64 and a rotating component 65. The base 64 is fixedly disposed within the housing 22, and the limiting plate 61 is movably disposed on the base 64. Specifically, the limiting plate 61 can be translated relative to the base 64 along a first direction D1 toward the center of the accommodating space 23, or along a second direction D2 opposite to the first direction D1. The rotating component 65 is rotatably disposed on the base 64 and abuts against the limiting plate 61. When the limiting plate 61... Figure 3 and Figure 4 When the position shown is closed, the limiting plate 61 separates from the material 24 disposed in the accommodating space 23.

[0091] Please refer to the above as well. Figure 5 . Figure 5 For illustration Figure 4 A schematic diagram showing the limit mechanism when deployed. Figure 5 As shown, when the upper cover 21 covers the housing 22, the interference structure 27 provided on the upper cover 21 is configured to press against the rotating member 65, causing the rotating member 65 of the pivot base 64 to rotate and push the limiting plate 61. The limiting plate 61 is pushed by the rotating member 65 and moves to the unfolded position along the first direction D1.

[0092] like Figures 3 to 5 As shown, in some embodiments, the displacement mechanism 63 further includes a roller 66 disposed on the edge of the rotating member 65 adjacent to the limiting plate 61 and configured to contact the limiting plate 61. The contact of the roller 29 with the limiting plate 61 can prevent friction between the limiting plate 61 and the displacement mechanism 63 from generating debris that contaminates the material 24.

[0093] like Figures 3 to 5 As shown, in some embodiments, the base 64 includes a back plate portion 74 fixedly connected to the housing 22, two baffle portions 73 opposite to the back plate portion 74, and a connecting portion 75 connecting the back plate portion 74 and the baffle portions 73. The back plate portion 74, the baffle portions 73, and the connecting portion 75 form a generally U-shaped structure. When the limiting plate 61 is in the retracted position, the limiting plate 61 abuts against the baffle portions 73. The two baffle portions 73 are separated from each other and each has a folded edge 77. A rotating member 65 is disposed between the two baffle portions 73 and pivotally connected to the folded edges 77 of the two baffle portions 73. The folded edges 77 have through holes 79, and the rotating member 65 has a laterally protruding pivot 62, which is rotatably disposed in the through holes 79.

[0094] like Figures 3 to 5As shown, in some embodiments, the rotating component 65 includes a first extension 71 and a second extension 72, the first extension 71 being connected to and bent relative to the second extension 72. A hub 62 is located at the intersection of the first extension 71 and the second extension 72. The first extension 71 is used to push the limiting plate 61, while the second extension 72 is used to be pressed against by the interference structure 27 of the upper cover 21 to drive the rotating component 65 to rotate.

[0095] like Figures 3 to 5 As shown, in some embodiments, the limiting plate 61 includes a plate body 67 and at least one guide post 68. The guide post 68 is connected to the plate body 67 and is movably disposed through the baffle portion 73 of the base 64. The guide post 68 has a first end 81 and a second end 82. The first end 81 is connected to the plate body 67, and the second end 82 is opposite to the first end 81, with the width of the second end 82 increasing to form a stop structure. The displacement mechanism 63 also includes a spring 69 (e.g., a tension spring or a spring sheet). The spring 69 is sleeved on the guide post 68, and both ends of the spring 69 abut against the baffle portion 73 of the base 64 and the stop structure of the second end 82 of the guide post 68, respectively. When the limiting plate 61 moves to the unfolded position, the spring 69 is compressed due to the movement of the guide post 68. When the upper cover 21 is lifted, the force exerted on the rotating component 65 by the interference structure 27 is released, the spring 69 can reset the limiting plate 61 by its restoring force (that is, to move the limiting plate 61 back to the closed position).

[0096] like Figures 3 to 5 As shown, the displacement mechanism 63 is equipped with a rotating component 65 to push the limiting plate 61. The distance by which the rotating component 65 pushes the limiting plate 61 outward depends on the height of the interference structure 27. When the interference structure 27 is higher, the displacement of the limiting plate 61 caused by the rotating component 65 is larger, while when the interference structure 27 is lower, the displacement of the limiting plate 61 caused by the rotating component 65 is smaller. Therefore, for the material receiving box 12, only the height of the interference structure 27 needs to be adjusted to accommodate materials 24 of different sizes.

[0097] Please refer to Figures 6 to 8 This is a schematic side view illustrating an automated replenishment system 13 according to an embodiment of the present invention at different operating stages. The automated replenishment system 13 includes a carrier 15, a trolley 16, a box gripping device 17, and the aforementioned material receiving box 12 and box unlocking device 19. The carrier 15 and the trolley 16 are used to transport the material receiving box 12, while the box gripping device 17 is configured to grip and move the material receiving box 12. The carrier 15 is, for example, an automated guided vehicle (AGV).

[0098] like Figures 6 to 8As shown, in some embodiments, the replenishment operation performed by the automated replenishment system 13 sequentially includes the following steps: (1) a carrier 15 transports one or more material receiving boxes 12 containing materials from the warehouse to the box gripping device 17; (2) the box gripping device 17 grips the material receiving box 12 placed on the carrier 15 and moves the material receiving box 12 to the placement platform 53 of the box unlocking device 19; (3) the moving part 56 of the box unlocking device 19 moves toward the material receiving box 12 placed on the placement platform 53 and presses the unlocking button 35 of the locking mechanism 30 of the material receiving box 12 to allow the upper cover 21 of the material receiving box 12 to separate from the housing 22; (4) the box gripping device 17 grips the upper cover 21 and separates the upper cover 21 from the housing 22, at which time the limiting plate 61 of the limiting mechanism 60 of the material receiving box 12 automatically retracts (see reference). Figure 4 (5) The box gripping device 17 grips the shell 22 and moves the shell 22 to the trolley 16; (6) The trolley 16 transports the shell 22 and the material placed in the shell 22 together to the machine that needs to be replenished (not shown). In some embodiments, the automated replenishment system 13 also includes an automatic control system (not shown), which is configured to control the automated operation of components such as the carrier 15, the box gripping device 17, and the box unlocking device 19 of the automated replenishment system 13.

[0099] like Figures 6 to 8 As shown, in some embodiments, the box gripping device 17 includes a track 44 and a gripping arm 45 (e.g., a mechanical gripper). The track 44 extends above the box unlocking device 19 and also above the location where the carrier 15 and the trolley 16 are parked. The gripping arm 45 is movably and vertically mounted on the track 44 and configured to grip the material receiving box 12.

[0100] In summary, the material container of the present invention is equipped with a locking mechanism featuring an unlock button, allowing the material container to be unlocked by pressing the unlock button. Furthermore, the material container also includes a limiting mechanism linked to the upper cover. When the upper cover is closed, the interference structure of the upper cover interferes with the displacement mechanism of the limiting mechanism, causing the limiting plate of the limiting mechanism to automatically unfold and thus limit the material in the material container. Therefore, the opening, closing, and material limiting actions of the material container of the present invention can all be completed by automated equipment, saving manpower, preventing material contamination or damage, and improving yield.

[0101] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the appended claims.
