Description

Technical Field

[0001] This invention relates to a front-opening material box (FOUP), and particularly to a method and apparatus for cleaning the material box. Background Technology

[0002] A front-opening material box (FOUP) consists of a housing with a compartment, which is locked together with a door. The material box can accommodate wafers, substrates, or panels through the compartment, facilitating the transport of the material box to multiple workstations using an overhead crane (OHT) to enable the contents to undergo necessary processing.

[0003] Furthermore, it is known that, due to process requirements, the material box often needs to be filled with gases such as nitrogen (N2) to maintain the process quality of the contents. The material box must be cleaned after a period of use to remove harmful substances accumulated or remaining on the housing and door panels, thereby maintaining the production yield of the aforementioned process components. These harmful substances include particulate matter, volatile organic compounds (VOCs), sulfur dioxide (SO2), ammonia, acids, and NH3.

[0004] Therefore, among the multiple processing stations set up on the production line according to process requirements, a cleaning station is often added specifically for this material box. Please refer to [link / reference]. Figure 1a As shown, a cleaning station 200 specifically configured for cleaning the material box 10 is disclosed in the prior art. The material box 10 can be automatically placed in at least one load port 280 of the cleaning station 200 by means of the overhead crane for connecting the material box brought by the overhead crane to enter and exit the cleaning station 200.

[0005] The cleaning station 200 typically houses a multi-axis robotic arm 270, multiple cleaning machines 220, 230, and 240 for wet cleaning and vacuum drying, an unlocking station 250, and a testing station 260. The robotic arm 270 is equipped with a gripper 271 (or clamp) capable of grasping the material box 10, the housing 11, and the door panel 12. The unlocking station 250 and the testing station 260 are located at the ends of the cleaning machines 220, 230, and 240, respectively. This configuration allows the robotic arm 270 to grip and place the material box 10 from the loading port 280, and transport the material box 10 to the unlocking station 250 to unlock it into a state where the housing 11 and door panel 12 are separated. This facilitates the individual transport of the housing 11 and door panel 12 to the inspection station 260 for defect detection, thereby eliminating defective housing 11 and door panel 12. Subsequently, the robotic arm 270 transports the good housing 11 and door panel 12 to multiple cleaning machines 220, 230, and 240 for wet cleaning and vacuum drying. Afterward, the robotic arm 270 transports the cleaned housing 11 and door panel 12 to the unlocking station 250 to lock them together into the material box 10.

[0006] However, the existing technology described above, which sets up the unlocking station 250 and the detection station 260 separately in the cleaning zone station 200, obviously increases the number of workstations in the cleaning and handling process, that is, increases the operation time of the robotic arm 270 in the cleaning process of the handling housing 11 and the door panel 12, thus which is not conducive to improving the cleaning efficiency of the material box.

[0007] Furthermore, the handle 271 currently used in the cleaning station 200 can generally only grip one of the material box 10, the housing 11, or the door panel 12 at a time. This causes the robotic arm 270 to frequently move back and forth between the housing 11 and the door panel 12 of the material box in multiple trips between the unlocking station 250 and the multiple cleaning machines 220, 230, and 240, which increases the time spent on handling and reduces the operating efficiency of the cleaning station.

[0008] Please continue reading. Figure 1bAs shown, the housing 11 and door 12 of the material box 10 are unlocked and separated. The housing 11 has an opening 110, which forms a chamber 111 for accommodating multiple items. The chamber 111 has multiple guide ribs 112 arranged in rows and corresponding to each other on both sides. The outer wall of one side of the housing 11 has a flange 113 (commonly known as a mushroom head) for the crane to pick up. The outer wall of the housing 11 also has multiple screws 114 for locking the multiple rows of guide ribs 112 in the opening 110. In addition, the inner wall periphery of the door panel 12 is provided with a gas-stopping strip 120 and a row of guide ribs 121. The gas-stopping strip 120 serves to prevent gas leakage after the door panel 12 is closed and locked with the housing 11. The row of guide ribs 121 on the door panel 12 and the row of guide ribs 112 in the housing 11 can be layered and correspond to each other, and surround the periphery of the cavity 111 to guide the wafer, carrier plate, or panel and other accommodating objects in a layered manner. Please also refer to... Figure 1c The bottom of the housing 11 is exposed to have a pair of exhaust valve ports 13 and a pair of intake valve ports 14, as well as a plurality of screw holes 15 for screws to pass through and lock into the inner wall of the cavity, for assembling screws to lock some functional components.

[0009] However, after a period of use, the housing 11, the door panel 12, and their guide ribs 112 and 121 may develop defects such as skewing, deformation, or breakage. In addition, the gas-stopping strip 120 may also age or break, causing defects in the material box 10. The aforementioned defects in the housing and the door panel must be eliminated from the production line to avoid affecting the normal function of the material box.

[0010] To detect the aforementioned defects in the material box 10 on the production line, existing technologies include adding defect detection to the cleaning process of the material box 10. Further details can be found in the following sections. Figure 1a It was revealed that an inspection station 260 was also added within the aforementioned clean processing area station 20 to detect defects in the housing 11 and door panel 12.

[0011] However, the existing technology described above places the detection station 260 between the unlocking station 250 and the cleaning machines 220, 230, and 240, which also increases the number of workstations in the cleaning and handling process. This affects the operation time of the robotic arm 270 in the sequential unlocking, defect detection, cleaning, and locking process of the handling housing 11 and the door panel 12. Therefore, it is still not conducive to improving the cleaning efficiency of the material box. All of the above problems need to be improved. Summary of the Invention

[0012] In view of this, the purpose of the present invention is to provide an operation method and apparatus for cleaning material boxes. The present invention focuses on the problem that the operation process of unlocking, handling and defect detection of material boxes in the existing material box cleaning station increases the cleaning operation time of the material box, and proposes an improvement strategy. In particular, it includes improving the setting position of the unlocking station and the detection station, as well as the gripping and handling mode of the handle (i.e., jig) attached to the robotic arm, thereby shortening the cleaning operation time of the material box.

[0013] Therefore, a preferred embodiment of the present invention provides an operation method for cleaning a material box, applied in a cleaning station for the material box. The cleaning station includes at least one loading port for placing the material box, a plurality of cleaning machines for cleaning the material box, and a robotic arm for moving the material box between the at least one loading port and the plurality of cleaning machines. The at least one loading port is provided with an unlocker for unlocking the material box into a housing and a door, and for locking the housing and the door into the material box. The robotic arm is equipped with a handle, the two ends of which are respectively provided with a first gripper and a second gripper. The operation method includes: using the at least one loading port... The unlocker on the loading port unlocks and opens the door panel on the housing. Then, the first gripper of the handle grips the housing from at least one of the loading ports, and the second gripper of the handle grips the door panel from at least one of the loading ports. This drives the handle to simultaneously transport the housing and the door panel from at least one of the loading ports and place them one by one into multiple cleaning machines for cleaning. The handle then grips the housing and the door panel cleaned by multiple cleaning machines one by one. This drives the handle to simultaneously transport the housing and the door panel from multiple cleaning machines to at least one loading port. The unlocker then engages the door panel with the housing and locks it into the cleaned material box.

[0014] In a further implementation, the unlocker uses either a gyratory or linear movement to open the door panel on the housing. Furthermore, the robotic arm drives the handle to reciprocate and rotate at a predetermined angle, causing the first gripper to grip and release the housing, and the second gripper to grip and release the door panel. The double-end faces of the first and second grippers are parallel and corresponding to each other, and the predetermined angle is 180 degrees. The first gripper grips a flange on the housing, and the second gripper grips both ends of the door panel.

[0015] In a further implementation, at least one photosensitive coupling element is provided around at least one of the loading ports. The operation method further includes detecting the quality of the housing and the door panel by means of at least one of the photosensitive coupling elements of at least one of the loading ports after the unlocker unlocks and opens the door panel on the housing, and before the handle picks up the housing and the door panel. The housing and the door panel have multiple internal standard features of the finished product specifications. The at least one photosensitive coupling element is used to detect multiple internal condition features of the housing and the door panel. The operation method further includes comparing the differences between the internal condition features and the internal standard features to determine the location of defects in the housing and the door panel, selecting good products of the housing and the door panel, and having the handle pick up and transport the unlocked good products of the housing and the door panel from at least one of the loading ports to multiple cleaning machines for cleaning. Furthermore, the internal standard features are constituted by at least one inner end face standard image of the housing and the door panel, and the internal condition features are respectively constituted by at least one inner end face condition image of the housing and the door panel. The housing and the door panel also have multiple external standard features according to the finished product specifications. The operation method further includes, before unlocking and opening the door panel on the housing, detecting multiple external condition features of the housing and the door panel, and comparing the differences between the external condition features and the external standard features. Moreover, the photosensitive coupling element detects the external condition features and the internal condition features in at least one fixed and one movable manner. The external standard features are constituted by at least one outer end face standard image of the housing and the door panel, and the external condition features are constituted by at least one outer end face condition image of the housing and the door panel.

[0016] In a further implementation, at least one of the loading ports includes at least one inlet port and at least one outlet port. The operation of unlocking the material box to become the housing and the door panel is performed at at least one of the inlet ports, and the operation of locking the housing and the door panel to become the material box is performed at at least one of the outlet ports. Specifically, at least one of the inlet ports unlocks the door panel on the housing using a door opener, and at least one of the outlet ports locks the door panel on the housing using a door closeer. The door closeer opens the door panel on the housing using either a gyratory or linear movement method.

[0017] The present invention also provides an operating device for cleaning a material box capable of performing the above-described operating method, disposed in a cleaning station of the material box, for unlocking the material box to become a housing and a door, moving the housing and the door for cleaning, and locking the cleaned housing and the door to become the material box; the cleaning station includes at least one loading port for placing the material box, a plurality of cleaning machines for cleaning the material box, and a robotic arm for moving the material box between the at least one loading port and the plurality of cleaning machines, the at least one loading port having a platform for placing the material box; the operating device includes an unlocker and a handle; the unlocker is disposed in a... Adjacent to the countertop, the unlocker has a pair of keys that can be inserted into a pair of lock holes on one of the door panels to unlock and open the door panel on the housing, and to lock the housing and the door panel into the material box; the handle is attached to the robotic arm, and a first gripper and a second gripper are respectively disposed on the two ends of the handle. The first gripper is used to grip and release the housing between at least one of the loading ports and the cleaning station, and the second gripper is used to grip and release the door panel between at least one of the loading ports and the cleaning station; wherein, the robotic arm drives the handle to reciprocate and rotate at a predetermined angle, causing the first gripper to grip and release the housing, and the second gripper to grip and release the door panel.

[0018] In a further embodiment, the unlocker has a base capable of supporting the door panel, with the pair of keys protruding outward from a base surface of the base. The base has a pivot portion, which is pivotally connected to the end side of the platform of at least one of the loading ports, allowing the base to rotate to insert the pair of keys into the pair of keyholes of the door panel, thereby unlocking and opening the door panel on the housing. Alternatively, the base can slide along the end side of the platform of at least one of the loading ports via a linear guide rail, allowing the base to move linearly to insert the pair of keys into the pair of keyholes of the door panel, thereby unlocking and opening the door panel on the housing.

[0019] In a further embodiment, the operating device also includes the photosensitive coupling element suspended around the platform of at least one of the loading ports, for detecting multiple current features of the housing and the door after unlocking at at least one of the loading ports.

[0020] In a further embodiment, at least one of the loading ports is at least one inlet port for placing the material box, and the cleaning station also includes at least one outlet port, wherein the outlet port is locked by a door closer to the door panel on the housing, forming the material box. The door closer is disposed at one end of the platform of one of the outlet ports, and the door closer has a pair of keys inserted into a pair of lock holes on one of the door panels for holding the door panel and locking the door panel on the housing.

[0021] Furthermore, the door closer has a base capable of supporting the door panel, with the pair of keys protruding outward from one base surface of the base. The base has a pivot portion, which is pivotally connected to the end side of the platform of the discharge port, allowing the base to rotate and insert the pair of keys into the pair of lock holes of the door panel, supporting the door panel and locking it on the housing. Alternatively, the base slides along the end side of the platform of the discharge port via a linear guide rail, allowing the base to move linearly and insert the pair of keys into the pair of lock holes of the door panel, supporting the door panel and locking it on the housing.

[0022] Implemented accordingly, and compared to the prior art, since the processes of unlocking the material box and detecting the housing and the door panel of the present invention are all performed at at least one of the loading ports, and the handle can grip, transport, and release the housing and the door panel in one go, unlike the traditional method where the processes of unlocking the material box and detecting the housing and the door panel are all performed at... Figure 1a The cleaning station 200 shown is equipped with a robotic arm 270 for material handling, thus the present invention has the following advantages:

[0023] (1) Saving Figure 1a The operation time of the robotic arm 270 in sequentially unlocking, defect detection, cleaning and locking the conveying housing 11 and door 12 is shown.

[0024] (2) In Figure 1a The shell 11 or door piece 12 that is identified as defective by the defect detection at the inspection station 260 shown can be directly removed by the overhead crane or other automatic equipment to eliminate the defective products from the production line. This avoids the robotic arm 270 in the cleaning station 200 from picking up the shell 11 or door piece 12 that already has defects for cleaning, thereby improving the cleaning efficiency of good products.

Detailed Implementation

[0044] As shown in the figure, the present invention provides an operation method for cleaning a material box, applied in a cleaning station for the material box. The cleaning station includes at least one loading port for placing the material box, a plurality of cleaning machines for cleaning the material box, and a robotic arm for moving the material box between the at least one loading port and the plurality of cleaning machines. The at least one loading port is provided with an unlocker for unlocking the material box into a housing and a door, and for locking the housing and the door into the material box. The robotic arm is equipped with a handle, the two ends of which are respectively provided with a first gripper and a second gripper. The operation method includes: using the at least one loading port... The unlocker on the port unlocks and opens the door panel on the housing. Then, the first gripper of the handle grips the housing from at least one of the loading ports, and the second gripper of the handle grips the door panel from at least one of the loading ports. This drives the handle to simultaneously transport the housing and the door panel from at least one of the loading ports and place them one by one into multiple cleaning machines for cleaning. The handle then grips the housing and the door panel cleaned by multiple cleaning machines one by one. This drives the handle to simultaneously transport the housing and the door panel from multiple cleaning machines to at least one loading port. The unlocker then engages the door panel with the housing and locks it into the cleaned material box.

[0045] This invention provides an operating device for cleaning a material box, configured in a cleaning station of the material box, for unlocking the material box to become a housing and a door, moving the housing and the door for cleaning, and locking the cleaned housing and the door back into the material box; the cleaning station includes at least one loading port for placing the material box, multiple cleaning machines for cleaning the material box, and a robotic arm for moving the material box between the at least one loading port and the multiple cleaning machines, wherein the at least one loading port has a platform for placing the material box. The operating device includes: an unlocker having a pair of keys that can be inserted into a pair of lock holes on one of the door panels to unlock and open the door panel on the housing, and to lock the housing and the door panel into the material box; and a handle attached to the robotic arm, wherein a first gripper and a second gripper are respectively disposed on the two ends of the handle, the first gripper being used to grip and release the housing between at least one of the loading ports and a plurality of the cleaning stations, and the second gripper being used to grip and release the door panel between at least one of the loading ports and a plurality of the cleaning stations;

[0046] The unlocker is disposed on one end of at least one of the loading ports and adjacent to the table surface. The robotic arm drives the handle to reciprocate and rotate at a predetermined angle, thereby enabling the first gripper to grip and release the housing, and the second gripper to grip and release the door panel.

[0047] The unlocker has a base that supports the door panel, the pair of keys protruding outward from a base surface of the base, and the base has a pivot portion that is pivotally connected to the end side of the platform of at least one of the loading ports, so that the base can rotate to insert the pair of keys into the pair of lock holes of the door panel, thereby unlocking and opening the door panel on the housing.

[0048] The unlocker has a base that supports the door panel, the pair of keys protruding outward from a base surface of the base, and the base is slidably mounted on the end side of the platform of at least one of the loading ports via a linear slide rail, so that the base can linearly move to insert the pair of keys into the pair of lock holes of the door panel, thereby unlocking and opening the door panel on the housing.

[0049] It also includes at least one photosensitive coupling element suspended around the platform of at least one of the loading ports, for detecting multiple current features of the housing and the door after unlocking at at least one of the loading ports.

[0050] The photosensitive coupling element is suspended around the platform of at least one loading port in at least one manner, either fixed or movable.

[0051] The loading port includes at least one inlet port and at least one outlet port for placing the material box. The unlocker includes a door opener installed on the tabletop side of the inlet port and a door closeer installed on the tabletop side of the outlet port. The door opener is used to unlock and open the door panel on the housing, and the door closeer is used to engage and lock the door panel on the housing to form the material box.

[0052] First, please refer to Figure 2 As shown, the present invention discloses an operating device for cleaning the material box 10, which is disposed in a cleaning station 20 of the material box 10. The cleaning station 20 is equipped with at least one loading port 21 for placing the material box 10, a plurality of cleaning machines 23 for cleaning the material box 10, and a robotic arm 27 for moving the material box 10 between the at least one loading port 21 and the plurality of cleaning machines 23. The loading port 21 has a platform 210, which can first provide a place for the material box 10 to be cleaned, and then provide a place for the cleaned material box 10. Furthermore, each of the plurality of cleaning machines 23 can be equipped with wet cleaning or vacuum drying capabilities. Figure 1bThe material box 10 shown has functions such as housing 11 and door panel 12; furthermore, the robotic arm 27 can also be replaced by an automated machine with multi-axis movement capability, so that multiple or a single loading port 31 and multiple cleaning machines 23 can surround the periphery of the robotic arm 27, driving the robotic arm 27 to move the housing 11 and door panel 12 between the loading port 21 and multiple cleaning machines 23.

[0053] Please refer to both together. Figure 2 and Figure 3 As shown, the multiple loading ports 21 of the cleaning station 20 can be divided into at least one inlet port 211 and one or more outlet ports 212. The inlet port 211 is dedicated to the overhead crane (OHT) for transporting and placing the material box 10 to be cleaned. The outlet port 212 is dedicated to the robotic arm 27 within the cleaning station 20 for transporting and placing the cleaned material box 10. The more inlet ports 211 and outlet ports 212 there are, the more temporary areas the material boxes 10 can serve, thus avoiding the time spent by the overhead crane waiting to place materials and by the robotic arm 27 waiting to retrieve materials. In other words, in alternative implementations, only one loading port 21 is needed, while simultaneously providing placement for material boxes before and after cleaning. Although this is more time-consuming, it is still within the scope of applicable technology. In other words, the present invention is not limited to the loading port 21 being an inlet, outlet, or having both inlet and outlet functions simultaneously, nor is it limited to the number of such ports.

[0054] Based on the above-described configuration of the cleaning station 20, the operating device provided by the present invention can be installed, which includes an unlocker 30 mounted on at least one of the loading ports 21 and a handle 40 (or jig) attached to the robotic arm 27; in addition, the operating device of the present invention may optionally include at least one photocoupler 50 (CCD).

[0055] For example Figure 2 and Figure 3 As shown, the unlocking device 30 is further disclosed to be disposed at one end of the platform 210 of the loading port 21, for unlocking the material box 10 to be cleaned and before it is unlocked. Figure 1b The housing 11 and door panel 12 are shown; in addition, the unlocker 30 can also provide the housing 11 and door panel 12 to lock into the material box 10 after cleaning. Furthermore, the unlocker 30 has a pair of keys 33 inserted into the paired keyholes of the door panel 12 for unlocking the material box 10 and opening the door panel 12 on the housing 11.

[0056] like Figure 3As shown, the unlocker 30 has a base 32 that can support the door panel 12, and the pair of keys 33 protrude outward from a base surface 320 of the base 32. When the loading port 21 is divided into the inlet port 211 and the outlet port 212, the unlocker 30 can be divided into a door opener 31 installed on the end side of the table 210 of the inlet port 211, and a door closeer 34 installed on the end side of the table 210 of the outlet port 212; wherein, the door opener 31 at the inlet port 211 is specifically responsible for unlocking and opening the door panel 12 on the housing 11, and the door closeer 34 at the outlet port 212 has the same structure as the door opener 31 and is specifically responsible for driving the door panel 12 to engage with the housing 11 and lock it into the material box 10.

[0057] Furthermore, Figure 3 The unlocker 30 shown is implemented in a swing-type configuration; specifically, the base 32 has a pivot portion 321 and at least one arm portion 322 connected between the pivot portion 321 and the base 32; the base 32 is pivotally connected to the end side of the platform 210 of the loading port 21 by means of the arm portion 322 and the pivot portion 321, so that the base 32 can swing to insert the pair of keys 33 into the pair of lock holes of the door piece 12, thereby unlocking and opening the door piece 12 on the housing 11.

[0058] In addition, please see Figure 4 As shown, the unlocker 30 is implemented in a track sliding configuration; specifically, the base 32 can be disposed on a slide block 35, which is slidably disposed on a linear slide rail 36, so that the slide block 35 can drive the base 32 to move biaxially. Figure 4 (Indicated by a double-headed arrow), and thus situated on the end side of the platform 210 of the loading port 21, the base 32 allows the paired keys 33 to be inserted into the paired lock holes of the door piece 12 in a biaxial linear movement manner, thereby unlocking and opening the door piece 12 on the housing 11. Such designs for unlocking and closing the door piece 12 fall within the technical scope of this invention, which can be easily modified and applied.

[0059] For example Figure 2 and Figure 3 As shown, at least one of the photosensitive coupling elements 50 can be suspended around the platform 210 of the loading port 21 by means of a bracket or drive element (not shown) used as a fixed end, in order to detect multiple current characteristics of the housing 11 and the door panel 12 before the material box 10 to be cleaned is unlocked and ready to be cleaned, and thus determine whether the housing 11 and the door panel 12 to be cleaned have defects (described in detail later).

[0060] in, Figure 3The disclosure allows for the use of one or more of the aforementioned photosensitive coupling elements 50, suspended around the platform 210 of the loading port 21, in at least one of fixed or movable configurations, to detect the current characteristics. When there are multiple photosensitive coupling elements 50, they may include openings 110 corresponding to the housing 11 (e.g., ...). Figure 1b A first photosensitive coupling element 51 for taking an image at the position, and a second photosensitive coupling element 52 for taking an image at the outer wall surface of the door panel 12, or at the outer wall surface of the door panel 12 and the top position of the housing 11 (including the flange 113), to detect the current characteristics of the housing 11 and the door panel 12.

[0061] In this invention, the current condition characteristics of the housing 11 and the door plate 12 are detected by the photosensitive coupling element 50 and must be compared with the standard product of the material box 10 to identify whether there are defects in the material box 10 inspected on the production line.

[0062] Since the standard material box 10 itself has multiple standard features S in shape and structure, and the multiple standard features S should include multiple internal standard features S1 and multiple external standard features S2 formed on the shell 11 and the door panel 12; in other words, the multiple internal standard features S1 construct multiple standard images of the inner wall surfaces of the shell 11 and the door panel 12 (including those composed of shape and structural contours), and the multiple external standard features S2 construct the shape and structural contours of the multiple outer wall surfaces of the shell 11 and the door panel 12; in other words, the multiple internal standard features S1 and the multiple external standard features S2 can jointly construct a complete three-dimensional image of the inner and outer wall surfaces of the material box 10.

[0063] Correspondingly, the present invention detects the condition feature N of the material box 10 on the production line through the photosensitive coupling element 50, which also includes multiple internal condition features N1 and multiple external condition features N2 presented by the inner and outer wall surfaces of the housing 11 and the door panel 12 being inspected on the production line. The multiple internal condition features N1 should be compared with multiple internal standard features S1 to determine whether there are defects in the shape and contour of the inner wall surface of the housing 11 and the door panel 12 being inspected; and the multiple external condition features N2 should be compared with multiple external standard features S2 to determine whether there are defects in the shape and contour of the outer wall surface of the housing 11 and the door panel 12 being inspected.

[0064] Please refer to both together. Figure 5 and Figure 6 As shown; where, Figure 5 Exposure attached to Figure 2The three-dimensional shape of the first angle of the grabber 40 on the robotic arm 27 shown illustrates that the grabber 40 can be formed as a frame shape with two end faces 41 and 42. The two end faces 41 and 42 can be implemented as corresponding shapes that are parallel to each other. One side of the grabber 40 has a connecting seat 43 for locking the automatic tool 30. One end face 41 of the grabber 40 is provided with a first clamp 44 that can clamp the flange 113 on the housing 11. Figure 6 The other end face 42 of the handle 40 is provided with a second clamp 45 capable of gripping the opposite end edge of the door panel 12. The first clamp 44 and the second clamp 45 are respectively driven by a driver 441 and 451 to have the ability to expand and contract the clamping jaws.

[0065] For example Figure 7 As shown, the first clamp 44 and the second clamp 45, which expose the double end faces 41 and 42 of the handle 40, can perform a 180-degree flipping action via the handle 40 to clamp the flange 113 on the housing 11 and the opposite end edges 122 and 123 of the door piece 12, respectively.

[0066] Based on the above-described operating device, the present invention provides an operating method for cleaning the material box 10. Please refer to [link / reference needed]. Figure 8 The invention discloses the operation process of cleaning the material box. First, before performing the operation method of the invention, it is necessary to rely on an overhead crane (OHT) to transport the material box 10 to be cleaned on the production line to the feed port 211 (or loading port 21) for placement (e.g., ...). Figure 3 (As shown), then perform the following steps S10 to S40:

[0067] Step S10: Unlock and open the door panel on the housing.

[0068] This step will be based on Figure 3 Taking the configuration shown as an example, the door panel 12 on the housing 11 is unlocked and opened by using the door opener 31 (or unlocker 30) configured on the end side of the table 210 at the feed port 211. Specifically, the material box 10 (such as...) placed at the feed port 211 (or loading port 21) is transported by an overhead crane (OHT). Figure 3 As shown), the outer wall surface of the door panel 12 is exposed towards the base 32 of the door opener 31; Figure 3 In the example shown, the base 32 of the door opener 31 is horizontally positioned, so that the base surface 320 faces upwards, revealing a pair of keys 33.

[0069] Please continue reading Figure 9 As shown, reveal Figure 3 The horizontally positioned base 32 of the door opener 31 rotates toward the door panel 12 via the arm 322 and the pivot 321, allowing... Figure 3The base surface 320 shown covers the outer wall surface of the door panel 12, and the pair of keys 33 are inserted into the pair of lock holes of the door panel 12 to unlock the door panel 12.

[0070] Please continue reading Figure 10 As shown, reveal Figure 9 The base 32 relies on Figure 3 The paired keys 33 are embedded in the door panel 12, so that the door panel 12 follows the reset swing of the base 32 to the horizontal position, and then disengages from the housing 11, and exposes the inner wall surface of the door panel 12, which is equipped with the air-stopping rubber strip 120 and the row of guide ribs 121, so that the door panel 12 on the housing 11 can be opened.

[0071] In addition, please refer to other relevant documents. Figure 11 The base 32 of the door opener 31 (or unlocker 30) can drive the door panel 12 to rotate to a vertical position via the arm 322 and the pivot 321 (non-). Figure 7 (as shown in the horizontal configuration) so that the inner wall surface of the door panel 12, which is equipped with the air-stopping rubber strip 120 and the row of guide ribs 121, can be exposed to the outside, so as to complete the opening of the door panel 12 on the housing 11.

[0072] Step S20: Use the two end faces of the handle to grip and place the housing and door panel respectively.

[0073] Please see Figure 12 Steps (a) to (g) are shown in sequence, revealing the execution content of this step, wherein the action of the taking hand 40 is indicated by a dashed solid arrow and the order of steps (a) to (g) is indicated by a solid hollow arrow.

[0074] First, as shown in step (a), it is revealed that when the material box 10 is unlocked by the door opener 31 (or unlocker 30) to the position as shown in step (a), the material box 10 is opened to the position as shown in step (b). Figure 10 or Figure 11 After the shell 11 and the door plate 12 are separated as shown, Figure 2 The robotic arm 27 shown can move the handle 40 to the feed port 211 (or loading port 21), and clamp the flange 113 on the housing 11 using the first gripper 44. Continuing as shown in step (b), the handle 40 is then used to lift the housing 11 away from the loading port 21 using the first gripper 44; subsequently, with... Figure 10Taking the door panel 12 in a horizontal position as an example, as shown in step (c), the handle will rotate 180 degrees, causing the second gripper 45 on the handle 40 to face downwards and align with the door panel 12 on the base 32; continuing as in step (d), the handle 40 then moves downwards, and the second gripper 45 clamps the opposite ends 122 and 123 of the door panel 12, so that the two end faces of the handle 40 can respectively clamp the housing 11 and the door panel 12, thereby simultaneously transporting the housing 11 and the door panel 12 from the loading port 21 to the plurality of cleaning stations [as shown in steps (e) to (g)].

[0075] Step S30: Clean the housing and door panels of the cleaning machine.

[0076] Please merge Figure 2 and Figure 12 Step (e) is shown; where, Figure 2 The multiple cleaning machines 23 disclosed actually include at least one cleaning machine 231 for wet cleaning purposes as shown in step (e), and the handle 40 is capable of placing the housing 11 and the door panel 12 within the same cleaning machine 231; step (e) further discloses that the at least one cleaning machine 231 can actually be divided into a housing cleaning machine 231a specifically for cleaning the housing 11 and a door panel cleaning machine 231b specifically for cleaning the door panel 12, such that when the handle 40 simultaneously moves the housing 11 and the door panel 12 to the cleaning machine 231, it can first move to the housing cleaning machine 231a and place the housing 11 within the housing cleaning machine 231a by means of the first clamp 44 opening the clamp [as shown in step (e)], and then move to the door panel cleaning machine 231b and place the door panel 12 within the door panel cleaning machine 231b by means of the second clamp 45 opening the clamp [as shown in step (f)], so that the housing 11 and the door panel 12... It can be wet-cleaned in the cleaning machine 231 [as shown in step (g)]; wherein the robotic arm 27 can rotate the handle 40 by a necessary angle so that the handle 40 can place the housing 11 and the door panel 12 into the cleaning machine 231 one by one; wherein the housing cleaning machine 231a and the door panel cleaning machine 231b can be configured in stacked or separate slots.

[0077] also, Figure 2 The plurality of cleaning machines 23 shown also include at least one vacuum dryer 232. When there are multiple vacuum dryers 232, they can be stacked or separately arranged around the periphery of the robotic arm 27. The method by which the handle 40 moves and places the housing 11 and door panel 12 in the vacuum dryer can be analogous to the method by which the handle 40 moves and places the housing 11 and door panel 12 in the cleaning machine 231. Furthermore, after the housing 11 and door panel 12 have been cleaned in the cleaning machine 231, the handle 40 can individually pick up the housing 11 and door panel 12 from the cleaning machine 231 and move them to… Figure 2 The vacuum dryer 232 shown is placed inside, and so on, so that the handle 40 can be placed and gripped between multiple cleaning machines 23, so that the housing 11 and the door 12 can complete the predetermined cleaning process.

[0078] Step S40: Engage and lock the door panel on the housing.

[0079] Please refer back to steps (f) to (a) to see that after the cleaning process of the housing 11 and door panel 12 in step S30 is completed, the handle 40 can use the same method as in step S20 with the first gripper 44 and the second gripper 45 to grip the housing 11 and door panel 12 inside the cleaning machine 23 one by one, and transport them to... Figure 3 The discharge port 212 is shown; please refer to further details. Figure 13 The handle 40 is disclosed to place the housing 11 on the platform 210 of the discharge port 212, and to place the door panel 12 on the base 32 of the door closer 34 (or unlocker 30); please refer to the following. Figure 14 The door panel 12 is engaged with the opening 110 of the housing 11 by the drive of the base 32. The door closer 34 (or unlocker 30) and the pair of keys enable the door panel 12 and the housing 11 to lock together to form the material box 10 after the cleaning process is completed.

[0080] In addition to the above-described operation method, the present invention also includes a defect detection process of adding a material box after performing the above-described step S10, i.e., unlocking and opening the door piece 12 on the housing 11, and before performing the above-described step S20, i.e., the handle 40 gripping the housing 11 and the door piece 12; the defect detection process includes the steps of performing one step S11 and one step S12 (e.g. Figure 15 As shown). Wherein:

[0081] Step S11: Inspect the current condition characteristics of the housing and door panel.

[0082] like Figure 10 and Figure 15 As shown, in this step S11, the current condition characteristics of the housing 11 and the door panel 12 can be detected by one or more photosensitive coupling elements 50 suspended around the table surface 210 of the inlet port 211 (or loading port 21). Specifically, when the loading port 21 is divided into the inlet port 211 and the outlet port 212, the photosensitive coupling element 50 is suspended in the inlet port 211; when the loading port 21 has both inlet and outlet functions, the photosensitive coupling element 50 is suspended in the loading port 21. Before performing the cleaning process, the current condition characteristics of the housing 11 and the door panel 12 are detected to determine the quality of the housing 11 and the door panel 12.

[0083] exist Figure 10 In the illustrated example, when the photosensitive coupling element 50 includes the first photosensitive coupling element 51 and the second photosensitive coupling element 52, the fixed first photosensitive coupling element 51 can capture an image of the inner wall surface of the housing 11 with internal guide ribs 112 at the opening 110 of the housing 11. The second photosensitive coupling element 52, which can move linearly in the horizontal direction, can move to the position corresponding to the inner wall surface of the door panel 12 where the air-stopping strip 120 and the row of guide ribs 121 are arranged to capture an image. These images together serve as the internal condition feature N1 of the inspected material box 10 (composed of the image of the inner end face of the material box). Simultaneously, the second photosensitive coupling element 52 can also move to the top surface area of ​​the housing 11, including the flange 113, to capture an image, which serves as the external condition feature N2 of the inspected material box 10.

[0084] Furthermore, in Figure 10 In the example shown, the first photosensitive coupling element 51 can be implemented in a fixed manner or in a manner that moves linearly along the horizontal direction; the internal condition feature N1 of the material box 10 may also include an image captured by the first photosensitive coupling element 51 at the end edge position of the door panel 12, combined with the side view of the air-stopping strip 120, to determine whether the air-stopping strip 120 is damaged or detached. Furthermore, in Figure 7 In the example shown, the external condition feature N2 may also be included in Figure 3 In this state, the first photosensitive coupling element 51 captures an image of the outer wall surface with paired lock holes on the door panel 12, which, together with the top surface area image of the housing 11 including the flange 113, serves as the external condition feature N2 of the inspected material box 10.

[0085] exist Figure 11 In the example shown, when the photosensitive coupling element 50 includes the first photosensitive coupling element 51 and the second photosensitive coupling element 52, the first photosensitive coupling element 51 can sequentially align with the opening 110 of the housing 11 to capture images of the inner wall surface of the housing 11 with internal guide ribs 112 and the inner wall surface of the door panel 12 with air-stopping strips 120 and row-shaped guide ribs 121, which together serve as the internal condition feature N1 of the material box 10 under inspection. Simultaneously, the movable or fixed second photosensitive coupling element 52 can also align with the top surface area of ​​the housing 11, including the flange 113, to capture images, which serve as the external condition feature N2 of the material box 10 under inspection. Similarly, in Figure 8 In the example shown, the external condition feature N2 may also be included in Figure 3In this state, the first photosensitive coupling element 51 captures an image of the outer wall surface with paired lock holes on the door panel 12, which, together with the top surface image of the housing 11 including the flange 113 and the screw 114, serves as the external condition feature N2 of the inspected material box 10.

[0086] See also Figure 16 As shown, the housing 11, which is placed on the platform 210 of the feed port 211 and has its door 12 opened, is exposed. Figure 8 The first photosensitive coupling element 51 can capture an image of the back wall of the housing 11 by means of a rotating table (not shown) additionally configured on the table 210, or by means of the robotic arm 27 in the cleaning zone station 20, to rotate or move the housing 11 by 180 degrees, so that the housing 11 can capture an image of the back wall of the housing 11 as part of the external condition feature N2 of the material box 10 under inspection, which is also within the scope of the present invention.

[0087] Furthermore, in a variant implementation, before unlocking the material box 10, the present invention can first detect multiple external condition features N2 of the housing 11 and the door panel 12 according to the above method, and compare the differences between the external condition features N2 and the external standard features S2, before unlocking and opening the door panel 12 on the housing 11, detecting multiple internal condition features N1 of the housing 11 and the door panel 12, and comparing the differences between the internal condition features N1 and the internal standard features S1.

[0088] Step S12: Compare and determine the location of defects in the material box.

[0089] This step utilizes a control unit (which can be made of an MCU, not shown) configured within the device to internally connect the standard features S (including internal standard features S1 and external standard features S2) of the housing 11 and the door plate 12. The control unit also receives the current status features N (including internal current status features N1 and external current status features N2) detected in step S20 above, and compares the image features between the standard features S and the current status features N to determine if there are differences, and if there are errors in the image features exceeding the limit. When the error exceeds the predetermined allowable range, the location of the error is determined to be the defective location of the material box 10, and it is known that the defective location is located on the inner wall surface and / or outer wall surface of the shell 11 and / or the door panel 12. Then, the shell 11 and door panel 12 belonging to good products and the shell 11 and door panel 12 belonging to defective products are determined and summarized, thereby completing the material box defect detection process of the present invention, so that when the aforementioned step S20 is subsequently executed, the handle 40 can carry the shell 11 and door panel 12 belonging to good products for cleaning.

[0090] Since the execution processes of steps S10, S11 to S20 are all performed at the loading port 21 (or feeding port 211), and the robotic arm 27 in the cleaning station 20 is only responsible for transporting the unlocked and inspected housing 11 and door 12 into and out of the cleaning machines 22, 23, and 24 for wet cleaning and vacuum drying, the execution process of the present invention can significantly reduce the operation time of the robotic arm 27 in the cleaning station 20 to transport the housing 11 and door 12 for sequential cleaning.

[0091] Furthermore, the housing 11 or door piece 12 that is identified as defective by defect detection at the loading port 21 (or feed port 211) can be directly removed by the overhead crane or other automated equipment to eliminate the defective products from the production line. This avoids the robotic arm 27 in the cleaning station 20 from picking up the housing 11 or door piece 12 that already has defects for cleaning, thus greatly improving the efficiency of the cleaning material box in detecting defective products.

[0092] In a modified implementation, the execution of steps S11 to S12 can also be performed at the discharge port 212. This includes situations where, before the door closer 34 (or unlocker 30) has engaged the door panel 12 to lock onto the housing 11, the aforementioned photosensitive coupling element 50 (including the first photosensitive coupling element 51 and the second photosensitive coupling element 52) ​​executes step S11, i.e., detecting the current condition characteristics N (including internal condition characteristics N1 and external condition characteristics N2) of the housing 11 and the door panel 12 after cleaning. Then, the control unit executes step S12, i.e., comparing and determining the defect location of the material box to complete the material box defect detection process of the present invention. Only then does the door closer 34 (or unlocker 30) engage the door panel 12 to lock onto the housing 11 (e.g., ...). Figure 11 The cleaning process involves assembling the cleaned material box 10. Accordingly, the overhead crane or other automated equipment can automatically identify whether the material box 10 on the discharge port 212 is a good or defective product, and then transport it to an appropriate position so that the material box 10 leaves the cleaning station 20.
