Technical Field

[0001] This utility model relates to the field of chip auxiliary production equipment technology, and in particular to a material box cleaning device and a material box cleaning and sorting device. Background Technology

[0002] After being packaged by packaging equipment, chips are formed into wafers, with multiple chips mounted on a single wafer. To facilitate wafer transport, the wafers are stacked in a cassette, a box-shaped structure with openings at both ends in the horizontal direction. Multiple slots are provided on the two opposite inner sidewalls of the cassette, into which the opposite edges of the wafers are inserted. After packaging, the edges of the wafers may accumulate dust and debris, and the cassettes also tend to accumulate dust over time. This dust and debris can affect the normal loading and unloading of wafers and may impact chip quality. Therefore, the cassettes need to be cleaned. Current technology involves manually cleaning each cassette individually, which is inefficient. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Please see Figure 1 This utility model, in a preferred embodiment, provides a box cleaning and sorting device, comprising a box cleaning device 1, a sorting device 2, an isolation device 3, and a conveying device 4. The box cleaning device 1 is used to clean the boxes. The isolation device 3 is located longitudinally (Y) between the box cleaning device 1 and the sorting device 2, separating them to ensure cleanliness at the sorting device 2. The sorting device 2 is used to sort the boxes by height. Figure 2As shown, multiple material boxes 902 of the same specification are arranged longitudinally Y in the same holding basket 901. The openings at both ends of the multiple material boxes 902 are transversely X, so as to facilitate the simultaneous cleaning of multiple material boxes 902 of the same specification and improve cleaning efficiency. The conveying device 4 passes through the material box cleaning device 1 and the isolation device 3 and extends to the sorting device 2. After the holding basket 901 is placed on the conveying device 4, the conveying device 4 can drive the holding basket 901 containing the material boxes 902 to move longitudinally Y, so that it is transported through the material box cleaning device 1 and through the isolation device 3 to the sorting device 2.

[0021] like Figure 3 , Figure 4 and Figure 5 As shown, the material box cleaning device 1 includes a housing 11, a height detection mechanism 12, a straightening mechanism 13, a lifting mechanism, and an airflow mechanism 14; the conveying device 4 extends into the housing 11; the height detection mechanism 12, the straightening mechanism 13, the lifting mechanism, and the airflow mechanism 14 are all disposed within the housing 11. The height detection mechanism 12 is used to detect the height of the material box 902; the straightening mechanism 13 is movably disposed within the housing 11 along the vertical Z direction to straighten multiple material boxes 902; the lifting mechanism is used to lift multiple material boxes so that the airflow mechanism 14 can align and blow air; the airflow mechanism 14 is used to blow out and suck away the ash and slag inside the material box 902.

[0022] After the basket 901 containing multiple material boxes 902 moves into the housing 11 driven by the conveying device 4, the height detection mechanism 12 detects the height of the material boxes 902, and then the alignment mechanism 13 aligns the multiple material boxes 902 in the horizontal X direction. The lifting mechanism lifts the multiple material boxes 902, and the airflow mechanism 14 blows out and sucks away the ash and slag in the material boxes 902, thus completing the cleaning of the multiple material boxes 902.

[0023] like Figure 6 , Figure 7 As shown, the height detection mechanism 12 includes a fixed plate 121, a lifting drive assembly 122, and a pressing assembly 123. The fixed plate 121 is fixed to the housing 11. The pressing assembly 123 is movably disposed below the fixed plate 121 along the vertical Z direction. The lifting drive assembly 122 is disposed on the fixed plate 121 and connected to the pressing assembly 123, and is used to drive the pressing assembly 123 to move up and down, so that the pressing assembly 123 abuts against the top surface of the material box 902, and the height specification of the material box 902 is determined according to the downward movement distance of the pressing assembly 123. The height of the material box 902 can be accurately detected by the pressing assembly 123, avoiding the gaps between the material boxes 902 from affecting the detection accuracy. Of course, in other embodiments, the height detection mechanism 12 can also be an infrared detector, a distance detector, or other mechanisms that can detect the height of the material box 902.

[0024] In this embodiment, the lifting drive assembly 122 is positioned above the fixed plate 121 to keep it away from the material box 902, thus preventing ash and slag from entering the lifting drive assembly 122 and affecting its operation.

[0025] like Figure 8 As shown, the pressing assembly 123 includes a pressing body 1231, a buffer 1232 and a detection component 1233. The pressing body 1231 is connected to the lifting drive assembly 122 so that the entire pressing assembly 123 can be moved up and down under the drive of the lifting drive assembly 122.

[0026] The buffer 1232 is connected below the pressing body 1231 and is used to abut against the material box 902 to prevent damage caused by rigid contact between the pressing assembly 123 and the material box 902. In this embodiment, the buffer 1232 is a sponge.

[0027] The detection element 1233 is movably connected to the pressing body 1231 along the vertical Z direction. In this embodiment, the detection element 1233 is disposed on the horizontal X side of the pressing body 1231 and the buffer 1232. There are two detection elements 1233, which are respectively disposed on the horizontal X sides of the pressing body 1231 to ensure detection accuracy.

[0028] The detection element 1233 includes a contact plate 12331 and a guide post 12332. The contact plate 12331 is horizontally arranged and is an elongated strip along the longitudinal direction Y, allowing it to contact multiple material boxes simultaneously. The guide post 12332 is arranged along the vertical direction Z, with its bottom end connected to the top surface of the contact plate 12331. The top end of the guide post 12332 slides in conjunction with the pressing body 1231 along the vertical direction Z, enabling the detection element 1233 to move along the vertical direction Z. In this embodiment, there can be two or more guide posts 12332 arranged along the longitudinal direction Y to ensure the stability and reliability of the detection element 1233's movement along the vertical direction Z.

[0029] A detector 12311 is provided on the pressing body 1231. The detector 12311 is electrically connected to the lifting drive assembly 122. The detector 12311 is used to monitor the position of the detection element 1233 in order to control the operation of the lifting drive assembly 122. In this embodiment, the detector 12311 is located on the lateral X-side of the pressing body 1231, corresponding to the top end of the guide post 12332. By monitoring the position of the top end of the guide post 12332, the overall position of the detection element 1233 is monitored.

[0030] The bottom surface of the contact plate 12331 is located between the top and bottom surfaces of the buffer 1232. The lifting drive assembly 122 drives the pressing assembly 123 downwards, causing the buffer 1232 to abut against the material box 902. After the buffer 1232 is compressed to a certain extent, the contact plate 12331 abuts against the material box 902. As the pressing assembly 123 continues to move downwards, the detection element 1233 moves upwards relative to the pressing body 1231. The detector 12311 can detect the movement of the top of the guide column 12332 relative to the pressing body 1231, thus detecting that the pressing is complete. The lifting drive assembly 122 then stops driving the pressing assembly 123 downwards to avoid excessive downward movement. At this point, the height of the discharge box 902 can be determined based on the downward movement distance of the pressing assembly 123, thereby determining the specifications of the discharge box 902.

[0031] A connecting block 12312 is provided on the transverse X-side of the pressing body 1231. The connecting block 12312 is provided with a connecting hole. The top end of the guide post 12332 is movably inserted through the connecting hole along the vertical Z-direction to achieve a sliding fit between the guide post 12332 and the pressing body 1231. A compression spring (not shown in the figure) is sleeved on the guide post 12332. The two ends of the compression spring abut against the connecting block 12312 and the contact plate 12331 respectively. The compression spring can help the contact plate 12331 return to its initial state.

[0032] like Figure 6 and Figure 7 As shown, the lifting drive assembly 122 includes a lifting plate 1221 and a lifting drive component 1222. A pressing assembly 123 is connected to the bottom of the lifting plate 1221. The lifting plate 1221 is vertically movable along the Z-axis to move together with the pressing assembly 123. The lifting plate 1221 is horizontally positioned and has multiple lifting columns 1223. Mounting plates 1224 are mounted on the top of each lifting column 1223 to ensure the relative positions of the columns are reliably fixed. Multiple linear bearings are mounted on the mounting plate 121, and the lifting columns 1223 pass through these bearings to ensure the stability of the lifting plate 1221's lifting movement.

[0033] The lifting drive component 1222 is connected to the lifting plate 1221 to drive the lifting plate 1221 and the pressing assembly 123 to rise and fall together. In this embodiment, the lifting drive component 1222 includes a motor, a lead screw, and a nut. The motor is mounted on the mounting plate 1224, the lead screw is arranged vertically in the Z direction, and its two ends are rotatably connected to the lifting plate 1221 and the mounting plate 1224, respectively. The nut is fixed to the fixing plate 121 and threadedly connected to the lead screw. Through the cooperation of the nut and the lead screw, the overall structure formed by the lifting plate 1221, the mounting plate 1224, and the multiple lifting columns 1223 can be moved up and down. Of course, in other embodiments, the lifting drive component 1222 can be a cylinder.

[0034] Combination Figure 6 , Figure 9 As shown, the alignment mechanism 13 is movably disposed within the housing 11 along the vertical Z direction to drive the lifting and lowering of multiple material boxes 902. The alignment mechanism 13 includes alignment components 131 and lateral movement components 132. The alignment components 131 are arranged in two sets along the horizontal X direction. The lateral movement components 132 are connected to the two alignment components 131 and are used to move the two alignment components 131 closer to each other or further apart along the horizontal X direction to align and grip the material boxes 902. When the two alignment components 131 move closer to each other, the material box 902 is aligned; when the two alignment components 131 move further apart, the material box 902 is released. The alignment mechanism 13 can achieve the alignment of multiple material boxes 902, resulting in a compact structure.

[0035] The lateral movement component 132 is connected to the lifting drive component 122, so that the alignment mechanism 13 can move up and down under the drive of the lifting drive component 122, thereby lifting multiple material boxes 902 from the holding basket 901 for subsequent dust removal operations. The lifting drive component 122 enables pressure detection and the lifting of multiple material boxes 902, reducing the number of driving components and lowering equipment costs. Of course, in other embodiments, other lifting drive components can be separately configured to drive the vertical Z-axis movement of the alignment mechanism 13.

[0036] More specifically, such as Figure 9 As shown, the lateral movement component 132 is disposed on the lifting plate 1221. The lateral movement component 132 includes a lateral movement motor 1321, a gear 1322, and two racks 1323. The lateral movement motor 1321 is located above the lifting plate 1221, and the gear 1322 and the two racks 1323 are located below the lifting plate 1221, resulting in a reasonable layout and compact structure. The gear 1322 is rotatably disposed about the vertical Z direction and is connected to the lateral movement motor 1321, so that it rotates under the drive of the lateral movement motor 1321. The gear 1322 meshes between the two racks 1323. Both racks 1323 are movably disposed along the lateral X direction and are respectively connected to the two leveling components 131. When the gear 1322 rotates, it can drive the two racks 1323 to move along the lateral X direction, thereby driving the two leveling components 131 to move along the lateral X direction.

[0037] Two leveling components 131 are located below the lifting plate 1221, and a linear guide mechanism is provided between them and the bottom surface of the lifting plate 1221 to ensure the stability and reliability of the two leveling components 131 moving laterally (X). The linear guide mechanism includes a guide block 134 and a guide rail 135. The guide rail 135 is set along the horizontal (X) direction on the bottom surface of the lifting plate 1221, and the guide block 134 is installed on the leveling component 131. The guide block 134 and the guide rail 135 slide together, thereby facilitating the horizontal (X) movement of the leveling component 131.

[0038] like Figure 9, Figure 10 , Figure 11 and Figure 12 As shown, the alignment assembly 131 includes a movable frame 1311 and a stop block 1315. The movable frame 1311 slides with the lifting plate 1221 along the transverse X direction, and a linear guide mechanism is disposed between the movable frame 1311 and the lifting plate 1221. The two movable frames 1311 are movably disposed along the transverse X direction and connected to the transverse moving assembly 132, so that the entire alignment assembly 131 can move along the transverse X direction under the drive of the transverse moving assembly 132. The stop block 1315 is disposed on the movable frame 1311 and is an elongated strip disposed along the longitudinal Y direction, used to abut against multiple material boxes 902 in the transverse X direction. When the stop block 1315 moves in the transverse direction and abuts against multiple material boxes 902, it can align the multiple material boxes 902 in the transverse X direction.

[0039] In one implementation, the pressing body is configured as a vacuum suction cup. When the pressing body contacts multiple material boxes, it can adsorb the multiple material boxes. When the lifting drive assembly moves the pressing body upward, it can lift the multiple material boxes. Therefore, the vacuum suction cup and the lifting drive assembly work together to form the lifting mechanism. When the buffer 1232 is made of sponge, it and the pressing body together form a sponge-type vacuum suction cup. When it contacts multiple material boxes, the vacuum suction cup is activated. The part in contact with the material boxes can generate suction, while the other parts can automatically close to prevent dust from being sucked in.

[0040] In one embodiment, the straightening component 131 is provided with a gripper 1312, which can be used to hook and connect with the material box and clamp the material box. When the lifting drive component drives the lateral movement component and the straightening component 131 to move upward, it can drive multiple material boxes to move upward, thereby lifting multiple material boxes. By using the gripper 1312 of the straightening mechanism in cooperation with the lifting drive component, a lifting mechanism for lifting multiple material boxes can be formed.

[0041] Furthermore, there can be multiple grippers 1312, which are arranged along the longitudinal direction Y and rotatably mounted on the movable frame 1311 around the longitudinal direction Y. Each gripper 1312 has a hook 13121 at its bottom, which is located on the side of the gripper 1312 facing another alignment component 131 and is used to hook onto the top wall of the material box 902. After the two sets of alignment components 131 move closer to each other, the hook 13121 can move to below the top wall of the material box 902.

[0042] When the two sets of alignment components 131 move closer to each other and the hook 13121 abuts against the side wall of the material box 902, the gripper 1312 rotates in the direction away from the material box 902 to avoid the hook 13121 rigidly contacting the side wall of the material box 902 and damaging the gripper 1312, thus ensuring operational reliability.

[0043] The hook 13121 is positioned below the bottom surface of the pressing component 123. When detecting the height of the material box 902, the two sets of aligning components 131 are in a state of distance from each other to avoid the position of the material box 902. After the pressing component 123 moves downward and abuts against the top surface of the material box 902, the height of the material box 902 is detected. The pressing component 123 and the aligning component 131 then move upward together a predetermined distance, so that the bottom of the aligning component 131 is just aligned with the top of the material box 902, so as to grasp the material box 902. The predetermined distance can be determined based on the distance between the bottom surface of the hook 13121 and the pressing component 123.

[0044] A magnetic suction element 1313 is provided on the movable frame 1311. The magnetic suction element 1313 magnetically engages with the gripper 1312, providing a force to the gripper 1312 that causes the hook portion 13121 to rotate toward another aligning component 131. Using the magnetic suction element 1313, the hook portion 13121 can be held in the gripping position, preventing the gripper 1312 from rotating even when not in contact with the material box 902 due to friction between the grippers 1312. This ensures that the hook portion 13121 is located below the top of the material box 902, improving gripping reliability. If the hook portion 13121 abuts against the side wall of the material box 902, the gripper 1312 rotates against the force of the magnetic suction element 1313. Of course, in other embodiments, the hook portion 13121 can also be held in the gripping position by the gravity of the gripper 1312 itself.

[0045] A rotating block 13122 is provided on the top of the gripper 1312, and the rotating block 13122 and the hook 13121 are located on the same side of the gripper 1312 in the transverse direction X. A rotating hole 13120 is provided on the rotating block 13122. A rotating shaft 1314 is provided on the moving frame 1311, and the rotating shaft 1314 is arranged in the longitudinal direction Y and passes through the rotating hole 13120 of each gripper 1312. Through the rotational engagement of the rotating hole 13120 and the rotating shaft 1314, the gripper 1312 can rotate around the longitudinal direction Y.

[0046] The magnetic suction component 1313 is located between the rotating block 13122 and the hook 13121 in the vertical Z direction, which makes the overall structure of the straightening component 131 compact, reduces the space occupied, and facilitates the magnetic attraction between the magnetic suction component 1313 and the gripper 1312.

[0047] The stop block 1315 is located on the side of the plurality of grippers 1312 opposite to another aligning assembly 131, and the stop block 1315 and the grippers 1312 are spaced apart. The stop block 1315 provides space for the rotation of the grippers 1312. The bottom of the stop block 1315 extends to the bottom of the hook portion 13121 and is used to abut against the plurality of material boxes 902 in the horizontal X direction to align the plurality of material boxes 902 in the horizontal X direction.

[0048] like Figure 12As shown, the stop block 1315 is provided with a receiving groove 13150. The upper end of the receiving groove 13150 and the side facing the gripper 1312 are both open. When the gripper 1312 is magnetically connected to the magnetic suction component 1313, the hook 13121 protrudes from the receiving groove 13150 to extend into the material box 902. The receiving groove 13150 facilitates the reception of the gripper 1312, and the bottom structure of the stop block 1315 is located below the hook 13121, preventing the hook 13121 from colliding with other objects and damaging the gripper 1312 during the downward movement of the multi-grip 1312 grasping mechanism. When the hook 13121 moves into the receiving groove 13150, the bottom structure of the stop block 1315 abuts against the multiple material boxes 902 in the horizontal X direction, thereby aligning the multiple material boxes 902 in the horizontal X direction using the stop block 1315 to facilitate subsequent sorting operations.

[0049] The gripper 1312 has a sheet-like structure with its thickness in the longitudinal Y direction, so that more grippers 1312 can be arranged in the longitudinal Y direction, thereby increasing the number of grippers 1312 and ensuring gripping reliability.

[0050] like Figure 5 As shown, the airflow mechanism 14 is housed within the casing 11, and includes a dust collection hopper 141, a dust collection box 142, a fan 143, and an air knife component 144. The dust collection hopper 141, dust collection box 142, and fan 143 are all located below the conveying device 4 and the aligning mechanism. The top opening of the dust collection hopper 141 faces upwards, and the bottom end of the dust collection hopper 141 is connected to the air inlet of the fan 143 via the dust collection box 142. The dust collection box 142 and the fan 143 are arranged longitudinally, and the air outlet of the fan 143 connects to the air knife component 144. Figure 6 As shown, there are two air knives 144, located on both sides of the horizontal X direction of the alignment mechanism 13, to form air knives facing the material box. In this embodiment, the air outlet is tilted downward and biased towards the middle of the horizontal X direction of the two air knives, so that the air is directed downward, which facilitates the entry of ash and slag into the dust collection hopper 141.

[0051] The blower 143 creates a circulating airflow within the casing, sequentially passing through the material box 902, dust hopper 141, dust collection box 142, blower 143, and air knife 144. This causes ash and slag to concentrate in the dust collection box 142, thus cleaning the material box. The holding basket 901 can have a perforated structure to prevent ash and slag from remaining inside.

[0052] Before the height of the material box 902 is detected, that is, before the pressing component 123 moves down, the airflow mechanism 14 is activated to perform slag removal operation, so as to avoid the straightening component 131 blocking the air knife component 144 and causing inadequate cleaning.

[0053] Combination Figure 1 , Figure 3As shown, the isolation device 3 includes an isolation wall 31 and an isolation channel 32. The isolation wall 31 can separate the material box cleaning device 1 and the sorting device 2 into two independent spaces, preventing ash and slag from entering the sorting device 2 and ensuring the cleanliness of the sorting device 2.

[0054] The isolation channel 32 passes through the isolation wall 31, and its two ends are connected to the material box cleaning device 1 and the sorting device 2 respectively. Both ends of the isolation channel 32 are equipped with isolation curtains 321 so that the basket 901 containing multiple cleaned material boxes 902 must pass through the isolation channel 32 and the two isolation curtains 321 before entering the sorting device 2, further ensuring the cleanliness of the sorting device 2.

[0055] The conveying device 4 passes through the material box cleaning device 1 and the isolation device 3 and extends to the sorting device 2. In this embodiment, the conveying device 4 includes a multi-segment conveying device 41, which is arranged along the longitudinal direction Y. A sensor is installed downstream of each segment conveying device 41 in the conveying direction. The sensor is used to monitor the position of the basket to control the operation of the next segment conveying device 41. When the basket 901 is conveyed to the downstream of the segment conveying device 41 in the conveying direction, the sensor detects the position of the basket 901, and the next segment conveying device 41 starts. The conveying device 4 operates in segments, saving energy and ensuring the conveying stability of each segment.

[0056] In this embodiment, as Figure 1 , Figure 4 As shown, there are two sub-conveying devices 41. The upstream sub-conveying device 41 is located outside the material box cleaning device 1, and the downstream sub-conveying device 41 is located partly inside the material box cleaning device 1 and partly inside the isolation device 3.

[0057] like Figure 2 As shown, the sub-conveying device 41 includes a conveying motor (not shown) and multiple conveying rollers 411. The multiple conveying rollers 411 are arranged at intervals along the longitudinal direction Y, and the axial direction of each conveying roller 411 is the transverse direction X. The conveying motor is driven by the multiple conveying rollers 411 to drive the conveying rollers 411 to rotate around their own axial direction. The gaps between the conveying rollers 411 allow the blown-off ash and slag to enter the dust collection hopper 141.

[0058] like Figure 13 and Figure 14 As shown, the sorting device 2 includes a collection mechanism 21 and a sorting mechanism 22. The collection mechanism 21 includes a multi-layer collection rack 211, which is arranged vertically along the Z-axis. Figure 15 and Figure 16As shown, the sorting mechanism 22 is located on one side of the collection mechanism 21. It includes a sorting frame 221, a vertical Z-drive assembly 222, and a pushing assembly 223. The sorting frame 221 is movably arranged along the vertical Z direction to carry the basket 901. The vertical Z-drive assembly 222 is connected to the sorting frame 221 and is used to drive the sorting frame 221 to move along the vertical Z direction. In this embodiment, a motor and a ball screw are used. The pushing assembly 223 is arranged on the sorting frame 221 and is used to push the basket 901 to the collection shelf 211. When the sorting rack 221 is aligned with the conveyor 4, the multiple boxes 902 that have been cleaned can move to the sorting rack 221 along with the basket 901. According to the height specifications of the boxes 902 detected in the previous cleaning operation, the vertical Z drive component 222 drives the sorting rack 221 to move vertically Z to the corresponding collection shelf 211. The push component 223 pushes the basket 901 onto the collection shelf 211 to sort the boxes 902 to the corresponding collection shelf 211 according to their specifications.

[0059] like Figure 13 and Figure 14 As shown, each collection shelf 211 is elongated, with a sorting end 211a and a collection end 211b. The sorting end 211a is adjacent to the sorting mechanism 22. Each collection shelf 211 is inclined, and the height of the sorting end 211a is higher than that of the collection end 211b. Multiple rollers are provided on each collection shelf 211, arranged along the length of the collection shelf 211. The axial direction of the rollers is the width direction of the collection shelf 211, and the rollers are rotatably mounted on the collection shelf 211 around their own axial direction. When the basket 901 is pushed to the sorting end 211a, the basket 901 can slide along the length of the collection shelf 211 to the collection end 211b under the action of the rollers. The user can then remove the basket 901 from the collection end 211b for convenient use. The length of the collection shelf 211 can accommodate a large number of baskets 901.

[0060] In this embodiment, the length direction of the collection shelf 211 is horizontal (X), so that the user can take the holding basket 901 from the collection end 211b.

[0061] like Figure 15 and Figure 16 As shown, the sorting rack 221 is equipped with a sorting motor (not shown in the figure) and multiple sorting shafts 224. The multiple sorting shafts 224 are arranged at intervals along the longitudinal direction Y. The rotation of each sorting shaft 224 is set on the sorting rack 221, and the rotation axis is the transverse direction X. The sorting motor is driven by the multiple sorting shafts 224 so that the multiple sorting shafts 224 can rotate, thereby facilitating the transfer of the basket 901 from the conveyor 4 to the sorting rack 221.

[0062] The pushing assembly 223 includes a push-out drive 2231 and a push plate 2232. The push plate 2232 is movably disposed above the plurality of sorting shafts 224. The push-out drive 2231 is disposed on the sorting rack 221 and connected to the push plate 2232, and is used to push the basket to the collection mechanism. Preferably, the push-out drive 2231 is a motor coupled with a ball screw, but a cylinder can also be used.

[0063] In this embodiment, the collection mechanism 21 is located on the transverse X side of the sorting mechanism 22, so the basket needs to be pushed out along the transverse X. The push plate 2232 is movably arranged along the transverse X. The sorting rack 221 is also provided with a lifting assembly 225, which includes a lifting drive 2251, a lifting bracket 2252 and a plurality of roller strips 2253. The roller strips 2253 are arranged along the transverse X and are located between two adjacent sorting shafts 224. Each roller strip 2253 is provided with a plurality of rollers 2254. The plurality of rollers 2254 are arranged along the transverse X and rotate around the longitudinal Y. Roller strips 2253 are mounted on a lifting bracket 2252, which is located below the sorting shaft 224. A lifting drive unit 2251 is mounted on the sorting frame 221 and connected to the lifting bracket 2252 to drive the lifting bracket 2252 and multiple roller strips 2253 to move up and down, so that the top surface of the roller strips 2253 is lower or higher than the top surface of the sorting shaft 224.

[0064] When the multiple sorting shafts 224 rotate, the top surfaces of the multiple roller strips 2253 are lower than the top surfaces of the sorting shafts 224, allowing the basket to move longitudinally (Y) under the drive of the sorting shafts. When the basket is on the sorting shaft, the push drive 2251 drives the push bracket 2252 and the multiple roller strips 2253 to rise, so that the top surfaces of the multiple roller strips 2253 are higher than the top surfaces of the sorting shafts 224. At this time, the push plate 2232 moves laterally (X) under the drive of the push drive 2231, pushing the basket off the sorting rack and onto the collection mechanism. The roller strips 2253 facilitate the lateral (X) movement of the basket and prevent friction between the basket and the sorting shafts 224.

[0065] Each collection shelf 211 has a sorting end 211a equipped with a collection motor and multiple collection drive shafts. The collection motor is connected to the multiple collection drive shafts so that the basket 901 can smoothly enter the collection shelf 211.

[0066] The usage process of the material box cleaning and sorting equipment of this utility model is as follows.

[0067] In step S100, multiple material boxes 902 of the same specification are arranged in the same holding basket 901 along the longitudinal direction Y. The openings at both ends of the multiple material boxes 902 are horizontal X, so as to facilitate the subsequent clamping of the material boxes 902 at the openings.

[0068] In this step, after the material box 902 is placed in the holding basket 901, the holding basket 901 can be placed on the conveying device 4, and the holding basket 901 can be conveyed to the material box cleaning device 1 by the conveying device 4.

[0069] Step S200: Detect the height of the material box 902.

[0070] This step can be performed by the height detection mechanism 12 of the aforementioned material box cleaning device 1. Through this step, the specifications of the material box 902 can be determined, which facilitates the subsequent clamping and sorting of the material box 902.

[0071] In step S300, air is blown diagonally downwards from both sides of the horizontal X-shaped material box 902 to blow the ash out of the material box 902. Air is then drawn downwards from below the holding basket 901 to suck up and collect the ash, and the blowing and suction create a circulating airflow to achieve energy recycling.

[0072] The airflow mechanism 14 enables blowing and inhaling, thus achieving airflow recycling.

[0073] In step S400, the multiple material boxes 902 are lifted from the holding basket 901 and then placed back into the holding basket 901.

[0074] During the lifting and lowering of multiple material boxes 902, the material boxes 902 can be cleaned by the action of air knives, and the ash and slag in the holding basket 901 can be blown away, ensuring the cleanliness of the holding basket 901.

[0075] In this step, multiple material boxes 902 are positioned and aligned horizontally (X) using a lateral X-gripping method. Specifically, the aforementioned alignment mechanism 13 can be used to grip the multiple material boxes 902. During the lateral X-gripping process, the multiple material boxes 902 can be aligned horizontally (X), and the gripping and alignment are completed simultaneously, facilitating subsequent sorting. This step can be performed using the aforementioned alignment mechanism 13 to ensure that the multiple material boxes 902 are neatly arranged. In other embodiments, a separate alignment mechanism can also be provided. By pushing the material boxes 902 horizontally (X) to align them horizontally (X), a negative pressure adsorption mechanism can be used to lift the multiple material boxes 902 from the top.

[0076] Step S500: Sort the corresponding holding baskets 901 according to the height of the material box 902.

[0077] In this step, the holding basket 901 is conveyed to the sorting device 2, and the sorting device 2 sorts the boxes 902 according to their height. The holding baskets are then sorted to different height positions according to their height. In this embodiment, the aforementioned sorting mechanism 22 can be used to sort the boxes 902 to the collection shelves 211 located at different heights.

[0078] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those 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 defined in the claims.
