[0001] This invention relates to the field of material sorting, and more particularly to a disordered sorting device and a disordered sorting method. Background Technology

[0002] Circular trays are mainly used for winding carrier tape (which may contain electronic components), terminal tape, and thin metal strips. In existing technology, when circular trays are packed in boxes or when the corresponding equipment is not packed, they are not sorted, resulting in different types of trays being contained in the same box. Conventionally, the trays are manually removed from the box and sorted. If the downstream equipment requires a specific number of trays, the corresponding number must also be manually removed, which is very inconvenient and increases the workload for operators. Summary of the Invention

[0007] In the above technical solution, a base plate is also provided on the rod frame below the bracket. The base plate is slidably disposed on the rod frame. The rod frame is provided with a base plate driving mechanism. The base plate driving mechanism is configured to drive the base plate closer to or away from the connection between the bracket and the rod frame. The bottom of the rod is mounted on the base plate.

[0008] In the above technical solution, the product verification mechanism is a barcode scanning mechanism or an industrial camera.

[0009] In the above technical solution, the alignment mechanism includes a turntable and an industrial camera positioned directly above the turntable.

[0010] In the above technical solution, the alignment mechanism includes an alignment frame and a centering mechanism mounted on the alignment frame, wherein the centering mechanism is used for centering of the material tray.

[0011] In the above technical solution, the centering mechanism includes a base frame, a support plate, two sets of first alignment rods, two sets of second alignment rods, and alignment rod driving components. The bottom of the support plate is mounted on the base frame via uprights, and the base frame is mounted on the alignment frame. The bottom of the first alignment rod and the second alignment rod are slidably mounted on the base frame. The support plate is provided with a through groove facing the first alignment rod and the second alignment rod. The top of the first alignment rod and the second alignment rod pass through the through groove and are positioned above the support plate. The alignment rod driving member is configured to drive the first alignment rod and the second alignment rod to move, and to make the first alignment rod and the second alignment rod move closer to each other or further away from each other.

[0012] In the above technical solution, the base frame is provided with a slide rail, and a first connecting plate and a second connecting plate that are parallel to each other are slidably arranged on the slide rail. The bottoms of the two sets of first alignment rods are respectively installed on the first connecting plate at intervals, and the bottoms of the two sets of second alignment rods are respectively installed on the second connecting plate at intervals. The alignment rod driving component is configured to drive the first connecting plate and the second connecting plate to move closer to each other or further away from each other.

S4. During the process of the alignment mechanism confirming and / or positioning the position of the material tray, the label printer prints a label, the feeding mechanism picks up the printed label and affixes it to the material tray on the alignment mechanism, and after the label is affixed, the feeding mechanism picks up the label on the alignment mechanism and puts it into the material box of the storage mechanism.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: See Figure 1-5 As shown, a disordered sorting device includes: Feeding mechanism 1, which is used for conveying the material box; Product confirmation mechanism 2 is located above the feeding mechanism 1 and is used to confirm the information and / or position of the corresponding material tray in the material box; The buffer mechanism 3 is located next to the feeding mechanism 1 and is used to buffer the material tray in the material box; Alignment mechanism 4 is used to confirm and / or position the material tray; The material storage mechanism 5 is located beside the alignment mechanism 4 or the feeding mechanism 1 and is used for storing and / or conveying the material tray. Label printer 6, used for label printing; The material gripping mechanism 7 is located beside the feeding mechanism 1 and is used for gripping and / or releasing the material tray, and gripping and / or affixing labels.

[0018] In this invention, the feeding mechanism can be a conveyor belt, roller conveyor line, robot, or other conveying structure. In this embodiment, the feeding mechanism is a U-shaped conveyor line (which can be a U-shaped conveyor belt or a U-shaped roller conveyor line), to accommodate... Figure 1Taking the direction as an example, the feeding mechanism 1 includes a transverse conveyor line 11, a left conveyor line 12, and a right conveyor line 13 (of course, the feeding mechanism can also use a single transverse conveyor line, in which case the positions of other mechanisms can be adjusted, for example, the position of the alignment mechanism can be adjusted to another location without affecting the feeding mechanism from sending away the hopper containing the material tray that does not need to be placed). The left and right conveyor lines are perpendicular to the transverse conveyor line. The front end of the left conveyor line faces the rear left end of the transverse conveyor line, and the front end of the right conveyor line faces the rear right side of the transverse conveyor line. The left conveyor line conveys from back to front, and the transverse conveyor line conveys from left to right (the transverse conveyor line can also change its conveying direction, for example, by using inclined guide wheels for sorting). The conveyor line, being an existing structure, can change its conveying direction. For example, after the hopper is fed into the left end of the transverse conveyor line via the left conveyor line, it is first conveyed to the right end of the transverse conveyor line. Then, the transverse conveyor line changes its direction again, conveying the hopper backward onto the right conveyor line. Alternatively, the transverse conveyor line can only convey to the right (with a pusher at the front of the right end of the transverse conveyor line pushing the hopper backward onto the right conveyor line). The right conveyor line conveys from front to back. The product confirmation mechanism is located above the transverse conveyor line on the right, above the front end of the right conveyor line. The gripping mechanism is located at the front end of the transverse conveyor line. The buffer mechanism is located to the left of the gripping mechanism and in front of the left end of the transverse conveyor line. The alignment mechanism is located at the right end of the transverse conveyor line. The storage mechanism is located in front of the alignment mechanism. The label printer is located where the gripping mechanism can pick up the label, for example, between the gripping mechanism and the storage mechanism, or in front of the storage mechanism.

[0019] The present invention also provides a disordered sorting method, which applies the above-mentioned disordered sorting device, and the steps are as follows: S1. The feeding mechanism transports the material box containing the material tray to the area below the product confirmation mechanism; In this embodiment, the left conveyor line transports the hopper containing different trays forward to the transverse conveyor line, and the transverse conveyor line transports the hopper to the right end of the transverse conveyor line, which is directly below the product confirmation mechanism. The trays are generally stacked from bottom to top, and each tray has a barcode. S2. The product verification agency first verifies the information of the topmost tray; In this invention, the product verification mechanism is a barcode scanning mechanism or an industrial camera. Preferably, the product verification mechanism is an industrial camera. The industrial camera takes pictures of the product, which can determine the position of the tray and also photograph the barcode on it. In this invention, a controller is electrically connected to each mechanism to control the operation of each mechanism. The controller reads the barcode information to confirm whether the tray is the one that needs to be dispensed. A sensor can also be installed at the product verification mechanism to detect whether there is a hopper or tray there.

[0020] S3. If it is the material tray to be discharged, the material grabbing mechanism will grab the material tray from the material box and place it on the alignment mechanism for alignment; if it is not the material tray to be discharged, the material grabbing mechanism will first grab the material tray from the material box and place it on the buffer mechanism. During this process, the product verification mechanism takes photos to confirm the information and position of the top tray. The material handling mechanism uses a robotic arm, preferably a multi-axis robotic arm, to pick up the tray and place it on the alignment mechanism or the buffer mechanism. Then, the product verification mechanism continues to verify the information of the next tray and continues to process that tray using the robotic arm.

[0021] S4. During the process of the alignment mechanism confirming and / or positioning the position of the material tray, the label printer prints a label, the feeding mechanism picks up the printed label and affixes it to the material tray on the alignment mechanism, and after the label is affixed, the feeding mechanism picks up the label on the alignment mechanism and puts it into the material box of the storage mechanism. During this process, the alignment mechanism can center the tray to position it, or take a photo to confirm its position, facilitating the robot arm's gripping of the tray. The tray placed on the alignment mechanism is the required tray, so the label printer will print a label. The label contains information such as dispensing label information or corresponding dispensing information. The robot arm grips the label and affixes it to the tray, and then puts the labeled tray into the hopper of the storage mechanism (a hopper is placed on top of the storage mechanism to store the required trays).

[0022] S5. Repeat steps S3 and S4 until the number of material trays in the material storage mechanism's loading box is the required number of materials to be discharged. Then, the robot arm will grab the material trays on the buffer mechanism and put them back into the material box below the product confirmation mechanism, and send the material box below the product confirmation mechanism away through the feeding mechanism. For example, if a single shipment requires 5 trays of material A, and the hopper on the transverse conveyor line contains trays of types A, B, and C, and if there are more than 5 trays of material A in the hopper, 5 trays of material A will be removed and placed into the hopper of the feeding mechanism. Trays of material B and C, which were removed midway and placed on the buffer mechanism, will be picked up again and placed into the hopper on the transverse conveyor line, and then the hopper will be sent away via the right-side conveyor line. If there are fewer than 5 trays of material A in the hopper, trays of material B and C, which were removed midway and placed on the buffer mechanism, will be picked up again and placed into the hopper on the transverse conveyor line, and then the hopper will be sent away via the right-side conveyor line. At the same time, the hopper will wait for the left-side conveyor line to deliver the hopper containing trays to the transverse conveyor line for the robot to pick up, until the number of trays of material A in the hopper of the storage mechanism meets the requirements.

[0023] S6. The material bin containing the required number of trays for dispensing material is transported away from the storage mechanism by manual labor, a conveyor mechanism, or an AGV. Once the required number of trays are placed in the material bin on the storage mechanism, the material bin can be removed by manual labor, a conveyor mechanism, or an AGV and delivered to the appropriate location. The conveyor mechanism can be a conveyor line, and the storage mechanism can also be a conveyor line.

[0024] In this embodiment, the material gripping mechanism 7 includes a robotic arm 71, a material gripping component 72 and a label gripping component 73 disposed on the robotic arm. The material gripping component 72 is used to grip and release the material tray, and the label gripping component 73 is used to grip the labels printed on the label printer 6 and affix them to the material tray.

[0025] In this embodiment, the robotic arm is a multi-axis robotic arm, and the gripping component is either a clamping fixture or a suction cup fixture, selected according to different tray models. For example, if the tray is suitable for gripping, a clamping fixture is used; if the tray is suitable for suction cup adsorption, a suction cup fixture is used. In this invention, multiple sets of disordered sorting devices can be arranged side by side. For example, one set of disordered sorting devices uses a clamping fixture for gripping, while another set uses a suction cup fixture. This allows for sorting of different trays without the need to change the gripping component midway, improving the efficiency of disordered sorting.

[0026] The label gripping component preferably employs multiple suction cups. These suction cups adsorb labels printed by the label printer, and then press the labels onto the material tray to complete the label application. In this embodiment, the clamping fixture, suction cup fixture, and label gripping component are existing structures. More preferably, a proximity sensor and a material sensor are also provided beside the gripping component to detect whether the gripping component is approaching the material tray or whether it has successfully gripped the tray, preventing empty gripping.

[0027] See Figure 3 As shown, the buffer mechanism 3 includes a rod holder 31, a rod 32, a bracket 33, and a bracket drive mechanism 34. One side of the bracket 33 is vertically slidably mounted on the rod holder 31. The bracket 33 has a slot in the middle. The bracket drive mechanism 34 is configured to drive the bracket 33 to move vertically. The middle part of the rod 32 passes through the slot, and the bottom of the rod 32 is connected to the bottom of the rod holder 31.

[0028] In this embodiment, the bracket is a C-shaped or U-shaped structure with a rearward opening. The rear end of the slot is connected to the rear end face of the bracket. A vertical slide rail or vertical guide rod is provided on the rod support. The front end of the bracket is slidably connected to the vertical slide rail or vertical guide rod. The rod is set parallel to the vertical guide rod or vertical slide rail. The bracket drive mechanism adopts a combination of motor and lead screw. The lead screw is parallel to the vertical slide rail or vertical guide rod. Both ends of the lead screw are rotatably connected to the rod support. The motor is connected to one end of the lead screw, and the middle part of the lead screw is connected to the bracket. The motor drives the lead screw to rotate. When the lead screw rotates, it drives the bracket to move up and down along the vertical slide rail or vertical guide rod, so that the bracket is close to or away from the top of the rod. The bracket supports and adjusts the position of trays that require buffering. For example, when storing material, the bracket moves upward, its top plane aligning with the top plane of the connecting rod. The robotic arm picks up the tray and places it onto the connecting rod (the connecting rod is inserted into the hole in the center of the tray). The bottom of the tray rests against the top surface of the bracket. Then, the bracket moves downward, moving the tray downward as well, its top plane aligning with the top plane of the connecting rod. When the robotic arm needs to pick up other trays and place them on the connecting rod, the bracket moves downward by the thickness of one tray each time a tray is placed, until the bracket reaches the bottom, indicating that the connecting rod is full and can no longer buffer material. When retrieving material, the bracket rises by the thickness of one tray after the robotic arm has picked up and moved away, ensuring that the robotic arm can always pick up one tray, facilitating material buffering and retrieval. The slot does not affect the vertical movement of the bracket relative to the connecting rod. Furthermore, sensors will be installed on the rod frame, positioned above the rod, to detect the presence of material at that location. These sensors will work in conjunction with the bracket drive mechanism to control the raising and lowering of the bracket.

[0029] Of course, as another preferred embodiment, a base plate is also provided on the rod holder below the bracket. The base plate is slidably mounted on the rod holder, and the rod holder is provided with a base plate driving mechanism. The base plate driving mechanism is configured to drive the base plate closer to or further away from the connection between the bracket and the rod holder. The bottom of the rod is mounted on the base plate. In this embodiment, since different trays have different sizes, especially for some larger trays, if the distance between the rod and the side wall of the rod holder is too small, it is difficult to place the tray onto the rod (the rod holder has an L-shaped structure, including a bottom support frame and a vertical frame, the bottom of the vertical frame is connected to the top front end of the bottom support frame, and the rod is located at the front end of the vertical frame). Therefore, a base plate and a base plate drive mechanism are set up. A longitudinal slide rail is set at the bottom of the rod frame, and the bottom of the base plate slides on the longitudinal slide rail. The base plate drive mechanism can be a combination of a cylinder or a motor and a lead screw. For example, a combination of a motor and a lead screw is used, with the lead screw parallel to the side of the longitudinal slide rail. The motor drives the lead screw to rotate, and the lead screw is connected to the base plate. Through the rotation of the lead screw, the base plate is moved back and forth, making it closer to or away from the upright frame, thus making it suitable for material trays of different sizes and improving its applicability.

[0030] In this invention, the alignment mechanism has two structures: The first type includes a transfer platform and an industrial camera positioned directly above the transfer platform. If the material tray is picked up using a suction cup fixture, this structure is employed. The robotic arm suctions the tray and places it on the transfer platform. The industrial camera takes a picture to determine the tray's position. The robotic arm then picks up a label and attaches it to the tray. Finally, the suction cup fixture accurately picks up the tray and places it into the storage bin of the material storage mechanism.

[0031] The second structure: The alignment mechanism 4 includes an alignment frame 41 and a centering mechanism 42 mounted on the alignment frame 41. The centering mechanism 42 is used for centering the material tray.

[0032] If the material tray uses a clamping fixture, then this structure is adopted. The clamping method involves inserting the clamping fixture into the hole at the center of the material tray for external clamping. The robot first picks up the material tray from the transverse conveyor line and places it on the centering mechanism. The centering mechanism centers the material tray so that its center is in a fixed position (regardless of the size of the material tray, the center will be in the same position). The robot can then quickly, stably, and accurately pick up the material tray and place it into the storage bin of the material storage mechanism. This embodiment uses the second structure.

[0033] See Figure 5As shown, the centering mechanism 42 includes a base frame 421, a support plate 422, two sets of first alignment rods 423, two sets of second alignment rods 424, and alignment rod driving components. The four bottom corners of the support plate 422 are respectively mounted on the base frame 421 via uprights 425. The base frame 421 is mounted on the alignment frame 41. Preferably, sensors are also provided on the support plate to detect whether there is a material tray on the support plate.

[0034] The bottom of the first alignment rod 423 and the second alignment rod 424 are slidably mounted on the base frame 421. The support plate 422 is provided with a through groove 426 facing the first alignment rod 423 and the second alignment rod 424. The tops of the first alignment rod 423 and the second alignment rod 424 pass through the through groove 426 and are positioned above the support plate 422. The alignment rod driving member is configured to drive the first alignment rod 423 and the second alignment rod 424 to move, and to make the first alignment rod 423 and the second alignment rod 424 move closer to each other or further away from each other.

[0035] The base frame 421 is provided with a slide rail 427, on which a first connecting plate 428 and a second connecting plate 429 are slidably arranged. The slide rail, the first connecting plate and the second connecting plate are arranged on the base frame below the support plate. The alignment rod drive is also arranged on the base frame below the support plate. The bottoms of the two sets of first alignment rods 423 are respectively installed on the first connecting plate 428 at intervals, and the bottoms of the two sets of second alignment rods 424 are respectively installed on the second connecting plate 429 at intervals. The alignment rod drive is configured to drive the first connecting plate 428 and the second connecting plate 429 to move closer to each other or further away from each other.

[0036] In this embodiment, the support plate is provided with two parallel through slots arranged at intervals. The through slots are arranged laterally, and two sets of first alignment rods are arranged at intervals. Two sets of second alignment rods are also arranged at intervals and are located at the right ends of the two sets of first alignment rods. The first alignment rod at the front end is directly opposite the second alignment rod at the front end, and the first alignment rod at the rear end is directly opposite the second alignment rod at the rear end. The middle parts of the first alignment rod at the rear end and the second alignment rod at the front end are inserted into the through slot at the rear end, and the middle parts of the first alignment rod at the front end and the second alignment rod at the front end are inserted into the through slot at the front end.

[0037] The first connecting plate is located to the left of the second connecting plate. Two transverse sliding rails are used, spaced apart front to back. The front ends of both the first and second connecting plates are slidably connected to the front transverse sliding rails, and their rear ends are slidably connected to the rear transverse sliding rails. The bottoms of the two sets of first alignment rods are connected to the front and rear ends of the first connecting plate, respectively, and the bottoms of the two sets of second alignment rods are connected to the front and rear ends of the second connecting plate, respectively. The alignment rod driving mechanism includes a motor 431, a belt 432, and two pulleys 433. The two pulleys are spaced apart between the two transverse sliding rails. The belt is wound around the two pulleys, and the motor drives one of the pulleys to rotate, thus driving the belt to rotate. The first and second connecting plates are located between the two pulleys. The bottom of the first connecting plate is connected to the front end of the belt, and the bottom of the second connecting plate is connected to the rear end of the belt. Thus, when the motor drives the belt to rotate, the first and second connecting plates can simultaneously move closer to or further away from each other, thereby causing the two sets of first and second alignment rods to move closer to or further away from each other. When alignment is required, the first and second alignment rods move away from each other, and the tray is placed on the support plate between the four alignment rods. Then, the first and second connecting plates move closer together. At this time, the two sets of first alignment rods move to the right, and the two sets of second alignment rods move to the left. Since the tray has a circular structure, the four sets of alignment rods push the tray to the center, thus achieving the alignment. After alignment is completed, the first and second alignment rods can move away from each other without affecting the robot's two-way gripping of the tray. Of course, the alignment rod drive can also be other drive structures that can simultaneously move the first and second alignment rods closer or further apart.

10. A method for unordered sorting, characterized in that: The steps of using the disordered sorting device as described in any one of claims 1-9 are as follows: S1. The feeding mechanism transports the material box containing the material tray to the area below the product confirmation mechanism; S2. The product verification agency first verifies the information of the topmost tray; S3. If it is the material tray to be discharged, the material grabbing mechanism will grab the material tray from the material box and place it on the alignment mechanism for alignment; if it is not the material tray to be discharged, the material grabbing mechanism will first grab the material tray from the material box and place it on the buffer mechanism. S4. During the process of the alignment mechanism confirming and / or positioning the position of the material tray, the label printer prints a label, the feeding mechanism picks up the printed label and affixes it to the material tray on the alignment mechanism, and after the label is affixed, the feeding mechanism picks up the label on the alignment mechanism and puts it into the material box of the storage mechanism. S5. Repeat steps S3 and S4 until the number of material trays in the material storage mechanism's loading box is the required number of materials to be discharged. Then, the robot arm will grab the material trays on the buffer mechanism and put them back into the material box below the product confirmation mechanism, and send the material box below the product confirmation mechanism away through the feeding mechanism. S6. The material bins containing the required number of material trays for discharge are sent away by manual labor, a conveyor mechanism, or an AGV.
