Description

Technical Field

[0001] This utility model relates to the field of electronic tray sorting technology, and in particular to an automatic electronic tray identification and sorting device. Background Technology

[0002] In the 3C industry's production process, electronic components must be sorted before being mounted onto the feeder of the pick-and-place machine. Before sorting, the label information on the electronic components must be identified and judged. Since this label information is usually formed by converting numbers and letters into complex content, resulting in a wide variety of electronic components, this undoubtedly increases the difficulty of the sorting work. Traditional electronic tray sorting primarily relies on manual labor, including manually identifying label information, picking up and placing trays, transporting trays, and moving between different workstations. However, this manual sorting method has several significant drawbacks: First, the judgment process lacks effective error-proofing mechanisms, making it prone to errors due to human negligence; second, human error is easily made in identifying complex label information, which in turn affects the accuracy of subsequent production processes; third, workers need to move around frequently during the sorting process, leading to high labor fatigue and potentially affecting their work performance over long periods; and fourth, due to limitations in manual operation speed and energy, sorting efficiency is low, making it difficult to meet the high-efficiency requirements of modern production. To address the drawbacks of manual sorting, some automated sorting equipment has emerged in the existing technology. These devices typically use camera recognition to identify electronic tray labels, specifically employing template comparison for sorting. However, this recognition method has significant limitations: when the electronic tray labels are blurry, the camera's recognition accuracy drops drastically, easily leading to misjudgments and preventing effective sorting of the electronic trays, severely impacting the continuity and reliability of the sorting process. Furthermore, existing automated sorting equipment often uses vacuum suction cups to grip electronic trays. However, due to differences in the design of electronic trays from different manufacturers—for example, the location of the notches varies, and the flatness of the trays is difficult to guarantee uniformly—vacuum suction cups struggle to adapt to trays of various sizes during gripping. This results in poor compatibility, making it impossible to perform gripping operations stably and reliably, further impacting the overall efficiency and stability of the sorting equipment.

[0003] Therefore, it is necessary to provide at least one automatic identification and sorting device for electronic trays to effectively and automatically identify and sort electronic trays. Utility Model Content

[0004] The purpose of this invention is to provide an automatic identification and sorting device for electronic trays, so as to improve the accuracy and efficiency of electronic tray sorting.

[0005] To achieve the above objectives, this utility model provides an automatic electronic tray identification and sorting device, including a frame, a material cart to be sorted, a tray lifting mechanism, a sorted material cart, a moving mechanism, an identification and sorting mechanism, and an electrical control device; the frame is provided with a sorting station and a sorted station; the material cart to be sorted is disposed at the sorting station, and the material cart to be sorted has several storage positions for stacking electronic trays; the tray lifting mechanism is disposed on the frame and located at the sorting station, and the tray lifting mechanism is used to drive the electronic trays located at the storage positions to be sorted to be lifted layer by layer; several sorted material carts are respectively disposed at the sorted station, and the sorted material carts have several... A sorted material storage position for stacking the electronic trays; a moving mechanism is mounted on the frame; an identification and sorting mechanism is mounted on the moving mechanism, and the moving mechanism and the identification and sorting mechanism are electrically connected to the electronic control device. The moving mechanism drives the identification and sorting mechanism to move, and the identification and sorting mechanism takes a picture of the electronic tray located at the top of the sorted material storage position and sends the image back to the electronic control device, so that the electronic control device controls the moving mechanism to move, thereby enabling the identification and sorting mechanism to transport and stack the photographed and identified electronic tray located at the top of the sorted material storage position to the corresponding sorted material storage position of the sorted material cart. Preferably, the sorting material cart is equipped with a sorting material support carrier that can be lifted and moved on it, and each sorting material storage position is arranged on the sorting material support carrier. The tray lifting mechanism lifts the electronic trays located at the sorting material storage positions by pushing the sorting material support carrier upward. Preferably, the tray lifting mechanism includes a tray lifting linear drive module and a tray lifting arm. The tray lifting linear drive module is mounted on the frame, and its output end is connected to the tray lifting arm. The tray lifting arm is driven to rise by the tray lifting linear drive module, thereby causing the tray lifting arm to lift the electronic tray located at the material storage position to be sorted layer by layer. Preferably, the sorted material cart is equipped with a sorted material support carrier, and each sorted material storage position is arranged on the sorted material support carrier. Preferably, the identification and sorting mechanism includes an identification component and a tray gripping component. The identification component and the tray gripping component are respectively disposed on the moving mechanism. The identification component and the tray gripping component are electrically connected to the electronic control device. The moving mechanism is used to drive the identification component and the tray gripping component to move. The identification component is used to take pictures and identify the electronic tray located at the top layer of the material storage position to be sorted and feed the results back to the electronic control device. The tray gripping component is used to grip and transport the photographed and identified electronic tray located at the top layer of the material storage position to be sorted.

The X-axis moving module is used to drive the Y-axis moving module, the Z-axis moving module, and the identification and sorting mechanism to move from the station to be sorted towards the sorted station along the X-axis direction. The Y-axis moving module is used to drive the Z-axis moving module and the identification and sorting mechanism to move along the Y-axis direction perpendicular to the X-axis direction. The Z-axis moving module is used to drive the tray gripping component to move along the Z-axis direction perpendicular to both the X-axis and the Y-axis directions. The axial movement causes the tray gripping component to move downward and grip the electronic tray. Preferably, the tray gripping assembly includes a gripping and pressing mounting component, a gripping and pressing drive module, a gripping floating module, a pressing floating elastic element, and a gripping module. The gripping and pressing mounting component is disposed on the moving mechanism. The gripping and pressing drive module is disposed on the gripping and pressing mounting component. The gripping floating module is movably mounted on the gripping and pressing mounting component, and the gripping and pressing mounting component is mounted on the gripping floating module and supports the gripping floating module. The pressing floating elastic element is disposed between the gripping floating module and the gripping and pressing mounting component along the moving direction of the gripping floating module. The gripping module is disposed on the gripping floating module and is used to grip the electronic tray. The gripping and pressing drive module drives the gripping floating module to descend, thereby causing the gripping module to press down on the upper surface of the electronic tray, causing the gripping floating module to retract upward and compress the pressing floating elastic element. Preferably, the gripping module includes a gripper cylinder and chuck fingers. The gripper cylinder is disposed on the gripping floating module, and a plurality of chuck fingers are respectively disposed on the output end of the gripper cylinder. The gripper cylinder drives the chuck fingers to move and open, so that the chuck fingers extend into the middle hole of the electronic material tray and clamp the electronic material tray. Preferably, the tray gripping assembly further includes a detection sensor, which is disposed on the gripping pressing mounting component and is used to detect whether the electronic tray on the gripping module has fallen off.

The electronic trays to be sorted are stacked on the material storage position of the material cart to be sorted. The tray lifting mechanism drives the electronic trays on the material storage position to be sorted to be lifted layer by layer, so that the identification and sorting mechanism can operate on the top electronic tray. The identification and sorting mechanism first takes a picture of the top electronic tray and identifies it, and feeds the identification information back to the electronic control device. The electronic control device controls the moving mechanism to move the identification and sorting mechanism according to the identification information, so that the identification and sorting mechanism can transport the identified electronic trays to the sorted material storage position of the corresponding sorted material cart and stack them on top of each other.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Please see Figures 1 to 6 The electronic tray automatic identification and sorting equipment 100 of this utility model includes a frame 1, a material cart 2 to be sorted, a tray lifting mechanism 3, a sorted material cart 4, a moving mechanism 5, an identification and sorting mechanism 6, and an electrical control device 7. The frame 1 is provided with a sorting station 11 and a sorted station 12. The material cart 2 to be sorted is located at the sorting station 11, and the material cart 2 has several storage positions 21 for stacking electronic trays 200. The tray lifting mechanism 3 is located on the frame 1 and at the sorting station 11, and is used to drive the electronic trays 200 located at the storage positions 21 to be sorted to be lifted layer by layer. Several sorted material carts 4 are respectively located at the sorted station 12. The machine is equipped with several sorted material storage positions 41 for stacking electronic trays 200. A moving mechanism 5 is mounted on the frame 1. An identification and sorting mechanism 6 is mounted on the moving mechanism 5. The moving mechanism 5 and the identification and sorting mechanism 6 are electrically connected to the electronic control device 7. The moving mechanism 5 is used to drive the identification and sorting mechanism 6 to move. The identification and sorting mechanism 6 is used to take pictures and identify the electronic trays 200 located on the top layer of the material storage position 21 to be sorted and feed the results back to the electronic control device 7. This allows the electronic control device 7 to control the moving mechanism 5 to move, so that the identification and sorting mechanism 6 can transport and stack the identified electronic trays 200 located on the top layer of the material storage position 21 to the sorted material storage position 41 of the corresponding sorted material cart 4.

[0018] During operation, the electronic trays 200 to be sorted are stacked one on top of the other on the sorting material storage positions 21 of the sorting material cart 2. The tray lifting mechanism 3 drives the electronic trays 200 on the sorting material storage positions 21 to be lifted layer by layer so that the identification and sorting mechanism 6 can operate on the top electronic tray 200. The moving mechanism 5 drives the identification and sorting mechanism 6 to move, so that the identification and sorting mechanism 6 first takes a picture of the top electronic tray 200 on one of the sorting material storage positions 21 and feeds back the identification information to the electronic control device 7. The electronic control device 7 controls the moving mechanism 5 to drive the identification and sorting mechanism 6 to move, so that the identification and sorting mechanism 6 can transport the identified electronic tray 200 to the sorted material storage position 41 of the corresponding sorted material cart 4 and stack them one on top of the other. Then, the moving mechanism 5 drives the identification and sorting mechanism 6 to move and reset, so that the identification and sorting mechanism 6 can identify and transport the top electronic tray 200 on the sorting material storage position 21 again, and so on. The entire process achieves automated sorting, eliminating the need for manual operation and effectively avoiding problems such as poor judgment, easy identification errors, high fatigue from walking, and low sorting efficiency that occur during manual sorting. The specific structure of the electronic control device 7 and its specific principle for controlling movement are well known to those skilled in the art, and therefore will not be elaborated upon here.

[0019] Please see Figure 3 and Figure 4 In one embodiment, the sorting material cart 2 is provided with a sorting material support carrier 22 that can be lifted and moved on it. Each sorting material storage position 21 is arranged on the sorting material support carrier 22. The tray lifting mechanism 3 lifts the sorting material support carrier 22 by pushing it up, so as to lift the electronic trays 200 located on the sorting material storage positions 21 layer by layer.

[0020] Specifically, in one embodiment, the material cart 2 to be sorted is provided with a plurality of support seats 23, each support seat 23 being supported on the bottom of the material carrier 22 to be sorted, and there is an insertion space 24 between the support seat 23 and the material cart 2 to be sorted for the insertion of the feeding tray lifting mechanism 3. The feeding tray lifting mechanism 3 can be inserted into the insertion space 24 and then lifted upward, thereby pushing the material carrier 22 to be sorted upward, so that the material carrier 22 to be sorted is disengaged from the support seat 23.

[0021] Specifically, in one embodiment, the material-to-be-sorted carrier 22 is provided with a plurality of first limiting rods 221 arranged at intervals, and each first limiting rod 221 surrounds a plurality of material-to-be-sorted storage positions 21 on the material-to-be-sorted carrier 22. The first limiting rods 221 limit the electronic tray 200 located in the material-to-be-sorted storage position 21 to prevent the electronic tray 200 from leaving the material-to-be-sorted storage position 21. Furthermore, the upper end of the first limiting rod 221 is provided with a first limiting plate 222, and the first limiting plate 222 is provided with a plurality of first limiting openings 222a. Each first limiting opening 222a limits the outer edge of the electronic tray 200 on each material storage position 21 to be sorted. The first limiting opening 222a can be arc-shaped or a circular hole with a notch. The first limiting plate 222 can further limit the electronic tray 200 located at the uppermost layer of the material storage position 21 to be sorted, but is not limited thereto.

[0022] Please see Figures 3 to 5 In one embodiment, the tray lifting mechanism 3 includes a tray lifting linear drive module 31 and a tray lifting arm 32. The tray lifting linear drive module 31 is mounted on the frame 1, and its output end is connected to the tray lifting arm 32. The tray lifting linear drive module 31 drives the tray lifting arm 32 to rise, thereby lifting the electronic trays 200 located on the material storage position 21 to be sorted layer by layer. Specifically, the tray lifting arm 32 is inserted into the insertion space 24. During the process of the tray lifting linear drive module 31 driving the tray lifting arm 32 to rise, the tray lifting arm 32 pushes the material support carrier 22 to rise, thereby lifting the electronic trays 200 located on the material storage position 21 to be sorted layer by layer. The tray lifting linear drive module 31 can be an existing linear drive module.

[0023] Please see Figure 2 and Figure 6 In one embodiment, the sorted material cart 4 is provided with a sorted material support carrier 42, and each sorted material storage position 41 is arranged on the sorted material support carrier 42.

[0024] Furthermore, in one embodiment, each sorted material storage position 41 is provided with a positioning rod 421 fixed to the sorted material support carrier 42. The positioning rod 421 is used for the electronic trays 200 to be sequentially fitted onto them. When the identification and sorting mechanism 6 transports the identified electronic trays 200 to the sorted material storage position 41 of the corresponding sorted material cart 4, the electronic trays 200 are located at the position corresponding to the positioning rods 421. When the identification and sorting mechanism 6 releases the electronic trays 200, the positioning rods 421 are inserted into the middle position of the electronic trays 200, so that the electronic trays 200 are fitted onto the positioning rods 421 and can move downward along the positioning rods 421 to the bottom position of the sorted material support carrier 42.

[0025] Furthermore, in one embodiment, the sorted material support carrier 42 is provided with a plurality of second limiting rods 422 arranged at intervals, and each second limiting rod 422 surrounds a plurality of sorted material storage positions 41 on the sorted material support carrier 42; the upper end of the second limiting rod 422 is provided with a second limiting plate 423, and the second limiting plate 423 is provided with a plurality of second limiting openings 423a, each second limiting opening 423a limiting the outer edge of the electronic tray 200 at each sorted material storage position 41. By setting the second limiting rods 422, the electronic tray 200 located on the sorted material storage position 41 is limited, preventing the electronic tray 200 from leaving the sorted material storage position 41; the second limiting plate 423, by setting the second limiting openings 423a, limits the outer edge of the electronic tray 200 entering the sorted material storage position 41.

[0026] Please see Figure 3 as well as Figures 7 to 9 In one embodiment, the identification and sorting mechanism 6 includes an identification component 61 and a tray gripping component 62. The identification component 61 and the tray gripping component 62 are respectively disposed on the moving mechanism 5. The identification component 61 and the tray gripping component 62 are respectively electrically connected to the electronic control device 7. The moving mechanism 5 is used to drive the identification component 61 and the tray gripping component 62 to move. The identification component 61 is used to take pictures and identify the electronic tray 200 located at the top layer of the material storage position 21 to be sorted and feed the results back to the electronic control device 7. The tray gripping component 62 is used to grip and transport the photographed and identified electronic tray 200 located at the top layer of the material storage position 21 to be sorted.

[0027] Specifically, the moving mechanism 5 includes an X-axis moving module 51, a Y-axis moving module 52, and a Z-axis moving module 53. The X-axis moving module 51 is mounted on the frame 1, the Y-axis moving module 52 is mounted on the X-axis moving module 51, the Z-axis moving module 53 is mounted on the Y-axis moving module 52, the identification component 61 is mounted on the Y-axis moving module 52, and the tray gripping component 62 is mounted on the Z-axis moving module 53. The X-axis moving module 51 is used to drive the Y-axis moving module. 52. The Z-axis moving module 53 and the identification and sorting mechanism 6 move from the sorting station 11 to the sorted station 12 along the X-axis. The Y-axis moving module 52 drives the Z-axis moving module 53 and the identification and sorting mechanism 6 to move along the Y-axis direction perpendicular to the X-axis direction. The Z-axis moving module 53 drives the tray gripping component 62 to move along the Z-axis direction perpendicular to both the X-axis and Y-axis directions, causing the tray gripping component 62 to move downwards and grip the electronic tray 200. The moving mechanism 5, by setting the X-axis moving module 51, the Y-axis moving module 52, and the Z-axis moving module 53, can drive the identification component 61 to move in the plane formed by the X-axis and Y-axis directions, and can drive the tray gripping component 62 to move in the plane formed by the X-axis and Y-axis directions and to move up and down in the Z-axis direction. More specifically, the moving mechanism 5 can first drive the identification component 61 to the corresponding material storage position 21 to be sorted via the X-axis moving module 51 and the Y-axis moving module 52. The Z-axis moving module 53 and the tray gripping component 62 also move accordingly. The identification component 61 first takes a picture of the electronic tray 200 located at the top of the material storage position 21 to be sorted and sends the image back to the electronic control device 7. Then, the electronic control device 7 controls the moving mechanism 5 to move according to the content of the picture and identification. The X-axis moving module 51, the Y-axis moving module 52 and the Z-axis moving module 53 of the moving mechanism 5 drive the material storage position 21 to the corresponding material storage position 21 to be sorted. The tray gripping component 62 moves to the position corresponding to the material storage location 21 to be sorted. The tray gripping component 62 then grips the uppermost electronic tray 200 that has been photographed and identified in the material storage location 21. The X-axis moving module 51, Y-axis moving module 52 and Z-axis moving module 53 of the moving mechanism 5 drive the tray gripping component 62 to move, so that the tray gripping component 62 transports the electronic tray 200 from the sorting station 11 to the sorted material storage location 41 of the sorted material cart 4 in the sorted station 12.

[0028] More specifically, the X-axis moving module 51 uses a single servo motor to synchronously drive two parallel moving length modules, thereby avoiding asynchronous movement on both sides during operation and thus preventing movement jamming. However, this is not a limitation.

[0029] Please see Figure 9 and Figure 10In one embodiment, the tray gripping assembly 62 includes a gripping and pressing mounting member 621, a gripping and pressing drive module 622, a gripping floating module 623, a pressing and floating elastic member 624, and a gripping module 625. The gripping and pressing mounting member 621 is disposed on the moving mechanism 5, the gripping and pressing drive module 622 is disposed on the gripping and pressing mounting member 621, and the gripping floating module 623 is movably mounted on the gripping and pressing mounting member 621. The gripping and pressing mounting member 621 passes through the gripping floating module 623 and supports the gripping floating module 623, pressing down. A floating elastic element 624 is positioned between the gripping floating module 623 and the gripping pressing mounting component 621 along the moving direction of the gripping floating module 623. A gripping module 625 is mounted on the gripping floating module 623 and is used to grip the electronic tray 200. The gripping floating module 623 is driven to descend by the gripping pressing drive module 622, causing the gripping module 625 to press down on the upper surface of the electronic tray 200. This causes the gripping floating module 623 to retract upwards and compress the pressing floating elastic element 624, thus ensuring that the electronic tray 200 is not damaged. The tray gripping assembly 62, by incorporating the gripping floating module 623 and the pressing floating elastic element 624, can be compatible with gripping electronic trays 200 of varying thicknesses or flatness.

[0030] Specifically, the gripping and pressing mounting component 621 is mounted on the Z-axis moving module 53.

[0031] Specifically, in one embodiment, the gripping module 625 includes a gripper cylinder 625a and chuck fingers 625b. The gripper cylinder 625a is disposed on the gripping floating module 623, and a plurality of chuck fingers 625b are respectively disposed on the output end of the gripper cylinder 625a. The gripper cylinder 625a drives the chuck fingers 625b to move and open, so that the chuck fingers 625b extend into the middle hole 201 of the electronic material tray 200 and clamp the electronic material tray 200. When the X-axis moving module 51, Y-axis moving module 52 and Z-axis moving module 53 of the moving mechanism 5 drive the material tray gripping component 62 to move to the corresponding storage position 21 of the material to be sorted, the gripping and pressing drive module 622 drives the gripping floating module 623 to descend, so as to drive the gripping module 625 to descend and press down on the upper surface of the electronic material tray 200. At the same time, the chuck finger 625b is inserted into the middle hole 201 of the electronic material tray 200, and the gripper cylinder 625a drives the chuck finger 625b to move and open, so that the chuck finger 625b grips the electronic material tray 200, thereby realizing the gripping of the electronic material tray 200. When the tray gripping assembly 62 transports the electronic tray 200 to the sorted material storage position 41 of the corresponding sorted material cart 4 in the sorted station 12, the gripper cylinder 625a drives the chuck fingers 625b to move and retract, thereby releasing the electronic tray 200 into the sorted material storage position 41 of the sorted material cart 4. By setting the chuck fingers 625b, the gripping module 625 can accommodate electronic trays 200 with various apertures, while also ensuring stability during transport.

[0032] Furthermore, in one embodiment, the tray gripping assembly 62 further includes a detection sensor 626, which is disposed on the gripping pressing mounting member 621. The detection sensor 626 is used to detect whether the electronic tray 200 on the gripping module 625 has fallen off.

[0033] Please see Figure 8 In one embodiment, the identification component 61 employs a character image recognition structure. The identification component 61 is used to photograph and recognize characters on the labels of the electronic tray 200 located at the top layer of the material storage position 21, and then feeds the character content back to the electronic control device 7. By adopting a character image recognition structure, the identification component 61 can utilize big data to improve the accuracy of recognition. The specific structure and principle of the identification component 61 are well known to those skilled in the art, and therefore will not be described in detail here. Combination Figures 1 to 10 The specific working principle of the electronic tray automatic identification and sorting equipment 100 of this utility model is as follows: The electronic trays 200 to be sorted are stacked one on top of the other on the sorting material storage positions 21 of the sorting material cart 2. The tray lifting mechanism 3's tray lifting linear drive module 31 drives the tray lifting arm 32 to rise, which in turn pushes the sorting material support carrier 22 to rise, thereby driving the electronic trays 200 located on the sorting material storage positions 21 to be lifted layer by layer. The moving mechanism 5 first moves the identification component 61 to the corresponding storage position 21 of the material to be sorted via the X-axis moving module 51 and the Y-axis moving module 52. The Z-axis moving module 53 and the tray gripping component 62 also move accordingly. The identification component 61 first takes a picture of the electronic tray 200 located at the top of the storage position 21 of the material to be sorted and sends the image back to the electronic control device 7. Then, the electronic control device 7 controls the moving mechanism 5 to move according to the content of the picture and identification. The X-axis moving module 51, the Y-axis moving module 52 and the Z-axis moving module 53 of the moving mechanism 5 move the tray gripping component 62, so that the tray gripping component 62 moves to the position corresponding to the storage position 21 of the material to be sorted. The gripping and pressing drive module 622 of the tray gripping component 62 drives the gripping floating module 623 to descend, so as to drive the gripping module 625 to press down on the upper surface of the electronic tray 200, so that the gripping floating module... 623 retracts upward and compresses the downward floating elastic element 624. At the same time, the chuck finger 625b inserts into the middle hole 201 of the electronic material tray 200. The gripper cylinder 625a then drives the chuck finger 625b to move and open, so that the chuck finger 625b grips the electronic material tray 200, thereby grabbing the uppermost electronic material tray 200 that has been photographed and identified in the material storage position 21 to be sorted. The X-axis moving module 51, Y-axis moving module 52 and Z-axis moving module 53 of the moving mechanism 5 drive the material tray gripping component 62 to move, so that the material tray gripping component 62 transports the electronic material tray 200 from the sorting station 11 to the sorted material storage position 41 of the sorted material cart 4 in the sorted station 12. The gripper cylinder 625a drives the chuck finger 625b to move and retract, thereby releasing the electronic material tray 200 into the sorted material storage position 41 of the sorted material cart 4. The X-axis moving module 51, Y-axis moving module 52, and Z-axis moving module 53 of the moving mechanism 5 drive the identification and sorting mechanism 6 back to the sorting station 11. The identification component 61 then takes a picture of the electronic tray 200, which is located at the top of the material storage position 21, and the tray gripping component 62 grabs the electronic tray 200 at the top of the material storage position 21. The moving mechanism 5 then drives the tray gripping component 62 to move, so that the tray gripping component 62 transports the electronic tray 200 from the sorting station 11 to the sorted material storage position 41 of the sorted material cart 4 in the sorted station 12. This cycle continues.

[0034] In summary, the automatic electronic tray identification and sorting equipment 100 of this invention, through the combination of the identification and sorting mechanism 6 and the electronic control device 7, achieves automatic identification and judgment of the label information of the electronic tray 200, replacing the traditional manual identification method. This automated identification mechanism has stable logical judgment capabilities, effectively avoiding judgment errors caused by human negligence, significantly improving the reliability of the identification process, and forming an effective mistake-proof mechanism. Secondly, the moving mechanism 5 in the automatic electronic tray identification and sorting equipment 100 of this invention can drive the identification and sorting mechanism 6 to automatically move between the sorting station 11 and the sorted station 12, completing the picking, placing, and handling operations of the electronic tray 200. This eliminates the need for frequent movement by workers, significantly reducing the labor fatigue intensity of workers and improving the working environment. Furthermore, the electronic tray automatic identification and sorting equipment 100 of this utility model, by setting up a material cart 2 to be sorted, a tray lifting mechanism 3, and a sorted material cart 4, lifts the electronic trays 200 on the material storage position 21 layer by layer through the tray lifting mechanism 3. With the coordinated work of the identification and sorting mechanism 6 and the moving mechanism 5, continuous and batch sorting processing can be achieved, which greatly improves sorting efficiency and can meet the needs of modern production for high-efficiency operation. In addition, the tray gripping component 62 of this utility model, by setting up a gripping floating module 623 and a pressing floating elastic element 624, can be compatible with gripping electronic trays 200 with different thicknesses or unevenness, and can also ensure that the electronic trays 200 are not crushed when pressed down, thus achieving effective protection of the workpiece.

Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
