[0037] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below with reference to the accompanying drawings in this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.

[0038] Refer toFigures 1-5 , the present utility model discloses a cartridge picking and placing device 1, which is used to pick up and place a cartridge 2. The cartridge 2 contains materials required for MiniLED production such as MiniLED chips. The cartridge 2 is composed of four adjacent surfaces that surround the materials from four adjacent directions. Identification information such as two-dimensional codes and one-dimensional codes is provided on the four surfaces of the cartridge 2.

[0039] The device includes a control module 11, a vision mechanism 12, a torque detection mechanism 13, a clamping mechanism 14, and a mounting bracket 15. Among them, the control module 11 is connected to the vision mechanism 12, the torque detection mechanism 13, and the clamping mechanism 14. The control module 11 is used to control the operation of each mechanism and obtain and identify the electrical signals fed back by each mechanism. The vision mechanism 12 is used to identify the identification information on the cartridge 2 and locate the position of the cartridge 2. The clamping mechanism 14 is used to pick up the cartridge 2. The torque detection mechanism 13 detects the weight of the cartridge 2 picked up by the clamping mechanism 14. The mounting bracket 15 provides a mounting position for each mechanism. The vision mechanism 12, the torque detection mechanism 13, and the clamping mechanism 14 are arranged on the mounting bracket 15. The mounting bracket 15 is respectively connected to the vision mechanism 12, the detection mechanism, and the clamping mechanism 14.

[0040] Specifically, the mounting bracket 15 includes a first mounting plate 151 and a second mounting plate 152. The first mounting plate 151 is connected to the second mounting plate 152, and the first mounting plate 151 and the second mounting plate 152 are vertically arranged. The clamping mechanism 14 is installed below the second mounting plate 152, the torque detection mechanism 13 is installed above the second mounting plate 152, and the vision mechanism 12 is installed on the first mounting plate 151. The upper part of the torque detection mechanism 13 is connected to a conveying mechanism such as a robotic arm or an AGV robot. In addition, the torque detection mechanism 13 is a torque sensor. The torque detection mechanism 13 obtains the weight of the currently picked-up cartridge 2. When the detected weight exceeds a predetermined value, it feeds back an electrical signal to the control module 11. The control module 11 issues an alarm message and stops the picking-up action and subsequent actions. By using the device to pick up the cartridge, it can liberate human hands, and operations such as picking up and moving the cartridge during production can be handled without manual intervention, making the production process more automated.

[0041] It can be understood that when the device picks up the cartridge 2, it locates the position of the cartridge 2 to be picked up according to the information of the upper-level system, then identifies the identification information on the cartridge 2 through the vision mechanism 12, and finally picks up the cartridge 2 through the clamping mechanism 14. The torque detection mechanism 13 detects whether the picked-up cartridge is overweight by weight. In case of a situation where the picking-up fails due to problems such as overweight, it issues an alarm message and stops the operation of the device, waiting for manual intervention to avoid the device picking up overweight items and ensuring the normal operation of the device.

[0042] The mounting bracket 15 includes a mounting cover 153, the mounting cover 153 is connected to the first mounting plate 151, a receiving space is formed between the mounting cover 153 and the first mounting plate 151, the vision mechanism 12 is installed in this receiving space, and the mounting cover 153 is provided with an open opening in the shooting direction of the vision mechanism 12, facilitating the shooting and recognition by the vision mechanism 12.

[0043] The device includes a lighting source 16, the lighting source 16 is connected to the second mounting plate 152, and the light emitting direction of the lighting source 16 faces the clamping position of the clamping mechanism 14. Specifically, the lighting source 16 can provide a light source for the vision mechanism 12, and the lighting source 16 can illuminate the surface of the cartridge 2 that the clamping mechanism 14 needs to clamp, enabling the vision mechanism 12 to better capture and recognize the surface of the cartridge 2.

[0044] As an embodiment, the second mounting plate 152 is provided with an extension rod 1521, a clamping groove is provided at one end of the extension rod 1521 away from the body of the second mounting plate 152, the lighting source 16 is provided with a sliding groove 161, and a clamping member matching the clamping groove is provided at the notch of the sliding groove 161, enabling the lighting source 16 to be clamped on the second mounting plate 152. The elongation of the extension rod 1521 can make the lighting source 16 better approach the cartridge 2 clamped by the clamping mechanism 14.

[0045] The device includes a detector 17, the detector 17 is installed below the second mounting plate 152, and the detection port of the detector 17 faces the clamping position of the clamping mechanism 14. Specifically, the lighting source 16 is provided with a mounting groove 162 on the surface close to the clamping mechanism 14, the detector 17 is installed in the mounting groove 162, and the detector 17 detects whether the clamping mechanism 14 clamps the cartridge 2, and can also detect whether the cartridge 2 clamped by the clamping mechanism 14 drops.

[0046] The vision mechanism 12 includes a barcode scanner 121 and a camera 122, the camera 122 is connected to the second mounting plate 152, and the barcode scanner 121 is connected to the mounting shell. Specifically, the barcode scanner 121 can be used to scan the two-dimensional code or one-dimensional code on the cartridge 2 to read the relevant information of the cartridge 2, and the camera 122 is used to locate the current position of the cartridge 2. It adopts a 2x infrared laser, with a ranging range of 400mm - 1300mm and a resolution of up to 10fps@1920×1080, accurately obtaining the position where the current cartridge 2 is placed, avoiding subsequent clamping by the clamping mechanism 14 and scanning the information of the cartridge 2 by the barcode scanner 121.

[0047] The control module 11 is electrically connected to the vision mechanism 12 and the detection piece 17 respectively. The detection piece 17 can feedback to the control module 11 through an electrical signal whether the current material box 2 is being clamped by the clamping mechanism 14. When the clamping mechanism 14 drops during the clamping process or fails to clamp the material box 2, the detection piece 17 feeds back to the control module 11 through an electrical signal. Through the signal transmission between the control module 11 and the upper system and the sending of an alarm message, the current clamping action is stopped, and the current situation is transmitted through the signal for manual intervention. After manual reset, it accepts the instructions of the upper system again; before clamping the material box 2, the vision mechanism 12 first scans and identifies the material box 2 to obtain the information of the clamped material box 2 and the information of the materials loaded in the material box 2, so as to compare with the information in the upper system to ensure that the clamped material box 2 and the materials are the ones to be clamped.

[0048] The clamping mechanism 14 includes a clamping drive assembly 141 and two clamping assemblies 142. The clamping drive assembly 141 is connected to the second mounting plate 152, and the clamping drive assembly 141 is respectively connected to the two clamping assemblies 142.

[0049] Specifically, the clamping drive assembly 141 is used to drive the clamping assemblies 142 to operate. The two clamping assemblies 142 are used to apply forces to the two surfaces of the material box 2 to clamp the material box 2. The two clamping assemblies 142 can be moved closer or farther away by the clamping drive assembly 141.

[0050] The clamping drive assembly 141 includes a clamping drive part 1411 and a clamping drive block 1412. The clamping drive part 1411 is connected to the clamping drive block 1412. Specifically, the clamping drive part 1411 is a drive motor, and a chute matching the shape of the clamping drive block is provided on the clamping drive part. Under the action of the force applied by the clamping drive part 1411, the clamping drive block 1412 moves back and forth in the chute. The control module 11 can drive the operation of the clamping drive part 1411, so that the two clamping assemblies 142 can approach each other and apply a force to the material box 2 to achieve the purpose of clamping the material box 2.

[0051] The clamping component 142 includes a clamping slider 1421 and a clamping piece 1422. The clamping slider 1421 is connected to the clamping piece 1422, and the clamping slider 1421 is connected to the clamping drive block 1412. Specifically, the clamping slider 1421 is detachably connected to the clamping drive block 1412, and they are connected by fasteners. In addition, the clamping piece 1422 is detachably connected to the clamping slider 1421, and the two are connected by fasteners, so that the size of the current clamping slider 1421 and clamping piece 1422 can be selected according to the size of the clamped cartridge 2 to adapt to the size of the current cartridge 2, improve the clamping force on the cartridge 2, and better clamp the cartridge 2.

[0052] The clamping piece 1422 is provided with at least two protrusions 1424, and the protrusions 1424 are in contact with the surface of the cartridge 2. Specifically, slots are opened on the surface of the cartridge 2. Driven by the clamping slider 1421, the clamping piece 1422 clamps two opposite surfaces of the cartridge 2, and the protrusions 1424 can sink into the slots, so that the clamping piece 1422 is clamped with the cartridge 2, increasing the supporting force for the cartridge 2, preventing the cartridge 2 from falling due to excessive weight or other reasons during the clamping process, and preventing the materials loaded in the cartridge 2 from falling and being damaged.

[0053] Optionally, a flexible piece 1423 is provided on the surface of the clamping piece 1422 that contacts the cartridge 2. Specifically, the flexible piece 1423 can prevent the clamping piece 1422 from damaging the cartridge 2 when applying a force to the cartridge 2.
