[0026] An automatic ink cartridge dispensing device for printers includes a frame assembly 1, a feeding assembly 2, a transition assembly 3, a traverse assembly 4, a material picking and positioning assembly 5, a robotic arm dispensing assembly 6, a barcode reader assembly 7, and an AI event camera detection assembly 8. (See attached image) Figures 1 to 7 ,in:

[0027] Rack assembly 1, see Figure 2 The system includes a support frame, with a feeding hopper and a discharging hopper separated on the left and right sides at the bottom of the support frame. A base plate is installed at the bottom of both the feeding hopper and the discharging hopper, and a buffer plate is installed on the base plate of the discharging hopper. A sensor is installed in the discharging hopper to detect whether the empty ink cartridge tray is full. An installation panel 10 is installed on the support frame above the feeding hopper and the discharging hopper. The installation panel 10 has a feeding through hole 101 and a discharging through hole 102 at the corresponding positions of the feeding hopper and the discharging through hole 102, respectively, for the ink cartridge tray to pass through during feeding.

[0028] The feeding assembly 2 is located on one side of the feeding hopper and is used to lift the stacked multi-layer ink cartridge trays placed on it from the bottom of the feeding hopper to above the mounting panel 10. The transition assembly 3, the traverse assembly 4, the picking and positioning assembly 5, and the robotic arm delivery assembly 6 are respectively installed on the mounting panel 10. The transition assembly 3 is located on the adjacent mounting panels 10 above the feeding hopper and the unloading hopper and is used to separate the end of the top ink cartridge tray near the unloading hopper from the ink cartridge tray below it. The traverse assembly 4 is located on the mounting panel 10 on the side of the feeding hopper. The picking and positioning assembly 5 is located on the mounting panel 10 directly above the unloading hopper. The traverse assembly 4 is used to push the top ink cartridge tray to the position of the picking and positioning assembly 5 above the unloading hopper and to position the pushed ink cartridge tray. The robotic arm delivery assembly 6 is located on the support frame above the mounting panel 10 on the side of the picking and positioning assembly 5 and is used to transport the ink cartridges in the ink cartridge tray located at the picking and positioning assembly 5 one by one to the next process. The barcode reader assembly 7 is mounted on a support frame on one side above the mounting panel 10 where the robotic arm delivery assembly 6 is located. It is used to scan the serial number (S / N) of the ink cartridge picked up by the robotic arm delivery assembly 6. An AI event camera detection assembly 8 is installed at the top end of the support frame above the mounting panel 10 for safety detection, preventing operators from being within the work area. Among these:

[0029] The feeding assembly 2 includes a lead screw 11, linear guide rails 12, a hopper tray 13, and a lead screw motor 14. The lead screw 11 is vertically mounted on the outside of the feeding through hole 101 of the mounting panel in the feeding hopper. The lead screw 11 is mounted on a lead screw mounting base, and the lead screw motor 14 is mounted on the mounting panel 10. Vertical linear guide rails 12 are arranged parallel to each other on opposite sides of the lead screw 11. The hopper tray 13 is fixedly mounted on a slider on the lead screw nut and the linear guide rails 12. The lead screw motor 14 drives the lead screw 11 to rotate, causing the hopper tray 13 to move linearly along the linear guide rails 12 and the lead screw 11.

[0030] A positioning assembly is provided around the outer periphery of the material tray 13 in the feeding hopper. The positioning assembly includes guide vertical plates 15 fixedly mounted on the left and right sides of the feeding hopper, and a positioning pull plate 16, which slides along the mounting panel and the bottom of the support frame, located at the feeding inlet of the feeding hopper. The positioning pull plate 16 has a strip-like structure. Telescopic pull rods are symmetrically arranged below the mounting panel and above the bottom of the support frame. The upper and lower ends of the positioning pull plate 16 are fixedly mounted on the telescopic pull rods. A sensor is located at the bottom center of the telescopic pull rod to sense whether the positioning pull plate 16 is fully extended. A sensor for detecting the presence of an ink cartridge tray is located on one side of the bottom of the feeding hopper.

[0031] When loading materials, first pull the positioning plate 16 to one side of the loading port, and place the ink cartridge trays in a stacked manner from the loading port onto the material hopper tray 13. The left and right sides of the stacked ink cartridge trays are fixed by the guide vertical plates 15, and the back side is positioned by the linear guide rail. Then, pull the positioning plate 16 to the center position of the loading port. When it is pulled to the center position, the sensor senses the positioning plate 16 and indicates that the positioning plate 16 has been pulled to the center position.

[0032] Positioning baffles (20, 21) are provided on both the front and rear sides of the feeding through hole of the mounting panel 10. The positioning baffles (20, 21) and the feeding through hole of the mounting panel 10 form a feeding through hole for only the ink cartridge tray to pass through. The positioning baffle 20 has a notch, which isolates the lead screw and linear guide rail outside the feeding through hole for the ink cartridge tray, and the feeding tray plate 13 passes through the notch on the positioning baffle 20.

[0033] A photoelectric sensor transmitter 17 for detecting the presence of the ink cartridge tray, a photoelectric sensor 18 for detecting the position of the ink cartridge tray, and a photoelectric sensor receiver 19 for detecting the presence of the ink cartridge tray are provided on one side of the mounting panel 10 above the feeding hopper. The photoelectric sensor transmitter 17 and the photoelectric sensor receiver 19 are located diagonally opposite the feeding through-hole of the mounting panel 10 above the feeding hopper, and are used to detect whether the ink cartridge tray has risen to the correct position. The photoelectric sensor 18 for detecting the position of the ink cartridge tray detects whether there is an ink cartridge tray above the mounting panel 10 above the feeding hopper.

[0034] Transition component 3 includes a lifting component and an isolation component. The lifting component includes an L-shaped bracket 22 mounted on a mounting panel 10 above the end adjacent to the feeding bin and the unloading bin. The L-shaped bracket 22 is located on one side of the feeding through-hole for the ink cartridge tray on the mounting panel 10, and the lateral feature of the L-shaped bracket 22 is located above the feeding through-hole for the ink cartridge tray in the feeding bin. A first cylinder 23 is mounted on the L-shaped bracket 22, and a first cylinder push plate 24 is mounted above the L-shaped bracket 22. The first cylinder push plate 24 is fixedly connected to the telescopic rod of the first cylinder 23. A guide post 25 passes through a linear bearing 26 mounted on the L-shaped bracket 22. The upper end of the guide post 25 is fixedly connected to the first cylinder push plate 24, and the lower end is connected to a pneumatic gripper mounting plate. A pneumatic gripper 28 is mounted on the pneumatic gripper mounting plate, and the gripper 29 of the pneumatic gripper 28 is positioned downwards. When the first cylinder 23 retracts, it drives the first cylinder push plate 24 to move downward in a straight line, thereby driving the pneumatic gripper 28 to move downward, which is used to pick up the ink cartridge tray that has been loaded onto the mounting panel 10.

[0035] The isolation assembly includes a second cylinder 30 with a mounting panel 10 disposed between the loading through hole and the unloading through hole, linear guide rails spaced apart on the left and right sides of the second cylinder 30, and an isolation plate 31 disposed on the slider of the second cylinder 30 and the linear guide rails.

[0036] When the feeding assembly 2 feeds the ink cartridge tray to the mounting panel 10 above the feeding hopper, the sensor 18 senses the ink cartridge tray. The first cylinder 23 retracts, causing the pneumatic gripper 28's gripper 29 to move downwards and clamp one end of the ink cartridge tray. The first cylinder 23 extends, lifting the ink cartridge tray at one end of the lifting assembly to a position higher than the isolation plate 31. When the lifting is in place, the magnetic sensor of the first cylinder 23 senses that the first cylinder has reached its position. The second cylinder 30 then activates, causing the isolation plate 31 to extend upwards towards the feeding hopper, positioned below one end of the lifted ink cartridge tray. When the isolation plate 31 reaches its position, the gripper 29 of the pneumatic gripper 28 releases, and the lifted end of the ink cartridge tray falls down, positioned above the isolation plate 31.

[0037] The transverse movement assembly 4 is located on the other side of the loading through-hole of the mounting panel 10 opposite to the lead screw 11. The transverse movement assembly 4 includes a third cylinder 32, which is a rodless cylinder. A push plate 34 is connected to the slider 33. The push plate 34 is positioned above the loading through-hole of the ink cartridge tray on the mounting panel 10 above the loading bin, and can be moved to the side of the mounting panel 10 away from the unloading bin, opposite to the side of the loading through-hole of the ink cartridge tray. Sensors are respectively installed at both ends of the slider 33 of the third cylinder 32 in the direction of displacement.

[0038] When the lifted end of the ink cartridge tray falls onto the isolation plate 31, the front-end sensor responds, the third cylinder 32 moves, driving the pusher plate 34 to push the uppermost ink cartridge tray along the material tray support plate 13 and the isolation plate 13 to the material picking and positioning component 5 above the unloading hopper. The sensor 43 responds, the third cylinder 32 drives the pusher plate 34 to retract, and when the rear-end sensor detects this, the third cylinder 32 stops moving.

[0039] The material handling and positioning component 5 is arranged around the outer periphery of the material discharge through hole 102 on the mounting panel 10 above the material discharge hopper. It includes a positioning baffle 37 and two sets of positioning telescopic components. The positioning baffle 37 is located at one end of the mounting panel 10 in the pushing direction of the push plate 34 of the transverse moving component 4, specifically on the side of the mounting panel outside the material discharge through hole away from the material loading through hole. Fourth cylinders (38, 39) are respectively arranged on opposite sides of the positioning baffle 37. Telescopic support components are respectively arranged on both sides of the through hole adjacent to the side where the positioning baffle 37 is located. The support components include a horizontally arranged support plate 40 and a vertically arranged baffle 41. A linear guide rail 401 is arranged on the mounting panel 10 below the support plate 40, and the support plate 40 is mounted on a slider on the linear guide rail 401. The fourth cylinders (38, 39) are connected to the support plate 40 respectively. By extending and retracting the fourth cylinders (38, 39), the support plates 40 on opposite sides of the material discharge through hole on the mounting panel 10 are driven to move towards each other or away from each other. A baffle 41 is provided on the support plate 40. The baffle 41 is driven to move towards each other or away from each other by a fifth cylinder (not shown) provided on the support plate 40. It is used to clamp the ink cartridge tray pushed by the transverse moving assembly 4. The ink cartridge tray is supported by the support plate 40. The positioning baffles 37 and 41 located on the outer sides of the material discharge through hole above the material discharge compartment of the mounting panel 10 are used to position the ink cartridge tray placed on the support plate 40. Sensors are respectively installed on the mounting panels 10 on both sides of the support plate 40 along its length. Among them, a sensor 42 is installed near the transition component 3 to detect the presence or absence of the ink cartridge tray, and a sensor 43 is installed near the positioning baffle 37 to detect the ink cartridge tray being pushed into place. Sensors 42 and 43 are located on the same side of the mounting panel 10. Cylinder sensors (44 and 45) are respectively installed on the fourth cylinders (38 and 39).

[0040] The robotic arm delivery component 6 includes a SCARA robotic arm with a suction cup 46 at its end. The suction cup 46 is connected to an air source via an air tube. The suction cup 46 picks up ink cartridges placed in the ink cartridge tray on the support plate 40, and then the robotic arm transports the ink cartridges one by one to the next process.

[0041] The barcode reader assembly 7 is mounted on a support frame on one side of the robotic arm delivery assembly 6. The barcode reader assembly 7 includes a universal joint assembly and a barcode reader mounted on the universal joint assembly. The scanning surface of the barcode reader faces the displacement path of the robotic arm when picking up and placing ink cartridges, so as to facilitate scanning the S / N code on the ink cartridge and inputting the scanned S / N code into the system.

[0042] The AI ​​event camera detection component 8 is mounted on a support frame above the positioning baffle 37, facing the transport path of the robotic arm delivery component 6. The AI ​​event camera detection component 8 includes a universal joint assembly and an AI camera mounted on the universal joint assembly. When the robotic arm delivers the ink cartridge, the AI ​​camera monitors in real time to ensure that the employee is not within the work area. If the camera detects an employee within the work area, it stops the equipment operation.

[0043] The workflow of this invention:

[0044] 1) Turn on the power switch, connect the air source, manually place a stack of ink cartridge trays on the material tray 13, and then manually pull the positioning plate 16 to the right. After the positioning plate is in place, the sensor that senses the positioning plate responds, press the start button, the lead screw motor 14 moves, and the lead screw 11 drives the material tray 13 and the ink cartridge tray placed on it to rise in a straight line. The sensor 18 detects that the ink cartridge tray is in place, and the lead screw motor 14 stops moving.

[0045] 2) When the top ink cartridge tray reaches the loading position, sensor 18 responds, the first cylinder 23 moves, driving the pneumatic gripper 28 to move downwards to the position. The gripper 29 grips the end of the ink cartridge tray near the discharge hole. The first cylinder 23 moves again, driving the pneumatic gripper 28 to move upwards, lifting the end of the ink cartridge tray facing the discharge hole, so that it is separated from the end of the ink cartridge tray below it. The second cylinder 30 drives the partition plate 31 to extend into the bottom of the top ink cartridge tray. The pneumatic gripper 28 moves, releasing the gripper 29, allowing the ink cartridge tray to fall onto the partition plate 31.

[0046] 3) When the front sensor of the third cylinder detects that the ink cartridge tray has fallen onto the isolation plate 31, the third cylinder 32 is activated, driving the push plate 34 to push the ink cartridge tray from above the feeding through hole to the support plate 40 of the positioning telescopic component of the material picking and positioning component above the discharging through hole. The ink cartridge tray is positioned by the positioning baffle 37 and the baffle 41. After the ink cartridge tray is in place, the sensor 43 responds and triggers the third cylinder to drive the push plate to reset. When the sensors 17, 19, and 42 detect that there is no ink cartridge tray at the feeding position, they transmit a signal to the lead screw motor 14 to activate it to continue feeding.

[0047] 4) Sensor 43 responds, the air supply to the robotic arm delivery component is turned on, the AI ​​camera of the AI ​​event camera detection component 8 is activated, the robotic arm moves, moving the suction cup 46 above the ink cartridge to hold it. When the robotic arm places the ink cartridge into the target carton, the barcode reader component 7 reads the ink cartridge's S / N code and inputs it into the system. The robotic arm sequentially moves the ink cartridges from the ink cartridge tray. When there are no ink cartridges in the tray, it checks whether there is a vacuum by checking the suction cup 46. If there is no vacuum, it sends a signal to the fourth cylinder (38, 39). When cylinders (38, 39) move, the support plates 40 of the two sets of positioning telescopic components move away from each other, causing the empty ink cartridge tray to lose the support of the support plates 40 and fall freely into the buffer plate in the unloading hopper. Sensors 17, 19, 42 respond and trigger the feeding component to continue feeding. After the fourth cylinder (38, 39) moves to its position, the telescopic positioning sensor on the fourth cylinder (38, 39) responds, the fourth cylinder (38, 39) resets, and the positioning support component resets to the support position, waiting for the next ink cartridge tray.

[0048] When the unloading hopper on the right side of rack assembly 1 is full, the sensor in the unloading hopper will alarm, and the door panel needs to be opened manually to remove the empty ink cartridge tray. Repeat the above steps to complete the automatic packing of ink cartridges.
