[0028] Example

[0029] This embodiment provides a dual-channel electrode weighing and sorting machine, such as... Figures 1-4 As shown, it includes: a base plate 1, support legs 2 symmetrically arranged at the bottom of the base plate 1, a controller 3 fixedly installed at the bottom of the base plate 1, an electronic scale 4 fixedly installed at the center of the upper surface of the base plate 1, a weighing pan 5 on the top of the electronic scale 4, a collection rack 8 on the top of the base plate 1, and a weighing component 6 on the top of the base plate 1.

[0030] The weighing component 6 includes a positioning frame 605, which is fixedly connected to the center of the upper surface of the base plate 1. Two sets of first motors 601 are fixedly installed at the bottom of the positioning frame 605. A rotating frame 602 is fixedly connected to the output shaft end of the first motor 601. First electric push rods 603 are symmetrically arranged at the bottom of the rotating frame 602. An electric suction cup 604 is fixedly connected to the movable end of the first electric push rod 603.

[0031] A dual-channel electrode weighing and sorting machine employing the above technical solution mainly utilizes a first motor 601 to drive a rotating frame 602 to rotate. This causes a set of electric suction cups 604 to move directly above the loading rack 7. The first electric push rod 603 is activated, causing the electric suction cups 604 to move downwards and activate, adsorbing the electrode sheets onto their bottoms. At this point, the first motor 601 rotates again, and the electric suction cups 604 with the electrode sheets move above the weighing pan 5, placing the electrode sheets down for weighing. The other set of electric suction cups 604 continues to adsorb electrode sheets. Simultaneously, the other set of first motors 601 drives the electric suction cups 604 to move above the weighing pan 5, picking up the weighed electrode sheets and continuing to rotate. The electric suction cups 604 without electrode sheets move above the weighing pan 5 to pick up the weighed electrode sheets, and the cycle repeats. This improves production efficiency.

[0032] In order to accurately pick up the electrode sheets, a feeding rack 7 is fixedly connected to the upper surface of the base plate 1. The center distance between the feeding rack 7 and the weighing pan 5 is the same as the length of the rotating frame 602.

[0033] In order to transport the weighed electrode sheets to different collection racks 8, a screening assembly 9 is provided on the base plate 1. The screening assembly 9 includes a conveyor belt 901, which is located above the base plate 1. A second motor 902 is fixedly installed on one side of the conveyor belt 901, and support plates 903 are symmetrically arranged at the bottom of the conveyor belt 901.

[0034] To achieve automatic unloading, a fixing plate 904 is fixedly connected to the bottom of the positioning frame 605. Proximity sensors 905 are equidistantly arrayed at the bottom of the fixing plate 904. A fixing frame 906 is fixedly connected to one side of the conveyor belt 901. A second electric push rod 907 is fixedly installed on the fixing frame 906, and a push plate 908 is fixedly connected to the movable end of the second electric push rod 907. The weighed electrode data is sent to the controller 3. The controller 3 controls the movement of the conveyor belt 901, moving the electrode to the corresponding collection rack 8. The second electric push rod 907 is then activated, driving the push plate 908 to push the electrode into the collection rack 8 for collection.

[0035] To ensure the electrode sheets fall precisely into the collection rack 8 for collection, each rack is equipped with a corresponding proximity sensor 905. The signal output terminal of the proximity sensor 905 is electrically connected to the signal input terminal of the controller 3, and the signal output terminal of the controller 3 is electrically connected to the signal input terminal of the second motor 902. Upon sensing the signal from the proximity sensor 905 at the corresponding position, the second motor 902 stops rotating, causing the electrode sheet to move to the corresponding position on the collection rack 8.

[0036] To avoid damaging the electrode sheets, the pusher plate 908 is the same length as the conveyor belt 901, and a rubber pad is provided on one side of the pusher plate 908. The pusher plate 908 moves to push the electrode sheets into the collection rack 8.

[0037] To better control the operation of the equipment, controller 3 is configured as a programmable PLC controller. The signal output terminal of controller 3 is electrically connected to the signal input terminal of the first motor 601, and the signal output terminal of electronic scale 4 is electrically connected to the signal input terminal of controller 3. Electronic scale 4 sends the weighing result to controller 3, which controls the second motor 902 to rotate, causing the conveyor belt 901 to move the electrode plates to the corresponding positions.

[0038] In summary, the dual-channel electrode weighing and sorting machine provided in this embodiment has the following advantages: The first motor 601 drives the rotating frame 602 to rotate, thereby moving a set of electric suction cups 604 directly above the loading rack 7. The first electric push rod 603 is activated, causing the electric suction cups 604 to move downwards and activate, adsorbing the electrode onto their bottom. At this time, the first motor 601 rotates again, and the electric suction cups 604 with the electrode attached move above the weighing pan 5, placing the electrode down for weighing. The other set of electric suction cups 604 continues to adsorb electrode. Then, the other set of first motors 601 drives the electric suction cups 604 to move above the weighing pan 5, picking up the weighed electrode and continuing to rotate. The electric suction cups 604 without the electrode attached move above the weighing pan 5 to continue picking up the weighed electrode, and the cycle repeats. This improves production efficiency.

[0039] In use, the electrode to be weighed is placed on the loading rack 7. The first motor 601 drives the rotating frame 602 to rotate, thereby moving a set of electric suction cups 604 directly above the loading rack 7. The first electric push rod 603 is activated, causing the electric suction cups 604 to move down and start, adsorbing the electrode to the bottom of the electric suction cups 604. At this time, the first motor 601 rotates again, and the electric suction cups 604 with the electrode moves to above the weighing pan 5, where the electrode is placed down for weighing. The other set of electric suction cups 604 continues to adsorb the electrode. At this time, the other set of first motors 601 drives the electric suction cups 604 to move to above the weighing pan 5, picks up the weighed electrode, and continues to rotate. The electric suction cups 604 without the electrode moves to above the weighing pan 5 and continues to pick up the weighed electrode, and the cycle repeats. After being weighed, the electrode falls onto the surface of the conveyor belt 901. According to the signal sent by the controller 3, the electrode is transported to the corresponding collection rack 8. The second electric push rod 907 is activated to drive the push plate 908 to move, pushing the electrode on the conveyor belt 901 into the corresponding collection rack 8.

[0040] In outlining the operating principles and disclosing controller and sensor models, we can further refine the description and specify some common controller and sensor models suitable for such applications. Please note that the models listed below are for illustrative purposes only; the actual selection should be determined based on specific requirements and equipment specifications.

[0041] The working process of the dual-channel electrode weighing and sorting machine provided in this embodiment is as follows:

[0042] Feeding and weighing:

[0043] The electrode sheets are placed on the loading rack 7 on the base plate.

[0044] The controller 3 starts the first motor 601, which drives the rotating frame 602 to rotate directly above the loading frame 7.

[0045] The first electric push rod 603 extends, causing the electric suction cup 604 to descend and adsorb the electrode.

[0046] The rotating frame 602 rotates, moving the electric suction cup 604 with the electrode plate above the weighing pan 5. The electric suction cup 604 releases the electrode plate for weighing.

[0047] Meanwhile, another set of electric suction cups 604 repeats the above process to adsorb new electrode sheets.

[0048] Screening and Collection:

[0049] After being weighed, the electrode sheet is picked up by another set of electric suction cups 604, rotated above the conveyor belt 901 and released.

[0050] Based on the weighing result of the electronic scale 4, the controller 3 controls the second motor 902 to start, driving the conveyor belt 901 to transport the electrode sheet to the corresponding collection rack 8 position.

[0051] When the electrode reaches the sensing range of the sensor 905, the sensor sends a signal to the controller 3, and the controller 3 stops the second motor 902.

[0052] The second electric push rod 907 extends, pushing the push plate 908 to push the electrode sheet into the collection rack 8.

[0053] Among them, controller 3 adopts a programmable PLC controller, such as a Siemens S7-1200 or Mitsubishi FX3U series PLC. These PLC controllers have powerful logic control capabilities and rich input / output interfaces, making them suitable for controlling this type of automated equipment.

[0054] sensor:

[0055] Proximity sensor 905: Inductive or capacitive proximity sensors, such as the Omron E2E-X series or Schneider XS series, can be selected. These sensors can accurately detect the approach of objects and output corresponding electrical signals to the controller.

[0056] Electronic Scale 4: High-precision, high-stability models should be selected, such as the Mettler Toledo ICS series or Sartorius BSA series. These scales offer high-precision weighing and fast data transmission capabilities, meeting the accuracy requirements for electrode weighing.

[0057] Please note that the models listed above are for illustrative purposes only. Actual selection should be based on specific equipment requirements, budget, and supplier recommendations. Furthermore, detailed testing and debugging are necessary during the equipment design and manufacturing process to ensure optimal coordination between components.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
