[0044] In the field of home appliance production, especially for home appliances with large size and weight, such as refrigerators, washing machines, air conditioners, etc., the handling process in their production process has always been a bottleneck restricting production efficiency. These home appliances are large in size and heavy in weight, and the gap between products is small during the stacking process. Ordinary handling tools are not suitable, so they mainly rely on manual handling. However, manual handling of large home appliances is not only labor-intensive, but also inefficient. This inefficient handling method will significantly affect the overall production progress. In addition, manual handling not only leads to high costs, but also easily causes safety accidents such as work-related accidents and product damage due to operator fatigue, inattention or improper operation.

[0115] like Figure 1-Figure 6 As shown, this embodiment provides an article handling system, which includes a lifting drive device (not shown) and the grasping mechanism as described above, wherein the grasping mechanism is provided with an identification device 7 and a display screen 6, wherein the identification device 7 is used to identify the size of the article to be handled, and the display screen 6 is electrically connected to the identification device 7;

[0116] The lifting drive device of the present application can adopt an existing mechanical arm, and control the movement of the mechanical arm by controlling the control button 13 to realize the lifting and lowering of the grasping mechanism.

[0117] The gripping mechanism is also provided with a counting device 8, and the counting device 8 is used to count the number of articles carried by the gripping mechanism.

[0118] The grabbing mechanism comprises a support frame 1, one side of the support frame 1 is connected to a lifting drive device, and a handle 12 is provided on the support frame 1;

[0119] The support frame 1 is also provided with a clamping assembly and a driving system 2. The clamping assembly includes two grabbing hands 3 arranged opposite to each other. Both grabbing hands 3 are slidably connected to the support frame 1. The driving system 2 is used to drive the grabbing hands 3 to move so as to change the relative distance between the two grabbing hands 3.

[0120] Specifically, the identification device 7, the display screen 6 and the counting device 8 are all fixed on the support frame 1. During use, the counting device 8 is electrically connected to the display screen 6. More preferably, the display screen 6 is installed in the control device, and the operation of the entire article handling system is controlled by the control device.

[0121] The identification device 7 identifies the size of the object to be transported and displays the identification data on the display screen 6 . The operator can control the movement of the grabber 3 according to the display data on the display screen 6 .

[0122] In a more preferred embodiment, a sensor for detecting the distance between the two grabbing hands 3 is also provided on the support frame 1 , and the sensor is connected to the display screen 6 so as to intuitively reflect the distance between the grabbing hands 3 .

[0123] The counting device 8 can adopt an infrared counting device to automatically count the number of items carried by the gripping mechanism. Automatic counting of the number of items can count the number in real time during the process of carrying the items, reducing manual intervention, thereby significantly improving the speed of carrying and counting. Secondly, automatic counting can ensure the accuracy of the data. Manual counting may lead to errors due to fatigue, distraction and other reasons, while the automatic counting system can ensure the accuracy of the statistical results through precise sensors and algorithms, thereby avoiding problems caused by data errors. In addition, automatic counting also helps to monitor and manage the number of items in real time. Through the automatic counting system, the changes in the number of items can be obtained in real time, which is of great significance for warehouse management, logistics scheduling and other aspects.

[0124] Example 9

[0125] This embodiment provides an article transporting method, which is implemented based on the article transporting system as described above.

[0126] See also Figure 7 , the method comprises the following steps:

[0127] S100, obtaining the size of the object to be transported, and displaying the obtained data on the display screen 6;

[0128] S200, controlling the movement of the grabbing hand 3 to grab the object to be transported according to the size of the object to be transported;

[0129] S300: After the items are transported, a counting is performed through the counting device 8.

[0130] This method automatically counts items after they are moved, which can ensure the accuracy of the data.

[0131] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
