[0055] Please see the appendix Figure 1This embodiment relates to an automated sorting line for sorting electronic paper display screens 100, specifically including a loading bin 1, a first vision mechanism 2, a loading mechanism 3, a barcode scanning mechanism 4, a detection platform 5, a unloading mechanism 6, and multiple unloading bins 7. The loading bin 1 contains multiple electronic paper display screens 100 stacked vertically, and the loading bin 1 can raise the electronic paper display screens 100 to the loading position. The first vision mechanism 2 is used to identify the electronic paper display screens 100 at the loading position. The loading mechanism 3 is signal-connected to the first vision mechanism 2 and is used to move the electronic paper display screens 100 to the barcode scanning position. The barcode scanning mechanism 4 is used to scan the electronic paper display screens 100 in the scanning position. The detection platform 5 is used to perform image recognition, pressing and lighting, and optical value detection on the electronic paper display screens 100 based on the barcode information.

[0056] Specifically, firstly, a stack of packaged electronic paper display screens 100 is placed on the loading hopper 1 manually or using a conveyor. The electronic paper display screens 100 are typically received in batches, with multiple screens stacked together. The loading hopper 1 not only holds the electronic paper display screens 100 but also lifts the topmost screen to the loading position. When the screen reaches the loading position, the first vision mechanism 2 performs position recognition and shape positioning on the screen at the loading position and transmits the positioning information to the loading mechanism 3.

[0057] In this embodiment, the entire sorting process includes automatic feeding, automatic identification, automatic positioning, automatic detection, and automatic unloading, which fully realizes the automated sorting of electronic paper display screens 100, improves sorting efficiency, reduces material waste, and lowers labor costs.

[0058] Please see the appendix Figure 2 Optionally, the feeding hopper 1 includes a support frame 11 and a lifting drive component 12. The lifting drive component 12 is used to drive the support frame 11 to rise and fall, and the electronic paper display screen 100 is stacked on the support frame 11.

[0059] In this embodiment, the feeding bin 1 includes a support frame 11, which is a frame-type mechanism composed of multiple rods and plates. The electronic paper display screens 100 are stacked on the support frame 11. The lifting drive component 12 can be a linear motor or a linear cylinder, which is used to drive the electronic paper display screens 100 to move in the vertical direction and to transport the electronic paper display screens 100 to the feeding position. This feeding bin 1 has a simple mechanism, is easy to operate, and has a relatively small overall volume.

[0060] Of course, a transmission mechanism can also be connected between the lifting drive component 12 and the support frame 11. For example, an intermediate transmission form such as a chain or worm gear can be used. Those skilled in the art can select the intermediate transmission form according to the overall structure and layout of the entire feeding bin 1.

[0061] Please see the appendix Figure 3 Optionally, the first vision mechanism 2 includes a fixed frame 21, a first camera 22 disposed on the fixed frame 21, and a first light source 23, wherein the first light source 23 is a surface light source.

The first camera 22 integrates a CCD (Charge-coupled Device) to improve resolution and sensitivity. The first camera 22 is used to take pictures and identify the electronic paper display screen 100 at the loading position. A first light source 23 is also provided below the first camera 22. The first light source 23 is a surface light source to ensure that all areas of the electronic paper display screen 100 are illuminated, thereby ensuring the consistency and accuracy of the picture and identification results of the electronic paper display screen 100.

[0063] Please see the appendix Figure 4 Optionally, the feeding mechanism 3 includes a first robotic arm 31, which can pick up the electronic paper display screen 100 and move the electronic paper display screen 100 along the horizontal plane.

[0064] In this embodiment, the first robotic arm 31 can move its position under the combined action of multiple first driving components to ensure an effective range and direction of movement. For example, two sets of linear motors or linear cylinders can drive the first robotic arm 31 to move in two dimensions of the horizontal plane. The working end of the first robotic arm 31 is provided with a vacuum suction cup for adsorbing the electronic paper display screen 100, thereby driving the electronic paper display screen 100 to move.

[0065] Please see the appendix Figure 5 -Appendix Figure 7Furthermore, the automated sorting line also includes a loading transfer platform 32, where the first robotic arm 31 can place the electronic paper display screen 100 on the loading transfer platform 32. The scanning mechanism 4 includes a scanning light source 41 and a barcode scanner 42, which scans the electronic paper display screen 100 located in the loading transfer platform 32.

[0066] In this embodiment, before inspecting the electronic paper display screen 100, it is necessary to identify the information of each electronic paper display screen 100. The first robotic arm 31 picks up the electronic paper display screen 100 and places it on the loading transfer platform 32. The barcode scanner 42 scans and identifies the one-dimensional or two-dimensional encoded information of the electronic paper display screen 100. At the same time, the relevant scanned information is transmitted to the processing system. In order to improve the scanning efficiency, the scanning light source 41 can be used to illuminate the area to be scanned.

[0067] In this embodiment, the loading transfer platform 32 can move the electronic paper display screen 100 under the action of the second driving component. The position of the barcode scanner 42 can also be manually adjusted, specifically by using a slide table and a sliding rod. After the slide table moves to the preset position, it is directly locked on the sliding rod to fix the barcode scanner 42.

[0068] To accommodate the layout of multiple mechanisms on the entire sorting line and to avoid excessive movement range of the first robotic arm 31, resulting in a cumbersome structure, this embodiment also includes a linear motor robotic arm 91.

The second camera 512 also integrates a CCD (Charge-coupled Device), and the third drive unit 513 can be a drive motor or a drive cylinder. The second camera 512 can photograph and identify the electrodes of the electronic paper display screen 100, thereby obtaining the accurate position of the electrodes of the electronic paper display screen 100, which prepares for the crimping and lighting of the electronic paper display screen 100. When the electrodes of the electronic paper display screen 100 are in the accurate position, they can be directly crimped and powered on through the crimping module 52. If the electrodes of the electronic paper display screen 100 are not in the accurate position, the detection platform 5 is also equipped with a correction mechanism to straighten the electronic paper display screen 100. The correction mechanism can also be in the form of a conventional robotic arm, which straightens the electronic paper display screen 100 by picking up or gripping it.

[0071] Please see the appendix Figure 8 and attached Figure 10 Optionally, the detection platform 5 also includes a crimping module 52, which is connected to the vision module 51 by signal. The crimping module 52 is used to align and crimp the electronic paper display screen 100 and power it on.

[0072] In this embodiment, the crimping module 52 includes multiple upper needle film crimping components 521 and multiple lower needle film crimping components 522 corresponding to the upper needle film crimping components 521. The upper needle film crimping components 521 and lower needle film crimping components 522 are crimped together according to the precise positions of the electrodes of the electronic paper display screen 100, thereby crimping the crimping electrodes of the electronic paper display screen 100. After power is applied, the electronic paper display screen 100 can be lit up, thus preparing for subsequent testing. The upper needle film crimping components 521 and lower needle film crimping components 522 are similar in structure to existing conventional crimping devices, and their structure and location will not be described in detail in this embodiment.

[0075] Please see the appendix Figure 13 and attached Figure 14 Optionally, the unloading mechanism 6 includes a second robotic arm 61, which is used to pick up and move the electronic paper display screen 100 in three-dimensional space.

[0076] In this embodiment, the second robotic arm 61 has a structure that is basically the same as that of the first robotic arm 31. It uses a feeding suction cup to adsorb the electronic paper display screen 100. At the same time, the second robotic arm 61 can move along three orthogonal directions in a spatial rectangular coordinate system. The second robotic arm 61 is driven by multiple sets of motors or cylinders.

[0077] Optionally, the automated sorting line also includes a second vision mechanism 8, which scans the electronic paper display screen 100 and then moves it to the corresponding unloading bin 7 via a second robotic arm 61.
