For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Reference Figure 1 to Figure 2According to the first aspect of the present invention, a frame pre-positioning device includes a frame 100, a frame 200, a rotating device 300, a positioning mechanism and a code scanning device 500. The frame 200 is provided with a positioning portion 210. The rotating device 300 is arranged on the frame 100. The frame 200 can be connected to the rotating device 300. The rotating device 300 can drive the frame 200 to rotate to a pre-positioning matching position and a code scanning position. The positioning mechanism is arranged on the frame 100 and is located in the circumference of the rotating device 300. When the frame 200 rotates to the pre-positioning matching position, the positioning mechanism can cooperate with the positioning portion 210 to calibrate the relative position of the frame 200 and the rotating device 300. The code scanning device 500 is arranged on the frame 100 and is located above the frame 200. When the rotating device 300 drives the frame 200 to rotate to the code scanning position, the code scanning device 500 can scan the frame 200 to read information. The frame can be connected to the rotating device 300, and the rotating device 300 can rotate the frame to a pre-positioning cooperation position, and the positioning mechanism cooperates with the positioning part 210 to position the frame so that the relative position of the frame in the rotating device 300 can be accurately positioned for subsequent testing, and the rotating device 300 can also drive the frame to rotate to the code scanning position so that the code scanning device 500 can read the information of the frame. The above structure can realize the pre-positioning and information reading of the frame, and then cooperate with the conveying structure to unload the material to the test position for testing. During the test, another frame can be placed on the rotating device 300 to perform the above-mentioned positioning and information reading processes. Such a cycle can improve the positioning detection efficiency.

[0033] Specifically, the frame 200 can be placed on the rotating device 300 by a manipulator, and the rotating device 300 can be provided with a loading and unloading position, which can facilitate the manipulator to place the frame 200. The manipulator places the frame 200 on the loading and unloading position, and then the rotating device 300 can connect the frame 200 and rotate it to a pre-positioning matching position. At the pre-positioning matching position, the positioning mechanism can cooperate with the positioning portion 210 of the frame 200. The specific positioning structure is not limited. It can be understood that when the positioning mechanism cooperates, the rotating device 300 can be separated from the fixed connection with the frame 200, and the positioning mechanism can connect the frame 200 with the rotating device 300. The relative position between the devices 300 is calibrated and positioned. After the frame 200 is positioned, the rotating device 300 can re-fix the frame 200 and drive the frame 200 to rotate to the code scanning position. The code scanning device 500 can sense the barcode on the frame 200 and read the information. After the reading is completed, the frame 200 can be rotated back to the loading and unloading position. The robot can remove it and place it on the test equipment for testing. During the test, the other frame 200 can be positioned and scanned. Therefore, through the above structure, the pre-positioning step will not take up the test time, so continuous testing can be achieved, thereby improving the test efficiency.

[0034] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the rotating device 300 includes a rotating mechanism 310, a connecting mechanism 320 and a control component.

The control component can control the rotating mechanism 310 to rotate the frame 200 to the pre-positioning matching position, and the control component can control whether the connecting mechanism 320 is connected to the frame 200. Through the above structure, the pre-positioning function of the frame 200 can be automatically realized, and the positioning efficiency can be improved.

The connecting mechanism 320 needs to be disconnected from the frame 200 when the positioning mechanism is working and unloading, and the connection start and stop of the connecting mechanism 320 can be controlled by the control component. Through the above structure, the pre-positioning function of the frame 200 can be automatically realized, and the positioning efficiency can be improved.

[0036] It should be noted that the control component is not limited to the above-mentioned embodiment, and other embodiments may also be adopted. For example, the control component may also realize the control of the selection mechanism and the connection mechanism 320 through a visual recognition system.

[0039] Specifically, the vacuum suction member 321 can be arranged along the circumference of the turntable 312 to improve the stability of the connection. It can be understood that the vacuum suction member 321 provides negative pressure through a vacuum pump, and can be connected to the working end face of the vacuum suction member 321 through a pipeline. The working end face can be provided with a suction cup, and the frame 200 can be sucked by the suction cup. Compared with the rigid connection, the force of the vacuum suction member 321 is softer, which can achieve connection without easily damaging the frame 200.

[0041] Specifically, the barcode scanner 520 can scan the barcode to read information. It can be understood that the barcode scanner 520 can be connected to the control component. When the barcode scanner 520 completes sensing and scanning the barcode, the control component can control the rotating device 300 to perform the next operation. The bracket assembly 510 can be an adjustable bracket, and the specific adjustment structure is not specifically limited. The barcode scanner 520 can adjust the scanning area through the bracket assembly 510 to adapt to different frame 200 specifications and different barcode positions.

[0042] Reference Figure 3 In some embodiments of the present invention, the bracket assembly 510 includes a base 511, an adjustment shaft 512 and an adjustment seat 513.

[0045] Specifically, the frame 200 is roughly circular in shape, the positioning portion 210 can be arranged at intervals of 120°, and similarly, the linear drive mechanism 410 can be arranged at intervals of 120° around the rotating device 300. The linear drive mechanism 410 can correspond to the positioning portion 210, and the linear drive member 411 can be a cylinder. The positioning seat 412 is connected to the cylinder output rod, and the cylinder can drive the positioning seat 412 to move toward the rotation center of the rotating device 300. The three positioning seats 412 are pressed against the frame 200 at the same time, so that the frame 200 can be aligned with the rotation center of the rotating device 300, thereby calibrating the center position of the frame 200.

[0046] Reference Figure 4 and Figure 6 It is understandable that four positioning parts 210 can be provided, and the positioning parts 210 are arranged at intervals of 90°. Similarly, four linear drive mechanisms 410 can be provided and arranged at intervals of 90°.

By providing the first positioning column 4121 and the second positioning column 4122, two specifications of the frame 200 can be positioned, and the compatibility is high.

[0050] Specifically, the setting positions of the first positioning column 4121 and the second positioning column 4122 can match two different specifications of the frame 200. The second positioning column 4122 is set close to the selection device, and the corresponding frame 200 is smaller in size. The second positioning column 4122 can be set shorter to avoid the specifications of the first positioning column 4121. The first positioning column 4121 is farther away from the center of the rotating device 300, and the corresponding frame 200 size that can be set is larger.

[0051] It should be noted that the positioning seat 412 is not limited to the above embodiment, and other embodiments may be adopted. For example, a third positioning column may be provided to further adapt to different sizes.
