[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0029] The color analyzer automatically adjusts and switches devices, such as Figures 1 to 4 As shown, including,

[0030] Host computer 1;

[0031] Camera 2 is connected to host computer 1. Camera 2 is set to face product 7 to obtain visual information including the size and positioning of the product.

[0032] Robot 3 is connected to host computer 1. Robot 3 can move in a controllable manner based on the robot control signals transmitted by host computer 1, including moving to the initial position according to the preset points of the robot type and adjusting the position according to the center point information obtained by visual information.

[0033] Color analyzer 6 is installed on the moving end of robot 3. Color analyzer 6 is connected to host computer 1. Host computer 1 transmits color analyzer control signals based on the arrival signal returned by robot 3. Color analyzer 6 receives color analyzer control signals and performs detection.

[0034] Specifically, this utility model uses engineering software 17 in the host computer 1 to switch the endpoint position of robot 3 (different heights). The engineering software 17 is connected to camera 2 and communicates with it. By recognizing the length and position of the upper frame of TV product 7, it calculates and corrects the left and right differences with the preset point, and adjusts the color analyzer 6 probe to be centered in the horizontal direction (the product height will not change with the movement of the two horizontal axes).

[0035] Based on the model code provided by the engineering software 17, robot 3 searches for the corresponding script data, including motion trajectory and endpoint position; through Modbus communication and I / O signal interaction, it checks the correctness of the model information; robot 3 combines the data recognized and calculated by camera 2 to correct the preset path and endpoint position, and switches the adjustment and inspection process of color analyzer 6.

[0036] The engineering software 17 of this utility model is MACS2 software. The automatic adjustment and switching workflow of the color analyzer 6 of this utility model is as follows:

[0037] Step 1, open the MACS2 software;

[0038] Step 2: Connect and wait for camera 2 to start. The software will read the product size and positioning information captured by camera 2.

[0039] Step 3: The software establishes a connection with robot 3 via Modbus communication and sends the model code and the center point information processed by camera 2.

[0040] Step 4: Robot 3 compares the received model code with the current model information. If they are the same, it returns the current model information. If they are different, it selects the corresponding point in the model library of Robot 3 according to the model code, compares it with the center point information processed by camera 2, and returns the new model information.

[0041] Step 5: The MACS2 software receives the model information returned by Robot 3 and compares it again. If it is incorrect, an alarm is triggered and manual intervention is required. If it is correct, an I / O signal is sent for adjustment.

[0042] Step 6: Trigger robot 3's action via I / O signals. The action process includes:

[0043] Move to the initial position according to the preset points of the machine model;

[0044] The center point is adjusted based on the data processed by camera 2;

[0045] Distance is detected by ultrasonic sensor 4 to achieve speed reduction within a preset range;

[0046] After the color analyzer 6 probe contacts the screen of product 7, the robot 3 stops moving when the pressure sensor 5 reaches the threshold.

[0047] Step 7: Robot 3 returns an I / O signal. After MACS2 receives the signal, it calls color analyzer 6 to start adjustment. After the adjustment is completed, product 7 is automatically released.

[0048] Step 8: Repeat step 2 until all products 7 have been tested or the process is stopped by intervention.

[0049] This invention allows for quick, flexible, and accurate switching of inspection processes without human intervention.
