[0034] At the same time, it should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence; it should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0035] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not used to limit this application.

[0036] First, as Figure 1-2 As shown, the present invention discloses a method for automatically retrieving a program, comprising a host and at least one slave located in the same local area network, a shared folder is set in the host, and the dispensing program of each slave is stored in the shared folder. Each slave has the authority to read the shared folder, but does not have the authority to write to the shared folder. The dispensing program of each slave can be edited on the host;

[0037] The program automatic retrieval method comprises the following steps: setting the program path, program reference point and light source adjustment parameters on the host according to the current slave device information, wherein the dispensing program is located in the program path, and the program path is the storage location of the shared folder on the host;

[0038] The device reference point of the current slave device is established on the slave device. Since the dispensing position baffles of each slave device are inconsistent, the device reference point of the current slave device is set on each slave device.

[0039] The system reference point is calculated according to the program reference point and the device reference point; the dispensing program on the host can be directly called by using the system reference point on each slave;

[0040] Adjust the light source of the current slave device according to the light source adjustment parameters; because the light sources of each slave device are different over time, the circuits and components age, which may lead to inconsistent light source brightness under the same parameters. When performing a dispensing program, the light source parameters follow the current slave device, so calling the current dispensing program to other devices may lead to inconsistent light source brightness, which will cause the program reference point capture to fail.

[0041] Moving the camera according to the system reference point to perform a test grab;

[0042] Determine whether the grab is successful, if yes, run the next step, otherwise adjust the light source of the current slave device according to the light source adjustment parameters, and retest the grab;

[0043] The slave downloads the dispensing program that matches the current slave device from the host according to the program path and dispensing program name;

[0044] The slave and the host exchange data based on the system reference point. The slave uploads the system reference point parameters to the host, and the host saves them as the system reference point of the current slave device. The system reference point is the actual dispensing position of the workpiece on the current slave device.

[0045] In one embodiment, the motion range of the dispensing machine is a plane coordinate system, the program reference points include the first program reference point, marked as (X1, Y1) and the second program reference point (X2, Y2) in the coordinate system, the device reference point uses the dispensing baffle as the X coordinate and the track as the Y coordinate, marked as (X3, Y3), and the system reference points include the first system reference point (X4, Y4) and the second system reference point (X5, Y5).

[0046] In one embodiment, calculating the system reference point based on the program reference point and the device reference point includes: calculating the system first reference point based on the device reference point and the program first reference point, that is, (X4, Y4) = (X3-X1, Y3-Y1), calculating the system second reference point based on the device reference point and the program second reference point, that is, (X5, Y5) = (X3-X2, Y3-Y2), when the product placement angle changes, the angle of rotation of the product can be known based on the two reference points, and the angle is converted into coordinates through trigonometric functions.

[0047] In one embodiment, the light source adjustment parameters include: a lower limit deviation value, an upper limit deviation value and an adjustment interval value.

[0048] When testing the capture, if the capture fails for the first time, the light source will be automatically adjusted according to the range of the lower limit deviation value, upper limit deviation value and adjustment interval value, and the capture will be performed again. For example, the lower limit deviation value is 50, the upper limit deviation value is 250, and the adjustment interval value is 50. That is, the capture is performed at 50, 100, 150, 200, and 250 brightness. During this period, as long as the system reference point is captured, the next adjustment will not be performed. If the capture fails after five attempts, the system will prompt that the capture failed.

[0049] In one embodiment, the camera is moved according to the system reference point to perform test grabbing, including selecting a target area in the picture taken by the camera, selecting a reference point area in the target area, and identifying whether the system reference point in the reference point area meets the test standards. If it meets the test standards, normal dispensing can be performed. If it does not meet the test standards, the light source of the current slave device is adjusted according to the light source adjustment parameters, and the grabbing is retested.

[0050] Second, as Figure 3 As shown, the present invention discloses a program automatic retrieval system, which is applied to the above-mentioned program automatic retrieval method, including: a program path setting module, which is used to set the path, authority and calling method of the shared folder, and is suitable for the dispensing program interaction between the host and the slave;

[0051] The program reference point setting module is used to set the program reference point information of the current dispensing program, but will not modify the coordinates in the dispensing program;

[0052] The system reference point setting module is used to store the system reference point information of the current dispensing program corresponding to the current slave device;

[0053] A light source adjustment module, used to set light source adjustment parameters, and adapted for the slave to automatically adjust the light source of the current slave device according to the light source adjustment parameters;

[0054] The test capture module is suitable for the slave to perform test capture according to the system reference point.

[0055] In one embodiment, the calling method includes: scanning-free calling and normal calling. Scanning-free calling means directly running the dispensing program without performing test capture.

[0056] In one embodiment, the light source adjustment module includes: adjusting the light intensity of light sources of different colors separately, adjusting the light intensity of light sources of different colors simultaneously, and adjusting the light intensity of a combination of light sources of different colors.

[0057] It can be understood that the light intensity of different colors of light sources such as R, G, and B light sources can be selected between 0-255, and adjusted according to the darkness of the picture captured by the center of the camera. 0 is the darkest and 255 is the brightest. The light intensity of each color light source can be adjusted individually, and the light sources of RG, RB and GB can be adjusted in pairs, or the intensity of the combination of R, G, B three light sources can be adjusted at the same time.

[0058] In one embodiment, the test capture module includes: a picture display area for displaying pictures acquired by the camera and for selecting a target area and a reference point area;

[0059] The camera position area is used to display the current coordinates of the camera;

[0060] The camera control area allows you to manually adjust the camera position at different speeds and directions based on the camera's current coordinates.

[0061] In one embodiment, an offline import trajectory module is also included, which is used to offset the program reference point and compensate the offset value into the dispensing program.

[0062] In one embodiment, a notification module is further included, which is used to notify a slave machine that calls the dispensing program to update the dispensing program after detecting that the dispensing program has changed.

[0063] In one embodiment, a judgment module is also included to judge whether the test capture is successful.

[0064] It should be noted that the above-mentioned technical features are further combined with each other to form various embodiments not listed above, which are all deemed to be within the scope of the present invention; and, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should fall within the scope of protection of the claims attached to the present invention.
