[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. It should be noted that, under the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0022] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.
[0023] The figure numbers in this application are only used to distinguish the various steps in the scheme, and are not used to limit the execution order of the various steps. The specific execution order is subject to the description in the specification.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0025] Example 1 A method for visually fitting a smart watch screen, such as Figure 1 As shown, the following steps are included: S1, controlling the acquisition of the edge image of the smart watch case; like Figure 6 As shown, four image acquisition devices 1 are used to acquire the edge image of the smart watch case and the edge image of the screen module, namely the first camera 11, the second camera 12, the third camera 13, and the fourth camera 14. Each image acquisition device has a corresponding light source module 2 to provide light. In order to realize the independent acquisition of the edge image of the smart watch case and the edge image of the screen module, each image acquisition device 1 is configured with a corresponding first light source module 21 and a second light source module 22. Taking the first camera 11 as an example, Figure 7 As shown, the first light source module 21 provides light for the first camera 11 to capture the side edge image of the smart watch housing, and the second light source module 22 provides light for the first camera 11 to capture the side edge image of the screen module. Figure 7 The angle value between the second light source module 22 and the first camera 11 is only for illustration and does not limit the specific angle value.
[0026] In combination with the above embodiments, Figure 2 As shown, the S1 step includes: S11, controlling the first light source module to turn on and the second light source module to turn off; S12: Capture the edge image of the smart watch case by controlling the image acquisition devices corresponding to each side of the smart watch case.
[0027] Specifically, when all the first light source modules 21 are controlled to be turned on and all the second light source modules 22 are kept turned off, images of the four sides of the smart watch housing 5 are collected through the first camera 11, the second camera 12, the third camera 13, and the fourth camera 14 respectively.
[0028] S2, controlling the acquisition of edge images of the screen module; In combination with the above embodiments, Figure 3 As shown, the S2 step includes: S21, controlling the second light source module to turn on and the first light source module to turn off; S22, capturing the edge image of the screen module by controlling the image capturing device.
[0029] Specifically, when all the second light source modules 22 are controlled to be turned on and all the first light source modules 21 are kept turned off, the images of the four sides of the screen module 4 are collected by the first camera 11, the second camera 12, the third camera 13, and the fourth camera 14 respectively.
[0030] S3, converting the smart watch case edge image, the smart watch case edge coordinates, and the screen module edge coordinates in the screen module edge image into a motion mechanism coordinate system; Because the edge image of the smart watch case and the edge image of the screen module are taken using the same set of cameras, the edge image of the smart watch case and the edge image of the screen module need to call the same set of calibration relationships of the camera for conversion. Specifically, the step S3 includes: The calibration relationship of each image acquisition device is called to convert the edge coordinates of the smart watch housing and the edge coordinates of the screen module into the motion mechanism coordinate system.
[0031] In order to associate the camera coordinate systems of the four image acquisition devices 1 with the motion mechanism 3 for transporting the screen module 4, each pixel of each camera can be converted to the coordinate system of the motion mechanism 3, thereby achieving controllable screen assembly process. Figure 4 As shown, it also includes the step of determining the calibration relationship of the image acquisition device: S31, controlling the motion mechanism to absorb the calibration sheet; for example, using a checkerboard calibration sheet with a cell size of 0.5*0.5 mm, and adsorbing it onto the motion mechanism.
[0032] S32, controlling the first light source module to be turned on and the second light source module to be turned off; S33, controlling the motion mechanism to move to a preset position, and controlling all the image acquisition devices to simultaneously capture the image of the calibration plate; S34, controlling the motion mechanism to drive the calibration plate to translate for multiple times, and controlling all the image acquisition devices to simultaneously capture the calibration plate image after each translation; S35, controlling the motion mechanism to drive the calibration plate back to the preset position, and then performing multiple rotations, and controlling all the image acquisition devices to simultaneously capture the calibration plate image after each rotation; For example, the motion mechanism is controlled to carry the calibration piece and translate 9 times, then return to the preset position, and then perform the rotation action 3 times. In the 9+3 postures, the four image acquisition devices 1 all take pictures of the calibration piece. After the pictures are taken, each camera obtains 12 images.
[0033] S36. According to the changes in features in the calibration plate images taken by each of the image acquisition devices, the least square method is used to calculate the respective calibration relationships.
[0034] S4, determining the angle deviation between the edge of the smart watch case and the edge of the screen module according to the converted edge coordinates of the smart watch case and the edge coordinates of the screen module, and adjusting them to be parallel; Specifically, Figure 5 , Figure 8 As shown, the S4 step includes: S41, calculating the angles of the two long sides of the inner wall of the smart watch case according to the converted edge coordinates of the smart watch case, and the long side 51 of the inner wall of the smart watch case 5 is as follows: Figure 8 As shown; S42, calculating the angles of the outer edges 41 of the two long sides of the screen module 4 by using the converted edge coordinates of the screen module; S43, calculating the difference between the average value of the angles of the two long sides of the inner wall of the smart watch housing and the average value of the angles of the two long sides of the screen module to obtain the angle deviation, such as Figure 8 shown.
[0035] S5, executing steps S1 to S3 again to calculate the translation amount of the smart watch housing and the screen module, and centering the smart watch housing and the screen module; S6. Loop through steps S1 to S5 until the angle deviation and the translation amount reach respective thresholds; for example, when the angle deviation is less than 0.1° and the translation amount difference is less than 0.04, it is considered that the loop termination condition is met.
[0036] S7. Control the motion mechanism to press downward to fit the smart watch housing and the screen module.
[0037] Through multiple rounds of precise visual guidance, this embodiment can control the alignment error of the screen components within an extremely small range, ensuring that the subsequent processes achieve clarity of the screen display and sensitivity of the touch control. Whether it is a flat screen or a curved screen, highly precise alignment can be achieved, and the occurrence of screen bonding failure or even scrapping can be significantly reduced.
[0038] This embodiment can monitor the bonding process in real time through visual guidance, promptly discover and correct position deviations caused by equipment vibration, material deformation and other factors, ensure the stability and consistency of bonding, help reduce product defective rates and improve production efficiency.
[0039] This embodiment can reduce scrap and rework caused by poor bonding through high-precision visual guidance, reduce the waste of raw materials and production costs; at the same time, improving production efficiency can also reduce the production cost per unit product and improve the competitiveness of the enterprise.
[0040] This embodiment provides a highly versatile visual guidance technology that can reduce an enterprise's investment in different equipment and reduce equipment procurement and maintenance costs; in addition, the automated visual guidance system can also reduce manual operations and reduce labor costs.
