Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0014] Example

[0015] To address the aforementioned technical problems, this embodiment provides a touchscreen appearance inspection device, such as... Figure 1-2As shown, the device includes a mounting platform 10, a linear drive module 20 mounted on the mounting platform 10, a movable seat 30 mounted on the drive end of the linear drive module 20, a rotary table 40 rotatably mounted on the movable seat 30, a plurality of support fixtures 50 for fixing the touch screen mounted on the rotary table 40, a two-axis drive mechanism 70 mounted on the mounting platform 10 above the linear drive module 20, and a plurality of vision inspection modules 60 corresponding to the support fixtures 50 mounted on the two-axis drive mechanism 70. The robot then loads multiple assembled touchscreens onto the support fixture 50, which clamps and fixes the touchscreens. The linear drive module 20 then moves the support fixture 50 to below the vision inspection module 60. The two-axis drive mechanism 70 adjusts the height of the vision inspection module 60, which then simultaneously performs visual inspection on the upper surface of each touchscreen on the support fixture 50. This enables simultaneous automatic inspection of multiple touchscreens, improving inspection efficiency and accuracy to meet the ever-expanding production capacity.

[0016] Furthermore, a receiving groove 51 is provided on the bearing surface of the bearing fixture 50, and a clamping cylinder 52 is provided on the side of the bearing fixture 50. A clamping block 53 is provided at the driving end of the clamping cylinder 52. The touch screen is then placed in the receiving groove 5 for positioning, and the clamping cylinder 52 drives the clamping block 53 to abut against the side of the touch screen, thereby clamping and fixing the touch screen in conjunction with the receiving groove 51. Alternatively, in some other embodiments, the clamping cylinder 52 is a bidirectional cylinder, and clamping blocks 53 are provided at both ends of the bidirectional cylinder. The bidirectional cylinder drives the clamping blocks 53 to clamp the two sides of the touch screen, and the vision inspection module 60 performs visual inspection by taking pictures of the upper surface of the touch screen.

[0017] Furthermore, in actual production, it may be necessary to inspect the sides of the touchscreen. For this purpose, the rotary table 40 is rotatably mounted on the movable base 30 via bearings. A rotary driver 41 is provided on one side of the movable base 30, and the driving end of the rotary driver 41 is connected to the rotary table 40. For example, the rotary driver 41 is a motor, which drives the rotary table 40 to rotate, thereby achieving the flipping of the rotary table 40.

[0018] Furthermore, the two-axis drive mechanism 70 includes a gantry frame 71 mounted on the mounting platform 10. A first drive assembly 72 is mounted on the gantry frame 71, and a second drive assembly 73 is mounted on the drive end of the first drive assembly 72. The vision inspection module 60 is mounted on the drive end of the second drive assembly 73. The first drive assembly 72 adopts a linear drive structure with a motor lead screw to adjust the horizontal position of the vision inspection module 60. The second drive assembly 73 uses a cylinder to drive the vision inspection module 60 to move up and down, thereby adjusting the focal length of the vision inspection module 60.

[0019] Furthermore, the mounting platform 10 is equipped with guide rails, and the movable seat 30 is slidably mounted on the guide rails. The linear drive module 20 drives the movable seat 30 to move back and forth along the guide rails, thereby loading the touchscreen onto the support fixture 50. Then, the linear drive module 20 moves the movable seat 30 to below the vision inspection module 60. After inspection, the linear drive module 20 drives the movable seat 30 to reset, thus unloading the inspected touchscreen, thereby completing the automated inspection process and improving inspection efficiency.

[0020] The visual inspection module 60 includes a light module 62 and a CCD camera 61 located above the light module 62. The light module 62 adjusts the brightness of the light source, and then the CCD camera 61 performs visual inspection by taking pictures.

[0021] In summary, this application's solution involves setting a linear drive module on a mounting platform, a movable base at the drive end of the linear drive module, a rotatable rotary table on the movable base, and several carrier fixtures for fixing touchscreens on the rotary table. A two-axis drive mechanism is positioned above the linear drive module on the mounting platform, and several sets of vision inspection modules corresponding to the carrier fixtures are mounted on the two-axis drive mechanism. A robot then loads multiple assembled touchscreens onto the carrier fixtures, which clamp and fix the touchscreens. The linear drive module moves the carrier fixtures below the vision inspection modules, and the two-axis drive mechanism adjusts the height of the vision inspection modules. The vision inspection modules then simultaneously perform visual inspection on the upper surface of the touchscreens on each carrier fixture, enabling simultaneous automatic inspection of multiple touchscreens, improving inspection efficiency and accuracy, and meeting the needs of ever-expanding production capacity.

[0022] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
