[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

Example

[0020] To address the shortcomings of existing technologies that rely on manual inspection of displays, reference Figure 1 and Figure 2As shown, this application discloses an automated optical inspection device for laboratory displays, including a belt conveyor 10 arranged along a first direction. Multiple dual-station placement seats 20 are arranged on the belt of the belt conveyor 10 along the conveying direction. Inspection chambers 30 are respectively arranged on both sides of the middle section of the belt conveyor 10. Openings 31 are respectively opened on both sides of the two inspection chambers 30 in a second direction. Optical inspection units 40 are respectively arranged on the inner top walls of the two inspection chambers 30. A dual-drive moving unit 50 is connected between the two inspection chambers 30. Preferably, the dual-drive moving unit 50 is dual-drive... A type of servo screw module or bidirectional drive cylinder is used. The two drive parts of the dual drive moving unit 50 are respectively connected to the loading and unloading robot 60 for gripping the display. An easy-tear label feeder 70 (a known feeder feeder) is provided on the outside of one side of the rear section of the belt conveyor 10. A single drive moving unit 80 is mounted above the rear section of the belt conveyor 10 corresponding to the easy-tear label feeder 70. Preferably, the single drive moving unit 80 is a single drive servo screw module. A labeling robot 90 for labeling is connected to the drive part of the single drive moving unit 80. In practical implementation, the starting point of the belt conveyor 10 is set as the display unloading position. At this unloading position, two completed displays are placed on the dual-station placement seat 20. Under the conveyor belt 10, when two displays arrive at their corresponding inspection chambers 30, the dual-drive moving unit 50 drives two loading / unloading robots 60 to transport and place the two displays into the inspection chambers 30. After the operator powers on the displays, the two optical inspection units 40 in the two inspection chambers 30 perform optical inspections on the two displays. When the inspections of the two displays are completed, the dual-drive moving unit 50 drives the two loading / unloading robots 60 to transport the two displays back to the dual-station placement seat 20 of the belt conveyor 10. Driven by the system, the system continues to move backward. Furthermore, if either of the two displays fails the test, when they reach the corresponding easy-tear label feeder 70, the single-drive moving unit 80 drives the labeling robot 90 to remove an easy-tear label from the feeder 70 and attach it to the corresponding display. This allows operators to easily distinguish between qualified and unqualified products. Conversely, if both displays pass the test, the single-drive moving unit 80 does not drive the labeling robot 90 to remove the easy-tear label from the feeder 70 and attach it to the display. Additionally, the end of the belt conveyor 10 is designated as the display detection and unloading position. Here, operators can remove the completed displays and sort the products according to the labeling situation.

[0021] refer to Figure 3As shown, in order to facilitate precise placement of the monitor, this application provides two first contour positioning slots 21 for placing the monitor on the upper surface of the dual-station placement seat 20. At the beginning of the conveyor with the conveyor line, the operator needs to place the monitor that is coming off the line into the first contour positioning slot 21.

[0022] Additionally, refer to Figure 4 As shown, this application also provides a single-station placement seat 32 inside the testing chamber 30. The upper surface of the single-station placement seat 32 is provided with a second contour positioning groove 321 for placing the display. The side of the single-station placement seat 32 is provided with a clearance groove 322 connected to the second contour positioning groove 321. The testing chamber 30 is provided with a plug 33 for powering the display. In specific implementation, the loading and unloading robot 60 needs to move the display to be tested from the belt conveyor 10 to the second contour positioning groove 321. After that, the operator needs to pass the plug 33 through the clearance groove 322 and plug it into the display. At this time, the display is powered on, which facilitates the subsequent testing by the photoelectric detection unit.

[0023] Specifically, the optical detection unit 40 of this application includes an RGB camera 41 and a CCD lens 42 disposed at the bottom of the RGB camera 41. In specific implementation, the RGB camera 41 and the CCD lens 42 disposed at the bottom of the RGB camera 41 cooperate to detect the display panel of the entire display and determine whether there are any abnormalities on its surface. Note: The RGB camera 41 needs to be connected to an external computer system (which is not the subject matter claimed in this application and will not be described in detail here) for control and processing.

[0024] In one specific embodiment, the loading / unloading robot 60 of this application includes a pneumatic slide 61 connected to the drive unit of the dual-drive moving unit 50, a T-shaped robotic arm 62 connected to the pneumatic slide 61, and a plurality of first pneumatic suction heads 63 disposed on the bottom side of the transverse portion of the T-shaped robotic arm 62. During the process of gripping the display at the inspection chamber 30 or the belt conveyor line 10, the pneumatic slide 61 drives the T-shaped robotic arm 62 to descend into position, and then controls the first pneumatic suction heads 63 at its bottom to suck air, thereby gripping the display. Conversely, during the process of lowering the display at the inspection chamber 30 or the belt conveyor line 10, the pneumatic slide 61 drives the T-shaped robotic arm 62 to descend into position, and then controls the first pneumatic suction heads 63 at its bottom to expel air, thereby lowering the display.

[0025] In one specific embodiment, the labeling robot 90 of this application includes 91 connected to a single drive moving unit 80, a lead screw stepper motor 92 mounted on 91, and a second pneumatic suction head 93 connected to the bottom of the lead screw shaft of the lead screw stepper motor 92. When gripping an easy-to-remove label, the single drive moving unit 80 drives 91 to above the easy-to-remove label feeder 70. After reaching the desired position, the lead screw stepper motor 92 controls the second pneumatic suction head 93 to descend into position, and the second pneumatic suction head 93 is then controlled to suck air. A label is picked up from the easy-tear label feeder 70 (after the label is picked up, the lead screw stepper motor 92 drives the second pneumatic suction head 93 to reset). When the easy-tear label is being applied, the single drive moving unit 80 drives 91 to the top of the defective display. After it is in position, the lead screw stepper motor 92 controls the second pneumatic suction head 93 to descend into position. Controlling the second pneumatic suction head 93 to expel air will allow the easy-tear label to be applied to the display (after the label is applied, the lead screw stepper motor 92 drives the second pneumatic suction head 93 to reset).
