[0035] EMBODIMENT

[0036] In order to solve the series of problems existing in the prior art by naked eye detection of the back of the display module, with reference to the figures shown in Figure 1 and Figure 2 The present application discloses a display module back appearance detection device for detecting the back features of the display module (the features at least include the missing tape, no screw hole, connection port skew, label abnormality and the like in the background technology), which comprises a machine table 10, and a machine frame 20 arranged above the machine table 10.

[0037] An incoming material detection pipeline 30 is arranged above the machine table 10, which is used for placing the display module to be detected;

[0038] A positioning and clamping mechanism 40 is arranged above the incoming material detection pipeline 30, which is used for positioning and clamping the display module on the incoming material pipeline;

[0039] The qualified product unloading line 50 is arranged on the corresponding machine table 10 on the side of the feeding detection line 30 in the conveying direction, and is used for conveying and unloading the display module qualified in the detection;

[0040] The detection mechanism 80 is arranged on the bottom of the rack 20 opposite to the conveying end of the feeding detection line 30, and is used for detecting the back features of the display module;

[0041] The unqualified product unloading line 60 is arranged on the corresponding machine table 10 on the side of the qualified product unloading line 50 in the non-conveying direction, and is used for conveying and unloading the display module unqualified in the detection, and in one arrangement mode, the conveying end of the unqualified product unloading line 60 extends outward from the machine table 10;

[0042] The unqualified product carrying mechanism 70 is arranged on the corresponding machine table 10 on the outside of the conveying start end of the unqualified product unloading line 60, and is used for carrying the display module unqualified in the detection from the qualified product unloading line 50 to the unqualified product unloading line 60.

[0043] Based on the above structure, in the specific implementation, the operator places the display module to be detected on the feeding line on the outside of the machine table 10, and clamps it through the positioning and clamping mechanism 40, then the detection mechanism 80 detects the back of the display module once, according to the detection result, if the display module is qualified, the display module is directly unloaded through the qualified product unloading line 50, otherwise, if the display module is unqualified, the unqualified product carrying mechanism 70 carries the unqualified product on the qualified product unloading line 50 to the unqualified product unloading line 60, and the unqualified product is unloaded by the unqualified product unloading line 60.

[0044] In order to meet the detection needs of the display module, the feeding detection line 30, the qualified product unloading line 50 and the unqualified product unloading line 60 of the present application are composed of two belt lines driven by the same shaft, which is a part of the prior art and is easily understood in the technical field, and will not be described in detail here.

[0045] Reference Figure 4As shown, the positioning and clamping mechanism 40 of the present application comprises a rack 41, a bidirectional screw drive module and two clamping assemblies 43. The rack 41 is arranged above the material feeding detection flow line 30, the bidirectional screw drive module is arranged above the rack 41, and the two clamping assemblies 43 are respectively connected to the two driving parts of the bidirectional screw drive module 42. Each clamping assembly 43 comprises a sliding plate 431 connected to the driving part of the bidirectional screw drive module 42 and extending outwardly, and a plurality of clamping columns 432 arranged at the bottom of the sliding plate 431. When the display module conveyed on the material feeding detection flow line 30 reaches the designated position, the bidirectional screw drive module 42 drives the two sliding plates 431 to slide towards each other until the plurality of clamping columns 432 on the two sliding plates 431 clamp the display module from both sides. In addition, in order to prevent the clamping columns 432 from damaging the display module, the bottom of the clamping column is provided with a rubber roller 433, so that flexible clamping can be achieved. After the detection of the display module is completed, the bidirectional screw drive module 42 drives the sliding plate 431 to reset, and at this time, the material feeding detection flow line 30 can convey the detected display module to the qualified product unloading flow line 50.

[0046] Reference Figure 1 And Figure 2 As shown, the detection mechanism 80 of the present application comprises a vertical support 81 and a line array detection camera 84. The vertical support 81 is arranged above the bottom of the rack 20 opposite to the conveying end of the material feeding detection flow line 30. A vertical guide rail 82 is arranged on one side of the vertical support 81, and a sliding seat 83 fixed by bolts is slidably arranged on the vertical guide rail 82. The line array detection camera 84 is arranged on the sliding seat 83, and a lens 85 is arranged below the line array detection camera 84. When the display module is clamped above the material feeding detection flow line 30, the line array detection camera 84 cooperates with the lens 85 to detect the back of the display module. According to the picture obtained by the line array detection camera 84, the external processing system can automatically compare and detect the back of the display module. In addition, according to the detection needs, the sliding seat 83 can be slid to be fixed with the vertical guide rail 82, so that the height of the line array detection camera 84 can be adjusted to obtain a better shooting position.

[0047] In order to improve the detection accuracy of the line array detection camera 84, an LED lamp tube 90 facing the back of the product is arranged above the material feeding detection flow line 30 near the conveying end. In specific implementation, the light emitted by the LED lamp tube 90 illuminates the back of the display module.

The first blocking block 102 is connected to the piston rod of the first cylinder 101, and two first blocking rods 103 are arranged on the upper sides of the first blocking block 102 and can extend from between the material feeding detection assembly 30 and the qualified product discharging assembly. When the first cylinder 101 extends, the two first blocking rods will block the display module on the material feeding detection assembly 30. In this way, the display module can be kept on the material feeding detection assembly 30 to facilitate the positioning, clamping and back detection of the display module in the later stage. After the back detection of the display module is completed, the first cylinder 101 drives the first blocking block 102 to descend, so that the two first blocking rods are reset. In this way, the display module after detection can be conveyed to the qualified product discharging assembly 50.

The second blocking mechanism 110 includes a second cylinder 111 and a second blocking block 112. The second blocking block 112 is connected to the piston rod of the second cylinder 111, and two second blocking rods 113 are arranged on the upper sides of the second blocking block 112. When the display module is a qualified product, the display module conveyed by the material feeding detection assembly 30 will be directly discharged, and the second cylinder 111 will not drive the second blocking block 112 to rise. Conversely, if the display module is an unqualified product, the second cylinder 111 will drive the second blocking block 112 to rise to block the display module conveyed by the material feeding detection assembly 30, so as to facilitate the unqualified product carrying mechanism 70 to carry the unqualified product to the unqualified product discharging assembly 60 for discharging.

[0050] Referring to Figure 6As shown, the unqualified product carrying mechanism 70 of the present application comprises a four-axis robot 71 and a carrying clamp 72, the four-axis robot 71 is arranged on the corresponding machine table 10 outside the conveying start end of the unqualified product discharge assembly line 60, the carrying clamp 72 is connected to the execution end of the four-axis robot 71, the carrying clamp 72 comprises a carrying plate and two pneumatic slides 722, the two pneumatic slides 722 are arranged on opposite sides of the carrying plate respectively, two telescopic plates 723 are arranged on the two pneumatic slides 722 respectively, two L-shaped clamping plates 724 are arranged on the two telescopic plates 723 respectively, when the display module is detected as an unqualified product, the four-axis robot 71 drives the carrying clamp 72 to above the qualified product discharge assembly line, after reaching the position, the two pneumatic slides 722 drive the two telescopic plates 723 to move towards each other, in this process, the four L-shaped clamping plates 724 on the two telescopic plates 723 clamp the display module from both sides, when the four-axis robot 71 moves the carrying clamp 72 to the unqualified product discharge assembly line 60, the two pneumatic slides 722 will drive the two telescopic plates 723 to reset, at this time, the unqualified product discharge assembly line 60 can send the unqualified product out of the machine table 10.
