Before the module detects, at first need place the module accurately behind the detection tool, just can treat the module that detects and detect. For example, before the testing process of the liquid crystal module, it is necessary to ensure that the liquid crystal module is accurately placed in the testing fixture, so that the liquid crystal module can be conducted with the testing fixture to illuminate the screen, thereby facilitating the testing of a series of performances such as appearance integrity, picture, brightness, color, and the like.

Because the types or sizes of the modules are different, different inspection jigs are often required to accommodate different modules during the inspection of the modules. When different detection jigs are used for switching stations, the detection jigs may change relative to the position of the workbench, for example, the detection jig is the first position at the last position and the second position at the next position, and in an ideal state, the second position should coincide with the first position, and because the detection jig has an error in the transferring process, the second position does not coincide with the first position. If the liquid crystal module is placed at the second position, the liquid crystal module has the risk of being incapable of being lightened. The existing liquid crystal module is placed in a detection jig, the mode of manual dotting and contraposition is adopted, and the mode has the problem of low efficiency. In order to solve the problem, researchers think that the module to be detected can be parallel to the current detection jig by acquiring the position difference value of the detection jig on the workbench and then adjusting the pose of the module to be detected through the adjusting mechanism, and then parallelly transferring the module to be detected after the pose is adjusted into the detection jig. It should be noted that the to-be-detected module is parallel to the detection jig, which means that the to-be-detected module can be placed on the detection jig in a parallel moving manner or a detection cavity corresponding to the detection jig.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a module detection device according to an embodiment of the present invention, and fig. 2 is a schematic block diagram of the module detection device of fig. 1. An embodiment of the present invention provides a module detection apparatus, including: the image recognition system comprises a workbench 100, an image recognition module 200, an adjustment module 310, a first transfer module 410 and a control module 500. The image recognition module 200 is used to recognize the position of the detection fixture 110 on the workbench 100, and it should be noted that the image recognition module 200 can recognize the detection fixtures 110 of different models, for example, according to the area size or surface identification of different detection fixtures 110. When the different inspection jigs 110 are initially mounted on the table 100, the respective positions are determined with respect to the table 100. Since the detection jig 110 has an error when the station is switched, and the position of the detection jig 110 relative to the workbench changes, the image recognition module 200 can determine whether the position of the detection jig 110 relative to the workbench 100 changes according to the comparison between the position information of the current detection jig 110 on the workbench 100 and the position information of the previous detection jig 110 on the workbench 100. In addition, the image recognition module 200 may also transmit the position information or the picture information of the two groups of detection jigs 110 to the control module 500, and the control module 500 calculates the difference value and then controls the adjustment module 310 to work, so that the adjustment module 310 adjusts the pose of the module to be detected; the first transfer module 410 can place the module to be detected adjusted by the adjusting module 310 in parallel in the detection fixture 110.

Specifically, the workbench 100 is provided with multiple types of detection jigs 110 for accommodating different types of modules to be detected respectively, and the multiple types of detection jigs 110 can switch stations on the workbench 100; the image recognition module 200 is arranged on the workbench 100 and used for recognizing and recording the positions of the detection tools 110 of various types relative to the workbench 100; the adjusting module 310 is arranged on the workbench 100, and the adjusting module 310 is used for accommodating the module to be detected and adjusting the pose of the module to be detected; the first transfer module 410 is arranged on the workbench 100, and the first transfer module 410 places the module to be detected adjusted by the adjusting module 310 in the detection jig 110 in parallel; the first transfer module 410 comprises a sucker assembly and sucks the module to be detected through the sucker assembly; the control module 500 controls the operations of the image recognition module 200, the adjustment module 310, and the first transfer module 410. The number of the image recognition modules 200 may be the same as the number of the detection tools 110. The control module 500 includes a PC and a PLC, and the control module 500 may analyze the position difference of the detection jig 110 photographed by the image recognition module 200 through the PC and control the adjustment module 310 and the first transfer module 410 to work through the PLC.

In this embodiment, the image recognition module 200 can recognize and record the positions of the detection jigs 110 corresponding to the workstations 100, respectively, and when the detection jig 110 is shifted to the detection station again, the position of the detection jig 110 may change relative to the workstation 100, and at this time, the image recognition module 200 can compare the position of the detection jig 110 corresponding to the workstation 100 currently with the position corresponding to the workstation 100 last time. When the difference exists between the two positions, the control module 500 can transmit the difference information to the adjusting module 310, the adjusting module 310 adjusts the current position of the module to be detected, so that the current position of the module to be detected is parallel to the current position of the detection jig 110, then the control module 500 controls the first transfer module 410 to operate, and the first transfer module 410 places the module to be detected adjusted by the adjusting module 310 in the detection jig 110 in parallel. Compare artifical scheme of dotting, this scheme is based on image recognition technology control adjustment module 310 adjustment and is waited the module position appearance that detects for it can accurately be shifted to in the detection tool 110 fast to wait to detect the module, and then improves the detection efficiency of module.

Considering that when the first transfer module 410 transfers the module to be detected to the detection fixture 110, there is a distance between the detection fixture 110 and the first transfer module 410, for this reason, researchers think that the first transfer module 400 is provided, and the first transfer module 410 is driven to move by the first transfer module 400, so as to improve the mobility of the first transfer module 410. Specifically, referring to fig. 1 and 3, the workbench 100 is further provided with a first conveying module 400, the control module 500 can control the first conveying module to operate, and the first transfer module 410 is disposed on the first conveying module 400 and is driven by the first conveying module 400 to move back and forth along a first direction, where the first direction is a direction pointed by an arrow a in fig. 1. The first transferring module 400 includes a linear motor 420, and the linear motor 420 drives the first transferring module 410 to move, but the transferring principle of the first transferring module 400 is not limited to this, and may also be implemented by a belt or a cylinder.

In order to improve the efficiency of placing the module to be detected on the adjustment module 310 when placing the module to be detected on the adjustment module 310, researchers think of setting the second transfer module 120 to complete the process. Specifically, referring to fig. 1, the workbench 100 is further provided with a second transferring module 120, wherein the second transferring module 120 can transfer the module to be detected to the adjusting module 310, and the control module 500 controls the second transferring module 120 to operate. It should be noted that the second transfer module 120 may be similar to the first transfer module 410, and the second transfer module 120 may also use, for example, a suction cup assembly to place the module to be detected on the adjustment module 310. In addition, the second transfer module 120 may also be disposed on the first transfer module 400 and be movable on the first transfer module 400.

Considering that if a single adjusting module 310 is used to adjust the pose of the module to be detected, the module to be detected can be placed after the adjusting module 310 finishes adjusting the pose and returns to the initial position, which affects the testing efficiency of the module to be detected. The researchers think of setting up a plurality of adjusting module 310 and working simultaneously, all place on every adjusting module 310 and wait to detect the module, when detecting the module test to same type, a plurality of adjusting module 310 can accomplish the adjustment of treating the detection module in step, so can improve the efficiency of testing that waits to detect the module. Specifically, referring to fig. 1 and 4, the workbench 100 is further provided with a second conveying module 300, the control module 500 controls the second conveying module 300 to operate, and the second conveying module 300 is provided with a plurality of adjusting modules 310 and is driven by the second conveying module 300 to move back and forth along a first direction. In this embodiment, after the detection fixture 110 is switched to the current position, the position of the detection fixture 110 is determined, and the adjusting modules 310 can respectively perform pose adjustment on the to-be-detected modules received by the detection fixture 110.

In view of the convenience that the image recognition module 200 can accurately determine the position of the detection jig 110 on the workbench 100 in time, in an embodiment, referring to fig. 5, each detection jig 110 of different models is provided with a different cross mark 111, and the image recognition module 200 recognizes the positions of the detection jigs 110 of different models relative to the workbench 100 according to the different cross marks 111. For example, when the inspection jig 110 is used for the first time, the position of the cross mark 111 on the inspection jig 110 relative to the workbench 100 is stored by the image recognition module, and when the inspection jig 110 is switched to the inspection station again for use, the image recognition module can judge whether the inspection jig 110 is used again according to the size of the cross mark 111, and judge the position difference between the cross mark 111 at the current position and the cross mark 111 at the last time according to the position of the current cross mark 111 relative to the workbench 100. The control module 500 controls the adjusting module 310 to adjust the pose information of the module to be detected according to the two difference information, so that the module to be detected can be parallel to the detecting tool 110.
