[0001] The present invention relates to the technical field of optical detection equipment, and in particular to an automatic detection device. Background Art

[0002] The display panel, or LCD screen, largely determines the brightness, contrast, color and viewing angle of the LCD monitor. Its quality is not only related to the quality, price and market trend of the LCD monitor itself, but also to the functional parameters, display effects and service life of the entire product.

[0003] In every link of production, display panels may have production defects that lead to unqualified products. Therefore, it is extremely important to strictly inspect display panels during the production process. The inspection of display panels sometimes involves two aspects: (1) using automatic optical inspection (AOI) equipment to analyze whether the image of the display panel to be tested is consistent with the standard image; (2) using automatic stroboscopic inspection equipment to analyze the brightness, chromaticity, and uniformity of the brightness and chromaticity of the image displayed by the display panel. Currently, when inspecting display panels, two devices are usually used to perform AOI inspection and automatic stroboscopic inspection respectively. Due to the long inspection time and the time-consuming feeding and unloading, the working efficiency of the display panel production line is low. Summary of the invention

[0004] The object of the present invention is to provide an automatic inspection device capable of performing AOI and automatic stroboscopic inspection on a display panel, so as to shorten the working time of feeding and unloading and improve the production efficiency of a display panel production line.

[0011] As a preferred solution of the automatic detection device, the light box module includes an upper light box and a lower light box arranged one above the other, and the upper light box and the lower light box are respectively slidably connected to the base.

[0012] As a preferred solution of the automatic detection device, a synchronous lifter is provided on the lower light box for driving the lower light box to move in a vertical direction.

[0034] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, not all.

[0035] In the description of the present invention, it should be noted that the terms "horizontal", "vertical", etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] like Figure 1 As shown, this embodiment provides an automatic detection device, which includes a base 1 and a light box module 5. The light box module 5 is slidably connected to the base 1, and the light box module 5 is used to place the display panel to be tested. An AOI detection station S and an automatic strobe detection station F are arranged on the sliding track of the light box module 5, an AOI detection module 2 is arranged above the AOI detection station S, and an automatic strobe detection module 3 is arranged above the automatic strobe detection station F. The display panel is placed on the light box module 5, and the AOI detection station S and the automatic strobe detection station F are arranged on the sliding track of the light box module 5 along the base 1, so that the AOI and automatic strobe detection of the display panel can be completed by one device, which overcomes the characteristic that two large-scale detection devices need to be set up on the traditional display panel production line, saves the floor space of the equipment, improves the equipment utilization rate, and saves the working hours of feeding and unloading, which greatly improves the production efficiency of the display panel production line.

[0037] In order to realize automatic loading and unloading operation, in this embodiment, the automatic detection device further includes a loading and unloading station L, which is located between the AOI detection station S and the automatic strobe detection station F. By arranging the loading and unloading station L between the AOI detection station S and the automatic strobe detection station F, it is convenient to load and unload the display panel to be tested on the light box module 5, and also shortens the moving distance of the light box module 5 when it moves cyclically on the AOI detection station S and the automatic strobe detection station F, which can save detection time and improve work efficiency.

[0038] Furthermore, a loading and unloading mechanism 4 is provided above the loading and unloading station L, such as Figure 2 As shown, the loading and unloading mechanism 4 includes a loading and unloading rack 41 disposed above the base 1 and a manipulator slidably connected to the loading and unloading rack 41. The loading and unloading rack 41 is disposed above the base 1 and a space is left between the base 1 to enable the light box module 5 to slide in the horizontal direction. Specifically, in this embodiment, the loading and unloading rack 41 is fixedly connected to the base 1 by a connecting member 44, so that the stability of the loading and unloading process can be achieved. In addition to fixing the loading and unloading rack 41 on the base 1, other methods that can realize the loading and unloading rack 41 being disposed above the base 1 and can complete the loading and unloading operation of the display panel on the light box module 5 can be adopted. In addition, in this embodiment, a loading and unloading rack 41 is provided with a loading manipulator 42 for completing the loading operation and a unloading manipulator 43 for completing the unloading operation. By providing the loading manipulator 42 and the unloading manipulator 43, and arranging the loading manipulator 42 and the unloading manipulator 43 on opposite sides of the loading and unloading rack 41, the loading operation and the unloading operation can be made independent of each other, which is conducive to improving the operation efficiency. Of course, in other embodiments, a manipulator that can simultaneously complete the loading and unloading operations can also be provided on the loading and unloading rack 41.

[0039] Furthermore, an automatic stroboscopic detection module 3 is provided on the loading and unloading rack 41, such as Figure 3As shown, the automatic strobe detection module 3 includes a test probe, a fixing member 33 for fixing the test probe, and a lifting cylinder, wherein the test probe is used to perform automatic strobe detection on the display panel to be tested, so as to analyze whether the brightness, chromaticity, and uniformity of brightness and chromaticity of the image displayed by the display panel to be tested are qualified. The output end of the lifting cylinder is connected to the fixing member 33, which is used to drive the lifting of the test probe so as to adjust the distance between the test probe and the display panel to be tested, so as to better complete the automatic strobe detection of the display panel to be tested. In this embodiment, in order to better fix the lifting cylinder, a fine-tuning seat 36 is fixedly provided on the loading and unloading rack 41, and the lifting cylinder is fixedly provided on the fine-tuning seat 36. Of course, in other embodiments, the lifting cylinder can also be directly provided on the loading and unloading rack 41. In addition, other methods that can realize that the automatic strobe detection module 3 is arranged above the automatic strobe detection station F and can realize automatic strobe detection of the display panel to be tested placed on the light box module 5 can be adopted.

[0040] Furthermore, the automatic strobe detection module 3 includes at least two groups of test probes, a fixing member 33 and a lifting cylinder, wherein one group of test probes is arranged around another group of test probes, and the two groups of test probes are respectively used to detect the center and edge of the display panel to be tested. Figure 4 As shown, in this embodiment, the test probe includes a first test probe 31 disposed on the first fixing member and a second test probe 32 disposed on the second fixing member, the first test probe 31 is used to detect the center of the display panel to be tested, and the second test probe 32 is used to detect the edge of the display panel to be tested, and the lifting cylinder includes a first lifting cylinder 34 and a second lifting cylinder 35, the first lifting cylinder 34 is used to drive the lifting of the first test probe 31, and the second lifting cylinder 35 is used to drive the lifting of the second test probe 32. For an ordinary display panel to be tested, only the first test probe 31 disposed at the center of the fixing member 33 is needed to perform automatic stroboscopic detection on the display panel to be tested, but for a display panel to be tested with higher product quality requirements, the first test probe 31 and the second test probe 32 need to be used simultaneously for automatic stroboscopic detection. In this embodiment, four second test probes 32 are arranged at the edge of the fixing member 33 to detect the four corners of the display panel to be tested respectively. Of course, in other embodiments, the number of the second test probes 32 can also be adjusted according to the actual detection operation, and the number can be an integer of 1 or more, so as to achieve more accurate automatic stroboscopic detection of the display panel to be tested.

[0041] Furthermore, if Figure 5As shown, the AOI detection module 2 includes a stand 24 and an AOI detection component, wherein the stand 24 is vertically fixed on the base 1, and a lifting guide rail 23 is provided on the stand 24. The AOI detection component is slidably connected to the stand 24 through the lifting guide rail 23, and can move in the vertical direction to adjust the distance between the AOI detection component and the display panel to be tested, so as to better complete the AOI detection of the display panel to be tested. Specifically, the AOI detection component includes a plurality of AOI detection cameras 21 and an image collector 22, and the AOI detection camera 21 is communicatively connected with the image collector 22. When the display panel to be tested is subjected to AOI detection, the image information of the display panel to be tested is collected by the AOI detection camera 21, and then the collected data is transmitted to the image collector 22 for analysis to analyze whether the collected image is consistent with the standard image.

[0042] In order to improve the inspection efficiency of the production line and prevent one of the AOI inspection module 2 or the automatic strobe inspection module 3 from being in a waiting state for a long time, the light box module 5 is provided with an upper light box 51 and a lower light box 52 arranged up and down, and the upper light box 51 and the lower light box 52 are respectively slidably connected to the base 1. When the upper light box 51 is located at one of the AOI inspection station S and the automatic strobe inspection station F, the lower light box 52 is located at the other of the two. Specifically, when the automatic inspection device is in the first state, the upper light box 51 is located at the AOI inspection station S, and the lower light box 52 is located at the automatic strobe inspection station F; when the automatic inspection device is in the second state, the lower light box 52 is located at the AOI inspection station S, and the upper light box 51 is located at the automatic strobe inspection station F. By providing an upper light box 51 and a lower light box 52 arranged vertically on the automatic detection device, the upper light box 51 and the lower light box 52 cyclically move between the loading and unloading station L, the AOI detection station S and the automatic strobe detection station F in sequence, so as to complete the alternating AOI detection and automatic strobe detection of the display panels to be tested placed on the upper light box 51 and the lower light box 52, thereby greatly improving the utilization rate of the equipment.

[0043] Furthermore, a first transmission mechanism 11 and a second transmission mechanism 12 are arranged vertically on the base 1. Figure 6-Figure 7As shown, the upper light box 51 is slidably connected to the first transmission mechanism 11, and the first transmission mechanism 11 is used to realize horizontal movement; the lower light box 52 is slidably connected to the second transmission mechanism 12, and the second transmission mechanism 12 is used to realize horizontal movement. In this embodiment, the first transmission mechanism 11 is a first linear motor 111, and the two ends of the upper light box 51 are respectively fixedly connected to the first connecting block 112 provided on the first linear motor 111; the second transmission mechanism 12 is a second linear motor 121, and the two ends of the lower light box 52 are respectively fixedly connected to the second connecting block 122 provided on the second linear motor 121. The provision of linear motors can save a large number of intermediate transmission mechanisms, speed up the reaction speed of the transmission mechanism, and improve the transmission speed of the transmission mechanism. Of course, in other embodiments, the first transmission mechanism 11 and the second transmission mechanism 12 can be rotary motors driving the lead screw slider to realize the horizontal movement of the upper light box 51 and the lower light box 52. In addition, any method that can realize the horizontal movement of the upper light box 51 and the lower light box 52 can be adopted.

[0044] like Figure 6 As shown, the upper light box 51 includes a first jig module 511, and a first automatic crimping jig 513 is arranged on the first jig module 511. The first automatic crimping jig 513 can automatically crimp the display panel to be tested placed on the upper light box 51, so as to ensure that the display panel to be tested is accurately fixed on the first jig module 511 and can connect the detection signal. In this embodiment, two first automatic crimping jigs 513 are arranged on the first jig module 511, and two display panels to be tested can be placed on the upper light box 51 at the same time, so that the upper light box 51 can complete AOI detection and automatic strobe detection on the two display panels to be tested by moving once between the loading and unloading station L, the AOI detection station S and the automatic strobe detection station F. When performing AOI inspection on the liquid crystal module to be tested, in order to provide lighting for the AOI inspection module 2, a first auxiliary lighting lamp 512 is arranged around the first fixture module 511. In addition, a lighting lamp is also arranged on the stand 24 to provide sufficient lighting for the AOI inspection module 2.

[0045] like Figure 7As shown, the lower light box 52 includes a second jig module 521, and a second automatic crimping jig 523 is arranged on the second jig module 521. The second automatic crimping jig 523 can automatically crimp the display panel to be tested placed on the lower light box 52, so as to ensure that the display panel to be tested is accurately fixed on the first jig module 511 and can connect the detection signal. In this embodiment, two second automatic crimping jigs 523 are arranged on the second jig module 521, and two display panels to be tested can be placed on the lower light box 52 at the same time, so that the lower light box 52 can complete AOI detection and automatic strobe detection on the two display panels to be tested by moving once between the loading and unloading station L, the AOI detection station S and the automatic strobe detection station F. Second auxiliary lighting lamps 522 are arranged around the second jig module 521. Specifically, when the display panel to be tested placed on the upper light box 51 completes the AOI inspection and moves horizontally toward the automatic strobe detection module 3 along the first transmission mechanism 11, the lower light box 52 moves horizontally to the bottom of the loading and unloading rack 41 under the drive of the second transmission mechanism 12, and moves horizontally to the bottom of the AOI detection module 2 after completing the loading operation, thereby realizing the AOI inspection of the display panel to be tested placed on the lower light box 52. In order to ensure the synchronous lifting of the two ends of the lower light box 52, a synchronous lifter 524 is also provided on the second fixture module 521, which is used to drive the two ends of the lower light box 52 to maintain horizontal lifting, which can improve the horizontality of the lower light box 52 during the lifting process, so as to avoid the lower light box 52 from tilting during the lifting process, which affects the detection result of the display panel to be tested placed thereon.

[0046] In order to further improve the working efficiency of the production line, multiple groups of workbenches can be arranged on the base 1, and each group of workbenches is provided with an AOI detection module 2, an automatic strobe detection module 3 and a light box module 5. Multiple groups of workbenches work separately without affecting each other, and perform AOI and automatic strobe detection on multiple different display panels to be tested at the same time, so that the automated production line of the display panel can operate quickly and continuously. In this embodiment, two groups of workbenches are arranged on the base 1, and each group of workbenches includes an AOI detection module 2, an automatic strobe detection module 3 and a light box module 5. Of course, in other embodiments, the number of workbenches arranged on the base 1 can be 3 or more groups.

[0047] Furthermore, a maintenance channel 6 and a maintenance station R are also provided on the base 1. The maintenance channel 6 is provided between the two groups of workbenches, so as to facilitate the maintenance of the AOI detection module 2, the automatic strobe detection module 3 and the light box module 5 provided on the two groups of workbenches. In addition, when the upper light box 51 or the lower light box 52 on one group of workbenches needs to be inspected or repaired, the upper light box 51 or the lower light box 52 on the group of workbenches can be moved to the maintenance station R for inspection or maintenance, while the modules on the other group of workbenches can operate normally, thereby avoiding the production line stopping and affecting the production efficiency.

[0048] In order to make the workflow of the present invention clearer, a group of workbenches is taken as an example to illustrate the specific workflow of the present invention:

[0049] In the first step, the upper light box 51 slides horizontally to the bottom of the loading and unloading rack 41 through the first transmission mechanism 11, and the first display panel to be tested is placed on the upper light box 51 through the loading manipulator 42. After the loading operation is completed, the upper light box 51 slides horizontally to the bottom of the AOI inspection module 2 to perform AOI inspection on the first display panel to be tested;

[0050] In the second step, after the first display panel to be tested completes the AOI inspection, the upper light box 51 slides horizontally to the bottom of the automatic stroboscopic inspection module 3 to perform automatic stroboscopic inspection on the first display panel to be tested. At the same time, the lower light box 52 slides horizontally to the bottom of the loading and unloading rack 41, and the second display panel to be tested is placed on the lower light box 52 by the loading manipulator 42. After the loading operation is completed, the lower light box 52 slides horizontally to the bottom of the AOI inspection module 2 to perform AOI inspection on the second display panel to be tested;

[0051] In the third step, after the first display panel to be tested completes the automatic stroboscopic detection, the first display panel to be tested is taken out from the upper light box 51 by the unloading robot 43 and placed in the downstream workstation. At this time, the second display panel to be tested has completed the AOI detection, and the lower light box 52 slides horizontally to the bottom of the automatic stroboscopic detection module 3 to perform automatic stroboscopic detection on the second display panel to be tested. At the same time, the upper light box 51 slides horizontally to the bottom of the loading and unloading rack 41, and the third display panel to be tested is placed on the upper light box 51 by the loading robot 42. After completing the loading operation, the upper light box 51 slides horizontally to the bottom of the AOI detection module 2 to perform AOI detection on the third display panel to be tested, and so on.

[0052] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
