Abstract
Description
Technical Field
[0001] This application relates to the field of display module testing technology, and in particular to a display module testing device. Background Technology
[0002] Currently, smart displays are widely used in enterprises, homes, and social activities, with higher requirements for quality and appearance. Interactive screens are commonly seen in everyday life in electronic products such as mobile phones, computers, and tablets. During the production process of display screens, the display module typically undergoes optical performance testing and appearance defect detection during the pressing and bonding process. For example, gamma measurement is used to measure brightness and color coordinate data at different gray levels to calibrate the optical output performance of the display module, and AOI (Automated Optical Inspection) is used to identify appearance defects such as bright spots, dark spots, assembly defects, and surface damage.
[0003] Currently, during the inspection of display modules, the modules are first moved to a crimping station using a crimping fixture for crimping testing. After crimping, the modules are then sequentially transferred to the optical inspection station and the appearance inspection station. This process cannot simultaneously perform optical performance testing and appearance defect detection during the static crimping test of the display module. Furthermore, the movement of the display module can easily damage the crimping probes and lead to poor crimping. Utility Model Content
[0004] Therefore, it is necessary to provide a display module testing device to address the problem that it is impossible to simultaneously perform optical performance testing and appearance defect testing during the static pressing test of the display module.
[0005] A display module testing device includes a machine base, a pressing mechanism, a first testing mechanism, and a second testing mechanism, wherein the pressing mechanism, the first testing mechanism, and the second testing mechanism are all movably mounted on the machine base.

[0009] In one embodiment, the second detection mechanism includes a second drive module and an AOI detection module that is driven by the second drive module. The AOI detection module is disposed on the machine tool and can be moved to the detection station. The AOI detection module is used for detecting appearance defects of the display module.
[0010] In one embodiment, the machine tool also has a loading station and a unloading station;
[0011] The pressing mechanism includes a fixture module and a pressing head module. The fixture module is used to accommodate the display module. The fixture module is set on the machine base and can move between the loading station, the detection station and the unloading station.

[0012] In one embodiment, the fixture module includes an adjustment component and a platform pulsator connected to the adjustment component. The platform is disposed on the machine tool and is used to accommodate the display module. The adjustment component is used to adjust the position of the platform.
[0013] In one embodiment, the pressing mechanism further includes a third drive module, which is disposed on the machine base and is connected to the fixture module for transmission. The third drive module is used to drive the fixture module to move between the loading station and the position that cooperates with the pressing head module.
[0014] In one embodiment, the display module testing device further includes a loading mechanism and a unloading mechanism, both of which are disposed on the machine base. The loading mechanism can move to the loading station to load the display module onto the fixture module, and the unloading mechanism can move to the unloading station to accommodate the unloading of the display module in the fixture module.

[0016] The unloading mechanism includes a fifth drive module and an unloading arm that is driven by the fifth drive module. The unloading arm is disposed on the machine base and can move to the unloading station.
[0017] In one embodiment, the machine tool also has an alignment station;
[0018] The display module testing device further includes an alignment module, which is disposed on the machine tool and located at the alignment station;
[0019] The pressing mechanism can move between the feeding station, the alignment station, and the testing station.
[0020] In one embodiment, the pressing mechanism further includes a sixth drive module, which is disposed on the machine base and is connected to the fixture module for driving the fixture module to move between the loading station, the inspection station and the unloading station.
[0021] In the aforementioned display module testing device, when both the crimping mechanism and the first testing mechanism move to the testing station, the first testing mechanism can simultaneously perform optical performance testing on the display module during the static crimping process of the crimping mechanism.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0036] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0038] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.
[0039] See Figure 1 and Figure 2 As shown, this application provides a display module testing device 100, which includes a machine base 110, a pressing mechanism 120, a first testing mechanism 130, and a second testing mechanism 140. The pressing mechanism 120, the first testing mechanism 130, and the second testing mechanism 140 are all movably mounted on the machine base 110. The machine base 110 has a testing station 111, where display modules can be tested.
[0040] The crimping mechanism 120 is used to crimp the display module to establish electrical conductivity. The first inspection mechanism 130 is used for optical performance testing of the display module. For example, the first inspection mechanism 130 can be a gamma inspection mechanism, which can perform white balance pre-adjustment testing of the display module and collect brightness and color coordinate values of the display module at different gray levels to evaluate the optical performance of the display module. The second inspection mechanism 140 is used for appearance defect detection of the display module. For example, the second inspection mechanism 140 can be an AOI inspection mechanism, which uses a high-resolution camera to capture images of the display module surface and compares them with a standard template to capture appearance defects such as bright spots, dark spots, assembly defects, and surface damage. The crimping mechanism 120, the first inspection mechanism 130, and the second inspection mechanism 140 can all move to the inspection station 111. For example, when both the crimping mechanism 120 and the first inspection mechanism 130 move to the inspection station 111, the first inspection mechanism 130 can simultaneously inspect the optical performance of the display module during the static crimping process of the crimping mechanism 120, and when both the crimping mechanism 120 and the second inspection mechanism 140 move to the inspection station 111, the second inspection mechanism 140 can simultaneously inspect the appearance defects of the display module during the static crimping process of the crimping mechanism 120.
[0041] The aforementioned display module testing device 100, including the crimping mechanism 120, the first testing mechanism 130, and the second testing mechanism 140, can all be moved to the testing station 111. During the crimping and conduction process of the display module, optical performance testing and appearance defect testing can be performed simultaneously. Furthermore, the static crimping, optical performance testing, and appearance defect testing of the display module are all completed at the testing station 111. The display module does not need to move frequently, which will not cause damage to the probes of the crimping mechanism 120 or result in poor crimping, thereby improving the testing reliability of the display module.
[0042] In one embodiment, see Figures 1-3As shown, the first testing mechanism 130 includes a first driving module 131 and a Gamma probe module 132. The Gamma probe module 132 is disposed on the machine base 110 and is connected to the first driving module 131. The Gamma probe module 132 can move to the testing station 111 and is used for testing the optical performance of the display module. For example, in this embodiment, the first driving module 131 is a multi-axis adjustment module. When the pressing mechanism 120 drives the display module to the detection station 111, the first driving module 131 drives the Gamma probe module 132 to move to the detection station 111. When the Gamma probe module 132 is in the detection station 111, the first driving module 131 can adjust the position of the Gamma probe module 132 in the XYZ three-dimensional space to ensure that the Gamma probe module 132 is in a preset position and performs optical performance testing on the display module, ensuring the alignment accuracy between the Gamma probe module 132 and the display module, and improving the reliability of the optical performance testing of the Gamma probe module 132. After the optical performance testing of the display module is completed, the first driving module 131 drives the Gamma probe module 132 to a clearance position to avoid interference from the Gamma probe module 132 to subsequent operations of the display module.
[0043] It should be noted that in this embodiment, the first drive module 131 is a combination structure of a drive source, a slide rail and a slider. The slider is slidably disposed on the slide rail along the extension direction of the slide rail. The Gamma probe module 132 is disposed on the slider. The drive source outputs power to the slider to drive the Gamma probe module 132 to adjust its position in the XYZ three-dimensional space, thereby adjusting the relative position between the Gamma probe module 132 and the display module.
[0044] In one embodiment, see Figure 1 , Figure 2 and Figure 4As shown, the second inspection mechanism 140 includes a second drive module 141 and an AOI inspection module 142. The AOI inspection module 142 is mounted on the machine base 110 and is connected to the second drive module 141. The AOI inspection module 142 can move to the inspection station 111 and is used for the inspection of the appearance defects of the display module. For example, in this embodiment, the second drive module 141 is a multi-axis adjustment module. When the pressing mechanism 120 moves the display module to the inspection station 111, the second drive module 141 drives the AOI inspection module 142 to move to the inspection station 111. When the AOI inspection module 142 is at the inspection station 111, the second drive module 141 can adjust the position of the AOI inspection module 142 in the XYZ three-dimensional space to ensure that the AOI inspection module 142 is in a preset position and performs appearance defect detection on the display module, ensuring the alignment accuracy between the AOI inspection module 142 and the display module, and improving the reliability of appearance defect detection by the AOI inspection module 142. After the appearance defect detection of the display module is completed, the second drive module 141 drives the AOI inspection module 142 to a clearance position to avoid interference from the AOI inspection module 142 with subsequent operations of the display module.
[0045] It should be noted that in this embodiment, the AOI detection module 142 is a camera module. The camera module focuses and photographs the appearance defects at a preset position on the display module to detect appearance defects in the display module. The second drive module 141 is a combination structure of a drive source, a slide rail, and a slider. The slider is slidably mounted on the slide rail along its extension direction. The AOI detection module 142 is mounted on the slider. The drive source outputs power to the slider to drive the AOI detection module 142 to adjust its position in the XYZ three-dimensional space, thereby adjusting the relative position between the AOI detection module 142 and the display module.
[0046] In one embodiment, see Figure 1 , Figure 2 and Figure 5 As shown, the machine tool 110 also has a loading station 112 and a unloading station 113. The loading station 112 is for loading the display module, and the unloading station 113 is for unloading the display module. The pressing mechanism 120 includes a fixture module 121 and a pressing head module 122. The fixture module 121 is used to accommodate the display module. The fixture module 121 is disposed on the machine tool 110 and can move between the loading station 112, the inspection station 111, and the unloading station 113. The pressing head module 122 can cooperate with the fixture module 121 and is used to press the display module accommodated in the fixture module 121.
[0047] For example, when optical performance testing and appearance defect testing of a display module are required, firstly, the fixture module 121 moves to the loading station 112, and the display module to be tested is loaded onto the fixture module 121 at the loading station 112; then, the fixture module 121 moves to a position that mates with the pressure head module 122 and mates with the pressure head module 122; next, the pressure head module 122 and the fixture module 121 move synchronously to the testing station 111; continuing, the pressure head module 122 presses and connects the display module, and optical performance testing and appearance defect testing of the display module are performed at the testing station 111; finally, the fixture module 121 drives the tested display module to the unloading station 113, and the display module is unloaded at the unloading station 113.
[0048] Further, see Figure 1 , Figure 2 and Figure 5 As shown, the fixture module 121 includes an adjustment component 1211 and a stage 1212. The stage 1212 is disposed on the machine base 110 and is used to accommodate the display module. Exemplarily, the stage 1212 has a support cavity, which is a contoured cavity disposed on the stage 1212. The stage 1212 can fix the display module by adsorption to ensure the stability of the display module within the support cavity. Furthermore, the stage 1212 is a temperature-controlled stage, which can provide a preset environment for the display module when it is placed in the support cavity.
[0049] The stage 1212 is connected to the adjustment component 1211 via a transmission connection. The adjustment component 1211 is used to adjust the position and orientation of the stage 1212. For example, in this embodiment, the adjustment component 1211 includes an XYθ adjustment stage 1213 and a UVW adjustment stage 1214. The stage 1212 is disposed on the XYθ adjustment stage 1213, and the XYθ adjustment stage 1213 is disposed on the UVW adjustment stage 1214. The stage 1212 is indirectly disposed on the UVW adjustment stage 1214 via the XYθ adjustment stage 1213. Thus, the position and angular orientation of the stage 1212 can be adjusted in three-dimensional space via the XYθ adjustment stage 1213 and the UVW adjustment stage 1214, thereby improving the alignment accuracy between the display module and the first detection mechanism 130 and the second detection mechanism 140, and consequently improving the detection reliability of the display module.
[0050] Furthermore, see Figure 1 , Figure 2 and Figure 5As shown, the crimping mechanism 120 also includes a third drive module 123. The third drive module 123 is disposed on the machine base 110 and is connected to the fixture module 121 in a transmission manner. The third drive module 123 is used to drive the fixture module 121 to move between the loading station 112 and the position where the fixture module 121 and the pressing head module 122 are engaged. For example, when the third drive module 123 outputs power to the fixture module 121 and drives the fixture module 121 to move to the loading station 112, the fixture module 121 performs a loading operation at the loading station 112. After the display module is loaded onto the fixture module 121, the third drive module 123 continues to output power to the fixture module 121 and drives the fixture module 121 to move to a position that cooperates with the pressure head module 122. The pressure head module 122 cooperates with the fixture module 121 to conduct the display module contained in the fixture module 121.
[0051] The third drive module 123 may include, but is not limited to, power output components such as electric, pneumatic, and hydraulic systems. This application does not limit the specific type of components in the third drive module 123. Furthermore, the pressure head module 122 is connected to a drive element, which can drive the pressure head module 122 to move towards the display module housed within the fixture module 121, so that the pressure head module 122 can press against and conduct power to the display module. In this embodiment, the drive element may include, but is not limited to, power output components such as electric, pneumatic, and hydraulic systems. This application does not limit the specific type of drive element.
[0052] In one embodiment, see Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the display module testing device 100 also includes a loading mechanism 150 and a unloading mechanism 160, both of which are mounted on the machine base 110. The loading mechanism 150 can move to the loading station 112 and is used to load the display module into the fixture module 121. The unloading mechanism 160 can move to the unloading station 113 and is used to unload the display module into the fixture module 121.
[0053] For example, when the crimping and testing of the display module are required, the loading mechanism 150 and the fixture module 121 both move to the loading station 112. The loading mechanism 150 loads the display module to be tested onto the fixture module 121. The fixture module 121 moves the display module to the testing station 111 and performs the testing operation at the testing station 111. After the testing operation of the display module is completed, the fixture module 121 moves the display module to the unloading station 113. The unloading mechanism 160 moves to the unloading station 113 and performs the unloading operation on the tested display module.
[0054] Specifically, see Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the loading mechanism 150 includes a fourth drive module 151 and a loading arm 152. The loading arm 152 is disposed on the machine base 110 and is drivenly connected to the fourth drive module 151. The loading arm 152 can move to the loading station 112. Exemplarily, as in this embodiment, the fourth drive module 151 is a multi-axis adjustment module. The fourth drive module 151 can output power to the loading arm 152. The fourth drive module 151 can adjust the position of the loading arm 152 in the XYZ three-dimensional space so that the loading arm 152 can move to the loading station 112. The loading arm 152 performs the loading operation of the display module by means of adsorption, clamping, etc.
[0055] The unloading mechanism 160 includes a fifth drive module 161 and an unloading arm 162. The unloading arm 162 is disposed on the machine base 110 and is drivenly connected to the fifth drive module 161. The unloading arm 162 can move to the unloading station 113. For example, in this embodiment, the fifth drive module 161 is a multi-axis adjustment module. The fifth drive module 161 can output power to the unloading arm 162. The fifth drive module 161 can adjust the position of the unloading arm 162 in the XYZ three-dimensional space so that the unloading arm 162 can move to the unloading station 113. The unloading arm 162 performs the unloading operation of the display module by means of adsorption, clamping, etc.
[0056] It should be noted that in this embodiment, both the fourth drive module 151 and the fifth drive module 161 are combined structures of a drive source, a slide rail, and a slider. The slider is slidably disposed on the slide rail along the extension direction of the slide rail. The loading arm 152 and the unloading arm 162 are disposed on the corresponding sliders. The drive source outputs power to the sliders to drive the loading arm 152 and the unloading arm 162 to adjust their positions in the XYZ three-dimensional space, so that the loading arm 152 can perform loading operations at the loading station 112 and the unloading arm 162 can perform unloading operations at the unloading station 113.
[0057] In one embodiment, see Figure 1 , Figure 2 and Figure 7As shown, the machine tool 110 also has an alignment station 114. The display module testing device 100 further includes an alignment module 170, which is disposed on the machine tool 110. The pressing mechanism 120 can move between the loading station 112, the alignment station 114, and the testing station 111. Specifically, as in this embodiment, firstly, the pressing mechanism 120 moves to the loading station 112 and completes the loading operation of the display module at the loading station 112; then, the pressing mechanism 120 moves the display module to the alignment station 114, and the alignment module 170 takes pictures to align the position of the display module to ensure the positional accuracy of the display module; finally, the aligned display module moves to the testing station 111 through the pressing mechanism 120 and performs a testing operation at the testing station 111.
[0058] In this embodiment, the alignment module 170 can be a CCD camera (charge coupled device camera, industrial camera). When the pressing mechanism 120 moves the display module to the inspection station 111, the alignment module 170 performs alignment operations on the display module through visual positioning. Of course, in other feasible embodiments, the alignment module 170 can also be a position detection element such as an infrared sensor or a proximity sensor. This application does not limit the specific element type of the alignment module 170.
[0059] In one embodiment, see Figure 1 and Figure 2 As shown, the crimping mechanism 120 also includes a sixth drive module 124. The sixth drive module 124 is disposed on the machine base 110 and is connected to the fixture module 121 for transmission. The sixth drive module 124 is used to drive the fixture module 121 to move between the loading station 112, the inspection station 111 and the unloading station 113. For example, after the fixture module 121 loads the display module to be tested at the loading station 112, the sixth drive module 124 outputs power to the fixture module 121 and drives the fixture module 121 to move from the loading station 112 toward the testing station 111. After the fixture module 121 moves to the testing station 111, the display module performs optical performance testing and appearance defect testing at the testing station 111. After the display module testing is completed, the sixth drive module 124 continues to output power to the fixture module 121 and drives the fixture module 121 to move to the unloading station 113 to perform the unloading operation of the display module at the unloading station 113.
[0060] It should be noted that, in this embodiment, the sixth drive module 124 is a combination structure of a drive source, a slide rail and a slider. The slider is slidably disposed on the slide rail along the extension direction of the slide rail. The fixture module 121 is disposed on the slider. The drive source outputs power to the slider to drive the fixture module 121 to adjust its position in the XYZ three-dimensional space, so that the fixture module 121 can move between the loading station 112, the inspection station 111 and the unloading station 113.
[0061] The following combination Figures 1-7 The detection actions of the display module in this application are described in detail.
[0062] Step S110: Both the fixture module 121 and the feeding mechanism 150 move to the feeding station 112. The feeding mechanism 150 feeds the display module to be tested onto the fixture module 121. The fixture module 121 fixes the display module by adsorption.
[0063] Step S120: The fixture module 121 moves to the alignment station 114, and the alignment module 170 aligns the display module. When the position of the display module deviates, the XYθ adjustment stage 1213 and the UVW adjustment stage 1214 adjust the position and angle of the stage 1212 in three-dimensional space to ensure the position accuracy of the display module on the fixture module 121.
[0064] Step S130: The third drive module 123 drives the fixture module 121 to move to a position that engages with the pressure head module 122, so that the pressure head module 122 presses against the conductive display module.
[0065] Step S140: The sixth drive module 124 drives the fixture module 121 to move from the loading station 112 to the inspection station 111.
