Technical Field
[0001] This application relates to the field of product testing technology, and in particular to a display module edge detection device and testing equipment. Background Technology
[0002] Currently, smart displays are widely used in businesses, homes, and social activities, with higher requirements for quality and appearance. In daily life, we often see electronic products with interactive screens such as mobile phones, computers, and tablets. During the production process of display modules, their edges need to be inspected, especially for curved screens, to ensure that the curved edges meet production requirements.
[0003] Currently, display modules are typically transported from front to back along the transfer mechanism to the inspection station for edge detection. However, this type of inspection requires waiting for the previous product to be inspected before the edge detection of the next product can proceed, resulting in low inspection efficiency for display modules and long waiting times between processes, which seriously affects the edge detection efficiency of display modules.

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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.
[0038] See Figures 1-6As shown, this application provides a display module edge detection device 100, which includes a machine base 110, a feeding mechanism 120, a short side detection mechanism 130, a transfer mechanism 140, a long side detection mechanism 150, and a discharging mechanism 160. The feeding mechanism 120, the short side detection mechanism 130, the transfer mechanism 140, the long side detection mechanism 150, and the discharging mechanism 160 are arranged sequentially along the flow direction of the product to be inspected 200. The display module edge detection device 100 is used to detect the long and short sides of the product to be inspected 200. In this embodiment, the product to be inspected 200 is a display module. For example, the product to be inspected 200 can be a flat screen, a curved screen, or other irregularly shaped screen. The product to be inspected 200 includes a display module body, two short sides, and two long sides. The two short sides are located on both sides of the display module body along the length direction of the display module body, and the two long sides are located on both sides of the display module body along the width direction of the display module body. That is to say, the overall shape of the product to be inspected 200 is similar to a cuboid structure.
[0039] The machine tool 110 has a loading position 111, a transfer position 112, and a unloading position 113 arranged sequentially. For example, the loading position 111, the transfer position 112, and the unloading position 113 are arranged sequentially along the flow direction of the product 200 to be inspected. The loading position 111 is used for loading the product 200 to be inspected, the transfer position 112 is used for temporary storage of the product 200 to be inspected, and the unloading position 113 is used for unloading the product 200 to be inspected.
[0040] The feeding mechanism 120 can move between the feeding position 111 and the intermediate transfer position 112. The feeding mechanism 120 is used for feeding the product 200 to be inspected. For example, the feeding mechanism 120 can move along... Figure 2The feeding mechanism 120 moves in both directions a and b. When it moves along direction b to feeding position 111, it can feed the product 200 to be inspected. When it moves along direction a to transfer position 112, it can feed the product 200 to be inspected to the transfer position 112 for temporary storage. The short-side detection mechanism 130 is located between feeding position 111 and transfer position 112. The short-side detection mechanism 130 is used for short-side detection of the product 200 to be inspected. For example, during the process of feeding mechanism 120 carrying the product 200 to be inspected moving along direction a from feeding position 111 to transfer position 112, the short-side detection mechanism 130 can perform short-side detection on the product 200 to be inspected. The transfer mechanism 140 is located at transfer position 112. The transfer mechanism 140 is used to temporarily store the product 200 to be inspected. When the feeding mechanism 120 moves to transfer position 112, the feeding mechanism 120 can place the product 200 to be inspected after short-side inspection in the transfer mechanism 140 for temporary storage. The unloading mechanism 160 can move between unloading position 113 and transfer position 112. The unloading mechanism 160 is used to unload the product 200 to be inspected. For example, the unloading mechanism 160 can move along... Figure 2 The feeding mechanism 160 moves along both directions c and d. When the feeding mechanism 160 moves along direction c to the transfer station 112, it can receive the product 200 temporarily stored in the transfer station 140. When the feeding mechanism 160 moves along direction d to the feeding station 113, it can perform feeding operations on the product 200. The long-side detection mechanism 150 is located between the transfer station 112 and the feeding station 113. The long-side detection mechanism 150 is used for long-side detection of the product 200. For example, during the process of the feeding mechanism 160 moving the received product 200 from the transfer station 112 to the feeding station 113 along direction d, the long-side detection mechanism 150 can perform long-side detection operations on the product 200.
[0041] The aforementioned edge detection device 100 for the display module firstly involves the loading mechanism 120 loading the product 200 to be inspected at the loading position 111; secondly, the loading mechanism 120 moves the loaded product 200 to the transfer position 112, and during the movement of the loading mechanism 120, the short-side detection mechanism 130 performs short-side detection on the product 200; then, the transfer mechanism 140 temporarily stores the product 200 after the short-side detection is completed, and the loading mechanism 120 moves from the transfer position 112... 12. The feeding mechanism returns to the loading position 111 to continue the feeding action of the product 200 to be inspected, and the unloading mechanism 160 moves from the unloading position 113 to the transfer position 112 to receive the product. Finally, the unloading mechanism 160 receives the product 200 to be inspected temporarily stored at the transfer position 112, and the unloading mechanism 160 moves with the received product 200 to the unloading position 113. During the movement of the unloading mechanism 160, the long side detection mechanism 150 performs long side detection on the product 200 to be inspected during the movement. In this way, through the alternating movement of the loading mechanism 120 and the unloading mechanism 160, and in coordination with the transfer mechanism 140, the feeding, temporary storage and unloading actions of the product 200 to be inspected are carried out. The long side detection mechanism 150 and the short side detection mechanism 130 perform line scanning on the product 200 to be inspected during the movement to perform long and short side detection on the product 200 to be inspected. The loading mechanism 120 can immediately return to the loading position 111 after short side inspection to load the product 200 to be inspected. The unloading mechanism 160 can immediately return to the transfer position 112 after unloading to receive the product 200 to be inspected. That is, the loading, short side inspection and unloading, and long side inspection of the product 200 to be inspected are independent of each other, which shortens the loading and unloading time and the long and short side inspection time of the product 200 to be inspected, thereby improving the loading and unloading and inspection efficiency of the product 200 to be inspected.
[0042] In one embodiment, see Figures 1-3 As shown, the feeding mechanism 120 includes a first drive module 121 and multiple first support platforms 122. The first drive module 121 and the multiple first support platforms 122 are all connected by a drive mechanism. The first drive module 121 drives the multiple first support platforms 122 to move synchronously between the feeding position 111 and the transfer position 112. The first support platforms 122 are used to carry the products 200 to be inspected. Thus, the first drive module 121 enables the movement of the multiple first support platforms 122 between the feeding position 111 and the transfer position 112, thereby sending multiple products 200 to be inspected to the transfer position 112 for temporary storage. During the feeding process of the products 200 to be inspected from the feeding position 111 to the transfer position 112, the short-side detection mechanism 130 can perform short-side detection on the products 200, simultaneously completing the short-side detection of multiple products 200, thus improving the efficiency of short-side detection of the products 200.
[0043] In this embodiment, the first drive module 121 can be a linear motor, linear cylinder, or other drive element. This application does not limit the specific type of element in the first drive module 121. Furthermore, see [reference needed]. Figure 3 As shown, there are two first carrier platforms 122, which can simultaneously perform short-side inspection on two products 200 to be inspected. Of course, in other feasible embodiments, there can be three, four or other numbers of first carrier platforms 122. This application does not limit the specific number of first carrier platforms 122.
[0044] Specifically, see Figures 1-3 As shown, the first support platform 122 includes a first substrate 1221 and a first adsorption module 1222. The first adsorption module 1222 is disposed on the first substrate 1221 and is used to adsorb the product 200 to be inspected onto the first substrate 1221. For example, the first adsorption module 1222 may be an integration of a ventilation element and multiple adsorption holes. The multiple adsorption holes are arrayed on the first substrate 1221, and the ventilation element can blow negative pressure gas toward the multiple adsorption holes. By adsorbing the product 200 to be inspected onto the first substrate 1221 through negative pressure, the loading and adsorption operation of the product 200 to be inspected on the first support platform 122 is realized.
[0045] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the unloading mechanism 160 includes a second drive module 161 and multiple second support platforms 162. The second drive module 161 and the multiple second support platforms 162 are all connected by a transmission mechanism. The second drive module 161 drives the multiple second support platforms 162 to move synchronously between the unloading position 113 and the transfer position 112. The second support platforms 162 are used to carry the products 200 to be inspected. Thus, the second drive module 161 enables the movement of the multiple second support platforms 162 between the unloading position 113 and the transfer position 112, allowing for receiving multiple products 200 at the transfer position 112. During the feeding process of the products 200 from the transfer position 112 towards the unloading position 113, the long-side inspection mechanism 150 can perform long-side inspection on the products 200, simultaneously completing the long-side inspection of multiple products 200, thereby improving the long-side inspection efficiency of the products 200.
[0046] In this embodiment, the second drive module 161 can be a linear motor, linear cylinder, or other drive element. This application does not limit the specific type of element in the second drive module 161. Furthermore, see [link to relevant documentation]. Figure 4As shown, there are two second carrier platforms 162, which can simultaneously perform long-side inspection of two products 200 to be inspected. Of course, in other feasible embodiments, there can be three, four or other numbers of second carrier platforms 162. This application does not limit the specific number of second carrier platforms 162.
[0047] Specifically, see Figure 1 , Figure 2 and Figure 4 As shown, the second carrier platform 162 includes a second substrate 1621 and a second adsorption module 1622. The second adsorption module 1622 is disposed on the second substrate 1621 and is used to adsorb the product 200 to be inspected onto the second substrate 1621. For example, the second adsorption module 1622 may be an integration of a ventilation element and multiple adsorption holes. An array of multiple adsorption holes is disposed on the second substrate 1621, and the ventilation element can blow negative pressure gas toward the multiple adsorption holes. The negative pressure adsorbs the product 200 to be inspected onto the second substrate 1621, thus realizing the receiving and adsorption operation of the product 200 on the second carrier platform 162.
[0048] Further, see Figure 1 , Figure 2 and Figure 4 As shown, the unloading mechanism 160 also includes a rotating module 1623, which is connected to the second base 1621 via a transmission connection. The rotating module 1623 is used to drive the rotation of the second base 1621. Since the long side and short side of the product to be inspected 200 are located in two different directions, after the product to be inspected 200 has undergone short side inspection and is temporarily stored in the transfer mechanism 140, and after the unloading mechanism 160 receives the product to be inspected 200, the rotating module 1623 rotates the product to be inspected 200 by a certain angle, so that the long side of the product to be inspected 200 faces the position where the long side inspection mechanism 150 can collect and capture images, thereby realizing the operation of switching the product to be inspected 200 from short side inspection to long side inspection.
[0049] Of course, as in one embodiment, see [reference] Figures 1-4 As shown, a rotating module 1623 is provided in the feeding mechanism 120. The rotating module 1623 is connected to the first base 1221 and is used to drive the rotation of the first base 1221. After the product to be inspected 200 has undergone short-side inspection, the rotating module 1623 rotates the product to be inspected 200 by a certain angle and temporarily stores it in the transfer mechanism 140, realizing the operation of switching the product to be inspected 200 from short-side inspection to long-side inspection. As in another embodiment, see [reference needed]. Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a rotating module 1623 is provided in the transfer mechanism 140. The rotating module 1623 is connected to the third adsorption module 143 and is used to drive the rotation of the third adsorption module 143. When the product to be inspected 200 is temporarily stored in the transfer mechanism 140, the rotating module 1623 rotates the product to be inspected 200 by a certain angle and temporarily stores it in the transfer mechanism 140, realizing the operation of switching the product to be inspected 200 from short side inspection to long side inspection.
[0050] In this embodiment, the rotating module 1623 can be a driving element such as a rotating motor or a rotating cylinder. This application does not limit the specific type of component in the rotating module 1623.
[0051] In one embodiment, see Figure 1 , Figure 2 and Figure 5 As shown, the transfer mechanism 140 includes a bracket 141, a third drive module 142, and multiple third adsorption modules 143. The bracket 141 is mounted on the machine base 110 by welding, screwing, or other methods, thus fixing the transfer mechanism 140 to the machine base 110. Multiple third adsorption modules 143 are mounted on the bracket 141. The third adsorption modules 143 are used to adsorb the product 200 to be inspected. The third drive module 142 is connected to the third adsorption modules 143 by transmission, and the third drive module 142 drives the third adsorption modules 143 to move towards or away from the flow plane of the product 200 to be inspected. For example, when the feeding mechanism 120 feeds the product to be inspected 200 to the transfer position 112, the third drive module 142 drives the third adsorption module 143 to move toward the flow plane of the product to be inspected 200, and the third adsorption module 143 adsorbs the product to be inspected 200 after the short side detection. After the third adsorption module 143 adsorbs and temporarily stores the product to be inspected 200, the third drive module 142 drives the third adsorption module 143 to move away from the flow plane of the product to be inspected 200, so as to avoid the third adsorption module 143 interfering with the movement of the feeding mechanism 120 back to the feeding position 111. Similarly, when the unloading mechanism 160 moves to the intermediate position 112, the third drive module 142 drives the third adsorption module 143 to move towards the flow plane of the product to be inspected 200 and releases the temporarily stored product to be inspected 200 to the unloading mechanism 160. After the product to be inspected 200 adsorbed by the third adsorption module 143 is released to the unloading mechanism 160, the third drive module 142 drives the third adsorption module 143 to move away from the flow plane of the product to be inspected 200, so as to avoid the third adsorption module 143 interfering with the movement of the unloading mechanism 160 back to the unloading position 113.
[0052] In this embodiment, the third drive module 142 can be a linear motor, linear cylinder or other drive element. This application does not limit the specific element type of the third drive module 142.
[0053] In one embodiment, see Figure 1 , Figure 2 and Figure 6 As shown, both the short-side detection mechanism 130 and the long-side detection mechanism 150 include two line scanning modules 170, which are spaced apart along the flow direction of the product 200 to be inspected. Thus, during the movement of the loading mechanism 120 from the loading position 111 to the transfer position 112, the two line scanning modules 170 in the short-side detection mechanism 130 can respectively detect the two short sides of the product 200 to be inspected; and during the movement of the unloading mechanism 160 from the transfer position 112 to the unloading position 113, the two line scanning modules 170 in the long-side detection mechanism 150 can respectively detect the two long sides of the product 200 to be inspected.
[0054] Furthermore, the line scanning module 170 includes a frame 171, an adjustment component 172, and at least one camera 173. The frame 171 is mounted on the machine base 110 by welding, screwing, or other methods to achieve the installation and fixation of the line scanning module 170 on the machine base 110. The camera 173 is movably mounted on the frame 171 and is used to collect edge defects of the product under inspection 200. The adjustment component 172 is used to adjust the angle and position of the camera 173. In this way, by adjusting the angle and position of the camera 173 relative to the frame 171 through the adjustment component 172, the camera 173 can focus on the preset edge position of the product under inspection 200 for acquisition and imaging, improving the adjustment freedom of the line scanning module 170. Moreover, for different specifications of the product under inspection 200 or different detection positions of the product under inspection 200, the angle and position of the camera 173 can be adjusted to adapt to the long and short side detection operations of different specifications of the product under inspection 200 or different detection positions of the product under inspection 200, expanding the application scenarios of the display module edge detection device 100.
[0055] Preferably, the line scan module 170 contains multiple cameras 173, as shown in this embodiment, see reference. Figure 6 As shown, the line scan module 170 has three cameras 173, which can be used to perform comprehensive inspection of the edges of the product 200 to be inspected, thereby improving the reliability of the line scan module 170 in inspecting the product 200.
[0056] Specifically, see Figure 1 , Figure 2 and Figure 6As shown, the adjustment assembly 172 includes an adjustment plate 1721, an X-axis sliding module 1722, and a Z-axis sliding module 1723. The adjustment plate 1721 is slidably mounted on the frame 171 via the X-axis sliding module 1722 and the Z-axis sliding module 1723. The adjustment plate 1721 is provided with an arc-shaped groove 1724, and the camera 173 is disposed in the arc-shaped groove 1724, and the camera 173 can slide along the extension direction of the arc-shaped groove 1724. Thus, the X-axis position of the camera 173 can be adjusted by the X-axis sliding module 1722, and the Z-axis position of the camera 173 can be adjusted by the Z-axis sliding module 1723. Furthermore, the angle of the camera 173 can be adjusted by sliding the camera 173 within the arc-shaped groove 1724. In other words, the adjustment component 172 can adjust the camera 173 with multiple degrees of freedom to adapt to the long and short side detection operations of different specifications of the product to be inspected 200 or different detection positions of the product to be inspected 200, thereby expanding the application scenarios of the display module edge detection device 100.
[0057] Preferably, the adjustment assembly 172 further includes a driving element, which is connected to the X-axis sliding module 1722, the Z-axis sliding module 1723 and the camera 173. The driving element enables the automatic adjustment of the camera 173, avoiding adjustment errors caused by manual adjustment and improving the reliability of the position and angle adjustment of the camera 173.
[0058] In one embodiment, see Figure 1 , Figure 2 and Figure 7 As shown, the display module edge detection device 100 also includes a transfer mechanism 180, which is disposed on the machine base 110 and located at the unloading position 113. The transfer mechanism 180 is used to transfer the product 200 to be inspected after long-side detection to the next process. Exemplarily, the transfer mechanism 180 includes a fourth drive module 181 and a fourth adsorption module 182. The fourth drive module 181 drives the fourth adsorption module 182 to perform the unloading operation of the product 200 to be inspected on the unloading mechanism 160 at the unloading position 113. In this embodiment, the fourth drive module 181 can be a linear motor, linear cylinder, or other drive element. This application does not limit the specific type of element in the fourth drive module 181.
[0059] Additionally, see Figures 1-6 As shown, this application also provides a testing device, which includes a display module edge detection device 100 as described above. The testing device can perform loading / unloading and long / short side detection operations on the product 200 to be inspected.
[0060] The aforementioned testing equipment, firstly, the feeding mechanism 120 can feed the product to be inspected 200 at the feeding position 111; secondly, the feeding mechanism 120 moves the product to be inspected 200 to the transfer position 112, and during the movement of the feeding mechanism 120, the short-side detection mechanism 130 performs short-side detection on the product to be inspected 200; then, the transfer mechanism 140 temporarily stores the product to be inspected 200 after the short-side detection is completed, and the feeding mechanism 120 returns from the transfer position 112. Material station 111 continues the loading action of product 200 to be inspected, and unloading mechanism 160 moves from unloading station 113 to transfer station 112 to receive the product. Finally, unloading mechanism 160 receives product 200 temporarily stored at transfer station 112, and moves with the received product 200 to unloading station 113. During the movement of unloading mechanism 160, long side detection mechanism 150 performs long side detection on product 200 during the movement. Thus, through the alternating movement of loading mechanism 120 and unloading mechanism 160, and in coordination with transfer mechanism 140, the loading, temporary storage and unloading actions of product 200 to be inspected are carried out. Long side detection mechanism 150 and short side detection mechanism 130 perform line scanning on product 200 during the movement to perform long and short side detection of product 200. The loading mechanism 120 can immediately return to the loading position 111 after short side inspection to load the product 200 to be inspected. The unloading mechanism 160 can immediately return to the transfer position 112 after unloading to receive the product 200 to be inspected. That is, the loading, short side inspection and unloading, and long side inspection of the product 200 to be inspected are independent of each other, which shortens the loading and unloading time and the long and short side inspection time of the product 200 to be inspected, thereby improving the loading and unloading and inspection efficiency of the product 200 to be inspected.
[0061] The following combination Figures 1-7 The loading and unloading and long / short side detection operations of the display module edge detection device 100 provided in this application are described in detail, with two examples of the first bearing platform 122, the second bearing platform 162 and the third adsorption module 143.
[0062] First, the feeding mechanism 120 moves to the feeding position 111 to feed two products 200 to be inspected. Second, the feeding mechanism 120, carrying the two products 200, moves along direction a to the transfer position 112. During this movement, the short-side detection mechanism 130 performs short-side detection on the products 200. Next, the transfer mechanism 140 absorbs and temporarily stores the two products 200 after the short-side detection. The feeding mechanism 120 then returns from the transfer position 112 to the feeding position 111 along direction b to continue feeding the products 200, while the unloading mechanism 160 moves along direction c from the unloading position 113 to the transfer position 112. The material receiving action is performed; continuing, the unloading mechanism 160 receives two products 200 temporarily stored in the transfer station 112. The unloading mechanism 160 carries the two products 200 to be inspected along the d direction from the transfer station 112 toward the unloading station 113. Before the unloading mechanism 160 passes the long side detection mechanism 150, the rotating module 1623 rotates the products 200 to be inspected. When the unloading mechanism 160 passes the long side detection mechanism 150, the long side detection mechanism 150 performs long side detection on the products 200 during the movement. Finally, the unloading mechanism 160 moves to the unloading station 113, and the transfer mechanism 180 transfers the products 200 to the next process after the long side detection.
