Abstract
Description
Technical Field
[0001] This application relates to the field of display device manufacturing technology, and in particular to a fixture for detecting the bending position of flexible circuit boards. Background Technology
[0002] Currently, in pursuit of narrow or borderless designs, display devices (such as computers, mobile phones, and televisions) have extremely limited bending points between the flexible printed circuit board (FPC) and the frame. Even slight deviations can cause the circuitry on the flexible printed circuit board to be damaged by the frame. Therefore, it is necessary to inspect the bending point of the flexible printed circuit board after bending.
[0003] There are two types of structures for display components after bending existing flexible circuit boards. The structure of the first display component 20 is as follows: Figure 1 and Figure 2 As shown, the first glass plate 21 is connected to the first display module 23 via the first optical adhesive 22, and the first flexible circuit board 25 is bent and connected to the first rigid circuit board 24. The maximum distance between the bending position of the first flexible circuit board 25 and the edge of the first glass plate 21 is W1. When the first frame 26 is installed on the first glass plate 21, it prevents the first frame 26 from damaging the circuit on the first flexible circuit board 25. Currently, the bending position of the first flexible circuit board 25 is checked by setting a first alignment line 211 on the first glass plate 21 and observing the first alignment line 211 with the human eye. If the bending position of the first flexible circuit board 25 does not exceed the first alignment line 211, it is considered qualified. The structure of the second display component 30 is as follows. Figure 3 and Figure 4 As shown, the second glass plate 31 is connected to the second display module 33 via the second optical adhesive 32, and the second flexible circuit board 35 is connected to the second rigid circuit board 34 after bending. The maximum distance between the bending position of the second flexible circuit board 35 and the edge of the second glass plate 31 is W2. When the second adhesive frame 36 is installed on the decorative part 37, it is to prevent the second adhesive frame 36 from damaging the circuit on the second flexible circuit board 35. Currently, the bending position of the second flexible circuit board 35 is checked by setting a second alignment line 351 on the second flexible circuit board 35 and observing the second alignment line 351 with the human eye. The second alignment line 351 on the second flexible circuit board 35 is considered to be qualified if it does not exceed the edge of the second glass plate 31.
[0004] However, both of the above detection methods rely on human eye observation. Due to the variable perspective of human observation and human subjectivity, the detection results are prone to deviation. Utility Model Content

Compared with human eye detection, the detection position is determined and human subjectivity is avoided, reducing or even eliminating the deviation of the detection results; moreover, it eliminates the need to set alignment lines on the glass plate or flexible circuit board, reducing the production steps of the display component and improving the production efficiency of the display component.

[0048] An embodiment of the first aspect of this application provides a fixture for detecting the bending position of a flexible circuit board. Please also refer to... Figure 1 and Figure 2 The flexible circuit board bending position detection fixture 10 includes a mounting platform 11, a first driving device 12, and a detection element 13. The mounting platform 11 is provided with a mounting position 111 for positioning and installing a display component. The first driving device 12 is mounted on the mounting platform 11, and the first driving device 12 and the mounting position 111 are arranged in the second direction Y. The detection element 13 is connected to the first driving device 12, and the first driving device 12 is used to drive the detection element 13 to move along the first direction X. The first direction X is perpendicular to the second direction Y.
[0049] The structure of the mounting platform 11 is not limited in this application. For example, the mounting platform 11 can be a box structure or a frame structure. When the mounting platform 11 is a box structure, its shape can be a cuboid, a cylinder, an elliptical cylinder, etc.
[0050] Mounting position 111 is used to position and install the display component. This means that after the display component is installed on mounting position 111, the relative position between the display component and the detection element 13 meets the detection requirements, and the display component will not move during the detection process. The display component can be... Figure 1 The first display component 20 in the middle can also be Figure 2 The second display component 30 in the middle.
[0051] The first driving device 12 is mounted on the mounting platform 11. This can be understood as the first driving device 12 being fixed to the mounting platform 11 by means of fastener connection, welding, snap-fit, interference fit, etc. The structure of the first driving device 12 is not limited in this application, as long as it can drive the detection component 13 to move along the first direction X. Here, the first direction X is the width direction of the flexible circuit board.
[0052] It is understood that the first drive device 12 may include a drive motor 122 and a lead screw and nut mechanism 121 connected to the drive motor 122, or the first drive device 12 may also be a telescopic cylinder or an electric push rod.
[0053] Optionally, the first driving device 12 and the mounting position 111 are arranged at a distance in the second direction Y, and the detection element 13 is located between the first driving device 12 and the mounting position 111 in the second direction Y.
[0054] It is understood that the detection element 13 can be directly connected to the first driving device 12; the detection element 13 can also be indirectly connected to the first driving device 12, for example, the detection element 13 is connected to the first driving device 12 through other driving devices.
[0055] The first driving device 12 is used to drive the detection component 13 to move along the first direction X. It is necessary to ensure that the detection component 13 moves from one side of the flexible circuit board to the other side of the flexible circuit board in the first direction X so as to detect the entire bending position of the flexible circuit board, so as to detect more comprehensively and avoid deviation in the detection results.
[0056] The beneficial effects of the flexible circuit board bending position detection fixture 10 provided in this application embodiment are as follows: After the display component is positioned and installed on the mounting platform 11, the detection component 13 is driven to move along the first direction X by the first driving device 12. During the movement, the detection component 13 detects the flexible circuit board of the display component. Compared with human eye detection, the detection position is determined and human subjectivity is avoided, reducing or even eliminating the deviation of the detection results; moreover, it eliminates the need to set alignment lines on the glass plate or flexible circuit board, reducing the production steps of the display component and improving the production efficiency of the display component.
[0057] In some embodiments, the detection element 13 is a detection block.
[0058] Taking the first display component 20 as an example, the structure of the first display component 20 is as follows: Figure 1 and Figure 2 As shown, the first glass plate 21 is connected to the first display module 23 through the first optical adhesive 22, and the first flexible circuit board 25 is connected to the first rigid circuit board 24 after being bent. The maximum distance between the bending position of the first flexible circuit board 25 and the edge of the first glass plate 21 is W1. When the first adhesive frame 26 is installed on the first glass plate 21, it is to prevent the first adhesive frame 26 from damaging the circuit on the first flexible circuit board 25.
[0059] Please refer to the following at the same time Figure 5 , Figure 6 and Figure 9During testing, driven by the first driving device 12, the detection block moves along the first direction X from one side of the first flexible circuit board 25 to the other side. If the detection block does not contact the bending position of the first flexible circuit board 25, it indicates that the bending position of the first flexible circuit board 25 is acceptable and will not affect the installation of the first frame 26; if the detection block contacts the bending position of the first flexible circuit board 25, it indicates that the bending position of the first flexible circuit board 25 is unacceptable and will affect the installation of the first frame 26. Of course, the detection block can also be used to detect whether the bending position of the second flexible circuit board 35 of the second display assembly 30 is acceptable.
[0060] The detection component 13 provided in this embodiment is a detection block. The detection block performs physical detection on the flexible circuit board, which is low-cost while ensuring the accuracy of the detection results.
[0061] In other embodiments, the detection element 13 may also be a detection plate.
[0062] Please refer to the following at the same time Figure 7 and Figure 8 In some embodiments, the detection element 13 is a detection block, which has a groove 131 for sliding engagement with the edge of the first glass plate 21. The groove 131 includes a first groove wall 1311 parallel to the first glass plate 21 and a second groove wall 1312 perpendicular to the first glass plate 21. The dimension of the first groove wall 1311 in the second direction Y is a set dimension.
[0063] The shape of the detection block is not limited in this application, as long as the groove 131 can be formed on it; for example, the detection block can be a rectangular block, a triangular block, etc.
[0064] The set dimension is equal to the limit distance W1 between the bending position of the first flexible circuit board 25 and the edge of the first glass plate 21.
[0065] The first groove wall 1311 is parallel to the first glass plate 21, and the second groove wall 1312 is perpendicular to the first glass plate 21. This can be understood as the first groove wall 1311 being perpendicular to the second groove wall 1312.
[0066] During testing, the first groove wall 1311 is positioned above the first glass plate 21. The first groove wall 1311 can be arranged in close contact with the upper surface of the first glass plate 21 or spaced apart from the upper surface of the first glass plate 21. The second groove wall 1312 is close to the side (i.e., the vertical surface) of the first glass plate 21 to ensure that the dimension of the first groove wall 1311 in the second direction Y is equal to the limit distance W1.
[0067] By setting a groove 131 on the detection block, the detection block is able to slide and detect by gripping the edge of the first glass plate 21. This detection block is particularly suitable for detecting the first flexible circuit board 25 of the first display assembly 20.
[0068] In other embodiments, such as Figure 6 As shown, the slide groove 131 may not be provided on the detection block. The lower surface of the detection block may be arranged in close contact with the upper surface of the first glass plate 21, or it may be arranged at a distance from the upper surface of the first glass plate 21.
[0069] In some embodiments, the detection block is a soft detection block.
[0070] The detection block is made of a soft material, which can be rubber, silicone, plastic, etc.
[0071] By designing the detection block as a soft detection block, when the detection block comes into contact with the flexible circuit board during testing, the detection block can play a certain buffering role, so that the force exerted by the detection block on the flexible circuit board is smaller, thereby reducing the damage to the flexible circuit board.
[0072] Please refer to Figure 7 In some embodiments, the detection element 13 is a detection block, and the first driving device 12 includes a drive motor 122, which integrates a torque sensor.
[0073] During testing, when the detection block contacts the flexible circuit board, the torque suddenly increases. The torque sensor transmits the signal of increased torque to the controller, which then controls the drive motor 122 to stop, thereby reducing damage to the flexible circuit board.
[0074] Optionally, the first drive device 12 further includes a lead screw and nut mechanism 121, which includes a lead screw extending along the first direction X and a slider threadedly connected to the lead screw. The lead screw is connected to the output shaft of the drive motor 122, and the detection element 13 is directly or indirectly connected to the slider. The drive motor 122 drives the slider to move in the first direction X through the lead screw, so as to realize the movement of the detection element 13 in the first direction X.
[0075] In some embodiments, the detection element 13 is a light sensor.
[0076] It is understandable that light sensors can be laser sensors, infrared sensors, etc.
[0077] Taking the second display component 30 as an example, the structure of the second display component 30 is as follows: Figure 3 and Figure 4As shown, the second glass plate 31 is connected to the second display module 33 through the second optical adhesive 32, and the second flexible circuit board 35 is connected to the second rigid circuit board 34 after being bent; the maximum distance between the bending position of the second flexible circuit board 35 and the edge of the second glass plate 31 is W2, so that when the second adhesive frame 36 is installed on the decorative part 37, the second adhesive frame 36 is prevented from damaging the circuit on the second flexible circuit board 35.
[0078] Please refer to the following at the same time Figures 10 to 12 During testing, driven by the first driving device 12, the light sensor moves along the first direction X from one side of the second flexible circuit board 35 to the other side. During this process, if the light sensor does not detect a bend in the second flexible circuit board 35, it indicates that the bend is within acceptable limits and will not affect the installation of the second frame 36; if the light sensor detects a bend, it indicates that the bend is not within acceptable limits and will affect the installation of the second frame 36. Of course, the light sensor can also be used to detect whether the bend of the first flexible circuit board 25 of the first display assembly 20 is within acceptable limits.
[0079] The distance between the light from the light sensor and the edge of the second glass plate 31 is equal to the limit distance W2 between the bending position of the second flexible circuit board 35 and the edge of the second glass plate 31.
[0080] The detection component 13 provided in this embodiment is a light sensor. During the detection process of the flexible circuit board, the light sensor will not make physical contact with the flexible circuit board, and therefore will not cause damage to the flexible circuit board.
[0081] In some embodiments, the distance that the detection element 13 moves along the first direction X is 1.5 to 2 times the width of the flexible circuit board of the display component.
[0082] When the display component is the first display component 20, please refer to... Figure 9 The detection block moves a distance of 1.5-2 times the width of the first flexible circuit board 25 along the first direction X to ensure that the detection block can fully detect the first flexible circuit board 25 without moving too far. For example, the distance the detection block moves along the first direction X can be 1.5 times, 1.7 times, or 2 times the width of the first flexible circuit board 25. Of course, the distance the detection block moves along the first direction X can be 1-1.5 times the width of the first flexible circuit board 25, or it can be more than 2 times the width of the first flexible circuit board 25.
[0083] When the display component is the second display component 30, please refer to... Figure 11The distance the light sensor moves along the first direction X is 1.5-2 times the width of the second flexible circuit board 35. This ensures that the light sensor can fully detect the second flexible circuit board 35 without moving too far. For example, the distance the light sensor moves along the first direction X can be 1.5 times, 1.7 times, or 2 times the width of the second flexible circuit board 35. Of course, the distance the light sensor moves along the first direction X can be 1-1.5 times the width of the second flexible circuit board 35, or it can be more than 2 times the width of the second flexible circuit board 35.
[0084] Please refer to Figure 10 In some embodiments, the flexible circuit board bending position detection fixture 10 further includes a second driving device 14 disposed on the first driving device 12, the second driving device 14 being used to drive the detection element 13 to move along the second direction Y.
[0085] Optionally, the second drive device 14 includes a fixed base 142, a sliding base 141, and an adjusting handle 143. The fixed base 142 is fixed to the lead screw and nut mechanism 121. The sliding base 141 is slidably mounted on the fixed base 142 along the second direction Y. The adjusting handle 143 is threaded to the fixed base 142 and rotatably mounted on the sliding base 141. Rotating the adjusting handle 143 drives the sliding base 141 to move along the second direction Y on the fixed base 142. The detection element 13 is directly or indirectly mounted on the sliding base 141. Alternatively, the second drive device 14 can also be a telescopic cylinder or an electric push rod.
[0086] By providing a second driving device 14 on the first driving device 12, the detection element 13 can move simultaneously in the first direction X and the second direction Y, so that the flexible circuit board bending position detection fixture 10 can be adapted to display components of different lengths and widths.
[0087] In other embodiments, please refer to Figure 7 The flexible circuit board bending position detection fixture 10 does not include the second drive device 14, and the detection element 13 is directly set on the first drive device 12.
[0088] Please refer to Figure 6 In some embodiments, in addition to the first driving device 12 and the second driving device 14, the flexible circuit board bending position detection fixture 10 further includes a third driving device 15 disposed on the second driving device 14. The third driving device 15 is used to drive the detection element 13 to move along a third direction Z, which is perpendicular to the first direction X and the second direction Y.
[0089] Optionally, the third drive device 15 can be a telescopic cylinder or an electric push rod; when the third drive device 15 is a telescopic cylinder, the third drive device 15 can be a pneumatic cylinder or a hydraulic cylinder.
[0090] By setting a second driving device 14 on the first driving device 12 and a third driving device 15 on the second driving device 14, the detection element 13 can move simultaneously in the first direction X, the second direction Y and the third direction Y, so that the flexible circuit board bending position detection fixture 10 can be adapted to display components of different lengths, widths and thicknesses.
[0091] In other embodiments, the second driving device 14 may be omitted, and the third driving device 15 may be directly mounted on the first driving device 12.
[0092] Please refer to Figure 5 and Figure 6 In some embodiments, the flexible circuit board bending position detection fixture 10 also includes a vacuum adsorption device disposed in the mounting platform 11, the mounting position 111 is provided with an adsorption hole 113; the mounting position 111 is provided with a positioning block 112 for positioning the display component.
[0093] Optionally, multiple adsorption holes 113 are provided, and the multiple adsorption holes 113 are connected to the vacuum adsorption device through pipelines.
[0094] Optionally, multiple positioning blocks 112 are provided, with at least one positioning block 112 positioning the display component in the first direction X and at least one positioning block 112 positioning the display component in the second direction Y. The mounting platform 11 is provided with multiple fixing holes 114 for fixing the positioning blocks 112, and the positioning blocks 112 can select the appropriate fixing hole 114 according to their installation position.
[0095] After the display component is placed on the mounting position 111, move the display component horizontally to position it using the positioning block 112. Then, activate the vacuum adsorption device to use negative pressure to adhere and fix the display component to the mounting position 111. After the display component is tested, simply turn off the vacuum adsorption device to remove the display component; the operation is quite simple.
[0096] In other embodiments, instead of a vacuum adsorption device, a pressure plate and bolts can be used. The pressure plate has bolt holes, and the mounting platform 11 has threaded holes. After the positioning block 112 positions the display component, the bolts pass through the bolt holes and are screwed into the threaded holes to fix the display component to the mounting position 111 via the pressure plate. A flexible pad can be provided on the side of the pressure plate facing the display component to prevent damage to the display component.
[0097] In other embodiments, the positioning block 112 may be omitted, and instead, a mounting groove may be provided on the mounting platform 11, forming a mounting position 111. The sidewalls of the mounting groove are used to position the display component. Adsorption holes 113 may be provided on the bottom wall of the mounting groove.
