Description

Technical Field

[0001] This utility model relates to the field of display device testing technology, and specifically to a product calibration mechanism for display screen testing. Background Technology

[0002] In the display industry, the production of each display involves many manufacturing processes, among which testing is essential. For displays with pre-attached FPCs, the FPC end needs to be extended and positioned before testing. The common method in existing technology is to use a connector flip cover, where the FPC end is manually inserted into the slot of the connector flip cover, and the flip cover is pressed down to the locked position. Mechanical pressure is used to fix the ribbon cable and ensure tight contact of the terminals. However, this method is prone to deviations due to manual operation and results in low testing efficiency. Utility Model Content

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] refer to Figures 1 to 7 , Figure 1 A perspective view of a product calibration mechanism 1 for detecting a display screen 5 provided in an embodiment of the present invention is shown; Figure 2 A perspective view of the calibration platform 2 in a product calibration mechanism 1 for testing a display screen 5 provided in an embodiment of the present invention is shown; Figure 3 This illustration shows a partial structural diagram of a product calibration mechanism 1 for detecting a display screen 5, provided by an embodiment of the present invention.

Figure 2 ; Figure 5 This illustration shows a partial structural diagram of a product calibration mechanism 1 for detecting a display screen 5, provided by an embodiment of the present invention. Figure 3 ; Figure 6 A perspective view of a transfer component 34 in a product calibration mechanism 1 for detecting a display screen 5, provided by an embodiment of the present invention, is shown. Figure 7 This illustration shows a perspective view of a precision alignment device 4 in a product calibration mechanism 1 for detecting a display screen 5, provided by an embodiment of the present invention.

[0030] like Figures 1 to 7 As shown, Figure 1 This is a perspective view of the product calibration mechanism 1 in actual use. Two product calibration mechanisms 1 are symmetrically arranged, meaning two transfer platforms 33 run on the same second linear slide 32, and materials are alternately transported by a robotic arm assembly 6 near the center, improving equipment utilization. Specifically, the technical solution provided in this application is a product calibration mechanism 1 for detecting a display screen 5. The display screen 5 includes a screen end 50 and an FPC end 51. The FPC end 51 is located on the screen end 50 along a first direction (…). Figure 2 (as shown in the X direction) on one side, and along the second direction ( Figure 2 (As shown in the Y direction) The product calibration mechanism 1 includes the following interval settings:

[0031] The calibration platform 2 includes a platform base plate 20, a screen fixing component 21, and an FPC fixing component 22. The screen fixing component 21 and the FPC fixing component 22 are respectively located at the top of the platform base plate 20 at both ends along the first direction.

[0032] The screen fixing assembly 21 includes an adsorption plate 210, which extends along a first direction and has a first adsorption component inside for supporting and adsorbing the screen end 50.

[0033] The FPC fixing assembly 22 includes a drag block 220, an θ-axis alignment assembly, an X-axis alignment assembly, and a Y-axis alignment assembly. The drag block 220 extends along a first direction and is spaced apart along a second direction. It has a second adsorption assembly inside for supporting and adsorbing the FPC end 51.

[0034] The θ-axis alignment component, X-axis alignment component, and Y-axis alignment component are aligned along a third direction ( Figure 2 (As shown in the Z direction) are sequentially arranged between the drag block 220 and the platform base plate 20, for use in the fourth direction ( Figure 2 The drive block 220 is adjusted in the first and second directions (as shown in the θ direction) and drives the FPC end 51 to move so that the FPC end 51 extends along the first direction, the first direction, the second direction and the third direction are perpendicular to each other, and the fourth direction surrounds the third direction.

[0035] This application provides a product calibration mechanism 1 for testing a display screen 5. By setting up an θ-axis alignment component, an X-axis alignment component, and a Y-axis alignment component, it achieves precise adjustment in the third direction, the first direction, and the rotation direction. This allows for precise adjustment of the position of the FPC end 51, ensuring its alignment accuracy with the screen end 50. Furthermore, the fixing and adjustment processes of the screen end 50 and the FPC end 51 are independent, avoiding mutual interference and improving calibration efficiency. The adsorption-type fixing method can fix the surfaces of the screen end 50 and the FPC end 51 without damage, and the automated design of the alignment components reduces manual intervention and improves the automation level of calibration.

[0036] In some embodiments, reference Figures 1 to 7 The Y-axis alignment assembly includes a first linear module 227 and a first servo motor 228. The first linear module 227 extends along a second direction and includes a first slide plate. The first servo motor 228 is located at the bottom of the platform base plate 20 and is used to drive the first slide plate to move along the second direction. The X-axis alignment assembly includes an X-axis base plate 224, a second linear module 225, and a second servo motor 226. The bottom of the X-axis base plate 224 is connected to the first slide plate, and the top is connected to the second linear module 225. The second linear module 225 extends along a first direction and includes a second slide plate. The second servo motor 226 is located on one side of the second linear module 225 along the second direction and is used to drive the second slide plate to move along the first direction. The θ-axis alignment assembly includes an θ-axis base plate 222 and a rotary reducer 223. The bottom of the θ-axis base plate 222 is connected to the second slide plate, and the top is connected to the rotary reducer 223. A drag block 220 is located on top of the rotary reducer 223.

[0037] For example, through the coordinated operation of the first linear module 227, the second linear module 225, and the rotary reducer 223, the position and angle of the FPC end 51 can be precisely adjusted in three directions (the third direction, the first direction, and the rotation direction) to ensure its accurate alignment with the screen end 50. The linkage design of the multi-axis alignment components makes the adjustment process smoother, reduces the accumulation of errors caused by adjusting each direction individually, and improves the overall accuracy of the calibration.

[0038] In some embodiments, reference Figures 1 to 7 The first adsorption assembly includes multiple suction cups 211 and a first solenoid valve assembly 212. The multiple suction cups 211 are spaced apart along a first direction and a second direction and are located at one end of the adsorption plate 210 near the drag block 220. The bottom of the adsorption plate 210 has upright plates 213 at both ends along the second direction and at the end away from the drag block 220 along the first direction. The bottom of the upright plates 213 is connected to the platform base plate 20 and forms a placement space. The first solenoid valve assembly 212 is located within the placement space and is correspondingly connected to the bottom of the multiple suction cups 211. The second adsorption assembly includes multiple suction nozzles 221 and a second solenoid valve assembly. The multiple suction nozzles 221 are spaced apart along the first direction and a second direction within the drag block 220, and the bottom of each suction nozzle 221 is correspondingly connected to the second solenoid valve assembly.

[0039] For example, the first and second adsorption components employ multiple suction cups 211 and suction nozzles 221 spaced apart along a first direction and a third direction, respectively. This multi-point adsorption design increases the number of adsorption points, improves the overall adsorption force, and more firmly fixes the display screen 5, preventing displacement during alignment or calibration. The solenoid valve assembly can quickly switch between adsorption and release states as needed, ensuring the accuracy and timeliness of the adsorption process. For example, when temporary release of the FPC end 51 is required for adjustment during calibration, the solenoid valve assembly can respond quickly, avoiding operational difficulties caused by excessive adsorption force. Specifically, as... Figure 2 and Figure 3 As shown, multiple suction cups 211 form a small quadrilateral in the center and a large quadrilateral on the outside, thereby adapting to displays 5 of different sizes.

[0040] In some embodiments, reference Figures 1 to 7The calibration platform 2 also includes a first pull rod 229, a second pull rod 230, and multiple rubber strips 231. The first pull rod 229 and the second pull rod 230 are respectively located at both ends of the adsorption plate 210 along the second direction, and both extend along the first direction towards the FPC fixing assembly 22. The first pull rod 229 and the second pull rod 230 are each provided with multiple annular grooves spaced apart along the first direction. The multiple rubber strips 231 are spaced apart along the first direction and located between the adsorption plate 210 and the drag block 220. Each rubber strip 231 is arranged to surround the first pull rod 229 and the second pull rod 230 in sequence, and is configured to cooperate with two annular grooves corresponding to the first pull rod 229 along the second direction, for supporting the FPC end 51 through the top of the multiple rubber strips 231.

[0041] For example, the rubber strip 231 has good elasticity, which can provide cushioning for the FPC end 51, reduce the risk of damage caused by vibration or impact during alignment or correction, and provide effective auxiliary support for the tail end of the FPC end 51, whether it is too long or too short.

[0042] In some embodiments, reference Figures 1 to 7 The FPC support assembly also includes multiple additional drag blocks 232, which are located on the side of the drag block 220 away from the second servo motor 226 along the second direction. The bottom of the additional drag block 232 along the second direction and the bottom of the drag block 220 facing the additional drag block 232 are both provided with corresponding insertion grooves 234. The other side of the additional drag block 232 along the second direction is provided with an insertion protrusion 233 that matches the size of the insertion groove 234, for inserting and fixing the additional drag block 232 and the drag block 220 through the insertion protrusion 233 and the insertion groove 234.

[0043] For example, the additional drag block 232 is quickly connected to the insertion groove 234 of the drag block 220 via the insertion protrusion 233, and further connected and fixed at the insertion point by bolts. The additional drag block 232 can be easily connected to the main drag block 220 via the insertion structure, allowing users to flexibly increase or decrease the number of additional drag blocks 232 according to the length or quantity requirements of the FPC, thereby expanding the length and load-bearing capacity of the load-bearing component, avoiding over-investment or insufficient functionality due to fixed equipment specifications, and reducing the purchase and use costs of the equipment. Specifically, as... Figure 2 and Figure 3 As shown, in this embodiment, the display screen 5 has two FPCs, both of which are supported and fixed by the drag block 220. In actual production, the number of FPCs can be multiple, such as four FPC ends 51. The two outermost FPC ends 51 are fixed by the drag block 220, and the two middle FPC ends 51 are supported by the additional drag block 232.

[0044] In some embodiments, reference Figures 1 to 7The product calibration mechanism 1 also includes a material conveying mechanism, which comprises a first linear slide 31, a second linear slide 32, a transfer platform 33, and a transfer assembly 34. The first linear slide 31 and the second linear slide 32 are arranged parallel to each other along a second direction and each includes a first slider and a second slider. The calibration platform 2 is located on top of the first slider and is used to drive the calibration platform 2 to move along the first direction via the first linear slide 31. The transfer platform 33 is located on top of the second slider and is used to drive the transfer platform 33 to move along the first direction via the second linear slide 32. The transfer assembly 34 is located at the same end of the first linear slide 31 and the second linear slide 32 along the first direction and is used to transfer the display screen 5 located on the transfer platform 33 to the calibration platform 2.

[0045] In some embodiments, reference Figures 1 to 7 The transfer component 34 includes a support frame 340, a third linear slide 341, a triangular upright plate 342, and a connecting frame. The support frame 340 is sequentially mounted on both sides of the first linear slide 31 and the second linear slide 32 along a second direction. The third linear slide 341 is located at the top of the support frame 340 on the side away from the calibration platform 2 along a first direction and extends along the second direction, including a third slider. The triangular upright plate 342 is located on one side of the third slider along the first direction, and its bottom is connected to the connecting frame. The bottom of the connecting frame is provided with multiple suction cups 211 for adsorbing and transferring products. A third solenoid valve group 351 is provided inside the triangular upright plate 342. The third solenoid valve group 351 is correspondingly connected to the multiple suction cups 211 for controlling the adsorption or release of the multiple suction cups 211.

[0046] For example, the transfer component 34 is driven by the third linear slide 341, enabling high-precision linear motion. The triangular support plate 342 provides a stable support structure for the transfer component 34, and the third solenoid valve group 351 is connected to multiple suction cups 211, enabling precise control of the suction and release of the suction cups 211. The solenoid valve group can quickly switch between suction and release states as needed, ensuring the accuracy and timeliness of the transfer process.

[0047] In some embodiments, reference Figures 1 to 7The connecting frame includes a first connecting rod 343, a second connecting rod 344, multiple support rods 345, and a fixing plate 346. The first connecting rod 343 and the second connecting rod 344 are arranged parallel to each other along a first direction. The multiple support rods 345 are spaced apart along the first direction, and each support rod 345 extends along a second direction, with its two ends connected to the first connecting rod 343 and the second connecting rod 344, respectively. Each support rod 345 has a mounting through hole 347 extending along a third direction, and multiple suction cups 211 are spaced apart along the second direction within the mounting through hole 347 to form an adsorption surface at the bottom of the connecting frame. The top of the fixing plate 346 is connected to a triangular upright plate 342, and its two ends along the second direction are connected to the first connecting rod 343 and the second connecting rod 344, respectively.

[0048] For example, each support rod 345 is provided with a mounting through hole 347 extending in a third direction. The suction cup 211 can be installed in these through holes, and its position can be adjusted in the third direction as needed to accommodate displays 5 of different sizes and shapes. The suction cup 211 can not only be adjusted in the third direction, but also in a second direction through the spacing of the support rods 345, further improving the flexibility of the suction cup 211 layout.

[0049] In some embodiments, reference Figures 1 to 7 The transfer assembly 34 also includes a code reader assembly, which is located on the other side of the support frame 340 along the first direction. The code reader assembly includes a fourth linear slide 348, a connecting sheet metal 349, and a code reader 350. The fourth linear slide 348 extends along the second direction and includes a fourth slider. The code reader 350 is located above the second linear slide 32 and is used to detect the display screen 5 on the top of the transfer platform 33. The two ends of the connecting sheet metal 349 are respectively connected to the fourth slider and the code reader 350, and are used to adjust the position of the code reader 350 in the second direction via the fourth linear slide 348.

[0050] For example, the barcode reader 350 can directly detect the identification information (such as QR code, barcode, etc.) of the display screen 5 on the transfer platform 33, obtain the production information of the display screen 5 in real time, and complete the barcode reading operation simultaneously during the transfer process, reducing additional detection steps and improving production efficiency.

[0051] In some embodiments, reference Figures 1 to 7The product calibration mechanism 1 also includes a precision alignment device 4, which includes a frame 40, a screen precision alignment assembly, and an FPC precision alignment assembly. The frame 40 is mounted at both ends of the first linear slide 31 along the second direction and is located on one side of the support frame 340 along the second direction. The screen precision alignment assembly is located on the side of the frame 40 away from the support frame 340 along the first direction, and the FPC precision alignment assembly is located on the other side of the frame 40 along the first direction. The screen precision alignment assembly includes a fifth linear slide 41, a screen alignment camera 42, and a camera mounting plate 43. The fifth linear slide 41 extends along the second direction, and the screen alignment cameras 42 are spaced apart along the second direction and are slidably connected to the fifth linear slide 41 through the camera mounting plate 43. The FPC alignment assembly includes a sixth linear slide 44, an FPC alignment camera 45, and a camera mounting plate 46. The sixth linear slide 44 extends along a second direction, and the FPC alignment cameras 45 are spaced apart along the second direction and are slidably connected to the sixth linear slide 44 via the camera mounting plate 46.

[0052] For example, the screen alignment camera 42 and the FPC alignment camera 45 can be moved and adjusted with high precision in the second direction via the fifth linear slide 41 and the sixth linear slide 44, ensuring that the cameras can be accurately aligned with the screen end 50 and the FPC end 51, thus improving alignment accuracy. The precision alignment device 4 can adapt to displays 5 of different sizes and shapes, and meet diverse production needs by adjusting the position of the cameras and the alignment algorithm.
