Description

Technical Field

[0001] This utility model relates to the field of display device manufacturing technology, and in particular to a display panel testing device. Background Technology

[0002] After assembly, the display panel needs to undergo a lamp-light test. The display panel will display different images based on the test signals provided by the display panel testing device to determine if there are any defects in the display panel, thus avoiding problems such as difficult disassembly and easy damage to components after full assembly. During the lamp-light test, the probes of the display panel testing device will contact the electrodes at preset positions on the display panel to achieve electrical connection between the testing probes and the display panel, allowing the current provided by the display panel testing device to be conducted to the display panel through the probes.

[0003] Currently, manufacturers typically produce multiple display panels simultaneously on a single substrate to ensure production efficiency. Therefore, existing display panel inspection devices need to inspect multiple display panels on the substrate, referring to...

[0033] The advantages and features of this invention, as well as methods of implementing them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, this invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of this invention and to enable those skilled in the art to fully understand its scope, which is defined only by the scope of the claims. The same reference numerals denote the same constituent elements throughout the specification.

[0034] The present invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figures 2 to 5 As shown, the display panel detection device of this utility model embodiment includes a fixing frame 1, a detection component 2, and a driving component 3. The detection component 2 includes a mounting plate 21, a detection component 221, and at least two guide rails 23. The mounting plate 21 has a first side 211 adjacent to the display panel 101 along a first direction (the first direction is the Z direction shown in the figure, i.e., the vertical direction). The guide rails 23 are disposed on the first side 211, and at least a portion of the length of the guide rails 23 extends along a second direction (the second direction is the X direction shown in the figure), and at least a portion of the length of the guide rails 23 extends along a third direction (the third direction is the Y direction shown in the figure). Each guide rail 221... Multiple detectors 221 are provided on each of the three components. The detectors 221 can be slidably mounted on the guide rail 23 and selectively fixed. Each detector 221 corresponds to a test area of ​​the display panel 101. The detector 221 is provided with a probe 2211. The driving component 3 is mounted on the fixing frame 1 and is connected to the mounting plate 21. The driving component 3 drives the mounting plate 21 to move along the first direction, so that the probes 2211 of the multiple detectors 221 can respectively contact the electrode parts of the multiple test areas on the display panel 101. The first direction, the second direction and the third direction are perpendicular to each other.

[0036] It is understandable that by adjusting the movable setting of the probe 221, the position of the probe 221 can be adjusted to correspond to different sizes of display panels 101, thereby satisfying the detection of display panels 101 of different sizes, improving the compatibility of the probe assembly 2, and improving the alignment accuracy between the probe 2211 on each probe 221 and the electrode part on the display panel 101.

[0037] Furthermore, such as Figure 2 and Figure 3 As shown, the guide rail 23 includes a first guide block 231 and a second guide block 232 spaced apart. Each of the first guide block 231 and the second guide block 232 has a groove 233 on one side adjacent to each other. The length of the groove 233 extends along the length direction of the guide rail 23, and the groove 233 at least penetrates one side of the guide rail 23 along its own length direction to form a mounting opening. The two grooves 233 spaced apart form a receiving space 234. The probe 221 is slidably disposed within the receiving space 234. The guide rail 23 has a second side surface 235 adjacent to the display panel 101 along a first direction. The probe 2211 of the probe 221 at least partially protrudes from the second side surface 235. The probe 221 can be inserted into the receiving space 234 through the mounting opening, and the probe 221 can be moved and adjusted according to the position of the electrode portion of the area to be tested on the display panel 101, thereby improving the alignment accuracy between the probe 221 and the display panel 101.

[0038] Of course, by using the first guide block 231 and the second guide block 232 spaced apart, a wire passage space communicating with the receiving space 234 can be formed between the first guide block 231 and the second guide block 232, so that the connecting wire of the probe 221 can pass through the wire passage space and connect with the circuit board located on the mounting plate 21, thereby improving the ease of movement adjustment and connection of the probe 221. In addition, taking the guide rail 23 extending along the second direction as an example and naming it the first guide rail 236, the first guide block 231 and the second guide block 232 in the first guide rail 236 are arranged at intervals along the third direction. The groove walls of the sliding grooves 233 of the first guide block 231 and the second guide block 232 can restrict the probe 221 along the first direction and the third direction, effectively improving the smoothness of movement and installation stability of the probe 221.

[0039] Optionally, the first guide block 231 has a first strip hole 2311 on the side away from the second guide block 232. The length of the first strip hole 2311 extends along the length direction of the first guide block 231. The probe 221 has a first threaded hole 2212. The first bolt passes through the first strip hole 2311 and is screwed into the first threaded hole 2212, thus fixing the probe 221 onto the guide rail 23. By providing the first strip hole 2311, after the probe 221 is adjusted along the second direction, the bolt can be aligned with the first threaded hole 2212 of the probe 221 and passed through the first strip hole 2311 to be screwed into the first threaded hole 2212, allowing the head of the first bolt to abut against the first guide block 231, thereby fixing the probe 221 after movement and adjustment.

[0040] Furthermore, such as Figure 4 and Figure 5 As shown, the detector 221 includes a mounting base 2213 and a detector block 2214. The mounting base 2213 is slidably disposed in the receiving space 234, and the detector block 2214 is detachably connected to the mounting base 2213. Multiple probes 2211 are disposed on the detector block 2214. During use, the probes 2211 inevitably experience contact wear. The detachable connection between the detector block 2214 and the mounting base 2213 facilitates the removal and replacement of the detector block 2214 for maintenance, reducing the maintenance cost of the detector 221.

[0041] Specifically, the detector 221 also includes an elastic buckle, which includes a locking pin 2215 and an elastic element 2216. The mounting base 2213 is provided with a mounting groove 22131 along the side of the display panel 101 in the first direction. The detector block 2214 is inserted into the mounting groove 22131. The mounting base 2213 is provided with a mounting hole communicating with the mounting groove 22131 along the side perpendicular to the first direction. The locking pin 2215 is slidably connected to the mounting hole. The detector block 2214 is provided with a snap-fit ​​hole 22141 corresponding to the mounting hole position. The locking pin 2215 is connected to the mounting base 2213 through the elastic element 2216. The elastic element 2216 has a tendency to drive the locking pin 2215 to always be inserted into the snap-fit ​​hole 22141. During disassembly, simply pull the locking pin 2215 to move it away from the probe block 2214, allowing it to disengage from the locking hole 22141 and remove the probe block 2214. During installation, similarly pull the locking pin 2215 to prevent it from obstructing the installation of the probe block 2214. After inserting the probe block 2214 into the mounting hole, release the locking pin 2215, allowing it to engage with the locking hole 22141 under the action of the elastic element 2216. This facilitates easy disassembly and assembly.

[0042] In this embodiment, the elastic element 2216 is a tension spring, and the end of the locking pin 2215 away from the detector block 2214 is provided with a stop portion. The tension spring is connected to the stop portion and the mounting base 2213. Of course, to facilitate the installation of the detector block 2214, the end of the locking pin 2215 adjacent to the detector block 2214 is provided with an inclined surface 22151. The inclined surface 22151 slopes downwards from the end adjacent to the detector block 2214 towards the end away from the detector block 2214. Under the tension of the tension spring in its natural state, the inclined surface 22151 is partially located within the mounting hole. During installation, the detector block 2214 is directly inserted into the mounting groove 22131 along the opening of the mounting groove 22131. 214 can push the locking pin 2215 along the inclined surface 22151, so that the locking pin 2215 can overcome the tension spring and move away from the probe block 2214, so that the probe block 2214 can be inserted into the mounting groove 22131. When the locking pin 2215 is opposite to the locking hole 22141, the locking pin 2215 disengages from the abutting push of the probe block 2214, and under the action of the tension spring, the locking pin 2215 is inserted into the locking hole 22141, effectively improving the installation convenience of the probe block 2214.

[0043] Preferably, the mounting base 2213 includes a main body and a mounting part. The main body is slidably disposed within the receiving space 234. The mounting part protrudes from the side of the main body facing the display panel 101, and a portion of the mounting part is exposed on the second side 235. An elastic buckle is disposed on the mounting part and located below the second side 235, so that the mounting base 2213 can achieve quick replacement of the probe block 2214 even when mounted on the guide rail 23. In addition, a mounting groove 22131 is disposed on the mounting part, and a wire through hole 2217 communicating with the mounting groove 22131 is also provided on the side of the main body away from the mounting part, so that the connecting wire of the probe block 2214 can pass through and connect to the circuit board on the mounting plate 21.

[0044] Of course, the width of the area to be measured may vary, therefore, the number or spacing of the probes 2211 on the corresponding probe block 2214 may also vary. Thus, the probe element 221 includes multiple probe blocks 2214, and at least some of the probe blocks 2214 have different numbers of probes 2211, so as to facilitate the replacement of different probe blocks 2214. In addition, multiple placement slots can be provided on the side of the mounting plate 21 away from the display panel 101 to store the replaceable probe blocks 2214, thereby facilitating the replacement of the probe blocks 2214.

[0045] In some embodiments, such as Figure 2 and Figure 3As shown, at least a portion of the guide rail 23 is provided with multiple detection units 22, each detection unit 22 corresponding to a display panel 101 on the substrate 100. The detection unit 22 includes multiple detector elements 221, and the number of detector elements 221 in at least a portion of the detection units 22 is different. Taking the guide rail 23 extending along the second direction as the first guide rail 236 as an example, when multiple display panels 101 are spaced apart along the second direction on the substrate 100, and the dimensions of some display panels 101 are different along the second direction, it is necessary to set multiple sets of detection units 22 on the first guide rail 236 to correspond to multiple display panels 101 arranged along the second direction, and adjust the number and position of detector elements 221 according to the area to be tested of the display panel 101, so that the display panel detection device can simultaneously detect multiple display panels 101 arranged along the second direction on the substrate 100.

[0046] Similarly, taking the guide rail 23 extending along the third direction as an example, the second guide rail 237 is provided with multiple detection units 22, and at least some of the detection units 22 have different numbers of detection elements 221. That is, multiple display panels 101 are arranged at intervals along the third direction on the substrate 100, and some of the display panels 101 have different dimensions along the third direction. Therefore, by setting multiple sets of detection units 22 on the second guide rail 237 to correspond to multiple display panels 101 arranged along the third direction, and adjusting the number and position of detection elements 221 according to the area to be tested of the display panel 101, the display panel detection device can simultaneously detect multiple display panels 101 arranged along the third direction on the substrate 100.

[0047] By setting multiple detection units 22 on the first guide rail 236 and the second guide rail 237, and adaptively adjusting the position of each probe 2211 unit corresponding to a display panel 101 on the substrate 100, synchronous detection of multiple display panels 101 on the substrate 100 is achieved, effectively improving the detection efficiency of the display panel detection device. Furthermore, each detection unit 22 has multiple probes 221, each probe 221 corresponding to a test area on the display panel 101, enabling synchronous detection of multiple test areas on multiple display panels 101, resulting in high detection efficiency.

[0048] Furthermore, the first side 211 is provided with a plurality of guide rails 23 extending along the second direction. The plurality of guide rails 23 are arranged at intervals along the third direction, which can realize multiple sets of display panel groups arranged along the third direction. Each set of display panel groups has multiple display panels 101 arranged along the second direction for detection.

[0049] Similarly, the first side 211 is provided with a plurality of guide rails 23 extending along a third direction. The plurality of guide rails 23 are arranged at intervals along the second direction, which can realize multiple sets of display panel groups arranged along the second direction. Each set of display panel groups has multiple display panels 101 arranged in the third direction for detection, and can detect multiple display panels 101 arranged along the second direction on the substrate 100.

[0050] Specifically, taking a guide rail 23 extending along the second direction as the first guide rail 236 and a guide rail 23 extending along the third direction as the second guide rail 237 as an example, the first side 211 is provided with multiple first guide rails 236 arranged along the third direction, and each first guide rail 236 is provided with multiple detection units 22, which can satisfy the requirement of multiple display panel groups arranged along the third direction, and each group of display panels 101 corresponds to the detection of multiple display panels 101 arranged along the second direction; similarly, the first side 211 is provided with multiple second guide rails 237 arranged along the second direction, and each second guide rail 237 is provided with multiple detection units 22, which can satisfy the requirement of multiple display panel groups arranged along the second direction, and each group of display panels 101 corresponds to the detection of multiple display panels 101 arranged along the third direction, which has wide versatility.

[0051] Furthermore, such as Figure 2 and Figure 3 As shown, at least some of the guide rails 23 are detachably connected to the mounting plate 21. In other words, depending on the arrangement of the display panels 101 on different substrates 100, the guide rails 23 at the corresponding positions can be assembled, improving the versatility of the display panel testing device to be compatible with the production of various types of display panels 101.

[0052] Optionally, the mounting plate 21 has a second strip-shaped hole 212 extending through it in the first direction. The length of the second strip-shaped hole 212 extends in the third direction. The guide rail 23 has a second threaded hole. The second bolt passes through the second strip-shaped hole 212 and is screwed into the second threaded hole to fix the guide rail 23 to the mounting plate 21. The guide rail 23 at this time is the first guide rail 236 described above. The second strip-shaped hole 212 allows the first guide rail 236 to be adjusted by a certain distance in the third direction, improving the alignment accuracy between the detection unit 22 on the first guide rail 236 and the display panel 101, so as to meet the detection of more types of display panels 101. During adjustment, it is only necessary to loosen the second bolt, move the first guide rail 236 to the designated position in the third direction, and then tighten the second bolt so that the head of the second bolt abuts against the mounting plate 21 to achieve fixation. The adjustment is convenient. It is worth noting that the mounting plate 21 has at least two second strip holes 212 spaced apart along a third direction, and the guide rail 23 has at least two corresponding second threaded holes to ensure the connection stability between the guide rail 23 and the mounting plate 21.

[0053] Similarly, the mounting plate 21 has a third strip-shaped hole 213 extending through it in the first direction. The length of the third strip-shaped hole 213 extends in the second direction. The guide rail 23 has a third threaded hole. The third bolt passes through the third strip-shaped hole 213 and is screwed into the third threaded hole to fix the guide rail 23 to the mounting plate 21. The guide rail 23 at this time is the second guide rail 237 described above. The third strip-shaped hole 213 allows the second guide rail 237 to be adjusted by a certain distance in the second direction, improving the alignment accuracy between the detection unit 22 on the second guide rail 237 and the display panel 101, so as to meet the detection of more types of display panels 101. During adjustment, it is only necessary to loosen the third bolt, move the second guide rail 237 to the designated position in the second direction, and then tighten the third bolt so that the head of the third bolt is pressed against the mounting plate 21 to achieve fixation. The adjustment is convenient. It is worth noting that the mounting plate 21 has at least two third strip holes 213 spaced apart along the second direction, and the guide rail 23 has at least two corresponding third threaded holes to ensure the connection stability between the guide rail 23 and the mounting plate 21.

[0054] Furthermore, in this embodiment, the length of the guide rail 23 extends in one direction. However, in other embodiments, the guide rail 23 can also be an L-shaped guide rail. The L-shaped guide rail includes a first part and a second part that are arranged vertically. The first part extends in a second direction, and the second part extends in a third direction. A plurality of detectors 221 are respectively provided on the first part and the second part.

[0055] In other embodiments, within the same detection unit 22, a first magnet is provided on one side of two adjacent detector elements 221, and a second magnet is provided on the other side, with the first magnet attracting the second magnet. In other words, for the detector elements 221 attached within the detection unit 22, only the first detector element 221 needs to be fixed with bolts, and the other detector elements 221 can be connected by the magnetic attraction of the magnets, improving the convenience of installing the detector elements 221 within the detection unit 22.

[0056] Optionally, on the same guide rail 23, one of the two adjacent detector elements 221 of two adjacent detector units 22 is provided with a third magnet, and the other is provided with a fourth magnet. The third magnet and the fourth magnet repel each other. That is, the principle of mutual repulsion between the third magnet and the fourth magnet is used to prevent the two adjacent detector elements 221 of the two adjacent detector units 22 from getting too close to each other, thereby ensuring the spacing between the two detector units 22. Of course, bolts can also be used to fix the two adjacent detector elements 221 of the two adjacent detector units 22 to the guide rail 23.

[0057] Although embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be made in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.
