Description

Technical Field

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

[0002] P-Aging, or pre-aging process, is a crucial step in the display panel manufacturing process. Its main purpose is to simulate aging conditions in real-world usage environments to prematurely expose potential problems that may arise during subsequent use, thereby ensuring the quality and reliability of the display panel.

[0003] One aspect of the pre-aging process is the power-on test, as referred to... Figure 1 As shown, in the traditional power-on test, the display panel 3' is connected to the connecting plate 1'. The connecting plate 1' is equipped with a connecting probe 2'. The power is applied by contacting the solder pad 4' on the display panel 3' with the connecting probe 2' and continuing for a certain period of time to test the withstand voltage performance and insulation performance of the display panel 3' and to discover potential problems such as insulation breakdown and electromigration.

[0004] The existing technology has the following shortcomings: Display panels 3' come in various specifications. In traditional operations, the number and position of the connection probes 2' on the connection plate 1' are fixed. However, the positions of the pads 4' differ on different specifications of display panels 3'. Therefore, for different specifications of display panels 3', it is necessary to replace the connection plate 1' with the corresponding specification. In actual operation, the connection plate 1' used for power-on testing is heavy equipment, located at a high position on the testing device. Operators need to use tools such as lifts to operate and replace it. Furthermore, the connection plate 1' itself is heavy, resulting in low labor intensity for operators, low replacement efficiency, and safety hazards. Utility Model Content

[0035] 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.

[0036] The present invention will now be described in detail with reference to the accompanying drawings.

[0037] like Figures 3 to 11 As shown, the panel power-on testing device of this utility model embodiment includes a fixed base plate 7, a connecting plate 1, and a connecting module 5. The fixed base plate 7 and the connecting plate 1 are spaced apart, and a panel 2 is placed between the fixed base plate 7 and the connecting plate 1. The connecting plate 1 has a first side 11 and a second side 12. The first side 11 faces the panel 2 and is provided with a plurality of connectors 3. The second side 12 is provided with a controller interface 4. The connecting module 5 is detachably connected to the connectors 3. One end of the connecting module 5 connected to the connector 3 is provided with a plug 511, which is connected to the controller interface 4. The other end of the connecting module 5 is provided with a connection probe 6 electrically connected to the plug 511, which is connected to the solder pad 21 on the panel 2. In actual operation, the fixed base plate 7 and the connecting plate 1 are connected by a driving assembly 8. The driving assembly 8 drives the connecting plate 1 to move relative to the fixed base plate 7 to place the panel 2 and install the connecting module 5.

[0038] In this embodiment, the panel 2 is clamped and fixed by the base plate 7 and the connecting plate 1. Then, the connecting module 5 is installed on the connector 3 so that the connecting probe 6 on the connecting module 5 contacts and connects to the pads 21 on the panel 2. An external control device (not shown) is activated to control the controller interface 4 to perform a power-on test on the panel 2. The detachable connection between the connecting module 5 and the connector 3 allows for the connection of the corresponding specification of the connecting module 5 to the corresponding connector 3 based on the position of the pads 21 on different panels 2. The connecting probe 6 on the corresponding connecting module 5 connects to the corresponding pads 21 on the panel 2, making it suitable for various panel 2 specifications and highly versatile.

[0039] In one embodiment, the connection module 5 includes a connection part 51 and a contact part 52 that are interconnected. A plug 511 is disposed at the end of the connection part 51 away from the contact part 52, and a connection probe 6 is disposed at the end of the contact part 52 away from the connection part 51. Specifically, the connector 3 is provided with a connection slot 31, and the connection plate 1 is provided with a connection through hole 13 that penetrates the connection plate 1. One end of the connection through hole 13 is provided with a connector 3, and the other end of the connection through hole 13 is provided with a controller interface 4. The connection part 51 is inserted into the connection slot 31 and passes through the connection through hole 13, so that the plug 511 is connected to the controller interface 4, so that the external controller can output current to the pad 21 through the connection probe 6 to realize the power-on test of the panel 2.

[0040] In one embodiment, a slot 32 is provided on the inner sidewall of the connecting slot 31, and an elastic locking block 53 is provided on the connecting part 51 to engage with the slot 32. Through the connection between the elastic locking block 53 and the slot 32, and by utilizing the elastic characteristics of the elastic locking block 53, the elastic locking block 53 can have two states: engaging with the slot 32 and disengaging from it. This achieves a detachable connection between the connecting part 51 and the connecting slot 31, which is simple in structure and easy to operate.

[0041] In one embodiment, an operation switch 33 is provided within the slot 32. The operation switch 33 protrudes from the slot 32 and is located on the outer wall of the connecting slot 31. By operating the switch 33, the elastic locking block 53 is pushed out of the slot 32, thereby releasing the connection between the connecting part 51 and the connecting slot 31, thus achieving a detachable connection between the connecting part 51 and the connecting slot 31. This operation is simple and convenient. For example... Figure 6 As shown, the card slot 32 includes a first channel 321 disposed adjacent to the inner side wall of the connecting slot 31 and a second channel 322 disposed adjacent to the outer side wall of the connecting slot 31. The cross-sectional area of ​​the first channel 321 is larger than that of the second channel 322. The operating switch 33 is provided with a first limiting block 331 at one end of the first channel 321. The cross-sectional area of ​​the first limiting block 331 is less than or equal to the cross-sectional area of ​​the first channel 321 and larger than that of the second channel 322, so as to limit the operating switch 33 by the first limiting block 331, preventing the operating switch 33 from coming out of the side of the second channel 322 away from the first channel 321, that is, preventing the operating switch 33 from coming out of the outer side wall of the connecting slot 31, and ensuring that the operating switch 33 is stably inserted into the card slot 32.

[0042] Furthermore, a second limiting block 332 is provided at one end of the operating switch 33 located outside the slot 32. The cross-sectional area of ​​the second limiting block 332 is larger than the cross-sectional area of ​​the second channel 322, so as to limit the operation switch 33 by the second limiting block 332 to prevent the operating switch 33 from coming out of the side of the second channel 322 adjacent to the first channel 321, that is, to prevent the operating switch 33 from coming out of the inner side wall of the connecting slot 31, and further ensure that the operating switch 33 is stably inserted into the slot 32.

[0043] In one embodiment, a groove 54 is provided within the connecting portion 51, and an elastic locking block 53 is movably disposed within the groove 54. The elastic locking block 53 includes an elastic element 531 and a locking connector 532 connected to each other. The locking connector 532 has a first position and a second position. When the locking connector 532 is in the first position, part of the locking connector 532 is located outside the groove 54, and the elastic element 531 is in a natural state. When the locking connector 532 is in the second position, the locking connector 532 is completely located within the groove 54, and the elastic element 531 is in a compressed state and has a tendency to move the locking connector 532 closer to the first position. In actual operation, the elastic element 531 is a spring, which has a simple structure, is easy to obtain materials, and has low cost.

[0044] Specifically, in the initial state, the locking connector 532 of the connecting part 51 is in the first position. During the process of inserting the connecting part 51 into the connecting slot 31, the locking connector 532 abuts against the inner wall of the connecting slot 31, and the inner wall of the connecting slot 31 presses the locking connector 532 to the second position. At this time, the connecting part 51 can continue to be inserted into the connecting slot 31 until the locking connector 532 moves to the position of the slot 32. Driven by the elastic element 531, the locking connector 532 extends out from the slide groove 54 and enters the slot 32, thereby realizing the locking connection between the connecting part 51 and the connecting slot 31. Conversely, when the connecting part 51 is removed from the connecting slot 31, the operating switch 33 is pushed from the outer wall of the connecting slot 31. The operating switch 33 presses the locking connector 532 to the second position, and the locking connector 532 is disengaged from the slot 32. That is, the connecting part 51 is de-locked from the connecting slot 31. At this time, the connecting part 51 can be removed from the connecting slot 31. The operation is simple and convenient.

[0045] In one embodiment, the end face of the connector 532 facing away from the contact portion 52 is set as an arc surface, that is, the side of the connector 532 that contacts the inner wall of the connecting slot 31 is an arc surface, which facilitates the inner wall of the connecting slot 31 to press the connector 532, making it easier for the connecting portion 51 to be inserted into the connecting slot 31. Furthermore, the end face of the connector 532 facing the contact portion 52 is set as a flat surface, that is, after the connector 532 is engaged in the slot 32, the flat end of the connector 532 abuts against the side of the slot 32 adjacent to the opening of the connecting slot 31. This flat design ensures a smooth abutment between the connector 532 and the slot 32, preventing the edge of the slot 32 from abutting against the connector 532 and causing the connector 532 to detach from the slot 32. This prevents the connecting portion 51 from detaching from the connecting slot 31, ensuring a stable connection between the connecting portion 51 and the connecting slot 31, thus ensuring a stable connection between the connecting module 5 and the connecting member 3, and ensuring the stability of the panel 2 during power-on testing.

[0046] In one embodiment, such as Figure 6 As shown, the cross-section of the connecting slot 31 is square. Slots 32 are provided on the two adjacent side walls of the connecting slot 31. Specifically, slots 32 are provided on all four side walls of the connecting slot 31. Two elastic locking blocks 53 are provided, respectively located on opposite sides of the connecting part 51. When the connecting part 51 engages with the connecting slot 31, the two elastic locking blocks 53 engage in the slots 32 on the opposite sides of the connecting slot 31. For example... Figures 6 to 8 As shown, the connecting module 5 has a third position and a fourth position. When the connecting module 5 is in the third position, the elastic snap-fit ​​block 53 snaps into one set of opposing slots 32. When the connecting module 5 is in the fourth position, the elastic snap-fit ​​block 53 snaps into the other set of opposing slots 32. Therefore, depending on the position and orientation of the pads 21 on the panel 2, the connecting module 5 can be connected to the connecting member 3 in different positions so that the connecting probe 6 on the connecting module 5 can correspond to the pads 21 on the panel 2. That is, by adjusting the snap-fit ​​positions, the position of the connecting probe 6 is adjusted to correspond to the position of the pads 21 on the panel 2.

[0047] In one embodiment, the side of the contact portion 52 facing the panel 2 is designated as the contact surface 521, and multiple connecting probes 6 are provided, arranged in a matrix on the contact surface 521. In actual operation, the connecting probes 6 are arranged in a matrix of two rows horizontally and six columns vertically on the contact surface 521, such as... Figure 7 As shown, when the connecting module 5 is in the third position, the horizontal direction is the first direction, and the vertical direction is the second direction. And as... Figure 8 As shown, when the connecting module 5 is in the fourth position, the horizontal direction is the second direction and the vertical direction is the first direction.

[0048] Of course, in other embodiments, the number and distribution of the connection probes 6 are not limited to the arrangement described above, such as... Figure 9 As shown, a matrix arrangement with two rows horizontally and four columns vertically can also be used. Furthermore, as... Figure 10 As shown, an irregular array arrangement can also be used, where the spacing between adjacent connection probes 6 is not exactly the same. As long as a connection module 5 with corresponding connection probes 6 can be used according to the position of the pad 21 to achieve power-on testing of the panel 2, such a design falls within the protection scope of this utility model.

[0049] In one embodiment, such as Figure 11 As shown, multiple connectors 3 are distributed in a matrix on the connecting plate 1, and the multiple connectors 3 cover the entire connecting plate 1. Thus, regardless of the size of the panel 2, the corresponding connector 3 can be found at the position of the pad 21 on the panel 2. The connecting module 5 is then installed on the corresponding connector 3 to connect the panel 2 to the connecting plate 1 through the connecting module 5, thereby enabling the panel 2 to be powered on for testing. The fixture in this embodiment has strong versatility.

[0050] 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.
