[0029] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0030] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0031] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them.

[0032] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific implementation manners.

[0033] As shown Figure 1 in the figure, a tape film 200 is attached around the display panel 100. The tape film 200 has light transmittance to provide mechanical protection and dust prevention, and at the same time can detect whether there is damage around the display panel 100. Existing test fixtures include a fixture platform 300. One end of the backlight module 100 abuts against a positioning member 400 and is positioned on the fixture platform 300 by a plurality of clamps 500. Due to the asynchronous movement of the plurality of clamps 500, during the loading and unloading process of the display panel 100, the tape film 200 is easily torn, causing the display panel 100 to be scratched. In addition, the circuit 600 of the display panel 100 is connected to an external power supply module 700, and the circuit 600 is easily pulled and damaged during the test process.

[0034] Referring to Figures 2 to 8 , an embodiment of the present invention provides a display panel test fixture, including a fixture body 10, a positioning component 20, a clamping component 30, and a power supply component 40. The fixture body 10 includes a placement area 101. The positioning component 20 is disposed on the circumferential edge of the placement area 101 and is used to abut against the display panel located in the placement area 101. The clamping component 30 is used to clamp or release the display panel. There are at least two groups of clamping components 30, and each group of clamping components 30 is arranged at intervals around the circumference of the placement area 101. At least two groups of clamping components 30 can move synchronously. The power supply component 40 is disposed on the fixture body 10 to supply power to the display panel.

[0035] During the test, the display panel is placed in the placement area 101 so that a part of the edge of the display panel abuts against the positioning component 20, and the positioning component 20 plays a preliminary positioning role for the display panel. During the process of switching all the clamping components 30 to the clamping state, at least two groups of clamping components 30 move synchronously, so that the display panel is clamped and locked. The power supply component 40 is electrically connected to the power cord of the display panel to test the display panel. Since at least two groups of clamping components 30 move synchronously, when disassembling the display panel, at least two groups of clamping components 30 are synchronously switched to the release state, avoiding scratching the display panel due to the difference in clamping and release timings. Since the power supply component 40 is disposed on the fixture body 10, when connecting to the power cord of the display panel, it is avoided that the power cord is pulled and damaged due to the movement or flipping of the backlight module.

[0036] The placement area 101 is used to place the display panel, and the shape of the placement area 101 can be set according to the shape of the display panel. In this embodiment, the placement area 101 is rectangular for placing a rectangular display panel. The rectangular placement area 101 is convenient for processing and production and has high versatility. Since the placement area 101 is rectangular, the placement area 101 has four sides. The positioning component 20 is used to abut against the edge of the display panel. The positioning component 20 can be arranged at one side of the placement area 101 or at two adjacent sides of the placement area 101. The arrangement of the positioning component 20 does not affect the placement of the display panel in the placement area 101. The clamping component 30 can be arranged at one side of the placement area 101, or at two sides of the placement area 101, or at three sides or four sides of the placement area 101.

[0037] In this embodiment, the placement area 101 is rectangular, the positioning components 20 are distributed on two adjacent sides of the placement area 101, and the clamping components 30 are arranged on the other two adjacent sides of the placement area 101. The positioning component 20 and the clamping component 30 are reasonably arranged without space waste. The positioning component 20 and the clamping component 30 cooperate to make the position of the display panel stable.

[0038] In some embodiments, as Figure 8 shown, the placement area 101 is rectangular, the positioning component 20 is distributed on one side of the placement area 101, and the clamping components 30 are arranged on the other three sides of the placement area 101. In other embodiments, the placement area 101 is rectangular, the positioning component 20 is distributed on two adjacent sides of the placement area 101, and the clamping components 30 are arranged on three sides of the placement area 101. That is to say, at one side of the placement area 101, both the positioning component 20 and the clamping component 30 are arranged, as long as it is ensured that the positioning component 20 and the clamping component 30 do not interfere with each other.

[0039] The positioning component 20 is integrally formed with or detachably connected to the jig body 10. When the positioning component 20 is detachably connected to the jig body 10, it is convenient for installation, disassembly and replacement. Specifically, it can be snap connection, magnetic attraction connection or screw connection.

[0040] The positioning component 20 includes a first positioning block 21, and the first positioning block 21 extends a first set length along the length direction of the placement area 101. The positioning component 20 further includes a second positioning block 22, and the second positioning block 22 extends a second set length along the width direction of the placement area 101, or at least two second positioning blocks 22 are provided, and the respective second positioning blocks 22 are spaced along the width direction of the placement area 101.

[0041] The clamping assembly 30 is provided with at least two groups, and the number of the clamping assembly 30 can be set according to actual needs. Exemplarily, the clamping assembly 30 is provided with two groups, three groups, or more than three groups. At least two groups of clamping assemblies 30 can move synchronously, and the number of the clamping assemblies 30 that move synchronously can be set according to actual needs. Exemplarily, when the clamping assembly 30 is provided with two groups, the two groups of clamping assemblies 30 move synchronously. When the clamping assembly 30 is provided with three groups, the two groups of clamping assemblies 30 move synchronously or the three groups of clamping assemblies 30 move synchronously.

[0042] Exemplarily, all the clamping assemblies 30 move synchronously to ensure the synchronization of all the clamping assemblies 30, and further avoid scratches on the display panel due to differences in clamping and releasing timing.

[0043] In some embodiments, the clamping assembly 30 can move from top to bottom to clamp the display panel. In order to facilitate the disassembly of the display panel to prevent interference with the clamping assembly 30, in this embodiment, the clamping assembly 30 includes a rotating shaft 31 and a clamping jaw 32, the rotating shaft 31 is rotatably connected to the fixture body 10, the clamping jaw 32 is fixedly arranged on the rotating shaft 31, and at least two rotating shafts 31 are transmission-connected. The clamping jaw 32 is driven to move between the clamping position and the release position by the rotation of the rotating shaft 31, and the structure is simple and easy to assemble. When the clamping jaw 32 is in the clamping position, the clamping jaw 32 can clamp the display panel. When the clamping jaw 32 is in the release position, the clamping jaw 32 releases the display panel and the clamping jaw 32 is away from the placement area 101 to prevent interference with the placement of the display panel.

[0044] One shaft 31 or two or more shafts 31 may be provided along one side of the placement area 101, and adjacent shafts 31 provided coaxially may be connected via a coupling. One clamp 32 or two or more clamps 32 may be provided on each shaft 31.

[0045] For at least two groups of clamping assemblies 30 that move synchronously, the corresponding two rotating shafts 31 move synchronously, and the two rotating shafts 31 are transmission-connected. Exemplarily, all rotating shafts 31 move synchronously, and adjacent rotating shafts 31 are transmission-connected.

[0046] In this embodiment, a rotating shaft 31 is provided along one side of the placement area 101, and the rotating shaft 31 extends along the edge of the placement area 101. Adjacent rotating shafts 31 are perpendicular to each other, and each rotating shaft 31 is provided with a bevel gear 37, and adjacent rotating shafts 31 are connected to each other through the meshing of the bevel gears 37. When one rotating shaft 31 rotates around its own axis, the meshing bevel gears 37 can drive other rotating shafts 31 to rotate, thereby realizing synchronous rotation of all rotating shafts 31. The transmission connection is realized by the meshing of the bevel gears 37, which has a compact structure, occupies less space, and is easy to assemble.

[0047] At least two clamping jaws 32 are provided on at least part of the rotating shaft 31, and the adjacent clamping jaws 32 are fixedly connected by a connecting rod 33. By providing the connecting rod 33, the adjacent clamping jaws 32 are firmly fixed, ensuring the stability of the synchronous movement of each clamping jaw 32. The connecting rod 33 is detachably connected to the clamping jaw 32, which is convenient for installation, disassembly and replacement. Specifically, it can be a snap connection or a screw connection.

[0048] Exemplarily, the connecting rod 33 and the clamping jaw 32 are detachably connected through a connecting member 36. Both ends of the connecting rod 33 are provided with mounting portions 331, mounting holes are provided in the mounting portions 331, threaded holes are provided on the clamping jaw 32, and the connecting member 36 passes through the mounting hole and is connected to the threaded hole to lock the connecting rod 33 and the clamping jaw 32.

[0049] Exemplarily, on two adjacent sides of the placement area 101, one rotating shaft 31 is provided on each side, the two rotating shafts 31 are perpendicular to each other, two clamping jaws 32 are provided on each rotating shaft 31, and the two clamping jaws 32 on each rotating shaft 31 are fixedly connected by a connecting rod 33.

[0050] In some embodiments, the rotating shaft 31 is manually driven by a human hand. For example, a handle is provided at one end of the rotating shaft 31, and the rotating shaft 31 can be driven to rotate by holding the handle. For the rotating shafts 31 that move synchronously, a common handle can be shared. When all the rotating shafts 31 move synchronously, only one handle needs to be provided to drive all the rotating shafts 31 to rotate synchronously.

[0051] In some embodiments, the rotating shaft 31 is electrically driven, and the clamping assembly 30 further includes a driving member for driving the rotating shaft 31 to rotate, reducing the labor intensity. For the rotating shafts 31 that move synchronously, a common driving member can be shared. When all the rotating shafts 31 move synchronously, only one driving member needs to be provided to drive all the rotating shafts 31 to move synchronously. The driving member can be a motor, and the motor shaft of the motor can be directly connected to the rotating shaft 31 or connected to the rotating shaft 31 through a transmission mechanism.

[0052] In some embodiments, the clamping assembly 30 further includes a driving member for driving the rotating shaft 31 to rotate. The driving member is an electromagnet. An electromagnet can be provided for each rotating shaft 31, or all the rotating shafts 31 can share a common electromagnet. The electromagnet is energized or de-energized to drive the rotating shaft 31 to rotate. For example, the electromagnet has a telescopic rod, the telescopic rod is connected to a rack, a gear is provided on the rotating shaft 31, and the gear meshes with the rack. The electromagnet is energized or de-energized to drive the telescopic rod to reciprocate linearly.

[0053] In some embodiments, the clamping assembly 30 further includes a torsion spring, and the torsion spring is disposed between the rotating shaft 31 and the jig body 10. By providing the torsion spring, the torsion spring applies an elastic force to the rotating shaft 31, and this elastic force causes the clamping jaw 32 on the rotating shaft 31 to have a tendency to press against the display panel, increasing the stability of the display panel.

[0054] In some embodiments, the clamping assembly 30 further includes a flexible member 34 disposed on the jaw 32 for abutting against the display panel. By providing the flexible member 34, the jaw 32 is in flexible contact with the display panel, avoiding impact damage to the display panel. The flexible member 34 can be a silicone layer, a rubber layer, or a sponge layer, and is not limited herein.

[0055] In some embodiments, the clamping assembly 30 further includes a magnetic member 35 disposed on the jaw 32 for magnetically attracting and locking the jaw 32 in the clamping position with the fixture body 10. By providing the magnetic member 35, the jaw 32 is stable in the clamping position, and the clamping of the jaw 32 on the display panel is more secure. The fixture body 10 can be made of a magnetically attractable material, or the fixture body 10 includes a magnetic attracting portion that can be magnetically attracted to the magnetic member. Exemplarily, mounting protrusions are provided on the inner wall of the jaw 32, and the magnetic member is disposed on the mounting protrusions.

[0056] The shape of the jaw 32 can be set according to actual needs. In this embodiment, the jaw 32 includes a connecting portion and a clamping portion. The connecting portion is connected to the rotating shaft 31, and the clamping portion is used for clamping the display panel. An obtuse angle is formed between the connecting portion and the clamping portion. Both the magnetic member 35 and the flexible member 34 are disposed on the clamping portion.

[0057] The fixture body 10 further includes a power supply area 102 disposed on one side of the placement area 101, and the power supply assembly 40 is disposed in the power supply area 102. By providing the power supply area 102, it is convenient to install the power supply assembly 40 and avoid interference with the placement area 101. Specifically, the fixture body 10 is an integrally formed structure, and a first positioning block 21 is provided on one side of the placement area 101. The power supply area 102 is disposed on the same side as the first positioning block 21. Since the area of the power supply area 102 is smaller than the area of the placement area 101 and is located on one side of the placement area 101, the fixture body 10 is substantially in a P-shaped structure.

[0058] The power supply assembly 40 includes a conductive sheet 41 and a pressing member 42. The pressing member 42 includes a conductive contact. The pressing member 42 is movably connected to the fixture body 10 such that the conductive contact contacts or separates from the conductive sheet 41. When the conductive contact contacts the conductive sheet 41, the power supply assembly 40 is in a power supply state. During use, one end of the power cord of the display panel is placed on the conductive sheet 41, and pressing the pressing member 42 can make the conductive contact contact the conductive sheet 41. The end of the power cord is clamped between the conductive contact and the conductive sheet 41, playing a positioning role for the power cord and achieving stable power supply.

[0059] Among them, the conductive sheet 41 can be a copper sheet. Exemplarily, the pressing member 42 is rotatably connected to the jig body 10. The pressing member 42 is fixedly arranged on the pin shaft 44. The pin shaft 44 is rotatably connected to the jig body 10 and a torsion spring is arranged between the two, so that the pressing member 42 clamps the power cord.

[0060] A positioning groove 104 is formed on the jig body 10, and a positioning protrusion 421 is arranged on the pressing member 42. When the pressing member 42 rotates to contact the conductive sheet 41, the positioning protrusion 421 is inserted into the positioning groove 104 to play a positioning role and further prevent the power cord from shifting.

[0061] A guiding groove 103 is formed on the jig body 10 for placing the power cord of the display panel to prevent the power cord from shifting and being pulled.

[0062] The power supply assembly 40 further includes a power supply circuit 43, and the power supply circuit 43 can be arranged inside the jig body 10. The power supply circuit 43 includes but is not limited to wires, circuit boards, etc. In some embodiments, as Figure 8 shown, the power supply circuit 43 is arranged on the surface of the jig body 10. The power supply circuit 43 is electrically connected to the conductive sheet 41 to realize power supply.

[0063] In some embodiments, as Figure 8 shown, a protective film 50 is arranged in the placement area 101. The protective film 50 extends circumferentially around the placement area 101. The display panel can be in contact with the protective film 50 so that the protective film 50 adheres to the display panel. By using each clamping assembly 30 to clamp synchronously, the protective film 50 can be accurately, conveniently, evenly and quickly attached to the display panel to achieve a good attachment effect. The protective film 50 plays a role in dust prevention and mechanical protection for the display panel. When the placement area 101 is rectangular, the protective film 50 can extend in a rectangular ring shape, or the protective film 50 can be arranged only on three sides of the placement area 101, that is, the protective film 50 extends in a U shape.

[0064] To facilitate laying the protective film 50 in the placement area 101, a plurality of positioning posts 60 are arranged on the jig body 10, and positioning holes are arranged at corresponding positions on the protective film 50. When laying the protective film 50, the positioning posts 60 can be passed through the positioning holes. To avoid interference between the positioning posts 60 and the display panel, the positioning posts 60 can be removed after laying the protective film 50. It is also possible to set the positioning posts 60 to be slidably connected to the jig body 10. The positioning posts 60 can slide between an extended position and a retracted position. In the extended position, the positioning posts 60 protrude from the surface of the placement area 101. In the retracted position, the positioning posts 60 are hidden inside the jig body 10. The sliding of the positioning posts 60 can be controlled by a cylinder, a linear motor, a hydraulic cylinder, etc.

[0065] The above display panel testing fixture improves the degree of automation in the operation process, making the assembly process simpler and faster, and further improving the yield rate of the display panel and significantly reducing the damage rate.

[0066] This embodiment also provides a display panel testing method, which uses the above display panel testing fixture and includes: when all the clamping components 30 are in the released state, placing the display panel in the placement area 101 so that part of the edge of the display panel abuts against the positioning component 20; during the process of switching all the clamping components 30 to the clamping state, at least two groups of clamping components 30 move synchronously so that the display panel is clamped and locked; electrically connecting the power supply line of the display panel through the power supply component 40 to test the display panel. Because the above display panel testing fixture is used, at least two groups of clamping components 30 move synchronously, avoiding scratching the display panel due to the difference in the clamping and releasing time sequences.

[0067] The display panel being clamped and locked means that all the clamping components 30 are switched to the clamping state to fix the display panel, and subsequent operations such as testing will be carried out next. When only one group or some groups of clamping components 30 are in the clamping state and the remaining groups of clamping components 30 are not in the clamping state, it cannot be called clamped and locked. Exemplarily, when there are three groups of clamping components 30, all three groups of clamping components 30 are switched to the clamping state, and the display panel is clamped and locked.

[0068] Exemplarily, during the process of switching all the clamping components 30 to the clamping state, all the clamping components 30 move synchronously.

[0069] Placing the display panel in the placement area 101, specifically, the display panel can be manually moved to the fixture body 10 or can be moved to the fixture body 10 by an existing robotic arm, abutting the two sides of the display panel against the positioning component 20. After the clamping component 30 clamps the display panel, place the end of the power supply line at the conductive sheet 41, press the pressing member 42 so that the conductive contact touches the conductive sheet 41, and the end of the power supply line is clamped between the conductive contact and the conductive sheet 41, then the display panel can be powered.

[0070] After the test is completed, disconnect the connection between the power supply component 40 and the power supply line of the display panel. During the process of switching all the clamping components 30 to the released state, at least two groups of clamping components 30 move synchronously to remove the display panel in the placement area 101. Among them, the pressing member 42 can be manually toggled so that the pressing member 42 moves away from the conductive sheet 41 under the action of the torsion spring, then the connection between the power supply component 40 and the power supply line of the display panel can be disconnected. Exemplarily, during the process of switching all the clamping components 30 to the released state, all the clamping components 30 move synchronously.

[0071] During the process of placing the display panel in the placement area 101, the edge portion of the surface of the display panel facing the placement area 101 abuts against the protective film 50 provided in the placement area 101, causing the protective film 50 to adhere to the display panel. Before placing the display panel, first lay the protective film 50 in the placement area 101, and insert the positioning posts 60 through the positioning holes in the protective film 50 to ensure the accurate laying position of the protective film 50. After removing the positioning posts 60 or moving the positioning posts 60 to the retracted position, place the display panel in the placement area 101 of the jig body 10, and the protective film 50 can be adhered to the display panel.

[0072] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
