Description

Technical Field

[0001] The present application relates to the technical field of laser repair of display panels, and in particular to a lighting device and laser repair equipment. Background Art

[0002] During the display panel production process, a lighting test is typically performed on the panel. This involves applying power to the panel using a lighting device. After the device receives a test signal, the panel displays different images. The resulting images can be used to determine if the panel has defects.

[0003] The lighting device typically illuminates the display panel by contacting it with probes. Display panels typically have contacts on only one side. For a display panel placed on a stage, the contacts may be located on either the top or bottom surface of the display panel. In this case, the lighting device is equipped with both a first probe and a second probe. The first probe is used to contact the contacts on the top surface of the display panel, and the second probe is used to contact the contacts on the bottom surface of the display panel. This ensures that the display panel remains powered regardless of its placement.

[0004] To ensure good electrical contact, the second probe will apply a certain force to the contact point on the lower surface of the display panel when it contacts the contact point. However, the display panel is prone to warping at this time, and the electrical contact may fail.

[0005] In the related art, a pressing component is provided in the lighting device to press the display panel downward to prevent the display panel from warping. However, this makes the structure of the lighting device too complicated and the production cost of the lighting device higher. Utility Model Content

[0054] The second housing of the second motor 351 is fixed to the first mounting bracket 230 via fasteners, and the second rotating shaft of the second motor 351 is in transmission connection (e.g., via a coupling, a speed reducer, etc.) with the lower end of the second screw rod 341. Thus, when the second motor 351 is powered on, it can drive the second fixing base 320 to move in the first direction.

[0055] In other embodiments, the second drive member 350 may also be a cylinder or a linear motor, and the second transmission assembly 340 may also be a rack and pinion mechanism, a synchronous wheel and belt mechanism, a sprocket and chain mechanism, a crank slider mechanism, or other mechanisms. In addition, the second probe assembly 300 may also be mounted on the connecting base 410 instead of the first mounting bracket 230.

[0056] Specifically, refer to Figures 1 to 3 The driving assembly 400 further includes a base 440 and a third transmission assembly 420, and the third driving member 430 includes a third motor 431.

[0057] The second housing of the third motor 431 is fixed to the base 440 via fasteners, and the second rotating shaft of the third motor 431 is in transmission connection with the left end of the third screw rod 421 (e.g., via a coupling, a reducer, etc.). Thus, when the third motor 431 is powered on, it can drive the connecting base 410 to move in the second direction.

[0058] In other embodiments, the third driving member 430 may also be a cylinder or a linear motor, and the third transmission assembly 420 may also be a gear rack mechanism, a synchronous wheel and belt mechanism, a sprocket and chain mechanism, a crank slider mechanism or other mechanisms.

[0059] In addition, refer to Figure 3 To ensure smoother movement of the first probe assembly 200 and the second probe assembly 300 mounted on the connecting base 410, the driving assembly 400 further includes a sliding assembly 450. Two sliding assemblies 450 are provided, one sliding assembly 450 being disposed on the upper side of the base 440 and the other sliding assembly 450 being disposed on the lower side of the base 440. Both sliding assemblies 450 are used to guide the movement of the connecting base 410 in the second direction.

[0060] The sliding assembly 450 includes a fourth slide rail 451 and a fourth slider 452. The length of the fourth slide rail 451 is arranged along the second direction.

[0061] Reference Figure 4 In some embodiments of the present application, projections of the first probe 210 and the second probe 310 along the first direction do not overlap.

[0062] The projections of the first probe 210 and the second probe 310 along the first direction do not overlap. Therefore, when the second probe 310 contacts the contact 110 on the lower surface of the display panel 100 , the first probe 210 avoids the display panel 100 , thereby reducing the probability of the display panel 100 being scratched by the first probe 210 .

[0063] Reference Figure 4 In the above embodiment, it is assumed that the first direction is perpendicular to the second direction, and the first probe 210 and the second probe 310 are staggered along the second direction.

[0064] By staggering the first probe 210 and the second probe 310 along the second direction, the projections of the first probe 210 and the second probe 310 along the first direction may not overlap, and one of the first probe 210 and the second probe 310 may be brought into contact with the contact 110 of the display panel 100 by simply controlling the movement distance of the connecting base 410 along the second direction by the third driving member 430.

[0065] Reference Figure 5 In the above embodiment, it is assumed that the first direction, the second direction and the third direction are perpendicular to each other, and the first probe 210 and the second probe 310 are also staggered along the third direction.

[0066] By further staggering the first probes 210 and the second probes 310 along the third direction, when the second probes 310 contact the contacts 110 on the lower surface of the display panel 100 , the probability of the first probes 210 contacting the display panel 100 is lowered, thereby facilitating protection of the display panel 100 .

[0067] Reference Figure 2 In some embodiments of the present application, the first driving member 250 is also used to drive the second probe assembly 300 to move along the first direction.

[0068] The first driving member 250 can simultaneously drive the first probe 210 and the second probe 310 to move along the first direction. The positions of the first probe 210 and the second probe 310 can be adjusted synchronously and quickly, which is conducive to quickly aligning the display panel 100 with the accommodating space 120 between the second fixing base 320 and the first fixing base 220, and lighting up the display panel 100 faster.

[0069] It should be noted that, in order for the first driving member 250 to drive the second probe assembly 300 to move along the first direction, the second probe assembly 300 only needs to be installed on the first mounting bracket 230 . The specific installation structure is described above.

[0070] Reference Figure 2 In some embodiments of the present application, the first probe assembly 200 and the second probe assembly 300 are both installed on the connecting seat 410 .

[0071] At this time, the driving assembly 400 can simultaneously drive the first probe assembly 200 and the second probe assembly 300 to move along the second direction, and the display panel 100 can quickly enter the accommodating space 120 between the second fixing seat 320 and the first fixing seat 220, so that the display panel 100 can be lit faster.

[0072] Reference Figure 2 In some embodiments of the present application, the first fixing seat 220 and the second fixing seat 320 are transparent.

[0073] When the first fixing base 220 and the second fixing base 320 are both transparent, it is more convenient to observe the positions of the first probe 210 and the second probe 310 , to check the contact between the first probe 210 and the contact 110 of the display panel 100 , and to check the contact between the second probe 310 and the contact 110 of the display panel 100 .

[0074] Reference Figure 2 In an improved solution of the above embodiment, the material of the first fixing seat 220 is acrylic or glass, and the material of the second fixing seat 320 is acrylic or glass.

[0075] Acrylic or glass is relatively easy to obtain, and the use of acrylic or glass materials is conducive to reducing the production cost of the lighting device.

[0076] Reference Figure 6 and Figure 7 The laser repair device according to the second embodiment of the present application includes a lighting device, a carrier 510 and a laser device 520. The carrier 510 is used to carry the display panel 100. The laser device 520 is used to emit laser to perform laser repair on the display panel 100.

[0077] The laser repair equipment according to the embodiment of the present application has at least the following beneficial effects: by using the above-mentioned lighting device, it is helpful to simplify the structure of the laser repair equipment.

[0078] Reference Figure 6 In some embodiments of the present application, the carrier 510 can absorb or release the display panel 100.

[0079] By adsorbing the display panel 100 , one of the first probe 210 and the second probe 310 can stably contact the contact 110 of the display panel 100 , and the lighting process is less prone to errors.

[0080] Specifically, the carrier 510 is provided with adsorption holes, which are connected to a vacuum air source, and further adsorb or release the display panel 100 .
