[0035] Example:

[0036] Figure 1 This is a first view of a darkroom structure provided by an embodiment of the utility model in a closed state. Figure 2 This is a second view of a darkroom structure in a closed state provided by an embodiment of the utility model, combined with Figure 1 and Figure 2 As shown, the darkroom structure 100 includes a bottom plate 1 , a movable plate 2 , a darkroom cover 3 and a light source 4 .

[0037] Figure 3 Schematic diagram of the structure of the bottom plate provided by the embodiment of the utility model, such as Figure 3 As shown, the bottom plate 1 is used to be mounted in parallel on the carrier plate of the fixture, and the bottom plate 1 has a first positioning surface 11 , and the first positioning member 111 is arranged on the first positioning surface 11 .

[0038] Figure 4 Schematic diagram of the structure of the movable plate provided by the embodiment of the utility model, such as Figure 4 As shown, the movable plate 2 is hinged on the bottom plate 1 , and has a second positioning surface 21 for abutting against the first positioning surface 11 , and has a second positioning member 211 on the second positioning surface 21 for aligning with the first positioning member 111 .

[0039] The darkroom cover 3 is arranged on the movable plate 2, and the light source 4 is arranged in the darkroom cover 3. When the first positioning surface 11 and the second positioning surface 21 are in contact with each other, the darkroom cover 3 and the carrier plate form a darkroom space, and the light emitting surface of the light source 4 faces one side of the carrier plate.

[0040] For a darkroom structure provided by an embodiment of the utility model, before the display panel is tested for the light source 4, the base plate 1 is first installed on the carrier plate in parallel according to the appropriate position on the carrier plate of the crimping fixture. Then, the display panel to be tested is placed flat on the carrier plate, and the display panel is lit by the crimping piece (pogo) on the crimping fixture. Then, after the flipping movable plate 2 is in place, the darkroom cover 3 is brought to flip over the display panel, at which time the darkroom cover 3 and the carrier plate will form a darkroom space and seal the display panel. In addition, when the flip movable plate 2 is in place, the first positioning surface 11 of the base plate 1 and the second positioning surface 21 of the movable plate 2 are fitted (at this time, it can be regarded as the movable plate 2 buckled, and the movable plate 2 is fitted with the base plate 1), and under the action of the first positioning piece 111 and the second positioning piece 211 alignment, the first positioning surface 11 and the second positioning surface 21 are locked, and the locking of the movable plate 2 and the light source 4 can be achieved, so as to avoid the problem of the movable plate 2 vibrating during the test and causing the light source 4 to shift or vibrate, and the abnormal photosensitivity test data can be avoided. Finally, the light source 4 is turned on, thereby ultimately ensuring that the photosensitivity test of the display panel is achieved and avoiding abnormal photosensitivity test data.

[0041] That is to say, the darkroom structure provided by the embodiment of the utility model can effectively avoid the problem that the movable plate 2 vibrates during the test and causes the light source 4 to shift or vibrate, thereby ensuring the photosensitivity test of the display panel and avoiding abnormal photosensitivity test data.

[0042] It should be noted that after the test is completed, the movable plate 2 is flipped over by a large external force to overcome the locking force between the first positioning member 111 and the second positioning member 211, and the darkroom cover 3 is flipped over and removed from above the display panel (see FIG. Figure 5 ), thereby releasing the seal of the darkroom space on the display panel, so as to facilitate replacement of the next display panel to be tested.

[0043] Exemplarily, when the first positioning surface 11 of the bottom plate 1 and the second positioning surface 21 of the movable plate 2 are in contact, the light emitting plane of the light source 4 is exactly parallel to the bottom plate 1 , that is, the light emitting plane of the light source 4 can vertically illuminate the display panel on the carrier.

[0044] In addition, the darkroom space can also seal the crimping parts or part of the crimping parts at the same time, and the utility model does not impose any restrictions on this.

[0045] Exemplarily, the light emitting plane of the light source 4 is parallel to the second positioning surface 21, the bottom plate 1 has a positioning plate, the first positioning surface 11 is located on the positioning plate, and the first positioning surface 11 is parallel to the bottom plate 1. In other words, by controlling the first positioning surface 11 to be parallel to the bottom plate 1 and the light emitting plane of the light source 4 to be parallel to the second positioning surface 21, it is ensured that when the first positioning surface 11 and the second positioning surface 21 are attached, the light emitting plane of the light source 4 is parallel to the bottom plate 1.

[0046] Exemplarily, the movable plate 2 has a wiring groove 23 for wiring the light source 4 .

[0047] In one implementation of the present invention, Figure 5 As shown, the first positioning member 111 may be a first magnet, and the second positioning member 211 may be a second magnet, that is, the first positioning surface 11 and the second positioning surface 21 are automatically brought into close contact with each other through the magnetic force between the first magnet and the second magnet, thereby achieving locking of the two.

[0048] In other implementations of the utility model, the first positioning member may also be an elastic projection, and the second positioning member may also be a slot, that is, the elastic projection is inserted into the slot, and the elastic projection is deformed and locked in the slot to achieve the same close contact between the first positioning surface 11 and the second positioning surface 21, thereby achieving the locking of the two.

[0049] It should be noted that the first positioning member may also be a slot, and the second positioning member may be a corresponding elastic protrusion.

[0050] In addition, in other embodiments of the present invention, the first positioning member and the second positioning member may also be adhesive tapes that are bonded to each other, and the present invention does not limit this.

[0051] Furthermore, the bottom plate 1 has a travel switch 12 for generating a control signal. The travel switch 12 is arranged opposite to the movable plate 2 . The travel switch 12 is configured such that when the first positioning surface 11 and the second positioning surface 21 are in contact with each other, the movable plate 2 triggers the travel switch 12 .

[0052] In the above embodiment, when the movable plate 2 is flipped to the engaged state, the movable plate 2 just triggers the travel switch 12 and sends a corresponding control signal, thereby reminding the operator to flip the movable plate 2 into place for the next operation.

[0053] In this embodiment, the darkroom cover 3 includes a darkroom top cover 31 and a plurality of curtains 32 . The darkroom top cover 31 is detachably mounted on the movable plate 2 , and the plurality of curtains 32 are detachably mounted on the darkroom top cover 31 along the circumference of the darkroom top cover 31 .

[0054] It is easy to understand that when testing display panels of different sizes, it is sufficient to select a darkroom top cover 31 and a curtain 32 of corresponding size according to the size of the display panel, thereby forming a darkroom space of corresponding size without replacing structures such as the bottom plate 1, the movable plate 2 and the light source 4, thereby achieving the commonality of some structures and reducing the testing cost.

[0055] Exemplarily, the darkroom top cover 31 has a plurality of detachably arranged pressure strips 33 , and each curtain 32 is sandwiched between the corresponding pressure strip 33 and the darkroom top cover 31 , so that the curtain 32 can be conveniently installed through the pressure strip 33 and the curtain 32 can be easily replaced.

[0056] It is easy to understand that the darkroom top cover 31 supports the tops of the multiple screens 32, and the screens 32 extend downward under the action of gravity. The screens 32 have good ductility, and their bottoms fit tightly with the carrier plate, with good sealing performance.

[0057] Exemplarily, the darkroom top cover 31 includes a top plate and a plurality of enclosures, which are circumferentially arranged on the top plate. The enclosures can not only realize the installation of the curtain 32, but also realize the connection with the movable plate 2, so as to facilitate the installation of the curtain 32 on the darkroom top cover 31 and conveniently connect the movable plate 2.

[0058] For example, the bottom plate 1, the movable plate 2 and the darkroom top cover 31 can all be made of aluminum alloy, which can not only meet the strength requirements but also meet the precision requirements. The bottom plate 1 is provided with a plurality of waist-shaped holes arranged at intervals, and a connecting bolt 15 is inserted in each waist-shaped hole, so as to realize the parallel connection between the bottom plate 1 and the carrier plate, and facilitate the adjustment of the position of the bottom plate 1.

[0059] In an implementation of the present invention, the light source 4 can be directly disposed on the inner wall of the darkroom cover 3 .

[0060] In another implementation of the present invention, Figure 6 Schematic diagram of the assembly of the connecting plate and the light source mounting plate provided in the embodiment of the utility model, such as Figure 6 As shown, the darkroom structure also includes a connecting plate 5 and a light source mounting plate 6. The connecting plate 5 is vertically fixed to the end of the movable plate 2 and connected to the darkroom cover 3. The light source mounting plate 6 is installed on the connecting plate 5, and the light source mounting plate 6 is arranged parallel to the movable plate 2.

[0061] In the above embodiment, the connecting plate 5 serves to connect the movable plate 2 , while the connecting plate 5 and the light source mounting plate 6 serve to support the light source 4 .

[0062] Exemplarily, the connecting plate 5 is detachably connected to the darkroom cover 3 by bolts, and the connecting plate 5 can realize detachable support for the darkroom cover 3, so that there is no need to disassemble the light source 4 when replacing the darkroom cover 3, thereby improving the disassembly efficiency. In addition, the connecting plate 5 and the light source mounting plate 6 are both located in the darkroom space.

[0063] It should be noted that in other embodiments of the present invention, the connecting plate 5 can also be arranged at an angle on the movable plate 2. It is only necessary to ensure that the light source mounting plate 6 is arranged parallel to the movable plate 2, so that when the first positioning surface and the second positioning surface are in contact (that is, the movable plate 2 is buckled at this time), the light-emitting plane of the light source 4 can be arranged parallel to the base plate 1.

[0064] Exemplarily, the darkroom top cover 31 is fixed to the connecting plate 5 by bolts. The connecting plate 5 and the light source mounting plate 6 are arranged in a T shape. The light source 4 is fixed to the light source mounting plate 6 by bolts.

[0065] Furthermore, the connecting plate 5 has a first waist-shaped hole 51 extending in a direction perpendicular to the movable plate 2 , and an adjusting bolt 52 is movably inserted in the first waist-shaped hole 51 . The screw of the adjusting bolt 52 passes through the first waist-shaped hole 51 and then engages with the light source mounting plate 6 through a thread.

[0066] In the above embodiment, the height of the light source 4 can be conveniently adjusted by adjusting the position of the light source mounting plate 6 to meet the requirements of different heights of the light source 4 for display panels of different sizes (different thicknesses).

[0067] It is easy to understand that when the height of the light source 4 needs to be adjusted, first loosen the adjusting bolt 52, then move the light source mounting plate 6 according to the height requirement, and the light source mounting plate 6 is moved to the appropriate position with the light source 4, and finally tighten the adjusting bolt 52.

[0068] Exemplarily, the connecting plate 5 has a scale extending in the vertical direction, and the scale is located on one side of the first waist-shaped hole 51 to serve as an indicator for adjustment.

[0069] Specifically, the connecting plate 5 has two second waist-shaped holes 53 extending in a direction perpendicular to the movable plate 2, the first waist-shaped hole 51 is located between the two second waist-shaped holes 53, and the light source mounting plate 6 has two guide columns 61 parallel to the movable plate 2, and each guide column 61 is slidably inserted into the corresponding second waist-shaped hole 53.

[0070] It is easy to understand that, through the cooperation of multiple guide posts 61 and multiple guide holes, a guiding role can be played in the adjustment of the light source 4 to prevent the light source mounting plate 6 from rotating or shifting during the adjustment process, thereby changing the direction of the light-emitting surface of the light source 4.

[0071] In this embodiment, the movable plate 2 has a first hinge plate 22, and the bottom plate 1 has a second hinge plate 13. The first hinge plate 22 and the second hinge plate 13 are rotatably connected via a rotating shaft with a damper.

[0072] In the above embodiment, the first hinge plate 22 serves to connect the movable plate 2, while the second hinge plate 13 serves to connect the bottom plate 1. In addition, the hinge is realized by the rotating shaft, and the damper correspondingly arranged on the rotating shaft can increase the damping during the rotation process to prevent the movable plate 2 from rotating easily (the first hinge plate 22, the second hinge plate 13 and the rotating shaft can be regarded as a damping hinge as a whole).

[0073] Exemplarily, the base plate 1 has a boss 16 , and the second hinge plate 13 is located on the boss 16 .

[0074] In addition, the bottom plate 1 is provided with a limit block 14. When the movable plate 2 is flipped open, the limit block 14 can limit the movable plate 2 so that the movable plate 2 can be opened at a suitable angle, for example, 120° or 140°, to facilitate the next flip.

[0075] Exemplarily, the darkroom structure 100 further includes a light source controller 7, which is electrically connected to the light source 4. The light source controller 7 can adjust the brightness of the light source 4, and its maximum illumination can reach 20k.

[0076] The embodiment of the utility model provides a crimping jig, which comprises a carrier plate, a crimping component and a dark chamber structure as described above, wherein the crimping component and a bottom plate 1 are arranged on the carrier plate at intervals.

[0077] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
