[0030] The embodiment of the present utility model provides a screen lighting mechanism, which is mainly used for lighting a mobile phone screen.

[0031] like Figure 1-Figure 4 As shown, a screen lighting mechanism includes a needle mold 1, which includes an upper pressure plate 11 and a lower base plate 12. The upper pressure plate 11 is rotatably connected to the lower base plate 12. The lower base plate 12 is provided with a probe board, and a plurality of probes are provided on the probe board. The conductive interface of the screen is placed on the probe board, and the upper pressure plate 11 is rotated and pressed downward toward the lower base plate 12 so that the conductive interface of the screen is electrically contacted with the probe.

[0032] The needle mold 1 is the core component of the lighting mechanism, which includes an upper pressure plate 11 and a lower base plate 12. These two plates constitute the main body of the lighting mechanism. The upper pressure plate 11 is rotatably connected to one side of the lower base plate 12, so that the upper pressure plate 11 rotates relative to the lower base plate 12. The probe plate is a plate fixed to the lower base plate 12, on which a plurality of probes are installed. These probes are used to make electrical contact with the conductive interface of the screen so as to transmit electrical signals during the lighting process, thereby lighting the screen. When the upper pressure plate 11 is pressed down, the conductive interface of the screen will fully contact the probes, thereby achieving electrical connection. This connection closes the lighting circuit, making it possible to check whether the screen can be properly lit.

[0033] In the present invention, the upper pressing plate 11 and the lower base plate 12 are rotatably arranged, and the probe plate is arranged on the lower base plate 12. The screen can be lit up by only pressing the upper pressing plate 11, which is simple to operate and low in cost.

[0034] In one embodiment, the upper pressing plate 11 is provided with a convex pressing block that corresponds to the position of the probe board. The convex pressing block can concentrate force on the location of the screen conductive interface, ensuring good electrical contact between the screen conductive interface and the probes on the probe board. This can avoid lighting failure or inaccurate lighting due to poor contact. Moreover, compared to directly applying pressure over a large area with the upper pressing plate 11, the convex pressing block can make the structural design more streamlined, eliminating the need to apply pressure across the entire surface of the upper pressing plate 11, thereby reducing the complexity of materials and processing.

[0035] The lower base plate 12 is provided with a mounting groove, and the probe plate is fixedly installed in the mounting groove. The probe plate is fixed in the mounting groove by screws. With such a design, the mounting groove provides a recessed space in which the probe plate is placed, which can effectively protect the probe plate and the probe from damage caused by external impact or friction, thereby extending the service life of the probe plate. At the same time, the probe plate is installed in the mounting groove, which makes it more convenient to disassemble and assemble the probe plate. When the probe plate needs to be replaced or maintained, it can be simply taken out of or put into the mounting groove, reducing the complexity and time cost of maintenance. In addition, the mounting groove partially embeds the probe plate into the lower base plate 12. Such a design can reduce the thickness of the entire lighting mechanism, making the equipment more compact and suitable for environments with limited space.

[0036] like Figure 3 As shown, the upper pressing plate 11 and the lower base plate 12 are penetrated by a hinge shaft 13, and a torsion spring is sleeved on the hinge shaft 13. One end of the torsion spring is connected to the upper pressing plate 11, and the other end of the torsion spring is connected to the lower base plate 12. The function of the torsion spring is to provide an upward rebound force. When the upper pressing plate 11 is pressed down, the torsion spring is twisted and stores energy. Once the pressure is released, the torsion spring will quickly return to its original position, ensuring that the upper pressing plate 11 can automatically reset. This rebound force helps maintain the rapid response of the device, ensuring that the device can be quickly ready for the next lighting after each lighting.

[0037] like Figure 4 As shown, the screen lighting mechanism also includes a clamping assembly 2, which includes a support block 21, a rotating pressure plate 22, a rotating support arm 23 and a pressure plate cylinder 24. The lower end of the rotating support arm 23 is hinged to the support block 21, and the upper end of the rotating support arm 23 is hinged to the rotating pressure plate 22. The output shaft of the pressure plate cylinder 24 is hinged to the rotating pressure plate 22. The support block 21 is provided with a support platform 211, and the needle mold 1 is placed on the surface of the support platform 211; the pressure plate cylinder 24 works to drive the rotating pressure plate 22 to rotate and contact the upper pressure plate 11, so as to push the upper pressure plate 11 to rotate and press downward toward the lower base plate 12.

[0038] Through the coordinated operation of the support block 21, the rotating support arm 23, the rotating pressure plate 22, and the pressure plate cylinder 24, the entire pressing process can be very precisely controlled. The pressure plate cylinder 24 acts as a driving force source, transmitting the motion of the rotating pressure plate 22 and the rotating support arm 23 to move the upper pressure plate 11 downward in a controlled manner and apply pressure. By adjusting the output force of the pressure plate cylinder 24, the pressure applied by the upper pressure plate 11 can be flexibly adjusted to meet the pressing force requirements of different screen types or different lighting requirements. This adjustability makes the device more widely applicable.

[0039] It should be noted that the hinge position of the pressure plate cylinder 24 and the upper pressure plate 11 is located behind the hinge position of the rotating support arm 23 and the upper pressure plate 11. When the output shaft of the pressure plate cylinder 24 is extended, it will drive the rotating pressure plate 22 to flip downward, and the rotating pressure plate 22 will apply pressure to the upper pressure plate 11. When the output shaft of the pressure plate cylinder 24 is retracted, it will drive the rotating pressure plate 22 to flip downward. At this time, the rotating pressure plate 22 will be away from the upper pressure plate 11. The upper pressure plate 11 is not subjected to the pressure of the rotating pressure plate 22, and quickly returns to its original position under the action of the rebound force generated by the torsion spring, and can be quickly ready for the next lighting. Through such a design, the lighting efficiency can be greatly improved and the maneuverability of the lighting process is improved.

[0040] like Figure 3 As shown, the clamping assembly 2 also includes a forward and backward moving adjustment module 25, which is arranged between the needle mold 1 and the support platform 211. The forward and backward moving adjustment module 25 includes a forward and backward moving dovetail block 251, a dovetail seat 252 and a forward and backward moving adjustment handle 253. The dovetail seat 252 is provided with a dovetail groove conveniently arranged along the front and back. The forward and backward moving dovetail block 251 is slidingly connected to the dovetail groove, and the forward and backward moving adjustment handle 253 is transmission-connected to the forward and backward moving dovetail block 251. The bottom of the dovetail seat 252 is fixedly connected to the support platform 211, and the top of the forward and backward moving dovetail block 251 is fixedly connected to the lower base plate 12.

[0041] The forward-backward moving dovetail block 251 is a block capable of sliding in the forward-backward direction, with its top fixedly connected to the lower base plate 12. The dovetail seat 252 is a fixed structure with a dovetail groove that matches the shape of the dovetail block, allowing the dovetail block to slide along the groove. The bottom of the dovetail seat 252 is fixedly connected to the support platform 211. The forward-backward moving adjustment handle 253 is used to manually control the forward-backward movement of the dovetail block within the dovetail groove. By turning the handle, the dovetail block can be driven to move along the dovetail groove of the dovetail seat 252.

[0042] The forward and backward movement adjustment module 25 allows the operator to precisely control the forward and backward position of the lower base plate 12 (and thus the upper pressure plate 11 and the probe plate) by adjusting the handle. This is critical for ensuring accurate alignment between the lighting probe and the conductive interface of the screen, thereby improving the accuracy and reliability of lighting. In addition, by manually adjusting the handle, the operator can easily fine-tune the position without complicated operating steps. This design not only improves operational convenience, but also allows for quick response to different lighting needs, saving time and manpower.

[0043] like Figure 2 As shown, the screen lighting mechanism further includes a support frame 3, which includes a bottom base plate 31, a horizontal support plate 32, and a support column 33. The horizontal support plate 32 is provided above the support frame 3, and the support column 33 is connected between the bottom base plate 31 and the horizontal support plate 32. The bottom base plate 31 serves as a mounting component for the pressing assembly 2. When lighting, the horizontal support plate 32 serves as a support component for the screen. The screen is placed horizontally on the horizontal support plate 32, with the end of the screen with the conductive interface facing the needle mold 1.

[0044] like Figure 4 As shown, the clamping assembly 2 also includes a left-right movable sliding module 26, which includes left-right sliding rails 261, left-right motion sliders 262 and left-right motion adjustment handles 263 arranged along the left-right directions. The left-right motion sliders 262 are slidingly connected to the left-right slide rails 261, the left-right motion adjustment handles 263 are transmission-connected to the left-right motion sliders 262, the top of the left-right motion sliders 262 is fixedly connected to the support block 21, and the left-right slide rails 261 are fixedly connected to the support frame 3.

[0045] The left and right sliding modules allow the operator to precisely adjust the position of the support block 21 in the left and right directions, ensuring precise docking with the lower pressure plate or other components. This precision is crucial for ensuring good contact between the lighting probe and the conductive interface of the screen, helping to improve lighting accuracy and consistency.

[0046] like Figure 4 As shown, the bottom seat plate 31 is provided with a support mounting block 34 , and the top of the support mounting block 34 is fixedly connected to the bottom of the left and right slide rails 261 .

[0047] The design of the support mounting block 34 can provide additional support and stability, facilitate the installation and fixation of the slide rail, and ensure that the left and right slide rails 261 will not shake or move during operation.

[0048] The embodiment of the present invention further provides a screen module detection device, including the above-mentioned screen lighting mechanism. Except for the above-mentioned screen lighting mechanism, the remaining structures are the same as those of the common screen module detection devices in the prior art, and will not be described in detail here.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
