Description

Technical Field

[0001] This utility model relates to the field of backlight production equipment technology, and in particular to a rotating lighting device for solving the problem that the extremely short exposed part of the FPC of backlight products makes it difficult to light up conventional lighting fixtures. Background Technology

[0002] In the backlight production process, the conventional operation requires fixing the FPC with tape before lighting it up. However, for some products, the exposed portion of the FPC after being wrapped with protective tape is extremely short, making it impossible to pull the gold fingers on the FPC into the visible area for operation. This directly results in conventional lighting fixtures being unable to easily and effectively light up these products, severely impacting the efficiency and continuity of backlight production. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned technical problems and provide a rotating lighting device.

[0004] To achieve the above technical objectives and requirements, the technical solution adopted by this utility model is as follows: a rotating lighting device, including a base; rotating shaft modules are symmetrically arranged on the base, a product placement mold is arranged between the two rotating shaft modules, a rotating pressing module is arranged diagonally on the product placement mold, a clamping module is arranged at the bottom of the product placement mold, and a support pad module is arranged on the base. By moving and adjusting the position of the support pad module, the angle between the support pad module and the product placement mold is changed, thereby realizing multi-angle foreign object inspection and brightness abnormality inspection of the product's light-emitting surface.

[0005] Preferably, the support plate module includes a guide rail a, which is mounted on the base. A slider a is slidably fitted on the guide rail a. A handle mounting plate is provided on the slider a. An ascending rod and a handle are respectively provided on the handle mounting plate. A support plate is provided on the top of the ascending rod. By driving the handle, the slider a is moved along the guide rail a, so that the support plate moves to a position below the product placement mold to form a support or to disengage from the support.

[0006] Preferably, the rotating shaft module includes a bearing mounting plate, which is mounted on the base. Bearing a and bearing b are respectively provided on the left and right sides of the upper end of the bearing mounting plate. One end of the shoulder bolt a passes through bearing a, bearing mounting plate and bearing b in sequence and is locked to the side of the product placement mold. The product placement mold rotates around the shoulder bolt a to a preset angle.

[0007] Preferably, the product placement mold rotates around the shoulder bolt a at an angle of 0°-360° to accommodate various angles required for testing.

[0008] Preferably, the rotary clamping module includes a rotary seat with two countersunk holes. A magnet is installed in each countersunk hole. A limit spring is installed on the rotary seat. A shoulder bolt b passes through a washer a, a limit spring, the rotary seat, and the washer b in sequence and is connected to the outer frame of the product placement mold. The product placement mold has a magnet mounting position corresponding to the countersunk hole of the rotary seat. The magnetic attraction between the magnet in the countersunk hole of the rotary seat and the magnet mounting position of the product placement mold is used to lock and fix the product to be tested.

[0009] Preferably, the rotating seat of the rotary clamping module rotates around the shoulder bolt b at an angle of 0°-360°. By adjusting the tightness of the shoulder bolt b, the position of the rotary clamping module can be rotated arbitrarily to adapt to different product testing requirements.

[0010] Preferably, the clamp module includes a clamp body a, a clamp body b, a pressure spring, and a return spring. A guide rail b is provided at the bottom of the product placement mold. Guide rail blocks are provided at the bottom of the outer frame of the product placement mold corresponding to both ends of the guide rail b. A slider b slidably engages with the guide rail b. A clamp mounting plate is provided on the slider b. The clamp body a is provided on the clamp mounting plate. The clamp body a is connected to the clamp body b via a positioning shaft. The pressure spring is located between the clamp body a and the clamp body b. One end of the return spring is connected to the clamp mounting plate, and the other end is connected to the guide rail block.

[0011] Preferably, the clamp body a and clamp body b are provided with magnet mounting holes at corresponding positions, and magnets are provided in the magnet mounting holes. By the elastic force of the pressure spring or the attraction force of the magnet in the magnet mounting hole, the gold finger part of the FPC light strip of the product to be tested is clamped to realize the lighting operation.

[0012] Compared with the traditional structure, the beneficial effects of this utility model are: 1. This utility model eliminates the need to pull the FPC light strip. The shorter exposed part of the FPC can be lit by rotating the product without damaging the exposed part of the FPC. This solves the problem of conventional fixtures not being compatible, simplifies the lighting operation process of short exposed FPC products, eliminates the need for additional fixing or adjustment steps, reduces working time and labor costs, and helps to improve the continuity and overall efficiency of backlight production.

[0013] 2. The product is locked by magnetic adsorption of the rotating clamping module, and the support plate module provides stable support for the mold after rotation. This double protection ensures that the product will not fall off or shake during rotation and lighting, making it suitable for high-precision operations such as electrical testing.

[0014] 3. The clamp body a and clamp body b are reserved with magnet mounting holes, which can be used to install magnets. The magnetic attraction force of the magnets enhances the clamping force and further improves the contact stability between the gold finger and the clamp module. This can adapt to backlight products with different precision requirements, meet diverse production needs, and improve the versatility and practicality of the device.

[0015] 4. By moving and adjusting the position of the support pad module, the angle between the support pad module and the product placement mold can be changed, enabling multi-angle foreign object inspection and brightness abnormality inspection of the product's light-emitting surface.

[0017] The present invention will be further described below.

[0018] See attached document Figure 1-4A rotating lighting device includes a base 1; rotating shaft modules 3 are symmetrically arranged on the base 1, and a product placement mold 6 is arranged between the two rotating shaft modules 3. A rotating pressing module 4 is arranged diagonally on the product placement mold 6, and a clamping module 5 is arranged at the bottom of the product placement mold 6. A support pad module 2 is arranged on the base 1. By moving and adjusting the position of the support pad module 2, the angle between the support pad module 2 and the product placement mold 6 is changed, thereby realizing multi-angle foreign object inspection and brightness abnormality inspection of the product's light-emitting surface.

[0019] In this preferred embodiment, the support pad module 2 includes a guide rail a21, which is disposed on the base 1. A slider a22 is slidably engaged with the guide rail a21. A handle mounting plate 23 is disposed on the slider a22. An ascending rod 25 and a handle 24 are respectively disposed on the handle mounting plate 23. A support plate 26 is disposed on the top of the ascending rod 25. By driving the handle 24, the slider a22 is moved along the guide rail a21, so that the support plate 26 moves to a position below the product placement mold 6 to form a support or to disengage from the support position.

[0020] In this preferred embodiment, the rotating shaft module 3 includes a bearing mounting plate 31, which is disposed on the base 1. Bearings a32 and b34 are respectively disposed on the left and right sides of the upper end of the bearing mounting plate 31. One end of the shoulder bolt a33 passes through the bearing a32, the bearing mounting plate 31 and the bearing b34 in sequence and is locked to the side of the product placement mold 6. The product placement mold 6 rotates around the shoulder bolt a33 to a preset angle.

[0021] In this preferred embodiment, the product placement mold 6 rotates around the shoulder bolt a33 at an angle of 0°-360° to accommodate various angles required for testing.

[0022] In this preferred embodiment, the rotary clamping module 4 includes a rotary seat 42 with two countersunk holes 46. A magnet 47 is disposed in each countersunk hole 46. A limit spring 43 is disposed on the rotary seat 42. A shoulder bolt b45 passes through a washer a44, a limit spring 43, the rotary seat 42, and a washer b41 in sequence and is connected to the outer frame of the product placement mold 6. The product placement mold 6 has a magnet mounting position corresponding to the countersunk hole 46 of the rotary seat. The product to be tested is locked and fixed by the magnetic attraction between the magnet 47 in the countersunk hole 46 of the rotary seat and the magnet mounting position of the product placement mold 6.

[0023] In this preferred embodiment, the rotating seat of the rotary clamping module 4 rotates around the shoulder bolt b45 at an angle of 0°-360°. By adjusting the tightness of the shoulder bolt b45, the position of the rotary clamping module 4 can be rotated arbitrarily to adapt to different product testing requirements.

[0024] In this preferred embodiment, the clamp module 5 includes a clamp body a51, a clamp body b54, a pressure spring 53, and a return spring 56. A guide rail b59 is provided at the bottom of the product placement mold 6. Guide rail blocks 57 are provided at the bottom of the outer frame of the product placement mold 6 corresponding to both ends of the guide rail b59. A slider b58 is slidably fitted onto the guide rail b59. A clamp mounting plate 55 is provided on the slider b58. The clamp body a51 is provided on the clamp mounting plate 55. The clamp body a51 is connected to the clamp body b54 via a positioning shaft 52. The pressure spring 53 is disposed between the clamp body a51 and the clamp body b54. One end of the return spring 56 is connected to the clamp mounting plate 55, and the other end is connected to the guide rail block 57.

[0025] In this preferred embodiment, the clamp body a51 and clamp body b54 are provided with magnet mounting holes at corresponding positions, and magnets are provided in the magnet mounting holes. By the elastic force of the pressure spring or the attraction force of the magnet in the magnet mounting hole, the gold finger part of the FPC light strip of the product to be tested is clamped to realize the lighting operation.

[0026] In practice, the backlight product to be tested is placed smoothly into the product placement mold 6 to ensure that the product does not shift or shake within the product placement mold 6. Push the handle 24 to move the slider a22 along the guide rail a21, so that the support plate 26 is away from the area below the product placement mold 6, so as to avoid interfering with the rotation of the product placement mold 6. Hold the product placement mold 6 with both hands and slowly apply force to rotate the product placement mold 6 around the shoulder bolt a33 of the rotating shaft module 3. Continue to rotate to the 180° position. At this time, the FPC light strip of the product is facing upward. Stop the rotation. The magnet 47 in the countersunk hole 46 of the rotating seat is completely attached to the magnetic surface of the corresponding magnet mounting position of the product placement mold 6. The product is firmly locked in the mold, effectively preventing the product from falling off during subsequent rotation. Push the handle 24 of the support plate module 2 to move the slider a22 along the guide rail a21 toward the product placement mold 6 until the support plate 26 is completely moved below the product placement mold 6. The surface of the support plate 26 is in close contact with the bottom of the product placement mold 6 to provide stable support for the mold and prevent the mold from shaking during subsequent lighting operations. Holding the clamp body a51 and clamp body b54 of the clamp module 5, gently press them to the sides to separate the two bodies. Align the gold fingers of the FPC light strip with the clamping area between the two bodies. Under the reaction force of the elastic reset of the pressure spring 53, the clamp body a51 and clamp body b54 automatically clamp the gold fingers of the FPC light strip. The positioning shaft 52 holds the two bodies to prevent them from separating, ensuring a stable clamping state. At this time, the FPC light strip is powered on and illuminated. If this illuminating operation is used for processes such as electrical testing that require high clamping force, the clamp body a51 and clamp body b54 are reserved with magnet mounting holes. Magnets can be installed in the magnet mounting holes, and the magnetic attraction force of the magnets can enhance the clamping force, further improving the contact stability between the gold fingers and the clamp module. After the operation is completed, pull the handle 24 to move the slider a22 in the opposite direction along the guide rail a21, so that the support plate 26 is disengaged from under the product placement mold 6 and in contact with the support state. Rotate the product placement mold 6 again in the opposite direction of the previous 180° rotation, and push the product placement mold 6 to slowly rotate 180° around the shoulder bolt a33 of the rotating shaft module 3 until the product placement mold 6 returns to the initial position. At this time, the light-emitting surface of the product is facing upward, and the product reset is completed. If further work is required on the light-emitting surface of the product, the handle 24 can be pushed again to move the support plate 26 under the mold to form support. After the work is completed, rotate the rotating seat 42 of the rotating clamping module 4 in the opposite direction to release the magnetic lock, and the product can be taken out from the product placement mold.
