Description

Technical Field

[0001] This utility model belongs to the field of keyboard backlight module testing technology, specifically relating to a testing auxiliary mechanism for keyboard color backlight modules. Background Technology

[0002] Computer keyboard backlight modules are usually installed under the keyboard to provide visual illumination, thereby improving the overall usability of the keyboard in poor lighting conditions. There are usually solid color backlight modules and multi-color backlight modules. After the keyboard backlight module is assembled, it usually needs to be tested for lighting effect.

[0003] Currently, testing of existing keyboard backlight modules is generally done manually by visual inspection, which cannot accurately grasp the brightness differences between different LEDs. Furthermore, as testing personnel work longer hours, eye fatigue increases, and color sensitivity decreases, compromising the reliability of the test results. Therefore, those skilled in the art have provided a solution to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a testing auxiliary mechanism for keyboard color backlight modules, which can solve the problems mentioned in the background technology, which are generally completed by manual visual inspection, making it impossible to accurately grasp the brightness differences of different LEDs. Moreover, as the working time of the testing personnel increases, their eye fatigue deepens and their sensitivity to color decreases, making it impossible to guarantee the reliability of the test results.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A testing auxiliary mechanism for a keyboard color backlight module includes a base. A disc is rotatably mounted on the outer top surface of the base. Support plates arranged in a circular array are fixed to the outer peripheral sidewall of the disc. A receiving block is fixed to the outer top surface of each of the four support plates. A placement slot for placing a test keyboard is opened on the outer top surface of each of the four receiving blocks. A through-type opening is symmetrically opened on the inner sidewall of each of the four sets of placement slots. A light-shielding plate is rotatably mounted inside each of the four pairs of openings. A connecting plate is fixedly mounted to the right end of the outer sidewall of the base. A through-type vertical groove is opened on the left outer sidewall of the connecting plate. A lead screw is rotatably mounted on the inner bottom surface of the vertical groove. A moving block is threaded onto the outer peripheral sidewall of the lead screw. One end of the moving block extends to the left outer sidewall of the connecting plate and is fixed with a visual inspection probe for detecting the light effect of the backlight module by bolts. A square opening adapted to the visual inspection probe is opened on the outer top surface of each of the four light-shielding plates. A rotating component for driving the disc to rotate is provided inside the base.

[0007] The present invention is further configured such that: the rotating assembly includes a square cavity formed inside the base, a rotating shaft is rotatably mounted on the inner bottom surface of the square cavity, one end of the rotating shaft extends rotatably to the outer top surface of the base and is fixedly connected to the outer bottom surface of the disc, and a worm gear is fixed inside the square cavity and on the outer peripheral sidewall of the rotating shaft.

[0008] The present invention is further configured such that: a worm gear is rotatably mounted on the inner wall of the square cavity, and a drive motor is fixedly mounted on the rear outer wall of the base; one end of the worm gear extends rotatably to the rear outer wall of the base and is fixedly connected to the output end of the drive motor.

[0009] The present invention is further configured such that: a second drive motor is fixed on the outer top surface of the connecting plate, and one end of the lead screw extends rotatably to the outer top surface of the connecting plate and is fixedly connected to the output end of the second drive motor.

[0010] The present invention is further configured such that: clamping plates are symmetrically provided inside the four sets of placement slots; electric push rods are fixedly installed on the opposite outer side walls of the four receiving blocks; and the output ends of the four pairs of electric push rods slide into the interior of the placement slots and are respectively fixedly connected to the clamping plates.

[0011] The present invention is further configured such that: each of the four corners of the outer bottom surface of the base is fixed with a support leg, and each of the four support legs has a through screw hole on its outer bottom surface.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a testing auxiliary mechanism for keyboard color backlight modules. Through the setting of a receiving block, a placement slot, a clamping plate, and an electric push rod, the test keyboard can be limited. With the assistance of a light shield, the interference of external light sources on the keyboard light effect is reduced. At the same time, through the cooperation of a lead screw, a moving block, a visual inspection probe, and a square opening, the differences caused by manual visual inspection are avoided, thereby improving the accuracy of the test results.

[0021] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one testing auxiliary mechanism or several specific implementations of this utility model for a keyboard color backlight module, and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1 , 2 As shown, a testing auxiliary mechanism for a keyboard color backlight module includes a base 1. Support legs 18 are fixed at each of the four corners of the base 1's outer bottom surface. Each of the four support legs 18 has a through-hole on its outer bottom surface. Tightening the bolts in the screw holes allows the base 1 to be fixed in a designated position via the support legs 18, thus ensuring stability during subsequent operation. A disc 2 is rotatably mounted on the top surface of the base 1. Support plates 3 arranged in a circular array are fixed to the outer periphery of the disc 2. Support blocks 4 are fixed to the top surfaces of the four support plates 3. Placement slots 5 for placing the test keyboard are opened on the top surfaces of the four support blocks 4. The keyboard backlight module to be tested is placed sequentially in the placement slots 5. Clamping plates 16 are symmetrically arranged inside each of the four placement slots 5. Electric push rods 17 are fixedly installed on the opposite outer walls of the four receiving blocks 4. The output ends of the four pairs of electric push rods 17 slide into the interior of the placement slots 5 and are fixedly connected to the clamping plates 16 respectively. Then, the electric push rods 17 are activated to extend, thereby clamping the two sides of the keyboard backlight mold with the clamping plates 16 to prevent displacement during testing and affect the test results. The inner walls of the four sets of placement slots 5 are symmetrically provided with through-hole openings 6. The light shields 7 are rotatably installed inside the four pairs of openings 6. Then, the light shields 7 are driven to rotate in the openings 6 and cover the outer top surface of the receiving blocks 4 to reduce the interference of external light during the test and also to protect the keyboard backlight module.

[0023] like Figure 1 , 2 As shown in Figure 3, a connecting plate 8 is fixedly installed on the right end of the outer wall of the base 1. A through-type vertical groove 9 is opened on the left outer wall of the connecting plate 8. A lead screw 10 is rotatably installed on the inner bottom surface of the vertical groove 9. A moving block 11 is threaded onto the outer peripheral side wall of the lead screw 10. One end of the moving block 11 extends to the left outer wall of the connecting plate 8 and is fixed with a visual inspection probe 12 for detecting the light effect of the backlight module by bolts. (The visual inspection probe 12 is a visual inspection camera probe. The light effect detection of the keyboard backlight module is performed by a visual inspection camera, which is existing technology and will not be described in detail in this article.) (Explanation) Each of the four light-shielding plates 7 has a square opening 13 on its outer top surface that is compatible with the visual inspection probe 12. A second drive motor 15 is fixed on the outer top surface of the connecting plate 8. One end of the lead screw 10 extends to the outer top surface of the connecting plate 8 and is fixedly connected to the output end of the second drive motor 15. The second drive motor 15 is controlled and started to drive the lead screw 10 to rotate in a circle inside the vertical groove 9, thereby pushing the moving block 11 to move downward along the vertical groove 9, so that the visual inspection probe 12 can be inserted into the square opening 13 to perform light effect testing on the keyboard backlight module.

[0024] like Figure 2 , 3 As shown in Figure 4, the base 1 has a rotating assembly 14 for driving the disc 2 to rotate. The rotating assembly 14 includes a square cavity 141 inside the base 1. A rotating shaft 142 is rotatably mounted on the inner bottom surface of the square cavity 141. One end of the rotating shaft 142 extends rotatably to the outer top surface of the base 1 and is fixedly connected to the outer bottom surface of the disc 2. A worm gear 143 is fixed inside the square cavity 141 and on the outer peripheral sidewall of the rotating shaft 142. A worm 144 is rotatably mounted on the inner sidewall of the square cavity 141. A drive motor 145 is fixedly installed on the rear outer wall. One end of the worm gear 144 extends to the rear outer wall of the base 1 and is fixedly connected to the output end of the drive motor 145. The drive motor 15 is controlled and started to drive the worm gear 144 to rotate inside the square cavity 141, thereby driving the worm wheel 143 to drive the rotating shaft 142 to rotate synchronously. This drives the disc 2 to rotate circumferentially along the outer top surface of the base 1 at a certain speed, thereby realizing the cyclic detection operation of the keyboard backlight mold and improving work efficiency.

[0025] The working principle of this utility model is as follows: First, the keyboard backlight module to be tested is placed in the placement slot 5. Then, the electric push rod 17 is activated, using the clamping plate 16 to limit the keyboard backlight module's position. Next, the light shield 7 is driven to cover the outer top surface of the receiving block 4 to reduce interference from external light during the testing process. Then, the drive motor 15 is activated, driving the worm gear 144 to engage with the worm wheel 143, causing the rotating shaft 142 to drive the disc 2 to rotate circumferentially along the outer top surface of the base 1 at a certain speed. This is achieved through a position detection device (a prior art device, not described or shown in detail here) installed on the connecting plate 8. The working principle and structural features are used to detect whether the keyboard backlight module has rotated to the designated position. Then, the drive motor 15 is started to drive the lead screw 10 to move the moving block 11 downward, so that the vision detection probe 12 can be inserted into the square opening 13 to test the light effect of the keyboard backlight module. (It should be noted that all electrical components mentioned in the text are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming, and then it can operate normally according to the above steps. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.)

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
