Description

Technical Field

[0001] The invention relates to the field of testing of color backlight modules, and in particular to a method for detecting a vibration-type notebook computer keyboard flexible backlight module. Background Art

[0002] The laptop keyboard backlight module is installed under the laptop keyboard, and it emits light to enhance the possibility of using the keyboard in scenes with low ambient light. In order to ensure that the chip components in the laptop keyboard flexible backlight module work properly, the laptop keyboard flexible backlight module will be subjected to functional testing and false welding testing during factory testing. In the traditional false welding test, the back of the RGB-LED lamp is squeezed by pressing the probe down, and the brightness value of the RGB-LED lamp is measured to determine whether there is false welding in the flexible backlight module when the backlight module is slightly deformed. This test method cannot accurately control the downward pressure of the pressing probe. If the downward pressure is applied when the pressing probe is aged and the friction between the contact surface of the needle sleeve and the needle body increases, the downward pressure is too large, which can easily cause indentations or poor appearance of the test sample.

[0003] Therefore, a new technical solution for detecting the flexible backlight module of the laptop keyboard is needed to solve the current testing method of squeezing the back of the RGB-LED lamp by pressing down the probe.

[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0025] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0026] The present application provides a method for detecting a vibration-type notebook computer keyboard flexible backlight module, such as Figure 1 As shown, the following steps are included:

[0027] Step 100, placing a test sample of the laptop keyboard flexible backlight module in a test sample placement slot on the upper plane of the test device body, and making the RGB-LED lamp of the test sample fall into the brightness sensor window, pressing the flip plate on the upper plane of the test device body, and making the test sample power supply spring on the flip plate press on the gold finger of the test sample, the test sample power supply spring supplies power to the test sample, making the RGB-LED lamp of the test sample emit light, and the light emitted by the RGB-LED lamp is transmitted to the brightness sensor through the brightness sensor window, and the data processing unit receives the data of the RGB-LED lamp collected by the brightness sensor, wherein the data processing unit and the brightness sensor are arranged inside the test device body, and the brightness sensor window is arranged in the test sample placement slot;

[0028] like Figure 2 and Figure 3 As shown, the test sample of the laptop keyboard flexible backlight module is set in a T shape, and the end of the vertical bar on the front of the test sample extending outward is provided with a gold finger. Figure 2 The gold finger 12 is arranged on the front of the test sample 23. The gold finger includes 4 terminals, and a sample identification code 11 is arranged on the vertical bar on the front of the test sample. Figure 3 A plurality of RGB-LED lamps 13 are evenly arranged on the horizontal strip on the back of the test sample (the RGB-LED lamps are fixed on the back of the test sample by welding); (the sample identification code is a two-dimensional code that records the basic information of the test sample and is used for subsequent sorting and traceability of the product. The information of the test sample can be traced back through the sample identification code. If there is a problem with the test sample, the problem in the production stage can be further traced through the sample identification code); during the detection process, the test sample is placed face up on the test sample placement slot 9.

[0029] Among them, Figure 4As shown, it further includes: a flap shaft 17 and a test device body magnet 19 are also provided on the test device body 5, and the flap 16 is installed on the flap shaft 17, and the flap 16 can rotate along the flap shaft 17; a flap magnet 18 is provided on the flap 16, and the shape and position of the flap magnet 18 are adapted to the shape and position of the test device body magnet 19, so that when the flap 16 is flipped and pressed on the upper plane of the test device body 5, the flap magnet 18 and the test device body magnet 19 are engaged, and the test sample power supply spring 24 on the flap is tightly pressed on the gold finger 12 of the test sample. (The above setting, by pressing the test sample power supply spring piece 24 on the flip plate tightly against the gold finger of the test sample placed in the test sample placement slot 9, ensures that the contact between the test sample power supply spring piece and the gold finger is normal, and ensures the normal progress of the detection); four terminals are set on the test sample power supply spring piece 24 on the flip plate, and the four terminals of the test sample power supply spring piece are adapted to the shape and position of the four terminals of the gold finger of the test sample. The test sample power supply spring piece 24 on the flip plate is pressed on the gold finger of the test sample, which means that: the four terminals of the test sample power supply spring piece on the flip plate are in close contact with the four terminals of the gold finger of the test sample. (The four terminals of the test sample power supply spring are adapted to the shapes and positions of the four terminals of the test sample's gold fingers, which can ensure the close connection between the test sample power supply spring and the test sample's gold fingers, thereby improving the accuracy of detection and making the process reliable); a brightness sensor circuit board 22 is also provided inside the test device body 5, and a brightness sensor 21 is mounted on the brightness sensor circuit board 22 by welding.

[0030] like Figure 4 As shown, a bending plate 15 is also installed at the end of the flap 16. By bending the bending plate 15, the flap 16 can rotate along the flap shaft 17 (the rotation of the flap can be limited by the setting of the bending plate, so that the flap can be rotated accordingly or maintain its position as required).

[0031] Among them, the test sample placement groove is set on the upper plane of the test device body at a position directly below the corresponding downward pressure platform (the above setting can ensure that the downward pressure platform is pressed down on the test sample, and the high-frequency vibration generated by the vibration motor is transmitted to the test sample through the downward pressure platform, ensuring the correct conduct of the test), wherein the shape of the groove of the test sample placement groove is set to match the shape of the test sample, the test sample is placed in the test sample placement groove, and a plurality of brightness sensor windows are distributed in the test sample placement groove, and the shape and position of each brightness sensor window are adapted to the shape and position of each RGB-LED lamp of the corresponding test sample. (The shape of the groove of the test sample placement groove matches the shape of the test sample, which can enable the test sample to be accurately positioned during the detection process, and facilitates the correct operation of the position of the close engagement between the test sample power supply spring and the four terminals of the test sample's gold finger in the next step, and ultimately ensures the normal operation of the test)

[0032] Step 110, the data processing unit controls the downward pressure platform to descend so that the downward pressure platform is pressed down on the test sample. After starting the vibration motor on the downward pressure platform, the vibration motor generates high-frequency vibration and transmits it to the test sample through the downward pressure platform. The data processing unit receives the data of the RGB-LED lamp after the high-frequency vibration collected by the brightness sensor again; the data processing unit determines whether there is a cold solder joint or false solder joint in the test sample by judging whether the data of the RGB-LED lamp collected by the brightness sensor before and after the high-frequency vibration of the test sample are different, thereby completing the detection of the flexible backlight module of the laptop keyboard.

[0033] It also includes: installing the pressing platform on the push rod motor, and the pressing platform moves up and down with the operation of the push rod motor; fixing the push rod motor on the push rod motor bracket, installing the push rod motor bracket on the push rod motor bracket vibration buffer base, setting the push rod motor bracket vibration buffer base outside the rear side of the test device body, and installing the vibration motor on the pressing platform; installing the test device body 5 on the test device vibration buffer base 6, and a test result display screen 7 and a test button 8 are set on the front of the test device body 5.

[0034] Specifically, Figure 5As shown, the push rod motor bracket 1 is installed on the push rod motor bracket vibration buffer base 4 (the push rod motor bracket vibration buffer base 4 buffers the vibration generated by the vibration motor 2); the push rod motor 14 is fixedly installed on the push rod motor bracket 1, and the pressing platform 3 is installed on the push rod motor 14, and the pressing platform 3 can move up and down with the operation of the push rod motor 14; the vibration motor 2 is installed on the pressing platform 3. The test device body 5 is installed on the test device vibration buffer base 6, and the test device vibration buffer base 6 buffers the vibration of the vibration motor transmitted to the test device body 5 through the pressing platform 3; (the above structure is a setting to control the vibration motor to move in contact with the test sample on the test device body, which can ensure that the vibration motor vibrates the test sample and ultimately ensures the normal operation of the test).

[0035] like Figure 5 As shown, the test result display screen 7 and the test button 8 are arranged on the front panel of the test device body 5. (The operator can set the entire test through the test button, and the test result display screen can also conveniently display the final test result; at the same time, the test result display screen and the test button are arranged on the front panel of the test device body, which is convenient for the operator to operate, and the display result is also very convenient and clear)

[0036] like Figure 5 As shown, the test device body 5 is also provided with a downward pressure platform guide column 10. The downward pressure platform moves up and down with the operation of the push rod motor, which means that the downward pressure platform moves up and down along the downward pressure platform guide column with the operation of the push rod motor. (The downward pressure platform guide column can ensure the direction of the downward pressure platform movement)

[0037] After the step of determining whether the test sample has cold soldering or false soldering by judging whether the data of the RGB-LED lamp collected by the brightness sensor before and after the high-frequency vibration of the test sample are different, the data processing unit further includes: after the test result display displays the test result, the push rod motor controls the downward pressure platform to rise, and the flap flips and leaves the upper plane of the test device body, and the test sample of the laptop computer keyboard flexible backlight module is taken out to complete the detection of the laptop computer keyboard flexible backlight module.

[0038] The data processing unit determines whether the test sample has a cold solder joint or a false solder joint by judging whether the data of the RGB-LED lamp collected by the brightness sensor before and after the high-frequency vibration of the test sample are different. Specifically, if the test sample has a cold solder joint or a false solder joint, when it is vibrated, the brightness of the RGB-LED lamp will fluctuate due to the unstable contact state of the components on the test sample, and the brightness sensor will capture this situation. According to whether the data of the RGB-LED lamp collected by the brightness sensor before and after the high-frequency vibration of the test sample are different, it is determined whether the test sample has a cold solder joint or a false solder joint.

[0039] The data processing unit, the push rod motor, the vibration motor, the test device body, the test result display, the test button, the brightness sensor, the brightness sensor circuit board, the test sample power supply spring, the test sample gold finger 12, and the test sample RGB-LED lamp are electrically connected. (The above electrical connection setting forms a loop, and the data of the RGB-LED lamp collected by the brightness sensor before and after the high-frequency vibration of the test sample are different to determine whether the test sample has a virtual solder joint or a false solder joint)
