Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a laptop computer testing device and a laptop computer testing method. Background Technology

[0002] Laptop testing typically includes three types of testing: keyboard key testing, keyboard backlight testing, and touchpad testing. Keyboard key testing checks if the keys are pressed correctly. Keyboard backlight testing checks if the LEDs on the keyboard illuminate clearly and completely through the transparent lettering on the keycaps. Touchpad testing checks if the touchpad's vibration function is working properly.

[0003] Currently, laptop keyboard testing typically uses three different devices to perform these three tests. This means users need to place the laptop into each of the three devices sequentially, repeating the process three times, significantly slowing down the testing process. Furthermore, this method requires three devices, taking up considerable space, and the slow transfer of the laptop between the devices also greatly impacts testing efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a laptop computer testing device and method, which greatly improves testing efficiency and reduces the footprint of the device.

[0029] Compared with the prior art, the advantages of this invention are:

[0030] 1. By setting up a first, second, third, and fourth workstation with different functions arranged around the axis, and setting up a turntable module, the fixture module can be quickly moved between multiple workstations, avoiding the need for repeated loading and unloading of materials on different testing equipment when the laptop is being tested, thus greatly speeding up the testing efficiency.

[0031] 2. By setting up a clamping module and its driving components, the laptop is automatically positioned and fixed, and automatically maintained in an unfolded state of 90° or higher, reducing manual loading time and operational difficulty.

[0032] 3. By setting pulleys, a low-friction sliding connection between the turntable and the base is achieved, reducing the drive load and equipment size.

[0033] 4. By setting up quick-release ports and quick-release adapters, the fixture module can be quickly disassembled as a whole, making it easy to transfer to other equipment for operation.

[0034] 5. By setting adjustable USB modules and their drivers, automatic and precise plugging of USB ports on laptops of different sizes is achieved, improving device compatibility.

[0035] 6. By setting up a turntable module, the automatic transfer of laptops between different testing devices is realized, which greatly improves the automation level of the laptop testing process and thus improves testing efficiency.

[0036] 7. To address the issue of differing center point positions on the fixture for laptops of different sizes, this invention precisely establishes the spatial correspondence between the camera's shooting center and the midpoint of the line connecting the center points of the two extreme laptop sizes. This fundamentally solves the problem of incomplete shooting caused by varying laptop sizes, eliminating the need for additional adjustments to the camera position or laptop placement, thus ensuring the stability and completeness of the shooting.

[0057] The following detailed, non-limiting description of the invention's technical solutions, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0058] like Figures 1 to 19 As shown, an embodiment of the present invention provides a laptop computer testing device for testing the keyboard keys, keyboard backlight, and touchpad of a laptop computer 100. The device integrates the three tests on one device via a turntable, which greatly reduces the time the laptop computer 100 spends between different testing devices and workstations, thereby improving testing efficiency and reducing the footprint of the device.

[0059] Key reference Figure 1 and Figure 2 The laptop computer testing equipment includes a base 9 and a turntable module 1 mounted on the base 9. The base 9 has four stations arranged around axis O: a first station 11, a second station 12, a third station 13, and a fourth station 14. The first station 11 is used for loading materials; the second station 12 is used for testing the buttons of the laptop computer 100; the third station 13 is used for testing the backlight of the button area of ​​the laptop computer 100; and the fourth station 14 is used for testing the vibration function of the touchpad of the laptop computer 100. The turntable module 1 drives the laptop computer 100 to rotate between the four stations, thereby achieving automated testing of the laptop computer 100. In this embodiment, the turntable module 1 drives the laptop computer 100 to rotate clockwise between the four stations sequentially, but it can also rotate counterclockwise.

[0060] For details, please refer to Figure 3The turntable module 1 is equipped with at least one clamping module 2, which is used to fix the laptop 100 and keep it in an unfolded state of 90° or more. The laptop 100 is communicatively connected to the host computer 7 for testing. In this embodiment, a total of four clamping modules 2 are provided, and a protective plate 92 is provided on the turntable module 1 to separate the four clamping modules 2. The turntable module 1 can drive the clamping modules 2 to rotate so that the clamping modules 2 can move between the first station 11, the second station 12, the third station 13, and the fourth station 14, thereby allowing the laptop 100 to be tested sequentially. Furthermore, by setting four clamping modules 2, each corresponding to one of the four stations, this application allows the four stations to work simultaneously, further improving testing efficiency.

[0061] At the first workstation 11, the operator can perform a loading operation, placing the laptop 100 on the fixture module 2, which is connected to the control module 6. After the laptop 100 is placed on the fixture module 2, the control module 6 controls the fixture module 2 to fix the laptop 100 and keep it in an unfolded state of greater than or equal to 90°. The second workstation 12 includes a pressing device 3, which is fixedly mounted on the base 9 and connected to the control module 6. The control module 6 can control the pressing device 3 to press the buttons on the laptop 100. The laptop 100 then sends a button trigger signal to the host computer 7, which determines whether the button has been triggered. The third station 13 includes a camera device 4, which is fixedly mounted on the base 9 and connected to both the host computer 7 and the control module 6. The control module 6 controls the camera device 4 to acquire images of the keypad area of ​​the laptop 100. The camera device 4 then sends the acquired images to the host computer 7, which compares the captured images with preset images to determine if the backlighting of the keypad area is normal. The fourth station 14 includes a vibration testing device 5, which is fixedly mounted on the base 9 and connected to the control module 6. The control module 6 controls the vibration testing device 5 to detect the vibration amplitude of the touchpad of the laptop 100. This application, by setting up a turntable module 1, enables the fixture module 2 to move quickly between multiple stations, avoiding the need for repeated loading and unloading of the laptop 100 on different testing equipment during different tests, thus greatly accelerating the testing efficiency.

[0062] Furthermore, since the turntable module 1 needs to rotate during operation, an electrical slip ring 8 is also provided at the center of the turntable module 1 to prevent wire tangling. The clamp control part 60 of the control module 6, such as the solenoid valve group and the switch module, is arranged around the electrical slip ring 8, and the fixed end 81 of the electrical slip ring 8 is connected to the main control part 61 of the control module 6 in the base 9, and the rotating end 82 is connected to the clamp control part 60. The main control part 61 of the control module 6, such as the PLC controller, power supply, and air supply, is located in the base 9 and is connected to the pressing device 3, the camera device 4, and the vibration testing device 5 through multiple wire holes on the first fixed plate 90. By setting the electrical slip ring 8, continuous and reliable power or fluid transmission can be achieved between the fixed components such as the power supply and air supply and the rotating components such as the control module 6, while preventing wire tangling.

[0063] Key reference Figure 4 and Figure 5 The base 9 includes a first fixing plate 90, on which a turntable hole 900 is formed. The turntable module 1 is disposed within the turntable hole 900 and slidably connected to the first fixing plate 90. Specifically, the turntable module 1 includes a hollow rotating platform 15 and a turntable 16 coaxially and fixedly connected to the rotating output end 151 of the hollow rotating platform 15. The hollow rotating platform 15 is fixedly connected to the base 9 and disposed below the first fixing plate 90, used to drive the turntable 16 to rotate around axis O. This is prior art, and the specific structure of the hollow rotating platform 15 will not be described in detail here. However, it is worth noting that in this embodiment, a side-shaft type hollow rotating platform is used for the hollow rotating platform 15. This reduces the overall vertical volume of the equipment, and because it has a central hole 150, it also facilitates the fixed end 81 of the aforementioned electrical slip ring 8 being fixedly disposed within the central hole 150. Meanwhile, a slip ring fixing hole 160 is formed on the turntable 16. The slip ring fixing hole 160 is coaxial with the center hole 150 and is used to install the rotating end 82 of the electric slip ring 8.

[0064] Furthermore, the first fixed plate 90 is provided with a plurality of pulleys 902 evenly arranged around the axis O. The turntable 16 is placed on the plurality of pulleys 902, thereby realizing the sliding connection between the turntable 16 and the first fixed plate 90 and minimizing the friction force when the turntable 16 rotates. Moreover, the first upper surface 10 of the turntable module 1 and the second upper surface 901 of the first fixed plate 90 are coplanar, which can reduce the volume of the equipment in the vertical direction and facilitate the detection of the runout error of the turntable 16 during installation, thereby greatly improving the accuracy of the equipment.

[0065] Optionally, the first fixed plate 90 is further provided with multiple first sensors 903, and the first sensors 903 are preferably slot-shaped photoelectric sensors. Multiple position detection plates 904 are provided on the turntable 16. When the turntable 16 rotates to its designated position, the first sensors 903 can detect the corresponding position detection plates 904 to determine whether the turntable 16 has rotated to the correct position, thus achieving the effect of the turntable 16 accurately rotating to the designated work position. Preferably, in this embodiment, a total of four first sensors 903 and four corresponding position detection plates 904 are provided, evenly arranged around the axis O to ensure that the turntable 16 can be detected every 90° of rotation, improving position detection accuracy.

[0066] Further reference Figure 6 The fixture module 2 is fixed to the turntable 16 by screws (not shown) and includes a first fixing mechanism 21 and a second fixing mechanism 22. The first fixing mechanism 21 is used to fix the main body 100a of the laptop 100 in the XY plane direction, wherein the buttons and touchpad are both located on the main body 100a. The second fixing mechanism 22 is used to fix the display screen 100b of the laptop 100 in a direction perpendicular to the XY plane, so as to prevent the display screen 100b from interfering with the test.

[0067] Specifically, the fixture module 2 includes a fixed base plate 23. One side of the fixed base plate 23 is fixed to the turntable 16, and the other side is used to mount the first fixing mechanism 21 and the second fixing mechanism 22. The first fixing mechanism 21 includes an X-axis drive 211, a Y-axis drive 212, and a horizontal positioning plate 210 disposed in the XY plane. The horizontal positioning plate 210 is used to place the laptop 100, and an X-axis positioning block 213 and a vertical positioning plate 214 are disposed above it. The X-axis drive 211 is used to drive the laptop 100 to move along the X-axis direction and abut against the X-axis positioning block 213, and the Y-axis drive 212 is used to drive the laptop 100 to move along the Y-axis direction and abut against the vertical positioning plate 214. This arrangement allows the laptop 100, regardless of its size, to be fixed and positioned in the XY plane with the same reference, facilitating testing.

[0068] Furthermore, refer to Figure 6 and Figure 7The horizontal positioning plate 210 is fixed above the fixed base plate 23 by at least four support columns 216, so that there is a certain installation space between the horizontal positioning plate 210 and the fixed base plate 23. The X-axis drive 211 and the Y-axis drive 212 mentioned above are both disposed in the installation space below the horizontal positioning plate 210 and are fixedly connected to the fixed base plate 23. The X-axis output end 2110 of the X-axis drive 211 is fixed with an X-axis gripper 2111. The X-axis gripper 2111 extends upward, which allows the X-axis gripper 2111 to abut against the second side 1002 of the laptop 100 when the X-axis drive 211 drives the X-axis gripper 2111 to move along the X-axis, thereby pushing the laptop 100 to move along the X-axis direction. Similarly, a Y-axis gripper 2121 is fixed to the end of the Y-axis output end 2120 of the Y-axis drive unit 212. The Y-axis gripper 2121 also extends upward. When the Y-axis drive unit 212 drives the Y-axis gripper 2121 to move along the Y-axis direction, the Y-axis gripper 2121 can abut against the first side 1001 of the laptop 100, thereby driving the laptop 100 to move along the Y-axis direction. By placing both the X-axis drive unit 211 and the Y-axis drive unit 212 in the mounting space below the horizontal positioning plate 210, the overall size of the fixture module 2 can be significantly reduced, facilitating the miniaturization design of the laptop inspection device.

[0069] Key reference Figure 8 The second fixing mechanism 22 includes a Z-axis drive component 215. The aforementioned vertical positioning plate 214 is perpendicular to the horizontal positioning plate 210. The Z-axis drive component 215 is fixedly mounted on the vertical positioning plate 214 and is used to drive the display screen 100b of the laptop 100 to move and abut against the vertical positioning plate 214. That is, the operator can fix the laptop 100 by unfolding it to a certain angle and placing it on the horizontal positioning plate 210, eliminating the need to manually adjust the opening angle of the laptop 100, reducing the operator's loading time, and thus greatly improving inspection efficiency.

[0070] More specifically, in this embodiment, the Z-axis drive 215 is a rotary cylinder, which can both retract and rotate the Z-axis output shaft 2150. Furthermore, a Z-axis gripper 2151 is fixed to the end of the Z-axis output shaft 2150. That is, the Z-axis drive 215 can drive the Z-axis gripper 2151 to rotate around the axis of the Z-axis output shaft 2150, and also drive the Z-axis gripper 2151 to move along the axis of the Z-axis output shaft 2150. This design, on the one hand, does not obstruct the placement of the laptop 100 when the operator loads materials; on the other hand, it eliminates the need for the operator to manually open the laptop 100 to 90° during loading, requiring only a certain angle, greatly reducing loading time and difficulty, and improving inspection efficiency.

[0071] Preferably, the X-axis drive unit 211 and Y-axis drive unit 212 are both cylinders, and each of the X-axis gripper 2111, Y-axis gripper 2121, and Z-axis gripper 2151 is provided with a flexible member 24, the shape of which matches the corresponding gripper, to avoid damage to the laptop computer 100 when the grippers contact the laptop computer 100. Preferably, the flexible member 24 is made of rubber.

[0072] Furthermore, to improve the stability of the laptop 100 during movement, at least two of the aforementioned X-axis grippers 2111, Y-axis grippers 2121, and Z-axis grippers 2151 are provided. Since the second side 1002 of the laptop 100 is narrower, only one X-axis drive unit 211 is provided. Both X-axis grippers 2111 are fixed to the X-axis output end 2110 and driven by a single X-axis drive unit 211. However, the first side 1001 of the laptop 100 is wider, therefore two Y-axis drives 212 and two Z-axis drives 215 are provided to drive the corresponding grippers.

[0073] Further reference Figure 9 The clamp module 2 also includes a USB module 25 for connecting the laptop 100 and the host computer 7. The USB module 25 includes a plug driver 240, and the plug output terminal 2401 of the plug driver 240 is provided with a USB plug 241 that is electrically connected to the host computer 7. The plug driver 240 can drive the USB plug 241 to move along the Y-axis direction so as to plug into the USB interface on the laptop 100. Furthermore, since different laptops 100 have different thicknesses and sizes, the USB interface is positioned differently in the Z-axis and Y-axis directions. Therefore, the USB module 25 also includes an adjustment driver 242. The adjustment driver 242 is fixed on the fixed base plate 23 and is tilted. More specifically, the adjustment driver 242 is set in the YZ plane and tilted at 45° with the Y-axis. The plug driver 240 is fixed on the output end of the adjustment driver 242, so that the adjustment driver 242 can drive the USB plug 241 to move in the Y-axis and Z-axis directions, thus making it suitable for different laptops 100 and improving the applicability of the device.

[0074] Optionally, different laptops 100 have different sizes. To detect the size of the laptop 100 placed on the clamp module 2 for the USB module 25 to be plugged in, a second sensor 251, a third sensor 252, and a fourth sensor 253 are provided on the horizontal positioning plate 210. Generally, laptops 100 are divided into 13-inch laptops and 15-inch laptops. When the laptop 100 is placed on the horizontal positioning plate 210, it covers the second sensor 251 and the third sensor 252, while the fourth sensor 253 cannot detect the object. In this case, the laptop 100 is determined to be a 13-inch laptop. When the laptop 100 is placed on the horizontal positioning plate 210, it covers the second sensor 251, the third sensor 252, and the fourth sensor 253. In this case, the laptop 100 is determined to be a 15-inch laptop. By setting the second sensor 251, the third sensor 252, and the fourth sensor 253 in different positions, the type of laptop 100 is determined simply and reliably, and at a low cost.

[0075] In addition, to avoid interference between the second sensor 251, the third sensor 252 and the fourth sensor 253 and the laptop 100, a clearance groove 255 is provided at the corresponding position of the horizontal positioning plate 210. The second sensor 251, the third sensor 252 and the fourth sensor 253 are respectively set in the corresponding clearance groove 255 and do not protrude from the surface of the horizontal positioning plate 210.

[0076] Similarly, in order to detect whether the laptop 100 is opened at 90°, a fifth sensor 254 is provided on the vertical positioning plate 214 to detect whether the display screen 100b of the laptop 100 has moved into place, and an avoidance groove 255 is also provided at the corresponding position of the vertical positioning plate 214 to accommodate the fifth sensor 254 and avoid interfering with the display screen 100b.

[0077] Furthermore, to prevent wear and tear on the laptop 100 during the positioning and fixing process, protective components 26 are provided on both the horizontal positioning plate 210 and the vertical positioning plate 214. In particular, a protective component receiving groove 243 is formed on the horizontal positioning plate 210 for installing the protective component 26.

[0078] Furthermore, we will focus on referring to Figure 10The fixed base plate 23 is also provided with a quick-release adapter 271, and the turntable 16 is provided with a corresponding quick-release socket 270. One end of the quick-release socket 270 is connected to the control module 6 through a pipeline, more specifically, to the solenoid valve group in the control module 6 through a pipeline, and the other end of the quick-release socket 270 is detachably connected to the quick-release adapter 271. The quick-release adapter 271 is connected to the aforementioned X-axis drive 211, Y-axis drive 212, Z-axis drive 215, plug-in drive 240, and adjustment drive 242 through pipelines. It is known that when the quick-release adapter 271 is connected to the quick-release socket 270, the control module 6 can be connected to the X-axis drive 211, Y-axis drive 212, Z-axis drive 215, plug-in drive 240, and adjustment drive 242 through pipelines, enabling the control module 6 to control the movement of the X-axis drive 211, Y-axis drive 212, Z-axis drive 215, plug-in drive 240, and adjustment drive 242. The quick-release adapter 271 is composed of multiple pneumatic quick-connectors arranged evenly, while the quick-release socket 270 is composed of corresponding pneumatic quick-connectors. When the user needs to perform other tests or operations on the laptop 100, the entire fixture module 2 can be removed from the device and quickly placed on other devices for operation, reducing the need for repositioning and fixing the laptop 100. Only the same quick-release socket 270 needs to be set on other devices to control the multiple drives on the fixture module 2.

[0079] Key reference Figure 11 and Figure 12 The pressing device 3 includes an ejector drive 30 and a pressing mechanism 31. The pressing mechanism 31 includes a plurality of pressing units 310. The ejector drive 30 is used to drive the pressing mechanism 31 to move above the clamp module 2, more precisely, to move above the main body 100a of the laptop 100. The pressing units 310 are used to press the buttons on the main body 100a of the laptop 100 in the vertical direction. Specifically, the pressing device 3 includes a first fixing member 32, and the pressing mechanism 31 is slidably mounted on the first fixing member 32 via a pair of parallel first guide rail slider assemblies 33. The push-out drive member 30 is mounted on the side of the pressing mechanism 31 and fixed to the first fixing member 32. The output end of the push-out drive member 30 is fixedly connected to the pressing mechanism 31, so that the push-out drive member 30 can drive the pressing mechanism 31 to move along the arrangement direction of the first guide rail slider assembly 33. This allows the pressing mechanism 31 to move above the laptop 100 for testing during keyboard key testing, and to retract after testing to avoid affecting the laptop 100's rotation to the next station.

[0080] Furthermore, since the button positions of different sized laptops 100 are also different, the pressing device 3 is specially designed to test laptops 100 of different sizes. Specifically, the pressing mechanism 31 includes a first adjusting plate 311, a second adjusting plate 312, and an oblique driving member 313. The first adjusting plate 311 is connected to the output end of the first guide rail slider assembly 33 and the push-out driving member 30. The second adjusting plate 312 is mounted on the first adjusting plate 311 via the second guide rail slider assembly 314. The oblique driving member 313 is also fixedly mounted on the first adjusting plate 311, and its output end is connected to the second adjusting plate 312. This allows the oblique driving member 313 to drive the second adjusting plate 312 to move along the arrangement direction of the second guide rail slider assembly 314, thereby adjusting the position of the second adjusting plate 312 in the XY plane. The second adjusting plate 312 is provided with multiple fixing holes 3120, and the pressing unit 310 is disposed in the corresponding fixing holes 3120. This ultimately enables the pressing unit 310 to move between different positions in the XY plane, thus adapting to different laptops 100.

[0081] Optionally, the first fixing member 32 is provided with at least one first limiting member 341. When the push-out driving member 30 drives the first adjusting plate 311 to move to the limit position, the first limiting member 341 abuts against the first adjusting plate 311 to provide a buffering effect and prevent damage to the equipment. Similarly, the first adjusting plate 311 is provided with at least one second limiting member 342. When the oblique driving member 313 drives the second adjusting plate 312 to move to the limit position, the second limiting member 342 abuts against the second adjusting plate 312 to provide a buffering effect.

[0082] Furthermore, the pressing unit 310 includes a pressing cylinder 35 and a pressing head 36. The pressing cylinder 35 is fixedly mounted on the second adjustment plate 312 along the Z-axis direction, and the pressing output shaft 350 of the pressing cylinder 35 passes through the fixing hole 3120 and is fixedly connected to the pressing head 36. The pressing cylinder 35 can drive the pressing head 36 to move along the Z-axis direction, thereby enabling the pressing head 36 to press on the key of the laptop computer 100.

[0083] Key reference Figure 13 and Figure 14 The press head 36 includes a connecting block 360, an elastic head 361, and an elastic element 362. One end of the connecting block 360 is fixedly connected to the aforementioned press output shaft 350, and the other end forms an elastic groove 364. The elastic head 361 is at least partially slidably disposed within the elastic groove 364. The elastic element 362 is disposed within the elastic groove 364, with one end abutting against the bottom wall forming the elastic groove 364 and the other end abutting against the elastic head 361. When the press head 36 contacts the button, the elastic head 361 can overcome the elastic action of the elastic element 362 to achieve a buffering effect, thereby preventing damage to the button.

[0084] In detail, one end of the connecting block 360 has at least two connecting pieces 3601. The press output shaft 350 is engaged within the space enclosed by the connecting pieces 3601. A retaining ring 3602 is fitted over the connecting pieces 3601. The retaining ring 3602 has a U-shaped opening, and a locking screw 3603 is provided at the opening. Tightening the locking screw 3603 increases the pressure of the retaining ring 3602 on the connecting pieces 3601, thereby fixing the press output shaft 350 between the multiple connecting pieces 3601, thus securing the press output shaft 350 to the connecting block 360. The aforementioned elastic head 361 includes interconnected elastic parts 3610 and connecting members 3611. The connecting member 3611 is slidably disposed within the elastic groove 364. The elastic part 3610 is made of a flexible material and is used to contact the button, preventing damage to the button.

[0085] In addition, to prevent the elastic head 361 from moving out of the elastic groove 364, a sliding groove 365 is provided on the side wall of the elastic groove 364. The sliding groove 365 extends along the Z-axis direction. The pressing head 36 also includes a limiting rod 366. The limiting rod 366 passes through the connector 3611 and is at least partially disposed in the sliding groove 365. The limiting rod 366 can move along the arrangement direction of the sliding groove 365, so that the elastic head 361 always moves within the elastic groove 364 and will not come out, thus avoiding damage to the laptop 100.

[0086] Furthermore, two symmetrical sliding grooves 365 are provided on the side wall forming the elastic groove 364. The middle part of the limiting rod 366 passes through the connector 3611, and the two ends are respectively set in the two sliding grooves 365 to improve the stability of the elastic head 361 during movement.

[0087] Furthermore, we will focus on referring to Figure 15 The camera device 4 includes a second fixing member 40 and a camera 41. The second fixing member 40 is fixedly connected to the base 9, and the camera 41 is fixed to the end of the second fixing member 40 away from the base 9 to ensure that the camera's field of view can encompass the entire fixture module 2. Specifically, the second fixing member 40 includes a gantry frame 401 and a pair of connecting fixing plates 402. One end of the gantry frame 401 is fixedly mounted on the base 9, and the other end is fixed to the connecting fixing plate 402. The camera 41 is fixedly mounted between the pair of connecting fixing plates 402.

[0088] It is worth noting that, in order to ensure that laptops 100 of different sizes can be photographed completely, this application also innovatively sets the position of the camera 41. (See reference...) Figure 16The center point of the laptop 100 of different sizes is located at different positions on the clamping module 2. When the laptop 100 is at its smallest size, its center point is located at the first midpoint D on the clamping module 2. When the laptop 100 is at its largest size, its center point is located at the second midpoint D′ on the clamping module 2. In this embodiment, the laptop 100 has a minimum size of 13 inches and a maximum size of 15 inches. The camera 41 has a shooting center. The line connecting the first midpoint D of the 13-inch laptop 100 and the second midpoint D′ of the 15-inch laptop 100 has a third midpoint D”. In the Z-axis direction, the shooting center of the camera 41 overlaps with the third midpoint D”, thereby ensuring that laptops 100 of different sizes can be completely photographed. This application addresses the issue of differing center point positions of laptops 100 of different sizes on the fixture. By precisely locating the spatial correspondence between the shooting center of the camera 41 and the midpoint of the line connecting the center points of the two extreme-sized laptops 100, it solves the problem of incomplete shooting caused by the different sizes of the laptops 100 at the root of the shooting perspective. It ensures the stability and integrity of the shooting without the need for additional adjustments to the position of the camera 41 or the placement of the laptops 100.

[0089] Optionally, since a dark environment is required during shooting, the base 9 also includes a protective cover assembly 91. The protective cover assembly 91 covers the first fixed plate 90, and the first station 11 is located outside the protective cover assembly 91, while the second station 12, the third station 13, and the fourth station 14 are all located inside the protective cover assembly 91. The protective cover assembly 91 is fitted with a protective plate 92 on the turntable 16 to separate the different stations, and an elastic light-shielding strip is provided at the mating point between the protective cover assembly 91 and the protective plate 92, thereby ensuring a dark environment inside the equipment and preventing the protective cover assembly 91 from affecting the rotation of the turntable 16, thus improving the accuracy of the detection.

[0090] Further reference Figure 17 and Figure 18 The touchpad contains a vibration source. The vibration testing device 5 includes a vertical drive 52, a fixing device 50, and an acceleration sensor 51. The vertical drive 52 can drive the fixing device 50 to move vertically, causing the bottom of the fixing device 50 to contact and adhere to the touchpad. The acceleration sensor 51 is fixedly installed inside the fixing device 50 and is configured to detect the vibration amplitude of the vibration source. This is prior art; for details, please refer to patent CN118225224B, which will not be elaborated upon here.

[0091] In addition, to prevent the turntable 16 from starting during material feeding, a safety light curtain 910 is also provided on the protective cover assembly 91. The safety light curtain 910 is located at the first station 11 and is used to detect whether the first station 11 is feeding material, so as to improve the safety of the equipment.

[0092] Finally, this application also provides a method for testing a laptop computer using the aforementioned laptop computer testing device, which includes the following steps:

[0093] Turn on the laptop inspection equipment and have the laptop 100 placed on the fixture module 2 by a person or machine at the first station 11;

[0094] Start the laptop testing device and establish a communication connection between the laptop 100 and the host computer 7;

[0095] The control module 6 controls the clamp module 2 to fix the laptop 100 and keep the laptop 100 in an unfolded state of greater than or equal to 90°.

[0096] It is worth noting that in this embodiment, the clamp module 2 first positions the laptop 100, detects the size of the laptop 100, and then the USB module 25 is plugged into the laptop 100 to connect the laptop 100 to the host computer 7. This allows for automated fixing and connection of laptops 100 of different sizes.

[0097] Next, the control module 6 controls the turntable module 1 to work, thereby driving the fixture module 2 to rotate so that the fixture module 2 moves to the second station 12. The control module 6 controls the pressing device 3 to press the button on the host unit 100a of the laptop 100. The laptop 100 sends the trigger signal of the button to the host computer 7. The host computer 7 determines whether the button is qualified based on the trigger signal.

[0098] Then, control module 6 controls turntable module 1 to operate, thereby driving fixture module 2 to rotate so that fixture module 2 moves to the third station 13. Control module 6 controls camera device 4 to capture images of the key area of ​​laptop 100 and sends them to host computer 7. Host computer 7 compares the images of the key area with preset images to determine whether the backlight of the key area of ​​laptop 100 is qualified. More specifically, the image acquired in this step is an image of the main unit 100a of laptop 100.

[0099] Next, the control module 6 controls the turntable module 1 to work, thereby driving the fixture module 2 to rotate so that the fixture module 2 moves to the fourth station 14. The control module 6 controls the vibration testing device 5 to work to test the vibration amplitude of the touchpad of the laptop 100.

[0100] Finally, the control module 6 controls the turntable module 1 to work, thereby driving the clamp module 2 to rotate so that the clamp module 2 moves back to the first station 11. The control module 6 controls the clamp module 2 to reset, so as to unfix the laptop 100 and remove the laptop 100 manually or by machine.

[0101] It is worth noting that the test content of the second station 12, the third station 13 and the fourth station 14 can be changed by setting the rotation direction of the turntable 16. Furthermore, the test devices on each station, such as the pressing device 3, the camera device 4 and the vibration test device 5, are all modularly designed, enabling quick replacement to meet customer needs and facilitate maintenance.

[0102] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
