Description

Technical Field

[0001] This invention relates to the field of testing device technology, and in particular to a notebook keyboard key sensitivity testing device and its testing method. Background Technology

[0002] In the laptop assembly line, keyboard key testing is a major quality inspection item in the final inspection of finished products. The testing cycle must be matched with the upstream line speed to avoid laptops piling up and affecting the overall line capacity.

[0003] Currently, the upstream line speed can achieve a material output cycle time of 12 seconds, while the shortest test time for a single laptop's complete button function (including feeding, discharging, and testing) is 14 seconds. If conventional single-station testing equipment is used, the overall testing cycle time is slower than the upstream material output line speed, making online synchronous testing impossible. This can easily lead to material accumulation on the production line, requiring additional buffer stations, which would occupy production space and reduce production efficiency.

[0004] Therefore, it is necessary to improve the existing notebook keyboard key sensitivity testing devices. Summary of the Invention

The pressure detection mechanism is also provided with a pressing buffer assembly for buffering.

[0012] A preferred technical solution is that the pressing buffer assembly includes a mounting plate and a pressure plate fixedly connected to the mounting plate, a support plate slidably connected to the mounting plate, the sliding direction of the support plate being vertically set, and an elastic element sandwiched between the support plate and the pressure plate.

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0020] like Figure 1-10 As shown, the notebook keyboard key sensitivity testing device of this embodiment includes a frame 100, a transmission component 200 connected to the frame 100, and a detection component 300. The transmission component 200 includes a feeding transmission mechanism 700, two sets of parallel transmission units, and a discharging transmission mechanism 800. The transmission units include a lifting belt assembly and a translation belt assembly. The conveying direction of the belt is a first direction, and the sliding direction of the translation belt assembly is perpendicular to the first direction. The two sets of transmission units cooperate to input, test, detect, and output the notebook. It also includes two detection stations, each corresponding to one of the two translation belt assemblies. A main drive component 400 is provided between the detection component 300 and the frame 100 for driving the detection component 300 to switch between the two detection stations. The main drive component 400 is also used to drive the detection component 300 to move and lift between the notebook keycaps.

[0021] Specifically, two sets of transmission units are arranged side by side, each set integrating a lifting belt assembly and a translation belt assembly. The transmission assembly 200 conveys the notebook along the first direction, realizing the forward and backward flow of feeding and discharging; the translation belt assembly can slide laterally along the direction perpendicular to the conveying direction, driving the notebook to switch between the detection position and the flow position. The lifting belt assembly and the translation belt assembly work together to complete the notebook's input, inspection, detection, and output process.

[0022] When operating in alternating dual-station mode, one station performs testing while the other simultaneously completes loading and unloading, effectively reducing waiting time, increasing output per unit time, and adapting to the high-speed discharge rhythm upstream. Specifically, the main drive component 400 can adopt a common three-axis drive device.

[0023] like Figure 6As shown, in another preferred embodiment, the transmission component 200 includes a first lifting belt assembly 210, a first translating belt assembly 220, a second lifting belt assembly 230, and a second translating belt assembly 240. The first lifting belt assembly 210 includes a first station 211 and a second station 212. The first translating belt assembly 220 includes a third station 221 and a fourth station 222. The second lifting belt assembly 230 includes a fifth station 231 and a sixth station 232. The second translating belt assembly 240 includes a seventh station 241 and an eighth station 242. The first station 211 and the third station 221 are arranged to overlap, and the fifth station 231 and the seventh station 241 are arranged to overlap. The two detection stations correspond to the fourth station 222 and the eighth station 242, respectively. The first station 211 and the seventh station 241 cooperate to transmit the laptop, and the third station 221 and the fifth station 231 cooperate to transmit the laptop.

[0024] Specifically, the transmission component 200 consists of four sets of belt units with clearly defined functions. Two sets of lifting belt units are responsible for the forward and backward transfer of the laptops along the conveying direction, while two sets of translational belt units are responsible for the lateral repositioning along the direction perpendicular to the conveying direction and cooperate with the lifting belt units to transfer the laptops. They also serve as the main support for the inspection station. The four sets of belt units divide the work into eight work stations, and the seamless transfer of laptops is achieved through the overlapping and docking design of the work stations.

[0025] The first station 211 overlaps with the third station 221, forming a notebook transfer station on the feeding side; the fifth station 231 overlaps with the seventh station 241, forming a notebook transfer station on the discharging side. The first lifting belt assembly 210 can move up and down between the first station 211 and the second station 212, and the second lifting belt assembly 230 can move up and down between the fifth station 231 and the sixth station 232. In conjunction with the two sets of translation belts changing positions between corresponding stations, the entire process of notebook feeding, waiting, inspection, and discharging is completed.

[0026] Specifically, the movement of the first lifting belt assembly 210, the first translation belt assembly 220, the second lifting belt assembly 230, and the second translation belt assembly 240 can be driven by a common motor-screw combination.

[0027] like Figure 7 As shown, in another preferred embodiment, the detection component 300 includes a substrate 310 and two independently arranged pressing units connected to the substrate 310. The two pressing units are arranged side by side along a first direction, and the two pressing units correspond to the left and right parts of the keyboard respectively.

[0028] Specifically, two sets of pressing units are independently mounted on the base plate 310 and arranged side by side along the first direction of the belt conveyor. During operation, they correspond to the left and right half of the keyboard respectively. The two sets of independent pressing units are detected simultaneously to improve detection efficiency and reduce the detection time of a single keyboard.

[0029] like Figure 7 As shown, in another preferred embodiment, the pressing unit includes two sets of translational pressing components 320 and a middle pressing component 330. The two sets of translational pressing components 320 are respectively disposed on both sides of the middle pressing component 330. The arrangement direction of the translational pressing components 320 and the middle pressing component 330 is perpendicular to the first direction. The translational pressing components 320 are slidably connected to the substrate 310. The sliding direction of the translational pressing components 320 is perpendicular to the first direction. A translational driving component 340 for driving the translational pressing components 320 to slide is disposed between the translational pressing components 320 and the substrate 310.

[0030] The pressing unit adopts a modular arrangement with a fixed center and adjustable sides. Two sets of translational pressing components 320 are respectively located on both sides of the central pressing component 330, and the arrangement direction of the three is perpendicular to the belt conveyor direction. The central pressing component 330 is a fixed installation structure, corresponding to the standard key row of the main key area of ​​the keyboard: the spacing between the second to fifth rows of the keyboard is constant; the translational pressing components 320 on both sides are slidably connected to the base plate 310 through linear guides, and can slide independently in the lateral direction under the drive of the translational drive component 340, thereby adjusting the spacing with the central pressing component 330 to adapt to the key spacing of the first and sixth rows of different keyboards: for example, the arrow keys of Lenovo laptops have different spacing than other keyboards.

[0031] Specifically, the translation drive component 340 can use a common motor-screw combination to drive the movement of the translation pressing component 320.

[0032] like Figure 9 As shown, in another preferred embodiment, each group of translational pressing components 320 is provided with a pressure detection mechanism 500, and the middle pressing component 330 is provided with four groups of pressure detection mechanisms 500 side by side. The pressure detection mechanisms 500 are slidably disposed, and the sliding direction of the pressure detection mechanisms 500 is parallel to the first direction. Each group of pressure detection mechanisms 500 is provided with a displacement driving component 510 for driving its sliding.

[0033] During the testing operation, the displacement drive assembly 510 drives each pressure detection mechanism 500 to move sequentially along the first direction, coordinating with the vertical pressing action to simultaneously complete the testing of the six rows of buttons. Specifically, the displacement drive assembly 510 can use a common motor-screw combination to drive the movement of the pressure detection mechanism 500.

[0034] like Figure 10As shown, in another preferred embodiment, the pressure detection mechanism 500 includes a support plate 521, a pressing head 522, and a pressure sensor 523 sandwiched between the support plate 521 and the pressing head 522. The pressure detection mechanism 500 is also provided with a pressing buffer assembly for cushioning.

[0035] The pressure detection mechanism 500 is based on the support plate 521, with a pressing head 522 at its lower end that directly contacts the keyboard keycaps. A pressure sensor 523 is fixed between the support plate 521 and the pressing head 522. The force generated by the pressing action can be directly transmitted to the sensor, providing real-time feedback on the force changes during key pressing. The pressure sensor 523 can be a Spartacus SBT671 tension / compression sensor.

[0036] The press-down buffer provides a flexible travel margin for the pressing action. During the pressing process, the initial impact force is first absorbed by the buffer structure, and then the pressing force is gradually transmitted to the button surface, simulating the gentle force application process of manual pressing.

[0037] like Figure 10 As shown, in another preferred embodiment, the pressing buffer assembly includes a mounting plate 524, a pressure plate 525 fixedly connected to the mounting plate 524, a support plate 521 slidably connected to the mounting plate 524, the sliding direction of the support plate 521 being vertically arranged, and an elastic element 526 sandwiched between the support plate 521 and the pressure plate 525.

[0038] During operation, the main drive assembly 400 drives the overall detection unit downward. After the pressing head 522 contacts the keycap, it receives a reaction force, pushing the support plate 521 to slide upward along the guide structure. Simultaneously, it compresses the elastic element 526, converting the rigid downward force into an elastic pressure state, making the key's force application process smooth and simulating the rhythm of manual pressing. Specifically, the elastic element 526 can be a common structure such as a compression spring.

[0039] like Figure 8 As shown, in another preferred embodiment, the detection component 300 further includes a visual positioning component 600, which is connected to the substrate 310 and is disposed on the side between the two sets of pressing units. The visual positioning component 600 includes a camera 610 and a ring light source 620 disposed below the camera 610, with the camera 610 and the ring light source 620 coaxially arranged.

[0040] Specifically, the visual positioning component 600 adopts a coaxial arrangement of camera 610 and ring light source 620. The ring light source 620 is located directly below the lens of camera 610, which can project uniform ring light onto the keyboard surface, effectively reducing the reflection and shadow on the keycap surface, and making the key characters and outline edges clear.

[0041] During operation, the vision positioning component 600 can move synchronously with the detection module. When changing detection stations, it can identify the reference features on the keyboard surface and automatically correct the coordinates of the pressing unit, reducing the workload of manual debugging.

[0042] like Figure 2 As shown, in another preferred embodiment, a feeding conveyor mechanism 700 is also provided on the feeding side of the frame 100. The feeding conveyor mechanism 700 includes a feeding belt assembly 710 and a guide plate 720 provided on the feeding side of the feeding belt assembly 710. The two guide plates 720 are flared, and rollers 721 are rotatably provided on the opposite surfaces of the two guide plates 720.

[0043] Specifically, two guide plates 720 are respectively located on both sides of the feed end of the feed belt assembly 710, and are in the shape of a wide inlet and a narrow outlet. When there is a positional deviation of the incoming material, the widened structure can gradually close the notebook position along the conveying direction and automatically complete the correction.

[0044] Several freely rotatable rollers 721 are arranged on the relatively inner side of the guide plate 720 along the conveying direction. The wheel surface of the rollers 721 protrudes from the inner wall of the guide plate 720. When the side of the notebook contacts the guide plate 720, it directly contacts the rollers 721, converting sliding friction into rolling friction. This can reduce conveying resistance, improve the smoothness of notebook flow, and also prevent the hard surface of the guide plate 720 from scratching the side of the notebook casing, thus protecting the appearance quality of the notebook.

[0045] Specifically, the feeding conveyor 700 and the discharging conveyor 800 can be equipped with common belt conveyor devices.

[0046] This invention also provides a method for testing the sensitivity of a laptop keyboard keys, comprising the following steps: S1. Initial state: The first lifting belt assembly 210 is located at the first station 211, the first translation belt assembly 220 is located at the fourth station 222, the second lifting belt assembly 230 is located at the sixth station 232, and the second translation belt assembly 240 is located at the eighth station 242. There are laptops on both the first translation belt assembly 220 and the second translation belt assembly 240. S2. The main drive component 400 moves the detection component 300 above the eighth station 242, aligns the middle pressing component 330 with the middle four rows of keyboards, the translation drive component 340 drives the translation pressing component 320 to correspond to the first row of keyboards and the sixth row of keyboards respectively, the displacement drive component 510 drives the pressure detection mechanism 500 to the top of the keycaps, and the main drive component 400 drives the detection component 300 to descend to perform key sensitivity testing. S3, the displacement drive component 510 drives the pressure detection mechanism 500 to move one by one between each keycap, and the main drive component 400 drives the detection component 300 to descend and test in sequence until all keys of the current laptop have been tested. S4. The main drive component 400 moves the detection component 300 above the fourth station 222 to perform key testing on the laptop on the first translation belt component 220. S5. The second translation belt assembly 240 moves from the eighth station 242 to the seventh station 241, and the second translation belt assembly 240 outputs the tested notebook. S6. The laptop under test is transferred from the feed side to the second translation belt assembly 240 via the first lifting belt assembly 210. Then the second translation belt assembly 240 moves from the seventh station 241 to the eighth station 242 to wait for testing. S7. The first lifting belt assembly 210 moves from the first station 211 to the second station 212, and the second lifting belt assembly 230 moves from the sixth station 232 to the fifth station 231. The laptop that has been inspected at the fourth station 222 is moved from the fourth station 222 to the third station 221 via the first translation belt assembly 220. The laptop that has been inspected is output sequentially via the first translation belt assembly 220 and the second lifting belt assembly 230. S8. The laptop to be tested is transferred from the feed side to the first translation belt assembly 220. The first translation belt assembly 220 moves from the third station 221 to the fourth station 222 for testing. The first lifting belt assembly 210 moves from the second station 212 to the first station 211. The second lifting belt assembly 230 moves from the fifth station 231 to the sixth station 232. S9. Repeat steps S2-S8 until all laptop tests are completed.

[0047] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

The first station (211) is arranged to overlap with the third station (221), and the fifth station (231) is arranged to overlap with the seventh station (241). The two detection stations correspond to the fourth station (222) and the eighth station (242) respectively. The first station (211) and the seventh station (241) cooperate to transmit the laptop, and the third station (221) and the fifth station (231) cooperate to transmit the laptop. Including the following steps: S1. Initial state: The first lifting belt assembly (210) is located at the first station (211), the first translation belt assembly (220) is located at the fourth station (222), the second lifting belt assembly (230) is located at the sixth station (232), and the second translation belt assembly (240) is located at the eighth station (242). Both the first translation belt assembly (220) and the second translation belt assembly (240) have laptops on them. S2, the main drive component (400) moves the detection component (300) above the eighth station (242), aligns the middle pressing component (330) with the middle four rows of keyboards, the translation drive component (340) drives the translation pressing component (320) to correspond to the first row of keyboards and the sixth row of keyboards respectively, the displacement drive component (510) drives the pressure detection mechanism (500) to the top of the keycaps, and the main drive component (400) drives the detection component (300) to descend to perform key sensitivity testing; S3, the displacement drive component (510) drives the pressure detection mechanism (500) to move one by one between each keycap, and the main drive component (400) drives the detection component (300) to descend and test in sequence until all keys of the current laptop have been tested. S4. The main drive assembly (400) moves the detection assembly (300) above the fourth station (222) to perform key testing on the notebook on the first translation belt assembly (220); S5, the second translation belt assembly (240) moves from the eighth station (242) to the seventh station (241), and the second translation belt assembly (240) outputs the tested notebook; S6. The notebook under test is transferred from the feed side to the second translation belt assembly (240) via the first lifting belt assembly (210). Then the second translation belt assembly (240) moves from the seventh station (241) to the eighth station (242) to wait for testing. S7. The first lifting belt assembly (210) moves from the first station (211) to the second station (212), and the second lifting belt assembly (230) moves from the sixth station (232) to the fifth station (231). The laptop that has been inspected at the fourth station (222) is moved from the fourth station (222) to the third station (221) by the first translation belt assembly (220). The laptop that has been inspected is output sequentially by the first translation belt assembly (220) and the second lifting belt assembly (230). S8. The notebook under test is transferred from the feed side to the first translation belt assembly (220). The first translation belt assembly (220) moves from the third station (221) to the fourth station (222) for testing. The first lifting belt assembly (210) moves from the second station (212) to the first station (211). The second lifting belt assembly (230) moves from the fifth station (231) to the sixth station (232). S9. Repeat steps S2-S8 until all laptop tests are completed.
