[0036] The technical scheme in this embodiment will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0039] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those skilled in the art to implement. When the combination of technical solutions results in contradictions or is unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0040] As Figures 1-12 shown, a key knob detection device assembly includes a frame 1 and a total control center 8. The frame 1 can be composed of aluminum profiles and plates. The frame 1 includes a horizontally arranged working surface. The total control center 8 includes a host computer, a display screen and a mouse arranged on the frame 1. The display screen and the mouse are embedded in the sheet metal parts on the outer surface. The total control center 8 further includes a scanner and a main air pump arranged below the working surface for supplying air to the entire device.

[0041] Two position adjustment mechanisms are arranged on the working surface. A partition is provided in the middle part of the frame 1 to divide the whole into two workstations. The pressing detection device 2 and the rotation detection device 3 are respectively in the two workstations. There is a position adjustment mechanism in each workstation. Each position adjustment mechanism includes an X-direction driving device 51, a Y-direction driving device 52 and a Z-direction driving device 53.

[0042] The X-direction driving device 51, the Y-direction driving device 52 and the Z-direction driving device 53 all include a fixed bottom plate 54, a driving motor 55, a guide rail 56 and a lead screw nut pair controlled by the driving motor 55. The lead screw nut pair includes a nut 58 slidably connected to the guide rail 56 and a lead screw 57 fixedly connected to the output end of the driving motor 55. The driving motor 55 and the guide rail 56 are both fixed on the corresponding fixed bottom plate 54. The outer end of the nut 58 is connected to the device to be slid, so as to achieve driving. In addition, each position adjustment mechanism further includes a mounting bracket 50. The X-direction driving device 51 is arranged on the mounting bracket 50. The Z-direction driving device 53 is arranged on the X-direction driving device 51, so that the Z-direction driving device 53 is controlled by the X-direction driving device 51 to move in the X direction. The nut of the Z-direction driving device 53 is provided with the pressing detection device 2 or the rotation detection device 3, so that the pressing detection device 2 or the rotation detection device 3 is controlled by the Z-direction driving device to move in the Z direction. Thus, when the pressing detection device 2 or the rotation detection device 3 moves in the Z direction, it can move in the X direction at the same time, realizing the linkage of the X direction and the Z direction.

[0043] Furthermore, the mounting bracket 50 has a certain height, so that the pressing detection device 2 or the rotation detection device 3 is located above the test piece 4, which is convenient for pressing, touching and rotation detection.

[0044] Photoelectric sensors are provided at the upper and lower limits of the operating strokes of the X-direction driving device 51, Y-direction driving device 52, and Z-direction driving device 53. A blocking member is connected to each nut. The photoelectric sensors cooperate with the blocking members to detect whether the operation exceeds the stroke and issue a prompt to prevent the X-direction driving device 51, Y-direction driving device 52, and Z-direction driving device 53 from continuing to operate, avoiding collisions that may damage the corresponding driving components or even hit the test piece 4. In addition, cable carriers are provided on the X-direction driving device 51, Y-direction driving device 52, and Z-direction driving device 53 to protect the wires connected to each driving component.

[0045] The pressing detection device 2 includes a connecting fixing plate 23, a pressure calibration component 21 for touching and detecting the test piece 4, and a pressing component 22 for pressing and detecting the pressing function of the test piece 4. The pressure calibration component 21 and the pressing component 22 are arranged in parallel on the connecting fixing plate 23.

[0046] Among them, the pressure calibration component 21 includes a fixed seat 211 and a movable rod 212 slidably arranged on the fixed seat 211. The movable rod 212 includes a measuring round head 2121 located below the fixed seat 211, a limiting end head 2122 located above the fixed seat 211, and a sliding rod 2123 slidably connected to the fixed seat 211. The sliding rod 2123 and the fixed seat 1 are slidably connected through a bearing. The movable rod 212 is integrally in a "T" - shaped structure. The lower surface of the limiting end head 2122 contacts the fixed seat 211 to limit the sliding range of the movable rod 212 and prevent it from falling off the fixed seat 211.

[0047] There are three counterweights 213 arranged on the fixed seat 211. Each counterweight 213 slides relative to the fixed seat 211 in the vertical direction. The three counterweights 3 can be set with different weights. Their upper and lower end faces and the top surface of the movable rod 212 are all horizontal planes, and their centers of gravity are all on the central axis of the movable rod 212, so as to avoid uneven force causing the movable rod 2 to tilt. Each counterweight 213 is arranged at graded intervals in the vertical direction. The movable rod 212 can sequentially push the counterweight 213 to move. There are three groups of limiting rods 214 with different heights above the fixed seat 211. Each group includes two limiting rods 214 with the same height. Each counterweight 3 corresponds to a group of limiting rods 214, and the two limiting rods 214 in each group are located at the diagonals of the corresponding counterweight 213 to prevent the counterweight 213 from tilting. Each limiting rod 214 is fixedly connected to the fixed seat 211. Each graded counterweight 213 is slidably arranged with the limiting rod 214 at the corresponding height. The heights of the limiting rods 214 corresponding to the counterweights 213 from bottom to top increase sequentially. According to the distance that needs to be moved for each force value gear, the height of each limiting rod 214 from the fixed seat 211 is set. Each counterweight 213 is respectively placed above the corresponding limiting rod 214, so as to realize different initial heights of different counterweights 213. According to the heights of different counterweights 213, it is possible to prevent the counterweight 213 from contacting the adjacent counterweight 3 under the influence of external force, ensuring that all counterweights 3 can be sequentially contacted after being pushed by the thrust of the movable rod 2, so as to ensure that different gears of pressure can be applied to the touch switch below the movable rod 2.

[0048] The movable rod 212 is used to push the counterweight 213 to control the magnitude of the pressure acting on the touch switch. And multiple counterweights 213 are arranged and can be sequentially pushed by the movable rod 212. Without changing the gravity of the counterweight 213, different gears of pressure can be applied to the touch screen for testing. And through the distance of the movement of the movable rod 212, that is, after moving to a certain distance, the applied pressure value increases according to the gear, and there is no pressure change during this period, making the applied pressure stable. There is no need to move little by little to ensure the accuracy of the pressure, so as to improve the testing efficiency.

[0049] The pressing assembly 22 includes a driving device 221, a pressing device 223 that moves in the vertical direction by the driving device 221, and a pressure sensor 222 for detecting the pressing force of the pressing device. The driving device 221 can be a cylinder, and the output end of the cylinder can move vertically downward. The two ends of the pressure sensor 222 are respectively connected to the output end of the cylinder and the pressing device 223;

[0050] The pressing device 221 includes a fixed tube 224, the top of which is in contact with the pressure sensor, a sliding space is provided in the fixed tube 224, a limiting tube 225 and a pressing column 226 are slidably provided in the sliding space, the limiting tube 225 can be fixed in the sliding space by a top screw, the pressing column 226 is a T-shaped structure as a whole, including a sliding part and a contact part, the sliding part of the pressing column 226 slides between the top end face of the limiting tube 225 and the top side wall of the sliding space, and the contact part of the pressing column 226 passes through the limiting tube 225 and extends out from the bottom of the fixed tube 224 to contact the key switch.

[0051] The driving device 221 drives the pressing device 223 to move the touch switch downward and continue to press downward, so that the pressing column 226 slides to the top of the sliding space until the pressure sensor 222 reaches a specific pressure, thereby realizing the pressing detection of the button in the test piece 4.

[0052] The rotation detection device 3 at another workstation includes a clamp 31, a driving member 32 for controlling the clamping action of the clamp 31, and a rotating motor 33 for controlling the rotation of the clamp 31. The driving member 32 is an electric cylinder or an air cylinder. The clamping and rotating position of the clamp 31 is controlled by the electric cylinder or the air cylinder, and the rotation angle is controlled by the rotating motor 33. The rotation detection device 3 can use an electric rotating clamp. The electric rotating clamp is set on the nut in the Z-direction drive device through a mounting plate to realize the control of the electric rotating clamp, thereby realizing the rotation detection of the knob in the test piece 4.

[0053] Therefore, by setting up two workstations, the pressing detection device 2 and the rotating detection device 3 are separated, and different detections can be performed on the two products simultaneously, thereby improving the detection efficiency.

[0054] Each workstation is also provided with a light detection assembly, which includes a camera device 41 arranged on the frame 1, a pull-up door 42 arranged on the frame 1 to cooperate with the manufacture of a darkroom, and a switching device 43 for supplying power to the test piece 4. The switching device 43 is arranged in the detection tooling 7. The camera device 41 is fixed on the frame 1 and arranged above the test piece 4 to photograph the test piece 4. The camera device 41 is electrically connected to the display of the general control center 8 to photograph and display the backlight condition of the test piece 4. The pull-up door 42 can be driven by a pneumatic device, and slide rails are arranged on both sides of the pull-up door 42. The slide rails are fixedly connected to the pull-up door 42 to realize the lifting and lowering control of the pull-up door 42. After the pull-up door 42 is lowered, it forms a darkroom together with the frame 1, and the test piece 4 is covered in the darkroom. Therefore, there is no need to set up a special backlight detection darkroom. The pull-up door 42 is used to cooperate with the frame 1 to manufacture the darkroom, thereby reducing costs.

[0055] When detecting pressing or rotation, there is no need to disassemble and assemble the detection tooling 7. The Y-direction driving device is controlled to move the test piece 4 inward in the Y direction. Then, the lifting door 42 is pulled down to construct a darkroom environment, and the backlight detection can be carried out. A transfer device 43 is arranged in the detection tooling 7 to convert the electricity at the power supply of the master control center 8 into a corresponding voltage and supply it to the test piece 4 to make it emit light. The imaging device 41 is used for shooting. According to the light-emitting situation of the test piece 4 in the darkroom, it can be clearly detected whether the backlight function of the test piece 4 is perfect.

[0056] The detection tooling 7 includes a tooling bottom plate 71 and a positioning tooling 72 arranged on the tooling bottom plate 71 for fixing the test piece 4. An IC card for detecting and matching the positioning tooling 72 is arranged on the tooling bottom plate 71.

[0057] Each IC card corresponds to a detection tooling 7. After the upper computer in the master control center 8 selects the type, the IC card is scanned and only after successful matching can the test start to prevent misplacement of the detection tooling.

[0058] The pressing detection device 2 and the rotation detection device 3 are respectively arranged on the position adjustment mechanism through a quick-change structure. The quick-change structure includes a fixing plate, a pin and a screw. The fixing plate is positioned and fixed to the nut of the Z-direction driving device in the position adjustment mechanism through the pin and the screw. The screw is convenient for disassembly and installation, facilitating the disassembly, maintenance and adjustment of each detection device.

[0059] Transfer plates 81 and air valves 83 are arranged on both the pressing detection device 2 and the rotation detection device 3. The master control center 8 is respectively connected to the two transfer plates 81 and the two air valves 83 to supply power and air to the pressing detection device 2 and the rotation detection device 3. The electricity connections on the detection devices are integrated by using the transfer plates 81. The electricity on each detection device is connected to the master control center 8 through a connector. The electrical appliances on each detection device are connected or the ports are connected by unplugging and plugging the connector. Similarly, the air valves 83 centrally control the pneumatic connections on their corresponding detection devices, and the main air pump of the master control center 8 is connected to the air valves 83 to supply air.

[0060] An emergency stop button is also provided on the master control center 8 to control the entire equipment to stop working and avoid accidents such as over-limit movement of each driving component and collision.

[0061] Specifically, before testing the test piece 4, a pressure sensor is fixed on the Y-axis driving device, and the position adjustment mechanism drives the pressure sensor to move to the bottom of the pressure calibration component 21, and controls the pressure calibration component 21 to move downward, so that the measuring round head 2121 contacts the measuring plate, and continues to move downward until the movable rod 212 moves. The pressure value of the pressure sensor at this time is the force of the pressure calibration component 21 at this gear, and each time a counterweight block 213 is driven, it is recorded to obtain the force corresponding to each level of the counterweight block 213. This force is the force to push the pressure calibration component 21 at each gear. If the gear force needs to be adjusted, it can be achieved by replacing the counterweight block 213 to achieve pressure calibration of the pressure calibration component 21;

[0062] When the test piece 4 needs to be inspected, the corresponding inspection tooling 7 is selected to position and fix the test piece 4, and the main connection port of the test piece 4 is connected to the adapter 43. This can provide power to the backlight function in the test piece 4, and can transmit the feedback signals of the knobs, buttons and touch switches in the test piece 4 to the host computer of the main control center 8, so as to know whether the functions of each switch are normal during the inspection.

[0063] After the upper computer in the main control center 8 is selected, the IC card 82 on the detection tool 7 is scanned by the scanner of the main control center 8. The detection can be started only after the match is successful, which can prevent the detection tool 7 from being replaced incorrectly and thus detecting the wrong product. The detection tool 7 is then fixed to the corresponding Y-axis drive device 52.

[0064] The position adjustment mechanism is adjusted to below the pressure calibration component 21, and the X-axis drive device and the Z-axis drive device are driven to make the measuring round head 2121 contact the test piece 4 and continue to move downward until the counterweight block 213 corresponding to the required gear pressure is actuated until the touch detection of each pressure is achieved.

[0065] When the test piece 4 needs touch detection, it is adjusted to the bottom of the pressure calibration component 21 through the position adjustment mechanism, and the X-axis drive device and the Z-axis drive device are driven to make the measuring round head 2121 contact the test piece 4 and continue to move downward until the counterweight block 213 corresponding to the required gear pressure is moved, until the touch detection of each pressure is completed, it can also be moved to the bottom of the pressing column 226, and the pressing component 22 is controlled to move downward little by little until the required pressure is reached and the touch detection is completed.

[0066] When the test piece 4 needs to press the detection button, the position adjustment mechanism is controlled to move the test piece 4 to below the pressing column 226 or the measuring round head 2121, and then the pressing assembly 22 moves down until the required pressure is reached and stops, completing the pressing detection.

[0067] When the test piece 4 needs to be tested for its rotation function, switch the test fixture 7 to another working station, drive the position adjustment mechanism to move the test piece 4 below the clamping jaw 31, and then control the electric rotating clamping jaw to clamp and rotate the knob on the test piece 4 to complete the rotation test.

[0068] When the test piece 4 needs to be tested for its backlight function, control the Y-direction driving device to move the test piece 4 inward, drive the pneumatic device that controls the lifting door 42 to lower the lifting door 42 to create a darkroom environment. At this time, control the main control center 8 to supply power to make the test piece 4 emit light, start the imaging device 41 to take pictures and display them on the display screen of the main control center 8 to complete the backlight test; then raise the lifting door 42, reset the position adjustment mechanism, remove the test fixture 7, and then remove the test piece 4 to complete the test.
