Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to an automatic switch testing device. Background Technology

[0002] The entire switch testing process in the factory usually requires two people to work together: one to test the screen and buttons, and the other to test the shielding box. If production increases, more manpower and tooling are needed. Manual testing is inefficient and has high labor costs.

[0003] The specific operating procedure is as follows:

[0004] 1. Test screen

[0005] Workers use simple fixtures to secure the switch. The fixtures have probes that contact the switch's contacts to supply power. After power is applied, the high-voltage switch on the switch is pressed, and the screen is checked for complete display and any defects.

[0006] 2. Test button

[0007] If the screen is working properly, the worker presses the buttons on the switch in sequence and checks whether the light bulb next to it lights up to determine if the buttons are working.

[0008] 3. Test inside the shielded enclosure

[0009] Products that pass the first two processes are handed over to another worker to be placed in a shielded box for testing.

[0010] The entire testing process takes an average of 60 seconds. During this time, factors such as staff fatigue can reduce efficiency and make it impossible to guarantee the consistency of the testing environment.

[0011] Therefore, how to provide an automatic switching test device that can effectively improve testing efficiency is one of the technical problems that needs to be solved by those skilled in the art. Summary of the Invention

[0012] The purpose of this invention is to provide an automatic switch testing device that requires only one person to complete the test, thereby improving testing efficiency and reducing labor costs.

[0013] To achieve the above objectives, the present invention provides the following technical solution:

[0024] Furthermore, the support platform includes a lower platform, an upper platform, and a first support rod group. The lower platform is mounted on the first drive mechanism, and the upper platform is mounted above the lower platform at intervals through the first support rod group. An elastic element is sandwiched between the bottom surface of the upper platform and the first support rod group. The mounting groove is located on the upper platform, and the probe structure is mounted on the lower platform.

[0025] Furthermore, the probe structure includes a mounting base, a slider, a probe, and a positioning assembly;

[0026] The mounting base is fixedly mounted on the lower platform.

[0027] The slider is configured in multiple ways, and each slider is slidably connected to the mounting base in a direction parallel to the bottom surface of the shielding box. At least one probe is inserted into each slider.

[0028] The positioning component is connected to the mounting base and each of the sliders, and the positioning component is used to lock the position of each slider relative to the mounting base.

[0029] Furthermore, it also includes a support platform and a second support rod assembly installed inside the shielding box. The two ends of the second support rod assembly are respectively connected to the shielding box and the support platform. The support platform is located above the product carrying mechanism and has a mounting through hole.

[0030] Furthermore, the product pressing mechanism includes a second driving mechanism and a pressing platform mounted on the second driving mechanism. The second driving mechanism is connected to the support platform and passes through the mounting through hole.

[0036] The automatic switch testing device provided by this invention can produce the following beneficial effects:

[0037] When the aforementioned automatic switch testing equipment is in operation, the tester places the product on the product carrying mechanism, then closes the shielding box. The product carrying mechanism then moves the product directly under the product pressing mechanism. The pressing mechanism then presses down on the product, bringing it into contact with the probe structure and energizing it. Simultaneously, the button pressing mechanism presses the high-voltage switch on the product, activating the screen. During this process, the image acquisition mechanism captures the screen status in real time, testing the screen's functionality. The button pressing mechanism then presses each button on the product to determine if they are functioning correctly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0052] This embodiment provides an automatic switch testing device, such as... Figures 1 to 3 As shown, the device includes a shielded box 1 and a testing device located inside the shielded box 1. The testing device includes: a product carrying mechanism 2 for driving the product to move back and forth; a probe structure 3 mounted on the product carrying mechanism 2; a product pressing mechanism 4 mounted above the product carrying mechanism 2, which presses down the product to make the product contact the probe structure 3 and conduct electricity; a button pressing mechanism 5 mounted above the product carrying mechanism 2, which presses the high-voltage switch and various buttons on the product; and an image acquisition mechanism 6 for monitoring the status of the product screen.

[0053] In the automatic switch testing equipment provided in this embodiment, the product carrying mechanism 2, product pressing mechanism 4, probe structure 3, button pressing mechanism 5, and image acquisition mechanism 6 work together to test the screen. The product carrying mechanism 2, product pressing mechanism 4, probe structure 3, and button pressing mechanism 5 work together to test each button. Therefore, the above equipment can be manually operated within its own shielded box 1, eliminating the need for one person to test the product and then hand it over to another person to place it in the shielded box 1 for testing. One person can complete the product testing, resulting in high testing efficiency and reduced labor costs.

[0054] The following is a detailed description of shielding box 1:

[0055] In some embodiments, such as Figure 1 As shown, to facilitate the opening and closing of the shielding box 1, the shielding box 1 includes a box body 11, a cover 12 and a telescopic mechanism 13. The cover 12 is rotatably connected to the box body 11. The box body 11 is equipped with an indicator light group 14 and a terminal block 15, both of which are electrically connected to the probe structure 3. The two ends of the telescopic mechanism 13 are rotatably connected to the box body 11 and the cover 12 respectively.

[0056] In actual use, the telescopic mechanism 13 performs telescopic movement, and at the same time, its two ends rotate relative to the box body 11 and the cover body 12 respectively, causing the cover body 12 to open or close onto the box body 11. No manual opening or closing is required, making it convenient for testers to place the product on the product carrying mechanism 2.

[0057] It should be noted that the above-mentioned telescopic mechanism 13 can adopt various structural forms, such as pneumatic cylinder, hydraulic cylinder, etc.

[0058] In at least one embodiment, the telescopic mechanism 13 is a pneumatic cylinder, the cylinder body of the pneumatic cylinder is rotatably connected to the housing 11, one end of the piston in the pneumatic cylinder is slidably connected to the cylinder body, and the other end is rotatably connected to the cover 12.

[0059] The indicator light group 14 inside the housing 11 can be used to determine whether each button on the product is qualified. The indicator light group 14 can include indicator lights that correspond to each button. When a button on the product is pressed, the indicator light corresponding to that button flashes, which proves that the button is qualified. If the indicator light corresponding to that button does not respond, it proves that the button is unqualified.

[0060] The terminal block 15 inside the enclosure 11 can be customized, integrating power supply, air supply and communication interface to achieve a simple, compact and modular design for the equipment.

[0061] The housing 11 includes a base plate and multiple side plates connected to the base plate. The multiple side plates are connected in sequence. The product bearing mechanism 2, the product pressing mechanism 4, and the button pressing mechanism 5 are all installed on the base plate. The base plate is set parallel to the horizontal plane.

[0062] In some embodiments, a first information acquisition device 16 is installed on the housing 11. When the cover 12 is fastened to the housing 11, the first information acquisition device 16 acquires the positioning information of the cover 12. The first information acquisition device 16 can be connected to the controller to send the positioning information to the controller. The controller controls the product carrying mechanism 2 to move the product to the bottom of the product pressing mechanism 4, that is, to the detection position.

[0063] The first information acquisition component 16 and the second information acquisition component mentioned above can be micro switches, or pressure sensors, infrared sensors, etc.

[0064] In some embodiments, a second information acquisition device is installed on the housing 11. The second information acquisition device is used to acquire the flashing information of the display light group 14. The second information acquisition device can be connected to the controller. After each button is tested, the controller receives the signal sent by the second information acquisition device, controls the product pressing mechanism 4 to rise, then controls the product carrying mechanism 2 to return to the initial position, and finally controls the cover 12 to open.

[0065] The second information acquisition device mentioned above can be a photosensitive sensor.

[0066] The following is a detailed description of the product support mechanism 2:

[0067] The product carrying mechanism 2 can move the product back and forth in a horizontal direction, that is, parallel to the bottom surface of the housing 11, or in a vertical direction, that is, perpendicular to the bottom surface of the housing 11, or in other oblique upward or downward directions. The fundamental purpose of the reciprocating movement of the product carrying mechanism 2 is to: before placing the product, move it to a position that is convenient for the tester to place the product on it, so as to avoid the problem that the product is not easy to place on the product carrying mechanism 2 due to the obstruction of the product pressing mechanism 4 and the button pressing mechanism 5 above; after the product is placed, move it to the testing position.

[0068] In some embodiments, such as Figure 2 and Figure 3 As shown, the product carrying mechanism 2 includes a first driving mechanism 21 and a carrying platform mounted on the first driving mechanism 21; the carrying platform has a mounting groove for carrying the product, and a probe structure 3 is mounted on the carrying platform and is located below the mounting groove; the first driving mechanism 21 is installed inside the shielding box 1, and the first driving mechanism 21 is used to drive the carrying platform to move in a direction parallel to the bottom surface of the shielding box 1, so that the product on the carrying platform moves closer to or away from the product pressing mechanism 4.

[0069] The product carrier mechanism 2 described above has a simple structure. The product is transferred via the movement of the carrier platform, making it easier for testing personnel to install the product onto the product carrier mechanism 2. The mounting slot restricts the product's placement, ensuring precise alignment of the product with the probe structure 3.

[0070] It should be noted that any structure capable of moving the support platform in a direction parallel to the bottom surface of the shielding box 1 can be the first drive mechanism 21 mentioned in the above embodiments. For example, the first drive mechanism 21 can be a linear motion device such as a pneumatic slide, or a combination of a rotary motion device such as a motor and a linkage assembly, whereby the linkage assembly converts the rotary motion of the motor and other devices into linear motion, and so on.

[0071] In at least one embodiment, the product carrying mechanism 2 is a pneumatic slide, on which a first set of sensors and a second set of sensors connected to a controller are mounted. When the pneumatic slide moves the product to the detection position, the first set of sensors sends a first positioning signal to the controller, which then controls the pneumatic slide to stop sliding and controls the product pressing mechanism 4 to press down the product, making the product contact and energize the probe structure 3. When the pneumatic slide returns the product to the initial position, the second set of sensors sends a second positioning signal to the controller, which then controls the pneumatic slide to stop sliding and controls the cover 12 to open.

[0072] In some embodiments, such as Figure 3 As shown, the support platform includes a lower platform 22, an upper platform 23, and a first support rod group 24. The lower platform 22 is mounted on the first drive mechanism 21. The upper platform 23 is mounted above the lower platform 22 at intervals through the first support rod group 24. An elastic element 25 is sandwiched between the bottom surface of the upper platform 23 and the first support rod group 24. The mounting groove is located on the upper platform 23. The probe structure 3 is mounted on the lower platform 22.

[0073] In practical use, the first drive mechanism 21 moves the lower platform 22, causing the upper platform 23, which is connected to the lower platform 22 via the first support rod assembly 24, to move below the product pressing mechanism 4. The product pressing mechanism 4 overcomes the elastic force of the elastic element 25 and presses down on the product, causing the contacts on the back of the product to contact the probe structure 3, which then supplies power to the product. After the test is completed, the product pressing mechanism 4 resets, and the upper platform 23 resets under the elastic force of the elastic element 25, thus releasing the product from contact with the probe structure 3.

[0074] The aforementioned support platform has a simple structure. It can cooperate with the product pressing mechanism 4 to switch the connection state between the product and the probe structure 3, realize the automatic reset of the product, simplify the structure of the test equipment, and speed up the test efficiency.

[0075] Specifically, the lower platform 22 can be detachably connected to the first drive mechanism 21, such as by screws or snap-fit. The lower platform 22 can be a plate-like structure. The first support rod group 24 can include two, three, four, or more first support rods. One end of the first support rod is connected to the lower platform 22, and the other end is connected to the upper platform 23. The connection can be made by bolts, nuts, or other connecting parts. The upper platform 23 can be a plate-like structure with a mounting groove recessed on its top surface. After the product pressing mechanism 4 presses down the product, the probe structure 3 can extend into the mounting groove and contact the contact point on the back of the product.

[0076] The elastic element can be a spring, an elastic sheet, etc.

[0077] The following is a detailed description of probe structure 3:

[0078] In some embodiments, such as Figures 3 to 5 As shown, the probe structure 3 includes a mounting base 31, sliders 32, probes 33, and a positioning assembly 34. The mounting base 31 is fixedly mounted on the lower platform 22. Multiple sliders 32 are configured, each slider 32 being slidably connected to the mounting base 31 along a direction parallel to the bottom surface of the shielding box 1. At least one probe 33 is inserted into each slider 32. Before installing the product, the user can move the required sliders 32 to the appropriate position according to the product model. After moving them, the positioning assembly 34 is connected to the mounting base 31 and each slider 32 to lock the position of each slider 32 relative to the mounting base 31.

[0079] like Figure 4 As shown, the mounting base 31 has a front and a back, the front being... Figure 4 The middle side faces right, and the back side is... Figure 4 On the left-hand side of the mounting base 31, the probe 33 is mounted to the front of the mounting base 31 via a slider 32, facilitating the movement of the probe 33 by the testing personnel. Figure 5As shown, a slider handle window 311 is provided on the back of the mounting base 31, and the inspector can also move each slider 32 by sliding the slider handle window 311.

[0080] The sliders 32 can be specifically configured to be two, three, or four. In at least one embodiment, such as Figure 5 As shown, there are three sliders 32, with one probe 33 inserted in the left slider 32, two probes 33 inserted in the middle slider 32, and one probe 33 inserted in the right slider 32.

[0081] The positioning component 34 may include a plurality of positioning pins that are connected one-to-one with a plurality of sliders 32, and the positioning pins are preferably elastic positioning pins.

[0082] In some embodiments, such as Figure 6 As shown, to facilitate the installation of the product pressing mechanism 4 and the button pressing mechanism 5, the above-mentioned automatic switch testing equipment also includes a support platform 7 and a second support rod group 8 installed in the shielding box 1. The two ends of the second support rod group 8 are respectively connected to the shielding box 1 and the support platform 7. The support platform 7 is located above the product bearing mechanism 2, and the support platform 7 has a mounting through hole 71.

[0083] The support platform 7 can be used to install the product pressing mechanism 4 and the button pressing mechanism 5, ensuring that the product pressing mechanism 4 and the button pressing mechanism 5 are placed above the product carrying mechanism 2. It is not necessary for the product pressing mechanism 4 and the button pressing mechanism 5 to be installed in the shielding box 1 through different support structures, thus simplifying the structure inside the shielding box 1.

[0084] The second support rod group 8 may include two, three, four or more second support rods. One end of the second support rod is connected to the bottom wall of the shielding box 1, and the other end is connected to the support platform 7. Specifically, the connection can be made by bolts, nuts or other connecting parts.

[0085] The following is a detailed description of the product pressing mechanism 4:

[0086] In some embodiments, such as Figures 6 to 8 As shown, the product pressing mechanism 4 includes a second drive mechanism 41 and a pressing platform 42 mounted on the second drive mechanism 41. The second drive mechanism 41 is connected to the support platform 7 and passes through the mounting through hole 71. The second drive mechanism 41 is used to drive the pressing platform 42 to press down the product. The surface of the pressing platform 42 facing the product bearing mechanism 2 is provided with a first buffer layer. The first buffer layer can buffer the impact force of the pressing platform 42 on the product and avoid damage to the product.

[0087] Since the movement direction of the lower pressure platform 42 is vertical, the second drive mechanism 41 can reduce the vertical dimension of the structure inside the shielding box 1 to a certain extent by passing through the mounting hole 71, and at the same time make the structure inside the shielding box 1 more compact.

[0088] It should be noted that any structure capable of driving the pressing platform 42 to press down the product can be the second drive mechanism 41 mentioned in the above embodiments. For example, the second drive mechanism 41 can be a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc.

[0089] In at least one embodiment, the second drive mechanism 41 is a pneumatic cylinder. The cylinder body is connected to the support platform 7, and one end of the piston in the pneumatic cylinder is slidably connected to the cylinder body, while the other end is connected to the lower pressure platform 42. The second drive mechanism 41 is equipped with a third set of sensors and a fourth set of sensors connected to the controller. When the second drive mechanism 41 drives the lower pressure platform 42 to press the product into contact with the probe structure 3, the third set of sensors sends a third positioning signal to the controller. The controller then controls the second drive mechanism 41 to stop operating and controls the button pressing mechanism 5 to press the high-voltage switch on the product. When the second drive mechanism 41 drives the lower pressure platform 42 to reset, the fourth set of sensors sends a fourth positioning signal to the controller, which then controls the second drive mechanism 41 to stop operating.

[0090] To ensure stable pressing of the product by the lower pressure table 42, two second drive mechanisms 41 are configured.

[0091] In addition, the pressure table 42 has a buffer layer fixing platform, which can be manufactured by 3D printing. The first buffer layer is detachably connected to the buffer layer fixing platform, facilitating the replacement of the first buffer layer. The first buffer layer can effectively mitigate the impact force of the pressure table 42 during testing, simulating the pressing sensation of a human hand.

[0092] The following is a detailed description of the button pressing mechanism 5:

[0093] In some embodiments, such as Figures 6 to 8 As shown, the button pressing mechanism 5 includes a third driving mechanism 51, a first pressing head 52, multiple fourth driving mechanisms 53, and multiple second pressing heads 54 connected one-to-one with the multiple fourth driving mechanisms 53; the third driving mechanism 51 and the fourth driving mechanism 53 are both connected to the support platform 7 and pass through the mounting through hole 71. The third driving mechanism 51 is used to drive the first pressing head 52 to press the high-voltage switch on the product, and the fourth driving mechanism 53 is used to drive the second pressing head 54 to press the button on the product; the surfaces of the first pressing head 52 and the second pressing head 54 facing the product carrying mechanism 2 are both provided with a second buffer layer.

[0094] The fourth drive mechanism 53 can be two or three. In at least one embodiment, such as Figure 6 As shown, there are three fourth drive mechanisms 53, which makes the above-mentioned automatic switch testing device applicable to testing single-button, double-button, and triple-button switches.

[0095] The aforementioned button pressing mechanism 5 can press the high-voltage switch and each button individually. Each pressing action is achieved through an independent drive mechanism, so they will not affect each other, thus ensuring testing efficiency.

[0096] The structures of the third drive mechanism 51 and the fourth drive mechanism 53 are similar to those of the second drive mechanism 41. To save space, they will not be described in detail here.

[0097] In at least one embodiment, both the third drive mechanism 51 and the fourth drive mechanism 53 are pneumatic cylinders. The third drive mechanism 51 is equipped with two sets of sensors connected to the controller, and the fourth drive mechanism 53 is equipped with two sets of sensors connected to the controller. These sensors are used to collect positioning information of the third drive mechanism 51 and the fourth drive mechanism 53 in the pressed state and the reset state, and send this information to the controller, which then controls the next mechanism to operate.

[0098] Specifically, firstly, the third drive mechanism 51 controls the first pressing head 52 to press the high-voltage switch on the product. The image acquisition mechanism 6 detects the screen status of the product in real time and acquires the displayed image on the screen. The content may include the current status of the product, whether the Bluetooth connection is successful, time, temperature, and other icons. The visual detection algorithm determines whether the screen display is qualified. The detection result is sent to the controller for judgment. If qualified, the test continues; if unqualified, the test automatically exits. If the controller determines that the screen test is unqualified, the controller controls the product support mechanism 2 to return to the initial position. After the product support mechanism 2 is in position, the second set of sensors transmits the second positioning signal to the controller. The controller controls the cover 12 to open and uses an indicator light (red light) to indicate to the operator that the test is unqualified. If the controller determines that the screen test is qualified, the controller controls each fourth drive mechanism 53 to act sequentially. The controller will activate the corresponding number of fourth drive mechanisms 53 for different switch models according to the preset program to press down the buttons on the product in sequence.

[0099] by Figure 7 Taking this as an example, the test equipment is equipped with three second pressing heads 54, namely second pressing head 1, second pressing head 2, and second pressing head 3, corresponding to the three buttons on the switch, and compatible with the button positions of three different models. For a single-button switch, only second pressing head 1 is activated; for a double-button switch, second pressing heads 1 and 2 are activated sequentially; for a three-button switch, second pressing heads 1, 2, and 3 are activated sequentially. If the buttons are pressed correctly, the indicator lights in the indicator light group 14 will be lit, and the result is determined by a photosensitive sensor installed next to the indicator lights.

[0100] It should be noted that the above-mentioned image recognition feedback, preset program, and control of the actions of each fourth drive mechanism 53 are all technologies known in the field, and will not be described in detail here for the sake of saving space.

[0101] The image acquisition mechanism 6 is described in detail below:

[0102] In some embodiments, such as Figure 8 As shown, the image acquisition mechanism 6 includes a visual light source 61 and a visual camera 62, which are mounted on the support platform 7.

[0103] The visual light source 61 provides a light source for the visual camera 62 to capture images, ensuring that the visual camera 62 can clearly capture images of the product screen.

[0104] In at least one embodiment, such as Figure 6 As shown, the vision camera 62 is connected to the support platform 7 via a connecting rod. An adjusting block 9 is installed between the vision camera 62 and the connecting rod, and the adjusting block 9 can adjust the height of the vision camera 62 relative to the connecting rod. Figure 8 As shown, the visual light source 61 is connected to the support platform 7 through a bending plate, so that there is a certain distance between the visual camera 62 and the product, ensuring that the light source fully illuminates the product.

[0105] Among them, such as Figure 6 As shown, the adjusting block 9 can be clamped onto the connecting rod by a locking nut, as... Figure 8 As shown, the vision camera 62 is connected to the side of the adjustment block 9, and the height of the adjustment block 9 relative to the connecting rod can be adjusted and locked by loosening and tightening the locking nut.

[0106] In addition, the bending plate can be connected to the visual light source 61 via a universal joint, making the angle of the visual light source 61 adjustable.

[0107] In some embodiments, the automatic switch testing equipment further includes the controller described above. The controller is connected to the housing 11, the product carrying mechanism 2, the product pressing mechanism 4, the button pressing mechanism 5, and the image acquisition mechanism 6 to control the working sequence of the housing 11, the product carrying mechanism 2, the product pressing mechanism 4, the button pressing mechanism 5, and the image acquisition mechanism 6.

[0108] Specifically, the controller is used to receive signals from each sensor, control the corresponding structure of the sensor to stop operating based on the signals, and control the next mechanism to operate the product, ensuring the automatic operation of the testing equipment.

[0109] In some embodiments, the shielding box 1 is equipped with an indicator light connected to the controller. The indicator light is used to display the product's pass / fail status. The indicator light may include a red light and a green light; if the product is unqualified, the red light will illuminate, and if the product is qualified, the green light will illuminate.

[0110] The aforementioned controller can be implemented using structures such as industrial control computers. In other words, the control process of the aforementioned controller is a well-known technology in this field, and to save space, it will not be described in detail here.

[0111] The controller can also upload test results to a host computer via a communication module for easy product traceability. The monitor next to the device will also display a screen to prompt the operator with the test results. If the test is unqualified, the reason for the unqualified result will be displayed.

[0112] It should be noted that, in addition to its testing function, the automatic switch testing equipment provided in the above embodiments can also be used for product fatigue testing to determine whether there are quality defects in the various components of the product.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
