Description

TECHNICAL FIELD

[0001] The present application relates to the field of electrical switch testing, more particularly to an electrical switch key testing device. BACKGROUND

[0002] An electrical switch is an electrical device that controls the on-off of current. It is one of the most basic and commonly used elements in an electrical circuit; a thin film switch belongs to one of the electrical switches, and the core function of the thin film switch is to change the internal structure by pressing the surface of a specific area (key pattern) by the user, so as to turn on or turn off the circuit, which belongs to a kind of circuit on / off element other than "non-contact metal elastic sheet".

[0003] At present, there are key testing devices for thin film switches in the prior art. The testing method of the testing device is generally to press the key vertically to test the key life performance. Although the key life of the thin film switch can be tested, due to the different use scenarios of the thin film switch, for example, when the thin film switch is applied to kitchen small household appliances or industrial equipment, the surface of the thin film switch may be attached with an oil stain layer. The high-frequency contact of the thin film switch with the oil stain may cause the oil stain to penetrate, thereby causing a short circuit or corrosion of the circuit, unclear identification, affecting use, and some chemical oil stains in the industrial processing field may also corrode the thin film switch panel material or printed circuit. Therefore, when the thin film switch is applied to an environment that may frequently or directly contact oil, oil-containing stains, oily liquids or specific chemical reagents, it is crucial to test the oil stain key before leaving the factory.

[0044] As Figures 4-6 shown, the movable seat 44 is internally connected with a plurality of inclination adjusting assemblies 7 for driving a plurality of pressing parts 5 to rotate respectively, and the inclination adjusting assembly 7 comprises a rotating rod 71 rotatably connected in the movable seat 44, a worm gear one 73 fixedly connected outside the rotating rod 71, a worm one 74 rotatably connected in the movable seat 44 and in transmission connection with the worm gear one 73, a bevel gear one 75 fixedly connected at one end of the worm one 74, a bevel gear two 76 rotatably connected in the movable seat 44 and in transmission connection with the bevel gear one 75, a rotating part 77 rotatably connected on the upper end of the movable seat 44 and fixedly connected with the bevel gear two 76, and a plurality of the extension seats 51 are rotatably connected on one side of the movable seat 44 and fixedly connected with one end of the rotating rod 71.

[0045] The inclination adjusting assembly 7 further comprises a hydraulic cylinder 78 fixed on one side of the extension base 51, a sliding base 79 slidably connected on one side of the hydraulic cylinder 78 and fixed on the extending end of the hydraulic cylinder 78, and an inclination linkage assembly 8 fixed on the sliding base 79 and used for driving the column 53 to move when the extension base 51 is in the inclined state.

[0046] The inclination linkage assembly 8 comprises a guide rod 82 fixed on the upper end of the extension base 51, an L-shaped frame 81 movably sleeved on the outside of the guide rod 82 and fixed on one side of the sliding base 79, two active grooves 84 symmetrically formed on the two sides of the L-shaped frame 81, two rotating rods 85 movably inserted into the two active grooves 84 respectively, two connecting plates 86 fixed on one end of the two rotating rods 85 respectively, and two bolts 87 screwed into the two connecting plates 86 respectively, wherein the top base 57 is provided with two screw grooves 83 matched with the two bolts 87 on the two sides, and the two bolts 87 are screwed into the two screw grooves 83 through the two connecting plates 86 respectively.

[0047] The other end of the rotating rod 71 penetrates through the movable base 44 and is fixed with a counterweight part 72.

[0048] By adopting the above technical scheme, in normal use, the column 53 and the simulated pressing head 56 are vertically erected, realizing vertical pressing. In the state of vertical pressing, the bolt 87 needs to be manually screwed out of the screw groove two 83 in advance, so that the lifting of the top seat 57 will not drive the L-shaped frame 81 to lift. Since users often do not always press vertically during daily operation, it is necessary to simulate the user's inclined pressing at this time. Before simulating the inclined pressing, the bolt 87 needs to be screwed into the screw groove two 83 in advance, the rotating part 77 is manually rotated to drive the bevel gear two 76 to rotate, the bevel gear two 76 drives the bevel gear one 75 and the worm one 74 to rotate, the worm one 74 drives the worm gear one 73 to rotate, and the rotation of the worm gear one 73 can drive the rotating rod 71, the counterweight part 72 and the extension seat 51 to rotate. When the extension seat 51 rotates, it can drive the column 53 and the simulated pressing head 56 to rotate and incline. At this time, the hydraulic cylinder 78 is controlled to extend and drive the sliding seat 79 and the L-shaped frame 81 to lift, the L-shaped frame 81 lifts along the guide rod 82 and supports the top seat 57, and then the air cylinder assembly in the base 1 drives the support rod 41 and the simulated pressing head 56 to descend, so that the simulated pressing head 56 approaches the upper side of the membrane switch. Since the extension seat 51 and the simulated pressing head 56 are in an inclined state, the simulated pressing head 56 will change the point of pressing, and the position of the membrane switch needs to be fine-tuned in advance by the XY double-axis platform 2. Then, the hydraulic cylinder 78 is controlled to retract to drive the L-shaped frame 81 to descend, and the L-shaped frame 81 drives the top seat 57 to descend through the connecting plate 86 and the bolt 87, so that the simulated pressing head 56 presses the key area of the membrane switch. The extension and retraction of the hydraulic cylinder 78 drive the simulated pressing head 56 to reciprocate in the inclined state, which can restore the randomness of manual operation and simulate the user's finger to press the keys of the membrane switch. In this way, the pressure can be concentrated on the edge of the key rather than the center, the shear force of the sealing structure is increased, and the local failure of the sealing ring or the panel delamination problem that cannot be triggered by traditional vertical pressing is exposed. The lateral component force generated by the inclination can cause the simulated pressing head 56 to slide slightly on the contact surface, strengthen the scratching and abrasion effect, and expose the scratch resistance of the printed conductive layer or the oil-repellent coating in advance.

[0049] As shown in Figures 6-8 , the mounting column 55 is provided with a screw groove one 551 at the lower end, and the upper end of the simulated pressing head 56 is provided with a screw end 552 screwed into the screw groove one 551, the lower end of the mounting column 55 is connected with a simulated nail pressing part 9, and the simulated nail pressing part 9 comprises a rotating column two 91 rotatably connected to the lower end of the mounting column 55, a worm gear two 92 fixedly connected to the outside of the rotating column two 91 and located in the inside of the mounting column 55, a rotating seat 94 rotatably connected to the lower end of the mounting column 55 and fixedly connected to the lower end of the rotating column two 91, a simulated nail piece 95 fixedly connected to the lower end of the rotating seat 94, and a worm two 93 rotatably connected to the inside of the mounting column 55 and in transmission connection with the worm gear two 92, and one end of the worm two 93 extends outward through the mounting column 55.

[0050] By adopting the technical scheme, the screwing end 552 of the simulation pressing head 56 can be moved out of the screw groove 551 by rotating the simulation pressing head 56, so that the simulation nail sheet 95 at the lower end of the mounting column 55 is exposed. In actual use, users often use the finger end to press, and some users have nails at the finger end, so these users directly use the nails to press the key area of the membrane switch. For this use scenario, the simulation nail sheet 95 can simulate the scenario that the user presses the key area by the nails when there is dirt on the membrane switch, so that the local pressure is increased. In the scenario that the key surface is easy to scratch, the key test is performed on the membrane switch, which can expose problems such as scratching, peeling of the surface coating, fracture of the conductive path due to point pressure, cracking of the panel due to non-uniform stress, and the like. Meanwhile, the simulation nail sheet 95 can also cooperate with the inclination adjusting assembly 7 to perform the finger pressing key test in the inclined state, simulate the dynamic behavior of the user (simulate that the nails are accidentally scratched, pass through the key surface and press when the simulation nail sheet 95 has an inclination), and the test scenario is more comprehensive.
