[0002] Membrane switches, as an operating system integrating button functions, indicator elements, and instrument panels, are widely used in electronic communication, electronic measurement instruments, industrial control, medical equipment, automotive industry, smart toys, and home appliances.

[0003] A search revealed that patent publication number CN213398839U discloses a membrane switch performance testing device, addressing the shortcomings of existing technologies. The device includes a testing base with a connecting plate fixed to one side by countersunk bolts. Through the arrangement of a mounting plate, a test plate, a first connecting rod, a second connecting rod, and a fixture base, when force is applied by personnel, the upper mounting plate, carrying the test plate, moves closer to the workpiece. Simultaneously, the first and second connecting rods actuate, drawing the fixture plate containing the product into an inner groove for rapid testing. After testing, the test plate is lifted, and the fixture base automatically slides out of the testing base for easy part removal, improving testing efficiency. The inventors discovered the following problems with existing technologies during the development of this utility model:

[0004] In terms of automation, some equipment still relies heavily on manual operation. From the placement of the membrane switch to the control of the detection process and the recording of the detection results, there is a lot of human intervention. This not only leads to low detection efficiency, but also easily introduces errors due to human factors, affecting the stability of the detection results. In terms of detection accuracy, some equipment has insufficient structural design or component stability, and the load-bearing components are prone to displacement during the detection process, which causes the inspection rod to not act accurately on the membrane switch, thus affecting the accuracy of the detection data.

[0005] Therefore, a membrane switch performance testing device is proposed to address the above problems. Utility Model Content

Example 2

[0026] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, the telescopic rod 4 extends through the top center of the cylinder 3, ensuring smooth telescopic movement. After passing through the top of the cylinder 3, the telescopic rod 4 continues to extend downward until it penetrates into the internal space of the fixed frame 2. The fixed frame 2 provides sufficient range of motion for the telescopic rod 4, allowing it to move stably up and down within the fixed frame 2 under the drive of the cylinder 3, thus providing a reliable guarantee for the operation of the entire device.

[0028] As a preferred embodiment, the left and right ends of the support plate 5 are fixedly installed with fixing plates 6 by welding. The welding process ensures the connection strength between the fixing plate 6 and the support plate 5, and can withstand a certain external force without loosening. The upper side of the fixing plate 6 is provided with through holes. The edges of the through holes are polished, smooth and burr-free. The through holes are uniform in size and neatly arranged, so as to stably connect or fix the support plate 5 with other components and meet the usage requirements in different scenarios.

[0029] In a preferred embodiment, a limiting rod 7 is movably installed inside the fixing plate 6. The limiting rod 7 is a straight cylinder and is fitted with the fixing plate 6 with a clearance, allowing the limiting rod 7 to slide smoothly up and down within the fixing plate 6. The limiting rod 7 is positioned vertically above the base 1, ensuring the stability of its movement direction and effectively limiting the displacement deviation of related components in the vertical direction. An anti-detachment block 8 is fixedly installed on the top of the limiting rod 7 by welding. The size of the anti-detachment block 8 is larger than the aperture of the hole on the fixing plate 6 for the limiting rod 7 to move, which can prevent the limiting rod 7 from accidentally detaching from the fixing plate 6.

[0030] In a preferred embodiment, a fixing plate 9 is tightly connected to the top of the support plate 5 by evenly distributed bolts. The fixing plate 9 is generally flat and square, and its surface is finely polished to be smooth and flat. The telescopic rod 4 and the support plate 5 are positioned by the fixing plate 9 during assembly. The shape and installation position of the fixing plate 9 can guide the telescopic rod 4 to dock with the support plate 5, ensuring the stability of their relative positions.

[0031] In a preferred embodiment, a control switch 12 is movably installed on the front side of the base 1. The control switch 12 is connected to the base 1 by being pressable. The control switch 12 has a simple overall appearance and clear markings on its surface to distinguish different functional modes. The operator only needs to press the control switch 12 lightly to issue corresponding commands to the device, thereby controlling the start, stop or adjust the working state of components such as the cylinder 3, and realizing effective control over the operation of the entire device.

[0032] In a preferred embodiment, the interior of the placement compartment 16 is uniformly equipped with fixing frames 17. The fixing frames 17 are of the same size and arranged neatly. They are fixed in the placement compartment 16 by slots. The interior of the fixing frames 17 is provided with compression springs 18. The interior of the fixing frames 17 has a suitable space reserved for the compression springs 18 to be detachably placed, which facilitates the replacement or maintenance of the compression springs 18 in the future. The compression springs 18 have good elastic properties. The bottom of the compression springs 18 is fixedly installed with a compression rod 19 by welding. The compression rod 19 can realize the extension and retraction movement under the action of the compression springs 18.

[0033] In a preferred embodiment, an inspection rod 20 is provided at the end of the compression rod 19 away from the compression spring 18. The inspection rod 20 is a slender cylindrical shape with a smooth surface and wear-resistant treatment to ensure its service life and detection accuracy. The inspection rod 20 and the compression rod 19 are tightly fixed together by threads to ensure that they will not loosen during movement. The inspection rod 20 extends vertically downward and is located directly above the placement plate 11. When the bearing plate 5 pushes the inspection rod 20 down, relevant inspection operations can be performed on the items placed on the placement plate 11.

[0034] The working process of this utility model is as follows: In use, firstly, the membrane switch to be tested is placed stably on the placement plate 11 in the middle area of ​​the base 1, ensuring the membrane switch is accurately positioned directly below the inspection rod 20. Next, the operator starts the equipment by pressing the control switch 12 on the front side of the base 1. The cylinder 3 begins to work, driving the telescopic rod 4 downwards. Then, the telescopic rod 4 moves the support plate 5 downwards. The support plate 5 moves the mounting frame 10, the internal fixing frame 17, the compression spring 18, the compression rod 19, and the inspection rod 20 downwards together. The inspection rod 20 gradually approaches and finally contacts the membrane switch placed on the placement plate 11. As the support plate 5 continues to move downwards, the compression rod 19 presses down... The compression spring 18, in conjunction with subsequently added pressure sensors, displacement sensors, and other detection elements, collects pressure data on the membrane switch and displacement data of the compression rod 19. The data collected during the test is transmitted to the display 15, where the operator can visually view the test data and determine whether the membrane switch's performance is qualified according to preset standards. After the test is completed, the operator presses the control switch 12 again to stop the cylinder 3 from working. Then, the telescopic rod 4 drives the support plate 5 and inspection rod 20 and other components to move upwards, returning to the initial position, and the tested membrane switch is removed from the placement plate 11. If it is necessary to continue testing the next membrane switch, the steps can be repeated.
