Description

Technical Field

[0001] The utility model relates to the technical field of membrane switch testing equipment, in particular to a membrane switch testing equipment. Background Art

[0002] The membrane switch is an operating system that integrates key functions, indicating elements, and instrument panels. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. When the membrane switch is pressed, the contact of the upper circuit deforms downward and contacts the plate of the lower circuit. When the finger is released, the contact of the upper circuit rebounds, the circuit is disconnected, and the loop triggers a signal. During the production process of the membrane switch, it will be tested by testing equipment;

[0003] However, most of the existing test equipment only has one fixture for fixing the membrane switch during use, so that the user needs to wait for the membrane switch to be disassembled and reinstalled after the test is completed, which is time-consuming and labor-intensive, and reduces production efficiency;

[0004] In addition, the membrane switch is relatively soft. When it is fixed by a clamp, the bottom of the clamp is made of a relatively hard material, which causes the membrane switch to wrinkle easily when clamped, affecting the test accuracy.

[0005] Therefore, the present application provides a membrane switch testing device to meet the needs. Utility Model Content

[0006] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a membrane switch testing device.

[0007] The technical problem to be solved by the utility model is to provide a membrane switch testing device to solve the problem that the existing membrane switch testing device needs to wait for the membrane switch test to be completed before disassembly and the membrane switch is prone to wrinkling when being fixed.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0009] A membrane switch testing device comprises: a testing device body, a controller is installed on the front of the testing device body, a testing instrument is fixedly connected to the top of the inner wall of the testing device body, a supporting base is arranged around the bottom of the bottom end of the testing device body, and a slide groove arranged at equal distances in the horizontal direction is opened on the bottom surface of the inner wall of the testing device body, an electric slider is slidably connected inside the slide groove, and a placement table is fixedly connected to the top of the electric slider.

[0010] Preferably, the left and right sides of the top of the placement table are fixedly connected with clamp assemblies, the bottom end of the clamp assembly is embedded with a pressure plate, and the left and right sides between the pressure plate and the clamp assembly are fixedly connected with a first spring.

[0011] Preferably, an electromagnet is fixedly connected to the top of the inner wall of the clamp assembly, and an iron sheet is fixedly connected to the middle of the top of the pressure plate.

[0012] Preferably, a sponge board is nested at the bottom end of the pressing plate, and the bottom surface of the sponge board is an outwardly convex arc surface.

[0013] Preferably, rubber strips arranged at equal distances in the transverse direction are embedded in the bottom end of the sponge board.

[0014] Preferably, a movable rod is embedded in the top end of the support base, and a second spring is fixedly connected between the movable rod and the support base.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, by setting a slide groove, when testing the membrane switch, the user can place the membrane switch on the placement table, and there are two placement tables. After placing the membrane switch on any of the placement tables, the electric slider can be started to move it to the bottom of the test instrument for testing. During the test, the user can install another membrane switch to be tested on the other placement table, so that after the test is completed, the placement table will be driven by the electric slider to move out of the test instrument area along the slide groove, and the other installed placement table will be moved by the electric slider along the slide groove to the bottom of the test instrument for testing, thereby improving the test efficiency and eliminating the need to wait for disassembly and installation during the test process.

[0017] In the above scheme, by setting a pressure plate, when the membrane switch is placed on the placement table, the pressure plate can always be pressed down and tightly fit the two sides of the membrane switch above the placement table through the elastic force of the first spring, and the sponge plate at the bottom of the pressure plate is an outward convex arc surface. When fitting the membrane switch, it will first contact the middle of the membrane switch and be subjected to force on both sides, so that the pressure plate is not easy to wrinkle when fixing the membrane switch, thereby improving the test accuracy.

DETAILED DESCRIPTION

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A membrane switch testing device shown in the embodiment of the utility model comprises: a testing device body 1, a controller 101 is installed on the front of the testing device body 1, a testing instrument 102 is fixedly connected to the top of the inner wall of the testing device body 1, a supporting base 4 is arranged around the bottom of the testing device body 1, and a slide groove 2 arranged at equal distances in the horizontal direction is opened on the bottom surface of the inner wall of the testing device body 1, an electric slider 201 is slidably connected inside the slide groove 2, and a placement table 202 is fixedly connected to the top of the electric slider 201;

[0027] The user can place the membrane switch to be tested on the placement table 202, and then start the electric slider 201 to enter the test instrument 102 area along the slide groove 2 for testing. At the same time, the user can place another membrane switch to be tested on another placement table 202. When the test of the membrane switch on one of the placement tables 202 is completed, it will be moved out of the test instrument 102 area along the slide groove 2 through the electric slider 201. At the same time, another placement table 202 can move the membrane switch to be tested to the test instrument 102 for the next test through the electric slider 201 and the slide groove 2, so that the user does not need to wait for the test to be completed before disassembly and installation, thereby improving production efficiency.

[0028] In this embodiment, Figure 2-Figure 5 As shown;

[0029] The top and left sides of the placement table 202 are fixedly connected with a clamp assembly 3, the bottom of the clamp assembly 3 is embedded with a pressing plate 302, and the left and right sides between the pressing plate 302 and the clamp assembly 3 are fixedly connected with a first spring 304;

[0030] When the membrane switch is placed on the placement table 202, the pressing plate 302 can be quickly moved downward to fit the two sides of the membrane switch by the elastic force of the first spring 304, so as to quickly fix the membrane switch;

[0031] An electromagnet 301 is fixedly connected to the top of the inner wall of the clamp assembly 3, and an iron sheet 303 is fixedly connected to the middle of the top of the pressing plate 302;

[0032] When the tested membrane switch needs to be disassembled, the electromagnet 301 is turned on to activate the adsorption of the iron sheet 303, so that the pressing plate 302 moves upward, thereby facilitating the user to disassemble the membrane switch;

[0033] A sponge board 305 is nested at the bottom end of the pressing plate 302, and the bottom surface of the sponge board 305 is an outwardly convex arc surface;

[0034] When the pressing plate 302 presses and fixes one side of the membrane switch downward, the sponge plate 305 will first contact the top of the membrane switch, and the sponge plate 305 is not easy to cause damage to the membrane switch when pressing and fixing it. At the same time, when the arc surface at the bottom of the sponge plate 305 fits the membrane switch, it first contacts the middle of the membrane switch and presses and fixes it on both sides, so that the membrane switch is not easy to wrinkle when fixed;

[0035] The bottom end of the sponge board 305 is embedded with rubber strips 306 arranged in a horizontally equidistant manner;

[0036] When the sponge board 305 presses the membrane switch downward, the rubber strip 306 can increase the friction force on the membrane switch, so that the membrane switch is fixed to the top of the placement table 202 more firmly, thereby improving the fixation;

[0037] A movable rod 401 is embedded in the top of the support base 4, and a second spring 402 is fixedly connected between the movable rod 401 and the support base 4;

[0038] When the testing device body 1 encounters a bumpy road during transportation, the movable rod 401 can buffer the external vibration by squeezing the second spring 402 between the supporting base 4, so that the device has strong shock resistance.
