Abstract
Description
Technical Field
[0001] This utility model relates to the field of membrane switch testing, specifically a circuit testing device for the production of electronic membrane switches. Background Technology
[0002] An electronic membrane switch is a switching element based on thin film technology. It is usually composed of multiple layers of thin film material and is used to control the switching on and off of current. Its working principle mainly relies on the voltage or capacitance characteristics of the thin film. When an external pressure or electric field is applied, the physical state of the thin film will change, thereby realizing the opening or closing of the switch.
[0003] Circuit testing of electronic membrane switches typically relies on specialized testing equipment to ensure proper switch function, including on / off status, response speed, and trigger signals. Testing usually involves pressing a test probe against the membrane switch. The probe's height is adjusted using a lifting device. Operators position the membrane switch at a prescribed angle, and the lifting device lowers the test probe to press it against the switch. This process detects circuit continuity, response speed, and other parameters, and the signal data is then fed back to a computer.
[0004] Electronic membrane switches of the same model usually come in two types: soft interface and hard interface. This means that circuit testing of electronic membrane switches often requires compatibility with membrane switches of different interfaces, which makes the testing equipment more troublesome to use. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a circuit testing device for the production of electronic thin-film switches, so as to solve the technical problems mentioned in the background.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a circuit testing device for the production of electronic thin-film switches.
[0007] By adopting the above technical solution, including a mounting platform, a hard interface switch, and a soft interface switch, the mounting platform is provided with a workbench and a mounting frame on its top, and a telescopic component is provided at the bottom of the mounting frame, with a detection probe at the bottom of the telescopic component. A rotating platform is rotatably connected between the workbench and the mounting frame, and a locking frame is provided on one side of the rotating platform. Two sets of support frames are provided on the top of the mounting platform, and two sets of guide rods are provided between the two sets of support frames. Multiple sets of first springs are sleeved on the outside of the two sets of guide rods. Two sets of fixing frames are movably installed on the outside of the two sets of guide rods, and the two sets of fixing frames are symmetrically arranged. The two sets of fixing frames are used to clamp and fix the rotating platform.
[0008] The present invention is further configured such that a positioning block is provided on the top of the workbench, and the positioning block is matched with the hard interface switch and the soft interface switch, and an open slot is provided on the top of the workbench.
[0009] Preferably, by setting a positioning block on the top of the workbench that matches the size of the hard interface switch and the soft interface switch, the positioning block can be used to position the hard interface switch and the soft interface switch. Setting an open slot makes it easier to remove the hard interface switch and the soft interface switch after testing.
[0010] The present invention is further configured such that a first bevel gear is provided at one end of the rotary table, and two sets of strip grooves are provided on the top of the rotary table, and a pressure plate is movably installed in the strip grooves.
[0011] Preferably, the pressure plate is movable by setting a strip groove. The pressure plate consists of two sets of long plates and two sets of long rods. The pressure plate is movable in the strip groove and can press the flexible circuit part of the hard interface switch and soft interface switch by gravity on both sides of the rotating table to prevent the flexible circuit from warping during testing.
[0012] The present invention is further configured such that a linkage plate is movably installed at the bottom of the workbench through a limiting groove, and two sets of push plates are symmetrically arranged at one end of the linkage plate. The linkage plate and the workbench are connected by a second spring.
[0013] Preferably, by setting a linkage plate to install a push plate, the movement of the linkage plate can cause the push plate to move and separate the two sets of fixed frames.
[0014] The present invention is further configured such that a knob is rotatably connected to one end of the linkage plate, and a second bevel gear is provided on the outside of the knob, and the second bevel gear and the first bevel gear are connected by a transmission component.
[0015] Preferably, a knob is set on one side of the linkage plate, and a second bevel gear is installed on the knob. Then, the knob is pushed to move the linkage plate, which can drive the push plate to move and separate the two sets of fixed frames. Then, the knob is rotated to drive the second bevel gear to rotate, so that the second bevel gear can drive the first bevel gear to rotate through the transmission assembly, thereby controlling the rotation of the rotary table. The transmission assembly consists of multiple sets of transmission shafts and multiple sets of transmission bevel gears.
[0016] In summary, the present invention has the following main advantages:
[0017] 1. This utility model features a rotatable rotating platform. One side of the rotating platform is used to test soft interface switches, while the other side of the rotating platform is equipped with a locking frame that can lock hard interface switches. Thus, the circuit testing equipment can quickly switch between testing modes by rotating the rotating platform 180°, making it more convenient to switch between soft interface switches and hard interface switches.
[0018] 2. This utility model can clamp and fix the rotary table by setting two sets of fixed frames, thereby improving the stability of the rotary table. The two sets of fixed frames are controlled by a push plate. By pushing the knob, the push plate can be moved to separate the two sets of fixed frames. When the rotary table is released from the restriction of the fixed frames, the rotary table can be quickly flipped by rotating the knob and using the engagement of the transmission component.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0030] The embodiments of this utility model will be described below based on its overall structure.
[0031] Please see Figure 1 - Figure 8 A circuit testing device for producing electronic membrane switches includes a mounting platform 1, a hard interface switch 24, and a soft interface switch 25. A workbench 2 and a mounting frame 5 are mounted on the top of the mounting platform 1. A telescopic assembly 6 is mounted on the bottom of the mounting frame 5, and a test probe 7 is mounted on the bottom of the telescopic assembly 6. The test probe 7 is connected to a computer for testing the circuit conditions of the hard interface switch 24 and the soft interface switch 25. A rotary table 8 is rotatably connected between the workbench 2 and the mounting frame 5, and a locking bracket 12 is mounted on one side of the rotary table 8. The top of the mounting platform 1 is provided with two sets of support frames 13, and two sets of guide rods 14 are provided between the two sets of support frames 13. Multiple sets of first springs 15 are sleeved on the outside of the two sets of guide rods 14. Two sets of fixing frames 16 are movably installed on the outside of the two sets of guide rods 14, and the two sets of fixing frames 16 are symmetrically arranged. The two sets of fixing frames 16 are used to clamp and fix the rotary table 8. By setting two sets of fixing frames 16, the rotary table 8 can be clamped and fixed, thereby improving the stability of the rotary table 8. The two sets of fixing frames 16 are controlled by the push plate 20.
[0032] Please refer to the above embodiments for further details. Figure 1 The top of the workbench 2 is provided with a positioning block 3, which matches the hard interface switch 24 and the soft interface switch 25. The top of the workbench 2 is provided with an open slot 4. By setting the positioning block 3 on the top of the workbench 2 that matches the size of the hard interface switch 24 and the soft interface switch 25, the hard interface switch 24 and the soft interface switch 25 can be positioned. The open slot 4 makes it easier to remove the hard interface switch 24 and the soft interface switch 25 after inspection.
[0033] Please refer to the above embodiments for further details. Figure 6 and Figure 7One end of the rotary table 8 is provided with a first bevel gear 9, and the top of the rotary table 8 is provided with two sets of strip grooves 10. A pressure plate 11 is movably installed in the strip grooves 10. By setting the strip grooves 10, the pressure plate 11 can be movably installed. The pressure plate 11 is composed of two sets of long plates and two sets of long rods. Thus, the pressure plate 11 can move in the strip grooves 10 and is located on both sides of the rotary table 8. By gravity, it can press the flexible circuit parts of the hard interface switch 24 and the soft interface switch 25 to prevent the flexible circuit from warping during testing.
[0034] Please refer to the above embodiments for further details. Figure 4 The bottom of the workbench 2 is movably mounted with a linkage plate 19 through a limiting groove 18, and two sets of push plates 20 are symmetrically arranged at one end of the linkage plate 19. The linkage plate 19 and the workbench 2 are connected by a second spring 23. By setting the linkage plate 19 to install the push plate 20, the movement of the linkage plate 19 can drive the push plate 20 to move, which can separate the two sets of fixed frames 16.
[0035] Please refer to the above embodiments for further details. Figure 4 A knob 21 is rotatably connected to one end of the linkage plate 19, and a second bevel gear 22 is provided on the outside of the knob 21. The second bevel gear 22 and the first bevel gear 9 are connected by a transmission assembly 17. By setting the knob 21 on one side of the linkage plate 19 and mounting the second bevel gear 22 on the knob 21, the knob 21 is pushed to move the linkage plate 19, which can drive the push plate 20 to move and separate the two sets of fixed frames 16. Then, the knob 21 is rotated to drive the second bevel gear 22 to rotate, so that the second bevel gear 22 can drive the first bevel gear 9 to rotate through the transmission assembly 17, thereby controlling the rotation of the rotary table 8. The transmission assembly 17 is composed of multiple sets of transmission shafts and multiple sets of transmission bevel gears.
[0036] In practical operation, when circuit testing of the flexible interface switch 25 is required, the operator first snaps the flexible interface switch 25 into the positioning block 3, then lifts the mounting platform 1 so that the flexible circuit part of the flexible interface switch 25 passes through the pressure plate 11. The weight of the pressure plate 11 can press the flexible circuit part of the flexible interface switch 25 flat. Then, the telescopic component 6 is activated to push the detection probe 7 down. Multiple sets of detection probes 7 descend and press the power interface of the flexible interface switch 25. Then, the testing equipment judges the circuit condition of the flexible interface switch 25 through the feedback of electrical signal data. After the test is completed, the operator takes out the flexible interface switch 25 from the open slot 4.
[0037] When circuit testing of the hard interface switch 24 is required, the operator pushes the knob 21 to move the linkage plate 19 within the limit groove 18. The linkage plate 19 compresses the second spring 23 and pushes the two sets of push plates 20 to move. The two sets of push plates 20 engage with the two sets of fixed brackets 16, and then the two sets of fixed brackets 16 move away from each other, that is, the two sets of fixed brackets 16 release the rotary table 8. As the knob 21 is continued to be pushed, the second bevel gear 22 meshes with the transmission component 17. Next, rotating the knob 21 drives the second bevel gear 22 to rotate. The second bevel gear 22 drives the first bevel gear 9 to rotate through the transmission component 17, thereby causing the rotary table 8 to rotate 180°, thus rotating the rotary table 8. With the locking bracket 12 at the bottom of the stage 8 facing upwards, when the knob 21 is released, the linkage plate 19 and the push plate 20 reset under the reset action of the second spring 23. Then, the two sets of fixing brackets 16 move closer to each other and re-clamp the rotating stage 8 under the reset action of the first spring 15. At this time, the operator can start to test the hard interface switch 24. Similarly, the hard interface switch 24 is locked into the positioning block 3, and then the pressure plate 11 presses the flexible circuit part of the hard interface switch 24 and locks the hard interface of the hard interface switch 24 into the locking bracket 12. The detection probe 7 is lowered, and the circuit of the hard interface switch 24 is tested by using the connection between the detection probe 7 and the hard interface switch 24.
