Description

Technical Field

[0001] This utility model belongs to the field of electronic equipment technology, specifically, it relates to an electronic circuit testing device. Background Technology

[0002] Electronic circuits refer to circuits composed of electronic devices and related radio components. They include circuits for amplification, oscillation, rectification, detection, modulation, frequency conversion, waveform conversion, and various control circuits. They are widely used in various electronic devices.

[0003] Chinese patent CN220092208U discloses an electronic circuit testing device, including a workbench, a working slot, a PLC programmable controller, a testing mechanism, and a sorting component. The sorting component includes a first motor, a main spindle, and a secondary spindle. The output end of the first motor is fixedly connected to the main spindle. A conveyor belt is provided on the outer wall of the main spindle and the secondary spindle. The conveyor belt is installed in the working slot. A mounting block is provided on the front end face of the workbench. A mounting slot is provided in the mounting block. A second motor is provided in the mounting slot. A baffle is provided on the output end of the second motor. The above-mentioned prior art tests components through a testing mechanism. Since the components pass directly under the testing mechanism, it is mostly a non-contact visual test, with limited testing effect and inability to perform current testing on components.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an electronic circuit testing device that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: An electronic circuit testing device includes: a conveyor belt, characterized in that a conveyor motor is provided at the front end of the conveyor belt, side plates are provided on both sides of the conveyor belt, square holes are opened on the surface of the side plates, a base is provided inside the square holes, a clamping mechanism is provided on the top of the base, a guide rail is provided on the clamping mechanism facing the conveyor belt, a chuck is provided at the front end of the guide rail, a test pen is provided inside the chuck, a bracket is provided on the top of the side plates, a test box is installed on the top of the bracket, and the test box and the test pen are connected by a connecting wire.

[0007] Optionally, a first adjustment knob is installed horizontally through the clamping mechanism near the top of the base.

[0008] Optionally, a fixing knob is horizontally mounted on the clamping mechanism near the guide rail.

[0009] Optionally, the clamp is provided with a locking knob facing the center of the conveyor belt.

[0010] Optionally, a hydraulic cylinder is provided below the conveyor belt, a support plate is provided on the top of the hydraulic cylinder, and the two sides of the support plate are installed at the bottom of the base.

[0011] Optionally, the conveyor belt is provided with a tray below the bracket.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: This electronic circuit testing device controls the height of the test pen by fixing it to the clamp with a locking knob, and controls the longitudinal position of the clamping mechanism on the base with an adjustment knob. The length of the guide rail extending from the clamping mechanism controls the lateral distance of the test pen, thus allowing the test pen to be adjusted in three directions. The device tests the electronic circuit of components through the test box. After adjustment, it can perform current tests on various circuits, thus improving the versatility of the device.

[0013] This electronic circuit testing device uses a conveyor belt to transport pre-placed components. A hydraulic cylinder controls the support plate to lift the bases on both sides, thereby lifting the clamping mechanism. After the components are transported to the designated position, the hydraulic cylinder drives the clamping mechanism to lower. The testing pen contacts the components to perform measurements. Finally, the clamping mechanism is lifted again, and the conveyor belt sends the components out. This process is repeated to continuously test the components transported from the conveyor belt, thus automating the testing process.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Please see Figure 1-6 As shown, this embodiment provides an electronic circuit testing device, including: a conveyor belt 1.

[0020] like Figure 1-6 As shown, in this embodiment, a conveyor motor 101 is provided at the front end of the conveyor belt 1, and side plates 2 are provided on both sides of the conveyor belt 1. A square hole 201 is opened on the surface of the side plate 2, and a base 301 is provided inside the square hole 201. A clamping mechanism 3 is provided on the top of the base 301, and a guide rail 303 is provided on the clamping mechanism 3 facing the conveyor belt 1. A chuck 305 is provided at the front end of the guide rail 303, and a detection pen 402 is provided inside the chuck 305. A bracket 4 is provided on the top of the side plate 2, and a detection box 401 is installed on the top of the bracket 4. The detection box 401 and the detection pen 402 are connected by a connecting line 403. The device is formed by providing side plates 2 on both sides of the conveyor belt 1 and clamping mechanisms 3. The base 301 is installed in the square hole 201 of the side plate 2. The clamping mechanism 3 extends the clamp 305 above the conveyor belt 1 in the middle. The detection pen 402 is installed in the clamp 305 and is connected to the detection box 401 through the connecting line 403. The detection pens 402 at the ends of the connecting lines 403 extend from the left and right of the detection box 401 and are fixed to the two clamps 305. When the two detection pens 402 come into contact with the components, the induction circuit is generated and captured by the detection box 401, thereby forming a circuit to test whether the components are working properly. The entire detection box 401 is supported by the bracket 4 and the connecting line 403 passes through the hole on the bracket 4 and is connected to the detection pen 402.

[0021] like Figure 6As shown, in this embodiment, a first adjustment knob 302 is horizontally installed above the base 301 in the clamping mechanism 3. The first adjustment knob 302 is connected to a threaded rod that passes through the bottom of the clamping mechanism 3. The threaded rod passes through a threaded hole at the bottom of the clamping mechanism 3. The first adjustment knob 302 drives the threaded rod to rotate, and its thread and the threaded hole are engaged. Since the bottom of the clamping mechanism 3 is attached to the base 301, the whole will not flip. The clamping mechanism 3 moves longitudinally on the top of the base 301 through the drive of the thread, which drives the upper guide rail 303 and the front clamp 305 to adjust the detection pen 402 in the longitudinal direction.

[0022] like Figure 5 , 6 As shown, in this embodiment, a fixing knob 304 is horizontally installed on the clamping mechanism 3 near the guide rail 303. The guide rail 303 has a groove on its side, which passes through the square hole on the clamping mechanism 3. The length of the groove extending from the clamping mechanism 3 can be adjusted. By rotating the fixing knob 304, the guide rail 303 is pressed and fixed, thereby adjusting the lateral position of the detection pen 402 on the front end chuck 305 on the conveyor belt 1. The fixing knob 304 works in conjunction with the adjustment knob to adjust the position of the detection pen 402 on the horizontal plane.

[0023] like Figure 3-6 As shown, in this embodiment, a locking knob 306 is provided on the chuck 305 facing the center of the conveyor belt 1. The front end of the locking knob 306 passes through the chuck 305 and contacts the detection pen 402, pressing it against the inner wall of the chuck 305 to fix the height of the detection pen 402. The height of the detection pen 402 is adjusted and then fixed by the locking knob 306 to achieve the height adjustment of the detection pen 402. The adjustment knob 302 and the fixing knob 304 are used to adjust the position of the detection pen 402 in three directions in space.

[0024] like Figure 2 , 3 As shown, a hydraulic cylinder 5 is provided below the conveyor belt 1 in this embodiment. A support plate 501 is provided on the top of the hydraulic cylinder 5, and the two sides of the support plate 501 are installed at the bottom of the base 301. The hydraulic cylinder 5 is installed on the ground, and the top support plate 501 extends to both sides and is installed at the bottom of the base 301 at both ends. When the hydraulic cylinder 5 rises, it lifts the base 301 through the support plate 501, thereby lifting the clamping structure 3 and the detection pen 402 above. The conveyor belt 1 is driven by the conveyor motor 101 to transport the surface components to the corresponding detection positions. The hydraulic cylinder 5 lowers the detection pen 402 to contact the components for measurement. After the measurement is completed, it rises again, and the conveyor motor 101 rotates to send out the components that have been tested. During the repeated lifting and lowering process, the connecting line 403 connecting the detection box 401 and the detection pen 402 needs to be reserved with a relatively long length to avoid being torn.

[0025] like Figure 2 As shown, in this embodiment, a support plate 6 is provided below the bracket 4 for the conveyor belt 1. The two ends of the support plate 6 are installed on the side plate 2, which provides a certain support for the conveyor belt 1. When the conveyor belt 1 transports the component to the top of the support plate 6, the component is tested by contacting the detection pen 402. The support plate 6 supports the conveyor belt 1 and the component, reducing the deformation of the conveyor belt 1 caused by the pressure of the detection pen 402, which would otherwise cause the component to move, thereby improving the accuracy of the test.

[0026] Working principle: Place the test box 401 on the bracket 4. Insert the test pen 402 through the bracket 4 into the clamp 305 for temporary fixation. Place the corresponding component in the test area below the bracket 4. Rotate the adjustment knob 302 and the fixing knob 304 in sequence to align the test pen 402 on the clamp 305 with the two measurement areas on the component. Lower the hydraulic cylinder 5 to its lowest position. At the same time, loosen the fixing knob 304 to adjust the height of the test pen 402 to be able to contact the measurement position. Then, rotate the fixing knob 304 to lock and fix it. At this time, the component is tested by the test and the measurement of 401. The hydraulic cylinder 5 is raised to move the test pen 402 away from the component. The conveyor motor 101 is started to drive the conveyor belt 1 to move and transport the component away. At the same time, the next component is transported to the test area. The hydraulic cylinder 5 is lowered again, and the test pen 402 contacts the component for testing. Record the test results and repeat the above process to achieve batch testing.
