Description

Technical Field

[0002] Low-voltage electrical engineering is a category within the field of electrical applications. Electrical applications can be divided into two categories based on the strength of the power transmission: high-voltage and low-voltage. Among them, the electrical use of buildings and building complexes generally refers to low-voltage electrical systems below AC, whose main purpose is to provide people with electrical energy and convert electrical energy into other energy sources, such as lighting and air conditioning. To ensure the safety of low-voltage electrical engineering, safety inspections are usually required.

[0003] In the production equipment of low-voltage engineering, testing devices are needed to inspect the quality of integrated circuit boards. However, the existing low-voltage engineering testing devices require the integrated circuit board to be placed on the testing surface and then removed after testing. This process is cumbersome and affects the testing efficiency. In addition, when the testing head moves downward to contact the integrated circuit board, pressure is generated at the moment of contact between the testing head and the integrated circuit board, which can squeeze the integrated circuit board and easily cause damage. Utility Model Content

The device can continuously transport circuit boards to the testing box for testing through the feeding component, and then send the circuit boards out after testing, thus forming a continuous testing step, which greatly improves the testing efficiency of circuit boards and avoids the inspection head pressing on the worker's hand. Secondly, the buffer component can alleviate the pressure of the inspection head moving downward, so as to avoid the circuit board being crushed due to excessive pressure when it comes into contact with the circuit board, thus avoiding economic losses.

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1

[0027] like Figures 1-7 As shown, a low-voltage electrical safety testing device includes: a fixed frame 1, a mounting frame 11 fixedly connected to the top of the fixed frame 1, a testing box 12 fixedly mounted on the top of the mounting frame 11, a housing 13 inside the testing box 12, and multiple testing heads 14 below the housing 13; a feeding assembly, which is located on the mounting frame 11 and is used to transport integrated circuit boards to the testing box 12; and a buffer assembly, which is located on the housing 13 and is used to buffer the pressure of the testing heads 14.

[0028] Among them, a pneumatic rod 4 is fixedly installed on the top of the detection box 12. The bottom end of the pneumatic rod 4 passes through the detection box 12 and is connected to the top of the housing 13. Two symmetrically arranged guide rods 41 are fixedly connected to the top of the housing 13. The top ends of the guide rods 41 both pass through the detection box 12 and extend to the outside.

[0029] When inspecting a circuit board, the circuit board is placed on the feeding assembly, which transports it into the inspection box 12. Then, the pneumatic rod 4 pushes the housing 13 downward. As the housing 13 moves downward, it drives the guide rod 41 downward, ensuring that the housing 13 can only move vertically. The housing 13 pushes the inspection head 14 downward to contact the circuit board for inspection. When a non-compliant circuit board is detected, the alarm light on the inspection box 12 will flash. The buffer assembly can buffer the pressure generated when the inspection head 14 is pressed down, preventing excessive pressure from the inspection head 14 from damaging the circuit board. Example 2

[0030] Based on Embodiment 1, the feeding assembly includes: rollers 2, transmission rods 21, conveyor chains 22, reducers 23, moving plates 24, and positioning templates 25. Two rollers 2 are rotatably connected to the inner walls of opposite sides of the mounting frame 11. Transmission rods 21 connect the two opposing rollers 2, and conveyor chains 22 connect the two rollers 2 on the same side. A reducer 23 is fixedly mounted on one side of the mounting frame 11, with one end of its drive shaft connected to the rotation shaft of the rollers 2. Multiple moving plates 24 are fixedly mounted between the two conveyor chains 22. Each moving plate 24 is equipped with a positioning template 25. A receiving groove 26 is opened at the bottom of the positioning template 25, and a top plate 27 is provided inside the receiving groove 26. Through holes a28 are opened on both the moving plates 24 and the positioning templates 25. A connecting rod 29 is provided inside the through hole a28. The top end of the connecting rod 29 is connected to the bottom of the top plate 27. A fitting plate a210 is fixedly connected to the bottom end of the connecting rod 29. A fitting plate b211 is fixedly connected between the inner walls of opposite sides of the mounting frame 11. Four through holes b212 are provided on both the moving plate 24 and the positioning template 25. A limiting rod 213 is provided inside each of the four through holes b212. The top end of the limiting rod 213 is connected to the bottom of the top plate 27. A limiting ring 214 is fixedly connected to the bottom end of each limiting rod 213. Screws 215 are fixedly connected to the four corners of the top of the moving plate 24. Mounting holes 216 are provided at the four corners of the top of the positioning template 25. The four mounting holes 216 are respectively fitted onto the four screws 215 and are externally threaded with nuts 217.

[0031] When testing the circuit board, the reducer 23 is started to drive the connected roller 2 to rotate. Through the transmission rod 21, the two opposing rollers 2 can rotate synchronously. As the rollers 2 rotate, the conveyor chain 22 moves, and the conveyor chain 22 moves the moving plate 24 towards one side of the testing box 12. Simultaneously, the circuit board is placed on the positioning template 25 on the side away from the reducer 23. When the positioning template 25 containing the circuit board moves into the testing box 12 for testing, the reducer 23 stops for a period of time. After testing, the reducer 23 restarts, driving the conveyor chain 22 to move the distance between the two moving plates 24, thus allowing subsequent circuit boards to enter the testing box 12 for testing. The tested circuit boards move to the unloading area. At this time, the mating plate a210 pushes the connecting rod 29 upwards via the mating plate b211. The connecting rod 29 moves along... The top plate 27 is lifted by the movement inside the through hole a28. When the top plate 27 moves, it drives the limiting rod 213 to move along the inside of the through hole b212, thereby restricting the top plate 27 to keep it moving vertically. The limiting ring 214 can limit the movement distance of the limiting rod 213, so that the top plate 27 is moved out of the receiving groove 26 and the circuit board is pushed out of the positioning template 25, so that the circuit board can be taken out. This forms a continuous processing step to improve the detection efficiency. When replacing the positioning template 25, the nut 217 is loosened to release the fixation of the positioning template 25. The positioning template 25 is removed from the screw 215 and replaced with the required positioning template 25. The four mounting holes 216 are fitted onto the four screws 215, and the nuts 217 are screwed onto the screws 215 respectively to fix the positioning template 25 and complete the replacement. Example 3

[0032] Based on Embodiment 1, the buffer assembly includes: a fixed cylinder 3, a cylindrical tube 31, a spring 32, a detector 33, and a cable 34. Multiple fixed cylinders 3 are fixedly connected to the bottom of the housing 13. The detection head 14 is slidably connected to the inside of the fixed cylinder 3. The top of the detection head 14 is fixedly connected to the cylindrical tube 31. The top of the cylindrical tube 31 passes through the fixed cylinder 3 and the housing 13 and extends into the interior. The spring 32 is sleeved on the outside of the cylindrical tube 31. Multiple detectors 33 are provided inside the housing 13. A cable 34 is fixedly connected to one side of the detector 33. One end of the cable 34 passes through the cylindrical tube 31 and is connected to the top of the detection head 14.

[0033] During testing, the detection head 14 moves downward and presses against the circuit board. When the pressure is too high, it retracts into the fixed cylinder 3, thereby squeezing the spring 32 to compress and store energy, which can absorb and offset the pressure. At the same time, it drives the cylindrical tube 31 to move upward and the cable 34 to move, thereby preventing the cable 34 from being squeezed by the spring 32. The detector 33 can analyze the circuit board data to ensure that the circuit board meets the standards.
