Description

Technical Field

[0001] This utility model relates to the field of tracking and leakage testing technology for automotive plastic parts, specifically a tracking and leakage testing machine for automotive plastic parts. Background Technology

[0002] The automotive plastic parts leakage and tracking test machine can simulate the environmental conditions that automotive plastic parts may encounter during actual use, such as humidity and pollution. By applying a certain voltage and current to the surface of the automotive plastic parts and adding conductive liquid, it observes whether leakage and tracking phenomena will appear on the surface, thereby accurately evaluating the insulation performance of automotive plastic parts. This is crucial for ensuring the safe operation of electrical equipment in humid environments, because automotive plastic parts with good insulation performance can effectively prevent current leakage and avoid electric shock accidents and equipment failures.

[0003] A search revealed a stainless steel test frame for a tracking current testing machine, application number CN201721784318.9. This tracking current testing machine has only a single station, which means that only one automotive plastic part can be tested at a time. After the test is completed, the operator needs to remove the automotive plastic part and clean the conductive liquid on the surface before the next plastic part can be tested. This single-station design results in a lot of waiting time during the test process, making continuous testing impossible and greatly reducing the testing efficiency. Utility Model Content

The motor 31 is fixed to the right side of the mounting box 2, and the output shaft of the motor 31 passes through the interior of the mounting box 2. The threaded rod 32 is rotatably connected to the interior of the mounting box 2. The threaded sleeve 33 is threadedly connected to the middle part of the surface of the threaded rod 32 and the left side of the surface of the threaded rod 32. The connecting piece 34 is fixed to the top of the threaded sleeve 33. The through groove 35 is opened at the top of the mounting box 2. The connecting plate 36 is fixed to the bottom of the test bench 4, and the top of the connecting piece 34 passes through the through groove 35 and connects with the connecting plate 36. The bottom of the connecting plate 36 is fixedly connected, and guide strips 16 are fixed on the top of the front and rear sides of the mounting box 2. Guide blocks 17 are fixed on the front and rear sides of the bottom of the connecting plate 36, and the guide strips 16 pass through the guide blocks 17 and slide between them. When the motor 31 is turned on, the output shaft of the motor 31 will drive the threaded rod 32 to rotate. The threaded sleeve 33 drives the upper connecting plate 36 to move through the connecting piece 34, thereby moving the position of the upper test bench 4 so as to switch the position between the test benches 4 and facilitate the leakage current tracking test on the automotive plastic parts on the surface of the test bench 4.

[0025] Guide rods 20 are provided through the front and rear sides of the top of the fixed frame 7. The guide rods 20 are slidably connected to the fixed frame 7, and the bottom end of the guide rods 20 is fixedly connected to the top of the lifting frame 9. When the hydraulic rod 8 pushes the lifting frame 9 up and down, the guide rods 20 can limit the lifting frame 9 and improve the stability of the adsorbent sponge 13 when it moves up and down.

[0026] The reciprocating structure 11 includes a mounting frame 111, a drive motor 112, a slide 113, a connecting frame 114, a half gear 115, and a connecting bar 116. The mounting frame 111 is fixed to the bottom of the lifting frame 9, and the lower part of the mounting frame 111 is fixedly connected to the top of the mounting platform 10. The drive motor 112 is fixed to the top of the inner wall of the mounting frame 111. The slide 113 is slidably connected to the top of the mounting platform 10. The connecting frame 114 is fixed to the top of the slide 113, and teeth are provided on both the left and right sides of the inner wall of the connecting frame 114. The half gear 115 is fixed to the bottom end of the output shaft of the drive motor 112, and the half gear 115 meshes with the teeth on the inner wall surface of the connecting frame 114. The connecting bar 116 is fixed to the front and rear sides of the slide 113, and the other side of the connecting bar 116 is connected to the sliding frame 114. The top of the movable plate 12 is fixedly connected, and the surface of the slide table 113 is provided with a limiting groove 18. The bottom of the half gear 115 is fixed with a limiting shaft 19, and the limiting shaft 19 passes through the limiting groove 18 and is rotatably connected to the top of the mounting platform 10. The limiting shaft 19 is slidably connected to the inner wall of the limiting groove 18. After the drive motor 112 is turned on, the output shaft of the drive motor 112 will drive the half gear 115 to rotate, which will cause the connecting frame 114 to drive the slide table 113 to swing back and forth on the surface of the mounting platform 10. The limiting shaft 19 moves inside the limiting groove 18, thereby limiting the entire slide table 113. The connecting bar 116 will then drive the moving plate 12 below to swing left and right, so that the adsorbent sponge 13 can wipe and adsorb the conductive liquid on the surface of the automotive plastic parts on the test platform 4.

[0027] Both sides of the movable plate 12 are fixed with clips, and the adsorption sponge 13 is engaged with the clips. The adsorption sponge 13 is a polyurethane sponge. Polyurethane sponge has good elasticity and softness, which can effectively adsorb conductive liquids. At the same time, it has less friction on the surface of plastic parts and will not cause secondary damage to plastic parts.

[0028] Its working principle is as follows:

[0029] When a tracking test is required on automotive plastic parts, the operator first places the plastic part to be tested on the surface of the central test platform 4 and turns on the dripping device 6, allowing the device to drip conductive liquid onto the surface of the plastic part. Then, the operator activates the electric push rod 14, which moves the energizing device 15 closer to the plastic part, allowing the device to discharge and perform the tracking test. Simultaneously, another plastic part can be placed on the left side of the test platform 4. After the test on the central plastic part is completed, the operator activates the lower motor 31, moving the central test platform 4 to the right side to absorb the sponge 13. Below, the test platform 4 on the left moves to below the dripping device 6. The dripping device 6 and the power supply device 15 continue to conduct the tracking test on the automotive plastic parts. Meanwhile, the hydraulic rod 8 on the right opens, allowing the absorbent sponge 13 to adhere to the surface of the automotive plastic parts below. The drive motor 112 on the surface of the mounting bracket 111 is then turned on, causing the absorbent sponge 13 to move back and forth to wipe the conductive liquid on the surface of the automotive plastic parts. Subsequently, the hydraulic rod 8 controls the absorbent sponge 13 to rise back to its original position. Then, the staff can remove the tested automotive plastic parts for observation and take out new automotive plastic parts to place on the test platform 4 on the right for subsequent testing operations. This completes the tracking test operation on the automotive plastic parts.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
