Description

Technical Field

[0001] The utility model relates to the technical field of wiper rubber strip life detection, in particular to a glass wiper rubber strip life detection device. Background Art

[0002] During use, the windshield wiper will repeatedly rub against the rubber strips. The high-frequency squeezing and repeated scraping process will cause the rubber strips to be damaged by friction. The wear resistance of the rubber strips is related to the scraping effect of the rubber strips. The rubber strips are listed as the core components of the windshield wiper. In actual use, people usually use handheld wipers to clean the glass. Due to factors such as inconsistent scraping angles, uneven scraping force, uncontrollable scraping frequency and uncontrollable scraping stroke, the durability of the windshield wiper rubber strips will vary. Some of the rubber strips are asymmetrical or have worn teeth, which can easily result in the glass not being cleaned thoroughly. Existing wiper rubber strips generally pass a simple manual glass scraping test before leaving the factory. This test method cannot meet people's usage needs, and there are errors caused by human factors in the test, resulting in inconsistent quality of wiper rubber strips. In addition, the detergent water cannot be recycled during the manual scraping process, resulting in a waste of water resources.

[0033] Specific implementation methods of the utility model: The present invention adopts a clamp to fix the glass wiper, adopts a photoelectric encoder to measure the scraping angle and angle data collection, ensures that the glass wiper scrapes stably and accurately, adopts a water pump to pump water and spray, thereby simulating the water environment on the glass surface, and the water in the spraying process flows back to the water tank through the water guide groove to realize water circulation. A mobile cylinder is used to realize the forward and backward movement of the glass wiper, and a lifting cylinder is used to move up and down.

[0034] Among them, the water tank is filled with detergent water, and the water pump draws the detergent water out of the water tank along the suction pipe, and draws the detergent water to the upper nozzle along the outlet pipe.

The cylinder limit posts (limiters) at the upper and lower ends are used to control the stroke of the up and down moving cylinders, thereby controlling the scraping distance of the windshield wiper. In addition, the pressure sensor is connected to the four sensing axes. When the windshield wiper contacts the glass plate, it presses the four sensing axes, which can be used to monitor and collect the pressure during the scraping process.

[0035] Among them, the principle of single scraping action: after the nozzle sprays water, the cylinder moves forward to make the glass wiper contact with the product, and the cylinder moves downward to make the glass wiper wipe. After wiping, the cylinder moves backward to make the glass wiper separate from the glass surface. The equipment also has a counting function that can record the number of tests and set the number of tests. During the test, information such as the number of tests, test angle, scraping force, and scraping frequency are collected and recorded on the display screen.
