Description

Technical Field

[0001] This utility model relates to the field of sealing strip detection devices, specifically a vehicle door frame sealing strip detection device. Background Technology

[0002] Automotive sealing strips fill various gaps and crevices between vehicle body components, providing functions such as shock absorption, waterproofing, dustproofing, sound insulation, and decoration. They enhance driving comfort and protect the vehicle body. After the automotive rubber door frame sealing strips are manufactured, their overall length needs to be measured. This is generally done using specialized gauges. Because rubber products have characteristics such as a large size range, easy stretching and deformation, and lateral extension, attention must be paid to the placement and normal unfolding state of the sealing strip during inspection. Traditionally, sealing strip length is measured manually by personnel holding a roller and measuring the length by the number of rotations. However, this method is often affected by factors such as the rolling angle and inertia of the measuring personnel, resulting in significant deviations and making it impossible to accurately measure whether the sealing strip is within the allowable tolerance range.

[0025] In practical use: A fixed disc 41 is installed at the bottom of the surface of panel 2, and a movable disc 42 is movably installed at the top of the surface of panel 2. During measurement, the movable disc 42 is controlled to move closer to the fixed disc 41, and the sealing strip 43 is wrapped around the surfaces of the fixed disc 41 and the movable disc 42. At this time, the movable disc 42 is controlled to move upward so that the sealing strip 43 is in a straight state. At this time, the measuring ruler 44 installed at the bottom of the movable disc 42 corresponds to the scale line 45 engraved on the surface of panel 2. When the position of the measuring ruler 44 and the corresponding position of the scale line 45 are within the allowable tolerance range, the length of the sealing strip 43 is qualified; otherwise, it is unqualified.
