Abstract
Description
Technical Field
[0001] The present application relates to the technical field of automobile parts testing equipment, and in particular to a water tank rubber strip testing device. Background Art
[0002] In the automobile manufacturing process, the gutter is an automobile component, usually a drainage channel designed on the body or door, which effectively guides rainwater or water used to wash the vehicle to be discharged from a specific outlet, avoiding water accumulation on the surface or inside of the vehicle body, and reducing the risk of corrosion and rust. The rubber strip is an important component of the gutter, and the accuracy of the adhesive position of the rubber strip on the gutter is directly related to the sealing and ride comfort of the car.
[0003] The accuracy of the adhesive strip adhesion directly affects the sealing of the water channel. If the adhesive strip is not adhered accurately, it may cause water leakage, thus affecting the normal use and function of the water channel; inaccurate adhesion may also cause the adhesive strip to fall off during use, thus affecting the overall structural safety of the diversion water channel; and if the adhesive strip is not adhered accurately, it may need to be replaced or repaired frequently, which will increase maintenance costs and workload, affecting the economic benefits and service life of the water channel.
[0004] In the prior art, the position of the rubber strip on the water flow trough is usually detected by using a glue sensor. This process is divided into two steps: teaching and measurement. The teaching process uses prior information to measure the position and width of the rubber strip as teaching information in the measurement process. The specific method is to click the skeleton points at the center of the rubber strip. These skeleton points are located on the center line of the rubber strip, and curve fitting is performed through these points to generate a smooth curve. Then, a model for detecting the edge of the rubber strip is generated based on the points on the curve, and then the width, position, grayscale and other information of the rubber strip are used to detect the edge of the rubber strip. This method has high requirements on the accuracy of manually clicking the skeleton points. In theory, the points need to be in the center of the rubber strip to ensure the accuracy of the detection. Through this technology, accurate detection of the position of the rubber strip on the water flow trough can be achieved to ensure the accuracy of its installation and sealing performance. However, the operation process takes too long, which greatly reduces the detection efficiency of the rubber strip of the water flow trough. Utility Model Content
[0005] In order to improve the detection efficiency of water trough rubber strips, the present application provides a water trough rubber strip detection device.
[0006] The present application provides a water tank rubber strip detection device that adopts the following technical solution:
[0007] A water trough rubber strip detection device comprises a workbench, a support platform is arranged on the workbench, and a positioning piece for positioning the water trough is arranged on the support platform, a plurality of support seats for supporting the water trough are distributed on the workbench along the length direction of the water trough, a control box is also arranged on the workbench, a laser displacement sensor is arranged on one side of the workbench located at the adhesive part of the rubber strip on the water trough, the laser of the laser displacement sensor is aimed at the side wall of the rubber strip, and the laser displacement sensor is electrically connected to the control box.
[0008] By adopting the above technical solution, when using this detection device, first place the water trough on the platform and accurately position it through the positioning piece. Then, start the laser displacement sensor through the control box, and the laser displacement sensor emits a laser to align the side wall of the rubber strip for measurement. The measurement data is transmitted to the control box in real time. After processing and analysis, the operator can quickly determine whether the position of the rubber strip is accurate, thereby completing the entire detection process. Due to the use of laser displacement sensors for non-contact rapid measurement, this detection device significantly improves the detection efficiency of the rubber strip of the water trough.
[0009] Optionally, a through hole is provided on the water flow trough, and the positioning member is a positioning pin which vertically penetrates the through hole, and the positioning pin is plug-fitted into the through hole. When the water flow trough is sleeved on the positioning pin, the bottom wall of the water flow trough is supported on the support platform.
[0010] By adopting the above-mentioned technical scheme, utilizing the plug-in fit between the positioning pin and the through hole on the water flow trough, the stability of the water flow trough during the detection process can be further ensured to prevent it from shifting or rotating, thereby improving the accuracy of the detection; and when the water flow trough is mounted on the positioning pin, the bottom wall of the water flow trough is supported on the base, thereby achieving stable support of the water flow trough.
[0011] Optionally, a limiting member is provided on the workbench at a side of the water flow trough away from the laser displacement sensor, and the limiting member includes a support rod arranged vertically, a limiting plate hinged toward one side of the water flow trough, and a torsion spring hinge arranged at the hinge between the support rod and the limiting plate. The limiting plate matches the shape of the water flow trough and is pressed against the water flow trough on one side of the rubber strip.
[0012] By adopting the above technical solution, the limiting plate always has a tendency to rotate toward one side of the water trough under the action of the torsion spring hinge, so that it can be closely attached to the side wall of the water trough to limit it. This structure can further increase the stability of the water trough during the detection process, prevent the water trough from moving due to external forces, and thus improve the reliability of the detection results.
[0013] Optionally, a clamp is provided corresponding to each support seat on the workbench, and each of the clamps includes a corner cylinder vertically arranged on the workbench and a pressure rod arranged at the end of the rotating rod on the corner cylinder, and the pressure rod is arranged to match the groove shape of the water flow trough. The corner cylinder is electrically connected to the control box. When the clamp positions the water flow trough, the bottom wall of the pressure rod contacts the side wall of the water flow trough and limits the water flow trough between the support seat and the pressure rod.
[0014] By adopting the above technical solution, when the fixture positions the water flow channel, the bottom wall of the pressure rod contacts the side wall of the water flow channel, limiting the water flow channel between the support seat and the pressure rod, further improving the stability of the water flow channel during the detection process.
[0015] Optionally, the pressure rod and the corner cylinder are detachably arranged.
[0016] By adopting the above technical solution, the detachable setting between the pressure rod and the corner cylinder enables the fixture to adapt to water troughs of different specifications, thereby improving the versatility of the detection device. When the specifications of the water trough need to be changed, only the corresponding pressure rod needs to be replaced without replacing the entire fixture, thereby reducing costs and improving operational convenience.
[0017] Optionally, a protective cover is provided on the workbench corresponding to the laser displacement sensor, and a window for laser emission is provided on the side of the protective cover facing the rubber strip.
[0018] By adopting the above technical solution, the setting of the protective cover can protect the laser displacement sensor from interference and damage from the external environment and extend its service life. At the same time, the opening of the window can ensure that the laser can be normally emitted and measure the rubber strip, and the detection effect will not be affected by the shielding of the protective cover.
[0019] Optionally, a guide shaft is vertically arranged inside the protective cover, the laser displacement sensor is slidably sleeved on the guide shaft, and a bolt clamp for clamping the guide shaft is arranged on the housing of the laser displacement sensor.
[0020] By adopting the above technical solution, the laser displacement sensor can slide on the guide shaft to adjust the height, and the position of the laser displacement sensor can be adjusted according to actual needs, further improving the flexibility and accuracy of detection.
[0021] Optionally, a circular chamfer is provided on the top side wall of the locating pin.
[0022] By adopting the above technical solution, the setting of the arc chamfer makes it easy to quickly put the through hole on the water trough on the positioning pin along the guide of the arc chamfer, and when the side top wall of the positioning pin hits the side wall of the water trough, it can reduce the possibility of scratches and wear on the side wall of the water trough through hole due to sharp edges, thereby improving the integrity of the water trough after inspection.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. When using this detection device, first place the water trough on the platform and accurately position it using the positioning piece. Then, start the laser displacement sensor through the control box, and the laser displacement sensor emits a laser to align the side wall of the rubber strip for measurement. The measurement data is transmitted to the control box in real time. After processing and analysis, the operator can quickly determine whether the position of the rubber strip is accurate, thereby completing the entire detection process. Due to the use of laser displacement sensors for non-contact rapid measurement, this detection device significantly improves the detection efficiency of the water trough rubber strip;
[0025] 2. The plug-in fit between the positioning pin and the through hole on the water trough can further ensure the stability of the water trough during the detection process, prevent it from shifting or rotating, thereby improving the accuracy of the detection. When the water trough is sleeved on the positioning pin, the bottom wall of the water trough is supported on the support platform, which can achieve stable support of the water trough;
[0026] 3. The limit plate always has a tendency to rotate toward one side of the water trough under the action of the torsion spring hinge, so that it can fit tightly against the side wall of the water trough to limit it. This structure can further increase the stability of the water trough during the detection process, prevent the water trough from moving due to external forces, and thus improve the reliability of the detection results.
