Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a sensor sealing detection device for automotive parts, including a support guide 7. A servo motor 1 is disposed at the center of the front end face of the support guide 7, and a bidirectional lead screw 9 is disposed at the output end of the servo motor 1. Two sets of linear slide rails 6 are disposed on the upper end face of the support guide 7, and ball bearing slides 8 are slidably engaged on the upper end face of each of the two sets of linear slide rails 6.

[0023] Locking device 3 is fixedly installed at the middle of the upper end face of the support guide 7, and sensor housing 10 is provided on the inner end face of locking device 3. Locking device 3 is used to lock and limit the sensor housing 10 to be tested.

[0024] Fixed bracket 4 is fixedly installed on the upper end face of the ball slide 8 located at the front. A high-pressure gas guide pipe 5 is provided at the rear of the fixed bracket 4. The high-pressure gas guide pipe 5 is used to input the high-pressure gas to be detected into the sensor housing 10.

[0025] The detection device 2 is fixedly installed on the upper end face of the ball bearing slide 8 located at the rear, and the detection device 2 is used to detect the sealing performance inside the sensor housing 10.

[0026] like Figure 3The detection device 2 includes an alignment guide seat 21, a sealing base 25 is provided at the center of the side end face of the alignment guide seat 21, and a pressure sensor 22 for detection is provided at the center of the side end face of the sealing base 25. A spring guide shaft 23 is provided at the center of the side end face of the pressure sensor 22, and a sealing plate 24 is provided at the side end face of the spring guide shaft 23.

[0027] like Figure 4 The locking device 3 includes a wide air gripper 33. The side end face of the wide air gripper 33 is provided with two sets of guide slides 32, and the top of each set of guide slides 32 is provided with an alignment clamp 31, which can effectively improve the stability of locking the sensor housing 10 and improve the stability of detection.

[0028] like Figure 1 Both sets of ball bearing slides 8 are slidably connected to the inner end face of the support guide seat 7 by a bidirectional lead screw 9. Under the threaded guidance of the bidirectional lead screw 9, the two sets of ball bearing slides 8 can perform centripetal and centrifugal displacement, which can facilitate subsequent testing of sensor housings 10 of different lengths and models.

[0029] like Figure 2 The high-pressure gas guide tube 5, the sealing base 25, and the sensor housing 10 are coaxially arranged. The output end of the high-pressure gas guide tube 5 is sealed and fitted to the inner wall of the sensor housing 10, which can effectively improve the stability of the subsequent high-pressure gas guide tube 5 in delivering the detection gas inside the sensor housing 10.

[0030] like Figure 2 The alignment guide seat 21 is sealed and snapped into the inner wall of the sensor housing 10 through the sealing base 25. When the sealing performance of the inside of the sensor housing 10 is tested, the sealing base 25 can seal the end of the sensor housing 10 to be tested to prevent gas leakage during the test.

[0031] The sealing plate 24 is connected to the inner wall of the sensor housing 10 in a sealed sliding connection. The sliding of the sealing plate 24 inside the sensor housing 10 can quickly and stably detect whether there is gas leakage inside the sensor housing 10, and thus quickly and accurately determine the sealing performance of the sensor housing 10.

[0032] Working principle: Before testing the sealing performance of the sensor housing 10, the operator can position the robotic arm module to be loaded onto the side of the support guide 7 for easy and quick loading. During testing, the external robotic arm module positions the sensor housing 10 above the locking device 3. At this time, the wide gripper 33 is activated, opening the two sets of alignment clamps 31. The robotic arm module moves the sensor housing 10 downwards and positions it between the two sets of alignment clamps 31. Subsequently, the wide gripper 33 drives the two sets of alignment clamps 31 to lock the sensor housing 10 via the guide slide 32. Then, the servo motor 1 is activated, and the servo motor 1 can drive the two sets of alignment clamps 31 to lock the sensor housing 10 via bidirectional... The lead screw 9 drives two sets of ball bearing slides 8 to move toward the sensor housing 10. At this time, the high-pressure gas pipe 5 can be connected to the inside of the sensor housing 10, and the sealing plate 24 can be introduced into the inside of the sensor housing 10. The sealing base 25 then seals one end of the sensor housing 10. Subsequently, the high-pressure gas pipe 5 conducts external high-pressure gas through it. After completion, the gas is locked, so that the pressure inside the sensor housing 10 remains constant. At the same time, the sealing plate 24 moves backward after receiving pressure, and the pressure sensor 22 can read the pressure reading. When the sealing of the sensor housing 10 is poor, the reading of the pressure sensor 22 will gradually decrease, thus completing the detection operation.

[0033] 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 can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
