[0002] In the automotive industry and various emission control systems, the oxygen sensor is a key monitoring component, and the stability and accuracy of its performance are directly related to the vehicle's emission level, fuel economy, and engine operation efficiency. With the continuous growth of automobile production and the increasingly strict emission standards, higher requirements are put forward for the production and detection efficiency and accuracy of oxygen sensors. The traditional manual testing method is not only time-consuming and laborious, but also difficult to ensure the consistency and repeatability of testing, affecting the reliability of test results. Especially when facing the complex structure of multi-channel oxygen sensors, the limitations of manual operation are more obvious. Therefore, developing an automatic pressing device that can efficiently and accurately complete the testing of multi-channel oxygen sensors has become an urgent need in the industry.

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] Please refer to Figures 1-3 , a multi-channel oxygen sensor test automatic pressing device in this embodiment includes an operating table 1. A plurality of mounting holes 3 arranged at equal distances and two waist-shaped holes 5 are opened on the operating table 1. At the same time, sockets 15 equal in number to and corresponding one by one to the mounting holes 3 are also installed, and a fixed seat 12 is installed at the bottom of the operating table 1. A moving adjustment component is installed on the fixed seat 12. The moving end of the moving adjustment component passes through the two waist-shaped holes 5 and is fixed with a pressing plate 2. A groove matching the number of mounting holes 3 is opened on the side of the pressing plate 2 opposite to the mounting holes 3. A sensor 4 is inserted into the socket 15. The head end of the sensor 4 can be inserted into the mounting hole 3. The socket 15 is connected to an external device. A hexagonal seat is provided on the outer side of the head end of the sensor 4. A tail plug is formed at the tail end of the sensor 4, and the tail plug is connected to the socket 15. An air pipe 6 communicating with the mounting hole 3 is installed at the bottom of the operating table 1.

[0016] In the above structure, during detection, the sensor is powered and communicates with peripheral external devices through a socket. The socket can play a role in initially positioning the sensor, and then the sensor can be limited in position and connected to the air pipe through the mounting hole. With the cooperation of the moving adjustment component in the waist-shaped hole, the sensor can be moved forward and backward and up and down, driving the pressing plate to approach the sensor, so that the sensor is limited in the groove. At the same time, the hexagonal seat is located below the groove, and then the sensor is pressed down by moving down, so as to achieve automatic pressing. And through the reset of the pressing plate, it is convenient to disassemble the sensor. At the same time, when the number of sensors increases, through the cooperation of the pressing plate and the groove, when the sensor is pressed, it can also be clearly distinguished, achieving the function of bundling the wires, preventing the sensor wires from being entangled during the detection process and affecting the disassembly efficiency in the later stage. During detection, the detection result can be transmitted to the external device through the sensor and the socket.

[0017] Such as Figures 2-3 , the moving adjustment component includes a horizontal moving end and a vertical moving end installed on the fixed seat 12. The vertical moving end is installed on the horizontal moving end, and the pressing plate 2 is fixed on the vertical moving end. Through the horizontal moving end and the vertical moving end, the pressing plate can be driven to move in two directions of Y and X, so as to facilitate driving the pressing plate to press the sensor and facilitating the removal of the sensor when retracting.

[0018] Among them, the horizontal moving end includes a horizontal cylinder 10 installed on the fixed seat 12. A connecting plate 13 is fixed to the moving end of the horizontal cylinder 10, and the vertical moving end is installed on the connecting plate 13. Through the operation of the horizontal cylinder, the connecting plate can be driven to move forward and backward. Therefore, the pressing plate can be driven to approach the sensor through the vertical moving end, and the pressing plate can be driven to press the sensor in cooperation with the vertical moving end.

[0019] In addition, the vertical moving end includes a top plate 14 fixed to the top of the connecting plate 13. A vertical cylinder 9 is installed on the top of the top plate 14. The ejecting end of the vertical cylinder 9 is fixed with two groups of connecting rods 7 passing through the waist-shaped hole 5 and sleeved with the top plate 14. One group of connecting rods 7 is a pair, and the pressing plate 2 is fixed to the top of the connecting rods 7. When the horizontal moving end drives the pressing plate to move to a suitable position through the vertical moving end, and then through the operation of the vertical cylinder, the pressing plate is driven to press down by the connecting rods to complete the automatic pressing of the sensor. At the same time, the top plate can play a role in limiting the connecting rods and improving the stability of the up and down movement of the connecting rods.

[0020] Combined with the above, a cylinder relay 11 connected to the vertical cylinder 9 and the horizontal cylinder 10 is installed at the bottom of the fixed seat 12. When all the sensors are placed in the mounting holes, the cylinder relay receives the signal and controls the operation of the vertical cylinder and the horizontal cylinder through output transmission, realizing the movement of the pressing plate in the Y and Z directions.

[0021] The working principle of the above embodiments is as follows:

[0022] After the sensors are placed in the mounting holes and sockets, the cylinder relay is activated to open the cylinder and drive the air flow. The horizontal cylinder operates to drive the connecting plate to move. At the same time, the top plate moves along with the connecting plate. Then, in cooperation with the vertical cylinder, it can drive the pressing plate closer to the sensor. Then, the vertical cylinder moves downward to drive the pressing plate to move, automatically pressing the hexagonal seat of the sensor to complete the test of the sensor pressing. After the test is completed, the cylinder relay can drive the horizontal moving end and the vertical moving end to reset, so as to facilitate the removal of the tested sensor and complete a complete test action process.
