[0063] Step S1: The tilt sensor PCBA is transported to the side of the first module 100 via the feeding device 430. The first robot arm 110 picks up the tilt sensor PCBA and places it on the mounting base 121 of the power-on detection device 120.

[0064] Step S2: The mounting base driving mechanism 123 drives the mounting base 121 to move below the support frame 122, and the test board driving mechanism 125 drives the test board 124 to move downward, so that the test probe 126 extends into the preset break point on the PCBA of the tilt sensor for power-on detection.

[0065] Step S3: The first robotic arm 110 transfers the PCBA of the tilt sensor to the positioning seat 131 of the breakpoint welding device 130. The positioning seat driving mechanism 132 drives the positioning seat 131 to move below the welding mechanism 133. The welding driving mechanism 134 drives the welding mechanism 133 to move downward to weld the connection at the preset breakpoint on the PCBA of the tilt sensor.

[0066] Step S4: The rotary transfer mechanism 146 picks up the top cover of the tilt sensor transported by the top cover feeding mechanism 142 and places it on the mounting platform 141; the assembly mechanism 144 picks up the light guide column of the tilt sensor from the light guide column feeding mechanism 143 and transports it to the mounting platform 141, assembling it together with the top cover of the tilt sensor on the mounting platform 141; the horizontal transfer mechanism 146 transports the top cover of the tilt sensor to the waiting mechanism 145; the first robot arm 110 transfers the PCBA of the tilt sensor to the waiting mechanism 145 and assembles it together with the top cover of the tilt sensor to form a semi-finished tilt sensor; the first robot arm 110 transfers the semi-finished tilt sensor to the first conveying device 410.

[0067] Step S5: The second robotic arm 210 grabs the tilt sensor semi-finished product on the first conveying device 410 and places it on the closing mechanism 224; the bottom cover grabbing mechanism 223 grabs the paper sheet on the paper sheet holder 225 and places it in the bottom cover of the tilt sensor, and then grabs the bottom cover of the tilt sensor and places it in the closing mechanism 224; the closing mechanism 224 closes, so that the tilt sensor semi-finished product and the bottom cover placed in the closing mechanism 224 are assembled together to form the tilt sensor finished product.

[0068] Step S6: The second robotic arm 210 grasps the tilt sensor finished product and places it on the welding table 233 of the ultrasonic welding device 230. The ultrasonic welding head 232 welds and fixes the tilt sensor finished product. The second robotic arm 210 grasps the tilt sensor finished product and places it on the second conveying device 400.

[0069] Step S7: The third robotic arm 310 picks up the tilt sensor finished product from the second conveying device 400 and places it on the fixed base 321 of the airtightness testing device 320. The sealing base driving mechanism 323 drives the sealing base 322 to press down, sealing the tilt sensor finished product in the test chamber 325. The air intake component 324 inflates the test chamber 325 to determine the degree of welding firmness of the tilt sensor finished product.

[0070] Step S8: The third robotic arm 310 picks up the finished tilt sensor from the fixed base 321 and places it on the rotating frame 332. The rotating frame drive mechanism 333 drives the rotating frame 332 to tilt. The button cylinder group 334 presses the button of the tilt sensor to test whether the tilt sensor is functioning properly.

[0071] Step S9: The third robotic arm 310 picks up the finished tilt sensor from the fixed base 321 and places it at a predetermined position below the laser marking device 340. The laser marking device 340 prints label information on the finished tilt sensor. The third robotic arm 310 picks up the finished tilt sensor and places it on the discharge device 440.
