[0072] The equipment is divided into thirteen functional stations: automatic loading station for the main body, automatic punching station for wax pills, imaging detection station, automatic quantitative oiling and feeding station for hoses, detection station for the presence or absence of hoses, automatic assembly and loading station for the main body cover sealing sheet, detection station for the presence or absence of the main body cover, external transfer and rotation mechanism for riveted parts, sensor vacuum riveting station, sensor presence or absence detection station, automatic pushing rod loading and vacuum pushing rod insertion station, material picking and sorting station and turntable mechanism.

[0073] The working principle and working process of this specific embodiment:

[0074] Automatic loading station for the main body: the main body with temperature-sensitive wax is placed in a perforated rack. Four perforated dummy trays can be placed in the main body loading stacking bin at a time. When the top tray of materials is transferred to the turntable station fixture in sequence by the three-dimensional mobile loading module. When one tray of materials is finished, the mechanical tray is removed and moved out, and the second batch is moved up to the first tray position.

[0075] Wax ball punching station: the photoelectric detection detects that there is a main body on the station, and the lower supporting cylinder lifts the working tooling on the turntable station (to prevent the turntable from being deformed due to working force), and the blocking cylinder prevents the tooling from descending under pressure. The wax ball punching tooling completes the formation of the inner hole of the wax ball, the blocking cylinder is released, and the lower supporting cylinder retreats to wait for the turntable to transfer the workpiece to the next station.

[0076] The imaging inspection station checks whether there are wax powder and other objects that affect the sealing, or defects such as indentations and concave spots on the step sealing surface of the station body. If it passes normally, it will notify the subsequent process not to act on the workpiece at this station until it is taken out and rejected by the material removal station.

[0077] Automatic quantitative oil filling and feeding station for hoses: The hose is fed into the silicone grease quantitative filling tooling through a vibrating material tray and a linear vibrator. The automatic filling mechanism completes the quantitative filling of silicone grease on the inner wall of the hose, and then it is transferred to the body on the workstation corresponding to the turntable through a robotic arm.

[0078] Hose presence detection station: DDC camera detects the presence of hose and silicone grease. If the requirements are not met, the subsequent process will not act on the workpiece at this station until the workpiece at this station is removed.

[0079] Automatic assembly loading station for body cover and sealing sheet: the body cover and sealing sheet are sent to the corresponding position of the loading tooling through their own vibration plates and direct vibration. The transfer mechanism transfers the sealing sheet and body cover to the workpiece at the corresponding station. The diameter of the material picking rod of the transfer mechanism is slightly larger than the hole diameter of the sealing sheet. The material picking rod passes through the body cover and sealing sheet in turn and then lifts and transfers them. If there is no sealing sheet, the body cover cannot be lifted, which plays a role in preventing mistakes.

[0080] Body cover detection station: The detection mechanism moves downward, and the detection rod presses on the body cover. The detection rod is reset by the spring elasticity. If there is a body cover, the detection rod is forced to move upward for a distance. If there is no body cover, the detection rod does not move. The photoelectric detection mechanism detects the position of the detection rod to determine whether there is a body cover in the workpiece.

[0081] External transfer and rotation mechanism for riveted parts: The products on the turntable tooling are sent to the external riveting station through two claw cylinders, a lifting cylinder and a servo rotation mechanism, and the riveted products at the external riveting station are transferred to the turntable tooling.

[0082] Sensor vacuum riveting station: The riveting tool moves to the vacuum position through the servo electric cylinder to extract the air in the gap between the body and the wax ball, and between the hose and the wax ball, and then the riveting tool continues to move downward to complete the riveting of the product.

[0083] Sensor detection station: The function of this station is to sense in advance whether there are qualified products on the tooling. If so, this station moves to the vacuum pumping and push rod insertion station to vacuum pump and insert the push rod. Otherwise, the vacuum pumping and push rod insertion process is skipped.

[0084] Automatic push rod loading and vacuum push rod insertion station: The push rod is moved to the vacuum push rod insertion tooling in a certain direction through the vibration plate and direct vibration. The vacuum push rod insertion tooling moves downward to seal the upper end of the product to form a closed cavity. After vacuuming, the push rod is inserted into the product.

[0085] Material picking and sorting station: judge whether the product is qualified in advance; the material picking mechanism picks up the material, and the sorting and rejecting cylinder is in action at the same time, the qualified products enter the qualified product channel, and the unqualified products enter the waste box.

[0086] It realizes fully automatic assembly and production of sensors, adds detection and error prevention before each workstation, and automatic rejection of waste products, which improves product quality; good human-machine interface and easy operation; high degree of automation, reduces labor intensity and saves costs; anti-noise device reduces noise and improves employee comfort; the equipment is compact and occupies a small area; the environment is neat and clean.
