There are two inclined tongue plate clamping claws 311, which are spaced apart. The inclined tongue plate vibrator 34 vibrates the inclined tongue plate to the first feeding guide plate 36. The first direct vibration feeder 35 feeds the inclined tongue plate in the first feeding guide plate 36 to the first receiving seat 37. Then, the second inclined tongue plate cylinder 39 drives the inclined tongue plate clamping cylinder 310 to move down. After reaching the designated position, the inclined tongue plate clamping cylinder 310 drives the two inclined tongue plate clamping claws 311 to move and complete the clamping of the inclined tongue plate. Then, the second inclined tongue plate cylinder 39 drives the inclined tongue plate to move up. Then, the first inclined tongue plate cylinder 38 drives the inclined tongue plate to move above the fixture. Then, the second inclined tongue plate cylinder 39 drives the inclined tongue plate to move down onto the fixture. Then, the inclined tongue plate clamping cylinder 310 drives the two inclined tongue plate clamping claws 311 to release the clamping of the inclined tongue plate. In this way, the feeding of the inclined tongue plate is completed. Then, it resets and starts feeding the next inclined tongue plate.

One end of the tongue-buffering stop has a blocking part, which is provided with an upper inclined platform and a lower inclined platform. When the tongue-buffering plate with the spring is pushed to... When the tongue is in the tongue receiving groove, the tongue will press against the tongue stop by the lower inclined platform. The tongue stop is moved, and the tongue enters the tongue receiving groove. Due to the reset force of the tongue stop spring, the tongue stop is reset, and the stop part completes the blocking of the tongue. Then, the first tongue feeding cylinder 53 moves up, driving the tongue with spring to move up. The tongue moving module 52 moves, driving the tongue with spring to move above the tongue plate. Then, the first tongue feeding cylinder 53 moves down, driving the tongue with spring to move down, so that the bottom end of the tongue feeding seat 58 abuts against the tongue plate. Then, the second tongue feeding cylinder 57 works, driving the tongue feeding column 510 to move and push the tongue with spring out of the tongue receiving groove and place it on the tongue plate. Then, due to the reset force of the spring, the tongue is pushed and moved until the spring is reset. At this time, part of the tongue is stuck by the tongue plate, thus completing the assembly.

When the corrected door lock parts are transferred by the turntable mechanism 20 to the area below the spring detection mechanism 70, the spring detection cylinder 72 operates, causing the spring detection seat 73 to move downwards, which in turn causes the detection column 74 and the detection pressure column 75 to move downwards. When they come into contact with the latch, due to the setting of the detection spring, the detection bearing 76 will press the latch tightly. Since it is pressed by the detection bearing 76, the detection column 74 continues to move downwards, and its tilting platform will cause the latch to move relative to the detection bearing 76. The movement of the latch will compress the spring, thereby detecting whether there is a spring and whether the spring is in normal condition. After the detection is completed, it can be reset, and then the turntable mechanism 20 will drive it to the unloading mechanism 80.

The qualified product discharge channel and the defective product discharge channel are both connected to the main discharge channel. One end of the unloading rotary column 89 is located at the connection between the qualified product discharge channel and the defective product discharge channel. When the inspected door lock component moves to the unloading mechanism 80 via the turntable mechanism 20, the second unloading cylinder 84 operates, causing the unloading clamping cylinder 85 to move downwards until the unloading clamping claw 86 can clamp the door lock component. Then, the unloading clamping cylinder 85 operates, causing the two unloading clamping claws 86 to complete the clamping of the door lock component. Then, the second unloading cylinder 84 operates, causing the door lock component to move upwards. Then, the first unloading cylinder 83 operates, causing the door lock component to move above the feeding end of the unloading bin 87. Then, the second unloading cylinder 84 operates, causing the door lock component to move downwards. When it reaches the unloading point, the unloading clamping cylinder 85 operates, causing the unloading clamping claws 86 to release. The door lock parts are clamped and fall into the unloading bin. Then, the clamping and unloading of the next door lock part is performed. After the door lock parts fall into the unloading bin, the spring detection mechanism 70 can transmit the detection information to the unloading mechanism. If it is a qualified product, the unloading rotary cylinder 88 works to drive the unloading rotary column 89 to rotate, thereby driving the unloading baffle 810 to cover the defective product discharge channel. The door lock parts are unloaded through the qualified product discharge channel. If it is a defective product, the unloading rotary cylinder 88 works to drive the unloading rotary column 89 to rotate, thereby driving the unloading baffle 810 to cover the qualified product discharge channel. The door lock parts are unloaded through the defective product discharge channel.
