Description

Technical Field

[0001] This invention relates to the field of lock component manufacturing technology, specifically to an automatic assembly equipment for key unlocking plates and handles. Background Technology

[0002] Pin tumbler lock unlocking keys are commonly used tools in the field of mechanical unlocking, widely applied in scenarios such as spare lock cylinders for car doors and home door locks. Their assembly quality directly affects unlocking reliability and user experience. (See attached document for details.) Figure 1 , 2 The key shown consists of a metal unlocking plate (one end of which has a toothed unlocking structure adapted to the pin tumbler lock cylinder) and a plastic handle (providing a comfortable grip). A groove is machined inside the plastic handle to cover the other end of the unlocking plate. Both the end of the plastic handle and the end of the unlocking plate have through holes. A screw passes through the through holes and engages with a nut threaded into the screw, thus securing the unlocking plate to the plastic handle. This key, through its toothed structure adapted to the internal structure of the pin tumbler lock cylinder, enables manual opening and closing. The overall structure is simple and robust, meeting the reliability requirements for emergency or daily unlocking.

This design realizes the synchronous automatic offline of the finished key and the matched lock cylinder, forming a production closed loop.

[0037] The working principle of the device is that the main driving source drives the rotating disc d to rotate intermittently, and drives the clamping tool a on it to pass through each station in turn, and the automatic circulation assembly is completed through the cooperation of each component. First, in the unlocking piece feeding station d2, the key unlocking piece is placed into the lock piece placing groove a11 of the positioning product seat a1 by artificial or mechanical hand, and the lock matched with the key is placed into the lock placing groove a12. Then the rotating disc d drives the clamping tool a to move to the handle feeding station d4, the handle feeding assembly g takes out the handle from the handle disc, and after transfer and posture adjustment, the handle is accurately placed on the movable product seat a2 by the handle transfer mechanism g3, and is clamped by the first clamping block a22 of the first finger cylinder a21. In the screw feeding station d3, the screw feeding assembly f sorts and transports the single screw sorted from the screw vibration disc f16, and the fourth finger cylinder f21 clamps and transfers the screw, and finally the screw is placed on the upper end of the accessory pipe a6 of the clamping tool a and is fixed by the magnet a62. Subsequently, the clamping tool a flows to the hole alignment station d5. At this station, the pressing block h1 of the pressing assembly h is pressed down to press and fix the unlocking piece. At the same time, the fourth cylinder j1 of the first pull-down mechanism j acts, the second L-shaped pull-down block j2 pulls the first L-shaped pull-down block a47, the top rod a41 moves downward, and the end hole of the unlocking piece is withdrawn. Then, the handle moving cylinder i fixed on the rack e acts, the output end of the handle moving cylinder i pushes the intermittent driving rod a261 on the movable product seat a2, overcomes the elastic force of the first spring a32, drives the movable product seat a2 to carry the handle to approach the positioning product seat a1, until the end of the unlocking piece is inserted into the corresponding groove of the handle, and the hole of the unlocking piece is aligned with the end of the handle. At this time, the top rod a41 is repositioned under the action of the second spring a44 after the first pull-down mechanism j is released. This series of actions ensures that the hole of the unlocking piece is accurately aligned with the end of the handle, and lays a foundation for subsequent assembly. The workpiece after alignment flows to the nut assembly station d6. At this time, the buffer reset cylinder n extends and supports the intermittent driving rod a261 to provide support for the movable product seat a2. The nut feeding assembly b starts to work: the nut sorting feeding mechanism b1 feeds the single nut to the nut discharge block b15, the third finger cylinder b22 of the nut transfer assembly b2 clamps the nut, and through horizontal and vertical movement, the nut is placed on the top end of the top rod a41 which has been reset. Then, the first cylinder b26 drives the cap pressing rod b24 to press down, and the pull-down cylinder m1 of the second pull-down mechanism m pulls the first L-shaped pull-down block a47 through the third L-shaped pull-down block m2, so that the top rod a41 with the nut moves downward synchronously, the nut is stably pressed into the end hole of the aligned unlocking piece and handle, and the pre-assembly is completed. After the pressing assembly is completed, the buffer reset cylinder n slowly retracts, and the movable product seat a2 stably retreats to the initial position to prevent the nut from being shaken off due to impact. Then, the workpiece enters the screw assembly station d7.First, the seventh cylinder a56 of the accessory lifting mechanism a5 drives the lifting sleeve a55 to rise, lifting the accessory lifting seat a51, overcoming the elastic force of the third spring a53, driving the accessory tube a6 and the screw inside to rise, making the screw accurately inserted into the handle end hole with a pre-installed cap, and initially contacting with the cap. Subsequently, the fifth cylinder c2 drives the cap pressing block c1 to move down, pressing the cap to prevent it from rotating. At the same time, the sixth cylinder c38 of the spin riveting mechanism c3 pushes the lifting rod c34 to rise, and the lifting force is transmitted to the lifting plate c33 through the flexible pressure mechanism, so that the ejector pin c31 rotates and rises under the drive of the motor c32. The ejector pin c31 passes through the ejector pin hole a63 of the accessory tube a6 and is inserted into the screw slot of the screw head. Under the joint action of rotation and axial lifting force, the screw is smoothly screwed into the cap until the predetermined torque or depth is reached. The photoelectric sensing assembly e3 detects the position of the detection plate c35 on the lifting plate c33 to determine whether the screw is tightened in place. Finally, the finished product is transferred to the finished product discharge station d8 with the turntable d. The third belt of the discharging assembly k drives the fourth transverse moving plate k3 to move to the corresponding position, and the discharging lifting cylinder k2 drives the discharging plate k1 to descend. The sixth clamp block k7 of the sixth finger cylinder k5 clamps the assembled key, and the seventh clamp block k8 of the seventh finger cylinder k6 clamps the matching lock cylinder pre-placed in the lock placing groove a12. After clamping, the discharging plate k1 rises and moves transversely above the collection device, releases the clamp block, and releases the key and lock cylinder respectively, completing the automatic offline of the finished product. Then, each tooling and mechanism resets, the turntable d continues to rotate, and the next working cycle begins.
