[0053] Working principle of the pin needle mechanism

[0054] (a) Parting die unit:

[0055] First step: The parting lower mold moves along the feeding track to the feeding position, and the lock shell to be processed is placed in the profiled positioning groove. The parting lower mold moves with the lock shell into the jig seat to complete the feeding.

[0056] Second step: When it is detected that the plastic shell / parting lower mold moves to the die position, the hydraulic cylinder drives the parting upper mold to press down to combine with the parting lower mold, so that the punch and the punching hole cooperate to punch the lock shell. The waste after punching falls from the material falling port on the parting lower mold and the table plate. At this time, the ejection spring column is in a compressed state.

[0057] Third step: After the punching is completed, the upper and lower molds remain in the combined state and wait for the pin needle.

[0058] Fourth step: after the pin is inserted, the hydraulic cylinder drives the split upper mold to rise (if the split upper mold does not rise due to loosening of the hydraulic cylinder, the stripper spring column will extend and reset under the action of its own elastic force, and drive the split upper mold to rise), the split lower mold drives the finished product to move to the discharging position.

[0059] (b) Pin insertion unit

[0060] First step: the left and right groups of material belt feeding units perform feeding: install the full material tray on the feeding rack, pull out the material belt and lay it along the material belt conveyor, then pass the material belt end through the material pressing roller and extend it into the feeding channel of the cutting unit, turn on the paper winding motor and the rotating motor to start feeding;

[0061] Second step: when the material belt is detected to move to the cutting position, the cutter cylinder drives the upper cutter body to descend, so that the upper cutter body cooperates with the lower cutter body to cut the pin from the material belt, and the excess waste falls from the lower discharging port;

[0062] Third step: the left and right groups of servo modules are started, the servo modules first drive a material taking clamp assembly to move to the material taking position, the driving cylinder drives the material taking clamp assembly to open and the telescopic cylinder drives the material taking clamp assembly to extend, one material taking clamp assembly takes 8 pins, after taking, the telescopic cylinder retracts, the servo module drives another material taking clamp assembly to take material; when both material taking clamp assemblies have finished taking material, the left and right groups of servo modules drive the two material taking clamp assemblies to move to the pin insertion position;

[0063] Third step: the left and right groups of servo modules each drive two material taking clamp assemblies to move to the pin insertion position, the telescopic cylinder drives four material taking clamp assemblies to extend, so as to insert the pins into the insertion holes on the lock shells, one time can insert four lock shells, and 8 pins are inserted into one lock shell at the same time.

[0064] The automatic pin insertion mechanism for the electronic lock has the following advantages:

[0065] 1. The automatic feeding, pin insertion and other operations are realized, the production precision and stability are improved, and the production needs are met;

[0066] 2. The synchronous splitting and pin insertion of 4PCS materials can be realized, the production rhythm is improved, and the production efficiency and capacity are improved;

[0067] 3. The device space is reasonably utilized, the space is saved, the whole mechanism structure is small and exquisite, and the practicality is strong and the cost is low.
