TO-251/252-4R/6R Automatic Lead-Forming System


Feeding section: Utilizes a dual‑magazine vertical‑ejection feeding system, enabling continuous operation during magazine changes. Material-handling section: The product is picked up by a gripper from the magazine and placed onto the conveyor track. Feed section: A stepper motor‑driven feeding mechanism accurately positions the product, and the system triggers a card‑presence alarm when a card is detected. Push‑and‑guide mechanism: A toothed conveyor rod advances the product; it engages the blister pack from beneath and feeds it into the mold for rib cutting, forming, and separation. Finally, a pusher tooth ejects the product to the right onto an inclined platform, where the tube‑insertion operation is performed. Power section: A servo motor and a reducer drive the cam mechanism for punching and cutting. Material receiving section: Two receiving methods are available—bulk and tube‑based. In the tube‑based mode, empty tubes are stacked at the rear and placed in the empty‑tube tray; a tube‑feeding mechanism then conveys these empty tubes to the loading station to perform the tube‑loading operation, after which the loaded tubes are pushed into the front‑mounted tube box.

Accessories


Extensive experience in equipment development and application enables us to deliver tailored solutions. The machining equipment ensures the dimensional accuracy of the components. Rational selection of imported materials enhances service life and stability. Advanced process management ensures timeliness.

Automatic Film-Loading/Batch-Processing System (Grab-and-Load Type)


Material is fed via a magazine; the wafers are first conveyed by a roller-driven belt along the track to the robotic arm’s gripping position, after which the arm places the wafers onto the preheating station. The robotic arm’s base is integrally cast, providing exceptionally high stability. Its drive components incorporate servo motors, high-precision ball screws, and linear guides to ensure precise positioning in repetitive motions. The track is equipped with material‑leakage detection and anti‑reverse detection functions, providing both leakage alarms and reverse‑material‑piece alarms. Based on customer requirements, an automatic dough‑feeding function can be added to the existing equipment, enabling a single machine to perform multiple tasks—namely, sheet dispensing and dough feeding.

Automatic Scheduling/Material-Block System (Pull-Strip Type)


Material is fed via a hopper; after an operator places the hopper onto the lifting platform, the platform lowers to the pusher‑plate height, whereupon the motor drives the lead‑screw mechanism to transfer the product from the hopper onto the conveyor track. Once the track detects a product, the servo motor drives the ball-screw module to position the workpiece. The transmission system employs a servo motor, high-precision ball screws, and linear rails to ensure precise positioning in repetitive motions. The track is equipped with detection functions for misalignment, material leakage, and push‑overload conditions. Based on customer requirements, an automatic dough‑feeding function can be added to the existing equipment, enabling a single machine to perform multiple tasks—namely, sheet‑cutting and dough‑feeding.

AUTO T/F-HS Automatic High-Speed Groove-Cutting and Forming System


Feeding section: Employs a dual‑magazine, vertically lifting feeding system that enables continuous operation during magazine changes. Material‑handling section: The product is picked from the magazine by a gripper, undergoes visual inspection for orientation detection, and is sorted—OK units are conveyed to the output track, while NG units are diverted to the reject bin. Feed section: A servo motor drives a conveyor belt to accurately position the product. Conveyor and guide‑rail assembly: After the product is pressed firmly by pressure rollers, it is conveyed step by step by roller wheels. First, it undergoes a glue‑deficiency inspection on the track; if defective, the machine stops and triggers an alarm, while conforming units are fed into the die for punching. The finished products then drop from beneath the die into the collection tray. Powertrain: servo motor + gearbox + cam mechanism. Boxing section: Two product boxes are positioned beneath the mold. When the left-hand box is full, the machine automatically switches to the right-hand box, enabling continuous operation without stopping to change boxes. Compatibility: The equipment is compatible with SOT and SOD products ranging from 20 to 100 mm in width. A vision system matches the product type to the appropriate mold and automatically retrieves pre‑set operating parameters, with a changeover time of ≤15 minutes.
