What is the JH-02A?
The JH-02A is a fully automatic double-end crimping and single-end tinning machine manufactured by Dongguan Juhai Machinery Co., Ltd. It processes AWG#32 to AWG#18 electronic wire. The machine completes five operations in one automated cycle: fixed-length cutting, stripping, twisting, terminal crimping on both ends, and tinning on a single end.
What problems does the JH-02A solve?
PCB connection wires and sensor cables require one end soldered to a board and the other end terminated with a crimped connector. Traditional production uses separate machines for crimping and manual tinning. The JH-02A eliminates manual tinning by integrating both operations. This reduces labor cost and ensures consistent solder quality across all production batches.
What wire types and sizes does the JH-02A support?
The JH-02A processes UL1007 and UL1571 electronic wires. The supported wire range is AWG#32 to AWG#18. Maximum outer diameter is 0.6mm for AWG#32. For AWG#18, the machine accommodates standard electronic wire insulation thickness.

How does the servo control system work?
The JH-02A uses Inovance servo motors for all critical motion axes. Servo control applies to stripping depth, crimping height, tinning depth positioning, and wire length accuracy. Unlike pneumatic-only systems, servo control maintains consistent positioning across high-speed production runs. The servo system pairs with Hiwin and TBI ball screws and linear guides. This combination provides positioning accuracy of ±0.02mm for stripping and crimping operations.
What are the tinning station capabilities?
The JH-02A tinning station includes digitally controlled parameters. Tinning depth is programmable in 0.1mm increments. Tinning speed offers 9 adjustment levels. Dwell time in molten solder ranges from 0.1 to 2.0 seconds. Cooling time after tinning is independently configurable.
The flux dipping system includes adjustable dipping angle and depth. Automatic solder scraping occurs at programmable intervals (default: every 10 tinning cycles). This scraping removes surface oxidation from the solder pot, maintaining wetting consistency.
In production testing, the JH-02A achieves tinning coverage of 95-100% on conductor circumference with no bridging between strands. Rejection rate for tinning defects is below 0.5% under stable operating conditions.
How does the twisting mechanism perform?
The twisting station operates on wires with partial stripping. Twisting speed has 9 adjustment levels. Twisting stroke is programmable from 3mm to 10mm. Twisting blade depth adjusts in 0.05mm increments.
After twisting, the machine executes a programmed retract distance. This retract prevents conductor damage from sustained blade contact. The retract delay is adjustable from 0 to 500 milliseconds.
The twisting system works with partial stripping settings. For AWG#24 wire with 5mm partial strip, the JH-02A achieves a consistent 4-5mm twisted length with no broken strands.
What crimping capabilities does the machine offer?
The JH-02A uses a silent terminal crimping machine with 2.0 tons of crimping force. The crimping station accepts OTP horizontal and vertical dies. Crimping depth is digitally controlled. Higher depth values produce tighter insulation crimp.
Key crimping parameters include:
-
Crimping speed: adjustable from 1 to 9 (1 = slowest, 9 = fastest)
-
Crimp position offset: programmable per wire position (range: -5.0mm to +5.0mm)
-
Scrap cutting interval: programmable (default: every 10 crimps)
-
Fiber optic terminal detection: on/off selectable
-
Pressure monitoring: optional (recommended for critical applications)
The machine supports independent crimp position settings for each wire position. For multi-wire production, different terminal types can be crimped in the same cycle.
What inspection systems are integrated?
The JH-02A includes six standard inspection functions:
| Inspection | Detection method | Action on failure |
|---|---|---|
| Wire presence | Infrared sensor | Machine stops |
| Knot detection | Mechanical sensor | Machine stops |
| Low air pressure | Pressure switch | Alarm + stop |
| Terminal presence | Fiber optic sensor | Reject piece |
| Crimping anomaly | Optional pressure monitor | Reject piece |
| Wire jam | Servo torque monitoring | Machine stops |
All inspection parameters are computer-monitored through the touchscreen interface. The machine can be configured to reject defective pieces or stop production when anomaly rates exceed user-defined thresholds.
What is the user interface and programmability?
The JH-02A features a 10-inch full-color touchscreen from Xiankong. The interface supports multiple languages including English and Chinese.
Operators can program the following parameters independently:
-
Wire length (1mm increments)
-
Front strip length (0.1mm increments)
-
Rear strip length (0.1mm increments)
-
Front partial strip length (0.1mm increments)
-
Rear partial strip length (0.1mm increments)
-
Stripper blade depth (1-100 scale)
-
Retract distance after stripping (prevents conductor damage)
-
Batch count (1-9999 pieces)
-
Total production target (1-999999 pieces)
-
Pause time between batches (0-60 seconds)
The machine saves up to 50 complete parameter sets under file numbers. Operators recall a file number for recurring jobs. Changeover time between different wire types is 5-15 minutes depending on configuration.
