H4 Halogen Lamp Assembly Line

* Function Description:
1.The Fixring is fed through the vibrating disc
2.Our visual system determines the direction of the fixring and sends adjustment instructions to the servo motor
3.Calibrate the orientation of the fixring standardize the direction of the large and small sides
4.Cylinder presses the capsule into the fixring

The H4 Capping Machine is a multi-process integrated equipment.

* Function Description:
1. The base is fed through the vibrating disc.
2. Capping Machine fist will bend the three bulb pins into three-pronged pins.
3. Alloy cutting blade cut off the excessively long portions of the pins to ensure the solder joints are smooth and visually appealing. Then press       base into the fixring.
4. Fiber optic sensors detect whether each of the three bulb pins has successfully passed through the base.Unqualified products will be                    automatically rejected.

* Function Description:
Argon arc Leadwire Welding Machines generate electric arcs to melt the metal points of pins and base for welding purposes. Meanwhile, based on product characteristics and customer requirements, we additionally integrate leakage testing and cold-state resistance inspection functions into the basic capabilities of this Leadwire Welding Machine.

Noted:
1. Leakage testing：Bulbs with missing solder joints or burned-through Base will have unqualified products automatically rejected after leakage testing.
2. Cold-state resistance inspection：If the filament has a cold solder joint, its resistance value will be relatively high, and unqualified products will be automatically rejected after the resistance test.

We adopt the clamping Fixring method for focusing, which will not damage the capsule.

* Function Description:
The assembly parts fixed to the jig are controlled by the vision system information entered to control the movement of the servo motor X,Y,Z and R axis unit, and the Dipped Beam Filament （e,B1/29.5，B2/29.5，B1/33,B2/33,H/29.5,H/33） of the bulb accurately matches the set value before completing with resistane welding. The assembled product is moved to the next process by the conveyor system.

The top-coating process is a process in which a coating is made on the surface of the glass tube end of the bulb to inhibit the light of the bulb illuminated from the vehicle’s headlamps directly forward.
⁠The process sequence automatically injects the assembled product to form a film with coated paint at the end of the glass tube surface and dries the paint at high temperatures baking.

For different glass materials, we offer two types of Top-coating machines and corresponding baking solutions：

1. Electric Heating Plate Top-Coating Machine
Applicable Object: Hard glass bulbs.
Core Baking Method: Uses an electric heating plate for heating.
Core Advantage: Uniform heating, which is less likely to cause stress on the bulbs.

2. Combined Electric + Flame Baking Coating Machine
Applicable Object: Quartz glass bulbs.
Segmented Baking Process:
Preheating Stage: Preheats the bulb via electric baking;
Preliminary Baking Stage: After the coating operation, continues with preliminary baking using electric heating;
Curing Stage: Finally, uses flame baking to cure the light-shielding coating.

Common Features:
Both Top-coating machines adopt a 700°C high-temperature baking process. Under this high-temperature condition, the silicon powder and iron powder in the light-shielding liquid can penetrate into the interior of the glass, ultimately ensuring that the light-shielding coating of the lamp has a firm adhesion effect.

* Function Description:
The H4 Final Inspection Machine performs final dimensional inspection on finished assembled H4 lamps, covering more than 20 inspection parameters. The program can be set to: the dimensional range specified in ECE standards, or the tolerance range of each parameter can be modified according to customer requirements.Unqualified products will be automatically rejected.

* Here are three options for you:
Laser marking/Inject printing/Pad printing

( This is Laser marking type)

* Function Description:
The finished product during the vision inspection is completed by marking [brand name, part number, specification, date of manufacture, origin, and other customer requirements] on the surface of the BASE according to the input value.

Finished products are automatically discharged onto trays, available in unloading modes such as Belt conveyor and Tray unloading.
