Description

Fast needle wire winding and side pressing process and special equipment

Technical Field

The invention relates to a winding wire of a connecting pile of a driving power supply of an LED filament lamp. The filament lamp is a light-emitting diode lamp.

Background

Chinese patent application No. 2020102822487 discloses an automatic filament winding device for a quick-acting needle bulb. Since the diameter of the thinnest part of the end of the fast needle is also equal to half of the width of a circuit board of the driving power supply, a distance needs to be kept between the connecting pile and other parts of the driving power supply to leave a space for the fast needle to enter for winding, and the driving power supply is not compact enough. The design of deflecting the connecting pile by an angle for wire winding allows the connecting pile to be close to other parts of the driving power supply, so that the driving power supply with compact volume can be manufactured.

Detailed Description

Examples 1 to 8 show example 1.

Example 1, a fast needle winding side pressure special device is manufactured, and the fast needle winding side pressure process is performed, wherein the special device comprises a main rotating platform, a clamping mechanism 1, a fast needle assembly, a hook piece 13, scissors 9 and a push rod 10. A plurality of workpiece stations are uniformly distributed on the main rotating platform in a circumferential manner, and each workpiece station is connected with a workpiece bulb shell. The fast needle assembly comprises a pair of two groups of fast needle mechanisms 2 which are symmetrically arranged at two sides of the driving power supply; the fast needle mechanism comprises a fast needle 3; the quick needle comprises a V-shaped groove 4 and a bend 5 which is connected with the V-shaped groove or is integrally manufactured with the V-shaped groove. The bend 5 receives exactly one connection stub 8 of a filament lamp drive power supply 7 wound with a lead wire 6. The fast needle is driven by a stepping motor, and the state of the fast needle can be precisely controlled.

The process of the fast needle wire winding side pressure process implemented by the special fast needle wire winding side pressure equipment comprises the following steps:

preparing: the clamping mechanism 1 clamps the driving power supply 7 to enable the driving power supply to be sleeved right above the workpiece bulb shell which rotates in place, and sinks to a process station; two connecting piles 8 of the driving power supply are vertically and upwards separated at two sides. When the driving power supply sinks, two vertically upward leading wires 6 of the workpiece bulb shell are extruded to two sides as shown in figure 1; in the next procedure, two connecting piles 8 of the power supply are driven obliquely or plate-obliquely to be parallel to and close to the lead wires.

Step 1: the two connecting piles 8 are pulled outwards obliquely by the hook pieces 13, so that the quick needles can be conveniently inserted; as shown in fig. 3.

Because the connecting pile 8 is inclined, the quick pins 3 do not interfere with the driving power supply 7 when winding wires on the connecting pile 8 which is close to other electric components 12 of the driving power supply. The proximity of the connection stub 8 to the other electrical components 12 of the drive power supply 7 means that the overall drive power supply 7 is more compact.

And a step 2: the quick-action sleeve is attached to the stub and rotated to wind the wire 6 around the stub 8, as shown in figure 4.

Step 3: the quick needle 3 is withdrawn. The state of the fast needle at this time is the same as that in fig. 3.

And step 4: the connecting piles 8 are trimmed by scissors; as shown in fig. 5.

Step 5: pressing the trimmed connecting pile 8 together by using a push rod 10; two connecting piles 8 are parallel and form an inclination angle of 30-45 degrees with the circuit board 11. As shown in FIGS. 6 to 8.

The push rod 10 includes a shaped surface 14 which defines the final configuration and spatial position of the connector when pushed against the connector to achieve the desired press-together effect. The shaped surface may be tested multiple times to determine specific parameters.

In one possible design, the closest distance between the connection stub 8 and the other components 12 of the drive power supply is less than or equal to 4 mm.
