Description

Eccentric fast needle wire winding flat-pressing driving power supply and wire winding flat-pressing filament lamp

Technical Field

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 9 show example 1.

Example 1, a filament-wound flat-pressure filament lamp 10 was manufactured, including a bulb 11, a driving power supply 7, and a base 12; the bulb comprises a closed glass envelope 13 and a filament lamp body 14 enclosed in the glass envelope. The filament lamp main body is connected with the outside by two leading wires 6; the driving power supply comprises a circuit board 15, an electrical component 16 welded on the circuit board and two connecting piles 8 welded on the circuit board, and two leading wires 6 are wound on the two connecting piles 8 to realize the electrical connection of the two connecting piles; the connecting piles 8 are flattened on both sides of the driving power supply circuit board.

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

The wire winding process of the driving power supply comprises the following steps: manufacturing a connecting pile wire winding special device, and executing the eccentric fast needle wire winding flat pressing driving power supply connecting pile wire winding process, wherein the special device comprises a main rotating platform, a clamping mechanism 1 and an eccentric fast needle assembly. The eccentric fast needle assembly comprises a pair of two groups of eccentric fast needle mechanisms 2 which are symmetrically arranged at two sides of a driving power supply; the eccentric fast needle mechanism comprises an eccentric fast needle 3; the eccentric fast needle comprises a wing 4 and a straight groove 5 which is connected with the wing or is made integrally with the wing and has a semicircular cross section. The shape of the deflector comprises a regular trapezoid. The straight groove 5 accommodates exactly one connection stub 8 of the drive power supply of the filament lamp around which the lead wire 6 is wound. The eccentric fast needle is driven by a stepping motor, and the state of the eccentric fast needle can be precisely controlled.

Compared with the eccentric quick needle of the prior art bulb lead wire automatic winding device, the eccentric quick needle 3 has much reduced volume at the position except the offset wing 4, so that the eccentric quick needle can move downwards to directly press and sleeve the connecting pile 8 which is close to the part of the driving power supply 7, and is ready for the next process.

The eccentric fast needle wire winding flat pressing drive power supply connection pile wire winding special equipment implements the eccentric fast needle wire winding flat pressing drive power supply connection pile wire winding process:

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 eccentric quick needles 3 are pressed downwards to respectively press the two connecting piles 8 outwards to be deviated in place and are sleeved on the connecting piles, and the state of the connecting piles is changed from that shown in figure 1 to that shown in figure 4.

Because the connecting pile 8 is biased, the eccentric quick pin 3 does not interfere with the driving power supply 7 when the wire is wound on the connecting pile 8 which is close to the other part of the driving power supply. The proximity of the connection stub 8 to the other components of the drive power supply 7 means that the overall drive power supply 7 is more compact.

And a step 2: the eccentric fast needle 3 rotates to wind the lead wire 6 on the connecting pile 8. when the eccentric fast needle 3 rotates, the offset wing 4 sweeps the space where the lead wire is located, as shown by the circle of the two-dot chain line in figure 2, and pushes the lead wire 6 to wind on the connecting pile 8, as shown in figure 4.

Step 3: the eccentric quick pin 3 is positioned above the connecting pile 8 and moves upwards to be withdrawn. Returning to the state shown in figure 1.

And step 4: the connecting piles 8 are trimmed by scissors 9; as shown in fig. 5.

Step 5: flattening the connecting pile by using a push rod; as shown in fig. 6.

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 subjected to multiple tests to determine the parameters.

The finished eccentric fast needle wire winding flat pressing driving power supply is shown in fig. 7 and 8.

A filament wound flat pressed filament lamp is shown in fig. 9.

Embodiment 1 also includes the content of the embodiment of realizing the eccentric fast needle wire winding flat pressing driving power supply.
