Description

Eccentric fast needle assembly

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 6 show example 1.

Embodiment 1, a special device for one-step wire winding of a driving power supply is manufactured, and a one-step wire winding process of the driving power supply is executed, wherein the special device comprises a main rotating platform, a clamping mechanism 1 and an eccentric fast needle assembly. 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 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 a filament lamp driving power supply 7 wound with a lead wire 6. 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 a prior art bulb lead wire automatic winding device, the eccentric quick needle 3 has much reduced volume at the position except for the offset wings 4, so that the eccentric quick needle can move downwards to sleeve the connecting pile 8 close to the part of the driving power supply 7, bend the connecting pile plate by means of the offset wings, wind the lead wire on the connecting pile and bend the connecting pile plate by means of the offset wings.

The eccentric fast needle assembly is connected with the foundation through an arc-shaped moving pair mechanism 9 and is in transmission connection with a rotation driving mechanism. The eccentric quick-action needle assembly is pushed to rotate clockwise along the arc-shaped moving pair mechanism 9 and to pull the connecting pile 8 to rotate by a deflection angle 10 to the two-dot chain oblique line position shown in fig. 1 and also shown in fig. 4. And after the wire winding is finished, the wire is pushed to rotate along the arc-shaped moving pair mechanism 9 anticlockwise, and the connecting pile 8 is pulled to rotate by a deflection angle 10 to be in a vertical state, as shown in figures 1 and 5.

The process of implementing the one-step wire winding process of the driving power supply by the one-step wire winding special equipment of the driving power supply comprises the following preparation and working procedures 1-5:

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 fast needles 3 move downwards to the right position under the condition of keeping the eccentric wings 4 away from the driving power supply, and are respectively sleeved on two connecting piles 8, as shown in figure 1;

and a step 2: the eccentric quick pin 3 turns clockwise by an angle of deflection 10 with the root of the connecting pile 8 as a center to bend the connecting pile 8, as shown in fig. 4.

Because the connecting pile 8 is bent by the plate, 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.

Step 3: 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 part surrounded by the two-dot chain line circle in figure 2, and pushes the lead wire 6 to wind on the connecting pile 8, as shown in figure 4;

and step 4: the eccentric fast needle 3 keeps the offset wing 4 far away from the driving power supply 7, and turns anticlockwise by an offset angle 10, namely a plate-straight connecting pile 8, by taking the root of the connecting pile 8 as a circle center, as shown in fig. 5;

step 5: the eccentric fast needle 3 moves upwards; the process comprises the following steps: the connecting piles are trimmed with scissors as shown in fig. 6.

The direction of the force and the point of action of the plate bending and plate straightening wings 4 are indicated by the thick arrows in fig. 2.

The deflection angle range comprises 5-45 degrees.

In one possible design, instead of using the arc-shaped moving pair mechanism 9, other ways include using a steering engine or a pneumatic element to drive the eccentric fast needle assembly to rotate — as described in the related art.

In one possible design, the eccentric fast needle uses a motor with revolution counting or a motor system with final state control to determine the state of its eccentric wing and replace the stepping motor with it.
