Description

Lead tubing apparatus and method for producing in-line capacitors

Technical Field

The invention relates to the field of direct-insert capacitors, in particular to a lead wire tube installing device for producing a direct-insert capacitor, a lead wire tube installing method and production equipment.

Background

The direct-insertion capacitor consists of a capacitor shell, a lead and an insulating tube: two lead wires with different lengths are connected to the bottom end of the capacitor shell; two sections of insulating tubes with certain length are respectively sleeved on the two leads; the joint of the lead and the tail end of the insulating tube is a bending position. The method mainly comprises the following steps in the production of the direct-insertion capacitor: 1) loading the capacitor shell and the lead assembly which are not sleeved with the insulating tube to a jig conveying device; 2) the jig conveying device conveys the capacitor shell and the lead assembly to the position of the lead tube installing device, and the lead tube installing device respectively sleeves a plurality of insulating tubes on the lead; 3) the lead bending device supports the tail end of the insulating tube to prevent the tail end of the insulating tube from sliding downwards and bends a lead positioned at the tail end of the insulating tube; 4) and the jig conveying device is used for blanking the bent direct-insertion capacitor to complete the production process of the direct-insertion capacitor. With the development of the in-line capacitor industry, the in-line capacitor production equipment has an increasingly important position.

The prior art has the following defects: 1. when the direct-insert capacitor is conveyed, the direct-insert capacitor jig is driven to move forwards by the driving device, when the jig moves to the tail end, the jig moving device lifts the direct-insert capacitor jig upwards, and then the driving device drives the jig moving device to move to the initial position so as to complete the circulation of the direct-insert capacitor jig; and two steps of lifting the jig upwards and moving the jig to the initial position are required to complete the circulation of the jig, so that the circulation steps of the jig are increased, and the circulation speed of the direct-insertion capacitor jig is reduced. 2. When an insulating tube is sleeved on the direct-insert capacitor lead, the insulating tube clamping hand is in a fixed length, only one group of pushing cylinders of the insulating tube mounting mechanism can push the insulating tube clamping hand forwards for a fixed stroke, and only insulating tubes with one length can be clamped and sleeved; when the direct-insert capacitor lead needs to be sleeved with an insulating tube with a longer length, the insulating tube clamping hand with a fixed length can only clamp the rear end of the insulating tube, and the front end of the insulating tube is suspended outside the insulating tube clamping hand; because the insulating tube has certain flexibility, the suspended insulating tube outside the insulating tube clamping hand is drooped under the action of gravity and is not aligned with the direct-insert capacitor lead wire, so that the longer insulating tube cannot be accurately sleeved on the direct-insert capacitor lead wire; meanwhile, the sleeving stroke of the longer insulating tube is different from that of the short insulating tube, and the insulating tube sleeving mechanism cannot complete the sleeving of the insulating tubes with the lengths of the insulating tube and the short insulating tube because the insulating tube clamping hand can only move for fixing the stroke, so that the adaptability of the equipment is reduced. 3. The direct-insert capacitor lead is directly bent after being sleeved with the insulating tube, when the direct-insert capacitor lead is inclined downwards, the insulating tube sleeved on the direct-insert capacitor lead is easy to slide downwards due to the fact that no insulating tube falling stopping mechanism is arranged, and the insulating tube on the bent direct-insert capacitor lead is lost, so that the production quality of the direct-insert capacitor is affected.

When retrieving the jig, only need tool pusher jack 22 to drive tool draw runner mechanism 23 backward movement: the rear of the lower end of the jig pushing block 232 is acted by the forward acting force of the direct-insert capacitor, and the pushing block resilience assembly 233 which is in contact with the front end of the jig pushing block 232 is acted by the forward acting force of the jig pushing block 232; the push block rebound spring in the push block rebound assembly 233 is compressed after being subjected to a forward acting force, and the jig push block 232 also rotates forward to drive the lower end of the jig push block 232 to move upwards to be above the upper surface of the direct-insert capacitor; at this time, the lower surface of the direct-insertion capacitor is tightly attached to the lower surface of the jig guide block 24 by the upward jacking force of the jig rebound assembly 252 without moving backwards along with the jig push block 232; then the jig slide bar mechanism 23 continues to move backwards to drive the jig push block 232 to move backwards to the initial position along the upper surface of the in-line capacitor, so as to complete the cycle process of the jig; in the whole jig circulation process, the jig pushing mechanism 22 is only required to drive the jig sliding strip mechanism 23 forwards and the jig pushing mechanism 22 is only required to drive the jig sliding strip mechanism 23 backwards, and the jig does not need to be moved upwards, so that the steps of jig circulation are reduced.

The lead wire tubulating device 3 solves the problems that when an insulating tube is sleeved on a direct-insert capacitor lead wire, an insulating tube clamping hand is in a fixed length, and an insulating tube mounting mechanism only has one group of pushing cylinders and can only push the insulating tube clamping hand forwards for a fixed stroke, so that only insulating tubes in one length can be clamped and sleeved; when the direct-insert capacitor lead needs to be sleeved with an insulating tube with a longer length, the insulating tube clamping hand with a fixed length can only clamp the rear end of the insulating tube, and the front end of the insulating tube is suspended outside the insulating tube clamping hand; because the insulating tube has certain flexibility, the suspended insulating tube outside the insulating tube clamping hand is drooped under the action of gravity and is not aligned with the direct-insert capacitor lead wire, so that the longer insulating tube cannot be accurately sleeved on the direct-insert capacitor lead wire; meanwhile, the sleeving stroke of the longer insulating tube is different from that of the short insulating tube, and the insulating tube sleeving mechanism cannot complete the sleeving of the insulating tubes with the lengths of the insulating tube and the short insulating tube because the insulating tube clamping hand can only move for fixing the stroke, so that the problem of adaptability of equipment is solved.
