Description

Technical Field

[0001] This utility model relates to the field of plug manufacturing equipment technology, specifically to a three-plug crimping mechanism. Background Technology

[0002] The three-prong plug contains a three-prong plug frame. During manufacturing, the three thin wires of the wire to be soldered are soldered to the three terminals provided on the three-prong plug frame. After the three-prong plug frame is soldered, it is injected with glue in the subsequent injection molding process to form the finished three-prong plug.

[0003] The electrical performance of a three-prong plug depends on the welding quality between the thin wire of the wire to be soldered and the terminals provided on the three-prong plug frame. If there is any missing solder or poor soldering during the soldering process, it will affect the wire performance of the three-prong plug.

[0004] In the existing technology, the welding of the wire to be welded to the three-prong plug frame is carried out manually. The quality of the welding depends on the worker's skill level, and incomplete welding is inevitable, resulting in a high defect rate and low welding efficiency. Utility Model Content

A longitudinal slider 42 is slidably connected to the longitudinal guide rail, and an air extraction cylinder 43 is fixedly connected to the longitudinal slider 42 (see Figure 4The front end of the vacuum pump 43 is fixedly connected to an adsorption pusher 44, which is used to adsorb the three-prong plug frame 21.

[0036] See Figure 2 A mounting bracket is fixedly connected to the top wall of the base. A vertical slide block 51 is slidably connected to the mounting bracket, and three vertical welding heads 52 are fixedly connected to the vertical slide block 51. A side mounting seat 6 is fixedly connected to the top wall of the slide table 41. A fixed cross arm 61 is fixedly connected to the side mounting seat 6, and a release cylinder 62 is fixedly connected to the rear side of the fixed cross arm 61.

A wire-taking cylinder 64 is fixedly connected to the sliding cross arm 63, and a wire-taking clamp 65 is fixedly connected to the piston rod of the wire-taking cylinder 64.

[0037] Specifically, the piston rod of the release cylinder 62 is located on the chain link 1 in front of the welding station. Figure 4 Above the movable clamping plate 11 corresponding to the fixed clamping plate 12 at point B, the piston rod of the release cylinder 62 is used to press down the movable clamping plate 11 of the chain link 1 to release the wire 2 to be welded clamped at point B.

[0038] Specifically, a longitudinal cylinder is fixedly connected to the top wall of the side mounting base 6, and the piston rod of the longitudinal cylinder is fixedly connected to the sliding cross arm 63.

[0039] Specifically, the piston cylinder of the wire-taking cylinder 64 is fixedly connected to the inner end top wall of the sliding cross arm 63.

[0040] Specifically, the cable clamp 65 has two clamping arms 651, and the inner side of the clamping arms 651 is provided with anti-slip silicone.

[0041] Specifically, the mounting frame consists of two upright plates 53 and one horizontal plate 54. The two upright plates 53 are symmetrically arranged laterally, and the horizontal plate 54 is fixed to the top side of the two upright plates 53. A vertical drive cylinder 55 is fixed to the top wall of the horizontal plate 54. Two vertical guide rods are fixed to the bottom wall of the horizontal plate 54, and the lower ends of the vertical guide rods are fixed to the feeding seat 3.

[0043] Specifically, the lower inner side of the silicone chuck 34 is provided with a contoured chamfer 341 (see...). Figure 6 ).

[0044] Specifically, see Figure 5 The adsorption pusher head 44 is provided with three forward-extending abutment posts 441. The front end of each abutment post 441 is offset from the three plugs of the three-plug frame 21 and abuts against the rear wall of the three-plug frame 21. Each abutment post 441 has an air intake hole (not shown in the figure) at its front end. The adsorption pusher head 44 is provided with an air chamber (not shown in the figure). The air intake hole is connected to the air extraction cylinder 43 through the air chamber.

[0045] The working principle of this utility model is as follows:

[0046] The sprocket (not shown in the figure) drives the clamp chain along... Figure 1 The central direction moves intermittently towards A, and the clamping chain consists of multiple links 1 connected end to end. See Figure 3 A movable clamping plate 11 is hinged to the head side of the top wall of link 1, and a fixed clamping plate 12 is fixed to the tail side of the top wall of link 1. A return torsion spring (not shown in the figure) is provided at the hinge of the movable clamping plate 11. The return torsion spring returns the movable clamping plate 11 to an upward tilt, so that the end of the movable clamping plate 11 and the fixed clamping plate 12 of the adjacent link 1 can jointly clamp the wire 2 to be welded (e.g., Figure 3 (As shown).

[0047] When the wire clamping chain transports the wire 2 to be welded to the front of the welding station ( Figure 4 At point B, the clamping chain stops. The feeding mechanism (not shown) places a three-prong plug frame 21 into the rear end of the feeding trough 31. Then, the longitudinal slider 42 drives the suction cylinder 43 forward, causing the three abutment posts 441 of the suction pusher 44 to abut against the rear wall of the three-prong plug frame 21. Subsequently, the gas in the suction cylinder 43 is extracted, thereby creating a negative pressure at the suction hole (not shown) at the front end of the abutment post 441, thus adsorbing the three-prong plug frame 21. The longitudinal slider 42 drives the suction cylinder 43 and the three-prong plug frame 21 forward, causing the three-prong plug frame 21 to move forward until it abuts against the positioning step 311, achieving positioning. Then, the two silicone clamps 34 move inward, jointly clamping the three-prong plug frame 21, achieving positioning of the three-prong plug frame 21.

[0048] Subsequently, the piston rod of the release cylinder 62 moves down to push the movable clamp 11 corresponding to the fixed clamp 12 at point B, causing the movable clamp 11 to swing downward, thereby preventing it from clamping the wire 2 to be welded at point B.

[0049] Then, the sliding cross arm 63 drives the wire-taking cylinder 64 forward, and then the wire-taking cylinder 64 drives the wire-taking clamp 65 downward, and then the two clamping arms 651 clamp the wire 2 to be soldered at point B. Then, the sliding cross arm 63 drives the wire-taking clamp 65 and the wire 2 to be soldered to move backward together, so that the three thin wires of the wire 2 to be soldered contact the three terminals provided on the three-prong plug frame 21 respectively. Then, the three vertical soldering heads 52 move downward with the vertical slide 51, thereby soldering the three thin wires of the wire 2 to be soldered to the three terminals, realizing the soldering of the wire 2 to be soldered to the three-prong plug frame 21.

[0050] Next, the wire-retrieving cylinder 64 slightly moves the wire-retrieving clamp 65 and the welded wire upwards, allowing the three-prong plug frame 21 to pass over the positioning step 311. Then, the sliding cross arm 63 moves the wire-retrieving clamp 65 and the welded wire forward. Subsequently, the piston rod of the release cylinder 62 retracts, and the movable clamp 11 corresponding to the fixed clamp 12 at point B resets, thereby re-clamping the welded wire, which continues to travel with the clamping chain. The welded three-prong plug frame 21 forms a three-prong plug in the subsequent injection molding process.

[0051] The three-prong crimping mechanism of this invention can automatically feed the wire 2 to be welded. The release cylinder 62 can conveniently open and close the movable clamp 11 to clamp or release the wire 2. The sliding cross arm 63, the wire-taking cylinder 64, and the wire-taking clamp 65 can work together to feed and take the wire 2, and the taking process is accurate and fast. The adsorption pusher 44 can quickly adsorb the three-prong frame 21 to achieve accurate feeding. The positioning step 311 and the two clamping cylinders 35 can jointly clamp the three-prong frame 21 to ensure accurate positioning of the three-prong frame 21. The three-prong crimping mechanism of this invention can efficiently and accurately weld the wire 2 to the three-prong frame 21, improve welding efficiency, and reduce the defect rate.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
