Description

Technical Field

[0001] The invention belongs to the field of mechanical technology, and in particular relates to an integrated shell inserting mechanism. Background Art

[0002] Wire inserters are generally used to process the ends of wires used in connectors. Connectors bridge the gap between two or more isolated electronic circuits, enabling current flow and fulfilling the functions of various electronic components. Widely used across various industries, these machines begin by cutting standard electronic wires to the desired length. The ends are then peeled, terminals are stamped into a die, and the wire ends with terminals are inserted into a housing to secure them. The housing is designed with multiple jacks for accommodating the terminals, requiring alignment and positioning of the wire ends before insertion to ensure accurate insertion of the terminals.

[0003] Currently, the shell insertion mechanisms of automatic shell inserters on the market are all powered by a power shaft located within the machine's chassis. This power is transmitted from the chassis below the work surface to the shell insertion mechanism above the work surface via a connecting rod mechanism. Because the shell insertion mechanism requires multiple components to work together, it typically requires multiple sets of connecting rods connected to the machine's power shaft. The operation of an automatic wire shell inserter involves numerous mechanisms, each of which requires power via a power shaft. This results in a complex structure and difficult assembly, requiring high technical skills from the installation technician. Furthermore, in the event of a power failure, the chassis must be disassembled and the corresponding connecting rod mechanism must be found among the numerous connecting rod mechanisms for repair, which is very inconvenient.

The cam driving device 5 drives the plastic shell pushing device 4 and the plastic shell inserting device 3 respectively through the cam. The cam driving device 5 is connected to the wire clamping and pressing device 6 for transmission through the first transmission assembly 8. When in use, the plastic shell is transported to the working end of the plastic shell pushing device 4 by the plastic shell horizontal feeding device 2. The plastic shell pushing device 4 pushes the plastic shell to the working end of the plastic shell inserting device 3. The plastic shell inserting device 3 clamps the plastic shell and pushes it to the front end to the working end of the wire clamping and pressing device 6 so that the plastic shell is sleeved on the outer end of the wire. At the same time, the wire clamping and pressing device 6 clamps the wire to adjust the wire spacing. Then the wire clamping and pressing device 6 further pushes the plastic shell to the outer end of the guide so that the wire is inserted into the plastic shell. After that, the wire clamping and pressing device 6 presses the plastic shell and the outer end of the wire to complete the shell insertion action.

[0031] Combine Figure 2 Specifically, the plastic shell horizontal feeding device 2 comprises a horizontal feeding connecting plate 201, a horizontal feeding base 202, a guide rail seat 203, and a feed rail 204. One end of the horizontal feeding connecting plate 201 is fixedly connected to the side of the plastic shell insertion device 3, and the other end is supported by a sub-frame 205, the bottom end surface of which is flush with the bottom end of the base 1. The horizontal feeding base 202 is mounted horizontally on one side of the connecting arm, the guide rail seat 203 is fixedly connected to the horizontal feeding base 202, and the feed rail 204 is mounted horizontally on the guide rail seat 203. As shown in the figure, the feeding direction of the feed rail 204 is perpendicular to the length of the base 1. Therefore, the discharge port of the feed rail 204 is in the feeding path of the plastic shell pushing device 4. When a plastic shell emerges from the discharge port, the plastic shell pushing device 4 can push it to the plastic shell clamping and insertion device for clamping and insertion.

[0032] like Figure 3As shown, the rubber shell plug-in device 3 includes a plug-in socket 301, a first slide rail 302, a first slider 303, a first connecting bar 304, a plug-in socket connecting rod 305, a second slider 306, a second slide rail 307 and a clamping shell assembly 308.

In this way, the two cams act on the rear end of the first connecting bar 304 respectively to realize the plug-in and push functions. The first elastic return member 309 adopts a tension spring, and the contraction force of the tension spring can make the bearings 9 abut against the corresponding cams respectively. The rear end of the socket connecting rod 305 is fixedly connected to the front end of the first slider 303. The front end of the socket connecting rod 305 is connected to the second slider connecting seat 310.

The second slide rail 307 is fixed to the side of the socket connecting seat 301 near the first slide rail 302. The clamping shell assembly 308 is fixed to the second slide connecting seat 310. The socket connecting seat 301 provides lateral support for the entire device. Combined with the guidance of the first slide rail 302 and the second slide rail 307, the forward and backward movement of the clamping shell assembly 308 is more stable, thus ensuring the stability of the clamping shell assembly 308 when clamping the plastic shell for insertion, thereby improving the success rate of shell insertion. The clamping shell assembly 308 includes a clamping cylinder 3081 and two cylinder clamping arms 3082.

[0033] In addition, a test pin 311 is provided on the socket connector 301, and a detection piece 312 is provided on one of the cylinder clamp arms 3082. The test pin 311 cooperates with the detection piece 312 and is located behind the detection piece 312. When the detection piece 312 moves to the test pin 311 and contacts the test pin 311, the test pin 311 triggers a detection signal, thereby determining that the cylinder clamp arm 3082 on the clamp housing assembly 308 is properly clamping the plastic shell; otherwise, it is determined that the cylinder clamp arm 3082 of the clamping cylinder 3081 has a fault. A light shielding piece 313 is provided on the side of the first slider 303, and an optical coupler detector 314 is mounted on the side wall of the socket connector 301. The light shielding piece 313 can pass through the detection area of ​​the optical coupler detector 314 as the first slider 303 moves.

[0041] like Figure 8As shown, the plastic shell material blocking device 7 includes a material blocking cylinder 701, a fixed frame 702, a material blocking seat 703, a material blocking piece 704, and a material blocking slide 705. The fixed frame 702 is fixed to the front end of the socket connecting seat 301 and is located above the clamping claw cylinder 3081. The material blocking seat 703 is installed at the top of the fixed frame 702, and the material blocking cylinder 701 is installed downward at the top of the material blocking seat 703. The material blocking piece 704 is connected to the cylinder rod of the material blocking cylinder 701, and the material blocking slide 705 is fixed to the bottom end of the material blocking seat 703 and is provided with a vertical slide groove that runs through the material blocking slide 705. The material blocking piece 704 is slidably connected in the vertical slide groove, and the bottom end of the material blocking piece 704 can block the forward movement path of the push rod 405 when it moves downward. A plastic shell guide seat 706 is mounted at the lower end of the fixed frame 702. Within the plastic shell guide seat 706 are a discharge chute connected to the discharge port of the feed guide rail 204 and a guide groove for the push rod 405 to push the plastic shell forward. The guide groove is perpendicular to and connected to the discharge chute. The plastic shell blocking device 7 operates after the plastic shell clamping device clamps the plastic shell and moves it forward, causing the blocking piece 704 to move downward to block the front end of the guide groove.

[0042] The principle of the present invention is as follows: the driving motor 502 of the cam driving device 5 provides power, and the second transmission component 508 is used to reduce the power proportionally and transmit it to the first camshaft 503. The feeding cam 507 on the first camshaft 503 first pushes the plastic shell pushing device 4 forward, and the push rod 405 on the plastic shell pushing device 4 pushes the plastic shell from the discharge port of the feeding guide rail 204 in the plastic shell horizontal feeding device 2 to the working end of the plastic shell clamping device. At this time, the clamping claw cylinder 3081 drives the cylinder clamping arm 3082 to close and clamp the plastic shell. Then the inserting cam 505 pushes the plastic shell clamping device forward, so that it moves a certain distance along the first slide rail 302. At the same time, the first transmission assembly 8 drives the second camshaft 601 of the wire clamping and pressing device 6 to move synchronously, and the wire clamping cam 606 pushes the wire clamping push rod 6074 to close the wire clamping arm 6076 and clamp the wire. Due to the presence of the wire clamping spacer 6078, the wire is kept at a fixed distance. Then the wire pressing cam 604 presses down the bearing 9 on the wire pressing connecting block 6053, drives the slide bar 6052 to move downward, and presses down the wire pressing piece 6055 to complete the shell insertion action. Afterwards, the top sleeve cam 506 pushes the plastic shell clamping and inserting device further forward, so that the wire and plastic shell after the shell is inserted are sent away from the station of this shell insertion mechanism and go to the next process. The integrated shell insertion mechanism of the present invention adopts an independent drive system and power transmission system, has a small and compact structure, high integration, and is very convenient to disassemble and assemble, which is conducive to the transformation and upgrading of wire harness processing equipment such as shell insertion machines and automatic welding machines. It has a wide applicability and little modification to the original machine, and is suitable for popularization and practicality.
