Description

Technical Field

[0001] The present application relates to the field of automobile product production, and in particular to a heat shrinkable connection device for a sleeve at the end of a wire of an automobile heating pad. Background Art

[0002] A car heating pad is a seat cushion that heats the car seat so that people do not feel cold when driving.

[0003] The car heating pad uses electricity for heating, so the heating pad includes a flexible heating body and a wire. There are two wires, and the ends of the two wires are close to each other and arranged in parallel. The end of each wire is provided with a terminal, which will be welded and fixed to the end of the wire; after fixing, an insulating protective cover is put on the end of the wire, and the protective cover is tightly wrapped around the end of the wire through heat shrinkage treatment.

[0004] To improve the production efficiency of heating pads, an automatic heat shrink tubing attachment device is currently used. This device primarily consists of a centrifugal disc and a moving mechanism. The disc conveys the heat shrink tubing one by one, while the moving mechanism controls the movement of the wires toward the discharge end of the disc, ultimately inserting the wire ends into the tubing. Because the wires are arranged side by side, the positioning accuracy and stability of the heat shrink tubing at the end of the disc are low, resulting in frequent unsuccessful attachments and impacting production efficiency.

[0015] By adopting the above technical solution, the transfer component places the heat shrink tubing on the propulsion seat, and then the propulsion seat moves close to the targeting fixture, thereby installing the heat shrink tubing on the wire.

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The embodiment of the present application discloses a heat shrinkable connection device for the end sleeve of a car heating pad wire, such as Figure 1As shown, it includes a frame 1, on which a feeding mechanism 3, a targeting fixture 2 and a docking mechanism 4 are provided. The targeting fixture 2 is used to fix two parallel wires 5; the feeding mechanism 3 is used to make a hot-melt sleeve of a determined size and transport the heat-capable sleeve to the docking mechanism 4, and the docking mechanism 4 is used to sleeve the heat-capable sleeve on the end of the wire 5.

[0028] like Figure 1 As shown, the targeting fixture 2 includes a fixed threshold 21 and a lifting plate 22. The fixed threshold 21 is fixedly connected to the frame 1. The lifting plate 22 is located above the fixed threshold 21 and is slidably connected to the frame 1 in the vertical direction. A plurality of iron sheets are fixedly connected to the lifting plate 22 on the side facing the fixed threshold 21. Correction grooves 221 are formed between adjacent iron sheets. The number of correction grooves 221 is consistent with the number of wires 5, and the two correspond one-to-one. When two wires 5 are placed on the fixed threshold 21 and the lifting plate 22 is lowered, the wires 5 simultaneously abut against the groove walls of the correction grooves 221, the lower edge of the lifting plate 22, and the upper edge of the fixed threshold 21, thereby "fixing" the wires 5 to the frame 1.

[0029] like Figure 1 As shown, the feeding mechanism 3 includes a feed roller 31, a cutting blade 32, and a transfer assembly 33. Two material reels 11 are rotatably mounted on the frame 1. Heat shrink tubing material 12 is wound around the material reels 11, and the material reels 11 rotate to unwind the heat shrink tubing material 12. The feed rollers 31 are rotatably connected to the frame 1. A motor (not shown) is provided on the frame 1 to drive the feed rollers 31. The feed rollers 31 roll against the heat shrink tubing material 12, which, through friction, drives the heat shrink tubing material 12 to move and off the material reels 11. The cutting blade 32 is located on the side of the feed roller 31 facing away from the material reels 11 and is slidably connected to the frame 1. The sliding direction of the cutting blade 32 is perpendicular to the length of the heat shrink tubing material 12. In this embodiment, the length of the heat shrink tubing material 12 discharged by the cutting blade 32 is consistent with the direction of movement, both being horizontal. The cutting blade 32 moves in the vertical direction. The transfer assembly 33 is located on the side of the cutting knife 32 away from the feeding roller 31. The cutting knife 32 can cut off two heat shrink tubes in a single movement. The transfer assembly 33 is used to receive the two heat shrink tubes 13 and transport them to the docking mechanism 4.

[0030] like Figure 1As shown, the transfer component 33 includes a transfer cylinder 331, which is slidably connected to the frame 1. A driving source for controlling the sliding of the transfer cylinder 331 is provided on the frame 1. The sliding direction of the transfer cylinder 331 is horizontal and perpendicular to the length direction of the heat shrinkable sleeve 13; the transfer cylinder 331 is a clamping cylinder, and the clamping jaws of the clamping cylinder move vertically toward or away from each other. Two transfer grooves 332 are provided on the two clamping jaws. When the two clamping jaws abut against each other, the groove wall of the transfer groove 332 abuts against the heat shrinkable sleeve 13 to be cut off, thereby achieving the clamping of the heat shrinkable sleeve 13. Then the transfer cylinder 331 can carry the two heat shrinkable sleeves 13 to move toward the docking mechanism 4.

[0031] like Figure 1 and 2 As shown, the docking mechanism 4 includes a propeller seat 41 and a pusher body 43. The propeller seat 41 is slidably connected to the frame 1. The sliding direction of the propeller seat 41, the length direction of the heat shrink tubing 13 on the clamping cylinder, and the length direction of the wire 5 on the targeting fixture 2 are all parallel. The frame 1 is provided with an electric screw for driving the propeller seat 41 to move. Two temporary pins 42 are fixedly connected to the propeller seat 41. The length direction of the temporary pins 42 is consistent with the sliding direction of the propeller seat 41. A single temporary pin 42 is coaxially aligned with a wire 5 on the targeting fixture 2. The pusher body 43 is slidably arranged on the propeller seat 41. The sliding direction of the pusher body 43 is consistent with the sliding direction of the propeller seat 41. The propeller seat 41 is provided with an electric screw for driving the pusher body 43 to slide. When the transfer cylinder 331 carries the heat shrink tubing 13 to the docking mechanism 4, the heat shrink tubing 13 on it is located between the targeting fixture 2 and the propeller seat 41, and the single heat shrink tubing 13 and the temporary pin 42 are coaxially aligned. At this time, the pushing seat 41 moves, so that each heat shrink sleeve 13 is passed through by the corresponding temporary pin 42 respectively, the clamping claw of the clamping cylinder opens, and the two heat shrink sleeves 13 remain on the temporary pin 42, and the pushing body 43 and the heat shrink sleeve 13 abut against one end of the targeting fixture 2; then the pushing seat 41 continues to move closer to the targeting fixture 2. When the heat shrink sleeve 13 contacts the end of the wire 5, the pushing seat 41 stops, and at the same time, the pushing body 43 moves closer to the targeting fixture 2, and the heat capacity sleeve moves due to the force thrust, and is removed from the temporary pin 42 and is sleeved on the end of the wire 5, thereby realizing the docking installation of the heat shrink sleeve 13 and the end of the wire 5.

[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
