Description

Technical Field

[0001] The utility model relates to the technical field of heat shrinkage of heat shrinkable tubes, in particular to a heat shrinkage device for heat shrinkable tubes. Background Art

[0002] Heat shrink tubing is required at the connection point between the wiring harness and the connector. By heating the heat shrink tubing, it shrinks and tightly wraps around the connection point, achieving insulation, sealing, and waterproofing. Currently, the heat shrink tubing is generally heated by using a hot air gun to blow hot air in one or more directions. This heating method has the following drawbacks: the hot air does not evenly cover the surrounding area of the heat shrink tubing, which may cause uneven shrinkage. In addition, the temperature of the hot air does not rise quickly enough during heating, resulting in a long shrinkage time, which affects production efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a heat shrinking device for a heat shrinkable tube, which can heat the heat shrinkable tube evenly, shrink the heat shrinkable tube quickly, and shorten the heating time.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A heat shrink device for heat shrink tubing includes a frame, and also includes a first translation mechanism, a second translation mechanism, a copper sleeve heater, and a digital temperature controller arranged on the frame; the first translation mechanism is arranged in the middle of the frame, and the first translation mechanism is provided with an air claw, which is used to clamp and fix the wire; the second translation mechanism is arranged on the upper part of the frame; the copper sleeve heater is installed on the second translation mechanism; the digital temperature controller is installed on one side of the frame, and the digital temperature controller is electrically connected to the copper sleeve heater.

[0006] As a further elaboration of the above technical solution:

[0007] The first translation mechanism includes a first linear guide rail, a first mounting plate, a motor and a synchronous belt transmission assembly. The first linear guide rail is installed in the middle of the frame along the length direction of the frame. The first mounting plate is fixed on the slider of the first linear guide rail. The air claw is installed on the first mounting plate. The motor is used to drive the synchronous belt transmission assembly to work, and the synchronous belt transmission assembly is connected to the first mounting plate.

[0008] The second translation mechanism includes a second linear guide rail, a second mounting plate and a cylinder. The second linear guide rail is installed on the upper part of the frame along the length direction of the frame. The second mounting plate is fixed on the slider of the second linear guide rail. The copper sleeve heater is installed on the second mounting plate. The piston rod output end of the cylinder is connected to the second mounting plate.

[0009] The second mounting plate is provided with a mounting base for mounting the copper sleeve heater. The mounting base includes a base plate, a shell and a C-shaped fixing piece. The shell and the C-shaped fixing piece are fixedly connected to the base plate. The shell is sleeved on the copper sleeve heater, and the C-shaped fixing piece is connected to the tail of the copper sleeve heater.

[0010] The frame is also provided with a limit plate, which is vertically fixed to the upper part of the frame and located between the cylinder and the second mounting plate. The limit plate is provided with a through hole for the piston rod of the cylinder and the wires of the copper sleeve heater to pass through. The limit plate is used to limit the second mounting plate.

[0011] Compared with the prior art, the present invention achieves at least the following beneficial effects:

[0012] The wires with the heat shrink tubing positioned are transported to the heat shrink tubing device through the conveying mechanism of the production line. The first translation mechanism can drive the air gripper to move to the specified position of the wire. The air gripper clamps and fixes the wire to prevent the heat shrink tubing from moving due to the movement of the wire. The second translation mechanism drives the copper sleeve heater to move toward the wire. When the copper sleeve heater moves to the heat shrink tubing of the wire, the copper sleeve heater starts to heat. Since the copper sleeve heater is cylindrical, it can evenly heat the heat shrink tubing on all sides, achieve rapid heat shrinkage, shorten the heating time, and improve production efficiency.

[0023] The second translation mechanism 3 is arranged on the upper part of the frame 1; the copper sleeve heater 4 is installed on the second translation mechanism 3; the second translation mechanism 3 is used to drive the copper sleeve heater 4 to move along the length direction of the frame 1, thereby moving the copper sleeve heater 4 to the heat shrink tube of the wire. The copper sleeve heater 4 is sleeved on the heat shrink tube, which can evenly heat the four sides of the heat shrink tube, causing the heat shrink tube to shrink rapidly, thereby improving production efficiency.

[0024] The digital temperature controller 5 is installed on one side of the rack 1 and is electrically connected to the copper sleeve heater 4. In order to accurately control the temperature, a temperature sensor, such as a K-type thermocouple, can be set near the copper sleeve heater 4 to measure the temperature more accurately. The digital temperature controller 5 samples and monitors the heating temperature of the copper sleeve heater 4 in real time through the temperature sensor, and intelligently controls the operation of the copper sleeve heater 4 to ensure stable heating temperature.

The air gripper 6 is mounted on the first mounting plate 22. The motor drives the synchronous belt drive assembly, and the synchronous belt of the synchronous belt drive assembly is connected to the first mounting plate 22. The synchronous belt drive assembly transmits power to the first mounting plate 22, thereby driving the first mounting plate 22 and the air gripper 6 to move along the first linear guide 21. Preferably, the air gripper 6 is a parallel opening and closing type air gripper.

[0026] refer to Figure 4 Optionally, the second translation mechanism 3 includes a second linear guide 31, a second mounting plate 32, and a cylinder 33. The second linear guide 31 is mounted on the upper portion of the frame 1 along its length. The second mounting plate 32 is fixed to the slider of the second linear guide 31. The copper-sheathed heater 4 is mounted on the second mounting plate 32. The cylinder 33 is mounted on the upper portion of the frame 1, and the output end of the piston rod of the cylinder 33 is connected to the second mounting plate 32. The piston rod of the cylinder 33 retracts and retracts, thereby driving the second mounting plate 32 and the copper-sheathed heater 4 to move along the second linear guide 31. Preferably, the cylinder 33 is a freely mountable cylinder.

[0027] Specifically, a mounting base 7 for mounting the copper sleeve heater 4 is provided on the second mounting plate 32. The mounting base 7 includes a substrate 71, a shell 72 and a C-shaped fixing member 73. The shell 72 and the C-shaped fixing member 73 are fixedly connected to the substrate 71, and the shell 72 is mounted on the copper sleeve heater 4.

The limit plate 8 is used to limit the second mounting plate 32, and the limit plate 8 is provided with a through hole 81 for the piston rod of the cylinder 33 and the wires of the copper sleeve heater 4 to pass through.

[0029] The working principle of this utility model is:

[0030] The wires with the heat shrink tube positioned are transported to the heat shrink device of the heat shrink tube through the conveying mechanism of the production line. The first translation mechanism 2 can drive the air claw 6 to move to the specified position of the wire. The air claw 6 clamps and fixes the wire to prevent the movement of the wire from causing the heat shrink tube to move. The second translation mechanism 3 drives the copper sleeve heater 4 to move toward the wire. When the copper sleeve heater 4 moves to the heat shrink tube of the wire, the copper sleeve heater 4 starts to heat. Since the copper sleeve heater 4 is cylindrical, the heat shrink tube can be evenly heated on all sides, achieving rapid heat shrinkage and shortening the heating time. After the heat shrink tube is heated, the second translation mechanism 3 drives the copper sleeve heater 4 to move back for reset, and the air claw 6 is released to take out the wire that has completed the heat shrink tube processing.
