Detailed Embodiments

[0018] For the convenience of understanding by those skilled in the art, the following will further illustrate the present utility model in conjunction with embodiments and the appended Figures 1 - 3 drawings. The content mentioned in the implementation manners does not limit the present utility model.

[0019] See Figures 1 - 3 , an automatic heat shrinkage device for switch wires, comprising a workbench 1, a turntable 2 installed on the workbench 1, a rotating mechanism 21 for driving the turntable 2 to rotate, and heat shrinkage stations 3 and material receiving and feeding stations 4 located on both sides of the top of the turntable 2. Positioning jigs 6 for placing switch wires 5 are fixed on both sides of the top of the turntable 2. The two positioning jigs 6 are rotationally symmetric about the center of the turntable 2. The heat shrinkage station 3 includes at least one hot air gun 31 for heat shrinking a heat shrinkable tube 50 sleeved on the switch wire 5. A start button 11 for controlling the rotation of the rotating mechanism 21 is installed at the front end of the workbench 1.

[0020] In the automatic heat shrinkage device for switch wires of the present utility model, positioning jigs 6 for placing switch wires 5 are fixed on both sides of the top of the turntable 2. When the switch wire 5 on one side is undergoing heat shrinkage, the positioning jig 6 on the other side can receive or feed materials. The material receiving and feeding and heat shrinkage are carried out synchronously, greatly improving the work efficiency, saving space, having a simple structure, being convenient for operation and control, and enhancing the product quality stability. Specifically, an operator places the switch wire 5 sleeved with the heat shrinkable tube 50 into the positioning jig 6, presses the start button 11, and the rotating mechanism 21 drives the turntable 2 to rotate 180 degrees to the heat shrinkage station 3. The hot air gun 31 automatically starts to heat shrink the heat shrinkable tube 50 sleeved on the switch wire 5. When the heat shrinkage reaches the set time, it automatically stops. During the heat shrinkage time of the device, the switch wire 5 is taken and placed by the other positioning jig 6, which is completed by the same person.

[0021] In this embodiment, the switch wire 5 includes a switch assembly 51, a circuit board assembly 52, and a wire harness assembly 53 connected between the switch assembly 51 and the circuit board assembly 52. The positioning jig 6 includes a bottom plate 61, and a switch placement seat 62 for placing the switch assembly 51, a wire harness placement seat 63 for placing the wire harness assembly 53, and a circuit board placement seat 64 for placing the circuit board assembly 52, which are sequentially fixed on the outer side of the top of the bottom plate 61. Three placement seats are respectively adopted for the three parts of the switch wire, which is convenient for positioning the switch wire. Specifically, the circuit board placement seat 64 is provided with a movable buckle 641 for locking the circuit board assembly 52.

[0022] In this embodiment, the positioning jig 6 further includes two support arms 65 fixed on the inner side of the top of the bottom plate 61 and a flip plate 66 hinged between the tops of the two support arms 65. The flip plate 66 covers the top of the wire harness placement seat 63. By adopting the flip plate 66, it is possible to prevent the hot air from blowing to the position that does not need heat shrinkage. Optionally, the flip plate 66 can be made of a heat insulating plate.

[0023] In this embodiment, a first heat shrinkable tube 501 is sleeved on the wire harness assembly 53. A first through hole 661 is formed in the turnover plate 66 corresponding to the position of the first heat shrinkable tube 501. The heat shrinkage station 3 includes a first hot air gun 311 for heat shrinking the first heat shrinkable tube 501. The first heat shrinkable tube 501 can tighten multiple wires, and the first hot air gun 311 is used to perform heat shrinkage on it.

[0024] In this embodiment, the first hot air gun 311 is inclined. The heat shrinkage station 3 further includes a gantry 7 fixed to the rear end of the top of the workbench 1, a slide rail 71 horizontally fixed to the front end of the top of the gantry 7, and a first mounting bracket 72 slidably connected to the front end of the slide rail 71. The first hot air gun 311 is fixed to the first mounting bracket 72. Since the length of the first heat shrinkable tube 501 is relatively long, the inclined first hot air gun 311 moves left and right to perform heat shrinkage on the first heat shrinkable tube 501.

[0025] In this embodiment, a second heat shrinkable tube 502 is sleeved on the connection part between the switch assembly 51 and the wire harness assembly 53. A second through hole 662 is formed in the turnover plate 66 corresponding to the position of the second heat shrinkable tube 502. The heat shrinkage station 3 includes a second hot air gun 312 for heat shrinking the second heat shrinkable tube 502. The second heat shrinkable tube 502 can tighten the joint part between the switch and the wire, and the second hot air gun 312 is used to perform heat shrinkage on it.

[0026] In this embodiment, the second hot air gun 312 is vertically arranged. The heat shrinkage station 3 further includes a second mounting bracket 73 fixed to one side of the gantry 7. The second hot air gun 312 is fixed to the second mounting bracket 73. Since the length of the second heat shrinkable tube 502 is relatively short, it is only necessary to use the vertically arranged second hot air gun 312 fixed to perform heat shrinkage on the second heat shrinkable tube 502.

[0027] In this embodiment, an indicator light 12 for indicating the completion of heat shrinkage of the switch wire is installed at the front end of the workbench 1.

[0028] It should be noted that the automatic heat shrinkage device for the switch wire of the present invention further includes a control device (such as a PLC controller). The control device is electrically connected to the rotation mechanism 21, the hot air gun 31, the start button 11 and the indicator light 12 respectively to realize the automatic control of the device, such as setting the temperature of the hot air gun 31, the heat shrinkage time, etc. The above settings are prior art and will not be elaborated here.

[0029] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
