[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Since the feeding component of the utility model can accommodate at least two heat shrink tubes of different specifications, the heat shrink tubes are sleeved on the sleeve component through the conveying component under the action of the switching component. The sleeve component is sleeved with different heat shrink tubes according to wire harnesses of different specifications, so that one device can realize the sleeve connection of different heat shrink tubes for wire harnesses of different specifications without adding equipment.

[0035] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Figures 1 to 8 A heat shrink tube sleeve device capable of switching heat shrink tubes of different diameters according to an embodiment of the utility model comprises:

[0038] The feeding component 1 includes a material storage tray 11 and a guide roller 12. The heat shrink tubes are stored in the material storage tray 11 and enter the conveying component 2 after being guided by the guide roller 12. The material storage tray 11 has multiple groups of heat shrink tubes wound therein. The material storage tray 11 may be a general specification for storing heat shrink tubes on the market. The entire material storage tray 11 can be directly replaced after use. The guide roller 12 is used to tension the heat shrink tubes so that the heat shrink tubes will not become loose due to stopping of movement during the entire process and will not be rolled into other components, causing failure of the entire equipment.

[0039] Conveying component 2: drives the heat shrink tube to leave the feeding component 1, and arrives at the sleeve component 5 after passing through the switching component 3 and the marking component 4; the conveying component 2 is the basis for driving the heat shrink tube movement of the entire device. Since the heat shrink tube is in a sheet shape when it is not opened, the conveying component 2 is also driven by the structure of the power roller to move the heat shrink tube in contact with it.

[0040] The switching component 3 includes a guide element, an on-off control element 32, an opening element 33, a switching drive 34 and a cut-off element 35; the switching drive 34 drives the guide element to translate, so that the heat shrink tubes of different specifications in the guide element move, and after being squeezed and opened by the opening element 33, they are sleeved on the sleeve component 5; the on-off control element 32 moves or stops the heat shrink tube, and the cut-off element 35 cuts off the heat shrink tube after the heat shrink tube is sleeved on the sleeve component 5 to a preset length; wherein the cut-off element 35 can be a cutting knife, and the blade is extended or retracted by a cylinder to cut off the heat shrink tube.

[0041] Specifically, the conveying assembly 2 includes a first conveying element 21, a second conveying element 22, a third conveying element 23 and a conveying drive element 24; the first conveying element 21, the second conveying element 22 and the driving end of the conveying drive element 24 are synchronously driven, and the third conveying element 23 can approach or move away from the first conveying element 21. When the third conveying element 23 approaches the first conveying element 21, the first conveying element 21 drives the heat shrink tube between the two to move. In this technical solution, after the heat shrink tube passes through the guide roller 12, it first contacts the first conveying element 21 and then contacts the second conveying element 22. The two The conveying elements rotate synchronously under the drive of a synchronous belt, and when the third conveying element 23 moves close to the first conveying element 21, the gap between the two will eventually be smaller than the thickness of the heat shrink tube. At this time, the heat shrink tube moves under the action of friction force; optionally, the first and second conveying elements are also provided with protrusions and grooves, and the width of the protrusion is slightly larger than the width of the heat shrink tube used, and the same is true for the groove. The purpose of this is that the heat shrink tubes input side by side will only be driven forward by being clamped by the protruding part and the third conveying element 23, while the other heat shrink tubes are located in the groove without contact, and thus will not be driven.

[0042] The guide element includes a shift fork 311 and a guide member 312, the shift fork 311 is arranged on the guide member 312; the shift fork 311 forms a plurality of slide grooves for the heat shrink tube to pass through, and the corresponding guide member 312 forms a plurality of guide holes for the heat shrink tube to pass through, and the on-off control element 32 is arranged on one side of the guide member 312, and the heat shrink tube in the guide hole can be pushed against the side wall of the guide hole through the movable end of the on-off control element 32 to stop the movement of the heat shrink tube; in this technical scheme, the entire switching assembly 3 can be movable in a direction perpendicular to the movement direction of the heat shrink tube, that is, the shift fork 311 first constrains the lateral swing of the heat shrink tube, and the guide member 312 and the opening element 33 further swing in the lateral direction of the heat shrink tube, when the switching drive member 34 causes the aforementioned several elements to move, it will naturally make the required heat shrink tube be aligned with the protrusions and grooves provided on the first and second conveying elements mentioned above, and the whole process is similar to the chain transmission system of a bicycle. The on-off control element 32 may be a cylinder, and the movable end of the cylinder may move back and forth through the side wall of the guide hole to fix the heat shrink tube that does not need to move to prevent misoperation.

[0043] In general, when a heat shrink tube of a specified specification is used, the heat shrink tube is driven to a driving state by the switching component 3, while the unused heat shrink tube is fixed by the on-off control element 32 and is not subjected to a driving force, and is therefore in a stationary state.

[0044] Optionally, the opening element 33 forms a plurality of elliptical through holes, the width of the elliptical through holes is smaller than the width of the heat shrink tube, and the heat shrink tube is squeezed on both sides when passing through the elliptical through holes, so that the heat shrink tube is reduced in width and opens to form a tube. In this technical scheme, the interior of the elliptical through hole is gradually deformed, that is, the heat shrink tube is opened after the two ends of the heat shrink tube are gradually squeezed. The opening element 33 of this scheme is cut from bottom to top using a cutter, and the gradual deformation of the interior of the elliptical through hole forms a contoured incision, which cooperates with the cutting direction of the aforementioned cutter to achieve smooth opening of the flat tube while having a smooth cross-section. In the prior art, this type of cutting method mostly uses a V-shaped cutter to cut from both sides to the center line. Although this method does not require the elliptical internal cavity of the scheme to assist the opening of the heat shrink tube, it will eventually make the cross section uneven. Therefore, after adopting the above technical scheme, the problem of uneven cross section can be solved.

[0045] Marking component 4: forms a mark on the surface of the heat shrink tube; optionally, the marking component 4 includes a marking element 41 and a marking driver 42, and the marking element 41 forms text or patterns on the surface of the heat shrink tube by thermal transfer printing or the like; the marking driver 42 can move along a direction perpendicular to the movement of the heat shrink tube, driving the marking element 41 disposed at the movable end of the marking driver 42 to approach or move away from the heat shrink tube to achieve the effect of printing text or patterns. The specific technical implementation method of the above-mentioned marking is an existing mature technology and will not be elaborated here.

[0046] The sleeve assembly 5 includes an expansion element 51 and a sleeve element 52. After the heat shrink tube is output from the opening element 33, it is sleeved on the expansion element 51. The expansion element 51 drives the heat shrink tube to move to the sleeve element 52. After the sleeve element 52 removes the heat shrink tube from the expansion element 51, it moves and sleeves the heat shrink tube on the wiring harness.

[0047] Therefore, after adopting the above scheme, when the diameter of the heat shrink tube is not much different from the diameter of the wire to be sleeved, the expansion effect of the expansion element 51 can realize the pre-expansion of the heat shrink tube, so that it is easier to sleeve on the wire to be sleeved.

[0048] Optionally, the tube expansion element 51 includes a rotating driving member 511 and a plurality of tube expansion members 512. The tube expansion members 512 are arranged at the rotating end of the rotating driving member 511, thereby driving the long axis of the tube expansion member 512 to point to the movement direction of the heat shrink tube. The tube expansion member 512 is a variable diameter cylinder. The heat shrink tube gradually increases its diameter when it is sleeved on the tube expansion member 512. The rotating driving member 511 rotates after the cutting element 35 cuts off the heat shrink tube, so that the tube expansion member 512 is close to the sleeve element 52.

[0049] Optionally, the sleeve element 52 includes a sleeve driving member 521 and a clamping member 522. The sleeve driving member 521 drives the clamping member 522 to move. The clamping member 522 is provided with a plurality of openable and closable jaws 5221. The jaws 5221 remove the heat shrink tube from the expansion tube element 51 and sleeve it on the wire harness.

[0050] Specifically, the tube expansion element 51 can be formed radially around the rotating axis of the rotating driving member 511, and automatically rotate to the corresponding size according to the specifications of the heat shrink tube. A sensing element can also be set, so that when the aforementioned opening element 33 fails to open the heat shrink tube, it will not be able to be installed on the tube expansion element 51. The sensing element can sense that there is no heat shrink tube growing on the sleeve element 52, and then output an alarm signal; the clamping member 522 clamps the heat shrink tube and then takes it off, and the clamping claw 5221 can form a hexagonal clamping space around it, so that the heat shrink tube that has been opened will not be deformed by clamping again, resulting in failure when the wiring harness is installed. The specific structure of this clamping claw 5221 is similar to a camera shutter, which is also a prior art, so the internal structure will not be repeated. The harness clamping claw is an external device used to fix the harness to achieve the purpose of installing the heat shrink tube. The harness that has completed the installation of the heat shrink tube is taken to the next workstation by the harness clamping claw.
