Description

Technical Field

[0001] The present invention relates to the technical field of power cable processing, and in particular to a cable terminal sleeve heat shrinking machine, a heat shrinking method and cable production equipment. Background Art

[0002] During the processing of power cables, a series of steps need to be completed, including wire feeding and cutting, position labeling, wire tube printing and testing, heat shrink tube wearing, terminal crimping testing, tube heat shrinking, cable pre-storage, bundle rolling and bundling. After the terminal crimping test, the wiring tube or heat shrink tube needs to be heat shrunk at the specified position. However, the wiring tube or heat shrink tube is put on the cable before the terminal is crimped.

[0066] The present invention will be further described below in conjunction with the accompanying drawings.

[0067] During the processing of power cables, a series of steps need to be completed, including wire feeding and cutting, position labeling, wire tube printing and testing, heat shrink tube wearing, terminal crimping testing, tube heat shrinking, cable pre-storage, bundle rolling and bundling. After the terminal crimping test, the wiring tube or heat shrink tube needs to be heat shrunk at the specified position. However, the wiring tube or heat shrink tube is put on the cable before the terminal is crimped. During the crimping and transportation process, since the wiring tube or heat shrink tube is in a loose state before heat shrinking, its position changes, causing it to deviate from the connection of the cable. At this time, it is transmitted to the heat shrink equipment for heat shrinking operation, which will cause the wiring tube or heat shrink tube to not be fastened to the connection of the cable, and the heat shrinkage fails.

[0068] Embodiment 1

[0069] like Figure 1 , Figure 2 As shown, in order to solve the above-mentioned technical problems, an embodiment of the present application provides a cable terminal sleeve heat shrink machine, including a translation device 10, a positioning device 20, a sleeve retraction device 30 and a heat shrink device 40; the positioning device 20 is movably arranged on the translation device 10, and the positioning device 20 is used to fix the cable 50 to be processed and can move under the drive of the translation device 10; the sleeve retraction device 30 is arranged on the moving path of the positioning device 20 to push the heat shrink tube of the cable 50 to be processed on the positioning device 20 to the heat shrink position; the heat shrink device 40 is arranged on the moving path of the positioning device 20 to shrink the heat shrink tube of the cable 50 to be processed on the positioning device 20 to the heat shrink position.

[0070] As can be seen from the above, by setting the positioning device 20 to fix the cable 50 to be processed, the cable 50 to be processed is prevented from being offset during the processing, and the sleeve return device 30 and the heat shrink device 40 are set on the moving path of the positioning device 20 to realize the switching and docking of each process and improve the degree of automation. The positioning device 20 is driven to move by the translation device 10, so that the cable 50 to be processed on the positioning device 20 passes through the sleeve return device 30 and the heat shrink device 40 in sequence after being fixed, so that after the sleeve return device 30 moves the heat shrink tube to the heat shrink position, heat shrinkage is performed again, ensuring that the heat shrink tube can be heat-shrunk at the heat shrink position, realizing automatic heat shrinkage, and improving processing efficiency.

[0071] It should be noted that if Figure 5 As shown, the cable 50 to be processed includes a terminal section 510 and two branch sections 520, the terminal section 510 is perpendicular to the branch section 520, a terminal is provided at one end of the terminal section 510, and the heat shrink position is a part of the heat shrink tube wrapped around the terminal; Figure 1 As shown, the terminal segment 510 is parallel to the Y direction, and the branch segment 520 is parallel to the X direction.

[0072] It should also be noted that the translation device 10 is a linear module, for example, a screw linear module, a belt slide linear module, and its specific structure is prior art and will not be described in detail in this application.

[0073] It should also be noted that if Figure 1 As shown, the moving path of the positioning device 20 is parallel to the X direction.

[0074] Embodiment 2

[0075] like Figure 1 , Figure 2 As shown, the cable terminal sleeve heat shrink machine includes a translation device 10, a positioning device 20, a sleeve retracting device 30 and a heat shrinking device 40; the positioning device 20 is movably arranged on the translation device 10, and the positioning device 20 is used to fix the cable 50 to be processed and can move under the drive of the translation device 10; the sleeve retracting device 30 is arranged on the moving path of the positioning device 20 to move the heat shrink tube of the cable 50 to be processed on the positioning device 20 to the heat shrink position; the heat shrinking device 40 is arranged on the moving path of the positioning device 20 to shrink the heat shrink tube of the cable 50 to be processed on the positioning device 20 to the heat shrink position.

[0076] As can be seen from the above, by setting the positioning device 20 to fix the cable 50 to be processed, the cable 50 to be processed is prevented from being offset during the processing, and the sleeve return device 30 and the heat shrink device 40 are set on the moving path of the positioning device 20 to realize the switching and docking of each process and improve the degree of automation. The positioning device 20 is driven to move by the translation device 10, so that the cable 50 to be processed on the positioning device 20 passes through the sleeve return device 30 and the heat shrink device 40 in sequence after being fixed, so that after the sleeve return device 30 moves the heat shrink tube to the heat shrink position, heat shrinkage is performed again, ensuring that the heat shrink tube can be heat-shrunk at the heat shrink position, realizing automatic heat shrinkage, and improving processing efficiency.

[0077] It should be noted that if Figure 5 As shown, the cable 50 to be processed includes a terminal section 510 and two branch sections 520, the terminal section 510 is perpendicular to the branch section 520, a terminal is provided at one end of the terminal section 510, and the heat shrink position is a part of the heat shrink tube wrapped around the terminal; Figure 1 As shown, the terminal segment 510 is parallel to the Y direction, and the branch segment 520 is parallel to the X direction.

[0078] It should also be noted that the translation device 10 is a linear module, for example, a screw linear module, a belt slide linear module, and its specific structure and working principle are all existing technologies and will not be repeated in this application.

[0079] It should also be noted that if Figure 1 As shown, the moving path of the positioning device 20 is parallel to the X direction.

[0080] like Figure 3 , Figure 4 As shown, in some embodiments, the sleeve retracting device 30 includes a sleeve moving assembly 310, a sliding seat 320 and a toggle member 330; the sliding seat 320 is movably disposed on the sleeve moving assembly 310; the toggle member 330 is disposed on the sliding seat 320; wherein the sleeve moving assembly 310 drives the sliding seat 320 to move along the terminal section 510 of the cable 50 to be processed, so that the toggle member 330 moves and pulls the heat shrink tube to the heat shrink position.

[0081] When the translation device 10 drives the positioning device 20 to move to the sleeve retracting device 30, the cable 50 to be processed is located above the sleeve moving assembly 310, and the sleeve moving assembly 310 drives the sliding seat 320 to move along the terminal section 510 of the cable 50 to be processed, and the toggle member 330 moves with the sliding seat 320. Since the heat shrink tube is sleeved on the cable 50 to be processed, the toggle member 330 will abut against the heat shrink tube during the process of moving along the terminal section 510 of the cable 50 to be processed, and drive the heat shrink tube to move until the heat shrink tube is moved to the heat shrink position, ready for heat shrinkage.

[0082] It should be noted that the sleeve moving assembly 310 is a linear module, for example, a screw linear module, a belt slide linear module, and its specific structure and working principle are all existing technologies and will not be repeated in this application.

[0083] like Figure 3 , Figure 4 As shown, in some embodiments, the toggle member 330 includes a base 3301, a first movable clamp block 3302, a second movable clamp block 3303 and a driving unit; the base 3301 is arranged on the sliding base 320, and a slide groove is arranged on the top of the base 3301; the first movable clamp block 3302 is movably arranged in the slide groove; the second movable clamp block 3303 is movably arranged in the slide groove, and the second movable clamp block 3303 is arranged opposite to the first movable clamp block 3302; the driving unit is arranged on the base 3301, and the driving unit is respectively connected to the first movable clamp block 3302 and the second movable clamp block 3303; wherein the driving unit drives the first movable clamp block 3302 and the second movable clamp block 3303 to move toward or away from each other, so that the distance between the first movable clamp block 3302 and the second movable clamp block 3303 is reduced or increased.

[0084] The first movable clamp 3302 and the second movable clamp 3303 are driven to move by the driving unit, and the movement directions of the first movable clamp 3302 and the second movable clamp 3303 are opposite, so as to adjust the distance between the first movable clamp 3302 and the second movable clamp 3303, so as to ensure that the adjusted first movable clamp 3302 and the second movable clamp 3303 can abut against the toggle block, and adapt to a variety of cables 50 and heat shrink tubes of different specifications and sizes to be processed. When the driving unit drives the first movable clamp 3302 and the second movable clamp 3303 to move toward each other, the distance between the first movable clamp 3302 and the second movable clamp 3303 is reduced; when the driving unit drives the first movable clamp 3302 and the second movable clamp 3303 to move in opposite directions, the distance between the first movable clamp 3302 and the second movable clamp 3303 is increased.

[0085] It should be noted that since the heat shrink process is carried out after the crimping process, and the width of the terminal segment 510 of the cable 50 to be processed is greater than the cable diameter after the terminal is crimped, an adjustable width toggle member 330 is provided to ensure that the toggle member 330 passes through the terminal smoothly.

[0086] It should also be noted that the driving unit includes a lead screw inserted into the slide groove, the lead screw is rotatably mounted on the base 3301, the lead screw is a bidirectional lead screw, that is, a positive and negative thread lead screw, the first movable clamping block 3302 and the second movable clamping block 3303 are respectively threadedly connected to the lead screw; the driving unit also includes a sleeve drive motor, the sleeve drive motor is arranged on the base 3301, and the rotating shaft of the sleeve drive motor is connected to the lead screw.

[0087] It should also be noted that a V-shaped groove is provided on the first movable clamp block 3302 and the second movable clamp block 3303. In addition, in order to more clearly show the structure of the first movable clamp block 3302 and the second movable clamp block 3303, as shown in FIG. Figure 3 , Figure 4 As shown, the figure also shows a structural schematic diagram when the first movable clamping block 3302 and the second movable clamping block 3303 are not installed on the base 3301.

[0088] It should also be explained that, after the terminal of the cable 50 to be processed is crimped, the translation device 10 moves the cable 50 to be processed on the positioning device 20 to the sleeve return device 30, at which time, the first movable clamp 3302 and the second movable clamp 3303 are in a separated state; the sleeve moving assembly 310 moves the sliding seat 320 to the end of the cable 50 to be processed away from the terminal, and the toggle member 330 moves with the sliding seat 320, and then the driving unit drives the first movable clamp 3302 and the second movable clamp 3303 to move toward each other, and the first movable clamp 3302 and the second movable clamp 3303 are in a separated state. The distance is reduced, and the distance is slightly larger than the cable diameter; then the sleeve moving assembly 310 moves toward the end of the cable 50 to be processed where the terminal is provided, and the toggle member 330 moves with the sliding seat 320, and the toggle member 330 moves the heat shrink tube close to the terminal, and the heat shrink tube wraps a part of the terminal, that is, the heat shrink position; at this time, the driving part drives the first movable clamp block 3302 and the second movable clamp block 3303 to move in opposite directions, and the distance between the first movable clamp block 3302 and the second movable clamp block 3303 increases, and the sleeve moving assembly 310 drives the sliding seat 320 and the toggle member 330 to leave the cable 50 to be processed.

[0089] like Figure 5 , Figure 6 As shown, in some embodiments, the positioning device 20 includes a base plate 210, two clamps 220 and a positioning plate 230; the base plate 210 is movably disposed on the translation device 10; the two clamps 220 are disposed on the base plate 210, the two clamps 220 are vertically arranged, and the two clamps 220 are respectively used to fix the terminal segment 510 and the branch segment 520 of the cable 50 to be processed; the positioning plate 230 is disposed on the base plate 210, and the positioning plate 230 is parallel to the branch segment 520 of the cable 50 to be processed.

[0090] Two clamps 220 are provided to respectively fix the terminal section 510 and one of the branch sections 520 of the cable 50 to be processed, thereby achieving fixation of the cable 50 to be processed, and the positioning plate 230 is used to limit the other branch section 520 of the cable 50 to be processed.

[0091] It should be noted that if Figure 1 As shown, the positioning plate 230 is parallel to the X direction.

[0092] like Figure 5 , Figure 6 As shown, in some embodiments, the clamping member 220 includes a base box 2202, a clamping rod, a clamping plate 2201 and a clamping driving member; a positioning groove 2203 is provided on the top of the base box 2202, and a through hole connected to the positioning groove 2203 is provided on the side of the base box; the clamping rod is movably arranged in the through hole; the clamping plate 2201 is arranged at one end of the clamping rod and is located in the through hole; the clamping driving member is arranged on the base box 2202, and the telescopic rod of the clamping driving member is connected to the end of the clamping rod away from the clamping plate 2201.

[0093] The telescopic rod of the clamping driving member is extended and retracted to drive the clamping plate 2201 to move, so that the fixing plate and the bottom plate 210 cooperate to clamp the cable 50 to be processed.

[0094] It should be noted that the clamping drive component includes but is not limited to one of a pneumatic cylinder, an oil cylinder and an electric push rod.

[0095] It should also be noted that a V-shaped groove is provided on the clamping plate 2201 .

[0096] like Figure 7 , Figure 8 As shown, in some embodiments, the heat shrink device 40 includes a shell 410, a fan 420 and an electric heater; a heat shrink port 4101 is provided on the side of the shell 410 close to the translation device 10; the fan 420 is provided at the top of the shell 410; the electric heater is provided inside the shell 410; wherein, the top surface and the bottom surface of the heat shrink port 4101 are respectively provided with a plurality of air outlets 4102 to communicate with the interior of the shell 410.

[0097] The air blown out by the fan 420 is heated by an electric heater to form hot air for heat shrinkage, and the hot air enters the heat shrink opening 4101 through the air outlet 4102 to heat shrink the cable 50 to be processed in the heat shrink opening 4101.

[0098] like Figure 7 , Figure 8 As shown, in some embodiments, the heat shrink device 40 also includes a movable baffle 440 and an opening and closing part; the movable baffle 440 is rotatably disposed on both sides of the heat shrink opening 4101; the opening and closing part is disposed on both sides of the shell 410, and the opening and closing part drives the movable baffle 440 to rotate so that the movable baffle 440 blocks or opens both sides of the heat shrink opening 4101.

[0099] When heat shrinking the cable 50 to be processed in the heat shrink opening 4101, the opening and closing portion is provided to drive the movable baffle 440 to rotate, thereby blocking both sides of the heat shrink opening 4101, so that the hot air in the heat shrink opening 4101 circulates in a relatively closed area and quickly fills the heat shrink opening 4101, thereby ensuring the heat shrinking effect.

[0100] It should be noted that the movable baffle 440 can be rotatably connected to the heat shrink opening 4101 in a hinged manner.

[0101] In some embodiments, the opening and closing part includes a rotating shaft, a driven gear, an opening and closing motor and a driving gear; the rotating shaft is connected to the movable baffle 440; the driven gear is arranged on the rotating shaft; the opening and closing motor is arranged in the shell 410; the driving gear is arranged on the rotating shaft of the opening and closing motor, and the driving gear is meshed with the driven gear.

[0102] The opening and closing motor drives the driving gear to rotate, the driving gear meshes with the driven gear, the driven gear rotates, thereby driving the shaft to rotate, and the movable baffle 440 rotates with the shaft, so that the movable baffle 440 blocks or opens the two sides of the heat shrink opening 4101.

[0103] It should be noted that before the heat shrink device 40 is heat-shrunk, the movable baffle 440 opens both sides of the heat shrink opening 4101 , and the cable 50 to be processed moves in and out from both sides of the heat shrink opening 4101 along with the positioning device 20 under the action of the translation device 10 .
