Description

Technical Field

[0001] This invention relates to an automatic cable end-insulator sleeve mounting system and method, belonging to the technical field of power auxiliary processing equipment. Background Technology

[0002] In on-site power construction and power equipment assembly scenarios, such as the installation of electrical equipment like electricity meters and the assembly of power equipment like pole-mounted switches, a large number of leads are needed to connect the corresponding connection points. Therefore, a large number of leads of different specifications need to be manufactured, with the thickness of the leads determined by the design current required to conduct electricity at the connection point. The lead is a cable of a certain length, with copper lug terminals and insulating sleeves installed at both ends. The length of the lead is determined according to the distance between the connection points. The copper lug terminals are used to fix the connection at the connection point, and the insulating sleeves are used to isolate the exposed parts of the copper lug terminals except for the conductive contact areas.

[0003] Currently, copper lug terminal crimping is typically done manually on-site using a portable terminal crimping machine. The process involves manually attaching the heat-shrinkable insulating sleeve and copper lug to the cable end, then using the crimping machine to tighten and secure the copper lug to the cable end. The heat-shrinkable insulating sleeve is manually cut from the insulating sleeve roll and then attached to the cable end. This cutting and attaching process is inefficient, impacting on-site work progress and representing one of the main challenges in automating lead crimping.

[0004] Therefore, there is an urgent need for a method that can automatically install insulating sleeves at both ends of the cable to improve the installation efficiency of the insulating sleeves at both ends of the cable, in order to automate the production of cable leads and improve the production efficiency of cable connection leads.

Detailed Implementation

[0023] See Figures 1-7 The present invention relates to an automatic cable end insulation sleeve mounting system, comprising a mounting frame 51 and mounting systems 52 symmetrically arranged on the left and right sides of the mounting frame 51; A cable clamping device 8 is provided on the frame 51 between the left and right assembly systems 52, clamping the cable 101 and moving back and forth between the left and right assembly systems 52. The cable clamping device 8 includes a linear base 81 mounted on the frame 51, a linear guide rail 82 fixed on the top surface of the linear base 81, a conveyor belt 83 mounted on both sides of the linear base 81 and controlled by a stepper motor, and two clamping parts 84 slidably mounted on the linear guide rail 82. The clamping parts 84 are driven to move by the conveyor belt 83. The two clamping parts 84 are driven to move by the conveyor belts 83 on both sides, and can move synchronously at the same speed or asynchronously at different speeds. The two clamping parts 84 simultaneously clamp both ends of the cable 101 and move back and forth between the left and right assembly systems 52. The assembly system 52 includes a cutting device 521, a clamping device 522, a cable end guide device 523, and an insulation sleeve installation mechanism 524, all mounted on the assembly workbench 520. First, the cutting device 521 cuts a section of insulation sleeve 103, and then the clamping device 522 delivers the insulation sleeve 103 to the insulation sleeve installation mechanism 524. The cable end guide device 523 guides the exposed conductor portion of the cable 101 into the insulation sleeve installation mechanism 524, and the insulation sleeve installation mechanism 524 then mounts the insulation sleeve 103 onto the cable 101. The cutting device 521 automatically cuts a section of insulating sleeve 103 from the insulating sleeve reel, and includes a material roll support 5211, a reel guide mechanism 5212, a pinch roller 5213, a cutter 5214, and a material table device 5215 mounted on the assembly worktable 520. The material roll support 5211 is used to install the insulating sleeve reel 5216, and includes a support rod 52111 mounted on the assembly worktable 520. A horizontal shaft 52112 is fixed at the free end of the support rod 52111, and a limiting block 52113 is mounted on the horizontal shaft 52112. The material roll 5216 is rotatably mounted on the horizontal shaft 52112 and limited on the horizontal shaft 52112 by the limiting block 52113. The tape guiding mechanism 5212 guides the insulating tape 104 drawn from the reel 5216 to the pinch roller 5213. It includes a transverse guide seat 52121 horizontally mounted on the assembly worktable 520, and longitudinal guide blocks 52123 bolted into through-hole slots 52122 on the transverse guide seat 52121. The distance between the two longitudinal guide blocks 52123 is the width of the insulating tape 104. The pinch roller 5213 actively pulls the insulating tape 104 through the cutter 5214. It includes a driven roller 52131 and a driven roller 52132 positioned vertically. The driven roller 52132 is controlled to rotate by a stepper motor. The roller shaft of the driven roller 52131 is pressed downwards by bolts and springs to control the clamping force between the driven roller 52131 and the driven roller 52132. The cutter 5214 is controlled to rise and fall by a cylinder, cutting a section of insulating sleeve 103 from the insulating tape 104. The material platform device 5215 clamps the cut flat insulating sleeve 103 and opens up the upper and lower layers of the insulating sleeve 103. It includes an upper material platform 52151 and a lower material platform 52152 arranged vertically. The upper material platform 52151 is raised and lowered above the lower material platform 52152 by a screw adjustment mechanism controlled by a stepper motor. Suction cups 52153 are provided on both the upper material platform 52151 and the lower material platform 52152. The suction cups 52153 are connected to a negative pressure pump through pipelines. The upper and lower suction cups 52153 suck up the upper and lower layers of the insulating sleeve 103. The upper material platform 52151 then moves upward a certain distance, thereby opening up the upper and lower layers of the insulating sleeve 103. The clamping and conveying device 522 clamps and conveys the cut insulating sleeve 103 to the insulating sleeve mounting mechanism 524, and includes a clamping arm 5222 mounted on the set worktable 520 by a two-axis manipulator 5221; the inner side of the clamping arm 5222 is provided with a recess, the two clamping arms 5222 are symmetrically arranged and clamped and released by a cylinder; the two-axis manipulator 5221 controls the clamping arm 5222 to move horizontally left and right and move vertically up and down by an electric cylinder; The cable end guiding device 523 guides the end of the cable 101 to the insulation sleeve mounting mechanism 524. It includes a cable end guiding base 5231 mounted on the mounting workbench 520 and cable end guiding arms 5232 symmetrically rotatably mounted on the cable end guiding base 5231. The upper end of the cable end guiding arm 5232 is provided with a semi-conical guide hole, and the lower end is hinged to the movable end of the cylinder through a connecting rod. The cylinder pushes the two cable end guiding arms 5232 to close together to form a conical guide hole. The insulating sleeve installation mechanism 524 fits the insulating sleeve 103 onto the end of the cable 101. It includes an insulating sleeve installation base plate 5241 slidably mounted on the installation worktable 520 via a transverse slide rail 5246, multiple sets of insulating sleeves 5242 of different thicknesses fixedly mounted on the insulating sleeve installation base plate 5241, an insulating sleeve guide rod 5243 slidably disposed within the insulating sleeve 5242, and an insulating sleeve push block 5244 slidably fitted around the outer ring of the insulating sleeve 5242. A conversion electric push cylinder 5247 is hinged between the bottom of the insulating sleeve installation base plate 5241 and the installation worktable 520. According to the thickness of the cable 101, the insulating sleeve installation base plate 5241 is moved by the conversion electric push cylinder 5247 to select a suitable insulating sleeve 5242. The left end of the insulating sleeve guide rod 5243 extends out of the insulating sleeve 5242 to form a tapered portion, and the right end is connected to the movable end of the insulating sleeve guide cylinder 5245, which is set on the insulating sleeve mounting base plate 5241. The tapered portion of the insulating sleeve guide rod 5243 and the left end of the insulating sleeve 5242 can guide the insulating sleeve 103 when it is fitted onto the insulating sleeve 5242. The insulating sleeve push block 5244 is connected to the movable end of the insulating sleeve push cylinder 5248, which is set on the insulating sleeve mounting base plate 5241. The insulating sleeve push block 5244 can push the insulating sleeve 103 fitted onto the insulating sleeve 5242 away from the insulating sleeve 5242.

[0024] The present invention relates to a method for fitting insulation sleeves at both ends of a cable, which is based on the automatic cable end-fitting system described above, and includes the following steps: Step 1: Cut the rolled insulating strip into insulating sleeves 103 using the cutting device 521, and use the suction cup 52153 of the material table device 5215 to hold and open the upper and lower layers of the flat folded insulating sleeve 103. Step 2: The clamping device 522 clamps the insulating sleeve 103 and moves it to the insulating sleeve mounting mechanism 524. The clamping device 522 clamps the insulating sleeve 103 to ensure that it remains in an open state between the upper and lower layers, and then moves it to the end of the insulating sleeve tube 5242 of the insulating sleeve mounting mechanism 524. The insulating sleeve guide rod 5243 of the insulating sleeve mounting mechanism 524 extends out of the end of the insulating sleeve tube 5242 to form a conical head. The clamping device 522 puts the partially opened insulating sleeve 103 onto the insulating sleeve tube 5242 along the conical head. The clamping device 522 releases the insulating sleeve 103 and moves back to the cutting device 521 to clamp the next insulating sleeve 103. Step 3: Place the cable 101 with both ends stripped of insulation on the cable clamping device 8. The cable clamping device 8 clamps the cable 101 and moves it to the right end of the mounting frame 51. The insulating sleeve guide rod 5243 retracts into the insulating sleeve 5242, exposing the inner hole at the end of the insulating sleeve 5242. The cable end guide arm 5232 of the cable end guide device 523 closes, forming a conical guide hole directly in front of the inner hole at the end of the insulating sleeve 5242. The exposed conductive wire at the right end of the cable 101 is guided into the inner hole at the end of the insulating sleeve 5242 through the conical guide hole. The cable end guide arm 5232 of the cable end guide device 523 separates to allow for movement. The cable clamping device 8 clamps the cable 101 and continues to move to the right, sending all the exposed conductive wires at the right end of the cable 101 into the inner hole at the end of the insulating sleeve 5242. Step 4: The insulating sleeve installation mechanism 524 puts the insulating sleeve 103 onto the right end of the cable 101; the insulating sleeve pusher 5244 on the insulating sleeve tube 5242 moves to the left, pushing the insulating sleeve 103 put on the insulating sleeve tube 5242 in step 3 onto the cable 101, thus completing the installation of the insulating sleeve 103 on the right end of the cable 101. Step 5: The cable clamping device 8 clamps the cable 101 and moves it to the left end of the mounting frame 51. The mounting system 52 at the left end completes the mounting of the insulation sleeve 103 on the left end of the cable 101 through the above steps one to four.

[0025] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
