[0031] In order to better understand the purpose, structure and function of the present invention, an automatic wire stripping device of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 2 As shown, the present application provides an automatic wire stripping device for separating the wire core and wire sheath of an air conditioner power connection line, and includes an introduction mechanism 1, a wire cutting mechanism 2 and a wire winding mechanism 3 along the transmission direction of the wire to be stripped. The wire cutting mechanism 2 includes at least one group of tool holders 23, and each group of tool holders 23 includes a pair of tool holders 23. The pair of tool holders 23 are symmetrically arranged on both sides of the wire to be stripped. The tool holders 23 are respectively connected to the telescopic mechanism 24. A tool 234 is provided in the tool holder 23, and the tool 234 is connected to the displacement mechanism. The displacement mechanism controls the movement of the tool 234 to contact the wire sheath and divide the wire sheet into two parts.

[0033] like Figure 3-Figure 4As shown, the introduction mechanism 1 includes a fixed introduction wheel 11 and a lifting introduction wheel 12, and wheel axles are respectively arranged at both ends of the fixed introduction wheel 11 and both ends of the lifting introduction wheel 12. The wheel axles of the fixed introduction wheel 11 are rotatably fixed on the frame, and one of the wheel axles of the fixed introduction wheel 11 passes through the frame and is connected to a first motor 13, which is fixed to the frame. The frame is a U-shaped structure with an opening downward, and the fixed introduction wheel 11 and the lifting introduction wheel 12 are both arranged on the side walls of the frame, and knurling is arranged in the middle of the fixed introduction wheel 11, and knurling is arranged in the middle of the lifting introduction wheel 12, and the wheel axles of the lifting introduction wheel 12 are respectively connected to the lifting mechanism 14, and a first proximity switch 15 is arranged on the frame on one side of the fixed introduction wheel 11, and the first proximity switch 15 and the first motor 13 are electrically connected to the controller. The wire to be stripped is inserted between the fixed introduction wheel 11 and the lifting introduction wheel 12 and is pressed by the knurling. After the first proximity switch 15 detects that the wire to be stripped is introduced, the controller turns on the first motor 13, and the first motor 13 drives the fixed introduction wheel 11 to rotate, and the wire to be stripped moves under the drive of the introduction wheel. At the same time, the wire to be stripped drives the lifting introduction wheel 12 to rotate in the opposite direction of the fixed introduction wheel 11, thereby realizing the automatic introduction of the wire to be stripped. Since the distance between the lifting introduction wheel 12 and the fixed introduction wheel 11 is adjustable, the mechanism can realize the stripping operation of air conditioner power connection wires with various wire diameters.

[0034] The lifting device includes a lifting plate 142 for fixing the lifting introduction wheel 12, a screw pair 143 is arranged at the center of the lifting plate 142, the screw pair 143 is screwed on the screw 141, the top of the screw 141 is fixed on the driving shaft of the lifting motor 145, and connecting rods 146 are arranged at opposite ends of the lifting plate 142. The ends of the wheel shaft of the lifting introduction wheel 12 are rotatably fixed on the mounting block 148 through the bearing, and the mounting block 148 is movably sleeved on the connecting rod 146. A through hole for accommodating the connecting rod 146 is provided on the mounting block 148 in a direction perpendicular to the wheel axle, a fastener is provided on the connecting rod 146 on the bottom surface of the mounting block 148, a spring 147 is sleeved on the connecting rod 146 between the mounting block 148 and the lifting plate 142, and slide rails 144 are respectively provided on the inner walls of the frame on both sides of the lifting plate 142, and the lifting plate 142 and the mounting block 148 are slidably connected with the slide rails 144, and the slide rails 144, the connecting rod 146 and the axis of the lead screw 141 are parallel. By movably sleeved the mounting block 148 on the connecting rod 146 and by the action of the spring 147, the wires to be stripped of different wire diameters can pass through the introduction mechanism 1 more smoothly, and this structure plays a role of fine adjustment.

[0035] like Figure 5As shown, the tangent mechanism 2 also includes a bottom plate 21, and multiple groups of limit blocks 22 are arranged on the bottom plate 21 on both sides of the wire to be stripped. A limit groove for the knife holder 23 to move is arranged between adjacent limit blocks 22 on one side of the wire to be stripped. The telescopic mechanism 24 is arranged at the end of the bottom plate 21 away from the limit blocks 22, and a gap is formed between each pair of limit blocks 22 for the wire to be stripped to pass through. A guide tube 25 is arranged on the bottom plate 21 at the outlet end of the wire to be stripped, and a second proximity switch 26 is arranged on one side of the guide tube 25. In order to ensure the efficiency of the tangent mechanism 2, different groups of knives 234 have different adjustment ranges, so as to adapt to the stripping operation of wires with different wire diameters.

[0036] like Figure 6-Figure 8 As shown, each tool holder 23 includes a shell 231 with an opening facing downward, a telescopic mechanism 24 is connected to the top surface of the shell 231, and notches for the wires to be stripped are respectively arranged on the side walls opposite to the bottom surface of the shell 231. The tool 234 is placed in the shell 231, and the tool 234 is fixed on the tool handle 233. The end of the tool handle 233 is connected to the displacement mechanism so that the tool 234 can adapt to the stripping operation of wires with different wire diameters.

[0037] The displacement mechanism includes a driven gear 235, a thread is set on the inner wall of the driven gear 235, a thread is set on the top of the handle 233, the driven gear 235 is screwed on the handle 233, a cutting table is set on the top of the handle 233, a guide hole matching the top of the handle 233 is set in the shell 231, and an avoidance hole 232 for the driven gear 235 to be exposed is set on the side wall of the shell 231, the avoidance hole 232 is connected with the guide hole, the driven gear 235 is meshed with the driving gear 236 outside the avoidance hole 232, and the driving gear 236 is fixed on the driving shaft of the second motor 237.

[0038] The telescopic mechanism 24 can be a micro cylinder, a screw nut transmission mechanism or other linear transmission mechanism that can realize the translation of the housing 231. In this solution, the telescopic mechanism 24 is a micro cylinder. When the wire to be stripped is transmitted to the wire cutting mechanism 2, the micro cylinder controls its driving rod to extend, thereby driving the housing 231 to move in the limit groove, so that the housings 231 on both sides are in contact, and then the second motor 237 is turned on, and the second motor 237 rotates to drive the driving gear 236 to rotate, and then drives the driven gear 235 to rotate. The driven gear 235 rotates to drive the handle 233 and the tool 234 to move toward the wire to be stripped and contact the wire skin, thereby realizing the wire skin cutting operation of the wire to be stripped.

[0039] like Fig. 9As shown, the wire cutting mechanism 2 also includes a driving wheel 238 disposed in the tool holder 23. The driving wheels 238 in each pair of tool holders 23 are disposed opposite to each other and clamp the wire to be stripped to provide power for the transmission of the wire to be stripped. Two driving wheels 238 are disposed in each tool holder 23, which are disposed in the tool holders 23 upstream and downstream of the tool 234, respectively. The wire to be stripped contacts the driving wheels 238 on both sides of the tool 234 in each pair of tool holders 23. The axle on one side of the driving wheel 238 extends out of the housing 231 and is connected to a driving motor, which is fixed to the housing 231.

[0040] After the power cord is cut by the cutter 234, it passes through the guide tube 25 and flows to the winding mechanism 3. When the second proximity switch 26 detects that the power cord has been cut, the winding mechanism 3 is started. Fig.10 As shown, the wire winding mechanism 3 includes three groups of curling parts with the same structure, namely a wire core curling part 31 and two groups of wire skin curling parts 32. The axis lines of the two groups of wire skin curling parts 32 are parallel to the transmission direction of the wire to be stripped. The wire core curling part 31 is arranged between the two groups of wire skin curling parts 32, and the axis line of the wire core curling part 31 is perpendicular to the transmission direction of the wire to be stripped.

[0041] Each group of curling parts includes a rotating shaft 315 and a first roller 311 and a second roller 312 arranged on the rotating shaft 315. The first roller 311 is detachably fixed to one end of the rotating shaft 315. The second roller 312 is slidably arranged on the rotating shaft 315 close to the first roller 311. The second roller 312 is sleeved with a piston rod 313 on the rotating shaft 315 away from the first roller 311. The end of the piston rod 313 is connected to the wire pressing cylinder 314 to control the distance between the first roller 311 and the second roller 312. The other end of the rotating shaft 315 is connected to the third motor 316, and the third motor 316 is fixed on the housing of the wire stripping device. When the wire core or wire sheath reaches the curling part, the wire pressing cylinder 314 drives the piston rod 313 to extend, and the piston rod 313 pushes the second roller 312 to move toward the first roller 311, and makes its end face contact with the end face of the first roller 311 and presses the front end of the wire core or wire sheath. At this time, the third motor 316 is turned on to drive the rolling rotation, thereby realizing the curling of the wire core or wire sheath.

[0042] In addition, the wire winding mechanism 3 also includes a wire clamp assembly 33 for stripping the wire sheath from the wire core and guiding it to the wire sheath curling portion 32 . The wire clamp assembly 33 includes at least one group and is arranged below the wire sheath curling portion 32 .

[0043] The wire clamp assembly 33 includes a first clamping jaw 331 and a second clamping jaw 332 which are hinged together in the middle. The first clamping jaw 331 and the second clamping jaw 332 close to the wire core curling portion 31 form a clamping portion for clamping the wire skin. The other end of the first clamping jaw 331 is connected to the wire clamp cylinder 334. The bottom end of the wire clamp cylinder 334 is fixed on the translation slider 335. A guide rail 336 is provided on the casing. The translation slider 335 is slidably provided on the guide rail 336. The other end of the second clamping jaw 332 is connected to the telescopic cylinder 333. The end of the telescopic cylinder 333 is fixed on the casing. The axis of the telescopic cylinder 333 is parallel to the axis of the guide rail 336 and is perpendicular to the axis of the wire skin curling portion 32. A color sensor 34 is arranged above the first roller 311 of the wire skin curling part 32 for detecting whether the wire skin enters the wire skin curling part 32. A proximity switch is arranged above the first roller 311 of the wire core curling part 31 for detecting whether the wire core enters the wire core curling part 31, thereby controlling the start and stop of the corresponding wire pressing cylinder 314 and the third motor 316.

[0044] In addition, the wire stripping device also includes a control mechanism on one side of the introduction mechanism 1 and the wire cutting mechanism 2. The control mechanism includes an electric control cabinet, a control circuit board is arranged in the electric control cabinet, and an operation panel is arranged on the electric control cabinet. A start button, a stop button, a flip button, a reset button, an emergency stop switch, etc. are arranged on the operation panel, and each button is electrically connected to the control circuit board. An audible and visual alarm light is also arranged on the electric control cabinet, and the audible and visual alarm light is electrically connected to the control circuit board. A power cord placement box is arranged on one side of the electric control cabinet for placing the power cord to be stripped.

[0045] The stripping device realizes automatic introduction of the wire to be stripped through the introduction mechanism. The introduction wheel is connected with the screw 141 nut transmission mechanism and the fine adjustment mechanism to adapt to the introduction of wires with different wire diameters. The tangent mechanism 2 is composed of multiple sets of tool holders 23 with adjustable tool 234 heights. Each set of tool holders 23 is symmetrically arranged on both sides of the wire to be stripped to divide the outer skin of the wire to be stripped into two parts. The tool 234 is retractable and replaceable. The tool holder 23 at the bottom of the tool 234 is provided with a driving wheel 238. Different tool holders 23 have different lifting ranges to meet the needs of cutting wires with different wire diameters. The winding mechanism 3 uses a separate roller to roll up the wire skin and the wire core, and uses a wire clamp to clamp and separate the wire skin and the wire core, which is conducive to the fixing and guiding of the wire skin. The device has a high degree of automation and greatly reduces labor intensity. The quality of wire stripping is improved, and the wire core is effectively prevented from being damaged.
