Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to an automatic wire stripping and twisting machine. Background Technology

[0002] Wire stripping and twisting is a fundamental skill in electronics and electrical engineering. It involves using wire strippers to remove the insulation from the ends of wires and then twisting the exposed wires as needed to facilitate connections, soldering, or insertion into terminals, thereby ensuring reliable circuit connections and stable electrical performance. This process requires the operator to be proficient in tool use and wire handling techniques to guarantee wire integrity and connection quality.

[0003] In existing wire handling processes, the insulation layer of the wire is usually stripped manually with hand-held wire strippers, and then the wire is twisted manually to facilitate subsequent operations such as connection, soldering, or insertion of terminals. However, this traditional method has obvious shortcomings: First, stripping and twisting the wire need to be completed in two separate steps, which is inefficient; second, when twisting the wire manually, it is difficult to control the force and angle precisely, which can easily lead to damage to the wire or hand injury. Utility Model Content

[0004] One objective of this invention is to provide an automatic wire stripping and twisting machine. This invention addresses the problem mentioned in the background that in existing wire processing, manual wire strippers are typically used to first strip the insulation layer of the wire, and then the wire is manually twisted to facilitate subsequent connection, soldering, or terminal insertion. However, this traditional method has significant drawbacks: firstly, wire stripping and twisting need to be completed in two separate steps, resulting in low efficiency; secondly, when manually twisting the wire, it is difficult to precisely control the force and angle, which can easily lead to wire damage or hand injury.

[0005] An automatic wire stripping and twisting machine according to an embodiment of the present utility model includes:

[0006] Handheld components, including a handle and a protective sleeve;

[0007] A wire stripping mechanism, installed inside the protective cylinder of the handheld assembly, is used to strip the insulation layer of the wire. The wire stripping mechanism includes a support plate, a sliding plate movably mounted on one side of the support plate via a first slide rail, and a movable plate movably mounted on one side of the sliding plate via a second slide rail. A first connecting rod is symmetrically rotatably mounted on one side of the movable plate, and a first clamping rod is rotatably mounted at one end of the first connecting rod. A wire stripping blade is fixedly mounted at the end of the first clamping rod. The movable plate uses a drive assembly to strip the insulation layer of the wire using the first clamping rod and the wire stripping blade.

[0008] The wire twisting mechanism is installed on both sides of the support plate in the wire stripping mechanism to twist the exposed wire. The wire twisting mechanism includes a second clamping rod and a servo motor fixed between the hand handle and the protective cylinder. The second clamping rod is rotatably set with the support plate through a second positioning shaft. A lever is fixedly set at one end of the second clamping rod, and an elastic pressure column is movably set at the end of the second clamping rod near the wire stripping blade. The second clamping rod is connected to the support plate through a reset assembly.

[0009] Preferably, a battery pack and a control button are fixedly installed at the end and top of the hand handle, respectively, and a slag discharge cylinder is fixedly installed at the bottom of the protective cylinder, with a plug engaged at the bottom of the slag discharge cylinder.

[0010] Preferably, the first clamp is rotatably positioned on one side of the slide via a first positioning shaft.

[0011] Preferably, the drive assembly includes a first electric pusher cylinder and a second electric pusher cylinder. The first electric pusher cylinder is fixedly disposed inside the support plate, and a pusher plate is fixedly disposed at the output end of the first electric pusher cylinder. The second electric pusher cylinder is fixedly disposed inside the pusher plate at one end near the moving plate.

[0012] Preferably, the second electric push cylinder and the movable plate are fixedly arranged.

[0013] Preferably, a trigger switch is fixedly installed inside the support plate at one end near the push plate.

[0014] Preferably, the lever and the slide plate correspond to each other, the elastic pressure column is composed of two parts: a spring and a pressure column, and an anti-slip clamp is fixedly provided at the bottom of the elastic pressure column.

[0015] Preferably, the reset assembly includes a second connecting rod rotatably disposed inside the second clamping rod, and a reset block movably disposed inside the support plate. The second connecting rod and the reset block are rotatably disposed together, and a reset spring is fixedly disposed between the reset block and the support plate.

[0016] The beneficial effects of this utility model are:

[0017] This invention effectively avoids the problems of low efficiency and uneven force control leading to wire damage or hand injury caused by traditional manual step-by-step operation through its wire stripping and twisting mechanisms. In use, the operator inserts the wire into the protective cylinder and then activates the first electric pusher cylinder in the drive assembly. The first electric pusher cylinder pulls the push plate, causing the slide plate to move along the first slide rail to the position of the wire. At this time, the second electric pusher cylinder pushes the moving plate to slide along the second slide rail, driving the first clamping rod and wire stripping blade to lock inwards via the first connecting rod, cutting into the wire insulation layer. Then, the first electric pusher cylinder is driven again to push outwards, causing the wire stripping blade to peel off the insulation layer on the wire. When the slide plate returns to its original position, it squeezes the lever at the end of the second clamping rod in the twisting mechanism, causing the second clamping rod, connected to the second positioning shaft, to push the clamping plate to hold the exposed wire. Simultaneously, the slider contacts the trigger switch, activating the servo motor, causing the protective cylinder to rotate and the twisting mechanism to rotate. Thus, wire can be twisted while stripping, effectively ensuring consistent stripping depth and accurate twisting angle, improving processing quality and safety.

[0018] This utility model features a handheld component. When in use, the operator holds the handle and starts the device via a control button. The battery pack powers the electric push cylinder and servo motor. A protective sleeve covers the wire stripping blade and twisting mechanism to prevent accidental contact with sharp parts during operation. Stripped insulation debris is collected through a slag discharge cylinder, and the plug is removable for easy cleaning, thus giving the device the advantage of convenience.

[0026] refer to Figure 1-4 An automatic wire stripping and twisting machine, comprising:

[0027] Handheld component 1 includes a hand handle 101 and a protective sleeve 104;

[0028] The wire stripping mechanism 2, installed inside the protective cylinder 104 of the handheld assembly 1, is used to strip the insulation layer of the wire. The wire stripping mechanism 2 includes a support plate 201. A slide plate 203 is movably mounted on one side of the support plate 201 via a first slide rail 202. A movable plate 207 is movably mounted on one side of the slide plate 203 via a second slide rail 208. A first connecting rod 209 is symmetrically rotatably mounted on one side of the movable plate 207. A first clamping rod 210 is rotatably mounted at one end of the first connecting rod 209. A wire stripping blade 211 is fixedly mounted at the end of the first clamping rod 210. The movable plate 207 uses a drive assembly to strip the wire insulation layer using the first clamping rod 210 and the wire stripping blade 211. The drive assembly includes... The system includes a first electric pusher cylinder 204 and a second electric pusher cylinder 206. The first electric pusher cylinder 204 is fixedly installed inside the support plate 201, and a pusher plate 205 is fixedly installed at the output end of the first electric pusher cylinder 204. The second electric pusher cylinder 206 is fixedly installed inside the pusher plate 205 at one end near the moving plate 207. When the first electric pusher cylinder in the drive assembly is activated, it pulls the pusher plate and moves the slide plate along the first slide rail to the position of the wire. At this time, the second electric pusher cylinder pushes the moving plate to slide along the second slide rail. Through the first connecting rod, it drives the first clamping rod and the wire stripping blade to lock inward and cut into the insulation layer of the wire. Then, the first electric pusher cylinder is driven again to push outward, so that the wire stripping blade peels off the insulation layer on the wire.

[0029] The wire twisting mechanism 4 is installed on both sides of the support plate 201 in the wire stripping mechanism 2, and is used to twist the exposed wire. The wire twisting mechanism 4 includes a second clamping rod 401 and a servo motor 409 fixed between the handle 101 and the protective cylinder 104. The second clamping rod 401 is rotatably connected to the support plate 201 via a second positioning shaft 402. A lever 403 is fixedly installed at one end of the second clamping rod 401, and an elastic pressure column 404 is movably installed at the end of the second clamping rod 401 near the wire stripping blade 211. The second clamping rod 401 is connected to the support plate 201 via a reset assembly. The reset assembly includes a second connecting rod 406 rotatably installed inside the second clamping rod 401, and a servo motor 409 fixed to the handle 101 and the protective cylinder 104. A reset block 407 is movably installed inside the support plate 201. The second connecting rod 406 and the reset block 407 are rotatably connected. A reset spring 408 is fixedly installed between the reset block 407 and the support plate 201. Through the reset assembly, the second clamping rod and the anti-slip clamping plate can be reset after the wire is stripped and twisted, making it convenient to process the next wire. When the slide plate is reset, it squeezes the lever at the end of the second clamping rod in the twisting mechanism, so that the second clamping rod pushes the clamping plate to clamp the exposed wire under the connection of the second positioning shaft. At the same time, the slider contacts the trigger switch and starts the servo motor, so that its protective cylinder drives the twisting mechanism to rotate, thus allowing the wire to be twisted at the same time as stripping.

[0030] Example 1: A battery pack 102 and a control button 103 are fixedly installed at the end and top of the hand handle 101, respectively. A slag discharge cylinder 105 is fixedly installed at the bottom of the protective cylinder 104. A plug 106 is engaged at the bottom of the slag discharge cylinder. The operator holds the hand handle and starts the equipment by controlling the button. The battery pack powers the electric push cylinder and servo motor. The protective cylinder covers the wire stripping blade and the wire twisting mechanism to prevent accidental contact with sharp parts during operation. The stripped insulation debris is collected in a concentrated manner through the slag discharge cylinder. The plug is removable for easy cleaning.

[0031] Example 2: The first clamping rod 210 is rotatably mounted on one side of the slide plate 203 via the first positioning shaft 212. The first positioning shaft ensures the stability of the first clamping rod during rotation. The second electric push cylinder 206 and the moving plate 207 are fixedly mounted. A trigger switch 3 is fixedly mounted inside the support plate 201 near the push plate 205. When the trigger switch is activated, the servo motor starts. When the switch is disengaged, the servo motor stops. The toggle block 403 and the slide plate 203 correspond to each other. The elastic pressure column 404 consists of a spring and a pressure column. An anti-slip clamping plate 405 is fixedly mounted at the bottom of the elastic pressure column 404, which can improve the stability of the wire clamping while the spring allows the anti-slip clamping plate to have self-adaptive ability.

[0032] Working principle: During wire stripping, the first electric pusher cylinder 204 drives the pusher plate 205 to move the slide plate 203 along the first slide rail 202 to the wire position. Subsequently, the second electric pusher cylinder 206 pushes the moving plate 207 to slide along the second slide rail 208. Through the first connecting rod 209, the first clamping rod 210 and the wire stripping blade 211 are locked inward, cutting into the wire insulation layer. The first electric pusher cylinder is driven again to make the wire stripping blade peel off the insulation layer. The stripped debris is collected through the slag discharge cylinder 105. The twisting mechanism 4 twists during wire stripping, and the slide plate returns to its original position. Then, the lever 403 at the tail end of the second clamping rod 401 is squeezed, causing the second clamping rod to push the anti-slip clamping plate 405 along with the second positioning shaft 402 to clamp the exposed wire. After the slider contacts the trigger switch 3, the servo motor 409 is started, driving the protective cylinder 104 and the wire twisting mechanism to rotate, thereby twisting the wire. The reset component includes the second connecting rod 406 and the reset block 407, ensuring that the second clamping rod and the anti-slip clamping plate are reset after the wire processing is completed, which facilitates the processing of the next wire, thereby improving the automation level of wire processing and ensuring the safety and efficiency of the operation.
