[0020] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0021] (1) The present invention is provided with a clamping part. Two groups of clamping parts are started successively, and the interval time between the two is controlled by a single-chip microcomputer control system. After one group of clamping parts is started, the electromagnetic push rod drives the movable mold to slide outward along the slide rail, and the movable mold and the fixed mold are separated from each other, so that the wires can be quickly placed between the movable mold and the fixed mold. When placed, the wires with the insulation stripped off are located outside the movable mold and the fixed mold, and extend to one side above the other group of clamping parts. Since the other group of clamping parts is not started, it is blocked by the limit rod to prevent the wires with the insulation stripped off from falling into the other group of clamping parts. The electromagnetic push rod pushes the movable mold to wrap and clamp the outer side of the wire in a circular manner to prevent the wires from sliding relative to each other when the wires are subsequently cross-tightened, resulting in loose joints between the wires.

[0022] (2) The present invention is provided with an adjustment member and a clamping part. The output shaft of the servo motor drives the bidirectional threaded rod to rotate. The gear meshing drives the two sets of active gears to rotate synchronously. The driving rod drives the U-shaped rod to rotate 90° upward around the inside of the fixed mold. During the upward rotation of the U-shaped rod, the fixed mold and the movable mold are clamped to make the wire bend upward. Since the two sets of U-shaped rods are synchronous, the bending time is saved, the bending accuracy is guaranteed to be synchronized and consistent, and the stability of the subsequent cross tightening of the joint parts is improved. The limit rod plays a limiting and clamping role on the wire to avoid the wire bending angle being too large, which is not conducive to the subsequent grasping of the wiring part. The outer side of the wire slides relative to the outer side of the smooth tube. The smooth tube rotates on the U-shaped rod, which facilitates the rapid bending of the wire, reduces the friction of the smooth tube on the wire, protects the insulation layer on the outside of the wire, and the bent wire is fixedly clamped between the smooth tube and the limit rod to prevent the wire from being unstable and falling.

[0023] (3) The present invention is provided with an adjusting member, a clamping part and a wiring part. The driving motor drives the hollow square tube to rotate clockwise, drives the screw to rotate clockwise through the square block, and the screw rotates clockwise around the internal thread of the inner slider. The screw synchronously rotates clockwise and moves upward, driving the open circular plate and the middle fixed plate to rotate clockwise and move upward synchronously, driving the two groups of exposed wires to quickly cross and tighten together. Since the open circular plate and the middle fixed plate rotate clockwise at a uniform speed, the two groups of exposed wires are evenly and tightly wound together with the fixing of the clamping part. Compared with the traditional manual cross-twisting of the exposed wires together, the driving of the driving motor saves time and effort, and the tightening force is uniform. The two groups of exposed wires are bent by centrifugal force and rub against the open circular plate and the friction rod. The open circular plate and the friction rod generate torque on the two groups of exposed wires and generate upward traction, so that the exposed wires that are continuously tightened under the open circular plate and the friction rod are tightened, avoiding the subsequent loosening of the joints between the wires.

[0024] (4) The present invention is provided with a receiving plate, an open circular plate and a friction rod. After the open circular plate and the friction rod have completed the cross-tightening of the two groups of exposed wires, the tops of the two groups of exposed wires are squeezed by the circular plate, and the open circular plate and the friction rod rotate clockwise to screw the scattered wire heads together again, thus eliminating the trouble of subsequent manual repair. After the two groups of exposed wires have completed the cross-tightening, the open circular plate and the middle fixing plate automatically detach from the tops of the two groups of exposed wires, making it convenient for the two groups of wires to be quickly taken out.

[0025] (5) The present invention is provided with a wrapping piece. When the open circular plate and the middle fixed plate on the wrapping piece rotate clockwise synchronously, a group of wires slide against the outer side of the friction rod. The smooth friction rod reduces the friction force of the exposed wires, and the exposed wires are finally moved to the maximum diameter of the reducer bend rod under force, thereby increasing the support strength of the friction rod for the exposed wires and improving the service life of the friction rod. Another group of wires are forced to fit at the angle between the middle fixed plate and the friction rod. The open circular plate is adapted to the outer side of the anti-slip plate through the special-shaped groove provided inside it. The side of the anti-slip plate close to the middle fixed plate is hidden in the special-shaped groove, thereby preventing the exposed wires from being stuck between the anti-slip plate and the middle fixed plate, so that the two groups of exposed wires are stably cross-tightened.

[0026] (6) The present invention is provided with bolts, square rods and limit plates. The bolts are further tightened on the square rods to make the limit plates fit tightly on the outer ends of the square holes, so that the bolts, the middle fixing plate and the screw rods are combined into a whole. During the use of the wire connection device of the present invention, if the friction rod and the anti-drop plate on one side are damaged or excessively worn, the wrapping piece can be rotated 180° as a whole and reinstalled. At this time, the wrapping piece can continue to be used, which greatly improves the service life of the wrapping piece. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present invention will be further described below in conjunction with the embodiments. Example

[0040] See also Figure 1-9 The present invention provides a technical solution: a wire connection device for electrical production, comprising:

[0041] The operating body 1 includes a base 11, a bidirectional threaded rod 12 rotatably connected to the base 11, and a driving gear 13 meshingly connected to the outside of the bidirectional threaded rod 12;

[0042] The wiring part 2 includes a distribution seat 21, the bottom of the distribution seat 21 is fixedly connected to the top of the base 11, a receiving plate 22 is arranged on the top of the distribution seat 21, an inner slider 23 is slidably connected to the inside of the receiving plate 22, a screw 24 is threadedly connected to the inside of the inner slider 23, and a wrapping piece 25 detachably mounted on the bottom end of the screw 24 is used for fast cross tightening between wires;

[0043] The clamping part 3 is provided with two clamping parts 3 and symmetrically distributed with the wrapping part 25 as the center. The clamping part 3 includes a fixed mold 31. The outer side of the fixed mold 31 is fixedly connected to the outer side of the base 11, and a movable mold 32 is slidably connected to the top of the fixed mold 31. The fixed mold 31 and the movable mold 32 wrap and clamp the outer side of the wire in a circular manner to prevent the wires from sliding relative to each other when the wires are subsequently cross-tightened, resulting in loosening of the joints between the wires. The adjusting part 33 is rotatably installed on the outer side of the fixed mold 31, and the outer side of the adjusting part 33 is fixedly connected to the inner center of the driving gear 13.

[0044] The outer end of the bidirectional threaded rod 12 is fixedly connected to a servo motor 14, the bottom of the servo motor 14 is fixedly connected to the outer side of the base 11 through a connecting plate, the outer side of the movable mold 32 is fixedly connected to an electromagnetic push rod 34, the bottom of the electromagnetic push rod 34 is fixedly connected to the top of the base 11, and the base 11 is slidably connected to the bottom of the movable mold 32 through a slide rail 35 arranged on the top thereof.

[0045] The fixed mold 31 and the movable mold 32 form a through hole opening upward, and the movable mold 32 is adapted to the outer side of the fixed mold 31 by a limiting rod 36 arranged on its outer side. When placed, the wire with the stripped insulation layer is located outside the movable mold 32 and the fixed mold 31, and extends to one side above the other group of clamping parts 3. Since the other group of clamping parts 3 is not started and is blocked by the limiting rod 36, the wire with the stripped insulation layer is prevented from falling into the other group of clamping parts 3. A blocking rod 37 is fixedly connected to the side of the movable mold 32 away from the limiting rod 36. Several groups of elastic bags 38 are fixedly connected to the inner walls of the fixed mold 31 and the movable mold 32. The elastic bags 38 are compressed to buffer and protect the wires. At the same time, the elastic bags 38 are compressed to undergo elastic deformation, and the contact area between the elastic bags and the wires is increased, thereby increasing the friction on the outer side of the wires.

[0046] The adjusting member 33 includes a driving rod 331, which is connected to the top of the base 11 by being sleeved on a fixed seat 332 on its outer side. The end of the driving rod 331 away from the fixed mold 31 is fixedly connected to the inner center of the driving gear 13, and the other end of the driving rod 331 is rotatably connected to the inside of the fixed mold 31. A U-shaped rod 333 is fixedly connected to the outer side of the driving rod 331, and the outer end of the U-shaped rod 333 is rotatably connected to the inside of the fixed mold 31. Since the two groups of U-shaped rods 333 are performed synchronously, the bending time is saved, the bending accuracy is ensured to be synchronized and consistent, and the stability of the subsequent cross-tightening of the joint parts is improved. In the process of the U-shaped rod 333 driving the wire to bend upward, the limit rod 36 has a limiting and clamping effect on the wire to avoid the wire bending angle being too large, which is not conducive to the subsequent grasping of the wiring part 2. In conjunction with the smooth tube 334 on the U-shaped rod 333, during the bending process of the wire, the outer side of the wire and the outer side of the smooth tube 334 slide relative to each other, and the smooth tube 334 rotates on the U-shaped rod 333 under the action of friction, which facilitates the rapid bending of the wire and reduces the friction force of the smooth tube 334 on the wire, protecting the insulating layer on the outside of the wire, and the bent wire is fixedly engaged between the smooth tube 334 and the limiting rod 36 to prevent the wire from being unstable and falling over.

[0047] A smooth tube 334 is sleeved on the outside of the U-shaped rod 333. The material of the smooth tube 334 is stainless steel. The outside of the U-shaped rod 333 is matched with the outside of the shielding rod 37. When the U-shaped rod 333 is moved upward around the inside of the fixed mold 31, it limits the U-shaped rod 333 to prevent the U-shaped rod 333 from rotating too much and causing the wires to shift, which is not conducive to the subsequent grabbing of the wiring part 2.

[0048] The receiving plate 22 includes a straight plate and a circular plate. After the open circular plate 251 and the friction rod 253 have completed cross-tightening of the two groups of exposed wires, the top ends of the two groups of exposed wires are squeezed by the circular plate, and the open circular plate 251 and the friction rod 253 rotate clockwise so that the scattered wire heads are screwed together again, eliminating the trouble of subsequent manual repairs. A through hole groove 26 is opened inside the receiving plate 22, and the outer side of the inner slider 23 is slidably connected to the inner wall of the through hole groove 26. The top of the inner slider 23 is fixedly connected to a driving motor 27 through a supporting frame, and a hollow square tube 28 is fixedly installed on the output shaft of the driving motor 27. The bottom end of the hollow square tube 28 is located directly above the inner slider 23. A push rod 29 is arranged on the outer side of the straight plate, and one end of the push rod 29 passes through the straight plate and is connected to the outer side of the inner slider 23.

[0049] The top end of the screw rod 24 passes through the inner slider 23 and extends to the inside of the hollow square tube 28. The screw rod 24 is adapted to the inner wall of the hollow square tube 28 through the block 20 arranged at its top end. The side of the anti-slip plate 255 close to the middle fixing plate 252 is hidden in the special-shaped groove 256 to prevent the exposed wires from being stuck between the anti-slip plate 255 and the middle fixing plate 252, so that the two groups of exposed wires can be stably cross-tightened.

[0050] The wrapping member 25 includes an opening circular plate 251 and a middle fixed plate 252. The outer side of the middle fixed plate 252 is fixedly connected to the inner side of the center of the opening circular plate 251. A friction rod 253 is arranged between the adjacent opening circular plates 251 and the middle fixed plates 252. The middle fixed plate 252 is rotatably connected to the anti-slip plate 255 through a reset spring rod 254 arranged inside it. The anti-slip plate 255, the opening circular plate 251 and the middle fixed plate 252 form a closed space after reset. The anti-slip plate 255 is used to limit the position of the wire to prevent the wire from falling off. The opening circular plate 251 is adapted to the outer side of the anti-slip plate 255 by the special-shaped groove 256 arranged inside it. Then the driving motor 27 drives the hollow The square tube 28 rotates clockwise, driving the screw 24 to rotate clockwise through the block 20, and the screw 24 rotates clockwise around the internal thread of the inner slider 23, and the screw 24 synchronously performs clockwise circular rotation and upward movement, driving the open circular plate 251 and the middle fixed plate 252 to synchronously rotate clockwise circular rotation and upward movement, driving the two groups of exposed wires to quickly cross and tighten together upward. Since the open circular plate 251 and the middle fixed plate 252 rotate clockwise at a uniform speed, and cooperate with the fixation of the clamping part 3, the two groups of exposed wires are evenly and tightly wound together. Compared with the traditional manual cross-twisting of the exposed wires together, the drive of the drive motor 27 saves time and effort, and the tightening is uniform. During the uniform clockwise rotation of the open circular plate 251 and the middle fixing plate 252, the two groups of exposed wires are bent due to the centrifugal force and rub against the open circular plate 251 and the friction rod 253. The open circular plate 251 and the friction rod 253 generate torque on the two groups of exposed wires and generate upward traction force, so that the exposed wires that are continuously tightened under the open circular plate 251 and the friction rod 253 are kept tight, thereby preventing the joints between the subsequent wires from loosening.

[0051] A square hole 257 is provided inside the middle fixing plate 252, and a square rod 241 is fixedly connected to the bottom end of the screw rod 24. The outer side of the square rod 241 is tightly fitted with the inner wall of the square hole 257. The square rod 241 is adapted to the inner wall of the square hole 257 through a limiting plate 242 arranged on the outer side thereof. A bolt 258 is threadedly connected to the inner side of the square rod 241. During use of the wire wiring device of the present invention, if the friction rod 253 and the anti-slip plate 255 on one side are damaged or excessively worn, the wrapping piece 25 can be rotated 180° as a whole and reinstalled. At this time, the wrapping piece 25 can still be used continuously, which greatly improves the service life of the wrapping piece 25.

[0052] The friction rod 253 is designed as a variable diameter bent rod, which is made of stainless steel and becomes thinner along the middle fixed plate 252 to the open circular plate 251. When a group of wires slide against the outer side of the friction rod 253, the smooth friction rod 253 reduces the friction of the exposed wires, and the exposed wires are finally moved to the maximum diameter of the variable diameter bent rod under the force, thereby improving the supporting strength of the friction rod 253 for the exposed wires and increasing the service life of the friction rod 253.

[0053] refer to Figure 1-9 In the electrical production process, the wire ends between electrical components are stripped of the insulation layer of the wires, and the exposed wires are twisted together crosswise. The present invention is designed with a clamping part 3, which is provided with two clamping parts 3 and symmetrically distributed with the wrapping piece 25 as the center. The two groups of clamping parts 3 are started successively, and the interval time between the two is controlled by the single-chip control system. After one group of clamping parts 3 is started, the electromagnetic push rod 34 drives the movable mold 32 to slide outward along the slide rail 35, and the movable mold 32 and the fixed mold 31 are separated from each other, so that the wires can be quickly placed between the movable mold 32 and the fixed mold 31. When placed, the wires with the insulation layer stripped are located outside the movable mold 32 and the fixed mold 31, and extend to one side above the other group of clamping parts 3. Since the other group of clamping parts 3 is not started and is blocked by the limit rod 36, the wires with the insulation layer stripped are prevented from falling into the other group of clamping parts 3. The clamping part 3 that is activated first begins to reset, and the electromagnetic push rod 34 pushes the movable mold 32 to wrap and clamp the outer side of the wire in a circumferential manner to prevent the wires from sliding relative to each other when the wires are subsequently cross-tightened, causing the joints between the wires to loosen. Then another set of clamping parts 3 clamps the wires of another electrical component.

[0054] The single-chip control system turns on the servo motor 14 on the operating body 1, and the output shaft of the servo motor 14 drives the bidirectional threaded rod 12 to rotate. The gear meshing drives the two sets of active gears 13 to rotate synchronously, driving the driving rod 331 on the adjusting member 33 to rotate around the fixed seat 332, driving the U-shaped rod 333 to rotate 90° upward around the inside of the fixed mold 31. During the upward rotation of the U-shaped rod 333, the fixed mold 31 and the movable mold 32 are clamped to make the wire bend upward. Since the two sets of U-shaped rods 333 are synchronous, the bending time is saved, the bending accuracy is ensured to be synchronous and consistent, and the stability of the subsequent cross tightening of the joint parts is improved. During the process of the U-shaped rod 333 driving the wire to bend upward, the limit rod 36 plays a role in limiting and clamping the wire, avoiding excessive bending angles of the wire, which is not conducive to the subsequent grasping of the wiring part 2. In conjunction with the smooth tube 334 on the U-shaped rod 333, during the bending process of the wire, the outer side of the wire and the outer side of the smooth tube 334 slide relative to each other, and the smooth tube 334 rotates on the U-shaped rod 333 under the action of friction, which facilitates the rapid bending of the wire and reduces the friction force of the smooth tube 334 on the wire, protecting the insulating layer on the outside of the wire, and the bent wire is fixedly engaged between the smooth tube 334 and the limiting rod 36 to prevent the wire from being unstable and falling over.

[0055] Then the push rod 29 in the wiring part 2 is started, pushing the inner slider 23 to slide forward along the inner wall of the through hole groove 26, driving the driving motor 27, the screw rod 24 and the wrapping piece 25 to move forward synchronously. The wrapping piece 25 includes an open circular plate 251 and a middle fixed plate 252. The open circular plate 251 and the middle fixed plate 252 form a "mountain" shape. During the upward movement of the wrapping piece 25, the passive mold 32 and the fixed mold 31 are fixed, and the smooth tube 334 and the limit rod 36 clamp the clamped wires and contact the anti-slip plate 255 on the wrapping piece 25. The wires push the anti-slip plate 255 to rotate around the middle fixed plate 252 through the reset spring rod 254 until the two groups of wires slide synchronously into the space surrounded by the open circular plate 251 and the middle fixed plate 252, the anti-slip plate 255 is reset and clamped into the special-shaped groove 256, and the two groups of wires are isolated and separated from each other by the middle fixed plate 252. Subsequently, the driving motor 27 drives the hollow square tube 28 to rotate clockwise, and drives the screw 24 to rotate clockwise through the block 20. The screw 24 rotates clockwise around the internal thread of the inner slider 23, and the screw 24 synchronously performs clockwise circular rotation and upward movement, driving the open circular plate 251 and the middle fixed plate 252 to synchronously rotate clockwise circular rotation and upward movement. The reset anti-slip plate 255 and the open circular plate 251 and the middle fixed plate 252 form a closed space. The anti-slip plate 255 is used to limit the position of the wires to prevent the wires from detaching, and drives the two groups of exposed wires to quickly cross and tighten together upward. Since the open circular plate 251 and the middle fixed plate 252 rotate clockwise at a uniform speed, and cooperate with the fixation of the clamping part 3, the two groups of exposed wires are evenly and tightly wound together. Compared with the traditional manual cross-twisting of the exposed wires together, the drive of the driving motor 27 saves time and effort, and the tightening is uniform. During the uniform clockwise rotation of the open circular plate 251 and the middle fixing plate 252, the two groups of exposed wires are bent due to the centrifugal force and rub against the open circular plate 251 and the friction rod 253. The open circular plate 251 and the friction rod 253 generate torque on the two groups of exposed wires and generate upward traction force, so that the exposed wires that are continuously tightened under the open circular plate 251 and the friction rod 253 are kept tight, thereby preventing the joints between the subsequent wires from loosening.

[0056] The receiving plate 22 of the present invention includes a straight plate and a circular plate. After the open circular plate 251 and the friction rod 253 have completed the cross-tightening of the two groups of exposed wires, the tops of the two groups of exposed wires are squeezed by the circular plate, and the open circular plate 251 and the friction rod 253 rotate clockwise to screw the scattered wire heads together again, thus eliminating the trouble of subsequent manual repairs. After the two groups of exposed wires have completed the cross-tightening, the open circular plate 251 and the middle fixing plate 252 automatically detach from the tops of the two groups of exposed wires, making it convenient for the two groups of wires to be quickly taken out, and finally wrapped with insulating tape, which saves time and effort and is simple to operate.

[0057] During the synchronous clockwise rotation of the open circular plate 251 and the middle fixed plate 252, the two groups of exposed wires are in symmetrical positions, one group of wires is forced to fit on the friction rod 253, and the other group of wires is forced to fit at the angle between the middle fixed plate 252 and the friction rod 253. The friction rod 253 is designed as a variable diameter bent rod, and the variable diameter bent rod is made of stainless steel, and the variable diameter bent rod gradually becomes thinner from the middle fixed plate 252 to the open circular plate 251. During the sliding of one group of wires against the outer side of the friction rod 253, the smooth friction rod 253 reduces the friction force of the exposed wires, and the exposed wires are finally forced to move to the maximum diameter of the variable diameter bent rod, thereby improving the supporting strength of the friction rod 253 for the exposed wires and improving the service life of the friction rod 253. Another group of wires are force-fitted at the angle between the middle fixing plate 252 and the friction rod 253. The open circular plate 251 is adapted to the outer side of the anti-slip plate 255 through the special-shaped groove 256 provided inside it. The side of the anti-slip plate 255 close to the middle fixing plate 252 is hidden in the special-shaped groove 256 to prevent the exposed wires from being stuck between the anti-slip plate 255 and the middle fixing plate 252, so that the two groups of exposed wires can be stably cross-tightened.

[0058] A square hole 257 is provided in the middle fixing plate 252, and the square rod 241 below the screw rod 24 is just inserted into the square hole 257, and the square rod 241 is further tightened by the bolt 258, so that the limit plate 242 is closely fitted to the outer end of the square hole 257, so that the bolt 258, the middle fixing plate 252 and the screw rod 24 are combined into a whole. During the use of the wire connection device of the present invention, if the friction rod 253 and the anti-slip plate 255 on one side are damaged or excessively worn, the wrapping member 25 can be rotated 180 degrees as a whole and reinstalled, and the wrapping member 25 can still be used continuously, which greatly improves the service life of the wrapping member 25.
