Description

Technical Field

[0001] This utility model relates to the technical field of conductor core processing devices, and more specifically, to a conductor core twisting device. Background Technology

[0002] In existing wire stripping equipment, after the wire stripping equipment removes the wire insulation to expose the wire core, the wire core needs to be twisted manually. This subsequent twisting of the wire core is time-consuming, labor-intensive, inefficient, and the quality of the twisted wire core cannot be guaranteed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wire core twisting device, which can separate the wire cores exposed outside the conductor after stripping, and the wire cores can be twisted automatically after being separated.

[0004] This utility model provides a wire core twisting device, including a support plate and a wire clamping assembly, a wire core separating assembly, and a wire core twisting assembly connected sequentially from left to right to the lower end of the support plate; the wire clamping assembly is used to clamp the wire, the wire core separating assembly is used to separate the wire cores of the wire located on the wire clamping assembly, and the wire core twisting assembly is used to twist the wire cores of the wire after they have been processed by the wire core separating assembly.

[0005] By adopting the above-described structure, this utility model can separate the wire cores that have been stripped and exposed on the outside of the conductor. After the wire cores are separated, they can be twisted automatically, thereby reducing manpower, improving production efficiency, and ensuring the quality of twisting the wire cores.

[0006] In one possible implementation, the wire clamping assembly includes a first pneumatic gripper; the first pneumatic gripper is vertically fixed to the lower end of the support plate, and the two gripping arms of the first pneumatic gripper are used to clamp the wire; by adopting this wire clamping assembly, when the two gripping arms of the first pneumatic gripper approach each other, the first pneumatic gripper can clamp the wire located behind the wire core, and when the two gripping arms of the first pneumatic gripper move away from each other, the first pneumatic gripper can release the wire.

[0007] In one possible implementation, the wire core separating assembly includes a first movable base, a first cylinder, a second pneumatic gripper, a second cylinder, and a separating pin. The first movable base is movably connected to the lower end of a support plate. The first cylinder is fixed to the lower end of the support plate, and the first movable base is fixed to the piston rod of the first cylinder. The first cylinder drives the first movable base to move left and right relative to the support plate. The second pneumatic gripper is vertically fixed to the lower end of the first movable base. After the two gripping arms of the second pneumatic gripper approach each other, a circumferentially closed clamping gap is formed between the two gripping arms, which is used to allow the wire cores of the conductor to move axially. The second cylinder is fixed to one of the gripping arms of the second pneumatic gripper. The separating pin moves horizontally through the gripping arm of the second pneumatic gripper located on the side where the second cylinder is located. The outer end of the separating pin is fixed to the piston rod of the second cylinder. The second cylinder drives the separating pin to move horizontally so that the inner end of the separating pin is inserted into the gap between the two wire cores of the conductor. By using this wire core separating assembly, the two gripping arms of the second pneumatic gripper first approach each other. At this point, a circumferentially closed clamping gap is formed between the two clamping arms of the second pneumatic gripper, allowing the wire cores of the conductor to move axially. The two wire cores are thus confined within this clamping gap. Next, the second cylinder drives the separating pin to move horizontally, inserting its inner end into the gap between the two wire cores. The two wire cores are then separated by the separating pin. The first cylinder then drives the first moving seat to move from left to right. During this movement, the clamping gap moves relative to the wire cores, and the separating pin separates the two wire cores. The second cylinder then drives the separating pin to move back to its original position, and the two clamping arms of the second pneumatic gripper move away from each other and reset. Finally, the first cylinder drives the first moving seat to move from right to left, causing it to move and reset the second pneumatic gripper. Through this process, the wire core separating assembly can separate the two wire cores of the conductor. Furthermore, the first moving seat is movably connected to the lower end of the support plate via a sliding engagement of a slider and a guide rail.

[0008] In one possible implementation, the inner sides of the two gripping arms of the second pneumatic gripper are respectively provided with a clamping groove and a clamping block, which are arranged horizontally opposite each other. When the two gripping arms of the second pneumatic gripper approach each other, a clamping gap is formed between the clamping groove and the clamping block. With this structure, under the cooperation of the clamping groove and the clamping block, a clamping gap can be easily formed between the clamping groove and the clamping block after the two gripping arms of the second pneumatic gripper approach each other. This clamping gap is used to allow the conductor core to move axially.

[0009] In one possible implementation, the wire core twisting assembly includes a second movable seat, a third cylinder, a rotating shaft, a third pneumatic gripper, and a drive unit. The second movable seat is movably connected to the lower end of a support plate. The third cylinder is fixed to the lower end of the support plate, and the piston rod of the second movable seat and the third cylinder are fixed together. The third cylinder drives the second movable seat to move left and right relative to the support plate. The rotating shaft is rotatably mounted on the lower end of the second movable seat from left to right. The drive unit is connected to the second movable seat and drives the rotating shaft to rotate. The third pneumatic gripper is fixed to the left end of the rotating shaft and clamps the wire cores of the conductor processed by the wire core splitting assembly. By using this wire core twisting assembly, the third cylinder can first drive the second movable seat to move from right to left. At this time, the two gripping arms of the third pneumatic gripper can reach both ends of the conductor. On both sides of the core wire, the two clamping arms of the third pneumatic gripper can clamp the two core wires of the conductor. Then, the drive unit can drive the rotating shaft and the third pneumatic gripper to rotate. At this time, the two core wires of the conductor held by the third pneumatic gripper can be twisted. After the drive unit drives the rotating shaft and the third pneumatic gripper to rotate a certain number of times, the drive unit can stop driving the rotating shaft and the third pneumatic gripper to rotate. Then, the two clamping arms of the third pneumatic gripper can release the two core wires of the conductor. Finally, the third cylinder can drive the second moving seat and the third pneumatic gripper to move from left to right to reset. Through the above process, the core twisting assembly can realize the twisting operation of the two core wires of the conductor. In addition, the second moving seat is connected to the lower end of the support plate by sliding cooperation of the slider and the guide rail.

[0010] In one possible implementation, the lower end of the second movable seat is provided with a shaft hole, and the right side of the rotating shaft passes through the shaft hole and is rotatably connected to the second movable seat through two bearings that are spaced apart to the left and right. With this structure, the right side of the rotating shaft can be reliably rotatably connected to the second movable seat under the action of the two bearings.

[0011] In one possible implementation, an air guide channel is provided inside the rotating shaft. A first air guide connector communicating with the air guide channel is fixed on the left side wall of the rotating shaft. The second air guide connector of the third pneumatic gripper is connected to the first air guide connector through a connecting pipe. A rotary connector communicating with the air guide channel is coaxially connected to the right end of the rotating shaft. The rotary connector is connected to an air source through an air pipe. With this structure, when the rotating shaft is rotating, the air pipe used to connect the rotary connector and the air source can be prevented from getting tangled. In addition, under the action of the air guide channel, the first air guide connector and the second air guide connector, the air source can reliably control the movement of the third pneumatic gripper.

[0012] In one possible implementation, the drive unit includes a servo motor, a driving pulley, a driven pulley, and a transmission belt. The servo motor is fixed on the second movable seat, the driving pulley is coaxially sleeved and fixed on the output shaft of the servo motor, and the driven pulley is coaxially sleeved and fixed on the outside of the right end of the rotating shaft. The driven pulley is connected to the driving pulley via the transmission belt, and the servo motor is electrically connected to the controller. With this structure, when the servo motor drives the driving pulley to rotate, the servo motor can reliably drive the rotation of the rotating shaft and the third pneumatic gripper under the combined action of the transmission belt and the driven pulley.

[0013] In one possible implementation, the drive unit further includes a proximity sensor and a trigger plate; the proximity sensor is fixed on the second movable seat, and the trigger plate is fixed on the outer wall of the rotating shaft; when the rotating shaft drives the trigger plate to rotate, the trigger plate is used to intermittently trigger the proximity sensor, and the proximity sensor is electrically connected to the controller; with the above structure, the trigger plate can trigger the proximity sensor once for each rotation of the rotating shaft and the third pneumatic gripper by the servo motor, and the number of times the proximity sensor is triggered (the number of rotations of the rotating shaft and the third pneumatic gripper) can be recorded in the controller. When the number of rotations of the rotating shaft and the third pneumatic gripper reaches the set number of rotations, the controller will control the servo motor to stop rotating, thereby making it easy to control the number of twists of the two wire cores of the wire by the third pneumatic gripper.

[0014] In one possible implementation, a plurality of guide rods are fixed on one arm of the third pneumatic gripper, spaced apart along the extension direction of the conductor core. The other arm of the third pneumatic gripper has guide holes vertically corresponding to each of the guide rods, with each guide rod movably passing through the corresponding guide hole. Two symmetrical guide blocks are fixed on one arm of the third pneumatic gripper, located on either side of the guide rods and fitted with a clearance between them. Each guide block has a guide ramp on its inner wall. The third pneumatic gripper also has a guide ramp on one arm corresponding to the guide block. A vertically corresponding clearance hole is provided, each clearance hole being used for the vertical insertion of one of the guide blocks. With the third pneumatic gripper using this structure, the movement of the two gripping arms of the third pneumatic gripper can be guided by the cooperation of the guide rod and the guide hole. In addition, under the action of each guide block and the guide slope, the two cores of the conductor can enter the gap between the guide block and the guide rod on the corresponding side under the guidance of one of the guide slopes. And due to the clearance effect of the clearance hole, the clamping of the two cores of the conductor can be reliably achieved after the two gripping arms of the third pneumatic gripper come close to each other.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See Figure 1-5As shown in the figure, this application discloses a wire core twisting device, including a support plate 1 and a wire clamping assembly 2, a wire core separating assembly 3, and a wire core twisting assembly 4 connected sequentially from left to right to the lower end of the support plate 1; the wire clamping assembly 2 is used to clamp the wire, the wire core separating assembly 3 is used to separate the wire cores of the wire located on the wire clamping assembly 2, and the wire core twisting assembly 4 is used to twist the wire cores of the wire after they have been processed by the wire core separating assembly 3.

[0025] In operation, the present invention first clamps the wires located behind the wire cores, then separates the two wire cores of the wires, and then twists the two wire cores of the wires after they have been processed by the wire core separating component.

[0026] See you again Figure 1 As shown, the wire clamping assembly 2 includes a first pneumatic gripper 21; the first pneumatic gripper 21 is vertically fixed on the lower end of the support plate 1, and the two gripping arms of the first pneumatic gripper 21 are used to clamp the wire; by adopting this wire clamping assembly, when the two gripping arms of the first pneumatic gripper are close to each other, the first pneumatic gripper can clamp the wire located behind the wire core, and when the two gripping arms of the first pneumatic gripper are far apart, the first pneumatic gripper can release the wire.

[0027] See you again Figure 1-3As shown, the wire core separating assembly 3 includes a first movable base 31, a first cylinder 32, a second pneumatic gripper 33, a second cylinder 34, and a separating pin 35. The first movable base 31 is movably connected to the lower end of the support plate 1. The first cylinder 32 is fixed to the lower end of the support plate 1, and the piston rod of the first movable base 31 and the first cylinder 32 are fixed. The first cylinder 32 is used to drive the first movable base 31 to move left and right relative to the support plate 1. The second pneumatic gripper 33 is vertically fixed to the lower end of the first movable base 31, and the two gripping arms of the second pneumatic gripper 33 are close to each other. Subsequently, a circumferentially closed clamping gap is formed between the two clamping arms of the second pneumatic gripper 33, providing a clamping gap for the axial movement of the conductor core; the second cylinder 34 is fixed on one of the clamping arms of the second pneumatic gripper 33, and the wire separating needle 35 is horizontally movably inserted into the clamping arm of the second pneumatic gripper 33 located on the side of the second cylinder 34. The outer end of the wire separating needle 35 is fixed to the piston rod of the second cylinder 34, and the second cylinder 34 is used to drive the wire separating needle 35 to move horizontally so that the inner end of the wire separating needle 35 is inserted into the gap between the two conductor cores; by using this conductor core... After the wire separating assembly is completed, the two arms of the second pneumatic gripper first approach each other. At this time, a circumferentially closed clamping gap is formed between the two arms of the second pneumatic gripper, which is used to allow the axial movement of the wire cores. That is, the two wire cores of the wire can be confined in the clamping gap. Then, the second cylinder drives the wire separating pin to move horizontally so that the inner end of the wire separating pin is inserted into the gap between the two wire cores of the wire. At this time, the two wire cores of the wire are separated by the wire separating pin. Then, the first cylinder drives the first moving seat to move from left to right. During the process of the first moving seat moving from left to right, the clamping... The gap allows the wire cores to move from left to right relative to the conductor cores, and the separating pin can separate the two wire cores of the conductor. Then, the second cylinder drives the separating pin to move and reset, and the two clamping arms of the second pneumatic gripper move away from each other and reset. Finally, the first cylinder drives the first moving seat to move from right to left so that the first moving seat drives the second pneumatic gripper to move and reset. Through the above process, the wire core separating assembly can separate the two wire cores of the conductor. In addition, the first moving seat is connected to the lower end of the support plate by sliding cooperation of the slider and the guide rail.

[0028] See you again Figure 3 As shown, the inner sides of the two clamping arms of the second pneumatic gripper 33 are respectively provided with a clamping groove 331 and a clamping block 332, which are arranged horizontally opposite each other. When the two clamping arms of the second pneumatic gripper 33 approach each other, a clamping gap is formed between the clamping groove 331 and the clamping block 332. With this structure, under the cooperation of the clamping groove and the clamping block, a clamping gap can be easily formed between the clamping groove and the clamping block after the two clamping arms of the second pneumatic gripper approach each other. This clamping gap is used to allow the conductor core to move axially.

[0029] See you again Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the wire core twisting assembly 4 includes a second movable seat 41, a third cylinder 42, a rotating shaft 43, a third pneumatic gripper 44, and a drive unit 45. The second movable seat 41 is movably connected to the lower end of the support plate 1, and the third cylinder 42 is fixed to the lower end of the support plate 1. The piston rods of the second movable seat 41 and the third cylinder 42 are fixed, and the third cylinder 42 is used to drive the second movable seat 41 to move left and right relative to the support plate 1. The rotating shaft 43 is rotatably mounted on the lower end of the second movable seat 41 from left to right. The drive unit 45 is connected to the second movable seat 41 and is used to drive the rotating shaft 43 to rotate. The third pneumatic gripper 44 is fixed to the left end of the rotating shaft 43 and clamps the wire cores of the conductor processed by the wire core splitting assembly 3. By using this wire core twisting assembly, the third cylinder can first drive the second movable seat to move from right to left. At this time, the third cylinder... The two gripping arms of the movable jaw can reach both sides of the two wire cores of the conductor. Then, the two gripping arms of the third pneumatic jaw can clamp the two wire cores of the conductor. Then, the drive unit can drive the rotating shaft and the third pneumatic jaw to rotate. At this time, the two wire cores of the conductor held by the third pneumatic jaw can be twisted. After the drive unit drives the rotating shaft and the third pneumatic jaw to rotate a certain number of times, the drive unit can stop driving the rotating shaft and the third pneumatic jaw to rotate. Then, the two gripping arms of the third pneumatic jaw can release the two wire cores of the conductor. Finally, the third cylinder can drive the second moving seat and the third pneumatic jaw to move from left to right to reset. Through the above process, the wire core twisting assembly can realize the twisting operation of the two wire cores of the conductor. In addition, the second moving seat is connected to the lower end of the support plate by sliding cooperation of the slider and the guide rail.

[0030] See you again Figure 5 As shown, the lower end of the second movable seat 41 is provided with a shaft hole 411, and the right side of the rotating shaft 43 passes through the shaft hole 411 and is rotatably connected to the second movable seat 41 through two bearings 46 distributed at left and right intervals.

A first air guide connector 432 communicating with the air guide channel 431 is fixed on the left side wall of the rotating shaft 43. The second air guide connector 441 of the third pneumatic gripper 44 is connected to the first air guide connector 432 through a connecting pipe. The right end of the rotating shaft 43 is coaxially connected to a rotary connector 433 communicating with the air guide channel 431. The rotary connector 433 is connected to the air source through an air pipe. With this structure, when the rotating shaft is rotating, the air pipe used to connect the rotary connector and the air source can be prevented from getting tangled. In addition, under the action of the air guide channel, the first air guide connector and the second air guide connector, the air source can reliably control the movement of the third pneumatic gripper.

[0032] See you again Figure 1 , Figure 2 and Figure 5 As shown, the drive unit 45 includes a servo motor 451, a drive pulley 452, a driven pulley 453, and a transmission belt 454. The servo motor 451 is fixed on the second movable seat 41. The drive pulley 452 is coaxially sleeved and fixed on the output shaft of the servo motor 451. The driven pulley 453 is coaxially sleeved and fixed on the outside of the right end of the rotating shaft 43. The driven pulley 453 is connected to the drive pulley 452 through the transmission belt 454. The servo motor 451 is electrically connected to the controller. With this structure, when the servo motor drives the drive pulley to rotate, the servo motor can reliably drive the rotation of the rotating shaft and the third pneumatic gripper under the combined action of the transmission belt and the driven pulley.

[0033] See you again Figure 1 , Figure 2 and Figure 5 As shown, the drive unit 45 also includes a proximity sensor 455 and a trigger plate 456; the proximity sensor 455 is fixed on the second movable seat 41, and the trigger plate 456 is fixed on the outer wall of the rotating shaft 43; when the rotating shaft 43 drives the trigger plate 456 to rotate, the trigger plate 456 is used to intermittently trigger the proximity sensor 455, and the proximity sensor 455 is electrically connected to the controller; by adopting the above structure, the trigger plate can trigger the proximity sensor once for each rotation of the rotating shaft and the third pneumatic gripper by the servo motor, and the number of times the proximity sensor is triggered (the number of rotations of the rotating shaft and the third pneumatic gripper) can be recorded in the controller. When the number of rotations of the rotating shaft and the third pneumatic gripper reaches the set number of rotations, the controller will control the servo motor to stop rotating, thereby making it easy to control the number of twists of the two wire cores of the wire by the third pneumatic gripper.

[0034] See you again Figure 4As shown, one arm of the third pneumatic gripper 44 has several guide rods 442 fixed at intervals along the extension direction of the conductor core. The other arm of the third pneumatic gripper 44 has guide holes 443 vertically corresponding to the guide rods 442, with each guide rod 442 movably passing through the corresponding guide hole 443. Two symmetrical guide blocks 444 are fixed to one arm of the third pneumatic gripper 44. The two guide blocks 444 are located on both sides of the guide rods 442 and are in clearance fit with them. Each guide block 444 has a guide slope 445 on its inner wall. One arm of the third pneumatic gripper 44... The arm is provided with clearance holes 446 that are vertically corresponding to the guide blocks 444. Each clearance hole 446 is used for vertical insertion of one of the guide blocks 444. With the third pneumatic gripper of this structure, the movement of the two gripping arms of the third pneumatic gripper can be guided by the cooperation of the guide rod and the guide hole. In addition, under the action of each guide block and the guide slope, the two cores of the conductor can enter the gap between the guide block and the guide rod on the corresponding side under the guidance of one of the guide slopes. Due to the clearance effect of the clearance holes, the two gripping arms of the third pneumatic gripper can reliably clamp the two cores of the conductor after they come close to each other.
