Description

Technical Field

[0001] The invention relates to the technical field of thermocouple compensation wires, and more specifically, to a thermocouple compensation wire connection device and a connection method thereof. Background Art

[0002] Thermocouple compensation wire is a special wire used to connect thermocouples and measuring devices. It can compensate for temperature measurement errors caused by changes in ambient temperature within a certain temperature range, ensure the accuracy of temperature measurement, and improve the physical and mechanical properties of the temperature measurement circuit while reducing measurement costs. When in use, the compensation wire needs to be connected to the terminal at the end to extend the cold end of the thermocouple from a place with higher temperature and greater fluctuations to a place with lower temperature and relative stability to ensure the accuracy and stability of temperature measurement.

[0003] The existing device transports the terminals through a vibrating conveyor table, and the front-end terminals are transported to the pressing position for standby use. At the same time, the staff puts a heat shrink tubing on the compensating wire, and then heats the heat shrink tubing so that the heat shrink tubing covers the stripped position of the compensating wire. After that, the staff or the clamping mechanism inserts the stripped end of the compensating wire into the terminal, and then the terminal is squeezed and pressed with the compensating wire.

[0004] However, some thermocouple compensation wires have at least two core wires inside, and the existing device can only crimp terminals for compensation wires with a single wire inside, and only one at a time. If it is a compensation wire with two core wires inside, it still needs to be crimped separately, which greatly reduces work efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a thermocouple compensation wire connection device and a connection method thereof.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a thermocouple compensation wire connection device, comprising a workbench and a main body component, a top material component, a conveying component, a sorting component and a combing component installed on the top of the workbench, the combing component is located near the top material component, and a heat shrink sleeve is arranged on the top of the sorting component.

[0007] The main body component includes a pressure plate arranged above the lifting component, a vibration plate conveying mechanism is installed on the top of the workbench, the lifting component includes a support block and a lifting cylinder installed on the top of the support block, and a track is opened on the top of the support block.

[0008] The combing assembly includes an electric guide rail and two clamping plates slidably connected to the bottom of the electric guide rail. A combing cylinder is hinged in the middle of the bottom surface of the electric guide rail. The piston rod of the combing cylinder is connected to a fixed plate. A roller rotates inside the fixed plate. An L-shaped strip slides on the side wall of the fixed plate.

[0009] The present invention is further configured as follows: the main body component also includes a support block installed on the top of the workbench and a driving cylinder installed on the top of the bracket, the piston rod of the driving cylinder is vertically arranged downward and connected to a slide seat, the slide seat is slidably connected to the side wall of the bracket, the pressure plate is vertically installed on the bottom of the slide seat, and the discharge end of the vibration plate conveying mechanism is connected to the track.

[0010] The present invention is further configured as follows: the combing assembly also includes two lifting cylinders vertically installed on the top of the workbench, the piston rods of the two lifting cylinders are connected to the bottom of the electric guide rail, a slide groove is opened on the side wall of the fixed plate, a spring is arranged inside the slide groove, one end of the L-shaped strip is slidably connected to the inside of the slide groove, the two ends of the spring are respectively connected to the inner wall of the slide groove and the L-shaped strip, and the bottom end extension length of the L-shaped strip is greater than the extension length of the roller.

[0011] By adopting the above technical scheme, when the compensation wire moves to the inside of the track, the two clamping plates approach each other to clamp and position the compensation wire, and then the combing cylinder pushes the fixed plate, the L-shaped pressure strip and the roller downward, and the L-shaped pressure strip first fits the heat shrink sleeve of the compensation wire and flattens the two core wires inside the compensation wire to make them flat, and then the combing cylinder continues to extend, and the L-shaped pressure strip is squeezed against the spring by the reaction force, and at the same time, the L-shaped pressure strip slides upward inside the slide groove, and at this time the roller continues to move downward to fit the heat shrink sleeve of the compensation wire, and the roller fits between the two flat core wires, and then the combing cylinder continues to extend, and the roller rolls between the two core wires, and the two core wires are squeezed and separated inside the track. In this state, the combing of the two core wires can be completed, that is, two terminals can be connected at the same time, which greatly improves the connection efficiency.

[0012] The present invention is further configured as follows: the conveying component is arranged through the sorting component, the conveying component includes a fixed frame installed on the top of the workbench and a conveyor belt mechanism installed inside the fixed frame, a plurality of bases are installed equidistantly on the outer wall of the conveyor belt mechanism, an electric wheel group and two groups of clamps are installed inside each of the bases, and the electric wheel group and the two groups of clamps are arranged in an array.

[0013] The present invention is further configured as follows: the sorting component includes two support frames installed on the top of the workbench, the two support frames are respectively arranged on both sides of the fixed frame, and adjusting cylinders are vertically installed on the side walls of the two support frames, and the piston rod of each adjusting cylinder is connected to an L-shaped plate, and a connecting rod is horizontally connected between the two L-shaped plates, and the outer side wall of the connecting rod is slidably connected to a movable plate, and a swing mechanism is installed on the side wall of the fixed frame and close to the side of the top material assembly, and the swing mechanism is located below the movable plate.

[0014] The present invention is further configured as follows: a tidying cylinder is horizontally installed on the side wall of one of the L-shaped plates away from the top material assembly, the piston rod of the tidying cylinder passes through the corresponding L-shaped plate and is connected to the movable plate, a plurality of auxiliary wheels are rotatably connected to the side wall of the movable plate, a swivel is rotatably connected between the plurality of auxiliary wheels, a second clamping cylinder is vertically installed downward on the side wall of the swivel, both output ends of the second clamping cylinder are connected to an arc plate, and the arc plate is located at the center of the swivel.

[0015] The present invention is further configured as follows: a driving motor is installed on the side wall of the L-shaped plate corresponding to the sorting cylinder, the output end of the driving motor is connected to a square rod, the end of the square rod away from the driving motor is rotatably connected to the side wall of another L-shaped plate, and the square rod passes through the center of one of the auxiliary wheels and is connected to each other, wherein the outer side walls of the three auxiliary wheels are transmission-connected with a transmission belt, and the outer side wall of the transmission belt is in contact with the outer side wall of the swivel.

[0016] The present invention is further configured as follows: a micro-cylinder is horizontally installed on the top of the side wall of the movable plate, the piston rod of the micro-cylinder is connected to an auxiliary plate, the auxiliary plate is slidably connected to the outer side wall of the connecting rod, a third clamping cylinder is vertically installed downward on the side of the auxiliary plate away from the movable plate, both output ends of the third clamping cylinder are connected to auxiliary clamping claws, a first clamping cylinder is vertically installed downward on the side of the movable plate away from the auxiliary plate, both output ends of the first clamping cylinder are installed with first clamping claws, and openings are provided at the bottoms of the auxiliary plate and the movable plate.

[0017] The present invention is further configured as follows: the swing mechanism includes a connecting block installed on the side wall of the fixed frame and close to one side of the top material assembly, the side wall of the connecting block is installed with a swing motor, the output end of the swing motor is connected to the swing frame, and the side wall of the swing frame is installed with an electric clamp.

[0018] By adopting the above technical solution, the auxiliary plate moves up and down synchronously when the movable plate moves up and down. This adjustment can make the horizontal compensation wire pass through the opening to reach the center position of the auxiliary plate and the movable plate. Then the second clamping cylinder drives the two arc plates to clamp the compensation wire. The arc plate is located at the position of the braided shielding layer of the compensation wire. Then, by moving the movable plate, the arc plate can be moved on the braided shielding layer, thereby achieving the effect of arranging the braided shielding layer and avoiding the situation where the staff manually draws the wire and scratches their hands.

[0019] An inclined strip block is arranged inside the arc plate. When the arc plate clamps the compensating wire, the driving motor drives the square rod to rotate, and the square rod drives one of the auxiliary wheels to rotate. The auxiliary wheel drives the transmission belt by friction force, and the transmission belt drives the swivel to rotate by friction force. When the swivel rotates, the second clamping cylinder and the two arc plates are displaced in a circular manner. The arc plate rotates while straightening the wire, and the strip block rotates and squeezes the braided shielding layer to reduce the situation where the shielding layer is damaged due to excessive pulling force caused by direct straightening. The first clamping jaw and the auxiliary clamping jaw are both arranged in an L shape, and the two first clamping jaws and the two auxiliary clamping jaws are respectively staggered, that is, the compensating wire is clamped when it is in a fully close state, and the compensating wire can be supported when it is not in a fully close state. This arrangement can use the clamping or supporting functions of the first clamping jaw and the auxiliary clamping jaw to pull and move the compensating wire or assist in limiting, and finally achieve the purpose of automatically installing the heat shrink sleeve.

[0020] A thermocouple compensation wire connection method, using a thermocouple compensation wire connection device as described above, comprises the following steps: S1. Place the terminals inside the vibration plate conveying mechanism, and convey two of the terminals to the inside of the track through the vibration plate conveying mechanism.

[0021] S2. At the same time, the robot places the peeled compensation wire on the conveying component, and then the conveying component conveys the compensation wire to the direction of the sorting component.

[0022] S3. Then the conveying component conveys the stripped end of the compensation wire toward the direction close to the vibration disk conveying mechanism, causing the compensation wire to be in a drooping state. The sorting component lifts the compensation wire and sorts the braided shielding layer. After sorting, the conveying component retracts the compensation wire and conveys it to the position corresponding to the lifting component and the combing component. The electric wheel group releases the compensation wire again, so that the compensation wire is sent to the inside of the track and under the combing component.

[0023] S4. Then the electric guide rail runs and drives the two clamps to approach each other to clamp the compensation wire. The combing cylinder pushes the fixed plate, L-shaped pressure strip and roller downward. The L-shaped pressure strip and roller are fitted with the heat shrink tubing of the compensation wire in turn. The L-shaped pressure strip flattens the two core wires inside the compensation wire to make them flat. The roller fits between the two flat core wires. Then the combing cylinder continues to extend, and the roller rolls between the two core wires. The two core wires are squeezed and separated inside the track. Then the pushing cylinder pushes the terminals at both ends along the extension direction of the track. The two terminals are respectively mounted on the outside of the two core wires. Then the pushing cylinder is retracted to wait for the next pushing. The terminal is pressed on the end of the core wire by pressing the pressure plate down to complete the connection.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: (1) By setting a clamp, L-shaped pressure strip and roller, when the compensation wire moves into the track, the clamp clamps the positioning wire, and then the combing cylinder pushes the fixed plate, L-shaped pressure strip and roller downward. The L-shaped pressure strip first fits the heat shrink tubing to flatten the core wire, and the roller continues to move downward to fit between the two core wires. As the cylinder further extends, the roller rolls between the core wires to separate the core wires. In this state, two terminals can be connected at one time, significantly improving the connection efficiency.

[0025] (2) By setting a movable plate and an arc plate, the auxiliary plate moves up and down synchronously when the movable plate moves up and down. This adjustment can make the horizontal compensation wire pass through the opening to reach the center position of the auxiliary plate and the movable plate. Then the second clamping cylinder drives the two arc plates to clamp the compensation wire. The arc plate is located at the position of the braided shielding layer of the compensation wire. Then, by moving the movable plate, the arc plate can be moved on the braided shielding layer, thereby achieving the effect of arranging the braided shielding layer and avoiding the situation where the staff manually draws the wire and scratches their hands.

[0026] (3) An inclined strip block is arranged inside the arc plate. When the arc plate clamps the compensation wire, the driving motor drives the square rod to rotate, and the square rod drives one of the auxiliary wheels to rotate. The auxiliary wheel drives the transmission belt by friction, and the transmission belt drives the swivel to rotate by friction. When the swivel rotates, it drives the second clamping cylinder and the two arc plates to move in a circular motion. The arc plate rotates while pulling the wire, and the strip block rotates and squeezes the braided shielding layer, thereby reducing the situation where the shielding layer is damaged due to excessive pulling force caused by direct pulling of the wire.

[0027] (4) By setting the first clamp and the auxiliary clamp, the first clamp and the auxiliary clamp are both set in an L shape, and the two first clamps and the two auxiliary clamps are respectively staggered, that is, the compensating wire is clamped when it is fully close, and the compensating wire can be supported when it is not fully close. This setting can use the clamping or supporting functions of the first clamp and the auxiliary clamp to pull and move the compensating wire or assist in limiting, and finally achieve the purpose of automatically putting on the heat shrink tubing.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0044] See also Figure 1-Figure 13 , the present invention provides the following technical solutions: Embodiment 1, a thermocouple compensation wire connection device, including a workbench 1 and a main component 2 and a top material component 3 installed on the top of the workbench 1, the main component 2 is used to transport and press the terminal, and during the transportation of the terminal, the top material component 3 is used to move the terminal to the press-fit position to facilitate the press-fit operation of the main component 2. The specific structure of the main component 2 is as follows: See also Figure 1 and Figure 2 The main body component 2 includes a pressing plate 24 arranged above the ejecting component 3. The main body component 2 also includes a supporting block 31 installed on the top of the workbench 1 and a driving cylinder 23 installed on the top of the bracket 21. The piston rod of the driving cylinder 23 is vertically arranged downward and connected to a slide 22. The slide 22 is slidably connected to the side wall of the bracket 21. The pressing plate 24 is vertically installed at the bottom of the slide 22. The driving cylinder 23 is used to push the slide 22 to slide on the side wall of the bracket 21, thereby pushing the pressing plate 24 to move up and down. The pressing plate 24 is suitable for squeezing the terminal.

[0045] See also Figure 1A vibration plate conveying mechanism 25 is installed on the top of the workbench 1 , and the vibration plate conveying mechanism 25 is used to spirally arrange the terminals and convey them in the direction of the pressing plate 24 .

[0046] See also Figure 1-Figure 3 The specific structure of the top material component 3 is as follows: The ejection assembly 3 includes a support block 31 and a ejection cylinder 32 installed on the top of the support block 31. A track 33 is opened on the top of the support block 31. The discharge end of the vibration disk conveying mechanism 25 is connected to the track 33. The width of the two ends of the track 33 is greater than the width in the middle, that is, the vibration disk conveying mechanism 25 conveys the terminal to the inside of the track 33, and then the ejection cylinder 32 is extended and retracted inside the track 33, so that the terminal can be pushed from one end of the track 33 to the other end. That is, after the terminal is pushed into place, the pressing plate 24 is above this terminal, and the terminal can be pressed and installed using the pressing plate 24.

[0047] See also Figure 1 , Figure 6 and Figure 7 A conveying assembly 4 is installed on the top of the workbench 1. The conveying assembly 4 is used to convey the stripped compensation wire to facilitate connection with the terminal. The specific structure of the conveying assembly 4 is as follows: The conveying assembly 4 includes a fixed frame 41 installed on the top of the workbench 1 and a conveyor belt mechanism 42 installed inside the fixed frame 41. A plurality of bases 43 are equidistantly installed on the outer wall of the conveyor belt mechanism 42. The conveyor belt mechanism 42 is used to drive the plurality of bases 43 to synchronously displace and convey, and an electric wheel group 45 and two groups of clamps 44 are installed inside each base 43. The electric wheel group 45 and the two groups of clamps 44 are arranged in an array. The clamp 44 can be a V-shaped spring plate structure, that is, when the compensating wire is clamped by the clamp 44, it is only necessary to insert the compensating wire into the inside of the clamp 44, and the clamp 44 is squeezed and deformed by the compensating wire until the compensating wire is completely inserted into the clamp 44. The clamp 44 clamps the compensating wire using elastic force. The electric wheel group 45 is used to electrically convey the compensating wire, that is, the compensating wire can extend or retract from the corresponding base 43, which is convenient for crimping the terminal of the compensating wire.

[0048] Specifically, the staff manually puts the heat shrink tube into the position where the compensation wire is stripped, and then heats it to shrink it to cover the braided metal layer. Then, the stripped compensation wire is stuffed into the inside of the two clamps 44 and the inside of the electric wheel group 45 by a robot for standby use. After the compensation wire is placed, the base 43, the clamp 44, the electric wheel group 45 and the compensation wire are transported to the position of the track 33 by the conveyor belt mechanism 42. Then, the electric wheel group 45 sends the compensation wire out and drops it into the track 33. Then, the top cylinder 32 extends inside the track 33, and then pushes the terminal into place, that is, the terminal is sleeved onto the end of the compensation wire. At this time, the driving cylinder 23 pushes the slide 22 to slide on the side wall of the bracket 21, and then pushes the pressure plate 24 to move up and down. The pressure plate 24 is suitable for squeezing the terminal, thereby completing the connection operation between the compensation wire and the terminal.

[0049] In the second embodiment, some thermocouple compensation wires have at least two core wires inside, and the existing device can only crimp terminals for compensation wires with a single wire inside, and only one is crimped at a time. If it is a compensation wire with two core wires inside, it still needs to be crimped separately, which greatly reduces the work efficiency.

[0050] To this end, a combing assembly 6 is installed on the top of the workbench 1. The combing assembly 6 is located near the top material assembly 3. The combing assembly 6 is used to comb the compensation wire to separate the two core wires inside the compensation wire to facilitate the connection of the terminal. The specific structure of the combing assembly 6 is as follows: See also Figure 2-Figure 5 The combing component 6 includes an electric guide rail 62 and two clamping plates 63 slidably connected to the bottom of the electric guide rail 62. The electric guide rail 62 can be a stepper motor linear guide screw slide module, which is not specifically limited here. The screw in the electric guide rail 62 is a bidirectional screw. Two slides slide on the linear guide rail, and the two slides slide close to or away from each other. The two clamping plates 63 are connected to the two slides, that is, the two clamping plates 63 can move close to or away from each other under the electric guide rail 62. When the compensation wire is transported and moved through the conveying component 4, the compensation wire moves to the inside of the track 33, and then the two clamping plates 63 approach each other to clamp and position the compensation wire.

[0051] See also Figure 2-Figure 5The middle part of the bottom surface of the electric guide rail 62 is hinged with a combing cylinder 64. When the combing cylinder 64 is in a retracted state, the combing cylinder 64 is in a tilted downward state as a whole, so that the combing cylinder 64 can guide the swing and tilt when it is extended. The piston rod of the combing cylinder 64 is connected to a fixed plate 65, and a roller 69 is rotated inside the fixed plate 65. An L-shaped pressure strip 68 slides on the side wall of the fixed plate 65. The combing assembly 6 also includes two lifting cylinders 61 vertically installed on the top of the workbench 1. The piston rods of the two lifting cylinders 61 are both connected to the bottom of the electric guide rail 62. A slide groove 66 is provided on the side wall of the fixed plate 65. A spring 67 is provided inside the slide groove 66. One end of the L-shaped pressure strip 68 is slidably connected to the inside of the slide groove 66. The two ends of the spring 67 are respectively connected to the inner wall of the slide groove 66 and the L-shaped pressure strip 68. The bottom end of the L-shaped pressure strip 68 extends longer than the extension length of the roller 69.

[0052] Specifically, when the combing cylinder 64 is extended, the combing cylinder 64 pushes the fixed plate 65, the L-shaped pressure strip 68 and the roller 69 downward, and the L-shaped pressure strip 68 first fits with the heat shrink sleeve 7 of the compensation wire and flattens the two core wires inside the compensation wire to make them flat, and then the combing cylinder 64 continues to extend, and the L-shaped pressure strip 68 squeezes the spring 67 under the reaction force, and at the same time, the L-shaped pressure strip 68 slides upward inside the slide groove 66, and at this time, the roller 69 continues to move downward and fits with the heat shrink sleeve 7 of the compensation wire, and the roller 69 fits between the two flat core wires, and then the combing cylinder 64 continues to extend, and the roller 69 rolls between the two core wires, and the two core wires are squeezed and separated inside the track 33. In this state, the combing of the two core wires can be completed, that is, two terminals can be connected at the same time, which greatly improves the connection efficiency.

[0053] Then, the ejection cylinder 32 pushes the two end terminals along the extension direction of the track 33, and the two terminals are respectively sleeved onto the outside of the two core wires, and then the ejection cylinder 32 is retracted to wait for the next ejection.

[0054] Embodiment three: The existing method is to manually apply a heat shrink tube separately and then place it in the pressing position. This method is inefficient and requires workers to manually straighten the wires. The tinned copper wire braided shielding layer is woven from fine metal wires, and the edges may be sharp. After peeling, the tinned copper wire braided shielding layer is messy. During the manual straightening process, if these edges are accidentally touched, it may cause scratches on the hands.

[0055] For this purpose, a finishing component 5 is installed on the top of the workbench 1, and the conveying component 4 is arranged through the finishing component 5. A heat shrink sleeve 7 is arranged on the top of the finishing component 5. The finishing component 5 is suitable for automatically finishing the braided shielding layer of the compensation wire and automatically setting the heat shrink sleeve 7. The specific structure of the finishing component 5 is as follows: See also Figure 1 , Figure 6 , Figure 8-Figure 13 The finishing component 5 includes a swing mechanism 54 installed on the side wall of the fixing frame 41 and close to the side of the top material component 3. When the compensation wire is conveyed by the conveying component 4, the compensation wire is retracted by the electric wheel group 45. When the compensation wire moves to the position of the finishing component 5, the compensation wire is released by the electric wheel group 45. The swing mechanism 54 is used to assist in supporting and clamping the compensation wire, so that the compensation wire can be adjusted to a horizontal state, which is convenient for the finishing component 5 to automatically sort the braided shielding layer of the compensation wire. The specific structure of the swing mechanism 54 is as follows: The swing mechanism 54 includes a connecting block 541 installed on the side wall of the fixed frame 41 and close to the side of the top material component 3, and a swing motor 542 is installed on the side wall of the connecting block 541. The output end of the swing motor 542 is connected to the swing frame 543, and an electric clamp 544 is installed on the side wall of the swing frame 543. The swing motor 542 is used to drive the swing frame 543 to swing, and the swing frame 543 can lift the compensation wire. At the same time, the electric clamp 544 obtains and clamps the compensation wire. The swing frame 543 can pull the compensation wire to a horizontal state during the swinging process, thereby facilitating the subsequent arrangement of the braided shielding layer.

[0056] Specifically, the corresponding electric wheel group 45 conveys the stripped end of the compensation wire toward the direction close to the vibration disk conveying mechanism 25, causing the compensation wire to be in a drooping state. At this time, the swing frame 543 is adjusted to a vertical downward state, and the compensation wire falls onto the surface of the swing frame 543 and the inside of the electric clamp 544 which is in an open state. Then, the electric clamp 544 clamps the end of the compensation wire, and then the swing motor 542 drives the swing frame 543, the electric clamp 544 and the compensation wire to swing, causing the swing frame 543 to swing to a tilted upward state, and the compensation wire is pulled to a horizontal state to wait for the arrangement of the braided shielding layer.

[0057] See also Figure 8-Figure 13The finishing assembly 5 also includes two support frames 51 installed on the top of the workbench 1. The two support frames 51 are respectively arranged on both sides of the fixed frame 41. Adjustment cylinders 52 are vertically installed on the side walls of the two support frames 51. The piston rod of each adjustment cylinder 52 is connected to an L-shaped plate 53. The adjustment cylinder 52 is used to push the corresponding L-shaped plate 53 to move up and down. A connecting rod 56 is horizontally connected between the two L-shaped plates 53. The outer side wall of the connecting rod 56 is slidably connected to a moving plate 57. The swing mechanism 54 is located below the moving plate 57. The L-shaped plate 53 drives the connecting rod 56 and the movable plate 57 to move up and down while moving up and down. A micro cylinder 501 is horizontally installed on the top of the side wall of the movable plate 57. The piston rod of the micro cylinder 501 is connected to an auxiliary plate 504. The auxiliary plate 504 is slidably connected to the outer wall of the connecting rod 56. A third clamping cylinder 5001 is vertically installed downward on the side of the auxiliary plate 504 away from the movable plate 57. The two output ends of the third clamping cylinder 5001 are both connected to auxiliary clamping claws 5002. The side of the movable plate 57 away from the auxiliary plate 504 A first clamping cylinder 502 is installed vertically downward, and first clamping claws 503 are installed at both output ends of the first clamping cylinder 502. The bottoms of the auxiliary plate 504 and the movable plate 57 are both provided with openings. When the movable plate 57 moves up and down, the auxiliary plate 504 moves up and down synchronously. This adjustment can make the horizontal compensation wire pass through the opening to reach the center position of the auxiliary plate 504 and the movable plate 57. At this time, the first clamping cylinder 502 drives the two first clamping claws 503 to approach each other, and the third clamping cylinder 5001 drives the two auxiliary plates 504 and 507 to move up and down. The jaws 5002 are close to each other to clamp the compensation wire. The first jaw 503 and the auxiliary jaw 5002 are both set to be L-shaped, and the two first jaws 503 and the two auxiliary jaws 5002 are staggered respectively, that is, the compensation wire is clamped when they are completely close to each other, and the compensation wire can be supported when they are not completely close to each other. The micro cylinder 501 is used to push the auxiliary plate 504 to move, which not only adjusts the distance between the auxiliary plate 504 and the movable plate 57, but also can adjust the position of the two auxiliary jaws 5002 to clamp the compensation wire.

[0058] See also Figure 8-Figure 13A tidying cylinder 55 is horizontally installed on the side wall of one of the L-shaped plates 53 away from the ejection assembly 3. The piston rod of the tidying cylinder 55 penetrates the corresponding L-shaped plate 53 and is connected to the moving plate 57. The tidying cylinder 55 is used to drive the moving plate 57 to slide and adjust its position on the outer wall of the connecting rod 56. A plurality of auxiliary wheels 505 are rotatably connected to the side wall of the moving plate 57. A swivel 506 is rotatably connected between the plurality of auxiliary wheels 505. A second clamping cylinder 508 is vertically installed downward on the side wall of the swivel 506. Both output ends of the second clamping cylinder 508 are connected to the An arc plate 509 is connected, and the arc plate 509 is located at the center of the swivel 506. A driving motor 58 is installed on the side wall of the L-shaped plate 53 corresponding to the sorting cylinder 55. The output end of the driving motor 58 is connected to a square rod 59. The end of the square rod 59 away from the driving motor 58 is rotatably connected to the side wall of another L-shaped plate 53, and the square rod 59 passes through the center of one of the auxiliary wheels 505 and is connected to each other. The outer walls of the three auxiliary wheels 505 are connected to the transmission belt 507, and the outer wall of the transmission belt 507 is in contact with the outer wall of the swivel 506.

[0059] The second clamping cylinder 508 is used to drive two arc plates 509 to clamp the compensation wire. The arc plates 509 are located at the position of the braided shielding layer of the compensation wire. Then, by moving the movable plate 57, the arc plates 509 can be moved on the braided shielding layer, thereby achieving the effect of arranging the braided shielding layer, avoiding the situation where the staff manually draws the wire and scratches their hands.

[0060] At the same time, the driving motor 58 is used to drive the square rod 59 to rotate, and the square rod 59 drives one of the auxiliary wheels 505 to rotate. The auxiliary wheel 505 uses friction to drive the transmission belt 507 to transmit, and the transmission belt 507 uses friction to drive the swivel 506 to rotate. When rotating, the swivel 506 drives the second clamping cylinder 508 and two arc plates 509 to move in a circle. An inclined strip block is arranged inside the arc plate 509. The arc plate 509 rotates while straightening the wire. The strip block rotates and squeezes the braided shielding layer to reduce the damage of the shielding layer caused by excessive pulling force of direct straightening.

[0061] Specifically, when the compensation wire is at the center position of the auxiliary plate 504 and the movable plate 57, the adjusting cylinder 52 drives the L-shaped plate 53 to move downward, so that the components installed on the two L-shaped plates 53 move downward, and the compensation wire moves to the center position through the movable plate 57, the auxiliary plate 504 and the opening below the rotating ring 506. In this state, the third clamping cylinder 5001 and the first clamping cylinder 502 are operated, and the two auxiliary clamping jaws 5002 and the two first clamping jaws 503 are close to each other to limit the compensation wire without clamping it. At the same time, the second clamping cylinder 508 drives the two arc plates 509 to move closer to each other and the compensation wire. The outer wall of the wire is fitted, and then the arranging cylinder 55 pushes the moving plate 57 to move, and the two auxiliary clamps 5002 and the two first clamps 503 cooperate to support the compensation wire, and the two arc plates 509 move outside the compensation wire. At the same time, the driving motor 58 drives the square rod 59 and one of the auxiliary wheels 505 to rotate, and the auxiliary wheel 505 drives the transmission belt 507 to transmit, so that the transmission belt 507 drives the swivel 506 to rotate, and multiple auxiliary wheels 505 cooperate to support the swivel 506. In this state, the arc plate 509 rotates while moving, so that the external braided shielding layer of the compensation wire is arranged.

[0062] After the arrangement is completed, the electric clamp 544 releases the compensation wire and the swing frame 543 is restored to the vertical downward state. The two arc plates 509 are separated. At the same time, the two auxiliary clamps 5002 clamp the compensation wire. The micro cylinder 501 pushes the auxiliary plate 504, the third clamping cylinder 5001, the auxiliary clamp 5002 and the compensation wire to move forward. The end of the compensation wire is sent into the interior of the heat shrinkable sleeve 7. Then the arrangement cylinder 55 contracts, and the micro cylinder 501 continues to extend. The contraction speed of the arrangement cylinder 55 is the same as the extension speed of the micro cylinder 501. After the moving plate 57 retreats a certain distance, the two auxiliary clamps 5002 release the compensation wire, and the two first clamps 503 clamp the compensation wire. Then the arrangement cylinder 55 The micro cylinder 501 stretches, while the micro cylinder 501 contracts at the same speed, and the compensating wire continues to be transported forward until the end of the compensating wire passes through the interior of the heat shrinkable sleeve 7, and the braided shielding layer enters the interior of the heat shrinkable sleeve 7. The external heating device heats the heat shrinkable sleeve 7, so that the heat shrinkable sleeve 7 shrinks due to the heat and covers the position of the braided shielding layer on the compensating wire. Then the sorting component 5 loosens the compensating wire as a whole and moves it up to reset. The electric wheel group 45 runs to retract the compensating wire for standby use. The conveyor belt mechanism 42 transports the compensating wire to the position corresponding to the top material component 3 and the combing component 6. The electric wheel group 45 releases the compensating wire again, so that the compensating wire is sent to the inside of the track 33 and the bottom of the combing component 6 for terminal connection.

[0065] The more specific steps of S2 are: S21. At the same time, the robot inserts the peeled compensation wire into the inside of the two clamps 44 and the inside of the electric wheel group 45 for standby. After the compensation wire is placed, the conveyor belt mechanism 42 drives the base 43, the clamp 44, the electric wheel group 45 and the compensation wire to the lower position of the sorting component 5 for standby.

[0066] S3, then the conveying component 4 conveys the stripped end of the compensation wire toward the direction close to the vibration disk conveying mechanism 25, causing the compensation wire to be in a drooping state, the sorting component 5 lifts the compensation wire and sorts the braided shielding layer, and after sorting, the conveying component 4 retracts the compensation wire and conveys it to the position corresponding to the top material component 3 and the combing component 6, and the electric wheel group 45 releases the compensation wire again, so that the compensation wire is sent to the inside of the track 33 and under the combing component 6.

[0067] The more specific steps of S3 are: S31, then the corresponding electric wheel group 45 transports the stripped end of the compensation wire toward the direction close to the vibration disk conveying mechanism 25, causing the compensation wire to be in a drooping state. At this time, the swing frame 543 is adjusted to a vertical downward state, and the compensation wire falls onto the surface of the swing frame 543 and the inside of the electric clamp 544 in an open state. Then the electric clamp 544 clamps the end of the compensation wire.

[0068] S32, then the swing motor 542 drives the swing frame 543, the electric clamp 544 and the compensation wire to swing, causing the swing frame 543 to swing to an inclined upward state, and the compensation wire is pulled to a horizontal state, and the adjusting cylinder 52 drives the L-shaped plate 53 to move downward, causing the components installed on the two L-shaped plates 53 to move downward, and the compensation wire moves to the center position through the movable plate 57, the auxiliary plate 504 and the opening under the swivel 506. In this state, the third clamping cylinder 5001 and the first clamping cylinder 502 are in operation, and the two auxiliary clamps 5002 and the two first clamps 503 approach each other to limit the compensation wire but do not clamp it. At the same time, the second clamping cylinder 508 drives the two arc plates 509 to approach each other and fit the outer wall of the compensation wire.

In this state, the arc plate 509 rotates while moving, so that the external braided shielding layer of the compensation wire is arranged.

[0070] S34. After the sorting is completed, the electric clamp 544 releases the compensation wire and restores the swing frame 543 to the vertical downward state. The two arc plates 509 are separated, and at the same time, the two auxiliary clamps 5002 clamp the compensation wire. The micro cylinder 501 pushes the auxiliary plate 504, the third clamping cylinder 5001, the auxiliary clamp 5002 and the compensation wire to move forward, and the end of the compensation wire is sent into the interior of the heat shrinkable sleeve 7. Then the sorting cylinder 55 contracts and the micro cylinder 501 continues to extend, and the contraction speed of the sorting cylinder 55 is the same as the extension speed of the micro cylinder 501. After the moving plate 57 retreats a certain distance, the two auxiliary clamps 5002 release the compensation wire, and the two first clamps 503 clamp the compensation wire. Then the sorting cylinder 55 extends, and the micro cylinder 501 contracts at the same speed, and the compensation wire continues to be transported forward until the end of the compensation wire passes through the inside of the heat shrinkable sleeve 7 and the braided shielding layer enters the inside of the heat shrinkable sleeve 7.

[0071] S35, the external heating device heats the heat shrinkable tube 7, so that the heat shrinkable tube 7 shrinks due to the heat and covers the position of the braided shielding layer on the compensation wire. Then the finishing component 5 loosens the compensation wire as a whole and moves it up to reset. The electric wheel group 45 runs to retract the compensation wire for standby use. The conveyor belt mechanism 42 conveys the compensation wire to the position corresponding to the top material component 3 and the combing component 6. The electric wheel group 45 releases the compensation wire again, so that the compensation wire is sent to the inside of the track 33 and the bottom of the combing component 6.
