Description

Technical Field

[0001] This invention relates to the field of terminal crimping technology, specifically to a crimping device for wiring terminals. Background Technology

[0002] With the continuous development of technology and the rapid progress of society, the electrical industry has also developed rapidly, and the application of electrical equipment is increasing. In electrical equipment, electronic components need to be electrically connected via wires, requiring a large number of wires. Terminal crimping is a process in electrical connections where mechanical pressure is used to tightly bond terminals and wires, forming a reliable electrical connection and mechanical fixation. Terminal crimping is widely used in automobiles, home appliances, industrial control, new energy, and other fields. Its core objectives are to ensure low contact resistance, high mechanical strength, vibration resistance, corrosion resistance, and to avoid safety hazards such as loose connections and overheating. In short, terminal crimping is one of the important steps in the production of connecting wires; therefore, terminal crimping equipment is required.

[0003] Currently, existing terminal crimping equipment crimps terminals so that the crimped shape is aligned with the axial direction of the wire, preventing multi-directional compaction. This can easily lead to loose terminals, and in severe cases, terminals may even fall off, affecting the overall crimping effect. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: A crimping device for terminal blocks, comprising: The machine body, and the cabinet installed on the side of the machine body surface, a protective cover is fixedly installed on the side of the top of the machine body, and a rotating feeding mechanism is installed in the middle of the top of the machine body; A compaction mechanism is used to crimp the terminals at the ends of the wires, and the compaction mechanism is installed in the middle of the inner cavity of the protective cover; The compaction mechanism includes a hydraulic cylinder, which is fixedly installed at the top of the inner cavity of the protective cover. A connecting base tooth is fixedly connected to the telescopic end of the hydraulic cylinder. A U-shaped crimping member is fixedly connected to the bottom end of the connecting base tooth, with the opening of the U-shaped crimping member facing downwards. A square insert is fixedly connected to the bottom end of the U-shaped crimping member. A groove is provided on the side of the top of the inner cavity of the U-shaped crimping member. A rolled edge clamping assembly is installed in the middle of the U-shaped crimping member. By extending the telescopic end of the hydraulic cylinder, a downward pushing force can be applied to the connecting base tooth, allowing the U-shaped crimping member and the rolled edge clamping assembly to move downwards together through the connection of the connecting base tooth. By retracting the telescopic end of the hydraulic cylinder, an upward pulling force can be applied to the connecting base tooth, causing the U-shaped crimping member and the rolled edge clamping assembly to move upwards. This allows for adjustment of the overall height of the U-shaped crimping member and the rolled edge clamping assembly, facilitating the crimping processing of the wiring terminals. The rolled-edge clamping assembly includes a triangular pressure block, a snap-fit ​​washer, and a screw. The triangular pressure block is installed at the top of the U-shaped crimping member's inner cavity. The snap-fit ​​washer is snapped into the middle of the top of the U-shaped crimping member. A through hole is formed in the middle of the surface of the snap-fit ​​washer. The bottom end of the screw passes through the center of the through hole and extends into the interior of the U-shaped crimping member. The bottom end of the screw is threaded onto the top of the triangular pressure block. Pressing clamps are fixedly connected to the sides of the surface of the triangular pressure block. The two corners of the top of the triangular pressure block extend into the interior of the groove, allowing the inner cavity of the U-shaped crimping member to... The rounded concave surface at the corner smoothly transitions to the rounded curved surface of the triangular pressure block. After being squeezed and bent by the rounded concave surface at the corner of the U-shaped crimping member through the opening at the top of the terminal, the opening at the top of the terminal continues to be squeezed and bent. The pressing clamp applies radial pressing force to the top of the terminal, causing the top of the terminal to be concave inward. This means that the wire is subjected to not only axial compression but also radial compression, increasing the contact area between the terminal and the wire. This makes it less likely for the terminal and the wire to fall off, ensuring safety and reliability.

[0005] Preferably, the hydraulic cylinders are installed vertically, and there are two hydraulic cylinders installed symmetrically along the central axis of the U-shaped crimping member. The corner of the top of the inner cavity of the U-shaped crimping member is a concave arc. The extension and retraction end of the hydraulic cylinder drives the U-shaped crimping member to move downward. The two ends of the bottom of the U-shaped crimping member are inclined, so that the opening at the top of the terminal contact the inner surface of the U-shaped crimping member. As the U-shaped crimping member continues to move downward, the opening at the top of the terminal is subjected to an inward squeezing force. Combined with the concave arc at the corner of the top of the inner cavity of the U-shaped crimping member, the opening at the top of the terminal can be squeezed and bent inward, so that the opening at the top of the terminal is easy to crimp onto the wire after bending.

[0006] Preferably, the square insert is installed directly below the U-shaped crimping member, the U-shaped crimping member is installed vertically, there are two square inserts, and the two square inserts are installed symmetrically along the central axis of the U-shaped crimping member.

[0007] Preferably, the pointed end of the triangular pressure block faces downward, and the pressing surfaces on both sides of the triangular pressure block are arc-shaped surfaces. The two corners at the top of the triangular pressure block extend into the interior of the groove. There are four pressing clamps, and the four pressing clamps are evenly distributed on the pressing surface on the outer side of the triangular pressure block.

[0008] Preferably, the screw is installed vertically, and the screw fixes the retaining plate and the triangular pressure block to the U-shaped pressure member. There are two screws, and the two screws are installed symmetrically along the connecting base teeth.

[0009] Preferably, the rotary feeding mechanism includes a driver and a support shaft. The driver is fixedly installed at the top of the machine body cavity. The support shaft is rotatably installed at the middle of the top of the machine body via a bushing. A worktable is fixedly connected to the top of the support shaft. A rectangular limiting groove is provided on the side of the top of the worktable. A rectangular blind hole is provided on the top of the worktable near the rectangular limiting groove, and the rectangular blind hole is located directly below the square insert. An air pump is fixedly installed at the bottom of the worktable. An air passage is provided inside the worktable. When the U-shaped crimping member moves downward, the square insert moves downward along with it. By inserting the bottom end of the square insert into the rectangular blind hole, the U-shaped crimping member is supported and limited by the square insert, thus preventing the U-shaped crimping member from shaking or shifting, which helps to accurately crimp the terminals.

[0010] Preferably, the support shaft is installed vertically and directly above the driver. The bottom end of the support shaft is fixedly installed to the output end of the driver top via a coupling. The rectangular limiting grooves are evenly distributed on the edge of the top of the worktable. By using the upward opening of the terminal block and the terminal block falling into the interior of the rectangular limiting groove, the terminal block can be initially limited. The suction force of the suction pump is used to draw out the air in the air passage. By using the air inlet of the air passage at the bottom of the inner cavity of the rectangular limiting groove, the terminal block in the rectangular limiting groove is sucked in and fixed under the action of negative pressure, so that the terminal block will not be tilted.

[0011] Preferably, the air inlet at the top of the air passage is located at the bottom of the rectangular limiting groove, and the air outlet at the bottom of the air passage is connected to the air inlet of the suction pump. The suction pump is evenly distributed at the bottom of the worktable. When a terminal block is placed in the rectangular limiting groove at the top of the worktable, and the end of the wire is inserted into the terminal block by an external robot, the rotation of the driver output can drive the support shaft to rotate, thereby causing the worktable to rotate as well. Combined with the rectangular limiting grooves being evenly distributed at the top of the worktable, the terminal blocks can be fed in an orderly manner, which can adapt to batch crimping processing.

[0012] Preferably, a terminal feeder is installed on the side of the top of the machine body. The terminal feeder includes a support frame, the bottom of which is fixedly installed to the side of the top of the machine body. A guide trough is fixedly connected to the top of the support frame. A right-angle positioning rod is fixedly connected to the outlet at the bottom of the guide trough. A rectangular limiting groove is located between the right-angle positioning rod and the outlet at the bottom of the guide trough. A camera is fixedly installed on the side of the surface of the guide trough. A controller is fixedly installed at the bottom of the guide trough. A strip-shaped hopper is installed at the inlet at the top of the guide trough. The right-angle positioning... A rubber baffle strip is fixedly connected to the end of the inner side of the rod. The inside of the guide trough and the inside of the strip hopper are filled with terminals. The guide trough is installed at an angle, so the terminals in the rectangular limiting groove slide down in an orderly manner. Since the rectangular limiting groove is located between the right-angle positioning rod and the discharge port at the bottom of the guide trough, the terminals will fall into the rectangular limiting groove. Under the protection of the rubber baffle strip, the terminals will not fall off. As the worktable continues to rotate, the rotational force of the worktable on the terminals is greater than the blocking force of the rubber baffle strip, so the terminals will move and be fed with the rotation of the worktable.

[0013] Preferably, the camera and driver are electrically connected to the controller. The material guide trough is installed at an angle, and the strip hopper is installed vertically to the material guide trough. The rubber baffle is arc-shaped. The camera takes pictures and collects information by rotating the worktable and causing the material guide trough to rotate together. When there are no terminals in the material guide trough, the camera will transmit the collected information to the controller. The controller can then process the signal and control the output of the driver to rotate in the opposite direction. The worktable is driven to rotate in the opposite direction through the support shaft, which facilitates the refilling of the empty material guide trough and prevents the occurrence of empty material.

[0014] This invention provides a crimping device for wiring terminals. It has the following advantages: 1. The crimping equipment for this terminal block utilizes the extension of the hydraulic cylinder's telescopic end to apply a downward pushing force to the connecting base teeth. This allows the U-shaped crimping piece and the rolled edge clamping assembly to move downwards together through the connection of the connecting base teeth. Conversely, the retraction of the hydraulic cylinder's telescopic end applies an upward pulling force to the connecting base teeth, causing the U-shaped crimping piece and the rolled edge clamping assembly to move upwards. This allows for adjustment of the overall height of the U-shaped crimping piece and the rolled edge clamping assembly, facilitating the crimping process of the terminal block.

[0015] 2. The crimping equipment for this terminal block uses the telescopic end of a hydraulic cylinder to move a U-shaped crimping member downwards. The two ends of the bottom of the U-shaped crimping member are inclined, causing the opening at the top of the terminal block to contact the inner surface of the U-shaped crimping member. As the U-shaped crimping member continues to move downwards, the opening at the top of the terminal block is subjected to inward squeezing force. Combined with the arc-shaped concave surface at the corner of the top of the inner cavity of the U-shaped crimping member, the opening at the top of the terminal block can be squeezed and bent inwards, making it easier to crimp onto the wire after bending.

[0016] Third, the crimping device for this terminal block utilizes the two corners of the top of the triangular pressure block extending into the interior of the groove, allowing the arc-shaped concave surface at the corner of the U-shaped crimping member to smoothly transition with the arc-shaped curved surface of the triangular pressure block. After being squeezed and bent by the arc-shaped concave surface at the corner of the U-shaped crimping member through the opening at the top of the terminal block, the opening at the top of the terminal block continues to be squeezed and bent. Furthermore, the pressing clamp applies radial pressing force to the top of the terminal block, causing the top of the terminal block to indent inward. This ensures that the wire is subjected to not only axial compression but also radial compression, increasing the contact area between the terminal block and the wire, making it less likely for the terminal block and the wire to detach, thus ensuring safety and reliability.

[0017] Fourth, the crimping equipment for this terminal block moves the U-shaped crimping piece downwards, causing the square insert to move downwards as well. By inserting the bottom end of the square insert into the rectangular blind hole, the U-shaped crimping piece is supported and limited by the square insert, thus preventing the U-shaped crimping piece from shaking or shifting, which helps to accurately crimp the terminal block.

[0018] 5. The crimping equipment for this terminal block utilizes the upward opening of the terminal block and the terminal block falling into the rectangular limiting groove to initially limit the terminal block. The suction force of the air pump is used to draw out the air inlet of the air passage. Under the action of negative pressure, the terminal block in the rectangular limiting groove is sucked in and fixed, thus preventing the terminal block from tilting.

[0019] VI. The crimping equipment for this terminal block, when a terminal block is placed in the rectangular limiting groove on the top of the workbench, and the end of the wire is inserted into the terminal block by an external robot, the rotation of the output end of the driver can drive the support shaft to rotate, which in turn drives the workbench to rotate. Combined with the rectangular limiting grooves being evenly distributed on the top of the workbench, the terminal blocks can be fed in an orderly manner, which can adapt to batch crimping processing.

[0020] 7. The crimping equipment for this terminal block utilizes the inclined installation of the guide trough, which allows the terminal blocks in the rectangular limiting groove to slide down in an orderly manner. Since the rectangular limiting groove is located between the right-angle positioning rod and the discharge port at the bottom of the guide trough, the terminal blocks will fall into the rectangular limiting groove. Under the obstruction of the rubber baffle strip, the terminal blocks will not detach. As the worktable continues to rotate, the rotational force of the worktable on the terminal blocks is greater than the obstruction force of the rubber baffle strip, so that the terminal blocks will move and be fed along with the rotation of the worktable.

[0021] 8. The crimping equipment for the terminal block uses a camera to capture information. When there is no terminal block in the feed trough, the camera will transmit the captured information to the controller. The controller can then process the signal and control the output of the driver to rotate in the opposite direction. The worktable is driven to rotate in the opposite direction through the support shaft, which facilitates the secondary feeding of the empty feed trough and prevents the occurrence of empty material.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: A crimping device for terminal blocks, comprising: The machine body 1, and the cabinet 2 installed on the side of the surface of the machine body 1, the protective cover 3 is fixedly installed on the side of the top of the machine body 1, and the rotating feeding mechanism 4 is installed in the middle of the top of the machine body 1. The compaction mechanism 5 is used to crimp the terminals at the ends of the wires. The compaction mechanism 5 is installed in the middle of the inner cavity of the protective cover 3. The compaction mechanism 5 includes a hydraulic cylinder 51, which is fixedly installed at the top of the inner cavity of the protective cover 3. A connecting base tooth 52 is fixedly connected to the telescopic end of the hydraulic cylinder 51. A U-shaped pressing component 53 is fixedly connected to the bottom end of the connecting base tooth 52, with the opening of the U-shaped pressing component 53 facing downwards. A square insert 54 is fixedly connected to the bottom end of the U-shaped pressing component 53. A groove 55 is provided on the side of the top of the inner cavity of the U-shaped pressing component 53. A rolled-edge clamping assembly 56 is installed in the middle of the U-shaped pressing component 53. The operator activates the hydraulic cylinder 51 to perform the operation. By extending the telescopic end of the hydraulic cylinder 51, a downward pushing force can be applied to the connecting base tooth 52. Through the connection of the connecting base tooth 52, the U-shaped crimping member 53 and the rolled edge clamping assembly 56 can move downward together. By retracting the telescopic end of the hydraulic cylinder 51, an upward pulling force can be applied to the connecting base tooth 52, causing the U-shaped crimping member 53 and the rolled edge clamping assembly 56 to move upward. This allows for adjustment of the overall height of the U-shaped crimping member 53 and the rolled edge clamping assembly 56, facilitating the crimping of the wiring terminals. The hydraulic cylinders 51 are installed vertically. There are two hydraulic cylinders 51, and the two hydraulic cylinders 51 are symmetrically installed along the central axis of the U-shaped crimping member 53. The corner of the top of the inner cavity of the U-shaped crimping member 53 is a rounded concave surface.

[0026] The extension end of the hydraulic cylinder 51 drives the U-shaped crimping member 53 to move downward. The two ends of the bottom of the U-shaped crimping member 53 are inclined, so that the opening at the top of the terminal contact the inner side of the U-shaped crimping member 53. As the U-shaped crimping member 53 continues to move downward, the opening at the top of the terminal is subjected to an inward squeezing force. Combined with the fact that the corner of the top of the inner cavity of the U-shaped crimping member 53 is an arc-shaped concave surface, the opening at the top of the terminal is squeezed and bent inward, so that the opening at the top of the terminal is bent and can be easily crimped onto the wire.

[0027] The square insert 54 is installed directly below the U-shaped crimping member 53. The U-shaped crimping member 53 is installed vertically. There are two square inserts 54, and the two square inserts 54 are installed symmetrically along the central axis of the U-shaped crimping member 53.

[0028] The rolled-edge clamping assembly 56 includes a triangular pressure block 561, a snap-fit ​​pad 562, and a screw 563. The triangular pressure block 561 is installed on the top of the inner cavity of the U-shaped crimping member 53. The snap-fit ​​pad 562 is snapped into the middle of the top of the U-shaped crimping member 53. A through hole 564 is opened in the middle of the surface of the snap-fit ​​pad 562. The bottom end of the screw 563 passes through the center of the through hole 564 and extends into the interior of the U-shaped crimping member 53. The bottom end of the screw 563 is threadedly installed between the top of the triangular pressure block 561 and the top of the triangular pressure block 561. A pressing clamp 565 is fixedly connected to the side of the surface of the triangular pressure block 561. The two corners of the top of the triangular pressure block 561 extend to... The interior of the groove 55 allows for a smooth transition between the arc-shaped concave surface at the corner of the U-shaped crimping member 53 and the arc-shaped curved surface of the triangular pressure block 561. After being squeezed and bent by the arc-shaped concave surface at the corner of the U-shaped crimping member 53 through the opening at the top of the terminal, the opening at the top of the terminal continues to be squeezed and bent. The pressing clamp 565 applies radial pressing force to the top of the terminal, causing the top of the terminal to be recessed inward. This results in the wire being subjected to not only axial compression but also radial compression, increasing the contact area between the terminal and the wire, making it less likely for the terminal and the wire to fall off.

[0029] The pointed end of the triangular pressure block 561 faces downward, and the extrusion surfaces on both sides of the surface of the triangular pressure block 561 are arc-shaped surfaces. The two corners at the top of the triangular pressure block 561 extend into the interior of the groove 55. There are four pressing clamps 565, and the four pressing clamps 565 are evenly distributed on the extrusion surface on the outside of the triangular pressure block 561.

[0030] Screw 563 is installed vertically, and screw 563 fixes the snap-fit ​​pad 562 and the triangular pressure block 561 to the U-shaped pressing part 53. There are two screws 563, and the two screws 563 are installed symmetrically along the connecting base teeth 52.

[0031] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown: The rotary feeding mechanism 4 includes a driver 41 and a support shaft 42. The driver 41 is fixedly installed on the top of the inner cavity of the machine body 1. The support shaft 42 is rotatably installed in the middle of the top of the machine body 1 through a bushing. The top of the support shaft 42 is fixedly connected to a worktable 43. A rectangular limiting groove 44 is provided on the side of the top of the worktable 43. A rectangular blind hole 45 is provided on the top of the worktable 43 and near the rectangular limiting groove 44. The rectangular blind hole 45 is located directly below the square insert 54. An air pump 46 is fixedly installed at the bottom of the worktable 43. An air passage 47 is provided inside the worktable 43. When the U-shaped pressing piece 53 moves downward, the square insert 54 moves downward along with it. By inserting the bottom end of the square insert 54 into the rectangular blind hole 45, the U-shaped pressing piece 53 can be supported and limited by the square insert 54, so that the U-shaped pressing piece 53 will not shake or shift.

[0032] The support shaft 42 is installed vertically and directly above the driver 41. The bottom end of the support shaft 42 is fixedly installed to the output end of the top of the driver 41 through a coupling. Rectangular limiting grooves 44 are evenly distributed on the edge of the top of the worktable 43.

[0033] By having the terminal block open upwards and the terminal block fall into the rectangular limiting groove 44, the terminal block can be initially limited. The operator then turns on the suction pump 46 to operate. The suction force of the suction pump 46 draws out the air from the air passage 47. The air inlet of the air passage 47 is at the bottom of the inner cavity of the rectangular limiting groove 44. Under the action of negative pressure, the terminal block in the rectangular limiting groove 44 is sucked and fixed in place.

[0034] The air inlet at the top of the air passage 47 is located at the bottom of the inner cavity of the rectangular limiting groove 44. The air outlet at the bottom of the air passage 47 is connected to the air inlet of the suction pump 46. The suction pump 46 is evenly distributed at the bottom of the worktable 43.

[0035] When a terminal block is placed in the rectangular limiting groove 44 at the top of the workbench 43, and the end of the wire is inserted into the terminal block by an external robotic arm, the driver 41 can be turned on to start working. The rotation of the output end of the driver 41 can drive the support shaft 42 to rotate, which will cause the workbench 43 to rotate together. Combined with the rectangular limiting groove 44 being evenly distributed on the top of the workbench 43, the terminal blocks are fed in an orderly manner.

[0036] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 1 to 9 As shown: A terminal feeder 6 is installed on the side of the top of the machine body 1. The terminal feeder 6 includes a support frame 61. The bottom of the support frame 61 is fixedly installed on the side of the top of the machine body 1. A guide trough 62 is fixedly connected to the top of the support frame 61. A right-angle positioning rod 63 is fixedly connected to the outlet at the bottom of the guide trough 62. A rectangular limiting groove 44 is located between the right-angle positioning rod 63 and the outlet at the bottom of the guide trough 62. A camera 64 is fixedly installed on the side of the surface of the guide trough 62. A controller 65 is fixedly installed at the bottom of the guide trough 62. A strip-shaped hopper 66 is installed at the inlet at the top of the guide trough 62. The end of the inner side of the right-angle positioning rod 63 is fixedly connected to... With rubber baffles 67 attached, the workers fill the inside of the guide trough 62 and the inside of the strip hopper 66 with terminals. By using the inclined installation of the guide trough 62, the terminals in the rectangular limiting groove 44 slide down in an orderly manner. Since the rectangular limiting groove 44 is located between the right-angle positioning rod 63 and the discharge port at the bottom of the guide trough 62, the terminals will fall into the rectangular limiting groove 44. Under the protection of the rubber baffles 67, the terminals will not fall off. As the workbench 43 continues to rotate, the rotational force of the terminals driven by the workbench 43 is greater than the blocking force of the rubber baffles 67, so that the terminals will move and be fed with the rotation of the workbench 43.

[0037] The camera 64 and driver 41 are electrically connected to the controller 65. The guide trough 62 is installed at an angle, and the strip hopper 66 is installed vertically between it and the guide trough 62. The rubber baffle 67 is arc-shaped. The camera 64 rotates the worktable 43, which in turn drives the guide trough 62 to rotate together to capture information. When there are no terminals in the guide trough 62, the camera 64 will transmit the collected information to the controller 65. The controller 65 can then process the signal and control the output of the driver 41 to rotate in the opposite direction. The worktable 43 is driven to rotate in the opposite direction through the support shaft 42, which facilitates the refilling of the empty guide trough 62 and prevents the occurrence of empty material.

[0038] When in use, the staff first fills the inside of the guide trough 62 and the inside of the strip hopper 66 with the wiring terminals, turns on the driver 41 to work, and uses the rotation of the output end of the driver 41 to drive the support shaft 42 to rotate, so that the worktable 43 is driven to rotate together. By using the inclined installation of the guide trough 62, the terminals in the rectangular limiting groove 44 slide down in an orderly manner. Since the rectangular limiting groove 44 is located between the right-angle positioning rod 63 and the discharge port at the bottom of the guide trough 62, the terminals will fall into the rectangular limiting groove 44. Under the obstruction of the rubber baffle 67, the terminals will not detach. As the worktable 43 continues to rotate, the rotational force of the terminals driven by the worktable 43 is greater than the obstruction force of the rubber baffle 67, so the terminals will move and be fed along with the rotation of the worktable 43. Simultaneously, the camera 64 takes pictures and collects information by rotating the worktable 43 and driving the guide trough 62 to rotate together. When there are no wiring terminals in the guide trough 62, the camera 64 will transmit the collected information to the controller 65. The controller 65 can then process the signal and control the output of the driver 41 to rotate in the opposite direction. The worktable 43 is driven to rotate in the opposite direction through the support shaft 42, which makes it easier to refill the empty guide trough 62 and prevents the situation of empty material from occurring. Furthermore, by utilizing the upward opening of the terminal block and the terminal block falling into the rectangular limiting groove 44, the terminal block can be initially limited. The operator then turns on the suction pump 46 to operate, using the suction force of the suction pump 46 to draw out the air in the air passage 47. With the air inlet of the air passage 47 at the bottom of the inner cavity of the rectangular limiting groove 44, under the action of negative pressure, the terminal block inside the rectangular limiting groove 44 is sucked and fixed in place. Furthermore, when the rectangular limiting groove 44 at the top of the worktable 43 has a terminal block, and the end of the wire is inserted into the terminal block by an external robot, the wire and terminal block can be fed as the worktable 43 continues to rotate. When the worktable 43 rotates the terminal block to be crimped to the U-shaped crimping piece 53, the drive 41 can be paused and the worktable 43 can be stopped from rotating. The operator starts the hydraulic cylinder 51 to work. By extending the telescopic end of the hydraulic cylinder 51, a downward pushing force can be applied to the connecting base tooth 52. Through the connection of the connecting base tooth 52, the U-shaped pressing piece 53 and the rolled edge clamping core assembly 56 can move downward together as a whole. By inserting the bottom end of the square insert 54 into the interior of the rectangular blind hole 45, the U-shaped crimping member 53 can be supported and limited by the square insert 54, so that the U-shaped crimping member 53 will not wobble or shift. Furthermore, the extension end of the hydraulic cylinder 51 drives the U-shaped crimping member 53 to move downward. The two ends of the bottom of the U-shaped crimping member 53 are inclined, so that the opening at the top of the terminal contact the inner side of the U-shaped crimping member 53. As the U-shaped crimping member 53 continues to move downward, the opening at the top of the terminal is subjected to an inward squeezing force. Combined with the fact that the corner of the top of the inner cavity of the U-shaped crimping member 53 is an arc-shaped concave surface, the opening at the top of the terminal is squeezed and bent inward, so that the opening at the top of the terminal is bent and can be easily crimped onto the wire. The two corners of the top of the triangular pressure block 561 extend into the interior of the groove 55, so that the arc-shaped concave surface at the corner of the U-shaped crimping member 53 smoothly transitions with the arc-shaped curved surface of the triangular pressure block 561. After the opening at the top of the terminal is squeezed and bent by the arc-shaped concave surface at the corner of the U-shaped crimping member 53, the opening at the top of the terminal continues to be squeezed and bent. The pressing clamp 565 applies radial pressing force to the top of the terminal, causing the top of the terminal to be recessed inward. This means that the wire is not only subjected to axial compression force but also radial compression, increasing the contact area between the terminal and the wire, making it less likely for the terminal and the wire to fall off. After the terminal crimping is completed, the retraction of the extension end of the hydraulic cylinder 51 applies an upward pulling force to the connecting base tooth 52, causing the U-shaped crimping piece 53 and the rolled edge clamping assembly 56 to move upward. This allows the overall height of the U-shaped crimping piece 53 and the rolled edge clamping assembly 56 to be adjusted. The driver 41 is then turned on again, causing the worktable 43 to rotate. The crimped wires are then removed by the external robotic arm, and the water filling process is repeated for batch crimping production.
