[0037] In one embodiment of this utility model, such as Figures 1-5As shown, a cable terminal crimping mechanism is provided, including a crimping assembly 10, a transmission assembly 20, and a drive assembly 30. The crimping assembly 10 includes a lower cutter holder 12 and an upper cutter holder 11. The transmission assembly 20 includes a first pressure rod 21, a second pressure rod 22, and a hollow assembly block 23. The first pressure rod 21 and the second pressure rod 22 are coaxially connected through the hollow assembly block 23. A pressure sensor 24 is provided inside the hollow assembly block 23. The connecting end of the pressure sensor 24 abuts against the first pressure rod 21, and the force-bearing end abuts against the second pressure rod 22. The end of the first pressure rod 21 away from the hollow assembly block 23 is connected to the upper cutter holder 11. The output end of the drive assembly 30 is connected to the end of the second pressure rod 22 away from the hollow assembly block 23 and can drive the upper cutter holder 11 to move up and down relative to the lower cutter holder 12 in the vertical direction. Specifically, this embodiment also provides a conveying assembly (not shown in the figure). The conveying assembly includes a feeding fixture and a three-axis drive device. The fixture is used to fix the ribbon cable to be crimped. The three-axis drive device can drive the fixture to move a single core wire in the ribbon cable relative to the lower cutter holder 12 in the X-axis direction, lift and lower in the Z-axis direction, and push and pull in the Y-axis direction. Preferably, three sets of X, Y, and Z linear modules are used to achieve the drive, which is simple in structure and easy to install. The lower cutter holder 12 is provided with a lower blade and a lower wire separator arranged sequentially from the inside to the outside along the axial direction of the core wire. The lower blade has a function. The cutting edge at the connection between the terminal and the terminal strip has a U-shaped groove in the lower wire divider. The wiring harness is moved by the X-axis and Z-axis of the three-axis drive device to realize the replacement between two adjacent core wires (i.e., the core wire that has been crimped moves out of the U-shaped groove and the core wire to be crimped moves into the U-shaped groove), and is pushed in and pulled out towards or away from the lower blade by the Y-axis movement. Correspondingly, the upper blade holder 11 is provided with an upper blade and an upper wire divider. The upper blade has a cutting edge that acts on the terminal and the wiring harness, and the upper wire divider has a U-shaped groove. When the mold is closed, the upper wire divider and the lower wire divider act on the core wire respectively.

[0038] In one embodiment of this utility model, such as Figures 3-4As shown, the hollow assembly block 23 includes a first block 231 and a second block 232 connected together. The first block 231 has a first through hole and a first groove located at the inner end of the first through hole. The top end of the first pressure rod 21 passes through the first through hole and its end has a first mounting platform 211 adapted to the first groove. The second block 232 has a second through hole and a second groove located at the inner end of the second through hole. The bottom end of the second pressure rod 22 passes through the second through hole and its end has a second mounting platform 221 adapted to the second groove. The connecting end of the pressure sensor 24 abuts against the first mounting platform 211 and the force-bearing end abuts against the second mounting platform 221. Specifically, the pressure sensor 24 is a CYT-206 miniature pressure sensor 24 produced by Tianyu Hengchuang Company. When the upper tool holder 11 and the lower tool holder 12 are closed, the drive assembly 30 applies downward pressure to the first pressure rod 21 and the second pressure rod 22 in the vertical direction. The contact between the upper tool holder 11 and the lower tool holder 12 applies upward reaction force to the first pressure rod 21 and the second pressure rod 22 in the vertical direction. Thus, the pressure sensor 24 is used to detect the impact force of this downward press. In this embodiment, the first block 231 and the second block 232 are detachably connected by screws, which facilitates the assembly of the pressure sensor 24. The first mounting platform 211 and the second mounting platform 221 are both cylindrical mounting platforms. Furthermore, the inner ends of the first block 231 and the second block 232 are respectively provided with semi-circular through holes to avoid the signal lines of the pressure sensor 24. The structure is simple and convenient for inspection and maintenance.

[0039] In one embodiment of this utility model, such as Figures 3-4 As shown, the transmission assembly 20 further includes a lifting slider 25 and a fine-tuning structure 26. The rear side of the lifting slider 25 is connected to the drive assembly 30, and the front side is connected to the top of the second pressure rod 22. The fine-tuning structure 26 is disposed on the lifting slider and can adjust the height of the upper tool holder 11 relative to the lower tool holder in the vertical direction. Specifically, by using the fine-tuning structure 26 to adjust the height of the upper tool holder 11 relative to the lower tool holder in the vertical direction, the purpose of fine-tuning the mold closing stroke can be achieved. This allows for fine-tuning to achieve the required mold closing stroke, which helps to broaden the applicability of this embodiment.

[0040] In one embodiment of this utility model, such as Figures 3-4As shown, the front side of the lifting slider 25 has a first boss and a second boss protruding outwards. A hollow groove 251 is formed between the first boss and the second boss. The second pressure rod 22 is a threaded rod. The top end of the threaded rod passes through the first boss and the hollow groove 251, and its end is screwed to the second boss. The fine-tuning structure 26 is a threaded ring located in the hollow groove 251. The bottom end of the threaded ring abuts against the first boss, and the top end abuts against the second boss. The threaded ring is threadedly engaged with the threaded rod. Specifically, the second boss has a threaded hole facing the hollow groove 251. By turning the threaded ring, the threaded ring remains stationary relative to the hollow groove 251. The threaded hole on the second boss drives the second pressure rod 22 to move axially relative to the lifting slider 25, thereby fine-tuning the relative height of the upper tool holder 11 and the lower tool holder 12 in the vertical direction.

[0041] In one embodiment of this utility model, such as Figures 3-4 As shown, the outer side of the threaded ring is provided with several insertion holes. Specifically, the outer annular array of the threaded ring has six insertion holes. During adjustment, a rod-shaped wrench needs to be inserted into the insertion hole, and force is applied to the rod-shaped wrench in the circumferential direction, thereby driving the threaded ring to rotate in the forward or reverse direction. The structure is simple and easy to operate.

[0042] In one embodiment of this utility model, such as Figures 3-4 As shown, the bottom end of the first boss has a rectangular groove with an open bottom, and the hollow assembly block 23 is a rectangular block that fits into the rectangular groove. Specifically, during adjustment, the second mounting platform 221 of the second pressure rod 22 rotates and engages with the second groove, using the rectangular groove to restrict the hollow assembly block 23 from being driven by the rotational force, thereby preventing the upper tool holder 11 and the lower tool holder 12 from shifting during fine adjustment, which helps to ensure the accuracy of machining.

[0043] In one embodiment of this utility model, such as Figure 1 , 4As shown in Figure 5, the assembly also includes a frame assembly 40. The end-cutting assembly 10 is located at the bottom of the frame assembly 40. The top of the frame assembly 40 is provided with a connecting seat 41. The front side of the connecting seat 41 has a vertical groove 411 that slides with the lifting slider 25, and the rear side has a circular through hole 412. The lifting slider 25 has a horizontal groove on the side near the circular through hole 412. A swing block 413 is provided in the horizontal groove. An eccentric rotating shaft 4131 is provided at the center of the swing block 413. The output end of the drive assembly 30 passes through the circular through hole 412, and its end has a concentric rotating shaft. A swing rod is connected to the concentric rotating shaft. The other end of the swing rod is connected to the eccentric rotating shaft 4131 and can drive the eccentric rotating shaft 4131 to make a circular motion around the center of the circular through hole. Specifically, the drive assembly 30 includes a servo motor and a right-angled hollow rotating platform. The coaxial shaft is connected to the servo motor via the right-angled hollow rotating platform. During operation, the eccentric shaft is driven by the swing arm to revolve around the center of the circular through hole 412. During the revolution, the lateral movement is performed by the swing block 413 and the horizontal slide rail, and the vertical movement is performed by the lifting slider 25 and the vertical slide rail 411, thereby converting the rotational motion into linear motion. Compared with hydraulic cylinder drive, the servo motor can achieve more precise control.

[0044] In one embodiment of this utility model, such as Figure 2 As shown, the terminal crimping assembly 10 also includes an assembly base 13 mounted on the frame assembly 40 and an unwinding shaft for providing terminal strip. The bottom of the assembly base 13 has a feed groove 131 through which the terminal strip passes. The lower cutter holder 12 is located at the outlet end of the feed groove 131. The top of the assembly base 13 has a vertically arranged guide groove, and a guide block 132 is provided within the guide groove. The top end of the guide block 132 is connected to the bottom end of the first pressure rod 21, and the upper cutter holder 11 is located at the bottom end of the guide block 132. Specifically, the assembly base 13 is L-shaped. The horizontal section of the assembly base 13 has a terminal crimping receiving platform. The feed groove 131 and the lower cutter holder 12 are both located on the terminal crimping receiving platform. The vertical section of the assembly base 13 extends outward to form a connecting platform. The guide groove is vertically located on the connecting platform, and the guide block 132 slides vertically up and down with the connecting platform via the guide groove.

[0045] In one embodiment of this utility model, such as Figure 2As shown, the terminal assembly 10 also includes a swing arm 15, a feeding claw 151, a first tension spring (not shown) and a second tension spring (not shown). The top end of the swing arm 15 is swayably connected to the top of the mounting base 13 and has a connecting vertical cam groove 152 and an inclined cam groove 153. The feeding claw 151 is swayably located at the bottom end of the swing arm 15, and its feeding end can act on the terminal strip located in the feed groove 131. The side of the guide block 132 extends outward with a... The rolling cam 133 is capable of rolling cooperation with the protrusion and the vertical cam groove 152 and the inclined cam groove 153. One end of the first tension spring is connected to the swing arm 15 and the other end is connected to the frame assembly 40, and it can continuously provide the swing arm 15 with an outward swinging elastic force. One end of the second tension spring is connected to the feeding claw 151 and the other end is connected to the frame assembly 40, and it can continuously provide the feeding end of the feeding claw 151 with an elastic force to keep it in contact with the terminal strip. Specifically, the vertical section of the mounting base 13 is provided with a rotating shaft connected by a swing arm 15 and an L-shaped rod for fixing the first tension spring. The L-shaped rod has a first hole. The side of the swing arm 15 extends outward with a first connecting piece, which has a second hole and a third hole. The free end of the feeding claw 151 extends outward with a second connecting piece, which has a fourth hole. One end of the first tension spring is fixed to the second hole and the other end is fixed to the first hole, thereby continuously providing the swing arm 15 with an outward elastic force. When the cam 133 is located in the vertical roller groove, the first tension spring is in tension assembly, and the second tension spring... One end of the claw is fixed to the third hole and the other end is fixed to the fourth hole, thereby providing the claw 151 with a continuous elastic force to swing and press down towards the end of the terminal strip. During operation, the claw 151 aligns with the rectangular positioning hole on the terminal strip. When the guide block 132 presses down, it drives the cam 133 to roll along the vertical cam groove 152 and the inclined cam groove 153. The second tension spring is stretched, and under the action of the swing arm 15, it drives the claw 151 to swing upward and forward, thereby realizing the pushing of the terminal strip. When the guide block 132 rises, the second tension spring is released, thereby driving the claw 151 to swing inward and reset.

[0046] In one embodiment of this utility model, it further includes an information processor, a driver, and an alarm. The pressure sensor 24 and the driver are electrically connected to the information processor, and the alarm is electrically connected to an external power supply through the driver. Specifically, it also includes a display screen electrically connected to the driver. The display screen is located on the front of the frame assembly 40 and feeds back the impact pressure of multiple presses to the operator in the form of data, facilitating the operator's adjustment and maintenance. The alarm is a three-color alarm light located on the frame assembly 40. The information processor contains a database of qualified pressure parameters. It should be noted that the database needs to be set according to actual conditions, such as customer requirements and enterprise standards. The reference parameter group in the database is not a necessary technical point for implementing this embodiment. Therefore, those skilled in the art only need to determine the threshold range of the required pressure parameters according to actual conditions to implement this technical solution. When the press pressure parameter does not meet the standard set in the aforementioned database, the driver transmits an electrical signal to the three-color alarm light to activate the alarm and remind the operator. The driver also transmits an electrical signal to the drive assembly 30 to stop working, and the equipment stops working.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
