Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a cutting device for connector processing. Background Technology

[0002] A connector cutting device is an automated or semi-automatic machine specifically designed for terminal processing in connector production. Its core function is to precisely cut and separate rolls or rows of metal strip terminal raw materials to the exact lengths and specifications required for connector assembly. In connector manufacturing scenarios, whether in consumer electronics, automotive electronics, industrial control, or communication equipment, this device is essential. As connector terminals are core conductive components, their dimensional accuracy and the flatness of the cut surface directly affect the connector's conductivity, mating life, and assembly stability. Manual cutting is not only extremely inefficient and unable to meet the demands of mass production, but also prone to inconsistencies in terminal specifications due to operational errors. This device, through the synergy of its mechanical structure and control system, achieves high-speed, high-precision batch cutting. Simultaneously, it can be combined with a detection module to screen out defective products, effectively ensuring the uniformity of terminal quality. It is an indispensable key processing equipment in the large-scale, standardized production of connectors.

[0003] Traditional connector cutting devices typically rely on the coordinated operation of multiple structures to achieve the desired effect. For feeding, roller or belt feeding structures are commonly used to transport rolls or rows of terminal raw materials to designated positions according to a predetermined length. Positioning components such as locating pins and photoelectric sensors play a crucial role in ensuring precise terminal placement. Power sources are mostly cylinders or motors, which drive the closing of a cutting die consisting of upper and lower dies with shearing blades. The shearing force generated by the die blades severs the connection between the terminal and the raw material strip, completing the cutting. Some devices are also equipped with vision inspection and size sensors to monitor the size and appearance of the cut terminals in real time. Additionally, some devices include a cleaning plate to remove residue from the cutting blades, ensuring cutting accuracy and consistency. The control system, such as a PLC, coordinates the actions of each stage to achieve automated, high-precision terminal cutting, meeting the needs of connector assembly.

[0004] Traditional connector cutting devices have several shortcomings in practical applications. Precision control is limited, relying heavily on mechanical positioning (such as locating pins) and conventional power mechanisms (such as ordinary cylinders). These are susceptible to component wear and material tension fluctuations, leading to significant dimensional deviations in the cutting process, making it difficult to meet the processing requirements of miniaturized, high-precision connector terminals. Regarding cutter head replacement, the fixing method is often a tight bolt-nut connection. Replacing the cutter head requires the use of multiple tools, such as wrenches, to unscrew multiple bolts one by one, a cumbersome and time-consuming process. This significantly slows down production and greatly reduces replacement efficiency, especially when cutter heads wear out frequently and need timely replacement. Furthermore, during the cutting operation, the lack of a buffer component means that when the cutter head lifts upwards after the cutting action, there is no auxiliary thrust provided by the buffer device, limiting the cutter head's return speed. During downward cutting, if misalignment or other abnormalities occur, the cutter head will directly collide rigidly with the worktable, easily damaging the cutter head, shortening its lifespan, and potentially affecting the overall operating accuracy of the cutting device, thereby reducing the cutting quality of the connector terminals. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cutting device for connector processing, which aims to improve the problem that the bolt and nut connection inherent in the cutter head requires the use of multiple tools such as wrenches during disassembly, which slows down the production pace and reduces the efficiency of replacement.

[0007] Furthermore, a cutting frame is fixedly connected to the outer wall of the main block, and a buffer assembly is provided on the inner wall of the cutting frame; the buffer assembly includes a base, the outer wall of the base is fixedly connected to the outer wall of the cutting frame, a protective shell is fixedly connected to the outer wall of the base, a threaded column is fixedly connected to the inner wall of the protective shell, a third spring is fixedly connected to the outer wall of the threaded column, a fixed column is fixedly connected to the top of the third spring, a connecting rod is fixedly connected to the outer wall of the fixed column, a second spring is fixedly connected to the outer wall of the connecting rod, the protective shell is slidably connected to the connecting rod, a buffer head is fixedly connected to the top of the connecting rod, a buffer baffle is fixedly connected to the outer wall of the buffer head, and the cutting frame is slidably connected to the outer wall of the buffer baffle.

[0008] Furthermore, a support column is fixedly connected to the bottom of the workbench, a positioning column is fixedly connected to the outer wall of the workbench, a spherical block is fixedly connected to the outer wall of the positioning column, a positioning plate is fixedly connected to the outer wall of the positioning column, guide blocks are fixedly connected to both ends of the outer wall of the positioning plate, a first screw is threaded to one end of the outer wall of the guide block, a second screw is threaded to the other end of the outer wall of the guide block, a guide wheel is fixedly connected to the outer wall of the positioning plate, and a third screw is threaded to the outer wall of the guide wheel.

[0009] Furthermore, a fixing plate is fixedly connected to the outer wall of the workbench, a fourth screw is threadedly connected to the outer wall of the fixing plate, a first connecting block is fixedly connected to the outer wall of the fixing plate, and a conveying roller is fixedly connected to the outer wall of the first connecting block.

[0010] Furthermore, a fixed shaft is fixedly connected to the inner wall of the workbench, and an associated component is rotatably connected to the outer wall of the fixed shaft. The associated component is cylindrical in shape.

[0011] Furthermore, a first fixing block is fixedly connected to the outer wall of the workbench, and a guide post is fixedly connected to the outer wall of the first fixing block.

[0014] This utility model has the following beneficial effects: 1. In this utility model, pressing the button causes the trapezoidal block to move within the button and cylindrical slider. By adjusting the extension and retraction of the first spring, the compression position can be adjusted according to different needs. The reaction force of the first spring then moves the conical block and crossbar upwards, thereby achieving a limiting and fixing effect on the cutter head. Simultaneously, the cutting operation is completed by driving the cutting device, solving the problem of slowing down production and reducing replacement efficiency in traditional connector cutting devices due to the inherent bolt and nut connection of the cutter head, which requires multiple tools such as wrenches for disassembly. This improves the working efficiency of the device.

[0015] 2. In this utility model, the pressure exerted by the cutter head on the buffer baffle during cutting causes the connected buffer head, connecting rod, and second spring to move within the protective shell, thereby reducing friction between the connecting rod, second spring, and protective shell. Simultaneously, the downward movement of the fixed column drives the third spring to move. When it reaches a certain level, the third spring begins to move in the opposite direction due to its rebound force. This reverse movement of the third spring, in turn, drives the fixed column upward, thereby causing the second spring to move upward and buffer the movement of the buffer baffle. This solves the problem in existing devices where, due to the lack of a buffer component, the cutter head directly collides rigidly with the worktable surface upon completion of the cutting action, causing damage to the cutter head, shortening its service life, and affecting the overall operating accuracy of the cutting device, thus reducing the cutting quality of the connector terminals. This invention extends the service life of the cutter head and improves the cutting accuracy of the device. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-7 An embodiment of this utility model is provided: a cutting device for connector processing, including a workbench 1, a guide plate 20 fixedly connected to the outer wall of the workbench 1, a main block 22 fixedly connected to the outer wall of the guide plate 20, and a snap-on quick-release assembly provided on the inner wall of the main block 22. The snap-on quick-release assembly includes a button 23, the outer wall of which is slidably connected to the inner wall of the main block 22. A cylindrical slider 24 is fixedly connected to the outer wall of the main block 22. A crossbar 25 is slidably connected to the inner wall of the cylindrical slider 24. A conical block 26 is fixedly connected to one side of the outer wall of the crossbar 25. A fifth screw 35 is fixedly connected to the other side of the outer wall of the crossbar 25. A first spring 27 is fixedly connected to the outer wall of the cylindrical slider 24. A third fixing block 28 is fixedly connected to the outer wall of the first spring 27. A second connecting block 29 is fixedly connected to the outer wall of the third fixing block 28. A connecting post 33 is fixedly connected to the outer wall of the second connecting block 29.

A trapezoidal block 30 is fixedly connected to the top of the push rod 31. A blade 34 is slidably connected to the inner wall of the second connecting block 29.

[0020] Specifically, firstly, by pressing button 23, the trapezoidal block 30 moves within button 23 and cylindrical slider 24, allowing for convenient adjustment of the extension and retraction of the first spring 27 to accommodate different degrees of compression, thus achieving initial positioning of the blade. During the cutting operation, the connector terminal to be cut is placed below the blade 34. At this time, button 23 is pressed down to compress the first spring 27. Then, the blade 34 is secured inside the second connecting block 29 via the third fixing block 28 and the lower second connecting block 29. After the conical block 26 reaches between the trapezoidal block 30 and the bottom block 32 via both sides of the trapezoidal block 30, button 23 is released. The first spring 27 releases its elastic force, driving the conical block 26 and the connected crossbar 25 to move automatically upwards. The conical block 26 is then fixed to the bottom of the trapezoidal block 30 via the trapezoidal block 30, thereby firmly fixing the blade 34 below the second connecting block 29.

The buffer assembly includes a base 43, the outer wall of which is fixedly connected to the outer wall of the cutting frame 44. A protective shell 38 is fixedly connected to the outer wall of the base 43. A threaded post 42 is fixedly connected to the inner wall of the protective shell 38. A third spring 41 is fixedly connected to the outer wall of the threaded post 42. A fixing post 40 is fixedly connected to the top of the third spring 41. A connecting rod 37 is fixedly connected to the outer wall of the fixing post 40. A second spring 39 is fixedly connected to the outer wall of the connecting rod 37. The connecting rod 37 is slidably connected. The system includes a protective shell 38, a buffer head 36 fixedly connected to the top of a connecting rod 37, a buffer baffle 45 fixedly connected to the outer wall of the buffer head 36, a cutting frame 44 slidably connected to the outer wall of the buffer baffle 45, a support column 2 fixedly connected to the bottom of the worktable 1, a positioning column 9 fixedly connected to the outer wall of the worktable 1, a spherical block 10 fixedly connected to the outer wall of the positioning column 9, a positioning plate 3 fixedly connected to the outer wall of the positioning column 9, guide blocks 4 fixedly connected to both ends of the outer wall of the positioning plate 3, a first screw 5 threadedly connected to one end of the outer wall of the guide block 4, and a second screw 6 threadedly connected to the other end of the outer wall of the guide block 4. A guide wheel 7 is fixedly connected to the outer wall of the positioning plate 3, and a third screw 8 is threadedly connected to the outer wall of the guide wheel 7. A fixing plate 11 is fixedly connected to the outer wall of the worktable 1, and a fourth screw 12 is threadedly connected to the outer wall of the fixing plate 11. A first connecting block 13 is fixedly connected to the outer wall of the fixing plate 11, and a conveyor roller 14 is fixedly connected to the outer wall of the first connecting block 13. A fixing shaft 15 is fixedly connected to the inner wall of the worktable 1, and an associated component 16 is rotatably connected to the outer wall of the fixing shaft 15. The associated component 16 is cylindrical. A first fixing block 17 is fixedly connected to the outer wall of the worktable 1. A guide post 18 is fixedly connected to the outer wall. The guide post 18 is cylindrical. Guide tubes 19 are fixedly connected to both sides of the outer wall of the guide post 18. The guide tubes 19 are cylindrical. A second fixing block 21 is fixedly connected to the outer wall of the main block 22. The second fixing block 21 is rectangular. A guide plate 20 is fixedly connected to the second fixing block 21. The guide plate 20 is plate-shaped. A buffer baffle 45 is located below the blade 34. The buffer baffle 45 is plate-shaped. A buffer head 36 is fixedly connected to the inner wall of the buffer baffle 45 with a groove. A threaded post 42 is threaded.

[0022] Specifically, during the cutting process, the lower blade presses down on the buffer baffle 45, causing the connected buffer head 36 to drive the connecting rod 37 and its second spring 39 to move synchronously in opposite directions. As the second spring 39 moves the lower fixed post 40 downwards, it in turn moves the third spring 41 synchronously. Once the pressure on the third spring 41 reaches a certain point, it begins to rebound. Simultaneously, the reverse movement of the third spring 41 further drives the fixed post 40 and its second spring 39 to move, thus causing the entire buffer baffle 45 to rebound.

[0023] Working principle: When the device is used to cut connectors, one end of the connector is first inserted through two small holes inside the guide block 4 located on the upper part of the positioning plate 3. Then, the internal motor is started. Driven by the motor, the groove on the guide wheel 7 clamps the wire by friction and conveys it to the other end according to the set length and speed. Then, it passes out through the small hole at the other end. Next, the connector enters through two small holes in the conveyor roller 14 located at one end of the first connecting block 13. Then, it passes through the gap between the upper and lower related parts 16 at one end of the fixed shaft 15 for stripping. Then, it moves along the guide tubes 19 at both ends of the guide post 18. When it reaches the designated area, the blade 34 located inside the cutting frame 44 quickly cuts under the command of the control system to remove the connector insulation. Meanwhile, the buffer assembly located below the blade 34, after being subjected to pressure from the blade 34, transmits the pressure to the buffer head 36 at the lower part via the buffer baffle 45. Then, the buffer head 36 drives the connecting rod 37 and the second spring 39, which are fixedly connected to it, to move downwards synchronously. The pressure from the second spring 39 forces the fixed column 40 to move downwards, thereby driving the third spring 41 to move synchronously. When the third spring 41 is pressed down to the critical point of the spring, the third spring 41 begins to rebound. At the same time, due to the rebound of the third spring 41, the fixed column 40 and the second spring 39 are driven upwards. Then, the entire buffer baffle 45 will rebound to buffer the blade 34. Meanwhile, the control panel located on the worktable 1 can automatically adjust and set parameters such as stripping length, speed, and cutting depth. Then, the internal PLC receives and processes these parameters, thereby controlling the coordinated operation of each component to finally realize the automated stripping of the connector. Finally, the processed connector flows out through the gap between the two associated components 16 at the other end and enters the collection box.
