Description

Technical Field

[0001] This invention belongs to the field of automated assembly equipment technology, and particularly relates to an automatic terminal cutting and insertion device and method. Background Technology

[0002] In automotive electronic connector assembly processes, particularly for automotive Ethernet terminals, existing technologies primarily rely on multiple independent workstations to complete the process step-by-step. This workflow requires bending and shaping the terminals before cutting and insertion, which takes place in multiple workstations and steps. Because the bent sections of the terminals are relatively long and the clamping positions are limited, assembly faces challenges in material handling and obstacle avoidance by the insertion mechanism.

[0003] The existing assembly process has the following significant drawbacks: 1. It requires the collaboration of multiple workstations, involving multiple product handling and positioning operations, resulting in a complex, time-consuming, and labor-intensive assembly process with unstable quality and a tendency to malfunction; 2. It has high labor costs, is difficult to maintain, and has low production capacity, failing to meet the demands of modern large-scale and high-efficiency production; 3. Due to the special structure of the terminals, traditional mechanisms are difficult to apply directly, and there is a lack of an integrated device that can stably and efficiently complete the cutting and insertion of these specific terminals.

[0004] Therefore, there is an urgent need to develop a device and method that can overcome the above problems and achieve stable, efficient and automated assembly. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic terminal cutting and insertion device and method. It aims to solve the problems of low efficiency, high cost, and unstable quality of existing manual assembly processes, as well as the difficulties in material handling and avoidance by the automated mechanism due to the special structure of the terminals. The invention achieves automated cutting and insertion of terminals, improves production capacity and quality, and reduces manufacturing costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic terminal cutting and insertion device includes a base, a cutting mechanism, a receiving mechanism, and an insertion mechanism. The cutting mechanism is installed on the upper end of the base and is used to cut individual terminals from a terminal strip. The receiving mechanism and the insertion mechanism are installed on the lower end of the base and are used to receive the terminals cut by the cutting mechanism and insert them into predetermined positions.

[0008] The cutting mechanism, receiving mechanism, and insertion mechanism work together on the base to complete the three processes of cutting, receiving, and inserting the terminals in the same station.

[0009] The insertion mechanism includes a support, a first linear motion module, a movable plate, a clamping cylinder, a lower slide block, a receiving limit assembly, and a terminal fixing assembly. The support is installed at the lower end of the base. The first linear motion module is installed on the support and is used to drive the movable plate to reciprocate along the receiving and insertion direction. The movable plate is installed on the output end of the first linear motion module and is used to support and drive all components installed on it to move. The clamping cylinder is installed at one end of the movable plate, and the lower slide block is installed at the output end of the clamping cylinder. It is used to move laterally under the drive of the clamping cylinder to clamp and release the terminal. The receiving limit assembly is installed on the lower slide block and is used to accurately position and lock the receiving mechanism during the insertion process. The terminal fixing assembly is installed at the end of the lower slide block away from the clamping cylinder and is used to clamp and fix the terminal together with the receiving mechanism during the insertion process.

[0010] The receiving mechanism includes a receiving cylinder fixedly installed on the movable plate, a receiving slider installed at the output end of the receiving cylinder, and a receiving head installed on the upper end of the receiving slider. The receiving cylinder is used to drive the receiving slider and the receiving head to rise and fall vertically to receive the terminals cut by the cutting mechanism. The receiving head is used to carry the terminals cut by the cutting mechanism. Under the joint clamping of the receiving head and the terminal fixing assembly, the terminals are driven by the first linear motion module to move the movable plate, thereby completing the insertion action.

[0011] Furthermore, the receiving limiting assembly includes a limiting cylinder fixedly installed on the lower slider, a limiting slider fixedly installed on the output end of the limiting cylinder, and a limiting head fixedly installed on the limiting slider. The limiting cylinder is used to drive the limiting head to move laterally. A third support block for supporting the sliding of the limiting slider is also installed on the lower slider. The limiting head is used to be inserted into the receiving slider before insertion to achieve vertical limiting of the receiving slider.

[0012] Furthermore, the terminal fixing assembly includes a connecting block fixedly mounted on the lower slider, a fixing block slidably mounted on the connecting block, and a third damping member disposed between the connecting block and the fixing block; the fixing block has a protruding fixing part, and the connecting block has a fixing groove corresponding to the fixing part; the terminal fixing assembly is driven to move laterally as a whole by the clamping cylinder, so that the fixing block contacts the terminal on the receiving head under the action of the third damping member and applies an elastic clamping force, thereby cooperating with the receiving head to clamp the terminal during the insertion process.

[0013] Furthermore, the receiving slider has a slot for cooperating with the receiving limiting component to achieve vertical limiting, and the receiving head has a receiving part for accurately bearing and positioning the terminal.

[0014] Furthermore, a fourth support block is also installed on the movable plate to support the sliding of the receiving slider, so as to provide guidance and support for the lifting and lowering movement of the receiving slider.

[0015] Furthermore, the cutting mechanism includes a cutting cylinder, a connecting rod, an upper slider, a mounting block, an upper cutting blade, and a lower cutting blade. The first end of the connecting rod is hinged to the cutting cylinder, and the second end is hinged to the upper slider. The body portion between the first and second ends of the connecting rod is hinged to the mounting block. Both the cutting cylinder and the mounting block are fixedly mounted on the base. The cutting cylinder drives the connecting rod to rotate, which is converted into linear motion of the upper slider. The upper cutting blade is fixedly mounted on the upper slider, and the lower cutting blade is fixedly mounted on the base at the end opposite to the upper cutting blade. The upper and lower cutting blades cooperate to complete the terminal cutting.

[0016] Furthermore, a blade holder is fixedly installed between the upper slider and the upper cutting blade. The blade holder is also equipped with an upper pressure block and at least one positioning pin. A sliding groove is provided on the blade holder. The upper pressure block is slidably installed on the blade holder, and a spring is installed on the upper end of the upper pressure block. The other end of the spring abuts against the upper slider to provide downward pressing force for the upper pressure block. The positioning pin is fixedly installed through the blade holder and is used to insert into the positioning hole of the terminal material strip before cutting to achieve precise positioning. A limit groove is provided on the upper pressure block, and a corresponding limit post is provided on the blade holder that can slide on the limit groove to limit the movement range of the upper pressure block and ensure its pressing stroke is stable.

[0017] Furthermore, a first support block is fixedly installed on the mounting block, and the upper slider is slidably installed on the first support block. The first support block provides guidance for the movement of the upper slider. Stops are installed at both ends of the first support block, and first damping elements are correspondingly installed at both ends of the upper slider. The stops cooperate with the first damping elements to absorb impacts and limit the movement range of the upper slider.

[0018] Furthermore, a second support block for supporting the sliding of the lower slider is fixedly installed on the movable plate, and a second damping element is installed on the lower slider corresponding to the second support block. The second support block provides guidance for the lateral movement of the lower slider, and the second damping element is used to buffer and reduce shock when the lower slider moves to its extreme position.

[0019] An automatic terminal cutting and insertion method, using the aforementioned automatic terminal cutting and insertion device, includes the following steps:

[0020] S1. The starting device, the first linear motion module drives the movable plate and its components to move below the terminal, and then the receiving cylinder drives the receiving slider and receiving head to rise to near the terminal.

[0021] S2. The cutting cylinder drives the connecting rod to rotate and causes the upper slider and the upper components to move down continuously. The positioning pin first inserts into the positioning hole of the terminal strip, then the pressure block presses the terminal strip, and finally the upper cutting blade cuts the terminal and places it on the receiving head.

[0022] S3. The receiving cylinder drives the receiving slider, receiving head and its terminals to move down a certain distance, and then the clamping cylinder drives the lower slider and its connecting block and fixing block to move close to the terminals to press the terminals.

[0023] S4. The limit cylinder drives the limit slider and the limit head to move until the limit head enters the slot of the receiving slider;

[0024] S5. The first linear motion module drives the movable plate and its components to continue moving, so that the terminal insertion is completed;

[0025] S6. Each mechanism is reset in sequence, and the cycle begins again.

[0026] Compared with existing technologies, the beneficial effects of this technology are:

[0027] This invention integrates cutting, receiving, and insertion functions into one unit, achieving full automation of terminal cutting and insertion, significantly reducing manual labor and manufacturing costs. The integrated structure reduces the number of product handovers and potential damage during handovers, significantly improving production capacity and product quality, while also facilitating equipment maintenance. The cutting mechanism uses a linkage transmission structure, combined with positioning pins and elastic pressure blocks, to achieve precise terminal positioning and stable cutting, ensuring cutting accuracy. The receiving mechanism works in conjunction with the insertion mechanism, receiving the cut terminals through a receiving head, and then clamping the terminals with a terminal fixing component for insertion, effectively solving the problems of difficulty in clamping long terminals and difficulty in mechanism avoidance after insertion. The streamlined and durable mechanism reduces product handling stations, improving production efficiency and equipment operational stability. Attached Figure Description

[0041] 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.

[0042] like Figures 1-9 As shown, this embodiment of the invention provides an automatic cutting and insertion device for terminal 5, which is mainly used for the automatic cutting and insertion of automotive Ethernet series terminals 5.

[0043] The device includes a base 1 and a cutting mechanism 2, a receiving mechanism 4, and an insertion mechanism 3 that work together on the base 1. The cutting mechanism 2 is installed at the upper end of the base 1, while the receiving mechanism 4 and the insertion mechanism 3 are installed at the lower end of the base 1, forming a layered layout structure. This makes full use of space and ensures the coordinated operation between the mechanisms, enabling the cutting, receiving, and insertion of terminals to be completed at the same workstation.

[0044] The base 1 serves as the installation foundation for the entire device. It is made of high-strength aluminum alloy, which has good rigidity and stability, and can ensure the accuracy of operation of each mechanism.

[0045] The cutting mechanism 2 is used to cut the terminal 5 from the terminal strip. The cutting mechanism 2 includes a cutting cylinder 21, a connecting rod 22, an upper slider 23, a mounting block 24, an upper cutting blade 25, and a lower cutting blade 26. The connecting rod 22 is elongated, with its first end hinged to the piston rod of the cutting cylinder 21, its second end hinged to the upper slider 23, and the body portion between the first and second ends of the connecting rod 22 hinged to the mounting block 24, forming a lever transmission structure. Since the piston rod of the cutting cylinder 21 is a standardized structure without a hinge, it is hinged to the connecting rod 22 by a concave part. The cutting cylinder 21 drives the connecting rod 22 to rotate, which is converted into linear motion of the upper slider 23. The upper cutting blade 25 and the lower cutting blade 26 cooperate to complete the cutting of the terminal 5.

[0046] The cutting cylinder 21 serves as the power source, and both it and the mounting block 24 are vertically fixed to the base 1. The upper cutting blade 25 is fixedly mounted to the lower end of the upper slider 23, and the lower cutting blade 26 is fixedly mounted to the base 1 at the end opposite to the upper cutting blade 25. The mounting block 24 is a rectangular plate-shaped component, its bottom fixed to the base 1 by bolts, and a reinforcing rib is installed at one end to strengthen vertical fixation. Both the upper cutting blade 25 and the lower cutting blade 26 are block-shaped, and they cut the terminal strip through mutual shearing force. The upper cutting blade 25 and the lower cutting blade 26 are fixed by fixing plates. Preferably, the upper cutting blade 25 and the lower cutting blade 26 are made of high-hardness alloy steel, and the cutting edges are precision ground to ensure cutting quality.

[0047] When the piston rod of the cutting cylinder 21 extends, it drives the connecting rod 22 to rotate around its hinge point with the mounting block 24, thereby causing the upper slider 23 to move downward, so that the upper cutting blade 25 and the lower cutting blade 26 cooperate to complete the cutting action of the terminal 5. This connecting rod 22 transmission structure can convert the linear motion of the cylinder into the vertical motion of the upper slider 23, and has a force-amplifying effect, ensuring a stable output of cutting force.

[0048] Furthermore, a block-shaped blade holder 27 is fixedly installed between the upper slider 23 and the upper cutting blade 25. The blade holder 27 also has an upper pressure block 271 and at least one positioning pin 272. The main function of the blade holder 27 is to support and install the various components. The upper pressure block 271 can press the strip before it cuts the terminal 5, preventing displacement of the strip during the cutting process and thus affecting the cutting accuracy of the terminal 5. Specifically, a vertical groove is formed through the blade holder 27. The upper pressure block 271 is slidably installed in this groove, and a spring 273 is installed at the upper end of the upper pressure block 271. The other end of the spring 273 abuts against the lower end face of the upper slider 23 to provide downward pressure force to the upper pressure block 271. By setting a spring 273 on the upper pressure block 271, it can play a buffering role when it is pressed against the material belt, so as to prevent the impact damage caused by the rapid pressing against the material belt without buffer. In addition, as the upper pressure block 271 is pressed against the material belt and descends continuously, the spring 273 is continuously compressed. Under the relative force, the upper pressure block 271 can strengthen the pressing of the material belt.

[0049] The positioning pin 272 is a long cylindrical component that runs through the cutter holder 27 from top to bottom and is fixedly installed. Its lower end extends out of the lower end face of the cutter holder 27. The positioning pin 272 is inserted into the positioning hole on the material strip before the upper pressure block 271 presses the material strip to achieve precise positioning and restrict the material strip from continuing to flow forward.

[0050] During the cutting process, the upper slider 23 drives the cutter holder 27 to move downwards. The positioning pin 272 first inserts into the positioning hole of the terminal strip to achieve precise positioning of the terminal 5. Then, the upper pressure block 271 contacts and presses the terminal strip to prevent the terminal 5 from shifting during the cutting process. Finally, the upper cutting blade 25 and the lower cutting blade 26 cooperate to complete the cutting. The spring 273 enables the upper pressure block 271 to provide elastic clamping force, which ensures the clamping effect and avoids damaging the terminal 5.

[0051] Furthermore, the upper pressure block 271 is provided with a racetrack-shaped limiting groove 274, and the cutter holder 27 is provided with a corresponding limiting post 275 that can slide on the limiting groove 274, which is used to limit the movement range of the upper pressure block 271, prevent the upper pressure block 271 from falling off the cutter holder 27 and precisely limit its up and down movement range.

[0052] A first support block 241 is fixedly mounted on the mounting block 24 to guide the movement of the upper slider 23, which is slidably mounted on the first support block 241. The first support block 241 has a slot that matches the upper slider 23 to support its sliding. A stop block 242 is provided at the edge of the slot of the first support block 241 to restrict the upper slider 23 from falling outward. At the same time, the stop block 242 can be detachably installed on the first support block 241 by bolts for easy disassembly and maintenance.

[0053] Stoppers 242 are fixedly installed on both sides of the upper end of the first support block 241, and first damping elements 231 are correspondingly installed on both sides of the upper end of the upper slider 23. The stoppers 242 and the first damping elements 231 cooperate to limit the downward movement range of the upper slider 23 and play a role in buffering and shock absorption, thereby improving the smoothness of the mechanism's operation. Specifically, the first damping element 231 is preferably a rubber block.

[0054] The insertion mechanism 3 is used to insert the cut terminals 5 into predetermined positions in the connector housing. The insertion mechanism 3 includes a support 31, a first linear motion module 32, a movable plate 33, a clamping cylinder 34, a lower slider 35, a receiving and limiting assembly 36, and a terminal fixing assembly 37. The first linear motion module 32 is a modular execution unit that converts the rotational motion of a motor into high-precision linear motion. It includes a linear guide slider, a transmission assembly, a drive motor, a limiting and sensing assembly, and a protective assembly, used to drive the movable plate 33 to reciprocate along the receiving and insertion direction. The movable plate 33 is rectangular and mainly used to support and drive the movement of all components mounted on it.

[0055] An L-shaped support 31 is fixedly installed at the lower end of the base 1. The first linear motion module 32 is horizontally fixedly installed on the support 31. The movable plate 33 is installed on the output end of the first linear motion module 32, i.e., the slide, and can reciprocate in the horizontal direction under the drive of the first linear motion module 32.

[0056] The clamping cylinder 34 is fixedly installed at one end of the movable plate 33, and the lower slider 35 is installed on the output end of the clamping cylinder 34. That is, one end of the lower slider 35 is connected to the piston rod of the clamping cylinder 34, and can move horizontally under the drive of the clamping cylinder 34 to achieve the clamping and release of the terminal 5.

[0057] In this embodiment, a biting block is fixedly installed on the piston rod of the clamping cylinder 34, and a biting groove is correspondingly opened at one end of the lower slider 35. The clamping cylinder 34 is connected to the lower slider 35 through the biting block.

[0058] The receiving limit assembly 36 is installed on the lower slider 35, and the terminal fixing assembly 37 is installed on the lower slider 35 at the end away from the clamping cylinder 34.

[0059] Furthermore, a second support block 351 is fixedly installed on the movable plate 33 to support the sliding of the lower slider 35, providing guidance for the lateral movement of the lower slider 35; a second damping element 352 is installed on the lower slider 35 at the end face corresponding to the second support block 351, which is used to buffer and reduce shock when the lower slider 35 moves to its extreme position, thereby improving the stability of the movement of the lower slider 35.

[0060] The lower slider 35 is T-shaped, with its outwardly extending ends used to mount the second damping element 352. The position of the second damping element 352 is exactly opposite to the end face of the second support block 351, providing a buffering effect when the clamping cylinder 34 extends outward, protecting the lower slider 35 from collision damage with other components. In this embodiment, the second damping element 352 is also a rubber block. A rectangular groove runs through the middle of the lower slider 35 to reduce its weight and lower the load on the clamping cylinder 34.

[0061] The receiving limiting assembly 36 includes a limiting cylinder 361 fixedly mounted on the lower slider 35 for driving the limiting head 363 to move laterally; a limiting slider 362 fixedly mounted on the output end of the limiting cylinder 361; and a limiting head 363 fixedly mounted on the upper end of the limiting slider 362 for vertical limiting of the receiving slider 42. In addition, a third support block 364 is also mounted on the lower slider 35 to support the sliding of the limiting slider 362. The receiving limiting assembly 36 is used to precisely limit and lock the receiving slider 42 during the insertion of the terminal 5, preventing the receiving head 43 from shifting and ensuring insertion accuracy. The limiting slider 362 and the third support block 364 are fitted together, and the limiting cylinder 361 and the limiting slider 362 are connected by a locking block. The part of the limiting head 363 that contacts the receiving slider 42 has a cylindrical structure, allowing it to easily slide into the slot 421 on the receiving slider 42 to limit the position of the receiving slider 42.

[0062] The terminal fixing assembly 37 includes an L-shaped connecting block 371 fixedly mounted on the lower slider 35 and a fixing block 372 slidably mounted on the connecting block 371, used to clamp and fix the terminal 5 together with the receiving head 43 of the receiving mechanism during the insertion process. The connecting block 371 is fixed to the upper end of the lower slider 35 by bolts. Sliding grooves are provided on both sides of the upper end of the connecting block 371. The fixing block 372 is provided with a corresponding sliding part. In addition, a fixing part 373 protrudes from the end of the fixing block 372 near the receiving head 43. The fixing part 373 is a rectangular block structure with a width greater than or equal to that of the terminal 5 for better fixation.

[0063] Furthermore, a third damping element 374 acting on the fixed block 372 is provided on the connecting block 371. Preferably, the third damping element 374 is a spring 273. Intermediate blocks are fixedly installed at both ends of the connecting block 371. Spring 273 receiving holes are opened on both the intermediate blocks and the fixed block 372. The spring 273 is installed in the receiving holes of the two components. When the fixed block 372 contacts the terminal 5 and continues to move forward, the spring 273 is slowly compressed. Under the relative force, the fixed block 372 presses the terminal 5. In order to limit the sliding range of the fixed block 372, a limit port is opened on it, and a corresponding limit element is provided on the connecting block 371.

[0064] In addition, a fixing groove 375 is provided on the connecting block 371 at the position corresponding to the fixing part 373. The width of the fixing groove 375 is the same as that of the terminal 5. The fixing groove 375 can be pre-positioned into the terminal 5 before the terminal 5 is fixed by the fixing block 372, so that the terminal 5 can be fixed in the correct posture later.

[0065] When the fixing block 372 moves toward the connecting block 371 under the action of the third damping member 374, the fixing part 373 and the fixing groove 375 cooperate to clamp the terminal 5, thereby cooperating with the receiving head 43 to clamp the terminal 5 during the insertion process and realize the fixing of the terminal 5.

[0066] The receiving mechanism 4 is used to receive the cut terminals 5 and transport them to the insertion position. The receiving mechanism 4 includes a receiving cylinder 41 vertically fixedly mounted on the movable plate 33, a receiving slider 42 mounted on the output end of the receiving cylinder 41, and a receiving head 43 mounted on the upper end of the receiving slider 42. The piston rod of the receiving cylinder 41 is connected to the receiving slider 42 by a T-shaped member, which is embedded in the receiving slider 42 and its bottom is fixedly connected to the piston rod of the receiving cylinder 41. The receiving cylinder 41 is used to drive the receiving slider 42 and the receiving head 43 to rise and fall vertically to receive the terminals 5 cut by the cutting mechanism 2. The receiving head 43 is used to carry the terminals 5 cut by the cutting mechanism 2; under the joint clamping of the receiving head 43 and the terminal fixing assembly 37, the terminals 5 are driven by the first linear motion module 32 to drive the movable plate 33 to move, thereby completing the insertion action.

[0067] The receiving slider 42 has a slot 421 for accommodating the limiting head 363 to achieve vertical limiting. The receiving head 43 has a receiving part 431 that matches the shape of the terminal 5 for accurately carrying and positioning the terminal 5. The movable plate 33 is also equipped with a fourth support block 44 for supporting the sliding of the receiving slider 42, providing guidance and support for the lifting and lowering movement of the receiving slider 42. The fourth support block 44 also has a clearance opening at the slot 421, through which the limiting head 363 can pass.

[0068] like Figure 10 As shown, the present invention also provides an automatic cutting and insertion method for terminal 5, which uses the above-mentioned automatic cutting and insertion device for terminal 5 and includes the following steps:

[0069] S1. The starting device, the first linear motion module 32 drives the movable plate 33 and its components to move below the terminal 5, and then the receiving cylinder 41 drives the receiving slider 42 and the receiving head 43 to rise to near the terminal 5.

[0070] Specifically, the first linear motion module 32 drives the movable plate 33 and the receiving mechanism 4 and insertion mechanism 3 on it to move as a whole to the bottom of the cutting mechanism 2, so that the receiving head 43 is aligned with the terminal 5 to be cut, and the receiving cylinder 41 drives the receiving slider 42 and the receiving head 43 to rise to a position close to the terminal 5.

[0071] S2. The cutting cylinder 21 drives the connecting rod 22 to rotate and drives the upper slider 23 and the components on it to move down continuously. The positioning pin 272 first inserts into the positioning hole of the terminal strip, then the upper pressure block 271 presses the terminal strip, and finally the upper cutting blade 25 cuts the terminal 5 and places it on the receiving head 43.

[0072] Specifically, the piston rod of the cutting cylinder 21 extends, driving the connecting rod 22 to rotate, which in turn drives the upper slider 23 and the knife holder 27 to move downward. The positioning pin 272 first inserts into the positioning hole of the terminal strip to achieve precise positioning of the terminal 5. The upper pressure block 271 contacts and presses the terminal strip, and the spring 273 is compressed to provide elastic clamping force. The upper cutting blade 25 continues to move downward and cooperates with the lower cutting blade 26 to complete the cutting of the terminal 5. The cut terminal 5 falls on the receiving part 431 of the receiving head 43.

[0073] S3, receiving cylinder 41 drives receiving slider 42, receiving head 43 and its terminal 5 to move down a certain distance, and then clamping cylinder 34 drives lower slider 35 and its connecting block 371 and fixing block 372 to move close to terminal 5 to press terminal 5.

[0074] Specifically, receiving cylinder 41 drives receiving slider 42, receiving head 43 and terminal 5 on it to move down a certain distance, clamping cylinder 34 drives lower slider 35 to move towards receiving head 43, so that the fixing part 373 of terminal fixing assembly 37 cooperates with fixing groove 375 to clamp the bent section of terminal 5.
