Description

Technical Field

[0001] This utility model relates to the field of communication interface cutting technology, specifically a step-by-step cutting mechanism for communication interfaces. Background Technology

[0002] In the field of electronic equipment manufacturing, the cutting of communication interface tapes is a crucial step in the production process of communication interfaces. As electronic products continue to develop towards miniaturization, high performance, and high reliability, the requirements for the dimensional accuracy and pin quality of communication interfaces are becoming increasingly stringent.

[0003] Existing step-by-step cutting mechanisms for communication interfaces still have the following problems: Traditional cutting processes often use a single fixed tool for punching operations. Although the structure is simple and the manufacturing cost is low, this method lacks effective positioning and anti-shaking mechanisms when cutting communication interface tapes. This can easily lead to the tape shaking or shifting during the cutting process, resulting in large punching deviations and failing to ensure the cutting accuracy and flatness of the product. In addition, when cutting different parts of the communication interface, the previous process generally punched away all the waste material of the entire PD tape at once. Although the punching efficiency was high, the cutting force was concentrated in certain areas and could not be evenly distributed. This made the product prone to deformation and cracking, and the processing accuracy and quality were unstable, failing to meet the requirements for producing high-precision electronic products.

[0004] Therefore, there is an urgent need for a step-by-step cutting mechanism for communication interfaces to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a step-by-step cutting mechanism for a communication interface to solve the problems of material strip shaking or shifting and cutting force concentration during the cutting process.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a step-by-step cutting mechanism for a communication interface, comprising:

[0007] A feeding shell includes a shell, an opening, an upper punch, and a lower punch. Both ends of the shell are open, and the middle of the shell is a hollow feeding cavity. The opening is located on the side of the shell, extending to both ends of the shell. The upper punch and the lower punch are respectively located on opposite top and bottom surfaces of the feeding shell. One end of the upper punch extends to the wall of the hollow feeding cavity, and the other end extends to the lower punch and communicates with it. The open ends, the hollow feeding cavity, and the opening are interconnected. The feeding shell is used to carry a feeding belt, and the opening allows the pins of the product in the belt to pass through.

[0008] The first cutting assembly includes an upper pressure rod, a lower push rod, and a top block. The upper pressure rod and the lower push rod are respectively disposed at the top and bottom of the opening. Both the upper pressure rod and the lower push rod reciprocate clamping motion along the vertical direction of the pin. The center line of the upper pressure rod coincides with the center line of the lower push rod. The bottom surface of the upper pressure rod is used to cooperate with the top surface of the pin, and the lower push rod is used to cooperate with the bottom surface of the pin. The top block is disposed at the bottom of the opening. The top block reciprocates punching motion along the vertical direction of the pin. The upper pressure rod and the lower push rod are used to clamp the pin first, and the top block is used to punch the pin.

[0009] The second punching assembly includes a first push rod and a second push rod, both of which are disposed on the top surface of the feeding housing. The first push rod reciprocates vertically from the upper punching opening to the hollow feeding cavity, and the second push rod reciprocates vertically from the upper punching opening to the hollow feeding cavity and the lower punching opening in sequence. The first push rod is used to first clamp the material belt into the hollow feeding cavity, and the second push rod then punches the waste material out of the lower punching opening.

[0010] A preferred embodiment of the step-by-step cutting mechanism as a communication interface further includes a positioning component disposed on the housing, the positioning component being used to repeatedly fix the material strip.

[0011] As a preferred embodiment of a step-by-step cutting mechanism for a communication interface, the positioning component includes a needle body and a positioning hole. The positioning hole is installed on the housing and extends to the hollow feeding cavity. The needle body performs vertical reciprocating motion along the positioning hole. The needle body is used to pass through the positioning hole and cooperate with various mating holes on the conveyor belt in the hollow feeding cavity.

[0012] A preferred embodiment of a step-by-step cutting mechanism for a communication interface further includes a first driving component disposed on the housing, the first driving component driving the top block to perform a reciprocating punching motion along the vertical direction of the pin.

[0013] As a preferred embodiment of a step-by-step cutting mechanism for a communication interface, the first driving component includes a driving element, a guide rail, and a guide block. The guide rail and the driving element are both fixed on the housing. The guide block is slidably disposed on the guide rail. The top block is mounted on the guide block. The driving end of the driving element drives the guide block and the top block to perform reciprocating punching motion along the vertical direction of the pin.

[0014] As a preferred embodiment of a step-by-step cutting mechanism for a communication interface, the top block is provided with a perforation hole, the edge of which is used for punching pins, and the hole body of which is used for transporting waste material.

[0015] A preferred embodiment of the step-by-step cutting mechanism for a communication interface further includes a shock-absorbing component disposed on the housing, the shock-absorbing component being used for shock absorption of the upper pressure rod and the first push rod.

[0016] As a preferred embodiment of a step-by-step cutting mechanism for a communication interface, the shock-absorbing component includes an elastic element and a slider. The slider reciprocates vertically along the housing. The upper pressure rod is slidably mounted on the slider. The elastic element is installed on the slider, with one end fixedly connected to the slider and the other end fixedly connected to the upper pressure rod. The upper pressure rod moves vertically downward with the slider and presses against the upper end face of the material strip, compressing the elastic element. The slider continues to move downward until the upper pressure rod compacts the elastic element and tightens the material strip.

[0017] A preferred embodiment of the step-by-step cutting mechanism as a communication interface further includes a traction component disposed on the housing, the traction component being used to traction the material strip.

[0018] As a preferred embodiment of a step-by-step cutting mechanism for a communication interface, the traction assembly includes a slot, a rotating wheel, and a mating block. The slot is disposed on the housing, the rotating wheel is movably connected to the side of the housing and rotates into the slot, and the mating block is circumferentially disposed on the circumferential edge of the rotating wheel and is used to fit into various mating holes on the conveyor belt.

[0019] The beneficial effects of this invention are as follows: By using the coordinated operation of the upper pressure rod, lower push rod, and top block in the first cutting component, punching deviations caused by pin wobbling or offset are effectively avoided, ensuring the accuracy, flatness, and stability of pin cutting. The second cutting component, with its first and second push rods, further effectively avoids punching deviations caused by product wobbling or offset. Through the cooperation of the first and second cutting components, step-by-step, orderly cutting operations on different parts of the communication interface are achieved. This also effectively disperses and balances cutting stress, ensuring the accuracy and quality stability of each part of the product processing. This allows the product to be transferred to the next process with high-precision specifications, thus ensuring the continuity and accuracy of the entire communication interface cutting process and improving overall production efficiency.

[0034] In one embodiment of this utility model, such as Figure 1-8As shown, a step-by-step cutting mechanism for a communication interface is provided, including: a feeding shell 1, a first cutting component 2, and a second punching component 3. The feeding shell 1 includes a housing 11, an opening 12, an upper punching notch 13, and a lower punching notch 14. Both ends of the housing 11 are open, and the middle of the housing 11 is a hollow feeding cavity. The opening 12 is located on the side of the housing 11, and both ends of the opening 12 extend to both ends of the housing 11. The upper punching notch 13 and the lower punching notch 14 are respectively located on the opposite top and bottom surfaces of the feeding shell 1. One end of the upper punching notch 13 extends to the cavity wall of the hollow feeding cavity. The other end of the cut 13 extends to the lower punch cut 14 and is connected to the lower punch cut 14. The open end, the hollow feeding chamber, and the opening 12 are interconnected. The feeding shell 1 is used to carry the feeding belt, and the opening 12 is used for the pins of the product in the belt to pass through. The first cutting assembly 2 includes an upper pressure rod 21, a lower push rod 22, and a top block 23. The upper pressure rod 21 and the lower push rod 22 are respectively located at the top and bottom of the opening 12. The upper pressure rod 21 and the lower push rod 22 are both along the pins. The upper pressure rod 21 and the lower push rod 22 reciprocate in a vertical clamping motion. The center line of the upper pressure rod 21 coincides with the center line of the lower push rod 22. The bottom surface of the upper pressure rod 21 is used to cooperate with the top surface of the pin, and the lower push rod 22 is used to cooperate with the bottom surface of the pin. The top block 23 is set at the bottom of the opening 12. The top block 23 reciprocates in a punching motion along the vertical direction of the pin. The upper pressure rod 21 and the lower push rod 22 are used to clamp the pin first, and the top block 23 is used to punch the pin. The second punching assembly 3 includes a first push rod 31 and a second push rod 32. The first push rod 31 and the second push rod 32 are both set on the top surface of the feeding shell 1. The first push rod 31 reciprocates vertically from the upper punching opening 13 to the hollow feeding cavity. The second push rod 32 reciprocates vertically from the upper punching opening 13 to the hollow feeding cavity and the lower punching opening 14 in sequence. The first push rod 31 is used to clamp the material into the hollow feeding cavity first, and the second push rod 32 punches the waste material out of the lower punching opening 14.

[0035] The step-by-step cutting mechanism of the communication interface provided in this embodiment uses the first cutting component 2 to set up the coordinated operation of the upper pressure rod 21, the lower push rod 22 and the top block 23. The upper pressure rod 21 and the lower push rod 22 clamp the pin, and the top block 23 performs the punching, realizing the operation of clamping first and then punching. This effectively avoids the punching deviation caused by pin shaking or offset, and effectively ensures the accuracy, flatness and stability of pin cutting.

[0036] The second cutting assembly uses a first push rod 31 to clamp the material into the hollow feeding cavity, and a second push rod 32 to punch the waste material out of the lower punch 14. The first push rod 31 can vertically fix the material in the hollow feeding cavity, ensuring that the material is in a suitable position for processing within the cavity. The second push rod 32 can further penetrate and punch the waste material into the lower punch 14, effectively avoiding punching deviations caused by product shaking or offset. Combined with the first cutting assembly 2, this achieves step-by-step, orderly cutting operations on different parts of the communication interface, effectively dispersing and balancing cutting stress, ensuring the accuracy and quality stability of each part of the product processing, and enabling it to flow to the next process with high-precision product specifications. This ensures the continuity and accuracy of the entire communication interface cutting process, improving overall production efficiency.

[0037] Preferably, the center line of the upper pressure rod 21 coincides with the center line of the lower push rod 22 to improve the accuracy of pressing the product pins.

[0038] Preferably, the housing 11 is provided with a vertical drive assembly 8 on its side for driving the upper pressure rod 21, the first push rod 31 and the second push rod 32. The vertical drive assembly 8 drives the upper pressure rod 21 to reciprocate along the vertical direction of the pin, drives the first push rod 31 to reciprocate vertically from the upper punch cutout 13 to the hollow feeding cavity, and drives the second push rod 32 to reciprocate vertically from the upper punch cutout 13 to the hollow feeding cavity and the lower punch cutout 14 in sequence.

[0039] Specifically, the vertical drive assembly 8 includes a support frame 81, a first vertical drive source 82, and a sliding block 83. The first vertical drive source 82 can be a cylinder. The support frame 81 is fixedly erected on the housing 11. The first vertical drive source 82 is fixed to the side of the support frame 81. The sliding block 83 is slidably disposed on the opposite side of the support frame 81 where the first vertical drive source 82 is mounted. The sliding block 83 is connected to the vertical extension end of the first vertical drive source 82. The slider 62 is fixed on the sliding block 83. Preferably, the lower push rod 22 can also perform vertical reciprocating motion through the first vertical drive source 82 in conjunction with the upper pressure rod 21.

[0040] Preferably, the side of the support plate frame 81 where the sliding block 83 is mounted is provided with a sliding groove, and the side of the sliding block 83 is provided with a step for guiding the sliding with the sliding groove. The cooperation of the sliding groove and the step guides the sliding block 83 to slide more stably, thereby improving the stability and accuracy of the punching.

[0041] Preferably, two vertical drive assemblies 8 can be installed depending on the installation configuration of the upper pressure rod 21, the first push rod 31, and the second push rod 32. Correspondingly, there are also two sliders 62, one for mounting the upper pressure rod 21 and the other for mounting the first push rod 31 and the second push rod 32. Of course, in other embodiments, the number of vertical drive assemblies 8 can also be more than two.

[0042] The motion process in the step-by-step cutting mechanism of the communication interface provided in this embodiment is as follows: drive one of the vertical drive components 8 to drive the slider 62 on the sliding block 83, thereby driving the upper pressure rod 21 to reciprocate along the vertical direction of the pin; drive the other vertical drive component 8 to drive the slider 62 on the sliding block 83, thereby driving the first push rod 31 and the second push rod 32 to reciprocate along the vertical direction of the material strip.

[0043] The step-by-step cutting mechanism of this communication interface also includes a shock-absorbing component 6, which is mounted on the housing 11. The shock-absorbing component 6 is used to dampen the upper pressure rod 21 and the first push rod 31. Through the shock-absorbing component 6, the impact force generated during the cutting process can be effectively absorbed and buffered, ensuring the stability of the cutting.

[0044] Preferably, the shock-absorbing assembly 6 includes an elastic element 61 and a slider 62. The elastic element 61 can be made of a spring. The slider 62 reciprocates vertically along the housing 11. The upper pressure rod 21 is slidably mounted on the slider 62. The elastic element 61 is mounted on the slider 62. One end of the elastic element 61 is fixedly connected to the slider 62, and the other end of the elastic element 61 is fixedly connected to the upper pressure rod 21. The upper pressure rod 21 moves vertically downward with the slider 62. The upper pressure rod 21 presses against the upper end face of the material strip, compressing the elastic element 61. The slider 62 continues to move downward until the upper pressure rod 21 compresses the elastic element 61 and tightens the material strip.

[0045] Preferably, the slider 62 includes a block 621 and a baffle 622. A through hole is formed in the block 621. The baffle 622 is erected on top of the upper pressure rod 21, with a movable gap between the upper end of the baffle 622 and the top surface of the block 621. The two ends of the spring are positioned at the upper end of the baffle 622 and the top of the through hole. Specifically, when installing the upper pressure rod 21, it is installed in the through hole and fixedly connected to the spring. When installing the first push rod 31, it is installed in the through hole and fixedly connected to the spring. Specifically, the second push rod 32 is fixed to the side of the block 621.

[0046] Based on the bottom surface of block 621, the length of the first push rod 31 extending through the bottom surface of block 621 is longer than the length of the second push rod 32 extending through the bottom surface of block 621, ensuring that the first push rod 31 first enters the upper punch cut 13 into the hollow feeding cavity and then contacts and fixes the material strip. As block 621 continues to descend, the second push rod 32 enters the upper punch cut 13 into the hollow feeding cavity and then punches the material strip. At this time, the waste material can fall from the inner wall of the hollow feeding cavity out of the lower punch cut 14.

[0047] Preferably, the bottom surface of the block 621 is provided with a punch 80, and the top surface of the housing 11 is provided with a punch 90 for the punch 80 to penetrate into the hollow feeding cavity. When the block 621 moves vertically, the punch 80 can penetrate into the punch 90 into the hollow feeding cavity and cooperate with the mating hole 10 of the material strip. This can effectively avoid problems such as material strip deviation and deformation during processing, ensure the high fit and connection stability of each component during subsequent assembly, and effectively improve the overall structural accuracy and performance reliability of the product.

[0048] The step-by-step cutting mechanism of the communication interface also includes a first driving component 5, which is disposed on the housing 11. The first driving component 5 drives the top block 23 to perform reciprocating cutting motion along the vertical direction of the pin. The first driving component 5 includes a driving element 51, a guide rail 52, and a guide block 53. The driving element 51 can be composed of a cylinder. The guide rail 52 and the driving element 51 are both fixed on the housing 11. The guide block 53 is slidably disposed on the guide rail 52. The top block 23 is disposed on the guide block 53. The driving end of the driving element 51 drives the guide block 53 and the top block 23 to perform reciprocating cutting motion along the direction of the guide rail 52. That is, the driving end of the driving element 51 drives the guide block 53 and the driving element 51 to perform reciprocating cutting motion along the vertical direction of the pin.

[0049] Preferably, the top block 23 is provided with a protective plate 30 at its upper end, and there is a gap between the top block 23 and the protective plate 30. The gap allows the pins to pass through and the protective plate 30 to block the splashed waste, thereby improving the safety of the step-by-step cutting mechanism using the communication interface in the cooperating mechanism.

[0050] Preferably, the top block 23 is provided with a hole 20, the edge of the hole 20 is used for punching leads, the hole of the hole 20 is used for transporting waste material, and a feeding rack 40 can be installed under the hole 20 and under the lower punching opening 14 respectively. The waste material on the hole 20 can fall into the feeding rack 40, which is convenient for centralized processing of waste material later.

[0051] The step-by-step cutting mechanism of this communication interface also includes a positioning component 4, which is mounted on the housing 11. The positioning component 4 is used to repeatedly fix the material strip. Specifically, the positioning component 4 includes a needle body 41 and a positioning hole 42. The positioning hole 42 is installed on the housing 11, and the depth of the positioning hole 42 extends into the hollow feeding cavity. A cylinder and a connecting block can be installed on the housing 11 to realize the vertical reciprocating movement of the needle body 41 along the positioning hole 42. The needle body 41 is used to pass through the positioning hole 42 and cooperate with the various mating holes 10 on the transport material strip in the hollow feeding cavity. This further prevents the material strip from shifting or deforming during processing, allowing subsequent component assembly to fit precisely and connect firmly, improving the product's structural accuracy and performance, and ensuring product quality.

[0052] The step-by-step cutting mechanism of the communication interface also includes a traction component 7, which is mounted on the housing 11 and is used to pull the conveyor belt. Specifically, the traction component 7 includes a slot 71, a rotating wheel 72, and a mating block 73. The slot 71 is mounted on the housing 11. The rotating wheel 72 is movably connected to the side of the housing 11 for rotational movement. Specifically, a motor can be mounted on the housing 11 to drive the rotating wheel 72 to rotate. The rotating wheel 72 rotates into the slot 71, and the mating block 73 is circumferentially disposed on the circumferential edge of the rotating wheel 72. The mating block 73 is used to fit into the various mating holes 10 on the conveyor belt. The motor drives the rotating wheel 72 to rotate stably within the slot 71, and the mating block 73 is tightly engaged with the mating hole 10 on the material strip. This allows the material strip to be transmitted accurately and smoothly at the set speed and direction under the action of the traction component 7. This effectively avoids abnormal situations such as jamming, slippage or deviation of the material strip during the traction process, ensuring that the material strip conveying link in the entire cutting process is efficient and reliable. This provides a strong guarantee for the subsequent step-by-step cutting process and improves the continuity and stability of the overall production.

[0053] The process of traction material strip in the step-by-step cutting mechanism of the communication interface provided in this embodiment is as follows: drive motor, the motor drives the rotating wheel 72 to rotate, and the mating block 73 on the rotating wheel 72 engages with each mating hole 10 on the material strip.
