Description

Technical Field

[0001] The utility model relates to the technical field of hardware terminal processing, and particularly relates to a high-precision PIN needle cutting device. Background Technique

[0002] A PIN needle is a metal substance used to complete the conduction (transmission) of electricity (signals) in a connector. Its main function is to complete the transmission of electricity and signals. A PIN needle cutting machine is a cutting device that cuts the PIN needles in a PIN needle strip into the same length.

[0003] According to a high-precision PIN needle cutting device disclosed in the patent publication number CN220092879U, it includes a machine body. A PIN needle cutting table is installed on the machine body, and a PIN needle strip conveying groove is opened on the PIN needle cutting table; a pressing and fixing component for pressing and fixing the PIN needles and the strip is further arranged above the PIN needle cutting table; a cutting knife extending into the PIN needle strip conveying groove and a pushing knife component connected to the cutting knife are also arranged on the machine body.

[0004] Although the above patent fixes the strip and the PIN needles through the pressing and fixing component, and then drives the cutting knife to move along the PIN needle strip conveying groove through the pushing knife component, the pins of multiple PIN needles on the strip can be continuously cut, improving the cutting efficiency, and the cutting position is constant, which can ensure that the cutting length of the pins is always the same, improving the cutting accuracy.

[0005] However, when the PIN needles are loaded into the PIN needle strip, the two ends of multiple PIN needles in the PIN needle strip are not necessarily all aligned. After the above technical solution clamps and fixes the strip and the upper ends of the PIN needles through the pressing and fixing component, and directly cuts from the fixed position by the cutting device, one end of the cut PIN needles is aligned, while the other end cannot be guaranteed to be all aligned. Therefore, the equal-length cutting effect of the PIN needles is not good. For this reason, we provide a high-precision PIN needle cutting device to solve this problem. Content of the Utility Model

[0006] The utility model aims to provide a technical solution of a high-precision PIN needle cutting device that can solve the above problems to overcome the above deficiencies.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A high-precision PIN needle cutting device, including a workbench, on the upper end of the workbench, a stop bar, a baffle, and a tape conveying concave plate are installed. On the upper end of the workbench, a side plate is installed. At the lower end of the side plate, a notch is provided. On the upper end of the workbench, a cutting mechanism and a material pushing mechanism are installed. One end of the material pushing mechanism penetrates through the side plate and extends to the outside thereof; the cutting mechanism includes a translation cylinder installed on the upper end of the workbench. A support seat is sleeved outside the output end of the translation cylinder. The upper end of the support seat is connected with a support plate. The support plate is located on the upper end of the side plate. On the upper end of the support plate, a lifting cylinder is installed. The output end of the lifting cylinder is screwed with a support frame. At the lower end of the support frame, a cutting knife is installed.

[0008] As a further scheme of the present utility model: The output end of the translation cylinder passes through the notch and is connected with a fixed frame. Inside the fixed frame, a guide inclined plate is connected. At the upper end of the guide inclined plate, a cutting groove is provided. The cutting groove corresponds to the position of the cutting knife.

[0009] As a further scheme of the present utility model: The lower end of the support plate is symmetrically and integrally connected with arc-shaped strips. On the upper end of the side plate, arc-shaped grooves are symmetrically provided for sliding connection therewith.

[0010] As a further scheme of the present utility model: On the upper end of the workbench, a waste material port is opened. In the middle of the inner cavity of the waste material port, a trapezoidal support block is connected.

[0011] As a further scheme of the present utility model: The material pushing mechanism includes two material pushing cylinders installed on the upper end of the workbench. The output ends of the material pushing cylinders are jointly connected with a connecting frame. On one side of the connecting frame, push columns are symmetrically connected. One end of the push columns penetrates through the side plate and is jointly connected with a fixing plate. On the outside of the fixing plate, material pushing components are equidistantly connected.

[0012] As a further scheme of the present utility model: The material pushing component includes an outer sleeve plate installed on the outside of the fixing plate. Inside the outer sleeve plate, two springs are installed. One ends of the two springs are jointly connected with a push plate. One end of the push plate penetrates through the outer sleeve plate and extends to the outside thereof. The material pushing component is located above the fixed frame.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The push plates of multiple pushing components in the pushing mechanism push the PIN pins loaded on the strip towards the baffle until they are in contact with it. Since the lengths of each PIN pin are different, when one end of a longer PIN pin is in contact with the baffle, the other PIN pins have not yet moved to the position of the baffle. Therefore, the longer PIN pin pushes the push plate in the reverse direction, and then the push plate compresses the spring and enters the inner cavity of the outer jacket plate until all the pushing components push the PIN pins to one end in contact with the baffle. After the ends of the PIN pins are aligned, and the PIN pins are effectively pushed and clamped, it is convenient for the cutting mechanism to perform stable cutting.

[0015] 2. The output end of the translation cylinder drives the fixed frame to move left and right, which is convenient for adjusting the distance between one end of the fixed frame and the PIN pins, and convenient for adjusting the position of the fixed frame according to the length to be cut, effectively improving the use effect. And when the position of the fixed frame is adjusted, during this process, the output end of the translation cylinder synchronously drives the support base, the support plate and the lifting cylinder to move. Finally, the output end of the lifting cylinder drives the support frame and the cutting knife to move downwards, so that the cutting knife synchronously cuts multiple groups of PIN pins, making the cut ends of the PIN pins also aligned, facilitating the same cutting length of the PIN pins and improving the cutting effect.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-9 , a high-precision PIN needle cutting device, including a workbench 1, on the upper end of the workbench 1, a retaining bar 2, a baffle 3 and a tape conveying concave plate 4 are installed. On the upper end of the workbench 1, a side plate 5 is installed. A notch 10 is arranged at the lower end of the side plate 5. On the upper end of the workbench 1, a cutting mechanism 6 is installed. One end of the material pushing mechanism 7 penetrates through the side plate 5 and extends to the outside thereof.

[0029] The cutting mechanism 6 includes a translation cylinder 61 installed on the upper end of the workbench 1. A support seat 62 is sleeved outside the output end of the translation cylinder 61. The upper end of the support seat 62 is connected with a support plate 63. The support plate 63 is located at the upper end of the side plate 5. On the upper end of the support plate 63, a lifting cylinder 65 is installed. The output end of the lifting cylinder 65 is screwed with a support frame 66. The lower end of the support frame 66 is installed with a cutting knife 67. The lower end of the support plate 63 is symmetrically and integrally connected with arc bars 64. Arc grooves 11 which are slidably connected with the arc bars 64 are symmetrically arranged at the upper end of the side plate 5.

[0030] The output end of the translation cylinder 61 passes through the notch 10 and is connected with a fixed frame 68. The inner side of the fixed frame 68 is connected with a guide chute 69. A cutting groove 610 is arranged at the upper end of the guide chute 69. The cutting groove 610 corresponds to the position of the cutting knife 67. A waste outlet 8 is opened on the upper end of the workbench 1. A trapezoidal support block 9 is connected to the middle part of the inner cavity of the waste outlet 8.

[0031] The output end of the translation cylinder 61 drives the fixed frame 68 to move left and right, facilitating the adjustment of the distance between one end of the fixed frame 68 and the stop bar 2. A tape conveying concave plate 4 is arranged on the right side of the stop bar 2, facilitating the movement and transportation of the tape inside the tape conveying concave plate 4, thereby adjusting the distance between the fixed frame 68 and the PIN pins loaded on the tape, facilitating the adjustment of the position of the fixed frame 68 according to the length to be cut, effectively improving the use effect. And when the position adjustment of the fixed frame 68 is completed, during this process, the output end of the translation cylinder 61 synchronously drives the support base 62, the support plate 63, and the lifting cylinder 65 to move synchronously. The arc-shaped strip 64 at the lower end of the support plate 63 slides stably in the inner cavity of the arc-shaped groove 11 at the upper end of the side plate 5, improving the movement stability of the support plate 63. Finally, the output end of the lifting cylinder 65 drives the support frame 66 and the cutting knife 67 to move downward, so that the cutting knife 67 synchronously cuts a plurality of groups of PIN pins until the lower end of the cutting knife 67 is inserted into the cutting groove 610 designed at the upper end of the material guiding inclined plate 69 to complete the cutting. The cut waste slides down from the material guiding inclined plate 69 and then falls from the middle of the fixed frame 68 into the waste outlet 8, and is centrally collected by an external collection box. And by arranging a trapezoidal support block 9 in the inner cavity of the waste outlet 8, it is convenient to increase the support stability of the fixed frame 68.

[0032] A material pushing mechanism 7 is installed on the upper end of the workbench 1. The material pushing mechanism 7 includes two material pushing cylinders 71 installed on the upper end of the workbench 1. The output ends of the material pushing cylinders 71 are commonly connected to a connecting frame 72. One side of the connecting frame 72 is symmetrically connected with material pushing columns 73. One end of the material pushing columns 73 penetrates through the side plate 5 and is commonly connected to a fixing plate 74. The outer side of the fixing plate 74 is equidistantly connected with material pushing components. The material pushing components include an outer jacket plate 75 installed on the outer side of the fixing plate 74. Two springs 76 are installed in the inner cavity of the outer jacket plate 75. One ends of the two springs 76 are commonly connected to a pushing plate 77. One end of the pushing plate 77 penetrates through the outer jacket plate 75 and extends to its outer side. The material pushing components are located above the fixed frame 68.

[0033] Before the cutting mechanism 6 performs cutting, the output end of the pushing cylinder 71 of the pushing mechanism 7 drives the connecting frame 72 and the pushing column 73 to move towards the direction of the strip and the PIN pins. Then, the pushing column 73 drives the fixing plate 74 and the pushing component to move and push the PIN pins clamped and loaded on the strip towards the direction of the baffle 3. Since the lengths of each PIN pin are different, multiple groups of pushing components are designed to separately push each PIN pin. When the pushing plate 77 of the pushing component moves to fit one end of the PIN pin, due to the continuous movement of the pushing column 73 driving the fixing plate 74 and the pushing component, the pushing plate 77 pushes the PIN pin until one end of it fits the baffle 3. For some PIN pins with longer lengths, when one end of the PIN pin fits the baffle 3, other PIN pins have not yet moved to the position of the baffle 3. Therefore, the longer PIN pins push the pushing plate 77 in the reverse direction. Then, the pushing plate 77 compresses the spring 76 and enters the inner cavity of the outer jacket plate 75 until all the pushing components push the PIN pins to make one end fit the baffle 3, facilitating the alignment of one end of the PIN pins, while the other ends have different lengths. After determining the length to be cut by the cutting mechanism 6, cutting is performed to make the other ends of the PIN pins aligned, facilitating the same cutting length of the PIN pins and improving the cutting effect.

[0034] Working principle: When the utility model is in use, it is controlled and connected to the translation cylinder 61, the lifting cylinder 65, and the pushing cylinder 71 through an external controller. During use, one end of the PIN needle tape is placed into the tape conveying concave plate 4, and it is driven to move and transport by an external transportation device. When a section of the PIN needle tape moves to the position of the pushing mechanism 7, the conveying of the PIN needle tape stops. The output end of the pushing cylinder 71 drives the connecting frame 72 and the pushing column 73 to move. Then, the pushing column 73 drives the fixing plate 74 and the pushing component to move. The push plate 77 of the pushing component pushes the PIN needles loaded on the tape towards the baffle 3 until they are in contact with it. Since the lengths of each PIN needle are different, and some PIN needles are longer, when one end of the PIN needle is in contact with the baffle 3, the other PIN needles have not yet moved to the position of the baffle 3. Therefore, the longer PIN needles push the push plate 77 in the reverse direction. Then, the push plate 77 compresses the spring 76 and enters the inner cavity of the outer jacket plate 75 until all the pushing components push the PIN needles to one end in contact with the baffle 3, facilitating the alignment of one end of the PIN needles, while the other ends are of different lengths. After determining the length to be cut through the cutting mechanism 6, that is, the output end of the translation cylinder 61 drives the fixed frame 68 to move left and right, facilitating the adjustment of the distance between one end of the fixed frame 68 and the PIN needles, and facilitating the adjustment of the position of the fixed frame 68 according to the length to be cut, effectively improving the use effect. And when the position of the fixed frame 68 is adjusted, during this process, the output end of the translation cylinder 61 synchronously drives the support seat 62, the support plate 63, and the lifting cylinder 65 to move synchronously. Finally, the output end of the lifting cylinder 65 drives the support frame 66 and the cutting knife 67 to move downward, so that the cutting knife 67 synchronously cuts a plurality of groups of PIN needles, making the other ends of the PIN needles aligned, facilitating the same cutting length of the PIN needles, and improving the cutting effect.
