DETAILED DESCRIPTION
[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Example 1
[0025] like Figures 1 to 5 As shown in the embodiment of this utility model, an electronic component insertion machine lead cutter includes a fixed base 1, a connecting bearing 2 fixedly connected to the middle of the fixed base 1, a connecting frame 3 fixedly connected to one side of the fixed base 1, a fixed shaft 4 fixedly connected to the top of the connecting frame 3, a fixed frame 5 fixedly connected to the middle of the fixed shaft 4, and a lead cutter assembly disposed inside the fixed frame 5. The lead cutter assembly includes a middle side blade 15 slidably connected inside the fixed frame 5. The bottom cross-section of the middle side blade 15 is concave, and the lead cutter assembly is symmetrically arranged.
[0026] Specifically, in the process of fixing and bending electronic components, existing electronic component insertion machines fix the electronic components individually and then bend them. However, after bending, because the two ends of the electronic component's leads are made of metal, they get stuck between the two bending blades and cannot be removed. When the next electronic component is being cut, it will cause wear and damage to the leads of the previous electronic component.
[0027] Therefore, this utility model solves this problem by setting up a corresponding structure. First, the fixed base 1 provides a stable support foundation, while the connecting frame 3 and the fixed shaft 4 ensure the stable installation of the fixed frame 5. The shearing component inside the fixed frame 5 presses and deforms the two pins of the electronic component. The middle side blade 15 is slidably connected inside the fixed frame 5. Its concave bottom design can more accurately fit the electronic component and abut against the two pins of the electronic component. The symmetrically arranged shearing components ensure the balance and efficiency of the shearing action. This design not only improves the stability and accuracy of the operation, but also effectively improves the work efficiency. At the same time, the sliding connection method also facilitates the maintenance and replacement of the middle side blade 15, enhancing the practicality and durability of the device.
[0028] like Figure 2 As shown, in this embodiment, an auxiliary frame 9 is fixedly connected to one side of the connecting frame 3, and an auxiliary plate 10 is fixedly connected to one side of the auxiliary frame 9. The auxiliary plates 10 are arranged symmetrically.
[0029] Specifically, by setting the auxiliary plate 10, the auxiliary plate 10 abuts against the middle side blade 15, so that the middle side blade 15 and its shearing foot assembly can slide stably along the auxiliary plate 10, thus achieving the effect of stabilizing the shearing foot.
[0030] like Figure 2As shown, the auxiliary plate 10 of the embodiment is provided with an auxiliary slot 11 near one end of the middle side knife 15.
[0031] Specifically, through the opening of the auxiliary slot 11, when the electronic component blank moves between the two auxiliary plates 10, it can be more fitted to the auxiliary plate 10, making the electronic component blank more stable, and at the same time, the auxiliary slot 11 can assist the middle side knife 15 in pressing, improving the pressing efficiency.
[0032] As shown, Figure 2 The connecting frame 3 of the embodiment is rotatably connected to a rotating shaft 7 on one side, and the one end of the rotating shaft 7 is fixedly connected to a limiting block 8, which is used to abut against the electronic component.
[0033] Specifically, the rotating shaft 7 can freely rotate on the connecting frame 3, driving the limiting block 8 fixedly connected to one end to move back and forth, and the limiting block 8 is used to abut against the electronic component accurately, achieving the effect of positioning the electronic component. Through the back-and-forth movement of the limiting block 8, the electronic component can be quickly positioned and fixed, improving the assembly efficiency and flexibility, and at the same time, the design of the limiting block 8 also ensures the stability and accuracy of the electronic component.
[0034] As shown, Figure 3 The two middle side knives 15 of the embodiment are each slidably connected to an inner side knife 12 on the side close to each other, and the two middle side knives 15 are each slidably connected to an outer side knife 16 on the side away from each other, and the limiting plate 6 is fixedly connected to the side of the fixed frame 5 corresponding to the middle side knife 15.
[0035] Specifically, first, the two pins of the electronic component are positioned by simultaneously moving the outer side knife 16 and the middle side knife 15 downward, and then the middle side knife 15 is driven to move downward by a certain distance. At this time, the middle side knife 15 is driven to move downward alone, which can make the two pins bend, thereby achieving the effect of pressing and folding. After pressing and folding, the innermost inner side knife 12 is driven alone to eject the electronic component stuck on the two auxiliary plates 10. At this time, the two auxiliary plates 10 will rotate downward by a certain angle, making the electronic component slide down and achieve the effects of automatic feeding, discharging and pin cutting.
[0036] As shown, Figure 3 The top ends of the two inner side knives 12 of the embodiment are fixedly connected to the same positioning shaft 13, and the middle side knives 15 are provided with positioning slots 14 corresponding to the positions of the positioning shaft 13.
[0037] Specifically, when the middle side knife 15 is pressed, the two pins after pressing will be stuck in the positioning slot 14 corresponding to the middle side knife 15, and the positioning slot 14 has the effect of limiting, and at the same time, the pressing and bending of the pin can be calibrated to prevent the pressing from being distorted, improving the pressing efficiency.
[0038] Working principle:

[0040] The middle knife 15 is connected in a sliding manner in the fixed frame 5, the concave bottom end design can more accurately fit the electronic component and abut against the two pins of the electronic component, and the balanced and efficient shearing action is ensured by the symmetrically arranged shear leg assemblies, this design not only improves the stability and accuracy of operation, but also effectively improves the work efficiency, at the same time, the sliding connection mode is convenient for maintaining and replacing the middle knife 15, and enhances the practicability and durability of the device;
[0041] In addition, when the middle knife 15 is pressed and assembled, the two pins after pressing and assembling are clamped in the positioning groove 14 opened in the corresponding middle knife 15, the positioning groove 14 has the effect of limiting, and the pressing and bending of the pins can be calibrated to prevent the pressing and twisting from occurring, thereby improving the pressing and assembling efficiency.
