[0021] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0022] like Figure 1-4 As shown: This embodiment provides an electronic component pin shearing and positioning device, including a processing seat 100 and a shearing mechanism, a slide groove 101 is opened in the middle of the processing seat 100, and two symmetrically arranged clamping plates 103 are slidably connected inside the slide groove 101, and a support seat 104 is fixedly connected to the top of the processing seat 100, and a rectangular opening penetrating the support seat 104 is opened in the middle of the support seat 104, and two symmetrically arranged bidirectional screw rods 105 are rotatably connected in the middle of the support seat 104, and a shearing mechanism is arranged between the two bidirectional screw rods 105, and the shearing mechanism includes a slider 201 and a cutter 202, and both ends of the bidirectional screw rod 105 are screwed The processing seat 100 is provided with a slider 201 connected with a groove, and a cutter 202 is fixedly connected between two adjacent sliders 201 located on different bidirectional screw rods 105, and the blades of the two cutters 202 are both facing the center of the processing seat 100. The bottom of the cutter 202 is fixedly connected with a plurality of clamping blocks 106, and the bottom of the clamping blocks 106 located on the same cutter 202 is provided with the same bottom plate 107, and both sides of the top of the bottom plate 107 are provided with limiting grooves, and the bottom of the clamping blocks 106 is slidably connected with the adjacent limiting grooves, and one end of the bottom plate 107 is provided with a clamping mechanism, and the clamping mechanism includes a top block 301, and the top block 301 is fixedly connected with one end of the bottom plate 107;

[0023] The components are introduced into the gap between the processing seat 100 and the support seat 104 so that the components are located at the top center of the processing seat 100. At this time, the pins of the components are placed in the center of the rectangular opening, and the tops of the pins of the components are higher than the support seat 104. Then, the clamping plates 103 on both sides are driven to move synchronously toward the center of the processing seat 100 to fix the components in the middle of the processing seat 100. After the components are stabilized, the two bidirectional screw rods 105 are synchronously rotated to make the shearing mechanism approach the middle of the bidirectional screw rods 105. The shearing mechanism drives the bottom plate 107 and the top block 301 to move synchronously so that the top block 301 fits tightly against the pins of the components, and the clamping plate 103 and the top block 301 work together to ensure that the components and the pins are in the correct position for cutting, thereby improving the accuracy of component positioning. The user continues to drive the cutting mechanism forward, so that the cutter 202 drives the clamping block 106 to slide in the bottom plate 107, so that the blade of the cutter 202 cuts out of the range of the bottom plate 107, and finally achieves synchronous contact between the cutters 202 on both sides and the pins to cut the pins, thereby reducing the cutting deviation caused by asymmetry during the cutting process, and further improving the accuracy and precision of the pin cutting.

[0024] Control switch group 108 as Figure 1 As shown,

[0025] A control switch group 108 is provided on one side of the processing seat 100, and an input end of the control switch group 108 is electrically connected to an external power supply;

[0026] The invention provides necessary control and power source for the shearing and positioning device of the pins of electronic components.

[0027] The first motor 109 is Figure 1 As shown,

[0028] A first motor 109 is fixedly connected to one side of the support base 104, and the output shaft of the first motor 109 is fixedly connected to one end of an adjacent bidirectional screw rod 105, and one end of the bidirectional screw rod 105 away from the first motor 109 is fixedly connected to a pulley 110, and the pulley 110 is connected through a belt transmission, and the input end of the first motor 109 is electrically connected to the output end of the control switch group 108;

[0029] The first motor 109 starts to operate after receiving the signal from the control switch group 108. When the motor is running, it will drive the bidirectional lead screw 105 to rotate. Due to the special thread design of the bidirectional lead screw 105, when the bidirectional lead screw 105 rotates, the two sliders 201 will move synchronously toward or away from each other along the direction of the bidirectional lead screw 105. When one lead screw rotates, the other lead screw will be driven to rotate synchronously through the belt. By adjusting the rotation direction and speed of the first motor 109, the moving speed and direction of the shearing mechanism can be controlled, thereby achieving precise shearing positioning of the pins of electronic components.

[0030] Bidirectional screw 111 Figure 2 As shown,

[0031] The middle of the slide 101 is rotatably connected with a bidirectional screw 111, the bottom of the clamping plate 103 is threadedly connected to the middle of the bidirectional screw 111, one side of the processing seat 100 is fixedly connected with a second motor 112, the output shaft of the second motor 112 is fixedly connected to one end of the bidirectional screw 111, and the input end of the second motor 112 is electrically connected to the output end of the control switch group 108;

[0032] The second motor 112 starts to operate after receiving the signal from the control switch group 108. When the second motor 112 is operating, it will drive the bidirectional screw 111 to rotate. The bidirectional screw 111 will drive the two clamps 103 to move synchronously toward or away from each other along the slide groove 101, which is used to fix and position electronic components. The operator can adjust the speed and direction of the second motor 112 by controlling the switch group 108, thereby accurately controlling the moving speed and position of the clamp 103.

[0033] Spring 302 Figure 3 As shown,

[0034] The clamping mechanism also includes a spring 302, and the top block 301 and the adjacent clamping plate are fixedly connected with the spring 302;

[0035] When it is necessary to cut the pins of electronic components, the clamping block 106 moves in the limiting groove toward the pins of the electronic components. During the process of cutting the pins, the spring 302 will be compressed. After the cutting is completed, the bottom plate 107 and the top block 301 are controlled to retract by controlling the switch group 108, and the spring 302 will return to its original state, so that the cutter 202 and the clamping block 106 return to the middle of the bottom plate 107 to avoid affecting the clamping of the pins by the top block 301.

[0036] Limiting plate 102 Figure 3 As shown,

[0037] One end of the bottom plate 107 away from the top block 301 is fixedly connected to the limiting plate 102;

[0038] This prevents the block 106 from bouncing off the bottom plate 107 when rebounding, thereby improving the working stability of the device.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0040] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
