[0041] The two lifting seats 108 are slidably connected to the two sliding seats 112 in a one-to-one correspondence, and the sliding direction of the lifting seats 108 is consistent with the axial direction of the lifting shaft 119, so that the lifting shaft 119 can drive the lifting seats 108 to stably lift and slide.
[0042] The two sliding seats 112 are slidably connected to the fixed seat 101 along the radial direction of the lifting shaft 119, and the two sliding seats 112 are respectively transmission connected to the rod segments of the bidirectional screw 111 with different rotation directions, so that the bidirectional screw 111 can drive the two sliding seats 112 to approach or move away from each other, so that the shear pin detection mechanism can perform highly compatible shear pin processing on electronic components with different pin distances.
[0043] Please refer to Figure 3 and Figure 4 The lifting follower block 121 is fixedly connected to one end of the lifting shaft 119.

[0048] The foot-cutting follower block 122 is fixedly connected to one end of the control shaft 120. The movable foot-cutting tool body 109 is rotatably connected to the lifting seat 108. The linkage rod 123 is slidably arranged in the lifting seat 108. One end of the linkage rod 123 contacts the foot-cutting follower block 122, and the other end of the linkage rod 123 is drivingly connected to the movable foot-cutting tool body 109 through a transfer rod 124. Thus, the control shaft 120 can drive the movable foot-cutting tool body 109 to rotate for foot-cutting work.
[0049] One end of the foot-cutting spring 127 is connected to the linkage rod 123, and the other end of the foot-cutting spring 127 is connected to the lifting seat 108. The foot-cutting spring 127 is used to pull the linkage rod 123 to keep contacting the foot-cutting follower block 122, so that the control shaft 120 can stably and synchronously drive the movable foot-cutting tool body 109 to rotate.
[0050] Specifically, the lifting seat 108 is provided with an avoidance groove for accommodating the foot-cutting spring 127. A first connecting rod 125 is arranged on one side of the linkage rod 123, and the first connecting rod 125 is located in the avoidance groove. A second connecting rod 126 is arranged on the inner wall of the avoidance groove. Two ends of the foot-cutting spring 127 are respectively connected to the first connecting rod 125 and the second connecting rod 126. In addition, a pressure wheel 1231 for contacting the foot-cutting follower block 122 is arranged at one end of the linkage rod 123.
[0051] Please refer to Figure 2 , in this embodiment, a lifting connection ring body 115 is fixedly arranged on the lifting shaft 119. A lifting connection groove is arranged along the circumference of the lifting connection ring body 115. Two lifting transmission columns 1051 are oppositely arranged at one end of the lifting connecting rod 105, and the two lifting transmission columns 1051 are respectively slidably inserted into opposite sides in the lifting connection groove. It is convenient for the lifting connecting rod 105 and the lifting connection ring body 115 to be assembled in cooperation, and the transmission is stable.
[0052] A foot-cutting connection ring body 116 is fixedly arranged on the control shaft 120. A foot-cutting connection groove is arranged along the circumference of the foot-cutting connection ring body 116. Two foot-cutting transmission columns 1061 are oppositely arranged at one end of the foot-cutting connecting rod 106, and the two foot-cutting transmission columns 1061 are respectively slidably inserted into opposite sides in the foot-cutting connection groove. It is convenient for the foot-cutting connecting rod 106 and the foot-cutting connection ring body 116 to be assembled in cooperation, and the transmission is stable.
[0053] Please refer to Figure 1 and Figure 2, in this embodiment, the lifting link 105 and the leg-shearing link 106 extend on opposite sides of the output shaft of the motor 102 respectively. The leg-shearing detection mechanism of the horizontal combined plug-in machine is installed on the mounting frame. The lifting link 105 is connected to the mounting frame through the first tension spring 1141, and the first tension spring 1141 is used to pull the lifting link 105 to keep it in contact with the leg-shearing lifting cam 103. The leg-shearing link 106 is connected to the mounting frame through the second tension spring 1142, and the second tension spring 1142 is used to pull the leg-shearing link 106 to keep it in contact with the leg-shearing control cam 104.
[0054] Please refer to Figure 2 , more specifically, the leg-shearing lifting cam 103 includes a return-position arc side and a working-position arc side on the circumference. The radius of the return-position arc side is greater than that of the working-position arc side. When the return-position arc side contacts the lifting link 105, it will cause the lifting shaft 119 to move away from the electronic component.
[0055] The leg-shearing control cam 104 includes a leg-shearing position arc side and a standby position arc side on the circumference. The radius of the leg-shearing position arc side is greater than that of the standby position arc side. When the leg-shearing position arc side contacts the leg-shearing link 106, it will cause the control shaft 120 to move towards the electronic component, and then drive the movable leg-shearing blade body 109 to rotate close to the fixed leg-shearing blade body 110 for leg-shearing work.
[0056] Among them, when the lifting link 105 contacts the return-position arc side, the leg-shearing link 106 contacts the standby position arc side, and at this time it is in a state away from the electronic component. When the lifting link 105 contacts the working-position arc side, the leg-shearing link 106 contacts the leg-shearing position arc side, and at this time it is in a state close to the electronic component and performing leg-shearing operation.
[0057] Please refer to Figure 2 , specifically, one end of the lifting link 105 is provided with a first roller 1052 for contacting the leg-shearing lifting cam 103 to improve the smoothness of the leg-shearing lifting cam 103 driving the lifting link 105. One end of the leg-shearing link 106 is provided with a second roller 1062 for contacting the leg-shearing control cam 104 to improve the smoothness of the leg-shearing control cam 104 driving the leg-shearing link 106.
[0058] Please refer to Figure 6 , the leg-shearing detection mechanism of the horizontal combined plug-in machine in this embodiment further includes a detection rod 130. The detection rod 130 is arranged at the shearing end of the movable leg-shearing blade body 109. One end of the detection rod 130 is used to cooperate with the fixed leg-shearing blade body 110 to shear the pins of the electronic component, and the other end of the detection rod 130 is connected to the corresponding detection device through a lead wire. While shearing the legs of the electronic component, corresponding detection can be carried out, such as performing pressure-sensitive detection, with high working efficiency.
[0059] Please refer to Figure 3 and Figure 6 In this embodiment, the fixed pin-cutting knife body 110 includes a pin-cutting groove 128. On two adjacent sides of the pin-cutting groove 128, a pin-cutting opening 1101 and a working opening 1102 are respectively arranged. The pin-cutting opening 1101 is located on the side of the pin-cutting groove 128 facing away from the lifting seat 108, and the working opening 1102 is for the detection rod 130 to enter the pin-cutting groove 128. One end of the detection rod 130 is convexly provided with a bending block 1301 on the side close to the pin-cutting groove 128. The bending block 1301 is arranged in a dislocation manner with the surface of the fixed pin-cutting knife body 110 facing away from the lifting seat 108. The pins of the electronic component are cut off in the pin-cutting groove 128 by the dislocation shearing between the bending block 1301 and the surface of the fixed pin-cutting knife body 110 facing away from the lifting seat 108.
[0060] Furthermore, the pin-cutting detection mechanism of the horizontal combined plug-in machine further includes a waste suction pipe 129. The waste suction pipe 129 is communicated with the inner cavity of the pin-cutting groove 128. The waste suction pipe 129 is connected to a suction device. A ventilation filter screen can also be arranged between the waste suction pipe 129 and the suction device. In this way, the waste suction pipe 129 can suck the pin-cutting waste into the ventilation filter screen, similar to the structure of a vacuum cleaner.
[0061] Working principle of the present invention: When cutting the pins of an electronic component, the motor 102 works to drive the pin-cutting lifting cam 103 and the pin-cutting control cam 104 to rotate.
[0062] When the working position arc side of the pin-cutting lifting cam 103 starts to contact the lifting connecting rod 105, the pin-cutting position arc side of the pin-cutting control cam 104 gradually contacts the pin-cutting connecting rod 106.
[0063] Under the pulling of the first tension spring 1141, the lifting connecting rod 105 makes the control shaft 120 move towards the direction close to the electronic component, and drives the lifting seat 108 to move towards the direction close to the electronic component, so that the pins of the electronic component extend from the pin-cutting opening 1101 into the pin-cutting groove 128. Under the extrusion of the pin-cutting control cam 104, the pin-cutting connecting rod 106 will drive the control shaft 120 to move towards the direction close to the electronic component, and then drive the movable pin-cutting knife body 109 to rotate close to the fixed pin-cutting knife body 110, and cut off the pins of the electronic component in the pin-cutting groove 128. Then, the waste suction pipe 129 sucks away the pin waste in the pin-cutting groove 128.
[0064] In this way, the pin-cutting detection process of the pin-cutting detection mechanism of the horizontal combined plug-in machine in this embodiment is completed.
[0065] The following is the second embodiment of the leg cutting detection mechanism of a horizontal combined plug-in machine provided by the present invention, which can solve the above technical problems. The main difference between this embodiment and the first embodiment is that an adjustment mechanism for adjusting the first roller is provided on the lifting link. By adjusting the position of the first roller relative to the lifting link, the distance that the leg cutting lifting cam drives the lifting axis to move away from the electronic component is changed, thereby changing the leg cutting length of the electronic component. The structures that are the same as those in the first embodiment in this embodiment will not be described in detail.
[0066] The leg cutting detection mechanism of the horizontal combined plug-in machine in this embodiment can meet different leg cutting requirements by setting an adjustment mechanism for adjusting the first roller, and can further solve the problems of low compatibility of the leg cutting equipment in the prior art for leg cutting processing of electronic components and low efficiency in processing products with different batches and different processing requirements.
[0067] Please refer to Figure 7 and Figure 8 , in this embodiment, a receiving groove for installing the first roller 1052 is provided on the lifting link 105, and the first roller 1052 passes through the receiving groove and contacts the leg cutting lifting cam 103. Rotating shafts 21 are provided on both sides of the first roller 1052, and long strip grooves 22 communicating with the receiving groove are provided on both sides of the lifting link 105. The rotating shafts 21 form a sliding and rotating fit with the long strip grooves 22, and the sliding trajectory of the rotating shafts 21 is perpendicular to the axial direction of the leg cutting lifting cam 103. A fixing hole 23 communicating with the long strip groove 22 is provided on the surface of the lifting link 105 facing away from the leg cutting lifting cam 103.
[0068] A fixing plate 24 is provided on the surface of the lifting link 105 facing away from the leg cutting lifting cam 103. A movable plate 25 is provided on the surface of the fixing plate 24 facing away from the leg cutting lifting cam 103. A set distance is provided between the movable plate 25 and the fixing plate 24. A screw 26 passes through the movable plate 25 and is threadedly connected to the fixing plate 24. Extrusion rods 251 are provided at both ends of the movable plate 25. The extrusion rods 251 are slidably connected in the fixing hole 23 and contact the rotating shafts 21. At the same time, since the first tension spring 1141 will pull the lifting link 105 to rotate towards the direction close to the leg cutting lifting cam 103, the first roller 1052 is always in contact with the leg cutting lifting cam 103, and at the same time, the rotating shafts 21 are always in contact with the extrusion rods 251. In this way, by screwing the screw 26, the length of the extrusion rod 251 extending into the fixing hole 23 can be adjusted, so as to adjust the position of the first roller 1052 relative to the lifting link 105.
[0069] As Figure 7 , Figure 7The middle extrusion rod 251 and the fixing hole 23 are in a disassembled state. When the length of the extrusion rod 251 extending into the fixing hole 23 is longer, the distance that the first roller 1052 protrudes from the surface of the lifting link 105 towards the trimming lift cam 103 is greater. In this way, the trimming lift cam 103 can drive the lifting shaft 119 to move a greater distance, and the length of the pins cut off by the movable trimming blade body 109 and the fixed trimming blade body 110 is longer.
[0070] When the length of the extrusion rod 251 extending into the fixing hole 23 is shorter, the distance that the first roller 1052 protrudes from the surface of the lifting link 105 towards the trimming lift cam 103 is smaller. In this way, the distance that the trimming lift cam 103 drives the lifting shaft 119 to move is smaller, and the length of the pins cut off by the movable trimming blade body 109 and the fixed trimming blade body 110 is shorter.
[0071] Please refer to Figure 8 , furthermore, a limiting ring body 27 is provided on the surface of the movable plate 25 facing away from the trimming lift cam 103. The screw 26 is located inside the limiting ring body 27. Two operating plates 28 are elastically slidably arranged on both sides of the screw 26 along the radial direction, and the plate surfaces of the operating plates 28 are parallel to the radial plane of the screw 26. Specifically, a spring can be arranged between the two operating plates 28 to achieve the sliding arrangement of the two operating plates 28.
[0072] A plurality of scale grooves 271 are arranged along the inner circumference on the inner wall of the limiting ring body 27. The sliding trajectory of the operating plate 28 includes a limiting position limited to the scale grooves 271 and a movable position avoiding the scale grooves 271. Among them Figure 8 is a schematic diagram, and the component dimensions and the number of scale grooves 271 in the figure are not used to limit the present invention.
[0073] Lugs 281 for easy holding and operation can be arranged on the outer sides of the operating plates 28. By pinching the lugs 281 of the two operating plates 28, the two operating plates 28 can be slid towards each other to the movable position, so that the screw 26 can be rotated to adjust the extrusion dimension of the extrusion rod 251 on the rotating shaft 21. When the two operating plates 28 are released, the spring pushes the two operating plates 28 away from each other, and the operating plates 28 are clamped into the scale grooves 271. The cooperation between the operating plates 28 and the scale grooves 271 can not only prevent the screw 26 from loosening, but also feedback the rotation adjustment angle of the screw 26. The structure is stable and the operation is convenient.
[0074] In the trimming detection mechanism of the horizontal combined plug-in machine of the present invention, by sliding the control shaft through the inside of the lifting shaft, the motor can drive the control shaft and the lifting shaft to move simultaneously, so as to move the movable trimming blade body and the fixed trimming blade body towards the electronic component and realize the trimming operation, with low cost and small volume.
[0075] In addition, the movable leg-cutting knife body and the fixed leg-cutting knife body are driven by a first tension spring to pull the lifting connecting rod to move in the direction close to the electronic component, so that the movable leg-cutting knife body and the fixed leg-cutting knife body elastically and flexibly approach and contact the pins of the electronic component, and then the leg-cutting control cam squeezes the leg-cutting connecting rod, so that the movable leg-cutting knife body and the fixed leg-cutting knife body strongly cut the pins of the electronic component, with little impact damage to the electronic component and good cutting effect.
[0076] In summary, although the present invention has been disclosed above with the preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
