[0043] Please refer to Figures 1 to 3 In the figures, units with similar structures are represented by the same reference numerals.

[0044] This embodiment provides a shear foot detection mechanism for a horizontal connected plug-in machine, which includes: a fixed seat 101, a motor 102, a shear foot lifting cam 103, a shear foot control cam 104, a lifting connecting rod 105, a shear foot connecting rod 106, a lifting shaft 119, a control shaft 120, a lifting seat 108, a movable shear foot blade body 109, and a fixed shear foot blade body 110.

[0045] The lifting shaft 119 is slidably connected to the fixed base 101, and the control shaft 120 slides through the interior of the lifting shaft 119. A sleeve member 107 can be fixedly set through the fixed base 101, and then the lifting shaft 119 is slidably set in the sleeve member 107, which can improve the stability of the lifting shaft 119 in sliding and lifting.

[0046] The lifting seat 108 is connected to one end of the lifting shaft 119, and the lifting shaft 119 is used to drive the lifting seat 108 to move up and down. The fixed shearing blade body 110 is fixedly set at the end of the lifting seat 108 away from the lifting shaft 119, and the movable shearing blade body 109 is movably set in the lifting seat 108. The two ends of the movable shearing blade body 109 are respectively a cutting end and a control end. The cutting end is staggered with the fixed shearing blade body 110, and the control end is connected to the control shaft 120. The control shaft 120 is used to drive the movable shearing blade body 109 to move, so that the cutting end and the fixed shearing blade body 110 move relative to each other to cut the pins of the electronic components.

[0047] Please refer to Figure 1 and Figure 2 In this embodiment, the motor 102 is fixedly connected to the fixing base 101. The shearing foot lifting cam 103 and the shearing foot control cam 104 are both connected to the output shaft of the motor 102. The shearing foot lifting cam 103 and the shearing foot control cam 104 can be connected to the output shaft of the motor 102 via components such as a rotating shaft, a coupling, and a transmission structure.

[0048] The lifting link 105 and the shear foot link 106 are both rotatably connected to the fixed base 101, the lifting shaft 119 is transmission-connected to the shear foot lifting cam 103 through the lifting link 105, and the control shaft 120 is transmission-connected to the shear foot control cam 104 through the shear foot link 106.

[0049] In this way, the motor 102 can simultaneously drive the control shaft 120 and the lifting shaft 119 to move, so that the movable shearing blade body 109 and the fixed shearing blade body 110 move closer to the electronic component and realize the shearing operation, which is low in cost and small in size.

[0050] Please refer to Figure 2 、 Figure 3 as well as Figure 4 In this embodiment, the shear foot detection mechanism of the horizontal conjoined plug-in machine further includes a bidirectional lead screw 111 , a sliding seat 112 and a lifting follower block 121 .

[0051] 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. This allows the lifting shaft 119 to drive the lifting seats 108 to move up and down stably.

[0052] 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.

[0053] Please refer to Figure 3 and Figure 4 , wherein the lifting follower block 121 is fixedly connected to one end of the lifting shaft 119. The lifting seat 108 is connected to the lifting follower block 121 in a transverse sliding manner, and the transverse sliding direction of the lifting seat 108 is parallel to the sliding direction of the sliding seat 112.

[0054] Specifically, a groove is provided on the lifting follower block 121, and track bars are provided on the two opposite inner walls of the groove. Slide grooves 1081 for sliding connection with the track bars are provided on both sides of the lifting seat 108. The lateral sliding connection between the lifting seat 108 and the lifting follower block 121 is realized through the sliding cooperation between the slide grooves 1081 and the track bars.

[0055] Please refer to Figure 1 and Figure 2 In this embodiment, the fixed base 101 includes a frame 1011, which includes two first frame side panels and two second frame side panels arranged opposite to each other. The frame 1011 is very convenient for stably and compactly arranging components such as the bidirectional screw 111 and the sliding base 112.

[0056] A bidirectional lead screw 111 is rotatably connected between the two first frame side panels. One end of a sliding seat 112 is transmission-connected to the bidirectional lead screw 111 via a nut block 113. The other end of the sliding seat 112 is slidably connected to one of the second frame side panels. A sensor 117 is provided on the other second frame side panel. A sensing plate 118 is provided on one side of the nut block 113 for sensing by the sensor 117. The sensor 117 can be used to provide feedback on the position of the two sliding seats 112 by sensing the position of the sensing plate 118.

[0057] Please refer to Figure 3-Figure 5 In this embodiment, the shear foot detection mechanism of the horizontal conjoined plug-in machine further includes a shear foot follower block 122 , a linkage rod 123 , a transfer rod 124 , and a shear foot spring 127 .

[0058] The scissor foot follower block 122 is fixedly connected to one end of the control shaft 120, the movable scissor foot blade body 109 is rotatably connected to the lifting seat 108, and a linkage rod 123 is slidably arranged in the lifting seat 108. One end of the linkage rod 123 contacts the scissor foot follower block 122, and the other end of the linkage rod 123 is transmission-connected to the movable scissor foot blade body 109 via the adapter rod 124. In this way, the control shaft 120 can drive the movable scissor foot blade body 109 to rotate to perform the scissoring operation.

[0059] One end of the shear foot spring 127 is connected to the linkage rod 123, and the other end of the shear foot spring 127 is connected to the lifting seat 108. The shear foot spring 127 is used to pull the linkage rod 123 to maintain contact with the shear foot follower block 122, so that the control shaft 120 can stably and synchronously drive the movable shear foot blade 109 to rotate.

[0060] Specifically, the lifting base 108 is provided with a relief groove for accommodating the scissor foot spring 127. A first connecting rod 125 is provided on one side of the linkage rod 123 and is located within the relief groove. A second connecting rod 126 is provided on the inner wall of the relief groove. The ends of the scissor foot spring 127 are connected to the first connecting rod 125 and the second connecting rod 126, respectively. Furthermore, one end of the linkage rod 123 is provided with a pressure wheel 1231 for contacting the scissor foot follower block 122.

[0061] Please refer to Figure 2 In this embodiment, a lifting connection ring 115 is fixedly mounted on the lifting shaft 119. A lifting connection groove is formed along the circumference of the lifting connection ring 115. Two lifting transmission posts 1051 are disposed opposite one end of the lifting link 105. These two lifting transmission posts 1051 are slidably inserted into opposite sides of the lifting connection groove. This facilitates the assembly of the lifting link 105 and the lifting connection ring 115, and ensures stable transmission.

[0062] A scissor pin connecting ring 116 is fixedly mounted on the control shaft 120. A scissor pin connecting groove is formed along the circumference of the scissor pin connecting ring 116. Two scissor pin transmission posts 1061 are disposed opposite one end of the scissor pin connecting rod 106. These two scissor pin transmission posts 1061 are slidably inserted into opposite sides of the scissor pin connecting groove. This facilitates the assembly of the scissor pin connecting rod 106 and the scissor pin connecting ring 116, and ensures stable transmission.

[0063] Please refer to Figure 1 and Figure 2 In this embodiment, the lifting link 105 and the shear foot link 106 extend on opposite sides of the output shaft of the motor 102 respectively. The shear foot detection mechanism of the horizontal conjoined plug-in machine is installed on the mounting frame. The lifting link 105 is connected to the mounting frame through the first tensioning spring 1141. The first tensioning spring 1141 is used to pull the lifting link 105 to maintain contact with the shear foot lifting cam 103. The shear foot link 106 is connected to the mounting frame through the second tensioning spring 1142. The second tensioning spring 1142 is used to pull the shear foot link 106 to maintain contact with the shear foot control cam 104.

[0064] Please refer to Figure 2 More specifically, the shear foot lifting cam 103 includes a return-position arc side and a working-position arc side located on the circumference. The radius of the return-position arc side is larger than the radius of the working-position arc side. When the return-position arc side contacts the lifting link 105, it causes the lifting shaft 119 to move away from the electronic component.

[0065] The shear control cam 104 includes a shearing position arcuate side and a standby position arcuate side located on the circumference. The radius of the shearing position arcuate side is larger than the radius of the standby position arcuate side. When the shearing position arcuate side contacts the shear connecting rod 106, it causes the control shaft 120 to move toward the electronic component, thereby driving the movable shear blade 109 to rotate toward the fixed shear blade 110 to perform the shearing operation.

[0066] When the lifting link 105 contacts the side of the return position arc, the shearing link 106 contacts the side of the standby position arc, indicating that the device is far away from the electronic component. When the lifting link 105 contacts the side of the working position arc, the shearing link 106 contacts the side of the shearing position arc, indicating that the device is close to the electronic component and is performing the shearing operation.

[0067] Please refer to Figure 2 Specifically, one end of the lifting link 105 is provided with a first roller 1052 for contacting the scissor foot lifting cam 103, thereby improving the smoothness of the scissor foot lifting cam 103 driving the lifting link 105. One end of the scissor foot link 106 is provided with a second roller 1062 for contacting the scissor foot control cam 104, thereby improving the smoothness of the scissor foot control cam 104 driving the scissor foot link 106.

[0068] Please refer to Figure 6 The pin shear detection mechanism of the horizontal, connected plug-in machine in this embodiment also includes a detection rod 130, which is disposed at the shearing end of the movable pin shear blade 109. One end of the detection rod 130 cooperates with the fixed pin shear blade 110 to shear the leads of electronic components. The other end of the detection rod 130 is connected to a corresponding detection device via a lead. While the electronic component leads are being sheared, corresponding tests, such as pressure-sensitive testing, can be performed simultaneously, resulting in high work efficiency.

[0069] Please refer to Figure 3 and Figure 6 In this embodiment, the fixed shearing blade body 110 includes a shearing groove 128, with a shearing opening 1101 and a working opening 1102 respectively provided on adjacent sides of the shearing groove 128. The shearing opening 1101 is located on the side of the shearing groove 128 facing away from the lifting base 108, and the working opening 1102 is used for the detection rod 130 to enter the shearing groove 128. A bending block 1301 is provided on one end of the detection rod 130, near the shearing groove 128. The bending block 1301 is offset from the surface of the fixed shearing blade body 110 facing away from the lifting base 108. The bending block 1301 and the surface of the fixed shearing blade body 110 facing away from the lifting base 108 perform offset shearing, thereby shearing the pins of the electronic components within the shearing groove 128.

[0070] Furthermore, the shear foot detection mechanism of the horizontal combined plug-in machine also includes a waste adsorption tube 129, which is connected to the inner cavity of the shear foot groove 128, and the waste adsorption tube 129 is connected to the suction device. The waste adsorption tube 129 and the suction device can also be provided with a ventilation filter, so that the waste adsorption tube 129 can adsorb the shear foot waste into the ventilation filter, similar to the structure of a vacuum cleaner.

[0071] The working principle of the present invention is as follows: when the pins of electronic components are sheared, the motor 102 drives the shearing pin lifting cam 103 and the shearing pin control cam 104 to rotate.

[0072] When the working position arc side of the shear foot lifting cam 103 begins to contact the lifting connecting rod 105, the shear foot position arc side of the shear foot control cam 104 gradually contacts the shear foot connecting rod 106.

[0073] Under the pull of the first tensioning spring 1141, the lifting link 105 causes the control shaft 120 to move toward the electronic component, driving the lifting base 108 to move toward the electronic component, causing the electronic component's pins to extend from the cutting opening 1101 into the cutting groove 128. Under the pressure of the cutting control cam 104, the cutting link 106 drives the control shaft 120 toward the electronic component, thereby driving the movable cutting blade 109 to rotate toward the fixed cutting blade 110, cutting the electronic component's pins in the cutting groove 128. The waste suction pipe 129 then absorbs the pin waste in the cutting groove 128.

[0074] This completes the process of the shearing foot detection of the shearing foot detection mechanism of the horizontal conjoined plug-in machine of this embodiment.

[0075] The following is a second embodiment of a shear pin detection mechanism for a horizontal, conjoined plug-in machine, provided by the present invention, that addresses the aforementioned technical issues. This embodiment differs from the first embodiment primarily in that an adjustment mechanism for a first roller is provided on the lifting link. Adjusting the position of the first roller relative to the lifting link changes the distance that the shear pin lifting cam drives the lifting axis away from the electronic component, thereby varying the shear pin length of the electronic component. Structures common to the first embodiment are not further detailed in this embodiment.

[0076] The shearing detection mechanism of the horizontal combined plug-in machine of this embodiment can meet different shearing requirements by setting an adjustment mechanism that can adjust the first roller, which can further solve the problem that the shearing equipment in the prior art has low compatibility with the shearing processing of electronic components and low efficiency in processing products of different batches and different processing requirements.

[0077] Please refer to Figure 7 and Figure 8 In this embodiment, the lifting link 105 is provided with a receiving slot for mounting a first roller 1052. The first roller 1052 passes through the receiving slot and contacts the shear foot lifting cam 103. A rotating shaft 21 is provided on either side of the first roller 1052. A long slot 22 is provided on either side of the lifting link 105, connecting to the receiving slot. The rotating shaft 21 and the long slot 22 form a sliding and rotating engagement, with the sliding path of the rotating shaft 21 being perpendicular to the axial direction of the shear foot lifting cam 103. A fixing hole 23 is provided on the side of the lifting link 105 facing away from the shear foot lifting cam 103, connecting to the long slot 22.

[0078] A fixed plate 24 is provided on the side of the lifting link 105 facing away from the shear foot lifting cam 103. A movable plate 25 is provided on the side of the fixed plate 24 facing away from the shear foot lifting cam 103. A screw 26 passes through the movable plate 25 and is threadedly connected to the fixed plate 24. Extrusion rods 251 are provided at both ends of the movable plate 25. These extrusion rods 251 slide within the fixing holes 23 and contact the rotating shaft 21. Simultaneously, the first tensioning spring 1141 pulls the lifting link 105 toward the shear foot lifting cam 103, ensuring that the first roller 1052 is always in contact with the shear foot lifting cam 103, and the rotating shaft 21 is also always in contact with the extrusion rods 251. By turning the screws 26, the length of the extrusion rods 251 extending into the fixing holes 23 can be adjusted, thereby adjusting the position of the first roller 1052 relative to the lifting link 105.

[0079] like Figure 7 , Figure 7 The middle extrusion rod 251 and the fixing hole 23 are in a disassembled state. When the extrusion rod 251 extends a long distance into the fixing hole 23, the first roller 1052 protrudes a greater distance from the side of the lifting link 105 toward the shearing foot lifting cam 103. This allows the shearing foot lifting cam 103 to drive the lifting shaft 119 to move a greater distance, allowing the movable shearing blade 109 and the fixed shearing blade 110 to cut a longer length of the pin.

[0080] 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 side of the lifting link 105 toward the shear foot lifting cam 103 is smaller, so that the shear foot lifting cam 103 drives the lifting shaft 119 to move a shorter distance, and the length of the pin cut off by the movable shear foot blade body 109 and the fixed shear foot blade body 110 is shorter.

[0081] Please refer to Figure 8 Furthermore, a limit ring 27 is provided on the side of the movable plate 25 facing away from the shear foot lifting cam 103. The screw 26 is located within the limit ring 27. Two operating plates 28 are elastically slidably provided in the radial direction on both sides of the screw 26. The surfaces of the operating plates 28 are parallel to the radial plane of the screw 26. Specifically, a spring can be provided between the two operating plates 28 to achieve the sliding arrangement of the two operating plates 28.

[0082] The inner wall of the limiting ring 27 is provided with a plurality of scale grooves 271 along the inner circumference. The operating plate 28 includes a limiting position limited to the scale groove 271 and a movable position avoiding the scale groove 271 on the sliding track. Figure 8 This is a schematic diagram, and the component dimensions and the number of scale grooves 271 in the figure are not intended to limit the present invention.

[0083] The outer sides of the operating plates 28 can be equipped with lugs 281 for easy handling. By pinching the lugs 281 of the two operating plates 28, the plates 28 can be slid toward each other until they are in the active position. This allows the screw 26 to be rotated to adjust the degree of compression of the extrusion rod 251 on the rotating shaft 21. When the two operating plates 28 are released, the spring pushes the two plates 28 away from each other, and the operating plates 28 snap into the graduated groove 271. The combination of the operating plates 28 and the graduated groove 271 not only prevents the screw 26 from loosening, but also provides feedback on the angle of rotation of the screw 26. This provides a stable structure and convenient operation.

[0084] The shearing foot detection mechanism of the horizontal combined plug-in machine of the present invention slides the control shaft through the inside of the lifting shaft, and the motor can simultaneously drive the control shaft and the lifting shaft to move, so that the movable shearing foot blade body and the fixed shearing foot blade body move closer to the electronic component and realize the shearing foot operation, which has low cost and small size.

[0085] In addition, the movable shearing foot blade body and the fixed shearing foot blade body are driven by the first tensioning spring to pull the lifting connecting rod to move toward the direction of the electronic component, so that the movable shearing foot blade body and the fixed shearing foot blade body elastically and flexibly approach and contact the pins of the electronic component, and then the shearing foot control cam squeezes the shearing foot connecting rod, so that the movable shearing foot blade body and the fixed shearing foot blade body can forcefully shear the pins of the electronic component, with little impact damage to the electronic component and good shearing effect.

[0086] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
