[0002] Electronic components usually have multiple pins for connecting with other components. The pins are usually flat structures with a width direction and a thickness direction. When multiple pins are arranged at the same side of the electronic component body with the width direction of each pin along the same side of the electronic component body, such as the MOS tube shown in Figure 11 , the spacing between adjacent pins of the MOS tube is small, which causes the problem of short circuit due to the adhesion of adjacent pins during welding, and the problem of low one-time success rate during assembly blind insertion.

[0003] Therefore, the pins of the electronic component are usually twisted 90 degrees before welding, so that the positions of the width direction and the thickness direction of the pins are exchanged, that is, the thickness direction of each pin of the electronic component is arranged along the side of the package, so as to increase the spacing between adjacent pins and reduce the problem of short circuit caused by the adhesion of the pins of the electronic component during welding, and improve the one-time success rate during assembly blind insertion, such as the MOS tube shown in Figure 12 .

[0063] The present application provides a foot twisting tool.

[0064] Please refer to Figures 5 to 7 The foot twisting tool 100 provided by the present application comprises:

[0065] The fixing mechanism 300 is used for fixing the electronic element 2000.

[0066] The torsion foot assembly 210 comprises a plurality of torsion foot pieces 211 arranged at intervals, and the end of the torsion foot piece 211 is provided with a torsion foot part for fixedly matching with the pin 2100 of the electronic element 2000.

[0067] The driving assembly is connected with the torsion foot assembly 210, and the driving assembly can drive the torsion foot piece 211 to rotate, so that the pin 2100 is twisted around the extension direction of the pin 2100.

[0068] The torsion foot tool 100 of the technical scheme of the present application comprises a fixing mechanism 300, and the driving assembly and the torsion foot assembly 210 connected with each other, the fixing mechanism 300 is used for fixing the electronic element 2000; the torsion foot assembly 210 comprises a plurality of torsion foot pieces 211 corresponding to the pin 2100 and arranged at intervals, and the end of the torsion foot piece 211 is provided with a torsion foot part for fixedly matching with the pin 2100 of the electronic element 2000; the driving assembly can also drive the torsion foot piece 211 to rotate, so that the pin 2100 of the electronic element 2000 can be twisted around the extension direction of the pin 2100. It can be understood that the extension direction of the pin 2100 is the direction in which the pin 2100 extends outwardly away from the element body 2200, when the driving assembly drives the torsion foot piece 211 to rotate, the torsion foot part of the torsion foot piece 211 is fixedly matched with the pin 2100, thereby driving the pin 2100 to rotate, the pin 2100 can rotate around the axis of the extension direction of the pin 2100, the pins 2100 of the electronic element 2000 are generally arranged at intervals according to the width direction of the pin 2100, as shown in Figure 11 The width of the pin 2100 is greater than the thickness, so that the position of the pin 2100 in the width direction and the position in the thickness direction are changed by the operation of twisting the pin 2100, for example, the pins 2100 of the electronic element 2000 are arranged at intervals according to the thickness direction of the pin 2100 after being twisted, as shown in Figure 12 Thus, the width between adjacent pins 2100 is increased, when the electronic element 2000 is connected with other electronic elements, the problem of short circuit caused by the adhesion between the pins 2100 during welding of the electronic element 2000 can be reduced, and the one-time success rate during blind insertion assembly can be improved, and the assembly efficiency is improved. In the technical scheme of the present application, the driving assembly of the torsion foot tool 100 drives the pin 2100 of the electronic element 2000 to automatically twist, instead of manually twisting the pin 2100 of the electronic element 2000, which not only saves manpower and improves production efficiency, but also avoids the phenomenon of electrostatic breakdown caused by manual operation, and reduces the risk of electrostatic breakdown of the electronic element 2000.

[0069] In one embodiment, the number of the twisting members 211 in the twisting assembly 210 is the same as the number of the pins 2100 of the electronic component 2000 that need to be twisted. For example, when the number of the pins 2100 of an electronic component 2000 that need to be twisted is three, the number of the twisting members 211 in the twisting assembly 210 is also three. The position of each twisting member 211 corresponds to the position of each pin 2100 of the electronic component 2000.

[0070] In one embodiment, the twisting part provided at the end of the twisting member 211 can be a fixed groove 2111, the pin 2100 is inserted into the fixed groove 2111, and the shape of the fixed groove 2111 is adapted to the shape of the pin 2100. For example, the shape of the pin 2100 is rectangular, and the shape of the fixed groove 2111 is also rectangular. The cross-sectional shape of the pin 2100 can also be rhombic, hexagonal, etc., which is not limited herein. When the twisting assembly 210 is close to the pin 2100, each pin 2100 can be inserted into the fixed groove 2111, respectively. Because the shape of the fixed groove 2111 is adapted to the shape of the pin 2100, the pin 2100 can be fixed, so that when the twisting member 211 is twisted, the twisting member 211 can drive the pin 2100 to be twisted synchronously, and the pin 2100 can be twisted. In this embodiment, the fixed groove 2111 is used to fix the twisting member 211 and the pin 2100, which has good stability and can automatically twist the pin 2100 without manual operation, thereby improving the production efficiency.

[0071] In one embodiment, the twisting member 211 is in a tubular structure, i.e., a twisting pipe, and the fixed groove 2111 is provided at the end of the twisting pipe close to the pin 2100. The tubular structure of the twisting member 211 makes the twisting pipe easy to rotate, thereby reducing the difficulty of control.

[0072] In one embodiment, the twisting part can also be a clamping structure that abuts against two opposite sides of the pin 2100 to clamp and fix the pin 2100. When the twisting member 211 is driven to rotate by the driving assembly, the clamping structure also rotates, so that the pin 2100 rotates around the axis of the extension direction of the pin 2100 by a certain angle, thereby increasing the distance between the pins 2100. In order to easily twist the pin 2100, the clamping structure can abut against two opposite sides of the pin 2100 with larger areas, so as to increase the abutting area.

[0073] Please refer to Figures 5 to 10In one embodiment of the present application, the driving assembly comprises a first driving mechanism 12, which comprises a first driving member 121 and a transmission member, the output end of the first driving member 121 is connected with the transmission member, and the transmission member is in transmission connection with the leg twisting member 211; the first driving member 121 drives the transmission member to move, so as to drive the leg twisting member 211 to rotate, so that the lead leg 2100 is twisted around the extension direction of the lead leg 2100.

[0074] In the technical scheme of the present embodiment, the driving assembly comprises a first driving mechanism 12 and a transmission member, the first driving mechanism 12 is used for outputting driving force, and the transmission member is used for transmitting the driving force outputted by the first driving mechanism 12 to the leg twisting member 211. It can be understood that the driving force outputted by the first driving mechanism 12 can be rotational motion or linear motion. The transmission member has various forms, for example, the transmission member can be a connecting rod mechanism 123, the transmission member can also be a transmission gear, a transmission chain, a gear and rack structure, etc., and the specific structure of the transmission member is not limited herein. The first driving mechanism 12 outputs driving force of rotational motion or linear motion, drives the transmission member to rotate or swing, and then drives the leg twisting member 211 to rotate through the transmission member, so as to realize that the lead leg 2100 rotates around the axis with the extension direction as the axis, that is, the lead leg 2100 can realize automatic leg twisting, so that manual leg twisting is not needed, and the production efficiency is improved.

[0075] Please refer to Figures 5 to 7 In one embodiment of the present application, the transmission member comprises a guide limiting member 122 and a plurality of connecting rod mechanisms 123, the output end of the first driving member 121 is connected with the guide limiting member 122, so as to drive the guide limiting member 122 to move in translation, the guide limiting member 122 is provided with a plurality of guide limiting grooves 1221 which are arranged at intervals, the extension direction of the guide limiting groove 1221 is arranged at an angle with the translation direction of the guide limiting member 122; one end of the connecting rod mechanism 123 is movably inserted into the guide limiting groove 1221, and the other end is fixedly connected with the leg twisting member 211.

[0076] In the technical scheme of the embodiment, the first driving member 121 outputs horizontal linear motion, and the first driving member 121 can be a cylinder or a linear motor or the like. When the first driving member 121 is a cylinder, the push rod part of the cylinder is connected with the guide limiting member 122. Specifically, the guide limiting groove 1221 on the guide limiting member 122 extends in a vertical direction, one end of the connecting rod mechanism 123 is movably inserted into the guide limiting groove 1221, and the other end of the connecting rod mechanism 123 is fixedly connected with the side wall of the torsion leg member 211. When the push rod part of the cylinder pushes the guide limiting member 122 to move in a horizontal direction, one end of the connecting rod mechanism 123 moves in a vertical direction in the guide limiting groove 1221, and in this process, the connecting rod mechanism 123 swings to drive the torsion leg member 211 to rotate, so that the lead leg 2100 rotates around the extension direction of the lead leg 2100 as the axis, that is, the lead leg 2100 can automatically twist the leg, so that manual leg twisting is not required, and the production efficiency is improved.

[0077] Please continue to refer to Figures 5 to 7 In an embodiment of the application, the connecting rod mechanism 123 includes a limiting rod 1231 and a connecting rod 1232, the limiting rod 1231 is movably inserted into the guide limiting groove 1221, one end of the connecting rod 1232 is in transmission connection with one end of the limiting rod 1231, and the other end of the connecting rod 1232 is fixedly connected with the torsion leg member 211. If the first driving member 121 drives the guide limiting member 122 to move in translation, the limiting rod 1231 moves in the guide limiting groove 1221 to drive the torsion leg member 211 to rotate.

[0078] In the technical scheme of the embodiment, the connecting rod mechanism 123 includes a limiting rod 1231 and a connecting rod 1232, when the first driving member 121 drives the guide limiting member 122 to move in a horizontal direction, the limiting rod 1231 is inserted into the guide limiting groove 1221 and can only move in a vertical direction along the extension direction of the guide limiting groove 1221 to drive the connecting rod 1232 in transmission connection with the limiting rod 1231 to rotate, and then drive the torsion leg member 211 to rotate, so that automatic leg twisting of the lead leg 2100 is realized. The first driving mechanism 12 in the embodiment has a simple structure, is not easy to wear, and is easy to process. Moreover, the extension length of the guide limiting groove 1221 can be controlled to control the rotation angle of the connecting rod 1232, and then the angle of rotation of the torsion leg member 211 is controlled. This way of controlling the rotation angle is easier to grasp than controlling the angle of the rotation shaft, so that the length of the guide limiting groove 1221 can be designed and adjusted according to actual production requirements to control the rotation angle of the lead leg 2100 rotating around the extension direction of the lead leg 2100.

[0079] Please refer to Figure 8 and Figure 9In an embodiment of the present application, the guide limiting piece 122 comprises a connecting block 1222 and a guide limiting block 1223, the connecting block 1222 is connected with the output end of the first driving piece 121; the guide limiting block 1223 is connected with the connecting block 1222 and protrudes from the connecting block 1222 and is arranged at an angle with the connecting block 1222, the guide limiting block 1223 comprises a plurality of guide limiting portions arranged at intervals along the extension direction of the torsion leg piece 211, the guide limiting portions are formed with guide limiting grooves 1221, and the plurality of guide limiting grooves 1221 are arranged at a staggered position.

[0080] In the technical scheme of the embodiment, the guide limiting block 1223 protrudes from the connecting block 1222, the angle between the connecting block 1222 and the guide limiting block 1223 is 90 degrees, and the connecting block 1222 is used to realize the connection between the guide limiting block 1223 and the first driving piece 121. The guide limiting block 1223 and the connecting block 1222 are an integral structure to improve the structural strength of the guide limiting piece 122. The connecting block 1222 is substantially square in structure, facilitating the fixed connection with the push plate part of the first driving piece 121. The guide limiting block 1223 comprises a plurality of guide limiting portions arranged at intervals along the extension direction of the torsion leg piece 211 and in a straight line, and the extension length of each guide limiting portion in the direction away from the connecting block 1222 gradually increases, each guide limiting portion is formed with a guide limiting groove 1221, so that the plurality of guide limiting grooves 1221 are arranged at a staggered position in the arrangement direction of the plurality of torsion leg pieces 211. In addition, in order to facilitate the stable rotation of the connecting rod mechanism 123 to drive the rotation of the torsion leg piece 211, the guide limiting groove 1221 can be arranged on the side of the guide limiting portion facing the lead 2100. In this way, each connecting rod mechanism 123 can be arranged at the same length, so as to facilitate the connection of each connecting rod mechanism 123 with each torsion leg piece 211 arranged at the same angle, the same length and intervals, thereby ensuring that each torsion leg piece 211 has the same rotation angle and improving the consistency of the torsion angle processing of each lead 2100 in the same electronic component 2000.

[0081] In an embodiment, the guide limiting block 1223 can only comprise one guide limiting portion, that is, if there are a plurality of torsion leg pieces 211, the plurality of guide limiting grooves 1221 are arranged on the same guide limiting portion, and the plurality of guide limiting grooves 1221 are arranged at a staggered position in the arrangement direction of the plurality of torsion leg pieces 211, thereby ensuring that each torsion leg piece 211 has the same rotation angle and improving the consistency of the torsion angle processing of each lead 2100 in the same electronic component 2000.

[0082] Please refer to Figures 8 to 10In an embodiment of the present application, the connecting rod mechanism 123 comprises a limiting rod 1231 and connecting rods 1232, each connecting rod 1232 is fixedly connected with the torsion foot 211 via the gap between the guiding limiting part.
