[0001] The invention relates to the technical field of electronic device production, and in particular to a sensor pin shearing device. Background Art

[0002] With the development of science and technology, the extensive application of electronic equipment has led to a sharp increase in the demand for electrical components. The final stage of sensor production is to replace the original signal transmission method with metal pins with wire leads. During the process, the metal pins need to be cut to a specified length. The metal pins are linear materials. According to the cross-sectional shape, the wires are round, square, oval, trapezoidal and special-shaped.

[0003] When shearing a metal pin with a square cross-section, the metal pin is cut off by a cutter. During the cutting process of the metal pin, friction occurs between the cutter and the cut surface of the metal pin. After the metal pin is cut off, a certain length of burrs will be generated on the cut surface of the metal pin along the cutting direction of the cutter. The tip of the burrs is relatively sharp. When installing the sensor, the hand will contact the cut surface of the metal pin, and there will be sharp burrs on the cut surface of the metal pin. The sharp burrs on the cut surface will scratch the hand, causing scratches on the hand. The cutting of the metal pin will produce burr tips, which will reduce the shearing effect of the metal pin. Summary of the invention

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1: Reference Figure 1-3 , a sensor pin shearing device comprises a base frame 1, a fixing frame 2 is fixedly connected to the upper end of the base frame 1, a plurality of pin holes 3 are opened at equal intervals on the upper end of the fixing frame 2 along the length direction, a slag discharge port 4 is opened on the bottom end of the fixing frame 2, and the slag discharge port 4 is connected to the pin hole 3, a collecting box 5 is connected to the base frame 1, and the upper end of the collecting box 5 is connected to the slag discharge port 4, an electric telescopic rod 6 is fixedly connected to the fixing frame 2, and a cutter 7 is fixedly connected to the telescopic end of the electric telescopic rod 6, a cutting groove 8 is opened on the base frame 1, and the cutter 7 cooperates with the cutting groove 8, and the cutting groove 8 is connected to the pin hole 3, a movable hole 9 is opened on the fixing frame 2, and the movable hole 9 is connected to the pin hole 3, and a fitting mechanism 10 for fixing the sensor pin is connected to the movable hole 9, a motor 11 is fixedly connected to the fixing frame 2, a mounting groove 12 is opened on the fixing frame 2, and an opening is opened on the mounting groove 12, and the opening is connected to the pin hole 3, and a grinding roller 13 is fixedly connected to the output end of the motor 11, and the grinding roller 13 cooperates with the opening;

[0026] The fitting mechanism 10 includes a groove seat 101, which is fixedly connected to the fixed frame 2, and a movable plate 102 is slidably connected to the groove seat 101, one end of the movable plate 102 is fixedly connected to an extrusion block 103, the extrusion block 103 is slidably connected to the movable hole 9, and a spring 104 is fixedly connected to the movable plate 102, and one end of the spring 104 is fixedly connected to the fixed frame 2.

[0027] Working principle: when shearing the pin of the sensor, pull the movable plate 102, and the movable plate 102 moves smoothly in the horizontal direction under the limit of the groove seat 101. After the movable plate 102 moves, it drives the extrusion block 103 to move, so that the extrusion block 103 is separated from the pin hole 3, and the pin hole 3 is in a conducting state. After the movable plate 102 moves, it pulls the spring 104 at the same time. The spring 104 generates elastic force after being pulled. After the extrusion block 103 is separated from the pin hole 3, the pin of the sensor is inserted into a different pin hole 3, and the sensor body contacts the upper end of the fixing frame 2. Then release the movable plate 102, and under the action of the elastic force of the spring 104, the movable plate 102 is driven to move toward the fixing frame 2. The movable plate 102 drives the extrusion block 103 to move. After moving a distance, the extrusion block 103 contacts the pin of the sensor and squeezes and fixes it. One side of the pin of the sensor fits with the inner wall of the pin hole 3, so that the pin of the sensor does not move during shearing, thereby improving the shearing effect of the sensor pin.

[0028] The controller controls the electric telescopic rod 6 to be powered on and started. After the electric telescopic rod 6 is started, it drives the cutter 7 to move a set distance in the direction of the fixed frame 2 and then resets. During the movement of the cutter 7 in the direction of the fixed frame 2, it gradually inserts into the cutting groove 8. After the cutter 7 moves a certain distance in the direction of the fixed frame 2, it contacts the pin of the sensor. After the cutter 7 continues to move, it cuts off the pin of the sensor. After the cutter 7 moves a set distance in the direction of the fixed frame 2, it cuts off the pin of the sensor. The cut pin is released from the slag discharge port 4. The released pin falls into the collection box 5 and is collected by the collection box 5 to prevent the pin from being scattered.

[0029] When the electric telescopic rod 6 drives the cutter 7 to move a set distance toward the fixed frame 2, the controller controls the motor 11 to start. After the motor 11 is started, it drives the grinding roller 13 to rotate. One side of the grinding roller 13 passes through the opening and is flush with the inner wall of the pin hole 3. The pin of the sensor contacts the grinding roller 13. Under the extrusion of the extrusion block 103, the pin of the sensor contacts the inner wall of the pin hole 3. When the sensor is pulled upward, the sensor drives the pin to move. During the upward movement of the sensor pin, the burr on the cut surface contacts the inner wall of the pin hole 3. The burr rubs against the inner wall of the pin hole 3, and the burr on the cut surface is rubbed. The cut surface of the sensor pin moves upward for a distance and then contacts the rotating grinding roller 13. The cut surface of the sensor pin moves upward, and the grinding roller 13 rotates downward. The burr generated on the cut surface of the sensor pin contacts the grinding roller 13. The grinding roller 13 grinds the burr generated on the cut surface for a second time, thereby reducing the sharpness and length of the burr on the cut surface. When the cut surface of the sensor pin is held by the hand, it is not easy to cause scratches to the hand, thereby improving the shearing effect on the sensor pin.

[0030] Embodiment 2: In embodiment 1, after the sensor pin is cut off, the sensor pin is pulled upward, and the extrusion block 103 extrudes the sensor pin, one side of the sensor pin contacts the extrusion block 103, and the other side of the sensor pin contacts the inner wall of the pin hole 3. During the upward movement of the sensor pin, it is squeezed by the extrusion block 103 and rubbed by the inner wall of the pin hole 3. During the upward movement of the sensor pin, it encounters a large resistance, which makes it inconvenient to pull the sensor upward. Figure 4-6As another preferred embodiment of the present invention, on the basis of embodiment 1, a power assist mechanism 14 for facilitating pulling of the sensor pin is connected to the fixing frame 2, the power assist mechanism 14 comprises a first groove 141, the first groove 141 is provided in the fixing frame 2, the first groove 141 is connected to the pin hole 3, a plurality of first rotating rollers 142 are connected in the first groove 141 at equal intervals along the length direction, a rotating shaft 143 is rotatably connected to the fixing frame 2, one end of the rotating shaft 143 extends into the first groove 141 and is fixedly connected to a pushing roller 144, the pushing roller 144 is located at the inner bottom end of the first groove 141, the other end of the rotating shaft 143 is fixedly connected to a first gear 145, the output end of the motor 11 is fixedly connected to a second gear 146, the second gear 146 is meshedly connected to the first gear 145, a second groove 147 is provided on the extrusion block 103, a second rotating roller 148 is rotatably connected in the second groove 147, and the side of the second rotating roller 148 extends out of the second groove 147.

[0031] Working principle:

[0032] The second rotating roller 148 is rotatably connected to the second groove 147, and the side of the second rotating roller 148 extends out of the second groove 147. The extrusion block 103 rolls with one side of the sensor pin through the second rotating roller 148. A plurality of first rotating rollers 142 are installed in the first groove 141, and a plurality of first rotating rollers 142 roll with the other side of the sensor pin. When the sensor is pulled upward, the sensor pin is respectively rotated with the second rotating roller 148 and the first rotating roller 142, so as to reduce the friction of the sensor pin during the upward movement, thereby reducing the resistance during the upward movement, and facilitating the upward pulling of the sensor pin.

[0033] At the same time, the output end of the motor 11 drives the second gear 146 to rotate, the second gear 146 drives the first gear 145 to rotate, the first gear 145 drives the rotating shaft 143 to rotate, the rotating shaft 143 drives the pushing roller 144 to rotate, and after the second gear 146 and the first gear 145 are reversing, the rotation direction of the pushing roller 144 is opposite to the rotation direction of the grinding roller 13. After the pushing roller 144 rotates, it pushes the sensor pin upward, and the sensor pin is subjected to an upward thrust, which facilitates pulling the sensor upward.

[0034] Embodiment 3: In Embodiment 2, when the burrs generated on the cut surface are polished by the polishing roller 13, the sensor pin continues to contact the polishing roller 13 during the upward movement, and the contact surface between the sensor pin and the polishing roller 13 is polished by the polishing roller 13. The debris generated by the polishing remains on the sensor pin. After the sensor pin contacts the pushing roller 144, the debris on the sensor pin falls on the pushing roller 144, which easily causes the contact between the pushing roller 144 and the polishing roller 13 to slip, thereby reducing the pushing effect on the sensor pin. Figure 7-8As another preferred embodiment of the present invention, on the basis of Embodiment 2, an anti-sticking mechanism 15 for reducing the slipping of the push roller 144 is connected in the first groove 141, and the anti-sticking mechanism 15 includes a mounting plate 151, and the mounting plate 151 is fixedly connected to the first groove 141, and a plurality of fixed strips 152 are connected to the mounting plate 151 at equal intervals along the length direction, and a wiping block 153 is fixedly connected to each fixed strip 152, and the plurality of wiping blocks 153 are in contact with the first rotating roller 142 and the push roller 144.

[0035] Working principle:

[0036] The mounting plate 151 is connected to the fixing bar 152, and the fixing bar 152 fixes the wiping block 153. The pushing roller 144 contacts the wiping block 153 during rotation, and the pushing roller 144 and the wiping block 153 slide relative to each other. The wiping block 153 rubs and cleans the surface of the pushing roller 144, so that the debris on the surface of the pushing roller 144 is separated from the pushing roller 144, avoiding the debris from falling on the pushing roller 144 and not affecting the pushing of the sensor pin by the pushing roller 144. The contact between the pushing roller 144 and the sensor pin is not easy to slip, thereby improving the pushing effect on the sensor pin.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
