Abstract
Description
Technical Field
[0001] The utility model relates to a resistor pin-splitting device, which is used for separating the pins of a thermistor by a specific distance. Background Art
[0002] Resistors, as electronic components, are widely used in electrical products. During the manufacturing process of these products, resistors need to be soldered to circuit boards or other components. However, due to the small size of resistors, soldering is often done manually, resulting in low soldering efficiency. Furthermore, with rising labor costs, manual soldering leads to high manufacturing costs.
[0003] Automated soldering equipment is urgently needed for resistors on existing production lines. Before processing, the two leads of thermistors can easily come into contact and overlap, preventing them from being soldered to other electronic components during the subsequent soldering process. To facilitate automated soldering, the two leads of the thermistor must be separated by a specific distance before soldering. Utility Model Content
[0004] The purpose of the utility model is to provide a resistor pin-splitting device, which can separate two pin lines of a resistor by a specific distance in an automated manner.
[0005] To achieve the above objectives, the present invention provides a resistor pin-splitting device comprising a first rotating disk and a guide mechanism. The first rotating disk is used to adsorb the resistors onto a circumferential surface at equal intervals. The guide mechanism comprises two magnetic members and two guide plates, which are arranged parallel to each other to form a guide channel for the resistors. At least a portion of the first rotating disk is positioned within the guide channel. The two magnetic members are arranged side by side at a predetermined angle, the predetermined angle being configured to cause the resistors to move along the guide channel toward the circumferential surface of the first rotating disk under the action of magnetic force. The resistor pin-splitting device also includes a pin-splitting pin, which is inserted between the two pin wires to separate them by a predetermined distance.
[0006] This resistor pin-splitting device, using a first turntable and a guide mechanism, automatically transports resistors to the pin-splitting process. During this process, a pin-splitting needle is inserted between the resistor's lead wires, forcing them to deform and separate them by a specific distance. This resistor pin-splitting device automatically separates the two resistor lead wires by a specific distance.
[0007] In one embodiment, the resistor pin-splitting device further includes an elastic preload mechanism positioned alongside the pin-splitting pin along the length of the resistor's lead wires. Prior to pin-splitting, the elastic preload mechanism flattens the overlapping lead wires, facilitating insertion of the pin-splitting pin between the two lead wires. This preload mechanism compresses the lead wires without causing deformation or damage.
[0008] In one embodiment, the elastic preload mechanism includes a compression rod and a compression spring mounted at its end. The compression spring applies pressure to the resistor leads, aligning them horizontally. Upon contacting the leads, the compression spring contracts, ensuring that the stacked leads are flattened while preventing deformation or damage.
[0009] In one embodiment, the resistor leg separation device further includes a lifting portion and a lateral push block, wherein the lifting portion is used to lift and absorb the resistor that has been transported to a predetermined position; and the lateral push block is used to push the resistor from the first turntable to the lifting portion.
[0010] In one embodiment, there are two first turntables arranged side by side, with a gap between the two first turntables, and at least a portion of the lifting portion is located in the gap.
[0011] In one embodiment, the lifting portion further includes a magnetic block and a groove for accommodating a resistor, and the magnetic block is used to adsorb the resistor on the lifting portion.
[0012] In one embodiment, the lifting portion is movable to approach and lift the resistor. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The structure and other aspects of the resistor leg splitting device of the present invention are further described in detail below through specific implementations and with reference to the accompanying drawings.
[0021] This utility model's resistor leg splitting device includes a feeder and a leg splitter. The structure and operating principle of the feeder are detailed in Chinese Patent No. 202110665072.8. This specification incorporates the disclosure of Chinese Patent No. 202110665072.8 by reference, and the disclosure of Chinese Patent No. 202110665072.8 constitutes the disclosure of this utility model.
[0022] like Figure 1-3 As shown, the resistor pin-splitting device of the present invention includes a bracket 10, a drive mechanism, a first rotating disk 12, and a guide mechanism 13. The first rotating disk 12 is rotatably mounted on the bracket 10 and rotates under the drive mechanism, which can be, for example, a motor. The resistor 14 can be, for example, a single-ended glass-sealed thermistor.
[0023] The guide mechanism 13 is located on one side of the first turntable 12 along its diameter. The guide mechanism 13 comprises two guide plates 131 and magnetic members 132. The guide plates 131 are arranged parallel to each other on either side of the first turntable 12, forming a guide channel for the resistor 14. The two magnetic members 132 are located on either side of the guide plates 131, creating a magnetic field within the guide channel. The distance between the two guide plates 131 is substantially equal to the length of the resistor 14. At least a portion of the first turntable 12 is located between the two magnetic members 132. The two magnetic members 132 are rectangular and arranged side by side in a trumpet-like shape, i.e., at a predetermined angle. The angle at which the two magnetic members 132 are arranged allows the resistor 14 to move along the guide channel toward the circumferential surface of the first turntable 12 under the influence of magnetic force, thereby being attracted to the circumferential surface of the first turntable 12. Specifically, a plurality of transverse grooves 121 are provided at equal intervals on the circumferential surface of the first transfer case 12 . Magnets are provided in the transverse grooves 121 , and the resistors 14 are accommodated and adsorbed in the grooves 121 .
[0024] In the present invention, a trumpet-shaped magnetic member 132 is provided within the guide mechanism 13, causing the resistor 14 within the guide channel of the guide mechanism 13 to continuously move toward the first turntable 12 under the action of magnetic force. Once the resistor 14 reaches the circumference of the first turntable 12, it is attracted by the magnets provided there. This enables automatic feeding of the resistor 14 through the guide mechanism 13 and the first turntable 12.
[0025] In a preferred embodiment, the resistor feeder of the present invention further includes a second turntable 15, which is located on one side of the first turntable 12. The diameter of the second turntable 15 is smaller than that of the first turntable 12, and a magnet for adsorbing the resistor 14 is also provided on the circumferential surface of the second turntable 15. The first turntable 12 rotates synchronously with the second turntable 15. When setting the positions of the first turntable 12 and the second turntable 15, it is necessary to ensure that the circumferences of the two are in an inscribed position; at the same time, when setting the transmission ratio of the first turntable 12 to the second turntable 15, it is necessary to ensure that the magnet on the first turntable 12 meets the magnet on the second turntable 15 at the tangent point. In a specific embodiment, the tangent point is located at the highest point of rotation of the first turntable 12.
[0026] By setting up the second turntable 15, the pin wire of the resistor 14 that has been adsorbed on the circumferential surface of the first turntable 12 is also adsorbed by the second turntable 15 at the intersection position, so that the pin wire of the resistor is in a straight posture, and the tail of the pin wire of the resistor will not be bent, ensuring that the pin wire of the resistor enters the next process in a straight posture.
[0027] The resistor pin-splitting device of the present invention also includes a pin-splitting portion 17, which is used to separate the two pins of the resistor 14 by a predetermined distance. In a specific embodiment, the pin-splitting portion 17 further includes a pin-splitting needle 171, a lifting portion 172, and a lateral push block 173. The pin-splitting needle 17 is mounted on a movable bracket 171a. The pin-splitting needle 171 can move up and down driven by the movable bracket 171a to be inserted between the two pins of the resistor 14 to separate the pins by a predetermined distance. The lifting portion 172 is used to lift and absorb the resistor 14 that has been transported to a predetermined position, that is, the resistor 14 at the highest point of the first turntable 12 mentioned above. The lateral push block 173 is used to push the head of the resistor 14 from the first turntable 12 laterally to a part of the lifting portion 172. The lateral push block 173 can move laterally driven by the driving cylinder 173a.
[0028] like Figure 3As shown, in a preferred embodiment, there are two first turntables 12 arranged side by side, with a gap between the two first turntables 12, and at least a portion of the lifting portion 172 located within the gap. Specifically, the lifting portion 172 may be composed of three parts: a first part 172a for attracting the head of the resistor 14, a second part 172b for attracting the middle portion of the lead wire of the resistor 14, and a third part 172c for attracting the tail portion of the lead wire of the resistor 14. The first part 172a is located on the other side of the first turntable 12 opposite the gap, the second part 172b is located within the gap between the two first turntables 12, and the third part 172c is located between the first turntable 12 and the second turntable 15. In a preferred embodiment, the lifting portion 172 also includes a groove 174 for accommodating the resistor 14 and a magnet 175. The groove 174 is used to accommodate and position the resistor 14, and the magnet 175 is used to attract the lead wire of the resistor 14.
[0029] Pin 171 is located above resistor 14. A movable bracket 171a drives pin 171 to move vertically and horizontally along the length of the lead wire. A transverse pusher 173 is located to one side of the lead wire's tail. Driven by a pneumatic cylinder 173a, this pusher pushes the lead wire of resistor 14, pushing the head of resistor 14 onto the first portion 172a of the lifting portion 172.
[0030] After the resistor 14 moves from the guide channel to the first turntable 12 and is adsorbed to the circumferential surface of the first turntable 12, the first turntable 12 rotates to drive the resistor 14 to move to the highest point mentioned above. Driven by the driving cylinder 11, the lifting portion 172 moves from a position away from the resistor 14 to a position in contact with the resistor 14. The lateral push block 173 pushes the tail of the pin wire of the resistor 14 to push the head of the resistor 14 into the groove 174 of the first part 172a of the lifting portion 172. The lifting portion 172 continues to move upward until the resistor 14 is lifted. The split pin 171 located above the resistor 14 moves downward in a direction perpendicular to the length direction of the pin wire to be inserted between the pin wires of the resistor 14. The insertion of the split pin 171 between the pin wires causes the metal pin wire to deform, such as Figure 5 As shown. The pins 171 inserted between the pins are then moved along the length of the pins to straighten them. Pins 171 are then driven by the drive cylinder 11 to return to their initial position. The resistors 14 are then transported by the conveyor mechanism to the next step for processing.
[0031] like Figure 6 and Figure 7As shown, according to another embodiment, the resistor pin-splitting device of the present invention further includes an elastic pre-stressing mechanism 177, and the elastic pre-stressing mechanism 177 is arranged side by side with the pin-splitting needle 171 along the length direction of the pin wire of the resistor 14. In a specific embodiment, the elastic pre-stressing mechanism 177 is mounted on a movable bracket 171a. The elastic pre-stressing mechanism 177 further includes a pressure rod 177a and a compression spring 177b mounted at the lower end of the pressure rod 177a. The compression spring 177b can apply pressure to the pin wires of the resistor 14 so that the pin wires are arranged horizontally and side by side, so that the pin-splitting needle 171 can be inserted between the pin wires of the resistor 14. When the compression spring 177b contracts, the elastic pre-stressing mechanism 177 will not apply excessive pressure to the pin wires of the resistor 14, thereby avoiding deformation of the pin wires. When the resistor pin-splitting device of the present invention is working, the movable bracket 171a drives the elastic preload mechanism 177 and the pin-splitting needle 171 to move downward toward the resistor 14 at the same time. The elastic preload mechanism 177 first contacts the pin wire of the resistor 14, the compression spring 177b contracts and flattens the two pin wires, and the pin-splitting needle 171 is then inserted between the two pin wires.
