Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a diode welding processing fixture. Background Technology

[0002] A diode is a two-terminal electronic device built from semiconductor materials. Its core structure consists of a PN junction formed by doping P-type and N-type semiconductors. As a fundamental component of electronic circuits, diodes utilize the unidirectional conductivity of the PN junction to achieve unidirectional current conduction and reverse blocking, providing functions such as rectification, switching, voltage regulation, and light emission. Early diodes used point-contact structures (such as germanium crystal diodes). With the development of semiconductor technology, they have gradually evolved into various forms such as junction diodes, Schottky diodes, Zener diodes, and light-emitting diodes (LEDs), and are widely used in power conversion, signal modulation, photoelectric conversion, and high-frequency circuits.

[0003] In the existing technology, diodes need to be soldered to wires during the soldering process. Currently, diode clamps usually only hold a row of diodes, and then one end of the wire is brought close to the diode pin and soldered. After a row of diodes is soldered, the diodes need to be removed from the clamp and the diodes to be soldered need to be re-clamped. This process is time-consuming and labor-intensive, resulting in low efficiency of diode soldering. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that, during the diode welding process, diodes need to be welded to wires. Currently, diode clamps usually only clamp a row of diodes, then one end of the wire is brought close to the diode pin and welded. After the row of diodes is welded, the diodes need to be removed from the clamp and the diodes to be welded need to be clamped again. This process is time-consuming and labor-intensive, resulting in low efficiency in diode welding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a diode welding processing fixture, comprising: a base, and further comprising:

[0006] Two fixed plates are symmetrically fixedly connected to the top of the base. A rotating rod is rotatably connected to one side of the two fixed plates. Two connecting brackets are symmetrically fixedly connected to the outer surface of the rotating rod. A circular tube is fixedly connected to the outer surface of the two connecting brackets. Multiple circular holes are equidistantly arranged in a circular array on the outer surface of the circular tube. An elastic sponge ring is fixedly connected to the inner wall of the circular holes. A motor is fixedly connected to one side of one of the fixed plates. The output end of the motor is fixedly connected to one end of the rotating rod. A wire plate one is provided on the top of the base. A wire plate two is movably connected to one side of the wire plate one via a hinge.

[0007] Preferably, the top of the base has two symmetrical sliding grooves, and the sliding grooves are slidably connected to sliders, both of which are fixedly connected to the wire plate.

[0008] Preferably, the top of the line plate is provided with a plurality of semi-circular grooves at equal intervals, and an arc-shaped elastic sponge is fixedly connected to the inner wall of the semi-circular groove.

[0009] Preferably, the bottom of the second wire plate is provided with a plurality of semi-circular grooves at equal intervals, the inner wall of the semi-circular grooves is fixedly connected with an arc-shaped elastic sponge, the width of the second wire plate is smaller than the width of the first wire plate, and the top of the second wire plate is fixedly connected with a handle.

[0010] Preferably, a magnet block 1 is fixedly connected to one side of the first wire plate, and a magnet block 2 is fixedly connected to one side of the second wire plate, wherein the first magnet block and the second magnet block are magnetically attracted to each other.

[0011] Preferably, a fixing block is fixedly connected to the top of the base, and an electric telescopic rod is fixedly connected to one side of the fixing block. The electric telescopic rod is fixedly connected to the line plate.

[0012] Preferably, the top of the base has a square groove, and the outer surface of the round tube is movably disposed inside the square groove.

[0013] Preferably, a limiting tube is fixedly connected to one side of each of the two connecting brackets.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model involves inserting a diode into a circular hole, causing the diode to press against an elastic sponge ring and be inserted into the ring. The elastic sponge ring then applies a counterforce to the diode, clamping and fixing it in place. A controller starts a motor, causing its output shaft to rotate a rotating rod, simultaneously rotating the connecting frame and the circular tube at an appropriate angle. This allows another row of pre-inserted diodes to rotate into the semi-circular groove, enabling rapid soldering of another set of diodes. This process is time-saving and labor-saving, thus improving the efficiency of diode soldering.

[0016] 2. This utility model uses a controller to activate the electric telescopic rod, causing it to retract. This retraction moves the first and second wire plates away from the circular tube, simultaneously causing the slider to slide inward along the groove. The elastic force of the first and second arc-shaped elastic sponges is greater than that of the elastic sponge ring. A pulling force can be applied to the diode through a wire, pulling the diode out of the elastic sponge ring in the circular hole. This allows for the automatic removal of a row of diodes at the same time, simplifying the operation and improving the convenience of the device. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figure 1-4As shown, this utility model provides a diode welding processing fixture, including: a base 1, and two fixing plates 2, which are symmetrically fixedly connected to the top of the base 1. A rotating rod 201 is rotatably connected to the opposite side of the two fixing plates 2. Two connecting brackets 203 are symmetrically fixedly connected to the outer surface of the rotating rod 201. A circular tube 204 is fixedly connected to the outer surface of the two connecting brackets 203. A plurality of circular holes 205 are equidistantly arranged in a circular array on the outer surface of the circular tube 204. An elastic sponge ring 206 is fixedly connected to the inner wall of the circular hole 205. A motor 202 is fixedly connected to one side of one of the fixing plates 2. The output end of the motor 202 is fixedly connected to one end of the rotating rod 201. A wire plate 302 is provided on the top of the base 1. A wire plate 303 is movably connected to one side of the wire plate 302 through a hinge.

[0026] Furthermore, such as Figure 1-4 As shown, two sliding grooves 102 are symmetrically opened on the top of the base 1. A slider 304 is slidably connected inside the sliding groove 102. Both sliders 304 are fixedly connected to the wire plate 302. With the above arrangement, the wire plate 302 can be supported by the sliders 304. When the wire plate 302 moves to one side, the sliders 304 can slide to one side along the inside of the sliding groove 102.

[0027] Furthermore, such as Figure 1-4 As shown, the top of the wire plate 302 is provided with multiple semi-circular grooves 305 at equal intervals. The inner wall of the semi-circular grooves 305 is fixedly connected with an arc-shaped elastic sponge 306. With the cooperation of the semi-circular grooves 305 and the arc-shaped elastic sponge 306, it is convenient to arrange the wires.

[0028] Furthermore, such as Figure 1-4 As shown, multiple semi-circular grooves 307 are equidistantly provided on the bottom of the second wire plate 303. An arc-shaped elastic sponge 308 is fixedly connected to the inner wall of the semi-circular groove 307. The width of the second wire plate 303 is smaller than the width of the first wire plate 302. A handle is fixedly connected to the top of the second wire plate 303. The semi-circular grooves 307 and the arc-shaped elastic sponge 308 facilitate the insertion of wires. The handle facilitates the pulling of the second wire plate 303. The wires can be squeezed under the elastic force of the semi-circular grooves 307.

[0029] Furthermore, such as Figure 1-4 As shown, a magnet block 309 is fixedly connected to one side of wire plate 302, and a magnet block 310 is fixedly connected to one side of wire plate 303. The magnet block 309 and the magnet block 310 are magnetically attracted to each other. Under the interaction force of the magnet block 309 and the magnet block 310, when the magnet block 309 and the magnet block 310 are attracted together, the wire plate 302 and the wire plate 303 can be kept in a relatively fixed state.

[0030] Furthermore, such as Figure 1-4 As shown, a fixing block 3 is fixedly connected to the top of the base 1, and an electric telescopic rod 301 is fixedly connected to one side of the fixing block 3. The electric telescopic rod 301 is fixedly connected to the line plate 302. The electric telescopic rod 301 is started by the controller to extend, which can drive the line plate 302 to move to one side.

[0031] Furthermore, such as Figure 1-4 As shown, a square groove 101 is provided on the top of the base 1, and the outer surface of the round tube 204 is movably disposed inside the square groove 101. The square groove 101 is provided to prevent the diode from contacting the base 1.

[0032] Furthermore, such as Figure 1-4 As shown, a limiting tube 207 is fixedly connected to one side of the two connecting brackets 203. The limiting tube 207 is used to limit the diodes, so that the exposed length of multiple diodes is the same.

[0033] Working principle: In use, by inserting the diode into the circular hole 205, the diode is squeezed against the elastic sponge ring 206, causing the diode to be inserted into the elastic sponge ring 206. Under the elastic force of the elastic sponge ring 206, a reverse force is applied to the diode, clamping and fixing it. Then, by holding the handle and pulling the second wire plate 303 upward, the first magnet 309 and the second magnet 310 are separated, causing the second wire plate 303 to rotate upward. At this time, the wire can be placed on the arc-shaped elastic sponge 306 in the semi-circular groove 305, so that the soldering part is exposed, exceeding the width of the second wire plate 303. Finally, the second wire plate 303 is placed over the first wire plate 302. Above, the curved elastic sponge 308 is pressed against the top of the wire. Through the elastic force of the curved elastic sponges 306 and 308, the wire is clamped and fixed, and magnets 309 and 310 are attracted together, keeping wire plates 302 and 303 relatively fixed. Then, the controller starts the electric telescopic rod 301, extending and pushing wire plates 302 and 303 towards the circular tube 204. Simultaneously, the slider 304 slides to one side along the inside of the groove 102, moving the wire to the appropriate position. Finally, the controller starts the motor 202, causing its output device to drive the rotating rod 201 to rotate. The synchronous rotation of the connecting frame 203 and the circular tube 204 causes the diode to rotate into the semi-circular groove 305 and contact the exposed wire. Then, a welding device welds the diode and the wire. Once welding is complete and the solder has solidified, the controller activates the electric telescopic rod 301, causing it to retract. This moves the wire plate 302 and wire plate 303 away from the circular tube 204, simultaneously causing the slider 304 to slide inward along the groove 102. The elastic force of the arc-shaped elastic sponge 306 and arc-shaped elastic sponge 308 is greater than that of the elastic sponge ring 206, allowing a pulling force to be applied to the diode through the wire, thus elastically dislodging the diode from the circular hole 205. Pulling out the inner part of the ring 206 allows for the automatic removal of a row of diodes simultaneously, simplifying the operation and improving the convenience of the device. Then, the second wire board 303 is opened to remove the soldered diodes and wires. The first wire board 302 and the second wire board 303 are then returned to their soldering positions. The controller starts the motor 202 again, causing its output shaft to drive the rotating rod 201 to rotate, simultaneously rotating the connecting bracket 203 and the round tube 204 at an appropriate angle. This allows the other row of inserted diodes to rotate into the semi-circular slot 305, enabling rapid soldering of another set of diodes. This process is time-saving and labor-saving, thus improving the efficiency of diode soldering.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
