Description

Technical Field

[0001] This utility model belongs to the field of diode processing technology, and more specifically, it relates to a pin processing device for diode processing. Background Technology

[0002] As a fundamental component in electronic circuits, the quality of diode lead processing directly affects the accuracy of subsequent soldering and assembly, as well as the circuit's conductivity. Therefore, lead trimming is one of the key processes in diode manufacturing.

[0003] Traditional diode processing relies heavily on manual feeding and positioning. Operators must manually fix individual diodes or diodes before cutting them, resulting in low efficiency, difficulty in meeting mass production needs, and frequent human errors leading to inconsistent lead lengths and uneven cuts, affecting the diodes' subsequent use. To address these shortcomings, there is an urgent need for a lead processing device capable of multi-dimensional diode positioning, automated and precise feeding, and cutting to improve the quality and efficiency of diode manufacturing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pin processing device for diode processing, which is achieved by the following specific technical means:

[0005] A pin processing device for diode fabrication includes a base plate and a diode. Two support arms are fixedly mounted on the upper end of the base plate, and a rotating shaft is rotatably mounted between the two support arms. A drive device for driving the rotating shaft is fixedly mounted on the base plate. Two turntables are fixedly mounted on the rotating shaft. Each turntable has a plurality of notches equidistantly spaced on its surface. A cutting assembly is provided between the two support arms. The cutting assembly includes a fixed plate and a connecting plate. Cutting shears are fixedly mounted on both sides of the bottom end of the connecting plate. An electric telescopic rod is fixedly mounted on the upper end of the fixed plate. The bottom end of the electric telescopic rod is fixedly connected to the middle of the upper end of the connecting plate. A limit assembly is provided on each support arm. The limit assembly includes a limit sleeve. The surface of the limit sleeve has a receiving groove, and the edge of the diode movably passes through the receiving groove.

[0006] Furthermore, guide rods are fixedly installed on both sides of the upper end of the connecting plate, and each guide rod movably passes through the fixed plate.

[0007] Furthermore, two guide rods are fixedly installed on the outer end of the limiting sleeve. The two guide rods movably pass through the support arm. An electric telescopic rod is fixedly installed on the support arm. The telescopic rod of the electric telescopic rod is fixedly connected to the limiting sleeve.

[0008] Furthermore, a support plate is fixedly installed on the upper end of the base plate, the diode is placed on the support plate, and a groove adapted to the diode is opened on the upper surface of the diode, and the diode can move along the length direction of the groove.

[0009] Furthermore, two support arms are fixedly installed on both sides of the upper end of the base plate, with the two support arms located between the two support arms, and the two cutting shears located above the two support arms respectively.

[0010] Furthermore, the diode comprises a plurality of equally spaced diodes, and the gap between each adjacent notch is adapted to the gap between each adjacent diode.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] I. This diode processing pin handling device, through the matching design of the turntable notch and the diode gap, combined with the intermittent conveying of the drive equipment, realizes automatic step-by-step feeding of the diode. It can complete the continuous cutting of the entire row of pins without manual intervention, improving cutting efficiency. The notch and the diode pins engage to ensure no deviation in the conveying direction. The limit sleeve is pushed by the electric telescopic rod two to clamp the two sides of the diode. Combined with the groove design of the support plate, it forms multi-directional constraints in the vertical and horizontal directions, completely avoiding positional deviations during conveying or cutting. The cutting blade is guided downward by the guide rod one, with a precise trajectory and no shaking. With the bottom support of the support arm two, it prevents the pin from bending under force and ensures the flatness of the cut. The electric telescopic rod one drives the cutting blade to move synchronously, and the pins on both sides are formed in one go.

[0013] Second, after a single cut is completed, the cutter automatically resets, and the turntable continues to drive the diode to transport the next diode to be processed, realizing the "transport-cutting-reset" cycle operation. There is no need to frequently stop the machine to reload, which is suitable for batch processing of diodes. At the same time, the control logic of each component is simple, and the operator only needs to complete the initial loading to realize the automated operation of the device.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a pin processing device for diode processing, including a base plate 1 and a diode 5. Two support arms 11 are fixedly installed on the upper end of the base plate 1, and a rotating shaft 21 is rotatably installed between the two support arms 11. A driving device 2 for driving the rotating shaft 21 is fixedly installed on the base plate 1. Two turntables 3 are fixedly installed on the rotating shaft 21. Each turntable 3 has a number of notches 31 equidistantly opened on its surface. A cutting assembly is provided between the two support arms 11. The cutting assembly includes a fixed plate 6 and a connecting plate 62. Cutting shears 63 are fixedly installed on both sides of the bottom end of the connecting plate 62. An electric telescopic rod 61 is fixedly installed on the upper end of the fixed plate 6. The bottom end of the electric telescopic rod 61 is fixedly connected to the middle of the upper end of the connecting plate 62. A limit assembly is provided on each support arm 11. The limit assembly includes a limit sleeve 8. The surface of the limit sleeve 8 has a receiving groove 81. The edge of the diode 5 moves through the receiving groove 81.

[0027] Guide rods 64 are fixedly installed on both sides of the upper end of the connecting plate 62. Each guide rod 64 moves through the fixed plate 6, which can limit the left and right swaying of the connecting plate 62 when it moves down and ensure the stability of the movement trajectory.

[0028] Two guide rods 82 are fixedly installed on the outer end of the limiting sleeve 8. The two guide rods 82 movably pass through the support arm 11. An electric telescopic rod 7 is fixedly installed on the support arm 11. The telescopic rod of the electric telescopic rod 7 is fixedly connected to the limiting sleeve 8. The guide rods 82 on the outer side of the limiting sleeve 8 movably pass through the support arm 11, which can ensure that the limiting sleeve 8 does not deviate when it moves and is more stable.

[0029] A support plate 4 is fixedly installed on the upper end of the base plate 1. The diode 5 is placed on the support plate 4. A groove adapted to the diode 5 is opened on the upper surface of the diode 5. The diode 5 can move along the length of the groove.

[0030] Support arms 2 12 are fixedly installed on both sides of the upper end of the base plate 1. The two support arms 2 12 are located between the two support arms 11. The two cutting shears 63 are located above the two support arms 2 12 respectively. The support arms 2 12 can help support the diode and prevent it from deforming under force during cutting.

[0031] Diode 5 comprises multiple equally spaced diodes, and the gap between each adjacent slot 31 is adapted to the gap between each adjacent diode.

[0032] The working principle of this embodiment:

[0033] Step 1: Place the "diode 5", which contains multiple equally spaced diodes, on the support plate 4 at the top of the base plate 1. The support plate 4 has grooves on its surface that are compatible with the diode 5, which can restrict the diode from moving up and down while allowing it to move smoothly along the length of the groove. Subsequently, the two diodes at the very front of diode 5 are respectively inserted into the notches 31 on the surfaces of the two turntables 3 (the gap between adjacent notches 31 is perfectly matched with the gap between adjacent diodes). Through the snapping action of the notches 31, the initial positioning of the diode conveying direction is achieved, preventing deviation during conveying. The electric telescopic rods 7 on the two support arms 11 are activated, and their telescopic rods will push the limiting sleeves 8 towards the diode 5 (the guide rods 82 on the outside of the limiting sleeves 8 can move through the support arms 11 to ensure that the limiting sleeves 8 do not deviate and are more stable during movement). When the two limiting sleeves 8 approach each other to the designated position, the receiving grooves 81 on their surfaces will fit precisely on both sides of the diode 5, forming multi-dimensional limiting in the upper, lower, left, and right directions, completely preventing the diode from falling off or deviating during subsequent conveying. The drive device 2 on the base plate 1 is activated, and the drive device 2 drives the rotating shaft 21 (rotatably installed between the two support arms 11) to rotate. The rotating shaft 21 synchronously drives the two turntables 3 fixed on it to rotate. As the diode front end is inserted into the notch 31, the circumferential motion of the turntable 3 can smoothly drive the diode 5 to move precisely along the groove of the support plate 4 towards the cutting assembly located between the two support arms 11.

[0034] Step 2: When the foremost single diode in diode 5 is conveyed by turntable 3 to directly below the cutting assembly (above the two support arms 12, which can assist in supporting the diode and prevent deformation during cutting), the conveying action pauses, the device enters the cutting state, and the electric telescopic rod 61 in the cutting assembly (fixed to the upper end of the fixed plate 6) is activated. Its telescopic rod extends downwards, driving the connecting plate 62, which is fixedly connected to it, to move downwards synchronously. The guide rods 64 on both sides of the upper end of the connecting plate 62 move through the fixed plate 6, limiting the left and right swaying of the connecting plate 62 during downward movement and ensuring... With a stable movement trajectory, the two cutting shears 63 fixed at the bottom of the connecting plate 62 move down synchronously with the connecting plate 62 to cut the pins on both sides of the single diode below, completing one pin processing. After a single cut is completed, the telescopic rod of the electric telescopic rod 61 retracts, driving the cutting shears 63 to reset. At the same time, the drive device 2 starts again, and the turntable 3 continues to drive the diode 5 forward by one "diode spacing", so that the next diode to be processed reaches the cutting position. The "positioning-cutting-resetting" action is repeated to realize the continuous and automated processing of the diode 5 pins.
