Description

Technical Field

[0001] This utility model relates to the field of diode manufacturing technology, and more specifically, to an automatic ejection device for bending diode leads. Background Technology

[0002] As an important electronic component, diodes often require the excessively long leads to be cut off during the pre-packaging process. To ensure the accuracy of the cutting position, a fixture with a positioning groove is commonly used in production to fix the cylindrical body of the diode. The arc-shaped structure of the positioning groove restricts its position, thereby allowing the leads to extend to a specified length for cutting.

[0003] However, in the existing technology, after the pins are cut off, the operator needs to manually remove the diode from the positioning slot. Since the positioning slot is usually designed to fit tightly with the diode body to ensure positioning accuracy, and the depth of the slot is often greater than the diode radius, it is extremely inconvenient to remove the part by hand. The operator often needs to use additional tools such as tweezers to pry it off, or repeatedly tilt and tap the fixture to remove the part. This not only greatly reduces production efficiency, but also easily scratches the diode surface or causes the cut pins to deform during the operation, affecting product quality and subsequent processes. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic ejection device for bent diode leads, in order to solve the problems mentioned in the background art. After the pins are cut off, the operator needs to manually remove the diode from the positioning slot, which is extremely inconvenient to handle by hand.

[0005] To address the above problems, this utility model aims to provide an automatic diode pin bending ejection device, comprising an assembly block. A positioning groove is formed at the center of the top of the assembly block, and a receiving groove is formed at the bottom of the positioning groove. A top block is slidably mounted inside the receiving groove. An embedded groove is formed at the top of the top block, and a wedge is slidably disposed inside the embedded groove. The upper sidewall of the wedge is inclined. A bottom groove is formed at the bottom of the top block, and an end plate is slidably mounted inside the bottom groove. A connecting rod is vertically fixed to the upper sidewall of the end plate. The upper end of the top plate slides through the bottom groove and is fixedly connected to the lower side wall of the wedge. A first spring is provided between the top side of the end plate and the bottom groove and sleeved on the connecting rod. A lifting mechanism is provided on the lower side of the end plate. The lifting mechanism is used to drive the end plate to move vertically upward. Spring assemblies are provided on both sides of the top block. The spring assemblies are used to push the top block to move vertically downward. When the lifting mechanism drives the end plate to move vertically upward, the top block moves upward against the action of the spring assembly. When the upper side wall of the top block moves above the positioning groove, the end plate drives the wedge to move vertically upward against the elastic force of the first spring.

[0006] As a further improvement to this technical solution, the assembly block is provided with an installation groove that communicates with the storage groove, and the lifting mechanism includes an extension frame that is vertically fixed to the lower end of the end plate, and a roller is rotatably installed at the lower end of the extension frame.

[0007] As a further improvement to this technical solution, a rotating plate is hinged to one end of the bottom side of the mounting groove, and one end of the rotating plate extends to the outside of the mounting groove. The circumferential sidewall of the roller makes rolling contact with the upper sidewall of the rotating plate.

[0008] As a further improvement to this technical solution, guide grooves are provided at the bottom of both sides of the storage groove, and a protrusion is fixedly connected to the top block at the position corresponding to each guide groove. The protrusion is slidably disposed inside the corresponding guide groove.

[0009] As a further improvement to this technical solution, a stop block is fixedly connected to the side wall of the guide groove. When the protrusion moves to a position that contacts the lower side wall of the stop block, the upper side wall of the top block is located above the positioning groove.

[0010] As a further improvement to this technical solution, the spring assembly includes a guide rod fixedly connected to the top side of the guide groove, an end cap fixedly connected to the lower end of the guide rod, and a second spring sleeved on the guide rod between the upper sidewall of the protrusion and the top side of the guide groove. The second spring pushes the protrusion downward so that the lower sidewall of the protrusion contacts the upper sidewall of the end cap.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This diode lead bending automatic ejection device uses a lifting mechanism to push the end plate and connecting rod upwards. First, it moves the top block upwards, smoothly pushing the diode away from the positioning groove. Then, the wedge block continues to move upwards under the action of the connecting rod, and uses its inclined structure to push the diode to slide outwards along the inclined surface. Finally, the diode is completely pushed onto the upper surface of the assembly block, thereby realizing the automatic ejection and pushing of the diode after the lead is cut off. This facilitates the operator to pick up the material with one hand, improving the material picking efficiency and operation convenience. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0015] Please see Figure 1 As shown, the purpose of this embodiment is to provide an automatic diode lead bending ejection device, including an assembly block 1. A positioning groove 11 is provided at the middle position of the top of the assembly block 1. The positioning groove 11 is an arc-shaped groove for positioning a cylindrical diode. This device can be used in conjunction with an external diode lead cutting device. During use, the device is clamped and fixed on the device by the clamping mechanism on the cutting device. The diode is placed in the positioning groove 11 and the two leads of the diode extend out of the positioning groove 11. The positioning groove 11 can accurately position the diode during the lead cutting process, thereby ensuring that the cutting device can accurately remove the excess lead portion.

[0016] To facilitate the removal of the diode from the positioning slot 11 after the pins are cut off, refer to Figures 3-7A storage groove 13 is provided at the bottom of the positioning groove 11. A top block 3 is slidably installed inside the storage groove 13. An embedded groove 31 is provided at the top of the top block 3. A wedge 5 is slidably arranged inside the embedded groove 31. The upper sidewall of the wedge 5 is inclined. In the initial state, the upper sidewall of the top block 3 and the wedge 5 are completely below the bottom surface of the positioning groove 11, which will not interfere with the placement of the diode and ensure positioning accuracy. A bottom groove 33 is provided at the bottom of the top block 3. An end plate 6 is slidably installed inside the bottom groove 33. A connecting rod 61 is vertically fixedly connected to the upper sidewall of the end plate 6. The upper end of the connecting rod 61 slides through the bottom groove 33 and is fixedly connected to the lower sidewall of the wedge 5. A first spring 62 is provided between the top side of the end plate 6 and the bottom groove 33 and sleeved on the connecting rod 61.

[0017] Guide grooves 14 are provided at the bottom of both sides of the storage groove 13. A protrusion 32 is fixedly connected to the top block 3 at the position corresponding to each guide groove 14. The protrusion 32 is slidably disposed inside the corresponding guide groove 14. A stop block 4 is fixedly connected to the side wall of the guide groove 14. At the same time, spring assemblies are provided on both sides of the top block 3. The spring assemblies are used to push the top block 3 to move vertically downward. The structure of the spring assembly is detailed below. The spring assembly includes a guide rod 7 fixedly connected to the top side of the guide groove 14. An end cap 71 is fixedly connected to the lower end of the guide rod 7. A second spring 72 is provided between the upper side wall of the protrusion 32 and the top side of the guide groove 14 and is sleeved on the guide rod 7. The second spring 72 pushes the protrusion 32 to move downward, so that the lower side wall of the protrusion 32 contacts the upper side wall of the end cap 71. The end cap 71 prevents the protrusion 32 from falling out of the guide groove 14.

[0018] It is worth noting that the combined force of the two second springs 72 is designed to be less than that of the first spring 62, so that when the lifting mechanism 2 is activated, it can first overcome the force of the second springs 72 to push the top block 3 upward as a whole, and then compress the first spring 62.

[0019] A lifting mechanism 2 is provided on the lower side of the end plate 6. The lifting mechanism 2 is used to drive the end plate 6 to move vertically upward. When the lifting mechanism 2 drives the end plate 6 to move vertically upward, since the elastic force of the first spring 62 is greater than that of the second spring 72, the end plate 6 will push the top block 3 upward through the first spring 62, thereby lifting the diode in the positioning groove 11 upward. At the same time, the protrusion 32 slides along the guide groove 14, the first spring 62 is gradually compressed, and the top block 3 continues to move upward against the action of the spring assembly. When the protrusion 32 contacts the lower side of the stop block 4, the stop block 4 prevents the protrusion 32 from moving upward, thereby preventing the top block 3, which is fixedly connected to the protrusion 32, from moving upward. At this time, the upper surface of the top block 3 is higher than the positioning groove 11, thereby pushing the diode out of the positioning groove 11.

[0020] As the end plate 6 is further lifted, the distance between it and the top wall of the bottom groove 33 decreases, and the first spring 62 is compressed and contracts. At this time, the end plate 6 overcomes the elastic force of the first spring 62 and pushes the wedge block 5 upward through the connecting rod 61. The wedge block 5 continues to lift the diode and pushes the diode to slide towards the lower side of the slope with the help of the inclined structure at its top, until the diode is pushed to the upper surface of the assembly block 1. At this time, the operator can easily remove the diode from the assembly block 1.

[0021] In addition, the assembly block 1 has a mounting groove 12 that communicates with the storage groove 13. The mounting groove 12 is used to install the lifting mechanism 2. The structure of the lifting mechanism 2 is described in detail below, referring to... Figure 2 The lifting mechanism 2 includes an extension frame 21 that is vertically fixed to the lower end of the end plate 6. A roller 22 is rotatably mounted on the lower end of the extension frame 21. A rotating plate 23 is hinged to one end of the bottom side of the mounting groove 12. One end of the rotating plate 23 extends to the outside of the mounting groove 12. The circumferential sidewall of the roller 22 makes rolling contact with the upper sidewall of the rotating plate 23.

[0022] When the end plate 6 needs to be lifted upward, the operator presses the end of the rotating plate 23 located outside the mounting groove 12 downward, causing the rotating plate 23 to rotate around the hinge axis. The other end of the rotating plate 23 is lifted upward, and the extension frame 21 and the end plate 6 are pushed upward through the roller 22. After the diode is pushed to the upper surface of the assembly block 1, the rotating plate 23 is released. Under the rebound action of the first spring 62 and the second spring 72, the top block 3 and the wedge block 5 are reset to their initial positions, and the lifting mechanism 2 also returns to its original state, without affecting the next use. At this time, the diode is located on the upper side wall of the assembly block 1 and will not fall back into the positioning groove 11. The operator can complete the material picking with one hand, which improves the material picking efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
