Description

Technical Field

[0001] This utility model relates to the field of diode manufacturing technology, specifically to a lead cutting device for producing light-emitting diodes. Background Technology

[0002] LED lead shearing machines are mechanical devices specifically designed for cutting the leads of light-emitting diodes (LEDs). Their core function is to use precision cutters or shearing mechanisms to cut the packaged LED leads to a fixed length and neatly to meet the requirements of subsequent assembly or soldering processes.

[0003] For example, Chinese Patent Application No. 201720926230.X discloses a lead-cutting machine, including a frame, a feeding mechanism, a cutting device, and a collecting device. The feeding mechanism includes a vibrating table mounted on the frame and a vibration generator that vibrates the vibrating table. The vibrating table has a feeding groove extending through its thickness along its length. The cutting device includes a cutting blade mounted below the feeding groove and a driving device that drives the cutting blade. The collecting device includes a receiving box mounted near the end of the feeding groove where the cutting blade is located and a waste recycling box mounted below the cutting blade. A diode to be cut is placed in the feeding groove, with the diode body mounted on both sides of the groove and the leads extending from it. Under the vibration of the vibration generator, the diode moves towards the end where the cutting blade is located. The cutting blade reciprocates under the drive of a cutting cylinder, thereby cutting off the leads below the diode. The cut diode falls into the receiving box, while the cut leads fall into the waste recycling box.

[0004] In the use of lead shearing machines for LED production, the sheared material is usually transferred to a receiving box. However, existing receiving boxes require manual placement and replacement when full. This operation not only requires additional dedicated personnel for replacement, increasing labor costs, but also significantly reduces overall production efficiency due to frequent manual intervention.

[0005] Therefore, it is necessary to redesign and modify the lead cutting device used in LED production to effectively prevent reduced production efficiency and increased labor costs. Summary of the Invention

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a lead cutting device for LED production, which has the advantages of being easy to use and solves the problems of reduced production efficiency and increased labor costs.

[0009] As a preferred embodiment of this invention, a baffle is movably connected to the top of the top plate, and the right side of the baffle is fixedly connected to the left side of the shearing machine. The baffle can prevent the receiving box from moving excessively.

[0010] As a preferred embodiment of this utility model, an extension box is fixedly connected to the front side of the receiving box, and the extension box can prevent material from leaking out when the receiving box is replaced.

[0011] As a preferred embodiment of this invention, the surface of the conveying device is fixedly connected with an anti-slip belt, which can increase the movement stability of the receiving box.

[0012] As a preferred embodiment of this invention, the surface of the receiving box is provided with an arc corner, which can prevent sharp edges from scratching the operator.

[0014] 1. When this utility model is in use, under the action of the conveying mechanism and linkage components, it can automatically collect and transport the light-emitting diodes after the shearing machine has cut them, avoiding the decrease in work efficiency caused by the inability to automatically transport the materials after the shearing machine has cut and collected them, thus giving it the advantage of being easy to use.

[0021] 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.

[0022] like Figures 1 to 4 As shown, the present invention provides a lead cutting device for LED production, including a shearing machine 1, a feeding plate 2 mounted on the top of the shearing machine 1, a conveying mechanism including a conveying device 3 disposed on the left side of the shearing machine 1, a fixed frame 4 fixedly connected to the left side of the shearing machine 1, fixed boxes 5 fixedly connected to the left and right sides of the top of the fixed frame 4, a spring 6 fixedly connected to the bottom of the inner wall of the fixed box 5, a top plate 7 fixedly connected to the top of the spring 6, an extension frame 8 fixedly connected to the front of the fixed frame 4, support frames 9 fixedly connected to the left and right sides of the top of the extension frame 8, a receiving box 10 placed on the top of the top plate 7 and the support frame 9, and a linkage component disposed on the left side of the shearing machine 1.

[0023] refer to Figure 4 The linkage component includes a connecting plate 11 fixedly connected to the front side of the receiving box 10, a flip plate 12 hinged to the front side of the connecting plate 11, a spring plate 13 in contact with the bottom of the flip plate 12, the bottom of the back of the spring plate 13 fixedly connected to the front side of the connecting plate 11, and a linkage plate 14 movably connected to the surface of the flip plate 12, the front side of the linkage plate 14 fixedly connected to the back of the receiving box 10.

[0024] As a technical optimization of this utility model, the hinged flip plate 12 and spring plate 13 of the linkage component are designed to realize the automatic replacement of the receiving box 10 and increase the replacement efficiency of the receiving box 10.

[0025] refer to Figure 3 A baffle 15 is movably connected to the top of the top plate 7. The right side of the baffle 15 is fixedly connected to the left side of the shearing machine 1. The baffle 15 can prevent the receiving box 10 from moving excessively.

[0026] As a technical optimization of this utility model, the movement range of the receiving box 10 is limited by the baffle 15 to prevent it from leaving the working position due to inertia, thereby ensuring the stability and safety of the equipment operation.

[0027] refer to Figure 2 An extension box 16 is fixedly connected to the front side of the receiving box 10. The extension box 16 can prevent material from leaking out when the receiving box 10 is replaced.

[0028] As a technical optimization of this utility model, by extending the box 16 to form an inclined receiving space when replacing the receiving box 10, the material is prevented from scattering, waste is reduced and the working environment is kept clean.

[0029] refer to Figure 1 An anti-slip belt 17 is fixedly connected to the surface of the conveying device 3, which can increase the movement stability of the receiving box 10.

[0030] As a technical optimization of this utility model, the friction between the conveying device 3 and the receiving box 10 is increased by the anti-slip belt 17, which prevents the material from slipping or deviating during transfer, thereby improving the conveying accuracy and efficiency.

[0031] refer to Figure 2 The surface of the receiving box 10 is provided with an arc corner 18, which can prevent sharp edges from scratching the operator.

[0032] As a technical optimization of this utility model, the 18 arc angle design eliminates the sharp parts of the edges of the receiving box 10, reduces the risk of scratches to operators, and meets the requirements of safe production.

[0033] The working principle and usage process of this utility model: In use, this device is mainly used for the automated receiving and conveying of materials after shearing. During operation, after the shearing machine 1 cuts the material, the material is guided to the receiving box 10 on the left side by the top conveying plate 2. Then, the top plate 7 supported by the spring 6 supports the receiving box 10. When the material in the receiving box 10 accumulates to a certain weight, it presses down on the top plate 7 and compresses the spring 6, triggering the conveying device 3 and the linkage assembly. At this time, the bottom of the receiving box 10 contacts the top of the conveying device 3, causing the conveying device 3 to move the receiving box 10 backward (the fully loaded receiving box 10 moves downward due to the pressure on the top plate 7, thus overcoming the obstruction of the baffle 15). The flipping plate 12 on the front side of the connecting plate 11 is abutted by the spring plate 13, which drives the linkage plate 14 to pull the front receiving box 10 backward synchronously until the front receiving box 10 without material reaches the receiving position (because the front receiving box 10 is blocked by the baffle 15, the flipping plate 12 is squeezed and flipped by the linkage plate 14, thus detaching the connection between the front and rear receiving boxes 10). At this time, the receiving box 10 (without material) is blocked by the baffle 15 and stays in the receiving position. The anti-slip belt 17 ensures stable conveying, while the baffle 15 and the extension box 16 prevent excessive displacement of the receiving box 10 and material leakage, respectively. The 18° arc design ensures operational safety, enabling efficient and safe material transfer. It avoids the reduced work efficiency caused by the inability to automatically transport materials after shearing and collection, thus making it easy to use.

[0034] In summary, when this utility model is used, under the action of the conveying mechanism and linkage components, it can automatically collect and transport the light-emitting diodes cut by the shearing machine 1, avoiding the decrease in work efficiency caused by the inability to automatically transport the materials after shearing and collection by the shearing machine 1, thus giving it the advantage of being easy to use.
