Description

Technical Field

[0001] This utility model relates to the field of LED manufacturing equipment technology, and in particular to a lead cutting device for the production of light-emitting diodes. Background Technology

[0002] In the packaging and assembly of light-emitting diodes (LEDs), lead trimming is one of the key process steps. LED components typically achieve electrical connection with external circuits through leads. After soldering or other assembly processes, the lead lengths need to be trimmed according to product specifications to meet subsequent assembly, installation, and appearance requirements. The quality of lead trimming directly affects the electrical performance, assembly accuracy, and overall appearance consistency of LED products. Therefore, high requirements are placed on the precision, efficiency, and stability of the trimming equipment.

[0003] Patent CN215467779U discloses a diode pin cutting device. This device includes a presser foot base, a presser foot cylinder, a cutter slide, and a cutter assembly. A structure with multiple diode pin groups is placed on a platform on the presser foot base. The presser foot cylinder is activated, causing the presser foot to press down and fix the pin heads. Then, an external cylinder pushes a pressure plate, causing the cutter slide to move downwards, thereby driving the cutter to cut the pins. After cutting, the cylinder resets, and the cutter slide resets using an elastic element, ready for the next cutting action. Although this device achieves basic automated cutting functionality, it still has some shortcomings in practical applications. The fixed installation position of the cutter makes it impossible to adjust the cutting length according to different product specifications, limiting its versatility in various LED product models.

[0004] Therefore, there is an urgent need to provide a lead cutting device for LED production that can adjust the cutting length according to different product specifications. Utility Model Content

[0005] In order to overcome the shortcomings of existing lead cutting devices, such as fixed cutting position, inability to flexibly adjust cutting length according to product specifications, and poor applicability, this utility model provides a lead cutting device for LED production that can adjust the cutting length according to different product specifications.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a lead cutting device for LED production, comprising a support frame, a chain conveyor belt mounted on the support frame, a servo motor mounted on one side of the support frame to drive the chain conveyor belt, several card holders evenly spaced along the length of the chain conveyor belt, sponge pads inside the card holders, symmetrically distributed support seats fixed to the rear of the support frame, a sliding block mounted on the top of the support seat, a cutter mounted on the top of the sliding block, and a rotatable one-way screw mounted on the support seat, one end of the one-way screw threadedly connected to the corresponding sliding block, and the other end extending out of the support seat and connected to an adjustment knob.

[0007] As a further preferred embodiment, the adjustment knob is covered with a rubber anti-slip sleeve.

[0008] As a further preferred embodiment, a support plate is fixedly connected to the support base, the support plate is located on both sides of the chain conveyor belt, a connecting frame is fixedly connected to the support frame, a pressure plate is fixedly connected to the top of the connecting frame, and the pressure plate is located above the chain conveyor belt.

[0009] As a further preferred embodiment, a baffle is fixedly connected to one end of the support plate near the cutter.

[0010] As a further preferred embodiment, a stabilizing plate is fixedly connected to the rear of the support frame, a stripping rod is fixedly connected to the stabilizing plate, and an inclined guide plate is fixedly connected to the stripping rod.

[0011] As a further preferred embodiment, the servo motor is provided with a protective shell.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The device adopts a servo motor to drive the chain conveyor belt and is equipped with an adjustable cutter structure. The lateral position of the cutter can be precisely adjusted by rotating the adjustment knob, which can adapt to the pin cutting requirements of different types of light-emitting diodes and improve the versatility and flexibility of the equipment.

[0013] 2. Support plates and pressure plates are respectively installed at the conveying station and the cutting station. The support plates support the LED pins to prevent them from bending due to their own weight or slight collisions during the conveying process, while the pressure plates are used to press the LED body to prevent the device from shifting due to vibration or impact during the cutting process, thereby improving the cutting quality and stability.

[0014] 3. By setting up a stripping mechanism consisting of a stripping rod and a guide plate, the LED components are automatically lifted from the card holder and orderly exported through the guide plate after cutting, avoiding manual handling and reducing labor intensity.

Detailed Implementation

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1: Please refer to Figures 1-4A lead-cutting device for LED production includes a support frame 1, a chain conveyor belt 2 mounted on the support frame 1, a servo motor 3 mounted on the right side of the support frame 1 to drive the chain conveyor belt 2, a protective shell 19 for dustproof, waterproof and mechanical protection of the servo motor 3, several clamping seats 4 evenly spaced along the length of the chain conveyor belt 2, and sponge pads 5 inside the clamping seats 4 to fix and cushion the LED body to prevent damage from vibration or collision during transport, and symmetrically distributed support bases 6 fixed to the rear of the support frame 1, with a sliding block 7 on the top of the support base 6, and a mounting plate on the top of the sliding block 7. A cutter 8 is provided, which is vertically downward and used to cut the pins of LEDs conveyed to a designated position. A one-way screw 9 is rotatably mounted on the support base 6. One end of the one-way screw 9 is threadedly connected to the corresponding moving block 7, and the other end extends out of the support base 6 and is connected to an adjustment knob 10. By rotating the adjustment knob 10, the one-way screw 9 is driven to rotate, thereby driving the moving block 7 to slide horizontally on the support base 6, realizing the lateral position adjustment of the cutter 8 relative to the chain conveyor belt 2 to adapt to the cutting requirements of LED pins of different sizes. The adjustment knob 10 is covered with a rubber anti-slip sleeve 11 to enhance the operator's feel and friction when rotating and adjusting, prevent slippage, and improve adjustment accuracy and safety.

[0024] When using this device, the LED to be cut is placed in the holder 4 on the chain conveyor belt 2. The holder 4 is equipped with a sponge pad 5, which can effectively buffer vibration and also play a role in positioning and fixing, preventing the LED from shifting or being damaged during the conveying process. Then, the servo motor 3 is started to drive the chain conveyor belt 2 to transport the holder 4 containing the LED to the cutting station. Before cutting, the one-way screw 9 is adjusted by rotating the adjustment knob 10 according to the pin specifications of the current LED, so that the moving block 7 moves horizontally along the top slide rail of the support base 6, thereby driving the cutter 8 to move laterally so that it is aligned with the cutting position of the pin, realizing flexible adjustment of the cutting length. When the LED reaches the cutting position, the cutter 8 starts to cut the pin. After the cutting is completed, the chain conveyor belt 2 continues to run, sending the processed LED to the next process.

[0025] Example 2: Based on Example 1, please refer to... Figure 5A support plate 12 is fixedly connected to the support base 6. The support plate 12 is located on the left and right sides of the chain conveyor belt 2. It is used to provide auxiliary support for the pins of the light-emitting diode during the conveying process to prevent the pins from being deformed or broken by force. A connecting frame 13 is fixedly connected to the support frame 1. A pressure plate 14 is fixedly connected to the top of the connecting frame 13. The pressure plate 14 is located above the chain conveyor belt 2 and is used to apply downward pressure to the light-emitting diode to prevent the device from shifting or shaking due to vibration or cutting impact during the cutting process. A baffle 15 is fixedly connected to one end of the support plate 12 near the cutter 8 to block the metal debris generated during cutting from splashing and falling into the cutter 8.

[0026] During the process of the chain conveyor belt 2 transporting the light-emitting diode to the cutting station, the support plate 12 supports the two ends of the light-emitting diode from below. This design effectively prevents the pins from bending due to their own weight or slight collisions during the transport process. When the light-emitting diode is transported to the cutting station, that is, directly below the pressure plate 14, the pressure plate 14 presses the surface of the light-emitting diode to form a stable clamping state, preventing the device from being displaced due to vibration or cutting impact during the cutting process.

[0027] Please see Figure 6 A stabilizing plate 16 is fixedly connected to the rear of the support frame 1. A stripping rod 17 is fixedly connected to the stabilizing plate 16. The stripping rod 17 is vertically arranged and corresponds to the position of the card seat 4 on the chain conveyor belt 2. An inclined guide plate 18 is fixedly connected to the stripping rod 17 to guide the lifted light-emitting diodes to the unloading area or collection container in a set direction, so as to realize automatic stripping and orderly discharge.

[0028] After the LED's leads are cut, the chain conveyor belt 2 transports it to the unloading station. At this time, the LED moves with the holder 4 to the front of the unloading rod 17. The unloading rod 17 presses against the bottom edge of the LED from below. As the conveyor belt continues to run, the LED is subjected to the combined action of lateral thrust and upward lifting force, thus detaching from the holder 4. After the LED is lifted, the guide plate 18 receives the LED with its inclined surface and guides it to slide along a predetermined path into the unloading trough, collection box, or subsequent process conveyor belt, avoiding manual intervention in picking up parts and improving the degree of automation and production efficiency.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
