Description

Technical Field

[0001] This invention relates to the field of LED copper strip processing technology, specifically to a copper strip correction device for an LED copper strip unwinding machine. Background Technology

[0002] LED copper strip is a copper foil strip containing LED chips, commonly used in indoor and outdoor decorative lighting, advertising signage, and architectural outline lighting. LED copper strip typically consists of a copper foil substrate, LED chips, encapsulation materials, and wires. After production, LED copper strip is usually stored in rolls. When needed, an LED copper strip unwinding machine is typically used to unwind it. However, during the unwinding process, the LED copper strip is prone to deviation, leading to edge damage, wrinkles on thinner strips, and surface abrasions, severely affecting product quality. Therefore, a copper strip correction device is required in the LED copper strip unwinding machine during the unwinding process.

[0003] The copper strip alignment device of the LED copper strip unwinding machine is a device used to ensure the smooth unwinding of the copper strip and avoid skewing or tangling. In the traditional copper strip alignment device of the LED copper strip unwinding machine, there may be a situation where it is not possible to correct the alignment of different models of LED copper strip. Summary of the Invention

[0006] Preferably, the second rotating wheel has a second sliding groove on its circumferential surface, and a fixing block is fixedly connected to the upper surface of the rack, the fixing block being slidably connected to the inner wall of the second sliding groove.

[0007] Preferably, a stop block is fixedly connected to the outer wall of the rotating shaft, and a fixing hole is provided inside the first rotating wheel.

[0008] Preferably, a third motor is fixedly connected to the inner wall of the fixing hole, and a first belt pulley is fixedly connected to the output end of the third motor, with the outer wall of the first belt pulley tangent to the outer wall of the first rotating wheel.

[0009] Preferably, a belt is rotatably connected to the inner wall of the first belt pulley, a second belt pulley is rotatably connected to the inner wall of the belt, the outer wall of the second belt pulley is tangent to the outer wall of the first pulley, and a rotating column is fixedly connected to the outer wall of the second belt pulley.

[0010] Preferably, the first rotating wheel has a first rotating hole inside, and the inner wall of the first rotating hole is slidably connected to the outer wall of the rotating column.

[0011] Preferably, the second rotating wheel has a second rotating hole inside, and the inner wall of the second rotating hole is rotatably connected to the outer wall of the rotating column.

[0012] Preferably, a first connecting column is fixedly connected to the outer wall of the first support column, a support block is fixedly connected to the outer wall of the first connecting column, and the inner wall of the support block is slidably connected to the outer wall of the first rotating wheel.

[0013] Preferably, a second support plate is fixedly connected to the upper surface of the base, a sleeve is fixedly connected to the upper surface of the second support plate, the inner wall of the sleeve is slidably connected to the outer wall of the rack, and a baffle is fixedly connected to the left side of the upper surface of the base.

[0014] Preferably, a second pillar is fixedly connected to the right side of the front end of the upper surface of the base, a second connecting pillar is fixedly connected to the outer wall of the second pillar, and a second fixing pillar is fixedly connected to the outer wall of the second connecting pillar.

[0015] Working Principle: When this device is needed, the LED copper strip to be unwound is first attached to the second fixed post on the outer wall of the second connecting post of the second support column. One end of the LED copper strip is placed on the outer wall of the rotating column. The second motor on the outer wall of the first support plate on the upper surface of the base is started. The second motor drives the gear at its output end to rotate. When the gear rotates, it drives the rack at its tooth end to move. The rack slides through the first fixed post on the outer wall of the bracket on its upper surface, along the inner wall of the first sliding groove of the second rotating wheel section. This causes the second rotating wheel to slide through the second slot on the outer wall of the rotating shaft. By changing the distance between the first and second rotating wheels, it can adapt to the use of different types of LED copper strips, preventing them from malfunctioning during operation. If a misalignment occurs during the process, the third motor inside the fixing hole of the first rotating wheel is activated, driving the first belt pulley at its output end to rotate. When the first belt pulley rotates, the belt on its inner wall drives the second belt pulley to rotate on the outer wall of the first rotating wheel. The rotation of the second belt pulley drives the rotating column on its outer wall to rotate, causing the inner walls of the first and second rotating holes inside the first and second rotating wheels to rotate, thus unwinding the LED copper strip. When there is too much LED copper strip on the outer wall of the rotating column, the first motor on the outer wall of the first support column is activated, driving the rotating shaft at its output end to rotate. This, through the first slot, drives the first rotating wheel to rotate along the inner wall of the support block on the outer wall of the first connecting column. The second slot drives the second rotating wheel through the cut... The first sliding groove on the outer wall of the bracket rotates on the outer wall of the first fixed column. The bracket on the upper surface of the rack slides through the first fixed column on its outer wall on the inner wall of the first sliding groove, which allows the second rotating wheel to rotate easily while supporting it. The second sliding groove on the circumferential surface of the second rotating wheel slides on the outer wall of the fixed block on the upper surface of the rack, which can prevent the second rotating wheel from shifting during operation. After the work is completed, the second motor on the outer wall of the first support plate is started to drive the gear at its output end to rotate in the opposite direction, causing the rack on its outer wall to slide towards the inner wall of the sleeve on the upper surface of the second support plate on the base. Through the first fixed column on the outer wall of the bracket on the upper surface of the rack sliding on the inner wall of the first sliding groove of the second rotating wheel section, it drives the second rotating wheel to rotate. The second rotating wheel slides on the outer wall of the rotating shaft through the internal second slot, causing the second rotating hole inside the second rotating wheel to disengage from the outer wall of the rotating column. This allows for rapid unloading of the LED copper strip from the outer wall of the rotating column. The baffle on the left side of the upper surface of the base limits the rack, preventing it from disengaging from the outer wall of the gear. The stop on the outer wall of the rotating shaft prevents the second rotating wheel from disengaging from the outer wall of the rotating shaft through the second slot, thus preventing damage to the device during operation. This device can be used for different types of LED copper strips and can also quickly replace the unwinding structure during operation, improving its work efficiency. Furthermore, it allows for rapid unloading of the LED copper strip after unwinding.

[0016] This invention provides a copper strip alignment device for an LED copper strip unwinding machine. It has the following beneficial effects:

[0017] 1. In this invention, when the second motor drives the gear to rotate, it drives the rack to work. The rack drives the second rotating wheel to slide on the outer wall of the rotating shaft through the second slot via the first fixed post on the inner wall of the first sliding groove, so that the first rotating wheel and the second rotating wheel are close together, which can achieve the correction work for different types of LED copper strips.

[0018] 2. The present invention uses a first motor to drive its rotating shaft to rotate, a first slot to drive the first rotating wheel to rotate, and a second slot to drive the second rotating wheel to rotate. When the first and second rotating wheels rotate, they drive the rotating column to move, so that the rotating column can be quickly replaced without affecting the work, thereby improving the efficiency of unwinding.

[0019] 3. In this invention, the rack moves towards the inner wall of the sleeve. The rack passes through the inner wall of the first sliding groove via the first fixed post, thereby causing the second rotating wheel to slide on the outer wall of the rotating shaft via the second slot. This causes the second rotating hole to disengage from the outer wall of the rotating post, thus achieving rapid unloading of the LED copper strip on the device. Attached Figure Description
