To achieve this purpose, this invention provides the following technical solution: An automatic LED strip cutting machine includes a gantry frame. A slider and a slider drive device are mounted on the crossbeam of the gantry frame. A feeding device and a cutting device are located at one end of the gantry frame. A first clamp is mounted on the slider, and the first clamp is connected to a first cylinder. The first cylinder can drive the first clamp to clamp or release the LED strip. The slider drive device can drive the slider to reciprocate on the crossbeam. The feeding device includes a feed inlet facing one end of the crossbeam. The cutting device includes an upper knife post and a lower knife post located inside the feed inlet in a vertical direction. A knife is mounted on one of the upper or lower knife posts, and a corresponding cutting slit is provided on the other knife post. The upper and lower knife posts are mounted on a fourth cylinder, which can drive the knife and cutting slit on the upper and lower knife posts to engage and cut the LED strip.

The slider 3 is located close to the first feeding device. The upper and lower pulley groups of the two feeding devices are in a separated position. The upper and lower knife holders of the two cutting devices are in a retracted position away from the light strip travel path. 2) Insert the two light strips into the feed inlets 50 of the two feeding devices respectively, and pass between the upper and lower pulley sets. The feed inlets 50 and their clamping wheels 51 can level and adjust the light strip L so that it can maintain a straight state after passing through the feed inlets. 3) Start the machine. The first cylinder Q1 starts, driving the first clamp 341 to clamp the end of the light strip L. The third cylinder Q3 of the two feeding devices starts, driving the upper and lower pulley sets to clamp the light strip L. 4) The traction motor M1 and the feeding motor M2 of the first feeding device start synchronously, the slider 3 pulls the light strip L forward, and at the same time, the fifth cylinder Q5 of the first cutting device starts, driving the upper and lower knife holders to the position of the light strip. 5) After the slider 3 pulls the light strip L through a predetermined distance, it stops. The fourth cylinder Q4 of the first cutting device starts, drives the upper and lower blade holders to engage and cut the light strip, and then resets. Then the fifth cylinder Q5 of the first cutting device starts, drives the upper and lower blade holders to retract to the initial position. 6) The slider 3 continues to move forward to the second feeding device, the second cylinder Q2 of the slider is activated, and the second clamp 342 is driven to clamp the end of the light strip L on the second feeding device; 7) When the traction motor M1 reverses, the feeding motor M2 of the second cutting device starts synchronously, the slider 3 pulls the light strip L back, and at the same time, the fifth cylinder Q5 of the second cutting device starts, driving the upper and lower knife holders to the position of the light strip. 8) After the slider 3 pulls the light strip L through a predetermined distance, it stops. The fourth cylinder Q4 of the second cutting device starts, driving the upper and lower cutter holders to engage and cut the light strip L before resetting.

[0029] 9) The first clamp 341 of the slider 3 re-clamps the light strip on the first feeding device, and so on.

[0030] When the gantry frame has only one end equipped with a feeding device and a cutting device, after step 5) is completed, slider 3 returns to its initial position and clamps the light strip again, repeating this process. Preferably, this invention has two sets of feeding devices and cutting devices at each end of the gantry frame, which not only improves production efficiency but also allows for the simultaneous cutting of two light strips of different lengths. This invention, due to its automated light strip cutting, offers advantages such as low labor costs and high work efficiency.
