Description

Technical Field

[0001] This invention relates to the field of machining, and more specifically, to a multi-blade cutting mechanism for an automatic LED strip depaneling machine. Background Technology

[0002] LED lights are being used more and more widely in daily life. To increase the illuminance, LED chips are often fabricated on a single board, known as a LED strip. In mass production of LED strips, to improve efficiency, several strips are often combined into one large strip and connected by a break strip. In practice, LED light manufacturers cut this large strip into individual strips at the break strip for assembly in the next stage.

[0003] Current cutting equipment requires manual placement of the headlight strip to be cut on the cutting table before cutting can begin. This results in low operational efficiency. After the light strip is cut, it still needs to be manually removed, making the entire process discontinuous and lacking in automation. Furthermore, manual placement can easily lead to misalignment of the light strip, further complicating the control of cutting precision. Summary of the Invention

[0004] In view of the problems of low efficiency of manual feeding and low degree of automation of unloading in the existing technology, the purpose of this invention is to provide a multi-blade cutting mechanism for an automatic LED strip PCB separator.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] An automatic LED strip depaneling machine with a multi-blade cutting mechanism includes a frame on which a drive motor, a multi-sided rotating table, a linear cutting mechanism, and a feeding mechanism are mounted. The drive motor drives the multi-sided rotating table to rotate at a fixed angle inside the frame. The feeding mechanism is located directly below the multi-sided rotating table and is used to feed the multi-sided rotating table. The linear cutting mechanism is located directly above the multi-sided rotating table and is used to cut the LED strips on the table.

[0007] As a further description of the above technical solution: the multi-faceted flipping table is an integral square structure, and four work surfaces are provided on the outside of the multi-faceted flipping table. A light strip carrier plate is movably installed on the work surface, and an electric push rod for driving the vertical movement of the light strip carrier plate is installed inside the multi-faceted flipping table.

[0008] As a further description of the above technical solution: the outer side of the light strip carrier plate is provided with continuous cutting grooves, and a breathable foam pad is provided between two adjacent cutting grooves. An electric suction cup matrix that communicates with the inside of the breathable foam pad is installed inside the workbench.

[0009] As a further description of the above technical solution: the outer side of the light strip carrier plate is provided with a side guide block that is perpendicular to and engages with the feeding mechanism.

[0010] As a further description of the above technical solution: the feeding mechanism includes a material rack, a bottom cylinder and a push plate. The bottom cylinder is installed inside the material rack, and the movable end of the bottom cylinder is fixedly connected to the push plate. The outer side of the push plate is vertically slidably connected to the inside of the material rack. All four sides of the material rack are provided with matching grooves that are vertically engaged with the side guide blocks.

[0011] As a further description of the above technical solution: the linear cutting mechanism includes a linear electric drive rail, a vertical cylinder, and a driven cutting roller. The linear electric drive rail is fixedly installed on the frame. The linear electric drive rail is used to start the vertical cylinder to move linearly back and forth. The vertical cylinder is used to drive the cutting roller to raise and lower its height. The blades on the cutting roller are correspondingly engaged with the cutting grooves.

[0012] As a further description of the above technical solution: a side cylinder is fixedly installed on the side of the frame, and a side pressure plate is fixedly connected to the movable end of the side cylinder. The side pressure plate corresponds to and cooperates with the workbench on the side. A perforated rubber plate is fixedly connected to the side of the side pressure plate facing the workbench. The side pressure plate is provided with holes of the same specification that communicate with the holes on the perforated rubber plate.

[0013] As a further description of the above technical solution: the bottom of the frame is provided with a receiving groove, which is located on the side opposite to the side pressure plate.

[0014] Compared with the prior art, the advantages of this invention are:

[0015] I. This Solution: This solution utilizes a multi-faceted rotating table with fixed-angle rotation, combined with the cyclical switching of light strip carrier plates at four workstations. After automatic loading at the loading station, the table rotates to the cutting station for simultaneous multi-blade cutting. After cutting, it rotates to the unloading station for automatic unloading. This allows the loading, cutting, and unloading processes to be carried out simultaneously, eliminating the waiting intervals for manual loading and unloading. The overall operating efficiency is significantly improved compared to traditional equipment, greatly enhancing the automation level and processing efficiency of the overall cutting operation.

[0016] II. This solution uses an electric suction cup matrix in conjunction with a breathable foam pad to vacuum-adhere and fix the LED strip. It can not only use uniform vacuum suction to completely and flatly adsorb the LED strip, avoiding local warping and displacement, but also rely on the flexible cushioning properties of the breathable foam pad to avoid scratching the LED beads and deforming the board surface caused by direct contact between the hard suction cup and the LED strip. It is suitable for fixing flexible LED strips and rigid PCB LED strips of different thicknesses and specifications.

[0017] Third, this solution combines the one-to-one correspondence between multiple blades on the cutting roller and the cutting groove, which can complete the synchronous cutting of all fracture zones at one time without repeated cutting. This ensures cutting accuracy while further improving the efficiency of cutting operations and solves the problems of discontinuous operation and low degree of automation of traditional equipment.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] To address the issue of low operational efficiency caused by the need for manual placement of the headlight strip to be cut on the cutting table before cutting can begin with cutting equipment, Implementation Example 1 is proposed:

[0028] Please see Figures 1-6In this invention, an automatic LED strip depaneling machine with a multi-blade cutting mechanism includes a frame 1 on which a drive motor 2, a multi-sided rotating table 3, a linear cutting mechanism 4, and a feeding mechanism 5 are mounted. The drive motor 2 is used to drive the multi-sided rotating table 3 to rotate at a fixed angle inside the frame 1. The feeding mechanism 5 is located directly below the multi-sided rotating table 3 and is used to feed materials onto the multi-sided rotating table 3. The linear cutting mechanism 4 is located directly above the multi-sided rotating table 3 and is used to cut the LED strips on the table.

[0029] The multi-faceted rotating table 3 is an integral square structure. Four work surfaces 31 are provided on the outside of the multi-faceted rotating table 3. A light strip carrier plate 32 is movably installed on the work surface 31. An electric push rod 33 for driving the light strip carrier plate 32 to move vertically is installed inside the multi-faceted rotating table 3.

[0030] The outer side of the light strip carrier plate 32 is provided with a continuous cutting groove 321, and a breathable foam pad 322 is provided between two adjacent cutting grooves 321. An electric suction cup matrix 323 communicating with the inside of the breathable foam pad 322 is installed inside the worktable surface 31.

[0031] The outer side of the light strip carrier plate 32 is provided with a side guide block 324 that is perpendicular to and engages with the feeding mechanism 5.

[0032] The feeding mechanism 5 includes a material rack 51, a bottom cylinder 52 and a push plate 53. The bottom cylinder 52 is installed inside the material rack 51. The movable end of the bottom cylinder 52 is fixedly connected to the push plate 53. The outer side of the push plate 53 is vertically slidably connected to the inside of the material rack 51. All four sides of the material rack 51 are provided with matching grooves 511 that are vertically engaged with the side guide block 324.

[0033] The linear cutting mechanism 4 includes a linear electric drive rail 41, a vertical cylinder 42, and a driven cutting roller 43. The linear electric drive rail 41 is fixedly installed on the frame 1. The linear electric drive rail 41 is used to start the vertical cylinder 42 to move linearly back and forth. The vertical cylinder 42 is used to drive the cutting roller 43 to raise and lower its height. The blades on the cutting roller 43 are correspondingly engaged with the cutting groove 321.

[0034] In this invention, the light strips to be cut are first vertically stacked and placed on the push plate 53 inside the material rack 51. A multi-faceted rotating table 3 is used to set up four cyclically rotating worktables 31, which, together with the bottom feeding mechanism 5, complete the automatic feeding. Specifically, during feeding, the multi-faceted rotating table 3 rotates the empty worktables 31 to the lower position. The light strip carrier plate 32 extends downward under the drive of the electric push rod 33. The side guide block 324 is inserted into the fitting groove 511 of the material rack 51. The bottom cylinder 52 pushes the push plate 53 to push the stacked light strip pieces as a whole onto the surface of the breathable foam pad 322 of the light strip carrier plate 32. The electric suction cup matrix 323 is activated, and the light strip pieces are flattened and fixed through the breathable foam pad 322. Subsequently, the electric push rod 33 drives the light strip carrier plate 32 back to its original position. The multi-faceted rotating table 3 retracts and rotates at a fixed angle, rotating the worktable 31 with the LED strip attached to it to the upper cutting position, completing the automatic feeding process. During the cutting process, the vertical cylinder 42 pushes the cutting roller 43 downward, and the multiple sets of blades on the cutting roller 43 rotate and cut into the cutting groove 321 of the LED strip carrier plate 32. The linear electric drive rail 41 drives the cutting roller 43 to move linearly, completing the synchronous cutting of multiple LED strips at one time. After the cutting is completed, the multi-faceted rotating table 3 continues to rotate, rotating the cut worktable 31 to the next station for unloading. At the same time, another empty worktable 31 rotates to the bottom to repeat the feeding steps, realizing continuous automated operation of the cutting operation. There is no need for manual laying of LED strips one by one, which effectively improves the operating efficiency and cutting flatness.

[0035] Building upon the solutions for automated feeding and synchronous cutting, and addressing the pain points of existing unloading processes relying on manual labor and lacking operational continuity, this invention further optimizes the side clamping and automatic unloading structure, proposing Embodiment Two:

[0036] Please see Figure 2 The side of the frame 1 is fixedly installed with a side cylinder 6. The movable end of the side cylinder 6 is fixedly connected with a side pressure plate 7. The side pressure plate 7 is correspondingly matched with the worktable 31 on the side. A perforated rubber plate 71 is fixedly connected to the side of the side pressure plate 7 facing the worktable 31. The side pressure plate 7 is provided with holes of the same specification that communicate with the holes on the perforated rubber plate 71.

[0037] The bottom of the frame 1 is provided with a receiving groove 8, which is located on the opposite side of the side pressure plate 7.

[0038] In this invention, after the material is loaded, the multi-faceted flipping table 3 rotates the cut worktable 31 to the position where the side pressure plate 7 is located. Then, the control end starts the side cylinder 6 to drive the side pressure plate 7 to move and press the side of the LED strip being adsorbed, so that it is more flat and tighter with the LED strip carrier plate 32, avoiding loosening of the side and ensuring cutting stability. At the same time, the porous rubber plate 71 achieves flexible compression on the surface of the LED strip, protecting the LED strip and avoiding scratches. The holes are used to prevent negative pressure adsorption when the porous rubber plate 71 separates from the LED strip, ensuring the pressing effect. Then, the worktable 31 continues to be driven to rotate to the top cutting position, and the LED strip on the cut worktable 31 rotates synchronously to the top of the receiving groove 8. At this time, the control of the electric suction cup matrix 323 stops adsorption, and the cut LED strip falls into the receiving groove 8 under its own gravity. Thus, the device realizes automated operation of loading, cutting and unloading, with a high degree of automation and higher efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
