Multi-blade cutting mechanism of LED lamp strip automatic board dividing machine

Abstract

This utility model discloses a multi-blade cutting mechanism for an automatic LED strip PCB separator, including a frame. The frame has two drive rails, a moving frame, a lifting mechanism, a cutting device, and a clamping component. The frame has multiple parallel blade slots. The two drive rails drive the moving frame to reciprocate linearly on the frame. The lifting mechanism, mounted on the moving frame, drives the cutting device to move vertically on the moving frame. This utility model utilizes the blade slots on the frame in conjunction with the clamping component to guide the cutting device, enabling simultaneous multi-blade cutting of flexible LED strips. A negative pressure pump creates negative pressure inside the inner slots, and the LED strips are attracted through vertical channels, stabilizing the strips on the frame. This achieves stability and high efficiency during simultaneous multi-strip cutting, resulting in a highly efficient positioning effect and significantly improved cutting stability and efficiency.

Description

Technical Field

[0001] This utility model relates to the field of LED light strip cutting technology, and more specifically, to a multi-blade cutting mechanism for an automatic LED light strip slitting machine. Background Technology

[0002] LED strip automatic PCB splitting machine is an automated device used to divide large LED circuit boards (such as aluminum substrates and FR4 boards) into independent small units. It is mainly used in the electronic manufacturing fields such as LED strips and PCB circuit boards.

[0003] Currently, automatic PCB depaneling machines for rigid substrate LED light strips generally use circular blade cutting technology, which involves multiple progressive cuts. However, LED light strips with flexible substrates cannot be effectively cut using the above-mentioned cutting mechanism. Furthermore, traditional cutting mechanisms typically employ single-blade reciprocating cutting or manual-assisted positioning cutting, which not only results in low cutting efficiency but also makes it difficult to meet the needs of mass production. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a multi-blade cutting mechanism for an automatic LED strip depaneling machine, so as to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] The multi-blade cutting mechanism of the automatic LED strip depaneling machine includes a frame, on which two drive rails, a moving frame, a lifting mechanism, a cutting device, and a clamping component are provided;

[0007] The frame is provided with multiple parallel tool slots;

[0008] The two drive rails are used to drive the moving frame to move linearly back and forth on the frame, and the lifting mechanism is installed on the moving frame to drive the cutting device to move vertically on the moving frame;

[0009] The cutting device includes a drive motor, a rotating shaft, and blades arranged at equal intervals. The drive motor is mounted on a lifting mechanism, and the output end of the drive motor is fixedly connected to the rotating shaft via a coupling. The blades are fixedly mounted on the rotating shaft at equal intervals, and the rotating shaft is rotatably mounted on the lifting mechanism.

[0010] The clamping component includes a servo motor, a long shaft, and grippers. The servo motor is fixedly mounted on the frame, and the output end of the servo motor is fixedly connected to one end of the long shaft via a coupling. The other end of the long shaft is rotatably mounted on the frame.

[0011] As a further description of the above technical solution: the lifting mechanism includes a drive cylinder and a lifting frame. The drive cylinder is fixedly installed on the movable frame. The movable end of the drive cylinder extends slidably to the bottom of the movable frame and is fixedly connected to the lifting frame. The outer side of the lifting frame is slidably installed to the inner side of the movable frame.

[0012] As a further description of the above technical solution: the top of the lifting frame is provided with a vertical guide rod, which slides into the interior of the moving frame.

[0013] As a further description of the above technical solution: the claw groove of the gripper corresponds to and engages with the blade head.

[0014] As a further description of the above technical solution: the frame has an inner groove, and the inner groove has multiple sets of vertical channels extending upward to the top of the frame. A negative pressure pump communicating with the inner groove is installed on the right side of the frame.

[0015] As a further description of the above technical solution: the vertical channel group is arranged longitudinally and located between two adjacent knife slots, and the hole positions of the vertical channel group correspond to the lamp beads of the LED light strip.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This solution utilizes the blade groove on the frame in conjunction with the clamping component to guide the cutting device, enabling multiple blades to simultaneously cut flexible LED light strips, thus achieving the advantage of the device being able to efficiently cut flexible LED light strips.

[0018] This solution uses a negative pressure pump to draw negative pressure into the inner tank and uses vertical channel groups to adsorb the LED light strips, stabilizing the main body of the light strips on the frame. This achieves stability and efficiency when cutting multiple strips simultaneously, thus enabling the device to have a highly efficient positioning effect and effectively improve cutting stability and efficiency.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] To address the problem that existing automatic LED strip splitting machines cannot effectively cut LED strips on flexible substrates, Example 1 is proposed:

[0027] Please see Figure 1-4 In this embodiment, the multi-blade cutting mechanism of the automatic LED strip depaneling machine includes a frame 1, on which two drive rails 2, a moving frame 3, a lifting mechanism 4, a cutting device 5, and a clamping component 6 are provided; multiple parallel blade slots 7 are opened on the frame 1; the two drive rails 2 are used to drive the moving frame 3 to move linearly back and forth on the frame 1, and the lifting mechanism 4 is installed on the moving frame 3 to drive the cutting device 5 to move vertically on the moving frame 3.

[0028] The cutting device 5 includes a drive motor 51, a rotating shaft 52, and blade heads 53 arranged at equal intervals. The drive motor 51 is mounted on the lifting mechanism 4. The output end of the drive motor 51 is fixedly connected to the rotating shaft 52 through a coupling. The blade heads 53 are fixedly mounted on the rotating shaft 52 at equal intervals. The rotating shaft 52 is rotatably mounted on the lifting mechanism 4.

[0029] The clamping component 6 includes a servo motor 61, a long shaft 62, and a gripper 63. The servo motor 61 is fixedly mounted on the frame 1. The output end of the servo motor 61 is fixedly connected to one end of the long shaft 62 through a coupling. The other end of the long shaft 62 is rotatably mounted on the frame 1. The gripper groove of the gripper 63 is correspondingly engaged with the blade head 53.

[0030] The lifting mechanism 4 includes a drive cylinder 41 and a lifting frame 42. The drive cylinder 41 is fixedly installed on the movable frame 3. The movable end of the drive cylinder 41 extends slidably to the bottom of the movable frame 3 and is fixedly connected to the lifting frame 42. The outer side of the lifting frame 42 is slidably installed to the inner side of the movable frame 3. A vertical guide rod 421 is provided at the top of the lifting frame 42. The vertical guide rod 421 extends slidably into the interior of the movable frame 3.

[0031] In this embodiment, the LED light strip to be cut is laid flat on the frame 1, and the cutting lines between the LED light strips are aligned with the blade grooves 7, so that the ends are close to the grippers 63. Then, the servo motor 61 is started to drive the long shaft 62 to rotate at a fixed angle, so that the grippers 63 press the ends of the LED light strips. Then, the drive cylinder 41 is started to drive the lifting frame 42 to descend, and at the same time, the drive motor 51 is started to drive the rotating shaft 52 and the blade head 53 to rotate. As the lifting frame 42 descends, the blade head 53 passes through the claw grooves of the grippers 63 and gradually contacts and cuts the LED light strips. At the same time, the two drive rails 2 are started to drive the moving frame 3 to move in a straight line at a uniform speed, so as to realize the one-time cutting of multiple LED light strips, thereby realizing the advantage of the device in efficiently cutting flexible LED light strips.

[0032] Furthermore, addressing the issue that traditional cutting mechanisms typically employ single-blade reciprocating cutting or manual-assisted positioning cutting, which not only results in low cutting efficiency but also fails to meet the demands of mass production, a second embodiment is proposed:

[0033] Please see Figure 1 and Figure 3 The frame 1 has an inner groove 10 inside, and the inner groove 10 has multiple sets of vertical channels 8 extending upward to the top of the frame 1. A negative pressure pump 9 connected to the inner groove 10 is installed on the right side of the frame 1.

[0034] The vertical channel group 8 is arranged longitudinally and located between two adjacent knife grooves 7. The hole positions of the vertical channel group 8 correspond to the LED beads of the LED light strip.

[0035] In this embodiment, when the LED light strip is laid flat, the LED beads and the top port of the vertical channel group 8 correspond and fit perfectly. At this time, the negative pressure pump 9 is started to draw negative pressure into the inner groove 10, and the LED light strip is adsorbed through the vertical channel group 8, so that the main body of the light strip is stable on the frame 1, so as to achieve stability and efficiency when cutting multiple strips simultaneously. This realizes that the device has a high-efficiency positioning effect and effectively improves the cutting stability and efficiency.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
