Technical Field

[0001] This utility model relates to the field of display manufacturing equipment technology, specifically to a laser cutting device for an automatic spacer strip attaching machine. Background Technology

[0002] The current method for attaching spacer strips to the four sides of a monitor frame is mainly manual. First, the person manually places the sheet material for the spacer strip onto a cutting machine frame, and then the cutter on the frame cuts the sheet material into spacer strips. The traditional cutting method results in inaccurate cuts. Moreover, the manual feeding and pushing method is inefficient and poses safety hazards during the cutting process. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a laser cutting device for an automatic spacer strip attaching machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A laser cutting device for an automatic spacer strip attachment machine includes a frame, a hopper and a cutting mechanism on the frame, and the hopper is used to stack spacer strip sheet materials.

[0006] A transverse guide rail is provided between the hopper and the cutting mechanism. A feeding robot is slidably connected to the transverse guide rail. The feeding robot is driven by the transverse drive mechanism to move back and forth on the transverse guide rail. The feeding robot picks up the spaced strip-shaped material in the hopper and transfers it to the cutting mechanism.

[0007] The cutting mechanism includes a cutting table, an XYZ three-axis moving module, and a laser cutting head. The XYZ three-axis moving module is mounted above the cutting table, and the laser cutting head is connected to the XYZ three-axis moving module. The XYZ three-axis moving module drives the laser cutting head to move left and right, forward and backward, and up and down.

[0008] The cutting table has a pushing assembly, which includes a slide table. The slide table is slidably connected to a pushing guide rail at the bottom of the cutting table surface. The slide table is driven by a pushing driver to move along the pushing guide rail. The front end face of the slide table has a clamping driver. The bottom of the clamping driver is connected to an upper clamping plate. Below the upper clamping plate is a lower clamping plate fixedly connected to the slide table. The clamping driver drives the upper clamping plate to press down and cooperate with the lower clamping plate to clamp the spaced strip-shaped material. The front end of the cutting table has a cutting groove. The pushing driver drives the slide table to move forward intermittently a predetermined distance.

[0009] Furthermore, the loading robot includes a lifting module and a robotic arm. The lifting module drives the robotic arm to move up and down, and the free end of the robotic arm is equipped with multiple vacuum nozzles.

[0010] Furthermore, the pusher driver includes two synchronous belt mechanisms that move synchronously and are located on the left and right sides of the cutting table. The drive pulleys of the two synchronous belt mechanisms are connected by a synchronous shaft, which is driven to rotate by a stepper motor.

[0011] Furthermore, the XYZ three-axis moving module includes an X-axis drive module, a Y-axis drive module, and a Z-axis drive module. The X-axis drive module is mounted on top of the frame, and the Y-axis drive module is connected to the X-axis drive module, driving the Y-axis drive module to move along the front-back direction of the frame. The Z-axis drive module is connected to the Y-axis drive module, driving the Z-axis drive module to move along the left-right direction of the frame. The laser cutting head is connected to the Z-axis drive module, which drives the laser cutting head to move up and down.

[0012] The present invention adopts the above technical solution and has the following beneficial effects:

[0013] 1. This utility model uses an XYZ three-axis moving module to drive a laser cutting head to laser cut spacer strips. The laser cutting head focuses the light beam onto the surface of the spacer strips and moves precisely in three directions (X, Y, and Z) to control the laser cutting head to move and cut according to a preset path. By dynamically adjusting the focus, the laser is kept at the optimal cutting position, achieving efficient and precise cutting accuracy.

[0014] 2. The feeding assembly clamps the spaced strip-shaped material and moves it forward a distance each time, working in conjunction with the laser cutting head to achieve efficient and precise cutting;

[0015] 3. Automated feeding is achieved through a robotic arm, which effectively improves production efficiency and safety. Attached Figure Description

[0020] like Figure 1-3 As shown, the present invention provides a laser cutting device for an automatic spacer strip attachment machine, which includes a frame 1, a hopper 2 and a cutting mechanism 3 on the frame 1, and the hopper 2 is used to stack and place spacer strip sheet materials.

[0021] A transverse guide rail 4 is provided between the hopper 2 and the cutting mechanism 3. A loading robot 5 is slidably connected to the transverse guide rail 4. The loading robot 5 is driven by a transverse drive mechanism to move back and forth on the transverse guide rail 4. The function of the loading robot 5 is to pick up the spacer strip-shaped material from the hopper 2 and transfer it to the cutting mechanism 3. The transverse drive mechanism that drives the loading robot 5 can be a lead screw servo system or a cylinder. The loading robot 5 includes a lifting module 51 and a robotic arm 52. The lifting module 51 drives the robotic arm 52 to move up and down. The free end of the robotic arm 52 is provided with multiple vacuum nozzles 53, which pick up the spacer strip-shaped material without damaging it.

[0022] The cutting mechanism 3 includes a cutting table 31, an XYZ three-axis moving module 32, and a laser cutting head 33. The XYZ three-axis moving module 32 is mounted above the cutting table 31, and the laser cutting head 33 is connected to the XYZ three-axis moving module 32, which drives the laser cutting head 33 to move left and right, forward and backward, and up and down. The XYZ three-axis moving module 32 is the same as existing three-axis drive systems, specifically including an X-axis drive module, a Y-axis drive module, and a Z-axis drive module. The X-axis drive module is mounted above the frame 1, and the Y-axis drive module is connected to it, driving the Y-axis drive module to move forward and backward along the frame 1. The Z-axis drive module is connected to the Y-axis drive module, driving the Z-axis drive module to move left and right along the frame 1. The laser cutting head 33 is connected to the Z-axis drive module, which drives the laser cutting head 33 to move up and down.

[0023] The cutting table 31 has a pushing assembly, which includes a slide 34. The slide 34 is slidably connected to a pushing guide rail at the bottom of the table surface of the cutting table 31. The slide 34 is driven by a pushing driver 35 to move along the pushing guide rail. The front end face of the slide 34 has a clamping driver 36. The bottom of the clamping driver 36 is connected to an upper clamping plate 37. Below the upper clamping plate 37, there is a lower clamping plate 38 fixedly connected to the slide 34. The clamping driver 36 drives the upper clamping plate 37 to press down and cooperate with the lower clamping plate 38 to clamp the spaced strip-shaped material. The front end of the cutting table 31 has a cutting groove 311. The pushing driver 35 drives the slide 34 to move forward intermittently a predetermined distance.

[0024] The pusher driver 35 includes two synchronous belt mechanisms that move synchronously and are located on the left and right sides of the cutting table 31. The drive pulleys of the two synchronous belt mechanisms are connected by a synchronous shaft, which is driven to rotate by a stepper motor. The pusher driver 35 can accurately move the spacer strip sheet forward a predetermined distance to ensure the accuracy of the spacer strip size.

[0025] In this utility model, the lifting module 51 of the loading robot 5 and the X-axis drive module, Y-axis drive module and Z-axis drive module of the XYZ three-axis moving module 32 can all adopt the ball screw servo system in the prior art.

[0026] The working process of this utility model is as follows: The loading robot 5 picks up the spacer strip material from the hopper 2 and then transfers it to the cutting table. The slide 34 of the pushing assembly moves forward, and at the same time, the upper clamping plate 37 presses down to cooperate with the lower clamping plate 38 to clamp and fix the spacer strip material. At this time, the loading robot 5 releases the spacer strip material and returns to its original position. The slide 34 moves forward a predetermined distance and then stops. The laser cutting head 33 cuts along the cutting groove 311 to form spacer strips. Finally, the spacer strips formed by the cutting are picked up by other robots and transferred to the next process.

[0027] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
