Description

Technical Field

[0001] This invention relates to the field of non-standard laser cutting equipment technology, specifically a laser cutting mechanism for processing non-standard metal parts. Background Technology

[0002] In high-precision fields such as mobile phone frames, semiconductor silicon wafers, and medical devices, ultrashort pulse laser technology (such as picosecond and femtosecond lasers) is used to cut metal plates to achieve smooth, ablation-free, and burr-free cuts. Existing ultrashort pulse laser cutting equipment typically uses a mesh grid or other support structure below the cut to support the metal plate. However, the laser cutter briefly contacts this support structure after penetrating the metal plate, causing some damage and requiring frequent replacement, resulting in waste.

[0003] Therefore, we propose a laser cutting mechanism for processing non-standard metal parts to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a laser cutting mechanism for processing non-standard metal parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting mechanism for processing non-standard metal parts, comprising: a gantry-type three-axis structure, a conveyor line, and a cutting workpiece stage, wherein the gantry-type three-axis structure is located above the conveyor line, the Z-axis module of the gantry-type three-axis structure is driven and connected to a laser cutting head, the laser cutting head is connected to a laser, and the cutting workpiece stage is conveyed on the conveyor line; The cutting platform includes a support frame, with several support rods slidably arranged in the middle of the support frame. The support rods are movably sleeved on the through rod, and a set of linear drive structures for the support rods are connected to both ends of the through rod. Each set of linear drive structures for the support rods includes two guide plates, upper and lower, which are fixedly connected to the support frame. Each of the two guide plates has a guide rail corresponding to the number of support rods on its opposite side. A lead screw corresponding to the number of support rods is rotatably installed inside the guide plates. The lead screws are arranged in a side-by-side array, and each lead screw is connected to a servo reduction motor at its end. The servo reduction motor drives the lead screw to rotate. Each of the through rods has a slider fixedly installed at both ends. Guide grooves are opened on the upper and lower surfaces of the sliders. The guide grooves are slidably connected to the guide rails. The sliders are threadedly connected to the lead screw. The through rods are designed with a specified length according to the position of the sliders at their ends. Part of the through rods slides through the lead screws that are not connected to them.

[0006] Preferably, the conveyor line is an adjustable spacing conveyor structure with the middle section in an empty state, and a recycling box can be installed below the conveyor line.

[0007] Preferably, the conveyor line includes a fixed support rail and a movable support rail. The movable support rail is mounted on a linear module, and the linear module drives the movable support rail to move closer to or away from the fixed support rail.

[0008] Preferably, both the fixed support track and the movable support track are provided with guide rails on their upper surfaces, and a traveling trolley is slidably mounted on the guide rails, with a cutting platform placed on the traveling trolley.

[0009] Preferably, both the fixed support track and the movable support track are provided with a circulating conveyor belt on their sides. The conveyor belt is fixedly connected to the traveling trolley. A servo motor is fixedly installed on the fixed support track, and the servo motor drives the conveyor belt.

[0010] Preferably, a telescopic transmission rod is connected between the conveyor belts on the fixed support track and the movable support track. The telescopic transmission rod is composed of two hexagonal prisms with transmission sleeves slidably fitted on their outer sides.

The first support rod and the second support rod are located between the first support compensation rod and the second support compensation rod, and the first support rod and the second support rod play the main supporting role. The light emitted by the laser cutting head is located between the first support rod and the second support rod. The light emitted by the laser cutting head travels, and the first support rod and the second support rod follow. The first support rod or the second support rod moves away from under the non-standard metal part, and the first support compensation rod or the second support compensation rod travels to under the non-standard metal part to compensate and support it.

[0013] Compared with the prior art, the beneficial effects of the present invention are: By replacing the existing mesh support grid with a cutting platform, the cutting platform uses multiple independently moving support rods to support the cutting area.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-9 The present invention provides a technical solution: a laser cutting mechanism for processing non-standard metal parts, comprising: a gantry-type three-axis structure 1, a conveyor line 2 and a cutting platform 3, wherein the gantry-type three-axis structure 1 is located above the conveyor line 2, the Z-axis module of the gantry-type three-axis structure 1 is driven and connected to a laser cutting head 4, the laser cutting head 4 is connected to a laser, and the cutting platform 3 is conveyed on the conveyor line 2. A metal plate is placed on the cutting platform 3. The cutting platform 3 is transported by the conveyor line 2 to the bottom of the gantry-type three-axis structure 1. The laser cutting head 4 is driven by the gantry-type three-axis structure 1 to move along the X, Y and Z axes to perform non-standard cutting on the metal plate on the cutting platform 3.

[0018] Conveyor line 2 is an adjustable spacing conveyor structure with the middle section in an empty state. A recycling box can be set below conveyor line 2. The cut non-standard metal parts will fall into the recycling box. Non-transparent cooling water or other coolant is set in the recycling box to collect the non-standard metal parts.

[0019] The conveyor line 2 includes a fixed support rail 21 and a movable support rail 22. The movable support rail 22 is set on the linear module 23. The linear module 23 drives the movable support rail 22 to move closer to or further away from the fixed support rail 21 to adjust the spacing to meet the different sizes of steel plates.

[0020] Guide rails 24 are provided on the upper surfaces of both the fixed support rail 21 and the movable support rail 22. A traveling trolley 25 is slidably mounted on the guide rail 24. The cutting platform 3 is placed on the traveling trolley 25. The traveling trolley 25 moves along the guide rail 24 to send the cutting platform 3 into or out of the gantry-type three-axis structure 1.

[0021] Both the fixed support rail 21 and the movable support rail 22 are equipped with circulating conveyor belts 26 on their sides. The conveyor belts 26 are fixedly connected to the traveling trolley 25. A servo motor 28 is fixedly installed on the fixed support rail 21. The servo motor 28 drives the conveyor belt 26. The servo motor 28 drives the conveyor belt 26 to move, thereby moving the traveling trolley 25.

[0022] A telescopic transmission rod 27 is connected between the conveyor belts 26 on the fixed support track 21 and the movable support track 22. The telescopic transmission rod 27 is composed of two hexagonal prisms with transmission sleeves sliding on their outer sides. The two hexagonal prisms are respectively connected to the two conveyor belts 26. The hexagonal prisms are axially sliding and radially fixedly connected to the transmission sleeves. When the distance between the fixed support track 21 and the movable support track 22 is adjusted, the synchronous transmission of the conveyor belts 26 between the two is ensured.

[0023] The cutting platform 3 includes a support frame 31. The support frame 31 has straight grooves 311 at both ends. Several support rods are slidably arranged in the middle of the support frame 31. The support rods are sleeved on the through rod 37. The two ends of the through rod 37 slide through the straight grooves 311. Both ends of the through rod 37 are connected to a set of support rod linear drive structures 36. To illustrate more clearly, this embodiment uses four support rods, functionally divided into a first support compensation rod 32, a first support rod 33, a second support rod 34, and a second support compensation rod 35. The first support rod 33 and the second support rod 34 are located between the first support compensation rod 32 and the second support compensation rod 35. The first support rod 33 and the second support rod 34 play the main supporting role, providing stable support for the non-standard processed parts. The light emitted by the laser cutting head 4 is located between the first support rod 33 and the second support rod 34. When the light emitted by the laser cutting head 4 travels, the first support rod 33 and the second support rod 34 follow, ensuring that the light does not directly contact the support rods after passing through the metal plate, thus preventing damage to the support rods. When cutting to the edge of the non-standard metal part, the first support rod 33 or the second support rod 34 moves away from under the non-standard metal part, and at the same time, it travels under the non-standard metal part through the first support compensation rod 32 or the second support compensation rod 35, providing compensation support for the non-standard metal part. During the entire cutting process, at least two support rods are kept under the non-standard metal part.

[0024] Each set of support rod linear drive structure 36 includes two guide plates 361, upper and lower. The guide plates 361 are fixedly connected to the support frame 31. Each of the two guide plates 361 has a guide rail 3611 corresponding to the number of support rods on its opposite side. The guide plates 361 are rotatably equipped with a lead screw 363 corresponding to the number of support rods. The lead screws 363 are arranged in a side-by-side array. Each end of the lead screw 363 is connected to a servo reduction motor 362, which drives the lead screw 363 to rotate. Each through rod 37 has a slider 364 fixedly installed at both ends. The slider 364 has guide grooves 3641 on its upper and lower sides. The guide grooves 3641 are slidably connected to the guide rail 3611. The slider 364 is threadedly connected to the lead screw 363. The through rod 37 is designed to be of different lengths according to the position of the slider 364. Some of the through rods 37 slide through the lead screw 363 that is not connected to them, so that each lead screw 363 drives different through rods 37 to move, thereby realizing the independent movement of each support rod.

[0025] Working principle: The metal sheet is placed on the support frame 31, and then the cutting platform 3 is placed on the traveling trolley 25. The servo reduction motor 362 on the cutting platform 3 is connected to the control circuit. The traveling trolley 25 is moved to the bottom of the gantry three-axis structure 1 through the conveyor belt 26. The laser cutting head 4 is driven by the gantry three-axis structure 1 to perform non-standard cutting on the metal sheet on the support frame 31. During the cutting process, the servo reduction motor 362 is activated as needed to drive the lead screw 363 to rotate, which in turn drives the slider 364 to move linearly along the guide rail 3611. This causes the support rod or support compensation rod to enter below the cutting area to support the cutting area. At the same time, the support rod or support compensation rod is positioned on both sides of the laser to prevent the laser from damaging the support rod. After the cutting is completed, the support rod or support compensation rod detaches from the non-standard metal part, and the metal part falls freely into the recycling box below.
