Description

Technical Field

[0001] The invention relates to the technical field of laser cutting processing, and in particular to a side material laser cutting machine and an operating method thereof. Background Art

[0002] In recent years, a new exterior decoration process has emerged for products such as mobile phones and speakers - shell fabric, which is to cover the surface of the product shell with decorative fabric. The shell fabric brings users a cloth feel different from the smooth and hard surface, and can also bring a visual sense of luxury. The cloth surface will not be stained with fingerprints or scratched. In the preparation process, an adhesive covering method is generally adopted to ensure the integrity of the cloth surface. The most commonly used bonding method is: first cut the cloth to a preset size, then apply a glue layer on the surface of the shell, and directly align the cloth with the shell. However, this bonding method has the defects of high difficulty in alignment and easy to be skewed. Therefore, in order to overcome this problem, a more advanced method is to use a cloth larger than the preset size to first cover, fit or fix the shell, and then perform laser cutting.

[0003] For example, in the prior art, the Chinese invention patent application with publication number CN112676713A discloses a device and operation method for hot pressing mesh cloth on the surface of a product and laser cutting auxiliary mesh cloth, the device includes a cabinet, a control system, an upper pressing mechanism, an anti-deflection synchronous rotation through processing mechanism and a laser cutting device, the anti-deflection synchronous rotation through processing mechanism has a lower fixture head assembly, a synchronous rotation mechanism with an avoidance part, and two sets of anti-deflection mechanisms that alternately operate and prevent the lower fixture head assembly from deflecting, the avoidance part is arranged on the outside of the lower fixture head assembly, it is driven by the power part on the synchronous rotation mechanism to rotate in a circle, and the avoidance part has a structure to avoid the laser passing through; the laser cutting device has a laser emitting part and an XY axis driving mechanism that drives the laser emitting part to move in the XY axis, and the avoidance part rotates continuously to avoid the laser emitting path of the laser emitting part. This prior art realizes fully automated production by integrating the product package mesh cloth and the redundant auxiliary mesh cloth cutting process into an integrated machine.

[0004] However, there are the following deficiencies in the above prior art:

[0005] 1. After hot pressing, it cannot be guaranteed that there is no wrinkle or functional holes, etc., and it is directly entered into laser cutting after confirmation. The preparation process is not rigorous enough and the yield rate cannot be guaranteed.

[0006] 2. The design of the anti-deflection synchronous rotating through-processing mechanism is relatively complicated. The power unit and the anti-deflection mechanism act together on the lower fixture head assembly. It is easy to cause conflict and damage between the anti-deflection mechanism and the power unit due to operational errors or program errors.

[0007] 3. The laser cutting device is arranged below the synchronous rotating mechanism, and the avoidance part needs to rotate continuously to avoid the laser. The structure is complicated and prone to errors.

[0008] 4. The equipment structure is complex and the manufacturing cost is high.

[0009] 5. There is no solution for unloading the cut waste, which generally requires manual operation, low efficiency and low safety. Summary of the invention

[0037] like Figure 1-10As shown, a laser cutting machine for edge material provided by an embodiment of the present invention comprises: a laser cutting head 1 for emitting laser light to a cutting position 6 located at a processing station; a positioning fixture 2 for loading a first workpiece 3 in the processing station; a pressing device 4 for entering the processing station and pressing a second workpiece 5 covering the surface of the first workpiece 3 onto the positioning fixture 2, wherein the second workpiece 5 and the first workpiece 3 form a component to be processed 39, wherein the second workpiece 5 has a cutting position 6 and an edge material 7 located below the cutting position 6, and the pressing device 4 exits the processing station after the laser cutting is completed; a rotating worktable 8 for driving the positioning fixture 2 to synchronously drive the component to be processed 39 to rotate on a horizontal plane to cooperate with the laser cutting head 1 to perform a laser cutting action on the cutting position 6; a clamping device 9 for entering the processing station and clamping the edge material 7, and sending it out of the processing station after the laser cutting action is completed; a control device for controlling the laser cutting head 1, the rotating worktable 8, the clamping device 9, and the first drive device 21 to execute control instructions. In this embodiment, an automated laser cutting device is formed by a laser cutting head 1, a positioning fixture 2, a material pressing device 4, a rotating table 8, a material clamping device 9 and a control device. The components to be processed composed of the first workpiece 3 and the second workpiece 5 are fixed and placed on the positioning fixture 2 together to ensure that the components to be processed that are cut are accurately aligned and meet the coverage requirements. There is no need to prevent deflection. The positioning fixture 2 is directly controlled by the rotating table 8. When the laser is emitted, the components to be processed are driven to rotate in coordination with the rotating table 8. There is no need to set an avoidance part. The edge material 7 is automatically unloaded through the clamping device. The overall structure is simple and reliable. Specifically, in this embodiment, the first workpiece 3 is a hemispherical shell, and the second workpiece 5 is cloth.

[0038] The laser cutting machine head 1 of the present embodiment is controlled by a lifting device 10 to adjust the height of the laser setting, which is generally pre-adjusted during preparation and does not need to be adjusted again during processing.

[0039] like Figure 3 As shown, the positioning jig 2 of this embodiment has an assembly portion 11 with a raised center and a jig platform 12 arranged around the assembly portion 11. The assembly portion 11 is used to assemble the first workpiece 3. When the second workpiece 5 is covered on the first workpiece 3, the edge material 7 below the cutting position 6 is laid flat on the jig platform 12.

[0040] In addition, the positioning fixture 2 of this embodiment has a first hole 13 for partially suspending the edge material 7, and the first hole 13 is used for the clamping device 9 to enter and clamp the edge material 7, and the first hole 13 serves as a clamping station. The beneficial effects of this embodiment are: the first hole 13 as a clamping station is configured on the positioning fixture 2 to ensure that the clamping device 9 can accurately clamp the edge material 7, thereby realizing automatic unloading, with a simple structure and convenient operation.

[0041] like Figure 7 As shown, the pressing device 4 of this embodiment is a sleeve structure, and the outer peripheral side has an annular groove 14, and the annular groove 14 is provided with a positioning hole 15. The pressing device 4 is sleeved on the periphery of the component to be processed during processing, and the edge material 7 is pressed flat on the positioning fixture 2. In this embodiment, the pressing device 4 with a sleeve structure can press the second workpiece 5 flat on the positioning fixture 2 at 360 degrees along the outer periphery of the first workpiece 3, ensuring that the second workpiece 5 remains relatively still on the positioning fixture 2 with the first workpiece 3, ensuring the stability of the cutting position 6, and having a simple structure and convenient operation.

[0042] In addition, the bottom edge of the outer peripheral side of the pressing device 4 of this embodiment has an annular convex edge 16, which can increase the flat pressing area of ​​the pressing device 4 on the edge material 7, thereby improving the fixing effect on the edge material 7. Then, in order to improve the clamping ability of the clamping device 9 and allow the clamping device 9 to clamp as much edge material 7 as possible, the position of the convex edge 16 corresponding to the first hole position 13 is configured with a second hole position 17, so that the clamping device 9 can enter the first hole position 13 and the second hole position 17 to achieve more possible clamping of the edge material 7, thereby improving the clamping ability of the clamping device 9 and avoiding the failure of automatic material feeding due to insufficient clamping of the edge material 7 due to the edge material 7 being too short.

[0043] like Figure 7 As shown, the material pressing device 4 of this embodiment has a first limiting portion 18, and the positioning fixture 2 has a second limiting portion 20, and the second limiting portion 20 is arranged on the fixture platform 12 of the positioning fixture 2. The first limiting portion 18 and the second limiting portion 20 limit each other to define the circumferential position between the material pressing device 4 and the positioning fixture 2. Specifically, the first limiting portion 18 is a limiting groove, and the second limiting portion 20 is a limiting protrusion. When the edge material 7 is long enough, the edge material 7 will cover the limiting protrusion when it is laid flat on the fixture platform 12, and then when the limiting groove is sleeved on the limiting protrusion and fixed to each other, the edge material 7 covering the surface of the limiting protrusion will also be pressed to deform and fix, and then the position of the second workpiece 5 can be further fixed. In this embodiment, the first limit portion 18 and the second limit portion 20 make the positions of the pressing device 4, the second workpiece 5 and the positioning fixture 2 relatively static, ensuring that when the rotary table 8 rotates, the positioning fixture 2, the component to be processed, and the pressing device 4 can rotate synchronously, maintain precise synchronization, and improve the accuracy and stability of cutting. In addition, whether the first limit portion 18 and the second limit portion 20 are aligned can also detect whether the initial position of the rotary table 8 is in place, and a monitoring device can be configured on the second limit portion 20, which can only be started after the first limit portion 18 and the second limit portion 20 are in place, automatically completing the detection of the assembly position, and improving the level of automation.

[0044] like Figure 8-9As shown, the clamping device 9 and the pressing device 4 of this embodiment are jointly controlled by the first driving device 21 to enter and exit the processing station. In this embodiment, the clamping device 9 and the pressing device 4 can be jointly completed by the first driving device 21 to complete the advance and retreat, simplifying the assembly structure of the equipment, saving the use of the driving device, and reducing the manufacturing cost. The first driving device 21 of this embodiment includes a first moving device 22 that can move up and down and horizontally, and a grabbing device 23 that grabs the pressing device 4 and moves synchronously. In this embodiment, the grabbing device 23 is driven by the first moving device 22 to realize the grabbing of the pressing device 4, thereby carrying the pressing device 4, and the structure is simple and the operation is convenient. The gripping device 23 includes a first chuck 24 and a second chuck 25 that can move relatively and perform clamping and releasing actions. The inner sides of the first chuck 24 and the second chuck 25 have positioning posts 26 corresponding to the positioning holes 15. The cooperation between the positioning holes 15 and the positioning posts 26 can achieve the mutual fixation between the pressing device 4 and the gripping device 23. Furthermore, the inner clamping surfaces of the first chuck 24 and the second chuck 25 are configured as arc-shaped chucks 27 that match the annular groove 14 on the outer peripheral side of the pressing device 4, thereby improving the assembly firmness between the gripping device 23 and the pressing device 4 and effectively preventing the pressing device 4 from falling off from the gripping device 23 during transportation. In this embodiment, the first chuck 24 and the second chuck 25 are used to clamp the pressing device 4 during transportation and release it during processing, and the structure is simple and the operation is convenient. At the beginning, the first driving device 21 controls the pressing device 4 and the clamping device 9 to move horizontally together to the top of the positioning fixture 2 at the adjusted lifting height, and then descend to the processing station together. When descending, the pressing device 4 is sleeved on the outer periphery of the component to be processed of the assembly part 11 of the positioning fixture 2. After it is in place, the grasping device 23 releases the pressing device 4. At this time, the clamping device 9 remains outside the clamping station. At this time, the pressing device 4 and the clamping device have no interference with the rotation of the positioning fixture 2 with the rotating worktable 8.

[0045] like Figure 8-9 As shown, the clamping device 9 of this embodiment includes two clamping heads 28, and each clamping head 28 is controlled to enter and exit the clamping station by a second driving device 29. In this embodiment, the clamping head 28 is equipped with an independent second driving device 29 to control the entry and exit of the clamping station to achieve the clamping of the edge material 7, and cooperate to achieve automatic unloading, with a simple structure and convenient operation. At the same time, in order to enhance the clamping effect of the clamping head 28 on the edge material 7, the clamping surface of the clamping head 28 is provided with corrugated lines that increase the friction force. In this embodiment, two groups of second driving devices 29 are respectively assembled on the first clamping head 24 and the second clamping head 25, and the inner side of the first clamping head 24 and the second clamping head 25 is the clamping surface, and the outer side is equipped with the second driving device 29. In this embodiment, the second driving device 29 is a cylinder, that is, the cylinder is assembled on the outer side of the first clamping head 24 and the second clamping head 25, and the cylinder drives the clamping head 28 to enter and exit the clamping station (the first hole position 13 and the second hole position 17).

[0046] like Fig.10 As shown, the laser cutting machine of this embodiment further includes a detection device 19 for detecting the rotation data of the positioning fixture 2 and feeding it back to the control device. The detection device 19 is a photoelectric sensor, and the sensing baffle 30 is assembled on the bottom surface of the positioning fixture 2. This embodiment monitors the rotation data of the positioning fixture 2 and cooperates with the control device to realize the linkage of various devices, thereby improving the level of automation.

[0047] like Figure 5 As shown, in order to enhance the safety of the laser cutting machine, a baffle device 31 is configured, and the baffle device 31 includes a bracket 33 fixed on the upper surface of the mounting platform 32, and a magnet 34 is configured on the bracket 33, and a baffle 36 is assembled on the lower surface of the mounting platform 32 through a hinge 35. When the baffle 36 is closed, the baffle 36 is fixed to the magnet 34 by magnetic attraction.

[0048] The rotary table 8 of this embodiment has a mounting platform 32, on the bottom of which a servo motor 37 is mounted, and the output shaft of the servo motor 37 can be directly or through a reducer to be connected to the positioning fixture 2. The mounting platform 32 is mounted on a frame 38 through pillars.

[0049] Combination Figure 1-9 The embodiment of the present invention provides an operating method of a laser cutting machine for edge material. Compared with the prior art, it is not necessary to set up the anti-deflection and avoidance mechanisms in the prior art, thereby simplifying the operating steps of the equipment and improving the operating efficiency of the equipment. The operating method includes the following steps:

[0050] Step 1: fix the first workpiece 3 on the assembly portion 11 of the positioning fixture 2, and at the same time, the second workpiece 5 covers the outer surface of the first workpiece 3, and the edge material 7 of the second workpiece 5 is laid flat on the fixture platform 12;

[0051] Step 2: The material pressing device 4 is controlled by the first driving device 21 to enter the processing station, descend from above the first workpiece 3 and press the edge material 7 of the second workpiece 5 onto the fixture platform 12 of the positioning fixture 2;

[0052] Step 3: The laser cutting head 1 starts to emit laser to the cutting position 6 of the second workpiece 5, and the rotating table 8 simultaneously drives the positioning fixture 2, the pressing device 4, the first workpiece 3, and the second workpiece 5 to rotate. After the cutting is completed, the laser cutting head 1 and the rotating table 8 stop.

[0053] Step four, the clamping device 9 is controlled by the first drive device 21 to enter the processing station, and after the processing is completed, the laser cutting head 1 and the rotary table 8 are stopped, the clamping head 28 is controlled by the second drive device 29 to enter the clamping station to clamp the edge material 7 and the first drive device 21 sends it out of the processing station, and the pressing device 4 is lifted by the first drive device 21 from the positioning fixture 2 and exits the processing station.

[0054] Those skilled in the art should understand that the technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent.
