[0037] This application discloses a laser processing apparatus, with reference to... Figure 1-6 The laser processing device includes: a rotating mechanism 20, including a rotating base 21 and a plurality of feeding bins 22 disposed on the rotating base 21, the feeding bins 22 being arranged around the rotation center; a lifting mechanism 30, including a material lifting component 32 and a lifting drive component 31, the lifting drive component 31 being used to drive the material lifting component 32 through the rotating base 21 and into the feeding bins 22; a laser engraving mechanism, including a marking head 41 disposed above the rotating base 21; and a material unloading mechanism 50, including a material unloading robot arm disposed on one side of the rotating base 21.

[0038] In this embodiment, multiple feeding bins 22 can each hold workpieces of different specifications, and the workpieces are stacked in the feeding bins 22. The rotating base 21 can drive each feeding bin 22 to move below the marking head 41, thereby enabling the processing of workpieces of various specifications. The lifting drive 31 located below the rotating base 21 can drive the top material component 32 to rise. The top material component 32 passes through the rotating base 21 and enters the feeding bin 22 from the bottom, lifting the workpieces in the feeding bin 22 as a whole until the workpiece at the top of the feeding bin 22 is lifted to a set height. The laser engraving mechanism includes a marking head 41 located above the rotating base 21, which can mark the workpiece at the top of the feeding bin. The unloading mechanism 50 includes an unloading robot arm located on one side of the rotating base 21, which can transfer the laser-engraved workpieces to a set area.

[0039] Furthermore, the feeding bin 22 can hold workpieces of different specifications. The rotating mechanism 20 may also include a DD motor and a position sensor 23. The DD motor drives the rotating base 21 to rotate, which can rotate the feeding bin 22 corresponding to the workpiece to be processed to the marking position, which is the position directly below the marking head 41. The position sensor 23 can sense the position status of each feeding bin 22. At the control level, it can transmit the position signal of the feeding bin 22 to the control system, which then controls the rotating base 21 to rotate, so that the target feeding bin 22 moves to the aforementioned marking position.

[0040] In some embodiments, the feeding bin 22 includes a mounting base 28 and limiting members 24 vertically disposed on the mounting base 28. Multiple limiting members 24 form a receiving space for accommodating workpieces. The mounting base 28 also has a through hole through which a top feeding member 32 passes. The mounting base 28 also has an adjustment hole, with the lower end of each limiting member 24 disposed in the adjustment hole, allowing the spacing between the limiting members 24 to be adjusted. The mounting base 28 also has a foolproof positioning member 25 adapted to the workpiece, which is disposed within the receiving space.

[0041] In this embodiment, workpieces are loaded into the feeding bin 22 in a stacked manner. The rotating seat 21 and mounting base 28 are each provided with corresponding through holes, allowing the top material 32 to pass through. The aforementioned limiting member 24 can be an angle steel arranged at four corners, mainly used to limit the four corners of the workpiece, or it can be a limiting rod that limits the four sides of the workpiece. When the workpiece is loaded and lifted, the limiting member 24 serves as a guide and limiter. The foolproof positioning member 25 can be a positioning rod that matches the positioning hole on the workpiece, preventing the workpiece from being misplaced in the corresponding feeding bin 22. The mounting base 28 is provided with elongated adjustment holes, specifically including longitudinal and transverse adjustment holes. The position of the limiting member 24 in the adjustment holes can be adjusted. The spacing of the limiting members 24 can be adjusted according to the size of the workpiece to accommodate different specifications. Additionally, a scale plate 26 can be provided on the mounting base 28, located outside the limiting member 24, allowing the user to visually see the number of workpiece stacks based on the scale. The mounting base 28 is also provided with a foolproof positioning pin hole 27 to prevent the feeding bin 22 from being placed in the wrong position. The mounting base 28 is provided with a positioning pin corresponding to the aforementioned foolproof positioning pin hole 27. The mounting base 28 is engraved with numbers that correspond one-to-one with the rotating base 21 to further assist in the installation of the mounting base 28.

[0042] In some embodiments, the laser processing apparatus further includes a vision camera disposed on one side of the marking head 41. The vision camera is used to acquire image information of the workpiece below and perform visual inspection. The visual inspection mainly compares the workpiece model corresponding to the work order with the workpiece drawing in the acquired image information to check whether the workpiece to be processed is consistent with the workpiece on the work order, and the processing quality of the workpiece surface after processing. The laser processing apparatus also includes a drive module 42 for driving the vision camera and the marking head 41. The drive module 42 drives the marking head 41 to rise and fall to achieve laser adjustment to optimal focus, the light source compensates for the illumination of the vision camera, the vision camera identifies and positions the marking of the workpiece surface features, the processing effect of the workpiece is detected after marking is completed, and the suction pipe sucks away the dust generated during laser engraving on the workpiece surface.

[0043] In some embodiments, a plurality of recycling bins 60 are provided on one side of the unloading robot. The recycling bins 60 are used to recycle workpieces of different specifications, and the recycled workpieces are finished and qualified. The recycling bin 60 includes: a housing 61 with a feeding port at the top, a door 64 on the side, and a lock body 65 for locking the door 64; a drawer 62 slidably disposed within the housing 61 and located near the inner bottom surface of the housing 61; and a material box 63 disposed within the drawer 62, with an inlet corresponding to the feeding port at its top. The recycling bin 60 also includes a first sensor 66 and a second sensor 67 disposed on the inner wall of the housing 61. The first sensor 66 detects the position of the material box 63, and the second sensor 67 is disposed above the first sensor 66 and detects the stacking height of the workpieces in the material box 63.

[0044] The laser processing device can be equipped with five recovery bins 60, which can receive workpieces of different specifications according to the processing requirements of the work order. The housing 61 houses a drawer 62, a material box 63, a lock body 65, a slide rail, and a feeding funnel. The material box 63 is placed on the drawer 62 to receive workpieces that have been laser-engraved. The first sensor 66 can be a proximity switch used to sense the position of the drawer 62. When the material box 63 is full, the second sensor 67 can send a signal back to the control system indicating that the material box 63 is full. The second sensor 67 can be a photoelectric switch; when the material box 63 is full, the light signal of the photoelectric switch can be blocked, causing a change in the received signal. When the material box 63 is full, the control system can send corresponding information to the user.

[0045] The laser processing device also includes a control module electrically connected to the lock body 65, and a barcode scanner 80 electrically connected to the control module. The control module is used to control the lock body 65 to open based on the barcode information obtained by the barcode scanner 80. The lock body 65 is an electronic lock. During processing, the material box 63 is in a locked state. The control module can be a part of the aforementioned control system's functional modules. When the recycling bin 60 is full or the work order requirement is completed, the recycling bin 60 will be locked. The corresponding recycling bin 60 will be automatically opened by scanning the QR code on the work order, ensuring that the wrong material is retrieved.

[0046] In some embodiments, the actuator 51 of the unloading robot is provided with a mounting member 52, which may be a mounting plate. A suction member 53 is provided on the lower side of the mounting member 52, which may be a vacuum suction cup. A third sensor is also provided on the mounting member 52 for detecting the workpiece picked up by the suction member 53. The laser processing device also includes an anti-adhesion mechanism 70, which includes: an air nozzle 73, located on one side of the rotating base 21 and below the marking head 41; and an air blowing drive member 71 for driving the air nozzle 73 to move toward the center of rotation.

[0047] The feeding mechanism 50 can separate different workpieces according to system settings, removing the workpieces from the feeding bin 22. Simultaneously, the anti-sticking mechanism 70 activates to prevent workpiece sticking. The air-blowing drive 71 can be a horizontally positioned cylinder. Specifically, a mounting bracket 72 can be mounted on the cylinder's push rod. A notch is provided on one side of the mounting bracket 72, into which the feeding bin 22 can enter. The air nozzle 73 can be mounted on the mounting bracket 72, and a fourth sensor 74 can also be mounted on the mounting bracket 72 for sensing the workpiece. When the feeding bin 22 reaches the marking position, the air-blowing drive 71 drives the mounting bracket 72 towards the feeding bin 22, causing the feeding bin 22 to enter the notch. The fourth sensor 74 and the air nozzle 73 are respectively located on the inner sidewall adjacent to the notch, and the air nozzle 73 and the fourth sensor 74 can move with the mounting bracket 72 to the side of the feeding bin 22. After the laser engraving of the workpiece is completed, the unloading mechanism 50 moves the mounting part 52 onto the workpiece. At this time, the suction part 53 is facing the workpiece, and the vacuum generator starts to work to attract the workpiece. When the workpiece is lifted by the suction part 53, the third sensor determines whether the workpiece is present. When the workpiece is lifted to a certain height and is detected by the fourth sensor 74, the air nozzle 73 can blow air onto the workpiece to prevent the top two layers of workpiece from sticking together. When the workpiece is lifted by the suction part 53, the third sensor can also detect the lifting status of the workpiece in real time and provide feedback on the status after the material is released.

[0048] This application also proposes a laser processing equipment, including a laser processing apparatus and a frame 10 for mounting the laser processing apparatus. The frame 10 includes a frame body and a base plate 11 disposed on the upper side of the frame body. The aforementioned rotating mechanism 20, laser engraving mechanism, unloading mechanism 50, and recovery bin 60 are respectively disposed on the base plate 11, and the lifting mechanism 30 is disposed below the base plate 11. The base plate 11 is provided with corresponding through holes for the lifting member 32 to pass through. In addition, a defective product bin 69 can be provided on the base plate 11 for placing workpieces that are defective upon arrival or whose processing quality is unacceptable.

[0049] In this embodiment, the working principle of the laser processing device and equipment is as follows: The rotating mechanism 20 rotates the stacked workpieces in batches directly below the laser engraving mechanism. The lifting mechanism 30 lifts the workpieces, placing the top layer at a set height. The laser engraving mechanism then emits light to engrave the surface of the workpieces. Once the first workpiece is laser-engraved, the unloading mechanism 50 removes it and places it into the corresponding recycling bin 60. During unloading, the anti-adhesion mechanism 70 activates, blowing air onto the top layer of workpieces to prevent adhesion to the workpieces below. If the laser-engraved workpiece's precision and content do not meet requirements, the unloading mechanism 50 places the defective workpiece into the defective bin 69. After all workpieces according to the work order specifications and batches are laser-engraved, the barcode scanner 80 scans the incoming material code on the work order, opening the door 64 of the recycling bin 60 corresponding to the work order, allowing the removal of the acceptable workpieces.

[0050] The laser processing apparatus and equipment in this embodiment are compatible with workpieces of different specifications. The spacing of the limiting members 24 can be adjusted to accommodate workpieces of different specifications. It can intelligently process workpieces of different specifications according to different work orders. This device also has excellent error-proofing measures. From loading and laser engraving to unloading, its feeding bin uses one-to-one mechanical positioning for error-proofing, and a vision camera is used for visual error-proofing during laser engraving. During unloading, the corresponding recycling bin 60 needs to be opened according to the work order scan to avoid incorrect material retrieval. The probability of mixed or incorrect materials is reduced to zero. For workpiece stacking anti-sticking measures, the anti-sticking mechanism 70 blows air simultaneously at the moment the suction cup picks up the workpiece to prevent it from sticking. This device integrates the loading mechanism, lifting mechanism 30, laser engraving mechanism, unloading mechanism 50, and anti-sticking mechanism 70, greatly improving work efficiency and enabling automated production.
