Abstract

Technical Field

[0002] In the field of existing laser processing equipment, in order to meet the processing needs of multiple stations, a dual-laser architecture is often used to achieve synchronous processing at multiple stations. However, existing dual-laser systems are often linearly arranged, with the left and right lasers installed parallel to each other on the base, and the optical path is guided to different stations by a set of reflectors. However, the reflectors only use single-stage steering, and the adjustment of the optical path angle is limited, resulting in a large positioning error in the processing area. At the same time, this layout also has the following defects: (1) The linear layout expands laterally, resulting in low space utilization. (2) There is a lack of tolerance compensation, resulting in insufficient optical path guidance accuracy. (3) Heat dissipation and stability are limited, and there are defects such as thermal crosstalk causing beam distortion, making it difficult to balance the efficiency and accuracy of multi-station processing.

[0033] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0034] like Figure 1 The dual-laser stacked architecture includes a mounting base 1, which is unique in that a lifting and positioning component is mounted on the mounting base 1, and a right laser 2 is mounted on the lifting and positioning component. Simultaneously, the optical path output end of the right laser 2 is connected to a right-side primary guide device and a right-side secondary guide device. This allows for multi-angle optical path guidance, achieving precise optical path guidance. Specifically, the right-side primary guide device includes an adjustment bracket 3 connected to the mounting base 1. A third reflector frame 4 is mounted on the upper end of the adjustment bracket 3 at the optical path output end of the right laser 2, and a fourth reflector frame 5 is mounted on the adjustment bracket 3 at the optical path output end of the third reflector frame 4. This enables the initial redirection guidance of the optical path. Furthermore, the right-side secondary guide device includes a fifth reflector frame 6 and a sixth reflector frame 7 connected by optical paths, with the optical path output end of the fourth reflector frame 5 corresponding to the optical path input end of the fifth reflector frame 6. This enables secondary redirection guidance of the optical path, and through a specific angle set by the sixth reflector frame 7, it reaches the appropriate area position. Considering the dual-optical-path distribution formed by the two lasers, the optical-path output end of the sixth reflector frame 7 constitutes the first processing station.
[0035] During implementation, a left laser 8 is also installed on the mounting base 1, and a left-side guide device is installed at the optical path output end of the left laser 8. This satisfies the guidance adjustment of the output optical path of the left laser 8. Specifically, the left-side guide device consists of a first reflector frame 9 and a second reflector frame 10 with interconnected optical paths. During assembly, the optical path input end of the first reflector frame 9 corresponds to the optical path output end of the left laser 8. Simultaneously, the optical path output end of the second reflector frame 10 constitutes a second processing station. This allows the right laser 2 and the left laser 8 to be arranged in a straight line but with different optical paths, achieving dual-station processing and minimizing the space occupied by the laser processing equipment. Furthermore, both the left laser 8 and the right laser 2 are picosecond lasers or high-power continuous lasers. This allows for the selection of appropriate lasers according to actual needs, meeting different processing requirements.
[0036] In a preferred embodiment of this invention, a laser support plate is used as the lifting and positioning component. This includes paired support frames 11 connected to the mounting base 1. The support frames 11 are connected to a support plate 12 via adjusting screws. Several locking strips are distributed on the front of the support plate 12, and corresponding slots are distributed at the bottom of the right laser 2, with the locking strips embedded in the slots. This ensures stable placement of the right laser 2, preventing displacement after installation. To avoid any tolerance affecting the preset angle of the output optical path of the left laser 8, an elastic adjusting washer made of silicone rings or a metal washer made of stainless steel can be inserted between the adjusting screws and the support frames 11. This adjusts or fills any tilting gaps caused by tolerances, ensuring that the output optical path of the left laser 8 is horizontal after installation. Furthermore, to ensure the horizontality of the support plate 12 during assembly, horizontal calibration scales are marked on the edge of the support plate 12, or a bubble level is installed on the edge of the support plate 12. In this way, during later maintenance, users can promptly check the current levelness of the support plate 12 for quick calibration. Furthermore, considering the heat dissipation requirements for long-term operation, a heat dissipation mechanism consisting of heat sink fins is distributed at the bottom of the support plate 12. If a low-power right laser 2 is selected, several strip-shaped heat dissipation holes can be directly opened on the plate for heat dissipation through airflow.
[0037] Furthermore, to ensure effective optical path guidance, the adjustment bracket 3 used in this invention includes a bracket body with an inlet hole at its upper end. This inlet hole aligns with the optical path output end of the right laser 2. A connecting block 13 is installed on one side of the inlet hole, and a third reflector frame 4 is bolted to the connecting block 13. This allows the optical path emitted from the right laser 2 to be directly and non-destructively guided into the third reflector frame 4. The connecting block 13 ensures stable installation of the third reflector frame 4. During implementation, the connecting block 13 can be bolted to the bracket body and also bolted to the third reflector frame 4. Simultaneously, several mounting holes 17 are distributed on the bracket body, and adapter brackets 14 are bolted to the mounting holes 17. A fourth reflector frame 5 is bolted to the adapter brackets 14. For ease of adjustment, eccentric bolts can be used to adjust and lock the actual installation orientation and angle of the third reflector frame 4 and the fourth reflector frame 5, achieving effective optical path guidance.
[0038] In practical implementation, the lower end of the sixth reflector mount 7 is connected to the mounting base 1 via an extension bracket 15. Height scales are vertically distributed on the outer side of the extension bracket 15. Simultaneously, the bottom of the extension bracket 15 is connected to the mounting base 1 via a horizontal alignment stud. This allows adjustment of the final optical path angle of the sixth reflector mount 7. Furthermore, this invention includes independent height adjustment blocks 16 installed below the fifth reflector mount 6, the left laser 8, the first reflector mount 9, and the second reflector mount 10. These height adjustment blocks 16 are screwed to the mounting base 1. After assembly, a raised gap is formed between the height adjustment block 16 and the upper end of the mounting base 1. Several heat dissipation fins are installed within this raised gap for effective heat dissipation. Considering the need for active heat dissipation under high operating conditions, several water-cooling pipes can also be installed within the raised gap. These water-cooling pipes are copper serpentine pipes, with their inlets connected to an external circulating cooling system.
[0039] Furthermore, considering the need for subsequent installation of other accessories, functional expansion is possible. Several mounting holes 17 are distributed on the upper end and sides of the mounting base 1. Specifically, the mounting holes 17 are threaded holes, allowing for the fixing of corresponding accessories by screwing in suitable screws or bolts. Simultaneously, considering the need for displacement adjustment during the installation of certain components, the mounting holes 17 can also be elongated holes, with a sliding nut embedded within them. Thus, during installation, the workpiece is positioned appropriately using the sliding nut, and then the sliding nut is tightened.
[0040] During implementation, considering the control stability of the left laser 8 and the right laser 2, a synchronization modulation module can be connected to the control terminals of the left laser 8 and the right laser 2. Specifically, the synchronization modulation module is an electro-optic modulator or an acousto-optic modulator, used to achieve pulse timing synchronization between the two lasers.
[0041] The working principle of this utility model is as follows: Both the left laser 8 and the right laser 2 are adapted to independent first and second processing stations. By adjusting their power, they can meet the requirements of synchronous processing at both stations. Alternatively, the left laser 8 can be used to process a certain surface of a workpiece. The processed workpiece can then be placed into the first processing station by a transport device to achieve multi-angle laser processing of other surfaces.
[0042] Furthermore, considering ease of implementation, the reflector frame brand can be Soleb, and the laser brand can be Ingo Laser. Of course, other suitable brands or models can also be selected, which will not be elaborated further.

They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
