Description

Technical Field

[0001] The present invention relates to the technical field of laser processing, in particular to a laser processing double-station switching platform with a protection structure and a protection method thereof. Background Art

[0002] The laser processing dual-station switching platform is a processing equipment that uses a laser beam for welding. It can set up two laser processing stations on the same device to complete different welding tasks respectively. The laser processing dual station can also complete different processing tasks on the same device, avoiding the time waste of equipment replacement and movement, and greatly improving production efficiency. In addition, the laser processing dual station only needs to occupy one device and can complete the processing tasks of two stations at the same time, saving factory space. Since a disc structure is used to support the laser processing loading platform, the disc needs to rotate when switching stations, so a large gap is left between the laser processing loading platform with a disc structure and the base. During operation, the upper laser processing pressing mechanism presses down the laser processing loading platform to fix the laser processing workpiece, causing the laser processing loading platform to deform, and both the rotating shaft and the motor are affected. Summary of the Invention

[0003] The purpose of the present invention is to provide a laser processing dual-station switching platform with a protective structure and a protection method thereof, so as to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a laser processing double-station switching platform with a protective structure, comprising a laser welding base, a motor installed at the bottom of the laser welding base, an output end of the motor fixedly connected to a motor shaft, the motor shaft passes through the laser welding base and extends to the top of the laser welding base, and is connected to a processing station mounting disc, the processing station mounting disc is located above the laser welding base, and a No. 1 processing worker loading platform and a No. 2 processing worker loading platform are provided on the top of the processing station mounting disc.

[0005] Preferably, the No. 1 processing worker loading platform and the No. 2 processing worker loading platform both have four pillar internal supports, which are fixed to the processing station mounting disc through pillar outer shells, and the pillar outer shells have built-in pillar telescopic parts. The No. 1 processing worker loading platform and the No. 2 processing worker loading platform are symmetrically arranged on both sides with the center of the processing station mounting disc as the center, and the workpiece to be processed is installed on the top of the No. 1 processing worker loading platform and the No. 2 processing worker loading platform.

[0006] Preferably, a pressing device is provided on the top of the laser welding base, and the pressing device specifically includes two connecting plates, a top plate is installed between the connecting plates, four guide pillars are provided on the top plate, and a pressing cylinder is provided between the four guide pillars, the piston rod of the pressing cylinder passes through the top plate and extends to the bottom of the top plate, and is connected to the pressing plate, and a buffer pad is provided at the bottom of the pressing plate, and the buffer pad is used to reduce the impact on the workpiece during the pressing process. The pressing plate is installed with a pressing seat through the buffer pad, and the pressing seat is in contact with the workpiece to be processed.

[0007] Preferably, a laser processing device is provided in front of the top plate.

[0008] Preferably, four guide pillars pass through the top plate and are connected to the pressing plate, and protective plates are provided on the tops of the four guide pillars.

[0009] Preferably, the pressing plate is equipped with a pressing sensor for real-time monitoring of the pressing force.

[0010] Another technical problem to be solved by the present invention is to provide a protection method for the laser processing dual-station switching platform as described above, comprising the following steps: Step 1, load the workpiece to be processed on the No. 1 processing loading platform, drive the motor shaft through the motor, and the motor shaft drives the processing station mounting disc to rotate to the processing station position, load the workpiece to be processed on the No. 2 processing loading platform, and at the same time press the device downward, the No. 1 processing loading platform is subjected to force, the four pillar inner supports move downward, the pillar shell is fixed on the processing station mounting disc and does not move, the four pillar inner supports move downward until the pillar telescopic part rests on the laser welding base, and the pressing device continues to pressurize to the set pressure value. At this time, all the pressure is borne by the pillar inner supports and the laser welding base, while the No. 1 processing loading platform, the processing station mounting disc, the motor and the motor shaft are not subjected to force, which plays a protective role; Step 2. When the workpiece to be processed on the No. 1 processing worker loading platform is processed, the pressing device moves up, the force on the No. 1 processing worker loading platform is released, the internal rebound device of the four pillars works, and the four pillars internal supports move up until the telescopic part of the pillars rebounds completely and leaves the laser welding base.

The motor shaft 6 passes through the laser welding base 1 and extends above the laser welding base 1 and is connected to the processing station mounting disc 2. The processing station mounting disc 2 is located above the laser welding base 1. The top of the processing station mounting disc 2 is provided with a first processing worker loading platform 4 and a second processing worker loading platform 5; The No. 1 processing worker loading platform 4 and the No. 2 processing worker loading platform 5 each have four pillar inner supports 10, which are fixed to the processing station mounting disc 2 through a pillar housing 9. The pillar housing 9 has a pillar telescopic portion 11 built into it. The No. 1 processing worker loading platform 4 and the No. 2 processing worker loading platform 5 are symmetrically arranged on both sides with the center of the processing station mounting disc 2 as the center. The workpiece 8 to be processed is installed on the top of the No. 1 processing worker loading platform 4 and the No. 2 processing worker loading platform 5; The top of the laser welding base 1 is provided with a pressing device 3, which specifically includes two connecting plates 31, a top plate 32 is installed between the connecting plates 31, four guide pillars 33 are provided on the top plate 32, and a pressing cylinder 34 is provided between the four guide pillars 33, the piston rod of the pressing cylinder 34 passes through the top plate 32 and extends to the bottom of the top plate 32 and is connected to the pressing plate 35, a buffer pad is provided at the bottom of the pressing plate 35, the buffer pad is used to reduce the impact on the workpiece during the pressing process, the pressing plate 35 is installed with a pressing seat 36 through the buffer pad, and the pressing seat 36 contacts the workpiece 8 to be processed, a laser processing device is provided in front of the top plate 32, four guide pillars 33 pass through the top plate 32 and are connected to the pressing plate 35, and a protective plate is provided on the top of the four guide pillars 33, which can effectively prevent the damage to the guide pillars 33 by splashes generated during laser processing, and the pressing plate 35 has a built-in pressing sensor 37 for real-time monitoring of the pressing force; The pressing and releasing of the workpiece 8 to be processed is achieved by the extension and contraction of the pressing cylinder 34. The motor 7 drives the motor shaft 6 to rotate, driving the processing station mounting disc 2 to switch the processing station, thereby realizing the alternating use of the No. 1 processing loading platform 4 and the No. 2 processing loading platform 5, thereby improving the processing efficiency and ensuring the workpiece processing accuracy.

[0020] In addition, the present invention also proposes a protection method for a laser processing dual-station switching platform, comprising the following steps: Step 1, load the workpiece 8 to be processed on the No. 1 processing loading platform 4, drive the motor shaft 6 through the motor 7, and the motor shaft 6 drives the processing station mounting disc 2 to rotate to the processing station position, load the workpiece 8 to be processed on the No. 2 processing loading platform 5, and at the same time press the pressing device 3 downward, the No. 1 processing loading platform 4 is subjected to force, the four pillar inner supports 10 move downward, the pillar shell 9 is fixed on the processing station mounting disc 2 and does not move, the four pillar inner supports 10 move downward until the pillar telescopic part 11 rests on the laser welding base 1, and the pressing device 3 continues to pressurize to the set pressure value. At this time, all the pressure is borne by the pillar inner supports 10 and the laser welding base 1, while the No. 1 processing loading platform 4, the processing station mounting disc 2, the motor 7 and the motor shaft 6 are not subjected to force, which plays a protective role; Step 2. When the workpiece 8 to be processed on the No. 1 processing worker loading platform 4 is processed, the pressing device 3 moves up, the force on the No. 1 processing worker loading platform 4 is withdrawn, the rebound device in the four pillar inner supports 10 works, and the four pillar inner supports 10 move up until the telescopic part 11 of the pillar rebounds completely and leaves the laser welding base 1. The four pillar inner supports 10 and the laser welding base 1 return to their original positions. The processing station mounting disc 2 will not be subjected to the pressure of the pressing device 3 at this time and maintains balance. The motor 7 drives the motor shaft 6 to rotate, and the No. 1 processing worker loading platform 4 and the No. 2 processing worker loading platform 5 complete the station switching. The No. 1 processing worker loading platform 4 unloads the processed workpiece 8 and reloads the workpiece 8 to be processed. At the same time, the pressing device 3 is pressed down, the No. 2 processing worker loading platform 5 is subjected to force, and the pillar inner supports 10 are pressed down, and the above processing actions are repeated.

[0021] In summary, the processing station mounting disc 2 is fixed in the middle on the motor shaft 6, and a certain gap is left between the processing station mounting disc 2 and the laser welding base 1. The motor 7 drives the processing station mounting disc 2 on the motor shaft 6 to switch the working position; The laser processing platform is secured to the laser station switching platform by four columns. These columns feature a resilient, retractable structure. During operation, the upper laser processing pressing mechanism presses down on the laser processing platform. The bottoms of the four telescopic columns below the laser processing platform extend downward and press against the bottom, securing the platform. During this process, the laser station switching disc is not subjected to pressure from the upper pressing mechanism, and thus the motor and shaft are also unaffected, thus protecting the laser station switching mechanism.
