Description

Technical Field

[0001] The invention relates to a light shutter system, in particular to a light shutter system for laser welding. Background Art

[0002] There are many types of laser welding systems, most of which are laser welding systems based on spatial output light sources.

[0003] The launch port in the laser welding system needs to be inserted with an optical fiber when in use, and the launch port needs to be sealed when the model is changed, transferred or transported. The currently used optical sealing method is to seal with a manual plug rod or end cap, but this method has the following disadvantages: first, there is a risk of loss of the plug rod or end cap, which may require manual cleaning; second, if the system is frequently replaced or transferred, it will be very labor-intensive and have poor stability. Because there are many launch ports that need to be sealed, it is inevitable that the protection will be left exposed, which may reduce the service life of the laser system. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a light shutter system for laser welding, which can automatically seal the emission port, save time and effort, and has a long service life.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a shutter system for laser welding, comprising:

[0008] A sealing component is driven by the power unit to move laterally above the launching port, and the sealing component is provided with through holes corresponding to the plurality of launching ports;

[0009] A sensing component is arranged along the periphery of the emission port and is used to sense whether there is an optical fiber in the emission port;

[0010] Wherein, when the sensing component senses that an optical fiber is inserted into the emission port, the power unit drives the sealing component to move laterally so that the through hole and the emission port are arranged coaxially;

[0011] When the sensing component senses that no optical fiber is inserted into the launch port, the power unit drives the sealing component to move horizontally so that the through hole and the launch port do not overlap, and the launch port is sealed by the sealing component.

[0012] In one embodiment, the power unit is a driving cylinder, and a connecting plate that can move back and forth is provided on the piston rod of the driving cylinder, and the connecting plate is connected to the sealing component.

[0013] In one embodiment, the sealing component is a sealing plate in the shape of a long strip distributed along the emission port.

[0014] In one embodiment, the sensing component includes two opposing beam sensors disposed on both sides of the transmitting port and located on the upper surface of the coupling body; one is a transmitting sensor and the other is a receiving sensor.

[0015] In one embodiment, two limit blocks are provided at both ends of the sealing component to limit the position of the sealing component when it moves, and the two ends of the sealing component are clamped in the limit blocks at both ends.

[0016] In one embodiment, the number of the emission ports is five, and the five emission ports are linearly distributed on the coupling body.

[0017] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0018] The optical shutter system for laser welding of the present invention is provided with a sensing component at the emission port, which senses whether the optical fiber is inserted into the emission port through the sensing component, and then drives the sealing component to seal or open the emission port through the power unit to realize automatic sealing of the emission port when it is not working or changing or transferring, thereby saving manpower and material resources, improving the service life of the laser welding equipment, facilitating operation, improving the rate of changing and effective operation time, and improving the stability and safety of the system.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] The present invention provides a shutter system for laser welding to solve the problem that the prior art uses manual sealing of the emission port, which is time-consuming and labor-intensive, and the system has poor stability and safety and cannot meet the requirements of actual use.

[0027] For ease of understanding, the specific process in the embodiments of the present application is described below. Figures 1 to 4 In an embodiment of the present application, a light shutter system for laser welding includes a coupling body 1, a power unit 2, a sealing component 3 and a sensing component 4; the coupling body 1 has a plurality of launch ports 10 which are arranged through and into which optical fibers are inserted; the power unit 2 is arranged on the upper surface of the coupling body; the sealing component 3 is driven by the power unit 2 to move laterally above the launch port 10, and the sealing component 3 is provided with through holes 30 corresponding to the plurality of launch ports 10, wherein the aperture of the through holes 30 is not less than the aperture size of the launch port 10; the sensing component 4 is arranged along the periphery of the launch port 10, and is used to sense whether there is an optical fiber in the launch port 10.

[0028] The optical shutter system for laser welding of the present invention senses whether the optical fiber is inserted into the emission port 10 through the sensing component 4, and then drives the sealing component 3 through the power unit 2 to seal or open the emission port 10 to achieve automatic sealing of the emission port when it is not working or changing or transferring, saving manpower and material resources, increasing the service life of laser welding, and facilitating operation.

[0029] In one embodiment, see Figure 1 and Figure 3 The power part 2 is a driving cylinder, and a connecting plate 6 that can move forward and backward is provided on the piston rod of the driving cylinder 2, and the connecting plate 6 is connected to the sealing component 3 located on the upper surface of the coupling main body 1. When working, the driving cylinder drives the sealing component 3 to move horizontally above the launch port 10 through the connecting plate 6.

[0030] In one embodiment, see Figure 3 The sealing component 3 is a long strip-shaped sealing plate distributed along the emission port 10 .

[0031] In one embodiment, see Figures 1 to 3 The two ends of the sealing part 3 are provided with two stop blocks 5 for limiting the position of the sealing part 3 when it moves, and the two ends of the sealing part 3 are clamped in the stop blocks 5 at the two ends. In this way, the sealing part 3 will not be offset when driven by the power unit 2, thereby preventing the optical fiber from being unable to pass through the launch port 10 and the through hole 30.

[0032] In one embodiment, the sensing component 4 includes two opposing sensors disposed on both sides of the transmitting port 10 and located on the upper surface of the coupling body 1, one of which is an transmitting sensor 40 and the other is a receiving sensor 41. The transmitting sensor 40 and the receiving sensor 41 sense whether there is an optical fiber in the transmitting port 10 after mutually opposing each other.

[0033] In one embodiment, see Figure 4 The number of the emitting ports 10 is five, and the five emitting ports 10 are linearly distributed on the coupling main body 1; of course, the number may not be limited to the above five, and can be adjusted according to actual needs.

[0034] During operation, when the system receives an instruction to change the model, the lower servo will lift the fixture with the optical fiber. When the optical fiber reaches the launch port 10, the upper launch sensor 40 and the receiving sensor 41 will detect the presence of the optical fiber. At this time, the power unit 2 drives the sealing component 3 to move laterally, so that the launch port 10 and the through hole 30 are coaxially distributed, so that the optical fiber can be inserted into the launch port; when other fixtures are replaced, the lower servo disengages and drives the optical fiber away from the launch port 10. At this time, the launch sensor 40 and the receiving sensor 41 detect the signal that the optical fiber is absent, and the power unit 2 drives the sealing component 3 to move laterally, and uses the sealing component 3 to seal the top of the launch port 10, thereby effectively protecting the launch port 10.

[0035] In addition, when the laser welding equipment needs to be transported or moved, the transmitting sensor 40 and the receiving sensor 41 do not sense the presence of the optical fiber. Therefore, the sealing component 3 automatically seals the transmitting port 10 under the drive of the power unit, thereby saving manpower and material resources, and can effectively seal the transmitting port 10, thereby increasing its service life.

[0036] In summary, the shutter system for laser welding of the present invention effectively solves the cleaning problems encountered during the shipment or transfer of synchronous laser welding equipment and the jig change process, effectively prolongs the service life of the laser welding system, saves labor maintenance costs, increases the rate of changeover and effective operation time, and improves the stability and safety of the system.

[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
