Description

Technical Field

[0001] The present application relates to the technical field of laser welding, and particularly relates to a laser room and a laser welding system. Background Art

[0002] Laser welding is a method of welding by using the heat generated by bombarding a workpiece with a focused laser beam as a high-energy density energy source. Due to the optical properties of laser such as refraction and focusing, laser welding is very suitable for welding of micro parts and parts with very poor accessibility. During the laser welding process, inevitable laser radiation will be generated. In order to prevent the laser radiation from causing harm to the surrounding environment and personnel, laser welding needs to be carried out in a laser room with certain protection and light shielding requirements.

[0003] However, during the process of sequentially welding multiple welded parts in the laser room, when replacing the previous welded part with the next one after the welding of the previous welded part is completed, it is necessary to first stop the welding mechanism, then open the door of the laser room. After the replacement is completed and the closing action of the door is in place, laser welding can be carried out to prevent laser leakage and external radiation caused by welding without closing the door. However, this makes the welding mechanism unable to continuously weld during the welding process of multiple welded parts, resulting in a significant reduction in production efficiency. Summary of the Invention

[0004] Based on this, it is necessary to provide a laser room and a laser welding system for the problem that during the welding process of multiple welded parts in the existing laser room, the welding mechanism cannot continuously weld, resulting in a significant reduction in production efficiency.

[0013] When a plurality of the sliding tables pass through the main body of the laser room simultaneously, the second light-shielding plate of one of the sliding tables close to the feeding port is engaged with the sealing mechanism on the side of the feeding port, and the first light-shielding plate of another sliding table close to the discharging port is engaged with the sealing mechanism on the side of the discharging port.

The mounting seat is fixed to the sealing frame, the blade is rotatably connected to the mounting seat, the rotation axis of the blade is perpendicular to the first direction, and one side of the blade close to the light-shielding plate is parallel to the rotation axis;

[0016] When the sliding table moves in the feeding direction along the first direction, each side of the light-shielding plate can respectively contact the blades of the sealing components and push the blades to rotate in the first clockwise direction.

[0017] In one embodiment, the sealing component further includes a first elastic member. The mounting seat includes a first rotation groove. The first elastic member is arranged between the first rotation groove and the blade. The first elastic member has a tendency to make the blade rotate in the second clockwise direction for resetting the blade, wherein the second clockwise direction is opposite to the first clockwise direction.

[0018] In one embodiment, the sealing component further includes a first limiting member, and the first limiting member is used for limiting the rotation angle of the blade to one side in the second clockwise direction;

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0047] In a first aspect, referring to Figures 1-3 , an embodiment of the present application provides a laser room, which includes a laser room main body 1, a sealing mechanism 2, a conveying track 3 and a sliding table 4. Feed ports and discharge ports are respectively formed at both ends of the laser room main body 1; a plurality of sealing mechanisms 2 arranged in a first direction are fixedly provided at the feed port and the discharge port of the laser room main body 1, and are hermetically engaged between adjacent two sealing mechanisms 2; the conveying track 3 penetrates through the laser room main body 1, and both ends of the conveying track 3 respectively extend out of the feed port and the discharge port, and the first direction is the extending direction of the conveying track 3; the sliding table 4 is slidably connected to the conveying track 3, the sliding table 4 is used for carrying the workpiece to be welded, and one light shielding plate 41 is respectively arranged at both ends of the sliding table 4 along the first direction. Among them, during the process of the sliding table 4 sliding along the conveying track 3, one of the two light shielding plates 41 can be hermetically engaged with each sealing mechanism 2 in sequence.

[0048] In the laser room provided by the embodiment of the present application, during the process of the sliding table 4 sliding along the conveying track 3, when one of the two light shielding plates 41 is hermetically engaged with the sealing mechanism 2, the other light shielding plate 41 can be located inside the laser room main body 1. Among them, among the two light shielding plates 41, the light shielding plate 41 hermetically engaged with each sealing mechanism 2 can block the welding laser from leaking outside the laser room main body 1, and the other light shielding plate 41 located inside the laser room main body 1 can also block the welding laser from leaking outside the laser room main body 1 at the same time. In this way, during the process of replacing the workpiece to be welded, when the sliding table 4 slides in and out of the laser room main body 1 along the conveying track 3, the common blocking of the two light shielding plates 41 and the sealing mechanism 2 can block the laser from leaking outside the laser room main body 1, so that the welding process can be carried out continuously without stopping to replace parts, thereby greatly improving the production efficiency.

[0049] Such as Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, the laser room includes a plurality of sliding tables 4, which are arranged in sequence along the conveying track 3; two light shielding plates 41 at both ends of each sliding table 4 are respectively defined as a first light shielding plate 411 and a second light shielding plate 412. The first light shielding plate 411 is located on one side of the sliding table 4 close to the feeding end of the conveying track 3, and the second light shielding plate 412 is located on one side of the sliding table 4 close to the discharging end of the conveying track 3; when a plurality of two sliding tables 4 pass through the laser room main body at the same time, the second light shielding plate 412 of one of the sliding tables 4 close to the feeding port engages with the sealing mechanism 2 on one side of the feeding port, and the first light shielding plate 411 of the other sliding table 4 close to the discharging port engages with the sealing mechanism 2 on one side of the discharging port.

[0050] In this embodiment, when two adjacent sliding tables 4 pass through the laser room main body at the same time, the second light shielding plate 412 of one of the sliding tables 4 and the first light shielding plate 411 of the other sliding table 4 can respectively block the sealing mechanism 2 on one side of the feeding port and the sealing mechanism 2 on one side of the discharging port, so that a closed space is formed by enclosing the laser room main body 1, the sealing mechanism 2, the second light shielding plate 412 of one of the two adjacent sliding tables 4 and the first light shielding plate 411 of the other sliding table 4, thereby avoiding laser leakage to the outside of the laser room main body 1.

[0051] In addition, by arranging a plurality of sliding tables 4, the workpieces to be welded can continuously enter the laser room main body 1, so that during the welding process of a plurality of workpieces to be welded, the workpieces to be welded can be continuously welded, greatly improving the production efficiency.

[0052] It can be understood that a plurality of workpieces to be welded are arranged on each sliding table 4, and the workpieces to be welded are located at the welding position of the welding mechanism during welding. When the previous workpiece to be welded is welded, the sliding table 4 moves along the feeding direction, so that the next workpiece to be welded can be moved to the welding position to realize the replacement of the workpiece to be welded.

[0053] For example, when two sliding tables 4 pass through the laser room main body 1 at the same time, the second light shielding plate 412 of one sliding table 4 engages with the sealing mechanism 2 of the feeding port, and the first light shielding plate 411 of the other sliding table 4 engages with the sealing mechanism 2 of the discharging port, enclosing a closed space. At this time, the sliding table 4 with the first light shielding plate 411 engaged with the sealing mechanism 2 of the discharging port is still located in the laser room main body 1 for welding.

[0054] For example, when three sliding tables 4 pass through the laser room main body 1 at the same time, they are the first sliding table, the second sliding table and the third sliding table in sequence along the conveying direction of the conveying track 3. The second light shielding plate 412 of the first sliding table engages with the sealing mechanism 2 of the feeding port, the first light shielding plate 411 of the third sliding table engages with the sealing mechanism 2 of the discharging port, enclosing a closed space, and the second sliding table is located in the laser room main body 1 for welding at this time.

[0055] And so on, the cases of specifically setting four sliding tables 4 and more than four sliding tables 4 will not be elaborated here.

[0056] In some embodiments, when there is only one sliding table 4 on the conveying track 3, during the feeding process of the sliding table 4, the first light blocking plate 411 engages with the sealing mechanism 2 on one side of the feeding port, and the second light blocking plate 412 is located inside the main body 1 of the laser room, which can block the leakage of laser from the discharging port; during the discharging process of the sliding table 4, the second light blocking plate 412 first leaves the discharging port and engages with the sealing mechanism 2 on one side of the discharging port. At this time, the first light blocking plate 411 is located inside the main body 1 of the laser room, which can block the leakage of laser from the feeding port. Thus, when there is only one sliding table 4 on the conveying track 3, during the process of the sliding table 4 sliding in and out of the main body 1 of the laser room along the conveying track 3, the light blocking plate 41 and the sealing mechanism 2 can also block the leakage of laser to the outside of the main body 1 of the laser room, enabling the welding process to proceed continuously without stopping to replace parts, thereby greatly improving the production efficiency.

[0057] As Figures 1-3 shown, in some embodiments, each sealing mechanism 2 in the embodiments of the present application includes a sealing frame 21 and a plurality of sealing components 22. The plurality of sealing components 22 are sequentially arranged along the inner circumference of the sealing frame 21, and the outer peripheral side edges of the light blocking plate 41 can be respectively and sealingly engaged with the plurality of sealing components 22 of the same sealing mechanism 2.

[0058] By sequentially arranging a plurality of sealing components 22 along the inner circumference of the sealing frame 21, when the sliding table 4 drives the light blocking plate 41 past the sealing frame 21, the sealing components 22 can contact and engage with the light blocking plate 41, so that the light blocking plate 41 and the sealing components 22 jointly block the welding laser, ensuring that when the workpiece to be welded on the sliding table 4 is welded inside the main body 1 of the laser room, the welding laser will not leak to the outside of the main body 1 of the laser room. And during the process of replacing the workpiece to be welded, there is no need to open or close the door of the main body 1 of the laser room, thus enabling the welding process to proceed continuously and greatly improving the production efficiency.

[0059] Specifically, as Figure 1 、 Figure 3 and Figure 7 shown, in some embodiments, the sealing component 2 includes a mounting seat 221 and a blade 222. The mounting seat 221 is fixed to the sealing frame 21, the blade 222 is rotatably connected to the mounting seat 221, the rotation axis of the blade 222 is perpendicular to the first direction, and the side of the blade 222 close to the light blocking plate 41 is parallel to the rotation axis; when the sliding table 4 moves in the first direction towards the feeding direction, the side edges of the light blocking plate 41 can respectively contact the blades 222 of the respective sealing components 2 and push the blades 222 to rotate in the first clockwise direction.

[0060] The blade 222 is fixed to the sealing frame 21 through the mounting seat 221, so that the mounting seat 221 and the blade 222 form an integral body, which is more convenient for installing and repairing and replacing the combination of a single mounting seat 221 and the blade 222.

[0061] In addition, by setting the blade 222 and the mounting seat 221 to be rotatably connected, when the light shielding plate 41 passes through the sealing frame 21, during the process that the blade 222 contacts and engages with the light shielding plate 41, the blade 222 will not block the passage of the light shielding plate 41, thereby reducing the resistance generated by the blade 222 on the light shielding plate 41. However, during the passage of the light shielding plate 41, the blade 222 can engage with the light shielding plate 41 to jointly block the welding laser and prevent the welding laser from leaking outside the laser room main body 1.

[0062] In the embodiment of the present application, when the blade 222 is at the initial angle, the blade faces the light shielding plate, that is, the thickness direction of the blade is along the first direction.

[0063] In the embodiment of the present application, if the first clockwise direction is the clockwise direction, then the second clockwise direction is the counterclockwise direction.

[0064] As Figure 1 、 Figure 3 and Figure 7 shown, in some embodiments, the sealing assembly 22 further includes a first elastic member 223. The mounting seat 221 includes a first rotating groove 2211. The first elastic member 223 is disposed between the first rotating groove 2211 and the blade 222. The first elastic member 223 has a tendency to rotate the blade 222 in the second clockwise direction for resetting the blade 222, wherein the second clockwise direction is opposite to the first clockwise direction.

[0065] By arranging the first elastic member 223 between the first rotating groove 2211 of the mounting seat 221 and the blade 222, after the light shielding plate 41 passes by the blade 222, the blade 222 can rebound to the initial position under the elastic restoring force of the first elastic member 223, so that the blade 222 can continue to contact and engage with other subsequent light shielding plates 41 to jointly block the welding laser.

[0066] As Figure 1 、 Figure 3 and Figure 7 shown, in some embodiments, the sealing assembly 22 further includes a first limiting member 224. The first limiting member 224 is used to limit the rotation angle of the blade 222 to one side in the second clockwise direction.

[0067] By setting the first limiting member 224, it is possible to prevent the light shielding plate 41 from driving the blade 222 to rotate excessively to the side in the conveying direction after the light shielding plate 41 contacts the blade 222, resulting in a reduction in the sealing effect and causing laser leakage to the outside of the laser chamber main body 1. Moreover, it can also prevent interference with other blades 222.

[0068] Specifically, in some embodiments, the first limiting member 224 is fixedly arranged in the first rotation groove 2211, and the first limiting member 224 is arranged on the side of the blade 222 close to the discharge end of the conveying track 3.

[0069] As Figure 1 、 Figure 3 and Figure 8 shown, in some embodiments, the sealing assembly 22 further includes a second elastic member 225. The mounting seat 221 includes a second rotation groove 2212. The second elastic member 225 is arranged between the second rotation groove 2212 and the blade 222, and the second elastic member 225 has a tendency to make the blade 222 rotate in the first clockwise direction.

[0070] By setting the second elastic member 225, it can be ensured that during the process of the first elastic member 223 driving the blade 222 back to the initial position, the blade 222 will not rebound excessively under the action of the second elastic member 225, avoiding the blade 222 from tilting to the side away from the conveying direction under the elastic restoring force of the first elastic member 223 and causing interference with the subsequent light shielding plates 41 passing by.

[0071] As Figure 1 、 Figure 3 and Figure 8 shown, in some embodiments, the sealing assembly 22 further includes a second limiting member 226. The second limiting member 226 is used to limit the rotation angle of the blade 222 to the side in the first clockwise direction.

[0072] By setting the second limiting member 226, it is possible to prevent the blade 222 from rotating excessively to the side away from the conveying direction under the elastic restoring force of the first elastic member 223 after the light shielding plate 41 contacts the blade 222, resulting in interference with other blades 222 and causing the blade 222 to collide with other components and be damaged.

[0073] Specifically, in some embodiments, the second limiting member 226 is fixedly arranged in the second rotation groove 2212, and the second limiting member 226 is arranged on the side of the blade 222 away from the discharge end of the conveying track 3.

[0074] As Figures 1-3 shown, in some embodiments, the laser chamber further includes a welding mechanism 5. The welding mechanism 5 is used to weld the workpieces to be welded in the laser chamber main body 1. By setting the welding mechanism 5, the workpieces to be welded entering the laser chamber main body 1 can be welded.

[0075] Specifically, in some embodiments, the laser room further includes a welding mechanism 5. The welding mechanism 5 includes a robotic arm 51 and a laser welding head 52. One end of the robotic arm 51 is fixed inside the laser room main body 1, and the other end is fixedly provided with the laser welding head 52.

[0076] As Figure 3 and Figure 5 shown, in some embodiments, the shape of the light shielding plate 41 is the same as the shape of the inner circumference of the sealing frame 21.

[0077] By setting the shape of the light shielding plate 41 to be the same as the shape of the inner circumference of the sealing frame 21, the sealing effect between the light shielding plate 41 and the sealing mechanism 2 can be greatly improved, thereby avoiding the leakage of welding laser outside the laser room main body 1.

[0078] In addition, referring to Figure 6 shown, in some embodiments, since the robotic arm 51 and the laser welding head 52 are provided in the laser room, when the robotic arm 51 drives the laser welding head 52 to perform laser welding, due to a specific welding process trajectory, there is inevitably a situation of movement interference between the light shielding plate 41 and the laser welding head 52. Based on this, the shape of the light shielding plate 41 in the embodiments of the present application is trapezoidal.

[0079] Correspondingly, referring to Figure 4 shown, in some embodiments, in order to ensure the sealing effect between the sealing mechanism 2 and the light shielding plate 41, when the shape of the light shielding plate 41 is set to trapezoidal, the shape of the sealing frame 21 is also correspondingly improved and is also set to trapezoidal.

[0080] As Figure 1 and Figure 3 shown, in some embodiments, the sealing mechanism 2 further includes a support column 23, and the support column 23 is arranged at the bottom of the sealing frame 21.

[0081] By arranging the support column 23 at the bottom of the sealing frame 21, the entire sealing structure can be made more stable, thereby improving the sealing effect and avoiding laser leakage.

[0082] As Figure 2 shown, in some embodiments, the laser room is provided with a maintenance door 11.

[0083] By providing the maintenance door 11 on the laser room, when the components inside the laser room are damaged and cannot be used normally, the damaged components inside the laser room can be repaired by opening the maintenance door 11, thereby greatly improving the maintenance efficiency and avoiding the long-term shutdown of the laser room.

[0084] In a second aspect, an embodiment of the present application further provides a laser welding system, including the above-mentioned laser room.

[0085] In some embodiments, the laser welding system further includes a sling, which can hoist the sliding table 4 to the starting position of the conveying track 3 and unload the sliding table 4 at the end of the conveying track 3 onto the unloading platform, thus greatly improving the working efficiency of the laser welding system and significantly enhancing the degree of automation.

[0086] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0087] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
