Technical Field

[0001] The utility model belongs to the technical field of welding, and in particular relates to a laser protection room and a welding station. Background Art

[0002] Laser welding is a welding method that uses a high-energy laser beam to instantaneously heat the workpiece surface, melting the workpiece surface material and solidifying it instantly, thereby achieving material connection. Laser welding offers advantages such as high welding speed, a small heat-affected zone, minimal deformation, and high weld quality. It is suitable for welding a variety of metals and non-metallic materials and is widely used in the automotive industry.

[0003] In the development of laser welding technology, in addition to improving welding efficiency, improving the safety of operators during the welding process is also a technical problem that needs to be solved urgently. Utility Model Content

[0004] In view of the above problems, the embodiments of the present application provide a laser protection room and a welding station, which can improve the safety of operators during the welding process.

[0005] In a first aspect, embodiments of the present application provide a laser shielding room for installation around laser welding equipment. The laser shielding room comprises a room body, a first shielding member, and a first driving member. The room body comprises a first protective wall, the first protective wall having an opening for allowing welded parts to enter and / or exit the room body. The first shielding member is disposed within the room body. A first driving member is connected to the first shielding member and is configured to drive the first shielding member to shield at least a portion of the opening during welding.

[0006] In the technical solution of the embodiment of the present application, the first driving member is configured to drive the first shielding member to block at least part of the opening during welding, so that the first shielding member can block part of the laser light, thereby reducing the laser light leaving the interior of the room from the opening, thereby reducing the risk of laser light injuring the operator, and thus improving the safety of the operator.

[0007] In some embodiments, the opening includes a second region and a first region arranged along the direction of gravity, wherein the first region is configured to allow a conveyor line of the laser welding equipment to pass through. The first driving member is configured to drive the first shielding member to partially shield the first region during welding. During welding, the orthographic projection of the first shielding member on the first protective wall does not overlap with the orthographic projection of the conveyor line on the first protective wall.

[0008] In the above solution, by configuring the first driver to drive the first shielding member to shield a portion of the first area during welding, the first shielding member can shield a portion of the laser light, thereby reducing the amount of laser light that leaves the interior of the room from the portion of the first area where the conveyor line is not located, thereby reducing the risk of laser light injuring the operator and improving operator safety. During welding, the orthographic projection of the first shielding member on the first protective wall and the orthographic projection of the conveyor line on the first protective wall do not overlap, thereby reducing the risk of the first shielding member interfering with the conveyor line when the first driver drives the first shielding member to shield a portion of the first area.

[0009] In some embodiments, there are two first protective walls arranged opposite to each other along the routing direction of the conveyor line, and there are two openings, which are respectively located in the two first protective walls.

[0010] In the above scheme, the first protective walls are two oppositely arranged along the routing direction of the conveyor line, and there are two openings, which are respectively located in the two first protective walls, so that the conveyor line can drive the welded parts into the room from one of the two openings and leave the room from the other, thereby not hindering the white body from passing through the welding station with the laser protection room, so that it can be transported normally in the line.

[0011] In some embodiments, the laser protection room further comprises a second shielding member and a second driving member. The second shielding member is disposed on the room body. The second driving member is connected to the second shielding member and is configured to drive the second shielding member to shield at least a portion of the second area during welding.

[0012] In the above solution, the second driving member is configured to drive the second shielding member to shield at least a portion of the second area during welding, so that the second shielding member can shield part of the laser light, thereby reducing the laser light leaving the interior of the room from the second area, thereby reducing the risk of laser light injuring the operator, and thus improving the safety of the operator.

[0013] In some embodiments, during welding, the orthographic projection of the first shielding member on the first protective wall and the orthographic projection of the conveying line on the first protective wall cover the second area.

[0014] In the above scheme, during welding, the orthographic projection of the first shielding member on the first protective wall and the orthographic projection of the conveying line on the first protective wall cover the second area, so that the first shielding member and the conveying line can block the laser light, thereby limiting the laser light from leaving the interior of the room from the first area, thereby reducing the risk of laser light injuring the operator.

[0015] In some embodiments, the first shielding member is provided with a avoidance portion for avoiding the conveyor line during welding.

[0016] In the above solution, the avoidance portion is provided on the first shielding member to reduce the risk of the first shielding member colliding with the conveyor line when the first driving member drives the first shielding member to move.

[0017] In some embodiments, there are two first driving members, each located on opposite sides of the first region in a first direction, with the first direction, the direction of the conveyor line, and the direction of gravity being perpendicular to each other. There are two first shielding members provided corresponding to the two first driving members, and the two first driving members are configured to respectively drive the two first shielding members to abut against each other along the first direction during welding, thereby enclosing at least a portion of the first region.

[0018] In the above solution, the two first driving members can simultaneously drive the first shielding member to move, so compared with a single first driving member driving a single first shielding member to move, the two first driving members respectively driving the two first shielding members to move can complete the shielding of the first area more quickly, thereby reducing the laser light leaving the interior of the room from the first area, thereby reducing the risk of laser light injuring the operator, and thus improving the safety of the operator.

[0019] In some embodiments, the first shielding member includes a first shielding portion and a second shielding portion. The first shielding portion is connected to the first driving member, and the second shielding portion is located on a side of the first shielding portion away from the first driving member in the first direction. The second shielding portion is made of a flexible material. During welding, the second shielding portions of the two first shielding members abut against each other.

[0020] In the above solution, the second shielding part is made of flexible material. During welding, the two second shielding parts abut against each other, and both second shielding parts undergo elastic deformation. On the one hand, the gap between the two second shielding parts can be filled, reducing the risk of laser light leaving the room body from between the two second shielding parts; on the other hand, the risk of damage to the first shielding part due to abutment and collision is reduced.

[0021] In some embodiments, the housing includes a housing and a guide member. The housing has a first protective wall, and the guide member is disposed on the first protective wall. A first shielding member is slidably disposed on the guide member, the guide member being configured to guide the first shielding member to move toward the opening in a second direction to shield at least a portion of the opening, wherein the second direction is parallel to the first protective wall.

[0022] In the above solution, the first shielding member is guided by the guide member to move toward the opening along the second direction, so as to improve the accuracy of the area of the opening shielded by the first shielding member during welding.

[0023] In a second aspect, an embodiment of the present application provides a welding station, comprising laser welding equipment and the laser protection room provided in the embodiment of the first aspect, wherein the laser protection room is installed outside the laser welding equipment.

[0034] Laser fusion welding is a welding method that uses a high-energy laser beam to instantaneously heat the workpiece surface, causing the surface material to melt and solidify instantly, thereby achieving a connection. During the laser welding process, the energy of the laser beam is converted into heat, raising the temperature of a localized area on the workpiece surface to a molten or semi-molten state. The laser beam then fuses two or more workpiece surface materials together under the action of the laser beam, forming a strong weld joint.

[0035] Laser welding has the advantages of fast welding speed, small heat-affected zone, small deformation, and high weld quality. It is suitable for welding various metal and non-metallic materials and is widely used in the automotive manufacturing field.

[0036] Laser radiation has a high energy density, and its thermal, photo-pressure, and photochemical effects can pose certain risks to human safety. Therefore, laser welding stations in welding workshops are all isolated in a laser shielding room, which has certain requirements for light tightness. Furthermore, the laser shielding room must have an opening for the welded parts to enter and exit the laser shielding room. Therefore, it is necessary to design a laser shielding room that can seal at least part of the opening during welding to reduce the risk of laser light to the operator.

[0037] In order to solve the above technical problems, refer to Figure 1-Figure 3 This embodiment provides a laser protection room 100 for being mounted outside a laser welding device. The laser protection room 100 includes a room body 10, a first shielding member 20, and a first driving member 30. The room body 10 includes a first protective wall 12, which is provided with an opening 11 for allowing welded parts to enter and / or exit the interior of the room body 10. The first shielding member 20 is provided on the room body 10. The first driving member 30 is connected to the first shielding member 20, and the first driving member 30 is configured to drive the first shielding member 20 to shield at least a portion of the opening 11 during welding.

[0038] The room body 10 is the part of the laser protection room 100 that is arranged outside the laser welding equipment. The room body 10 can be made of one or more of laser safety glass, laser safety film and metal plate.

[0039] The first protective wall 12 is a wall portion on either side of the room body 10 , and the opening 11 may be a channel-like structure for allowing welded parts to enter the room body 10 .

[0040] In some embodiments, the room 10 has two first protective walls 12 arranged opposite to each other. Both first protective walls 12 have an opening 11. The welded parts enter the room 10 from one of the two openings 11 and leave the room 10 from the other.

[0041] In other embodiments, the housing 10 has only one opening 11 , and the opening 11 is used for welded parts to enter and exit the interior of the housing 10 .

[0042] The first driving member 30 is a component that drives the first shielding member 20 to move. For example, the first driving member 30 can be, but is not limited to, a cylinder, a hydraulic cylinder, an electric telescopic rod, a linear module, etc.

[0043] The first shielding member 20 is a component in the laser protection room 100 used to shield at least a portion of the opening 11 during welding. For example, the first shielding member 20 can be a plate.

[0044] Specifically, during welding preparation, the first shielding member 20 does not block the opening 11, allowing the welded part to pass through the opening 11 and into the interior of the housing 10. During welding, the first driving member 30 drives the first shielding member 20 to block at least a portion of the opening 11, thereby blocking a portion of the laser beam, thereby reducing the amount of laser beam that leaves the interior of the housing 10 through the opening 11. After welding is completed, the first driving member 30 drives the first shielding member 20 to unblock the opening 11, allowing the welded part to pass through the opening 11 and out of the interior of the housing 10.

[0045] In the technical solution of the embodiment of the present application, the first driving member 30 is configured to drive the first shielding member 20 to shield at least part of the opening 11 during welding, so that the first shielding member 20 can shield part of the laser light, thereby reducing the laser light leaving the interior of the room body 10 from the opening 11, thereby reducing the risk of the laser light injuring the operator, and thus improving the safety of the operator.

[0046] According to some embodiments of the present application, opening 11 includes a second region 11B and a first region 11A arranged along the gravity direction Z. First region 11A is configured to allow a conveyor line of laser welding equipment to pass through. The first driver 30 is configured to drive the first shielding member 20 to partially shield first region 11A during welding. During welding, the orthographic projection of the first shielding member 20 on the first protective wall 12 does not overlap with the orthographic projection of the conveyor line on the first protective wall 12.

[0047] The first area 11A is a partial opening 11 through which a conveyor line of the laser welding equipment passes.

[0048] The conveyor line is a mechanism used to transport the workpiece in the laser welding equipment. The conveyor line can be, but is not limited to, a conveyor belt or a conveyor chain. For example, if the workpiece is a car body, the conveyor line can be a reciprocating rod.

[0049] It can be understood that in order to avoid the conveying line, there is a gap between the edge of the first area 11A and the conveying line.

[0050] The second area 11B is a partial opening 11 for allowing welded parts to enter the interior of the house body 10 .

[0051] The arrangement of the first area 11A and the second area 11B along the gravity direction Z can be understood as the first area 11A being located below the second area 11B, so that the conveyor line is located below the welded workpiece, thereby allowing the conveyor line to bear the gravity of the welded workpiece, so that the conveyor line can drive the welded workpiece to enter and leave the interior of the room 10 more smoothly.

[0052] "The first driving member 30 is configured to drive the first shielding member 20 to block part of the first area 11A during welding. During welding, the orthographic projection of the first shielding member 20 on the first protective wall 12 and the orthographic projection of the conveyor line on the first protective wall 12 do not overlap" can be understood as that during welding, the first driving member 30 drives the first shielding member 20 to block the gap between the edge of part of the first area 11A and the conveyor line.

[0053] In the above solution, by configuring the first driver 30 to drive the first shielding member 20 to block a portion of the first area 11A during welding, the first shielding member 20 can block a portion of the laser beam, thereby reducing the amount of laser beam that leaves the interior of the housing 10 from the portion of the first area 11A where the conveyor line is not located, thereby reducing the risk of laser beam injury to the operator and improving operator safety. During welding, the orthographic projection of the first shielding member 20 on the first protective wall 12 and the orthographic projection of the conveyor line on the first protective wall 12 do not overlap, thereby reducing the risk of the first shielding member 20 interfering with the conveyor line when the first driver 30 drives the first shielding member 20 to block a portion of the first area 11A.

[0054] According to some embodiments of the present application, there are two first protective walls 12 arranged opposite to each other along the routing direction of the conveyor line, and there are two openings 11, which are respectively located in the two first protective walls 12.

[0055] In the above solution, two first protective walls 12 are arranged opposite each other along the direction of the conveyor line, and there are two openings 11, one located in each of the two first protective walls 12. This facilitates the conveyor line to drive the welded workpiece into the room 10 through one of the two openings 11 and out of the room 10 through the other. This facilitates the connection of welding stations equipped with the laser protective room 100 with the production line.

[0056] According to some embodiments of the present application, the laser shielding room 100 further includes a second shielding member 40 and a second driving member. The second shielding member 40 is disposed on the room body 10. The second driving member is connected to the second shielding member 40 and is configured to drive the second shielding member 40 to shield at least a portion of the second area 11B during welding.

[0057] The second driving member is a component that drives the second shielding member 40 to move. For example, the second driving member can be, but is not limited to, a cylinder, a hydraulic cylinder, an electric telescopic rod, a linear module, etc.

[0058] The second shielding member 40 is a component used to shield at least the second area 11B during welding in the laser protection room 100. The second shielding member 40 can be made of one or more of laser safety glass, laser safety film, and metal plate.

[0059] In the embodiment where the opening 11 is a passage, the second shielding member 40 may be a sliding door for completely closing the second area 11B.

[0060] In the above solution, the second driving member is configured to drive the second shielding member 40 to shield at least a portion of the second area 11B during welding, so that the second shielding member 40 can shield part of the laser light, thereby reducing the laser light leaving the interior of the room 10 from the second area 11B, thereby reducing the risk of the laser light injuring the operator, thereby improving the safety of the operator.

[0061] According to some embodiments of the present application, during welding, the orthographic projection of the first shielding member 20 on the first protective wall 12 and the orthographic projection of the conveying line on the first protective wall 12 cover the second area 11B.

[0062] In the above scheme, during welding, the orthographic projection of the first shielding member 20 on the first protective wall 12 and the orthographic projection of the conveying line on the first protective wall 12 cover the second area 11B, so that the first shielding member 20 and the conveying line can block the laser light, thereby limiting the laser light from leaving the interior of the room 10 from the first area 11A, thereby reducing the risk of laser light injuring the operator.

[0063] According to some embodiments of the present application, the first shielding member 20 is provided with a avoiding portion 21 for avoiding the conveyor line during welding.

[0064] The avoidance portion 21 is a groove structure formed by a portion of the first shielding member 20 being recessed in a direction away from the conveying line.

[0065] In the above solution, the avoidance portion 21 is provided on the first shielding member 20 to reduce the risk of the first shielding member 20 colliding with the conveyor line when the first driving member 30 drives the first shielding member 20 to move.

[0066] According to some embodiments of the present application, there are two first driving members 30, each located on opposite sides of the first region 11A in the first direction X. The first direction X, the direction of the conveyor line, and the direction of gravity Z are perpendicular to each other. Two first shielding members 20 are provided corresponding to the two first driving members 30. The two first driving members 30 are configured to drive the two first shielding members 20 to abut against each other along the first direction X during welding, thereby enclosing at least a portion of the first region 11A.

[0067] Specifically, the two first driving members 30 can simultaneously drive the two first shielding members 20 toward or away from each other along the first direction X, thereby shielding or uncovering a portion of the first area 11A. Furthermore, compared to a single first driving member 30 driving a single first shielding member 20 along the first direction X, the two first driving members 30 drive the first shielding member 20 to shield or uncover a portion of the first area 11A in a shorter time and at a faster speed.

[0068] In the above solution, the two first driving members 30 can simultaneously drive the first shielding member 20 to move, so compared with a single first driving member 30 driving a single first shielding member 20 to move, the two first driving members 30 respectively driving the two first shielding members 20 to move can complete the shielding of the first area 11A more quickly, thereby reducing the laser light leaving the interior of the room 10 from the first area 11A, thereby reducing the risk of laser light injuring the operator, thereby improving the safety of the operator.

[0069] According to some embodiments of the present application, the first shielding member 20 includes a first shielding portion 20A and a second shielding portion 20B. The first shielding portion 20A is connected to the first driving member 30, and the second shielding portion 20B is located on a side of the first shielding portion 20A away from the first driving member 30 in the first direction X. The second shielding portion 20B is made of a flexible material. During welding, the second shielding portions 20B of the two first shielding members 20 abut against each other.

[0070] The first shielding portion 20A is a portion of the first shielding member 20 for connecting to the first driving member 30 .

[0071] The first shielding portion 20A can be made of one or more of laser safety glass, laser safety film, and metal sheet. It is understood that the first shielding portion 20A should have a certain strength to reduce the risk of deformation of the first shielding portion 20A when the first driving member 30 drives the first shielding portion 20A to move.

[0072] The second shielding portion 20B is a portion of the first shielding member 20 for contacting with another first shielding member 20 .

[0073] The second shielding portion 20B can be made of materials such as rubber and nylon.

[0074] In some embodiments, the second shielding portion 20B is a brush arranged on the side of the first shielding portion 20A away from the first driving member 30 in the first direction X. During welding, the two second shielding portions 20B are inserted into each other's gap along the first direction X to block the gap between the two first shielding portions 20A in the first direction X and act as a buffer between the two first shielding portions 20A.

[0075] In some embodiments, the second shielding portion 20B is a rubber block arranged on the side of the first shielding portion 20A away from the first driving member 30 in the first direction X. During welding, the two second shielding portions 20B abut against each other along the first direction X to elastically deform to block the gap between the two first shielding portions 20A in the first direction X and act as a buffer between the two first shielding portions 20A.

[0076] In the above solution, the second shielding portion 20B is made of a flexible material. During welding, the two second shielding portions 20B abut against each other, and both second shielding portions 20B undergo elastic deformation. On the one hand, the gap between the two second shielding portions 20B can be filled, reducing the risk of the laser light leaving the room body 10 from between the two second shielding portions 20B; on the other hand, the risk of damage to the first shielding member 20 due to abutment and collision is reduced.

[0077] According to some embodiments of the present application, a housing 10 includes a housing 10A and a guide member 10B. The housing 10A has a first protective wall 12, and the guide member 10B is disposed on the first protective wall 12. A first shielding member 20 is slidably disposed on the guide member 10B. The guide member 10B is configured to guide the first shielding member 20 to move toward the opening 11 along a second direction parallel to the first protective wall 12, thereby shielding at least a portion of the opening 11.

[0078] The housing 10A is a component in the housing 10 for accommodating the laser welding equipment.

[0079] The guide member 10B is a component for guiding the first shielding member 20 to move along the second direction. Exemplarily, the guide member 10B can be a slide groove, a guide rod or a guide rail.

[0080] The second direction is any direction parallel to the first protective wall 12. For example, the second direction can be parallel to the gravity direction Z, or the second direction can be parallel to the first direction X, or the second direction can be any direction that forms an angle with both the first direction X and the gravity direction Z.

[0081] In some embodiments, the guide member 10B is a guide rail, which is two guide rails arranged parallel to the first protective wall 12. The two guide members 10B extend along the second direction, and the first shielding member 20 is slidably installed on the guide member 10B through a slider matching the guide member 10B.

[0082] In the above solution, the first shielding member 20 is guided by the guide member 10B to move toward the opening 11 along the second direction, so as to improve the accuracy of the area of the opening 11 shielded by the first shielding member 20 during welding.

[0083] According to some embodiments of the present application, an embodiment of the present application provides a welding station, including laser welding equipment and the laser protection room 100 provided in the first embodiment, and the laser protection room 100 is installed outside the laser welding equipment.

[0084] According to some embodiments of the present application, a laser protection room 100 is provided, referring to Figure 1-Figure 3 The laser protection room 100 includes a room body 10 , a first shielding member 20 and a first driving member 30 .

[0085] The room body 10 includes two first protective walls 12, which are arranged opposite to each other along the routing direction of the conveyor line. There are two openings 11, which are respectively located in the two first protective walls 12. One of the two openings 11 is used to allow the welded parts to enter the interior of the room body 10, and the other is used to allow the welded parts to leave the interior of the room body 10.

[0086] The housing 10 includes a housing 10A and a guide member 10B. The housing 10A has a first protective wall 12, and the guide member 10B is disposed on the first protective wall 12. A first shielding member 20 is slidably disposed on the guide member 10B. The guide member 10B is configured to guide the first shielding member 20 in a first direction X toward the opening 11, thereby shielding at least a portion of the opening 11. The first direction X, the conveyor line's routing direction, and the direction of gravity Z are all perpendicular to each other.

[0087] The opening 11 includes a second area 11B and a first area 11A arranged along the gravity direction Z. The first area 11A is used for the conveyor line of the laser welding equipment to pass through. The first driving member 30 is configured to drive the first shielding member 20 to shield a portion of the first area 11A during welding.

[0088] During welding, the orthographic projection of the first shielding member 20 on the first protective wall 12 and the orthographic projection of the conveyor line on the first protective wall 12 do not overlap, and the orthographic projection of the first shielding member 20 on the first protective wall 12 and the orthographic projection of the conveyor line on the first protective wall 12 cover the second area 11B. This allows the first shielding member 20 and the conveyor line to block the laser beam, thereby limiting the laser beam from leaving the interior of the room 10 through the first area 11A, thereby reducing the risk of laser beam harming the operator.

[0089] There are two first driving members 30, which are respectively located on opposite sides of the first area 11A in the first direction X. There are two first shielding members 20 corresponding to the two first driving members 30. The two first driving members 30 are configured to drive the two first shielding members 20 to abut along the first direction X during welding to close at least part of the first area 11A.

[0090] The first shielding member 20 includes a first shielding portion 20A and a second shielding portion 20B. The first shielding portion 20A is connected to the first driving member 30, and the second shielding portion 20B is located on the side of the first shielding portion 20A away from the first driving member 30 in the first direction X. The second shielding portion 20B is made of a flexible material. During welding, the second shielding portions 20B of the two first shielding members 20 abut against each other. Filling the gap between the two second shielding portions 20B reduces the risk of laser light escaping the housing 10 through the gap between the two second shielding portions 20B. Furthermore, it reduces the risk of damage to the first shielding member 20 due to abutment or collision.

[0091] The second area 11B is used to allow welded parts to enter the interior of the room 10. The laser protection room 100 also includes a second shielding member 40 and a second driver. The second shielding member 40 is disposed within the room 10. The second driver is connected to the second shielding member 40 and is configured to drive the second shielding member 40 to shield the second area 11B during welding. This allows the second shielding member 40 to block the laser beam, thereby limiting the laser beam from exiting the room 10 through the second area 11B. This reduces the risk of laser beam injury to the operator and improves operator safety.
