[0026] Reference Figure 1 to Figure 2 The automatic welding protection device of the utility model is implemented as follows:
[0027] An automatic welding protection device comprises: a fixture table 100 and a protection net 200.
[0028] The fixture table 100 is fixedly connected to the protection net 200. The protection net 200 is erected in a vertical plane and perpendicular to the front-to-back direction. The protection net 200 has an operation window 210 that passes through the front and back directions.
[0029] The jig table 100 is arranged at the lower side of the operation window 210. The upper end of the jig table 100 has an operation table 110. The operation table 110 is flush with the lower end of the operation window 210. The operation table 110 is provided with a loading and unloading jig 120, and the loading and unloading jig 120 has a material positioning groove of a preset shape. The shape of the material positioning groove is set according to the shape of the tail pipe body and / or the welding bracket.
[0030] In actual use, the protective net 200 separates the operator and the welding robot on both sides, greatly improving safety. The operator can load and unload the material jig 120 in the operating window 210, and the tail pipe body or welding bracket can be placed in the material positioning groove for positioning. It can achieve human-machine isolation without hindering manual loading and unloading operations.
[0031] In this embodiment, the operation window 210 is rectangular. The width of the operation window 210 is consistent with the width of the operation table 110. The left and right ends of the operation window 210 are aligned with the left and right ends of the operation table 110.
[0032] To avoid scratches on the operator, protective edging is provided at both ends of the operating window 210. The protective edging extends up and down along the left and right edges of the operating window 210 and is connected to the protective net 200. In this embodiment, the protective edging is made of nitrile rubber. In other embodiments, the protective edging can also be made of other soft materials or other rubbers.
[0033] In this embodiment, the operating table 110 is arranged on the side of the protective net 200 facing the robot. The range outside the operating window 210 is isolated from the human and the machine by the protective net 200. In order to ensure that the operator completely leaves the range of the operating table 110 when the robot interacts with the loading and unloading fixture 120 on the operating table 110, the operating window 210 is provided with an openable and closable protective curtain mechanism 300. The protective curtain mechanism 300 includes: a partition curtain 310 and an opening and closing driving component 320. The opening and closing driving component 320 is used to drive the partition curtain 310 to open and close the operating window 210.
[0034] The upper edge of the operation window 210 has a top beam 220. The top beam 220 extends in the left-right direction.
[0035] In some embodiments, the upper end of the partition curtain 310 is slidably connected to the top beam 220, and the opening and closing driving member 320 is connected to the partition curtain 310 and moves it left and right relative to the protective net 200. When the operator completes the loading and unloading operation, the opening and closing driving member 320 drives the partition curtain 310 to move, shield the operating window 210, and separate the front and rear spaces of the operating window 210.
[0036] Since the width of the operating window 210 in the left-right direction is generally large, the opening and closing action of the partition curtain 310 moving left-right has a large displacement and takes a long time. In other embodiments, the partition curtain 310 can be slidably connected to the protection net 200 in the up-down direction, and the opening and closing driving member 320 is arranged in the up-down direction.
[0037] In this embodiment, the protective curtain mechanism 300 is arranged in pairs on the left and right sides of the operating window 210. When separation is required, the partition curtains 310 of the two protective curtain mechanisms 300 can move toward each other from the left and right ends of the operating window 210 to achieve shielding and separation of the operating window 210. Arranging the protective curtain mechanism 300 in pairs can greatly shorten the opening and closing stroke of the partition curtain 310.
[0038] In order to avoid obstructing the line of sight and hindering the observation of the operating table 110 and the robot area, the partition curtain 310 is made of transparent material. Furthermore, in order to avoid the partition curtain 310 occupying the space on the left and right sides of the operating window 210 when the protective curtain mechanism 300 is opened, the partition curtain 310 is preferably made of soft material. The partition curtain 310 made of soft material can be folded and stored when opened to avoid obstruction or blocking of the space on both sides of the operating window 210.
[0039] In this embodiment, the partition curtain 310 has both transparency and good flexibility. Specifically, the partition curtain 310 can be made of silicone rubber, PVC, PC or PS and other materials to form a film shape.
[0040] In this embodiment, the upper edge of the partition curtain 310 has a plurality of connecting parts arranged on the left and right sides. The two connecting parts provided at the left and right ends of the upper edge of the partition curtain 310 are a connecting end and a driving end respectively. The connecting end is fixedly connected to the top beam 220, the driving end is connected to the opening and closing driving member 320, and the remaining connecting parts are all slidably connected to the top beam 220.
[0041] The two protective curtain mechanisms 300 are arranged symmetrically with each other. In the protective curtain mechanism 300 arranged on the left side, the connection end and the driving end are respectively arranged at the left and right ends of the upper edge of the partition curtain 310. In the protective curtain mechanism 300 arranged on the right side, the driving end is arranged at the left end of the upper edge of the partition curtain 310, and the connection end is arranged at the right end of the upper edge of the partition curtain 310.
[0042] The connecting portion and the top beam 220 can be slidably connected in a variety of ways. In some embodiments, the top beam 220 has a guide rod extending left and right. The connecting portion is provided with a hook hooked on the guide rod. In some embodiments, the connecting portion is in the shape of a circular hole and is movably mounted on the outer side of the guide rod. In other embodiments, the top beam 220 has a slide rail extending left and right, the slide rail is provided with a plurality of sliders, and the connecting portion is detachably connected to the sliders.
[0043] In some embodiments, the opening and closing driving member 320 can be a linear driving member such as a cylinder, an electric push rod or a hydraulic push rod. The cylinder body of the opening and closing driving member 320 is fixedly connected to the protection net 200, and the output rod of the opening and closing driving member 320 is connected to the driving end of the partition curtain 310.
[0044] In this embodiment, the opening and closing driving member 320 includes: a driving wheel and a driving belt. The driving belt is wound around the driving wheel. The driving belt extends along a circular path, and at least one section of the driving belt extends left and right and is connected to the driving end of the partition curtain 310.
[0045] In order to realize the synchronous opening and closing of the two protective curtain mechanisms 300 arranged in pairs, the driving wheels of the two opening and closing driving components 320 are synchronously connected. Specifically, the two driving wheels are coaxially provided with mutually meshing transmission gears. One of the driving wheels is connected to the servo motor. During the opening and closing process, the servo motor can drive the two driving wheels to rotate synchronously, so that the two driving belts can move synchronously, drive the two partition curtains 310 to move closer to each other or away from each other, and realize the opening and closing of the operating window 210.
[0046] The operating table 110 is disposed on the side of the protective net 200 facing the robot. To facilitate the operator in preparing materials, the fixture table 100 further has a material preparation table 130 , and the material preparation table 130 is disposed on the other side of the protective net 200 .
[0047] In some embodiments, in order to make the opening and closing timing of the protective curtain mechanism 300 match the material picking and placing actions of the operator and the robot, oppositely arranged gratings are provided on the left and right sides of the operating window 210, and a proximity switch for sensing the partition curtain 310 is provided in the middle of the top beam 220.
[0048] In actual use, the opposing light barrier can detect whether the operator's hands have been completely pulled out of the operating window 210, and the proximity switch can detect whether the two partition curtains 310 are fully unfolded to the middle of the operating window 210. The robot will not intrude into the space of the operating table 110 until it is confirmed that there is no obstruction between the opposing light barriers and the two partition curtains 310 are unfolded to the middle of the operating window 210.
