[0001] The utility model relates to the technical field of elevators, in particular to an elevator door panel production line. Background Art

[0002] As the main component of the elevator door system, the elevator door panel is mainly composed of the door panel body with left and right bending surfaces, the upper head, the lower head and the reinforcing ribs. In the production process of the elevator door panel, the production process of the elevator door panel has an important impact on the quality and service life of the elevator. Generally speaking, most factories choose aluminum alloy or stainless steel as the main material for production operations;

[0003] In the prior art, during the production process of elevator door panels, the upper head and the lower head need to be welded to the upper and lower ends of the door panel body respectively, and the reinforcing ribs are welded to the middle of the back of the door panel. The above welding process is mostly achieved by manual positioning or fixture positioning and pushing the door panel to move, which greatly reduces the production efficiency. At the same time, in the production welding process of the above door panels, there is an obvious defect in the door panels: after the reinforcing ribs are welded to the door panel body by butt welding or spot welding, there is a slight welding mark bulge on the front of the door panel, which is obviously found after the panel is refracted by the light source, seriously affecting the appearance. In places with high requirements for aesthetics, such door panels need to be covered with shielding stickers. Therefore, an elevator door panel production line is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide an elevator door panel production line to solve the problems of low production efficiency and weld convex spots after welding in the prior art of producing elevator door panels in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An elevator door panel production line comprises a plate feeder, a punching machine is adjacently arranged on one side of the plate feeder, and a transfer robot is rotatably installed on the right rear end of the punching machine, a transfer workbench is adjacently arranged in the horizontal direction on the side of the transfer robot away from the punching machine, a bending machine is arranged at the rear position between the transfer workbench and the transfer robot, a first laser welding machine, a second robot and a second laser welding machine are arranged in sequence from left to right on the right side of the rear end of the transfer workbench, a first robot and a third robot are arranged in sequence from left to right on the right side of the front end of the transfer workbench, a spot welding robot is adjacently arranged on the rear end of one side of the third robot, and a material receiving area is adjacently arranged on the other side of the spot welding robot.

[0007] Preferably, the transfer robot is arranged at a central position between the punching machine and the bending machine, and a sensor module is fixedly installed on the front end surface of the vertical end of the transfer robot.

[0008] Preferably, the welding ends of the first laser welding machine and the second laser welding machine are respectively arranged forward, and the first laser welding machine and the second laser welding machine are respectively rotatably connected to the supporting platform arranged at the rear position of the transfer workbench.

[0009] Preferably, the second manipulator is arranged on the center line between the first manipulator and the third manipulator, and the clamping end of the second manipulator is arranged opposite to the clamping end of the first manipulator and the third manipulator respectively.

[0010] Preferably, protective fences are respectively provided adjacent to the front of the punching machine and the transfer workbench, the protective fences are arranged in an upright structure, and the protective fences are provided with 5 panels in total.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, by adopting a plate feeder, a punching machine, a bending machine, a transfer workbench, a first manipulator, a second manipulator, a first laser welding machine, a third manipulator, a second laser welding machine, a spot welding manipulator and a material receiving area which are connected in sequence from the head end to the tail end, the plate is fed to punch, bend, weld, spot weld and receive.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-2 , the utility model provides a technical solution:

[0018] An elevator door panel production line includes a plate feeder 1, a punching machine 2 is adjacently arranged on one side of the plate feeder 1, and a transfer robot 3 is rotatably installed on the right rear end of the punching machine 2, a transfer workbench 5 is adjacently arranged in the horizontal direction on the side of the transfer robot 3 away from the punching machine 2, a bending machine 4 is arranged at the rear position between the transfer workbench 5 and the transfer robot 3, a first laser welding machine 6, a second robot 7 and a second laser welding machine 8 are arranged in sequence from left to right on the right side of the rear end of the transfer workbench 5, a first robot 12 and a third robot 9 are arranged in sequence from left to right on the right side of the front end of the transfer workbench 5, a spot welding robot 10 is adjacently arranged on the rear end of one side of the third robot 9, and a material receiving area 11 is adjacently arranged on the other side of the spot welding robot 10.

[0019] like Figure 1As shown, the transfer robot 3 is arranged in the center position between the punching machine 2 and the bending machine 4, and the front end surface of the vertical end of the transfer robot 3 is fixedly installed with a sensor module. Since the sensor module is installed at the front end of the transfer robot 3, and the entire production line recognizes that the material is brought out of the punching machine 2 through this sensor module, the transfer robot 3 will immediately complete the fixed action to send the material away after recognizing the material; the welding ends of the first laser welding machine 6 and the second laser welding machine 8 are respectively arranged forward, and the first laser welding machine 6 and the second laser welding machine 8 are respectively rotatably connected to the supporting support platform arranged at the rear position of the transfer workbench 5. As the entire production line cooperates with the second robot 7, the first robot 12 and the third robot 9 respectively, the lower head and the upper head are picked up on the transfer workbench 5 in turn, and the positioning arm of the reinforcement rib positioning device operated by the first laser welding machine 6 can conveniently fix the reinforcement rib on the panel body to avoid the displacement of the reinforcement rib during welding, and the laser welding machine can As the track moves back and forth, it is welded section by section according to the set welding position. The upper head and the lower head are treated in the same way. After being fixed in position by the fixed arm, they are welded by the first laser welding machine 6 and the second laser welding machine 8 respectively. The left and right sides of the welding machine are driven by the servo motor to move left and right for positioning, and the laser beam is transmitted through the reflector to ensure the accuracy of the welding point, without the error of manual positioning and the instability of manual welding, which is both beautiful and improves the quality; the second manipulator 7 is arranged on the center line between the first manipulator 12 and the third manipulator 9, and the clamping end of the second manipulator 7 is respectively arranged relative to the clamping end of the first manipulator 12 and the third manipulator 9. By respectively arranging the first manipulator 12, the second manipulator 7 and the third manipulator 9, when the production line is operating normally, the first manipulator 12 after starting can pick up the reinforcement rib and place it in the middle of the panel, the second manipulator 7 after starting will pick up the upper head and place it at the rear end of the panel, and the third manipulator 9 after starting will pick up the lower head and place it at the front end of the panel.

[0020] like Figure 1 and Figure 2 As shown, protective fences 13 are respectively provided adjacent to the front of the punching machine 2 and the transfer workbench 5. The protective fences 13 are arranged in an upright structure, and the protective fences 13 are provided with 5 panels in total. When the entire production line is carried out in an orderly manner, considering the light pollution factor, 5 protective fences 13 are provided on the periphery of the production line. In addition to the forklift entrance and exit being open, this fence structure can isolate the entry of external personnel, thereby improving the safety of the entire production line during operation.

[0021] Workflow: When the entire production line starts to run, the steel coil is hung on the plate feeder 1, and the front end of the steel plate enters the punching machine 2. The punching machine 2 cuts the panel of the required size on the plate and punches holes on the main body. The small waste that falls automatically enters the lower part of the discharge area. The panel body enters the front side placement platform of the punching machine 2. The transfer robot 3 automatically grabs the material and puts it on the operating platform of the bending machine 4 by identifying that there is material placed on the platform. The surface of the bending machine 4 is evenly divided into balls, and a brush is placed in the middle of the balls. When the panel moves, it can automatically clean dust and garbage. After the bending machine 4 folds the door panel, the panel is placed on the transfer workbench 5 through the transfer robot 3. The transfer workbench 5 is rotated by the roller and driven by the motor to drive the panel forward to the first operating platform. After the panel reaches the first operating platform, the panel is placed in the center through the push rod. At the same time, the conveyor belt is driven down by the cylinder to place the door panel on the surface of the first operating platform. The first robot 12 picks up the reinforcement rib and places it in the middle of the panel. The reinforcement rib is placed in the middle of the panel through the fixed arm. At this time, the first laser welding machine 6 welds the reinforcement rib with laser The second manipulator 7 picks up the upper head and places it at the rear end of the panel. The third manipulator 9 picks up the lower head and places it at the front end of the panel. The first laser welding machine 6 welds the upper head by moving on the track. The second laser welding machine 8 welds the lower head. The welding of all components and the panel is completed. The material is transferred to the working area of ​​the spot welding manipulator 10. This area is protected by a fence due to the strong light of spot welding. The spot welding manipulator 10 only spot welds the connection between the upper and lower heads and the reinforcement ribs. At the same time, it is driven by four revolutions, positioned in the middle through the door panel, and fixed front and back, so that the spot welding can be operated in a clear position. The operating platform is a roller conveyor. After welding is completed, it is conveyed to the transfer platform. If necessary, manual confirmation of whether the random inspection is qualified can be carried out. Above the receiving area 11 is a suction cup device, which can be freely raised and lowered and moved left and right. When the door panel cost is conveyed to the receiving area 11, the suction cup sucks on the door panel, and the roller continues to move forward until it is completely separated from the bottom of the door panel. At this time, the suction cup descends to place the door panel on the upper surface of the two crawlers under the conveyor belt. When the weighing sensor at the crawler receives a certain weight, the crawler starts to convey the door panel to the external forklift arm to send the door panel away, and the entire elevator door panel production operation can be completed.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
