Description

Technical Field

[0001] This utility model belongs to the field of welding equipment and relates to a special machine for automatic welding of straight seams of spliced ​​plates. Background Technology

[0002] Panel assembly refers to the joining of multiple sheet materials together. It addresses the difficulty of obtaining a single large sheet by combining several smaller sheets into a larger one. To weld the seams between two sheets, application CN201720178476.3 discloses a mobile automatic welding machine. Its disclosed technical solution includes a support frame, guide rails, and an automatic welding device, which welds straight seams by moving the automatic welding device itself.

[0003] The plates to be welded in the above technical solution need to be placed and aligned manually, but manual work is slow and affects the efficiency of welding work. Utility Model Content

[0004] This utility model addresses the above-mentioned problems by providing a special machine for automatic welding of straight seams in panel assembly.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic welding machine for straight seams of sheet metal, including an automatic welding device. The automatic welding device includes two longitudinal linear motor modules. A column is connected above the longitudinal linear motor modules. A crossbeam is connected to the top of the column. A transverse motor module is connected to the side of the crossbeam. A lifting welding head is connected to the transverse motor module. The machine also includes a first conveyor belt and a second conveyor belt respectively arranged on both longitudinal sides of the automatic welding device. A pushing mechanism and an alignment mechanism are arranged on both sides of the first and second conveyor belts. The pushing mechanism includes an electric push rod for pushing the sheet metal to move. The alignment mechanism includes several rollers for overlapping with the sheet metal. A first proximity switch is arranged at the end of the first conveyor belt near the second conveyor belt. A second proximity switch is arranged on the alignment mechanism. An automatic rebound linear displacement sensor for detecting the displacement of the sheet metal is arranged above the second conveyor belt.

[0006] Preferably, the pushing mechanism has two electric push rods arranged at intervals, and the end of the electric push rod near the conveyor belt is connected to a vertical plate.

[0007] Preferably, the automatic rebound linear displacement sensor is located on the side of the second conveyor belt near the pushing mechanism.

[0008] Preferably, a pressure plate mechanism is also provided above the conveyor belt. The pressure plate mechanism includes a ceiling bracket, a ceiling cylinder is provided on the ceiling bracket, and a pressure plate for pressing the plate is connected to the lower end of the ceiling cylinder.

[0009] Preferably, the automatic rebound linear displacement sensor includes a movable end, which is connected to a baffle for overlapping with the end face of the plate.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this invention, the first and second conveyor belts respectively transport the plates to a joint between them. A pushing mechanism and an alignment mechanism then align the plates, a pressure plate mechanism positions the two plates, and finally, an automatic welding device welds them together. This invention incorporates an automatic spring-loaded linear displacement sensor. When a plate on the second conveyor belt moves to the end, it pushes a baffle, allowing the sensor to detect the position of the plate's end face after movement—the position of the seam between the two plates. This facilitates the automatic welding device in identifying the welding point. Furthermore, after the pushing device pushes the plate, it disengages from the sensor, and the sensor returns to its original position. Attached Figure Description

Detailed Implementation

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, the automatic welding machine for straight seams of panels includes an automatic welding device 1. The automatic welding device 1 includes two longitudinal linear motor modules 11. The linear motor modules are used to drive the movement of components, which is existing technology and will not be described in detail here. A column 12 is connected above the longitudinal linear motor module 11. A crossbeam 13 is connected to the top of the column 12. A transverse motor module 14 is connected to the side of the crossbeam 13. A lifting welding head 15 is connected to the transverse motor module 14. The lifting welding head 15 is used to weld the plates, and it uses the linear motor module and other mechanisms to achieve lifting.

[0020] To achieve automatic alignment of the plates, this utility model also includes a first conveyor belt 2 and a second conveyor belt 3 respectively arranged on both longitudinal sides of the automatic welding device 1. The plates are picked up by a robotic arm or other equipment and placed on the two conveyor belts. A pushing mechanism 4 and an alignment mechanism 5 are arranged on both sides of the first conveyor belt 2 and the second conveyor belt 3. The pushing mechanism 4 includes an electric push rod 41 for pushing the plate to move. The alignment mechanism 5 includes several rollers for overlapping with the plate. Since the rollers on the sides of the two conveyor belts are all in a straight line, the electric push rod 41 pushes the plate onto the rollers to achieve positioning. A first proximity switch 21 is arranged at the end of the first conveyor belt 2 near the second conveyor belt 3. A second proximity switch 52 is arranged on the alignment mechanism 5. An automatic rebound linear displacement sensor 43 for detecting the displacement of the plate is arranged above the second conveyor belt 3.

[0021] Specifically, the alignment method of this utility model is as follows: 1. First, the first conveyor belt 2 conveys the first plate 6. After the first proximity switch 21 detects the plate, the first conveyor belt 2 stops conveying. 2. The electric push rod 41 on the side of the first conveyor belt 2 pushes the plate onto the roller. After the second proximity switch 52 detects the first plate 6, the electric push rod 41 stops moving. 3. After the above steps are completed, the second conveyor belt 3 starts to convey the second plate 7. The second plate 7 overlaps with the first plate 6, and under the drive of the second conveyor belt 3, the end face of the second plate 7 overlaps and aligns with the end face of the first plate 6. The second conveyor belt 3 stops, and the automatic rebound linear displacement sensor 43 detects the position of the end face of the second plate 7, that is, the position of the gap between the second plate 7 and the first plate 6. 4. The electric push rod 41 on the side of the second conveyor belt 3 pushes the second plate 7 onto the roller. After the second proximity switch 52 detects the second plate 7, the electric push rod 41 stops moving. After the second plate 7 moves, the automatic rebound linear displacement sensor 43 automatically rebounds. 5. The gap position is measured by the automatic rebound linear displacement sensor 43. The automatic welding device 1 adjusts the position of the lifting welding head 15 and then performs welding. 6. After welding, a panel is formed. The two electric push rods 41 release the panel. Since the rollers can rotate, the friction between them and the panel is small. Therefore, either conveyor belt transports the panel to the robotic arm for transfer.

[0022] Furthermore, the pushing mechanism 4 has two electric push rods 41 arranged at intervals to facilitate the flat pushing of the plate. The end of the electric push rod 41 near the conveyor belt is connected to a vertical plate 42, which is used to overlap with the plate.

[0023] Furthermore, an automatic rebound linear displacement sensor 43 is disposed on the side of the second conveyor belt 3 near the pushing mechanism 4.

[0024] Furthermore, a pressure plate mechanism 83 is also provided above the conveyor belt. The pressure plate mechanism 83 includes a ceiling bracket 81 for hanging on the roof or on a floor frame. A ceiling cylinder 82 is provided on the ceiling bracket 81. The lower end of the ceiling cylinder 82 is connected to a pressure plate 83 for pressing the plates. After step 4 above, two pressure plates 83 press the two plates respectively to prevent the two plates from shaking during welding in step 5.

[0025] Furthermore, the automatic rebound linear displacement sensor 43 includes a movable end, to which a baffle 44 is connected for overlapping with the end face of the plate, the baffle 44 extending downward from the movable end.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
