Description

Technical Field

[0001] The utility model relates to the technical field of welding workstations, in particular to a workstation for continuous welding. Background Art

[0002] A robot welding workstation mainly consists of a welding robot and a turntable. The turntable is used to turn the workpiece to be welded to an ideal position and cooperate with the welding robot to complete welding.

[0003] Existing welding workstations often only target simple welding workpieces. When facing welding workpieces with more components and multiple welding processes, existing welding workstations often need to replace the tooling on the turntable after each welding process to perform the welding of the next process. The operation is troublesome, and the entire process requires a large amount of manpower and time.

[0020] Embodiment

[0021] Please refer to Figures 1 to 3 , a continuous welding workstation, including at least two welding units 10 arranged side by side. Each welding unit 10 includes a welding workshop 11, two welding robots 12, two positioners 13, two conveying mechanisms 14 and two material temporary storage racks 141; the welding robots 12, positioners 13 and conveying mechanisms 14 are all arranged in the welding workshop 11, and a material temporary storage rack 141 is arranged on both sides of each welding workshop 11 to form two rows of material temporary storage racks 141; the two welding robots 12 in each welding unit 10 are arranged side by side and the arrangement direction is parallel to the arrangement direction of the multiple welding units 10; the two positioners 13 are respectively located on both sides of the arrangement direction of the two welding robots 12; the head and tail ends of the two conveying mechanisms 14 are respectively close to the two positioners 13.

[0022] The overall structure of arranging the positioners 13 at the head and tail ends of the conveying mechanism 14 can effectively cooperate with the staff at both ends of the conveying mechanism 14 to quickly realize the rapid transfer of a large number of parts between the two positioners 13 and complete two welding processes; at the same time, further cooperate with the material temporary storage rack 141 outside the welding workshop 11 to temporarily store the semi-finished products welded by the welding workshop 11 for the staff of the next process to quickly take away and carry out welding processing in the next welding workshop 11. The whole workstation is reasonably designed and can effectively meet the continuous welding requirements of complex objects.

[0023] Please refer to Figure 2 In the embodiment, each of the transfer mechanisms 14 includes a conveyor belt 142 and two accessory temporary storage racks 15 respectively arranged at the head and tail ends of the conveyor belt 142. The accessory temporary storage rack 15 includes at least one storage layer. Preferably, the number of layers can be four to six. At the same time, each layer of the accessory temporary storage rack 15 is inclined towards the direction where the staff stands. The accessory temporary storage rack 15 is used to store the accessories required for the previous welding process and the next welding process. At the same time, the products completed in the previous welding process are conveyed to the end of the conveyor belt by the conveyor belt for the next welding process, so as to improve the overall welding efficiency

[0024] Please refer to Figure 1 In the embodiment, two movable wire spools 16 are further arranged between the two welding units 10. One movable wire spool 16 is arranged outside the first welding unit 10 and the last welding unit 10. The wire spool is connected to the welding wire feeder and is used to supply wire to the welding robot 12. One of the two movable wire spools 16 located between the two welding units 10 is used to supply wire to the welding robot 12 of the previous welding unit 10, and the other is used to supply wire to the welding robot 12 of the next welding unit 10. Through such a design, the space between the two welding units 10 can be fully utilized, ensuring the compact structure of the overall workstation and at the same time ensuring the wire supply to the welding robot 12

[0025] Please refer to Figure 2 and Figure 3 In the embodiment, a lift mechanism 17 is arranged on both sides in the arrangement direction of the two welding robots 12. The lift mechanism 17 includes a baffle 171, and the baffle 171 is located between the welding robot 12 and the positioner 13. The baffle 171 is used to block the arc light during welding and avoid direct harm to the eyes of the staff during welding

[0026] Furthermore, the lift mechanism 17 further includes a support frame 172, a cylinder 173 fixed on the support frame 172, a fixed block 174 fixed on the push rod of the cylinder 173, a guide rail 175 fixed on one side of the support frame 172, and a slider 176 fixed on the baffle 171. The fixed block 174 is fixedly connected to the baffle 171, and the slider 176 can slide on the guide rail 175 under the push of the cylinder 173

[0027] The overall structural design of the fixed block 174 cooperating with the guide rail 175 and the slider 176 can effectively realize the stable lifting control of a single baffle 171. When the welding robot 12 works on the positioner 13 on one side, the baffle 171 on the other side will rise to avoid the eyes of the staff on the other side being damaged by the arc light

[0028] Please refer toFigure 2 In the embodiment, the welding unit 10 further includes a support base 18. The lift mechanism 17, the welding robot 12, the conveyor belt, and the positioner 13 are all arranged on the support base 18. Two fixing grooves 181 for the front forks of the forklift to pass through are formed on the side of the support base 18. Through such an integrated base structure design, when the welding unit 10 needs to be moved, the forklift can effectively move the whole inside the welding workshop 11, greatly improving the convenience of installation and disassembly of the welding workshop 11, and effectively reducing the workload required for the layout of the welding workstation caused by the need to disassemble each part separately because they were previously set separately.

[0029] Please refer to Figure 1 The welding workshop 11 further includes a workshop main body 111 and a protective fence 112. The workshop main body 111 includes a number of core support columns for enclosing the welding position. The protective fence 112 is connected to the workshop main body 111 to form a protective enclosure on the workshop main body 111 to ensure the safety of the users and the overall strength of the welding workshop 11 at the same time.

[0030] Please refer to Figure 1 Above the workshop main body 111, a partition 113 and an installation fence 114 are further provided. The partition 113 can be used to place electronic instruments such as control boxes and display screens required by the control center in the upper space to reduce the overall floor area of the welding workstation. The installation fence 114 is used to ensure the safety of personnel.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
