[0055] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0056] like Figure 1-10 As shown, the annular welding table includes a round seat 1; it also includes: an insulating tube 2, the insulating tube 2 is fixedly installed on the top surface of the round seat 1, and an electric furnace 201 is arranged in the insulating tube 2; a welding operation room, the number of the welding operation rooms is several, and the several welding operation rooms are distributed in a circular array around the insulating tube 2; a table plate 5, the number of the table plates 5 is several, and several of the table plates 5 are respectively fixedly installed in several of the welding operation rooms, and a carrier shell 6 with an opening on the top for holding welding tools is movably arranged above the top surface of the table plate 5; a flip door 202, the peripheral surface of the insulating tube 2 is provided with a plurality of through grooves distributed in a circular array and aligned with the carrier shell 6, and a plurality of through grooves are arranged in a circular array on the peripheral surface of the insulating tube 2. The through slots correspond to several welding operation rooms respectively, and flip doors 202 are rotatably installed in several of the through slots. A flip driving mechanism 9 for driving the flip door 202 to rotate to open or close the through slots is installed in the round seat 1; a conveying mechanism 7, the conveying mechanism 7 drives the carrier shell 6 to move, so that the carrier shell 6 is switched between two states of being located in the insulation tube 2 and being located in the welding operation room; when the carrier shell 6 is located in the insulation tube 2, the welding tools contained in the carrier shell 6 are heated by the electric furnace 201; the conveying mechanism 7 is also connected to the flip driving mechanism 9; a converging component 4, the converging component 4 is connected to the top of several of the welding operation rooms and the top of the insulation tube 2.

[0057] The heat-insulating cylinder 2 and the flip door 202 are both designed to be heat-insulating, and specifically can be made of a metal shell filled with heat-insulating materials such as asbestos rope.

[0058] Through the heat insulation design, the heat transfer from the electric furnace 201 to the welding operation room is reduced, thereby reducing the impact on the workshop temperature.

[0059] like Figure 1-2 As shown, as a specific technical solution, the focusing assembly 4 includes an electric furnace 201 gas collecting hood, a welding gas collecting hood 402, a connecting pipe 403 and a smoke exhaust pipe 404; the electric furnace 201 gas collecting hood is fixedly connected to the top of the insulation cylinder 2, and the number of the welding gas collecting hoods 402 is several, and several welding gas collecting hoods 402 are fixedly installed in a circular array around the electric furnace 201 gas collecting hood, and several welding gas collecting hoods 402 are respectively connected to the tops of several welding operation rooms, and the top of the welding gas collecting hood 402 is fixedly connected with a connecting pipe 403, and the end of the connecting pipe 403 away from the welding gas collecting hood 402 is fixedly connected to the electric furnace 201 gas collecting hood, and the smoke exhaust pipe 404 is fixedly connected to the top of the electric furnace 201 gas collecting hood.

[0060] During the specific implementation, an exhaust fan is arranged in the gas collecting hood of the electric furnace 201. Through the action of the exhaust fan, the smoke in the insulation tube 2 enters the gas collecting hood of the electric furnace 201. The smoke in the welding operation room passes through the welding gas collecting hood 402 and the connecting pipe 403, and then enters the gas collecting hood of the electric furnace 201, and then is discharged together through the exhaust pipe 404. The exhaust pipe 404 leads to the outdoor wax smoke filtration system for filtration treatment.

[0061] Among them, the welding gas collecting hood 402 and the electric furnace 201 gas collecting hood are both conical, which is convenient for collecting smoke during the processing.

[0062] Figure 1-2 In the figure, the welding operation room is a ring with 6 workstations, and the number of welding gas collecting hoods 402 is adapted to the number of welding operation rooms, which is also 6.

[0063] In specific implementation, when the module is relatively large or the factory does not need too many workstations, a ring design with 5 or less workstations can be used.

[0064] like Figure 1 As shown, as a specific technical solution, a plurality of partitions 3 are fixedly installed around the insulation tube 2, and the adjacent partitions 3 form a welding operation room, and the table plate 5 is fixedly connected to the plate surface of the partition 3; a wax stick fixing hole 501 is opened on the table plate 5, and a support column 502 is fixedly connected to the bottom of the table plate 5.

[0065] The two partitions 3 used to form the welding operation room are in an "eight" shape, and the partitions 3 are sufficient to separate the adjacent welding operation rooms, so that each workstation is independent of each other, avoiding mutual influence between them, and the operators do not disturb each other.

[0066] By setting the wax stick fixing hole 501, when the operator is performing welding operation, the wax stick fixing hole 501 can be used for inserting and fixing the wax stick of the module, which plays a role in facilitating welding.

[0067] like Figure 3-4 As shown in the figure, as a specific technical solution, the conveying mechanism 7 includes a guide frame 701, a fixed seat 702, a screw 703, an end frame 704, a driving assembly and a movable nut 709; the guide frame 701 is fixedly connected to the fixed seat 702, and the fixed seat 702 is fixedly connected to the bottom surface of the table 5, the screw 703 is rotatably installed in the guide frame 701, one end of the guide frame 701 is fixedly installed with an end frame 704, and the end frame 704 is installed with a driving assembly, The driving assembly is connected to the screw rod 703, the movable nut 709 is threadedly installed on the screw rod 703, and the movable nut 709 is slidably installed in the guide frame 701, an upper through groove 503 is opened on the plate surface of the table 5, a connecting arm 710 is fixedly connected to the top surface of the movable nut 709, the connecting arm 710 passes through the upper through groove 503, and the connecting arm 710 is fixedly connected to the carrier shell 6, and a first reinforcement plate 711 is fixedly installed between the connecting arm 710 and the carrier shell 6.

[0068] The driving assembly includes a motor 705, a first pulley 706, a second pulley 707 and a transmission belt 708; the motor 705 is fixedly mounted on the end frame 704, the first pulley 706 and the second pulley 707 are both rotatably mounted on the end frame 704, the second pulley 707 is fixedly connected to one end of the screw rod 703, the first pulley 706 is fixedly connected to the output shaft of the motor 705, and the transmission belt 708 is wound around the first pulley 706 and the second pulley 707.

[0069] When the temperature of the welding tool is not high enough, the welding tool needs to be placed in the electric furnace 201 for heating.

[0070] Specifically, the welding tool is placed in the carrier shell 6; the driving component drives the conveying mechanism 7, so that the conveying mechanism 7 passes the carrier shell 6 containing the welding tool through the through slot and enters the insulation cylinder 2, and is heated by the electric furnace 201; after heating, the driving component drives the conveying mechanism 7, so that the conveying mechanism 7 conveys the carrier shell 6 containing the welding tool into the welding operation room; the heating of the welding tool is completed.

[0071] The driving assembly drives the first pulley 706 to rotate through the motor 705, and the second pulley 707 is rotated through the transmission belt 708, so that the screw 703 rotates, and the screw 703 is rotated forward and reversed through the forward and reverse rotation of the motor 705.

[0072] When the screw rod 703 rotates forward, the movable nut 709 is driven. Under the guidance of the guide frame 701 , the movable nut 709 drives the carrier shell 6 to move through the connecting arm 710 , so that the carrier shell 6 enters the heat insulation tube 2 .

[0073] When the screw rod 703 is reversed, the movable nut 709 is driven to reset, and the carrier shell 6 is driven to reset through the connecting pen and enter the welding operation room.

[0074] The motor 705 is preferably a servo motor 705 .

[0075] like Figure 5-7 As shown, as a specific technical solution, the bottom surface of the movable nut 709 is fixedly connected with a bottom rod 712, and the bottom of the bottom rod 712 is provided with an elastic pressure rod 8, and the elastic pressure rod 8 includes a guide sleeve 801, a movable column 802, a first stopper 803, a spring and a push seat 805; a hole body is opened at the bottom end of the bottom rod 712, and a guide sleeve 801 is fixedly mounted on the hole body, and the movable column 802 is matched with the inner wall of the guide sleeve 801, and one end of the movable column 802 is fixedly connected with a push seat 805, and the spring is sleeved on the movable column 802, and the push seat 805 and the bottom rod 712 are elastically connected by a spring, and the end of the movable column 802 away from the push seat 805 is fixedly connected with the first stopper 803.

[0076] The flip driving mechanism 9 includes a first end seat 901, a connecting strip 902, a rack 903, a guide assembly, a rotating shaft 904 and a gear 905; the guide assembly is arranged inside the round seat 1, the guide assembly is connected to the rack 903, the rack 903 passes through a groove body provided on the side wall of the round seat 1, the rotating shaft 904 is rotatably installed in the side wall of the round seat 1, the part of the rotating shaft 904 located in the groove body is fixedly sleeved with a gear 905, the gear 905 is meshedly connected with the rack 903, the end of the rack 903 away from the guide assembly is fixedly connected to the connecting strip 902, the connecting strip 902 is fixedly connected to the first end seat 901, the first end seat 901 is fixedly connected to the push seat 805, and the rotating shaft 904 is fixedly connected to the flip door 202.

[0077] The guide assembly includes a guide bar 907, a fixed bar 908, a second reinforcement plate 909 and a second end seat 910; the guide bar 907 is fixedly connected to one end of the rack 903, the fixed bar 908 is fixedly installed in the round seat 1, a second reinforcement plate 909 is fixedly installed on one side of the fixed bar 908, a guide hole 9081 is opened on the fixed bar 908, the guide bar 907 is matched with the guide hole 9081, the end of the guide bar 907 away from the rack 903 is fixedly connected to the second end seat 910, and the connection between the guide bar 907 and the rack 903 is fixedly connected to the second stopper 906.

[0078] The flip driving mechanism 9 is used to drive the flip door 202 to open and close; at the same time, the flip driving mechanism 9 provides drive with the help of the conveying mechanism 7.

[0079] Specifically, Figure 6 As shown, there is a distance between the carrier shell 6 and the flip door 202. When the carrier shell 6 approaches the flip door 202 but does not enter the through slot, the flip drive mechanism 9 provides drive through the conveying mechanism 7 to open the flip door 202.

[0080] During the above process, the movable nut 709 drives the elastic pressure rod 8 and the first end seat 901, the connecting bar 902, the rack 903, and the guide bar 907 to move together through the bottom rod 712, and the rack 903 is meshed with the gear 905 for transmission, and the driving shaft 904 drives the flip door 202 to rotate until the second stop block 906 contacts the fixed bar 908 and is blocked, and the flip door 202 rotates 90° into the insulation tube 2 to open the through slot, and at the same time, there is still a distance of 1-2CM between the carrier shell 6 and the through slot.

[0082] During the resetting movement of the movable nut 709, the bottom rod 712 is reset together with the movable nut 709, and at the same time, the carrier shell 6 is driven to leave the insulation tube 2 and return to the welding operation room through the connecting arm 710. During the above process, the spring is reset. When the spring is in a compressed state, it always provides pressure for the push seat 805, so that the movable column 802, the push seat 805, the first end seat 901, the connecting bar 902, the rack 903, and the guide bar 907 do not move. After the carrier shell 6 returns to the welding operation room, the spring is reset, and the bottom rod 712 continues to move with the movable nut 709. The spring pulls the push seat 805 to reset and move, so that the rotating shaft 904 drives the flip door 202 to reset and flip, and the through slot is closed.

[0083] The left and right movement of the rack 903 is guided by the guide bar 907 and the guide hole 9081 .
