DETAILED DESCRIPTION

[0023] The present invention is further described in detail below. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.

[0024] like Figure 1-Figure 4 As shown, the technical solution of the present invention provides a continuous multi-unit independently controlled vacuum welding furnace, including a conveyor line 1, a plurality of welding furnace modules 2 arranged on both sides of the conveyor line 1, a connecting component 3 located between the conveyor line 1 and the welding furnace module 2, a transmission component 5 arranged opposite to the connecting component 3, and a clamping component 4 located on the connecting component 3.

[0025] The welding furnace module 2 is provided with an inlet and outlet 21, and the inlet and outlet 21 is provided with a plug valve, and the original parts enter or take out of the welding furnace module 2 through the inlet and outlet 21. Each of the welding furnace modules 2 operates independently, and the connection module corresponds to the welding furnace module 2 one by one, and the original parts are transmitted between the conveyor line 1 and the welding furnace module 2 through the connection assembly 3. The welding furnace module 2 includes a vacuum system, a reducing atmosphere system, a heating / cooling system, a gas flow control system, a safety system, a control system, etc., which can realize complete welding work. This scheme can realize the welding of multiple groups of original parts at the same time by setting up multiple independently operated welding furnace modules 2, and multiple groups of welding furnace modules 2 share a conveyor line 1, saving space and meeting the needs of large-scale production. The number of welding furnace modules 2 and the arrangement method can be set according to actual use requirements, and the use flexibility is high. And the above-mentioned setting method is convenient for later maintenance. When a single welding furnace module 2 needs maintenance, the equipment only needs to shield this vacuum cavity to continue to operate.

[0026] The two ends of the connection component 3 are respectively close to the conveyor line 1 and the inlet and outlet door, and the transmission component moves in the direction close to or away from the inlet and outlet 21. The clamping component 4 is slidably arranged above the connection component 3. The original is transported through the conveyor line 1. The conveyor line 1 is a plate-type conveyor line 1 with high stability, which meets the transportation requirements of smaller originals. When the original arrives at the corresponding welding furnace module 2, the gate valve opens the inlet and outlet door, and the transmission component 5 pushes the original to the corresponding welding furnace module 2 for welding. After the welding is completed, the driving module in the welding module pushes the original to the connection component 3, and then the clamping component 4 clamps the original after the welding is completed, and then the transmission component 5 drives the clamping component 4 to the conveyor line 1, and the holding component releases the clamping of the original, and the transmission component 5 drives the clamping component 4 to continue to move forward, so that the clamping component 4 has no obstruction to the original, and then the conveyor line 1 transports the original to the lower material end, and the transmission component 5 pushes the clamping component 4 to reset, so as to complete a welding process.

[0027] The connection assembly 3 includes a connection support 31 and a support plate 32 disposed on the connection support 31, and connection baffles 33 are disposed on both sides of the support plate 32. The top surface height of the support plate 32 is adapted to the top surface height of the conveyor line 1, and the connection support 31 is disposed on the conveyor line 1. The support seat acts as a bridge to ensure that the raw materials can smoothly enter and exit the welding furnace module 2. A glass plate 34 is embedded on the connection support plate 32 to reduce the friction between the original part and the support plate 32, so that the original part moves more smoothly.

[0028] The connecting baffle 33 is provided with a guide groove 35 adapted to the length of the connecting baffle 33 on the outside, and the clamping assembly 4 is slidably connected to the guide groove 35. The clamping assembly 4 includes a clamping frame 41, a clamping drive assembly provided on the clamping frame 41, and two clamping members provided on the clamping drive assembly and arranged opposite to each other. The two clamping members are initially away from each other to avoid blocking the entry and exit of the original. After the original is sent out of the welding furnace module 2, the clamping assembly 4 clamps the original.

[0029] The clamping drive assembly includes a driving motor 42 and a screw module 43 connected to the output end of the driving motor 42. The screw module 43 includes two parts arranged in opposite directions. The two clamping members are respectively located on the two parts of the screw module 43. The clamping drive assembly drives the two clamping members to move in a direction of approaching or moving away from each other. The clamping member includes a clamping connecting plate 44 and a clamping plate 45 fixed to the clamping connecting plate 44. The driving motor 42 drives the screw module 43 to rotate. Since the transmission directions of the two parts of the screw are opposite, the two clamping plates 45 can be ensured to move in opposite directions, thereby achieving the clamping or loosening of the original.

[0030] The conveying assembly 5 includes a conveying support 51, a conveying cylinder 52 arranged on the conveying support 51, and a conveying plate 53 connected to the output end of the conveying cylinder 52, and the bottom of the conveying plate 53 is higher than the top surface of the conveying line 1. When the conveying cylinder 52 delivers the original into the welding furnace module 2, it directly pushes the original into the welding furnace module 2, and when taking it out, it drives the clamping plate 45 to move and thus realizes the removal of the original. Electromagnets 54 are arranged on both sides of the conveying plate 53, and an iron plate is arranged on the clamping plate 45, and the iron plate and the electromagnet 54 are arranged oppositely. The electromagnet 54 on the transmission plate generates magnetism when energized, and can absorb the iron block 46 on the clamping plate 45, and transfer the original together with the clamping plate 45 to the conveying line 1, and then the power is turned off, the electromagnet 54 loses its magnetism, and the clamping plate 45 releases the clamping of the original. This scheme can realize the delivery and retrieval of the original through a group of transfer mechanisms, with a simple structure and small space occupation.

[0031] A limiting sleeve 55 is also provided on the transmission support 51, and a limiting rod 56 is connected to the transmission plate, and the limiting rod 56 is provided through the limiting sleeve 55. The limiting rod 56 cooperates with the limiting sleeve 55 to ensure the movement stability of the transmission plate.

[0032] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
