[0035] See also Figure 1 and Figure 2 The reciprocating sliding part 54 includes a lead screw 3 541 which is rotatably installed on the two supporting legs on the same side of the support frame 2, and the left ends of the front and rear lead screws 3 541 are connected by a transmission belt 542. A No. 2 forward and reverse motor 543 is installed on the left side of the upper end of the upper support plate of the three-layer frame 1 through a motor seat, and the output shaft of the No. 2 forward and reverse motor 543 is fixedly connected to any one of the lead screws 3 541, and an annular slide 544 is fixedly sleeved on the upper side of the outer wall of the circular seat 52, and L-shaped sliding rods 545 are symmetrically installed on the outer wall of the annular slide 544.

[0036] When the uppermost annular welding bottom plate is located flush with the upper end surfaces of the left and right arc-shaped baffles 31, the first forward and reverse motor 623 controls the rotation of the rotating shaft 624, and the rotating shaft 624 is driven by the transmission gear 626 and the upper incomplete gear 622 to drive the upper waist-shaped baffle 61 to rotate around the support column 1 621 until the corresponding support column 2 631 slides from one end in the corresponding waist-shaped slide groove 630 to the other end. At this time, the upper waist-shaped baffle 61 is located at the upper side of the left and right arc-shaped baffles 31, and then the pneumatic push rod 629 is controlled to pass through the annular turntable 626. 28 drives the transmission gear 626 to move downward to the position meshing with the lower incomplete gear 622, and then controls the rotating shaft 624 to rotate in the opposite direction through the No. 1 forward and reverse motor 623. The rotating shaft 624 is transmitted through the transmission gear 626 and the upper incomplete gear 622, driving the upper waist-shaped baffle plate 61 to rotate in the opposite direction around the support column 1 621 until the corresponding support column 2 631 slides from one end in the corresponding waist-shaped slide groove 630 to the other end. At this time, the lower waist-shaped baffle plate 61 is located at the upper ends of the left and right arc-shaped baffle plates 31, and is movably fitted on the upper waist-shaped baffle plate 61.

[0037] The rotation of the connected lead screw 3 541 is then controlled by the No. 2 forward and reverse motor 543, and the lead screw 3 541 drives another lead screw 3 541 to rotate synchronously through the transmission belt 542. The front and rear lead screws 3 541 jointly drive the annular slide plate 544 to move leftward through the front and rear two L-shaped slide bars 545, and the annular slide plate 544 will drive the circular seat 52 to slide leftward along the waist-shaped through hole 51 to the upper position of the left and right arc-shaped baffles 31. It should be noted that during this period, the circular seat 52 slides along the upper waist-shaped baffle plate 61, and the multiple heating rings placed in the circular seat 52 will not fall off. The intermittent top feeding mechanism 3, the sliding feeding mechanism 5 and the auxiliary feeding mechanism 6 cooperate with the circular seat 52 to reciprocate left and right to feed the multiple heating rings intermittently to the upper position of the multiple annular welding base plates, thereby avoiding the problem of manually placing the annular welding base plate and multiple heating rings in sequence, and then performing soldering processing in sequence, which is time-consuming and labor-intensive, and effectively improves the soldering processing efficiency of the annular welding base plate and multiple heating rings.

[0038] See also Figure 1 and Figure 8 The intermittent pressing mechanism 4 includes a servo motor 2 41 installed on the upper end of the support plate of the support frame 2 corresponding to the servo motor 1 333 through a motor seat. The output shaft of the servo motor 2 41 rotates and passes through the support plate of the support frame 2, and is fixedly connected with a lead screw 2 42. The lead screw 2 42 is threadedly connected with a mounting disc 43. The lower end of the support plate of the support frame 2 is symmetrically installed with limit slide bars 44 on the left and right sides of the lead screw 2 42.

[0039] See also Figure 1 and Figure 8The intermittent pressing mechanism 4 also includes two pressing groups arranged at the lower end of the mounting disc 43 corresponding to the multiple sliding material through holes 53. The two pressing groups are symmetrically arranged. The pressing group includes multiple supporting slide bars 45 installed at the lower end of the mounting disc 43 corresponding to the multiple sliding material through holes 53. The multiple supporting slide bars 45 are evenly distributed in an eight-shaped shape. An arc-shaped pressing plate 46 is commonly installed at the lower ends of the two supporting slide bars 45 corresponding to the same sliding material through hole 53. The multiple arc-shaped pressing plates 46 are respectively movably fitted on the inner walls of the corresponding sliding material through holes 53.

[0040] When the circular seat 52 slides to the left along the waist-shaped through hole 51 to the upper side position of the left and right arc-shaped baffles 31, the servo motor 2 41 controls the lead screw 2 42 to drive the mounting disc 43 to move downward, and the mounting disc 43 drives the multiple arc-shaped pressure plates 46 to move downward through the multiple supporting slide rods 45, until the multiple arc-shaped pressure plates 46 push the multiple heating rings at the bottom to move downward and slide into the multiple sliding material through holes 53 on the upper waist-shaped baffle 61. At this time, the lower ends of the multiple heating rings at the bottom are movably attached to the lower waist-shaped baffle 61, and then the servo motor 2 41 controls the lead screw 2 42 The mounting disc 43 is driven to move upward, and the mounting disc 43 drives the multiple arc-shaped pressure plates 46 to move upward and return to their original positions through the multiple supporting slide bars 45. Then, the first forward and reverse motor 623 controls the rotation of the rotating shaft 624, and the rotating shaft 624 is driven by the transmission gear 626 and the upper incomplete gear 622, driving the upper waist-shaped baffle plate 61 to rotate around the support column 1 621 until the corresponding support column 2 631 slides from one end in the corresponding waist-shaped slide groove 630 to the other end to return to its original position. At this time, the lower waist-shaped baffle plate 61 returns to its original position, so that the multiple heating rings at the bottom are lost. Remove the lower waist-shaped baffle plate 61 from the cover, fall to the upper end of the annular welding bottom plate on the upper side, and then control the connected screw three 541 to rotate in the opposite direction through the No. 2 forward and reverse motor 543, and the screw three 541 drives another screw three 541 to rotate in the opposite direction synchronously through the transmission belt 542. The front and rear two screw threes 541 jointly drive the annular slide plate 544 to move to the right and return to the original position through the front and rear two L-shaped slide bars 545, and the annular slide plate 544 will drive the circular seat 52 to slide to the right along the waist-shaped through hole 51 to return to the original position, and then control the rotation shaft 624 to rotate in the opposite direction through the No. 1 forward and reverse motor 623. Rotate, the rotating shaft 624 is transmitted through the transmission gear 626 and the upper incomplete gear 622, driving the upper waist-shaped baffle plate 61 to rotate in the opposite direction around the support column 1 621, until the corresponding support column 2 631 slides from one end in the corresponding waist-shaped slide groove 630 to the other end position, at this time, the upper waist-shaped baffle plate 61 returns to its original position, and finally the servo motor 2 41 controls the lead screw 2 42 to drive the mounting disc 43 to move downward, and the mounting disc 43 drives the multiple arc-shaped pressure plates 46 to move downward through the multiple support slide rods 45, until the multiple arc-shaped pressure plates 46 respectively press the corresponding multiple heating rings.

[0041] After the multiple arc-shaped pressure plates 46 respectively press the corresponding multiple heating rings, the external multi-degree-of-freedom soldering manipulator performs soldering processing on the multiple welding points of the uppermost annular welding base plate and the multiple heating rings in sequence. When the soldering processing is completed, the servo motor 2 41 controls the lead screw 2 42 to drive the mounting disc 43 to move upward, and the mounting disc 43 drives the multiple arc-shaped pressure plates 46 to move upward and return to their original positions through the multiple supporting slide bars 45. Finally, the servo motor 1 333 controls the lead screw 1 332 to continue to rotate, and the lead screw 1 332 drives the left and right connecting rods 335 to move upward through the circular slide plate 334. The left and right connecting rods 335 jointly drive the annular top plate 336 to move upward along the front and rear arc-shaped limit plates 331. The annular top plate 336 will drive the multiple annular welding base plates to move upward until the second annular welding base plate on the upper side is located at a position flush with the upper end surfaces of the left and right arc-shaped baffles 31. At this time, the annular welding base plate on the upper side that has been soldered can be taken out manually.

[0042] By repeating the above operations, multiple annular welding base plates and multiple heating rings can be intermittently soldered. The intermittent pushing mechanism 3, the sliding feeding mechanism 5, the auxiliary feeding mechanism 6 and the intermittent pressing mechanism 4 cooperate with each other. By pre-placing multiple annular welding base plates and multiple heating rings and feeding the circular seat 52 back and forth, multiple heating rings can be intermittently pushed to the upper positions of multiple annular welding base plates, and multiple arc-shaped pressing plates 46 can respectively press the corresponding heating rings, so as to avoid the problem of easy displacement of the positions of multiple heating rings placed manually in sequence, and the time-consuming and labor-intensive subsequent soldering process. The loading and unloading of materials are convenient, and the soldering efficiency and quality of the annular welding base plate and multiple heating rings are effectively improved.
