[0019] This utility model provides the following technical solution: Example 1 Combination Figures 1 to 5A circuit board stabilizing welding device with vibration elimination structure includes a base plate 1, a base 2, a conveyor belt 3, a workbench 4 and a placement plate 5. An adjustment mechanism 7 is provided on the base plate 1 and the placement plate 5. A guide plate 8 is fixedly connected to the left side of the base 2 and the top of the base plate 1.

A pushing mechanism 6 is provided on the workbench 4 and the placement plate 5. The adjustment mechanism 7 includes a moving component 71 and a buffer component 72, with the buffer component 72 located on the left side of the moving component 71; The movable component 71 includes a relay 713 and a rectangular slot 715. The rectangular slot 715 is opened inside the placement plate 5. The inner wall of the rectangular slot 715 has a first sliding groove 718 on the left and right sides. The front and rear sides of the first sliding groove 718 are slidably connected to the sliding plate 717 respectively. The two sliding plates 717 are fixedly connected to the placement plate 5. The top left and right sides of the placement plate 5 are fixedly connected to the limit blocks 711.

[0020] Furthermore, the electric push rod 719 drives the fixing plate 714, and the fixing plate 714 drives the mounting plate 716. When the two placement seats 712 move to opposite sides, the soldered circuit board can fall onto the conveyor belt 3 for conveying. After being guided by the guide plate 8, it is placed on the base plate 1. The first spring 722 is compressed, and at the same time, the fixing rod 721 can also drive the mounting block 727, and the second spring 724 can be stretched. Then, with the cooperation of the first spring 722 and the second spring 724, the circuit board can be buffered and protected from falling and accumulating on the base plate 1.

[0021] Example 2 See Figure 1-6 Furthermore, based on Embodiment 1, the pushing mechanism 6 includes a limiting seat 601, which is fixedly connected to the left and right sides of the top of the workbench 4. A long rod 68 is fixedly connected between the two limiting seats 601. A support plate 66 is fixedly connected to the right side of the top of the workbench 4. A threaded hole 62 is opened inside the support plate 66. Connecting rods 63 are fixedly connected to both ends of the right side of the support plate 66. A moving plate 65 is slidably connected to the surfaces of the two connecting rods 63. A motor 64 is fixedly connected to the right side of the moving plate 65. A motor 64 is fixedly connected to the left side of the motor 64. There is a threaded rod 67, and a connecting plate 61 is rotatably connected to the left side of the threaded rod 67. The left side of the connecting plate 61 is fixedly connected to the placement plate 5. The surface of the threaded rod 67 is threadedly connected to the inside of the threaded hole 62. Connecting blocks 602 are fixedly connected to the front and rear sides of the top of the placement plate 5 respectively. Slide seats 69 are fixedly connected to the outside of the two connecting blocks 602. The relay 713 is fixedly connected to the top of the connecting blocks 602. There are two slide seats 69 and two long rods 68. The two long rods 68 are set on the front and rear sides of the placement plate 5. The inside of the slide seat 69 and the surface of the long rod 68 are slidably connected.

[0022] Furthermore, when the threaded rod 67 and the threaded hole 62 are connected by threads, the threaded rod 67 will move. The threaded rod 67 drives the connecting plate 61, and the connecting plate 61 drives the placement plate 5 to move, so that the placement plate 5 can be moved and set on the top of the long square groove 9, which facilitates the transportation of the welded circuit boards and facilitates their unified collection later.

[0023] In actual operation, when this device is used to solder the circuit board, the circuit board can be placed on top of the two placement seats 712, and then soldered by hand with a soldering gun. After soldering, the threaded rod 67 can be rotated by the motor 64. When the threaded rod 67 and the threaded hole 62 are connected by threads, the threaded rod 67 will move. The threaded rod 67 drives the connecting plate 61, and the connecting plate 61 drives the placement plate 5 to move. At the same time, the moving plate 65 can also slide on the surface of the connecting rod 63, and the slide 69 slides on the surface of the long rod 68, so that the placement plate 5 can be moved and set on the top of the long square groove 9, which is convenient for the later transportation of the soldered circuit board and convenient for the later unified collection. Relay 713 drives the contacts to operate via an electromagnetic coil. Utilizing the parallel or series characteristics of the normally open contact NO, it achieves synchronous control of the power circuits of the two electric actuators 719. When the coil is energized, the contacts close, and the two electric actuators 719 start simultaneously. When the electric actuators 719 start, they drive the fixing plate 714, which in turn drives the mounting plate 716. The mounting plate 716 then moves the placement seat 712 within the rectangular groove 715. Simultaneously, the sliding plate 717 slides within the first sliding groove 718. When the two placement seats 712 move to opposite sides, the soldered circuit board can be dropped onto the conveyor belt 3 for transport, and then guided by the guide plate 8 onto the base plate 1. When the baffle 7201 is pushed by the circuit board, the first spring 722 is compressed, and at the same time the fixing rod 721 can also drive the mounting block 727. Since the mounting block 727, the hinge plate 726 and the moving seat 725 are hinged together, the second spring 724 can be stretched. Then, with the cooperation of the first spring 722 and the second spring 724, the circuit board can be buffered from falling and accumulating on the base plate 1, thus protecting the circuit board.
