[0019] refer to Figure 1 , 2, 3, 4, 5, 6 and 7, detailed description of the embodiment of installing multiple crystal oscillators on the circuit board: a crystal oscillator welding tool, including a bottom plate 11 processed with a placement groove 12, the placement groove 12 is mainly used to place the circuit board, the placement groove 12 is rectangular. The four corners of the placement groove 12 are processed with convex arcs. The circuit board for soldering crystal oscillators can be effectively placed, while preventing the four right angles of the rectangle from interfering with the right angles of the circuit board. The setting of the convex arc can ensure the stable placement of the circuit board. The bottom plate 11 is detachably connected with a rotating shaft 13, which is threadedly connected to the rotating shaft 13, so that the rotating shaft 13 can be quickly disassembled and fixed. The rotating shaft 13 is rotatably connected with a cover plate 21, so that the cover plate 21 can be rotated. A plurality of welding holes 22 are processed on the cover plate 21, and the electronic components on the circuit board are heated by passing a welding gun through the plurality of welding holes 22, so as to perform welding. A placement hole 23 is processed in each welding hole 22 for placing a cylindrical crystal oscillator. The two pins of the crystal oscillator are placed in the corresponding welding holes 22, so as to facilitate subsequent welding by a welding gun. The plurality of welding holes 22 are all arranged at the upper part of the placement groove 12. Thus, the crystal oscillator can be placed on the upper part of the circuit board, and the position of the electronic component and the circuit board can be stably fixed, which is convenient for automatic welding of the crystal oscillator. A fixing groove 24 is symmetrically processed in each placement hole 23, and a plurality of the fixing grooves 24 are provided with fixing strips, which can be fixed by gluing. The fixing strip is made of plastic material, which can be a material with high plasticity such as rubber, and can clamp the crystal oscillator through the clamping force of deformation to fix the cylindrical crystal oscillator, so as to prevent rolling when the cover plate 21 rotates, which affects the welding of the crystal oscillator. Each placement hole 23 is processed with a material withdrawal groove 25, and a material withdrawal block 32 is slidably connected in each material withdrawal groove 25. The material withdrawal blocks 32 are fixedly connected to the pressing plate 31. Two guide rods 26 are fixedly connected to the cover plate 21. The pressing plate 31 is slidably connected to the two guide rods 26. A plurality of springs Ⅰ33 are fixedly connected between the pressing plate 31 and the cover plate 21. When welding is completed, it is necessary to separate the plurality of crystal oscillators from the corresponding placement holes 23. While slightly rotating the cover plate 21, the pressing plate 31 is pressed to compress the plurality of springs Ⅰ33 and drive the plurality of material withdrawal blocks 32 to move in the corresponding The material stripping block 32 pushes the welded crystal oscillator out of the placement hole 23, releases the pressed pressing plate 31, and multiple compressed springs Ⅰ33 reset and push the pressing plate 31 to reset, so as to facilitate the next crystal oscillator installation and welding. A dividing line wheel 42 is slidably connected in each welding hole 22, and the dividing line wheel 42 is fixedly connected to the slide 41. Two limit strips 27 for limiting the sliding of the slide 41 are symmetrically fixedly connected to the cover plate 21. When the installation of the crystal oscillator is completed, the slide 41 is pushed to slide, and the slide 41 drives multiple dividing line wheels 42 to slide.The wire dividing wheel 42 is a cam, and the multiple wire dividing wheels 42 correspond to the placement holes 23 one by one. The tip of the wire dividing wheel 42 corresponds to the pin of the crystal oscillator. When the wire dividing wheel 42 slides, it slides into the corresponding pin of the crystal oscillator to separate two close pins. It can simultaneously separate the pins of multiple crystal oscillators. When installing the crystal oscillator, you only need to pay attention to arranging the two pins of the same crystal oscillator horizontally side by side. This can ensure that when sliding multiple wire dividing wheels 42, the pins of multiple crystal oscillators are separated at the same time, thereby speeding up the welding speed.
[0020] refer to Figure 6 , an embodiment of pushing the slide 41 to slide and automatically reset is described in detail: two ear plates 28 are fixedly connected to the cover plate 21, and two connecting plates 43 are fixedly connected to the slide 41. The two connecting plates 43 are respectively connected to the corresponding ear plates 28 through springs II 44. A push block is fixedly connected to the end of the slide 41. When it is necessary to push the slide 41, the slide 41 is driven to slide by pushing the raised push block, so that the pins of multiple crystal oscillators are separated. When the slide 41 slides, the two connecting plates 43 are driven to slide. The two connecting plates 43 pull the spring II 44 to stretch. After the pins are separated, the push block is released, and the stretched spring II 44 is reset to drive the connecting plate 43 to reset. The connecting plate 43 drives the slide 41 to reset, and the slide 41 drives the multiple line dividing wheels 42 to reset. When preparing for the next crystal oscillator welding, the pins are separated to speed up the preparation speed of the crystal oscillator welding, thereby speeding up the welding speed of the crystal oscillator.
