In mass production, when multiple circuit boards need to be soldered at the same time, it is impossible to fix them at once, which wastes time and is not conducive to improving production efficiency. On the other hand, the adjustment function of traditional fixing fixtures is limited, making it difficult to accurately adapt to the fixing requirements of circuit boards of different sizes. Therefore, there is an urgent need for a controller circuit board soldering and fixing fixture to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Combination Figures 1 to 3 The controller circuit board welding and fixing fixture shown includes a base plate 1. Two clamping plates 2 of the same length are movably connected to both sides of the base plate 1. Each clamping plate 2 has a moving groove 3 penetrating its upper side. An adjusting device 4 is provided on the side of each moving groove 3 that is far apart from the others. Moving blocks 14 are movably connected to both ends of each moving groove 3. Circular grooves 15 penetrate the sides of each moving block 14. A limiting block 13 is provided at one end of each moving block 14. Movable plates 5 are provided at both ends of the clamping plates 2. Movable grooves 10 penetrate the upper side of each movable plate 5. Limiting posts 6 are provided at both ends of the base plate 1. Connecting plates 7 are provided at both ends of the limiting posts 6. A spring 9 is provided between two movable plates 5 located at the same end. A controller 8 is provided on the side of the base plate 1. An electric telescopic rod 11 is provided at the lower end of each movable plate 5 near the adjusting device 4. A fixing plate 12 is provided below each electric telescopic rod 11. The connection method between the controller and the electric telescopic rod in this utility model is existing technology and will not be described in detail.

[0023] The adjusting device 4 includes a threaded post 41, with fixed blocks 43 on both sides of the threaded post 41, and nuts 42 with matching threads movably connected to both ends of the threaded post 41.

[0024] The fixed block 43 is fixed at both ends of the movable groove 3, the length of the threaded post 41 is greater than the length of the movable groove 3, and the nuts 42 are movably connected to the movable block 14 on the side near the movable plate 5.

[0025] The threaded post 41 is movably connected inside the circular groove 15 and the two are of the same size. The circular groove 15 is located on the side of the movable groove 3 near the connecting plate 7.

[0026] The movable block 14 and the movable groove 3 are of the same size, and the limiting block 13 is located between the two clamping plates 2 and both are movably connected to the upper surface of the base plate 1.

[0027] The bottom of the movable plate 5 is flush with the bottom of the base plate 1 and the two are movably connected, while the fixed plate 12 is fixedly connected to the base plate 1.

[0028] The limiting post 6 is movably connected inside the movable groove 10 and the two are of the same size. The length of the limiting post 6 is the same as the width of the base plate 1. The limiting post 6 is movably connected inside the spring 9.

[0029] The movable groove 10 is located in the middle of the side of the spring 9, and the connecting plate 7 is fixedly connected to the base plate 1; the spring 9 can slow down the speed when the two clamping plates 2 approach each other, so as to prevent the circuit board from being damaged by excessive speed.

[0030] Working principle: In use, the circuit boards of the same size to be welded are first neatly arranged above the base plate 1. Then, the limiting block 13 on the side of the clamping plate is moved so that the limiting block is located at both ends of the circuit boards. Then, the nut 42 is rotated to engage with the threaded post 41, so that the nut 42 is fixed to the side of the moving block 14, thereby fixing the position of the limiting block 13. Then, the electric telescopic rod 11 is controlled by the controller 8 to move, so that the clamping plate 2 moves closer to both sides of the circuit board through the cooperation of the spring 9 and the movable plate 5, so that the clamping plate 2 can limit and fix both sides of the circuit board. Combined with the function of the limiting block 13, the position of the arranged circuit boards is fixed, which facilitates the subsequent neat and orderly welding work by the flexible welding device. This allows the fixing fixture to fix multiple circuit boards of the same size at one time.
