DETAILED DESCRIPTION
[0018] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0019] like Figures 1 to 2 As shown, a circuit board soldering auxiliary table includes a soldering table 1. A clamping mechanism for fixing the circuit board is installed on the soldering table 1. The clamping mechanism includes a mounting frame 2. The front end of the mounting frame 2 is provided with an opening. The two sides inside are symmetrically provided with clamping frames 3. The clamping frames 3 have a U-shaped structure, and the length of the front end is less than the length of the rear end. Multiple telescopic rods 4 are installed between the clamping frames 3 and the inner wall of the mounting frame 2. A compression spring 5 is sleeved on the outside of the telescopic rods 4. The inner side of the clamping frames 3 is provided with a slot adapted to the thickness of the circuit board. Handles are fixed to both the upper and lower sides.
[0020] By pushing the clamping frame 3, it compresses the telescopic rod 4 and the compression spring 5, increasing the distance between the two clamping frames 3. This facilitates the placement of the circuit board between the two clamping frames 3, ensuring it is flush with the slot. Removing the pushing force on the clamping frames 3 allows them to move closer together under the action of the compression spring 5, thus clamping and securing the circuit board. The front end of the clamping frame 3 is shorter than its rear end, allowing the rear end of the circuit board to be inserted into the slot at the rear end of the clamping frame 3, facilitating its installation and fixation.
[0021] like Figure 2 and Figure 3 As shown, a central column 6 is connected to the rear end of the mounting frame 2. A rotary cylinder 7 for driving the central column 6 to rotate is installed on the upper part of the rear end of the welding table 1. Two sliding grooves are symmetrically opened at the rear end of the mounting frame 2, and a protective cover 8 is fixedly connected to the outer side of the rear end of the mounting frame 2 and sleeved on the outer side of the sliding groove. A connecting block 9 penetrating the sliding groove is fixedly connected to the rear end of the two clamping frames 3. The two connecting blocks 9 have different lengths and fixed strips 10 are fixedly connected to the ends of the two connecting blocks 9. A rack 11 is installed on the opposite side of the two fixed strips 10. A fixed shaft 12 is fixedly connected between the two racks 11 on the inner side of the protective cover 8. A gear 13 that meshes with the two racks 11 is rotatably installed on the fixed shaft 12. A top cover 14 is detachably installed on the top of the protective cover 8. The central column 6 is fixedly installed at the rear end of the protective cover 8.
[0022] When one clamping frame 3 moves, it drives fixed strip 10 and rack 11 to move through connecting block 9, and another rack 11 and fixed strip 10 move synchronously under the action of gear 13, so that the two clamping frames 3 move synchronously close to or away from each other.
[0023] As shown in Figure 2 and Figure 4 , an auxiliary positioning mechanism is further arranged between the rear end of the welding table 1 and the mounting frame 2, the auxiliary positioning mechanism comprising support frames 15 arranged on both sides of the welding table 1 and a cylinder 16 arranged at the rear end of the mounting frame 2, a limiting cylinder 17 is arranged at the upper front end of the support frame 15, and an electromagnet 18 is arranged at the rear end of the support frame 15, a armature 19 is arranged at the rear end surface of the cylinder 16, a tension spring 20 is connected between the armature 19 and the inner bottom surface of the cylinder 16, and round limiting blocks are arranged at both ends of the armature 19, the diameter of the limiting blocks is matched with the inner diameter of the limiting cylinder 17.
[0024] When the mounting frame 2 is in a horizontal state, the magnetic force generated by the energized electromagnet 18 attracts the armature 19, so that one end of the armature 19 is inserted into the limiting cylinder 17, and the tension spring 20 is stretched under stress, thereby effectively reducing the rotation of the mounting frame 2 and improving the stability of the mounting frame 2; when the circuit board needs to be flipped, the electromagnet 18 is de-energized, the tension of the tension spring 20 disappears and the tension spring 20 is retracted, so that the armature 19 is separated from the limiting cylinder 17, and at this time the rotary cylinder 7 can be started to flip the mounting frame 2.
[0025] In specific use, the clamping frame 3 is pushed by the handle, so that the two clamping frames 3 are separated from each other, the circuit board is placed between the two clamping frames 3, and then the pushing force on the clamping frame 3 is removed, so that the two clamping frames 3 are close to each other under the action of the compression spring 5, so that the clamping and fixing of the circuit board can be realized; when one side of the circuit board is welded, the electromagnet 18 is de-energized to separate the armature 19 from the limiting cylinder 17, and at this time the rotary cylinder 7 can be started to flip the mounting frame 2 and the circuit board. The circuit board does not need to be re-clamped during the welding process, and the welding efficiency is improved.
[0026] The un-disclosed parts in the utility model are all prior art, and the specific structure and working principle will not be described again.
