Description

Technical Field

[0001] The utility model relates to the technical field of mainboard repair, in particular to a mainboard repair welding flipping device. Background Art

[0002] Motherboard repair welding is a process that uses soldering to remove the electronic components on the motherboard and replace and repair the damaged electronic components. However, the electronic components and solder points on the motherboard are located on the upper and lower sides of the motherboard respectively. During soldering, the motherboard needs to be constantly turned over.

[0003] The existing Chinese utility model patent with reference announcement number: CN216177393U discloses a motherboard repair welding flipping device for electronic products, including a base, a support frame fixedly connected to the middle position of both sides of the base, a rotating sleeve rotatably connected to the upper end of the support frame, a pair of clamps slidably connected in the rotating sleeve, a fixing groove is opened on the adjacent side of the clamps, a non-slip pad is fixedly connected in the fixing groove, and a fixing mechanism is arranged between the rotating sleeve and the support frame. The beneficial effect of the utility model is that the motherboard can be fixed in the rotating sleeve by rotating the bidirectional screw, and the rotating sleeve can be rotated to the specified position for fixing by inserting the rod of the fixing mechanism into the slot, so that the free flipping of the motherboard during welding can be realized, avoiding the troublesome operation of re-fixing the motherboard after flipping the motherboard.

[0004] The above-mentioned motherboard flipping device uses a screw rotation method to fix the motherboard in the rotating sleeve structure. Since both sides of the rotating sleeve structure are connected to the screws, the screws need to rotate synchronously to fix the motherboard. This method is very inconvenient. At the same time, the above-mentioned motherboard flipping device flips the motherboard manually. When flipping, the motherboard cannot be quickly in a horizontal position after flipping, and fine-tuning is required. Utility Model Content
