[0002] At present, in the electronic manufacturing industry, PCB boards (printed circuit boards) are indispensable components. The components installed on them are electrically connected through solder points. However, in the actual production and storage process, due to the influence of various factors such as environmental humidity, temperature, chemicals, etc., an oxide layer often forms on the surface of the solder points. This oxide layer not only causes the conductivity of the solder points to decrease, but may also affect the connection reliability between the components and the PCB board, thereby affecting the performance and stability of the entire electronic product.

[0003] The prior art has the following disadvantages:

[0004] 1. In traditional technology, clamping force is usually applied only on two opposite sides of the plate, while the other two sides of the plate are ignored.

[0005] 2. During the drilling or grinding process, the debris generated can easily scatter around the fixture or even fall into the gap between the fixture and the plate, which not only affects the cleanliness of the working environment, but may also cause the debris to clog the drill holes or scratch the surface of the plate, affecting product quality.

The output end of the hydraulic cylinder 18 is fixedly connected with a moving rod 19 by screws. One end of the moving rod 19 is fixedly connected to one side of one of the fixed blocks 3. The rotating shaft 24 is rotatably installed inside the layer plate 17. A waist-shaped plate 23 is fixedly sleeved on the rotating shaft 24. The bottom of the waist-shaped plate 23 is fixedly connected with two symmetrically arranged fixed columns 22 by screws. A guide rod 21 is fixedly sleeved on the fixed column 22. A cylinder 20 is movably hinged inside the guide rod 21. The tops of the two cylinders 20 are fixedly connected to the bottoms of the two bottom plates 2 respectively. One side of the two fixed blocks 3 is connected to a placement rack 13 by screws, and a non-slip pad 14 is bonded to the top of the placement rack 13. Through the arrangement of structures such as a hydraulic cylinder 18 and a positioning roller 7, when using the device, first place the plate on the top of the two placement racks 13, with the soldering point facing upward and the components facing downward, and then start the hydraulic cylinder 18. The hydraulic cylinder 18 simultaneously drives the positioning rollers 7 on the four fixed rods to clamp the plate, thereby ensuring the stability of the PCB board during the drilling process and avoiding drilling errors caused by the movement of the plate.

[0030] like Figure 4 As shown, the four fixed blocks are each provided with a rotating groove inside, and the rotating roller is rotatably installed inside the rotating groove.

[0031] like Figure 4 As shown, the top of the fixed block is fixedly connected to the vertical rod by screws, the bottom of one of the support rods is fixedly connected to the vertical rod by screws, and a spring is commonly connected between the vertical rod and the vertical rod.

At this time, the collection frame is already full of waste generated by drilling, which can be cleaned and processed, thereby improving practicality.

[0039] like Figure 1 As shown, a groove is provided inside the bracket, and the collecting frame is slidably connected inside the groove.
