[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4 As shown, a copper-embedded PCB board that is easy to assemble includes a circuit board 1;

[0025] It also includes a plurality of positioning components 3 arranged on the outside of the circuit board 1, and the positioning components 3 are arranged in contact with the outer edge of the circuit board 1;

[0026] The positioning assembly 3 includes an elastic member 31, one end of which is connected to a positioning clamping plate 32. The elastic member 31 is in a U-shape, and the end thereof is inclined inwardly, and is connected to the positioning clamping plate 32 in an eight-shaped shape. A serrated protrusion is provided on the side of the positioning clamping plate 32 in contact with the circuit board 1. The material of the serrated protrusion is wear-resistant rubber. The elastic member 31 and the positioning clamping plate 32 together constitute an elastic structure that can be opened outward, and is used to form a preliminary clamping and fixing of the circuit board 1. Due to the ability to open outward, the positioning assembly 3 can clamp circuit boards 1 of different thicknesses. The serrated protrusion made of wear-resistant rubber material provided on the positioning clamping plate 32 can further increase the friction between the positioning clamping plate 32 and the circuit board 1, thereby ensuring that the device is After the clamping is formed, it is not easy to have point displacement. A fastening screw 33 is provided for rotation inside the elastic member 31. The top end of the fastening screw 33 passes through the top of the positioning clamp plate 32 and is connected to a turning handle. A compensation spring 34 is provided on the outside of the fastening screw 33. The bottom of the compensation spring 34 is connected to the bottom wall of the positioning clamp plate 32, and the top of the compensation spring 34 is connected to the top wall of the positioning clamp plate 32. The rotation of the fastening screw 33 can squeeze the elastic member 31, thereby reducing the spacing between the open ends of the elastic member 31, so that the positioning clamp plates 32 are close to each other, further improving the fixing effect of the positioning clamp plate 32. The elastic force generated at both ends of the compensation spring 34 acts on the elastic member 31, which can effectively offset the gap between the fastening screw 33 and the elastic member 31. The looseness caused by the existing thread gap ensures the stability of the elastic member 31 during the adjustment process. A transfer tube 35 is provided at the bottom of the elastic member 31, and a fixed suction cup 36 is connected to the bottom of the transfer tube 35. An airbag cover 37 is provided on the side of the elastic member 31 away from the positioning clamp 32. A metal sheet 38 is provided inside the airbag cover 37. The material of the airbag cover 37 is elastic rubber. The shape of the metal sheet 38 is arc-shaped, and its protruding end squeezes the side wall of the airbag cover 37 outward. The bottom of the airbag cover 37 is connected to an outlet pipe 39 that is in communication with the transfer tube 35. When assembling the circuit board 1, first fix the positioning component 3 at a predetermined point on the circuit board 1, and then press the airbag cover 37 to cause the airbag cover 37 to collapse. The arc of the metal sheet 38 The shaped protrusion is recessed to one side, so that the air inside the airbag cover 37 can be discharged from the fixed suction cup 36 through the air outlet pipe 39 and the transfer tube 35, and then the circuit board 1 is placed on the electronic component substrate. At this time, the fixed suction cup 36 can be adsorbed on the electronic component substrate, thereby forming a preliminary fixation for the circuit board 1, which is convenient for subsequent assembly operations. After the fixed suction cup 36 is adsorbed on the electronic component substrate, the staff lets go, and the airbag cover 37 has a tendency to recover its deformation under the elasticity of the metal sheet 38, thereby generating a large negative pressure environment inside the airbag cover 37, and the negative pressure environment acts on the fixed suction cup 36, which can further ensure the adsorption of the fixed suction cup 36 to the electronic component substrate, thereby further improving the fixing effect of the circuit board 1.

[0027] In this embodiment, specifically, fixing holes 2 are provided at both side edges of the circuit board 1, and the fixing holes 2 are used to install fixing screws, so as to facilitate fixing the circuit board 1 on the corresponding electronic components, thereby ensuring the overall stability of the device when in use.

[0028] Working principle of the utility model: when the device is in use, first fix the positioning component 3 on a predetermined point of the circuit board 1, rotate the fastening screw 33 to make the positioning clamp 32 further fix the circuit board 1, and then press the airbag cover 37 to make the airbag cover 37 and the metal sheet 38 recessed to one side, and then place the circuit board 1 on the electronic component substrate, and use the fixed suction cup 36 to adsorb the electronic component substrate to achieve preliminary fixation of the circuit board 1 on the electronic component substrate, which is convenient for subsequent assembly operations. After the fixed suction cup 36 is adsorbed on the electronic component substrate, the staff lets go, and the airbag cover 37 tends to recover its deformation under the action of the metal sheet 38, so that the fixed suction cup 36 generates a large negative pressure, which can further ensure the adsorption of the fixed suction cup 36 to the electronic component substrate, thereby improving the fixing effect of the circuit board 1.

[0029] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
