[0002] Circuit boards are core components in modern electronic products. They can connect the various electronic components on the circuit board through the copper foil set inside, so as to realize different functions according to the design requirements of the circuit board. When producing circuit boards, operators often need to solder electronic components to the circuit board through equipment or manually to ensure smooth conduction between the components.

[0003] When soldering the conductive sheet on the circuit board, due to the large overall area of ​​the metal conductive sheet, the soldering process is prone to uneven distribution of solder or weak connection at some locations, resulting in cold solder joints. The common cold solder joint detection method is manual or using tweezers to shake. When the conductive sheet is close to the circuit board, it is not convenient for the tweezers to reach into the gap between the two. The conductive sheet that is close to the circuit board is not convenient for the operator to manually pull the conductive sheet. There are certain inconveniences in the operation process, and there is also a situation where the judgment is not accurate. . Utility Model Content

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] See also Figure 1-5 A circuit board conductive component welding inspection device includes a conductive plate movable component 1 with an overall strip-shaped structure, and a holding component 2 that enables the conductive plate movable component 1 to be held in the hand of a user.

[0034] Specifically, the conductive plate movable assembly 1 includes a fixed portion 11 and a movable portion 12 arranged on the fixed portion 11. The fixed portion 11 is generally in a strip-shaped structure, and the movable portion 12 can form a protrusion on the surface of the fixed portion 11 in a direction perpendicular to the fixed portion 11 as a whole. In order to facilitate the conductive plate movable assembly 1 to pull the conductive part, the surface of the conductive part of the circuit board to be inspected after welding is provided with an opening for the end of the fixed portion 11 connected to the movable part 122 to pass through. When it is necessary to inspect the welding strength of the conductive part welded on the circuit board, the user can extend the movable portion 12 into the opening on the conductive part through the fixed portion 11. After the movable portion 12 forms a protrusion that can hook and pull the conductive part, the user can lift the fixed portion 11, thereby realizing the detection of whether the conductive part is poorly soldered.

[0035] The holding component 2 includes a soft holding piece 21 arranged at one end of the fixed part 11 away from the movable part 12, and a driving component 22 arranged on the soft holding piece 21, wherein the soft holding piece 21 can be common soft rubber, and the soft holding piece 21 and the driving component 22 form an annular structure allowing the user's hand to penetrate at one end of the fixed part 11, which can be put on the user's hand, and the driving component 22 can drive the movable part 12 to form a protrusion on the surface of the fixed part 11, and the driving component 22 can be an electric or pneumatic driving device. When the soft holding piece 21 is held by the user, the conductive plate movable component 1 is located as a whole at the palm of the user.

[0036] In some embodiments, the movable portion 12 includes at least one sealing rubber cover 121 disposed on the surface of the fixed portion 11, and an active chamber isolated from the outside is formed between the sealing rubber cover 121 and the fixed portion 11. The driving component 22 includes an elastic airbag 221 disposed on the soft holding piece 21, and an air supply hose 222 connecting the elastic airbag 221 and the active chamber. In addition, an air supply channel connecting the air supply hose 222 and the active chamber is provided on the surface of the fixed portion 11. When the soft holding piece 21 is put on the hand, the user can pinch the elastic airbag 221 to send the air in the elastic airbag 221 into the interior of the active chamber, thereby causing the sealing rubber cover 121 to expand as a whole to form a bulge, which is convenient for the user to pull up the conductive parts soldered on the circuit board.

[0037] Taking into account that the sealing rubber cover 121 is relatively soft after overall expansion, the movable part 12 includes at least one movable part 122 arranged on the surface of the fixed part 11, and the movable part 122 is located inside the movable chamber, and the movable part 122 is connected to the inside of the sealing rubber cover 121. The movable part 122 is generally in a strip-shaped structure, and one end of the movable part 122 is movably connected to the surface of the fixed part 11 through a hinge. The movable part 122 can expand together with the sealing rubber cover 121, thereby achieving a more secure hook and pull on the conductive plate. In order to prevent the movable part 122 from protruding from the outside of the fixed part 11 as a whole and making it inconvenient for the user to hold it, a groove is provided on the surface of the fixed part 11 for the movable part 122 and the sealing rubber cover 121 to be received.
