Description

Technical Field

[0001] This utility model relates to the field of circuit board welding technology, specifically a PCB board welding fixture for component welding. Background Technology

[0002] PCB board soldering is a crucial step in electronics manufacturing. It involves fixing electronic components onto circuit boards through soldering to ensure circuit connectivity and electrical performance. However, conventional PCB board soldering is difficult to use simultaneously to solder different types and specifications of components onto the PCB board. This requires multiple changes of PCB soldering fixtures, resulting in low PCB board component soldering efficiency. Furthermore, traditional PCB board component soldering fixtures cannot adjust the PCB board for multi-angle soldering, affecting the soldering quality. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a PCB board welding fixture for component welding. To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0004] A PCB board welding fixture for component soldering, comprising:

[0005] A clamping assembly includes two sets of clamping rods, clamping plates, and a connecting block. The clamping plates are located at the bottom of the connecting block and extend out of the connecting block. A groove is provided on one side of the connecting block, and sliders are evenly spaced in the groove. First slide rails are provided on both sides of the sliders, and a second slide rail is provided on the top of the sliders. A pulley is provided at one end of the clamping rod, and the pulley rotates along the clamping rod. A top plate is provided on the top of the groove, and the distance between the top plate and the groove is equal to the diameter of the pulley. A third slide rail is provided at the bottom of the top plate. The two sets of pulleys drive the two sets of clamping rods to slide up and down on the first slide rails, and the pulleys move left and right on the second and third slide rails, thereby adjusting the distance between the two sets of clamping rods to accommodate PCBs of different sizes. This avoids the need to repeatedly change PCB fixtures, which would affect the soldering efficiency of the PCBs. The clamping rods and the clamping plates are used to clamp and fix the PCBs.

[0006] Preferably, the surface of the first slide rail is provided with first through holes at equal intervals, and the surface of the pulley is provided with second through holes at equal intervals. When the pulley rotates, the second through holes correspond one-to-one with the first through holes.

[0007] Preferably, the clamping rod is provided with a limiting rod on the side near the pulley, and a connecting rope is provided between the limiting rod and the clamping rod. The connecting rope is connected to the surface of the clamping rod, and the limiting rod is inserted into the first through hole and the second through hole to fix the pulley and the clamping rod to the surface of the first slide rail.

[0008] Preferably, a clamping plate is provided on the lower side of the clamping rod, and a compression spring is provided between the clamping rod and the clamping plate. When the clamping rod moves downward, it drives the clamping plate to move downward. The clamping plate and the clamping piece are used to clamp the PCB board.

[0009] Preferably, one end of the connecting block is provided with a flipping component, which includes a flipping motor and three sets of rotating shafts. Each set of rotating shafts has a clamping component on one side. The flipping motor drives the clamping component to rotate through the rotating shaft, thereby adjusting the rotation angle of the clamped PCB board. This ensures that technicians can solder the PCB board from multiple angles, guaranteeing the soldering quality of PCB board components and improving the work efficiency of PCB component soldering. Setting up three sets of clamping components in different positions enables the soldering of different components onto the PCB board through multiple operating interfaces. Each operating interface corresponds to the soldering of a set of components of the same type. Each technician only needs to be responsible for soldering a set of components of the same type, thereby improving the efficiency of PCB board component soldering and avoiding the impact of having to solder many types of components on the soldering efficiency and effect.

[0010] Preferably, one end of the flip motor is provided with a rotating component, which includes a rotating motor and a rotating rod. The rotating motor drives the flip motor to rotate through the rotating rod, thereby realizing the rotation of different clamping components and switching the operation interface.

[0011] Preferably, a fixing member is provided at one end of the rotary motor. The fixing member is a cube, and screw holes are provided at the four corners of the fixing member. The fixing member is fixed to the ground or suspended on other platforms through the screw holes.

[0012] Beneficial effects: This utility model discloses a PCB board welding fixture for component welding. The clamping assembly achieves the vertical translation and horizontal sliding of the two sets of clamping rods by sliding the pulleys between the first slide rail, the second slide rail, and the third slide rail. This enables the clamping rods to clamp PCB boards of different sizes. The clamping assembly is set as three sets of rotatable and flip-up operation interfaces. Each operation interface corresponds to the welding of a set of components of the same type. Each technician only needs to be responsible for welding a set of components of the same type, thereby improving the efficiency of PCB board component welding. Attached Figure Description

[0026] In an embodiment, such as Figure 3 As shown, the clamping rod 10 is provided with a limiting rod 17 on the side near the pulley 15. The limiting rod 17 is connected to the clamping rod 10 by a connecting rope 18.

Setting up three sets of clamping components 7 in different positions enables the soldering of different components onto the PCB board through multiple operating interfaces. Each operating interface corresponds to the soldering of a set of components of the same type. Each technician only needs to be responsible for soldering a set of components of the same type, thereby improving the efficiency of PCB board component soldering and avoiding the impact of having to solder many types of components on the soldering efficiency and effect.

[0029] In an embodiment, such as Figure 1 As shown, one end of the flip motor 5 is provided with a rotating component, which includes a rotating motor 3 and a rotating rod 4.

[0031] When in use, the clamping assembly 7 slides between the first slide rail 13, the second slide rail 20 and the third slide rail 19 via the pulley 15, thereby enabling the two sets of clamping rods 10 to move up and down and slide left and right, thus enabling the clamping rods 10 to clamp PCB boards of different sizes. The clamping assembly 7 is set as three sets of rotatable and flip-up operation interfaces, each operation interface corresponding to the soldering of a set of components of the same type, thereby improving the efficiency of PCB board component soldering.
