Description

Technical Field

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

[0002] Circuit board soldering is the process of connecting electronic components to a circuit board using molten solder (usually a tin alloy). This process requires not only stable and reliable electrical connections, but also mechanical strength to withstand external forces such as vibration and impact in the operating environment.

[0003] In the prior art, patent publication number CN106914721A discloses a circuit board welding fixture, including a fixing frame, which is a square frame body. The fixing frame is provided with a plurality of sliding stops parallel to the short side of the fixing frame. One end of the sliding stop is connected to a fixing bracket that supports the circuit board, and the other end has a groove. The opening of the groove faces the outside of the sliding stop. The fixing bracket is connected to the inner sidewall of the short side of the fixing frame.

[0004] This type of multifunctional circuit board welding fixture has the following disadvantages: the circuit board is fixed by a fixed support and a support body for welding, but the height of the fixed support and the support body cannot be adjusted. Some electronic components have long leads, and if the leads touch the bottom of the fixed frame, the electronic components will be tilted, thus affecting the welding effect. Therefore, we propose a multifunctional circuit board welding fixture. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a multifunctional circuit board welding fixture. When clamping the circuit board, the clamping height can be adjusted according to the length of the electronic component pins to prevent the pins from contacting the bottom of the clamping seat, which would cause the electronic component to be skewed and thus affect the welding quality. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional circuit board welding fixture, including a welding stand, a gantry frame slidably connected to the upper end of the welding stand, a soldering iron slidably connected to the front side of the gantry frame, a control switch group provided at the front right end of the welding stand, and a clamping mechanism.

[0008] Wherein: the input end of the control switch group is electrically connected to an external power supply, and the input end of the soldering iron is electrically connected to the output end of the control switch group. When clamping the circuit board, the clamping height can be adjusted according to the length of the electronic component pins to prevent the pins from contacting the bottom of the clamping base, which would cause the electronic component to be skewed and thus affect the soldering quality.

[0009] Furthermore, the clamping mechanism also includes threaded rods, each of which is rotatably connected to the upper middle part of the sliding plate. Each threaded rod is threadedly connected to a threaded hole in the middle of a vertically adjacent clamping block. Each threaded rod has a knob at its upper end for adjusting the height of the clamping block.

The bidirectional lead screw extends to the outside of the clamping seat. A knob two is provided on the right side of the bidirectional lead screw to drive the two clamping blocks to slide towards each other.

[0011] Furthermore, the upper end of the welding seat is provided with symmetrically distributed sliding grooves, and each sliding groove is slidably connected to a slider. The gantry is set at the upper end between two sliders, driving the soldering iron to move longitudinally.

[0012] Furthermore, a lead screw 2 is rotatably connected between the front and rear side walls of the slide groove 1 on the left side. The lead screw 2 is threadedly connected to the threaded hole in the middle of the slider 1 on the left side. A motor 2 is provided at the rear left end of the welding seat.

[0013] Furthermore, a second sliding groove is provided on the front side of the gantry frame, and a second slider is slidably connected inside the second sliding groove. The soldering iron is located on the front side of the second slider, which drives the soldering iron to move laterally.

[0014] Furthermore, a lead screw is rotatably connected between the left and right side walls of the slide rail 2. The lead screw is threadedly connected to the threaded hole in the middle of the slider 2. A motor is installed on the left side of the gantry frame. The output shaft of the motor passes through the round hole 2 on the left side of the gantry frame and is fixedly connected to the left side of the lead screw. The input end of the motor is electrically connected to the output end of the control switch group to drive the slider 2 to move laterally.
