Description

Technical Field

[0001] This utility model relates to the field of soldering technology, and in particular to a positioning fixture for soldering circuit boards. Background Technology

[0002] The core function of circuit board soldering is to achieve a reliable connection between electronic components and the circuit board using low-melting-point solder, ensuring stable transmission of current and signals, while enhancing mechanical fixation to adapt to different operating conditions. Solder, after melting, forms a conductive path, tightly connecting electronic components (such as chips, resistors, and capacitors) to the circuit board pads, achieving stable transmission of current and signals. Solder has good conductivity, reducing resistance loss and ensuring normal circuit operation. However, circuit board soldering requires positioning fixtures to limit the solder. Traditional positioning fixtures mostly use cylinders to simply hold the circuit board against the solder during soldering. Because the positioning fixtures themselves lack a flipping structure, the circuit board needs to be removed and flipped, which is time-consuming and labor-intensive, thus reducing the effectiveness of use. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for circuit board soldering.

[0005] The top of the receiving seat is fixedly connected to two fixed support plates. Each of the two fixed support plates is rotatably connected to a fixed shaft on one of their symmetrical sides. A fixed frame is fixedly connected between the other ends of the two fixed shafts. One of the fixed shafts passes through the fixed support plate and is fixedly connected to a first synchronous wheel. A fixed component for adjusting the rotation of the first synchronous wheel is connected to the side wall of one of the fixed support plates. Two positioning components are provided between the two sides of the inner wall of the fixed frame.

[0006] As a further description of the above technical solution: the assembly component includes an assembly motor fixedly connected to the side wall of the assembly base, and the output end of the assembly motor is fixedly connected to an assembly bidirectional screw, so that the assembly motor drives the assembly bidirectional screw to rotate.

[0007] As a further description of the above technical solution: the end of the assembly bidirectional screw passes through the assembly seat and is rotatably connected to the inner wall of the assembly groove. Both assembly T-shaped plates are threadedly connected to the outer wall of the assembly bidirectional screw.

The second synchronous wheel meshes with the first synchronous wheel through a synchronous toothed belt, and drives the first synchronous wheel to rotate through the synchronous toothed belt on the second synchronous wheel.

[0010] As a further description of the above technical solution: the positioning component includes a positioning fixture frame fixedly connected between the two sides of the inner wall of the fixed frame. The outer wall of the positioning fixture frame is provided with a moving groove. Two symmetrical moving parts are movably sleeved on the outer wall of the positioning fixture frame. A moving abutment plate is fixedly connected to the side wall of the moving parts. A moving motor is fixedly connected to the side wall of the moving parts. A moving rod is fixedly connected to the output end of the moving motor. The moving motor drives the moving rod to rotate.

[0011] As a further description of the above technical solution: the end of the moving rod passes through the moving kit and extends into the moving groove. A moving wheel is fixedly connected to the end of the moving rod. Movable grooves are opened on opposite sides of the two moving abutment plates. Two symmetrical movable sliders are slidably connected inside the movable grooves. A movable abutment plate is fixedly connected to one end of the movable slider.

[0013] This utility model has the following beneficial effects:

[0014] 1. The fixed components enable the fixed motor to drive the fixed rod and the second synchronous pulley to rotate. The second synchronous pulley then drives the fixed shaft on the first synchronous pulley to rotate via a synchronous toothed belt. The fixed shaft also drives the material held against the two positioning components on the fixed frame to be adjusted and flipped as needed. The positioning components enable the movable motor to drive the movable wheels to rotate, with the two wheels rotating in opposite directions, bringing them closer together. The movable component on the movable motor then moves along the direction on the positioning fixture frame, moving the movable abutment plates and pressing them against the circuit board material. The movable components enable the movable motor to drive the movable bidirectional screw to rotate, bringing the two movable sliders closer together along the direction on the movable bidirectional screw. The movable sliders are slidably installed and guided inside the movable groove. The movable sliders also move the movable abutment plates, pressing them against the top and bottom sides of the circuit board material. This provides positioning and flipping processing functions, thereby improving the usability.

[0015] 2. The assembly components enable the assembly motor to drive the assembly double-sided screw to rotate. Then, the two assembly T-shaped plates move closer to each other along the direction on the assembly double-sided screw. At the same time, the assembly T-shaped plates slide and are guided inside the assembly slot. Then, the assembly T-shaped plates also drive the assembly shaft and assembly block on the assembly recess to move. At the same time, the assembly block also drives the scissor fork to move. Then, the scissor fork also drives the receiving shaft and receiving recess on the receiving sleeve block to move. Then, the receiving recess also drives the fixed frame on the receiving seat to move. Finally, the fixed frame drives the material pressed between the two positioning components to be adjusted to the appropriate height. Attached Figure Description

[0028] Working principle: When in use, the circuit board material to be processed is first placed inside the positioning fixture frame 31 on the positioning component. Then, the two moving motors 24 are started. The moving motors 24 drive the moving rod 25 and the moving wheel 26 to rotate. At the same time, the two moving wheels 26 rotate in opposite directions, so that the two moving wheels 26 move closer to each other. Then, the moving kit 22 on the moving motor 24 moves along the direction on the positioning fixture frame 31. The moving kit 22 also drives the moving abutment plate 23 to move, so that the two moving abutment plates 23 press against the circuit board material.

Then, the second synchronous wheel 20 drives the fixed shaft 14 on the first synchronous wheel 16 to rotate through the synchronous toothed belt 21. Then, the fixed shaft 14 also drives the material pressed against by the two positioning components on the fixed frame 15 to be adjusted and flipped as needed.

[0031] Simultaneously, the assembly motor 11 is started, which drives the assembly bidirectional screw 12 to rotate. Then, the two assembly T-shaped plates 3 move closer to each other along the direction on the assembly bidirectional screw 12. At the same time, the assembly T-shaped plates 3 are slidably installed and guided inside the assembly groove. Then, the assembly T-shaped plates 3 also drive the assembly recess 4 and the assembly rotating shaft 5 to move. Following this, the assembly rotating shaft 5 also drives the assembly block 6 to move.
