Technical Field

[0001] This utility model belongs to the technical field of PCB board assembly equipment, and in particular relates to an automatic positioning and welding device for PCB components. Background Technology

[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board. A complete PCB board has various electronic components mounted on its surface. In current technology, the soldering and positioning of electronic components rely on manual methods to find and fix the mounting positions. During the installation process, hand tremors often cause slight deviations between the installed position and the intended position, thus affecting the overall product quality of the PCB board. Furthermore, manual positioning and fixing consume a great deal of physical strength. In view of this, we propose an automatic positioning and soldering device for PCB components.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0020] An automatic positioning and soldering device for PCB components includes a soldering table 1. An L-shaped bracket 2 is fixedly connected to the top of the soldering table 1. A movable seat 3 is slidably connected to the top inner side of the L-shaped bracket 2. The upper part of the movable seat 3 slides along a T-shaped groove on the top inner side of the L-shaped bracket 2. A first screw 14 is rotatably connected to the inner side of the L-shaped bracket 2 via a bearing. The first screw 14 is threaded through the upper part of the movable seat 3, and one end of the first screw 14 is coaxially connected to the output end of a first motor 13 fixedly mounted on one side of the L-shaped bracket 2. A mounting base 4 is slidably connected to the bottom of the movable seat 3. The upper part of the mounting base 4 slides along the T-shaped groove on the bottom of the movable seat 3. A second screw 16 is rotatably connected to the inside of the movable seat 3 via a bearing. The second screw 16 is threaded through the mounting base 4. The upper part of the base 4, and the rear end of the second screw 16 are coaxially connected to the output end of the second motor 15 fixedly installed on the rear side of the movable base 3. An electric push rod 5 is fixedly installed on the mounting base 4. A suction cup 6 is fixedly connected to the lower end of the electric push rod 5. The suction cup 6 is connected to the air port of the air pump 8 fixedly installed on the side wall of the mounting base 4 through an air guide hose 7. A controller 12 is fixedly installed on the front side of the welding table 1. The controller 12 is electrically connected to an external power supply through a wire. The electric push rod 5, the air pump 8, the first motor 13 and the second motor 15 are electrically connected to the controller 12 through wires. A PCB board placement slot 9 is opened on the top of the welding table 1 below the suction cup 6. A PCB component positioning slot 11 is opened on the top of the welding table 1 on one side of the PCB board placement slot 9. The PCB component positioning slots 11 are arranged in a rectangular array. By placing the PCB board in the PCB board placement slot 9 and placing the PCB components to be soldered in the PCB component positioning slots 11, the first motor 13 and the second motor 15 are driven to rotate, which moves the suction cup 6. In conjunction with the air pump 8, the PCB components in the PCB component positioning slots 11 are adsorbed and moved to a designated position above the PCB board. This achieves automatic positioning for PCB component soldering, eliminating the need for manual positioning, making it more precise, efficient, and labor-saving. When soldering PCB components, the PCB board can be placed in the PCB board placement slot 9, and the PCB components to be soldered can be placed in the corresponding positions. In the PCB component positioning slot 11, the controller 12 drives the first motor 13 to rotate the first screw 14. The rotation of the first screw 14 causes the movable seat 3 to move left and right. The controller also drives the second motor 15 to rotate the second screw 16, which in turn causes the mounting seat 4 to move back and forth. This moves the electric push rod 5, along with the suction cup 6, above the PCB component to be picked up. The electric push rod 5 then causes the suction cup 6 to abut against the PCB component. Next, the air pump 8 and the air hose 7 create negative pressure inside the suction cup 6, which picks up the PCB component and moves it to the designated position above the PCB circuit board. Finally, the electric push rod 5 moves the suction cup 6 downward.By pressing the PCB components firmly onto the PCB circuit board, the positioned PCB components can be soldered and fixed. After the PCB components are soldered, air is introduced into the suction cup 6 through the cooperation of the air pump 8 and the air guide hose 7, which separates the suction cup 6 from the PCB components. By repeating the above operation, the automatic positioning and soldering of PCB components can be completed.

[0021] A PCB board positioning frame 10 is held in the PCB board placement slot 9. Magnetic suction pieces 101 are symmetrically embedded and fixed at the bottom of the PCB board positioning frame 10. A magnetic block that cooperates with the magnetic suction piece 101 is embedded and fixed at the bottom of the PCB board placement slot 9 below the magnetic suction piece 101. The PCB board positioning frame 10 is magnetically attracted and fixed in the PCB board placement slot 9 by the magnetic suction piece 101. The two sides inside the PCB board positioning frame 10 are symmetrically provided with snap-fit ​​slots 102. By setting the PCB board positioning frame 10 and replacing the PCB board positioning frame 10 with models with different inner frame sizes, it can be used to position PCB circuit boards of different specifications, making it more practical. When positioning PCB circuit boards, a PCB board positioning frame 10 that matches the specifications of the PCB circuit board can be selected and magnetically attracted and fixed in the PCB board placement slot 9 to meet the positioning needs of PCB circuit boards of different specifications.

[0022] Working Principle: During use, when soldering PCB components, the PCB board can be placed in the PCB board placement slot 9. When positioning the PCB circuit board, a PCB board positioning frame 10 that matches the specifications of the PCB circuit board can be selected and magnetically attached and fixed in the PCB board placement slot 9 to meet the positioning needs of PCB circuit boards of different specifications. The PCB components to be soldered are then placed in the corresponding PCB component positioning slots 11. At this time, the controller 12 drives the first motor 13 to rotate the first screw 14. The rotation of the first screw 14 can drive the moving base 3 to move left and right. The controller 15 drives the second screw 16 to rotate, which in turn drives the mounting base 4 to move back and forth. The system can move the electric push rod 5, along with the suction cup 6, above the PCB component to be picked up. The electric push rod 5 then moves the suction cup 6 to abut against the PCB component. Next, the air pump 8 and the air guide hose 7 create negative pressure inside the suction cup 6, which picks up the PCB component and moves it to a designated position above the PCB circuit board. Then, the electric push rod 5 moves the suction cup 6 downward, pressing the PCB component firmly onto the PCB circuit board, thus allowing the positioned PCB component to be soldered and fixed. After the PCB component is soldered, the air pump 8 and the air guide hose 7 work together to introduce gas into the suction cup 6, which separates the suction cup 6 from the PCB component. By repeating the above operation, the automatic positioning and soldering of the PCB component can be completed.
