Description

Technical Field

[0001] This utility model relates to the technical field of PCB circuit board processing tools, and in particular to a PCB circuit board welding device. Background Technology

[0002] With the rapid development of the electronic information industry, PCB circuit boards, as the core carrier of electronic devices, are constantly expanding their application scenarios, from consumer electronics to industrial control, from automotive electronics to aerospace, which puts forward increasingly stringent requirements for the welding precision, production efficiency and reliability of PCB circuit boards. Traditional PCB soldering equipment has significant shortcomings in its flipping structure design: most adopt belt drive, friction wheel drive, or snap-on flipping structure. These structures generally suffer from unstable power transmission and slippage. Belts tend to loosen after long-term use, and friction wheels are affected by oil and wear, leading to a decrease in friction. Snap-on structures, due to their fixed angle, are prone to loosening. All of these can cause deviations in the flipping angle and displacement of the circuit board, resulting in inaccurate soldering positioning and poor solder joints. This not only increases the scrap rate of circuit boards but also significantly reduces the efficiency of automated production. Therefore, these problems need to be solved. Utility Model Content

[0014] See Figures 1 to 4 This utility model discloses a PCB circuit board welding device, including a base and a processing chamber 1 fixed to the top surface of the base. Four support columns 2 are fixed at equal intervals at the four corners of the bottom of the base. The support columns 2 facilitate lifting the entire device off the ground, keeping the device in a stable horizontal state and preventing tilting due to uneven ground. This ensures that welding, flipping and other operations can be carried out on a stable basis, guaranteeing operational accuracy. A sliding groove 12 is provided at the bottom of the base, and a debris collection box 6 is slidably installed in the sliding groove 12. The debris collection box 6 facilitates timely collection of welding debris, preventing debris from accumulating at the bottom of the processing chamber 1 or scattering around the device, keeping the inside of the processing chamber 1 and the working environment clean. A safety door is hinged to one side of the processing chamber 1. Welding components are installed at the top inside the processing chamber 1, and two flipping structures are symmetrically arranged at the bottom inside the processing chamber 1.

[0015] In this invention, the welding component includes a first motor installed on one side of the processing chamber 1 and a lead screw 4 laterally rotatable at the top of the processing chamber 1. The output end of the first motor is coaxially fixed to one end of the lead screw 4. A moving block is sleeved on the lead screw 4, and a welding nozzle 3 is provided on one side of the moving block. The welding component facilitates precise application to the parts of the PCB circuit board to be welded, ensuring the electrical performance and structural stability of the PCB circuit board. An arc-shaped groove is provided at the bottom of the processing chamber 1 to facilitate the collection of debris. One end of a sliding groove 12 is connected to the arc-shaped groove. The sliding groove 12 facilitates the sliding of the debris collection box 6 along a fixed trajectory, making it easy to push the collection box 6 in and pull it out, ensuring that the collection box 6 can accurately align with the arc-shaped groove at the bottom of the processing chamber 1, thereby achieving effective collection of debris. Example

[0016] refer to Figures 2 to 3The flipping structure includes a mounting plate fixed to the bottom of the processing chamber 1 and a support plate 7 fixed to one side of the top of the mounting plate. A rotating shaft is rotatably mounted on the top of the support plate 7, and a rotating bearing is installed at the connection between the support plate 7 and the rotating shaft. A geared disc 5 is fixedly connected to one end of the rotating shaft, and a rotating disk 9 is fixedly connected to one side of the geared disc 5. A fixing frame 8 is symmetrically arranged on one side of the rotating disk 9. The flipping structure facilitates multi-angle flipping of the PCB circuit board while ensuring accurate positioning of the circuit board after flipping, without affecting subsequent soldering positioning. A hydraulic cylinder is installed at the bottom of the fixing frame 8, and a fixing plate is fixedly connected to the extended end of the hydraulic cylinder. Two buffer springs are provided on the mounting plate, and an abutment plate is fixedly connected to the top of the buffer springs. The abutment plate movably abuts against the circuit board. The fixing frame 8 facilitates the firm fixation of the circuit board and prevents the circuit board from shifting during soldering or flipping. A second motor is installed on the other side of the top of the mounting plate. The output end of the second motor is coaxially fixed to a connecting shaft. The connecting shaft is provided with a drive gear 10. Multiple positioning splines 11 for fixing are provided at the connection between the connecting shaft and the drive gear 10. The drive gear 10 facilitates the rotation of the rotating disk 9 and the PCB circuit board, ensuring sufficient power for the flipping action.

[0017] Working Principle: When using this utility model, first connect each electrical component in this application to the power supply. Then, open the safety door of the processing chamber 1 and place the PCB circuit board to be soldered in the fixed frame 8 of the rotating disk 9. Start the hydraulic cylinder at the bottom of the fixed frame 8. The hydraulic cylinder pushes the fixed plate upward, and the buffer spring drives the abutment plate to press the circuit board. The buffer spring will automatically adjust the pressure according to the thickness of the circuit board, ensuring that the circuit board is firmly fixed and avoiding damage caused by excessive pressure. Close the safety door, and the device enters the standby state. Then, the first motor starts and drives the lead screw 4 at the top of the processing chamber 1 to rotate. The lead screw 4 drives the moving block sleeved on it to move laterally through the threaded transmission. The welding nozzle 3 installed on one side of the moving block moves synchronously with the moving block. According to the preset program or manual control, the welding nozzle 3 moves precisely to the position to be soldered on the circuit board, releases the heat source and solder, and performs welding processing on the solder joint. At the same time, when it is necessary to... When performing double-sided soldering on a PCB circuit board, the second motor is started. The second motor drives the drive gear 10 to rotate through the connecting shaft at the output end. The connecting shaft and the drive gear 10 are firmly connected through the positioning spline 11 to ensure that the power is transmitted without slippage. The drive gear 10 meshes with the gear plate 5, driving the gear plate 5 and the connected rotating shaft to rotate. The rotating shaft rotates smoothly under the support of the rotating bearing at the top of the support plate 7, and at the same time drives the rotating disk 9 to rotate synchronously, realizing the flipping of the PCB circuit board within the fixed frame 8 to meet the double-sided soldering requirements. Finally, the solder slag, debris, etc. generated during the soldering process slide down the arc-shaped groove at the bottom of the processing chamber 1 into the slide groove 12 at the bottom of the base, and finally fall into the debris collection box 6 that slides along the slide groove 12. When the debris in the collection box 6 accumulates to a certain amount, the operator can pull it out from the slide groove 12 for cleaning, keeping the inside of the device and the working environment clean. This concludes the use of the flipping structure and the PCB circuit board soldering device.
