Technical Field

[0002] Industrial computer motherboards are computer motherboards designed specifically for industrial automation and control systems, and are commonly used in equipment in the fields of machinery, energy, transportation, communications, and healthcare. Unlike ordinary computer motherboards, industrial computer motherboards offer greater stability, durability, and anti-interference capabilities to adapt to complex industrial environments. Industrial computer motherboards typically contain numerous electronic components, and soldering these components is a high-precision, demanding process that directly impacts the motherboard's stability and performance. Soldering electronic components to motherboards is typically performed using soldering. Prior art soldering of electronic components on industrial control motherboards first requires manually applying solder paste to the motherboard. An automated robot or manual operator then places the electronic components to be installed in the soldered area. The industrial control motherboard and the electronic components are then soldered together. However, these steps often lack accurate automatic positioning and docking, and the process cannot be fully automated, resulting in a low level of automation. Summary of the Invention

[0008] Furthermore, two opening blocks are fixedly installed in the shell.

[0009] When the placement plate is located at the top opening block, the top opening block will lift the lifting column to lift the clamping plate. At this time, the industrial control mainboard is placed on the placement plate and positioned by the positioning column. When the lifting column leaves the top of the top opening block, the clamping spring rebounds, causing the clamping plate to press the industrial control mainboard onto the placement plate.

[0010] The inner electric cylinder extends, thereby driving the ratchet frame to move, and driving the driving ratchet, lower driving shaft and lower transmission wheel to rotate through the driving ratchet bar, and driving the upper transmission wheel, driving shaft and main conveying wheel to rotate through the oblique transmission belt, thereby driving the conveyor belt to move, and the conveyor belt drives the connecting plate and the placement plate to move, thereby driving the industrial control mainboard to move once, and at this time the downward ratchet bar contacts the downward ratchet, and the downward ratchet bar will slide upward along the ratchet frame, and the ratchet spring will be compressed, and the downward ratchet will not rotate at this time; when the inner electric cylinder contracts, the downward ratchet, inner transmission shaft and inner transmission wheel are driven to rotate through the downward ratchet bar, and the upper wheel, long gear shaft and lower transmission wheel are driven through the vertical transmission belt. The pressure gear rotates, and the lower pressure gear drives the lifting rack and the upper sliding column to descend, and the industrial control mainboard located below the solder paste pool is brushed with solder paste. At this time, after the driving ratchet bar contacts the driving ratchet wheel, the driving ratchet bar will not drive the driving ratchet wheel to rotate. The driving ratchet bar will slide upward relative to the ratchet rack under the action of the driving ratchet wheel, and the rack spring is compressed. That is, when the inner electric cylinder extends, the conveyor belt rotates once, driving the connecting plate and the placement plate forward once.

[0015] Furthermore, a solder paste pool is fixedly installed on the lifting frame, the solder paste pool is filled with solder paste, the solder paste pool is provided with holes corresponding to the welding positions on the industrial control mainboard, a screw motor is fixedly installed on the lifting frame, a track column is fixedly installed on the lifting frame, a bidirectional screw is rotatably installed on the lifting frame, a scraper is slidably installed on the track column, an internal thread is provided in the scraper, the scraper and the bidirectional screw form a threaded transmission, and the scraper is in contact with the upper surface of the solder paste pool.

[0016] When the lifting rack and the upper sliding column descend, the lifting frame is driven down through the lower pressure plate and the extrusion spring, the return spring is compressed, and the extrusion spring is not compressed at this time. When the solder paste pool drops to fit the industrial control motherboard below it, the upper sliding column continues to descend, which will compress the extrusion spring. The rotation of the lead screw motor drives the bidirectional lead screw to rotate, thereby driving the scraper to slide back and forth, and the scraper squeezes the solder paste in the solder paste pool through the holes in the solder paste pool and onto the industrial control motherboard.

[0017] Furthermore, the hot welding device includes a rotating motor fixedly mounted on the hot welding box, an inner frame fixedly mounted in the hot welding box, an eccentric connecting block fixedly mounted on the motor shaft of the rotating motor, an oblique rotating frame rotatably mounted on the eccentric connecting block, a hot air gun rotatably mounted on the oblique rotating frame, and an inner frame rotatably mounted on the hot air gun.

[0018] After the robot arm places all the electronic components on the industrial control motherboard, the conveyor belt moves the industrial control motherboard to the bottom of the hot soldering box in the next movement. The rotating motor drives the eccentric connecting block to rotate, thereby driving the inclined rotating frame to rotate, and then driving the hot air gun to swing back and forth around the inner frame.
