[0007] Furthermore, two unclamping blocks and two ejecting blocks are fixedly installed in the shell.

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

[0009] When the placement plate is located at the top opening block, the top opening block lifts 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, so that the clamping plate presses the industrial control mainboard onto the placement plate.

[0010] The inner electric cylinder extends, thereby driving the ratchet frame to move, and drives the driving ratchet, the lower driving shaft and the lower transmission wheel to rotate through the driving ratchet bar, and drives the upper transmission wheel, the driving shaft and the main conveying wheel to rotate through the inclined 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 forward once, and at this time the downward pressing ratchet bar contacts the downward pressing ratchet, and the downward pressing ratchet bar will slide upward along the ratchet frame, and the ratchet spring will be compressed, and the downward pressing ratchet will not rotate at this time; when the inner electric cylinder contracts, the downward pressing ratchet, the inner transmission shaft and the inner transmission wheel are driven to rotate through the downward pressing ratchet bar, and the upper wheel, the long gear shaft and the 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 under 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 is extended, 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 reset spring is compressed, and the extrusion spring is not compressed at this time. When the solder paste pool descends to fit the industrial control mainboard below it, the upper sliding column continues to descend, which will compress the extrusion spring. The rotation of the lead screw motor drives the rotation of the bidirectional lead screw, 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 mainboard.

[0017] Furthermore, the heat welding device includes a rotating motor fixedly mounted on the heat welding box, an inner frame fixedly mounted in the heat 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 mainboard, the conveyor belt moves the industrial control mainboard 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, thereby driving the hot air gun to swing back and forth around the inner frame, and the solder paste between the industrial control mainboard and the electronic components is heated through the inner frame to weld the electronic components to the industrial control mainboard.
