[0002] Electronic access control is a modern access management device that uses electronic technology to control and manage doors. It is usually composed of a controller, card reader, electromagnetic lock, power supply and other components. The card reader can read card information, such as ID card, IC card, radio frequency card, etc., and transmit the information to the controller for verification. After verification, the controller will send a signal to open the electromagnetic lock and allow people to enter. Electronic access control has the advantages of safety, reliability, convenience, and efficient management. It can effectively prevent illegal entry and protect the safety of people and property. At the same time, it can also record the entry and exit information of people, which is convenient for managers to query and count. Electronic access control is widely used in enterprises, schools, hospitals, communities and other places;

[0003] Electronic access control machines require welding during assembly. The welding of electronic components of electronic access control machines is the process of connecting various electronic components to the circuit board through soldering. Usually manual welding or machine welding is adopted. Electric soldering irons, solder wires and other tools are needed to solder the pins of electronic components to the pads on the circuit board. During the welding process, the welding quality must be guaranteed to make the soldering points smooth and firm to avoid problems such as cold soldering and short circuit. During welding, if the electric soldering iron is offset from the welding position, it is easy to affect the welding effect. Therefore, we proposed a welding equipment with correction effect for the assembly of electronic access control machines. Summary of the invention

Then the assembly is rotated back, the soldering iron is turned off, the soldering iron is cleaned, preheated again and the soldering wire is attached, and the welding is repeated. The soldering is performed according to the distance between the pins of the electronic components and the soldering iron in the circumferential and radial directions. The soldering is started from the electronic component that is farthest in both the circumferential and radial directions, so that the soldering iron can complete the welding of all pins without repeated movement.

The hollow plate 341 slides on the top of the base 1, driving the plate body 347 to move and the spring 346 to stretch, thereby buffering the movement of the hollow plate 341.

[0052] A slide groove 348 is symmetrically provided on one side of the base 1 close to the hollow plate 341, and a slide groove 348 is symmetrically provided directly below the hollow plate 341. Slide plates 349 are symmetrically provided inside the slide groove 348, and the surface of the slide plate 349 slides with the inner side surface of the slide groove 348 in a limited manner. The side of the slide plate 349 away from the shell 4 is fixedly connected to the side of the hollow plate 341 close to the base 1, and the interior of the slide plate 349 is hollow, and the inner cavity of the slide plate 349 is connected with the inner cavity of the hollow plate 341. The movement of the hollow plate 341 drives the slide plate 349 to move, and the slide plate 349 slides in a limited manner inside the slide groove 348, thereby limiting the movement of the hollow plate 341 and avoiding shaking when the hollow plate 341 moves.

[0053] The inner side surface of the hollow plate 341 is fixedly connected to the frame 3411, and the inner side surface of the frame 3411 is fixedly connected to the ridge plate 3410, and the ridge plate 3410 is arranged between two symmetrical slide grooves 348. After the welding slag is sucked into the hollow plate 341, it can slide along the ridge plate 3410 and finally enter the hollow structure of the slide plate 349, which can concentrate the welding slag to both sides, avoid the welding slag from accumulating inside the hollow plate 341 and causing blockage, thereby ensuring the adsorption and fixing effect.

[0054] The air suction assembly 35 includes a flat tube 351, and a plurality of slide grooves 348 are provided with a flat tube 351 on one side close to the shell 4. The flat tube 351 is fixedly connected to the side of the base 1 close to the shell 4. The surface of the shell 4 is provided with holes 352, and the holes 352 are evenly distributed along the circumference of the shell 4. The inside of the shell 4 is provided with blades 353, and the blades 353 are arranged in a backward tilting manner. A plurality of holes 352 are arranged on the side of the blades 353 away from the base 1. A rotating shaft 354 is fixedly connected to the side of the blades 353 away from the inner side surface of the shell 4. The rotating shaft 354 is fixedly connected to the side of the base 1 close to the shell 4. One end of the rotating shaft 354 away from the base 1 extends to the outside of the shell 4, and the surface of the rotating shaft 354 is rotatably connected to the inner side surface of the shell 4. An air suction motor 355 is fixedly connected to one end of the rotating shaft 354 located outside the shell 4, and the output end of the air suction motor 355 is fixedly connected to the rotating shaft 354. A fixing frame 356 is fixedly connected to the surface of the air suction motor 355. The fixing frame 3 56 is fixedly connected to the side of the housing 4 away from the base 1, and the air suction motor 355 is started. The output end of the air suction motor 355 drives the rotating shaft 354 to rotate, and the rotation of the rotating shaft 354 drives the fan blade 353 to rotate. The fan blade 353 is backward-inclined and generates suction during rotation. The sucked welding slag and smoke enter the housing 4 through the flat tube 351, and the sucked air and smoke are discharged from the hole body 352 to ensure the smooth generation of suction. The welding slag is stored inside the housing 4. At the same time, when the welding slag reaches the side of the fan blade 353 The welding slag is blown toward the outermost side of the shell 4 by the fan blades 353, and is collected inside the shell 4. Since the welding slag has a low hardness and a small volume, when part of the welding slag contacts the fan blades 353, it will not cause damage to the fan blades 353. The fan blades 353 drive the air flow, which can quickly cool the welding slag that is not completely solidified inside, avoiding splashing when the welding slag hits the shell 4 or the fan blades 353, and avoiding splashing of the welding slag from adhering to the hole body 352, thereby avoiding clogging of the hole body 352, thereby ensuring the generation of suction.

[0055] When in use, the air suction structure of the fixing component 34 generates suction, which drives the hollow plate 341 to generate suction inside, and the soldering pad is placed on the top of the rubber ring 342. The soldering pad covers the rubber ring 342, thereby generating a certain adsorption on the soldering pad. Then, the pin of the electronic component is docked at the welding point of the soldering pad through tweezers or a clamping robot arm. Then, the electric soldering iron 31 is preheated. While preheating, a soldering wire is adhered to the contact position between the electric soldering iron 31 and the pin of the electronic component, that is, the end of the electric soldering iron 31. The soldering wire partially melts and adheres to the electric soldering iron 31. The reciprocating motor 321 is started, and the output end of the reciprocating motor 321 drives the reciprocating motor 321 to move back and forth. The rotating shaft 322 rotates, and after the reciprocating rotating shaft 322 rotates a certain angle, it stops after reaching the welding position, and the pin is welded. Then the reciprocating motor 321 quickly reverses and returns to the middle position, the electric soldering iron 31 is turned off, the electric soldering iron 31 is cleaned, preheated again and the welding wire is attached. At this time, the electric soldering iron 31 continues to move to another pad and weld, and then returns to the middle position again, and repeats the welding of half of the electronic components on the pads on both sides. While welding, the air suction motor 355 is started, and the output end of the air suction motor 355 drives the rotating shaft 354 to rotate, and the rotation of the rotating shaft 354 drives the fan blades 353 rotates, and the fan blades 353 are backward-inclined. Suction is generated during rotation. Smoke and welding slag are generated during welding, and are adsorbed by the hollow plate 341 from the remaining uncovered rubber ring 342. After the welding slag is sucked into the hollow plate 341, it can slide along the ridge plate 3410 and finally enter the hollow structure of the slide plate 349. The sucked welding slag and smoke enter the shell 4 through the flat tube 351. The sucked air and smoke are discharged from the hole body 352 to ensure the smooth generation of suction. The welding slag is stored in the shell 4. The fan blades 353 drive the air flow to remove the incompletely solidified particles in the shell 4. The welding slag is cooled rapidly, and when the welding slag reaches the side of the fan blade 353, it is blown by the fan blade 353, and the welding slag is blown to the outermost side of the shell 4, and the welding slag is collected inside the shell 4. After a welding pad is welded, it is moved to the top of the inclined plate 343, and slides along the inclined plate 343, and finally contacts the bent rod 344. The V-shaped bent rod 344 limits the welding pad, and then fixes another welding pad. When the previous welding pad is welded by the next welding pad, it is cooled at the top of the inclined plate 343. The cooled welding pad is removed, and the next welding pad that has been completed is moved to the top of the inclined plate 343 again, and then the material is loaded again.
