Description

Technical Field

[0001] The present invention relates to the application technology of welding jigs, and particularly to a circuit board processing and welding device. Background Art

[0002] A circuit board refers to a support substrate for fixing circuit structures and components. It is widely used in electronic products such as computers, mobile phones, and household appliances. The circuit board is an indispensable and important part of electronic products. It fixes and interconnects various electronic components so that these components can work together to perform various functions of the product. After long-term use, due to heat and aging, the components on the circuit board, such as chips, resistors, capacitors, etc., will be damaged to varying degrees. The insulating layers covering the surfaces of some components will crack, and the solder joints of the components will become loose or disconnected, affecting the normal operation of the circuit. At this time, it is necessary to remove the damaged components and manually weld new components to repair the circuit board to ensure the normal use of the product. Some of the existing welding devices use manual welding to repair the circuit board, melting and welding the problem parts of the circuit board with a hand-held soldering gun. There are also some welding devices that place the circuit board on the working surface, use a manipulator to shift, and perform welding operations with the manipulator holding the soldering gun. There are some problems. Welding will generate harmful smoke, which will cause damage to the operator's body during long-term work. Slight displacement of the circuit board during welding will affect the welding quality. With the trend of electronic products being small, thin, and light, the circuit board processing technology is becoming increasingly sophisticated, and the plug-in welding is constantly facing new technical requirements. The current mainstream material composite stone jigs, fiberglass (FR4) jigs, and titanium alloy jigs all have obvious advantages and disadvantages, and need to be further innovatively applied, taking into account the advantages of these jigs and making up for the deficiencies of a single material to further improve economy and timeliness. At the same time, when the existing welding jigs are used for welding, a large amount of welding fume will be generated. If the welding fume is inhaled by the user in large quantities, it will cause physical harm. At the same time, the welding jigs cannot be quickly cooled in time after use, and accidental contact by other users will cause harm. For this reason, we have proposed a circuit board processing and welding device. Summary of the Invention

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0032] Embodiment, refer to Figures 1-7 : A circuit board processing and soldering device, including a solder gun body 1, and further including:

[0033] The control box 2 is fixedly connected to one side of the soldering gun body 1 and is used for controlling the operation of the welding equipment. The control box 2 has a built-in energy storage battery, which outputs power to the dual-axis motor 401;

[0034] The smoke exhaust air cooling mechanism 3 is located at the bottom of the control box 2 and is used for adsorbing smoke when the soldering gun body 1 is soldering and for air cooling the soldering gun body 1 when it is idle. The smoke exhaust air cooling mechanism 3 includes an adsorption box 301 fixedly connected to the bottom of the control box 2 and a fan blade 303 movably sleeved inside the adsorption box 301, and also includes a driven rod 302 rotatably connected to the inside of the adsorption box 301. The fan blade 303 is fixedly connected to one end of the driven rod 302, and the other end of the driven rod 302 is fixedly connected to a second sprocket 404, and a chain 405 is transmission-connected between the outside of the second sprocket 404 and the first sprocket 403;

[0035] It is worth mentioning that an accelerator is arranged between the dual-axis motor 401 and the driven rod 302 to increase the rotation speed of the driven rod 302, thereby ensuring that the fan blade 303 rotates quickly to generate negative pressure inside the adsorption box 301, and the welding smoke generated by the welding of the tin soldering gun body 1 is attracted by the negative pressure, or a reducer is arranged between the dual-axis motor 401 and the worm 601 to slow down the rotation speed of the worm 601, thereby ensuring that the worm wheel 609 meshing with the worm 601 can rotate slowly, thereby driving the transmission rod 602 to rotate slowly, thereby ensuring that the linkage plate 502 is slowly opened or closed (adding an accelerator or a reducer to adjust the speed difference is a prior art solution, so this technical solution does not describe and elaborate on the working principle);

[0036] The protective isolation mechanism 5 is located on one side of the adsorption box 301, and is used to shield the tin point tip of the tin soldering gun body 1 and prevent tin dripping. The protective isolation mechanism 5 includes two connecting rods 501 symmetrically connected to one side of the adsorption box 301 and a linkage plate 502 fixedly connected to the two connecting rods 501, and also includes a transmission rod 602 connected to one side of the adsorption box 301, and the two ends of the transmission rod 602 are respectively fixedly connected to the second bevel gear 603, and the two connecting rods 501 are respectively fixedly connected to the two second bevel gears 603. The third bevel gear 504 is meshed with the second bevel gear 603 for transmission. One end of the two linkage plates 502 is respectively fixedly connected to the baffle plate 503, and the welding head of the tin soldering gun body 1 is blocked by the baffle plate 503 to prevent the dripping of solder.

[0037] The driving mechanism 4 is inside the control box 2 and is used to output power to the protection and isolation mechanism 5 and the smoke exhaust and air cooling mechanism 3. An start-stop control mechanism 6 is provided between the driving mechanism 4 and the protection and isolation mechanism 5. One end of the driving mechanism 4 is connected to the smoke exhaust and air cooling mechanism 3. The driving mechanism 4 includes a double-shaft motor 401 fixedly connected to the inside of the control box 2. One output end of the double-shaft motor 401 is fixedly connected to a driving shaft 402, and a first sprocket 403 is fixedly connected to the driving shaft 402. The other output end of the double-shaft motor 401 is fixedly connected to a first bevel gear 406. When the double-shaft motor 401 starts, it drives the synchronous rotation of the driving shaft 402, the first sprocket 403, and the first bevel gear 406 respectively.

[0038] In the present invention, the start-stop control mechanism 6 includes a worm 601 rotatably connected to one side of the adsorption box 301. A worm gear 609 is fixedly connected to the transmission rod 602 corresponding to the worm 601. One side of the worm gear 609 meshes with the worm 601 for transmission. One end of the worm 601 is fixedly connected to a first staggered tooth disc 607. The rotation of the worm 601 drives the synchronous rotation of the worm gear 609 (the staggered tooth disc is an existing component, and its specific use and operating principle belong to the prior art. Therefore, this technical solution does not describe in too much detail the working process of the engagement and separation of the staggered tooth disc).

[0039] In the present invention, a driving rod 604 is rotatably connected to the control box 2. One end of the driving rod 604 is fixedly connected to a fourth bevel gear 605. One side of the fourth bevel gear 605 meshes with the first bevel gear 406 for transmission. The other end of the driving rod 604 is movably sleeved with a second staggered tooth disc 606. One side of the second staggered tooth disc 606 engages with the first staggered tooth disc 607. A resistance spring 608 is provided between one side of the second staggered tooth disc 606 and the bottom of the control box 2. One end of the driving rod 604 is movably sleeved inside the resistance spring 608, and the second staggered tooth disc 606 is limited in movement by the resistance spring 608.

[0040] In the present invention, an activity opening is provided on the second staggered tooth disc 606. Limiting openings are symmetrically provided inside the activity opening. A limiting strip is fixedly connected to one end of the driving rod 604 corresponding to the limiting opening. One end of the driving rod 604 is movably sleeved inside the activity opening, and the limiting strip is movably sleeved inside the limiting opening. The rotation of the driving rod 604 drives the synchronous rotation of the second staggered tooth disc 606 through the abutment of the limiting strip and the limiting opening.

[0041] In the present invention, a discharge port is provided on one side of the adsorption box 301. A smoke exhaust pipe 305 is fixedly connected to the discharge port. The smoke exhaust pipe 305 is connected to an external gas purification device. A smoke suction port is provided at the bottom of the adsorption box 301. A telescopic adjustment pipe 304 is fixedly connected to the smoke suction port. An air outlet 306 is provided on the other side of the adsorption box 301. The welding fume generated during soldering of the soldering gun body 1 is sucked through the telescopic adjustment pipe 304 and discharged to the external purification device through the smoke exhaust pipe 305.

[0042] In the present invention, a mounting bracket 7 is fixedly connected to the top of the soldering gun body 1. The circuit board processing and welding equipment is fixedly installed on a handheld welding device or an automatic welding device through the mounting bracket 7.

[0043] Working principle: When in use, the circuit board processing and welding equipment is fixedly installed on a handheld welding device or an automatic welding device through the mounting bracket 7. After installation and fixation, when welding work is carried out, the biaxial motor 401 starts in the forward direction, thereby driving the drive shaft 402 and the first bevel gear 406 to rotate synchronously in the forward direction. The forward rotation of the drive shaft 402 drives the first sprocket 403 to rotate synchronously in the forward direction. The forward rotation of the first sprocket 403 drives the second sprocket 404 to rotate through the chain 405. The rotation of the second sprocket 404 drives the rotation of the driven rod 302 and simultaneously drives the rotation of the fan blade 303. When the fan blade 303 rotates in the forward direction, a negative pressure is generated inside the adsorption box 301, thereby sucking the welding fume generated during welding of the external soldering gun body 1 into the adsorption box 301 through the air outlet 306 and the telescopic adjustment pipe 304, and discharging it to the externally connected gas purification device for gas filtration treatment;

[0044] The forward rotation of the first bevel gear 406 drives the rotation of the fourth bevel gear 605. The rotation of the fourth bevel gear 605 drives the rotation of the drive rod 604, and at the same time drives the rotation of the second staggered tooth disc 606. The rotation of the second staggered tooth disc 606 drives the rotation of the first staggered tooth disc 607. The rotation of the first staggered tooth disc 607 drives the rotation of the worm 601. The rotation of the worm 601 meshes with the worm gear 609 to drive the rotation of the transmission rod 602. The rotation of the transmission rod 602 drives the synchronous rotation of two second bevel gears 603. The rotation of the second bevel gear 603 meshes with the third bevel gear 504 to drive the two connecting rods 501 to rotate outwards, thereby driving the linkage plate 502 to swing outwards, and at the same time driving the baffle 503 to separate towards both sides synchronously, so that the welding head of the soldering gun body 1 is exposed. When the linkage plate 502 flips upwards and abuts against both sides of the control box 2, the transmission rod 602 cannot continue to rotate, so the worm 601 cannot continue to rotate either. At this time, the second staggered tooth disc 606 cannot rotate normally and will move upwards along the drive rod 604. At the same time, the second staggered tooth disc 606 is moved downwards by the resistance spring 608, so that the second staggered tooth disc 606 reciprocates up and down along the drive rod 604 and does not engage with the first staggered tooth disc 607, ensuring the normal rotation of the drive rod 604, thus not interfering with the operation of the dual-axis motor 401, and ensuring the continuous rotation of the fan blade 303 to suck the welding fume;

[0045] When the welding is completed, the soldering gun body 1 will be in a high-temperature state. At this time, the dual-axis motor 401 starts in reverse, driving the drive shaft 402, the first sprocket 403 and the first bevel gear 406 to rotate synchronously in reverse. The reverse rotation of the first sprocket 403 drives the second sprocket 404 to rotate in reverse through the chain 405, thereby driving the reverse rotation of the driven rod 302 and the fan blade 303. Through the reverse rotation of the fan blade 303, the outside of the adsorption box 301 is blown, and the soldering gun body 1 is quickly cooled by air through the blowing of the fan blade 303;

[0046] At the same time, when the first bevel gear 406 rotates in reverse, it drives the drive rod 604 to rotate synchronously in reverse through the fourth bevel gear 605, and at the same time drives the second staggered tooth disc 606 to rotate in reverse and engage with the first staggered tooth disc 607. The rotation of the first staggered tooth disc 607 drives the rotation of the worm 601, and at the same time meshes with the worm gear 609. Through the rotation of the worm gear 609, the rotation of the transmission rod 602 is driven. The rotation of the transmission rod 602 drives the connecting rod 501 to rotate inwards, and at the same time drives the linkage plate 502 to flip inwards, and at the same time drives the two baffles 503 to close together in the middle, so as to carry out protective isolation treatment on the welding head of the soldering gun body 1.

[0047] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
