Description

Technical Field

[0001] The invention relates to the technical field of electronic component welding, in particular to a welding device for processing electronic components. Background Art

[0002] Electronic components are a general term for electronic components and electronic devices. Electronic components include resistors, capacitors, inductors, potentiometers, etc. They play the role of current limiting, voltage dividing, filtering, energy storage, etc. in the circuit. Electronic devices include diodes, triodes, integrated circuits, etc., which have functions such as amplification, switching, rectification, and voltage stabilization.

[0003] With the rapid development of electronic technology, electronic components are being used more and more widely in various fields. In the processing of electronic components, welding is a crucial process. The welding device plays a vital role in the production process of electronic components. It can accurately connect different electronic components together to ensure the integrity and stability of the circuit.

[0004] The prior art publication number is CN116900438B, which provides a welding device for processing electronic components, including a welding workbench, on which a workpiece placement area is provided, and also includes: a V-shaped bracket, which is fixedly installed on the welding workbench; and a component welding mechanism, which is respectively connected to the welding workbench and the V-shaped bracket, wherein the component welding mechanism includes a moving component, an adjustment support plate and a welding component; the welding component includes a driving unit, a differential conversion unit and a flux injection unit. The welding device for processing electronic components can save welding work time for multiple fixed solder joints, thereby improving welding work efficiency, and fully and appropriately injects flux in a slow rotation cycle, and drives the soldering iron to quickly turn away from the solder joint in a fast rotation cycle, which can reduce the probability of welding defects and ensure welding quality.

[0005] Although the above-mentioned prior art can save the welding time of multiple fixed soldering points and improve the welding efficiency, it cannot avoid the situation where the molten flux drips onto the welding plate. When welding electronic components such as circuit boards, the welding wire is heated by a welding gun to melt it and drip onto the electronic components to be welded. However, after the existing equipment heats the welding wire, the position of the soldering point will be moved quickly. The moving welding wire is very likely to drip the unsolidified flux onto the circuit board, making it difficult to clean up later and may also cover the installed electronic components. In addition, the existing welding wire is generally unwound or extruded by roller transportation. However, when the diameter of the welding wire is different, the roller transportation may press the welding wire to deformation, which cannot cooperate well with the welding gun.

[0006] It can be seen that a welding device for processing electronic components is needed to solve the problems mentioned in the above background technology that the welding wire remains extended during processing, the flux may drip onto the welding plate during movement, and the roller for transporting the welding wire cannot be adjusted.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 4 A welding device for processing electronic components includes a base plate 1, a welding frame assembly 2 is installed on the top of the base plate 1, and the welding frame assembly 2 includes three groups of free frames with the same structure, and the ends of the three groups of free frames are jointly hinged to a welding gun 3.

[0036] In this embodiment, the three groups of free frames are the first free frame 201, the second free frame 202 and the third free frame 203. The first free frame 201, the second free frame 202 and the third free frame 203 are equidistantly arranged around the annular ring, and the welding gun 3 is in the middle. By individually controlling the motors on the three groups of free frames to start, the three groups of free frames can be rotated separately, the articulated frame 2017 can be rotated or the column 2014 can be rotated, so as to adjust the welding direction, height, angle, etc. of the welding gun 3. A controller is installed in the device, and the controller is electrically connected to the motor in the device, which is convenient for direct control, and the individual control has a high degree of freedom and flexibility.

[0037] Specifically, the welding frame assembly 2 includes a first free frame 201, a second free frame 202 and a third free frame 203, and the first free frame 201, the second free frame 202 and the third free frame 203 are equidistantly arranged on a common circular ring, and the first free frame 201 includes a welding motor 2011, the output end of the welding motor 2011 is connected to a small pulley 2012, and the small pulley 2012 drives a large pulley 2013 through a belt, and the top of the large pulley 2013 is hinged with a column 2014, and an inner pulley 2015 is arranged at a middle position inside the column 2014, and the inner pulley 2015 is connected to an outer pulley 2016 through a belt, and the outer pulley 2016 is located at the top of the column 2014.

[0038] In this embodiment, the welding motor 2011 is started to drive the small pulley 2012 to rotate, and the small pulley 2012 drives the large pulley 2013 to rotate through the belt. The rotation of the large pulley 2013 also drives the upper column 2014 to rotate. The column 2014 is hinged to the large pulley 2013 at the same time, so the column 2014 will not only rotate with the large pulley 2013 but also tilt to a certain extent on the large pulley 2013. The tilting, rotation, and rotation of the articulated frame 2017 can enable the three sets of free frames to perform any action when welding electronic components.

[0039] Specifically, an articulated frame 2017 is connected to the outer side of the column 2014, and an articulated ball 2018 is connected to one end of the articulated frame 2017. The number of the articulated balls 2018 is three groups, and the three groups of articulated balls 2018 are equidistantly arranged on the outer side of the welding gun 3.

[0040] In this embodiment, a motor is installed on the rear side of the inner pulley 2015. When the motor is started, it drives the inner pulley 2015 to rotate. The inner pulley 2015 drives the outer pulley 2016 to rotate through the belt, so that the outer pulley 2016 rotates at the top of the column 2014, driving the articulated frame 2017 to rotate. The articulated ball 2018 at the end of the articulated frame 2017 meets the connection requirements of different angles. The three sets of free frames can enable the welding gun 3 to perform free welding within a certain degree.

[0041] See also Figure 5-Figure 7A welding device for processing electronic components, a material unwinding reel 4 is arranged on one side of the free frame, the welding wire 513 wound on the outer side of the material unwinding reel 4 passes through the material unwinding assembly 5 to reach the bottom of the welding gun 3, and a storage sleeve 514 is arranged on one side below the welding gun 3, the material unwinding assembly 5 includes a rotating upper roller 502 and a lower roller 5023, and both ends of the upper roller 502 are connected to a moving block 5021, a screw rod 5022 runs through the moving block 5021, and the rear side of one group of the moving blocks 5021 is connected to a first gear 503, and a second gear 504 is arranged below the first gear 503, one side of the first gear 503 is meshed with the third gear 505, and the third gear 505 is meshed with the fourth gear 506 below, the rear side of the first gear 503 is connected to the second articulated frame 508, and one end of the second articulated frame 508 is hinged in the first articulated frame 507, the rear side of the third gear 505 is connected to the side gear 509 through an axis, and one side of the side gear 509 is meshed with the half gear 510, and the outer side of the side gear 509 is meshed with the outer gear 512.

[0042] In this embodiment, the welding wire 513 passes between the rotating upper roller 502 and the lower roller 5023, and penetrates the storage sleeve 514 and extends to the outside thereof. The rotation directions of the upper roller 502 and the lower roller 5023 are opposite, so the welding wire 513 can be advanced or retreated by the rotating upper roller 502 and the lower roller 5023. The advancement and retreat of the welding wire depends on the rotation direction of the upper roller 502 and the lower roller 5023. The rotation direction of the upper roller 502 and the lower roller 5023 is controlled by the drive motor 511.

[0043] Specifically, the material collecting and releasing component 5 includes a mounting shell 501, and grooves are provided on both sides of the mounting shell 501, the moving block 5021 is located inside the groove, the screw rod 5022 passes through the mounting shell 501 and extends to its outside, and the top of the screw rod 5022 is connected to a hand wheel, and shafts are provided at both ends of the lower roller 5023, and the lower roller 5023 is installed inside the mounting shell 501 through the shaft and bearings.

[0044] In this embodiment, rotating the handwheel causes the moving block 5021 to lift in the slot, thereby driving the entire upper roller 502 to lift inside the mounting housing 501. The lifting of the upper roller 502 can adjust the distance between the upper roller 502 and the lower roller 5023, allowing welding wires of different diameters to pass through. This can prevent the problem of the internal gap between the upper roller 502 and the lower roller 5023 being too small and squeezing the welding wire to cause deformation. The welding wire with a diameter within a certain range can be transported, making the device highly flexible and widely adaptable. Threaded holes are provided in the upper part of the slot in the mounting housing 501, and the threaded holes match the lead screw 5022. When the handwheel is rotated, it drives the lead screw 5022 to lift inside the mounting housing 501, thereby driving the moving block 5021 to lift inside the slot. The size of the slot matches the moving block 5021, which plays a limiting role. Both ends of the upper roller 502 are installed on one side of the moving block 5021 through shafts and bearings.

[0045] Specifically, the second gear 504 meshes with the fourth gear 506, and the third gear 505 also meshes with the fourth gear 506. The rear side of the fourth gear 506 is connected to the first hinge bracket 507, and the first hinge bracket 507 is located in front of the side gear 509.

[0046] In this embodiment, the rotation of the upper roller 502 is directly controlled by the first gear 503, and the rotation of the lower roller 5023 is controlled by the second gear 504. However, the first gear 503 is driven by the third gear 505, and the second gear 504 is driven by the fourth gear 506. There is no necessary connection relationship between the first gear 503 and the second gear 504. Therefore, when adjusting the gap between the two sets of rollers, it is no problem that the first gear 503 does not directly contact the second gear 504.

[0047] Specifically, a driving motor 511 is installed on the rear side of the half gear 510, and the output end of the driving motor 511 is connected to the external gear 512 through a connecting frame. The external gear 512 includes teeth and a mounting ring, and the teeth are located inside the mounting ring and are not completely installed. The teeth mesh with the side gear 509.

[0048] In this embodiment, the second hinge bracket 508 rotates on one side of the first hinge bracket 507, that is, the first gear 503 rotates on one side of the third gear 505. After the first gear 503 revolves around the third gear 505 for a certain distance, it is then driven by the third gear 505 to rotate. The position of the first gear 503 on the outside of the third gear 505 is not fixed and depends on the gap between the two sets of rollers to be adjusted. During the adjustment process, since the third gear 505 is always in mesh with the fourth gear 506, and the fourth gear 506 is in mesh with the second gear 504, the rotation of the lower roller 5023 is not affected during the adjustment process.

[0049] Specifically, the welding wire 513 passes through the storage sleeve 514 and extends to the outside thereof, and the interior of the storage sleeve 514 is hollow.

[0050] In this embodiment, the storage sleeve 514 provides a shield for the recycled welding wire 513. If the welding wire is not solidified after welding, it will directly enter the interior of the storage sleeve 514 when it is recycled. The dripping flux will not be directly located on the welding pad, but inside the storage sleeve 514, which can avoid later repairs. In this embodiment, the teeth in the half gear 510 can occupy one-quarter of the position of the half gear 510, and the corresponding teeth in the outer gear 512 occupy three-quarters of the outer gear 512. The specific proportion can be adjusted according to the welding wire delivery requirements. When the degree of recovery is adjusted, the meshing of the teeth in the half gear 510 and the side gear 509 will drive the recovery of the welding wire. The length of the recovered welding wire does not need to be very long, because the welding wire will melt a section when heated by the welding gun, so it will be shorter, and the distance for recovery into the storage sleeve 514 naturally does not need to be very long. The teeth of the outer gear 512 account for a larger proportion because the meshing with the side gear 509 can drive the advancement of the welding wire, and the advancement length of the welding wire is longer. In this process, the side gear 509 is driven to rotate in opposite directions by the half gear 510 and the outer gear 512.

[0051] See also Figure 8-Figure 10 , a welding device for processing electronic components, a flip assembly 6 is installed below the welding gun 3.

[0052] In this embodiment, the storage slot 610 in the flip assembly 6 is used to place electronic components to be welded. A flexible clamp can be installed inside the slot. After placing electronic components such as circuit boards inside, the purpose of clamping can be achieved and the electronic components can be fixed. The upper baffle plates 611 and the lower baffle plates 612 on the upper and lower sides support the electronic components from below, making the welding process more stable. The shape of the slot is not limited by the attached drawings and can be determined according to on-site usage requirements.

[0053] Specifically, the flip assembly 6 includes a mounting frame 601, and the mounting frame 601 includes a bottom plate and three vertical plates, the vertical plate is located at the top of the bottom plate, a flip motor 602 is installed at the top of the first vertical plate, and the output end of the flip motor 602 is connected to the output shaft 603, a bevel ring 604 is provided on one side of the second vertical plate, and a roller 605 rolls on the inclined surface of the bevel ring 604, one side of the roller 605 is connected to a connecting rod 606, and one side of the connecting rod 606 is connected to a spring rod 607.

[0054] In this embodiment, a worm gear reducer and a locking structure can be installed between the flipping motor 602 and the output shaft 603 to achieve a certain purpose of preventing reversal and positioning. The locking structure can be a ratchet pawl. The flipping motor 602 drives the output shaft 603 to rotate, so that the output shaft 603 drives the turntable 608 to rotate synchronously, while the bevel ring 604 does not rotate. Therefore, the height position of the two groups of rollers 605 located on the inclined surface of the bevel ring 604 will change when they move. The cross-section of the bevel ring 604 is a beveled circular ring structure. When the two groups of rollers 605 roll, a height position difference occurs, which drives the corresponding upper baffle plate 611 and lower baffle plate 612 to advance and pull back. The action cooperates with the rotating flip box 609 so that the flip box 609 flips while the upper baffle plates 611 and lower baffle plates 612 on both sides push and pull. When the flip box 609 is facing up, the upper space is exposed and there is a support below.

[0055] Specifically, one end of the output shaft 603 is connected to a turntable 608, and the turntable 608 is located inside the third vertical plate, one side of the turntable 608 is connected to a flip box 609, and a storage groove 610 is opened inside the flip box 609, an upper baffle 611 is arranged above the storage groove 610, and a lower baffle 612 is arranged below the storage groove 610.

[0056] In this embodiment, a through plate is disposed on the inner side of the upper baffle 611 and the lower baffle 612 . The through plate penetrates the rotating disk 608 and extends to the rear side thereof. The two sets of through plates are respectively connected to a set of spring rods 607 .

[0057] Specifically, a card slot is opened inside the flip box 609, and the upper baffle 611 and the lower baffle 612 are located inside the flip box 609 and slide at the upper and lower ends of the card slot. The upper baffle 611 and the lower baffle 612 pass through the turntable 608 and move inside it.

[0058] In this embodiment, the slot position of the storage slot 610 is the welding position corresponding to the welding gun 3. During welding, the upper baffle 611 or the lower baffle 612 located above will move to one side of the slot and will not affect the welding.

[0059] When in use, it is necessary to connect to an external power supply, which provides power to the device so that the device can operate normally. The electronic components to be welded are placed in the card slot in the storage slot 610, and the card slot locks them. The lower baffle 612 below provides support for the electronic components. The welding gun 3 above is ready to weld them. When welding, the welding gun 3 will heat the welding wire 513 on one side to melt it, and the flux will drip on the place where the electronic components are installed to complete the welding. The welding wire 513 will be short after welding for a period of time, so it is necessary to start two sets of rollers to transport the welding wire. The welding wire may not solidify after welding, so the welding wire needs to be recovered first and then advanced forward. The process is to start the driving motor 511, and the driving motor 511 drives the half gear 510 to rotate. When the tooth portion of the half gear 510 contacts the side gear 509, the side gear 509 is driven to rotate, so that the rotation of the side gear 509 drives the third gear 505 to rotate, so that the third gear 505 drives the first gear 503 to rotate, and the first gear 503 drives the upper roller 502 to rotate. At the same time, the third gear 505 The fourth gear 506 meshing with it will also be driven to rotate, and the fourth gear 506 will drive the second gear 504 meshing on one side to rotate, and the second gear 504 will drive the lower roller 5023 to rotate, so that the welding wire 513 passing through the middle is recycled for a distance, and the end of the welding wire 513 is recycled into the storage sleeve 514 to prevent the unsolidified flux from dripping on the welding plate. The recycling rotation of the upper roller 502 and the lower roller 5023 is achieved by the contact and meshing of the half gear 510 and the side gear 509, but the half gear 510 is an incomplete tooth ring. When the half gear 510 ends the meshing state with the side gear 509, the driven motor 511 drives the outer gear 512 to rotate, and the teeth inside the outer gear 512 mesh with the side gear 509, so it drives the side gear 509 to rotate in the opposite direction, and the upper roller 502 and the lower roller 5023 also cause them to rotate in the opposite direction for a longer time, so that the welding wire in the middle is advanced to one side of the welding gun 3, and the time for the welding wire to be recovered and entered into the storage sleeve 514 is enough for the welding wire to condense, and it continues to be advanced to one side of the welding gun 3 so that the next welding can be smoothly carried out;

[0060] During welding, the welding motor 2011 is started to drive the small pulley 2012 to rotate, and the small pulley 2012 drives the large pulley 2013 to rotate through the belt, so that the entire column 2014 rotates to a certain extent. A motor is also installed on one side of the inner pulley 2015. After starting, it will drive the inner pulley 2015 to rotate, and the outer pulley 2016 can be driven to rotate through the belt. The rotation of the outer pulley 2016 drives the articulated frame 2017 to rotate. The first free frame 201, the second free frame 202 and the third free frame 203 are started at the same time and cooperate with each other. The middle welding gun 3 can be adjusted to any position, any height and any angle through the articulated ball 2018, so as to facilitate the welding of different angles and positions of the electronic components below;

[0061] If double-sided welding is required, the flip motor 602 can be started, and the flip motor 602 drives the turntable 608 to rotate through the output shaft 603, and the turntable 608 drives the flip box 609 to rotate as a whole, thereby driving the electronic components placed inside the flip box 609 to flip, and at the same time, the rotation of the flip box 609 will also drive the upper baffle 611 and the lower baffle 612 to rotate, and when the upper baffle 611 and the lower baffle 612 rotate, they will respectively drive the two sets of spring rods 607 to rotate, and when the spring rods 607 rotate, the height of the two sets of rollers 605 on the inclined surface of the inclined surface ring 604 is The positions are different, so the height position of the roller 605 will also change when it rotates. When the roller 605 originally located at the lower position of the bevel circle 604 rolls to the highest point, it will drive the corresponding upper baffle 611 or lower baffle 612 to advance through the connecting rod 606 and the spring rod 607, so that the upper baffle 611 and the lower baffle 612 advance and retreat inside the flip box 609, so that when the flip box 609 is turned over, the upper baffle 611 and the lower baffle 612 move forward and backward as a group, exposing the upper space for easy welding and blocking the lower space to provide support for the placed electronic components.
