Description

Technical Field

[0001] The present invention relates to the technical field of welding, and in particular to an electronic component welding device based on bonding silver wire and a use method thereof. Background Art

[0002] Silver bonding wire is a thin wire made of high-purity silver and is widely used in electronic packaging. It has excellent electrical and thermal conductivity and is usually used for electrical connections between chips and substrates, such as on chip pins or solder joints.

[0003] At present, common welding devices are generally used to perform welding at multiple positions through multi-axis movement of the welding device, which is prone to uneven welding. In the process of flux spraying, liquid accumulation is easy to form on the surface, which is not conducive to uniform activation of the flux and affects the welding effect. The existing invention patent with patent announcement number CN118635617B discloses an electronic component welding device based on bonding silver wire and a method of using the same. The crankshaft is driven to rotate by a second motor, and the crankshaft drives the movable plate to swing through the third bearing and keeps the movable plate moving up and down, so that the movable plate drives the sealing plug to move up and down, and the sealing plug drives the connecting rod and the disc to move up and down, so that the disc drives the corrugated plate to rotate the roller. Squeeze, so that the bracket drives the movable frame to compress the spring. When the corrugated plate moves upward, the spring drives the movable frame to reset, so that the corrugated plate cooperates with the roller and the spring, and then drives the movable frame to vibrate. When the electronic components are sprayed with flux and transferred to the liquid removal station, the electronic components are kept vibrating, which can shake off the excess liquid on the surface of the electronic components and increase the fluidity of the flux on the electronic components, which is conducive to the uniform activation of the flux, thereby improving the subsequent welding quality. In addition, the electronic components should be kept vibrating during the welding process, which can improve the fluidity of the solder, improve the uniformity and strength of the welding, and secondly, the vibration can also help remove excess solder and prevent the problems of bridging and uneven welding.

[0004] However, this invention patent still has the following problems: the movable frame can only slide along a fixed direction and compress the spring and stretch the spring, so that the vibration direction of the movable frame is fixed, resulting in poor effect of removing accumulated liquid on electronic components and uniformity of flux flow, affecting the welding effect.

[0028] 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.

[0029] Embodiment 1:

[0030] like Figures 1 to 5 As shown, the present invention provides an electronic component welding device based on bonding silver wire, including a base 1, on which a welding mechanism 2 and a rotating device 3 are arranged, a circular welding bottom plate 4 is arranged on the top of the rotating device 3, an annular side plate 5 is arranged on the peripheral side of the base 1, and the peripheral side of the welding bottom plate 4 is slidably connected to the annular side plate 5, and the upper surface of the welding bottom plate 4 is evenly provided with a plurality of station slots 11 connected to the lower surface around its own center, each station slot 11 is slidably connected to a universal movable plate 6, and each universal movable plate 6 is movably provided There is a work station plate 7 for carrying the workpiece, and each work station plate 7 is elastically connected to the corresponding universal movable plate 6, and each work station plate 7 is provided with a fixing structure 8 for fixing the workpiece, and a plurality of pressing devices 9 are provided on the welding base plate 4 corresponding to the plurality of work station plates 7, and each pressing device 9 is used to press down in sequence along the circumference of the work station plate 7, and the work station plate 7 undergoes elastic deformation after being pressed and tilted, and a toggle structure 10 for toggle the universal movable plate 6 for movement is provided on the annular side plate 5, and the universal movable plate 6 can undergo elastic deformation after being toggled.

[0031] In actual application of the present application, multiple workstation plates 7 are provided, and different processes, such as cooling and unloading, are performed respectively. The number of workstation plates 7 is determined according to the actual number of processes. The welding mechanism 2 is used to weld the workpiece (electronic components), including a welding head device, a flux spraying device and a heating device, which are respectively located at different positions. Reference may be made to the welding machine mechanism in the electronic component welding device based on bonding silver wire and its use method disclosed in the invention patent with patent announcement number CN118635617B. The welding mechanism 2 is a prior art and will not be elaborated on here.

[0032] Furthermore, the present application may also provide a preheating device and a cooling device on the base 1. The preheating device is used for preheating the workpiece before the welding mechanism 2 heats the workpiece, and the cooling device is used to accelerate the cooling of the workpiece after the workpiece is welded. After the workpieces are rotated to the corresponding positions at the same angle in turn, the preheating device and the cooling device work in turn. Both are prior arts. For example, the preheating device may be a fan plus an electric heating wire. The wind force generated by the fan preheats the workpiece after passing through the electric heating wire, and the cooling device may be a direct blowing fan, etc., which will not be elaborated on here.

[0033] A plurality of workstation plates 7 are evenly arranged on the welding base plate 4, so the angle at which the rotating device 3 drives the welding base plate 4 to rotate each time is the same, that is, the size of the angle formed by connecting the center of the welding base plate 4 with the center of the adjacent workstation plates 7 and the center of the welding base plate 4 (the center of the welding base plate 4 is the vertex of the formed angle), the workpiece is placed on the workstation plate 7 and fixed by the fixing structure 8, and then the rotating device 3 drives the welding base plate 4 to rotate so that the workpiece rotates to above the position where the flux spraying device is located, after the flux spraying is completed, the rotating device 3 drives the welding base plate 4 to rotate the same angle (the same angle is the angle of rotation of the welding base plate 4 mentioned above, which has the same meaning as the same angle mentioned below), so that the subsequent workpiece placed can be sprayed with flux, at this time, the toggle structure 10 toggle the universal movable plate 6 to move and elastically deform, because the universal movable plate 6 can move in multiple directions, so that the universal movable plate 6 moves in multiple directions during the process of resetting by elastic force, thereby having a vibration effect, and then removing the residual accumulated liquid on the workpiece.

[0034] Then the rotating device 3 drives the welding base plate 4 to rotate again by the same angle until the workpiece is located at the heating device of the welding mechanism 2. After the welding mechanism 2 heats the workpiece, the rotating device 3 drives the welding base plate 4 to rotate so that the workpiece is located at the welding head device for welding. After the welding of the workpiece is completed, the rotating device 3 drives the welding base plate 4 to rotate to drive the workpiece to move to the next position for cooling and unloading.

[0035] During the workpiece welding process, the pressing device 9 presses down along the circumference of the workstation plate 7 in sequence, so that the workstation plate 7 tilts toward the circumference in sequence, and then the toggle structure 10 toggle the universal movable plate 6 to generate vibration, so that the flux on the workpiece can flow evenly in multiple directions, thereby improving the uniformity of the flux after melting, and then improving the welding quality of the workpiece. This process can be carried out before the welding mechanism 2 starts welding, so that the flux is evenly distributed. The toggle structure 10 can continuously toggle the universal movable plate 6 to generate vibration to make the flux evenly distributed.

[0036] The universal movable plate 6 includes a slide plate 601 slidably set in the work station groove 11, and the slide plate 601 slides in the horizontal direction. The slide plate 601 is provided with an installation groove 604 for installing the work station plate 7. The inner side wall of the work station groove 11 is provided with a first annular groove 602, and the slide plate 601 is slidably connected in the first annular groove 602. A plurality of first springs 603 are evenly arranged on the inner side wall of the first annular groove 602 around the center of the first annular groove 602, and each first spring 603 is connected to the peripheral side of the slide plate 601.

[0037] When the toggle structure 10 moves the universal movable plate 6, the slide plate 601 is subjected to the force applied by the toggle structure 10, thereby sliding along the inside of the first annular groove 602, squeezing the corresponding first spring 603 and stretching the corresponding first spring 603. When the toggle structure 10 is out of contact with the slide plate 601, the slide plate 601 continuously moves in different directions under the action of elastic forces in multiple directions, thereby forming vibrations in multiple directions, thereby improving the effect of removing accumulated liquid and making the flux evenly distributed due to the vibrations in multiple directions during welding.

[0038] Due to the restriction of the upper and lower inner walls of the first annular groove 602, the slide plate 601 can only slide in a direction parallel to the upper and lower inner walls of the first annular groove 602, that is, slide in a horizontal direction to avoid vibration in the upper and lower directions, thereby preventing the flux from detaching from the workpiece.

[0039] The workstation plate 7 includes a carrying plate 701 arranged in the mounting groove 604, a placement groove 704 for placing a workpiece is provided on the carrying plate 701, a processing groove 706 connected to the bottom of the carrying plate 701 is provided at the bottom of the placement groove 704, an annular frame 705 is provided on the top of the carrying plate 701, and the inner wall shape of the annular frame 705 is the same as the shape of the placement groove 704, the distance between the outer wall of the annular frame 705 and the inner wall of the mounting groove 604 is greater than zero, a second annular groove 702 is provided on the inner side wall of the mounting groove 604, and the peripheral edge of the carrying plate 701 is located in the second annular groove 702, a plurality of second springs 703 are evenly arranged on the inner bottom of the second annular groove 702 around the center of the carrying plate 701, and the top of each second spring 703 is connected to the bottom of the carrying plate 701, and when the carrying plate 701 is against the inner top of the second annular groove 702, the plurality of second springs 703 are in a compressed deformation state.

[0040] The workpiece is placed in the placement groove 704 , the fixing structure 8 presses down the upper surface of the workpiece to fix the workpiece, and the welding mechanism 2 performs welding processing on the bottom of the workpiece through the processing groove 706 .

[0041] When the slide plate 601 vibrates, the supporting plate 701 will be driven to move, thereby vibrating, and then the pressing device 9 presses down on the edge of the annular frame 705, so that the annular frame 705 tilts toward its own edge. Since the pressing device 9 presses down along the circumference of the annular frame 705 in sequence, the annular frame 705 tilts downward in sequence around its own center and in multiple directions, so that the flux on the surface of the workpiece can flow evenly to its own surface, and the vibration generated by the toggle structure 10 is used to improve the uniformity of the distribution of the flux during welding, thereby improving the welding quality.

[0042] When the annular frame 705 tilts to one side, the corresponding second spring 703 is compressed, and when the pressing device 9 presses down other positions on the annular frame 705, the previously squeezed position on the annular frame 705 can be automatically reset under the elastic force of the second spring 703, so that the annular frame 705 only tilts to one side when the pressing device 9 presses down, and the flux flows in an orderly manner under its own gravity and the vibration of the supporting plate 701 so as to be evenly distributed.

[0043] The distance between the annular frame 705 and the mounting groove 604 needs to be greater than zero to ensure that the annular frame 705 can tilt to one side.

[0044] When the pressing device 9 is not working, the bearing plate 701 abuts against the inner top of the second annular groove 702 under the elastic force of the plurality of second springs 703 , thereby maintaining stability.

[0045] The edge of the upper surface of the supporting plate 701 and the inner top of the second annular groove 702 can be attracted to each other by magnetic force.

[0046] Through the attraction of magnetic force, the carrier plate 701 can be quickly stabilized after being reset, and the welding stability is improved during welding.

[0047] The fixing structure 8 includes a bracket 801 arranged on the top of the annular frame 705, a fixing screw 802 is threadedly connected to the bracket 801, and a pressing plate 803 for pressing down the workpiece is arranged at the bottom of the fixing screw 802.

[0048] When the workpiece is located in the placement groove 704, the fixing screw 802 is rotated so that the fixing screw 802 drives the pressing plate 803 to gradually move downward until it contacts the upper surface of the workpiece, thereby fixing the workpiece.

[0049] The pressing device 9 includes a plurality of connecting frames 901 arranged on the welding base plate 4, and a plurality of telescopic devices 902 are arranged on the connecting frames 901, and the telescopic devices 902 perform telescopic movements in the vertical direction. The bottom of each telescopic device 902 is provided with a pressure strip 903 for pressing down the top edge of the annular frame 705.

[0050] After the same time interval, multiple telescopic devices 902 extend in sequence to drive the pressure strip 903 and then press down the annular frame 705. When the second telescopic device 902 extends downward, the first telescopic device 902 retracts and returns to its original position, so that the annular frame 705 is only subjected to the pressure of one pressure strip 903 at a time, and thus tilts downward in only one direction, so that the flux flows in an orderly manner and is evenly distributed.

[0051] In this embodiment, the telescopic device 902 is a conventional technology, such as an electric push rod, etc., which will not be elaborated in detail here.

[0052] The toggle structure 10 includes a mounting frame 101 arranged on the top of the annular side plate 5, a rotating device 102 is arranged on the mounting frame 101, an output end of the rotating device 102 is connected to a connecting shaft 103 perpendicular to the horizontal plane, a bottom of the connecting shaft 103 is provided with a concave connecting seat 104, an outer wall of the connecting seat 104 is provided with a paddle 105, a vertical plate 106 is arranged on the top of each skateboard 601, and an elastic paddle 107 for contacting the paddle 105 is arranged on one side of each vertical plate 106.

[0053] The rotating device 102 drives the connecting shaft 103 to drive the connecting seat 104 to rotate, so that the paddle 105 rotates synchronously. When the paddle 105 contacts the elastic paddle 107, the paddle 105 squeezes the elastic paddle 107 to drive the slide plate 601 to move, and squeezes the elastic paddle 107 to cause elastic deformation. When the paddle 105 passes over the elastic paddle 107 and loses contact with the elastic paddle 107, the slide plate 601 vibrates under the elastic force of the first spring 603.

[0054] In this embodiment, the rotating device 3 and the rotating device 102 are both existing technologies, for example, they can be motors, etc.
