Description

Technical Field

[0001] The present invention relates to the technical field of soldering machines, and particularly to a soldering machine for laser tube pin terminals. Background Art

[0002] A soldering machine is an automated device used for soldering electronic components, metal parts, etc. It mainly melts the solder through a heating device and then precisely conveys the melted solder to the parts that need to be soldered, replacing the traditional manual soldering method. The soldering machine has a high degree of precision, can accurately control the amount of solder used and the soldering position, ensuring the consistency and reliability of the solder joint quality. Many soldering machines are also equipped with various functions such as temperature control and solder feeding speed adjustment, and can flexibly adjust parameters according to different soldering materials and process requirements to ensure the stability of the soldering process and the optimization of the soldering effect. During the soldering process between the pins of the laser tube and the chip, a soldering machine is often required.

[0003] A soldering machine with the publication number of CN110355436B includes a frame, a soldering head, and a tin wire positioning tube. A first guide seat is fixedly arranged on the frame. A first sliding seat is arranged on the first guide seat, and the first sliding seat is slidably matched with the first guide seat along the X-axis. A second guide seat is fixedly arranged on the first sliding seat. A second sliding seat is arranged on the second guide seat, and the second sliding seat is slidably matched with the second guide seat along the Y-axis. The soldering head slides synchronously with the second sliding seat along the Y-axis. The frame is provided with a first driving mechanism for driving the first sliding seat to slide and a second driving mechanism for driving the second sliding seat to slide.

The soldering machine of the present invention can adjust the soldering head and perform soldering on circuit boards of different specifications.

[0004] The existing related technologies often have the following defects: During the soldering process between the pins of the laser tube and the chip, after soldering is completed, the solder is often in a high-temperature molten state. Although it will gradually solidify after stopping laser heating, if the surrounding environmental temperature is high or the heat cannot be dissipated in time, the solder may be deformed due to the residual heat, and it is not easy for the product to enter the next process for quality inspection or assembly link more quickly, thus reducing the soldering efficiency between the pins of the laser tube and the chip.

[0005] Therefore, we propose a soldering machine for laser tube pin terminals. Summary of the Invention

[0011] The effects achieved by the above components are as follows: By setting up an air-cooling structure, it not only facilitates the pre-treatment and cleaning of the dust on the pins and chip surfaces of the row of laser tubes to be processed, but also during the processing of the pins and chips of the laser tubes, it conducts real-time air-cooling work on the pins and chips of the row of laser tubes after welding. Blowing air can accelerate the dissipation of heat, improve the solidification efficiency of the solder, help shorten the cycle of the entire welding process, improve production efficiency, and timely cooling helps prevent solder deformation and internal stress generation. Blowing air can evenly cool the solder, avoid irregular solder shapes caused by local overheating, and uniform cooling can reduce internal stress and lower the risk of microcracks appearing at the solder joints, thereby enhancing the mechanical strength and electrical performance of the solder joints, ensuring the stability and reliability of the connection of the laser tube pin terminals.

By setting up a smearing structure, it facilitates the flexible smearing work of the flux on the welding positions of the pins and chips of the row of laser tubes, and improves the welding efficiency of the pins and chips of the laser tubes to a certain extent. By setting up an auxiliary structure, it facilitates the smearing work of the flux after rough treatment of the surface of the solder wire, and further improves the welding efficiency of the pins and chips of the laser tubes.

[0012] Preferably, a limiting frame is slidably connected inside the pressing plate, and the lower end of the limiting frame is fixedly connected to the bottom plate.

[0013] The effects achieved by the above components are as follows: By setting the limiting frame to slide inside the pressing plate, it plays a role in restricting the moving direction between the pressing plate and the bottom plate, and further restricts the telescopic direction of the folding cylinder.

[0014] Preferably, a rubber cylinder is adhesively connected to the side wall of the rotating wheel.

[0016] Preferably, the widths of several of the air holes become smaller from the middle to both sides.

[0017] The effects achieved by the above components are as follows: Since there are rows of air holes opened on the air plate, and the two parts of the air holes are respectively located on both sides of the welding head, one side of the air holes can achieve timely air-cooling and temperature reduction work on the positions of the pins and chips of the laser tube after welding.

[0018] Preferably, the smearing structure further includes a positioning strip fixedly connected inside the storage tank, a limiting strip is slidably connected inside the positioning strip, and a piston is fixedly connected to the lower end of the limiting strip.

[0019] The effect achieved by the above components is: when the piston is lifted, the flux will flow into the circular tube along the storage tank, and finally flow into the inner side of the hollow plate and out from the drip hole position, and the outflowing flux will wet the bristles along the drip hole.

[0020] Preferably, the outer diameter of the piston is matched with the inner diameter of the circular tube.

[0021] The effect achieved by the above components is: the pressure plate is at the lowest position, at which time the piston can seal the upper port position of the circular tube and stop applying the flux.

[0022] Preferably, a reserved block is fixedly connected to the upper end of the limiting strip, and the reserved block is fixedly connected to the side wall of the pressing plate.

[0023] The effect achieved by the above components is that when the pressure plate moves up and down repeatedly, the pressure plate will simultaneously drive the limit strip on the reserved block to slide inside the positioning strip, and at this time the piston can be driven up and down.

[0024] Preferably, both ends of the rotating drum are truncated cone-shaped structures, a plurality of rows of the scraping thorns are arranged in an arc on the inner side of the rotating drum, and the tin wire is located on the inner side of the rotating drum.

[0025] The effect achieved by the above components is: by setting the upper and lower ports as ports with a truncated cone structure, not only the resistance of the drum port position to the tin wire during feeding is avoided, but also the insertion and feeding of the tin wire from the inside of the drum is facilitated.

[0026] Preferably, a collecting frame is fixedly connected to the side wall of the mounting tube, and a bottom side of the collecting frame is a slope structure.

[0027] The above components achieve the following effects: in the process of roughening the surface of the tin wire, the tin scraps shoveled out will fall into the inner side of the collection frame, which facilitates the centralized processing of the tin scraps.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. By setting up an air-cooling structure, the present invention not only facilitates the pre-treatment cleaning work on the pins and chip surfaces of rows of laser tubes to be processed, but also during the processing of the pins and chips of the laser tubes, it conducts real-time air-cooling work on the pins and chips of the rows of laser tubes after welding. Blowing air can accelerate the dissipation of heat, improve the solidification efficiency of the solder, help shorten the cycle of the entire welding process, improve production efficiency, and timely cooling helps prevent solder deformation and the generation of internal stress. Blowing air can evenly cool the solder, avoid irregular solder shapes caused by local overheating, and uniform cooling can reduce internal stress and lower the risk of microcracks appearing at the solder joints, thereby enhancing the mechanical strength and electrical performance of the solder joints, ensuring the stability and reliability of the connection of the laser tube pin terminals. Blowing air for cooling can also reduce the possibility of scalding operators caused by excessive temperature of the equipment shell, thus improving the performance of the soldering machine to a certain extent.

[0032] 2. By setting up a smearing structure, a certain amount of flux is added inside the storage tank. During the process of starting the moving seat to solder the pins and chips of the rows of laser tubes, when the pressing plate moves up and down repeatedly, the pressing plate will drive the limiting strip on the reserved block to slide inside the positioning strip. At this time, the up and down driving work of the piston can be realized. When the piston lifts, the flux will flow into the circular tube along the storage tank and finally flow out from the drip holes on the inner side of the hollow plate. The flowing flux will wet the bristles along the drip holes. During the movement of the hollow plate, relative movement occurs between the hollow plate and the pins and chips of the rows of laser tubes, thus realizing the smearing work on the welding positions of the pins and chips of the rows of laser tubes. By setting up the smearing structure, it facilitates the flexible smearing work of the flux on the welding positions of the pins and chips of the rows of laser tubes, and improves the welding efficiency of the pins and chips of the laser tubes to a certain extent.

[0033] 3. By setting up an auxiliary structure, during the process of the solder wire being conveyed inside the rotating cylinder, the installation cylinder, the first transmission tube, the fixed cylinder, and the second transmission tube, the scraping thorns can realize the pre-treatment work on the surface of the solder wire. Through the treatment of the surface of the solder wire with scraping thorns, the surface of the treated solder wire is relatively rough. When the solder wire is transmitted to the position of the fixed cylinder, since part of the flux will flow into the inner side of the fixed cylinder along the hose, the flux inside the fixed cylinder can realize the smearing work on the surface of the solder wire, further improving the treatment effect on the surface of the solder wire. Through the treatment of the rough surface of the solder wire, the effect of the flux adhering to the surface of the solder wire is further improved. By setting up the auxiliary structure, it facilitates the smearing work of the flux after the surface of the solder wire is roughened, and further improves the welding efficiency of the pins and chips of the laser tubes in the subsequent process.

It further includes: an air-cooling structure 7 arranged on the side wall of the support frame 2. The air-cooling structure 7 includes a bottom plate 706 fixedly connected to the side wall of the moving seat 3.

A guide rail frame 702 is fixedly connected to the side wall of the support frame 2. A reserved groove 705 is opened on the surface of the guide rail frame 702. The middle side of the reserved groove 705 is a groove hole with a wavy line structure, and the two end sides are notch openings with a straight line structure. A runner 710 is rotatably installed at the end side of the support rod 709. The runner 710 is located inside the reserved groove 705; a smearing structure 8 arranged inside the bottom plate 706. The smearing structure 8 includes a storage tank 82 fixedly connected to the inside of the bottom plate 706. A circular pipe 81 is fixedly and communicatively connected to the lower port of the storage tank 82. The lower port of the circular pipe 81 is fixedly and communicatively connected to a hollow plate 87. The hollow plate 87 is fixedly connected to the lower surface of the wind plate 704. The hollow plate 87 is of a hollow structure. A plurality of dripping holes 88 are evenly opened on the lower surface of the hollow plate 87. A plurality of brush hairs 89 are evenly fixedly connected to the lower surface of the hollow plate 87; an auxiliary structure 9 arranged on the side wall of the fixed seat 10. The auxiliary structure 9 includes an auxiliary plate 93 fixedly connected to the side wall of the fixed seat 10. A limiting ring 94 is fixedly installed on the other side of the auxiliary plate 93. A rotating cylinder 96 is rotatably installed inside the limiting ring 94. A plurality of columns of barbs 97 are evenly fixedly connected to the inside of the rotating cylinder 96. The barbs 97 are of a barbed structure. A hose 91 is communicatively and fixedly connected between the fixed cylinder 13 and the storage tank 82.By setting up the air-cooling structure 7, not only is it convenient to pre-treat and clean the dust on the pins and chip surfaces of the row of laser tubes to be processed, but also during the processing of the pins and chips of the laser tubes, real-time air-cooling work is carried out on the pins and chips of the row of laser tubes after welding. By blowing air, the heat dissipation can be accelerated, the solidification efficiency of the solder can be improved, which helps to shorten the cycle of the entire welding process, improve the production efficiency. Timely cooling helps to prevent the deformation of the solder and the generation of internal stress. Blowing air can make the solder cool evenly, avoiding the irregular shape of the solder caused by local overheating. And uniform cooling can reduce the internal stress and lower the risk of micro-cracks appearing at the solder joints, thereby enhancing the mechanical strength and electrical performance of the solder joints, ensuring the stability and reliability of the connection of the laser tube pin terminals. Blowing air for cooling can also reduce the possibility of scalding the operator caused by the over-high temperature of the equipment shell, thus improving the performance of the soldering machine to a certain extent. By setting up the smearing structure 8, it is convenient for the flexible smearing of the soldering flux on the welding positions of the pins and chips of the row of laser tubes, improving the welding efficiency of the pins and chips of the laser tubes to a certain extent. By setting up the auxiliary structure 9, it is convenient for the smearing of the soldering flux after the surface of the solder wire 15 is roughened, further improving the welding efficiency of the pins and chips of the laser tubes in the follow-up.

[0048] Next, specifically describe the specific settings and functions of its extrusion structure 3, auxiliary structure 4 and limiting structure 5.

[0049] As Figures 1-7 shown, a limiting frame 707 is slidably connected inside the pressing plate 708, and the lower end of the limiting frame 707 is fixedly connected to the bottom plate 706. By setting the limiting frame 707 to slide inside the pressing plate 708, it plays a role in restricting the moving direction between the pressing plate 708 and the bottom plate 706, and further restricts the telescopic direction of the folding cylinder 703. A rubber cylinder 711 is adhesively bonded to the side wall of the runner 710. The setting of the rubber cylinder 711 effectively improves the stability of the runner 710 during rotation. The widths of a number of air holes 712 gradually decrease from the middle to both sides. Since the air holes 712 are arranged in rows on the air plate 704, the two parts of the air holes 712 are respectively located on both sides of the welding head 6, and one side of the air holes 712 can achieve timely air-cooling and temperature reduction of the positions of the pins and chips of the laser tube after welding.

[0050] As Figures 1-3 and Figures 5-8As shown, the coating structure 8 also includes a positioning strip 83 fixedly connected to the inner side of the storage tank 82, and the internal sliding connection of the positioning strip 83 is a limiting strip 84, and the lower end of the limiting strip 84 is fixedly connected to a piston 86. When the piston 86 is lifted, the flux will flow into the circular tube 81 along the storage tank 82, and finally flow into the inner side of the hollow plate 87 and flow out from the drip hole 88. The outflowing flux will wet the bristles 89 along the drip hole 88. The outer diameter of the piston 86 is compatible with the inner diameter of the circular tube 81. The pressing plate 708 is in the lowest position, at which time the piston 86 can achieve the blocking work of the upper port position of the circular tube 81, and the coating work of the flux can be stopped. The upper end of the limiting strip 84 is fixedly connected to a reserved block 85, and the reserved block 85 is fixedly connected to the side wall of the pressing plate 708. When the pressing plate 708 repeatedly moves up and down, the pressing plate 708 will simultaneously drive the limiting strip 84 on the reserved block 85 to slide inside the positioning strip 83, and at this time, the piston 86 can be driven up and down.

[0051] like Figures 1-2 and Figures 4-5 as well as Figures 9-11 As shown, both ends of the rotating drum 96 are truncated cone-shaped structures, and a plurality of rows of scraping thorns 97 are arranged in an arc on the inner side of the rotating drum 96, and the tin wire 15 is located on the inner side of the rotating drum 96. By setting the upper and lower ends as truncated cone-shaped ports, not only the resistance of the rotating drum 96 port position to the tin wire 15 when feeding is avoided, but also the insertion and feeding of the tin wire 15 from the inner side of the rotating drum 96 is facilitated. The side wall of the mounting cylinder 14 is fixedly connected with a collecting frame 92, and a bottom side of the collecting frame 92 is an inclined surface structure. In the process of roughening the surface of the tin wire 15, the tin scraps shoveled out will fall into the inner side of the collecting frame 92, which is convenient for the centralized processing of the tin scraps. A collecting trough 95 is slidably installed on the inner side of the collecting frame 92. The accumulated tin scraps will flow into the inner side of the collecting trough 95 along the inclined surface on the inner side of the collecting frame 92, and the collecting trough 95 can be drawn out from the inner side of the collecting frame 92, which is convenient for the reuse of the collected tin scraps.

[0052] Working principle: During the welding process between the pins and chips of an array of laser tubes, when driving the moving seat 3 to move, after the runner 710 moves along the strip-shaped groove position of the reserved groove 705 to the inner side of the wavy line, the rotating rod will move up and down inside the reserved groove 705 of the wavy line structure, so as to realize the simultaneous up and down driving of the support rod 709 and the pressing plate 708. The setting of the runner 710 avoids the relative movement between the support rod 709 and the inner side of the wavy line groove reserved groove 705, resulting in the phenomenon of serious wear of the support rod 709. The setting of the rubber cylinder 711 effectively improves the stability of the runner 710 during driving rotation. During the up and down movement of the pressing plate 708 inside the wavy line groove opening, the pressing plate 708 will move up and down, so as to realize the flexible compression and extension of the folding cylinder 703 between the pressing plate 708 and the bottom plate 706. When the folding cylinder 703 is compressed, the compressed gas will flow into the inner side of the air plate 704 along the connecting pipe 701 and finally spray out along the air holes 712, thus realizing the air-cooling and temperature reduction of the positions of the pins and chips of the laser tube after welding. Since there are rows of air holes 712 on the air plate 704, the two parts of the air holes 712 are respectively located on both sides of the welding head 6. One side of the air holes 712 can realize the timely air-cooling and temperature reduction of the positions of the pins and chips of the laser tube after welding, and the other side of the air holes 712 can realize the blowing of dust on the chips and pins on the circuit board as much as possible, improving the soldering quality between the pins and chips of the laser tube. When the pressing plate 708 passes from the inner side of the wavy line structure reserved groove 705 to the inner side of the strip-shaped groove, the folding cylinder 703 is always in a compressed state, and the air-cooling work on the positions of the pins and chips of the laser tube can be stopped. By setting the limit frame 707 to slide inside the pressing plate 708, it plays a role in restricting the moving direction between the pressing plate 708 and the bottom plate 706, and further restricts the telescopic direction of the folding cylinder 703, avoiding the phenomenon of the folding cylinder 703 being tilted, and further improving the compression effect of the folding cylinder 703. The air holes 712 arranged in rows and gradually decreasing in size from the middle to both sides are because the positions of the pins and chips of the laser tube after initial processing are relatively hot and require uniform and relatively large-area wind force for uniform temperature reduction. Therefore, larger air holes 712 are arranged as close as possible to the welding head 6. By setting the air-cooling structure 7, it not only realizes the convenient pre-treatment cleaning of the surface dust of the pins and chips of the array of laser tubes to be processed, but also realizes the real-time air-cooling work on the pins and chips of the array of laser tubes during the processing of the pins and chips of the laser tube. By blowing, the heat dissipation can be accelerated, the solidification efficiency of the solder can be improved, which helps to shorten the cycle of the whole welding process and improve the production efficiency. Timely cooling helps to prevent the deformation of the solder and the generation of internal stress. Blowing can make the solder cool evenly, avoid the irregular shape of the solder caused by local overheating, and uniform cooling can reduce the internal stress and the risk of micro-cracks in the solder joints, thereby enhancing the mechanical strength and electrical performance of the solder joints.Ensure the stability and reliability of the connection of the laser tube pin terminals. The blowing cooling can also reduce the possibility of scalding the operator caused by the over-high temperature of the equipment shell, thus improving the performance of the soldering machine to a certain extent.

[0053] Add a certain amount of flux inside the storage tank 82. During the process of starting the moving seat 3 to solder the pins and chips of the row of laser tubes, when the pressing plate 708 moves up and down repeatedly, the pressing plate 708 will drive the limiting strip 84 on the reserved block 85 to slide inside the positioning strip 83. At this time, the up and down driving of the piston 86 can be realized. When the piston 86 is lifted, the flux will flow into the circular tube 81 along the storage tank 82 and finally flow into the inside of the hollow plate 87 and flow out from the drip hole 88. The flowing flux will wet the brush hair 89 along the drip hole 88. During the movement of the hollow plate 87, relative movement will occur between the hollow plate 87 and the pins and chips of the row of laser tubes, thus realizing the smearing work on the welding positions of the pins and chips of the row of laser tubes, further improving the subsequent welding efficiency between the pins and chips of the row of laser tubes. Similarly, when the runner 710 moves to the inside of the strip-shaped groove of the reserved groove 705, the pressing plate 708 is in the lowest position. At this time, the piston 86 can block the upper port position of the circular tube 81 to stop the smearing work of the flux, thus improving the flexibility of the use of the flux and avoiding waste during the use of the flux. By setting the smearing structure 8, it is convenient to smear the flux flexibly on the welding positions of the pins and chips of the row of laser tubes, and the subsequent welding efficiency of the pins and chips of the laser tubes is improved to a certain extent.

[0054] In the process of conveying the tin wire 15 on the inner side of the rotating drum 96, the mounting drum 14, the first transmission tube 11, the fixed drum 13 and the second transmission tube 12, the scraper 97 can realize the pretreatment of the surface of the tin wire 15. By using the scraper 97 to treat the surface of the tin wire 15, the surface of the treated tin wire 15 is relatively rough. When the tin wire 15 is transmitted to the position of the fixed drum 13, part of the flux will flow into the inner side of the fixed drum 13 along the hose 91. At this time, the flux on the inner side of the fixed drum 13 can realize the smearing work on the surface of the tin wire 15, which further improves the treatment effect of the surface of the tin wire 15. By treating the rough surface of the tin wire 15, the effect of the flux adhering to the surface of the tin wire 15 is further improved. By setting the barbs arranged in an arc shape, when the rotating drum 96 twists on the inner side of the limit ring 94 during the feeding of the tin wire 15, the arc shape of the surface of the tin wire 15 can be realized. The scraping work of the structural lines increases the processing length of the rough position on the surface of the tin wire 15, and further improves the subsequent coating effect of the flux on the surface of the tin wire 15. By setting the upper and lower ports as ports of a truncated cone structure, not only the resistance of the port position of the rotating drum 96 when feeding the tin wire 15 is avoided, but also the insertion and feeding of the tin wire 15 from the inner side of the rotating drum 96 is facilitated. In the process of roughening the surface of the tin wire 15, the shoveled tin chips will fall into the inner side of the collecting frame 92, which is convenient for the centralized processing of the tin chips. The accumulated tin chips will flow into the inner side of the collecting trough 95 along the inclined surface on the inner side of the collecting frame 92. The collecting trough 95 can be drawn out from the inner side of the collecting frame 92, which is convenient for the reuse of the collected tin chips. By setting the auxiliary structure 9, the coating of the flux after the roughening treatment of the surface of the tin wire 15 is facilitated, and the subsequent welding efficiency of the pins and chips of the laser tube is further improved.
