Description

Technical Field

[0001] The present invention belongs to the technical field of welding equipment, and particularly relates to a semiconductor welding equipment with a flux recovery function. Background Art

[0002] Flux: A chemical substance that can assist and promote the welding process in the welding technology, and at the same time has a protective effect and prevents oxidation reactions. Flux can be divided into solid, liquid and gas. It mainly has several aspects such as "assisting heat conduction", "removing oxides", "reducing the surface tension of the welded material", "removing the surface oil stain of the welded material and increasing the welding area", "preventing re-oxidation", etc. Among these aspects, two relatively key functions are: "removing oxides" and "reducing the surface tension of the welded material".

[0003] The flux recovery methods mainly include physical method, chemical method and biological method. During the semiconductor welding process, since a large amount of flux is added to the solder paste, the volatilized flux becomes fine particles after air cooling, and the residues of the flux will accumulate more and more in the pipeline, which will affect the normal gas transportation function in the pipeline. At the same time, when the residual flux is not recovered in time, it will also cause secondary pollution to the welded products. The residual flux adheres to the surface of the welded parts, and these residues will absorb dust and moisture in the air, generating a moisture layer on the surface of the circuit board, thereby reducing the insulation resistance of the circuit board surface and causing corrosion or metal dendrites on the circuit board. When the dendrites bridge between the circuits or solder joints, it will cause a short circuit situation, greatly affecting the product quality. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Refer to the attached drawings of the specification Figure 1 and the attached drawings Figure 2 As shown, a semiconductor welding device with a flux recovery function includes: a welding mechanism 1. The welding mechanism 1 includes a cylinder 2 fixed on a frame. The piston rod on the cylinder 2 penetrates through the frame and is connected to a cross beam 3. Both extending sections on both sides of the cross beam 3 are connected to a welder 4, and an inclined welding head is connected to the welder 4. The conical opening on the ventilation duct 6 can effectively expand the contact surface of the flux gas, and can effectively introduce the flux gas into the ventilation duct 6. During the flow of the flux gas, it becomes fine particles after being cooled by air and even adheres to the filter plate 10. Substantially, a protruding end is provided at the top of the ventilation duct 6, and an activity cavity is formed in the protruding end, so as to facilitate the free up and down movement of the filter plate 10 itself, thereby avoiding affecting the normal movement of the transmission parts.

[0021] The welding mechanism 1 is provided. After the cylinder 2 is started, it can drive the welders 4 at both ends of the cross beam 3 to perform welding work between the semiconductor and the edge of the welded part. The cross beam 3 acts as a synchronous medium, enabling the welders 4 to perform welding work synchronously, ensuring welding accuracy and improving product quality.

[0022] The first filtering and recycling mechanism 5, the first filtering and recycling mechanism 5 includes a ventilation duct 6 placed directly above the welding head. One end of the ventilation duct 6 is installed with a Y-shaped pipe 7 adapted to it. The upward extension of the Y-shaped pipe 7 is fixedly connected with an exhaust fan 8. On both sides of the top end inner wall of the ventilation duct 6, a filter plate 10 is connected through a telescopic rod 9. Along the height direction of the ventilation duct 6, a guide groove is connected to the outer wall of the filter plate 10, and filter holes 11 are provided on the filter plate 10; Among them, the filter plates 10 are connected with a driving component 13 through a moving plate 12. The driving component 13 includes a servo motor 14 fixed at the center of the side plate. One end of the output shaft of the servo motor 14 extends to the center gear 15 and the turntable 16 in sequence. Both ends of the center gear 15 are meshed and driven with gear plates 17 moving in opposite directions. One end of the gear plate 17 is connected to a scraper 18 on the outer wall of the filter plate 10 through a first bracket. The protruding part on the turntable 16 and the slider 19 are connected through a swing rod 20. Along the height direction of the side plate, a chute is connected to the outer wall of the slider 19, and both ends of the slider 19 are connected to the filter plate 10 through a second bracket.

[0023] Reference Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , both sides of the swing rod 20 are installed on the protruding part and the slider 19 through a rotational connection. Positioning blocks 21 connected to the first bracket and the second bracket are respectively provided at the upper and lower ends of the filter plate 10. A first collection box 22 with a notch is placed on the ventilation duct 6 directly below the filter plate 10. The first collection box 22 is designed as a movable pull-out type.

[0024] The side plate is fixedly connected to the inner wall of the ventilation duct 6, and the slider 19 is movably connected to the side plate. At the same time, the servo motor 14 is fixed on the side plate. In this way, when the driving component 13 is started, and during the rotation of the turntable 16, through the rotational connection function of the swing rod 20, the rotational power of the turntable 16 can be converted into the linear up and down movement of the slider 19 in the chute. Moreover, during the movement of the slider 19, the filter plates 10 at both ends can be driven to move up and down through the second bracket. In this way, during the up and down shaking of the filter plates 10, the adsorbed flux particles can be effectively separated, and then corresponding collection and treatment can be carried out in the first collection box 22. At the same time, the first collection box 22 is designed as a movable pull-out type, which effectively facilitates the operation of personnel and improves work efficiency.

[0025] In addition, the movable plate 12 is arranged between the filter plates 10. On the one hand, it can connect the filter plates 10 at both ends. On the other hand, it can achieve a corresponding synchronous effect on the movement of the two, thus ensuring the stability of the device during operation. Moreover, the telescopic rods 9 on the filter plates 10 and the sliders 19 on the side plates can both support and connect the filter plates 10, preventing the situation of overloading the filter plates 10 by a single support member and affecting the safety of the device during use. After the servo motor 14 is started, it can also drive the scraper 18 on the first bracket to clean the filter plates 10 through the gear plate 17, effectively preventing the filter holes 11 from being blocked and ensuring the filtering quality of the filter plates 10.

[0026] At the same time, the chute on the side plate can prevent the sliders 19 from deviating in position during movement. The forward and reverse movement of the servo motor 14 can drive the synchronous rotation of the turntable 16. In this way, during the forward and reverse movement of the turntable 16, it can not only ensure the normal up and down movement of the filter plates 10, but also enable the scraper 18 to perform corresponding cleaning work on the filter plates 10 during the process of moving and fitting in contact with the filter plates 10.

[0027] The first filter recovery mechanism 5 is provided. The gas residues generated during the welding process will be introduced into the ventilation duct 6 under the action of the exhaust fan 8. The flux becomes fine particles after air cooling and is blocked by the filter plates 10. At this time, the drive assembly 13 is started, and the servo motor 14 drives the simultaneous rotation of the central rotating gear 15 and the turntable 16. Under the meshing transmission of the gears, the central rotating gear 15 can drive the scrapers 18 at both ends of the gear plate 17 to move up and down, thus cleaning the front end of the filter plates 10 by moving, effectively preventing the filter holes 11 on the filter plates 10 from being blocked and affecting the filtering quality of the filter plates 10. At the same time, during the rotation of the turntable 16, with the rotational connection of the swing rod 20, it can drive the entire filter plates 10 to move up and down on the telescopic rods 9. Through the process of up and down shaking, the particulate matter blocked on the filter plates 10 can be shaken off into the first collection box 22, realizing the recovery of the flux, reducing resource waste, and saving raw materials and costs.

[0028] Reference Figure 1 、 Figure 7 and Figure 8 The top of the first collection box 22 is provided with a material dropping port placed on the ventilation duct 6. The connection between the movable plate 12 and the filter plates 10 is provided with positioning holes and is connected by means of being locked and fixed by bolt assemblies. The top end of the ventilation duct 6 is integrally formed and connected with a movable cavity connected to the filter plates 10.

[0029] The semiconductor welding equipment with a flux recovery function further includes a second filtration and recovery mechanism 23 disposed at one end in the horizontal direction of the Y-shaped tube 7. The second filtration and recovery mechanism 23 includes a box body 24 filled with water. A partition plate 25 is integrally formed and connected to the inner wall of the box body 24. An inclined plate 26 is provided below the feed inlet on the box body 24. One end of the inclined plate 26 is in contact and fit with a support plate 27. The support plate 27 is detachably installed on the first conveyor belt 28. The upper and lower ends of the first conveyor belt 28 are correspondingly connected to a first rotating wheel 29 and a second rotating wheel 30 in a driving manner.

[0030] One end of the second rotating wheel 30 is connected to a rotating and guiding assembly 31 disposed between the partition plate 25 and the inclined plate 26. The rotating and guiding assembly 31 includes a first rotating shaft 32 movably connected to the side wall of the box body 24. An annular array of baffle plates 33 is installed on the outer wall of the first rotating shaft 32. And a first rotating gear 34 is fixed on the outer wall of the first rotating shaft 32. A second rotating gear 36 fixed on a second rotating shaft 35 is meshed and driven on the outer wall of the first rotating gear 34. A second conveyor belt 37 is connected between the second rotating shaft 35 and the second rotating wheel 30 in a driving manner. And one end of the support plate 27 is in contact and fit with a guide plate 38 on the inner wall of the box body 24.

[0031] By setting the second filtration and recovery mechanism 23, the exhaust fan 8 on the Y-shaped tube 7 can, on the one hand, discharge the cleaned gas, and discharge the particulate matter into the box body 24 by using the self-gravity of the particulate matter. The flux particulate matter precipitates in the water body and falls onto the inclined plate 26, and slides down the inclined plate 26 to the support plate 27 on the first conveyor belt 28. The particulate matter can drive the rotation of the baffle plate 33 during the sliding process. During the rotation of the baffle plate 33, the first rotating gear 34 on the first rotating shaft 32 is driven to rotate. Under the meshing and driving action of the gears and in cooperation with the driving action of the conveyor belt, the first conveyor belt 28 can rotate in a cycle, and the particulate matter is conveyed to the second collection box 39 through the guide plate 38. Thus, the automatic collection work is completed during the precipitation process of the particulate matter in the water body. The setting of the water body can precipitate and aggregate the particulate matter and complete the collection work at the same time. Moreover, the rotating and guiding assembly 31 converts the driving force of the particulate matter sliding into the rotating force of the conveyor belt, with strong automation performance, no need to set an additional power source, energy-saving and environmental protection, and can play a role in secondary recovery of the flux.

[0032] A second collection box 39 fixed to the outer wall of the box body 24 is provided below the guide plate 38. The vertical center lines of the second rotating wheel 30 and the first rotating wheel 29 are both on the same axis. The baffle plate 33 and the second conveyor belt 37 are arranged in a parallel and staggered manner. An arc-shaped groove 40 disposed at the bottom of the partition plate 25 is provided at the outer wall edge of the baffle plate 33. A guiding cavity is jointly formed among the baffle plate 33, the inclined plate 26 and the inner wall of the box body 24. As the baffle plate 33 rotates, the second conveyor belt 37 drives the support plate 27 to rotate in the opposite direction to the baffle plate 33, and conveys the recovered particles to the guide plate 38.

[0033] Specifically, when the driving force of the first conveyor belt 28 on the first rotating wheel 29 and the second rotating wheel 30 is insufficient, a driving motor can also be provided on the corresponding rotating wheel. In this way, under the driving action of the driving motor, the first conveyor belt 28 can maintain normal driving force, and at the same time, the power can be transmitted to the second rotating shaft 35. Under the transmission action of gear meshing, the first rotating shaft 32 on the first rotating tooth 34 can be kept rotating in the reverse direction, and the baffle 33 is driven to remove the flux particles that precipitate and accumulate onto the support plate 27, so as to avoid the situation that the slipping flux particles cannot ensure the normal power transmission work of the conveyor belt.

[0034] In addition, the partition plate 25 on the inner wall of the box body 24 can not only separate the support plate 27 and the inclined plate 26, but also the arc-shaped groove 40 at the bottom of the partition plate 25 can enable the annularly arranged baffles 33 to maintain normal rotation, preventing the baffles 33 from interfering with the partition plate 25 during the movement. At the same time, one end of the inclined plate 26 close to the support plate 27 is arranged as a vertical surface, so that when the inclined plate 26 contacts and fits on the support plate 27, the flux particles can be introduced onto the support plate 27 and enter the second collection box 39 through the action of rotary conveying.

[0035] The four sides of the bottom of the frame are all connected to the ground through columns, and a bearing platform is provided on the frame between the welding heads. A support column is provided at the bottom of the ventilation duct 6 on the frame, and a conical opening is provided at one end of the ventilation duct 6 directly above the bearing platform. The bearing platform is mainly used to place semiconductors and welding parts, and the support column on the ventilation duct 6 can provide corresponding support force for it. An arc-shaped plate in contact connection with the bottom surface of the ventilation duct 6 can also be added at the top of the support column according to actual needs. In this way, the applied force can be dispersed by expanding the contact surface, improving the connection stability.
