Description

Technical Field

[0001] This utility model relates to the field of tinning machine technology, and more specifically, to a tin scraping device for a double-head tinning machine. Background Technology

[0002] A double-head tinning machine is an automated device used for wire processing. It is mainly used to simultaneously complete processes such as wire cutting, stripping, twisting, and tinning at both ends. It can efficiently process electronic wires, sheathed wires, and other wires, achieving synchronous tinning at both ends. It is suitable for wire harness processing, electronic manufacturing, and other fields. A tin scraper is a device used to clean the oxide layer of tin dross generated in the tin furnace. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of tin scrapers.

[0003] Existing solder scraping devices have certain drawbacks. First, they cannot collect the scraped solder dross oxide layer, making it difficult for workers to clean. Second, they cannot adjust the height of the flux tank, which means that short wire openings cannot be immersed in flux, thus preventing soldering and making it inconvenient to use. Furthermore, when the soldering machine vibrates, the molten solder inside the solder pot shakes, causing it to overflow and wasting resources. It may also result in uneven soldering of the wire openings, affecting the soldering quality.

[0004] A search revealed that Chinese patent CN209175085U discloses a tin scraping device for an automatic tinning machine. The device uses a tin dross collection tank to collect the oxide layer of tin dross scraped out of the tin furnace by the tin scraping robot. The operator can remove the tin dross collection tank from the L-shaped connector through the installation slot and then clean the oxide layer of tin dross inside, which is convenient for users.

[0005] In actual use, the tin scraping device of the above-mentioned automatic tin dipping machine usually uses a single scraper to scrape off the oxidized molten tin on the surface. It can only scrape off large oxide layers on the surface of the molten tin, and it is not convenient to clean small particles. This will result in incomplete removal of oxide layers and impurities, which will lead to soldering defects. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a solder scraping device for a double-head soldering machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A tin scraping device for a double-head tin dipping machine includes a base, a tin furnace fixedly connected to the top of the base, tin dross collection tanks fixedly connected to both sides of the tin furnace, a protective shell fixedly connected to the top of the base, a connecting shell fixedly connected to one side of the protective shell, a drain pipe connected to one side of the connecting shell, and a scraping component provided on the connecting shell. The scraping assembly includes an electric push rod, which is installed inside the protective housing. A fixing plate is fixedly connected to the output end of the electric push rod. The fixing plate is slidably connected to the inner side of the connecting housing and to the inner side of the tin pot. A first scraper is fixedly connected to the bottom end of the fixing plate. The first scraper has a tapered cross-section. The connecting shell is provided with a cleaning mechanism. Two arc-shaped plates are fixedly connected to the fixing plate. The arc-shaped plates are circular arcs and are staggered at the bottom of the fixing plate. A second scraper is fixedly connected to the fixing plate. An inclined groove is provided on one side of the second scraper. The inclined groove is V-shaped.

[0008] By adopting the above technical solution, a multi-stage scraping effect on the surface of molten solder can be achieved, thereby improving the cleaning effect on the surface of molten solder.

[0009] As a further description of the above technical solution: the cleaning structure includes a stepper motor, which is installed on one side of the connecting housing. A lead screw is fixedly connected to the output end of the stepper motor. The lead screw is rotatably connected to the inside of the connecting housing. A threaded plate is threaded to the outside of the lead screw. A cavity is opened on the inner side of the threaded plate. The cavity is adapted to the outer side of the fixed plate. The threaded plate is slidably connected to the outer side of the fixed plate. A brush plate is fixedly connected to the inner side of the threaded plate. A diverter pipe is provided inside the threaded plate. Multiple nozzles are connected to one side of the diverter pipe. The nozzles are inclined on one side of the threaded plate. A water pump is installed at the top of the base. Both the output and input ends of the water pump are connected to connecting hoses. One end of one of the connecting hoses extends to the inner side of the threaded plate and is connected to one side of the diverter pipe.

[0010] By adopting the above technical solution, the surfaces of the first scraper, the arc plate, and the second scraper can be cleaned in time after the molten solder is scraped off, thereby reducing the adhesion of molten solder.

[0011] The technical effects and advantages of this utility model are as follows: 1. By setting up a scraping component, compared with the existing technology, the second scraper can quickly scrape across the surface of the molten solder to remove large oxide layers and impurities. The arc plate can further clean up residual tiny oxide particles and impurities. Finally, the first scraper flattens the surface of the molten solder, thereby achieving multi-stage scraping, which helps to improve the cleaning effect on the surface of the molten solder and thus ensures long-term stable soldering quality. 2. By setting up a cleaning mechanism, compared with the existing technology, the threaded plate is adapted to the outside of the fixed plate, so that the threaded plate can drive the brush plate and multiple nozzles to clean the first scraper, arc plate and second scraper at the bottom of the fixed plate. After scraping, the residual solder can be removed in time, thus keeping the scraper surface clean. This ensures that the first scraper, arc plate and second scraper maintain a stable scraping effect and helps to extend their service life. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The embodiments disclosed in this application are as follows: Figure 1-6The shown is a tin scraping device for a double-head tin dipping machine, including a base 1, a tin furnace 2 fixedly connected to the top of the base 1, tin dross collection tanks 3 fixedly connected to both sides of the tin furnace 2, a protective shell 4 fixedly connected to the top of the base 1, a connecting shell 5 fixedly connected to one side of the protective shell 4, a drain pipe 6 connected to one side of the connecting shell 5, and a scraping component provided on the connecting shell 5. The scraping assembly includes an electric push rod 7, which is installed inside the protective housing 4. The output end of the electric push rod 7 is fixedly connected to a fixing plate 8. The fixing plate 8 is slidably connected to the inner side of the connecting housing 5 and to the inner side of the tin furnace 2. The bottom end of the fixing plate 8 is fixedly connected to a first scraper 9, which has a tapered cross section. A cleaning mechanism is provided on the connecting shell 5. Two arc-shaped plates 10 are fixedly connected to the fixing plate 8. The arc-shaped plates 10 are circular arcs, and the two arc-shaped plates 10 are staggered at the bottom of the fixing plate 8. A second scraper 11 is fixedly connected to the fixing plate 8. An inclined groove 12 is opened on one side of the second scraper 11. The inclined groove 12 is V-shaped. By utilizing the V-shaped effect of the inclined groove 12 on one side of the second scraper 11, impurities can be gathered towards the center during scraping, removing large oxide layers and impurities. The staggered distribution and arc-shaped effect of the two arc-shaped plates 10 can be used for secondary cleaning of residual small oxide particles and impurities. Then, the first scraper 9 can be used to smooth the surface of the cleaned molten tin, reducing the fluctuation of the molten tin surface, thereby achieving multi-stage scraping and helping to improve the cleaning effect on the surface of the molten tin.

[0021] Reference Figure 6 and Figure 5 As shown, the cleaning structure includes a stepper motor 13, which is mounted on one side of the connecting housing 5. A lead screw 14 is fixedly connected to the output end of the stepper motor 13, and the lead screw 14 is rotatably connected to the inside of the connecting housing 5. A threaded plate 15 is threadedly connected to the outside of the lead screw 14. A cavity is formed on the inner side of the threaded plate 15, which is adapted to the outer side of the fixing plate 8. The threaded plate 15 is slidably connected to the outer side of the fixing plate 8. A brush plate 16 is fixedly connected to the inner side of the threaded plate 15. A diversion pipe 17 is provided inside the threaded plate 15, and multiple nozzles 18 are connected to one side of the diversion pipe 17. The nozzles 18 are inclined on one side of the threaded plate 15. The base 1 is topped with... A water pump 19 is installed at one end. Both the output and input ends of the water pump 19 are connected to a connecting hose 20. One end of the connecting hose 20 extends to the inside of the threaded plate 15 and is connected to one side of the diverter pipe 17. The threaded plate 15 can be driven to reciprocate on the outside of the fixed plate 8 by the lead screw 14 through the thread. This can drive multiple nozzles 18 and brush plates 16 to clean the surfaces of the first scraper 9, the arc plate 10 and the second scraper 11 at the bottom of the fixed plate 8. This can reduce the adhesion of molten solder, keep the scraper surface clean, and enable the first scraper 9, the arc plate 10 and the second scraper 11 to maintain a stable scraping effect.

[0022] Working principle of this utility model: This utility model designs a solder scraping device for a double-head soldering machine, the specific structure of which is shown in the attached instruction manual. Figure 1-6 As shown, in this technical solution, through the cooperation between various structures, when it is necessary to scrape off the oxidized molten tin on the surface of the tin furnace 2, the electric push rod 7 is first activated by the external controller. The electric push rod 7 pushes the fixed plate 8 to move, so that the fixed plate 8 can move the first scraper 9, the arc plate 10 and the second scraper 11 to above the tin furnace 2, and all of them can come into contact with the oxidized molten tin. Utilizing the "V"-shaped effect of the inclined groove 12 on one side of the second scraper 11, the molten tin on both sides can be pushed and scraped towards the surface of the tin furnace 2. The molten tin is collected in the middle and can remove the oxide layer over a large area. Then, the two arc-shaped plates 10 can be used to clean the residual fine slag a second time. The arc shape of the two arc-shaped plates 10 can also collect the slag during the cleaning process, making it easier to move the slag. At the same time, the first scraper 9 can perform three scraping operations, which can effectively clean the oxidized molten tin. The scraped molten tin can be pushed by the fixed plate 8 into the molten tin collection tank 3, so that the waste can be collected through the molten tin collection tank 3. After the soldering is completed, the fixing plate 8 can be moved into the connecting housing 5. Then, the water pump 19 is started, which draws out the external cleaning fluid and delivers it to the diversion pipe 17. The diversion pipe 17 then distributes the cleaning fluid to multiple nozzles 18. Utilizing the inclined design of the nozzles 18, the area below the fixing plate 8 can be sprayed. Simultaneously, the stepper motor 13 is started, which drives the lead screw 14 to rotate. This causes the lead screw 14 to drive the threaded plate 15 to move via the thread, thereby moving the threaded plate 15. 5 can drive the brush plate 16 and multiple nozzles 18 to move. The inner cavity of the threaded plate 15 is adapted to the outer side of the fixed plate 8, so that the threaded plate 15 can drive the brush plate 16 to contact the outer side of the fixed plate 8 and cooperate with the spray of multiple nozzles 18. This allows the brush plate 16 to spray and sweep the outer side of the first scraper 9, the arc plate 10 and the second scraper 11 for cleaning. This allows the fixed plate 8 to clean the first scraper 9, the arc plate 10 and the second scraper 11 in time after the scraping work is completed, thereby reducing the adhesion of molten solder.
