Description

Technical Field

[0001] This utility model relates to the field of soldering furnaces, and in particular to a soldering furnace anti-overflow device. Background Technology

[0002] Soldering furnaces are widely used equipment in industrial fields such as electronics manufacturing and electrical assembly. They are mainly used to weld electronic components to circuit boards by melting solder, and are one of the key pieces of equipment to ensure the conductivity and structural stability of electronic devices.

[0003] Existing technologies, such as the utility model patent with publication number CN204449555U, disclose a soldering furnace, including a heating base and a solder pot disposed on the heating base. The soldering furnace also includes a scraper for collecting solder dross generated on the surface of the molten solder. The scraper and the solder pot can generate relative movement to collect the solder dross. The technical solution of this utility model can effectively solve the problems of cumbersome and labor-intensive solder dross cleaning operations in the prior art.

[0004] The inventors discovered during daily use that traditional soldering furnaces typically lack effective overflow protection mechanisms during operation. Due to the absence of a dedicated overflow prevention structure, molten solder easily overflows from the furnace edges when it melts and expands at high temperatures, or when excessive solder is added or the equipment vibrates. This overflowing hot solder not only drips onto the equipment surface, posing a risk of burns, but can also easily seep into the furnace, damaging heating elements, circuit boards, and other critical components, severely impacting production safety and equipment lifespan. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies.

[0006] To solve the above technical problems, this utility model provides a soldering furnace anti-overflow device, comprising: a soldering furnace body, a solder tank formed on the upper surface of the soldering furnace body, a plurality of heat dissipation holes evenly formed on one side of the soldering furnace body, a control switch fixedly connected to one side of the soldering furnace body, a plurality of support legs fixedly connected to the lower surface of the soldering furnace body, an anti-overflow device provided on one side of the soldering furnace body, the anti-overflow device comprising two fixing seats, one side of the fixing seats being fixedly connected to one side of the soldering furnace body, and the two fixing seats being close to each other... A rotating shaft is rotatably connected to the side, and a rotating seat is fixedly connected to the arc surface of the rotating shaft. A top cover is fixedly connected to the upper surface of the rotating seat. An arc hole is opened on one side of the fixed seat, and the center of the arc hole is coaxial with the axis of rotation of the rotating seat. A sliding rod is slidably connected to the inner wall of the arc hole, and the arc surface of the sliding rod is fixedly connected to the rotating seat. A base plate is fixedly connected to one side of the soldering furnace body, and an electric push rod is fixedly connected to the upper surface of the base plate. A guide rail is fixedly connected to the output end of the electric push rod, and the inner wall of the guide rail is slidably connected to the arc surface of the sliding rod.

[0007] The effect achieved by the above components is that during the operation of the soldering furnace, when the temperature of the molten solder is too high or the addition of solder causes the liquid level to rise, the top cover can play a timely blocking role, confining the molten solder inside the furnace. This not only reduces the waste of solder, but also avoids the pollution and damage to the work surface caused by the overflow of molten solder, and reduces the safety hazards caused by the overflow of molten solder.

[0008] Preferably, a telescopic rod is fixedly connected to the upper surface of the base plate, and the output end of the telescopic rod is fixedly connected to the lower surface of the guide rail.

[0009] The aforementioned components achieve the following effects: they assist the electric actuator in pushing the guide rail, providing effective support and constraint to the guide rail and reducing swaying during its movement.

[0010] Preferably, a sealing gasket is fixedly connected to one side of the top cover, and the sealing gasket is made of a high-temperature resistant material.

[0011] The effect achieved by the above components is that when the top cover is closed on the processing port of the soldering furnace body, the sealing gasket will fit tightly with the edge of the furnace opening, forming a sealing barrier. Even if the molten solder boils or shakes slightly due to the increase in temperature, it is difficult to break through this barrier and overflow from the furnace.

[0012] Preferably, an installation opening is provided on one side of the top cover, and a glass plate is fixedly connected inside the installation opening.

[0013] The effect achieved by the above components is that the top cover has a glass plate in the middle, which allows operators to observe the state of the molten tin in the furnace and the progress of workpiece processing at any time, thereby improving the processing efficiency of the workpiece.

[0014] Preferably, the upper surface of the soldering furnace body is provided with a slag scraping device, the slag scraping device includes two support seats, the lower surface of the support seats is fixedly connected to the upper surface of the soldering furnace body, a sliding groove is opened on one side of the support seat, a sliding rod is slidably connected inside the sliding groove, a fixed plate is rotatably connected to one end of the two sliding rods that are close to each other, and a scraper is fixedly connected to one side of the fixed plate.

[0015] The effect achieved by the above components is that the oxidized tin dross on the surface of the molten tin can be scraped off by the scraper. After timely cleaning with the scraper, the molten tin can maintain a good purity and reduce product defects caused by molten tin quality problems.

[0016] Preferably, a collection box is fixedly connected to the upper surface of the soldering furnace body, and the collection box is directly below the scraper.

[0017] The effect achieved by the above components is to collect the solder dross carried away by the scraper after it removes the solder dross from the surface of the molten solder, reduce the dross from the solder, and ensure the safety and stability of the production area.

[0018] Preferably, a handle is fixedly connected to the upper surface of the fixing plate, and the handle has a "U" shaped cross-section.

[0019] The effect achieved by the above components is to enable the rapid movement of the fixed plate, which facilitates the quick scraping of solder dross from the surface of the molten solder by the scraper, thereby improving the flexibility of using the scraper.

[0020] Compared with related technologies, the solder furnace anti-overflow device provided by this utility model has the following beneficial effects: By operating the anti-overflow device, the soldering furnace opening is covered. The sliding rod moves to drive the rotating seat and the top cover to rotate, and the electric push rod pushes the guide rail to move, so that the slide rail and the arc hole limit the movement of the sliding rod, which helps the top cover cover the soldering furnace opening.

[0021] By operating the slag scraping device, the slag on the surface of the molten tin is scraped off. The rotating fixed plate causes the fixed plate near one end of the scraper to lift up. By moving the fixed plate along the inner wall of the trough, it helps the scraper to remove the slag on the surface of the molten tin. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 The present invention provides a soldering furnace anti-overflow device, comprising: a soldering furnace body 1, a soldering tank 4 on the upper surface of the soldering furnace body 1, a plurality of heat dissipation holes 5 evenly distributed on one side of the soldering furnace body 1, a control switch 6 fixedly connected to one side of the soldering furnace body 1, a plurality of support legs 7 fixedly connected to the lower surface of the soldering furnace body 1, an anti-overflow device 2 on one side of the soldering furnace body 1, and a slag scraping device 3 on the upper surface of the soldering furnace body 1.

[0027] In the embodiments of this utility model, please refer to Figure 2 , Figure 3 and Figure 4The anti-overflow device 2 includes two fixed seats 201. One side of the fixed seat 201 is fixedly connected to one side of the soldering furnace body 1. A rotating shaft 202 is rotatably connected to the side of the two fixed seats 201 that is close to each other. A rotating seat 203 is fixedly connected to the arc surface of one side of the rotating shaft 202. A top cover 204 is fixedly connected to the upper surface of the rotating seat 203. An arc hole 205 is opened on one side of the fixed seat 201. A slide rod 206 is slidably connected to the inner wall of the arc hole 205. The arc surface of the slide rod 206 is fixedly connected to the rotating seat 203. A base plate 208 is fixedly connected to one side of the soldering furnace body 1. An electric push rod 209 is fixedly connected to the upper surface of the base plate 208. A guide rail 207 is fixedly connected to the output end of the electric push rod 209. The inner wall of the guide rail 207 is slidably connected to the arc surface of the slide rod 206. During the operation of the soldering furnace body 1, when the temperature of the molten solder is too high or the level rises due to the addition of solder, the top cover 204 can promptly act as a barrier, confining the molten solder within the furnace. This not only reduces solder waste but also prevents contamination and damage to the worktable caused by overflowing molten solder, thus reducing safety hazards caused by spillage. A telescopic rod 210 is fixedly connected to the upper surface of the base plate 208, and the output end of the telescopic rod 210 is fixedly connected to the lower surface of the guide rail 207. This allows the auxiliary electric push rod 209 to push the guide rail 207, providing effective support and constraint and reducing wobbling during movement. A sealing gasket 211, made of high-temperature resistant material, is fixedly connected to one side of the top cover 204. When the top cover 204 is closed over the processing opening of the soldering furnace body 1, the sealing gasket 211 fits tightly against the edge of the furnace opening, forming a sealing barrier. Even if the molten solder slightly boils or sloshes due to temperature rise, it is difficult for it to overflow the furnace through this barrier. A mounting port 212 is provided on one side of the top cover 204, and a glass plate is fixedly connected inside the mounting port 212. A glass plate is designed in the middle of the top cover 204, so that the operator can observe the state of the molten tin in the furnace and the processing progress of the workpiece at any time through the glass plate, thereby improving the processing efficiency of the workpiece. In the embodiments of this utility model, please refer to Figure 5The slag scraping device 3 includes two support seats 31. The lower surface of the support seats 31 is fixedly connected to the upper surface of the solder furnace body 1. A groove 32 is provided on one side of the support seat 31. A sliding rod 33 is slidably connected inside the groove 32. A fixing plate 34 is rotatably connected to the end of the two sliding rods 33 that are close to each other. A scraper 35 is fixedly connected to one side of the fixing plate 34. This achieves the goal of scraping away the oxidized slag on the surface of the molten solder using the scraper 35. After timely cleaning with the scraper 35, the molten solder can maintain a good purity, reducing product defects caused by molten solder quality problems. A collection box 36 is fixedly connected to the upper surface of the solder furnace body 1. The collection box 36 is directly below the scraper 35. This achieves the goal of collecting the slag carried away by the scraper 35 after scraping away the slag on the surface of the molten solder, reducing the slag scattering and ensuring the safety and stability of the production area. A handle 37 is fixedly connected to the upper surface of the fixing plate 34. The cross-section of the handle 37 is "U". The fast-moving fixed plate 34 is achieved, which makes it convenient for the scraper 35 to quickly scrape the solder dross on the surface of the molten solder, thus improving the flexibility of using the scraper 35. The working principle of the anti-overflow device for soldering furnace provided by this utility model is as follows: When soldering parts, the parts and solder need to be placed in the solder bath 4, and then the control switch 6 is turned on to heat the solder in the solder bath 4. When the solder melts and expands at high temperature, it may overflow the solder bath 4. In order to prevent the molten solder in the solder bath 4 from overflowing, the anti-overflow device 2 needs to be used. First, the electric push rod 209 is turned on. The electric push rod 209 pushes and drives the guide rail 207 to move. The movement of the guide rail 207 drives the slide rod 206 on the inner wall of the guide rail 207 to move upward along the inner wall of the guide rail 207 and the arc hole 205. 06 moves upward along the inner wall of the guide rail 207 and the arc hole 205, causing the rotating seat 203 and the rotating shaft 202 to rotate on the inner wall of the fixed seat 201. The rotation of the rotating seat 203 causes the top cover 204 to cover the solder furnace body 1. At this time, the sealing gasket 211 fixedly connected to one side of the top cover 204 can increase the sealing between the furnace opening and the top cover 204 and reduce the overflow of molten solder. Since the top cover 204 is designed with a glass plate in the middle, the operator can observe the state of the molten solder in the furnace at any time through the glass plate, thereby increasing the workpiece yield. When the workpiece is processed, the electric push rod 209 is closed and the top cover 204 of the furnace opening is opened.

[0028] When spot welding workpieces with molten solder in solder bath 4, molten solder will produce dross when it comes into contact with air. In order to reduce the impact of dross on workpieces, a dross scraper 3 is required. Hold handle 37 and press down fixed plate 34 to lift one side of scraper 35. Then move fixed plate 34 along slide 32 towards the end near top cover 204 to move scraper 35 to the side of furnace opening near fixed seat 201. After scraper 35 moves to the side of furnace opening near fixed seat 201, lift handle 37 to flatten scraper 35 on the surface of molten solder. Then move fixed plate 34 away from handle 37 to scrape off dross from the surface of molten solder. After scraping off dross from the surface of molten solder, lift fixed plate 34 again and move scraper 35 out of furnace opening and into collection box 36.

[0029] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
