Description

Technical Field

[0001] This invention relates to the field of resistance lap welding technology, specifically an automatic solder feeding device. Background Technology

[0002] Lap welding with added silver solder is a process that uses silver-based alloy solder as a filler material to weld at the lap joint, significantly improving conductivity and connection strength. It is widely used in electronics, automotive, aerospace, refrigeration, and precision tool manufacturing, such as circuit board connections and automotive engine component welding.

[0003] The existing lap welding technique with added silver solder has the following drawbacks: 1. Waste of personnel: Welding and adding silver solder sheets require separate personnel, resulting in wasted personnel.

[0004] 2. Risk of omission: Since this operation is done manually, operators are prone to fatigue during long periods of operation, which may lead to omission.

[0005] 3. Low efficiency: Welding can only begin after the operator has finished adding the silver solder pads, resulting in long waiting times at the welding station (5 seconds for a single piece). To address this issue, we have proposed an automatic solder feeding device. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic solder feeding device to solve the problems mentioned in the background art, which require independent personnel to complete the welding and silver soldering, and the risk of missed feeding due to long-term manual operation and the long waiting time at the welding station.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic solder feeding device, comprising a frame, a fixed frame connected to the outer side of the frame, a solder mechanism provided on the surface of the fixed frame, the solder mechanism comprising a base, a feeding cylinder, a movable base plate, a movable pressure plate, a first pressing cylinder, a bracket, a material tray, a fixed base plate, a fixed pressure plate, a second pressing cylinder, and a discharge port. The fixed frame has a base, the base has a feeding cylinder, the feeding cylinder has a movable base plate on its outer side, a movable pressure plate is located at the upper end of the movable base plate, the first pressing cylinder is located inside the movable pressure plate, a bracket is located on one side of the base near the feeding cylinder, a material tray is located inside the bracket, a fixed base plate is located on the other side of the feeding cylinder, a fixed pressure plate is located at the top of the fixed base plate, the second pressing cylinder is located inside the fixed pressure plate, and a discharge port is located on the outer side of the fixed base plate.

[0010] Preferably, a pressure shaft is movably connected to the outer side of the bracket, and the pressure shaft is L-shaped.

[0011] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes an automatic silver solder sheet feeding mechanism. The feeding action of the solder sheet is achieved through the extension and retraction of a cylinder, solving problems such as labor waste, the risk of missed feeding, and efficiency bottlenecks. It shortens the processing cycle time, increases production capacity, and is not only simple and convenient, but also highly efficient and easily automated, thus greatly improving product processing efficiency. It ensures the product production cycle time, improves the product qualification rate and production efficiency, and facilitates operation for workers. Automatic silver sheet feeding is achieved through the forward and backward movement of a sliding table cylinder and the alternating pressing of a threaded cylinder.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-2 An embodiment of the present invention provides an automatic solder feeding device, comprising a frame 1, a fixed frame 2 connected to the outer side of the frame 1, and a solder feeding mechanism 3 disposed on the surface of the fixed frame 2. The solder feeding mechanism 3 includes a base 303, a feeding cylinder 304, a movable base plate 305, a movable pressure plate 306, a first pressure cylinder 307, a bracket 308, a material tray 309, a pressure shaft 310, a fixed base plate 311, a fixed pressure plate 312, a second pressure cylinder 313, and a discharge port 314. The fixed frame 2 is provided with the base 303, and the base 303 is provided with the feeding cylinder 304 for feeding. A movable base plate 305 is provided on the outside of the cylinder 304. A movable pressure plate 306 is provided on the upper end of the movable base plate 305. A pressing cylinder 307 is provided inside the movable pressure plate 306. A bracket 308 is provided on the surface of the base 303 on one side of the feeding cylinder 304. A material tray 309 is provided inside the bracket 308. A fixed base plate 311 is provided on the other side of the feeding cylinder 304. A fixed pressure plate 312 is provided on the top of the fixed base plate 311. A pressing cylinder 313 is provided inside the fixed pressure plate 312. A discharge port 314 is provided on the outside of the fixed base plate 311. This device, through the setting of solder mechanism 3, solves the problem that welding and adding silver solder sheets need to be completed by independent personnel. Manual operation can easily lead to operator fatigue and the risk of missing additions during long periods of operation, and also results in long waiting times at the welding station.

[0017] Furthermore, a pad 302 is bolted to the outer side of the fixing frame 2, and lifting blocks 301 are connected to both sides of the pad 302. The bottom of the base 303 is fixedly connected to the lifting blocks 301. Figure 2 As shown, this structure is used to adjust the height of the base 303 by connecting the lifting support block 301 and the pad block 302, making it suitable for people of different heights.

[0018] Furthermore, the feeding cylinder 304 is mounted on the base 303, the movable base plate 305 is mounted on the slide of the feeding cylinder 304, the movable pressure plate 306 is fixed on the movable base plate 305, the top of the movable pressure plate 306 is equipped with a first pressing cylinder 307, the surface of the base 303 is equipped with a fixed base plate 311, the top of the fixed base plate 311 is equipped with a fixed pressure plate 312, and the second pressing cylinder 313 is mounted on the fixed pressure plate 312. Figure 2As shown, this structure is used to press the material at the material tray 309 under the action of the moving pressure plate 306 and the moving base plate 305 by activating the pressing cylinder 307. Then, the feeding cylinder 304 is activated to move the moving base plate 305 and the welding piece to the fixed base plate 311. The welding piece extends. After receiving the welding completion signal, the pressing cylinder 313 drives the fixed pressure plate 312 to extend and cooperate with the fixed base plate 311 to press the welding piece. At the same time, the pressing cylinder 307 retracts under the action of the feeding cylinder 304, completing one feeding cycle.

[0019] Furthermore, a pressure shaft 310 is movably connected to the outer side of the bracket 308. The pressure shaft 310 is L-shaped and connected to the output end of the threaded cylinder, driving the pressure shaft 310 to swing and alternately press the silver solder sheet, thereby achieving automatic silver sheet feeding. Figure 2 As shown, this structure is used to restrict the material at the material tray 309 by the natural downward hanging of the pressure shaft 310, so as to prevent the material from shifting.

[0020] Working principle: When using, such as Figure 1 and Figure 2 As shown, the material tray 309 is placed at the support 308, and the position of the pressing shaft 310 is adjusted so that it presses against the material surface. The foot pedal at the pressing cylinder 313 is stepped on to retract the pressing cylinder 313. The pressing cylinder 307 is activated to press the material at the material tray 309 under the action of the moving pressure plate 306 and the moving base plate 305. Then, the feeding cylinder 304 is activated to move the moving base plate 305 and the welding piece towards the fixed base plate 311. The welding piece extends. After receiving the welding completion signal, the silver welding piece will melt and break during welding. The pressing cylinder 313 drives the fixed pressure plate 312 to extend and cooperate with the fixed base plate 311 to press the welding piece. At the same time, the pressing cylinder 307 retracts under the action of the feeding cylinder 304, completing one feeding. This operation sequence is repeated for each welding. The above is the entire working principle of the present invention.

[0021] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
