Description

Technical Field

[0001] The utility model relates to the technical field of electronic product manufacturing, in particular to wave soldering equipment. Background Art

[0002] Wave soldering equipment is a machine specifically designed for soldering electronic components. Its operating principle is based on pumping, which creates special solder material waves on the surface of the molten liquid solder. When the assembled component with the electronic components passes through these waves at a certain angle and depth, a mechanical and electrical connection is created between the component's solder terminals or pins and the printed circuit board pads, thus achieving soldering.

[0003] Patent document CN221064735U discloses a wave soldering device, which discloses that "it includes: a tin furnace, a mechanical mounting plate, a transmission shaft, and a sealing structure. The transmission shaft is placed in a closed space to rotate and transmit power, while limiting the range of flow of the surrounding tin liquid; the sealing structure isolates the closed space from the oxygen flow in the outside air in a solid form; further, by providing a pipe joint to fill the sealed space with inert gas or grease in a gaseous or liquid form to isolate the oxygen in the outside air, the closed space can be deprived of the oxygen required for the oxidation of the tin liquid, thereby greatly reducing the production of tin oxide."

[0004] However, the wave soldering equipment disclosed in the above-mentioned document mainly focuses on significantly reducing the generation of tin oxide, which is not convenient for preheating components.

[0005] In view of this, it is necessary to develop a preheating mechanism to preheat the components of the PCB, so that the solvent in the flux can evaporate quickly and activate the flux, remove the oxide layer on the PCB pads and component solder ends, and lay the foundation for high-reliability welding. Utility Model Content

[0006] The purpose of the present utility model is to provide a wave soldering device to solve the technical problem raised in the above background technology of enabling the wave soldering device to have a preheating function.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: a wave soldering device comprising: a soldering base, a conveyor assembly mounted on top of the soldering base, a soldering frame mounted on top of the conveyor assembly, a preheating mechanism provided on the inner wall of the soldering frame, the preheating mechanism being used to preheat components on a PCB, rapidly volatilize the solvent in the flux and activate the flux, remove oxide layers from PCB pads and component solder terminals, and thus lay the foundation for high-reliability soldering;

[0008] The preheating mechanism includes a preheating heating wire, which is arranged on the inner wall of the welding frame, the inner wall of the welding frame is installed with a partition, the outer wall of the partition is provided with multiple groups of positioning holes, the outer wall of the welding frame is installed with a storage frame, the inner wall of the storage frame is installed with a flux shell, the inner wall of the storage frame is provided with an adjusting screw groove, the inner wall of the adjusting screw groove is installed with an adjusting screw, the outer wall of the adjusting screw is installed with a fixing block, and the inner wall of the welding frame is installed with a positioning adsorption block.

[0009] Preferably, a gantry is installed on the top of the welding base, and a welding assembly is provided on the outer wall of the gantry.

[0010] Preferably, the outer wall of the welding frame is provided with a smoking and cooling mechanism, which is used to absorb the smoke generated during welding and cool the product to strengthen its stability.

[0011] Preferably, the smoking cooling mechanism includes a mounting groove, and the mounting groove is provided on the outer wall of the welding frame.

[0012] Preferably, an electric push rod is installed on the inner wall of the installation groove, and a processing box is installed on the output end of the electric push rod.

[0013] Preferably, the inner wall of the processing box is provided with a circulation groove, and the inner wall of the processing box is installed with an adsorption fan.

[0014] Preferably, a frame is installed on the top of the processing box, a fixed pole is installed on the bottom of the frame, a fixed frame is installed on the output end of the fixed pole, and an activated carbon plate is installed on the inner wall of the processing box.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model is equipped with a preheating mechanism to preheat the components of the PCB, so that the solvent in the flux can be quickly volatilized and activated, and the oxide layer of the PCB pads and component solder ends can be removed, thus laying the foundation for high-reliability soldering. The existing wave soldering equipment cannot preheat the components, which makes it impossible to quickly volatilize the solvent in the flux and activate the flux, remove the oxide layer of the PCB pads and component solder ends, thus laying the foundation for high-reliability soldering. Therefore, it is necessary to improve this. First, a suitable partition is placed in the welding frame, and the partition is adsorbed and fixed by the positioning adsorption block. Then, the component is fixed on the partition through the positioning hole, and then the adjusting screw is rotated to move the fixing block, and the flux shell is taken out, and then the component is added with liquid, and the component is preliminarily heated along with the preheating heating wire, thereby achieving the desired effect.

[0017] 2. The utility model is equipped with a smoking and cooling mechanism to adsorb the smoke generated during welding, and at the same time cool the product to strengthen its stability. When welding PCB components, smoke may appear, and the heat on the components cannot be quickly adsorbed after welding, so this needs to be improved. First, the activated carbon plate is moved to the inside of the processing box, and then the fixed pole is driven to move the fixed frame to fix the position of the activated carbon plate. Then the electric push rod is driven to move the processing box so that it fits with the outer wall of the welding frame. Then the adsorption fan is driven to adsorb the smoke and residual heat, thereby achieving a special effect. BRIEF DESCRIPTION OF THE DRAWINGS
