Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric soldering irons, in particular to an electric soldering iron with a rollable spherical soldering iron head. Background Art
[0002] The electric soldering iron currently used is used for welding when the EVA film is laminated or stacked. When a slip film occurs after a layer of EVA is laid, the electric soldering iron is used to fix the EVA film with a hot spot. When the existing electric soldering iron is used to fix the EVA film with a hot spot, three problems are likely to occur:
[0003] First, the EVA film is usually fixed by hot-stamping at three points on one side of the long side of the component. The manual hot-stamping operation time exceeds the average pause time of the assembly line, and generally only 1-2 points can be hot-stamped.
[0004] Second, the hot spot area is small and the adhesion is not strong. After flowing on the assembly line, the EVA film is easy to fall off again due to inertia, and the slip film phenomenon will still occur.
[0005] Third, it is easy for the soldering iron tip to scratch the EVA film before the hot spot is finished and the assembly line has already started to flow. Utility Model Content
[0006] In view of the above problems existing in the existing electric soldering irons, the present utility model is proposed.
[0007] Therefore, the utility model aims to provide an electric soldering iron with a rollable spherical soldering iron tip, which solves the problem that the electric soldering iron is inefficient and may scratch the EVA film during use.
[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0009] An electric soldering iron with a rollable spherical soldering iron tip comprises an outer tube and a soldering iron tip movably plugged into the outer tube, wherein one end of the soldering iron tip located outside the outer tube is provided with a mounting groove, a ball head is rotatably arranged inside the mounting groove, two screw rods are symmetrically rotatably arranged on the outer wall of the outer tube, sliders are threadedly sleeved on the rod walls of the two screw rods, and L-shaped rods are fixedly connected to the side walls of the two sliders, two jacks are symmetrically arranged on the side wall of the outer tube, two slots are symmetrically arranged on the outer wall of the soldering iron tip, the two L-shaped rods are movably inserted into the corresponding jacks and the corresponding slots respectively, a sleeve is movably sleeved on the outside of the outer tube, a driving mechanism is arranged inside the sleeve, and the two screw rods are drivingly connected to the driving mechanism.
[0010] Preferably, the driving mechanism comprises two racks and two gears, the two racks are symmetrically fixed on the inner wall of the sleeve, the two gears are respectively fixedly sleeved with the rod walls of the corresponding screw rods, and the two racks are respectively meshed and connected with the corresponding gears.
[0011] Preferably, an annular plate is fixedly sleeved on the surface of the outer tube, a spring is fixedly connected between the annular plate and the sleeve, and the spring is movably sleeved on the outer tube.
[0012] Preferably, a silicone rubber sleeve is fixedly sleeved on the surface of the sleeve.
[0013] Preferably, the two L-shaped rods are both plastic rods.
[0014] Preferably, a limiting block is fixedly provided on the outer wall of the outer tube, a limiting groove is provided on the inner wall of the sleeve, and the limiting block is slidably provided inside the limiting groove.
[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0016] In the utility model, the electric soldering iron is kept powered on and preheated to the working temperature. When the semi-finished component flows to the manual operation table, the ball head of the electric soldering iron is tightly combined with the surface of the EVA film at the spot heating position, and the ball head rolls at the spot heating position to heat the EVA film to melt and adhere to the glass, forming a firmly attached area. When the assembly line starts to flow, the electric soldering iron is lifted to complete the spot heating of the EVA film. The design of the spherical and rollable soldering iron head increases the EVA spot heating area, improves the adhesion firmness, and prevents the EVA film from being scratched by the electric soldering head.
