Abstract
The invention relates to a fused-drop welding assembly and a fused-drop welding process. The fused-drop welding assembly comprises a spot-welding head, a heating-core assembly and a soldering-tin conveying channel, wherein the soldering-tin conveying channel is a closed channel which is only provided with a soldering-tin inlet and a soldering-tin outlet, and the soldering-tin outlet is formed in the spot-welding head. After a soldering-tin wire is cut into one or several segments, the cutoff soldering-tin wire is sent into the soldering-tin conveying channel after a pulsed gas flow is introduced into a gas-inlet pipe. The other path of gas is introduced into the same path of gas-inlet pipe, and the gas and the soldering-tin wire are simultaneously heated by a heating body, so that the soldering-tin wire is rapidly molten in the channel, and molten soldering tin is blown out of the soldering-tin outlet. According to the fused-drop welding assembly and the fused-drop welding process, the procedure of aligning the spot-welding head with a tin-discharging head is omitted, so that the fused-drop welding assembly is convenient to use; moreover, the fused-drop welding assembly has the advantages of pulsed feeding, uniform welding spots and controllable tin quantity.
Description
Technical field
The present invention relates to a kind of molten drop weldering assembly and molten drop Welding.
Background technology
Solder stick is arranged on out in tin-tube by existing soldering robot, and by going out tin-tube, go out the first-class tin device that goes out formed of tin and be fixed on soldering appliance, the tin head that goes out of then using tin device is aimed at spot welding head position, the action of imitate manual scolding tin.This mode requires very high to going out tin head with the rate of aiming at spot welding head position, but the complex structure of actual soldering robot, the relative position going out tin head and spot welding head adjusts inconvenience, therefore in practical operation, not only inconvenient operation, and affect welding efficiency and welding effect.
In addition, because spot welding head needs the process through a tin sticky, soldering tip can be made to have certain loss, thus spot welding head is constantly changed, this adds use cost undoubtedly.
Summary of the invention
The technical problem to be solved in the present invention is: require high in order to overcome existing spot welding head with the rate of aiming at going out tin head, and adjustment is inconvenient, and the process of tin sticky makes the deficiency that spot welding head loss is fast, the invention provides a kind of molten drop weldering assembly and molten drop Welding.
The technical solution adopted for the present invention to solve the technical problems is: a kind of molten drop weldering assembly, comprise spot welding head and heating core assembly, described heating core assembly comprises heater, described heater is arranged near described spot welding head, also comprise scolding tin transfer passage, described scolding tin transfer passage is the airtight passage only with scolding tin entrance and scolding tin outlet, and described scolding tin outlet is arranged on spot welding head position.
Described scolding tin entrance is connected with a road air inlet pipeline.After solder stick is cut into quantitative one section or several sections by preceding working procedure, by passing into air pulse in this road air inlet pipeline, the solder stick after cutting off being sent in the scolding tin transfer passage of molten drop weldering assembly, realizes the supply successively of material.After solder stick completes and cuts off operation, another road gas passed in the air inlet pipeline of same road, this gas and solder stick are heated by heater simultaneously, thus the gas after heating transfers heat to solder stick again, solder stick is melted fast in passage, and by the scolding tin after melting from scolding tin outlet blowout.
As preferably, it is inner that described scolding tin transfer passage all or part of is arranged on described heater.
In order to ensure scolding tin just in time in scolding tin outlet fusing, described scolding tin outlet is provided with obstruction structure, and solid-state scolding tin is stopped, and liquid solder flows out.The bore of control channel inside can be more than or equal to the external diameter of scolding tin, the bore of scolding tin outlet from large to small, narrows down to the external diameter being less than scolding tin, like this, if scolding tin is to exit or solid-state, exit will be trapped in and continue heating, until could discharge after fusing.
A kind of embodiment of scolding tin outlet is, described scolding tin outlet has step, and the bore that described step makes scolding tin export diminishes to passage from passage.
The another kind of embodiment of scolding tin outlet is, described scolding tin outlet is pyramidal structure, and the bore that scolding tin is exported diminishes to passage from passage.
Because spot welding head is field-replaceable unit, for the ease of changing and saving use cost, described scolding tin transfer passage is formed by two connected carrier pipes, wherein one is communicated with scolding tin outlet, another root is communicated with scolding tin entrance, that root carrier pipe and spot welding head, heating core of being communicated with scolding tin outlet can be arranged to integrative-structure, jointly form a spot welding head assembly, change as field-replaceable unit.
Because the length of carrier pipe can exist mismachining tolerance, one end of the described carrier pipe be communicated with scolding tin entrance is arranged with spring, and the other end is provided with seal connector, and described seal connector is connected with another root carrier pipe.Seal connector makes two carrier pipes combine closely, and keeps the sealing of junction, makes that tin silk is smooth and easy to be entered; Meanwhile, after the other end arranges spring, that root carrier pipe being communicated with scolding tin entrance can be made when carrier pipe is partially long to stretch out suitable length outward, eliminate error in length, facilitate the installation of spot welding head assembly.
In order to prevent follow-up parts, particularly the connecting line of heating core assembly is by the impact of heating heat, and also comprise a thermal insulation board, described thermal insulation board ring is located at outside described scolding tin transfer passage, and is arranged on the afterbody of described heating core assembly or leans on caudal position.
The invention still further relates to a kind of molten drop Welding, adopt molten drop of the present invention to weld assembly, comprise the following steps:
A solder stick is cut into one section or several sections by ();
B the solder stick of cutting into chunks in step (a) is sent in the scolding tin transfer passage of molten drop weldering assembly by air pulse from the scolding tin entrance of molten drop weldering assembly by ();
C () before the step (a) or simultaneously or afterwards, passes into another road gas from the scolding tin entrance of molten drop weldering assembly, makes the scolding tin after melting from the scolding tin outlet blowout of molten drop weldering assembly in scolding tin transfer passage.
Step (c) before the step (a) or simultaneously, like this, after the gas passed into heats in advance, then transfers heat to solder stick, solder stick is melted fast in passage.
The invention has the beneficial effects as follows, molten drop of the present invention weldering assembly and molten drop Welding, will send tin device and spot welding head to be combined into one, and eliminate spot welding head and the program going out tin head and aim at, easy to use; And pulse feeding, solder joint is even, and tin amount is controlled; Spot welding head does not have tin sticky loss, reduces use cost.
