Thus, the welding device realizes to heat and pressurize the welded objects in a welding process, and meanwhile, to continuously knock the welding objects. Therefore, the high-strength welding of large-scale contacts is ensured, further, the quality of electronic control elements using the large-scale contacts is improved, and the use life is prolonged.
Description
Technical field
The utility model relates to a kind of electrotechnics, relates in particular to a kind of welder.
Background technology
Relay, contactor etc. are electrical field electronic control components commonly used, usually be connected by the contact between the static contact that in these electronic original parts, connects power supply and the moving contact that connects load, can not produce bigger contact resistance if the contact contact is firm, cause the contact-making surface temperature too high, make the face contact become a contact, even not conducting phenomenon occurs.
In the solder technology of existing contact, weld, promptly can guarantee the firm welding between the support of silver point and copper by in the heating of high-frequency induction heating machine, exerting pressure on the silver point for the silver point and the copper support of small dimension (below electric current 110mA).
But the applicant finds, support and silver point for big specification (by electric current greater than 110mA) because contact area is bigger, only adopts existing heating and the condition of exerting pressure can not make silver point and support fully and merge, firmly welding.Carry out the contact welding and improve heating-up temperature, can influence the quality of product on the one hand, can waste energy on the other hand by the power output that improves high frequency heating machine.
The utility model content
The problem that the utility model solves is that big specification sound contact is firmly welded, to guarantee that electronic control component normally uses.
For addressing the above problem, welder of the present utility model comprises: support unit, heating unit, presser unit, described welder also comprises the vibrations unit, described vibrations unit be arranged in presser unit top and with the presser unit mechanical connection.
Optionally, described support unit comprises base, and base is used for the support section of horizontal positioned solder joint.
Optionally, described heating unit is the high-frequency induction heat electric machine.
Optionally, described presser unit comprises cylinder, pressure head and connector, and pressure head links to each other with cylinder, and cylinder provides pressure to pressure head, and the pressure head top is a connector, and pressure head and connector mechanical fixation are together.
Optionally, described ceramic pressure head is a cylinder.
Optionally, the described cylindrical area of a circle is less than the area of the soldered elements of being pressed.
Optionally, described vibrations unit comprises percussion mechanism and vibration motor, and vibration motor is positioned at the top of percussion mechanism, and vibration motor links to each other with presser unit machinery by percussion mechanism.
Compared with prior art, the utlity model has following advantage: welding object is fully merged, guarantee higher weld strength, thereby the product quality of avoiding adopting the mode of heating welding to cause descends and energy waste.

The specific embodiment
Essence of the present utility model is by adding vibration motor and percussion mechanism in welder, in to welding object heating pressurization, welding object being continued to knock, to guarantee higher weld strength.
The utility model mainly comprises four parts: support unit 1, heating unit 2, presser unit 3, vibrations unit 4.Wherein support single 1 yuan, be used for placing and the clamping soldered elements.Heating unit 2 is used for the soldered elements that is positioned over support unit is heated, for welding provides thermal source.Presser unit 3 is used for the soldered elements that is positioned over support unit is exerted pressure, and combines closely to guarantee soldered elements.Vibrations unit 4 is arranged at presser unit 3 tops, exerts pressure to soldered elements in presser unit, and vibrations unit 4 knocks presser unit simultaneously, and the presser unit by rigidity passes to soldered elements with percussion power, soldered elements is fully merged.
In embodiment of the present utility model, support unit 1 mainly comprises base 11.Wherein base 11 is used for the support section of horizontal positioned and fixed contact, and in the present embodiment, support section is that copper supports.After horizontal positioned copper supports, manually on copper supports, be coated with solder paste, and manually silver point lain in a horizontal plane in the copper support, in order to carrying out follow-up welding action.
In embodiment of the present utility model, heating unit 2 is high-frequency induction heating machines, can obtain to weld required temperature by the power output of adjusting the high-frequency induction heat electric machine.In the welding process, center, big specification contact is heated.
In embodiment of the present utility model, presser unit 3 mainly comprises cylinder 31, pressure head 32, connector 33, cylinder 31 provides pressure to pressure head 32, the pressure of pressure head 32 puts on the silver point upper surface, and 1 impels silver point and copper to support combines closely, and connector and pressure head machinery are fixed together.In the present embodiment, pressure head 32 is cylindric, is made by ceramic material.The relevant parameter of ceramic cylinder pressure head is: body diameter is 4mm, and length is 50mm.The size of described cylinder is less than the silver point size.In the welding process, pressure head is exerted pressure at the silver point center, so that the face that touches that big specification contact connects can be evenly stressed.
With reference to figure 2, Fig. 2 is presser unit 3 and vibrations unit 4 stereograms.Vibrations unit 4 is positioned at presser unit 3 tops, and vibrations unit 4 mainly comprises vibration motor 41 and percussion mechanism 42.Wherein vibration motor 41 is positioned at the top of percussion mechanism 42.
With reference to figure 3, Fig. 3 is the profile of stereochemical structure shown in Figure 2.By profile as can be seen vibration motor 41 be fixed together by a mechanical connector 43 with percussion mechanism 42, percussion mechanism 42 contacts with the connector 33 of presser unit, percussion mechanism can separate with the connector 33 of presser unit.
Drive percussion mechanism vertical tremor together during vibration motor work, percussion mechanism constantly knocks the connector of presser unit in vibrations.Because connector and pressure head machinery are fixed together, and the pressure head of presser unit just compressing the upper surface of silver point this moment, so percussion mechanism constantly knocks the silver point upper surface by the connector and the pressure head of rigidity, promotes silver point and supports fully fusion of ground.
In welding process, the contact is heated earlier by heating unit, exert pressure by pressure head butt welding point center by presser unit again, the contact is knocked by presser unit by the vibrations unit simultaneously, to realize the high strength welding, guarantee that big specification contact firmly welds.
Though oneself discloses the utility model as above with preferred embodiment, the utility model is not to be defined in this.Any those skilled in the art in not breaking away from spirit and scope of the present utility model, all can do various changes and modification, and therefore protection domain of the present utility model should be as the criterion with claim institute restricted portion.
