Description
Technical field
The utility model relates to communication technical field, especially a kind of spot welding positioning seat.
Background technology
In the existing portable terminal, all need battery, for portable terminal provides each professional required electric energy as power supply.Battery mainly comprises electric core, baffle and other dependency structure assembly, for example: external frame.Wherein, need electric core and baffle be linked together by the mode of spot welding.Existing implementation is: nickel strap is spoted weld on the electric core effectively reliably, and then the opposite side of nickel strap is spoted weld on the baffle.In order to reduce to be connected the extra impedance that nickel strap is introduced between electric core and the baffle, nickel strap needs tiny as much as possible, and, in the most existing battery, further the nickel strap of both positive and negative polarity all is arranged on the top of electric core.Because nickel strap is very tiny, spots weld on the electric core it extremely difficult.
As shown in Figure 1, for prior art spots weld a spot welding system schematic diagram on the electric core with nickel strap, wherein, 101 is the pressure thick stick, and 102 is mash welder, be provided with capillary and current feedback circuit in this mash welder 102,103 is nickel strap, and 104 for being used to locate the positioning devices of nickel strap, and 105 is electric core, 106 for being used to locate the pedestal of electric core, and 107 is operating desk.When spoting weld nickel strap on the electric core in the prior art, at first electric core 105 is fixed on the pedestal 106, manually nickel strap 103 is positioned to the position that need spot weld on the electric core 105 by positioning devices 104 again, operating point welding machine 102 is vertically to nickel strap 103 motions then, when the capillary contact nickel strap 103 of mash welder 102, carry out transient large current discharge, nickel strap 103 is spoted weld on the electric core 105.As shown in Figure 2, when carrying out spot welding, the spot welding system schematic diagram the during capillary of mash welder 102 contact nickel strap 103.
In realizing process of the present utility model, the inventor finds that there is following problem at least in prior art:
Because nickel strap is very tiny, be difficult for the location, the less nickel strap of length especially need repeatedly be adjusted the position of nickel strap, and operating efficiency is lower; And the operative employee is positioned to nickel strap when removing positioning devices on the electric core, and tiny nickel strap very easily is shifted, and has reduced the spot welding effect like this, thereby has influenced the qualification rate of battery; In addition, in that the spot welding effect is bad when carrying out repeatedly spot welding, solder joint on the nickel strap can be oxidized, and no longer clean, like this, when nickel strap is carried out next spot welding, because discharge current is bigger, fried fiery phenomenon will appear, and sparks flying off in all directions, may damage the adjacent devices that is splashed spark, injure the operative employee.
The utility model content
The utility model embodiment technical problem to be solved is: effectively locate nickel strap, improve the operating efficiency and the spot welding effect of spot welding.
An aspect according to the utility model embodiment, a kind of positioning seat that provides, comprise pedestal and mash welder, described mash welder comprises capillary and current feedback circuit, the surface of described pedestal offers the electric core groove that is used to carry electric core, the bottom surface of described electric core groove offers the locating slot that is used to locate nickel strap, and the side of described locating slot or bottom surface offer and be used to the capillary hole of accommodating described capillary and described capillary being contacted with described nickel strap.
In the spot welding positioning seat that the utility model embodiment provides, offer the locating slot that is used to locate nickel strap in the bottom surface of electric core groove, because nickel strap is very tiny, be difficult for the location, when the spot welding positioning seat that uses the utility model embodiment to provide is spot welded to nickel strap on the electric core, can nickel strap be located by locating slot, because being moved, nickel strap adjusts the position of nickel strap so repeatedly with regard to not needing, compared with prior art, the utility model embodiment has improved the operating efficiency and the spot welding effect of spot welding, has effectively ensured the qualification rate of battery; In addition; because the side or the bottom surface of locating slot offer the capillary hole that is used to accommodate capillary; capillary can contact the spot welding of going forward side by side with nickel strap by this capillary hole; the utility model embodiment moves to spot welding point the inside of spot welding positioning seat; thereby the spark that spills in the time of can reducing spot welding is effectively protected adjacent devices and operative employee's safety.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
