Abstract
The utility model belongs to the technical field of welding mechanisms, and particularly relates to a thermocompression welding nozzle structure, which comprises a first connecting part, a second connecting part and a welding nozzle part, wherein the first connecting part is connected with the second connecting part through the welding nozzle part; and a groove is arranged on the bottom face of the welding nozzle part, so that a welding nozzle can realize accurate positioning when compressing a PCM (Printed Circuit Module) and an FPC (Flexible Printed Circuit). When acting force of downward compression of the welding nozzle is contacted with the PCM, the acting force is dispersed around through the groove, so that the welding nozzle can be uniformly and stably pressed on the PCM, the welding preset position of the PCM and the FPC can be located, and unhealthy phenomena such as pseudo welding and tin connecting during a welding process are avoided; during batch production, the yield after welding is improved, and inconvenience cannot be brought to the PCM test of a protection plate of a post-process battery.
Description
Technical field
The utility model belongs to welding mechanism technical field, relates in particular to a kind of thermocompression bonding and chews structure.
Background technology
At present, in lithium battery production field, need to weld the baffle PCM of battery and the soft board FPC of Belt connector that produce, in the time of welding, one block protection plate need to weld multiple solder joints, and what PCM and FPC were compressed to location and welding is that thermocompression bonding is chewed, the effect of both playing briquetting is chewed in thermocompression bonding, reach again the function of welding, usually, tradition thermocompression bonding is chewed and is had following shortcoming: the head that weldering is chewed is a plane, chew and move downward while compressing PCM and FPC when weldering, the power that first touches PCM can make PCM and FPC determine bit position change, will cause like this welding position not accurate enough, PCM and FPC determine bit position often can be unstable, and in welding process, often have a rosin joint, connect the bad phenomenon such as tin, when batch production, substandard products after welding can increase, make troubles can to the baffle PCM test of rear operation battery simultaneously.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provide a kind of thermocompression bonding to chew structure, be provided with groove by chewing head in the weldering of this structure, weldering is chewed in the time compressing PCM and FPC and can realize accurate location, and in welding process, do not have rosin joint, connect the bad phenomenon such as tin; In the time of batch production, the yields after welding improves, and makes troubles can not to the baffle PCM test of rear operation battery.
For achieving the above object, the utility model adopts following technical scheme: structure is chewed in a kind of thermocompression bonding, comprise the first connecting portion, the second connecting portion and weldering bottle neck, described the first connecting portion is connected with described the second connecting portion by described weldering bottle neck, and the bottom surface of described weldering bottle neck is provided with groove.
Chew the one of structure as thermocompression bonding described in the utility model and improve, that the cross sectional shape of described groove is set to is square, semicircle or half elliptic.
Chew the one of structure as thermocompression bonding described in the utility model and improve, the degree of depth of described groove is 0.3 ~ 0.5mm.
Chew the one of structure as thermocompression bonding described in the utility model and improve, the degree of depth of described groove is 0.35 ~ 0.45mm.
Chew the one of structure as thermocompression bonding described in the utility model and improve, the quantity of described groove is set to four, and four described grooves are distributed in the bottom surface of described weldering bottle neck uniformly.
Chew the one of structure as thermocompression bonding described in the utility model and improve, the side of described weldering bottle neck is provided with weldering temp.-sensing wire hole.
Chew the one of structure as thermocompression bonding described in the utility model and improve, described the first connecting portion and described the second connecting portion are provided with fixing hole.
The beneficial effects of the utility model are: the utility model comprises the first connecting portion, the second connecting portion and weldering bottle neck, the first connecting portion is connected with the second connecting portion by weldering bottle neck, the bottom surface of weldering bottle neck is provided with groove, being arranged so that weldering is chewed in the time compressing PCM and FPC and can realizing accurate location by groove, weldering is chewed the active force of downward compression in the time of contact PCM, its active force disperses to surrounding by groove, thereby make weldering chew even and stable being pressed on PCM, can have good positioning like this PCM and FPC need to weld precalculated position, and the utility model does not have rosin joint in welding process, connect the bad phenomenon such as tin, in the time of batch production, the yields after welding improves, and makes troubles can not to the baffle PCM test of rear operation battery.
