In order to achieve the above object, the technical solution adopted in the utility model is, a kind of to weld for puncturing between plastic plate
The soldering tip for connecing, for the first plastic plate is welded on the second plastic plate, the soldering tip includes base portion and is located at base the soldering tip
Puncture portion below portion, the puncture portion are multiple puncture needles, and the puncture needle is distributed on the lower surface of base portion.
A kind of soldering tip for puncturing welding between plastic plate as above, further illustrates as the puncture needle is stretched
Enter to 1/to two/3rds that the length in the second plastic plate is the second plastics plate thickness.
A kind of soldering tip for puncturing welding between plastic plate as above, further illustrates as the puncture needle is
It is cylindric.
A kind of soldering tip for puncturing welding between plastic plate as above, further illustrates as the puncture needle
A diameter of 1.3～1.7mm.
A kind of soldering tip for puncturing welding between plastic plate as above, further illustrates as the puncture needle
Radial cross-section is star.
A kind of soldering tip for puncturing welding between plastic plate as above, further illustrates as the puncture needle
Radial cross-section is regular polygon.
A kind of soldering tip for puncturing welding between plastic plate as above, further illustrates as the base portion includes
The head being coaxially disposed and root, the diameter with diameter greater than root of the head is in arc surface between the head and root
Transition connects, and the puncture needle is distributed on the lower surface of root.
The beneficial effects of the utility model are：This welding head structure is simple, and the solder joint that soldering tip is welded is attractive in appearance, while solder joint connection
Intensity is big, can reach good welding effect, can effectively ensure that bonding strength requirement and Forming Quality between two plastic plates.

Specific embodiment
Below in conjunction with the accompanying drawings the utility model embodiment is further elaborated.
As shown in Figure 1 to Figure 2, a kind of soldering tip for puncturing welding between plastic plate that the utility model is provided, it is described
Soldering tip is for the first plastic plate 1 is welded on the second plastic plate 2, described to puncture the one kind for being welded as ultrasonic bonding, welding
When, the first plastic plate 1 being directed through, is reached in the second plastic plate 2, the bundle for making plastic material deep is entered, then pressurize cooling
Shaping.
The soldering tip includes base portion 3 and the puncture portion below base portion 3, and the puncture portion is multiple puncture needles 4, described
Puncture needle 4 is distributed on the lower surface of base portion 3, during welding, and puncture needle 4 needs guiding through the first plastic plate 1 and extend into the second plastic plate 2
In, the lower surface of base portion 3 is contacted with the upper surface of the first plastic plate 1.The puncture needle 4 is extend in the second plastic plate 2
Length is 1st/to two/3rds of 2 thickness of the second plastic plate, i.e. the length of puncture needle 4 is the thickness of the first plastic plate 1
With 1st/1 to two/3rds of 2 thickness of the second plastic plate summation, such as thickness of the first plastic plate 1 is h1, and second moulds
The thickness of flitch is h2, then the length of puncture needle 4 is h1+ (1/3～1/2) h2, it is ensured that puncture needle 4 extend into the second plastic plate
In 2, it is ensured that the weld strength of two plastic plates.As the plastic plate variable thickness that need to weld is fixed, i.e., the length of puncture needle 4 is not
It is fixed, but as long as ensureing that puncture needle 4 extend into the position in the second plastic plate 2, the length of puncture needle 4 is may thereby determine that, weldering is made
Connect intensity to be guaranteed, while ensureing the presentation quality of welding.
The puncture needle 4 is cylindric, i.e., radial cross-section is circle, a diameter of 1.3～1.7mm of the puncture needle 4.
The radial cross-section of the puncture needle 4 may be arranged as star or regular polygon, be set to star or regular polygon, can make weldering
Point is more attractive in appearance, with good practicality and sight.Can also by the radial cross-section of puncture needle 4 be set to ellipse or
It is other irregular figures.The arrangement in regular polygon on 3 end face of base portion of puncture needle 4 on soldering tip simultaneously, makes between plastic plate
Welding position it is more attractive in appearance, while bonding strength and the uniformity of solder joint can be ensured.
Preferably, the base portion 3 includes the head 301 being coaxially disposed and root 302, the diameter of the head 301 is big
Connect in arc surface transition between the diameter of root 302, the head 301 and root 302, it is also possible to be directly connected to, in platform
Rank shape shaft, the puncture needle 4 are distributed on the lower surface of root 302.During welding, head 301 is made to be connected with supersonic welder.
302 structure of head 301 and root is set to, while ensure that soldering tip bulk strength, mitigates soldering tip weight.
The utility model is not limited to examples detailed above, in the utility model limited range, those skilled in the art
The various modifications or modification that can be made without creative work are protected by this patent.
