Description
Technical field
The utility model belongs to plastic material technical field, and in particular to a kind of laser welding structure of plastic material.
Background technique
The laser welding of plastic material as the important branch of laser welding technology have been widely used for automobile, electronics and
The fields such as daily necessities.The laser welding the most common form of plastic material is laser transmission welding, the process of this welding technique are as follows:
Two plastic items to be welded are fitted together first, then by the laser orientation in a branch of short-wave infrared area to be bonded
Then position, laser beam are absorbed, laser energy is absorbed so that subsurface material temperature liter by upper layer of material by subsurface material
Height melts upper layer and the plastics with lower layer, to complete to weld.Wherein, upper layer of material requires the flatness of welding surface preferable
(50-100 μm), laser energy is uniformly distributed when just can guarantee welding, to form stronger firm welding degree, reach compared with
Good sealing air-tightness.The more demanding translucent material of current overlying plastic material more options angularity, just can guarantee product
Flatness conform to welding requirements.In this way to the more demanding of welding material, material cost is high, material it is alternative compared with
It is small.Plastic material after-contraction after molding simultaneously, the flatness that will also result in plastic parts is bad, irrational mix design (see
Fig. 1 and Fig. 2) deformation after forming plastic pieces can not be overcome, cause welding quality bad or even welding failure.The meeting of many manufacturers
By purchase high-precision, the laser apparatus of high-energy overcomes these problems, this also causes the investment of equipment to rise, and does not have
Economy.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of novel plastic laser welding structure, avoids plastic cement material
Expect contraction distortion after shaping.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions: a kind of novel plastic
Laser welding structure, including overlying plastic are equipped with replicated structures between the edge and middle part of overlying plastic.
Further, the edge of overlying plastic be equipped with downward turnover frame, make the depression in centre of welding plane in
Edge.
Further, the middle part of welding plane is equipped with criss-cross reinforcing rib.
Further, sinking in the middle part of overlying plastic is heavy platform.
Further, it is connected between the edge of heavy platform and the top surface of overlying plastic with chamfered transition.
Further, the top surface of overlying plastic is set as plane.
Further, the welding plane of overlying plastic is equipped with flash groove to block the flash after welding.
Further, chamfering is equipped on the inside of flash groove.
A kind of ultrasonic radar sensor, including upper plastic cover, upper plastic cover use novel plastic laser as described above
Welding structure.
The utility model is beneficial in that the replicated structures between the edge and middle part of overlying plastic can be effective
The contraction distortion avoided after plastic shaping, keep the alternative of material strong, the cost of material is low.

Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments:
The embodiment one of overlying plastic 1 be equipped with as shown in Figure 3 and Figure 4, between the edge and middle part of overlying plastic 1 to
Under replicated structures 11, make the depression in centre of welding plane in edge, the middle part of welding plane be equipped with it is criss-cross plus
Strengthening tendons 13.The welding plane of overlying plastic 1 is equipped with flash groove 12 to block the flash after welding, is equipped on the inside of flash groove 12
Angle.
The contraction distortion of overlying plastic 1, moulds upper layer after turnover frame 11 cooperates reinforcing rib 13 that can effectively avoid molding
The alternative of the material of material 1 is strong, and the cost of material is low.The plastic cement melted when welding can be overflowed to edge, and flash groove 12 can block
Flash after welding keeps preferable appearance.
The embodiment two of overlying plastic 1 is as shown in figure 5, sinking in the middle part of overlying plastic 1 is heavy platform 15, the top of overlying plastic 1
Face is set as plane, and welding plane is equipped with flash groove 12.Middle part sinking is that the replicated structures of heavy platform 15 are also avoided that upper layer after molding
The contraction distortion of plastics 1.And to solve deformation and reaching preferable welding fastness, how much other manufacturers, which will use fixture, is clamped
The structure of welding surface, this overlying plastic 1 solves the problems, such as deformation, it may not be necessary to which the utilization of tempered glass 2 is used only in fixture
Self weight is compressible welding surface, realizes preferable welding fastness.
The embodiment three of overlying plastic 1 as shown in fig. 6, with being in place of the difference of embodiment two, the edge of heavy platform 15 with
It is connected between the top surface of overlying plastic 1 with chamfered transition, replicated structures can keep uniform meat thick, this structure can equally solve well
Certainly the problem of molding after-contraction deformation.
One embodiment of ultrasonic radar sensor is as shown in fig. 7, the upper cover of ultrasonic radar sensor 3 uses upper layer
The problem of structure of plastics 1 solves welding plastic material shaping and deformation and material cost is caused to rise, and equipment investment rises, modeling
Glue material is alternative more；And the flash after welding can be blocked, keep preferable appearance.
It is emphasized that: the above is only the preferred embodiment of the present utility model, not appoints to the utility model
What formal limitation, any simple modification made by the above technical examples according to the technical essence of the present invention, etc.
With variation and modification, it is still within the scope of the technical solutions of the present invention.
