Wherein the triangles represent the first powder glue 2 and the squares represent the second powder glue 3.
First powder is glued 2 and is glued 3 along vertical interval arrangement at the back of leather 1 with the second powder, and interval arrangement makes first powder glue 2 and second powder glue 3 can distribute at the back of leather 1 uniformly, avoids droing between parcel in-process and the steering wheel.
Alternatively, the first powder glue 2 and the second powder glue 3 may also be arranged at intervals in the transverse direction, or at irregular intervals.
Furthermore, a PU foaming layer is arranged between the leather and the rim portion, the leather is directly bonded with the PU foaming layer, the PU foaming layer is bonded with the rim portion, and the PU foaming layer increases the operation hand feeling of the steering wheel.
Alternatively, the PU foam layer can be replaced by a latex layer, a sponge layer or other elastic layers.
Example two:
in one embodiment of the invention, the steering wheel leather wrapping method comprises the following steps:
pre-coating a first powder adhesive and a second powder adhesive on the back surface of the leather, wherein the melting point of the first powder adhesive is less than that of the second powder adhesive;
heating the leather to a first set temperature, melting the first powdered glue, and then bonding the leather to the steering wheel;
and heating the steering wheel to a second set temperature, wherein the second set temperature is higher than the first set temperature, and melting the second powder glue to further bond the leather and the steering wheel.
As shown in fig. 1, the steering wheel includes an annular rim portion, and the leather 1 needs to be wrapped outside the rim portion to perform decoration and comfort enhancement functions.
Two glues are precoated on the back of the leather 1, namely a first powder glue and a second powder glue respectively, and the first powder glue and the second powder glue are powdery, so that the leather can be sprayed by a machine without manual glue brushing, the leather coating efficiency is improved, and the manufacturing cost is reduced.
Before the leather is bonded with the steering wheel, the leather is heated to a first set temperature, the first set temperature is higher than the melting point of the first powder glue and lower than the melting point of the second powder glue, so that the first powder glue is melted, and the second powder glue is still in a powder state without being melted.
After the first powder glue is melted, the first powder glue is bonded with the steering wheel in advance, and preliminary bonding and fixing of the leather and the steering wheel are achieved.
When the steering wheel is heated to the second set temperature, the second set temperature is higher than the first set temperature and also higher than the melting point of the second powder glue, so that the second powder glue is melted, and the leather is bonded with the steering wheel more firmly.
Preferably, the melting point of the first powder adhesive is 40-60 ℃. The highest melting point of the second powder adhesive is 100-120 ℃.
In some embodiments of the invention, the leather is heated to a first set temperature using a low temperature heat gun.
Because the melting point of the first powder adhesive is low, the first powder adhesive is heated by only using a low-temperature baking gun during coating, the heating time is short, the temperature of the first powder adhesive and the leather is low, workers can conveniently coat the leather on a steering wheel, the problem that the leather is scalded is solved, and the coating efficiency is improved.
In some embodiments of the present invention, when the steering wheel is heated to the second set temperature, the steering wheel is placed in the high temperature chamber for heating.
First powder is glued and can be realized the leather parcel problem, nevertheless is in order to solve steering wheel environmental test requirement, still needs to guarantee that the steering wheel glue can not totally melt under high temperature and lose viscidity and peel off. Therefore, the second powder adhesive is compounded on the back of the leather, and the existing coating process is optimized.
When heated to the second set temperature, the second set temperature may cause the first powder adhesive to decrease in viscosity. The second powder glue can not lose viscosity and peel off at the second set temperature, so that the leather is bonded with the steering wheel more firmly.
Further, the first powder adhesive and the second powder adhesive are hot melt adhesives.
The first powder adhesive and the second powder adhesive can be the existing conventional hot melt adhesive, and the first powder adhesive and the second powder adhesive cannot react with each other.
The first powder glue and the second powder glue may be of the type PA/PES/TPU, etc.
In some embodiments of the present invention, the first powder adhesive and the second powder adhesive may also be special hot melt adhesives, when the second powder adhesive is melted, the first powder adhesive is also melted, and a polymerization reaction occurs between the first powder adhesive and the second powder adhesive, so as to form an adhesive with stronger adhesive force.
In some embodiments of the present invention, before heating the leather to the first set temperature, the method further comprises the following steps:
cutting the leather into leather sheets;
sewing the leather sheets into leather rings;
the leather ring is sleeved on the steering wheel.
The first and second powdered glues are coated on the whole leather, and before heating, the first and second powdered glues are non-adhesive. Then cutting the whole leather to make several leather sheets, sewing them into leather ring, finally covering the steering wheel with leather ring.
Further, the step of heating the steering wheel to a second set temperature is preceded by sewing the apron. At the moment, the leather collar is coated and bonded with the steering wheel through the melted first powder glue, and then the tail end of the leather collar is sewn with the leather collar, so that the leather collar is completely coated on the rim part of the steering wheel.
And finally, heating the steering wheel to a second set temperature to further firmly adhere the back surface of the leather collar and the steering wheel.
As shown in fig. 4, a steering wheel leather wrapping method in a preferred embodiment of the present invention includes the steps of:
step 01: pre-coating a first powder adhesive and a second powder adhesive on the back surface of the leather, wherein the melting point of the first powder adhesive is less than that of the second powder adhesive;
step 02: cutting the leather into leather sheets;
step 03: sewing the leather sheets into leather rings;
step 04: sleeving a leather ring on a steering wheel;
step 05: heating the leather to a first set temperature, melting the first powdered glue, and then bonding the leather ring to the steering wheel;
step 06: sewing the leather collar;
step 07: and heating the steering wheel to a second set temperature, wherein the second set temperature is higher than the first set temperature, and melting the second powder glue to further bond the leather collar and the steering wheel.
The embodiment not only meets the leather coating process of the steering wheel, but also meets the solution of the harsh environmental experiment requirement of the automobile steering wheel:
1) in order to solve the problem of leather coating, a first powder adhesive with low melting point is compounded on the back surface of leather. Because the melting point of the first powder adhesive is low, the glue is heated only by using a low-temperature hot drying gun during coating, the heating time is short, the temperatures of the glue and the leather are low, workers can conveniently coat the leather on a PU foaming layer of the steering wheel, the problem that the leather is scalded is solved, and the coating efficiency is improved.
2) In order to meet the requirements of steering wheel environment experiments, the requirement that the steering wheel is stripped because glue is not completely melted and loses viscosity at high temperature needs to be guaranteed, so that a second powder glue is compounded on the back of leather, and the existing coating process is optimized.
3) Because the first powder adhesive and the second powder adhesive are introduced, manual glue brushing is not needed, the leather coating efficiency is improved, and the manufacturing cost is greatly reduced.
The foregoing is considered as illustrative only of the principles and preferred embodiments of the invention.
