Description
Technical Field
The invention relates to the technical field of die cutting, in particular to a preparation method of a composite piece for electronic equipment.
Background
In the production of auxiliary materials for industrial electronic devices, a large number of components are produced by die cutting, and the raw materials for die cutting, such as Polyimide (PI) tapes (films) for high-temperature insulation, Polyester (PET) tapes (films), high-low viscosity and self-adhesive protective films in high-purity PET for surface protection, become thinner and thinner with the advance of science and technology, and these soft thin materials are usually required to be compounded and then formed into a composite piece and then subjected to die cutting, for example, the soft thin materials are required to be compounded with double-sided adhesive and then further processed.
The existing composite equipment is usually designed for the original material with large thickness, when the thickness of the soft thin material is smaller and smaller, for example, the thickness is less than 0.1mm, because the strength of the soft thin material is difficult to provide support, the soft thin material is not easy to be in line or in plane to operate the material, and the problems of air bubbles, deformation, wrinkles, irregularity and the like are easy to generate in the composite process, so that the product after composite is unqualified.
Because these soft and thin materials usually have a certain elasticity, if they are simply flattened by external force such as mechanical force, and after the materials such as double-sided adhesive tape are compounded, the compounded product is easily curled or even has a large size change due to the internal stress of the materials themselves. Thereby causing the unqualified product after compounding.
In the existing processing technology, some manufacturers use a servo motor and a tension sensor to control the material receiving and discharging of the soft thin material in the process of flattening the soft thin material by means of external forces such as mechanical force and the like, so that the inner stress of the soft thin material is controlled while the soft thin material is kept flat in the compounding process. However, since the adjustment method belongs to the post-type feedback control, that is, the speed of the material receiving and discharging needs to be controlled after the change of the stress of the soft thin material is detected, and the process is continuous, when the stress of the soft thin material with a very thin thickness (for example, less than 0.1mm) changes, the size of the material is affected, so that the size of the composite product fluctuates, and the quality stability of the composite product is difficult to ensure.

Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
FIG. 1 is a schematic diagram of a method of making a composite for an electronic device according to an embodiment of the present invention; the direction of travel of the material is indicated by the arrows in the figure. Fig. 2 is a schematic perspective view of the blowing module of fig. 1. Referring to fig. 1-2, the present invention provides a method for preparing a composite member for an electronic device, which is used for compounding a single layer of a soft and thin material 100 with a double-sided tape 200, comprising the steps of:
providing a feeding module 1, wherein the feeding module 1 comprises at least two carrier rollers 12 and a conveying belt 11 which is carried by the carrier rollers 12 and can rotate circularly, a material roll 101 of the soft thin material 100 is arranged above the rear side in the conveying belt 11 to ensure that the soft thin material 100 can fall on the conveying belt 11 when naturally falling, an adhesive roller 2 is arranged on one side of the carrier rollers in the horizontal conveying direction of the conveying belt 11, the distance between the adhesive roller 2 and the conveying belt 11 is equal to the thickness of the soft thin material 100, a feeding roller 3 for conveying the double-sided adhesive 200 is arranged right below the adhesive roller 2, a blowing module 4 which can rotate and can move along the direction parallel to the plane of the axes of the two carrier rollers 12 is arranged above the feeding module 11, and a blowing module which can rotate and can move along the direction parallel to the plane of the axes of the two carrier rollers 12 is arranged between the material roll 101 and the conveying belt 11, The linear speeds of the adhesive roller 2 and the feeding roller 3 are kept consistent, the blowing module 4 is directed to the conveying belt 11 at the side close to the adhesive roller 2, then the material is discharged from the material roll 101, the soft thin material 100 is naturally dropped and attached to the conveying belt 1, the attachment of the soft thin material 100 to the conveying belt 11 is kept until the soft thin material 100 is adsorbed by the adhesive roller 2, at this time, the blowing module 4 is started, the blown gas is blown to the conveying belt 11, then the blowing module 4 is rotated until the blown gas is parallel to the plane where the axes of the two carrier rollers 12 are located, and the soft thin material 100 naturally dropped between the material roll 101 and the conveying belt 11 is in a natural tension state, so that the soft thin material 100 attached to the conveying belt 11 can be kept flat and almost free of internal stress, after the flat soft thin material 100 is adsorbed by the adhesive roller 2, the flat soft thin material is compounded with the double-sided adhesive tape 200 conveyed by the feed roller 3 between the adhesive roller 2 and the feed roller 3, so that a compound product is obtained.
In the present invention, the conveyor belt 11 and the blowing module 4 which can rotate circularly are arranged to ensure the flatness and stress relief of the soft thin material 100 before being compounded, and specifically, the conveyor belt 11 has a smooth surface, such as a smooth stainless steel belt, with a surface roughness Ra of less than 0.2, so that the soft thin material 100 can move freely in a stretching manner when being attached to the conveyor belt 11, and thus the self-deformation stress can be relieved.
The blowing module 4 may be a rectangular outlet connected with a blower (not shown), as long as the ultrathin material 100 can be covered in the width direction.
When the soft and thin material 100 starts to combine with the double-sided adhesive tape 200 between the adhesive roller 2 and the feeding roller 3, the soft and thin material 100 is subjected to a combination force, at this time, the blowing module 4 is started (the position shown by the dotted line in fig. 1), the blown gas is blown towards the conveyor belt 11, then the blowing module 4 is rotated until the blown gas is parallel to the plane of the axes of the two carrier rollers 12, in the process, the gas blown by the blowing module 4 firstly flattens the soft and thin material 100 on the conveyor belt 11, and extrudes air which is possibly wrapped between the soft and thin material 100 and the conveyor belt 11, and then, when the blown gas is parallel to the plane of the axes of the two carrier rollers 12, the gas flow sent by the blowing module 4 can make the soft and thin material 100 which naturally hangs down between the conveyor belt 101 and the conveyor belt 11 in a natural tensioning state, therefore, the soft thin material 100 can be attached to the conveyor belt 11 without air bubbles, and the soft thin material 100 in a natural tension state can be attached to the conveyor belt 11 without deformation stress.
The air volume of the air flow sent out by the blowing module 4 can be adjusted according to specific situations, for example, the total weight of the soft and thin material 100 in the natural falling section can be calculated, and then according to the area of the air outlet of the blowing module 4, the flow rate when the acting force of the air flow on the soft and thin material 100 is calculated and obtained as long as the acting force is 1.2-1.5 times larger than the total weight of the soft and thin material 100 in the natural falling section, so that the air volume of the air flow sent out by the blowing module 4 can be controlled as long as the soft and thin material 100 in the natural falling section can be kept in a natural tensioning state.
The blowing module 4 can move along the direction parallel to the plane of the axes of the two carrier rollers 12, so that the position of the blowing module 4 can be adjusted by translation during the production process to adjust the wind force to which the soft thin material 100 is subjected.
Of course, as shown in fig. 2, the blowing module 4 may also be provided with a downward air outlet, and by controlling the downward air outlet, a part of the air flow can be blown to the conveyor belt 11 when needed, so as to ensure that the soft thin material 100 does not wrap air and generate air bubbles when being attached to the conveyor belt 11 during the operation of the apparatus.
The blowing module 4 may be connected to a plasma wind device (not shown), so that the air flow sent by the blowing module 4 is plasma wind, thereby preventing the soft and thin material 100 from being deformed due to electrostatic influence.
Of course, the feeding module 1, the material roll 101 and the blowing module 4 may be disposed in a semi-closed housing (not shown), so that a humidifier or the like capable of maintaining air humidity may be disposed in the housing, thereby preventing static electricity from being generated in the apparatus and the soft thin material 100.
The adhesive roller 2 may be a device used for adsorbing the soft thin material 100 in an existing production process, and for example, may be a roller coated with a self-adsorbing coating on the surface thereof, as long as the soft thin material 100 can be adsorbed.
The distance between the adhesive roller 2 and the conveyor belt 11 is equal to the thickness of the soft thin material 100, that is, the gap between the adhesive roller 2 and the conveyor belt 1 is controlled within a range with a small deviation from the thickness of the soft thin material 100, for example, when the thickness of the soft thin material 100 is 0.1mm, the distance (i.e., the gap) between the adhesive roller 2 and the conveyor belt 11 can be set to 0.1 ± 0.03mm, so that the adhesive roller 2 can absorb the soft thin material 100 conveyed by the conveyor belt 11 without additional external mechanical force, the soft thin material 100 moves along with the adhesive roller 2, the soft thin material 100 has no internal stress, and no air bubbles exist between the soft thin material 100 and the adhesive roller 2.
The distance between the adhesive roller 2 and the feeding roller 3 is equal to the sum of the thicknesses of the soft thin material 100 and the double-sided adhesive tape 200, that is, the gap between the adhesive roller 2 and the feeding roller 3 is controlled within a range with a small deviation from the sum of the thicknesses of the soft thin material 100 and the double-sided adhesive tape 200, for example, when the thickness of the soft thin material 100 is 0.1mm and the thickness of the double-sided adhesive tape 200 is 0.3mm, the distance (i.e., the gap) between the adhesive roller 2 and the feeding roller 3 can be set to 0.4 ± 0.03mm, so that the soft thin material 100 and the double-sided adhesive tape 200 can be ensured to be free from stress, and the quality of a compounded product can be effectively ensured.
Referring to fig. 1, the axes of the carrier roller 12 and the adhesive roller 2 of the feeding module 1 may be on a horizontal plane, the axes of the carrier roller 12 and the material roll 101 on the left side of the feeding module 1 may be on a vertical plane, and the axes of the adhesive roller 2 and the feeding roller 3 may be on a vertical plane, so as to facilitate the arrangement of the positions of the components in the actual production.
The minimum distance of the axis of the roll 101 from the conveyor belt 11 is greater than twice the maximum diameter of the roll 101. This ensures that a sufficient length of the soft thin material 100 in the naturally hanging state can be tensioned by the air flow sent out by the blowing module 4, thereby eliminating the internal stress to the maximum extent.
When each material roll 101 starts to discharge, the soft thin material 100 can be assisted to be attached to the conveyor belt 11 manually or by other tools until the soft thin material 100 is adsorbed by the adhesive roller 2.
The preparation method of the composite part for the electronic equipment can fully eliminate the internal stress and deformation of the soft and thin material before compounding, thereby greatly improving the yield of the composite part product and improving the production efficiency.
