Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
An embodiment of the present application provides an automatic glue spraying process, and with reference to fig. 1, fig. 1 is a schematic flow diagram of a first embodiment of the automatic glue spraying process.
In this embodiment, the automatic glue spraying process includes:
s10, placing a workpiece on a working table of a glue sprayer;
s20, setting glue spraying parameters based on the glue coating type and the workpiece type, wherein the glue spraying parameters comprise glue spraying air pressure, glue spraying speed, glue spraying time and firing pin stroke;
and S30, starting the glue sprayer, controlling the glue spraying valve body by the glue spraying valve body controller according to a preset glue spraying path, and spraying glue to the workpiece by the glue spraying parameters so as to finish automatic glue spraying of the workpiece.
The research and development background of the application is as follows:
when glue is sprayed on a workpiece, the glue spraying valve body and the firing pin can be continuously replaced, so that the problems of glue overflow, glue unqualified glue and the like caused by different gluing viscosities of different glue coatings and different bonding requirements of different workpieces are avoided, but the glue spraying mode has extremely low efficiency.
Specifically, problems that may arise include: if the gluing viscosity is low and the glue spraying air pressure of the used glue spraying valve body is too high, the glue spraying amount is too high, and if the gluing viscosity is high and the glue spraying air pressure of the used glue spraying valve body is too low, the gluing cannot be normally sprayed; the glue spraying valve body sprays glue to the workpiece according to a preset path, so that glue overflow can be caused if the glue spraying speed is too high or the glue spraying time is too long, and the glue spraying amount can be insufficient if the glue spraying speed is too low or the glue spraying time is too short; if the stroke of the firing pin is too high, the glue output amount may be too large, and conversely, the glue output amount is too small.
Specifically, the types of workpieces are different, and the required glue output amount is different, namely the formed film thicknesses are different; for example, plastic workpieces and aluminum workpieces have different weights and require different thicknesses for bonding, and insufficient thickness may affect the bonding firmness, or uneven thickness may affect the appearance of the bonded product.
The glue spraying machine comprises a glue barrel, a glue spraying valve body controller, a working table top and the like, wherein the glue barrel is used for containing prepared glue, the prepared glue comprises prepared glue with viscosity, performance and the like, and when the glue barrel is subjected to certain glue spraying pressure, the glue inside the glue barrel can be sucked into the glue spraying valve body; spout gluey valve body and be used for right the work piece spouts gluey, spout gluey valve body control and be used for controlling it is right to spout gluey valve body the work piece spouts gluey, table surface is used for placing the work piece of treating the rubber coating.
The glue spraying valve body comprises a nozzle and a firing pin; the firing pin is used for forming instant high pressure through high-speed impact, driving the glue in the glue spraying valve body to be sprayed out from the nozzle to the surface of the workpiece, spraying one glue point every time of impact, and all glue lines are composed of a plurality of glue points.
This application aims at, through spouting gluey parameter based on rubber coating type and work piece type settlement, need not to change and spout gluey valve body or firing pin and can avoid because different gummed viscosity is different, excessive gluey unqualified scheduling problem that bonding requirement inequality of different work pieces leads to improves the efficiency of spouting gluey.
As an example, the glue application types are various, and the glue application for different workpieces is different, for example, the glue application has a performance and a viscosity, for example, the glue application has a better heat resistance and a lower viscosity, and the glue application has a stronger viscosity and a higher viscosity, and the like, and the application is not limited specifically.
Specifically, the workpieces are different in material, size, and the like, for example, the workpieces may be made of a carbon fiber material, a PC (Polycarbonate) plastic, an aluminum material, and the like, and are not limited in particular. The coating applied to different workpieces is different, for example, the coating type applied to carbon fiber materials is MP20-1 injection coating, the aluminum materials are 801 (benzene-free strong adhesion coating), and the like, and specifically, the drawing force of the injection coating of the MP20-1 can reach 150-180N, the viscosity reaches 90-110CPS (Centipoise), and the viscosity is moderate.
The method comprises the following specific steps:
s10, placing a workpiece on a working table of a glue sprayer;
as an example, before the step of placing the workpiece on the working table of the glue sprayer, the operator needs to inject the prepared glue suitable for the workpiece into a glue barrel, and the glue barrel needs to be cleaned and dried to ensure that the glue is free from impurities.
As an example, an operator places a workpiece on a work table of a glue sprayer and performs automatic glue spraying of the workpiece through the glue sprayer.
S20, setting glue spraying parameters based on the glue coating type and the workpiece type, wherein the glue spraying parameters comprise glue spraying air pressure, glue spraying speed, glue spraying time and firing pin stroke;
as an example, the operator sets the glue-spraying parameters in the glue-spraying valve body controller based on the type of the work piece on the current work table and the type of the glue applied to the work piece in the current glue barrel.
Specifically, the glue spraying parameters comprise glue spraying air pressure, glue spraying speed, glue spraying time and striker stroke.
As an example, the operating personnel spouts gluey atmospheric pressure to a definite value through the adjustment to guarantee that this glue barrel's rubber coating can reach smoothly under the effect of this glue pressure of spouting and spout gluey valve body inside, promptly, can not lead to spouting gluey volume too much (spout gluey volume of spouting that gluey valve body inside can load limited because of spouting gluey pressure is too big, or because of spouting gluey pressure undersize, lead to the rubber coating can't reach spout gluey valve body inside.
Specifically, the pressure of the glue spraying is 0.3-0.5 kilopascal.
Specifically, the operator adjusts the glue spraying pressure within the glue spraying pressure range based on the viscosity of the glue.
Specifically, aiming at the injection encapsulation with MP20-1 coating, the workpiece is made of carbon fiber material, and the size of the correspondingly set glue spraying air pressure is 0.5 kilopascal.
As an example, the operator adjusts the glue spraying speed and the glue spraying time to a certain value to avoid glue overflow or uneven glue spraying caused by too high glue spraying speed or too long glue spraying time, or insufficient glue spraying caused by too low glue spraying speed or too short glue spraying time.
Specifically, the excessive glue is caused by the excessive glue spraying amount and the like, so that the glue is applied to exceed the edge of the workpiece.
Specifically, the glue spraying speed is 20-25 mm per second.
Specifically, the operator adjusts the glue spraying speed within the glue spraying speed range based on the viscosity of the glue and the type of the workpiece.
Specifically, aiming at the injection encapsulation with MP20-1 glue coating, the workpiece is made of carbon fiber materials, and the size of the correspondingly set glue spraying speed is 24 millimeters per second.
In this embodiment, the glue spraying time includes an operation time of the glue spraying valve body and a stroke time of the striker, the operation time of the glue spraying valve body includes an open valve time and a closed valve time, and the stroke time of the striker includes a rise time and a fall time.
Specifically, the open time of the glue spraying valve body is 0.3-0.5 milliseconds, and the closed time of the glue spraying valve body is 5.9-6.1 milliseconds.
In this embodiment, specifically, the operator adjusts the size of the glue spraying time within the range of the valve opening time and the valve closing time of the glue spraying valve body based on the size of the viscosity of the glue coating and the type of the workpiece.
Specifically, if the valve opening time of the glue spraying valve body is too long (the valve closing time of the glue spraying valve body is too short), the number of glue dots formed by glue sprayed in the glue spraying valve body is possibly too large, and due to the fact that the glue has certain fluidity and the glue is highly collapsed, the edge of the glue dots is connected, so that the work piece overflows, and the problem of glue overflow is caused. If the valve opening time of the glue spraying valve body is too short (the valve closing time of the glue spraying valve body is too long), the glue discharging amount is possibly insufficient, the glue distribution is not uniform enough, and the problems that a bonded product is not firm and the like are caused finally occur.
Specifically, aiming at the injection encapsulation with MP20-1 glue coating, the workpiece is made of carbon fiber materials, the correspondingly set open time of the glue spraying valve body is 0.3 milliseconds, and the close time of the glue spraying valve body is 6 milliseconds.
Specifically, the rise time of the striker is 0.2 to 0.4 msec, and the fall time of the striker is 0.2 to 0.4 msec.
In this embodiment, the operator adjusts the glue spraying time within the range of the rise time of the striker and the fall time of the striker based on the viscosity of the glue and the type of the workpiece.
Specifically, if the rise time of the striker and the fall time of the striker are too long when the striker travels for a certain time, the impact strength of the striker on the glue coating will be reduced, and the amount of the glue sprayed by the striker is inconsistent with the required amount, and if the rise time of the striker and the fall time of the striker are too short, the impact strength of the striker on the glue coating will be increased, and the amount of the glue sprayed by the striker is inconsistent with the required amount, which may cause problems such as glue overflow.
Specifically, for the injection encapsulation with the coating being MP20-1, the workpiece is made of carbon fiber material, and the corresponding setting is that the rising time of the firing pin is 0.3 ms and the falling time of the firing pin is 0.3 ms.
Specifically, the striker stroke is 50% to 60%.
In this embodiment, the operator adjusts the size of the striker stroke within the striker stroke range based on the size of the viscosity of the glue application and the type of workpiece.
Specifically, through the regulation to the size of striker stroke to the striking dynamics of adjusting the striker, thereby make it and different rubber coating phase-matchs, make the rubber coating homoenergetic of different viscosity spout accurately, specifically, adopt piezoceramics material design drive part, through impulse voltage adjustment striker speed, the striker stroke is accurate controllable.
Specifically, the stroke of the firing pin is the distance from the geometric center of the firing pin to the fulcrum of the glue spraying valve body.
Specifically, the stroke of the striker reflects the moving distance of the striker, and if the rise time and the fall time of the striker are fixed and the striker stroke is too large, the impact force of the striker on the glue spraying is too large, or the striker stroke is too small, the impact force of the striker on the glue spraying is too small, so that the glue spraying amount due to the impact is not consistent with the required glue spraying amount, and the problems of glue overflow and the like may occur.
Specifically, for the injection molding coating with the coating being MP20-1, the workpiece is made of carbon fiber material, and the stroke of the corresponding striker is set to 53%.
Therefore, the glue spraying parameters need to be balanced with each other, and the glue spraying parameters are adjusted based on different glue coating types and workpiece types, so that the problems of glue overflow, unqualified glue and the like caused by different glue coating viscosities and different bonding requirements of different workpieces are solved.
And S30, starting the glue sprayer, controlling the glue spraying valve body by the glue spraying valve body controller according to a preset glue spraying path, and spraying glue to the workpiece by the glue spraying parameters so as to finish automatic glue spraying of the workpiece.
In this embodiment, start spout the machine of glue, spout gluey valve body controller control and spout gluey valve body and spout gluey route according to predetermineeing, and it is right to spout gluey parameter the work piece spouts gluey, promptly, spout gluey atmospheric pressure, spout gluey speed, spout gluey time and firing pin stroke of spouting that set for, spout gluey valve body and spout gluey route according to predetermineeing and spout the work piece and spout gluey, promptly, can accomplish the automation of work piece and spout gluey, spout the work piece after gluey completion and then can not appear overflowing gluey, gelatinoid unqualified scheduling problem.
Specifically, aiming at the injection encapsulation with MP20-1 coating, the workpiece is made of carbon fiber materials, and the glue spraying valve body sprays glue to the workpiece according to a preset glue spraying path and the following parameters: the glue spraying air pressure is 0.5 kilopascal, the glue spraying speed is 24 millimeters per second, the valve opening time of the glue spraying valve body is 0.3 millisecond, the valve closing time of the glue spraying valve body is 6 milliseconds, the rising time of the firing pin is 0.3 millisecond, the falling time of the firing pin is 0.3 millisecond, and the stroke of the firing pin is 53 percent; can avoid overflowing glue, the colloidal unqualified scheduling problem that leads to because different rubber coated viscosity is different, the bonding requirement difference of different work pieces etc. need not to change and spouts gluey valve body and firing pin, has improved and has spouted gluey efficiency to accomplish the automation of work piece and spout gluey.
Specifically, under the same glue spraying parameters, the appearance difference between the plastic and the aluminum sheet is large, the scattered point sawtooth effect is amplified, the glue width and the film thickness are smaller than those of the metal surface on the plastic surface, and therefore the glue spraying parameters need to be adjusted according to different workpiece types.
In the embodiment, compared with the prior art that the glue spraying efficiency is low because the glue spraying valve body and the firing pin are continuously replaced when glue is sprayed on the workpiece, the workpiece is placed on the workbench surface of the glue spraying machine; setting glue spraying parameters based on the glue coating type and the workpiece type, wherein the glue spraying parameters comprise glue spraying air pressure, glue spraying speed, glue spraying time and firing pin stroke; namely, the glue spraying parameters can be set according to different glue application and different requirements of different workpieces on glue spraying, the glue spraying valve body or the firing pin and the like are not required to be replaced, the glue spraying machine is started, the glue spraying valve body is controlled by the glue spraying valve body controller to spray glue according to the preset glue spraying path, the glue spraying parameters are right for the workpieces to spray glue so as to finish automatic glue spraying of the workpieces, the workpieces after glue spraying can meet different glue application requirements, the glue spraying valve body or the firing pin are not required to be replaced, the problems of glue overflow, unqualified glue and the like caused by different glue application requirements and the like due to different glue application viscosities can be avoided, and the glue spraying efficiency is improved.
Further, based on the first embodiment of the present application, another embodiment of the present application is provided, in the present embodiment, since the carbon fiber has a light and thin characteristic, the carbon fiber cannot be formed into a product with a complex structure in a three-dimensional manner at one time, and therefore, in a product field made of a carbon fiber material, bonding between workpieces is required to form a complete product.
In this embodiment, referring to fig. 2, after the step of controlling the glue spraying valve body to spray glue to the workpiece according to a preset glue spraying path and the glue spraying parameter, the method further includes:
s40, moving the workpiece after glue spraying out of the working table, and placing the workpiece in a high-temperature tray for leveling treatment;
in this embodiment, the workpiece after the glue spraying is removed from the workbench surface, and the workpiece is placed in a high-temperature tray for leveling, so that the glue dots can be uniformly attached to the surface of the workpiece, and the leveling needs to be performed for 20-30 minutes.
S50, placing the workpiece after the leveling treatment into an oven for curing treatment;
in this embodiment, the workpiece after the leveling process is placed in an oven for curing, the temperature during the curing process needs to be 80-90 ℃, and the curing process is performed to avoid that when the injection molding machine is used for coating glue in a certain flowing state, the fluidity of the glue coated on the surface of the workpiece is enhanced due to the high temperature state of the injection molding machine, and then the glue overflows the outline of the workpiece.
And S60, placing the workpiece after the curing treatment into an injection molding machine to bond the workpiece and an injection molding piece in the injection molding machine, wherein the injection molding piece is formed by injection molding in the injection molding machine.
In this embodiment, the workpiece after the curing process is placed in an injection molding machine, at this time, the injection molding machine starts to inject the injection molding piece to be bonded, and after the injection molding piece is completely injected, the workpiece and the injection molding piece are bonded in the injection molding machine.
As an example, the injection-molded part is made of a non-carbon fiber material, and the injection-molded part may be made of a PC plastic or aluminum material, and is not limited in particular.
As an example, the workpiece is made of carbon fiber materials, has a simpler structure and can be formed by hot pressing once.
Therefore, in the field of workpieces made of carbon fiber materials, the workpiece made of the carbon fiber materials can be better bonded with the injection molding part by adopting the method.
As an example, the carbon fiber material includes a thermosetting carbon fiber composite material and a thermoplastic carbon fiber composite material, wherein the thermosetting carbon fiber composite material is an oligomer with epoxy groups, mainly epoxy resin, which is formed into a solid with a three-dimensional network structure after being molded, and after being combined with carbon fiber tows, each carbon fiber tow can be well connected into a whole, and the carbon fiber tows have active epoxy groups, hydroxyl groups, ether groups and the like on a chemical structure, so that the carbon fiber tows can be well bonded together, and thus, no fault occurs after the molding.
However, the thermosetting carbon fiber composite material is shaped after injection molding and cannot be melted again, and a workpiece with a complex structure cannot be formed by hot-pressing the thermosetting carbon fiber composite material, so that the bonding method needs to be adopted for the workpiece made of the thermosetting carbon fiber composite material and cannot be hot-pressed to form a complex structure, so as to avoid the loss of the high temperature resistance of the workpiece.
In this embodiment, for a carbon fiber material, especially a thermosetting carbon fiber composite material, the workpiece after glue spraying in this embodiment is removed from the work table, and the workpiece is placed in a high-temperature tray for leveling; putting the workpiece after the leveling treatment into an oven for curing treatment; and (3) putting the workpiece after the curing treatment into an injection molding machine so as to bond the workpiece and the injection molding piece in the injection molding machine, thereby avoiding the loss of the high-temperature resistance of the workpiece to a great extent.
