Řízení modelu dávkování lepidla / Control system for glue dispensing application model

Šimurda, Jan January 2016 (has links)
This thesis addresses the problematics of automated mini-doses application of the adhesive. In thesis are summarized the parameters and types of adhesives with regard to the suitability and the basic theory of bonding. At the same time are summarized the available technologies and methods of bonding. Part of the work is the analysis of requirements for automatic microdosing, in terms of management, delivery system, manipulator, mechanics, functional safety. It also includes the selection of suitable components. The thesis contains the development and description of the control software, visualization, data acquisition, management of robotic manipulator, functional safety logics and dispenser management. The outcome of the thesis is a functional device according to the proposed 3D model made of borrowed components on which algorithms are tested and functionality was verified. In the conclusions are described the complementary features ensuring the possibility of setting the device up in the industry.

Optimalizace lepení střechy autobusu / Optimalization of bus roof glueing

Jaroš, Vojtěch January 2012 (has links)
The main object of this master´s thesis is to increase productivity glueing and lowering the weight of the bus roof while maintaining its toughness. The first part describes the present glueing technologies. Subsequently, there is adduced theoretically various hypothesis about the glue seam. The proposed solution is to use the glue containing accelerators. Two glues from the companies DINITROL and SIKA are suggested and compared. The following chapter details the suggested technology and describes its possibilities. The final part presents the project of ultralight roof made from sandwich panels.

Stark, starkare, starkast : en jämförelse av fasta tappar och centrumtappar med utgångspunkt i tappens dimensioner, inpassning, komprimering, antal och limning / Optimizing the stability : an investigation of tenon and dowel joints regarding their dimensions, fitting, compression, number and glueing

Berglund, Jonas January 2018 (has links)
I mitt examensarbete jämför jag styrkan för sammanfogningar i trämöbler med fasta tappar och centrumtappar utifrån fem parametrar: tappens dimensioner, tappens inpassning, tappens komprimering, tappens antal och tappens limning. Den övergripande frågan har varit, ”är fasta tappar eller centrumtappar starkast?” Målet har varit att sålla i olika teorier rörande dessa två typer av sammanfogningar och skapa ett underlag i syfte att hjälpa möbelsnickare och formgivare att kunna ta medvetna beslut vad gäller sina val av dessa typer av sammanfogningar. Genom litteraturstudier och verkstads besök har jag samlat kunskap som ligger till grund för det hållfasthets test jag sedan gjort i materiallabbet på Linköpings universitet. Testet har utgått från ett scenario där en stols bakben ska fogas samman med en sarg. Testet visar, utifrån ett antal angivna avgränsningar, att fasta tappar utan undantag är starkare än centrumtappar.Det visar också att en dubbel fast tapp fördelar belastningen bättre än en enkel fast tapp och bidrar till en betydligt starkare fog. För c-tappar gäller generellt att ökat antal tappar ökar fogens seghet men inte nödvändigtvis maxbelastningen. Inpassning och komprimering har betydelse för hur seg en fog är. / I have in my thesis compared the strength of mortise and tenon joints and dowel joints in wooden furniture. I´ve made the comparison based on five parameters: the dimensions of the tenon or dowel, the fit of the tenon or dowel, the compression of the tenon or dowel, the number of tenons or dowels and the gluing of the tenon or dowel. The bigger question has been, “is the mortise and tenon joint or the dowel joint the strongest?” The goal has been to go through different theories regarding these two types of joinery and making a foundation to help cabinet makers and designers to make conscious decisions regarding their choices of these two types of joinery. Through studies of literature and visiting workshops I´ve gathered knowledge that lies as a foundation for a test of strength of different joinery made in the material testing facility of Linköping University. The test was based on a scenario of joining the back leg and side rim of a chair. The test shows, from the given definitions, that mortise and tenon joints are without exceptions stronger than dowel joints. It also shows that double tenons better will distribute the load and make for a stronger and tougher joint. Dowel joints will get tougher with an increased number of dowels but it will not necessarily make for a stronger joint. The fit and compression of the tenon or dowel will affect the joints strength.

Virtuální zprovoznění robotizovaného pracoviště pro nanášení lepidla / Virtual commissioning of the robotized workplace for glue application

Radil, Filip January 2020 (has links)
This diploma thesis deals with the design and virtual commissioning of a robotic workplace designed for glueing and assembling a car headlight. The thesis contains a summary of available information on the matter of virtual commissioning and industrial robotics. It also contains a system analysis of the necessary equipment, followed by a design of several workplace variants. The final solution for which the 3D model is made is selected from them. With it, in the RobotStudio software, a simulation of all processes taking place at the workplace is created. On its base, a control program is created and debugged, and virtual commissioning of the workplace is performed.
