Definitions

  • the present invention relates to a method for a printing block and a printing block for pad printing of an electrically conductive image on a component, preferably a mobile telephone cover.
  • an object of the present invention is to eliminate the disadvantages that are present with the above mentioned constructions by adapting the shape of the printing block according to the shape of the pad, which in turn is adapted to the shape of the component, which can be equipped with concave, convex and angled surfaces, so that at least one connecting side of the component can be printed at the same time.
  • the printing block By providing ducts to the printing block, which ducts remove gatherings of air at the corners of the component and other cavities, the printing block can no longer be prevented from transferring colour to the pad in said hard-to-reach places.
  • the printing block can, for example, be flat, concave, convex or combinations of these shapes.
  • These parts are, according to the invention, solidly or movably applied to each other to form a complete printing block.
  • This can, according to the invention, in at least one of its parts, present at least one corner or at least one radius in its surface, which is formed by at least two sides angled to each other.
  • a scraper is used which is led across this, so that a predetermined amount of colour is put in an at least one depression present on the printing block, so that an image is created.
  • Another way of transferring colour to the pad is carried out so that the pad, which is soft, when pressed down is flattened against the bottom of the formed printing block so that a counter-pressure is formed in this, which in turn causes a deformation of the pad, whereby this then expands in another direction, whereby it touches at least one angled and/or curved side of the printing block, which side is covered with colour, whereby this is transferred to the pad.
  • Via at least one duct and/or at least one hole, leading from a corner, present in connection with the printing block a gathering of air formed at this corner is carried off, which gathering of air is created when the pad is being pressed down against the printing block. This prevents the colour from lying in corners and other hard-to-reach places of the printing block.
  • the colour is first collected from a printing block, which has curved, but not movable sides, which colour has been applied to the printing block and scraped out, so that a predetermined image has been achieved.
  • the printing block has a form which is adapted to the shape of the pad.
  • the scraper which flattens the colour on the printing block, has the ability to follow the irregular surface of the printing block since its mounting is flexible. This can be secured to an axle, so that it can pendulate with a predetermined movement or it can be movably secured in a track which follows the formation of the printing block.
  • the pad can perform a rotary movement over the printing block, at which firstly the side is laid against the printing block so that it is provided with colour. Thereafter the rotary movement of the pad continues with continuous contact with the printing block, so that the application angle towards this is changed continuously, at which the rest of the image sticks to the pad.
  • the printing block is equipped with movable boundary surfaces, which can assume a position which makes the whole printing block flat when the colour is applied, at which the scraper then moves across its entire surface, to press colour into the stamping of the printing block.
  • the printing block according to the invention in the preferred embodiment is built up mainly as a box, provided with a mainly flat bottom. To this, for example four mainly vertical sides connect. When the scraper scrapes the colour in the etched depressions of the printing block, the sides and the bottom of the printing block lie flat.
  • the sides are put in a mainly vertical position.
  • the pad now collects the colour from the printing block in three steps. Firstly, the image is delivered from the bottom of the printing block by means of the pressure of the pad. In step two, a continued compression of the pad deforms a bottom surface present on the pad, at which this deformation propagates through the pad, so that at least one existing side thereof comes into contact with the mainly vertical sides of the printing block, at which these also deliver colour to the pad. According to the invention, in step three, the corners of the pad will be pressed into the corners of the printing block.
  • Fig. 1 shows a schematic perspective view of a flat printing block with an applied image according to the present invention, which is built up of partial printing blocks,
  • Fig. 2 shows a schematic perspective view of a printing block formed according to a pad, before the pad collects the image
  • Fig. 3 shows a sectional view of a printing block in a resilient material, which is formed according to the shape of the pad, before the pad collects the image
  • Fig. 4 shows a view of a rotating wheel with a plurality of printing blocks and a section through one of the printing blocks
  • Fig. 5 shows a schematic perspective view of a section through a printing block, which mainly resembles a box provided with air- venting holes.
  • the device according to the invention comprises a printing block 1, which is in step 1 of a pad printing method, which printing block presents a plurality of partial printing blocks 2, which are mainly flat, which are movably connected to each other by means of a hinge function 3, which makes it possible to rotate the partial printing blocks upwards around the hinge function 3 in a rotational direction 4.
  • a slit 6 is made in the printing block 1, to make it possible to fold the partial printing blocks 2 upwards.
  • Colour 5 is applied with a scraper so that the image 5 has been created in a depression present in the printing block 1, at which for example certain recesses 7 are positioned at chosen places.
  • the image 5 is an electrically conductive layer, which is to be collected by a pad and then pad printed onto the inner side of a mobile telephone cover.
  • the recesses 7 consist of holes in the layer to give room for buttons, speaker, antenna, contacts etc. present in a mobile telephone.
  • the printing block 1 according to Fig. 1 is in stage 2 of the pad printing method, at which the partial printing blocks 2 have been folded upwards around the hinge function 3 by a mechanism, which mechanically via devices 10 preferably connected to at least one partial printing block 2, is capable of actuating these, so that they assume a mainly upright position, at which the printing block 1 mainly resembles a box.
  • a mechanism which mechanically via devices 10 preferably connected to at least one partial printing block 2
  • the printing block 1 mainly resembles a box.
  • the partial printing block 2 also having a somewhat angled position, so that it does not stand entirely upright.
  • the pad which mainly is formed like the inner side of the mobile telephone cover, can collect the image 5 from the printing block 1, at which the sides 8 and the bottom 9 of the image are collected, to then be pad printed onto the inner side of the mobile telephone cover.
  • the printing block 1 is built up of a resilient material, such as metal sheet, which by means of the devices 10 has assumed a position, so that the printing block 1 in at least one place presents a curved side 30 or an angled side 8 according to Fig. 2.
  • a resilient material such as metal sheet
  • the colour has been applied in a flat position according to step 1 above. If the printing block is permanently formed, so that it is not movable, the image 5 cannot be applied according to what is described in Fig. 1.
  • the scraper 11 must be able to move so that it is in contact with the printing block all the time according to a predetermined pattern of movement, so that the colour has the possibility of being scraped out over the entire printing block, even if it presents a plurality of angled and/or curved sides.
  • a distance, which consists of a stretch 12 from the surface of the printing block 1 to a fastening point 18 on an arm 13 existing on the scraper 11, must therefore be adapted together with an application angle 14, so that at least one leg 16 on the scraper, during the movement of the scraper 11, is always capable of pressing the colour against a hollow 17 of the printing block, so that it, during its entire pattern of movement, abuts against the printing block.
  • the arm 13 is mov-ably secured in a guide rail 19, which in turn is secured somewhere on a pad printing machine used for the pad printing method.
  • the guide rail 19 at least one guide field 20 is applied in the form of at least of one track formation or similar, the effect of which is that the scraper can perform a predetermined movement.
  • the arm 13 can be provided with one additional fastening point 21 , which is also movably secured to the guide rail 19, so that the arm 13, when moving along the guide rail 19, can change its application angle 14.
  • the printing block 1 can be provided with partial printing blocks 26 on the sides, which are movably or permanently applied on the printing block 1, according to what is mentioned above in Figs. 1 and 2.
  • the scraper 11 can then be supplemented so that it also scrapes colour into depressions 17, which are present in the partial printing blocks 26, to create an image 5 in these places as well. In this way it becomes possible to provide a pad with colour on more than one side.
  • a rotating wheel 27 which presents a plurality of printing blocks 22 applied in the area at the periphery of the wheel 27, which wheel 27 is applied onto an axle 23, so that it is able to rotate in a direction 24.
  • a scraper 11 is to apply colour so that an image 5 is created on the printing blocks 22 in a continuous process, i.e. each printing block, one after the other, is provided with the image 5 in the manner described according to Fig. 3, with the exception that, since the wheel 27 is rotating, the scraper 11 does not need to move according to a guide field 20.
  • the application angle 14 and/or the distance 12 need to be able to vary during the rotation.
  • the printing block shown in Fig. 5 it is equipped with four sides 8, which are in a mainly upright position, so that comers are formed in the printing block.
  • a pad is to collect an image 5 applied to the printing block 1.
  • an air volume present in the printing block is compressed, at which this can escape through holes 29 present in the comers, at which the pad will be able to collect the entire image 5, also in the comers of the printing block 1.
  • the expression "complementary fit" will be used to describe the shape of the printing block relative to the pad. Naturally, this shape refers to the inverted shape of the pad.
  • the printing block has a box-like shape, in which the brick (the pad) can be immersed.
  • the inside of the box (the printing block) has a complementary shape in relation to the brick (the pad).
