Definitions

  • the invention relates to a method and a device for labeling parts manufactured in a work line, as well as a laser cell therefor.
  • the clear identification of parts is of great importance for tracing the production of parts today.
  • the parts are usually labeled directly using a laser.
  • the label typically includes a serial number, the date and the manufacturer, so that the production process, for example the batch of a part, can be easily traced.
  • Such a method and such a device are known from DE 27 26 454, for example.
  • the parts between an inspection body and the marking body are divided into zones of the length of the marking to be affixed. Every single zone between the inspection body and the marking body is tracked electronically. The surface of each tracked zone is oxidized and melted by a laser light source.
  • the object of the invention is to develop a method and a device for labeling parts manufactured in a work line and a laser unit for use in such a method and / or such a device in such a way that the production and the labeling run more efficiently.
  • An essential idea of the invention is to label and prepare ready-to-use parts that were produced in a work line and are on a carrier part either immediately or indirectly after their production.
  • the parts should remain on the carrier strip.
  • the labeling process can be carried out as soon as possible after the production process of the parts, so as to enable labeling "on the fly”.
  • high throughput speeds can be achieved in the production of parts, in particular mass parts such as contacts for connectors.
  • the parts are wound onto a spool immediately after the production process, stored temporarily and then fed from the spool to the labeling process.
  • the invention relates to a method for labeling parts, the parts being produced in the form of a tape from a drive device directly or indirectly to a labeling device, counted, labeled and wound onto a spool by a winding device.
  • the advantage of this method is, in particular, that the parts can remain on their carrier tape immediately after their production, this carrier tape is also used for the labeling process, and the parts together with their carrier tape are then wound onto a spool ready for further processing.
  • the coil with the labeled parts can then be further processed immediately, for example used in a pick and place machine that uses the labeled parts to populate any other components.
  • a typical application example is the production of electrical connectors that have contacts. The contacts are labeled for traceability and mass parts that are produced on the line by a machine.
  • the parts are preferably produced by punching from a material strip.
  • the parts e.g. B. Contacts remain on the material tape and can thus be supplied as a continuous contact material to the labeling device. This is advantageous in the production of mass parts, such as endless contact material, since the labeling process can be carried out with a significantly shorter time span. But it can also be parts that are made after a further process, e.g. B. after overmolding, galvanic finishing and the like to be labeled in one go.
  • the labeling device comprises a laser that labels the parts under the control of a computer.
  • a laser has the advantage that it can be labeled at a very high speed.
  • the typical labeling time of a small part can be carried out in just 23 ms, for example. Due to the continuous feeding of the parts to the laser, the labeling process can be carried out directly after the production of the parts without a great delay.
  • all parts that are wound on a common spool are each labeled with a code that uniquely identifies the common spool.
  • This code is particularly important for tracing parts. It shows which spool a part comes from. This helps determine which machine made the part and when the part was labeled. This makes tracing much easier.
  • a marking which is applied at a defined time, can trigger a change of a spool in the band with labeled parts.
  • the marker serves as a kind of external trigger that triggers a coil change.
  • an internal trigger in the form of a counter can be provided, which triggers the ones that have already been wound onto a coil Parts counts and triggers a coil change when a certain counter reading is reached.
  • the marking is preferably formed by a missing part in the band with labeled parts. If a light barrier is used to detect the parts, the missing part in the belt can be quickly and easily detected by the light barrier. Any other type of marking could also be used. B. by a graphic marking of a part more difficult to detect than the missing part.
  • a control section When changing the bobbin, a control section can be separated from the strip with labeled parts, on which there is a first part with a label for a first coil and a second part with a label for a second coil inserted after the first.
  • This control section can be used, for example, to document a successful spool change. He can also prove the correct change of labeling when changing from one spool to another.
  • the invention further relates to a device for labeling parts, with a drive device for moving and guiding a tape with parts and a labeling device for counting and labeling the parts and a winding device for winding the labeled parts onto a spool.
  • the belt with parts can be fed to this device, for example, directly after its production.
  • the tape can also be reeled from a manufacturer of the parts are delivered and inserted into the device, which then unwinds the tape with the parts from the spool via the drive device, inscribes them and winds them up again on a spool.
  • the device according to the invention can be used to offer a service such as “marking parts” which are supplied as a tape on a spool.
  • the device according to the invention can also be preceded by a device for producing the parts.
  • a device for producing the parts can be manufactured in a kind of integrated manufacturing process and delivered as coil goods.
  • the device for producing the parts is, for example, a punching device with which the parts can be punched out of a material band and then remain on the carrier strip for further transport.
  • the labeling device preferably comprises a laser and a computer, the computer being set up in terms of program technology to control the laser in such a way that it can label the parts.
  • Marking can also be done using a marking tool. Depending on this marking, a bobbin change is carried out during winding.
  • a separating device can also be provided, which is designed in such a way that when a coil is changed from the strip of labeled parts, a control section is separated, on which a first part with a label for a first coil and a second part with a Labeling for a second, after the first coil inserted.
  • a camera inspection system is provided which is designed for the optical inspection of the parts.
  • the camera inspection system is provided in front of the labeling device in order to check the parts to be labeled.
  • the invention relates to a laser cell which is designed for use in a method according to the invention and / or a device according to the invention as a labeling device and a housing, a tape drive with a control, a tape guide, a trigger light barrier, a microcontroller control and has a laser.
  • the laser cell comprises a computer which is set up in terms of program technology to control the laser.
  • the computer is preferably a personal computer which is set up in terms of program technology in order to be able to set a labeling process via a user interface.
  • the laser cell can comprise a marking device which is designed to mark a strip with parts for a reel change.
  • it can also include at least one camera inspection system for inspecting parts.
  • the device preferably comprises two camera inspection systems; a first camera inspection system is arranged for checking parts before the inscription and a second camera inspection system is arranged for inspecting parts after the inscription.
  • the first camera inspection system checks e.g. the parts to be labeled and can prevent bad parts from being labeled.
  • the second camera system checks e.g. the labeled parts as to whether they have been labeled correctly.
  • FIG. 1 shows a device 30 for producing parts 34 in the form of a band 32.
  • the tape 32 is fed from a conveyor device 36 forming part of a laser unit 22 to an inscription device 38, ie is drawn.
  • the labeling device 38 labels the parts 34 with a laser.
  • the tape 32 with the labeled parts 42 is transported further to a winding device 40, the tape 32 with the labeled parts 42 on a spool 44 wound up.
  • the coil 44 can now be used directly for further processing of the labeled parts 42. It is essential in the device shown that the parts 34 are labeled in the so-called "on the fly" mode of operation immediately after the production of the parts 34 and without causing delays in the manufacture, labeling and winding of the parts 34 and 42, respectively a coil 44 comes.
  • Fig. 2 shows a strip 10 with parts 12, which has been produced for example by a punching device from a sheet metal strip.
  • the parts 12 can be used for example contacts.
  • the tape 10 with the parts 12 is fed to a labeling device (not shown) immediately after its production.
  • the parts of a coil - N - are labeled with a code A and the parts of the next coil - N + 1 - with a code B.
  • the code A or B contains the coil number, see Figure 2.
  • the labeling is done by means of a laser, as will be described in detail below.
  • the coils can be used in production, for example to provide connectors with contacts.
  • each coil can accommodate 4500 parts. Then the bobbin is full and must be replaced. The process of changing the bobbin is explained in detail below, but will be discussed briefly here.
  • the tape 10 with the parts 12 has a cut-off, that is to say nonexistent part 13 as a mark for changing the bobbin (shown in dashed lines in FIG. 2). This cut or non-existent part 13 can be evaluated by a detection device in such a way that it generates a signal for changing the coil.
  • a partial cutout for checking 14 is separated out of the band 10 when the reel is changed.
  • This partial section 14 comprises two labeled parts 12.
  • a part 12 is the last part of the coil with the number N and is labeled with the code A.
  • the part 12 has the part number 4501.
  • the second part 12 is the first part of the following reel with the number N + 1 and bears the code B as its inscription. Its part number is 0.
  • the two parts 12 contained in the control cutout 14 become exclusively a review of the labeling of the parts used and therefore do not reach the coils N and N + 1.
  • the labeling or code of the parts 12 can include the date and manufacturer information. Any other information can of course be applied to the parts 12.
  • the code itself can be, for example, a system number, the date of manufacture and how already mentioned the coil number may be dependent. It is essential that there are no parts 12 with code A on the spool with number N + 1 and no parts 12 with code B on the spool with number N.
  • the above-mentioned marking, which is applied when changing the bobbin, can be recognized by the winding device, so that it performs a bobbin change.
  • the parts 12 of the tape 10 are labeled "on the fly". This means that the tape 10 or a strip with the parts 12 does not have to be stopped separately for labeling. Instead, the labeling in the labeling device can be carried out in a continuous pass immediately after the parts have been produced. As a result, the drive of the belt 10 does not have to be started and stopped constantly, which can lead to vibrations of the belt 10. This enables a higher throughput rate to be achieved since the dead time for the transport of the parts 12 of the belt 10 is eliminated.
  • the labeling device can comprise a laser cell, the labeling laser with a PC, a controller unit, a trigger light barrier, a drive system, a marking module, electrical accessories such as power supply, buttons, relays, lights, cabling, etc., a housing of the cell with a mechanical structure such as profiles, strip guides, brackets, ventilation, radiation protection etc. and an optional camera system for checking the parts 12 includes.
  • the marking laser can be of the VMC3 type from Trumpf and can comprise a supply device, an optical unit, a monitor, a keyboard and a mouse. Interfaces and a personal computer with which the laser is controlled are preferably accommodated in the supply device.
  • the personal computer (PC) is therefore referred to below as a laser PC.
  • a controller unit from Vester Elektronik GmbH can be used to count and monitor parts 12 and to control time-critical processes in real time.
  • This controller unit is referred to as controller in the following.
  • the controller can be connected to the laser PC using an X20 interface connector.
  • the voltage level for data exchange between the controller and the laser PC is 24 volts.
  • the laser cell itself can have doors to the laser, which are equipped with door switches, to ensure the necessary security.
  • the door switches are used to switch off the laser when a door is opened.
  • the door switches can be connected to the laser safety circuit via an X25 interface connector.
  • the speed of the strip or of the tape 10 should be communicated to the laser.
  • an encoder signal from a motor of the drive system is communicated to the laser via special electronics in the form of a plug-in card for the laser PC.
  • FIG. 3 shows a block diagram with essential units of an embodiment of the device according to the invention. Shown are an encoder 20 of a motor of the drive device, a laser unit 22, the controller 24 (referred to as controller unit / interface card in FIG. 3) and a unit 26 for door contacts and a lamp of the laser cell.
  • the block diagram shown clarifies that the speed of the laser unit 22 is transferred from the encoder of the motor 20 via the signals A and B. As a result, the laser unit 22 can adapt its labeling accordingly to the speed of the belt 10 with parts 12.
  • the controller 24 functions as a central control unit for the laser unit 22.
  • the safety circuit of the laser cell is essentially formed by the unit 26, specifically by the door contacts contained in this unit. As soon as a door of the laser cell is opened, one of the door contacts is switched. The corresponding door contact.ZU signal is deactivated, which causes the laser of the laser unit 22 to be switched off.
  • the unit 26 comprises a lamp, which can be mounted on the laser cell, for example. This lamp shows the operation of the laser.
  • a typical function sequence comprises the following steps: After switching on the laser cell with the laser PC and the controller, the laser PC boots and the labeling software starts.
  • the software reads current data from a label code list in a text file.
  • the first position of the text file can then be transmitted to a so-called scan lab card in the laser unit 22.
  • the software now enables the meter readings to be reconfigured.
  • the software provides a form on a graphical user interface, such as the Windows operating system from Microsoft, in which various entries can be made in order to monitor and control the meter readings.
  • This form has a TRANSFER button with which the entered data can be transferred from the laser PC to the controller via a serial interface.
  • the controller can send the received data back to the laser PC.
  • the laser PC can then compare the sent and received data and display a message "Transfer successful" or "Transfer failed" on the graphical user interface.
  • the new settings are applied immediately and the labeling can be started after closing this input form.
  • the labeling can now be started with a high impulse with a duration of approx. 10 ms at the Restart_Mark signal, provided that the signals System_Ready, Laser_Ready, _Geladen and sequence program_active are all logically high.
  • a part is labeled with the same code. Between two successive trigger pulses it is checked whether the laser has set the signal Mark_Aktiv to logic high and then to logic low again.
  • the controller 24 When changing the bobbin, ie when a new bobbin is to be used and / or when a new data record is to be used for labeling, the controller 24 outputs the signal New_Data record.
  • the laser PC sets the Data_Loaded signal to logic low, ie to inactive.
  • the belt 10 with the parts 12 is stopped.
  • the laser PC loads the next data record from the mentioned text file onto the scan card.
  • the laser PC reports data_loaded as soon as the scan card has loaded the new data and is ready. Now the controller resets the signal new_data record and the tape is started.
  • the next trigger signal from the light barrier triggers on the signal Restart_Mark a label with the new code.
  • the laser is always active as long as the laser PC is switched on and there is no fault condition. This means that parts 12 can be labeled at any time.
  • the laser can be operated without a standby function, but this has no negative effects on the life of the laser. In standby mode, on the other hand, the heating time of the laser would be approx. 40 s.
  • the text file with a list of labeling codes for the parts can have the following structure: coil count code comment 1 xyz1 2 XYZ2 3 Xyz3
  • Fig. 4 now shows the process flow when labeling parts with a laser.
