Definitions
- the invention relates to a method for automatically reloading SMD component rolls on SMD assembly machines.
- the CN 212711952 U relates to the technical field of SMT material receiving devices, in particular to an SMT material receiving machine, which comprises a suction device for sucking a material receiving belt, a pressure roller and a drive device, the drive device being connected to the suction device and the pressure roller and the Drive device drives the suction device to suck in the material receiving belt and to convey the material receiving belt to the position above the SMT material belt in order to be attached to the SMT material belt.
- the driving device drives the pressure roller to roll the surfaces of the material receiving tape and the SMT material tape that are attached to each other, so that the material receiving tape and the SMT material tape are fully adhered to each other and the success rate of covering the shroud is improved. With such a device, two SMD tapes of two SMD component rolls can be automatically connected.
- the object of the invention is to create a method with which SMD component rolls on SMD assembly machines are fully automatic, i.e. H . in particular without any intermediate work steps to be carried out by a human.
- the task is solved by an automatic procedure
- Reloading SMD component rolls on SMD assembly machines comprising the steps:
- SMD assembly machines are machines for automatically assembling electronic circuit boards with electronic components.
- the components are generally automatically placed or glued onto the circuit board and then automatically connected to electrical conductor tracks of the circuit board in a soldering bath, for example, to produce the electrical contacts.
- An exemplary SMD assembly machine includes a magazine station with unpopulated circuit boards, a conveyor device for feeding the circuit boards in a serial sequence, the actual assembly machine in which the required SMD components are picked up one after the other and placed on the respective circuit board at the designated locations , as well as an oven in which the SMD components placed on the circuit board are soldered. Finally, the completed, i.e. H . The assembled circuit boards are stacked into a delivery magazine. This manufacturing process is largely automated.
- the large number of SMD components to be assembled are provided as SMD tapes, each sorted on an SMD component roll.
- a separate SMD component roll is required for each individual SMD component.
- Each SMD component roll contains an SMD tape, which includes a carrier tape on which a large number of SMD components of identical design are attached at regular intervals.
- each type of SMD component can be continuously fed to the SMD assembly machine, so that the SMD assembly machine can continuously and preferably without interruption equip the circuit boards with the required SMD components.
- an SMD component roll is almost used up, i.e. H .
- the used SMD component roll must be removed and replaced with a fully populated new SMD component roll. So that the SMD assembly machine can continue to produce uninterruptedly, the SMD tape of the new SMD component roll must be seamlessly attached to the end of the previous SMD tape of the idle SMD component roll. The attachment should be done in such a way that on the assembled carrier tape the distance of the first SMD component of the new SMD component roll from the last SMD component of the idle SMD component roll is as close as possible to the standardized distance of the several SMD components in each case from each other on an SMD component roll.
- the invention therefore specifically deals with the fully automated reloading of new SMD component rolls as successor rolls for idle SMD component rolls, whereby an automatically operating belt connector is also automatically connected to the end of the idle SMD component roll by the robot proposed according to the invention and the beginning of the new SMD component roll is loaded so that the end and beginning can be automatically connected in the automatically operating belt connector.
- the SMD component roll includes a tape drum and an SMD tape wound on it.
- the SMD tape comprises a carrier tape, in particular with perforations at the edge at equal intervals, for precise positioning of the carrier tape, and a large number of SMD components, which are applied to the carrier tape at even distances from one another in a serial chain.
- the SMD component roll can be housed in a cassette described in more detail below.
- the SMD component rolls described below can therefore always be SMD component rolls which include a cassette in which the tape drum is stored together with the SMD tape wound on it.
- a first SMD component roll is first automatically removed, which carries a first SMD tape, which continues to be inserted into the SMD strip during ongoing operation of an SMD assembly machine.
- the assembly machine expires.
- the first SMD component roll is initially located in a change magazine of the SMD assembly machine.
- the SMD placement machine works continuously automatically, even while the method according to the invention is being carried out, i.e. H . uninterrupted, so that while the first SMD component roll is automatically removed from the change magazine, the first SMD tape continues to be drawn into the SMD placement machine in order to place the SMD components located on the first SMD tape one after the other within the SMD -Assembly machines can be removed and printed circuit boards can be automatically assembled with them.
- the SMD assembly machine has a feeder that automatically feeds the first SMD tape into the SMD assembly machine. This specifies a maximum tensile force that may act on the first SMD tape.
- a minimum tensile force should also be maintained so that it is ensured that the first SMD tape is under a certain tensile stress, so that there is no risk of loops forming or a swelling, jerky running of the first SMD tape from the first SMD component. role is prevented.
- the robot control can therefore be designed and set up to move the robot arm in such a way that during the automatic transport of the first SMD component roll from the change magazine to the belt connector, the first SMD tape still running out of the first SMD component roll is below the permissible, i.e. H . desired tension is present.
- the movement path that the robot arm specifies for the first SMD component roll can therefore be coordinated with this.
- a removable magazine usually has several slots, each of which has an SMD component roll of a specific SMD component type inserted.
- the slots are designed like slots, so that several SMD component rollers are arranged next to one another, with their main extension planes each parallel to one another and with their roller axes of rotation each parallel to one another.
- the robot control can therefore be designed and set up to control the robot arm in such a way that the robot arm handles the gripped SMD component roll by means of its gripper, which is moved by the robot arm, in such a way that the SMD component roll is in is pulled out of the change magazine in a direction parallel to its main extension plane, d. H . is pulled out in a direction perpendicular to the roller axis of rotation.
- an end section of the first SMD tape is then automatically threaded into an automatic belt connector by means of the robot arm controlled by the robot controller.
- the belt connector usually has a feed slot which is intended to briefly accommodate the first SMD component roll and/or, later, the second SMD component roll, so that the respective end section of the first SMD tape first SMD component roll or the initial section of the second SMD tape of the second SMD component roll can be automatically detected by the belt connector, for the subsequent automatic connection of the end section of the first SMD tape to the initial section of the second SMD tape.
- the first SMD component roll is automatically separated from the first SMD tape within the belt connector.
- the separated first SMD component roll is placed in a clipboard magazine by an automatic second movement of the robot arm, controlled by the robot controller. This makes the gripper guided by the robot arm fer free to pick up and handle the second SMD component role, i.e. H . to be able to move automatically.
- the second SMD component roll which carries a second SMD tape, is then picked up from a pick-up magazine by means of the robot arm controlled by the robot controller.
- the second SMD component roll will generally be a new SMD component roll, i.e. H . be an SMD component roll that is completely populated with SMD components.
- the SMD component roll is in particular completely filled with the populated SMD tape.
- the receiving magazine can therefore form a storage location in which completely filled SMD component rolls are stored.
- an initial section of the second SMD tape is then automatically threaded into the automatic belt connector by means of the robot arm controlled by the robot controller.
- the belt connector has the feed slot already mentioned, which is intended to briefly accommodate the second SMD component roll, so that the respective initial section of the second SMD tape of the second SMD component roll is automatically captured by the belt connector for the subsequent automatic connection of the end section of the first SMD tape to the start section of the second SMD tape.
- the second SMD component roll is automatically inserted into the changing magazine of the SMD placement machine after the initial section of the second SMD tape of the second SMD component roll in the belt connector is automatically connected to the end section of the first SMD tape connected is . Since the beginning section of the second SMD tape of the second SMD component roll is already connected to the end section of the first SMD tape at this point in time, during the automatic insertion of the second SMD component roll into the changing magazine of the SMD placement machine a tensile force is exerted on the second SMD tape. As when removing the first SMD component roll from the change magazine, when inserting the second SMD component roll into the change magazine, the robot arm controlled by the robot control is controlled in a force/torque-controlled movement control manner.
- the robot control can therefore be designed and set up to control the robot arm in such a way that the robot arm handles the gripped second SMD component roll by means of its gripper, which is moved by the robot arm, in such a way that the second SMD component roll Roller is inserted into the change magazine in a direction parallel to its main extension plane, i.e. H . is inserted into the change magazine in a direction perpendicular to the roller axis of rotation.
