- the clamping does not necessarily have to result in the section of the SMD tape 4.1, 4.2 coming to a standstill and being clamped; rather, the clamping can only occur so moderately that the friction is increased to a certain extent, so that the SMD -Band 4.1, 4.2 can only be pulled out of the grommet 31 with increased force, but can still be pulled out in principle.
- the pivotable braking device 32 can have a tab 33 which can form a lever.
- the braking device 32 can be opened or closed by the robot arm 6, when it guides the SMD component roll cassette 10.1, 10.2 using its gripper 13, in a suitable manner with the tab 33 against an obstacle or a shoulder, for example a Paragraph on the belt connector 7, whereby a force from the outside can act on the lever-like tab 33 in order to swing the braking device 32 open or closed.
- a data carrier can be attached to the housing 25 of the SMD component roll cassette 10.1, 10.2, which, in addition to its function as a data carrier, also forms a marking 24, by means of which the robot arm 6 can position itself with respect to the SMD component roll cassette 10.1, which is to be gripped. 10.2 can automatically align in order to be able to approach and grip the SMD component roll cassette 10.1, 10.2 detected via the marking using its gripper 13 guided by the robot arm 6.
- the first SMD component roll 3.1 can be rotatably mounted in a first SMD component roll cassette 10.1, as shown in FIGS. 7 to 11, which has at least one first driven wheel 11.1, which can be driven by a drive pinion 12 (FIG. 9) of a gripper 13 (Fig. 12 and Fig. 13) guided by the robot arm 6, with the first SMD component roll cassette 10.1 being driven by rotating the first driven wheel 11.1 the first SMD component roll 3.1 is rotated for winding or unwinding the first SMD tape 4.1 within the first SMD component roll cassette 10.1 in order to move the first SMD tape 4.1 synchronously with the automatic movement of the first SMD component roll cassette 10.1 on their path of movement between the changing magazine 2 of the SMD placement machine 1 and the belt connector 7.
- the second SMD component roll 3.2 can be rotatably mounted in a second SMD component roll cassette 110.2, which has at least one second driven wheel 11.2, which is driven by the drive pinion 12 of the gripper 13 guided by the robot arm 6 (FIGS. 12 and Fig. 13) can be driven, with the second SMD component roll 3.2 for winding or unwinding the second SMD tape 4.2 within the second SMD component roll cassette by driven rotation of the second output wheel 11.2 of the second SMD component roll cassette 10.2 10.2 is rotated in order to transport the second SMD tape 4.2 synchronously with the automatic movement of the second SMD component roll cassette 10.2 on its movement path between the belt connector 7 and the changing magazine 2 of the SMD placement machine 1.
- the automatic threading of the end section of the first SMD tape 4.1 into the automatic belt connector 7 is carried out by means of the robot arm 6 controlled by the robot controller 5 in a force/torque-controlled movement control manner Robot arm 6 carried out.
- the automatic insertion of the initial section of the second SMD tape 4.2 into the automatic belt connector 7 by means of the robot arm 6 controlled by the robot controller 5 is also carried out in a force/torque-controlled movement control manner of the robot arm 6.
- the robot arm 6, controlled by the robot controller 5, handles a standardized SMD component roll cassette 10.1, 10.2 of identical design and size, the standardized SMD component roll cassette 10.1, 10.2 being designed and set up, optionally an SMD component roll 3.1, 3.2 to store a specific size, a specific roll width, a specific roll diameter and/or a specific component type or to store an SMD component roll 3.1, 3.2 of a different size, a different roll width, a different roll diameter and/or a different component type.
- the standardized SMD component roll cassette 10.1, 10.2 can have a data carrier which, in addition to its function as a data carrier, also forms a marking with which the robot arm 6 can automatically align itself with respect to the SMD component roll cassette 10.1, 10.2 to be gripped. in order to be able to approach and grip the SMD component roll cassette 10.1, 10.2 detected via the marking using its gripper 13 guided by the robot arm 6.
- the robot arm 6 is arranged on an autonomous vehicle 14 and the autonomous vehicle 14 is designed to place the robot arm 6 between one Provision location at which SMD component rolls 10.1, 10.2 equipped with SMD components are provided for transport to an SMD assembly machine 1 in SMD component roll cassettes 10.1, 10.2, and the change magazine 2 of the SMD assembly machine 1, in which at least a provided SMD component roll cassette 10.1, 10.2 is to be loaded automatically.
