Description
Technical Field
The invention relates to a changing station for a pick-and-place machine for placing components on substrates, wherein the changing station comprises a component magazine receiving area for receiving at least one component magazine for supplying components to the pick-and-place machine. The invention also relates to an automatic assembling machine, a force-measuring cell, a method for measuring the assembly force of an assembly head of an automatic assembling machine, a computer program product and a non-volatile storage medium for storing a computer program product.
Background
In known pick-and-place machines, in particular in the form of pick-and-place machines, the force measurement is generally carried out by means of a printed circuit board force-measuring cell which comprises all the hardware required in the force measurement process, such as a force sensor, an oscilloscope, a card reader and a battery. Such a printed circuit board force-measuring cell is conveyed to a desired position by a conveyor unit of the pick-and-place machine. Once the printed circuit board load cell reaches the desired position, the assembly of the printed circuit board load cell to the force sensor is simulated. In other words, the segments of the respective assembly head are moved with a defined force downwards in the direction of the load cell until the displacer on the segment in the assembly head touches the previously learned Z position on the sensor surface of the load cell.
This process is performed without any components on the remover tip, repeated up to 100 times per segment to obtain statistically significant results. The measurement values of the load cells were evaluated by an oscilloscope integrated in a printed circuit board load cell. The measured force was associated with each segment, saved in an Excel file on a memory card in the printed circuit board force cell, and evaluated. The force measurement is both an integral part of the delivery and service area and is used to check the assembly force on site. In particular in the field, the components to be assembled become increasingly sensitive and have to conform with greater precision to the forces exerted in certain process steps, so that the customers nowadays increasingly pay more attention to the regular checking of the assembly forces. In some cases, it is also desirable to check the assembly force during the assembly process or at least during the respective reference run.
Conventional printed circuit board force cells have a relatively high height and therefore, for example, do not allow the use of a mounting head with a built-in vacuum tool. The removal and reinstallation of the vacuum tool means that the original assembly accuracy can be reached again by complicated and time-consuming modifications and adjustments. Such a method is impractical if the assembly force is to be checked periodically at short time intervals. In addition, during force measurement, the position of the currently used printed circuit board force cell wanders, resulting in measurement results that are misaligned. Heretofore, known printed circuit board load cells have not been able to remain in an automatic assembly machine for cyclic force measurement.
Disclosure of Invention
It is an object of the present invention to at least partly overcome the above problems. In particular, the object of the present invention is to propose an improved system for measuring the assembly force of an assembly head in an automatic assembly machine.
The solution of the invention to achieve the above object is found in the claims. In particular, the solution of the invention to achieve the object is a change table according to claim 1, a pick-and-place machine according to claim 6, a force-measuring cell according to claim 8, a method according to claim 10, a computer program product according to claim 12 and a non-volatile storage medium according to claim 13. Further advantages of the invention are found in the dependent claims, the description and the drawings. In the present invention, the features and details described in connection with the changing station are of course also applicable in connection with the pick-and-place machine according to the invention, the force-measuring cell according to the invention, the method according to the invention, the computer program product according to the invention and the storage medium according to the invention and vice versa, so that all aspects of the invention are or can be referred to each other always or in each case with regard to the disclosure.
According to a first aspect of the invention, a change station for a pick-and-place machine for mounting components to substrates is provided. The exchange station comprises a component cassette receiving area for receiving at least one component cassette for supplying components to the pick-and-place machine. The exchange station further comprises a force-measuring cell for measuring the assembly force of the assembly head of the automatic assembly machine, wherein the force-measuring cell is integrated into the component cassette receiving area.
Within the scope of the invention, the force measurement does not require the use of the current routine procedure, and it has been found that a stationary positioning of the force measuring cell on the exchange table provides a further advantageous multi-level improvement of the currently known force measuring systems. The force-measuring cell is integrated in a stationary manner in the exchange station, so that it is no longer necessary to transport the printed circuit board by means of the pick-and-place machine to drive the force-measuring cell. This is possible in particular because the mounting head of the universal automatic mounting machine can be moved through the actual mounting region into the component magazine receiving region of the exchange station and moved there in the direction of the force-measuring cell. In the exchange station according to the invention, a dummy assembly may be performed to determine the force in the component magazine receiving area or in the pick-up area of the conveyor otherwise positioned there. The integration of the force-measuring cell in the exchange station is also advantageous in that it is not necessary to remove any existing vacuum tools. The force-measuring cell which is installed outside the assembly region in the component magazine receiving region can also remain in the automatic assembly machine or in the exchange station during the assembly process and can be used for periodic force measurements, for example during a reference run or before the assembly of a new substrate and/or panel. This allows a decisive time advantage and thus also a cost advantage to be achieved.
A replacement station is to be understood to mean, in particular, a modular unit of an automatic placement machine, which is positioned and/or positionable in the vicinity of a placement area of the placement unit and has a component magazine receiving area for receiving at least one component magazine. A replacement station is understood to be a mounting unit for the integrated mounting of a force-measuring cell at a distance from the assembly space of the automatic assembly machine.
The force-measuring cell may comprise a housing which is designed, or at least substantially designed, in the form of a transmitter housing. In this way, the force cell can be easily positioned on the shuttle platform at the receptacle provided for the conveyor. No special housing for the force-measuring cell has to be produced. The solution according to the invention can thus be implemented in a correspondingly low-cost manner.
In principle, the force-measuring cell according to the invention can save more space than the currently customary printed circuit board force-measuring cells, so that the force-measuring cell can also be integrated into a component-cartridge replacement remover. Such a component magazine can remain in the change drawer during the periodic force measurement, requiring very few different types of drawers per storage space, or a quick change of magazine as required without any tools. The advantage of this solution is that the required force measurement can be carried out on the placement site without a typical exchange table, for example in the case of a built-in wafer system, or in the case of a change table in which there is not sufficient space for a separate force measuring cell.
The substrate is understood to mean, in particular, a printed circuit board. The load cell preferably has at least one load cell. The load cell may include a housing having a load cell mounted to an outer region of the housing. An element is understood to be a part (i.e. a single functional part) or an element having a plurality of functional parts assembled into a functional unit. The integration of the force-measuring cell into the cell receptacle region can be understood as: the force-measuring cell is mounted in and/or on the exchange table in a form-fitting and/or force-fitting manner, in particular not only on the exchange table.
According to a further embodiment of the invention, a holding section for holding the force-measuring cell in the element cassette receiving area can be provided in the exchange table in the element cassette receiving area, and the force-measuring cell has a counter-holding section complementary thereto, in order to establish a form-fitting and/or force-fitting connection between the holding section and the counter-holding section. By means of the holding section, a stable positioning of the force-measuring cell on the exchange table can be achieved. During the force measurement, unintentional movements of the force-measuring cell can be prevented, so that particularly precise force measurements can be carried out with the changing table according to the invention. As mentioned above, the force-measuring cell can comprise a housing which is designed in the form of a universal-type transmitter, or at least has a corresponding outer contour or substantially has such an outer contour. The housing may in particular have the shape of a conveyor and/or the force-measuring cell may be integrated into the housing of the conveyor. This allows a low-cost and simple integration of the force-measuring cell in a form-fitting and/or force-fitting manner into existing pick-and-place machines (for example pick-and-place machines of the "SIPLACE" type), the mounting head of which can approach the exchange station.
Furthermore, in the exchange station according to the invention, the force-measuring cell can have an inductive receiver, while the base body of the exchange station has an inductive transmitter, in order to provide an inductive voltage for the force-measuring cell via the inductive receiver. This eliminates visible, in particular protruding, power supply connections. The outer surface of the housing of the force-measuring cell can thus be of a relatively smooth and/or flat design. This in turn facilitates simple and/or rapid mounting and dismounting of the force-measuring cell. The exchange station or the pick-and-place machine with the exchange station may comprise a Control Unit, in particular a so-called Feeder Control Unit (Feeder-Control Unit), which is configured to supply the inductive receiver with voltage. A base body of the exchange table is to be understood to mean, in particular, a table-like base body of the exchange table, in which a force-measuring cell is integrated and/or can be integrated.
Furthermore, in the exchange table according to the invention, the force-measuring cell can have at least one connecting contour, wherein the connecting contour is arranged and/or can be arranged so as to be able to move without damage in at least one corresponding connecting guide of the exchange table. This makes it possible to mount the force-measuring cell in and/or on the exchange table in a simple, rapid and yet stable manner. The force-measuring cell preferably comprises a housing with said connecting contour. A load cell for measuring the mounting force of the mounting head of the automatic mounting machine can be provided in the outer region of the housing. The cross section of the housing of the force-measuring cell can have an omega-shaped profile or a substantially omega-shaped profile. In this case, the two connecting profiles can form the "spur" of the omega-shaped profile, viewed from one end of the cross-section. Such a housing profile can be mounted in and/or on a changing table quickly, simply, stably and space-effectively. The connecting contour is understood to be in the form of an edge-like projection from the housing of the force-measuring cell. In addition to the projection or the at least one connecting contour, a recess and/or a groove can also be provided, whereby the projection or the at least one connecting contour is formed. The at least one connection guide may be designed in the shape of a corresponding groove and/or groove accommodating the connection profile. In a preferred embodiment of the exchange table, the force-measuring cell has two connecting contours, wherein the two connecting contours are arranged and/or can be arranged so as to be movable in two corresponding connecting guides of the exchange table without being damaged.
According to a further embodiment of the invention, the force-measuring cell can have at least one latching means for establishing a latching connection with a counter-latching means of the exchange table. In particular in combination with the above-described connection system, it is possible to create a system for quick, simple and stable mounting of a force-measuring cell in and/or on a change table. The latching mechanism may have a latching recess (latching recess) or a latching projection. The counter locking mechanism can also have a locking recess or a locking projection. Preferably, the latching mechanism has a latching recess, and the counter-latching mechanism has a latching projection for engaging into the latching recess. The force-measuring cell or the housing of the force-measuring cell can be held in the desired position in and/or on the exchange table, for example in the x-direction by means of the above-described connection system and in the y-direction by means of the latching system. The possible positional deviations of the load cells in the load cell are thus smaller and the measurement accuracy correspondingly higher compared to currently known load cells.
According to another aspect of the present invention, there is provided an automatic assembling machine comprising a change station as described above. At the same time, the advantages of the pick-and-place machine according to the invention are the same as those already described in detail with respect to the change station according to the invention. The pick-and-place machine is therefore understood to be a pick-and-place machine system comprising at least one exchange station.
The pick-and-place machine according to the invention may comprise a mounting head and a control unit for controlling and/or regulating the movement of the mounting head, and a signal connection unit for establishing a signal connection between the load cell and the control unit for transmitting measurement data and/or component data from the load cell to the control unit. By means of the signal connection unit, the measured values from the force measuring process on the force measuring cell by means of the mounting head can be transmitted directly from the force measuring cell to any measured value evaluation unit, for example into a control unit. The storage medium, which is customary at present and is inserted into the force-measuring cell, for example in the form of a memory card, can be dispensed with. In particular, the manual transmission of data to the measured value evaluation unit can be dispensed with, wherein the memory card is manually removed from the memory location in the force-measuring cell and the applicable reading unit is inserted again in the new memory location. This simplifies the operation of obtaining the desired force measurement data. In addition, customers who do not allow the use of storage media in production may prefer such a pick-and-place machine. The Control Unit is understood to be a so-called Feeder Control Unit (Feeder-Control Unit). By means of the signal connection unit, the force-measuring cell can also be moved into and/or onto the exchange table without a predetermined position being required, but this position can be automatically recognized by the existing sensor system. The signal connection may be established by wire or wirelessly. The signal connection unit can accordingly have a signal connection line for the wired establishment of a signal connection, a radio transmitter and/or a radio receiver for the wireless establishment of a signal connection, in particular for the wireless transmission of measurement data and/or element data from the force-measuring cell 13 to the control unit 26. The force-measuring cell can thus in principle be mounted anywhere in and/or on the exchange table. Subsequently, only the force measurement needs to be selected. After the measurement, automatic location identification and evaluation of the data may be performed. It is even possible to carry out the measurement of forces during the machine reference operation and/or at predefinable time intervals or events, for example when inserting new panels and/or assembling sensitive substrates and/or components. The measurement data can be understood as data obtained during the measurement of the force. The component data can be understood as component-specific data and/or values of the force-measuring cell, such as the size, orientation and/or position of the force-measuring cell in and/or on the exchange table.
A further aspect of the invention relates to a force-measuring cell for measuring a mounting force of a mounting head of an automatic mounting machine, wherein the force-measuring cell is configured to be integrated into a change station according to the preamble. At the same time, the force-measuring cell according to the invention likewise has the advantages described above. Such a force-measuring cell has a counter-holding section complementary to the holding section for establishing a form-fitting and/or force-fitting connection between the holding section and the counter-holding section. The force-measuring cell may further comprise an inductive receiver for an inductive voltage supply of the force-measuring cell. In addition, the force-measuring cell can have at least one connecting contour, wherein the at least one connecting contour can be arranged and/or positioned such that it can be moved without damage in at least one corresponding connecting guide of the exchange table. Furthermore, the force-measuring cell can have at least one latching means for establishing a latching connection with a counter-latching means of the exchange table. The force-measuring cell may further have a housing in the form of a universal transmitter or substantially in the form of a universal transmitter.
A further aspect of the invention relates to a method for measuring the assembly force of an assembly head in a pick-and-place machine as described above. The method comprises the following steps:
-measuring the assembly force; and
-transmitting the measurement data and/or the element data from the force-measuring cell to the control unit.
At the same time, the method according to the invention also has the advantages described above. The measurement data and/or the component data are preferably transmitted by means of a signal connection unit. In the method according to the present invention, the following steps may be further included:
-determining or judging the components to be supplied to the pick-and-place machine for the placement process; and
-performing a force measurement by means of the force-measuring cell of the change table, after which the assembly process is performed when the identified component corresponds to a predefined component.
By means of the force-measuring cell and the signal connection unit integrated in the exchange station, force measurements can be carried out at any point in time. For example, particularly sensitive substrates and/or components may be subjected to force measurements prior to the assembly process to ensure that the assembly force of the assembly head is within a specified target range.
The invention further relates to a computer program product comprising instructions which, when the computer program product is executed by a computer, cause the computer to carry out the method as described above. Such a computer program product may be installed in the control unit and/or in a computer or a corresponding processing unit in signal connection with the control unit. Furthermore, the invention relates to a non-volatile storage medium having such a computer program product stored thereon.
The computer program product may be implemented as computer readable instruction code in any suitable programming language, such as Java, C + +, C #, and/or Python. The computer program product may be stored on a computer readable storage medium such as a data disk, a removable drive, a volatile or non-volatile memory, or an internal memory/processor. The instruction code may program a computer or other programmable device, such as a control unit, in such a way as to perform the required functions. Furthermore, the computer program product may be provided in a network, such as the internet, or the computer program product may be downloaded therefrom, if desired by a user. The computer program product may be realized by means of a computer program, i.e. software, or by means of one or more special-purpose electronic circuits, i.e. in hardware, or in any hybrid form, i.e. by means of software components and hardware components.

Detailed Description
Fig. 1 shows a change station 10a of a pick-and-place machine 100 (schematically shown in fig. 5) for placing components on substrates. The illustrated replacement station 10a includes a component cartridge accommodating area 11 for accommodating a component cartridge (such as a conveyor) for supplying a component to the automatic mounter 100, and a force measuring unit 13 for measuring a mounting force of a mounting head 14 (shown in fig. 5) of the automatic mounter 100. The cell receptacle 11 has a holding section 15 for holding the load cell 13 in the cell receptacle 11. The force-measuring cell 13 has a counter-holding section 17 (not shown in detail) complementary to the holding section 15 for establishing a form-fitting and force-fitting connection between the holding section 15 and the counter-holding section 17. The force-measuring cell 13 can be integrated into the cell receptacle 11 in a corresponding form-fitting and force-fitting manner. In the present exemplary embodiment, the force-measuring cell 13 essentially has a housing 16 of a universal-type conveyor.
The exchange station 10a shown in fig. 1 has a base body 12. The force-measuring cell 13 shown has an inductive receiver 18, while the base body 12 has an inductive transmitter 19 for supplying an inductive voltage to the force-measuring cell 13 by means of the inductive receiver 18.
Fig. 2 shows a replacement station 10b according to a second embodiment. According to a second embodiment, the cross section of the force-measuring cell 13 has an omega-shaped profile, so that there are two connecting profiles 21. The connecting contour 21 can be moved without damage in two corresponding slotted connecting guides 22 of the exchange table 10 or the base body 12.
The base body 12 and the force-measuring cell 13 are shown in detail in fig. 3 and 4. In particular, a latching mechanism 23 of the force-measuring cell 13 can be recognized in the figure for establishing a latching connection with a mating latching mechanism 24 of the exchange table 10. The latching mechanism 23 is configured in the form of a latching chamber. The mating latch mechanism 24 is configured in a snap-fit fashion. The force-measuring cell 13 can be prevented from moving in the x-direction on the exchange table 10b or on the base body 12 by the connection system 21, 22. The force-measuring cell 13 can be prevented from moving in the y direction on the exchange table 10b or on the base body 12 by the latching systems 23, 24. Fig. 4 also shows a mounting head 14 which can be moved onto the load cell 20 of the load cell 13 to carry out the desired load measurement.
Fig. 5 schematically shows a block diagram illustrating a pick-and-place machine 100 having a changing station 10b according to the second exemplary embodiment described above. The pick-and-place machine 100 comprises a mounting unit 29 with a mounting head 14 and a control unit 26 for controlling and/or regulating the movement of the mounting head 14. The pick-and-place machine 100 further comprises a signal connection unit 25 for establishing a signal connection between the load cell 13 and the control unit 26 for transmitting measurement data and/or component data from the load cell 13 to the control unit 26. The Control Unit 26 is designed in the form of a so-called Feeder-Control Unit and has a non-volatile storage medium 28 on which a computer program product 27 is stored or installed. The computer program product 27 comprises instructions which, when the computer program product 27 is executed by a computer, for example in the control unit 26, cause the computer to carry out the method as described below with reference to fig. 6.
Fig. 6 is a flowchart for explaining a method for measuring the mounting force of the mounting head 14 in the above-described automatic mounting machine 100. In a first step S1, first, the assembly force is measured by means of the force-measuring cell 13. In a subsequent step S2, the measurement data and/or the element data thus obtained are transmitted directly from the force-measuring cell 13 to the control unit 26 via the signal connection unit 25.
The invention allows more design principles than the illustrated embodiments. In other words, the invention should not be regarded as being limited to the embodiments set forth in connection with the drawings. The location of the load cell 20 should not be considered limited to the illustrated location. The method can also be further configured such that components to be supplied to the automatic placement machine 100 for the placement process are identified and the components are measured by means of the measuring cell 13 of the change station 10, after which the placement process is carried out with the identified components when they correspond to predefined components. In other words, once it is identified that, for example, the assembly process is to be carried out with particularly sensitive elements, the measurement of the forces is carried out before assembly.
