Definitions
- the invention relates to a device for gripping and transporting substrates, in particular wafers, printed circuit boards, solar cells or the like, with a gripping head having at least one support surface for placement on a substrate and at least one suction device for sucking the substrate against the support surface, wherein the suction device has a plurality of negative pressure acted upon vacuum chambers, the associated with the support surface suction openings fluidly connected / connectable and are separated from each other in the longitudinal direction of the gripping head.
- devices have emerged that no longer grip the substrate in a form-fitting or mechanical manner, but hold it by a negative pressure or a vacuum, or grasp and transport it.
- devices which have a gripping head, which have at least one support surface for placement on the respective substrate.
- the gripping head is thus not brought from below to the substrate or from the side, but rather from above onto the substrate, or the substrate is brought from below to the gripping head.
- a gripping head to a suction device which generates the vacuum or the negative pressure to suck the substrate against the support surface so that it is held or gripped by the negative pressure.
- the invention is therefore an object of the invention to provide a device for gripping and transporting substrates, which is inexpensive and technically easy to manufacture.
- the object is achieved by a device having the features of claim 1.
- This has the advantage that the gripping head or at least the vacuum chambers of the gripping head are created by a simple technical precaution, whereby differently sized gripping heads and a different number and size of vacuum chambers can be produced in a simple manner, so that an adaptation of the device or the gripping head with regard to certain boundary conditions and / or requirements can be realized without much extra effort. Because it can be used on known manufacturing processes, the production is also cost.
- provision is made for the vacuum chambers to be formed by at least one hollow profile, which has a hollow chamber in which at least one separate separating element for producing adjacent vacuum chambers is arranged.
- a hollow profile is characterized in that, seen in the longitudinal direction, it has a non-changing cross section as in the case of an extruded profile.
- a hollow chamber extending continuously or extending along the longitudinal extent of the hollow profile can be created in a simple manner, by means of which the introduction of separating elements can be subdivided into separate vacuum chambers in a simple manner.
- two separating elements In order to produce the desired size of a vacuum chamber, two separating elements must be arranged only in the appropriate distance from each other in the hollow chamber. Characterized in that separate separating elements are used, the hollow chamber can be formed by the hollow profile and subsequently subdivided.
- the respective separating element is in particular in the hollow chamber and positioned and fixed at the desired location for forming the respective vacuum chamber.
- an outer contour of the separating element corresponds at least substantially to the cross section of the hollow chamber in order to separate adjacent vacuum chambers from one another in a dense manner.
- the outer contour of the separating element is made with excess in relation to the cross section of the hollow chamber, so that between the separating element and the hollow chamber a press fit occurs when the separating element is inserted into the hollow chamber.
- the hollow profile has at least one first transverse bore leading into the hollow chamber, in which a fastening screw for locking the separating element in the hollow chamber is inserted / inserted.
- the hollow profile has seen in its longitudinal extension several in particular evenly distributed transverse bores through which the fastening screw can be performed in order to fix the one or more separating elements seen at different positions in the longitudinal extension of the Hohlpro fils.
- the respective separating element has at least one circumferential and elastically deformable sealing lip, which in the inserted state is prestressed against the inside of the hollow chamber.
- a sealing compound is introduced through the first or a second transverse bore of the hollow section.
- the sealant ensures that any existing space between the separating element and the hollow chamber or inner wall of the hollow chamber is sealed.
- the fact that the sealant is introduced through the first transverse bore or second transverse bore it is ensured that sealant directly between the separator and the hollow chamber or their inner wall passes.
- the sealant is introduced through the first transverse bore before the fastening screw is inserted.
- the sealing compound is preferably introduced through the second transverse bore, while the separating element is already locked in the hollow chamber by a fastening screw inserted through the first transverse bore.
- the second transverse bore is expediently at the same height, seen in the longitudinal extent of the hollow profile, formed in the Hohlpro fil as the first transverse bore to ensure easy installation and sealing.
- one of the outer contour following lateral surface of the separating element has a groove which extends in the circumferential direction of the separating element and is aligned in the locked position by the fastening screw with the first and / or second transverse bore.
- This ensures that the introduced by the first or second transverse sealant seal is introduced into the groove of the separating element.
- the sealant distributed along the groove around the separator around. This ensures that the sealing compound can always completely surround the separating element along the groove, so that an advantageous sealing is fully guaranteed.
- the sealant is silicone, in particular permanently elastic silicone. As a result, a safe separation of the vacuum chambers is guaranteed from each other in the long term.
- an outlet opening for the sealing compound is formed in the hollow profile.
- the outlet opening may be formed, for example, by the second or a third transverse bore.
- the outlet opening allows the sealant to escape from the hollow profile again. This ensures in a simple manner that so much sealant is introduced until all air pockets were expelled.
- the sealing compound projecting from the outlet opening can serve as a sealing element outside the hollow chamber, in particular as a separating element in a longitudinal groove of a track for a transport belt, as will be discussed in more detail later.
- each Venturi nozzle is associated with a controllable valve which is assigned to a suction connection of the Venturi nozzle connected to the respective vacuum chamber in order to completely open or completely close the suction-side throughflow cross section as required.
- the valve is designed as a proportional valve, so that it can also assume intermediate states in order, for example, to only partially release the throughflow cross section.
- a transport device for moving a sucked substrate along the support surface is arranged on the gripper head.
- the sucked substrate can thus be moved along the support surface and displaced, for example, from the region of a first vacuum chamber into the region of a second vacuum chamber, which can be individually pressurized, in particular by means of the aforementioned valves and venturi nozzles, with a negative pressure. This ensures that a substrate can be sucked in on one side of the gripping head and a substrate can be deposited on the other side at the same time.
- the transport device has at least one transport belt, which extends in the longitudinal extent of the hollow profile and forms the bearing surface.
- the fact that the support surface is formed by the transport belt it is avoided that during transport of the substrate relative movements between the substrate and support surface arise, through which the substrate could be damaged. This reduces the wear and reduces the load on the substrates to be transported.
- the mammal openings are formed in the transport belt, wherein each vacuum chamber has through openings in the hollow profile, which lead from the vacuum chamber to a tread or track of the conveyor belt. This is ensured by fluidic connection between the vacuum chambers and the mammalian openings by means of the passage openings in the hollow profile.
- the suction openings and conveyor belts and the passage openings in the high profile are uniformly spaced from each other, so that the substrate permanently or independently of the position along the Support surface can be sucked by the gripping head and held.
- the suction openings are formed in the transport belt in a plurality of groups, each group having a plurality of suction openings, which are arranged uniformly distributed, wherein the groups themselves have a greater distance compared to each other.
- the passage openings open into a longitudinal groove in the running surface, which lies below the conveyor belt, wherein the suction openings are formed in the region of the longitudinal groove in the transport belt.
- the longitudinal groove in the longitudinal extent is preferably likewise divided by further separating elements, the separating elements preferably being formed by the sealing compound emerging from the outlet opening, as already described above become.
- these are in particular on the underside of the conveyor belt and separate the adjacent negative pressure areas along the tread or the longitudinal groove in the tread from each other.
- these further separating elements are designed as plug-in parts which are inserted into a passage opening or transverse bore.
- the transport device has at least two, in particular exactly two of the transport belts, which are arranged parallel to one another and at a distance from one another on the gripping head.
- the transport belts are formed as described above and held on the gripping head.
- both transport belts each have a plurality of mammalian openings which cooperate with passage openings in the support structure and associated vacuum chambers.
- the adjacent conveyor belt can cooperate with one or with a common vacuum chamber.

- the opposing vacuum chambers 10, 11, 12 are in each case connected to a suction channel 9 of the associated intermediate element 5.
- the vacuum chambers 10, 11, 12 are each connected to the suction side with one of the Venturi nozzles 6, so that upon pressurization of the Venturi nozzles 6 at the respective pressure port 7, a negative pressure to the respective vacuum chamber 10, 11, 12 is generated.
- the hollow sections also have a multiplicity of side-by-side through openings 14, which in the present case are formed as through-holes, and open on one side into the respective vacuum chamber 10, 11 or 12 and at the other end on a tread 15 for a conveyor belt 16 end.
- the transport belt 16 is part of a transport device 17 which comprises two transport belts 16, each of which rotates one of the Hohlpro file 4 in its longitudinal extent.
- two deflection rollers 18 and 19 are arranged at the longitudinal ends of the Hohlpro file 4 and at the end-side intermediate elements 5, which are rotatably supported on the support structure 3.
- the axes of rotation of the deflection rollers 18 and 19 are aligned parallel to one another and perpendicular to the longitudinal extent of the gripping head 2.
- the respective transport belt 16, which rotates around the gripping head 2 thus revolves it both on the underside and on its upper side.

- the groups 23 of the adjacent conveyor belts 16 are arranged side by side, as shown in FIG.
- the suction openings 22 may be evenly distributed, so not grouped, distributed along the conveyor belt 16.
- the mammal openings 22 are formed centrally in the respective transport belt 16 and therefore are in operative connection with the respective longitudinal slot 21 or the respective vacuum chamber 10, 11, 12, depending on the position in which the respective transport belt 16 is located. Due to the longitudinal slot 21 in the tread 15 ensures that over the entire length of the hollow profile continuously negative pressure on the mammalian openings 22 can rest, at least when all three Venturi nozzles 6 acted upon with compressed air and suction side with the respective vacuum chamber 10, 11, 12 are connected ,
- FIG. 3 shows, in an enlarged detailed sectional view, a detail from FIG. 1, which is identified by a circle A in FIG.
- the vacuum chambers 10, 11, 12 are formed in the respective Hohlpro fil 4 by a longitudinal extent of the hollow section 4 extending hollow chamber 25, wherein the hollow chamber 25 is subdivided by separating elements 24 into the individual vacuum chambers 10, 11, 12.
- This allows cost-effective production, because the hollow sections 4 can be produced, for example, as extruded profiles.
- the respective separating element 24 is subsequently inserted into the hollow chamber 25, so that the three vacuum chambers 10, 1 1, 12 arise, which are each associated with one of the venturi 6.
- the longitudinal groove 21 is also divided by dividing elements 26 into three sections corresponding to the vacuum chambers 10, 11, 12.
- These separating elements 26 are formed for example as projections which bridge the longitudinal groove 21, and on which the respective transport belt 16 rests, as shown by way of example in FIG.
- the separating elements 24 expediently have an outer contour which corresponds to the cross section of the hollow chamber 25 in order to separate the vacuum chambers 10, 11, 12 as well as possible from each other in terms of flow.
- the separating elements with their insertion into the hollow chamber 25 with a sealant, in particular silicone, which preferably hardens permanently elastic, encapsulated in order to ensure a secure seal.
- the separating elements each have a circumferential groove into which the sealing compound is introduced from the outside.
- the hollow sections 4 expediently transverse bores, through which the sealant can be introduced.
- so much sealant is introduced that the sealant protrudes from one of the transverse bores, this transverse bore then opening in particular into the longitudinal groove 21.
- the then protruding sealing compound forms the separating elements 26, by which the longitudinal groove 21 in the respective areas, the vacuum chambers 10, 11, 12 assigned, is divided.
- FIG. 4 shows a cross section through the gripping head 2.
- the cross section along the line C - C from FIG. 2 is shown, so that the cross section leads through the vacuum chamber 10.
- the conveyor belt 16 is securely guided on the respective Hohlpro fil 4, this particular has a guide 27 for the conveyor belt 16.
- the guide is designed in particular form-fitting and can be realized in different ways.
- the respective transport belt 16 on the inside a receptacle 28, in which the support structure 3, in particular the respective hollow profile 4 or a guide profile arranged thereon 29, which will be discussed in more detail later, with the tread 15 rests in regions, so that the transport belt 16 engages around the running surface 15 laterally.
- the side of the transport belt 16 is thereby guided in a simple manner by the support structure 3 in a form-fitting manner in the longitudinal direction.
- Each of the venturi nozzles 6 furthermore has a controllable valve 30, which is assigned to the suction connection 9 of the respective venturi nozzle 6.
- the switching valves 30 are in particular designed to completely release the flow cross-section of the suction connection or to completely close it.
- the valves 30 are designed as proportional valves, which also allow an intermediate position in which, for example, the flow cross-section will only partially release.
- the gripping head 2 is first guided downwards and placed on a substrate, for example a waver, or the substrate is guided from below to the gripping head 2. This is done, for example, such that the gripping head 2 is placed in the region of the vacuum chamber 10 on the substrate.
- a negative pressure in the vacuum chamber 10 is generated, which acts through the vacuum chamber 10, the through holes 14, the longitudinal groove 21 and the suction openings 22 on the substrate and this attracts against the conveyor belt 16.
- the drive device 20 is actuated to move the transport belts 16, so that the substrate is moved along the support surface 29 on the gripper head 2.
- the substrate is displaced, for example, from the region of the vacuum chamber 10 into the region of the vacuum chamber 11 or the vacuum chamber 12. Once there, the substrate can be quickly deposited by the respective valve 30 is driven to close the respective suction-side flow cross-section of the corresponding Venturi nozzle 6.
- FIG. 5 shows an advantageous development of the device 1 in a perspective detail view.
- This shows the pulleys 18 of the transport device 17, which are mounted on a common shaft.
- the shaft 30 is rotatably mounted in a housing part 31.
- the housing part 31 is displaceable relative to the support structure 3 of the gripping head 2 in its longitudinal extent.
- the housing part 31 is associated with a pneumatic actuator 32, which moves the housing 31 with the deflection rollers 18 against the clamping force of the transport belt 16 in order to set a desired belt tension.
- the actuator 32 to a pneumatic cylinder 33, in which a pneumatic piston 34 is arranged axially displaceable.
- the pneumatic piston 34 is connected to the housing part 31 in order to displace it against the tensioning force of the transport belts 16, as indicated by an arrow 35.
- the pneumatic actuator 32 can be acted upon, for example, by the same compressed air generator, as well as the venturi 6. Alternatively, the actuator 32 has its own compressed air generator. Because compressed air is used here as a means of generating force, it is ensured that the transport belt 16 is not overstretched.
- an optional Spring element 36 which is biased between the support structure 3 and the housing part 31, the housing part 31 is also urged against the clamping force of the conveyor belt 16 to the outside. This ensures that the transport belts 16 do not jump off the deflection rollers 18 in the event of a pressure failure of the pneumatic actuator 32. As a result, a safe and permanent operation of the device 1 is ensured.
- the actuator 32 thus forms together with the movably mounted deflection rollers 18, a belt tensioner 38, by means of which the tension of the transport belt 16 is adjustable. This ensures that the conveyor belts 16 do not detach from the running surface 15 of the hollow file 4, which would result in a false air and thus a release of the negative pressure, which could lead to a substrate being detached from the gripping head 2.
- the pneumatic belt tensioner 38 By means of the pneumatic belt tensioner 38, thermal changes and signs of aging of the transport belts 16 can be taken into account and compensated during operation.
- the belt tensioner 38 allows a simple and tool-free replacement of the conveyor belt.
- the support structure 3 and the Hohlpro file 4 are formed such that the tread 15 is formed curved downwards or in the direction of the substrate to be gripped.
- the curvature is formed such that it biases the respective transport belt over the entire length of the tread 15 against the tread 15. This takes into account that due to the weight of the transport belt 16, this could sag in the direction of the substrate, if a sufficient belt tension is not present.
- the Curvature formed by the respective Hohlpro fil 4 itself.
- the curvature is formed by the attached to the respective Hohlpro fil 4 guide profile 39, which forms the tread 15 on the Hohlpro fil 4.
- the passage openings 14 are further developed as through-holes in the guide profile 39, as can also be seen in FIG. 1, thereby connecting the respective longitudinal groove 21 with the vacuum chambers 10, 11 and 12.
- the vacuum chambers 10, 11, 12 and the passage openings 14 in the hollow profile 4 are thus not directly, but indirectly connected by the guide profile 39 with the tread 15 and the transport belt 16.
- the transport belts 16 on the upper side of the support structure 3 essentially run freely, so that frictional forces are minimized.
- To guide the transport belt 16 on the top of optional lateral guide rollers 37 are provided which are assigned to the respective transport belt 16 on both sides, so that it is felt between them.
- the transport rollers 37 are expediently distributed uniformly over the longitudinal extent of the support structure 3 on the upper side in order to ensure a secure transport belt guide.
- FIGS. 6A and 6B show in two simplified perspective sectional views of one of the hollow sections 4.
- the section extends along the longitudinal extent of the hollow section 4, so that it passes through the hollow chamber 25, the fürgangsöffhungen 14 and the longitudinal groove 21.
- FIG. 6A shows a view of the cut surface and
- FIG. 6B shows the outside of the hollow profile 4.
- the through-openings 14 are not formed as through-holes, but rather as elongated holes in order to allow a larger volume flow.
- a further transverse bore 40 is formed, which extends parallel to the passage openings 14 in the hollow chamber 25 and thereby longitudinal groove 21 and hollow chamber 25 connect to each other.
- the previously mentioned separating element 24 is arranged in the hollow chamber 25 and has a cross-section of the hollow chamber 25 adapted outer contour, as already mentioned above.
- the separating element 24 has, along its circumferential circumferential surface, a groove 41 which extends in the circumferential direction over the entire separating element 24.
- a sealing compound in particular a permanently elastic hardening silicone, introduced into the hollow chamber 25 through the transverse bore 40, so that the sealant along the groove 41 of the partition member 24 is distributed in the hollow chamber 25 and thereby existing spaces between separating element 24 and the inside of the hollow chamber 25th securely closes.
- a secure seal of the adjacent vacuum chambers 10, 11, 12 ensures each other in a simple manner.
- the further separating element 26 is inserted into the transverse bore 40, which separates the longitudinal groove 21 according to the arrangement of the vacuum chambers 10, 11, 12 from each other to obtain the different areas along the tread 15, as previously mentioned.
- the separating element 26 can be designed as a separate separating element.
- the sealing compound 45 can be introduced through the transverse bore 42 past the fastening screw 43 or before the fastening screw 43 is inserted into the groove 41 and optionally emerge again through the transverse bore 40, which then forms an outlet opening 46 for the sealing compound 45, around the sealing element 26 to build.
- the filling holes for the sealant can then be closed by fastening screws or sealing screws.
- a further transverse bore, in particular threaded bore in the Hohlpro fil 41 may be formed through which the sealant can escape during filling again.
