Description

[0001] The present invention relates to an application device, an automated operating device (robot), a manufacturing system, and a method for joining adhesive tape sections.

[0002] Application devices are known from the prior art. With the aid of these application devices, for example, a one-piece sealing element manufactured by punching is adhered to a substrate. These sealing elements have a lower side and a upper side. In this case, a first primary engagement surface is formed on the lower side, and a second primary engagement surface is formed on the upper side. The sealing element can be adhered to a first substrate via its first primary engagement surface. Subsequently, a second substrate can be adhered to the second primary engagement surface of the sealing element. The two substrates can thus be connected to each other by means of the sealing element. In particular, the one-piece sealing element manufactured by punching can be shaped such that when the first primary engagement surface is connected to the first substrate and the second primary engagement surface is connected to the second substrate, a cavity is formed between the two substrates, which is closed by the two substrates and the sealing element in such a way that the two substrates and the sealing element seal the cavity from the environment of the two substrates and the sealing element.

[0003] Typically, the goal is to provide a particularly advantageous sealing effect in a way that is particularly resource-efficient.

[0004] Therefore, the object of the present invention is to provide a particularly advantageous sealing effect in a particularly resource-efficient manner.

[0005] According to a first aspect of the invention, the aforementioned objective is achieved by an application device having the features of claim 1. This application device is designed for joining tape segments. Each tape segment has a lower tape side and an upper tape side. Furthermore, each tape segment has two adhesive (adhesive) main engagement surfaces extending parallel to each other, a first main engagement surface formed by the lower tape side and a second main engagement surface formed by the upper tape side. Each tape segment also extends from a first end to a second end. A first end engagement surface of adhesive (adhesive) arranged transversely to the main engagement surfaces is disposed at the first end. A second end engagement surface of adhesive (adhesive) arranged transversely to the main engagement surfaces is disposed at the second end. The first end engagement surface and the second end engagement surface also extend from the first main engagement surface to the second main engagement surface. Furthermore, the application device has a retainer assembly. The retainer assembly has retaining devices movable relative to each other. Each retaining device can retain one tape segment, such that the first main engagement surface, the first end engagement surface, and the second end engagement surface of the main engagement surfaces of the tape segment are exposed. The retainer assembly is movable between a receiving position and an application position. The retaining device is movable between a first engagement configuration and a second engagement configuration by means of an actuator. In the first engagement configuration, the retaining device is arranged such that when each retaining device holds one tape segment, the tape segments are arranged spaced apart from each other. In the second engagement configuration, the retaining device is arranged such that when each retaining device holds one tape segment, each first end engagement surface bears against a second end engagement surface in such a way that the first end engagement surface abuts against each second end engagement surface, the first main engagement surface faces the application direction, and the tape segments form a continuous and closed adhesive tape web.

[0006] The application device is designed for joining tape segments. The application device can be attached to the frame of an automated operating device. Specifically, it provides that tape segments can be joined by means of the application device, such that they are connected to each other after joining. The tape segments can be segments of tape that have been at least partially picked up from a tape roll and have been separated into segments to form tape segments through separation.

[0007] Each tape segment has a lower tape side and a higher tape side. Therefore, each tape segment has a lower tape side and a higher tape side. In the case where the tape segment is a tape segment that has been at least partially unrolled from the tape roll and has been at least partially separated into segments to form the tape segment by separation, before unrolling and before separation, the lower tape side of the tape segment may be radially inward relative to the radial direction of the tape roll and the upper tape side of the tape segment may be radially outward relative to the radial direction of the tape roll.

[0008] Furthermore, each tape segment has two parallel adhesive primary bonding surfaces, with the first primary bonding surface formed on the underside of the tape and the second primary bonding surface formed on the topside. The adhesive properties of the primary bonding surfaces ensure that a cohesive bond can be established between the primary bonding surfaces and the surface of the object when one of the primary bonding surfaces abuts against the surface of an object, such as a substrate. A tape segment with two parallel adhesive primary bonding surfaces (the first primary bonding surface formed on the underside of the tape and the second primary bonding surface formed on the topside) can also be referred to as a section of double-sided tape.

[0009] Furthermore, each tape segment extends from a first end to a second end. Specifically, each tape segment extends from the first end toward the second end in a longitudinal direction. The longitudinal extent of each tape segment is preferably greater than the perpendicular extent of each tape segment. Particularly preferably, the longitudinal extent of each tape segment corresponds to at least twice the perpendicular extent of the tape segment.

[0010] A first end-joining surface of the adhesive, arranged transversely to the main joining surface, is disposed at the first end. The adhesive properties of the first end-joining surface ensure that a cohesive bond can be established between the first end-joining surface and the surface of the object when the first end-joining surface abuts against the surface of the object, such as the surface of the substrate. In conjunction with the invention, the adhesive properties of the first end-joining surface particularly ensure that a cohesive bond can be established between the first end-joining surface and the second end-joining surface. In particular, due to the adhesive properties of the first end-joining surface, a cohesive bond can be established between the first end-joining surface of the first tape segment and the second end-joining surface of the second tape segment. This is particularly applicable to each tape segment, such that each first end-joining surface of the tape segment abuts against the second end-joining surface of the tape segment, such that the first end-joining surface abuts against each second end-joining surface, and in particular, due to the adhesive properties of the first end-joining surfaces in each pair of adjacent tape segments, particularly within a continuous and closed tape web, a cohesive bond can be established between the first end-joining surface of the first tape segment of each pair of adjacent tape segments and the second end-joining surface of the second tape segment of that pair of adjacent tape segments. This cohesive bonding ensures a seal and prevents fluid communication between the first and second end-joining surfaces of two adjacent tape segments in the adhesive tape web.

[0011] The first end-joining surface is arranged transversely to the main joint surface. Specifically, because the first end-joining surface is arranged transversely to the main joint surface, each of the main joint surfaces forms an angle of less than 180° with the first end-joining surface. Preferably, the first end-joining surface is arranged transversely to the main joint surface such that it forms a 90° angle with each of the main joint surfaces. In this case, it is preferable that the first end-joining surface has a surface normal extending in the longitudinal direction of the tape segment. Alternatively, the first end-joining surface may have a surface normal extending at an angle to the longitudinal direction of the tape segment. Particularly preferred is that the first end-joining surface is arranged transversely to the main joint surface such that it forms a 90° angle with each of the main joint surfaces, and the surface normal of the first end-joining surface extends at a 45° angle to the longitudinal direction of the tape segment.

[0012] A second end-joining surface of the adhesive, arranged transversely to the main joint surface, is disposed at the second end. The adhesive properties of the second end-joining surface ensure that a cohesive bond can be established between the second end-joining surface and the surface of the object when the second end-joining surface abuts against the surface of the object, such as the surface of the substrate. In conjunction with the invention, the adhesive properties of the second end-joining surface particularly ensure that a cohesive bond can be established between the second end-joining surface and the first end-joining surface. In particular, due to the adhesive properties of the second end-joining surface, a cohesive bond can be established between the first end-joining surface of the first tape segment and the second end-joining surface of the second tape segment. This is particularly applicable to each tape segment, such that each first end-joining surface of the tape segment abuts against the second end-joining surface of the tape segment, such that the first end-joining surface abuts against each second end-joining surface, and particularly, due to the adhesive properties of the second end-joining surfaces in each pair of adjacent tape segments, particularly within a continuous and closed tape web, a cohesive bond can be established between the first end-joining surface of the first tape segment of each pair of adjacent tape segments and the second end-joining surface of the second tape segment of that pair of adjacent tape segments. This cohesive connection ensures a seal and prevents fluid communication between the first and second end-joining surfaces of two adjacent tape segments in the adhesive tape web. In particular, the combination of the adhesive properties of the first and second end-joining surfaces ensures a particularly tight cohesive connection, making it especially effective at preventing fluid communication between the first and second end-joining surfaces of two adjacent tape segments in the adhesive tape web.

[0013] The second end-joining surface is arranged transversely to the main joint surface. Specifically, because the second end-joining surface is arranged transversely to the main joint surface, each of the main joint surfaces forms an angle of less than 180° with the first end-joining surface. The second end-joining surface is preferably arranged transversely to the main joint surface such that it forms a 90° angle with each main joint surface. In this case, it is preferable that the second end-joining surface has a surface normal extending in the negative longitudinal direction of the tape segment. Alternatively, the second end-joining surface may have a surface normal extending at an angle to the negative longitudinal direction of the tape segment. Particularly preferred is that the second end-joining surface is arranged transversely to the main joint surface such that it forms a 90° angle with each main joint surface, and the surface normal of the second end-joining surface extends at a 45° angle to the negative longitudinal direction of the tape segment. The negative longitudinal direction is preferably oriented in a direction opposite to the longitudinal direction, such that when the negative longitudinal direction and the longitudinal direction are represented as vectors, the two vectors are identical except for being oriented in opposite directions, specifically, the two vectors have the same starting point and form a 180° angle between them.

[0014] Furthermore, the first end-joining surface and the second end-joining surface extend from the first main-joining surface to the second main-joining surface. The extent of the first end-joining surface from the first main-joining surface to the second main-joining surface ensures that when the first end-joining surface abuts against the second end-joining surface, the interface between the first end-joining surface and the second end-joining surface extends from the first main-joining surface to the second main-joining surface. Specifically, when a cohesive connection is made between the first end-joining surface and the second end-joining surface, the extent of the first end-joining surface from the first main-joining surface to the second main-joining surface allows the cohesive connection to extend from the first main-joining surface to the second main-joining surface. This cohesive connection from the first main-joining surface to the second main-joining surface ensures, particularly when the first main-joining surface is connected to the first substrate and the second main-joining surface is connected to the second substrate, a seal can be provided for the entire area between the first main-joining surface and the second main-joining surface. Specifically, the sealing of the entire area between the first and second main joint surfaces between the two tape segments in the region of the first end joint surface of the first tape segment and the second end joint surface of the second tape segment ensures a reliable seal between the cavity between the two substrates and the environment in the region between the two tape segments.

[0015] The second end-joining surface also extends from the first main-joining surface to the second main-joining surface. The extent of the second end-joining surface from the first main-joining surface to the second main-joining surface ensures that when the second end-joining surface abuts against the first end-joining surface, the interface between the first and second end-joining surfaces extends from the first main-joining surface to the second main-joining surface. Specifically, the extent of the second end-joining surface from the first main-joining surface to the second main-joining surface allows for a cohesive connection to extend from the first main-joining surface to the second main-joining surface when a cohesive connection is made between the first and second end-joining surfaces. This cohesive connection between the first and second main-joining surfaces ensures a seal is provided for the entire area between the first and second main-joining surfaces when the first main-joining surface is connected to the first substrate and the second main-joining surface is connected to the second substrate. In particular, the sealing of the entire area between the first and second main-joining surfaces of the two tape segments in the region of the first end-joining surface of the first tape segment and the second end-joining surface of the second tape segment ensures a reliable seal between the cavity between the two substrates and the environment in the region between the two tape segments.

[0016] Furthermore, the application device includes a retainer assembly. The retainer assembly includes retaining devices. The retaining devices are movable relative to each other. The retaining devices can therefore move relative to each other. Additionally, the retainer assembly may have a baseplate in which a guide is provided for each retaining device, along which the corresponding retaining device can move. As already described, the application device can be attached to the frame of the automated operating device. For example, the automated operating arm of the automated operating device can be attached to the frame of the automated operating device, and the automated operating arm can in turn be attached to the baseplate, thereby enabling the application device to move with the assistance of the automated operating arm.

[0017] Each retaining device holds one segment of tape, exposing the first primary engagement surface, the first end engagement surface, and the second end engagement surface of the tape segment's main engagement surface. Because each retaining device can hold one segment of tape, exposing the first primary engagement surface, the first end engagement surface, and the second end engagement surface, it ensures that each tape segment held by the retaining device can contact the surface of the object with its first primary engagement surface, its first end engagement surface, and its second end engagement surface. The ability of each retaining device to hold the corresponding tape portion in a manner that exposes the first primary engagement surface, the first end engagement surface, and the second end engagement surface allows the tape segment to connect with the surface of the first substrate with its first primary engagement surface, with the second end engagement surface of another tape segment with its first end engagement surface, and with the first end engagement surface of another tape segment with its second end engagement surface, particularly when the tape segment is held by the retaining device.

[0018] The retainer assembly is movable between a receiving position and an application position. In the receiving position, a tape segment is received by the retainer assembly by means of a retaining device, such that each retaining device holds one tape segment after it has been picked up. Upon receiving a tape segment, the retainer assembly can move from the receiving position to the application position. In the application position, the tape segment can be applied to the substrate by means of the retainer assembly, as the retaining device presses the tape segment onto the substrate and then releases the tape segment, such that the tape segment remains on the substrate when the retainer assembly moves back from the application position.

[0019] The retaining device can be moved between a first engagement configuration and a second engagement configuration by means of an actuator. This allows the retaining device to move from the first engagement configuration to the second engagement configuration and from the second engagement configuration to the first engagement configuration. The application device has an actuator for moving the retaining device. The application device may also have multiple actuators for moving the retaining device. One actuator of the multiple actuators may be assigned to each retaining device, for example, such that the retaining devices can move independently relative to each other. One or more actuators may have a pneumatic cylinder. One or more actuators may be connected to a substrate.

[0020] In the first engagement configuration, the retaining devices are arranged such that when each retaining device holds one segment of tape, the tape segments are spaced apart from each other. This arrangement in the first engagement configuration, where the tape segments are spaced apart from each other while each retaining device holds one segment of tape, means that the tape segments can be received without contacting each other. Therefore, cohesive adhesion (bonding) between the tape segments is avoided in the first engagement configuration. Specifically, it is specified that the retaining devices are in the first engagement configuration when the retainer assembly is in the receiving position.

[0021] In the second joining configuration, the retaining devices are arranged such that when each retaining device holds one tape segment, each first end joining surface abuts against a second end joining surface, with the first main joining surface facing the application direction, and the tape segments form a continuous and closed tape web. The second joining configuration ensures that the tape segments join together, forming a continuous and closed tape web. Specifically, when the tape segments form a continuous and closed tape web, this continuous and closed tape web can be formed before the retainer assembly is in the application position, before the tape segments abut against the surface of the substrate having the first main joining surface. Therefore, in the second joining configuration, the tape segments can be joined together without adhesive forces from the substrate acting on the first main joining surfaces of the tape segments. In the second joining configuration, the tape segments can also be optimally positioned relative to each other, so that the continuous and closed tape web provides a favorable sealing effect, particularly at the interface between the first end joining surface and the second end joining surface, especially when the continuous and closed tape web is used to seal the cavity between two substrates relative to the environment.

[0022] Because of the fact that each first end-joining surface abuts against a second end-joining surface and each first end-joining surface abuts against a second end-joining surface in the second joining configuration, cohesive connections are formed between pairs of first and second end-joining surfaces of different tape segments, respectively. These cohesive connections ensure a seal between all pairs of first and second end-joining surfaces. Furthermore, in the second joining configuration, the first primary joining surfaces of the tape segments face the application direction. Specifically, the fact that the first primary joining surfaces of the tape segments face the application direction means that, for example, the tape segments can be applied to the surface of the substrate by moving them in the direction of application, thereby cohesively bonding them to the material. Specifically, the fact that the first primary joining surfaces of all tape segments face the application direction means that all tape segments can be applied to the surface of the substrate together, particularly simultaneously. The fact that all tape segments can be applied to the surface of the substrate together, particularly simultaneously, means that the tape segments can be applied to the substrate in a particularly time-efficient manner. Furthermore, in the second joining configuration, the tape segments form a continuous and closed tape web. Therefore, the tape web comprises tape segments, each tape segment having a first end engagement surface abutting a second end engagement surface of a first adjacent tape segment, and a second end engagement surface abutting a first end engagement surface of a second adjacent tape segment. The tape web is continuous. The fact that the tape web is continuous means that, for example, if the tape web is arranged between two substrates, the tape web can close a cavity between the two substrates and the tape web itself. Thus, a continuous tape web can provide a seal between the cavity and the environment, particularly between the tape web and the environments of the two substrates. The tape web is closed. The fact that the tape web is closed means that the tape web forms a cohesive and uninterrupted structure that provides a continuous seal for the cavity relative to the environment. In particular, when the retainer assembly is in the application position, the retaining device is in a second engagement configuration. Preferably, the retaining device initially moves from the first engagement configuration to the second engagement configuration before the retainer assembly moves to the application position.

[0023] In the second joining configuration, the tape segments thus form a continuous and closed tape web, because in the second joining configuration, the first adhesive end joining surface abuts against the second adhesive end joining surface. This creates material adhesion between the tape segments, allowing the tape web to provide a sealing effect comparable to that of integral sealing elements known in the art, manufactured by stamping. In particular, it has been found that the continuous and closed tape web manufactured according to the invention provides a particularly effective seal against dust and fluids such as water, especially when the tape web is arranged between two substrates and materially bonded to them. This is particularly advantageous when the tape web, together with the two substrates, seals a cavity and isolates it from the environment, thereby preventing dust and fluids from the environment from entering the cavity. Compared to integral sealing elements known in the art, manufactured by stamping, the present invention has the particular advantage that tape segments can be used in the present invention, thus avoiding material waste that occurs during the stamping process and making it particularly resource-efficient. Furthermore, the tape web can be formed by a second bonding configuration before the tape segments are applied to the substrate surface, thereby ensuring a favorable sealing effect between the bonding surfaces of the first and second adhesive ends.

[0024] Therefore, the present invention provides a particularly advantageous sealing effect in a particularly resource-efficient manner.

[0025] In one embodiment, each holding device of the holding device has a suction device capable of withstanding a vacuum, such that when the suction device on the second main joint surface side of the main joint surface abuts against the tape segment and is subjected to a vacuum, the holding device holds the tape segment by means of the suction device. Therefore, the suction device can withstand a vacuum. Specifically, the application of vacuum by the suction device can be terminated, thereby ending the holding of the tape segment by means of the holding device. Thus, the tape segment can be held by means of the suction device. Similarly, the tape segment can be released again by means of the suction device after being held.

[0026] In one embodiment, in the second bonding configuration, the tape web extends along a plane perpendicular to the application direction. The fact that the tape web extends along a plane perpendicular to the application direction means that a tape web is provided that can be applied particularly well to a flat surface, such as the flat surface of a substrate.

[0027] In one embodiment, in the second joining configuration, at least one tape web segment is bent such that at least one first end joining surface abuts against a second end joining surface, such that the surface normals of both the first and second end joining surfaces each form an angle with a straight line extending perpendicular to the application direction. The fact that at least one tape web segment is bent in the second joining configuration means that at least partially bent tape webs can be provided. The invention is preferably not limited to continuous and closed tape webs extending along a plane. Rather, the invention also includes tape webs that are designed to be bent and do not extend at least partially (segmentally) along the same plane.

[0028] In one embodiment, in the second bonding configuration, the tape web has a rectangular or square shape when viewed in the direction of application, wherein each side of the rectangle or square is formed by a tape segment. Rectangles and squares each represent particularly simple geometries of the tape web. In particular, when each side of the rectangle or square is formed by a tape segment, the tape web can be easily formed by means of four tape segments. Preferably, when four tape segments are used to form the tape web, a geometry particularly advantageous to the display can be produced in the tape web. Specifically, when four tape segments are used to form the tape web, a particularly simple and mechanically robust structure of the application device and, in particular, the holding device can be selected, because two adjacent holding devices are provided, each of which can move toward and away from each other perpendicularly. Particularly preferably, the holding devices are movable toward each other, providing two holding devices that can move toward and away from each other, and providing two additional holding devices that are stationary relative to the substrate of the holder assembly and cannot move relative to the substrate. This results in a particularly mechanically robust application device, especially since a total of four retaining devices are provided, for which the required guide does not need to be moved for two of the four retaining devices.

[0029] In one embodiment, the application device includes a removal device that can be connected to a protective film of the adhesive layer attached to the tape segment while at least one retaining device holds the tape segment. The protective film can be retained by means of the removal device, particularly when the retainer assembly is removed from the application position, such that the protective film can be separated from the adhesive layer of the tape segment when the tape segment is applied to a substrate.

[0030] In one embodiment, while each retaining device holds a portion of the tape, a removal device can be connected to each protective film of the adhesive layer attached to a segment of the tape. The protective film can be retained by means of the removal device, particularly when the retainer assembly is removed from the application position, such that the protective film can be separated from the adhesive layer of the tape segment when the tape segment is applied to a substrate.

[0031] In one embodiment, the application device includes an output device that can provide tape segments. For example, tape segments can be provided on a carrier belt via the output device. The fact that the application device includes an output device means that tape segments can be provided, in particular, automatically.

[0032] According to a second aspect of the invention, the aforementioned objective is achieved by an automated operating device having the features of claim 9. The automated operating device has a frame and an application device according to the first aspect of the invention mounted on the frame. The automated operating device can be part of a manufacturing system. In particular, the provided automated operating device has an automated operating device arm. The automated operating device arm is preferably attached to the frame of the automated operating device. The automated operating device arm can be attached to the frame of the automated operating device at a first end. At a second end, the automated operating device arm can be attached to the application device, thereby allowing the application device to move relative to the frame. For example, a retainer assembly can be moved between a receiving position and an application position by means of the automated operating device arm.

[0033] The features, technical effects, and / or advantages described in the application device according to the first aspect also apply, at least similarly, to the automatic operating device according to the second aspect of the invention, meaning that there is no need to repeat the description at this point.

[0034] According to a third aspect of the invention, the aforementioned objective is achieved by a manufacturing system having the features of claim 10. This manufacturing system includes an automated operating device according to a second aspect of the invention. In addition to the automated operating device, the manufacturing system may also have other components.

[0035] For example, tape segments can be disposed on a carrier belt via a dispensing device. The presence of a dispensing device in the manufacturing system allows for particularly automated supply of tape segments. Especially when both an output device and a dispensing device are provided, different tape segments, particularly those with different designs, can be easily supplied simultaneously and received together with the retainer assembly, particularly simultaneously, because the tape segments are received together with the retaining device.

[0036] In one embodiment, the manufacturing system includes a camera system that can optically determine the position of each tape segment as each holding device of the holding device holds one tape segment. The optically determined position of each tape segment can be compared with a target position of the tape segment. If the target position deviates from the optically determined position by more than a position threshold, the corresponding tape segment can be released from the holding device, and a new tape segment can be received by the holding device. Similarly, when each holding device holds a tape segment, the camera system can optically determine the orientation of each tape segment. The optically determined orientation of each tape segment can then be compared with a target orientation of the tape segment. If the target orientation deviates from the optically determined orientation by more than an orientation threshold, the corresponding tape segment can be released from the holding device, and a new tape segment can be received by the holding device. Therefore, by means of the camera system, the position and / or orientation of the tape segments can be automatically checked, and the application process can be intervened if necessary. The camera system that can optically determine the position and / or orientation of each tape segment while each holding device of the holding device is holding one tape segment can also be referred to as a first camera system.

[0037] The manufacturing system preferably includes a camera system that can optically determine the position of each tape segment once each tape segment has been provided by an output device or a dispensing device. Similar to the case where each holding device holds one tape segment, the optically determined position of each tape segment can be compared with a target position of the tape segment. In this case, the target position can also be referred to as the target position of the provided tape segment. If the target position deviates from the optically determined position by more than a position threshold, the corresponding tape segment can be removed, and a new tape segment can be provided. More preferably, when each tape segment has been provided by an output device or a dispensing device, the camera system can optically determine the orientation of each tape segment. The optically determined orientation of each tape segment can then be compared with a target orientation of the tape segment. In this case, the target orientation can also be referred to as the target orientation of the provided tape segment. If the target orientation deviates from the optically determined orientation by more than an orientation threshold, the corresponding tape segment can be removed, and a new tape segment can be provided. Therefore, by means of a camera system, the position and / or orientation of the provided tape segments can be automatically checked, and the application process can be intervened when necessary, especially before the tape segments are received and held by the holding device. This allows for particularly time-efficient correction of any incorrect positioning and / or orientation of the provided tape segments if they are provided with incorrect positioning and / or orientation. A camera system that can optically determine the position and / or orientation of each tape segment, provided that each tape segment has been provided by an output device or dispensing device, may also be referred to as a second camera system. Preferably, the first camera system and the second camera system are different, particularly spatially separated, so that the first camera system and the second camera system can be arranged independently of each other.

[0038] In one embodiment, the manufacturing system includes a substrate holder capable of holding a substrate having a substrate surface, wherein when the holder assembly is in the application position and configured with a second assembly, and when the substrate holder holds the substrate, the tape web abuts against the substrate surface with a first primary bonding surface facing the application direction. Specifically, the substrate can be positioned and secured by means of the substrate holder, particularly when the tape web is placed on and pressed against the substrate surface.

[0039] The features, technical effects, and / or advantages described in conjunction with the application device according to the first aspect and the automatic operation device according to the second aspect are also similarly applied to the manufacturing system according to the third aspect of the invention, which means that repetition of the description is omitted at this point.

[0040] According to a fourth aspect of the invention, the above-mentioned object is achieved by a method having the features of claim 14. The method aims to join tape segments by means of an application device according to a first aspect of the invention. Each tape segment has a lower tape side and an upper tape side. Each tape segment has two adhesive main bonding surfaces extending parallel to each other, a first main bonding surface formed by the lower tape side and a second main bonding surface formed by the upper tape side. Each tape segment extends from a first end to a second end, wherein a first end bonding surface of adhesive is provided at the first end, arranged transversely to the main bonding surfaces, and a second end bonding surface of adhesive is provided at the second end, arranged transversely to the adhesive bonding surfaces. The first end bonding surface and the second end bonding surface extend from the first main bonding surface to the second main bonding surface. The method includes the following steps: holding a tape segment by means of a holding device such that for each tape segment, a first main engagement surface, a first end engagement surface, and a second end engagement surface of the main engagement surface of the tape segment are exposed; moving the holding device from a first engagement configuration to a second engagement configuration by means of an actuator, wherein in the first engagement configuration, the holding device is arranged such that when each holding device of the holding device holds a tape segment of the tape segment, the tape segments are arranged to be spaced apart from each other, and in the second engagement configuration, the holding device is arranged such that when each holding device of the holding device holds a tape segment of the tape segment, each first end engagement surface abuts against a second end engagement surface, such that the first end engagement surface abuts against each second end engagement surface, the first main engagement surface faces the application direction, and the tape segments form a continuous and closed tape web.

[0041] In one embodiment, holding the tape segment by means of a holding device includes holding the tape segment by means of a suction device of the holding device, wherein each suction device on the second main bonding surface side of the main bonding surface abuts against the tape segment and is subjected to a vacuum while holding the tape segment.

[0042] In one embodiment, the method includes the steps of: connecting a withdrawal device to a protective film of a tape segment, the protective film being attached to an adhesive layer of the tape segment; ending the holding of the tape segment by means of a holding device; and moving the withdrawal device such that the protective film is peeled off from the adhesive layer in a direction opposite to the application direction.

Figure 2 The first engagement configuration shown is moved to Figure 3 The second engagement configuration shown, and also from, as Figure 3 The second connection configuration shown is moved to Figure 2The first engagement configuration is shown. To move the retaining device 5, the applying device has four actuators. Each retaining device 5 is associated with one of the four actuators, such that the retaining device 5 can move independently of each other. Figure 4 It shows that according to Figure 1 A schematic side view of an embodiment of the application device 1.

[0060] Figure 5 and Figure 6a (a), (b), and (c) show schematic diagrams of tape segment 9, which can be constructed using... Figure 1 The application device 1 according to the invention and the method according to the invention are used for bonding. The tape segment 9 is displayed at different positions during the implementation of the method according to the invention.

[0061] Each tape segment 9 has a lower tape side and a higher tape side. Figure 5 China and in Figure 6a In cases b) and c), the upper side of tape segment 9 is away from the observation direction, and therefore in Figure 5 China and in Figure 6a Seen in (a), (b), and (c). Furthermore, in Figure 5 China and in Figure 6a In (a), (b), and (c), the underside of tape segment 9 faces the viewing direction, and therefore... Figure 5 China and in Figure 6a (a), (b), and (c) are not visible, or are covered by tape segment 9 itself. An application direction is provided as follows: this direction is perpendicular to... Figure 5 The image plane in and perpendicular to Figure 6a The images in (a), (b), and (c) are arranged in planar order and, in each case, face the viewing direction. Therefore, the underside of the tape faces the application direction.

[0062] Each tape segment 9 has two adhesive main bonding surfaces extending parallel to each other. The main bonding surfaces include a first main bonding surface and a second main bonding surface. The first main bonding surface is formed on the underside of the tape. The second main bonding surface is formed on the upper side of the tape. Furthermore, each tape segment 9 extends from a first end 11 to a second end 13. At the first end 11, a first end bonding surface is provided, which is adhesive and arranged transversely to the main bonding surfaces. At the second end 13, a second end bonding surface is provided, which is also adhesive and arranged transversely to the main bonding surfaces. Both the first end bonding surface and the second end bonding surface extend from the first main bonding surface to the second main bonding surface.

Figure 5In the arrangement of the adhesive tape segment 9 shown on the right, the retaining device 5 is in the second engagement configuration. Figure 5 In the arrangement of the tape segment 9 shown in the middle, the retaining device 5 is positioned between the first engagement configuration and the second engagement configuration. During the engagement of the tape segment 9, Figure 5 The retaining device 5 in the arrangement of the tape segment 9 shown in the middle has moved from the first engagement configuration and will next move to the second engagement configuration. Figure 6a In the arrangement of tape segments 9 shown on the left in (a), (b), and (c), the retaining device 5 is in the first engagement configuration, while Figure 6a In the arrangement of the tape segment 9 shown on the right in (a), (b) and (c), the retaining device 5 is in the second engagement configuration.

[0064] Figure 7 A schematic diagram of tape segment 9 is shown, which can be achieved by means of... Figure 1 According to an embodiment of the application device 1 of the present invention, and by means of the method of the present invention, the tape segment 9 is as follows: Figure 7 As shown in the diagram. As described above, each tape segment 9 extends from the first end 11 to the second end 13. Figure 7 The tape segments 9 shown are arranged on the carrier tape 15. Each tape segment 9 has a protective film 17, such as... Figure 7 As shown in the cross-sectional view on the right. As already described, each tape segment 9 has a lower tape side and a higher tape side. A first primary bonding surface is formed by the lower tape side. A second primary bonding surface is formed by the upper tape side. Both the first and second primary bonding surfaces are adhesive. Each of the first and second primary bonding surfaces may each form an area of ​​an adhesive layer (of the same or different kinds). Figure 7 In this process, each tape segment 9 is attached to the carrier tape 15 with a first primary bonding surface. Furthermore, each tape segment 9 is attached to the protective film 17 with a second primary bonding surface. In other words, the protective film 17 is attached to the second primary bonding surface of each tape segment 9. Figure 7 In the example shown, tape segment 9 has an adhesive layer made of acrylic foam. The adhesive layer made of acrylic foam has the advantage that, compared to other adhesive layers, the adhesive properties of acrylic foam can be provided to surfaces of various shapes for corresponding applications, making tape segment 9 with an adhesive layer made of acrylic foam versatile in applications. Therefore, each protective film 17 is attached to the adhesive layer of tape segment 9.

[0065] As previously described, the application device 1 is designed to engage tape segments 9. The application device 1 includes a retainer assembly 3. The retainer assembly 3 is movable between a receiving position and an application position. In the receiving position, tape segments 9 can be received from the retainer assembly 3 by means of retaining devices 5, such that once a tape segment 9 has been received, each retaining device 5 holds one tape segment 9. The retaining devices 5 can withstand a vacuum to hold the tape segments 9. A vacuum generator, such as a vacuum pump, can be provided for applying a vacuum. The retaining devices 5 hold the tape segments 9 by means of the suction device 7 when the suction device 7 abuts against the tape segment 9 from the second main engagement surface side and is subjected to a vacuum. Using the received tape segments 9, the retainer assembly 3 can move from the receiving position to the application position. In the application position, tape segments 9 can be applied to the substrate by means of the retainer assembly 3, as the retaining devices 5 press the tape segments 9 onto the substrate and then release the tape segments 9, such that when the retainer assembly moves backward from the application position, the tape segments 9 remain on the substrate.

[0066] As previously described, the retainer assembly 3 also has four retaining devices 5, which are movable relative to each other. Each retaining device 5 retains the tape segment 9 such that the first main engagement surface, the first end engagement surface, and the second end engagement surface of the tape segment 9 are exposed. The retaining devices 5 can be moved between the first engagement configuration and the second engagement configuration by means of an actuator.

[0067] In the first engagement configuration, the retaining devices 5 are arranged such that when each retaining device 5 holds a tape segment 9, the tape segments 9 are spaced apart from each other. Specifically, when the retainer assembly 3 is in the receiving position, the retaining devices 5 are in the first engagement configuration. As previously described, Figure 2 The retaining device 5 in the first engagement configuration is shown. Similarly, as previously described, Figure 5 The arrangement of the tape segment 9 shown on the left illustrates the retaining device 5 in the first engagement configuration. Furthermore, as previously described, Figure 6a The arrangement of tape segments 9 shown on the left in (b) and (c) also shows the case where the retaining device 5 is in the first engagement configuration.

[0068] In the second engagement configuration, the retaining device 5 is arranged such that when each retaining device 5 holds the tape segment 9, each first end engagement surface abuts against a second end engagement surface, such that the first end engagement surface abuts against each second end engagement surface, the first main engagement surface faces the application device, and the tape segment 9 forms a continuous and closed tape web. Specifically, when the retainer assembly 3 is in the application position, the retaining device 5 is in the second engagement configuration. Specifically, in conjunction with the invention, the retaining device 5 first moves from the first engagement configuration to the second engagement configuration, and then the retainer assembly 3 moves to the application position. As previously stated, Figure 3The retaining device 5 in the second engagement configuration is shown. Similarly, as previously described, Figure 5 The arrangement of tape segment 9 shown on the right side illustrates the second engagement configuration of the retaining device 5. Furthermore, as previously described, Figure 6a The arrangement of tape segment 9 shown on the right in (b) and (c) also illustrates the case where the retaining device 5 is in the second engagement configuration. Figure 5 , 6a) In 6b) and 6c), in the right-hand representation of their respective cases, the adhesive tape web extends along a tape plane perpendicular to the application direction. Specifically, in the second bonding configuration, at least one tape web segment can be bent such that at least one first end bonding surface abuts against a second end bonding surface, such that both the surface normals of the first and second end bonding surfaces form an angle with a straight line extending perpendicular to the application direction. Figure 5 The right side of the diagram indicates that, viewed from the direction of application, the tape web has a rectangular shape. Each side of the rectangle is formed by tape segments 9, which constitute a continuous and closed adhesive tape web 9. Figure 6a) , 6b) As shown on the right side of (6c), when viewed from the direction of application, each adhesive tape web has a square shape. Each side of the corresponding square is formed by a tape segment 9. Here, each tape segment 9 also forms a continuous and closed tape web 9.

[0069] As already described, the application device 1 may include a extraction device. When at least one retaining device 5 holds the tape segment 9, the extraction device may be connected to a protective film 17 of the tape segment 9, which is attached to the adhesive layer of the tape segment 9. For example, each retaining device 5 may have an extraction element 7a of the extraction device, which is movable together with the retaining device 5. When the retaining device 5 assigned to each extraction element 7a holds the tape segment 9, each extraction element 7a may be connected to the protective film 17 of the tape segment 9. In particular, the application device 1 may include an extraction device that, when each retaining device 5 holds the tape segment 9, is connected to the protective film 17 attached to the adhesive layer of the tape segment 9. One or more protective films 17 may be held by means of the extraction device or by means of the extraction element 7a, particularly when the retainer assembly 3 is moved out of the application position, such that when the tape segment 9 is applied to the substrate, the adhesive layer of one or more tape segments 9 can be released.

[0070] As mentioned above, Figures 1 to 4The described implementation includes a vacuum generator, by which the suction holders can be subjected to vacuum independently of each other. Specifically, the suction holders that do not form the extraction element 7a and the suction holders that do form the extraction element 7a can be subjected to vacuum independently of each other. This allows the application of vacuum to the suction holders that do not form the extraction element 7a to be terminated first, and then the application of vacuum to the suction holders that form the extraction element 7a to be terminated. Specifically, when the retainer assembly 3 is in the applied position, the application of vacuum to the suction holders that do not form the extraction element 7a can be terminated first. When the retainer assembly 3 is in the applied position, the application of vacuum to the suction holders that form the extraction element 7a has not yet been terminated. When the retainer assembly 3 has been removed from the application position, the vacuum applied to the suction holder forming the extraction element 7a can be terminated, so that a protective film 17 or more protective films 17 separated from the adhesive layer of one or more tape segments 9 are released and discarded by removing the retainer assembly 3 from the application position and applying vacuum to the suction holder forming the extraction element 7a.

[0071] As described above, the application device 1 may include an output device (not shown). The output device may provide a tape segment 9. For example, the tape segment 9 may be provided on the carrier tape 15, such as... Figure 7 As shown in the diagram. Additionally or alternatively, the manufacturing system may include a dispensing device, not shown. The dispensing device may also provide tape segments 9. In particular, the fact that both an output device and a dispensing device are available means that, with both an output device and a dispensing device provided, different tape segments 9, especially those of different shapes, can be readily provided simultaneously and received together, especially simultaneously, from the retainer assembly 3, because the tape segments 9 are received together, especially simultaneously, by the retaining device 5.

[0072] Furthermore, the manufacturing system, including an automated operating device with a frame and an application device attached to the frame, may have a camera system (not shown). When each of the holding devices 5 holds a segment of tape 9, the camera system can optically determine the position of each segment of tape 9. The optically determined position of each segment of tape 9 can then be compared with a target position of the segment of tape 9. If the target position deviates from the optically determined position by more than a position threshold, the corresponding segment of tape 9 can be released from the holding device 5, and a new segment of tape can be received by the holding device 5. Similarly, when each holding device 5 holds a segment of tape 9, the camera system can optically determine the orientation of each segment of tape 9. The optically determined orientation of each segment of tape 9 can then be compared with a target orientation of the segment of tape 9. If the target orientation deviates from the optically determined orientation by more than an orientation threshold, the corresponding segment of tape 9 can be released from the holding device 5, and a new segment of tape can be received by the holding device 5. Therefore, by means of the camera system, the position and / or orientation of the segments of tape 9 can be automatically checked, and the application process can be intervened when necessary. Furthermore, the manufacturing system may include a substrate holder (not shown). The substrate holder holds the substrate having a substrate surface. When the holder assembly 3 is in the application position and in the second engagement configuration, and when the substrate holder holds the substrate, the tape web abuts against the substrate surface with the first main engagement surface facing the application direction.

[0073] As previously described, by implementing the method according to the invention, tape segments 9 can be joined by means of an application device 1. In one embodiment, the method according to the invention includes the following steps: First, a substrate having a substrate surface is provided. The provided substrate is moved to a substrate holder. The substrate is then held by means of the substrate holder. The tape segment 9 is then provided by means of an output device or a dispensing device. The holding device 5 is moved to a first joining configuration by means of an actuator. The holder assembly 3 is moved to a receiving position to receive the tape segment 9. When the holder assembly 3 is in the receiving position, each suction device 7 is arranged on the second main joining surface side of the tape segment 9. Each suction device 7 abuts against the corresponding tape segment 9 from the second joining surface side and has a vacuum applied thereto. Applying a vacuum to the suction device 7 ensures that the tape segment 9 is held by means of the holding device 5. The tape segment 9 is held by means of the holding device 5 such that for each tape segment 9, the first main joining surface, the first end joining surface, and the second end joining surface of the tape segment 9 are exposed. Next, the extraction device is connected to the protective film 17, each of which is attached to the adhesive layer of the tape segment. In this exemplary embodiment, each extraction element 7a formed by the suction holder contacts the corresponding protective film 17, and then a vacuum is applied to each extraction element 7b.

[0074] Next, the retainer assembly 3 moves out of the receiving position. When the retainer assembly 3 moves out of the receiving position, the tape segment 9 is held by means of the retaining device 5. In this case, the retaining device 5 is in a first engagement configuration, wherein the retaining device 5 is arranged such that the tape segments 9 are spaced apart from each other. By arranging the tape segments 9 spaced apart from each other, it is ensured that the tape segments 9 do not contact each other. When the retainer assembly 3 moves out of the receiving position, the tape segment 9 moves by means of the applying device 1.

[0075] Specifically, before the retainer assembly 3 is in the application position, the retaining device 5 is moved to the second engagement configuration. In the second engagement configuration, the retaining device 5 is arranged such that each of the first end engagement surfaces abuts against a second end engagement surface. Furthermore, in the second engagement configuration, the retaining device 5 is arranged such that the tape segments 9 form a continuous and closed adhesive tape web. The second engagement configuration ensures that the tape segments 9 are joined together, forming a continuous and closed adhesive tape web. Specifically, the fact that the tape segments 9 form a continuous and closed tape web before the retainer assembly 3 is in the application position means that a continuous and closed tape web can be formed before the tape segments 9 are on the substrate with their first main engagement surfaces. This means that the tape segments 9 can be joined to each other in the second engagement configuration without adhesive forces from the substrate acting on the first main engagement surfaces of the tape segments 9. Furthermore, in the second joining configuration, the tape segments 9 can be optimally positioned relative to each other, so that the continuous and closed adhesive tape web has an advantageous sealing effect, particularly at the interface between the first end joining surface and the second end joining surface, especially when the continuous and closed tape web is used to seal the cavity between two substrates in an environmentally friendly manner.

[0076] When the holding device 5 is in the second engagement configuration, the camera system is used to optically determine the position of each tape segment 9. Then, the retainer assembly 3 moves along the application direction to the application position, such that the tape web abuts against the substrate surface with its first main engagement surface facing the application direction. Next, a vacuum is applied by the suction device 7, thereby ending the holding of the tape segment 9 by means of the holding device 5. The retainer assembly 3 is then removed from the application position. During this time, the extraction device moves in such a way that the protective film 17 peels off from the adhesive layer of the tape segment 9 in the direction opposite to the application direction. The vacuum applied to the suction clamp forming the extraction element 7a can then be stopped to release the protective film 17.

[0077] Figure 8 A schematic diagram of a tape segment (9) is shown, which can be used by means of... Figure 1The application device (1) according to the invention is used to join the tape segments (9) by means of the method according to the invention. At least one joining surface of the tape segment (9) is configured by an edge and / or a curve, such that it has an uneven and enlarged surface (19), wherein the opposite joining surface of another tape segment (9) has a corresponding joining surface, such that the two tape segments (9) are joined together to fit perfectly. The joining surface can be semi-circular or arc-shaped, triangular, trapezoidal or serrated. A variety of possible shapes exist. By extending the gap line between the joining surfaces, the sealing of the bonded material described is improved for each pair of adjacent tape segments (9). In principle, it can be said that the more complex the gap line, the less fluid communication between the first end joining surface and the second end joining surface of two adjacent tape segments (9) in the adhesive tape web.

It should also be noted that features described with reference to one of the exemplary embodiments described above may also be used in combination with other features of the other exemplary embodiments described above.
