Description

[Technical Field]

[0001] The present invention relates to a feeding device for feeding components to a surface mount machine for mounting substrates using at least one component belt. The present invention also relates to a component cassette including a component reel with a component belt and a feeding device. The present invention also relates to a transport method for transporting a component belt by the feeding device, particularly after cutting the component belt. [Background technology]

[0002] Surface mounting machines currently widely known in the prior art often employ a component belt for supplying components. The components are stored in the component belt, in particular in pockets on the component belt, and are often protected from falling and / or environmental influences by a film, in particular a protective film and / or a cover film. The component belt is mainly advanced by a supply device (a so-called feeder). The supply device may be configured as a component cassette together with a component reel, or may be configured independently of the component reel. The component belt is advanced by the supply device, which supplies the components to the surface mounting machine for pick-up.

[0003] For handling the feeder, particularly for removal and / or replacement, it is advantageous to be able to cut off the empty, advanced component belt. Cutting devices provided for this purpose are often configured as components of the feeder, as components of the surface mount machine, or separately. Cutting the component belt results in a free end of the component belt, which, in the absence of a clearly demarcated arrangement, guide, or manual operation, can actually become pinched when loading the feeder into a subsequent surface mount machine, thereby interfering with the operation of the feeder.

[0004] From DE 10 200 043 133 A1 it is known how to return the component belt after cutting, thereby avoiding pinching of the free end of the component belt, however the component belt is still disadvantageously guided in an ill-defined manner through a danger zone, which can lead to unintended displacement and / or warping of the component belt during return.

[0005] In particular, feeding devices are known that are configured to peel a protective film from a component belt, thereby feeding components for a pick-up and / or positioning device of a surface mount machine. Peeling the protective film often creates forces on the component belt. Returning a component belt with a protective film, especially a tensioned protective film, can further increase unintended shifting and / or warping of the component belt and protective film during return.

[0006] [Patent Document 1] European Patent Application Publication No. 3806606 Summary of the Invention [Problem to be solved by the invention]

[0007] It is therefore an object of the present invention to overcome or at least partially overcome the above-mentioned drawbacks of prior art feeding devices for feeding components to a surface mounting machine. In particular, it is an object of the present invention to provide a feeding device that particularly facilitates the feeding of components to a surface mounting machine for mounting boards using at least one component belt. In particular, it is also an object of the present invention to provide a component cassette and a transport method for transporting the component belt by the feeding device. [Means for solving the problem]

[0008] The above-mentioned problem is solved by the claims. In particular, the problem is solved by a feeding device for feeding components to a surface mounting machine for mounting substrates by means of at least one component belt, with the features of independent claim 1. Furthermore, the problem is solved by a component cassette comprising a component reel with a component belt and a feeding device, with the features of independent claim 11, and by a transport method for transporting the component belt by means of the feeding device, with the features of independent claim 12. Further advantages and details of the invention emerge from the dependent claims, the description and the drawings. Here, features described in relation to the feeding device according to the invention obviously also apply in relation to the component cassette according to the invention and the transport method according to the invention, and vice versa, so that reference is or can always be made to each other in the disclosure of the respective aspects of the invention.

[0009] According to a first aspect of the present invention, the object is achieved by a feeding device for feeding components to a surface mount machine for mounting substrates using at least one component belt, the feeding device having a drive device for advancing and reversing the component belt and at least one presser device for pressing the component belt when the component belt is reversing.

[0010] The cutting of the component belt is preferably performed in an empty section of the component belt from which components have already been removed by the surface mounting machine. The cutting device provided for this purpose is configured as a component of the feeding device, as a component of the surface mounting machine, or separately. Preferably, the feeding device has a pickup window and / or pickup position for picking up the components by the surface mounting machine. The cutting preferably occurs behind the component pickup position along the conveying direction of the component belt. The cutting results in a free end of the component belt, which preferably roughly corresponds to the distance between the pickup window and the cutting device. This free end is not useful for further handling of the feeding device, for example, for replacing the feeding device. Therefore, the drive device enables the component belt to be retracted. Preferably, the drive device is configured as a drive wheel. Preferably, the drive device is at least partially meshed with the component belt to advance and retract the component belt. The component belt is preferably arranged on a component reel.

[0011] The retraction of the component belt is preferably understood to mean at least partially winding the component belt onto a component reel. The advancement of the component belt by the drive device is preferably understood to mean unwinding the component belt from, for example, a component reel. However, since the retraction of the component belt preferably means pushing the component belt toward the exemplary component reel, the component belt would tend to unintentionally warp if no guide were present. The at least one pressure device according to the present invention advantageously makes it possible to hold down the component belt during retraction. In other words, the at least one pressure device allows at least partial guiding of the component belt during retraction, particularly vertical guiding. In this case, vertical guiding is preferably understood to mean guiding along the vertical axis of the component belt and / or the feed device. The component belt preferably has an upper surface and a lower surface along the vertical axis, and the components are preferably arranged in and / or on the upper surface of the component belt. The advancement direction of the component belt preferably extends at an angle, particularly a right angle, to the vertical axis. To be clear, the pressure device preferably allows the components belt to be pressed down in the height direction of the components belt. The at least one pressure device is preferably arranged laterally of the drive and / or in the region of the drive, thereby enabling advantageous guidance in the region of force introduction from the drive to the components belt. The at least one pressure device is preferably understood as a guide for the components belt at least in the vertical direction and / or a limiter of the component belt's degree of freedom of movement. The at least one pressure device is preferably arranged at a small distance from the components belt to allow the components belt to advance unaffected. Preferably, the at least one pressure device is arranged in such a way that contact with the components belt only occurs upon retraction and / or slight deflection of the components belt. The pressing of the components belt can therefore include permanent, temporary and / or partial contact of the components belt by the at least one pressure device.The at least one hold-down device is preferably configured as a retrofit solution for existing feed devices and / or as an assembly that is at least partially integrated in and / or on the feed device.

[0012] The feeding device preferably comprises a lower guide surface and / or guide device over which the parts belt passes, in particular during forward movement, and / or by which the parts belt is supported, and the parts belt is preferably pressed against and / or in connection with the lower guide surface and / or guide device.

[0013] Components are preferably understood to be electrical, electronic and / or SMD components for mounting on a substrate.

[0014] A supply device of such a construction is particularly advantageous, since it advantageously allows the cutting and retraction of the component belt, and by means of the at least one pressure device it is particularly easy to hold down the component belt when it is retracted.

[0015] According to a preferred further development of the invention, it may be provided that the supply device includes a cutting device and / or a film winding device for cutting the component belt, the film winding device is configured to wind up a protective film on the component belt, and at least one pressing device is configured to press down both the component belt and the protective film when the component belt is retracted.

[0016] As mentioned above, the cutting device may be configured as a component of the feeding device, as a component of the surface mounter, or separately. Preferably, the cutting device in this embodiment of the feeding device is configured as a component of the feeding device. A protective film within the scope of the present invention is understood to be a film for protecting, fixing the position of, and / or covering components in and / or on the component belt. The film winding device is preferably actively or passively driven to wind up the protective film. For example, the film winding device may be driven by applying an elastic force and / or by a drive device of the feeding device.

[0017] As mentioned above, the film winding device and / or the protective film often generate additional force components on the components belt, which can intensify the warping of the components belt when retracted by the drive device. Due to the tension on the protective film, the components belt can be transported by the drive device at a length greater than the protective film when retracted. Even slight differences in the transported lengths increase the likelihood of the components belt warping. It is particularly advantageous if the at least one pressure device can hold down both the components belt and the protective film when the at least one pressure device retracts the components belt. A supply device with such a configuration is particularly advantageous because it advantageously allows the components belt to be cut and retracted, and it is particularly easy to hold down the components belt and the protective film when the at least one pressure device retracts the components belt.

[0018] According to a preferred further development of the invention, it may be provided that the supply device includes a tensioning device for pretensioning the film winding device for winding the protective film and / or is configured to be mechanically operatively connected to a drive device for synchronizing the advancement and retraction of the components belt with the advancement and retraction of the protective film. Particularly preferably, the supply device according to the invention at least partially eliminates and / or reduces the pretension of the film winding device by the tensioning device. This advantageously allows the wound protective film to be removed for retraction of the components belt. Synchronizing the film winding device, the tensioning device, and / or the drive device in combination with at least one pressure device according to the invention at least partially advantageously allows cutting and retraction of the components belt, and the at least one pressure device particularly facilitates the holding down of the components belt and the protective film during retraction of the components belt.

[0019] According to a preferred further development of the invention, it may be provided that the feeder, in particular the drive, is configured to advance the component belt in a forward direction and retract the component belt in a direction opposite to the forward direction, and that at least one pressure device is arranged in front of the drive along the forward direction and / or adjacent, in particular directly adjacent, to the drive. The arrangement of the at least one pressure device relative to the drive and / or within the feeder crucially determines the functionality of the at least one pressure device. Preferably, the at least one pressure device is arranged so that its distance from the component belt decreases at least partially in the direction opposite to the forward direction. Preferably, the at least one pressure device is arranged adjacent, in particular directly adjacent, to the drive and / or in the region of the drive to enable advantageous guidance of the force introduction area from the drive to the component belt. Arranging the at least one pressure device adjacent to the drive device, in particular directly adjacent to it, is understood to mean that the at least one pressure device is preferably arranged near the point of introduction of force from the drive device onto the parts belt, thereby making it possible to advantageously press down the parts belt when it is retracted and / or, conversely, to avoid or at least reduce unfavorable slippage and / or warping of the parts belt when it is retracted. The at least one pressure device, by virtue of its arrangement in the feed device and / or in relation to the drive device, therefore advantageously makes it possible to advantageously guide the parts belt and / or to prevent and / or at least reduce slippage and / or warping of the parts belt when it is retracted by the drive device.

[0020] According to a preferred further development of the invention, it may be provided that, with respect to the feeding device, at least one pressure device includes at least one, preferably at least two, pressure elements, and the at least one pressure element is configured to press down on a peripheral region of the component belt adjacent to the component. The at least one pressure device preferably presses down on the component belt without contact with the components in the component belt, or at least with as little contact as possible. Particularly preferred, the pressure on the component belt is achieved by contacting the component belt at one or both peripheral regions of the component belt. In a preferred embodiment, the at least one pressure device is configured U-shaped, at least partially bipartite, and / or with at least two pressure elements, thereby enabling pressing down on the peripheral region of the component belt and / or forwarding of the component through the pressure elements. The pressure element is specifically understood to be, for example, a pressure arm, which preferably simultaneously enables pressing down on the component belt and passing of the component through the component belt. The peripheral region of the components belt is preferably understood as the edge of the components belt and / or the region adjacent to the edge along the length of the components belt. A feed device constructed in this manner is particularly advantageous, since this configuration of the at least one pressure device advantageously allows the components belt to be cut and retracted, and furthermore, the at least one pressure device particularly easily allows the components belt to be pressed down during retraction.

[0021] According to a preferred further development of the invention, it may be provided that, with respect to the supply device, at least one pressure device is at least partially elastically, integrally, and / or monolithically configured to hold down the components belt. Pressure on the components belt during retraction is particularly advantageously possible if the at least one pressure device is at least partially elastically, integrally, and / or monolithically configured. The at least one pressure device is, for example, at least partially configured as a spring device, in particular a spring device with at least two spring arms. The at least one elastic pressure device advantageously allows for flexible contact and pressure on the components belt during retraction. The integral and / or monolithic design of the at least one pressure device advantageously allows for stable, low-cost production and simplified assembly. The at least one pressure device is preferably at least partially integrated into the supply device and / or fixed to the supply device. A supply device having such a design is particularly advantageous. This is because the configuration of the at least one holding device advantageously enables the component belt to be cut and retracted, and furthermore, the at least one holding device makes it particularly easy to hold down the component belt when it is retracted.

[0022] According to a preferred further development of the invention, it may be provided that, with respect to the feeding device, at least one pressure device is at least partially made of spring steel and / or a non-magnetic material for holding down the components belt. As described in the previous paragraph, the at least partially elastic pressure device advantageously allows for flexible contact and holding down of the components belt as the components belt is retracted. Constructing the at least one pressure device from a non-magnetic material advantageously allows for contact, particularly an at least partially moving and / or abrasive contact, of the components belt and / or the components, without magnetizing and / or charging the at least one pressure device. This configuration of the at least one pressure device advantageously reduces and / or avoids influences on the components and ensures electrostatic compatibility of the feeding device. A feeding device constructed in this way is particularly advantageous because the configuration of the at least one pressure device advantageously allows for cutting and retraction of the components belt, and furthermore, the at least one pressure device particularly easily allows for holding down the components belt as the components belt is retracted.

[0023] According to a preferred further development of the invention, it may be provided that the supply device includes a pickup window device for supplying components to the surface mounting machine, and that at least one pressure device is arranged and / or fixed to the pickup window device. Preferably, the pickup window device is movably, particularly pivotably, attached to the supply device, and its mobility allows for convenient access to the component belt. By integrating and / or fixing the at least one pressure device to the pickup window device, particularly easy access to the component belt is possible and / or a particularly advantageous positioning of the at least one pressure device relative to the drive device is possible. The pickup window device is preferably arranged at least partially on and / or around the drive device. A supply device constructed in this way is particularly advantageous because the configuration of the at least one pressure device and the pickup window device advantageously allows for the component belt to be cut and retracted, and the at least one pressure device particularly easily allows for the component belt to be clamped during retraction.

[0024] According to a preferred further development of the invention, it may be provided that the at least one pressure device for the supply device includes at least one guide device for vertical and, in particular, lateral guidance of the component belt and / or the protective film. Pressure on the component belt during retraction is preferably enabled by permanent, temporary, and / or partial vertical guidance of the component belt by the at least one pressure device. Furthermore, the at least one pressure device preferably enables lateral guidance of the component belt and / or the protective film. Here, the references to vertical and lateral directions are preferably understood to refer to a direction in and / or along the forward movement of the component belt in the supply device. Vertical and, in particular, lateral guidance of the component belt by the at least one pressure device advantageously enables cutting and retraction of the component belt, and furthermore, the at least one pressure device makes it particularly easy to pressure the component belt during retraction.

[0025] According to a preferred further development of the invention, it may be specified that the supply device includes at least two or more pressure devices, in particular arranged in the forward direction, in particular in front of the drive device. Pressure on the components belt during retraction is particularly advantageously enabled by at least two or more pressure devices. Depending on the design of the supply device and / or the length of the section of the components belt within the supply device, it may be advantageous to provide at least two or more pressure devices for pressure on the components belt during retraction, thereby avoiding or at least reducing warping and / or unintended displacement of the components belt. A supply device with such a design is particularly advantageous because the configuration and / or arrangement of two or more pressure devices advantageously enables cutting and retraction of the components belt, and furthermore, at least one pressure device makes it particularly easy to pressure the components belt during retraction.

[0026] According to a second aspect of the present invention, this problem is solved by a component cassette having a component reel with a component belt and a supply device according to the first aspect. This component cassette offers all the advantages already described for the supply device according to the first aspect of the present invention. The component reel and / or the supply device are preferably integrated into the body of the component cassette, in particular into the housing. A component cassette with such a design is particularly advantageous due to the supply device, since it advantageously allows the component belt to be cut and retracted, and at least one pressure device makes it particularly easy to hold down the component belt when it is retracted.

[0027] According to a third aspect of the present invention, the object is achieved by a method for transporting a component belt by a feeding device, in particular by a feeding device according to the first aspect, the method comprising: - cutting the component belt by a cutting device, in particular a cutting device of the feeding device and / or of the surface mounting machine; - retracting the component belt by means of the drive of the feeding device; - pressing down the parts belt by a press-down device of the feeder device when the parts belt is retracted; Includes:

[0028] The described transport method achieves all the advantages already described with respect to the feeding device according to the first aspect of the present invention. The method steps described above and below may be performed individually, together, singly, multiple times, in parallel, and / or consecutively in any order, unless explicitly stated otherwise. For example, the references to a "first method step" and a "second method step" do not imply a chronological order and / or priority. The preferred order of the method steps assumes that the method steps are performed in the order described. The method preferably includes a step of reversing the component belt and then advancing it again, for example, by 10 mm to 50 mm, particularly about 30 mm. Reversing the component belt can be understood, for example, as loosening the component belt relative to the drive and / or film winding device. Such a transport method is particularly advantageous with a feeding device, since it advantageously allows the component belt to be cut and retracted, and the hold-down device particularly facilitates the component belt to be held down during retraction.
