Description

[0001] The invention relates to a soldering tool holder, a soldering tool, a heating element, a soldering tip, a soldering tool assembly and a handling system.

[0002] From EP0536472A1, a method for automated hand soldering using a soldering iron mounted on a robot is known, wherein the soldering iron has a heating element and a soldering tip. Due to the continuous and efficient process times in automated hand soldering, the soldering tip experiences high wear and therefore needs to be replaced regularly.

[0003] The invention is based on the objective of providing a simplified and optimized replacement of soldering tips with low assembly tolerances.

[0004] The problem underlying the invention is solved by a soldering tool holder with the features of claim 1. The invention relates to a soldering tool holder for receiving a soldering tool, the soldering tool holder comprising: a holder housing with a first housing part and a second housing part formed separately from the first housing part, wherein the second housing part is movable relative to the first housing part between an open position and a closed position. Preferably, the first housing part and the second housing part rest against each other substantially along a dividing plane in the closed position.

[0005] The soldering tool holder further comprises: a tool receptacle extending along a holder axis and formed by the first housing part and the second housing part for receiving the soldering tool, at least one contact section arranged on the tool receptacle for axially securing the soldering tool, and at least one orientation section arranged on the tool receptacle for ensuring a suitable rotational orientation of the soldering tool in relation to the holder axis.

[0006] In the open position, the tool holder is accessible, allowing a soldering tool, in particular a heating element and / or a soldering tip, to be removed from and inserted into the tool holder. In the closed position, the soldering tool is precisely fixed axially and rotationally within the tool holder. In the closed position, soldering can be performed using the soldering tool on a handling device, which can grip the soldering tool by means of the soldering tool holder.

[0007] Due to the mounting section, a soldering tool and / or a heating element and / or a soldering tip are axially fixed along the holder axis. Thus, the soldering tool holder ensures precise axial positioning of the soldering tool. The axial extent of the soldering tool is therefore determined from the mounting section, with the axial extent of the heating element and the soldering tip being relevant. Since low manufacturing tolerances are incorporated for the heating element and the soldering tip, as well as their connection, the distance between the mounting section and the free distal end of the soldering tip is known with very high accuracy. This is particularly advantageous for an automated manual soldering process.

[0008] The orientation section is designed as a poka-yoke element, ensuring that the soldering tool can only be inserted into the soldering tool holder in a suitable radial orientation. This is particularly advantageous if the soldering tip, especially the free distal end, is not rotationally symmetrical, particularly if it has a bevel. The orientation of the soldering tip is always predetermined and known thanks to the orientation section. A similar approach is also possible if the soldering tool has two, three, or four suitable orientations.

[0009] The soldering tool holder also offers the advantage that a handling device can accommodate soldering tools without the soldering tools needing to be adapted to the handling device. The soldering tool holder can, in particular, be seen as an adapter between the soldering tool and the handling device.

[0010] The tool holder is preferably formed by a recess extending along the mounting axis. In the closed position, the recess preferably comprises a first recess section provided on the first base part and a second recess section provided on the second base part. In the closed position, the tool holder is bounded with respect to the mounting axis by the first recess section and the second recess section. The tool holder is preferably corresponding to a shank section of the soldering tool and / or is at least substantially cylindrical. Both recess sections can be semi-cylindrical. Alternatively, the first recess section is semi-cylindrical and the second recess section has two clamping chamfers.

[0011] The second recess section further forms a clamping section arranged on the tool holder for radially clamping the soldering tool in the tool holder in the closed position. The second recess section, in particular the clamping section, preferably has a smaller diameter than the first recess section and / or the soldering tool in a shank area. If the second recess section is formed with chamfers, the diameter of the clamping section is determined by a circle located on the inside of the chamfers. The first recess section preferably forms a counter-clamping section in the closed position. This radially secures the soldering tool. Alternatively or additionally, the at least one contact section and / or orientation section forms the clamping or counter-clamping section.

[0012] The tool holder preferably comprises a heating element holder for receiving a heating element, in particular its heating element mount, and a soldering iron holder for receiving a soldering iron section, in particular a soldering iron. The soldering iron holder preferably has a larger diameter than the heating element holder. The heating element is preferably connected to the soldering iron section by means of a plug connection. The soldering iron section preferably comprises a power supply unit, in particular an electrical one, for supplying energy to the soldering tool and / or a control unit for controlling the soldering tool.

[0013] The at least one installation section and the at least one orientation section can be interconnected, i.e., formed together in one or more elements. Alternatively, the at least one installation section and the orientation section can be formed separately from each other and / or arranged parallel and / or tangentially to the mounting axis at a distance from each other.

[0014] Along the mounting axis, the clamping section is preferably arranged between the at least one contact section and the at least one orientation section. The same applies to the counter-clamping section if it is not formed by the contact section and / or the orientation section.

[0015] An advantageous aspect of the invention provides that the at least one contact section is designed as at least one contact groove, in particular extending perpendicular to the mounting axis and / or projecting away from a cylindrical contour of the recess. Alternatively, an advantageous aspect of the invention provides that the at least one contact section is designed as at least one contact lug, in particular extending perpendicular to the mounting axis and / or projecting away from a cylindrical contour of the recess and / or extending into the recess. This provides a particularly simple contact section for axially securing the soldering tool.

[0016] The at least one mounting section, in its form as a mounting nose, preferably has a mounting face directed radially inwards with respect to the mounting axis, a mounting surface extending perpendicular to the mounting axis, and two mounting flanks extending radially to the mounting axis. Correspondingly, the at least one mounting section, in its form as a mounting groove, preferably has a mounting base corresponding to the mounting face, a mounting surface, and two mounting flanks. In the following description, the terms mounting face and mounting base apply interchangeably to both the mounting nose and the mounting groove.

[0017] For axial securing, the mounting-side contact surface and a tool-side counter-contact surface of a counter-contact section of a soldering tool and / or a heating element and / or a soldering tip preferably come into contact. The contact surface and the counter-contact surface are preferably designed to correspond to each other. A counter-contact lug preferably engages in a contact groove and / or a contact lug preferably engages in a counter-contact groove. The counter-contact lug and / or the counter-contact groove are preferably designed corresponding to the contact lug or the contact groove, respectively.

[0018] The at least one contact section also provides a rotation lock for the soldering tool. Accordingly, preferably at least one contact flank comes into contact with at least one counter-contact flank of a counter-contact section of a soldering tool. Therefore, the soldering tool cannot be rotated relative to the soldering tool holder in the closed position.

[0019] The at least one system section and / or orientation section are preferably immovable or permanently connected to the mounting housing.

[0020] The system section and / or orientation section can also be used as a characterizing element for an image processing camera system, by means of which the relative position between a handling device, in particular a robot, and the soldering tool holder can be determined.

[0021] An advantageous aspect of the invention provides that the at least one contact section comprises at least one first contact section arranged on the first housing part and / or at least one second contact section arranged on the second housing part. In the closed position, the first contact section and the second contact section are preferably arranged opposite each other. In the closed position, the support axis runs, preferably centrally, between the first contact section and the second contact section.

[0022] The first mounting section is preferably designed as a T-shaped mounting groove with a cross-section perpendicular to the mounting axis. Accordingly, the mounting groove has a three-part mounting base, with two lateral sections having a first depth and a central section arranged between the lateral sections having a second depth. The first depth is preferably greater than the second depth. The upper part of the T-shape of the T-shaped mounting groove of the first mounting section is preferably directed towards or adjoins the tool holder or recess.

[0023] A counter-section of the soldering tool and / or the heating element and / or the soldering tip can preferably have at least two opposing counter-contact lugs, with each counter-contact flank engaging a lateral section of the T-shaped contact groove of the contact section of the soldering tool holder. This ensures reliable anti-rotation protection, particularly in conjunction with the radial clamping of the soldering tool.

[0024] The second mounting section is preferably designed as a one-piece mounting groove. If the counter-mounting section has four counter-mounting lugs, the two additional counter-mounting lugs are engaged by the central part of the T-shaped mounting groove and by the mounting groove of the second mounting section. Preferably, the counter-mounting faces of the counter-mounting lugs are spaced apart in the closed position from the central section of the T-shaped mounting groove and / or the base of the mounting groove of the second mounting section. Accordingly, the soldering tool is secured radially solely by the clamping and counter-clamping sections.

[0025] An advantageous aspect of the invention provides that the at least one orientation section is designed as at least one orientation groove, in particular extending perpendicular to the mounting axis and / or projecting away from a cylindrical contour of the recess. Alternatively, an advantageous aspect of the invention provides that the at least one orientation section is designed as at least one orientation lug, in particular extending perpendicular to the mounting axis and / or projecting away from a cylindrical contour of the recess and / or extending into the recess. This provides a particularly simple orientation section for correct rotational orientation of the soldering tool.

[0026] The at least one orientation section, in its form as an orientation nose, preferably has an orientation front facing radially inward with respect to the mounting axis, an orientation surface extending perpendicular to the mounting axis, and two orientation flanks extending radially to the mounting axis. Correspondingly, the at least one orientation section, in its form as an orientation groove, preferably has an orientation base corresponding to the orientation front, an orientation surface, and two orientation flanks. In the following description, the terms orientation front and orientation base are used interchangeably for both the orientation nose and the orientation groove.

[0027] To ensure that an operator or robot can insert the soldering tool into the soldering tool holder only in the correct rotational orientation, the holder-side orientation section engages with a tool-side counter-orientation section, or the holder-side orientation section receives a tool-side counter-orientation section. The orientation section and the counter-orientation section are preferably configured to correspond with each other. A counter-orientation lug preferably engages in an orientation groove, and / or an orientation lug preferably engages in a counter-orientation groove. The counter-orientation lug and / or the counter-orientation groove are preferably configured according to the orientation lug or the orientation groove, respectively.

[0028] An advantageous aspect of the invention provides that the at least one orientation section comprises a first orientation section arranged on the first housing part and / or a second orientation section arranged on the second housing part. The first orientation section and the second orientation section are preferably not configured to correspond to each other, with one preferably being configured as an orientation lug and the other as an orientation groove.

[0029] It is advantageous if the soldering tool is designed corresponding to the first and second orientation sections. Accordingly, the soldering tool preferably has a first counter-orientation section and a second counter-orientation section. The first counter-orientation section is preferably designed corresponding to the first orientation section. If the first orientation section is designed as an orientation lug, the first counter-orientation section is designed as a counter-orientation groove. Similarly, the second orientation section is preferably designed as an orientation groove and the second counter-orientation section as a counter-orientation lug.

[0030] In this case, preferably the first orientation section, and in particular the only one, is designed as a good orientation section and the first counter-orientation section, and preferably the second orientation section, and in particular the only one, is designed as a bad orientation section and the second counter-orientation section, and preferably the only one, is designed as a bad counter-orientation section. If several correct orientations are conceivable, then several good (counter-)orientation sections and, if necessary, several bad (counter-)orientation sections on the soldering tool and in the soldering tool holder are also conceivable.

[0031] It is advantageous if the first counter-orientation section and the second counter-orientation section are arranged around the tool axis on the soldering tool. For example, the first counter-orientation section can be at 0° and the second counter-orientation section at 180°.

[0032] This offers two advantages. Firstly, the soldering tool holder can only be closed if the soldering tool is correctly rotated within the tool holder. This is the case when the two good sections and the two bad sections are arranged in pairs, forming a groove and a lug facing each other. Even if there is only one good section on the holder side and one on the tool side, and no bad sections, the soldering tool holder could still be closed. Secondly, the bad section on the soldering tool ensures that the operator can always see where the good section is located, as it is preferably positioned opposite the bad section. Consequently, the good section can be concealed, and the operator can still reliably insert the soldering tool into the soldering tool holder in the correct rotation.

[0033] It is advantageous if the first and second orientation sections also function as radial clamping and counter-clamping sections. In this case, the second housing part presses the counter-orientation section against the first orientation section.

[0034] The soldering tool holder is preferably designed such that if a soldering tool is inserted into the tool holder in an incorrect rotational orientation, the second housing part cannot be moved from the open position to the closed position.

[0035] One embodiment comprises a first orientation section with an orientation lug and a counter-orientation groove. The orientation lug is preferably arranged in the tool holder, wherein, in the region of the orientation lug, the tool holder on the first housing part is preferably rectangular, and in particular semi-square, in cross-section perpendicular to the mounting axis. The substantially cylindrical soldering tool has the counter-orientation groove, wherein the cylindrical outer contour of the soldering tool, in particular the shank section, is flattened at a distance of ±90° from the counter-orientation groove. The flattened area of ​​the soldering tool, in particular the shank section, is guided by two flanks of the rectangular inner contour of the tool holder. Thus, correct rotational orientation is ensured when inserting the soldering tool into the soldering tool holder.A counter-orientation lug is preferably arranged on the soldering tool opposite the counter-orientation groove. This prevents the soldering tool from being used if it is rotated 180° for correct orientation, as the lugs would then meet. If this orientation does occur, the second housing part cannot be moved into the closed position. Therefore, the first and second housing parts are preferably designed such that the two overlapping lugs create a stop. This stop is designed to prevent the connecting sections of the two housing parts from interacting and / or interlocking. A groove in the second housing part is preferably provided to accommodate the counter-orientation lug. Alternatively, the second recess section can have a larger diameter in the area of ​​the orientation section to accommodate the counter-orientation lug.In this case, in the closed position, the counter-orientation nose preferably comes into contact with the cylindrical inner contour of the second recess section.

[0036] An advantageous aspect of the invention provides that the first housing part has at least one first connecting section and the second housing part has at least one second connecting section which, in the closed position, interacts with the first connecting section and extends, in particular, perpendicular to the mounting axis. The second connecting section can be designed as a connecting pin and the first connecting section as a pin receptacle with a ball detent. The ball detent is preferably arranged perpendicular to the connecting pin. The ball detent clamps the connecting pin in the pin receptacle. Preferably, the connecting pin has a chamfer and the pin receptacle has a corresponding chamfer, which are clamped by the ball detent. Additionally or alternatively, the connecting pin has a connecting groove into which the ball detent engages in an undercutting manner.The connection is designed so that the two housing parts are held securely, yet can be easily released by an operator.

[0037] Preferably, the connecting pin is arranged perpendicular to the separating axis on a first pin side facing the mounting axis. Preferably, the connecting pin is arranged at an angle to the separating axis on a second pin side facing away from the mounting axis. Thus, the connecting pin tapers towards its free end. This ensures particularly easy insertion of the connecting pin into the pin receptacle when pivoting the second housing part from the open position to the closed position.

[0038] Furthermore, additional connecting means may be provided. A further connecting means is preferably a connecting screw arranged on the first or second housing part, which can be connected, in particular screwed, to a threaded bore interacting with the second or first housing part. Accordingly, the simple connection can be further secured easily by means of the connecting pin-ball-pressure bolt pair.

[0039] An advantageous aspect of the invention provides that the first housing part and the second housing part are connected by means of a hinge extending along a hinge axis. The second housing part is preferably pivotable relative to the first housing part between the open and closed positions about the hinge axis. The hinge axis preferably runs parallel to the mounting axis. The hinge axis and the mounting axis preferably lie in the dividing plane of the housing parts. The hinge means ensures that the housing parts remain connected and can be easily opened and closed.

[0040] An advantageous aspect of the invention provides that the mounting housing has a robot interface on one side of the housing shell for connection to a handling device. The robot interface can preferably have several interface pins which can be picked up or gripped by a handling device, in particular a gripper on the handling device.

[0041] The problem underlying the invention is also solved by a soldering tool with the features of claim 10. The invention relates to a soldering tool for manual and / or automated hand soldering of components, wherein the soldering tool extends along a tool axis and comprises: a soldering tip for hand soldering the components, a heating element arranged in or on the soldering tip for heating the soldering tip, at least one counter-contact section for axially securing the soldering tool to a soldering tool holder and / or handling device, at least one counter-orientation section for ensuring a suitable rotational orientation of the soldering tool with respect to the tool axis on a soldering tool holder and / or handling device.

[0042] The soldering tool preferably has one, several or all of the features of the counter-position and / or counter-orientation sections described above.

[0043] The at least one counter-position section and the at least one counter-orientation section can be interconnected, i.e., formed together in one or more elements. Alternatively, the at least one counter-position section and the counter-orientation section can be formed separately from each other and / or arranged parallel and / or tangentially to the tool axis at a distance from each other.

[0044] The soldering tool preferably has a shaft section which interacts with a clamping section of a soldering tool holder in the closed position of the soldering tool holder. Along the tool axis, the shaft section is preferably arranged between the at least one counter-contact section and the at least one counter-orientation section.

[0045] An advantageous aspect of the invention provides that the at least one counter-contact section is designed as at least one counter-contact groove, in particular extending perpendicular to the tool axis and / or projecting relative to a cylindrical outer contour. Alternatively, an advantageous aspect of the invention provides that the at least one counter-contact section is designed as at least one counter-contact lug, in particular extending perpendicular to the tool axis and / or projecting relative to a cylindrical outer contour. The cylindrical outer contour of the soldering tool is preferably formed by a shaft section of the soldering tip and / or the heating element and / or the heating element holder.

[0046] An advantageous aspect of the invention provides that the at least one counter-orientation section is designed as at least one counter-orientation groove, in particular extending perpendicular to the tool axis and / or projecting relative to the cylindrical outer contour. Alternatively, an advantageous aspect of the invention provides that the counter-orientation section is designed as at least one counter-orientation nose, in particular extending perpendicular to the tool axis and / or projecting relative to the cylindrical outer contour.

[0047] An advantageous aspect of the invention provides that the at least one counter-orientation section comprises a, in particular a single, good counter-orientation section and a, in particular a single and / or opposite, bad counter-orientation section. The good counter-orientation section and the bad counter-orientation section are preferably configured differently, in particular correspondingly, to each other.

[0048] An advantageous aspect of the invention provides that the soldering tip and the heating element are detachable from one another, in particular by means of a bayonet fitting. Since the soldering tip typically wears out or fails faster than the heating element, the soldering tip can be replaced and the heating element reused. Such a detachable fitting is known from DE102020130464A1, in particular in paragraphs

[0047] and

[0048] . Accordingly, preferably, locking sections, in particular locking lugs, are provided on the heating element, and a locking knurl or a heating element interface with locking receptacles for receiving the locking lugs is provided on the soldering tip. Undercuts are provided on the locking receptacles, which engage behind the locking sections in the assembled state and thus provide a detachable, positive-locking connection between the heating element and the soldering tip.Alternatively, the soldering tip and heating element are permanently connected. In this case, if the soldering tip fails, the heating element must also be replaced. The bayonet fitting also has the advantage that only a quarter or half turn is required to connect and disconnect it.

[0049] It is advantageous if the Poka-Yoke principle is also used at the locking knurl, the heating element interface, and the soldering tip holder. Preferably, the heating element interface has several locking receptacles, particularly those evenly distributed around the tool axis. Preferably, the soldering tip holder has several locking lugs, particularly those evenly distributed around the tool axis. In the assembled state, a locking lug is arranged in a locking receptacle. To ensure correct rotational orientation between the soldering tip and the heating element with respect to the tool axis, a locking lug and a locking receptacle are wider tangentially, i.e., along the circumference around the tool axis.The larger locking section, in particular the larger locking lug, is preferably designed such that it can only be inserted into the larger locking receptacle and not into the remaining locking lugs. This ensures that the soldering tip can only be mounted on the heating element in the correct rotational orientation by the operator. To facilitate the operator's better visibility and / or identification of the larger locking section and / or the larger locking receptacle, a characteristic feature, such as a bump, line, notch, arrow, etc., can be provided on the outer surface of the soldering tip and / or the heating element.

[0050] The problem underlying the invention is also solved by a heating element with the features of claim 15. The invention relates to a heating element of a soldering tool, comprising: a soldering tip holder for the releasable reception of a soldering tip, at least one counter-position section for axially securing the heating element to or in a soldering tool holder or to or in a handling device, and at least one counter-orientation section for ensuring a suitable rotational orientation of the heating element with respect to the holder axis to or in a soldering tool holder or to or in a handling device.

[0051] An advantageous aspect of the invention provides that the heating element further comprises: a heatable heating section or a heatable stem tube, a heating element holder receiving and surrounding the heating section, wherein the at least one counter-positioning section and / or the at least one counter-orientation section is arranged on the heating element holder and / or the soldering tip receptacle, in particular the at least one closure section for the releasable connection with the soldering tip.

[0052] The problem underlying the invention is also solved by a soldering tip with the features of claim 17. The invention relates to a soldering tip of a soldering tool, comprising: a heating element interface for connection with a heating element, at least one counter-position section for axially securing the soldering tip to or in a soldering tool holder or to or in a handling device, at least one counter-orientation section for ensuring a suitable rotational orientation of the soldering tip to or in a soldering tool holder or to a handling device with respect to the holder axis.

[0053] It is advantageous if the heating element interface of the soldering tip is designed as a knurled section. The knurled section has a cylindrical outer contour with a plurality of grooves distributed around the tool axis, the grooves running parallel to the tool axis. The knurled section also has a cover element located on the side of the grooves facing the free end of the soldering tip. The cover element projects radially from the grooves. In addition to or as an alternative to the grooves, at least two opposing and / or parallel-extending grooves are provided in the outer contour. The grooves preferably have a larger cross-section than the grooves. The grooves preferably extend through the cover element. The knurled section can be gripped by means of a handling device via the grooves, thus enabling automatic changing of the soldering tip on the heating element and / or the soldering tool holder.

[0054] An advantageous aspect of the invention provides that the soldering tip further comprises: a tip section, a soldering tip holder receiving and surrounding the tip section, wherein the at least one counter-positioning section and / or the at least one counter-orientation section and / or the heating element interface, in particular the locking knurl for the releasable connection with the heating element, is arranged on the soldering tip holder.

[0055] The problem underlying the invention is also solved by a soldering tool assembly with the features of claim 19. The invention relates to a soldering tool assembly with a soldering tool holder as described above. The soldering tool assembly further comprises a soldering tool as described above and / or a heating element as described above and / or a soldering tip as described above and received in the soldering tool holder.

[0056] An advantageous aspect of the invention provides that in the closed position, the at least one attachment section interacts with the at least one counter-attachment section and / or the at least one orientation section interacts with the at least one counter-orientation section.

[0057] The soldering tool assembly is preferably designed such that the orientation section and the counter-orientation section ensure a fundamentally correct radial orientation range with a deviation between -10° and +10°, in particular -5° and +5°. The subsequent orientation then takes place when the second housing part is moved into the closed position, whereby the clamping section radially clamps the soldering tool against the counter-clamping section. The soldering tool is thereby fully and precisely aligned by means of the at least one counter-stop section and / or the at least one counter-orientation section and / or the flattened flanks of the cylindrical outer contour.

[0058] Reference is also made to the explanations and advantages regarding the soldering tool holder, which apply equally to the soldering tool assembly.

[0059] The problem underlying the invention is also solved by a handling system with the features of claim 21. The invention is directed to a handling system comprising a handling device with a soldering holder for receiving a previously described soldering tool holder and / or a previously described soldering tool and / or a previously described heating element and / or a previously described soldering tip, and a previously described soldering tool holder and / or a previously described soldering tool and / or a previously described heating element and / or a previously described soldering tip arranged on the soldering holder.

[0060] The problem underlying the invention is also solved by a heating element holder with the features of claim 22. The invention is directed to a heating element holder for receiving a heating section, the heating element holder comprising: at least one counter-positioning section for axially securing the heating section in a soldering tool holder, and at least one counter-orientation section for ensuring a suitable rotational orientation of the heating section in the soldering tool holder with respect to a tool axis, and at least one soldering tip receptacle for receiving a soldering tip with at least one closure section.

[0061] It is advantageous if the at least one locking section comprises a single larger locking section and at least one smaller, preferably three, locking sections to ensure a suitable rotational orientation of a soldering tip on the heating element holder with respect to the tool axis. The single larger locking section can only be inserted into a larger locking receptacle of a soldering tip. This ensures that the operator always mounts the soldering tip and the heating element, in particular the heating element holder, correctly with regard to rotational orientation.

[0062] The heating element holder can be flexibly pressed onto the heating section within its inner diameter. This allows for the compensation of manufacturing and component tolerances and ensures that the end face of the heating section always maintains precisely the same distance from the heating element holder. This also ensures that the free end of the soldering tip is axially aligned with the soldering tool holder. This is particularly advantageous because it guarantees high accuracy from the robot interface to the operating point or the free end of the soldering tip. This precise length tolerance between the contact surface of the contact section and the free end of the soldering tip ensures high manufacturing accuracy.

[0063] The heating element holder may also include one, several, or all of the features described above.

[0064] The problem underlying the invention is also solved by a heating element holder for receiving a heating section, wherein the heating element holder comprises: at least one counter-positioning section for axially securing the heating section in a soldering tool holder, and at least one soldering tip receptacle for receiving a soldering tip with at least one locking section, wherein the at least one locking section comprises a single larger locking section and at least one smaller, preferably three, locking sections for ensuring a suitable rotational orientation of a soldering tip on the heating element holder with respect to the tool axis.

[0065] Further advantages, features, and details will become apparent from the following description, in which various embodiments of the invention are illustrated with reference to the drawing. The features mentioned in the claims and the description can each be essential to the invention individually or in any combination.

[0066] They show: Fig. 1-7 a soldering tool assembly with a soldering tool and a soldering tool holder; Fig. 8-10 a first housing part of a mounting housing of the soldering tool holder; Fig. 11-13 a first housing part of a mounting housing of the soldering tool holder; Fig. 14-14A a heating element interface of a soldering tip; Fig. 15-17 a heating element holder of a heating element.

[0067] The soldering tool assembly 10 comprises a soldering tool 12 and a soldering tool holder 14 for receiving the soldering tool 12. The soldering tool 12 has a soldering tip 16, a heating element 18, and a soldering iron connection 20. The soldering tool holder 14 is designed to connect the soldering tool 12 to a handling device (not shown), in particular a robot arm and / or gripper, via a robot interface 22. Thus, the soldering tool 12 can be automated for a manual soldering process.

[0068] To allow the soldering tip 16 to be replaced without replacing the heating element 18, the soldering tip 16 and the heating element 18 are detachably connected. For this purpose, a connection between the soldering tip 16 and the heating element 18 known from DE102020130464A1 is provided. The soldering tip 16 has a heating element interface 24, in particular a knurled section, for connection to a soldering tip receptacle 26 of the heating element 18. The knurled section has, according to Fig. 14 has a cylindrical outer contour with grooves 30 extending along a tool axis 28 for manual opening and slots 32 for automated opening. Furthermore, a cover element 34 is provided facing the free end of the soldering tip 16 or the tip section of the soldering tip 16, wherein the grooves 30 are axially closed off by the cover element 34 and the slots 32 extend through the cover element 34. The heating element interface 24 has locking receptacles 36 for receiving locking sections 38, in particular locking lugs, arranged on the soldering tip receptacle 26, wherein the locking sections 38 preferably engage behind undercuts formed by the locking receptacle 36.

[0069] The detachable connection is preferably designed as a bayonet fitting.

[0070] It is advantageous if the Poka-Yoke principle is also used at the heating element interface 24 and the soldering tip holder 26. Preferably, the heating element interface 24 has four locking receptacles 36, which are particularly evenly distributed around the tool axis 28. Preferably, the soldering tip holder 26 has four locking lugs, which are particularly evenly distributed around the tool axis 28. In the assembled state, one locking lug is arranged in a locking receptacle 36. To ensure correct rotational orientation between the soldering tip 16 and the heating element 18 with respect to the tool axis 28, one locking lug and one locking receptacle 36 are wider tangentially, i.e., along the circumference around the tool axis 28.The larger closure section 38A, in particular the larger closure nose, is preferably designed such that the larger closure section 38A, in particular the larger closure nose, can only be inserted into the larger closure receptacle 36A and cannot be inserted into the remaining closure noses.

[0071] The heating element 18 preferably has a rod-shaped heating section 39 and a heating element holder 40 that accommodates the heating section 39.

The tool receptacle 44 has a heating element receptacle 48 for receiving the heating element 18, in particular the heating element holder 40, and a soldering iron receptacle 50 for receiving the soldering iron connection 20. The soldering iron receptacle 50 has a larger diameter than the heating element receptacle 48.

[0073] The mounting housing 42 comprises a first housing part 52 and a second housing part 54 formed separately from it. The second housing part 54 is positioned relative to the first housing part 52 between an open position, in which the soldering tool 12 can be inserted or removed, and a closed position, in which the soldering tool 12 is locked and cannot be inserted or removed. The first housing part 52 and the second housing part 54 are connected by means of a hinge element 58 extending along a hinge axis 56 and are pivotable relative to each other about the hinge axis 56. In the closed position, the first housing part 52 and the second housing part 54 are in contact with each other substantially along a parting plane 60. The mounting axis 46 and the hinge axis 56 preferably lie in the parting plane 60.

[0074] The first housing part 52 has a first recess section 62 and the second housing part 54 has a second recess section 64. The first recess section 62 and / or the second recess section 64 are essentially semi-cylindrical and, in the closed position, form an essentially cylindrical tool receptacle 44.

[0075] The robot interface 22 is preferably arranged on a side 66 of the first housing part 52.

The contact groove has a contact surface 70 extending perpendicular to the holder axis 46. The contact groove is designed according to Fig. 4 and Fig. The system is T-shaped. The groove has a three-part base 74 with two lateral base sections 74A and a central base section 74B, wherein the central base section 74B preferably has a greater depth than the depth of the lateral base sections 74A. The depth of the lateral base sections 74A is preferably identical.

[0078] According to Fig. 11 and Fig. 12 The soldering tool holder 14 has a second mounting section 68B in the form of a mounting groove arranged in the second housing part 54. The mounting groove has according to Fig. 4 and Fig. 6 a continuous base 74 on.

[0079] According to Fig. 15, Fig. 16 to Fig. 17 The heating element 18, in particular the heating element holder 40, has at least one counter-contact section 72 comprising four counter-contact lugs distributed around the tool axis 28. Each counter-contact lug has, in relation to the tool axis 28, a counter-contact face 76A extending radially outwards and parallel to the tool axis 28, a counter-contact surface 76B extending perpendicular to the tool axis 28, and two counter-contact flanks 76C extending perpendicular to the counter-contact face 76A and the counter-contact surface 76B. Preferably, the counter-contact face 76A has a convex curvature, i.e., projecting radially outwards.

[0080] To ensure that the soldering tool 12 can be mounted precisely axially in the soldering tool holder 14, the contact surface 70 and the counter-contact surface 76B come into contact when mounted. Preferably, the holder axis 46 and the tool axis 28 are coaxially configured when mounted. This provides a positive-locking axial fixation.

[0081] Additionally, the soldering tool holder 14 has an anti-rotation device for the soldering tool 12. Furthermore, two counter-contact flanks 76C are located on the lateral base sections 74A of the first support section 68A. This prevents the soldering tool 12 from rotating about the tool axis 28 when mounted and in the closed position.

[0082] To ensure that the soldering tool 12 can only be inserted into the open holder housing 42 by an operator in the correct radial orientation, the Poka-Yoke principle is applied to both the holder housing 42 and the soldering tool 12. The soldering tool 12 has only one correct radial orientation, which is determined with respect to the holder axis 46 and the tool axis 28, respectively.

[0083] For this purpose, the mounting housing 42 has an orientation section 78A and the soldering tool 12 has a counter-orientation section 80B that interacts with the orientation section 78.

[0084] According to Fig. 9 and Fig. 10 The soldering tool holder 14 has a first orientation section 78A in the form of an orientation lug arranged in the first housing part 52. The orientation lug extends parallel to the holder axis 46. The orientation lug is preferably arranged in a receiving recess 82 of the tool holder 44, in particular the heating element holder 48. The receiving recess 82 is designed according to Fig. 9 rectangular in shape. At the receiving recess 82, the tool holder 44 deviates from the cylindrical contour. In the assembled state, the soldering tool 12 is shaped according to Fig. 5 at least partially arranged in the receiving depression 82.

[0085] Furthermore, the soldering tool holder 14 has a second orientation section 78B in the form of an orientation groove arranged in the second housing part 54. The orientation groove has, according to Fig. 12 a continuous base 74 on.

[0086] The heating element 18, in particular the heating element holder 40, exhibits according to Fig. Figure 15 comprises a first counter-orientation section 80A and a second counter-orientation section 80B. The first counter-orientation section 80A is designed as a counter-orientation groove extending along the tool axis 28. Opposite the counter-orientation groove, the second counter-orientation section 80B is designed in the form of a counter-orientation lug. In the area of ​​the counter-orientation section 80, a fastening groove is provided, extending in sections around the circumference of the heating element holder 40. In the assembled state, the heating element 39 engages in this fastening groove for axial fixation in the heating element holder 40. The fastening groove preferably divides the second counter-orientation section 80B into two spaced-apart elements.

[0087] The first orientation section 78A, or orientation lug, and the first counter-orientation section 80A, or counter-orientation groove, form a good orientation section 80 and a good counter-orientation section 80A. The second orientation section 78B, or orientation groove, and the second counter-orientation section 80B, or counter-orientation lug, form a bad orientation section and a bad counter-orientation section. Therefore, the soldering tool 12 can only be inserted into the tool holder 44 in one rotational orientation, with the lug engaging in the groove in each case.

[0088] Should the soldering tool 12 be inserted incorrectly, i.e., with the groove aligning against the groove and the tab against the tab, the mounting housing 42 is designed such that it cannot be fully moved into the closed position and therefore cannot be connected or closed. The heights of the tabs and the length of the connecting sections of the housing parts are coordinated to prevent this.

[0089] The first housing part 52 has at least one first connecting section 84, and the second housing part 54 has at least one second connecting section 86 that interacts with the first connecting section 84 in the closed position and extends, in particular, perpendicular to the mounting axis 46. The second connecting section 86 can be configured as a connecting pin 86A, and the first connecting section 84 as a pin receptacle 84B with two opposing ball detent pins 84A. The ball detent pins 84A are preferably arranged perpendicular to the connecting pin 86A. The ball detent pins 84A clamp the connecting pin 86A in the pin receptacle 84B. The connecting pin 86A has two connecting grooves 86A opposite each other, parallel to the mounting axis 46, into which a ball detent pin 84A engages in an undercutting manner. The connection is designed such that the two housing parts 52, 54 are securely held and yet easily detachable by an operator.

[0090] Preferably, the connecting pin 86A is arranged perpendicular to the separating axis on a first pin side facing the mounting axis 46. Preferably, the connecting pin 86A is arranged obliquely to the separating axis on a second pin side facing away from the mounting axis 46. Thus, the connecting pin 86A tapers towards its free end. This ensures particularly easy insertion of the connecting pin 86A into the pin receptacle 84B when pivoting the second housing part 54 from the open position to the closed position.

[0091] Preferably, at least one further connecting element 87 is provided on the housing parts 52, 54. The further connecting element 79 is preferably a screw extending perpendicular to the separating axis 60 in the closed position and a threaded bore connected to the screw.

[0092] For radially clamping the soldering tool 12 in the tool holder 44, a clamping section 88 is provided on the second housing part 54. The clamping section 88 is preferably formed by the inner contour of the second recess section 64. The second recess section 64 has two inclined surfaces in certain sections, particularly between the second contact section 68B and the second orientation section 78B, which have a smaller diameter than the soldering tool 12 and the first recess section 62. Thus, in the closed position, the soldering tool 12 is radially clamped by means of the clamping section 88 against a shaft section 90 of the soldering tool 12, arranged in particular between the counter-contact section 72 and the counter-orientation section 80, and / or a cylindrical shaft section 90 of the soldering tool 12 against the first housing part 52, in particular a counter-clamping section 89 arranged between the first contact section 68A and the first orientation section 78A.Furthermore, the lateral bottom sections 74A and / or the receiving recess 82 and / or the orientation nose can additionally or alternatively act as a counter-clamping section.
