Description

[0001] The invention relates to a stand for a soldering system and to a soldering system comprising an electric soldering device, in particular a soldering iron, and a stand. The soldering device has a handle with a heating element and a soldering tip assembly with a retaining element, which can be detachably attached to the handle. The soldering tip assembly is attached to the handle by means of a bayonet-like connection such that the handle can be moved from a fixed position to a removal position by rotating the handle relative to the retaining element and can be removed from the removal position in a proximal direction from the soldering tip assembly.

[0002] One such soldering device is, for example, the i-TOOL HIGH POWER high-performance soldering iron (article no.: 0240CDJ) of the applicant. It is known to provide a stand for holding the soldering device, in which the soldering device can be placed.

[0003] The soldering iron can be held and guided by a person using the handle. The heating element heats the soldering tip to melt the solder. Different soldering tips with different geometric shapes are required depending on the task. Therefore, the soldering tips are detachably attached to the handle. Common types of attachment include screw connections, bayonet connections, and snap-in systems.

[0004] Further electrical soldering devices are known from WO 2017 / 194261A1, DE 20 2012 008 255 U1 or DE 10 2018 102 792 B3.

[0005] The present invention is based on the objective of providing a storage stand and an associated soldering system in which the soldering tip assembly can be easily replaced.

[0006] This problem is solved by a storage stand with the features of claim 1. Consequently, it is provided that the storage stand has at least one interchangeable holder formed around an insertion axis, which is designed at least partially complementary to the retaining element such that a soldering tip assembly arranged on the handle can be inserted into and removed from the interchangeable holder along the insertion axis, and that the interchangeable holder has a rotation-locking element cooperating with the retaining element such that, when the soldering tip assembly is inserted into the interchangeable holder, the retaining element is rotationally locked in the interchangeable holder when the handle is rotated from the mounting position to the removal position.

[0007] The storage stand is therefore designed for the permanent storage of at least one soldering tip assembly, preferably several, particularly differently designed, soldering tip assemblies. Preferably, the storage stand also includes a holder for the soldering iron. The design of the storage stand is such that the hot soldering tip assembly, located at the handle, can be inserted into the holder and the bayonet-like connection released. This release of the bayonet-like connection occurs without the operator having to touch the soldering tip assembly, and especially its retaining element, with their fingers. This protects the operator from burns. Furthermore, the operator does not require any tools to change the soldering tip.

[0008] The stand can be a separate unit next to an electronics station that supplies the soldering iron with electrical power. However, it is also conceivable that the stand is formed by or integrated into such an electronics station.

[0009] To provide the anti-rotation feature, it is advantageous if the anti-rotation element has a raised and / or recessed structure that interacts with a counter-structure provided on the holding element.

[0010] In this context, the retaining element can have parallel knurling on its surface, with the anti-rotation element then being designed as at least one rib running parallel to the knurling. Preferably, the anti-rotation element comprises several such ribs that interact with the parallel knurling, and in particular with knurled ribs formed by the parallel knurling. Due to the conical design, when the soldering tip assembly is inserted into the tool holder, it is ensured that the ribs on the tool holder side engage with the parallel knurling to achieve a rotationally secure arrangement of the retaining element, and thus of the soldering tip assembly in the tool holder.

[0011] The tool holder is preferably funnel-shaped and tapered, meaning it narrows distally. Distal means facing away from the operator, and proximal means facing towards the operator. Preferably, the retaining element can also be correspondingly conical, so that the tool holder ultimately has a surface that is conical in shape complementary to the retaining element. This ensures secure insertion of the retaining element into the tool holder. Because the tool holder has an anti-rotation feature, the handle can be rotated around its longitudinal axis relative to the soldering tip assembly, which is secured within the tool holder, from the mounting position to the removal position to release the soldering tip assembly.

[0012] It has been observed that the soldering tip assembly can adhere to the heating element after use of the soldering iron. To prevent the soldering tip assembly from being removed along with the handle in a proximal direction, it is advantageously provided that a retaining element is incorporated into or attached to the tip holder. The tip holder is designed such that the soldering tip assembly can be inserted into and removed from the holder along the insertion axis in an insertion position. Furthermore, a soldering tip assembly within the tip holder can be pivoted from the insertion position to a removal position, in which the retaining element engages beneath the retaining element. This under-engagement causes the soldering tip assembly to be pulled away from the heating element when the handle is removed proximally, and it remains in the tip holder.

[0013] Furthermore, it is advantageous if the tool holder has an insertion opening on its proximal side and a bottom opening on its distal side. It is advantageous if the at least one tool holder is funnel-shaped in such a way that the funnel shape defines both the insertion and removal positions. The insertion opening can be elongated or oval, in particular, so that a soldering tip assembly located in the tool holder can be pivoted from the insertion position to the removal position. The bottom opening, on the other hand, can be circular.

[0014] The retaining element can be positioned at or near the insertion opening such that, when the soldering tip assembly is pivoted into the removal position, it engages behind the retaining element. This engagement is such that the retaining element is securely held in the tool holder when the handle is pulled off in a proximal direction in the removal position. The retaining element can, in particular, be designed as a projection extending radially towards the insertion axis.

[0015] Furthermore, it is advantageous if an insertion stop for axially positioning the retaining element is provided in or on the tool holder. Consequently, if the retaining element is inserted distally into the tool holder, a defined insertion depth of the retaining element into the tool holder can be specified by providing the insertion stop. This prevents the retaining element from jamming in the tool holder, which usually occurs when two conical parts are inserted into each other without a depth stop. It is advantageous if the insertion stop is located at or near the base opening. The insertion stop can be designed as a projection extending radially towards the insertion axis.

[0016] Furthermore, it is advantageous if at least one tool holder has a lateral opening for the lateral insertion of a soldering tip assembly. The design is preferably such that a soldering tip, whose free end has a diameter larger than the bottom opening, can be inserted laterally into the tool holder.

[0017] The stand can feature a central area with a soldering iron holder and several interchangeable holders to the side of the holder. This results in a convenient and organized arrangement. Furthermore, the stand can include additional functional sections, such as storage compartments for accessories.

[0018] It is advantageous if the storage stand is designed in one, two, or more parts and has at least one storage compartment, particularly for accessories, a change holder, a shelf for soldering tips, and a soldering iron holder, wherein the at least one storage compartment and / or the shelf is arranged facing the user. This allows, for example, two different cleaning agents, such as a sponge and wool, to be used simultaneously and be accessible to the user.

[0019] Furthermore, it is conceivable that a reading device for reading a code provided on the soldering tip assembly is provided in or on the storage stand. The code can be provided, in particular, on the holding element as an optically readable code for identifying the soldering tip assembly.

[0020] The coding is primarily two-dimensional, for example, in the form of a barcode or QR code. It can also be in the form of an RFID code. The coding can be applied, for example, to a radially recessed surface of the retaining element and printed using pad printing. Two-dimensional coding is particularly advantageous when the retaining element is made of plastic, as the plastic does not change color even at higher temperatures. Pad printing can be carried out using white ink to optimize the contrast with the plastic, which is preferably black or dark gray.

[0021] The advantage of such coding is that it allows for tracking which soldering tip is being used. For example, the reader could be mounted on a stand where the soldering tips can be stored. After picking up a soldering tip, it can be passed by the reader, thus recording which tip is being used. Furthermore, it's conceivable that after selecting a suitable soldering tip, it can be verified that the chosen tip is indeed the desired one. Alternatively, the reader could be a separate unit or integrated into an electronics station that supplies the soldering equipment with power.

[0022] By recessing the coding on the radially offset surface, the code is permanently protected from abrasion and other environmental influences. This ensures the code remains legible over time. Each soldering tip assembly type is assigned a unique code, guaranteeing unambiguous identification. The information captured by the reader can be further processed using software. The data can be structured and displayed in a user-friendly format. It is also conceivable that the data can be processed automatically using database software or a Manufacturing Execution System (MES), particularly for process monitoring.

[0023] This allows a specific soldering tip to be assigned to a specific soldering task, making this known to the user and also allowing it to be verified.

[0024] The aforementioned problem is also solved by a soldering system comprising a soldering device, an electronic station for supplying the soldering device with electrical energy and a storage stand according to the invention.

[0025] For the arrangement of the handle on the soldering tip assembly, it is advantageous if the holding element has recesses on its proximal side and, between the recesses, rear grip sections which provide contact sections on their distal side, and if the handle has counter-sections between the heating element and a proximal hand section for contact with the contact sections. The counter-sections can then be inserted into the recesses and bayoneted in place by rotating the handle relative to the holding element.

[0026] Furthermore, it is advantageous if the soldering tip assembly comprises a sleeve extending around a longitudinal axis, a soldering tip provided at the distal end of the sleeve and the retaining element, wherein a spring element is provided between the retaining element and the sleeve, which pushes the retaining element in a distal direction.

[0027] Further details and advantageous embodiments of the invention can be found in the following description, which provides a more detailed description and explanation of an exemplary embodiment of the invention.

[0028] They show: Fig. 1 a soldering device with a handle and a soldering tip assembly mounted on it; Fig. 2 the soldering tip assembly according to Fig. 1 in representation detached from the handle; Fig. 3 an enlarged view of section III in Fig. 2; Fig. 4 the soldering tip assembly according to Fig. 2 in a view from a rear oblique angle; Fig. 5 a longitudinal section through the soldering tip assembly according to Fig. 4; Fig. 6 A view of the retaining element of the soldering tip assembly from a rear oblique angle; Fig. 7 A view of the retaining element of the soldering tip assembly from a front oblique angle; Fig. 8 a section through a soldering tip assembly arranged on the handle; Fig. 9 a storage stand for a soldering tip assembly; and Fig. 10 a cut through the storage stand according to Fig. 9 with a soldering tip assembly.

[0029] In the Fig. Figure 1 shows a soldering device 10 in the form of a soldering iron, comprising a handle 12 and a soldering tip assembly 14. The handle 12 includes a hand section 16 at its proximal end, which can be gripped by a user. The handle 12 further comprises, as shown in Figure 1, a soldering iron in the form of a soldering iron. The handle 12 also includes a hand section 16, which can be gripped by a user. Fig. As can be clearly seen in Figure 2, a rod-shaped heating element 18 with a free end 19 is located at its distal end, and the replaceable soldering tip assembly 14 is ultimately heated by the heating element 18. On the side of the hand section 16 facing away from the heating element 18, as shown in Figure 2, a rod-shaped heating element 18 is located at its distal end. Fig. As is clearly shown, a connecting cable 20 is provided, with which the soldering device 10 can be supplied with power.

[0030] The soldering tip assembly 14 shows, as can be seen from the Fig. 2, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. As can be clearly seen in Figure 8, a sleeve 22 is shown, at the distal end of which a soldering tip 24 is attached. The sleeve 22 may have window-like recesses 21. In the embodiment shown in the figures, the soldering tip 24 is formed as a separate part from the sleeve 22; however, it is also conceivable that the soldering tip 24 is formed in one piece and / or integrally with the sleeve 22.

[0031] The soldering tip assembly 14 further comprises a retaining element 26 arranged around a longitudinal axis 23, which surrounds the sleeve 22 at least partially in a ring-like manner and is conically tapered towards the soldering tip 24. The retaining element 26 has parallel knurling on its surface formed by knurled ridges 27. The retaining element 26 serves to place the soldering tip assembly 14 onto the handle 12 and to remove it from the handle 12. While the soldering tip 24 and the sleeve 22 are made of a metallic material, the retaining element 26 is preferably made of a suitable plastic.

[0032] As can be seen from the enlarged section according to Fig. As can be clearly seen in Figure 3, the handle 12 has rib-like counter-sections 28 in the area between the heating element 18 and the hand section 16. A total of four counter-sections 28 are provided, arranged opposite each other. Each counter-section 28 has axially extending locking lugs 30 on its proximal side.

[0033] As from the Fig. 4 and Fig. As can be clearly seen in Figure 5, which shows the soldering tip assembly 14 with the soldering tip 24 deflected distally, the retaining element 26 has four recesses 32 on its proximal side into which the opposing sections 28 can be inserted axially. Between each pair of recesses 32, a rear gripping section 34 projecting radially inwards is provided. The rear gripping sections 34 have contact sections 36 on their distal side, which serve to receive the opposing sections 28 or their locking lugs 30. The contact sections 36 are designed to be complementary to the locking lugs 30, so that these can come into defined and secure contact in the contact sections 36.

[0034] From the section according to Fig. Figure 5 shows that the soldering tip assembly 14 comprises, in addition to the soldering tip 24, the sleeve 22, and the retaining element 26, a spring element 38. The spring element 38 is positioned between the sleeve 22 and the retaining element 26 such that it pushes the retaining element 26 away from the hand section 16 in a distal direction. The spring element 38 is designed as a helical spring and surrounds the sleeve 22. At the proximal end of the sleeve 22, the sleeve has an opening 60 and a radially projecting flange section 40, against which the spring element 38 acts. Opposite the flange section 40, the retaining element 26 has a proximal inner surface 42 facing the flange section 40, which surrounds the sleeve 22 and against which the spring element 38 also acts. The spring element 38 is arranged and pre-tensioned in such a way that, as already described, it pushes the retaining element 26 on the sleeve 22 in a distal direction.

[0035] To secure the retaining element 26, which is in particular a single piece and made of plastic, to the sleeve 22 in a loss-proof manner, the sleeve has stop means 44 which prevent the sleeve 22, together with the soldering tip 24, from being pulled off the retaining element 26 in a proximal direction. As can be seen in particular from the Fig. 4 and Fig. As can be clearly seen in Figure 5, two opposing lifting elements 44 are provided, which project radially beyond the sleeve 22. The lifting elements 44 are formed integrally with the sleeve and are designed as extension tongues. For this purpose, a bending point 46 is provided at the base of each tongue, along which the lifting elements 44 are bent outwards in a radial direction. The free ends 48 of the lifting elements 44 face the retaining element 26.

[0036] In the Fig. 6 and Fig. Figure 7 shows the soldering tip assembly 14, where the free ends 48 of the stop means 44 come into contact with the distal end face 50 of the retaining element 26 due to spring force. The end face 50 of the retaining element 26 has radially inwardly projecting shoulders 52, the free ends 54 of which serve to axially guide the sleeve. The free ends 48 of the stop means 44 rest on the distal upper surface of the shoulders 52; the end face 50 and the shoulders 52 thus form a stop limit. As also shown in Figure 7, the free ends 48 of the stop means 44 come into contact with the distal upper surface of the shoulders 52. Fig. As can be clearly seen in Figure 7, the sleeve 22 has axially extending guide contours in the form of beads 56, which are particularly evident in the Fig. 5 and Fig. 7 are visible. Complementary to the grooves 56, radially extending recesses 58 are provided at the free ends 54 of the shoulders 52.

[0037] This has the advantage that the retaining element 26 cannot twist relative to the sleeve 22, thus preventing rotation of the soldering tip 24. This is particularly important for soldering tasks where the soldering tip must be held at a specific angle. Another advantage is that the free ends 48 of the support elements 44 are reliably supported on the shoulders 52.

[0038] As can be seen particularly in the Fig. 5 and Fig. As is clearly shown in Figure 6, in the unmounted, neutral state of the soldering tip assembly 14, the flange section 40 with the opening 60 lies in the same plane as the proximal side 61 of the retaining element 26. This has the advantage that the retaining element 26 is largely protected when the free end of the heating element 18 is inserted. It would also be conceivable for the opening 60 with the flange section 40 to project beyond the retaining element 26 in a proximal direction.

[0039] Fig. Figure 8 shows the soldering tip assembly 14 mounted on the handle 12. To secure the soldering tip assembly 14 to the handle, the rear grip sections 34 are acted upon in a distal direction against the opposing sections 28 with the locking lugs 30 by the spring force of the spring element 38.

[0040] The soldering tip assembly is mounted on the handle 12 as follows: First, the free end 19 of the heating element 18 is inserted into the opening 60 of the sleeve 22. The heating element 18 is inserted into the sleeve 22 and then into the soldering tip 24 until the free end 19 of the heating element 18 presses against a stop section 62 provided in the soldering tip 24. As can be seen from the Fig. 5 and Fig. As can be clearly seen in Figure 8, the soldering tip 24 is designed with a blind hole and has the stop section 62 at its base. After the free end 19 of the heating element 18 acts against the stop section 62, the soldering tip 24 is forced distally against the force of the spring element 38 when the heating element 18 is moved further. Consequently, the retaining element 26 is moved along the longitudinal axis 23 relative to the soldering tip 24 or the heating element 18, against the spring action. Simultaneously, the opposing sections 28 engage in the recesses 32 on the retaining element 26. The retaining element 26 then rotates relative to the heating element 24 about the longitudinal axis 23, so that the opposing sections 28, or rather their lugs 30, come into contact with the rear gripping sections 34. In the assembly position, the locking lugs 30 are then pressed against the mounting sections 36 due to the spring force of the spring element 38.The spring element 38 therefore ensures, firstly, that the free end 19 of the heating element is pressed against the stop section 62 of the soldering tip 24 for reliable heat conduction and, if necessary, temperature measurement, and secondly, that the opposing sections 28 with the locking lugs 30 come into contact with the contact sections 36 of the holding element 26.

[0041] As from the Fig. 1, Fig. 2, Fig. As can be clearly seen in Figures 4, 6, and 7, a coding 64 in the form of a two-dimensional code is provided on the holding element 26. The coding 64 is such that it can be read by a reader and the respective soldering tip 24 or soldering tip assembly 14 can be identified. The holding element 26 has a radially recessed surface 66 on its radial circumference, on which the coding 64 is provided. This protects the coding 64, in particular, from damage or abrasion. The coding can be, in particular, a barcode or QR code printed by pad printing. Alternatively, an RFID chip or tag can be used as the coding.

[0042] In the Fig. 9 and Fig. Figure 10 shows a storage stand 80 for storing the soldering iron 10 and various soldering tip assemblies 14. The storage stand 80 is designed to be placed on a flat surface, in particular a table. The storage stand 80 has a total of four funnel-shaped interchangeable holders 82, 84, 86, and 88 on its upper surface, with a soldering tip assembly 14 being provided in the interchangeable holder 82. Furthermore, a soldering iron receptacle 90 is provided in a central area 89, in which the soldering iron 10 can be placed. The interchangeable holders 82, 84, 86, and 88 are located laterally next to the soldering iron receptacle 90. The storage stand 80 also has compartments 92 on its operator-facing side for storing small parts and accessories, as well as a shelf 93 for soldering tips.

[0043] The 80 mm stand can be a separate unit alongside an electronics station that supplies the soldering iron with electrical power. However, it is also conceivable that the 80 mm stand is formed by or integrated into such an electronics station.

[0044] As especially from Fig. As can be clearly seen in Figure 10, the exchange holders 82, 84, 82, 88 are each designed to taper conically in the distal direction around an insertion axis 94. The cone of the exchange holders 82, 84, 82, 88 is partially complementary to the cone of the retaining element 26, so that the respective soldering tip assembly 14 rests securely in an exchange holder 82, 84, 86, 88 with its retaining section 26. The exchange holders 82, 84, 86, 88 have an insertion opening 96 on their proximal upper surface and a bottom opening 98 on their distal lower surface. The insertion opening 96 is elongated or oval and the bottom opening 98 is round, so that pivoting between the insertion position and a removal position is possible. Overall, the diameter of the insertion opening 96 is larger than the diameter of the bottom opening 98, resulting in the conical shape.

[0045] As can be seen in particular from the section according to Fig. As is clearly shown in Figure 10, anti-rotation elements 100 in the form of ribs are provided on the inner surface of the change holders 82, 84, 86, 88. These ribs lie in planes extending through the insertion axis 94. It is conceivable that one or more ribs are provided. The anti-rotation elements 100 project radially towards the insertion axis 94. Furthermore, the anti-rotation elements 100 are designed to cooperate with the parallel knurling provided on the respective insertion element 26 to prevent rotation of the retaining element 26, or to engage between two knurled ridges 27. However, the anti-rotation elements can also be arranged orthogonally to the axis 94, for example, on the surface of the insertion stop 106.

[0046] A soldering tip assembly 14 inserted into a change holder 82, 84, 86 and 88 is thereby held securely against rotation in the storage stand 80. By providing the total in Fig. The four interchangeable holders 82, 84, 86 and 88 shown in Figure 9 can therefore hold a total of four different soldering tip assemblies 14 in the interchangeable holders 82, 84, 86 and 88 shown there.

[0047] From the section according to Fig. Figure 10 also shows that a retaining element 102 is provided in the area of ​​the respective insertion opening 96. This element serves to retain a soldering tip assembly 14, which is inserted into the respective change holder 82, 84, 86, 88 and pivoted into a pull-off position, when the handle 12 is removed proximally. In the pull-off position, the respective retaining element 102 engages behind a ring shoulder 104 provided on the retaining element 26, so that the retaining element 26, and thus the soldering tip assembly 14, remains securely in the storage stand 80 when the handle is pulled off in a proximal direction. The retaining element 102 is designed as a projection that extends radially towards the insertion axis 94. In order to allow the soldering tip assembly 14 with the ring shoulder 104 to be moved under the retaining element 102, the interchangeable holders 82, 84, 86, 88 are oval-shaped at the insertion opening.The soldering tip assembly can therefore be pivoted or tilted from the insertion axis 94 towards a removal axis 107. It is also conceivable that the retaining elements 102 have a conditional elastic compliance. The retaining element 102 allows the soldering tip assembly 14 to be safely separated from the handle with the heating element, particularly if the soldering tip 24 is stuck to the heating element 18. However, if a soldering tip assembly 14 attached to the handle 12 is to be removed from the respective change holder 82 to 88, this can be done along the axis 94 without damaging the retaining element 26 and / or the retaining element 102.

[0048] How to proceed from the cut according to Fig. As can be clearly seen in Figure 10, insertion stops 106 are provided in the area of ​​the bottom opening 98. The insertion stops 106 serve to ensure that the distal sides of the respective retaining element 26 can come into contact with the proximal upper surface of the respective insertion stop 106. This prevents the retaining element 26 from jamming in the interchangeable holder.

[0049] The insertion stops 106 are designed as projections extending radially towards the insertion axis 94. Furthermore, the design allows the retaining element 26 to pivot or tilt on the surface of the insertion stop 106 between the two axes 94 and 107. Each insertion stop 106 is designed such that the anti-rotation elements 100 remain engaged with the parallel knurling 27 at all times when the retaining element 26 is tilted between the axes 94 and 107, thus preventing the retaining element from rotating during the entire tilting movement.

[0050] The two exchange holders 82 and 86 are designed with open edges and have a lateral opening 108 for the lateral insertion or removal of soldering tip assemblies 14. This allows soldering tip assemblies 14 with a soldering tip whose dimensions are larger than the diameter of the bottom opening 98 to be inserted into the exchange holders 82 and 86.

[0051] By providing for the in the Fig. 9 and Fig. The exchange holders 82 to 88 shown in Figure 10 allow for the simple exchange of a soldering tip assembly 14. A soldering tip assembly 14, mounted on the handle 12, is inserted into an exchange holder 82, 84, 86, or 88 along the axis 94 until the distal side of the retaining element 26 comes to rest against the proximal upper surface of the insertion stops 106. At least one of the anti-rotation elements 100 engages in the parallel knurling 27 provided on the retaining element 26, thus securing the retaining element 26 against rotation in the respective exchange holder 82. If the handle 12 is then actuated further in the distal direction against the spring force of the spring element 34, the opposing sections 28, or their locking lugs 30, disengage from the contact sections 36.To release the bayonet-like attachment of the soldering tip assembly 14 to the handle 12, the handle 12 is rotated relative to the soldering tip assembly 14 until the handle-side counterpart sections 28 engage in the recesses 32 on the retaining element side, and the handle 12, together with the heating element 18, can be removed proximally from the soldering tip assembly 14. Then, if the heating element 18 should be stuck to the soldering tip 24, the handle 12 can be pivoted or tilted about a pivot point 99 from axis 94 towards axis 107 until the retaining element 102, as shown in [reference], is released. Fig. Figure 10 shows the retaining element 26, or rather its ring shoulder 104, engaging behind it. This ensures that the respective retaining element 102 securely holds the soldering tip assembly 14 in the respective change holder 82 to 88 and prevents unintentional removal from the respective change holder 82 to 88.

[0052] If a different soldering tip assembly 14 is to be attached to the handle 12, the heating element 18 can be inserted into the opening 60 of a sleeve 22 of a soldering tip assembly 14 placed on the storage stand 80. The insertion must be carried out in such a way that the mating sections 28 provided on the handle 12 engage in the recesses 32 provided on the retaining element 26. After overcoming the spring force of the spring element 38, the handle 12 is rotated relative to the respective retaining element 26, so that the locking lugs 30 of the mating sections 28 engage with the contact sections 36 of the rear grip sections 34, thus securing the soldering tip assembly 14 to the handle 12 in a bayonet-like manner.

[0053] Once the locking lugs 30 have been attached to the system sections 36, the handle 12, together with the selected soldering tip assembly 14, can be moved out of the respective change holder 82 to 88 in a proximal direction. This movement then occurs along the axis 94.

[0054] The described exchange of the soldering tip assembly 14 has the advantage that the exchange can be carried out without manually touching the holding element 26, and thus without the risk of burns from the holding element 26. The operator only holds the handle 12 of the soldering device 100; the soldering tip assemblies 14 can be safely stored in the respective exchange holders 82 to 88.

[0055] The reader for reading the code 66 provided on the respective soldering tip 14 can also be arranged in or on the storage stand 80. After the soldering tip assembly 14 has been changed, the respective holding element 26 with the code 64 can be passed by the reader so that the respective soldering tip assembly 14, or the associated soldering tip 24, can be identified. In an alternative embodiment, a reader for an RFID chip or tag is installed in the storage stand in order to provide information about the soldering tip used directly when the soldering tip assembly 14 is picked up or changed.
