Description

Technical Field

[0001] The present invention relates to an apparatus and a method for joining two joining partners, in particular synthetic resin parts, by quasi-simultaneous laser welding.

Background Art

[0002] Synthetic resin or refers to parts made of synthetic resin, or and workpieces made of synthetic resin or semi-finished products have important significance in today's production. Such synthetic resin parts are employed in various technical fields such as vehicle technology, robotics, machine manufacturing, and home appliance technology. However, in several manufacturing steps, it is often necessary to connect two or or more synthetic resin parts. This can be carried out, for example, by adhesive connection, and for example, by mechanical fixing methods such as screws, rivets, clips, etc. However, today, for example, welding two parts or joining partners to each other, especially inseparably connecting or by welding is increasing. In addition, various welding methods can be used for such welding, for example, laser welding, high-temperature gas welding, a method using a hot plate, infrared welding, ultrasonic welding, and friction welding, etc. can be adopted.

[0003] In high-temperature gas welding, usually, the joining partners to be welded are each set on a work carrier suitable for the production. At that time, the so-called "feeding unit" opens, and the welding process itself is started by extending the heating element to the heating position. Subsequently, the connection area is heated by radiant heat orThe diathermy phase (induction heating phase) in which the joining zone is plasticized is carried out. The heat conduction of the heating element to the joining seam is forced by a high-temperature shielding gas flow. After the necessary heat of fusion has been applied to the synthetic resin parts, the feed means move away from each other to such an extent that the heating element can return from the working position to the standby position. The joining process itself is carried out by closing the supply unit so that the plasticized and welded-defined shape can be fused. A predefined joining path is monitored so that the welded parts have the correct final dimensions with certainty.

[0004] Furthermore, two synthetic resin parts can also be welded to each other using a heated tool plate. At this time, welding ribs on the opposite joining partner or The welding bead comes into contact with the tool of the heating plate. Heat is sent to the welding rib and melts it. Subsequently, the heating plate is removed, and the joining partners are pressed against each other until they are joined. In the case of infrared welding (IR welding), the joining partners are firmly held near the infrared radiation plate to melt the joining surface. The plate is removed, and the half-parts can be pressed against each other and solidified again under pressure. However, high-temperature gas welding, the heating plate method, and infrared welding have the disadvantages in the prior art that they require high technical costs and that heat cannot be selectively applied to the welding site. In addition, a long tact time is required, and high energy costs are also required.

[0005] In ultrasonic welding, the required welding heat is generated by the pressure and ultrasonic vibration between the parts to be connected. After plasticization, the synthetic resin melted under pressure solidifies, thereby forming a uniform welded joint. However, this method is not suitable for component groups containing electronic components because the electronic components may be damaged by ultrasonic waves. In addition, for example, dust that may cause contamination is generated, including in the case of electronic components. In friction welding, the required welding heat is generated by the pressure and friction between the parts to be connected. After plasticization, the melted resin material solidifies, and a uniform welded joint is obtained. However, friction welding also generates dust and is not suitable for component groups containing electronic components.

[0006] The principle of laser welding is that the laser beam penetrates and is absorbed by the joining partner that transmits the laser beam, and the laser beam is focused on the joining partner. At this time, the laser beam is converted into heat and plasticizes the material. The volume increases and contacts the transparent partner. Due to the resulting heat conduction, the transparent joining partner is locally plasticized. To obtain good heat conductivity between both joining partners and, as a result, a good welded joint, it is usually necessary to attach a fixing plate that presses both joining partners against each other during laser irradiation. That is, in this method for laser welding synthetic resin, it is premised on a joining partner that transmits the laser and a joining partner that absorbs the laser. Joining components, or , one of the joining partners must be transparent to the laser. Therefore, synthetic resin that is transparent to the laser is often expensive, especially when the synthetic resin parts must be, for example, blackened, which may increase the manufacturing cost.

[0007] From CN 107 471 657 A, a laser welding method for welding non-transparent thermoplastic synthetic resins where two non-transparent parts are welded by a laser is known. Here, in the welding process, pressure is applied to the parts. In this laser welding method, the upper synthetic resin part to be welded and the lower synthetic resin part to be welded are such that the upper synthetic resin module and the lower synthetic resin module are overlapped and pressed against each other by pressure. Then, the laser beam is focused on the upper synthetic resin part so that a heating region is formed. At that time, the laser beam is set such that the temperature of the heating region is lower than the melting point of the upper synthetic resin part and higher than the melting point of the lower synthetic resin part. Thereby, the heat of the heating region is radiated to the lower synthetic resin module, melts accordingly, and due to the effect of the pressure, this is connected to the upper synthetic resin part.

Problems to be Solved by the Invention

[0009] That is, the problem of the present invention is that by using it, synthetic resin parts, particularly preferably parts groups containing electronic parts, can be joined to each other easily, highly efficiently and inexpensively, thereby overcoming the drawbacks of the prior art, and providing an apparatus and method for connecting synthetic resin parts.

Means for Solving the Problems

[0010] The above problems are solved by the combined teachings of claim 1 and the parallel independent claims. Embodiments suitable for the purpose of the present invention are claimed in the dependent claims.

[0011] The present invention relates to thermally inputting two joining partners, particularly synthetic resin partsor claims the right to an apparatus for joining by means of quasi-simultaneous laser welding. In this case, the apparatus includes a first heat source arranged to heat the joining surface of a first joining partner, and a second heat source arranged to heat the joining surface of a second joining partner. Further, there are provided a first component receiving means for receiving the first joining partner and a second component receiving means for receiving the second joining partner, where the first component receiving means is rotatably arranged about a first rotation axis and the second component receiving means is rotatably arranged about a second rotation axis. At this time, the first component receiving means is arranged at least essentially vertically with respect to the second component receiving means, that is, the first rotation axis is also arranged essentially at a right angle to the second rotation axis. In addition, the first component receiving means has a heating position where the first joining partner is arranged with respect to the heat source such that the joining surface of the first joining partner can be heated by the first heat source. Similarly, the second component receiving means also has a heating position where the second joining partner is arranged with respect to the heat source such that the joining surface of the second joining partner can be heated by the second heat source. The apparatus provides a joining position where the joining surfaces of the first and second joining partners are arranged facing each other, and by rotating the first component receiving means about the first rotation axis, or vertically intersect arranged so that, that is, the first joining partner can be placed in the joining position, and by rotating the second component receiving means about the second rotation axis, or rotatably, the second joining partner can also be placed in the joining position, so that the first and second joining partners can be joined, especially after heating. The joining surface can be moved by the first component receiving means, or a part of the first component receiving means, or for example, a part of the first component receiving means can be moved towards the second component receiving means side, and by the second component receiving means, or a part of the second component receiving means (e.g., or a part of the first component receiving means and can be moved towards the second component receiving means side), orA joining unit that can move a part of the second component receiving means towards the first component receiving means is employed so that they can be combined with each other. The joining surfaces are positioned to contact each other by the movement of the joining unit. or and are positioned so as to be able to contact each other.

[0012] In addition, the joining surfaces are such that the joining unit or moves a part of the first component receiving means along the first rotation axis and and is preferably moved in a direction along the second rotation axis so that the joining surface of the first joining partner and the joining surface of the second joining partner are positioned to contact each other and thus combined with each other.

[0013] Alternative or Additionally, the joining surfaces are such that joint unit or one joining unit or moves a part of the second component receiving means along the first rotation axis and and is also able to be moved in a direction along the second rotation axis so that the joining surface of the first joining partner and the joining surface of the second joining partner are positioned to contact each other and thus combined with each other.

[0014] In addition, as the first heat source, a laser and / or and it is preferable that a laser is provided as the second heat source. Additionally, it is possible to equip with all devices suitable for heating the joining surfaces known in the prior art as heat sources.

[0015] Furthermore, the component receiving means can each receive a plurality of joining partners, particularly preferably two or four joining partners. Similarly, the component receiving means can have a plurality of component seats. As a result, the advantage is obtained that the joining partners can be set, heated, joined, and taken out in parallel or and almost simultaneously. According to a further advantageous form, the component receiving means is a turntable rotatably arranged about a rotation axis orIt can include a rotating table. The turntable can, in that case, have any shape (circular, square, hexagonal, etc.) and any thickness. Furthermore, the turntable can be an electric motor, particularly preferably a servo motor, and can be actuated via hydraulic control.

[0016] In addition, it is reasonable for the component receiving means to include at least one component seat for receiving one of the mating partners.

[0017] Also, the component seat can have a receiving part suitable for fixing the component, particularly a vacuum gripper, a magnet mechanism, and which can advantageously include a clamp for securely holding the component or mating partner. Furthermore, this makes it possible to move the component "upside down" on the turntable without removing it from the component. In addition, the joining unit can include a turntable, or , a stamp that contacts the component seat, and by transmitting the joining force to the stamp, the turntable and / or and it is preferable that the component seat can move in a direction along the first rotation axis.

[0018] Also, the joining unit preferably includes a motor drive or hydraulic drive.

[0019] According to a preferred embodiment of the present invention, one component receiving means can be arranged horizontally and one component receiving means can be arranged vertically.

[0020] Furthermore, it is also possible to provide two vertically and oppositely arranged component receiving means. Similarly, it is also possible to provide an additional heat source for two additional vertical component receiving means.

[0021] Furthermore, for each heat source, it is also reasonable to provide an independent monitoring system, particularly preferably a thermographic camera, to monitor the heating of the joining partners respectively. As a result, each component can be monitored individually and can respond to errors individually (for example, by changing only the output of one heat source), so that the advantage of accurate monitoring can be obtained.

[0022] Furthermore, the component receiving means can each have an individual joining unit, but the joining surfaces of the joining partners are such that each joining unit contacts the joining surface by the movement of the joining unit, with each component receiving means, or a part of which is combined with each other by moving it. As a result, the advantage of saving tact time can be obtained, but the heating phase, or the heating can be shortened, for example.

[0023] The present invention claims, in parallel independent and dependent claims, a method for joining two joining partners. This is particularly preferably implemented by the device according to the present invention. Here, the method has the following method steps: - A step of setting a first joining partner in the first component receiving means and a second joining partner in the second component receiving means; - Positioning the first component receiving means about a first rotation axis such that the first joining partner is arranged in a heating position where the joining surface of the first joining partner is heated by the first heat source, and further positioning the second component receiving means about a second rotation axis such that the second joining partner is arranged in a heating position where the joining surface of the second joining partner is heated by the second heat source; [[ID=z18]]- The first heat source is provided and arranged to heat the joining surface of the first joining partner, or and the second heat source is arranged to heat the joining surface of the second joining partner by being arranged; - rotating the first component receiving means about a first axis of rotation so that the first joining partner is in the joining position and rotating the second component receiving means about a second axis of rotation so that the second joining partner is in the joining position, wherein the joining surfaces of the first and second joining partners are arranged in facing joining positions; - connecting the mating surface to the first component receiving means or is a part of the first part receiving means or the second part receiving means or or joining the first joining partner and the second joining partner by moving a part of the second part receiving means into contact with each other. For this purpose, for example, a joining surface of the first joining partner is brought into contact with the first part receiving means, and a joining unit for bringing the joining surface of the second joining partner into contact with the joining surface of the second joining partner by movement of a portion of the first component receiving means along the first axis of rotation; and A joining unit may also be provided for bringing a portion of the second part receiving means into contact with a joining surface of the second joining partner by movement of the portion of the second part receiving means along the first axis of rotation. and is possible for both movements (due to each part receiving means having a respective joining unit); and - Removing the connected mating partner.

[0024] Preferably, each of the component receiving means accommodates a plurality of joining partners, particularly preferably two or three. or The component receiving means can also have a plurality of component seats, so that the component partners can be arranged in parallel, or This provides the advantage of allowing for quasi-simultaneous setting, heating, bonding, and removal.

[0025] In particular, the joining partner can be removed from the component receiving means and placed in the component receiving means in parallel with the heating, in particular by placing another joining partner in the component receiving means and / or and removes two connected junction partners, andIn parallel with removing the completed synthetic resin product, at least one joining partner is heated.

[0026] Furthermore, the present invention can be used for manufacturing a sensor unit provided with a housing, particularly a radar sensor or a lidar sensor for capturing the surroundings of a vehicle or other means of transportation. In this case, the housing includes two joining partners joined using the device according to the present invention or and the method according to the present invention.

[0027] In the present invention, the expression "along the axis of rotation" is interpreted, in particular, as the direction of the axis of rotation or and the extension line in the longitudinal direction of the axis of rotation. This means that, for example, when the axis of rotation passes through the center of the turntable of the component receiving means or the component nest or component seat arranged outside the turntable is moved for one joining stroke along the axis of rotation (i.e., in the direction of the axis of rotation, that is, perpendicular or vertically with respect to the turntable) to join and or bring into contact with the joining partner.

[0028] Thereby, the present invention provides an energy source orIt advantageously enables the creation of a method (process) and an apparatus for welding two opaque plastic parts (by laser welding) using a laser as a heat source. In this case, the application can be optimized with respect to material flow and tact time in a simple and cost-effective manner when introducing it into mass production. By designing the apparatus dedicatedly and parallelizing (quasi-simultaneously) individual processes, it is possible to optimize it for mass production. In the joining method according to the present invention, since they are not damaged, the method is particularly suitable for joining component groups containing electronic components. This case further relates to a process without dust although known ESD requirements must be met. That is, it is possible to advantageously utilize the robustness of laser technology for joining synthetic resins without depending on whether one joining partner is transparent or not. At that time, a selective heat path can be formed at the joining interface. In addition, when changing the design of the components, since no additional tool change or new tool manufacturing is required, the flexibility of the technology can be enhanced.

[0029] The present invention can be employed, for example, in the following fields (needless to say, this list is not limited): automobiles, aerospace, medical technology, electronics, etc., in any field where it is necessary to weld two synthetic resin parts to achieve functions. As a result, the present invention can contribute very particularly to the field of welding synthetic resin parts (by laser).

[0030] Hereinafter, the present invention will be described in more detail by way of embodiments suitable for the purpose. Description of the drawings:

DETAILED DESCRIPTION OF THE INVENTION

[0032] Figure 1 shows a device 1 according to the present invention. The device 1 includes two positioning systems, or , here the first component receiving means 2 and the second component receiving means 3 which can also be called horizontal receiving means and vertical receiving means according to the arrangement. The first component receiving means 2 is configured to receive the first joining partner 4, and the second component receiving means 3 is configured to receive the second joining partner 5. Further, the first component receiving means 2 and the second component receiving means 3 are each configured to receive four components or joining partners 4a - 4d or 5a - 5d. The device 1 is then configured to join the joining partners 4, 5 made of synthetic resin along the surface of the joining surface. The joining surface is then composed of the joining surfaces 6, 7 of the joining partners 4, 5 connecting the joining partners 4, 5 to each other. The joining surfaces 6, 7 then form a continuous surface, and which may have interruptions or and may have bulges. For the joining process, the device 1 includes a first heat source implemented as a laser 8 arranged to heat the joining surface 6 of the first joining partner 4, and a second heat source implemented as a laser 9 arranged to heat the joining surface 7 of the second joining partner 5, i.e., the joining surfaces 6, 7 are melted, if necessary, in order to weld to each other, andis heated so as to be partially melted.

[0033] The first component receiving means 2 is here rotatably arranged about the first rotation axis 10, and the second component receiving means 3 is arranged rotatably about the second rotation axis 11. The rotation is indicated in the figure by the thick black arrow, but the direction of rotation can be determined according to the application. The component receiving means 2, 3 can each receive four components or Since the joining partners can be received, the component receiving means 2, 3 must be able to rotate about their respective rotation axes by about 90 degrees in one position change. The first component receiving means 2 is arranged at least essentially perpendicular to the second component receiving means 3. In short, the component receiving means 2, 3 designed planar at the mounting level are substantially straight intersect with each other, and thus the first rotation axis 10 and the second rotation axis 11 are also substantially straight intersect so as to or be straight intersect at right angles (assembly tolerance + / - 0 to 5 degrees, particularly preferably + / - 0 to 3 degrees). The first component receiving means 2, and also the second component receiving means 3 each have a heat position arranged such that their respective joining partners 4, 5 face the corresponding lasers 8, 9, and their joining surfaces 6, 7 are heated by the lasers 8, 9 (indicated by the thin black arrows in the figure).

[0034] Furthermore, the first joining partner 4 and the second joining partner 5 are combined with each other by being placed in a joining position such that after heating, the joining surface joining positions 6, 7 of the first joining partner 4 and the second joining partner 5 face each other. At this time, the first component receiving means 2 is rotated 90 degrees about the first rotation axis 10 so that the first joining partner 4 comes to the joining position, and the second component receiving means 3 is rotated 90 degrees about the second rotation axis 11 so that the second joining partner 5 comes to the joining position. As a result, as shown in detail in Figure 2, the joining surfaces 6, 7 are arranged to face each other. These joining surfaces 6, 7 are the first component receiving means 2, or, a part of the first component receiving means 2 is movably arranged along the first rotation axis 10 so as to be combined with each other. Here, the first joint surface 6 is the first component receiving means 2, or is brought into contact with the second joint surface 7 of the second joint partner 5 by the movement (indicated by the white arrow) of a part of the first component receiving means 2 along the first rotation axis 10.

[0035] Horizontal receiving means, or , as shown in FIG. 3, the first component receiving means 2 is (horizontally arranged) a turntable 21 rotatably arranged about the first rotation axis 10, and if necessary, a base plate 22 for the component seat, a component seat 23 for supporting the first joint partner, and a motor and can be driven hydraulically, and includes a stamp 24 for applying a force, that is, for performing a movement (joint stroke) for joining. The application of the force (arrow F) is preferably performed from below with respect to the fixedly provided joint unit. That is, the first component receiving means 2 includes a guided component receiving means capable of performing a planned joint stroke. That is, here, not the entire component receiving means 2 is moved along the first rotation axis 10 toward the second joint partner, but only the component seat 23 is moved together with the first joint partner 4.

[0036] Vertical receiving means, or , as shown in FIG. 4, the second component receiving means 2 is (vertically arranged) a turntable 31 rotatably arranged about the second rotation axis 11, and if necessary, a base plate 32 for the component seat, and a component seat 33 for supporting the second joint partner 5. The component seat 33, at that time, has component fixing means suitable for receiving (not shown for clarity), for example, a vacuum gripper, a magnet mechanism (especially for non-metallic synthetic resins having permanent magnet properties and magnetic bodies coated with synthetic resins), and includes a clamp mechanism for the component, or , in order to hold the second joint partner 5 and to counteract gravity and centrifugal force, is preferably configured to be included.

[0037] At this time, the joining movement is not explicitly limited to the "from bottom to top" joining movement (in the figure description). In particular, when the first component receiving means is arranged vertically and the second component receiving means is arranged horizontally, the joining movement can also be "from top to bottom" (in the figure description, this means that the joining partner 5 and the component receiving means 33 are pressed against the joining partner 4 from above). In addition, both component receiving means can be used with a joining unit to perform the joining movement (in order, or simultaneously), that is, each component receiving means has its own joining unit and both move.

[0038] By dividing individual processes into individual process stations, for example, the removal and setting of component receiving means 2 and 3 can be carried out (so-called quasi-simultaneously) in parallel with the (laser) heating process, enabling mass production optimized with respect to the tact time. Furthermore, in existing processes for welding plastics of opaque components where the energy source does not touch the welding surface (such as hot gas welding or infrared welding), energy and heat cannot be directly concentrated on the welding surface. On the other hand, methods that can directly concentrate energy / heat (such as ultrasonic welding or friction welding) have drawbacks such as generating a lot of dust and / and when the component group contains electronic components, having the possibility of damaging them. In contrast, the proposed invention relates to a selective synthetic resin welding method that can directly concentrate energy / heat on the welding interface, or the joining surface.

[0039] The method according to the present invention includes, at that time, method steps such as laser heating (heating), positioning or rotation (switching), pressing and cooling (clamping and cooling), and processes such as the setting and removal (loading / unloading) of component or joining partners.

[0040] In the laser heating step, both components to be welded orThe joining partners 4, 5 are heated, or , warmed. The heating must be carried out from the correct direction for each joining partner - for this purpose, the lasers 8, 9 are correctly positioned, or , and can be designed to be movable. Thus, each joining partner 4, 5 is equipped with dedicated laser equipment and can select and independently set the necessary process parameters. In addition, it is also possible to employ a monitoring system for each, for example, a thermographic camera (not shown), to monitor both heating processes and recognize possible negative effects.

[0041] After the heating is completed, especially after the lasers are turned off, both joining partners 4, 5 are positioned (by rotating the rotary table or turning tables 21, 31) to a joining position where the heated joining partners 4, 5 face each other but are not yet in contact (in short, at this time, the part receiving means 2, 3 are rotated by 90 degrees respectively).

[0042] Furthermore, at the joining position, it is reasonable to provide a joining unit that can enable the implementation and monitoring of an optimal "pressing process" (pressing) on the melted surface with variable joining speed and joining pressure. The joining partners 4, 5 are such that the heated material between the parts does not deform due to the lack of pressure, and or , this state (i.e., pressed against each other) must be maintained until both parts are permanently joined (cooled) materially. At this time, it is also possible to provide active cooling (for example, cooling by an air flow).

[0043] During loading and unloading, the set of both joining partners for an automated material flow is carried out by a suitable handling system, for example, an industrial robot or an axial portal in the empty part receiving means, etc. (for example, in the figure, the joining partners 4c / 4d orThe position of the component seats of 5c / 5d - depending on the number of component seats used and the positioning system used).

[0044] Figure 5 shows a system with two component receiving means, each component receiving means capable of setting three component or joining partners, i.e., each having three component seats). or A flowchart of the method according to the present invention for the device is illustrated. Thus, for each position change, each turntable is rotated 120 degrees.

[0045] Furthermore, instead of the two turntables 21, 31, it is also conceivable to use other types of article transport circulation systems (for example, a programmable drive system equipped with a linear motor and having, for example, a "mover" capable of running an endless loop with a variable number without depending on each other). The number of component seats 23, 33 (so-called "stations" or "nests") used on the turntables 21, 31, as well as the rotation direction of the article transport system, can be freely selected and adapted to the application. The spatial arrangement / orientation of the joining structure within the space is variable and can also be adapted to each application.
