Description

Technical Field

[0001] This invention relates to an apparatus and method for joining two splicing parts, particularly by means of quasi-synchronous laser welding of plastic parts. Background Technology

[0002] Plastics, plastic parts, plastic components, and plastic semi-finished products play a vital role in modern production. These plastic parts are widely used in various technical fields, such as automotive technology, robotics, machinery manufacturing, and household appliance technology. In a single production step, it is often necessary to join two or more plastic parts together. This can be achieved, for example, through adhesive bonding or mechanical fastening methods such as screws, rivets, or clips. However, welding techniques are increasingly being used, for example, to connect or join two components or fittings together, especially in a non-separable manner. Various welding methods can be used, such as laser welding, hot gas welding, hot plate welding, infrared welding, ultrasonic welding, or friction welding.

[0003] In hot gas welding, the two components to be welded are typically placed separately in product-specific workpiece carriers. Here, the feed device is activated, initiating the actual welding process by moving the heating element into the heating position. This is followed by a through-heating (full heating) phase where the joining or splicing area is plasticized by thermal radiation. Heat is forced from the heating element to the weld seam via a protective gas flow. After the necessary molten heat is applied to the plastic part, the feed device disengages until the heating element moves from the working position to the resting position. The feed device is then closed, allowing the plasticized, defined weld geometry to fuse together, thus implementing the actual splicing process. The predetermined splicing path is monitored to ensure the welded parts have the correct final dimensions.

[0004] In addition, two plastic parts can be welded together using a heating tool plate. During welding, the heating tool, i.e., the heating plate, brings the weld beads or weld beads on the opposite splicing parts into contact. Heat is directed to the weld beads and melts them. The heating plate is then removed, and the splicing parts are pressed together until they are joined. In infrared welding (IR welding), the splicing parts are fixed near an infrared radiating plate to melt the splicing surfaces. The radiating plate is removed, the two halves of the parts are pushed together, and re-cured under pressure. The disadvantages of existing hot gas welding, heating plate, and infrared welding technologies are high technical costs and the inability to selectively provide heat to the welding interface. Furthermore, they require long welding cycle times and high energy consumption.

[0005] In ultrasonic welding, the required welding heat is generated by the pressure and ultrasonic vibration between the parts to be joined. After plasticization, the molten plastic solidifies under pressure, thereby forming a uniform weld joint. However, this method is not suitable for assemblies containing internal electronic components, as these components may be damaged by the ultrasonic waves. Furthermore, ultrasonic welding can generate particles that may increase contamination of electronic components. In friction welding, the required welding heat is generated by the pressure and friction between the parts to be joined. After plasticization, the molten plastic material hardens, forming a uniform weld joint. However, friction welding is also unsuitable for assemblies containing internal electronic components, as this welding method also generates particles.

[0006] The basic principle of laser welding is that a laser beam penetrates a laser-transmitting splicing component and focuses on an absorptive splicing component. Here, the laser beam is converted into heat and plasticizes the material. The increasing volume contacts the laser-transmitting splicing component. The resulting heat transfer causes localized plasticization of the laser-transmitting splicing component. To ensure good thermal conductivity between the two splicing components and ultimately form a good weld joint, a fixing plate is usually placed during laser irradiation to press the two splicing components together. Therefore, the prerequisite for laser welding of plastics is the need for both a laser-transmitting splicing component and a laser-absorbing splicing component. One of the splicing components or a splicing component must be laser-transmitting, which may increase manufacturing costs because laser-transmitting plastics are generally expensive, especially when the plastic part is, for example, black.

[0007] A laser welding process for non-transparent welding of thermoplastics is known from CN 107 471 657A. In this method, two non-transparent parts are welded by a laser, wherein the two parts are held together by pressure during the welding process. In this laser welding method, the upper and lower plastic parts to be welded are positioned by stacking the upper and lower plastic modules and pressing them together with pressure. A laser beam is then focused on the upper plastic part, forming a heating zone. The laser beam is then adjusted so that the temperature of the heating zone is lower than the melting point of the upper plastic part but higher than the melting point of the lower plastic part. The heat from the heating zone radiates to the lower plastic module, causing it to melt accordingly, thus joining the lower and upper plastic parts together under pressure. Summary of the Invention

[0008] The objective of this invention is to provide an apparatus and method for joining plastic parts, which can connect plastic parts, especially components containing electronic components, to each other in a simple, efficient, and cost-effective manner, thereby overcoming the disadvantages of the prior art.

[0009] The aforementioned task is solved through the overall theory of claim 1 and the independent claim. In the dependent claims, the design of the invention is claimed according to the intended use.

[0010] This invention claims a device for joining two splicing components together, particularly a device for welding splicing components by means of input heat or for welding plastic parts using a quasi-synchronous laser. To this end, the device includes a first heat source and a second heat source, the first heat source being configured to heat the splicing surface of the first splicing component, and the second heat source being configured to heat the splicing surface of the second splicing component. Furthermore, a first component fixing device for receiving the first splicing component and a second component fixing device for receiving the second splicing component are pre-positioned, wherein the first component fixing device is configured to rotate about a first rotation axis, and the second component fixing device is configured to rotate about a second rotation axis. Here, the first component fixing device is at least substantially perpendicular or orthogonal to the second component fixing device, and therefore the first and second rotation axes are also configured to be substantially perpendicular to each other. In addition, the first component fixing device has a heating position, in which the first splicing component is positioned relative to the first heat source such that the splicing surface of the first splicing component can be heated by the first heat source. Correspondingly, the second component fixing device also has a heating position, in which the second splicing component is positioned relative to the second heat source such that its splicing surface can be heated by the second heat source. Then, especially after heating, the device can splice the first and second splicing components together by setting a splicing position. In this splicing position, the splicing surfaces of the first and second splicing components are positioned opposite each other. The first component fixing device rotates around the first rotation axis, or can rotate around the first rotation axis, thereby placing the first splicing component in the splicing position. The second component fixing device rotates around the second rotation axis, or can rotate around the second rotation axis, thereby placing the second splicing component in the splicing position as well. Here, the splicing surfaces are joined together by pre-setting a splicing device, which can move a first component fixing device or a part of the first component fixing device, or can move a second component fixing device or a part of the second component fixing device (for example, the first component fixing device or a part of the first component fixing device can move toward the second component fixing device, or the second component fixing device or a part of the second component fixing device can move toward the first component fixing device), wherein the splicing surfaces are brought into contact by moving the splicing device.

[0011] A preferred method for merging splicing surfaces is to move the first component fixing device or a part of the first component fixing device along the direction of the first rotation axis or the second rotation axis by the splicing device, so that the splicing surface of the first splicing accessory contacts the splicing surface of the second splicing accessory.

[0012] As an alternative or additional measure, the splicing surfaces can also be merged together by moving the second component fixing device or a part of the second component fixing device along the first rotation axis or along the second rotation axis of the splicing device, so that the splicing surface of the first splicing accessory comes into contact with the splicing surface of the second splicing accessory.

[0013] Preferably, one laser is pre-positioned as a first heat source and / or another laser is pre-positioned as a second heat source. Furthermore, all known prior art devices suitable for heating spliced ​​surfaces can also be pre-positioned as heat sources.

[0014] Furthermore, each component fixing device can accommodate multiple splicing accessories, particularly two, four, or more. Correspondingly, the component fixing device can also include multiple component seats. The advantage of this is that the splicing accessories can be loaded, heated, assembled, and unloaded in parallel or quasi-synchronously.

[0015] According to a favorable design, the component fixing device may include a turntable or disc platform configured to rotate about a rotation axis. Here, the turntable can be of any shape (circular, rectangular, hexagonal, or similar) and of any thickness. Furthermore, the turntable may be driven, for example, by an electric motor, particularly a servo motor, or a hydraulic control system.

[0016] Suitablely, the component fixing device may include at least one component seat for placing the splicing accessories.

[0017] In a beneficial manner, the component holder may include a component securing device suitable for placement, particularly a vacuum suction cup, a magnetic mechanism, or a clamping device, to securely and reliably hold the component or assembly. This also prevents the component from falling off the component holder during "elevated" transport on a turntable.

[0018] The splicing device preferably includes a plunger that contacts the turntable or component seat and transmits the splicing force to the plunger, thereby moving the turntable and / or component seat along the first rotation axis.

[0019] Suitablely, the splicing device may include an electric or hydraulic drive.

[0020] According to a preferred design of the present invention, a horizontal component fixing device and a vertical component fixing device may be provided.

[0021] In addition, two opposing, vertical component fixing devices can be pre-installed. Correspondingly, an additional heat source can be pre-installed for the additional second vertical component fixing device.

[0022] Suitable practice is to pre-install a separate monitoring system, particularly a thermal imaging camera, for each heat source to monitor the heating status of the splicing components individually. The advantage of this is that monitoring can be exceptionally precise because each component is monitored individually, and faults can be addressed in a personalized manner (e.g., a change in the power of only one heat source).

[0023] Furthermore, each component fixing device has its own splicing device, wherein each splicing device moves its corresponding component fixing device or a part thereof, thereby bringing the splicing surfaces of the splicing accessories together, and the movement of the splicing device brings the splicing surfaces into contact with each other. The advantage of this is that it can shorten the cycle time, for example, by shortening the heating stage or heating time.

[0024] Furthermore, the independent or dependent claims of this invention also claim protection for a method of splicing two splicing parts. This method is implemented, in particular, by an apparatus according to the invention. Here, the method comprises the following steps:

[0025] - Load the first splicing accessory onto the first component fixing device, and load the second splicing accessory onto the second component fixing device;

[0026] - Position the first component fixing device around a first rotation axis in the heating position. In this heating position, the first splicing accessory is arranged relative to the first heat source in such a way that the splicing surface of the first splicing accessory is heated by the first heat source. Position the second component fixing device around a second rotation axis in the heating position. In this heating position, the second splicing accessory is arranged relative to the second heat source in such a way that the splicing surface of the second splicing accessory is heated by the second heat source.

[0027] - Heating is performed by pre-setting or setting a first heat source to heat the splicing surface of the first splicing component, and heating is performed by setting a second heat source to heat the splicing surface of the second splicing component.

[0028] - Rotate the first component fixing device around the first rotation axis to place the first splicing accessory in a splicing position, and rotate the second component fixing device around the second rotation axis to place the second splicing accessory in a splicing position as well, wherein the splicing positions of the splicing surfaces of the first splicing accessory and the second splicing accessory are opposite to each other;

[0029] - By moving the first component fixing device or a portion thereof, or by moving the second component fixing device or a portion thereof, the splicing surfaces are brought into contact, thereby achieving the splicing of the first splicing accessory and the second splicing accessory. For example, a splicing device can be pre-positioned for this purpose, and the splicing surface of the first splicing accessory can be brought into contact with the splicing surface of the second splicing accessory by moving the first component fixing device or a portion thereof along the first rotation axis. Furthermore, the splicing surface of the second splicing accessory can also be brought into contact with the splicing surface of the second splicing accessory by moving the second component fixing device or a portion thereof along the first rotation axis. Additionally, other movement configurations or lateral movement can be considered (e.g., thus each component fixing device has a splicing device); and

[0030] - Uninstall interconnected splicing components.

[0031] The component fixing device is preferably capable of accommodating multiple splicing components, particularly two, three, or four splicing components each. Therefore, the component fixing device can also include multiple component seats. The advantage of this is that splicing components can be loaded, heated, assembled, and unloaded in parallel or quasi-synchronously.

[0032] In a beneficial manner, particularly the unloading and loading of component fixing devices with splicing fittings, can be carried out in parallel with heating, wherein at least one splicing fitting is heated while the component fixing device loads another splicing fitting and / or unloads two splicing fittings that have been connected together or unloads a plastic finished product.

[0033] Furthermore, the present invention can also be used to manufacture sensor devices with a housing, particularly radar or lidar sensors for detecting the environment around vehicles or transport vehicles. Here, the housing comprises two splicing fittings joined together using the device described in the present invention or by means of the method described in the present invention.

[0034] In the context of this invention, "along the axis of rotation" specifically refers to the direction of the axis of rotation or the longitudinal direction of the axis of rotation. This means, for example, that if the axis of rotation passes centrally through the component fixing device or the turntable of the component fixing device, the component recess or component seat located in the area outside the turntable can also be moved along the axis of rotation (i.e., moved along the direction of the axis of rotation, that is, moved in a manner approximately perpendicular or orthogonal to the turntable) via the splicing path to achieve splicing or contact of the splicing components.

[0035] Therefore, the present invention can advantageously construct a method (process) and apparatus, using which lasers can also be used as energy or heating sources (laser welding) to weld two non-transparent plastic parts. Consequently, material flow and cycle time can be optimized more simply and cost-effectively in mass production: through a special design of the related apparatus, mass production optimization can be achieved by parallelizing (quasi-synchronously) a single process. The method is also particularly suitable for welding components containing internal electronic components, as the connection process according to the invention does not damage the internal electronic components. Furthermore, a particle-free process is designed here, wherein the process meets known electrostatic discharge (ESD) protection requirements. Therefore, the robustness of laser technology can be advantageously used for welding plastics without considering the transparency of the joined parts. Here, a selective thermal path can be formed at the weld interface. Furthermore, technical flexibility can be improved when component designs change, wherein it is not necessary to replace or manufacture new tools.

[0036] Furthermore, this invention can also be used in, for example, the following fields (an explicit non-limiting list): automotive, aerospace, medical technology, electronics, and all fields where two plastic parts must be welded to achieve their function. Therefore, this invention makes a very special contribution to the field of (laser) welding of plastic parts. Attached Figure Description

[0041] Figure 4 A simplified schematic diagram of a vertically mounted component fixing device design is shown for the apparatus according to the present invention, and

[0042] Figure 5A simplified schematic diagram of the flowchart of the device according to the present invention is shown, wherein each component fixing device has three component seats. Detailed Implementation

[0043] Figure 1 The device 1 shown is based on the present invention. Device 1 includes two positioning systems, or a first component fixing device 2 and a second component fixing device 3, which, due to their arrangement, can also be referred to as horizontal placement and vertical placement. The first component fixing device 2 is used to place a first splicing accessory 4, and the second component fixing device 3 is used to place a second splicing accessory 5. Furthermore, the first component fixing device 2 and the second component fixing device 3 are configured to hold four components or splicing accessories 4a to 4d or 5a to 5d, respectively. Here, device 1 is configured to splice plastic splicing accessories 4 and 5 together along a surface serving as a splicing surface. Here, the splicing surface is formed by the splicing surfaces 6 and 7 of the splicing accessories 4 and 5, which are interconnected on the splicing surfaces 6 and 7. Here, the splicing surfaces 6 and 7 can form a continuous surface, or they can be discontinuous or raised. During the splicing process, the device 1 includes a first heat source in the form of a laser 8 for heating the splicing surface 6 of the first splicing component 4, and also includes a second heat source in the form of a laser 9 for heating the splicing surface 7 of the second splicing component 5. That is, the splicing surfaces 6 and 7 are heated, thereby melting or partially melting if necessary, and then welded together.

[0044] Here, the first component fixing device 2 is configured to rotate around a first rotation axis 10, and the second component fixing device 3 is configured to rotate around a second rotation axis 11. The rotation is indicated by thick black arrows in the figure, and the direction of rotation can be determined according to the application. Since component fixing devices 2 and 3 can each hold four components or splicing parts, they must rotate approximately 90 degrees around their respective rotation axes to change their positions. The first component fixing device 2 is at least substantially perpendicular to the second component fixing device 3; that is, the mounting planes of the surface-type component fixing devices 2 and 3 are substantially orthogonal to each other, thereby ensuring that the first rotation axis 10 and the second rotation axis 11 are also substantially perpendicular or at right angles (component tolerances of + / -0 degrees to 5 degrees, especially 0 degrees to 3 degrees). Both the first component fixing device 2 and the second component fixing device 3 have a heating position. At the heating position, the corresponding splicing components 4 and 5 and the corresponding lasers 8 and 9 are arranged such that the splicing surfaces 6 and 7 of the splicing components can be heated by the lasers 8 and 9 (indicated by thin black arrows in the figure).

[0045] Furthermore, by pre-setting a splicing position, the splicing surfaces 6 and 7 of the first splicing component 4 and the second splicing component 5 are positioned opposite each other, thereby merging the first splicing component 4 and the second splicing component 5 together after heating. For this purpose, the first component fixing device 2 rotates 90 degrees around the first rotation axis 10, thereby placing the first splicing component 4 in the splicing position, and the second component fixing device 3 rotates 90 degrees around the second rotation axis 11, thereby placing the second splicing component 5 also in the splicing position, thus... Figure 2 As shown, the splicing surfaces 6 and 7 are arranged opposite each other. Then, the splicing surfaces 6 and 7 can be joined together by setting the first component fixing device 2 or a part of the first component fixing device 2 in a manner movable along the first rotation axis 10, wherein the first splicing surface 6 contacts the second splicing surface 7 of the second splicing accessory 5 by moving the first component fixing device 2 or a part of the first component fixing device 2 along the first rotation axis 10 (as shown by the white arrow).

[0046] like Figure 3 As shown, the horizontal placement device or first component fixing device 2 includes a (horizontally positioned) turntable 21 configured to rotate about a first rotation axis 10, and, if necessary, a component base plate 22, a component seat 23 carrying the first splicing accessory, and a plunger 24 for applying force to perform the splicing movement (splicing stroke), the plunger being, for example, driven by a motor or hydraulic system. Here, the application of force (as indicated by arrow F) is preferably performed from below by a fixedly mounted splicing device. Therefore, the first component fixing device 2 includes a guide component fixing device to ensure precise splicing stroke, i.e., the entire component fixing device 2 does not move along the first rotation axis 10 towards the second splicing accessory, but only the component seat 23 carrying the first splicing accessory 4 moves.

[0047] like Figure 4 As shown, the vertical placement device or second component fixing device 2 includes a (vertically positioned) turntable 31 rotatable about a second rotation axis 11, and if necessary, a component base plate 32 and a component seat 33 for supporting the second splicing accessory 5. Here, the component seat 33 is preferably configured to include a component fixing device (not shown in the figure for clarity), such as a vacuum suction cup, a magnetic mechanism (especially a non-metallic plastic with permanent magnetism or a magnetic material coated with plastic), or a clamping mechanism, to hold the component or second splicing accessory 5 and resist gravity and centrifugal force.

[0048] Here, the splicing motion is not limited to an "upward" splicing motion (see figure); in particular, the first component fixing device can be set vertically and the second component fixing device can be set horizontally, thereby enabling a "downward" splicing motion (see figure, which means that the splicing accessory 5 with component fixing device 33 presses downward onto the splicing accessory 4). In addition, the two component fixing devices can also complete a corresponding splicing motion (one after another or simultaneously) with the aid of a splicing device, i.e., bilateral motion, where, for example, each component fixing device has a splicing device.

[0049] By implementing a single process at a single process station, batch production with optimized cycle times can be achieved because, for example, the unloading and loading of component fixing devices 2 and 3 are performed in parallel (quasi-synchronously) with the (laser) heating process. Furthermore, existing methods for welding non-transparent plastic components (such as hot gas welding or infrared welding) do not involve the energy source in contact with the welding surface, making it impossible to directly focus energy or heat onto the welding surface. Conversely, methods that can directly focus energy / heat onto the welding surface (such as ultrasonic welding or friction welding) have the disadvantage of generating a large number of particles and / or, if the component contains electronic components, the potential for damage to those components. In contrast, this invention specifically relates to a selective plastic welding method in which energy / heat is directly focused onto the welding interface or splicing surface.

[0050] Here, the method according to the present invention includes steps such as laser heating, positioning or rotation (switching), clamping and cooling, and loading / unloading of components or splicing accessories.

[0051] During laser heating, the two components or splicing parts 4 and 5 to be welded are heated. Here, heating should be performed at the correct angle according to the specific characteristics of each splicing part; for this purpose, lasers 8 and 9 can be set accordingly, or can be made movable. Therefore, each splicing part 4 and 5 is pre-installed with its own laser device, allowing for the selective and independent setting of necessary process parameters. Furthermore, depending on the specific circumstances, a monitoring system (not shown), such as a thermal imaging camera, can be separately installed to monitor the two heating processes and identify potential negative impacts.

[0052] After heating ends, especially after the laser is turned off, the two splicing parts 4 and 5 enter the splicing position by a rotational motion (via the disc table or turntable 21, 31) during positioning, until the two heated splicing parts 4 and 5 are in a relative position that has not yet come into contact (i.e., the component fixing devices 2 and 3 rotate 90 degrees accordingly).

[0053] Suitablely, a splicing device is pre-installed, which can adjust (clamp) and monitor the optimal "clamping process" of the molten surface at the splicing position with variable splicing speed and splicing force. During this stage, splicing components 4 and 5 must remain clamped (i.e., clamped together) until the heated material can no longer deform on its own or due to lack of pressure between the components, and the two components are thus permanently and materially locked together (cooling and molding). Active cooling (e.g., by means of airflow cooling) can also be provided here.

[0054] During loading and unloading, the two splicing components for automated material flow are preferably placed in an unoccupied component fixing device by a suitable handling system, such as an industrial robot or a multi-axis gantry (e.g., the component seat positions of splicing components 4c / 4d or 5c / 5d in the figure, depending on the number of component seats used and the positioning system used).

[0055] Figure 5 The diagram illustrates a flowchart of a method according to the present invention, which is applicable, for example, to a system or apparatus with two component fixing devices, wherein each component fixing device can hold three components or splicing accessories, i.e., each component fixing device has three component seats. Therefore, to change the position, each corresponding turntable needs to be rotated 120 degrees.

[0056] Furthermore, it is conceivable to replace the two turntables 21 and 31 with other product-carrying circulation systems (e.g., a freely programmable drive system using linear motor technology, on which a variable number of "mover" units can move independently of each other in an endless cycle). The number of component seats 23 and 33 (so-called "bases" or "recesses") used on turntables 21 and 31 and the rotation direction of the product-carrying system can be variably selected and adapted to the application. The spatial arrangement / orientation of the splicing structure is variable and can also be adjusted according to the relevant applications.
