Description

The invention relates to a manufacturing plant for components. In manufacturing plants for the production of, for example, vehicles, surfaces or other critical components of parts are monitored with regard to manufacturing quality in order to ensure high production quality. For example, an image-based inspection system for surface inspection is known from US 2014 / 0 333 778 A1. From JP 2022-86 149 A, a manufacturing plant with a device for monitoring the production is known, wherein the device is equipped with an image capture device and more than three lighting elements. WO 2024 / 154 931 A1 discloses a device which operates on the principle of photometric stereo and can be used in a production environment. From EP 4 603 225 A1 and JP 2011-154 436 A, a production plant with a large number of cameras is known. The disadvantage is that monitoring production using known inspection systems is costly, slow and unreliable. The technical problem is to create a manufacturing plant for components that can monitor production cost-effectively, quickly and reliably. The solution to the technical problem is provided by the subject matter with the features of the main claim. Further advantageous embodiments of the invention are described in the dependent claims. A manufacturing plant for components is proposed, comprising: - at least one manufacturing section and - a plurality of devices for monitoring the manufacturing process, wherein the devices are fixedly arranged at various positions within the at least one manufacturing section, wherein each device is assigned to at least one monitoring area within the at least one manufacturing section, wherein each device has at least one image acquisition device and at least three lighting elements, wherein each device is configured to illuminate the respective monitoring area and to capture at least one image of the at least one component in the respective monitoring area, wherein the manufacturing plant is configured to perform a shape-based inspection procedure for the respective monitoring area based on the at least one image in order to monitor the manufacturing of the component. The manufacturing system offers the advantage of cost-effective, fast, and reliable monitoring of production processes using a multitude of devices. This is achieved by arranging the devices in various positions, enabling them to monitor different areas of the production line from a fixed location. This eliminates the need for an industrial robot, which would otherwise have to move, for example, the image acquisition device to the various monitoring areas. Furthermore, the fixed arrangement of the devices allows for the disregard of safety tolerances that would otherwise be necessary when using an industrial robot. Production monitoring is also more time-efficient, as the monitoring sections can be monitored simultaneously using the numerous devices.Furthermore, the shape-based inspection method can detect fine surface structures and height differences on the component. This improves reliability and accuracy compared to purely two-dimensional inspection methods. The production facility is primarily used for manufacturing vehicle components. The vehicle could be, for example, an electric vehicle. The component could be, for example, the vehicle's electrical system or a part thereof. For instance, numerous devices monitor whether connectors between wiring harnesses in the vehicle's electrical system are correctly engaged. The production facility can be configured to manufacture a component group for the vehicle or the entire vehicle. The production facility can have multiple production sections, for example, thirty. In each production section, at least one manufacturing step and / or assembly step can be performed on the component. The component and / or the vehicle can be transported along the production facility from one production section to another, for example, by means of an automated transport robot or a conveyor system. The at least one production section in which the multitude of devices are arranged is, in particular, a final production section of the manufacturing plant. This ensures that the manufacturing of the component is almost complete before monitoring takes place. For example, all connectors to be monitored are already in place before the component is monitored in the final production section. In this final production section, monitoring by means of the multitude of devices allows for a final production inspection, which, for example, concludes the production process with the release of the component, the component group, or the vehicle. The image acquisition device can be a 2D camera. The image acquisition device can have an integrated circuit. The image acquisition device can have a resolution of, for example, 0.1 to eight megapixels. The at least three lighting elements can each be designed as an LED. Each lighting element can illuminate the component from a different angle or direction. In particular, the at least three lighting elements can produce red-green-blue (RGB) lighting, for example, using a red LED, a green LED, and a blue LED. Alternatively, the lighting elements can also produce white light lighting, for example, using white LEDs. The image can depict an area of ​​the component where, for example, connectors have been made. The image can be, for example, an RGB image, where the red, green, and blue spectra are distinguishable. For this purpose, an image sensor of the image acquisition device can have at least three separate color channels and, for example, be designed as a Bayer pattern sensor. However, the image can also be a black and white image of the component, for example, if the component is illuminated with white light. The shape-based inspection method can be a so-called shape-from-shading inspection method. Shape-from-shading inspection methods are familiar to those skilled in the art. In this method, the component is illuminated simultaneously with red, green, and blue light, and an image of the component is captured to perform the shape-based inspection. Alternatively, the component is illuminated with white light, for example, several times in succession, and a corresponding image is captured for each illumination. From the captured images, so-called albedo images, P-images, and / or Q-images can be generated, which can be used, for example, to determine a shape and / or height profile of the component. Using the determined shape and / or height profile, a connector can, for example, be monitored for insufficient engagement or misalignment. For instance, the determined shape and / or height profile is compared with a reference shape and / or height profile of the component.The evaluation of the captured image (at least one) can be performed using a local evaluation unit on the device or a central evaluation unit on the production plant. Both the local and the central evaluation units can be implemented as microcontrollers. The device can have a communication interface, particularly a wireless one, for communication with a central unit on the production plant, such as the central evaluation unit. The monitoring area of ​​a given device can be limited by a section of the component that can be represented by the image. This section of the image can represent the area of ​​the component to be monitored. The area of ​​the component to be monitored can, for example, be a partial surface of the component. The monitoring area can, for example, have a size ranging from 100 mm x 100 mm to 1000 mm x 1000 mm on the surface of the component. This allows the partial surface to be monitored to be between 100 mm x 100 mm and 1000 mm x 1000 mm in size. One or more connectors to be monitored can be arranged on this partial surface of the component. The monitoring areas can be disjoint from each other, meaning they do not overlap. The devices can be specifically designed for their assigned monitoring area. For example, properties of the respective device—such as...For example, the resolution of the image acquisition device must be matched to the assigned monitoring area. This improves the accuracy of production monitoring. In particular, the device can detect defects as small as 200 micrometers within the respective monitoring area. In one embodiment, at least one device is located less than 400 mm from the component being monitored. This small distance between the component and the device allows the device to operate, for example, with a lower resolution image acquisition device and / or less intense illumination to adequately resolve or illuminate the component. The distance of less than 400 mm can, for example, be the distance between a bottom surface of the device and a top surface of the component. In particular, all devices in the plurality of devices are located less than 400 mm from the component being monitored. In one embodiment, at least one image acquisition device of at least one apparatus has a resolution of less than eight megapixels, in particular less than four megapixels, and further, in particular, less than two megapixels. This reduces the manufacturing costs of the image acquisition device and decreases the amount of data generated during monitoring, which in turn facilitates the evaluation of the captured images. In particular, each apparatus of the plurality of apparatus has at least one image acquisition device with a resolution of less than eight megapixels, in particular less than four megapixels, and further, in particular, less than two megapixels. In one embodiment, at least one device has a maximum electrical power consumption of less than 1000 watts, in particular less than 500 watts, and further, in particular less than 250 watts. This limits the electrical power required for monitoring production, which in turn reduces energy costs. Specifically, each device in the plurality of devices has a maximum electrical power consumption of less than 1000 watts, in particular less than 500 watts, and further, in particular less than 250 watts. The power consumption of the device is particularly low because, as explained above, the device can be positioned very close to the component, allowing the device components to be smaller. For example, the at least three lighting elements can be operated simultaneously with less than 400 watts.The maximum power consumption also limits the maximum current within the device. This allows cables within the device to have a smaller cross-sectional area. The device can be powered via a power connection. This power connection can be a magnetic connector. This prevents damage to power plugs or similar components, for example, if the power supply is accidentally disconnected. The device's supply voltage can be, for example, 12 volts or 24 volts. The device can have one or more voltage converters that convert the supply voltage into one or more operating voltages. The operating voltage of the image capture device can be, for example, 5 volts. The operating voltage of the lighting elements can be, for example, 32 volts. Each lighting element can be operated with a maximum current of, for example, four amperes. In one embodiment, at least one device has a maximum dimension of less than 100 mm. In particular, each device in the plurality of devices has a maximum dimension of less than 100 mm. In this way, the installation space requirement of the plurality of devices in the at least one manufacturing step can be kept as low as possible. The maximum dimension can be, for example, a maximum height, maximum width, and / or maximum depth of a housing for the device. The maximum dimension of the device can, for example, be determined as the edge length of the housing. In other words, the device requires no more than 100 mm of installation space in any spatial direction. The installation volume of the device can thus be limited to 1000 cubic centimeters. In one embodiment, the at least one manufacturing section is divided into monitoring areas and at least one manufacturing area. This allows for a reduction in the manufacturing and / or assembly time of the component, as production does not need to be paused for monitoring. In particular, the manufacturing area is separate from the monitoring areas to prevent, for example, interference with monitoring due to parallel production. For instance, welding work or the assembly of additional components can be carried out in parallel with monitoring in the manufacturing area. Furthermore, the manufacturing system is specifically designed to monitor production in the monitoring areas using a plurality of devices while the system performs at least one manufacturing and / or assembly step in the at least one manufacturing area, for example, using an industrial robot. In one embodiment, the manufacturing system comprises at least one sensor device, wherein the manufacturing system is configured to determine the position of the at least one component in the at least one manufacturing section by means of the at least one sensor device, and the plurality of devices are controlled depending on the position of the at least one component. In this way, it can be ensured that the component is in a position suitable for monitoring before the monitoring begins. The position suitable for monitoring can also be referred to as the monitoring position. The sensor device can, for example, be configured as or include one or more time-of-flight sensors or magnetic sensors. The sensor device can also be referred to as a position determination device. The sensor device can, for example, be configured as a position sensor or a position determination device.The sensor device detects the distance between itself and the component or the transport robot. For example, the production system can define a component position as a monitoring position if the detected distance to the component or the transport robot is less than a predefined threshold. The multitude of devices can be controlled, for example, by a central control unit of the production system. The production system can, for example, control when the multitude of devices start monitoring their respective monitoring areas. For example, the central control unit can send a control signal, configured as a start signal, to the multitude of devices when the component is positioned in the monitoring position. The central control unit can communicate wirelessly with the multitude of devices, for example, via a Bluetooth or WLAN interface. In one embodiment, at least one device has at least one trigger device, and the manufacturing system is configured to initiate monitoring of the monitoring area using the at least one device when the at least one trigger device generates at least one trigger signal. This ensures that the device is ready for monitoring. For example, the trigger signal can be generated when the at least one trigger device detects the presence of the at least one component in the monitoring area. In one embodiment, at least one device has at least one switching device, wherein the production system is configured to control the switching on and off of the at least three lighting elements by means of the at least one switching device. In this way, the lighting elements can be switched on and off in sync with the production cycle or as needed. This reduces the energy consumption of the device. The switching device can be designed as a relay, e.g., a solid-state relay. In particular, the device can have at least one switching device for each lighting element. This allows each lighting element to be switched on and off individually. This is particularly advantageous if the lighting elements produce white light and / or an image is to be captured using illumination from a single lighting element. In particular, the production plant includes at least one visual and / or acoustic output device, and the production plant is configured to output a monitoring result by means of this at least one output device. The monitoring result can be, for example, a positive or a negative result. A positive monitoring result can be the release of the entire component. A negative monitoring result can be the non-release of the entire component. However, the result can also relate to a part of the component or a monitored area. A monitoring result for the monitored area can be negative, for example, if a connector in the monitored area has not been manufactured correctly. This can be the case, for example, if the shape and / or height profile of a connector does not match the reference shape and / or height profile of the connector.The output device can be a warning signal transmitter that, for example, emits a red warning light and / or a warning tone if the monitoring result is negative, allowing an operator to intervene in the production process and correct the connection. If, on the other hand, the monitoring result is positive, a green warning light and / or no warning tone can be emitted. In particular, each device has an output device so that, for example, the operator can immediately see in which monitoring area intervention in the production process is necessary. The invention is explained in more detail with reference to an exemplary embodiment. The figures show: Fig. 1 a schematic representation of an embodiment of a production plant with a plurality of devices, Fig. 2 a schematic representation of an embodiment of a device for monitoring a production process, Fig. 3-A a schematic representation of a further embodiment of a device for monitoring a production process, Fig. 3-B a schematic representation of a further embodiment of a device for monitoring a production process in a sectional plane, Fig. 4-A a schematic representation of a further embodiment of a device for monitoring a production process, Fig. 4-B a schematic representation of a further embodiment of a device for monitoring a production process in a sectional view. In the following, identical reference symbols denote elements with the same technical characteristics. Fig. 1 shows a schematic representation of an embodiment of a manufacturing plant 100 with a plurality of devices 1, 2, 3. Production plant 100 is used to manufacture identical components 10 for an electric vehicle (not shown). The component 10 to be manufactured is, for example, a high-voltage electrical system or a part thereof. Devices 1, 2, and 3 are identical and serve to monitor the manufacturing process of component 10. Using the multiple devices 1, 2, and 3, it is possible, for example, to monitor whether the connectors between the cable leads (not shown) of component 10 are correctly engaged. The production plant 100 has several production sections 20, 30, and 40. The component 10 is arranged on a transport robot 50, which transports the component 10 from the first production section 20 to the further production sections 30 and 40. In Fig. 1, a transport robot 50 with a component 10 is shown in each production section 20, 30, and 40. Production section 40 can be a final production section of the production plant 1000. In each of the production sections 20, 30, 40, at least one production step is carried out, such as the production of the plug connections or welding work, so that the production of component 10 progresses from production section 20, 30, 40 to production section 20, 30, 40. Devices 1, 2, and 3 are fixedly arranged at different positions within production section 40, such that each device 1, 2, and 3 monitors its own monitoring area W1, W2, and W3. Each monitoring area W1, W2, and W3 is, for example, a partial surface of component 10 when component 10 is located in production section 40. In addition to monitoring areas W1, W2, and W3, production section 40 also has a separate production area F1, which is also a sub-area of ​​component 10. Production of component 10 can continue in parallel with monitoring in this separate production area F1. Each device 1, 2, 3 has at least one image acquisition device K designed as a 2D color camera and at least three illumination elements B1, B2, B3. This is shown in Fig. 1 in the enlarged section G for device 1. The illumination element B1 can be, for example, a green LED, the illumination element B2 can be, for example, a blue LED, and the illumination element B3 can be, for example, a red LED. Each of the devices 1, 2, 3 is designed to illuminate the respective monitoring area W1, W2, W3 simultaneously with red, green and blue light by means of the lighting elements B1, B2, B3, so that an RGB image 11, 12, 13 of the at least one component 10 in the respective monitoring area W1, W2, W3 is captured by means of the image acquisition device K. The production system 100 is configured to perform a shape-based inspection procedure for the respective monitoring areas W1, W2, W3 based on the captured image 11, 12, 13, in order to monitor the production of component 10. The shape-based inspection procedure can, for example, be a so-called shape-from-shading inspection procedure. For this purpose, the production system 100 can include a central control or evaluation unit (not shown). Alternatively, the shape-based inspection procedure can also be performed on the fixtures 1, 2, 3, for example, on a local control or evaluation unit (not shown in Fig. 1) of the respective fixture 1, 2, 3. The production system 100 is specifically designed to determine the current position of component 10 within production section 40 based on a sensor reading from a sensor device 104. The sensor device 104 can, for example, be configured as one or more magnetic sensors within production section 40, which, for example, detect the presence of component 10 or the transport robot 50. Monitoring of the monitoring areas W1, W2, and W3 can be initiated depending on the position of at least one component 10. For this purpose, the central control unit (not shown) of the production system 100 can, for example, issue a start signal for monitoring when it has been determined that component 10 is in a so-called monitoring position within production section 40. In the monitoring position, each of the devices 1, 2, 3 is positioned at a distance D of less than 400 mm from component 10. This allows a resolution of less than eight megapixels for the image acquisition device K to be sufficient, for example, to detect defects smaller than 200 micrometers in length. Due to the small distance, other electronic components of devices 1, 2, 3, such as the lighting elements B1, B2, B3, can also be small, so that each device 1, 2, 3 has a maximum electrical power consumption of less than 250 watts. The small size of the electrical components of devices 1, 2, 3, in turn, allows the maximum dimension A – for example, the width – of device 1 to be less than 100 mm. In other words, the fixed arrangement of devices 1, 2, 3 in production section 40 makes it possible to position the devices 1, 2, 3 very close to component 10.This allows the devices 1, 2, 3 to be specifically tailored to their assigned monitoring area W1, W2, W3, so that the devices 1, 2, 3 can be built extremely compactly and economically without sacrificing accuracy. Fig. 2 shows a schematic representation of an embodiment of a device 1 for monitoring a production process. The device 1 has an image acquisition device K and three lighting elements B1, B2, B3. Furthermore, the device 1 can have one or more of the following electronic components: - a local control device 4, which is e.g. designed as a microcontroller, - a trigger device 5, which can e.g. sensorily detect the presence of an object near the device 1 according to the time-of-flight principle, - a switching device 6 for switching the lighting elements B1, B2, B3 (lighting element B3 is not shown in Fig. 2 for clarity), - a power connection 7, which is e.g. designed as a magnetic connection and serves to supply power to the device 1 (power lines within the device 1 are shown as solid lines between the components), - an energy storage device 8, e.g. designed as a lithium-ion battery, which serves as a buffer battery in the event of a short-term power failure.Naturally, a charge controller (not shown) can also be provided for charging the energy storage device 8; a communication interface 9, which is designed, for example, as a USB, WLAN, or Bluetooth interface and which serves, for example, for communication with a central control or evaluation unit (not shown) of a production plant 100 (see Fig. 1); a first voltage converter 15 designed as a rectifier, which serves to convert a supply voltage of, for example, 24 volts into an operating voltage of, for example, five volts; a further voltage converter 16 designed as a rectifier, which serves to convert a supply voltage of, for example, 24 volts into an operating voltage of, for example, 32 volts; and a housing H, which is designed, for example, as a metal housing and serves to arrange the device 1 in a production section 40 of the production plant 100. The manufacturing costs of device 1 can be less than €300 due to the small size of the electronic components. The device 1 can be permanently installed in the production section 40, for example by screwing the housing H to a profile rail (not shown). In the production section 40 (see Fig. 1), the device 1 is assigned to a monitoring area W1. The monitoring area W1 can, for example, be a partial surface of a top surface O of a component 10 to be monitored. The top surface O of the component 10 can be positioned at a distance D of less than 400 mm from a bottom surface U of the device 1 in a monitoring position. The device 1 is specifically designed to perform the following monitoring steps: When component 10 is transported into production section 40 during manufacturing and is positioned under the device 1, e.g., in the monitoring position, the trigger device 5 can detect the presence of component 10. The trigger device 5 then generates a trigger signal T, which is transmitted, e.g., to the local control unit 4 (shown by a dashed line in Fig. 2). Subsequently, for example, a first control signal S1 is generated by means of the local control unit 4, which actuates the switching device 6, so that the lighting elements B1, B2, B3 are energized and the monitoring area W1 is illuminated. While the monitoring area W1 is illuminated, for example by means of the local control unit 4 another control signal S2 is generated, which activates the image acquisition device K, so that an image 11 of the illuminated component 10 is captured (see Fig. 1 ). The trigger device 5 thus ensures that the illumination of the monitoring area W1 and the capture of the image 11 only take place when the component 10 is in the monitoring position. Subsequently, the captured image 11 can be transferred, for example, via the communication interface 9 to the central control or evaluation unit (not shown) of the production plant 100 in order to carry out a form-based inspection procedure (see explanations for Fig. 1). Fig. 3-A shows a schematic representation of another embodiment of a device 1 for monitoring a production process. Figure 3-A shows a bottom surface U of the device 1. It also shows that three lighting elements B1, B2, B3 are arranged in a circle around an opening L and are offset from each other at an angle of 120°. This results in illumination from different angles. The lighting elements B1, B2, B3 can, for example, emit RGB light. For further explanation of the device 1, a sectional view in a section plane BB is shown in Fig. 3-B. Fig. 3-B shows a schematic representation of another embodiment of a device 1 for monitoring a production process in the section plane BB. Figure 3-B shows that the lighting elements B1, B2, B3 are arranged in a housing H, which may be made of metal, for example, and which dissipates heat from the lighting elements B1, B2, B3 via cooling fins C and releases it into the environment. The lighting elements B1, B2, B3 are arranged in the housing H such that the illumination light is emitted laterally onto a curved reflector R. The reflector R is coated, for example, with a reflective coating of barium sulfate. The reflector R reflects the illumination light (indicated by lines in Figure 3-B) from the lighting elements B1, B2, B3 towards a monitoring area W1 (see Figures 1 and 2). A diffuser M is arranged on an underside U of the device 1, through which the reflected illumination light is diffused. This improves the illumination of component 10. Light reflected from a surface of a component 10 (see Fig. 1 and Fig. 2) can be captured as an image 11 of the component 10 using an image capture device K. Fig. 4-A shows a schematic representation of another embodiment of a device 1 for monitoring a production process. In contrast to Fig. 3-A, four lighting elements B1, B2, B3, B4 are arranged around an opening L in a housing H of the device 1 and are each offset from one another at an angle of 90°. This allows the illumination light to be projected onto the surface of a component 10 from four different directions (see Fig. 1 and Fig. 2). The lighting elements B1, B2, B3, B4 can, for example, emit white light. For further explanation of the device 1, a sectional view in a section plane BB is shown in Fig. 4-B. Fig. 4-B shows a schematic representation of another embodiment of a device 1 for monitoring a production process in the section plane BB. In Fig. 4-B it can be seen that, in contrast to Fig. 3-B, the lighting elements B1, B2, B3, B4 are arranged in the housing H in such a way that the lighting light is emitted directly onto a diffuser M.
