Description

Technical Field

[0001] This invention relates to the field of labeling technology, and more particularly to an automatic labeling device for automotive parts. Background Technology

[0002] In the manufacturing process of automotive parts, labels are usually affixed to the parts. These labels record data such as the part's batch number, supplier information, production date, and unique serial number. By scanning the labels, the assembly line can automatically verify the part model, and the warehouse can manage inbound and outbound operations. When a vehicle has a quality defect, the company can quickly locate the problematic batch and implement a targeted recall based on the label information.

[0003] Currently, when labeling parts, adhesive is typically applied to the surface of the parts first, and then the label is pressed onto the glued parts. For example, patent document CN109229689B discloses a labeling machine for automotive parts. This labeling machine includes a frame, a conveyor belt with grooves for positioning parts, and a storage box, cleaning wheels, a second drying housing, an adhesive applicator, a label unwinding roll, a conveyor roller, a push plate, a cutter, and a pressing rod arranged sequentially above the frame. During operation, the push rod pushes the parts from the storage box into the grooves. The parts are first wet-rubbed by the cleaning wheels along the conveyor belt, then dried by hot air, and then adhesive is applied at the adhesive applicator. The label is fed above the parts by the unwinding roll, the push plate, in conjunction with the cutter, cuts the label, and the pressing rod presses the label down onto the parts. Finally, the parts fall into the collection box, achieving automatic labeling.

[0004] As can be seen, the aforementioned labeling machine can automatically apply adhesive and automatically press and stick labels, improving labeling efficiency. However, in actual production, a large number of labels are self-adhesive labels with their own pressure-sensitive adhesive layer. The labeling process requires first applying a primer to the surface of the component to enhance adhesion strength, and then directly pasting the self-adhesive label onto the primer area. The adhesive applicator of the aforementioned labeling machine is designed for applying adhesive, and cannot achieve precise thin-layer application and uniform coverage of the primer, still requiring manual operation. Manual operation is not only labor-intensive, but the application and drying of the primer also depend on the operator's experience, making it difficult to ensure uniform primer application, drying effect, and consistent placement, resulting in low overall labeling efficiency. Summary of the Invention

[0005] This invention provides an automatic labeling device for automotive parts, which solves the technical problem that the coating and labeling process of adhesive labels in the prior art relies on manual labor, resulting in low labeling efficiency.

[0006] To solve the above problems, the automatic labeling equipment for automotive parts provided by the present invention adopts the following technical solution: An automatic labeling device for automotive parts includes a frame and a control mechanism, with a conveying mechanism for conveying parts mounted on the frame; The frame is provided with a spraying mechanism, a visual inspection mechanism, a baking mechanism, and a labeling mechanism arranged in a straight line along the conveying direction of the conveying mechanism. The control mechanism is signal-connected to the conveying mechanism, the spraying mechanism, the vision inspection mechanism, the baking mechanism, and the labeling mechanism, for controlling the conveying mechanism to convey parts, and sequentially controlling the spraying mechanism to spray a base coat on the parts, controlling the vision inspection mechanism to detect whether the base coat is qualified, controlling the baking mechanism to heat the base coat, and controlling the labeling mechanism to stick a label onto the base coat.

[0007] The beneficial effects of the automatic labeling equipment for automotive parts provided by this invention are: First, by setting up a spraying mechanism and connecting it to a control mechanism, the control mechanism drives the spraying mechanism to automatically and quickly spray the primer evenly onto the surface of the parts according to a preset program and parameters. This eliminates the need for manual operation, thus reducing the intermittent and fatigue associated with manual operation, improving spraying efficiency, and resulting in a more consistent coating thickness.

[0008] Secondly, by setting up a visual inspection mechanism and a baking mechanism downstream of the spraying mechanism on the frame, the visual inspection mechanism can be used to determine whether the coating of the base layer is qualified, avoiding the subjectivity of manual visual inspection and with high efficiency; the baking mechanism heats and cures the base layer, which can significantly shorten the curing time and improve the overall labeling efficiency compared to manually waiting for the paint to dry naturally.

[0009] Furthermore, by setting up a labeling mechanism, labels can be pressed down and pasted onto parts coated with a primer layer. This is more efficient than manual labeling, and the chemical reaction between the primer layer and the label adhesive can enhance the adhesion of the label to the parts.

[0010] Finally, the spraying mechanism, vision inspection mechanism, baking mechanism, and labeling mechanism are arranged in a straight line along the conveying direction of the conveyor. The control mechanism receives signals from each mechanism and precisely controls the start and stop speed of the conveyor, the spraying parameters of the spraying mechanism, the detection logic of the vision inspection mechanism, the temperature and time of the baking mechanism, and the labeling action of the labeling mechanism. This ensures seamless connection between each workstation, eliminating the need for manual switching between different processes, guaranteeing the continuity of labeling, reducing the labor intensity of workers, and improving labeling efficiency.

[0011] In summary, the present invention effectively solves the technical problem that the coating and labeling process of adhesive labels in the prior art relies on manual labor, resulting in low labeling efficiency.

[0012] Furthermore, the conveying mechanism is provided with multiple support platforms for supporting components, and the multiple support platforms are spaced apart on the conveying mechanism.

[0013] Furthermore, the conveying mechanism includes a first conveying component, a conveying transfer component, and a second conveying component arranged sequentially along its conveying direction. The first conveying component and the second conveying component are arranged in parallel and connected through the conveying transfer component. The spraying mechanism, the visual inspection mechanism, the baking mechanism, and the labeling mechanism are arranged sequentially along the conveying direction of the second conveying component.

[0014] Beneficial effects: By setting up parallel first and second conveyor components, and sequentially arranging the spraying mechanism, vision inspection mechanism, baking mechanism, and labeling mechanism along the conveying direction of the second conveyor component, the two paths of empty return flow of the carrier platform and processing of parts are separated. The first conveyor component is dedicated to the fast return channel of the empty carrier platform, while the second conveyor component serves as the conveying channel for labeling processing of parts. The first and second conveyor components operate independently and do not interfere with each other, saving the amount of carrier platform used.

[0015] Specifically, if the first and second conveying components operate synchronously, each conveying component must operate uniformly according to the slowest process's cycle time. Since time-consuming processes such as applying primer, visual inspection, baking, and labeling all occur while the parts are being conveyed on the second conveying component, the second conveying component's conveying speed is relatively slow. In this case, to ensure continuous labeling, the first conveying component needs to be equipped with the same number of support platforms as the second conveying component, resulting in a larger overall number of support platforms required. The first and second conveying components provided in this application operate independently. By increasing the conveying speed of the first conveying component, the conveying time of the support platforms on the first conveying component can be reduced, thereby ensuring a continuous supply of parts to the second conveying component without increasing the number of support platforms on the first conveying component. Ultimately, this reduces the investment cost of support platforms while ensuring continuous labeling.

[0016] Furthermore, the first conveying assembly includes a first drive motor, a first active synchronous pulley, a first driven synchronous pulley, a second driven synchronous pulley, a first driven roller, and a first synchronous belt; the first synchronous belt engages with the first active synchronous pulley, the first driven synchronous pulley, and the second driven synchronous pulley for transmission, and also engages with the first driven roller for frictional transmission; the first drive motor is connected to the first active synchronous pulley for driving the first synchronous belt to move in order to convey the components; the first synchronous belt engages with the support platform for transmission.

[0017] Beneficial effects: On the one hand, the meshing of the first synchronous belt with the first driving synchronous pulley, the first driven synchronous pulley, and the second driven synchronous pulley ensures pitch accuracy during transmission, enabling the platform to move according to the set step length and speed, avoiding positional deviations. On the other hand, the frictional transmission between the first synchronous belt and the first driven roller has a certain buffering and overload protection capability. When the platform's operation is obstructed or the load changes abruptly, relative sliding can occur between the first driven roller and the first synchronous belt, preventing rigid damage and improving the reliability and safety of equipment operation. Furthermore, the direct meshing transmission between the platform and the first synchronous belt eliminates the need for additional clamping or positioning mechanisms, simplifying the structure, reducing manufacturing costs, and minimizing maintenance requirements.

[0018] Furthermore, the second conveying assembly includes a second drive motor, a second active synchronous pulley, a third driven synchronous pulley, a fourth driven synchronous pulley, a second driven roller, and a second synchronous belt; the second synchronous belt engages with the second active synchronous pulley, the third driven synchronous pulley, and the fourth driven synchronous pulley for transmission, and also engages with the second driven roller for frictional transmission; the second drive motor is connected to the second active synchronous pulley for driving the second synchronous belt to move in order to convey the components; the second synchronous belt engages with the support platform for transmission.

[0019] Furthermore, the spraying mechanism includes a first multi-axis displacement structure and a spraying assembly. The first multi-axis displacement structure is mounted on the frame, and the spraying assembly is mounted on the first multi-axis displacement structure so that the spraying assembly is driven to move by the first multi-axis displacement structure to apply a primer coating to the parts conveyed by the conveying mechanism.

[0020] Beneficial effects: The spraying assembly is mounted on the first multi-axis displacement structure, which drives the spraying assembly to move freely in three-dimensional space. When the size, shape, or surface contour of the parts delivered by the conveying mechanism changes, the first multi-axis displacement structure can adjust the spatial position and attitude of the spraying assembly in real time, so that the spraying assembly always maintains a set distance and angle with the surface of the parts, thereby ensuring that the primer coating is applied evenly without any missed or over-spraying.

[0021] Furthermore, the baking mechanism includes a hot air generator for drying the base coating on the parts delivered from the spraying mechanism.

[0022] Furthermore, the labeling mechanism includes a labeling structure and a second multi-axis displacement structure. The labeling structure is mounted on the second multi-axis displacement structure so that the labeling structure is driven to move through the second multi-axis displacement structure to affix labels to the parts.

[0023] Beneficial effects: By installing the labeling structure on the second multi-axis displacement structure, when the size, outline, or labeling position of the parts conveyed by the conveying mechanism changes, the second multi-axis displacement structure can quickly adjust the spatial position and posture of the labeling structure, so that the label can be attached to the part surface with the base coating at the set bonding angle and pressure. It is suitable for curved surfaces, inclined surfaces, or automotive parts with complex features, avoiding problems such as label lifting, offset, or poor adhesion caused by positional deviation.

[0024] Furthermore, the labeling mechanism also includes a vision recognition device, and both the vision recognition device and the second multi-axis displacement structure are signal-connected to the control mechanism; the control mechanism controls the second multi-axis displacement structure to move the labeling structure according to the workpiece position information recognized by the vision recognition device.

[0025] Beneficial effects: The vision recognition device identifies the positional information of the components and feeds this information back to the control mechanism. Based on the recognition results, the control mechanism automatically calculates the target position and motion trajectory required by the labeling mechanism, thereby driving the second multi-axis displacement structure to perform position compensation and attitude adjustment of the labeling structure. During the transportation process, even if there are slight offsets, rotations, or spacing changes in the components, the vision recognition device can detect them in real time and guide the labeling structure to dynamically follow, thus ensuring that the label is always accurately pasted in the preset base coating area, thereby ensuring the consistency of the labeling position.

[0026] Furthermore, a pressure-holding mechanism is also installed on the frame. The pressure-holding mechanism is located on the conveying path of the conveying mechanism and downstream of the labeling mechanism, so as to maintain pressure on the parts with labels attached.

[0027] Beneficial effects: By setting a pressure-holding mechanism downstream of the labeling mechanism, continuous and uniform pressure can be applied to the label, so that the adhesive of the adhesive label can fully wet the surface of the base coating, squeeze out residual air, and ensure that the label is tightly bonded to the base coating, preventing problems such as edge lifting and partial detachment of the label during subsequent handling, assembly or use.

[0030] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0031] Embodiments of the automatic labeling equipment for automotive parts provided by the present invention: like Figures 1 to 13 As shown, the automatic labeling equipment for automotive parts includes a frame 1 and a control mechanism. A conveying mechanism for conveying parts is installed on the frame 1. Along the conveying direction of the conveying mechanism, a spraying mechanism 5, a vision inspection mechanism 6, a baking mechanism 7, a labeling mechanism 8, and a pressure holding mechanism 9 are arranged in a straight line on the frame 1.

[0032] The control mechanism is connected to the conveying mechanism, the spraying mechanism 5, the vision inspection mechanism 6, the baking mechanism 7, and the labeling mechanism 8 by signal connection. It is used to control the conveying mechanism to transport the parts, and to control the spraying mechanism 5 to spray the primer layer on the parts in sequence, control the vision inspection mechanism 6 to detect whether the primer layer is qualified, control the baking mechanism 7 to heat the primer layer, and control the labeling mechanism 8 to stick the label onto the primer layer.

[0033] like Figure 1 and Figure 10 As shown, in this embodiment, the conveying mechanism is provided with a plurality of support platforms 10 for supporting components, and the plurality of support platforms 10 are spaced apart on the conveying mechanism.

[0034] like Figure 1 , Figure 10 and Figure 13 As shown, in this embodiment, the conveying mechanism includes a first conveying component 2, a conveying transfer component 4, and a second conveying component 3 arranged sequentially along its conveying direction. The first conveying component 2 and the second conveying component 3 are arranged in parallel, with opposite conveying directions. The conveying transfer component 4 facilitates the transfer of the carrier platform 10 between the first conveying component 2 and the second conveying component 3. The spraying mechanism 5, the visual inspection mechanism 6, the baking mechanism 7, the labeling mechanism 8, and the pressure holding mechanism 9 are all arranged sequentially on the frame 1 along the conveying direction of the second conveying component 3. All processing steps are completed on the second conveying component 3.

[0035] like Figure 4 and Figure 5As shown, in this embodiment, the first conveying assembly 2 includes a first drive motor 21, a first active synchronous pulley 22, a first driven synchronous pulley 23, a second driven synchronous pulley 24, a first driven roller 25, and a first synchronous belt 26. The first drive motor 21 is fixedly mounted on the frame 1. The first active synchronous pulley 22 is mounted on the output end of the first drive motor 21. The first driven synchronous pulleys 23, 24, and 25 are all rotatably mounted on the frame 1. The first synchronous belt 26 is arranged around the outside of the aforementioned pulleys. The first drive motor 21 drives the first active synchronous pulley 22 to rotate, thereby driving the first synchronous belt 26 to move. The toothed layer of the first synchronous belt 26 meshes with the first active synchronous pulley 22, 23, and 24 to ensure the running accuracy of the first synchronous belt 26 and prevent slippage. The back layer of the first synchronous belt 26 frictionally drives the first driven roller 25 to transmit power.

[0036] In this embodiment, the bottom of the support platform 10 engages with the first synchronous belt 26 for transmission, so that the support platform 10 can move synchronously with the first synchronous belt 26.

[0037] like Figure 7 and Figure 10 As shown, in this embodiment, a first slide rail 11 is installed on the frame 1. The first slide rail 11 is located inside the first synchronous belt 26, and the bottom surface of the support platform 10 is provided with a sliding groove that slides in cooperation with the first slide rail 11. While the support platform 10 moves with the first synchronous belt 26, it slides along the first slide rail 11, which constrains the movement direction of the support platform 10, preventing it from swaying left or right or twisting under the drive of the first synchronous belt 26, ensuring that the support platform 10 travels in a straight line along the conveying direction. Simultaneously, the weight of the support platform 10 and its components is transferred to the first slide rail 11, preventing the first synchronous belt 26 from bearing excessive load, thereby reducing wear and deformation of the first synchronous belt 26 and extending its service life.

[0038] like Figure 2 , Figure 9 , Figure 10 , Figure 12 and Figure 13As shown, in this embodiment, the structure of the second conveying assembly 3 is the same as that of the first conveying assembly 2. Specifically, the second conveying assembly 3 includes a second drive motor 31, a second driving synchronous pulley 32, a third driven synchronous pulley 33, a fourth driven synchronous pulley, a second driven roller 34, and a second synchronous belt 35. The second drive motor 31 is fixedly mounted on the frame 1, the second driving synchronous pulley 32 is mounted on the output end of the second drive motor 31, and the third driven synchronous pulley 33, the fourth driven synchronous pulley, and the second driven roller 34 are all rotatably mounted on the frame 1. The second synchronous belt 35 is arranged around the outside of the aforementioned pulleys. The second drive motor 31 drives the second driving synchronous pulley 32 to rotate, thereby driving the second synchronous belt 35 to move. The toothed layer of the second synchronous belt 35 meshes with the second driving synchronous pulley 32, the third driven synchronous pulley 33, and the fourth driven synchronous pulley to ensure the running accuracy of the second synchronous belt 35 and prevent slippage; the back layer of the second synchronous belt 35 frictionally drives the second driven roller 34 to transmit power.

[0039] In this embodiment, the bottom of the support platform 10 engages with the second synchronous belt 35 for transmission, so that the support platform 10 can move synchronously with the second synchronous belt 35.

[0040] like Figure 2 , Figure 8 , Figure 9 , Figure 10 and Figure 12 As shown, in this embodiment, a second slide rail 12 is installed on the frame 1. The second slide rail 12 is located inside the second synchronous belt 35, and it slides in cooperation with the groove on the bottom surface of the support platform 10. While the support platform 10 moves with the second synchronous belt 35, it slides along the second slide rail 12, which constrains the movement direction of the support platform 10, preventing it from swaying left or right or twisting under the drive of the second synchronous belt 35, ensuring that the support platform 10 travels in a straight line along the conveying direction. Simultaneously, the weight of the support platform 10 and its components is transferred to the second slide rail 12, preventing the second synchronous belt 35 from bearing excessive load, thereby reducing wear and deformation of the second synchronous belt 35 and extending its service life.

[0041] like Figure 10 and Figure 11 As shown, in this embodiment, the conveying and transfer assembly 4 includes a third slide rail 41 and a slider 42. The third slide rail 41 is mounted on the frame 1, and the slider 42 is slidably mounted on the third slide rail 41. The extension direction of the third slide rail 41 is perpendicular to the extension direction of the first slide rail 11 and the second slide rail 12. The slider 42 is provided with a fourth slide rail 421 that is consistent with the extension direction of the first slide rail 11 and the second slide rail 12. The fourth slide rail 421 is used to connect with the conveying end of the first slide rail 11 and the conveying beginning of the second slide rail 12. The sliding groove on the bottom surface of the support platform 10 is slidably engaged with the fourth slide rail 421.

[0042] In this embodiment, the frame 1 is also equipped with a slider 42 drive connected to the slider 42, a detector 13 located at the end of the first slide rail 11, and a detector 13 located at the beginning of the second slide rail 12. The detector 13 is signal-connected to the slider 42 drive and the control mechanism. When the detector 13 detects that the carrier platform 10 has passed the end of the first slide rail 11, it determines that the carrier platform 10 has been transported to the slider 42. After receiving this information, the control mechanism controls the slider 42 drive to drive the slider 42 to slide towards the beginning of the second slide rail 12. When the detector 13 located at the beginning of the second slide rail 12 detects the carrier platform 10, it determines that the carrier platform 10 has been transported to the second slide rail 12. After receiving this information, the control mechanism controls the slider 42 drive to drive the slider 42 to slide towards the end of the first slide rail 11. During the sliding process, the inner wall of the slide groove and the outer wall of the fourth slide rail 421 maintain a clearance fit, which restricts the degree of freedom of the support platform 10 relative to the fourth slide rail 421 in the direction perpendicular to the movement direction. The support platform 10 and the slider 42 do not have a degree of freedom of relative displacement in the direction perpendicular to the movement direction. Therefore, the support platform 10 can only follow the slider 42 to make rigid translations, and cannot sway or deflect relative to the slider 42, thereby ensuring that the support platform 10 is accurately transferred to the second slide rail 12.

[0043] like Figure 1 , Figure 2 and Figure 10 As shown, in this embodiment, the spraying mechanism 5 includes a first mounting frame 51, a first multi-axis displacement structure 52, and a spraying assembly. The first mounting frame 51 is fixedly mounted on the frame 1, and the first multi-axis displacement structure 52 is fixedly mounted on the first mounting frame 51 and located above the second conveying assembly 3. The spraying assembly is mounted at the end of the first multi-axis displacement structure 52. The first multi-axis displacement structure 52 is signal-connected to the control mechanism and can drive the spraying assembly to move in three-dimensional space, thereby uniformly coating the base coating onto the surface of the component to be labeled according to a preset trajectory. In this embodiment, the first multi-axis displacement mechanism is a three-axis slide; in other embodiments, the first multi-axis displacement mechanism can be a three-axis manipulator or a six-axis robot.

[0044] In this embodiment, the spraying assembly includes a spray gun 53, which is used to spray a primer onto the component.

[0045] like Figure 2As shown, in this embodiment, the vision inspection mechanism 6 is mounted on the frame 1 and located downstream of the spraying mechanism 5. It is signal-connected to the control mechanism and is used to acquire images of the surface of the parts after spraying, and transmit the image information to the control mechanism. The control mechanism analyzes the images using a built-in image processing algorithm to determine whether the spraying quality of the base coating meets the requirements. If the spraying is found to be unqualified, the subsequent mechanism is controlled not to process the parts, and the parts are directly transported to the unloading station. In this embodiment, the vision inspection mechanism 6 includes a second mounting frame 61 and a vision camera 62. The second mounting frame 61 is fixedly mounted on the frame 1, and the vision camera 62 is mounted on the second mounting frame 61 and located above the second conveying assembly 3. In other embodiments, the vision camera 62 can be replaced by a laser displacement sensor.

[0046] like Figure 2 , Figure 3 and Figure 10 As shown, in this embodiment, the baking mechanism 7 is mounted on the frame 1 and located downstream of the vision inspection mechanism 6. It includes a third mounting bracket 71 and a hot air generator. The third mounting bracket 71 is fixedly mounted on the frame 1, and the hot air generator is mounted on the third mounting bracket 71 and located above the second conveying assembly 3. The hot air generator is signal-connected to the control mechanism. When a qualified coated component passes through the baking mechanism 7, the hot air generator generates hot air to heat and cure the base coating on the surface of the component, allowing the base coating to reach a preset adhesion strength. In this embodiment, the hot air generator is a hot air blower 72; in other embodiments, the hot air generator can be a heater combining a resistance heating wire and a fan, a hot air device combining an infrared heating tube and a fan, etc.

[0047] like Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 10As shown, in this embodiment, the labeling mechanism 8 is mounted on the frame 1 and located downstream of the baking mechanism 7. It includes a fourth mounting frame 81, a labeling structure 82, a second multi-axis displacement structure 83, and a vision recognizer. The fourth mounting frame 81 is fixedly mounted on the frame 1, and the second multi-axis displacement structure 83 is fixedly mounted on the fourth mounting frame 81. The labeling structure 82 is mounted at the end of the second multi-axis displacement structure 83 and is used to pick up and affix adhesive labels. The vision recognizer is mounted beside the second multi-axis displacement structure 83, and both it and the second multi-axis displacement structure 83 are signal-connected to the control mechanism. The vision recognizer is used to acquire images of the baked parts, identify the position information of the parts, and transmit it to the control mechanism. The control mechanism controls the second multi-axis displacement structure 83 to move the labeling structure 82 according to the position information, accurately affixing the label to the base coating of the parts. In this embodiment, the second multi-axis displacement mechanism is a three-axis slide; in other embodiments, the second multi-axis displacement mechanism can be a three-axis manipulator or a six-axis robot. The labeling structure 82 can be a roller-type labeling head or a vacuum suction-type labeling head, which are existing technologies and will not be described in detail here.

[0048] like Figure 1 , Figure 3 , Figure 9 and Figure 13 As shown, in this embodiment, the pressure-holding mechanism 9 is mounted on the frame 1 and located downstream of the labeling mechanism 8, and is signal-connected to the control mechanism. When a component with a label passes through the pressure-holding mechanism 9, the pressure-holding mechanism 9 applies a preset pressure to the label and holds it for a certain period of time, so that the label and the base coating are fully adhered, improving the adhesion of the label. In this embodiment, the pressure-holding mechanism 9 includes a fifth mounting frame 91, a pressing drive structure 92, and a pressing component 93. The fifth mounting frame 91 is mounted on the frame 1, the pressing drive structure 92 is mounted on the fifth mounting frame 91, and the pressing component 93 is mounted on the output end of the pressing drive structure 92, used to press the label down under the drive of the pressing drive structure 92 to achieve pressure holding; the pressing drive structure 92 can be a cylinder or an electric cylinder, etc.

[0049] It should be noted that, in this embodiment, a transfer component is provided between the loading position of the first conveying component 2 and the unloading position of the second conveying component 3. The transfer component is used to place automotive parts on the empty support platform 10 at the unloading position and transfer the support platform 10 containing the automotive parts to the loading position. The transfer component can be an industrial robot or an automated device such as a linear module equipped with grippers. The linear module drives the grippers to grasp the support platform 10 at the unloading position and then move it horizontally to the loading position to release it. In other embodiments, the support platform 10 can also be manually transferred between the loading and unloading positions.

[0050] The working principle of the automatic labeling equipment for automotive parts provided by this invention is as follows: First, the carrier platform 10, on which the parts are fixed, is placed in the loading position. The control mechanism controls the first conveying component 2 to operate, conveying the carrier platform 10 to the conveying transfer component 4. The conveying transfer component 4 transfers the carrier platform 10 to the second conveying component 3. The second conveying component 3 drives the carrier platform 10 to pass sequentially through the spraying mechanism 5, the vision inspection mechanism 6, the baking mechanism 7, the labeling mechanism 8, and the pressure holding mechanism 9. At the spraying station, the first multi-axis displacement structure 52 drives the spraying component to coat the surface of the parts with a base coating according to a preset trajectory. At the inspection station, the vision inspection mechanism 6 inspects the spraying quality of the base coating. At the baking station, the hot air generator heats and cures the base coating. At the labeling station, the vision recognition device identifies the position of the parts, and the control mechanism controls the second multi-axis displacement structure 83 to drive the labeling structure 82 to complete the label application. At the pressure holding station, the pressure driving structure 92 drives the pressure component 93 to press down, performing pressure holding treatment on the label. After processing is completed, the carrier platform 10 moves to the unloading position with the second conveying component 3 to unload the labeled parts. The transfer component places the parts on the empty carrier platform 10 at the unloading position and transfers the carrier platform 10 with the parts to the loading position to prepare for the next round of processing.
