Description

Technical Field

[0001] This utility model relates to the field of production and processing equipment technology, and in particular to a coating equipment. Background Technology

[0002] Coating is a technical process of applying a coating to the surface of a product. It is often used for product protection. The quality of the surface coating of some components directly affects the overall quality and appearance of the product.

[0003] However, traditional coating equipment typically uses fixed supports or structures to hold the workpiece. When the workpiece to be coated is uneven due to transport errors or surface irregularities, this support method makes it difficult for the coating device to coat complex curved or warped surfaces, easily leading to problems such as uneven coating thickness, edge overflow, or localized missed coating. In addition, traditional equipment often relies on manual adjustments to the workpiece position or manual compensation of the workpiece height, which is not only inefficient but also reduces coating quality due to human error. Utility Model Content

[0004] The purpose of this invention is to provide a coating device that solves the problem of low efficiency and poor coating quality caused by uneven workpieces during coating in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a coating device, comprising:

[0007] The rack is used to hold the workpiece;

[0008] A coating apparatus is used to coat workpieces.

[0009] A lifting device is mounted on a machine frame. The lifting device includes a lifting part that moves up and down along the machine frame. The lifting part is used to contact one end of the workpiece and adjust the height of one end of the workpiece.

[0010] Optionally, in the above-mentioned coating equipment, the frame includes:

[0011] The lower frame is used to place the workpiece.

[0012] The upper frame has a portion disposed above the lower frame, and a lifting device is disposed on the lower frame, the lifting device including a lifting part disposed to move up and down along the lower frame.

[0014] The support component is connected to the lower frame and moves up and down along the lower frame. The support component is used to support and contact one end of the workpiece.

[0015] A drive component is located on the lower frame. The drive end of the drive component is connected to the support component and is used to drive the support component to move up and down along the lower frame.

[0016] Optionally, in the above-mentioned coating equipment, there are two support components, which are arranged in parallel on the lower frame. The two support components are controlled by independent drive components to adjust the two ends of the workpiece to different heights.

[0017] Optionally, in the above-described coating equipment, the coating apparatus includes:

[0018] The robotic arm is fixedly connected to the frame.

[0019] The coating component is fixed on the robotic arm and is used to coat the workpiece.

[0020] Optionally, in the above-described coating equipment, the coating equipment further includes:

[0021] A first and a second bracket are arranged in parallel to each other and are connected to the lower frame;

[0022] The first conveyor belt and the second conveyor belt are respectively mounted on the first support and the second support, and are used to drive the workpiece to move;

[0023] A drive motor is mounted on the lower frame and is connected to the first and second transmission belts for driving the first and second transmission belts to rotate around the first and second supports respectively.

[0024] Optionally, in the above-described coating equipment, the coating equipment further includes:

[0025] The first lead screw is rotatably mounted on the lower frame, and the first support is movably mounted on the lower frame and has a first screw hole, which is connected to the first lead screw. The first lead screw is used to adjust the position of the first support.

[0030] Compared with existing technologies, the coating equipment provided by this utility model uses a lifting device that moves up and down along the frame to contact one end of the workpiece. When the workpiece is tilted due to uneven surface or transmission errors, the lifting device can independently adjust the height of one end of the workpiece. Simultaneously, combined with the movement trajectory of the coating device along the workpiece surface, it can compensate for the workpiece's height deviation in real time during the coating process, ensuring that the workpiece remains horizontal or parallel to the moving plane of the coating device throughout the coating process. This allows the coating component to apply coating along the same horizontal plane on the workpiece surface. This design, through the dynamic leveling function of the lifting device, solves the problems of uneven coating thickness and edge overflow caused by uneven workpiece surfaces or placement errors in traditional fixed support structures. Furthermore, the synergistic effect of the lifting device and the drive component replaces the manual repeated adjustment of the workpiece height, improving coating efficiency and avoiding interference from human error in coating quality, thus enhancing the overall coating quality.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] Please see Figure 1 and Figure 4 This utility model provides a coating device, including a frame 1, a coating device 2, and a lifting device 3; wherein, the frame 1 is used to place a workpiece 10; the coating device 2 is used to coat the workpiece 10; the lifting device 3 is disposed on the frame 1, and the lifting device 3 includes a lifting part that moves up and down along the frame 1, the lifting part being used to contact one end of the workpiece 10 and adjust the height of one end of the workpiece 10.

[0046] In specific implementation: The lifting device 3 contacts one end of the workpiece 10 via a lifting section that moves up and down along the frame 1. When the workpiece 10 is tilted due to uneven surface or transmission error, the lifting section can independently adjust the height of one end of the workpiece 10. Simultaneously, combined with the movement trajectory of the coating device 2 along the surface of the workpiece 10, it can compensate for the height deviation of the workpiece 10 in real time during the coating process, ensuring that the workpiece 10 remains horizontal or parallel to the moving plane of the coating device 2 throughout the coating process. The coating component 220 can apply coating along the surface of the workpiece 10 on the same horizontal plane. This configuration, through the dynamic leveling function of the lifting device 3, solves the problems of uneven coating thickness and edge overflow caused by uneven surface or placement error of the workpiece 10 in traditional fixed support structures. Furthermore, the synergistic effect of the lifting section and the drive component replaces the manual repeated adjustment of the workpiece 10 height, improving coating efficiency and avoiding interference from human error on coating quality, thus enhancing coating quality.

[0047] In some embodiments, the lifting device 3 is fixed to the two sides of the lower frame 120 via a mounting base. The lifting part moves vertically up and down along the lower frame 120 via a linear guide rail or guide groove. Its top is provided with a flexible contact pad or adjustable gripper for contacting the end of the workpiece 10 and applying a lifting force. In specific implementations, when the coating plane tilts due to warping or uneven thickness of the workpiece 10, the lifting part can move vertically along the guide rail, lifting one end of the workpiece 10 with the reference height of the other end via the contact component at the top, thereby ensuring that the coating device 2 performs the coating action on a horizontal or preset angle plane. The local height adjustment function of the lifting part solves the problem of uneven coating thickness caused by errors in the workpiece 10 itself or transmission errors in traditional equipment. Simultaneously, the lifting device 3 is independently set outside the transmission path, avoiding interference with the movement of the conveyor belt or the coating device 2, thus improving the safety of equipment operation.

[0048] As one possible implementation, please refer to Figure 1 The frame 1 includes a lower frame 120 and an upper frame 110; wherein, the lower frame 120 is used to place the workpiece 10; the upper frame 110 has a portion disposed above the lower frame 120, and the lifting device 3 is disposed on the lower frame 120, the lifting device 3 including a lifting part disposed to move up and down along the lower frame 120.

[0049] Specifically, the frame 1 includes a lower frame 120 and an upper frame 110. The lower frame 120 is used to place the workpiece 10, and the upper frame 110 is vertically connected to the lower frame 120 via a support column structure or frame structure, or the upper frame 110 is fitted around the lower frame 120 and has a portion located above the lower frame 120. In specific implementation, the lower frame 120 serves as the basic platform for carrying and transporting the workpiece 10, while the upper frame 110 provides an unobstructed operating space for the coating operation through its suspended layout. After the workpiece 10 is placed on the lower frame 120, and after the lifting device 3 adjusts the unevenness of the workpiece 10, the coating device 2 moves to the surface of the workpiece 10 to perform coating. With this split design, the lower frame 120 and the upper frame 110 work together, which not only ensures the stability of the workpiece 10 transmission, but also avoids the interference of mechanical vibration on the coating quality during the coating process. This solves the problem of low coating accuracy caused by spatial coupling in traditional integrated frame 1. In addition, the separation of the upper and lower frames 120 facilitates equipment maintenance and component replacement, reducing downtime maintenance costs.

[0050] As one possible implementation, please refer to Figure 5The lifting device 3 includes a support component and a drive component. The support component is connected to the lower frame 120 and moves up and down along the lower frame 120. The support component is used to contact one end of the workpiece 10 and adjust the height of one end of the workpiece 10. The drive component is disposed on the lower frame 120 and the drive end of the drive component is connected to the support component. It is used to drive the support component to move up and down along the lower frame 120.

[0051] Specifically, please refer to Figure 6 and Figure 7 The support component is slidably connected to the lower frame 120 via a linear guide rail. The drive component can be a servo motor or a pneumatic cylinder, with its fixed end installed at the bottom of the lower frame 120 and its drive end connected to the bottom of the support component via a connecting rod. In specific implementation, the initial position of the support component is lower than the bearing plane of the first conveyor belt 410 and the second conveyor belt 510 to avoid interfering with the transmission of the workpiece 10. After the workpiece 10 moves to the coating station via the first conveyor belt 410 and the second conveyor belt 510, the servo motor or pneumatic cylinder is driven to move, pushing the support component to rise vertically along the guide rail until it contacts the end of the workpiece 10, and applying a supporting force to locally lift the workpiece 10 to a horizontal state. Then, the coating device 2 performs a coating action on the surface of the stably supported workpiece 10. After coating is completed, the support component returns to its low position, and the coated workpiece 10 is placed on the first conveyor belt 410 and the second conveyor belt 510. The conveyor belts continue to transfer the workpiece 10 to the next process. By coordinating the lifting device 3 with the conveyor belt, the problem of coating path deviation caused by workpiece 10 shaking or flexible deformation when the traditional conveyor belt is running continuously is solved. Compared with simply relying on the conveyor belt for support, the rigid support of the support component significantly improves the stability of workpiece 10 during the coating process, which is especially suitable for precision coating of thin-walled parts or easily deformable workpiece 10. At the same time, the lifting device 3 only intervenes to provide support during the coating stage, avoiding energy consumption and wear caused by frequent start and stop of the conveyor belt.

[0052] Further, please refer to Figure 5 There are two support components, which are arranged in parallel on the lower frame 120. The two support components are controlled by independent drive components to adjust the two ends of the workpiece 10 to different heights.

[0053] In practice, after workpiece 10 is transported to the coating station via the transmission device, the image acquisition device first scans the surface of workpiece 10 to identify height deviations or warping at both ends. The controller sends commands to the drive components on both sides based on the deviation data, driving the two support components to move up and down along the guide rails to below both ends of workpiece 10. The lifting height of the support plates is independently adjusted, with one end raised higher and the other lower, until workpiece 10 is leveled. Subsequently, the coating device 2 performs the coating action on the flat surface of workpiece 10 according to the planned path, avoiding uneven coating thickness caused by the tilt of workpiece 10. The independent leveling design of the dual support components solves the problem that traditional single lifting mechanisms cannot adapt to differences in workpiece 10 thickness or deformation. Especially for large-sized flat workpieces 10, it can accurately compensate for local unevenness, ensuring the consistency of the coating surface. At the same time, the independent drive design avoids displacement or damage to workpiece 10 due to uneven force at both ends during the leveling process.

[0054] As one possible implementation, please refer to Figure 2 The coating device 2 includes a robotic arm 210 and a coating component 220; wherein, the robotic arm 210 is fixedly connected to the frame 1 and is used to move along the area to be coated of the workpiece 10; the coating component 220 is fixed on the robotic arm 210 and is used to coat the workpiece 10.

[0055] Specifically, the robotic arm 210 is fixed to the frame 1 via a mounting base, and the coating component 220 is fixedly connected to the end of the robotic arm 210. The robotic arm 210 has a multi-axis linkage structure, ensuring that it can move in three-dimensional space along the area to be coated on the workpiece 10. In practice, the robotic arm 210 drives the coating component 220 to move to the target position based on the coating path planned by the controller. Under the control of the robotic arm 210, the coating component 220 coats the area to be coated at a preset speed. At the same time, the image detection device captures the coating status in real time and feeds it back to the controller. The controller dynamically adjusts the moving speed of the robotic arm 210 or the output of the coating component 220 and corrects the coating trajectory. By combining the three-dimensionally movable robotic arm 210 and the coating component 220, the problem that traditional fixed coating mechanisms cannot adapt to irregularly shaped workpieces 10 or complex curved surfaces is solved. At the same time, the multi-degree-of-freedom motion characteristics of the robotic arm 210 ensure the continuous operation of the coating path and avoid coating defects caused by manual coating or repeated mechanical coating.

[0056] As one possible implementation, please refer to Figure 5The coating equipment also includes a first support 4 and a second support 5 arranged in parallel with each other, a first conveyor belt 410 and a second conveyor belt 510, and a drive motor; wherein, the first support 4 and the second support 5 are connected to the lower frame 120; the first conveyor belt 410 and the second conveyor belt 510 are respectively arranged on the first support 4 and the second support 5, and are used to drive the workpiece 10 to move; the drive motor is drivenly connected to the first conveyor belt 410 and the second conveyor belt 510, and is used to drive the first conveyor belt 410 and the second conveyor belt 510 to transmit power around the first support 4 and the second support 5, respectively.

[0057] Specifically, the first support 4 and the second support 5 are mounted on both sides of the lower frame 120 via slide rails or guide grooves. The first conveyor belt 410 and the second conveyor belt 510 are respectively fitted onto the first support 4 and the second support 5 to form a closed-loop transmission structure. The drive motor drives the first conveyor belt 410 and the second conveyor belt 510 to rotate synchronously. In practice, the workpiece 10 is placed on the first conveyor belt 410 and the second conveyor belt 510. The drive motor drives the first conveyor belt 410 and the second conveyor belt 510 to move, causing the workpiece 10 to move smoothly in a straight line to the working area below the upper frame 110. After coating is completed, the workpiece 10 can also be moved to the next station. This design distributes the weight of the workpiece 10 through the double-belt support structure, improving the transmission stability of long or large workpieces 10.

[0058] As one possible implementation, please refer to Figure 5 The coating equipment also includes a first lead screw 6 and a second lead screw 7. The first lead screw 6 is rotatably mounted on the lower frame 120. The first support 4 is movably mounted on the lower frame 120 and has a first screw hole, which is connected to the first lead screw 6. The first lead screw 6 is used to adjust the position of the first support 4. The second lead screw 7 is rotatably mounted on the lower frame 120. The second support 5 is movably mounted on the lower frame 120 and has a second screw hole, which is connected to the second lead screw 7. The second lead screw 7 is used to adjust the position of the second support 5.

[0059] Specifically, the first lead screw 6 and the second lead screw 7 are horizontally mounted on both sides of the bottom of the lower frame 120 through bearing seats. The first bracket 4 and the second bracket 5 are threadedly engaged with the first lead screw 6 and the second lead screw 7 through the first screw hole and the second screw hole on their bottom, respectively, to achieve lateral linear movement. It should be noted that the lateral linear movement direction of the first bracket 4 and the second bracket 5 is the interval direction between the first bracket 4 and the second bracket 5. The ends of the first lead screw 6 and the second lead screw 7 are respectively connected to handwheels or servo motors to drive the lead screws to rotate forward and backward to adjust the lateral position of the first bracket 4 and the second bracket 5. In practical implementation, when the bottom surface of workpiece 10 has a protruding structure or needs to be adapted to workpieces 10 of different sizes, the first lead screw 6 and the second lead screw 7 can be rotated synchronously or independently by rotating the handwheel or driving the servo motor. This causes the first support 4 or the second support 5 to move laterally along the first lead screw 6 or the second lead screw 7, thereby adjusting the distance between the first transmission belt 410 and the second transmission belt 510. This ensures that the first transmission belt 410 or the second transmission belt 510 avoids the protruding area of ​​workpiece 10 or closely fits the edge of workpiece 10, avoiding offset or stagnation caused by friction or interference during transmission. Through the threaded transmission structure between the lead screw and the support, high-precision adjustment of the transmission belt distance is achieved, solving the problem of frequent fixture changes required by traditional fixed-distance transmission devices due to differences in the size or structure of workpiece 10, and improving the adaptability of the equipment to different process requirements. At the same time, the self-locking characteristic of the lead screw transmission ensures the stability of the support position, preventing transmission belt displacement caused by vibration during equipment operation.

[0060] As one possible implementation, the coating equipment also includes a monitoring device 8, which is mounted on the frame 1 and is used to acquire images of the area to be coated on the workpiece 10.

[0061] The monitoring device 8 is fixedly mounted on the upper part of the frame 1 via a bracket, located to the side or rear of the coating device 2, with its lens facing the surface of the workpiece 10 to be coated. During the coating process, the monitoring device 8 records the real-time status of the coating area through high-frequency imaging, capturing the physical characteristics of the coating trajectory, coating thickness, and boundary contour, and transmits the acquired images to an external display or storage device. Through the image recording function of the monitoring device 8, operators can check the coating quality after coating is completed, thus replacing traditional manual visual inspection. This setup, through the image acquisition function of the monitoring device 8, solves the problem of traditional equipment lacking visual recording of the coating process, while reducing manual intervention and improving quality inspection efficiency.

[0062] As one possible implementation, the monitoring device 8 includes multiple high-frequency cameras, which are fixed at the corners of the frame 1 for acquiring images of the workpiece 10 from multiple angles.

[0063] Specifically, multiple high-frequency cameras are fixed to at least the corner positions of the upper frame 110 via mounting brackets, with their lenses facing the workpiece 10 on the lower frame 120. The coverage areas of adjacent high-frequency cameras partially overlap to cover the entire area of ​​the workpiece 10 to be coated. In practice, the multiple high-frequency cameras form multi-angle video coverage based on the corner layout of the upper frame 110. When the workpiece 10 is placed on the lower frame 120, each high-frequency camera simultaneously captures images of the surface of the workpiece 10 and transmits them to a viewing terminal for real-time monitoring of the coating quality and progress of the workpiece 10. Through the collaborative work of multiple high-frequency cameras, the blind spots of a single perspective are eliminated, and the visual deviation problem caused by the surface undulations or reflections of the workpiece 10 caused by traditional single cameras is solved. At the same time, the high-frequency shooting characteristics of the high-frequency cameras ensure the ability to capture images of the moving workpiece 10, avoiding trajectory deviation caused by the displacement of the workpiece 10 during the coating process, and significantly improving the accuracy of the coating path.

[0064] It should be noted that the placement of multiple high-frequency cameras is not limited to the corners of the upper frame 110. When the upper frame 110 is a rectangular frame structure, the placement of multiple high-frequency cameras can include the corners and edges of the frame to ensure full coverage of the field of view without blind spots.

[0065] As one possible implementation, the coating equipment also includes a surface light source 9, which is mounted on the frame 1 to provide uniform illumination to the monitoring device 8.

[0066] Specifically, the surface light source 9 is horizontally fixed to the lower part of the frame 1 via a mounting bracket, positioned around the workpiece 10 below it, forming a uniform light field covering the area of ​​the workpiece 10 to be coated. When the workpiece 10 is placed on the frame 1, the surface light source 9 continuously provides stable illumination, ensuring that the monitoring device 8 clearly captures the contours of the workpiece 10 surface and the details of the coated area. This coordinated vertical arrangement of the surface light source 9 and the monitoring device 8 solves the problems of uneven image brightness and blurred details caused by traditional equipment relying on ambient light or local point light sources, improving the visual positioning accuracy of the coated area and the consistency of coating quality.

[0067] In some embodiments, the surface light source 9 can be designed as a multi-area independently controlled LED array, with multiple LEDs set on the upper frame 110, which can locally enhance the lighting intensity according to the shape of the workpiece 10; a protective cover can also be added to prevent coating material from splashing and contaminating the surface of the light source, thus extending its service life.
