Description

Technical Field

[0001] This application relates to the field of precast building component production equipment technology, and in particular to an all-around oiling device and method for prefabricated component molds. Background Technology

[0002] In the production process of prefabricated building components such as composite slabs, wall panels, beams and columns, in order to facilitate the smooth demolding of the hardened components, the inner surface of the mold usually needs to be pre-coated with a release agent, also known as oiling.

[0003] Currently, the main methods for coating molds include manual brushing, compressed air spraying, and electrostatic spraying. Manual brushing is not only inefficient, but also prone to missing or unevenly coating complex areas such as corners, recesses, and edges, leading to chipped corners or surface damage during demolding. Compressed air spraying, while more efficient, suffers from severe overspraying, with large amounts of oil mist dispersing into the air, wasting release agent and polluting the workshop environment, adhering to equipment and floors. Electrostatic spraying, on the other hand, requires high-quality mold materials and still lacks sufficient coverage for deep cavities and hard-to-reach areas.

[0004] Therefore, there is an urgent need for an oiling device that can both cover the mold surface and reduce waste. Summary of the Invention

[0005] To help cover the mold surface and prevent missed coating, and to effectively recover the dispersed oil mist and reduce waste to a certain extent, this application provides an all-around oiling device and method for prefabricated component molds.

[0022] The following combination Figures 1-4 This application will be described in further detail.

[0023] This application discloses an all-around oiling device for prefabricated component molds. The all-around oiling device is used in the production process of prefabricated building components such as composite slabs, wall panels, beams, and columns to coat the inner surface of the mold with oil, i.e., to apply a release agent. (Refer to...) Figure 1 , Figure 2 and Figure 3 The all-around oiling device for prefabricated component molds includes a walking mechanism 1, a mounting platform 2, an oiling mechanism 3, an oil mist recovery mechanism 4, a vision inspection mechanism, and a control mechanism.

[0024] Reference Figure 1 The traveling mechanism 1 serves as the main mobile support for the entire oiling device. It is used to span above the mold conveyor line. During use, the mold is conveyed to a preset position below the traveling mechanism 1 via the mold conveyor line for oiling. After oiling is completed, the mold conveyor line conveys the oiled mold to the next process and simultaneously conveys the mold to be oiled to the area below the traveling mechanism 1, thereby achieving continuous oiling operation.

[0025] Reference Figure 2 and Figure 3 The mounting platform 2 is mounted on the traveling mechanism 1, which moves the mounting platform 2 along a preset path. The oiling mechanism 3 is mounted on the mounting platform 2 and is used to apply oil to the mold below. The oil mist recovery mechanism 4 is mounted on the mounting platform 2 and is used to recover the oil mist that dissipates during the oiling process, preventing oil mist from polluting the workshop environment. The vision inspection mechanism is used to inspect the surface of the mold after oiling and identify areas where the oil has been missed.

[0026] Reference Figure 2 and Figure 3 To improve the automation and intelligence of the entire oiling operation, the walking mechanism 1, the oiling mechanism 3, the oil mist recovery mechanism 4, and the vision inspection mechanism are all connected to the control mechanism. Specifically, the control mechanism preferably uses an industrial PLC system or an industrial computer system. The control mechanism has a built-in control program that can automatically match the corresponding oiling path and oiling parameters according to the mold model and coordinate the collaborative actions of each mechanism.

[0027] During operation, molds for prefabricated building components such as composite slabs, wall panels, or beams and columns are transported to a preset position below the all-around oiling device via a mold conveyor line and locked. The control mechanism obtains the mold model and location information through image recognition or barcode scanning, loads the corresponding oiling path and oiling parameters, and then the traveling mechanism 1 drives the mounting platform 2 and the oiling mechanism 3 on the mounting platform 2 to apply oil along the predetermined oiling path. During the oiling process, the oil mist recovery mechanism 4 recovers the scattered oil mist, and the visual inspection mechanism detects the surface of the mold after oiling in real time and identifies the missed areas. The control mechanism records the coordinates of the missed areas. After the oiling is completed, the traveling mechanism 1 drives the mounting platform 2 and the oiling mechanism 3 to move and re-coat according to the coordinates of the missed areas. After the re-coating is completed, the traveling mechanism 1 resets, the mold conveyor line releases the oiled mold and drives the mold to the next process. This application, through the combination of formal oiling and re-coating, helps to cover the mold surface and reduces the likelihood of missed areas. At the same time, the setting of the oil mist recovery mechanism 4 can effectively recover the scattered oil mist, reducing waste to a certain extent.

[0028] Reference Figure 1 and Figure 2 To facilitate the movement of the oiling mechanism 3 mounted on the gimbal 2 along a preset path, the traveling mechanism 1 includes a base 101, a bracket 102, a sliding platform 103, a lifting platform 104, a first driving component 105, a second driving component 106, and a third driving component 107. The base 101 serves as the fixed support foundation for the entire traveling mechanism 1 and can be fixedly installed on the workshop floor. Specifically, two bases 101 are provided, each fixedly installed on opposite sides of the mold conveyor line on the workshop floor. The bracket 102 is slidably mounted on the base 101, spanning above the mold conveyor line. In this embodiment, the bracket 102 is a gantry frame; in other embodiments, the bracket 102 can also be designed as a cantilever frame. The sliding direction of the bracket 102 is parallel to the conveying direction of the mold conveyor line, and the sliding direction of the bracket 102 is defined as the X direction. Specifically, a linear guide rail is fixedly installed on the base 101 along the X direction, and the two ends of the bracket 102 are slidably engaged with the linear guide rail through sliders, so that the bracket 102 can reciprocate along the length of the mold conveyor line.

[0029] Reference Figure 1 and Figure 2 The sliding table 103 is slidably mounted on the crossbeam of the support 102. The sliding table 103 is located above the mold conveyor line, and the sliding direction of the sliding table 103 is perpendicular to the sliding direction of the support 102. The sliding direction of the sliding table 103 is defined as the Y direction. Specifically, a linear guide rail is provided on the crossbeam of the support 102 along the Y direction. The sliding table 103 slides with the linear guide rail through a slider, enabling the sliding table 103 to reciprocate in a direction perpendicular to the mold conveyor line.

[0030] Reference Figure 1 and Figure 2 The lifting platform 104 is slidably mounted on the sliding platform 103 in a vertical direction. The sliding direction of the lifting platform 104 is perpendicular to the sliding direction of the sliding platform 103, and the sliding direction of the lifting platform 104 is defined as the Z direction. The gimbal 2 is mounted at the bottom end of the lifting platform 104. Specifically, a vertical guide rail is provided on the sliding platform 103, and the lifting platform 104 slides up and down along the vertical guide rail.

[0031] Reference Figure 1 and Figure 2 The first driving component 105 is disposed on the base 101 and is used to drive the bracket 102 to slide in the X direction; the second driving component 106 is disposed on the bracket 102 and is used to drive the sliding table 103 to slide in the Y direction; the third driving component 107 is disposed on the sliding table 103 and is used to drive the lifting table 104 to slide in the Z direction; the first driving component 105, the second driving component 106 and the third driving component 107 are all communicatively connected to the control mechanism and are uniformly coordinated and controlled by the control mechanism.

[0032] Reference Figure 2 Furthermore, the first driving component 105, the second driving component 106, and the third driving component 107 can all be driven by a servo motor in conjunction with a ball screw, or by a servo motor in conjunction with a rack and pinion, or by a linear motor, rodless cylinder, or other driving components directly. In this embodiment, the first driving component 105, the second driving component 106, and the third driving component 107 are all driven by a servo motor in conjunction with a ball screw. Specifically, the servo motor of the first driving component 105 is fixedly mounted on the base 101, its ball screw is rotatably mounted on the base 101, and the lower end of the bracket 102 is connected to the moving nut of the corresponding ball screw. The servo motor of the second drive component 106 is fixedly mounted on the crossbeam of the bracket 102, and its ball screw is rotatably mounted on the bracket 102. The sliding table 103 is connected to the moving nut of the corresponding ball screw. Similarly, the servo motor of the third drive component 107 is fixedly mounted on the sliding table 103, and its ball screw is rotatably mounted on the sliding table 103. The lifting table 104 is connected to the moving nut of the corresponding ball screw. Specifically, the first drive component 105, the second drive component 106, and the third drive component 107 are all equipped with encoders to provide real-time position information to the control mechanism, which helps to achieve closed-loop control.

[0033] During operation, the coordinated operation of the first driving component 105, the second driving component 106 and the third driving component 107 can drive the mounting gimbal 2 to move independently in the X, Y and Z directions, thereby enabling the walking mechanism 1 to drive the oiling mechanism 3 to any position above the mold, which helps to achieve comprehensive oiling coverage for molds of different sizes and shapes.

[0034] Reference Figure 2 and Figure 3 The mounting gimbal 2 has a circular cross-section and is rotatably mounted on the lifting platform 104 of the traveling mechanism 1 along a vertical axis. The lifting platform 104 is equipped with a drive source 5 for rotating the mounting gimbal 2, and the drive source 5 is communicatively connected to the control mechanism. Specifically, the bottom of the mounting gimbal 2 is rotatably connected to the lifting platform 104 via a slewing bearing 12, wherein the mounting gimbal 2 is fixed to the outer ring of the slewing bearing 12, and the lifting platform 104 is fixed to the inner ring of the slewing bearing 12.

[0035] Reference Figure 2 and Figure 3 To facilitate the rotation of the mounting gimbal 2, the drive source 5 includes a geared motor 51, a transmission gear 52, and a transmission gear ring 53. The geared motor 51 is fixedly mounted on the lifting platform 104. The transmission gear 52 is coaxially fixed with the output shaft of the geared motor 51. The transmission gear ring 53 is coaxially connected to the mounting gimbal 2, and the transmission gear 52 meshes with the transmission gear ring 53. The geared motor 51 is communicatively connected to the control mechanism. In other embodiments, the mounting gimbal 2 can also be rotatably connected to the lifting platform 104 via a rotating shaft. The drive source 5 uses a geared servo motor or a geared stepper motor, directly connecting the rotating shaft of the mounting gimbal 2 to the output shaft of the drive source 5, which also achieves the rotation of the mounting gimbal 2.

[0036] When in operation, the geared motor 51 is started, which drives the transmission gear 52 to rotate. The transmission gear 52 drives the transmission gear ring 53 and the mounting gimbal 2 to rotate, so that the oiling mechanism 3 can adjust the oiling direction by rotating the mounting gimbal 2. This helps to apply oil to the inside corners, corner areas and irregular areas of the mold, and improves the flexibility and coverage of the oiling.

[0037] Reference Figure 2 and Figure 3 To facilitate oiling the inner surface of the mold, the oiling mechanism 3 includes a nozzle 31, a metering pump 32, and an adjustment component 33. The nozzle 31 is movably disposed below the mounting gimbal 2. Multiple nozzles 31 are provided on the mounting gimbal 2. In this embodiment, the multiple nozzles 31 on the mounting gimbal 2 are spaced apart along the circumferential direction of the center of the mounting gimbal 2. In other embodiments, the multiple nozzles 31 may also be arranged at radial intervals along the mounting gimbal 2.

[0038] Reference Figure 2 and Figure 3Furthermore, each nozzle 31 is connected to an external oil supply device via an oil supply hose 13. A control valve is installed on the oil supply hose 13 of each nozzle 31. Specifically, the external oil supply device can be a structure consisting of an oil storage tank and an oil supply pump, delivering the release agent to each nozzle 31 through the oil supply hose 13. The capacity of the oil storage tank can be configured according to the needs of the production line. A filter can be installed on the oil supply hose 13 to remove impurities from the release agent and prevent clogging of the nozzles 31. In this embodiment, the nozzles 31 are fan-shaped atomizing nozzles, which helps to improve the uniformity of oil application.

[0039] Reference Figure 2 and Figure 3 Each nozzle 31 is paired with a metering pump 32, and each nozzle 31 is connected to an external oil supply device via a corresponding metering pump 32. Specifically, the metering pump 32 is installed on the oil supply hose 13 of the corresponding nozzle 31. The metering pump 32 controls the flow rate of the corresponding nozzle 31, helping to reduce waste caused by excessive oil or uneven coating caused by insufficient oil. The metering pump 32 is preferably a miniature peristaltic pump, gear pump, or plunger pump. The control valves on both the metering pump 32 and the oil supply hose 13 are communicatively connected to a control mechanism. The flow control signal of the metering pump 32 is issued by the control mechanism, which helps to achieve automated flow regulation. In this embodiment, the flow control range of each nozzle 31 is 0.1 ml / s to 5 ml / s. This flow range covers various working conditions, from fine touch-up coating to large-area rapid oiling. When applying oil to large, flat areas, the flow rate of nozzle 31 can be set to 3ml / s-5ml / s to improve oiling efficiency. When applying oil or touching up fine areas such as corners and edges, the flow rate can be set to 0.1ml / s-3ml / s to ensure oiling accuracy and uniformity. The metering pump 32 allows for stepless adjustment within the above flow rate range, and the control mechanism dynamically adjusts the flow rate of each nozzle 31 according to the needs of different sections along the oiling path.

[0040] Reference Figure 2 and Figure 3 The adjustment component 33 is mounted on the mounting platform 2. Each adjustment component 33 corresponds to one nozzle 31 and is used to adjust the angle of the corresponding nozzle 31. The adjustment component 33 is communicatively connected to the control mechanism, which adjusts the spray angle of each nozzle 31 according to the oiling path and mold shape.

[0041] During operation, the angle of the corresponding nozzle 31 can be adjusted by adjusting component 33, so that oil can be applied to the bottom plane, side walls and inside corners of the rectangular box mold.

[0042] Reference Figure 2 and Figure 3To facilitate adjustment of the nozzle 31 angle, the adjustment assembly 33 includes an adjustment body 331 and a rotation drive 332. The adjustment body 331 corresponds one-to-one with the nozzle 31. The adjustment body 331 is rotatably mounted on the lower surface of the mounting platform 2. Specifically, a hanging plate 10 is fixed to the lower surface of the mounting platform 2, and the hanging plate 10 corresponds to the nozzle 31. The adjustment body 331 is rotatably connected to the corresponding hanging plate 10 on the mounting platform 2 via a hinge shaft. The rotation axis of the adjustment body 331 is set horizontally, making it perpendicular to the rotation axis of the mounting platform 2. The nozzle 31 is fixedly mounted on the corresponding adjustment body 331. Since the nozzle 31 is connected to the oil supply hose 13, the oil supply hose 13 can adapt to the adjustment of the nozzle 31 angle. In other embodiments, to further improve the flexibility of oiling, the hanging plate 10 can be slidably mounted vertically below the mounting platform 2 using a drive component such as a cylinder, thereby allowing the height of a single nozzle 31 to be adjusted individually as needed.

[0043] Reference Figure 2 and Figure 3 The rotary drive component 332 corresponds one-to-one with the adjusting body 331. The rotary drive component 332 is fixedly mounted on the corresponding hanging plate 10 and is used to drive the corresponding adjusting body 331 to rotate. The rotary drive component 332 is communicatively connected to the control mechanism. Specifically, the rotary drive component 332 can be a micro stepper motor, a micro servo motor, or a micro motor. The hinge shaft of the adjusting body 331 is directly coaxially connected to the output shaft of the rotary drive component 332. Furthermore, the output shaft of the rotary drive component 332 can also be connected to the hinge shaft of the adjusting body 331 through a gear transmission mechanism. The gear transmission mechanism includes a first gear and a second gear. The first gear is connected to the output shaft of the rotary drive component 332, and the second gear is coaxially connected to the hinge shaft of the adjusting body 331. The first gear and the second gear mesh, and the number of teeth of the first gear is less than the number of teeth of the second gear. By driving the adjusting body 331, the nozzle 31 is rotated around the horizontal axis, thereby adjusting the spray pitch angle of the nozzle 31. An angle sensor is provided on the rotary drive 332 or the rotary drive 332 is connected to an encoder to feed back the actual angle of the nozzle 31 to the control mechanism.

[0044] During operation, the rotation of the mounting gimbal 2 and the rotation of the adjusting body 331 allow for multi-degree-of-freedom angle adjustment of each nozzle 31, which helps ensure that the release agent is sprayed onto the inner surface of the mold at the optimal angle.

[0045] Reference Figure 3Furthermore, in this embodiment of the application, to accommodate the rectangular box-shaped mold, three nozzles 31 are provided, namely a first nozzle 6, a second nozzle 7, and a third nozzle 8. The three nozzles 31 are respectively installed on the corresponding adjusting bodies 331, each having an independent metering pump 32 and adjusting assembly 33. Among them, the spray direction of the first nozzle 6 is vertically downward, that is, the spray direction of the first nozzle 6 forms a 0° angle with the vertical plane, and is used to cover the bottom surface and flat areas inside the mold.

[0046] Reference Figure 3 The second nozzle 7 sprays at an angle of 30°-60° to the vertical plane, and is still tilted downwards to cover the inner wall of the mold. The second nozzle 7 effectively coats the inner wall of the mold with oil, ensuring that the mold release agent is covered in the sidewall area.

[0047] Reference Figure 3 The third nozzle 8 has a spray direction at an angle of 70° to 90° to the vertical plane, used to cover the corner areas of the mold. Specifically, the spray direction of the third nozzle 8 is close to horizontal, enabling it to spray the release agent into hard-to-reach areas such as the corners of the mold, effectively solving the problem of insufficient coating in dead corner areas in traditional oiling methods. In other embodiments, the number and angle of the nozzles 31 can be set as needed.

[0048] During the oiling operation, the first nozzle 6, the second nozzle 7, and the third nozzle 8 are selectively opened according to the actual shape of the mold. For example, the first nozzle 6 is used to apply oil to the flat bottom wall of the mold; the second nozzle 7 is used to apply oil to the side walls of the mold; and the third nozzle 8 is used to apply oil to the inside corners and edges of the mold. The control valves of each nozzle 31 are controlled by a control mechanism according to the surface characteristics of the mold in the corresponding section of the oiling path. Furthermore, in actual use, the positions of the first nozzle 6, the second nozzle 7, and the third nozzle 8 can be adjusted by rotating the mounting gimbal 2, and the angles of the first nozzle 6, the second nozzle 7, and / or the third nozzle 8 can be changed by driving the adjusting body 331 to apply oil to different positions.

[0049] Reference Figure 3 and Figure 4 To facilitate the recovery of oil mist during the oiling process and reduce waste to some extent, the oil mist recovery mechanism 4 includes an electrically retractable isolation cover 41, a negative pressure suction assembly (not shown in the figure), and a filter recovery assembly (not shown in the figure). The electrically retractable isolation cover 41 is mounted on the mounting platform 2, and the three nozzles 31 of the oiling mechanism 3 are located inside the electrically retractable isolation cover 41. The retraction direction of the electrically retractable isolation cover 41 is vertical. During the oiling process, the electrically retractable isolation cover 41 descends to form an oiling chamber between itself and the mold, effectively isolating the oiling area from the external environment.

[0050] Reference Figure 4 Specifically, the electric telescopic isolation cover 41 can be a combination of a bellows cover and an electric push rod. The electric push rod is installed on the mounting platform 2. One end of the bellows cover is fixed to the outer circumference of the mounting platform 2, and the other end is connected to the telescopic end of the electric push rod for movement. Alternatively, the electric telescopic isolation cover 41 can also adopt a multi-section sleeve-type electric telescopic structure.

[0051] Reference Figure 4 The negative pressure suction component is connected to the electrically retractable isolation cover 41 and is used to suction oil mist drifting inside the cover 41. Specifically, the negative pressure suction component can be an industrial dust collector, centrifugal fan, negative pressure pump, or vacuum pump, without limitation. Its suction port is located on the electrically retractable isolation cover 41, and the negative pressure suction component is connected to the suction port through a flexible hose. Furthermore, the negative pressure suction component can be integrated into the mounting platform 2 or installed independently of the walking mechanism 1 in the production workshop, without limitation. During operation, the negative pressure suction component creates a micro-negative pressure environment in the oiling chamber, timely suctioning the oil mist generated during the oiling process and preventing oil mist overflow. The suction air volume of the negative pressure suction component is matched according to the volume of the oiling chamber and the rate of oil mist generation.

[0052] Reference Figure 4 The filtration and recovery component is connected to the output end of the negative pressure suction component and is used to filter and recover the oil mist extracted by the negative pressure suction component. Specifically, the filtration and recovery component can adopt an existing multi-stage filter. The structure and principle of multi-stage filters are existing technologies and will not be elaborated here. The filtered clean air is discharged into the workshop environment or recycled. The separated and recovered release agent can be returned to the oil storage tank for reuse, reducing the consumption of release agent. Furthermore, the electric telescopic isolation cover 41, the negative pressure suction component, and the filtration and recovery component are all communicatively connected to the control mechanism.

[0053] Before the oiling operation begins, the control mechanism lowers the electric telescopic isolation cover 41 to be close to the mold to form a semi-enclosed oiling chamber. Then, the negative pressure suction component is activated to establish a negative pressure environment before the oiling operation begins. Through the cooperation of the negative pressure suction component and the filter recovery component, the release agent can be effectively recovered. After the oiling is completed, the electric telescopic isolation cover 41 rises and resets.

[0054] Reference Figure 2 and Figure 4, in order to facilitate detection of the oiled mold surface and identification of missing coating areas, the visual detection mechanism comprises an industrial camera 9 and an image processing unit. Wherein, the industrial camera 9 is mounted on the lifting platform 104 via a support rod 11, and the industrial camera 9 is located at the rear end of the mounting platform 2 in the X-direction movement during the oil coating process, such that the industrial camera 9 is located outside the electric telescopic isolation cover 41, so as to reduce the influence of oil mist on the industrial camera 9. The industrial camera 9 is configured to collect images of the oiled mold surface. Further, the industrial camera 9 can adopt a high-resolution area array camera or a linear array camera, and a polarizing filter can be optionally equipped on the lens of the industrial camera 9 to eliminate the influence of reflection on the mold surface on imaging quality. The industrial camera 9 is equipped with a ring-shaped LED light source or a strip-shaped LED light source to ensure uniform imaging illumination. In other embodiments, the industrial camera 9 can also be mounted on the mounting platform 2 and rotate synchronously with the mounting platform 2; specifically, the industrial camera 9 can be fixedly connected to the mounting platform 2 via the support rod 11, or can be connected to the outer wall of the electric telescopic isolation cover 41 via the support rod 11.

[0055] with reference to Figure 2 and Figure 4 , the image processing unit is in communication connection with the industrial camera 9 and is configured to identify the position coordinates of the missing coating area. The image processing unit can be an independent industrial image processing computer, or can be integrated in the control mechanism, and both the industrial camera 9 and the image processing unit are in communication connection with the control mechanism.

[0056] During operation, the mold surface image collected by the industrial camera 9 is sent to the image processing unit. Based on the differences in color, grayscale or reflection uniformity between the release agent coated area and the uncoated area, the image processing unit adopts an image segmentation algorithm such as threshold segmentation, edge detection or a deep learning semantic segmentation model to identify the coated area and the missing coating area; then, according to the position of the missing coating area in the image, combined with the internal parameter calibration parameters of the industrial camera 9 and the current position coordinates of the traveling mechanism 1, the actual three-dimensional position coordinates of the missing coating area in the mold coordinate system are calculated through coordinate transformation; finally, the position coordinates and area information of the missing coating area are sent to the control mechanism. After the oil coating operation is completed, the control mechanism controls the traveling mechanism 1 to drive the oil coating mechanism 3 to move above the missing coating area according to the recorded coordinates of the missing coating area, and adjusts the angle and flow rate of the nozzle 31 to perform the replenishing coating operation. After the replenishing coating is completed, visual detection can be performed again as needed until the missing coating area is lower than a preset threshold, and then the oil coating can be determined as qualified. Specifically, the visual detection mechanism can detect the oiled mold surface and identify missing coating areas during the oil coating process, or can detect the oiled mold surface and identify missing coating areas after the oil coating is completed.

[0057] The implementation principle of the omnidirectional oiling device in this application embodiment is as follows: the mold is transported to a preset position below the omnidirectional oiling device via a mold conveyor line and positioned and locked. The control mechanism obtains the mold model and position information, and loads the corresponding oiling path and oiling parameters. Specifically, the mold conveyor line can be a roller conveyor line, chain conveyor line, or belt conveyor line. After the mold reaches the preset station, the mold is precisely positioned and fixed by a positioning and locking device such as a clamping cylinder to prevent the mold from moving during the oiling process. The control mechanism can obtain the mold model information by reading the RFID tag on the mold with an RFID reader, scanning the barcode or QR code on the mold with a barcode scanner, obtaining it through image recognition, or manually inputting it by the operator. The control mechanism's database pre-stores the oiling path and oiling parameters corresponding to each mold model. The oiling path includes the X, Y, and Z motion trajectories, and the oiling parameters include the flow rate, angle, and moving speed of each nozzle 31. After obtaining the mold model, the corresponding process parameters are automatically loaded.

[0058] Next, the control mechanism first lowers the electrically retractable isolation cover 41 of the oil mist recovery mechanism 4, forming a semi-enclosed oiling chamber near the mold. Then, the negative pressure suction component is activated to establish a negative pressure environment. Next, the first drive component 105, the second drive component 106, and the third drive component 107 of the walking mechanism 1 are controlled to move in tandem along the oiling path. Simultaneously, the drive source 5 drives the mounting platform 2 to rotate and adjust the oiling direction, the adjustment component 33 adjusts the spray angle of each nozzle 31, and the metering pump 32 adjusts the flow rate of each nozzle 31. The oiling mechanism 3 moves above the mold along the planned path, applying the release agent to the mold surface.

[0059] During the movement of the gimbal 2, the negative pressure suction component continuously draws the dispersed oil mist to the filter and recovery component for recycling, helping to reduce waste. Simultaneously, a vision inspection mechanism monitors the mold surface after oiling in real time and identifies missed areas, while the control mechanism records the coordinates of these missed areas. After oiling is complete, the traveling mechanism 1 plans a recoating path based on the coordinates of the missed areas, ensuring the path only covers those areas to improve work efficiency. The traveling mechanism 1 then moves the oiling mechanism 3 above each missed area, adjusting the angle and flow rate of the required nozzles 31 for precise recoating.

[0060] After the touch-up coating is completed, each drive component of the walking mechanism 1 returns to its initial position, the electric telescopic isolation cover 41 rises and resets, the positioning and locking device releases the mold, the mold conveyor line starts, and the oiled mold is transported to the next process. The oiling device of this application helps to cover the mold surface in all directions, making it less likely to miss the coating. At the same time, it can effectively recover the oil mist that drifts during the spraying process, reducing waste to a certain extent.

[0061] This application also discloses an all-around oiling method for prefabricated component molds. The all-around oiling method uses the aforementioned all-around oiling device and includes the following steps: Step 1: The mold is transported to the preset position under the all-around oiling device by the mold conveyor line and locked in place. The control mechanism obtains the mold model and position information and loads the corresponding oiling path and oiling parameters. Step 2: The walking mechanism 1 drives the mounting gimbal 2 and the oiling mechanism 3 on the mounting gimbal 2 to apply oil along the oiling path. The moving speed and oiling flow rate are automatically matched during oiling. The oiling amount is 5g / m² to 10g / m². During the oiling process, the oil mist recovery mechanism 4 recovers the scattered oil mist. The visual inspection mechanism detects the mold surface after oiling in real time and identifies the missed areas. The control mechanism records the coordinates of the missed areas. Step 3: After the oiling is completed, the traveling mechanism 1 drives the mounting platform 2 and the oiling mechanism 3 to move and re-coat according to the coordinates of the missed areas; Step 4: After the touch-up coating is completed, the walking mechanism 1 is reset, and the mold conveyor line drives the oiled mold into the next process.

[0062] Specifically, in step 1, the control mechanism can obtain the mold model by scanning a code or image recognition. The control system retrieves the corresponding oiling path and oiling parameters from the preset database according to the mold model. The oiling path includes the movement trajectory of the walking mechanism 1 in the X, Y, and Z directions. The oiling parameters include the flow rate and angle of each nozzle 31, as well as the moving speed of the mounting gimbal 2.

[0063] Further, in step 2, the control mechanism first controls the electric telescopic isolation cover 41 of the oil mist recovery mechanism 4 to descend, and the electric telescopic isolation cover 41 approaches the mold to form a semi-closed oiling chamber. Then, the negative pressure suction component is activated to establish a negative pressure environment. Then, the walking mechanism 1 starts from one end of the mold and applies oil along the planned path. The first drive component 105, the second drive component 106, and the third drive component 107 of the walking mechanism 1 move in linkage according to the oiling path. At the same time, the drive source 5 drives the mounting gimbal 2 to rotate and adjust the oiling direction. The control adjustment component 33 adjusts the spray angle of each nozzle 31, and the control metering pump 32 adjusts the flow rate of each nozzle 31. Specifically, the first nozzle 6 is used to apply oil to the flat area of ​​the mold surface, the second nozzle 7 is used to apply oil to the side wall of the mold surface, and the third nozzle 8 is used to apply oil to the inside corner of the mold surface.

[0064] In step 2, the surface of the mold after oiling is detected in real time by a vision inspection mechanism, and the uncoated areas are identified. Specifically, the mold surface image captured in real time by the industrial camera 9 is sent to the image processing unit. The image processing unit identifies the coated area and the uncoated area based on the color, grayscale difference or reflectivity uniformity between the coated and uncoated areas. Then, based on the pixel position of the uncoated area in the image, combined with the intrinsic calibration parameters of the industrial camera 9 and the current position coordinates of the walking mechanism 1, the actual three-dimensional position coordinates of the uncoated area in the mold coordinate system are calculated through coordinate transformation. Finally, the position coordinates and area information of the uncoated area are sent to the control mechanism.

[0065] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
